Empty rituals? A qualitative study of users' experience of monitoring & evaluation systems in HIV interventions in western India.

In global health initiatives, particularly in the context of private philanthropy and its 'business minded' approach, detailed programme data plays an increasing role in informing assessments, improvements, evaluations, and ultimately continuation or discontinuation of funds for individual programmes. The HIV/AIDS literature predominantly treats monitoring as unproblematic. However, the social science of audit and indicators emphasises the constitutive power of indicators, noting that their effects at a grassroots level are often at odds with the goals specified in policy. This paper investigates users' experiences of Monitoring and Evaluation (M&E) systems in the context of HIV interventions in western India. Six focus groups (totalling 51 participants) were held with employees of 6 different NGOs working for government or philanthropy-funded HIV interventions for sex workers in western India. Ten donor employees were interviewed. Thematic analysis was conducted. NGO employees described a major gap between what they considered their "real work" and the indicators used to monitor it. They could explain the official purposes of M&E systems in terms of programme improvement and financial accountability. More cynically, they valued M&E experience on their CVs and the rhetorical role of data in demonstrating their achievements. They believed that inappropriate and unethical means were being used to meet targets, including incentives and coercion, and criticised indicators for being misleading and inflexible. Donor employees valued the role of M&E in programme improvement, financial accountability, and professionalising NGO-donor relationships. However, they were suspicious that NGOs might be falsifying data, criticised the insensitivity of indicators, and complained that data were under-used. For its users, M& E appears an 'empty ritual', enacted because donors require it, but not put to local use. In this context, monitoring is constituted as an instrument of performance management rather than as a means of rational programme improvement.

Development of a Biomarker for Penconazole: A Human Oral Dosing Study and a Survey of UK Residents' Exposure.

Penconazole is a widely used fungicide in the UK; however, to date, there have been no peer-reviewed publications reporting human metabolism, excretion or biological monitoring data. The objectives of this study were to i) develop a robust analytical method, ii) determine biomarker levels in volunteers exposed to penconazole, and, finally, to iii) measure the metabolites in samples collected as part of a large investigation of rural residents' exposure. An LC-MS/MS method was developed for penconazole and two oxidative metabolites. Three volunteers received a single oral dose of 0.03 mg/kg body weight and timed urine samples were collected and analysed. The volunteer study demonstrated that both penconazole-OH and penconazole-COOH are excreted in humans following an oral dose and are viable biomarkers. Excretion is rapid with a half-life of less than four hours. Mean recovery of the administered dose was 47% (range 33%-54%) in urine treated with glucuronidase to hydrolyse any conjugates. The results from the residents' study showed that levels of penconazole-COOH in this population were low with >80% below the limit of detection. Future sampling strategies that include both end of exposure and next day urine samples, as well as contextual data about the route and time of exposure, are recommended.

Urinary biomarker concentrations of captan, chlormequat, chlorpyrifos and cypermethrin in UK adults and children living near agricultural land.

There is limited information on the exposure to pesticides experienced by UK residents living near agricultural land. This study aimed to investigate their pesticide exposure in relation to spray events. Farmers treating crops with captan, chlormequat, chlorpyrifos or cypermethrin provided spray event information. Adults and children residing ≤100 m from sprayed fields provided first-morning void urine samples during and outwith the spray season. Selected samples (1-2 days after a spray event and at other times (background samples)) were analysed and creatinine adjusted. Generalised Linear Mixed Models were used to investigate if urinary biomarkers of these pesticides were elevated after spray events. The final data set for statistical analysis contained 1518 urine samples from 140 participants, consisting of 523 spray event and 995 background samples which were analysed for pesticide urinary biomarkers. For captan and cypermethrin, the proportion of values below the limit of detection was greater than 80%, with no difference between spray event and background samples. For chlormequat and chlorpyrifos, the geometric mean urinary biomarker concentrations following spray events were 15.4 µg/g creatinine and 2.5 µg/g creatinine, respectively, compared with 16.5 µg/g creatinine and 3.0 µg/g creatinine for background samples within the spraying season. Outwith the spraying season, concentrations for chlorpyrifos were the same as those within spraying season backgrounds, but for chlormequat, lower concentrations were observed outwith the spraying season (12.3 µg/g creatinine). Overall, we observed no evidence indicative of additional urinary pesticide biomarker excretion as a result of spray events, suggesting that sources other than local spraying are responsible for the relatively low urinary pesticide biomarkers detected in the study population.

