Grade 3 school performance among children born preterm: a population-based cohort study.

OBJECTIVE: To study the association between prematurity and grade 3 school performance in a contemporary cohort of children. METHODS: Population-based retrospective cohort study in Manitoba, Canada. Children born between 1999 and 2011 who had their grade 3 school performance data available were eligible. Preterm birth (<37 weeks) was the exposure of interest assessed using multivariable logistic regression models. Our primary outcomes were 'needs ongoing help' or 'outside the range' in at least two of each of the (1) four numeracy and (2) three reading competencies. RESULTS: Of the 186 956 eligible children, 101 436 children (7187 preterm (gestational age, median (IQR) 35 weeks (34, 36)) and 94 249 term (40 weeks (39,40)) were included. Overall, 19% of preterm and 14% of term children had the numeracy outcome (adjusted OR (aOR) 1.38; 95% CI 1.29 to 1.47, p<0.001), while 19% and 13% had the reading outcome (aOR 1.38; 1.29 to 1.48, p<0.001). These differences showed a gestational age gradient. Gestational age (for numeracy, <28 weeks aOR 4.93 (3.45 to 7.03), 28-33 weeks 1.72 (1.50 to 1.98), 34-36 weeks 1.24 (1.15 to 1.34); for reading, <28 weeks 3.51 (2.40 to 5.14), 28-33 weeks 1.72 (1.49 to 1.98), 34-36 weeks 1.24 (1.17-1.37)), male sex, small for gestational age and maternal medical and sociodemographic factors were associated with the numeracy and reading outcomes in this cohort. CONCLUSIONS AND RELEVANCE: Children born preterm had poorer performance in grade 3 numeracy and reading proficiencies than children born full term. All children born preterm, not just those born extremely preterm, should be screened for reading and numeracy performance in school and strategies implemented to address any deficits.

Living labs for patient engagement and knowledge exchange: an exploratory sequential mixed methods study to develop a living lab in paediatric rehabilitation.

INTRODUCTION: Despite recognition of the importance of patient engagement in research and knowledge translation, systematic approaches to engagement and co-ideation remain limited. Living labs are collaborative knowledge sharing systems that use multimethod, user-centred approaches that hold potential to catalyse these aims. However, their use in healthcare is limited, and no living lab has been developed in paediatric rehabilitation. In response to this gap and to propel innovative knowledge exchange, we propose a mixed methods study to co-develop a living lab prototype (ie, preliminary infrastructure with opportunity for scale up) in paediatric rehabilitation, with relevance to other healthcare contexts. METHODS: An exploratory sequential mixed methods study will be undertaken to determine research and knowledge exchange priorities and to inform the development of the living lab prototype. Stage 1: we will use a multipronged approach to sample 18-21 youth with developmental differences or rehabilitation needs, their youth siblings and parents/guardians from a provincial paediatric rehabilitation centre, to participate in qualitative and arts-based data collection. Data will provide insight into desirable features of the living lab. Stage 2: E-surveys to youth, siblings, parents/guardians and clinicians who receive or provide services at this same centre will expand on priorities and living lab features. Stage 3: integrated analysis will inform the living lab prototype development. ANALYSIS: Inductive thematic analysis using interpretive description, integrated analysis of visual data and descriptive and content analysis of e-survey data will be undertaken. Joint displays will facilitate data integration. Priorities will be identified using a modified rank-order method for each key living lab domain. ETHICS AND DISSEMINATION: Institutional ethics and site approval have been granted. A parent advisory group and rehabilitation engineering partners will confer on data and inform the development of the living lab prototype. User engagement with the prototype will occur during an online or in-person event, and findings shared through non-technical research summaries, journal articles and academic presentations.

Social communication features in children following moderate to severe acquired brain injury: a cross-sectional pilot study.

We compared the social communication deficits of children with moderate to severe acquired brain injury or autism spectrum disorder, while accounting for the role of attention-deficit hyperactivity disorder (ADHD) symptoms. Parents of 20 children aged 6 to 10 years (10 acquired brain injury; 10 autism spectrum disorder) completed the Social Communication Questionnaire, and Conners 3 Parent Short. A multivariate analysis of covariance revealed significant differences between groups in Social Communication Questionnaire restricted repetitive behavior scores, but not reciprocal social interaction or social communication. Multiple linear regressions indicated diagnosis did not predict reciprocal social interaction or social communication scores and that Conners 3 Parent Short Form hyperactivity scores were the strongest predictor of Social Communication Questionnaire reciprocal social interaction scores after accounting for age and Intelligence Quotient. The lack of difference in social communication deficits between groups may help in understanding the pathophysiology underlying the behavioral consequences of acquired brain injury. The link between hyperactivity and reciprocal interaction suggests that targeting hyperactivity may improve social outcomes in children following acquired brain injury.
