Introduction:Greater patient satisfaction with his or her inhalation device is associated with better adherence to pharmacological therapy and better clinical outcomes, such as improved quality of life, greater asthma control and fewer exacerbations. Objective: To determine the satisfaction level of a group of patients diagnosed with bronchial asthma with respect to their devices for inhalation of bronchodilators and glucocorticoids. Methods: This was a cross-sectional study of patients treated in the Colombian health system. Satisfaction with inhalation devices was evaluated with the FSI-10 instrument (Evaluation of Satisfaction with the Inhaler). A score of ≥ 44 points indicated high satisfaction. Results: In total, 362 patients from 59 cities were identified, their median age was 55 years, and 74.6% were women. The average score was 44.6; 68.5% of patients showed high satisfaction, especially with metered-dose inhalers, and 63.4% did not use them with an inhalocamera. Users of metered-dose inhalers (OR: 1.80; 95% CI: 1.05–3.10) and those who received training by medical specialists (OR: 2.29; 95% CI: 1.33–3.97) had high satisfaction, while patients who were older (40–64 vs. <40 years: OR: 0.38; 95% CI: 0.19–0.78 and ≥ 65 vs. <40 years: OR: 0.35; 95% CI: 0.15–0.81), resided in the Caribbean region (OR: 0.48; 95% CI: 0.29–0.81) and had a university education (OR: 0.54; 95% CI: 0, 32–0.90) had lower satisfaction. Conclusions: The majority of patients with asthma used metered-dose inhalers without an inhalocamera, and their overall satisfaction was higher than that of patients using other inhalation devices. Patients who received special training from medical specialists showed better satisfaction.

OBJECTIVE: To evaluate inhaler technique in outpatients with asthma and to determine associations between the correctness of that technique and the level of asthma control. METHODS: This was a cross-sectional study involving patients > 14 years of age with physician-diagnosed asthma. The patients were recruited from the Asthma Outpatient Clinic of the Hospital de Clínicas de Porto Alegre, in the city of Porto Alegre, Brazil. The patients completed two questionnaires (a general questionnaire and an asthma control questionnaire based on the 2011 Global Initiative for Asthma guidelines), demonstrated their inhaler technique, and performed pulmonary function tests. Incorrect inhaler technique was defined as the incorrect execution of at least two of the predefined steps. RESULTS: We included 268 patients. Of those, 81 (30.2%) showed incorrect inhaler technique, which was associated with poor asthma control (p = 0.002). Logistic regression analysis identified the following factors associated with incorrect inhaler technique: being widowed (OR = 5.01; 95% CI, 1.74-14.41; p = 0.003); using metered dose inhalers (OR = 1.58; 95% CI, 1.35-1.85; p < 0.001); having a monthly family income < 3 times the minimum wage (OR = 2.67; 95% CI, 1.35-1.85; p = 0.008), and having > 2 comorbidities (OR = 3.80; 95% CI, 1.03-14.02; p = 0.045). CONCLUSIONS: In the sample studied, incorrect inhaler technique was associated with poor asthma control. Widowhood, use of metered dose inhalers, low socioeconomic level, and the presence of > 2 comorbidities were associated with incorrect inhaler technique.

AbstractObjective: To validate two scores quantifying the ability of patients to use metered dose inhalers (MDIs) or dry powder inhalers (DPIs); to identify the most common errors made during their use; and to identify the patients in need of an educational program for the use of these devices.Methods: This study was conducted in three phases: validation of the reliability of the inhaler technique scores; validation of the contents of the two scores using a convenience sample; and testing for criterion validation and discriminant validation of these instruments in patients who met the inclusion criteria.Results: The convenience sample comprised 16 patients. Interobserver disagreement was found in 19% and 25% of the DPI and MDI scores, respectively. After expert analysis on the subject, the scores were modified and were applied in 72 patients. The most relevant difficulty encountered during the use of both types of devices was the maintenance of total lung capacity after a deep inhalation. The degree of correlation of the scores by observer was 0.97 (p < 0.0001). There was good interobserver agreement in the classification of patients as able/not able to use a DPI (50%/50% and 52%/58%; p < 0.01) and an MDI (49%/51% and 54%/46%; p < 0.05).Conclusions: The validated scores allow the identification and correction of inhaler technique errors during consultations and, as a result, improvement in the management of inhalation devices.

