Practice Problem: There was a report of an existing practice problem of increased 30-day readmission rates in medically complex children at an outpatient clinic within an extensive hospital system. Hospital readmissions can cause clinical, social, and financial burdens to the patients and their families and thus reflected a need for interventions to reduce readmissions. PICOT: The PICOT question that guided this change project: In medically complex pediatric patients ages 0-17, what is the effect of a discharge intervention bundle in reducing all-cause 30-day hospital readmissions compared to current practice within an 8-week timeframe? Evidence: The literature revealed 18 pertinent studies that fit the inclusion and exclusion criteria that promoted a discharge intervention bundle. The themes within the evidence included post-discharge telephone calls, follow-up appointments, medication reconciliation, and education with teach-back to reduce overall readmission rates. Intervention: The evidence-based intervention utilized the bundle of post-discharge telephone calls within 72 hours, follow up appointments within 7 days, and medication reconciliation with education and teach-back through in-person and virtual care. The clinic nurses championed the intervention and tracked all the data using a check sheet. Outcome: Evaluation of the outcome measures confirmed a decrease in all-cause 30-day readmissions from 23% to 14.5% within the project timeframe. Implications of the findings support the existing evidence for implementing a multifaceted bundle to decrease readmissions. Conclusion: The evidence-based change project decreased all-cause 30-day readmissions rates. The results of the project proved that implementing consistent discharge standards in medically complex children helped guide medical staff, improved patient outcomes, saved costs to the organization, and reduced 30-day all-cause hospital readmissions.
