摘要
Background: The prevalence of present-on-admission pressure injuries (POA-PIs) is much higher than hospitalacquired pressure injuries (HAPIs). But scant attention has been paid to POA-PIs, especially the healing rate and potential prognostic factors. @@@ Objective: To describe the characteristics of POA-PIs at admission and the outcomes of POA-PIs at discharge, and to explore potential prognostic factors of POA-PIs wound healing. @@@ Methods: This study analyzed electronic health records (EHRs) for 838 POA-PIs among 586 patients from a Chinese tertiary hospital in 2018. The outcomes of POA-PIs were identified into four categories by comparing POA-PIs' wound area and exudation amount scores at admission and discharge: deteriorating, stable, improving, and healed. The generalized estimating equation (GEE) was carried out to screen the prognostic factors of POAPIs wound healing. @@@ Results: Among this population, 66.38% of the patients were male, 44.03% patients had a Braden Score less than 12 and the median of the Charlson comorbidity index was 5. The most common location of POA-PI wounds was the sacrum and the most common stage of them was Stage II. Nearly half of wounds (45.78%) were larger than 15 cm(2), 26.61% were deeper than 0.5 cm, and 61.81% of the wounds were painful. When the patients were discharged, 29.71% wounds were healed, 36.16% were in improving status, 25.78% kept stable, and 8.35% wounds were in deteriorating status. Wound depth was the only independent prognostic factor for POA-PIs wound healing. @@@ Conclusions: The healing rate of POA-PIs is quite low, and the only independent prognostic factor of POA-PIs was wound depth.
