A pain score helps us hear the patient. It does not tell us the diagnosis, select an analgesic, or decide whether discharge is safe. The useful question is what the pain means for this person and what should change after treatment. The treatment discussion here concerns adults.
Pain is an experience, not a monitor reading
Nociception is the processing of potentially harmful stimuli; pain is the person’s sensory and emotional experience. The two are related but not interchangeable. Biological, psychological and social influences shape pain, and persistent pain need not imply continuing tissue damage. None of this makes the suffering less real. IASP definition and notes.
Acute pain can accompany sympathetic activation, but heart rate and blood pressure have many other determinants. Normal observations cannot invalidate a pain report. Conversely, unexplained tachycardia still requires assessment for physiological threats rather than being attributed to pain alone.
In a retrospective study of more than 150,000 ED patients aged 16 or older, vital-sign differences across pain-intensity groups were too small to substantiate an individual’s reported pain. This was observational evidence, not a test of analgesic efficacy. Daoust and colleagues.
What the fifth-vital-sign debate actually teaches
The historical campaign sought to make undertreated pain visible. The VA toolkit already described screening as the start of broader assessment, treatment and follow-up, and included function and patient-defined relief. It did not simply instruct clinicians to prescribe until every score reached zero. VA toolkit.
A before-and-after study in one VA outpatient clinic found no improvement in measured care processes after implementation. That finding concerns implementation in one setting; it neither proves that pain assessment is useless nor establishes that documenting scores caused the opioid crisis. Mularski and colleagues.
Use the score, then ask what it misses
When patients can report pain, start with their account. Use language they understand and a suitable numeric, verbal or faces self-report scale. If communication prevents reliable self-report, use a population-appropriate observational tool and clinical context. Quiet behavior or inability to speak does not establish comfort. IASP notes.
Pain scales are usable measures, despite being subjective. A prospective adult ED study supported the validity of a verbally administered numerical scale. That does not turn a reported number into an objective measure of tissue injury. Bijur and colleagues.
Use the same scale when trending an individual’s pain where possible: strong correlation between two scales does not guarantee agreement for that patient. Holdgate and colleagues.
Ask about onset, location, quality, provoking factors, associated symptoms, previous treatment and what the pain prevents. A low score does not exclude dangerous disease. Pain that changes character or no longer fits the working diagnosis should reopen the assessment.
Relieve suffering and restore useful function
Agree on a meaningful goal, such as breathing deeply after a chest-wall injury or tolerating necessary examination. Ask whether relief is acceptable to the patient. Function complements their report; it is not a test they must pass to deserve analgesia. Use timely, condition-specific multimodal care, combining suitable comfort measures with pharmacological or regional options. AAEM guidance.
For adult discharge prescribing, many common acute conditions respond to nonopioid treatment. Opioids still have a role when expected benefit exceeds risk, including some severe acute pain. Choose the individual plan rather than prescribing automatically from a score or withholding indicated relief until every alternative fails. The CDC outpatient guideline excludes sickle-cell, cancer-related, palliative and end-of-life pain; it is not an in-ED dosing protocol. CDC guideline.
Reassess benefit, harm and the diagnosis
After treatment, reassess at a time appropriate to the intervention’s onset and the patient’s condition. Record pain, the agreed functional goal and adverse effects. With opioids, reassess alertness and respiratory status before further titration; a lower pain score accompanied by unsafe sedation is not a successful endpoint. AAEM guidance.
Persistent or worsening pain calls for a fresh examination and reconsideration of the cause, not just another dose. Improvement also does not, by itself, exclude dangerous pathology. Stabilization, diagnostic work-up and humane relief should proceed together.
Before discharge, explain the working diagnosis, expected course, medication plan, follow-up and condition-specific reasons to return. If prescribing an opioid, address interactions with sedating substances, driving, safe storage and disposal, and overdose risk; offer naloxone, particularly when overdose risk is increased. CDC safety recommendations.
A useful bedside standard
Document what mattered: the patient’s description, the clinical concern, treatment, benefit, harm and next step. Keep pain assessment connected to action. The number is one part of that conversation, and relief remains an important outcome.
