Infection Prevention and Control Training for Healthcare Staff in Ireland

Infection prevention and control (IPC) is the set of everyday practices healthcare staff use to stop germs spreading between patients, residents, visitors and each other. In Irish hospitals, nursing homes, GP practices and home care settings, IPC covers a lot more ground than hand hygiene alone. It includes standard precautions used with every single patient, transmission-based precautions for anyone with a known or suspected infection, correct use of personal protective equipment (PPE), decontamination of shared equipment, and how outbreaks get identified and managed before they spread further. Hand hygiene training for healthcare staff is a core part of that picture, but it is one pillar among several, not the whole structure.

Standard precautions: the baseline for every patient contact

Standard precautions are the minimum practices applied to every patient, every time, regardless of whether an infection has been diagnosed. The logic is simple: you often cannot tell by looking whether someone is carrying an infectious organism, so the same baseline protections apply across the board. According to HSE infection prevention and control guidance published via the Health Protection Surveillance Centre (HPSC), standard precautions include:

• Hand hygiene at the point of care
• Use of PPE selected through a point of care risk assessment
• Respiratory hygiene and cough etiquette
• Safe handling and disposal of sharps
• Environmental cleaning and spills management
• Appropriate handling and disposal of waste and linen
• Aseptic technique for invasive procedures
• Use of single-use equipment where appropriate, and correct reprocessing of reusable equipment and instruments

Hand hygiene sits at the top of that list because it is the single most frequently used and most effective measure on it, but the list only works as a system. Skipping environmental cleaning or reusing equipment without proper reprocessing can undo the benefit of good hand hygiene practice elsewhere on a ward or in a treatment room.

Transmission-based precautions: contact, droplet and airborne

When a patient has a confirmed or suspected infection that standard precautions alone will not reliably contain, staff add transmission-based precautions on top. These are matched to how the specific organism actually spreads, and HSE guidance groups them into three categories.

These categories are not always used in isolation. A patient can be placed on more than one type of precaution at once depending on the organism involved, and the decision is normally made with input from the local infection prevention and control team rather than left to guesswork on the floor.

PPE: choosing it, putting it on, taking it off safely

Which PPE gets used, and when, is meant to follow a point of care risk assessment (PCRA) — a quick judgement made before each episode of care about the task at hand, the patient's condition, and the likely exposure to blood, body fluids or respiratory secretions. HSE's Antimicrobial Resistance and Infection Control (AMRIC) programme promotes PCRA specifically so that PPE use is proportionate: neither skipped when it is needed, nor applied as a blanket habit when it is not.

Sequence matters as much as selection. Most contamination linked to PPE happens during removal rather than while it is being worn, which is why donning and doffing follow a set order rather than whatever feels quickest. As a general principle, PPE goes on before contact with the patient begins and comes off immediately afterwards, starting with the most contaminated item — typically gloves — followed by hand hygiene, then the gown or apron, eye protection and mask or respirator in turn, with hand hygiene repeated again once everything is off. HSE has published a dedicated guide to donning and doffing standard PPE for exactly this reason: getting the order wrong can transfer contamination onto skin, uniforms or the surrounding area. Removing PPE safely often has to happen while also repositioning or supporting a patient, which is one reason PPE competency and manual handling and patient moving training tend to be taught as connected skills rather than isolated modules.

Decontaminating equipment between patients

Decontamination is defined in HSE standards as the combination of cleaning, disinfection and sterilisation used to render reusable invasive medical devices safe for reuse. This is not limited to acute hospitals: HSE Standards for Decontamination cover central decontamination units in hospitals, local decontamination arrangements in general practice, dental and podiatry settings, and equipment that is loaned or shared between services.

Reusable non-invasive equipment — commodes, hoists, blood pressure cuffs, wheelchairs — falls under the same principle even though it is not covered by the same sterilisation standards as invasive devices. It still needs cleaning between patients according to local policy and the manufacturer's instructions. In a busy ward or clinic this is one of the steps most likely to get missed under time pressure, and it is a recurring theme in healthcare-associated infection investigations for that reason.

