Epidemiology and outcomes in patients with severe sepsis admitted to the hospital wards.

PURPOSE: The purpose of this study was to detail the trajectory and outcomes of patients with severe sepsis admitted from the emergency department to a non-intensive care unit (ICU) setting and identify risk factors associated with adverse outcomes. MATERIAL AND METHODS: This was a single-center retrospective cohort study conducted at a tertiary, academic hospital in the United States between 2005 and 2009. The primary outcome was a composite outcome of ICU transfer within 48 hours of admission and/or 28-day mortality. RESULTS: Of 1853 patients admitted with severe sepsis, 841 (45%) were admitted to a non-ICU setting, the rate increased over time (P < .001), and 12.5% of these patients were transferred to the ICU within 48 hours and/or died within 28 days. In multivariable models, age (P < .001), an oncology diagnosis (P < .001), and illness severity as measured by Acute Physiologic and Chronic Health Evaluation II (P = .04) and high (≥4 mmol/L) initial serum lactate levels (P = .005) were associated with the primary outcome. CONCLUSIONS: Patients presenting to the emergency department with severe sepsis were frequently admitted to a non-ICU setting, and the rate increased over time. Of 8 patients admitted to the hospital ward, one was transferred to the ICU within 48 hours and/or died within 28 days of admission. Factors present at admission were identified that were associated with adverse outcomes.

The Mortality Review Committee: a novel and scalable approach to reducing inpatient mortality.

BACKGROUND: Despite the importance of reducing inpatient mortality, little has been reported about establishing a hospitalwide, systematic process to review and address inpatient deaths. In 2006 the University of Pennsylvania Health System's Mortality Review Committee was established and charged with reducing inpatient mortality as measured by the mortality index--observed/expected mortality. METHODS: Between 2006 and 2012, through interdisciplinary meetings and analysis of administrative data and chart reviews, the Mortality Review Committee identified a number of opportunities for improvement in the quality of patient care. Several programmatic interventions, such as those aimed at improving sepsis and delirium recognition and management, were initiated through the committee. RESULTS: During the committee's first six years of activity, the University HealthSystem Consortium (UHC) mortality index decreased from 1.08 to 0.53, with observed mortality decreasing from 2.45% to 1.62%. Interventions aimed at improving sepsis management implemented between 2007 and 2008 were associated with increases in severe sepsis survival from 40% to 56% and septic shock survival from 42% to 54%. The mortality index for sepsis decreased from 2.45 to 0.88. Efforts aimed at improving delirium management implemented between 2008 and 2009 were associated with an increase in the proportion of patients receiving a "timely" intervention from 18% to 57% and with a twofold increase in the percentage of patients discharged to home. DISCUSSION: The establishment of a mortality review committee was associated with a significant reduction in the mortality index. Keys to success include interdisciplinary membership, partnerships with local providers, and a multipronged approach to identifying important clinical opportunities and to implementing effective interventions.

Preventable mortality: does the perspective matter when determining preventability?

BACKGROUND: We report a novel approach to mortality review using a 360° survey and a multidisciplinary mortality committee (MMC) to optimize efforts to improve inpatient care. METHODS: In 2009, a 16-item, 360° compulsory quality improvement survey was implemented for mortality review. Descriptive statistics were performed to compare the responses by provider specialty, profession, and level of training using the Fisher exact and chi-square tests, as appropriate. We compared the agreement between the MMC review and provider-reported classification regarding the preventability of each death using the Cohen kappa coefficient. A qualitative review of 360° information was performed to identify the quality opportunities. RESULTS: Completed surveys (n = 3095) were submitted for 1683 patients. The possibility of a preventable death was suggested in the 360° survey for 42 patients (1.40%). We identified 502 patients (29.83%) with completed 360° surveys who underwent MMC review. The inter-rater reliability between the provider opinions regarding preventable death and the MMC review was poor (kappa = 0.10, P < 0.001). Of the 42 cases identified by the 360° survey as preventable deaths, 15 underwent MMC review; 3 were classified as preventable and 12 were deemed unavoidable. Qualitative analyses of the 12 discrepancies did reveal quality issues; however, they were not deemed responsible for the patients' death. CONCLUSIONS: The mortality survey yielded important information regarding inpatient deaths that historically was buried with the patient. Poor agreement between the 360° survey responses and an objective MMC review support the need to have a multipronged approach to evaluating inpatient mortality.

Severe sepsis cohorts derived from claims-based strategies appear to be biased toward a more severely ill patient population.

