SAPS II revisited.

OBJECTIVE: To construct and validate an update of the Simplified Acute Physiology Score II (SAPS II) for the evaluation of clinical performance of Intensive Care Units (ICU). DESIGN AND SETTING: Retrospective analysis of prospectively collected multicenter data in 32 ICUs located in the Paris area belonging to the Cub-Rea database and participating in a performance evaluation project. PATIENTS: 33,471 patients treated between 1999 and 2000. MEASUREMENTS AND RESULTS: Two logistic regression models based on SAPS II were developed to estimate in-hospital mortality among ICU patients. The second model comprised reevaluation of original items of SAPS II and integration of the preadmission location and chronic comorbidity. Internal and external validation were performed. In the two validation samples the most complex model had better calibration than the original SAPS II for in-hospital mortality but its discrimination was not significantly higher (area under ROC curve 0.89 vs. 0.87 for SAPS II). Second-level customization and integration of new items improved uniformity of fit for various categories of patients except for diagnosis-related groups. The rank order of ICUs was modified according to the model used. CONCLUSIONS: The overall performance of SAPS II derived models was good, even in the context of a community cohort and routinely gathered data. However, one-half the variation of outcome remains unexplained after controlling for admission characteristics, and uniformity of prediction across diagnostic subgroups was not achieved. Differences in case-mix still limit comparisons of quality of care.

Culture, organization, and management in intensive care: construction and validation of a multidimensional questionnaire.

OBJECTIVE: The objective of this study is to develop and validate a questionnaire designed to assess the culture, organization, and management of intensive care units. DESIGN: This is a prospective multicenter study. SETTING: The study was conducted in 26 intensive care units located in Paris. PARTICIPANTS: All personnel were asked to complete the questionnaire. INTERVENTION: The questionnaire was developed in 2 steps: (1) development of a theoretical framework based on organizational theory and (2) testing of the reliability and validity of a comprehensive set of measures. METHOD: The internal consistency of the items composing each scale was tested by using the Cronbach alpha. Convergent, and discriminant validity was assessed by factor analysis with varimax rotation. RESULTS: The overall completion rate was 74% with 1000 respondents (750 nurses, 26 head nurses, 168 physicians, and 56 medical secretaries). Starting with a 220-item questionnaire, we constructed a short version-conserving metrological characteristics with good reliability and validity. The short questionnaire, entitled Culture, Organization, and Management in Intensive Care, consists of 106 items distributed in 9 dimensions and 22 scales: culture (n = 3), coordination and adaptation to uncertainty (n = 3), communication (n = 3), problem solving and conflict management (n = 2), organizational learning and organizational change (n = 2), skills developed in a patient-caregiver relationship (n = 1), subjective unit performance (n = 3), burnout (n = 3), and job satisfaction and intention to quit (n = 2). All the scales showed good-to-high reliability, with Cronbach alpha scores higher than .7 (with the exception of coordination [.6]). Team satisfaction-oriented culture is positively correlated with good managerial practices and individual well-being. CONCLUSIONS: The Culture, Organization, and Management in Intensive Care questionnaire enables staff and managers to assess the organizational performance of their intensive care unit.

Designing adverse event prevention programs using quality management methods: the case of falls in hospital.

OBJECTIVE: From a public health perspective, the effectiveness of any prevention program depends on integrated medical and managerial strategies. In this way, quality management methods drawn from organization and business management can help design prevention programs. The aim of this study was to analyze the potential value of these methods in the specific context of preventing falls in hospital. SETTING: Medical and Rehabilitation Care Unit of Saint-Maurice National Hospital (France). DESIGN: In phase 1, two surveys assessed the context in which falls occurred. The first survey (1995) quantified adverse events during a 1-year period (n = 564) and the second (1996-1997) documented the reasons for falls (n = 53). In phase 2, a set of recommendations to prevent falls was elaborated and implemented throughout the hospital. RESULTS: The fall frequency in this unit was 18.3% in 1995. Analysis showed organizational causes in 35 (66%) of the 53 documented falls; 24 of them were associated with individual factors. Even though the two categories of causes are interdependent, their distinction enables specific recommendations. The proposed organizational management changes recommended do not aim to achieve an illusory objective of 'zero falls', but are designed to reduce the number of avoidable falls and to limit the negative consequences of unavoidable falls. CONCLUSION: Quality improvement methods shed new light on how to prevent falls. An unexploited potential for prevention lies in organization and management of care for hospitalized patients.
