Persoonlijk profiel


I am a professor of primary care, focussing on the durable accessibility of primary care. 

My previous works were mainly on urological research, especially the epidemiology of male lower urinary tract symptoms (including nocturia), and prostate cancer screening in general practice. 

I lead the research program 'Pelvic- and abdominal problems', that includes five research themes. Next to this, I have conducted (ongoing) studies on interdisciplinary consultations between GPs and specialists, and I am involved in the Dutch General Practice Research Consortium, as one of the coordinators.


  • Treatment of female stress urinary incontinence: bulking agents and midurethral slings
    In this observational study, two treatments for stress UI are compared on outcomes and patient preferences. This project is initiated and conducted in Isala (Marian Engberts and Hugo van Eijndhoven).

  • Child incontinence
    Mixed-method study, including qualitative approach towards expectations and experiences of children (and their parents) with urinary incontinence as the reason for referral to secondary care at Isala (Zwolle), questionnaire study involving referring GPS, retrospective and prospective database on diagnostic and treatment pathways.

    Funded by Isala Innovation & Science (144K)
    Status: ongoing.

  • Outpatient care for prolaps and urinary incontinence
    Women with prolapse or incontinence, referred to secondary care at Isala are followed for one year. At inclusion, women are asked for their treatment preferences and expectations. Diagnostic and treatment patterns are studied.

    Funded by Isala Innovation & Science (28K).
    Status: data collection completed.

  • URinControl 
    In the URinControl study, an app was developed for women with involuntary loss of urine. In an RCT, the effectiveness and cost-effectiveness were demonstrated compared to standard care. The app treatment turns out to be non-inferior and saves money.
    In 2021 Anne Loohuis obtained her doctorate for her research
