Overview

The role of the pharmacist in the asthma management is well established. However, there is still a considerable number of patients with suboptimal asthma control affecting patients’ quality of life and resulting in poor outcomes, morbidity and mortality. The aim was to identify patients’ factors, explore the hospital pharmacist’s role in the asthma management and identify any areas for improvement in Great Britain. Qualitative data collection was selected. Patient’s case studies and semi-structured open interviews with the hospital multi-disciplinary team (MDT) were applied. Data were analysed and grouped into themes. Patient’s case studies showed a variety in the patients’ understanding of the pharmacist’s role in their asthma management and similarly of the pharmacy services available to them. From the MDT interviews it emerged that communication across the secondary/primary care is lacking at times, and as a result new communication systems are being implemented. More research is needed into the asthma-patients’ needs and expectations of pharmacy service. The hospital pharmacists are well placed to recognise asthma patients requiring pharmaceutical interventions and to provide medicines optimisation, across the primary/ secondary care settings. It was observed that the level of patient’s involvement in their asthma was dependent on their interest in utilising asthma information and pharmacy services.

Introduction

Even though asthma prevalence is thought to have plateau since the late 1990s, it still has a high prevalence of morbidity and mortality1, 2) and a poor level of control as recent European studies demonstrated: INSPIRE3), REALISE4), AIRE5) and Demoly et al.6). It is estimated that asthma affects 334 million people worldwide with 30 million people in Europe while suboptimal asthma control leads to an increased risk of exacerbations, reduced productivity, reduced quality of life and increased healthcare costs7).

Despite many advances in asthma treatments and care a considerable number of people treated for asthma will die from asthma every year in Europe (1.21 per 100.000) and worldwide (3.96 per 100.000) putting a substantial economic burden of asthma on the society with 72.2billion € spent per annum and 14.4 billion € cost for loss of productivity due to work absence, early retirement and premature mortality2, 8). Most asthma associated deaths occur outside of hospital while most people die from asthma due to delay in taking action when the condition is getting worse due to leaving it too long or due to failure to recognise the worsening signs and symptoms of an acute exacerbation1, 9, 10).

From the pharmacological point of view, the main asthma symptoms are inflammation and bronchoconstriction and therefore use of medications is focused on reducing inflammation and increasing bronchodilation, together with adjuvant medications alleviating asthma symptoms10–12). The aims of asthma treatment are focused on minimising symptoms, minimising need for medication and adverse effects of treatment, maximising lung functions, preventing exacerbations, facilitating self- management, individualised treatment, medication adherence, healthy and active lifestyle, providing supporting information and follow- ups and monitoring and assessing signs of deterioration9, 13).

Apart from the pharmacological treatments14–18), there are several non-pharmacological management approaches targeting asthma triggers and co-morbidities and which when used in conjunction with the pharmacological treatments may facilitate better asthma management. In order to involve patients in their asthma self-care, patient education is the most important requirement in sustaining effective asthma management. Patient education needs to be aimed at enhancing patient’s understating of their asthma and how their symptoms can be best controlled through their own direct self-involvement. The multidisciplinary team (MDT) generally looks after the asthma patient in the hospital setting and to some degree across the two settings (primary and secondary care).

However, every healthcare professional including the pharmacist needs to remember that education is an ongoing process and that regular follow-up visits are necessary in order to maintain continuity of the patient’s involvement and understanding. Interactive interventions and sharing advice in person are more effective than giving out written information on its own and when combined together, the two methods have the highest impact.

A systematic approach to the evaluation of patients with suspected asthma or patients known to have asthma is essential19). Each asthma patient should be offered self-management individual approach11, 20), have their asthma reviewed with a healthcare professional including the pharmacist’s input. Each asthma patient should have their PAAP (personalised asthma action plan) outlined.

