Those without invasive ventilatory support were admitted to the hospitalist ICU team, including ones with respiratory failure requiring noninvasive ventilation. Mechanically ventilated patients with intermediate illness severity had lower hospital LOS (10.6 vs 17.8 days, P < 0.001) and ICU LOS (7.2 vs 10.6 days, P = 0.02), and a trend towards decreased in‐hospital mortality (15.6% vs 27.5%, P = 0.10) in the intensivist‐led group. Randomized and multicenter trials are needed to provide more robust data, because our subgroups were small and not accounted for in the sample size calculation. 2012 Mar;7(3):183-9. doi: 10.1002/jhm.972. We adjusted for these and other potential confounders by stratifying patients with SAPS II, examining mechanically ventilated patients separately, and using logistic and linear regression models and propensity scores, recognizing that unmeasured differences in illness severity may remain.29. Patients with several ICU admissions during 1 hospitalization had ICU data collected only from the first ICU entry, consistent with other trials' methodology.1, 4, 10, 1820 Additional ICU entries did not change ICU LOS derived only from the initial entry, but did contribute to hospital LOS. ICU mortality model adjusted for the variables: SAPS II, noninvasive ventilation, MV, CVC, gender; preexisting cancer, cardiovascular and pulmonary diseases. PubMed 7. One of the younger ones said he was pretty exhausted by day 7. Urban academic community hospital affiliated with a major regional academic university. Baumann MH, Simpson SQ, Stahl M, et al. *In‐hospital mortality model adjusted for the variables: SAPS II, MV, CVC, and preexisting cancer. Surprisingly, the presence of an intensivist‐led consult team did not mitigate the mortality and LOS differences seen for mechanically ventilated patients on the hospitalist team. GENMOD, however, does not accommodate several covariates, as it often fails for lack of convergence. Hospitalists may be instrumental in the critical care staffing shortage, however, identification of their ideal role requires further study.AcknowledgementsThe authors thank Ralph Bailey, RN; Daniel S.

Observational studies suggest intensive care unit (ICU) patients have decreased mortality and length of stay (LOS) when cared for by intensivists.111 This prior literature relies on many small, single‐center studies with retrospective designs or historical controls, and compares intensivists to non‐intensivists with concurrent inpatient and outpatient responsibilities.113 These findings are the foundation for patient safety initiatives advocating intensivist involvement with all critically ill patients in urban ICUs.14, Critical care workforce evaluations predict a widening disparity between the United States supply and demand for intensivists,1516 raising concern that national ICU staffing with these specialists is not feasible. 277 Nurse Practitioner Intensivist jobs available on Indeed.com. We present the first prospective evaluation of adult patient outcomes comparing intensivist‐led and hospitalist ICU staffing models. Sample size was determined a priori using an expected inpatient mortality of 10% from historical data, power of 80%, and 2‐sided alpha of 0.05 to demonstrate no difference in outcomes, defined as a mortality difference of <5% between teams. Patient characteristics and outcome data were collected prospectively from medical records and hospital databases by 2 trained research nurses according to study protocol. This prospective observational study studied outcomes in ICU patients cared for by intensivists versus hospitalists, and found the adjusted LOS and mortality was similar overall, but for those mechanically ventilated with intermediate illness severity, intensivist care was associated with shorter LOS and mortality. Outcomes were re‐analyzed using propensity scores within the regression models, yielding similar results that did not change the estimate or improve precision. We next examined mortality differences adjusting only for these 3 variables and were unable to detect a statistically significant mortality difference between the teams (Figure 2). The overall results also remained comparable when calculations were repeated, excluding patient outliers (SAPS II >75 or hospital LOS >30days).Table 3.Adjusted Outcomes Using Logistic Regression Odds Ratios and Linear Regression Length of Stay Differences Adjusted Mortality Difference [%] (95% CI)P ValueAdjusted Mortality OR (95% CI)P ValueMean LOS Difference [days] (95% CI)P ValueNOTE: Mortality rate differences and OR are referent to the hospitalist. We adjusted for these and other potential confounders by stratifying patients with SAPS II, examining mechanically ventilated patients separately, and using logistic and linear regression models and propensity scores, recognizing that unmeasured differences in illness severity may remain.29Our initial adjustment for baseline patient disparities between teams used bivariate analysis with SAPS II to stratify patients into 3 tiers to reflect low (33), intermediate (34‐51), and high (52) disease acuity. The result, however, was inconclusive for patients with mechanical ventilation and did not allow refutation of the null hypothesis because the confidence interval for the mortality rate difference crossed the prespecified mortality difference threshold for clinical significance (Figure 2). Our 2 patient groups had substantial differences in illness severity and mechanical ventilation. Linear regression models also demonstrated no difference in adjusted hospital LOS difference (0.9 days [95% CI: 1.88, 0.12], P = 0.98) and adjusted ICU LOS (0.3 days [95% CI: 0.92, 0.30], P = 0.32) (Table 3). Before going to … This may improve intensivist availability to higher acuity critically ill patients and allow for judicious utilization of the limited intensivist supply. Bottom line: Most hospitalists provide care in the ICU, however hospitalists provide critical care at significantly higher rates in rural and nonacademic hospital settings. How to use intensivist in a sentence. This mortality difference used for the power calculation is consistent with other trial designs.2125 The required sample size was 1306 patients calculated using PASS software (version 2008, NCSS, Kaysville, UT), accounting for an expected 3:2 admission rate to the hospitalists. The use of propensity scores may not fully account for selection biases in team assignments introduced by the ED physicians. Given the complexity of multiple teachers and learners in the ICU environment, we selected shared mental models as our primary theoretical lens through which we analyzed and interpreted our data. MEASUREMENTS: Endpoints were ICU and in‐hospital mortality and LOS, adjusted for patient differences with logistic and linear regression models and propensity scores. CONTINUE SCROLLING OR CLICK HERE FOR RELATED SLIDESHOW. Baseline patient demographics were similar (Table 1). I think it is absolutely a job you could do in your 60s - it's demanding but it's not necessarily physically demanding. … Despite statistical techniques to address potential confounders in observational trials including stratification, multivariable adjustment, and propensity scores,29 residual confounders may still remain that influence the results and thus our conclusions. Hospitalists, on the other hand, often see a patient only during the course of a single hospitalization. Results: Patients who received phenobarbital had significantly shorter stays in the intensive care unit than did those who received therapy based on the CIWA-Ar scale (mean [SD], 2.4 [1.5] vs 4.4 [3.9] days; P < .001).
