A call for action: improving decision-making in the commissioning of health services

27 Oct, 16 | by BMJ Clinical Evidence

While evidence based medicine (EBM) has been promoted for over 20 years and has influenced other disciplines like nursing, little attention has been paid to decision-making in NHS clinical commissioning: the planning and purchasing of services to meet the healthcare needs of the local population.
