Supplementary Material for: A Longitudinal Analysis of General Practitioner Service Use by Patients with Mild Cognitive Disorders in Australia

Background: The aim of this study was to ascertain if participants diagnosed with any mild cognitive disorder (MCD) visited a general practitioner (GP) more than those without MCD and the effect of either depression or arthritis on GP use longitudinally.Methods: 2,551 participants aged 60-64 years at baseline completed the Personality and Total Health Through Life (PATH) study in Canberra. Follow-up data were collected after 4 and 8 years. A cognitive screening battery was used to screen participants into a substudy of MCD. Results: Participants with any MCD had greater GP use than cognitively healthy participants across all three waves (wave 1, M = 7.35 vs. 5.59; wave 2, M = 7.77 vs. 5.86; wave 3, M = 9.01 vs. 6.81). After adjusting for demographic and health factors, MCD was a significant predictor of GP use at all three waves (p < 0.05, CI 0.84-0.99). Conclusion: This study has shown that MCD is associated with a higher use of GP visits, especially if the patient has a comorbid condition.
