Feasibility of Goal Attainment Scaling as a patient-reported outcome measure for older patients in primary care

BACKGROUND: Goal Attainment Scaling (GAS) is an outcome measure that reflects the perspectives and experiences of patients, consistent with patient-centred care approaches and with the aims of patient-reported outcome measures (PROMs). GAS has been used in a variety of clinical settings, including in geriatric care, but research on its feasibility in primary care practice has been limited. The time required to complete GAS is a barrier to its use by busy primary care clinicians. In this study, we explored the feasibility of lay interviewers completing GAS with older primary care patients. METHODS: Older adults were recruited from participants of a larger study in five primary care clinics in Alberta and Ontario, Canada. GAS guides were developed based on semi-structured telephone interviews completed by a non-clinician lay interviewer; goals were reviewed in a follow-up interview after six months. RESULTS: Goal-setting interviews were conducted with 41 participants. GAS follow-up guides could be developed for 40 patients (mean of two goals/patient); follow-up interviews were completed with 29 patients. Mobility-focused goals were the most common goal areas identified. CONCLUSIONS: Study results suggest that it is feasible for lay interviewers to conduct GAS over the telephone with older primary care patients. This study yielded an inventory of patient goal areas that could be used as a starting point for future goal-setting interviews in primary care. Recommendations are made for use of GAS and for future research in the primary care context.
