The role of the Registered Nurse Mental Handicap (RNLD) within multidisciplinary community support teams was explored within a single county in South Wales. A survey of six community support teams included all members with a professional background. The target population consisted of a total of 96 professionals including RNLDs, social workers, physiotherapists, speech and language therapists, Mencap support workers, psychiatrists and team managers. Each professional was issued with a pre-tested questionnaire that examined their perceptions of their own role and the role of the RNLD. Eighty (83%) completed questionnaires were returned. The results suggested that the RNLDs were seen to contribute five key roles: client based interventions; co-ordination and planning of care; training; care management; and health promotion. Fifty-four per cent of respondents indicated that the role of the RNLD could not be taken by another. The roles and skills of the RNLD and the implications of referral and record keeping methods were discussed.