OBJECTIVE: The epidemiology of severe sepsis is derived from administrative databases that rely on International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) codes to select cases. We compared the sensitivity of two code abstraction methods in identifying severe sepsis cases using a severe sepsis registry. DESIGN: Single-center retrospective cohort study. SETTING: Tertiary care, Academic, University Hospital. PATIENTS: One thousand seven hundred thirty-five patients with severe sepsis or septic shock. INTERVENTIONS: None. MEASUREMENTS: Proportion identified as severe sepsis using two code abstraction methods: 1) the new specific ICD-9 codes for severe sepsis and septic shock, and 2) a validated method requiring two ICD-9 codes for infection and end-organ dysfunction. Multivariable logistic regression was performed to determine sociodemographics and clinical characteristics associated with documentation and coding accuracy. MAIN RESULTS: The strategy combining a code for infection and end-organ dysfunction was more sensitive in identifying cases than the method requiring specific ICD-9 codes for severe sepsis or septic shock (47% vs. 21%). Elevated serum lactate level (p<0.001), ICU admission (p<0.001), presence of shock (p<0.001), bacteremia as the source of sepsis (p=0.02), and increased Acute Physiology and Chronic Health Evaluation II score (p<0.001) were independently associated with being appropriately documented and coded. The 28-day mortality was significantly higher in those who were accurately documented/coded (41%, compared with 14% in those who were not, p<0.001), reflective of a more severe presentation on admission. CONCLUSIONS: Patients admitted with severe sepsis and septic shock were incompletely documented and under-coded, using either ICD-9 code abstracting method. Documentation of subsequent coding of severe sepsis was more common in more severely ill patients. These findings are important when evaluating current national estimates and when interpreting epidemiologic studies of severe sepsis as cohorts derived from claims-based strategies appear to be biased toward a more severely ill patient population.

The surgery clerkship: an opportunity for preclinical credentialing in urinary catheterization.

BACKGROUND: At our hospital, medical students lost privileges to perform urinary catheterization because of concern regarding catheter-associated urinary tract infections. We hypothesized that trained medical students could perform urinary catheterization with the same proficiency as licensed practitioners. METHODS: Medical students completed a credentialing program in urinary catheterization. Prospectively, the rate of catheter-associated urinary tract infections after urinary catheterization performed by medical students was compared with the health system-wide rate of catheter-associated urinary tract infections after urinary catheterization performed by non-medical students using an incidence rate ratio (IRR). RESULTS: Over 9 months, a total of 432 and 55,401 catheter days accrued in patients who underwent urinary catheterization by medial students and non-medical students, resulting in 1 and 129 catheter-associated urinary tract infections, respectively. The incidence rate of catheter-associated urinary tract infections per 1,000 catheter days was 2.31 in the medical student-placed catheters and 2.33 in the non-MS-placed catheters (IRR = .99, P = .55). CONCLUSIONS: Preclinical credentialing in urinary catheterization resulted in the reinstatement of urinary catheterization privileges to qualified medical students. Student proficiency in urinary catheterization can match that of licensed practitioners.

Timing of preoperative pharmacoprophylaxis for pancreatic surgery patients: a venous thromboembolism reduction initiative.

BACKGROUND: Venous thromboembolism (VTE) remains a clinical problem in surgical oncology. We report the impact of preoperative initiation of subcutaneous heparin on VTE events after pancreatic surgery. METHODS: A retrospective cohort study of patients undergoing pancreatic surgery by a single surgeon and enrolled in the American College of Surgeons National Surgery Quality Improvement Program database (FY09/10) was performed. In FY10, a protocol was developed to encourage the use of preoperative pharmacoprophylaxis for high-risk patients. We compared patient characteristics before and after implementation of the protocol. Our primary outcome was 30-day VTE rate and secondary outcomes were bleeding events and 30-day mortality. Outcomes were compared by Student's t-test and Fisher's exact test. RESULTS: Seventy-three patients were studied, 34 patients underwent surgery before and 39 had surgery after implementation of the protocol. All patients received intra-operative intermittent compression boots (ICB) and postoperative pharmacoprophylaxis. Patients in the two groups were statistically equivalent with respect to age, body mass index, procedure length, and VTE risk factors. The percentage of patients with a VTE event decreased significantly after the protocol (17.6% vs. 2.6%, P=0.035). The mean number of units of red blood cells transfused in the OR was not statistically different (0.4 vs. 0.7, P=0.43.) Two patients returned to the operating room for bleeding after the implementation of the protocol. There were no deaths. CONCLUSIONS: Intraoperative ICBs with postoperative initiation of subcutaneous heparin pharmacoprophylaxis may be inadequate for VTE prophylaxis for high risk patients. The use of a preoperative dose of subcutaneous heparin in high-risk pancreatic surgery patients resulted in a statistically significant reduction of VTE events.
