PEPFAR support of alcohol-HIV prevention activities in Namibia and Botswana: a framework for investigation, implementation and evaluation.

BACKGROUND: The association between harmful use of alcohol and HIV infection is well documented. To address this dual epidemic, the US President's Emergency Plan for AIDS Relief (PEPFAR) developed and implemented a multi-pronged approach primarily in Namibia and Botswana. We present the approach and preliminary results of the public health investigative and programmatic activities designed, initiated and supported by PEPFAR to combat the harmful use of alcohol and its association as a driver of HIV morbidity and mortality from 2008 to 2013. APPROACH: PEPFAR supported comprehensive alcohol programming using a matrix model approach that combined the socio-ecological framework and the Alcohol Misuse Prevention and Intervention Continuum. This structure enabled seven component objectives: (1) to quantify harmful use of alcohol through rapid assessments; (2) to develop and evaluate alcohol-based interventions; (3) to promote screening programs and alcohol abuse resource services; (4) to support stakeholder networks; (5) to support policy interventions and (6) structural interventions; and (7) to institutionalize universal prevention messages. DISCUSSION: Targeted PEPFAR support for alcohol activities resulted in several projects to address harmful alcohol use and HIV. Components are graphically conceptualized within the matrix model, demonstrating the intersections between primary, secondary and tertiary prevention activities and individual, interpersonal, community, and societal factors. Key initiative successes included leveraging alcohol harm prevention activities that enabled projects to be piloted in healthcare settings, schools, communities, and alcohol outlets. Primary challenges included the complexity of multi-sectorial programming, varying degrees of political will, and difficulties monitoring outcomes over the short duration of the program.

Multistate outbreak of Escherichia coli O157:H7 infections associated with a national fast-food chain, 2006: a study incorporating epidemiological and food source traceback results.

A multistate outbreak of Escherichia coli O157:H7 infections occurred in the USA in November-December 2006 in patrons of restaurant chain A. We identified 77 cases with chain A exposure in four states - Delaware, New Jersey, New York, and Pennsylvania. Fifty-one (66%) patients were hospitalized, and seven (9%) developed haemolytic uraemic syndrome; none died. In a matched analysis controlling for age in 31 cases and 55 controls, illness was associated with consumption of shredded iceberg lettuce [matched odds ratio (mOR) 8·0, 95% confidence interval (CI) 1·1-348·1] and shredded cheddar cheese (mOR 6·2, CI 1·7-33·7). Lettuce, an uncooked ingredient, was more commonly consumed (97% of patients) than cheddar cheese (84%) and a single source supplied all affected restaurants. A single source of cheese could not explain the regional distribution of outbreak cases. The outbreak highlights challenges in conducting rapid multistate investigations and the importance of incorporating epidemiological study results with other investigative findings.

If you build it, will they come? Using a mobile safety centre to disseminate safety information and products to low-income urban families.

OBJECTIVE: To examine the utilisation-related outcomes associated with visiting the Johns Hopkins CareS (Children are Safe) Mobile Safety Center (MSC), a 40-foot vehicle designed to deliver effective injury prevention interventions and education to low-income urban families. DESIGN AND SETTING: Utilisation-related data were collected when the MSC was accessible at a community health centre and at community events from August 2004 to July 2006 in Baltimore City. SUBJECTS: Adults bringing their child for well child care at a community health centre and MSC visitors at community events. INTERVENTIONS: Low-cost safety products and free personalized educational services are provided on the MSC, which replicates a home environment and contains interactive exhibits. MAIN OUTCOME MEASURES: Perceived benefits of visiting the MSC; products and services received. RESULTS: MSC visitors (n = 83) and non-visitors (n = 127) did not differ in sociodemographic and injury-related characteristics; 96% of visitors reported learning something new as a result of their visit and 98% would recommend the MSC. During the first 2 years of operation, the MSC made 273 appearances, serving 6086 people. Home child safety products accounted for 71% of the 559 products distributed; educational materials made up 87% of the 7982 services received. Car safety seats accounted for 23% of the products distributed; installations made up 4% of the services received. CONCLUSIONS: This approach to disseminating injury prevention interventions holds promise for enhancing the appeal of safety information and increasing the protection of children.

Self-limited febrile syndromes temporally associated with the use of propofol for sedation in gastrointestinal endoscopic procedures.

PURPOSE: To investigate cases of febrile illnesses in patients who received propofol for sedation during gastrointestinal endoscopy. METHODS: Active case finding for patients who underwent endoscopy between 1 April and 30 May 2007 and suffered unexplained fever, chills, or myalgia within 48 hour after the procedure. We reviewed medications and clinical practices to find factors associated with the reactions. RESULTS: Seventy-four cases at eight facilities in five states were identified yielding a rate of 36 reactions per 1000 procedures, compared with a baseline rate of 0.6 per 1000. The majority of patients experienced self-limited fever (89.2%), chills (73.0%), or myalgia (63.5%). Blood samples from five patients were collected for culture; no organisms grew. All health care facilities that reported cases and fully participated in the investigation (n = 7) had received a common lot of propofol just before recognition of the first case. Bacterial endotoxin and sterility testing on unopened vials from this lot of propofol showed no abnormalities. Cases terminated after facilities stopped using the associated lot of propofol. CONCLUSIONS: We found a temporal association between a particular lot of propofol and an outbreak of febrile illnesses at several healthcare facilities performing endoscopy. When propofol is used to sedate patients for endoscopy, fever is a rare outcome and healthcare professionals should investigate clusters of these reactions. Post-procedure surveillance is important to identify possible medication reactions.

