Effect of Nurse-Led Spirometry Demonstration on Patient Confidence and Technique Accuracy Among First-Time COPD Diagnosed Adults: A Quasi-Experimental Study

Background: Spirometry is very important in the management of chronic obstructive pulmonary disease (COPD); however, newly diagnosed patients lack confidence and technique in using it. Improper performance may lead to misinterpretation and mismanagement. Nurse-led educational interventions are increasingly identified with the role they play in enhancing patient outcomes, through outlined teaching and hands-on guidance. Aim: This study aimed to determine the effect on confidence and the accuracy of technique in adults with newly diagnosed COPD of a nurse-led spirometry demonstration. Methodology: A quasi-experimental study was conducted on 60 first-time spirometry patients at Hayatabad Medical Complex, Peshawar, divided into experimental and control groups. The experimental group received a nurse-led demonstration; the control group received standard verbal instructions. Confidence and technique accuracy were assessed using a Likert scale and ATS checklist, with data analyzed via t-tests in the Statistical Package for the Social Sciences (SPSS) v27. Results: The experimental group reported significant enhancement in confidence (mean difference +1.7, p < 0.001) and technique accuracy (mean difference +2.2, p < 0.001) from the control group that reported minimal and statistically unimportant variations. Conclusion: Demonstrations that are nurse-led can do a lot to improve the confidence and accuracy of COPD patients who are newly diagnosed with spirometry. It is possible to improve the diagnostic precision as well as increase patient engagement if such interventions are incorporated into standard medical care.
