The Quality of Blood Donation Services and Its Association with Blood Donors' Trust and Loyalty at Makkah Blood Donation Centers in Saudi Arabia: A Cross-Sectional Study.

The current cross-sectional study was conducted to determine the quality of blood donation services and its association with blood donors' trust and loyalty at Makkah blood donation centers in Saudi Arabia. A total of 373 healthy blood donors aged ≥18 years who visited blood donation centers in Makkah, Saudi Arabia, between 1st and 28th February 2023 were recruited using a census sampling method. A pre-tested and validated Arabic language questionnaire was employed. The study survey included a checklist of sociodemographic variables (seven items), as well as seven-point Likert-scale questions on the quality of blood donation services (21 items), questions to assess the participant's level of trust in blood donation centers (4 items), and questions to evaluate the level of loyalty to blood donations (4 items). SPSS (version 24) was used for data analysis. A total of 373 blood donors were included in this study. Of them, 240 (64.3%) were males and 133 (35.7%) were females. The vast majority of the study participants, 330 (88.5%), had a high educational level. The overall average agreement score for the quality of blood donation services was 71.7%. Furthermore, the overall average item agreement score for trust in blood donation centers and places was 83.0%, while the overall average item agreement score for loyalty to blood donation was 72.1%. Moreover, after adjustment for potential confounding factors, high levels of quality in blood donation services were associated with high levels of trust and loyalty among the blood donors (OR: 1.518, CI 95%: 0.321-0.864 and OR: 2.466, CI 95%: 0.285-0.763, respectively) (p-value < 0.05 for all). The overall quality of, trust in, and loyalty to blood donation services were 71.7%, 83.0%, and 72.1%, respectively. In addition, high levels of quality in blood donation services could improve blood donors' trust and loyalty levels at Makkah blood donation centers in Saudi Arabia.

The epidemiology and incidence of dengue in Makkah, Saudi Arabia, during 2017-2019.

OBJECTIVES: To study the epidemiology of dengue incidence and understand the dynamics of dengue transmission in Makkah, Kingdom of Saudi Arabia (KSA), between 2017-2019. METHODS: This is a cross-sectional study. Health and demographic data was obtained for all confirmed dengue cases in Makkah, KSA, in the years 2017-2019 from the Vector-Borne and Zoonotic Diseases Administration (VBZDA) in Makkah and the Makkah Regional Laboratory, KSA. In addition, entomological data about Aedes density was obtained from the VBZDA. Descriptive epidemiological methods were used to determine the occurrence and distribution of dengue cases. RESULTS: Laboratory-confirmed dengue cases were higher in 2019 as compared to 2017 and 2018, suggesting an outbreak of dengue in Makkah, KSA, in 2019. The incidence of confirmed dengue cases was 204 in 2017, 163 in 2018 and 748 in 2019. Dengue mostly affected people in the 25-44 age group, accounting for approximately half of the annual dengue cases each year. Men were at a higher dengue incidence risk when compared to women, and Saudi women had a higher risk rate for dengue cases when compared to non-Saudi women in all 3 years studied. There was no dengue related death in these 3 years. CONCLUSION: The dengue incidence increased in Makkah, KSA, in 2019 as compared to the previous 2 years, owing to heavy rainfall in 2019. Post-rainfall Vector control efforts may help contain the disease in Makkah, KSA.

Assessment of microbiological quality of food preparation process in some restaurants of Makkah city.

Microbiological contamination of food processing surfaces and utensils increases considerably the risk of food-borne illnesses via cross-contamination. Hence, the safety of served meals and beverages can be evaluated through the assessment of the microbiological quality of food contact surfaces in food-serving establishments. This study carried out in Makkah city aimed to assess the microbiological contamination levels on food processing surfaces and utensils in 43 restaurants from the 9 main districts in the city. A total of 294 swab preparations were taken from 16 types of food contact surfaces including cutting boards, food containers, knives, serving dishes and other utensils were examined. Ninety samples (31%) showed more than 10 CFU/cm2 which were considered positive for microbiological contamination. Meat chopping devices and cutting boards were found as the most contaminated food contact surfaces (60% and 50%), while washed serving dishes and fridge handles were the least contaminated (21% and 18%). Microorganisms detected in the study were Klebsiella spp. (18.7%), Escherichia coli (17,7%), Staphylococcus aureus (4,4%), Pseudomonas spp. (1.7%), Proteus spp. (0.7%), Bacillus cereus (0.7%), and Candida sp. (0.3%). Klebsiella spp. and E. coli were observed in at least one sample from each of the sixteen different food contact surfaces. The incidence of restaurants with contaminated food contact surfaces was significantly variable among the different districts, with a value as high as 57% in the most affected district and 20% in the less affected. No contamination with Salmonella spp. or Listeria spp. was detected, however, the detection of Bacillus cereus, a toxin-forming microorganism, in two different restaurants underlines the need for continuous microbiological assessment to ensure standard sanitation levels in restaurants and catering establishments of Makkah city.
