Back Pain: Opinion vs. Evidence

I Googled back pain and got 649,000,000 hits. I am sure that the opinions of all those who posted their successful approaches were in there.

Overall I would say the consensus, based on cost and outcomes analysis, is that we do too much treatment of low back pain. Back pain is a symptom that may be caused by a variety of factors.

Deconditioning, muscles, tendons, operable lesions of the skeleton and neuraxis, are all possible causes. It is important to recognize that all the clinicians who posted their very different theoretical models and treatment approaches, believed they were achieving success with a majority of their patients.  How could this be true unless each clinician was treating a unique subgroup of back pain patients?  A recent article (http://bit.ly/1fjuCUT) demonstrated that pain clinicians publishing their outcomes reported an approximately 300% greater success rate than non-pain clinicians reporting on the outcomes of the same procedures.  We are invested in believing that what we do works.

I try to consult the Cochrane Library of Systematic Reviews (www.thecochranelibrary.com) to get a sense of the validity of various approaches for the treatment of back pain. The literature on prolotherapy, trigger point injections, nerve blocks and surgery for chronic low back pain uniformly is found to be inadequate to make a case for the routine use of these approaches.

We need randomized controlled studies that report on function as well as pain intensity and with adequately long follow up data to improve our ability to know what works and for whom.

One reason for the closing of many centers was the pull back by insurance carriers for payments for non-interventional pain treatment services. Doing a procedure seemed to be considered more valid and worthy of payment than a non-invasive service even if it was effective in reducing pain, improving function and lowering future cost of care. Today some of the best pain centers cannot survive by depending on insurance payments and are forced to charge their patients large out of pocket sums in order to remain in operation. Some of these insurance carriers that will not pay for comprehensive pain centers will routinely pay for procedures of questionable effectiveness. Although the number of CARF approved pain centers in the US halved, the number of outpatient pain centers mushroomed. The services provided however focused on two areas:

  1. Medication management
  2. Nerve blocks and other invasive procedures.

Some patients could be helped with one or both of these approaches, but many patients in need of physical therapy and psychological services that had been integrated in a comprehensive treatment plan, would no longer receive optimal treatment. Reimbursement would be the driver of care rather than the needs of the patient. Centers could not stay in business and provide care that insurance companies would not cover. The shift toward procedures became an accepted standard of care and new organizations of pain physicians were formed whose membership focused predominantly on invasive procedures.

The emphasis on medication management was in part fueled by the belief that most patients with persistent pain could be treated successfully and safely with strong pain medications, such as opioids like morphine and oxycodone. We have a better understanding now of problems encountered when we freely offered potent pain medications to too many patients. Strong pain medications not only treat pain but also affect mood. Many patients with or without pain have anxiety and/or depression. Pain medications can provide emotional relief and patients would take them consciously or inadvertently for psychological rather than pain relief. Prescribed pain medication have become more popular than street drugs such as heroin for people who were drug abusers and some patients feigned pain and sold the prescribed pills for a handsome profit.

The cost of services for the treatment of back and neck pain, now with many less comprehensive multi-disciplinary centers, has nonetheless continued to rise at an alarming rate. Next time let’s look at the phenomenon of unintended consequences.

John Bonica, M.D. a world renowned anesthesiologist at the University of Washington in Seattle was the individual most responsible for the creation of a new specialty, Pain Medicine. In 1977 The American Pain Society was founded and became the United States national chapter in the International Association for the Study of Pain. Complicated difficult to treat pain patients were usually not successfully treated by a physician representing one medical discipline and thus the multi-disciplinary pain treatment model was created.

