Enable an agent to recognise tonsillitis, represent the evidence and course of individual episodes, and identify appropriate assessment, review and escalation pathways.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify.

Purpose and description
Enable an agent to recognise tonsillitis, represent the evidence and course of individual episodes, and identify appropriate assessment, review and escalation pathways.
Tonsillitis is inflammation of the palatine tonsils, usually caused by viral or bacterial infection, which may occur as an acute illness or recur in separate episodes.
It can be Assemble a tonsillitis episode account with dated symptoms, examination findings and diagnostic uncertainty.; Identify missing evidence needed to distinguish tonsillitis from neighbouring throat conditions.; Compare available evidence with an applicable, versioned assessment pathway and expose unmet prerequisites.; Flag documented severity or complication concerns for clinician review using a sourced escalation pathway.; Summarise documented recurrence and functional burden for specialist assessment.; Link terminology codes and management decisions to their source, version and applicable population..
Distinguishing features
Require evidence localising inflammation to the tonsils when distinguishing tonsillitis from an undifferentiated sore throat. [NHS tonsillitis overview](https://www.nhs.uk/conditions/tonsillitis/)
Separate the anatomical diagnosis from its cause: viral and bacterial infections can both produce tonsillitis. [NHS tonsillitis overview](https://www.nhs.uk/conditions/tonsillitis/)
Record inflammatory evidence separately from tonsil size, so enlargement alone is not treated as sufficient diagnostic evidence.
Separate a continuous episode from recurrent episodes using documented recovery intervals and an explicit episode definition.
Distinguish uncomplicated tonsillar illness from suspected peritonsillar abscess, which involves a collection of pus beside the tonsil. [NHS tonsillitis overview](https://www.nhs.uk/conditions/tonsillitis/)
Scope
+ Tonsillar inflammation and evidence supporting its clinical identification
+ Acute episodes, resolution, recurrence and explicitly defined persistent presentations
+ Suspected or established infectious causes and the evidence supporting attribution
+ Symptoms, examination findings, functional impairment and complication concerns
+ Versioned diagnostic terminology, assessment guidance and management decision criteria
+ Population-specific evidence and documented limitations of its applicability
- The patient's complete health record and identity
- Care encounters, prescriptions and surgical procedures as operational records
- Pharyngitis without established tonsillar involvement
- Isolated tonsillar enlargement, tonsil stones and sleep-disordered breathing without tonsillitis
- Complete models of causative pathogens or systemic infections
- Independent models of peritonsillar abscess, deep neck infection and other complications
Characteristics
- Anatomical involvement
- Tonsil site; left, right, bilateral or unspecified; associated pharyngeal involvement Establishes the anatomical boundary and preserves asymmetry for clinical review.
- Diagnostic assertion
- Suspected, clinician-diagnosed, disputed, excluded or unresolved; assessor and timestamp Separates an observation from an attributed diagnosis.
- Episode duration
- Days since reported onset; onset uncertainty and observation date Supports assessment of persistence and change without imposing an unsupported duration threshold.
- Tonsillar examination
- Erythema, swelling, exudate and asymmetry, each present, absent or not assessed; examination method Retains the evidence behind the diagnosis without turning an isolated sign into proof of cause.
- Swallowing and hydration
- Ability to swallow saliva and fluids; intake change; hydration assessment; unknown allowed Captures functional consequences relevant to urgency and care feasibility.
- Measured temperature
- Degrees Celsius with measurement method and time; reported fever stored separately Distinguishes measured evidence from symptom recall.
- Aetiological attribution
- Suspected or established cause linked to supporting observations, test results and interpretation Keeps infectious cause and confidence separate from the tonsillitis label.
- Recurrence burden
- Qualifying episodes per explicitly dated interval; disabling days and documentation completeness Makes recurrent-disease assessments auditable.
- Terminology mapping
- ICD-10, ICD-11 or SNOMED CT concept, release, edition or extension, jurisdiction and mapping scope Prevents codes for different presentations or terminology releases from being treated as interchangeable.

Drafted structure
Bundle to layer to finding to question, as the second pass will find it: 7 bundles · 13 layers · 20 findings · 32 questions.
Tonsillitis identity Define the clinical concept and keep its terminology distinct from related throat disorders.
A sore-throat label, a tonsillar finding and a tonsillitis diagnosis carry different commitments.
Anatomical boundary
Locate the inflammation and describe overlap with pharyngeal disease.
Tonsillar involvement
Require explicit evidence or an attributed clinical assessment of tonsillar involvement.
- What observations support tonsillar inflammation, and which tonsillar site was examined? definition
- Is this tonsillitis, pharyngitis with tonsillar involvement, or a sore throat whose site remains uncertain? boundary
Diagnosis and coding
Separate the condition from diagnostic assertions and terminology representations.
Versioned clinical label
Attach coding scope and provenance to each diagnostic label.
