Analysis of characteristics and influence factors of diagnostic delay of endometriosis / 中华妇产科杂志

ABSTRACT

Objective To access the influence factors of diagnostic delay of endometriosis. Methods We designed a questionnaire of diagnostic delay of endometriosis. From February 2014 to February 2016,400 patients who had dysmenorrhea and diagnosed with endometriosis by surgery in Peking University Third Hospital were surveyed retrospectively. Time and risk factors of diagnostic delay were analyzed.Results The diagnostic delay of 400 patients was 13.0 years(0.2-43.0 years),78.5%(314/400) patients thought pain was a normal phenomenon and didn′ t see the doctor. Patients who suffered dysmenorrhea at menarche experienced longer diagnostic delay than those who had dysmenorrhea after menarche(18.0 vs 4.5 years;Z=191.800,P<0.01).Patients who suffered aggravating dysmenorrhea experienced shorter delay time than those who suffered stable or relieving dysmenorrhea(11.0 vs 12.5 vs 18.0 years;Z=8.270, P<0.05), with the difference statistically significant, single factor analysis shows. Severe dysmenorrhea, deep infiltration endometriosis(DIE), family history of dysmenorrhea or endometriosis, previous surgical history of endometriosis,high stage,with infertility,adenomyoma or other symptoms,could help to shorten diagnostic delay with no significant difference(P>0.05). By multiple logistic regression analysis,the results shown that whether have dysmenorrhea at menarche and clinical diagnosis time were the independent factors affecting delayed diagnosis(P<0.01).Conclusions Diagnostic delay of endometriosis is common and the mean delay time is 13.0 years mainly due to the unawareness of dysmenorrhea. Dysmenorrhea at menarche,clinical diagnosis time and dysmenorrhea intensity are the factors affecting time of diagnostic delay.
