The cadence's largest payoff is the cancer or chronic condition caught while it's still cheap to treat — quiet years where nothing seems to happen, until the year something does. Hearing screening pulls extra weight: untreated hearing loss is the largest fixable mid-life dementia risk we know about. Cost is modest with US insurance, real without it. Effort is mostly the scheduling, not the visits. Done right, this is a few hours a year for the chance to keep the next twenty.
The thing the cadence catches you can't feel. Glaucoma takes peripheral vision before you notice anything is wrong. Melanoma at 1mm has a 99% five-year survival; once it spreads, that number falls below 35% SEER 2024. High blood pressure produces no symptoms for years. Periodontitis hollows out the bone holding your teeth before they get loose. The cadence is a sampling strategy: hit each of these surfaces often enough that the asymptomatic finding lands in a window where the fix is small.
The second piece is friction. Booking each appointment separately, on the year it's due, against your own forgetting and a six-week waitlist — that's where the system fails. A fixed cadence collapses many small decisions into one: pick the month, book the stack, show up. Medicare's Annual Wellness Visit data illustrates the size of this effect cleanly — people who attended received 88% of the screens they were due for, vs. 63% for those who didn't Beckman et al. 2019. The visit barely does anything as an exam; it does a lot as a referral hub.
The third piece is having clinicians who know you. A new mole compared against last year's photo. A blood pressure that's been climbing slowly for three years instead of read in isolation today. A worrying symptom that gets a same-week appointment because you're already on the books, not a six-week wait. The continuity-of-care research finds lower mortality with longer-standing primary-care relationships across multiple cohorts Pereira Gray et al. 2018. The evidence is observational and partly confounded — healthier people stay with one doctor longer — but the mechanism is real and obvious to anyone who's switched doctors at a bad time.
Where the evidence is strong, weak, and contested
The honest version of this is not "go to all your appointments." It's that the appointments vary in what they actually deliver, and conflating them flatters the weak ones and underrates the strong ones.
The standard annual physical, on its own, is the weakest piece. A large body of trial evidence finds it produces no detectable mortality benefit in asymptomatic adults — comparing people offered a yearly comprehensive exam to people who weren't, no difference in cancer deaths, heart deaths, or total deaths.
So the annual visit's value is not the physical exam. It's the cluster of indicated screens — blood pressure, lipids, A1c, depression check, vaccines, age-and-sex-appropriate cancer screening — that happen because someone is sitting across from you with a checklist. The cancer screens are the headline of that cluster: they run on their own age-and-sex timetable, the adult cancer-screening schedule the whole cadence is built to capture.
Dental is the second contested piece. Six-monthly cleanings are custom, not evidence. A British trial in 51 practices and a Cochrane review on dental recall intervals found no measurable difference between six-monthly checkups, two-yearly checkups, and risk-based intervals on cavities, gum disease, or felt wellbeing Clarkson et al. 2020Riley et al. 2020. The American Dental Association now phrases its recommendation as "intervals determined by a dentist" rather than a fixed six months ADA 2024. The right answer for most low-risk adults is a yearly cleaning; for higher-risk mouths (gum disease history, smokers, dry mouth, diabetes) it's six-monthly or quarterly.
The eye exam is the strongest individual piece for adults past 40. Primary open-angle glaucoma destroys peripheral vision silently — by the time a person notices, the lost field is permanent. Diabetic retinopathy, hypertensive retinopathy, and early macular degeneration are the same shape: catchable in a fifteen-minute exam, gone unnoticed otherwise. The American Academy of Ophthalmology grades cadence by age: every 5–10 years under 40, every 2–4 years at 40–54, every 1–3 years at 55–64, every 1–2 years at 65+ AAO 2025. Diabetes drops everyone to annual. The USPSTF gave glaucoma screening an "I" — insufficient evidence — in 2022, on the grounds that no trial has directly compared screening to no screening on visual outcomes USPSTF 2022. The clinical case rests on the asymptomatic-until-late natural history rather than a head-to-head trial.
