Research report
A research report is the sourced material a domain
dossier is synthesized from — generated on a plan and a cadence, one topic per file.
A report carries no confidence tags. Its bracketed markers say who might have
an incentive to shade a line; none of them says anyone checked it. To reach a score, a line has
to be drafted onto a candidate as unverified and pass the Verifier or the
Corroborator, like everything else.

The domain dossier's Section 2 (care pathway) flagged three specific gaps: who performs the triage before a PSG bed is used, where PSG capacity physically sits, and a US-specific quantified access figure — this report closes part of each. A 469-child pediatric OSA clinic cohort shows what is already in the room before a sleep study is ever ordered: a parent-completed questionnaire, an overnight pulse oximeter, and a clinician's tonsil-grading exam, feeding a triage algorithm that routes children either to otolaryngology or to a sleep specialist [1]. A retrospective cohort at one US tertiary children's hospital supplies the US-specific quantified access figure the dossier could not find: rural-dwelling children had a 30% lower adjusted hazard of receiving adenotonsillectomy over time than urban-dwelling children, with a median driving distance of 74.8 versus 16.8 miles [2]. One actively recruiting US trial names its site of service explicitly — the Children's Hospital of Philadelphia Sleep Laboratory, the point of referral for children already flagged for diagnostic PSG "as part of clinical care" [3]. A 2012 AAP technical report adds a treatment-side site-of-service detail the dossier did not carry: some children require inpatient observation after adenotonsillectomy for postoperative intubation or CPAP, and CPAP itself is limited as first-line therapy by adherence [4]. Telehealth and home-testing alternatives to the in-person/in-lab pathway exist in the literature but remain reviews and recommendations, not measured pediatric outcomes [5][6].
_Baseline (v1). No prior version; this establishes the starting point for future diffs._
A 469-child cohort from a pediatric OSA clinic (country/institution not stated in the retrieved abstract; published in a Canadian-affiliated otolaryngology journal, so not assumed US here) describes the equipment and staff already present at the triage step, well before a sleep laboratory is involved: parents complete the Pediatric Sleep Questionnaire (PSQ) plus screening questions for restless leg syndrome, rhinitis and GERD; a clinician grades tonsil size on the Brodsky five-point scale from the chart; and the child completes an overnight pulse-oximetry study, scored as a McGill Oximetry Score, before ever being seen in clinic [1][single-source]. The study's own triage algorithm, generated from logistic regression on this cohort, found tonsil size alone the strongest predictor of adenotonsillectomy — an odds ratio of 9.11 (sensitivity 0.72, specificity 0.78) — and recommended that referral letters for snoring children include graded tonsil size, with children graded "2+" tonsils routed to otolaryngology and the remainder to a pediatric sleep specialist [1][single-source]. A separate narrative review of the pediatric dentistry literature (ten included studies, structured per the SANRA scale) adds a room the dossier had not named at all: pediatric dentists and orthodontists, in routine contact with children, are described as contributing to "screening through recognition of clinical signs and symptoms, use of validated questionnaires, and identification of craniofacial and occlusal features," and to "timely referral" into the same otolaryngology/sleep-specialist pathway [5][single-source].
One actively recruiting US trial states its site of service in its own eligibility criteria: children must be "referred for diagnostic PSG at the Children's Hospital of Philadelphia (CHOP) Sleep Laboratory for evaluation of OSA as part of clinical care" before they can be randomized to compare home testing against it [3][single-source]. That single-institution detail is consistent with the dossier's existing description of PSG as hospital-anchored, but it is one recruiting trial's own site, not a survey of where pediatric PSG capacity sits nationally. Distance to that kind of site matters: a retrospective cohort of 213 children recommended for tonsillectomy with or without adenoidectomy at one US tertiary children's hospital (April 2016–December 2018) found rural-dwelling children (32% of the cohort) had a median driving distance of 74.8 miles versus 16.8 miles for urban-dwelling children (p<.001), were more often insured by Medicaid than private insurance (p<.001), and — after adjusting for age, sex, insurance and race — had a 30% lower hazard of receiving the recommended surgery over time (HR 0.7, 95% CI 0.50–0.99), despite 94.9% of the full cohort eventually undergoing surgery once evaluated by an otolaryngologist [2][single-source]. This is the US, quantified figure the dossier's own Section 2/5 recorded as "not found"; it measures surgical follow-through rather than PSG wait time specifically, so it narrows, but does not close, that gap.
