Clinical Trial Summary
The overarching aim of this study is to investigate whether a new educational point-of-care
ultrasound course tailored for general practitioners working in office-based general practice
can lead to scanning competence at the end of the training program (three months after
baseline) and if scanning competence can be maintained six months after baseline.
Description:
Type of study:
This is a hybrid effectiveness-implementation study . The investigators will test the
effectiveness of a new type of point-of-care ultrasound course, tailored to meet the
educational needs of office-based general practitioners, in a real-world setting while
gathering information on its delivery and the implementation of the intervention.
Setting:
This study will be conducted in office-based general practice in Denmark with the educational
sessions taking place at an ultrasound educational facility.
The intervention:
The ultrasound course consists of three teaching seminars over three months, a curriculum of
10 point-of-care ultrasound (POCUS) applications, an online learning platform providing
educational support before, during and after the teaching sessions.
The online platform includes instruction videos demonstrating the performance of POCUS,
suggestions for additional literature, flashcards training the recognition of pathology,
participant assignments to support the development of skills, self-quizzes to focus attention
of learning outcomes and specific actioncards for each of the 10 POCUS applications framing
the examinations in the clinical context. In addition, the online platform gives participants
access to webinars and communication with other participants and teachers. A detailed
description of the educational elements in the ultrasound course can be found in the attached
study protocol.
Data collection:
The primary outcomes are the Objective Structured Assessment of Ultrasound Skills (OSAUS)
score scored three (outcome 1) and six months (outcome 2) after baseline.
The OSAUS assessment tool has been developed and validated as a generic tool for assessing
scanning competence. The OSAUS scale consists of seven items: 'indication for the
examination', 'applied knowledge of ultrasound equipment', 'image optimization', 'systematic
examination', 'interpretation of images', 'documentation of the examination' and 'medical
decision-making' and each item is rated using a provided five-point Likert-scale with
descriptions of performance ranging from very poor (score = 1) to excellent (score = 5). All
items are weighted equally, as high inter-item correlation have been found previously. Hence,
for each scanning modality a total score from 7 to 35 points may be achieved.
On the third teaching seminar (three months after baseline) and again six months after
baseline, participants will have their scanning competence assessed by external experts.
These experts are blinded to the participants previous experience and learning process.
The experts will assess the participants by asking the following questions:
- In which clinical scenarios would you perform this POCUS examination (Item 1 in the OSAUS)
The experts will ask participants to demonstrate the POCUS examination (for maximum five
minutes) to assess the following:
- Applied knowledge of the ultrasound equipment (Item 2 in the OSAUS)
- Image optimazation (Item 3 in the OSAUS)
- Systematic examination (Item 4 in the OSAUS)
- Interpretation of images (Item 5 in the OSAUS)
The experts will present the participants with two picture of common pathology and ask the
participants the following questions:
- How would you interpret these ultrasound findings? (Item 5 in the OSAUS)
- If you were to describe this examination in the medical record, what would you write?
(Item 6 in the OSAUS)
- What would you do if you found it? (Item 7 in the OSAUS) The OSAUS score will also be
used for secondary outcomes S1, S2 and S3)
Immediately before each competence assessment by experts, participants will be asked to fill
out a questionnaire where they declare whether or not they have POCUS scanning competence
within this scanning modality to perform the scan un-supervised in general practice (outcomes
6 and 7). The expert assessor are blinded to this declaration.
In addition, the following process-related outcomes will be collected:
The GPs keep a log book of all scans they perform. The number of scans of the 10 POCUS
modalities performed during months 1 to 3 and month 4 to 6 are summarized (outcome 8).
The GPs will register the number of adverse events and near-miss cases associated with their
use of POCUS during months 1 to 6, in a questionnaire specifically designed for this purpose
(outcome 9).
The GPs activity on the online platform will be registered during the educational period
(months 1-3) (outcome 10).
Background characteristics of participating GPs At baseline the following participant
characteristics will be collected: Age (years), gender (M, F, other), previous use of
ultrasound (number of months with regular use), previous ultrasound courses of minimum 1 day
duration (yes/no), scanner type (low range, mid range, high end), type of practice
(collaboration, partnership, solo), location of practice (urban, rural, mixed), number of
patients assigned to the practice, number of GPs working in the practice will be presented.
Data analysis:
All statistical analyses will be performed using STATA version 17 (StataCorp, Texas, USA) and
analyzed according to a predefined statistical analysis plan, which will be uploaded prior to
the data collection for the primary outcome (three months after baseline).
