The AUSTRALASIAN ANAESTHESIA 2011 Blue Book has a quote from a doctor, Anne-Marie Welsch, that is the highest figure I have found. She does not source her quote, but Australia is notorious for being a hot bed for JW blood management people and it would not surprise me if the source is the JWpeople involved in Australia's blood management. "It is estimated that approximately 1000 Jehovah’s Witnesses die annually worldwide and as many as 100,000 may have died by abstaining from blood transfusions since the blood ban was introduced in 1945. "
This website has some figures: http://ajwrb.org/
Maternal deaths rates:
Marvin Shilmer posted the following calculation to the Jehovahs-Witness.com discussion forum:
"Assuming an annual birth rate of 20 per 1,000, and based on the Watchtower organization's annual statistics, over the period of 1995 through 2006 there were at least 1,455,000 births among Jehovah's Witnesses. Assuming these women presented themselves as refusing blood, this translates into 1,455 deaths during this period." 6
If all had accepted transfusions when needed, only 21 might have died. The Jehovah's Witness' policy on blood transfusions might thus have caused on the order of 10 preventable deaths a month, 120 a year, within their organization.

Why do the health authorities not raise and publish concrete numbers?
