SUMMARY This paper looks at two s u r v e y s of bed r e s t , conducted in a general hospital. The f i r s t s u r v e y , conducted early one a f t e r n o o n , assessed the prevalence of bed rest within the h o s p i t a l . It was found t h a t most of the patients (67 ~) were in bed, and nearly half of those (42 ~) were in bed for reasons other than being too sick or unsafe to be up, or because bed r e s t was part of t h e i r treatment. A second s u r v e y , in which a sample of general hospital patients was r e p e a t e d l y observed t h r o u g h o u t the d a y , found that patients with no r e q u i r e ments for bed rest spent 63 % (95 96 confidence limits: 51-75 96) of the active p a r t of the day in bed. It may be t h a t because of the n a t u r e of hospital design, many patients are unnecessarily confined to bed because t h e r e is simply nowhere else to go. I n a p p r o p r i a t e use of bed rest has implications for patient health and the utilization of scarce hospital resources. K e y w o r d s : bed rest in hospital,
