NCT06245954

Brief Summary

The aim of this study was to conduct a prospective randomized controlled trial to design simulator and in vitro lung standardized training, to perform a learning curve evaluation of transbronchial lung cryobiopsy (TBLC) operating physicians, and to assess the role of standardized training in TBLC.

Outcome Measures

Primary Outcomes (3)

  • Obtain pathologic quality assessment of specimens

    The quality of TBLC sampling specimens was scored by two professional pathologists on a specialized pathology scale.

    1 month

  • histopathological pattern diagnosis rate

    Diagnosis of histopathological patterns was performed by two specialized pathologists to determine a consistent diagnostic rate.

    1 month

  • diagnostic rate of multidisciplinary discussions

    Diagnostic rates based on composite TBLC, BAL, clinical and imaging data in a multidisciplinary discussion by clinical experts

    1 month

Secondary Outcomes (1)

  • Occurrence of short-term adverse events

    24 hours or 7 days

Study Arms (2)

Standardized training group

EXPERIMENTAL

The bronchoscopists in this group will accept simulation training by means of simulators and extracorporeal lungs

Other: simulated training

Traditional teaching model group

OTHER

The bronchoscopists in this group will accept traditional lectures, hands-on demonstrations and so on to learn TBLC

Other: traditional bedside teaching

Interventions

Simulation training of bronchoscopists by means of simulators and extracorporeal lungs

Standardized training group

TBLC training for bronchoscopists through traditional lectures, hands-on demonstrations
