PROMIS in MIS lumbar fusion procedures shows validity: 5 things to know

The Patient-Reported Outcomes Measurement Information System was developed to improve patient-reported outcomes inefficiencies.

A study published in the Journal of Neurosurgery compared results from the system against the Oswestry Disability Index and the 36-Item Short Form Survey to determine its validity for patients undergoing minimally invasive transforaminal lumbar interbody fusion.

Additionally, researchers compared SF-12 physical function and visual analog scale back and leg scores.

Here are five things to know:

1. PROMIS implements computer-adaptive testing that enables the assessment of physical function in fewer questions than the ODI and SF-36.

2. Researchers included patients who underwent primary level 1 or level 2 MIS TLIF proceduresThey excluded patients who had incomplete PROMIS data.

3. Changes in PROMIS physical function scores at six weeks, 12 weeks and 6 months were analyzed and compared against the patient-reported surveys.

4. In all, 74 patients were included in the analysis of the validity of PROMIS. The mean PROMIS score was 35.92 ± 6.98.

5. PROMIS scores revealed significant improvements 12 weeks and six months postoperative. The system showed significant correlation with the SF-12, ODI and VAS leg scores.

"These results suggest that PROMIS scores can be used as a valid assessment of physical function in MIS TLIF patients," the study authors concluded. "Further work is required to determine the full benefit of this measure in other spine populations."
