This paper examines factors associated with induced demand for healthcare services within Iran’s healthcare system, using high-level analysis of service utilization patterns to identify what correlates with patients receiving additional care beyond underlying need. It synthesizes healthcare system characteristics and utilization influences to characterize when and why induced demand occurs. A key caveat is that the study’s observational framing limits causal inference, and the paper relies on the availability and structure of the data used to measure service use. The paper does not explicitly discuss endometriosis or adenomyosis; it was included in the corpus via a keyword match in the upstream search index.

Abstract

Background:  One of the most important subjects in health economics and healthcare management is the theory of induced demand; that is, caring for or providing and selling unnecessary services to users of healthcare systems, which is accompanied by the exercising of power by the service providers. Methods: : This study was performed on physicians, nurses, and laboratory and radiology technicians working in Medical Science universities. Random sampling was conducted from five areas: the center, north, west, east and south of Iran. Data were gathered by a questionnaire, with a Cronbach's alpha of >0.7, consisting of nine dimensions on existence of induced demand and its associated factors. Results: : The results showed that overall, 65.2% of the participants agreed with the existence of induced demand . Chi-squared test showed there was no difference in the level of induced demand between the regions of the country, education level and occupation. However, there was a significant difference in terms of gender ( P <0.005 ). The Kruskal-Wallis test indicated a significant relationship between the associated factors and induced demand ( P <0.005 ). Conclusions: : Results showed that induced demand was influenced by factors including service recipients’ awareness, personal benefits of service providers, the extent they cared about health, supervision of insurance companies, industrialization of the health sector, diversity and increased number of trained experts and the quality of methods of training the service providers.  Therefore, policymakers and planners should consider raising awareness of health service recipients, supervising insurance companies, reforming teaching methods, social culture making and changing the beliefs of society.

