Table 2.

All-cause mortality and hospitalization or all-cause mortality within a year in patients diagnosed with MRSA compared with matched patients free of MRSA from the GPRD (2001–2004) The hazard ratio is adjusted for all variables in Table 1. Death or hospitalization patients were followed until first event of either kind and only counted once.

Characteristic	n	Events	Person-years of follow-up	Rate of event per 100 years	Crude HR	Adjusted HR (95% CI)
Death
Patients with MRSA	1439	313	1224	25.6	4.85	4.08	(3.54–4.69)
Patients without MRSA	14,090	709	13510	5.2	1.00	1.00	(Reference)
Death or hospitalization
Patients with MRSA	1439	485	1106	43.9	3.93	3.31	(2.97–3.69)
