Hygienic hand disinfection according to RKI: indications, obligations and evidence

Hygienic hand disinfection is, according to the RKI/KRINKO recommendation on hand hygiene in healthcare facilities (Bundesgesundheitsblatt 2016, with subsequent updates), the most important individual measure for the prevention of nosocomial infections. Section 23 IfSG obliges hospitals and comparable institutions to take into account the recommendations of the Commission for Hospital Hygiene and Infection Prevention (KRINKO). In the supervisory practice of the health authorities, this consideration is treated as a de facto commitment. Anyone who deviates without a valid reason bears the burden of justification and proof in the event of damage. Inspection protocols from the past 24 months show that it is not the disinfectant that is being criticized, but rather the lack of compliance monitoring and the incomplete proof of training.

This article describes the five indications defined by WHO and RKI, the required compliance quotas per station and professional group, the documentation obligations of the hygiene officer and the hygiene specialist as well as the interfaces to the Medical Device Operator Ordinance, the Biological Substances Ordinance and the IfSG reporting paths. You will also learn how the CIVAC compliance platform and officer-as-a-service constellation combine compliance monitoring, proof of training, consumption figures and the hygiene officer's appointment certificate in a uniform workflow, so that proof is available without any search effort following an inspection by the health authority or as part of a KTQ certification. There are 490 audit templates, a versioned reporting line and EU data residency running in the background.

The legal anchoring of hygienic hand disinfection runs on three levels. First level: Section 23 (3) IfSG obliges heads of hospitals and facilities for outpatient surgery, prevention or rehabilitation facilities, dialysis facilities and day clinics to ensure that the measures necessary according to the state of medical science are taken to prevent nosocomial infections and to avoid the further spread of pathogens. This state-of-the-science clause refers to the KRINKO recommendations.

Second level: Section 23 (4) IfSG obliges the continuous recording and assessment of nosocomial infections and developments of resistance. According to the prevailing interpretation, this obligation to record also includes the hand hygiene compliance indicators because without their documentation, an appropriate assessment of the infection rate is not possible. Third: The state hygiene regulations (e.g. MedHygV NRW, BayMedHygV, HambKHygVO) specify the obligations to appoint a hygiene officer and to provide regular training.

Anyone who does not implement the KRINKO recommendation on hand hygiene without providing evidence of deviating measures that are equally effective risks a complaint from the responsible health authority. Repeated complaints can lead to the activity being banned in accordance with Section 17 IfSG. The role of the hygiene officer is therefore not an optional staff function, but rather a supervisory role explicitly anchored by the legislature. CIVAC anchors the appointment certificate and the ongoing reporting line in a uniform platform. The appointment certificate, signed, filed, verifiable. Audit-proof, documented, Section 23-proof. In addition: During inspections, the responsible supervisor expects a current hygiene plan countersigned by management, which shows hygienic hand disinfection as a separate chapter with indications, means, exposure times and observation frequency and can be found immediately in the electronic file. The obligation to update applies at least annually, whenever the product range changes or new scientific KRINKO recommendations are made.

The WHO and the RKI have defined five indications for hygienic hand disinfection, which are internationally standardised as 5 Moments of Hand Hygiene. These five moments are: firstly before patient contact, secondly before aseptic activities, thirdly after contact with potentially infectious material, fourthly after patient contact, fifthly after contact with the immediate patient environment. Each of these indications must be shown separately in training materials, observation forms and audit templates because compliance regularly varies significantly for each indication.

Hygienic hand disinfection is carried out with an alcohol-based hand disinfectant from the VAH list or an equivalent listed list. According to KRINKO recommendations, the exposure time is at least 30 seconds; for MRSA patients and suspected norovirus, extended exposure times of 60 to 90 seconds are relevant according to the manufacturer's instructions. The amount must be sufficient to keep both hands moist throughout the entire exposure time, usually 3 to 5 ml.

