About this study
Official title: Evaluation of Inhalation Technique in Patients With Chronic Obstructive Pulmonary Disease (COPD), Asthma or Asthma-COPD Overlap Syndrome(ACOS) Using a Dry Powder Device at Chest Clinic in Dhulikhel Hospital
This study analyzes the prevalence of patients using inhalation devices via incorrect technique and access the adherence of patients to correct inhalation technique when taught along with their subjective improvement of symptoms.
Read the detailed description
This is a one group pretest- posttest design conducted in all patients presenting in Chest clinic of Dhulikhel Hospital-Kathmandu University Hospital, Nepal from March 2017 to May 2017. Patients diagnosed of having COPD, Asthma or Asthma-COPD Overlap Syndrome (ACOS) and were under inhalation bronchodilators in the form of Dry Powder Device via Rotahaler were included. Enrolled patients are assessed for inhalation technique compliance at their routine medical (pre-training) visits by physician. The use of inhaler device is evaluated in a practical manner by asking the patients to demonstrate their inhalation technique. After the assessment, instructions and training are given until they can use the device correctly. One month later (post-training), all patients are re-evaluated in regards to inhalation technique and subjective improvement of symptoms.

What is being measured
The primary outcome is the main question the study is designed to answer.
Change in 'Inhalation Scores" After a month from Baseline
An observation checklist measuring essential steps required for adequate drug delivery for Rotahaler was developed. The number of required steps are seven and the correctness of the seven-step inhalation technique was measured by giving a score 0 for incorrect action and 1 for correct action. Each of the seven steps were scored 1 or 0, giving a total score of 0-7. After assessment, instructions were given with demonstrations regarding the correct use of Rotahaler. One month later (post-training visit), all patients were re-evaluated
Measured: After a month
Secondary outcomes (3)
Prevalance COPD, Asthma and Asthma COPD Overlap Syndrome inpatients visiting Chest Clinic of Dhulikhel Hospital- Kathmandu University Hospital.
Calculating the prevalence of the three medical conditions in Chest clinic of Dhulikhel Hospital
Measured: 3 months
Associated Factors for Incorrect Inhalation Technique
The potential associated factors for an incorrect inhalation technique to be calculated via univariable logistic regression analysis
Measured: 3 months
Prevalence of patients using the inhalation devices via incorrect technique
An observation checklist measuring essential steps required for adequate drug delivery for Rotahaler was developed. The number of required steps are seven and the correctness of the seven-step inhalation technique was measured by giving a score 0 for incorrect action and 1 for correct action. Each of the seven steps were scored 1 or 0, giving a total score of 0-7.
Measured: At pretraining
