简要总结
Title: The efficacy of medical students to correctly recognise pathological from non-pathological lung sounds over a period of time.
Methodology: Randomised, controlled trial, blind study.
Study Duration: The estimated duration for the main protocol (e.g., from the start of screening to the last subject processed and finishing the study) is approximately 6 months.
Study Centre: Lithuanian University of Health Sciences (LSMU).
Objectives: Primary Objective: To evaluate the accuracy of second-year & third-year students in correctly identifying pathological and not pathological lung sounds. Secondary Objectives: To evaluate the loss of the ability of the student to correctly identify pathological lung sounds over a period of time.
Number of Subjects: 140 randomised students in two groups; the first group is the control group (CNT), and a second group (EXP) will be exposed to pathological and none pathological lung sounds.
Diagnosis and Main Inclusion Criteria: Inclusion Criteria · Male and female second and third-year LSMU students, 18-40 years old, in any distribution. · Consent and compliance with all aspects of the study protocol, and methods, providing data during follow-up contact · See the methods section for the full list of inclusion criteria. Exclusion Criteria · Deafness · Age over 40 · Conditions that prevent the student from using earphones · See the methods section for a full list of exclusion criteria.
Regimen: CNT group will not receive training. Whilst group will receive 3-day training for 21 patient cases (57% with pathological lung sounds).
Statistical Methodology: Results will be analysed with the SPSS (version 27). A p-value < 0.05 will be considered statistically significant. The groups (CNT vs EXP) will be compared with the independent Student's t-test to see if there is a significant difference between the mean of the two groups. Though, if the data does not adhere to the parametric test's criteria a Mann-Whitney test will be applied. Whilst for the measurement made over 6 months of students' sensitivity, specificity, and accuracy (at intervals of 4, 10, 34, 184 -days) a one-way analysis of variance (ANOVA) statistical test will be applied for normally distributed data. Whilst, if data is not normally distributed a none parametric test will be applied such as Kruskal - Wallis method. McNemar's test will be applied to compare the performances of the same EXP students between their second- and third-year peers.
详细描述
Purpose: The primary objective is to evaluate the accuracy, sensitivity and specificity of 2nd and 3rd-year medical students' accuracy in identifying pathological sounds after 3 days of training.
Secondary Objective: To evaluate the loss of the ability of the student to correctly identify pathological lung sounds over a period of time when she/he does not undergo regular training.
Background: Auscultation is one of the four pillars of patient examination [1, 2, 3], and is particularly during a pulmonary objective investigation. Today, the assessment of auscultation sounds remains largely subjective and depends on the qualifications and expertise of a specialist [4, 5]. Arts et al. [6] recommend leaving the practice of traditional auscultation to experienced specialists since sensitivity is as low as 37% when identifying between normal cases and several lung pathologies. Furthermore, auscultation skills require continuous practice and can even degrade over time [7], but can be improved through training [2]. Hence in our research were are interested to investigate the effect of training on medical students' accuracy to identify lung sounds correct. The research is created to investigate skill deterioration over a period of time. Investigator's expectations are that the research will provide us with a better understanding of how often healthcare staff should undergo training to maintain a good standard.
Goals of the study:
To evaluate the specificity, sensitivity and accuracy of 2nd and 3rd-year medical students whilst identifying lung sounds.
