Classifying perinatal mortality using verbal autopsy: is there a role for nonphysicians?

<p>Abstract</p> <p>Background</p> <p>Because of a physician shortage in many low-income countries, the use of nonphysicians to classify perinatal mortality (stillbirth and early neonatal death) using verbal autopsy could be useful.</p> <p>Objective</p> <p>To determine the extent to which underlying perinatal causes of deaths assigned by nonphysicians in Guatemala, Pakistan, Zambia, and the Democratic Republic of the Congo using a verbal autopsy method are concordant with underlying perinatal cause of death assigned by physician panels.</p> <p>Methods</p> <p>Using a train-the-trainer model, 13 physicians and 40 nonphysicians were trained to determine cause of death using a standardized verbal autopsy training program. Subsequently, panels of two physicians and individual nonphysicians from this trained cohort independently reviewed verbal autopsy data from a sample of 118 early neonatal deaths and 134 stillbirths. With the cause of death assigned by the physician panel as the reference standard, sensitivity, specificity, positive and negative predictive values, and cause-specific mortality fractions were calculated to assess nonphysicians' coding responses. Robustness criteria to assess how well nonphysicians performed were used.</p> <p>Results</p> <p>Causes of early neonatal death and stillbirth assigned by nonphysicians were concordant with physician-assigned causes 47% and 57% of the time, respectively. Tetanus filled robustness criteria for early neonatal death, and cord prolapse filled robustness criteria for stillbirth.</p> <p>Conclusions</p> <p>There are significant differences in underlying cause of death as determined by physicians and nonphysicians even when they receive similar training in cause of death determination. Currently, it does not appear that nonphysicians can be used reliably to assign underlying cause of perinatal death using verbal autopsy.</p

An evaluation of the effectiveness of the Zambian Health Worker Retention Scheme (ZHWRS) for rural areas

Background: Zambian Health Workers Retention Scheme (ZHWRS) commenced in 2003. The schemes' original aim was to retain and recruit Zambian doctors in rural and remote districts. The aim of the ZHWRS subsequently expanded to also include other health workers, in either rural or urban areas. The scheme was formulated to address, in part, the drastic shortage of health workers. Objectives: To evaluate the effectiveness of the ZHWRS in achieving its aim. Methods: The data on the number of health workers recruited by the ZHWRS and the spatial distribution of them was reviewed. A survey of health workers was undertaken to elicit their views of their working conditions, their job satisfaction and the effectiveness of retention schemes in retaining or increasing the numbers of and overall satisfaction of health workers. Results: The ZHWRS has not been successful in recruiting sufficient numbers of health workers to reverse the shortage problem or even to meet the modest targets of the scheme itself. However, these improvements do not decrease the likelihood of Department of Health (DoH) workers leaving their rural based positions. Conclusions: The ZHWRS has not fully met either its original or revised aims. The drastic shortage of health workers in Zambia continues

An exploratory study of the individual determinants of students sexual risk behaviour at a South African university

The prevalence of sexual risk behaviour is high on campuses at South African universities, putting many students at risk of HIV infection. This study explores individual influences on students' sexual risk-taking behaviour at the University of KwaZulu-Natal. The study collected cross-sectional data obtained between late 2008 and early 2010. A total of 80 in-depth interviews and four focus group discussions were conducted, allowing for an equal representation of males and females and a mix of different races (black, white, Indian and coloured) among students at two campuses (Howard College and Pietermaritzburg) and at different levels of study (undergraduate and postgraduate). The data were analysed using thematic analysis to identify factors associated with the students' sexual risk behaviour. Sexual risk behaviour was found to be influenced by a range of individual factors, especially: personal beliefs about long-term relationships; attitudes towards sex for variety; a drive for material wealth; a lack of satisfaction in relationships; levels of trust and attention; pursuit of the long-term goal of marriage; and HIV denialism. As young adults, university students lack experience in assessing influences on their risk-taking behaviour, thus they require education on the individual risk factors that put them at risk of acquiring HIV infection. Likewise, the nature of these factors pose significant challenges to reducing sexual risk behaviour among university students

An investigation on students' risky sexual behavior at KwaZulu-Natal University, South Africa, Durban

University environments are fertile grounds for risky sexual behaviors. This study investigated students' risky sexual practices at the University of KwaZulu-Natal in Durban, South Africa. Data were collected using quantitative and qualitative methods. A total of 1,405 questionnaires were administered, and 80 in-depth interviews and four focus group discussions were conducted. Quantitative data were analyzed using the Statistical Package for the Social Sciences (SPSS) for Windows 16.0. Qualitative data were analyzed using thematic analysis. The sample included 1,405 students, the majority (93%) of whom were never married and 97% were sexually experienced. Among males reporting male partnerships those who used alcohol were significantly more likely to report risky sexual practices. Among females reporting male partnerships, those 30 years and older were significantly less likely to report engaging in risky sexual behavior with male partners. Alcohol use was connected with inconsistent condom use and not using condom last sex among females. While low rates of condom use were a problem among older students aged 30 years and older, and risky sexual practices were more common among younger students. Risky sexual behaviors pose a big challenge for the successful HIV prevention interventions on university campuses
