Research gaps identified in Iran's health technology assessment reports.

INTRODUCTION: Identifying gaps in the evidence is a useful byproduct of conducting a health technology assessment (HTA). This study aims to identify research gaps in Iran's HTA reports. METHOD: We reviewed the HTA reports published between 2014 and 2016. Then, we developed two separate questionnaires for principal investigators (PIs) and independent HTA researchers. The questionnaire for independent HTA researchers consisted of four main parts. However, the PIs' questionnaire consisted of two main parts. We also conducted a literature search in the PubMed database in November 2017 to find frameworks for prioritizing research gaps. We also conducted a semi-structured interview with the head of the Iran's HTA Office at that time and sought feedback based on his expert opinion about questionnaires, the priority-setting tool and our process for extracting research gaps. RESULTS: A total of 11 HTA reports published between 2014 and 2016 by Iran's HTA Office were selected for the study. Of these 11 reports, 5 involved technologies related to medical equipment, while 6 involved medical and surgical interventions. Assessing the outcomes of technology use in various indications and updating HTAs when new evidence arises; evaluating the viewpoints of patients, clinicians and key technology users; conducting post-marketing evaluations of technology; comparing the impact of the technology in question to other treatments for the same condition; and requesting long-term clinical and cost-effectiveness data for technologies with limited follow-up periods were identified as the main gaps by independent HTA researchers and PIs. CONCLUSIONS: The research gaps identified from Iran's HTAs could be utilized by research funding agencies.

Health Equity Impact Assessment (HEIA) reporting tool: developing a checklist for policymakers.

INTRODUCTION: Health Equity Impact Assessment (HEIA) is a decision support tool that shows users how a new program, policy, or innovation affects health equity in different population groups. Various HEIA reporting and dissemination tools are available, nevertheless, a practical standard tool to present the results of HEIA in an appropriate period to policymakers is lacking. This work reports the development of a tool (a checklist) for HEIA reporting at the decision-making level, aiming to promote the application of HEIA evidence for improving health equity. METHODS: This is a mixed-method study that was carried out over four stages in 2022-2023: 1) identifying HEIA models, checklists, and reporting instruments; 2) development of the initial HEIA reporting checklist; 3) checklist validation; and 4) piloting the checklist. We also analyzed the Face, CVR, and CVI validity of the tool. RESULTS: We developed the initial checklist through analysis of 53 included studies and the opinions of experts. The final checklist comprised five sections: policy introduction (eight subsections), managing the HEIA of policy (seven subsections), scope of the affected population (three subsections), HEIA results (seven subsections), and recommendations (three subsections). CONCLUSION: Needs assessment, monitoring during implementation, health impact assessment, and other tools such as monitoring outcome reports, appraisals, and checklists are all methods for assessing health equity impact. Other equity-focused indicators, such as the equity lens and equity appraisal, may have slightly different goals than the HEIA. Similarly, the formats for presenting and publishing HEIA reports might vary, depending on the target population and the importance of the report.

Reasons for informal payments from the perspective of health care providers and recipients: a qualitative study in Iran.

BACKGROUND: Informal payments are one of the major obstacles to health system reform in many developing countries, and its elimination is on the agenda of health system policymakers in many countries, including Iran. This study was conducted to identify the causes of informal payments in the Iranian health system. METHODS: This was a qualitative and exploratory study. The study environment included the Ministry of Health, physicians' offices, medical universities, and hospitals and health centers. The study population included health care providers (physicians and hospital staff, managers, supervisors, and nurses) and health care recipients (patients or patients who had a history of dealing with informal payments). Data were collected using open-ended questions and semi-structured interviews. Snowball sampling method was used to select managers, chief executive officers (CEOs) and nurses. Convenience sampling was used to select physicians due to their lack of participation and cooperation. Content analysis method was used to analyze the data. RESULTS: Reasons for informal payments were divided into 4 themes including: Economic factors (improper tariff valuation of services; failure to increase tariffs proportionate to inflation; lack of comprehensive participation of stakeholders in determining tariffs; tariff inconsistency in the public, private and charity sectors; etc.); socio-cultural factors (decreased social capital of the medical community among the people; improving the quality of life; incorrect comparison of providers' income levels with the income of doctors in other countries; existence of a culture of gratitude and appreciation; health as a priority for society; pride of service recipients; pride of service providers; etc.); service delivery challenges (high professional skills of the doctor; use of modern medical equipment; the monopoly of some doctors, etc.) and legal-political factors (inadequate monitoring by upstream organizations; lack of strict rules; difficulty of proving informal payments; presence of stakeholders in management and policy making processes). CONCLUSIONS: Knowing the causes of informal payments can help reduce or eliminate it. The results of this study identified the causes of informal payments in the Iranian health system. Accurate knowledge of the needs and motivations of both health care providers and recipients can be effective in accurately identifying and eliminating this phenomenon.

