Incontinence in Older Adults: Going Beyond the Bladder Catherine E. DuBeau, MD Clinical Chief of Geriatric Medicine Professor of Medicine UMass Medical School JG is 76 yo woman who comes in for routine follow up of HTN, hyperlipidemia, osteoporosis, and some mild memory problems (she doesn’t drive but still lives independently). She complains of constipation. When you go to examine her, you notice she is wearing “pull-ups.” This suggests: a. The results of having 6 children b. She is likely developing dementia and leakage is common with that condition c. She didn’t mention any incontinence so she must not find it bothersome d. All of the above e. None of the above What is Incontinence? 82 yo, unpredictable sudden urgency with leakage that wets through to her clothing 76 yo, after surgery for prostate cancer leaks large drops with coughing, golfing 87 yo, with end-stage dementia, bed-bound in a nursing home, with no bladder or bowel control 72 yo, leaks when playing tennis and jogging In a survey of patients with at least one episode of incontinence weekly: – Half never sought care – Only 60% those who sought care recalled receiving any treatment – Of those who did receive treatment, 50% reported moderate to great frustration with ongoing urinary leakage Harris SS et al. J Urol 2007 Incontinence – A classic geriatric condition Severity = Frequency x Amount Large leakage at least weekly Hannestad YS, et al. Norwegian EPINCOT Study. J Clin Epidem 2000;53:1150 The Impact of Incontinence • Psychosocial – – – – Decreased quality of life Worry and coping Depression Nursing home placement • Medical consequences – Falls and fractures – Skin infections – UTIs • Economic costs – $26 billion per year – $3,600 annually per person age 65+ What causes UI? • Inability to store urine at low pressure – Uninhibed bladder contractions – Insufficient urethral closure • Inability to empty bladder in timely and effective manner – Inefficient bladder contraction – Urethral or bladder outlet blockage Physiological changes in the LUT with age • Bladder – decreased contraction strength • Urethra (women) – decreased smooth and striated muscle density, decreased vascular density and flow • Vagina, pelvic floor – no change • Prostate – hyperplasia and hypertrophy These changes alone do not cause UI, but increase the vulnerability to develop UI when other stressors occur “Bladder Symptoms” Bladder Condition Other determinants of continence: Environment Mentation Manual dexterity Medical conditions and medications Mobility Factors that Cause or Worsen UI Comorbid Disease • Diabetes • Congestive heart failure • Degenerative joint disease • Sleep apnea • Severe constipation Neurological / Psychiatric • Stroke • Parkinson’s disease • Dementia (advanced) • Depression (severe) Function and Environment • Impaired cognition • Impaired mobility • Inaccessible toilets • Lack of caregivers Ouslander JG.

Add antimuscarinic constipation Add laxative.... Beginning an Incontinence Assessment In the past 3 months, have you ever leaked urine, even a small amount? Yes Did you leak urine most often when you were: When you were performing some physical activity, such as coughing sneezing; lifting or exercising? When you had the urge or feeling you needed to empty your bladder, and could not get to the bathroom fast enough? About equally as often with physical activity as with a sense of Stress Urge Mixed urgency? Without physical activity or without a sense of urgency? Other Brown JS et al. Ann Intern Med 2006:144: 715 Evaluation for the cause of UI • DIAPPERS mnemonic – – – – – – – – Delirium [Infection] [Atrophic vaginitis] Pharmaceuticals Psychological condition Excess urine output Reduced mobility Stool impaction Now evidence that treatment of these does not decrease UI – Physical exam • Rectal examination for fecal loading or impaction (Grade C) • Functional assessment (mobility, transfers, manual dexterity, ability to successfully toilet) (Grade A) • Screening test for depression (Grade B) • Cognitive assessment (to assist in planning management, Grade C) DuBeau CE et al, Incontinence in Frail Elderly, 4th International Consultation on Incontinence, 2008 Characterize the type of UI – Physical exam – Rectal exam – impaction, prostate nodules (not size) – Pelvic exam – pelvic organ prolapse Urethra Cystocele Rectocele Hymenal ring Split speculum – Cough stress test (full bladder, upright) • Confirm stress symptoms – Post-voiding residual volume – not necessary in initial evaluation Importance of Treatment Goals 82 yo, unpredictable sudden urgency with leakage that wets through to her clothing Decreased costs of pull-ups, go out without worry about visible leakage or smell; occasional urgency tolerable 76 yo, after surgery for prostate cancer leaks large drops with coughing, golfing No leakage 87 yo, with end-stage dementia, bed-bound in a nursing home, with no bladder or bowel control Prevention of skin breakdown, dignity, comfort 72 yo, leaks when playing tennis and jogging Ability to be active without worry; avoid surgery Stepwise UI Treatment Lifestyle Urge Stress Mixed Behavioral Urge Stress Mixed Drugs Urge Mixed Surgery Urge (severe) Stress Mixed Indications for immediate referral • Hematuria • Pelvic pain • Acute onset of UI • Complex neurological disease other than dementia • Pt desires surgery for stress UI • Marked pelvic floor prolapse • Dysuria, pain, frequent small voids (possible interstitial cystitis) Lifestyle Caffeine and diuretic beverages Fluid intake 60% UI reduction (IQR Constipation 30% to 89%) with large Weight loss (16 kg) weight loss via liquid diet Smoking 30% decrease in odds for stress UI with 3.5 kg loss Subak LL et al.
