Computer-based Tutorial as a Means to Enhance the Informed Consent Process for Cataract Surgery

Patients' Attitude Before and After Cataract Surgery, Patients' Information Level About Cataract Surgery

Informing the patient and obtaining the informed consent is one of the major duties physicians perform before beginning a medical treatment. Some years ago we developed the so-called CatInfo programme that allows to inform the patient inter-actively prior to the face-to-face interview with the physician. This program was found to lead to significantly better informed patients in our hospital. Although these findings were significant, we would like to investigate more on two other aspects in this study: Firstly, we would like to learn more about the patients' attitude before and after surgery. Therefore, we would like to ask the patients' about their willingness of being informed and decision making using a standardised questionnaire. Secondly, we would like to investigate on the differences in the duration of informed consent taking in patients that have heard and seen the CatInfo vs. patients received no information prior to the face-to-face interview with the physician. Patients will be randomly assigned to one of these groups. This difference will then be evaluated together with the result of the MCQ (assessing the patients' knowledge concerning cataract surgery after informed consent taking). The primary hypothesis is that patients' are better informed after watching the CatInfo tool although the face-to face interview is shorter.

Informing the patient and obtaining the informed consent is one of the major duties physicians perform before beginning a medical treatment. At the same time expectations of patients in modern medicine grow and so do the legal requirements on informing the patient. Studies have shown that patients often cannot remember the most important and essential parts of the communication with their physician. It also appears that the use of printed information sheets providing patient information has not really changed this situation. By the law of many countries, the duty to inform the patient has to be carried out in a personal face-to face communication of patient and physician. Frequently, the informed consent of the patient is documented by signature on printed forms and only a brief discussion is performed. Additionally, due to the asymmetry in the relationship between patient and physician, patients will often hesitate to ask questions in case of poor understanding of either their diagnosis or the planned procedure. Therefore, the informed consent process may not be sufficient to satisfy the patient's needs. All these factors can result in misunderstandings, poor comprehension of the planned procedure and dissatisfied patients and may eventually lead to litigation. Some years ago we developed the so-called CatInfo programme that allows to inform the patient inter-actively prior to the face-to-face interview with the physician.

Secondly, we would like to investigate on the differences in the duration of informed consent taking in patients that have heard and seen the CatInfo vs. patients received no information prior to the face-to-face interview with the physician. This difference will then be evaluated together with the result of the Multiple choice questionnaire (assessing the patients' knowledge concerning cataract surgery after informed consent taking). The primary hypothesis is that patients' are better informed after watching the CatInfo tool although the face-to face interview is shorter. Patients will be randomly allocated to the study or the control group. Additionally all patients will be called one month after surgery to assess their satisfaction with the informed consent process.
