Clinical Trial Summary

A bicentric, open-label randomised controlled trial (RCT) is planned to investigate whether the use of fitness wristbands in a defined preoperative period prior to radical cystectomy leads to a preoperative increase in participants' physical activity (number of steps per day) up to the day of radical cystectomy.

Description:

The goal of the PreAct study is to test whether the use of fitness wristbands in a defined preoperative period prior to radical cystectomy with a daily activity goal and feedback on the achievement of this goal improves the participants' physical activity up to the day of radical cystectomy. In addition to the fitness tracker, we provide each patient with a smartphone. For each fitness tracker a separate account in a fitness application is set up for (e.g. name: tracker1.0 with the corresponding e-mail address and password). Neither the patients in the Daily activity Goal and Feedback arm nor the No Daily Activity Goal or Feedback arm receive the access data to the accounts. However, the patients in the intervention group receive the access PIN for the smartphone. On this smartphone a messaging service and the fitness application are installed. The patient thus receives, for example the wristband tracker1.0, which is registered with the corresponding access data in the fitness application of the smartphone given to them. For the entire preoperative period, the Bluetooth function on the smartphone must always stay activated so that the fitness application and the fitness tracker are continuously connected to each other. A detailed description of the timing and implementation of the intervention are described in "Study design" and "Arm and Interventions".

Eligibility

Inclusion Criteria:

• Planned radical cystectomy with bilateral pelvic lymphadenectomy and one of the different forms of urinary diversion (continent vs. incontinent; orthotopic vs. heterotopic) in patients with bladder cancer
• Participants age = 18 years and capacity to consent
• Mobile participant who is not dependent on a walking aid
• The participant declares his or her consent to participate in this study by signing and dating the informed consent form prior to the surgical procedure

Exclusion Criteria:

• Karnofsky performance status scale = 70% (with 70%: Care for self. Unable to carry on normal activity or to do active work (Ambulatory and capable of all selfcare but unable to carry out any work activities). ) (Range: 0 - 100 percent with 0 percent "participant´s death" and 100 percent "no disabilities"
• ASA Physical Status Classification: ASA > 3 (3: A patient with severe systemic disease)
• ASA 1, 2, 3 if acute or chronic diseases of the musculoskeletal system or the central nervous system are involved that result in a symptomatic restriction of motor and / or, in the last case, neurological function (healing ruptures and fractures, Parkinson's disease, multiple sclerosis, etc.)
• Emergency intervention

Related Conditions & MeSH terms

• Bladder Cancer
• Bladder Neoplasm
• Bladder Urothelial Carcinoma
• Urinary Bladder Neoplasms

Intervention

Device:
• Daily Activity Goal and Feedback
The daily activity target is a fixed number of steps. The exact number of steps is determined beforehand as part of the case number planning in a pilot study with ten participants and adjusted if necessary. The activity target we suggest is 8000 steps. In addition, the participants receive feedback several times a day about the steps needed to reach the goal and whether they have ultimately reached the daily goal.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of steps per day	Average daily step count measured by the fitness tracker during the period of prehabilitation 7 to 10 days before surgery.	Participants' daily step count is recorded on the day of surgery when the fitness tracker is put down.
Secondary	Total number of steps	Total number of steps measured by the fitness tracker during the period of prehabilitation 7 to 10 days before surgery.	Participants' total number of steps is recorded on the day of surgery when the fitness tracker is put down.
Secondary	Postoperative physical activity	The postoperative physical activity of the participants measured by the average number of steps per day and in total on postoperative days 1 to 3. Neither arm will receive a daily activity goal. However, the fitness trackers of the No Daily Activity Goal or Feedback arm are still covered.	Morning of postoperative day 4 at 7 PM
Secondary	Postoperative Complications	Postoperative complications measured by the Comprehensive Classification Index (CCI), on a scale from 0 (no complications) to 100 (death), (Slankamenac, Graf et al. 2013) and the Clavien-Dindo Classification (CDC), which consists of 7 grades (I, II, IIIa, IIIb, IVa, IVb and V), the first one indicating any deviation from the normal postoperative course, the highest grade indicating death (Clavien, Barkun et al. 2009): CDC = 3a corresponding to a CCI = 26.2 defined as "severe complications" including CDC = 5 and CCI = 100 defined as "patient's death" and the total number of complications	On postoperative day 30 and 90
Secondary	Operating time	In minutes, incision - surgical incision closure	On the day of surgery
Secondary	Blod loss	In millilitres	On the day of surgery
Secondary	Required transfusion of blood products	Number of red blood cell concentrates, platelet concentrates, frozen fresh plasma	On the day of surgery
Secondary	Feasibility of the planned urinary diversion	Yes or no	On the day of surgery
Secondary	Conversion rate	If the planned urinary diversion is not feasible	On the day of surgery
Secondary	Patient Reported Outcome Measures (PROMs)	SF-36: Health-related quality of life (Scale 0 - 100: The higher the score, the lower the disability. A score of 100 corresponds to no disability)	On the day of randomization at the premedication appointment and on the day of discharge which is on average 2 weeks after the surgery and postoperative day 30 and 90
Secondary	Length of hospital stay (LOS)	LOS measured by the number of days spent in the hospital after surgery until discharge	On the day of discharge which is on average 2 weeks after the surgery
Secondary	Readmission rate	Readmissions due to a complication of the radical cystectomy	On postoperative day 90 if occured
Secondary	Reoperation rate	Reoperation due to a complication of the radical cystectomy	On postoperative day 90 if occured
Secondary	Length of stay in the intensive care unit (ICU)	Days spent in the ICU after surgery	On postoperative day 90 if occured
