Evaluating Organizational Change in Health Care: The Patient-Centered Hospital Model

Background: An increasing number of hospitals react to recent demographic, epidemiological and managerial challenges moving from a traditional organizational model, based on functional departments, to a Patient-Centered (PC) hospital model, which is better capable of sustaining new processes of care. Although the theoretical managerial literature on the PC hospital model is vast, quantitative evaluations of the performance of hospitals that moved from the traditional to the PC organizational structure is scarce. However, quantitative analysis of effects of managerial changes is important and can provide additional argument in support of innovation. Methods: We take advantage of a quasi-experimental setting and of a unique administrative data set on the population of hospital discharge charts (HDCs) over a period of 9 years of Lombardy, the richest and one of the most populated region of Italy, larger than the median EU28 country by population and about the size of Sweden. During this period three important hospitals switched to the PC model in 2010, whereas all the others remained with the functional organizational model. This allowed us to develop a difference-in-difference analysis of some selected measures of efficiency and effectiveness for PC hospitals. As efficiency indicators, we use the number of a patient's transfers within the hospital and the duration of his hospitalization. As effciency indicators, we use the likelihood of readmission of a patient within the same hospital, of readmission in a different hospital within the same region and the mortality rate of a discharged patient. Given our interest in the average hospital performance after switching to the PC model, we focus on the "between-variability" of the 25 major diagnostic categories (MDCs) in each hospital by first collapsing individual HDC's efficiency and effectiveness to the average MDC in each hospital and then by estimating a difference-in-difference model. This allows an analysis of before-after changes in average MDC effectiveness and efficiency of hospitals that switched to the PC model as opposed to those of the rest of the hospitals, which maintained the functional organization. Results: We contribute to the literature that addresses the evaluation of healthcare and hospital change by providing a quantitative estimation of efficiency and effectiveness changes following to the implementation of the PC hospital model. Results show that both efficiency and effectiveness have significantly increased in the average MDC of PC hospitals, thus confirming the need for policy makers to invest in new organizational models close to the principles of PC hospital structures. Conclusions: Conclusions: Although the shift to a different hospital model may follow international trends and may be moved by interests or beliefs but lack with ex ante impact evaluation, ex-post evaluation remain a fundamental activity and it should be used its important policy implications for future innovations. Although an organizational change towards the PC model can be a costly process, implying a rebalancing of responsibilities and power among hospital personnel (e.g. medical and nursing staff), our results suggest that changing towards a PC model can be worthwhile in terms of both efficacy and efficiency. This evidence can be used to inform and sustain hospital managers and policy makers in their hospital design efforts and to communicate the innovation advantages within the hospital organizations, among the personnel and in the public debate.
