The Association Between Patient-Reported Outcome Measurement Scores and Preference for Specific Interventions.

To determine whether greater patient-reported symptom intensity and functional limitation influence expressed preferences for discretionary diagnostic and treatment interventions, we studied the association of patient factors and several Patient Reported Outcome Measure (PROM) scores with patient preferences for diagnostic and treatment interventions before and after the visit, a cross-sectional cohort study. One hundred and forty-three adult patients who completed several PROMs were asked their preferences for diagnostic and treatment interventions before and after a visit with an orthopedic surgeon. Patients with better physical function had fewer preferences for specific diagnostic interventions after the visit (P = .02), but PROM scores had no association with preferences for treatment interventions before or after the visit. A greater percentage of patients expressed the preference for no diagnostic or treatment intervention after the visit with a physician than before (diagnostic intervention; 2.1% before vs 30% after the visit; P ≤ .001 and treatment intervention; 2.1% before vs 17% after the visit; P ≤ .001). This study suggests that physician expertise may be more reassuring to people with more adaptive mind sets.

Satisfaction With Specific and Nonspecific Diagnoses.

PURPOSE: Nonspecific upper extremity illnesses (eg,. wrist pain, forearm pain)-where no objectively verifiable pathology is detectable-are common and usually self-limiting. For some patients, a nonspecific diagnosis can contribute to mistrust and disappointment. METHODS: This study tested the primary null hypothesis that there is no difference in mean overall satisfaction between patients given a specific compared with a nonspecific diagnosis. Second, we assessed factors associated with satisfaction and with nonspecific upper extremity diagnosis. RESULTS: There was no significant difference between mean satisfaction with nonspecific and specific diagnoses in bivariate analysis. However, when treated as a categorical variable, 22% of the patients with a nonspecific diagnosis had a satisfaction score of 8 or lower compared with 11% of the patients given a specific diagnosis. First visit and greater pain intensity were significantly associated with a nonspecific diagnosis in bivariate analysis. In the multivariable models, no factors were independently associated with satisfaction or with nonspecific diagnoses. CONCLUSIONS: Although nonspecific diagnoses can sometimes be frustrating for both physician and patient, in this small study using a satisfaction measure with a strong ceiling effect, they were no less satisfying to patients on average and corresponded with slightly greater pain intensity than specific diagnoses. CLINICAL RELEVANCE: The degree to which nonspecific diagnoses (perhaps in combination with compassionate care and incremental monitoring) can be part of a satisfying treatment experience merits additional investigation.

Latissimus dorsi transfer to restore external rotation with reverse shoulder arthroplasty: a biomechanical study.

In patients with pseudoparesis of the shoulder resulting from irreparable rotator cuff tears, reverse shoulder arthroplasty (RSA) can restore active elevation, but external rotation remains less predictable. Latissimus dorsi transfer (LDT) has been shown to be effective in restoring external rotation in patients with posterosuperior tears of the rotator cuff. The aim of this study is to determine the capacity of the LDT to restore external rotation in combination with RSA and to investigate the mechanical advantage produced by 3 different insertion sites. A biomechanical model was created using a reverse total shoulder prosthesis with 3 different transfer insertions. Moment arms were measured for 2 static positions and 1 motion of the humerus. The moment arm analysis showed that LDT can improve active external rotation in the setting of a reverse prosthesis. An insertion site on the posterior side of the greater tuberosity (adjacent to the teres minor insertion) produced a greater external rotation moment arm.
