The European Donor Hospital Education Programme (EDHEP): enhancing communication skills with bereaved relatives

Intensive care medical and nursing staff self-rate their communication skills as improved following attendance at the European Donor Hospital Education Programme (EDHEP) workshop. A prospective study was conducted to determine what impact EDHEP has on communication skills. Doctor-nurse pairs from 10 experimental and 10 control Intensive Care Units undertook two standardized simulated relative encounters (Breaking Bad News and Donation Request) at three measurement points (pre, post and follow-up). Nurses showed no change in communication skills. Experimental group doctors showed significant improvement in breaking bad news and requesting donation; most of these improvements were not maintained. Control group doctors showed some improvement in breaking bad news, indicating that participating in measurement by itself initiates some transient change in communication skills. Attendance at EDHEP does lead to significant improvement in some, but not all, communication skills essential in breaking bad news and requesting donation. Further research is necessary to determine what factors additional to EDHEP will contribute to enduring change in these particular skills.     

Renal allograft rejection: beta-chemokine involvement in the development of tubulitis

BACKGROUND: Tubulitis is a defining feature of renal allograft rejection. Graft dysfunction may result from damage inflicted on tubular epithelial cells by intratubular cytotoxic T lymphocytes. Graft cells are known to produce chemokines during acute rejection, but it is not known whether changes in expression of specific chemokines can influence the composition of the intratubular lymphocyte population. We examined expression of individual chemokines in biopsy sections showing different pathological rejection grades. METHODS: Sections from Banff-graded transplant biopsies were examined for the presence of beta-chemokines (MCP-1, MIP-1alpha, MIP-1beta, and RANTES) by immunofluorescence and semiquantitative confocal laser scanning microscopy. RESULTS: Beta-chemokines were expressed predominantly at the basolateral surface of tubular epithelial cells. Expression of MCP-1 and MIP-1beta was significantly higher in sections showing grade 2 rather than grade 1 acute rejection. RANTES and MIP-1alpha showed no significant variation in level of expression between rejection grades. CONCLUSIONS: Beta-chemokines are expressed by tubular epithelial cells during acute rejection. Consistent expression of RANTES and MIP-1alpha suggests a general role in recruiting T lymphocytes. However, MCP-1 and MIP-1beta may play a more subtle role in recruitment of specific T-cell subsets, such as Th1 cells, during acute cellular rejection.     

Effects of a multidisciplinary, post-discharge continuance of care intervention on quality of life, discharge satisfaction, and hospital length of stay: a randomized controlled trial.

OBJECTIVE: To determine the impact of a hospital-coordinated discharge care plan, involving a multidisciplinary team of primary health care providers, on hospital length of stay, quality of life, and both patient and general practitioner inclusion in, and satisfaction with, discharge procedures. DESIGN: This investigation comprised a prospective, randomized, controlled, clinical trial. SETTING: This multicentre and cross-jurisdictional study focused on areas of tertiary and primary health care as well as community allied health in Western Australia. PARTICIPANTS: Patients (n = 189) with chronic cardiorespiratory diagnoses were recruited from respiratory, cardiovascular, and general medical wards at two tertiary hospitals. INTERVENTION: Subjects were randomly assigned to one of two groups. Intervention group patients received a discharge care plan in accordance with that outlined in the Australian Enhanced Primary Care Package, completed before discharge and sent to the patient's general practitioner and other community service providers for review. Control patients were discharged under existing hospital processes. Outcome measures. Patients and general practitioners were surveyed pre-discharge and 7 days post-discharge for quality of life and opinion of discharge procedures. Hospital length of stay was also determined. RESULTS: Significant improvements in discharge planning involvement, health service access, confidence with discharge procedures, and opinion of discharge based on previous experience were seen for patients who received the discharge care plan. Further, improved perceptions of mental quality of life were observed within the first week post-discharge for intervention patients. Length of stay showed no difference between groups. Extent and speed of hospital-general practitioner communication were significantly improved via the intervention. CONCLUSIONS: Our results indicate that a multidisciplinary discharge care plan, initiated before separation, improves quality of life, involvement, and satisfaction with discharge care, and hospital-general practitioner integration. As such, it possesses benefits over current Western Australian hospital discharge procedures for the care of chronically ill populations.     