F1000Research 2018, 7 :978 ( https://doi.org/10.12688/f1000research.14377.1 ) First published: 02 Jul 2018, 7 :978 ( https://doi.org/10.12688/f1000research.14377.1 ) Latest published: 02 Jul 2018, 7 :978 ( https://doi.org/10.12688/f1000research.14377.1 ) Introduction The provision of healthcare services is faced with serious challenges due to economic factors such as the adequacy or lack of financial resources, access to technology and medical equipment, and social determinants of health 1 . Adverse selection, moral hazard and induced demand are three important phenomena that affect patients' behavior 2 . Among these, induced demand is an issue that economists consider to have side effects and to affect interactions between patient and physician. Economic transactions generally involve two parties, a seller and a buyer. However, demand from patients (as buyers) in the health sector is mediated by other factors (i.e. physicians and sometimes healthcare agencies 3 . In fact, induced demand is defined as inducing caring for or providing and selling unnecessary services to clients of healthcare system that is accompanied with exercise of power by the service providers. This may result in providing services that do not have a positive impact on the health of the client 4 . The phenomenon of induced demand supplier; in other words, the information asymmetry between the service provider and the customer or service applicant in the healthcare market due to the poor knowledge of patients, the importance of health and concern over the consequences of diseases, clients tend to comply with the orders of the service providers 5 . For example, some patients assume that the services provided in hospitals are of higher quality than those in clinics, and prefer to be treated in hospitals even if treatment is available in clinics 6 . The assumption of asymmetric information between the physician and patient is the background for the induced demand theory 7 . The induced demand hypothesis emphasizes the motivations of doctors as healthcare providers to create induced demand 8 . The patients also affect the induction of demand as they have unlimited desire for, and tendency toward, services 9 . Moreover, economic incentives focused on insurance can affect patients’ behavior and the profit of healthcare organizations 10 . Many studies have confirmed physicians' induced demand, identified and investigated various supply and demand factors 11 – 15 . A study by Bogg et al in India showed that the government's financial support has resulted in induced demand 7 . Recent studies also demonstrated the impact of physicians’ payment mechanisms on motivating health-seeking behavior in patients 16 . A study by Karimi et al showed that induced demand for medical and pharmaceutical services is more common among general physicians 17 . Cutler et al revealed a correlation between causes of induced demand from patients and physicians in providing services in different regions 18 . A study by Yuda showed that a 1% reduction in medical costs by the service providers could increase induced demand for services by up to 7.5% 19 . In their study in France, Delattre and Dormont showed that increasing the number of physicians relative to the population reduced the number of patients seeking medical advice/counseling; however, this reduction was minimal and a decline in the number of consulting physicians did not increase the volume of medical services sought 20 . A study in Italy by Magazzino and Mele showed that the gross national product, unemployment rate, number of hospital beds, degree of urbanization and percentage of the population with high school education had a significant direct impact on health expenditure 21 . The issue of induced demand is highly complicated due to the information asymmetry in medical services 22 . The possibility of induced demand and the severity of its effects are associated with interactions between a wide range of factors that affect patients’ behavior, including market, behavior, rules and regulations. These factors could act as incentives and disincentives for patients’ participation in or resistance against the phenomenon of induced demand 4 . Considering the extent of factors affecting induced demand and lack of a comprehensive study on this issue in Iran, the purpose of this paper is to examine the factors of knowledge and awareness of service providers, the personal interests of service providers, their sensitivity to health, the supervision of insurance companies, the industrialization of the health sector, the increase and diversity and the number of specialist forces and the quality of practices training to providers in hospitals. Methods Study design, setting and participants This applied, cross-sectional, descriptive-analytical study was conducted from January to December 2015 in a number of health centers and hospitals in Iran. Overall, 511 subjects consisting of 78 physicians, 350 nurses, 26 laboratory experts and 28 radiology technicians were included in this study. The subjects were selected by a mixed sampling method, which included stratified random sampling (the country was classified into five regions: center, north, west, east and south) and cluster sampling of levels was conducted within hospitals and health centers (each center or hospital was considered as a single cluster). The centers and hospitals studied were as follows: North: Imam Khomeini Hospital (Sari), Imam Reza Hospital affiliated to Sari University of Medical Sciences (Amol), 5 th Azar Hospital (Gorgan), Shahid Sayad Shirazi Hospital affiliated to Golestan University of Medical Sciences (Gorgan). South: Golestan Hospital affiliated to Ahvaz University of Medical Sciences (Ahvaz). East: Imam Reza Hospital (Mashhad), Rasool-e-Akram Hospital (Zabol). West: Imam Khomeini Hospital affiliated to Ardebil University of Medical Sciences (Ardebil). Center: Rasool-e-Akram Hospital affiliated to Iran University of Medical Sciences (Tehran). Finally, sampling within clusters was done by classification per ratio of physicians, nurses, laboratory experts and radiology technicians working in the medical centers. The main goal of the study was to determine the demand induction rate of services in Iran's health system and its related factors. The following formula was used to calculate the sample size, with a correction factor of 1.25 used for more precision. n 0 = Z 1– α /2 2 ∗ P ∗ ( 1–p) d 2 = 1.96 2 ∗ 0.5 2 ∗ 0.5 2 0 .05 2 = 385 n = 1.25 ∗ n 0 = 1.25 ∗ 385 = 482 At least 480 samples were selected for this study, consisting of 350 females (72.9%) and 130 (27.1%) males aged 22–57 years. Inclusion criteria consisted of at least 6 months of work experience and willingness to participate in the study. Data collection Data were collected by a questionnaire ( Supplementary File 1 ), which consisted of two parts: (a) background characteristics and (b) factors affecting induced demand for health services. The individuals completed the questionnaires in writing in the presence of the researcher. This questionnaire contains 33 items and 9 dimensions and uses the Likert scale. The items have 5 options that are as follows: I totally agree with the highest score (score of 1), I agree score of 2), I somewhat agree (score of 3), I disagree (score 4), and I totally disagree with the lowest score (score of 5). The dimension of service recipients’ awareness had 3 related item with the minimum score of 3 and maximum score of 15, the dimension of the extent the service providers cared about their health had 8 related item with a minimum score of 8 and maximum score of 40, the dimension of supervision and planning of insurance companies had 3 related item with the minimum score of 3 and maximum score of 15, the dimension of personal benefits of service providers had 3 related item with the minimum score of 3 and maximum score of 15, the dimension of industrialization of the health sector had 3 related item with the minimum score of 12 and maximum score of 20, the dimension of diversity and increased number of trained experts had 4 related item with the minimum score of 4 and maximum score of 20, the dimension of service providers’ awareness had 3 related item with the minimum score of 3 and maximum score of 15, the dimension of quality of models and methods used for training service providers had 3 related item with the minimum score of 3 and maximum score of 15, and the total score of questionnaire ranged between 33 and 165. The validity and reliability of the questionnaire was confirmed by a Master's thesis (S. Montazeri, Master’s thesis). The scientific validity of its contents was verified by 10 faculty members. Cronbach's alpha of 0.80 was achieved in a preliminary study on 30 samples. Cronbach's alpha of more than 0.7 was achieved for the nine dimensions. Table 1 shows the dimensions of the questionnaire of induced demand for health services in Iran. Table 1. Dimensions of the questionnaire of induced demand for health services in Iran.

