Issues Related to the use of a Mobile Application of the Protocol for Preventing and Managing Urinary Catheter Blockage Among Long-term Indwelling Urinary Catheter Users for Visiting Nurses: An Interview Study of Visiting Nurses in Japan

Background: We developed a mobile application of the protocol for preventing and managing catheter blockage among long-term indwelling catheter users for visiting nurses. We conducted meetings at four visiting nurse stations in Japan from May to June 2017 to explain the application to visiting nurses. Objective: The purpose of the present study was to clarify issues related to the full-scale use of this protocol application, using data from focus group interviews with visiting nurses. Methods: We conducted focus group interviews with the meeting participants. The focus group interviews were conducted at four different venues. Three focus groups had eight participants, and the fourth had two participants, for a total of 26 study participants. Specifically, the group interviews covered (1) the application’s structure and content; (2) operability; (3) portability; (4) possibilities for use, effects, and expectations; and (5) concerns about use. Results: The results of the group interviews were classified into five categories: possibilities for the use of the mobile application, possibilities for further use of the application by nurses, suggestions for the use of the application by caregivers and nursing care workers, the burden associated with the use of the mobile application, and opinions and desires for improvements in the mobile application. Conclusion: The results suggested that visiting nurses would use the mobile application. However, for full-scale use, it would be necessary to add the ability to use accumulated data, increase the number of learning screens, and take safety management measures for the transmission of medical information.

Exploring the information needs of people living with a long-term indwelling urinary catheter: a qualitative study.

To explore the information needs of long-term indwelling urinary catheter users, the consequences for patients of inadequate information and how these needs could be met. Previous studies have drawn attention to the lack of information given to indwelling catheter users and how users would benefit from more. Little is known about the varied and detailed information needs of long-term indwelling catheter users. A qualitative interpretative approach was used, combining thematic analysis with constant comparison. A diverse sample of people living in the community with a catheter for 3months or longer was recruited. Interviews were conducted using a narrative approach. Thirty-six interviews were conducted in England, Wales and Scotland between 2011-2013. Participants ranged in age from 22-96years. After having a catheter fitted they wanted more technical information about it and information to help prevent catheter-related physical problems (infection, blockage, leaking), on sexual activity and the siting of catheters and about managing a social life with a catheter. In its absence, patients sometimes experimented with the catheter, learning to live with it through trial and error, used the Internet to find out more, or contacted other patients or organizations. Research has consistently shown that indwelling catheter users need to be given more information but some patients still feel poorly informed. Nurses are in a good position to find out what people know, what they need, and to ensure that patients have contact phone numbers for further information and details of reliable websites and support organizations.

A clinical evaluation of a sensor to detect blockage due to crystalline biofilm formation on indwelling urinary catheters

To test the performance and acceptability of an early warning sensor to predict encrustation and blockage of long-term indwelling urinary catheters. In all, 17 long-term indwelling catheter users, 15 'blockers' and two 'non-blockers' (controls) were recruited; 11 participants were followed prospectively until catheter change, three withdrew early and three did not start. Two sensors were placed in series between the catheter and the urine bag at catheter change. The sensor nearest the bag was changed at the same time as the bag change (weekly); the sensor nearest the catheter remained in situ for the duration of the catheter's life. Bacteriology and pH determinations were performed on urine samples at each bag, sensor and catheter change. The colour of the sensors was recorded daily. On removal, each sensor and the catheter were examined for visible evidence of encrustation and blockage. Participants were asked to keep a daily diary to record colour change and any other relevant observations and to complete a psychosocial impact of assistive devices tool at the end of the study. Participants and carers/healthcare professionals (when involved in urine bag or catheter change) were asked to complete a questionnaire about the sensor. Urease-producing bacteria were isolated from seven of the 14 patients (including early withdrawals; P. mirabilis in four, Morganella or Providencia in three). In six of the seven patients the sensors turned blue-black; two of these were early withdrawals, two went to planned catheter change (one of these was recruited as a 'non-blocker') and three had catheter blockage. The number of days of catheterisation before blockage was 22, 23 and 25 days, and the sensor changed colour within 24-48 h after insertion. The urine mean (range) pH of the sensors that turned blue-black was 7.6 (5.5-9.0) and of the sensors that remained yellow 6.1 (5.1-7.5). The sensor was generally well-received and was positive in the psychosocial assessment. The sensor is a useful indicator of urine pH and of the conditions that lead to catheter blockage. It may be particularly useful for new indwelling catheter users. To be a universally acceptable predictor of catheter blockage, the time from sensor colour change to blockage needs to be reduced.

Nurses' Advice Regarding Sterile or Clean Urinary Drainage Bags for Individuals With a Long-term Indwelling Urinary Catheter

The purpose of this study was to identify, compare, and explore advice nurses give to community-dwelling long-term indwelling catheter users on the use of sterile or clean urinary drainage bags, and to obtain information that would inform the design of a larger-scale international survey. A survey was targeted to nurse members of the International Continence Society (n = 130). Respondents (n = 28; 21.5%) included nurses from Australia, Canada, Belgium, Switzerland, the United Kingdom, and the United States, who specialized in managing incontinence. The project was conducted as a descriptive, exploratory pilot study. Respondents completed an online anonymous survey that was distributed by the International Continence Society. The survey instrument was designed by the investigators and comprised 14 questions with both fixed and open-ended response options. Most respondents in this survey advised indwelling catheter users to reuse their catheter bags (n = 15; 68%). Factors that influenced advice included concerns about the cost of catheter bags, an evaluation of the individual's infection risk, local and national policies, evidence-based guidelines, users' living arrangements, and their ability to clean the bags. Advice on decontamination methods varied; however, the most commonly recommended cleaning agent was water and vinegar, followed by a sterilizing or bleach solution or dishwashing detergent. Nurses play a key role in educating and supporting indwelling catheter users. Results of this study highlight variability in the advice nurses give to community-dwelling long-term indwelling catheter users about sterile or clean urinary drainage bags. This variability requires further investigation and affirms the need for a larger-scale study that draws on a broader sample of nurses.
