Do rural primary health care nurses feel equipped for palliative care?

Community primary health care nurses in rural and remote settings are required to provide palliative care as part of their generalist role. They have limited access to specialist medical and nursing support and sometimes there are no resident GPs. A study consisting of a mailed survey and follow-up interviews was conducted to explore the experiences of these nurses and to determine how personally and professionally equipped they felt for palliative care service provision. Most participants were registered nurses experienced in nursing and in rural and remote settings, who juggled multiple generalist work roles. They had only occasional palliative care patients, and more than half had provided palliative care for a friend or family member. Some nurses found palliative care rewarding, others preferred not to have to do it. However, even those who did not enjoy working with palliative care patients often went beyond the 'call of duty' to support a home death if that was what the patient wanted. Three-quarters had attended palliative care education in the last 2 years but 88% wanted more education. Barriers to education included competing work roles, work load, geographical isolation and lack of backfill. Support from managers and peers was considered important, as was accessing timely and relevant clinical support.

Screening for abdominal aortic aneurysm: does it affect men's quality of life?

A prospective study investigated the psychological wellbeing and quality of life of older rural men after a community-based screening for abdominal aortic aneurysm (AAA). Five hundred and sixteen men aged 65-74 years attended the screening program; 53 had an abnormal aorta detected. These and a subsample of men with a normal aorta were followed up 6 months post-screening. All men completed a pre-screening questionnaire including the Medical Outcomes Short Form 36v 2 (MOSF36) and Hospital Anxiety and Depression Scale (HADS). Six months after screening all 53 men with an abnormal and 130 with a normal aorta were sent a questionnaire including MOSF36 and HADS. Baseline and 6 month scores for both MOSF36 and HADS scores were compared between the two groups and within each group. Baseline scores for both MOSF36 and HADS were not significantly different between men who were subsequently diagnosed with an abnormal aorta and those with a normal aorta. After 6 months there was no difference in HADS scores but a significant increase in the MOSF36 dimension of general health. Those with a normal aorta reported better general health, social functioning and greater freedom from bodily pain. AAA screening appears highly acceptable to men in the target age group and future research should focus on implementation, cost effectiveness and collateral benefits of AAA screening.

Evaluation of home lead remediation in an Australian mining community.

In 1994 a comprehensive program was established to reduce children's blood lead levels in Broken Hill, NSW, Australia. Home remediation (abatement of lead hazards in a child's home) was included as part of a case management strategy for children with blood lead levels >or=15 microg/dL. Children with blood lead levels >or=30 microg/dL were offered immediate home remediation. Children with blood lead levels of 15-29 microg/dL were allocated to 'immediate' or 'delayed' home remediation; a subset of these participated in a randomized controlled trial (RCT) to evaluate the effectiveness of home remediation for reducing blood lead levels. One hundred and seventeen children received home remediation. One hundred and thirteen returned for follow-up blood tests, 88 of whom participated in the RCT. On average children's blood lead levels decreased by 1.7 microg/dL (10%) in the 6 months after remediation and by 2.2 microg/dL (13%) in the 6-12 months after remediation. However, remediation did not significantly change the rate of decline in blood lead levels (P=0.609). There was no evidence of association between change in children's blood lead levels and changes in lead loading in their homes. The results are consistent with the published literature, which suggests that home remediation does not reduce children's exposure to lead sufficiently to cause a moderate or greater decrease in their blood lead level. In communities where lead is widely dispersed, the study suggests that it is important to assess potential sources and pathways by which children are exposed to lead when developing an intervention plan, and the need for multiple interventions to effectively reduce blood lead levels. The findings reinforce the ongoing need for rigorous epidemiological evaluation of lead management programs to improve the evidence base, and for effective primary prevention to avoid children being exposed to lead in the first place.

Lead dust in Broken Hill homes: effect of remediation on indoor lead levels.

This study was undertaken to determine whether home remediation effectively reduced indoor lead levels in Broken Hill, a long-established silver-lead-zinc mining town in outback Australia. A before-after study of the effect of home remediation on indoor lead levels was embedded into a randomized controlled trial of the effectiveness of remediation for reducing elevated blood lead levels in young children. Moist towelettes were used to measure lead loading (microg/m2) on internal windowsills and internal and entry floors of 98 homes; samples were collected before, immediately after, and 2, 4, 6, 8, and 10 months after remediation. Data were log(10) transformed for the analysis. Remediation reduced average indoor lead levels by approximately 50%, and lead levels remained low for the duration of the follow-up period (10 months). The greatest gains were made in homes with the highest initial lead levels; homes with low preremediation lead levels showed little or no benefit. Before remediation, homes located in areas with high soil lead levels or with "poor" dust proofing had higher lead levels than those in areas with lower soil lead levels or with "medium" or "good" dust proofing; these relative differences remained after remediation. There was no evidence that lead loading was reduced by an increased opportunity to become aware of lead issues. We conclude that remediation is an effective strategy for reducing the lead exposure of children living in homes with high indoor lead levels.

Lead dust in broken hill homes--a potential hazard for young children?

OBJECTIVE: To determine the potential hazard posed by indoor lead dust to young children in Broken Hill, a silver-lead-zinc mining town in outback Australia, and the degree to which lead flux is influenced by factors such as geographical location, house construction type and condition. METHODS: 116 homes were selected and 93 (80%) studied from 10 localities in Broken Hill during the spring of 1995. Lead flux was measured using 85 mm diameter polystyrene petri dishes. Dishes were placed in four rooms of each house to collect dust over a six-to-eight-week period. Data on the location, condition and construction type of each house were recorded. Multiple linear regression was used to determine predictors of lead flux. Flux data were log transformed for the analysis. RESULTS: Average household lead flux varied nearly seven-fold across districts from a low of 166 (distant from the mines), to a high of 1,104 microg/m2/30-day period (adjacent to the mines). Houses that were 'adequately sealed' had 2.9 times the lead flux, and 'poorly sealed' houses 4.3 times the flux, of 'very well sealed' houses. Construction material did not significantly affect these flux levels, and no statistically significant interactions were found between house condition and location or house type. CONCLUSIONS: Many Broken Hill homes have high levels of lead flux that pose a potential risk to young children. Quantification of this hazard provides useful information for the community that can help focus efforts on actions required to minimise lead dust in the home. IMPLICATIONS: Household dust is a potential source of lead for young children in at-risk communities. Information on lead flux in homes can assist these communities and public health agencies to better understand and deal more effectively with the problem.
