Study on the factors related to not attempting resuscitation for out-of-hospital cardiac arrest / 中华急诊医学杂志

ABSTRACT

Objective:To explore the epidemiological factors of patients with OHCA who did not attempt CPR, and analyze the reasons and clinical features of non resuscitation.Methods:Data from OHCA patients who did not undergo CPR were collected from January 2020 to December 2020 at Beijing Emergency Medical Center. The registration form was designed according to the Utstein model, and the data were analyzed retrospectively by the chi-square test.Results:A total of 5 977 patients were enrolled and divided into two groups according to age: 2 349 patients aged ≤ 80 years old and 3 628 patients aged ≥ 81 years old. Compared with the younger group, the proportion of patients in the older group who did not undergo CPR due to disease (97.0%) and family desertion (99.4%) were higher, and the difference was statistically significant (both P<0.01). Conclusions:Elderly people over 80 years old with underlying diseases have a high probability of developing OHCA at home. Most of the witnesses at the scene were family members and could not implement CPR in time. After the emergency personnel arrived at the scene, they found that the patient had been in cardiac arrest for too long and had apparently died. Family members would choose to give up treatment.
