RKI guidelines for hospital hygiene: Implement KRINKO recommendations in a legally secure manner

The recommendations of the Commission for Hospital Hygiene and Infection Prevention (KRINKO) at the Robert Koch Institute represent the actual state of medical science in accordance with Section 23 Paragraph 3 IfSG. Anyone who works in clinics, medical care centres, outpatient surgery centres or inpatient care facilities must be familiar with these recommendations, incorporate them into a hygiene plan and be able to document compliance with them. Case law regularly sees KRINKO recommendations as a standard of care, which requires deviations to be justified and triggers noticeable consequences on the burden of proof in civil law proceedings. Supervisory authorities, medical services and health insurance companies also use the recommendations as an examination grid for inspections and structural inspections.

This guide classifies the most important KRINKO recommendations, the IfSG environment and the tasks of the hygiene officer. It shows how the requirements for hand hygiene, surface disinfection, processing of medical devices, surveillance according to Section 23 Paragraph 4 IfSG and dealing with multi-resistant pathogens can be translated into an audit-proof clinic operation. You will find out which documents must be available, which training frequencies are standard practice and how the hygiene officer's appointment document fits into a consistent reporting line to management. At the end there is a checklist with the typical mandatory evidence that is actually required in a hygiene inspection, as well as a clear path to the platform solution in the CIVAC workspace. The article is aimed at management, medical management, nursing management and hygiene officers themselves who want to set up or reorganize their function in a structured manner.

The legal framework for hospital hygiene in Germany is formed by the Infection Protection Act (IfSG), the state medical hygiene regulations and the recommendations of KRINKO at the Robert Koch Institute. Section 23 IfSG obliges managers of medical care facilities to continuously record nosocomial infections and the occurrence of multi-resistant pathogens and to ensure that the state of medical science is adhered to. Section 23 Paragraph 3 Sentence 2 IfSG expressly highlights KRINKO recommendations as a relevant reference point without making them a formal legal norm. In practice, this special position means that deviations remain justifiable, but are only valid if they are documented in writing and argued at an equivalent level.

The state medical hygiene regulations, such as MedHygV NRW, BayHygV or the Baden-Württemberg Hospital Infection Prevention Ordinance, specify the obligations of the hygiene commission, hygiene officers, hygiene specialists and ABS (Antibiotic Stewardship) structures. They also define training, ordering and reporting requirements. The legal effect is clear: anyone who deviates from a current KRINKO recommendation without a comprehensible justification loses the presumption of lege artis in damages or supervisory proceedings. Hygiene inspections by health authorities in accordance with Section 16 IfSG use the KRINKO recommendations as an examination grid. CIVAC acts here as a compliance platform and officer-as-a-service and maps the requirements of all three levels in a structured workspace, with assignment to specific documents, responsible persons and deadlines. An overview of the role can be found on the page for the hygiene officer. Licence the workspace for your internal representatives or have our representatives appointed, depending on the maturity of your facility. This means that the requirements from IfSG, KRINKO and state regulations are mapped in a consistent documentation structure, instead of in parallel Excel and Word islands.

KRINKO publishes its recommendations in the Federal Health Gazette. For practice, there are six blocks of recommendations that every medical facility should keep as a minimum library and incorporate into the hygiene plan. Firstly, the recommendation on hand hygiene in healthcare facilities, which establishes five indications from the World Health Organisation as a binding structure and prescribes compliance measurements. Secondly, the recommendation on hygiene requirements when reprocessing medical devices in conjunction with Section 8 of the Medical Device Operator Ordinance (MPBetreibV), which requires validation, routine controls and periodic revalidation in accordance with DIN EN ISO 15883. Thirdly, the recommendation on hygiene requirements when cleaning and disinfecting surfaces, which categorizes risk areas and derives cleaning frequencies.

