Cystic Fibrosis Presenting with New Respiratory Symptoms

Clinical Scenario

This protocol addresses the management of cystic fibrosis — including cystic fibrosis screen-positive, inconclusive diagnosis (CFSPID) and CF-related metabolic syndrome (CRMS) — when the patient develops new respiratory symptoms. Identifying and responding to these emerging symptoms early is a key clinical priority in this population.

Specific Situation

The clinical focus is on individuals with CRMS or CFSPID who present with new respiratory symptoms. This scenario calls for a selective, evidence-informed response to support airway health without over-treating.

Approach (Partial — See Full Protocol)

The recommended approach involves selectively offering a form of airway clearance therapy, with preference given to cost-effective methods. The complete structured regimen — including the specific indications, method selection, and sequencing — is available in the full protocol.

Full eligibility criteria, method details, and clinical decision points are in the protocol below.

The CFF recommends for people with CRMS/CFSPID experiencing new respiratory symptoms selectively offering the use of ACT (Grade C).

The use of cost-effective methods (such as manual percussion) should be attempted.
