"The patient with confirmed pulmonary tuberculosis was placed on airborne precautions in a single side room with an en-suite facility."

"negative pressure room"

An isolation room in which air pressure is maintained lower than that of the surrounding areas so that potentially contaminated air flows inward rather than outward

"The respiratory unit has four negative pressure rooms reserved for patients requiring airborne isolation."

"protective isolation"

Reverse isolation measures used to shield severely immunocompromised patients from environmental pathogens rather than to prevent transmission from the patient to others

"Bone marrow transplant recipients were nursed in protective isolation with filtered air supply and a strict visitor policy."

"cohort nursing"

The practice of grouping patients infected or colonised with the same organism together in one area, and assigning dedicated staff to care for them, to limit cross-transmission

"sterilisation"

A process that destroys or eliminates all forms of microbial life including spores, typically applied to surgical instruments and implants

"All reusable surgical instruments undergo sterilisation by steam under pressure in the central sterile services department."

"high-level disinfection"

A decontamination process that destroys all vegetative bacteria, mycobacteria, fungi, and viruses, but not necessarily all bacterial spores, used for semi-critical items

"Flexible endoscopes require high-level disinfection between patient uses because they contact mucous membranes."

"thermal disinfection"

The use of heat — typically hot water — to kill microorganisms on equipment, often used in automated washer-disinfectors for bedpans and utensils

"The bedpan washer delivers thermal disinfection by maintaining a temperature of 80°C for one minute during the final rinse cycle."

"chemical disinfectant"

A substance that destroys or inactivates microorganisms on inanimate surfaces, selected according to the spectrum of activity required and the material to be treated

"A chlorine-based chemical disinfectant at 1000 ppm was used to decontaminate the environment after the C. difficile outbreak."

"Spaulding classification"

A system that categorises medical devices into critical, semi-critical, and non-critical items based on the risk of infection associated with their use, guiding the level of decontamination required

"The policy uses the Spaulding classification to determine whether each piece of equipment requires sterilisation, high-level disinfection, or low-level cleaning."

"reprocessing"

The entire multi-step process of cleaning, disinfection or sterilisation, inspection, packaging, and storage required to make a reusable medical device safe for use on another patient

"Failures in endoscope reprocessing were linked to patient-to-patient transmission of infection during outbreaks at several hospitals."

"antimicrobial stewardship"

A coordinated programme to optimise the use of antimicrobials to improve patient outcomes, reduce the risk of adverse effects including resistance, and ensure cost-effective treatment

"The antimicrobial stewardship team reviews all patients on broad-spectrum antibiotics after 72 hours to assess the need for de-escalation."

"antimicrobial resistance"

The ability of microorganisms to resist the effects of antimicrobial agents, making standard treatments less effective and increasing the risk of prolonged illness

"The WHO lists antimicrobial resistance among the greatest threats to global health, food security, and development."

"de-escalation"

The practice of switching from a broad-spectrum antibiotic to a narrower-spectrum agent once the causative organism and its sensitivities are known

"De-escalation from meropenem to amoxicillin-clavulanate was recommended once culture results confirmed a fully sensitive E. coli."

"empirical therapy"

The initiation of antimicrobial treatment based on the most likely causative organisms before laboratory results are available

"antibiogram"

A summary of the susceptibility of bacterial isolates from a given institution or region to various antimicrobial agents, used to guide empirical prescribing decisions

"The microbiology department publishes an updated antibiogram each year to reflect current patterns of resistance in the hospital's patient population."

"minimum inhibitory concentration"

The lowest concentration of an antimicrobial agent that prevents visible growth of a microorganism, used to determine susceptibility or resistance

"The minimum inhibitory concentration result showed the pathogen was resistant to cefuroxime but susceptible to piperacillin-tazobactam."

"formulary restriction"

A policy that limits the prescribing of certain antimicrobials — typically broad-spectrum or reserve agents — to specific clinical indications or requires approval from a specialist

"Carbapenems are subject to formulary restriction and require prior authorisation from the infectious diseases team before dispensing."

"post-prescribing review"

A structured reassessment of an antimicrobial prescription after 48 to 72 hours, using clinical progress and laboratory results to decide whether to continue, change, or stop treatment

"The ward pharmacist conducts a post-prescribing review on all patients started on intravenous antibiotics to support timely IV-to-oral switch."

"outbreak"

The occurrence of cases of an infection in excess of what would normally be expected for a given time period and place, or the occurrence of two or more linked cases

"The IPC team declared an outbreak after three patients on the same ward developed diarrhoea and tested positive for norovirus within 48 hours."

"index case"

The first identified case in a cluster or outbreak, from which subsequent transmission may be traced

"Contact tracing traced the source of the MRSA outbreak back to the index case admitted from a care home the previous month."

"surveillance"

The ongoing, systematic collection, analysis, and interpretation of health data to guide public health action and evaluate the effectiveness of infection prevention measures

"Active surveillance of device-associated infections allowed the ICU to identify a rising trend in central-line infections before it reached outbreak level."

"root cause analysis"

A structured investigation method used to identify the underlying causes of an infection event or outbreak rather than simply addressing its immediate symptoms

"A root cause analysis of the catheter-related bloodstream infection cluster identified gaps in insertion technique training as a key contributing factor."

"contact tracing"

The process of identifying and following up with individuals who may have been exposed to a case of infection, to interrupt further transmission

"Public health officials conducted contact tracing after a patient with active tuberculosis was found to have attended the outpatient clinic on multiple occasions."

"incubation period"

The time between exposure to an infectious agent and the onset of symptoms, important for determining the likely source and timing of transmission

"Because the incubation period for norovirus is 12 to 48 hours, the team focused the investigation on what patients ate and whom they contacted on the day before symptoms began."

"point prevalence survey"

A one-day snapshot of the prevalence of healthcare-associated infections and antimicrobial use across an institution or group of institutions, repeated periodically to track trends

"The national point prevalence survey found that 6.4% of inpatients had a healthcare-associated infection on the survey day."

"infection prevention and control link practitioner"

A ward-based or departmental healthcare worker trained to support and champion infection prevention activities as part of their normal role alongside specialist IPC professionals
