Interprofessional education: effects on professional practice and health care outcomes.
BACKGROUND
As patient care becomes more complex, effective collaboration between health and social care professionals is required. However, evidence suggests that these professionals do not collaborate well together. Interprofessional education (IPE) offers a possible way forward in this area.


OBJECTIVE
To assess the usefulness of IPE interventions compared to education in which the same professions were learning separately from one another.


METHODS
We searched the Cochrane Effective Practice and Organisation of Care Group specialised register, MEDLINE (1968 to 1998) and Cinahl (1982 to 1998). We also hand searched the Journal of Interprofessional Care (1992 to 1998), the Centre for the Advancement of Interprofessional Education Bulletin (1987 to 1998), conference proceedings, the 'grey literature' held by relevant organisations, and reference lists of articles.


METHODS
Randomised trials, controlled before and after studies and interrupted time series studies of IPE interventions designed to improve collaborative practice between health/social care practitioners and/or the health/well being of patients/clients. The participants included chiropodists/podiatrists, complementary therapists, dentists, dietitians, doctors/physicians, hygienists, psychologists, psychotherapists, midwives, nurses, pharmacists, physiotherapists, occupational therapists, radiographers, speech therapists and/or social workers. The outcomes included objectively measured or self reported (validated instrument) patient/client outcomes and reliable (objective or validated subjective) health care process measures.


METHODS
Two reviewers independently assessed the eligibility of potentially relevant studies.


RESULTS
The total yield from the search strategy was 1042, of which 89 were retained for further consideration. However none of these studies met the inclusion criteria.


CONCLUSIONS
Despite finding a large body of literature on the evaluation of IPE, these studies lacked the methodological rigour needed to begin to convincingly understand the impact of IPE on professional practice and/or health care outcomes.
