title: A follow-up program for women with previous gestational diabetes mellitus.
abstract: OBJECTIVE
  To analyse the patterns of attendance in a gestational diabetes mellitus (GDM) follow-up program for detection of impaired glucose tolerance and diabetes mellitus.
  
  
  METHODS
  Retrospective cohort study using computerised data from the GDM follow-up program.
  
  
  METHODS
  All women with GDM who delivered at the Mercy Hospital for Women in Victoria between 1 January 1981 and 31 December 1995.
  
  
  METHODS
  Enrollment and maintenance in the follow-up program. Predictors of attendance analysed were attendance for the postnatal oral glucose tolerance test (OGTT), severity of GDM, insulin requirement in pregnancy, age at index pregnancy, country of birth, patient booking status and year of index pregnancy.
  
  
  RESULTS
  There were 3524 women with GDM delivered during the study period. Attendance for postnatal OGTT was 71% and increased from 43.7% to 69.5% to 84.4% during the three five-year periods of the study (P < 0.00001). Entry into the follow-up program was 58% (1743 of 2986 eligible). A further 538 women (15.3%) were awaiting the postnatal OGTT or first follow-up OGTT. By December 1995, 45% of women who had entered the program had been lost to follow-up. Enrollment in the follow-up program was significantly predicted by insulin requirement in pregnancy (odds ratio [OR], 2.22; 95% confidence interval [95% CI], 1.57-3.13), attendance for postnatal OGTT (OR, 1.94; 95% CI, 1.64-2.29), private patient status (OR, 1.31; 95% CI, 1.12-1.54), severity of GDM (OR, 1.50; 95% CI, 1.24-1.82) and age 30 years or more (OR, 1.37; 95% CI, 1.17-1.60). Maintenance in the follow-up program was significantly associated with attendance for postnatal OGTT (OR, 2.67; 95% CI, 2.19-3.24), insulin requirement in pregnancy (OR, 2.56; 95% CI, 1.87-3.50), age 30 years or more (OR, 1.59; 95% CI, 1.34-1.88) and severity of GDM (OR, 1.55; 95% CI, 1.28-1.89).
  
  
  CONCLUSIONS
  There are major difficulties with both recruiting women with GDM into a follow-up program and ensuring their continued attendance. However, a postnatal OGTT and consultation is the most important remediable factor for continuation in a follow-up program. The dedication of the follow-up team administrators rather than the clinical variables of the patients was probably the main determinant of compliance with the follow-up program.
