National estimates indicate that 1.6% of new cases and 12.1% of previously treated cases involve DR-TB, but specific data on its distribution and predictors in Central Uganda are limited. This study aimed to map the spatial and temporal distribution of DR-TB and identify associated risk factors from 2019 to 2023 to guide resource allocation. Methodology A cross-sectional retrospective study was conducted using data from DR-TB treatment centers in Central Uganda from January 2019 to December 2023. R (Version 4.4.0) statistical software and QGIS version 3.36.3 were used for spatial analysis, and significant clusters were identified using SaTscan’s Kulldorff statistic. Multivariable Poisson regression was employed to identify factors associated with DR-TB using STATA version 14. Results Of 803 DR-TB cases, 729 were eligible for analysis. The majority were male (69%), aged 25-34 (34.2%), married (51.9%), and HIV-positive (57.8%). Rifampicin resistance was found in 59% of cases. Kampala and Wakiso had the highest case numbers (30.0% and 24.3%, respectively), with fourteen hotspot clusters identified in these and other districts. Temporal analysis showed fluctuations, peaking in 2019 and 2022. Significant risk factors included age, sex, marital status, occupation, HIV status, and risk group. Conclusion DR-TB in Central Uganda clusters in urban districts, driven by urbanization, population density, and socioeconomic factors. Temporal fluctuations, influenced by disruptions like COVID-19, highlight the need for resilient healthcare systems. Key risk factors such as HIV co-infection, malnutrition, and demographics call for targeted interventions, integrated care, and enhanced surveillance. DR-TB Uganda Central region Spatial and temporal distribution Figures Figure 1 Figure 2 Figure 3 Figure 4 Figure 5 Figure 6 Introduction Tuberculosis remains one of the top infectious disease burdens globally, with an estimated 10 million cases and 1.4 million deaths in 2022 [ 1 ]. DR-TB, defined as a disease caused by TB bacteria that are resistant to at least one of the most effective TB medicines, poses a major challenge to TB control efforts [ 2 ]. In 2022, the World Health Organization (WHO) reported a staggering 465,000 new cases of DR-TB worldwide [ 1 ]. This encompasses the formidable challenges posed by Rifampicin resistance (RR), multidrug-resistant (MDR-TB), and extensively drug-resistant TB. These strains demand complex, and costly treatment regimens, straining healthcare systems across the globe [ 3 ]. The prevalence of DR-TB is increasing in sub-Saharan Africa, including Uganda [ 4 – 6 ]. Though the region is grappling with an array of health challenges, DR-TB looms large on the public health stage. Roughly 4% of new TB cases and a substantial 21% of previously treated cases in Sub-Saharan Africa were estimated to harbor DR-TB [ 7 ]. The high prevalence of HIV co-infection, coupled with resource constraints within healthcare systems, compounds the challenges of combating DR-TB effectively in this region. Uganda is among the 30 highest burden countries, with a prevalence of 201 cases per 100,000 population annually [ 1 ]. However, Uganda faces the additional challenge of rising rates of DR-TB Recent national estimates suggest 5.2% of new TB cases and 14% of retreatment cases in Uganda demonstrating rifampicin resistance, indicating probable DR-TB [ 1 ]. However, subnational variations were apparent, with higher rates concentrated in urban settings. A tertiary hospital in Kampala recorded MDR-TB rates of 10.3% among culture-positive patients [ 8 ]. One local survey in Mbarara Municipality noted 8% MDR-TB prevalence, exceeding national estimates [ 9 ]. In Uganda, the treatment regimen for TB follows the WHO guidelines. For drug-susceptible TB, patients undergo a six-month regimen consisting of an intensive phase of two months with four drugs - isoniazid, rifampicin, pyrazinamide, and ethambutol - followed by a continuation phase of four months with isoniazid and rifampicin. For DR-TB, a more extended and complex regimen is required. Typically, this involves 18–20 months of treatment with second-line drugs, including fluoroquinolones, and second-line injectables. Throughout the treatment, patients are closely monitored for adherence and adverse drug reactions, especially drug toxicity. Regular sputum tests and culture tests are conducted to track progress and ensure the effectiveness of the treatment [ 10 ]. The central region of Uganda has been heavily affected by the HIV epidemic which fuels greater risk of TB co-infection and transmission of drug-resistant strain [ 11 ]. Weak health systems, inadequate patient adherence, and over-the-counter antibiotic access further propagate resistance [ 8 ]. Unfortunately, routine surveillance data on the DR-TB burden in central Uganda specifically has been very limited in recent years. Most epidemiological insights have been derived from small-scale studies at referral facilities. Furthermore, the region’s distinctive sociodemographic composition, varied economic activities, and healthcare infrastructure intricacies shape the complex dynamics of DR-TB within its borders [ 12 ]. Additionally, it receives referrals from other regions because of the existence of national referral hospitals. These patients are added to the central region’s data contributing to the high prevalence attributed to this region [ 13 ]. Despite its pivotal role in Uganda’s healthcare landscape, a conspicuous gap exists in localized data concerning it’s DR-TB. Hence there was an urgent need for updated distribution of DR-TB across central Uganda to guide appropriate public health responses. Spatial epidemiology and geospatial analytics have become pivotal tools for understanding infectious disease transmission dynamics and hotspots [ 14 ]. Techniques like geographic information systems (GIS), cluster and temporal analysis can delineate the geographic distribution of DR-TB. Such approaches have been implemented in varied settings. In China, integration of spatial statistics with electronic surveillance data enabled accurate prediction of MDR-TB probability across provinces [ 15 ]. This facilitated targeted interventions in high-risk areas. In conjunction with spatial and temporal distribution, determining local socio-demographic, clinical factors associated