Variation in training for interventional pulmonary procedures among US pulmonary/critical care fellowships: a survey of fellowship directors.

STUDY OBJECTIVES: The American College of Chest Physicians has published guidelines recommending minimum competency requirements for 17 interventional pulmonary procedures. Our aim was to assess what procedures are offered to fellows in US pulmonary/critical care fellowships and to determine whether the recommended competency numbers are being met. METHODS: Surveys were mailed to 122 pulmonary/critical care fellowship directors in the United States, and fellowship demographics, the types of procedures offered, and the average number of procedures performed were recorded. The presence of a dedicated interventional pulmonologist (IP) was ascertained, and procedural offerings and volume were compared with programs that did not have an IP. RESULTS: The response rate of the survey was 77%. There was wide variation in the procedures offered by different programs. The presence of an IP was associated with an increased likelihood of advanced procedural training in brachytherapy (p < 0.05), electrocautery/argon plasma coagulation (p < 0.001), stents (p < 0.001), laser therapy (p < 0.01), rigid bronchoscopy (p < 0.001), and cryotherapy (p < 0.05). For only 3 of the 17 procedures did > 50% of the programs reach the targeted numbers to obtain competency. CONCLUSIONS: There is a large variation in the spectrum of pulmonary procedures offered to trainees. Programs with a dedicated IP are more likely to offer training in advanced therapeutic procedures. When interventional procedures are offered by fellowships, < 30% of programs meet the competency recommendations. These findings have implications for training, delivery of care, and research. An extra year of fellowship in interventional pulmonology might be desirable if one is to reach the desired competency numbers. An alternative to reaching the recommended numbers for select procedures would be to consider regionalizing care at centers that perform many procedures. Finally, to provide justification for the current competency recommendations, clinical outcomes should be correlated with physicians' procedural volume, as has been done in other subspecialties.

Pleural manometry: technique and clinical implications.

INTRODUCTION: Pleural manometry during large-volume thoracentesis can prevent the development of excessively negative pleural pressures, which have been associated with re-expansion pulmonary edema; can diagnose an unexpandable lung; and can predict pleurodesis success. We currently perform pleural manometry simultaneously with both a vertical-column water manometer with an interposed resistive element, and a hemodynamic transducer connected to a standard physiologic system. We present the technique as well as the advantages and disadvantages of both systems in measuring pleural liquid pressures. TECHNIQUE: A flexible thoracentesis catheter is inserted in the most dependent portion of the pleural effusion. The water manometer consists of two lengths of IV tubing connected through a 22-gauge needle inserted into an injection terminal. The system is connected to the zeroing port of the pressure transducer, and both are carefully purged of air. The electronic system is zeroed at the level the thoracentesis catheter is introduced into the patient. Measurements are performed initially and after each 250 mL of fluid that is withdrawn. ACCURACY OF THE WATER MANOMETER: Forty consecutive patients who underwent therapeutic thoracentesis had pressure measurements. Pleural fluid removed ranged from 50 to 4,200 mL (mean, 1,445 mL). A total of 291 pressure measurements were acquired and analyzed. Mean pleural liquid pressure obtained by the water manometer had a strong positive correlation with the values obtained by a standard physiologic system (r = 0.97, p < 0.001). CONCLUSION: An overdamped water manometer is a valid method to measure mean pleural liquid pressure. Coughing invalidates pressure measurements with the water manometer; however, with the electronic method, periods of quiet breathing can be identified, allowing for the measurement of pleural pressure.
