Background: The long-term prognosis of spontaneous intracerebral hemorrhage (SICH) is poor. Frequent emergency department (ED) visits can signal increased risk of hospitalization and death. There are no studies describing the risk of frequent ED visits after SICH. Methods: Retrospective cohort study of a community representative consecutive SICH survivors (2009-2015) from southern Portugal. Logistic regression analysis was performed to identify sociodemographic and clinical factors associated with frequent ED visits (≥4 visits) within the first year after hospital discharge. Results: A total of 360 SICH survivors were identified, 358 (98.6%) of whom were followed. The median age was 72; 64% were males. The majority of survivors (n = 194, 54.2%) had at least 1 ED visit. Reasons for ED visits included infections, falls with trauma, and isolated neurological symptoms. Forty-four (12.3%) SICH survivors became frequent ED visitors. Frequent ED visitors were older and had more hospitalizations ( P < .001) and ED visits ( P < .001) prior to the SICH, unhealthy alcohol use ( P = .049), longer period of index SICH hospitalization ( P = .032), pneumonia during hospitalization ( P = .001), and severe neurological impairment at discharge ( P = .001). Pneumonia during index hospitalization (odds ratio [OR]: 3.08; confidence interval [CI]: 1.39-6.76; P = .005) and history of ED visits prior to SICH (OR: 1.64; CI: 1.19-2.26, P = .003) increased the likelihood of becoming a frequent ED visitor. Conclusions: Predictors of frequent ED visits are identifiable at hospital discharge and during any ED visit. Improvement of transitional care and identification of at-risk patients may help reduce multiple ED visits.

Background As the global climate changes in response to anthropogenic greenhouse gas emissions, weather and temperature are expected to become increasingly variable. Although heat sensitivity is a recognized clinical feature of multiple sclerosis (MS), a chronic demyelinating disorder of the central nervous system, few studies have examined the implications of climate change for patients with this disease. Methods and findings We conducted a retrospective cohort study of individuals with MS ages 18–64 years in a nationwide United States patient-level commercial and Medicare Advantage claims database from 2003 to 2017. We defined anomalously warm weather as any month in which local average temperatures exceeded the long-term average by ≥1.5°C. We estimated the association between anomalously warm weather and MS-related inpatient, outpatient, and emergency department visits using generalized log-linear models. From 75,395,334 individuals, we identified 106,225 with MS. The majority were women (76.6%) aged 36–55 years (59.0%). Anomalously warm weather was associated with increased risk for emergency department visits (risk ratio [RR] = 1.043, 95% CI: 1.025–1.063) and inpatient visits (RR = 1.032, 95% CI: 1.010–1.054). There was limited evidence of an association between anomalously warm weather and MS-related outpatient visits (RR = 1.010, 95% CI: 1.005–1.015). Estimates were similar for men and women, strongest among older individuals, and exhibited substantial variation by season, region, and climate zone. Limitations of the present study include the absence of key individual-level measures of socioeconomic position (i.e., race/ethnicity, occupational status, and housing quality) that may determine where individuals live—and therefore the extent of their exposure to anomalously warm weather—as well as their propensity to seek treatment for neurologic symptoms. Conclusions Our findings suggest that as global temperatures rise, individuals with MS may represent a particularly susceptible subpopulation, a finding with implications for both healthcare providers and systems.

Background Critical care patients with delirium are at an increased risk of functional decline and mortality long term. Objective To determine the relationship between delirium severity in the intensive care unit and mortality and acute health care utilization within 2 years after hospital discharge. Methods A secondary data analysis of the Pharmacological Management of Delirium and Deprescribe randomized controlled trials. Patients were assessed twice daily for delirium or coma using the Richmond Agitation-Sedation Scale and the Confusion Assessment Method for the Intensive Care Unit (CAM-ICU). Delirium severity was measured using the CAM-ICU-7. Mean delirium severity (from time of randomization to discharge) was categorized as rapidly resolving, mild to moderate, or severe. Cox proportional hazards regression was used to model time to death, first emergency department visit, and rehospitalization. Analyses were adjusted for age, sex, race, Charlson Comorbidity Index, Acute Physiology and Chronic Health Evaluation II score, discharge location, diagnosis, and intensive care unit type. Results Of 434 patients, those with severe delirium had higher mortality risk than those with rapidly resolving delirium (hazard ratio 2.21; 95% CI, 1.35-3.61). Those with 5 or more days of delirium or coma had higher mortality risk than those with less than 5 days (hazard ratio 1.52; 95% CI, 1.07-2.17). Delirium severity and number of days of delirium or coma were not associated with time to emergency department visits and rehospitalizations. Conclusion Increased delirium severity and days of delirium or coma are associated with higher mortality risk 2 years after discharge.

Outbreak Investigations

Recent outbreak investigations suggest that a substantial proportion of waterborne disease outbreaks are attributable to water distribution system issues. In this analysis, we examine the relationship between modeled water residence time (WRT), a proxy for probability of microorganism intrusion into the distribution system, and emergency department visits for gastrointestinal (GI) illness for two water utilities in Metro Atlanta, USA during 1993–2004. We also examine the association between proximity to the nearest distribution system node, based on patients' residential address, and GI illness using logistic regression models. Comparing long (≥90th percentile) with intermediate WRTs (11th to 89th percentile), we observed a modestly increased risk for GI illness for Utility 1 (OR = 1.07, 95% CI: 1.02–1.13), which had substantially higher average WRT than Utility 2, for which we found no increased risk (OR = 0.98, 95% CI: 0.94–1.02). Examining finer, 12-hour increments of WRT, we found that exposures &gt;48 h were associated with increased risk of GI illness, and exposures of &gt;96 h had the strongest associations, although none of these associations was statistically significant. Our results suggest that utilities might consider reducing WRTs to &lt;2–3 days or adding booster disinfection in areas with longer WRT, to minimize risk of GI illness from water consumption.

