“I’m your friend,” Harvard Business School Professor Michael Porter, MBA, PhD, told a sometimes skeptical audience during his keynote address at the ASA’s annual meeting, ANESTHESIOLOGY 2016. “I’m trying to help you see a better way forward, and avoid the bad outcomes that may happen if we don’t transform healthcare.”

Porter is a well-known economist, an expert on business strategy, and the author of the book Redefining Health Care: Creating Value-Based Competition on Results. In his speech to the ASA, he argued the case for redefining health care by making “value for the patient” the unifying purpose, and he urged anesthesiologists to forget pay for volume.

“How should anesthesiologists engage in bundled payments?” Porter asked. “Jump on them!”

Explaining that he has spent the past 15 years immersed in studying health care delivery, Porter said that he looks on health care as one of the world’s “most fundamental and intractable problems.” He asked listeners to think again about anesthesiology practice, and its role and responsibilities in the future of health care.

The best way to avoid being sued for malpractice is to make certain that all your patients are happy and all their outcomes are good.

Reality is seldom so rosy. Patients aren’t necessarily happy even when their clinical outcomes are as good as they can get. In the event of an undesired outcome, an unhappy patient may easily become a litigious one. A 2011 study in the New England Journal of Medicine estimated that 36 percent of physicians in low-risk specialties such as pediatrics, and 88 percent of physicians in high-risk surgical specialties, would face a malpractice claim by the age of 45. Those percentages climb to 75 percent of physicians in low-risk specialties and 99 percent of physicians in high-risk specialties by the age of 65.

Flaws in clinical practice guidelines

Can clinical practice guidelines protect us? We are all beset by the proliferating standards and guidelines of evidence-based medicine. It’s comforting to think that a court may consider adherence to a legitimate clinical practice guideline (CPG) as evidence of reasonable prudence and acceptable practice. At the same time, physicians know that guidelines are imperfect. Many guidelines are debated and revised over time, some are discontinued when they are found to do more harm than good, and some have been found to be contaminated by conflicts of interest.

Some examples:

>  How long should dual anti-platelet therapy be continued after drug-eluting stent placement? Guidelines currently advise dual antiplatelet therapy for six months to a year after stent placement, and aspirin for life. More recently, the Dual Antiplatelet Therapy (DAPT) study suggests that some patients may benefit from extending dual antiplatelet therapy beyond one year in terms of protection against myocardial infarction, but this benefit is accompanied by increased bleeding risk and a possible increase in all-cause mortality. Physicians are advised to “balance risk factors”.

>  Starting in 2001, there was a push toward much tighter control of blood glucose levels in ICU patients. Tight glucose control after cardiac surgery became a quality measure tracked by the Surgical Care Improvement Project (SCIP) and the Joint Commission. The only evidence basis for tight control was a single-center study that associated intensive insulin therapy with improved outcomes including fewer infections, less ventilator time, and a lower incidence of acute renal failure. But the results couldn’t be replicated. In a landmark multicenter report published in 2009, patients receiving intensive insulin therapy with glucose levels kept between 81 and 108 were shown to have more hypoglycemia, higher mortality, and no difference in morbidity or length of stay. Intensive insulin therapy promptly fell out of favor.

>  Many hospitals in the last several years abruptly switched from povidone-iodine antiseptic solution to chlorhexidine-alcohol (ChloraPrep®) for skin preparation before surgery. They did so on the basis of a 2010 study that claimed substantial benefit for ChloraPrep in reducing the risk of surgical site infection (SSI). But in 2014 CareFusion Corp., the manufacturer of ChloraPrep, agreed to pay the government $40 million to resolve Department of Justice (DOJ) allegations that the company paid kickbacks to boost sales of ChloraPrep, and promoted it for uses that aren’t FDA-approved. The DOJ complaint said the company paid $11.6 million in kickbacks to Dr. Charles Denham, who served at the time as co-chair of the Safe Practices Committee at the National Quality Forum and the chair of Leapfrog’s Safe Practices Committee. He championed the use of ChloraPrep without disclosing his relationship with CareFusion. Subsequent studies have not demonstrated the superiority of any commonly used skin preparation agent in reducing the risk of SSI.

Though the evidence may be flawed, evidence-based medicine has shown an alarming tendency to evolve from guidelines into inflexible rules, especially if payment is linked to them. Physicians may come under pressure from regulators and hospital administrators to apply these rules mechanically, with inadequate attention to context or to a patient’s other health issues. As an excellent article in the British Medical Journal last year pointed out dryly, “The patient with a single condition that maps unproblematically to a single evidence-based guideline is becoming a rarity.” A guideline for the management of one risk factor or disease “may cause or exacerbate another—most commonly through the perils of polypharmacy in the older patient.”

