Use of the pictorial Sleepiness and Sleep Apnoea Scale in Chinese patients with suspected obstructive sleep apnoea syndrome.

BACKGROUND: Sleep related breathing disorders represent a significant health burden. Being able to stratify patients according to their need for differing types of investigation and predicting the likelihood of obstructive sleep apnoea syndrome (OSAS) is helpful. This study attempts to assess the value of a pictorial Sleepiness and Sleep Apnoea Scale (pSSAS) in this process. METHODS: A total of 126 sequential patients attending a sleep service with suspected OSAS completed the pSSAS, the Epworth Sleepiness Score (ESS), and the Berlin Questionnaire (BQ) prior to full polysomnography. RESULTS: With Apnoea-hypopnea index (AHI) >15 as the positive diagnostic criterion, the area under the receiver operating characteristic curve (AUC) of the BQ was the highest (0.683), followed by pSSAS and ESS (AUC 0.648 and 0.516, respectively). With AHI >30 as the positive diagnostic criterion, the AUC of pSSAS was the highest (0.696), followed by BQ and ESS (AUC 0.653 and 0.510, respectively). With MiniSO2 <80% as the positive diagnostic criterion, the AUC of pSSAS was the highest (0.736), followed by BQ and ESS (AUC 0.634 and 0.516, respectively). CONCLUSIONS: This study shows that the pSSAS which was first tested in a European population performs equally well amongst a Chinese population. The pSSAS performed in a similar fashion to the BQ in predicting those likely to have OSAS and was superior at predicting those who have severe OSAS. Because it is a pictorial questionnaire, it has advantages for those who may have reduced health literacy, a problem which is under-recognized in most healthcare systems.

How is the education component of pulmonary rehabilitation delivered in practice--Is it patient-centred?

OBJECTIVES: Pulmonary rehabilitation (PR) involves a significant component of education, but little has been published on what educational content is covered or how it is delivered. This survey study set out to investigate how PR education is delivered in practice. METHODS: A survey was designed to investigate the current educational delivery and which topics respondents reported should be included in a PR programme. The survey was sent to 11 Scottish PR Action group regional leads. RESULTS: Nine completed the questionnaire (81.8%). Education was reported to be predominately group-based and face-to-face (n = 9, 100%) consisting of between 6 and 12 sessions. Most educational topics lasted 15 min or less, some topic areas were not consistently covered. The educational content was variable and not personalised to individual needs. Three health areas undertook informal literacy assessment at baseline assessment and when tailoring COPD plans. Often attendance at educational sessions was not needed to 'complete' PR. CONCLUSIONS: Content and delivery of educational topics were varied, and no consistent outcome measure to assess the effectiveness of education was used. PRACTICE IMPLICATIONS: Education needs to be delivered in a patient-centred way tailoring for literacy skills using a range of different teaching approaches and aids.

Reflections on integrated care from those working in and leading integrated respiratory teams.

The concept of integrated care has been advocated for many years to address some of the challenges faced by the NHS. This report examines the experiences of respiratory healthcare specialists working in an integrated role. Twelve qualitative telephone interviews were undertaken with a range of integrated respiratory specialists and their teams working in both hospitals and the community. A descriptive and thematic approach to data analysis was adopted. Participants were very enthusiastic about their roles and saw themselves as ambassadors for this new way of working. Several key themes were identified from the analysis which participants identified as barriers or enablers to the successful undertaking of an integrated respiratory specialist role. These included the participants' previous work experience and background, the range of multi-disciplinary expertise within or needed for the team, the structure of the team leadership and the measurement of outcomes to evaluate the team. Participants identified the need for clear job descriptions and roles, shared training and standards and appropriate outcome evaluation. More research is needed to understand how these new ways of working are developing and how they can be evaluated.

A pictorial Sleepiness and Sleep Apnoea Scale to recognize individuals with high risk for obstructive sleep apnea syndrome.

