The Medication Regimen of Patients With Heart Failure: The Gerontologic Considerations and Anticholinergic Burden: A Mixed-Methods Study.

Background: Although prescription medication adherence has been studied in the population living with heart failure (HF), little attention has focused on the patient's overall medication practices including over-the-counter medications. Patients with HF live with the certainty that their quality of life depends on the proper management of multiple medications. Failure to properly manage prescription medications increases the risk of exacerbation of HF and increased rates of rehospitalization.

Concurrent use of amphetamine stimulants and antidepressants by undergraduate students.

Undergraduate students were recruited to participate in an online survey to report their use of amphetamine stimulants and other drugs. Significant differences were found between students reporting (n=79; 4.0%) and not reporting (n=1,897; 96%) amphetamine-stimulant use in the past month - in terms of race/ethnicity, class standing, residence, health symptoms, self-health report - in addition to alcohol, tobacco, pain-reliever, and antidepressant use.

Promoting safe and effective use of OTC medications: CHPA-GSA National Summit.

Research on the ways older people use prescription medications (Rx) is a mainstay of the gerontological literature because use of Rx medications is common, and appropriate use is central to effective management of chronic disease. But older adults are also major consumers of over-the-counter (OTC) medications, which can be equally significant for self-care. Nearly half of older adults aged 75-85, for example, are regular users of an OTC product.

Reducing Adverse Self-Medication Behaviors in Older Adults with Hypertension: Results of an e-health Clinical Efficacy Trial.

A randomized controlled efficacy trial targeting older adults with hypertension (age 60 and over) provided an e-health, tailored intervention with the "next generation" of the Personal Education Program (PEP-NG). Eleven primary care practices with advanced practice registered nurse (APRN) providers participated. Participants (N = 160) were randomly assigned by the PEP-NG (accessed via a wireless touchscreen tablet computer) to either control (entailing data collection and four routine APRN visits) or tailored intervention (involving PEP-NG intervention and four focused APRN visits) group.

Psychometrics of the computer-based Relationships with Health Care Provider Scale in older adults.

The type and quality of the provider-patient health care relationship impacts patient adherence. The study purpose was to convert the 5-item paper and pencil Relationships With Health Care Provider Scale (RHCPS) to a reliable and valid computer-based scale for use with older adults. Outpatient adults (N = 121) older than 59 years were recruited.

A Qualitative Study of Older Adults and Computer Use for Health Education: "It opens people's eyes".

Adults over the age of 60 struggle with achieving target blood pressure readings due to difficulties seeing, hearing and understanding medical information which can result in poor adherence and drug interactions that can be fatal. According to the Institute of Medicine (2000) approximately 10% of adverse drug events may be attributed to communication failure between the provider and patient. Informing patients of potential drug interactions with over-the-counter (OTC) medications, supplements and alcohol use can contribute to better blood pressure control.

Genetic polymorphism in paraoxonase 1 (PON1): Population distribution of PON1 activity.

Paraoxonase-1 (PON1) is a serum esterase that hydrolyzes the activated oxon form of several organophosphates. The central role of PON1 in detoxification of organophosphate (OP) pesticides was demonstrated in knockout mouse studies, suggesting that human variability in PON1 needs to be considered in health risk assessments involving exposure to these pesticides. The current analysis focused on two genetic loci in which polymorphisms demonstrated to affect PON1 activity.

Genetic polymorphism in cytochrome P450 2D6 (CYP2D6): Population distribution of CYP2D6 activity.

Cytochrome P-450 2D6 (CYP2D6) is involved in the metabolism of many therapeutic drugs even though the enzyme represents a small proportion of the total CYP content of human liver. In vivo phenotyping with probe drug substrates such as debrisoquine and dextromethorphan showed a clear separation between poor metabolizers (PM) and extensive metabolizers (EM). This polymorphism may affect susceptibility to environmental disease, as suggested by molecular epidemiologic studies that found an association between CYP2D6 metabolizer phenotype and cancer risk; however, this association is not consistent.

The influence of genetic polymorphisms on population variability in six xenobiotic-metabolizing enzymes.

This review provides variability statistics for polymorphic enzymes that are involved in the metabolism of xenobiotics. Six enzymes were evaluated: cytochrome P-450 (CYP) 2D6, CYP2E1, aldehyde dehydrogenase-2 (ALDH2), paraoxonase (PON1), glutathione transferases (GSTM1, GSTT1, and GSTP1), and N-acetyltransferases (NAT1 and NAT2). The polymorphisms were characterized with respect to (1) number and type of variants, (2) effects of polymorphisms on enzyme function, and (3) frequency of genotypes within specified human populations.

Reducing adverse self-medication behaviors in older adults with the Next Generation Personal Education Program (PEP-NG): Design and methodology.

A randomized controlled efficacy trial targeting older adults with hypertension is providing a tailored education intervention with a Next Generation Personal Education Program (PEP-NG) in primary care practices in New England. Ten participating advanced practice registered nurses (APRNs) completed online knowledge and self-efficacy measures pre-onsite training and twice more after completing a continuing education program. Patient participants self-refer in response to study recruitment brochures and posters.

Advanced practice registered nurse usability testing of a tailored computer-mediated health communication program.

This study tested the usability of a touch-screen-enabled Personal Education Program with advanced practice RNs. The Personal Education Program is designed to enhance medication adherence and reduce adverse self-medication behaviors in older adults with hypertension. An iterative research process was used, which involved the use of (1) pretrial focus groups to guide the design of system information architecture, (2) two different cycles of think-aloud trials to test the software interface, and (3) post-trial focus groups to gather feedback on the think-aloud studies.

A pilot program at the worksite to reduce adverse self-medication behaviors.

A Next Generation Personal Education Program (PEP-NG) that captures self-reported medication behaviors and delivers a tailored educational intervention on a touchscreen interface was piloted with 11 adults with hypertension, aged 45-60 years, in a worksite setting. A time series design with multiple institution of treatment (four visits over three months) was employed. Blood pressure (BP), self-medication behaviors, self-efficacy, and knowledge for avoiding adverse self-medication behaviors were assessed at each of four visits.

Usability testing by older adults of a computer-mediated health communication program.

Failure to adhere to an antihypertensive regimen and interactions between antihypertensives and other medicines represent serious health threats to older adults. This study tested the usability of a touch-screen-enabled personal education program (PEP). Findings showed that older adults rated the PEP system usability, system usefulness, and system-use satisfaction at a moderately high level for prototype-1 and at an exceptionally high level for prototype-2.

Beta testing of a network-based health literacy program tailored for older adults with hypertension.

A touch screen-enabled "Personal Education Program" was modified to the "next generation" to capture self-medication behaviors of older adults with hypertension and assess related knowledge and self-efficacy. The program analyzes patient-entered information and delivers interactive educational content tailored to the reported behaviors. Summaries of self-reported symptoms, medication use (including frequency/time), drug interactions, and corrective strategies with an illustration of the drug interaction are printed to inform the provider before the primary care visit and for the patient to take home for self-study.
