Selecting the right electronic health record (EHR) system directly affects efficiency, compliance, and patient care.
The problem is, EHRs come in different forms; each with distinct costs, benefits, and limitations.
Some offer stronger data security but require major IT resources, while others keep expenses low but restrict flexibility. Many vendors also label systems as “cloud-based” when they’re little more than hosted servers.
In this guide, we’ll break down the main types of EHR systems, their strengths and weaknesses, and what they mean for your operations.
Key Takeaways
- Four main EHR deployment models exist: on-premises, ASP-hosted, SaaS, and true cloud-based systems; each with distinct cost structures, control levels, and scalability potential.
- Data ownership and control vary significantly: On-premises systems give you full control but require IT expertise, while cloud systems offer convenience but may limit your data access.
- Interoperability isn't automatic: Many EHR systems claim connectivity but actually operate in silos, preventing critical data exchange between providers.
- Hidden costs can derail budgets: Beyond licensing fees, consider maintenance, updates, compliance, training, and potential vendor lock-in scenarios.
- Custom integration often bridges gaps: When off-the-shelf EHR systems fall short, partners like Pi Tech can develop tailored solutions that connect disparate systems and optimize workflows for your specific practice needs.
What Is the Difference Between EHR and EMR in Healthcare?
Before looking at deployment models, it’s important to separate two terms often used interchangeably: EMR and EHR.
The difference shapes how data is shared, how care is coordinated, and how patients experience the healthcare system.
EMR Systems: Digital Charts Within Your Walls
Electronic Medical Records (EMR) are the digital version of paper charts. They document patient encounters, store test results, and track treatment history but only within a single practice or organization.
For example, an endocrinologist can use an EMR to track a diabetic patient’s A1C trends and medication changes.
The system works well inside the practice. But if that patient shows up in an emergency room, those records stay locked in the EMR. Other providers, specialists, and sometimes even the patient can’t access the data. The result is fragmented care and potential safety risks.
EHR Systems: Connected Healthcare Across the Continuum
Electronic Health Records (EHR) are built for sharing. They connect across authorized providers, giving a complete health record that follows patients wherever they receive care.
EHRs use standardized formats and secure exchange protocols to integrate with labs, pharmacies, imaging centers, health information exchanges, and even insurance systems. This means lab results file automatically, prescriptions come with drug interaction checks, and referrals move with the patient.
The impact is direct: cardiologists see blood pressure trends from primary care, ER doctors avoid dangerous interactions by viewing complete medication lists, and follow-up care improves because providers instantly see each other’s notes.
What Are the Types of Electronic Records?
Healthcare IT hasn’t stood still. Each deployment model emerged to solve specific challenges: first came physician-hosted systems for complete control, then remotely hosted systems to reduce infrastructure burdens, followed by SaaS platforms that redefined interoperability, and finally full-service cloud models that blend technology with operations. Understanding this evolution makes it easier to see which option fits your practice today.
1. Physician-Hosted Systems: Complete Control with Complete Responsibility
This is the most traditional approach. Servers live in your facility, data never leaves your network, and every configuration is under your control. That level of autonomy appeals to practices handling highly sensitive data or large health systems with IT teams already in place.
But control has a cost. Your staff must manage:
- Server maintenance, power redundancy, cooling, and physical security
- HIPAA safeguards like encryption, audit logs, and risk assessments
- Disaster recovery planning for floods, fires, or ransomware
Costs are also significant:
- Software licensing: $15,000–$50,000 per provider
- Hardware: $25,000–$100,000, depending on size
- Maintenance contracts: 18–22% of software costs annually
Interoperability is another challenge. Records often remain siloed unless you build custom interfaces, which can quickly become costly when multiple integrations are required.
2. Remotely-Hosted and ASP Models: Shifting Infrastructure, Not Innovation
As practices sought to avoid maintaining server rooms, ASP vendors offered to host the system for them. Your data lives on the vendor’s servers, and they handle backups, power redundancy, and physical security. For small practices, this removed a major barrier.
Hospitals sometimes subsidize these systems for affiliated clinics, making them affordable. But the underlying structure hasn’t changed, you still run an isolated instance, meaning ten practices on the same vendor operate in ten silos.
Often market ASP as “cloud-based,” but these systems lack the scalability, automatic updates, and shared integrations of true cloud solutions.
