The objective of this present study was to assess whether an intervention based on nurse home visits including alert buttons (NV+AB) is effective in reducing frailty compared to nurse home visits alone (NV-only) and usual care (control group) for older adults.

Patients were aged over 60 years with a frailty index score higher than 0.14. After screening and informed consent, participants were allocated randomly to the control, NV+AB, or NV-only groups. The framing sample included 819 patients. Of those, 591 were not located because they did not have a landline/telephone (341 patients), they had died (107), they were ill (50), or they were not currently living in the city (28).

A screening interview was applied to 228 participants, and 57 had a score ≤0.14, 171 had ≥0.14, and 16 refused to complete the baseline questionnaire. A home visit was scheduled for 155 patients. However, 22 did not complete the baseline questionnaire. The final 133 subjects were randomized into the NV+AB (n = 45), NV-only (n = 44), and control (n = 44) groups.

There were no statistically significant differences in the baseline characteristics of the groups. The mean age overall was 76.3 years and 45% were men. At the baseline, 61.65% were classified as frail. At the end of the follow-up period the adjusted prevalence of frailty in the NV+AB group was 23.3% versus 58.3% in the control group.

The authors conclude that an intervention based on NV+AB seems to have a positive effect on frailty scores.
