A Novel Patient Decision Aid for Surrogate Decision Makers of Comatose Survivors of Cardiac Arrest

Not Applicable

Completed

• Conditions: Cardiac Arrest With Successful Resuscitation
• Interventions: Other: Decision Aid for Surrogate Decision Makers of Comatose Survivors of Cardiac Arrest

• Registration Number: NCT03908346
• Lead Sponsor: University of Colorado, Denver

Brief Summary

This study will test the feasibility and acceptability of deploying a decision aid for surrogate decision makers of comatose survivors of cardiac arrest early during hospitalization. This decision aid is to inform, educate and support decision makers charged with determining goals of care during post-cardiac arrest treatment.

Detailed Description

Survival and neurological recovery after out-of-hospital cardiac arrest are highly variable, driven in part by inconsistent hospital care following successful resuscitation. International guidelines for post-cardiac arrest care recommend delaying neurologic prognostication until 72-hours after resuscitation because early prognostication is imprecise and may precipitate inappropriate withdrawal of life sustaining therapy (WLST). Early WLST has been observed in-post cardiac arrest care. In order to encourage better guideline concordant care, the study proposes the implementation of an educational tool to support and inform surrogate decision makers in post-cardiac arrest care and neuro-prognostication. This pilot study will test the feasibility of implementing an educational tool for surrogate decision makers, the acceptability of such an intervention and early measures of knowledge translation. This study will inform the creation of a randomized controlled trial to test the ability of the tool to encourage guideline concordant timing of post-cardiac arrest neuro-prognostication.

Arm && Interventions

Group	Intervention	Description
Decision Aid for Surrogate Decision Makers	Decision Aid for Surrogate Decision Makers of Comatose Survivors of Cardiac Arrest	In this pilot trial all participants will be presented with the decision aid and queried as to the feasibility, acceptability and knowledge translation that is gained by exposure to the decision aid

Primary Outcome Measures

Name	Time	Method
Effectiveness - Knowledge	Through study completion, on average 2.5 years	Determine the number of individuals who reviewed the educational tool and completed the follow up knowledge evaluation. The pre-knowledge and post-knowledge/acceptability surveys will establish how effective the tool was at relaying information to the surrogate decision maker.
Adoption	Through study completion, on average 2.5 years	To maximize adoption, 8-10 qualitative interviews will be conducted with emergency medicine providers, nurses and ancillary staff to explore barriers to use and potential adaptations to the implementation that might improve real world use. Providers who did not deploy the device will be included in order to understand their reasons for not adopting the intervention. Surrogate decision makers who did not agree to participate in the pilot intervention will be queried to understand their reasons for non-participation.
Reach	Through study completion, on average 2.5 years	To establish Reach, the investigators will determine the following: (1) number of out-of hospital cardiac arrests that present to the University of Colorado Hospital (UCH) ED; (2) number of Out of Hospital Cardiac Arrest (OHCA) patients with family/surrogate decision makers in the ED; (3) number of surrogate decision makers who agree to participate. Establishing reach is integral as it will allow us to determine the feasibility of intervening in the ED and will characterize the difficulties enrolling decision makers. The research assistant will keep a running tabulation of these data.
Implementation	Through study completion, on average 2.5 years	In order to assess implementation (and prepare for larger implementation) a work-flow analysis will be conducted of the post-cardiac educational tools within the UCH ED. Nurses, ancillary staff (chaplain, social worker) who participate in family meetings within the emergency department will be queried. Via work-flow analysis, an understanding will be gained about when the tool was deployed, potential barriers/facilitators to deployment and how to best implement in a busy ED.

Secondary Outcome Measures

Name	Time	Method
Effectiveness - Patient Outcomes	Through study completion, on average 2.5 years	As a secondary outcome, outcomes data for the cardiac arrest patients will be measured. These data will include the disposition, including withdrawal of life sustaining therapy, survival, or re-arrest.
Effectiveness - Decision Quality	Through study completion, on average 2.5 years	We will measure decision regret using the Ottawa decision Regret Scale, decision conflict, emotional distress using promis measures and self efficacy using a validated scale derived for surrogate decision makers. This data will measure decision quality as a result of the tool.