with DR-TB acquisition is essential to shape control strategies to the epidemiological context. But risk factors specifically in central Uganda had been understudied. Therefore, this study generates much-needed evidence on the spatial and temporal distribution, and factors associated with drug-resistant TB in central Uganda. This can chart the scale and distribution of the growing DR-TB threat. Methodology Study area This study was conducted in the central region of Uganda, which is one of the 5 major health regions in the country[16]. It covers an area of 61,403.2Km 2 with over 24 districts and houses over 9.5 million people. The study area included the following 24 districts (Butambala, Gomba, Mpigi, Bukomansibi, Kalangala, Kalungu,Lwengo, Lyantonde, Masaka, Rakai, Sembabule, Wakiso, Buikwe, Buvuma, Kayunga, Kiboga, Kyankwanzi, Luwero, Mityana, Mubende, Mukono, Nakaseke, Nakasongola, and Kampala). The region represents a mix of urban, peri-urban, and rural populations. Kampala, the capital city, located in this region, is the most urban district with a population of over 1.8 million people and a day time population of 2.5 million people [17]. Other large population centers include Mukono, Mpigi, and Wakiso districts neighboring Kampala. The region includes Lake Kyoga along the northern border and inhabits part of the Lake Victoria basin catchment. This area was selected as the study setting given the convergence of urban, agriculture, transport, and population centers which may influence TB transmission dynamics. Out of the 18 DR-TB treatment sites in the country, the region houses Mulago national referral hospital along with other regional referral hospitals: Masaka and Mubende. which serve as DR-TB initiation and treatment centers. These facilities served as sites for key data collection on DR-TB patients. Kampala, the capital city of Uganda is also located in this region. Study Design Across-sectional retrospective study was used to analyze secondary data collected from DR-TB treatment facilities in Central Uganda. This a common and effective approach in epidemiological studies for identifying disease distribution patterns [18] Study population DR-TB patients who visited Mulago National Referral hospital, Masaka and Mubende Regional Referral Hospitals between 2019 and 2023 and their information was present in the registers Inclusion criteria Patients with confirmed DR-TB and was a resident in the central region between January 2021 to December 2023 whose results from drug susceptibility testing (DST) of their sputum collected post screening indicated resistance to any anti- TB drug and were available in the register. Exclusion criteria DR-TB patients who had been referred from other regions. Sample size consideration All the DR-TB patient data collected between January 2019 and December 2023 was sampled and analyzed. This period was selected to provide insights into recent changes in disease patterns, factoring in events like the COVID-19 pandemic, which may have influenced healthcare access and disease incidence. Data collection Data were collected from 1 st April to 30 th April 2024. The study utilized a data extraction tool which was adapted from previous similar studies [19, 20] and modified for this study. All up to date shapefiles of administrative regions in Uganda were obtained from the Uganda Bureau of Statistics [21], these shapefiles included; district, sub-county, and villages. Data analysis Data cleaning was conducted in Microsoft Excel version 19 and SPSS version 25. This involved identifying and addressing inconsistencies, incompleteness, and missingness. Of the 729 DR-TB cases, 64 (8.8%) had missing geographic coordinates, and 102 (14.0%) had incomplete clinical data. Missing geographic coordinates were addressed through geocoding in QGIS version 3.36.3 Clinical data missingness was handled through multiple imputations in SPSS version 25. Data related to demographic characteristics of patients and clinical aspects was analyzed using STATA Version 14. Univariable analysis was conducted to obtain frequencies, percentages, and summary statistics for individual and clinical characteristics. At multivariable analysis, a poisson regression model was fitted, using the backward variable elimination criterion. Variables with high p-values (>0.2) were dropped one by one based on their importance determined by the Wald test. Variable dropping continued until no further improvement is observed in the model. Spatial data analysis involved mapping the geographic distribution of DR-TB cases across the study area using QGIS version 3.36.3 [22] , a powerful open-source GIS software. QGIS enabled the creation of choropleth maps, which visually represented the number of DR-TB cases per district. To assess spatial patterns, the study applied the Global Moran’s Index [23, 24] statistic in QGIS, which determined whether DR-TB cases were randomly distributed across the central region or followed a specific pattern. Moran’s Index helped identify positive spatial autocorrelation, where similar data values (high-high or low-low) clustered geographically, indicating areas of elevated risk. A statistically significant Moran’s Index value (p-value < 0.05, positive Z-score, and above zero) led to the rejection of the null hypothesis, confirming that DR-TB cases were not randomly distributed. To identify hotspots, I used both the Getis-Ord Gi statistic and SaTScan spatial analysis, each applying distinct criteria for hotspot detection. First the investigator calculated the Gi score for each location to assess the clustering of cases in relation to surrounding areas. Statistically significant positive scores indicated hotspots, where high concentrations of cases were spatially clustered compared to neighboring regions. Additionally , to identify significant clusters of DR-TB cases, the study also utilized SaTscan software [25] with the Kulldorff spatial scan statistic [26]. This method scanned spatial windows (initially set at 50% of the study area, later refined to 10%) to detect clusters with a higher-than-expected number of cases. By applying SaTscan, the study pinpointed high-incidence clusters in the region, further refining hotspot identification and providing a robust analysis of spatial clustering patterns. To determine the temporal patterns of DR-TB, R