The accuracy of capillary blood glucose monitoring has been well demonstrated when applied by patients in the outpatient setting or by specially trained nurses on inpatient diabetes units. In order to determine the applicability of this technique in the more general hospital setting, a program was initiated for instructing general staff nurses in the use of Chemstrips bG strips and the Accu-Chek bG meter. As a pilot study, nurses on four general medical and surgical hospital floors performed capillary glucose determinations within 15 minutes of the drawing of venous blood samples for determination of plasma glucose in the hospital's Chemistry Laboratory. Two hundred ten paired measurements were made by 31 nurses. Linear regression analysis yielded a Pearson correlation coefficient of 0.96 between bedside and laboratory glucose measurements. The mean percent deviation between the two values was 7.9 percent. Acceptance by both nurses and patients was high. Properly supervised capillary glucose monitoring can provide a valuable adjunct to the care of hospitalized patients with diabetes.