Clinicians observed that patients with persistent pain had misconceptions about their condition that inhibited their ability to recover. Patient would frequently say “ if I have pain it means I am harming myself “ resulting in the avoidance of activities that produce discomfort and eventually eliminating many important activities in their life with resulting deconditioning, depression, drug use, dollars spent, and ultimately disability. Pain becomes the focus of life and the more it is pondered the worse it feels. Multi-disciplinary teams composed of a pain management physician, psychiatrist, psychologist, social worker, occupational therapist, physical therapist and pain team nurses were created to address all of the factors associated with perpetuating the patient’s inability to function. Multidisciplinary pain centers provided weeks of intensive full day treatment programs with remarkable success in restoring function to patients disabled with persistent pain.

There is an organization called Cochrane Collaborations that reviews commonly provided treatments for various medical conditions to determine if the treatment is effective, ineffective or undetermined. Almost all of the treatments for chronic back pain have been found to be neither ineffective or effective, meaning the evidence is inconclusive and more and better studies are needed- but multi-disciplinary pain centers have consistently been found to be effective for the treatment of chronic back pain. In the early 1990s there were more than a hundred pain centers certified by the Commission on Accreditation of Rehabilitation Facilities and despite their success, close to half of them are no longer operating. “So what’s up with that?”

A number of my patients who have been struggling with pain management for more than a year may report that although their pain began in one specific spot, over time, it began to spread. Sometimes, over time, neck pain would involve the lower back pain as well. Many of these patients were thought to possibly have fibromyalgia syndrome and were given anticonvulsant or serotonin-norepinephrine reuptake inhibitors (SNRIs). The spread of pain may be from central sensitization (CS) (http://bit.ly/1aVsdg0, http://bit.ly/1bHgSDU). With some of these patients when the worst pain was treated and resolved from one area it could appear in another and muscles not recognized on the initial examination would now be found to be causing discomfort. This could be a function of diffuse noxious inhibitory control (DNIC) http://bit.ly/14Ac4GL,

These confounding problems appear to represent two opposing and confusing phenomenon: CS and DNIC [currently referred to as conditioned pain modulation (CPM)] (http://bit.ly/1aVuish). Do these issues enter into your evaluation and treatment protocols?

The study published in JAMA today demonstrated that from 1999-2010 in 3 key areas, guidelines for the treatment of back pain are being ignored:

  1. Use of recommended NSAIDs and APAP as first line drugs decreased by ~35% whilst not recommended opioid use increased by ~50%.
  2. Not recommended referral from PCPs to specialists for back pain increased by ~106%.
  3. Not recommended use of imaging increased ~50% for MRI and CT and for x-ray remained the same.

Is this a problem? If so, how should it be addressed?

Spine surgery and exercise

I was interviewed, on Doctor Radio on Sirius XM. One of the callers told us that after she had spine fusion her pain was eliminated but if she didn’t do exercises at least every other day her muscles above and below the surgical site would tighten up and  pain would begin to return. Even when surgery is indicated for back pain, proper conditioning of the postural muscles is still important.

If she didn’t have a good physical therapist and she wasn’t motivated to doing her exercises her surgery might have been considered a failure, another Failed Back Syndrome. Too often the need to address muscle health is overlooked in the treatment of persistent pain problems. As I emphasize in End Back Pain Forever, exercise and physical conditioning should be taught in grade school and encouraged throughout our life.

Many Back Surgeries Unnecessary

In the United States we are faced with the highest per capita health costs in the world. One would think that massive expenditures could provide the best care and treatment outcomes, but this is not the case. In many aspects the US is worse or no better than countries spending 50% of what we do on health care. One reason is that we often inappropriately provide costly evaluation and treatment interventions. We provide surgery too frequently on conditions that could be treated more cost-effectively. Having a step- care model (using the least invasive and potentially harmful, and most cost-effective approaches first) for various conditions would offer models of care for the majority of problems whilst still allowing for modifications in unusual circumstances. —Dr. Norman Marcus

 

By Ryan Sabalow

Some doctors estimate the national rates of unnecessary hysterectomies and back surgeries are even higher than the 25 percent cited by state health officials questioning the Redding area’s high rates of the procedures.

