Impact of patient knowledge, patient-pharmacist relationship, and drug perceptions on adverse drug therapy outcomes

Abstract

The purpose of this project was to determine the relationship between adverse drug outcomes and knowledge of drugs, quality of a counseling relationship, and perceptions about drugs in an ambulatory clinic population. The presence of these three factors and other indicators of adverse outcomes were identified through a structured interview of 78 patients. Medical records were reviewed 3, 6, and 12 months after the initial interview to determine the presence of adverse drug outcomes. Four outcomes-hospitalizations, unscheduled clinic visits, emergency room visits, and changes in drug regimen-were assessed and categorized according to drug-related problem. Demographics of the group were recorded. Responses to the interview were analyzed to determine differences in counseling relationships between pharmacists and other health professionals. Logistic regression analysis was performed to determine the influence of independent variables on outcome. Relative risks for developing adverse outcomes given the presence of certain independent variables were calculated for significant associations. Significant relationships between predictor variables and adverse drug outcomes were identified for the following independent variables: female g...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