Community-based assessment of infant feeding practices within a programme for prevention of mother-to-child HIV transmission in rural Zimbabwe.

OBJECTIVE: To describe the infant feeding practices and attitudes of women who used prevention of mother-to-child transmission of HIV (PMTCT) services in rural Zimbabwe. DESIGN: A cross-sectional study including structured interviews and focus group discussions was conducted between June 2003 and February 2004. SETTING: The study took place in Murambinda Mission Hospital (Buhera District, Manicaland Province), the first site offering PMTCT services in rural Zimbabwe. SUBJECTS: The interviews targeted HIV-infected and HIV-negative women who received prenatal HIV counselling and testing and minimal infant feeding counselling, and who delivered between 15 August 2001 and 15 February 2003. The focus groups were conducted among young and elderly men and women. RESULTS: Overall, 71 HIV-infected and 93 HIV-negative mothers were interviewed in clinics or at home. Most infants (97%) had ever been breast-fed. HIV-negative mothers introduced fluids/foods other than breast milk significantly sooner than HIV-infected mothers (median 4.0 vs. 6.0 months, P = 0.005). Infants born to HIV-negative mothers were weaned significantly later than HIV-exposed infants (median 19.0 vs. 6.0 months, P = 10(-5)). More than 90% of mothers reported that breast-feeding their infant was a personal decision, a third of whom also mentioned having taken into account health workers' messages. CONCLUSION: The HIV-infected mothers interviewed were gradually implementing infant feeding practices recommended in the context of HIV. Increased infant feeding support capacity in resource-limited rural populations is required, i.e. training of counselling staff, decentralised follow-up and weaning support.

Improved knowledge and practices among end-users of mother-to-child transmission of HIV prevention services in rural Zimbabwe.

OBJECTIVE: To evaluate the influence of a prevention of mother-to-child transmission of HIV advocacy and mobilization campaign on awareness and knowledge levels within the community. METHOD: We used a knowledge, attitudes and practices survey to collect baseline data in November 2002 and again in July 2004 for evaluation purposes. RESULTS: A total of 351 women attending healthcare services were interviewed each time. The proportion of women aware of the service increased from 48.0% in 2002 to 82.8% in 2004 (OR = 4.9, 95% CI 3.3-7.3, P = 0.001). Exclusive breastfeeding was identified as a mother-to-child transmission risk factor by 27.1% in 2002 and by 55.8% of respondents in 2004 (OR = 2.9, CI 2.1-4.2, P = 0.001). Although most interviewees agreed that the prevention of sexual transmission of HIV was the best strategy for prevention of mother-to-child transmission of HIV (88.3% in 2002 and 96.4% in 2004), few reported having ever used a male condom (24.8% in 2002 vs. 29.8% in 2004, P = 0.16). DISCUSSION: Prevention of mother-to-child transmission of HIV strategies at both individual and community level were still insufficiently understood and applied. Targeted educational messages and communication for social change need to be combined. Knowledge, attitudes and practices surveys can be used to monitor programme progress.

Anaesthesia associated mortality in a district hospital in Zimbabwe: 1994 to 2001.

OBJECTIVE: To describe anaesthetic associated mortality in a district hospital in Zimbabwe. DESIGN: A retrospective descriptive study of anaesthesia associated mortality over an eight year period. SETTING: Murambinda Mission Hospital: a 120 bed rural district hospital in Zimbabwe. SUBJECTS: All patients who died within 24 hours of receiving an anaesthetic. MAIN OUTCOME MEASURES: The overall mortality rate (OMR), being all deaths up to 24 hours after an anaesthetic. Avoidable anaesthetic mortality rate (AMR), are deaths in which correctable anaesthetic factors played a major role. RESULTS: An overall mortality rate (OMR) of 1:344 (2.9 deaths/1 000 anaesthetics) and avoidable mortality rate (AMR) for anaesthesia of 1:482 (2.1 deaths/1 000 anaesthetics) are reported. Factors under the control of the anaesthetist accounted for 72% of mortalities (AMR:OMR). All were emergency obstetric patients and had emergency surgery. The hospital maternal mortality rate of 360 per 100 000 and an operative obstetric mortality of 1:293 (3.4 deaths/1 000) are reported. CONCLUSIONS: Most of the anaesthetic factors are preventable. These results, although very poor, are consistent with reports from hospitals in the region. By comparison, developed countries are at least 10 times better. Improving the provision, skills, support and profile of anaesthesia providers in the care of peri operative patients, would reduce anaesthesia-associated factors in peri operative mortality. A system of national audit data collection comparable to the CEPOD or Confidential Enquiry into Maternal Deaths is overdue in Zimbabwe.
