The Short Form 36 was used to compare critically ill patients' premorb
id quality of life with normal values and investigate any changes foll
owing 6 months convalescence. One hundred and sixty-six survivors comp
leted the Short Form 36 at discharge from intensive care. The answers
given by survivors were significantly lower than normal for all dimens
ions. However, 21 patients who suffered from acute life-threatening co
nditions were identified and their overall scores were similar to norm
al values. After 6 months, 95 questionnaires were returned. Patients w
ho had suffered acute pathologies reported significant decreases in qu
ality of life whilst other patients with pre-existing ill health repor
ted significant improvement with reduced pain and better mental health
, vitality and social function. This study suggests that quality of li
fe of most patients admitted to intensive care is not as good as in th
e normal population but does not deteriorate except for those patients
admitted after acute life-threatening events.
