Association Between Health Service Systems and Pressure Injury Problems of Individuals With Chronic Spinal Cord Injury in Malaysia, Indonesia, and Thailand: A Cross-sectional Study

Objective: The aim of the study is to determine whether a health service system is an independent influencing factor of having pressure injury problems in individuals with chronic spinal cord injury living in three countries Design: This is a cross-sectional study. Methods: Data from the International Spinal Cord Injury Community Survey were analyzed. The pressure injury problems were assessed using the Spinal Cord Injury Secondary Condition Scales (dichotomized to “having problem” and “not having problem”). Health service systems were categorized as an inpatient-oriented spinal cord injury–specialized system and a primary care–oriented system. A directed acyclic graph was applied to create a multivariable logistic regression model to determine the independent influencing factors of pressure injury problems. Results: Of 790 included participants, 277 (35%) had pressure injury problems. Being recruited from countries with inpatient-oriented spinal cord injury–specialized systems (model 1) and visiting rehabilitation medicine/spinal cord injury physicians at least once a year (model 2) is an independent negative correlating factor of pressure injury problems (odds ratio = 0.569 [95% confidence interval = 0.374–0.866] and 0.591 [95% confidence interval = 0.405–0.864], respectively). Conclusions: Spinal cord injury–specialized health service systems might be a protective factor of pressure injury problems in middle-income country contexts. This result suggests the importance of having spinal cord injury–specialized services in middle-income countries to reduce the prevalence of pressure injury problems.
