Comparison of public health specialty training in Australia and England.

OBJECTIVES: The objective of the study is to explore common challenges and distinct features of specialty public health training in Australia and England, given similarities in public health issues faced, shared histories and common political structures. STUDY DESIGN: The study design used in the study is a document review. METHODS: Using current curricula, along with other publicly available documents, we reviewed organisational, selection and content elements of public health specialty training in these two countries. RESULTS: In both countries, specialist public health training is coordinated and accredited through Faculties of Public Health housed within Royal Colleges of Physicians. However, eligibility, recruitment to training and funding routes differ. In England, entrants are accepted from a range of backgrounds including medicine, whereas only medical doctors are eligible in Australia. England has a national, annual recruitment process; Australia does not and has a less structured training path. In Australia, specialty advanced training is three years (excluding a Master's in Public Health [MPH]), whereas in England, training is generally five years (including an MPH). Curricula cover broadly common domains of public health practice although there are differences. Methods to assess readiness for consultant practice differ. CONCLUSIONS: Fostering an understanding of the specialist role of public health professionals in different countries establishes routes to share learning, encourage greater collaboration and creates opportunities for benchmarking.

Retention time for corticosteroid-sparing systemic immunosuppressive agents in patients with inflammatory eye disease.

BACKGROUND: Multiple immunosuppressive drugs have been used to manage inflammatory eye disease when control cannot be achieved by corticosteroid alone. However, although clinical studies support the effectiveness of most of these agents, comparative studies have not been undertaken. Retention time, a measure of the duration of treatment with any given drug, is a crude indicator of drug effectiveness and tolerability that facilitates such a comparison. The retention time was compared for corticosteroid-sparing immunosuppressive agents in patients attending our tertiary referral inflammatory eye disease clinic. METHODS: The clinical records of all patients attending an inflammatory eye disease clinic at the Casey Eye Institute over a 1-year period (2003) were reviewed. From these records, we collected the following clinical data: age; sex; ocular diagnosis; and use of steroid-sparing systemic immunosuppression, including drugs, duration of treatment and, if ceased, reasons for cessation. Cox regression analysis, adjusted for clustering, was used to compare other drugs against methotrexate. RESULTS: 107 of 302 (35%) patients seen at the inflammatory eye disease clinic in 2003 had a total of 193 current or past prescriptions for systemic steroid-sparing immunosuppressive agents. The treated group, most of whom had uveitis, included 32 men and 75 women, aged 5-86 years. Most commonly prescribed were methotrexate (66 uses, 34%), ciclosporin (37 uses, 19%), azathioprine (26 uses, 13%), mycophenolate mofetil (22 uses, 11%) and cyclophosphamide (15 uses, 8%). Patients were retained significantly less on ciclosporin (p = 0.004), azathioprine (p = 0.04), mycophenolate mofetil (p = 0.04) and cyclophosphamide (p<0.001) compared with methotrexate. Reasons for cessation included adverse events, lack of effectiveness, success or remission, cost and desire for fertility. CONCLUSIONS: In patients with inflammatory eye disease, methotrexate may offer a superior combination of effectiveness and tolerability over other commonly used corticosteroid-sparing immunosuppressive agents. In this study, there was a twofold risk of not being retained on azathioprine, mycophenolate mofetil and ciclosporin and a fourfold risk of not being retained on cyclophosphamide compared with methotrexate.

Association between parental perception of children's vulnerability to illness and management of children's asthma.

This study examined the relationship between asthma management strategies used by parents and parental perception of children's vulnerability to illness. Home interviews were conducted with 101 parents of children previously hospitalized with asthma. The child vulnerability scale (CVS) was employed to assess parents' perception of their children's vulnerability to illness. The asthma severity index (ASI) was used to measure the frequency and intensity of asthma symptoms experienced by children in the preceding 12 months. Five markers of parental asthma management were assessed: (i) school absences; (ii) visits to the general practitioner (GP); (iii) visits to the emergency room (ER); (iv) hospitalizations; and (v) whether children are using a regular preventer. After controlling for the frequency and intensity of children's asthma symptoms, parents who perceived that their children were more vulnerable to medical illness were significantly more likely to keep their children home from school (P = 0.01), were more likely to take their children to the GP for acute asthma care (P = 0.02), and were more likely to be giving their children regular preventer medication (P = 0.02). In contrast, the use of tertiary pediatric care services was not significantly associated with parental perceptions of their children's vulnerability. The results suggest that parental attitudes and beliefs about the vulnerability of their children to illness were associated with greater use of GP services by parents and more frequent school absences for children. The use of hospital services by parents appeared to be more strongly associated with the actual level of children's asthma symptoms than their vulnerability to illness.