Contracts also demand attention. Some vendors restrict data portability or impose high fees if you leave, creating vendor lock-in that has nothing to do with technology value.
3. Software as a Service Platforms: The Power of Shared Infrastructure
SaaS marked a real turning point. Instead of each practice running its own software instance, everyone accesses a single evolving platform through a browser.
Updates happen automatically, new features appear without disruption, and all users benefit from the same security patches.
What makes SaaS transformative is interoperability. Once the vendor builds a connection to a lab or pharmacy, it’s instantly available to every customer. Shared infrastructure also creates collective intelligence:
- Medication alerts improve with real-world prescribing data
- Quality benchmarks are based on thousands of practices
- Best practices spread across the network quickly
The business model matches this flexibility. Subscription pricing removes huge upfront costs, while vendors must deliver continuous value to keep you subscribed.
4. True Cloud-Based Healthcare Services: Where Technology Meets Operations
The latest step goes beyond software delivery. True cloud-based healthcare services combine SaaS technology with built-in operational support. Vendors don’t just provide a platform; they help manage revenue cycles, compliance, and documentation.
This model especially benefits smaller practices without full administrative teams. You get access to experts in coding, denial management, and regulatory compliance without hiring in-house. Many platforms now integrate AI for clinical documentation, predictive analytics, and patient risk management. Marketplaces extend functionality with specialty-specific apps that plug directly into workflows.
The trade-off is deeper dependence on the vendor ecosystem and higher subscription fees, but the payoff is a partner that supports both your technology and your operations.
What Are 5 Common Functions of EHR Systems?
Modern EHR systems go well beyond storing records. They integrate tools that influence how providers deliver care, how patients stay engaged, and how organizations manage safety and compliance.
The following five functions represent the backbone of most systems, and understanding them helps you judge whether a particular platform meets your needs.
1. Clinical Documentation: The Foundation of Patient Care
Documentation is still the core of an EHR, but the way it works has evolved dramatically. Providers are no longer limited to typing into rigid templates. Today’s systems support:
- Voice recognition that converts dictation into structured notes, often reducing charting time by 40–50%.
- Ambient AI listening that captures natural conversation during visits and automatically generates notes.
- Template libraries, smart phrases, and macros that ensure consistent, complete records while saving time.
The shift toward structured data capture is especially important. Instead of storing everything as free text, problem lists, vitals, and medications are stored in standardized formats. This makes information easier to analyze and powers decision-support tools.
The challenge, however, is maintaining accuracy: shortcuts like copy-paste can save time but risk propagating errors. Leading systems counter this with safeguards that flag inconsistencies.
2. Order Management and Clinical Decision Support
Once information is documented, the next step is acting on it through provider orders. Computerized Provider Order Entry (CPOE) eliminates handwriting errors and adds safety checks in real time.
- Orders are validated against allergies, medications, lab results, and guidelines before they’re finalized.
- Evidence-based order sets streamline care for common conditions.
- Preference lists adapt to provider habits without compromising safety.
- Corollary orders automatically suggest related steps (e.g., ECGs when cardiac enzymes are ordered).
The biggest risk here is alert fatigue. Too many pop-ups can cause providers to ignore critical warnings. Advanced systems address this by using context-aware algorithms that filter out low-value alerts and emphasize the ones that truly matter.
3. Results Management: Turning Data Into Decisions
Lab and imaging results are central to patient care, and modern EHRs handle far more than just storing them. Systems automatically route results to the correct chart sections, flag abnormal values, and issue alerts for critical findings.
What makes this powerful is visualization. Instead of scanning numbers, providers can trend results over time to reveal patterns. For example, plotting a diabetic patient’s A1C values over years shows whether treatment is effective. Overlaying medication changes on lab graphs helps evaluate cause and effect.
Integration is seamless for routine labs but more difficult for advanced diagnostics such as genomics or specialized pathology. The strongest platforms prepare for this by offering flexible tools to integrate emerging test types without requiring manual workarounds.
4. Medication Management and E-Prescribing
Medication safety is one of the most visible benefits of EHRs. Electronic prescribing removes the problem of illegible handwriting and adds multiple safety layers.
- Drug–allergy checking prevents dangerous exposures.
- Interaction analysis flags harmful combinations.
- Dose range validation ensures prescriptions fit the patient’s age, weight, and kidney function.
