Evaluation of a modified sanitary napkin as a sample self-collection device for the detection of genital chlamydial infection in women. (1/23)

A modified sanitary napkin was compared with endocervical swab and urine specimens for the detection of urogenital Chlamydia trachomatis infection. Endocervical swabs and/or first-catch urine were collected from 510 women at medical or community settings in Quebec City. Participants were also asked to wear a modified sanitary napkin (Ezy-Detek) during 4 consecutive hours and to bring it back to the clinic or mail it to the laboratory. Endocervical and urine specimens were tested using the Cobas Amplicor CT/NG assay (Roche Diagnostic Systems) according to the manufacturer's instructions, as were specimens collected with the napkin after adequate preparation. If the PCR test result was positive on the endocervical sample or on any two samples, a woman was considered to be infected. PCR testing results on paired samples were identical for 493 (96.6%) of 510 women. According to the definition given above, 58 (11.3%; 95% confidence interval [CI], 8.7 to 14.5%) women were infected with C. trachomatis. The sensitivity and specificity of PCR testing on modified sanitary napkin specimens were, respectively, 93.1% (54 of 58; 95% CI, 83.3 to 98.1%) and 98.9% (447 of 452; 95% CI, 97.4 to 99.6%) compared to 81.0% (47 of 58; 95% CI, 68.6 to 90.1%) and 100% (451 of 451; 95% CI, 99.2 to 100%) for urine specimens. The positive and negative predictive values were, respectively, 91.5% (54 of 59) and 99.1% (447 of 451) for the sanitary napkin specimens compared to 100% (47 of 47) and 97.6% (451 of 462) for urine samples. These results suggest that a modified sanitary napkin represents an effective noninvasive device for self-collection of specimens to detect urogenital C. trachomatis infection.  (+info)

Urinary incontinence in older people in the community: a neglected problem? (2/23)

BACKGROUND: The prevalence and impact of urinary incontinence has been investigated much less in older men than in older women. It is suggested that those who perceive that their daily lives are affected should have priority for services. However, many people do not seek medical help, even though they may be severely affected. AIM: To investigate unmet need in relation to the prevalence and impact on everyday life of urinary incontinence in men and women over the age of 65 years. DESIGN OF STUDY: Cross-sectional survey to measure prevalence of urinary incontinence, the impact on people's lives, use of protection, and health services. SETTING: Stratified random sample of 2000 community-living elderly (equal numbers of men and women, aged 65 to 74 years and over 75 years) in 11 general practices in a British city. RESULTS: The response rate was 79%. The overall prevalence of incontinence in the previous month was 31% for women and 23% for men. Women generally had more severe frequency of incontinence and a greater degree of wetness than men. Protection use was greater in women than in men. Only 40% of men and 45% of women with incontinence had accessed health services. Significant predictors of the use of health services were: incontinence reported as a problem, increased frequency of incontinence, and greater degree of wetness. About one-third of people who leaked with severe frequency or who reported that it was a problem had not accessed NHS services for incontinence. CONCLUSIONS: Urinary incontinence is a common problem for older men and women living in the community and can have a deleterious effect on their lives. There is the opportunity to improve the lives of many older people with urinary incontinence, probably by a combination of increased public, patient, and professional awareness that should lead to earlier presentation and initiation of effective care.  (+info)

Interventions led by nurse continence advisers in the management of urinary incontinence: a randomized controlled trial. (3/23)

BACKGROUND: The short-term efficacy of combined lifestyle and behavioural interventions led by nurses in the management of urinary incontinence has not been rigorously evaluated by randomized controlled trial. We conducted a 6-month randomized controlled trial to determine whether a model of service delivery that included lifestyle and behavioural interventions led by "nurse continence advisers" in collaboration with a physician with expertise in continence management could reduce urinary incontinence and pad use in an outpatient population. We also aimed to evaluate the impact of this approach on subjects' knowledge about incontinence and their quality of life. METHODS: We used advertising in the mainstream media, newsletters to family physicians and community information sessions in 1991 to invite volunteers who were 26 years of age or older and suffered from incontinence to participate in a randomized controlled trial. Men and women who met the eligibility criteria were randomly allocated to receive either counselling from specialized nurses to manage incontinence using behavioural and lifestyle modification sessions every 4 weeks for 25 weeks or usual care. Symptoms of incontinence and the use of incontinence pads were the primary outcome measures. RESULTS: Using sealed envelopes, 421 patients were randomly allocated to the treatment or control groups. On average, patients in the treatment group experienced 2.1 "incontinent events" per 24 hours before treatment and 1.0 incontinent event per 24 hours at the end of the study. Control patients had an average of 2.4 incontinent events per 24 hours before the study and 2.2 incontinent events per 24 hours at the end of the study. The mean decrease in events in the treatment group was 1.2 and in the control group 0.2 (p = 0.001). Pad use declined from a mean of 2.2 per 24 hours before randomization in the treatment group to 1.2 per 24 hours at the end of the study, compared with 2.6 pads per 24 hours in the control group at the start of the study and 2.4 per 24 hours at the end. Pad use per 24 hours decreased on average by 0.9 pads in the treatment group and 0.1 in the control group (p = 0.021). INTERPRETATION: Behavioural and lifestyle counselling provided by specialized nurses with training in managing incontinence reduces incontinent events and incontinence pad use.  (+info)

