In Saudi Arabia, the incidence of cancer is rising, and there is a critical need for cardio-oncology services to address cancer treatment-related cardiovascular toxicity. This study aimed to evaluate the knowledge and practices of healthcare providers (HCPs) in Saudi Arabia regarding cardio-oncology. Methods: A cross-sectional study was conducted from January to April 2024 using an online survey targeting cardiologists, oncologists, and clinical pharmacists. The survey assessed demographics, perceptions of cardio-oncology, availability of services, and current practices. Data were analyzed using descriptive statistics, chi-squared tests, and bivariate analyses. Results: The survey received responses from 116 HCPs, including cardiologists (63.79%), oncologists (23.28%), and clinical pharmacists (12.93%). Most participants had over six years of experience, and only one had formal cardio-oncology training. While 84.48% recognized the importance of managing cardiac complications in cancer patients, only 42.24% were familiar with existing guidelines. Limited training programs and institutional resources were significant barriers to implementing cardio-oncology services. Despite agreement on the need for cardiotoxicity management, only one-third recommended cardioprotective agents as standard care. Conclusion: There is a notable deficiency in formal training and resources for cardio-oncology in Saudi Arabia. To bridge this gap, integrating cardio-oncology into training programs, establishing institutional guidelines, and adopting multidisciplinary care models are crucial. These measures will enhance the quality of care for cancer patients and improve their cardiovascular outcomes. Figures Figure 1 Figure 2 Figure 3 Introduction The oncology field is witnessing a rapid evolution in systemic therapy regimens and guidelines globally[ 1 ]. In 2020 alone, 17,631 newly diagnosed cases of cancer were reported to the Saudi Cancer Registry, with the most common being breast, colorectal then thyroid cancers[ 2 ]. With improvements in cancer management resulting in decreasing cancer-related mortality rates, the management of cardiovascular diseases and accessibility to cardiovascular care have become increasingly paramount[ 3 ]. Despite advancements in medical care, cancer and cardiovascular diseases remain prominent causes of mortality globally[ 4 ]. As cancer and cardiovascular disease both share similar risk factors, such as increasing age, smoking, alcohol use, and high BMI[ 5 – 8 ], this contributes to the rising prevalence of both diseases. This is further complicated by the fact that it has been well-established that cancer treatments can cause cancer treatment-related cardiovascular toxicity (CTR-CVT)[ 9 , 10 ]. Since then, it has been suggested that cardiotoxic cancer medications can be divided into drugs that can potentially cause irreversible damage (Type I) and drugs that predominantly induce reversible dysfunction (Type II)[ 11 ]. Cardio-oncology has emerged as an expanding specialty dedicated to providing cardiovascular care for both active cancer patients and cancer survivors in direct response to the increasing requirements of this population[ 1 ]. The scope of cardio-oncology encompasses optimizing pre-cancer treatment, diagnosing, and managing cardiac complications resulting from cancer treatment both during and after the completion of cancer therapy. Although numerous cardio-oncology programs have emerged to address these demands, they remain predominantly confined to larger institutions, often serving as academic referral centers. Over the years, several international organizations, including the American Society of Clinical Oncology (ASCO), the European Society of Cardiology (ESC), and the National Comprehensive Cancer Network (NCCN), have issued several position statements and guidelines pertaining to the detection and management of cancer treatment-related cardiac dysfunction (CTRCD)[ 11 – 13 ]. However, cardio-oncology is still an emerging field. Due to a lack of training programs, it is unclear how well-trained healthcare providers (HCPs) are in this subspecialty. In a survey of 106 cardiovascular specialists in the United States, published in the Journal of American College of Cardiology, over 43% of respondents had no dedicated cardio-oncology training programs for cardiology fellows in their institutions[ 14 ]. Notably, in Saudi Arabia, cardio-oncology programs have been limitedly implemented thus far, and few to no formal training programs in the field are available. Thus, this research aims to assess the practical knowledge of HCPs, including cardiologists, oncologists, and clinical pharmacists, on cardio-oncology in Saudi Arabia. This would inform healthcare providers on how to better improve the quality of life of their patients and the care provided to them. Methods Study Design and Subjects A cross-sectional study was conducted in Saudi Arabia between January 2024 and April 2024. An online survey was created in English using Google Forms and distributed via email and social media platforms such as WhatsApp platform. The survey targeted physicians and clinical pharmacists specializing in oncology or cardiology. The survey was accompanied by a cover letter that described the research study's objective and targeted population, and participants were given access to the survey after accepting