Hospitalized patients' attitudes towards participating in a randomized control trial in case of a cardiac arrest.

BACKGROUND: No previous study has evaluated patients attitudes towards inclusion in an ongoing cardiac arrest clinical trial. The aim of this study was to assess patientś willingness and motives to participate in the ongoing randomized controlled drug trial "Vasopressin and Steroids in addition to Adrenaline in cardiac arrest" (VAST-A trial) in case of an in-hospital cardiac arrest (IHCA).

OBJECTIVES: Hospitalized patients, men ≥ 18 and women ≥ 50 years, were asked for informed consent for inclusion in the VAST-A trial in case of an IHCA, the reason for approving or declining inclusion in the trial and baseline characteristics.

METHODS: Patients admitted to hospital were asked to give informed consent of inclusion in VAST-A in case of an IHCA during their hospital stay. Patients were also asked why they approved or declined inclusion as well as baseline characteristics questions.

RESULTS: 1,064 patients were asked about willingness to participate in the VAST-A trial, of these 902 (84.8%) patients approved inclusion. A subgroup of 411 patients were, except willingness, also asked about motives to participate or not and basic characteristics. The main reason for approving inclusion was to contribute to research ( n  = 328, 83.9%). The main reason for declining inclusion was concerns regarding testing the drug treatment ( n  = 6, 30%).

CONCLUSION: Among hospitalized patients the vast majority gave informed consent to inclusion in an ongoing randomized cardiac arrest drug trial. The main reason for approving inclusion was to contribute to research.
