Leadership development programmes in healthcare research: a systematic review, meta-analysis and meta-aggregation.

Educational methods appeared to be more important for organisational outcomes than specific educational content. To facilitate organisational outcomes, educational methods should include coaching, project work and mentoring. Programmes delivered by external faculty were less likely to be associated with organisational outcomes than those with internal or mixed faculty, but this needs further investigation. Finally, improving evaluation design will allow educators and evaluators to more effectively understand factors which are reliably associated with organisational outcomes of leadership development.