PURPOSE: The aim of this study was to evaluate the validity of a new pictorial form of a screening test for obstructive sleep apnea syndrome (OSAS) - the pictorial Sleepiness and Sleep Apnoea Scale (pSSAS). Validation was performed in a sample of patients admitted to sleep clinics in the UK and Switzerland. PATIENTS AND METHODS: All study participants were investigated with objective sleep tests such as full-night-attended polysomnography or polygraphy. The pSSAS was validated by taking into account the individual result of the sleep study, sleep-related questionnaires and objective parameters such as body mass index (BMI) or neck circumference. Different scoring schemes of the pSSAS were evaluated, and an internal validation was undertaken. RESULTS: The full data set consisted of 431 individuals (234 patients from the UK, 197 patients from Switzerland). The pSSAS showed good predictive performance for OSAS with an area under the curve between 0.77 and 0.81 depending on which scoring scheme was used. The subscores of the pSSAS had a moderate-to-strong correlation with widely used screening questionnaires for OSAS or excessive daytime sleepiness as well as with BMI and neck circumference. CONCLUSION: The pSSAS can be used to select patients with a high probability of having OSAS. Due to its simple pictorial design with short questions, it might be suitable for screening in populations with low health literacy and in non-native English or German speakers.

Definition of a COPD self-management intervention: International Expert Group consensus.

There is an urgent need for consensus on what defines a chronic obstructive pulmonary disease (COPD) self-management intervention. We aimed to obtain consensus regarding the conceptual definition of a COPD self-management intervention by engaging an international panel of COPD self-management experts using Delphi technique features and an additional group meeting.In each consensus round the experts were asked to provide feedback on the proposed definition and to score their level of agreement (1=totally disagree; 5=totally agree). The information provided was used to modify the definition for the next consensus round. Thematic analysis was used for free text responses and descriptive statistics were used for agreement scores.In total, 28 experts participated. The consensus round response rate varied randomly over the five rounds (ranging from 48% (n=13) to 85% (n=23)), and mean definition agreement scores increased from 3.8 (round 1) to 4.8 (round 5) with an increasing percentage of experts allocating the highest score of 5 (round 1: 14% (n=3); round 5: 83% (n=19)).In this study we reached consensus regarding a conceptual definition of what should be a COPD self-management intervention, clarifying the requisites for such an intervention. Operationalisation of this conceptual definition in the near future will be an essential next step.

Integrated care: respiratory medicine ready and waiting.

A less hospital-centric approach to healthcare with specialists working nearer to patients in the community has been strongly advocated in several recent publications. In the field of respiratory medicine a team approach to the care of those with long-term respiratory conditions has been in practise for decades with such integrated approaches being shown to significantly improve outcomes. This approach is now gaining momentum with an increasing number of UK respiratory specialists undertaking sessions outside hospitals. Specific suggestions regarding the scope of this work, training, mentorship and governance have now been suggested by the specialist British Thoracic Society.

The use of an online pictorial Epworth Sleepiness Scale in the assessment of age and gender specific differences in excessive daytime sleepiness.

BACKGROUND: Excessive daytime sleepiness (EDS) is a non-specific but highly prevalent cardinal symptom of sleep disorders. We hypothesized that with modern media and an online pictorial Epworth Sleepiness Scale (ESS) age and gender specific differences of EDS could be identified on a large scale. This could be helpful in the screening of patients with sleep disorders. PATIENTS AND METHODS: In 8,098 subjects, age and gender were recorded in addition to an online pictorial ESS (range 0-24 points). The cut-off for EDS (ESS >10 points) was chosen in line with the traditional ESS. RESULTS: The prevalence of EDS was slightly higher in male subjects (45% vs. 43%, P=0.033). When age was considered, female subjects tended to be sleepier in their 3(rd) and 4(th) lifetime decade (P=0.01 and P=0.003, respectively), whilst male subjects scored significantly higher in their 7(th) decade (P<0.0001); there was a trend to more daytime symptoms with higher age (P for trend <0.001). CONCLUSIONS: The online pictorial ESS identifies gender differences in EDS and reveals increased levels of sleepiness associated with higher age. The use of modern media facilitates reaching out to the general population to raise awareness of conditions associated with EDS such as sleep apnoea.

Medicine: a rethink? Are entrants to the profession and the way it is organised fit for purpose?