The skin exam is the most contested piece. The USPSTF concluded in 2023 that there's not enough evidence to recommend routine visual skin examination by a clinician for asymptomatic adults USPSTF 2023. The American Academy of Dermatology pushed back, pointing at the stage-survival cliff: 99% five-year survival when melanoma is caught at 1mm or thinner, under 35% once it has spread SEER 2024AAD 2024. The honest read in the middle: the annual full-body skin exam earns its place for people with personal or family melanoma history, many moles, atypical moles, fair skin with sun damage, or immune suppression. For a 25-year-old with none of those, monthly self-exams plus a single baseline professional check are enough.
Hearing is the dimension most people undercount. The 2020 Lancet Commission on dementia named hearing loss the single largest fixable mid-life risk for later cognitive decline, accounting for about 8% of dementia at the population level Livingston et al. 2020. The ACHIEVE trial in 2023 — three years, older adults at elevated dementia risk — found hearing-aid intervention slowed cognitive decline by about 48% over the trial window Lin et al. 2023. The standard professional guidance is a hearing screen every decade through age 50, then every three years, then yearly past 60 or with noise exposure ASHA 1997. Most adults skip it entirely.
What the absence looks like
The stakes don't show up on any given Tuesday. They show up as slopes you can't see because you weren't taking the measurements.
You're 45. You haven't had an eye exam since you got reading glasses at 40 because your sight feels fine. It is fine. Your peripheral vision has been narrowing for three years, slowly enough that the wider world looks the same at home. The first time you notice is when you pull out of a parking space and clip a car that wasn't there a second ago. The retina specialist names it: glaucoma, the kind that already cost you what it cost you. From here it can be stopped. It can't be undone USPSTF 2022.
You're 52. You skipped the dermatology visit for years because no one in your family had skin cancer and you spent most of your life indoors. The mole on your back, the one your partner kept saying looked weird, turns out to be stage III. It would have been a 15-minute shave biopsy and a single follow-up at the 1mm stage three years earlier SEER 2024. Now it's a year of oncology, a lymph-node dissection, and a survival number you don't want to hear.
You're 58. Your hearing has been going for years and you've adapted around it — turning the TV up, asking people to repeat themselves at dinner, leaving parties early because it's too loud to follow. You start declining the parties. You start declining dinner with friends. The Lancet Commission's accounting calls this the single largest modifiable mid-life risk factor for the cognitive decline that follows Livingston et al. 2020. The ACHIEVE trial says the cognitive cost is not inevitable — that fitting the hearing aid changes the trajectory Lin et al. 2023. But your version of you, ten years from now, won't have caught it in time.
The pattern in each: the visit you'd have skipped because nothing was wrong is exactly the visit that catches the thing. The asymptomatic window is the cadence's whole point.
The cadence, by domain
A defensible default for an average-risk adult. Compress every interval if you have the relevant risk factor.
Operationally: pick one anchor month — birthday month works because it's already pinned in your head — and book the year's stack in one sitting each year. Don't try to remember which one is due when. Calendar reminders fail; one annual scheduling pass works.
Two questions to ask every visit, at every domain. "What am I due for?" Catches the screens the clinician was about to forget. "How are these numbers trending vs. last time?" Catches the slope, not just the snapshot.
What most guides get wrong
"My annual physical covers everything." The annual physical itself, as a comprehensive head-to-toe exam in a healthy adult, doesn't lower mortality — the trial evidence on that is unusually strong Krogsbøll et al. 2019. What the visit does is bring the screens, vaccines, and counselling along with it. Showing up and not asking for those specifically is the failure mode — the visit-as-handshake without the visit-as-referral-hub.
"I have to go to the dentist every six months." The six-month interval is a cultural default, not a trial finding. Risk-tailored intervals — twelve months for low-risk mouths, three to six for high-risk — produce the same outcomes Riley et al. 2020. The American Dental Association now phrases the recommendation that way too ADA 2024.
"My eyes feel fine, so I don't need an exam." The diseases an eye exam catches — glaucoma, diabetic retinopathy, early macular degeneration — are asymptomatic until they aren't. The vision check at the DMV or pharmacy is not the same exam; it doesn't measure eye pressure, doesn't dilate the pupil, doesn't look at the optic nerve USPSTF 2022.
