Organisational and occupational risk factors associated with work related injuries among public hospital employees in Costa Rica

Aims: To explore the relation between occupational and organisational factors and work related injuries (WRI) among public hospital employees in Costa Rica.Methods: A cross-sectional survey was conducted among a stratified random sample of 1000 employees from 10 of the 29 public hospitals in Costa Rica. A previously validated, self-administered questionnaire which included occupational and organisational factors and sociodemographic variables was used. From the final eligible sample ( n = 859), a total of 842 ( response rate 98%) questionnaires were returned; 475 workers were analysed after excluding not-at-risk workers and incomplete questionnaires. WRI were computed for the past six months.Results: Workers exposed to chemicals (RR = 1.36) and physical hazards ( RR = 1.26) had higher WRI rate ratios than non-exposed workers. Employees reporting job tasks that interfered with safety practices ( RR = 1.46), and a lack of safety training ( RR = 1.41) had higher WRI rate ratios than their counterparts. Low levels of safety climate ( RR = 1.51) and safety practices ( RR = 1.27) were individually associated with an increased risk of WRI. Also, when evaluated jointly, low levels of both safety climate and safety practices showed the highest association with WRI ( RR = 1.92).Conclusions: When evaluated independently, most of the occupational exposures and organisational factors investigated were significantly correlated with an increased injury risk. As expected, some of these associations disappeared when evaluated jointly. Exposure to chemical and physical hazards, lack of safety training, and low levels of safety climate and safety practices remained significant risk factors for WRI. These results will be important to consider in developing future prevention interventions in this setting

Insights from the Field: Forests for Water

This issue brief describes analyses by the World Resources Institute (WRI) in support of emerging payments for watershed services (PWS) programs in two major watersheds in Maine and North Carolina and insights gleaned from work in progress. The three pilot initiatives discussed represent different approaches to establishing PWS programs that protect forests and other green infrastructure elements. In the Neuse River Basin in North Carolina, WRI is working with partners to identify beneficiaries and their water-related dependencies. We learned that clear documentation of the risks that beneficiaries face from water pollution, drought, and watershed degradation will help jump-start their participation in emerging PWS programs. In the Sebago Lake Watershed in Maine, WRI is finalizing a methodology for "green-gray" analysis that will provide beneficiaries a way to identify cost-effective green infrastructure solutions to water infrastructure demands of the 21 st century. Green infrastructure comprises all natural, seminatural and artificial networks of multifunctional ecological systems within, around, and between urban areas at all spatial scales. We learned that, to convince public investment managers to invest in green rather than gray, it is important to make the financial and business case using the same basic methodologies that are used for calculating the costs and benefits of conventional gray approaches. WRI is also working to develop PWS programs that help the city of Raleigh meet streetscape, conservation development, tree conservation, storm water management, and water quality goals contained in its Unified Development Ordinance in a least cost manner. We learned that market-based solutions like PWS can play a large role in land-use planning processes and that these processes may represent a large untapped demand driver for PWS programs throughout the Sout

Using CFCs and SF6 for groundwater dating : a SWOT analysis

A knowledge of the residence time of groundwater is of importance in understanding key issues in the evolution of water quality. Chlorofluorocarbons (CFCs) and sulphur hexafluoride (SF6) offer a convenient way of dating waters up to ~60 yrs old. In contrast to tritium, these gases are well-mixed in the atmosphere so their input functions are much less problematic. While any one of these gases can in principle provide a groundwater age, when two or more are measured on water samples the potential exists to distinguish between different modes of flow including piston flow, exponential flow and simple endmember mixing. As with all groundwater dating methods, caveats apply. Factors such as recharge temperature and elevation must be reasonably well-constrained. Mainly for SF6, the phenomenon of ‘excess air’ also requires consideration. Mainly for the CFCs, local sources of contamination need to be considered, as do redox conditions. For both SF6 and the CFCs, the nature and thickness of the unsaturated zone need to be factored into residence time calculations. This paper attempts a balanced look at the pros and cons of the trace-gas dating method

Reciprocal associations between depression, anxiety and work-related injury

OBJECTIVE: To examine the reciprocal longitudinal associations between depression or anxiety with work-related injury (WRI) at a large employer in the southwestern United States. METHOD: Three administrative datasets (2011–2013) were merged: employee eligibility, medical and prescription claims, and workers’ compensation claims. The sample contained 69 066 active employees. Depression and anxiety were defined as episodes of medical visits care (ie, claims) with corresponding ICD-9-CM codes. For an individual’s consecutive claims, a new case of depression or anxiety was defined if more than 8 weeks have passed since the prior episode. The presence of a workers’ compensation injury claim was used to identify WRI. Three-wave (health plan years 2011 or T1, 2012 or T2, and 2013 or T3) autoregressive cross-lagged models were used to estimate whether depression or anxiety predicted WRI, also if WRI predicted depression or anxiety in the following year(s). RESULTS: Depression predicted injury from T1 to T2 (β=0.127, p<0.001) and from T2 to T3 (β=0.092, p=0.001). Injury predicted depression from T1 to T3 (β=0.418, p<0.001). Effects of anxiety on WRI were small and inconsistent, from T1 to T2 (β=0.013, p=0.622) and from T2 to T3 (β=−0.043, p=0.031). T1 injury had a protective effect on T3 anxiety (β=−0.273, p<0.001). CONCLUSIONS: We found evidence of reciprocal effects for depression with WRI after adjustment for prior injuries and depression. The evidence for the relationship between anxiety and WRI is less clear. WRI prevention and management programmes should incorporate depression prevention and management

Power Sector Opportunities for Reducing Carbon Dioxide Emissions: Illinois

President Obama announced a national climate plan in June 2013 and directed the U.S. Environmental Protection Agency (EPA) to set carbon pollution standards for the power sector. Once EPA establishes those standards, states will implement their own plans for achieving those reductions. In this fact sheet, WRI examines existing tools Illinois can use to reduce power plant emissions
