Obesity and asthma at school entry: co-morbidities and temporal trends.

AIM: A decline in asthma prevalence from 2000 to 2005 was reported previously. The objective is to examine the temporal trends for the prevalence of obesity and other childhood disorders and consider the extent to which associations between asthma and other co-morbidities can be accounted for by body mass index. METHODS: Serial cross-sectional surveys of primary school entrants (n = 18,999) in the Australian Capital Territory between 2001 and 2005 were used. Asthma, recent respiratory symptoms and diabetes data were extracted from parental reports. Anthropometric measurements were obtained from health assessments by school nurses. Child obesity was defined using the age and sex-specific Cole criteria. Time trends for the prevalence of obesity and other disorders, and the association between 'current asthma' and co-morbidities were analysed using multiple logistic regression and other analyses. RESULTS: Obesity prevalence was 5.24% in 2001 decreasing to 3.60% in 2005 (test of linear trend P = 0.02). Overweight (adjusted odds ratio (AOR) 1.30 (95% confidence interval (CI) 1.16, 1.46), P < 0.001) and obese (AOR 1.36 (95% CI 1.13, 1.62), P = 0.001) children were more likely to report 'asthma ever'. Children with diabetes (AOR 9.35 (95% CI 3.11, 28.12, P < 0.001)) and attention deficit (AOR 3.39 (95% CI 2.04, 5.64), P < 0.001) were more likely to report 'current asthma'. CONCLUSIONS: The pattern of association with co-morbidities was different for asthma and obesity. The temporal decline/plateau effect in 'current asthma' could not be explained by concurrent body mass index changes. The decline in obesity was largely driven by the 2005 findings. Longer term trends need to be evaluated further.

Choosing to biopsy or refer suspicious melanocytic lesions in general practice.

BACKGROUND: General practitioners (GPs) are involved in the management of most melanocytic skin lesions in Australia. A high quality biopsy technique is a crucial first step in management, as it is recognized that poor techniques can mislead, delay, or miss a diagnosis of melanoma. There has been little published on the biopsy decisions and techniques of GPs. This study aims to describe the current management choices made by GPs for suspicious melanocytic skin lesions and to compare their choices with the best practice guidelines. METHODS: An anonymous survey of GPs presented with three clinical scenarios with increasing complexity of melanoma in which a referral or biopsy decision was specified. RESULTS: 391 mailed surveys with a 76.3% response rate. Mean biopsy experience was 4.14 biopsies per GP per month. The rates of choosing to refer among the three scenarios were 31%, 52% and 81% respectively, with referral to surgery being the most common choice (81%). Most biopsy techniques (55%) were chosen according to best practice guidelines, although non-guideline biopsy techniques chosen included shave (n=10), punch biopsy (n=57), wide excisions (n=65), and flaps (n=10). The few GPs (n=5) who identified themselves as skin specialist GPs were no more likely to adhere to guidelines than their colleagues. CONCLUSION: A majority of referrals and biopsies were chosen by GPs according to best practice guidelines, but concern remains for the high proportion of GPs making non-guideline based choices. How GPs choose to biopsy or refer needs further training, audit, and research if Australia is to improve the outcome of melanoma management in general practice.

Propionibacterium acnes (P. acnes) resistance and antibiotic use in patients attending Australian general practice.

BACKGROUND/OBJECTIVES: Antibiotic resistance in the community, including transfer between bacteria, is a growing concern for clinicians. Acne is commonly treated in general practice, sometimes with antibiotics. The aim of this study is to measure the rate of carriage of antibiotic resistant Propionibacterium acnes 10 years apart in general practice and the relationship of resistance to type of treatment, as well potential effects on other flora. METHODS: Patients (N = 215) with acne presenting to Australian Capital Territory and south-eastern New South Wales general practices were swabbed for P. acnes in 1997-1998 and 2007. Clinical details were collected with questionnaires. In 2007 swabs were also taken for Staphylococcus aureus and Streptococcus pneumoniae. GP's diagnostic classification of acne was tested using a set of standard photographs. RESULTS: Resistant P. acnes was isolated from 20 patients (9%) and the proportion that was resistant was the same in 1997-1998 and in 2007. Antibiotic use, particularly topical, was associated with P. acnes resistance. Resistance rates declined with the time elapsed since ceasing antibiotics. Use of retinoids was associated with a decreased chance of growing P. acnes (P = 0.008) but not with decreased resistance. Simultaneous resistance with S. aureus was not detected, but only in 30 patients was S. aureus isolated. CONCLUSIONS: P. acnes resistance was similar in 1997-1998 and in 2007.The chance of a patient carrying a resistant strain of P. acnes is significantly greater with recent exposure to antibiotics, and clinicians should limit prescribing where possible. Resistance disappears rapidly after ceasing antibiotics. Cross resistance with other organisms was not detected in this study.

