The 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

OBJECTIVES: To determine whether a health service system is an independent influencing factor of having pressure injury (PI) problems in individuals with chronic spinal cord injury (SCI) living in three countries.

DESIGN: A cross-sectional study.

METHODS: Data from the International Spinal Cord Injury Community Survey (InSCI) were analyzed. The PI 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 SCI 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 PI problems.

RESULTS: Of 790 included participants, 277 (35%) had PI problems. Being recruited from countries with inpatient-oriented SCI specialized systems (Model 1) and visiting rehabilitation medicine/SCI physicians at least once a year (Model 2) is an independent negative correlating factor of PI problems (odds ratio = 0.569 [95%CI: 0.374-0.866] and 0.591 [95%CI: 0.405-0.864], respectively).

CONCLUSION: SCI-specialized health service systems might be a protective factor of PI problems in middle-income country contexts. This result suggests the importance of having SCI-specialized services in middle-income countries to reduce the prevalence of PI problems.
