The Importance of Pain Assessment in Geriatric Care
Accurately assessing pain in older adults presents unique challenges due to age-related sensory deficits, cognitive impairments, and a tendency to underreport pain. A comprehensive approach involves not just asking about pain, but also observing behaviors and consulting with caregivers. Choosing the right tool for the individual's cognitive and communication abilities is a cornerstone of effective pain management.
Self-Report Pain Scales for Cognitively Intact Seniors
For older adults who can clearly communicate, self-report remains the gold standard for pain assessment. Several scales are widely used and validated for this population.
The Numeric Rating Scale (NRS)
This is perhaps the most straightforward and commonly used scale. A person rates their pain on a scale of 0 to 10, where 0 means "no pain" and 10 means "worst pain imaginable." Its simplicity makes it easy for many older adults to understand and use, as long as they are cognitively intact and have good comprehension.
The Verbal Descriptor Scale (VDS)
Instead of numbers, the VDS uses a series of descriptive words to represent pain intensity. Patients are asked to choose the word that best describes their current pain level, such as "no pain," "mild pain," "moderate pain," "severe pain," and "pain as bad as it could be." This can be more reliable than the NRS for some older adults who struggle with abstract numerical concepts.
The Wong-Baker FACES Pain Rating Scale
Originally developed for children, this scale uses a series of six facial expressions to help patients communicate their pain. The faces range from a happy, smiling face (0 = No Hurt) to a crying, distressed face (10 = Hurts Worst). While effective for some older adults with mild to moderate cognitive impairment, its reliance on emotional expression can sometimes be misleading for patients with severe cognitive decline.
Behavioral Pain Scales for Those with Limited Communication
For older adults with moderate to severe dementia or other conditions that impair communication, observational or behavioral pain scales are essential. These tools rely on a trained caregiver observing the patient for specific behaviors that indicate pain.
The Pain Assessment in Advanced Dementia (PAINAD) Scale
Specifically developed for individuals with advanced dementia, the PAINAD scale assesses five key behaviors that may signal pain. A clinician observes the patient and scores each behavior from 0 to 2, with a total score ranging from 0 to 10. The five items are:
- Breathing: Changes from normal breathing patterns.
- Negative Vocalization: Moans, groans, or cries.
- Facial Expression: Frowning, grimacing, or showing sadness.
- Body Language: Fidgeting, tense movements, or rigid posture.
- Consolability: How the patient responds to verbal or physical comforting.
The Pain Assessment Checklist for Seniors with Limited Ability to Communicate (PACSLAC-II)
The PACSLAC-II is another robust observational tool that provides a more comprehensive checklist of behaviors indicating pain. It includes a wide range of observable actions related to facial expressions, verbalizations, body movements, changes in activity patterns, and social interactions. A higher score on the checklist suggests an increased likelihood of pain, and tracking changes over time can help determine treatment effectiveness.
Mobilization-Observation-Behaviour-Intensity-Dementia (MOBID-2) Pain Scale
The MOBID-2 scale is unique because it specifically assesses pain during movement, which is often when pain is most apparent. It involves observing the patient during five different standardized, guided movements during routine morning care. The caregiver rates the intensity of pain behaviors using a numerical scale (0-10) during each movement.
A Comparison of Common Pain Scales for Seniors
| Feature | Numeric Rating Scale (NRS) | Wong-Baker FACES Scale | Pain Assessment in Advanced Dementia (PAINAD) |
|---|---|---|---|
| Best Used For | Cognitively intact individuals | Older adults with mild to moderate cognitive impairment | Individuals with advanced dementia or severe cognitive impairment |
| Method | Self-report (verbal) | Self-report (visual) | Observational |
| Items Assessed | Numerical rating (0-10) | Faces and verbal descriptions | Breathing, vocalization, facial expression, body language, consolability |
| Scoring | 0-10 | 0-10 (via faces) | 0-10 (sum of 5 items, 0-2 each) |
| Key Advantage | Simple and easy to understand | Provides a visual aid | Effective for non-verbal patients |
| Limitation | Not suitable for cognitive impairment | Can be misinterpreted by some cognitively impaired | Cannot confirm true pain intensity (as it's observational) |
A Comprehensive Approach to Pain Management
Effective pain management in the elderly extends beyond simply choosing the right scale. The American Geriatrics Society (AGS) recommends a hierarchical approach to pain assessment. This involves:
- Prioritizing Self-Report: Always attempt to get a self-report first, even with cognitively impaired patients, using simplified scales or questions.
- Looking for Potential Causes: Consider any underlying conditions or procedures that are likely to cause pain.
- Observing Behaviors: Systematically use a reliable behavioral pain scale like PAINAD or PACSLAC-II.
- Involving Caregivers: Gather information from family members or consistent caregivers who know the patient's baseline behavior.
- Conducting an Analgesic Trial: If pain is suspected, a time-limited trial of a pain medication can help confirm if the behavior is pain-related.
Challenges in Assessing and Managing Pain
Despite the availability of tools, several barriers persist. Pain is often seen as a normal part of aging, strong pain medications are sometimes feared, and health professionals may lack adequate training in geriatric pain assessment. Furthermore, observational tools can be subjective, and a patient's inability to express pain does not mean they are not experiencing it.

Conclusion
Identifying what pain scales are used for elderly people is a vital step toward improving the quality of life for this vulnerable population. By using a combination of self-report and observational tools, caregivers and healthcare professionals can create a more accurate and compassionate pain management plan. Moving beyond the myth that pain is an inevitable part of aging, and using validated assessment tools, allows for more effective treatment and better outcomes for seniors.
