Trial Outcomes & Findings for The Influence of Default Options in Advance Directives (NCT NCT01346176)

NCT ID: NCT01346176

Last Updated: 2016-02-03

Results Overview

The primary outcome variable will be the proportion of subjects that select palliative care options compared to the those who request aggressive treatment in each study arm. We will analyze the effects of manipulating default options and delays in alerting subjects to the presence of multiple default options on each selection in the ADs in order to see how default options influence decisions on general treatment goals and instructions for specific procedures.

Participant Flow

Recruitment took place in outpatient clinics at the Pereleman Center for Advanced Medicine at the University of Pennsylvania. Recruitment occurred from May 2010 - Feb 2012. No recruitment occurred between Oct 2010 - Jan 2011 while the first research nurse transitioned responsibilities to the second research nurse.

9,378 patients were assessed for eligibility. 9,246 were excluded. 8,299 did not meet inclusion criteria, 391 already had an advance directive, 322 were either missed in clinic, cancelled their appointments, or were hospitalized, 181 declined participation, 43 had their participation deferred by their physician

PRIMARY outcome

Timeframe: 6 months

Population: This number was based on the number of participants who returned completed advance directive forms in each group

The primary outcome variable will be the proportion of subjects that select palliative care options compared to the those who request aggressive treatment in each study arm. We will analyze the effects of manipulating default options and delays in alerting subjects to the presence of multiple default options on each selection in the ADs in order to see how default options influence decisions on general treatment goals and instructions for specific procedures.

SECONDARY outcome

Timeframe: Two months after AD completion

Population: These numbers reflect the number of patients who completed and returned and advance directive as well as completed a satisfaction interview and questionnaire with a research associate.

Patients' satisfaction with their advance care planning was assessed two months after they completed their ADs. One of two authors blinded to patients' group assignments contacted patients by phone and administered a satisfaction survey based on the Canadian Healthcare Evaluation Project (CANHELP) questionnaire. This thirteen-item questionnaire has been validated for assessing satisfaction with end-of-life care planning. Patients were asked to indicate satisfaction with various parts of advance care planning (e.g. decisions about the use of life sustaining technologies including CPR or cardiopulmonary resuscitation, breathing machines, and dialysis) on a scale from 1 to 5, where 1 means not at all satisfied and 5 means completely satisfied. The overall average across the 13 item scale in each group is presented in the results below.
