Plain English summary of protocol

Background and study aims
People living with Atypical Parkinsonian Syndromes (APS) often experience complex symptoms that affect movement, thinking, mood, vision, eating, and communication. These individuals quickly become reliant on family and carers and require specialised clinical care to maintain their quality of life and avoid unnecessary hospital admissions. However, access to services varies significantly across the UK, leading to inequalities in care. This study aims to understand what aspects of current health and social care provision influence these inequalities, how service configuration affects people's ability to live well with APS, and how care can be improved within the existing system.

Who can participate?
1. People living with APS
2. Carers of people with APS
3. Health, social care and voluntary organisation professionals involved in supporting people with APS

What does the study involve?
The study will:
1. Review policies, guidelines, and services relevant to people with APS (a realist review).
2. Interview people with APS and their carers about their experiences accessing and navigating services.
3. Speak to professionals about the challenges of delivering care.
4. Map networks and services available in different locations, using a system design approach.
5. Hold two workshops with participants and collaborators to explore solutions and co-design a questionnaire for future research.
6. In the long term, develop a new model of care based on findings, to inform a follow-on evaluation of practical strategies.

What are the possible benefits and risks of participating?
Benefits:
1. Participants can contribute to improving services for people with APS.
2. Carers and patients can share their experiences to help influence positive change.
3. Professionals may help identify and remove barriers in care provision.
Risks:
1. Discussing personal experiences may be emotionally challenging.
2. Time commitment may be a burden for some participants.

Scientific titleCo-designing improvements to systems of care and support to tackle inequality of access for people with Atypical Parkinsonian Syndromes: combining a system approach and realist review to inform a discrete choice experiment
Study acronymImprove APS
Study objectivesAims:
1. To explore the diversity of experiences that people with APS and their carers have with access and use of health and care services, understanding the context and complexity of provision in specific locations in England
2. To co-design system improvement recommendations based on available assets that can address people’s needs and preference, reduce disparities, and improve the responsiveness of health and social care in providing coordinated services

This will be achieved by:
1. Building programme theories of what works, for whom and why using realist methodology
2. Asking people affected to share their experience of access and navigation of the current system to create a map of networks and services, guided by the Engineering Better Care system design toolkit
3. Understanding the current system strengths and involve service users and providers to create a questionnaire for a follow-up study using a Discrete Choice Experiment approach
4. To disseminate results co-creating material with public contributors

Health condition(s) or problem(s) studiedAtypical Parkinsonian Syndromes
InterventionThe project will be conducted over 24 months. It combines realist methodology with an engineering-informed systems approach to understand the factors affecting the provision of care and support to people affected by APS. This approach will enable us to understand what works, for whom and why in six areas of England. Exploration of inequalities of access will provide the knowledge base for a future preparation and evaluation of system improvement guidance.

Age groupAdult
Lower age limit18 Years
SexAll
Target number of participants56
Key inclusion criteria1. People with mental capacity and ability to communicate.
2. People providing consent to participate of all genders, age, ethnicity, socio economic background, location.

Patients’ cohort:
People with mental capacity (according to carer/family) and ability to communicate, affected by APS, selected at different stages:
1. People at a moderate stage of the APS disease, 2-3 years from diagnosis, to capture information regarding diagnosis and initial care and referrals, and to obtain their views while still able to communicate.
2. People at later stage of the APS disease, >3 years.

Carers’ cohort:
1. Defined as someone who cares for, supports or provides help to someone affected by APS, either family member, relative, paid carer, close friend or neighbour on a regular basis for at least 2 years.
2. Carers of deceased people (<1 year to avoid recall bias) in order to capture information about the majority of the pathway through the care system.
3. Carers able to represent their relative/employer and consenting to also share their own experience of caring for people with APS.

Health care, social care and charity staff cohort:
Staff with or without experience of liaising with people affected by APS, but aware of barriers and facilitators of access to services for people with APS.
Key exclusion criteria1. People with multi-morbidities that affect function (mild cognitive impairment, dementia, speech and language impairment, frailty), other conditions that would prevent participations to the study.
2. People who refuse consent after initial meeting or during the study.

Publication and dissemination planThis project will generate the following outputs with potential utility to other researchers:
1. Realist review and synthesis of literature on policies, guidance, and examples of provision of services for people with APS. It will be available as protocol and as review summary as soon as completed and submitted to publication into realist evaluation/service improvement/policy journals.
2. Transcripts of interviews/focus groups and qualitative data analysis: when data collection will be completed, these will be stored on encrypted files located in the sponsor servers, plus will be made available (to be explored further) as requested by the funder, e.g., through online open access repository. They will be anonymised and made available, with consent by study participants.
3. System mapping: a publication will explain how the data collected contributed to the creation of the system map of networks. This material will be of interest to journals exploring system methodologies and service improvement.
4. Workshops transcripts: as above, transcripts will be stored as per sponsor regulations and available via an online open access repository.
5. Overall process and results: a creative galleria (published on the sponsor/funder webpages or with a specific DOI) will show the overall process and results, it will be publicly available and printable for participants and the public who may not be digitally literate. It will be available at study completion.
6. Public and professional collaborators will be invited to disseminate results via publications, reports and conferences related to methodological approaches, care services, rare diseases, integrated care, and long-term neurological conditions. Newsletters for special interest groups and professionals.
7. Output will also include feedback to participants (via blogs, feedback materials, charity websites, support meetings attendance), service users and providers (clinical and health & social care services conferences), producing lay material and participating in charities’ events for the dissemination of study results to the wider condition-specific community and the public.
