Objective To provide the evidence on the selection and related policies of essential medicine for policy-makers through systematic review of the National Essential Medicine List(NEML) around the world. Method We systematically searched the official websites of the health authorities, like the departments of health and pharmaceutical administrations. We selected the published NEML. Two reviewers independently selected literature and extracted data. We analyzed the time of NEML published and updated, NEML committees, selection criteria, medicine category, number of medicines, and medicine information in NEML and standard treatment guidelines (STGs) as well. Results Thirty-six NEMLs from 25 countries were included with 34 in English and 2 in Chinese. From 1982 to 2009, Twenty-five countries developed their NEMLs respectively. They were updated from four months to eight years. The NEML committee members came from central government, ministry of health, pharmaceutical administrations, ministry of public health, ministry of education, essential medicine division, etc. The committees were composed of clinical specialists, health officials, pharmacists (pharmacologists), medicine educators, economist, statisticians, epidemiologist and experts from WHO/UNICEF, etc. Most of the countries took the WHO’s concept of essential medicine and selection criteria as standard. The applications of essential medicine were reviewed by considering the following aspects: safety, effectiveness, economic characteristics, the main disease burden, rational use of drug and supply. The medicines in NEMLs of 25 countries varied from 103 to 2 033, and the median is 447. The Anatomical Therapeutic Chemical (ATC) classification was used to classify the medicines in NEMLs of 12 countries. The drug information was provided, including generic name, dosage, form of medication and administration route as well. The STGs or formularies covered from 73 to 167 common diseases, including the diagnosis, treatments, rational use of drug, contraindications, adverse effects, etc. Conclusions The NEMLs in 25 countries have shown great differences because of the variation of the social and economic developments, disease burdens and the developments of health care systems in different countries. We can learn from the experience of other countries, like Australia and South Africa, in the selection and use of essential medicines, STGs and related policies. We should develop the national essential medicine system for policy making and administration, especially the national essential medicine list for common diseases base on the high quality evidence, the local disease burden as well as specific demands in different areas.
In patients with a functionally univentricular heart, the Fontan strategy achieves separation of the systemic and pulmonary circulation and reduction of ventricular volume overload. Contemporary modifications of surgical techniques have significantly improved survival rate. However, the resulting Fontan physiology is associated with high morbidity. Despite large improvements in outcomes of contemporary Fontan patients, a large burden of disease exists in this patient population. In face of the imbalance of medical resources in China and different understanding of Fontan treatment in various regions, there is no consensus on the current status of Fontan strategy, surgical technique and perioperative treatment. By reviewing large amounts of literature, assessing survival rate and risk factors for mortality and complications of the Fontan circulation, knowledge sharing from tens of experts, we achieved a consensus on many aspects of palliation of Fontan. We hope this consensus will help Chinese colleagues further continue their efforts to improve surgical outcomes of the univentricular heart patients.
