The diabetes health care of Aboriginal people in South Australia (Part 1).

Although type 2 diabetes is a recognised health priority in South Australia, Aboriginal people with diabetes do not utilise the mainstream diabetes health services on a regular basis for health care. This means that Aboriginal clients have the potential to develop diabetes-related problems and, furthermore, are not in a position to make informed decisions about health care issues. This lack of client empowerment is contrary to the goals of contemporary diabetes health care and, as a result, Aboriginal clients suffer the consequences of ineffective management with a compromised lifestyle. To identify how this situation might be improved, a qualitative study funded by Diabetes Australia was undertaken in South Australia. The overall goal was, firstly, to identify the reasons why Aboriginal people with diabetes do not attend mainstream health agencies on a regular basis and secondly, if possible, to improve attendance. Thus, Aboriginal health professionals (n = 43) were recruited from the 8 statistical divisions of South Australia and interviewed about Aboriginal diabetes health care issues. In Part 1 of this series, the research findings indicated the beliefs and attitudes held by clients about diabetes, their lack of knowledge about management issues, their responses to diabetes, the effects of diabetes on their lifestyle and the strategies that diabetes health professionals used to help their clients deal with diabetes health issues. In Part 2 the research findings indicated the importance of the Aboriginal health worker to the successful diabetes management of Aboriginal clients, the constraints that affect the delivery of diabetes health care and the recommendations made by health professionals to improve the standard of diabetes health services.

Virtual center for renal support: technological approach to patient physiological image.

The patient physiological image (PPI) is a novel concept which manages the knowledge of the virtual center for renal support (VCRS), currently being developed by the Biomedical Engineering Group of the University of Seville. PPI is a virtual "replica" of the patient, built by means of a mathematical model, which represents several physiological subsystems of a renal patient. From a technical point of view, PPI is a component-oriented software module based on cutting-edge modeling and simulation technology. This paper provides a methodological and technological approach to the PPI. Computational architecture of PPI-based VCRS is also described. This is a multi-tier and multi-protocol system. Data are managed by several ORDBMS instances. Communications design is based on the virtual private network (VPN) concept. Renal patients have a minimum reliable access to the VCRS through a public switch telephone network--X.25 gateway. Design complies with the universal access requirement, allowing an efficient and inexpensive connection even in rural environments and reducing computational requirements in the patient's remote access unit. VCRS provides support for renal patients' healthcare, increasing the quality and quantity of monitored biomedical signals, predicting events as hypotension or low dialysis dose, assisting further to avoid them by an online therapy modification and easing diagnostic tasks. An online therapy adjustment experiment simulation is presented. Finally, the presented system serves as a computational aid for research in renal physiology. This is achieved by an open and reusable modeling and simulation architecture which allows the interaction among models and data from different scales and computer platforms, and a faster transference of investigation models toward clinical applications.

Evaluation of a project to enhance knowledge of hereditary diseases and management.

During 1992 and 1993, in a designated suburban area of Perth, Western Australia, information on hereditary disease was provided for health professionals and the general community. This information was in the form of posters, pamphlets, postal flyers and return letter cards, a static display, newspaper articles, advertisements and radio broadcasts, and professional seminars. The aim of this project was to evaluate the effectiveness of combined strategies to convey practical information about hereditary disease to the community and health professionals. Multiple measures of response evaluation were used, which included structured questionnaire surveys of health professionals and members of the community before and after the project. In the community surveys, respondents who were female, married, middle aged, and parents, and had a higher level of education or were born in Australia, New Zealand, or the United Kingdom were generally better informed about hereditary diseases. This intervention resulted in only meagre changes in community knowledge about hereditary disease, even though promotional materials were shown to be appropriate. General Practitioners (GPs) and Child Health Nurses (CHNs) were supportive of clinical genetic services and recognised a need for continuation of education in this field. There is a rapidly increasing need for community and health professional comprehension of the applications of the new genetic technology. This project indicates that routine educational and health promotion strategies will not be enough to achieve desired levels of knowledge and attitude change.

[Evaluating the potential of an intervention aimed at promoting oral rehydration therapy (ORT) by educating pharmacy employees].

