Development and Validation of a Patient Satisfaction and Preference Questionnaire for Inhalation Devices

Abstract

Our analyses across asthma, COPD and patients with mixed respiratory disease (with features of both COPD and asthma), study designs and data sets lead us to conclude that the PASAPQ is a practical, valid, reliable and responsive instrument for measuring respiratory device satisfaction. Furthermore, a difference in satisfaction scores between treatment groups of 10 points is, conservatively, a difference that is meaningful to patients.

The Global Usability Score: A Novel Comprehensive Tool for Assessing, Ranking, and Compare Usability of Inhalers in Patients Requiring Airway Treatments

“…In 2005, the Patient Satisfaction and Preference Questionnaire (PASAPQ), such as a multiitem measure tool to be administered to asthma and COPD patients, was designed and validated in order to assess both the performance and the convenience of inhalers, together to the overall patients' satisfaction [17]. Even if the questionnaire proved to be a practical and reliable instrument of investigation, it should be pointed out that it only consents to measure the patients' personal beliefs on the inhalers to compare [17,24,25], being unfortunately the objective check and the control of responses by an independent third-part expert observer (i.e. the expert nurse) lacking.…”

“…Another self-administered questionnaire was used for assessing the performance of a novel DPI [17]. This questionnaire consists of twenty questions belonging to four different domains of patients' beliefs (confidence; ease-of-use, preference, and satisfaction of the device).…”

“…In particular, the determinants of patients' incorrect inhalation procedures [7,8] and those of patients' preference, acceptance, and satisfaction focused the attention of the majority of researchers [9][10][11][12][13][14][15]. The primary role of patients' viewpoint was then highly valued in recent years, even if the attempts to quantify objectively the correspondence between patients' beliefs and real usability in real life by means of specific instruments were only episodically pursued [11,[16][17][18][19].…”

New abilities of administration of tiotropium bromide using the aerosol delivery device Respimat®

“…Чаще всего в данных исследова ниях были использованы произвольные опросники, не учитывающие основ психометрического тестиро вания [37]. Поэтому особое внимание среди таких работ привлекают исследования, в которых были использованы более совершенные инструменты, в частности Опросник удовлетворенности и пред почтений пациента (Patient Satisfaction and Preference Questionnaire -PASAPQ), который является прак тичным валидизированным, надежным и чувстви тельным инструментом для тестирования отноше ния пациента к ингаляционную устройству [38]. В исследовании W. Schurmann et al (n = 224) с по мощью PASAPQ было проведено сравнение пред почтений больных ХОБЛ и БА при применении ин галяторов Респимат ® и ДАИ [35].…”

Patient preference for and satisfaction with inhaler devices

“…Only two questionnaires were developed by outcomes experts and then tested in the field: the PDEA and the PASAPQ [20,25]. Only the PASAPQ has a published validation, which includes a determination of minimally important difference, a very important feature for discriminating the degree of difference that is clinically significant [33].…”