Dietetic Practices in the Management of Childhood Obesity in Malaysia

Introduction: Dietitians play an essential role in the management of childhood obesity and consistency in dietetic practices is required to ensure the effectiveness of treatment. This study assessed dietitians’ current practices in the management of childhood obesity, compared the practices with nutrition practice guidelines used by dietitians in other countries and identified practice components for the development of nutrition practice guidelines for the management of childhood obesity in Malaysia. Methods: A cross-sectional study was conducted among 40 dietitians in 16 Ministry of Health hospitals and three teaching hospitals. Information on current dietetic practices in the management of childhood obesity was obtained through a mailed survey questionnaire. The practices included nutritional assessment, determination of energy requirement, dietary prescription and physical activity modification. Emails were sent to 31 dietetic associations in other countries to obtain information on practice guidelines used by dietitians. Results: Frequently used dietary intervention and physical activity modification approaches were high fibre diet (65%), low fat diet (40%), reduction of sedentary pursuits and screen times (67.5%) and an increase in duration of current physical activities (60%). In comparison to other dietetic practice guidelines, the current dietetic practices in Malaysia do not usually include waist circumference, biochemical and blood pressure data. However, similar to other guidelines, the current dietetic practices included low dietary fat, high fibre diet, decreased sedentary activity and increased physical activity level. Conclusions: The dietetic practices in the management of childhood obesity in Malaysia are diverse. A comprehensive nutrition practice guideline for management of childhood obesity is urgently needed for standardisation of dietetic practices in Malaysia.

Sclerotherapy for leg telangiectasia--a blinded comparative trial of polidocanol and hypertonic saline.

BACKGROUND: Hypertonic saline (HS) and polidocanol (POL) have been in use around the world for sclerotherapy of telangiectasia for many years. However, despite numerous articles in the literature extolling the virtues of their individual use, few studies scientifically compare their relative efficacies. OBJECTIVE: To compare, in a statistically significant number of female patients, the relative efficacy of hypertonic saline and polidocanol as sclerosants of leg telangiectasia and reticular feeding veins, using each patient as her own control. METHODS: Eighty-one women with roughly matching leg telangiecasia were treated with sclerotherapy. One leg was injected with 20% saline/2% lignocaine, the other with 1% polidocanol, with the patients blinded as to the sclerosant used for each leg. Assessment of percent reduction of vessels, and the complications of matting and hemosiderin staining was conducted at 2 months by 3 methods: the patient's satisfaction, the treating physician's evaluation, and blinded assessment of before and after photographs. RESULTS: There was no statistically significant difference between HS and POL treated legs when assessed clinically or photographically. However, POL caused more staining and matting, and despite patients finding HS more painful at injection, patient satisfaction at follow-up was higher with the HS treated leg. CONCLUSION: 20% HS and 1% POL have equal efficacy in sclerosing leg telangiectasia and reticular feeding veins. POL causes more adverse sequelae, although these may be related to the solution concentration.

Retinopathy of prematurity in a south Australian neonatal intensive care unit.

PURPOSE: To establish the incidence and severity of retinopathy of prematurity (ROP) in an Australian population of premature infants, and define risk factors for this population. METHODS: A survey of neonates born weighing less than 1501 g and/or with gestational age below 33 weeks, was undertaken at a neonatal intensive care unit in South Australia. RESULTS: ROP was diagnosed in 16.0% of the 94 neonates who were screened until retinal vascularisation was complete. Threshold disease occurred in 4.2%. Logistic regression identified three significant risk factors for the development of ROP: days of mechanical ventilation, multiple birth and female sex. CONCLUSIONS: The incidence of ROP was relatively low when compared with figures recently published for two large populations studied in the United States and England. This difference was due to a lower incidence of mild forms of the disease. Days of mechanical ventilation, multiple birth and female sex were independently predictive of the occurrence of ROP. As small numbers of infants with ROP are managed at individual Australian centres each year, a national ROP register is recommended to facilitate the study of the disease in this country.

The relationship between the quality of life of children with asthma and family functioning.

The quality of life of 84 children with asthma, aged 7-12 years, and their family functioning was assessed using standard questionnaires. A significant relationship was found between children's reports of their quality of life and several key dimensions of family functioning. The results suggest that independent of their frequency, the extent to which asthma symptoms upset and bother children varies depending on the level of the functioning of the children's families. Treatment approaches designed to improve family functioning may reduce the extent to which children are bothered by their asthma symptoms and thus improve their quality of life.

An inter-university community child health clinical placement programme for medical students.

