147
What was his summary points?
1. Urinary incontinence is common in older adults & results in impaired quality of life, morbidity, and increased costs
2. Age-related changes & common disorders/impairments increase an older person’s risk of incontinence
3. Evaluation is based on history, physical, and focused testing
4. Treatment is stepwise, starting with remediation of comorbid and lifestyle factors, progressing to behavioral therapy, medications, and, if necessary, surgery
5. Indwelling catheters should be used with caution, only when absolutely necessary
