BACKGROUND: Understanding the social environmental around obesity has been limited by available data. One promising approach used to bridge similar gaps elsewhere is to use passively generated digital data. PURPOSE: This article explores the relationship between online social environment via web-based social networks and population obesity prevalence. METHODS: We performed a cross-sectional study using linear regression and cross validation to measure the relationship and predictive performance of user interests on the online social network Facebook to obesity prevalence in metros across the United States of America (USA) and neighborhoods within New York City (NYC). The outcomes, proportion of obese and/or overweight population in USA metros and NYC neighborhoods, were obtained via the Centers for Disease Control and Prevention Behavioral Risk Factor Surveillance and NYC EpiQuery systems. Predictors were geographically specific proportion of users with activity-related and sedentary-related interests on Facebook. RESULTS: Higher proportion of the population with activity-related interests on Facebook was associated with a significant 12.0% (95% Confidence Interval (CI) 11.9 to 12.1) lower predicted prevalence of obese and/or overweight people across USA metros and 7.2% (95% CI: 6.8 to 7.7) across NYC neighborhoods. Conversely, greater proportion of the population with interest in television was associated with higher prevalence of obese and/or overweight people of 3.9% (95% CI: 3.7 to 4.0) (USA) and 27.5% (95% CI: 27.1 to 27.9, significant) (NYC). For activity-interests and national obesity outcomes, the average root mean square prediction error from 10-fold cross validation was comparable to the average root mean square error of a model developed using the entire data set. CONCLUSIONS: Activity-related interests across the USA and sedentary-related interests across NYC were significantly associated with obesity prevalence. Further research is needed to understand how the online social environment relates to health outcomes and how it can be used to identify or target interventions.

To examine relations between infant social withdrawal behavior and maternal major depression (MDD), 155 mother-infant dyads were evaluated at the 6-month primary care visit. Maternal depression was determined based on a psychiatric interview. Infant social withdrawal behavior was assessed with the Alarm Distress Baby Scale (ADBB; A. Guedeney & J. Fermanian, 2001) based on videotaped mother-infant interactions. Of the sample, 18.7% of mothers were diagnosed with MDD, and 39.4% of infants scored above the clinical ADBB cutoff. Infants of depressed mothers were more likely to score positive on the ADBB (75.8 vs. 31.0%, p < .001) and showed distinct patterns of withdrawal behavior. Within the group of withdrawn infants, however, no differential patterns of behavior could be identified for infants of depressed mothers as compared to infants of mothers with no depression. These findings confirm the validity of the ADBB for detection of infant social withdrawal in the context of MDD. At the same time, they support evidence that the ADBB identifies nonspecific infant distress behaviors. Future studies will need to determine if and how positive ADBB screening results in the absence of maternal MDD might be associated with other maternal psychiatric disorders such as anxiety or borderline personality disorder. These results have important implications for screening guidelines in primary care.

OBJECTIVE: To describe the implementation and evaluation of a quality improvement intervention to increase new-patient access and decrease time-to-appointment wait for gastroenterology care. METHODS: We used a new model of care for gastroenterology evaluation. For specified clinical complaints, we offered new-patient appointments that were scheduled with a general pediatrician as an alternative to a subspecialist. A nurse navigator assisted in triaging patients. We analyzed all patient encounters over an 8-month period. To verify decreased time-to-appointment wait, mystery shoppers made semimonthly calls to centralized scheduling. We surveyed parents/families after visits with the pediatrician or subspecialists regarding satisfaction. RESULTS: The "access" pediatrician evaluated and treated approximately 40% of all new patients presenting to the division during the study period. Approximately 10% of new patients evaluated by the pediatrician (4% overall) were referred on to the subspecialist; fewer patients were reevaluated by the pediatrician in follow-up. The pediatrician ordered a minimal number of procedures. Semimonthly sampling revealed that overall new-patient access improved from an average time-to-appointment wait of 25 days to <1 day. Parent/family satisfaction was high for the patients evaluated by the pediatrician. CONCLUSIONS: Embedding a general pediatrician within a subspecialty division, and navigating patients to this provider, can increase access to treatment of new low- to moderate-complexity patients. The access pediatrician can maintain patient satisfaction, provide high-quality care, and decrease need for subspecialist evaluation. The model, in the setting of a large academic medical center, may provide a solution for barriers to patient care such as lengthy time-to-appointment wait.

OBJECTIVE: To identify the demographic, practice site, and clinical predictors of patient portal enrollment and activation among a pediatric primary care population. METHODS: We conducted a cross-sectional analysis of the primary care database of an academic children's hospital that introduced a patient portal in December 2007. RESULTS: We analyzed data for 84,015 children. Over a 4-year period, 38% enrolled in the portal; of these, 26% activated the account. The adjusted odds of portal enrollment was lower for adolescents, Medicaid recipients, low-income families, Asian or other race, and Hispanic ethnicity, and higher for patients with more office encounters, and presence of autism on the problem list. Once enrolled, the odds of portal activation [adjusted odds ratio (95% confidence interval)] was decreased for: Medicaid [0.55 (0.50-0.61)] and uninsured [0.79 (0.64-0.97)] (vs private insurance), black [0.53 (0.49-0.57)] and other [0.80 (0.71-0.91)] (vs white race), Hispanic ethnicity [0.77 (0.62-0.97)], and increased for: infant age [1.26 (1.15-1.37)] (vs school age), attendance at a resident continuity practice site [1.91 (1.23-2.97)], living further away from the practice (vs under 2 miles)[4.5-8.8 miles: 1.14 (1.02-1.29); more than 8.8 miles: 1.19 (1.07-1.33)], having more office encounters (vs 1-3) [4-7 encounters: 1.40 (1.24-1.59); 8-12 encounters: 1.58 (1.38-1.81); 13+ encounters: 2.09 (1.72-2.55)], and having 3 or more items on the problem list (vs 0) [1.19 (1.07-1.33)]. CONCLUSIONS: Sociodemographic disparities exist in patient portal enrollment/activation in primary care pediatrics. Attendance at a resident continuity practice site, living farther away from the practice, having more office encounters, and having more problem list items increased the odds of portal activation.

