An assessment and model exist. Does new evidence justify an update?

New trials, prices or utilization patterns appear, and the team needs regular checks of their impact on the original assessment.

How does this scope address your concerns?

You do not want to fund a fresh start each time or receive article replacements without an explanation of model impact.

When this scope fits

An existing baseline HTA and model authorized for reuse, with 2 fixed services to maintain.

When the scope needs adjusting

No baseline model but an expectation that annual maintenance includes building one, or unlimited products and complete HTAs.

Scope & acceptance

Work covered by the quote

Illustrative scope: 2 services, quarterly scans and 4 change briefs, up to 120 new full texts/year, 2 in-scope model updates and 4 discussions.

Pilot reference: CNY 300,000–1,000,000 or more/year. Fictional CNY 300,000 annual fee: 180,000 for evidence and parameter monitoring and 120,000 for 2 model updates and review support; 75,000/quarter. Building a missing baseline model is excluded.

Acceptance criteria

Each scan records coverage and changes to conclusions. Monitoring is not automatically presented as a complete new HTA.

Checking the evidence

Volumes come from the current proposed pilot scope. The budget and scenario are illustrative, not a completed client project or real transaction. A formal quote follows confirmation of scope, data permissions and personnel.
Inputs to confirm: baseline HTA title and date, model version, parameter dictionary, authorized new data and predefined update triggers.

Define the task

Confirm whether the baseline assessment, model files and parameter sources can be reused.

Methods, sources and professional responsibilities

THE BASIS FOR THIS SCOPE

Why this approach? Inspect the basis.

Institutional decisions require effect evidence, resources, implementation conditions and local applicability.

OFFICIAL GUIDANCE

WHO Guidelines

World Health Organization

Inspect public-health and clinical guidance

Find WHO guidelines and review the recommendation questions, evidence base and intended settings.

Scope & access conditions

Global guidance is not evidence of local implementation outcomes. Check population, resources, policy and timing.

PUBLIC DATABASE

Explore a question’s research synthesis and the confidence researchers have in the findings.

Scope & access conditions

Plain-language summaries are public; full-review access varies. Applicability still depends on the population and question.

METHOD REFERENCE

GRADE · Cochrane Handbook

Cochrane · Chapter 14

Show effect size and confidence separately

Present important outcomes, relative and absolute effects, available data and certainty, with reasons for downgrading.

Scope & access conditions

GRADE evaluates a body of evidence for a particular outcome. Database inclusion or one study does not automatically establish high certainty.

Open official source

These references support problem definition and evidence appraisal. Your conclusions still require project-specific sources and professional review.

The value of this commissionEOS preserves parameter and version differences for two baseline services, with explicit reassessment triggers.

Annual payer evidence maintenanceCompare alternatives and value

After assessment, which new findings could materially change a coverage decision?

What to assess	symplr / Hayes / EVERSANA	Evidence OS · Commissioned scope
Service focus	Hayes maintains an updated library; EVERSANA offers economic and value-evidence services.	EOS preserves parameter and version differences for two baseline services, with explicit reassessment triggers.
When to choose	Libraries suit broad coverage; complex cross-market reassessment needs full HTA expertise.	Example: two services, four scans/briefs, up to 120 full texts and two scoped model updates.

What the fee pays for: Planning reference: CNY 300,000–1,000,000+ annually; a missing baseline HTA is a separate project.
Value beyond this task: Retain the model, previous versions and reasons for change; renew around incremental work.
How to assess value: Count reused models/sources and avoided repeat-review hours; do not promise a payer saving percentage.

Check included model work, materiality reviewers and how absent triggers are documented.

Reuse and updates after delivery

A change history from the original assessment to the current version lets new committee members check why an update was—or was not—made.

Agree reuse rights, retention and export periods, and future update fees when scoping.

Questions before commissioning

Is each quarterly scan a complete new HTA?

No. Monitoring, model changes and comprehensive reassessment are recorded separately. A new complete HTA needs its own scope.

How are periods without a model-update trigger charged?

Tasks are not invented. Reserved-service terms and settlement for untriggered work are agreed in the contract first.