Diarrhea is a major cause of morbidity and mortality in childhood, and Brazilians rely heavily on pharmacies for the resolution of this and other health problems. To promote the rational use of both pharmaceuticals and oral rehydration therapy (ORT), an intervention study was performed in pharmacies in Southwestern Brazil. Semi-structured interviews showed oral rehydration solution, or ORS (50%), antidiarrheals (39%), trimethoprim-sulfamethoxazole (27%), and yeast (22%) to be the most frequently suggested drugs, whereas questionnaire responses were ORS (75%), trimethoprim-sulfamethoxazole (25%), and yeast (25%), thus revealing that more than one methodology is needed if reliable data are to be obtained. An educational intervention was applied to 86.7% of pharmacies, but acquisition of knowledge on management of diarrhea did not prevent pharmacy workers from suggesting antidiarrheal drugs instead of ORS alone. In order to have pharmacy workers comply with official protocols for episodes of diarrhea, interventions should include regulatory measures on drugs that are contraindicated for children, and the role of pharmacies and pharmacists should be reviewed.

Applying Knowledge Discovery in Databases in public health data set: challenges and concerns.

We are investigating the use of axiomatic design (AD) as a principled approach to the revision of guidelines. AD models guidelines in a modular and hierarchical manner and captures interactions be-tween modules. To test this approach we applied AD to encode segments of three guidelines and their revised versions. Guideline encodings for the original versions were modified to incorporate changes made in the revised documents. The results indicate that AD is a promising approach for guideline modeling.

Problem-based learning in a managed care seminar for all new residents at an academic medical center.

One of the most important challenges in resident education is to train residents how to function in relation to managed care companies and systems so as to enhance the quality, accessibility, and efficiency of health care. Since 1996, The University of Texas Medical Branch in Galveston has presented an annual half-day seminar on managed care to new residents. The format involves training sessions and didactic presentations aimed at small groups (led by faculty physicians and nonphysicians from throughout the medical and managed care establishments). Problem-based learning sessions conducted in these groups focus on topics such as the organization of managed care systems, access, network, admit versus observation, inpatient status, denials, avoidable hospital days, concurrent reviews, gatekeepers, referrals, behavioral health, disease management programs, and financial considerations. Pretests and posttests are given to those participating to gauge the effectiveness of the program. In addition, participants complete evaluation forms that can be used by program coordinators to assess resident satisfaction with the learning format and to determine what improvements can be made in the process. For the 1999 and 2000 seminars, posttest results were significantly higher than pretest results for the new residents who participated in the seminar. Each year, seminar evaluations show that the small-group format is well received. We conclude that the small-group learning format is effective and enjoyable for the residents and their leaders. The format necessitates the training of 30 group leaders to increase their knowledge of managed care systems.

Clinician perceptions of personal safety and confidence to manage inpatient aggression in a forensic psychiatric setting.

Inpatient mental health clinicians need to feel safe in the workplace. They also require confidence in their ability to work with aggressive patients, allowing the provision of therapeutic care while protecting themselves and other patients from psychological and physical harm. The authors initiated this study with the predetermined belief that a comprehensive and integrated organizational approach to inpatient aggression was required to support clinicians and that this approach increased confidence and staff perceptions of personal safety. To assess perceptions of personal safety and confidence, clinicians in a forensic psychiatric hospital were surveyed using an adapted version of the Confidence in Coping With Patient Aggression Instrument. In this study clinicians reported the hospital as safe. They reported confidence in their work with aggressive patients. The factors that most impacted on clinicians' confidence to manage aggression were colleagues' knowledge, experience and skill, management of aggression training, use of prevention and intervention strategies, teamwork and the staff profile. These results are considered with reference to an expanding literature on inpatient aggression. It is concluded that organizational resources, policies and frameworks support clinician perceptions of safety and confidence to manage inpatient aggression. However, how these are valued by clinicians and translated into practice at unit level needs ongoing attention.

Building an allergens ontology and maintaining it using machine learning techniques.

Ontologies are widely used for formalizing and organizing the knowledge of a particular domain of interest. This facilitates knowledge sharing and re-use by both people and systems. Ontologies are becoming increasingly important in the biomedical domain since they enable knowledge sharing in a formal, homogeneous and unambiguous way. Knowledge in a rapidly growing field such as biomedicine is usually evolving and therefore an ontology maintenance process is required to keep ontological knowledge up-to-date. This work presents our methodology for building a formally defined ontology, maintaining it exploiting machine learning techniques and domain specific corpora, and evaluating it using a well-defined experimental setting. The application of this methodology in the allergen domain is then discussed in detail presenting the ontology built, the specific techniques used and the evaluation settings.

"Stingers" in adolescent athletes.

