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

AIMS: 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. BACKGROUND: 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. DESIGN: 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 3 months or longer was recruited. METHODS: Interviews were conducted using a narrative approach. Thirty-six interviews were conducted in England, Wales and Scotland between 2011-2013. RESULTS: Participants ranged in age from 22-96 years. 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. CONCLUSION: 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.

Drawing on Accounts of Long-Term Urinary Catheter Use: Design for the "Seemingly Mundane".

The design of the Foley catheter has not changed since 1937. Scientists interested in medical technology tend to focus on state-of-the-art designs for newsworthy specialties rather than the more mundane technologies of daily life. We interviewed 36 people living with a long-term urinary catheter in the United Kingdom, who described limitations of the current catheter design, including infections and complications and consequences for social life and relationships, and their perceptions of whose responsibility it was to improve the design. All took steps to hide the urine bag, but the need to use a catheter and urine bag had, for some, a very detrimental effect on social life and relationships. People living with long-term catheters are relatively isolated at home and dealing with many different underlying health problems, undermining opportunities to speak with a collective patient voice. Qualitative health researchers could act as a conduit to help stimulate new designs.

Comparing transurethral and suprapubic catheterization for long-term bladder drainage: a qualitative study of the patients' perspective.

PURPOSE: To explore why men and women decide to have a suprapubic catheter, how the decision is made, and to compare people's experiences of suprapubic and transurethral catheterization for long-term bladder drainage. DESIGN: Narrative interviews followed by thematic analysis. SUBJECTS AND SETTING: Thirty-six long-term catheter users living in England, Wales, or Scotland were interviewed. The sample included men and women from various socioeconomic backgrounds, with a wide range of conditions. They were aged 22 to 96 years (M = 57 years). METHODS: Interviews lasted between 1 and 3 hours; they were audiotaped and fully transcribed for analysis. A qualitative interpretive approach was taken, combining thematic analysis with constant comparison. RESULTS: Some respondents were satisfied with or preferred a urethral catheter; others preferred a suprapubic catheter because they perceived that suprapubic catheters led to fewer infections, were more hygienic, more comfortable, improved self-image, allowed a sense of control, and were better suited for sexual relations. Participants also mentioned the decision-making process, including how the decision was made to have a suprapubic catheter and where to insert the catheter at a particular point in the abdomen. Even with a suprapubic catheter, some worried about sex or were put off sexual intimacy because of the catheter. CONCLUSION: Our findings suggest that patients should be better informed before a suprapubic catheter is inserted and that issues such as sex should be raised in consultations when appropriate.

An indwelling urinary catheter for the 21st century.

What's known on the subject? and What does the study add? A vast literature has been published on the prevalence, morbidity and microbiology of catheter-associated urinary tract infections. Research and development in recent years has focused on producing antibacterial coatings for the indwelling Foley catheter with insufficient attention to its design. This article provides a critical examination of the design of the indwelling Foley catheter. Design specifications are outlined for a urine collection device that should reduce the vulnerability of catheterised urinary tract to infection. The indwelling urinary catheter is the most common cause of infections in hospitals and other healthcare facilities [1]. As long ago as 1958, Paul Beeson [2] warned '… the decision to use this instrument should be made with the knowledge that it involves the risk of producing a serious disease which is often difficult to treat'. Since then, scientific studies have progressed revealing a greater understanding of the bladder's defence mechanisms against infection and how they are undermined by the Foley catheter [3-5]. In addition, the complications caused by the development of bacterial biofilms on catheters have been recognised and the ways in which these bacterial communities develop on catheters have become clear [5,6]. It is now obvious that fundamental problems with the basic design of the catheter, which has changed little since it was introduced into urological practice by Dr Fredricc Foley in 1937 [7], induce susceptibility to infection. These issues need to be addressed urgently if we are to produce a device suitable for use in the 21st century.

Developing a strategy to reduce the high morbidity of patients with long-term urinary catheters: the BioMed catheter research clinic.

