title: Management guidelines for women with normal colposcopy after low grade cervical abnormalities: population study.
abstract: OBJECTIVE
  To develop an evidence based protocol for the follow up of women with low grade cervical abnormalities for whom treatment is not immediately indicated.
  
  
  METHODS
  Population outcome study.
  
  
  METHODS
  Colposcopy clinic of an inner city teaching hospital.
  
  
  METHODS
  566 women with low grade cytological abnormalities who were not treated at a first visit to the colposcopy clinic, followed up for a total of 881 years.
  
  
  METHODS
  Resolution of abnormalities, persistence of disease, and treated disease.
  
  
  RESULTS
  Abnormalities resolved in 306 (54.1%) women, whereas 138 (24.4%) had persistent disease and 122 (21.5%) were subsequently treated. Colposcopic opinion, smear test results, age, smoking history, and number of pregnancies were all significantly related to outcome. Logistic regression analysis produced a model that correctly identified 70% of women whose abnormalities resolved. Only 23 of 295 women (7.8%) with a normal cervix on colposcopy and a smear without dyskaryosis at a first visit were treated by the end of the observation period.
  
  
  CONCLUSIONS
  Women referred with low grade cytological abnormalities who have a normal cervix on colposcopy and a negative or borderline repeat smear test result may be discharged from the colposcopy clinic. We propose a follow up protocol that could safely avoid unnecessary visits to a clinic.