"Hearing loss is something I'll deal with when it happens." By the time you "deal with" it, the cognitive cost may already be running. The Lancet Commission identifies it as the largest modifiable mid-life dementia risk factor we know about, and intervention slows the cognitive decline that follows Livingston et al. 2020Lin et al. 2023. The screen takes ten minutes.
"Skin cancer is a sun-worshipper problem." Indoor-mostly adults still get melanoma; some of the most lethal melanomas appear in places the sun rarely reaches. The risk picture is moles, family history, fair skin, and immune suppression — not just lifetime sun exposure AAD 2024.
The real cost in money and time
In the US with standard insurance, the primary-care annual visit is fully covered as a preventive service under the ACA. Dental and vision usually run as separate plans — a typical dental plan covers two cleanings a year at $0–50 per visit; vision plans cover an exam at $0–30 with frames discounted. Audiology is often out-of-pocket — $0–100 for a screen. Dermatology runs $150–400 uninsured; insured, it's usually a specialist copay around $30–60.
Adding it up: a US adult with comprehensive insurance pays roughly $0–300 a year out-of-pocket for the full stack. Uninsured, it's closer to $500–1,200. The visits themselves run 30–90 minutes each; add waiting-room time and travel, and the year's cadence costs 4–6 hours of life total.
The friction is almost entirely scheduling. Most failures aren't refusal to go; they're "I'll book it next week" stacked seventeen weeks deep. The anchor-month batching is the single highest-leverage move: pick a month, book the full year's appointments at once each year, put each on the calendar before standing up from the chair.
Where this goes wrong
Three patterns.
Skipping the visit that catches nothing. Most years, most visits, nothing happens. The natural conclusion — "I went last year and nothing was wrong; I'll skip this year" — is exactly backwards. The visits that find things are statistically indistinguishable from the ones that don't until you're sitting in the chair. The cadence works because you don't get to pick.
Showing up without a list. The visit's value is the screens that ride on it. If you leave the agenda to the clinician, even good clinicians skip indicated screens — the Medicare Annual Wellness Visit data shows this clearly Beckman et al. 2019. Walk in with: "Which screens am I due for? Which vaccines? Where are my numbers trending?"
Confusing screening with surveillance. If you already have one of the diseases on the catch list — diabetes, glaucoma, melanoma history — the cadence is not enough; you're on surveillance with the relevant specialist, at a tighter interval the specialist sets. The mistake is treating the once-yearly screen as adequate when the diagnosis already exists.
What changes when the cadence is running
Most of the payoff is invisible — the things that didn't happen because something was caught early. The melanoma at 1mm, treated with a 15-minute biopsy and never thought of again, instead of the stage-III version five years later SEER 2024. The glaucoma identified at the first comprehensive exam past 50, treated with drops, vision intact at 80 AAO 2025. The blood pressure noticed at 110/90 instead of 165/110, walked back to baseline with the lifestyle change that still works at that stage.
The visible part is the relationship. After a few years on a cadence with the same clinicians, your dentist remembers the molar that needed watching. Your ophthalmologist has last year's optic-nerve photo to compare against this year's. Your primary-care doctor has the trend on your lipids, not a one-shot number. When you do bring a worrying symptom, you're not starting from zero with a stranger — you're at week one with someone who knows what your normal looks like Pereira Gray et al. 2018.
At 65+, the hearing arm of the cadence carries the largest single payoff anyone can quantify. The 2020 Lancet Commission's accounting of modifiable mid-life dementia risk puts hearing loss at the top of the list, and the ACHIEVE trial in 2023 showed that fitting hearing aids changes the cognitive trajectory in older adults at elevated risk Livingston et al. 2020Lin et al. 2023. The version of you at 75 who can still follow a dinner conversation, still enjoys the noisy restaurant, still tracks the plot of the movie — that version had the hearing screen at 55 and the fitting at 60, while it was still uncomplicated.
The honest summary: the cadence's payoff is mostly the absence of things — a decade with no surprises — punctuated by the one or two years when the routine visit is the reason you're still walking around to have it.
