Outpatient Antibiotic Prescribing for Older Adults in the United States: 2011 to 2014.

ABSTRACT:

Objectives

To characterize antibiotics prescribed to older adults to guide efforts to improve antibiotic use.

Design

Descriptive analysis.

Setting

Ambulatory.

Participants

Adults aged 65 and older in the United States.

Measurements

Information on outpatient antibiotic prescriptions dispensed for older adults from 2011 to 2014 was extracted from the IQVIA Xponent database. A chi-square trend analysis was conducted to assess annual changes in antibiotic prescribing rates. A descriptive analysis of prescribing rates by antibiotic, age group, sex, state, Census region, and provider specialty was conducted.

Results

From 2011 to 2014, outpatient antibiotic prescribing rates remained stable in older U.S. adults (P = .89). In 2014, older adults were dispensed 51.6 million prescriptions (1,115 prescriptions/1,000 persons). Persons aged 75 and older had a higher prescribing rate (1,157 prescriptions/1,000 persons) than those aged 65 to 74 (1,084 prescriptions/1,000 persons). Prescribing rates were highest in the South 1228 prescriptions/1,000 persons) and lowest in the West (854 prescriptions/1,000 persons). The most commonly prescribed class was quinolones, followed by penicillins and macrolides. Azithromycin was the most commonly prescribed drug, followed by amoxicillin and ciprofloxacin. Internists and family physicians prescribed 43% of antibiotic courses.

Conclusion

On average, in 2014, U.S. adults aged 65 and older received enough outpatient antibiotic courses for every older adult to receive at least 1. Quinolones and azithromycin are potential targets for assessing the appropriateness of antibiotic prescribing in this population. Interventions to improve use targeting internists and family physicians in the South Census region might have the potential to have the greatest effect.

Project description:ObjectiveTo identify temporal trends in outpatient antibiotic use and antibiotic prescribing practice among older adults in a high income country.DesignObservational study using United States Medicare administrative claims in 2011-15.SettingMedicare, a US national healthcare program for which 98% of older adults are eligible.Participants4.5 million fee-for-service Medicare beneficiaries aged 65 years old and older.Main outcome measurementsOverall rates of antibiotic prescription claims, rates of potentially appropriate and inappropriate prescribing, rates for each of the most frequently prescribed antibiotics, and rates of antibiotic claims associated with specific diagnoses. Trends in antibiotic use were estimated by multivariable regression adjusting for beneficiaries' demographic and clinical covariates.ResultsThe number of antibiotic claims fell from 1364.7 to 1309.3 claims per 1000 beneficiaries per year in 2011-14 (adjusted reduction of 2.1% (95% confidence interval 2.0% to 2.2%)), but then rose to 1364.3 claims per 1000 beneficiaries per year in 2015 (adjusted reduction of 0.20% over 2011-15 (0.09% to 0.30%)). Potentially inappropriate antibiotic claims fell from 552.7 to 522.1 per 1000 beneficiaries over 2011-14, an adjusted reduction of 3.9% (3.7% to 4.1%). Individual antibiotics had heterogeneous changes in use. For example, azithromycin claims per beneficiary decreased by 18.5% (18.2% to 18.8%) while levofloxacin claims increased by 27.7% (27.2% to 28.3%). Azithromycin use associated with each of the potentially appropriate and inappropriate respiratory diagnoses decreased, while levofloxacin use associated with each of those diagnoses increased.ConclusionAmong US Medicare beneficiaries, overall antibiotic use and potentially inappropriate use in 2011-15 remained steady or fell modestly, but individual drugs had divergent changes in use. Trends in drug use across indications were stronger than trends in use for individual indications, suggesting that guidelines and concerns about antibiotic resistance were not major drivers of change in antibiotic use.

Project description:Importance:Benzodiazepines are implicated in a growing number of overdose-related deaths. Objectives:To quantify patterns in outpatient benzodiazepine prescribing and to compare them across specialties and indications. Design, Setting, and Participants:This serial cross-sectional study (January 1, 2003, through December 31, 2015) used nationally representative National Ambulatory Medical Care Survey data. The yearly population-based sample of outpatient visits among adults, ranging from 20?884 visits in 2003 (representing 737 million visits) to 24?273 visits in 2015 (representing 841 million visits) was analyzed. Prescribing patterns were examined by specialty and indication and used to calculate the annual coprescribing rate of benzodiazepines with other sedating medications. Data were analyzed from July 1, 2017, through November 30, 2018. Main Outcomes and Measures:Annual benzodiazepine visit rate. Results:Among the 386 457 ambulatory care visits from 2003 through 2015, a total of 919 benzodiazepine visits occurred in 2003 and 1672 in 2015, nationally representing 27.6 million and 62.6 million visits, respectively. The benzodiazepine visit rate doubled from 3.8% (95% CI, 3.2%-4.4%) to 7.4% (95% CI, 6.4%-8.6%; P?<?.001) of visits. Visits to primary care physicians accounted for approximately half of all benzodiazepine visits (52.3% [95% CI, 50.0%-54.6%]). The benzodiazepine visit rate did not change among visits to psychiatrists (29.6% [95% CI, 23.3%-36.7%] in 2003 to 30.2% [95% CI, 25.6%-35.2%] in 2015; P?=?.90), but increased among all other physicians, including primary care physicians (3.6% [95% CI, 2.9%-4.4%] to 7.5% [95% CI, 6.0%-9.5%]; P?<?.001). The benzodiazepine visit rate increased slightly for anxiety and depression (26.6% [95% CI, 22.6%-31.0%] to 33.5% [95% CI, 28.8%-38.6%]; P?=?.003) and neurologic conditions (6.8% [95% CI, 4.8%-9.5%] to 8.7% [95% CI, 6.2%-12.1%]; P?<?.001), but more so for back and/or chronic pain (3.6% [95% CI, 2.6%-4.9%] to 8.5% [95% CI, 6.0%-11.9%]; P?<?.001) and other conditions (1.8% [95% CI, 1.4%-2.2%] to 4.4% [95% CI, 3.7%-5.2%]; P?<?.001); use did not change for insomnia (26.9% [95% CI, 19.3%-36.0%] to 25.6% [95% CI, 15.3%-39.6%]; P?=?.72). The coprescribing rate of benzodiazepines with opioids quadrupled from 0.5% (95% CI, 0.3%-0.7%) in 2003 to 2.0% (95% CI, 1.4%-2.7%) in 2015 (P?<?.001); the coprescribing rate with other sedating medications doubled from 0.7% (95% CI, 0.5%-0.9%) to 1.5% (95% CI, 1.1%-1.9%) (P?<?.001). Conclusions and Relevance:The outpatient use of benzodiazepines has increased substantially. In light of increasing rates of overdose deaths involving benzodiazepines, understanding and addressing prescribing patterns may help curb the growing use of benzodiazepines.