statistical software [27] and STATA (version 14) were utilized [28]. Trends in DR-TB cases were examined over time using R statistical software, which is well-suited for statistical computing and data visualization. Time series plots were generated to visualize the yearly trends of DR-TB cases, revealing patterns and changes over time. The use of R allowed for an effective analysis of the temporal data, with capabilities for advanced plotting and data manipulation. To model the trend and make forecasts, the Auto-Regressive Integrated Moving Average (ARIMA) model was applied using STATA version 14, which provides robust tools for econometric analysis and time series forecasting. The ARIMA model captures the relationship between past values to predict future trends, accounting for autoregression, differencing, and moving average components. The specific parameters of the ARIMA model were chosen based on the Akaike Information Criterion (AIC) to ensure the best fit. STATA’s ARIMA capabilities facilitated accurate trend modeling, enabling insights into future patterns of DR-TB incidence. To assess the significance of the observed trends, a Monte Carlo simulation in STATA was conducted. Monte Carlo simulation is a method of estimating the probability of outcomes by generating random samples based on observed data distribution. In this case, the investigator generated 1,000 random samples based on the mean and standard deviation of the DR-TB cases. By comparing the maximum observed case count with the simulated data, we calculated a p-value, which showed that the observed trend was statistically significant and unlikely due to random chance. Ethical considerations Ethical approval was sought from the School of Public Health Research and Ethics Committee (SPH-REC). Permission to conduct the study at DR-TB treatment centers was sought from hospital directors. Anonymity for extracted data was maintained. Results Demographics and clinical characteristics of study participants The study included a total of 729 DR-TB patients from the central region of Uganda, covering several districts. The age distribution showed that the majority were adults aged 25-34 years (34.2%), significantly more males (69.0%). Over half (51.9%) being married, were engaged in business or trade (32.6%). More than half of the participants (55.7%) had a normal nutritional status, were HIV positive 57.8% The classification of participants based on their TB treatment history revealed that 57.8% were new TB patients, and 57.2% having rifampicin-resistant TB (RR-TB) ( Table 1 and 2 ).

The Global Moran’s I value of 0.33 and the Z-score of 3.81 (P-value < 0.0001) hinting on significant clustering of DR-TB in the study area suggesting that adjacent districts exhibit similar DR-TB incidence rates (Table 4 and Figure 2). Table 4:Moran’s I statistic Moran’s I statistic Expectation Variance Z-score P-Value 0.33 -0.042 0.01 3.81 P<0.0001 Hotspots of DR-TB cases by district in Central region of Uganda The hotspot analysis revealed distinct hotspots, particularly in and around Kampala. The map (Figure 3) indicates that Kampala, highlighted in deep red, is a significant hotspot with a high concentration of DR-TB cases. Clusters of DR-TB disaggregated by village in the central region of Uganda. A total of 24 significant clusters of DR-TB cases in the central region of Uganda. Among these, 14 were identified as hotspot clusters, indicating areas with a significantly higher incidence of DR-TB cases. The most prominent hotspot clusters seen in Kampala district (Kisenyi I, Kosovo, Munyonyo, and Gaba Tr.c D), Wakiso district ( Kabulengwa, Ochieng B, Kyengera Central A and Kitooro Central), Mukono (Kasenge A, Nama, Nanuyenje and Kirondo) and Mubende (Kasaano, Kaweri and Katwe). The remaining 10 clusters were identified as low clusters, shown by blue circles on the map. These clusters represent areas with fewer DR-TB cases than expected, predominantly found in rural areas (Figure 4). Annual trend of DR-TB cases in the central region of Uganda. The yearly trend analysis reveals significant fluctuations in the number of cases recorded each year. In 2019, the number of DR-TB cases was at its peak, with approximately 170 cases recorded. However, in 2020, there was a notable decline in the number of cases, dropping to around 140. The downward trend continued into 2021, reaching the lowest point in the five-year period with about 130 cases. However, in 2022, there was a significant rebound in the number of DR-TB cases, rising back to approximately 160. (Figure 5). Monthly distribution of DR-TB cases in the central region of Uganda between 2019-2023 Analysis revealed significant variations and disruptions in case numbers from January 2019 to early 2020. Starting from March 2020, the dotted line indicates the period when Uganda went into lockdown due to the COVID-19 pandemic whereas full line indicates end of lockdown During the lockdown period, there was a sharp decline in the number of DR-TB cases recorded, and this decline continued into mid-2021. Post-lockdown, from late 2021onwards, the trend shows a gradual recovery with fluctuations in case numbers (Figure 6). Factors associated with DR-TB in the central region of Uganda Individual factors associated with DR-TB in the central region of Uganda Age emerged as a significant factor, with participants aged 25-34 years showing a higher likelihood of DR-TB (aIRR:1.43 CI: 1.11 – 1.78) compared to those aged 14 years or younger. Females exhibited a lower incidence of DR-TB compared to males (aIRR: 0.66, 95% CI: 0.54 - 0.75). Marital status also influenced DR-TB incidence, with married individuals having a higher risk (aIRR: 1.77, 95% CI: 1.49 - 2.09) compared to single individuals. Patients involved in business or trade faced a higher risk (aIRR: 1.51, 95% CI: 1.16 - 1.79) compared to farmers. (Table 5) . Clinical factors associated with DR-TB in the central region of Uganda Patients with moderate acute malnutrition had a higher risk of DR-TB compared to those with normal nutrition, aIRR 1.21 (95% CI: 1.10–1.46). HIV-positive individuals showed a notably higher risk of DR-TB, with an aIRR of 1.36 (95% CI: 1.14–1.65) compared to those who are HIV-negative. Fisherfolk have an aIRR of 1.14 (95% CI: 1.10–1.51), and tobacco users have an aIRR of 1.23 (95% CI: 1.13–1.88) (Table 6) .

