The aim was to create and validate an audiovisual version of the German matrix sentence test (MST), which uses the existing audio-only speech material. Video recordings were recorded and dubbed with the audio of the existing German MST. The current study evaluates the MST in conditions including audio and visual modalities, speech in quiet and noise, and open and closed-set response formats. One female talker recorded repetitions of the German MST sentences. Twenty-eight young normal-hearing participants completed the evaluation study. The audiovisual benefit in quiet was 7.0 dB in sound pressure level (SPL). In noise, the audiovisual benefit was 4.9 dB in signal-to-noise ratio (SNR). Speechreading scores ranged from 0% to 84% speech reception in visual-only sentences (mean = 50%). Audiovisual speech reception thresholds (SRTs) had a larger standard deviation than audio-only SRTs. Audiovisual SRTs improved successively with increasing number of lists performed. The final video recordings are openly available. The video material achieved similar results as the literature in terms of gross speech intelligibility, despite the inherent asynchronies of dubbing. Due to ceiling effects, adaptive procedures targeting 80% intelligibility should be used. At least one or two training lists should be performed. [ABSTRACT FROM AUTHOR]

- Abstract
Background: Video-assisted patient education (VaPE) has in the past been a subject of many studies. Compared to conventional methods, most authors reported a better transfer of information, some found increased patient satisfaction and a time-sparing effect. There was no increase in anxiety caused by VaPE. Some authors even found a reduction of anxiety levels before anesthesia. All publications to date have focused on the patient's point of view. There have been no reports on how anesthetists as users assess VaPE., Methods: In this study 22 anesthesia departments using VaPE were contacted. A total of 122 anesthetists were sent questionnaires of which 81 (66%) were completed and returned. The anesthetists were first questioned about the characteristics of the workplace, the frequency of preanesthesia patient contacts, the content of the videos, the technique of video presentation and their own professional experience. After this the anesthetists were asked to assess five statements concerning: usefulness of VaPE, economy of time, transfer of knowledge, induction of anxiety and influence on the quality of the consent interview. In each category there were 4 choices: fully agree, partly agree, partly disagree and fully disagree. The first two choices were evaluated as positive and the second two as negative answers. The anesthetists were also asked to state the most valued characteristics of VaPE. Out of eight given options they were to select the most favored three. A final question was whether in their opinion VaPE could be recommended to non-users., Results: Of the anesthetists 97.5% stated that disclosure interviews predominantly took place in the preoperative anesthetic clinic and 73% performed 15 or more patient interviews per day. Videos about general anesthesia were applied by 70%, about non-obstetric regional anesthesia by 56% and about obstetric epidural anesthesia by 59%. The videos were presented to groups of patients via large screens by 27%, individually with CD players or tablet computers by 51% or with both methods (22%). Of the anesthetists 69% had 5 years or more professional experience, 97.5% found VaPE useful for patients education, 92.5% observed a time-saving effect for the following interview and 96% stated that after watching the video patients were better informed. An increase of anxiety caused by VaPE was noted by 46% whereas 54% found no such effect. As to the quality of interview 50% reported an advantage in focusing on the patient's individual risk profile and the other 50% reported no advantage. The ranking of the main advantages was 1) better patient information, 2) time-saving effect, 3) helpful for patient education, followed by 4) increased patient satisfaction, 5) better understanding of anesthesiology, 6) individualization of the interview and 7) helpful in questions of legal liability. The answer option "no advantage" was not chosen at all. Of the participants 82.5% would recommend VaPE unconditionally (fully agree), 17.5% would give a conditional recommendation to colleagues and no one would not recommend VaPE., Conclusion: This survey among anesthetists confirmed most results obtained from patient-based studies: medical users attributed to VaPE a better information transfer and a time-sparing effect. Furthermore, users regarded VaPE as helpful for the preanesthesia interview. As compared to the patient-based results, however, many anesthetists seem to overrate the anxiety, caused by disclosure videos. From the users' point of view, VaPE is a highly appreciated method for patient education which can be recommended to colleagues.
