OBJECTIVE To revise and update models in the Mortality Probability Model (MPM II) system to estimate the probability of hospital mortality among 19,124 intensive care unit (ICU) patients that can be used for quality assessment within and among ICUs. DESIGN AND SETTING Models developed and validated on consecutive admissions to adult medical and surgical(More)
To assess the impact of the aging population on the occurrence of fragility fractures, we examined hospital discharges for hip fracture among U.S. women and men aged 45 years and older from 1993 through to 2003. The number of hospitalizations declined by 5%, and age-adjusted rates fell by over 20% for both women and men during this period. Although the(More)
Data at ICU admission and after 24 h in the ICU were collected on 755 patients, to derive multiple logistic regression models for predicting hospital mortality. The derived models contained relatively few and easily obtained variables. The weight associated with each variable was determined objectively. There were seven admission variables, none of which(More)
Estimating prognosis is potentially useful as a measure of ICU performance and as a guide for the clinical care of individual patients. In this study, mortality prediction models (MPMs) for patients in an adult general medical-surgical ICU were derived from data gathered at ICU admission and after 24 and 48 h of ICU care. A predictive model was developed(More)
OBJECTIVE To develop models in the Mortality Probability Model (MPM II) system to estimate the probability of hospital mortality at 48 and 72 hrs in the intensive care unit (ICU), and to test whether the 24-hr Mortality Probability Model (MPM24), developed for use at 24 hrs in the ICU, can be used on a daily basis beyond 24 hrs. DESIGN A prospective,(More)
OBJECTIVES This study assessed the effects of a 2-year integrated health promotion-health protection work-site intervention on changes in dietary habits and cigarette smoking. METHODS A randomized, controlled intervention study used the work site as the unit of intervention and analysis; it included 24 predominantly manufacturing work sites in(More)
BACKGROUND Adults who use wheelchairs have difficulty accessing physicians and receive less preventive care than their able-bodied counterparts. OBJECTIVE To learn about the accessibility of medical and surgical subspecialist practices for patients with mobility impairment. DESIGN A telephone survey was used to try to make an appointment for a fictional(More)
OBJECTIVES To examine the association between income inequality and the risk of mortality and readmission within 30 days of hospitalization. DESIGN Retrospective cohort study of Medicare beneficiaries in the United States. Hierarchical, logistic regression models were developed to estimate the association between income inequality (measured at the US(More)
OBJECTIVES To examine the impact of hospital mortality and intensive care unit (ICU) size on the performance of the Mortality Probability Model II system for use in quality assessment, and to examine the ability of model customization to produce accurate estimates of hospital mortality to characterize patients by severity of illness for clinical trials.

Factors related to hospital resource use by intensive care unit (ICU) patients, including severity of illness at admission and intensity of therapy during the first 24 ICU hours were explored in this study. Analysis was based on 2,749 patients admitted to the general medical-surgical ICU at Baystate Medical Center, Springfield, Massachusetts, between(More)