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.

Trauma Registry Data as a Policy-Making Tool: A Systematic Review on the Research Dimensions.

Objective: To review the research dimensions of trauma registry data on health policy making. Methods: PubMed and EMBASE were searched until July 2020. Keywords were used on the search process included Trauma, Injury, Registry and Research, which were searched by using appropriate search strategies. The included articles had to: 1. be extracted from data related to trauma registries; 2- be written in English; 3- define a time period and a patient population; 4- preferably have more details and policy recommendations; and 5- preferably have a discussion on how to improve diagnosis and treatment. The results obtained from the included studies were qualitatively analyzed using thematic synthesis and comparative tables. Results: In the primary round of search, 19559 studies were retrieved. According to PRISMA statement and also performing quality appraisal process, 30 studies were included in the final phase of analysis. In the final papers' synthesis, 14 main research domains were extracted and classified in terms of the policy implication and research priority. The domains with the highest frequency were "The relationship between trauma registry data and hospital care protocols for trauma patients" and "The causes of Disability Adjusted Life Years (DALYs) due to trauma". Conclusion: Using trauma registry data as a tool for policy-making could be helpful in several ways, namely increasing the quality of patient care, preventing injuries and decreasing their number, figuring out the details of socioeconomic status effects, and improving the quality of researches in practical ways. Also, follow-up of patients after trauma surgery as one of the positive effects of the trauma registry can be the focus of attention of policy-making bodies.

Knowledge gaps and national research priorities for COVID-19 in Iran.

BACKGROUND: In the present COVID-19 crisis, one of the greatest challenges for research funding at both the international and national level is selecting the best research topic to achieve efficiency and equity in health research and to address the knowledge gap urgently raised due to the event. Despite international recommendations, countries should consider their context-specific situation and define local research priorities. We aimed to exercise a priority-setting activity to identify the knowledge gaps and suggest research priorities in response to the COVID-19 epidemic in Iran. METHODS: First, we tried to identify the contextual knowledge gaps based on an online survey, performing key informant interviews (i.e. health professionals, policy-makers and managers) and media analysis. We also performed a literature review and considered international research priorities for COVID-19. Subsequently, we prepared a list of research questions and challenges to respond to the COVID-19 crisis in Iran using a systems approach. Then we mapped approved COVID-19 research projects in the country to research questions. Finally, we compared the identified research questions (not challenges) with the prioritized research from international organizations and then prioritized them for Iran. RESULTS: We found risk factors and epidemiological dissemination patterns of the virus and its consequences in an epidemiology domain, implementation of clinical and hygiene in a clinical management domain, genetic studies for targeting prevention and treatment in a candidate treatment and vaccine research and development (R&D) knowledge domain, examination of the manifestations of ethics in society instead of ethics in research in an ethics domain, "care, access and health system" and "public health and participation in response to public health and clinical research" as two sub-domains of a social sciences domain, and finally, no new questions in either the virology, transmission, diagnosis or animal and environmental domain. CONCLUSIONS: In the event of global health crises like COVID-19, prioritization of research questions can be done globally, but some of the research priorities are context-specific and may vary by regional needs. To better manage research resources, researchers must respond to the challenges faced in each country based on its political, economic, social and cultural characteristics, and to make evidence-informed decisions, global knowledge gaps must be customized in each country.

Topic selection for health technology assessment: An approach combining multiple attribute decision making and decision rules.

