Valuing the SF-6Dv2 in the capital of Iran using a discrete choice experiment with duration.

BACKGROUND: The second version of the Short-Form 6-Dimension (SF-6Dv2) classification system has recently been developed. The objective of this study was to develop a value set for SF-6Dv2 based on the societal preferences of a general population in the capital of Iran. METHODS: A representative sample of the capital of Iran (n = 3061) was recruited using a stratified multistage quota sampling technique. Face-to-face interviews were conducted using binary choice sets from the international valuation protocol of the discrete choice experiment with duration. The conditional logit was used to estimate the final value set, and a latent class model was employed to assess heterogeneity of preferences. RESULTS: Coefficients generated from the models were logically consistent and significant. The best model was the one that included an additional interaction term for cases where one or more dimensions reached their most severe levels. It provides a value set with logical consistent coefficients and the lowest percentage of worse than death health states. Predicted values for the SF-6Dv2 were within the range of - 0.796-1. Pain dimension had the largest impact on utility decrement, whereas vitality had the least impact. The presence of preference heterogeneity was evident, and the Bayesian Information Criterion indicated the optimal fit for a latent class model with two classes. CONCLUSION: This study provided the SF-6Dv2 value set for application in the context of Iran. This value set will facilitate the use of the SF-6Dv2 instrument in health economic evaluations and clinical settings.

A national survey of Iranian general population to estimate a value set for the EQ-5D-5L.

OBJECTIVES: The main aim of this study is to estimate a national value set of the EQ-5D-5L questionnaire for Iran. METHODS: The composite time trade-off (cTTO) and discrete choice experiment (DCE) methods; and the protocol for EuroQol Portable Valuation Technology (EQ-PVT) were used to estimate the Iran national value set. 1179 face-to-face computer-assisted interviews were conducted with adults that were recruited from five Iran major cities in 2021. Generalized least squares, Tobit, heteroskedastic, logit, and hybrid models were used to analyze the data and to identify the best fitting model. RESULTS: According to the logical consistency of the parameters, significance levels and prediction accuracy indices of the MAE; a heteroscedastic censored Tobit hybrid model combining cTTO and DCE responses was considered as the best fitting model to estimate the final value set. The predicted values ranged from - 1.19 for the worst health state (55555) to 1 for full health (11111), with 53.6% of the predicted values being negative. Mobility was the most influential dimension on health state preference values. CONCLUSIONS: The present study estimated a national EQ-5D-5L value set for Iranian policy makers and researchers. The value set enables the EQ-5D-5L questionnaire to use to calculate QALYs to assist the priority setting and efficient allocation of limited healthcare resources.

Vaccination status of COVID-19 patients followed up in the ICU in a country with heterologous vaccination policy: A multicenter national study in Turkey.

OBJECTIVE: Vaccination against severe acute respiratory syndrome coronavirus-2 (SARS-2) prevents the development of serious diseases has been shown in many studies. However, the effect of vaccination on outcomes in COVID-19 patients requiring intensive care is not clear. METHODS: This is a retrospective multicenter study conducted in 17 intensive care unit (ICU) in Turkey between January 1, 2021, and December 31, 2021. Patients aged 18 years and older who were diagnosed with COVID-19 and followed in ICU were included in the study. Patients who have never been vaccinated and patients who have been vaccinated with a single dose were considered unvaccinated. Logistic regression models were fit for the two outcomes (28-day mortality and in-hospital mortality). RESULTS: A total of 2968 patients were included final analysis. The most of patients followed in the ICU during the study period were unvaccinated (58.5%). Vaccinated patients were older, had higher Charlson comorbidity index (CCI), and had higher APACHE-2 scores than unvaccinated patients. Risk for 28-day mortality and in-hospital mortality was similar in across the year both vaccinated and unvaccinated patients. However, risk for in-hospital mortality and 28-day mortality was higher in the unvaccinated patients in quarter 4 adjusted for gender and CCI (OR: 1.45, 95% CI: 1.06-1.99 and OR: 1.42, 95% CI: 1.03-1.96, respectively) compared to the vaccinated group. CONCLUSION: Despite effective vaccination, fully vaccinated patients may be admitted to ICU because of disease severity. Unvaccinated patients were younger and had fewer comorbid conditions. Unvaccinated patients have an increased risk of 28-day mortality when adjusted for gender and CCI.

