The Checklist Manifesto: How to Get Things Right

In a small Austrian town, a three-year-old girl fell into an icy fishpond, leading to an incredible, lifesaving ordeal. Her parents found her lifeless after 30 minutes underwater. 

Despite no signs of life, emergency responders and hospital staff worked tirelessly, performing complex procedures like connecting her to a heart-lung bypass machine and later to ECMO—an artificial lung system. Her body temperature was gradually raised, and after hours of relentless efforts, her heart began to beat. Remarkably, she made a full recovery, underscoring the intricacies and challenges of modern medicine.

This story illustrates how saving a life often involves a vast, coordinated effort among medical professionals. Medicine today is a field of extreme complexity, far removed from the simplicity once promised by antibiotics like penicillin. The World Health Organization lists over 13,000 diseases, and clinicians have thousands of drugs and procedures at their disposal, each with unique requirements.

Consider a typical day at a Boston clinic where doctors handle an array of conditions, from appendicitis in a pregnant woman to complex cancer cases. The sheer variety and intricacy of medical issues they manage is staggering. Similarly, intensive care units (ICUs) exemplify this complexity. They provide life support for critically ill patients, requiring meticulous execution of numerous tasks. A study found that ICU patients need an average of 178 individual actions per day, with even a 1% error rate leading to potentially life-threatening mistakes.

Take Anthony DeFilippo, a patient who suffered severe complications post-surgery. His case required multiple lines and tubes, precise medication adjustments, and constant monitoring. Despite meticulous care, he developed infections from his lines, illustrating the delicate balance between harm and healing in ICUs. After weeks of intensive care, he survived, but many do not, highlighting the fragility of critical care.

The medical profession has responded to this complexity by moving from specialization to superspecialization. Today's doctors undergo extensive training, often into their mid-thirties, to become experts in narrow fields. This specialization has dramatically improved surgical outcomes but hasn't eliminated mistakes, with significant complications and deaths still occurring.

So, what happens when even super-specialists fail? The solution is emerging from an unexpected source outside of medicine, suggesting that perhaps, expertise alone isn't enough. This evolving answer could reshape how we approach the complexities of modern healthcare.

Can Super-Specialization in Medicine Overcome its Growing Complexity and Save Lives?

On October 30, 1935, at Wright Air Field, the U.S. Army Air Corps conducted a flight competition for the next-generation long-range bomber. Boeing’s Model 299, dubbed the “flying fortress,” appeared unbeatable, boasting superior speed, range, and bomb capacity. However, during its demonstration, the plane crashed due to "pilot error"—the pilot, Major Ployer P. Hill, had forgotten to release a new locking mechanism. The aircraft was deemed too complex for a single pilot to manage, leading to Boeing nearly facing bankruptcy.

Determined, a group of test pilots introduced a simple yet revolutionary solution: a pilot’s checklist. This checklist included basic tasks like checking brakes and instruments, ensuring all steps were followed. With this tool, pilots successfully flew the Model 299 for 1.8 million miles without incident. Consequently, the Army ordered nearly 13,000 of the aircraft, now known as the B-17, which played a crucial role in World War II.

The concept of checklists has since proven invaluable in various fields. For instance, in medicine, Dr. Peter Pronovost at Johns Hopkins developed a checklist to prevent central line infections in ICUs. The checklist comprised five basic steps: washing hands, cleaning the patient’s skin, applying sterile drapes, wearing protective gear, and placing a sterile dressing. Despite their simplicity, these steps were often skipped. Pronovost's checklist reduced infections dramatically, saving lives and costs.

Expanding the initiative to Michigan’s ICUs, Pronovost’s checklist reduced infection rates by 66% and saved over 1,500 lives within 18 months. This success story was a testament to the power of simple, structured checklists in managing complex tasks and improving outcomes.

Another remarkable example involved a hospital in Klagenfurt, Austria. Dr. Markus Thalmann and his team created a checklist for rescuing hypothermia and suffocation victims. This checklist ensured all necessary personnel and equipment were prepared, leading to the successful revival of a three-year-old girl and several other patients, demonstrating the checklist’s potential in life-or-death situations.

These stories highlight the profound impact of checklists in enhancing performance and safety across various domains, from aviation to healthcare. By systematically addressing human error and memory limitations, checklists have proven to be a powerful tool in managing complexity and ensuring consistent, high-quality outcomes.

