Characteristics of In-Hospital Patients with Congenital Heart Disease Requiring Rapid Response System Activations: A Japanese Database Study

Objectives: This study aimed to the characteristics of in-hospital deterioration in patients with congenital heart disease who required rapid response system activation and identify risk factors associated 1-month mortality. Methods: We retrospectively analysed data from a Japanese registry 35 participating hospitals. included consecutive between January 2014 March 2018. Logistic regression analyses were performed examine associations mortality other patient-specific variables. Results: Among 9,607 for whom was activated, only 82 (0.9%) had disease. Only few being treated at cardiology cardiovascular surgery departments (12.3% 9.9%, respectively). Moreover, incidences rapid-response events after intensive care unit discharge or low (6.8% 12.2%, The most common reason respiratory dysfunction (desaturation: 35.4%, tachypnoea: 25.6%, new dyspnoea: 19.5%). Rapid interventions transfers 65.9% 20.7% patients, respectively. rate 1.2% end intervention 11.0% 1 month. decreased increased adjusted odds ratio 1.10 (95% confidence interval 1.02–1.19) 1.02 interval, 1.00–1.04 rate, Conclusions: systems rarely activated cardiac discharge, which situations high sudden Therefore, encouraging use these will enable by third, specialised team emergencies help provide comprehensive medical patients. Furthermore, vital signs activation. These findings may guide treatment selection showing deterioration.
