Background: Sleep problems and poor sleep quality are important issues for medical students. This study aimed to investigate the sleep patterns, measure the prevalence of poor sleep quality, and identify the predictors of poor sleep among medical students in King Khalid University (KKU), Saudi Arabia.Methods: This cross-sectional study enrolled 318 medical students during OctoberNovember, 2015. Participants were selected by convenience sampling and data were collected using self-administered questionnaires to obtain information regarding socio-demographic variables and indicators of sleep quality.Results: The overall mean sleep quality score was 6.79 with a standard deviation of 3.06. Poor sleep quality was reported by 74.2% students. Significantly high mean sleep quality scores (Pittsburgh Sleep Quality Index) were observed for students with very poor subjective sleep quality (mean = 10.50, SD = 2.58), least sleep efficiency (mean = 11.21, SD = 2.23), shorter sleep duration (mean = 7.83, SD = 2.88), sleep onset latency more than 30 minutes (mean = 7.82, SD = 2.53), sleeping after midnight (mean = 7.53, SD = 2.95), and use of sleep aiding medication (mean = 8.78, SD = 3.5). Significant differences were observed between good sleepers and poor sleepers regarding these sleep characteristics. Poor sleep was predicted by sleep behaviours such as going to sleep after midnight (AOR = 2.18, 95% CI: 1.20, 3.94) and sleep duration of less than seven hours (AOR = 7.49, 95% CI: 4.24, 13.22).Conclusion: Medical students of KKU have poor sleep quality. Longer sleep latency, going to sleep after midnight, and shorter sleep duration are important problems in this group.

Purpose:The aim of this is to find out the hand hygiene (HH) knowledge among primary health care workers (PHCWs) in Abha health district, southwestern Saudi Arabia.Methods:Data were collected through an anonymous self-administered questionnaire. The questionnaire was based on a WHO “Knowledge Questionnaire for Health Care Workers.”Results:The study included 478 PHCWs (239 males and 239 females). The sample included 186 physicians, 212 nurses, and 80 technicians. The highest proportion receiving formal training was nurses (82.1%). Females (77.4%) received significantly more training than males (70.3%). Only 59.2% (283) of the HCWs properly identified unclean hands of HCWs as the main route of the cross. Only 26.4% (126) of the HCWs properly identified germs already present on or within the patient as the most frequent source of pathogens in a health-care facility. Only 54.8% (262) of HCWs properly identified 20 s as the minimal time needed for alcohol-based hand rub to kill most germs on hands.Conclusion:The study revealed gaps in the knowledge regarding HH. To promote HH at primary health care setting, WHO bundle of multimodal strategies should be adopted including system change; training/education; evaluation and feedback; reminders in the workplace; and institutional safety climate.
