Meta Analysis
Enhancing surveys of health care professionals: a meta-analysis of techniques to improve response.
Surveys involving health care providers are characterized by low and declining response rates (RRs), and researchers have utilized various strategies to increase survey RRs among health professionals. Based on 48 studies with 156 subgroups of within-study conditions, a multilevel meta-regression analysis was conducted to summarize the effects of different strategies employed in surveys of health professionals. An estimated overall survey RR among health professionals was 0.53 with a significant downward trend during the last half century. ⋯ Relative to the non-incentive subgroups, subgroups receiving monetary incentives were more likely to respond, while nonmonetary incentive groups were not significantly different from non-incentive groups. When number of follow-ups was considered, the one or two attempts of follow-up were found to be effective in increasing survey RR among health professionals. Having noted challenges associated with surveying health professionals, researchers must make every effort to improve access to their target population by implementing appropriate incentive- and design-based strategies demonstrated to improve participation rates.

Nonresponse bias in survey research can result in misleading or inaccurate findings and assessment of nonresponse bias is advocated to determine response sample representativeness. Four methods of assessing nonresponse bias (analysis of known characteristics of a population, subsampling of nonresponders, wave analysis, and linear extrapolation) were applied to the results of a postal survey of U. K. hospital organizations. ⋯ This study identified conflicting trends in the outcomes of analysis of nonresponse bias between the different methods applied and we were unable to validate the continuum of resistance theory as applied to organizational survey data. Further work is required to ensure established nonresponse bias analysis approaches can be successfully applied to organizational survey data. Until then, it is suggested that a combination of methods should be used to enhance the rigor of survey analysis.

Adverse events within health care settings can lead to two victims. The first victim is the patient and family and the second victim is the involved health care professional. The latter is the focus of this review. ⋯ The second victim phenomenon has a significant impact on clinicians, colleagues, and subsequent patients. Because of this broad impact it is important to offer support for second victims. When an adverse event occurs, it is critical that support networks are in place to protect both the patient and involved health care providers.

The study aimed to assess the attitudes of laypeople toward clinical placebo use. One of three imaginary stories was presented randomly in a popular news portal and participants (6,404 individuals) were asked to rate nine statements about it. In the stories, placebo therapy was used in a deceptive way. ⋯ According to participants' ratings, helping patients is more important than avoiding deception. They did not think that they would have felt deceived in the described situation or that treatment would have been successful in a fully informed case. Patients' attitude toward deceptive placebo use appears to be more pragmatic than has been previously supposed.

This article uses data from patients recruited using the 1994 case definition of chronic fatigue syndrome (CFS) to contrast those meeting criteria for the Myalgic Encephalomyelitis/chronic fatigue syndrome (ME/CFS) Canadian case definition with those that did not meet these criteria. The study also contrasts those meeting criteria for Myalgic Encephalomyelitis (ME) based on criteria from Ramsay and other theorists with those that did not meet the ME criteria. ⋯ The ME subset had more functional impairments, and more severe physical and cognitive symptoms than the subset not meeting ME criteria. When applied to a population meeting the 1994 CFS case definition, both ME/CFS and ME criteria appear to select a more severe subset of patients.
