The prophylactic use of antimicrobial agents to prevent infections in non-surgical situations has hardly been investigated, according to Deelen, et al. (2017), who investigated the extent, indications and appropriateness of antimicrobial prophylaxis given outside the operating room in a tertiary-care hospital.
Four point-prevalence surveys were conducted in which all inpatients on that day were screened for the use of prophylactic antimicrobials: medical prophylaxis, prophylaxis around non-surgical interventions and surgical prophylaxis given on the ward. The primary endpoint was the extent of prophylaxis relative to the total number of antimicrobial prescriptions. We also investigated per prescription the presence of a (local) protocol and adherence to these protocols.
The researchers registered a total of 1,020 antimicrobial prescriptions, of which 317 (31.1%) were given as prophylaxis. 827/1020 were antibiotic prescriptions. Of these antibiotic prescriptions, 17.0% was medical prophylaxis, 2.7% prophylaxis around non-surgical interventions and 6.9% surgical prophylaxis administered on a ward. For medical antibiotic prophylaxis, a protocol was present in 125 of 141 prescriptions (88.7%); the protocol was followed in 118 cases (94.4%). For prophylaxis around non-surgical interventions and surgical prophylaxis on the wards, protocol presence and adherence rates were 59.1% and 92.3%, and 73.3% and 97.6% respectively. Of the 96 antiviral and 97 antifungal prescriptions, 42.7% and 57.8%, respectively, were medical prophylaxis, of which 95.1 and 96.3% were prescribed according to protocols respectively.
The study's authors concluded that antimicrobial prophylaxis outside the operating theatre is responsible for a considerable part of total in-hospital antimicrobial use. For most prescriptions there was a protocol and adherence to the protocols was high. The main targets for improvement were prophylaxis around non-surgical interventions and surgical prophylaxis given on the ward.

How Contaminated Is Your Stretcher? The Hidden Risks on Hospital Wheels
July 3rd 2025Despite routine disinfection, hospital surfaces, such as stretchers, remain reservoirs for harmful microbes, according to several recent studies. From high-touch areas to damaged mattresses and the effectiveness of antimicrobial coatings, researchers continue to uncover persistent risks in environmental hygiene, highlighting the critical need for innovative, continuous disinfection strategies in health care settings.
Beyond the Surface: Rethinking Environmental Hygiene Validation at Exchange25
June 30th 2025Environmental hygiene is about more than just shiny surfaces. At Exchange25, infection prevention experts urged the field to look deeper, rethink blame, and validate cleaning efforts across the entire care environment, not just EVS tasks.
A Controversial Reboot: New Vaccine Panel Faces Scrutiny, Support, and Sharp Divides
June 26th 2025As the newly appointed Advisory Committee on Immunization Practices (ACIP) met for the first time under sweeping changes by HHS Secretary Robert F. Kennedy Jr, the national spotlight turned to the panel’s legitimacy, vaccine guidance, and whether science or ideology would steer public health policy in a polarized era.