Before hygienic hand disinfection, jewelry and watches must be removed from the hands and forearms and fingernails must be short and unpainted. Artificial nails or gel nails are not permitted. Washing your hands with soap and water is not a substitute, but rather a supplement to visible contamination or after exposure to spores (Clostridioides difficile). The CIVAC audit templates contain standardised observation forms for each indication, so that the hygienist can systematically count per station and shift without having to maintain their own recording form. The sheets are compatible with the data structures of the Clean Hands Campaign and export directly to the KISS surveillance of the National Reference Centre for Surveillance of Nosocomial Infections. A few observation periods of 15 to 20 minutes per shift are sufficient in a representative distribution in order to obtain statistically reliable rates, provided that the observer qualifications are documented and the initial interview and debriefing are recorded in the reporting line.

The compliance rate for hygienic hand disinfection is the central control instrument for hospital hygiene. It is calculated as a quotient of hand disinfections carried out and overall indications and is shown for each indication, professional group, ward and shift. The RKI and the Clean Hands Campaign are based on a compliance rate of over 80 percent as a target value; individual KRINKO-relevant areas (intensive care, neonatology, oncology) are typically higher, general medical areas are often lower.

The measurement is carried out through direct observation in representative samples. At least 200 indications per station are recommended per quarter, divided into day and night shifts. Observation must be carried out by trained observers who are themselves required to undergo hygiene training. Covert or open observation is methodically justified in each case. In addition to direct observation, the consumption of hand disinfectant per day of patient occupancy (HD consumption in ml per patient day) is recorded as an indirect indicator.

Both measurement methods are included in the recording in accordance with Section 23 Paragraph 4 IfSG and are shown in the hospital's hygiene report. Since 2008, the Clean Hands Campaign has been awarding certificates in bronze, silver and gold depending on the compliance level and structural features. Anyone who uses this certificate must maintain the underlying data permanently. CIVAC collects observation data, consumption metrics and certification status in a single hygiene reporting line and makes them available to the health department, KTQ audits and management in consistent reporting formats. The auditor calls, the evidence is ready. In addition, outlier stations are automatically marked so that the hygiene commission takes targeted action and does not have to wait for the next quarterly report. The clock starts on awareness.

The KRINKO recommendation on personnel and organisational requirements for the prevention of nosocomial infections differentiates between the hospital hygienist, the hygiene officer, the doctor and the hygiene specialist. All three roles are relevant for hygienic hand disinfection, each with a different focus. The hospital hygienist (specialist in hygiene and environmental medicine or specialist with additional training in hospital hygiene) is responsible for the strategic orientation and the hygiene plan concept.

The hygiene representative doctor is to be appointed for each clinic or functional area and takes over the professional interface between the hygiene department and the department's medical service. The hygiene specialist (HFK, three-year further training according to DKG recommendations) carries out the operational inspection, training and compliance monitoring. Your tasks include the training of new employees, the ongoing updating of the hygiene plan, the investigation of clusters of nosocomial infections and reporting to the hygiene commission.

KRINKO recommends a reference value of one HFK per 100 beds for each hygiene specialist in acute care, and even narrower in the intensive care area. These keys must be documented in the hygiene plan and presented during inspections. The appointment certificate for the hygiene officer doctor and the hygiene specialist must be current, dated and signed by the management. CIVAC bundles appointment certificates, proof of qualifications and ongoing training documentation into a searchable reporting line. The appointment certificate, signed, filed, verifiable. Others run compliance like a filing cabinet. We run it like software. Licence the workspace for your internal representatives, or have our representatives order it. Anyone who employs an external hygiene representative, a doctor, must also specify availability, replacement arrangements and start date so that in the event of an increase in cases, the escalation chain is in place without delay. If there are several locations, each location has its own responsible person with a local reporting line, linked to the relevant state hygiene regulations of the federal state.

