Healthcare utilization and outcomes of spinal cord injured veterans with stage 3–4 pressure injuries

Abstract

Background

Pressure injuries (PI) are a significant source of morbidity for individuals with spinal cord injury/disease (SCI/D). They are also associated with significant healthcare resource utilization including prolonged hospitalizations. However, the long-term outcomes in terms of wound recurrence-free survival, hospital readmission rates, and all-cause mortality in this population remain largely unknown.

Objective

To examine the clinical characteristics, healthcare utilization and outcomes of SCI Veterans hospitalized at the VA North Texas Health Care System (VANTHCS) SCI inpatient unit with stage 3 and 4 PI, and compare these between those who received a myocutaneous flap surgery (flap patients (FP)) and those treated medically (non-flap patients (NFP)).

Methods

A retrospective chart review was conducted of all adult patients admitted to the VANTHCS SCI/D unit with stage 3 or 4 pelvic PI between 1/1/2013 and 12/31/2018. Healthcare utilization and outcome information was extracted for pre-specified time points.

Results

78 patients met criteria (113 hospitalizations; 27 FP; 51 NFP). Average length of stay (LOS) was 122 days; FP had a significantly higher LOS than NFP (P = 0.01). Average number of consults was 24. Estimated cost per hospitalization was $175,198. Readmission rate within 30 days was 12.39%. The mortality rate within 1 year of discharge was 21.57% for NFP, as opposed to 3.70% in the FP group. Only 5.00% of NFP wounds were healed at discharged with sustained healing at 1 year, significantly less than FP wounds (55.26%, P < 0.01).

Conclusions

Despite the high investment in terms of healthcare utilization, outcomes in terms of wound healing are poor. Additionally, nearly 22% of NFP died within one year of discharge. This calls into question the utility of prolonged hospitalizations for PI in the SCI/D population in terms of wound treatment efficacy, healthcare costs, and patient morbidity/mortality.
