Abstract

BACKGROUND

This study aimed to assess inpatient prevalence, characteristics, outcomes, and resource utilization of hospitalization for heat stroke in the United States. Additionally, this study aimed to explore factors associated with in-hospital mortalities of heat stroke.

METHODS

The 2003-2014 National Inpatient Sample database was used to identify hospitalized patients with a principal diagnosis of heat stroke. The inpatient prevalence, clinical characteristics, in-hospital treatments, outcomes, length of hospital stay, and hospitalization cost were studied. Multivariable logistic regression was performed to identify independent factors associated with in-hospital mortality.

RESULTS

A total of 3,372 patients were primarily admitted for heat stroke, accounting for an overall inpatient prevalence of heat stroke among hospitalized patients of 36.3 cases per 1,000,000 admissions in the United States with an increasing trend during the study period (p<0.001). Age 40-59 was the most prevalent age group. During hospital stay, 20% required mechanical ventilation, and 2% received renal replacement therapy. Rhabdomyolysis was the most common complication. Renal failure was the most common end-organ failure, followed by neurological, respiratory, metabolic, hematologic, circulatory, and liver systems. The in-hospital mortality rate of heat stroke hospitalization was 5% with a decreasing trend during the study period (p<0.001). The presence of end-organ failure was associated with increased in-hospital mortality, whereas more recent year of hospitalization was associated with decreased in-hospital mortality. The median length of hospital stay was 2 days. The median hospitalization cost was $17372.

CONCLUSION

The inpatient prevalence of heat stroke in the United States increased, while the in-hospital mortality of heat stroke decreased.
