Patient-derived questionnaire offers moderate, high patient-clinician assessment agreement
Use of a patient-derived questionnaire provided moderate-to-high levels of agreement with clinician assessment, according to study results.
Before their 1-year postoperative visit after shoulder arthroplasty, 120 patients completed a home-based questionnaire containing demographic information, including age, gender, type of surgery, education level and income. The questionnaire included diagram-based questions where patients identified the image representing their own active shoulder range of motion. Researchers also had patients perform a strength examination using premeasured zip-lock bags filled with water that corresponded to predetermined weights up to 2.72 kg. The degree of agreement between the patient’s self-assessment and the clinician’s measures were assessed using κ statistics.
On items related to range of motion, the κ statistics indicated moderate clinician-patient agreement. Results also showed items related to strength had substantial to almost perfect clinician-patient agreement, according to the researchers.
More than 88% of patients correctly estimated their range of motion within one grade of the clinician’s measurement; however, patients tended to err toward overestimating their range of motion, according to the researchers. – by Casey Tingle
