Vaccine communication training using the Brief Motivational Interviewing for Maternal Immunization intervention: A PRISM implementation evaluation

Improving clinician-patient communication can increase uptake of recommended vaccinations during pregnancy. To evaluate adaptations to and pragmatism of the brief Motivational Interviewing for Maternal Immunizations (MI4MI) intervention and to use the Practical Robust Implementation and Sustainability Model (PRISM) to describe context and implementation outcomes among clinician and staff participants. We incorporated data from study team members, clinicians and staff participants, pregnant patients at participating clinics, and patient medical records. Quantitative and qualitative data were collected using surveys, chart reviews, study team notes, interviews, and focus groups. Adaptations were evaluated using the Framework for Reporting Adaptations and Modifications-Enhanced (FRAME) and pragmatism was measured with PRagmatic Explanatory Continuum Indicator Summary (PRECIS-2). MI4MI was effective at improving participants' vaccine communication experiences. Adoption was limited by our recruitment approach. MI4MI implementation was shaped by contextual factors and associated adaptations related to the COVID pandemic and clinic and participant characteristics. Virtual asynchronous intervention delivery had mixed effects on adoption and implementation that varied across clinics and participants. Participants expressed interest in maintaining the MI4MI intervention moving forward; however, identification of sustainability infrastructure was limited. MI4MI was evaluated to be relatively pragmatic. Contextual factors strongly shaped implementation of MI4MI. Future iterations of MI4MI should include training delivery modes and incentives that accommodate a range of participants across job roles and organizational settings. Future studies including control clinics are needed to measure effectiveness for increasing vaccination and comparing virtual versus hybrid implementation strategies.

Recommendations for Prevention and Control of Influenza in Children, 2023-2024

This statement updates the recommendations of the American Academy of Pediatrics for the routine use of influenza vaccine and antiviral medications in the prevention and treatment of influenza in children during the 2023-2024 influenza season. A detailed review of the evidence supporting these recommendations is published in the accompanying technical report (www.pediatrics.org/cgi/doi/10.1542/peds.2023-063773). The American Academy of Pediatrics recommends annual influenza vaccination of all children without medical contraindications starting at 6 months of age. Children are at risk for hospitalization and death from influenza. Influenza vaccination is an important strategy for protecting children and the broader community, as well as reducing the overall burden of respiratory illnesses when other viruses are cocirculating. Any licensed influenza vaccine appropriate for age and health status can be administered, ideally as soon as possible in the season, without preference for one product or formulation over another. Antiviral treatment of influenza is recommended for children with suspected (eg, influenza-like illness [fever with either cough or sore throat]) or confirmed influenza who are hospitalized, have severe or progressive disease, or have underlying conditions that increase their risk of complications of influenza, regardless of duration of illness. Antiviral treatment should be initiated as soon as possible. Antiviral treatment may be considered in the outpatient setting for symptomatic children with suspected or confirmed influenza disease who are not at high risk for influenza complications, if treatment can be initiated within 48 hours of illness onset. Antiviral treatment may also be considered for children with suspected or confirmed influenza disease whose siblings or household contacts either are younger than 6 months or have a high-risk condition that predisposes them to complications of influenza. Antiviral chemoprophylaxis is recommended for the prevention of influenza virus infection as an adjunct to vaccination in certain individuals, especially exposed children who are at high risk for influenza complications but have not yet been immunized or those who are not expected to mount an effective immune response.

The Impact of Altitude at Birth on Perinatal Respiratory Support for Neonates with Trisomy 21

OBJECTIVE

Both high altitude and trisomy 21 (T21) status can negatively impact respiratory outcomes. The objective of this study was to examine the association between altitude and perinatal respiratory support in neonates with T21 compared with those without T21.

STUDY DESIGN

This retrospective cohort study used the United States all-county natality files that included live, singleton, in-hospital births from 2015 to 2019. Descriptive statistics for neonates with and without the primary outcome of sustained assisted ventilation (>6 hours) were compared using t-tests and Chi-squared analyses. Multivariable logistic regression was used to determine the association between respiratory support and the presence of T21, and included an interaction term to determine whether the association between respiratory support and the presence of T21 was modified by elevation at delivery.

RESULTS

A total of 17,939,006 neonates, 4,059 (0.02%) with T21 and 17,934,947 (99.98%) without, were included in the study. The odds of requiring sustained respiratory support following delivery were 5.95 (95% confidence interval [CI]: 5.31, 6.66), 4.06 (95% CI: 2.39, 6.89), 2.36 (95% CI: 1.64, 3.40), and 5.04 (95% CI: 1.54, 16.54) times as high for neonates with T21 than without T21 when born at low, medium, high, and very high elevations, respectively. The odds of requiring immediate ventilation support following delivery were 5.01 (95% CI: 4.59, 5.46), 5.90 (95% CI: 4.16, 8.36), 2.86 (95% CI: 2.15, 3.80), and 12.08 (95% CI: 6.78, 21.51) times as high for neonates with T21 than without T21 when born at low, medium, high, and very high elevation, respectively.

CONCLUSION

Neonates with T21 have increased odds of requiring respiratory support following delivery when compared with neonates without T21 at all categories of altitude. However, the odds ratios did not increase monotonically with altitude which indicates additional research is critical in understanding the effects of altitude on neonates with T21.

KEY POINTS

· Neonates with T21 have an increased need for perinatal respiratory support at all altitudes.. · The odds of needing perinatal respiratory support did not increase monotonically with elevation.. · Additional research is critical to understanding the effects of altitude on neonates with T21..

Recommendations for Prevention and Control of Influenza in Children, 2023-2024

This technical report accompanies the recommendations of the American Academy of Pediatrics for the routine use of influenza vaccine and antiviral medications in the prevention and treatment of influenza in children during the 2023-2024 season. The rationale for the American Academy of Pediatrics recommendation for annual influenza vaccination of all children without medical contraindications starting at 6 months of age is provided. Influenza vaccination is an important strategy for protecting children and the broader community against influenza. This technical report summarizes recent influenza seasons, morbidity and mortality in children, vaccine effectiveness, and vaccination coverage, and provides detailed guidance on vaccine storage, administration, and implementation. The report also provides a brief background on inactivated and live-attenuated influenza vaccines, available vaccines this season, vaccination during pregnancy and breastfeeding, diagnostic testing for influenza, and antiviral medications for treatment and chemoprophylaxis. Strategies to promote vaccine uptake are emphasized.

