Objective: To explore the range of meanings about the role of support for patients with hepatitis C by examining medical specialists' perceptions. Method: The study employed a qualitative, open-ended interview design and was conducted in four major teaching hospitals in Adelaide, South Australia. Eight participants (three infectious disease physicians, four gastroenterologists, one hepatologist), selected through purposive sampling, were interviewed about general patient support, their role in support provision, the role of non-medical support and their reasons for not using support services. Results: Main themes included a focus on support as information provision and that patient education is best carried out by a medical specialist. The use of support services was defined as the patient's decision. Participants identified four key periods when patients would benefit from support; during diagnosis, failure to meet treatment criteria, during interferon treatment and following treatment failure. Conclusions: It was concluded that while barriers exist to the establishment of partnerships between specialists and other support services, this study has identified clear points at which future partnerships could be established. Implications: A partnership approach to developing support for patients with hepatitis C offers a systematic framework to facilitate the participation of health professionals and the community in an important area of public health.

We aimed to evaluate the effect of the appointment of a dedicated specialist thoracic surgeon on surgical practice for lung cancer previously served by cardio-thoracic surgeons. Outcomes were compared for the 240 patients undergoing surgical resection for lung cancer in two distinct 3-year periods: Group A: 65 patients, 1994-1996 (pre-specialist); Group B: 175 patients, 1997-1999 (post-specialist). The changes implemented resulted in a significant increase in resection rate (from 12.2 to 23.4%, P<0.001), operations in the elderly (over 75 years) and extended resections. There were no significant differences in stage distribution, in-hospital mortality or stage-specific survival after surgery. Lung cancer surgery provided by specialists within a multidisciplinary team resulted in increased surgical resection rates without compromising outcome. Our results strengthen the case for disease-specific specialists in the treatment of lung cancer. © 2004 Published by Elsevier Ireland Ltd.

Introduction The suitability of video conferencing (VC) technology for clinical purposes relevant to geriatric medicine is still being established. This project aimed to determine the validity of the diagnosis of dementia via VC. Methods This was a multisite, noninferiority, prospective cohort study. Patients, aged 50 years and older, referred by their primary care physician for cognitive assessment, were assessed at 4 memory disorder clinics. All patients were assessed independently by 2 specialist physicians. They were allocated one face-to-face (FTF) assessment (Reference standard – usual clinical practice) and an additional assessment (either usual FTF assessment or a VC assessment) on the same day. Each specialist physician had access to the patient chart and the results of a battery of standardized cognitive assessments administered FTF by the clinic nurse. Percentage agreement (P0) and the weighted kappa statistic with linear weight (Kw) were used to assess inter-rater reliability across the 2 study groups on the diagnosis of dementia (cognition normal, impaired, or demented). Results The 205 patients were allocated to group: Videoconference (n = 100) or Standard practice (n = 105); 106 were men. The average age was 76 (SD 9, 51–95) and the average Standardized Mini-Mental State Examination Score was 23.9 (SD 4.7, 9–30). Agreement for the Videoconference group (P0= 0.71; Kw = 0.52; P < .0001) and agreement for the Standard Practice group (P0= 0.70; Kw = 0.50; P < .0001) were both statistically significant (P < .05). The summary kappa statistic of 0.51 (P = .84) indicated that VC was not inferior to FTF assessment. Conclusions Previous studies have shown that preliminary standardized assessment tools can be reliably administered and scored via VC. This study focused on the geriatric assessment component of the interview (interpretation of standardized assessments, taking a history and formulating a diagnosis by medical specialist) and identified high levels of agreement for diagnosing dementia. A model of service incorporating either local or remote administered standardized assessments, and remote specialist assessment, is a reliable process for enabling the diagnosis of dementia for isolated older adults.

