Understand how to make a digital signature in healthcare

The growing adoption of digital signature in healthcare has been transforming the way documents are validated and processed. With the digitization of medical records, prescriptions and medical records, digital signatures offer a practical and secure solution to guarantee the authenticity and integrity of information. 

Therefore, its use, while streamlining administrative and clinical processes, also ensures compliance with privacy and data security regulations.

For this reason, we created this article, revealing all the details on how to perform a digital signature in the healthcare sector and highlighting its practicality and importance in validating essential documents for the sector.

Digital signature in healthcare: benefits for doctors and patients

Digital signatures in healthcare are used by doctors to securely validate prescriptions, reports, medical records, and consent forms. They use an ICP-Brasil digital certificate to guarantee the professional's identity and the integrity of the document, ensuring that no changes have been made after signing. Thus, digital prescriptions can be legally accepted, providing convenience, security, and legal validity.

Unlike handwritten signatures, which can be easily forged or manipulated, digital signatures offer a significantly higher level of security, as they are based on cryptographic keys, which create a unique signature directly linked to the document and the signer.

Encryption also makes signing easily verifiable: When a document is digitally signed, any subsequent changes to the document will invalidate the signature, making any modification attempts visible.

This technology guarantees that the document is authentic and has not been tampered with, in addition to offering essential security and trust for environments in which the accuracy and validity of documents are the watchwords.

The implementation of digital signatures brings several significant benefits to the operations of companies in a wide range of sectors, and the healthcare sector is no exception.

Below, check out how the main benefits of digital signatures benefit this segment.

Security and integrity

The digital signature guarantees that documents have not been altered after signing, protecting the integrity of the data – which is especially important for the healthcare sector, where sensitive and confidential information needs to be kept secure against unauthorized access and manipulation.

Efficiency and agility

The adoption of digital signatures optimizes the time spent processing and approving documents in the healthcare sector. With this technology, medical prescriptions, informed consents and clinical records can be signed electronically, eliminating the need to print, sign manually and digitize physical documents. 

Thus, administrative processes are accelerated, improving operational efficiency in healthcare institutions.

Reduced costs

The adoption of digital signatures eliminates the need for paper, printers and physical document storage, resulting in a significant reduction in operational costs for healthcare institutions. 

Additionally, by reducing the possibility of errors and the need for rework, this technology contributes to additional savings and more efficient management of resources.

Legal and regulatory compliance

Digital signatures meet the legal requirements and regulatory, such as those established by the General Data Protection Law (LGPD) in Brazil and the Health Insurance Portability and Accountability Act (HIPAA) in the United States. 

This support helps healthcare institutions ensure compliance with data privacy and security standards.

Accessibility and convenience

With digital signatures, healthcare professionals can sign documents from anywhere and at any time, as long as they have access to the necessary technology – something particularly beneficial in telemedicine situations and for doctors who need to review and sign documents remotely.

Tracking and auditing

Digital signature technology allows tracking of all actions performed on the document, such as who signed, when and where – optimizing auditing and maintaining accurate records, essential for management and quality control in the healthcare sector.

How doctors can use digital signatures on prescriptions, reports and medical records

The application of digital signatures to electronic documents is a growing and valuable practice in healthcare, offering security, efficiency and regulatory compliance. 

Here is a breakdown of how to implement digital signatures in different types of medical documents, such as electronic medical records, prescriptions, reports and informed consents:

Electronic medical records

Electronic medical records are comprehensive records of a patient's medical information, and digital signatures offer a secure and efficient way to validate and authenticate changes to these records. 

To implement digital signatures in electronic medical records, the medical records system must be integrated with a digital signature platform, which allows doctors and healthcare professionals to sign electronic documents directly within the system.

The process begins when a healthcare professional makes changes or updates to the electronic medical record. After reviewing and finalizing the modifications, the professional uses his private key to digitally sign the document. This digital signature confirms that the medical record was reviewed and approved by the responsible professional, guaranteeing the integrity and validity of the information.

Once digitally signed, the signature can be verified by anyone with the corresponding public key, allowing other healthcare professionals or auditors to authenticate the signature and certify that the medical record has not undergone unauthorized changes since the signature.

Medical prescriptions

Digital signatures on medical prescriptions provide a safe and practical way to issue and validate electronic prescriptions. The process begins when the doctor fills the prescription into an electronic prescription system. 

After reviewing and confirming the prescription details, the doctor uses his private key to digitally sign the document. This digital signature guarantees that the recipe has been reviewed and approved by the professional and ensures the integrity of the information contained.

Once digitally signed, the prescription is automatically sent to the patient electronically and also stored in digital prescription management systems. This way, the prescription can be accessed quickly and safely by pharmacists and other healthcare professionals.

When the patient presents the prescription at the pharmacy, the pharmacist can use the corresponding public key to verify the validity of the digital signature. This procedure confirms that the prescription was issued by an authorized professional and that there were no changes to the content after signing.

Reports

Medical reports offer a detailed analysis of exams and diagnoses, being vital for the treatment and monitoring of patients. Digital signatures add significant value to these documents by allowing them to be created, reviewed and signed electronically in a secure and efficient manner.

When a doctor prepares a report, he uses his private key to digitally sign the document, which confirms the authenticity of the information and its approval by the professional. This digital signature validates that the report was reviewed and finalized by the responsible doctor, ensuring that the content was not altered after signing.

After signing, the report is distributed electronically to the patient and stored in digital report management systems. This approach facilitates quick and secure access to documents. 

Specialists and accompanying doctors can verify the authenticity of the report using the public key associated with the digital signature – which gives authority and reliability to the document, confirming that it was issued by an authorized and qualified professional.

Informed consents

Informed consent is a fundamental step in ensuring that the patient understands and authorizes a medical procedure before it is carried out. Digital signature simplifies and modernizes this process, allowing the consent form to be completed, reviewed and signed electronically by all parties involved.

The process begins with the electronic completion of the consent form, detailing the procedure, risks and available alternatives. 

After the doctor reviews and prepares the form, the patient uses their digital signature to confirm that they fully understand the information provided and consent to the procedure. Simultaneously, the healthcare professional digitally signs to validate that they have provided all the necessary information and obtained the patient's consent.

Once both digital signatures are applied, the document is stored electronically in a secure system. This eliminates the need for physical files, saving space and resources, but also allowing easy and quick access to the document by authorized parties. 

Other people or institutions that need to verify consent can access the document electronically and use the digital signature to confirm the authenticity and integrity of the consent, ensuring that all information is accurate and that the consent process was carried out in accordance with regulatory and security standards. security.