The Clinical and Laboratory Efficacy of HA 330 Treatment Combined with Continuous Renal Replacement Therapy in Septic Shock Patients: A Case Series.

INTRODUCTION: Blood purification therapy is a method used to enable cytokine removal and to improve disturbed immune homeostasis in patients with sepsis or septic shock. This study aimed to evaluate the impact of HA 330 treatment on biochemical and hemodynamic parameters and cytokine levels in adult patients with septic shock. METHODS: Critically ill patients with septic shock who received continuous veno-venous hemodiafiltration and HA 330 treatment were included in this prospective observational study. Biochemical and hemodynamic parameters were followed throughout HA 330 treatment. Serum interleukin (IL)-1ß, IL-6, IL-8, tumor necrosis factor (TNF)-α, high-mobility group box1 (HMGB-1) protein, IL-10 levels were analyzed by ELISA method, before and after each HA 330 session. RESULTS: A total of 18 critically ill patients were included in this study. The median APACHE 2 score was 22.2 ± 7.49 and median SOFA score 9.6 ± 5.44 on intensive care unit admission. SOFA scores were significantly decreased on the 3rd day of HA 330 treatment, compared to 2nd day scores (p = 0.017). Median leukocyte value was significantly decreased (p = 0.027 and p = 0.024), while hemodynamic parameters remained unchanged throughout the HA 330 treatment. Median CRP and procalcitonin levels were significantly reduced at day 3 of HA 330 treatment compared to the baseline (p = 0.015 and p = 0.033, respectively). Serum IL-1 ß, IL-6, IL-8, TNF-a, HMGB-1, and IL-10 levels decreased insignificantly by 11.5%, 26.4%, 11.4%, 37.9%, 0.02%, and 35.5%, respectively, at the end of the hemoperfusion treatment compared to the pre-treatment. CONCLUSION: The administration of HA 330-based hemoperfusion in septic shock patients revealed improvements in SOFA scores, leukocyte count, and CRP and procalcitonin levels. However, there was no statistically significant change in concentrations of inflammatory cytokines and hemodynamic parameters during HA 330 treatment.

Is lifestyle modification with individual face-to-face education and counseling more effective than usual care for controlling hypertension? A systematic review and meta-analysis of randomized controlled trials.

Hypertension (HTN) management continues to be a concern due to challenges with behavioral risk factors. Patient education to modify unhealthy behaviors appears to be effective in managing HTN. Therefore, this meta-analysis aimed to determine whether individualized face-to-face education and counseling have a beneficial effect on systolic and diastolic blood pressure (SBP and DBP) in hypertensive patients. Studies were extracted from PubMed, Scopus, Cochrane Library, and Web of Science databases. Nine studies, comprising 2627 participants, were included. Random effects models were used to pool estimates of mean differences (MDs) with 95% confidence intervals (CIs) in SBP and DBP between the intervention and usual care groups. SBP and DBP were significantly reduced at the 6-month (MD = -4.38 mmHg, 95% CI: -6.95 to -1.81; MD = -2.09 mmHg, 95% CI: -3.69 to -0.50, respectively) and 12-month time points (MD = -2.48 mmHg, 95% CI: -3.96 to -1.01; MD = -1.71 mmHg, 95% CI: -2.88 to -0.55, respectively) with intervention. At the 24-month time point, there was a significant change in SBP (MD = -2.13 mmHg, 95% CI: -3.94 to -0.32) with intervention compared with the usual care group. This study showed that individualized face-to-face education and counseling add significant benefits to usual care for lowering blood pressure in hypertensive patients. Graphical Abstract.

Payment systems for dialysis and their effects: a scoping review.

BACKGROUND: End stage renal disease (ESRD) is a major health concern and a large drain on healthcare resources. A wide range of payment methods are used for management of ESRD. The main aim of this study is to identify current payment methods for dialysis and their effects. METHOD: In this scoping review Pubmed, Scopus, and Google Scholar were searched from 2000 until 2021 using appropriate search strategies. Retrieved articles were screened according to predefined inclusion criteria. Data about the study characteristics and study results were extracted by a pre-structured data extraction form; and were analyzed by a thematic analysis approach. RESULTS: Fifty-nine articles were included, the majority of them were published after 2011 (66%); all of them were from high and upper middle-income countries, especially USA (64% of papers). Fee for services, global budget, capitation (bundled) payments, and pay for performance (P4P) were the main reimbursement methods for dialysis centers; and FFS, salary, and capitation were the main methods to reimburse the nephrologists. Countries have usually used a combination of methods depending on their situations; and their methods have been further developed over time specially from the retrospective payment systems (RPS) towards the prospective payment systems (PPS) and pay for performance methods. The main effects of the RPS were undertreatment of unpaid and inexpensive services, and over treatment of payable services. The main effects of the PPS were cost saving, shifting the service cost outside the bundle, change in quality of care, risk of provider, and modality choice. CONCLUSION: This study provides useful insights about the current payment systems for dialysis and the effects of each payment system; that might be helpful for improving the quality and efficiency of healthcare.

