In the Arab world, more than 40% of hypertensive individuals are unaware of their condition and over 19% have uncontrolled blood pressure, while less than 21% of diagnosed patients remain untreated.
Systematic Review
There are substantial gaps in the hypertension cascade of care in the Arab world, particularly in disease awareness and adequate blood pressure control, highlighting major barriers to proper diagnosis and management.
BACKGROUND: Hypertension is a leading risk factor for mortality and morbidity globally and in the Arab world. We summarize the evidence on awareness, treatment, and control of hypertension, to assess the extent of gaps in the hypertension continuum of care. We also assess the influence of gender and other social determinants at each level of the cascade of care. METHODS: We searched MEDLINE and SSCI databases for studies published between 2000 and 2017, reporting the rates of awareness, treatment or control of hypertension and/or their determinants in the Arab region. We included sources on both general populations and on clinical populations. The review process was based on the PRISMA guidelines. We present rates on the three stages of the care cascade corresponding to (1) awareness (2) treatment and (3) control of blood pressure, and estimated the losses that occur when moving from one stage to another. We also take stock of the evidence on social determinants and assess the statistical significance of gender differences in awareness, treatment and control. RESULTS: Data from 73 articles were included. Substantial proportions of hypertensives were lost at each step of the hypertension care continuum, with more missed opportunities for care resulting from lack of awareness of hypertension and from uncontrolled blood pressure. More than 40% and 19% of all hypertensive individuals were found to be unaware and to have uncontrolled blood pressure, respectively, but among individuals diagnosed with hypertension, less than 21% were untreated. Awareness rates were higher among women than men but this advantage was not consistently translated into better blood pressure control rates among women. CONCLUSIONS: This analysis of the cascade of care indicates that barriers to proper diagnosis and adequate control are greater than barriers to delivery of treatment, and discusses potential factors that may contribute to the gaps in delivery.
Akl et al. (Wed,) conducted a systematic review in Hypertension. Hypertension diagnosis and treatment was evaluated on Rates of hypertension awareness, treatment, and control. In the Arab world, more than 40% of hypertensive individuals are unaware of their condition and over 19% have uncontrolled blood pressure, while less than 21% of diagnosed patients remain untreated.
