Patient Portal Adoption: From 19% to 72% Case Study 2026

Key Takeaways

• Suburban Atlanta multi-specialty practice (12 providers, 18,400 active patients) increased portal adoption from 19% to 72% in 5 months using automated onboarding workflows — adding 9,752 active portal users

• Phone call volume dropped 41% (from 1,840 to 1,086 calls per week) within 90 days of reaching 50% portal adoption, saving approximately $196,000 in annual front desk labor costs, consistent with MGMA benchmarks

• According to ONC, the national average portal adoption rate is 25-30% — this practice now operates in the top 8% of all US practices for portal engagement

• Lab result delivery time decreased from 3.4 days average (phone-based) to 1.8 hours (auto-release to portal), eliminating 340 weekly "where are my results?" calls according to practice call log data

• MIPS Promoting Interoperability score improved from 62/100 to 94/100, protecting $168,000 in annual Medicare reimbursement from potential payment adjustments according to CMS QPP scoring methodology

Practice Profile: Before Automation

Peachtree Multi-Specialty Associates (name changed for privacy) operates three locations across suburban Atlanta serving a diverse patient population. The practice includes family medicine, internal medicine, cardiology, endocrinology, and orthopedics.

The practice manager described the situation: "We activated the athenahealth portal three years ago. We put table tents in every exam room. We printed flyers. Our providers were supposed to mention it. But we never built a system around it. It was always 'when we get time' — and we never got time."

According to MGMA's 2025 Practice Operations Report, this profile is typical. Practices that rely on passive portal promotion (flyers, verbal reminders, portal links on websites) achieve 15-25% adoption. Practices that implement active, automated promotion achieve 60-75%.

Why do patients not sign up for portals despite provider recommendations? According to Pew Research Center, the top barriers cited by patients are: "I forgot by the time I got home" (38%), "I didn't understand what it does for me" (27%), "The signup process was confusing" (19%), and "I prefer calling the office" (16%). Notice that none of these barriers are insurmountable — they are all addressable through automation and clear messaging.

The Problem: Manual Portal Promotion at Scale

The practice's existing portal promotion workflow:

1. Front desk receptionist mentions the portal during check-in (average 8 seconds of conversation)

2. Paper flyer with portal URL placed in the checkout folder

3. Providers occasionally mention the portal during visits (estimated 30% of visits)

4. Practice website has a "Patient Portal" link in the navigation

5. No follow-up after the visit for patients who did not enroll

According to KLAS Research, verbal portal recommendations during check-in convert at 3-5%. Paper flyers convert at 1-2%. Website links convert at 0.5-1%. The total conversion from all passive channels combined rarely exceeds 8% of unenrolled patients per month — meaning that at 18,400 patients and 19% adoption, the practice was adding approximately 120 new portal users per month at its passive pace.

The math was discouraging. At 120 new users per month, reaching 70% adoption (12,880 users) from the existing base of 3,496 would take 78 months — over six years. The practice needed to compress that timeline to under six months.

The Automation Solution

Working with US Tech Automations, the practice implemented a five-phase portal adoption automation program integrated with their athenahealth EHR.

Phase 1: Pre-Visit Enrollment (Weeks 1-4)

The first automation targeted the highest-intent moment — the period between scheduling and the appointment.

Results after 4 weeks: Pre-visit enrollment converted 22% of unenrolled patients with upcoming appointments. The practice added 1,840 new portal accounts in the first month alone — 15x the previous monthly rate.

According to Phreesia's 2025 patient access benchmarks, pre-visit digital enrollment is the single highest-converting portal adoption channel, with 18-28% conversion rates depending on message quality and timing.

Phase 2: Result-Triggered Activation (Weeks 3-8)

The second automation targeted patients who had portal accounts but had never logged in — the "dormant account" segment.

How do you get patients to actually use the portal after signing up? According to ONC, the most effective activation trigger is sending patients a notification that specific content is waiting for them in the portal. Generic "check your portal" messages convert at 4%. Messages referencing a specific lab result convert at 31%. Messages referencing a specific visit summary convert at 22%.

The practice configured automatic notifications when:

• Lab results posted to the portal (sent within 30 minutes of result finalization)

• Visit summaries posted after appointments

• Referral information was added to the chart

• Prescription refill confirmations were processed

Results: Of 3,200 patients with dormant accounts, 1,856 (58%) logged in for the first time within 6 weeks. Lab result notifications drove 72% of these activations.

Phase 3: Engagement Drip Sequences (Weeks 5-12)

After first login, patients entered a 30-day automated education sequence.

According to Relatient's 2025 patient engagement data, patients who use 3+ portal features in their first 30 days show 78% retention at 12 months. Patients who only view lab results show 23% retention. The drip sequence was designed to push patients past the single-feature threshold.

According to MGMA, the average practice spends $0 on portal engagement after initial enrollment. Practices in the top quartile for portal adoption spend $0.85-$1.20 per patient per year on automated engagement messaging. For a practice with 18,400 patients, that is $15,640-$22,080 annually — a fraction of the phone call savings generated by higher portal usage.

Phase 4: Demographic-Targeted Campaigns (Weeks 8-16)

Analytics from the first two months revealed adoption gaps by demographic segment. The practice deployed targeted automation for underperforming groups.

According to ONC, the 65+ demographic is the fastest-growing segment for portal adoption when proxy accounts are made easy. The practice implemented a streamlined proxy enrollment process where adult children could enroll as authorized representatives during a single phone call — taking proxy accounts from 3% to 18% of all accounts in the 65+ segment.

