A study protocol of a comparative mixed study of the T-Control catheter.

ABSTRACT

Background: Foley catheters have been subject to limited development in the last few decades. They fulfil their basic function of draining urine from the bladder but cause other associated problems. T-Control is a new silicone Foley catheter with an integrated fluid control valve whose design aims to reduce the risks associated with bladder catheterization by a multifactorial approach. The general purpose of this study is to determine the effectiveness, comfort, and experience of the patient catheterized with T-Control® compared with patients with a conventional Foley catheter. Study Design: This trial is a mixed-method study comprising a two-arm, pilot comparative study with random allocation to T-Control catheter or traditional Foley catheter in patients with long-term catheterization and a study with qualitative methodology, through discussion groups. Endpoints The comfort and acceptability of the T-Control® device (qualitative) and the quality of life related to self-perceived health (quantitative) will be analysed as primary endpoints. As secondary endpoints, the following will be analysed magnitude and rate of infections (symptomatic and asymptomatic); days free of infection; indication of associated antibiotic treatments; determination of biofilm; number of catheter-related adverse events; use of each type of catheterization's healthcare resources; and level of satisfaction and workload of health professionals. Patients and Methods: Eligible patients are male and female adults aged ≥18 years, who require a change of long-term bladder catheter. The estimated sample size is 50 patients. Patient follow-up includes both the time of catheter insertion and its removal or change 4 weeks later, plus the time until the discussion groups take place.
