BACKGROUND

Pre-consultation tools have been proposed as a solution to support primary care providers in effectively managing the growing number of older adults. Despite older adults making up 25% of primary care consultations, few tools are specifically adapted for them, and most only assess their physical health. The Evaluation SOcio-GERiatrique (ESOGER) tool, a short web-based pre-consultation questionnaire of older adults' physical, mental, cognitive, and social support needs, administered by phone, may provide an effective means of supporting providers in improving patient outcomes in the primary care setting.

OBJECTIVE

To evaluate the effectiveness of the ESOGER tool in improving health-related quality of life and unplanned health service use for older adults in the primary care context.

METHODS

A multi-center, individually-randomized parallel-group controlled trial was conducted at four university affiliated interprofessional primary care clinics in Quebec, Canada. Participants were randomized 1 to 1 to either the intervention or standard care group. The intervention group was administered the ESOGER tool by phone by clinic staff (total of 12 clinic staff across sites) at least one day prior to their consultation with their health provider. The ESOGER tool generated a report for the provider to view at the time of consultation. Although clinics were not blinded to group assignment, patients were blinded unless the tool was mentioned during consultation with the health provider.
The primary outcome of interest was self-reported health-related quality of life (HRQoL) as measured by the EuroQol 5D (EQ-5D). Secondary outcomes were self-reported unplanned visits to their family doctor, visits to the emergency department (ED) and hospitalizations within the last three months. Data were collected at baseline and 3 months.
An intention-to-treat (ITT) analysis was carried out for the study outcomes. The primary outcome was analysed using beta regression. Secondary outcomes were analysed using logistic regression. Inverse probability of censoring weighting was used to impute missing data due to censoring.

RESULTS

Of the 452 eligible to participate, 111 were lost to follow up, for a total sample size of 341 (75.4%) participants. No significant differences in the EQ-5D were observed between the intervention and the standard care group (OR = 1.0, 95%CI [0.5, 2.0]) or the secondary outcomes.

CONCLUSIONS

ESOGER, a pre-consultation tool in the primary care setting for older adults, did not have an effect on health-related quality of life or unplanned health service use when compared to standard care. The non-significant results of the ESOGER tool could be due to a ceiling effect, a limited follow-up duration, or lack of resources for the implementation of the ESOGER tool. Given the potential of pre-consultation tools to support the management of older adults, further research should explore the conditions under which these tools can lead to positive patient outcomes.
