Epidemiology, Characteristics, and Outcomes of ICU-Managed Homeless Patients: A Population-Based Study

Background. The population-level demand for critical care services among the homeless (H) remains unknown, with only sparse data on the characteristics and outcomes of those managed in the ICU. Methods. The Texas Inpatient Public Use Data File and annual federal reports were used to identify H hospitalizations and annual estimates of the H population between 2007 and 2014. The incidence of ICU admissions in the H population, the characteristics of ICU-managed H, and factors associated with their short-term mortality were examined. Results. Among 52,206 H hospitalizations 15,553 (29.8%) were admitted to ICU. The incidence of ICU admission among state H population rose between 2007 and 2014 from 28.0 to 96.6/1,000 (p<0.0001), respectively. Adults aged ≥ 45 years and minorities accounted for 70.2% and 57.6%, respectively, of the growth in volume of ICU admissions. Short-term mortality was 3.2%, with odds of death increased with age, comorbidity burden, and number of failing organs. Conclusions. The demand for critical care services was increasingly high among the H and was contrasted by low short-term mortality among ICU admissions. These findings, coupled with the persistent health disparities among minority H, underscore the need to effectively address homelessness and reduce barriers to longitudinal appropriate prehospital care among the H.

Abstract Background Sepsis is the most common cause of premature death among patients with systemic lupus erythematosus (SLE) aged ≤ 50 years in the United States, and infection is the most common cause of admission to the ICU among SLE patients. However, there are no population-level data on the patterns of the demand for critical care services among hospitalized septic patients with SLE or the outcomes of those admitted to the ICU. Methods We performed a retrospective cohort study, using the Texas Inpatient Public Use Data File, to identify SLE hospitalizations aged ≥ 18 years and the subgroups with sepsis and ICU admission during 2009–2014. The patterns of ICU admission among septic hospitalizations were examined. Logistic regression modeling was used to identify predictors of short-term mortality (defined as hospital death or discharge to hospice) among ICU admissions with sepsis and to estimate the risk-adjusted short-term mortality among ICU admissions with and without sepsis. Results Among 94,338 SLE hospitalizations, 17,037 (18.1%) had sepsis and 9409 (55.2%) of the latter were admitted to the ICU. Sepsis accounted for 51.5% of the growth in volume of ICU admissions among SLE hospitalizations during the study period. Among ICU admissions with sepsis, 25.3% were aged ≥ 65 years, 88.6% were female, and 64.4% were non-white minorities. The odds of short-term mortality among septic ICU admissions were increased among those lacking health insurance (adjusted odds ratio 1.40 [95% confidence interval 1.07–1.84]), while being unaffected by gender and race/ethnicity, and remaining unchanged over the study period. On adjusted analyses among ICU admissions, the short-term mortality among those with and without sepsis was 13% (95% CI 12.6–13.3) and 2.7% (95% CI 2.6–2.8), respectively. Sepsis was associated with 63.6% of all short-term mortality events. Conclusions Sepsis is a major, incremental driver of the demand for critical care services among SLE hospitalizations. Despite its relatively low mortality, sepsis was associated with most of the short-term deaths among ICU patients with SLE.

Short Term Mortality

Objective: Patients experiencing signs and symptoms of an acute myocardial infarction (AMI) require prompt evaluation and treatment. There are little contemporary data, however, available on how the extent of delay between the onset of acute coronary symptoms and hospital presentation may impact short-term mortality. The purpose of this population-based study was to examine the relationship between extent of pre-hospital delay with hospital case-fatality rates (HCFRs) and 30-day post-admission mortality rates (PAMRs) among patients hospitalized with validated AMI in all central Massachusetts medical centers, and trends over time therein. Methods: We examined the medical records of residents of the Worcester, MA, metropolitan area hospitalized with a confirmed AMI at all 11 central MA medical centers on a biennial basis between 1999 and 2009 (n = 6,017). Information on patient’s demographic, medical history, clinical characteristics, and time of acute symptom onset and hospital arrival was abstracted. Results: Hospital medical record data on pre-hospital delay were available for 2,913 (48%) subjects of whom their mean age was 68 years, 38% were female, and 90% were Caucasian. The mean and median pre-hospital delay times were 4.0 hours and 2.0 hours, respectively, with little change noted in these times between 1999 and 2009. Patients who reported pre-hospital delay times greater than two hours were more likely to be older, female, and have a history of heart failure or diabetes mellitus as compared with patients who delayed seeking medical care by less than 2 hours. The overall HCFR was 6.6% and 30-day PAMR was 9.4%. The average HCFRs and 30-day PAMRs varied slightly between those with delay times of less than 2 hours (6.5%, 9.2%), 2 to 4 hours (6.3%, 8.6%), and greater than 4 hours (7.0%, 10.6%). No statistically significant changes in HCFRs and 30-day PAMRs were observed as pre-hospital delay times increased. Analyses of our principal study outcomes according to type of AMI (e.g., STEMI and NSTEMI) are ongoing and will be presented subsequently. Conclusions: This population-based study of residents of central MA hospitalized with AMI in all metropolitan Worcester medical centers showed little change in average and median pre-hospital delays between 1999 and 2009. Both the HCFRs and 30-day PAMRs were not significantly increased with greater durations of pre-hospital delay possibly due to potential confounders such as symptom severity. Our preliminary results suggest the need to further investigate trends in pre-hospital delay and short-term mortality, including patients who die in the community before receiving acute medical care.
