Anxiety, panic and adult asthma: a cognitive-behavioral perspective.

A review of previous research suggests increased probability of the prevalence of anxiety disorders, and particularly panic disorder and panic attacks in patients with asthma, as compared to a normal population. Research also indicates significant levels of co-morbidity between asthma and anxiety as measured on dimensional scales of anxiety and panic. Clinical anxiety and panic manifestations affect symptom perception and asthma management through the effects of anxiety symptoms such as hyperventilation, and indirectly through self-management behavior and physician response. However, there is limited data on the impact of anxiety co-morbidity on asthma quality of life. Some studies indicate that individuals with co-morbid asthma and anxiety or panic report worse asthma quality of life both in general and in relation to their symptomatology, being limited in their daily activities, in response to environmental stimuli and in regard to feelings of emotional distress. Cognitive-behavioral therapy (CBT) is an effective and empirically supported treatment of choice for anxiety disorders and panic attacks. However, standard CBT protocols for anxiety and panic may need to be specifically targeted at improving asthma outcomes. Also, asthma research literature is lacking in randomized controlled trials applying CBT to patients with co-morbid asthma and clinical anxiety manifestations. Trials evaluating CBT interventions in individuals with clinical anxiety manifestations and asthma may provide evidence of these interventions as an effective adjunct to improve asthma management and control.

Towards better practice in primary health care settings for young people.

ISSUE ADDRESSED: To identify and describe elements of accessibility and other dimensions of quality of primary health care for Australian young people. METHODS: Five sampling frames identified relevant services and programs across New South Wales (NSW) which were then selected using purposive, convenience or snowball sampling. In-depth interviews were conducted with senior staff members, tape-recorded, transcribed, entered into the qualitative software package NUD*IST and coded under seven theme headings. RESULTS: Interviews with 77 services across five sectors in NSW identified seven principles of better practice in youth health. These were: accessibility, evidence-based practice, youth participation, collaboration, professional development, sustainability and evaluation. Accessibility was the principle most frequently addressed and evaluation was the least frequently addressed. Many seemingly effective programs and services had been minimally evaluated for impact or outcome related to young people's access or health. CONCLUSIONS: Principles of better practice in promoting or delivering adolescent health care have strong face validity across a range of sectors and service types in a heterogeneous primary health care system. These principles are applied to varying degrees in a vast array of health and health promotion programs. Despite this, there is a clear need for impact and outcome evaluation among the majority of programs.

Chronic kidney disease--management update.

BACKGROUND: Chronic kidney disease (CKD), defined as a glomerular filtration rate less than 60 mL/min/1.73 m2 and/or evidence of kidney damage for a period of at least 3 months, is an increasingly common, serious and under-recognised condition. A recent population study demonstrated that one in every 6 Australian adults has CKD (of which the vast majority are unaware). OBJECTIVE: This article aims to provide timely information to health professionals about how to classify and manage CKD. DISCUSSION: Management of CKD involves regular monitoring of cardiovascular and renal risk factors, identifying and treating common CKD complications, and avoiding medications that may worsen CKD. Early detection and timely appropriate management of CKD (especially with respect to blood pressure control) will substantially reduce kidney failure progression and cardiovascular risk by up to 50%.

Automated reporting of GFR--coming soon to a laboratory near you!

BACKGROUND: Serum creatinine concentration is an unreliable and insensitive marker of chronic kidney disease (CKD). To improve CKD detection, Australasian guidelines have recently recommended that laboratories calculate and report an estimated glomerular filtration rate (eGFR) using the Modification of Diet in Renal Disease (MDRD) formula with every request for serum creatinine concentration. OBJECTIVE: This articles aims to provide timely information to health professionals about how to appropriately interpret and act upon eGFR reports. It also discusses the treatments shown to reduce renal and cardiovascular risk in CKD patients, and the indications for nephrologist referral. DISCUSSION: The accuracy and precision of eGFRs are reasonable in most adults in whom calculated values are ENTITY lt 60 mL/min/1.73 m2. However, eGFRs should be interpreted with caution in some settings (particularly patients with eGFRs ENTITY gt 60 mL/min/1.73 m2 and children). Automatic laboratory reporting of eGFR will enhance early detection of CKD, allow the timely institution of appropriate reno- and cardio-protective therapies, and better inform decisions regarding the prescription of renally excreted medications.

External clinical teaching visits in the regionalised environment.

