Included in this category are Health Innovations submissions-reports that showcase the outcomes of initiatives and interventions being tested in clinical and community settings to improve health care quality and delivery, patient safety and satisfaction, and cost efficiency. Consideration is given to the originality of the intervention or initiative, potential to inform others and ability to replicate the results.

Length: 1500 words (6 manuscript pages), not including abstract, references, tables, figures or boxes.
