Innovation in healthcare: a systematic review of recent research.

Research on innovations in healthcare organizations published between 1994 and 2004 are here reviewed and summarized. The majority of the 31 identified studies dealt with the adoption of innovations and new practices and were cross-sectional designs applying quantitative methods, or multiple case studies applying qualitative methods. Five pathways for future research are recommended: (a) Multilevel approaches studying innovation simultaneously on individual, group, and organizational levels; (b) a combination of quantitative and qualitative data; (c) use of longitudinal designs (innovation both as the dependent and independent variable); (d) application of experimental designs in interventions; and (e) exploration of innovation generation and structural innovations.
