Does a quit-smoking trial reflect routine care? Follow the resources

01

A familiar waiting room, an unfamiliar staffing budget

This exercise is entirely invented and reports no effect. A fictional trial recruits adults who already attend ordinary stop-smoking clinics, including people with different work schedules. Participants are randomly offered either the existing consultations or those consultations plus monthly group meetings. The usual clinicians deliver the meetings, and smoking status is assessed at six months using the outcome defined in the fictional protocol.

That sounds close to routine care. But the research budget also provides a coordinator to schedule meetings, extra clinician training and help with travel costs. Separate reminders are sent when research assessments are missed. The report does not yet say which of these arrangements would continue outside the trial.

An imagined clinic considering the report has no funded coordinator. Its available training and travel-support budget are unknown. The task is to identify what would need confirming, not to invent how much the quit rate would fall without those resources.

02

Ask what is being transferred

PRECIS-2 examines features of a trial relative to its intended usual-care setting. One feature can resemble routine practice while another is more tightly supported. Its original paper distinguishes resources essential to the intervention from extra research arrangements: if the coordinator or training is part of the proposed programme, it belongs in the description of the programme to be delivered, not in a list of disposable research luxuries.

Thus, ‘the clinic lacks a coordinator’ could mean it cannot deliver the tested package as described. It does not establish that the programme is ineffective. Conversely, calling everything research support would hide resources needed to reproduce the offer. Where the report leaves this distinction unclear, ask the authors who did which tasks and which costs belong to delivery.

Now compare the plan with the delivery record

CONSORT 2025 asks authors to describe both the planned interventions and how they were actually administered. A training session on the protocol is not proof that every meeting was delivered as intended. Read the actual staffing, meeting provision and receipt as well as the design.

End the exercise without awarding a realism score

The defensible summary of our fictional case is: ‘Randomised in ordinary clinics, with research-funded organisational support; whether the proposed clinic can supply the same delivery resources remains unresolved.’ This says what is familiar and what is missing without asserting a benefit or turning the study into a yes/no test of real-world effectiveness.

05

For a real paper, keep recruitment and measurement visible

Broad eligibility does not prove that everyone eligible enrolled. Reminders for an outcome assessment are not automatically counselling. Nor should they automatically disqualify a trial from being pragmatic: ask whether they change care or mainly help collect the outcome. Missing outcome data still need an explanation.

For an actual result, you would also need the comparator, defined smoking outcome, time point, estimate, uncertainty and risk of bias. A familiar setting answers none of those questions by itself. Use public study documents and service descriptions for this comparison; no personal smoking or health details need to be entered here.

06

An available service is a separate conversation

The NHS describes access to advisers through local stop-smoking services, GPs and pharmacists, with different routes across the UK. That helps identify where to ask about local support, not whether the invented trial package will work for you. Outside the UK, use an appropriately qualified local professional or service for personal support and treatment questions.

What to keep in mind

• Routine care is a named setting, not a universal condition.
• A hybrid trial can be useful without fitting a binary label.
• Do not remove delivery resources and assume you still have the tested package.
