Study Type: Observational
Study Design: Observational Model: Case-Crossover
Time Perspective: Retrospective
Official Title: CSP #476CC - Enhancing Quality of Informed Consent (EQUIC-CC) Customized Consent

Further study details as provided by Department of Veterans Affairs:

Primary Outcome Measures:
  • improve method of disclosing information to patients in the informed consent process [ Time Frame: post-randomization ] [ Designated as safety issue: No ]

Estimated Enrollment: 240
Study Start Date: April 1999
Study Completion Date: April 1999
Primary Completion Date: April 1999 (Final data collection date for primary outcome measure)

Detailed Description:

Intervention: (1) Cognitive stratification (obtained by a test of cognitive ability, followed by a tailored IC process); (2) Pre-recruitment video (a patient-activation video designed to prevent several common misconceptions; (3) Provide prospective research volunteers with a sense of the purpose and methods of controlled research); and (4) Evaluation of the informed consent process using the Brief Informed Consent Evaluation Protocol (BICEP) developed in EQUIC-DP.

Primary Hypothesis: The validity of informed consent can be improved, as measured by an independent interview of patients (BICEP), by at least one of three interventions described above.

Primary Outcomes: The quality of the informed consent process, as measured by the BICEP (Brief Informed Consent Evaluation Protocol). The BICEP also offers a method to certify informed consent in routine use.

Study Abstract: Customized Consent will develop and test an innovative, supplemental method of disclosing information to patients in the informed consent process. This disclosure strategy is intended to increase patients' understanding and satisfaction with the consent process. This study has two goals:

  • to evaluate the effectiveness of an intervention to improve comprehension during informed consent; and
  • to identify those patients for whom this intervention is most effective.

The primary goal of EQUIC-CC is to determine whether an intervention, added to usual procedures for obtaining informed consent, is able to improve comprehension. The second goal of EQUIC-CC is to identify those patients for whom an augmented consent intervention is most effective, as well as to determine which subgroups of patients, if any, are most likely to benefit from visual information added to the usual disclosure phase of obtaining informed consent.
