BackgroundSelf-monitoring of blood pressure (BP) appears to reduce BP in hypertension but important questions remain regarding effective implementation and which groups may benefit most. This individual patient data (IPD) meta-analysis was performed to better understand the effectiveness of BP self-monitoring to lower BP and control hypertension.Methods and findingsMedline, Embase, and the Cochrane Library were searched for randomised trials comparing self-monitoring to no self-monitoring in hypertensive patients (June 2016). Two reviewers independently assessed articles for eligibility and the authors of eligible trials were approached requesting IPD. Of 2,846 articles in the initial search, 36 were eligible. IPD were provided from 25 trials, including 1 unpublished study. Data for the primary outcomes—change in mean clinic or ambulatory BP and proportion controlled below target at 12 months—were available from 15/19 possible studies (7,138/8,292 [86%] of randomised participants). Overall, self-monitoring was associated with reduced clinic systolic blood pressure (sBP) compared to usual care at 12 months (−3.2 mmHg, [95% CI −4.9, −1.6 mmHg]). However, this effect was strongly influenced by the intensity of co-intervention ranging from no effect with self-monitoring alone (−1.0 mmHg [−3.3, 1.2]), to a 6.1 mmHg (−9.0, −3.2) reduction when monitoring was combined with intensive support. Self-monitoring was most effective in those with fewer antihypertensive medications and higher baseline sBP up to 170 mmHg. No differences in efficacy were seen by sex or by most comorbidities. Ambulatory BP data at 12 months were available from 4 trials (1,478 patients), which assessed self-monitoring with little or no co-intervention. There was no association between self-monitoring and either lower clinic or ambulatory sBP in this group (clinic −0.2 mmHg [−2.2, 1.8]; ambulatory 1.1 mmHg [−0.3, 2.5]). Results for diastolic blood pressure (dBP) were similar. The main limitation of this work was that significant heterogeneity remained. This was at least in part due to different inclusion criteria, self-monitoring regimes, and target BPs in included studies.ConclusionsSelf-monitoring alone is not associated with lower BP or better control, but in conjunction with co-interventions (including systematic medication titration by doctors, pharmacists, or patients; education; or lifestyle counselling) leads to clinically significant BP reduction which persists for at least 12 months. The implementation of self-monitoring in hypertension should be accompanied by such co-interventions.

Systemic racism is a public health crisis. Systemic racism and racial/ethnic injustice produce racial/ethnic disparities in health care and health. Substantial racial/ethnic disparities in stroke care and health exist and result predominantly from unequal treatment. This special report aims to summarize selected interventions to reduce racial/ethnic disparities in stroke prevention and treatment. It reviews the social determinants of health and the determinants of racial/ethnic disparities in care. It provides a focused summary of selected interventions aimed at reducing stroke risk factors, increasing awareness of stroke symptoms, and improving access to care for stroke because these interventions hold the promise of reducing racial/ethnic disparities in stroke death rates. It also discusses knowledge gaps and future directions.

Objectives There is a shortage of trained healthcare personnel for cervical cancer screening in low/middle income countries. We evaluated the feasibility and limited efficacy of a smartphone-based training of community health nurses in Visual Inspection of the cervix under Acetic Acid (VIA). Methods During April-July of 2015 in urban Ghana, we designed and developed a study to determine the feasibility and efficacy of an mHealth supported training of community health nurses (CHNs) (n=15) to perform VIA and to use smartphone images to obtain expert feedback on their diagnoses within 24 hours and improve VIA skills retention. CHNs completed a 2-week on-site introductory training in VIA performance and interpretation followed by an ongoing 3-month text messaging supported VIA training by an expert VIA reviewer. Results CHNs screened 169 women at their respective community health centers while receiving real-time feedback from the reviewer. The total agreement rate between all VIA diagnoses made by all CHNs and the expert reviewer was 95%. The average rate of agreement between each CHN and the expert reviewer was 89.6% (Standard Deviation (SD)=12.8). The agreement rates for positive and negative cases were 61.5% and 98.0%, respectively. Cohen's kappa statistic was 0.67 (95% CI; 0.45-0.88). Around 7.7% of women tested VIA positive and received Cryotherapy or further services. Conclusions Our findings demonstrate the feasibility and efficacy of mHealth-supported VIA training of CHNs and has the potential to improve cervical cancer screening coverage in Ghana.