The health burden in most countries has changed. Although acute care is needed for trauma, acute illness and exacerbations of chronic disease, most of the burden is now long term. These patients need different approaches, with more emphasis upon supporting self-management, enhancing lifestyle changes, aiding compliance by shared decision-making and providing more convenient follow-up that appreciates the likelihood of multimorbidity. Integrated care will increasingly be offered from within the community. The current hospital- and doctor-centric focus needs to change to one where specialists work in the community as much as in hospitals and share this different type of care with others. For potential future doctors, the scientific basis of medicine will still underpin their unique role in diagnosis and prescribing, but they will need to understand these other changes and to be selected according to attributes compatible with their future role, and then be trained and assessed accordingly.

Nurse led versus lay educators support for those with asthma in primary care: a costing study.

BACKGROUND: Regular review and support for asthma self-management is promoted in guidelines. A randomised controlled trial suggested that unscheduled health care usage was similar when patients were offered self management support by a lay-trainer or practice nurses. METHODS: Following the RCT, a costing study was undertaken using the trial data to account for the cost of delivery of the service under both strategies and the resulting impact on unscheduled healthcare (measure of effectiveness) in this trial. RESULTS: One year data (n = 418) showed that 29% (61/205) of the nurse group required unscheduled healthcare (177 events) compared with 30.5% (65/213) for lay-trainers (178 events).The training costs for the lay-trainers were greater than nurses (£36 versus £18 respectively per patient, p<0.001), however, the consultation cost for lay-trainers were lower than nurses (£6 per patient versus £24, p<0.001). If the cost of unscheduled healthcare are accounted for then the costs of nurses is £161, and £135 for lay-trainers (mean difference £25, [95% CI = -£97, £149, p = 0.681]). The total costs (delivery and unscheduled healthcare) were £202 per patient for nurses versus £178 for lay-trainers, (mean difference £24, [95%CI = -£100, £147, p = 0.707]). CONCLUSIONS: There were no significant differences in the cost of training and healthcare delivery between nurse and lay trainers, and no significant difference in the cost of unscheduled health care use.

A centralised respiratory diagnostic service for primary care: a 4-year audit.

BACKGROUND: The literature shows that delayed or erroneous diagnosis of respiratory conditions may be common in primary care due to underuse of spirometry or poor spirometric technique. The Community Respiratory Assessment Unit (CRAU) was established to optimise diagnosis and treatment of respiratory disease by providing focused history-taking, quality-assured spirometry, and evidence-based guideline-derived management advice. AIMS: To review the service provided by the CRAU to primary care health professionals. METHODS: Data from 1,156 consecutive GP referrals over 4 years were analysed. RESULTS: From the 1,156 referrals, 666 were referred for one of five common reasons: suspected asthma, confirmed asthma, suspected chronic obstructive pulmonary disease (COPD), confirmed COPD, or unexplained breathlessness. COPD was the most prevalent referral indication (445/666, 66.8%), but one-third of suggested diagnoses of COPD by the GP were found to be incorrect (161/445, 36%) with inappropriate prescribing of inhaled therapies resulting from this misdiagnosis. Restrictive pulmonary defects (56/666, 8% of referrals) were overlooked and often mistaken for obstructive conditions. The potential for obesity to cause breathlessness may not be fully appreciated. CONCLUSIONS: Misdiagnosis has significant financial, ethical, and safety implications. This risk may be minimised by better support for primary care physicians such as diagnostic centres (CRAU) or alternative peripatetic practice-based services operating to quality-controlled standards.

Self-management programmes for COPD: moving forward.

Self-management is of increasing importance in chronic obstructive pulmonary disease (COPD) management. However, there is confusion over what processes are involved, how the value of self-management should be determined, and about the research priorities. To gain more insight into and agreement about the content of programmes, outcomes, and future directions of COPD self-management, a group of interested researchers and physicians, all of whom had previously published on this subject and who had previously collaborated on other projects, convened a workshop. This article summarises their initial findings. Self-management programmes aim at structural behaviour change to sustain treatment effects after programmes have been completed. The programmes should include techniques aimed at behavioural change, be tailored individually, take the patient's perspective into account, and may vary with the course of the patient's disease and co-morbidities. Assessment should include process variables. This report is a step towards greater conformity in the field of self-management. To enhance clarity regarding effectiveness, future studies should clearly describe their intervention, be properly designed and powered, and include outcomes that focus more on the acquisition and practice of new skills. In this way more evidence and a better comprehension on self-management programmes will be obtained, and more specific formulation of guidelines on self-management made possible.

