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.

Treatment intensity and outcome of patients aged 80 and older in intensive care units: a multicenter matched-cohort study.
OBJECTIVES: To determine whether patients aged 80 and older have similar treatment intensity to that of younger patients in the intensive care unit (ICU). DESIGN: Multicenter, matched-cohort study. SETTING: Data were extracted from a multicenter database with 36 ICUs in the Paris area (France) during a 4-year period (1997-2000). PARTICIPANTS: Three thousand one hundred seventy-five patients aged 80 and older (oldest-old) were retrospectively matched to 3,175 patients aged 65 to 79 (young-old). MEASUREMENTS: The matching criteria were severity status on admission (+/-2) (assessed using a corrected Simplified Acute Physiology Score II leaving out age points), Charlson Comorbidity Index, type of admission (surgical vs medical), sex, admission to same ICU, and year of ICU admission. The underlying condition was classified using the McCabe classification. The functional status was assessed using the Knaus classification. The ICU workload was assessed using the OMEGA scoring system. RESULTS: Total and daily workload were lower in the oldest-old than in matched young-old patients. Estimated mean direct medical cost per stay was approximately 1,280 dollars lower for oldest-old patients. Older patients received less mechanical ventilation (adjusted odds ratio (AOR)=0.69, 95% confidence interval (CI)=0.61-0.78), less tracheostomy (AOR=0.37, 95% CI=0.28-0.50), and less renal support (AOR=0.52, 95% CI=0.41-0.66) than matched young-old patients. Oldest-old patients had a shorter length of ICU stay than matched young-old patients and the same length of post-ICU stay. CONCLUSION: Oldest-old patients receive less treatment in the ICU than young-old patients even after adjustment for severity of illness.

Prognosis of patients aged 80 years and over admitted in medical intensive care unit.
OBJECTIVE: To determine the prognostic indicators of long-term survival after admission to a medical intensive care unit (MICU) for patients aged 80 years and over. DESIGN. Prospective cohort study. SETTING: A 14-bed MICU in a 970-bed, acute care, tertiary, university hospital in Paris, France. PATIENTS: A total of 233 patients aged 80 years and over discharged from a MICU during a 2-year period. MEASUREMENTS AND MAIN RESULTS: Severity at admission was estimated using the Simplified Acute Physiology Score. The underlying condition was classified using the MacCabe classification. The functional status was assessed using the Knaus classification. The outcome after MICU discharge was determined after a median 2-year follow-up. The functional outcome was assessed by telephone interviews, employing the Instrumental Activities of Daily Living (IADL). The in-MICU mortality was 19.5% including death occurring during the 2 days following discharge. The long-term survival rates for patients admitted to the MICU were 59% at 2 months, 33% at 2 years, and 29% at 3 years. The multivariate analysis identified two prognostic factors of death after discharge: presence of an underlying fatal disease (HR 1.7; 95% CI 1.1-2.6) and severe functional limitation (HR 1.7; 95% CI 1.2-2.6). The IADL was excellent or good for 56% of the surviving patients. CONCLUSION: Long-term survival after MICU is mainly related to the underlying condition, whereas known factors for in-MICU survival do not influence long-term prognosis.

[Epidemiology and heat waves: analysis of the 2003 episode in France].
Epidemiology and heat waves: analysis of the 2003 episode in France. The heat wave that struck France in 2003 has been accompanied with an estimated 15,000 excess deaths. This paper stresses the difficulties of the epidemiology of such an event. The relevant clinical and biological information is incomplete or even inaccessible and many of the deaths are due to multiple factors. The data presently available indicate that the deaths occurred in persons already vulnerable, and that the heat wave caused a five- to eight-month loss of lifetime for the affected individuals. There is a noteworthy similarity between the profiles of this exceptional summer mortality surge, and those of many past winters when similar or larger excess mortalities ave occurred without as yet eliciting much public attention.
