The size, extent and nature of the learning disability nursing research base: a systematic scoping review.
BACKGROUND
A research base should be of sufficient quality and quantity to inform nursing practice. It must allow nurses to access information about clients' needs and to identify effective strategies for meeting those needs. This paper presents the findings of a scoping review of 'learning disability nursing research'. The review aimed to determine whether there is a research base sufficient to support learning disability nursing practice.


METHODS
We undertook searches of the Cochrane Library and electronic databases (Medline, Psychinfo, Embase, CINAHL and British Nursing Index) for the years 1996-2006. Full references and abstracts were downloaded for papers returned. Papers considered relevant to the topic of the review were organised into three categories according to whether the main focus of the research was people with learning disabilities, carers or family members, or nurses. For each paper, information about the locality of the research, the topic of the research, design/method and sample size was extracted.


RESULTS
We identified 180 relevant research studies, most of which made use of convenience samples of less than one hundred people. Very few studies evaluated the clinical impact of nursing interventions or the delivery of care by learning disability nurses. A small number of studies examined the impact or patient experiences of nurse-led interventions. These tend to small-scale evaluations of new service initiatives, such as the management of behavioural problems. Overall there was an absence of strong evidence about the effectiveness of specific nursing interventions.


CONCLUSIONS
The extent of learning disability nursing research is limited in quantity and it is difficult to draw comparisons across research studies. Much of the available evidence is drawn from small-scale evaluations; which may provide useful guidance and inspiration for service development but do not, in themselves, constitute a sufficient body of research evidence to support learning disability nursing practice.
