Reading Pain Scores in the Medical Record

At 0200, the night nurse charted the patient’s pain as 2/10. Fifteen minutes later, her narrative note described her as restless, grimacing, and holding her head, saying she had the worst headache of her life. By 0600, she was in the operating room with a ruptured cerebral aneurysm.

Which entry is accurate? That’s the question the attorney asks the LNC to answer.

If you review medical records for attorneys, you’ve seen pain documented half a dozen ways.

• A 0–10 number in the emergency department.
• A row of cartoon faces on the pediatric unit.
• A CPOT score in the ICU.

Each tool measures something slightly different, and each one is valid only for certain patients.

Once you know those rules, pain scores start telling you what the staff saw, when they knew it, and what they did about it.

Pain documentation matters in two aspects of a case. On liability, the questions are whether pain was assessed, recognized, appropriately treated, and reassessed. On damages, the question is how much the patient suffered and for how long.

When the Patient Can Tell Staff: Self-report Pain Scores

A patient’s own report is the reference standard for pain. If the patient can communicate, their rating counts more than the nurse’s impression of how they look. Three self-report tools show up most often.

Numeric Rating Scale (0–10). Zero means no pain; 10 means the worst pain imaginable. This is the default in most adult charts, from the ED to the post-op floor. It works well for alert adults who understand numbers.

Verbal Descriptor Scale. The patient picks a word: none, mild, moderate, severe. Some facilities use it for older adults who find numbers abstract. It’s less precise, so trends are harder to read.

Wong-Baker FACES. Six faces run from smiling to crying, scored 0, 2, 4, 6, 8, and 10. It was designed for children age 3 and older. It’s also used with adults who have language barriers or mild cognitive impairment.

Here’s the detail many reviewers miss: FACES is a self-report tool. The patient points to the face that matches how they feel. The nurse is not supposed to match a face to the patient’s expression. When you see “FACES 4” beside “patient appears comfortable,” ask who actually chose that face.

Check the ranges

Not every facility uses a 0–10 range. Some flowsheets use 0–5, and some score the faces 0–5 instead of 0–10. A 5 on a 0–5 scale is the top of the range, not a moderate score. Find the flowsheet legend or ask for the facility’s pain documentation policy before you interpret any number.

What a complete self-report entry includes

A number alone isn’t a pain assessment. Look for the staff’s notations on:

• Location and quality (sharp, burning, cramping, pressure)
• Onset, duration, and what makes it better or worse
• The patient’s acceptable pain level or functional goal
• The intervention and a follow-up score

When the Patient Can’t Tell Staff: Behavioral Scales

Intubated, sedated, delirious, demented, and preverbal patients can’t give you a number. For them, nurses score observable behavior instead. These tools estimate whether pain is present. They don’t measure intensity the way a self-report does, so a CPOT of 4 is not the same as “4/10.”

The Society of Critical Care Medicine’s PADIS guideline names the Behavioral Pain Scale (BPS), its non-intubated version (BPS-NI), and the Critical-Care Pain Observation Tool (CPOT) as the most valid and reliable options for ICU adults who can’t self-report. The same guideline says vital signs are not valid pain indicators on their own. A rising heart rate should prompt a real assessment.

Tool	Used for	What it scores	Range	Commonly cited threshold
CPOT	ICU adults, intubated or not	Facial expression, body movements, muscle tension, ventilator compliance or vocalization	0–8	Above 2 suggests pain
BPS	Intubated ICU adults	Facial expression, upper limb movement, ventilator compliance	3–12	Above 5 suggests pain
BPS-NI	Non-intubated ICU adults	Vocalization replaces ventilator compliance	3–12	Above 5 suggests pain
PAINAD	Advanced dementia	Breathing, negative vocalization, facial expression, body language, consolability	0–10	Higher score, more likely and more severe pain
FLACC	Young children (about 2 months to 7 years) or nonverbal patients	Face, legs, activity, cry, consolability	0–10	Higher score, more pain

Newborns have their own tools, including NIPS, CRIES, and N-PASS. If your case involves a NICU stay, look up the specific scale the unit used.

Sedation changes everything

Behavioral scales depend on the patient being able to move, grimace, or fight the ventilator. Two situations make them unreliable:

• Neuromuscular blockade. A chemically paralyzed patient can’t grimace or move. A CPOT of 0 on a paralyzed patient tells you nothing about pain. Look for analgesia and sedation ordered alongside the paralytic.
• Deep sedation. Check the sedation score, usually RASS, recorded near each pain score. A patient at RASS −4 or −5 shows little behavior to score.

When you see a pain score, always look at the sedation score charted at the same time. The two belong together.

Red Flags to Look for in the Record

Pain scores are rarely inaccurate on their own. The problems show up when you compare them against everything else in the chart.

The number and the narrative disagree. “Pain 0/10” next to “moaning, guarding, diaphoretic” is a contradiction worth flagging. So is a low score while the family’s complaints that their loved one is in constant pain appear in a social work note.

The wrong tool for the patient. A 0–10 score on an intubated, sedated patient raises an obvious question: how did they give that number? Watch for “unable to rate” with no behavioral scale documented at all.

Identical scores, shift after shift. The same score at the same times across several days can point to copy-forward charting rather than a fresh assessment.

“Sleeping” charted as zero. Patients can sleep with pain. After opioids, a sleeping patient may also be over-sedated. Look for a sedation assessment, not just a pain score.

No reassessment after a PRN dose. Compare the MAR to the pain flowsheet. Each as-needed dose should have a follow-up score within the time frame the facility’s policy sets.

Rising scores with no escalation. Pain that climbs despite treatment, or pain out of proportion to the injury, can signal compartment syndrome, bowel ischemia, an epidural hematoma, or a cardiac event. Note when the trend started and when someone called the provider.

A scale that changes mid-stay. Switching from CPOT to 0–10 to FACES makes trends hard to read. Note each switch and the reason, if one is given.

Vital signs used as the pain assessment. “HR 88, appears comfortable” is not a validated pain assessment for a patient who can’t self-report.

How Pain Documentation Plays Out in the Case

The same pain entries can help either plaintiff or defense, depending on what they show.

For the plaintiff, pain is often the earliest warning sign of a complication. A record that shows climbing scores, no reassessment, and a late call to the provider supports a failure-to-recognize or failure-to-escalate claim.

For the defense, thorough documentation can show the team used the right tool, treated the patient promptly, and observed improvement. A clean trend of scores dropping after each intervention is strong evidence of reasonable care.

For damages, pain scores help establish conscious pain and suffering. The defense may argue a critically ill patient was unaware in the hours before death. A CPOT of 5 paired with a light sedation score tells a different story than a deeply sedated patient with no behavioral response.

Build a pain timeline

When pain is central to the case, pull every pain entry into one chronological table for the attorney. It turns scattered flowsheet rows into a story the attorney can follow in minutes.

Gaps jump out once the entries sit side by side: the missing reassessment, the score that contradicts the note, the eight hours with no entry at all.

The Questions to Ask Every Time

Whenever you meet a pain score in the record, run through four questions:

1. Was this the right tool for this patient at this moment?
2. Does the score match the narrative, the sedation level, and the rest of the chart?
3. What did the staff do about it?
4. Did anyone check whether it worked?

Those answers often matter more than the number itself. Attorneys rarely know the difference between a CPOT and a FACES score. Your ability to explain it clearly is exactly what they’re paying you for.