Brachial plexus injuries commonly occur in athletes participating in contact sports. The incidence of transitory brachial plexus injury is approximately 30% to 50% over the course of a high school, college, or professional football player's career. These injuries are called "stingers" or "burners" because of the associated tingling that occurs in the upper extremity after the injury. Brachial plexus injuries are poorly understood and sometimes are difficult to manage. Appropriate knowledge and understanding of these injuries along with prompt recognition, diagnosis, and treatment are essential for optimal care of the injured athlete and for the athlete's timely return to play. Most injuries occur by one of three mechanisms: traction, compression, or hyperextension and compression. Injuries are clinically classified as neurapraxia, neurapraxia/axonotmesis, and neurotmesis according to their symptomatology and the pattern of symptom resolution. Most injuries are either a neurapraxia or a neurapraxia/axonotmesis. Most athletes recover completely and can return to play after they are asymptomatic and have regained full sensation, strength, and range of motion. Protective equipment has been introduced to decrease the occurrence of stingers. Education of the athlete, the family, and coaches is important to help them to understand and to assist in managing these injuries.

Minor illness education for parents of young children.

BACKGROUND: A number of previous studies on minor illness have concentrated on nurse-led clinics and the role of nurse practitioners. This study examines the effect of a minor illness education programme which aimed to increase parents' confidence and knowledge in managing childhood illnesses. AIM: The primary aim of this study was to evaluate the effectiveness of a home visit and booklet in providing education to parents about minor infant illnesses. DESIGN: A randomized controlled trial was conducted. The intervention involved a home visit to discuss parents' concerns and provide advice and information, and a booklet advising parents what to do and when to consult about infant illnesses. METHOD: A total of 120 parents of 6 week old babies were identified over a 6 month period, using health visitors' caseloads, and randomized to an intervention group (60), that received a visit and a booklet, or a control group (60) that received standard care. Groups were compared on entry to the study and at 7 months, in terms of parental knowledge and confidence about childhood illnesses, the intended use of home care activities, intention to consult professionals and actual use of health services. Data were collected by self-completed questionnaire and case note review. FINDINGS: The educational intervention resulted in a reduction in visits to the child health clinic but had little effect on use of other services. Parents in the intervention group showed a general trend towards greater certainty about the home care options they would choose, and a reduction in intention to consult a doctor. However, they also indicated a feeling of reduced confidence and knowledge. CONCLUSION: The trial showed no effect on use of services but did demonstrate reduction in parents' intentions to consult a doctor, which appeared to be because of increased certainty about home care. However, it is of concern that they indicated feeling less confident and knowledgeable. It is not possible to clarify whether this represented anxiety that was constructive, enhancing decision-making or was destructive. Further work into the role of education in parental decision-making, anxiety levels and enhancement of confidence is required.

Reengineering knowledge and skills: essential for nurse managers.

Nurse managers of this decade and beyond face a very different set of performance expectations than they did only 10 years ago. Although many of the previously acquired skills remain useful, there are new skills to be assimilated to enhance organizational and clinical effectiveness. Reengineering is a valuable knowledge tool that nurse managers can put to use across health care settings. Nurse managers become process-owners, and as such can effect substantive positive change within their organizations.

Nurses in private nursing homes: a study of their knowledge and attitudes to pain management in palliative care.

Nurses working in private nursing homes may not have the same degree of access to support and education in palliative care as nurses in NHS 'care of the elderly' wards. A study was conducted comparing two groups of nurses working in these two environments in one health district. Twenty-four nurses underwent semistructured interviews focusing on pain management. Both groups showed equal enthusiasm for their work with elderly patients. However, those from the care of the elderly wards were able to offer many more treatment strategies to relieve pain than their colleagues from the private nursing homes. The study uncovered a sense of isolation and a lack of postbasic education opportunities for nurses outside the NHS. If this small local study reflects a national trend, then there are major implications for the educational activities of palliative care teams.

Efficacy and cost-effectiveness of environmental management for malaria control.

Roll back malaria (RBM) aims at halving the current burden of the disease by the year 2010. The focus is on sub-Saharan Africa, and it is proposed to implement efficacious and cost-effective control strategies. But the evidence base of such information is scarce, and a notable missing element is the discussion of the potential of environmental management. We reviewed the literature and identified multiple malaria control programmes that incorporated environmental management as the central feature. Prominent among them are programmes launched in 1929 and implemented for two decades at copper mining communities in Zambia. The full package of control measures consisted of vegetation clearance, modification of river boundaries, draining swamps, oil application to open water bodies and house screening. Part of the population also was given quinine and was sleeping under mosquito nets. Monthly malaria incidence rates and vector densities were used for surveillance and adaptive tuning of the environmental management strategies to achieve a high level of performance. Within 3-5 years, malaria-related mortality, morbidity and incidence rates were reduced by 70-95%. Over the entire 20 years of implementation, the programme had averted an estimated 4173 deaths and 161,205 malaria attacks. The estimated costs per death and malaria attack averted were US$ 858 and US$ 22.20, respectively. Over the initial 3-5 years start-up period, analogous to the short-duration of cost-effectiveness analyses of current studies, we estimated that the costs per disability adjusted life year (DALY) averted were US$ 524-591. However, the strategy has a track record of becoming cost-effective in the longer term, as maintenance costs were much lower: US$ 22-92 per DALY averted. In view of fewer adverse ecological effects, increased sustainability and better uses of local resources and knowledge, environmental management--integrated with pharmacological, insecticidal and bednet interventions--could substantially increase the chances of rolling back malaria.