From Flying Fortresses to ICUs: The Transformative Power of Checklists

Four generations after aviation introduced checklists, their ability to prevent failures in various fields is becoming evident. They act as cognitive nets, catching mental flaws like lapses in memory, attention, and thoroughness. The question remains, however, in which situations are checklists most effective?

Two professors of complexity science, Brenda Zimmerman and Sholom Glouberman, categorize problems into three types: simple, complicated, and complex. Simple problems, like baking a cake from a mix, have straightforward solutions. Complicated problems, such as sending a rocket to the moon, require specialized expertise and coordination. Complex problems, like raising a child, involve high uncertainty and require adaptability.

In medicine, checklists can prevent simple errors, like forgetting to wear a mask when inserting a central line. However, the field also involves complicated and complex problems which demand nuanced judgment. For example, managing an ICU patient involves coordinating 178 tasks daily—a feat not easily controlled by checklists alone.

Atul Gawande, the author, stumbled upon a clue to managing complexity while walking past a new hospital building under construction. Watching workers balance on girders, he pondered how they ensured the building’s integrity. The construction of a 350,000-square-foot hospital wing with 3,885 tons of steel and 95 miles of electrical wire seemed daunting. Yet, buildings rarely collapse.

To understand, Atul visited Joe Salvia, a structural engineer, who explained that past Master Builders, who managed entire projects solo, have been replaced by specialists working in concert. Construction now relies heavily on checklists to ensure coordination and communication among the various trades.

For example, at the Russia Wharf building site, a project executive managed hundreds of workers and subcontractors using detailed checklists. These lists outlined every task and its sequence, ensuring steps weren't missed. Additionally, a “submittal schedule” checklist mandated communication among experts to address unforeseen issues.

A tour of the construction site revealed how layers of work were meticulously planned and executed—from steel trusses to fireproofing and plumbing. When an unexpected problem arose, like water pooling on upper floors, the team discussed and resolved the issue collaboratively.

In construction, the biggest errors stem from communication failures. The Citicorp building incident exemplifies this. A change from welded to bolted joints, not reviewed with the lead engineer, nearly led to disaster. Only through emergency intervention was catastrophe averted.

Despite occasional lapses, the construction industry’s checklist system has achieved remarkable success. With nearly five million commercial buildings in the U.S., serious failures are rare, demonstrating the efficacy of checklists in managing complexity.

Reflecting on medicine, the challenge is integrating checklists to prevent simple errors while allowing for expert judgment in complicated and complex scenarios. The construction industry’s approach—combining detailed task lists with mandatory communication—offers a compelling model for reducing failures in multifaceted fields like healthcare.

Can the Construction Industry's Success with Checklists Offer a Solution to Complex Problems in Healthcare?

In the complex building industry, the approach of decentralizing power to tackle challenges stood out. Michael O’Sullivan’s construction site exemplified this with two contrasting checklists: one micro-managed the routine tasks, while the other empowered workers to adapt and make decisions in unexpected situations. This philosophy of pushing decision-making to the periphery is essential in complex scenarios, ensuring that experienced individuals on the ground can swiftly respond.

The catastrophic aftermath of Hurricane Katrina in 2005 underscored the pitfalls of centralized control. Despite initial reassurances, New Orleans was overwhelmed as levees failed, and communication broke down. FEMA’s top-down approach led to delays and chaos, whereas Wal-Mart’s decentralized strategy allowed its managers to act decisively. CEO Lee Scott’s directive to his team to "make the best decision" highlighted the importance of local decision-making. Consequently, Wal-Mart provided critical supplies and aid efficiently, contrasting sharply with the federal response.

Wal-Mart’s success during Katrina wasn’t due to the superiority of the private sector but rather the recognition that complex problems require decentralized, adaptable solutions. This approach also underpins successful skyscraper construction, where checklists ensure essential tasks aren’t overlooked, and communication is prioritized.

The necessity of checklists was further illustrated in various fields. For instance, Van Halen’s no-brown-M&M’s clause in their contracts wasn’t a diva demand but a clever test to ensure venues had read their detailed requirements, avoiding potential safety hazards. In a different domain, chef Jody Adams of Rialto restaurant in Boston used checklists to maintain consistency and quality. Her meticulous recipes and pre-service "pow wows" ensured that her staff could deliver exceptional food consistently.

These examples reveal a fundamental truth: in any complex endeavor, whether constructing a skyscraper, managing a disaster response, or running a high-end kitchen, checklists are indispensable. They provide a framework for reliability and adaptability, ensuring that even in the face of unpredictability, tasks are completed correctly, and communication remains robust.

