Curriculum Development and Evaluation of a Hemodynamic Critical Care Ultrasound: A Systematic Review of the Literature
Bibliographic record
Abstract
OBJECTIVE: The application of ultrasound to assess a patient's cardiac function and volume status is becoming commonplace in the practice of critical care. These skills have been taught through varying curricula; however, no consensus on the optimal curriculum has been established. The purpose of this systematic review is to evaluate the literature regarding critical care ultrasound curriculum development and evaluation. DATA SOURCES: Studies were identified using MEDLINE, Embase, CINAHL, PsycInfo, the Cochrane Center Register of Controlled Trials, and ERIC according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines through June 2014. STUDY SELECTION: Included studies were limited to those that described adult (age, > 16 yr) cardiac or hemodynamic critical care ultrasound curricula for physicians. Two reviewers independently screened studies based on predetermined exclusion criteria, and disagreements were resolved by a third reviewer. DATA EXTRACTION: Data were abstracted, and quality was assessed by two reviewers using the Newcastle-Ottawa Scale. Data abstracted from the studies included the learner population, examination type, duration, composition, and setting of the curriculum, means of evaluation, and outcomes. DATA SYNTHESIS: The search yielded 654 studies; of which, 15 met inclusion criteria. All curricula used a combination of didactic and hands-on components. The highest agreement between novice and experts, coupled with the most time-efficient application, was achieved when the study was limited to a basic qualitative approach for the assessment of global function or contractility and assessment of inferior vena cava collapsibility. The mode of delivery seemed most efficient when a hybrid method was used, including online instruction. Minimum scanning competency may be achieved with 30 scans although more rigorous study on this element is necessary. CONCLUSIONS: Assessment of cardiac function and volume assessment is becoming an essential skill in critical care medicine. Physicians can be taught bedside echocardiography in a time-effective manner with positive benefit to patients by applying a concise curriculum with limited content.

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.