Policy analysis of nutrition stewardship for prevention and control of Non-communicable diseases in Iran.

BACKGROUND: Non- communicable diseases (NCDs) are the main cause of death, which lead to over 73% of death and 62% of DALYs globally. As an unhealthy diet is the leading behavioral risk factor of NCDs, in line with the national action plan for the prevention and control of NCD, this study explored the nutrition-related stewardship problems to reduce the burden of NCDs in Iran. METHODS: This is a qualitative study. We interviewed 30 purposefully identified key informants, i.e., stakeholders, policymakers, and academics, from December 2018 to August 2019. All interviews were recorded and transcribed verbatim. We analyzed data using qualitative content analysis facilitated by MAXQDA 11 software. RESULTS: Ample policies and laws were identified, most of which were not or partially implemented. Despite some plausible efforts, NCDs do not seem to be a top priority for high-level managers and decision-makers. Besides, the role of non-state actors, i.e., the private sector, is marginal in NCD's planning and management. Whereas the government, e.g., the Food and Drug Organization (FDO), is the biggest player. Worse still, many harmful products are advertised and easily distributed across the country. CONCLUSION: Iran's government has created a noticeable roadmap to battle NCDs despite imposing many sanctions and related socioeconomic problems. Nevertheless, more interventions are needed to strengthen the stewardship of NCDs by various stakeholders. We recommend the government to monitor the implementation of policies and advertisement of harmful products to prioritize prevention and control of NCDs. In addition, we advocate employing the capacity of non-state actors to reduce the consumption of unhealthy food and the burden of NCDs across the country, ultimately.

Iranian medical students' tendency to migrate and its associated factors.

BACKGROUND: Medical staff migration is one of the challenges for both developed and developing countries affecting society's health and welfare, which limits access to equity. Therefore, this study was designed and conducted to investigate the tendency to migrate and the factors affecting it among medical students of the Tehran University of medical sciences, Tehran, Iran, in 2019. METHODS: This cross-sectional study was performed among 472 medical students using a valid questionnaire which was designed after reviewing the literature and using the opinions of experts. The tendency to migrate and its associated factors were analyzed and reported using the Pearson correlation test, independent t-test, one-way ANOVA test, Tukey post-hock test, and Kruskal-Wallis non-parametric test. RESULTS: According to this study, the tendency to migrate was 6.13 ± 2.82 out of 10. While there was no significant relationship between age, marital status, medical educational phase and the tendency to migrate (p > 0.05); There was a significant relationship between willingness to migrate with variables of gender (p = 0.027), pre-university study region (p < 0.001), father's academic degree (p = 0.007), mother's academic degree (p < 0.001), having the relative abroad (p < 0.001), foreign trip experience (p < 0.001), foreign language skills (p < 0.001), number of published articles (p = 0.005) and Iran's National Elite Foundation membership (p = 0.039). CONCLUSIONS: Females, elites, and those with higher socioeconomic state, previous exposure to foreign countries, the ability to speak foreign languages, and research activity are more likely to migrate. Considering the high tendency to migrate among Iranian medical students, urgent and severe strategies must be undertaken to solve this social and health problem.

A cost-effectiveness modeling study of treatment interventions for stage I to III esophageal squamous cell carcinoma.

