Outpatient settings account for the majority of antibiotics used in human health care, and in these settings an estimated 1 in 3 antibiotic prescriptions is unnecessary. Additionally, only half of patients treated with antibiotics for common outpatient conditions receive the recommended first-line drugs. Antibiotic stewardship efforts—which aim to ensure that these drugs are used only when needed and that the most appropriate antibiotic is used at the right dose and duration of treatment—are crucial to improving outpatient prescribing practices, reducing the harm of antibiotic-associated adverse drug events, and minimizing the spread of antibiotic resistance.
To better understand the attitudes of doctors toward antibiotic resistance, inappropriate antibiotic prescribing, and the need for and perceived impact of stewardship interventions, The Pew Charitable Trusts and the American Medical Association conducted a national survey of 1,550 primary care physicians between August and October 2018. Understanding the perceptions that physicians have of these issues can help stakeholders identify and tailor effective strategies to spur the implementation of stewardship efforts.
Key survey findings include:
The survey found a clear need to improve antibiotic prescribing in outpatient health care settings. Even as the number of hospitals with stewardship programs nearly doubled from 2014 to 2017, the adoption of stewardship efforts in outpatient settings continues to lag. Health care stakeholders should leverage these findings to better tailor stewardship interventions and incentivize stewardship efforts in outpatient facilities nationwide.
Outpatient health care settings—such as primary care offices, emergency departments, and urgent care settings—account for the majority of antibiotics prescribed in the United States for human health care.1 However, in some outpatient settings—including primary care offices, emergency departments, and hospital-based clinics—an estimated 1 in 3 antibiotic prescriptions is unnecessary, amounting to some 47 million unnecessary prescriptions each year.2 Additionally, in urgent care clinics, nearly half of visits for diagnoses in which antibiotics are not recommended result in an antibiotic prescription.3 In these health care settings, antibiotic stewardship efforts are essential to reducing inappropriate prescribing, decreasing antibiotic-associated adverse drug events, and minimizing the threat of antibiotic resistance, particularly within the community.
The survey showed a disconnect between respondents’ perceptions of antibiotic resistance and inappropriate outpatient antibiotic prescribing as problems at the national level versus within their own practices. Nearly all physicians surveyed (almost 94%) agreed that antibiotic resistance is a concern in the U.S., but only 55% agreed that it was a problem in their own practices. Additionally, 91% agreed that inappropriate prescribing was an issue nationally, but only 37% agreed that it was a problem within their own practices. The disconnect presents a barrier to stewardship implementation.
Only 26% of the internal medicine and family medicine physicians surveyed ranked antibiotic resistance as a top-three public health issue. Obesity, diabetes, smoking, and opioid misuse outranked resistance as having a greater impact on patients and daily practice. A relatively low ranking may have implications for a physician’s decision to allocate resources for antibiotic stewardship versus other public health initiatives.
In contrast, 73% of pediatricians ranked antibiotic resistance as a top-three issue. Obesity and overweight remained the issue of highest concern among all physicians.
Half of the physicians surveyed disagreed with the statement, “Antibiotic resistance is more of a problem in the hospital and far less important in office-based practices.” This response indicates some recognition that antibiotic resistance is a problem in both inpatient and outpatient settings. Additionally, 65% had seen a rise in resistant infections among their patients over the past five years. This finding is consistent with a 2019 Centers for Disease Control and Prevention (CDC) report, which found an increasing number of community-associated infections caused by resistant pathogens.4
Sixty percent of respondents agreed with the statement, “I prescribe antibiotics more appropriately than the average rate of my peers,” revealing a perception that other clinicians are more responsible for the problem of inappropriate prescribing—and, therefore, the growing threat of antibiotic resistance—than they are. This belief is another potential barrier in the uptake of stewardship activities, as physicians may view improvements in their own prescribing practices as unnecessary.
Forty-seven percent of respondents indicated that they experience moderate pressure from patients or parents to prescribe antibiotics, and an additional 37% experience high or very high pressure. This finding is consistent with previous research showing that patient (or parent) demand is an important driver of outpatient prescribing practices.5
The majority (93%) of physicians surveyed agreed or strongly agreed that inappropriate prescribing in outpatient settings accelerated the emergence of resistant bacteria. To contend with antibiotic resistance, almost 72% agreed or strongly agreed that antibiotic stewardship programs are needed in health care settings, and most respondents (91%) felt that stewardship programs were appropriate for office-based practices.
When asked about implementing stewardship interventions in their own practice, about 47% felt that they would need a lot of help doing so. Respondents were generally open to external organizations providing them with resources and/or technical assistance to support stewardship activities. Local and state departments of health were seen as most helpful (79%), followed by a national public health agency (almost 77%), public payers (about 67%), and commercial payers (64%).
