Outpatient appointment non-attendance and unplanned health care for children and young people with neurological conditions: a retrospective cohort study.

<bold>Aim: </bold>To test the hypothesis that children and young people with neurological conditions who missed outpatient appointments have more emergency inpatient admissions and Accident and Emergency centre (A&E) visits than those who missed none.<bold>Method: </bold>Retrospective cohort of individuals aged up to 19 years with neurological conditions, identified from routine hospital data in England, UK from April 1st, 2003 to March 31st, 2015 using an International Statistical Classification of Diseases and Related Health Problems, coding framework. Counts of emergency inpatient admissions and A&E visits per person per year were modelled (random intercept negative binomial regression) with outpatient attendance the independent variable of interest.<bold>Results: </bold>The cohort numbered 524 613 individuals. Those who missed outpatient appointments had 19 per cent (95% confidence interval [CI] 18-19) more emergency inpatient admissions and 16 per cent (95% CI 15-17) more A&E visits per year than those who missed none. 'Did not attends' had a larger increase in unplanned health care than patient or provider cancellations. If no appointments were missed, the models predict there would have been 107 000 fewer A&E visits from 2007/2008 to 2014/2015 and 104 000 fewer emergency inpatient admissions from 2003/2004 to 2014/2015.<bold>Interpretation: </bold>Missed outpatient appointments were associated with increased unplanned health care. Improving outpatient attendance may have the potential to reduce emergency inpatient admissions and A&E visits.<bold>What This Paper Adds: </bold>Missed outpatient appointments by children and young people with neurological conditions are associated with increased unplanned health care. Both emergency inpatient admissions and Accident and Emergency centre visits are increased. 'Did not attends' are more strongly associated with unplanned health care than cancellations.