Cardiovascular disease (CVD) is a major contributor to the growing public health epidemic in chronic diseases. Much of the disease and disability burden from CVDs are in people under the age of 70 years in low- and middle-income countries (LMICs), formerly “the developing world”. The risk of CVD is heavily influenced by environmental conditions and lifestyle variables. In this article we review the scope of the CVD problem in LMICs, including economic factors, risk factors, at-risk groups, and explanatory frameworks that hypothesize the multi-factorial drivers. Finally we discuss current and potential interventions to reduce the burden of CVD in vulnerable populations including research needed to evaluate and implement promising solutions for those most at risk.

BACKGROUND Studies have shown that self-monitoring of blood pressure (BP) is effective when combined with co-interventions, but its efficacy varies in the presence of some co-morbidities. This study examined whether self-monitoring can reduce clinic BP in patients with hypertension-related co-morbidity. METHODS A systematic review was conducted of articles published in Medline, Embase, and the Cochrane Library up to January 2018. Randomized controlled trials of self-monitoring of BP were selected and individual patient data (IPD) were requested. Contributing studies were prospectively categorized by whether they examined a low/high-intensity co-intervention. Change in BP and likelihood of uncontrolled BP at 12 months were examined according to number and type of hypertension-related co-morbidity in a one-stage IPD meta-analysis. RESULTS A total of 22 trials were eligible, 16 of which were able to provide IPD for the primary outcome, including 6,522 (89%) participants with follow-up data. Self-monitoring was associated with reduced clinic systolic BP compared to usual care at 12-month follow-up, regardless of the number of hypertension-related co-morbidities (−3.12 mm Hg, [95% confidence intervals −4.78, −1.46 mm Hg]; P value for interaction with number of morbidities = 0.260). Intense interventions were more effective than low-intensity interventions in patients with obesity (P < 0.001 for all outcomes), and possibly stroke (P < 0.004 for BP control outcome only), but this effect was not observed in patients with coronary heart disease, diabetes, or chronic kidney disease. CONCLUSIONS Self-monitoring lowers BP regardless of the number of hypertension-related co-morbidities, but may only be effective in conditions such obesity or stroke when combined with high-intensity co-interventions.

Objective To determine whether racial and ethnic differences exist among patients with similar access to care, we examined outcomes after heart failure hospitalization within a large municipal health system. Background Racial and ethnic disparities in heart failure outcomes are present in administrative data, and one explanation is differential access to care. Methods We performed a retrospective cohort study of 8,532 hospitalizations of adults with heart failure at 11 hospitals in New York City from 2007 to 2010. Primary exposure was ethnicity/race, and outcomes were 30- and 90-day readmission and 30-day and one-year mortality. Generalized estimating equations were used to test for association between ethnicity/race and outcomes with covariate adjustment. Results Of included hospitalizations, 4,305 (51%) were for blacks, 2,449 (29%) were for Hispanics, 1,494 (18%) were for whites, and 284 (3%) were for Asians. Compared to whites, blacks and Asians had lower one-year mortality, with adjusted odds ratios (aORs) 0.75 (95% CI 0.59–0.94) and 0.57 (95% CI 0.38–0.85), whereas Hispanics were not significantly different (aOR 0.81: 95% CI 0.64–1.03). Hispanics had higher odds of readmission than whites, with aORs 1.27 (95% CI 1.03–1.57) at 30 days and 1.40 (95% CI 1.15–1.70) at 90 days. Blacks had higher odds of readmission than whites at 90 days (aOR 1.21: 95% CI 1.01–1.47). Conclusions Racial and ethnic differences in outcomes after heart failure hospitalization were present within a large municipal health system. Access to a municipal health system may not be sufficient to eliminate disparities in heart failure outcomes.
