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: Background Adopting clear guidelines for diagnosis and management of bronchial asthma could improve the medical care services administered to asthmatic patients. This can be reflected on amelioration of manifestations, decrease of attacks of asthma and hence decrease the medical burden of the disease. Objectives The current study was designed to evaluate the adherence of primary health care physicians to the recommendations of the National Protocol for Management of Asthma in Kuwait and the factors affecting this adoption, reveal their knowledge, attitude and practices about bronchial asthma, and identify barriers for caring of asthmatic patients. Subjects and methods The target population was primary health care physicians. All the primary health care physicians of two randomly selected health districts, out of five, were included. Out of 376 physicians available during the field period, 250 agreed to share in this study with an overall response rate of 66.5%. Results The results showed that only 37.2% of the studied primary health care physicians were adhering to asthma guidelines. Level of education, Knowledge about asthma, and clinical practice proved to be significant predictors of adherence to asthma guidelines. Although physicians had a high positive attitude toward asthma yet, they have poor knowledge and practice scores. The most common institutional barriers were improper follow up system and lack of spirometers, while heavy workload and lack of training were the main barriers related to health staff. Non compliance of patients to management and follow up schedules were on the top of barriers related to patients. Conclusion Physicians at the primary health care centers had a low adherence rate to asthma guidelines. Although they had high positive attitude toward asthma yet their knowledge and practice need improvement. To enhance adequate medical care to asthmatics; focus should be concentrated on increasing awareness and task based on job training of physicians as well as providing lung ventilation measuring equipment and improving the follow up system of bronchial asthma.Alexandria Journal of Medicine. 03/2014; 50(1):17–24.

ABSTRACT: Abstract Background: The characteristics of each inhalation maneuver when patients use dry powder inhalers (DPIs) are important, because they control the quality of the emitted dose. Methods: We have measured the inhalation profiles of asthmatic children [CHILD; n=16, mean forced expiratory volume in 1 sec (FEV1) 79% predicted], asthmatic adults (ADULT; n=53, mean predicted FEV1 72%), and chronic obstructive pulmonary disease (COPD; n=29, mean predicted FEV1 42%) patients when they inhaled through an Aerolizer, Diskus, Turbuhaler, and Easyhaler using their "real-life" DPI inhalation technique. These are low-, medium-, medium/high-, and high-resistance DPIs, respectively. The inhalation flow against time was recorded to provide the peak inhalation flow (PIF; in L/min), the maximum pressure change (ΔP; in kPa), acceleration rates (ACCEL; in kPa/sec), time to maximum inhalation, the length of each inhalation (in sec), and the inhalation volume (IV; in liters) of each inhalation maneuver. Results: PIF, ΔP, and ACCEL values were consistent with the order of the inhaler's resistance. For each device, the inhalation characteristics were in the order ADULT>COPD>CHILD for PIF, ΔP, and ACCEL (p<0.001). The results showed a large variability in inhalation characteristics and demonstrate the advantages of ΔP and ACCEL rather than PIFs. Overall inhaled volumes were low, and only one patient achieved an IV >4 L and ΔP >4 kPa. Conclusion: The large variability of these inhalation characteristics and their range highlights that if inhalation profiles were used with compendial in vitro dose emission measurements, then the results would provide useful information about the dose patients inhale during routine use. The inhalation characteristics highlight that adults with asthma have greater inspiratory capacity than patients with COPD, whereas children with asthma have the lowest. The significance of the inhaled volume to empty doses from each device requires investigation.Journal of Aerosol Medicine and Pulmonary Drug Delivery 05/2014; · 2.89 Impact Factor

ABSTRACT: Background: The management of Diabetes Mellitus and its important complication Diabetic Ketoacidosis is very crucial in today's world where the prevalence of Diabetes is very high. Medical students are the pillars of our future healthcare system and it is important to evaluate and update their knowledge and awareness regarding these both conditions. Materials and Methods: This study was a cross-sectional; Questionnaire based observational study conducted in a tertiary care hospital. The respondents were final year MBBS students of that college. Study instrument was a self developed, pre-validated, semi-structured questionnaire. Results: A total of 73 questionnaires were considered for analysis, giving a response rate of 90.12% with 43.83% and 56.16% were male and female respondents respectively. About 81.25% and 90.24% of male and female respondents gave correct answer to question related to the best indicator of glycemic control. Lack of knowledge was seen regarding the world Diabetes day. Approximately 37% of the respondent's parents were diabetic. Only 12 out of 73 respondents were aware about the factors leading to DKA.8 out of 73 were aware about investigations to be done in DKA. Around 43.84% of responders knew regarding the proper screening duration in person with risk of diabetes. Conclusion: From the study it was concluded that most of the students have basic knowledge regarding diabetes mellitus, its clinical features and management etc but only 50 % of the respondent were aware about DKA and further teaching and post teaching evaluation are needed in future direction.Journal of clinical and diagnostic research : JCDR. 04/2014; 8(4):HC04-6.
