“…Outside of health care, most studies of organization-level learning from failure look at whether organizations change their behavior in response to failure and the dependent variables are always failure/accident rates or costs (e.g., annual number of automotive recalls [Haunschild and Rhee 2004], bank closure rates [Kim and Miner 2007], airline accident/incident rates [Haunschild and Sullivan 2002], and rail accident costs per operating mile [Baum and Dahlin 2007]). In health care, failure events are not as easily defined and measured (Sutcliffe 2004;Ginsburg et al 2005;Pronovost, Miller, and Wachter 2006) because they are underreported (Lawton and Parker 2002;Greenberg 2009), have relatively low base rates (Rivard, Rosen, and Carroll 2006), and are easily confounded. This makes it useful to focus on more upstream learning processes as we try to measure learning from PS failure events.…”
