Effects of a nonsurgical hospitalist service on trauma patient outcomes.

Surgery. 2009 Apr;145(4):355-61

BACKGROUND: The American College of Surgeons criteria for Level I trauma centers calls for >90% of trauma patients to be admitted directly by a trauma surgeon or surgical subspecialist; however, the efficiency of the trauma system may be increased if patients presenting with comorbid conditions and minor injuries are treated by a hospitalist team (nonsurgical Trauma MEDical [TMED] service). We hypothesized outcomes would be equivalent for patients treated under TMED versus a surgical service. METHODS: This retrospective review compared mortality, hospital length of stay (LOS), Emergency Department (ED) LOS, placement to rehabilitation facilities, and complication rates for patients who could have been treated by TMED as identified by an algorithm. The study population for 2003 (pre-TMED) was compared with the study population for 2006 (post-TMED). Univariate analyses and multivariate logistic and linear regression were used to identify outcomes that were different for patients treated in 2003 versus 2006. Sensitivity, specificity, and percent kappa agreement were calculated for patients who were treated by the TMED team in 2006 versus patients in 2006 who were identified using the algorithm. RESULTS: The algorithm had reasonable sensitivity (78%) and specificity (90%); the kappa agreement was excellent (0.88). No differences were found in mortality (P = .31), rate of complications (P = .08), ED LOS (P = .77), or placement to rehabilitation facilities (P = .29) for patients identified in 2003 versus 2006. Hospital LOS was increased in 2006 (3.7 vs 4.1 days; P = .02). CONCLUSION: These data support admission of trauma patients with nonsevere, single-system injuries to a nonsurgical hospitalist service. We hypothesize that overall system efficiency may be improved by applying this alternative model in other trauma centers.

How should age at diagnosis impact treatment strategy in asymptomatic primary hyperparathyroidism? A cost-effectiveness analysis.

Surgery. 2008 Aug;144(2):290-8

Authors: Zanocco K, Sturgeon C

BACKGROUND: The National Institutes of Health consensus conference on asymptomatic primary hyperparathyroidism (PHPT) recommended several criteria for parathyroidectomy (PTX), including age <50 years. We hypothesized that a cost-effectiveness analysis would show PTX to be the optimal strategy for asymptomatic patients >50 years of age. METHODS: A Markov model was constructed comparing operative, observational, and pharmacologic treatments. Costs were estimated from a third-party payer perspective. Outcomes were weighted with utility adjustment factors, yielding quality-adjusted life-years (QALYs). Future costs and QALYs were discounted at 3%. Threshold analysis identified the optimal strategy at life expectancies ranging from 6 months to 75 years. Multivariate sensitivity analysis was completed with Monte Carlo simulation. RESULTS: PTX was optimal when life expectancy reached 5 years for outpatient PTX and 6.5 years for inpatient PTX. Observation was the optimal strategy at all shorter life expectancies considered. The pharmacologic treatment strategy was not optimal at any life expectancy. CONCLUSION: PTX is the optimal strategy for many patients with asymptomatic PHPT who are >50 years of age. PTX is cost effective for patients with a predicted life expectancy of 5 years (outpatient) or 6.5 years (inpatient). For patients with a shorter life expectancy, observation is the most cost-effective strategy.

Risk factors for the development of fulminant Clostridium difficile colitis.

Surgery. 2008 May;143(5):623-9

Authors: Greenstein AJ, Byrn JC, Zhang LP, Swedish KA, Jahn AE, Divino CM

BACKGROUND: The development of fulminant Clostridium difficile colitis (FCDC) requires prompt operative intervention and is associated with a high mortality rate. The aim of this study was to use a case-control design to define the clinical and laboratory parameters that predict which patients with Clostridium difficile infection are most likely to progress to FCDC. METHODS: Cases from 1994 to 2006 with documented in-hospital progression of Clostridium difficile infection to FCDC were matched retrospectively at the start of medical therapy by age, sex, and intensive care unit (ICU) status to controls with Clostridium difficile infection who did not develop FCDC. Chi-Square and multivariable logistic regression were used to identify risk factors for progression to FCDC. RESULTS: A total of 35 patients with FCDC were matched to 70 controls with Clostridium difficile infection who did not develop FCDC. The patients with FCDC underwent colectomy after an average of 4.6 days of medical therapy and had a mortality rate of 40%. On multivariate analysis, independent risk factors for the development of FCDC were a WBC > 16,000 cells/mm(3) (P < .01) at initiation of therapy, operative therapy within the last 30 days (P = .03), a history of inflammatory bowel disease (P = .04), and a history of intravenous immunoglobulin treatment (P < .01). CONCLUSIONS: Leukocytosis, recent prior operative therapy, and a history of inflammatory bowel disease and intravenous immunoglobulin treatment were negative prognostic indicators for patients with Clostridium difficile infection. The presence of these factors merits close observation for progression to FCDC and acceleration of the planning process for operative intervention.