Background: Various studies have used multiple attribute decision making (MADM) techniques to assess and rank health technologies. The goal of the present study was to prioritize health technologies using various techniques of MADMs in combination with decision rules. Methods: The study is an applied research using multi-attribute decision making (MADM) methods. This study extracted the attributes related to health technology assessment from global literature and experts' opinions. In this study, two different types of experts were consulted: the first type, including three experts in the field of the decision-making techniques, on the subject of setting priority on health focusing on MADM; and the second one consists of seven experts in the field of HTA, asked about the selection of attributes and determination their importance. Candidate health technologies were individually weighted and ranked using TOPSIS, SAW and VIKOR by the weight and decision matrix. The results obtained from various techniques were combined and ranked using Copeland's technique to obtain the final ranking of health technologies. To determine HTA type reports, decision rules were defined. All models were designed via MS Excel. Results: This study chose eight technologies according to six tradeoff attributes. These attributes included health benefits at the population level, vulnerable population size, availability of alternative technologies, budget impact, financial protection, and quality of evidence. Their exact weights were 0.25, 0.121, 0.146, 0.132, 0.167 and 0.181, respectively. Also, safety and uncertainty about the cost-effectiveness were considered as the veto and decision rules respectively. Copeland's method was therefore used to combine the methods: Whereas HT2 (The technology for treating patients suffering from varicose) was ranked the highest priority and HT3 (The palliative method for patients who suffer from various cancers) was ranked the lowest (for preventing from any ethical issue, the exact name of each technology wasn't mentioned). Conclusion: Finally, in accordance with decision rules which are based on various conditions of "uncertainty about the cost-effectiveness", it is recommended that full health technology assessment report be performed on three technologies, rapid health technology assessment report be performed on four others, and, finally no prioritizing for health technology assessment be made on one of them.

Measuring Public Preferences for Changes in the Health Insurance Benefit Package Policies in Iran: A Survey Approach.

BACKGROUND: This study aimed to identify the public preference in health services, the principles that Iranian people consider important, and the aspects of tradeoffs between different values in resource allocation practices. METHODS: This quantitative study was conducted to investigate public preferences on Health Insurance Benefit Package (HIBP) in 2017. A structured questionnaire was used for data collection, including the preferences of the people who live in Tehran, were above 18 year, and were covered by basic insurance for the HIBP contents and premium. The sample size was calculated 430 subjects and SPSS Statistics was used for data analyzing. RESULTS: 81.6% of the sample population agreed with government allocating more money to the health sector compared to other sectors and organizations and 55% were willing to pay higher premiums for expanding the HIBP coverage. The highest and lowest score regarding prioritization of budget allocation between health services was related to hospitalization services (28.6%) and rehabilitation services (1.6%), respectively. The first priority of respondents regarding health care and life cycle, was "prevention in newborns" (15.9%), the second priority was "prevention in children" (14.6%), the third priority was "prevention in adults" (9.5%), and the last priority was "short-term care in newborns" (0.9%). CONCLUSION: Iranian people believe that not only the principle of health maximization but also equal opportunities to access health care and a fair allocation of resources should be considered by authorities for effective health insurance policymaking. In this case, given the scarcity of resources, setting priorities for alternative resources is inevitable.

Prioritizing the Potential Applications of Mobile-Health in the Iranian Health System.

BACKGROUND: Access and the use of information and communication technology, especially mobile phones, have expanded significantly in recent years; therefore, we aimed to rank the potential applications of mobile apps in the Iranian health system. STUDY DESIGN: A multi-attribute decision making design. METHODS: First, the main applications of apps and also the related attributes for prioritization were extracted from a systematic and comparative review of studies. Then, the weight of these attributes was extracted using the Shannon Entropy method. The values of attributes for each application were questioned by the 11 experts. By having the decision matrix and the weight of attributes, the applications were separately weighted and ranked using four MADM techniques. Finally, using the Copeland technique, the results of different techniques were combined, and a final ranking was achieved. RESULTS: Based on the results extracted from the studies and the opinions of experts, 8 main applications, and, 14 attributes were determined and entered into the modeling phase. The most significant weight obtained was related to "the feasibility of monitoring activities" (weight=0.220), and the least was related to "the feasibility of access to apps in any location" (weight=0.017). CONCLUSION: The apps related to the physicians' access to patients' health information had the highest priority, and the apps related to the selection of proper health behavior patterns had the least priority.

Assessment of remote patient monitoring (RPM) systems for patients with type 2 diabetes: a systematic review and meta-analysis.