Influencing nurses' knowledge, attitudes, and practice in cancer pain management.

The purpose of this study was to explore the effects of an education intervention on nurses' knowledge, attitudes, and practice in pain assessment and management over 3 months. The education intervention program was designed to change knowledge and influence the attitudes of registered nurses through a values clarification process using a conceptual framework based on a theory of reeducation. Participants in this descriptive, exploratory study were 53 nurses from six oncology units. Data were collected on their knowledge, attitudes, documentation practices, and analgesic choices in defined patient situations. The intervention was effective in changing the knowledge, attitudes, and behaviors of nurses in the study, but the effect was not maintained over time. Study findings suggest that further educational and organizational support is needed for effective practice in pain assessment and management. Further research should explore education programs that will maintain new knowledge over time. In addition, assessment of the effect that new knowledge has on the achievement of improved pain relief for patients should be explored in the future.

Information management: considering adolescents' regulation of parental knowledge.

Employing Goffman's [(1959). The presentation of self in everyday life. New York: Doubleday and Company] notion of impression management, adolescents' conveyance of information about their whereabouts and activities to parents was assessed employing two methodologies. First, a two-wave panel design with a sample of 121 adolescents was used to test a model of information management incorporating two forms of information regulation (lying and willingness to disclose), adolescents' perception of their parents' knowledge about their activities, and adolescent misconduct. Path analysis was used to examine the model for two forms of misconduct as outcomes: substance use and antisocial behaviours. Fit indices indicate the path models were all good fits to the data. Second, 96 participants' responses to semi-structured questions were analyzed using a qualitative analytic technique. Findings reveal adolescents withhold or divulge information in coordination with their parents, employ impression management techniques, and try to balance safety issues with preservation of the parent-adolescent relationship.

Patient accounting systems: needs and capabilities.

In the first article of this series, it was stated that most finance executives are not very satisfied with the performance of their current patient accounting systems. What steps can a patient accounting system planner take to help ensure the system selected will garner high ratings from managers and users? Two primarily steps need to be taken. First, the planner needs to perform a thorough evaluation of both near- and long-term patient accounting requirements. He should determine which features and functions are most critical and ensure they are incorporated as selection criteria. The planner should also incorporate institutional planning into that process, such as planned expansion of facilities or services, to ensure that the system selected has the growth potential, interfacing capabilities, and flexibility to respond to the changing environment. Then, once system needs are fully charted, the planner should educate himself about the range of patient accounting system solutions available. The data show that most financial managers lack knowledge about most of the major patient accounting system vendors in the marketplace. Once vendors that offer systems that seemingly could meet needs are identified, the wise system planner will also want to obtain information from users about those vendors, to determine whether the systems perform as described and whether the vendor has been responsive to the needs of its customers. This step is a particularly important part of the planning process, because the data also show that users of some systems are significantly more satisfied than users of other patient accounting systems.

A poultry-processing model for quantitative microbiological risk assessment.

A poultry-processing model for a quantitative microbiological risk assessment (QMRA) of campylobacter is presented, which can also be applied to other QMRAs involving poultry processing. The same basic model is applied in each consecutive stage of industrial processing. It describes the effects of inactivation and removal of the bacteria, and the dynamics of cross-contamination in terms of the transfer of campylobacter from the intestines to the carcass surface and the environment, from the carcasses to the environment, and from the environment to the carcasses. From the model it can be derived that, in general, the effect of inactivation and removal is dominant for those carcasses with high initial bacterial loads, and cross-contamination is dominant for those with low initial levels. In other QMRA poultry-processing models, the input-output relationship between the numbers of bacteria on the carcasses is usually assumed to be linear on a logarithmic scale. By including some basic mechanistics, it is shown that this may not be realistic. As nonlinear behavior may affect the predicted effects of risk mitigations; this finding is relevant for risk management. Good knowledge of the variability of bacterial loads on poultry entering the process is important. The common practice in microbiology to only present geometric mean of bacterial counts is insufficient: arithmetic mean are more suitable, in particular, to describe the effect of cross-contamination. The effects of logistic slaughter (scheduled processing) as a risk mitigation strategy are predicted to be small. Some additional complications in applying microbiological data obtained in processing plants are discussed.
