Cost of Illness of Pressure Injuries in the Inpatient Area of a Socio-Health Center in Spain

Abstract

Objective: To estimate the increase in length of stay and cost of illness of pressure injuries (PIs) in the inpatient area of a socio-health center.

Methods: This was a retrospective cohort study that included a consecutive sampling of patients admitted to the inpatient programs of a socio-healthcare center between January 1, 2016, and December 31, 2018. Data were retrospectively extracted from patients' electronic health records.

Results: During the study period 4,062 patients were admitted to the different hospitalization programs. The patients' mean age was 75.34 ± 13.69 years, and 51.2% of them were men. Of these, 1,421 patients had PIs, and 318 patients had to prolong their hospital stay due to PIs. These 318 patients were admitted 12,089 days longer (mean of 38.01 ± 41.49 days per patient) than patients without a PI, representing an expense of €1,381,006 (US $1,430,722). The cost of illness in the period under study was estimated at €1,922,049 (US $1,991,212). The average cost of PI treatment per patient was €1,352.60 ± €3,351.43 (US $1,401.29 ± $3,472.08), and the average cost of treatment until complete resolution of a PI was €2,064.65 ± €4,282.48 (US $1,470.79 ± $4,436.65). The cost of treatment ranged from €1,419.68 ± €3,100.47 (US $2,138.98 ± $3,212.09) for stage 1 PIs to €6,299.31 ± €10,000.57 (US $6,526.08 ± $10,360.59) for stage 4 PIs.

Conclusions: This study highlights the significant health and economic impacts of PIs in the inpatient area of a socio-health center. The findings emphasize the necessity of effective prevention strategies to mitigate the occurrence of PIs and their associated costs. By understanding the financial burden of PIs, healthcare providers and policymakers can make informed decisions to improve resource allocation, enhance patient care, and reduce financial strain on the healthcare system.
