Community acquired pressure injuries in a work-related spinal cord injury population: Problem characterization and assessment of a working solution

Background: To characterize the problem of community-acquired pressure injuries (CAPIs) in a work-related spinal cord injury (SCI) population in Canada and assess the benefits of a person-centered solution. Characterization of the problem and a solution, albeit in an insured Worker's Compensation Board of British Columbia (WorkSafeBC) cohort, may inform the supply of solutions in the larger SCI population with disparate access to healthcare.

Methods: For this observational study, data on 244 WorkSafeBC clients, who received an intervention featuring pressure injury (PI) assessment between 2011 and 2015, were used to characterize the problem. Data on observed injuries, risk, referrals, and outcomes were linked to healthcare service claims. Employing an activity-based costing methodology, total expenditures on attributed services were calculated for clients with 1 or more PIs. Intervention cost and benefits from the insurer's perspective are considered.

Results: 84 of 244 clients had 1 or more PIs at assessment, with attributed mean cost of $56,092 in 2015 Canadian dollars (CAD). Mean cost by PI severity range from $9580 to $238,736. At an intervention cost of $820,618, detection of less severe injuries provided an opportunity to prevent progression and achieve $3 million in cost avoidance. Follow-up data suggest reasonable returns. Reductions in the incidence, number, and risk of pressure injuries were also observed.

Conclusions: The analysis establishes the cost of CAPIs in a Canadian-based work-related SCI population and suggests preventative and early intervention is not only feasible but also practical. Results are relevant to decisions regarding the use of proactive prevention-based treatment models as opposed to reactive, solutions in the larger SCI population.
