Comparative Study
Individual sulfonylureas and serious hypoglycemia in older people.
To compare the risk of serious hypoglycemia associated with the use of individual sulfonylureas in older people. ⋯ Significant differences in risk of serious hypoglycemia were observed among users of individual agents. This may be explained by duration, timing, or potency of hypoglycemic action. These data confirm previous findings that chlorpropamide use is associated with high risk of hypoglycemia and indicate that among second generation sulfonylureas, glipizide is less associated with hypoglycemia than is glyburide. More information comparing the effectiveness of glycemic control among individual sulfonylureas is needed to assist prescribers in selecting a specific agent for use in clinical practice.

To cross-validate the Delirium Rating Scale (DRS). ⋯ The DRS appears to a feasible instrument. In a sample with a high proportion of delirious patients, it has acceptable measurement properties when used by expert observers.

Patient preferences for life-sustaining treatment are frequently unknown at critical moments, which often results in clinicians providing treatment that is not medically indicated and/or may not be consistent with patient desires. A consortium of Oregon health care professionals developed the Medical Treatment Coversheet (MTC) to standardize documentation of patient preferences in the out-of-hospital setting by having corresponding physician orders available at the patient's location. We describe a unique process of development, evaluation, and implementation of the MTC. ⋯ We describe our process for development, initial evaluation, and implementation of the MTC. In clinical scenarios overall, the MTC improves the appropriateness of clinicians' decisions about life-sustaining treatments. We are planning statewide implementation of the MTC after appropriate education of clinicians.

Comparative Study
Medical screening of older drivers as a traffic safety measure--a comparative Finnish-Swedish evaluation study.
To evaluate the safety effect of age-related medical screening of older drivers by comparing the licensing laws and accident rates for older road users in Finland and Sweden. ⋯ We found no safety-related reasons to implement age-related medical screening of older drivers of the kind practiced in Finland. On the contrary, by producing a modal shift toward a more risky mode of travelling, this screening may indirectly lead to higher fatality rates among older road users.

To evaluate the clinical usefulness of Pepsinogen A (PGA) and C (PGC), PGA/PGC ratio, gastrin, and specific IgG anti-HP antibodies (anti-HP Ab) in monitoring the effect of cure for Helicobacter pylori (HP) infection in older people. ⋯ The eradication of HP from the stomach of older patients induces a rapid and significant decrease in serum levels of IgG anti-HP antibodies and PGC, with an increase in PGA/PGC ratio but not in gastrin. Unchanged serum levels of IgG anti-HP antibodies, PGC, and PGA/PGC ratio 2 months after completing HP eradication therapy are indicative of ongoing HP infection. The PGA/PGC ratio showed the best diagnostic accuracy among serum measures tested.
