A mixed methods study to compare models of spirometry delivery in primary care for patients at risk of COPD

Background: To increase recognition of airflow obstruction in primary care, we compared two models of spirometry delivery in a target group at risk of chronic obstructive pulmonary disease (COPD). Methods: A 6 month qualitative/quantitative cluster randomised study in eight practices compared opportunistic spirometry by “visiting trained nurses” (TN) with optimised “usual care” (UC) from general practitioners (GPs) for smokers and ex-smokers, aged over 35 years. Outcomes were: spirometry uptake and quality, new diagnoses of COPD and GPs’ experiences of spirometry. Results: In the eligible target population, 531/904 (59%) patients underwent spirometry in the TN model and 87/1130 (8%) patients in the UC model (p<0.0001). ATS spirometry standards for acceptability and reproducibility were met by 76% and 44% of tests in the TN and UC models, respectively (p<0.0001). 125 (24%) patients tested with the TN model and 38 (44%) with the UC model reported a pre-existing respiratory diagnosis (p<0.0001). Three months after spirometry, when the ratio of forced expiratory volume in 1 s/forced vital capacity (FEV1/FVC) was <0.7 and no prior COPD diagnosis was reported, nine (8%) participants had a new doctor recorded COPD diagnosis in practices with the TN model and two (8%) participants in practices with the UC model. Mislabelling of participants with a diagnosis of COPD when FEV1/FVC was ⩾0.7 was present in both models prior to and after spirometry. GPs valued high quality spirometry and increased testing of patients at risk of COPD in the TN model. They identified limitations, including the need for better systematic follow-up of abnormal spirometry and support with interpretation, which may explain persisting underdiagnosis of COPD in practice records. Conclusions: Although opportunistic testing by visiting trained nurses substantially increased and improved spirometry performance compared with usual care, translating increased detection of airflow obstruction into diagnosis of COPD requires further development of the model.

Factors associated with initiation and exclusive breastfeeding at hospital discharge: late preterm compared to 37 week gestation mother and infant cohort

BackgroundTo investigate and examine the factors associated with initiation of, and exclusive breastfeeding at hospital discharge of, late preterm (34 0/7 - 36 6/7 weeks) compared to 37 week gestation (37 0/7 - 37 6/7 week) mother and baby pairs.MethodsA retrospective population-based cohort study using a Perinatal National Minimum Data Set and clinical medical records review, at the Royal Hobart Hospital, Tasmania, Australia in 2006.ResultsLate preterm and 37 week gestation infants had low rates of initiation of breastfeeding within one hour of birth, 31 (21.1%) and 61 (41.5%) respectively. After multiple regression analysis, late preterm infants were less likely to initiate breastfeeding within one hour of birth (OR 0.3 95% CI 0.1, 0.7 p = 0.009) and were less likely to be discharged exclusively breastfeeding from hospital (OR 0.4 95% CI 0.1, 1.0 p = 0.04) compared to 37 week gestation infants.ConclusionA late preterm birth is predictive of breastfeeding failure, with late preterm infants at greater risk of not initiating breastfeeding and/or exclusively breastfeeding at hospital discharge, compared with those infants born at 37 weeks gestation. Stratifying breastfeeding outcomes by gestational age groups may help to identify those sub-populations at greatest risk of premature cessation of breastfeeding.

Visual Art in Physical Rehabilitation: Experiences of People with Neurological Conditions

Aims: The aims of this study were to understand the experience of participation in visual art from the perspective of adults undergoing outpatient physical rehabilitation and to determine whether art has a place in this context. Method: This qualitative study involved interviewing adults who attended a weekly art class run by a qualified art teacher and occupational therapists in an outpatient physical rehabilitation setting. Nine participants with neurological conditions discussed their experience of the programme and the goals they were working towards or had achieved through painting. Findings: The themes that emerged from the study show that art contributed to the participants meeting their individual rehabilitation goals. It also assisted the participants in using time, increasing enjoyment, regaining confidence and planning for engagement in future activities. All these achievements were seen by the participants to contribute to their rehabilitation or recovery. The identified themes align with the aims of rehabilitation and are similar to findings from many other studies investigating the use of art by people affected by illness or disability. Conclusion: The findings of this study inform clinical practice in the use of visual art with clients in rehabilitation and validate its place in a physical rehabilitation programme.