INTRODUCTION: The objective of this study is to conduct an assessment of Remote Patient Monitoring (RPM) systems compared to usual care for controlling glycosylated hemoglobin in type 2 diabetes. METHODS: The study was a systematic review with meta-analysis and meta-regression. A systematic search was performed via the most important electronic databases of medical resources, such as PubMed, Scopus and Cochrane library. The main outcome was HbA1C. The heterogeneity sources were examined using Chi-square (Q) and I2 tests. Meta-analyses were done using Stata version 11 software. Statistical significance was defined as P < 0.05. Random effects model was used in meta-analysis, and the heterogeneity more than 50% was considered as significant. RESULTS: The results of the systematic review and meta-analysis indicated that the effect size index (Difference of Pre-test/Post-test Control Design-2nd method "using pooled pretest SD" (DPPC2)) among users of RPM for type 2 diabetic patients was -0.32 with a confidence interval of 95% (from -0.45 to -0.19) as compared to the control group. The current study declared a vital role of RPM technology in reduction of hemoglobin glycogen levels. The results of the subgroup analysis showed that RPM is more effective for patients who are residents of cities, having intervention lengths less than 6 months, getting the orders from the physician and using the websites as their intervention type. CONCLUSION: The current study indicted the efficacy of RPM in reducing HbA1c among type 2 diabetic patients, which could be a base for policymakers to decide on the introduction of this technology in Iran.

Decomposing inequality in financial protection situation in Iran after implementing the health reform plan: What does the evidence show based on national survey of households' budget?

BACKGROUND: Lack of well-designed healthcare financing mechanisms and high level of out-of-pocket payments in Iran over the last decades led to implementing Health Transformation Plan, in 2014. This study aims to decompose inequality in financial protection of Iranian households after the implementation of the Health Transformation Plan. METHODS: The data of Statistical Center of Iran (SCI) Survey on Rural and Urban Households Income-Expenditure in 2015 to 2016 were used. The headcount ratio of catastrophic health expenditures was calculated. The corrected concentration index was estimated. The role of contributors on inequality in the exposure to catastrophic health expenditures among poor and nonpoor households was calculated using Farelie's model. RESULTS: The headcount ratio of the exposure to catastrophic health expenditures in urban and rural households was 2.5% (2.43% - 2.64%) and 3.6% (3.48% - 3.76%), respectively. The difference in households' income levels was the main contributor in explaining the inequality in facing catastrophic health expenditures between poor and nonpoor households. [Correction added on 02 June 2018, after first online publication: The "Results" section of the Abstract of the published article has been correctly updated on this version.] CONCLUSION: Even after implementing the HTP, the headcount ratios of catastrophic health expenditure are still considerable. The results show that income is the greatest determinant of inequality in facing catastrophic health expenditure and in urban households.

Has the Financial Protection Been Materialized in Iranian Health System? Analyzing Household Income and Expenditure Survey 2003-2014.

BACKGROUND: The financial protection against catastrophic and impoverishing health expenditures is one of the main aspects of the universal health coverage. This study aimed to present a clear picture of the financial protection situation in Iran from 2003-2014. STUDY DESIGN: This is an analytical study on secondary data of Statistical Center of Iran (SCI). The study has some policy implications for policy makers; therefore, it is an applied one. METHODS: Data related to the Iranian rural and urban household payments on health expenditures was obtained from annual surveys of the SCI. WHO researchers' approach was used to calculate the Fairness of Financial Contribution Indicator (FFCI), the headcount and overshoot ratios of catastrophic and impoverishing health expenditures. A logistic regression was conducted to identify the determinants of probability of occurrence of catastrophic health expenditure among Iranian households in 2014. RESULTS: The mean of FFCI for rural and urban households was 0.854 (0.41) and 0.867 (0.32), respectively. The average headcount ratios of catastrophic and impoverishing health expenditures were 1.32% (0.24) and 0.33% (P=0.006) for rural households and 1.4% (0.6) and 0.28% (P=0.001) for urban households. Concerning rural households, the overshoot of catastrophic and impoverishing health expenditures was 14.94% (P=0.001) and 7.22% (0.53); it was 15.59% (1.54) and 7.76% (0.52) for urban households. CONCLUSIONS: No significant and considerable change was found in the headcount ratios of catastrophic and impoverishing health expenditure and in their overshoot or gap amounts. This suggested a lack of well-designed and effective schemes for materializing the financial protection in Iran.

