Abstract
Background: Cardiovascular diseases (CVDs) are the top causes of death worldwide. In China, CVDs affected 29 million patients in 2013, 2.5 million of whom had prior myocardial infarction. Prevention is the best treatment for myocardial infarction. With a variety of pharmaceutical interventions at hand, consumers urgently need a tool to assist them in the decision-making process.
Objectives: A patient decision aid (PDA) comparing preventative treatments for myocardial infarction is developed using methods and techniques of evidence-based and narrative-based Medicine, to fill the gaps in the implementation of these interventions in primary healthcare.
Methods: The PDA contains primarily statistical evidence from synthesis of quantitative study and narrative evidence from synthesis of qualitative study. Steps to generate statistical evidence include: 1) make a list of commonly used drugs for infarction prevention through systematic search; 2) collect original data of pre- and post-market clinical research from open and grey sources; 3) conduct network meta-analysis to compare multiple interventions on outcomes such as efficacy, safety, economics and acceptability; 4) transform statistics into easily comprehensible evidence; and, 5) evaluate the evidence using GRADE Profiler. Steps to generate narrative evidence include: 1) plan in-depth interviews with target consumers; 2) collect stories of searching for medical solutions regarding infarction prevention; 3) analyze and synthesise texts using Altas.ti; and, 4) transform stories into narrative evidence.
Innovative features: Comparisons between single drugs (such as statins) with drug combinations (such as statins and blood-invigorating and qi-tonifying Chinese patent drugs) and comparisons between combined use of western drugs with combined use of western drugs and traditional Chinese patent drugs will be made, to fit in the real-world situation. Narrative evidence may provide psychological support for those in need.
Conclusions: The PDA could be an effective evidence tool to implement preventative measures for myocardial infarction and facilitate shared decision making at the primary care level.
