To decrease the number of unexpected in-hospital cardiac arrest cases, some hospitals have introduced rapid response systems (RRS). However, this has not necessarily decreased in- hospital cardiac arrests. We investigated hospitalized cases that made emergency calls in a hospital without RRS and consider what is necessary for the introduction of RRS. The participants were 66 hospitalized adults who were subject to an emergency call for resuscitation between January 2012 and September 2015. The participants were also divided into two groups by presence or absence of abnormal vital signs (heart rate, blood pressure, respiratory rate, sudden neurological change) before the ‘emergency call’ was made. There were no significant differences in the number of cardiopulmonary arrest cases at the time of the ‘emergency call’, ICU admission cases, or 30 days death cases between the two groups. We found 30 cases where the respiratory rate was not monitored, including 24 cases (66.7%) in the group with no abnormal signs and six cases (20.0%) in the group with abnormal signs ( p ‹ 0.001).The above suggests that abnormal signs before an emergency call were often overlooked, because respiratory rates were not measured. It is important to monitor the respiratory rate as a component of an effective RRS.
