Survey of Infection Prevention and Control Practices Among Hematopoietic Stem Cell Transplant Centers
Bibliographic record
Abstract
Background. There is a desire to standardize Infection Prevention and Control (IPAC) strategies among hematopoietic stem cell transplant (HSCT) centers. Methods. A survey was performed of members of the American Society of Transplantation Infection Diseases Community of Practice on November 2014 and February 2015 on institutional IPAC policies on HSCT patients. Results. There were 38 providers from 28 centers from the United States, Canada, Switzerland, India, South Korea, and Taiwan who responded to the survey. Most use HEPA-filtered rooms for allogeneic HSCT patients (all times [44%], within 3 months of HSCT [28%], or when clinically indicated [8%]). In contrast, 28% do not provide HEPA-filtered rooms after autologous HSCT. Positive pressure rooms are used after allogeneic HSCT in majority of centers (all times [25%], immediate post-transplant [37.5%], when clinically indicated [16.7%]); usage after autologous HSCT are 24%, 16%, and 20%, respectively. A quarter (26.1%) requires health care providers to perform additional hand hygiene beyond standard handwashing, such as use of gloves during all patient contact (12% and 15.4%, respectively). Only a small number of centers have dedicated medical equipment for use at all times (8.3% allogeneic, 7.7% autologous) or perform measures beyond standard room cleaning (13% allogeneic, 8.3% autologous), mostly with terminal bleach cleaning. A fifth does not require patient room doors to be closed (20.8% allogeneic, 20% autologous). No center requires routine use of isolation gowns, and all recommend using them only when clinically indicated. No center allows for plants or flowers in HSCT units. The majority allows use of personal belongings (62.5 % allogeneic, 73.1% autologous). All centers require patients to wear masks when leaving the hospital room or hospital, most commonly during the first 3 or 6 months after HSCT. Majority does not allow animals in hospital rooms (81.8% allogeneic, 80% autologous), and for those that do, these are limited to personal pets (dogs, cats) and service animals. Visitor age restriction varied from <5 years to <15 years in a third of the allogeneic and autologous HSCT centers (32% and 29.6%). Conclusion. This survey highlights varying degrees of implementation of IPAC strategies after HSCT. National guidelines exist to guide many IPAC strategies, but their clinical implementation is variable.

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.
