Insomnia in hospitalised patients with advanced disease: prevalence and related factors

Objectiu: Avaluar prevalença i factors associats a l’insomni en pacients ingressats a una unitat de cures pal•liatives. Mètode: Entrevista estructurada a pacients consecutivament ingressats avaluant l’insomni a través de l’escala Sleep Disturbance Scale, i els factors físics, psicològics i ambientals potencialment associats. Resultats principals: El 47% presentà insomni moderat a sever. Els factors potencialment associats més prevalents foren dolor, distrés psicològic, rumiacions nocturnes i factors ambientals. En l’anàlisi multivariada, rumiacions nocturnes i somnolència diürna (relació inversa) es relacionaren amb insomni moderat a sever. Conclusions: L’insomni és un símptoma prevalent relacionat amb rumiacions nocturnes i absència de somnolència diürna.

Aim: To evaluate the prevalence and factors associated with insomnia in patients admitted to a palliative care unit. Method: Consecutively admitted patients were surveyed, evaluating insomnia with the Sleep Disturbance Scale, as well as physical, psychological and environmental potentially associated factors. Main results: 47% of the 61 included patients presented moderate to severe insomnia. Prevalent potentially associated factors were pain, psychological distress, nocturnal rumination and environmental factors. In a multivariate analysis, nocturnal rumination and daytime somnolence (inverse relationship) were associated with moderate to severe insomnia. Conclusions: Insomnia is a prevalent symptom associated with nocturnal rumination and daytime somnolence.
