Conceptual models are abstract representations of the real world. They are used to refine medical and nonmedical health care scopes of service. During the COVID-19 pandemic, numerous analytic ...predictive models were generated aiming to evaluate the impact of implemented policies on mitigating the spread of the virus. The models also aimed to examine the psychosocial factors that might govern the general population's adherence to these policies and to identify factors that could affect COVID-19 vaccine uptake and allocation. The outcomes of these analytic models helped set priorities when vaccines were available and predicted readiness to resume non-COVID-19 health care services.
The objective of our research was to implement a descriptive-analytical conceptual model that analyzes the data of all COVID-19-positive cases admitted to our hospital from March 1 to May 31, 2020, the initial wave of the pandemic, the time interval during which local policies and clinical guidelines were constantly updated to mitigate the local effects of COVID-19, minimize mortality, reduce intensive care unit (ICU) admission, and ensure the safety of health care providers. The primary outcome of interest was to identify factors that might affect mortality and ICU admission rates and the impact of the implemented policy on COVID-19 positivity among health care providers. The secondary outcome of interest was to evaluate the sensitivity of the COVID-19 visual score, implemented by the Saudi Arabia Ministry of Health for COVID-19 risk assessment, and CURB-65 (confusion, urea, respiratory rate, blood pressure, and age >65 years) scores in predicting ICU admission or mortality among the study population.
This was a cross-sectional study. The relevant attributes were constructed based on research findings from the first wave of the pandemic and were electronically retrieved from the hospital database. Analysis of the conceptual model was based on the International Society for Pharmacoeconomics and Outcomes Research guidelines and the Society for Medical Decision-Making.
A total of 275 individuals tested positive for COVID-19 within the study design interval. The conceptualization model revealed a low-risk population based on the following attributes: a mean age of 42 (SD 19.2) years; 19% (51/275) of the study population being older adults ≥60 years of age; 80% (220/275) having a CURB-65 score <4; 53% (147/275) having no comorbidities; 5% (13/275) having extreme obesity; and 20% (55/275) having a significant hematological abnormality. The overall rate of ICU admission for the study population was 5% (13/275), and the overall mortality rate was 1.5% (4/275). The multivariate correlation analysis revealed that a high-selectivity approach was adopted, resulting in patients with complex medical problems not being sent to MOH isolation facilities. Furthermore, 5% of health care providers tested positive for COVID-19, none of whom were health care providers allocated to the COVID-19 screening areas, indicating the effectiveness of the policy implemented to ensure the safety of health care providers.
Based on the conceptual model outcome, the selectivity applied in retaining high-risk populations within the hospital might have contributed to the observed low mortality rate, without increasing the risk to attending health care providers.
We describe the first two cases of invasive disease caused by Haemophilus influenzae serotype A in Saudi Arabia. This is the first known reported invasive Haemophilus influenzae serotype A from Saudi ...Arabia.
A ten-month-old and three-month-old male not known to have any past history of any medical illness and who had received H. influenzae type b (Hib) vaccine presented to our hospital mainly with fever of few days' duration. A provisional diagnosis of meningitis with sepsis was made and laboratory tests were requested. The chest radiograph was normal. The laboratory results revealed leukocytosis, but leukopenia was noticed in the younger infant. Blood culture and cerebrospinal fluid specimens yielded a pure culture of Haemophilus influenzae and serotyping showed the isolates to be serogroup A. Both patients were started on vancomycin and third-generation cephalosporin. On receiving the blood culture result, vancomycin was stopped. Fever subsided after 48 hours, while in the second case, it continued for 12 days from the admission date. The repeat blood cultures were negative. Antibiotic therapy was given for 10 days for the first case with an unremarkable hospital course, while the second case was complicated by seizure and received a longer duration of antibiotics. Both infants were discharged home in good condition.
Invasive non-typeable H. influenzae strains are emerging and there is a need for surveillance of this disease. This has implications in future vaccine development.
The hand hygiene practice (HHP) is the most effective and simplest preventive measure to reduce the risk of infection. HHP is more relevant among pediatric physicians in the context of the COVID-19 ...pandemic since, children are more vulnerable to infection. Therefore, assessment of the COVID-19 impact on HHP could be useful in minimizing lethal virus transmission from pediatric physicians to patients and vice versa.
The present cross-sectional, electronically self-administered supplement based survey study was conducted among different professional levels of pediatric physicians involving consultants, specialists, and residents. The supplement includes information related to demography, knowledge, awareness, preventive measures, demonstration and practice of HHP. The information was collected and summarized on a Microsoft excel sheet before being imported to SPSS for statistical analysis.
Of the total (N = 404) pediatric physicians, 56.68% male, 43.06% belongs to 25–35 years, 42.32% were consultants, 98.01% respondents were familiar with five moments of HHP. Further, HHP immediately before touching patients (99.26%), clean/aseptic procedure (95.04%), after body fluid exposure (72.28%), after touching patients (98.01%), after touching surrounding of patients (74.75%) may prevent germ transmission to patients whereas HHP after touching patients (98.27%), before clean/aseptic procedure (67.57%), after exposure to immediate surroundings of patients (97.02%) may prevent germ transmission to pediatric physicians. Rubbing hands is preferred before palpation of abdomen (74.25%), before giving injection (56.68%), after removing gloves (61.88%), after making a patient's bed (47.80%), while washing of hands preferred after emptying bedpan (67.82%) and after visible exposure to blood (84.40%), 92.57% believed gloves can't replace HHP, posters display at point of care as reminders (95.30%), received frequent HHP education (82.92%), 50.49% do not need HHP reminder, 51.73% preferred alcohol based sanitizer, 53.46% facilitate daily morning huddle, HHP >10 times per day before COVID-19 (24.62%) while in COIVID-19 (56.44%). HPP is the most effective way to prevent the spread (98.01%) of microbes because it kills germs (90.35%), health care associated infections is the major (38.06%) cause of germ transmission, 86.88% will be remains committed to HHP even after pandemic. In comparison to residents and specialists, consultants gave more importance (p = 0.02) to HHP and were more adherent during (p = 0.007) and even after (p = 0.001) COVID-19 pandemic.
Assessing knowledge of pediatric physician, awareness, and adherence to hand hygiene measures could be helpful to reduce the contact transmission of lethal viruses to patients and vice versa. Further increase in the awareness, knowledge and education of HHP are required in order to maximize its utilization.
