[1] There were 95 HAs at the time of their abolition in England in 2002, and they reported to the eight regional offices of the NHS Executive.
The HAs were divided into a total of 22 local health groups (LHGs), one in each of the Welsh unitary authorities.
However, by 2002, a significant number had converted to primary care trusts (PCTs).
Their functions were mostly taken up by 300 PCTs, and 28 strategic health authorities (SHAs) were established (which were reduced in number to 10 in 2006).
[4][5] There were originally separate authorities for Barnet and Enfield & Haringey, for Bexley & Greenwich and Bromley, for East & North Hertfordshire and South Hertfordshire, and for the Isle of Wight & Portsmouth and South-East Hampshire.