Understanding the Factors Influencing Health Care Provider Recommendations about Adolescent Vaccines: A Proposed Framework

Health care provider recommendations are among the most important factors influencing parents' decisions to vaccinate their adolescents. However, delivery of high-quality health care provider recommendations for vaccination is not universal. There is wide variation in the strength, timeliness and consistency of the delivery of recommendations for all adolescent vaccines. The factors that influence health care providers' recommendations are multi-level and can be conceptualized in much the same way as vaccine acceptance among parents. Health care providers are influenced by their own attitudes and beliefs about a vaccine and also by the patient they are treating and by the community in which they practice as well as state and national level vaccine policy. We propose a multi-level framework for understanding the factors that influence health care providers' recommendations at the individual, interpersonal and community level to both develop and adapt interventions to improve providers' recommendations.

Motivational interviewing for maternal Immunizations: Intervention development

BACKGROUND AND OBJECTIVE

Vaccine uptake during pregnancy remains low. Our objectives were to describe 1) development and adaptation of a clinician communication training intervention for maternal immunizations and 2) obstetrics and gynecology (ob-gyn) clinician and staff perspectives on the intervention and fit for the prenatal care context.

METHODS

Design of the Motivational Interviewing for Maternal Immunizations (MI4MI) intervention was based on similar communication training interventions for pediatric settings and included presumptive initiation of vaccine recommendations ("You're due for two vaccines today") combined with motivational interviewing (MI) for hesitant patients. Interviews and focus group discussions were conducted with ob-gyn clinicians and staff in five Colorado clinics including settings with obstetric physicians, certified nurse midwives (CNMs), and clinician-trainees. Participants were asked about adapting training to the ob-gyn setting and their implementation experiences. Feedback was incorporated through iterative changes to training components.

RESULTS

Interview and focus group discussion results from participants before (n = 3), during (n = 11) and after (n = 25) implementation guided intervention development and adaptation. Three virtual, asynchronous training components were created: a video and two interactive modules. This virtual format was favored due to challenges attending group meetings; however, participants noted opportunities to practice skills through role-play were lacking. Training modules were adapted to include common challenging vaccine conversations and live-action videos. Participants liked interactive training components and use of adult learning strategies. Some participants initially resisted the presumptive approach but later found it useful after applying it in their practices. Overall, participants reported that MI4MI training fit well with the prenatal context and recommended more inclusion of non-clinician staff.

CONCLUSIONS

MI4MI training was viewed as relevant and useful for ob-gyn clinicians and staff. Suggestions included making training more interactive, and including more complex scenarios and non-clinician staff.

Rural parents' attitudes and beliefs on the COVID-19 pediatric vaccine: An explanatory study

The coronavirus disease 2019 (COVID-19) first came to the Unites States in January 2020. Though adult and pediatric vaccines became available to the public, vaccine uptake among youth and particularly younger children has been gradual. This explanatory study aimed to better understand parents' attitudes and beliefs of the pediatric COVID-19 vaccine and the barriers and facilitators to vaccine uptake in a rural community through a brief, online demographic survey, and in-depth qualitative interviews. Forty-one in depth interviews were conducted with parents (31-English and 10-Spanish-speaking) residing in rural and frontier counties in Colorado between September 2021 and February 2022. Six emergent themes related to COVID-19 pediatric vaccine uptake were identified among the population. These themes spanned the three levels of influence in the Social Ecological Model (individual, interpersonal, and community levels). The six themes were identified as such; 1) Vaccine accessibility was associated with pediatric COVID vaccine uptake in rural communities, 2) Previous pediatric vaccine behaviors were not associated with COVID-19 pediatric vaccine uptake, 3) Perceived health status of a child or family member influenced pediatric COVID-19 vaccine uptake, 4) COVID-19 health seeking behaviors, like COVID pediatric vaccine uptake, are influenced by an individual's prosocial or individualistic perspectives, 5) Child autonomy and "age of consent" frames vaccine decision making behaviors in parents, and lastly 6) Social networks impacted COVID-19 pediatric vaccine decision making. These findings inform next steps for COVID-19 pediatric vaccine uptake including targeted and tailored messaging for communities (cues to actions), engaging youth stakeholders, and identifying trusted sources to build rapport and trust between health professionals and community members. The growing vaccine hesitancy among parents has serious implications for disease eradication and future viral outbreaks. Understanding the perceived barriers and facilitators to pediatric vaccine uptake is important to maintain the health of our youth and communities.

Update From the September 2022 Meeting of the Advisory Committee on Immunization Practices

The Advisory Committee on Immunization Practices (ACIP), a group of medical and public health experts that provides expert advice to the Centers for Disease Control and Prevention, normally meets three times per year to develop US vaccine recommendations. The ACIP increased its meeting frequency over the past 2.5 years to address vaccine-related issues during the severe acute respiratory syndrome coronavirus 2 pandemic. They met to discuss updating coronavirus disease-2019 (COVID-19) booster dose recommendations on September 1, 2022 recommending the use of new bivalent COVID-19 booster vaccines which include equal amounts of ancestral and Omicron BA.4/BA.5 variant mRNA that encodes the spike protein.

Risks of Infectious Diseases in Newborns Exposed to Alternative Perinatal Practices

The purpose of this report is to educate providers about the risk of infectious diseases associated with emerging alternative peripartum and neonatal practices. This report will provide information pediatricians may use to counsel families before birth and to appropriately evaluate and treat neonates who have been exposed to these practices.

Number of Childhood and Adolescent Vaccinations Administered Before and After the COVID-19 Outbreak in Colorado

This study assesses the association of social distancing due to coronavirus disease 2019 (COVID-19) with immunizations administered by age category (0-2 years, 3-9 years, and 10-17 years) in Colorado.

Update From the Advisory Committee on Immunization Practices

The Advisory Committee on Immunization Practices (ACIP), a group of medical and public health experts, normally meets 3 times per year to develop recommendations for vaccine use in the United States. Because of the severe acute respiratory syndrome Coronavirus 2 (SARS-CoV-2) pandemic, there are several SARS-CoV-2 vaccines currently in late-stage clinical trials, so the ACIP is now meeting monthly for single day meetings, with plans to continue standard 2- to 3-day meetings as per usual (February, June, and October). Emergency meetings of ACIP may occur if a vaccine candidate receives an Emergency Use Authorization from the food and drug administration (FDA). This Update provides a combined summary of the August 26 and September 22, 2020, meetings, both of which focused completely on Coronavirus disease 2019 (COVID-19) vaccines. The representatives from the American Academy of Pediatrics (Y. A. M. and D. W. K.) and the Pediatric Infectious Diseases Society (S. T. O.) are present as liaisons to the ACIP.

