The potential of a 2Tone Trainer to help patients use their metered-dose inhalers.
ABSTRACT Many patients have problems using the correct inhalation technique when they use their metered-dose inhalers (MDIs). We have investigated whether a training aid (2Tone Trainer [2T]; Canday Medical Ltd; Newmarket, UK) helps to maintain the correct inhaler technique after patients leave the clinic
Ethics committee approval was obtained, and patients gave consent. Asthmatic patients who had been prescribed an MDI had their inhalation technique assessed. Their peak inhalation flow (PIF) when using their MDI, FEV(1), and the Juniper asthma quality of life questionnaire (AQLQ) score were measured. Those patients using the recommended MDI technique were the good-technique (GT) group. The remainder were randomized to receive verbal training (VT) or VT plus the 2T to improve their MDI technique. All patients returned 6 weeks later.
There were 36, 35, and 36 asthmatic patients, respectively, who completed the GT, VT, and 2T procedures. FEV1 did not change within all groups between visit 1 and 2. PIF and AQLQ score did not change in the GT group. In the VT and 2T groups, the AQLQ score increased by mean differences of 0.33 (95% confidence interval [CI], 0.14 to 0.53; p < 0.001) and 0.74 (95% CI, 0.62 to 0.86; p < 0.001). At visit 1, all patients in the VT and 2T groups inhaled > 90 L/min decreasing to 12 patients and 1 patient, respectively, at visit 2 (p < 0.001 both groups). The overall changes in the 2T group for PIF and AQLQ score, between visits 1 and 2, were significantly (p < 0.001) greater than the corresponding changes in the VT group.
The 2T helps patients to maintain the recommended MDI technique posttraining with improvements in AQLQ score.

ABSTRACT: The number of people with asthma continues to grow around the world, and asthma remains a poorly controlled disease despite the availability of management guidelines and highly effective medication. Patient noncompliance with therapy is a major reason for poor asthma control. Patients fail to comply with their asthma regimen for a wide variety of reasons, but incorrect use of inhaler devices is amongst the most common. The pressurised metered-dose inhaler (pMDI) is still the most frequently used device worldwide, but many patients fail to use it correctly, even after repeated tuition. Breath-actuated inhalers are easier to use than pMDIs. The rationale behind inhaler choice should be evidence based rather than empirical. When choosing an inhaler device, it is essential that it is easy to use correctly, dosing is consistent, adequate drug is deposited in both central and peripheral airways, and that drug deposition is independent of airflow. Regular checking of inhalation technique is crucial, as correct inhalation is one of the cornerstones of successful asthma management.ISRN allergy. 01/2013; 2013:102418.

ABSTRACT: Asthma is a prevalent and costly disease resulting in reduced quality of life for a large proportion of individuals. Effective patient self-management is critical for improving health outcomes. However, key aspects of self-management such as self-monitoring of behaviours and symptoms, coupled with regular feedback from the health care team, are rarely addressed or integrated into ongoing care. Health information technology (HIT) provides unique opportunities to facilitate this by providing a means for two way communication and exchange of information between the patient and care team, and access to their health information, presented in personalized ways that can alert them when there is a need for action. The objective of this study is to evaluate the acceptability and efficacy of using a web-based self-management system, My Asthma Portal (MAP), linked to a case-management system on asthma control, and asthma health-related quality of life. The trial is a parallel multi-centered 2-arm pilot randomized controlled trial. Participants are randomly assigned to one of two conditions: a) MAP and usual care; or b) usual care alone. Individuals will be included if they are between 18 and 70, have a confirmed asthma diagnosis, and their asthma is classified as not well controlled by their physician. Asthma control will be evaluated by calculating the amount of fast acting beta agonists recorded as dispensed in the provincial drug database, and asthma quality of life using the Mini Asthma Related Quality of Life Questionnaire. Power calculations indicated a needed total sample size of 80 subjects. Data are collected at baseline, 3, 6, and 9 months post randomization. Recruitment started in March 2010 and the inclusion of patients in the trial in June 2010. Self-management support from the care team is critical for improving chronic disease outcomes. Given the high volume of patients and time constraints during clinical visits, primary care physicians have limited time to teach and reinforce use of proven self-management strategies. HIT has the potential to provide clinicians and a large number of patients with tools to support health behaviour change.

ABSTRACT: Asthma and chronic obstructive pulmonary disease are both common conditions with an increasing prevalence worldwide. Inhaled therapy for these conditions has a number of advantages over systemic therapy, including reduced side effects and quicker onset of action. The effective use of inhaled therapy is critically dependent upon the nature of the drug-delivery system and the ability of the patient to use the system correctly. There are a wide number of inhaler devices on the market, each with positive and negative aspects. A crucial part of patient care is to ensure that the choice of inhaler device for the individual is an effective therapy. There are a number of interventions that can help with the choice of inhaler device and also improve the ability of the patient to use inhaled therapy. Inhaler technique training needs to be a cornerstone of the care of patients with asthma or chronic obstructive pulmonary disease to ensure optimal therapy.Expert Review of Respiratory Medicine 02/2012; 6(1):91-101; quiz 102-3.
