Many hospitals and practices have invested heavily in digitalisation in recent years. Electronic patient records, digital informed consent sheets, hospital information systems (HIS) – the progress is visible. And yet there is one process step that is still carried out on paper in a surprising number of facilities: the medical history.
This has consequences – for process quality, for patient safety and for cost-effectiveness. This article analyses why the medical history is so often overlooked, what that means in concrete terms and what an end-to-end digital solution that includes the digital medical history looks like – with the pre-anaesthesia clinic as a prime example.
1. The digitalisation gap: what most hospitals overlook
Anyone walking through the admissions area of a modern hospital today will see tablets, screens and digital workflows. But behind this façade there is often a structural gap: digitalisation has reached everyday hospital life in many areas – but rarely as an end-to-end, integrated process.
A typical scenario: a patient receives their patient education documents digitally – via a link on their smartphone, with a video explanation and electronic signature. Up to date, legally sound, efficient. A few days later, they arrive at the hospital for the preparatory appointment and fill in a multi-page paper form – by hand, with illegible entries and no completeness check. The form is scanned, filed somewhere and has to be laboriously reworked by the physician during the discussion.
This scenario is not an isolated case. It is the reality in a large proportion of healthcare facilities in German-speaking countries. The medical history – the structured collection of the patient’s history, medication, pre-existing conditions and risk factors – is the step in the pre-admission process that most often remains on paper.
The blind spot: digitalisation is often understood as the sum of individual solutions – one digital tool here, another there. What is missing is the connection. The medical history is the missing link between patient intake and patient education.
2. The pre-anaesthesia clinic as a focal point
Nowhere is the weakness of the paper-based medical history as evident as in the pre-anaesthesia clinic. This is where all preoperative information comes together – and where the quality of the advance data directly determines patient safety and surgical planning.
Before every procedure, the anaesthetist has to carry out a risk assessment: what pre-existing conditions are there? What medication does the patient take? Are there allergies, coagulation disorders, cardiac risks? On the basis of this information, the ASA physical status classification is determined, among other things – and with it the anaesthetic approach. If the information is recorded by hand, a well-known problem is added: illegible handwriting can delay treatment and lead to errors, including wrong doses.
If this information is incomplete, illegible or late, real risks arise: delays in the OR schedule, follow-up questions shortly before the procedure and, in the worst case, decisions based on incomplete data.
Paper-based vs. digital medical history in the pre-anaesthesia clinic
| Paper-based process | Digital process |
|---|---|
| The patient fills in a paper form in the waiting room. Illegible entries, missing information, no completeness check. The form is scanned and transferred manually into the HIS. The physician fills the gaps during the discussion. | The patient receives a structured digital medical history form in advance – at home, on their smartphone. Mandatory fields, upload of findings, plausibility checks, automatic transfer to the HIS. The physician is fully informed before the discussion. |
Even today, digitalising the pre-anaesthesia clinic would be entirely feasible from a technical point of view. In many places, however, the historical process is still maintained.
The time factor: preparation vs. rework
In a paper-based workflow, an anaesthetist spends a considerable part of the preparatory discussion asking for information that the patient could have provided long ago. A digital medical history taken in advance shifts this work to where it belongs: to the patient, ahead of the appointment. The discussion in the clinic can then concentrate on what matters: clinical assessment, questions and patient education.
3. What happens when medical history and patient education do not work together
Medical history and patient education are not separate processes – they are two sides of the same coin. The medical history provides the information on which patient education has to be individualised. Running the two in isolation forfeits the decisive advantage.
Lack of individualisation as a legal risk
As described in the previous article: courts require patient education tailored to the specific patient. However, if the physician only learns during the consent discussion that the patient has a pacemaker or takes anticoagulants, they can no longer individualise the patient education in advance. The result: either time-consuming rework – or standardised patient education that is legally vulnerable.