participation. The survey was created by two oncologists and two cardiologists specializing in cardio-oncology. It had been previously validated and used internationally in a study conducted by Peng et al. in 2019. The survey was obtained with the corresponding author's permission[ 15 ]. The study received Institutional Review Board (IRB) approval from King Abdullah International Medical Research Center at National Guard Health Affairs in Riyadh, Saudi Arabia (IRB/2930/23). Questionnaire Items The survey comprised seven sections, including multiple-choice and Likert scale questions and two clinical scenarios. It consisted of a total of 45 questions, with 13 of them for oncologists and five for cardiologists. The first section collected the participants’ demographics and respondents. The second section evaluated the participants’ perceptions of cardio-oncology, for instance, inquiring about one’s definition of “cardio-oncology”. The third section assessed the availability of cardio-oncology services at participants’ institutions. The fourth section collected opinions regarding the current practices in the cardio-oncology field. It aimed to evaluate the perceived importance of oncologists in considering cardiotoxicity during different stages of cancer therapy, such as planning, utilization, and completion, and how it affects their decision-making processes. It also assessed participants’ opinions on whether cancer patients would benefit from cardiologists' involvement and cardio-oncology clinics. The fifth section of the questionnaire is directed explicitly to cardiologists. This section assessed cardiologists' knowledge and comfort level in recognizing and managing cardiotoxicity. Additionally, it aimed to determine their perception of the skills and expertise possessed by their oncology colleagues in dealing with cardiotoxicity-related issues. The following section of the questionnaire was designed solely for oncologists to assess their knowledge and comfort level in identifying and managing cardiotoxicity. In addition, it aimed to determine their perspective on the skill of their cardiology colleagues in dealing with cardiotoxicity-related cancer therapy. The last section presented two clinical scenarios of common cardiotoxicity issues in oncology to assess participants' ability to apply their knowledge. Statistical Analysis Descriptive quantitative analysis was generated via the “response” feature in Google Forms. Chi-squared test was used to compare categorical variables, and bivariate analysis was used to examine associations between the dependent and independent variables. The response rate was not obtainable, given the survey was distributed online. Statistical analyses were conducted using Excel software version 16.88. Results Demographics of respondents and experience in practice A total of 116 HCPs in Saudi Arabia participated in the survey. Most respondents were cardiologists (63.79%), followed by oncologists (23.28%), and clinical pharmacists specializing in cardiology and oncology (12.93%). Nearly more than half of the respondents were from the central region of Saudi Arabia (67.24%). The majority of participants had over six years of experience (80.68%). Out of the respondents, only one physician received formal training in cardio-oncology. Additionally, 87.07% of the practitioners worked in tertiary hospitals (Table 1 ). Table 1 Demographics of healthcare professionals surveyed (n = 116) Region n % Central region 78 67.24 Eastern region 18 15.52 Western region 11 9.48 Northern region 4 3.45 Southern region 5 4.31 Specialty Cardiology phis 74 63.79 Oncology/hematology 27 23.28 Clinical Pharmacist in cardiology field 8 6.90 Clinical Pharmacist in oncology/hematology field 7 6.03 Current position Consultant (physician or pharmacist) 88 48.35 Staff physician 8 4.40 Senior pharmacist 5 2.75 Fellow 12 6.59 Medical Resident 3 1.65 Years practice of consultant (physician or pharmacist) 0–5 years 17 19.32 6–10 years 19 21.59 11–20 years 32 36.36 > 20 years 20 22.73 Practice location description Tertiary care hospital 101 87.07 Secondary hospital 11 9.48 Private clinic/hospital 4 3.45 Percentage of time spent on clinical research Less than 10% 60 51.72 10–20% 31 26.72 20–30% 15 12.93 30–40% 4 3.45 40–50% 1 0.86 More than 50% 5 4.31 Perception of cardio-oncology and cardiotoxicity Regarding the HCP’s perception towards cardio-oncology, the respondents had the chance to respond to this question with multiple choice questions where multiple answers were accepted. The majority of respondents believed cardio-oncology means managing cancer patients who are experiencing cardiac complications secondary to cancer therapy (84.48%). Furthermore, more than (80%) believed cardio-oncology is about recognizing patients at high risk of developing cardiotoxicity from cancer treatment and diagnosing cardiotoxicity induced by cancer treatment (83.62 and 82.76%, respectively) (Fig. 1 ). Regarding the HCPs perception towards the most significant risk of cardiotoxicity induced by cancer treatment,=70.69%) of respondents believe that targeted agents (such as trastuzumab) induced cardiotoxicity could be experienced during cancer treatment. In addition, 56.90% believe that chemotherapy-induced cardiotoxicity could develop during cancer treatment (Table 2 ). Table 2 Perceptions of cardiotoxicity risk The greatest risk of