Decentralized Power and Checklists: Unconventional Strategies for Success in Complexity

In late 2006, a British woman from the World Health Organization (WHO) called Atul to tackle a troubling issue: the rising volume of unsafe surgeries worldwide. Despite his initial reluctance, her challenge to his expertise in patient safety convinced him to help organize a meeting. Together, they discovered alarming statistics: by 2004, 230 million major surgeries were being performed annually, with complications ranging from 3 to 17 percent, leading to millions of deaths and disabilities each year.

At the WHO headquarters in Geneva, a diverse group was gathered—surgeons, anesthesiologists, nurses, safety experts, and even patients—to brainstorm solutions. The stories told by attendees painted a grim picture of global surgical practices. A medical officer from Ghana described how untrained doctors performed surgeries due to a brain drain of skilled professionals. A Russian bioengineer spoke about the dangers of poorly maintained surgical equipment. These stories underscored the complexity and variability of surgical challenges worldwide.

Atul recognized the need for a simple, effective, and scalable solution. Inspired by a public health study where soap distribution in Karachi slums dramatically reduced disease, he wondered if a checklist could improve surgical safety. Initial skepticism gave way to optimism as they examined successful examples, such as Columbus Children’s Hospital’s checklist for preventing surgical infections.

A key insight Atul had was that teamwork and communication were crucial. Studies showed that surgical teams often lacked awareness of each other's roles and the patient’s condition. Implementing a checklist improved teamwork and reduced errors. Trials at Toronto, Johns Hopkins, and Kaiser hospitals demonstrated the checklist’s potential to catch errors and enhance team coordination.

At the Geneva meeting, they consolidated various checklists into a single, streamlined version with three pause points: before anesthesia, before incision, and before leaving the operating room. This checklist included essential steps for preventing infections, managing anesthesia, and ensuring clear communication.

Eager to test it, Atul introduced the checklist in his operating room. The initial attempts were rocky; the checklist was too long and unclear. But the concept showed promise. With refinement and practice, Atul believed a surgical checklist could become a powerful tool to reduce complications and save lives globally.

Can a Simple Checklist Revolutionize Surgical Safety and Save Millions of Lives Worldwide?

After a botched attempt at creating a surgery checklist, Atul turned to aviation for answers. He discovered Daniel Boorman from Boeing, an expert who had spent decades perfecting flight checklists. Visiting him at Boeing’s unassuming headquarters, Atul learned about the intricacies of these life-saving tools.

Boorman’s work is grounded in a history of aviation mishaps and near-misses, with checklists evolving from the lessons learned. For example, a 1989 United Airlines flight encountered a catastrophic mid-flight cargo door failure. Boorman explained how proper checklist procedures, like controlled cabin depressurization, can prevent such tragedies.

Pilots trust their checklists because they are trained to do so and because these lists have repeatedly proven their worth. Boorman explained the crucial distinctions between good and bad checklists, emphasizing brevity, precision, and practical design. He stressed the importance of real-world testing, a principle evident in Boeing’s meticulous simulator training.

Atul experienced this firsthand in a 777-200ER simulator, practicing a scenario where a cargo door warning light signals potential failure. Following the checklist steps, Atul managed to stabilize the plane, underscoring the checklist’s role as a tool for experts. 

The story of British Airways Flight 38 reinforced the checklist’s importance. The plane lost power on final approach due to fuel icing, a previously unknown issue. Investigators devised new procedures, which Boorman’s team distilled into a revised checklist. When a similar incident occurred on a Delta flight soon after, the pilots used the checklist to avert disaster, showcasing the system’s effectiveness.

Boorman taught Atul that checklists don’t replace expertise; they enhance it. They are simple tools that save lives by ensuring critical steps aren’t missed, even in the chaos of emergency situations. From aviation to surgery, the power of a well-crafted checklist is undeniable.

From Boeing to the Operating Room: The Undeniable Power of Checklists

Back in Boston, Atul tasked his team with refining their surgical checklist, inspired by aviation, to be clearer and quicker. Instead of a READ-DO format, they opted for a DO-CONFIRM approach, allowing flexibility while ensuring critical steps were checked. In their mock simulations, they encountered initial challenges, like deciding who should initiate the checklist. Drawing from aviation, they chose the circulating nurse to start it, promoting shared responsibility and vigilance.

Every item on the checklist was scrutinized and timed by Atul and his team to keep it under sixty seconds per pause point. Balancing brevity and effectiveness was tough; some items, like blood clot prevention, were contentious. They eventually dropped non-critical steps to maintain usability.