BACKGROUND: Frequent illness and injury among workers with high body mass index (BMI) can raise the costs of employee healthcare and reduce workforce maintenance and productivity. These issues are particularly important in vocational settings such as the military, which require good physical health, regular attendance and teamwork to operate efficiently. The purpose of this study was to compare the incidence of injury and illness, absenteeism, productivity, healthcare usage and administrative outcomes among Australian Defence Force personnel with varying BMI. METHODS: Personnel were grouped into cohorts according to the following ranges for (BMI): normal (18.5-24.9 kg/m²; n = 197), overweight (25-29.9 kg/m²; n = 154) and obese (≥30 kg/m²) with restricted body fat (≤28 % for females, ≤24 % for males) (n = 148) and with no restriction on body fat (n = 180). Medical records for each individual were audited retrospectively to record the incidence of injury and illness, absenteeism, productivity, healthcare usage (i.e., consultation with medical specialists, hospital stays, medical investigations, prescriptions) and administrative outcomes (e.g., discharge from service) over one year. These data were then grouped and compared between the cohorts. RESULTS: The prevalence of injury and illness, cost of medical specialist consultations and cost of medical scans were all higher (p <0.05) in both obese cohorts compared with the normal cohort. The estimated productivity losses from restricted work days were also higher (p <0.05) in the obese cohort with no restriction on body fat compared with the normal cohort. Within the obese cohort, the prevalence of injury and illness, healthcare usage and productivity were not significantly greater in the obese cohort with no restriction on body fat compared with the cohort with restricted body fat. The number of restricted work days, the rate of re-classification of Medical Employment Classification and the rate of discharge from service were similar between all four cohorts. CONCLUSIONS: High BMI in the military increases healthcare usage, but does not disrupt workforce maintenance. The greater prevalence of injury and illness, greater healthcare usage and lower productivity in obese Australian Defence Force personnel is not related to higher levels of body fat.

Aim: To develop a set of Australian recommendations for the monitoring and treatment of ankylosing spondylitis (AS) through systematic literature review combined with the opinion of practicing rheumatologists. Methods: A set of eight questions, four in each domain of monitoring and treatment, were formulated by voting and the Delphi method. The results of a systematic literature review addressing each question were presented to the 23 participants of the Australian 3E meeting. All participants were clinical rheumatologists experienced in the daily management of AS. Results: After three rounds of breakout sessions to discuss the findings of the literature review, a set of recommendations was finalized after discussion and voting. The category of evidence and strength of recommendation were determined for each proposal. The level of agreement among participants was excellent (mean 84%, range 64-100%). Conclusions: The 12 recommendations developed from evidence and expert opinion provide guidance for the daily management of AS patients. For most recommendations, we found a paucity of supportive evidence in the literature highlighting the need for additional clinical studies.

Objective: To investigate the association between patients' expectations and the actual use of custom-made orthopaedic shoes. Design: A prospective cohort study with internal comparison. Setting: Twelve orthopaedic shoe companies. Patients: During six months, consecutive patients who were provided with their first ever pair of orthopaedic shoes and aged 16 years or older were recruited. A total of 339 patients with different pathologies were included (response 67%). Mean (SD) age of the patients was 63 (15) years, and 129 patients (38%) were male. Main measures: A practical and reproducible questionnaire, measuring: frequency of use of orthopaedic shoes, patients' expectations and experiences of aspects of the usability of orthopaedic shoes, and communication about patients' expectations. Results: Patients' expectations were not associated with the use of orthopaedic shoes (P-values range: 0.106 to 0.607), but the difference between expectations and experiences was (P-values range: <0.001 to 0.012). The expectations of patients who frequently used their orthopaedic shoes were in concordance with their experiences, whereas the expectations of patients who did not use their orthopaedic shoes were much higher than their experiences. There was no communication of patients' expectations with the medical specialist or orthopaedic shoe technician in 34% and 25% of the patients respectively. Conclusions: In relation to the actual use of orthopaedic shoes, it is crucial that patients' expectations are not much higher than their experiences.

This study investigated long-term use of custom-made orthopedic shoes (OS) at 1.5 years follow-up. In addition, the association between short-term outcomes and long-term use was studied. Patients from a previously published study who did use their first-ever pair of OS 3 months after delivery received another questionnaire after 1.5 years. Patients with different pathologies were included in the study (n = 269, response = 86%). Mean age was 63 ± 14 years, and 38% were male. After 1.5 years, 87% of the patients still used their OS (78% frequently [4-7 days/week] and 90% occasionally [1-3 days/week]) and 13% of the patients had ceased using their OS. Patients who were using their OS frequently after 1.5 years had significantly higher scores for 8 of 10 short-term usability outcomes (p-values ranged from <0.001 to 0.046). The largest differences between users and nonusers were found for scores on the short-term outcomes of OS fit and communication with the medical specialist and shoe technician (effect size range = 0.16 to 0.46). We conclude that patients with worse short-term usability outcomes for their OS are more likely to use their OS only occasionally or not at all at long-term follow-up.

