RESUMO
OBJECTIVES: Recent research suggests that the gender of health care providers may affect their medical performance. This trial investigated (1) the effects of the gender composition of resuscitation teams on leadership behaviour of first responders and (2) the effects of a brief gender-specific instruction on leadership behaviour of female first responders. METHODS: This prospective randomised single-blinded trial, carried out between 2008 and 2016, included 364 fourth-year medical students of two Swiss universities. One hundred and eighty-two teams of two students each were confronted with a simulated cardiac arrest, occurring in the presence of a first responder while a second responder is summoned to help. The effect of gender composition was assessed by comparing all possible gender-combinations of first and second responders. The gender-specific instruction focused on the importance of leadership, gender differences in self-esteem and leadership, acknowledgement of unease while leading, professional role, and mission statement to lead was delivered orally for 10 min by a staff physician and tested by randomising female first responders to the intervention group or the control group. The primary outcome, based on ratings of video-recorded performance, was the first responders' percentage contribution to their teams' leadership statements and critical treatment decision making. RESULTS: Female first responders contributed significantly less to leadership statements (53% vs. 76%; P = 0.001) and critical decisions (57% vs. 76%; P = 0.018) than male first responders. For critical treatment decisions, this effect was more pronounced (P = 0.007) when the second responder was male. The gender-specific intervention significantly increased female first responder's contribution to leadership statements (P = 0.024) and critical treatment decisions (P = 0.034). CONCLUSIONS: Female first responders contributed less to their rescue teams' leadership and critical decision making than their male colleagues. A brief gender-specific leadership instruction was effective in improving female medical students' leadership behaviours.

OBJECTIVES: Little is known about the influence of gender on resuscitation performance which may improve future education in resuscitation. The aim of this study was to compare female and male rescuers in regard to cardiopulmonary resuscitation and leadership performance. DESIGN: Prospective, randomized simulator study. SETTING: High-fidelity patient simulator center of the medical ICU, University Hospitals Basel (Switzerland). SUBJECTS: Two hundred sixteen volunteer medical students (108 females and 108 males) of two Swiss universities in teams of three. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: We analyzed data on the group and the individual level separately. The primary outcome on the group level was the hands-on time within the first 180 seconds after the onset of the cardiac arrest. Compared with male-only teams, female-only teams showed less hands-on time (mean ± SD) (87 ± 41 vs 109 ± 33 s; p = 0.037) and a longer delay before the start of chest compressions (109 ± 77 vs 70 ± 56 s; p = 0.038). Additionally, female-only teams showed a lower leadership performance in different domains and fewer unsolicited cardiopulmonary resuscitation measures compared with male-only teams. On the individual level, which was assessed in mixed teams only, female gender was associated with a lower number of secure leadership statements (3 ± 2 vs 5 ± 3; p = 0.027). Results were confirmed in regression analysis adjusted for team composition. CONCLUSIONS: We found important gender differences, with female rescuers showing inferior cardiopulmonary resuscitation performance, which can partially be explained by fewer unsolicited cardiopulmonary resuscitation measures and inferior female leadership. Future education of rescuers should take gender differences into account.

OBJECTIVE: The influence of teaching leadership on the performance of rescuers remains unknown. The aim of this study was to compare leadership instruction with a general technical instruction in a high-fidelity simulated cardiopulmonary resuscitation scenario. DESIGN: Prospective, randomized, controlled superiority trial. SETTING: Simulator Center of the University Hospital Basel in Switzerland. SUBJECTS: Two-hundred thirty-seven volunteer medical students in teams of three. INTERVENTION: During a baseline visit, the medical students participated in a video-taped simulated witnessed cardiac arrest. Participants were thereafter randomized to receive instructions focusing either on correct positions of arms and shoulders (technical instruction group) or on leadership and communication to enhance team coordination (leadership instruction group). A follow-up simulation was conducted after 4 mos. MEASUREMENTS AND MAIN RESULTS: The primary outcome was the amount of hands-on time, defined as duration of uninterrupted cardiopulmonary resuscitation in the first 180 secs after the onset of the cardiac arrest (hands-on time) [corrected]. Secondary outcomes were time to start cardiopulmonary resuscitation, total leadership utterances, and technical skills. Outcomes were compared based on videotapes coded by two independent researchers. After a balanced performance at baseline, the leadership instruction group demonstrated a longer hands-on time (120 secs; interquartile range, 98-135 vs. 87 secs; interquartile range, 61-108; p < .001), a shorter median time to start cardiopulmonary resuscitation (44 secs; interquartile range, 32-62; vs. 67 secs; interquartile range, 43-79; p = .018), and had more leadership utterances (7; interquartile range, 4-10; vs. 5; interquartile range, 2-8; p = .02) in the follow-up visit. The rate of correct arm and shoulder positions was higher in teams with technical instruction (59%; 19 out of 32; vs. 23%; 7 out of 31; p = .003). CONCLUSIONS: Video-assisted leadership and technical instructions after a simulated cardiopulmonary resuscitation scenario showed sustained efficacy after a 4-mo duration. Leadership instructions were superior to technical instructions, with more leadership utterances and better overall cardiopulmonary resuscitation performance.