Cumulative risks and cessation of exclusive breast feeding: Australian cross-sectional survey

Objectives To estimate the prevalence of cessation of exclusive breast feeding at each month up to 6 months and document key factors and cumulative risks associated with exclusive breastfeeding cessation for children aged from 0 to 6 months. Methods Secondary analysis using a national representative sample of 22 202 mother and infant pairs derived from the 2010 Australian Institute of Health and Welfare cross-sectional survey, the Australian Infant Feeding Survey. Results Among breastfed infants, 49% had ceased exclusive breast feeding before they had reached 2 months of age. In the final Cox proportional hazards model, cessation of exclusive breast feeding was most strongly associated with partners preferring bottle feeding (HR 1.86, 95% CI 1.69 to 20.6) or having no preference (HR 1.37, 95% CI 1.33 to 1.42), regular dummy use (HR 1.35, 95% CI 1.31 to 1.39) and maternal obesity (HR 1.29, 95% CI 1.24 to 1.35). Living within the most disadvantaged areas of Australia (quintile 1) was not strongly associated with cessation (HR 1.08, 95% CI 1.02 to 1.14) compared with least disadvantaged areas. Having three risk factors significantly increased the risk of cessation by 31% (HR 1.31, 95% CI 1.07 to 1.6). Conclusions The prevalence of early cessation of exclusive breast feeding is alarmingly high with 50% of infants no longer exclusively breast fed by age 2 months. Given that not one factor is associated with cessation of exclusive breast feeding, the greatest public health impact is likely to be achieved when multiple risk factors are modified or prevented.

Evaluating effectiveness of arts and health programmes in Primary Health Care: a descriptive review

Primary Objective: This descriptive review investigated how arts and health programmes and projects in Primary Health Care evaluate their effectiveness. A systematic search was undertaken of articles and reports that reported results from arts and health project and programme evaluations in Primary Health Care settings from 2004 to 2009. Twenty-nine articles or reports met the inclusion criteria. These articles were analysed to identify the characteristics of the evaluations, evaluation tools used, and what the evaluations measured. Main outcomes and results: The review found that a range of different approaches, models and designs are used to evaluate arts and health programmes or projects in Primary Health Care. Questionnaires and interviews were the most common data collection tools used, with a majority of studies using qualitative or mixed methods. The review also identified three main approaches in terms of what factors were measured: measuring the programme objectives, measuring for specific health status or health factors and measuring the experience. Conclusions: The focus on arts and health evaluation to date has largely been to justify funding or prove that the art in the health arena is worthwhile or cost-effective. As arts and health becomes established as its own area of practice we face the challenge of ascertaining how to best evaluate such programmes.

How do women change osteoporosis-preventive behaviours in their children?

Objective:We have reported that a lifestyle intervention with mothers improved calcium intake and physical activity in both mothers and their children. In this study, we aimed to describe the strategies and approaches used by these mothers to improve their childrens calcium intake and physical activity.Design:A qualitative study using semistructured interviews.Setting:Population-based convenience sample.Subjects:A subsample of 39 mothers were taken from a population-based random sample of 354 mothers who had participated in the original osteoporosis-prevention trial.Results:Mothers described specific dietary changes they made to increase their childrens calcium intake. They also described strategies for improving calcium intake and physical activity such as raising awareness of the importance of calcium; ensuring calcium-rich foods were accessible; assessing their childrens likes and dislikes and working within these; role modelling; information provision; taking a balanced approach to attempting behaviour change; and encouraging activities that they could do with their children. Mothers emphasized the general importance of a balanced diet and lifestyle, rather than just focussing on lifestyle factors specific to osteoporosis prevention.Conclusion:Even without specific guidance, mothers are adept at developing strategies to apply to changing lifestyle behaviours in their children and identifying barriers to change. These results provide information, which could be incorporated into future interventions for lifestyle change in children and also provide further support for considering parent-focused approaches to this problem.