BACKGROUND: Esophageal cancer causes considerable costs for health systems. Appropriate treatment options for patients with esophageal squamous cell carcinoma (ESCC) can reduce medical costs and provide more improved outcomes for health systems and patients. This study evaluates the cost-effectiveness of treatment interventions for patients with ESCC according to the Iranian health system. MATERIAL AND METHODS: A five-state Markov model with a 15-year time horizon was performed to evaluate the cost-effectiveness of treatment interventions based on stage for ESCC patients. Costs ($US 2021) and outcomes were calculated from the Iranian health system, with a discount rate of 3%. One-way sensitivity analyses were performed to assess the potential effects of uncertain variables on the model results. RESULTS: In stage I, the Endoscopic Mucosal Resection (EMR) treatment yielded the lowest total costs and highest total QALY for a total of $1473 per QALY, making it the dominant strategy compared with esophagectomy and EMR followed by ablation. In stages II and III, chemoradiotherapy (CRT) followed by surgery dominated esophagectomy. CRT followed by surgery was also cost-effective with an incremental cost-effectiveness ratio (ICER) of $2172.8 per QALY compared to CRT. CONCLUSION: From the Iranian health system's perspective, EMR was the dominant strategy versus esophagectomy and EMR followed by ablation for ESCC patients in stage I. The CRT followed by surgery was a cost-effective intervention compared to CRT and esophagectomy in stages II and III.

Health related quality of life in adults with asthma: a systematic review to identify the values of EQ-5D-5L instrument.

INTRODUCTION: The EQ-5D is the most popular generic preference-based instrument used for asthma patients. This study aims to explore the psychometric properties of the EQ-5D-5L instrument in patients with asthma and identify the EQ-5D-5L scores in these patients. METHOD: PubMed, Scopus, Web of Science, Google Scholar and CEA Registry were searched with English language from 2009 until April 2020. Retrieved studies were checked against the inclusion criteria. Reference lists of the included articles were also reviewed. The quality of included articles was evaluated using Mitton checklist and the data were extracted by a reviewer and were checked by a second reviewer. Meta-analysis was done to calculate the overall scores based on type of asthma control. RESULTS: A total of 17 articles were included. The EQ-5D-5L scores ranged from 0.45 to 0.93 and the VAS scores ranged from 35.67 to 83.80. The EQ-5D-5L is higher in well-controlled (0.88, 95% CI: 0.81-0.96, P = 0.0001) than partly controlled (0.80, 95% CI: 0.74-0.85, P = 0.001) and poorly controlled asthma (0.72, 95% CI: 0.67-0.77, P = 0.01). Validity in two studies was weak and, in other studies, it was moderate to strong. Responsiveness of the EQ-5D-5L, that was shown in a study, was less than other generic instruments, and reliability was adequate in only study that had been reported. Ceiling effects were between 8.30% to 35%. CONCLUSION: Higher score of the EQ-5D-5L was consistent with well-controlled asthma patients and those with lower severity of asthma. The assessment of psychometric properties of the EQ-5D-5L needs further observations.

Public preferences regarding the priority setting criteria of health interventions for budget allocation: results of a survey of Iranian adults.

OBJECTIVES: Priority setting in health directly impacts the general public as payers and final consumers, so the public preferences must be considered. The present study aimed to provide public preferences about health intervention allocation criteria for the optimal allocation of public health budget in Iran. METHODS: A choice-based survey method was used to assess the general public's preferences regarding 8 critical criteria with a societal aspect. One thousand sixty-four adult citizens of Tehran, Iran, participated in the study. Participants were asked to allocate a hypothetical budget between the two groups with differences in allocation criteria. Public preferences were inferred from absolute majority responses i.e., more than 50% of participants' allocation for a criterion. The Logistic Regression Model was used to investigate the factors affecting the preferences regarding the importance of allocation criteria. RESULTS: Based on expressed participants' preferences, criteria of disease severity, age, daily care needs, Number of alternative interventions, individual's economic status, and diseases with absence from work were important. Thus, 77, 69, 61, 57, 54, and 51% of participants preferred to allocate the hypothetical budget to the treatment of patients with poor economic status, treatment of patients with diseases leading to absence from work, treating patients with severe diseases, treatment of diseases in need of daily care and treatment of children's diseases, respectively. Findings from the factors affecting participants' preferences regarding allocation criteria also showed that people with different characteristics had different preferences. CONCLUSIONS: Iranian general public pays special attention to the criteria of equitable allocation, including patients' economic status, criteria with societal aspects such as absenteeism from work and the need for daily care, as well as criteria with medical aspects such as disease severity and access to alternative interventions which may sometimes be less considered in decision making.

The impact of social determinants of health on early childhood development: a qualitative context analysis in Iran.

