Electronic health records are versatile tools where doctors not only record patient information but also organize the appointment schedule, manage the financial aspects of the practice, and store important documents not only of their patients but also of the clinic in general. In systems like Ninsaúde Clinic, doctors can store and access frequently used prescription templates, reducing the time spent on drafting new prescriptions and minimizing the possibility of errors.

Furthermore, the adoption of electronic health records facilitates the integration of information between different specialists and health units, allowing for a more holistic and coordinated view of patient treatment. This integration ensures that all parties involved in patient care have access to updated and accurate information, which is crucial for informed medical decision-making and promoting a more effective and safe treatment.

How Digital Medical Prescriptions Work

Digital medical prescriptions are a significant technological advancement in the healthcare field, providing a safer and more efficient alternative to traditional paper prescriptions. With digitalization, the process of prescribing medications becomes faster and less prone to errors, making life easier for both healthcare professionals and patients.

One of the key features of digital medical prescriptions is the requirement for a digital signature. This signature, which uses encryption technologies, ensures the authenticity and integrity of the prescription, confirming that the information has not been altered after being issued by the doctor. Additionally, for an extra layer of security and ease in verifying the validity of the prescription, it is common to include a QR Code. This code can be quickly scanned by pharmacies and other healthcare professionals to securely access the details of the prescription and confirm its validity.

In the context of digitalizing medical prescriptions, platforms like Ninsaúde Clinic play a crucial role. This system allows doctors to create, digitally sign, and send electronic prescriptions directly from their electronic health record system. Besides optimizing the prescribing process, Ninsaúde Clinic helps maintain compliance with medical data security regulations, offering an integrated solution that covers everything from appointment management to the issuance of digital prescriptions.

The implementation of digital medical prescriptions represents an important step towards modernizing healthcare services, offering not only greater security and precision but also promoting greater accessibility and convenience in medical treatment and medication procurement.

Validation of Digital Signatures in Prescriptions

Digital signature validation is a crucial step in the digital prescription process. It ensures that the prescription was indeed issued by an authorized professional and has not been altered after its issuance. To validate a digital signature, healthcare management software uses an encryption system that associates the doctor's signature with a specific document. This process is generally carried out through digital certificates, which are issued by recognized certifying authorities and ensure the authenticity of the signature.

Additionally, the validity of digital certificates is often checked in real-time by connecting to a central database that monitors the status of such certificates, ensuring they have not been revoked or expired. This security system is essential to prevent fraud and protect patient information, ensuring that only legitimate prescriptions are processed and dispensed by pharmacies.

In the United States, the validation of digital signatures on medical prescriptions is a carefully regulated process to ensure the security and authenticity of the prescriptions. This is particularly important for prescriptions of controlled substances, where regulations are more stringent. The validation generally follows these main steps:

Digital Certificates: The digital signature on a prescription is validated through digital certificates issued by recognized Certification Authorities (CAs). These certificates verify the identity of the prescriber.

DEA EPCS (Electronic Prescriptions for Controlled Substances): For controlled substances, the prescriber must use an electronic prescribing system that complies with the requirements of the DEA's EPCS program. This program requires that digital signatures use two-factor authentication.

Compliance with NIST Standards: Digital signature systems must meet the standards of the National Institute of Standards and Technology (NIST) for encryption and security. This ensures that the signatures are secure and cannot be easily forged.

Verification by the Pharmacist: After the prescription is transmitted electronically, pharmacists verify the digital signature against the prescriber’s digital certificate to ensure that the prescription has not been altered after signing.

Record and Audit: Electronic prescriptions and their digital signatures are stored in systems that allow for tracking and auditing. This helps prevent and detect any misuse or forgery of prescriptions.

Digital Prescriptions and Digital Signatures Legislation

United States: In the United States, the DEA (Drug Enforcement Administration) regulates the issuance of electronic prescriptions for controlled substances through the EPCS (Electronic Prescriptions for Controlled Substances) system. This system requires prescriptions to be digitally signed using two-factor authentication methods to ensure security.

Spain: In Spain, electronic prescriptions are regulated by the National Health System, which implements an interoperable electronic prescription system. The digital signature must comply with the standards set by the European Union, ensuring security and compliance across all member states.

Mexico: In Mexico, the regulation of digital prescriptions is still in development, but the process requires compliance with standards established by the Federal Commission for Protection Against Health Risks (COFEPRIS), which includes the use of advanced electronic signatures to validate the authenticity of prescriptions.

Brazil: In Brazil, the regulation of digital prescriptions and their signatures is addressed by the Federal Council of Medicine (CFM) and the National Health Surveillance Agency (ANVISA). The legislation allows for the issuance of electronic prescriptions, provided they are digitally signed with certificates issued by a Certifying Authority accredited by the Brazilian Public Key Infrastructure (ICP-Brazil). This ensures the authenticity and integrity of the prescription.

Digital Signature Validation in Prescriptions

United States: In the USA, validation is done through systems that adhere to EPCS regulations. The prescriber's digital signature is verified using two-factor authentication methods, and the system checks whether the prescriber is authorized to issue prescriptions for controlled substances.

Spain: In Spain, validation occurs through systems that check the digital signature against a digital certificate issued by a Certifying Authority recognized by the European Union. This ensures compliance with European security and privacy standards.

Mexico: In Mexico, digital signature validation on prescriptions is carried out through the recognition of the advanced electronic signature, checking its validity and authenticity through systems connected to certification authorities approved by COFEPRIS.

Brazil: In Brazil, digital signature validation is carried out by verifying the digital certificate linked to the signature. Pharmacies and other medical establishments use systems that automatically check the validity of the certificate by ICP-Brazil, ensuring that the prescription has not been altered and that the doctor is duly accredited.

The integration of digital signatures in digital prescriptions not only speeds up the medical process but also strengthens the drug custody chain, reducing errors and improving patient safety. The global trend is that this practice becomes increasingly common and regulated, ensuring efficiency and compliance in various health systems around the world.
