ItemHealth services : knowledge, use and satisfaction of Afghan, Iranian and Iraqi settlers in Australia(Radcliffe Publishing, 2007)This paper reports the findings of a study examining the knowledge of, use of and satisfaction with local primary healthcare services reported by new arrivals to Australia from Iran, Iraq and Afghanistan. The study sample consisted of a purposive sample of 98 new settlers from the selected countries and used a semi-structured questionnaire and focus groups to attain information. Key findings were that friends and family were the greatest sources of health provider information and there was a lack of both more general health information and understanding of the health system. While study participants were able to access primary healthcare services and were generally satisfied, several major operational deficiencies were reported. General practitioners (GPs) were the major health providers for these groups. Health-seeking behaviours were strongly influenced by the country of birth in comparison with the other examined factors, and experiences of health service encounters also varied greatly between countries of birth. The facility’s proximity to the participant’s home was a strong influence in the selection of health services. The researchers recommend that a network of appropriately supported and staffed community health centres and/ or GP clinics is needed in areas where there are high concentrations of refugees and immigrants.

In 2002, 67% of eligible children were immunized, despite significant health sector and macro-economic financial constraints. A financial sustainability planning process for immunization was introduced in 2002, in order to mobilize national and international resources in support of the achievement of child health objectives. The aim of this paper is to outline this process, describe its early impact as an advocacy tool and recommend additional strategies for mobilizing additional resources for health. The methods of financial sustainability planning are described, including the advocacy strategies that were applied. Analysis of financial sustainability planning results indicates rising programme costs associated with new vaccine introduction and new technologies. Despite this, the national programme has demonstrated important early successes in using financial sustainability planning to advocate for increased mobilization of national and international sources of funding for immunization. The national immunization programme nevertheless faces formidable system and financial challenges in the coming years associated with rising costs, potentially diminishing sources of international assistance, and the developing role of sub-national authorities in programme management and financing.

ItemMalaria prevention in the expatriate and long-term traveller(Therapeutic Guidelines Limited, 2002-01-01)The prevention of malaria in expatriates and long-term travellers is complex. The traveller's doctor needs to consider the destination, the nature of the travel, the effectiveness and potential adverse effects of antimalarial medication, and the general health of the traveller. A preventative regimen can be devised combining several strategies including mosquito avoidance measures, chemoprophylaxis, emergency standby treatment and rapid self-diagnosis of malaria.

ItemHealth services utilisation and barriers for settlers from the Horn of Africa(WILEY, 2007-08)OBJECTIVE: To examine health services use and barriers for recently arrived immigrants from the Horn of Africa. METHOD: A cross-sectional study conducted in Melbourne, Australia, with a convenience sample of newly arrived immigrants (n=126) from Somalia (n=67), Ethiopia (n=24), Eritrea (n=26) and Sudan (n=6). RESULTS: GPs were the major health providers for participants, yet 22 (17%) respondents had not yet accessed health services in Australia. Thirty-three (26%) participants reported having had an unmet health concern for which they would have liked to seek advice. The most commonly identified barriers to health care and recommendations for improving services were associated with communication. CONCLUSIONS: This study illustrates unmet health needs among new arrivals and a need for linguistically appropriate information about the use of Australia's health system. IMPLICATIONS: The findings support increased use of professional interpreting services and support for new arrivals in making initial contact with the health system.

