Digital audit trail in healthcare: event logs for CSSD and operating theatres
How to structure a digital audit trail for healthcare audits and reviews
A digital audit trail in healthcare is a chronological record documenting the activities carried out within a department, making it possible to reconstruct who performed a specific action, when it took place and what information was recorded or modified. In Central Sterile Services Departments (CSSDs) and operating theatres, having a digital audit trail means being able to follow the different stages of a process and retrieve reliable data when needed for audits, quality control and event reconstruction.
It should therefore not be confused with a clinical audit in healthcare, which is a broader process for assessing the quality of care. An event log is instead one of the sources of information that can support a healthcare audit.
For Promedital, digitalising these processes means replacing fragmented information and paper-based documentation with structured, traceable data that remains accessible over time through dedicated systems.
What events should an audit trail in healthcare record?
An effective audit trail in healthcare should not collect every piece of information indiscriminately: it should record the events required to reconstruct the process and clearly attribute the activities performed. In general, a digital log should make it possible to identify the user, action, item concerned, date and time of the event, and the before-and-after status of each specific activity. Depending on the system, access records, changes, anomalies and administrative operations may also be relevant.
Applied to CSSD and operating theatre processes, this means structuring traceability so that, where relevant, the following can be documented:
- operator identification and activities performed;
- date and time of the different operations;
- progression of a device, set or material through the various stages;
- checks performed and their outcomes;
- anomalies and non-conformities identified;
- changes made to information and user activities;
- data relating to sterilisation stages and the use of materials throughout the surgical pathway.
The aim is not simply to accumulate logs, but to build a coherent, searchable sequence of events. Healthcare audit management software and traceability systems therefore become genuinely useful when they make it possible to follow the different stages of a process and quickly retrieve the required information, without having to reconstruct it from separate registers, paper documents or systems that are not interconnected.
The availability of complete evidence is also particularly important in medical-legal risk management, where the ability to reconstruct activities objectively helps make the process verifiable.
Roles, access and data integrity: when is an event log truly reliable?
Recording events is only the first step. For a digital audit trail to provide a reliable source of information during an internal healthcare audit or review, activities must be attributable to individual users, access must be properly managed and the integrity of information must be preserved over time. The ability to retrieve and review logs is equally important: recording activities without being able to access and analyse them when required significantly reduces the value of the audit trail.
In practical terms, it is therefore necessary to define roles and access permissions, establish which operations different users are authorised to perform and maintain a sufficiently detailed history to understand what has occurred. The management of signatures and approvals must also be consistent with the responsibilities established for each process. Similarly, retention periods and methods should be defined according to the data being processed, the healthcare organisation’s procedures and the applicable regulatory requirements.
An event log is genuinely useful when information can be reliably attributed, contextualised and retrieved whenever it needs to be reviewed.
Digital audit trails in CSSD and operating theatres: SIXSTER and SISOS
In Central Sterile Services Departments, digital traceability makes it possible to document the activities associated with surgical instruments throughout reprocessing. With SIXSTER, the surgical instrument traceability system, Promedital digitalises CSSD management and traceability processes, enabling information generated at different stages to be collected and made available.
The system makes it possible to track instruments through activities such as receipt, washing, packaging, sterilisation and dispatch, while also recording information received from machinery and other devices connected to the software. Data from the different stages can therefore be stored digitally and retrieved for subsequent monitoring and review, rather than remaining confined to paper documents or isolated records.
The same principle extends to the operating theatre with SISOS, Promedital’s software for managing the surgical pathway. The system enables integrated management of operating theatres, staff, materials and time, while collecting information generated throughout the different stages of surgical activity. The availability of data from both the operating theatre and CSSD therefore supports greater information continuity between closely interconnected processes.
More broadly, the digitalisation of operating theatres makes structured data available for audits, clinical reporting and quality control.
The value of this continuity becomes particularly clear when an event needs to be reconstructed. In the case of a review relating to a specific surgical procedure, for example, information available across the different systems may make it possible to trace the documented activities performed on the instruments during reprocessing and the data associated with their subsequent use in the surgical pathway, within the limits of the information recorded by each solution. Rather than consulting a single event in isolation, users can review the documented sequence of activities affecting the process as a whole.
From the audit trail to the healthcare audit: what makes an event log effective?
An effective digital audit trail in CSSD and operating theatres should make it possible to identify the recorded event, attribute it to a user, establish when it occurred, verify its outcome and retrieve the relevant information when required. These elements, rather than simply the volume of data stored, are what make an audit trail genuinely useful during internal audits, reviews and quality control activities.
Digitalisation also makes it possible to overcome some of the typical limitations of documentation distributed across paper records, files and separate registers. With healthcare audit software and traceability solutions, the different stages of a process can be documented within a structured workflow, while digital archiving makes data available to authorised users for subsequent consultation. In cloud-based architectures, where supported by the solution adopted, information can also be made accessible to authorised users and devices in accordance with the policies defined by the healthcare organisation.
An “inspection-ready” event log is therefore more than simply a digital archive: it is a system in which completeness, attribution, chronological sequencing, integrity and retrievability of information make it possible to understand and document what has occurred throughout the process.