experiencing cardiotoxicity from chemotherapy (e.g. anthracyclines), n (%) During cancer treatment (chemotherapy and/or targeted agents) 66 (56.9) One-year post-cancer therapy (short-term risk) 42 (36.21) One to five years post-cancer therapy 48 (41.38) Greater than five years post-cancer therapy (long-term risk) 52 (44.83) The greatest risk of experiencing cardiotoxicity from targeted therapies (e.g. trastuzumab), n (%) During cancer treatment (chemotherapy and/or targeted agents) 82 (70.69) One year post-cancer therapy (short-term risk) 26 (22.42) One to five years post-cancer therapy 39 (33.63) Greater than five years post-cancer therapy (long-term risk) 32 (27.59) Almost 42.24% of respondents reported being familiar with guidelines from expert societies on the directions and management of cardiovascular toxicity. Out of the reported societies, the ESC was the most recognized guideline (58.93%) by the respondents (Fig. 2 ). Availability of cardio-oncology services at respondents' institution This survey assessed the availability of educational programs in cardio-oncology. The most frequent answer regarding educational programs was “there is little cardiology training for clinical cardiology fellows” (36.21%). Interestingly, 31.9% of respondents reported the lack of program availability at all. Regarding cardio-oncology services offered currently at respondents' institutions, almost half of the respondents reported providing such services on a consultation-based model (55.18%). Reflecting on the potential obstacles to the development of cardio-oncology units, “limited interest” was the most frequent answer (40.52%) reported by the respondents, followed by “limited funding” and “limited infrastructure” (28.45%, 25%) (Table 3 ). Table 3 Availability of cardio-oncology services at respondents' institution Education programs are available in the field of cardio-oncology, n (%) There is little cardio-oncology training for clinical cardiology fellows 42 (36.21) Cardiology fellows are exposed to cardio-oncology during clinical rotations as part of the curriculum 9 (7.76) There are some lectures on cardio-oncology as part of the core curriculum or CME offerings 22 (18.97) Cardiology fellows can choose to spend time training with the oncology service, but this is not part of the core curriculum 6 (5.18) There is a dedicated cardio-oncology fellowship program (at least 6 months) 1 (0.87) I am unsure of available cardio-oncology programs 38 (32.76) No available programs at all 37 (31.9) Cardio-oncology services are currently offered Consultation service operated by general cardiologists for assessment and management of cardiotoxicity among cancer patients 64 (55.18) Physicians specialized in the field of cardio-oncology who are comfortable managing cardio-toxic side effects due to cancer therapy and can give recommendations for adjusting cancer therapy 3 (2.59) Clinical pharmacists in the field of cardio-oncology who are comfortable managing cardio-toxic side effects due to cancer therapy and can give recommendations for adjusting cancer therapy 5 (4.32) Cardio-oncology services are not currently present and there are no plans to add these services 10 (8.63) Cardio-oncology services are not currently present but there are plans to add these services within the year 7 (6.04) I am unsure of the available services 27 (23.28) Potential obstacles to the development of cardio-oncology units Limited funding 33 (28.45) Limited infrastructure 29 (25) Limited need 7 (6.04) Limited interest 47 (40.52) No obstacle 32 (27.59) Respondents' opinions towards current practice In the current study, both cardiologists and oncologists agreed on the importance of oncologists' consideration of cardiotoxicity when planning treatment plans (82.93% and 79.41% respectively). Furthermore, both specialist groups agreed on the importance of monitoring for possible cardiac adverse events during active cancer treatments (85.37% and 76.47% respectively). For cancer survivors, both groups agreed that oncologists should consider possible cardiac complications induced by cancer treatment exposure (58.54% and 55.88 respectively). Half of the respondents believed in the involvement of cardiologists in providing ongoing monitoring for cardiotoxicity, even if the patient has no clinical symptoms of cardiac issues. On a scale of 5, 34.15% of cardiologists strongly agree on using cardioprotective agents as a standard of care while 35% of oncologists were neutral about this statement. The majority of respondents (87.93%) thought that access to cardio-oncology services would not change the prognosis of cancer patients. In the setting of metastatic cancer, more cardiologists (7.32%) accepted a higher risk of cardiotoxicity (> 15% risk) compared to oncologists (0%) ( Figure. 