Functional Assessment Instrument Attributes
Description:
An algorithm that assembles items from interRAI assessment instruments (including the US Nursing Home Minimum Data Set) to represent severity of pain.
Author/Sponsor:
Fries BE, Simon SE, Morris JN, Flodstrom C, Bookstein F
Prevalence:
Can be used with all interRAI instruments (nursing home, home care, palliative care, assisted living, etc.)
Population:
Currently used in home care, nursing homes, palliative care, assisted living and other community settings.
Originally derived on a sample of 95 nursing home residents in 25 Medicare-certified facilities in Massachusetts. Prevalence reported on the full population of 34,675 residents in all Michigan nursing facilities from October 1998 – October 1999. In the prevalence sample of post-acute nursing home patients, 47% evidenced pain, while 4% experienced excruciating pain.
Subject:
Patients or residents in multiple settings.
Provider Setting:
Nursing home, home care, assisted living, community settings.
Derived:
Validity and Reliability Testing:
Validated against the Visual Analog Scale. The MDS pain frequency and MDS pain intensity items – used to form the MDS Pain Scale - each had measured inter-rater reliability of 0.73 (weighted kappa – Fleiss-Cohen weights).
Specific vs Multiple Domain:
Verbal or Observation based:
Based on measures of the Visual Analog Scale, which is determined by direct questioning of the individual.
Are calculated scores included:
An algorithm may calculate one or more scores based on elements of the assessment.
Extended use:
Can stand alone for more frequent monitoring of pain than mandated for full MDS or interRAI instruments.
Versions:
Public Domain:
Algorithm is in the public domain. interRAI instruments are copyrighted but license for governments and caregivers to use them is provided via contracts without royalty.