Cost and reimbursement of providing routine vaccines in outpatient obstetrician/gynecologist settings

OBJECTIVE

To determine the costs and reimbursement associated with running a vaccine program in 5 obstetrics/gynecology practices in Colorado that had participated in a 3-year randomized, controlled trial focused on increasing vaccination in this setting.

MATERIALS AND METHODS

This was a secondary analysis on costs from 5 clinics participating in a cluster-randomized controlled trial that assessed the effectiveness of a multimodal intervention to improve vaccination rates in outpatient obstetrics/gynecology clinics in central Colorado. The intervention included designation of an immunization champion within the practice, purchasing recommended vaccines for the practice, guidance on storage and management, implementing practices for routine identification of eligible patients for vaccination using the medical record, implementation of standing orders for vaccination, and vaccine administration to patients. Data on costs were gathered from office invoices, claims data, surveys and in-person observations during the course of the trial. These data incorporated supply and personnel costs for administering vaccines to individual patients that were derived from a combination of time-motion studies of staff and provider clinical activity, and practice reports, as well as costs related to maintaining the vaccination program at the practice level, which were derived from practice reports and invoices. Cost data for personnel time during visits in which vaccination was assessed and/or discussed, but no vaccine was given to the patient were also included in the main analysis. Data on practice revenue were derived from practice reimbursement records. All costs were described in 2014 dollars. The primary analysis was the proportion of costs for the program that were reimbursed, aggregated over all years of the study and combining all vaccines and practices, separated by obstetrics vs gynecology patients.

RESULTS

Collectively the 5 clinics served >40,000 patient during the study period and served a population that was 16% Medicaid. Over the 3-year observation period, there were 6573 vaccination claims made collectively by the practices (4657 for obstetric patients, 1916 for gynecology patients). The most expensive component of the program was the material costs of the vaccines themselves, which ranged from a low of $9.67 for influenza vaccines, to a high of $141.40 for human papillomavirus vaccine. Staff costs for assessing and delivering vaccines during patient visits were minimal ($0.09-$1.24 per patient visit depending on the practice and whether an obstetrics or gynecology visit was being assessed) compared with staff costs for maintaining the program at a practice level (ie, assessing inventory, ordering and stocking vaccines; $0.89-$105.89 per vaccine dose given). When assessing all costs compared with all reimbursement, we found that vaccines for obstetrics patients were reimbursed at 159% of the costs over the study period, and for gynecology patients at 97% of the costs. Overall, the vaccination program was financially favorable across the practices, averaging 125% reimbursement of costs across the three study years.

CONCLUSION

Providing routine vaccines to patients in the ambulatory obstetrics/gynecology setting is generally not financially prohibitive for practices, and may even be financially beneficial, though there is variability between practices that can affect the overall reimbursement margin.

Policies Among US Pediatricians for Dismissing Patients for Delaying or Refusing Vaccination

This survey study assesses US pediatrician practices and office policies in response to parents who either refuse primary vaccinations or request to spread out individual vaccines in the primary series.

Latent Class Analysis of Maternal Vaccine Attitudes and Beliefs

Background. Maternal vaccine coverage is suboptimal, and a substantial proportion of parents have concerns about vaccines. Most parents seek out vaccine information during and immediately after their first pregnancy. No study to our knowledge has analyzed survey data to identify homogeneous groups of pregnant women based on their vaccine attitudes and beliefs. Aims. To identify homogeneity among groups of pregnant women based on their vaccine attitudes and beliefs to facilitate audience segmentation and targeting of tailored educational interventions. Method. Between June 2017 and July 2018, we surveyed 2,196 pregnant women recruited from geographically and sociodemographically diverse prenatal care practices in Georgia and Colorado. We then performed a latent class analysis to identify homogeneity among groups of pregnant women. Results. Our latent class analysis produced three groups of pregnant women: vaccine supporters (36% of women), vaccine acceptors (41%), and vaccine skeptics (23%). Discussion. The major difference between the supporters and the acceptors were whether they mostly “strongly agreed” or just “agreed” to Likert-type scale survey items assessing their vaccine attitudes and beliefs. The skeptics most frequently chose “disagree” or “don’t know” for items assessing attitudinal constructs such as confidence in vaccine safety and efficacy and disease susceptibility. However, even skeptics often chose “agree” for items assessing constructs such as disease severity and self-efficacy. Conclusions. This article provides useful insight into the homogeneity among groups of pregnant women based on their vaccine attitudes and beliefs. This knowledge should help facilitate audience segmentation and targeting of tailored educational interventions among this population.

Use of Standing Orders for Vaccination Among Pediatricians

OBJECTIVES

Standing orders are an effective way to increase vaccination rates, yet little is known about how pediatricians use this strategy for childhood immunizations. We assessed current use of, barriers to using, and factors associated with use of standing orders for vaccination among pediatricians.

METHODS

Internet and mail survey from June 2017 to September 2017 among a nationally representative sample of pediatricians. In the principal component analysis of barrier items, we identified 2 factors: physician responsibility and concerns about office processes. A multivariable analysis that included barrier scales and physician and/or practice characteristics was used to identify factors associated with use of standing orders.

RESULTS

The response rate was 79% (372 of 471); 59% of respondents reported using standing orders. The most commonly identified barriers among nonusers were concern that patients may mistakenly receive the wrong vaccine (68%), concern that patients prefer to speak with the physician about a vaccine before receiving it (62%), and belief that it is important for the physician to be the person who recommends a vaccine to patients (57%). These 3 items also made up the physician responsibility barrier factor. Respondents with higher physician responsibility scores were less likely to use standing orders (risk ratio: 0.59 [95% confidence interval: 0.53-0.66] per point increase). System-level decision-making about vaccines, suburban or rural location, and lower concerns about office processes scores were each associated with use of standing orders in the bivariate, but not the multivariable, analysis.

CONCLUSIONS

Among pediatricians, use of standing orders for vaccination is far from universal. Interventions to increase use of standing orders should address physicians' attitudinal barriers as well as organizational factors.

