Use of a computerized decision aid for developmental surveillance and screening: a randomized clinical trial

Abstract: Importance Developmental delays and disabilities are common in children. Research has indicated that intervention during the early years of a child's life has a positive effect on cognitive development, social skills and behavior, and subsequent school performance. Objective To determine whether a computerized clinical decision support system is an effective approach to improve standardized developmental surveillance and screening (DSS) within primary care practices. Design, Setting, and Participants In this cluster randomized clinical trial performed in 4 pediatric clinics from June 1, 2010, through December 31, 2012, children younger than 66 months seen for primary care were studied. Interventions We compared surveillance and screening practices after adding a DSS module to an existing computer decision support system. Main Outcomes and Measures The rates at which children were screened for developmental delay. Results Medical records were reviewed for 360 children (180 each in the intervention and control groups) to compare rates of developmental screening at the 9-, 18-, or 30-month well-child care visits. The DSS module led to a significant increase in the percentage of patients screened with a standardized screening tool (85.0% vs 24.4%,P Conclusions and Relevance Using a computerized clinical decision support system to automate the screening of children for developmental delay significantly increased the numbers of children screened at 9, 18, and 30 months of age. It also significantly improved surveillance at other visits. Moreover, it increased the number of children who ultimately were diagnosed as having developmental delay and who were referred for timely services at an earlier age.

Acceptance of dementia screening in continuous care retirement communities: a mailed survey.

Abstract: Background In a recent systematic review of the evidence for dementia screening to support recommendations from the US Preventive Services Task Force, we found no evidence regarding the interest or willingness of older adults to be screened, and insufficient evidence to provide an estimate of the potential harms of dementia screening. Objective In an attempt to address the acceptability of dementia screening, we asked older adults living in two Continuous Care Retirement Communities (CCRC) if they would agree to routine screening for memory problems. Design Cross-sectional study using self-administered mailed survey questionnaires. Setting Two CCRCs in Orange County, North Carolina. Participants 500 residents of the independent living section of CCRCs. Results There was a 64% survey response rate. Of these, 49% of participants stated they would agree to routine screening for memory problems. In comparison to people who would not agree to routine memory screening, those who accepted memory screening were more likely to accept depression screening, be male, use drug-administration assisted devices, and take more medications. Conclusion Approximately half of the residents in this affluent residential community setting were not willing to be screened routinely for memory problems. This high refusal rate indicates that dementia screening may be associated with perceived harms. We must improve our understanding of the decision-making process driving individual's beliefs and behaviors about dementia screening before implementing any broad-based screening initiatives for dementia or cognitive impairment.

Choosing between predictors of fractures.

Abstract: The identification of those at highest risk of osteoporotic fractures is a clinical goal that requires appropriate statistical comparisons of potential predictors of fractures. This article provides a formal approach for comparing individual predictors (e.g., bone mass at one site vs bone mass at another), or sets of predictors (e.g., bone mass vs other risk factors), and contrasts newer methods, such as bootstrapping, to receiver-operating-characteristics (ROC) curves, which have been previously used. The advantages of the bootstrapping approach are illustrated using time-to-fracture data from a published study demonstrating the use of baseline bone mass measurements in the prediction of fractures in 521 subjects with variable lengths of follow-up, extending to 12.5 years. Bone mineral density (BMD) was shown to be significantly better than bone mineral content (BMC) in predicting fractures in free-living subjects, but not in retirement-community subjects. Bone mineral apparent density (BMAD) was also compared with BMC and BMD and shown not to improve fracture prediction in these subjects.

Spatial relationships between lead sources and children’s blood lead levels in the urban center of Indianapolis (USA)

Abstract: Urban children remain disproportionately at risk of having higher blood lead levels than their suburban counterparts. The Westside Cooperative Organization (WESCO), located in Marion County, Indianapolis, Indiana, has a history of children with high blood lead levels as well as high soil lead (Pb) values. This study aims at determining the spatial relationship between soil Pb sources and children’s blood lead levels. Soils have been identified as a source of chronic Pb exposure to children, but the spatial scale of the source–recipient relationship is not well characterized. Neighborhood-wide analysis of soil Pb distribution along with a furnace filter technique for sampling interior Pb accumulation for selected homes (n = 7) in the WESCO community was performed. Blood lead levels for children aged 0–5 years during the period 1999–2008 were collected. The study population’s mean blood lead levels were higher than national averages across all ages, race, and gender. Non-Hispanic blacks and those individuals in the Wishard advantage program had the highest proportion of elevated blood lead levels. The results show that while there is not a direct relationship between soil Pb and children’s blood lead levels at a spatial scale of ~100 m, resuspension of locally sourced soil is occurring based on the interior Pb accumulation. County-wide, the largest predictor of elevated blood lead levels is the location within the urban core. Variation in soil Pb and blood lead levels on the community level is high and not predicted by housing stock age or income. Race is a strong predictor for blood lead levels in the WESCO community.
