A Complete Guide to Integrating SMART Apps with Cerner EHRs

Healthcare providers use electronic health records (EHRs) to manage patient data digitally. However, clinician workflow frustrations with many mainstream EHRs like Cerner reveal integration limitations constraining efficiency and insights from that data.
SMART (Substitutable Medical Applications, Reusable Technologies) on FHIR (Fast Healthcare Interoperability Resources) offers an integration framework allowing web apps to connect an EHR safely to expand functionality. By following key technical and design steps, third parties can develop SMART apps adding value to Cerner. This guide covers considerations for planning, building, and deploying reliable integrated SMART apps with Cerner to avoid pitfalls.

Planning a SMART App Integrated with Cerner

The first phase entails aligning to core needs and defining the app scope. Conduct user research to identify pain points within Cerner workflows. Discover usability obstacles and wish list items to tackle in the app. Also, analyze relevant data transactions in Cerner APIs to serve as building blocks.
With requirements mapped, outline planned capabilities, data flows, clinical touchpoints, and technical integrations. Healthcare workflows intertwine many complex systems, so conceptual modeling helps set expectations on feasible SMART on FHIR integration depth for initial versions.

Key Design Decisions for Cerner SMART App Development

Several pivotal choices guide design processes:
Pick FHIR Resources – FHIR provides schema and APIs for clinical data exchange. Review available Cerner FHIR resource options to identify optimal data targets for the app such as medications, imaging reports, or diagnoses.
User Experience Design – Design intuitive clinician-centered interfaces for the app enhancing Cerner. Iterate wireframes focusing on simplifying current hindrances.
Medical Standards Usage – Adopt terminology standards for representing data including SNOMED, LOINC, and RxNorm to enable seamless data sharing with Cerner.
Security and Compliance Policies – Build consent flows and access controls aligned to healthcare security regulations around handling sensitive patient information accessed via Cerner APIs.
Scalability Plans – Design modular components to handle usage spikes in hectic hospital settings with large concurrent user bases.

Technical Implementation Steps

With designs firming up, move into the development and deployment stages:

1. Register the SMART app to obtain client credentials for Cerner authorization.
2. Implement SMART on FHIR client JavaScript libraries for API requests.
3. Connect to Cerner’s FHIR API endpoints to search, read, and write agreed-upon FHIR resources.
4. Construct UI application logic and views applying best UX practices.
5. Handle FHIR resource data mappings, terminology translations, errors, and loading states.
6. Develop robust authorization token handling for reliable integrated sessions.
7. Build automated testing harnesses simulating workflows.
8. Partnership with a healthcare provider to test in Cerner staging environments under live data loads.
9. Deploy the application with scaling, security, and redundancy measures.
10. Monitor adoption, user feedback, and integration stability.
11. Maintain continuous delivery pipeline for updates addressing bugs and new features.

By navigating these planning, development, and deployment stages thoughtfully when integrating with Cerner’s complex EHR environment, healthcare innovators can successfully deliver SMART apps advancing clinician productivity and data-driven care quality. 
Extensible integration frameworks enable possibility despite the limitations of mainstream platforms like Cerner. Delivering simple but profound workflow and functionality gains through focused apps makes achievable improvements tangible.