Phase 5: Re-engagement Automation (Ongoing)

For patients inactive for 60+ days, the system triggers re-engagement tied to upcoming clinical events.

US Tech Automations built these re-engagement workflows to fire automatically based on scheduling data, care gap alerts, and prescription renewal cycles — ensuring that the portal stays relevant to each patient's care journey.

Practices that have also implemented medical appointment reminder automation find that portal adoption and appointment adherence reinforce each other — patients using the portal show 34% lower no-show rates, according to Relatient data.

Results: 5-Month Outcomes

According to CMS 2026 QPP scoring data, a MIPS Promoting Interoperability score increase from 62 to 94 translates to approximately 15-20 additional composite performance score points. For this practice billing $1.87 million in Medicare annually, protecting against the maximum -9% payment adjustment preserves $168,000 in revenue.

Financial Analysis

According to MGMA, the median ROI timeline for portal adoption automation is 4-6 months to breakeven when accounting for reduced call volume as the primary savings driver. This practice reached breakeven at month 3.5 based on the immediate phone volume reduction following the pre-visit enrollment campaign.

Lessons Learned

Lesson 1: Lead with specific value, not generic promotion. The practice's previous approach ("Sign up for your patient portal!") converted at 3%. The automated approach ("Your lab results from today are ready — view them now") converted at 31%. According to KLAS Research, specificity is the single strongest predictor of portal enrollment conversion.

Lesson 2: The 65+ population responds to proxy enrollment. The practice initially wrote off patients over 65 as "not tech-savvy." After implementing proxy enrollment for adult children, the 65+ segment reached 52% adoption — well above the 18% national average for this age group, according to ONC.

Lesson 3: Portal adoption compounds. According to the practice manager, the most unexpected result was that patients who adopted the portal started requesting fewer phone callbacks overall — not just for the functions available in the portal. Patients who could message their care team felt less anxious about pending issues and were less likely to call for status updates on referrals, prior authorizations, and other processes.

Practices implementing prescription refill automation alongside portal adoption see compounding benefits — portal-based refill requests are 74% faster to process than phone-based requests, and patients who discover refill functionality through the portal engagement drip become habitual portal users.

Lesson 4: Automation requires monitoring, not management. The practice designated one staff member (2 hours per week) to review portal adoption dashboards and adjust messaging for underperforming segments. This is not a "set it and forget it" system — but it is dramatically less labor than manual promotion. US Tech Automations provides weekly automated reports flagging segments that need attention.

For practices also working on patient follow-up automation, portal adoption provides the delivery channel that makes follow-up workflows scalable. Follow-up messages through the portal cost $0 per message versus $0.08-$0.15 per SMS and $2.50-$4.00 per phone call.

Frequently Asked Questions

Can these results be replicated at a smaller practice?

Practices with 3-5 providers and 4,000-8,000 active patients achieve similar percentage improvements with proportionally lower absolute numbers. According to MGMA benchmarking, smaller practices often reach 70% adoption faster because they have fewer total patients to enroll and more personal provider-patient relationships that drive trust in the portal. A 5-provider family medicine practice implementing the same automation workflow reached 68% adoption in 4 months.

What EHR systems support this level of automation?

This case study used athenahealth, but the automation workflows are EHR-agnostic. The enrollment triggers, messaging sequences, and engagement tracking operate through the automation platform — not through the EHR directly. According to KLAS Research, the most automation-friendly EHR portals are Epic MyChart, athenahealth, and eClinicalWorks, but practices on NextGen, Allscripts, and Greenway have achieved similar results with API-based integration.

How did the practice handle patients who actively refused the portal?

Approximately 12% of patients explicitly declined portal enrollment during the pre-visit SMS outreach. The practice coded these patients as "portal declined" and excluded them from future enrollment automation. According to ONC, 8-15% of patients across all demographics consistently prefer phone-based communication. The practice maintained phone-based workflows for this segment while reducing the overall call volume burden through the 72% that adopted the portal.

What was the staff reaction to the automation rollout?

According to the practice manager, front desk staff were initially concerned about job elimination. The practice reframed the initiative: "We're not reducing staff — we're redirecting staff from answering phones to patient experience." Two of the 2.5 reduced FTEs were natural attrition (staff who left and were not replaced). The remaining 0.5 FTE was a part-time position that converted to a "digital navigator" role helping patients with portal adoption in the office.

How does portal adoption affect patient retention?

According to athenahealth's 2025 benchmarking data, patients with active portal accounts show 23% higher retention rates than patients without portal accounts. The hypothesized mechanism is that portal usage creates switching costs — patients invested in their health records, messaging relationships, and medication history within the portal are less likely to change practices. For this practice, 12-month patient retention improved from 81% to 89% after portal adoption reached 70%.

What happens if the portal vendor changes or upgrades?

This is a legitimate concern. According to KLAS Research, major EHR portal redesigns occur every 3-5 years, and each redesign temporarily reduces engagement as patients relearn the interface. The automation layer (enrollment and engagement workflows) is vendor-independent — if the practice switched from athenahealth to Epic, the automation sequences would reconnect to the new portal. The investment in automation workflows is not locked to any single portal platform.

Does portal adoption reduce malpractice risk?

According to the American Medical Association, documented patient communication through portal messaging creates a discoverable record that can support malpractice defense. Practices with high portal adoption have clearer documentation of patient education, result notification, and care instructions. While no direct malpractice premium reduction has been tied to portal adoption alone, several major malpractice carriers have begun offering risk management credits for practices demonstrating systematic patient communication workflows.
