Hello. Hope you're well and looking forward to a bank holiday weekend full of high-profile policy announcements (just kidding - I hope).

You may remember that I wrote briefly about the hospital standardised mortality ratio (HSMR) debate some weeks back.

Today, I caught a very good section of BBC Radio 4's consistently excellent More Or Less, about this issue.

It talks to researchers who contributed to the Mid-Staffordshire Report, and uses it as the launching pad for a consideration of what HSMRs do and don't tell us that is useful.

The report is a thoughtful and very handy summary of the issues. You can listen again to the programme using BBC iPlayer, following this link.