- Formulary integration suggests lower-cost or covered alternatives, easing prior authorization delays.
One of the toughest challenges is medication reconciliation. Patients often see multiple providers, fill prescriptions at different pharmacies, and sometimes fail to follow instructions. EHRs aggregate this information from multiple sources, but it still requires careful human review to resolve discrepancies.
5. Patient Engagement and Portal Technologies
The final function is about extending the EHR beyond the clinic walls. Patient portals allow individuals to access records, view test results, and communicate with providers directly. They also let patients request refills, schedule visits, and fill out intake forms before appointments.
This level of transparency can be a double-edged sword. Patients may see abnormal results before providers can explain them, creating anxiety. But when implemented thoughtfully, portals improve outcomes by fostering active involvement.
Modern platforms go further by connecting educational materials, automated reminders, and even remote monitoring tools like blood pressure or glucose trackers. For chronic disease management, this continuous flow of data supports better long-term care.
The Hidden Infrastructure: Security, Compliance, and Integration Challenges
Behind every polished EHR interface lies a complex infrastructure that determines how secure, compliant, and interoperable your system really is. These factors often get less attention during selection but can define the system’s long-term success.
Two areas stand out: meeting evolving security and compliance demands, and overcoming integration challenges that affect care coordination.
Navigating HIPAA and Beyond
HIPAA sets the baseline for healthcare data protection, but in practice, it’s only the starting point. Modern threats require defense-in-depth strategies that extend far beyond basic compliance. An effective EHR should support:
- Encryption of data both at rest and in transit
- Multifactor authentication for every user
- Role-based access controls with granular permissions
- Detailed audit logs of every access and change
- Automatic timeouts that log users out after inactivity
Regulatory complexity doesn’t stop at HIPAA. States like California, Texas, and New York impose their own requirements; from stricter breach notifications to mandatory encryption on portable devices. Multi-state providers must comply with the highest bar across jurisdictions, which makes vendor choice critical.
International considerations add yet another layer. Serving foreign nationals may trigger GDPR obligations. Telemedicine across borders can involve multiple overlapping regulatory frameworks.
Even where cloud servers are physically located can raise sovereignty concerns. These realities often require not just technical safeguards, but also careful vendor vetting and legal consultation.
The Integration Imperative
The real promise of EHRs lies in coordinated care, but that depends on seamless information exchange.
Here, integration remains one of the industry’s toughest challenges; partly technical, but just as much financial and organizational.
Technical hurdles: Healthcare data standards are still fragmented. HL7 v2 remains common despite its limitations. FHIR offers better interoperability, but implementation is inconsistent across vendors. Direct messaging supports secure communication, yet it only works if both sides are enrolled. In reality, true integration often requires supporting multiple standards simultaneously.
Financial barriers: Building interfaces is rarely cheap. A simple one-way connection to a lab might cost $5,000, while a complex bidirectional interface with a hospital system can exceed $50,000. On top of that, annual maintenance typically adds 15–20% of the initial cost. For practices that need multiple lab, imaging, hospital, and health information exchange connections, integration expenses can easily outpace the EHR license itself.
Organizational challenges: Even when the technical and financial pieces are in place, people and policies can block progress. Data sharing agreements need legal review. Governance structures must clarify liability and privacy responsibilities. And in competitive markets, health systems may actively resist sharing data, even when it would clearly benefit patient care. These human factors often prove more difficult than the technical ones.
Making EHR Systems Work: Implementation Strategies and Success Factors
Choosing an EHR system is only the first step. What really determines success is how the system is implemented, how staff adapt to it, and how the organization continues to refine its use over time.
A good EHR can transform care delivery, but without the right strategies, it can just as easily become a daily frustration.
The Implementation Journey
Most EHR projects follow a similar path, usually lasting 6–12 months. The stages are predictable, but each requires a different mix of resources, planning, and focus.
1. Pre-implementation planning (2–3 months):
This is the stage where success is either made or lost. Careful preparation prevents small issues from snowballing later. At this point, practices should:
- Analyze current workflows to remove inefficiencies rather than simply digitize them.
- Plan data migration so that historical records remain accessible.
- Assess hardware and network infrastructure for necessary upgrades.
- Evaluate staff readiness and tailor training accordingly.
It’s tedious work, but skipping it almost always leads to problems later.
