Systematic reviews have surveyed the literature associated with DEA and identified the most influential journals in the fields of DEA and its applications in the period 1978–2019 ( 26–30). Despite its uncertainty ( 11), it is a promising way to estimate the efficiency of units in many areas, including health care systems ( 12, 13), reform ( 14, 15), PHC centres (see 54 publications in Supplementary Table S1), regions ( 16–20), dental units ( 21), emergency departments ( 22) and hospitals ( 10, 23–25). Since its inception 40 years ago, DEA has been extensively investigated and applied as a tool ( 10). It is based on the principle that an organization can be considered efficient when it is able to obtain the greatest output, in terms of goods, products or feasible services, by using a certain combination of used resources as input or, alternatively, when it produces a certain level of output using the least possible input ( 8, 9).

DEA ( 7) uses a linear programming technique that gives a single measure of efficiency. Recent years have seen a growth in interest in the use of quantitative methods for comparing the efficiency of health care systems ( 2, 4, 5), and many approaches for estimating the efficiency of various levels of health care organizations are under intensive investigation ( 6).ĭata envelopment analysis (DEA) ( 7) is a non-parametric, deterministic alternative to several efficiency measurement techniques, such as the cost-effectiveness ratio, corrected ordinary least squares or stochastic frontier analysis. Moreover, better use of health care resources could lead to the provision of better health services at the basic level.

Measuring the relative efficiency of health care systems, including primary health care (PHC) centres, creates a baseline for evaluating the management of their resources and for benchmarking their productiveness against others. Many countries have a growing demand for health care services and this is accompanied by growing expenditure ( 1–3). We identify various approaches to effective assessment of primary care.ĭata envelopment analysis is widely used in primary care.Ī variety of analysis models exist, with no single standard.
