Answer:
The correct answer is: an explanation and an apology.
Step-by-step explanation:
Charles Vincent and his colleagues conducted a study called: Learning from litigation: an analysis of claims for clinical negligence. In this study Vincent et al. investigated which factors lead patients to take legal action against medical practitioners when patients are injured due to medical treatments or procedures, and/or negligence. It was found that various factors may have prevented litigation against medical practitioners such as: correction of the mistake, financial compensation, investigation by the hospital, etc. However, Vincent et al. found that the highest rated action that might prevent litigation​ was when medical practitioners offered an explanation and an apology for their negligence or mistake.
