HOSPITALS MOTIVATIONS IN ESTABLISHING OR CLOSING GERIATRIC EVALUATIONMANAGEMENT UNITS - DIFFUSION OF A NEW PATIENT-CARE TECHNOLOGY IN A CHANGING HEALTH-CARE ENVIRONMENT

Background. Although Geriatric Evaluation Management Units (GEMs) are beneficial to patients, they are still new and their adoption by hospi tals is unknown. This study describes the adoption of GEMs in a large sample of hospitals, and explores the reasons underlying hospitals' de cisions to open (and sometimes close) an inpatient GEM. Methods. A nat ionwide mail survey was conducted of 3,655 hospitals. The survey asked whether the hospital had an operating GEM, had a GEM that closed, had considered opening a GEM (but had not done so), or had not considered opening a GEM. The survey also requested specific information about o perating or closed GEMs. Descriptive statistics, chi-square, t-tests, one-way analysis of variance, and Tukey's standardized range test for multiple comparison of means were used to analyze the responses. Resul ts. Among the 1,639 responding hospitals, 159 had established GEMs, 20 0 were evaluating the possibility of opening a GEM, and 1,263 had neit her opened nor considered opening a GEM. Adopters were more likely to be large, urban, teaching hospitals. Evaluators were more optimistic t han adopters about GEM's potential to meet financial goals. GEMs that closed tended to be located in hospitals experiencing budget deficits. Among adopters, space and nonphysician staffing were the most critica l barriers to establishing a GEM whereas, for evaluators, identifying reimbursement sources and physician staffing were the greatest barrier s. VA GEMs are smaller and initiated for different reasons than non-VA hospital GEMs. Conclusions. Despite their demonstrated usefulness, th e adoption of GEMs has been limited. The reasons underlying decisions to adopt this new technology or close a GEM are often related to finan cial, not clinical concerns.
