Revisiting the Prevalence of Autism Spectrum Disorder among Omani Children: A multicentre study

Objectives: This study aimed to provide an updated estimate of the prevalence of autism spectrum disorder (ASD) among Omani children. Methods: This retrospective descriptive study was conducted from December 2011 to December 2018. Data were retrieved from the three main autism diagnostic centres in Oman: Sultan Qaboos University Hospital, Royal Hospital and Al-Massarah Hospital. The ASD diagnosis was made by experienced clinicians based on the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). The overall population prevalence estimates per 10,000 children aged 0–14 years old in Oman were calculated using the denominator of the mid-period population data. Results: A total of 1,705 ASD cases were identified with the majority of cases being male (78.1%). The overall prevalence rate of ASD was estimated at 20.35 per 10,000 children (95% confidence interval: 19.39–21.32) between 2012–2018. Boys were found to have a 3.4-fold higher prevalence of ASD than girls (31.23/10,000 versus 9.07/10,000). Regionally, the majority of cases were found in the capital, Muscat, where the highest prevalence was 36.51 cases per 10,000 children. Conclusion: The prevalence of ASD among Omani children is 15-fold higher than estimates from 2011. This increase can be attributed to improvements in diagnostic services, increased awareness of ASD, better screening programmes and changes in diagnostic criteria. In addition, this increase in prevalence suggests a need for a registry of developmental disabilities and more extensive diagnostic and rehabilitation services in Oman.Keywords: Autism Spectrum Disorder; Epidemiology; Prevalence; Oman

Evidence-Based Practice : Knowledge, attitudes, practice and perceived barriers among nurses in Oman

Objectives: The aim of this study was to describe nurses’ practices, attitudes, knowledge/skills and perceived barriers in relation to evidence-based practice (EBP) in Oman. Methods: This descriptive cross-sectional study was conducted between February and November 2012. A self-reported 24-item questionnaire was used to measure EBP practices, attitudes and knowledge/skills among a convenience sample of 600 nurses working in four governmental hospitals in Muscat, Oman. Responses were scored on a one to seven rating scale. Barriers to EBP were measured on a five-point Likert scale using two subscales. Descriptive statistics and general linear regression were used to analyse the data. Results: A total of 414 nurses were included in the study. The greatest barriers to developing EBP among nurses were insufficient time for research (3.51 ± 0.97) and insufficient resources to change practices (3.64 ± 0.99). Nurses with more years of experience reported increased use of EBP (P <0.01), more positive attitudes towards EBP (P<0.001) and fewer barriers to research (P <0.01). Significant positive correlations were found between years of experience and practice (r = 0.16) and attitudes (r = 0.20). Nurses with a baccalaureate degree reported fewer barriers to research than those qualified at a diploma level (P <0.001). Nurses who perceived more barriers to research reported less use of EBP (P <0.001), less positive attitudes towards EBP (P <0.001) and limited EBP knowledge/skills (P <0.001). Conclusion: These findings provide a basis for enhancing nursing practices, knowledge and skills. Continuing education for nurses and minimising barriers is crucial to increasing the use of EBP in Oman.Keywords:

Pattern of Viral Infections among Infants and Children Admitted to the Paediatric Intensive Care Unit at Sultan Qaboos University Hospital, Oman

Objectives: The aim of this study was to describe the pattern of viral infections in infants and children admitted to the Paediatric Intensive Care Unit (PICU) at Sultan Qaboos University Hospital (SQUH) in Muscat, Oman. Methods: A retrospective review of patient records was carried out on all patients admitted to the PICU between January 2011 and December 2012. In order to detect viruses, polymerase chain reaction (PCR) technology was used to detect viruses in nasopharyngeal aspirates, tracheal aspirates, plasma, stool and urine samples. All infants and children below 13 years old, who were admitted to the PICU at SQUH during the study period and with confirmed viral infections, were included in the study. Results: A total of 373 infants and children were admitted to the PICU during the study period. Viruses were detected in 34 patients. The most frequently detected viruses were cytomegalovirus (CMV) in 29.4%; this virus was noted predominantly in immuncompromised patients (80%, P = 0.023) and was associated with increased mortality (50%, P = 0.031) and prolonged PICU stay (70%, P = 0.045). Fatalities before discharge were recorded in 23.5% of the patients. The most frequent risk factors for viral infections were an age of <12 months old (47.1%), assisted ventilation/intubation (52.9%) and a prolonged PICU stay (55.9%). Conclusion: The results of this study found that CMV was the most common viral infection among infants and children admitted to the PICU in SQUH. CMV was also the leading cause of mortality
