Background Healthcare workers' (HCWs) compliance with infection prevention and control (IPC) measures during the COVID-19 pandemic is crucial to reducing the spread of infection to their colleagues, families, and community. This study assessed the risk perception and compliance with personal protective equipment (PPE) usage, hand hygiene, and specific IPC measures and explored the factors associated with compliance among nurses during the third wave of the COVID-19 pandemic in Egypt. Methods A hospital-based cross-sectional survey was conducted at the Alexandria Main University Hospital (AMUH) in Alexandria city from May to August 2021, where 354 nurses were included with a response rate of 94.9%. A structured interviewer-administered questionnaire was used for data collection. Univariate and multivariate logistic regression analyses were conducted. Results The overall compliance with PPE usage, hand hygiene, and IPC measures was 81.9%. The mean risk perception score was 40.9 ± 3.3. More than 95% of nurses were aware of the high risk of COVID-19 infection at their workplace, the serious consequences of the disease, and the risk that can be minimized by using PPE, whereas a relatively low percentage of nurses believed that the risk of COVID-19 infection could be reduced by using a surgical mask (19.2%) or gloves (50.5%). Good compliance was independently predicted by risk perception (OR = 1.25; 95% CI = 1.13, 1.39), and knowledge about PPE usage and hand hygiene (OR = 3.53; 95%CI = 2.40, 5.19). Facilitators of compliance with the PPE usage were attending suspected or confirmed COVID-19 cases in their hospital ($$\overline{x}$$ x ¯ = 9.82), comfort to use the PPE ($$\overline{x}$$ x ¯ = 9.16), availability of PPE ($$\overline{x}$$ x ¯ = 8.96), hospital policy ($$\overline{x}$$ x ¯ = 8.74), and senior compliance ($$\overline{x}$$ x ¯ = 6.5). Conclusions Nurses at AMUH reported high risk perceptions. The rate of compliance with PPE usage, hand hygiene, and IPC measures was 81.9%. The personal risk perception and knowledge about the PPE usage and hand hygiene are the keys to improving compliance in a healthcare facility.

e17576 Background: With the increase in survival of cancer patients, consequently, increasing their quality of life is mandatory as well. Sleep disturbances, particularly Obstructive Sleep Apnea (OSA), is one of the main complaints of cancer patients in which patients face frequent episodes of upper airway closure during sleep. Possible causes for OSA include either the specific cancer or its treatment whether sedatives, narcotics, radiotherapy, or chemotherapy, but the primary cause is still hard to prove. Our aim was to investigate the association between the occurrence of OSA and radiotherapy in cancer patients. Methods: On the 9th of September, 2018, we have searched comprehensively 12 electronic databases to retrieve relevant studies. All eligible studies that assess the association between OSA and radiotherapy in cancer patients were included in our meta-analysis. Quality assessment of included studies was done using the NIH tool for cohort and cross-sectional studies. Results: Fourteen studies met our selection criteria, eight studies were eligible for our meta-analysis. There was a positive association between the occurrence of OSA and radiotherapy in cancer patients (OR 1.16, 95% CI [0.52–2.56]; P = 0.718). OSA was noted in 103 of 181 cancer patients who received radiotherapy, yielding a remarkable overall prevalence of 63% (95% CI [0.36–0.85]; P = 0.343). A positive risk ratio for the development of OSA in cancer patients treated with radiotherapy was detected (RRs 1.27, 95% CI [0.81–2.00]; P = 0.297). The overall mean of apnea hypopnea index (AHI) for patients with OSA in six studies was 22.45. Conclusions: These findings point to a striking association between OSA risk and radiotherapy in cancer patients. Since the early recognition and management of OSA in such patients may play an important role in improving their quality of life, we recommend screening all cancer patients treated with radiation for early signs of OSA to further improve their survival.
