Outbreak of Clostridium difficile Infection in a Long-Term Care Facility: Association with Gatifloxacin Use

To determine the cause of an increase in the rate of Clostridium difficile-associated diarrhea (CDAD) in a long-term care facility (LTCF), we analyzed CDAD cases among LTCF patients from October 2001 through June 2002. CDAD cases were identified from review of all enzyme immunoassays positive for C. difficile toxin A. The increase coincided with a formulary change from levofloxacin to gatifloxacin. We performed a case-control study in which we randomly selected control subjects from 612 LTCF admissions during this period. Although we examined a variety of risk factors, logistic regression analysis only demonstrated associations between CDAD and use of clindamycin (P=.005) and gatifloxacin, the latter being associated with an increasing risk of CDAD with increasing duration of gatifloxacin therapy (P<.0001). We concluded that an outbreak of CDAD in an LTCF was associated with a formulary change from levofloxacin to gatifloxacin. The rate of CDAD in the LTCF decreased after a change back to levofloxacin.

Nocturia Frequency, Bother, and Quality of Life: How Often Is Too Often? A Population-Based Study in Finland

BACKGROUND Nocturia (ie, waking at night to void) is common and disrupts sleep. Traditionally, one nightly episode has been regarded as clinically meaningless, yet the justification for this belief remains weak. OBJECTIVE To evaluate the association among frequency of nocturia and bother and health-related quality of life (HRQoL). DESIGN, SETTING, AND PARTICIPANTS In 2003-2004, a survey was mailed to a random sample of 6000 subjects aged 18-79 yr who were identified from the Finnish Population Register Centre (response proportion was 62.4%; 53.7% were females). MEASUREMENTS HRQoL and bother from nocturia were examined in relation to self-reported nocturia frequency (using the American Urological Association Symptom Index and the Danish Prostatic Symptom Score). Bother from nocturia was assessed on a four-point scale (none, small, moderate, major). HRQoL was measured with the generic 15D instrument on a 0-1 scale with a minimum clinically important difference of 0.03. RESULTS AND LIMITATIONS Degree of bother increased with nocturia frequency (p<0.01). The most commonly cited degree of bother for those with one, two, and three nightly voids was no bother, small bother, and moderate bother, respectively. The mean age-adjusted 15D score for men (and women) without nocturia was 0.953 (0.950) and 0.925 (0.927) with one void per night, 0.898 (0.890) with two voids per night, and 0.833 (0.840) with three or more voids per night. Statistically significant decreases were found in 15D score and in all 15D dimensions except eating. Although the response rate was high, approximately one third of those contacted did not participate in the study. CONCLUSIONS At least two voids per night is associated with impaired HRQoL. The majority of people report having bother when the number of nocturia episodes is two and moderate or major bother when the number is three or more. One void per night does not identify subjects with interference from nocturia and, thus, is not a suitable criterion for clinically relevant nocturia.

Incontinence in the frail elderly: Report from the 4th international consultation on incontinence†

To summarize current knowledge on the etiology, assessment, and management of urinary incontinence (UI) in frail older persons. “Frail” here indicates a person with a clinical phenotype combining impaired physical activity, mobility, muscle strength, cognition, nutrition, and endurance, associated with being homebound or in care institutions and a high risk of intercurrent disease, disability, and death.

A Systematic Evaluation of Factors Associated With Nocturia—The Population-based FINNO Study

In a case-control study with prevalence sampling, the authors explored the correlates for nocturia and their population-level impact. In 2003–2004, questionnaires were mailed to 6,000 subjects (aged 18–79 years) randomly identified from the Finnish Population Register (62.4% participated; 53.7% were female). Questionnaires contained items on medical conditions, medications, lifestyle, sociodemographic and reproductive factors, urinary symptoms, and snoring. Nocturia was defined as ≥2 voids/night. In age-adjusted analyses, factors associated with nocturia were entered into a multivariate model. Backward elimination was used to select variables for the final model, with adjustment for confounding. Although numerous correlates were identified, none affected ≥50% of nocturia cases of both sexes. The factors with the greatest impact at the population level were (urinary) urgency (attributable number/1,000 subjects (AN) = 24), benign prostatic hyperplasia (AN = 19), and snoring (AN = 16) for men and overweight and obesity (AN = 40), urgency (AN = 24), and snoring (AN = 17) for women. Moreover, correlates included prostate cancer and antidepressant use for men, coronary artery disease and diabetes for women, and restless legs syndrome and obesity for both sexes. Although several correlates were identified, none accounted for a substantial proportion of the population burden, highlighting the multifactorial etiology of nocturia.

