IMPORTANCE There is consensus that incorporating clinical decision support into electronic health records will improve quality of care, contain costs, and reduce overtreatment, but this potential has yet to be demonstrated in clinical trials.OBJECTIVE To assess the influence of a customized evidence-based clinical decision support tool on the management of respiratory tract infections and on the effectiveness of integrating evidence at the point of care. DESIGN, SETTING, AND PARTICIPANTSIn a randomized clinical trial, we implemented 2 well-validated integrated clinical prediction rules, namely, the Walsh rule for streptococcal pharyngitis and the Heckerling rule for pneumonia. INTERVENTIONS AND MAIN OUTCOMES AND MEASURESThe intervention group had access to the integrated clinical prediction rule tool and chose whether to complete risk score calculators, order medications, and generate progress notes to assist with complex decision making at the point of care. RESULTSThe intervention group completed the integrated clinical prediction rule tool in 57.5% of visits. Providers in the intervention group were significantly less likely to order antibiotics than the control group (age-adjusted relative risk, 0.74; 95% CI, 0.60-0.92). The absolute risk of the intervention was 9.2%, and the number needed to treat was 10.8. The intervention group was significantly less likely to order rapid streptococcal tests compared with the control group (relative risk, 0.75; 95% CI, 0.58-0.97; P = .03). CONCLUSIONS AND RELEVANCEThe integrated clinical prediction rule process for integrating complex evidence-based clinical decision report tools is of relevant importance for national initiatives, such as Meaningful Use.TRIAL REGISTRATION clinicaltrials.gov Identifier: NCT01386047
Communicating scientific uncertainty about public health threats is ethically desirable but challenging due to its tendency to promote avoidance of choice options with unknown probabilities—a phenomenon known as “ambiguity aversion.” This study examined this phenomenon’s potential magnitude, its responses to different communication strategies, and its mechanisms. In a factorial experiment, 2701 adult laypersons in Spain read one of three versions of a hypothetical newspaper article describing a pandemic vaccine-preventable disease (VPD), but varying in scientific uncertainty about VPD risk and vaccine effectiveness: No-Uncertainty, Uncertainty, and Normalized-Uncertainty (emphasizing its expected nature). Vaccination intentions were lower for the Uncertainty and Normalized-Uncertainty groups compared to the No-Uncertainty group, consistent with ambiguity aversion; Uncertainty and Normalized-Uncertainty groups did not differ. Ambiguity-averse responses were moderated by health literacy and mediated by perceptions of vaccine effectiveness, VPD likelihood, and VPD severity. Communicating scientific uncertainty about public health threats warrants caution and further research to elucidate its outcomes, mechanisms, and management.
Primary immunodeficiencies (PI) are defects of the immune system that cause severe infections if not diagnosed and treated appropriately. Many patients with PI are undiagnosed, under-diagnosed, or misdiagnosed. Over the last decade, the Jeffrey Modell Foundation has implemented a Physician Education and Public Awareness Campaign (PEPAC) to raise awareness, assure early diagnosis, appropriate treatment, and management, with the overall goal to reduce morbidities and mortalities related to PI. In order to evaluate the PEPAC program, data are requested annually from physician experts within the Jeffrey Modell Centers Network (JMCN). The JMCN, consisting of 556 expert physicians, at 234 academic institutions, in 196 cities, and 78 countries spanning six continents, provides the infrastructure for referral, diagnosis, and appropriate treatment for patients with PI. In addition, the JMCN has made a significant contribution to the field of immunology with the discovery of new genes at the centers. These advancements have led to an overall better understanding of the immune system and will continue to improve quality of life of those with PI.
BackgroundMany employers use screenings to identify and recommend modification of employees' risk factors for type 2 diabetes, yet little is known about how often employees then engage in recommended behaviors and what factors influence engagement. We examined the frequency of, facilitators of, and barriers to engagement in recommended behaviors among employees found to have pre-diabetes during a workplace screening.MethodsWe surveyed 82 University of Michigan employees who were found to have pre-diabetes during a 2014 workplace screening and compared the characteristics of employees who 3 months later were and were not engaged in recommended behaviors. We interviewed 40 of these employees to identify the facilitators of and barriers to engagement in recommended behaviors.Results3 months after screening, 54% of employees with pre-diabetes reported attempting to lose weight and getting recommended levels of physical activity, had asked their primary care provider about metformin for diabetes prevention, or had attended a Diabetes Prevention Program. These employees had higher median levels of motivation to prevent type 2 diabetes (9/10 vs 7/10, p<0.001) and lower median estimations of their risk for type 2 diabetes (40% vs 60%, p=0.02). Key facilitators of engagement were high motivation and social and external supports. Key barriers were lack of motivation and resources, and competing demands.ConclusionsMost employees found to have pre-diabetes through a workplace screening were engaged in a recommended preventive behavior 3 months after the screening. This engagement could be enhanced by optimizing motivation and risk perception as well as leveraging social networks and external supports.
Severe combined immunodeficiency (SCID) is a group of syndromes resulting from genetic defects causing absence in T-cell and B-cell function, leading to serious and life-threatening infections. SCID is often fatal in the first 2 years of life if not identified and properly treated. While additional laboratory methods are being developed, the current T-cell receptor excision circle assay has proven to have outstanding specificity and sensitivity to accurately identify infants with SCID and other T-cell lymphopenia. The Jeffrey Modell Foundation (JMF) has a long history of advocacy and continues to promote newborn screening for SCID to be implemented in the United States and worldwide. Based on reports provided by California, New York, Texas, and Wisconsin on the results of their population based newborn screening programs, the overall incidence of SCID averaged 1:33,000 and T-cell lymphopenia averaged 1:6,600. JMF has developed a working algorithm or "decision tree", validated by peer-reviewed scientific literature, to be used by Public Health Departments and Health Ministries in states, countries, and regions throughout the world. This decision tool allows for local or regional data to be applied to measure the threshold and economic impact of implementing newborn screening for SCID and T-cell lymphopenia.