Patients and tests - a study into patient understanding of blood tests ordered by their doctor.

BACKGROUND: Patient understanding of diagnostic tests is important in general practice. This study describes how patients understand information about their tests, using blood tests as an example. METHOD: A survey of patients attending two hospital blood collection centres in Canberra in the Australian Capital Territory. RESULTS: An 89% response rate (n=135): 90% of patients understood the reasons for tests but only 19% could name them; 86% reported that their doctor explained their tests and 89% reported they understood their doctor's explanation. Doctors offered 35% of patients a copy of test results. Patients who knew their general practitioner were more aware of preparations needed for undertaking blood tests (p<0.001). Thirty-six percent would seek information from the people working at blood collection centres. DISCUSSION: Patients understood the reasons blood tests were ordered, although only a few could name them. A strong relationship was found between doctors explaining blood tests and patients understanding the reasons for tests. Nevertheless, information sharing was at a low level.

Chronic disease management items in general practice: a population-based study of variation in claims by claimant characteristics.

OBJECTIVE: To describe how Medical Benefits Schedule (MBS) chronic disease (CD) item claims vary by sociodemographic and health characteristics in people with heart disease, asthma or diabetes. DESIGN, SETTING AND PARTICIPANTS: A cross-sectional analysis of linked unit-level MBS and survey data from the first 102,934 participants enrolled in the 45 and Up Study, a large-scale cohort study in New South Wales, who completed the baseline survey between January 2006 and July 2008. MAIN OUTCOME MEASURE: Claim for any general practitioner CD item within 18 months before enrolment, ascertained from MBS records. RESULTS: The proportion of individuals making claims for MBS CD items was 18.5% for asthma, 22.3% for heart disease, and 44.9% for diabetes. Associations between participant characteristics and a claim for a CD item showed similar patterns across the three diseases. For heart disease and asthma, people most likely to claim a CD item were women, older, of low income and education levels, with multiple chronic conditions, fair or poor self-rated health, obesity and low physical activity levels. The pattern of claims was slightly different for participants with diabetes in that there was no significant association with number of chronic conditions, smoking or physical activity. CONCLUSIONS: Many individuals with self-reported CD do not claim CD items. People with diabetes and individuals with greatest need based on health, socioeconomic and lifestyle risk factors are the most likely to claim CD items.

Health professionals, patients and chronic illness policy: a qualitative study.

BACKGROUND AND OBJECTIVE: This study investigates health professionals' reactions to patients' perceptions of health issues - a little-researched topic vital to the reform of the care of chronic illness. METHODS: Focus groups were undertaken with doctors, nurses, allied health staff and pharmacists (n = 88) in two Australian urban regions. The focus groups explored responses to patient experiences of chronic illness (COPD, Diabetes, CHF) obtained in an earlier qualitative study. Content analysis was undertaken of the transcripts assisted by NVivo7 software. RESULTS: Health professionals and patients agreed on general themes: that competing demands in self-management, financial pressure and co-morbidity were problems for people with chronic illness. However where patients and carers focused on their personal challenges, health professionals often saw the patient experience as a series of failures relating to compliance or service fragmentation. Some saw this as a result of individual shortcomings. Most identified structural and attitudinal issues. All saw the prime solution as additional resources for their own activities. Fee for service providers (mainly doctors) sought increased remuneration; salaried professionals (mainly nurses and allied health professionals) sought to increase capacity within their professional group. CONCLUSIONS: Professionals focus on their own resources and the behaviour of other professionals to improve management of chronic illness. They did not factor information from patient experience into their views about systems improvement. This inability to identify solutions beyond their professional sphere highlights the limitations of an over-reliance on the perspectives of health professionals. The views of patients and carers must find a stronger voice in health policy.