In terms of quantitative studies on effectiveness and cost-effectiveness of asthma care there is a substantial evidence21) proving a global socioeconomic burden of asthma and the degree of disease control on the society. However, quantitative studies often lack to establish how the level of pharmaceutical intervention adherence is linked with patients’ individual outcomes and expectations and with the cost-effectiveness in long term.

The aim

Taking into consideration the above factors, the aim of this qualitative enquiry was to identify patients’ factors, explore hospital pharmacists’ role in the asthma management and identify any areas for improvement.

Experimental part

The method for collecting the qualitative data was designed in a form of a case study template and a set of open questions to guide the interviews22, 23). Three core activities as per ethical requirements were utilised, which were case studies, open interviews with the patients and the MDT members involved in the secondary asthma care and finally analysis of the hospital pharmacist’s role in the asthma management. Five patients were chosen randomly with the patients’ consent while making sure that the pharmacist’s interventions were focused around asthma care. As for the members of the MDT (5 persons) – ward pharmacists, respiratory physicians, specialists’ asthma nurses were all included in the interviews. The recruitment into the case studies and the interviewing took place in the NHS (National Health Service) hospital (Great Britain) between January and May 2016.

Results

Practice evaluation – case studies

As demonstrated in the five case studies the hospital pharmacist was collectively involved in the following asthma management interventions:

  • medication history taking
  • medicines reconciliation
  • counselling
  • asthma information provision to the individual patients
  • reassurance and explanation of acute treatments and of any changes
  • checking correct inhaler technique
  • ordering supplies of the patients’ medications on time
  • signposting to community pharmacy services
  • following-up the medications errors
  • communicating with the hospital MDT and the community team
  • explanation of a correct use and an over-use of relievers/preventers
  • recognising an inappropriate inhaler device
  • encouraging and reassuring the patients

Data collected during the case studies confirmed that the hospital pharmacists are actively involved in various aspects of the pharmaceutical care provided for the asthma patients who are admitted into the secondary care with uncontrolled asthma. Medications counselling, information provision, treatment discussions and a general reassurance of the hospital patients were the core activities that the hospital pharmacists engage during the ward visits. From the case studies, it can be demonstrated that the hospital pharmacists are capable of identifying patients with poorly controlled asthma and providing them with a suitable and timely interventions. To support the above findings as observed in practice, various studies advocate the importance of the pharmacists’ input in the asthma management and delivering asthma interventions11, 24–26).

Practice evaluation – MDT

Based on the MDT members’ individual views five core themes were identified, which are pharmaceutical care (as a central theme) interconnected to clinical governance, patients’ factors, communication and barriers.

From the interviews, the hospital pharmacists had the most comprehensive knowledge of currently available systems allowing them to communicate medications’ issues to the general practitioners and community pharmacists. However, locally a system that would allow a direct communication with a community pharmacist in terms of pharmacy referrals was lacking. Similarly, the hospital doctors who often utilize pharmacy services appeared to have a good understanding of the pharmacists’ role and believed that patients’ medications are a shared responsibility. The hospital doctors believed that the pharmacists are best placed to communicate medications issues directly to the primary care. This was also expressed by the asthma nurses, who stated that it was the pharmacists’ and the hospital doctors’ responsibility to communicate medications issues with the primary care. On the other hand, the asthma nurses would like to see more input into empowering patients in taking more responsibility for their own medications rather than relying solely on the healthcare professionals. Overall, clinical governance underpinned all pharmaceutical care27) and from the themes identified from the interviews it is apparent that it was at the forefront of ensuring a provision of a good quality pharmaceutical care.

