Iodinated contrast prior to thrombolysis was not associated with worse intracranial hemorrhage.
The investigators' objective was to assess relative incidence of clinical adverse effects between patients receiving, and not receiving, iodinated contrast prior to thrombolysis. They found that no consistent harms were observed in association with intravenous iodinated contrast prior to recombinant tissue-type plasminogen activator administration, concluding that it is reasonable to continue computed tomographic angiography prior to thrombolysis as clinically indicated.

Benzodiazepine use in the United States.
This study provides the first estimates of the annual prevalence of benzodiazepine use in the United States and examines variation in rates of benzodiazepine use by age. In 2008, approximately 5.2 percent of US adults aged 18 to 80 years used benzodiazepines. The percentage who used benzodiazepines increased with age from 2.6 percent (18-35 years) to 5.4 percent (36-50 years) to 7.4 percent (51-64 years) to 8.7 percent (65-80 years).

Prevalence and characteristics of medication sharing behavior in a pediatric Medicaid population with asthma.
The researchers described features surrounding the sharing and borrowing of nonprescription medications and examine the effects of this behavior on adverse asthma outcomes among children with asthma. They found a trend toward decreased Asthma Control Test (ACT) score and a higher proportion of patients with ACT scores of 19 or lower among those who shared or borrowed medication.

Epidemiology of drug-disease interactions in older veteran nursing home residents.
The objective of this study was to assess the prevalence of and factors associated with potentially inappropriate drug– disease combinations according to the AGS 2012 Beers criteria that are clinically important in elderly adults residing in Veterans Affairs Community Living Centers. It found that drug-disease interactions were common in older residents with dementia or cognitive impairment or a history of falls or hip fracture.

High override rate for opioid drug-allergy interaction alerts: current trends and recommendations for future.
This paper examined trends in drug-allergy interaction (DAI) alert overrides for opioid medications - the most commonly triggered alerts in the computerized provider order entry (CPOE). Allergic reactions included a high proportion of non-immune mediated opioid reactions. The DAI alert override rate was high for immune-mediated and life-threatening reactions. Exact allergy-medication matches were overridden less frequently compared to non-exact matches within allergy groups.

Predictors of antiemetic alteration in pediatric acute myeloid leukemia.
The purpose of this study was to gain better knowledge of patient and cancer treatment factors associated with nausea/vomiting (NV) in order to enhance prophylaxis in children being treated for acute myeloid leukemia (AML). It found that treatment-related NV, as evidenced by antiemetic alterations, is more prevalent with increasing age.

Predictors of medication-related problems among Medicaid patients participating in a pharmacist-provided telephonic medication therapy management program.
The objective of this study was to identify predictors of medication-related problems (MRPs) among Medicaid patients participating in a telephonic medication therapy management (MTM) program. The analysis of study results supports the relative importance of number of medications as a predictor of MRPs in the Medicaid population and identifies other predictors.

Computerised provider order entry combined with clinical decision support systems to improve medication safety: a narrative review.
The authors searched AHRQ's Patient Safety Net to identify reviews of the effect of computerised provider order entry (CPOE) combined with clinical decision support systems (CDSS) on adverse drug event (ADE) rates in inpatient and outpatient settings. They found that CPOE+CDSS was consistently reported to reduce prescribing errors, but does not appear to prevent clinical ADEs in either the inpatient or outpatient setting. Implementation of CPOE+CDSS profoundly changes staff workflow, often leading to unintended consequences and new safety issues (such as alert fatigue) which limit the system's safety effects.

Optimal matching ratios in drug safety surveillance.
The researchers used a simulation design to generate 48 scenarios varying in the baseline outcome rate, proportion of exposed, true effect size (without effect modification), and strength of unmeasured residual confounding. They found that except for the most extreme combination of rare outcome and exposure, in scenarios with no residual confounding, 1:1 matching removed 98% to 99% of the bias.

Reducing contrast-induced acute kidney injury using a regional multicenter quality improvement intervention.
The researchers sought to determine whether a 6-year regional multicenter quality improvement intervention could reduce contrast-induced acute kidney injury (CI-AKI) after percutaneous coronary interventions. They found that benchmark hospitals had no significant changes in CI-AKI, while rates of CI-AKI were significantly reduced in hospitals receiving the intervention. Key qualitative system factors associated with improvement included multidisciplinary teams, limiting contrast volume, standardized fluid orders, intravenous fluid bolus, and patient education about oral hydration.

Medication safety after implementation of a commercial electronic health record system in five safety-net practices: a mixed methods approach.
This study, conducted in five safety-net practices, examined the impact of implementing a commercial electronic health records system on medication safety. The authors found 130 "true" drug-drug interaction (DDI) pairs, representing 149,087 visits and 62 providers, with the largest DDI categories being related to antihypertensive medications, which are often prescribed together. They found no significant differences between physicians and nurse practitioners on the rate of DDI pairs.

Indication alerts intercept drug name confusion errors during computerized entry of medication orders.
The authors measured whether indication alerts at the time of computerized physician order entry (CPOE) can intercept drug name confusion errors. They found that indication alerts intercepted 1.4 drug name confusion errors per 1000 alerts and recommended that institutions with CPOE consider using indication prompts to intercept drug name confusion errors.

Comparison of droperidol and haloperidol for use by paramedics: assessment of safety and effectiveness.
The goal of this study was to compare QTc prolongation (a measure of cardiac function), adverse events, and effectiveness of droperidol and haloperidol among a cohort of agitated patients in the prehospital setting. There was no significant difference found in QTc prolongation, adverse events, or need for repeat sedation between haloperidol and droperidol.

Cost-effectiveness of a computerized provider order entry system in improving medication safety ambulatory care.
The study objective was to estimate the cost-effectiveness of computerized provider order entry versus traditional paper-based prescribing in reducing medications errors and adverse drug events in the ambulatory setting of mid-sized medical group. Using a decision-analytic model, the researchers found that the adoption of CPOE in the ambulatory setting provides excellent value for the investment.

Prescriber perceptions of a near real-time fax alert program for potential drug-drug interactions.
The purpose of this study was to determine whether prescribers thought that near real-time fax alerts for potential drug-drug interactions (PDDIs) were a good way to communicate with them. The researchers found that physician perceptions of the value of the fax alerts were dependent on which combination of drugs was involved.

Will meaningful use electronic medical records reduce hospital costs?
The authors examined what impact the 5 core medication meaningful use (MU) criteria have on hospital-acquired adverse drug events (ADEs) and their costs in 2010, as a baseline for the start of MU implementation in 2011. They developed a quality indicator to track in-hospital ADEs and concluded that the adoption of core medication MU elements will cut ADE rates, with cost savings that recoup 22% of information technology costs.