Extended diaper wearing: effects on continence in and out of the diaper. (4/23)

Diaper use is widespread and possibly even increasing across diverse populations in the United States, ranging from infants to very old adults. We found no reports of an experimental analysis of the effect of wearing diapers on the frequency of urinary accidents and the attainment of continence skills (e.g., urinating in the toilet). In this study, we used a withdrawal design to evaluate the effect of wearing diapers on daily urinary accidents and successful voids for an adult who had been diagnosed with mental retardation. Results indicated that wearing diapers increased the rate of accidents and decreased the rate of successful voids. Clinical implications of these results are discussed.  (+info)

What prevents older people from seeking treatment for urinary incontinence? A qualitative exploration of barriers to the use of community continence services. (5/23)

BACKGROUND: Urinary incontinence is a significant health problem for older people. Many people with incontinence do not seek services. Simple and effective treatments exist in primary care. OBJECTIVES: Our aim was to explore reasons why older people living in the community do not present for help with problems of urinary incontinence and to identify ways in which they may be assisted to access continence services. METHODS: In-depth interviews lasting an average of 1 h were conducted with 20 people aged over 65 years living in the community, purposively selected from a sample of patients who volunteered to be interviewed. RESULTS: Older people described ageing as a natural, degenerative process and had reduced health expectations. Urinary incontinence was commonly viewed as an inevitable aspect of ageing and, as such, something to be accepted and managed independently. Shame and embarrassment combined with generational differences in attitudes to disclosure about personal matters also prevented people from seeking advice. Relatively successful strategies to manage incontinence enabled people to contain their symptoms, although this was at a social, psychological and, in some cases, health cost. Older people in this sample had considerable co-morbidity, in many cases resulting in mobility problems. Despite regular contact with primary care professionals, they had seldom disclosed their urinary incontinence. CONCLUSION: A combination of personal attitudes and practical barriers prevent older people from seeking help for urinary incontinence. It is possible that older people would be more likely to seek help if asked specifically about urinary leakage by primary health care professionals.  (+info)

A cost-effectiveness study of the management of intractable urinary incontinence by urinary catheterisation or incontinence pads. (6/23)

STUDY OBJECTIVE: The aim was to compare the costs and effects of management of intractable urinary incontinence by urinary catheterisation or incontinence pads. DESIGN: This was a prospective, randomised study comparing catheterisation with pads, supplemented by additional data collected from patients with chronic indwelling catheters. Main outcome measures were costs of equipment, nursing time, patient preference, nursing preference, and clinical and bacteriological assessment of urinary infection. SUBJECTS: 78 intractably incontinent elderly female patients were randomly allocated to management by urinary catheter or pads and toileting. Supplementary data on equipment costs and nursing time were collected from 27 patients, of whom 22 were already catheterised at the time of the randomisation and five were catheterised by the nursing staff after the last date for entry into the randomisation. MAIN RESULTS: Of the 38 patients randomised to catheterisation, 14 refused consent so only 24 were catheterised on day 1 of the study. There was a rapid removal of catheters, especially in the first six weeks of the study and only four of the randomised catheter patients completed the full 26 weeks of the study. However, eight of the pads patients were catheterised between the 7th and 22nd week because of deteriorating general condition and all retained their catheters for the remainder of the study period. Of 35 patients who had experienced catheters and pads, 12 expressed a clear preference for catheters, 12 for pads, and 11 were undecided. Nurses were in favour of the use of pads, mainly because of concerns about urinary infection with catheters. Comparing costs for patients managed with catheters (532 patient weeks) or pads (903 patient weeks), catheter patients required less nursing time (15.4 v 29.0 h per patient per week) but equipment costs were higher (19.20-24.65 pounds v 8.79-11.35 pounds per patient per week), mainly because of the cost of catheter care (12.75 pounds per patient per week). Asymptomatic bacteriuria was prevalent in both groups but 73% of catheterised patients received treatment for clinical signs of infection compared with 40% of pads patients. Only 30% of patients who were treated had any generalised symptoms of infection. CONCLUSIONS: Use of catheters reduces nursing time but may increase weekly equipment costs depending on the cost of laundry. Despite the high dropout rate among patients randomised to catheters a minority of patients (12/35) expressed a clear preference for catheters and we believe that more patients with intractable incontinence should be given a trial of catheterisation to assess acceptability. Bacteriuria was prevalent in pads or catheter patients but no major episodes of invasive infection were noted in either group.  (+info)

