Evaluating the Postpartum Maternal Health Clinic: How Patient Characteristics Predict Follow-Up.

Abstract

At Kingston General Hospital, women who have pregnancy-related cardiovascular risk indicators (e.g., preeclampsia, gestational hypertension, gestational diabetes) are offered standardized six-month postpartum follow-up for cardiovascular disease risk screening and counselling. We sought to assess how patient characteristics predict attendance at follow-up. We undertook a chart review of 650 patients who delivered between April 2011 and December 2014 and had preeclampsia, gestational hypertension, or gestational diabetes. Logistic regression was used to analyze the relationship between clinical and demographic variables and attendance at the follow-up clinic. Increasing age (in years) was significantly correlated with attendance at follow-up (adjusted OR [aOR] 1.08, 95% CI 1.04 to 1.12). Women who had preeclampsia were significantly more likely to attend than women who had gestational hypertension or gestational diabetes (aOR 1.54, 95% CI 1.05 to 2.26). Women who were known to be non-smokers or whose smoking status was not recorded were significantly more likely to attend follow-up (aOR 2.47, 95% CI 1.32 to 4.62). There was a trend towards lower follow-up for women from census tracts or subdivisions with a greater proportion of individuals without educational certificate, diploma, or degree, but this was not statistically significant (aOR 0.10, 95% CI 0.01 to 1.22). There is significant selection bias among women who attend follow-up for postpartum cardiovascular disease risk screening and counselling after pregnancies complicated by preeclampsia, gestational hypertension, or gestational diabetes.