The specific screens that ride on these visits — colonoscopy, mammography, lipid panel, A1c, ApoB, vaccines — have their own entries and their own cadences. Mental-health rhythm (therapy intervals, psychiatric follow-up) sits adjacent to this and is worth its own consideration. If you've already been diagnosed with one of the conditions the cadence is designed to catch, the question shifts from screening to surveillance, with the relevant specialist setting the interval.
- — The five cancer screens are the headline items your yearly cadence is built to capture.
- — The men's 65-year-old aortic ultrasound is one of the once-in-a-lifetime screens worth booking into your cadence.
- — Untreated hearing loss is the biggest fixable dementia risk — fold an audiogram into the cadence.
- — Your annual visits are where the vaccine schedule actually gets executed.
- — The eye doctor is one of the five visits in the cadence — and the baseline exam at 40 is where the silent stuff gets caught.
- — Cervical screening every few years is one of the visits this cadence is built to make sure you don't skip.
- — A week of home readings turns one clinic blood-pressure number into something your checkup can trust.
- — Bring a one-page record to each visit and the year's appointments connect up.
- — The cadence works best with one doctor who knows you across the years.
- — The skin check is the cadence's fifth visit — worth booking with the rest if you've got the risk factors for melanoma.
Substance and claimed effects
The substance is a calendar discipline: the reader books a recurring set of routine preventive visits across five domains — dental cleaning and exam, dermatology skin check, comprehensive eye exam, hearing screening, and primary-care wellness visit — and keeps them on a fixed rhythm. The colloquial "annual everything" is a shorthand; actual guideline-defensible cadences differ by domain and by age. The claimed effects are three: earlier detection of asymptomatic disease (oral cancer, melanoma, glaucoma, hypertension, diabetes, hearing loss, periodontal disease); higher screening adherence for the age-and-sex-indicated tests (colorectal, breast, cervical, lipid, A1c, vaccines) that ride on those visits; and continuity of care — a longitudinal relationship with named clinicians who hold the chart and the history. This entry covers all three, plus the cost / effort honesty about what a five-domain cadence actually costs in time and dollars, and the contested evidence on whether the comprehensive annual physical does anything for asymptomatic adults.
Evidence by addressing question
mechanism — why a cadence matters at all
The mechanism is not biological; it's behavioural and statistical. Three pieces. One, most diseases the cadence catches are asymptomatic in the window where intervention is cheap and effective: primary open-angle glaucoma destroys peripheral vision before the patient notices USPSTF 2022; melanoma in situ has a 5-year survival ~99% but stage-IV survival ~35% SEER 2024; hypertension and pre-diabetes produce no felt symptoms for years. Two, the friction to book each visit individually is what kills adherence — the cadence converts a series of high-friction decisions into one low-friction default. Medicare's Annual Wellness Visit data illustrate the effect: recipients received 88% of indicated preventive services vs. 63% for non-recipients, with the AWV largely functioning as a referral hub rather than a screening test itself Beckman et al. 2019. Three, a stable cadence builds clinician relationships — the longitudinal chart, the noticed trend, the new mole compared to last year's photo. This is the continuity-of-care mechanism, distinct from any single visit's content.
evidence — does each visit actually do something
Primary care annual physical: contested. The 2019 Cochrane review (17 trials, ~250,000 participants) found general health checks have no effect on all-cause, cancer, or cardiovascular mortality (RR 1.00, 95% CI 0.97–1.03), high-certainty evidence Krogsbøll et al. 2019. The USPSTF has not recommended a comprehensive annual physical for asymptomatic adults since the 1980s, favouring risk-stratified preventive services on their own schedules Mehrotra et al. 2007. But the AWV evidence shows the visit as referral hub — even if the exam itself adds little, it dramatically raises uptake of indicated screens, vaccinations, and counselling Beckman et al. 2019. So the annual visit is a behavioural delivery mechanism more than a diagnostic event.
Dental: less than the standard 6-month default, more than nothing. The INTERVAL RCT in 51 UK practices (n=1,736) and the 2020 Cochrane review compared 6-monthly, 24-monthly, and risk-based checkups; no detectable difference in caries, gum disease, or quality of life Clarkson et al. 2020Riley et al. 2020. The ADA itself now phrases the recommendation as "intervals determined by a dentist" rather than universal 6-month ADA 2024. Periodontitis is the highest-yield finding — affects ~40% of adults over 30, mostly asymptomatic until late, and is associated (causally contested) with cardiovascular disease via systemic inflammation Lockhart et al. 2012. Oral cancer screening at routine dental visits has weak evidence for mortality benefit at the population level but is essentially free as a piggyback on the exam.
