The cost of serious fall-related injuries at three Midwestern hospitals.

BACKGROUND: Consequences of fall-related injuries can be both physically and financially costly, yet without current data, hospitals cannot completely determine the financial cost. As part of the analysis for an initiative to minimize falls with injury, the cost and length of stay attributable to serious fall injury were estimated at three hospitals in a Midwestern health care system METHODS: In a retrospective case-control study, 57 hospital inpatients discharged between January 1, 2004, and October 16, 2006, who sustained a serious fall-related injury (fracture, subdural hematoma, any injury resulting in surgical intervention, or death) were identified through the incident reporting system and matched to nonfaller inpatient controls by hospital, age within five years, year of discharge, and diagnosis-related group (DRG). RESULTS: Multivariate analyses indicated that operational costs for fallers with serious injury, as compared with controls, were $13,316 more (p < .01; 95% confidence interval [CI], $1,395-$35,561) and that fallers stayed 6.3 days longer than nonfallers (p < .001; 95% CI, 2.4-14.9). Univariate analyses indicated they were also significantly more likely to have diabetes with organ damage, moderate to severe renal disease, and a higher mean score on the Charlson Comorbidity Index. In optimal bipartite matching (OBM) analyses, fallers with serious injury cost $13,806 more (p < .001; 95% CI, $5,808-$29,450) and stayed 6.9 days longer (p < .001; 95% CI, 2.8-14.9). CONCLUSIONS: Hospital inpatients who sustained a serious fall-related injury had higher total operational costs and longer lengths of stay than nonfallers. Despite possible limitations regarding the cost allocation methods, the analysis included data from three different hospitals, and supplemental multivariate analyses adjusting for academic hospital status did not meaningfully affect the results.

Efficacy and safety of high-dose thromboprophylaxis in morbidly obese inpatients.

Obesity increases the risk for venous thromboembolism (VTE), but whether high-dose thromboprophylaxis is safe and effective in morbidly obese inpatients is unknown. It was the objective of this study to quantify the efficacy and safety of high-dose thromboprophylaxis with heparin or enoxaparin in inpatients with weight > 100 kilograms (kg) within the BJC HealthCare system. Ina retrospective cohort study, we analysed 9,241 inpatients with weight > 100 kg discharged from three hospitals in the BJC HealthCare system from 2010 through 2012. We compared the incidence of VTE in patients who received high-dose thromboprophylaxis (heparin 7,500 units three times daily or enoxaparin 40 mg twice daily) to those who received standard doses (heparin 5,000 units two or three times daily or enoxaparin 40 mg once daily). The primary efficacy outcome was hospital-acquired VTE identified by International Classification of Diseases (ICD)-9 diagnosis codes. The primary safety outcome was bleeding events identified by ICD-9 codes. Among the 3,928 morbidly obese inpatients (weight > 100 kg and body mass index [BMI] ≥ 40 kg/m²), high-dose thromboprophylaxis approximately halved the odds of symptomatic VTE (odds ratio [OR] 0.52, 95% confidence interval [CI] 0.27-1.00; p = 0.050). The rate of VTE was 1.48% (35/2,369) in these morbidly obese inpatients who received standard doses of thromboprophylaxis, compared to 0.77% (12/1,559) in those who received high doses. High-dose thromboprophylaxis did not increase bleeding (OR 0.84, 95% CI 0.66-1.07, p = 0.15). Independent predictors of VTE were surgery, male sex, cancer, and BMI. In conclusion, high-dose thromboprophylaxis nearly halves the rate of VTE in morbidly obese inpatients.

Risk factors for inpatient venous thromboembolism despite thromboprophylaxis.

INTRODUCTION: Venous thromboembolism (VTE) is the most common preventable cause of morbidity and mortality in the hospital. Adequate thromboprophylaxis has reduced the rate of hospital-acquired VTE substantially; however, some inpatients still develop VTE even when they are prescribed thromboprophylaxis. Predictors associated with thromboprophylaxis failure are unclear. In this study, we aimed to identify risk factors for inpatient VTE despite thromboprophylaxis. MATERIALS AND METHODS: We conducted a case-control study to identify independent predictors for inpatient VTE. Among patients discharged from the BJC HealthCare system between January 2010 and May 2011, we matched 94 cases who developed in-hospital VTE while taking thromboprophylaxis to 272 controls who did not develop VTE. Matching was done by hospital, patient age, month and year of discharge. We used multivariate conditional logistic regression to develop a VTE prediction model. RESULTS: We identified five independent risk factors for in-hospital VTE despite thromboprophylaxis: hospitalization for cranial surgery, intensive care unit admission, admission leukocyte count >13,000/mm(3), presence of an indwelling central venous catheter, and admission from a long-term care facility. CONCLUSIONS: We identified five risk factors associated with the development of VTE despite thromboprophylaxis in the hospital setting. By recognizing these high-risk patients, clinicians can prescribe aggressive VTE prophylaxis judiciously and remain vigilant for signs or symptoms of VTE.
