The clinical effectiveness and cost-effectiveness of inhaler devices used in the routine management of chronic asthma in older children: a systematic review and economic evaluation

Background: This review examines the clinical effectiveness and cost-effectiveness of hand-held inhalers to deliver medication for the routine management of chronic asthma in children aged between 5 and 15 years. Asthma is a common disease of the airways, with a prevalence of treated asthma in 5–15-year-olds of around 12% and an actual prevalence in the community as high as 23%. Treatment for the condition is predominantly by inhalation of medication. There are three main types of inhaler device, pressurised metered dose, breath actuated, and dry powder, with the option of the attachment of a spacer to the first two devices under some prescribed circumstances. Two recent reviews have examined the clinical and cost-effectiveness evidence on inhaler devices, but one was for children aged under 5 years and the comparison in the second was made between pressurised metered dose inhalers and other types only. Objectives: This review examines the clinical effectiveness and cost-effectiveness of manual pressurised metered dose inhalers, breath-actuated metered dose inhalers, and breath-actuated dry powder inhalers, with and without spacers as appropriate, to deliver medication for the routine management of chronic asthma in children aged between 5 and 15 years. Methods: Two previous HTA reviews have compared the effectiveness of inhaler devices, one focusing on asthma in children aged under 5 years and the other on asthma and chronic obstructive airways disease in all age groups. For the current review, a literature search was carried out to identify all evidence relating to the use of inhalers in older children with chronic asthma. A search of in-vitro studies undertaken for one of the previous reviews was also updated. The data sources used were: 15 electronic bibliographic databases; the reference lists of one of the previous HTA reports and other relevant articles; health services research-related internet resources; and all sponsor submissions. Studies were selected according to strict inclusion and exclusion criteria, and relevant information concerning effectiveness and patient compliance and preference was extracted directly on to an extraction/evidence table. Quality assurance was monitored. Economic evaluation was undertaken by reviewing existing cost-effective evidence. Further economic modelling was carried out, and tables constructed to determine device cost-minimisation and incremental quality-adjusted life-year (QALY) thresholds between devices. Results: Number and quality of studies, and direction of evidence: Fourteen randomised controlled studies were identified relating to the clinical effectiveness of inhaler devices for delivering β2-agonists. A further five were on devices delivering corticosteroids and one concerned the delivery of cromoglicate. Overall, there were no differences in clinical efficacy between inhaler devices, but a pressurised metered dose inhaler with a spacer would appear to be more effective than one without. These findings endorse those of a previous HTA review but extend them to other inhaler devices. Seven randomised controlled trials examined the impact on clinical effectiveness of using a nonchlorofluorocarbon (CFC) propellant in place of a CFC propellant in metered dose inhalers, both pressurised and breath activated, although only one study considered the latter type. No differences were found between inhalers containing either propellant. A further 30 studies of varying quality, from 12 randomised controlled trials to non-controlled studies, were identified that concerned the impact of use by, and preference for, inhaler type, and treatment adherence in children. Differences between the studies, and limitations in comparative data between various inhaler device types, make it difficult to draw any firm conclusions from this evidence. Summary of benefits: No obvious benefits for one inhaler device type over another for use in children aged 5–15 years were identified. Costs and cost per quality-adjusted life-year: Two approaches have been taken: cost-minimisation and QALY threshold. In the QALY threshold approach, additional QALYs that each device must produce compared with a cheaper device to achieve an acceptable cost per QALY were calculated. Using the cheapest and most expensive devices for delivering 200 μg of beclometasone per day, assuming no cost offset for any device, and a threshold of £5000, the largest QALY needed was 0.00807. With such a small QALY increase, no intervention can be categorically rejected as not cost-effective. Conclusions: Generalisability of findings: On the available evidence there are no obvious benefits for one inhaler device over another when used by children aged 5–15 years with chronic asthma. However, the evidence, in the majority of cases, was compiled on children with mild to moderate asthma and restricted to a limited number of drugs. Therefore the findings may not be generalisable to those at the more severe end of the spectrum of the disease or to inhaler devices delivering some of the drugs used in the management of asthma. Need for further research: Many of the previous studies are likely to have been underpowered. Further clinical trials with a robust methodology, sufficient power and qualitative components are needed to demonstrate any differences in clinical resource use and patients’ asthma symptoms. Further studies should also include the behavioural aspects of patients towards their medication and its delivery mechanisms. It is acknowledged that sufficient power may prove impractical owing to the large numbers of patients required