Eyes: high yield, age-stratified. The AAO's Preferred Practice Pattern explicitly grades cadence by age for asymptomatic adults: every 5–10 years under 40, every 2–4 years at 40–54, every 1–3 years at 55–64, every 1–2 years at 65+ AAO 2025. Annual for diabetes (type 1 from 5 years post-onset, type 2 from diagnosis), family history of glaucoma, or high refractive error. The USPSTF gave glaucoma screening an "I" (insufficient evidence) in 2022 because no RCT has compared population screening to no screening on vision outcomes — but treatment of detected glaucoma does slow progression, and the disease is silent until significant field loss has accrued USPSTF 2022. The AAO's case is opportunistic: the comprehensive exam catches glaucoma, diabetic retinopathy, hypertensive retinopathy, macular degeneration, and refractive change in a single visit.
Dermatology: contested at population level, strong for high-risk. The USPSTF 2023 statement gave visual skin examination by a clinician an "I" recommendation for asymptomatic adolescents and adults without history of premalignant or malignant lesions USPSTF 2023. The AAD pushed back, citing the stage-survival cliff for melanoma — 99% at thin/in-situ vs. 35% at metastatic stage SEER 2024AAD 2024. The honest read: annual dermatology adds little for a low-risk 25-year-old with no family history and no atypical moles; it earns its place for personal melanoma history, family history of melanoma, ≥50 moles, atypical mole syndrome, very fair skin with sun damage, or immunosuppression.
Hearing: not annual. The ASHA protocol is screening every decade through age 50, then every 3 years ASHA 1997. Hearing loss is consequential — the 2020 Lancet Commission identified it as the single largest potentially modifiable midlife risk factor for dementia, ~8% of population-attributable risk Livingston et al. 2020. The ACHIEVE RCT (2023) showed hearing-aid intervention slowed cognitive decline by 48% over 3 years in older adults at elevated dementia risk Lin et al. 2023. So hearing absolutely belongs in the cadence — just not at the same rhythm as the others.
protocol — the defensible default cadence
A reasonable evidence-anchored default for an average-risk adult, organised by domain:
- Dental: cleaning + exam every 6–12 months, set by the dentist's risk read. Low-risk adults can extend to 12–24 months without measurable harm Clarkson et al. 2020.
- Eyes: comprehensive exam every 5–10 years under 40, every 2–4 years at 40–54, every 1–3 years at 55–64, every 1–2 years at 65+, annually with diabetes AAO 2025.
- Dermatology: annual full-skin exam if any risk factor (personal/family melanoma history, ≥50 moles, atypical moles, fair skin with sun damage, immunosuppression); monthly self-exams plus a baseline professional exam otherwise USPSTF 2023AAD 2024.
- Hearing: screening every 10 years through age 50, every 3 years after, annually after 60 or with noise exposure or any reported difficulty ASHA 1997.
- Primary care: annual wellness visit (Medicare covers this from age 65) for the referral-hub effect, even if the exam itself is low-yield Beckman et al. 2019Krogsbøll et al. 2019.
The operational practice: pick one anchor month (often birthday month) and stack the year's visits into a single planning pass — book all five at once each January. The cost of forgetting is exactly the kind of attrition the cadence exists to defeat.
contraindications — when this changes
Pregnancy raises the dental priority (gingival changes; some advise an early-pregnancy cleaning) and modifies the dermatology read (melanocytic changes). Active treatment for any of the catchable conditions (diabetes, hypertension, glaucoma, melanoma history) replaces the screening cadence with a surveillance cadence — typically annual or more frequent at the relevant specialist, set by the treating clinician. Immunosuppression (transplant, long-term steroids, biologics) shifts dermatology to every 6 months. None of these are reasons to skip the cadence; they're reasons to tighten it.
misconceptions — what most people get wrong
Four:
- "Annual physical = annual screening." The annual physical itself is low-yield Krogsbøll et al. 2019; its value is the referral hub Beckman et al. 2019. Conflating the two leads people to think they're "covered" because they showed up.
