Ouch! Whose Pain Feels Worse?

1 Comment

levels-of-evidenceIs pain experience as diverse as our populations?  This week I came across an interesting meta-analysis.

A meta-analysis (MA) is one of the strongest types of evidence there is. Some place it at the top; others, 2nd after evidence-based clinical practice guidelines.  (For more on strength of  evidence, click here.)

MA is not merely a review of literature, but is a statistical integration of studies on the same topic.  MA that is based on integration of randomized controlled trials experiment(RCTs) or experimental studies is the strongest type of MA.  MA based on descriptive or non-experimental studies is  a little less strong, because it just describes things as they seem to be; & it cannot show that one thing causes another.

MA example: This brand, new MA included 41  peer-reviewed, English-language, experimental studies with humans:  Kim HJ, Yang GS, Greenspan JD, Downton KD, Griffith KA, Renn CL, Johantgen M, Dorsey SG. Racial and ethnic differences in experimental pain sensitivity: Systematic review and meta-analysis. Pain. 2016 Sep 24 [Epub ahead of print] doi: 10.1097/j.pain.0000000000000731. PMID: 27682208.    All 41 studies used experimental pain stimuli such as heat, cold, ischemic, electrical and others and compared differences between racial/ethnic groups.

Pain reliefMain findings?  “AAs [African Americans], Asians, and Hispanics had higher pain sensitivity compared to NHWs [non-Hispanic Whites], particularly lower pain tolerance, higher pain ratings, and greater temporal summation of pain.” (https://www.ncbi.nlm.nih.gov/pubmed/27682208)  (Temporal summation is the increase in subjective pain ratings as a pain stimulus is repeated again and again.)

Critical thinking:  Given that this is a well-done meta-analysis and that the pain was created by researchers in each study, how should this changequestion your practice?  Or should it?   How can you use the findings with your patients?  Should each patient be treated as a completely unique individual? Or what are the pros & cons of using this MA to give us a starting point with groups of patients?  [To dialogue about this, comment below.]

Happy evidence hunting. -Dr.H

Afraid to Relieve Pain? You may have Opiophobia

Leave a comment

fear5In pain management are you afraid to give comfort to your patients with appropriate medications?   Are you afraid to be comforted when in pain?  Have you encountered families or care partners, who are afraid to comfort their loved one in pain by giving pain medications?

In a classic 2002 qualitative study, “Fearing to Comfort,” Zerwekh, Riddell, & Richard identified that RNs, physicians, patients, families, and health systems were afraid to relieve pain with appropriate use of pain medications.  They were Not doing evidence-based practice, but fear-based practice. barrier

Fear barriers include, but are not limited to 1) patients’ fear of addiction, fear of distracting the MD from the main treatment plan, and loss of control; 2) MDs’ avoiding the needs of the dying, fear of rewarding drug-seekers, or equating pain management with euthanasia; 3) RNs’ avoiding pain, failing to switch to palliative goals at end of life,  and fear of killing the patient; 4) families’ fears of addiction, side effects, & killing their loved one; and 5) health facilities’ not giving unique consideration to those at end of life, inadequate staffing, & time constraints (Zerwekh et al., 2002).

This is an issue because irrational problems cannot be simply solved by giving rational Pain fistinformation.   We have to find evidence-based practices that can create a change of heart, if you will.  As Zerwekh et al wrote: “Because fear is so influential in decisions to keep pain under control, palliative educational approaches must go beyond providing information to fill deficits in palliative knowledge.”
We must learn evidence-based ways to overcome fear and control pain.  Why?  Because pain interferes with living life.  Who are we protecting when we fear appropriate pain medications?  Not the patient.

FearRemedy?  Palliative care education must confront the fears and remove them through cognitive restructuring that includes learning to question beliefs about addiction etc.  Role playing, role modeling, and an expert walking through this with the provider or family who is afraid.  Beyond this helping people to recognize their own fears of pain & death, and providing the very best available information on pain management (Zerwekh et al).

CRITICAL THINKING:  Have you been afraid?  Or seen others afraid?  How can you solve this problem using evidence-based practice that = BEST available evidence + Clinical judgment + Patient/family preferences & values? Be specific because if you haven’t yet encountered the problem of fearing to comfort, be assured that you will.fear4

“IT’S A PAIN!” Use Evidence to Address Pain Management Myths

1 Comment

A new threat has emerged in evidence-based management of pain control.  Fear.

Evidence-based practice for pain control has 3 elements:  BEST available evidence + Clinical judgment + Patient/care partner values and preferences.

In the concern over opioid abuse by some patients & professionals, some federal agencies and nonprofits are suggesting that The Joint Commission (TJC) is inadvertently at fault (http://hosted.ap.org/dynamic/stories/U/US_PAINKILLERS_PAIN_MEASURES?SITE=AP&SECTION=HOME&TEMPLATE=DEFAULT).  HCAHPS questions are also under suspicion.

Pain fistWhile I am not an apologist either for TJC or HCAHPS, my fear is that the government/involved nonprofit fears ignore the data: pain relief is still inadequate for some patients, professionals often under-medicate or don’t believe patients, and some patients have pain crises.  Limiting opioids only to certain diagnoses undercuts evidence-based care.

As a professional RN, you need to check out the best available evidence yourself, use your judgment, and Question1practice pain assessment & management safely. We knowIdea2 that asking patients about suicidal intent does not cause them to commit suicide.  Does asking patients about pain cause them to have it or to treat pain they don’t have?  Hmmm…..

Here are the current TJC standards:  1) The hospital educates all licensed independent practitioners on assessing and managing pain. 2) The hospital respects the patient’s right to pain management. 3) The hospital assesses and manages the patient’s pain.”

Check out this link for truth about the following 5 myths identified by TJC about their standards:  http://www.jointcommission.org/joint_commission_statement_on_pain_management/

  • Myth#1: The Joint Commission endorses pain as a vital sign…. Vital sign
  • Myth #2: The Joint Commission requires pain assessment for all patients….
  • Myth #3: The Joint Commission requires that pain be treated until the pain score reaches zero….
  • #4: The Joint Commission standards push doctors to prescribe opioids….
  • OxycodoneMyth #5: The Joint Commission pain standards caused a sharp rise in opioid prescriptions. This claim is completely contradicted by data from the National Institute on Drug Abuse.”…  [Source=TJC link above]

Of course, RNs & the health team can always do things better, and the above concerns Hypothesissuggest that we might need new studies. I hope only that we won’t jump on the fear bandwagon.   Keep practice EVIDENCE BASED, listen to patient/carepartner preferences & values, & use your judgment.  

CRITICAL THINKING:  How do you assess patient pain?  How could you improve?  How do you apply TJC standards in your setting?
