Abstract
BACKGROUND: As genital chlamydia (Chlamydia trachomatis) notifications have increased in Australia, time trends in hospitalisations for ectopic pregnancy and female infertility between 2001 and 2008 in New South Wales (NSW), Australia, and their relationship to trends in chlamydia notifications in women were assessed. METHODS: Annual rates of chlamydia notification, and hospitalisations for female infertility or ectopic pregnancy in women aged 15-44 years in NSW were calculated using routinely collected data. Chlamydia notifications and hospital separations occurring within each year belonging to the same woman were linked using probabilistic linkage of identifiers so that multiple notifications and admissions for one woman in each calendar year were only counted once. RESULTS: From 2001 to 2008, the annual rate of chlamydia diagnoses in women increased from 157 to 477 per 100000 population (P(trend)<0.001). Over the same period, the annual hospitalisation rate for women with an ectopic pregnancy decreased from 14.3 to 12.6 per 1000 births (P(trend)<0.001). This decrease was mostly in women aged 25-44 years, with no appreciable fall in women aged 15-24 years (P(trend)=0.8). Meanwhile, the hospitalisation rate for women with infertility of female origin did not follow a consistent trend: between 2001 and 2008, it fluctuated between a low of 479 and a high of 554 per 10000 women who were seeking pregnancy. CONCLUSIONS: These trends in ectopic pregnancy and female infertility suggest that the large increase in chlamydia notifications may not reflect hospitalisations for these two proposed chlamydia-related sequelae.

Reporting rates of ectopic pregnancy: are we any closer to achieving consensus?

Abstract
Calculating rates of ectopic pregnancy in a reliable and reproducible way can be challenging. To date, there is no consensus as to which denominators to use but the authors suggest using the total number of deliveries as a benchmark. In many developing countries where ectopic pregnancy is a major cause of maternal morbidity and mortality, standardisation of epidemiological data is arguably even more important. Using the number of deliveries is probably the most pragmatic and reliable way of quoting ectopic pregnancy rates in developing countries, as structures are usually already in place to record births/deliveries. This would ensure greater consistency and allow more meaningful comparisons to be made, both within individual units over time as well as globally. Using additional denominators is more labour intensive and lends itself to inaccuracy but may nevertheless be useful depending on the issues being addressed. Ultimately, the correct denominator(s) to use should be determined by the clinical question(s) of interest. The authors acknowledge that the statistical analysis used in this paper is based on one retrospective study alone and that further work is required in this area before definitive conclusions can be made.

Abstract
During the last three decades, ectopic pregnancy rates have increased considerably in different parts of the world including Australia. Recent reports, however, suggest that the incidence is decreasing or at least stabilising. An analysis of the New South Wales Inpatient Statistics Data collected during the period between 1990 and 1998 has shown a decline in the rate of ectopic pregnancy after 1993. Overall the rate decreased from 17.4 per 1,000 births in 1990-1991 to 16.2 per 1,000 births in 1997-1998. The decline was greater for women aged 35-44 years than for younger women. The findings are consistent with recent studies in other countries, which indicate slowing or the end of the previous upward trend in the incidence of ectopic pregnancy