OBJECTIVE: To assess the idea of managing patients having problems with long-term catheterization (LTC, normally used when all other methods of bladder management have failed or are unsuitable) in a dedicated clinic, to present a prospective analysis of consecutive new patients attending between February 2002 and October 2006, and to establish the incidence of bladder stones in patients who have recurrent catheter encrustation and blockage. PATIENTS AND METHODS: Patients treated with LTC are a large heterogeneous group, mainly consisting of elderly people who have chronic disabilities, and catheter-associated complications occur in > 70% of them. In all, 260 consecutive new patients having problems with LTC were assessed; the evaluation consisted of basic demographics, a detailed history, clinical examination, urine analysis and flexible cystoscopy (FC) via the catheterization route. Patients with bladder stones were screened with FC for recurrence of stones at 3, 6 and 12 months after treatment. RESULTS: In all, 117 men and 143 women (mean age 67.7 years, range 23-97) were assessed; 147 (55.5%) had catheter encrustation. FC showed that 66 of the 147 patients (45%) had bladder stones. Forty-eight patients (73%) were successfully treated at the same clinic appointment and their stones were removed with the help of a tip-less stone basket. Eighteen patients (27%) were referred for inpatient treatment of bladder stones under general anaesthesia. Twenty of 66 patients with bladder stones (30%) formed recurrent bladder stones at a mean (range) follow-up of 8.1 (3-18 months). In addition, 36 patients had successful insertion of suprapubic catheter (SPC) under local anaesthetic in the clinic, and 11 were referred for SPC insertion under general anaesthesia. Two patients were diagnosed with bladder transitional cell carcinoma. CONCLUSION: The introduction of a dedicated catheter clinic, equipped with facilities such as FC and a hoist, enables patients to be treated in an environment that meets their needs and potentially reduces the risk of more complex stone removal and catheter problems at a later date. It can also act as a potential source of data for use in research and development. A significant proportion (45%) of patients with catheter encrustation and blockage had formed bladder stones. Our study provides a rationale for FC of all such patients to detect and remove stones.

Urinary catheters: history, current status, adverse events and research agenda.

For more than 3500 years, urinary catheters have been used to drain the bladder when it fails to empty. For people with impaired bladder function and for whom the method is feasible, clean intermittent self-catheterization is the optimal procedure. For those who require an indwelling catheter, whether short- or long-term, the self-retaining Foley catheter is invariably used, as it has been since its introduction nearly 80 years ago, despite the fact that this catheter can cause bacterial colonization, recurrent and chronic infections, bladder stones and septicaemia, damage to the kidneys, the bladder and the urethra, and contribute to the development of antibiotic resistance. In terms of medical, social and economic resources, the burden of urinary retention and incontinence, aggravated by the use of the Foley catheter, is huge. In the UK, the harm resulting from the use of the Foley catheter costs the National Health Service between £1.0-2.5 billion and accounts for ∼2100 deaths per year. Therefore, there is an urgent need for the development of an alternative indwelling catheter system. The research agenda is for the new catheter to be easy and safe to insert, either urethrally or suprapubically, to be retained reliably in the bladder and to be withdrawn easily and safely when necessary, to mimic natural physiology by filling at low pressure and emptying completely without damage to the bladder, and to have control mechanisms appropriate for all users.

Randomised controlled trial of pelvic floor muscle exercises and manometric biofeedback for erectile dysfunction.

BACKGROUND: The pelvic floor muscles are active in normal erectile function. Therefore, it was hypothesised that weak pelvic floor muscles could be a cause of erectile dysfunction. AIMS: To compare the efficacy of pelvic floor muscle exercises and manometric biofeedback with lifestyle changes for men with erectile dysfunction. DESIGN OF STUDY: Randomised controlled trial. SETTING: The Somerset Nuffield Hospital, Taunton, United Kingdom. METHOD: Fifty-five men with erectile dysfunction (median age 59.2 years; range 22-78 years) were enrolled from a local urology clinic. Of these, 28 participants were randomised to an intervention group and engaged in pelvic floor exercises, as well as receiving biofeedback and suggestions for lifestyle changes. Twenty-seven controls were solely advised on lifestyle changes. Baseline, 3- and 6-month assessments were: erectile function domain of International Index of Erectile Function (IIEF), Partner's International Index of Erectile Function (PIIEF), Erectile Dysfunction-Effect on Quality of Life (ED-EQoL), anal manometry, digital anal measurements, and clinical assessment by an assessor blind to treatment allocation. After 3 months, the control group were transferred to the active arm. RESULTS: At 3 months, compared with controls, men in the intervention group showed significant mean increases in the erectile function domain of the IIEF (6.74 points, P = 0.004); anal pressure (44.16 cmH(2)O, P <0.001); and digital anal grades (1.5 grades, P <0.001). All showed further improvement in these outcomes at 6 months. Similar benefits were seen in men of the control arm after transfer to active treatment. A total of 22 (40.0%) participants attained normal function, 19 (34.5%) participants had improved erectile function, and 14 (25.5%) participants failed to improve. CONCLUSION: Pelvic floor muscle exercises and biofeedback are an effective treatment for men with erectile dysfunction.