3 ), However, both oncologists and cardiologists accepted cardiotoxicity ranging between 5–15%. Current Practice of Respondents Cardiologists' responses to the statement “I am knowledgeable about cardiovascular complications of cancer therapy” were mostly neutral (41.46%) followed by agreement (37.80%). There was an agreement among cardiologists about their comfort in treating cardiovascular complications induced by cancer therapy, where most of them responded as neutral, agree, and strongly agree (28.05%, 32.93%, and 25.61%, respectively). In addition to that, cardiologists' responses were mostly neutral when asked how oncologists are knowledgeable and comfortable with managing cardiovascular toxicities of cancer therapy (42.68% and 31.71%, respectively). Almost 40% of cardiologists reported that they sometimes prescribe cardiac medications to manage patients with cardiotoxicities as a result of cancer therapy. When it comes to oncologists' practice, almost 70% of oncologists feel comfortable treating cardiovascular toxicities induced by cancer therapy. In addition to that, 50% of them feel comfortable managing such cases. Furthermore, 44.12% of oncologists were neutral when asked “whether cardiologists are knowledgeable about these toxicities” and 35.29% agreed that cardiologists are comfortable managing such cases., Moreover, 33.8% of oncologists responded that they ask all cancer patients about cardiovascular risk factors prior to starting any cancer therapy. Similar to cardiologists, almost 40% of oncologists reported that they sometimes prescribe cardiac medications to patients with cardiovascular toxicities. Discussion The advancements in cancer therapy in recent years have contributed to increased overall survival in various cancer types, creating a population with emerging medical needs, including cardio-oncology care[ 16 ]. Several studies have been conducted to describe the cardio-oncology landscape among patients with cancer in Saudi Arabia. A single-center retrospective analysis that was conducted in Najran identified cardiac toxicity in around 15% of their cancer patient population[ 17 ]. Similarly, a larger retrospective analysis by Aljazairi and colleagues included over 1000 patients who received trastuzumab, pertuzumab, and bevacizumab; cardiovascular toxicities were detected in around 16% of their patient population[ 18 ]. A recent guideline update by the Saudi Heart Association expanded recommendations to focus on special populations, including oncology patients, to further accommodate the growing needs of patients living with cancer[ 19 ]. To our knowledge, this study is the first to capture the current state of cardio-oncology practices among healthcare providers in Saudi Arabia to help address knowledge gaps, educational and training needs in the country. Our survey was completed by 116 HCPs, most of whom were cardiology specialists. Most respondents had over five years of clinical experience and practiced in tertiary care institutions. Notably, out of the 116 responders, only one physician received formal cardio-oncology training, which reflects the current limited state of exposure to the field during residency and fellowship training. Most respondents were able to identify the growing role of cardio-oncology care and the major cardiovascular offenders, such as trastuzumab and anthracyclines. On the other hand, less than half of the respondents identified relevant information sources to refer back to, which is a considerable limitation to the provision of cardio-oncology care. This can be improved by setting institutional practice guidelines and introducing national and international practice guidelines in the field of cardio-oncology in training programs and academic curriculums. The American College of Cardiology established a framework for cardio-oncology subspecialty fellowship programs; it outlines the different levels of competency a program should offer, which range from a basic understanding of cardio-oncology concepts to rigorous coverage in cardio-oncology specialized clinics[ 20 ]. Multiple healthcare systems in the United States have shared successful experiences in implementing specialized training programs; several aspects can be adopted in Saudi Arabia, such as cross-training in specialized institutions and increasing focus on multidisciplinary care models[ 21 , 22 ]. The survey our study was adopted from Peng et al study, hence we compared results of our study Peng et al[ 15 ] which reveals several important similarities, and differences. While our study focused on a specific region, Saudi Arabia, and targeted cardiologists and oncologists, Peng et al.'s study had a broader geographic scope, including participants from 22 countries across multiple continents. This broader scope allowed Peng et al. to capture a more diverse range of practices and opinions, while our study provided a more focused insight into the cardio-oncology landscape within Saudi Arabia. In terms of demographics, both studies reported a higher participation rate among cardiologists than oncologists. When comparing perceptions of cardio-oncology and cardiotoxicity, both studies revealed that the majority of respondents recognized the importance of managing cardiac complications secondary to cancer therapy and the need for cardiologists' involvement in cancer care. However, Peng et al. found a more significant disparity between cardiologists and oncologists regarding when and how cardiologists should be involved in cancer patient care. Moreover, the availability of cardio-oncology services and training programs was a common concern in both studies. Peng et al. highlighted limited funding and infrastructure as significant barriers to the development of cardio-oncology clinics globally, whereas our study found that limited interest was a major obstacle in Saudi Arabia. Furthermore, the majority of respondents have highlighted the limited cardio-oncology services at their respective