Responding to our customers' needs: modifications to assessment in Obstetrics and Gynaecology over 20 years

Background and Objectives: This paper reports on historical changes in assessment culminating in the experience of one discipline with negotiated student feedback that has helped design and modify assessment to cater for the requirements of both students and teachers. The standard of assessment required to pass Obstetrics and Gynaecology in the four year graduate entry program in the School of Medicine at The University of Queensland, Brisbane, Australia has become less formalised and more collaborative. Changes in assessment in this discipline over the last 20 years reflect the development of an understanding of the educational principles associated with adult teaching and learning. Assessment has evolved from being teacher focussed, with questionable reliability, validity, and emphasis on outcomes, to being focussed on learning and the student. Multiplechoice examinations, combined with a collaborative approach to the reliability and validity of questions and answers and a debrief or feedback session have been found to provide an assessment format that is art acceptable measure oflearning for both teachers and students. Changes in assessment reflect a collaborative process between teachers and students based on principles of adult learning and involving negotiated student feedback. Our experience with this form of negotiated outcome for assessment is presented together with suggestions for improvement and is contrasted with assessment methods used in this department over the last 20 years. Change and refinement will continue as medical programs strive to meet the learning needs of students and assessment outcomes that are acceptable to its teachers.

Change in physiotherapy management of children with cystic fibrosis in a large urban hospital

A retrospective audit was conducted in 1998 and 2000 to review the physiotherapy management of hospitalized children with cystic fibrosis (CF) at the Brisbane Royal Children's Hospital (RCH). The objective was to detect and explore possible changes in patient management in this time period and investigate whether these changes reflected changes in the current theory of CF management. All children over two years of age with CF admitted during 1998 and 2000 with pulmonary manifestation and who satisfied set criteria were included (n = 249). Relative frequency of each of six treatment modalities used were examined on two occasions, revealing some degree of change in practice reflecting the changes in current theory. There was a significant decrease in the frequency of usage of postural drainage with head-down tilt (p < 0.001), and autogenic drainage (p < 0.001) between 1998 and 2000. Modified postural drainage without head-down tilt (p < 0.001), and positive expiratory pressure devices (p < 0.001) were used more frequently in 2000 (p < 0.001). No significant changes were identified in the use of Flutter VRP1 (p = 0.145) and exercise (p = 0.763). No significant differences were found in population demographics or occurrence of concomitant factors that may influence patient management.

Influence of the 23 October 2002 dust storm on the air quality of four Australian cities

Widespread drought and record maximum temperatures in eastern Australia produced a large dust storm on 23 October, 2002 which traversed a large proportion of eastern Australia and engulfed communities along a 2000 km stretch of coastline from south of Sydney ( NSW) to north of Mackay ( Queensland). This event provided an opportunity for a study of the impacts of rural dust upon the air quality of four Australian cities. A simple model is used to predict dust concentrations, dust deposition rates and particle size characteristics of the airborne dust in the cities. The total dust load of the plume was 3.35 to 4.85 million tones, and assuming a ( conservative) plume height of 1500 m, 62 - 90% of this dust load was deposited in-transit to the coast. It is conservatively estimated that 3.5, 12.0, 2.1 and 1.7 kilotonnes of dust were deposited during the event in Sydney, Brisbane, Gladstone and Mackay, respectively. In the South East Queensland region, this deposition is equivalent to 40% of the total annual TSP emissions for the region. The event increased TSP, PM10 and PM2.5 concentrations and reduced the visibility beyond the health and amenity guidelines in the four cities. For example, the 24-h average PM10 concentrations in Brisbane and Mackay, were 161 and 475 mu g m(-3) respectively, compared with the Australian national ambient air quality standard of 50 mu g m(-3). The 24-h average PM2.5 concentration in Brisbane was 42 mu g m(-3), compared with the national advisory standard of 25 mu g m(-3). These rural dusts significantly increased PM10/TSP ratios and decreased PM2.5/PM10 ratios, indicating that most of the particles were between PM2.5 and PM10.

