BJOG 2011;118:1484–1490. Objectives Few women with gestational diabetes (GDM) are tested for type 2 diabetes in the postpartum period. Whether women are having physician visits that could be an opportunity to improve testing rates is unknown. This study sought to evaluate population‐level trends in postpartum diabetes testing after GDM, and to evaluate postpartum physician care for these women. Design Population‐based cohort study. Setting Ontario, Canada. Population Women who delivered between 1994 and 2008. Methods Using population‐level healthcare databases, we identified 47 691 women with GDM. They were matched to women without GDM. Main outcome measures An oral glucose tolerance test (OGTT) within 6 months postpartum, the specialty of the physician ordering the test, and ambulatory care visits with physicians from various specialties within 6 months postpartum were recorded. Results Most women with GDM did not receive an OGTT, although testing rates increased slowly over the 14 years of the study, compared with no change in testing for women who had not had GDM. Virtually all women with GDM had postpartum visits with a family physician or obstetrician, but few OGTTs were ordered by physicians from these specialties. Conclusions Despite a slow increase in testing over time and high rates of postpartum visits to family physicians and obstetricians, few women with GDM received the recommended diabetes test. This represents a missed opportunity in a high‐risk population. Interventions to change test ordering that target family physicians and obstetricians are most likely to increase the proportion of women with GDM who receive postpartum diabetes testing.