Spatial analysis revealed significant clusters, particularly in urban areas, while temporal analysis showed fluctuations influenced by external events such as the COVID-19 pandemic as well as seasonality. Factors including age, sex, marital status, occupation, nutrition status, and HIV status were significantly associated with DR-TB incidence. The spatial analysis identified 24 significant clusters of DR-TB, with 14 high-incidence hotspots primarily in urban centers like Kampala, Wakiso, Mubende and Mukono. The concentration of DR-TB cases in these areas can be attributed to higher population densities, which facilitate the transmission of TB. Additionally, urban areas often have better diagnostic facilities, leading to higher detection rates. A study conducted in Kampala identified urban centers as hotspots for TB due to high population density and improved diagnostic capabilities. This is also consistent with findings from other studies, which also highlighted urbanization and population density as significant predictors of TB incidence [ 29 ]. Additionally, social determinants of health, including poverty and crowded living conditions, prevalent in urban settings, contribute to the higher incidence of DR-TB [ 30 ]. Moreover, urban centers like Kampala have a more transient population, which can lead to increased spread of TB as individuals move between districts. This transient nature, combined with high population density, creates an environment conducive to the rapid spread of DR-TB. Comparatively, rural areas, with lower population densities and less movement, showed fewer cases, aligning with the general understanding that TB transmission rates are lower in less densely populated areas as seen in a study conducted in Zimbabwe [ 31 ]. The temporal analysis revealed fluctuations in DR-TB cases, with notable impacts from the COVID-19 pandemic. The peaks observed during mid-year months, particularly between July and September, could be linked to seasonal factors such as changes in weather conditions, which affect the transmission dynamics of TB. The lockdown period in 2020 saw a sharp decline in the number of DR-TB cases, likely due to disruptions in healthcare services and reduced access to diagnostic facilities. This pattern aligns with global observations where TB case detection declined during the pandemic [ 32 ]. A similar study in Uganda reported a decrease in TB notifications during the COVID-19 lockdown, reflecting the broader impact of the pandemic on TB control programs [ 33 ]. The post-lockdown period showed a recovery in case numbers, indicating the resumption of TB services and increased case detection efforts. The fluctuation in DR-TB cases can also be attributed to changes in healthcare-seeking behavior during the pandemic. Fear of contracting COVID-19 and movement restrictions likely led to fewer individuals seeking medical care, resulting in underreporting of cases. Age was a significant factor, with older age groups showing a higher likelihood of acquiring DR-TB. This finding is consistent with a study conducted in Pakistan, which reported higher DR-TB rates among older populations due to cumulative exposure and longer disease duration [ 34 ]. The increased susceptibility in older age groups is attributed to weakened immune systems and a longer duration of exposure to TB bacteria. Females had a lower incidence of DR-TB compared to males, possibly due to differences in healthcare-seeking behavior. This gender disparity in TB incidence has been documented in other studies in Africa [ 35 , 36 ]. Men are often more likely to engage in behaviors that increase TB risk, such as smoking and working in environments with higher exposure to TB bacteria. Furthermore, the predominance of male participants (69%) aligns with global DR-TB data trends, which suggest higher TB exposure in men due to occupational risks and delayed health-seeking behaviors [ 37 ]. Additionally, women may face barriers to accessing healthcare, leading to underdiagnosis and underreporting of TB cases among females. Marital status influenced DR-TB incidence, with married individuals showing higher risks. This could be related to household transmission dynamics, where close contact with an infected spouse increases the risk of TB transmission. A study in Ethiopia found similar associations between marital status and TB incidence [ 38 ]. Occupation also played a role, with individuals in business or trade having higher risks, potentially due to increased social interactions and mobility. Conversely, unemployed individuals had a lower risk, possibly due to reduced social exposure. Similar findings have been documented in India [ 39 ]. The significant link between moderate acute malnutrition and increased DR-TB risk can be attributed to malnutrition’s weakening effect on immune function, particularly T-cell activity, which is vital for controlling TB infections. This immune suppression heightens susceptibility to TB and its drug-resistant forms. Similar findings have been observed in studies where malnutrition was correlated with higher TB incidence and worse treatment outcomes [ 40 , 41 ]. HIV status was another critical factor, with HIV-negative individuals having a lower risk of DR-TB. The co-infection of HIV and TB is a well-established challenge in Sub-Saharan Africa, exacerbating the TB epidemic due to the immunocompromised status of HIV patients [ 36 ]. HIV-positive individuals are more susceptible to developing TB due to their weakened immune systems, which struggle to control TB bacteria. The elevated DR-TB risk among fisherfolk and tobacco users is likely due to their occupational and lifestyle-related challenges, such as overcrowded living conditions and impaired lung health from smoking, which exacerbate TB exposure and complicate treatment. These observations align with other studies that have identified high-risk groups like fisherfolk and smokers as particularly vulnerable to TB due to environmental and behavioral factors [ 42 , 43 ]. Limitations The study was limited by incomplete and missing data, geographic coordinates were unavailable for 64 cases (8.8%), and clinical data were incomplete for 102 cases (14.0%). While geocoding and multiple imputation methods were applied to address these gaps, imputation may not fully replicate the true underlying data, potentially introducing biases. This missingness could affect the precision of spatial and clinical analyses, limiting the generalizability of findings to the entire DR-TB population in Central Uganda. Additionally, the retrospective analysis limits the ability to establish causal relationships between identified factors and DR-TB incidence, necessitating further longitudinal studies to confirm these associations. Moreover, only a subset of potential predictors of DR-TB identified in the literature were analyzed and not all contextual and environmental factors could be consistently retrieved from existing records. This limitation arose from the reliance on secondary data, which did not include several variables of interest, such as socio-economic