Collaborative Model of Care Between Orthopaedics and Allied Healthcare Professionals Trial (CONnACT)

2021. október 6. frissítette: Bryan Tan, Tan Tock Seng Hospital

Osteoarthritis knee is the leading cause of chronic disability among older adults. Our current model of care is doctor-centric and inefficient leading to suboptimal use of allied health intervention for effective lifestyle and behaviour changes resulting in potentially, unnecessary surgery.

The study is designed using an effectiveness-implementation hybrid study design utilizing a mixed methods approach. The hybrid study has dual aims. The primary aim is to evaluate the clinical effectiveness (pain, function and quality of life) of a 12-week multidisciplinary (Orthopaedics, Physiotherapy, Dietetics, Psychology) personalized, community-based program for patients with knee osteoarthritis through a randomized-controlled trial. The secondary aim is to obtain data that will inform the context for implementation and guide future wider scale application. The investigators hypothesize that this multidisciplinary program is clinically more effective in the treatment of knee osteoarthritis at 12 months compared to standard care.

BACKGROUND With a rapidly aging population, osteoarthritis is expected to become the 4th leading cause of global disability by 2020. Established guidelines for knee osteoarthritis strongly advocate lifestyle changes, such with exercises and weight loss as first line of treatment, whilst reserving surgery as the last resort. Our current model of care is doctor-centric and inefficient leading to suboptimal use of allied health intervention for effective lifestyle and behaviour changes resulting in potentially, unnecessary surgery. Redesigning the model of care by moving away from costly surgical treatment through the optimization and synergizing of proven non-surgical treatments is key to deliver value-based care.

AIMS AND HYPOTHESIS Primary Aim and Hypothesis. Evaluate the clinical effectiveness (pain, function and quality of life) at 12 months of a personalized, community based 3-month multidisciplinary program (Orthopaedics, Physiotherapist, Dietitian and Psychologist) as compared with usual care for patients with knee osteoarthritis. The investigators hypothesize that patients with knee osteoarthritis who undergo a personalized, community based 3-month multidisciplinary program will have better pain, function and quality of life scores at 12 months post initiation of program compared to patients who undergo usual care.

Secondary Aim. Evaluate the cost effectiveness of a personalized, community based 3-month multidisciplinary program (Orthopaedic, Physiotherapist, Dietitian and Psychologist) for patients with knee osteoarthritis. Qualitative assessment of the acceptability, feasibility and scalability of such a program

METHODOLOGY The study will be conducted as a single centre, single-blinded, gender stratified, block permutated randomized controlled trial using a mixed method approach (quantitative and qualitative), comparing a proposed new multidisciplinary personalized community-based model of care and the current model of care.

Patients with suspected knee osteoarthritis who are referred from the Polyclinics in the primary healthcare setting to the Tan Tock Seng Hospital Orthopaedic Specialist Outpatient Clinic. Patients will then be evaluated based on the inclusion and exclusion criteria and subsequently invited to join the study if eligible. Consent for participation into the study will be obtained prior to randomization. Randomization will be done via gender stratified permutated block randomization.

ECONOMIC EVALUATION An economic evaluation from a societal perspective will be undertaken to determine the cost effectiveness of the intervention. The incremental cost effectiveness ratio of this multidisciplinary non-surgical community-based program for knee osteoarthritis compared to routine care will be determined. Cost data will be collected via questionnaires and hospital databases to estimate both the direct medical, direct non-medical and indirect cost. Indirect cost of health-related productivity loss due to knee osteoarthritis will be calculated using a human capital approach. The primary measure of health benefit will be Quality of Life Years measure using the EQ-5D.

QUALITATIVE COMPONENT The qualitative component of our study will employ several qualitative methods such as focus group discussions and individual interviews with a variety of subjects including both patients and stakeholders. The focus will on identifying the potential barriers and facilitators to implementing and upscaling the intervention.

Current model of care

Patients will undergo the current standard of care in the Orthopaedic Outpatient Clinic in Tan Tock Seng Hospital. Patients will undergo routine consultation with an orthopaedic surgeon and will be provided with standard treatment as necessitated based on the assessment of the orthopaedic surgeon. Subsequent follow up appointments will be scheduled at the discretion of the orthopaedic surgeon. Patients will be referred to the physiotherapists, dietitian and psychologists as necessary for regular or adhoc sessions at the discretion of the allied health professional.
Egyéb: Current model of care
No controlled set of treatment assigned to patient. It is based totally on the discretion of the attending clinicians. It will generally contain an unspecific number of physiotherapy sessions. Other allied health involvement such as dietetics and psychological interventions will be on an ad hoc basis. In some cases, the orthopaedic surgeon may recommend for surgery.

Időkeret
Knee Injury and Osteoarthritis Outcomes Score (KOOS) subscales - Pain, Symptoms, Activities of Daily Living, Sports/Recreational Activities, Quality of Life
Időkeret: Assessed at baseline, 3 months, 6 months, 12 months
The five patient-relevant subscales of KOOS are scored separately: KOOS Pain (9 items); KOOS Symptoms (7 items); KOOS ADL (17 items); KOOS Sport/Rec (5 items); KOOS QOL (4 items). A Likert scale is used and all items have five possible answer options scored from 0 (No Problems) to 4 (Extreme Problems) and each of the five scores is calculated as the sum of the items included. Scores are transformed to a 0-100 scale, with zero representing extreme knee problems and 100 representing no knee problems
Assessed at baseline, 3 months, 6 months, 12 months
EuroQol-5 Dimensions (EQ-5D)
Időkeret: Assessed at baseline, 3 months, 6 months, 12 months
EuroQol-5 Dimensions (EQ-5D) which consist of 2 dimensions, the EQ-5D descriptive system and the EQ visual analogue scale (EQ VAS). The descriptive system comprises five dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has 5 levels: no problems, slight problems, moderate problems, severe problems and extreme problems. The patient is asked to indicate his/her health state by ticking the box next to the most appropriate statement in each of the five dimensions. This decision results in a 1-digit number that expresses the level selected for that dimension. The digits for the five dimensions can be combined into a 5-digit number that describes the patient's health state. The EQ VAS records the patient's self-rated health on a vertical visual analogue scale, where the endpoints are labelled 'The best health you can imagine' and 'The worst health you can imagine'. The VAS will be used as a quantitative measure of health outcome.