Pelvic floor exercises for treating post-micturition dribble in men with erectile dysfunction: a randomized controlled trial.

PURPOSE: The purpose of this trial was to compare the efficacy of pelvic floor muscle exercises and manometric biofeedback for post-micturition dribble (PMD) in men with erectile dysfunction. METHODS: Fifty-five men with erectile dysfunction (median age 59.2 years; range 22-78) were enrolled from a local urology clinic. Twenty-eight subjects were randomized to an intervention group and received pelvic floor muscle exercises including a strong post-void "squeeze out" pelvic floor muscle contraction, biofeedback, and suggestions for lifestyle changes. Twenty-seven control subjects were solely advised on lifestyle changes. The PMD status, anal manometry, and digital anal muscle grade were assessed at baseline, 3, and 6 months. After 3 months, the control group received the intervention with pelvic floor muscle exercises and biofeedback. Both groups were followed for an additional 3 months of home exercises. An independent assessor who was blinded to the grouping assessed the PMD status of subjects at 3 and 6 months. RESULTS: Thirty-six (65.5%) of the 55 subjects reported PMD at baseline. At 3 months, there was significant reduction in PMD after intervention (p=0.001) compared to the control subjects (p=0.102). In both groups combined after 3 months of pelvic floor muscle exercises and 3 months of home exercises, 27 (75%) subjects became asymptomatic of PMD, 3 (8.3%) improved, 5 (13.9%) dropped out, and 1 (2.8%) subject still reported PMD. PMD was not correlated to age, erectile function, anal manometric pressure, or digital anal muscle grade. CONCLUSION: Pelvic floor muscle exercises including a post-void "squeeze out" pelvic floor muscle contraction are an effective treatment for post-micturition dribble in men with erectile dysfunction.

A pilot study of users' experiences of urinary catheter drainage bags.

Despite the wealth of literature focused on the management of people living in the community with long-term indwelling urinary catheters, little attention has been paid to their impact on daily life. In a pilot study, a purposive sample of people with long-term indwelling urinary catheters were sent a questionnaire asking about their indwelling urinary catheter, method of drainage and impact of the catheter drainage bag on their daily life. Nearly one-quarter of respondents stated that wearing a drainage bag had a major impact on their normal daily living. The study also highlighted a number of methodological issues that need to be addressed in future research.

Flexible cystoscopy: outpatients or domiciliary?

The cost of caring for people in the community with long-term indwelling catheters varies widely but represents a significant amount of NHS spending. A rapid access catheter clinic was established at a Bristol hospital, for people experiencing difficulties with their long-term catheters, to facilitate prompt assessment and treatment. Many patients were found to be severely disabled with mobility problems and relied on hospital transport to attend the clinic for flexible cystoscopy. As a consequence the concept of undertaking this procedure on a domiciliary basis was introduced with a view to cutting costs, improving time management and offering a more reliable service to patients. A prototype battery-powered flexible cystoscope was developed to facilitate this service and five visits were undertaken. Feedback from patients indicated a preference for the domiciliary service and cost benefits were identified. As a result of these initial experiences, we are now planning a pilot study to establish the feasibility and costs of providing a domiciliary service on a permanent basis and gather qualitative data from patients on quality-of-life issues.

Prospective study of individuals with long-term urinary catheters colonized with Proteus species.

