When routine becomes stressful: A qualitative study into resuscitation team members' perception of stress and performance.

Interprofessional teamwork is of high importance during stressful situations such as CPR. Stress can potentially influence team performance. This study explores the perception of stress and its stressors during performance under pressure, to be able to further adjust or develop training. Healthcare professionals, who are part of the resuscitation team in a large Dutch university medical center, discussed their experiences in homogeneous focus groups. Nine focus groups and one individual interview were conducted and analyzed thematically, in order to deepen our understanding of their experiences. Thematic analysis resulted in two scenarios, routine and stress and an analysis of accompanying team processes. Routine refers to a setting perceived as straightforward. Stress develops in the presence of a combination of stressors such as a lack of clarity in roles and a lack of knowledge on fellow team members. Participants reported that stress affects the team, specifically through an altering of communication, a decrease in situational awareness, and formation of subgroups. This may lead to a further increase in stress, and potentially result in a vicious cycle. Team processes in a stressful situation like CPR can be disrupted by different stressors, and might affect the team and their performance. Improved knowledge about the stressors and their effects might be used to design a training environment representative for the performance setting healthcare professionals work in. Further research on the impact of representative training with team-level stressors and the development of a "team brain" might be worthwhile.

Termination of resuscitation in out-of-hospital cardiac arrest in women and men: An ESCAPE-NET project.

AIM: Women have less favorable resuscitation characteristics than men. We investigated whether the Advanced Life Support Termination of Resuscitation rule (ALS-TOR) performs equally in women and men. Additionally, we studied whether adding or removing criteria from the ALS-TOR improved classification into survivors and non-survivors. METHODS: We analyzed 6,931 female and 14,548 male out-of-hospital cardiac arrest (OHCA) patients from Dutch and Swedish registries, and validated in 10,772 female and 21,808 male Danish OHCA patients. Performance measures were calculated for ALS-TOR in relation to 30-day survival. Recursive partitioning analysis was performed with the ALS-TOR criteria, as well as age, comorbidities, and additional resuscitation characteristics (e.g. initial rhythm, OHCA location). Finally, we explored if we could reduce the number of ALS-TOR criteria without loss of prognostic value. RESULTS: The ALS-TOR had a specificity and positive predictive value (PPV) of ≥99% in both women and men (e.g. PPV 99.9 in men). Classification by recursive partitioning analysis showed a high sensitivity but a PPV below 99%, thereby exceeding the acceptable miss rate of 1%. A combination of no return of spontaneous circulation (ROSC) before transport to the hospital and unwitnessed OHCA resulted in nearly equal specificity and PPV, higher sensitivity, and a lower transport rate to the hospital than the ALS-TOR. CONCLUSION: For both women and men, the ALS-TOR has high specificity and low miss rate for predicting 30-day OHCA survival. We could not improve the classification with additional characteristics. Employing a simplified version may decrease the number of futile transports to the hospital.