“I’m here to say ‘Yes, they can,’ which is different from ‘Yes, they always do,’” says James Moore, MD, President-Elect of the California Society of Anesthesiologists (CSA).

To the contrary, enthusiasm for electronic medical records (EHRs) is part of a “syndrome of inappropriate overconfidence in computing,” argues Christine Doyle, MD, the CSA’s Speaker of the House.

The two physician anesthesiologists (and self-identified “computer geeks”) squared off in a point-counterpoint debate in New Orleans as part of the American Society of Anesthesiologists (ASA) annual meeting, with Dr. Moore defending the benefits of EHRs and Dr. Doyle arguing against them. Dr. Doyle chairs the ASA’s Committee on Electronic Media and Information Technology, while Dr. Moore leads the implementation of the anesthesia information management system (AIMS) at UCLA.

Legibility, accuracy, quality

Dr. Moore defined safety in anesthesia care as “minimizing patient injury resulting from or occurring during anesthesia, and keeping surgeons from harming patients any more than they have to.” He said that computerization contributes to safe anesthesia care by improving legibility, offering clinical decision support with readily available reference information, and providing alerts and reminders.

Computer tracking of the anesthetized patient’s vital signs is more accurate, Dr. Moore said. It prevents the “normalization” of blood pressure that tends to appear on the paper record. Quality reports are easier to generate and outcomes are easier to measure with EHRs in place, he noted. “Postop troponin levels and acute kidney injury are easy to track.”

“Fighting against those who want to change things is a futile strategy,” declared Jason Hwang, MD, MBA, keynote speaker at the opening ceremonies of the American Society of Anesthesiologists’ annual meeting in New Orleans on Saturday, October 11. “You can’t defend a profession by putting up regulatory and payment barriers to stop the barbarians at the gates.”

Dr. Hwang is a co-author of  The Innovator’s Prescription: A Disruptive Solution for Health Care, the winner of the 2010 Book of the Year award from the American College of Healthcare Executives. An expert on the subject of disruptive innovation, Dr. Hwang told the audience of anesthesiologists from more than 90 countries that the Perioperative Surgical Home (PSH) concept offers an integrated solution to healthcare that can help the profession of anesthesiology adapt, survive, and prosper.

He used the example of Apple Inc. to illustrate how a company can thrive while other huge competitors failed because they yielded to “the irresistible temptation to keep doing what they already did best.”

Faster horses, bigger hard drives

If Henry Ford had asked customers what they wanted, Dr. Hwang said, they would have answered “faster horses”. If you asked people what they wanted from their computers 10 years ago, they would have answered bigger hard drives, more memory, and faster processors. Nobody would have said they wanted a phone. But Apple redefined the business with smartphones and tablets that created their own market, and Apple controls the entire integrated product.

Anesthesiology’s chief problem has been complacency with the status quo, Dr. Hwang said. Profitability has been greatest in the operating room, while the areas of preoperative and postoperative care were ripe for encroachment by hospitalists and other practitioners.

Since the death of comedian and talk-show host Joan Rivers, more information has surfaced about the events on the morning of August 28 at Yorkville Endoscopy. But key questions remain unanswered.

News accounts agree that Ms. Rivers sought medical advice because her famous voice was becoming increasingly raspy. This could be caused by a polyp or tumor on the vocal cords, or by acid reflux irritating the throat, among other possible causes.

So Ms. Rivers underwent an endoscopy by Dr. Lawrence B. Cohen, a prominent gastroenterologist, to evaluate her esophagus and stomach for signs of acid reflux. At the same time, a specialist in diseases of the ear, nose, and throat (ENT) reportedly examined her vocal cords (also known as vocal folds).

We don’t know exactly how much or what type of sedation Ms. Rivers’ may have received, though several news sources have reported that she was given propofol, the sedative associated with the death of Michael Jackson. No physician who specializes in anesthesiology has been identified on the team taking care of Ms. Rivers, and we don’t know who was in charge of giving her propofol.

It seems clear that at some point during Ms. Rivers’ endoscopy and vocal cord examination, there was a critical lack of oxygen in her bloodstream.

Was laryngospasm the cause?

Giving sedation for upper endoscopy is tricky, as any anesthesia practitioner will tell you. A large black endoscope takes up space in the mouth and may obstruct breathing. Any sedative will tend to blunt the patient’s normal drive to breathe. But most patients breathe well enough during the procedure, and go home with no complaints other than a mild sore throat.

News reports have speculated that the root cause of Ms. Rivers’ rapid deterioration during the procedure could have been laryngospasm. This term means literally that the larynx, or voice box, goes into spasm, and the vocal cords snap completely shut. No air can enter, and of course the oxygen in the bloodstream is rapidly used up.
