Increased out-of-pocket costs have led to patients bearing more of the financial burden for their care. Previous work has shown that and distress can affect outcomes, symptoms, satisfaction, adherence treatment. We asked following questions: (1) Does patients' correlate with disability in nonacute orthopaedic conditions? (2) Do patient demographic factors this correlation?We conducted a cross-sectional, observational study new presenting multispecialty clinic complication. Patients completed...

Shared decision-making between patients and physicians involves educating the patient, providing options, eliciting patient preferences, reaching agreement on a decision. There are different ways to measure shared decision-making, including involvement, but there is no consensus best approach. In other fields, have been varying relationships patient-perceived involvement observed in decision-making. The relationship has not studied orthopaedic surgery.(1) Does correlate with measurements of...

Background Complex regional pain syndrome (CRPS) occurs in 2 to 8% of patients that receive open or endoscopic carpal tunnel release (CTR). Because CRPS is difficult treat after onset, identifying risk factors can inform prevention. We determined the incidence following and CTR using a national claims database. also examined whether psychosocial conditions were associated with CTR. Methods accessed insurance diagnostic procedural codes. calculated within 1 year. The response variable was...

Introduction. Shared decision making involves educating the patient, eliciting their goals, and collaborating on a for treatment. Goal elicitation is challenging physicians as previous research has shown that patients do not bring up goals own. Failure to properly elicit patient leads increased misconceptions decisional conflict. We performed randomized controlled trial test efficacy of simple goal tool in improving involvement making.

Outcomes in rectal cancer are dependent on tumor height. Modalities for assessing height include MRI, endoscopy, and digital exam (DRE). We seek to identify correlations between these modalities. Retrospective analysis of 120 patients at a single institution. Correlation coefficients distance the anal verge DRE were compared by region. The distances (cm) from were: MRI: 6.2 ± 3.0, endoscopy: 5.9 2.9, DRE: 5.4 2.4 (p = 0.238). Endoscopy strongly correlated with MRI (spearman coefficient 0.899...
