Extending geriatric care beyond traditional settings: lessons from a mobile assessment program

As populations age, changing living conditions and declining self-advocacy often create barriers to essential care. Mobile Geriatric Teams (MGTs) offer a potential solution by providing assessments within a patient's regular environment, potentially reaching underdiagnosed and undertreated individuals who struggle to access routine healthcare. The aim of this study was to evaluate the clinical impact and reach of MGTs in the Northern District of Israel. Specifically, we aimed to assess the extent of MGT-initiated Comprehensive Geriatric Assessments and compare therapeutic and diagnostic outcomes between patients seen by MGTs and those receiving standard community-based geriatric consultations.

This is a retrospective, data-based study serving as a proof-of-concept evaluation for MGT implementation in Israel. The intervention was implemented in MHS between January 1, 2020, and December 31, 2023, and data were collected 3 and 6 months after the MGT appointment. Group comparisons were conducted using chi-square tests, Fisher's exact tests, and Wilcoxon rank-sum tests. In addition, we performed matched logistic regression models.

A total of 8,152 individuals were included in the study; 4,348 were assessed by MGTs. The MGT group participants were slightly older and had a higher proportion of males and a lower SES category than the comparison group. The MGTs group had fewer diagnoses of mild cognitive impairment, dementia, and depression, compared to the comparison group. They also had more diagnoses of orthostatic hypotension, and they were more likely to be assessed for fall risk. The MGT group was also prescribed fewer medications in the months following the assessment. After the MGT intervention, we report an increase in primary care visits in the relevant population in the district where it was implemented, while the comparison group did not have a corresponding trend.

In this study, we demonstrated that MGTs can reach a specific subpopulation of the elderly who might not otherwise undergo a geriatric assessment, primarily males, those of low SES, and possibly those with less urgent health concerns. These findings highlight the complementary role of MGTs in increasing accessibility, promoting equity, and addressing unmet needs in populations less likely to seek care on their own.
