Assessment of Infection Control, Practice Efficiency, and Health Economics of Sheathed Versus Standard Flexible Cystoscopy

The purpose of this research study is to compare the effectiveness and efficiency of using a sterile sheath (EndoSheath®) during cystoscopy versus a standard scope.

Study Overview

Detailed Description

The increasing costs in health care and enhanced infection control requirements necessitate the efficient and reliable use of frequently used techniques like cystoscopy. The health economics of cystoscopy are dependent on maintaining low levels of post-cystoscopy sequelae like urinary tract infection (UTI) and its potential precursors, significant asymptomatic bacteriuria and leukocytosis. Another key component of the economics and efficiency of cystoscopy is the time and cost related to the reprocessing of these devices in preparation for re-use. The use of disposable endoscope sheaths may limit the need for high level disinfection (HLD) between procedures and reduce reprocessing time and potentially prolong the cystoscope lifespan. The rationale for this study is to determine if a sheathed cystoscopy system would provide the desired cost and efficiency advantages compared to procedures done with non-sheathed cystoscopes. This is a prospective, randomized, parallel group, single center clinical trial to assess the clinical outcomes, practice efficiency and health economics of the use of sheathed cystoscopes (EndoSheath® System) compared to using standard (non-sheathed) cystoscopes. The study will evaluate the infection control (via the change in bacteriuria), clinical practice efficiency and costs of the EndoSheath technology with CST 5000 scope compared to standard cystoscopy with Olympus Visera Elite OTV-S190 digital flexible scope. There will be 30 subjects in the control group undergoing cystoscopy with the standard scope at the clinic, the Olympus Visera Elite, and 30 subjects in the study group undergoing cystoscopy with the EndoSheath system. The study is designed as a prospective, randomized controlled trial. There will be no active blinding of clinicians or subjects; however, it is anticipated that most subjects will be unaware of differences in the cystoscopy equipment that will be utilized in their routine procedures.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Number of Participants Who Had Post-Procedure Bacteriuria
Time Frame: 10-14 Days Post Procedure
The primary endpoint will be the change in bacteriuria pre- and post-procedure between EndoSheath CST-5000 cystoscope and standard (non-sheathed) Olympus Visera Elite OTV-S190 cystoscope during the course of routine clinical use in a urology clinic. The pre-procedure measurement of bacteriuria will occur on the day of the procedure. The post-procedure measurement of bacteriuria will occur approximately two weeks (10-14 days) post-procedure. This will be assessed by urine culture exams.
10-14 Days Post Procedure

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Number of Cystoscopes With Positive Bioburden Post-procedure.
Time Frame: Immediately after cystoscopy.
Immediately after completion of each cystoscopy procedure, the bioburden on the cystoscopes will be evaluated. The flexible cystoscope sheath was removed for bioburden assessment. For each cystoscope, whether sheathed or standard, two locations were assessed - the control body and the shaft. Cultures were obtained wiping the entire surface with sterile saline pledgets. The sample pledgets were placed in 1 ml sterile saline and shaken for 30 seconds. Ten drops of 0.02 ml aliquots from the sample were spotted on two 5% blood agar plates and incubated at 35°C in CO2.
Immediately after cystoscopy.
Total Time to Reprocess a Cystoscope
Time Frame: Beginning from the time a cystoscope is withdrawn from the urethral meatus at the end of a procedure until the completion of reprocessing, approximately 3,869 seconds
The total time required for a cystoscope to be reprocessed so that it is available for re-use in a subsequent procedure will be measured.
Beginning from the time a cystoscope is withdrawn from the urethral meatus at the end of a procedure until the completion of reprocessing, approximately 3,869 seconds
Subject Assessment of Procedure.
Time Frame: Approximately 2 min after the end of procedure.
After undergoing cystoscopy, patients will be asked to complete Visual Analog Scales (VAS) instruments to determine their level of pain experienced during cystoscopy as well as their perception of discomfort with the procedure. The score range is 0 to 100. Higher scores denotes worse outcomes.
Approximately 2 min after the end of procedure.
Staff Assessment of Cystoscope Reprocessing.
Time Frame: At the end of day of each procedure during 6 months
At the end of each day while the study is in progress, 6 members of the medical staff directly involved with the reprocessing of cystoscopes will evaluate the ease of reprocessing based on a 5-point Likert scale for the following parameters: ease of Insertion, ease of manipulation, optical quality, overall ease of use. The score range is 0 to 5. Higher score denotes better outcomes. A single value was derived per staff member and summarized for the group as a whole during 6 months.
At the end of day of each procedure during 6 months
Total Cost of Cystoscopy Reprocessing
Time Frame: 6 months
The health economics of reprocessing will be evaluated by associating personnel hourly costs with cystoscope reprocessing time segments. The total cost was averaged between pre-cleaning, cleaning, disinfection, rinsing, and drying for the 30 cystoscopes in each group for a duration of 6 months.
6 months
Number of Procedures Per Day Per Scope.
Time Frame: Per day.
Number of procedures per day per scope. On a daily basis urology outpatient clinic performs an average of 5 cystoscopies.
