The Surgical Checklist
Peter Pronovost's five-item central line checklist and the WHO Safe Surgery Checklist — verification protocols that reduced infection rates to zero and surgical mortality by nearly half, without adding new medical knowledge.
In 2001, critical care physician Peter Pronovost distributed a five-item checklist at Johns Hopkins Hospital for inserting central venous catheters: wash hands, drape the patient, clean the skin with chlorhexidine, avoid the femoral site, remove the catheter when no longer needed. Every item was already known to every physician in the ICU. The checklist contained no new medical knowledge. Over fifteen months the infection rate fell from eleven percent to zero, preventing an estimated forty-three infections, eight deaths, and two million dollars in costs. Gawande built The Checklist Manifesto around this finding — not because the items were surprising but because their effect revealed the structural nature of failure in complex systems and pointed toward its remedy.
