Effectiveness of a Population Health Intervention on Disparities in Hypertension Control: A Stepped Wedge Cluster Randomized Clinical Trial.

BACKGROUND: Disparities in hypertension control across race, ethnicity, and language have been a long-standing problem in the United States. OBJECTIVE: To assess whether a multi-pronged intervention can improve hypertension control for a target population and reduce disparities. DESIGN: This stepped wedge cluster randomized trial was conducted at 15 adult primary care clinics affiliated with Massachusetts General Hospital. PCPs were randomized to receive the intervention in twelve groups. PARTICIPANTS: The target population was patients who met one of the following criteria based on self-identification: (1) Asian, Black, Indigenous, multi-racial, or other race; (2) Hispanic ethnicity; or (3) preferred language other than English. Reference population was White, English-speaking patients. INTERVENTIONS: PCPs were given access to an online equity dashboard that displays disparities in chronic disease management and completed an equity huddle with population health coordinators (PHCs), which involved reviewing target patients whose hypertension was not well controlled. In addition, community health workers (CHWs) were available in some practices to offer additional support. MAIN MEASURES: The primary outcome was change in the proportion of target patients meeting the hypertension control goal when comparing intervention and control periods. KEY RESULTS: Of the 365 PCPs who were randomized, 311 PCPs and their 10,865 target patients were included in the analysis. The intervention led to an increase in hypertension control in the target population (RD 0.9%; 95% CI [0.3,1.5]) and there was a higher intervention effect in the target population compared to the reference population (DiD 2.1%; 95% CI [1.1, 3.1]). CONCLUSIONS: Utilizing data on disparities in quality outcome measures in routine clinical practice augmented by clinical support provided by PHCs and CHWs led to modest, but statistically significant, improvement in hypertension control among BIPOC, Hispanic, and LEP patients.

Twelve-Month Outcomes of the First 1000 Days Program on Infant Weight Status.

OBJECTIVES: To examine the effects of the First 1000 Days intervention on the prevalence of infant overweight and maternal postpartum weight retention and care. METHODS: Using a quasi-experimental design, we evaluated the effects of the First 1000 Days program among 995 term, low-income infants and their mothers receiving care in 2 intervention community health centers and 650 dyads in 2 comparison health centers. The program includes staff training, growth tracking, health and behavioral screening, patient navigation, text messaging, educational materials, and health coaching. Comparison centers implemented usual care. Infant outcomes were assessed at 6 and 12 months, including weight-for-length z score and overweight (weight for length ≥97.7th percentile). We also examined maternal weight retention and receipt of care 6 weeks' post partum. RESULTS: The mean birth weight was 3.34 kg (SD 0.45); 57% of infants were Hispanic; 66% were publicly insured. At 6 months, infants had lower weight-for-length z scores (ß: -.27; 95% confidence interval [CI]: -.39 to -.15) and lower odds of overweight (adjusted odds ratio [OR]: 0.46; 95% CI: 0.28 to 0.76) than infants in comparison sites; differences persisted at 12 months (z score ß: -.18; 95% CI: -.30 to -.07; adjusted OR for overweight: 0.60; 95% CI: 0.39 to 0.92). Mothers in the intervention sites had modestly lower, but nonsignificant, weight retention at 6 weeks' post partum (ß: -.51 kg; 95% CI: -1.15 to .13) and had higher odds (adjusted OR: 1.50; 95% CI: 1.16 to 1.94) of completing their postpartum visit compared with mothers in the comparison sites. CONCLUSIONS: An early-life systems-change intervention combined with coaching was associated with improved infant weight status and maternal postpartum care.

Association of the First 1,000 Days Systems-Change Intervention on Maternal Gestational Weight Gain.

