Quality of Life After Treatment for Bladder Cancer: The Bladder Cancer Survivorship Study

Change in quality of life outcomes - PROMIS-29

Assessed using the Patient-Reported Outcomes Measurement Information System (PROMIS)-29, a 29-item instrument with 29 questions in eight categories of Health Related Quality of Life (HRQOL): physical function, sleep disturbance, pain interference and pain intensity, fatigue, anxiety, depression) and ability to participate in social roles and activities. Questions are answered on a 5-point scale with varying responses assigned to the scale based on the category/question.

Time frame: At baseline, 6, 12, 24, and 36 months

Change in quality of life outcomes - Bladder Cancer Index

Assessed using the Bladder Cancer Index (BCI). The BCI consists of 36 items, with 4- or 5-point Likert response scales for each item, covering 3 primary domains: urinary (14 items), bowel (10 items), and sexual (12 items). The items focus on the frequency of the disease symptoms, with answer scales such as: "Never, rarely, about half the time, usually, or always".

Time frame: At baseline, 6, 12, 24, and 36 months

Patient level characteristics

Will be assessed by the effect of race/ethnicity, comorbid conditions, education level, gender, and age on patient reported outcomes. Interactions between intervention type and patient-level characteristics will be included. The distributions of variables will be summarized graphically and numerically.

Time frame: At baseline, 6, 12, 24, and 36 months after treatment