institutions. The barriers to establishing a specialized service were thought to be limited financial and administrative resources. Recommendations from a consolidated framework for implementation research (CFIR) model performed at an academic medical center in the United States may be utilized to help guide the implementation of cardio-oncology services in Saudi Arabia; this includes standardization of referral processes and integrating decision-making tools in electronic health records[ 23 ]. Another positive experience in implementing specialized cardio-oncology services was reported by the Iraqi Cardio-Oncology Program-Pharmacist (ICOP-Pharm). The ICOP model integrates experienced clinical pharmacists in direct patient care as a part of a multidisciplinary care team; this allowed better drug therapy optimization and helped cardiologists manage a larger number of patients[ 24 ]. Metastatic cancer disease survival has increased significantly over the last few years in which common cancer diseases such as metastatic colorectal, and breast cancers have median survival of more than 2–3 years[ 25 – 26 ]. The results of our study indicate that in the setting of metastatic cancer, a higher percentage of cardiologists were willing to accept a cardiotoxicity risk greater than 15%, whereas none of the oncologists were willing to accept this level of risk. This finding is particularly noteworthy as it suggests that oncologists may be less willing to accept higher cardiotoxicity risks in these patients because many of them can maintain a good quality of life during their extended survival period. In contrast, cardiologists might be more inclined to accept higher risks, potentially due to limited awareness of the significant improvements in survival rates and quality of life for these patients. This difference in perception demonstrates the need for better interdisciplinary communication and education to align treatment goals and risk assessments between cardiologists and oncologists, ensuring that patients receive the most appropriate care tailored to their long-term survival prospects. Survey domains evaluating current practices have shown a general agreement on considering potential cardiotoxicities in oncology patients and the involvement of cardiology in managing patients who develop toxicities. However, one-third of respondents actively recommend cardioprotective agents in the care process. The described practice is consistent with the ESC cardio-oncology guidelines, which suggests only considering cardioprotective strategies in high-risk subsets of patients based on small clinical trials[ 12 ]. Surprisingly, over 80% of responders thought that cardio-oncology care will not change cancer prognosis. In addition, there seems to be a gap in cardiovascular risk factor screenings in oncology patients undergoing therapy. These interesting results indicate that cancer and cardiovascular disease are viewed as separate disease states rather than a part of the oncology disease continuum; this further confirms the need for robust cardio-oncology services since several large studies have shown increased cardiovascular disease incidence and mortality in patients with cancer compared to the general population[ 16 , 27 – 34 ]. This nationwide study has several limitations. First, the survey was distributed on a large scale via link distribution, limiting our ability to assess the survey response rate. The majority of respondents were practicing in academic and tertiary care centers in the central region of Saudi Arabia, which limits the generalizability of these results to smaller healthcare settings. Conclusion The study highlights a significant knowledge gap and limited exposure to cardio-oncology among HCPs in Saudi Arabia. Despite recognizing the importance of managing cardiotoxicity in cancer patients, formal training and comprehensive cardio-oncology services remain limited. Implementing institutional guidelines, integrating cardio-oncology into medical education, and adopting multidisciplinary care models are essential to improve patient outcomes and address the growing needs of cancer patients at risk of cardiovascular complications.

In 2020 alone, 17,631 newly diagnosed cases of cancer were reported to the Saudi Cancer Registry, with the most common being breast, colorectal then thyroid cancers[\u003cspan citationid=\"CR2\" class=\"CitationRef\"\u003e2\u003c/span\u003e]. With improvements in cancer management resulting in decreasing cancer-related mortality rates, the management of cardiovascular diseases and accessibility to cardiovascular care have become increasingly paramount[\u003cspan citationid=\"CR3\" class=\"CitationRef\"\u003e3\u003c/span\u003e]. Despite advancements in medical care, cancer and cardiovascular diseases remain prominent causes of mortality globally[\u003cspan citationid=\"CR4\" class=\"CitationRef\"\u003e4\u003c/span\u003e].