Self-management support? Listening to people with complex co-morbidities.

OBJECTIVES: The study aimed to explore how people with complex, established co-morbidities experience long-term condition care in New Zealand. Despite the original conception as appropriate for people with early stage disease, in New Zealand the self-management approach dominates the care provided to people at all stages of diagnosis with long-term conditions, something reinforced through particular funding mechanisms. METHODS: A multiple case study followed the lives of 16 people with several long-term conditions. Data collection comprised two interviews, four weekly contacts with patients over an 18-month period and an interview with their primary health care clinicians. RESULTS: This paper reveals a cohort of tired, distracted patients struggling to manage their lives in the face of multiple conflicting challenges, with insufficient energy for the level of personal agency required to deal with the self-management approach. DISCUSSION: Participants described aspects of care received, which does meet their needs but sit outside the self-management approach, that resonate with the ideas behind current approaches to palliative care. The potential of an approach to care built upon these ideas is explored as a more compassionate, effective way of meeting the needs of people with advanced, multiple long-term conditions. Further research is warranted to explore the acceptability of such an approach.

The complexity of food for people with multiple long-term health conditions.

INTRODUCTION The prevalence of long-term health conditions (LTCs) continues to increase and it is normal for people to have several. Lifestyle is a core feature of the self-management support given to people with LTCs, yet it seems to fail to meet their needs. From a larger study exploring the experiences of this group, this paper reports on the role of food and mealtimes, and the effect of the nutritional advice on the lives of people with several LTCs. METHODS The experiences of 16 people with several advanced LTCs were explored using multiple qualitative case studies. Over an 18-month period, contact with participants included monthly conversations, two longer, semi-structured interviews and one interview with their primary care clinicians. The data were analysed inductively using thematic analysis. RESULTS There was profound social, psychological and cultural significance of food to the participants. These aspects of food were then described using the Whare Tapa Wha model of health. The approach to food and nutrition participants experienced in health care was closely associated with conventional weight management. They found this advice largely irrelevant and therefore ineffective. DISCUSSION The pressure people with several LTCs experience during clinical encounters has perverse effects on wellbeing and reinforces an overall sense of failure. This research challenges the assumption that all people have the will, agency and income to follow the advice they receive about nutrition and exercise. Considering people's needs using the Whare Tapa Wha model of health offers clinicians a framework to re-conceptualise the core features of self-management support and provide realistic, compassionate care that will optimise the quality of life for people with multiple LTCs.

Measuring care alignment in general practice consultations for people with long-term conditions: an exploratory study.

INTRODUCTION Chronic care Model (CCM) aims to make the care of people with long term conditions (LTC) planned, proactive and patient-centred. The patient assessment of chronic care (PACIC) and our recently developed modified PACIC (MPACIC) allow patient and provider views to be compared. AIM To explore the use of measures of care provision and receipt in primary care long-term conditions management and to assess congruity between patient and provider views of support. METHODS For this observational self-report study, 13 pairs of matched patient and provider dyads (patient/general practitioner and patient/practice nurse) were recruited from general practice. Patients with long-term conditions were asked to rate the support provided by their general practitioner and practice nurse, separately, using the PACIC instrument, a measure of care processes. The modified version for providers (MPACIC) was similarly administered, with GPs and PNs (herein referred to as practitioners) rating the care specifically provided to the 13 patients. Aggregated scores were compared and a case study example was used. RESULTS For 67% of ratings, patients and practitioners agreed (0 or 1 category difference) on the frequency of self-management support provision. Some disagreement was found for 19% of ratings, and considerable disagreement was found for 15%. The strongest agreement was found with Delivery System Design and the least with Goal Setting. Generally, there was little difference between patient/doctor and patient/nurse agreement. DISCUSSION Agreement between patients and practitioners regarding the level of self-management support received and provided was relatively high. This study demonstrates ways the PACIC and MPACIC can be used together to measure patient/practitioner agreement about long-term condition care provision.

Occupational asthma and the paper recycling industry.