Technical and Behavioral Interventions for Medication Adherence through Mobile Health

In this research, we present a novel intervention, Carrot and Stick, to improve the outcome of one of the self-management tasks, medication adherence (MA), among patients with chronic disease(s). Our design incorporates the growing importance of mobile health (m-health) in Health Information Technology (HIT) with the users’ dependency on mobile phones to facilitate valuable behavioral changes. Drawing on Social Cognitive Theory, Social Exchange Theory, Goal-setting Theory, and people’s dependence on smartphones, we develop the functionalities in our intervention, including positive and negative reinforcement, goal-setting, and social connections. The iterative process of our development follows the Design Science Approach. In the evaluation and validation of our intervention, we not only examine the intervention’s impacts on patients through analytical models and simulation but also demonstrate the possible active support of the intervention from healthcare providers based on the current pay-for-performance (P4P) scheme. Our results suggest that (1) with the help of electronic medication container, appropriate reminder design can reduce the patients’ chances of forgetting doses, overdosing, and intaking doses at the wrong time, (2) positive reinforcement can help increase the probability of the patient achieving expected MA, while negative reinforcement has a further impact that is added to the increment, (3) our intervention can assist the patient in saving more than $600 per year, and (4) under the current P4P scheme, physicians with the exceptional performance or with bad performance are likely to invest in the intervention to change their patients’ behaviors, while physicians with good performance are less likely to participate. Our research is the first to utilize negative reinforcement in intervention design to enhance MA; it is also the first to provide corresponding interventional solutions that are customized according to elements derived from theories. Besides, the focus and understanding of healthcare providers’ involvement in the incentive program can facilitate the adoption, prescription, and implementation of the proposed intervention

The nurse of the Mediterranean

During the First World War Malta did not take an active part in the fighting. Britain was joined in an ‘entente’ a friendship agreement with France since 1904 and later with Russia in 1907. On the other hand Germany was allied to the Austrian- Hungerian Empire, hence when the Great War started in July 1914 there were France, Britain and Russia on one side and Germany and Austria-Hungary on the other. The British fleet “ruled the waves”, hence with France and Britain as allies, to be joined later by Italy, the Mediterranean was more or less an allied lake, with Malta in the centre.peer-reviewe

Comprehensive, Evidence-Based, Consensus Guidelines for Prescription of Opioids for Chronic Non-Cancer Pain from the American Society of Interventional Pain Physicians (ASIPP).

BACKGROUND: Opioid prescribing in the United States is decreasing, however, the opioid epidemic is continuing at an uncontrollable rate. Available data show a significant number of opioid deaths, primarily associated with illicit fentanyl use. It is interesting to also note that the data show no clear correlation between opioid prescribing (either number of prescriptions or morphine milligram equivalent [MME] per capita), opioid hospitalizations, and deaths. Furthermore, the data suggest that the 2016 guidelines from the Centers for Disease Control and Prevention (CDC) have resulted in notable problems including increased hospitalizations and mental health disorders due to the lack of appropriate opioid prescribing as well as inaptly rapid tapering or weaning processes. Consequently, when examined in light of other policies and complications caused by COVID-19, a fourth wave of the opioid epidemic has been emerging. OBJECTIVES: In light of this, we herein seek to provide guidance for the prescription of opioids for the management of chronic non-cancer pain. These clinical practice guidelines are based upon a systematic review of both clinical and epidemiological evidence and have been developed by a panel of multidisciplinary experts assessing the quality of the evidence and the strength of recommendations and offer a clear explanation of logical relationships between various care options and health outcomes. METHODS: The methods utilized included the development of objectives and key questions for the various facets of opioid prescribing practice. Also utilized were employment of trustworthy standards, and appropriate disclosures of conflicts of interest(s). The literature pertaining to opioid use, abuse, effectiveness, and adverse consequences was reviewed. The recommendations were developed after the appropriate review of text and questions by a panel of multidisciplinary subject matter experts, who tabulated comments, incorporated changes, and developed focal responses to questions posed. The multidisciplinary panel finalized 20 guideline recommendations for prescription of opioids for chronic non-cancer pain. Summary of the results showed over 90% agreement for the final 20 recommendations with strong consensus. The consensus guidelines included 4 sections specific to opioid therapy with 1) ten recommendations particular to initial steps of opioid therapy; 2) five recommendations for assessment of effectiveness of opioid therapy; 3) three recommendations regarding monitoring adherence and side effects; and 4) two general, final phase recommendations. LIMITATIONS: There is a continued paucity of literature of long-term opioid therapy addressing chronic non-cancer pain. Further, significant biases exist in the preparation of guidelines, which has led to highly variable rules and regulations across various states. CONCLUSION: These guidelines were developed based upon a comprehensive review of the literature, consensus among expert panelists, and in alignment with patient preferences, and shared decision-making so as to improve the long-term pain relief and function in patients with chronic non-cancer pain. Consequently, it was concluded - and herein recommended - that chronic opioid therapy should be provided in low doses with appropriate adherence monitoring and understanding of adverse events only to those patients with a proven medical necessity, and who exhibit stable improvement in both pain relief and activities of daily function, either independently or in conjunction with other modalities of treatments