- "Six-monthly dental is non-negotiable." The 6-month interval is custom, not evidence — the Cochrane evidence supports tailoring to risk Riley et al. 2020. Two-yearly is fine for genuinely low-risk adults; six-monthly is right for high-risk.
- "If I can see fine I don't need an eye exam." Glaucoma, diabetic retinopathy, and macular degeneration are asymptomatic well into significant damage USPSTF 2022. Vision-test-only at the DMV or pharmacy is not a comprehensive exam.
- "Hearing loss is an old-person problem to deal with later." It's the largest modifiable midlife dementia risk factor in the 2020 Lancet Commission's accounting Livingston et al. 2020; intervention slows cognitive decline Lin et al. 2023.
practicalities — what the cadence actually costs
Cost in the US with reasonable insurance: dental cleaning + exam $0–150 per visit covered, full uncovered cleaning $150–300; comprehensive eye exam $100–250 uncovered; full-skin dermatology exam $150–400 uncovered; audiology screening $0–100; PCP annual visit covered by ACA preventive provisions. Adding it up for an average-risk uninsured adult: roughly $500–1,200/year for a full five-domain cadence; for an insured adult, often near zero out-of-pocket if all in-network. Time cost: about 4–6 hours of appointments + waiting-room time across the year. The friction is mostly scheduling. The single highest-leverage operational move is batching all bookings into one anchor month.
failure-modes — where this falls apart
Three common failures: (a) skipping the visit you "don't need" because nothing's wrong — exactly the visit that catches the asymptomatic finding; (b) showing up and not asking for the screens you're due for (clinicians miss them too, especially during AWVs Beckman et al. 2019); (c) swapping the comprehensive eye exam for a pharmacy vision test or "how's your sight?" at the PCP — neither catches glaucoma or retinopathy.
stakes — what the absence looks like
Compounding asymptomatic disease. The 40-year-old who skips eyes until 55 may show up with established glaucomatous field loss that can't be reversed, only halted. The mole that would have been a 1mm shave biopsy at 45 becomes a stage-III melanoma at 52. The periodontitis that compounds quietly into bone loss and tooth loss at 60. The hearing loss that goes uncorrected for a decade and shows up as social withdrawal, then accelerated cognitive decline Livingston et al. 2020. None of these are dramatic events on a given Tuesday — they're slopes, and the cadence is what samples the slope often enough to act on it.
payoff — what shows up when this is in place
The cadence's payoff is mostly invisible — the cancer not diagnosed late, the glaucoma caught in time, the hearing aid fitted at 58 instead of 68. Visible payoffs: known numbers (BP, lipids, A1c, IOP, hearing thresholds) that let the reader and their clinicians notice trends; established relationships that mean a worrying symptom in five years gets a same-week appointment, not a six-week waitlist; vaccines and screens up to date by default. At 65+, the most concrete payoff is dementia-risk modification via the hearing arm of the cadence Lin et al. 2023.
out-of-scope — adjacent topics
Specific screens (colonoscopy, mammography, ApoB / lipid panel, A1c) ride on these visits but are scored as their own entries. Specialty surveillance (cardiology, gastroenterology, endocrinology) is condition-driven, not a default cadence. Mental health check-ins are a real adjacent rhythm but not part of the conventional five-domain default.
The credibility range
Optimist case
The annual cadence is one of the highest-leverage behavioural interventions a working-age adult has. The diseases it catches are asymptomatic until late and dramatically more treatable early — glaucoma, melanoma, periodontitis, diabetic retinopathy, hypertension, hearing-related cognitive risk. The Medicare AWV data shows visits drive screening uptake even when the exam itself is low-yield Beckman et al. 2019. The continuity-of-care literature shows lower mortality with higher continuity across multiple studies Pereira Gray et al. 2018. Hearing intervention in older adults at elevated dementia risk slows cognitive decline ~48% over 3 years Lin et al. 2023. The upfront cost (a few hours and, often, $0 out of pocket on US ACA-compliant insurance) is trivial against the downside of late-stage detection. Even the contested annual physical earns its place as a referral hub.
