Abstract
Shared decision-making is a strategy to assist with patient involvement in medical decisions. One of its pillars is patient knowledge and understanding of the risks and benefits associated with specific procedures. We studied patient knowledge about transradial (TRA) and transfemoral (TFA) cardiac catheterization. A prospective study was conducted in 100 patients hospitalized following diagnostic and therapeutic cardiac catheterization-TRA in 71% of patients and remaining TFA. All patients were presented a standard balanced informed consent outlining risks and benefits. Following catheterization, patients were verbally administered an 11-item open-ended questionnaire to assess knowledge of cardiac catheterization and the associated risks and benefits. A patient knowledge index (PKI) was developed with 1 point given for: identifying the procedure; correctly describing the procedure; identifying at least 1 risk of TRA; and/or TFA; and at least 1 benefit of TRA; and/or TFA. Maximum PKI score was 6. The mean PKI score was 2.6 ± 1.1. A PKI score ≥4 was observed in 21% of patients with only 1 patient obtaining the maximum 6 points. Over 80% of patients were unable to recall procedure risks provided at the time of informed consent. The majority of patients were unable to discriminate between TRA and TFA risks and benefits, PKI 2.52 versus 2.60, respectively (p = 0.718). On multivariate analysis, higher education levels were correlated with increased PKI scores (odds ratio = 0.65, p = 0.014) whereas black race was associated with lower PKI scores (odds ratio = -0.48, p = 0.045). In conclusion, patient retention of information from the informed consent was low. The majority of patients had no preference or deferred to their physician's expertise when deciding TRA compared with TFA. This study identifies challenges with implementing shared decision-making and the need for improved patient education and involvement regarding cardiac catheterization.
