Project description:BACKGROUND:Older adults recently discharged from the hospital are known to be at risk of functional decline and falls. This study evaluated the effect of a tailored education program provided in the hospital on older adult engagement in fall prevention strategies within 6 months after hospital discharge. METHODS:A process evaluation of a randomized controlled trial that aimed to improve older adult fall prevention behaviors after hospital discharge. Participants (n = 390) were aged 60 years and older with good cognitive function (greater than 7 of 10 Abbreviated Mental Test Score), discharged home from three hospital rehabilitation wards in Perth, Australia. The primary outcomes were engagement in fall prevention strategies, including assistance with daily activities, home modifications, and exercise. Data were analyzed using generalized linear modeling. RESULTS:There were 76.4% (n = 292) of participants who completed the final interview (n = 149 intervention, n = 143 control). There were no significant differences between groups in engagement in fall prevention strategies, including receiving instrumental activity of daily living (IADL) assistance (adjusted odds ratio [AOR] = 1.3 [95% confidence interval {CI} = 0.7-2.1]; P = .3), completion of home modifications (AOR = 1.2 [95% CI = 0.7-1.9]; P = .4), and exercise (AOR = 1.3 [95% CI = 0.7-2.2]; P = .3). There was a high proportion of unmet ADL needs within both groups, and levels of participant dependency remained higher at 6 months compared to baseline levels at admission. The proportion of all participants who engaged in exercise following hospital discharge increased by 30%; however, the mean duration of exercise reduced from 3 hours per week at baseline to 1 hour per week at 6-month follow-up (SD = 1.12 hours per week). CONCLUSION:Tailored education did not increase older adult engagement in fall prevention strategies after hospital discharge compared to usual care. Further research is required to evaluate older adults' capacity to change their behaviors once they return home from hospital, which may enable a safer recovery of their independence.

Project description:ObjectivesTo explore whether an association exists between health care professionals' (HCPs) asthma knowledge and inhaler technique demonstration skills.MethodsHCPs' asthma knowledge and inhaler technique demonstration skills were assessed at baseline at an inter-professional educational workshop focusing on asthma medication use. Asthma knowledge was assessed via a published questionnaire. Correct inhaler technique for the three inhalers, the Accuhaler, Turbuhaler and pressurized Metered Dose Inhaler (pMDI) was assessed using published checklists.ResultsTwo hundred HCPs agreed to participate: 10 specialists (medical doctors specialized in respiratory diseases) (5%), 46 general practitioners (23%), 79 pharmacists (39%), 15 pharmacists' assistants (8%), 40 nurses (20%) and 10 respiratory therapists (5%). Backwards stepwise multiple regression conducted to determine predictors of HCPs' inhaler technique, showed that out of many independent variables (asthma knowledge score, profession, age, gender, place of work, years in practice and previous personal use of the study inhaler/s), asthma knowledge score was the only variable showing significant association with inhaler technique (R(2)=0.162, p<0.001).ConclusionThis study revealed significant associations between asthma knowledge and inhaler technique scores for all HCPs. Providing inter-professional workshops for all HCPs involved integrating education on asthma knowledge and practice of inhaler technique skills are looked-for.

Project description: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.This study aims to explore the role of feedback in inhaler technique education and its impact on the inhaler technique of patients over time.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).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).The nature of feedback has an impact on the effectiveness of inhaler technique education with regard to correct inhaler technique maintenance over time.

