Evaluation of a novel educational strategy, including inhaler-based reminder labels, to improve asthma inhaler technique

OBJECTIVE To evaluate the feasibility, acceptability and effectiveness of a brief intervention about inhaler technique, delivered by community pharmacists to asthma patients. METHODS Thirty-one pharmacists received brief workshop education (Active: n=16, CONTROL: n=15). Active Group pharmacists were trained to assess and teach dry powder inhaler technique, using patient-centered educational tools including novel Inhaler Technique Labels. Interventions were delivered to patients at four visits over 6 months. RESULTS At baseline, patients (Active: 53, CONTROL: 44) demonstrated poor inhaler technique (mean+/-S.D. score out of 9, 5.7+/-1.6). At 6 months, improvement in inhaler technique score was significantly greater in Active cf. CONTROL patients (2.8+/-1.6 cf. 0.9+/-1.4, p<0.001), and asthma severity was significantly improved (p=0.015). Qualitative responses from patients and pharmacists indicated a high level of satisfaction with the intervention and educational tools, both for their effectiveness and for their impact on the patient-pharmacist relationship. CONCLUSION A simple feasible intervention in community pharmacies, incorporating daily reminders via Inhaler Technique Labels on inhalers, can lead to improvement in inhaler technique and asthma outcomes. PRACTICE IMPLICATIONS Brief training modules and simple educational tools, such as Inhaler Technique Labels, can provide a low-cost and sustainable way of changing patient behavior in asthma, using community pharmacists as educators.

User error with Diskus and Turbuhaler by asthma patients and pharmacists in Jordan and Australia.

BACKGROUND: Use of inhalers requires accurate completion of multiple steps to ensure effective medication delivery. OBJECTIVE: To evaluate the most problematic steps in the use of Diskus and Turbuhaler for pharmacists and patients in Jordon and Australia. METHODS: With standardized inhaler-technique checklists, we asked community pharmacists to demonstrate the use of Diskus and Turbuhaler. We asked patients with asthma to demonstrate the inhaler (Diskus or Turbuhaler) they were currently using. RESULTS: Forty-two community pharmacists in Jordan, and 31 in Australia, participated. In Jordan, 51 asthma patients demonstrated use of Diskus, and 40 demonstrated use of Turbuhaler. In Australia, 53 asthma patients demonstrated use of Diskus, and 42 demonstrated use of Turbuhaler. RESULTS: The pharmacists in Australia had received inhaler-technique education more recently than those in Jordan (P = .03). With Diskus, few pharmacists in either country demonstrated correct technique for step 3 (exhale to residual volume) or step 4 (exhale away from the device), although there were somewhat fewer errors in Australia than Jordan (16% vs 0% in step 3, P = .007, and 20% vs 0% in step 4, P = .003 via chi-square test). With Turbuhaler there were significant differences between the pharmacists from Australia and Jordan, mainly in step 2 (hold the device upright while loading, 45% vs 2% correct, P < .001). Few of the patients had received inhaler-technique education in the previous year. The patients made errors similar to those of the pharmacists in individual steps with Diskus and Turbuhaler. The essential steps with Diskus were performed correctly more often by the Jordanian patients, and with Turbuhaler by the Australian patients. CONCLUSIONS: Despite differences in Jordans and Australias health systems, pharmacists from both Australia and Jordan had difficulty with the same Diskus and Turbuhaler steps. In both countries, the errors made by the asthma patients were similar to those made by the pharmacists.

Checklists for Powder Inhaler Technique: A Review and Recommendations

Turbuhaler and Diskus are commonly used powder inhaler devices for patients with respiratory disease. Their effectiveness is limited in part by a patients ability to use them correctly. This has led to numerous studies being conducted over the last decade to assess the correct use of these devices by patients and health care professionals. These studies have generally used device-specific checklists to assess technique, this being the most feasible and accessible method for assessment. However, divergence between the checklists and scoring systems for the same device in different studies makes direct comparison of results difficult and at times inappropriate. Little evidence is available to assess the relative importance of different criteria; however, brief patient training based on specific inhaler technique checklists leads to significant improvement in asthma outcomes. This paper reviews common checklists and scoring systems used for Turbuhaler and Diskus, discusses the problem of heterogeneity between different checklists, and finally recommends suitable checklists and scoring systems for these devices based on the literature and previous findings. Only when similar checklists are used across different research studies will accurate comparisons and meta-analysis be possible.