The "costs" of urinary incontinence for women. (7/23)

OBJECTIVE: To estimate costs of routine care for female urinary incontinence, health-related quality of life, and willingness to pay for incontinence improvement. METHODS: In a cross-sectional study at 5 U.S. sites, 293 incontinent women quantified supplies, laundry, and dry cleaning specifically for incontinence. Costs were calculated by multiplying resources used by national resource costs and presented in 2005 United States dollars (2005). Health-related quality of life was estimated with the Health Utilities Index. Participants estimated willingness to pay for 25-100% improvement in incontinence. Potential predictors of these outcomes were examined using multivariable linear regression. RESULTS: Mean age was 56 +/- 11 years; participants were racially diverse and had a broad range of incontinence severity. Nearly 90% reported incontinence-related costs. Median weekly cost (25%, 75% interquartile range) increased from 0.37 dollars (0, 4 dollars) for slight to 10.98 dollars (4, 21 dollars) for very severe incontinence. Costs increased with incontinence severity (P < .001). Costs were 2.4-fold higher for African American compared with white women (P < .001) and 65% higher for women with urge compared with those having stress incontinence (P < .001). More frequent incontinence was associated with lower Health Utilities Index score (mean 0.90 +/- 0.11 for weekly and 0.81 +/- 0.21 for daily incontinence; P = .02). Women were willing to pay a mean of 70 dollars +/- 64 dollars per month for complete resolution of incontinence, and willingness to pay increased with income and greater expected benefit. CONCLUSION: Women with severe urinary incontinence pay 900 dollars annually for incontinence routine care, and incontinence is associated with a significant decrement in health-related quality of life. Effective incontinence treatment may decrease costs and improve quality of life. LEVEL OF EVIDENCE: III.  (+info)

Quantifying the natural history of post-radical prostatectomy incontinence using objective pad test data. (8/23)

BACKGROUND: Urinary incontinence (UI) following radical prostatectomy is a well-recognized risk of the surgery. In most patients post-operative UI improves over time. To date, there is limited objective, quantitative data on the natural history of the resolution of post-prostatectomy UI. The purpose of this study was to define the natural history of post radical prostatectomy incontinence using an objective quantitative tool, the 1-hour standard pad test. METHODS: 203 consecutive patients underwent radical prostatectomy by a single surgeon between 03/98 & 08/03. A standardized 1-hour pad test was administered at subsequent postoperative clinic visits. The gram weight of urine loss was recorded and subdivided into four groups defined according to the grams of urine loss: minimal (<1 g), mild (>1, <10 g), moderate (10-50 g) and severe (>50 g). Patients were evaluated: at 2 weeks (catheter removal), 6 weeks, 18 weeks, 30 weeks, 42 weeks and 54 weeks. The data set was analyzed for average urine loss as well as grams of urine loss at each time point, the percentage of patients and the distribution of patients in each category. RESULTS: Mean follow up was 118 weeks. The majority of patients experienced incontinence immediately after catheter removal at 2 weeks that gradually improved with time. While continued improvement was noted to 1 year, most patients who achieved continence did so by 18 weeks post-op. CONCLUSION: While the majority of patients experience mild to severe UI immediately following catheter removal, there is a rapid decrease in leaked weight during the first 18 weeks following RRP. Patients continue to improve out to 1 year with greater than 90% having minimal leakage by International Continence Society criteria.  (+info)