OBJECTIVE: To examine the associations of a clinical and public health systems-change intervention on the prevalence of excess gestational weight gain among high-risk, low-income women. METHODS: In a quasi-experimental trial, we compared the prevalence of excess gestational weight gain among women before (n=643) and after (n=928) implementation of the First 1,000 Days program in two community health centers in Massachusetts. First 1,000 Days is a systematic program starting in early pregnancy and lasting through the first 24 months of childhood to prevent obesity among mother-child pairs. The program includes enhanced gestational weight gain tracking and counseling, screening for adverse health behaviors and sociocontextual factors, patient navigation and educational materials to support behavior change and social needs, and individualized health coaching for women at high risk for excess gestational weight gain based on their prepregnancy body mass index (BMI) or excess first-trimester weight gain. The primary outcome was gestational weight gain greater than the 2009 Institute of Medicine (now known as the National Academy of Medicine) guidelines according to prepregnancy BMI. RESULTS: Among 1,571 women in the analytic sample, mean (SD) age was 30.0 (5.9) years and prepregnancy BMI was 28.1 (6.1); 65.8% of women started pregnancy with BMIs of 25 or higher, and 53.2% were Hispanic. We observed a lower prevalence (55.8-46.4%; unadjusted odds ratio [OR] 0.69, 95% CI 0.49-0.97), similar to results in a multivariable analysis (adjusted OR 0.69, 95% CI 0.49-0.99), of excess gestational weight gain among women with prepregnancy BMIs between 25 and 29.9. Among women who were overweight at the start of pregnancy, the lowest odds of excess gestational weight gain were observed among those with the most interaction with the program's components. Program enrollment was not associated with reduced excess gestational weight gain among women with prepregnancy BMIs of 30 or higher. CONCLUSIONS: Implementation of a systems-change intervention was associated with modest reduction in excess gestational weight gain among women who were overweight but not obese at the start of pregnancy.

Strengthening integration of clinical and public health systems to prevent maternal-child obesity in the First 1,000Days: A Collective Impact approach.

INTRODUCTION: Obesity interventions may be most effective if they begin in the earliest stages of life, support changes across family, clinical, and public health systems, and address socio-contextual factors. METHODS: The First 1000Days is a systematic program starting in early pregnancy lasting through the first 24months of infancy to prevent obesity among low-income mother-infant pairs in three community health centers in Massachusetts. The program uses a Collective Impact approach to create the infrastructure for sustained, system-wide changes for obesity prevention across early life clinical and public health services, including Obstetrics, Pediatrics, Adult Medicine, Behavioral Health, Nutrition, Community Health, the Women, Infants and Children (WIC) program, and the Maternal, Infant and Childhood Home Visiting program. Program components include 1) staff and provider training; 2) enhanced gestational weight gain and infant overweight tracking; 3) universal screening of adverse health behaviors and socio-contextual factors; 4) universal patient navigation to support individual behavior change and social needs, while strengthening integration of clinical and public health services; 5) individualized health coaching for mother-infant pairs at high risk of obesity; and 6) educational materials to support behavior change. RESULTS: A quasi-experimental evaluation design will examine changes, between 2015 and 2019, in gestational weight gain and prevalence of infant overweight from 0 to 24months of age. CONCLUSIONS: The First 1000Days program will examine the effectiveness of an early life obesity prevention program for mother-infant pairs. If successful, the program could provide a model for chronic disease prevention and health promotion among vulnerable families starting in early life.

Mortality predictors of snake bite envenomation in southern India--a ten-year retrospective audit of 533 patients.

Snake bite incidence is highest in Asia and sub-Saharan Africa. This retrospective audit of 533 adult patients, who had presented to the Emergency Department, collates clinical features, effect of pharmacologic interventions and the risk factors that influence morbidity and mortality. Dual toxicity, neurological and haematological, was observed in 30.4% of patients. Laboratory evidence of haematotoxicity was demonstrated in 314 (58.9%) and 40% demonstrated clinical evidence of bleeding. However, 7.3% of these patients did not have laboratory evidence of bleeding disorder (p < 0.001). Conversely, 60% did not have clinical evidence of bleeding, but demonstrated laboratory evidence of abnormal parameters. Acute kidney injury (AKI) was evident in 28% of patients and 15.3% required haemodialysis. About 25% with no haematotoxicity showed evidence of AKI. The majority received 6-12 vials of poly-valent anti-snake venom. Hypersensitivity reaction rate was 8% and predominantly anaphylactoid in nature. The length of hospital stay ranged from 2 to 28 days and 20% required mechanical ventilation. Overall mortality rate was 7.5% with significant association to AKI, haematotoxicity and assisted ventilation. The mortality rate was 18% in patients with pre-hospital delay more than 24 h, as against 5% when admitted within the above specified period (p = <0.001). The strength of this study is the accrued information of over a period of 10 years of snake-bite management through the Emergency Department of a university hospital setting. The limitations are the retrospective study design and the rejection percentage of 15.5% due to insufficient information from the total chart pool.
