The paper describing the Active Life with Asthma (ALMA) questionnaire by Kiotseridis et al.1 in this issue of the Primary Care Respiratory Journal raises as many questions as it answers. The technical issue addressed in the paper about the validity of a subset of questions as an assessment of asthma control is arguably the simplest of the questions to answer. Derived appropriately from qualitative investigation, the 14 questions designed to measure control compared well with the ‘gold standard’ Asthma Control Questionnaire (ACQ).2 The more interesting questions, however, have yet to be addressed:

a) How do questionnaires fit into the well defined structure of a primary care consultation?

Experience in UK primary care where use of the Patient Health Questionnaire-9 (PHQ-9) was introduced as a measure of the severity of depression in the Quality and Outcomes Framework (QOF)3 in 2006 is not entirely encouraging. Although patients were relatively positive and considered that completing questionnaires made them feel as if they were being taken more seriously,4 general practitioners (GPs) thought that asking patients to complete a questionnaire was intrusive, interrupted the flow of the consultation, and added little to their clinical judgement.5 However, the International Primary Care Respiratory Group (IPCRG) in their recent prioritisation of research needs, identified the development of questionnaires (or just ‘questions’) as an important means of diagnosing and assessing respiratory conditions in the comparatively low-technology context of primary care.6 Objective assessment of control is a core component of asthma reviews which underpins management decisions.7 The ALMA tool offers some validated morbidity questions, though how the questions can best be incorporated into an asthma consultation may be a practical concern for some clinicians.

b) Will questionnaires be completed ‘properly’ in clinical practice?

The science underpinning the development of Patient Reported Outcome Measures (PROMs) emphasises the importance not only of the precise wording of questions but also of context and mode of delivery in ensuring that the instrument measures consistently what it is intended to measure.8 Instruments such as the ACQ are validated by self-selected volunteer patients completing questionnaires under the supervision of trained researchers, and new modes of administration are carefully assessed to ensure that they do not compromise response rates or validity.9,10 Developers of questionnaires have long expressed the hope that their instrument will have clinical applicability,11 but in clinical practice such careful standardisation is unlikely, with clinicians adopting a range of practical strategies to overcome the challenges of time, language, poor literacy and perceived disruption of consultation. Experience with the PHQ-9 in the context of the QOF identified seven such strategies,12 (including incorporating paraphrased questions into the conversation and calculating a score after the consultation), thus completely negating validation. Although the questions used in the validation exercise reported by Kiotseridis et al. were obtained by self-completion of a (5-minute) paper questionnaire, the ‘real-life’ ALMA database is a (presumably clinician-completed) web-based application which immediately changes the dynamics of completion.

c) What impact does a template have on an asthma review?

The ALMA database, however, is more than another PROM assessing asthma control: it is a tool intended to structure asthma reviews. Structured asthma care, including assessment of control, has been shown to improve patient outcomes — for example, in the Australian 3+ visit plan.13 Templates may be welcomed as a means of improving clinicians' adherence to protocols,14 though they have led to concerns about imposing a routine that potentially excludes the patient's agenda.15 Completing checklists may encourage the recording of negative findings that have not been explicitly elicited.16 The authors should consider recording asthma reviews or undertaking qualitative research to explore how the ALMA tool is applied, the impact it has on the process of the consultation, and crucially, whether identification of poor control triggers appropriate stepping up of treatment and improved outcomes for patients.

d) How might healthcare systems benefit?

There is a final question for the ALMA tool: can the questionnaire raise standards of care across a healthcare community? Routine use and the development of a database offers the opportunity to observe standards of practice and then to benchmark good practice as a first step to driving up quality of care. Although morbidity scores have been widely used to assess asthma control as part of initiatives to improve care across healthcare communities — for example in Finland17 and the USA18 — the data are generally collected by self-completed questionnaire as part of the evaluation of an initiative and thus do not reflect the real-life assessment of control using routinely collected data. The IPCRG Helping Asthma in Real Patients (HARP) study piloted in Ireland19 and now rolled out to the UK, Germany, France, Italy, Spain, Sweden, Norway and Australia uses some routinely collected data extracted from practice computer systems, but overcomes the lack of coded symptoms by sending questionnaires to people with asthma to assess morbidity.

By establishing a database of asthma assessments undertaken within the local healthcare community, the ALMA project has an important opportunity to monitor patient-related outcomes and the impact of initiatives on standards of care. An explicit focus on quality improvement is a key aim of the UK QOF.20 When 20% of practice income is attached to pay for performance indicators, motivation to achieve maximum points is high (UK practices achieved 98.7% of available asthma QOF points in 2010/1121). It will be interesting to compare the results of the voluntary ALMA scheme with the standards achieved in the financially-rewarded QOF.

A question of quality

The initiative described by Kiotseridis et al. provides an answer to one question: asthma control recorded by the ALMA questionnaire compares well to the gold standard ACQ. Time and further research will tell whether by structuring assessment of control it is possible to improve the quality of care provided to individual patients — and also, by routinely monitoring structured asthma reviews, raise the quality of asthma care within a healthcare community. The question is one of quality.