Following the funding trail: financing, nurses and teamwork in Australian general practice.

BACKGROUND: Across the globe the emphasis on roles and responsibilities of primary care teams is under scrutiny. This paper begins with a review of general practice financing in Australia, and how nurses are currently funded. We then examine the influence on funding structures on the role of the nurse. We set out three dilemmas for policy-makers in this area: lack of an evidence base for incentives, possible untoward impacts on interdisciplinary functioning, and the substitution/enhancement debate. METHODS: This three year, multimethod study undertook rapid appraisal of 25 general practices and year-long studies in seven practices where a change was introduced to the role of the nurse. Data collected included interviews with nurses (n = 36), doctors (n = 24), and managers (n = 22), structured observation of the practice nurse (51 hours of observation), and detailed case studies of the change process in the seven year-long studies. RESULTS: Despite specific fee-for-service funding being available, only 6% of nurse activities generated such a fee. Yet the influence of the funding was to focus nurse activity on areas that they perceived were peripheral to their roles within the practice. CONCLUSIONS: Interprofessional relationships and organisational climate in general practices are highly influential in terms of nursing role and the ability of practices to respond to and utilise funding mechanisms. These factors need to be considered, and the development of optimal teamwork supported in the design and implementation of further initiatives that financially support nursing in general practice.

Inequality in provider continuity for children by Australian general practitioners.

BACKGROUND: There is little published on provider continuity in Australian general practice and none on its effect on inequality of care for children. METHOD: Questionnaire administered to parents of the ACT Kindergarten Health Screen asking the name of their child's usual GP and practice address between 2001 and 2008. RESULTS: Parents of 30,789 children named 433 GPs and 141 practices. In each year, an average of 77% of parents could name both the GP and the practice, an average of 11% of parents could name only the practice, and an average of 12% of parents could name neither. In each year, 25% of parents could not name a usual GP for children of Aboriginal or Torres Straight Islander descent, or children born outside of Australia, compared to 10% of all other children (p = < 0.0001). The frequency of GPs displaying continuity of care varied over time with 19% of GPs being present in the ACT in only one year and 39% of GPs being present in every year over the eight years of study. GPs displayed two different forms of transience either by working in more than one practice in each year (5% of GPs), or by not being present in the ACT region from one year to the next (15% of GPs). Fewer parents nominated transient GPs as their child's GP compared to choosing GPs who displayed continuity (p < 0.001). CONCLUSIONS: Many GPs (39%) were reported to provide continuity of care for in the ACT region and some GPs (20%) displayed transient care. Indigenous children or children born outside of Australia had less equity of access to a nominated GP than all other children. Such inequity might disappear if voluntary registration of children was adopted in Australian general practice.

Views of GPs and practice nurses on support needed to respond to pandemic influenza: a qualitative study.

INTRODUCTION: Five years ago Australia, and the world, placed itself on heightened alert for pandemic influenza, based on concerns about the potential spread of the avian influenza virus. This prompted a flurry of preparation activity involving general practice, with information from various sources; government, colleges and divisions of general practice. METHOD: To assess how general practitioners and practice nurses perceive this information, practice nurses and general practitioners were interviewed as part of a larger project exploring the role of the Australian general practice sector in an influenza pandemic. Results were validated by two focus groups and scenario sessions. FINDINGS: Participants perceived that non-government organisations rarely gave useful information during a pandemic outbreak. Local divisions were perceived as having a practical and useful role, providing hands-on support to practices during a pandemic outbreak. Our participants did not perceive any coordination in the delivery of information sent by all the organisations involved in a pandemic response and therefore rejected our second hypothesis. CONCLUSIONS: More planning needs to go into the coordinated response of the general practice sector to a pandemic, and such a response should include the support of local Divisions, both as a conduit for information and to assist practices to develop response plans.

Achieving a balanced life in the face of chronic illness.

