Abstract
A data set consisting of 199 immediate postpartum IUD insertions performed at the Xuan Wu Hospital, Beijing, China was analysed in terms of insertion route, category of inserting personnel and device type. IUD expulsion and continuation of use were the outcome events of interest in this study. Based on our findings, the following hypotheses were derived for future confirmative studies: lower expulsion rates and hence, higher continuation rates of immediate postpartum IUD insertions are associated with (1) insertions through the abdominal incision wound for women who had a cesarean delivery as compared to immediate (less than 10 min) vaginal insertions in women with vaginal delivery; (2) obstetrician insertions, as compared to midwife insertions, and (3) use of the Delta T, as compared to that of the Delta Loop. For the derivation of the latter two hypotheses, only the vaginal insertions were studied.
