Abstract
Objective

The aim of this study was to evaluate the potential association between medication-related safety incidents in home care settings reported by informal caregivers and their emotional burden levels.

Methods

A cross-sectional study was conducted among informal caregivers of senior patients aged over 65 years requiring daily care. Participants completed the 7-item Zarit Caregiver Burden Scale and self-reported medication safety incidents.

Results

In total, 176 participants responded. Medication safety incidents were reported by 25.6% of them. Caregiver burden was independently associated with a higher likelihood of self-reported medication safety incidents, with an odds ratio of 2.16 (95% CI: 1.03–4.50), after adjusting for caregiving hours. In addition, male sex was also independently associated with increased risk, with an odds ratio of 2.29 (95% CI: 1.06–4.98).

Conclusions

This study shows that caregiver burden is associated with self-reported medication-related incidents in home care. Targeted interventions that promote informal caregiver well-being may reduce safety incidents and enhance the sustainability of informal care. This study suggests that training programs should address medication safety using gender-sensitive strategies and incorporate tools to alleviate caregiver burden.

Trial registration NCT05885334 (date 2023-06-01).

Resumen
Objetivo

El objetivo de este estudio fue evaluar la posible asociación entre los incidentes de seguridad relacionados con la medicación en el ámbito de los cuidados domiciliarios, reportados por cuidadores informales, y sus niveles de sobrecarga emocional.

Métodos

Se llevó a cabo un estudio transversal entre cuidadores informales de pacientes mayores de 65 años que requerían cuidados diarios. Los participantes completaron la Escala de Sobrecarga del Cuidador de Zarit en su versión de 7 ítems y notificaron incidentes de seguridad relacionados con la medicación.

Resultados

En total participaron 176 personas. El 25,6% reportó incidentes de seguridad con la medicación. La sobrecarga del cuidador se asoció de forma independiente con una mayor probabilidad de incidentes reportados de seguridad de la medicación, con una razón de momios de 2,16 (IC 95%: 1,03-4,50), tras ajustar por horas de cuidado. Además, el sexo masculino también se asoció de forma independiente con un mayor riesgo, con una razón de momios de 2,29 (IC 95%: 1,06-4,98).

Conclusiones

Este estudio pone de relieve la sobrecarga del cuidador como un factor clave que contribuye al aumento de los riesgos de seguridad de la medicación en el cuidado domiciliario. Las intervenciones dirigidas a promover el bienestar de los cuidadores informales pueden reducir los incidentes de seguridad y mejorar la sostenibilidad del cuidado informal. Este estudio sugiere que los programas de formación deberían abordar la seguridad de la medicación mediante estrategias sensibles al género e incorporar herramientas para aliviar la sobrecarga del cuidador.