Telemedicine: A systematic review of economic evaluations.

Background: Telemedicine is an expanded term in health information technology that comprises procedures for transmitting medical information electronically to improve patients' health status. The objective of this research is to evaluate the cost-effectiveness of telemedicine interventions in various specialty areas. Methods: The Cochrane Library and Centre for Review and Dissemination were searched up to February 2013 using Mesh. Studies that compared any kind of telemedicine with any other routine care technique and used cost per health utility unit's outcomes were included. Results: Twenty-one articles were included. According to the included studies, it seems that using telemedicine in cardiology can be effective and cost-effective enough but pre-hospital telemedicine diagnostics program are likely to have little impact on acute myocardial infarction fatality. In pulmonary, telemedicine can be a cost-effective strategy for delivering outpatient pulmonary care to rural populations which have limited access to specialized services, but telemedicine is not cost- effective in asthma and airways cancer. In ophthalmology, especially in the diagnosis of diabetic retinopathy, the use of telemedicine is a cost-effective tool. In dermatology, telemedicine is not cost-effective enough in comparison of conventional cares. In other fields such as physical activity and diet, eating disorder, tele-ICU, psychotherapy for depression and telemedicine on ships, telemedicine can be used as a cost-effective tool for treatments or cares. Conclusion: Most of the included studies confirmed that telemedicine is cost-effective for applying in major medical fields such as cardiology; but in dermatology, papers could not confirm the positive capability of telemedicine.

Health technology assessment of magnet therapy for relieving pain.

Background: Magnet therapy has been used increasingly as a new method to alleviate pain. Magnetic products are marketed with claims of effectiveness for reducing pain of various origins. However, there are inconsistent results from a limited number of randomized controlled trials (RCTs) testing the analgesic efficacy of magnet therapy. This study aimed to evaluate the safety and effectiveness of magnet therapy on reliving various types of pain. Methods: A systematic search of two main medical databases (Cochrane Library and Ovid Medline) was conducted from 1946 to May 2014. Only English systematic reviews that compared magnet therapy with other conventional treatments in patients with local pain in terms of pain relieving measures were included. The results of the included studies were thematically synthesized. Results: Eight studies were included. Magnet therapy could be used to alleviate pain of various origins including pain in various organs, arthritis, myofascial muscle pain, lower limb muscle cramps, carpal tunnel syndrome and pelvic pain. Results showed that the effectiveness of magnetic therapy was only approved in muscle pains, but its effectiveness in other indications and its application as a complementary treatment have not been established. Conclusion: According to the results, it seems that magnet therapy could not be an effective treatment for relieving different types of pain. Our results highlighted the need for further investigations to be done in order to support any recommendations about this technology.

Cost-effectiveness of teriparatide compared with alendronate and risedronate for the treatment of postmenopausal osteoporosis patients in Iran.

Background: Hip, vertebral and wrist fractures are the most common consequences of osteoporosis. This study aimed at analyzing the cost-effectiveness of teriparatide (CinnoPar®), compared with alendronate and risedronate, in the treatment of women aged 60 and over with postmenopausal osteoporosis in Iran. Methods: A decision tree model with a 2-year time horizon was used to compare treatment with teriparatide (CinnoPar®) with the following treatment strategies: two years of treatment with alendronate and two years of treatment with risedronate in women aged 60 years and over or those at risk of osteoporosis. Cost per QALY was calculated for 3 treatment strategies from the model. After base case analysis, one-way sensitivity analysis was performed on key parameters of the model to assess their impact on the study results and the cost-effectiveness of different treatment strategies and the model robustness. TreeAge Pro 2006 software was used for modeling and data analysis. Results: Incremental cost-effectiveness ratio (ICER) of alendronate and teriparatide than risedronate (base treatment) were US$- 2178.03 and US$483,783.67 per QALY, respectively. Therefore, the dominant and cost-effective treatment option was alendronate. In the one-way sensitivity analysis, the impact of annual 25% increase or decrease in the teriparatide cost on its ICER was remarkable. Also, reducing the discount rate from 0.03 to 0.0 had the greatest impact on the ICER of the teriparatide. Conclusion: The treatment strategy of teriparatide is more expensive than risedronate and alendronate and is associated with very little increase in QALYs. A significant reduction in teriparatide price and a limit in its use only for high-risk women and for acute and short-term treatment courses can contribute to its cost-effectiveness.

