Outcomes Instruments

Prosk Outcomes Instruments

Patient-Reported Outcomes (PRO) questionnaires or surveys are sometimes referred to as “instruments”. These are different than standard patient satisfaction or many general health surveys. Instruments and scoring methods are designed by panels of accredited medical professionals and specialists. Prosk uses standard, accepted chronic condition surveys and normalized scoring methods associated with each instrument. The patient responses and resulting scores are shown in the Prosk Outcomes Report, showing patient comparison to norms and patient trends can be compared over time.

PROMIS Instruments

Prosk includes general health surveys from PROMIS® (Patient-Reported Outcomes Measurement Information Systems). PROMIS was established in 2004 by the National Institute of Health (NIH) as part of the NIH Roadmap for Medical Research initiative. The PROMIS patient outcomes instruments are a means for Computer Adaptive Testing (CAT) of patient outcomes. PROMIS measures are standardized, allowing for assessment of many patient-reported outcome domains based on common metrics that allow for comparisons across domains, across chronic diseases, and with the general population. One of the goals of PROMIS is to gain a national data pool for outcomes comparison and patient monitoring over time. The following PROMIS instruments are available in Prosk:
Adult Profile– a general health summary of 29 questions survey that covers some of the domain areas with questions about emotional distress, fatigue, pain, physical function, sleep disturbance and participation in social roles.
Global Health Scale– a brief general physical health survey consisting of 10 questions.
Adult Domain Short Forms– there are 8 additional instruments available for each health domain
  • Emotional Distress - Anxiety
  • Emotional Distress - Depression
  • Fatigue
  • Pain - Interference
  • Pain - Intensity
  • Physical Function
  • Sleep Disturbance
  • Satisfaction with Participation in Social Roles

Orthopedics Outcomes Instruments

There are currently two widely-used orthopedic outcomes instruments available in Prosk, with others available soon. Prosk currently has available:
HOOS (Hip Injury Osteoarthritis Outcomes Score)– a 40-question scale survey covering symptoms, daily living functions, pain, recreational activities, and quality of life.
KOOS (Knee Injury Osteoarthritis Outcomes Score)–a 42-question scale survey covering symptoms, daily living functions, pain, recreational activities, and quality of life.
SIS is currently in the process of adding additional AAOS standard surveys, including SMFA (Short Musculoskeletal Function Assessment), ODI (Oswestry Low Back Disability Index) and IKDC (International Knee Documentation Committee) survey. Additional orthopedic instruments are also under consideration.

MDASI Cancer Survey

In addition, Prosk also has the MD Anderson Symptom Inventory (MDASI), available for a fee paid through the University of Texas MD Anderson Cancer Center. The MDASI is a multi-symptom PRO survey of 13 core symptom items that have the highest frequency and/or severity in patients with various cancers and treatment types. The MDASI applies broadly across cancer types and treatments, is easy for patients to complete, includes items related to symptom interference with daily life, and it is easily translated into other languages.