BACKGROUND: The external clinical teaching (ECT) visit remains integral to the programs of all regional providers of the Australian General Practice Training (AGPT) program. METHOD: All 22 regional training providers (RTPs) were contacted by mail and telephone regarding their use of ECT visits. RESULTS: Responses were received from 17 of the 22 RTPs. There was considerable variation in approach to visitor training, reporting formats, provision of manuals, and the stated purpose of the visits. DISCUSSION: This study has provided a clearer picture of how ECT visits are functioning in the regionalised environment. There remains considerable variation in the use of these visits in Australian general practice training. New national guidelines promoting educational quality in ECT visits and protecting the diversity of regionalisation should be implemented. The use of these visits for performance appraisal needs further discussion.

Access to health care among Australian adolescents young people's perspectives and their sociodemographic distribution.

PURPOSE: To identify the health concerns for which adolescent residents in New South Wales, Australia, do not receive health care, and the associated factors, including their sociodemographic distribution. METHODS: Purposive sampling was used to recruit school students who were stratified by gender and age (12-14, 14-16 and 16-17 years), from schools stratified by socioeconomic status and urban/rural location. Out-of-school young people were recruited through youth health services. Qualitative methods were used to collect and analyze data. RESULTS: Eighty-one focus groups were conducted. Most young people defined health solely in terms of their physical well-being, but still identified a broad range of situations, conditions, or behaviors which they believed might affect their health. One-third of females and two-thirds of males said they would not seek help for their health concerns, and when they did, were most likely to seek help from family, friends, or others they trusted. When professional help was sought, young people again preferred someone they knew and trusted. The three groups of barriers to accessing health care were: concerns about confidentiality, knowledge of services and discomfort in disclosing health concerns, and accessibility and characteristics of services. Factors related to use of health care services were associated with age, gender, and location, but rarely with socioeconomic status. CONCLUSIONS: The majority of these young people in New South Wales (particularly males) do not seek health care despite identifying a broad range of issues that affect their health.

Access to primary health care for Australian adolescents: how congruent are the perspectives of health service providers and young people, and does it matter?

OBJECTIVE: To explore the extent of congruence between the views of service providers and young people (on adolescents' health concerns, barriers to accessing health services and ideal service model) in order to improve and increase the appropriateness, quality and usage of primary health care services. METHODS: A qualitative data collection technique was used. During 2001/02, focus groups were conducted in urban and rural locations with adolescents (in and out of mainstream education), general practitioners, community health staff and youth health workers. RESULTS: Service providers and young people identified a similar range of health concerns for young people, with young people adding additional issues of great importance to them that service providers felt were not in their 'domain of treatment'. There was reasonable congruence in regard to 'ideal service model' with some differences relating to methods of information delivery. However, for 'barriers to accessing services' there were major discrepancies. CONCLUSIONS: While there is some common understanding between young people and service providers on certain aspects of health services, there are clearly areas where perceptions differ. This discrepancy matters because it may adversely affect the quality of provider-adolescent interaction and the willingness of adolescents to access services. IMPLICATIONS: To deliver optimal health services to young people, the differences in understanding regarding services need to be addressed. Strategies could include promotion to, and encouragement of, young people to seek help, continuing professional education of providers and changes in remuneration policies.

Access to primary health care for Australian young people: service provider perspectives.

BACKGROUND: To adequately address the complex health needs of young people, their access to services, and the quality of services received, must be improved. AIMS: To explore the barriers to service provision for young people and to identify the training needs of primary healthcare service providers in New South Wales (NSW), Australia. DESIGN OF STUDY: A cross-sectional, qualitative study of the perspectives of a range of health service providers. SETTING: A range of primary healthcare organisations across NSW. METHODS: Samples of general practitioners (GPs), youth health workers, youth health coordinators, and community health centre staff were drawn from urban and rural clusters across NSW. Focus groups and interviews were used to identify barriers to service provision and the training needs of service providers. Data were tape recorded, transcribed, and analysed. RESULTS: Barriers to service provision among GPs and community health centre staff included inadequate time, flexibility, skills, and confidence in working with young people, and poor linkages with other relevant services. Training needs included better knowledge of and skills in adolescent health requirements, working with adolescents, and working with other services. Barriers to service provision for youth health workers and coordinators included lack of financial resources and infrastructure. There were few linkages between groups of service providers. CONCLUSION: Models of service provision that allow stronger linkages between service providers, sufficient time for consultation with young people, adequate training and support of health professionals, and flexibility of service provision, including outreach, should be explored and evaluated.