Why is spirometry underused in the diagnosis of the breathless patient: a qualitative study.

BACKGROUND: Use of spirometry is essential for the accurate diagnosis of respiratory disease but it is underused in both primary and specialist care. In the current study, we have explored the reasons for this underuse. METHODS: Five separate focus groups were undertaken with final year medical undergraduates, junior hospital doctors, general practitioners (GPs) and specialist trainees in respiratory medicine. The participants were not told prior to the session that we were specifically interested in their views about spirometry but discussion was moderated to elicit their approaches to the diagnosis of a breathless patient, their use of investigations and their learning preferences. RESULTS: Undergraduates and junior doctors rarely had a systematic approach towards the breathless patient and tended, unless prompted, to focus on the emergency room situation rather than on patients with longer term causes of breathlessness. Whilst their theoretical knowledge embraced the possibility of a non-respiratory cause for breathlessness, neither undergraduates nor junior doctors spontaneously mentioned the use of spirometry in the diagnosis of respiratory disease. When prompted they cited lack of familiarity with the use and location of equipment, and lack of encouragement to use it as being major barriers to utilization. In contrast, GPs and specialist respiratory trainees were enthusiastic about its use and perceived spirometry as a core element of the diagnostic workup. CONCLUSIONS: More explicit training is needed regarding the role of spirometry in the diagnosis and management of those with lung disease and this necessitates both practical experience and training in interpretation of the data. However, formal teaching is likely to be undermined in practice, if the concept is not strongly promoted by the senior staff who act as role models and trainers.

Understanding patients with asthma and COPD: insights from a European study.

AIMS: To understand the needs of people with asthma and COPD, and to identify opportunities for improved care. METHODS: Quantitative questionnaire-based survey performed in five European countries on patients with asthma and COPD. Questionnaires were administered to patients using Computer Assisted Web Interview methodology. RESULTS: 1022 patients with asthma (UK [n=190]; Germany [n=214]; France [n=200]; Italy [n=222]; Spain [n=196]) and 719 patients with COPD (UK [n=153]; Germany [n=147]; France [n=145]; Italy [n=140]; Spain [n=134]) were enrolled in the study. 32% of those with asthma and 67% of those with COPD considered that their condition had a significant effect on their quality of life, and stigma and emotional distress was common. Many expressed concern regarding potential medication side effects or that medicines might lose their effect with time. Major discrepancies between expectations and patient satisfaction with the doctor-patient relationship were observed, including a need to be consulted in the choice of inhalers. Consultations were infrequent, and 75% of respondents sought additional information beyond that received during consultations - commonly from the internet. CONCLUSIONS: Patient satisfaction was high but information needs were not addressed and the emotional burden of disease is underappreciated.

Promoting recruitment of minority ethnic groups into research: qualitative study exploring the views of South Asian people with asthma.

BACKGROUND: We sought to understand the barriers and facilitators to participation in research from the perspectives of South Asian people with asthma. METHODS: Eight focus groups were conducted in the preferred language of participants. Sampling was purposeful to ensure inclusion of males and females from differing ethnic, linguistic and religious backgrounds. RESULTS: The forming of trusting relationships was described as pivotal to the successful recruitment of minority ethnic groups into research; personalized approaches were likely to be better received than more impersonal written approaches. Notable barriers to participation included: the stigma of being labelled with asthma; concerns surrounding participation in pharmaceutical trials; major time or travel commitments and a failure to show respect by not making information available in minority ethnic languages. Flexibility, in terms of timing, location and respecting of cultural and religious sensitivities around gender segregation, together with the offer of incentives, were highlighted as key factors to promote participation. CONCLUSIONS: The barriers to recruitment are largely surmountable, but these will necessitate the use of resource intensive and more personalized approaches than are commonly employed for the White European origin population. Our proposed model to enhance recruitment is likely to have transferability beyond the field of asthma.
