[Quality of life in institutionalized older adults with moderate to severe major neurocognitive disorder: Effect of Doll therapy]

Background and objectives: Major neurocognitive disorder is characterized by progressive cognitive impairment, a decrease in the person's ability to perform activities of daily living and the appearance of psychological and behavioral symptoms that lead to a deterioration in the quality of life and progression towards institutionalization. The most common management of major neurocognitive disorder is pharmacological therapy that mitigates or slow progressive deterioration and symptom control. The objective of this study was to establish the effect of a nursing intervention based on Doll therapy, compared to conventional care on the quality of life of older adults with moderate to severe major neurocognitive disorder institutionalized in nursing homes in the city of Medellín, Colombia.

Methods: Pilot experimental study with two groups and pretest post-test measurement. The sample consisted of 26 institutionalized elderly adults with advanced-stage major neurocognitive disorder, randomly assigned to each group. The experimental group received Doll therapy, based nursing therapy, while the comparison group continued to receive conventional therapy according to the institution's protocol. The QUALID instrument was used, which was evaluated by professionals external to the care centers.

Results: The comparison of the groups, before and after the intervention, indicates that the experimental group showed a positive effect on quality of life, supported by the statistical significance of the data, with a moderate effect.

Conclusions: The Doll therapy as a non-pharmacological therapy has a positive effect on the quality of life of patients with moderate to severe major neurocognitive disorder, which constitutes a contribution to strengthen the knowledge associated with the effects or this intervention.