The increasing prevalence of chronic disease is a driver of health system reform in most economically advanced nations. A consistent theme within these reforms is building greater patient-centredness into the health care delivery. This study aims to develop an in-depth understanding of the experience of patients and family carers affected by chronic illness that will be the basis on which to propose policy and health system interventions that are patient-centred. Participants struggled with the ongoing tasks of balancing their lives with the increasing demands and intrusion of chronic illness. Their attempts to achieve a balance were seriously hampered by fragmented services, complexity in navigating health services, relationships with health professionals and others, and co-morbidity. Future policy directions include designing models of care and infrastructure that enable patients and their family carers to balance life and illness, and aligning patient-centred care not only within health services but also with community and social support services.

The parent-reported prevalence and management of peanut and nut allergy in school children in the Australian Capital Territory.

AIM: To describe parent-reported prevalence and management of peanut and nut allergy in school entrant children. METHOD: A population-based, cross-sectional study in the Australian National Capital. RESULTS: Out of 3851 children, parents reported 127 had a strong allergic reaction to peanuts and 19 to other nuts ever. Nut allergy ever prevalence was 3.8% (95% confidence interval 3.2-4.4%), and of peanut allergy ever 3.3% (2.8-3.9%). Children with nut allergy were more likely to have a general practitioner (odds ratio 2.64, 1.16-6.03), hay fever (3.78, 2.67-5.36), eczema (4.54, 3.15-6.56) and wheeze in the last 12 months (3.19, 2.22-4.59) and have been breastfed (2.68, 1.26-5.77) than those who did not. At follow up of 109 children with parent-reported allergy (75% response), 70% had diagnostic test-confirmed sensitisation, 32% had been prescribed an adrenalin autoinjector (6% had used one) and 46% were not eating peanut. Increasing severity of reported symptoms following consumption of peanut was associated with an increasing likelihood of recommended management. Based on parent report, the projected estimated diagnostic test-confirmed prevalence of peanut sensitisation was 2.4% (1.9%, 3.0%) for the entire sample. CONCLUSION: Among a highly representative sample of children at school entry, 1 in 30 parents reported their child to have a strong allergic reaction to nuts and over 1 in 50 are estimated to have diagnostic test-confirmed peanut sensitisation, based on parent report.

Challenges for co-morbid chronic illness care and policy in Australia: a qualitative study.

BACKGROUND: In response to the escalating burden of chronic illness in Australia, recent health policies have emphasised the promotion of patient self-management and better preventive care. A notable omission from these policies is the acknowledgment that patients with chronic illness tend to have co-morbid conditions. Our objectives were: to identify the common challenges co-morbidity poses to patients and carers in their experiences of self-management; to detail the views and perceptions of health professionals about these challenges; and to discuss policy options to improve health care for people with co-morbid chronic illness. The method included semi-structured interviews and focus groups with 129 purposively sampled participants. Participants were people with Type 2 diabetes, chronic obstructive pulmonary disease and/or chronic heart failure as well as carers and health care professionals. Content analysis of the interview data was conducted using NVivo7 software. RESULTS: Patients and their carers found co-morbidity influenced their capacity to manage chronic illness in three ways. First, co-morbidity created barriers to patients acting on risk factors; second, it complicated the process of recognising the early symptoms of deterioration of each condition, and third, it complicated their capacity to manage medication. CONCLUSION: Findings highlight challenges that patients with multiple chronic conditions face in relation to preventive care and self-management. Future clinical policy initiatives need to move away from single illness orientation toward strategies that meet the needs of people with co-morbid conditions and strengthen their capacity to self-manage. These patients will benefit directly from specialised education and services that cater to the needs of people with clusters of co-morbidities.

GP interest in teaching junior doctors - Does practice location, size and infrastructure matter?

BACKGROUND: With the influx of Australian medical graduates into the workforce, new clinical prevocational training rotations within general practice need to be developed. This study describes the relationship between general practitioner teachers' interest in hosting junior doctor rotations, and general practice characteristics including rural location, size and infrastructure. METHOD: All GP teachers of registrars and medical students in the Australian Capital Territory and southeast New South Wales were sent a survey. The features of rural location, size and infrastructure of these teachers' general practices were analysed to determine their influence on teacher interest in hosting junior doctor rotations. RESULTS: Factors such as rural location and infrastructure did not influence willingness to host junior doctors significantly. However, those in medium sized practices were less interested than small or large practices. DISCUSSION: Rural location and teaching room infrastructure of practices need not be determinants in junior doctor teaching practice recruitment, while medium practice size is a significant determinant of lack of teacher interest in hosting junior doctors. This requires further investigation.