Zip Code

We examined whether the average water residence time, the time it takes water to travel from the treatment plant to the user, for a zip code was related to the proportion of emergency department (ED) visits for gastrointestinal (GI) illness among residents of that zip code. Individual-level ED data were collected from all hospitals located in the five-county metro Atlanta area from 1993 to 2004. Two of the largest water utilities in the area, together serving 1.7 million people, were considered. People served by these utilities had almost 3 million total ED visits, 164,937 of them for GI illness. The relationship between water residence time and risk for GI illness was assessed using logistic regression, controlling for potential confounding factors, including patient age and markers of socioeconomic status (SES). We observed a modestly increased risk for GI illness for residents of zip codes with the longest water residence times compared with intermediate residence times (odds ratio (OR) for Utility 1 = 1.07, 95% confidence interval (CI)=1.03, 1.10; OR for Utility 2 = 1.05, 95% CI = 1.02, 1.08). The results suggest that drinking water contamination in the distribution system may contribute to the burden of endemic GI illness.

Abstract Background Understanding the health effects of smoke from landscape fires (LFs), including wildfires and prescribed burns, is limited due to lack of adequate smoke exposure measures. Methods We used the reported LFs to determine smoke plume shapes from satellite images. Daily remotely sensed fire radiative power, aerosol optical depth, smoke plumes, fire danger rating, venting index and previous day PM 2.5 were then used to estimate smoke-related particulate matter 2.5 (PM2.5). A population based time series design was used to assess associations between smoke-related PM2.5 and selected adverse health outcomes such as hospital admissions, emergency department visits and ambulance callouts. Results We found a significant dose-response relationship between increased smoke-related PM2.5 concentration and 1% to 5% increase for total emergency department attendances and total hospital admissions on the same day and the lag effects of 3 days where the PM2.5 was at medium level (95-98th percentile) and high level ( &gt; =99th percentile) compared to the low level (&lt;95th percentile). There was also 1% to 25% increased risk for individuals who were exposed to high level LF smoke with selected respiratory and cardiovascular diseases in selected health care utilisations. Conclusions Exposure to LF smoke at a high level was spatio-temporally associated with a wide range of adverse respiratory and cardiovascular diseases in selected health care utilisations.

Increased Risk

Wildfires are increasing in frequency, size, and intensity, and increasingly affect highly populated areas. Wildfire smoke impacts cardiorespiratory health; children are at increased risk due to smaller airways, a higher metabolic rate and ongoing development. The objective of this systematic review was to describe the risk of pediatric respiratory symptoms and healthcare visits following exposure to wildfire smoke. Medical and scientific databases and the grey literature were searched from inception until December 2020. Included studies evaluated pediatric respiratory-related healthcare visits or symptoms associated with wildfire smoke exposure. Prescribed burns, non-respiratory symptoms and non-pediatric studies were excluded. Risk of bias was evaluated using the National Toxicology Program’s Office of Health Assessment and Translation Risk of Bias Rating Tool. Data are presented narratively due to study heterogeneity. Of 2138 results, 1167 titles and abstracts were screened after duplicate removal; 65 full text screens identified 5 pre-post and 11 cross-sectional studies of rural, urban and mixed sites from the USA, Australia, Canada and Spain. There is a significant increase in respiratory emergency department visits and asthma hospitalizations within the first 3 days of exposure to wildfire smoke, particularly in children < 5 years old.

Abstract Background Immunocompromised adults are at .increased risk of herpes zoster (HZ) infection and related complications. We aimed to assess the incidence of hospital-attended HZ (ie, seen in hospital or emergency department) in immunocompromised populations and compare it to immunocompetent populations. Methods We calculated incidence rates (IRs) of hospital-attended HZ in Ontario, Canada, between 1 April 2002 and 31 August 2016 in adults ≥18 years of age categorized as immunocompromised or immunocompetent. We repeated these analyses by type of immunocompromising condition and provided incidence rate ratios (IRRs) comparing to immunocompetent adults. We also calculated IRs and IRRs of HZ complications by immunocompromised status. Results There were 135 206 incident cases of hospital-attended HZ during the study period. Immunocompromised adults accounted for 13% of these cases despite representing 3% of the population. The risk of hospital-attended HZ was higher for immunocompromised adults compared with immunocompetent adults (IRR, 2.9 [95% confidence interval {CI}, 2.9–3.0]) and ranged across type of immunocompromising conditions, from 2.6 (95% CI, 2.6–2.7) in those with a solid tumor malignancy to 12.3 (95% CI, 11.3–13.2) in those who had undergone hematopoietic stem cell transplant. The risk of any HZ complication was higher in immunocompromised adults (IRR, 3.6 [95% CI, 3.5–3.7]) and highest for disseminated zoster (IRR, 32.8 [95% CI, 27.8–38.6]). Conclusions The risk of hospital-attended HZ and related complications was higher in immunocompromised populations compared with immunocompetent populations. Our findings underscore the high-risk nature of this population and the potential benefits that may be realized through HZ vaccination.