Fourthly, the recommendations on surveillance and hygiene management for multi-resistant pathogens, in particular MRSA, VRE, MRGN and Clostridioides difficile, with risk-adapted screening and isolation regimes. Fifthly, the recommendation on the personnel and organisational requirements for the prevention of nosocomial infections, which defines the minimum staffing ratio for hygiene specialists per number of beds and describes the structures of a hygiene commission. Sixth, specialist recommendations, for example on hygiene during operations, requirements for intensive care units or the prevention of catheter-associated infections. The recommendations are updated regularly. Hygiene officers should carry out documented monitoring of the amendments, as each new version shifts the standard of care and immediately triggers the need for adjustments to the hygiene plan. Others run compliance like a filing cabinet. We run it like software. In the CIVAC library, the current KRINKO recommendations are linked to the version status and assignment to the 490 ready-to-use audit templates, so that updates automatically trigger tasks. Hygiene officers can see at a glance which internal standard operating procedures need to be checked after an amendment, without having to maintain several document lists in parallel.

The appointment of a hygiene officer results from the state medical hygiene regulations in conjunction with Section 23 Paragraph 8 IfSG. Hospitals appoint medical hygiene officers for each department as well as a central hospital hygienist. In care facilities, outpatient surgery centres and MVZs, hygiene-commissioned nurses or doctors must be appointed. The qualification requirements are defined in the respective KRINKO recommendations and state regulations and include at least a 40-hour basic qualification plus annual training with documented proof of hours. Hospital hygienists have significantly more extensive specialist or equivalent qualifications in accordance with the requirements of the KRINKO recommendation on personnel requirements.

The tasks go beyond purely technical advice. Hygiene officers create and maintain the hygiene plan, coordinate training, forward surveillance data to the responsible committees, check purchases for hygiene relevance, advise on construction and renovation measures and are the central contact persons for inspections by health authorities or medical services. In addition, there is participation in the Hygiene Commission, reporting to the management and cooperation with the Medicines Commission as part of Antibiotic Stewardship. The appointment is made in writing by the facility management with a clearly defined scope of tasks, reporting line and exemption percentage, which is between 0.1 and 0.5 full-time equivalents, depending on the size of the facility. The appointment certificate, signed, filed, verifiable. At CIVAC, the appointment certificate is stored in version form in the workspace, with automatic reminders of training deadlines, reappointments and changes in management. On the page for the Hygiene Officer, the standard duties, training intervals and contract components are presented in detail, including the interface to data protection and occupational safety. Anyone who fills the role can initiate the onboarding path within 2 working days instead of having to expect classic mandate waiting times of 2 to 6 weeks.

The hygiene plan is the central control document according to Section 23 Paragraph 5 IfSG. It must be in writing, updated regularly and accessible to all employees, including temporary employees, freelancers and external service providers. In terms of content, it includes at least twelve chapters: hand hygiene, staff clothing and protective equipment, surface cleaning and disinfection, processing of medical devices, laundry hygiene, waste disposal, food hygiene, water hygiene, dealing with multi-resistant pathogens, isolation measures, surveillance and training concept. There are also appendices with specific standard operating procedures for each department and risk area, such as the operating room, intensive care unit, endoscopy, oncology or obstetrics.

The evidentiary value of the hygiene plan depends on its timeliness and comprehensible versioning. In liability proceedings, it is regularly checked whether the hygiene plan that was valid in the event of damage corresponded to the KRINKO recommendations at the time. Outdated versions without adaptation to current recommendations shift the burden of presentation and proof to the institution's expense and can lead to coverage being rejected in insurance matters. Updates must be carried out at least annually, and immediately if necessary in the event of new KRINKO recommendations, new pathogen conditions or changes in the structural situation. In the CIVAC workspace, each version of the hygiene plan is archived with a time stamp, releaser and cross-reference to the underlying KRINKO recommendation. The following applies: the examiner calls, the proof is ready. Evidence of training on the content of the hygiene plan is documented in parallel in the personnel file module in an audit-proof manner, with a link to the area of ​​activity, risk classification and training type. This makes it possible to prove that employees have taken note of the current hygiene plan before starting their work and on an annual basis, which is often the crucial detail in liability proceedings. The evidentiary value does not decrease as soon as employees leave because the training log versioning is retained. External service providers, such as cleaning staff, laundry or food supply, are also managed in the same module so that the training landscape is complete.