BACKGROUND: Inpatient teaching no longer reflects the full spectrum of paediatric practice and community-based programmes with clearly defined aims and evaluation of learning are becoming increasingly important. Competition for community resources poses threats to the delivery of effective community child health learning programmes by individual medical schools. OBJECTIVES: To develop and evaluate a combined inter-university, child-focused, active learning programme in community child health. METHODS: A total of 55 postgraduate-entry medical students from the Flinders University of South Australia and 97 undergraduate-entry University of Adelaide students were placed with 25 community child health agencies and instructed to assess services from a client perspective by tracking one child and family through multiple agency contacts. Following each placement, achievement of specific programme aims was evaluated by students and agency staff using a 7-point Likert scale. RESULTS: Students and agency staff indicated substantial achievement of programme aims. Mean agency ratings were significantly higher than student ratings for three aims: students' experiencing a wider spectrum of health care problems than in teaching hospitals (5.7 +/- 1.5 versus 4.9 +/- 1.6, P < 0.001); the importance of social and environmental factors (5.9 +/- 1.0 versus 5.2 +/- 1.4, P < 0.001), and the importance of coordinating care (6.0 +/- 1.0 versus 5.2 +/- 1.2, P < 0.001). Ratings from undergraduate-entry students differed from those of postgraduate-entry students only with respect to the importance of social and environmental factors (4.8 +/- 1.4 versus 5.7 +/- 1.1, P < 0.001). CONCLUSIONS: The new collaborative Community Child Health Programme substantially achieved learning aims and demonstrated effective integration of postgraduate- and undergraduate-entry medical students from two universities.

The relationship between asthma severity, family functioning and the health-related quality of life of children with asthma.

This study compared the health-related quality of life (HRQL) of 236 children with mild or moderate/severe asthma with that of a large representative sample of children in the general community. The study also examined the relationship between the HRQL of children with asthma and their demographic characteristics, asthma severity and family functioning. Children with asthma had a significantly poorer HRQL than other children in the community. Amongst the children with asthma, parents reported that children living in single-parent families had poorer physical health, mental health and social functioning than children in two-parent families. There was a significant relationship between the mental health of children with asthma and family functioning but no significant relationship between their physical health and family functioning. These findings suggest that the domains comprising the HRQL of children with asthma are related to both disease and non-disease factors. A better understanding of these relationships will facilitate the development of new interventions to help children with asthma.

Improvement in outcome of children with Wilms' tumour in South Australia over the last 30 years.

OBJECTIVE: To evaluate the outcome of children with Wilms' tumour over the last 30 years in South Australia. To compare the outcome of children treated before and after 1982, when standard treatment protocols were introduced. METHODOLOGY: Management approaches, survival rates and side-effects of treatment were identified from case notes. Pathology slides were reviewed to ensure all children were correctly diagnosed with Wilms' tumour. RESULTS: Children treated for Wilms' tumour prior to 1982 had an overall survival rate of 54%. Since 1982 there has been a significant improvement in outcome and the current survival rate is now 85%. Children treated since 1982 have also experienced fewer treatment related side-effects than children treated prior to 1982. CONCLUSIONS: There has been substantial improvement in survival from childhood Wilms' tumour over the past 30 years in South Australia. This is likely to be due to a combination of factors including standardization of treatment, tailoring of treatment to stage and histology, improved perioperative care, enhanced radiological techniques and higher levels of collaboration between relevant specialists.

Health-service use by children with asthma over a 6-month period.

OBJECTIVES: The present study aims to describe the use of health services by children with asthma, and examine disease-specific, parental and sociodemographic variables associated with different levels of health-service utilization. METHODS: Parents of 135 children attending an emergency room (ER) completed questionnaires measuring the children's asthma symptoms, and sociodemographic and psychological variables. Parents were contacted monthly for 6 months to document the number of planned and unplanned visits to hospital and community health-care services for asthma. RESULTS: At least one further unplanned visit to the ER was made by 37% of children, while 62% made at least one unplanned visit to a general practitioner (GP). Fifty-five per cent made planned review visits to a GP, 30% to paediatricians and 5% to hospital clinics. After controlling for the level of asthma symptoms, parental anxiety and parental perceptions of children's vulnerability were associated with unplanned GP visits (P = 0.05 and P = 0.01, respectively); a planned review visit and the child being admitted to hospital for the index attack were associated with unplanned ER visits (P = 0.05 and P = 0.004, respectively). CONCLUSIONS: Children with asthma more frequently attend GP services than hospital services for both planned and unplanned asthma management. Different variables predict the unplanned use of GP and ER services. Understanding these differences is imperative if children and families are to make the most effective use of health services.