Comparison of residents' pesticide exposure with predictions obtained using the UK regulatory exposure assessment approach.

The UK regulatory methods currently used for estimating residents' potential pesticide exposure were assessed to determine whether they provide sufficiently conservative estimates. A non-random sample of 149 residents living within 100 m of fields where pesticides were sprayed provided first morning void urine samples one and/or two days after spraying. Using farmers' spray information, regulatory exposure assessment (REA) models were applied to estimate potential pesticide intake among residents, with a toxicokinetic (TK) model used to estimate urinary biomarker concentrations in the mornings of the two days following the spray. These were compared with actual measured urinary biomarker concentrations obtained following the spray applications. The study focused on five pesticides (cypermethrin, penconazole, captan, chlorpyrifos and chlormequat). All measured cypermethrin urinary biomarker levels were lower than the REA-predicted concentrations. Over 98% and 97% of the measured urinary biomarker concentrations for penconazole and captan respectively were lower than the REA-predicted exposures. Although a number of the chlorpyrifos and chlormequat spray-related urinary biomarker concentrations were greater than the predictions, investigation of the background urinary biomarker concentrations suggests these were not significantly different from the levels expected had no pesticide spraying occurred. The majority of measured concentrations being well below the REA-predicted concentrations indicate that, in these cases, the REA is sufficiently conservative.

Engaging with Community Researchers for Exposure Science: Lessons Learned from a Pesticide Biomonitoring Study.

A major challenge in biomonitoring studies with members of the general public is ensuring their continued involvement throughout the necessary length of the research. The paper presents evidence on the use of community researchers, recruited from local study areas, as a mechanism for ensuring effective recruitment and retention of farmer and resident participants for a pesticides biomonitoring study. The evidence presented suggests that community researchers' abilities to build and sustain trusting relationships with participants enhanced the rigour of the study as a result of their on-the-ground responsiveness and flexibility resulting in data collection beyond targets expected.

Parental perceptions of the impacts the built environment has on young children׳s health: a qualitative examination and lay assessment amongst residents in four Scottish communities.

The built environment is important for children׳s health and development. Qualitative research in four communities in Scotland explored with groups of parents of young children their lay perceptions of their local environment with specific reference to its impact upon their children׳s health. Valuing most strong supportive communities; good quality public spaces and social housing, parents׳ key concerns included anti-social behaviour, incivility and a range of locally-specific concerns. As knowledgeable key gatekeepers to children׳s use of home environments and public spaces, parent׳s qualitative lay input is important for the development of children׳s effective use of outdoor spaces and the built environment over the long term.

Biological monitoring of pesticide exposures in residents living near agricultural land.

BACKGROUND: There is currently a lack of reliable information on the exposures of residents and bystanders to pesticides in the UK. Previous research has shown that the methods currently used for assessing pesticide exposure for regulatory purposes are appropriate for farm workers 1. However, there were indications that the exposures of bystanders may sometimes be underestimated. The previous study did not collect data for residents. Therefore, this study aims to collect measurements to determine if the current methods and tools are appropriate for assessing pesticide exposure for residents living near agricultural fields. METHODS/DESIGN: The study will recruit owners of farms and orchards (hereafter both will be referred to as farms) that spray their agricultural crops with certain specified pesticides, and which have residential areas in close proximity to these fields. Recruited farms will be asked to provide details of their pesticide usage throughout the spray season. Informed consenting residents (adults (18 years and over) and children (aged 4-12 years)) will be asked to provide urine samples and accompanying activity diaries during the spraying season and in addition for a limited number of weeks before/after the spray season to allow background pesticide metabolite levels to be determined. Selected urine samples will be analysed for the pesticide metabolites of interest. Statistical analysis and mathematical modelling will use the laboratory results, along with the additional data collected from the farmers and residents, to determine systemic exposure levels amongst residents. Surveys will be carried out in selected areas of the United Kingdom over two years (2011 and 2012), covering two spraying seasons and the time between the spraying seasons. DISCUSSION: The described study protocol was implemented for the sample and data collection procedures carried out in 2011. Based on experience to date, no major changes to the protocol are anticipated for the 2012 spray season although the pesticides and regional areas for inclusion in 2012 are still to be confirmed.
