Factors associated with sleep quality in the elderly receiving chemotherapy.

OBJECTIVE

to evaluate the characteristics of sleep and the factors associated with the quality of sleep in elderly patients receiving outpatient chemotherapy treatment.

METHOD

cross-sectional study with 140 elderly patients (51.2% female, average age 69.8 years) with stage III or stage IV cancer (67.9%), undertaken in a university hospital in the state of São Paulo in 2010. The following instruments were used: sociodemographic and clinical characterization questionnaire, validated by specialists; Pittsburgh Sleep Quality Index; Piper Fatigue Scale-reviewed; and a scale for the subjective measurement of pain.

RESULTS

the majority of the elderly (62.9%) had a score compatible with poor sleep quality. On average, the duration of sleep was 388.0 minutes, latency was 44.6 minutes and efficiency of 83.8%. Through multiple logistic regression analysis, an increase of 21% in the probability of having poor sleep quality was observed for each single-point increase in the intensity of the pain.

CONCLUSION

nursing interventions aiming to promote better sleep quality for elderly patients with cancer must include measures for pain control.
