In the EUPHRATES study mentioned below, we tried to get units to tell us how many PPHs they had had in the previous calendar year, but we were unsuccessful. We also asked people about their definition of PPH and severe PPH and there were considerable differences. We didn't have room for that in the main paper and were going to write it in another. The problem is that the survey was in 2003 so the data are now out of date, but it sounds like it might be still worth getting it together.
Given the lack of consensus, there are problems in getting data from routine systems. In England, PPH is included among the complications recorded in Maternity HES and the reported rate is 10.1 per cent for the financial year 2008-09. Before quoting this, read the stuff on data quality, though. Before we did EUPHRATES, I looked at data by unit and the range was something like 3 per cent to 30 per cent, suggesting that wildly different definitions and inclusion criteria were being used.
In Scotland, special audits of severe maternal morbidity were set up but I can't find the link now as the organisation which did them got merged into NHS Quality Improvement Scotland. I am copying this to Jim Chalmers at ISD Scotland, so he can tell us what happened if no one on this list knows.

Hi Mandie
We have been collected data about all PPHs over a year in a London teaching hospital and will soon collect data for the same year from a DGH. Finding reliable stats is tricky as reporting varies hugely, with some areas reporting severe PPH as the need for a 4 or 5 unit transfusion, which probably gives more indication of practice than severity of PPH.
The LEMMoN study in the Netherland and the Euphrates study across Europe reported variance in measurement and treatment between units let alone regions and countries.
There are some papers out of Australia showing a rise in PPH regardless of mode of delivery (Ford et al and Crowther et al) and an increase from 5% to 12% with normal deliveries in one city- although I can't remember which paper this is right now- will check and get back to you
If you find something more concrete do let me know!

Subject: National PPH rates
Hi,
Hoping someone might be able to help me!
Have come across interesting ethnographic data RE midwifery perception of
PPH rates and am trying to test the perception against recorded national
rates.
Not with standing difficulties with definition and EBL etc. etc I am looking for
rough ball park figures for the last 20 yrs. While mortality rates from PPH are
easily available, I am having trouble locating stats on the trends in over all
incident rates.
Any suggestions where a stats illiterate researcher should look?
Thanks
Mandie
PS my data suggests midwives think the rate is increasing. Surprising I think
given the moving gate posts where a more symptomatic approach is applied in
the defining process and where an appreciation that physiological third stage
management is likely to be associated with an increase in initial loss (which,
incidentally, is considered to be normal)