factors, and lifestyle choices. The unavailability of these variables in the dataset constrained the analysis, potentially affecting the comprehensiveness of the findings. This study primarily focuses on public DR-TB treatment centers. It does not include private treatment centers like TASO, Baylor, and IDI, which may also manage DR-TB cases. This exclusion could lead to an underestimation of the total burden of DR-TB in the region. Conclusion This study demonstrates that DR-TB in Central Uganda is predominantly clustered in urban districts such as Kampala, Wakiso, Mukono, and Mubende, identifying them as hotspots with higher transmission potential. The spatial autocorrelation confirms non-random clustering, with densely populated urban areas contributing significantly to the spread of DR-TB. Temporal trends revealed a sharp decline in DR-TB cases in 2021, likely due to COVID-19-related disruptions in healthcare services, The findings also highlight a strong association between HIV co-infection and DR-TB. Demographic factors such as younger age, male gender, and marital status further influenced DR-TB risk. Therefore, expanding diagnostic and surveillance capacity in hotspot districts is imperative, with investments in laboratory infrastructure, training of healthcare personnel, and collaboration with local health authorities. Integrating TB and HIV care is critical to manage the high burden of co-infection, while incorporating nutritional support into DR-TB treatment protocols can mitigate the impact of malnutrition on patient outcomes. Strengthening the resilience of TB services is essential to ensure continuity during public health crises, as evidenced by the disruptions during the COVID-19 pandemic. Targeted public health campaigns should prioritize younger men in urban areas, promoting early healthcare-seeking behavior and TB prevention strategies. Furthermore, longitudinal surveillance systems are needed to monitor temporal variations in DR-TB and adapt response strategies accordingly. Research into the role of urbanization, environmental factors such as climate, and the contributions of private healthcare providers to DR-TB management will provide insights to inform more effective, data-driven interventions.

retrospective analysis","fulltext":[{"header":"Introduction","content":"\u003cp\u003eTuberculosis remains one of the top infectious disease burdens globally, with an estimated 10\u0026nbsp;million cases and 1.4\u0026nbsp;million deaths in 2022 [\u003cspan citationid=\"CR1\" class=\"CitationRef\"\u003e1\u003c/span\u003e]. DR-TB, defined as a disease caused by TB bacteria that are resistant to at least one of the most effective TB medicines, poses a major challenge to TB control efforts [\u003cspan citationid=\"CR2\" class=\"CitationRef\"\u003e2\u003c/span\u003e]. In 2022, the World Health Organization (WHO) reported a staggering 465,000 new cases of DR-TB worldwide [\u003cspan citationid=\"CR1\" class=\"CitationRef\"\u003e1\u003c/span\u003e]. This encompasses the formidable challenges posed by Rifampicin resistance (RR), multidrug-resistant (MDR-TB), and extensively drug-resistant TB. These strains demand complex, and costly treatment regimens, straining healthcare systems across the globe [\u003cspan citationid=\"CR3\" class=\"CitationRef\"\u003e3\u003c/span\u003e].\u003c/p\u003e \u003cp\u003eThe prevalence of DR-TB is increasing in sub-Saharan Africa, including Uganda [\u003cspan additionalcitationids=\"CR5\" citationid=\"CR4\" class=\"CitationRef\"\u003e4\u003c/span\u003e\u0026ndash;\u003cspan citationid=\"CR6\" class=\"CitationRef\"\u003e6\u003c/span\u003e]. Though the region is grappling with an array of health challenges, DR-TB looms large on the public health stage. Roughly 4% of new TB cases and a substantial 21% of previously treated cases in Sub-Saharan Africa were estimated to harbor DR-TB [\u003cspan citationid=\"CR7\" class=\"CitationRef\"\u003e7\u003c/span\u003e]. The high prevalence of HIV co-infection, coupled with resource constraints within healthcare systems, compounds the challenges of combating DR-TB effectively in this region.\u003c/p\u003e \u003cp\u003eUganda is among the 30 highest burden countries, with a prevalence of 201 cases per 100,000 population annually [\u003cspan citationid=\"CR1\" class=\"CitationRef\"\u003e1\u003c/span\u003e]. However, Uganda faces the additional challenge of rising rates of DR-TB\u003c/p\u003e \u003cp\u003eRecent national estimates suggest 5.2% of new TB cases and 14% of retreatment cases in Uganda demonstrating rifampicin resistance, indicating probable DR-TB [\u003cspan citationid=\"CR1\" class=\"CitationRef\"\u003e1\u003c/span\u003e]. However, subnational variations were apparent, with higher rates concentrated in urban settings. A tertiary hospital in Kampala recorded MDR-TB rates of 10.3% among culture-positive patients [\u003cspan citationid=\"CR8\" class=\"CitationRef\"\u003e8\u003c/span\u003e]. One local survey in Mbarara Municipality noted 8% MDR-TB prevalence, exceeding national estimates [\u003cspan citationid=\"CR9\" class=\"CitationRef\"\u003e9\u003c/span\u003e].\u003c/p\u003e \u003cp\u003e In Uganda, the treatment regimen for TB follows the WHO guidelines. For drug-susceptible TB, patients undergo a six-month regimen consisting of an intensive phase of two months with four drugs - isoniazid, rifampicin, pyrazinamide, and ethambutol - followed by a continuation phase of four months with isoniazid and rifampicin. For DR-TB, a more extended and complex regimen is required. Typically, this involves 18\u0026ndash;20 months of treatment with second-line drugs, including fluoroquinolones, and second-line injectables. Throughout the treatment, patients are closely monitored for adherence and adverse drug reactions, especially drug toxicity. Regular sputum tests and culture tests are conducted to track progress and ensure the effectiveness of the treatment [\u003cspan citationid=\"CR10\" class=\"CitationRef\"\u003e10\u003c/span\u003e].\u003c/p\u003e \u003cp\u003eThe central region of Uganda has been heavily affected by the HIV epidemic which fuels greater risk of TB co-infection and transmission of drug-resistant strain [\u003cspan citationid=\"CR11\" class=\"CitationRef\"\u003e11\u003c/span\u003e]. Weak health systems, inadequate patient adherence, and over-the-counter antibiotic access further propagate resistance [\u003cspan citationid=\"CR8\" class=\"CitationRef\"\u003e8\u003c/span\u003e]. Unfortunately, routine surveillance data on the DR-TB burden in central Uganda specifically has been very limited in recent years. Most epidemiological insights have been derived from small-scale studies at referral facilities.\u003c/p\u003e \u003cp\u003eFurthermore, the region\u0026rsquo;s distinctive sociodemographic composition, varied economic activities, and healthcare infrastructure intricacies shape the complex dynamics of DR-TB within its borders [\u003cspan citationid=\"CR12\" class=\"CitationRef\"\u003e12\u003c/span\u003e]. Additionally, it receives referrals from other regions because of the existence of national referral hospitals.

