Specialization as an organizing principle: the case of ambulatory surgery centers.
The authors conducted an empirical investigation of the relative cost of production in ambulatory surgical centers (ASCs) over varying degrees of specialization. They found that for the majority of ASCs, focus on a specialty was associated with lower facility costs and ASCs appeared to be capturing economies of scale over a broad range of service volume. The authors concluded that these results support the focused factory model of production in the ASC sector.

How robust are reference pricing studies on outpatient medical procedures? Three different preprocessing techniques applied to difference-in differences.
This study assessed the robustness of using preprocessing techniques for difference-in differences in reference pricing studies for outpatient medical procedures. Three different approaches were tested: propensity score reweighting, exact matching, and genetic matching. The three approaches did not yield statistically different results from those previously published.

Cost-effectiveness of a computerized provider order entry system in improving medication safety ambulatory care.
The study objective was to estimate the cost-effectiveness of computerized provider order entry versus traditional paper-based prescribing in reducing medications errors and adverse drug events in the ambulatory setting of mid-sized medical group. Using a decision-analytic model, the researchers found that the adoption of CPOE in the ambulatory setting provides excellent value for the investment.
