Decision coaching to prepare patients for making health decisions: a systematic review of decision coaching in trials of patient decision AIDS

Abstract

Background: Decision coaching is individualized, nondirective facilitation of patient preparation for shared decision making.

Purpose: To explore characteristics and effectiveness of decision coaching evaluated within trials of patient decision aids (PtDAs) for health decisions.

Data sources: A subanalysis of trials included in the 2011 Cochrane Review of PtDAs.

Study selection: Eligible trials allowed the effectiveness of decision coaching to be compared with another intervention and/or usual care.

Data extraction: Two reviewers independently screened 86 trials, extracted data, and appraised quality.

Data synthesis: Ten trials were eligible. Decision coaching was provided by genetic counselors, nurses, pharmacists, physicians, psychologists, or health educators. Coaching compared with usual care (n = 1 trial) improved knowledge. Coaching plus PtDA compared with usual care (n = 4) improved knowledge and participation in decision making without reported dissatisfaction. Coaching compared with PtDA alone (n = 4) increased values-choice agreement and improved satisfaction with the decision-making process without any difference in knowledge or participation in decision making. Coaching plus PtDA compared with PtDA alone (n = 4) had no difference in knowledge, values-choice agreement, participation in decision making, or satisfaction with the process. Decision coaching plus PtDA was more cost-effective compared with PtDA alone or usual care (n = 1).

Limitations: Methodological quality, number of trials, and description of decision coaching.

Conclusions: Compared with usual care, decision coaching improved knowledge. However, the improvement in knowledge was similar when coaching was compared with PtDA alone. Outcomes for other comparisons are more variable, some trials showing positive effects and other trials reporting no difference. Given the small number of trials and variability in results, further research is required to determine the effectiveness of decision coaching.
