Drug prescriptions: Adherence and understanding in Madagascar

Abstract

Frequently ignored or neglected, poor adherence is an important cause of treatment failure and a major public health problem. We assessed the factors involved in adherence in a hospital in Madagascar. This long-term study evaluated two groups of variables: patients' level of understanding of their disease and drug prescriptions, and the information on the prescription written by the doctor. We interviewed 93 in-patients (mean age: 50 years) and found that 16% were illiterate. Overall, 27% did not know the name of their illness, 34% were unaware of the treatment objectives, and 14% did not understand the drug prescription. On 20% of the prescriptions, the patients' name was not included, and the daily dose information and schedule was omitted from 16%. A day after receiving the prescription, only 64% had purchased the medication and only 53% of all patients had taken any. A correlation was observed between illiteracy, knowledge of the disease/treatment goals, and non-purchase of drugs. The poor quality of information contained in the prescriptions and patients' poor understanding of what they were supposed to do are obvious. Using pre-completed health forms and text messages might improve adherence.

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.
