Impact of Hurricane Harvey on Healthcare Utilization and Emergency Department Operations.

ABSTRACT: INTRODUCTION:Hurricanes have increased in severity over the past 35 years, and climate change has led to an increased frequency of catastrophic flooding. The impact of floods on emergency department (ED) operations and patient health has not been well studied. We sought to detail challenges and lessons learned from the severe weather event caused by Hurricane Harvey in Houston, Texas, in August 2017. METHODS:This report combines narrative data from interviews with retrospective data on patient volumes, mode of arrival, and ED lengths of stay (LOS). We compared the five-week peri-storm period for the 2017 hurricane to similar periods in 2015 and 2016. RESULTS:For five days, flooding limited access to the hospital, with a consequent negative impact on provider staffing availability, disposition and transfer processes, and resource consumption. Interruption of patient transfer capabilities threatened patient safety, but flexibility of operations prevented poor outcomes. The total ED patient census for the study period decreased in 2017 (7062 patients) compared to 2015 (7665 patients) and 2016 (7770) patients). Over the five-week study period, the arrival-by-ambulance rate was 12.45% in 2017 compared to 10.1% in 2016 (p < 0.0001) and 13.7% in 2015 (p < 0.0001). The median ED length of stay (LOS) in minutes for admitted patients was 976 minutes in 2015 (p < 0.0001) compared to 723 minutes in 2016 and 591 in 2017 (p < 0.0001). For discharged patients, median ED LOS was 336 minutes in 2016 compared to 356 in 2015 (p < 0.0001) and 261 in 2017 (p < 0.0001). Median boarding time for admitted ED patients was 284 minutes in 2016 compared to 470 in 2015 (p < 0.0001) and 234.5 in 2017 (p < 0.001). Water damage resulted in a loss of 133 of 179 inpatient beds (74%). Rapid and dynamic ED process changes were made to share ED beds with admitted patients and to maximize transfers post-flooding to decrease ED boarding times. CONCLUSION:A number of pre-storm preparations could have allowed for smoother and safer ride-out functioning for both hospital personnel and patients. These measures include surplus provisioning of staff and supplies to account for limited facility access. During a disaster, innovative flexibility of both ED and hospital operations may be critical when disposition and transfer capibilities or bedding capacity are compromised.

Project description:OBJECTIVE:To evaluate the association between Hurricane Harvey landfall with maternal and neonatal morbidity. METHODS:Using an institutional perinatal database from two hospitals in Houston, Texas, women with nonanomalous singletons delivering after 24 weeks of gestation between August 2011 and June 2018 were included. To evaluate the possible association of hurricane landfall with pregnancy outcomes, gravid women delivering within 280 days (40 weeks of gestation) on or after August 25, 2017 (the day of hurricane landfall) were categorized as exposed, and women who delivered before August 25, 2017, were the reference group. Composite maternal morbidity included any of the following: hypertensive disorders of pregnancy, chorioamnionitis, endometritis, blood transfusion, peripartum hysterectomy, maternal critical care admission, pulmonary edema, or maternal death. Composite neonatal morbidity included any of the following: 5-minute Apgar score 3 or less, respiratory distress syndrome, use of ventilator or continuous positive airway pressure, suspected newborn sepsis, seizure, stillbirth, or neonatal death. Adjusted odds ratios (aORs) were calculated after correcting for possible confounders identified on univariate analysis. Disruption in outcome trends were measured in time series analyses. RESULTS:Of 40,502 deliveries in our database, 29,179 (72%) met the inclusion criteria, with 3,842 (13.2%) delivering within 280 days of Hurricane Harvey landfall. Women delivering after Hurricane Harvey were on average less likely to be obese and more likely to be older, Caucasian, married, have a household income higher than $75,000, a high school education, and private insurance. However, compared with the cohort of gravid patients who delivered before Hurricane Harvey, composite maternal morbidity increased by 27% (11.5% vs 14.7%, aOR 1.27, 95% CI 1.14-1.42) after the storm. Composite neonatal morbidity increased by 50% (7.8% vs 11.9%, aOR 1.52, 95% CI 1.34-1.71). In time series analyses, we observed a significant shift in composite maternal morbidity specific to women of low socioeconomic status (estimate 2.87, P=.028). CONCLUSION:Despite having fewer at-risk baseline characteristics, gravid patients delivering after landfall by Hurricane Harvey had a significantly higher likelihood of adverse outcomes as did their neonates.

Project description:ImportanceHurricanes and flooding can interrupt health care utilization. Understanding the magnitude and duration of interruptions, as well as how they vary according to hazard exposure, race, and income, are important for identifying populations in need of greater retention in care.ObjectiveTo determine how the differential exposure to Hurricane Harvey in August 2017 is associated with changes in utilization of Veterans Health Administration health care.Design, setting, and participantsThis is a retrospective cohort analysis of primary care practitioner (PCP) visits, emergency department visits, and inpatient admissions in the Veterans Health Administration among Texas veterans residing in counties impacted by Hurricane Harvey from 2016 to 2018. Data analysis was performed from September 2020 to May 2021.ExposuresResidential flooding after Hurricane Harvey.Main outcomes and measuresInterrupted time series analysis measured changes in health care utilization over time, stratified by residential flood exposure, race, and income.ResultsOf the 99 858 patients in the cohort, 89 931 (90.06%) were male, and their median (range) age was 58 (21 to 102) years. Compared with veterans in nonflooded areas, veterans living in flooded areas were more likely to be Black (24 715 veterans [33.80%] vs 4237 veterans [15.85%]) and low-income (14 895 veterans [20.37%] vs 4853 veterans [18.15%]). Rates of PCP visits decreased by 49.78% (95% CI, -64.52% to -35.15%) for veterans in flooded areas and by 45.89% (95% CI, -61.93% to -29.91%) for veterans in nonflooded areas and did not rebound until more than 8 weeks after the hurricane. Rates of PCP visits in flooded areas remained lower than expected for 11 weeks among White veterans (-6.99%; 95% CI, -14.36% to 0.81%) and for 13 weeks among racial minority veterans (-7.22%; 95% CI, -14.11% to 0.30%). Low-income veterans, regardless of flood status, experienced greater suppression of PCP visits in the 8 weeks following the hurricane (-13.72%; 95% CI, -20.51% to -6.68%) compared with their wealthier counterparts (-9.63%; 95% CI, -16.74% to -2.26%).Conclusions and relevanceThese findings suggest that flood disasters such as Hurricane Harvey may be associated with declines in health care utilization that differ according to flood status, race, and income strata. Patients most exposed to the disaster also had the greatest delay or nonreceipt of care.
