Lloyd George Envelope
General Practice records in the United Kingdom were traditionally paper-based. One very commonly encountered way of organising a patient's entire medical record was to place it in a buff-coloured, stiff card, 5 by 7 inch wallet known as a Lloyd-George Envelope.
The envelopes and the "continuation" cards which fit in them antedate the NHS, and were introduced as appurtenances to the insurance-based "panel" scheme introduced under Lloyd-George when he was secretary of state for health
In the 1960s, a move to A4 records was announced, and went about a quarter of the way to replacing them before foundering on a combination of underfunding, change of administrators, and inertia. The resulting record incompatibilities might have been good practice for the introduction of assorted proprietary computer record systems.