Practice evaluation – patients’ perspective

As for the resources available for asthma patients, from the patient’s interviews and from the visit to the asthma clinical the following sources of information were identified:

Each patient had their PAAP in place, which was in accordance with the current recommendations and guidelines1, 11, 13, 20) and which included:

  • personalised information
  • general information for asthma management
  • steps to take in everyday asthma care
  • steps to take if symptoms start and the patient feels worse
  • steps to take in an asthma attack
  • what medications to take and how
  • list the patient’s specific triggers that needs to be avoided
  • state the next review date
  • physician and asthma nurse contact details
  • help others to understand what to do in case of an asthma attack

When discussing resources available for the patients in practice, the patients who were familiar with the electronic resources preferred the British Lung Foundation (BLF)28) and the Asthma UK9) as the most resourceful web sites in the UK. Both web sites were also used in the local NHS Trust as a valuable source of asthma information. Some patients in the case studies expressed that they may find it helpful to share their experience and feelings with other patients in the similar situation and they expressed an interest in joining the Asthma UK9) or the BLF28) website, where the patients can ‘sign-in’ and receive regular up-dates on asthma, or join the asthma community and get in touch with others via the website asthma forum. Some patients may not want to be involved in their asthma care decision making and these patients’ passive approach needs to be respected by the pharmacists and the MDT whilst every effort should be made to facilitate adherence with the asthma treatment in order to minimise the risk of asthma exacerbations. As observed in practice, one of the patients expressed unwillingness to be involved in any extra activities, extra visits or extra counselling and despite being overall uninterested in taking an active part in her asthma, her overall compliance was satisfactory.

Discussion

When critically analysing the data set and practice observations as a whole, it was apparent that clinical evidence from practice was complacent with the current recommendations in the clinical guidelines as shown below:

  • Standards of conduct, ethics and performance29)
  • NICE (National Institute for Health and Care Excellence) Medicines Optimisation30)
  • NICE Patient experience31)
  • Confidentiality Policy NHS England32)
  • Equity and excellence: Liberating the NHS33)
  • The Good Medical Practice34)
  • The NHS Code of Practice35)
  • Asthma quality standards

Additionally, studies that tested asthma assessment tools and their validity20) 36–38), jointly advocate their invaluable place in recognising patients’ level of asthma control and in identifying patients at risk. However, even though current asthma guidelines and asthma assessment tools are well established, are in place and are followed recent studies into asthma morbidity and mortality1, 2) are proving that asthma control remains suboptimal.

This is also clear from the findings of the five case studies, where some patients’ understanding of some aspects of their asthma management was lacking. Patients with only a minimal contact with pharmacy were in some degree unfamiliar with pharmacy services and what they may be eligible for, which may indicate the reasons why they did not seek advice of the community or the general practice pharmacist at the time of symptoms deterioration. Patients’ lack of awareness of pharmaceutical services and their perceptions of their asthma could be improved through pharmacists’ pro-active approach, facilitating signposting, encouraging patients’ visits and involvement with pharmacy services and enhancing self-efficacy and asthma control39). Additionally, with today’s network advances some patients may find it helpful to browse information resources independently, whilst other patients may find the opposite is true. There are also differences in patients’ willingness to be involved in their care, which clearly indicates the need to tailor asthma management together with the individual patient according to their individual needs and expectations. This is also supported in a recent meta-analysis40) which strongly confirmed that supported self-management of asthma can improve asthma control, asthma outcomes and reduce hospital admissions.

Therefore, healthcare professionals involved in asthma care provision including the pharmacists should join their efforts and commit into exploring where the barriers are and how best to address them in order to reduce unnecessary asthma deaths and improve patients’ outcomes and quality of life. Some recent studies41, 42) explored barriers to the implementation of asthma guidelines from the patients’ perspective and suggested the focus should be on holistic therapy and shared, individual and personalised asthma care counselling in long-term asthma management.

In terms of recommendations for future, development of asthma guidelines should involve patients’ more readily and include patients’ perspectives and expectations. As for the pharmacists’ role in asthma management, they should be more pro-active in seeking to engage in shared decision making process with the individual asthma patients regarding their targeted interventions and tailored asthma outcomes.

Study carried out in the Czech Republic43) identified a need to an individualised asthma patients’ approach and the role of the pharmacists as invaluable, however barriers remain to enhance currently provided pharmacy service and the recommendation would be to pursue and facilitate involvement of asthma patients as much as feasible.
