To evaluate associations among hospital characteristics, staffing levels of health care professionals, and mortality rates in 3763 United States hospitals, a data base was constructed from the American Hospital Association's Abridged Guide to the Health Care Field and hospital Medicare mortality rates from the Health Care Financing Administration. A multivariate regression analysis controlling for severity of illness was employed to determine the associations. Hospital characteristics associated with lower mortality were occupancy rate and private nonprofit and private for-profit ownership. Mortality rates decreased as staffing level per occupied bed increased for medical residents, registered nurses, registered pharmacists, medical technologists, and total hospital personnel. Mortality rates increased as staffing level per occupied bed increased for hospital administrators and licensed practical-vocational nurses. To our knowledge, this is the first study to show that pharmacists were associated with lower mortality rates.
Valproic acid (VPA) may cause impaired platelet function, thrombocytopenia and, occasionally, severe bleeding. Controversy exists both as to the mechanism of this alteration in hemostasis and as to whether these adverse effects are either dose-related or idiosyncratic. Previous investigations have focused primarily on pediatric patients who commonly were receiving multiple anticonvulsant medications. We evaluated a cohort of 27 adult patients with epilepsy who were receiving VPA monotherapy and compared them with age-matched controls to determine whether a correlation exists between platelet count, function, bleeding time, levels of von Willebrand's factor antigen, and VPA dose or plasma concentration. VPA patients had significantly lower platelet counts and longer bleeding times than did controls (p < 0.05). Platelet count was inversely correlated to VPA dose and both free and total VPA concentration (p < 0.01). There was no significant difference in levels of von Willebrand's factor antigen between patients and controls. We assessed platelet aggregation by measurement of whole-blood platelet aggregation and release with agonists including adenosine diphosphate, thrombin, collagen, arachidonic acid, and ristocetin. VPA patients had significant decreases in platelet aggregation values compared with controls. There were significant differences in collagen, arachidonic acid, and adenosine diphosphate release and aggregation between groups that correlated to both VPA dose (p < 0.01) and concentration (p < 0.05). Prolongation of bleeding time was significantly correlated to both VPA dose and concentration. Our data suggest a significant relationship between impaired platelet function and both VPA dose and plasma concentration.
Objective. To develop, implement, and assess the effectiveness of an online medication therapy management (MTM) program to train pharmacists and pharmacy students in providing MTM services for patients with diabetes and to increase their intent to perform these services.Design. An online program was created using an Internet-based learning platform to simulate 4 MTM meetings between a pharmacist and a virtual patient diagnosed with diabetes. Assessment. Eighty students and 42 pharmacists completed the program. After completing the program, scores on post-intervention assessments showed significant improvement in 2 areas: control over performing MTM, and knowledge of how to perform MTM. Students had a significantly less-positive attitude about MTM and a decline in their perception of the social expectation that MTM is part of the practice of pharmacy, while pharmacists' attitudes did not change significantly in these areas. Conclusion. This online program using a virtual patient improved both participants' belief that they have control over performing MTM, and their knowledge of how to perform MTM for diabetic patients, which may increase the likelihood that pharmacists and pharmacy students will perform MTM in the future.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
