Background: Sickle cell disease (SCD) is among the prevalent chronic diseases in the Eastern Province of Saudi Arabia. To our knowledge, there is no published research that reports the reasons for hospitalization in the Eastern Province of the country. Therefore, this study aimed to fill this gap.Design and methods: This is a retrospective cohort study that was conducted in the period from January 2018 to December 2019. Patients with sickle cell disease who were admitted and treated in the hospital were included in this study. Patients' sociodemographic data and reasons for hospitalization were collected and analyzed using the statistical package for social sciences, version 21 (SPSS, Chicago, IL, USA).Results: There were 103 SCD patients, and the age range was from 18 to 62 years old. The majority of the patients were males (56.3%) and were in the younger age group (≤30 years old; 60.2%). The results showed that the most frequent cause of admission was a vaso-occlusive crisis (VOC) (n=94, 91.3%), followed by acute chest syndrome (ACS) (n=32, 31.1%), and then by hemolytic crisis (27 of the cases; 26.2%). However, we found that a higher number of hip avascular necrosis (AVN) cases were statistically significant in relation to the higher number of hospital admissions (p<0.05), whereas other reasons were not found to have a statistically significant association. Conclusion:The most frequent cause of admission was VOC episodes, followed by ACS, and then by hemolytic crises. Also, a higher number of hip AVN episodes were statistically significant with the higher number of hospital admissions.

Objective This study investigates the relationship between low back pain (LBP) and sleep quality among health care workers in KSA. Methods In this cross-sectional study, an anonymous questionnaire consisting of three sections was administered to health care providers in KSA. The first part included the biographic data of participants, while the second comprised the Oswestry Disability Index (ODI) and the extended version of the Nordic Musculoskeletal Questionnaire (NMQ-E) for LBP. The third part contained the Pittsburgh Sleep Quality Index (PSQI). Results A total of 442 healthcare providers completed the questionnaire. Nearly two-thirds of the respondents were male (62.7%). Most were living in either the central region (23.3%) or the northern region (23.3%). There was a statistically significant correlation between the global PSQI and ODI score (r = 0.235; p < 0.001). The correlation between ODI score and PSQI components including subjective sleep quality (r = 0.229; p = 0.007), habitual sleep efficiency (r = 0.229; p < 0.01), and the daytime dysfunction was also statistically significant. Conclusion Health care providers in KSA with high rating for LBP disability demonstrated poorer overall sleep quality and vice versa. However, further research is essential to investigate whether this relationship is causal.
