To explore and understand KSA’s fundamental healthcare system reform, the potential changes and challenges, and their impacts on major stakeholders. To gain in-depth insights into healthcare leaders’ perspectives regarding healthcare system reform in KSA, a qualitative research approach was used. Ten participants from diverse backgrounds were selected, representing various sectors in KSA: private, public, executive, consulting, and regulatory. This study was conducted between august 2022 and June 2023. The findings revealed four key themes that shed light on healthcare system transformation in KSA and its effects: healthcare system reform, the impact of corporatization/privatization on healthcare providers, the impact of corporatization/privatization on health insurance, and the impact of corporatization/privatization on the workforce. Furthermore, the findings indicated that the ongoing transformation of the public sector toward privatization in KSA faces various challenges that affect most, if not all, stakeholders in the sector. However, the private sector possesses several strengths that can aid in addressing the challenges associated with the rapid transformation of the system. These strengths include familiarity with the market, robust financial management, extensive experience in coding and billing payers and insurance companies, efficient decision-making processes, flexibility, and maturity. The study facilitated comprehensive insights into the transformation of KSA’s healthcare system and the public sector’s shift toward corporatization/privatization. The sector must enhance its capabilities by establishing specialized units and recruiting talent. Further studies are also needed to gain a deeper understanding of the obstacles hindering the transformation.

Frequent visits to diabetes care clinics linked with better control of diabetes mellitus (DM), but debates exist about how frequently visits should be done. The objective of this study was to assess the effect of frequent visits on diabetes care and control. A prospective study of 100 diabetic patients attending Prince Abdul-Aziz Bin-Majed Diabetes Care Centre (PAMDCC), Al Madinah Al Munawwarah, Saudi Arabia, during the period from March 2011 through December 2012. Demographics, lifestyle, and diabetes data were obtained at the index visit. At that and subsequent visits, glycosated hemoglobin (HBA1c), blood pressure (BP) and low-density lipoprotein (LDL) were measured. All these data together with visit number and gap were recorded. Statistical analysis including linear regression analysis was done. A significant reduction in the mean of diabetic control parameters was observed at the last visit. The highest mean changes were observed in patients with > 6 visits, visit gap =8. Adjusted linear regression showed that each visit significantly lowered HBA1c by 0.25%, BP by 2.1/0.7 mm Hg and 0.2 mmol/L for LDL. The number of visits needed to get HBA1c < 7% and BP < 130/85 was 8 and 5 visits with a visit-month index of 14 and 5, respectively. The study suggests that frequent visits at short intervals may lead to better diabetes control. Other prospective clinical trial studies are needed to confirm these findings and to outline the appropriate cost-effective intervals and visit gaps.

Consumption of performance enhancing agents (PEAs) has a wide range of negative health consequences, but knowledge of these consequences among gym users of PEAs in Saudi Arabia is not well understood. Identify the knowledge, awareness, beliefs and attitudes of gym users about negative health consequences of using PEAs, and the relationship between these factors and use of these agents. Cross-sectional study. Five gyms in Madinah city, Saudi Arabia. Convenience sampling was used to recruit gym users. An electronic self-administered questionnaire was used to collect data. Level of knowledge about the negative health consequences of PEAs among gym users. About 70% of 316 participants had used one or more of PEAs over the last six months. Of those, about 68.4% used protein powder supplements and 48.1% used energy drinks. Participants who believed that protein powder supplements (c2=52.3, P < .01) and energy drinks (c2=35.2, P < .01) had health hazards used these agents less often than others during the six months preceding data collection. Participants who had less knowledge about the negative health consequences were more likely to use protein powder supplement (t=2.38, P=.018). On the other hand, those who were more knowledgeable about the negative health consequences of insulin, were more likely to use insulin (t=2.45, P=.015). Misuse of PEAs is widespread among gym users in Saudi Arabia. Improving the level of knowledge and awareness of possible serious health consequences would hopefully lead to reduced PEA consumption. The temporal sequence of cause and effect could not be determined in a cross sectional study. Convenience sampling in a single city limited the generalizability of the findings to all regions of Saudi Arabia.

OBJECTIVES: To assess the nutrition and health status, nutrients intake, and physical activity among Saudi medical students. METHODS: A cross-sectional survey using a questionnaire, anthropometric measurements, and laboratory assessments was conducted from January to May 2011 on 194 randomly selected Saudi medical students at Taibah University, Madinah, Kingdom of Saudi Arabia. The adequacy of nutrient intake was compared with the recommended daily intake (RDI) per the National Research Council. RESULTS: Caloric intake was derived from carbohydrates (72.1%), fats (19.4%) and proteins (8.4%). Proteins and fats were obtained from a greater number of animal sources than of plant sources (5.3% versus 3.2% for proteins and 11.6% versus 7.8% for fats). There were low percentages of RDI of fibers (8.5%), most vitamins especially vitamin D (14.2%), and minerals (potassium (31.3%), zinc (40.7%), magnesium (24.5%), and calcium (47%). Overall, 34.5% of the students were overweight, and 10.3% were obese. Dyslipidemia was diagnosed in 24.7%, and 56.2% had high high-sensitivity C-reactive protein (hs-CRP). There was a positive correlation between the median caloric intake and both the BMI (r=0.42, p =0.00) and hs-CRP (r=0.3, p =0.001). Inactivity was prevalent among the students (64.4%). CONCLUSION: This study showed deficiencies in several essential nutrients among medical students, and the prevalence of overweight status, obesity, and inactivity were relatively high. These results indicate the need to improve nutrition and promote healthy lifestyles among the medical students.

Background: Diabetic foot is a serious and often debilitating diabetes complication that poses a significant risk of morbidity and even mortality. However, ensuring good knowledge and good practice of appropriate foot care for patients with diabetes has been frequently neglected in diabetes management. Objectives: This study aimed to assess foot care knowledge and practice in patients with diabetes. Methods: We conducted a cross-sectional study on 400 patients with diabetes at Madinah Diabetes Center, Madinah City, Saudi Arabia, in 2023. Sociodemographic, knowledge score, practice of foot care, and diabetes-related data were collected using a valid interview structured questionnaire. The prevalence of good knowledge and practice level was calculated and compared using the studied patients’ characteristics using appropriate statistical tests. Results: The prevalence of good knowledge of foot care and its practice was 35% and 27%, respectively. The knowledge level showed statistically significant differences among patients based on their age and diabetes type and duration. Patients who were >50 years (70.1%), had type 2 diabetes (89.5%), and with diabetes duration >10 years (65%) showed significantly better knowledge. Female patients (65.7%) had a higher good practice level compared with male patients (34.3%) (p < 0.001). Conclusions: This study highlights the insufficient knowledge and inadequate foot care practice among patients with diabetes in the studied population. Educational interventions and targeted strategies are necessary to improve knowledge about the importance of foot care and promote better foot care practices among patients with diabetes.