Moran\u0026rsquo;s Index helped identify positive spatial autocorrelation, where similar data values (high-high or low-low) clustered geographically, indicating areas of elevated risk. A statistically significant Moran\u0026rsquo;s Index value (p-value \u0026lt; 0.05, positive Z-score, and above zero) led to the rejection of the null hypothesis, confirming that DR-TB cases were not randomly distributed.\u003c/p\u003e\n\u003cp\u003eTo identify hotspots, I used both the Getis-Ord Gi statistic and SaTScan spatial analysis, each applying distinct criteria for hotspot detection.\u003c/p\u003e\n\u003cp\u003eFirst the investigator calculated the Gi score for each location to assess the clustering of cases in relation to surrounding areas.

By applying SaTscan, the study pinpointed high-incidence clusters in the region, further refining hotspot identification and providing a robust analysis of spatial clustering patterns.\u0026nbsp;\u003c/p\u003e\n\u003cp\u003eTo determine the temporal patterns of DR-TB, R statistical software [27] and STATA (version 14) were utilized [28].\u0026nbsp;Trends in DR-TB cases were examined over time using R statistical software, which is well-suited for statistical computing and data visualization. Time series plots were generated to visualize the yearly trends of DR-TB cases, revealing patterns and changes over time. The use of R allowed for an effective analysis of the temporal data, with capabilities for advanced plotting and data manipulation.\u003c/p\u003e\n\u003cp\u003eTo model the trend and make forecasts, the Auto-Regressive Integrated Moving Average (ARIMA) model was applied using STATA version 14, which provides robust tools for econometric analysis and time series forecasting. The ARIMA model captures the relationship between past values to predict future trends, accounting for autoregression, differencing, and moving average components. The specific parameters of the ARIMA model were chosen based on the Akaike Information Criterion (AIC) to ensure the best fit. STATA\u0026rsquo;s ARIMA capabilities facilitated accurate trend modeling, enabling insights into future patterns of DR-TB incidence.\u003c/p\u003e\n\u003cp\u003eTo assess the significance of the observed trends, a Monte Carlo simulation in STATA was conducted. Monte Carlo simulation is a method of estimating the probability of outcomes by generating random samples based on observed data distribution. In this case, the investigator generated 1,000 random samples based on the mean and standard deviation of the DR-TB cases. By comparing the maximum observed case count with the simulated data, we calculated a p-value, which showed that the observed trend was statistically significant and unlikely due to random chance.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eEthical considerations\u003c/strong\u003e\u003c/p\u003e\n\u003cp\u003eEthical approval was sought from the School of Public Health Research and Ethics Committee (SPH-REC).

