This secondary analysis report presents the characteristics of a subgroup of 235 women who are overdue in getting Norplant® implants removed after five years, factors related to the risk of nonremoval after five years, and issues related to accessing information about removal of implants. The main source of data for the present study is the “Norplant Implants® Assessment Study: Insertion, Use, and Removal” carried out in Indonesia in April 1996. This study consisted of a representative sample of 2,979 current and former Norplant users who had an insertion from April 1, 1987, to March 31, 1991, five or more years prior to 1996. The selected sample represented 14 provinces, 50 districts, 150 subdistricts, and 300 villages using stratified, multistage probability proportional to size. The secondary analysis used simple cross tabulations of characteristics and the current use status to study the characteristics of the sample women. The relative risk ratio values were calculated to understand factors related to the risk of not getting implants removed after five years.