Skeptic case
The Cochrane evidence on general health checks is unambiguous: no mortality benefit, high certainty, ~250,000 participants Krogsbøll et al. 2019. The USPSTF gives "I" (insufficient evidence) to glaucoma USPSTF 2022 and to clinician skin examination USPSTF 2023; six-monthly dental has been overturned in trials Clarkson et al. 2020. Routine screening of asymptomatic populations produces well-documented harms: overdiagnosis, false positives, biopsy cascades, anxiety, costs that crowd out higher-value care. The continuity-of-care association is observational and confounded — healthier and more engaged patients self-select into continuity. Much of the cadence is custom and commerce, not evidence — dentistry's 6-month default originated as a 1950s toothpaste-ad slogan, not a trial finding.
Author's call
The cadence is real but not the strawman version. The honest entry rejects "annual everything" as both the prescribed default and the strawman to dismiss. The defensible cadence is: dental every 6–12 months on dentist-set risk; eyes on the AAO age-graded ladder, annually with diabetes; dermatology annually only with risk factors, monthly self-exam otherwise; hearing on the ASHA decade-then-3-year schedule, annually after 60; primary care annually for the referral-hub effect even though the exam itself is low-yield. Evidence rating ~3 — the individual screens range from strong (some) to insufficient (others), but the practice of keeping a cadence earns its place via the screening-adherence and continuity mechanisms even where the exams themselves are low-yield. Controversy ~3 — guideline bodies actively disagree on the comprehensive physical and on clinician skin examination, and the 6-month dental default has been falsified.
Stakeholder and incentive map
- Commercial: dental practices (visit volume), private optometry chains, dermatology practices, hearing-aid manufacturers and dispensers, insurers (variable — preventive visits are usually covered as a cost-control measure on downstream disease).
- Professional: ADA, AAO, AOA, AAD, ASHA, AAFP — generally push more frequent visits than the strongest evidence supports; this is mostly genuine clinical conservatism, partly guild interest.
- Skeptic / counter: USPSTF (evidence-strict, often gives "I" or "D" recommendations against routine screening); Choosing Wisely campaigns at specialty societies that have explicitly recommended against the comprehensive annual physical for low-risk adults; the Cochrane Collaboration on dental recall intervals and general health checks.
- Cultural: the "annual physical" is a cultural artefact, deeply embedded in HR benefit design, employer wellness programmes, and patient expectation — independent of the evidence.
Population variability
- Age dominates the cadence. The schedule for a 25-year-old (eyes every 5–10 years, hearing every decade, dermatology by self-exam) is materially different from a 65-year-old (eyes every 1–2 years, hearing every 1–3 years, full-skin annual if any risk).
- Risk-factor presence compresses every interval: diabetes → annual eye exam; melanoma family history → annual full-skin exam; periodontitis history → quarterly dental; first-degree glaucoma → annual eye exam from 40.
- Race / ethnicity shifts the eye schedule: primary open-angle glaucoma is materially more common in Black and Latino/Hispanic adults; the AAO recommends earlier and more frequent exams AAO 2025.
- Access is the real variability driver in the US: ACA preventive coverage gets most of the cadence to $0 out-of-pocket for insured adults, but dental and vision are typically not bundled, and the uninsured face the full price tag.
- Existing diagnosis replaces screening cadence with surveillance cadence — managed by the treating clinician, not the default rhythm.
Knowledge gaps
The biggest gap is the absence of RCTs on screening cadence as a behavioural intervention — virtually all the trial evidence is on individual screening tests, not the practice of holding a calendar. The Krogsbøll Cochrane review tests the comprehensive physical as a screening event, not the visit-as-referral-hub effect that the Beckman data on the Medicare AWV suggests is the real mechanism Krogsbøll et al. 2019Beckman et al. 2019. The continuity-of-care literature is observational and would benefit from a stronger causal design. The dermatology literature is missing the high-risk-stratified RCT that would resolve the USPSTF / AAD disagreement USPSTF 2023. The dental six-month default has been falsified for low-risk adults but the risk-stratified protocols vary widely between practices and aren't standardised Clarkson et al. 2020.