Comparison of the Joel-Cohen-based technique and the transverse Pfannenstiel for caesarean section for safety and effectiveness: A systematic review and meta-analysis.

Background: Caesarean section (C-section) is the most common surgery among women worldwide, and the global rate of this surgical procedure has been continuously rising. Hence, it is significantly crucial to develop and apply highly effective and safe caesarean section techniques. In this review study, we aimed at assessing the safety and effectiveness of the Joel-Cohen-based technique and comparing the results with the transverse Pfannenstiel incision for C-section. Methods: In this study, various reliable databases such as the PubMed Central, COCHRANE, DARE, and Ovid MEDLINE were targeted. Reviews, systematic reviews, and randomized clinical trial studies comparing the Joel-Cohen-based technique and the transverse Pfannenstiel incision were selected based on the inclusion criteria. Selected studies were checked by 2 independent reviewers based on the inclusion criteria, and the quality of these studies was assessed. Then, their data were extracted and analyzed. Results: Five randomized clinical trial studies met the inclusion criteria. According to the exiting evidence, statistical results of the Joel-Cohen-based technique showed that this technique is more effective compared to the transverse Pfannenstiel incision. Metaanalysis results of the 3 outcomes were as follow: operation time (5 trials, 764 women; WMD -9.78; 95% CI:-14.49-5.07 minutes, p<0.001), blood loss (3 trials, 309 women; WMD -53.23ml; 95% -CI: 90.20-16.26 ml, p= 0.004), and post-operative hospital stay (3 trials, 453 women; WMD -.69 day; 95% CI: 1.4-0.03 day, p<0.001). Statistical results revealed a significant difference between the 2 techniques. Conclusion: According to the literature, despite having a number of side effects, the Joel-Cohen-based technique is generally more effective than the Pfannenstiel incision technique. In addition, it was recommended that the Joel-Cohen-based technique be used as a replacement for the Pfannenstiel incision technique according to the surgeons' preferences and the patients' conditions.

Health technology assessment of image-guided radiotherapy (IGRT): A systematic review of current evidence.

BACKGROUND: Image-guided radiotherapy used multiple imaging during the radiation therapy course to improve the precision and accuracy of health care provider's treatment. OBJECTIVES: This study aims to assess the safety, effectiveness and economic aspects of image-guided radiation therapy for decision-making about this technology in Iran. METHODS: In this study, the most important medical databases such as PubMed and Cochrane Library were searched until November 2014. The systematic reviews, health technology assessment reports and economic evaluation studies were included. The results of included studies were analyzed via the thematic synthesis. RESULTS: Seven articles were included in the study. The results showed that image-guided radiation therapy, regardless of the imaging technique used in it, is associated with no major toxicity and has the potential to reduce the symptoms of poisoning. Using image-guided radiation therapy for prostate cancer resulted in substantial improvement in the quality of the received dose and optimal therapeutic dose of radiation to the targeted tumor while the radiation dose to the surrounding healthy tissues was minimal. Additionally, image-guided radiation therapy facilitated the diagnosis and management of exception deviations, including immediate changes and gross errors, weight loss, significant limbs deformity, systematic changes in the internal organs and changes in respiratory movements. Usage of image-guided radiation therapy for prostate cancer was associated with increased costs. CONCLUSION: Current available evidence suggests that the image-guided radiation therapy can reduce the amount of radiation to healthy tissue around the tumor and the toxicity associated with it. This can enhance the safe dose of radiation to the tumor and increase the likelihood of destruction of tumor. The current level of evidence required conducting further studies on the costs and effectiveness of this technology compared with conventional technology.

Safety, effectiveness and economic aspects of maggot debridement therapy for wound healing.

