During the initial postoperative follow-up, researchers asked 153 consecutive patients and their proxies to fill out the Patient Reported Outcomes Measurement Information System PF CAT to assess their perceptions of the patient’s function prior to injury.

 

Here are four key points:

 

1. At an average of 14.3 postoperative days, 50 patient-proxy pairs filled out the PROMIS PF CAT questionnaire.

 

2. The mean PF CAT score for patient perceived preinjury physical function was 57.92.

 

3. The proxy PF CAT score was 56.59.

 

4. The patient and proxy PF CAT scores had an intraclass correlation of 0.79, with a 0.63 to 0.88 confidence internal.
