Duration

Definition: How long the pain has been experienced and continues to be present (lasting minutes or hours).

Clinical Use:

  • This information is critical for evaluating the effectiveness of the treatment plan.
  • Duration of pain can be gathered as part of a comprehensive history of the pain as well as each time pain is assessed.

Frequency

Definition: The number of occurrences in a specified period of time; how often pain is experienced in a given time period.

Clinical Use:

  • Knowing the frequency of pain is useful in developing treatment strategies and for individualized scheduling of care activities.

Intensity (or Severity)

Definition: The older adult’s descriptive rating of "how bad" the pain is.

Clinical Use:

  • Ask about pain intensity in the present (‘right now/currently’).
  • To identify temporal trends, "ask the older adult to identify their pain intensity at its worst (‘worst pain’) as well when their pain intensity is at its best (‘the best the pain gets’) over a specified period of time, such as ‘in the past week’.
  • Assessing the older adult’s present ("right now") pain rating and an identified pain rating acceptable to the older adult is also important.
  • Use the most appropriate pain self-report scale individualized to the older adult’s cognitive and sensory abilities and culture.

Location

Definition: Anatomic site(s) of pain.

Clinical Use:

  • Older adults often have pain in more than one location.
  • Identify and document all sites with corresponding intensity and character.
  • Pain maps are very useful in documenting all pain locations, guiding therapy, and as a tool in providing daily care (e.g., CNAs can use the pain map to establish the least painful ways to turn and/or ambulate the person they’re working with).

Onset

Definition: Description of the experience of the beginning of the pain.

Clinical Use:

  • Described as sudden or gradual development of the pain, associated with a known injury or illness. 
  • Asking about onset can also help identify pain triggered by specific movement or activity.
  • Asking about onset can also help to distinguish between acute and persistent pain.

Pattern/Predictability (or Rhythm)

Definition: The course of the pain over time including variations, often influenced by times of day (e.g., certain hours of the day, night or day, monthly patterns), periods of rest, or specific or general activity/movement.

Clinical Use:

  • May be constant and/or episodic pain.
  • Analgesic therapy should be tailored to these patterns.
    • For example, short-acting analgesics are most appropriate for episodic pain, whereas long-acting agents are best for constant pain. Routinely dosed, short-acting agents may work well as an alternative to long-acting opioids in older adults.
  • Older adults with both constant pain and episodic increases in pain (i.e., breakthrough pain) need both short-acting and long-acting medications.

Quality (or Character)

Definition: Description of the characteristics of the pain, preferably in the words used by the older adult to describe the pain.

Clinical Use:

  • Helpful in determining the type of pain to guide the most appropriate analgesic.
  • If the older adult has difficulty describing the pain, it may be helpful to offer examples of descriptions: aching, sore, cramping, pounding, sharp, throbbing, dull, nagging, penetrating, shooting, numb, tingling, spasm, burning, gnawing, pressure-like, radiating, stabbing, tingling, tender, knife-like, etc.
  • May assist in distinguishing between type of pain: acute, persistent, and neuropathic.
