Portal vs phone scheduling: what US practices should actually choose

Americans still book most medical appointments by phone. A 2024–2025 national survey in Health Affairs Scholar found 72.1% of adults had used the phone to schedule in the past year, and 56.4% said phone was their primary method — versus 19.7% whose primary method was a provider portal. Portals are real and useful, especially for continuity. They are not, on current evidence, the majority channel. The honest compare is not “portal good, phone bad.” It is which jobs each channel wins — and how a practice covers both without pretending one erased the other.

The scale of the scheduling problem is national

Before choosing a channel strategy, sit with the volume. CDC’s NCHS FastStats on physician office visits reports 1.0 billion visits, 320.7 visits per 100 persons, and 50.3% of visits made to primary care physicians (National Ambulatory Medical Care Survey: 2019 National Summary Tables). Haeder and Xu open their research letter with the same order of magnitude: more than a billion outpatient office visits a year, nearly all requiring someone to schedule.

That scheduling step is where access is won or lost — including after hours, when the portal may be open but the phone goes to voicemail. We have already written about the cost of after-hours calls and about HIPAA-aware voice reminders. This piece answers a narrower question: portal self-scheduling versus phone scheduling — which evidence should drive the ops decision?

What patients actually use: phone first, portal second

Haeder and Xu fielded a quota-sampled US adult survey (16 October–7 November 2024; 3,661 completes after attention checks; weighted to Census benchmarks). Respondents could select multiple methods used in the past year, then name a primary method.

Used at least once in the past year:

• Phone: 72.1% (95% CI 70.3–73.9%)
• In-person at the office: 40.6% (38.7–42.7%)
• Provider portal: 34.1% (32.2–36.1%)
• Third-party scheduling apps: 4.3% (3.5–5.2%)

Primary method:

• Phone: 56.4% (54.4–58.4%)
• Provider portal: 19.7% (18.1–21.3%)
• In-office: 19.1% (17.5–20.7%)
• Third-party / other: about 2% each

That is the national picture: portals matter, phone dominates. Any strategy that starves the phone line because “we have a portal now” is arguing with how people actually book.

What portals win when people do use them

Ganguli and colleagues studied direct scheduling in 17 adult primary care practices at a large Boston academic system (March 2018–March 2019): 134,225 completed visits by 62,080 portal-enrolled patients attributed to 140 PCPs.

Adoption of direct scheduling — at least one use in the study year — was only 8.1% (5,020 patients). Adopters skewed younger, more often White, commercially insured, and with more comorbidities than nonadopters in the same practices. But when they did book online, the continuity signal was strong:

• Directly scheduled visits were more often general medical examinations (36.7% vs 21.9% of usually scheduled visits).
• They were far more often with the patient’s own PCP (95.2% vs 73.5%).

So portals, in this primary care setting, were a minority behavior with a majority payoff for continuity among adopters. That is a real win — and a reminder that “portal available” is not “portal used.”

Does online scheduling change no-shows or clinical yield?

Kachooei and colleagues compared web-based online scheduling vs traditional staff scheduling across a multi-subspecialty orthopedic practice in PA, NJ, and NY for February 2022: 71,673 traditionally scheduled and 3,058 online-scheduled visits.

Headline results:

• Progression to any procedure within 3 months: 21% in both groups (P = 0.97).
• Progression to surgery within 3 months: 18% in both groups (P = 0.88).
• Among new visits only, traditional scheduling had a higher surgery progression rate (21% vs 18%, P = 0.036).
• No-show rates: 4.5% online vs 4.4% traditional (P = 0.79) — not significant.
• No-show rates did differ by subspecialty (P < 0.001), from about 3% (joint replacement; foot and ankle) to 8% (trauma).

Read carefully: online scheduling did not magically reduce no-shows in this surgical specialty setting, and it did not hurt overall procedure yield. For new surgical consults, staff scheduling still edged surgery progression — possibly reflecting screening conversations that online algorithms only partly replicate. The authors still argue for offering online scheduling for autonomy and staff burden; they do not claim it replaces the phone.

An honest compare — without the vendor fairy tale

Portal weaknesses the evidence implies: low adoption even among enrolled patients; demographic skew; weak coverage of people who never activate the portal; no automatic fix for no-shows.

Phone weaknesses practices already feel: hold times, limited hours, abandoned calls, staff burnout — especially after hours (see the after-hours cost piece). Phone is the majority channel and the majority operational headache.

Neither channel, alone, solves confirmation and reminder compliance. Scheduling is only the first mile; TCPA-aware reminder design and HIPAA-safe voice outreach are the second. A portal booking that nobody confirms can DNA as easily as a phone booking.

What your practice can do with this compare

1. 1
   Instrument both funnels

   Count completed bookings, abandons, and no-shows by scheduling source — portal, phone, in-office — monthly.

2. 2
   Push portal for the jobs it wins

   Routine follow-ups and own-PCP exams for already-enrolled patients; celebrate the continuity gain Ganguli measured.

3. 3
   Staff (or agent) the phone like the majority channel it is

   Haeder’s 56.4% primary-method figure is your planning assumption until your own survey says otherwise.

4. 4
   Cover after-hours on the phone path

   Portal hours do not excuse a dead line; that gap is a cost center of its own.

5. 5
   Confirm every booking the same way

   Source-agnostic reminders beat arguing about which channel “owns” no-show reduction.