We assessed the prevalence of iron deficiency and anemia and associated risk factors in a community-based sample of women living in a rural province of northwest Vietnam. A cross-sectional survey, comprised of written questionnaires and laboratory analysis of hemoglobin (Hb), ferritin, transferrin receptor, and stool hookworm egg count, was undertaken, and the soluble transferrin receptor/log ferritin index was calculated. Of 349 non-pregnant women, 37.53% were anemic (Hb < 12 g/dL), and 23.10% were iron deficient (ferritin < 15 ng/L). Hookworm infection was present in 78.15% of women, although heavy infection was uncommon (6.29%). Iron deficiency was more prevalent in anemic than non-anemic women (38.21% versus 14.08%, P < 0.001). Consumption of meat at least three times a week was more common in non-anemic women (51.15% versus 66.67%, P = 0.042). Mean ferritin was lower in anemic women (18.99 versus 35.66 ng/mL, P < 0.001). There was no evidence of a difference in prevalence (15.20% versus 17.23%, P = 0.629) or intensity (171.07 versus 129.93 eggs/g, P = 0.412) of hookworm infection between anemic and non-anemic women. Although intensity of hookworm infection and meat consumption were associated with indices of iron deficiency in a multiple regression model, their relationship with hemoglobin was not significant. Anemia, iron deficiency, and hookworm infection were prevalent in this population. Intake of meat was more clearly associated with hemoglobin and iron indices than hookworm. An approach to addressing iron deficiency in this population should emphasize both iron supplementation and deworming.

METHODS: A total of 481 hospital staff members were recruited from 5 hospitals in Melbourne, Australia. They provided information about demographic variables and tuberculosis (TB) risk factors (ie, birth or travel in a country with a high prevalence of TB, working in an occupation likely to involve contact with M. tuberculosis or individuals with TB, or being a household contact of an individual with a proven case of pulmonary TB). The QFT-in tube test and the TST were administered in accordance with standardized protocols. Concordance between the test results and positive risk factors was analyzed using the kappa statistic, the McNemar test, and logistic regression. RESULTS: A total of 358 participants had both a TST result and a QFT-in tube test result available for comparison. There were fewer positive QFT-in tube test results than positive TST results (6.7% vs. 33.0%; P<.001). Agreement between the tests was poor (71%; kappa=0.16). A positive QFT-in tube test result was associated with birth in a country with a high prevalence of TB, the number of years an individual had lived in a country with a high prevalence of TB (ie, the effect of each additional year, treated as a continuous variable), and high-risk occupational contact. A positive TST result was associated with older age, receipt of bacille Calmette-Guérin (BCG) vaccination, and working in an occupation that involved patient contact. Receipt of BCG vaccination was most strongly associated with discordant results in instances in which the TST result was positive and the QFT-in tube test result was negative. CONCLUSION: In a population of healthcare staff with a low prevalence of TB and a significant rate of BCG vaccination, a positive QFT-in tube test result was associated with the presence of known risk factors for TB exposure, whereas a positive TST result was more strongly associated with a prior history of BCG vaccination.

ItemThe effectiveness of 4 monthly albendazole treatment in the reduction of soil-transmitted helminth infections in women of reproductive age in Viet Nam(ELSEVIER SCI LTD, 2009-07-15)Soil-transmitted helminth (STH) infections are endemic in northern Viet Nam where the climate and agricultural practices, such as the use of human excreta as fertiliser and the use of wastewater for irrigation, favour transmission. An intervention was conducted in Yen Bai Province, north-west Viet Nam, to measure the effectiveness of single dose albendazole (400mg) administered every 4 months for reducing the prevalence of STH infections in women of reproductive age. Stool samples were collected from women before the intervention and 3 and 12 months post-intervention. Information on a range of demographic and socio-economic variables was also collected to measure the major risk factors for high STH burden in this area. The prevalence of hookworm, Ascaris lumbricoides and Trichuris trichiura infection in the baseline sample of 366 women were 76.2%, 19.2% and 29.1%, respectively. In the women who were surveyed at baseline and again at 3 and 12 months after the intervention (n=118) cure rates were 71.3% for hookworm, 87.0% for A. lumbricoides and 81.4% for T. trichiura by the end of the 12 month study period (i.e. after three doses of albendazole). The main risk factor for hookworm infection was if women worked outside (odds ratio (OR)=3.2 (95% Confidence Interval (CI) 1.6-6.2), P=0.001) and the major risk factor for A. lumbricoides and T. trichiura infection was a lack of education. Low educational attainment was also the strongest risk factor for co-infection with all three species of STH (OR=7.5 (95% CI 3.4-16.4), P<0.001). The high rates of hookworm infection in this area of Viet Nam and the high cure rates for all three species of STH with 4 monthly albendazole treatment suggest that this programme should be expanded to all endemic areas in Viet Nam. The study also highlights the important contribution of education to women's health.

