Counseling families about social media

- Jennifer Middleton, MD, MPH

Counseling at well child visits about media use can easily fall by the wayside with so many other important topics to discuss. Our office's electronic health record (EHR) has several template options to choose from for well child exams that each include age-appropriate anticipatory guidance topics, but none of them, at any age, include media use. Adding that prompt may become imperative, especially given the American Academy of Pediatrics' (AAP) Use of Media by School-Aged Children and Adolescents guideline. A recent AFP issue reviewed this new guideline and reminds us of the importance of making time to discuss media use with families.

The AAP encourages physicians to screen for problems related to media use, such as sexting, cyberbullying, problematic internet use, and Internet gaming disorder, in children and adolescents. A recent survey of Texas high schoolers found that 28% of adolescents had texted a naked picture of themselves ("sexting"); in this study, teen girls who sexted were at higher risk of engaging in high risk sexual behavior. The authors of this study suggest asking all teens if they have ever sent, received, or been asked to text a naked picture and also note that the majority of teens are quite uncomfortable with participating in sexting.

The AFP review of this guideline notes that cyberbullying can bring "social, academic, and health concerns" for both the victim and the bully. Several validated scales for screening both bullying victims and perpetrators can be found in this CDC document; although none explicitly mention social media use, several questions are vague enough to potentially include cyberbullying.

Validated scales do exist for screening for problematic internet use and Internet gaming disorder. The 18-item Problematic and Risky Internet Use Screening Scale (PRIUSS) can help identify adolescents and adults with problematic internet use. Many adolescents and young adults with problematic internet use also have depression, social anxiety, and/or attention deficit disorder, so a positive PRIUSS should prompt exploration of these other possible diagnoses. The Internet Gaming Disorder Test (IGDT-10) is a 10 question screen for Internet gaming disorder.

Besides screening for these 4 conditions, the AAP encourages physicians to discuss boundary setting regarding places and times where media use is and is not appropriate. Parents should role model appropriate media use, such as keeping electronic devices (including televisions) outside of the bedroom. Parents also should discuss online safety with their children, though some parents feel unprepared to do so; the AAP has a list of tips for parents here. There's also an AFP By Topic on Health Maintenance and Counseling that includes additional resources for well child (and adult) visits.

No data yet exists showing that screening for these conditions positively influences any patient-centered outcomes, but their associations with mental illness and risky behaviors is convincing enough for me to incorporate them into my well child visits. I'm going to get started by asking our EHR leadership to add "media use" to our anticipatory guidance templates. What step will you take to facilitate conversations about media use with families?

Self-monitoring doesn't improve control of type 2 diabetes

- Kenny Lin, MD, MPH

"Have you been checking your sugars?" I routinely ask this question at office visits involving a patient with type 2 diabetes, whether the patient is recently diagnosed or has been living with the disease for many years. However, the necessity of blood glucose self-monitoring in patients with type 2 diabetes not using insulin has been in doubt for several years.

A 2012 Cochrane for Clinicians published in AFP concluded that "self-monitoring of blood glucose does not improve health-related quality of life, general well-being, or patient satisfaction" (patient-oriented outcomes) and did not even result in lower hemoglobin A1C levels (a disease-oriented outcome) after 12 months. In their article "Top 20 Research Studies of 2012 for Primary Care Physicians," Drs. Mark Ebell and Roland Grad discussed a meta-analysis of individual patient data from 6 randomized trials that found self-monitoring improved A1C levels by a modest 0.25 percentage points after 6 and 12 months of use, with no differences observed in subgroups. Based on these findings, the Society of General Internal Medicine recommended against daily home glucose testing in patients not using insulin as part of the Choosing Wisely campaign.

Still, the relatively small number of participants in trials of glucose self-monitoring, and the persistent belief that it could be useful for some patients (e.g., recent type 2 diabetes diagnosis, medication nonadherence, changes in diet or exercise regimen), meant that many physicians have continued to encourage self-monitoring in clinical practice. In a 2016 consensus statement, the American College of Endocrinology stated that in patients with type 2 diabetes and low risk of hypoglycemia, "initial periodic structured glucose monitoring (e.g., at meals and bedtime) may be useful in helping patients understand effectiveness of medical nutrition therapy / lifestyle therapy."

In a recently published pragmatic trial conducted in 15 primary care practices in North Carolina, Dr. Laura Young and colleagues enrolled 450 patients with type 2 non-insulin-treated diabetes with A1C levels between 6.5% and 9.5% and randomized them to no self-monitoring, once-daily self-monitoring, or once-daily self-monitoring with automated, tailored patient feedback delivered via the glucose meter. Notably, about one-third of participants were using sulfonylureas at baseline. After 12 months, there were no significant differences in A1C levels, health-related quality of life, hypoglycemia frequency, health care utilization, or insulin initiation. This study provided further evidence that although glucose self-monitoring may make intuitive sense, it improves neither disease-oriented nor patient-oriented health outcomes in patients with type 2 diabetes not using insulin.

