According to the available data, in these days, the number of medical accidents and disputes have significantly increased since 1990 in Korea. From this aspect, a variety of approaches and efforts to solve these problems is needed before it is too late. This study intended to identify the thoughts of patients who are directly connected with medical accidents and disputes and then to consider reasonable settlement methods of the increasing disputes. For achieving the purpose of this study, the self-administerd questionnaire was conducted with 450 out-patients who visited three university hospitals, five small and medium-sized hospitals, and ten clinics in Seoul from June 13 to 17, 2005. Incomplete questionnaires were omitted and 410 respondents(91%) were included for the analysis of this study. Each section of the survey was composed of six categories such as the recognition of malpractice, a compensation system about no-fault medical accidents, the recognition of the judgement of medical accidents in court, reasonable settlement of medical accidents, reasons of lawsuit, and the need of the medical dispute settlement organization. The major results of this study were as follows. First, more than half of the respondents, 51.9 percent, worry about malpractice. And many respondents think malpractice causes their symptoms to persist or become worse, and also some respondents think that the doctor's prescription changed too frequently. Second, as for a compensation system about no-fault medical accident, 55.7 percent of the respondents insist that a proper compensation for suffering patients or their families should be provided. And also as for the responsibility of compensation, respondents think joint compensation of both the medical institution and the government is needed foremost, followed by the medical insurance company and finally by the medical institution. The government as well as the related institutions should take responsibility for malpractice accidents for which the doctor is not responsible. Third, as for the acknowledgment of medical accident judgements by the court, 32.8 percent of respondents think that it is best to compromise with a medical institution, followed by lawsuit(26.2%), the assistance of civil organization(23.2%), and a powerful physical protest(7.6%). Fourth, as for the lawsuit of medical accidents, 62.9 percent of respondents think that patients and their families would be in a disadvantageous position in relation to medical institutions and doctors mentioning the lack of professional medical and lawful knowledge, experience and know-how as the reason. So many people have given up appeals owing to the difficulties involved in defending themselves through evidence. Fifth, about a half share of the respondents indicated that the medical institution's neglect of the responsibility of medical accidents is one of the most important reasons of lawsuit. And next respondents mentioned the lack of the medical dispute settlement organization and a general distrust of medical institutions and doctors. Sixth, a majority of respondents consented to the introduction of the need of the medical dispute settlement organization, And about a half of the respondents mentioned a readiness to accept the mediation of the organization, but the rest did not express a clear opinion. It seems that conflict among the parties concerned have existed in relation to the medical dispute settlement organization and related legislation for many years. But as this study has shown, the needs of the medical dispute settlement organization is in desperate demand. Therefore, more negotiation efforts from all interest groups should be considered for the birth of the medical dispute settlement organization and related legislation.