The KRINKO hand hygiene recommendation requires regular training for all employees with patient contact, including doctors, nursing staff, therapists, cleaning staff and student assistants. Initial training in onboarding, followed by at least an annual refresher. Event-related training follows in the event of outbreaks, the introduction of new products or structural abnormalities in compliance monitoring. The obligation falls on the owner of the facility, the implementation is carried out by the hygiene specialist or the hygiene representative doctor.

Mandatory content of a hand hygiene training course includes: firstly, the five indications with case studies from the own department, secondly, the correct technique according to EN 1500 (six movement steps over 30 seconds), thirdly the selection and application of the hand disinfectant used including exposure time, fourthly the use of skin protection and care to avoid it work-related skin diseases, fifthly, the importance of not wearing jewelry and nail care, sixthly, the distinction between hygienic and surgical hand disinfection as well as the additional measures for MRSA, ESBL, VRE, Norovirus and Clostridioides difficile.

The training certificate contains the elements required in every compliance system: table of contents with version, list of participants with function, date, duration, learning success control, qualification of the trainer. The clock starts on awareness. CIVAC connects the training module with the directory of processing activities and with the ISO/IEC 27001:2022 control landscape, as far as patient data is processed electronically. This creates a continuous evidence path from training to observation to the reporting obligation in accordance with Section 23 IfSG. External cleaning service providers and food providers must be included in the same training matrix because their employees can touch patient environments and thus trigger an indication for hygienic hand disinfection themselves. Training languages ​​other than German must be listed explicitly so that the content is reliably understood.

Inspection reports from German health authorities show recurring patterns of complaints regarding hygienic hand disinfection. First: Compliance monitoring is not carried out systematically, but only sporadically and without a documented sample size. An evaluation of the quota is then not possible. Secondly: consumption figures are not recorded or only summarized for the entire hospital, not on a ward basis. It is then impossible to identify conspicuous areas.

Third: proof of training is incomplete or completely missing, especially for cleaning staff from external service providers, on-call doctors and student assistants. These groups are often overlooked in hygiene training, but they are just as subject to training as the core workforce. Fourth: The appointment certificates of the hygiene officer doctor or the hygiene specialist are outdated, not countersigned by the current management or are missing for areas in which they would be required according to the state hygiene regulations.

Fifth: The hygiene plan is not up to date or does not reflect the disinfectants actually used. Sixth: There is a lack of a documented outbreak management process with clear responsibilities, reporting channels to the health authority in accordance with Section 6 (3) IfSG and follow-up. Seventh: The Hygiene Commission meets too rarely or its minutes are incomplete. CIVAC addresses all seven points with templates, reminder logic and the connection to quality management. Audit-proof, documented, Section 23-proof. This means there is no longer any need to search before an announced or unannounced inspection. Eighth and equally common point: inspection logs from previous years are not systematically tracked, so the same complaint occurs again. CIVAC records the measures from each inspection log as closed or open with a due date, linked to the appointment certificate of the person responsible, so that resubmission and escalation take effect systematically instead of being carried out by personal reminders from individual employees.

Hand disinfection is at the intersection of several legal regimes. First: Section 23 IfSG requires the ongoing recording and assessment of nosocomial infections, including resistance levels. This indirectly results in the obligation to record compliance data. Secondly: The Medical Device Operators Ordinance (MPBetreibV) regulates the operation of dispensers, pumps and processing devices that are relevant to hygiene. Dispensers for alcohol-based hand disinfectants count as medical products and must be managed accordingly.

Third: The Biological Substances Ordinance (BioStoffV) and TRBA 250 (Biological Agents in the Health Care System) oblige the employer to provide suitable protective equipment, training and risk assessment. Hygienic hand disinfection is a protective measure in terms of occupational safety for employees and at the same time an infection protection measure for patients. This dual function makes integrated documentation all the more important.

