Tetrasodium EDTA central venous catheter lock solution in home parenteral nutrition patients: Ease of use and patient satisfaction, a prospective study
Bibliographic record
Abstract
Objective: Chronic intestinal failure is a devastating chronic medical condition, which requires central venous access for parenteral nutrition infusion. The presence of a central venous line is associated with an increased risk of bloodstream infection and thrombosis. Currently, the heparin lock is the most used catheter lock, but still has risks for line infection. The 4% tetrasodium EDTA catheter lock (KiteLock™) solution, has demonstrated a decrease in infection and thrombosis risk, but requires extra steps for the preparation and infusion. The objective of this study was to evaluate the patients ease-of-use and acceptability of the new KiteLock solution in the home parenteral nutrition (HPN) patients. Methods: This prospective, open-label, single-center study evaluated patient acceptability of tetrasodium EDTA (KiteLock) in HPN. Patients were contacted four times, beginning with an instructional visit by the HPN nurse. They then completed three 30-day phases: standard heparin/saline flush, tetrasodium with withdrawal (when feasible), and tetrasodium EDTA. During the final week of each phase, patients completed a phone survey and questionnaire with the HPN nurse. Results: Of the 21 patients enrolled, 14 completed the study. Seven did not: two withdrew due to time constraints, two found KiteLock difficult to infuse, and three had incomplete data. Among those who competed the study, some reported reduced ease-of-use with KiteLock (1 hard to open, 5 difficulties withdrawing, 1 overall difficulty), though most still rated it easy or very easy. Three patients continued to find it more difficult by study end. No adverse effects were reported. Preparation time decreased over time as patients adapted. Initial satisfaction with KiteLock was lower (50% find it neutral), but improved with familiarity, becoming comparable to heparin with 12 patients satisfied ( N = 14). Conclusions: KiteLock solution is well accepted by the patient or caregiver, despite involving more steps to use it.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