Staying a smoker or becoming an ex-smoker after hospitalisation for unstable angina or myocardial infarction

The aim of our study was to better understand processes of ongoing smoking or smoking cessation (quitting) following hospitalisation for myocardial infarction or unstable angina (acute cardiac syndromes). In-depth interviews were used to elicit participants’ stories about ongoing smoking and quitting. In total, 18 interviews with smokers and 14 interviews with ex-smokers were analysed. Our findings illustrate the complex social nature of smoking practices including cessation. We found that smoking cessation following hospitalisation for acute cardiac syndromes is to some extent a performative act linked to ‘doing health’ and claiming a new identity, that of a virtuous ex-smoker in the hope that this will prevent further illness. For some ex-smokers hospitalisation had facilitated this shift, acting as a rite of passage and disrupting un-contemplated habits. Those participants who continued to smoke had often considered quitting or had even stopped smoking for a short period of time after hospitalisation; however, they did not undergo the identity shift described by ex-smokers and smoking remained firmly entrenched in their sense of self and the pattern of their daily lives. The ongoing smokers described feeling ashamed and stigmatised because of their smoking and felt that quitting was impossible for them. Our study provides an entry point into the smokers’ world at a time when their smoking has become problematised and highly visible due to their illness and when smoking cessation or continuance carries much higher stakes and more immediate consequences than might ordinarily be the case.

Whole person care, patient-centred care and clinical practice guidelines in general practice

ABSTRACT Clinical practice guidelines (CPGs) are a central technique within the evidence-based medicine (EBM) movement. General practice is an area of medicine that seems to be particularly resistant to the use of CPGs. This article contributes to the debates about GPs and CPGs by reflecting on three different Australian studies conducted by the authors in an attempt to better understand variations between GPs’ practices and the recommendations found in relevant CPGs. These projects focused on dementia, chronic obstructive pulmonary disease and hypertension (high blood pressure). A common finding across the three studies was that GPs described how their focus on the whole person and their patients’ priorities and needs meant that the recommendations found in CPGs were not always appropriate or easy to apply. In doing this, our study participants were describing tensions between the holistic/whole person and patient-centred approach of GPs and the narrow disease-specific focus of guidelines. Our work provides insight into the rationality of GPs and illustrates some of the ways that whole person care and patient-centred care create operational challenges to the application of EBM in the form of CPGs.

Australian women’s experiences of smoking, cessation and ‘cutting down’ during pregnancy

ABSTRACT This article presents an analysis of interviews with Australian women who had smoked or were currently smoking during pregnancy. It explores how they spoke about their experiences of smoking, cessation and harm minimisation during pregnancy. Eighteen women underwent a single in-depth interview, these were analysed using an iterative thematic method. We found that smoking, cessation and harm minimisation by pregnant women are complex social practices. Participants viewed smoking as a potential risk to fetal health and as an actual risk to their own health and described feeling embarrassed and ashamed of smoking when pregnant. Their opinions about the relative seriousness of health risks posed by smoking when pregnant were often informed by their own personal observations and experiences. Participants used this knowledge to engage in lay epidemiological processes as they rationalised and made sense of the relative risks of smoking, quitting or cutting down. They also sought legitimacy for their claims about the safety of quitting or cutting down in two potentially contradictory ways. These were personal experience/observations and medical advice. Our findings contribute to sociological understanding about lay responses to medical advice on smoking in pregnancy and will be of value to healthcare professionals who work with pregnant women.

Young adult perceptions of Australia's physical activity recommendations for adults.

ISSUES ADDRESSED Physical activity recommendations for adults worldwide advise participation in moderate-intensity physical activity, such as walking, on most days of the week. Younger adults report the lowest prevalence of walking. This mixed-methods study explores the salience of Australias activity recommendations around moderate-intensity physical activity, particularly walking, for young Australian adults. METHODS Semistructured interviews were conducted with 24 young Australians aged 17-25 years. During interviews, Australias physical activity recommendations for adults were explained to participants, highlighting the inclusion of moderate-intensity physical activity such as walking. Participants were asked to comment on the recommendations and walking for physical activity and exercise. Data from interviews underwent an iterative thematic form of analysis. Participants also completed the International Physical Activity Questionnaire (IPAQ) and were asked to complete a pedometer diary. RESULTS No participant was classified as sedentary; twenty three participants reported walking for transport and nine for leisure (IPAQ). During interviews, the majority of participants (n=20) did not identify walking as physical activity or exercise. Participants focussed on the cardiorespiratory (fitness) benefits associated with physical activity and believed walking was of insufficient intensity to achieve these benefits at their age. CONCLUSIONS Walking was considered an everyday activity and of insufficient intensity to achieve any health or fitness benefits. SO WHAT?: The belief that only vigorous physical activity conveys any fitness benefits may act as a barrier to participation in moderate-intensity physical activity such as walking, particularly among sedentary young people.
