What was your question again? The perils of using observational data to answer questions other than the one you wish to ask.
Miguel Hernán, MD, MPH, ScM, DrPH
Associate Professor of Epidemiology
Harvard School of Public Health
SEMINAR DESCRIPTION:
Observational studies are often used to make causal inferences. However, in the absence of well-defined causal questions, it is difficult to assess the validity and implications of a particular analysis of observational data. This problem is more severe when estimating effects from complex longitudinal data with time-varying treatments as is common in pharmacoepidemiology.

*Special Presentation*
Community-based surveillance of antimicrobial use in resource-constrained settings
Dr. Anita Kotwani
Associate Professor
Department of Pharmacology
Vallabhbhai Patel Chest Institute
University of Delhi
Delhi, India
SEMINAR DESCRIPTION:
Antimicrobial resistance in microorganisms is a major public health problem worldwide. The increased resistance is a result of many factors, but the foremost cause is the overall volume of antibiotic consumption, particularly for indications that do not require such therapy. Enhanced antimicrobial surveillance is one of the strategies to control antimicrobial overuse or misuse in the community. In a number of developed countries, extensive surveillance programmes have been developed to study patterns of antimicrobial resistance and antibiotic use. However, the problem of antimicrobial resistance has received relatively little recognition in developing countries and the ability to undertake extensive surveillance is lacking in resource-constrained countries. There is a lack of community-based databases on antimicrobial resistance and antibiotic use in developing countries. WHO collaborated and funded five pilot projects, three in India and two in South Africa (2002-2005) for developing validated reproducible and sustainable surveillance methodologies to quantify antimicrobial resistance and antibiotic use in the community. The pilot project conducted in New Delhi, India utilized a methodology that monitored antimicrobial use in the community through patient exit interviews at private retail pharmacies. The second phase of surveillance (2007-2008) expanded the established methodology at three types of facilities: private retail pharmacies, public sector facilities, and private clinics. Antibiotic use was measured as daily
defined dose (DDD)/1000 patients visiting the facility and also as percent of patients receiving an antibiotic. 39% of the patients who visited during data collection period had encountered with at least one antibiotic in public sector and at private retail pharmacies whereas 43% of patients visiting private clinics were prescribed antibiotics. Methodology established and trend and pattern of antibiotic use observed in the community will be discussed.

Wireless adherence monitoring for antiretroviral therapy in resource limited settings
Jessica Haberer, MD, MS
Research Scientist, Harvard Initiative for Global Health
Assistant in Health Decision Sciences, Massachusetts General Hospital
Instructor, Harvard Medical School
SEMINAR DESCRIPTION:
HIV antiretroviral therapy adherence is tightly linked to viral suppression and drug resistance. Current adherence monitoring strategies detect missed doses several weeks to months after they occur and are unable to direct adherence interventions before virologic failure develops. Novel approaches are needed to prevent drug resistance and the loss of treatment effectiveness. Dr. Jessica Haberer will discuss the use of cell phone technology, including interactive voice response and short message service, as well as a wireless adherence device called Wisepill, for real-time adherence monitoring in resource limited settings. She will review the current use, advantages, and disadvantages of each technology, as well as present preliminary data from her research group in Mbarara, Uganda.

Using technology to facilitate family and friend support for medication use in adults with chronic kidney disease
Ashley J. Beard, PhD
Fellow in Pharmaceutical Policy Research, DPM
Harvard Medical School and Harvard Pilgrim Health Care Institute
SEMINAR DESCRIPTION:
Over 16 million Americans have mild to moderate chronic kidney disease (CKD). Patients with CKD are at increased risk for cardiovascular disease, kidney failure, and other serious and costly complications. In response to the increasing prevalence and impact of CKD, reducing the rates and complications of CKD is one of the goals of Healthy People 2010. Appropriate medication use in patients with early stage CKD can slow the progression to end-stage renal disease. Yet, consistent, appropriate medication use can be a challenge for adults with CKD. Patients with CKD may have other chronic conditions, take a number of medications, and lack social support for treatment adherence. Informal support from family and friends may be important for patient medication management but much still remains unknown about such support and how to best promote it. Innovations in use of communication technologies show promise for facilitating social support and improving patient disease management but need further evaluation. In collaboration with a local, private health technology company and Harvard Pilgrim Health Care (HPHC), we are conducting a pilot randomized controlled-trial (RCT). Our aims are to better understand medication use in patients with CKD, barriers to medication use, and to evaluate an innovative, communication technology-driven intervention that engages friends and family to improve patient medication use. Details of the intervention, study design, and progress and challenges to date will be discussed.

