The Observational Medical Outcomes Partnership (OMOP), a consortium of pharmaceutical, FDA, and academic researchers focuses on developing and evaluating electronic records-based methods for enhancing post-market drug safety surveillance. The OMOP 2011-2012 experiment consists of applying variants of seven analysis methods to five different EMR or claims databases to estimate the increase (decrease) in risk associated with drug-outcome pairs whose causal association has been previously established, and serves as a gold standard for comparison. Variants of each method can produce very different effect estimates, sometimes at odds with the gold standard. We explore the reasons behind this heterogeneity, and in doing …

Background: As a result of healthcare reform (HCR), insurance rates among Massachusetts (MA) residents increased from 86.6% (2006) to 94.4% (2010) and conferred a 7.6% higher probability of being insured compared to neighboring states. The effect of an individual mandate on insurance rates among trauma patients is unknown.
Methods: This was retrospective analysis of adult (18-64yrs) trauma patients from MA and surrounding states (NH, RI, CT, NY, VT) treated at our level 1 trauma center in central MA before (2004-2005) and after (2009-2010) MA-HCR. We estimated changes in insurance rates across time-periods and state-residence.
Results: Before MA-HCR, 76.7% (1647/2,148) of …

Why Are There Delays In Seeking Treatment For Childhood Diarrhoea In India?, Nisha Malhotra
Why Are There Delays In Seeking Treatment For Childhood Diarrhoea In India?, Nisha Malhotra

Abstract Aim To examine the barriers and facilitating factors for seeking treatment for childhood diarrhoea and to determine the main causes for delay in seeking treatment.
Methods Data from Indian Demographic and Health survey 2005–06 (NFHS-III) was used. Mothers were asked if their children (<5-years) had suffered from diarrhoea during the two weeks preceding the survey. Data were collected on the time of seeking treatment after start of the illness, and days waited to seek treatment after the diarrhoea started. Multivariate logistic regression analysis was performed to find the determinants of seeking treatment at the health facility and the factors responsible for the “delay” in seeking advice/treatment.
Results Out of a sample of 41,287 children, 3890 (9.4%) reportedly had diarrhoea. Sixty percent of children with diarrhoea were taken to a health facility. Mother's education till higher secondary and above (OR 1.65; 95% CI, 1.08 – 2.54), richest (OR 1.76; 95% CI, 1.24 – 2.48) wealth index, mother's lack of knowledge of oral …

Estimating Effects On Rare Outcomes: Knowledge Is Power, Laura B. Balzer, Mark J. Van Der Laan

Many of the secondary outcomes in observational studies and randomized trials are rare. Methods for estimating causal effects and associations with rare outcomes, however, are limited, and this represents a missed opportunity for investigation. In this article, we construct a new targeted minimum loss-based estimator (TMLE) for the effect of an exposure or treatment on a rare outcome. We focus on the causal risk difference and statistical models incorporating bounds on the conditional risk of the outcome, given the exposure and covariates. By construction, the proposed estimator constrains the predicted outcomes to respect this model knowledge. Theoretically, this bounding provides …

Background The interactive effects of different types of physical activity on cardiovascular disease (CVD) risk have not been fully considered in previous studies. We aimed to identify physical activity patterns that take into account combinations of physical activities and examine the association between derived physical activity patterns and risk of acute myocardial infarction (AMI). Methods We examined the relationship between physical activity patterns, identified by principal component analysis (PCA), and AMI risk in a case-control study of myocardial infarction in Costa Rica (N=4172), 1994-2004. The component scores derived from PCA and total METS were used in natural cubic spline models …