Dr. Ernst Bartsich, a clinical associate professor of obstetrics and gynecology at Weill Cornell Medical College in Manhattan, N.Y., said as many as one in three women in the U.S. has had her uterus removed by the time she’s 60. That number increases to one in two by 65.

Bartsich, an outspoken critic of what he calls the overuse of hysterectomies, said he believes that 85 percent of such procedures could have been avoided through less invasive methods, such as removing painful fibroid tumors from the uterine wall or through medication.

How can we know what back pain treatments make sense?

If the cost of health care is to be reduced in the US, new methods should be established to pay clinicians, pharmaceutical companies and device manufacturers. If graduating medical students are so laden with debt that paying it off is more important than the possibility of ongoing study and academic pursuit, we must lower the cost to the student of medical education. If the cost of drug development is so high that huge prices must be charged for pills, we must find ways to reduce the cost of development of new pharmaceuticals. These fundamental issues in health care have an impact on the standard of care of back pain in the USA. Read the rest of this entry

Bedside Manner and the power of suggestion in back pain

Prior to drawing blood, saying a word to patients that suggested pain increased the likelihood of them experiencing pain. You might think of this study as just another example of the importance of “Bedside manner”- the awareness of the importance of the behavior and speech of the physician or other care-takers, on the feeling of well-being of the patient. Eugene Bauer, M.D., a Viennese physician, said in 1931: “A word in the mouth of a physician is as important as the scalpel in the hands of a surgeon”. Words can cut, soothe, and rattle. How you are approached by a doctor is determined not only by their personality but also by the beliefs concerning your problem.

Obesity, poverty, and community influence- back pain

Obesity is more prevalent in neighborhoods with a high incidence of poverty. A study in the New England Journal of Medicine showed that encouraging families to relocate to higher income neighborhoods could lower the rate of obesity and signs of diabetes. This finding may lead to a better understanding of how we can combat the obesity epidemic. Read the rest of this entry

In the last part of Chapter 1 from End Back Pain Forever, we turn to the story of “Stephanie”. Please review this blog for the complete chapters 1 and 2 from my book.

“Doctor, My Back is Killing Me!”, Part 3

 

Take the case of a patient whom I shall call Stephanie. She is a married attorney who in 2004 began to experience stiffness whenever she she got up out of a chair. She also had problems straightening up if she bent over. This was bothersome, but it was nothing compared to her first attack of spasms in her low back, on the right side. The spasms were incapacitating. She couldn’t walk and had to lie in bed for four days, taking painkillers and muscle relaxants. When the spasms broke, she still felt an inkling of discomfort that would frequently and unexpectedly morph into repeat episodes of painful spasms.

Here is Part 2 of Chapter 1 from my book, End Back Pain Forever.  Click here for Part 1.

Chapter 1

“Doctor, My Back is Killing Me!”, Part 2

“I can put you on strong medication to dull the pain,” says the doctor. “It may be that your spine is the problem.”

“Does that mean surgery?”

“It could. Surgeons do a million spinal operations a year.”

Surgery on your spine is the last thing you want to do, but your back pain is horrendous. And, of course, you want to get better. So you say, “Can’t we do an MRI or a CT scan to see if there’s anything wrong with the spine?” MRI, or Magnetic Resonance Imaging, is a picture generated by magnetic fields, while a CT (computed tomography) scan is a picture generated by X-rays.

When you are shown the test results, the doctor points out that the images of your spine show that you have, say, a herniated disc (in which the cushion between two bony vertebrae is either protruding or has ruptured) or spinal stenosis (narrowing of the spinal column that houses your spinal cord), or some other spinal anomaly–and that, apparently, is the cause of your pain.

But if it were true that the abnormality on the MRI or CT scan was indeed the cause of your pain, I wouldn’t have written this book–because almost no one has a “normal” MRI or CT scan of the lower spine, and what is read as abnormal is frequently not the cause of your pain.

