Understanding clinical outcomes and
evolving quality measurement systems in healthcare
In the healthcare industry, the race is on to collect meaningful data that will reveal to patients, health insurance companies and employers which physicians and hospitals provide the best quality healthcare. Easier said than done.
In the automotive industry the most recognized study of car quality is the JD Powers annual study that reveals customer satisfaction and customer-reported defects per 100 cars. It is important to note, that the JD Powers study on automotive quality does not take into consideration a car manufacturer’s report on how MANY cars they sold. Instead, it is a study of how customers rate their car, if they would buy another one of the same make and model, and how many problems they had in the first year of owning the car.
The problem of measuring the quality of healthcare
Conversely, there are some huge issues when measuring the quality of healthcare. For one, unlike car manufacturing where the car builder starts with a blank slate of metal and new parts that are then assembled, that is NOT the case with healthcare.
People show up to the doctor in wildly different condition. One 65 year old patient with a herniated disc may show up to the surgeon’s office in perfect body weight for their height, who previously ran half marathons, doesn’t smoke and has no lung or high blood pressure issues. A second 65 year old patient may be obese, on high blood pressure medication, a smoker, and unable to climb a flight of stairs without getting winded.
The Pro Publica surgeon scorecards
USA Today reported on July 12, 2015 a massive Pro Publica study that was used to create “surgeon scorecards” for various elective surgeries. This is a great move forward to collect and report data for patients, health insurance companies and employers. The scorecard taps Medicare data collected by the government from previous years to distill a surgeon scorecard that takes into account deaths while in a hospital, complications and readmissions to the hospital within 30 days.
The problem with ANY embryonic reporting system, however, is that it may not fully take into account the condition of the patient at the start of treatment. Also, as one physician critic noted, does a person get readmitted to the hospital because they fall after the surgery; or because they didn’t take their prescribed anti-coagulation medications correctly; or because the surgeon missed a fracture on an X-ray?
The other complicating issue is patient severity at intake. Said another way, what condition are they in when they walk through the door as a new patient?
For example, the Pro Publica scorecards only take into account Medicare data, which by definition are those people over 65, rather than younger patients. Because Medicare is the only payor that requires hospitals to collect and report data, most healthcare outcome studies today are limited to assessing the quality of healthcare provided to patients from 65 years old to 100 or so.
According to the government agency National Institutes on Health, about 35% of adult Americans 20 and older are classified as “obese”.
Weight Facts on Adults over age 20
- More than two-thirds (68.8 percent) of adults are considered to be overweight or obese.
- More than one-third (35.7 percent) of adults are considered to be obese.
- More than 1 in 20 (6.3 percent) have extreme obesity.
- Almost 3 in 4 men (74 percent) are considered to be overweight or obese.
- The prevalence of obesity is similar for both men and women (about 36 percent).
- About 8 percent of women are considered to have extreme obesity.

These statistics on American adults certainly are not great. But, sadly, the statistics get worse for those who are over 65, that is, Medicare-age healthcare consumers.
Dealing with the health of older Americans
There are about 44 million Americans over the age of 65. The percent of these people not already in healthcare institutions, who are in fair or poor health is 23%. About 8% of these people smoke.
As to obesity, the statistics on Medicare-age patients are not great either.
Percent of non-institutionalized Medicare age people who are obese:
- Men age 65-74: 36.4%
- Men age 75 and over: 27.4%
- Women age 65-74: 44.2%
- Women age 75 and over: 29.8%
Percent of non-institutionalized Medicare age people with hypertension (measured high blood pressure and/or taking antihypertensive medication)
- Men age 65-74 years: 61.7%
- Men age 75 and over: 75.1%
- Women age 65-74: 66.7%
- Women age 75 and over: 79.3%

So it is fair to say, at least one in four Medicare-age patients are obese, and more than half are diagnosed to have high blood pressure, perhaps along with other health issues associated with that.