Medication risks and interactions
One of the most common reasons for surgical delays or cancellations is the late discovery of contraindications arising from the patient’s concomitant medication. Aspirin (ASA), phenprocoumon (Marcumar), newer anticoagulants – the list of perioperatively relevant medicines is long. A structured digital medical history can record and evaluate this information at an early stage and – with appropriate system integration – automatically check it for relevance.
Information loss through media discontinuities
Every switch between paper and digital is a potential point of error. Information that is recorded on paper, then scanned, transferred manually and finally processed further in another interface loses quality. Typing errors, transcription errors, forgotten fields – the media discontinuity is a structural quality problem. A study of handwritten drug prescriptions at a Swiss university hospital shows how error-prone handwriting is: 43% of patient charts contained at least one documentation error. Per prescribed drug, the error rate was 3.5%.
4. The follow-on costs of the paper-based medical history
The effort involved in a paper-based medical history is rarely directly visible – it is spread across many small losses of time and quality. A structured analysis shows, however, that the cumulative costs are considerable.
Staff time
Medical assistants scan forms, re-type data and chase missing information. Anaesthetists and other physicians ask during the discussion for information that should have been available in advance. Every one of these minutes is paid specialist time that is missing elsewhere.
Operating theatre efficiency
Incomplete or incorrect advance information is one of the most common causes of delays in the OR schedule. Depending on the facility and type of procedure, a postponed procedure costs several hundred to a thousand euros in direct theatre costs, quite apart from the effects on subsequent procedures and patient satisfaction.
Patient experience
Patients who have to fill in long forms at the hospital experience the admission process as cumbersome and unappreciative. A digital medical history taken in advance, which the patient can complete conveniently at home on their smartphone, signals: this facility respects my time.
The question is not whether a digital medical history is worthwhile – but how much longer you can afford the paper-based one.
5. What a fully digital pre-admission process looks like
An end-to-end digital pre-admission process does not begin in the waiting room – it begins at the patient’s home. The following process chain shows how medical history and patient education work as an integrated workflow:
Step 1: Digital appointment confirmation with advance questionnaire
Once the appointment has been made, the patient automatically receives a link to a structured, mobile-optimised medical history form. Mandatory fields ensure completeness. Plausibility checks prevent obvious input errors. The patient completes the form calmly at home – without time pressure, without a waiting room.
Step 2: Automatic transfer and preparation
The answers are recorded in structured form and transferred directly to the HIS or PMS. Relevant information (e.g. concomitant medication, pre-existing conditions, allergies) is clearly prepared for the treating physician and summarised in the briefing.
Step 3: Individualised patient education based on the medical history
On the basis of the medical history data, patient education is individualised automatically: the patient’s risk factors are woven into the patient education content, specific notes are added and language barriers are overcome with multilingual content. The patient receives patient education tailored to them – with video, digital consent sheet and electronic consent.
Step 4: Physician discussion with a complete information base
When the patient arrives for the preparatory discussion in the pre-anaesthesia clinic, all relevant information is already available in structured form. The discussion can focus on clinical assessment, questions and the personal encounter – not on data entry.
Step 5: Consent trail and audit-proof documentation
All steps – medical history, patient education, consent – are documented in full: with time stamp, IP address and consent trail. In the event of a legal dispute, the entire process chain is traceable and has evidential value.
Conclusion: think in end-to-end processes, not isolated solutions
Digitalising healthcare is not a sprint – but it needs a clear goal: end-to-end, integrated processes without media discontinuities. The medical history has long been the forgotten step in this process. That is changing.
Especially in the pre-anaesthesia clinic, where preoperative data quality is directly linked to patient safety and surgical efficiency, the digital medical history is not a nice-to-have – it is a strategic building block for a modern, safe and cost-effective hospital organisation.
Thinking of medical history and patient education as an integrated process brings gains on several levels: less lost time, higher data quality, greater legal certainty – and patients who feel well looked after from the start.
