East-west: does it make a difference to hospital efficiencies in Ukraine?

Ukraine's history has given it a split personality (e.g. divergent cultural influences on economic and managerial behavior), as was observed in the recent political developments both prior to and following the December 2004 elections. Eastern regions were heavily influenced by Russo-Soviet rule, while western regions have more of a European outlook. This study, which is largely exploratory, compares recent trends in hospital efficiency in Ukraine to see if this split personality manifests itself in differential rates of improvement. Given the inflexibility of Soviet-style planned economies, it is hypothesized that western regions will show greater improvement in economic efficiency that can be attributed to higher levels of managerial and medical entrepreneurship. Data for this study comes from three oblasts (i.e. geopolitical regions), one in the west and two in the east, spanning from 1997 to 2001. Data envelopment analysis (DEA) was used to estimate technical efficiency for the hospitals. After correcting for bias, a second-stage Tobit regression was estimated. Results indicate that hospitals in the west improved efficiencies, while those in the east stayed constant. These western areas of the nation, being more amenable to western management and medical 'business' practice, may be quicker to pick up on new techniques to increase healthcare delivery efficiencies. This may stem from the more limited effects of a shorter history of incorporation into a Soviet-style planned and controlled economy in which individual decision-making and entrepreneurship was suppressed in favor of central decision-making by the state.

Analysis of uncompensated hospital care using a DEA model of output congestion.

Uncompensated care can create financial difficulties for hospitals. The problem is likely to worsen as the number of individuals lacking health insurance continues to grow. The objective of this study is to measure how uncompensated care affects hospitals' ability to provide the services for which they do receive compensation. Applying output-based data envelopment analysis (DEA) under various assumptions on the disposability of outputs to a sample of Pennsylvania hospitals, we find that, on average, hospitals could have produced 7% more output if they had all operated on the best-practice frontier and that uncompensated care reduced the production of other hospital outputs by 2%. Thus, even if hospitals were to operate efficiently, they might still face financial distress as a result of providing uncompensated care. The findings in our study suggest that policy makers should continue looking at ways to increase funding to hospitals providing uncompensated care while not distorting economic incentives to reduce excessive costs.

Service collaboration and hospital cost performance: direct and moderating effects.

BACKGROUND: Growing reliance on service provision through systems and networks creates the need to better understand the nature of the relationship between service collaboration and hospital performance and the conditions that affect this relationship. OBJECTIVE: We examine 1) the effects of service provision through health systems and health networks on hospital cost performance and 2) the moderating effects of market conditions and service differentiation on the collaboration-cost relationship. RESEARCH DESIGN: We used moderated regression analysis to test the direct and moderating effects. Data on 1368 private hospitals came from the 1998 AHA Annual Survey, Medicare Cost Reports, and Solucient. MEASURES: Service collaboration was measured as the proportion of hospital services provided at the system level and at the network level. Market conditions were measured by the levels of managed care penetration and competition in the hospital's market. RESULTS: The proportion of hospital services provided at the system level had a negative relationship with hospital cost. The relationship was curvilinear for network use. Degree of managed care penetration moderated the relationship between network-based collaboration and hospital cost. CONCLUSION: The benefits of service collaboration through systems and networks, as measured by reduced cost, depend on degree of collaboration rather than mere membership. In loosely structured collaborations such as networks, costs reduce initially but increase later as the extent of collaboration increases. The effect of network-based collaboration is also tempered by managed care penetration. These effects are not seen in more tightly integrated forms such as systems.

Performance of US teaching hospitals: a panel analysis of cost inefficiency.