Project description:We performed a cross-sectional study within a specialised respiratory inpatient unit assessing 25 nurses' [85% female, 8.0 ± 7.9 (mean ± SD) years' experience in nursing] confidence in providing inhaler device education using a self-reported questionnaire, and their competency (% correct steps) in using eight different inhaler devices. Sixteen percent of participants were 'not confident' providing inhaler education, while 84% were 'moderately' or 'extremely' confident. The mean (±SD)% correct steps for all devices was 47 ± 17%. There was no correlation between % correct steps and nursing years (r = 0.21, p = 0.31), or 'confidence' with providing inhaler education (r = 0.02, p = 0.91) but % correct steps strongly correlated with number of individual device prescriptions within the hospital in the preceding year (r = 0.78, p = 0.039). Most respiratory nurses felt confident in teaching inhaler technique but their overall demonstrated ability to correctly use inhalers was poor, especially for less frequently prescribed devices within our hospital. Regular assessment and ongoing education on correct inhaler technique for respiratory nurses is necessary to optimise all device usage by nurses, irrespective of experience or confidence.

Project description:Serious inhaler technique errors can impair drug delivery to the lungs. This randomised, crossover, open-label study evaluated the proportion of patients making predefined serious errors with Pulmojet compared with Diskus and Turbohaler dry powder inhalers.Patients ?18 years old with asthma and/or COPD who were current users of an inhaler but naïve to the study devices were assigned to inhaler technique assessment on Pulmojet and either Diskus or Turbohaler in a randomised order. Patients inhaled through empty devices after reading the patient information leaflet. If serious errors potentially affecting dose delivery were recorded, they repeated the inhalations after watching a training video. Inhaler technique was assessed by a trained nurse observer and an electronic inhalation profile recorder.Baseline patient characteristics were similar between randomisation arms for the Pulmojet-Diskus (n?=?277) and Pulmojet-Turbohaler (n?=?144) comparisons. Non-inferiority in the proportions of patients recording no nurse-observed serious errors was demonstrated for both Pulmojet versus Diskus, and Pulmojet versus Turbohaler; therefore, superiority was tested. Patients were significantly less likely to make ?1 nurse-observed serious errors using Pulmojet compared with Diskus (odds ratio, 0.31; 95 % CI, 0.19-0.51) or Pulmojet compared with Turbohaler (0.23; 0.12-0.44) after reading the patient information leaflet with additional video instruction, if required.These results suggest Pulmojet is easier to learn to use correctly than the Turbohaler or Diskus for current inhaler users switching to a new dry powder inhaler.ClinicalTrials.gov Identifier: NCT01794390 (February 14, 2013).

Project description:INTRODUCTION:Chronic Obstructive Pulmonary Disease (COPD)and asthma affect more than 10% of the population. Most patients use their inhaler incorrectly, mainly the elderly, thereby becoming more susceptible to poor clinical control and exacerbations. Placebo device training is regarded as one of the best teaching methods, but there is scarce evidence to support it as the most effective one to improve major clinical outcomes. Our objective is to perform a single-blinded RCT to assess the impact of this education tool in these patients. METHODS AND ANALYSIS:A multicentre single-blinded Randomised Controlled Trial (RCT) will be set up, comparing an inhaler education programme with a teach-to-goal placebo-device training versus usual care, with a 1-year follow-up, in patients above 65 years of age with asthma or COPD. Intervention will be provided at baseline, and after 3 and 6 months, with interim analysis at an intermediate time point. Exacerbation rates were set as primary outcomes, and quality of life, adherence rates, clinical control and respiratory function were chosen as secondary outcomes. A sample size of 146 participants (73 in each arm) was estimated as adequate to detect a 50% reduction in event rates. Two-sample proportions ?² test will be used to study primary outcome and subgroup analysis will be carried out according to major baseline characteristics. ETHICS AND DISSEMINATION:Every participant will sign a written consent form. A Data Safety Monitoring Board will be set up to evaluate data throughout the study and to monitor early stopping criteria. Identity of all participants will be protected. This protocol was approved on 22 November 2017 by the local Ethics Committee of University of Beira Interior, with the reference number CE-UBI-Pj-2017-025. Results will be presented in scientific meetings and published in peer-reviewed journals. TRIAL REGISTRATION NUMBER:NCT03449316; Pre-Results.