Wireless telemedicine for the delivery of specialist paediatric services to the bedside

A mobile interactive online health system was used to conduct virtual ward rounds at a regional hospital which had no specialist paediatrician. The system was wireless, which allowed telepaediatric services to be delivered direct to the bedside. Between December 2004 and May 2005, 43 virtual ward rounds were coordinated between specialists based in Brisbane and local staff at the Gladstone Hospital. Eighty-six consultations were provided for 64 patients. The most common conditions included asthma (27%), chest infections (12%), gastroenteritis (10%) and urinary tract infections (10%). In the majority of cases, there were partial (67%) or complete changes (11%) in the clinical management of patients. Specialist services were offered by a team of 13 clinicians at the Royal Children's Hospital: 10 general paediatricians, two physiotherapists and one registered nurse. Feedback from all consultants involved in the service and local staff in Gladstone was extremely positive. In 43 videoconference calls there were three technical problems, probably due to an intermittent mains power supply at the regional hospital. There appears to be potential for other rural and regional hospitals to adopt this model of service delivery.

Delivery of child development services by videoconferencing: a review of four years' experience in Queensland

In 2001 the Child Development Unit (CDU) in Brisbane piloted a series of monthly multidisciplinary case discussions via videoconference in the area of child development. During 2001 two sessions were provided; during 2004 there were 40. The substantial growth in 2004 was due to the expansion of child development services to include special interest group meetings and multipoint case conference meetings. In 2004, a total of 49 h of videoconferencing was conducted. The average session length was 75 min. Education and training sessions were delivered to 32 hospitals and health centres in Queensland and northern New South Wales. The maximum number of sites involved during a single videoconference was 25. The average number of attendees for each videoconference was five per site, including allied health staff, nurses and paediatricians. The delivery of child development services via videoconference has been shown to be useful in Queensland, especially for allied health staff working in regional and remote areas. The growth of the programme indicates its acceptance as a mainstream child development service in Queensland.

Interactions among smoking, obesity, and symptoms of acid reflux in Barrett's esophagus

Background: Barrett's esophagus, a metaplastic precursor to esophageal adenocarcinoma, is becoming increasingly prevalent in many populations. Clinical studies suggest acid reflux causes Barrett's esophagus; however, no population-based estimates of risk have been reported, and the role of other health factors in modifying risk is unclear. Methods: We conducted a population-based case-control study in Brisbane, Australia. Cases were 167 patients with histologically confirmed Barrett's esophagus diagnosed between February and December 2003. Age-matched and sex-matched controls (n = 261) were randomly selected from a population register. Data on exposure to self-reported symptoms of acid reflux, smoking, obesity, and other factors were collected through self-completed questionnaires followed by telephone interview. Risks of Barrett's esophagus and Barrett's esophagus with dysplasia associated with these exposures were estimated by the odds ratio (OR) and 95% confidence interval (95% Cl), both crude and adjusted for other factors. Results: Self-reported weekly episodes of acid reflux were associated with greatly increased risks of Barrett's esophagus (adjusted OR, 29.7; 95% CI, 12.2-72.6) and Barrett's esophagus with dysplasia (OR, 59.7; 95% CI, 18.5-193). Smoking was also associated with risk of Barrett's esophagus. We found evidence of interactions between symptoms of acid reflux and smoking and obesity. Obese people with self-reported symptoms of acid reflux had markedly higher risks of Barrett's esophagus (OR, 34.4; 95% CI, 6.3-188) than people with reflux alone (OR, 9.3; 95% CI, 1.4-62.2) or obesity alone (OR, 0.7,95% CI, 0.2-2.4). Similarly, those reporting both acid reflux symptoms and smoking were at substantially higher risks of Barrett's esophagus (OR, 51.4; 95% CI, 14.1-188) than those reporting acid reflux or smoking alone. Conclusions: Although history of symptoms of acid reflux is the principle factor associated with Barrett's esophagus, risks are substantially increased by obesity and smoking.

