Level and variation on quality of care in China: a cross-sectional study for the acute myocardial infarction patients in tertiary hospitals in Beijing

Table 2 Level of QoC for all hospitals

Measures	No. of cases with complete information	Recommended care delivered or adverse outcome N (%)	No. of missing data	P value*
Aspirin at arrival	1139	1075 (94.38)	89	<0.001
Aspirin prescribed at discharge	1176	1142 (91.11)	52	0.577
Beta-blocker prescribed at discharge	1175	982 (83.75)	53	<0.001
Statin prescribed at discharge	1176	1134 (96.43)	52	0.070
ACEI or ARB for LVSD	54	34 (62.96)	N/A	N/A
PCI received within 90 min of hospital arrival	357	171 (47.90)	N/A	<0.001

ACEI = angiotensin-converting enzyme inhibitors, ARB = angiotensin receptor blockers, LVSD = left ventricular systolic dysfunction, PCI = percutaneous coronary intervention, N/A = not applicable
*P value tests the hypothesis that there are no differences in quality of care between the 14 hospitals
