The purpose of this study was to investigate incidence and treatment of ectopic pregnancy in Norway (1990 to 2001).
Data were compiled from hospital discharges (1990 to 2001) and hospital outpatient care (2000 to 2001) as reported to the National Patient Registry. Selection was based on ICD-9 and ICD-10 codes for ectopic pregnancy (women, 15-44 years old).
The incidence rate decreased from 17.3 to 9.5 per 10 000 women-years and the ratio to live births decreased from 26.4 to 14.9 per 1000 over the study period. Women aged 25-34 had the highest incidence rate of ectopic pregnancy. Measured as ratio per 1000 live births, ectopic pregnancy increased with age. Laparoscopic treatment was much more used, whereas length of hospital stay fell off continuously. The proportion of patients re-admitted was stable throughout the period (5%). In 2000 and 2001, every third patient had at least one outpatient consultation. There were large variations between counties in the proportion of patients treated by laparoscopy and in the prevalence of outpatient care.
The observed decrease of ectopic pregnancy measured as incidence rates and ratio to live births indicates increased fertility. In some counties it might be possible to increase the use of laparoscopy, which might result in shorter hospital stays.
本研究旨在调查挪威（1990年至2001年）异位妊娠的发病率及治疗情况。
数据来自向国家患者登记处报告的医院出院记录（1990年至2001年）和医院门诊护理记录（2000年至2001年）。入选标准基于国际疾病分类第9版（ICD - 9）和第10版（ICD - 10）中异位妊娠的编码（年龄在15 - 44岁的女性）。
在研究期间，发病率从每10000妇女年17.3例降至9.5例，与活产的比例从每1000例中的26.4例降至14.9例。25 - 34岁的女性异位妊娠发病率最高。以每1000例活产的比例衡量，异位妊娠发病率随年龄增长而上升。腹腔镜治疗的使用更为普遍，而住院时间持续缩短。在此期间，再次入院患者的比例保持稳定（5%）。在2000年和2001年，每三名患者中就有一人至少进行过一次门诊咨询。各县在接受腹腔镜治疗的患者比例和门诊护理的普及程度方面存在很大差异。
以发病率和与活产的比例衡量，观察到的异位妊娠减少表明生育能力增强。在一些县，有可能增加腹腔镜的使用，这可能会缩短住院时间。