Where to begin? In the first two chapters of my book I explore a variety of issues related to the difficulties in evaluating and treating patients with back pain. I am posting these chapters as a means to share my perspective which developed over more than 40 years as a pain medicine physician in the US and the UK. I wrote End Back Pain Forever to open up a discussion on back pain and provide insights on effective treatments.

 

Chapter 1

“Doctor, My Back is Killing Me!”

You felt a twitch in your low back, then a heaviness and a sudden stab of pain. It struck without warning — when you were crossing the street, stacking the dishwasher, jogging, whacking a golf ball, lifting a baby, swatting a fly, carrying groceries, bending over, getting out of a car, or just turning on a faucet.

Now you’re afraid to move. You’re locked in place. You feel a belt of pain pulsing across your back from hip to hip. You wonder, what’s happening? What did I do to get this? You feel as though you’re cut in half as the pain seems to separate you from your legs. Will the pain go away? Will it stay? Gingerly you start to move, but the pain only strikes harder. No, it’s not going away, not at all. And if — this is a big “if” — the pain does not ease off in a few days or go away in a couple of weeks, without proper treatment it is certain to return because your back is a target waiting to get hit again.

A discussion about back pain

Back PainWhere to begin? In the first two chapters of my book, End Back Pain Forever,  I explore a variety of issues related to the difficulties in evaluating and treating patients with back pain. I am posting these chapters as a means to share my perspective which developed over more than 40 years as a pain medicine physician in the US and the UK. I encourage the members of my LinkedIn Group, Let’s Talk About Pain to agree, disagree, or share your own experience as a patient, family member of a patient, or clinician.

_______________

The cost of evaluating and treating lower back pain and neck pain is rising. From 1997-2005 it went up from $54 to $86 billion/year. Unfortunately, advances in spine surgery techniques, nerve blocks, and pain medication have not translated into more successful treatment – from 1997-2005, 25% more patients reported difficulties functioning because of neck pain or back pain.

Although 70-80% of back pain is diagnosed as non-specific lower back pain, referring to sprains and strains of muscles, ligaments and tendons, the current guidelines do not mention muscle as a possible source of persistent back pain. This leads to an overemphasis on the spine and the nerves leaving the spine.

We need a treatment model (step-care) that addresses the most common reason for back pain first. Protocols that provide soft tissue treatments that are least costly with minimal chance of harm, should produce better, more cost-effective outcomes.

Spending more money to do the same kinds of treatment is not working. This discussion group will explore possible reasons for sub-optimal pain treatment outcomes. How can we change the way we evaluate and treat persistent pain to improve our results and lower the costs of care?

A search for back pain on the internet finds almost 600 million sites. With so many different ideas on how to address this problem, we will attempt to narrow the discussion to concepts that have been studied and published in scientific journals. One obvious issue is the absence of a muscle evaluation and treatment protocol.

Epidural Steroids- Are they worth the downside risk?

The tragic occurrence of meningitis, stroke and death following use of infected steroids used for spine injections should make us more aware that this very common treatment for back pain may not be worth the risks. The use of epidural steroid injections (ESIs) to shrink an inflamed nerve thought to be causing back pain has not been shown to consistently reduce pain and even when it does the benefit is frequently short-lived. Aside from infection, other rare but serious side effects include bleeding that can cause  nerve damage with possble weakness and paralysis, and additional pain. Steroids themselves have been the cause of bone  (aseptic necrosis) and tendon  damage.

Multiple medical professional organizations have suggested that ESIs should not be used for long standing back or neck pain or for pain in the back or neck that does not radiate to the arms or legs. Despite the evidence that even when ESIs reduce or eliminate pain, at best they are useful for 3 months or less. Other countries i.e. Denmark, rarely use ESIs. 

As long as a thorough physical examination does not take place with all patients complaining of back or neck pain, with the purpose of determining if muscles are a source of pain, we will continue to rely on imaging studies that lead us to mistakenly believe that all back pain comes from the spine and the nerves leaving the spine. Continuing to provide unnecessary and ineffective treatments not only squanders our limited resources but could cause irreparable harm.

