Health Economics in Public Health
BACKGROUND: Economic analysis is an important tool in deciding how to allocate scarce public health resources; however, there is currently a dearth of such analysis by public health researchers.
METHODS: Public health researchers and practitioners were surveyed to determine their current use of health economics and to identify barriers to use as well as potential strategies to decrease those barriers in order to allow them to more effectively incorporate economic analyses into their work. Data collected from five focus groups informed survey development. The survey included a demographic section and 14 multi-part questions. Participants were recruited in 2006 from three national public health organizations through e-mail; 294 academicians, practitioners, and community representatives answered the survey.
RESULTS: Survey data were analyzed in 2007. Despite an expressed belief in the importance of health economics, more than half of the respondents reported very little or no current use of health economics in their work. Of those using health economics, cost-benefit and cost-effectiveness analysis and determination of public health costs were cited as the measures used most frequently. The most important barriers were lack of expertise, funding, time, tools, and data, as well as discomfort with economic theory. The resource deemed most important to using health economics was collaboration with economists or those with economic training. Respondents indicated a desire to learn more about health economics and tools for performing economic analysis.
CONCLUSIONS: Given the importance of incorporating economic analysis into public health interventions, and the desire of survey respondents for more collaboration with health economists, opportunities for such collaborations should be increased
Methods Used in Economic Evaluations of Chronic Kidney Disease Testing — A Systematic Review
Background: The prevalence of chronic kidney disease (CKD) is high in general populations around the world. Targeted testing and screening for CKD are often conducted to help identify individuals that may benefit from treatment to ameliorate or prevent their disease progression. Aims: This systematic review examines the methods used in economic evaluations of testing and screening in CKD, with a particular focus on whether test accuracy has been considered, and how analysis has incorporated issues that may be important to the patient, such as the impact of testing on quality of life and the costs they incur. Methods: Articles that described model-based economic evaluations of patient testing interventions focused on CKD were identified through the searching of electronic databases and the hand searching of the bibliographies of the included studies. Results: The initial electronic searches identified 2,671 papers of which 21 were included in the final review. Eighteen studies focused on proteinuria, three evaluated glomerular filtration rate testing and one included both tests. The full impact of inaccurate test results was frequently not considered in economic evaluations in this setting as a societal perspective was rarely adopted. The impact of false positive tests on patients in terms of the costs incurred in re-attending for repeat testing, and the anxiety associated with a positive test was almost always overlooked. In one study where the impact of a false positive test on patient quality of life was examined in sensitivity analysis, it had a significant impact on the conclusions drawn from the model. Conclusion: Future economic evaluations of kidney function testing should examine testing and monitoring pathways from the perspective of patients, to ensure that issues that are important to patients, such as the possibility of inaccurate test results, are properly considered in the analysis

Ambient measurements of aromatic and oxidized VOCs by PTR-MS and GC-MS : intercomparison between four instruments in a boreal forest in Finland
Proton transfer reaction mass spectrometry (PTR-MS) and gas chromatography mass spectrometry GC-MS) are commonly used methods for automated in situ measurements of various volatile organic compounds (VOCs) in the atmosphere. In order to investigate the reliability of such measurements, we operated four automated analyzers using their normal field measurement protocol side by side at a boreal forest site. We measured methanol, acetaldehyde, acetone, benzene and toluene by two PTR-MS and two GC-MS instruments. The measurements were conducted in southern Finland between 13 April and 14 May 2012. This paper presents correlations and biases between the concentrations measured using the four instruments. A very good correlation was found for benzene and acetone measurements between all instruments (the mean R value was 0.88 for both compounds), while for acetaldehyde and toluene the correlation was weaker (with a mean R value of 0.50 and 0.62, respectively). For some compounds, notably for methanol, there were considerable systematic differences in the mixing ratios measured by the different instruments, despite the very good correlation between the instruments (mean R = 0.90). The systematic difference manifests as a difference in the linear regression slope between measurements conducted between instruments, rather than as an offset. This mismatch indicates that the systematic uncertainty in the sensitivity of a given instrument can lead to an uncertainty of 50-100% in the methanol emissions measured by commonly used methods.Peer reviewe