This research summarizes an analysis of the impact of environment pressures on hospital inefficiency during the period 1990-1999. The panel design included 616 hospitals. Of these, 211 were academic medical centers and 415 were hospitals with smaller teaching programs. The primary sources of data were the American Hospital Association's Annual Survey of Hospitals and Medicare Cost Reports. Hospital inefficiency was estimated by a regression technique called stochastic frontier analysis. This technique estimates a "best practice cost frontier" for each hospital that is based on the hospital's outputs and input prices. The cost efficiency of each hospital was defined as the ratio of the stochastic frontier total costs to observed total costs. Average inefficiency declined from 14.35% in 1990 to 11.42% in 1998. It increased to 11.78% in 1999. Decreases in inefficiency were associated with the HMO penetration rate and time. Increases in inefficiency were associated with for-profit ownership status and Medicare share of admissions. The implementation of the provisions of the Balanced Budget Act of 1997 was followed by a small decrease in average hospital inefficiency. Analysis found that the SFA results were moderately sensitive to the specification of the teaching output variable. Thus, although the SFA technique can be useful for detecting differences in inefficiency between groups of hospitals (i.e., those with high versus those with low Medicare shares or for-profit versus not-for-profit hospitals), its relatively low precision indicates it should not be used for exact estimates of the magnitude of differences associated with inefficiency-effects variables.

Performance of major teaching hospitals during the 1990s: adapting to turbulent times.

A panel design was used to analyze changes in performance variables related to profitability, volume, and efficiency in a national sample of major teaching hospitals from 1990 to 1999. After steady increases beginning in 1990, the average total margin ratio peaked in 1996 and by 1999 it declined by almost 50 percent. Average operating margins were negative every year. Major teaching hospitals responded to financial pressures by expanding outpatient activity, reducing length of stay, downsizing inpatient capacity, and increasing labor productivity. Membership in multi-hospital systems increased by over 70 percent through the 1990s. Increases in average real cost per adjusted admission peaked in 1994 and fell by 6 percent from 1994 to 1999.

Correlates of hospital provision of prevention and health promotion services.

This study investigates the factors associated with hospital provision of prevention and health promotion services. The authors conceptualize the provision of these services as a hospital response to the community health concerns of environmental stakeholders. The response depends on hospital recognition and interpretation of institutional and resource dependence pressures and is related to interorganizational linkages, resource dependencies, and information processing structure. Data for the study came from 3,453 U.S. hospitals. The authors found that hospital provision of prevention and health promotion services is positively related to alliance and network membership, the diffusion of such services among other area hospitals, the use of community health status information, and hospital size. Also, for-profit hospitals provide fewer prevention and health promotion services than not-for-profit hospitals. These findings have policy and management implications.

The supply of uncompensated care in Pennsylvania hospitals: motives and financial consequences.

The need for uncompensated care has increased during a period in which hospitals are confronted with public and private-sector fiscal pressures. Using a panel design (1995--1998) on Pennsylvania private, not-for-profit general hospitals, we found the provision of uncompensated care is positively associated with financial surpluses, the provision of uncompensated care by neighboring hospitals, bed capacity, proportion of outpatient visits that are emergency, and the unemployment rate (a proxy for need for uncompensated care). Other analysis found that the provision of uncompensated care was not associated with operating surplus, except in hospitals that provide very large amounts of uncompensated care. Provision of services to Medicaid patients and HMO penetration had a negative impact on profitability.

Impact of network and system use on hospital X-inefficiency.

A significant part of the restructuring in the health care industry has involved hospitals joining health networks and health systems. While the proclaimed purpose of this strategy has been to improve hospital performance, studies have found that not all member hospitals reap the desired outcomes. Variations in performance have been linked to, among other things, service provision at the network/system level versus individual hospital level. This study examined the impact of network and system use to provide services on hospital X-inefficiency (i.e., the difference between actual and optimal costs) in a national sample (n = 1,368) of U.S. urban, general, hospitals. Stochastic frontier analysis (SFA) revealed a mean hospital X-inefficiency of 14.85%. Results suggest that hospitals providing a moderate to high proportion of services at the network or system level were more efficient than hospitals that did not use networks or systems for service provision. Low users of networks or systems and nonusers had comparable levels of efficiency.
