Description

From the listing uploaded by “appupdater”.

The IMPACT Guideline serves as an invaluable reference tool for medical and health professionals in reinforcing the appropriate use of antimicrobial drugs. Antimicrobial resistance has reached alarming levels. IMPACT Guideline recognises the dangers of antimicrobial resistance, the tremendous adverse effect it has on quality medical care, and the need for a strong, coordinated and multifaceted response. The IMPACT Guideline combines the latest scientific evidence on the usage of antimicrobial agents, empirical therapy of common infections, treatment of infections with known pathogens and surgical prophylaxis with data on the prevalence and sensitivity patterns of different pathogens in Hong Kong. It also contains practical tips on the safe use of antibiotics in inpatient settings, management of penicillin allergy and application of diagnostic tests on clinical microbiology. Disclaimer: The IMPACT Guideline app is intended for medical professionals as a reference only and is not intended to be prescriptive or a substitute for clinical judgment in the management of individual patients. It is not a complete or authoritative diagnostic or treatment guide. Medical professionals are encouraged to obtain relevant information from other sources, including the latest drug alerts, and exercise their clinical judgment.