ItemPathways to malaria persistence in remote central Vietnam: a mixed-method study of health care and the community(BMC, 2009-03-23)BACKGROUND: There is increasing interest in underlying socio-cultural, economic, environmental and health-system influences on the persistence of malaria. Vietnam is a Mekong regional 'success story' after dramatic declines in malaria incidence following introduction of a national control program providing free bed-nets, diagnosis and treatment. Malaria has largely retreated to pockets near international borders in central Vietnam, where it remains a burden particularly among impoverished ethnic minorities. In these areas commune and village health workers are lynchpins of the program. This study in the central province of Quang Tri aimed to contribute to more effective malaria control in Vietnam by documenting the non-biological pathways to malaria persistence in two districts. METHODS: Multiple and mixed (qualitative and quantitative) methods were used. The formative stage comprised community meetings, observation of bed-net use, and focus group discussions and semi-structured interviews with health managers, providers and community. Formative results were used to guide development of tools for the assessment stage, which included a provider quiz, structured surveys with 160 community members and 16 village health workers, and quality check of microscopy facilities and health records at district and commune levels. Descriptive statistics and chi-square analysis were used for quantitative data. RESULTS: The study's key findings were the inadequacy of bed-nets (only 45% of households were fully covered) and sub-optimal diagnosis and treatment at local levels. Bed-net insufficiencies were exacerbated by customary sleeping patterns and population mobility. While care at district level seemed good, about a third of patients reportedly self-discharged early and many were lost to follow-up. Commune and village data suggested that approximately half of febrile patients were treated presumptively, and 10 village health workers did not carry artesunate to treat the potentially deadly and common P. falciparum malaria. Some staff lacked diagnostic skills, time for duties, and quality microscopy equipment. A few gaps were found in community knowledge and reported behaviours. CONCLUSION: Malaria control cannot be achieved through community education alone in this region. Whilst appropriate awareness-raising is needed, it is most urgent to address weaknesses at systems level, including bed-net distribution, health provider staffing and skills, as well as equipment and supplies.

ItemLessons learned from implementation of a demonstration program to reduce the burden of anemia and hookworm in women in Yen Bai Province, Viet Nam(BMC, 2009-07-28)BACKGROUND: Iron deficiency, anemia and hookworm disease are important public health problems for women of reproductive age living in developing countries and affect the health of newborns and infants. Iron supplementation and deworming treatment are effective in addressing these problems in both pregnant and non-pregnant women. Daily iron supplementation and deworming after the first trimester is recommended for pregnant women although these programs usually do not operate efficiently or effectively. Weekly iron-folic acid supplementation and regular deworming for non-pregnant women may be a viable approach for improving iron status and preventing anemia during the reproductive years. Addressing these diseases at a population level before women become pregnant could significantly improve women's health before and during pregnancy, as well as their infants' growth and development. METHODS AND RESULTS: This paper describes the major processes undertaken in a demonstration intervention of preventive weekly iron-folic acid supplementation with regular deworming for all 52,000 women aged 15-45 years in two districts of Yen Bai province, in northern Viet Nam. The intervention strategy included extensive consultation with community leaders and village, commune, district and provincial health staff, and training for village health workers. Distribution of the drugs was integrated with the existing health service infrastructure and the village health workers were the direct point of contact with women. Iron-folic acid tablets and deworming treatment were provided free of charge from May 2006. An independent Vietnamese NGO was commissioned to evaluate compliance and identify potential problems. The program resulted in effective distribution of iron-folic acid tablets and deworming treatment to all villages in the target districts, with full or partial compliance of 85%. CONCLUSION: Training for health staff, the strong commitment of all partners and the use of appropriate educational materials led to broad support for weekly iron-folic acid supplementation and high participation in the regular deworming days. In March 2008 the program was expanded to all districts in the province, a target population of approximately 250,000 WRA, and management was handed over to provincial authorities.