Section 23 Paragraph 4 IfSG obliges certain institutions to continuously record nosocomial infections and the occurrence of multi-resistant pathogens. The records must be kept for ten years and presented to the health authority upon request. Section 4 Paragraph 2 No. 2 Letter b IfSG regulates which indicator infections and indicator pathogens must be recorded through specifications from the Robert Koch Institute. The essential modules are ITS-KISS for intensive care units, OP-KISS for postoperative wound infections, HAND-KISS for hand hygiene compliance and MRSA-KISS for surveillance of multi-resistant pathogens. Which modules must be included depends on the range of care provided by the facility and the additional state requirements.

The obligation to record is more than a compulsory statistical exercise. It is the basis for internal assessments, action plans and reports to the Hygiene Commission. If accumulations are detected, measures must be taken immediately and documented. Section 6 (3) IfSG also stipulates an obligation to report two or more nosocomial infections with a probable epidemic connection. Deadline begins as soon as we become aware of it. In the CIVAC workspace, surveillance is carried out in a structured module with pathogen registers, case histories, cluster alarms and automatic reporting paths to the health department. The evaluations are reported quarterly to the hygiene commission and management, with a clear link between findings, measures and effectiveness control. This means that institutions fulfil both the recording and assessment obligations in an audit-proof workflow and reduce the risk that gaps in the surveillance evaluation are criticized in the inspection report. The connection to KISS modules is prepared via structured data fields so that external evaluations do not have to be laboriously compiled every quarter. In the event of inquiries from authorities, the ten-year archive volume can be narrowed down immediately and handed over without media disruption, which significantly shortens inspection times.

Training is one of the most common weak points in hygiene inspections. The KRINKO recommendations and state regulations require at least annual training for all patient-related employees, with documented content, participation lists and learning success monitoring. Special training obligations with timesheets and topic rotation apply to hygiene specialists and hygiene officers. Anyone who carries out training without comprehensible documentation loses the evidentiary value. In the event of damage, a mere attendance list is usually not enough; verifiable proof of learning success and a clear reference to the respective hygiene plan chapter are required.

Compliance measurements are a second mandatory field. Hand hygiene compliance is collected through direct observation or electronic measurement systems and reported to HAND-KISS, with clearly defined sample sizes and observation periods. Preparation processes are documented using validated procedures with routine controls and periodic revalidation in accordance with DIN EN ISO 15883. Surface disinfection is checked through inspections, proof of funds, concentration tests and random checks. In CIVAC's audit module, all of these documents run against a uniform audit grid made up of 490 ready-to-use audit templates. Results are linked to measures, those responsible and effectiveness monitoring. Others run compliance like a filing cabinet. We run it like software. Audits by health authorities, medical services, health insurance companies or certification bodies can be prepared within a few hours. A collection of the typical test grids can be found in the CIVAC FAQ, including the most common defects in inspections and the associated catalogue of measures. The Hygiene Commission receives its meeting report directly from the workspace, with linked documents instead of isolated Excel evaluations, which reduces the length of the meeting and increases the traceability of the decisions. Effectiveness checks are tracked in the same workflow, so that completed measures can be clearly distinguished from open points and management can see the level of maturity at all times.

According to KRINKO, MRE management is an independent mandatory component. The recommendations on MRSA, MRGN, VRE and Clostridioides difficile require risk-adapted screening strategies, hygiene measures in the event of proven colonization, documented isolation regimes and cross-sector information transfer in accordance with Section 23 Paragraph 8 IfSG. When transferring or discharging colonized or infected patients, the subsequent facility must be informed in advance. Violation of this information obligation is regularly relevant to liability and can lead directly to conditions in supervisory audits. The handling of outpatient and inpatient readmissions also requires clear regulations.