The Path From Research-Based Interventions to Policies Aimed at Improving Prescribing Practices in Family Medicine Clinics
Ricardo Pérez-Cuevas, MD, MSc, MHS, DrPH
Epidemiology and Health Services Research Unit
Mexican Institute of Social Security (IMSS), Mexico
SEMINAR DESCRIPTION:
The ongoing epidemiological changes that result in an increase of chronic conditions such as diabetes and hypertension and the substandard performance to care for the most common diseases in family medicine settings have prompted to look for evidence-based interventions that help to tackle these problems and to improve institutional performance.
The presentation addresses the progress made in the Mexican Social Security System Health Insurance Program (IMSS) (which covers about 45 million individuals) from research-based multifaceted continuing medical education interventions aimed at improving family doctors’ prescribing practices to large-scale multidimensional education and feedback programs. The results of small-scale research projects encouraged decision-makers to implement and evaluate large-scale comprehensive programs as part of the efforts to build the institutional capacity to improve quality and allowed the design and implementation of quality of care indicators.
In addition, the presentation describes ongoing research projects to improve prescribing practices and quality of care through innovative tools that take advantage of the IMSS electronic medical record and the institutional health information system. These tools will allow evaluating prescribing practices, providing feedback to family doctors about their performance and implementing efficient and effective continuing medical education activities.

High deductible health plans and the cost and utilization of maternity care services
Katy Backes Kozhimannil, PhD, MPA
Research Fellow, Department of Population Medicine
Harvard Medical School and Harvard Pilgrim Health Care Institute
SEMINAR DESCRIPTION:
Childbirth is the leading reason for hospitalization in the United
States, and maternity care comprises a major expenditure for many
American families and health insurance programs. The rapid growth of
high deductible health plans may impact out-of-pocket costs and
quality of maternity care. This study uses a pre/post study design
with a control group and a difference-in-differences analysis to
examine the effect of an employer-mandated insurance transition on
total costs (sum of expenditures by insurer and member) and
out-of-pocket costs (member copayment and deductible expenditures) for
maternity and delivery care, and also utilization of prenatal,
delivery, and postpartum services.

International Perspectives on Adherence and Resistance to HIV Antiretroviral Therapy
David Bangsberg, MD, MPH
Director MGH Center for Global Health
Harvard Medical School
SEMINAR DESCRIPTION:
Public health debates about providing HIV antiretroviral therapy to impoverished HIV+ populations are based on the relationship between adherence and risk of drug resistance to HIV antiretroviral therapy. Early justifications for withholding antiretroviral therapy from marginalized domestic populations, such as drug users and the homeless, were mistaken for two reasons. First, levels of adherence in marginalized populations were not much different than the general HIV+ population, and second, early single protease-based antiretroviral therapy lead to drug resistance predominately in highly (80-95%) adherent individuals. In retrospect, HIV antiretroviral drug resistance during the first decade of effective therapy was not driven by poor adherence, but rather by the fact that early regimens were not potent enough to fully suppress the virus in patients who took most, if not all, of their medications. The introduction of more potent ritonavir-boosted protease inhibitor and non-nucleoside reverse transcriptase inhibitor regimens have shifted this relationship towards full viral suppression and cessation of drug resistance at high levels of adherence.
Similar concerns slowed the provision of HIV antiretroviral therapy in resource-limited settings based on the expectations that extreme poverty would lead to poor adherence and the global spread drug resistant virus. Data from most studies indicate that these concerns were overstated. Individuals in resource-limited settings consistently take >90% of their medication, compared to 70% in resource-rich settings. Furthermore, full viral suppression is possible in antiretroviral naïve patients on non-nucleoside reverse transcriptase inhibitors regimens, typical of resource-limited settings, at moderate levels of adherence. Rather, the risk of drug resistance in resource-limited settings appears to be more related interruptions in therapy due to structural and financial barriers to drug supply and distribution. These interruptions in therapy lead to nevirapine monotherapy as nucleoside antiretroviral drug levels (stavudine and lamivudine) decay more rapidly than non-nucleoside reverse transcriptase inhibitor drug levels (nevirapine) following a treatment interruption (“the nevirapine tail”). The sensitivity to treatment interruptions in resource-limited settings may be further accentuated by ethnic pharmacogenomic differences in drug metabolism, leading to more extended periods of nevirapine monotherapy during an interruption. While efforts to sustain and prevent declines in adherence will be important in resource-limited settings, resistance will have less to do with forgotten doses, than ensuring a reliable drug supply and distribution system.
