Insomnia and poor sleep quality are common problems in patients with cancer. It interferes with the coping ability, symptoms, and treatment outcomes. The Pittsburgh Sleep Quality Index (PSQI) is a reliable, valid instrument to assess the quality of sleep in patients with cancer.
The study was conducted at the department of medical oncology of a tertiary cancer care center. Consecutive eligible participants were recruited and evaluated for sleep quality using PSQI questionnaire. The questionnaire was administered only once with the questions evaluating to the quality of sleep over the last 1 month. A PSQI total score of ≤5 was suggestive of good quality of sleep and a score of >5 was indicative of poor quality of sleep.
Ninety-two consecutive consenting cancer patients admitted for chemotherapy participated in the study. Thirty-one (33.7%) patients had early cancer and 35 (38%) patients had Stage IV metastatic disease. Thirty-six (39.1%) patients reported sleep of <6 h and 30 (32.6%) patients had impaired functioning during day due to sleepiness. Fifty-three (57.6%) patients had poor total PSQI score, of which 39 (73.5%) were female and 14 (26.5%) were male. The study showed no correlation of the PSQI scores with the stage of the disease, and the prior treatment received.
The study showed that Indian cancer patients have short sleep duration and poor quality of sleep. A higher prevalence of sleep disturbances was seen among female cancer patients. PSQI questionnaire can be a cost-effective way of screening cancer patients for poor quality of sleep.
失眠和睡眠质量差是癌症患者的常见问题。它会干扰应对能力、症状及治疗效果。匹兹堡睡眠质量指数（PSQI）是评估癌症患者睡眠质量的可靠有效工具。
本研究在一家三级癌症护理中心的医学肿瘤学部门进行。连续招募符合条件的参与者，使用PSQI问卷评估睡眠质量。该问卷仅发放一次，问题评估的是过去1个月的睡眠质量。PSQI总分≤5表明睡眠质量良好，得分>5则表明睡眠质量差。
92名连续同意参与研究的接受化疗的癌症患者参与了本研究。31名（33.7%）患者患有早期癌症，35名（38%）患者患有IV期转移性疾病。36名（39.1%）患者报告睡眠时间<6小时，30名（32.6%）患者因困倦导致白天功能受损。53名（57.6%）患者的PSQI总分较差，其中39名（73.5%）为女性，14名（26.5%）为男性。研究表明PSQI得分与疾病分期及既往接受的治疗无相关性。
该研究表明印度癌症患者睡眠时间短且睡眠质量差。女性癌症患者中睡眠障碍的患病率更高。PSQI问卷可能是筛查睡眠质量差的癌症患者的一种经济有效的方法。
