Increasing Identification and Follow-Up of Older Adult Depression in Primary Care.

INTRODUCTION

Depression is a common mental health disorder faced by older adults that can go undetected and untreated. It was determined that the project site was not screening for depression among their older patient population. Aims: The purpose of this quality improvement project was to determine if the implementation of the Geriatric Depression Scale-15 (GDS-15) would impact the identification of risk factors for depression and follow-up among adults 65 and older.

METHODS

Implementation started in June 2021 in a primary care office in Southern California. Data was collected for this project over a total of 8 weeks. This project was a quality improvement project designed to implement routine depression screening among older adult patients using the GDS-15. Depressive symptoms were identified, and follow-up and treatment for depression in primary care was initiated if indicated by GDS-15 scores. Data were obtained from the project site's electronic medical record on a total sample size of 443 patients (n = 252 in the comparison group and n = 191 in the implementation group).

RESULTS

A chi-square test indicated a clinical and statistically significant improvement in the identification rate of depression, X2 (1, N = 443) = 49.76,  < .0001; and follow-up rate X2 (1, N = 70) = 23.94,  < .0001. Clinical significance was found with an increase in the identification of depression and follow-up of older adults in primary care. Demographic variables were also compared for the QI intervention group patients according to those who scored <5 (n = 134) and patients who scored 5 or greater on the GDS-15 (n = 57) again using chi-square tests. The results showed significant differences between gender ( = .016) and primary diagnosis ( = .006).

CONCLUSIONS

Findings of this project suggest all older adults should receive a depression screening routinely in primary care to increase the recognition of depression as well as follow-up and treatment.
