Evidence-based mental health care and implementation science in low- and middle-income countries.

Although the evidence base for what to do about the mental health gap in low- and middle-income countries (LAMICs) has improved significantly over the last decade, mental health care in LAMICs still provide services to only a small minority of people with mental disorders. The problem is how to translate the relevant body of scientific knowledge into routine practice. It is clear from over two decades of research that the creation of evidence-based guidelines is necessary but not sufficient for evidence-based practice, whether in high- or low-income settings. In this Editorial, I discuss whether the recent development of 'implementation science' may offer an opportunity towards effective guideline implementation in low- and medium-income settings, so that clinical practice is more often based on evidence that does lead to patient benefit.
