Purpose:
Shared decision making (SDM) is ideally suited to abdominal wall surgery in older adults given the breadth of decision making required by the hernia surgeon and the impact on quality of life (QOL) by various treatment options. Given the paucity of literature surrounding SDM in hernia patients, the feasibility of a novel, formalized SDM aid/tool was evaluated in a pilot randomized trial.
Methods:
Patients 60 years or older with a diagnosed ventral hernia were prospectively randomized at an academic hernia center. In the experimental arm, a novel SDM tool, based on the SHARE Approach, guided the consultation. Previously validated SDM assessments and patient's hernia knowledge retention was measured.
Results:
Eighteen (18) patients were randomized (9 control and 9 experimental). Cohorts were well matched in age (p = 0.51), comorbidities (Charlson Comorbidity Score: p = 0.43) and frailty (mFI-11: p = 0.19; Risk Analysis Index: p = 0.33). Consultation time was 11 min longer in the experimental cohort (p < 0.01). There was a trend towards better Decisional Conflict Scores in the experimental group (p = 0.25) and the experimental cohort had improved post-visit retained hernia knowledge (p < 0.01). All patients in the experimental arm (100%) enjoyed working through the SDM aid/tool and felt it was a worthwhile exercise.
Conclusion:
Incorporating a formalized SDM tool into a busy hernia surgical practice is feasible and well received by patients. In addition, early results suggest it improves retention of basic hernia knowledge and may reduce patient's decisional conflict. Next steps include condensing the SDM tool to enhance efficiency within the clinic and beginning a large, randomized control trial.