Pharmacotherapy review: a proposal to improve medication adherence among hypertensive patients

A revisão da farmacoterapia é uma avaliação estruturada dos medicamentos com o objetivo de proporcionar aos pacientes o alcance dos objetivos terapêuticos por meio da forma adequada de administração dos medicamentos. O objetivo foi analisar a influência da revisão da farmacoterapia, por meio do aprazamento dos medicamentos, na adesão à medicação e no controle da hipertensão arterial sistêmica. Trata-se de um estudo de intervenção não controlado desenvolvido em três momentos distintos. No primeiro, realizou-se a coleta de dados sobre o perfil dos pacientes e de suas medicações e a avaliação da adesão; no segundo momento, realizou-se a entrega do relatório da revisão aos pacientes e na terceira etapa avaliou-se o resultado da adesão e pressão arterial. A influência da revisão foi medida por meio de testes estatísticos (pharmacotherapy review is a structured assessment of medicines, which aims to obtain a partnership with patients to achieve drug treatment goals and agreement about drug dosage, as well as when and how the drugs should be administered. The objective was to analyze the influence of pharmacotherapy review, by scheduling drug administration to improve medication adherence among antihypertensive patients. This study was an uncontrolled intervention developed in three distinct stages. The first stage included data collection on the profile of patients and their medications, and a preliminary assessment of medication adherence. In the second stage, the review report was delivered to patients. In the third stage, the results of blood pressure and medication adherence were assessed. The influence of the revision was measured through statistical tests (

How do the attitudes and beliefs of healthcare professionals and older people impact on the appropriate use of multi-compartment compliance aids by older people living at home

Compliance with medication regimes is a widely researched topic within the field of healthcare. Older people are considered to be a greater risk of non-compliance due to multiple morbidities. Multi-compartment compliance aids are frequently issued to older people in an attempt to improve their medicines management. This thesis aims to determine whether the attitudes and beliefs of both the older people who use MCAs and the healthcare professionals who request their use, influence the use of such devices by older people living in the community. A preliminary study which investigated the use of MCAs in primary care is described. The findings suggested that over 100,00 people in the UK may be issued with a MCA despite little evidence for their efficacy. The literature review undertaken for this thesis concludes that very few studies have been undertaken in this area and those which have are mainly of poor quality. The results from these studies failed to conclusively support the use of these devices and further rigorous conducted studies are needed. The main study comprises qualitative, in-depth semi-structured interviews with older people, who are using a MCA and healthcare professionals. The interviews were analysed using a grounded theory approach. The study revealed that older people find MCAs easy to use and convenient although a minority of the participants did experience difficulties using the device. Maintaining independence and remaining in control was important for all the older people and this influenced their attitudes towards using their MCA. The healthcare professionals concurred with the observation that MCAs were convenient to use and despite a minority stating that MCAs assisted older people to remember to take their medication, the majority acknowledged that this was not the case. The healthcare professionals agreed that the decision to issue a MCA could be seen as paternalistic however there remained a belief that the issue of a MCA would assist the older person take their medication correctly. The thesis concludes by providing details of a proposed method for undertaking a holistic, patient-centred, multi-disciplinary assessment of older people's medicines management abilities
