Introduction

The course will provide the student with the knowledge for the correct indication and use of diagnostic tests (DT) in clinical practice.

The DT have contributed to great advances in medicine by making available to the physician sensitive and specific information of great help in the diagnosis. The imaging tests provide a very precise degree of anatomical detail, fundamental for clinical and therapeutic decisions.

The indication of the DT should be made based on the clinical reasoning generated by the careful study of the patient, observation and physical examination. The doctor must know how to use the DT with criteria and moderation and assess whether the results will modify the treatment or benefit the patient.

You have to know the information provided by each of the DT, as well as their limitations and possible harm to the patient.

Pre-course requirements

The student must have knowledge of the pathological processes of the different organs and systems, as well as know the repercussion on the organism.

The student must know the basic physical and biochemical foundations of the different types of DT.

 

It is essential that the student has completed and approved the subjects:

Semiology and Physiopathogeny

Biochemistry

Objectives

To learn the indication and assessment of DT in clinical practice.

 

Specific objectives:

 

1. To know the theoretical foundations of the tests / complementary explorations.

 

2. To know the indications of the DT. Place the DT as a support tool in the diagnostic and therapeutic aspects of the clinical history and patient care.

 

- To know the indications of the different DT.

 

- To know the information that can contribute and the limitations of the exploration.

 

- To evaluate the efficiency of each exploration.

 

- To recognize the importance of searching for the best evidence.

 

- To know sensitivity and specificity of each exploration.

 

- To know how to interpret the results of the tests and the correlation with the clinic.

 

3. To know how to inform the patient.

 

- To offer information to patients about the explorations to be performed.

 

- To obtain written informed consent.

 

4. To know the conditions of the tests.

 

- To assess the suitability of the treatment according to the patient's situation.

 

- To assess the limitation of the diagnostic - therapeutic effort.

 

- To know the limitations and contraindications of the DT.

 

- To know adverse and secondary effects of DT.

Learning outcomes of the subject

The student plans the study of DT (indication, priority and staging by complexity) based on clinical reasoning and differential diagnosis.

 

The student knows the DT, informs the patient of the risk - benefit that they entail, and asks for informed consent.

 

The student values the information provided by the test and makes a critical contrast with the clinic.

Teaching and learning activities

In person



The master class is the scenario in which a teacher transmits knowledge in a classroom to the whole group of students. The format, however, allows the introduction of activities in small groups within the classroom and the development of strategies that encourage the active participation of students.

Script:

Approach to the major clinical syndromes of the system (reason for study)

• List of complementary tests that are used for the study of the organ / system

- Structural study tests - Structure of the apparatus - system

- Functional study tests - Function of the device - system

- Structural and functional study tests

- Other diagnostic tests.

 

• List of the main syndromes that are presented for study and that will be presented in the class, is part of the script of the class.

• Study process based on the differential diagnosis of a specific clinical / syndromic situation.

• What tests do we use and in what order / priority ?. Argumentation, to what the priority obeys.

• Expected results of the tests. Contrast results of complementary tests with the patient's clinic: interpretation of results in the clinical context, false positives, false negatives, ...

The case method consists of the process of solving clinical cases or those specific to the profession. They are activities in groups that are resolved with the active participation of the teacher after the students' deliberation.

 

The teacher defines the learning objectives he wants the students to achieve.

Clinical cases. Process of analysis of the clinical information of the case. Development of the differential diagnosis. Development of the study process of a specific clinical - syndromic situation through diagnostic tests

Problem-based learning has similarities to the case method but differs in that students are held responsible for finding the solution to the problem. The teacher acts as a tutor that facilitates the learning process based on their metacognitive abilities. It is developed in small groups.

The skills laboratory is an area in which the student can basically develop communication and physical examination skills based on mannequins and clinical cases. They are developed with small groups.