\u003c/p\u003e \u003cp\u003eAs cancer and cardiovascular disease both share similar risk factors, such as increasing age, smoking, alcohol use, and high BMI[\u003cspan additionalcitationids=\"CR6 CR7\" citationid=\"CR5\" class=\"CitationRef\"\u003e5\u003c/span\u003e\u0026ndash;\u003cspan citationid=\"CR8\" class=\"CitationRef\"\u003e8\u003c/span\u003e], this contributes to the rising prevalence of both diseases. This is further complicated by the fact that it has been well-established that cancer treatments can cause cancer treatment-related cardiovascular toxicity (CTR-CVT)[\u003cspan citationid=\"CR9\" class=\"CitationRef\"\u003e9\u003c/span\u003e, \u003cspan citationid=\"CR10\" class=\"CitationRef\"\u003e10\u003c/span\u003e]. Since then, it has been suggested that cardiotoxic cancer medications can be divided into drugs that can potentially cause irreversible damage (Type I) and drugs that predominantly induce reversible dysfunction (Type II)[\u003cspan citationid=\"CR11\" class=\"CitationRef\"\u003e11\u003c/span\u003e].\u003c/p\u003e \u003cp\u003eCardio-oncology has emerged as an expanding specialty dedicated to providing cardiovascular care for both active cancer patients and cancer survivors in direct response to the increasing requirements of this population[\u003cspan citationid=\"CR1\" class=\"CitationRef\"\u003e1\u003c/span\u003e]. The scope of cardio-oncology encompasses optimizing pre-cancer treatment, diagnosing, and managing cardiac complications resulting from cancer treatment both during and after the completion of cancer therapy. Although numerous cardio-oncology programs have emerged to address these demands, they remain predominantly confined to larger institutions, often serving as academic referral centers.\u003c/p\u003e \u003cp\u003eOver the years, several international organizations, including the American Society of Clinical Oncology (ASCO), the European Society of Cardiology (ESC), and the National Comprehensive Cancer Network (NCCN), have issued several position statements and guidelines pertaining to the detection and management of cancer treatment-related cardiac dysfunction (CTRCD)[\u003cspan additionalcitationids=\"CR12\" citationid=\"CR11\" class=\"CitationRef\"\u003e11\u003c/span\u003e\u0026ndash;\u003cspan citationid=\"CR13\" class=\"CitationRef\"\u003e13\u003c/span\u003e]. However, cardio-oncology is still an emerging field. Due to a lack of training programs, it is unclear how well-trained healthcare providers (HCPs) are in this subspecialty. In a survey of 106 cardiovascular specialists in the United States, published in the Journal of American College of Cardiology, over 43% of respondents had no dedicated cardio-oncology training programs for cardiology fellows in their institutions[\u003cspan citationid=\"CR14\" class=\"CitationRef\"\u003e14\u003c/span\u003e].\u003c/p\u003e \u003cp\u003eNotably, in Saudi Arabia, cardio-oncology programs have been limitedly implemented thus far, and few to no formal training programs in the field are available. Thus, this research aims to assess the practical knowledge of HCPs, including cardiologists, oncologists, and clinical pharmacists, on cardio-oncology in Saudi Arabia. This would inform healthcare providers on how to better improve the quality of life of their patients and the care provided to them.\u003c/p\u003e"},{"header":"Methods","content":"\u003cdiv id=\"Sec3\" class=\"Section2\"\u003e \u003ch2\u003eStudy Design and Subjects\u003c/h2\u003e \u003cp\u003eA cross-sectional study was conducted in Saudi Arabia between January 2024 and April 2024. An online survey was created in English using Google Forms and distributed via email and social media platforms such as WhatsApp platform. The survey targeted physicians and clinical pharmacists specializing in oncology or cardiology. The survey was accompanied by a cover letter that described the research study's objective and targeted population, and participants were given access to the survey after accepting participation. The survey was created by two oncologists and two cardiologists specializing in cardio-oncology. It had been previously validated and used internationally in a study conducted by Peng et al. in 2019.

It consisted of a total of 45 questions, with 13 of them for oncologists and five for cardiologists. The first section collected the participants\u0026rsquo; demographics and respondents. The second section evaluated the participants\u0026rsquo; perceptions of cardio-oncology, for instance, inquiring about one\u0026rsquo;s definition of \u0026ldquo;cardio-oncology\u0026rdquo;. The third section assessed the availability of cardio-oncology services at participants\u0026rsquo; institutions. The fourth section collected opinions regarding the current practices in the cardio-oncology field. It aimed to evaluate the perceived importance of oncologists in considering cardiotoxicity during different stages of cancer therapy, such as planning, utilization, and completion, and how it affects their decision-making processes. It also assessed participants\u0026rsquo; opinions on whether cancer patients would benefit from cardiologists' involvement and cardio-oncology clinics. The fifth section of the questionnaire is directed explicitly to cardiologists. This section assessed cardiologists' knowledge and comfort level in recognizing and managing cardiotoxicity. Additionally, it aimed to determine their perception of the skills and expertise possessed by their oncology colleagues in dealing with cardiotoxicity-related issues. The following section of the questionnaire was designed solely for oncologists to assess their knowledge and comfort level in identifying and managing cardiotoxicity. In addition, it aimed to determine their perspective on the skill of their cardiology colleagues in dealing with cardiotoxicity-related cancer therapy.