DR-TB in the central region of Uganda from 2019 to 2023, identifying key demographic and clinical factors associated with DR-TB incidence. Spatial analysis revealed significant clusters, particularly in urban areas, while temporal analysis showed fluctuations influenced by external events such as the COVID-19 pandemic as well as seasonality. Factors including age, sex, marital status, occupation, nutrition status, and HIV status were significantly associated with DR-TB incidence.\u003c/p\u003e \u003cp\u003eThe spatial analysis identified 24 significant clusters of DR-TB, with 14 high-incidence hotspots primarily in urban centers like Kampala, Wakiso, Mubende and Mukono. The concentration of DR-TB cases in these areas can be attributed to higher population densities, which facilitate the transmission of TB. Additionally, urban areas often have better diagnostic facilities, leading to higher detection rates. A study conducted in Kampala identified urban centers as hotspots for TB due to high population density and improved diagnostic capabilities. This is also consistent with findings from other studies, which also highlighted urbanization and population density as significant predictors of TB incidence [\u003cspan citationid=\"CR29\" class=\"CitationRef\"\u003e29\u003c/span\u003e]. Additionally, social determinants of health, including poverty and crowded living conditions, prevalent in urban settings, contribute to the higher incidence of DR-TB [\u003cspan citationid=\"CR30\" class=\"CitationRef\"\u003e30\u003c/span\u003e].\u003c/p\u003e \u003cp\u003eMoreover, urban centers like Kampala have a more transient population, which can lead to increased spread of TB as individuals move between districts. This transient nature, combined with high population density, creates an environment conducive to the rapid spread of DR-TB. Comparatively, rural areas, with lower population densities and less movement, showed fewer cases, aligning with the general understanding that TB transmission rates are lower in less densely populated areas as seen in a study conducted in Zimbabwe [\u003cspan citationid=\"CR31\" class=\"CitationRef\"\u003e31\u003c/span\u003e].\u003c/p\u003e \u003cp\u003eThe temporal analysis revealed fluctuations in DR-TB cases, with notable impacts from the COVID-19 pandemic. The peaks observed during mid-year months, particularly between July and September, could be linked to seasonal factors such as changes in weather conditions, which affect the transmission dynamics of TB. The lockdown period in 2020 saw a sharp decline in the number of DR-TB cases, likely due to disruptions in healthcare services and reduced access to diagnostic facilities. This pattern aligns with global observations where TB case detection declined during the pandemic [\u003cspan citationid=\"CR32\" class=\"CitationRef\"\u003e32\u003c/span\u003e]. A similar study in Uganda reported a decrease in TB notifications during the COVID-19 lockdown, reflecting the broader impact of the pandemic on TB control programs [\u003cspan citationid=\"CR33\" class=\"CitationRef\"\u003e33\u003c/span\u003e]. The post-lockdown period showed a recovery in case numbers, indicating the resumption of TB services and increased case detection efforts.\u003c/p\u003e \u003cp\u003eThe fluctuation in DR-TB cases can also be attributed to changes in healthcare-seeking behavior during the pandemic. Fear of contracting COVID-19 and movement restrictions likely led to fewer individuals seeking medical care, resulting in underreporting of cases.\u003c/p\u003e \u003cp\u003eAge was a significant factor, with older age groups showing a higher likelihood of acquiring DR-TB. This finding is consistent with a study conducted in Pakistan, which reported higher DR-TB rates among older populations due to cumulative exposure and longer disease duration [\u003cspan citationid=\"CR34\" class=\"CitationRef\"\u003e34\u003c/span\u003e]. The increased susceptibility in older age groups is attributed to weakened immune systems and a longer duration of exposure to TB bacteria.\u003c/p\u003e \u003cp\u003eFemales had a lower incidence of DR-TB compared to males, possibly due to differences in healthcare-seeking behavior. This gender disparity in TB incidence has been documented in other studies in Africa [\u003cspan citationid=\"CR35\" class=\"CitationRef\"\u003e35\u003c/span\u003e, \u003cspan citationid=\"CR36\" class=\"CitationRef\"\u003e36\u003c/span\u003e]. Men are often more likely to engage in behaviors that increase TB risk, such as smoking and working in environments with higher exposure to TB bacteria. Furthermore, the predominance of male participants (69%) aligns with global DR-TB data trends, which suggest higher TB exposure in men due to occupational risks and delayed health-seeking behaviors [\u003cspan citationid=\"CR37\" class=\"CitationRef\"\u003e37\u003c/span\u003e]. Additionally, women may face barriers to accessing healthcare, leading to underdiagnosis and underreporting of TB cases among females.\u003c/p\u003e \u003cp\u003eMarital status influenced DR-TB incidence, with married individuals showing higher risks. This could be related to household transmission dynamics, where close contact with an infected spouse increases the risk of TB transmission. A study in Ethiopia found similar associations between marital status and TB incidence [\u003cspan citationid=\"CR38\" class=\"CitationRef\"\u003e38\u003c/span\u003e]. Occupation also played a role, with individuals in business or trade having higher risks, potentially due to increased social interactions and mobility. Conversely, unemployed individuals had a lower risk, possibly due to reduced social exposure. Similar findings have been documented in India [\u003cspan citationid=\"CR39\" class=\"CitationRef\"\u003e39\u003c/span\u003e].\u003c/p\u003e \u003cp\u003eThe significant link between moderate acute malnutrition and increased DR-TB risk can be attributed to malnutrition\u0026rsquo;s weakening effect on immune function, particularly T-cell activity, which is vital for controlling TB infections. This immune suppression heightens susceptibility to TB and its drug-resistant forms. Similar findings have been observed in studies where malnutrition was correlated with higher TB incidence and worse treatment outcomes [\u003cspan citationid=\"CR40\" class=\"CitationRef\"\u003e40\u003c/span\u003e, \u003cspan citationid=\"CR41\" class=\"CitationRef\"\u003e41\u003c/span\u003e].\u003c/p\u003e \u003cp\u003eHIV status was another critical factor, with HIV-negative individuals having a lower risk of DR-TB. The co-infection of HIV and TB is a well-established challenge in Sub-Saharan Africa, exacerbating the TB epidemic due to the immunocompromised status of HIV patients [\u003cspan citationid=\"CR36\" class=\"CitationRef\"\u003e36\u003c/span\u003e]. HIV-positive individuals are more susceptible to developing TB due to their weakened immune systems, which struggle to control TB bacteria.