Sleep Quality Among Patients With Venous Ulcers: A Cross-sectional Study in a Health Care Setting in São Paulo, Brazil.

 This was an exploratory, descriptive, cross-sectional study to assess sleep quality in 100 patients with venous ulcers using the Pittsburgh Sleep Quality Index (PSQI). Thirty-six (36%) patients had a global PSQI score < 5, indicating that they were good sleepers, while 64 (64%) patients were considered poor sleepers. Fifty-three (53%) patients reported going to bed between 9:00 pm and 11:00 pm, 63 (63%) taking from 16 to 30 minutes to fall asleep, and 41 (41%) waking up after 4 to 5 hours of sleep.