Risk areas are in particular intensive care units, hematology-oncology, premature baby wards, departments requiring dialysis and high-risk surgical areas. Here, KRINKO requires surveillance data with higher granularity as well as additional protective measures, such as extended isolation, dedicated care teams and separate processing routes for devices close to the patient. Personnel-related measures such as check-ups, employment bans in accordance with Section 31 IfSG in the event of proven pathogen carriage and quarantine orders in accordance with Section 30 IfSG must be regulated in a defined procedure. In the CIVAC workspace, MRE cases are managed as protected cases, with a need-to-know role and rights concept, links to surveillance data and automatic escalation in the event of clusters. This allows installation information, hygiene measures, training requirements and supervisory reports to be bundled in a consistent workflow. The Role overview shows how the hygiene officer is interlinked with data protection, ISMS and occupational safety, since MRE data also represent special categories according to Art. 9 GDPR and require special security measures. Anyone who ignores these interfaces risks parallel data protection violations alongside the actual hygiene incident, which supervisory authorities are increasingly examining together. The integrated view from IfSG, GDPR and occupational safety also avoids the typical frictional losses between the hygiene department, data protection and IT security, which cause many delays in practice.

During hygiene inspections by the health department in accordance with Section 16 IfSG or audits by the medical service, deficiencies emerge in a recurring pattern that every facility management should be aware of. Firstly, there is a lack of updated hygiene plans that take the latest KRINKO amendments into account, including comprehensible version documentation. Secondly, training certificates are incomplete or show gaps for temporary employees, freelance workers and external service providers. Thirdly, the written appointment of the hygiene officer is missing or the appointment documents are out of date, for example after a change in management. Fourthly, surveillance data are not systematically evaluated or are not regularly reported to the hygiene commission and management.

Fifthly, the reprocessing of medical devices shows gaps in validation and routine control according to Section 8 MPBetreibV, especially in decentralized reprocessing units in operating theaters or endoscopy areas. Sixth, the MRE information transfer during transfers is incomplete, for example in the case of short-term transfers on the weekend. Seventh, there is a lack of regular training for cleaning staff and external service providers, whose activities must be included in the hygiene plan. Eighthly, the hygiene commission is not convened regularly or without minutes, so that there are no comprehensible decisions. Structured preparation with 490 ready-to-use audit templates, checklists for the defects mentioned and central document management significantly reduces the risk of complaints. In the CIVAC workspace, these points are created as compulsory modules, with appointments and who is responsible. If you have to prepare for an inspection two working days in advance, you can only do this with a consistent document structure, not with distributed Excel files. Audit-proof, documented, § 23 IfSG-proof. In addition, a quarterly internal pre-inspection helps, in which the hygiene officer systematically checks the typical deficiencies and submits measures with a deadline before the external inspection actually takes place.

Operational experience shows that hospital hygiene only remains audit-proof if the hygiene plan, training, surveillance, MRE management and auditing are managed in an integrated platform. Distributed Word files, email training lists and Excel tracking lose their evidential value in every inspection as soon as versioning and timestamps are missing. Anyone who takes KRINKO recommendations seriously needs a system that translates the recommendations into tasks, responsible persons and evidence and, when updates are made, automatically marks which documents need to be checked. It is precisely this bridge that a real compliance platform builds and not a loose document archive.

CIVAC offers this system as a compliance platform and officer-as-a-service. You can licence the workspace and operate it with your own hygiene representative or hospital hygienist or you can have our representatives appointed, the appointment certificate is issued and the reporting line to the management is documented. The 490 ready-to-use audit templates cover the typical inspection points, from hand hygiene compliance to reprocessing to MRE surveillance. The interfaces to data protection, ISMS and occupational safety are provided for in the platform data model so that MRE data, employee data and IT systems are in a consistent rights logic. Turn reading into an assignment. Write to info@civac.de or use the contact form on the hygiene officer page. Within 2 working days you will receive a proposal with modules, response times and an initial agenda for the first twelve weeks, including a hygiene plan review and training schedule. This means that the transition from a document-heavy status quo to platform-based hygiene control can be planned in a planned manner and not in a hectic inspection window. You retain technical responsibility in your own facility, but gain a consistent documentation and audit trail that can be relied upon in every inspection.