- Who asserted the diagnosis, when, and with what stated certainty? provenance
- Which verified ICD-10, ICD-11 or SNOMED CT concept applies, in which release and jurisdiction, and does it distinguish acute, recurrent or chronic presentations? definition
Cause and diagnostic evidence Represent the evidence for infectious cause and alternative explanations.
The tonsillitis diagnosis alone does not establish which organism, if any, has been demonstrated.
Clinical assessment
Organise observations and any applicable clinical prediction tools.
Assessment rule applicability
Keep a clinical score's intended use distinct from anatomical diagnosis and microbiological confirmation.
- If FeverPAIN, Centor or another rule is used, which issuing guideline, version, age range and intended decision apply? provenance
- Which required observations were measured, reported, absent or unassessed, and can the rule validly be applied? measurement
Pathogen attribution
Link suspected causes to tests and clinical interpretation.
Test result meaning
Preserve the distinction between detecting an organism and attributing the episode to it.
- What specimen, collection time, assay and result support the proposed cause, including timing relative to antimicrobial exposure? provenance
- How was the result interpreted for this presentation, including possible carriage, test limitations or a systemic infection with tonsillar manifestations? boundary
Episode course and severity Describe the current illness over time and its effect on function.
Urgency and recovery cannot be judged from the diagnostic label alone.
Episode timeline
Track onset, progression and recovery without assuming universal stages.
Dated illness trajectory
Maintain a time-linked account of symptoms and examination changes.
- When did symptoms begin, and which dated observations establish improvement, stability or worsening? measurement
- What evidence establishes resolution, persistence or a distinct new episode rather than another visit for the same illness? boundary
Functional impact
Record swallowing, fluid intake, pain and disruption to ordinary activity.
Swallowing and illness burden
Capture impairment with a method appropriate to the person's age and communication abilities.
- Can the person swallow saliva and fluids, and what evidence describes intake and hydration? measurement
- How were pain, sleep disturbance and missed school, work or usual activities assessed and dated? measurement
Complications and escalation Identify observations requiring reassessment of uncomplicated tonsillitis.
A model must expose evidence of a potentially different or more urgent condition.
Urgent assessment
Connect severity observations to applicable clinical escalation guidance.
Airway and swallowing concerns
Record breathing, swallowing, speech and mouth-opening concerns that feature in urgent tonsillitis advice. [NHS tonsillitis overview](https://www.nhs.uk/conditions/tonsillitis/)
- Are breathing difficulty, inability to swallow, altered speech, mouth-opening difficulty or rapidly worsening swelling present, absent or unassessed? measurement
- Which current local pathway determines the required urgency and destination of clinical assessment? action
Complication boundary
Link suspected complications without absorbing their full models.
Abscess or alternative pathology
Preserve suspicion, investigation and specialist conclusions as distinct states.
- What findings prompted concern for peritonsillar abscess, deeper infection or another explanation for persistent or asymmetric tonsillar findings? boundary
- Which assessment established or excluded the suspected condition, and where is its separate clinical record linked? provenance
Management and response Represent the reasoning, applicability and review of episode management.
An agent needs to distinguish a supported management option from an automatic consequence of a label.
Management eligibility
Connect proposed care to evidence, patient context and guideline scope.
Treatment decision basis
Record the basis for supportive care, testing or antimicrobial consideration without embedding unsourced prescribing rules.
- Which guideline and episode evidence support the proposed management, and what uncertainty remains about infectious cause? action
- Which linked patient factors, such as age, allergy history, immune status or ability to take oral treatment, affect applicability? boundary
Response and review
Track outcomes and explicit reassessment conditions.
Management follow-through
Separate proposed, delivered and completed interventions from observed response.
- What care was actually received, and how did symptoms, intake and function change afterward? measurement
- What review interval and deterioration criteria were documented, and who is responsible for reassessment? action
Recurrence and population context Represent longer-term tonsillitis burden and the population limits of supporting evidence.
Repeated throat symptoms require qualification before they support recurrence claims or specialist decisions.
Recurrent illness
Count qualifying episodes and support review of persistent or recurrent disease.
Qualified recurrence burden
Keep episode evidence, functional burden and referral criteria separately inspectable.
- How many distinct episodes meet the cited tonsillitis definition within each dated interval, and which are documented versus recalled? measurement
- Which versioned specialist-referral or tonsillectomy criteria apply, including burden, exceptions and patient preferences? action
Population evidence
Qualify epidemiological estimates and clinical evidence by population and setting.
Evidence denominator and transfer
Prevent estimates for sore throat, attendance or bacterial infection from silently becoming estimates for tonsillitis.
- For any incidence or prevalence estimate, what case definition, age group, geography, year, denominator and ascertainment method were used? provenance
- Does the evidence concern tonsillitis specifically, and which differences limit its application to the population being modelled? boundary
Evidence and external alignment What the world already says about this thing, gathered so the model can be checked against it.
A model that cannot be lined up against existing standards, identifiers and practice cannot be adopted by anyone who already uses them.
