Introduction:
The implementation of the rapid response teams (RRTs) system in paediatrics was possible due to the participation of the Regional Specialized Children’s Hospital in Olsztyn, Poland in a project launched by the National Centre for Quality Assessment in Health Care in Cracow, Poland.

Aim:
Present a model of RRTs system and the effects of its implementation in child care.

Material and methods:
The medical staff survey (n = 97) analysis and complete analysis of the medical records of patients (document analysis; n = 1020) were performed. The variables such as: the number and the type of RRTs interventions, the number of patients admitted to the intensive care unit (ICU) and the hospital mortality rate were analysed. These were compared with the variables obtained before the implementation of RRTs (from 1^st November 2018 to 31^st August 2019 vs. 1^st November 2017 to 31^st August 2018).

Results and discussion:
RRTs made 626 surveillance visits to patients with serious conditions staying at hospital wards, 266 scheduled visits to 89 patients transferred from the ICU to other wards and 126 interventions in response to calls from different wards. The number of patients transferred from the hospital wards to the ICU decreased from 125 to 90. The number of deaths in the ICU decreased from 20 to 13.

Conclusions:
The evaluation of the 10-month implementation period for this project encourages to keep RRTs operational. The interviewed staff admitted that the safety of inpatient care increased along with more meticulous supervision over patients needing intensive care.