BACKGROUND: Maggot therapy has recently attracted considerable attention as an emerging debridement technique for wound healing. This study aimed to review the safety, effectiveness and economic evaluations of Maggot Debridement Therapy for wound healing. METHODS: To retrieve the relevant evidences, the Cochrane Library (until September 2014) was searched by appropriate keywords, using free text and Mesh. Systematic reviews, HTA reports and economic evaluation studies that compared larval therapy with other debridement therapies, such as hydrogel in patients with various kinds of ulcers in terms of side effects, the wound healing rate, the healing time, and cost per QALY, were included. RESULTS: Five studies met the inclusion criteria which showed that healing with larval therapy happened a little earlier than the usual methods and that pain perception in larval therapy was a little more than usual methods (as by anesthetic conventional methods). However, the quality of life of those patients who received larval therapy was better and they showed a greater tendency to larval therapy as it was relatively safe and had a low rate of side effects. CONCLUSION: It seems that larval therapy has several advantages such as rapid wound debridement, infection elimination, pain control and ulcer healing. The use of larval therapy has the potential to reduce side effects and decrease the need for amputation.

The health systems' priority setting criteria for selecting health technologies: A systematic review of the current evidence.

BACKGROUND: In the recent years, using health technologies to diagnose and treat diseases has had a considerable and accelerated growth. The proper use of these technologies may considerably help in the diagnosis and treatment of different diseases. On the other hand, unlimited and unrestricted entry of these technologies may result in induced demand by service providers. The aim of this study was to determine the appropriate criteria used in health technologies priority-setting models in the world. METHODS: Using MESH and free text, we sought and retrieved the relevant articles from the most appropriate medical databases (the Cochrane Library, PubMed and Scopus) through three separate search strategies up to March 2015. The inclusion criteria were as follows: 1) Studies with specific criteria; 2) Articles written in English; 3) Those articles conducted in compliance with priority setting of health technologies. Data were analyzed qualitatively using a thematic synthesis technique. RESULTS: After screening the retrieved papers via PRISMA framework, from the 7,012 papers, 40 studies were included in the final phase. Criteria for selecting health technologies (in pre assessment and in the assessment phase) were categorized into six main themes: 1) Health outcomes; 2) Disease and target population; 3) Technology alternatives; 4) Economic aspects; 5) Evidence; 6) and other factors. "Health effects/benefits" had the maximum frequency in health outcomes (8 studies); "disease severity" had the maximum frequency in disease and target population (12 studies); "the number of alternatives" had the maximum frequency in alternatives (2 studies); "cost-effectiveness" had the maximum frequency in economic aspects (15 studies); "quality of evidence" had the maximum frequency in evidence (4 studies); and "issues concerning the health system" had the maximum frequency in other factors (10 studies). CONCLUSION: The results revealed an increase in the number of studies on health technologies priority setting around the world, and emphasized the necessity of application of a multi- criteria approach for appropriate decision making about healthcare technologies in the health systems.

The safety and effectiveness of the current treatment regimen with or without roflumilast in advanced COPD patients: A systematic review and meta-analysis of randomized controlled trials.

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a chronic respiratory disease, which reduces the lung function and causes respiratory symptoms over time, and it is primarily associated with shortness of breath, cough and sputum production. Roflumilast, which is a long-acting selective inhibitor, reduces the anti-inflammatory effect of the main symptoms of COPD. The aim of this study was to compare the clinical effectiveness of adding roflumilast to the current treatment regimen of patients with severe COPD. METHODS: To retrieve the marker studies, medical databases were searched up to February 2014. We included studies, which compared the clinical effectiveness and safety of roflumilast as concomitant to Long-acting ß2-agonist/Long-acting muscarinic antagonist (LABA/LAMA) regimen, in adult patients with severe COPD. The number of exacerbations, changes in the lung function FEV1, FEV1/FVC and quality of life were the major predefined outcomes. Meta-analysis of outcomes was performed by the RevMan software, with I(2)> 50%, representing considerable heterogeneity. RESULTS: Seven randomized controlled trials and two systematic reviews were included. In terms of safety, participants were likely to experience more side effects from roflumilast compared to placebo, particularly gastrointestinal effects (diarrhea, nausea, vomiting), headache and weight loss. There was no significant difference in the risk of cardiac complications or flu-like symptoms or upper respiratory tract infection in the two groups. In terms of effectiveness, only a small improvement was observed in SGRQ (St George's Respiratory Questionnaire) index. Roflumilast reduced moderate to severe attacks, and caused significant improvements in the lung function regardless of the severity of the disease and the concurrent use of other standard COPD therapies. CONCLUSION: Roflumilast anti-inflammatory therapy reduces the chronic bronchitis symptoms in patients with moderate to severe COPD, and it can be safely used with other drugs simultaneously.
