BACKGROUND: Acute flaccid myelitis (AFM) is a severe illness similar to paralytic poliomyelitis. It is unclear how frequently AFM occurred in U.S. children after poliovirus elimination. In 2014, an AFM cluster was identified in Colorado, prompting passive US surveillance that yielded 120 AFM cases of unconfirmed etiology. Subsequently, increased reports were received in 2016 and 2018. To help inform investigations on causality of the recent AFM outbreaks, our objective was to determine how frequently AFM had occurred before 2014, and if 2014 cases had different characteristics.

METHODS: We conducted a retrospective study covering 2005-2014 at 5 pediatric centers in 3 …

Multiple Regression Models To Analyze Length Of Hospitalization Due To Nosocomial Infections In U.S. Hospitals, Ernest M. Oleksy

The Downtown Review

Nosocomial diseases are a serious concern and detriment to hospitals’ abilities to provide appropriate patient care. Bearing this in mind, an effort must be made to determine whether infection surveillance and control programs have reduced the rates of nosocomial infection at U.S. hospitals. The data that were studied were obtained as part of the Study on the Efficacy of Nosocomial Infection Control (SENIC) and used to develop a model of what variables most contribute to a patient’s length of stay at the Cleveland Clinic (Quade et al, 1980).

Racial/Ethnic Disparities In Infectious Disease Hospitalizations In Arizona, Laura Callinan, Robert Holman, Douglas Esposito, Marian Mcdonald

Journal of Health Disparities Research and Practice

Infectious disease (ID) hospitalizations in Arizona, a diverse population with nearly complete race/ethnicity data, were analyzed using the State Inpatient Database for 2005-2008. ID hospitalizations rates were calculated and compared by ID group, race/ethnicity, age, and sex. During 2005-2008, there were 383,597 ID hospitalizations reported in Arizona, resulting in an age-adjusted rate of 1498.1 per 100,000 persons. A range of racial/ethnic disparities in ID hospitalization rates were noted. Persons of Native American and black race/ethnicity had overall ID hospitalization rates higher than the rate for persons of white race/ethnicity; persons of Asian or Pacific Islander race/ethnicity had a lower rate. …

The objectives of this study were to describe contemporary postdischarge death rates of patients hospitalized at all Worcester, Massachusetts, hospitals after initial acute myocardial infarctions (AMIs) and to examine factors associated with a poor prognosis. The medical records of patients discharged from 11 central Massachusetts medical centers after initial AMIs during 2001, 2003, 2005, and 2007 were reviewed, identifying 2,452 patients. This population was composed of predominantly older patients, men (58%), and whites. Overall, the 3-month, 1-year, and 2-year all-cause death rates were 8.9%, 16.4%, and 23.4%, respectively. Over time, reductions in postdischarge mortality were observed in crude as well …

Six-Month Mortality And Cardiac Catheterization In Non-St-Segment Elevation Myocardial Infarction Patients With Anemia, Wen-Chih Wu, Molly Waring, Darleen Lessard, Jorge Yarzebski, Joel Gore, Robert Goldberg

Jorge L. Yarzebski

BACKGROUND: It is unknown how anemia influences the invasive management of patients with non-ST-segment elevation myocardial infarction (NSTEMI) and associated mortality. We investigated whether receipt of cardiac catheterization relates to 6-month death rates among patients with different severity of anemia. METHODS: We used data from the population-based Worcester Heart Attack Study, which included 2634 patients hospitalized with confirmed NSTEMI, from three percutaneous coronary intervention-capable medical centers in the Worcester (Massachusetts, U.S.A.) metropolitan area, during five biennial periods between 1997 and 2005. Severity of anemia was categorized using admission hematocrit levels: less than or equal to 30.0% (moderate-to-severe anemia), 30.1-39.0% (mild …