Closed loop control of anaesthesia: an assessment of the bispectral index as the target of control

We investigated the performance of a closed-loop system for administration of general anaesthesia, using the bispectral index as a target for control. One hundred patients undergoing gynaecological or general surgery were studied. In 60 patients, anaesthesia was maintained by intravenous infusion of a propofol/alfentanil mixture. In 40, an isoflurane/nitrous oxide based technique was used. For each technique, patients were randomly allocated to receive either closed-loop or manually controlled administration of the relevant agents (propofol/alfentanil or isoflurane), with an intra-operative target bispectral index of 50 in all cases. Closed-loop and manually controlled administration of anaesthesia resulted in similar intra-operative conditions and initial recovery characteristics. During maintenance of anaesthesia, cardiovascular and electro-encephalographic variables did not differ between closed-loop and manual control groups and deviation of bispectral index from the target value was similar. Intra-operative concentrations of propofol, alfentanil and isoflurane were within normal clinical ranges. Episodes of light anaesthesia were more common in the closed-loop group for patients receiving propofol/alfentanil anaesthesia and in the manual group for patients receiving isoflurane/nitrous oxide anaesthesia. Convenience aside, the closed-loop system showed no clinical advantage over conventional, manually adjusted techniques of anaesthetic administration.     

Estimates of chronic hepatitis B virus infection in Australia, 2000

Objectives : To estimate the prevalence of chronic hepatitis B virus (HBV) infection in Australia and attributable proportions associated with specific demographic groups at higher risk of infection.
Methods : Two methods were used to estimate prevalence of HBV surface antigen (HBsAg): (1) Population-based: results of a national serosurvey using sera collected opportunistically from laboratories across Australia were used for 1–59 year olds, with the HBsAg prevalence for 50–59 years extrapolated to the population aged 60 years and over; (2) Risk group-based: estimates for selected high-risk groups (injecting drug users, homosexual men, Indigenous Australians and people born in high-prevalence countries), using source data from antenatal HBV screening in central Sydney, HBV prevalence studies, and estimates for low-risk groups (first-time blood donors) were combined proportionally to their representation in the population.
Results : Prevalence of HBsAg in the national serosurvey increased, with age, from 0.0% for 1–4 and 5–9 year olds to 1.3–1.8% for the 40–49 year age group. Australian population HBsAg prevalence based on minimum and adjusted estimates from this serosurvey were 91,500 (0.49%) and 163,000 (0.87%) infections, respectively. The risk group method estimated an Australian HBsAg prevalence of 88,000 infections (0.47%). Approximately 50% of people with chronic HBV infection were estimated to be immigrants from either South-East Asia (33.3%) or North-East Asia (16.2%).
Conclusion : The range of estimates for chronic HBV infection in Australia is broad, reflecting the uncertainty in source data. A national blood survey encompassing a large and representative population sample may help to provide more accurate estimates. A large proportion of people with chronic HBV infection are Asian born.     

Double-vision: stereo photography in ophthalmology

In a world of computer-manipulated pictures easier than ever to achieve, many photographers and artists are called upon to combine images from various sources for illustrative purposes such as 'web pages', advertisements, public relations brochures, etc. To achieve an accurate interpretation in a finished composite illustration made up of photographs manipulated using a computer (or using conventional methods) the illustrator must be aware of the design and compositional elements of each image incorporated in the final illustration. Design and composition elements include: lighting direction and shadow, density, colour balance, etc. Yet another design and composition element too often overlooked is depth cues. Depth cues are the means by which the viewer perceives depth in a two-dimensional image, in this case: a photograph. This paper describes and illustrates the known depth cues contained in the photographic image.     

Advances in the treatment of chronic myeloid leukemia

Fortunately radiation accidents are infrequent occurrences, but since they have the potential of large scale events like the nuclear accidents of Chernobyl and Fukushima, preparatory planning of the medical management of radiation accident victims is very important. Radiation accidents can result in different types of radiation exposure for which the diagnostic and therapeutic measures, as well as the outcomes, differ. The clinical course of acute radiation syndrome depends on the absorbed radiation dose and its distribution. Multi-organ-involvement and multi-organ-failure need be taken into account. The most vulnerable organ system to radiation exposure is the hematopoietic system. In addition to hematopoietic syndrome, radiation induced damage to the skin plays an important role in diagnostics and the treatment of radiation accident victims. The most important therapeutic principles with special reference to hematopoietic syndrome and cutaneous radiation syndrome are reviewed.
