Physician cardiovascular disease risk factor management: practice analysis in Japan versus the USA.

BACKGROUND: There is a 42% lower cardiovascular disease (CVD) death rate in Japan compared with the USA. Do physicians report differences in practice management of CVD risk factors in the two countries that might contribute to this difference? AIMS: CVD risk factor management reported by Japanese versus US primary care physicians was studied. METHODS: We undertook a descriptive study. An internet-based survey was conducted with physicians from each country. A convenience sample from the Shiga Prefecture in Japan and the state of Ohio in the USA resulted in 48 Japanese and 53 US physicians completing the survey. RESULTS: The survey group may not be representative of a larger sample. The survey demonstrated that 98% of responding Japanese physicians spend <10 minutes performing a patient visit, while 76% of US physicians spend 10 to 20 minutes (P < 0.0001) managing CVD risk factors. Eighty-seven percent of Japanese physicians (vs. 32% of US physicians) see patients in within three months for follow-up (P < 0.0001). Sixty-one percent of Japanese physicians allocate < 30% of visit time to patient education, whereas 60% of US physicians spend > 30% of visit time on patient education (P < 0.0001). Prescriptions are renewed very frequently by Japanese physicians (83% renewing less than monthly) compared with 75% of US physicians who renew medications every one to six months (P < 0.0001). Only 20% of Japanese physicians use practice guidelines routinely compared with 50% of US physicians (P = 0.0413). US physicians report disparities in care more frequently (P < 0.0001). Forty-three percent of Japanese (vs. 10% of US) physicians believe that they have relative freedom to practise medicine (P < 0.0001). CONCLUSION: Many factors undoubtedly affect CVD in different countries. The dominant ones include social determinants of health, genetics, public health and overall culture (which in turn determine diet, exercise and other factors). Yet the medical care system is an expensive component of society and its role in managing CVD risk factors deserves study. This descriptive report poses questions that require a more definitive study either with a more representative sample or direct observation of physician practices. US physicians responding to the survey reported greater administrative efforts, frustration and disparities in their practice, yet they followed practice guidelines more carefully. Japanese physicians responding reported focusing on quick, frequent visits that may have been more medication oriented, expecting more patient responsibility in self-care, which may have resulted in better chronic disease management. There may be differences in CVD risk factor management by primary care physicians in Japan versus the USA.

Changing physician practice behavior to measure and improve clinical outcomes.

Physician practice behavior often produces poor clinical outcomes in the management of cardiovascular disease risk factors in spite of effective treatments and guidelines. The behavior of 165 physicians in 2 settings (suburban and urban) was studied. After collecting baseline clinical data, including systolic blood pressure and low-density lipoprotein cholesterol, a series of interventions was conducted, including academic detailing. Low-density lipoprotein cholesterol decreased 10.4% in suburban patients with cardiovascular disease in the intervention group (P = .001) and 10.5% in the enhanced intervention group (P = .001). Systolic blood pressure decreased 1.11% (P = .357) in the intervention group and 5.13% in the enhanced intervention group (P < .001). In urban hypertensive patients, systolic blood pressure decreased 5.03% (P = .001) and low-density lipoprotein cholesterol decreased 7.01% (P < .001). Combining urban and suburban data, low-density lipoprotein cholesterol decreased 9.32% (P < .001) and systolic blood pressure decreased 4.00% (P < .001). Providing physicians with their clinical outcomes, reviewing national guidelines, and setting expectations, associated with modest practice systems innovations, can produce significant measurable clinical improvements.

Physician cardiovascular disease risk factor management: practices in France vs the United States.

Cardiovascular risk factor management by French vs US primary care physicians was studied. A survey was conducted that found that French physicians spend >20 minutes while US physicians spend five to 10 minutes (P<.001) addressing cardiovascular risk with patients. Fifty-three percent of French (vs 33% of US) physicians focus more on lifestyle modification and less on medication management (P<.0001). Sixty-nine percent of French physicians spend 0% to 20% of their time on administration while 65% of US physicians spend 10% to 30% (P=.0028). Fifty-one percent of French physicians see patients in one to three months for follow-up, while 51% of US physicians see patients in three to six months (P<.0001). Eighty-seven percent of French (vs 39% of US) physicians have guidelines available in the examination room either frequently or very frequently. US physicians report disparities in care more frequently than do French physicians (P<.0001). Forty-nine percent of French (vs 10% of US) physicians believe that they have relative freedom to practice medicine (P<.001). US physicians report greater administrative efforts, frustration, and disparities in their practice. French physicians focus more of their efforts on lifestyle management and see their patients more frequently and for a longer visit time.
