Effectiveness of a primary care clinical ultrasound classroom for family physicians as a formative intervention system, a quasi-experimental trial Study protocol

Introduction: Clinical ultrasound is a technique that increases diagnostic capacity and facilitates clinical decision making. The objective is to develop and validate an ultrasound training methodology oriented to the clinical practice of the family physician. Methods: Quasi-experimental study, with a before/after design, a control group, and 1 year of follow-up. Twenty family physicians working in primary care health centers with a list of over 800 patients will be included, as well as a control group of family physicians with similar characteristics in terms of age, sex, and patient list. A structured training process oriented to the clinical practice of the family physician, primary care clinical ultrasound classroom (AECAP), will be carried out, and the improvement of knowledge and skills of the participants will be evaluated, as well as the improvement of the quality of care based on clinical indicators. Discussion: The family physician is in a privileged situation allows increasing the performance of ultrasound in frequent clinical situations and reducing care hours. We hope that the results obtained in this study demonstrate the effectiveness of the structured training method (AECAP) and support the generalization of ultrasound in primary health care. Ethics and dissemination: The study was approved by the Medical Research Ethics Committee of Salamanca on December 17, 2018 (cod 2018 11 134). The trial was registered in ClinicalTrials.gov provided by the US National Library of Medicine-number: NCT04283383.
