Rate of preventable mortality in hospitalized patients: a systematic review and meta-analysis

our estimates equate to approximately 22,165 preventable deaths annually and up to 7150 preventable deaths among patients with greater than 3 months life expectancy.

Pooled eight studies in which physicians reviewed 12,503 consecutive or randomly selected adult hospital deaths. The pooled rate of preventable death was 3.1 percent (95% CI 2.2–4.1), corresponding to about 22,165 US deaths a year, and about 7,150 among patients expected to live more than three months. All pooled studies came from Canada and Europe. The authors note that hospital mortality rates are used for quality measures and reimbursement, and call for a direct US study of preventable hospital deaths.

Finding MED-9.1
Peer-reviewed Published estimates of US deaths caused by medical care range from about 22,000 to about 251,000 a year. The range comes from what each study counts.
Finding MED-9.4
Open question No direct, contemporary study measures how many US hospital deaths are preventable. Every national figure is an extrapolation from small, old or foreign samples.