BACKGROUND: Occupational disease linked to the paper recycling industry has not been well documented. No previously confirmed formal diagnosis of occupational asthma (OA) caused by hydroxylamine has been made. METHODS: We have assessed and performed occupational assessment of eight workers involved in this industry. Two of these were later diagnosed with OA and are reported here. RESULTS: Both workers developed their respiratory symptoms within 2 years of the first use of the chemical hydroxylamine as part of the 'de-inking' process. Hydroxylamine was used as a substitute for glutaraldehyde on risk grounds, although no prior cases of OA had been found. The two workers had worked at the same plant for 11 and 20 years, respectively. Both gave histories of work-related wheeze, shortness of breath and cough. Both cases performed OASYS peak flow records over a 3-week period and had OASYS II index of 2.85 and 2.67, respectively. Both were redeployed on site to non-exposed areas and subsequently demonstrated improvement in bronchial reactivity. Case 2 subsequently consented to and underwent a blinded, placebo-controlled occupational challenge using hydroxylamine demonstrating a significant isolated late asthmatic response. CONCLUSIONS: We believe that these are the first two confirmed cases of OA caused by hydroxylamine in the paper recycling industry.

Prevalence of airflow obstruction in patients attending a rapid access chest pain clinic.

BACKGROUND: Many UK hospitals have set-up specialised chest pain clinics to deal promptly and efficiently with cases of possible cardiac chest pain. It is possible that a proportion of patients attending these clinics will have a respiratory cause for their chest pain, or respiratory disease in addition to their cardiac pain. This study aimed to determine the prevalence of airflow obstruction, ischaemic heart disease and dual pathology in such patients. METHODS: Spirometry was performed on patients referred to a rapid access chest pain clinic over a 12-month period (target population of 400 patients). The main outcome measure was the prevalence of airflow obstruction (defined using spirometry), ischaemic heart disease and dual pathology. RESULTS: 405 subjects participated in the study. Abnormal spirometry was detected in 21% of patients (n=85). Airflow obstruction was the predominant lung function abnormality and was detected in 60 patients. Ischaemic heart disease was diagnosed in 21% of patients (n=85). Dual pathology was found in 4% of patients (n=17). CONCLUSIONS: Previous studies have reported a link between impaired lung function and future cardiovascular morbidity and mortality. This study suggests that airflow obstruction is an important alternative differential diagnosis in patients referred to a rapid access chest pain clinic. The identification of abnormal spirometry may help to better risk-stratify patients for future cardiovascular events and allow interventions to be instituted.

Prevalence of respiratory symptoms, features of asthma, and characteristics associated with respiratory disease, in 6-11 year olds in Manchester.

AIMS: This paper describes the prevalence of respiratory symptoms, features of asthma, and characteristics associated with respiratory disease in 6-11 year old children in an historical cohort study. METHODS: The study included 5086 children, all born in the same maternity unit in the north west of England over a four-year period. The prevalence of respiratory symptoms, features of asthma, and characteristics associated with respiratory disease were determined by the use of parent-completed questionnaires. Skin prick tests were used to ascertain atopic status. RESULTS: The response was 47.5%. The prevalence of wheeze, asthma medication use and atopic sensitisation were 20.3%, 16.2% and 37.1% respectively. Wheeze and atopy were significantly more prevalent in boys (22.4% versus 17.9% and 43.0% versus 29.3%, respectively). CONCLUSIONS: This study identified a high prevalence of respiratory disease in this population and provides a baseline for monitoring trends in respiratory disease in 6-11 year old children.

Natural history and risk factors of early respiratory responses to exposure to cotton dust in newly exposed workers.

OBJECTIVE: A prospective study of newly exposed cotton workers was performed to investigate the natural history of respiratory symptoms and lung function changes. METHODS: A total of 157 workers naive to cotton dust exposure were investigated by questionnaire, spirometry, and skin tests. They were examined before employment (baseline) and at the end of the first week, and the first, third, sixth, and 12th month after starting work. Acute airway response was defined as either a cross-first-shift or a cross-week fall in forced expiratory volume in one second (FEV1). The longitudinal change of lung function over the year was also calculated. Five hundred seventy-two personal dust sampling and 191 endotoxin measurements were performed to assess the exposure. RESULTS: Forty percent of workers reported work-related symptoms in the first week of the study. Smoking, endotoxin, and dust concentrations were risk factors for all work-related symptoms. Acute airway responses were witnessed after immediate exposure. Female status was the only factor found to be predictive of acute airway response. The mean longitudinal fall in FEV1 at 1 year was 65.5 mL (standard error = 37.2). Age, early respiratory symptoms, and early fall in cross-week FEV1 were found to predict the 12-month fall in FEV1. Cross-first-shift and cross-week falls in FEV1 reduced in magnitude during the course of the study. CONCLUSIONS: This study of workers naive to cotton dust exposure has demonstrated that respiratory symptoms and acute airway responses develop early following first exposure, and a tolerance effect develops in those workers with the continued exposure. Current smoking and increasing exposure predicts the development of work-related lower respiratory tract symptoms, while early symptoms and acute airway changes across the working week predict the longitudinal loss of lung function at 1 year.