BACKGROUND: Social determinants have a significant impact on children's development and their abilities and capacities, especially in early childhood. They can bring about inequity in living conditions of children and, as a result, lead to differences in various dimensions of development including the social, psychological, cognitive and emotional aspects. We aimed to identify and analyze the social determinants of Early Childhood Development (ECD) in Iran and provide policy implications to improve this social context. METHODS: In a qualitative study, data were collected through semi-structured interviews with 40 experts from October 2017 to June 2018. Based on Leichter's (1979) framework and using the deductive approach, two independent researchers conducted the data analysis. We used MAXQDA.11 software for data management. RESULTS: We identified challenges related to ECD context in the form of 8 themes and 22 subthemes in 4 analytical categories relevant to the social determinants of ECD including: Structural factors (economic factors: 6 subthemes, political factors: 2 subthemes), Socio-cultural factors (the socio-cultural setting of society: 6 subthemes, the socio-cultural setting of family: 4 subthemes), Environmental or International factors (the role of international organizations: 1 subtheme, political sanctions: 1 subtheme), and Situational factors (genetic factors: 1 subtheme, the phenomenon of air pollution: 1 subtheme). We could identify 24 policy recommendations to improve the existing ECD context from the interviews and literature. CONCLUSION: With regard to the challenges related to the social determinants of ECD, such as increasing social harms, decreasing social capital, lack of public awareness, increasing socio-economic inequities, economic instability, which can lead to the abuse and neglect of children or unfair differences in their growth and development, the following policy-making options are proposed: focusing on equity from early years in policies and programs, creating integration between policies and programs from different sectors, prioritizing children in the welfare umbrella, empowering families, raising community awareness, and expanding services and support for families, specially the deprived families subject to special subsidies.

Methods and criteria for the assessment of orphan drugs: a scoping review.

OBJECTIVES: This study aimed to identify different criteria for priority setting of rare diseases to help policy makers in making evidence-informed decisions. METHODS: A scoping review was conducted to comprehensively examine the existing various methods and criteria for prioritizing orphan drugs and rare diseases. We performed searching in Scopus, PubMed, Embase, and websites of health technology assessment (HTA) agencies, 2000-21, and data were extracted. RESULTS: From the 1,580 identified publications, eleven articles were included. Multicriteria decision analysis was the most frequent method (seven out of eleven studies) used for priority setting. The extracted criteria for priority setting of orphan products were analyzed based on six main categories as follows: health outcomes and clinical implications (six subsets which showed clinical implications), economic aspects (four subsets that indicated the economic effects of orphan drugs and rare diseases), disease and population characteristics (six subsets that included the characteristics of the rare diseases), therapeutic alternatives and uniqueness of orphan technologies (two subsets which discussed the alternatives and uniqueness of orphan technologies), evidence (three subsets which regarded the quality and availability of evidence), and other criteria (three subsets dealing with social and organizational criteria). Cost-effectiveness, budget impact, and disease severity were the most frequent criteria in the studies. CONCLUSIONS: Because of the high price of orphan drugs and limitations of using HTA for reimbursement of them, it is critical to explore them by precise technical methods like multiple criteria decision making in priority setting.

Responsiveness of hospitals to inpatient and outpatient services in the low- and middle-income countries: A systematic review.

Responsiveness is the ability of health system to satisfy non-clinical people's expectations. This review aimed at assessing responsiveness of hospitals' services in the low- and middle-income countries, and identifying the influencing factors. This systematic review followed the PRISMA guidelines. PubMed, Scopus, Web of Science and ProQuest were searched. Studies of all designs aiming to assess responsiveness of hospitals' services in the period from 2005 up to the end of 2018 were included. Quality was appraised based on McMaster University tool. Results were presented as a narrative review. Fifteen studies originated from five low-middle- income countries have been included. Results have been proposed under five subtopics; level and distribution of responsiveness and its domains at hospitals, rank of domains according to the participants, and factors affecting responsiveness and its related domains. Most studies have focused on responsiveness level, but not the distribution. Socioeconomic status, organisational, systemic, and contextual factors have led to varied responsiveness, consequently, policymakers would benefit from these valuable results while planning for improving health system in order to accomplish its intrinsic goals. Further research is required in the low- and middle-income countries other than the five included in this review. Using the World Health Organization questionnaires for measuring responsiveness is recommended, and the contextual variations should be considered.

Challenges of and corrective recommendations for healthcare-associated infection's case findings and reporting from local to national level in Iran: a qualitative study.

