Is Your Pain Tolerable?

By Pat Anson, PNN Editor

There has long been controversy over the way pain is measured by healthcare providers. Critics say the two most widely used methods, the numeric 0 to 10 pain scale and the Wong Baker Pain Scale, are too subjective because they rely on patients to self-report their pain levels.

Some even claimed that asking patients about their pain encourages excess opioid prescribing. There was never any evidence to support that argument, but in 2017 the Centers for Medicare and Medicaid Services (CMS) caved into political pressure and dropped three survey questions that asked Medicare patients about the quality of pain care they received in hospitals.   

A new method of measuring pain is now being proposed, one that is designed to reduce opioid prescribing and other pain treatments. It hinges on a simple question:

“Is your pain tolerable?”

In a new study published in JAMA Network Open, researchers say asking patients that question could help doctors decide whether opioids and other treatments are really necessary.

"Because of concerns about overtreatment of pain with opioids there has been an enormous effort to rethink how we ask patients about pain," says lead author John Markman, MD, director of the Translational Pain Research Program at the University of Rochester Medical Center.

"Knowing that patients consider their pain to be tolerable, physicians wouldn't necessarily prescribe a medication with serious risks or expose them to surgery.”

Markman and his colleagues asked 537 primary care patients if their pain was tolerable, and then had them rate the intensity of their pain on the 0 to 10 scale.

Most patients who had mild pain (a score of 1 to 3) or moderate pain (4 to 6) said their pain was tolerable. Even with a severe pain score of 7, nearly 40% said their pain was tolerable. But after that, at level 8 or higher, severe pain becomes less and less tolerable.

“Our findings confirmed the intuitive assumption that most patients with low pain intensity find their pain tolerable,” Markman wrote. “In contrast, the tolerability of pain rated between 4 and 6 varies substantially among patients. In this middle range, if a patient describes pain as tolerable, this might decrease the clinician’s inclination to initiate higher-risk treatments.  A substantial subgroup of patients with severe pain reported their symptoms as tolerable.”

One weakness of the tolerable question is that it measures pain at a single point in time – and chronic pain patients often experience flares that can make their pain intolerable. It also assumes that every patient is alike and has the same level of tolerance.

Markman says numeric pain scales have "very little relevance" when patients who have lived with chronic pain for several years visit their doctors.

"If, instead, a patient could say 'my pain is tolerable when I'm doing this but intolerable when I'm doing that,' and it's in the context of that patient's life, I frankly think that's much more useful, and is what doctors really want to know," Markman said.

"In order to transform how we treat pain to make treatments safer and more effective, we need to start with a reformation in how we ask patients about pain."

What Does Your Pain Feel Like?

By Pat Anson, Editor

Does your chronic pain feel like you’ve been hit with a hammer, a bad sunburn that won’t go away, or ants crawling under your skin?

Those are some of the choices patients have in a new campaign launched in Ireland to change the way patients describepain to their physicians.   

Accurately assessing pain is difficult because pain is so subjective. For many years doctors have relied on various versions of the Wong Baker Pain Scale – a series of sad and smiling faces a patient chooses from to help their doctor understand how much pain they are in. The scale is so simple it was originally developed for children, but is now used around the world for adults.

The “Mypainfeelslike…” campaign aims to improve on that method by using more descriptive images and phrases to help doctors understand and diagnose their patient’s pain. The campaign focuses on neuropathic pain, but can be used for many other types of chronic pain. The initiative is sponsored by Grunenthal Group, a German pharmaceutical company.

Instead of an unhappy face, patients can choose from a dozen images, ranging from a burning flame to a rope tied in knots to a set of ice cubes. They also fill out a questionnaire and select different phrases to describe their pain, such as “a hot iron on my skin” or “a volcano erupting.”

Patients are also asked to fill out a questionnaire to select different phrases to describe their pain, such as “a hot iron on my skin” or “a volcano erupting.” And there's a list of multiple choice answers to describe how pain affects their ability to work, exercise and socialize.

It may take a few minutes to complete the questionnaire, but the idea is to get patients to “invest more time and accurateness in thinking about their symptoms, describing them more precisely, and preparing for doctors’ appointments.”

“Doing so forces us to reconsider our chronic pain, and the different ways that we feel it. This improves our self-awareness, allows us to better communicate our situation, and helps us get the most value out of the very short time that we usually have during doctors’ appointments,” the website says.

According to a survey by Grunenthal, over half of Irish pain sufferers feel frustrated when trying to communicate their pain to a doctor. Over a quarter say they delay discussing their pain because they’re not sure how to do it.

“Living with chronic or nerve pain affects people’s well-being, their ability to be independent, their productivity and relationships, which can lead to feelings of depression," John Lindsay, chair of Chronic Pain Ireland told the Irish Independent.  “The ‘Mypainfeelslike…’ campaign will help raise awareness of the impact of chronic pain and give people living with this disease the tools to re-evaluate their pain management plans.”