Primary care physician knowledge, attitudes, and diagnostic testing practices for norovirus and acute gastroenteritis

BACKGROUND

Norovirus is a leading cause of acute gastroenteritis (AGE) across the age spectrum; candidate vaccines are in clinical trials. While norovirus diagnostic testing is increasingly available, stool testing may not be performed routinely, which can hamper surveillance and burden of disease estimates. Additionally, lack of knowledge of the burden of disease may inhibit provider vaccine recommendations, which could affect coverage rates and ultimately the impact of the vaccine. Our objectives were to understand physicians' stool testing practices in outpatients with AGE, and physician knowledge of norovirus, in order to improve surveillance and prepare for vaccine introduction.

METHODS

Internet and mail survey on AGE, norovirus, and future norovirus vaccines conducted January to March 2018 among national networks of primary care pediatricians, family practice and general internal medicine physicians.

RESULTS

The response rate was 59% (820/1383). During peak AGE season, physicians estimated they ordered stool tests for a median of 15% (interquartile range: 5-33%) of their outpatients with AGE. Stool tests were reported as more often available for ova and parasites, Clostridioides difficile, and bacterial culture (>95% for all specialties) than for norovirus (6-33% across specialties); even when available, norovirus-specific tests were infrequently ordered. Most providers were unaware that norovirus is a leading cause of AGE across all age groups (Pediatricians 80%, Family Practice 86%, General Internal Medicine 89%) or that alcohol-based hand sanitizers are ineffective against norovirus (Pediatricians 51%, Family Practice 66%, General Internal Medicine 62%). Concerns cited as major barriers to implementing a future norovirus vaccine included if the vaccine is not covered by insurance (General Internal Medicine 64%, Pediatricians 67%, Family Practice 74%) and lack of adequate reimbursement for vaccination (Pediatricians 43%, General Internal Medicine 46%, Family Practice 50%). Factors that providers believed were 'not at all a barrier' or 'minor barrier' to new vaccine introduction included the belief that "my patients won't need this vaccine" (General Internal Medicine 78%, Family Practice 86%, Pediatricians 90%) and "my patients already get too many vaccines" (Family Practice 89%, General Internal Medicine 92%, Pediatricians 95%).

CONCLUSIONS

Primary care physicians had few concerns regarding future norovirus vaccine introduction, but have knowledge gaps on norovirus prevalence and hand hygiene for prevention. Also, physicians infrequently order stool tests for outpatients with AGE, which limits surveillance estimates that rely on physician-ordered stool diagnostics. Closing physician knowledge gaps on norovirus burden and transmission can help support norovirus vaccine introduction.

Building Trust: Clergy and the Call to Eliminate Religious Exemptions

The AAP has prioritized eliminating religious vaccine exemptions. Clergy are key stakeholders with diverse vaccination views. Community-centered approaches are essential to building trust with them.

Management of Infants at Risk for Group B Streptococcal Disease

Group B streptococcal (GBS) infection remains the most common cause of neonatal early-onset sepsis and a significant cause of late-onset sepsis among young infants. Administration of intrapartum antibiotic prophylaxis is the only currently available effective strategy for the prevention of perinatal GBS early-onset disease, and there is no effective approach for the prevention of late-onset disease. The American Academy of Pediatrics joins with the American College of Obstetricians and Gynecologists to reaffirm the use of universal antenatal microbiologic-based testing for the detection of maternal GBS colonization to facilitate appropriate administration of intrapartum antibiotic prophylaxis. The purpose of this clinical report is to provide neonatal clinicians with updated information regarding the epidemiology of GBS disease as well current recommendations for the evaluation of newborn infants at risk for GBS disease and for treatment of those with confirmed GBS infection. This clinical report is endorsed by the American College of Obstetricians and Gynecologists (ACOG), July 2019, and should be construed as ACOG clinical guidance.

Management of Neonates Born at ≤34 6/7 Weeks' Gestation With Suspected or Proven Early-Onset Bacterial Sepsis

Early-onset sepsis (EOS) remains a serious and often fatal illness among infants born preterm, particularly among newborn infants of the lowest gestational age. Currently, most preterm infants with very low birth weight are treated empirically with antibiotics for risk of EOS, often for prolonged periods, in the absence of a culture-confirmed infection. Retrospective studies have revealed that antibiotic exposures after birth are associated with multiple subsequent poor outcomes among preterm infants, making the risk/benefit balance of these antibiotic treatments uncertain. Gestational age is the strongest single predictor of EOS, and the majority of preterm births occur in the setting of other factors associated with risk of EOS, making it difficult to apply risk stratification strategies to preterm infants. Laboratory tests alone have a poor predictive value in preterm EOS. Delivery characteristics of extremely preterm infants present an opportunity to identify those with a lower risk of EOS and may inform decisions to initiate or extend antibiotic therapies. Our purpose for this clinical report is to provide a summary of the current epidemiology of preterm neonatal sepsis and provide guidance for the development of evidence-based approaches to sepsis risk assessment among preterm newborn infants.

Management of Neonates Born at ≥35 0/7 Weeks' Gestation With Suspected or Proven Early-Onset Bacterial Sepsis

The incidence of neonatal early-onset sepsis (EOS) has declined substantially over the last 2 decades, primarily because of the implementation of evidence-based intrapartum antimicrobial therapy. However, EOS remains a serious and potentially fatal illness. Laboratory tests alone are neither sensitive nor specific enough to guide EOS management decisions. Maternal and infant clinical characteristics can help identify newborn infants who are at risk and guide the administration of empirical antibiotic therapy. The incidence of EOS, the prevalence and implications of established risk factors, the predictive value of commonly used laboratory tests, and the uncertainties in the risk/benefit balance of antibiotic exposures all vary significantly with gestational age at birth. Our purpose in this clinical report is to provide a summary of the current epidemiology of neonatal sepsis among infants born at ≥35 0/7 weeks' gestation and a framework for the development of evidence-based approaches to sepsis risk assessment among these infants.

Adoption of Serogroup B Meningococcal Vaccine Recommendations

: media-1vid110.1542/5799875076001PEDS-VA_2018-0344Video Abstract BACKGROUND AND OBJECTIVES: In 2015, the Advisory Committee on Immunization Practices recommended that 16- to 23-year-olds may be vaccinated with the serogroup B meningococcal (MenB) vaccine on the basis of individual clinical decision-making (Category B). We assessed the following among US pediatricians and family physicians (FPs): (1) practices regarding MenB vaccine delivery, (2) factors influencing a decision to recommend the MenB vaccine, and (3) factors associated with discussing the MenB vaccine.

