BACKGROUND: Limited information is available about potentially changing and contemporary trends in the incidence and hospital death rates of cardiogenic shock complicating acute myocardial infarction. The objectives of our study were to examine 3-decade-long trends (1975 to 2005) in the incidence rates of cardiogenic shock complicating acute myocardial infarction, patient characteristics and treatment practices associated with this clinical complication, and hospital death rates in residents of a large central New England community hospitalized with acute myocardial infarction at all area medical centers. METHODS AND RESULTS: The study population consisted of 13 663 residents of the Worcester (Mass) metropolitan area hospitalized with acute myocardial infarction at all greater Worcester medical centers during 15 annual periods between 1975 and 2005. Overall, 6.6% of patients developed cardiogenic shock during their index hospitalization. The incidence rates of cardiogenic shock remained stable between 1975 and the late 1990s but declined in an inconsistent manner thereafter. Patients in whom cardiogenic shock developed had a significantly greater risk of dying during hospitalization (65.4%) than those who did not develop cardiogenic shock (10.6%) (PCONCLUSIONS: Our findings indicate improving trends in the hospital prognosis associated with cardiogenic shock. Given the high death rates associated with this clinical complication, monitoring future trends in the incidence and death rates and the factors associated with an increased risk for developing cardiogenic shock remains warranted.Source

Nurse staffing and mortality for Medicare patients with acute myocardial infarctionPerson, Sharina D.; Allison, Jeroan J.; Kiefe, Catarina I.; Weaver, Michael T.; Williams, O. Dale; Centor, Robert M.; Weissman, Norman W. (2004-01-10)CONTEXT: Recent hospital reductions in registered nurses (RNs) for hospital care raise concerns about patient outcomes. OBJECTIVE: Assess the association of nurse staffing with in-hospital mortality for patients with acute myocardial infarction (AMI). DESIGN, SETTING, AND PATIENTS: Medical record review data from the 1994-1995 Cooperative Cardiovascular Project were linked with American Hospital Association data for 118,940 fee-for-service Medicare patients hospitalized with AMI. Staffing levels were represented as nurse to patient ratios categorized into quartiles for RNs and for licensed practical nurses (LPNs). MAIN OUTCOME MEASURES: In-hospital mortality. RESULTS: From highest to lowest quartile of RN staffing, in-hospital mortality was 17.8%, 17.4%, 18.5%, and 20.1%, respectively (P < 0.001 for trend). However, from highest to lowest quartile of LPN staffing, mortality was 20.1%, 18.7%, 17.9%, and 17.2%, respectively P < 0.001). After adjustment for patient demographic and clinical characteristics, treatment, and for hospital volume, technology index, and teaching and urban status, patients treated in environments with higher RN staffing were less likely to die in-hospital; odds ratios (95% confidence intervals) of quartiles 4, 3, and 2 versus quartile 1 were 0.91 (0.86-0.97), 0.94 (0.88-1.00), and 0.96 (0.90-1.02), respectively. Conversely, after adjustment, patients treated in environments with higher LPN staffing were more likely to die in-hospital; odds ratios (95% confidence intervals) of quartiles 4, 3, and 2 versus quartile 1 were 1.07 (1.00-1.15), 1.02 (0.96-1.09), and 1.00 (0.94-1.07), respectively. CONCLUSIONS: Even after extensive adjustment, higher RN staffing levels were associated with lower mortality. Our findings suggest an important effect of nurse staffing on in-hospital mortality.

Clinical and Financial Impact of Hospital Readmissions Following Colorectal Resection: Predictors, Outcomes, and Costs: A ThesisDamle, Rachelle N. (2014-06-25)Background: Following passage of the Affordable Care Act in 2010, 30-day hospital readmissions have come under greater scrutiny. Excess readmissions for certain medical conditions and procedures now result in penalizations on all Medicare reimbursements. We examined the risk factors, outcomes, and costs of 30-day readmissions after colorectal surgery (CRS). Methods: The University HealthSystem Consortium database was queried for adults (≥ 18 years) who underwent colorectal resection for cancer, diverticular disease, inflammatory bowel disease, or benign tumors between January 2008 and December 2011. Our outcomes of interest were readmission within 30-days of the patient’s index discharge, hospital readmission outcomes, and total direct hospital costs. Results: A total of 70,484 patients survived the index hospitalization after CRS during the years under study, 13.7% (9,632) of which were readmitted within 30 days of discharge. The strongest independent predictors of readmission were: LOS ≥4 days (OR 1.44; 95% CI 1.32-1.57), stoma (OR 1.53; 95% CI 1.45-1.61), and discharge to skilled nursing (OR 1.63; 95% CI 1.49-1.76) or rehabilitation facility (OR 2.93; 95% CI 2.54-3.40). Of those readmitted, half occurred within 7 days of the index admission, 13% required ICU care, 6% had a reoperation, and 2% died during the readmission stay. The median combined total direct hospital cost was over twice as high ($26,917 v. $13,817) for readmitted than for nonreadmitted patients. Conclusions: Readmissions following colorectal resection occur frequently and incur a significant financial burden on the healthcare system. Future studies aimed at targeted interventions for high-risk patients may reduce readmissions and curb escalating healthcare costs.

Pilot study of the characteristics of acute stroke events in patients discharged from the Carolina University Hospital, Puerto Rico in 2007Zevallos, Juan Carlos; Gonzalez, Juan; Santiago, Fernando; Rodriguez, Rafael; Rivera, Ada; Garcia, Ana Michelle; Flecha, Felixa; Colon, Marielys; Yarzebski, Jorge L. (2009-09-01)BACKGROUND: Stroke is the third leading cause of death in Puerto Rico. We examined the pre-hospital phase, management and case-fatality-rates (CFR) of patients discharged with acute stroke from the Carolina University of Puerto Rico Hospital during 2007. METHODS: Trained personnel collected information on demographics, delay-time, mode-of-transportation, management, and mortality from all medical records. STATAa was utilized to conduct univariate comparison of demographics, mode-of-transportation, therapeutics and diagnostic characteristics. Logistic regression analysis assessed cohort effect and controlled for confounders. RESULTS: The average age was 69.1 years, and 53% were males. The average delay between onset of symptoms suggestive of stroke and arrival at the emergency department was 4.5 hours. Only 62% of patients utilized Emergency Medical Services (EMS). Intravenous thrombolysis was not administered. Stroke mortality increased with age. Ischemic vs. hemorrhagic CFR was significantly higher (63.9% vs. 36.10%; p = 0.034). CONCLUSIONS: These findings highlight the potential benefit of evidence-based therapeutics and EMS use among stroke patients.
