Alternative dispute resolution, or ADR, is the practice of resolving disputes through processes other than litigation. The most common forms of ADR are mediation and arbitration, but many other forms exist in the Health Care arena to address specific types of disputes and their need for tailored processes for unique situations. Some of these include hearing officers for hospital hearings, referees for discovery disputes and early neutral evaluation of cases. Lawyers specializing in the Health Care field are required to utilize many skills, techniques and methods to resolve disputes for their clients. Health Care lawyers must remain up-to-date on regulatory changes, industry trends, the economic climate and changes in the law.