BACKGROUND: The accuracy of health care-associated infections (HAIs) statistics in many countries is questionable and the main reasons of this inaccuracy are not well-known. The study aim was to explore inhibitors of and corrective recommendations for HAIs case findings and reporting in some of Iran hospitals. METHODS: Sixteen face-to-face interviews and an expert panel were performed with expertise of infection prevention and control (IPC) programs in hospitals, and Deputies of Health and Treatment in medical university and Ministry of Health from Feb 2018 to May 2019. Using conventional content analysis, code, subcategories and categories were developed. RESULT: Three categories emerged including improper structure preparation, conflict of interest, and inadequate motivation. Allocating distinct budget and adequate staff to IPC programs, developing a user-friendly surveillance system and engaging physicians and nurses for HAIs reporting are the main corrective recommendations accepted by the expert panel. CONCLUSION: Despite the improvement in growing case-findings and reporting of HAIs in Iran, there are many challenges which inhibit accurate case finding and reporting of HAIs. So it is necessary to update the structure, system and rules to reach accurate HAIs data in Iran.

Adaptation Frameworks for Clinical Guidelines and Proposing a Framework for Iran: A Review and Comparative Study.

Background: Clinical Practice Guidelines (CPGs) can be adapted to local conditions to prevent any resources from being wasted. Adaptation of CPGs implies a systematic view of developed guidelines through maintaining evidence-based principles in order to find the ones most relevant with patients' conditions and its integration with the cultural and regional requirements of the target population and health system facilities. The main purpose of the study was to describe, interpret and compare different frameworks for adaptation of clinical guidelines and proposing a comprehensive framework for Iran. Methods: This study was based on a review and comparative analysis of adaptation frameworks of CPGs. Initially, all adaptation frameworks were collected by systematic search in the literature. We searched the following electronic databases: PubMed, Scopus, Trip Database, Science Direct, and Google Scholar. Then, based on the stages of the comparative study, frameworks were described, interpreted, juxtaposed, and compared. Finally, a comprehensive framework for the adaptation of clinical guidelines was proposed by consulting a panel of experts. Results: Our literature search resulted in 26 frameworks, of which 18 were potentially relevant. Based on inclusion/exclusion criteria, nine frameworks were included in the study and have been described, interpreted, and compared. The proposed comprehensive framework for the adaptation of clinical guidelines consists of ten main steps. Conclusion: The proposed comprehensive framework is an appropriate tool for the adaptation of clinical guidelines in Iran that can be used in other countries. However, further validation of the framework requires case studies and expert consultation to determine its application to the adaptation of clinical guidelines.

The economic burden of tuberculosis in Sistan: a high-risk region in Iran.

INTRODUCTION: To estimate the economic burden of tuberculosis treatment in Sistan, the region with the highest number of tuberculosis cases in Iran. METHODS: All patients with smear-positive pulmonary tuberculosis who had contracted tuberculosis in 2018 and successfully completed their treatment were interviewed. RESULTS: Ninety patients with a mean age of 57 ± 18 years were interviewed. Most of them were women (58%), housewives (57%) and resided in rural areas (84%). The mean cost of treatment for tuberculosis was estimated as 6800 USD per patient. Direct costs were 87% of the total cost. Twenty-two patients lost an average income of 530 USD (8514590 rials) during treatment. The results showed the significant correlation of direct and indirect costs with sex, age, place of residence and education (P < 0.05). CONCLUSION: It appears essential to improve social protection and implement interventions to promote knowledge in rural areas.

Cost per DALY averted in low, middle- and high-income countries: evidence from the global burden of disease study to estimate the cost-effectiveness thresholds.

BACKGROUND: Determining the cost-effectiveness thresholds for healthcare interventions has been a severe challenge for policymakers, especially in low- and middle-income countries. This study aimed to estimate the cost per disability-adjusted life-year (DALY) averted for countries with different levels of Human Development Index (HDI) and Gross Domestic Product (GDP). METHODS: The data about DALYs, per capita health expenditure (HE), HDI, and GDP per capita were extracted for 176 countries during the years 2000 to 2016. Then we examined the trends on these variables. Panel regression analysis was performed to explore the correlation between DALY and HE per capita. The results of the regression models were used to calculate the cost per DALY averted for each country. RESULTS: Age-standardized rate (ASR) DALY (DALY per 100,000 population) had a nonlinear inverse correlation with HE per capita and a linear inverse correlation with HDI. One percent increase in HE per capita was associated with an average of 0.28, 0.24, 0.18, and 0.27% decrease on the ASR DALY in low HDI, medium HDI, high HDI, and very high HDI countries, respectively. The estimated cost per DALY averted was $998, $6522, $23,782, and $69,499 in low HDI, medium HDI, high HDI, and very high HDI countries. On average, the cost per DALY averted was 0.34 times the GDP per capita in low HDI countries. While in medium HDI, high HDI, and very high HDI countries, it was 0.67, 1.22, and 1.46 times the GDP per capita, respectively. CONCLUSIONS: This study suggests that the cost-effectiveness thresholds might be less than a GDP per capita in low and medium HDI countries and between one and two GDP per capita in high and very high HDI countries.