By spring 2007, they had a working checklist. Atul gathered international experts in London, who debated what to include. Items preventing rare but catastrophic errors, like operating on the wrong patient, stayed. They aimed to foster a team conversation, not just record-keeping.

Testing began in diverse global hospitals, from high-tech facilities in the US and UK to resource-limited ones in India and Tanzania. Despite vast differences, the checklist, developed by Atul and his team, aimed to improve care universally. The hospitals had to measure complications and deaths before and after checklist implementation.

Initial data collection showed alarming complication rates, affirming the need for improvement. Atul then implemented the checklist, training staff and addressing logistical issues. Stories soon emerged, like in London, where it prevented a wrong-sized knee prosthesis from being used, converting skeptics into proponents. In India, timing of antibiotic administration was corrected, preventing infections.

The results, published in the New England Journal of Medicine, were staggering. Major complications dropped by 36%, deaths by 47%. The checklist's impact was consistent across all hospitals, rich and poor. Improved communication seemed key, with 78% of staff witnessing error prevention.

Despite some resistance, the overwhelming majority of surgical staff, 93%, wanted the checklist, developed by Atul and his team, used in their own surgeries, underscoring its effectiveness in enhancing patient safety globally.

Can a Simple Checklist Revolutionize Global Surgical Procedures and Save Lives?

In today’s world, even experts can benefit from simple tools like checklists to reduce mistakes. The medical field has seen remarkable success with the WHO safe surgery checklist, which has been adopted by thousands of hospitals worldwide. However, despite its proven effectiveness, many doctors remain resistant to its use, seeing it as an intrusion rather than a helpful tool. This reluctance is not unique to medicine; it’s also seen in other high-stakes fields like finance.

For instance, renowned investors like Mohnish Pabrai and Guy Spier have found that using checklists significantly improves their investment decisions, reducing errors and increasing efficiency. Pabrai, inspired by Warren Buffett’s mental checklist process, created a detailed written checklist to avoid common investment mistakes. Despite its success, many in the finance industry still resist adopting such systematic approaches, preferring to rely on intuition and experience.

A compelling example of the power of checklists comes from aviation. The successful emergency landing of US Airways Flight 1549 in the Hudson River by Captain “Sully” Sullenberger was not just a result of his skill but also the rigorous adherence to checklists and protocols by the entire crew. This incident highlighted how preparation and teamwork, facilitated by checklists, can lead to extraordinary outcomes.

Similarly, in surgery, checklists have proven life-saving. Dr. Atul Gawande recounts a case where a checklist saved a patient’s life during a complex adrenal gland operation. Despite his extensive experience, a checklist ensured that crucial steps were not missed, and the coordinated effort of the surgical team allowed them to manage a life-threatening complication effectively.

These stories underscore the importance of embracing checklists not as a constraint but as a vital tool for enhancing performance and safety in complex tasks. Whether in medicine, finance, or aviation, the disciplined use of checklists can transform outcomes, turning high-risk endeavors into models of efficiency and reliability. It’s time to update our idea of heroism to include the virtues of preparation, teamwork, and discipline.

Embracing Checklists: The Transformative Tool in Medicine, Finance and Aviation

Modern medicine reveals a critical insight: saving lives often demands a highly coordinated effort among specialized medical professionals. The complexity of today's medical field far surpasses past expectations, with countless diseases and procedures requiring precision to avoid life-threatening mistakes. This complexity also extends to intensive care units, where managing numerous daily tasks for critically ill patients is routine but fraught with potential errors.

The increasing specialization in medicine has improved outcomes but hasn't eradicated mistakes. This realization has led to exploring solutions beyond mere expertise. One transformative tool is the checklist, a concept borrowed from aviation, which has proven effective in managing complexity and preventing errors. For instance, the introduction of surgical checklists has significantly reduced complications and deaths worldwide, underscoring their potential in healthcare.

The construction industry exemplifies how detailed checklists ensure safety and coordination among numerous workers and trades, preventing catastrophic failures. Similarly, in disaster response, decentralized decision-making, facilitated by checklists, has shown remarkable efficiency, as evidenced by Wal-Mart's effective response during Hurricane Katrina.

Checklists in various fields, from aviation to finance, have consistently enhanced reliability and safety. They ensure that critical steps aren't overlooked and that teams communicate effectively. In medicine, despite initial resistance, the adoption of checklists has proven life-saving, demonstrating their indispensable role in improving outcomes in complex, high-stakes environments.