Won't pay or can't pay? Exploring the use of fines as a sentencing alternative for public nuisance type offences in Queensland

The complex relationship between marginalized people, 'public nuisance type offences' and fines law is explored. Court observation research conducted in Brisbane is reported which suggests that indigent people are more likely than others to appear before the court on charges related to public space offences, and that they are just as likely as others to receive a fine in response to their offending behaviour despite the legislative provisions aimed at avoiding this

A visiting occupational therapy service to indigenous children in school: Results of a pilot project

The need for additional support for Indigenous children at school is well documented. Occupational therapists are well positioned to form part of this support. However, many occupational therapists report that Indigenous families do not access their services and when they do, the occupational therapist feels uncertain about how best to meet their needs. This article documents a pilot project which delivered occupational therapy services within several schools and preschools in Brisbane which had significant numbers of Indigenous students. The project was evaluated using a qualitative methodology and included focus groups and interviews with teachers and parents. The results indicated that in general the service provided valuable support to students, teachers and parents. In particular, providing the service within the school context was seen as critical to its success. Suggestions for improvements in future support services are also provided.

Piloting the feasibility and effectiveness of print- and telephone-mediated interventions for promoting the adoption of physical activity in Australian adults

This study examined the feasibility and effectiveness for increasing physical activity of a print-based intervention, and a print- plus telephone-mediated intervention among mid-life and older Australian adults. A randomised controlled trial study design was used. In mid-2002, 66 adults (18 men, 48 women) aged 45-78 years, who identified themselves as under-active, were recruited through advertisements and word-of-mouth at two sites (Melbourne and Brisbane), and randomised to either the print or print-plus-telephone mediated intervention group. Participants in both groups attended an initial briefing session, and over the 12-week intervention period received an instructional newsletter and use of a pedometer (both groups), and individualised telephone calls (print- plus-telephone group only). Self-reported physical activity data were collected at baseline, 12 and 16 weeks. Measures of self-reported global physical activity, moderate-vigorous intensity activity and walking all showed increases between baseline and 12 weeks for both intervention groups. These increases were generally maintained by 16 weeks, although participants in the print-plus-telephone group maintained slightly higher levels of global reported activity and walking (by approximately 30 mins/wk) than those in the print group. These interventions show potential for promoting initial increases in physical activity among mid-life and older Australian adults, and should be evaluated across more extended time periods.

Association of public support for survival of wildlife species with their likeability

We surveyed 204 individuals from the general public in Brisbane, Australia, to ascertain the extent to which they liked or disliked 24 species of wildlife (belonging to three classes: mammals, birds and reptiles) present in tropical Australia. We calculated likeability indices for each species. We also asked respondents if they favored the survival of each of these species, and were able to calculate the percentage of respondents favoring survival of each. Using linear regression analysis, we could relate the percentage of respondents favoring survival of each of the species to their indices of likeability. In addition, we compared the mean likeability of species in the three classes (mammals, birds and reptiles) with the respondents' allocation of funds (hypothetical 1,000 Australian dollars) between conservation of species and a human charity. From this, we were able to assess how important stated likeability is for preferences to conserve species by animal class, and reconsidered the hypothesis in the literature that there is likely to be more public support for the survival of mammals than for birds, and more support for the survival of birds than for reptiles.

Study of the integrated cognitive model of depression among Latin-Americans

Objective: The objective of the present study is to test the validity of the integrated cognitive model (ICM) of depression proposed by Kwon and Oei with a Latin-American sample. The ICM of depression postulates that the interaction between negative life events with dysfunctional attitudes increases the frequency of negative automatic thoughts, which in turns affects the depressive symptomatology of a person. This model was developed for Western Europeans such as Americans and Australians and the validity of this model has not been tested on Latin-Americans. Method: Participants were 101 Latin-American migrants living permanently in Brisbane, including people from Chile, El Salvador, Nicaragua, Argentina and Guatemala. Participants completed the Beck Depression Inventory, the Dysfunctional Attitudes Scale, the Automatic Thoughts Questionnaire and the Life Events Inventory. Alternative or competing models of depression were examined, including the alternative aetiologies model, the linear mediational model and the symptom model. Results: Six models were tested and the results of the structural equation modelling analysis indicated that the symptom model only fits the Latin-American data. Conclusions: Results show that in the Latin-American sample depression symptoms can have an impact on negative cognitions. This finding adds to growing evidence in the literature that the relationship between cognitions and depression is bidirectional, rather than unidirectional from cognitions to symptoms.