Exploring the role of quantitative feedback in inhaler technique education: a cluster-randomised, two-arm, parallel-group, repeated-measures study

Background:Feedback is a critical component of any educational intervention. When it comes to feedback associated with inhaler technique education, there is a lack of knowledge on its role or its potential to solve the major issue of poor inhaler technique.Aims:This study aims to explore the role of feedback in inhaler technique education and its impact on the inhaler technique of patients over time.Methods:A parallel-group, repeated-measures study was conducted in the community pharmacy in which the effectiveness of current best practice inhaler technique education utilising qualitative visual feedback (Group 1) was compared with a combination of qualitative and quantitative visual feedback (Group 2). The impact of these two interventions on inhaler technique maintenance was evaluated. Community pharmacists were randomly allocated to recruit people with asthma who were using a dry powder inhaler. At Visit 1 their inhaler technique was evaluated and education delivered and they were followed up at Visit 2 (1 month later).Results:Both educational interventions resulted in an increase in the proportion of patients with correct inhaler technique: from 4% to 51% in Group 1 and from 6% to 83% in Group 2 (Pearson’s Chi-Squared, P=0.03, n=49, and Pearson’s Chi-Squared, P=0.01, n=48, respectively). The magnitude of improvement was statistically significantly higher for Group 2 compared with Group 1 (n=97, P=0.02, Pearson’s Chi-Square test).Conclusions:The nature of feedback has an impact on the effectiveness of inhaler technique education with regard to correct inhaler technique maintenance over time.

The Effect of Using Simulation for Training Pharmacy Students on Correct Device Technique

Objective. To assess the effect of using simulation in pharmacy student training on correct device technique. Methods. A single-blinded, repeated measures, parallel group design study was conducted in 2011, involving all final-year pharmacy students in year 5 (final year) enrolled in the Clinical Pharmacy and Therapeutics course. Students were assessed on device technique at baseline based on previously published checklists for Diskus (DIS), Turbuhaler (TH), and pressurized Metered Dose Inhaler (pMDI). Students were randomly assigned to 2 groups: Intervention A, which included supervised hands-on education in groups and peer assessment/education; and Intervention B, which included supervised hands-on education in groups, peer assessment/education, and a simulated scenario counseling real asthma patients. The simulation involved groups of 6 students counseling 3 asthma patients on inhaler device technique. The counseling involved verbal information and physical demonstration until the patient performed all steps correctly. Student assessments on device technique were repeated 1 week postintervention. Results. At baseline, none of the students in Intervention A (n=54) or Intervention B (n=55) performed correct technique for any of the 3 devices. One week following the intervention, a significantly higher proportion of students in Intervention B demonstrated correct technique for the Diskus, Turbuhaler, and pMDI (60.0%, 70.9%, and 69.1%, respectively) than did students in Intervention A (27.8%, 40.7%, and 42.6%, respectively, p<0.005). Conclusion. Engaging pharmacy students with real asthma patients in a simulated scenario involving correct device technique education resulted in better device technique demonstration skills among students.

Associations between inhaler technique and asthma control among asthma patients using pressurised MDIs and DPIs.

OBJECTIVES To investigate associations between technique with pressurised metered-dose inhalers (pMDIs) and dry powder inhalers (DPIs) used as controller medication and asthma control variables measured using Asthma Control Test (ACT) scores. DESIGN In this cross-sectional study, the inhaler technique of asthma patients using pMDIs or DPIs (Turbuhaler® [TH] and Accuhaler Diskus™ [ACC]) were assessed against published inhaler technique checklists. ACT scores (maximum 25, higher score corresponding to better asthma control) were assessed. RESULTS Of the 130 subjects enrolled in the study (41 TH, 54 ACC and 35 pMDI), inhaler technique scores (out of nine for all devices) were low for TH (4.4 ± 0.9) and ACC (5.4 ± 1.0) compared with pMDI (8.1 ± 0.9) (P < 0.001, one-way analysis of variance). Older age and use of pMDI were associated with better inhaler technique. ACT scores were low, consistent with very poorly controlled asthma (mean TH 13.1 ± SD 3.9, mean ACC 13.3 ± SD 3.9 and mean pMDI 12.8 ± SD 4.2). No significant association between inhaler technique scores and ACT scores was found. More recent asthma diagnosis and a higher level of education were associated with higher ACT scores (better asthma control). CONCLUSION Asthma control was poor in this population. Lack of a significant association between the inhaler technique score and asthma control may reflect the multiple factors contributing to poor asthma control in the Jordanian population.

