Primary Care Efficiency Measurement Using Data Envelopment Analysis: A Systematic Review

Abstract

There is a gap between the demand and supply of efficiency analyses within primary care (PC), despite the threatening financial sustainability of health care systems. This paper provides a systematic literature review on PC efficiency analysis using Data Envelopment Analysis (DEA). We reviewed 39 DEA applications in PC, to understand how methodological frameworks impact results and influence the information provided to decision makers. Studies were combined using qualitative narrative synthesis. This paper reports data for each efficiency analysis on the: 1) evaluation context; 2) model specifications; 3) application of methods to test the robustness of findings; 4) presentation of results. Even though a consistent number of analyses aim to support policymakers and practice managers in improving the efficiency of their PC organizations, the results indicate that DEA--at least when applied to PC--is a methodology still in progress; it needs to be further advanced to meet the complexity that characterizes the production of PC outcomes. Future studies are needed to fill some gaps in this particular domain of research, such as on the standardization of methodologies and the improvement of outcome research in PC. Most importantly, further studies should include extensive uncertainty analyses and be based on good evidence-based rationales. We suggest a number of considerations to academics and researchers to foster the utility of efficiency measurement for the decision making purposes in PC.

Going beyond health efficiency: What really matters?

“…As described above, in the literature the efficiency of a country's hospitals is measured more often than the health system as a whole. Consequently, papers that review the literature on the measurement of healthcare efficiency also emphasize hospitals . Varabyova and Müller systematize previous works on the efficiency of healthcare systems in different countries by reviewing 22 such studies conducted before August 2014.…”

Measuring Efficiency of the New Zealand District Health Boards: An Empirical Research Using Two‐Stage Data Envelopment Analysis

“…For hospitals, capital investment, labour and other operating expenses are the main inputs, whereas inpatients and outpatients are the key outputs (O'Neill et al, 2008;Cantor & Poh, 2018). Regarding primary care, the outputs might be activities (number of visits or examinations), quality indicators or health outcomes (Pelone et al, 2015).…”

Health Efficiency Measurement in Turkey By Using Data Envelopment Analysis: A Systematic Review

“…Pelone et al (2015) compiled studies that measure the efficiency of institutions that provide primary health care using DEA. 21 As a result of certain criteria, a total of 39 studies have been reviewed. In theirstudy, some features such as countries where the studies are conducted, the types and numbers of decision-making units and the models are mentioned.…”
