Objectives
To understand factors affecting nurses' attitudes towards the Therapeutic Hypothermia after Pediatric Cardiac Arrest (THAPCA) trials and association with approach/consent rates.
Design, setting and participants
Cross sectional survey of pediatric/cardiac intensive care nurses' perceptions of the trials, conducted at 16 of 38 self-selected study sites.
Measurements
The primary outcome was the proportion of nurses with positive perceptions, as defined by agree or strongly agree with the statement “I am happy to take care of a THAPCA patient”. Associations between perceptions and study approach/consent rates were also explored.
Results
Of 2241 nurses invited, 1387 (62%) completed the survey and 77% reported positive perceptions of the trials. Nurses, who felt positively about the scientific question, the study team, and training received, were more likely to have positive perceptions of the trials (p <0.001). Nurses who had previously cared for a research patient had significantly more positive perceptions of THAPCA compared with those who had not (79% vs. 54%, p<0.001). Of the 754 nurses who cared for a THAPCA patient, 82% had positive perceptions, despite 86% reporting it required more work. Sixty-nine percent believed that hypothermia reduces brain injury and mortality; sites had lower consent rates when their nurses believed that hypothermia was beneficial. Institution-specific approach rates were positively correlated with nurses' perceptions of institutional support for the trial (r=0.54, p=0.04), intensive care unit support (r=0.61, p=0.02), and the importance of conducting the trial in children (r=0.61, p=0.01).
Conclusions
The majority of nurses had positive perceptions of the THAPCA trials. Institutional, colleague and study team support and training were contributing factors. Despite increased work, nurses remained enthusiastic demonstrating that studies with intensive bedside nursing procedures are feasible. Institutions whose nurses believed hypothermia was beneficial had lower consent rates suggesting that educating nurses on study rationale and equipoise may enhance study participation.
