Validation of "patient-reported outcomes via online questionnaire" as a urinary continence assessment and quality improvement tool following radical prostatectomy.

Securing reliable data on functional outcomes following radical prostatectomy (RP) is paramount to patient follow-up and management.

To validate an email-based patient-reported outcomes tracking system in assessing pad-free continence rates and time-to continence recovery following RP.

483 men undergoing RP by a single surgeon from November 2013 to March 2019 were prospectively assigned to 1 of 3 tracking systems: 1) a preaddressed paper packet containing a pad-free card and daily urinary pad log, (N = 249); 2) an automated email questionnaire, (N = 234) or 3) both (N = 51). Patients tracked electronically received electronic Research Electronic Data Capture surveys 30 days after catheter removal, with up to 3 reminders sent automatically if no response was received within 2 days. Response rates and continence rates were compared in group 1 vs. group 2 via student t-tests; time-to pad-free status was assessed for concordance among men in group 3 via linear regression.

Thirty-day response rates in group 1 (paper) vs. group 2 (electronic) were 80.7% (201/249) and 94.0% (220/234), (P < 0.0001); pad-free rates were 64.2% (129/201) and 64.1% (141/220), (P = 0.9847), respectively. Similarly, 1-year response rates in group 1 and 2 were 87.6% (218/249) vs. 94.0% (220/234), (P = 0.0146); pad-free rates were 91.7% (200/218) vs. 96.4% (212/220), (P = 0.0411), respectively. In group 3, time to pad-free continence recovery assessed via Patient Reported Outcomes via Online Questionnaire (PROVOQ) was highly concordant in 89.6% (43/48) of patients ± 5 days (Figure 1, R2 = 0.9893). No significant bias was found for subsequent reporting in either group.

The use of automated email survey questionnaires via PROVOQ for the assessment of patient-reported post-RP continence recovery facilitates increased response rates, timeliness of response, and accuracy. PROVOQ significantly reduce the labor of tracking continence outcomes, improve quality improvement efforts, and enables surgeons to more clearly differentiates risk of long-term incontinence.
