“…However, the participants might intentionally have skipped this step, since they knew they were using placebo inhalers and therefore did not think they needed to check the dose counter. Concerning the distribution of critical steps, two of four critical errors for MDIs were related to breathing, a common mistake also found in other studies [ 29 ]. Nevertheless, no clear pattern could be seen overall.…”

Background Metered dose inhalers (MDIs) and dry powder inhalers (DPIs) are devices used for the treatment of asthma and chronic obstructive pulmonary disease (COPD). Inhaler technique is important since incorrect technique can lead to a poorer prognosis and hospitalization. Objective The objective of this study was to investigate the inhaler technique and overall adherence to medications in an adult population with asthma and COPD. Patients and Methods Those invited to participate were people admitted to Umeå University Hospital in northern Sweden in October, November and December 2018, with inhaled medication prescribed prior to admission. Inhaler technique was assessed using checklists and observations with placebo-inhalers were conducted. The Medication Adherence Report Scale (MARS)-5 was used to measure self-reported overall adherence to drug medication. Results Of the 23 people included in the study, 26.1% had one or more critical errors in inhaler technique and 30.4% were considered overall non-adherent to drug medication. Among the 23 participants, the mean age, and the number of regularly prescribed medications were higher among those with poor inhaler technique than among people with no error in their inhaler technique. Conclusion This study indicates that poor inhaler technique and overall non-adherence to medications occur among hospitalised people with asthma and COPD living in northern Sweden. Interventions to improve inhaler technique and adherence to drugs are needed.

“…The effective management of chronic constrictive pulmonary conditions lies, mainly, in the proper and timely administration of medication. However, as recently reported [2], a large proportion of patients use their inhalers incorrectly. Studies have shown that possible technique errors can have an adverse impact on clinical outcome for users of inhaler medication [3,4].…”

Effective management of chronic constrictive pulmonary conditions lies in proper and timely administration of medication. As a series of studies indicates, medication adherence can effectively be monitored by successfully identifying actions performed by patients during inhaler usage. This study focuses on the recognition of inhaler audio events during usage of pressurized metered dose inhalers (pMDI). Aiming at real-time performance, we investigate deep sparse coding techniques including convolutional filter pruning, scalar pruning and vector quantization, for different convolutional neural network (CNN) architectures. The recognition performance has been assessed on three healthy subjects following both within and across subjects modeling strategies. The selected CNN architecture classified drug actuation, inhalation and exhalation events, with 100%, 92.6% and 97.9% accuracy, respectively, when assessed in a leave-one-subject-out cross-validation setting. Moreover, sparse coding of the same architecture with an increasing compression rate from 1 to 7 resulted in only a small decrease in classification accuracy (from 95.7% to 94.5%), obtained by random (subject-agnostic) cross-validation. A more thorough assessment on a larger dataset, including recordings of subjects with multiple respiratory disease manifestations, is still required in order to better evaluate the method's generalization ability and robustness.

“…This kind of attitude appears to create a disconnect between inhaler technique theory and practice, as mastery at the time of teaching does not translate into the maintenance of correct inhaler technique over time [15]. We recognize that, for the patient, there is a range of competing factors that impact their willingness, ability, and preference to using their inhalers [16][17], but we believe they can be trained successfully to use their inhalers with effective and repeated instruction [9][10][11][12][13][14][15][16][17][18].…”

Background Inhaled medications are the main therapeutic treatment of chronic obstructive pulmonary disease (COPD) and inhaler technique remained important that can increase medication efficacy, reducing dose and side effects. Poor inhaler technique is multi-factorial and the quality of inhaler technique has not previously assessed in Pakistan. We conducted a study to examine a range of competing factors that impact COPD patient willingness, practices, and preference in using their inhalers. Methods A cross-sectional of 765 patients with COPD were interviewed and assessed by qualitative questionnaires. Objective inhalation technique and steps assessment was performed; satisfaction, preferences, perception, and practice of different types of inhaler devices were evaluated at a single crosssectional visit at the study enrolment. Results The study included 765 participants of mean age 58.7 years (SD ±7.8); 32% males and 68% females. Almost all of the females were exposed to biomass fuel smoke exposure (99%) and pipe (Huka) smokers 53%, while most male participants were cigarette smokers (92%). Only 6.3% of participants were able to perform correct steps of inhaler use, and few educated patients completed 7-steps. 66% of patients were using dry powder inhalers (DPI) inhaler devices and mostly performed the steps 1, 2, and 4 (98%) correctly, while 44% who were using metered-dose inhalers (MDI) completed only steps 2 and 4 correctly (88%). The majority of participants reported the particular inhaler devices was prescribed by the visiting consultants (54%). Interestingly, they were using two inhalers together (47%) relieving symptoms of dyspnea (83%) and cough (73%). The inhaler use technique was demonstrated to most of the patients by the pharmacy salesman (38.4%), while 15.8% reported that their doctors taught them the inhaler technique. 54.2% reported reason for poor adherence to inhaler use as they understand it might not work lately and 75.2% were not aware of any side effects associated with the regular use of an inhaler. Conclusions Poor inhaler technique is highly prevalent and the associated errors did not appear to be dependent on device type. Most of the participants had not receive proper training about the correct use and were not involved in decision making about the choice of inhaler device.
