Purpose/Hypothesis

• Background: Substantial variability exists in outcome measure

reporting in much of the orthopaedic literature

• Aim #1: Quantitatively describe outcome measure utilization in

the SLAP tear literature over the last decade

• Aim #2: Evaluate whether outcome measure utilization relates to

study “quality” – Quality metrics:

• Level of evidence (LOE)
• SCImago Scientific Journal Rank (SJR)
• Hypothesis: Higher quality studies will demonstrate greater
• utcome measure utilization

Methods

Studies reviewed for:

• Journal and study characteristics
• Study demographics
• Clinician Measured Outcomes (CMOs)
• Patient-Reported Outcomes (PROs)
• Other Reported Outcomes (OROs)

Descriptive Analyses (Aim #1):

• Study Demographics
• Outcome Measure Utilization

Univariate Analyses (Aim #2):

• High (I/II) vs. Low (III/IV) LOE
• High (>2) vs. Low (<2) SJR

Methods

Results

Aim #2 SCImago Scientific Journal Rank (SJR):

• Follow-up: High SJR > Low (p=0.046)
• US > among High SJR (p=0.0003)

Level of Evidence (LOE):

• # of CMOs: High LOE > Low (p=0.018)
• PE Findings: High > Low (p=0.003)
• Revision Sx Rate: High > Low

(p=0.036)

• US > among Low LOE (p=0.003)

No difference between high/low SJR & LOE in utilization of or total # of PROs Aim #1

Conclusions

• Considerable variability exists in outcome measure utilization

– Most common PROs: ASES, VAS-Pain, Constant – CMOs are not routinely reported (<1/study) – Complication/Revision Surgery Rates in <50% of studies

• There is little distinguishing higher and lower “quality” studies in
• utcome measure utilization

– Exceptions (LOE): CMOs, PE findings, revision surgery rate Recommendations:

• Improve reporting of complication and revision surgery rates
• Standardize PRO use to enable cross-study comparison
• Raise outcome utilization standards for publication in high impact