Adding an antibiotic to uncomplicated I&Ds may improve outcomes

- Jennifer Middleton, MD, MPH

Adding an oral antibiotic after incision and drainage of an uncomplicated skin abscess has been found, to date, to not improve clinical outcomes. The American College of Emergency Physicians (ACEP) even has a Choosing Wisely recommendation to this effect. A study published last week, however, found differently: adding an antibiotic after incision and drainage (I&D) of small skin abscesses resulted in better clinical healing.

The study authors prospectively enrolled 505 adults and 281 children at several sites across the United States who presented to urgent care clinics, Emergency Departments (EDs), and outpatient care sites with small skin abscesses (no greater than 5 cm in diameter for adults, no larger than 3 cm for children under 1 year of age, no larger than 4 cm for children aged 1-8 years) and randomized them to receive, after incision and drainage, either 10 days of clindamycin, trimethoprim/sulfamethoxazole (TMP/SMX), or placebo. 81.7% and 83.1% of the participants who received clindamycin or TMP/SMX, respectively, had a clinical cure 10 days after completing antibiotics, compared with only 68.9% of participants who received a placebo (95% confidence intervals 78.3-87.9, 76.8-86.7, and 62.9-74.9, respectively). When analyzed separately, the researchers found that clindamycin was more effective in the pediatric participants compared to TMP/SMX, while the difference between cure rates for adults for these 2 antibiotics was not significant.

New infections in the 30 days following treatment were more common in the placebo group than either antibiotic group; clindamycin was more effective than TMP/SMX in preventing recurrent infection, especially in pediatric participants. Adverse events were more common in the clindamycin group, though, and most commonly consisted of diarrhea and nausea; these were described as "mild or moderate and resolved without sequelae." 1 hypersensitivity reaction to TMP/SMX was described.

This study's findings contradict common practice and the ACEP's Choosing Wisely recommendation. A closer look at the references cited in the ACEP's Choosing Wisely recommendation, however, demonstrate that the evidence to date regarding treatment of uncomplicated skin abscesses has been a bit meager. They include a smaller randomized control trial (RCT) from 2010 that found placebo equivalent to TMP/SMX in 161 pediatric patients treated in EDs for uncomplicated abscesses; an RCT from 1985 that enrolled 50 adults and found no difference in clinical improvement between those treated with cephradine (a first-generation cephalosporin) and placebo; and, a 2011 cross-sectional study that examined differences in antibiotic prescribing habits across 3 separate pediatric EDs but did not examine clinical outcomes.

Additionally, the Infectious Diseases Society of America's 2014 Practice Guideline for the Diagnosis and Management of Skin and Soft Tissue Infections includes a "strong" recommendation against using antibiotics in uncomplicated skin abscesses but describes the quality of the evidence supporting this recommendation as "low." The more robust design of this new study, with its large number of participants and breath of geographic sites, makes its findings difficult to dismiss. It also builds on a 2016 RCT which found that, in care sites with a high prevalence of methicillin-resistant Staphylococcus aureus (MRSA), adding TMP/SMX to incision and drainage improved clinical cure rates in adults and teens with uncomplicated skin abscesses compared to placebo.

Given all of the attention on inappropriate antibiotic use these last few weeks on the blog, it's admittedly a bit tough to digest a study that suggests adding antibiotic treatment to a condition that didn't previously warrant it. It will be interesting to see if other researchers attempt to replicate this result or, perhaps, perform a systematic review of all of the data on this topic.

Will this study change how you care for patients after incision and drainage of an uncomplicated skin abscess?

Strategies to limit antibiotic resistance and overuse

- Kenny Lin, MD, MPH

According to a report from the Centers for Disease Control and Prevention (CDC), more than 2 million Americans become infected with antibiotic-resistant bacteria each year, leading directly to at least 23,000 deaths and contributing indirectly to thousands more. Antibiotic resistance occurs in the community, in long-term care facilities, and in hospital settings. Another CDC report on preventing healthcare-associated infections (also discussed in this AFP article) identified six high-priority antibiotic resistance threats: carbapenem-resistant Enterobacteriaceae, methicillin-resistant Staphylococcus aureus (MRSA), extended-spectrum beta-lactamase-producing Enterobacteriaceae, vancomycin-resistant Enteroccocus, multidrug-resistant Pseudomonas, and multidrug-resistant Acinetobacter.

In a 2014 editorial, "Antibiotic resistance threats in the United States: stepping back from the brink," Dr. Steven Solomon and Kristen Oliver from the CDC identified three strategies that family physicians can use to limit antibiotic resistance: 1) Preventing infections through immunizations, standard infection control practices, and patient counseling; 2) Reporting unexpected antibiotic treatment failures and suspected resistance to local or state health departments; and 3) Prescribing antibiotics more carefully. Unfortunately, inappropriate antibiotic prescribing (also known as antibiotic overuse) is common in primary care, particularly for patients with acute viral respiratory tract infections.