Associations between patient factors and medication adherence: A Jordanian experience

Objective: To explore the effect of patient characteristics and health beliefs on their medication adherence. Methods: Patients (n=167) with chronic conditions (mean age 58.9; SD=13.54, 53% males) were recruited from March 2009- to March 2010 using a cross sectional study design. Data collected included patients’ demographics, medical conditions, medications therapeutic regimen, frequency of physician visits and health beliefs. Patient self-reported adherence to medications was assessed by the researcher using a validated and published scale. Treatment related problems (TRPs) were evaluated for each patient by competent clinical pharmacists. Associations between patient characteristics/health beliefs with adherence were explored. Results: About half of the patients (46.1%) were non-adherent. A significant association was found between lower adherence and higher number of disease states (p<0.001), higher number of medications (p=0.001), and higher number of identified TRPs (p = 0.003). Patient adherence was positively affected by older age, higher educational level, and higher number of physician visits per month, while it was negatively affected by reporting difficulties with getting prescription refills on time. Conclusion: This study identified different factors that may negatively affect adherence, including higher number of medications and disease states, higher number of identified TRPs and inability to getting prescription refills on time. Hence, more care needs to be provided to patients with complex therapeutic regimens in order to enhance adherence.

Effect of novel inhaler technique reminder labels on the retention of inhaler technique skills in asthma: a single-blind randomized controlled trial

Inhaler technique can be corrected with training, but skills drop off quickly without repeated training. The aim of our study was to explore the effect of novel inhaler technique labels on the retention of correct inhaler technique. In this single-blind randomized parallel-group active-controlled study, clinical pharmacists enrolled asthma patients using controller medication by Accuhaler [Diskus] or Turbuhaler. Inhaler technique was assessed using published checklists (score 0–9). Symptom control was assessed by asthma control test. Patients were randomized into active (ACCa; THa) and control (ACCc; THc) groups. All patients received a “Show-and-Tell” inhaler technique counseling service. Active patients also received inhaler labels highlighting their initial errors. Baseline data were available for 95 patients, 68% females, mean age 44.9 (SD 15.2) years. Mean inhaler scores were ACCa:5.3 ± 1.0; THa:4.7 ± 0.9, ACCc:5.5 ± 1.1; THc:4.2 ± 1.0. Asthma was poorly controlled (mean ACT scores ACCa:13.9 ± 4.3; THa:12.1 ± 3.9; ACCc:12.7 ± 3.3; THc:14.3 ± 3.7). After training, all patients had correct technique (score 9/9). After 3 months, there was significantly less decline in inhaler technique scores for active than control groups (mean difference: Accuhaler −1.04 (95% confidence interval −1.92, −0.16, P = 0.022); Turbuhaler −1.61 (−2.63, −0.59, P = 0.003). Symptom control improved significantly, with no significant difference between active and control patients, but active patients used less reliever medication (active 2.19 (SD 1.78) vs. control 3.42 (1.83) puffs/day, P = 0.002). After inhaler training, novel inhaler technique labels improve retention of correct inhaler technique skills with dry powder inhalers. Inhaler technique labels represent a simple, scalable intervention that has the potential to extend the benefit of inhaler training on asthma outcomes.Asthma: Reminder labels improve inhaler techniquePersonalized labels on asthma inhalers remind patients of correct technique and help improve symptoms over time. Iman Basheti at the Applied Science Private University in Jordan and co-workers trialed the approach of placing patient-specific reminder labels on dry-powder asthma inhalers to improve long-term technique. Poor asthma control is often exacerbated by patients making mistakes when using their inhalers. During the trial, 95 patients received inhaler training before being split into two groups: the control group received no further help, while the other group received individualized labels on their inhalers reminding them of their initial errors. After three months, 67% of patients with reminder labels retained correct technique compared to only 12% of controls. They also required less reliever medication and reported improved symptoms. This represents a simple, cheap way of tackling inhaler technique errors.
