Impact of weekend admission on mortality and other outcomes among patients with burn injury: A nationwide analysis
Abstract Objective To study the relationship between day of admission and important outcomes among patients with burn injuries. Methods The 2014 National Inpatient Sample database was used. Inclusion criterion was a principal diagnosis of burn injury. Exclusion criteria were age Results A total of 21,665 patients were included, 29% of whom were admitted on weekends. Weekend admission was an independent predictor of mortality only among patients >65years old (adjusted odds ratio (aOR): 2.66 (1.13–4.51), p=0.02). Although rates of septic shock were similar for both groups (aOR): 1.25 (0.74–2.09, p=0.40), weekends were associated with higher odds of prolonged mechanical ventilation (aOR: 1.28 (1.06–1.55), p=0.01). Time to surgery (adjusted mean difference (amDiff): 0.91 (−0.07 to 1.88) days, p=0.07) and time to P/E-nutrition (amDiff: 0.40 (−3.51 to 4.30) days, p=0.80) were similar for both groups. Finally, LOS was longer for weekend admission (amDiff: 1.36 (0.09–2.63) days, p=0.04), but total charges and costs were similar for both groups (amDiff: $16,268 ($-5093–$37,629), p=0.13 and $3275 ($-2337–$8888), p=0.25). Conclusions Weekend admission is associated with increased mortality among patients with burn injury >65years old. Weekend admission is also associated with increased morbidity and prolonged length of stay. Highlights Weekend admission is associated with higher mortality for patients >65years old. Weekend admission is associated with higher morbidity (prolonged intubation time). Resource utilization is higher for weekend admissions (longer length of hospital stay).
