  • Self-Management of Urinary and Fecal Incontinence
    2.3 HOURS CE Continuing Education Self-Management of Urinary and Fecal Incontinence Employing evidence-based strategies can help patients take better control. OVERVIEW: Widely used by patients to control symptoms of chronic conditions such as diabetes, asthma, and arthritis, self-management can also help patients with urinary or fecal incontinence. The authors dis- cuss the principles of self-management, the behaviors and skills self-managing patients need to acquire, and the nurse’s role in reinforcing their use. They then describe strategies that can be incorporated within the framework of self-management to control urinary, fecal, or dual incontinence.

But older women fail to seek medical help for UI because many believe incontinence is a normal part of ageing and are not aware cure is possible. The sensitive but non-life- threatening nature of UI means that women tend to delay seeking help until the condition becomes intolerable. CACTUS-D3 tested an evidence-based continence promotion workshop against a control, health workshop in four different localities, France, UK, Quebec and Western Canada. 909 women aged 65-98 years with untreated UI, were recruited from 377 community groups. 751 participants (83%) completed the 1-year follow-up. Urinary symptom improvement was achieved and maintained from 3-months onwards in the intervention group. In 1-year intent-to-treat analyses, 15% of the intervention arm reported clinically important UI improvement compared to 7% of controls. 35% vs 19% reported any improvement . Compared to controls, the intervention group reported a mean 1.28 point (95% CI 1.15 - 1.41) improvement in incontinence-related quality of life at 1-year.

  • Prevalence of Commonly Prescribed Medications Potentially Contributing to Urinary Symptoms in a Cohort of Older Patients Seeking
    Kashyap et al. BMC Geriatrics 2013, 13:57 http://www.biomedcentral.com/1471-2318/13/57 RESEARCH ARTICLE Open Access Prevalence of commonly prescribed medications potentially contributing to urinary symptoms in a cohort of older patients seeking care for incontinence Mandavi Kashyap1, Le Mai Tu2 and Cara Tannenbaum1* Abstract Background: Several medication classes may contribute to urinary symptoms in older adults. The purpose of this study was to determine the prevalence of use of these medications in a clinical cohort of incontinent patients. Methods: A cross-sectional study was conducted among 390 new patients aged 60 years and older seeking care for incontinence in specialized outpatient geriatric incontinence clinics in Quebec, Canada. The use of oral estrogens, alpha-blocking agents, benzodiazepines, antidepressants, antipsychotics, ACE inhibitors, loop diuretics, NSAIDs, narcotics and calcium channel blockers was recorded from each patient’s medication profile. Lower urinary tract symptoms and the severity of incontinence were measured using standardized questionnaires including the International Consultation on Incontinence Questionnaire. The type of incontinence was determined clinically by a physician specialized in incontinence. Co-morbidities were ascertained by self-report. Logistic regression analyses were used to detect factors associated with medication use, as well as relationships between specific medication classes and the type and severity of urinary symptoms. Results: The prevalence of medications potentially contributing to lower urinary tract symptoms was 60.5%. Calcium channel blockers (21.8%), benzodiazepines (17.4%), other centrally active agents (16.4%), ACE inhibitors (14.4%) and estrogens (12.8%) were most frequently consumed. Only polypharmacy (OR = 4.9, 95% CI = 3.1-7.9), was associated with medication use contributing to incontinence in analyses adjusted for age, sex, and multimorbidity.

Abstract accurate measurement and improvement of population mental health requires the recording of indicators that capture the full spectrum of disease severity. This paper describes four different strategies for measuring the prevalence of depression and anxi- ety in Canada based on data from the 2002 Canadian Community health Survey – mental health and Well-being (Cycle 1.2) and the 2003 Quebec medical services claims database. The use of multiple indicators provides a more comprehensive picture of mental health needs than a single indicator alone. however, the validity of these indicators raises certain challenges and highlights the complexity of obtaining valid and sustainable measurements of mental health problems over time. We include a dis- cussion of problems related to information availability and management. Résumé L’établissement d’indicateurs pour l’ensemble de l’indice de gravité des maladies est essentiel pour obtenir des mesures précises et pour améliorer la santé mentale de la population.