\u003c/p\u003e \u003cp\u003eThe elevated DR-TB risk among fisherfolk and tobacco users is likely due to their occupational and lifestyle-related challenges, such as overcrowded living conditions and impaired lung health from smoking, which exacerbate TB exposure and complicate treatment. These observations align with other studies that have identified high-risk groups like fisherfolk and smokers as particularly vulnerable to TB due to environmental and behavioral factors [\u003cspan citationid=\"CR42\" class=\"CitationRef\"\u003e42\u003c/span\u003e, \u003cspan citationid=\"CR43\" class=\"CitationRef\"\u003e43\u003c/span\u003e].\u003c/p\u003e \u003cdiv id=\"Sec23\" class=\"Section2\"\u003e \u003ch2\u003eLimitations\u003c/h2\u003e \u003cp\u003eThe study was limited by incomplete and missing data, geographic coordinates were unavailable for 64 cases (8.8%), and clinical data were incomplete for 102 cases (14.0%). While geocoding and multiple imputation methods were applied to address these gaps, imputation may not fully replicate the true underlying data, potentially introducing biases. This missingness could affect the precision of spatial and clinical analyses, limiting the generalizability of findings to the entire DR-TB population in Central Uganda. Additionally, the retrospective analysis limits the ability to establish causal relationships between identified factors and DR-TB incidence, necessitating further longitudinal studies to confirm these associations.\u003c/p\u003e \u003cp\u003eMoreover, only a subset of potential predictors of DR-TB identified in the literature were analyzed and not all contextual and environmental factors could be consistently retrieved from existing records. This limitation arose from the reliance on secondary data, which did not include several variables of interest, such as socio-economic factors, and lifestyle choices. The unavailability of these variables in the dataset constrained the analysis, potentially affecting the comprehensiveness of the findings.\u003c/p\u003e \u003cp\u003eThis study primarily focuses on public DR-TB treatment centers. It does not include private treatment centers like TASO, Baylor, and IDI, which may also manage DR-TB cases. This exclusion could lead to an underestimation of the total burden of DR-TB in the region.\u003c/p\u003e \u003c/div\u003e"},{"header":"Conclusion","content":"\u003cp\u003eThis study demonstrates that DR-TB in Central Uganda is predominantly clustered in urban districts such as Kampala, Wakiso, Mukono, and Mubende, identifying them as hotspots with higher transmission potential. The spatial autocorrelation confirms non-random clustering, with densely populated urban areas contributing significantly to the spread of DR-TB. Temporal trends revealed a sharp decline in DR-TB cases in 2021, likely due to COVID-19-related disruptions in healthcare services, The findings also highlight a strong association between HIV co-infection and DR-TB. Demographic factors such as younger age, male gender, and marital status further influenced DR-TB risk. Therefore, expanding diagnostic and surveillance capacity in hotspot districts is imperative, with investments in laboratory infrastructure, training of healthcare personnel, and collaboration with local health authorities. Integrating TB and HIV care is critical to manage the high burden of co-infection, while incorporating nutritional support into DR-TB treatment protocols can mitigate the impact of malnutrition on patient outcomes. Strengthening the resilience of TB services is essential to ensure continuity during public health crises, as evidenced by the disruptions during the COVID-19 pandemic. Targeted public health campaigns should prioritize younger men in urban areas, promoting early healthcare-seeking behavior and TB prevention strategies. Furthermore, longitudinal surveillance systems are needed to monitor temporal variations in DR-TB and adapt response strategies accordingly. Research into the role of urbanization, environmental factors such as climate, and the contributions of private healthcare providers to DR-TB management will provide insights to inform more effective, data-driven interventions.\u003c/p\u003e"},{"header":"Abbreviations","content":"\u003cp\u003eAIDs:\u0026nbsp;Acquired Immunodeficiency Syndrome\u003c/p\u003e\n\u003cp\u003eDR -TB: Drug Resistant Tuberculosis\u003c/p\u003e\n\u003cp\u003eGIS: Geographical Information System\u0026nbsp;\u003c/p\u003e\n\u003cp\u003eMDR-TB: Multi Drug Resistant Tuberculosis\u003c/p\u003e\n\u003cp\u003eTB: Tuberculosis\u003c/p\u003e\n\u003cp\u003eWHO: World Health Organization\u003c/p\u003e"},{"header":"Declarations","content":"\u003cp\u003e\u003cstrong\u003eEthics and Approval:\u0026nbsp;\u003c/strong\u003eEthical approval was obtained from the School of Public Health Research and Ethics Committee (SPH-REC).

National estimates indicate that 1.6% of new cases and 12.1% of previously treated cases involve DR-TB, but specific data on its distribution and predictors in Central Uganda are limited. This study aimed to map the spatial and temporal distribution of DR-TB and identify associated risk factors from 2019 to 2023 to guide resource allocation.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eMethodology\u003c/strong\u003e\u003c/p\u003e\n\u003cp\u003eA cross-sectional retrospective study was conducted using data from DR-TB treatment centers in Central Uganda from January 2019 to December 2023. R (Version 4.4.0) statistical software and QGIS version 3.36.3 were used for spatial analysis, and significant clusters were identified using SaTscan’s Kulldorff statistic. Multivariable Poisson regression was employed to identify factors associated with DR-TB using STATA version 14.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eResults\u003c/strong\u003e\u003c/p\u003e\n\u003cp\u003eOf 803 DR-TB cases, 729 were eligible for analysis. The majority were male (69%), aged 25-34 (34.2%), married (51.9%), and HIV-positive (57.8%). Rifampicin resistance was found in 59% of cases. Kampala and Wakiso had the highest case numbers (30.0% and 24.3%, respectively), with fourteen hotspot clusters identified in these and other districts. Temporal analysis showed fluctuations, peaking in 2019 and 2022. Significant risk factors included age, sex, marital status, occupation, HIV status, and risk group.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eConclusion\u003c/strong\u003e\u003c/p\u003e\n\u003cp\u003eDR-TB in Central Uganda clusters in urban districts, driven by urbanization, population density, and socioeconomic factors.
