group of antibiotics represented , 50% of the total quantity of antibiotics used while watch group of antibiotics constituted approximately 50%. Reserve group antibiotics were not prescribed on the day of the survey. Conclusions: Antibiotics are overused among hospitalized patients. There was excessive use of antibiotics in the watch group which are associated with a high risk of antibiotic resistance, and lesser use of the access group antibiotics that have lower risk of resistance in comparison to other countries. Antimicrobial stewardship program that prioritizes reducing antibiotic overuse, reduce the excessive use of watch group antibiotics and promotes assess to reserve group antibiotics when they are needed is recommended.
Objectives: To review publications comparing visual analogue scale data collected using 10 cm scales on paper (pVAS) and scales of various lengths in electronic formats (eVAS). Methods: An informal literature search for evaluation studies was conducted (search terms: "visual analogue scale" and "equivalence" or "validation"). Combined with previously-identified publications, the results and conclusions of these studies were summarised qualitatively. Results: Nineteen published studies were included. All studies were crossover comparisons of paper to at least one form of electronic data collection. Studies varied in size from 12 to 355 subjects (median: 65 subjects) and included general population volunteers and patients suffering from chronic pain, rheumatoid arthritis, psoriatic arthritis, non-small cell lung cancer, and multiple sclerosis. VAS items included measures of pain, fatigue, global health, appetite, anxiety, and alcohol effects. One study was performed in 8 to 10 year olds, the remainder in adults (18 to 86 years). Electronic modes included: PDA (n=8), PC (n=5), smartphone (n=3), tablet (n=3), feature-phone (n=2), and smartwatch (n=1). eVAS length was not reported for 5 studies, and ranged from 2 to 4 cm (n=3, min: 2.1 cm), 4.1 to 6 cm (n=5), 6.1 to 8 cm (n=3), 8.1 to 10 cm (n=2), . 10 cm (n=2, max: 28.9 cm) in the remainder. Authors of all studies concluded pVAS and eVAS were comparable. However, 2 studies reported trends towards higher scores on eVAS vs. pVAS, 3 towards lower scores on eVAS, and 2 studies (Apple Newton and Palm device) indicated eVAS scores may be lower than pVAS at the scale ends. A later study reported no scale-end effects. Differences between eVAS and pVAS were considered not clinically relevant although three publications recommended paper and electronic versions should not be used interchangeably. Conclusions: Published evidence supports the comparability of eVAS and pVAS independent of physical eVAS length.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