Is the prevalence of wheeze in children altered by neonatal BCG vaccination?

BACKGROUND: The prevalence of asthma and atopic disease has increased in recent decades, but precise reasons for this increase are unknown. BCG vaccination is thought to be among a group of vaccines capable of manipulating the immune system toward T(H)1 dominance and therefore reducing the likelihood of atopic disease. OBJECTIVE: The aim of this study was to determine the influence of neonatal BCG vaccination on the prevalence of wheeze in a large community population of children. METHOD: In a historical cohort study, a parent-completed questionnaire was used to identify the prevalence of wheeze in BCG-vaccinated and nonvaccinated children in Manchester, England. RESULTS: There were 2414 participants aged between 6 and 11 years. In a univariate analysis neonatal BCG vaccination was associated with a significantly lower prevalence of wheeze (odds ratio, 0.69; 95% CI, 0.55-0.86), and statistical significance was retained when the analysis was adjusted for potential confounders (odds ratio, 0.68; 95% CI, 0.53-0.87). CONCLUSION: These results demonstrate an association between asthma symptom prevalence and neonatal BCG vaccination, relating to a possible 27% reduction in prevalence, and are therefore of considerable public health importance. CLINICAL IMPLICATIONS: The capacity of neonatal BCG vaccination to reduce the prevalence of respiratory symptoms in children warrants further investigation.

IPEADAM study: indoor endotoxin exposure, family status, and some housing characteristics in English children.

BACKGROUND: Many environmental factors have been investigated to determine their involvement in the asthma epidemic. OBJECTIVE: We sought to investigate the indoor environment of English children. METHOD: The Indoor Pollutants, Endotoxin, Allergens, Damp and Asthma in Manchester (IPEADAM) study recruited 200 asthmatic and age-, sex-, and sibship size-matched nonasthmatic children after a questionnaire-based community screening epidemiology survey. Their homes were sampled for several indoor air factors, and reservoir dust samples were obtained. Endotoxin, Der p 1, and dampness levels were assayed. Questionnaires were administered to record housing characteristics. Indoor pollutants, including environmental tobacco smoke, volatile organic compounds, nitrogen dioxide, formaldehyde, temperature, and relative humidity, were investigated. STATA univariate and multivariate analyses were used to compare the indoor environments of the children. RESULTS: The levels of endotoxin (adjusted odds ratio, 1.88; 95% CI, 1.11-3.18; P=.018), living in a single-parent family (adjusted odds ratio, 3.89; 95% CI, 1.25-12.1; P=.019), redecoration in the living room (adjusted odds ratio, 3.15; 95% CI, 1.36-7.33; P=.008), and self-reported absence of dampness (adjusted odds ratio, 0.36; 95% CI, 0.14-0.91; P=.030) were all independent predictive factors of asthma. There was no difference between asthmatic and healthy children in their exposure to Der p 1, objective measurements of dampness, guardian's smoking habits, pet ownership, house type or age, time in residence, central heating systems, insulation types, glazing systems, floor types, and age and measurements of several indoor pollutants. CONCLUSION: The IPEADAM study has shown that there were very few differences in the indoor environments of English asthmatic and nonasthmatic children. However, once asthma has been established, the presence of endotoxin is positively associated with an asthmatic child's living room carpet reservoir dust. CLINICAL IMPLICATIONS: There are no direct clinical implications of this research, although it needs interpreting with other clinical data on endotoxin exposure in epidemiologic settings.
