A community-based access-enhanced intervention resulted in 51.6% of previously untreated hypertensives initiating treatment and 53.0% of uncontrolled hypertensives achieving blood pressure control after one year.

Does an access-enhanced community intervention improve hypertension screening, treatment, and control in a low socioeconomic status Asian community?
A community-based, access-enhanced intervention in a low-income Asian population improved hypertension treatment and control rates but was less effective at encouraging lifestyle changes and additional cardiovascular screening.
INTRODUCTION: This study investigated the effect of an access-enhanced intervention on hypertension screening and management, as well as on health behaviours among newly diagnosed hypertensives, in a multi-ethnic low socioeconomic status (SES) community. Factors associated with hypertension screening, treatment, and control in the community were also determined. MATERIALS AND METHODS: The study involved all residents aged ≥40 years in 2 public rental housing precincts (low SES), between 2009 and 2011, who were followed-up prospectively for 1 year after a 6-month community-based intervention comprising a 3-month access-enhanced screening component and a 3-month follow-up (outreach) component. Blood pressure was measured at baseline and follow-up. Multivariate Cox regression determined predictors of hypertension management at follow-up. RESULTS: The follow-up rate was 80.9% (467/577). At baseline, 60.4% (282/467) were hypertensive; 53.5% (151/282) were untreated; 54.2% (71/131) uncontrolled. One year later, postintervention, 51.6% (78/151) of untreated hypertensives were treated; combined with treated hypertensives previously uncontrolled, 53.0% (79/149) achieved control. Older age independently predicted treatment (adjusted relative risk, aRR = 1.98, CI, 1.08 to 3.65); majority ethnicity (aRR = 1.76, CI, 1.05 to 2.96), employment (aRR = 1.85, CI, 1.26 to 2.80) and newly treated hypertension (aRR=1.52, CI, 1.01 to 2.32) predicted control. A total of 52.4% (97/185) were irregularly screened at baseline; at follow-up 61.9% (60/97) were regularly screened. Cost and misperceptions were common barriers to screening and treatment. Newly diagnosed hypertensives were also less likely to go for additional cardiovascular screening (aRR = 0.54, CI, 0.29 to 0.99). CONCLUSION: An access-enhanced intervention had some success in improving hypertension management within low SES communities; however, it was less successful in improving cardiovascular risk management, especially in encouraging lifestyle changes and additional cardiovascular screening amongst newly diagnosed hypertensives.
Wee et al. (Sun,) conducted a cohort in Hypertension (n=577). Access-enhanced community-based screening and education intervention vs. Baseline (pre-intervention) was evaluated on Initiation of hypertension treatment among previously untreated hypertensives. A community-based access-enhanced intervention resulted in 51.6% of previously untreated hypertensives initiating treatment and 53.0% of uncontrolled hypertensives achieving blood pressure control after one year.
