Evaluation of proficiency in using different inhaler devices among intern doctors

Area of Science:

• Respiratory Medicine
• Medical Education

Background:

• Inhaler device misuse by patients contributes to poorly controlled asthma and COPD.
• Physician deficiencies in inhaler device use can lead to improper patient techniques.

Purpose of the Study:

• To assess the proficiency of intern doctors in using various inhaler devices.
• Evaluate intern doctors' skills in identification, preparation, administration, and explanation of inhaler devices.

Main Methods:

• Seventy interns were evaluated on their ability to use pressurized metered dose inhaler (pMDI), pMDI with spacer, rotahaler, turbuhaler, and nebulizer.
• A structured assessment scored device identification, preparation, administration, coordination, and explanation skills.
• Common errors, including failure to shake pMDI and inadequate breath holding, were recorded.

Main Results:

• Interns demonstrated high identification rates for pMDI, pMDI with spacer, rotahaler, and nebulizer, but low for turbuhaler.
• Preparation and correct administration skills were notably poor for turbuhaler and suboptimal for pMDI devices.
• Coordination and explanation skills varied, with significant deficits in turbuhaler usage and explanation.

Conclusions:

• Intern doctors exhibit poor proficiency across various inhaler devices.
• Inadequate training in inhaler device usage necessitates targeted educational interventions for medical graduates.
• Improved training is essential for future physicians to effectively manage asthma and COPD patients.
