Gesundheitswesen

Healthcare data integration brings together information from disparate IT systems, giving medical organizations holistic data management capabilities and a 360-degree view of their data.

Now, integrating healthcare information is more crucial than ever. Annually, providers generate around 30 petabytes of data — clinical, administrative, analytical, and financial. However, almost half of it (47%) remains underutilized when delivering care and business decisions. Thanks to integration, healthcare businesses can tap into all that valuable information scattered across various systems without letting any significant details fall through the cracks.

Trends prompting data integration in healthcare

Aside from the mismatch between data volumes and data utilization, other factors contribute to the rising need for healthcare data integration.

Adoption of cloud-based solutions and APIs

Laut PwC, about 81% of healthcare providers have adopted cloud solutions, so medical professionals are getting used to more convenient data access. API-centric medical apps also set the bar high, offering a glimpse into truly integrated healthcare data. These factors contribute to the growing need for organization-wide data integration.

Expansion of telemedicine and remote care

The adoption of telehealth has increased in recent years, and now the technology is used for various medical specialties — primary or urgent care, mental health, cardiology, endocrinology, etc. In the years to follow, care digitization will only grow, venturing into remote surgery and diagnostics realms. It will spur demand for comprehensive patient data that can be conveniently accessed during online consultations.

Growing use of AI, ML, and predictive analytics

The healthcare AI market is predicted to expand at a 37% CAGR between 2024 and 2034, reflecting the growing confidence in predictive, prescriptive, and generative artificial intelligence among the medical community. To distill reliable insights with AI, healthcare data integration is a must, and many medical organizations agree — 55% plan to aggregate unstructured data for further analytics.

Focus on personalized care

Recently, there’s been a much bigger focus on tailored care, accelerated by advances in precision medicine and push for better health outcomes. To personalize care, medical institutions must integrate multiple data points — everything from patient-generated health information to medical history collected by different providers — and it incites the need for data integration.

Adoption of interoperability standards

Government agencies continue to develop regulatory frameworks supporting interoperability standards, like HL7 or FHIR, necessary for healthcare data integration. This has led to steady growth in their use. According to the National Survey of Health Information Exchange Organizations, now more than 80% of healthcare organizations share HL7 v2 messages, and 22% use FHIR APIs for data exchange.

Growing adoption of HIE systems

Recent government initiatives and incentives boost the adoption of HIE (health information exchange) software across the healthcare industry, driving the market CAGR of 9.7% from 2024 to 2030. This regulatory push also stimulates new medical data integration projects among the providers, making data sharing with partnering organizations more seamless than ever.

Rise of IoT-powered real-time health monitoring

Using wearable medical devices proved to be an efficient way for doctors to continuously monitor patient state, compared to in-person assessments and manual vitals tracking. By integrating the device-collected data in patient care, healthcare providers can tackle the onset of chronic diseases, avoid disease complications, and improve treatment outcomes.

Strengthening data security regulations

The regulatory oversight in the healthcare domain becomes even more rigorous, especially regarding data privacy. Storing data in disparate systems with different security measures in place puts data privacy at risk, so it further encourages data integration in healthcare.

Use of blockchain for data management

The global healthcare blockchain market is expected to grow at a CAGR of 63.3% from 2024 to 2030, with a substantial market share belonging to health records storage and exchange solutions. When used to manage integrated medical data, blockchain enables exceptional data access transparency and reliability.

Data security and compliance essentials

In 2023, large-scale data breaches in US healthcare institutions peaked, reaching 745 cases. With privacy threats at an all-time maximum, security and compliance become top priorities during healthcare data integration, highlighting the need for compliant design, robust security measures, and continuous monitoring.

Compliance by design

Compliance with HIPAA, GDPR, or other applicable data privacy regulations is the cornerstone of healthcare data integration projects. From the get-go, it’s best to analyze what regulatory rules apply to your business, detect and address potential compliance risks, and plan security measures respectively. To ensure compliance with the data privacy regulations, we recommend following information security standards, like ISO 27001, and establishing robust data governance frameworks within the organization.

Data encryption and cybersecurity measures

Core security measures for healthcare data integration include SSL and TLS-based data encryption (both in transit and at rest) and API authentication mechanisms, like OAuth or API keys. To add a new layer of security for health data, it’s a good practice to employ data masking during integration testing or data transfer, as well as data segmentation based on sensitivity level.

Continuous security monitoring and routine audits

Security measures do not stop after the healthcare data integration. Automated security monitoring systems — like SIEM and RMM — will help keep an eye out for security threats, detecting vulnerabilities and unauthorized data access attempts in real time. Regular patch management penetration testing, security and compliance audits will help proactively identify and tackle any compliance risks that may eventually lead to hefty fines.

Standards for data integration in healthcare

Thanks to standardization, healthcare systems can speak the same language, using common codes and message formats. This universal approach makes it much easier to share patient information accurately and securely.

Clinical data exchange standards

HL7 v2 and HL7 v3. These messaging standards set guidelines for sharing clinical and administrative data between applications using proprietary or XML-based structures.
FHIR. The standard describes electronic health data exchange rules: formats, key elements, and APIs. FHIR uses the HTTPS protocol, which makes the standard compatible with multiple IT solutions, including legacy ones.
DICOM. This technical standard specifies the ways to share medical images, like ultrasound, X-ray, or MRI scans, and their metadata.
CCD. US-specific XML-based markup standard details exchange protocols for medical summaries.
X12. The standard sets rules for message formatting of Electronic Data Interchange (EDI) documents and is often used by healthcare insurance companies and clearinghouses.
SCRIPT. Developed by NCPDP (The National Council for Prescription Drug Programs), it regulates the ways of sharing electronically transmitted medical prescriptions in the United States.

Terminology standards

SNOMED CT. A comprehensive set of clinical terms and codes covers clinical findings, symptoms, diagnoses, procedures, body structures, substances, pharmaceuticals, etc.
LOINC. The standard provides codes for medical laboratory observations.
CPT. Used in the US, the standard sets codes for medical, surgical, and diagnostic procedures.
HCPCS. It expands the CPT standard and covers non-physician and ambulance services, as well as items and supplies used.
ICD-10. The international coding standard offers a solid framework for the classification of diseases, signs, symptoms, findings, complaints, etc.
RxNorm. A terminology standard aggregating names of clinical drugs available on the US market.