Contributions from the lifeworld: quality, caring and the general practice nurse.

INTRODUCTION: Enhancing quality and safety in primary health systems is of central importance to funders, practitioners, policy makers and consumers. In this paper we explore the roles of general practice nurses in relation to quality and safety. METHOD: Cross-sectional multimethod study of 25 Australian general practices. Using rapid appraisal we collected data for each practice from interviews with practice nurses, general practitioners and practice managers; photographs of nurse-identified 'key workspaces'; structured observation of nurses for two one-hour sessions; and floor plans. RESULTS: Quality was articulated in two domains, reflecting both external and intrinsic determinants. External determinants included a large number of essentially structural, procedural or regulatory processes, the most marked of these being practice accreditation and occupational health and safety; these corresponded to the Habermasian idea of system. Intrinsic determinants related mostly to nurse perception of their own quality behaviour, and consisted of ways and means to improve or optimise patient care; these correspond to Habermas' notion of the lifeworld. DISCUSSION: Nurses describe a productive tension between the regulatory roles that they play in general practices, and patient-focused care, contrary to Habermas' suggestion that system subsumes lifeworld. Current funding systems often fail to recognise the importance of the particular elements of nurse contributions to quality and safety in primary care.

Models in the delivery of depression care: a systematic review of randomised and controlled intervention trials.

BACKGROUND: There is still debate as to which features, types or components of primary care interventions are associated with improved depression outcomes. Previous reviews have focused on components of collaborative care models in general practice settings. This paper aims to determine the effective components of depression care in primary care through a systematic examination of both general practice and community based intervention trials. METHODS: Fifty five randomised and controlled research trials which focused on adults and contained depression outcome measures were identified through PubMed, PsycInfo and the Cochrane Central Register of Controlled Trials databases. Trials were classified according to the components involved in the delivery of treatment, the type of treatment, the primary focus or setting of the study, detailed features of delivery, and the discipline of the professional providing the treatment. The primary outcome measure was significant improvement on the key depression measure. RESULTS: Components which were found to significantly predict improvement were the revision of professional roles, the provision of a case manager who provided direct feedback and delivered a psychological therapy, and an intervention that incorporated patient preferences into care. Nurse, psychologist and psychiatrist delivered care were effective, but pharmacist delivery was not. Training directed to general practitioners was significantly less successful than interventions that did not have training as the most important intervention. Community interventions were effective. CONCLUSION: Case management is important in the provision of care in general practice. Certain community models of care (education programs) have potential while others are not successful in their current form (pharmacist monitoring).

Practising GPs teaching medical students evidence based medicine--a questionnaire survey.

BACKGROUND: The characteristics of practising general practitioners who teach evidence based medicine (EBM) during their clinical work--and their attitudes toward it--are poorly known. METHODS: One hundred and twenty-two Canberra GPs who previously had medical students attend their practice were sent a questionnaire on their education, experience, knowledge, confidence, and attitudes toward teaching EBM. RESULTS: Eighty-three (68%) GPs responded, 13% had postgraduate EBM training, and 20% taught EBM. A further 28% of GPs denied they were teachers of EBM but had asked students to find evidence to answer questions about patient care. Seventy-six percent of GPs could understand and explain at least one EBM term, and 17% over five terms. Most GPs welcomed EBM into their clinical work and agreed EBM improved students' learning. Barriers to teaching included a perceived lack of time, staff support, and the need for more EBM teacher training. DISCUSSION: Although few GPs had trained in EBM, many were teaching it. University teaching programs should build on GP confidence in EBM teaching.

Recognition of physical and psychological symptoms--no influence of GP demographic factors.

