Performance of PROMIS for Healthy Patients Undergoing Meniscal Surgery

Area of Science:

• Orthopedics and Sports Medicine
• Health Outcomes Research
• Rehabilitation Science

Background:

• The Patient-Reported Outcomes Measurement Information System (PROMIS) developed a comprehensive question bank for computerized adaptive testing (CAT).
• PROMIS Physical Function CAT (PROMIS PF CAT) was evaluated in healthy individuals undergoing meniscal surgery.
• Hypotheses included strong correlation with physical function measures, no ceiling effects, and reduced test burden.

Purpose of the Study:

• To assess the validity and efficiency of the PROMIS PF CAT in patients with meniscal injuries.
• To compare PROMIS PF CAT with established physical function and health-related quality of life instruments.
• To determine the presence of ceiling effects and the test burden associated with PROMIS PF CAT.

Main Methods:

• 107 patients scheduled for meniscal surgery completed PROMIS PF CAT, KOOS, Marx Scale, SF-36, and EQ-5D.
• Correlations were categorized as high (≥0.7), high-moderate (0.61-0.69), moderate (0.4-0.6), moderate-weak (0.31-0.39), or weak (≤0.3).
• Ceiling and floor effects were identified if ≥15% of respondents achieved the highest or lowest possible score.

Main Results:

• PROMIS PF CAT demonstrated high correlations with SF-36 Physical Functioning (r=0.82) and KOOS Sport (r=0.76).
• A significant majority (89%) of participants completed PROMIS PF CAT using only 4 items.
• No floor or ceiling effects were observed, with 0% of participants reaching extreme scores.

Conclusions:

• PROMIS PF CAT strongly correlates with existing patient-reported outcome measures for physical function in meniscal injury patients.
• The PROMIS PF CAT exhibits no ceiling effects in this population.
• PROMIS PF CAT presents a viable, less burdensome alternative to traditional outcome measures for assessing physical function.