Patient education is a key element of outpatient antibiotic stewardship.6 The majority (almost 79%) of respondents agreed that patient education was essential to ensure the success of stewardship efforts. However, 53% of respondents also felt that a reasonable discussion educating their patients about antibiotic use and resistance was all they needed to do to support stewardship efforts. This finding highlights a potential barrier to the adoption of more comprehensive stewardship efforts, as physicians might be less willing to commit to efforts beyond patient education that may require more time and resources.
Tracking and reporting antibiotic use, particularly at the individual physician level, is another key element of outpatient antibiotic stewardship.7 However, in contrast to patient education, respondents were less supportive of tracking and reporting antibiotic use as a stewardship approach. Half of participants said that tracking appropriate antibiotic use would be difficult to accomplish in a fair and accurate way, and 52% of respondents felt that practice-based antibiotic use reporting requirements would be too onerous. Additionally, about 44% of physicians surveyed felt that health plans (which have access to prescribing data) were in a good position to provide prescribing feedback.
When evaluating which health care organizations were most trusted to provide prescribing feedback, internal medicine and family medicine physicians favored their own practice or health system (about 75% ranked that choice as first or second) and the state department of health (68%). Commercial payers were ranked first or second by almost 30% of these physicians, followed by Medicare (22%) and Medicaid (about 4%). The same pattern emerged among pediatricians, with 88% ranking their own practice or health system first or second, followed by the state department of health (almost 75%), commercial payers (27%), and Medicaid (10%).
Expanding the implementation of outpatient stewardship requires the support of different health care stakeholders. Respondents viewed a wide range of activities from state departments of health, health plans, and payers as likely to spur the implementation of antibiotic stewardship at the practice level. More than 80% of physicians indicated that they would support stewardship in response to the state department of health publishing reports on local antibiotic resistance patterns. Integrating antibiotic stewardship into quality incentive programs—both as a stand-alone program and as part of broader quality efforts—were also promising interventions.
These types of activities can help overcome some of the current barriers to outpatient antibiotic stewardship. For example, providing physicians with local resistance data could help emphasize the importance of this issue in individual communities. Additionally, providing physicians with incentives to implement antibiotic stewardship in their practices could help alleviate resource constraints within practices.
An examination of survey results by medical specialty revealed clear differences between pediatricians and family medicine and internal medicine physicians. Although pediatricians were less likely to view themselves as contributing to inappropriate antibiotic prescribing, they were largely supportive of stewardship implementation and activities. These results may seem to be contradictory, but they do appear to be supported by data showing that pediatricians have largely driven the recent decrease in outpatient antibiotic prescribing.8 Pediatricians’ acceptance of stewardship principles, as well as their perception of less patient or parent pressure to prescribe antibiotics, may already have contributed to this declining antibiotic prescribing trend.
In November 2019, the CDC released a report on the current state of antibiotic resistance threats in the U.S. This analysis showed an increase in community-associated infections caused by resistant pathogens and highlighted the increased need for community-based efforts to combat antibiotic resistance.9 However, findings from this survey demonstrate that work remains to be done to ensure widespread adoption of outpatient antibiotic stewardship activities.
Survey results revealed that physicians have a lack of recognition of their own contribution to inappropriate antibiotic prescribing, concerns over the feasibility of implementing stewardship activities in their own practice, and skepticism of tracking and reporting antibiotic use. These issues all present barriers to implementing stewardship and must be addressed when developing effective stewardship interventions.
On an encouraging note, the respondents indicated that a wide range of activities on the part of health care stakeholders would help motivate stewardship implementation in their practices. Concerted action from all health care stakeholders—from physicians to payers to public health authorities—is needed to ensure stewardship implementation in outpatient facilities nationwide.
Study participants were recruited by M3 from an opt-in, nonprobability panel of health care professionals it maintains who are recruited to participate through various mechanisms—such as direct mail, online recruitment, and professional conferences. Respondents needed to meet the following criteria for eligibility: self-report of board certification in pediatrics, family medicine (FM), or internal medicine (IM); being a full-time physician (excluding residents and fellows) practicing in a primary care outpatient office setting; and spending ≥50% of medical practice time in direct patient care. The data was collected, using a 20-minute online questionnaire, between August and October 2018.
The total of 1,550 participants were stratified based on geographic region (defined as the U.S. Census regions: Northeast, Midwest, South, West) and specialty. Specifically, our recruitment targets were 129 participants per stratum (i.e., family medicine physicians in the Northeast, internal medicine physicians in the Northeast, etc.). Our targets were 130 participants for pediatricians in the Northeast and family medicine physicians in the South to meet our overall target of 1,550 participants. The data was then weighted by geographic region and medical specialty to mirror actual distribution of U.S. physicians according to these characteristics. The American Medical Association’s Physician Masterfile was used to identify true population estimates. Descriptive statistics were generated using Stata v14.2. We used the χ2 test to assess for differences in responses according to medical specialty. As this is a nonprobability survey, it is inappropriate to calculate a margin of sampling error.