The impact of common chronic conditions on health-related quality of life: a general population survey in Iran using EQ-5D-5L.

BACKGROUND: Diseases have undeniable effects on Health-Related Quality of Life (HRQoL). Chronic diseases, in particular, limit the productive potentials and HRQoL of individuals. EQ-5D is a very popular generic instrument, which can be used to estimate HRQoL scores in any diseases. The current study investigates mean HRQoL scores in certain chronic diseases and examines the relationship between utility scores and chronic diseases in Iran. METHOD: This cross-sectional study was carried out among the general adult population of Tehran. 3060 individuals were chosen by a stratified probability sampling method. The EQ-5D-5L questionnaire was applied. The utility scores were estimated using the Iranian crosswalk-based value set. The effect of chronic diseases on the HRQoL scores was derived by the Ordinary Least Squares (OLS) method. Data was analyzed using Stata version 13 software. RESULTS: The mean ± standard deviation utility and EQ-VAS scores were 0.85 ± 0.14 and 76.73 ± 16.55 in the participants without any chronic conditions. The scores were 0.69 ± 0.17 and 61.14 ± 20.61 in the participants with chronic conditions. The highest and lowest mean utility scores were related to thyroid disease (0.70) and Stroke (0.54), respectively. Common chronic conditions had significant negative effects on the HRQoL scores. Stroke (0.204) and cancer (0.177) caused the most reduction in the EQ-5D-5L utility scores. Lumbar disc hernia, digestive diseases, osteoarthritis, breathing problems, and anxiety/nerves cause 0.133, 0.109, 0.108, 0.087, and 0.078 reductions, respectively, in the EQ-5D-5L utility scores. CONCLUSION: This study provides insight into some common chronic conditions and their effects on the HRQoL. Policymakers and planners should pay attention to the effects of chronic conditions especially high prevalence one. They should adopt effective interventions to control this issue and increase health. The results of this study can also be beneficial in economic evaluation studies.

Application of discrete choice experiments to estimate value of life: a national study protocol in Iran.

BACKGROUND: Global concerns regarding the significant burden of non-communicable diseases and injuries (NCDIs) exist from both public health and economic perspectives. Our research focuses on the reduction of fatal risks due to NCDIs and the citizens' preferences about health programs and intervention to reduce premature death due to NCDIs. Governments and health authorities need reliable evidence and information to prioritize the interests of their citizens. One crucial piece of evidence to justify the resources spent on NCDIs is the value derived from the interventions on prevention and NCDIs control. This concept is usually called "Value of Statistical Life" (VSL), meaning the monetary value that individuals place on changes in the risk levels of life- threatening events. To the best of our knowledge, for the first time, our study will estimate the statistical value of life for selected interventions for the prevention and control of NCDIs at both national and sub-national levels in the context of Iran. This paper reports the development of a national protocol through Discrete Choice Experiments (DCEs) method. METHODS AND DESIGNS: Our study comprises several stages: (a) a literature review to identify the attributes and levels of the prevention programs and Willingness to Pay (WTP) for reducing the NCDI's fatal risks; (b) experimental design to assessing, prioritizing, and finalizing the identified attributes and levels; (c) instrumental design to conduct face-to-face structured survey interviews of 3180 respondents aged 18-69 across the entire country; (d) statistical analysis to estimate the results through the Mixed Multinomial logit (MMNL) model. DISCUSSION: We anticipate that our findings will help build a stronger empirical basis for monetizing the value of small changes in selected fatality risks. It paves the way for other national or vast VSL estimates for NCDIs, as well as other major causes of morbidity and mortality in the context of Iran, and perhaps other low and middle-income countries (LMICs).
