Risk of Hospital-Acquired Sacral Pressure Injuries in COVID-19 Patients

Patients who are hospitalized with COVID-19 (COVID-19(+)) are at an increased risk of hospital-acquired sacral pressure injuries (HASPIs), compared with patients who are hospitalized without COVID-19. (COVID-19(-)).¹ Further, COVID-19(+) patients with HASPIs have higher stage ulcerations than COVID-19(-) patients. In a retrospective study of 58,766 hospitalized patients who spent ≥ 5 days at Cleveland Clinic from March 1, 2020─December 31, 2020, 293 developed HASPI. When controlling for Braden risk at admission, age, length of stay, medical comorbidities, intensive care unit admission, and need for ventilation, COVID-19(+) patients had 40% increased odds of developing a HASPI compared with COVID-19(-) patients (P = 0.03) and were more likely to develop a HASPI of severe stage (P = 0.001). Additionally, COVID-19(+) patients with HASPIs had 2.2x odds of a more severe hospitalization course compared with COVID-19(+) patients without HASPIs (P < 0.001). When comparing histologic features of biopsies/debridement tissue related to HASPIs, tissue from COVID-19(+) patients (N = 4) had 3x the number of thromboses in dermal vessels compared with tissue from COVID-19(-) patients (N = 2).

These findings support the observation that the skin may sustain significant damage secondary to COVID-19.²⁻⁴ These injuries may contribute to significant future morbidity, healthcare expenditure, and even mortality in patients who recover from COVID-19.⁵⁻⁶ Histopathologic analysis suggests thrombotic vasculopathy in areas of pressure may play a role in COVID-19-associated HASPI development.

HASPI = Hospital-acquired sacral pressure injury. Bolded values denote statistically significant P-values.

P-values are representative of 5 different multivariable regression analysis all controlling for Braden ulcer risk at admission, medical comorbidities (hypertension, congestive heart failure, chronic obstructive pulmonary disease, and diabetes mellitus), age at admission, length of hospital stay, requirement for ICU admission, and requirement for intubation with COVID-19 status (positive vs. negative) as the predictor variable.

P-value based on odds ratio from multivariable logistic regression results.

P-value based on hazard ratio from multivariable Cox proportional hazards model.

P-value based on odds ratio from multivariable ordinal regression.

P-value based on parameter estimate from multivariable linear regression.
