          Abstract

          Patient informed consent for surgery or for high-risk methods of treatment or diagnosis means that unlawful breach of the patient’s personal interests is avoided and the patient accepts the risk of surgery and takes the brunt of it. Patient awareness – their knowledge of the condition and circumstances of continued therapeutic procedure, including offered and available methods of treatment and their possible complications – constitutes a particular aspect of the informed-consent process.

          The rapid development of technologies and methods of treatment may cause communication problems between the doctor and the patient regarding the scope and method of patient education prior to surgery. The use of multimedia technology (e.g., videos of surgical procedures, computer animation, and graphics), in addition to media used in preoperative patient education, may be a factor in improving the quality of the informed consent process. Studies conducted in clinical centers show that with use of multimedia technology, patients remember more of the information presented. The use of new technology also makes it possible to reduce the difference in the amount of information assimilated by patients with different levels of education. The use of media is a way to improve the quality of preoperative patient education and, at the same time, a step towards their further empowerment in the healing process.

          Informed decision making in outpatient practice: time to get back to basics.

          Many clinicians have called for an increased emphasis on the patient's role in clinical decision making. However, little is known about the extent to which physicians foster patient involvement in decision making, particularly in routine office practice. To characterize the nature and completeness of informed decision making in routine office visits of both primary care physicians and surgeons. Cross-sectional descriptive evaluation of audiotaped office visits during 1993. A total of 1057 encounters among 59 primary care physicians (general internists and family practitioners) and 65 general and orthopedic surgeons; 2 to 12 patients were recruited from each physician's community-based private office. Analysis of audiotaped patient-physician discussions for elements of informed decision making, using criteria that varied with the level of decision complexity: basic (eg, laboratory test), intermediate (eg, new medication), or complex (eg, procedure). Criteria for basic decisions included discussion of the nature of the decision and asking the patient to voice a preference; other categories had criteria that were progressively more stringent. The 1057 audiotaped encounters contained 3552 clinical decisions. Overall, 9.0% of decisions met our definition of completeness for informed decision making. Basic decisions were most often completely informed (17.2%), while no intermediate decisions were completely informed, and only 1 (0.5%) complex decision was completely informed. Among the elements of informed decision making, discussion of the nature of the intervention occurred most frequently (71 %) and assessment of patient understanding least frequently (1.5%). Informed decision making among this group of primary care physicians and surgeons was often incomplete. This deficit was present even when criteria for informed decision making were tailored to expect less extensive discussion for decisions of lower complexity. These findings signal the need for efforts to encourage informed decision making in clinical practice.

            A randomised controlled study of an audiovisual patient information intervention on informed consent and recruitment to cancer clinical trials

            Recruitment to cancer clinical trials needs to be improved, as does patient knowledge and understanding about clinical trials, in order for patients to make an informed choice about whether or not to take part. Audiovisual patient information (AVPI) has been shown to improve knowledge and understanding in various areas of practice, but there is limited information about its effect in the cancer clinical trial setting, particularly in relation to consent rates. In this study, 173 patients were randomised to receive either the AVPI, in addition to the standard trial-specific written information, or the written information alone. There was no difference in clinical trial recruitment rates between the two groups with similar study entry rates: 72.1% in the AVPI group and 75.9% in the standard information group. The estimated odds ratio for refusal (intervention/no intervention) was 1.19 (95% CI 0.55–2.58, P=0.661). Knowledge scores increased more in the AVPI group compared to the standard group (P=0.0072). The change in anxiety score between the arms was also statistically significant (P=0.011) with anxiety improving in the intervention arm more than in the no intervention arm. Audiovisual patient information was shown to be a useful tool in improving patient knowledge and anxiety, but further work is necessary in relation to its effect on clinical trial recruitment rates.

              Multimedia patient education to assist the informed consent process for knee arthroscopy.

              In contemporary clinical practice, the ability for orthopaedic surgeons to obtain true 'informed consent' is becoming increasingly difficult. This problem has been driven by factors including increased expectations of surgical outcome by patients and increasing complexity of surgical procedures. Surgical pamphlets and computer presentations have been advocated as ways of improving patient education, but evidence of their efficacy is limited. The aim of this study was to compare the efficacy of a computer-based multimedia (MM) presentation against standardized verbal consent and information pamphlets for patients considering knee arthroscopy surgery. A randomized, controlled prospective trial was conducted, comparing the efficacy of three methods of providing preoperative informed consent information to patients. Sixty-one patients were randomly allocated into MM, verbal consent or pamphlet groups 3-6 weeks prior to knee arthroscopy surgery. Information recall after the initial consent process was assessed by questionnaire. Retention of this information was again assessed by questionnaire at the time of surgery and 6 weeks after surgery. The MM group demonstrated a significantly greater proportion of correct responses, 98%, in the questionnaire at the time of consent, in comparison with 88% for verbal and 76% for pamphlet groups, with no difference in anxiety levels. Information was also better retained by the MM group up to 6 weeks after surgery. Patient satisfaction with information delivery was higher in the MM group. MM is an effective tool for aiding in the provision and retention of information during the informed consent process. © 2010 The Authors.
