predictive factors of hysterectomy in the city of ilam: the area under the receiver operating characteristic (roc) curve model approach

Background: hysterectomy pertains tothe removal of the uterus and the cervix without removal of adenexes. hysterectomy is one of the most common surgical procedures and in the united states it ranks as the second common operation after cesarean. the objective of this study is to investigate the related variables involved among women with hysterectomy in the shahid mustafa khomeini hospital inthe city of ilam, iran. methods: a retrospective case-control study was conducted on 150 women including 75 in the control group and 75 as the case group. the cases were women with hysterectomy during 2009-2011, and the control group was randomly selected out of women referred to the hospital in these years and hospitalized due to other causes other than hysterectomy.data were analyzed using spss software, version 17. t-test and chi-square test were used as appropriated.precision the prediction models evaluated using a receiver operating characteristic (roc) curve. results: in this study, of the all operations (2009-2011) performed on women in the shahid mustafa khomeini hospital in ilam, 76 women (3.8%) had undergone hysterectomy.the mean age of women with hysterectomy and the control group were 48.2 and 28.8 respectively. the mean numbers of pregnancies forthe control group as well as women with hysterectomy were 2.18% and 6.33%, respectively. the most common cause of hysterectomy was abnormal uterine bleeding (52%). there was a significant relationship between age and the risk of hysterectomy (p < 0.001). considering the pelvic mass, 4 (5.3 %)of the cases and 33 individuals (44%) who had a history of hysterectomy had such a mass (p < 0.001, or = 13.94). conclusion: as revealed in this study, hysterectomy in most cases is performed aboutthe menopause age when the incidence of abnormal uterine bleeding is relatively common. thus, it might be possible to treat the patient with maintenance therapy in order to reduce the prevalence of hysterectomy.
