Joanie Ching, RN MN, Administrative Director of Quality and Safety, blogs about how Virginia Mason Hospital in Seattle is abandoning batch administration of medications to improve patient safety. By going to just-in-time medication administration, nursing workload has been leveled, medication errors have been reduced, and nurses are better able to respond to patient needs.
Editor's note: Workload leveling and smaller batch size, like many other "Lean tools", are industrial engineering concepts that have been well understood for many decades. It appears that a Lean approach has helped Virginia Mason to discover the benefits in this novel.
There are two keys to successful cost-cutting in healthcare: the first - necessary but not sufficient - is to apply proven tools and tactics from industrial engineering, lean, Six Sigma, and business process reengineering; the second is to align the initiative with the organization's mission and culture and engage clinical and administrative staff across the organization to collaborate in the process.