METHODS

We surveyed a nationally representative sample of pediatricians and FPs via e-mail and Internet from October 2016 to December 2016.

RESULTS

The response rate was 72% (660 of 916). During routine visits, 51% of pediatricians and 31% of FPs reported always or often discussing MenB vaccine. Among those who discussed often or always, 91% recommended vaccination; among those who never or rarely discussed, 11% recommended. We found that 73% of pediatricians and 41% of FPs currently administered the MenB vaccine. Although many providers reported not knowing about factors influencing recommendation decisions, MenB disease outbreaks (89%), disease incidence (62%), and effectiveness (52%), safety (48%), and duration of protection of MenB vaccine (39%) increased the likelihood of recommendation, whereas the Category B recommendation (45%) decreased likelihood. Those somewhat or not at all aware of the MenB vaccine (risk ratio 0.32 [95% confidence interval 0.25-0.41]) and those practicing in a health maintenance organization (0.39 [0.18-0.87]) were less likely, whereas those aware of disease outbreaks in their state (1.25 [1.08-1.45]) were more likely to discuss MenB vaccine.

CONCLUSIONS

Primary care physicians have significant gaps in knowledge about MenB disease and the MenB vaccine, and this appears to be a major driver of the decision not to discuss the vaccines.

Effect of a Health Care Professional Communication Training Intervention on Adolescent Human Papillomavirus Vaccination: A Cluster Randomized Clinical Trial

IMPORTANCE

The incidence of human papillomavirus (HPV)-related cancers is more than 35 000 cases in the United States each year. Effective HPV vaccines have been available in the United States for several years but are underused among adolescents, the target population for vaccination. Interventions to increase uptake are needed.

OBJECTIVE

To evaluate the effect of a 5-component health care professional HPV vaccine communication intervention on adolescent HPV vaccination.

DESIGN, SETTING, AND PARTICIPANTS

A cluster randomized clinical trial using covariate-constrained randomization to assign study arms and an intent-to-treat protocol was conducted in 16 primary care practices in the Denver, Colorado, metropolitan area. Participants included 188 medical professionals and 43 132 adolescents.

INTERVENTIONS

The 5 components of the intervention were an HPV fact sheet library to create customized information sheets relevant to each practice's patient population, a tailored parent education website, a set of HPV-related disease images, an HPV vaccine decision aid, and 2½ hours of communication training on using a presumptive vaccine recommendation, followed by motivational interviewing if parents were resistant to vaccination. Each practice participated in a series of 2 intervention development meetings over a 6-month period (August 1, 2014, to January 31, 2015) before the intervention.

MAIN OUTCOMES AND MEASURES

Differences between control and intervention changes over time (ie, difference in differences between the baseline and intervention period cohorts of patients) in HPV vaccine series initiation (≥1 dose) and completion (≥3 doses) among patients aged 11 to 17 years seen at the practices between February 1, 2015, and January 31, 2016. Vaccination data were obtained from the practices' records and augmented with state immunization information system data.

RESULTS

Sixteen practices and 43 132 patients (50.3% female; median age, 12.6 years [interquartile range, 10.8-14.7 years] at the beginning of the study period) participated in this trial. Adolescents in the intervention practices had significantly higher odds of HPV vaccine series initiation (adjusted odds ratio [aOR], 1.46; 95% CI, 1.31-1.62) and completion (aOR, 1.56; 95% CI, 1.27-1.92) than those in the control practices (a 9.5-absolute percentage point increase in HPV vaccine series initiation and a 4.4-absolute percentage point increase in HPV vaccine series completion in intervention practices). The intervention had a greater effect in pediatric practices compared with family medicine practices and in private practices compared with public ones. Health care professionals reported that communication training and the fact sheets were the most used and useful intervention components.

CONCLUSIONS AND RELEVANCE

A health care professional communication intervention significantly improved HPV vaccine series initiation and completion among adolescent patients.

Characteristics of mobile phone access and usage in rural and urban Guatemala: assessing feasibility of text message reminders to increase childhood immunizations

BACKGROUND

Despite efforts to promote vaccination in low- and middle-income countries (LMICs), over 20 million infants remain under-immunized and at risk for unnecessary morbidity and mortality. Mobile health technologies, such as Short Message Service (SMS) texts, have tremendous and untapped potential for disease management. Patient reminder systems are an important mechanism for improving childhood vaccination coverage and can be easily adapted to SMS platforms. However, current research lacks an understanding of the barriers and facilitators to mHealth program design, implementation, and scale in LMICs.

METHODS

We analyzed survey data collected March-November 2016 at the enrollment visit from a randomized controlled trial conducted at public health clinics in urban and rural Guatemala. Participants included eligible infants 6 weeks to 6 months of age receiving the first dose of the primary immunization series. At least one parent needed to own a mobile phone and be capable of deciphering SMS. Chi-square or Fisher's exact and Student's t-test were used to assess significance levels in demographic differences to describe factors that contribute to the feasibility of using an SMS-based vaccination reminder system.

RESULTS

Of 1,088 families approached for enrollment, 871 were eligible and 720 (82.7%) participated with equal numbers of urban and rural children enrolled; 54 parents did not own a mobile phone with SMS capability and three parents could not use SMS. There was no significant difference between urban and rural maternal mobile phone ownership (94.4% vs. 93.3%, P=0.53), but more urban fathers owned mobile phones (72.8% vs. 47.1%, P<0.0001) and, overall, more mothers compared to fathers owned mobile phones (93.9% vs. 61.1%, P<0.0001). Most families (90.4%) chose to have reminders sent to the mother. Urban participants reported more mobile phones present in the home (P<0.0001), but rural participants reported more telephone landlines (34.7% vs. 15.6%, P<0.0001). Most participants reported a daily average of ≤5 telephone calls made (87.4%), ≤10 texts sent (91.0%), and ≤10 texts received (89.9%), with urban families reporting greater telephone usage (P=0.006, P<0.001, and P<0.001 respectively). Parents preferred to make calls over sending texts (74.7% vs. 25.3%, P<0.0001), with more urban families preferring text messaging (31.9% vs. 18.6%, P<0.0001).

