    Benchmarking countries' technical efficiency using AHP-based weighted slack-based measurement (W-SBM): A cross-national perspective
    (Elsevier Sci Ltd, 2023) Yetim, Birol; Sönmez, Seda; Konca, Murat; İlgün, Gülnur
    Objectives: The objective of the research is to assess the technical efficiency of national health systems in OECD member countries and to provide ideas to improve the efficiency of health systems in countries that have been identified as having a lower degree of efficiency as a result of the findings.Methods: The technical efficiency scores were calculated using one of the data envelopment analyses (DEA), the Weighted Slack-Based Measure (W-SBM). The Analytic Hierarchy Process was used to establish the aforementioned weights (AHP). Weights are calculated separately for both input and output variables.Results: The technical efficiency of the relevant countries' health systems is around 0.79, according to the data, and just 13 (36.1%) of the 36 countries have a fairly efficient health system.Conclusions: The outcomes of the study were supposed to aid health policymakers and management in improving system efficiency. In addition, since the number of studies examining the health systems of OECD countries with the W-SBM method is limited, it is thought that this study will make an important contribution to the literature.

    Measuring the efficiency of Turkish maternal and child health hospitals: A two-stage data envelopment analysis
    (Pergamon-Elsevier Science Ltd, 2022) Ilgun, Gulnur; Sonmez, Seda; Konca, Murat; Yetim, Birol
    This study aims to examine the changes in efficiency and efficiency levels of the maternal and child health hospitals in Turkey from 2014 to 2017, by applying two-stage data envelopment analysis (DEA). At the first stage of the study, the efficiency of the hospitals was evaluated with input-oriented CCR (Charnes, Cooper, Rhodes) and Malmquist Productivity Index (MPI). At the second stage, panel Tobit regression analysis was utilized to find out the factors that affect the efficiency scores specified at the first stage. According to the results of the first stage, the mean efficiency values calculated for 2014, 2015, 2016, and 2017 were 0.83, 0.90, 0.86, and 0.80, respectively. At the second stage, it was revealed that the variables of not being in a metropolis and having 200 beds at least had statistically a significant effect on the efficiency score (p < 0.05) whereas being a training and research hospital was ineffective (p > 0.05). The number of the studies which assess the efficiency of maternal and child health hospitals in Turkey was quite limited. Moreover, such studies do not contain second-stage analyses. Lastly, it is thought that those results will provide health policy-makers substantial and evidence based information in the allocation of the resources for the related services.

    Prioritization of the policies and practices applied in Turkey to fight against covid-19 through AHP technique
    (Univ Sao Paulo, Fac Saude Publica, 2021) Yetim, Birol; Sönmez, Seda; Konca, Murat; İlgün, Gülnur
    Concerns about covid-19 become deeper globally. Due to these concerns, all countries, international health institutions, health authorities and health care professionals in the world take several measures through policies or practices to control and handle covid-19 pandemic. For example; different types of policies in the fight against covid-19 have been launched in Turkey. Therefore, in this study, we sought to determine how policies and practices against covid-19 were prioritized by health care professionals and other segments of society via AHP method. We observed that the order of importance of health care professionals and other segments of the society regarding the policies and practices used in combating the covid-19 outbreak was quite similar between the groups. The covid-19 test policy was revealed as the most important one of both groups. However, social welfare programs have more significance than economic measures for society, while health care professionals are more concerned with economic measures. With this study, we intend to provide evidence-based information to decision-makers in combating the pandemic.
