Standardised traditional outcome measures may fail to address factors that are important to patients and address irrelevant factors. Aim of this study was to assess patient-reported goals and goal achievement (GA) in the antimuscarinic treatment for overactive bladder (OAB) patients. Men and women aged ≥ 18 years with OAB symptoms were eligible for the study. Treatment began with a dose of 10 mg oxybutynin, to be increased if necessary to 30 mg. Before treatment, each patient's primary treatment goal was identified. After 12-week treatment, patients reported GA using a Likert scale from 0 (no achievement) to 5 (complete achievement). Successful achievement was defined as a score of 4 or 5. Traditional outcome measures including voiding diaries, the OAB questionnaire short form, patient perception of bladder condition, and treatment benefit and satisfaction were assessed. Baseline characteristics affecting GA and the correlation between GA and traditional outcome measures were evaluated. A total of 303 goals were identified from 303 patients (51 men, 252 women). Of those, 72.3% addressed symptom relief and frequency as the most common target symptom. Other goals addressed were improving quality of life (13.5%) and eliminating coping behaviours (14.2%). After treatment, 42% had a successful GA with a median score of 3 (interquartile range; 2-4). Age had a negative effect on GA. Goal achievement was the outcome measure most correlated with treatment benefit and satisfaction. Goal achievement can be a valuable outcome measure in OAB patients, addressing individual treatment goals and reflecting treatment benefit and patient satisfaction.
