The antiretrovirals in pregnancy registry: a fifteenth anniversary celebration.

UNLABELLED: The year 2007 marks the fifteenth anniversary year of the founding of a landmark effort in drug safety risk management, the formation of the first monitoring effort of an antiretroviral (ARV) drug in pregnancy which has become the Antiretrovirals in Pregnancy Registry, the APR. This multicompany, multi-national voluntary collaborative registry monitors pregnancy exposure to a class of highly important drugs for any indication of an increase in the postexposure incidence of birth defects in the offspring of these pregnancies. To recognize the anniversary, the Steering Committee of the APR has commissioned this review of the contributions and lessons learned over the past decade and a half and, in the spirit of continuous process improvement, has committed to apply these lessons for the next fifteen years. This retrospective examines the antecedents to this registry and the context in which the APR was formed; the early efforts to establish technical and organizational procedures and policies; the evolving experiences with enrollment and follow-up, patient and participant protections, information management and oversight; public and regulatory dissemination; and of course, the accomplishments and lessons learned. TARGET AUDIENCE: Obstetricians & Gynecologists, Family Physicians. LEARNING OBJECTIVES: After completion of this article, the reader should be able to explain the value of a drug registry in determining safety risk management; summarize that the Antiretroviral (ARV) drugs in Pregnancy Registry (APR) is a very successful multinational, multicompany collaborative effort that has been in place for 15 years; and state that it has been an ideal public interest effort dealing with the devastating pandemic of human immunodeficiency viral disease.

Literacy and misunderstanding prescription drug labels.

BACKGROUND: Health literacy has increasingly been viewed as a patient safety issue and may contribute to medication errors. OBJECTIVE: To examine patients' abilities to understand and demonstrate instructions found on container labels of common prescription medications. DESIGN: Cross-sectional study using in-person, structured interviews. SETTING: 3 primary care clinics serving mostly indigent populations in Shreveport, Louisiana; Jackson, Michigan; and Chicago, Illinois. PATIENTS: 395 English-speaking adults waiting to see their providers. MEASUREMENT: Correct understanding of instructions on 5 container labels; demonstration of 1 label's dosage instructions. RESULTS: Correct understanding of the 5 labels ranged from 67.1% to 91.1%. Patients reading at or below the sixth-grade level (low literacy) were less able to understand all 5 label instructions. Although 70.7% of patients with low literacy correctly stated the instructions, "Take two tablets by mouth twice daily," only 34.7% could demonstrate the number of pills to be taken daily. After potential confounding variables were controlled for, low (adjusted relative risk, 2.32 [95% CI, 1.26 to 4.28]) and marginal (adjusted relative risk, 1.94 [CI, 1.14 to 3.27]) literacy were significantly associated with misunderstanding. Taking a greater number of prescription medications was also statistically significantly associated with misunderstanding (adjusted relative risk, 2.98 [CI, 1.40 to 6.34] for > or =5 medications). LIMITATIONS: The study sample was at high risk for poor health literacy and outcomes. Most participants were women, and all spoke English. The authors did not examine the association between misunderstanding and medication error or evaluate patients' actual prescription drug-taking behaviors. CONCLUSIONS: Lower literacy and a greater number of prescription medications were independently associated with misunderstanding the instructions on prescription medication labels.

Misunderstanding of prescription drug warning labels among patients with low literacy.

PURPOSE: The common causes for misunderstanding prescription drug warning labels (PWLs) among adults with low literacy were studied. METHODS: A total of 74 patients reading at or below the sixth-grade level and receiving care at the primary care clinic at the Louisiana State University Health Sciences Center in Shreveport were recruited to participate in structured interviews. Patients were asked to interpret and comment on eight commonly used warning labels found on prescription medications. Correct interpretation was determined by expert panel review of patients' verbatim responses. Qualitative methods were employed to code responses and generate themes regarding the misunderstanding of these PWLs. RESULTS: Among this sample of patients with low literacy skills, rates of correct interpretation for the eight warning labels ranged from 0% to 78.7%. With the exception of the most basic label, less than half of all patients were able to provide adequate interpretations of the warning label messages. Five themes were derived to describe the common causes for misunderstanding the labels: single-step versus multiple-step instructions, reading difficulty of text, use of icons, use of color, and message clarity. Labels were at greater risk for being misunderstood if they included multiple instructions, had a greater reading difficulty, included unfamiliar terms, or used confusing icons that were discordant with text messages. Participants also frequently imposed an incorrect meaning on label colors, which led to further confusion. CONCLUSION: Patients with low literacy skills demonstrated a lower rate of correct interpretation of the eight most commonly used PWLs than did those with higher literacy skills. Multiple-step instructions, reading difficulty of text, the use of icons, the use of color, and message clarity were the common causes of label misinterpretation.

