Abstract

A device consisting of a hearing protector headset and a modified hearing aid is used as a protective hearing aid for normal hearing subjects. Understanding of sufficiently redundant speech is remarkably improved, especially for noise level of about 20 dB above speech level. Tests have been made with the "Freiburger Zahlentest" and amplified "party noise" up to noise levels of 105 dBSPL. As an example: the above mentioned device enables the wearer to understand speech of 85 dB with 105 dB loud speech similar background noise while still the ears are charged with no more than 90 dB at all. Application for hyperacusis and recruitment patients is discussed.

Effective hand hygiene education with the use of flipcharts in a hospital in El Salvador.

In developing countries, continuing education for healthcare staff may be limited by staff shortages and lack of sophisticated means of delivery. These limitations have implications for compliance with an important infection control practice, namely good hand hygiene. A comparison was made between the efficacy of two educational tools commonly used in healthcare and practical sanitation settings in developing countries, i.e. videotapes and flipcharts, in delivering hand hygiene education to 67 nurses in a paediatric hospital in El Salvador. Efficacy was measured on the basis of scores obtained in pre- and post-training tests consisting of 10 multiple-choice questions. Half of the nurses received video-based instruction and half received instruction via flipcharts. Both methods of instruction increased participants' knowledge of good hand hygiene, and the extent of knowledge acquisition by the two methods was similar. Feedback obtained from flipchart users six months after training indicated that most of the respondents used the flipchart to teach hand hygiene to patients' families (62.5%), patients (50%) and healthcare workers (43.8%). Flipchart users ranked flipcharts as their favourite educational tool. Flipcharts offer an economical, easy-to-use, non-technological yet effective alternative to videotapes for delivering education in developing countries. Although the use of flipcharts requires a skilled and well-trained instructor, flipcharts could be used more widely to deliver education in resource-poor settings.

Use of pictorial aids in medication instructions: a review of the literature.

PURPOSE: The effects of pictorial aids in medication instructions on medication recall, comprehension, and adherence are reviewed. SUMMARY: Many patients depend on medication labels and patient information leaflets for pertinent drug information, but these materials are often difficult for patients to understand. Research in psychology and marketing indicates that humans have a cognitive preference for picture-based, rather than text-based, information. Studies have shown that pictorial aids improve recall, comprehension, and adherence and are particularly useful for conveying timing of doses, instructions on when to take medicine, and the importance of completing a course of therapy. Other research has compared various techniques for using picture-based information and supports the use of integrative instructions, a combination of textual, oral, and pictorial communication, to promote comprehension and adherence. While pictures have generally proven useful for improving patient comprehension and adherence, not all picture-based interventions have produced successful results. Some icons, particularly clock icons, have been found to be too complex to enhance understanding and could not overcome the advantage provided by the familiarity of the textbased format, suggesting that patients be trained to use pictorial medication information before they are expected to use icons as an aid for medication administration. In addition to enhancing understanding, pictorial aids have been found to improve patients' satisfaction with medication instructions. CONCLUSION: The use of pictorial aids enhances patients' understanding of how they should take their medications, particularly when pictures are used in combination with written or oral instructions.

The iCritical care podcast: a novel medium for critical care communication and education.

Podcasting is a recent creation combining old and new technologies allowing rapid, inexpensive delivery of media content (primarily audio) to the end user, both via the desktop environment and personal media players. The authors' group (the Society of Critical Care Medicine) saw the educational and communication potential for the podcasting concept, and have successfully designed and implemented the first podcast of a national medical society. As of this writing, there are an average of (mean +/- SD) 664 +/- 290 total downloads per podcast, and their podcast feed has been hit over 68,000 times in its first seven months. In this manuscript, the authors provide documentation of their successful endeavor, as well as a structured framework for other organizations to create similar products.