CONCLUSIONS

Our study results provide important insight into mobile phone access, usage, and preferences for voice and text communication across rural and urban populations of an LMIC that can be used to inform future mHealth interventions. Our findings suggest that offering a combination of more traditional communication methods with newer, modern technologies may be more effective at reminding families about vaccination visits, particularly for our rural population, and that targeting mothers for mobile phone interventions may provide the greatest benefits. Overall, our study suggests that using SMS reminders in LMICs can be a feasible tool for public health interventions.

Knowledge and Attitudes Regarding Category B ACIP Recommendations Among Primary Care Providers for Children

OBJECTIVE

In 2015, the Advisory Committee on Immunization Practices (ACIP) made a category B recommendation for use of serogroup B meningococcal (MenB) vaccines, meaning individual clinical decision-making should guide recommendations. This was the first use of a category B recommendation pertaining to a large population and the first such recommendation for adolescents. As part of a survey regarding MenB vaccine, our objectives were to assess among pediatricians (Peds) and family physicians (FPs) nationally: 1) knowledge of the meaning of category A versus B recommendations and insurance coverage implications, and 2) attitudes about category A and B recommendations.

METHODS

We surveyed a nationally representative sample of Peds and FPs via e-mail and mail from October to December 2016.

RESULTS

The response rate was 72% (660 of 916). Although >80% correctly identified the definition of a category A recommendation, only 24% were correct about the definition for category B. Fifty-five percent did not know that private insurance would pay for vaccines recommended as category B, and 51% did not know that category B-recommended vaccines would be covered by the Vaccines for Children program. Fifty-nine percent found it difficult to explain category B recommendations to patients; 22% thought ACIP should not make category B recommendations; and 39% were in favor of category B recommendations because they provide leeway in decision-making.

CONCLUSIONS

For category B recommendations to be useful in guiding practice, primary care clinicians will need to have a better understanding of their meaning, their implications for insurance payment, and guidance on how to discuss them with parents and patients.

Web-based Social Media Intervention to Increase Vaccine Acceptance: A Randomized Controlled Trial

BACKGROUND

Interventions to address vaccine hesitancy and increase vaccine acceptance are needed. This study sought to determine if a Web-based, social media intervention increases early childhood immunization.

METHODS

A 3-arm, randomized controlled trial was conducted in Colorado from September 2013 to July 2016. Participants were pregnant women, randomly assigned (3:2:1) to a Web site with vaccine information and interactive social media components (VSM), a Web site with vaccine information (VI), or usual care (UC). Vaccination was assessed in infants of participants from birth to age 200 days. The primary outcome was days undervaccinated, measured as a continuous and dichotomous variable.

RESULTS

Infants of 888 participants were managed for 200 days. By using a nonparametric rank-based analysis, mean ranks for days undervaccinated were significantly lower in the VSM arm versus UC (P = .02) but not statistically different between the VI and UC (P = .08) or between VSM and VI arms (P = .63). The proportions of infants up-to-date at age 200 days were 92.5, 91.3, and 86.6 in the VSM, VI, and UC arms, respectively. Infants in the VSM arm were more likely to be up-to-date than infants in the UC arm (odds ratio [OR] = 1.92; 95% confidence interval [CI], 1.07-3.47). Up-to-date status was not statistically different between VI and UC arms (OR = 1.62; 95% CI, 0.87-3.00) or between the VSM and VI arms (OR = 1.19, 95% CI, 0.70-2.03).

CONCLUSIONS

Providing Web-based vaccine information with social media applications during pregnancy can positively influence parental vaccine behaviors.

Recommendations for Prevention and Control of Influenza in Children, 2017 - 2018

This statement updates the recommendations for routine use of the seasonal influenza vaccine and antiviral medications for the prevention and treatment of influenza in children. The American Academy of Pediatrics recommends annual seasonal influenza immunization for everyone 6 months and older, including children and adolescents. Highlights for the upcoming 2017-2018 season include the following:1. Annual universal influenza immunization is indicated with either a trivalent or quadrivalent (no preference) inactivated vaccine;2. The 2017-2018 influenza A (H1N1) vaccine strain differs from that contained in the 2016-2017 seasonal vaccines. The 2017-2018 influenza A (H3N2) vaccine strain and influenza B vaccine strains included in the trivalent and quadrivalent vaccines are the same as those contained in the 2016-2017 seasonal vaccines: a. trivalent vaccine contains an A/Michigan/45/2015 (H1N1)pdm09-like virus, an A/Hong Kong/4801/2014 (H3N2)-like virus, and a B/Brisbane/60/2008-like virus (B/Victoria lineage); and b. quadrivalent vaccine contains an additional B virus (B/Phuket/3073/2013-like virus [B/Yamagata lineage]);3. Quadrivalent live attenuated influenza vaccine (LAIV4) is not recommended for use in any setting in the United States during the 2017-2018 influenza season. This interim recommendation, originally made in 2016, followed observational data from the US Influenza Vaccine Effectiveness Network revealing that LAIV4 performed poorly against influenza A (H1N1)pdm09 viruses in recent influenza seasons;4. All children with an egg allergy of any severity can receive an influenza vaccine without any additional precautions beyond those recommended for any vaccine;5. All health care personnel should receive an annual seasonal influenza vaccine, a crucial step in preventing influenza and reducing health care-associated influenza infections, because health care personnel often care for individuals at high risk for influenza-related complications; and6. Pediatricians should attempt to promptly identify children suspected of having influenza infection for timely initiation of antiviral treatment, when indicated, to reduce morbidity and mortality. Best results are seen when treated within 48 hours of symptom onset.

Noninitiation and Noncompletion of HPV Vaccine Among English- and Spanish-Speaking Parents of Adolescent Girls: A Qualitative Study

OBJECTIVE

The Advisory Committee on Immunization Practices recommends routine human papillomavirus (HPV) vaccination for female adolescents aged 11 to 12 years, yet vaccination rates remain low. We conducted a qualitative study to understand English- and Spanish-speaking parents' reasons for noninitiation or noncompletion of the HPV vaccine series for their daughters.

METHODS

Parents of female adolescents aged 12 to 15 years who had not initiated or not completed the HPV vaccine series were identified through administrative data in 2 large urban safety net health care systems in Colorado. Focus groups and in-depth interviews were conducted with English-speaking parents and in-depth interviews were conducted with Spanish-speaking parents. All data were recorded, transcribed, and analyzed for thematic content by experienced analysts using established qualitative content analysis techniques.

