Urinary incontinence
Island Docs are generalists. We strive to maintain a breadth of knowledge rather than focus on a particular specialty field. In our efforts to provide high quality patient care, we work hard to keep up to date with the latest evidence and guidelines. We are lucky to receive regular visiting specialists, who continue to teach us and support us. In this section, we go back to basics and present approaches to common conditions seen in rural general practice. We’ll also try to include any hot tips and tricks from our visiting specialists.
GP Summary: Urinary Incontinence
FROGS Outreach Teaching 13/03/2018
Urinary incontinence in women is common and likely affects many women in the Torres Strait. It can have a significant impact on quality of life and some women avoid seeking health care due to lack of knowledge, embarrassment or fear. Health practitioners don’t always explore urinary symptoms opportunistically and this session has helped to reinforce the importance of asking and assessing women for urinary symptoms.
