Introduction Clinical experience suggests that some radical prostatectomy (RP) patients have unrealistic expectations with regard to their long-term sexual function. This study was undertaken to assess the understanding of patients who had previously undergone RP with regard to their postoperative sexual function. Methods Patients presenting within 3 months of their RP (open and robotic) were questioned regarding the sexual function information that they had received pre-operatively. Patients were questioned about erectile function, postoperative ejaculatory status, orgasm and postoperative penile morphology changes. Statistical analyses were performed to assess for differences between patients who underwent open versus robotic RP. Results 336 consecutive patients (from 9 surgeons) with a mean age of 64±11 years had the survey instrument administered (216 underwent open and 120 underwent robotic RP). No significant differences existed in patient age or comorbidity profiles between the two groups. Only 38% of men had an accurate recollection of their nerve sparing status. The mean (SD) elapsed time post-RP at the time of postoperative assessment was 3 (2) months. Robotic RP patients expected shorter EF recovery time (6 vs 12 months, p=0.02), a higher likelihood of recovery back to baseline erectile function (75 vs. 50%, p=0.01), and lower potential need for ICI (4 vs. 20%, p=0.01). Almost half of all patients were unaware that they were rendered anejaculatory by their surgery. None of the robotic RP patients and only 10% of open RP patients recalled being informed of the potential for penile length loss (p<0.01) and none were aware of the association between RP and Peyronie’s disease. Conclusions Patients who have undergone RP have largely unrealistic expectations with regard to their postoperative sexual function.

“…In another study, patients who were counseled by their doctor on risk of stroke associated with foregoing carotid endarterctomy exhibited very poor recall of this information. The mean recalled stroke risk was 57% compare to actual mean risk of 22% [19]. One explanation for the limited efficacy of numerical descriptions of risk may be “fuzzy trace theory” [20].…”

Objective To determine which formats communicate medication adherence effectively to patients. Methods HIV-infected adults on antiretrovirals viewed examples of refill data in 5 formats: (1) percentage of doses, (2) number of days late to refill (“days late”), (3) calendar of days with/without medications, (4) pie chart of days with/without medications, and (5) letter grade. Five scenarios (>95%, 90–95%, 80–90%, 70–80% and <70% adherence) were presented in each format. Participants rated scenarios on adherence improvement needed. “Good understanding” was ≥4 of 5 scenarios correct. We calculated odds ratios for “good understanding” using logistic regression with percentage as the referent format. Results 124 participants were median age 48.5, 65% Black, 71% male. Understanding of all formats differed by education (all interaction p values<0.02). For ≤12 years education, odds ratios (OR) of understanding (95% CI) compared to percentage were: days late 3.3 (2.3–4.7), calendar 3.1 (2.2–4.3) pie chart 2.0 (1.4–2.7), and letter grade 1.8 (1.3–2.5) For >12 years education, ORs were: days late 1.3 (0.9–2.0), calendar 2.4 (1.5–3.8), pie chart 2.9 (1.8–4.6), and letter grade 1.7 (1.1–2.6). Calendar plot was most preferred. Conclusions Adherence percentage was the least understood format regardless of education. Practice Implications Calendars should be used to convey adherence information.