Fourth: Section 6 IfSG requires certain infectious diseases and pathogens to be reported to the responsible health authority. Section 6 (3) IfSG extends the reporting requirement to clusters of nosocomial infections where an epidemic connection is likely. Deadline begins as soon as we become aware of it. The reporting channels must be documented and anchored in the hygiene plan. CIVAC combines hand hygiene compliance with outbreak management and the IfSG reporting path, so that in the event of an outbreak, the hygiene officer, the doctor, the hygiene specialist, the medical management and the management are informed in a uniform reporting line and the report to the health department is clearly documented. In the event of an accumulation of multi-resistant pathogens, the requirements from TRBA 250 for protective equipment also apply, which must be listed separately in the hygiene plan and in the risk assessment. If electronic patient files are affected, GDPR reporting obligations in accordance with Articles 33 and 34 are added, which run in a separate reporting path alongside Section 6 IfSG.

How much effort does proper hand hygiene compliance require? One hygiene specialist per 100 acute beds is a realistic basic value. For compliance observation, at least 200 indications must be directly observed per station and quarter, which corresponds to around 4,000 observations per quarter for 20 stations. Experience has shown that two to three minutes, including documentation, should be allocated per observation, extrapolating one to two full working days per week for observation in a medium-sized hospital alone.

The material costs for alcohol-based hand disinfectants are around 7 to 12 ml per day of patient occupancy in the normal ward area and 60 to 120 ml in the intensive care area. Anyone who is significantly lower than this has a compliance problem. If it is significantly higher, you should examine waste or stockpiling as causes. Consumption is measured for each ward and evaluated together with patient occupancy. This key figure is shown in the annual hygiene report and compared with comparative values ​​from the KISS surveillance (NRZ hospital infection surveillance system).

The actual cost driver is not the observation itself, but the loss caused by an avoidable outbreak. A single MRSA outbreak with bed closures, cleaning, isolation and reporting requirements can cause six-figure follow-up costs, plus reputational damage. CIVAC bundles observation, consumption, training and appointment certificates in the compliance platform and makes Officer-as-a-Service available as an ordering option. In the workspace model, you bear the responsibility yourself; in the officer model, we provide the external hygiene representative, doctor or external hygiene specialist. Licence the workspace for your internal representatives, or have our representatives order it. CIVAC SLA: two business days for the initial setup instead of the classic two to six weeks. The auditor calls, the evidence is ready. The cost structure is shown for each location and number of beds and is clearly documented for management as part of the annual report to the Hygiene Commission.

An effective hand hygiene program begins with an assessment. Which wards, which patient clientele, which professional groups? What compliance rate results from the last three quarters of direct observation? What consumption per day of patient occupancy is recorded for each ward? Which outbreaks or clusters have been reported and processed in the last 24 months? Which training courses were documented in which version and with what learning outcome? This location determination leads to a roadmap with clear priorities for each station.

In the second step, the program is converted into an audit-proof process. These include observation plans with sample size and observer qualifications, monthly consumption data, proof of training per employee, a documented outbreak management process with an IfSG reporting path and a hygiene commission that meets quarterly with a requirement to keep records. In the third step, the program is linked to the requirements of KTQ certification, DIN EN 15224 (quality management in healthcare) and the state hygiene regulations.

CIVAC provides ready-made modules for each of these steps: 490 audit templates, appointment certificates with versioning, training module with learning success control and a reporting line that can be exported directly for health authorities and KTQ visitors. The platform works in two modes: licence the workspace for your internal representatives, or have our officers appointed it. In both models, the CIVAC SLA of two business days applies to the initial setup and EU data residency for all data.

Turn reading into a mandate. Write to info@civac.de or use the contact form on civac.de/faq. We will send a concrete proposal within two working days, tailored to the level of care, number of beds and the responsible health authority, including a gap analysis for KRINKO and Section 23 IfSG as well as a proposal for a sensible distribution of responsibility between the internal hygiene specialist and the external hygiene representative doctor.