You Are Not Alone: The Back Pain Epidemic (Part 5)

     Dr. Kraus and I met a week later at Lenox Hill. I had chosen a patient whom I shall call Beth. She was a forty-five year-old woman so defeated by pain after three unsuccessful spinal operations that she could no longer hold a job. Her life had revolved around her work, which was at the core of her sense of self. She was devastated. No one had found a truly successful treatment for her, and I did not believe that anyone could. She was on high doses of morphine, 60 milligrams orally five to six times a day, to relieve her pain.

After reviewing her case history, Dr. Kraus gave her a comprehensive and thoughtful mental and physical examination. Starting with her neck, he used his fingertips to palpate her muscles to distinguish between those that were supple and pain free and those that were stiff and painful. He found five pairs of painful muscles on both sides of the lower back, buttocks, and thighs.  “If these muscles are treated properly,” he told me, “it should reduce or eliminate her pain.” Read the rest of this entry

End Back Pain Forever: Chapter 2, part 4 #endbackpain

This excerpt from my book End Back Pain Forever,  is about my mentor and friend, Dr. Hans Kraus. He changed the way I viewed pain and the treatment of pain, and enhanced my life and ultimately my patients’ lives for the better.

Chapter 2

You Are Not Alone: The Back Pain Epidemic (Part 4)

     Then, in 1993, I met Dr. Hans Kraus. He was to transform my life and the life of my patients. He was eighty-five years old and had just retired from his practice as a specialist in physical medicine and rehabilitation. He had also given up mountaineering and rock climbing. In all those pursuits, he had won international acclaim. Originally trained as an orthopedic surgeon at the University of Vienna, Dr. Kraus was well known for having successfully treated President John F. Kennedy’s back after all prior treatments had failed. Yet his nonsurgical approach to treating patients with muscle pain, especially low back pain, was not accepted by other doctors, including some of the very doctors who referred their own patients to him for what proved to be successful treatment.

For example, one prominent orthopedic surgeon at the Columbia University School of Medicine, Dr. Frank Stinchfield, who routinely sent many of his back pain patients to Dr. Kraus, underwent spinal surgery rather than consult him for his own back pain after a herniated disk was diagnosed. The surgery failed, and Dr. Stinchfield was never able to work again because of unrelenting pain.

Another disappointing example was that of Dr. Jonas Salk, best known for developing the first safe and effective polio vaccine. Dr. Salk did consult Dr. Kraus for back pain, and the treatment was successful. It eliminated Dr. Salk’s pain and allowed him to avoid surgery. Yet when Dr. Kraus needed Dr. Salk’s help to obtain research support, the famed medical researcher declined. He said that muscle pain didn’t have a “scientific foundation.” That has since changed, and we will look at the basic research explaining the mechanisms of muscle pain in Chapter 4.

In our first meeting, Dr. Kraus asked what I did. I told him that I treated patients with chronic pain.

“How do you do that?” he asked.

“I teach them how to manage their pain, how to deal with it, live with it.”

“Why not get rid of their pain?”

“Because it’s chronic pain,” I said. “You can sometimes reduce it, but you can’t get rid of it.”

He persisted. “Have you treated the muscles?”

“We treat the muscles with aerobic exercises.”

“Aerobic exercises? Really? Muscle pain caused by muscle spasm, tension, stiffness, and trigger points does not respond to aerobics. But it will respond to other types of exercises: prescribed exercises designed to treat the specific source of pain. That’s what I’ve done.”

“Low-impact aerobics are the standard way,” I said.

“They may be the standard way,” he replied. “But they are sure to make many of your patients feel worse.”

He asked if I had “very difficult cases,” and I told him that I did. “Some,” I added, “are impossible to treat.”

“Would you mind if I were to examine one of them?”

