Guided prescription of psychotropic medications for geriatric inpatients.

BACKGROUND: Inappropriate use or excessive dosing of psychotropic medications in the elderly is common and can lead to a variety of adverse drug events including falls, oversedation, and cognitive impairment. METHODS: We developed a database of psychotropic medication dosing and selection guidelines for elderly inpatients. We displayed these recommendations to physicians through a computerized order entry system at a tertiary care academic hospital. The system was activated for 2 of 4 six-week study periods in an off-on-off-on pattern. Main outcome measures were agreement with the recommended daily dose for the initial drug order, incidence of dosing at least 10-fold greater than the recommended daily dose, prescription of nonrecommended drugs, inpatient falls, altered mental status as measured by a brief nursing assessment, and hospital length of stay. RESULTS: A total of 7456 initial orders for psychotropic medications were prescribed for 3718 hospitalized elderly patients with a mean +/- SD age of 74.7 +/- 6.7 years. The intervention increased the prescription of the recommended daily dose (29% vs 19%; P<.001), reduced the incidence of 10-fold dosing (2.8% vs 5.0%; P<.001), and reduced the prescription of nonrecommended drugs (10.8% vs 7.6% of total orders; P<.001). Patients in the intervention cohort had a lower in-hospital fall rate (0.28 vs 0.64 falls per 100 patient-days; P = .001). No effect on hospital length of stay or days of altered mental status was found. CONCLUSION: A geriatric decision support system for psychotropic medications increased the prescription of recommended doses, reduced the prescription of nonrecommended drugs, and was associated with fewer inpatient falls.

Hetastarch and bleeding complications after coronary artery surgery.

STUDY OBJECTIVES: Controversy persists concerning the potential association between intraoperative use of hetastarch (ie, hydroxyethyl starch [HES]) and postoperative bleeding in patients undergoing surgery. To determine whether intraoperative HES use is associated with an increased risk of postoperative bleeding following coronary artery bypass graft (CABG) surgery. DESIGN: Case-control study. SETTING: A large academic medical center in the northeastern United States. PARTICIPANTS: A consecutive sample of 238 patients undergoing CABG surgery. MAIN OUTCOME MEASURES: Cases consisted of patients who had received either > or = 3 U packed RBCs, > or = 3 U platelets, > or= 3 U fresh frozen plasma, or any cryoprecipitate within 72 h after undergoing a CABG procedure, or who had undergone surgical revision for bleeding. All other CABG surgery patients served as control subjects. RESULTS: In multivariate models that controlled for a wide variety of demographic and clinical characteristics, we found that, compared to patients who did not receive any HES during surgery, those who received 1 U intraoperative HES had more than twice the risk of a bleeding outcome (odds ratio [OR], 2.32; 95% confidence interval [CI], 1.10 to 4.91), and those who received 2 or 3 U HES had more than four times the risk of postoperative bleeding (OR, 4.57; 95% CI, 1.74 to 12.00). CONCLUSIONS: HES use in patients undergoing CABG surgery may be associated with a significant risk of postoperative bleeding. A double-blinded, randomized, controlled trial will be necessary to confirm this finding.

Interactive voice response reminder effects on preventive service utilization.

This study evaluated the effects of interactive voice response (IVR) system reminders to managed care organization (MCO) members to obtain mammograms, Papanicolaou (Pap) tests, and influenza immunizations. The MCO identified 3 member cohorts and sent IVR reminders to get preventive services. Analyses employed claims data to examine relationships between IVR reminders and preventive service use 5 to 9 months post-intervention among members without prior utilization. Multivariate logistic regressions controlling for age, gender (for influenza immunizations), and risk stratum confirmed hypothesized relationships between intervention and preventive services: mammograms, odds ratio (OR) = 1.263 (95% confidence interval [CI] = 1.104, 1.444); Pap tests, OR = 1.241 (1.107, 1.391); influenza immunizations, OR = 2.072 (1.665, 2.580). IVR reminders are associated with higher rates of mammograms, Pap tests, and influenza immunizations. Study limitations include unknown generalizability of results and possible self-selection. There is justification for more IVR interventions and research to enhance MCO members' preventive service utilization.
