Incense (bakhour) smoke exposure is associated with respiratory symptoms and impaired lung function among adults: A cross-sectional study in Eastern Province of Saudi Arabia.

Burning incense (bakhour) is a common cultural practice in Saudi Arabia. However, its health risk assessment has rarely been studied. This study aims to investigate the association between exposure to incense smoke on lung function impairments and respiratory symptoms among young adults in Saudi Arabia. A community-based cross-sectional study was designed with a representative study sample (N = 125) in the Eastern Province of Saudi Arabia. Study participants, exposed group (n = 45), working in bakhour shop and matched control (n = 80), no history of occupational exposure to bakhour smoke, were recruited randomly from the population registry. Socio-demographic and respiratory symptom information were collected through a questionnaire developed based on European Community Respiratory Health Survey II (ECRHS II). Lung function measurements were conducted using a field spirometer. The overall prevalence of wheezing or whistling was 16.8%, with a higher prevalence in exposed group 35.5%. In adjusted models, exposed to incense smoke remained positively associated with respiratory symptoms: wheezing or whistling; breathlessness; chest tightness shortness of breath; woken up by an attack of coughing. Our study suggests that inhaled incense smoke in occupation or at home is a risk factor of lung function impairments among adult population in Saudi Arabia.

Simulation-based Clinical Education Versus Early Clinical Exposure for Developing Clinical Skills in Respiratory Care Students.

Background: Early clinical exposure (ECE) has been shown to improve clinical skills, but several factors limit its implementation. Objective: To compare the use of simulation-based education (SCE) and ECE in improving respiratory care students' clinical skills in laboratory settings. Methodology: This experimental prospective study was conducted among respiratory care students at Imam Abdulrahman Bin Faisal University, Dammam, Saudi Arabia. Students from one batch were allocated to the ECE group, and students from another batch were allocated to the SCE group to concurrently undergo clinical training. On completion of the course, students completed the Clinical Learning Environment Inventory (CLEI), and their clinical practice course grades were evaluated. Results: A total of 72 students from the two batches completed the CLEI and clinical performance evaluation; 32 (45%) were female. The mean age was similar across both groups. Between the groups, there was no statistical difference in the mean clinical grade (95% CI) (ECE: 167.29 [164.74-169.84], SCE: 166.88 [164.12-169.65]; P = 0.837) and the CLEI score (ECE: 128.25 ± 3.9, SCE: 123.08 ± 4.2; P = 0.381). Multivariable linear regression analyses revealed no significant difference in the clinical performance grades (ß = -0.09; 95% CI: -0.78-0.59; P = 0.788). Conclusion: The study found no significant difference in the performance between ECE and SCE in laboratory settings, indicating that SCE is a viable alternative to ECE in RC clinical training. Studies with larger cohorts are required to corroborate this finding.