Project description:IntroductionGeneric substitution of inhaler devices is a relatively new phenomenon. The best patient outcomes associated with generic substitution occur when prescribers obtain consent from their patients to prescribe a generic inhaler and also teach their patient how to correctly use the new device. To date, no prospective observational study has assessed the level of training required for general practitioners (GPs) to demonstrate correct inhaler technique using two dry powder inhaler devices delivering fixed-dose combination budesonide/formoterol therapy. This study aims to (1) determine the level of training required for GPs to master and maintain correct IT when using two different dry powder inhalers that are able to be substituted in clinical practice and (2) determine the number and types of errors made by GPs on each device and inhaler device preference at each training visit.MethodA randomized, parallel-group cross-over study design was used to compare the inhaler technique of participants with a Spiromax® placebo device and a Turbuhaler® placebo device. This study consisted of two visits with each participant over a period of 4 ± 1 weeks (visit 1 and visit 2). A total of six levels of assessment and five levels of training were implemented as required. Level 1, no instruction; level 2, following use of written instruction; level 3, following viewing of instructional video; level 4, expert tuition from the researcher; level 5/level 6, repeats of expert tuition from the researcher when required. Participants progressed through each level and stopped at the point at which they demonstrated device mastery. At each level, trained researchers assessed the inhaler technique of the participants. Participants were also surveyed about their previous inhaler use and training.ResultsIn total, 228 GPs participated in this study by demonstrating their ability to use a Turbuhaler® and a Spiromax® device. There was no significant difference between the proportion of participants who demonstrated device mastery with the Turbuhaler® compared with the Spiromax® at level 1, (no instruction), (119/228 (52%) versus 131/228 (57%), respectively, n = 228, p = 0.323 (McNemar's test of paired data). All but one participant had demonstrated correct inhaler technique for both devices by level 3(instructional video). There was a significant difference between the proportion of participants who demonstrated maintenance of device mastery with the Turbuhaler® compared with the Spiromax® at visit 2, level 1 (127/177 (72%) versus 151/177 (85%) respectively, p = 0.003; McNemar's test of paired data). All but two participants achieved device mastery by level 3, visit 2. More participants reported previous training with the Turbuhaler® than with Spiromax®.DiscussionThis study demonstrates that GPs are able to equally demonstrate correct use of the Turbuhaler® and Spiromax® devices, even though most had not received training on a Spiromax® device prior to this study. The significance of being able to demonstrate correct technique on these two devices equally has ramifications on practice and supported generic substitution of inhaler devices at the point of prescribing, as the most impactful measure a GP can take to ensure effective use of inhaled medicine is the correct demonstration of inhaler technique.

Project description:BackgroundMore people are living longer lives leading to a growth in the population of older adults, many of whom have comorbidities and low levels of physical function. Physical activity in later life can prevent or delay age-related disability. Identifying a cost-effective means of increasing physical activity in older adults therefore remains an important public health priority.Physical Activity Facilitation (PAF) is an intervention shown to increase physical activity in adults with depression. The PAF model was modified for a population of older adults at risk of disability. This study aimed to assess the feasibility of undertaking a definitive RCT of the PAF intervention in the target population.MethodsA pilot randomised controlled trial (RCT) was delivered through primary care. Patients at risk of disability and who were not meeting recommended levels of physical activity were recruited through postal invitation and direct approach in the practice waiting room. Those meeting eligibility criteria were enrolled and randomised at a 2:1 ratio to the PAF intervention and control. Behaviour change techniques were used by facilitators with participants over the telephone and face-to-face for 6 months. Outcome measures including physical function, physical activity, depression, social support, and quality of life were collected at baseline and at 6 months.ResultsA high proportion of patients responded to the initial invitation (68%), yet many were ineligible due to high levels of self-reported physical activity and baseline physical function. Fifty-one participants were recruited to the trial, with an average age of 74 years (range 65-89), and there were high rates of adherence and retention to the study (94% follow-up at 6 months). The majority of outcome data collected from participants was complete; however, the validated scale used to measure self-reported physical activity was associated with high levels of missing data.ConclusionsThe findings of this pilot RCT suggest that it is feasible to deliver a definitive RCT of the PAF intervention in this population. Further work is required to improve the efficiency of recruitment and to minimise missing data from self-reported physical activity measures.Trial registrationCurrent controlled trials ISRCTN80470273.

