Prescription medication cost, insurance coverage, and cost-related nonadherence among people with spinal cord injury in Canada

Abstract

Study design: Observational cross-sectional study.

Objectives: To describe the most common prescription medications used and the extent of out-of-pocket cost, insurance coverage, and cost-related nonadherence (CRNA) for those medications by people with spinal cord injury (SCI) in Canada.

Setting: Community in Canada.

Methods: It was an observational study wherein data were collected through a cross-sectional online survey from individuals living with an SCI in Canada. We used descriptive statistics to describe the extent of drug cost, insurance coverage and CRNA among study sample, and analytical statistics to find association of CRNA with sociodemographic, injury-related and medication-related characteristics of the sample.

Results: Individuals with an SCI (n = 160) used an average of five medications and spent a median of $49 (interquartile range: $234.75) per month on their medications. More than 90% of participants had some form of drug insurance, though 37% reported CRNA. The most common medications that were forgone due to cost included opioids, antidepressants, and drugs for genitourinary and muscular spasms. Individuals with paraplegia and nontraumatic SCI had higher drug costs, though injury-related characteristics did not influence CRNA. Sex, monthly drug expenditure, and monthly additional healthcare costs were significantly associated with CRNA.

Conclusions: People with SCIs are at risk of experiencing CRNA to their prescription medications despite having insurance coverage. Decision makers for the national pharmacare in Canada should account for their concerns judiciously.