WHAT'S NEW: This is the first study of a pediatric hospitalist preoperative clinic. Pediatric hospitalists frequently make significant recommendations for patients with neuromuscular scoliosis prior to spinal surgery, especially those with medical complexity. Certain clinical criteria are statistically significantly associated with a hospitalist making a preoperative recommendation. OBJECTIVE: To assess (1) how frequently pediatric hospitalists make recommendations when evaluating preoperative neuromuscular scoliosis patients in anticipation of spinal fusion surgery and (2) evaluate if any clinical characteristics are associated with a higher likelihood of hospitalists doing so. METHODS: We performed a case series study using retrospective chart review of 214 patients scheduled for spinal fusion surgery for neuromuscular scoliosis from November 2009 through September 2012. RESULTS: We analyzed data for 214 patients aged 1 to 20 years (median, 13 years), of whom 155 (72%) received at least 1 specific preoperative recommendation, whereas 59 patients (28%) were cleared for surgery without specific recommendations. Underlying diagnosis (P = 0.024), nonambulatory status (odds ratio [OR]: 2.02, 95% confidence interval [CI]: 1.09-3.74), and increased number of preoperative medications (OR: 1.19, 95% CI: 1.06-1.34) were statistically significantly associated with an increased rate of receiving preoperative recommendations from the hospitalist. Comorbidities such as seizure disorder (OR: 2.68, 95% CI: 1.29-5.57) and gastrointestinal conditions (OR: 3.35, 95% CI: 1.74-6.45) were also statistically significantly associated with specific presurgical recommendations being made by the pediatric hospitalist. CONCLUSION: A pediatric hospitalist preoperative program for children with neuromuscular scoliosis in anticipation of spinal fusion surgery is associated with a high rate of recommendations being made, especially in children with certain clinical characteristics.

OBJECTIVE: The goal of this study was to assess outcomes and costs associated with hospitalist comanagement of medically complex children undergoing spinal fusion surgery for neuromuscular scoliosis. METHODS: A hospitalist comanagement program was implemented at a children's hospital. We conducted a retrospective case series study of patients during 2003-2008 to compare clinical and cost outcomes for 87 preimplementation patients, 40 patients during a partially implemented program, and 80 patients during a fully implemented program. RESULTS: When compared with preimplementation patients, full implementation program patients did not demonstrate a statistically significant difference in median length of stay on the medical/surgical unit after transfer from the PICU (median: 6 vs 8 days; P = .07). Patients in the full implementation group received fewer days of parenteral nutrition (median: 0 vs 6 days; P = .0006) and had fewer planned and unplanned laboratory studies on the inpatient unit. There was no statistically significant change in returns to the operating room (P = .08 between preimplementation and full implementation), other complications, or 30-day readmissions. Median hospital costs increased from preimplementation ($59372) to partial implementation ($89302) and remained elevated during full implementation ($81 651) compared with preimplementation (P = .004). Mean physician costs followed a similar trajectory from preimplementation ($18425) to partial implementation ($24101) to full implementation ($22578; P = .0006 [versus preimplementation]). CONCLUSIONS: A hospitalist comanagement program can significantly affect the care of medically complex children undergoing spinal fusion surgery. Initial program costs may increase.

BACKGROUND: The United Arab Emirates (UAE) is a rapidly developing country composed of a multinational population with varying educational backgrounds, religious beliefs, and cultural practices, which pose a challenge for population-based public health strategies. A number of public health issues significantly contribute to morbidity and mortality in the UAE. This article summarises the findings of a panel of medical and public health specialists from UAE University and various government health agencies commissioned to report on the health status of the UAE population. METHODS: A systematic literature search was conducted to retrieve peer-reviewed articles on health in the UAE, and unpublished data were provided by government health authorities and local hospitals. RESULTS: The panel reviewed and evaluated all available evidence to list and rank (1=highest priority) the top four main public health issues: 1) Cardiovascular disease accounted for more than 25% of deaths in 2010; 2) Injury caused 17% of mortality for all age groups in 2010; 3) Cancer accounted for 10% of all deaths in 2010, and the incidence of all cancers is projected to double by 2020; and 4) Respiratory disorders were the second most common non-fatal condition in 2010. CONCLUSION: The major public health challenges posed by certain personal (e.g. ethnicity, family history), lifestyle, occupational, and environmental factors associated with the development of chronic disease are not isolated to the UAE; rather, they form part of a global health problem, which requires international collaboration and action. Future research should focus on population-based public health interventions that target the factors associated with the development of various chronic diseases.
