[Online information for relatives of critically ill patients : Pilot test of the usability of an ICU families website]. / Onlineinformation für Angehörige von kritisch Kranken : Pilottestung zur Nutzbarkeit der ICU Families Website.

BACKGROUND: Relatives of intensive care patients have a very high need for information. This is due to the acute and serious, often life-threatening illness of the patients and the very complex and technical environment of an intensive care unit (ICU). Unmet needs for information can increase anxiety, sleep disorders, stress, and depressive symptoms in the relatives. OBJECTIVES: The potential of the ICU families website in terms of usability and functionality during real-time testing were evaluated. METHODS: The ICU families project created a dynamic online information platform in the form of a password-protected website. It contains pictures, written explanations, 5 movies, a forum and a diary function. The usability of the website was tested among 10 lay people and 10 experts (7 nurses and 3 physicians) according to the Think Aloud Method. RESULTS: The outcome is qualitative feedback based on video documentation by laypeople and suggestions by experts. Criticisms mentioned by the test subjects were insufficient image material, small size of the operator contact link and lack of a home button. With a mean of 9.1 (rating scale, 0 = very poor, 10 = very good), the website was almost universally recommended by the experts. CONCLUSIONS: This usability test of a website for relatives of ICU patients conducted among 20 test subjects showed the biggest challenges related to solving individual test scenarios and provided valuable hints for improving website usability. Features of the website highlighted as positive were the clear layout, the symbols, the diary and the consideration of children. This information was used to improve the site for subsequent roll-out in a randomized, controlled and multicentre study.

Comparison of abbreviation usage practices in two Philippine tertiary hospitals and perceived effects on medical training

OBJECTIVES:To (1) compare abbreviation usage practices in the Doctors' Orders and History Sheet in two tertiary hospitals in Cebu City, namely, Cebu Velez General Hospital (CVGH) and Vicente Sotto Memorial Medical Center (VSMMC); (2) determine why medical students and physicians use abbreviations and (3) determine the perceived effects on medical student training. METHODS:This is a descriptive cross-sectional study utilizing medical chart reviews as well as group and key informant interviews. Stratified Random Sampling with Proportionate Allocation was used to select 100 charts each from CVGH and VSMMC. Purposive sampling was done for key informants. RESULTS: All patients' clinical history, physical examination and doctors' orders in all departments of both hospitals contained abbreviations. First initialization was the most common form, e.g. BP (blood pressure). Non-universally-accepted abbreviations were common, e.g. HFD (heredofamilial disease). Potentially dangerous abbreviations were noted, e.g. d/c, D/C. Abbreviations were used to maintain patient-doctor confidentiality, save space and time, and for convenience. Perceived effects on medical training included speeding up of task performance. CONCLUSIONS: Use of abbreviations in medical charts among medical students and physicians in both private and public tertiary hospitals in the Philippines is a prevalent practice. While such has its perceived benefits, it also poses potential danger to patients because not all abbreviations are understood and used the same way. Medical schools and their training hospitals must initiate moves to standardize the use of abbreviations in medical education and promote awareness of their potential dangers. The authors suggest that potential dangers/benefits of abbreviations be formally introduced in medical school as a separate topic.