Background: Late preterm infants (LPIs), born at 34 + 0 to 36 + 6 weeks of gestation contribute a significant proportion of all neonatal intensive care (NIC) admissions and are regarded as being at risk of adverse outcomes compared to term-born infants.
Aim: To explore the health outcomes and family functioning of LPIs who required neonatal intensive care, at three years of age.
Study design and subjects: This cohort study included 225 children born late preterm, between 1 January and 31 December 2006 in Northern Ireland. Children admitted for NIC (study group, n = 103) were compared with children who did not require NIC or who required special care only for up to three days (comparison group, n = 122).
Outcome measures
Health outcomes were measured using the Health Status Questionnaire, health service usage by parent report and family functioning using the PedsQL™ Family Impact Module.
Results: LPIs who required NIC revealed similar health outcomes at three years in comparison to those who did not. Despite this, more parents of LPIs who required NIC reported visiting their GP and medical specialists during their child's third year of life. Differences in family functioning were also observed with mothers of LPIs who required NIC reporting, significantly lower levels of social and physical functioning, increased difficulties with communication and increased levels of worry.
Conclusions: LPIs were observed to have similar health outcomes at three years of age regardless of NIC requirement. The increase in GP and medical specialist visits and family functioning difficulties observed among those infants who required NIC merits further investigation.

Contexte : Les médecins spécialistes peuvent participer aux soins ambulatoires des personnes atteintes de maladies chroniques (MCs) et comorbidité comme co-gestionnaire ou consultant selon qu’ils sont responsables ou non du suivi du patient. Il y a un manque d’évidences sur les déterminants et l’impact du type d’implication du médecin spécialiste, ainsi que sur la façon optimale de mesurer la comorbidité pour recueillir ces évidences. Objectifs : 1) déterminer chez les patients atteints de MCs les facteurs associés à la cogestion en spécialité, dont les caractéristiques des organisations de première ligne et la comorbidité; 2) évaluer si le type d’implication du spécialiste influence le recours à l’urgence; 3) identifier et critiquer les méthodes de sélection d’un indice de comorbidité pour la recherche sur l’implication des spécialistes dans le suivi des patients. Méthodologie : 709 adultes (65 +/- 11 ans) atteints de diabète, d’arthrite, de maladie pulmonaire obstructive chronique ou d’insuffisance cardiaque furent recrutés dans 33 cliniques de première ligne. Des enquêtes standardisées ont permis de mesurer les caractéristiques des patients (sociodémographiques, comorbidité et qualité de vie) et des cliniques (modèle, ressources). L’utilisation des services de spécialistes et de l’urgence fut mesurée avec une base de données médico-administratives. Des régressions logistiques multivariées furent utilisées pour modéliser les variables associées à la cogestion et comparer le recours à l’urgence selon le type d’implication du spécialiste. Une revue systématique des études sur l’utilisation des services de spécialistes, ainsi que des revues sur les indices de comorbidité fut réalisée pour identifier les méthodes de sélection d’un indice de comorbidité utilisées et recommandées. Résultats : Le tiers des sujets a utilisé les services de spécialistes, dont 62% pour de la cogestion. La cogestion était associée avec une augmentation de la gravité de la maladie, du niveau d’éducation et du revenu. La cogestion diminuait avec l’âge et la réception de soins dans les cliniques avec infirmière ayant un rôle innovateur. Le recours à l’urgence n’était pas influencé par l’implication du spécialiste, en tant que co-gestionnaire (OR ajusté = 1.06, 95%CI = 0.61-1.85) ou consultant (OR ajusté = 0.97, 95%CI = 0.63-1.50). Le nombre de comorbidités n’était pas associé avec la cogestion, ni l’impact du spécialiste sur le recours à l’urgence. Les revues systématiques ont révélé qu’il n’y avait pas standardisation des procédures recommandées pour sélectionner un indice de comorbidité, mais que 10 critères concernant principalement la justesse et l’applicabilité des instruments de mesure pouvaient être utilisés. Les études sur l’utilisation des services de spécialistes utilisent majoritairement l’indice de Charlson, mais n’en expliquent pas les raisons. Conclusion : L’implication du spécialiste dans le suivi des patients atteints de MCs et de comorbidité pourrait se faire essentiellement à titre de consultant plutôt que de co-gestionnaire. Les organisations avec infirmières ayant un rôle innovateur pourraient réduire le besoin pour la cogestion en spécialité. Une méthode structurée, basée sur des critères standardisés devrait être utilisée pour sélectionner l’indice de comorbidité le plus approprié en recherche sur les services de spécialistes. Les indices incluant la gravité des comorbidités seraient les plus pertinents à utiliser.

