[Effect of an interdisciplinary group intervention on frail patients: A pre-post quasi-experimental study]

To evaluate the effect of an interdisciplinary group intervention in frail patients in relation to their frailty index, eating habits, quality of life and prescribed pharmacological regimen.

Non-controlled, quasi-experimental longitudinal study. A pre-post intervention.

Sant Hipòlit de Voltregà Primary Health Care Center, Barcelona.

Sixty-one participants were recruited who met the initial frailty diagnosis (0.20-0.35 VIG frailty index). Finally 6 participants dropped out of the intervention and 55 participants completed the study.

Individualized intervention with psychosocial assessment, adequacy of the therapeutic plan assessment and interdisciplinary group intervention of 12 sessions to inform on the management of frailty.

Sociodemographic/psychosocial information was collected from the clinical history, the participant's level of frailty was assessed using the VIG-frail test, quality of life was assessed using the EuroQol questionnaire, adherence to the Mediterranean diet using the PREDIMED questionnaire and the adequacy of the therapeutic plan by measuring the decrease in medication-related incidents.

Statistically significant improvements were observed in the PREDIMED Mediterranean diet adherence test (p-valor=001) and in the aspects of the EuroQol test related to the level of anxiety/depression (p-valor=037). Pharmacological incidences were reduced by 45.28%.

This interdisciplinary preventive intervention helps people with initial frailty to build healthy eating habits, promotes emotional well-being and reduces medication-related incidences.