Who is high quality and who is really poor quality?
As a regional referral center for complex spine patients, Ann Arbor Spine Center is referred patients from across the State of Michigan. The Patient Severity Chart below illustrates the facts about the NEW PATIENTS that walk through our front door:
As a regional referral for back and neck pain, Ann Arbor Spine Center receives a far more complex patient base than other clinics. One in three new patients walking in the front door of Ann Arbor Spine Center have had previous back surgery at other clinics. Half of patients have red flag symptoms like radicular pain and numbness into a leg or arm, which implies disc-related problems, rather than simple acute back or neck strain. About 3 of 4 patients had back pain for 4 months or more. This severity of new patients presents a challenge for a spine center.
How does this severity compare to other physicians? Compared to a small practice of a spine surgeon in solo practice, a regional spine center is likely to be referred more complex patients from a wider geographic area.
This can create a conundrum for the spine surgeon when confronted with a Medicare patient who is 70 years old, obese, a failed back surgery patient from another surgeon six months earlier, yet still in extreme pain and begging for relief. The surgeon who is concerned about his reputation on a “surgeon scorecard” may “pass” on this patient even though there is no other specialist willing to accept the patient.
According to the president of the American Academy of Orthopedic Surgeons, (AAOS), within an interview with Medscape Medical News, ProPublica's methodology "looks to be appropriate and fair." However, the AAOS president said he wonders if the adjustments to complication rates are granular enough to account for all patient differences. Physical deformity and prior surgery also factor into complications, he said. "We haven't stratified all orthopedic risks." He is concerned that Medicare claims data provide a limited picture of a patient's clinical status. The inability to fully account for patient differences, he said, could motivate surgeons to turn down complication-prone cases lest they result in poorer numbers on Surgeon Scorecard.
Already, some physicians now decline to accept Medicare cases because of a variety of concerns: the health of the older patient and safety of performing surgery on a 70-year-old patient; Medicare reimbursement is less than other health insurance providers; onerous government reporting requirements; or because of other government restrictions.
Other physicians accept the issues noted above and accept Medicare patients because they believe it is their community responsibility, and they believe they should do their best to help patients who are suffering from back and neck problems. These same patients ask these physicians for help to a return to an active life, and these physicians do their best to provide their medical expertise in that regard.
The challenge lies in not getting blamed for issues that don’t belong to the surgeon who inherits the worst and most challenging cases.
Making sense of the evolving outcome data
In conclusion, we applaud all efforts to channel more information to patients so they can make better decisions.
The fact that the Internet presence at AnnArborSpineCenter.com is perhaps the most educational source for information on back pain in the State of Michigan demonstrates the commitment of Ann Arbor Spine Center to provide helpful information to those with back or neck problems. We have invested heavily to provide the most educational content on the subject of back pain, neck pain, nonsurgical treatment options for spine and the most advanced surgical treatment options. We print and mail out for free more than 5,000 Home Remedy Books for back pain and neck pain each year — as a community service. We believe the best healthcare comes from a well informed healthcare consumer.
We also are extremely attentive to patient satisfaction. In an outcome study conducted in 2014 on our patients by an outside entity that had an RN call a random sample of patients, 97% of Ann Arbor Spine Center patients said they were very or somewhat satisfied with the time spent by the physician and medical explanation provided. Another 94% said they would recommend the clinic to a friend.
We do feel however, that consumers need to understand more about how to understand the evolving clinical outcome data that is published, because in some cases the physician who provides lower quality care may be mistakenly celebrated as the champion, while the physician who provides higher quality care for complex cases is at risk of scoring lower by virtue of the cases they accept.
The blog below is one physician’s perspective on the Surgeon Scorecards, by Dr. Jen Gunter, an MD board-certified in Ob/Gyn and pain management. We feel it is an interesting perspective on the problem created for those expert surgeons who receive the difficult cases created by others in the system or by accepting high risk patients other physicians turn away.
