Introduction Economic evaluation studies demonstrate the value of money in health interventions and enhance the efficiency of the healthcare system. Therefore, this study reviews published economic evaluation studies of public health interventions from 26 Middle East and North Africa (MENA) countries and examines whether they addressed the region's major health problems. Methods PubMed and Scopus were utilized to search for relevant articles published up to June 26, 2021. The reviewers independently selected studies, extracted data, and assessed the quality of studies using the Consolidated Health Economic Evaluation Reporting Standards (CHEERS) checklist. Results The search identified 61 studies. Approximately half (28 studies; 46%) were conducted in Israel and Iran. The main areas of interest for economic evaluation studies were infectious diseases (21 studies; 34%), cancers (13 studies; 21%), and genetic disorders (nine studies; 15%). Five (8%), 39 (64%), 16 (26%), and one (2%) studies were classified as excellent, high, average, and poor quality, respectively. The mean of CHEERS checklist items reported was 80.8% (SD 14%). Reporting the structure and justification of the selected model was missed in 21 studies (37%), while price and conversion rates and the analytical methods were missed in 21 studies (34%). Conclusions The quantity of economic evaluation studies on public health interventions in the MENA region remains low; however, the overall quality is high to excellent. There were obvious geographic gaps across countries regarding the number and quality of studies and gaps within countries concerning disease prioritization. The observed research output, however, did not reflect current and upcoming disease burden and risk factors trends in the MENA region.

Background: Tobacco smoking is a leading cause of premature mortality, incurring substantial economic costs. Aims: To estimate the rate and cost of premature mortality attributable to smoking in the 24 Middle East and North Africa (MENA) countries in 2015. Methods: Smoking attributable fractions were estimated. Twenty-four smoking-related diseases were included in the analysis. For each country, the total number of deaths by disease, age, and gender among individuals aged ≥ 15 years were derived from a World Health Organization database. Human capital approach was used in calculating cost of premature mortality. Results: Smoking was responsible for 465 285 deaths in MENA countries, resulting in 7 122 706 years of potential life lost, or an average of 15.23 years lost per smoking-related death. Of the total 465 285 smoking-related deaths, 412 415 (88.6%) occurred in men, accounting for 37% of all deaths from the diseases considered in this analysis among men. The total mortality cost attributable to smoking was estimated at US$ 29.7 billion in 2015 (0.76% of MENA’s gross domestic product). Turkey was the country most affected by the tobacco epidemic, representing 41% of smoking-related mortality cost in the whole region, followed by Saudi Arabia (8.76%) and Egypt (7.88%). Conclusion: Smoking is an important preventable cause of premature mortality in MENA countries. Substantial decline in smoking-attributable deaths and significant economic cost saving can be achieved in this region through more effective tobacco control policies.
