About this study
Official title: Quality of Life, Functional Outcomes and Costs in Patients Undergoing Primary Total Knee Arthroplasty
This prospective observational study aims to collect and analyse data on functional outcomes, quality of life indicators, and costs in patients undergoing primary total knee arthroplasty (knee replacement) surgery.
Read the detailed description
Primary total knee replacement surgery (also called primary total knee arthroplasty) has been shown to be a safe and reliable procedure for the treatment of degenerative joint disease, which can improve the functional and overall quality of life among patients. This prospective observational study aims to explore how undergoing these surgeries affects patients' functional outcomes and quality of life indicators. Another purpose of this research is to evaluate the costs that generate from this surgical intervention and relate them to the gains in functional outcomes and quality of life measures by conducting cost-utility analysis (CUA).
Participants of this study will be men and non-pregnant women over the age of 18 who are undergoing primary total knee replacement surgery at the Traumatology, Orthopedics and Joint Pathology Clinic of the I.M. Sechenov First Moscow State Medical University (Sechenov University). At this facility, around 500 total knee replacement surgeries are performed annually.
Functional outcomes and quality of life indicators will be measured with validated questionnaires. The Western Ontario and McMaster Universities Arthritis Index (WOMAC) will be used to measure functional outcomes in patients undergoing knee arthroplasty, the 5-level version of the EuroQol-5 Dimension questionnaire (EQ-5D-5L) will be used to measure their health-related quality of life. Questionnaires will be administered to patients before they undergo the procedure and on several follow-up dates (6 weeks, 3 months, 6 months, 1 year after the procedure). Before the surgery the questionnaires will be provided to patients in print form. At other points in time the questionnaires will be administered over the phone or via online forms (way of questionnaire administration depends on the choices of patients).
In addition to tracking changes in patients' functional outcomes and quality of life indicators, patients will be surveyed about all direct and indirect costs generated from seeking treatment for their condition, undergoing the replacement surgery, and the rehabilitation process. A small sample of patients will be interviewed about the costs borne by them to produce a questionnaire which will be used to survey the other patients. Cost information will be collected at the same points in time and in the same formats as stated above (printed questionnaires, telephone surveys, online forms). Financial data for calculating costs borne by the clinic will be obtained from the cost accounting system of the facility after each patient's discharge. Afterwards, the collected cost information will be applied to the CUA. Using quality-adjusted life-years (QALYs) and monetary estimates of costs, Average Cost-Utility Ratios (ACURs) will be calculated for primary total knee replacement surgeries.

What is being measured
The primary outcome is the main question the study is designed to answer.
Change in cost-utility of the primary total knee arthroplasty
As part of the cost-utility analysis (CUA), the Average Cost-Utility Ratio (ACUR) will be calculated for each time frame after the surgery. ACUR is equal to average health-related costs generated over a time frame divided by average Quality-Adjusted Life years (QALYs) gained over the same time frame. Health-related costs will include all direct and indirect costs before and after surgery (from questionnaires administered to patients and financial data taken from the cost accounting system of the facility). Data on health-related quality of life collected using the EuroQol-5 Dimension questionnaire (EQ-5D-5L) will inform the QALYs calculation.
Measured: Baseline (before surgery), 6 weeks after surgery, 3 months after surgery, 6 months after surgery, 12 months after surgery
Change in functional outcomes measured by total scores of the Western Ontario and McMaster Universities Arthritis Index (WOMAC) questionnaire
The WOMAC questionnaire consists of 24 questions. The overall WOMAC score (index) is determined by summing the scores across the three dimensions of pain (score ranges from 0 to 20), stiffness (score ranges from 0 to 8), and physical function (score ranges from 0 to 68).
Measured: Baseline (before surgery), 6 weeks after surgery, 3 months after surgery, 6 months after surgery, 12 months after surgery
Change in quality of life indicators measured by the 5-level version of the EuroQol-5 Dimension questionnaire (EQ-5D-5L) health profile (state), index and the visual analogue scale score (EQ VAS)
The EQ-5D-5L questionnaire consists of 5 questions in 5 domains: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. In the 5-level version of the questionnaire, each domain has 5 levels. The 5 answers to the 5 questions are combined into a 5-digit number that describes the patients' health profile (state). The 5-digit number can be converted into a single summary index value, which reflects how good or bad a person's health is relative to the general population of a country or region. Another part of the questionnaire is the EQ-VAS which records the patients' self rated-health on a scale from 0 to 100, where 0 = the worst imaginable health and 100 = the best imaginable health.
Measured: Baseline (before surgery), 6 weeks after surgery, 3 months after surgery, 6 months after surgery, 12 months after surgery
Secondary outcomes (1)
Level of patients' satisfaction with the primary total knee arthroplasty procedure and overall treatment at the facility
This outcome measure consists of patients' answers to two questions:
- Patients will be asked to rate their level of satisfaction with the surgery, treatment provided at the clinic and their overall experience at the facility on a 0-10 numeric rating scale, where 0 = lowest level of satisfaction and 10 = highest level of satisfaction.
- Patients will be asked whether they would choose to undergo this surgery at the same facility again if they had to (yes/no question).
Measured: Up to 7 days after the surgery