RESULTS

Forty-one parents participated in the study. Thirty parents participated in individual interviews and 11 parents participated in 1 of 2 focus groups. The most common reasons for noninitiation and noncompletion among English-speaking parents included a low perceived risk of HPV infection, vaccine safety concerns, and distrust of government and/or medicine. In contrast, Spanish-speaking parents most often reported that providers had either not encouraged initiation of the HPV vaccine series or had not explained the necessity of completing the series. Some noninitiating parents, particularly Spanish-speaking ones, also cited concerns that vaccination would encourage sexual activity.

CONCLUSIONS

The reasons for noninitiation and noncompletion of the HPV vaccine series differed substantially between English- and Spanish-speaking parents. To maximize uptake of HPV vaccine, varying approaches might be needed to effectively target specific populations.

Effect of a multi-modal intervention on immunization rates in obstetrics and gynecology clinics

BACKGROUND

There is increasing attention on immunizations by obstetrician-gynecologists and a need to improve vaccination rates for all women.

OBJECTIVE

To evaluate the effect of a multimodal intervention on rates of immunization with tetanus, diphtheria, and acellular pertussis (Tdap); human papillomavirus (HPV); and influenza in outpatient obstetrics and gynecology clinics.

STUDY DESIGN

Immunization rates at 2 clinics were compared pre- and post-implementation of multiple interventions at a public integrated health-care system. Study interventions began on June 6, 2012 and concluded on May 31, 2014; the preimplementation time period used was June 6, 2010 to June 5, 2012. Interventions included stocking of immunizations in clinics, revision and expansion of standing orders, creation of a reminder/recall program, identification of an immunization champion to give direct provider feedback, expansion of a payment assistance program, and staff education. All women aged 15 and older who made a clinic visit during influenza season were included in the influenza cohort; women who delivered an infant during the study time period and had at least 1 prenatal visit within 9 months preceding delivery were included in the Tdap cohort; each clinic visit by a nonpregnant woman aged 15-26 years was assessed and included in the HPV analysis as an eligible visit if the patient was lacking any of the 3 HPV vaccines in the series. The primary outcome was receipt of influenza and Tdap vaccine per current American College of Obstetricians and Gynecologists guidelines and receipt of HPV vaccine during eligible visits. Influenza and Tdap were assessed with overall coverage rates at the institutional level, and HPV was assessed at the visit level by captured opportunities. All analyses included generalized estimating equations and the primary outcome was assessed with time as a covariate in all models.

RESULTS

A total of 19,409 observations were included in the influenza cohort (10,231 pre- and 9178 post-intervention), 2741 in the Tdap cohort (1248 pre- and 1493 post-intervention), and 12,443 in the HPV cohort (7966 pre- and 4477 post-intervention). Our population was largely Hispanic, English-speaking, and publicly insured. The rate of influenza vaccination increased from 35.4% pre-intervention to 46.0% post-intervention (P < .001). The overall rate for Tdap vaccination increased from 87.6% pre-intervention to 94.5% post-intervention until the recommendation to vaccinate during each pregnancy was implemented (z = 4.58, P < .0001). The average Tdap up-to-date rate after that recommendation was 75.0% (z = -5.77, P < .0001). The overall rate of HPV vaccination with an eligible visit increased from 7.1% before to 23.7% after the intervention.

CONCLUSION

Using evidence-based practices largely established in other settings, our intervention was associated with increased rates of influenza, Tdap, and HPV vaccination in outpatient underserved obstetrics and gynecology clinics. Integrating such evidence-based practices into routine obstetrics and gynecology care could positively impact preventive health for many women.

Parental Choice of Recall Method for HPV Vaccination: A Pragmatic Trial

OBJECTIVES

Completion rates for the human papillomavirus vaccine (HPV) series among adolescents remain low. Effectiveness of recall with parents choosing the method (preference-based recall) for increasing HPV series completion is unstudied. Within a cluster-randomized trial, we examined effectiveness of preference-based recall compared with usual care for increasing series completion and the association of recall choices with completion.

METHODS

All Kaiser Permanente Colorado pediatric practices (n = 7) were randomized to intervention (n = 4) or control (n = 3) by using covariate-constrained randomization. From January to June 2013, parents at intervention practices whose adolescents received HPV 1 were asked the recall method they preferred for subsequent doses and if they also wanted their child reminded. Completion rates were assessed 1 year after HPV 1.

RESULTS

At intervention practices, 374 (43%) of 867 patients were enrolled; 39% preferred text, 18% e-mail, 9% auto-dialer, and 34% 2-methods; 19% chose to have adolescent also recalled. Intervention adolescents were more likely to complete (63% vs 38%) than were controls (adjusted risk ratio 1.47 [1.38-1.57]) and less likely to be late in completing the series (45% vs 57%, P = .02). Rates of completion were similar between different recall methods, but significantly higher for those preferring e-mail and phone compared withother methods (90% vs 60%. P = .008). Completion rates were similar for adolescents who also received recalls (62%) versus those who did not (63%).

CONCLUSIONS

Preference-based recall was effective in increasing HPV series completion rates, with point estimates substantially higher than for most published studies of reminder/recall.

Provider Attitudes Regarding Vaccine Tracking Systems in Pediatric Practices

OBJECTIVE

To assess among US pediatricians' systems for tracking vaccine administration and inventory and attitudes about these systems; and attitudes regarding and perceived barriers to adoption of a 2-dimensional bar code systems.

METHODS

Internet and mail survey of a nationally representative network of pediatricians between September 2011 and January 2012.

RESULTS

The response rate was 71% (288 of 408). The most common methods for recording vaccine information were manual entry into an electronic (52%) or paper (27%) record; 76% recorded information in ≥2 places. Physicians reported ordering vaccine on the basis of seasonal increases in demand (55%), paper-based inventory (52%), or when stock looks low (47%); 79% reported it was time consuming to track inventory and 24% reported their practices frequently run out of vaccines. Among those participating in an immunization information system, 29% transmitted data by automatic uploads and 58% entered data manually. Physicians agreed that bar codes could facilitate tracking of vaccine inventory (96%), would improve patient safety (96%), would be more reliable and accurate than current systems (93%), and could improve the efficiency of vaccine administration (90%). Barriers to adoption of a bar code system included need for software (52%), information technology support (42%), and computer equipment (33%). The total cost at which >50% reported they would definitely or probably adopt a bar code system was between $1000 and $4999.

CONCLUSIONS

Most pediatricians report using inefficient systems for tracking vaccine administration and inventory and recognize multiple potential benefits of incorporating vaccine bar coding into their practice. To facilitate adoption, costs will need to be contained and technological barriers addressed.