Considering the difference in the number of options and scores of each factor, scores were first converted to a 0–100 scale. Non-parametric tests were used to determine the relationship between factors and induced demand. The Kruskal–Wallis test was used due to absence of normality assumption for factors associated with induced demand. The chi-squared test was also used for data analysis at a significance level of P <0.05. Ethical statement Ethical approval was obtained from the relevant organization (Islamic Azad University of Sari Branch with code of ethics IR.IAU.SARI.REC.1397.7) and written consent of the participants (samples), and they were assured of the confidentiality of all data collected. Results Overall, 511 subjects, who were working in emergency departments (17.9%), wards (71.5%), laboratories (6.8%) and clinics (3.8%), completed the questionnaire. The highest and lowest level of agreement with induced demand was recorded in the west (71%) and south (57.5%) of Iran, respectively. Moreover, 65.2% of the subjects in the whole country agreed with the existence of induced demand, while only 4.4% did not agree with the existence of induced demand. The chi-squared test showed no significant difference between different regions of the country ( Table 2 ). Table 2.

However, there was no significant relationship between education level and induced demand. Laboratory staff (73.1%) and physicians (55.1%) had the highest and lowest level of agreement with the existence of induced demand, respectively. Moreover, 68.1% and 3.8% of the nurses agreed and disagreed with the existence of induced demand, respectively. Furthermore, 57.1% and 4.4% of the radiology technicians agreed and disagreed with the existence of induced demand, respectively. Chi-square test showed no significant relationship between induced demand and job categories ( P =0.194). The results also showed that women (69.4%) agreed significantly more with the existence of induced demand than men (53.8%) ( Table 3 ). The results of this study indicate that 64.9% of the subjects believed that sensitivity of clients toward their own health affected the incidence of induced demand. In addition, 62.1% of the subjects believed that the monitoring and planning of insurance companies affected the incidence of induced demand. Kruskal-Wallis test showed a significant relationship between induced demand and its related factors ( Table 4 ). Table 3.

