ObjectivesIt remains unclear whether computer-assisted instruction (CAI) is more effective than other teaching methods in acquiring and retaining ECG competence among medical students and residents.DesignThis systematic review and meta-analysis followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.Data sourcesElectronic literature searches of PubMed, databases via EBSCOhost, Scopus, Web of Science, Google Scholar and grey literature were conducted on 28 November 2017. We subsequently reviewed the citation indexes for articles identified by the search.Eligibility criteriaStudies were included if a comparative research design was used to evaluate the efficacy of CAI versus other methods of ECG instruction, as determined by the acquisition and/or retention of ECG competence of medical students and/or residents.Data extraction and synthesisTwo reviewers independently extracted data from all eligible studies and assessed the risk of bias. After duplicates were removed, 559 papers were screened. Thirteen studies met the eligibility criteria. Eight studies reported sufficient data to be included in the meta-analysis.ResultsIn all studies, CAI was compared with face-to-face ECG instruction. There was a wide range of computer-assisted and face-to-face teaching methods. Overall, the meta-analysis found no significant difference in acquired ECG competence between those who received computer-assisted or face-to-face instruction. However, subanalyses showed that CAI in a blended learning context was better than face-to-face teaching alone, especially if trainees had unlimited access to teaching materials and/or deliberate practice with feedback. There was no conclusive evidence that CAI was better than face-to-face teaching for longer-term retention of ECG competence.ConclusionCAI was not better than face-to-face ECG teaching. However, this meta-analysis was constrained by significant heterogeneity amongst studies. Nevertheless, the finding that blended learning is more effective than face-to-face ECG teaching is important in the era of increased implementation of e-learning.PROSPERO registration numberCRD42017067054.

IntroductionAlthough ECG interpretation is an essential skill in clinical medicine, medical students and residents often lack ECG competence. Novel teaching methods are increasingly being implemented and investigated to improve ECG training. Computer-assisted instruction is one such method under investigation; however, its efficacy in achieving better ECG competence among medical students and residents remains uncertain.Methods and analysisThis article describes the protocol for a systematic review and meta-analysis that will compare the effectiveness of computer-assisted instruction with other teaching methods used for the ECG training of medical students and residents. Only studies with a comparative research design will be considered. Articles will be searched for in electronic databases (PubMed, Scopus, Web of Science, Academic Search Premier, CINAHL, PsycINFO, Education Resources Information Center, Africa-Wide Information and Teacher Reference Center). In addition, we will review citation indexes and conduct a grey literature search. Data extraction will be done on articles that met the predefined eligibility criteria. A descriptive analysis of the different teaching modalities will be provided and their educational impact will be assessed in terms of effect size and the modified version of Kirkpatrick framework for the evaluation of educational interventions. This systematic review aims to provide evidence as to whether computer-assisted instruction is an effective teaching modality for ECG training. It is hoped that the information garnered from this systematic review will assist in future curricular development and improve ECG training.Ethics and disseminationAs this research is a systematic review of published literature, ethical approval is not required. The results will be reported according to the Preferred Reporting Items for Systematic Review and Meta-Analysis statement and will be submitted to a peer-reviewed journal. The protocol and systematic review will be included in a PhD dissertation.PROSPERO registration numberCRD42017067054; Pre-results.

Aim To describe the long‐term health outcomes of children admitted to a paediatric intensive care unit. Methods A systematic review of the literature was performed. Studies of children under 18 years of age admitted to a paediatric intensive care unit were included. Studies focussed on neonatal admissions and investigating specific paediatric intensive care unit interventions or admission diagnoses were excluded. A table was created summarising the study characteristics and main findings. Risk of bias was assessed using the Newcastle Ottawa Quality Assessment Scale for observational studies. Primary outcome was short‐, medium‐ and long‐term mortality. Secondary outcomes included measures of neurodevelopment, cognition, physical, behavioural and psychosocial function as well as quality of life. Results One hundred and eleven studies were included, most were conducted in high‐income countries and focussed on short‐term outcomes. Mortality during admission ranged from 1.3 to 50%. Mortality in high‐income countries reduced over time but this trend was not evident for lower income countries. Higher income countries had lower standardised mortality rates than lower income countries. Children had an ongoing increased risk of death for up to 10 years following intensive care admission as well as increased physical and psychosocial morbidity compared to healthy controls, with associated poorer quality of life. Conclusions There is limited high‐level evidence for the long‐term health outcomes of children after intensive care admission, with the burden of related morbidity remaining greater in poorly resourced regions. Further research is recommended to identify risk factors and modifiable factors for poor outcomes, which could be targeted in practice improvement initiatives.
