The knee joint replacement survey had 19 questions involving improvement in psychological well-being, pain relief, ability to walk different distances, getting rid of a cane, going up and down stairs, kneeling, squatting, using transportation, the ability to be employed, and the ability to participate in recreation, social activities, sports, and sexual activity.
The numbers from each of the questions on the survey were then plugged into a formula that calculated a score ranging from 0 to 100, with 100 being the highest expectation. The study involved 25 patients undergoing THR and 17 patients undergoing TKR. Both patients and doctors completed surveys. The average surgeon expectation score was 75 (range 43 to 93) and the average patient expectation score was 84 (range 47 to 100).
"We observed a lot of variability between what the surgeon expected and what the patient expected. In an ideal world, the expectations of the patient and the surgeon should be similar," Dr. Gonzalez Della Valle said.
Based on results from this pilot study, the National Institutes of Health has awarded Dr. Ghomrawi a five-year career development award. "The hope is to be able to study the relationship between expectation discordance and several outcomes down the road, including rehabilitation outcomes at discharge, and six month and two-year follow-up functional outcomes," Dr. Ghomrawi said. "We are trying to see which items of discordance are clinically meaningful. And then we want to use all this information to improve the doctorpatient dialogue as well as to reassess the class content, so that expectations are aligned."
"The larger study will be more complex. We will try to analyze the discrepancies that different doctors may have for the same patient and that different doctors have between themselves when assessing the same patient," Dr. Gonzalez Della Valle