Notably, out of the 116 responders, only one physician received formal cardio-oncology training, which reflects the current limited state of exposure to the field during residency and fellowship training. Most respondents were able to identify the growing role of cardio-oncology care and the major cardiovascular offenders, such as trastuzumab and anthracyclines. On the other hand, less than half of the respondents identified relevant information sources to refer back to, which is a considerable limitation to the provision of cardio-oncology care. This can be improved by setting institutional practice guidelines and introducing national and international practice guidelines in the field of cardio-oncology in training programs and academic curriculums. The American College of Cardiology established a framework for cardio-oncology subspecialty fellowship programs; it outlines the different levels of competency a program should offer, which range from a basic understanding of cardio-oncology concepts to rigorous coverage in cardio-oncology specialized clinics[\u003cspan citationid=\"CR20\" class=\"CitationRef\"\u003e20\u003c/span\u003e]. Multiple healthcare systems in the United States have shared successful experiences in implementing specialized training programs; several aspects can be adopted in Saudi Arabia, such as cross-training in specialized institutions and increasing focus on multidisciplinary care models[\u003cspan citationid=\"CR21\" class=\"CitationRef\"\u003e21\u003c/span\u003e, \u003cspan citationid=\"CR22\" class=\"CitationRef\"\u003e22\u003c/span\u003e].\u003c/p\u003e \u003cp\u003eThe survey our study was adopted from Peng et al study, hence we compared results of our study Peng et al[\u003cspan citationid=\"CR15\" class=\"CitationRef\"\u003e15\u003c/span\u003e] which reveals several important similarities, and differences. While our study focused on a specific region, Saudi Arabia, and targeted cardiologists and oncologists, Peng et al.'s study had a broader geographic scope, including participants from 22 countries across multiple continents. This broader scope allowed Peng et al. to capture a more diverse range of practices and opinions, while our study provided a more focused insight into the cardio-oncology landscape within Saudi Arabia. In terms of demographics, both studies reported a higher participation rate among cardiologists than oncologists. When comparing perceptions of cardio-oncology and cardiotoxicity, both studies revealed that the majority of respondents recognized the importance of managing cardiac complications secondary to cancer therapy and the need for cardiologists' involvement in cancer care. However, Peng et al. found a more significant disparity between cardiologists and oncologists regarding when and how cardiologists should be involved in cancer patient care. Moreover, the availability of cardio-oncology services and training programs was a common concern in both studies. Peng et al. highlighted limited funding and infrastructure as significant barriers to the development of cardio-oncology clinics globally, whereas our study found that limited interest was a major obstacle in Saudi Arabia.\u003c/p\u003e \u003cp\u003eFurthermore, the majority of respondents have highlighted the limited cardio-oncology services at their respective institutions. The barriers to establishing a specialized service were thought to be limited financial and administrative resources. Recommendations from a consolidated framework for implementation research (CFIR) model performed at an academic medical center in the United States may be utilized to help guide the implementation of cardio-oncology services in Saudi Arabia; this includes standardization of referral processes and integrating decision-making tools in electronic health records[\u003cspan citationid=\"CR23\" class=\"CitationRef\"\u003e23\u003c/span\u003e]. Another positive experience in implementing specialized cardio-oncology services was reported by the Iraqi Cardio-Oncology Program-Pharmacist (ICOP-Pharm). The ICOP model integrates experienced clinical pharmacists in direct patient care as a part of a multidisciplinary care team; this allowed better drug therapy optimization and helped cardiologists manage a larger number of patients[\u003cspan citationid=\"CR24\" class=\"CitationRef\"\u003e24\u003c/span\u003e].\u003c/p\u003e \u003cp\u003eMetastatic cancer disease survival has increased significantly over the last few years in which common cancer diseases such as metastatic colorectal, and breast cancers have median survival of more than 2\u0026ndash;3 years[\u003cspan citationid=\"CR25\" class=\"CitationRef\"\u003e25\u003c/span\u003e\u0026ndash;\u003cspan citationid=\"CR26\" class=\"CitationRef\"\u003e26\u003c/span\u003e]. The results of our study indicate that in the setting of metastatic cancer, a higher percentage of cardiologists were willing to accept a cardiotoxicity risk greater than 15%, whereas none of the oncologists were willing to accept this level of risk. This finding is particularly noteworthy as it suggests that oncologists may be less willing to accept higher cardiotoxicity risks in these patients because many of them can maintain a good quality of life during their extended survival period. In contrast, cardiologists might be more inclined to accept higher risks, potentially due to limited awareness of the significant improvements in survival rates and quality of life for these patients. This difference in perception demonstrates the need for better interdisciplinary communication and education to align treatment goals and risk assessments between cardiologists and oncologists, ensuring that patients receive the most appropriate care tailored to their long-term survival prospects.