OBJECTIVES: To characterize the variability in the times catheters take to block with encrustation in patients who have Proteus in their urinary flora, and to identify factors responsible for modulating the rate of catheter encrustation and blockage. PATIENTS AND METHODS: Twenty patients were followed prospectively for > or = 12 weeks, with a bacteriological analysis on weekly urine samples. The pH of the voided urine samples and the pH at which crystals formed in them (the nucleation pH) were determined. Catheters were collected and examined for bacterial biofilm and crystal deposition. RESULTS: The time that catheters took to block was 2-98 days. The mean pH of the urine voided by patients designated as slow encrusters (6.9) was not significantly different (P = 0.237) from that of rapid encrusters (7.2). However, patients whose catheters took longer to block had a significantly higher mean nucleation pH (8.1 vs 7.3, P = 0.002) and significantly higher mean safety margin between their nucleation pH and voided pH (1.17 pH units vs 0.13, P = 0.003). CONCLUSION: The variation in the rate of catheter encrustation between individuals infected with Proteus is a function of the difference between the voided pH and the nucleation pH of their urine. The value of nucleation pH of an individual's urine varies widely, suggesting it should be possible to devise strategies to increase this value and thus reduce the rate of encrustation in those with urinary tract colonization by urease-positive bacteria.

Factors affecting crystal precipitation from urine in individuals with long-term urinary catheters colonized with urease-positive bacterial species.

Weekly urinalysis was conducted for 12 weeks on a group of 21 long-term catheter users with confirmed catheter encrustation and urinary tract colonization with urease-positive bacteria, in order to explore the cause of considerable variation in the severity of encrustation between sufferers. The rapidity of catheter blockage correlated significantly with the pH above which crystals precipitated from urine (the nucleation pH) but not the pH of the voided urine itself. Linear regression showed the nucleation pH to be significantly predicted by a combination of urinary calcium and magnesium concentrations, with calcium being the more influential variable. Reducing the rate of catheter encrustation could be achieved by lowering the urinary concentration of calcium and magnesium, which may only require catheter users to increase their fluid intake.

A clinical assessment of the performance of a sensor to detect crystalline biofilm formation on indwelling bladder catheters.

OBJECTIVES: To test the ability of a sensor developed to signal infection by the organisms that generate the crystalline biofilms that encrust catheters, to give an early warning that encrustation was occurring on patients' catheters, as the care of many patients undergoing long-term bladder catheterization is complicated by the encrustation and blockage of their catheters. PATIENTS AND METHODS: Twenty patients were followed prospectively for the lifetime of one of their catheters. Sensors based on cellulose acetate/bromothymol blue were placed in the urine-collection bags, which were changed as usual at weekly intervals. The bacteriology was assessed and pH determined weekly on urine samples. Photographic records were made of the sensors twice weekly. On removal, each catheter was examined for encrustation and blockage. RESULTS: Proteus mirabilis was not isolated from five patients and in these cases the sensor colour remained golden-yellow to brown. The catheters drained for the scheduled period and showed no signs of encrustation. By contrast, the sensors turned dark blue/black in the urine of all 15 patients infected with P. mirabilis. All these patients' catheters were encrusted and in 12 the catheters blocked. The mean interval between the sensor signalling and the catheter blocking was 12 days. CONCLUSION: The cellulose acetate/bromothymol blue sensors placed in the urine collection bags are capable of signalling infection by P. mirabilis. They also signal the early stages of catheter encrustation and allow catheter replacement in ample time to avoid the clinical crises and emergency referrals caused by catheter blockage.

Pelvic floor exercises for erectile dysfunction.

OBJECTIVE: To examine the role of pelvic floor exercises as a way of restoring erectile function in men with erectile dysfunction. PATIENTS AND METHODS: In all, 55 men aged > 20 years who had experienced erectile dysfunction for > or = 6 months were recruited for a randomized controlled study with a cross-over arm. The men were treated with either pelvic floor muscle exercises (taught by a physiotherapist) with biofeedback and lifestyle changes (intervention group) or they were advised on lifestyle changes only (control group). Control patients who did not respond after 3 months were treated with the intervention. All men were given home exercises for a further 3 months. Outcomes were measured using the International Index of Erectile Function (IIEF), anal pressure measurements and independent (blinded) assessments. RESULTS: After 3 months, the erectile function of men in the intervention group was significantly better than in the control group (P < 0.001). Control patients who were given the intervention also significantly improved 3 months later (P < 0.001). After 6 months, blind assessment showed that 40% of men had regained normal erectile function, 35.5% improved but 24.5% failed to improve. CONCLUSION: This study suggests that pelvic floor exercises should be considered as a first-line approach for men seeking long-term resolution of their erectile dysfunction.
