Use of a Novel, Shortened, Indwelling Pleural Catheter (PleurX) for the Ambulatory Management of Malignant Pleural Effusion
Bibliographic record
Abstract
BACKGROUND: Indwelling pleural catheters are frequently used for the treatment of malignant pleural effusion. The PleurX catheter (Becton, Dickinson and Company) is a commonly used indwelling pleural catheter across Canada. The traditional PleurX catheter is designed with a long segment of tubing outside of the patient's chest, making insertion, drainage, and dressing changes awkward. Our clinic developed a novel, shortened, PleurX catheter that is easier to handle. METHODS: We conducted retrospective chart review for all patients treated with a shortened PleurX catheter at our center from December 2015 to May 2019 and demographics, clinical information, and complications were recorded retrospectively. A survey was designed and distributed to nurses experienced with the use of both catheters to elicit a preference between the short and long catheter. RESULTS: We analyzed data from 503 catheters placed in 491 patients. The most frequently encountered complications were loculation requiring fibrinolytic (2.4%), catheter dislodgement (1.2%), and pleural infection (0.6%). Of nurses surveyed, 74% preferred using the shortened PleurX catheter. CONCLUSION: Complication rates of the novel, shortened PleurX catheter are low. Further research is needed to better determine the optimal catheter length for ambulatory management of malignant pleural effusion.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
