Using bookmarking methods with orthopedic clinicians and patients with fractures produces score interpretation labels for patient-reported outcome measures
Objective
The objective of this study was to determine the patient-reported outcome measure (PROM) score ranges associated with descriptive labels (i.e., within normal limits, mild, moderate, severe) by using bookmarking methods with orthopedic clinicians and patients who have experienced a bone fracture.
Study design and setting
We created vignettes comprised of six items and responses from the Patient-Reported Outcomes Measurement Information System (PROMIS) Upper Extremity Function, Physical Function, and Pain Interference item banks reflecting different levels of severity. Two groups of patients with fractures (
n
= 11) and two groups of orthopedic clinicians (
n
= 16) reviewed the vignettes and assigned descriptive labels independently and then discussed as a group until reaching consensus via a videoconference platform.
Results
PROMIS Physical Function and Pain Interference thresholds (
T
= 50, 40, 25/30 and
T
= 50/55, 60, 65/70, respectively) for patients with bone fractures were consistent with the results from other patient populations. Upper Extremity thresholds were about 10 points (1 SD) more severe (
T
= 40, 30, 25/20) compared to the other measures. Patient and clinician perspectives were similar.
Conclusion
Bookmarking methods generated meaningful score thresholds for PROMIS measures. These thresholds between severity categories varied by domain. Threshold values for severity represent important supplemental information to interpret PROMIS scores clinically.

Detection of coronary calcifications with dual energy chest X-rays: clinical evaluation
Our goal is to assess the ability of physicians to detect coronary calcifications in dual energy chest X-rays processed by a previously developed advanced algorithm. Because the chest X-ray is the most common imaging procedure, because the presence of coronary calcium provides proof of coronary artery disease, and because adherence to therapy can improve health, successful detection could positively impact healthcare for a large number of patients. Both dual energy chest and corroborative CT calcium score images were acquired. Dual energy images were processed with the advanced techniques, including sliding organ registration, so as to enhance coronary calcifications in two-shot dual energy acquisitions. We performed ROC to determine physicians’ ability to detect coronary calcifications. Since detection might be easier with heavier calcifications, we used various Agatston score cut-points for determining cases actually positive with calcification in the ROC analysis. In many cases, coronary calcifications were made more visible with the advanced processing as compared to conventional processing. At an Agatston cut-point of 300, coronary calcifications were detected with AUC = 0.85. There were marginal effects on detection performance found with increased X-ray exposure, nearby Agatston cut-point values, and coronary artery territory. Coronary calcifications can be detected in dual energy chest X-rays. The ability to detect disease compares very favorably to other accepted screening methods (e.g., X-ray mammography). As the chest X-ray is an already ordered procedure, there is an opportunity to detect a very large number of persons with coronary artery disease at zero or low cost.