Responses of all participants to all questions23. Discussion The results of the present study showed that the majority of participants (65.2%) agreed with the existence of induced demand, which is consistent with previous studies 11 – 15 . Bogg et al showed that the government’s financial support has led to induced demand 7 In Japan, Sekimoto and Ii studied the supply and induced demand for chronic diseases, and reported an increase in induced demand for hypertension and diabetes 24 . The findings of Crivellei et al. in Switzerland 25 Delattre and Dormont in France 20 were in line with the results of this study. However, a study in America showed no correlation between demand for services and services provided by physicians through Medicare 26 . A study by Amporfu indicated that salaried physicians have no incentive to induce demand 27 . Although few studies strongly reject the existence of induced demand, some experts believe that identification and determination of the incidence of induced demand are health economics issues due to the complexity of treatment, medical decisions, clinical uncertainty and modernization of health needs. It is not simple to distinguish between real demand and induced demand. In this regard, Richardson and Peacock claimed that medical decision-making is often complex and uncertain even if all medical standards were met 28 . Lien et al also stated that the development of needs, epidemiological changes and diversity of tastes have further complicated patient diagnosis and treatment, and the distinction between real and induced demand 29 . It seems that the implementation of healthcare reform in Iran and significant reductions in patients’ out-of-pocket payments have resulted in increased demand for services. This issue is not observed in countries with more stable healthcare system. On the other hand, cultural differences and health beliefs affect the amount of demand in different regions. Induced demand occurs because of multiple economic and structural factors 22 . The present study found a significant relationship between induced demand and the related factors of knowledge and awareness of service recipients, sensitivity of clients toward their own health, monitoring and planning of insurance companies, personal interests of service providers, industrialization of the healthcare sector, increases in the variety and number of specialists, knowledge and awareness of service providers, quality of education models and training methods for service providers. Leone conducted a study in three provinces of India in 2014, which indicated the role of several factors in induced supply and demand 30 . The present study is also in line with a study by Keyvanara et al , which demonstrated factors such as the role of supplemental health insurance, lack of strict supervision on insurance companies, increased profit of equipment companies, diagnostic centers, pharmaceutical companies, the over-trusting of physicians, incorrect demands of patient from the physicians, lack of awareness, patients’ free access to physicians, patients’ willingness to make greater use of free services and franchising affect the incidence of induced demand 4 . Bazyar et al indicated inadequate supervision on the insurance system as the main cause of induced demand 31 . A study conducted in China reported that the high percentage of cesarean sections is due to the decision of pregnant women. However, the physicians’ impact on the increased demand for cesarean section cannot be ruled out 32 . This imbalance between clients and physicians' knowledge may result in the physicians’ tendency to provide questionable services 3 . A physician has the expertise and knowledge to have a dual role of a consultant and service provider for the patient 33 . Borhanzade claims that poor monitoring and control by insurance companies on the payment system leads to easier demand for excess services 34 . The findings of other studies indicate that consumers compensate for the increased costs of healthcare by using supplemental insurance 35 . Madden et al believe that different methods of payment affect the professional behavior of service providers 36 . According to a study by Dosoretz, physicians and other providers maximize their benefit when clinical values are not defined 37 . The difference between the results of this study and those of other studies is due to the focus of other studies on methods of payment to physicians and other components of health economics, whereas the present study emphasized more on social factors, knowledge, attitude, commitment to medical ethics and insurance company monitoring. Authorities and decision-makers in the healthcare sector should aim to increase public awareness about diseases and treatment processes, and offer appropriate solutions to increase physicians’ occupational commitment by changing the medical education system. In the meantime, other interfering factors in increased demand such as payment methods, performance of public and supplementary insurances should be monitored closely. In this regard, the mass media could be helpful in raising public awareness and modifying pubic beliefs. The present study showed that the industrialization of the healthcare sector and an increase in the variety and numbers of specialists are effective on induced demand. Nowadays, market competition has been created between the providers of healthcare services. Ferguson demonstrated that induced demand results from the increasing role of the market in medical care 38 . Economics is the most important factor affecting the medical institutions, which use induced demand as a means of increasing profits. An increase in unnecessary services leads to increased profit, and even distribution of money between various providers 39 . Bhatia emphasizes that the pharmaceutical market is highly competitive, and each company is constantly marketing to maximize their revenue 40 . Palesh et al claimed that market forces such as advertising are significantly effective on the unnecessary use of technology. Moreover, advertisements of importers and manufacturers increase demand 41 . However, Bickerdyke et al suggest that induced demand is influenced by the patient's goals (including good health, vitality, longevity, information, autonomy, usefulness of process, regular source of care, confidence, access to benefits of social security or insurance payments and pain relief), medical history and environmental factors (including financial situation, family/work commitments, cultural background and attitude of the society) 42 . Nevertheless, it seems that this previous study was patient-centered, and mostly focused on the quality of services rather than social and economic aspects. Practice implications Although healthcare services are the main indicator of social development, the provision of such services is tremendously costly. The ever-increasing cost, along with induced demand for services, causes certain problems in society. The results of this study showed that the phenomenon of induced demand is influenced by various factors, including the knowledge and awareness of service recipients, sensitivity of clients toward their own health, monitoring and planning of insurance companies, personal interests of service providers, industrialization of the healthcare sector, increases in the variety and number of specialists, knowledge and awareness of service providers, quality of education models and training methods for service providers. Therefore, it is suggested that decision makers and policymakers in the community arena can improve health services by increasing the quality of services and satisfaction of patients reducing direct payments from people, reducing household expenses, observing tariffs, lowering under-payment and unnecessary inductive demand.

Not approved - fundamental flaws in the paper seriously undermine the findings and conclusions Click here to access the data. The problem Spreadsheet data files may not format correctly if your computer is using different default delimiters (symbols used to separate values into separate cells) - a spreadsheet created in one region is sometimes misinterpreted by computers in other regions. You can change the regional settings on your computer so that the spreadsheet can be interpreted correctly. How to fix it Save downloaded CSV file Open spreadsheet program (e.g. Excel) Click the ‘Data’ tab at the top Click the ‘From text’ icon (top left) Browse for downloaded CSV file, click ‘Import’ Ensure ‘Delimited’ radio button is selected, click ‘Next’ Check one of the appropriate delimiter checkboxes (you can visualize the formatting by looking at the data preview below these options) Click ‘Finish’ Downloaded data do not display as expected?
