Awareness of the Japanese Society of Hypertension Guidelines for the Management of Hypertension (JS']JSH 2000) and compliance to its recommendations: surveys in 2000 and 2004

Clinic physicians' awareness of the Japanese hypertension guideline ( JSH 2000) and compliance with its recommendations were assessed to derive policy implications for effective blood pressure control. Data were obtained from two postal questionnaire surveys conducted in 2000 and 2004, and subjects were 896 and 1425 clinic physicians, respectively, who were engaged in general internal medicine. Recognition rates of JSH 2000 were 63.1% ( n = 822) before its announcement in 2000 and 94.4% ( n = 1400) in 2004. Rates of access, familiarity and utilisation of JSH 2000 were 87.0, 81.6 and 68.9%, respectively ( n 1400) in 2004. As for major management strategies for low- risk hypertension: in 2000, for patients with 140 - 149/ 90 - 94 mmHg, 81.5% of 812 respondents performed lifestyle modification, and 11.2% prescribed medicines, whereas for patients with 150 - 159/ 95 - 99mmHg, 71.7% of 807 respondents prescribed medicines, and 24.3% conducted lifestyle modification; in 2004, 90.0% of 1384 respondents conducted lifestyle modification, 22.6% prescribed medicines, 2.5% referred patients to other facilities, and 6.4% did nothing. In 2004, 68.9% of 1388 respondents agreed with the new definition of hypertension, whereas 17.1% preferred 160/ 95mmHg. Respondents' age ( P < 0.05) and a percentage of hypertensives in daily patient load ( P < 0.0005) significantly associated with the choice of the old criteria. In conclusion, JSH 2000 achieved a substantial improvement in clinic physicians' awareness and their compliance to its recommendations on low- risk hypertension management. One of the strategies for further enhancement in their compliance with JSH 2004 would be its dissemination to those who are old and/or do not see hypertensive patients so frequently.
