Signposting services for people with health and care needs: a rapid realist review
Authors: Cantrell Anna , Booth Andrew , Chambers Duncan

Background
Signposting typically refers to an informal process that involves giving information to patients to enable them to access external services and support. It is perceived to reduce demand on primary care and other urgent care services.

Methods
This focused realist review was conducted rapidly within time constraints. Searches to identify theory were undertaken on MEDLINE, Cumulative Index to Nursing and Allied Health Literature and Social Sciences Citation Index in June 2022 for research published in English from 2016. We selected 22 publications and extracted programme theories from these to develop three priority questions:

Question 1: What do people with health and social care needs require from a signposting service to believe it is valuable?
Question 2: What resources do providers require to confidently deliver an effective signposting service?
Question 3: Under what circumstances should commissioners commission generic or specialist signposting services?

Purposive searching was conducted to find a rich sample of studies. UK studies were prioritised to optimise the applicability of synthesis findings.

Results
The review included 27 items, 4 reviews and 23 studies, a mix of qualitative, evaluations and case studies.
Service users value a joined-up response that helps them to navigate the available resources. Key features include an understanding of their needs, suggestion of different options and a summary of recommended actions. Only a small number of service user needs are met by signposting services alone; people with complex health and social care needs often require extended input and time.
Front-line providers of signposting services require appropriate training, ongoing support and supervision, good knowledge of relevant and available activities and an ability to match service users to appropriate resources. Front-line providers need to offer a flexible response targeted at user needs.
Commissioned signposting services in England (no studies from Scotland, Wales and Northern Ireland) are highly diverse in terms of client groups, staff delivering the service, referral routes and role descriptions. A lack of service evaluation poses a potential barrier to effective commissioning. A shortage of available services in the voluntary and community sector may limit the effectiveness of signposting services. Commissioners should ensure that referrals target intensive support at patients most likely to benefit in the longer term.

Conclusions
Signposting services need greater clarity of roles and service expectations to facilitate evaluation. Users with complex health and social care needs require intensive, repeat support from specialist services equipped with specific knowledge and situational understanding. A tension persists between efficient (transactional) service provision with brief referral and effective (relational) service provision, underpinned by competing narratives. Do signposting services represent ‘diversion of unwanted demand from primary care/urgent care services’ or ‘improved quality of care through a joined-up response by health, social care and community/voluntary services’?

Limitations
This realist review was conducted within a tight time frame with a potential impact on methodology; for example, the use of purposive searching may have resulted in omission of relevant evidence.

Future work
Signposting services require service evaluation and consideration of the issue of diversity.
