Obstructive sleep apnea (OSA) is a serious and often underreported condition, despite its highly prevalent distribution. Primary care physicians (PCPs) play an integral role in screening and managing patients with a high risk of developing OSA. This northern Saudi Arabian cross-sectional survey assessed the knowledge and attitude towards OSA among 264 randomly selected PCPs using the OSA Knowledge and Attitude (OSAKA) questionnaire. Among the participating PCPs, 43.9% and 45.1% had low scores in the knowledge and attitude categories, respectively. More than three-fourths (78%) of them recognized that an overnight sleep study is the gold standard for diagnosing OSA. Regarding referral, 39.4% of the OSA patients encountered by the PCPs were referred to ENT specialists, while 21% were referred to sleep clinics, and 18.2% were referred to pulmonologists. Nearly half (50.8%) of the participants recognized OSA as an important clinical disease, and 56.8% were confident in caring for OSA patients. Spearman’s correlation of the current study identified a positive correlation between knowledge scores and attitude scores (rho—0.151, p = 0.017). It is important to improve PCPs’ knowledge regarding OSA and the necessity for referral through different training methods. Furthermore, the study findings emphasize the need to include appropriate OSA programs and continuing medical education for PCPs.

Primary care physicians play a vital role in preventing the progression of diabetic retinopathy (DR) from the initial stages to the late stages. This questionnaire-based analytical cross-sectional study was carried out to assess the knowledge, attitude, practices, and their correlation among 274 randomly selected primary care physicians in Saudi Arabia. Among the studied population, high knowledge, attitudes, and practice scores were observed in 21.5%, 15%, and 29.2% of the physicians, respectively. The mean knowledge score was significantly higher among the age group of less than 30 years (p = 0.031) and the female gender (p = 0.012). The attitude scores were significantly higher among the Saudi physicians (p = 0.027) and those with PHC work experience of less than five years (p < 0.001). Regarding the practices, a significant association was found among the age group of less than 30 years (p = 0.019) and Saudi physicians (p = 0.003). There was a significant positive correlation between knowledge (correlation coefficient (r) = 0.739, p < 0.001) and attitude (r = 0.479, p = 0.007) with the practice scores. It is recommended that targeted continuous medical education, workshops, and seminars are conducted on the prevention and care of DR among primary care physicians. Furthermore, an exploratory multicenter study that involves primary care physicians belonging to all ministries and private sectors is warranted.

Introduction: Diabetes mellitus (DM) microvascular complications can impair corneal sensitivity and lacrimal gland functioning, leading to dry eye disease (DED). Hence, this study aimed to measure the prevalence and severity of DED symptoms, and the related risk factors, among the Saudi diabetic population. Methods: This is a retrospective, cross-sectional, survey-based study which targeted Saudi adults (20 years and older) previously diagnosed with type 1 or type 2 DM. It was conducted in eight primary healthcare centers (PCHs) scattered around eight different provinces of Saudi Arabia (SA). The prevalence and severity of DED were measured by the Ocular Surface Disease Index (OSDI). Results: The total study population was 389 subjects, of which 182 (46.8%) were males and 207 (53.2%) were females. The overall prevalence of DED was 51.7%. Among those, 20.3% of patients had mild dryness, 11.1% had moderate dryness, and 20.3% had severe dryness. Glycosylated hemoglobin (HbA1c) levels of 6.5% or higher proved to be an independent risk factor for the development of DED symptoms, 3.6-folds higher for HbA1c levels of 6.5% to 9% (AOR=3.573; p=0.001), and 2.3-folds higher for HbA1c levels higher than 9% (AOR=2.293; p=0.013). The long duration of diabetes did not show a significant association with manifesting DED symptoms (p=0.263). Conclusion: Half of the diabetic population complained of DED symptoms, compared to one-third of the previously studied general Saudi population. Patients with mild to moderate HbA1c elevation were more likely to report DED symptoms than those with severe elevation, which could be related to impaired corneal sensation. Therefore, a routine ophthalmological examination is recommended.