Antibiotic overuse is a multifaceted problem with many potential solutions. On Sunday, July 9th at 7 PM Eastern, Dr. Jennifer Middleton (@singingpendrjen) and I (@kennylinafp) will be taking a deep dive into the evidence on the most effective strategies to curb prescribing of unnecessary antibiotics.

Twitter chats: 21st century CME

- Jennifer Middleton, MD, MPH

Being active on Twitter can have many advantages for family physicians. Following journals like AFP (@AFPJournal) can make it easy to keep up with the latest medical studies and news. With individual tweets limited to 140 characters, Twitter chats provide a way to explore a particular issue more in-depth and build connections among people with common interests. Increasingly, they can also be a way to increase physician knowledge and even obtain continuing medical education (CME) credit.

Typically, Twitter chats occur at a scheduled time, last for about an hour, and are moderated by one or a few members of the hosting organization. The topic for discussion is determined in advance, and the moderators usually prepare questions to ask participants throughout the hour. Participants can tweet responses to the questions - and to each other's responses - during the hour, and the conversation can be reviewed later by searching for the chat's hashtag. You can see an example of a Twitter chat here.

Several medical journals and organizations are using Twitter chats (or virtual journal clubs, as some journals prefer to call them) to engage with their members. The Annals of Family Medicine and the Society of Teachers of Family Medicine host regular Twitter chats covering a variety of clinical and educational topics pertinent to Family Medicine. In other specialties, Journal of the American Geriatrics Society, American College of Chest Physicians, Annals of Emergency Medicine, and the Society of Hospital Medicine all host or have hosted Twitter chats.

Using Twitter for medical education can have tangible benefits. Medical students who participated in Twitter activities relating to biomedical science studies had higher grades than those who did not. Medical students who participated in Twitter activities related to gross anatomy classes reported better communication with faculty, higher morale, and less anxiety. A general surgery program used a competitive Twitter microblogging project to improve their residents' in-training exam scores. An Australian research group found that online CME using Twitter and other social media platforms was perceived as more cost effective for physicians compared to attending live CME conferences.

Last year, AFP hosted its first Twitter chat, and this year, on July 9, we'll host our first Twitter chat for CME credit on the topic of antibiotic overuse. You can claim 4 hours of CME credit for participating; the chat will be 1 hour, and the additional 3 hours are allotted for the preparation time to read the articles. You can download the articles we'll be covering, learn more about the basics of a Twitter chat, and register here. If you have questions about how to get involved, you can tweet @AFPJournal or email afpedit@aafp.org.

What benefits or barriers do you see to using Twitter for CME?

Start collecting community vital signs in your practice

- Kenny Lin, MD, MPH

Primary care physicians and educators are increasingly recognizing the usefulness of assessing social determinants of health (defined by the Centers for Disease Control and Prevention as conditions in the places where people live, learn, work, and play) during health care encounters. A recent National Academy of Medicine discussion paper described the Accountable Health Communities Screening Tool, developed by the Center for Medicare and Medicaid Innovation to identify and address five domains of health-related social needs: housing instability, food insecurity, transportation difficulties, utility assistance needs, and interpersonal safety. Since 2011, students at Morehouse School of Medicine and Georgia State University College of Law have participated in an interprofessional medical-legal curriculum; surveys suggested that medical students who completed the curriculum were more likely to screen for social determinants of health and refer patients to legal resources. In March, the American Academy of Family Physicians (AAFP) launched its Center for Diversity and Health Equity, whose planned activities will include

- evaluating current research on the social determinants of health and health equity;
- promoting evidence-based community and policy changes that address the social determinants of health and health equity; and
- developing practical tools and resources to equip family physicians and their teams to help patients, families, and communities.

In an editorial in the June 1 issue of American Family Physician, Drs. Lauren Hughes and Sonja Likumahuwa-Ackman add another potential dimension for action on social determinants of health by introducing the concept of "community vital signs." In contrast to data collected directly from patients, the authors write,

Community-level data are acquired from public data sources such as census reports, disease surveillance, and vital statistics records. When geocoded and linked to individual data, community-level data are called community vital signs. Community vital signs convey patients' neighborhood health risks, such as crime rates, lack of walkability, and presence of environmental toxins. ... This enhanced knowledge about where patients live, learn, work, and play can help physicians tailor recommendations and target clinical services to maximize their impact. Rather than simply recommending that a patient eat better and exercise more, care teams can connect patients to a local community garden, low-cost exercise resources (e.g., YMCA), or neighborhood walking groups.

To get started using community-level data to improve patient care and population health, family physicians can consult The Practical Playbook and the AAFP's Community Health Resource Navigator. The editorial also provides a suggested five-step process for incorporating community vital signs into clinical practice.
