Interprofessional Preoperative Geriatric Assessment for Older Arthroplasty Patients With Multimorbidity

Study Overview
=================
Brief Summary
-----------------
The objective of this randomized control trial is to investigate effects and cost effectiveness of interprofessional preoperative assessment among older knee or hip arthroplasty patients. The main hypothesis is that preoperative assessment and optimization have a positive impact on the patents' quality of life and expenditure of social and health care services.

Detailed Description
-----------------
Knee and hip arthrosis are common conditions among older adults. Progression of arthrosis often leads to worsening of symptoms and decreased mobility, daily functioning and quality of life. Total joint arthroplasty improves pain in end-stage arthrosis but accustomed postoperative care and rehabilitation alone may not guarantee optimal regain of functioning for frail and vulnerable older arthroplasty patients. Preoperative optimization of older patients with multimorbidity and functional limitations may improve benefits of the arthroplasty even at lower costs. Patients randomized into intervention arm of the present study receive preoperative assessment with treatment and prehabilitation plan. The focuses of the intervention are patient's chronic conditions, nutritional status, medication and physical activity. The intervention is delivered by multiprofessional team (geriatrician, registered nurse, physiotherapist and pharmacist). Older adults undergoing surgery are a rapidly growing but vulnerable patient group. Knowledge on effects of preoperative evaluation and optimization is sparse, especially on the effects of multi-domain interventions.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Health-related quality of life (15-D) | Change in quality of life is measured using the 15-dimensions health-related quality of life questionnaire (15-D) in three time points | Preoperative measurement at baseline, postoperative measurements 3 and 9 months after the arthroplasty. | 
| Costs of social and health care services | Data on the use and costs of social and health care services are obtained from the national and local care registers. The costs of the intervention are evaluated by measuring working time of the inter-professional team members (used per every study patient). | Changes in costs of care are evaluated for a period starting from one year before and ending two years after the baseline examinations. |
