Objective To analyze the number,distribution,drug use and drug cost of hypertension patients in outpatient departments in Fuxing Hospital Affiliated to Capital Medical University,and to analyze the administration of β receptor blockers in the hospital. Methods Donghua Hospital Information System was used to collect the data of 22 399 hypertension patients in outpatient departments from July 26,2007 to January 31,2008,including sex,age,blood pressure grade,drug administration,and drug cost. According to the specific alities of the physicians in outpatient department they visited,the patients were divided into 3 groups: cardiovascular group,non-cardiovascular group,and non-internal medicine group. The used antihypertensive drugs were divided into 8 types,including β receptor blockers,α receptor blockers,angiotensin-converting enzyme inhibitors (ACEI),angiotensin-receptor antagonists (ARB),calcium antagonists,diuretics,traditional Chinese materia medica(TCMM),and traditional antihypertensive drug compounds. The general data of the patients,such as blood pressure grade,age,sex,etc,and the administration of different types of antihypertensive drugs were compared among 3 groups. Results In the 3 groups,there were more female hypertension patients than male ones (53.77% vs 46.33%,P<0.01). There were more patients with grade Ⅲ hypertension in cardiovascular group than in non-cardiovascular group and non-internal medicine group(P<0.01). The mean other than TCMM drug cost per visit was the highest (RMB 296.75 yuan),and the mean TCMM cost per visit was the lowest (RMB 0.00 yuan) in cardiovascular group. In non-internal medicine group,the mean TCMM cost per visit was higher than the mean other than TCMM drug cost per visit(P<0.01). The first 3 most commonly prescribed drugs were calcium antagonist,β receptor blockers,and ACEI sequentially in non-cardiovascular and non-internal medicine groups,vs β receptor blockers,calcium antagonists,and diuretics sequentially in cardiovascular group. Conclusion The cardiovascular physicians generally prescribe antihypertensive drugs according to the guide. The TCMM is less used in cardiovascular group than in other two groups. Currently,in Fuxing Hospital,β receptor blockers are the first choice among all antihypertensive drugs.
