Plain English Summary

Background and study aims
Osteoarthritis (OA) is the most common type of arthritis, affecting millions of people worldwide. It occurs when the protective cartilage on the end of bones wears away. The bones then rub against one another, causing stiffness, pain and a reduction in the range of movement. One of the most effective ways to treat long-term illnesses is by giving the sufferer the tools and skills to manage their conditions day-to-day. NICE provides extensive guidelines for self-management of OA however it has been found that they are not always used in standard care. Generally, people are willing to participate in self-management of their condition, however many people feel that they need more support from healthcare professionals to do this. It is thought that by providing GP’s with the necessary tools to support self-management of OA could help more people to manage their condition effectively. Using a special template the consultations given to people suffering from OA could make consultations more consistent (model OA consultation, MOAC); ensuring that self-management of the disease is successfully promoted by healthcare professionals. The aim of this study is to find out whether the MOAC is a practical way of promoting self-management of OA.

Who can participate?
GP surgeries which are members of West Midlands North PCRN or a Keele Research Network Practice, and adults with a diagnosis of OA who attend these practices.

What does the study involve?
The study is made up of two parts. In the first part of the study, the existing care that is given to OA sufferers is monitored in all participating GP surgeries by reviewing patient records and completing questionnaires with patients and healthcare professionals. In the second part of the study the participating GP surgeries are randomly allocated into two groups. For those in the first group (intervention group), healthcare professionals receive additional training to help them to better implement the OA treatment recommendations. Patients at these practices are also given an information book to help them manage their condition. Surgeries in the second group (control group) do not receive any additional training and provide only usual care to patients. At the end of the study period, patient notes are reviewed in both groups to assess the standard of care being given.

What are the possible benefits and risks of participating?
Although no direct benefit from taking part in this study can be guaranteed, what we learn from the study should help us to treat people with osteoarthritis in the future.
People with joint problems do occasionally feel that even filling in a brief questionnaire can cause some discomfort, although this should be short-lasting and does not indicate any underlying change in their condition. If an interview topic brings back unhappy memories or distressing thoughts that participants do not wish to discuss, the topic will not be followed up again during the interview.

Study information

Scientific title

Management of Osteoarthritis in Consultations Study: the development of a complex intervention in primary care (MOSAICS): a pilot cluster randomised controlled trial



Study hypothesis

The MOSAICS Study is a mixed methods study which investigates the feasibility, acceptability and impact of implementing a new approach to supporting self management for osteoarthritis (OA) in primary care.
1. To develop and pilot a new model of supported self management [i.e. a Model OA Consultation (MOAC) and guidebook] in primary care
2. Carry out a cross sectional survey of the local population to establish current uptake of NICE core recommendations in people aged 45 years and over with joint pain
3. Carry out anonymised medical record reviews to describe the current patterns of management of OA in primary care, and to describe any change in management following introduction of a structure template to support a model OA consultation.
4. Carry out an evaluation of the new approach using qualitative interviews and structured observations with patients and the primary healthcare team.

Topic: Primary Care Research Network for England, Musculoskeletal; Subtopic: Not Assigned, Musculoskeletal (all Subtopics); Disease: Musculoskeletal, All Diseases


A Joint Pain/OA Consult Temp: Template developed to record Quality Indicators for OA. To be used as part of routine consultations for patients presenting with a working diagnosis of OA (knee, hip, hand and foot) in primary care; A Model OA Consultation, a three pronged 'Model OA Consultation' has been developed and will be implemented in the four intervention practices.

The model includes consultation with the GP, consultation with the practice nurse, (educational intervention and self management support) and an opportunistic consultation with other health care professionals. An osteoarthritis guidebook, developed using national guidelines and experiential knowledge by a multi disciplinary group in collaboration with patients living with OA. The patient guidebook will be used as a resource for self care management of their OA, and to act as a reinforcement of verbal information given by health care professionals during the model consultation sessions.

Training packages for health care professionals (HCPs) in the intervention practices will receive training developed from
1. The results of two previously conducted consensus exercises on the consent and style of a model OA consultation and
2. theoretical models to guide self management of OA.