2. System configuration and testing (2–4 months):
The next step is making the system your own. Instead of relying on vendor defaults, successful practices customize workflows, templates, and alerts to match their operations. Integration testing is critical: labs, pharmacies, and external partners must connect seamlessly.
This phase is resource-intensive, requiring input from both clinicians and administrators.
3. Training and readiness:
Training isn’t just about teaching people how to click through screens. It’s about showing each role, physicians, nurses, administrators, how the system supports their day-to-day work. The best training includes scenario-based exercises, role-specific sessions, and the development of “super users” who can provide peer support.
Patient communication also matters: setting expectations about slower service during transition can prevent frustration. Expect 40–80 hours of training per user for a smooth rollout.
4. Go-live and immediate support (2–4 weeks):
The first weeks of go-live determine whether adoption is smooth or chaotic. Reducing patient schedules creates breathing room.
On-site support ensures problems are resolved quickly. Daily debriefs help catch recurring issues before they frustrate staff. Continuous feedback during this period prevents bad workarounds from becoming permanent habits.
Avoiding Common Pitfalls
Despite careful planning, many practices fall into the same traps. Recognizing them early makes them easier to avoid.
- Productivity shock: Most practices experience a 20–30% productivity drop at first. Recovery usually takes 3–6 months, but some never bounce back if optimization is neglected. Planning for this dip, financially and operationally, prevents burnout and financial strain.
- Lack of engagement: If physicians aren’t included in system selection, they may resist adoption. If staff aren’t consulted about workflows, they’ll create workarounds. If patients aren’t warned, they’ll complain about delays. Early and inclusive engagement builds buy-in and smooths resistance.
- Weak change management: Implementation isn’t just technical; it’s cultural. EHRs change workflows, challenge routines, and shift responsibilities. Leaders must guide teams through this adjustment with clear communication, consistent support, and a recognition that change is as much about people as it is about technology.
Implementing an EHR system is less about flipping a switch and more about guiding people through change. Practices that plan carefully, engage stakeholders, and prepare for bumps along the way are the ones that see their EHR become a genuine asset instead of an ongoing burden.
When Standard Systems Fall Short: The Custom Development Option
Even the most carefully chosen EHR system won’t cover every scenario your practice faces. Over time, you may notice gaps between what the software offers and what your workflows actually require.
These gaps don’t mean you picked the wrong system.
They simply reflect the complexity of healthcare and the unique way each organization operates. When that happens, custom development becomes the path to making your EHR truly work for you.
When Standard EHRs Aren’t Enough
You’ll know it’s time to consider custom solutions when everyday tasks start feeling harder than they should. Common situations include:
- Connecting legacy systems that still hold valuable historical data.
- Bridging multiple EHRs during a merger or when joining a larger network.
- Integrating specialized devices that produce unique data types.
- Supporting workflows that give your practice a competitive edge.
In these cases, relying on vendor defaults often creates friction. Off-the-shelf solutions are quicker to implement, but they may force you to adjust your operations to fit the system instead of the other way around. Custom development costs more upfront, but it can save you time, reduce errors, and preserve the workflows that make your practice efficient.
Finding the Right Development Partner
Custom healthcare software isn’t something any developer can build. To avoid compliance risks or workflow mismatches, you need a partner who understands the realities of healthcare. That means looking for expertise in:
- Clinical workflows, so the solution fits how your team actually delivers care.
- Regulations like HIPAA and GDPR, to keep your practice compliant.
- Integration experience, to connect your system with labs, pharmacies, and health information exchanges.
- Healthcare-specific security, to defend against sophisticated threats.

Transforming EHR Challenges into Competitive Advantages
No single EHR system fits every healthcare organization perfectly. Even the best choice leaves gaps that require adaptation and improvement. Success isn’t about finding flawless technology. It’s about understanding your options, making informed decisions, and continually refining the system to support your goals.
Whether you prefer the control of on-premises systems, the convenience of ASP hosting, the flexibility of SaaS, or the full-service support of modern cloud platforms, technology alone won’t guarantee success.
What matters just as much is how you implement it, how you manage change, and how you optimize the system over time. The practices that thrive treat EHR adoption not as the finish line but as the beginning of ongoing transformation.
When standard systems fall short, the gap between vendor capabilities and your operational needs is not a failure. It’s an opportunity. With the right partner, those limitations can be turned into advantages through secure integrations, optimized workflows, and custom solutions that fit your practice.
