Filter by:Title: The Effect of White Noise on the Ability of a Medical Student to Recognise Correctly Adventitious Lung Sound. Methodology: Randomized, 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 4 weeks. Study Centre: Lithuanian University of Health Sciences (LSMU) and Kaunas Hospital of LSMU. Objectives: Primary Objective: To evaluate the accuracy of second-year and third-year medical students in correctly identifying pathological and nonpathological lung sounds under different white noise levels. Number of Subjects: A group of 104 students will be exposed (EXP) to learning pathological and nonpathological sounds for 3 days. After 3 days students will take 3 tests with different levels of white noise pollution added ( signal-to-noise ratio (SNR) 20, 40 and none added). 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. Please, see the methods section for a full list of inclusion criteria. Exclusion Criteria: deafness; age over 40; conditions that prevent the student from using earphones. Please, see the methods section for a full list of exclusion criteria. Regimen: EXP group will receive 3-day training of 101 lung sounds. Statistical Methodology: Results will be analyzed with the SPSS (version 27) and Jamovi (version 2.3.21). A p-value < 0.05 will be considered statistically significant. The effect of 3 levels of white noise on the EXP group will be compared utilizing a one-way analysis of variance (ANOVA) statistical test. Though, if data does not adhere to a normal distribution then Kruskal - Wallis will be applied. McNemar's test will be used to compare if there was a statistical difference between second-year and third-year students.
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.
In the present trial, the StethoMe electronic stethoscope will be used for pulmonary auscultation and recording of lung sounds in the pediatric study population.