Project description:IntroductionMedication adherence and inhaler technique in patients with asthma remain suboptimal. A digital, smart spacer may support personalised adherence and inhaler technique education. The aim of this study is to assess the feasibility of undertaking a definitive randomised controlled trial of personalised, smart spacer data-driven education and explore clinical benefits.Methods and analysisWe present the design of the multicentre, randomised controlled OUtcomes following Tailored Education and Retraining: Studying Performance and AdherenCE feasibility trial of 2 months. Patients will be recruited from four Dutch general practices. At t=-1, patients with asthma ≥18 years using inhaled corticosteroids±long-acting beta-agonists±short-acting beta-agonists administered with a pressurised-metered-dose-inhaler and spacer (n=40) will use a smart spacer for 1 month. The rechargeable CE-marked smart spacer (Aerochamber Plus with Flow Vu) includes a sensor that monitors adherence and inhalation technique to prescribed dosing regimen of both maintenance and reliever inhalers. After 1 month (t=0), patients are 1:1 randomised into two groups: control group (usual care) versus intervention group (personalised education). At t=-1, t=0 and t=1 month, the Asthma Control Questionnaire (ACQ), Work Productivity and Activity Impairment (WPAI) questionnaire and Test of Adherence to Inhalers (TAI) are administered and fractional exhaled nitric oxide (FeNO) is assessed. At t=0 and t=1, spirometry is performed. At t=1, usability and satisfaction will be analysed using the System Usability Scale and interviews with patients and healthcare providers. Primary outcome is the overall feasibility of a definitive trial assessed by patient recruitment speed, participation and drop-out rate. Secondary outcomes are patient and healthcare provider satisfaction and exploratory clinical outcomes are adherence, inhaler technique, TAI score, FeNO, lung function, ACQ and WPAI.Ethics and disseminationEthical approval was obtained from the RTPO in Leeuwarden, Netherlands (number: NL78361.099.21). Patients will provide written informed consent. Study findings will be disseminated through conferences and peer-reviewed scientific and professional journals.Trial registration numberNL9637.

Project description:INTRODUCTION:In clinical practice, it is difficult to distinguish between patients with refractory asthma from those with poorly controlled asthma, where symptoms persist due to poor adherence, inadequate inhaler technique or comorbid diseases. We designed an audio recording device which, when attached to an inhaler, objectively identifies the time and technique of inhaler use, thereby assessing both aspects of adherence. This study will test the hypothesis that feedback on these two aspects of adherence when passed on to patients improves adherence and helps clinicians distinguish refractory from difficult-to-control asthma. METHODS:This is a single, blind, prospective, randomised, clinical trial performed at 5 research centres. Patients with partially controlled or uncontrolled severe asthma who have also had at least one severe asthma exacerbation in the prior year are eligible to participate. The effect of two types of nurse-delivered education interventions to promote adherence and inhaler technique will be assessed. The active group will receive feedback on their inhaler technique and adherence from the new device over a 3-month period. The control group will also receive training in inhaler technique and strategies to promote adherence, but no feedback from the device. The primary outcome is the difference in actual adherence, a measure that incorporates time and technique of inhaler use between groups at the end of the third month. Secondary outcomes include the number of patients who remain refractory despite good adherence, and differences in the components of adherence after the intervention. Data will be analysed on an intention-to-treat and a per-protocol basis. The sample size is 220 subjects (110 in each group), and loss to follow-up is estimated at 10% which will allow results to show a 10% difference (0.8 power) in adherence between group means with a type I error probability of 0.05.