Behavioral Therapy With or Without Biofeedback and Pelvic Floor Electrical Stimulation for Persistent Postprostatectomy Incontinence: A Randomized Controlled Trial

CONTEXT Although behavioral therapy has been shown to improve postoperative recovery of continence, there have been no controlled trials of behavioral therapy for postprostatectomy incontinence persisting more than 1 year. OBJECTIVE To evaluate the effectiveness of behavioral therapy for reducing persistent postprostatectomy incontinence and to determine whether the technologies of biofeedback and pelvic floor electrical stimulation enhance the effectiveness of behavioral therapy. DESIGN, SETTING, AND PARTICIPANTS A prospective randomized controlled trial involving 208 community-dwelling men aged 51 through 84 years with incontinence persisting 1 to 17 years after radical prostatectomy was conducted at a university and 2 Veterans Affairs continence clinics (2003-2008) and included a 1-year follow-up after active treatment. Twenty-four percent of the men were African American; 75%, white. INTERVENTIONS After stratification by type and frequency of incontinence, participants were randomized to 1 of 3 groups: 8 weeks of behavioral therapy (pelvic floor muscle training and bladder control strategies); behavioral therapy plus in-office, dual-channel electromyograph biofeedback and daily home pelvic floor electrical stimulation at 20 Hz, current up to 100 mA (behavior plus); or delayed treatment, which served as the control group. MAIN OUTCOME MEASURE Percentage reduction in mean number of incontinence episodes after 8 weeks of treatment as documented in 7-day bladder diaries. RESULTS Mean incontinence episodes decreased from 28 to 13 per week (55% reduction; 95% confidence interval [CI], 44%-66%) after behavioral therapy and from 26 to 12 (51% reduction; 95% CI, 37%-65%) after behavior plus therapy. Both reductions were significantly greater than the reduction from 25 to 21 (24% reduction; 95% CI, 10%-39%) observed among controls (P = .001 for both treatment groups). However, there was no significant difference in incontinence reduction between the treatment groups (P = .69). Improvements were durable to 12 months in the active treatment groups: 50% reduction (95% CI, 39.8%-61.1%; 13.5 episodes per week) in the behavioral group and 59% reduction (95% CI, 45.0%-73.1%; 9.1 episodes per week) in the behavior plus group (P = .32). CONCLUSIONS Among patients with postprostatectomy incontinence for at least 1 year, 8 weeks of behavioral therapy, compared with a delayed-treatment control, resulted in fewer incontinence episodes. The addition of biofeedback and pelvic floor electrical stimulation did not result in greater effectiveness. TRIAL REGISTRATION clinicaltrials.gov Identifier: NCT00212264.

Effect of fesoterodine in vulnerable elderly subjects with urgency incontinence: A double-blind, placebo controlled trial

PURPOSE We evaluated the efficacy and safety of flexible dose fesoterodine in medically complex vulnerable elderly subjects with urgency urinary incontinence. MATERIALS AND METHODS In this 12-week, randomized, double-blind, flexible dose, placebo controlled trial, subjects were community dwelling men and women 65 years old or older. Subjects had scores of 3 or more on the VES-13 (Vulnerable Elders Survey) and 20 or more on the MMSE (Mini-Mental State Examination), and 2 to 15 urgency urinary incontinence episodes and 8 or more micturitions per 24 hours on 3-day baseline diaries. Subjects randomized to fesoterodine received 4 mg once daily for 4 weeks and could then increase to 8 mg based on discussion with the investigator. Subjects receiving 8 mg could decrease the dose to 4 mg at any time (sham escalation and de-escalation for placebo). The primary outcome measure was change in daily urgency urinary incontinence episodes. Secondary outcomes included changes in other diary variables and patient reported quality of life measures. Safety evaluations included self-reported symptoms and post-void residual volume. RESULTS A total of 562 patients were randomized (mean age 75 years, 50.4% age 75 years or greater). Subjects had high rates of comorbidities, polypharmacy and functional impairment. At week 12 the fesoterodine group had significantly greater improvements in urgency urinary incontinence episodes per 24 hours (-2.84 vs -2.20, p = 0.002) and most other diary variables and quality of life, as well as a higher diary dry rate (50.8% vs 36.0%, p = 0.002). Adverse effects were generally similar to those of younger populations including risk of urinary retention. CONCLUSIONS To our knowledge this is the first antimuscarinic study in a community based, significantly older, medically complex elderly population with urgency urinary incontinence. Flexible dose fesoterodine significantly improved urgency urinary incontinence episodes and other outcomes vs placebo, and was generally well tolerated.
