Physiotherapist as primary assessor of knee osteoarthritis in primary care
Aim: The purpose of this thesis was to evaluate the feasibility of a 30-second chair stand test as a self-test, to investigate the effects of direct access to physiotherapists on costs and health in people with knee osteoarthritis, as well as to investigate experiences of care among these individuals when physiotherapists serve as the primary assessor.
Methods: This thesis consists of four papers: Paper I investigated intra- and inter-rater reliability and the diagnostic ability of the 30-second chair stand test to function as a self-test for people with knee osteoarthritis (n=114); Papers II-III investigated differences in health outcomes (Paper II) and the cost-effectiveness (Paper III) of a randomized controlled pragmatic trial using a physiotherapist assessment compared with physician’s assessment in people
with knee osteoarthritis in primary care (n=69); and Paper IV used a qualitative interview study to explore the expectations and experiences of a care pathway initiated with a physiotherapist assessment in people with knee osteoarthritis (n=15).
Results: The 30-second chair stand test seems feasible as a self-test with excellent intra-rater reliability and moderate to good inter-rater reliability when comparing self-test results with a physiotherapist assessment.
The differences between physiotherapists and physicians as primary assessors of health outcomes were not significant, and both healthcare pathways resulted in significant improvements in health-related quality of life.
Direct access to a physiotherapist could lead to cost savings with a marginal quality-adjusted life year (QALY) loss.
People seeking care for knee osteoarthritis reported that they expected to be “taken seriously” and receive a proper examination so that they could get the help they needed to get back to their normal physical activities.
The informants viewed physiotherapist and exercise-based treatment as a natural first option.
The knowledge gained from the physiotherapist and the supported osteoarthritis self-management programs were seen as important factors in learning how to self-manage knee osteoarthritis and informants were hopeful that they could return to their normal physical activity level.
Conclusion: The results of this thesis imply that a 30-second chair stand as a self-test is a reliable instrument that can be useful in digital healthcare and selfassessment and that direct access to a physiotherapist could lead to cost savings without significant differences in health outcomes for individuals suffering from knee osteoarthritis.
However, larger studies are needed. Informants who were assessed by a physiotherapist first felt they were understood and gained
the knowledge they needed to self-manage their knee osteoarthritis. They reported feeling hopeful that they could return to their normal physical activities.
