Active Presecription Drug Safety Surveillance: Exploring Omop 2011-2012 Experiments, Susan Gruber, James M. Robins

Susan Gruber

The Observational Medical Outcomes Partnership (OMOP), a consortium of pharmaceutical, FDA, and academic researchers focuses on developing and evaluating electronic records-based methods for enhancing post-market drug safety surveillance. The OMOP 2011-2012 experiment consists of applying variants of seven analysis methods to five different EMR or claims databases to estimate the increase (decrease) in risk associated with drug-outcome pairs whose causal association has been previously established, and serves as a gold standard for comparison. Variants of each method can produce very different effect estimates, sometimes at odds with the gold standard. We explore the reasons behind this heterogeneity, and in doing …

Adverse Drug Events Post-Hospital Discharge In Older Patients: Types, Severity, And Involvement Of Beers Criteria Medications, Abir O. Kanaan, Jennifer L. Donovan, Nerissa P. Duchin, Terry S. Field, Jennifer Tjia, Sarah L. Cutrona, Shawn J. Gagne, Lawrence D. Garber, Peggy Preusse, Leslie R. Harrold, Jerry H. Gurwitz

Lawrence D. Garber

Objective: To characterize adverse drug events (ADEs) occurring within the high-risk 45-day period post-hospitalization in older adults.

Design: Clinical pharmacists reviewed the ambulatory records of 1000 consecutive discharges.

Setting: A large multispecialty group practice closely aligned with a Massachusetts-based health plan.

Participants: Hospitalized patients aged 65 years and older who were discharged to home.

Measurements: Possible drug-related incidents occurring during the 45-day period post-hospitalization were identified and presented to a pair of physician-reviewers who classified incidents as to whether an ADE was present, whether the event was preventable, and the severity of the event. Medications implicated in ADEs were further …

Dissemination Of Evidence-Based Atypical Antipsychotic Information To Nursing Homes, Celeste A. Lemay, Jennifer Tjia, Kathleen M. Mazor, Terry S. Field, Abir O. Kanaan, Jennifer L. Donovan, Jerry H. Gurwitz

Jennifer Tjia

Background: Accumulating evidence demonstrates minimal benefit and increased risk of off-label use of atypical antipsychotic medications for dementia-related behaviors. Optimal strategy for disseminating evidence-based guides to nursing home (NH) stakeholders is unclear. Our objective is to describe the impact of differing dissemination efforts in Connecticut NHs.

Methods: Forty-three Connecticut NHs were randomized to one of 3 arms receiving incrementally intensive dissemination strategies of the Agency for Healthcare Research and Quality Comparative Effectiveness Review Summary Guide on the off-label use of atypical antipsychotic drugs, which was included in a toolkit informed by a needs assessment of NHs. All NHs received the …

Antipsychotic Use Among Nursing Home Residents, Becky Briesacher, Jennifer Tjia, Terry Field, Daniel Peterson, Jerry Gurwitz

Jennifer Tjia

The prescribing of antipsychotic medications persists at high levels in US nursing homes (NHs) despite extensive data demonstrating marginal clinical benefits and serious adverse effects, including death.1- 2 However, imprecise and outdated data have limited the understanding of the current state of antipsychotic medication prescribing in NHs.3 We analyzed recent and detailed NH prescription data to address: (1) What is the current level of antipsychotic use? (2) Does antipsychotic use in NHs display geographic variation? and (3) Which antipsychotics are most commonly prescribed?

Studies To Reduce Unnecessary Medication Use In Frail Older Adults: A Systematic Review, Jennifer Tjia, Sarah Velten, Carole Parsons, Sruthi Valluri, Becky Briesacher

Jennifer Tjia

BACKGROUND: Overuse of unnecessary medications in frail older adults with limited life expectancy remains an understudied challenge.

OBJECTIVE: To identify intervention studies that reduced use of unnecessary medications in frail older adults. A secondary goal was to identify and review studies focusing on patients approaching end of life. We examined criteria for identifying unnecessary medications, intervention processes for medication reduction, and intervention effectiveness.

METHODS: A systematic review of English articles using MEDLINE, EMBASE, and International Pharmaceutical Abstracts from January 1966 to September 2012. Additional studies were identified by searching bibliographies. Search terms included prescription drugs, drug utilization, hospice or palliative …

Anatase Titanium Dioxide Coated Single Wall Carbon Nanotubes Manufactured By Sonochemical-Hydrothermal Technique, Paul Clemens, Xin Wei, Bobby L. Wilson, Renard L. Thomas

Renard L Thomas

A novel, cost effective, sonochemical-hydrothermal technique was used for the deposition of nanosized anatase titanium dioxide (TiO2) onto single wall carbon nanotubes (SWCNTs). This technique is described and the characterization of the synthesized TiO2-SWCNTs is reported. The characterization techniques employed include scanning electron microscopy (SEM), Raman spectroscopy, and X-ray diffraction (XRD). From the characterization the size and morphology of the synthesized TiO2 nanoparticles (deposited on the SWCNTs) are reported. Furthermore, it is demonstrated that the created TiO2 nanoparticles are chemically attached to the SWCNTs. Also, an important correlation between calculated TiO2 crystal size and the red shifts in the lowest …

Dementia And Risk Of Adverse Warfarin-Related Events In The Nursing Home Setting, Jennifer Tjia, Terry Field, Kathleen Mazor, Jennifer Donovan, Abir Kanaan, George Reed, Peter Doherty, Leslie Harrold, Jerry Gurwitz

Jennifer Tjia

BACKGROUND: Little attention has been focused on the safety of medications administered to treat non illnesses in nursing home residents with dementia. It is unclear whether this population is at increased risk of adverse drug events. OBJECTIVES: To test the hypotheses that in nursing home residents with dementia prescribed warfarin have less time in therapeutic range and a higher incidence of nonpreventable and preventable adverse warfarin events compared to nursing home residents without dementia after controlling for facility and patient characteristics. METHODS: A prospective cohort embedded in a clinical trial of nursing home residents prescribed warfarin in 26 nursing homes …
