Background and ObjectivesChildren with tracheostomies are at increased risk of tracheostomy‐related complications and require extra care. Standardized training programs for caregivers can improve tracheostomy care and reduce complications. In this study, we compared caregiver knowledge and skill scores after a standardized theoretical and practical training program on tracheostomy care (IStanbul PAediatric Tracheostomy (ISPAT) project) immediately and 1 year post‐training and evaluated how this training affected the children's clinical outcomes.Materials and MethodsWe included 32 caregivers (31 children) who had received standardized training a year ago and administered the same theoretical and practical tests 1 year after training completion. We recorded tracheostomy‐related complications and the number and reasons for admission to the healthcare centers. All data just before the training and 1 year after training completion were compared.ResultsAfter 1 year of training completion, the median number of correct answers on the theoretical test increased to 16.5 from 12 at pretest (p < 0.001). Compared with pretest, at 1‐year post‐training practical skills assessment scores, including cannula exchange and aspiration, were significantly higher (both p < 0.001) and mucus plug, bleeding, and stoma infection reduced significantly (p = 0.002, 0.022, and 0.004, respectively). Hands‐on‐training scores were better than pretest but declined slightly at 1 year compared to testing immediately after training. Emergency admission decreased from 64.5% to 32.3% (p = 0.013). Hospitalization decreased from 61.3% to 35.5% (p = 0.039).ConclusionOur findings indicate that caregiver training can lead to a persistent increase in knowledge and skill for as long as 1 year, as well as improvements in several measurable outcomes, although a slight decrease in scores warrants annual repetitions of the training program.
