Portals help a minority and shine for continuity — an honest compare with a clear ops verdict. [**Norbelys Chirinos** Founder · Product](https://www.getarbol.com/en/blog/authors/norbelys-chirinos/) April 3, 2026 9 min read Americans still book most medical appointments by phone. A 2024–2025 national survey in [Health Affairs Scholar](https://pmc.ncbi.nlm.nih.gov/articles/PMC12086685/) 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. Key takeaways - NCHS estimates about 1.0 billion physician office visits in the US (NAMCS 2019 summary) — most of which require a scheduling step. - Haeder & Xu (2025): 72.1% used phone scheduling in the past year; 56.4% said phone was their primary method; portals were primary for 19.7%. - Ganguli et al. (2020): only 8.1% of portal-enrolled primary care patients adopted direct scheduling — but those visits were more often with their own PCP (95.2% vs 73.5%). - Kachooei et al. (2023): in a large orthopedic group, online vs staff scheduling showed no significant difference in overall no-show rates (4.5% vs 4.4%). ## 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](https://www.cdc.gov/nchs/fastats/physician-visits.htm) 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](https://www.getarbol.com/en/blog/after-hours-calls-practice-cost/) and about [HIPAA-aware voice reminders](https://www.getarbol.com/en/blog/hipaa-voice-appointment-reminders/). This piece answers a narrower question: **portal self-scheduling versus phone scheduling — which evidence should drive the ops decision?** United States — demand and channel mix Visits are huge; phone still leads booking 1.0 B Physician office visits (NAMCS 2019) CDC/NCHS FastStats 72.1% Used phone to schedule in the past year Haeder & Xu 2025 19.7% Portal as primary scheduling method Haeder & Xu 2025 Fuente: CDC/NCHS FastStats; Haeder & Xu, Health Affairs Scholar 2025 ## 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. Primary scheduling method How US adults most often book medical appointments Share of respondents Fuente: Haeder & Xu, Health Affairs Scholar, survey Oct–Nov 2024 ## What portals win when people do use them Ganguli and colleagues studied [direct scheduling in 17 adult primary care practices](https://pmc.ncbi.nlm.nih.gov/articles/PMC7453311/) 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](https://pmc.ncbi.nlm.nih.gov/articles/PMC10199359/) 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. Evidence side by side Portal / online scheduling vs phone / staff scheduling Question Portal / online Phone / staff Share of adults (primary method) 19.7% portal 56.4% phone Adoption among portal-enrolled PC patients 8.1% used direct scheduling Usual path for the rest Continuity with own PCP (when used) 95.2% of direct-scheduled visits 73.5% of staff-scheduled visits No-show (ortho multi-site month) 4.5% 4.4% Best after-hours story Open if portal is live 24/7 Fails unless someone answers Fuente: Haeder & Xu 2025; Ganguli et al. 2020; Kachooei et al. 2023 ## An honest compare — without the vendor fairy tale Channel strengths What each channel is actually good at Provider portal / online self-schedule Strengths Autonomy, off-hours booking, continuity when used “Great for established patients who already live in the portal.” 24/7 booking window Own-PCP continuity Lower routine staff load Phone / staff scheduling Strengths Majority channel, screening, equity of access “Still how most Americans say they book care.” Highest reach Complex routing Works without portal literacy **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](https://www.getarbol.com/en/blog/tcpa-appointment-reminders-compliance/) and HIPAA-safe voice outreach are the second. A portal booking that nobody confirms can DNA as easily as a phone booking. Ops design Treating channels as rivals vs as a stack Either/or Both/and Defund the phone because the portal launched Keep phone capacity; route simple revisits to portal Assume portal users represent all patients Measure primary method mix in your own panel Ignore after-hours rings Answer or call-back nights and weekends on the phone path Stop at booking Confirm on voice/SMS regardless of how the slot was created ## 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. For US practices framing product decisions, [Arbol in the United States](https://www.getarbol.com/en/united-states/) is the market landing for voice-first access and confirmation — complementary to portals, not a speech against them. Specialty caveat Kachooei’s no-show and surgery-progression results come from orthopedics. Subspecialty no-show rates in that paper ranged from roughly 3% to 8%. Do not paste a surgical clinic’s online-scheduling yield onto primary care without measuring your own book. Verdict Keep the portal for autonomy and continuity — but run the practice as if phone is still the primary scheduling system, because for most patients it is. National survey data put phone as the primary method for 56.4% of adults and portals for 19.7%. Portals improve own-PCP continuity among the minority who adopt them; they have not been shown, in the orthopedic evidence above, to beat staff scheduling on no-shows. The winning ops design is a stack: portal for simple self-serve, answered phone (human or agent) for reach and complexity, and shared confirmation after booking. Lean portal-first if… Your panel is highly portal-activated, most demand is routine follow-up with the same clinician, and you can prove phone abandon rates are already low. Lean phone-first (with portal assist) if… You still see majority phone booking, after-hours rings, new-patient complexity, or equity gaps in portal use — the common US primary care pattern. Do not choose “portal only” if… You are using portal launch as a reason to thin phone capacity. The evidence does not support that trade.
