Aim: Multiple risk factors are involved in geriatric syndrome (GS) occurring in older adults. Although drug therapy often contributes to GS, the specific causes among older adults in Japan remain unclear. In this study, we examined the possible prescribing cascade rate among older outpatients eligible for Late-stage Elderly Health Insurance and elucidated the differences between GS and GS associated with medication (GSAM) trends. Methods: This retrospective study enrolled patients from health insurance claims data in Japan between October 2018 and March 2019; hospitalized patients were excluded. Two groups were identified among the participants with GS: GS (no use of GS-causing medications) and possible-GSAM (p-GSAM; use of GS-causing medications). The collected data were analyzed using the Bell Curve for Excel, and statistical significance was set at P < 0.05. Results: In total, 137 781 outpatients were enrolled. Of the 32 259 outpatients who did not use GS-causing medications, 7342 were classified into the GS group. Among 105 522 outpatients who used GS-causing medications, 8347 were classified as having p-GSAM. The mean number of prescriptions was significantly higher in the p-GSAM group than in the GS group (P < 0.01). Furthermore, all GS symptoms showed significant differences, with impaired appetite being the most prevalent in the p-GSAM group than in the GS group (P < 0.01). A possible prescribing cascade was suspected in 2826 (33.9%) of 8347 outpatients in the p-GSAM group. Conclusion: Impaired appetite in patients taking GS-causing medications might lead to prescribing cascades. Further studies are needed to prevent such prescribing cascades.