Defining the competencies of those conducting pharmacovigilance.

PURPOSE: The absence of agreed competencies in pharmacovigilance and patient risk management is a key factor hindering the development of training and a curriculum in these interrelated disciplines. If competencies were to be developed, they could be tailored to the different roles and responsibilities of the various staff involved. PROPOSAL: We describe a simple theoretical model of functional and behavioural competencies that is based on an organisation with three levels of staff: evidence collectors and gatherers, evidence processors and distillers, and decision makers. CONCLUSIONS: To stimulate discussion about how to enhance the progress already being made in pharmacovigilance and patient risk management, we have proposed functional and behavioural competencies for pharmacovigilance as a way of identifying and measuring scientific and personal skills pertinent to pharmacovigilance. Competencies should, we believe, be agreed and adopted by all those seeking to improve pharmacovigilance. We invite discussion of these proposals.

Growing the field of health impact assessment in the United States: an agenda for research and practice.

Health impact assessment (HIA) methods are used to evaluate the impact on health of policies and projects in community design, transportation planning, and other areas outside traditional public health concerns. At an October 2004 workshop, domestic and international experts explored issues associated with advancing the use of HIA methods by local health departments, planning commissions, and other decisionmakers in the United States. Workshop participants recommended conducting pilot tests of existing HIA tools, developing a database of health impacts of common projects and policies, developing resources for HIA use, building workforce capacity to conduct HIAs, and evaluating HIAs. HIA methods can influence decisionmakers to adjust policies and projects to maximize benefits and minimize harm to the public's health.

Breaking the translational barriers: the value of integrating biomedical informatics and translational research.

The conduct of translational health research has become a vital national enterprise. However, multiple barriers prevent the effective translation of basic science discoveries into clinical and community practice. New information technology (IT) applications could help address these barriers. Unfortunately, owing to a combination of organizational, technical, and social factors, neither physician-investigators and research staff nor their clinical and community counterparts have harnessed such applications. Recently, at the request of the Institute of Medicine's Clinical Research Roundtable, a qualitative study of these factors was conducted at several leading academic medical centers. We explore the current status of IT in the translational research domain, describe the qualitative results, and conclude with a proposed set of initiatives to further increase the integration of IT into translational research.

The impact of community design and land-use choices on public health: a scientific research agenda.

The design of a community's built environment influences the physical and mental health of its residents. Because few studies have investigated this relationship, the Centers for Disease Control and Prevention hosted a workshop in May 2002 to help develop a scientific research agenda on these issues. Workshop participants' areas of expertise included physical activity, injury prevention, air pollution, water quality, urban planning, transportation, architecture, epidemiology, land use, mental health, social capital, housing, and social marketing. This report describes the 37 questions in the resulting research agenda. The next steps are to define priorities and obtain resources. The proposed research will help identify the best practices for designing new communities and revitalizing old ones in ways that promote physical and mental health.

Use of national public health performance standards to assess Maine's diabetes system.

In the fall of 2003, Maine underwent a rigorous assessment of the diabetes public health system using a modified version of the State Public Health System Performance Instrument developed by the Centers for Disease Control and Prevention's National Public Health Performance Standards Program and other national partners. The assessment was intended to serve as the impetus for the development of a statewide improvement plan. This article details the assessment process and provides a case study highlighting the successful application of systems-based model standards for a categorical issue.

The public health workforce.

Defining the public health workforce and specifying its performance requirements present equal challenges as the nation anticipates public health needs for the twenty-first century. The core group of professionals employed by government public health agencies works in close partnership with a wide range of public, private, and voluntary organizations. The wider circle includes almost all physicians, dentists, and nurses, plus many other health, environmental, and public safety professionals. The task of ensuring that this workforce is prepared with skills and knowledge to face both identified and emerging public health challenges is immense.

Spending on postapproval drug safety.

Withdrawals of high-profile pharmaceuticals have focused attention on post-approval safety surveillance. There have been no systematic assessments of spending on postapproval safety. We surveyed drug manufacturers regarding safety efforts. Mean spending on postapproval safety per company in 2003 was 56 million dollars (0.3 percent of sales). Assuming a constant safety-to-sales ratio, we estimated that total spending on postapproval safety by the top twenty drug manufacturers was 800 million dollars in 2003. We also examined, using regression analysis, the relationship between the number of safety personnel and the number of initial adverse-event reports. This study offers information for the debate on proposed changes to safety surveillance.