End Back Pain Forever: Chapter 2, part 3 #endbackpain

This excerpt from my book End Back Pain Forever, provides a small summary of my early involvement in pain medicine.

Chapter 2

You Are Not Alone: The Back Pain Epidemic (Part 3)

     In 1975, I became a staff physician in the Montefiore Department of Neurology’s Headache Unit, founded by Dr. Arnold Friedman. Two years later, with Dr. Edith Kepes, an anesthesiologist at the hospital, we started the first outpatient pain center in New York City, effectively following the lead of Dr. John J. Bonica, a medical giant to whom we owe the study of pain as a recognized discipline. As a young army anesthesiologist during World War II, he pioneered pain-relieving techniques and treated ten thousand wounded soldiers. Dr. Bonica went on to write a 1,500-page medical classic, The Management of Pain, Dr. Kepes and I began a team approach with practitioners from different fields – including colleagues from anesthesiology, neurology, orthopedic surgery, neurosurgery, physiatry, psychiatry, and psychology – all of whom were interested in what could be done for patients tormented by chronic pain.

I subsequently expanded on this concept by starting the New York Pain Treatment Program at Lenox Hill Hospital in 1983. It was considered a state-of-the-art treatment center in a hospital setting, with an integrated team that involved not only doctors but also physical and occupational therapists, psychologists, and pain rehabilitation nurses. We used a variety of treatments: biofeedback and relaxation training; physical therapy to increase strength, mobility, and endurance; hypnosis to help control pain; stress management to provide coping skills for handling daily upsets that may increase muscle tension; occupational therapy  to teach patients how to complete their routine tasks effectively through proper time management; individual, family, and group psychotherapy to resolve personal difficulties related to living with chronic pain; and medication management to eliminate many ineffective drugs that patients were taking in their journeys from doctor to doctor.

But our program had a basic flaw. We were convinced that teaching people how to live with their pain was usually the best we could do. We didn’t believe that we could eliminate their pain. Many of our patients remained on strong medication indefinitely. If a patient had a 35 percent decrease in pain, I considered that good. If we got it down to 50 percent, it was considered a success.

Along with the vast majority of physicians, I was committed to the fallacy that most chronic pain couldn’t be cured. Then, in 1993, I met Dr. Hans Kraus. He was to transform my life and the life of my patients.

I wrote End Back Pain Forever  to open up a discussion on back pain and provide insights on effective treatments. I have posted the first two chapters of the book on my blog.

 Chapter 2

You Are Not Alone: The Back Pain Epidemic (Part 2)

As a physician specializing in pain medicine, I know how intimately mind and muscles interact. I can literally see a patient’s mental stress in tense, taut muscles. Early on in my training at Montefiore Medical Center in psychosomatic medicine, which is the study of how the mind and body interact, I could see that the separation of mind and body in medical practice made little sense. This drew me to a newly introduced technology, biofeedback, which enabled me to integrate my medical education with my psychiatric practice at the time.

Chapter 2 of End Back Pain Forever delves into the ever-increasing problem of the back pain epidemic. Please review this blog for Chapters 1 and 2 from my book.

Chapter 2

You Are Not Alone: The Back Pain Epidemic

     If you suffer from back pain, you are not alone. The widespread failure by doctors to recognize muscles as the primary source of back pain is helping to fuel an epidemic. Back pain is now the most common disability in the United States. Every year twelve million Americans make new-patient visits to physicians for back pain and a reported one hundred million visits to chiropractors. At the current rate, eight out of ten Americans will experience back pain sometime during their lives.

In addition to the human suffering, medical costs are soaring. The cost of back pain, together with related neck pain, came to $86 billion in 2005, the most recent year for which figures were available. That was an increase of $34 billion from 1997. More amazingly, 25 percent of patients reported being significantly impaired, compared with 20 percent eight years earlier. Spending on back pain now equals the amount spent on cancer and is largely the result of failed surgeries, various nerve block procedures, and the cost of pain medications. We are spending more and getting worse results.
