The patient’s medical record: what it is and why it matters

The patient’s medical record is the legal document that consolidates, in chronological order, the clinical, care and administrative information of a healthcare encounter. It is a central instrument for continuity of care, patient safety, legal backing and the financial viability of institutions.

In data-driven hospital operations, the accuracy of the record directly affects care indicators, audit cycles and regulatory compliance.

How is the patient’s medical record regulated?

The nature of the medical record is defined by strict rules. In Brazil, Federal Council of Medicine (CFM) Resolution No. 1,638/2002 characterizes the document as a mandatory repository of information that must be kept under the responsibility of the attending physician and the institution. Its contents must be exhaustive:

• Identification and history: a detailed record of the clinical history, lifestyle habits and social context.

• Physical examination and diagnostic hypotheses: the technical basis for the clinical reasoning applied to the case.

• Test results and treatment decisions: diagnostic evidence and the treatment plan put in place.

• Multidisciplinary progress notes: daily reports from physicians, nursing, physical therapy and other specialties.

• Informed consent forms (ICFs): ethical documentation that ensures patient autonomy and protects the professional.

• Administrative and billing data: information essential for procedure coding and bed management.

The document is protected by professional confidentiality and must fully comply with the LGPD (Brazil’s General Personal Data Protection Law), since it stores sensitive data that require strict encryption and access control protocols.

The importance of the medical record for clinical documentation and hospital management

The importance of correct medical record documentation rests on four dimensions:

1. Continuity of care

In highly complex hospital structures, care is fragmented across multiple teams and shifts. The medical record acts as the only reliable channel for passing on data. Clear documentation allows the treatment plan to be carried out without interruption, optimizing length of stay and increasing the bed turnover rate.

2. Patient safety

The record is an error-prevention tool. Medication errors, omissions of known allergies and unnecessary repetition of invasive tests often originate in incomplete medical records. Standardized records make it possible to implement safety protocols, such as those for sepsis and surgery.

3. Legal backing and documentary evidence

The medical record is the supreme material evidence in ethics or court proceedings. In medical law, the principle is that the record is the factual truth of the care provided. A detailed progress note documents compliance with technical standards and the team’s diligence, protecting the hospital and its professionals against allegations of negligence or malpractice.

4. Revenue cycle

The quality of clinical documentation determines the institution’s financial health. Documentation inconsistencies are the main causes of avoidable losses:

• Coding and DRG: accurate records enable the use of payment models based on DRG (Diagnosis Related Groups), which classify the cost of care by diagnostic complexity.

• Claims auditing: payer audits look for discrepancies between what was consumed and what was recorded. A weak medical record results in irreversible denials.

• Billing: detailed recording of materials, high-cost drugs and medical gases ensures that the charge faithfully reflects the use of supplies.

The transition to the electronic health record (EHR)

The obsolescence of the physical (paper) model is a reality. The electronic health record (EHR) eases long-standing problems of legibility, deterioration and the impossibility of simultaneous access. Beyond the convenience of digitization, the EHR offers:

• Clinical decision support (CDSS): real-time alerts about drug interactions or critical test results.

• Interoperability: native integration between the clinical history and laboratory and imaging systems (PACS/RIS), providing a holistic view of the patient.

• Compliance and traceability: access logs that record who viewed or changed data, fully meeting audit and cybersecurity requirements.

Conclusion

The medical record is the most critical information asset of a healthcare facility. Its management goes beyond the clinical sphere and is vital to corporate governance and financial sustainability. Hospitals that invest in a culture of documentation and in data technology ensure excellence in care, compliance with legal obligations and the economic predictability of their operations.
