Background
Most adults with neurological disability rely on general practitioners for the management and early intervention of health needs. Understanding the frequency and patterns of service use across neurological disability subgroups is vital to inform effective practice and policy initiatives. This study analysed the patterns of general practice service utilisation of National Disability Insurance Scheme (NDIS) participants with Acquired Brain Injury, Cerebral Palsy, Multiple Sclerosis, Spinal Cord Injury, and Stroke and compared these patterns with those of the rest of the population.
Methods
This is a retrospective data linkage study using de-identified general practice electronic medical records from Victoria, Australia that have been linked with de-identified NDIS data. Patient records span July 2017 to February, 2023. To gain insight into patients’ utilisation of general practice services, we looked at: 1) frequency of clinic activities and general practitioner activities, 2) number of different general practice clinics visited and 3) number of distinct general practitioners seen.
Results
The study sample comprised 818,456 adult patients (2,104 NDIS participants with neurological disability; 816,352 rest of population). Our results indicate a consistent pattern of high general practice service utilisation among adults with neurological disabilities wherein service utilisation rates of all investigated neurological disability cohorts were approximately 2 times higher than rates found in the rest of the population (incidence rate ratio (IRR) 1.84 to 2.12, confidence interval (CI) range [1.84 to 2.33]). In further comparison to the rest of the population, a slightly lower rate of accessing different general practice clinics was found for participants with Cerebral Palsy (IRR = 0.85, CI [0.80, 0.90]). However, results suggest that adults with neurological disability consult multiple general practitioners and visit different clinics over available record years.
Conclusions
Findings from this administrative health data provides a valuable foundation and demonstrates that adults with neurological disability in Australia use general practice services more frequently than the rest of the population. Investigating the factors that influence general practice service utilization, as well as the quality of consultations and continuity of care experienced by adults with neurological disability, remains a critical area for future research.
