718 Predictors of Lengthened Admission in Elderly Burn Patients, a Secondary Analysis of 529 Cases
Abstract
Abstract Introduction Existing research has examined the relationship between the amount of total body surface area (TBSA) burn and length of stay (LOS) for older adults. As a result, the conventional ratio of 1 day LOS/1% TBSA ratio has been updated to 2 days LOS/1% TBSA. In this study, we aim to elucidate patient and injury characteristics that affect our prognostic indicator, leading to a prolonged LOS. Methods This was a secondary analysis of a cohort study of surviving patients admitted to a tertiary adult burn center between January 1, 2006, and June 30, 2021. Older adult patients aged 60 and over were stratified into expected LOS (2.0 days/%TBSA). Patient demographics, TBSA, inhalation injury, pre-admission co-morbidities, and in-hospital complications were tabulated. Logistic regressions were performed using IBM SPSS Statistics 29 and Stata Statistical Software: Release 18. Results 529 patients with a mean age of 71 years were included for analysis of the older adult population. 266 patients had the expected LOS/TBSA ratio, and 263 exceeded this ratio. Univariable analysis indicated patients with greater age [1.03 (1.01 – 1.05) p = 0.002], hypertension [1.72 (1.22 – 2.42) p = 0.002], diabetes [1.95 (1.30 – 2.93) p = 0.001], respiratory disease [2.22 (1.40 – 3.53) p = 0.001], cardiac disease [1.75 (1.24 – 2.47) p = 0.002], psychiatric illness [1.75 (1.04 – 2.96) p = 0.035], and those who experienced complications (such as infection, graft failure, pneumonia, sepsis)…
How strong is the evidence?
Evidence Hub reads this as a secondary / pooled analysis, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 529 participants or records.