The 2012 AAP technical report underlying the standing pediatric OSA guideline states that adenotonsillectomy is the primary treatment, but adds a detail the dossier's existing citation of this same source did not carry forward: "a significant number of obese patients required intubation or continuous positive airway pressure (CPAP) postoperatively, which reinforces the need for inpatient observation" — i.e., same-day ambulatory discharge is not the default site of service for every child having this surgery. The same report states CPAP "is not recommended as first-line therapy for OSAS when AT is an option" because "adherence is a major barrier" [4][single-source]. Residual OSAS after adenotonsillectomy, per the same technical report, "ranged from 13% to 29% in low-risk populations to 73% when obese children were included and stricter polysomnographic criteria were used" [4][single-source] — a population for whom the care pathway does not end at surgery.
A review of telemedicine in pediatric sleep medicine states that "prior to the COVID-19 pandemic, few pediatric sleep medicine clinicians routinely engaged in telemedicine visits because thorough examinations were difficult to perform; there was lack of consistent reimbursement; and many clinicians were busy with their in-office practices," and describes current applications and challenges without reporting a pediatric outcome of its own [6][single-source]. A structured MEDLINE review of 16 articles on paediatric domiciliary sleep studies reports that "home-based polysomnography (level 2) has high feasibility and parental preference" while "simpler modalities like pulse oximetry and level 4 approaches often underdiagnose OSA," and its implementation recommendations include "minimising equipment complexity" and "involving trained technicians or providing thorough parental education" — naming the staffing/training question a limited-channel home device would still have to answer, without answering it for any specific device [7][single-source].

Well established: Nothing in this report rests on two independent, non-affiliated sources for the same specific finding; every line above is a single publication or a single trial's own eligibility text, marked [single-source] throughout Section 3.
Thin: All seven findings are single-source, as marked in Section 3: the triage-algorithm predictors and odds ratio [1]; the pediatric-dentist multidisciplinary role [5]; the rural driving-distance and adjusted hazard-ratio figures [2]; the CHOP trial's own site-of-service eligibility text [3]; the AAP technical report's inpatient-observation and CPAP-adherence statements and its residual-OSAS range [4]; the telemedicine-adoption review [6]; and the domiciliary-testing implementation recommendations [7]. None of these is corroborated by a second independently-sourced publication in this pass.
Rescoped from class 3: None in this report. No question about what a clinician, parent, or family would do was posed here; [7]'s "parental preference" finding is the study's own reported result about a completed comparison, not this report's synthesis of a hypothetical.
Out of scope: CPT descriptors for PSG- and office-visit-level codes (AMA-licensed, per this report's scope note) were not retrieved even though they would sharpen the site-of-service and staffing-time picture further. No fda.gov guidance document was attempted (intermittent bot mitigation, per scope note). AASM's own accreditation technologist-staffing standard (a 2:1 patient-to-technologist ratio for attended PSG, confirmed by WebFetch of an aasm.org accreditation resource page, https://aasm.org/accreditation/resources/technical-staff-information, accessed 2026-09-01) is not carried into Section 3 or Section 4: the page has no resolvable identifier (no DOI, PMID, or comparable registry number) and does not itself distinguish pediatric from adult staffing, so it does not meet this report's sourcing bar — named here rather than silently dropped.
Not searched vs. not found: Not found, despite three distinct query attempts this pass ("pediatric polysomnography sleep laboratory staffing capacity United States," "adenotonsillectomy ambulatory surgery center site of service children obstructive sleep apnea," "pediatric otolaryngology wait time adenotonsillectomy access United States insurance"): a peer-reviewed, US-specific figure for PSG technologist staffing ratios, or for whether pediatric adenotonsillectomy defaults to same-day ambulatory discharge versus overnight admission at a population level (only the AAP technical report's qualitative "reinforces the need for inpatient observation" statement for a subgroup was located [4]). Not searched: state-level or payer-level variation in where pediatric PSG capacity sits (freestanding lab versus hospital-based lab), and any capacity or throughput figure for pediatric sleep-lab beds nationally.
[inference] None in this report's Section 3; every statement there is a source's own reported finding or eligibility text, not this writer's synthesis across sources.
