Patient-centred care is about sharing the management of an illness between patient and doctor; it is not new but is increasingly evidence-based, especially for chronic problems such as diabetes, asthma and arthritis. Systematic reviews show that patient-centred care results in increased adherence to management protocols, reduced morbidity and improved quality of life for patients. Key features of the doctor-patient interaction are shared goal setting, written management plans and regular follow-up. Supportive community-based services and programs, combined with healthcare system commitment, are also required to make this approach effective in improving population health.