\u003c/p\u003e \u003cp\u003eSurvey domains evaluating current practices have shown a general agreement on considering potential cardiotoxicities in oncology patients and the involvement of cardiology in managing patients who develop toxicities. However, one-third of respondents actively recommend cardioprotective agents in the care process. The described practice is consistent with the ESC cardio-oncology guidelines, which suggests only considering cardioprotective strategies in high-risk subsets of patients based on small clinical trials[\u003cspan citationid=\"CR12\" class=\"CitationRef\"\u003e12\u003c/span\u003e]. Surprisingly, over 80% of responders thought that cardio-oncology care will not change cancer prognosis. In addition, there seems to be a gap in cardiovascular risk factor screenings in oncology patients undergoing therapy. These interesting results indicate that cancer and cardiovascular disease are viewed as separate disease states rather than a part of the oncology disease continuum; this further confirms the need for robust cardio-oncology services since several large studies have shown increased cardiovascular disease incidence and mortality in patients with cancer compared to the general population[\u003cspan citationid=\"CR16\" class=\"CitationRef\"\u003e16\u003c/span\u003e, \u003cspan additionalcitationids=\"CR28 CR29 CR30 CR31 CR32 CR33\" citationid=\"CR27\" class=\"CitationRef\"\u003e27\u003c/span\u003e\u0026ndash;\u003cspan citationid=\"CR34\" class=\"CitationRef\"\u003e34\u003c/span\u003e].\u003c/p\u003e \u003cp\u003eThis nationwide study has several limitations. First, the survey was distributed on a large scale via link distribution, limiting our ability to assess the survey response rate.

In Saudi Arabia, the incidence of cancer is rising, and there is a critical need for cardio-oncology services to address cancer treatment-related cardiovascular toxicity. This study aimed to evaluate the knowledge and practices of healthcare providers (HCPs) in Saudi Arabia regarding cardio-oncology.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eMethods: \u003c/strong\u003eA cross-sectional study was conducted from January to April 2024 using an online survey targeting cardiologists, oncologists, and clinical pharmacists. The survey assessed demographics, perceptions of cardio-oncology, availability of services, and current practices. Data were analyzed using descriptive statistics, chi-squared tests, and bivariate analyses.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eResults: \u003c/strong\u003eThe survey received responses from 116 HCPs, including cardiologists (63.79%), oncologists (23.28%), and clinical pharmacists (12.93%). Most participants had over six years of experience, and only one had formal cardio-oncology training. While 84.48% recognized the importance of managing cardiac complications in cancer patients, only 42.24% were familiar with existing guidelines. Limited training programs and institutional resources were significant barriers to implementing cardio-oncology services. Despite agreement on the need for cardiotoxicity management, only one-third recommended cardioprotective agents as standard care.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eConclusion: \u003c/strong\u003eThere is a notable deficiency in formal training and resources for cardio-oncology in Saudi Arabia. To bridge this gap, integrating cardio-oncology into training programs, establishing institutional guidelines, and adopting multidisciplinary care models are crucial. These measures will enhance the quality of care for cancer patients and improve their cardiovascular outcomes.\u003c/p\u003e","manuscriptTitle":"Assessment of Cardio-Oncology Knowledge and Practice among Healthcare Providers in Saudi Arabia: A Comprehensive Nationwide Survey","msid":"","msnumber":"","nonDraftVersions":[{"code":1,"date":"2024-10-17 08:47:13","doi":"10.21203/rs.3.rs-4959562/v1","editorialEvents":[{"type":"communityComments","content":0},{"type":"decision","content":"Revision requested","date":"2024-12-17T17:20:11+00:00","index":"","fulltext":""},{"type":"editorInvitedReview","content":"","date":"2024-11-10T07:52:21+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"291761569080551360144286053424836237985","date":"2024-11-10T05:35:10+00:00","index":"hide","fulltext":""},{"type":"reviewersInvited","content":"","date":"2024-09-06T19:25:17+00:00","index":"","fulltext":""},{"type":"editorAssigned","content":"","date":"2024-08-29T19:18:58+00:00","index":"","fulltext":""},{"type":"checksComplete","content":"","date":"2024-08-27T12:08:40+00:00","index":"","fulltext":""},{"type":"submitted","content":"Cardio-Oncology","date":"2024-08-22T16:54:30+00:00","index":"","fulltext":""}],"status":"published","journal":{"display":true,"email":"