Transdermal Route

The intranasal and intrapulmonary routes are simple, do not necessarily require any specialized equipment, and can be used by both patients and their non-professional caregivers. Intranasal administration may be associated with rapid onset of analgesia. A number of fentanyl-based formulations are commercially available to manage breakthrough cancer pain. Intranasal opioids can be delivered by traditional spray bottles, and also by syringes fitted with atomisers. The intrapulmonary route has the potential for rapid onset of analgesia. and can be delivered by traditional nebulizers, and other inhalation devices (e.g. metered dose inhalers, dry powder inhalers). The transdermal route has less potential for rapid onset of analgesia. However, new patch technology (iontophoretic technology) may alter the current position.

Due to the increasing worldwide incidence of asthma, a growing usage of inhalation devices has been observed. Some of the pressurized Metered Dose Inhalers (pMDI) limitations have been overcome by the introduction of newly and improved Valved Holding Chambers (VHC), resulting in good patient acceptance. The efficiency is assessed by the VHC Emitted Dose (ED), i.e. the amount of drug available to the patient. Using the pMDI salbutamol sulfate formulation (Ventolin® HFA-134a) as the test drug, several VHC devices were assessed. These latest were grouped by material characteristics: dissipative (OptiChamber Diamond®, AeroChamber Plus®, Vortex®, A2A Spacer®), non-dissipative (SpaceChamber Plus®, Compact SpaceChamber Plus®, Volumatic®) and stainless steel (Nebuchamber®). The pMDI + VHC were assembled to a filter housing, which comprises an induction port with similar USP Throat dimensions, and connected to a vacuum pump (calibrated at 15, 26 and 40 L/min). Using UV-Vis Spectrophotometry equipment at 244 nm, it was possible to determine its concentration for later mass calculation. For all the VHC devices tested, the total mass recovery percentage was between 85% and 120%. At 26 L/min, the Vortex® VHC has shown the highest ED (47.3 ± 1.8 %). The ED may not be dependent on the volume of the VHC. Although, further analysis of the results suggests the existence of a linear correlation between the ED and the VHC body length. SpaceChamber Plus® results show an increase of the ED and, subsequently, a decrease in VHC deposition fraction, with the increase of airflow.

In the 1990s, metered dose inhalers (MDIs) containing chlorofluorocarbons were replaced with dry-powder inhalers (DPIs) and MDIs containing hydrofluorocarbons (HFCs). While HFCs are not ozone depleting, they are potent greenhouse gases. Annual carbon footprint (CO2e), per patient were 17 kg for Relvar-Ellipta/Ventolin-Accuhaler; and 439 kg for Seretide-Evohaler/Ventolin-Evohaler. In 2017, 70% of all inhalers sold in England were MDI, versus 13% in Sweden. Applying the Swedish DPI and MDI distribution to England would result in an annual reduction of 550 kt CO2e. The lower carbon footprint of DPIs should be considered alongside other factors when choosing inhalation devices.

Objective The objective of this study is to evaluate patient and provider satisfaction with telemedicine encounters across 3 otolaryngology practices. Study Design Cross-sectional survey. Setting A military community hospital, an academic military hospital, and a nonmilitary academic center. Methods A telephone-based survey of patients undergoing telemedicine encounters for routine otolaryngology appointments was performed between April and July 2020. Patients were asked about their satisfaction, the factors affecting care, and demographic information. A provider survey was emailed to staff otolaryngologists. The survey asked about satisfaction, concerns for reimbursement or liability, encounters best suited for telemedicine, and demographic information. The results were analyzed with descriptive statistics and a multivariable logistic linear regression model to determine odds ratios. Results A total of 325 patients were surveyed, demonstrating high satisfaction with telemedicine (average score, 4.49 of 5 [best possible answer]). Patients perceived “no negative impact” or “minor negative impact” on the encounter due to the lack of a physical examination or face-to-face interaction (1.86 and 1.95 of 5, respectively). High satisfaction was consistent across groups for distance to travel, age, and reason for referral. A total of 25 providers were surveyed, with an average satisfaction score of 3.44 of 5. Providers reported “slight” to “somewhat” concern about reimbursement (40%) and liability (32%). Conclusion Given patients’ and providers’ levels of satisfaction, there is likely a role for telemedicine in otolaryngology practice that may benefit patient care independent of the COVID-19 pandemic.
