Simon Burns, minister for NHS finance and performance, said the figures came from an annual survey of IT investment in the NHS, which made up £1.3bn of the total.
The figure for capital expenditure came from NHS accounts and spending reported by foundation trusts, and totalled £261m, which included software licences.
The total IT spend in UK health is even greater, as the £1.6bn figure doesn't include spending by special health authorities and central spending by the Department of Health.
Spending under the National Programme for IT (NPfIT) makes up just over £1bn of the total £1.6bn spent.
Burns also revealed that in the financial year 2009-10 the NPfIT spent £322m on companies with headquarters outside the UK. The biggest beneficiary was CSC, whose contract was worth £213m last year. Fujitsu received £37m and Atos was paid £33m.
