Perception about telemedicine services among parents of children with neurodevelopmental disorders in a specialised tertiary centre in Oman.

ABSTRACTWhile telemedicine has shown promise for diagnosis and treatment, its integration into specialised clinics and mainstream healthcare is slow. A study at Sultan Qaboos University Hospital, Oman, investigated parental perceptions of virtual clinics and telemedicine experiences among parents of children with neurodevelopmental disorders (NDD) conducted from January 2021 to January 2022; the cross-sectional study involved 130 participants. The study revealed that 70% of participants were male, and the mean age of the children was 6.1 ± 0.26 years. Regarding telemedicine awareness, 53% of respondents were informed, yet encountered obstacles such as poor internet service and lack of awareness. Despite challenges, 46% of respondents viewed telemedicine positively. Parents showed significant differences in their perception of virtual interviews based on interview purpose (P = 0.034), clinic type (P < 0.001), internet service quality (P = 0.029), timing conflicts (P = 0.001), lack of technology experience (P = 0.041), and awareness gaps (P = 0.012). Our study identified challenges for parents of children with NDD in utilising telehealth, primarily stemming from limited awareness and internet connectivity issues. To enhance telemedicine quality, we suggest improving internet infrastructure and promoting telemedicine awareness. Further research is needed to optimise telemedicine implementation for both diagnosis and intervention in children with NDD.

Applying whole exome sequencing in a consanguineous population with autism spectrum disorder.

This study aimed to systematically assess the impact of clinical and demographic variables on the diagnostic yield of Whole Exome Sequencing (WES) when applied to children with Autism Spectrum Disorder (ASD) from a consanguineous population. Ninety-seven children were included in the analysis, 63% were male and 37% were females. 77.3% had a suspected syndromic aetiology of which 68% had co-existent central nervous system (CNS) clinical features, while 69% had other systems involved. The diagnostic yield of WES in our cohort with ASD was 34%. Children with seizures were more likely to have positive WES results (46% vs. 31%, p = 0.042). Probands with suspected syndromic ASD aetiology showed no significant differential impact on the diagnostic yield of WES.

Intellectual Profile of Children with Autism Spectrum Disorder: Identification of verbal and nonverbal subscales predicting intelligence quotient.

OBJECTIVES: This study aimed to explore the intelligence quotient (IQ) profile among children with autism spectrum disorder (ASD) and identify the most important subscales that predict the IQ. The analysis of an intellectual profile with age and gender differentials and the identification of a battery of subscales of intelligence are important for clinical management of ASD among children and for facilitating placement for remedial and educational services. METHODS: Data were collected through an exploratory study of 100 children aged between three and 13 years, who were referred to the department of child health and development in Sultan Qaboos University Hospital, a tertiary hospital, in Oman between June 2016 and June 2019. RESULTS: Among the 100 participants of this study, 79% were male, resulting in a male-female ratio of 4:1. The mean of full-scale IQ was found to be 68.6 ± 18.1. Furthermore, the mean of nonverbal IQ (73.5 ± 17.5) was significantly higher than that of verbal IQ (65.5 ± 17.6). Finally, more than half (61%) of the children were observed to have had mild to moderate impairment in their IQ levels. CONCLUSIONS: Age and gender showed no significant association with IQ level. The regression analysis identified nonverbal fluid reasoning, nonverbal visual-spatial processing, nonverbal working memory and verbal knowledge as the significant predictors of total IQ. The crucial dimensions of verbal and nonverbal IQ identified in this study can be used to evaluate complicated cases.

Parental Age and the Risk of Autism Spectrum Disorder in Oman: A case-control study.

OBJECTIVES: This study aimed at evaluating advanced parental age as a risk factor for autism spectrum disorder (ASD) in an Omani cohort. METHODS: This case-control study compared 278 ASD cases with 722 gender-matched controls, retrieved from the electronic records of the Developmental Paediatric Clinic, Sultan Qaboos University Hospital, Muscat, Oman, between January 2015 and June 2016. RESULTS: Most ASD cases were male (76.6%) and mostly diagnosed between 3-4 years of age, with more than 50% of the cases originating from Muscat and Batinah governorates. Compared to controls, mothers from the case group had significantly higher educational levels (post-secondary education versus high school/no formal education: odds ratio [OR] = 1.62, 95% confidence interval [CI]: 1.197-2.192). In a multivariate logistic regression, the OR of maternal age as a risk for ASD increased dramatically with advancing age category (using age <25 as reference, OR = 3.39, 6.12, 7.86 and 13.13 for age categories 25-29, 30-34, 35-39 and ≥40 years, respectively). The ORs of advancing paternal age as a risk for ASD were also statistically significant (using age <30 as reference, OR = 2.20, 2.36 and 3.12 for age categories 30-34, 35-39 and 40-44 years, respectively); however, there was a drop in the effect with paternal age ≥45 years (OR = 1.42; 95% CI: 0.64-3.15). CONCLUSION: Both maternal and paternal increased age were associated with a higher risk of ASD; however, the association was more pronounced and more consistent with advanced maternal age compared to paternal age.

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.
