Electronic frailty index validated for predicting health complications in the elderly

A new research paper was published in Aging (indexed by MEDLINE/PubMed as “Aging (Albany NY)” and “Aging-US” by Web of Science), on October 24, 2024, Volume 16, Issue 20, entitled, “Development and validation of an electronic frailty index to a national health maintenance organization’.

The study, led by researchers Fabienne Hershkowitz Sikron, Rony Schenker, Yishay Koom, Galit Segal, Orit Shahar, Idit Wolf, Bawkat Mazengya, Maor Lewis, Irit Laxer and Dov Albukrek from the Meuhedet Health Maintenance Organization (HMO) in collaboration with colleagues The Joint-Eshel Organization and Israel’s Ministry of Health are introducing the Meuhedet Electronic Frailty Index (MEFI) – a digital tool designed to assess frailty in the elderly and identify those most at risk for serious health outcomes such as hospitalization or death.

As people live longer, identifying those at higher risk for health complications is essential to maintaining quality of life in older age. Frailty, a condition characterized by increased vulnerability to adverse health outcomes, has emerged as a critical predictor of health decline in the elderly. While vulnerability assessment tools exist, this study adapts and validates an Electronic Vulnerability Index (EFI) tailored specifically to Israeli data and healthcare infrastructure, allowing for more targeted and culturally relevant assessments.

The MEFI was developed using data from 120,986 people aged 65 and over, covering different indicators including physical, social and cognitive deficits. The index classifies individuals as “fit,” “mildly frail,” “moderately frail,” or “severely frail” and is incorporated into Israel’s electronic health record system.

The researchers found that patients with higher MEFI scores faced significantly increased risks of hospitalization or mortality within one year, with risk levels quadrupling for the frailest compared to those classified as able-bodied. According to the authors, “the findings also showed that the MEFI version we created is valid for predicting mortality or hospitalization and had better predictive accuracy compared to the CCI,” underscoring its reliability in health risk assessment. This integration allows Meuhedet HMO to implement proactive and preventative care measures across its network.

In addition to predicting hospitalization and mortality, MEFI’s alignment with Israel’s National Social Security benefit system enhances its validity and practical use. As the authors note, “As a health care organization, our mandate is to help our patients live longer and better lives. Using MEFI as part of routine primary care can help us achieve this goal.” By focusing on early intervention for those most at risk, MEFI could significantly impact health care costs and allow clinicians to allocate resources more efficiently.

This new EFI version places Israel at the forefront of frailty research, and its success could pave the way for other countries with similar healthcare systems to adopt or adapt the approach. Future steps include integrating MEFI as a routine part of primary care in Israel to ensure early intervention and support as patients age.

In summary, MEFI is a powerful tool that empowers Israel’s health care system to identify and support older adults who are most in need, marking a major advance in caring for an aging population.