Narrowing vs. the brief. The brief named "scheduling defaults for routine adult preventive visits across dental, dermatology, eyes, ears, and primary care" plus three consequences: early detection, screening adherence, and continuity of care. The article covers all five domains and all three consequences end-to-end. No silent narrowing.
The contested-evidence framing was deliberate. The honest read of the literature — strong Cochrane evidence against the comprehensive annual physical as a mortality intervention, USPSTF "I" ratings on clinician skin exams and on glaucoma screening, falsification of six-month dental — is in real tension with the cultural / professional default of "annual everything." We chose to surface the tension rather than launder it. The cadence still earns its place via the referral-hub mechanism, the asymptomatic-disease catch surfaces, and the hearing-arm dementia evidence; the article makes that case without overclaiming the individual screens.
Hard scoring calls. longevity at 3 (not 4) because the trial-strong piece is the visit-as-referral-hub, not the cadence itself; the Cochrane mortality null result kept it from going higher. focus at 2 leans almost entirely on the hearing arm — without ACHIEVE and Livingston 2020 it would be 0 or 1. energy set to 0 because the cadence doesn't move daily vitality unless it catches one of a handful of conditions (thyroid, anemia, sleep apnea); the indirect path isn't strong enough to score. controversy at 3 because guideline bodies actively disagree, not just at the margins.
Audience scoping. Considered narrowing to adults ages 40+ where the eye and dermatology arms get teeth. Rejected: hearing screening cadence applies from young adulthood, and dental and primary-care cadences apply throughout adulthood. The age-stratified content lives inside the protocol section rather than in audience meta.
Future-link candidates. Sibling entries for the individual screens — colonoscopy / mammography / lipid panel / A1c / ApoB / shingles vaccine — should cross-link here when they exist. A mental-health-rhythm entry (therapy and psychiatric cadence) is the closest adjacent topic that wasn't covered.
Separate-entry candidates surfaced. Hearing screening and dementia risk warrants its own entry given the ACHIEVE / Livingston evidence and how undercovered it is in lay material. Periodontitis as cardiovascular risk is another — the inflammation-CVD association is real but causally contested and deserves more than the one-line treatment it gets here. The Medicare Annual Wellness Visit as referral hub is potentially its own piece for the 65+ audience.
What we left out and why. Pediatric and adolescent preventive cadences (the well-child schedule) are a different system and out of scope here. Specialty-driven surveillance schedules for diagnosed conditions are mentioned but not detailed — they're managed by the treating clinician, not a default. Specific blood-test panels and what to ask for are flagged toward the screens' own future entries. Pregnancy modifies several cadences (dental priority, dermatology read) — mentioned but not unpacked because the broader prenatal-care entry would carry that detail.
Geography. Cost figures are US-anchored — the ACA framing, dental and vision as separate plans, audiology often out-of-pocket. A non-US reader gets the cadence guidance but the cost numbers in practicalities would need re-anchoring per locale at translation.
The Annual Preventive-Exam Cadence
A few hundred to about $1,200 a year if you're uninsured. With normal US insurance, often near zero for the doctor visits, with some copay for dental and eyes.
The hard part is the booking, not the visits. Pick one month a year, book everything at once, then show up — four to six hours total spread across the year.
The cancer found at a routine skin check. The glaucoma caught while you can still treat it. The blood pressure noticed before the stroke. This is where the cadence earns its keep.
Strong on some pieces — the hearing-and-thinking link, the dental risk-based rhythm. Weaker on others — the full annual physical, the routine skin check on low-risk adults.
Keeping your teeth and catching sun damage early add up over decades. The people whose faces and smiles age well usually had this rhythm running quietly.
Hearing loss is the biggest fixable mid-life dementia risk we know about. A few minutes of testing every few years buys decades of clearer thinking.
A dental cleaning leaves your teeth visibly cleaner for a week. A skin check can catch the acne or sun-spot you'd otherwise live with. Small, not the headline.
Most visits, you walk out feeling the same. The change comes the year a visit catches what was draining you — high blood pressure, low iron, an under-treated thyroid.
Depression and anxiety often surface first on the routine screen at your yearly visit. Treatment that starts here is quiet but real.