Managing outbreaks and isolation

When several cases of the same infection appear in a unit or facility close together in time, it is treated as a suspected outbreak and triggers a structured response: isolating or cohorting the affected patients or residents, stepping up cleaning and PPE use, notifying public health, and often restricting new admissions or visiting until the situation is controlled.

Certain diseases carry a legal notification requirement. Under the Infectious Diseases Regulations 1981, as amended (including the 2022 amendment introduced by S.I. No. 252 of 2022), medical practitioners and the clinical directors of diagnostic laboratories must notify the Medical Officer of Health or Director of Public Health when they identify a notifiable disease, generally through the Computerised Infectious Disease Reporting (CIDR) system. The HPSC maintains the full list of notifiable diseases, and some — such as bacterial meningitis or legionellosis — require immediate telephone notification given how quickly they can spread.

Outbreaks tend to hit hardest in settings where residents are older, frailer or medically vulnerable, which is one reason outbreak protocols in nursing homes and disability services sit alongside other resident-protection responsibilities, including safeguarding vulnerable adults training.

Where hand hygiene fits into all of this

None of the above replaces hand hygiene — it sits alongside it. Hand hygiene remains the most frequently performed and most effective single IPC measure, which is exactly why it has its own dedicated training and its own moment at the point of care before and after every patient contact. But treating hand hygiene as the whole of IPC is where gaps tend to open up in practice. A C. difficile outbreak on a ward is not stopped by handwashing alone if contact precautions and equipment decontamination are not also in place at the same time. Full IPC training covers hand hygiene as one required element within all of the areas above, not as a stand-in for them.

Frequently asked questions

What is the difference between standard precautions and transmission-based precautions?

Standard precautions apply to every patient, every time, because infection status is not always known. Transmission-based precautions are added on top of standard precautions for a patient with a confirmed or suspected infection, and are matched to how that specific organism spreads — by contact, droplet or airborne routes.

What PPE is needed for airborne precautions?

Airborne precautions call for a fit-tested FFP2 or FFP3 respirator, along with placement in a single room, ideally with negative-pressure ventilation where the facility has it. This level of protection is used for organisms that can stay suspended in the air and travel further than droplet spread, such as tuberculosis, measles and chickenpox.

Who is legally required to notify a suspected outbreak in Ireland?

Under the Infectious Diseases Regulations 1981, as amended, medical practitioners and the clinical directors of diagnostic laboratories are required to notify the Medical Officer of Health or Director of Public Health when a notifiable disease is identified, usually via the Computerised Infectious Disease Reporting (CIDR) system. The Health Protection Surveillance Centre (HPSC) publishes and maintains the current list of notifiable diseases.

How often should shared equipment be decontaminated?

Reusable equipment should be decontaminated between every patient use, following local policy and the manufacturer's instructions. Invasive medical devices go through a defined cleaning, disinfection and sterilisation process under HSE decontamination standards, while non-invasive shared equipment such as hoists or blood pressure cuffs still needs cleaning between uses even though it falls outside those sterilisation requirements.

Is IPC training mandatory for healthcare staff in Ireland?

Individual employer policies vary, but infection prevention and control is treated as core, ongoing training across the HSE and most healthcare providers, with dedicated e-learning programmes made available to staff through HSeLanD, the HSE's online learning platform. Requirements and refresher intervals are generally set at organisational or role level rather than by a single national rule, so it is worth checking what applies in your own workplace.

IPC is not one skill — it is a set of habits and systems that only work properly when everyone in a building follows them together. Hand hygiene starts the process, standard and transmission-based precautions carry it through direct patient contact, and decontamination and outbreak notification close the loop when something does get through. Seeing how the pieces connect is a useful starting point before looking at any one element, including hand hygiene, in more depth.