AIM: To describe the relationship between general practitioner demographic factors and the recognition of psychological and physical symptoms in consultation. METHODS: A survey of a random sample of 70 GPs and their patients (n=3414) from the lower North Island of New Zealand. RESULTS: No relationship was found between GP personal and practice demographic characteristics and GP identification of psychological and physical symptoms. Patients were more likely not to present psychological symptoms (62%) than not present physical symptoms (5%) in consultation. Thirteen percent of GPs wanted more formal psychiatric training, 45% wanted more contact time in consultation, and 72% thought that cost was a barrier to patients attending. No significant relationship was found between these factors and GP detection of significant psychological symptoms in consultation. DISCUSSION: Personal and practice demographics of GPs may not predict their ability to detect physical and psychological symptoms. More research is needed to explore these findings which contradict previous work.

Quality of diagnostic coding and information flow from hospital to general practice.

AIMS: To describe the transfer of patient information from hospital to general practice and compare the quality of coding of patient diagnoses in hospital and general practice systems. SETTING: Wellington Hospital and patients registered with 12 general practitioners (GPs) from two local computerised general practices. Discharge and outpatient letters for the period June to August 2003 were analysed and diagnostic coding compared between letters and electronic health records (EHR) in hospital and general practice. A questionnaire was sent to 167 consultants and 112 GPs from Wellington city region with a 71% response rate. RESULTS: GPs received 55% of 284 discharge letters and 97% of 612 outpatient letters with a mean time of 9.4 days (range 0-70 days) and 14 days (range 0-120 days). The mean number of diagnostic codes recorded in discharge letters was 2.9 per letter, in the GPs' EHR 0.9 per letter, and in the hospital EHR 3.5 per letter. GPs were sent new diagnostic information in 30% of discharge and 36% of outpatient letters. There was more coding agreement between GPs' EHR and discharge letters than between the hospital EHR and discharge letters (65% versus 35%). GPs duplicated coding for 71% of all letters, and 74% of diagnoses were coded within the classification section of the GPs' EHR. More GPs than hospital doctors coded patient diagnoses (85% versus 15%), had any formal training in coding (25% versus 2%), and thought coding improved patient care (75% versus 50%). Most doctors in both groups experienced considerable delay of information flow and favoured an electronic transfer of information. CONCLUSIONS: There is delay in information flow from hospital to general practice and poor comparison of diagnostic coding across the two systems. Attitudinal differences and inefficient coding practices will need to be addressed to produce an integrated information system between hospital and general practice.

Single cases in general practice and general medical journals.

OBJECTIVE: To compare single cases published in general practice and general medical journals. METHODS: A systematic review of single cases in nine general practice and four general medical journals and a qualitative investigator triangulation for content. RESULTS: Just over seven percent of 10,607 publications involved single cases in both journal groups. Single cases were mainly published as reports or reviews in general practice journals and letters in general medical journals. Two percent of single cases were published as original research papers in general medical journals and none in general practice journals. No journal was prescriptive on the data elements required of a case write-up and few provided guidelines as to consent needs. Patient gender was reported in 97%, age in 85%, occupation in 17%, ethnicity in 10%, and consent in 5% of cases. Twelve percent of authors were general practitioners and 72% were specialists. Authors in general practice journals knew their cases longer compared with those in general medicine journals. General practitioners published over a wide range of case types including diagnostic error and relationship cases. In contrast, specialists published mainly on harm or unusual case types, but none on relationships. CONCLUSION: Single cases are common in the medical literature. The reporting of data elements (particularly consent) needs improvement. Comparatively few GPs publish single cases.

The presence of medical students in practice consultations. Rates of patient consent.

OBJECTIVE: To measure the frequency of nonconsent encountered by medical students and describe the influence of gender. METHOD: An observational study of general practice teaching consultations. SUBJECTS: 63 students (40% female), 67 general practitioners (30% female), and 2572 patients (56% female). OUTCOME: 3.4% of all patients (79% female) did not give consent (4.6% for male students; 1.6% for female; OR = 3.0, 95% CI 1.7-5.3). The rates of nonconsent did not vary between age groups for men but occurred mainly in the 15-44 years age group for women. Male students encountered more nonconsenting female patients than female students, particularly in consultations with female GPs. CONCLUSION: Consent to allow medical students to be present in general practice consultations is usually provided. It is typically declined for male students by young women attending women doctors.