Characteristics of Physicians Who Dismiss Families for Refusing Vaccines

BACKGROUND AND OBJECTIVES

Physicians dismissing families who refuse vaccines from their practices is controversial. We assessed the following among pediatricians (Peds) and family physicians (FPs): (1) reported prevalence of parental refusal of 1 or more vaccines in the infant series; (2) physician response to refusal; and (3) the association between often/always dismissing families and provider/practice characteristics and state exemption laws.

METHODS

Nationally representative survey conducted June to October 2012. A multivariable analysis assessed association of often/always dismissing families with physician/practice characteristics, state philosophical exemption policy, and degree of difficulty obtaining nonmedical exemptions.

RESULTS

The response rate was 66% (534/815). Overall, 83% of physicians reported that in a typical month, ≥1% of parents refused 1 or more infant vaccines, and 20% reported that >5% of parents refused. Fifty-one percent reported always/often requiring parents to sign a form if they refused (Peds 64%, FP 29%, P < .0001); 21% of Peds and 4% of FPs reported always/often dismissing families if they refused ≥1 vaccine. Peds only were further analyzed because few FPs dismissed families. Peds who dismissed families were more likely to be in private practice (adjusted odds ratio [aOR] 4.90, 95% confidence interval [CI] 1.40-17.19), from the South (aOR 4.07, 95% CI 1.08-15.31), and reside in a state without a philosophical exemption law (aOR 3.70, 95% CI 1.74-7.85).

CONCLUSIONS

Almost all physicians encounter parents who refuse infant vaccines. One-fifth of Peds report dismissing families who refuse, but there is substantial variation in this practice. Given the frequency of dismissal, the impact of this practice on vaccine refusers and on pediatric practices should be studied.

Effectiveness and Cost of Bidirectional Text Messaging for Adolescent Vaccines and Well Care

OBJECTIVE

To evaluate the effectiveness and cost of bidirectional short messaging service in increasing rates of vaccination and well child care (WCC) among adolescents.

METHODS

We included all adolescents needing a recommended adolescent vaccine (n = 4587) whose parents had a cell-phone number in 5 private and 2 safety-net pediatric practices. Adolescents were randomized to intervention (n = 2228) or control (n = 2359). Parents in the intervention group received up to 3 personalized short messaging services with response options 1 (clinic will call to schedule), 2 (parent will call clinic), or STOP (no further short messaging service). Primary outcomes included completion of all needed services, WCC only, all needed vaccinations, any vaccination, and missed opportunity for vaccination.

RESULTS

Intervention patients were more likely to complete all needed services (risk ratio [RR] 1.31, 95% confidence interval [CI] 1.12-1.53), all needed vaccinations (RR 1.29, 95% CI 1.12-1.50), and any vaccination (RR 1.36, 95% CI 1.20-1.54). Seventy-five percent of control patients had a missed opportunity versus 69% of intervention (P = .002). There was not a significant difference for WCC visits. Responding that the clinic should call to schedule ("1") was associated with the highest effect size for completion of all needed services (RR 1.89, 95% CI 1.41-2.54). Net cost ranged from $855 to $3394 per practice.

CONCLUSIONS

Bidirectional short messaging service to parents was effective at improving rates for all adolescent vaccinations and for all needed services, especially among parents who responded they desired a call from the practice.

Physician response to parental requests to spread out the recommended vaccine schedule

OBJECTIVES

To assess among US physicians (1) frequency of requests to spread out recommended vaccination schedule for children <2 years, (2) attitudes regarding such requests, and (3) strategies used and perceived effectiveness in response to such requests.

METHODS

An e-mail and mail survey of a nationally representative sample of pediatricians and family physicians from June 2012 through October 2012.

RESULTS

The response rate was 66% (534 of 815). In a typical month, 93% reported some parents of children <2 years requested to spread out vaccines; 21% reported ≥ 10% of parents made this request. Most respondents thought these parents were putting their children at risk for disease (87%) and that it was more painful for children (84%), but if they agreed to requests, it would build trust with families (82%); further, they believed that if they did not agree, families might leave their practice (80%). Forty percent reported this issue had decreased their job satisfaction. Most agreed to spread out vaccines when requested, either often/always (37%) or sometimes (37%); 2% would often/always, 4% would sometimes, and 12% would rarely dismiss families from their practice if they wanted to spread out the primary series. Physicians reported using a variety of strategies in response to requests but did not think they were effective.

CONCLUSIONS

Virtually all providers encounter requests to spread out vaccines in a typical month and, despite concerns, most are agreeing to do so. Providers are using many strategies in response but think few are effective. Evidence-based interventions to increase timely immunization are needed to guide primary care and public health practice.

Clinical characteristics and antibiotic utilization in pediatric patients hospitalized with acute bacterial skin and skin structure infection

BACKGROUND

Hospitalizations for acute bacterial skin and skin structure infection (ABSSSI) in children are increasingly frequent, but little is known about antibiotic utilization. In adults, recent studies suggest substantial opportunity to reduce broad-spectrum antibiotic use and shorten therapy. We sought to determine whether similar opportunity exists in children.

METHODS

This was a planned secondary analysis of a pediatric cohort taken from a multicenter, retrospective cohort of patients hospitalized for ABSSSI between June 1, 2010, and May 31, 2012. The prespecified primary endpoint was a composite of 2 prescribing practices: (1) use of antibiotics with broad Gram-negative activity or (2) treatment duration >10 days.

RESULTS

One-hundred and two patients ≤ 18 years old were included: 43 had non-purulent cellulitis, 19 had wound infection or purulent cellulitis and 40 had cutaneous abscess. The median age was 5 years (range 45 days to 18 years). Clindamycin was the most frequently prescribed antibiotic during hospitalization (67% of cases) and at discharge (66% of cases). The median duration of therapy was 11 days (interquartile range 10-12) and was similar for all 3 types of ABSSSI. The primary endpoint occurred in 67% of cases, including broad Gram-negative therapy in 25% and treatment duration >10 days in 61%. By multivariate logistic regression, admission through an emergency department and management by a medical (vs. surgical) service were independently associated with the primary endpoint.

CONCLUSIONS

Children hospitalized for ABSSSI are frequently exposed to antibiotics with broad Gram-negative activity or treated longer than 10 days suggesting opportunity to reduce antibiotic use.