Hospitals represent complex and difficult contexts for AEC (architecture, engineering and construction) professionals to engage with due to their functional complexity and diversity of stakeholder interests (i.e. patient, visitor, medical specialist). Hospital designers need to take note of changing NHS policy contexts (e.g. the possible empowerment of general practitioners to shape services), technological advances in medical equipment design and the potential health needs of future generations. It is imperative for hospital designers and architects to align their processes and methodologies (e.g. briefing and requirements capture) to the needs and desires of their clients so that a medical facility design is produced which is truly aligned to the requirements of the hospital stakeholders. Semiotics, the “study” or “discipline” of signs aims to investigate the nature of signs (their inception, representation and meaning), whilst semiotics-rooted theories are concerned with investigating how meaning and understanding is mobilized between persons and between organisations. This paper details a semiotics-rooted research approach for investigating the interactions between hospital designers and stakeholders on a forthcoming NHS hospital project in the UK. A semiotics grounded study will potentially provide a deeper understanding of how meaning and understanding is established between hospital project stakeholders and construction professionals.

This paper intend to review recent advances in our understanding of programmed cell death, or apoptosis, and discuss implications of these basic science advances in the development of causes and potential treatments of a variety of diseases of the head and neck. Conclusions: apoptosis is now understood to be important in the normal development and survival of all multicellular organism. Deregulation of this normally tighly controlled process underlies a variety of disease states, including neoplasia, autoimmune disease, and disorders of the central nervous system. A better understanding of this process and regulation may help otolaryngologists better understand diseases relevant to this specialty and will lead to improved therapeutic interventions.

Objective. To identify preliminary core sets of outcome variables for disease activity and damage assessment in juvenile systemic lupus erythematosus (JSLE) and juvenile dermatomyositis (JDM). Methods. Two questionnaire surveys were mailed to 267 physicians from 46 different countries asking each member to select and rank the response variables used when assessing clinical response in patients with JSLE or JDM. Next, 40 paediatric rheumatologists from 34 countries met and, using the nominal group technique, selected the domains to be included in the disease activity and damage core sets for JSLE and JDM. Results. A total of 41 response variables for JSLE and 37 response variables for JDM were selected and ranked through the questionnaire surveys. In the consensus conference, domains selected for both JSLE and JDM activity or damage core sets included the physician and parent/patient subjective assessments and a global score tool. Domains specific for JSLE activity were the immunological tests and the kidney function parameters. Concerning JDM, functional ability and muscle strength assessments were indicated for both activity and damage core sets, whereas serum muscle enzymes were included only in the activity core set. A specific paediatric domain called 'growth and development' was introduced in the disease damage core set for both diseases and the evaluation of health-related quality of life was advised in order to capture the influence of the disease on the patient lifestyle. Conclusions. We developed preliminary core sets of measures for disease activity and damage assessment in JSLE and JDM. The prospective validation of the core sets is in progress.

Teledermatology is the area of Telemedicine that studies the application of telecommunication and information technology to dermatology practice without the presence of a specialist. It is a potential manner to deliver health planning, research, education, clinical meetings, second medical opinions and dermatological care to populations who cannot easily travel. The evolution, cost reduction and dissemination of telecommunication and information technology have enabled the implementation of low cost and comprehensive teledermatology systems to support clinical practice all over the world. © 2005 by Anais Brasileiros de Dermatologia.
