The COVID-19 pandemic has caused significant shifts in patient care, including a dramatic shift from ambulatory visits together with a marked increase in the use of telemedicine. The Hemangioma Investigator Group (HIG) met via videoconferencing on March 22, 2020 to draft recommendations to help practitioners managing infants with infantile hemangiomas (IH) and subsequently reached consensus re: these recommendations. Ordinarily, recommendations such as those we are proposing undergo a rigorous process of development, peer review, and refinement. Due to the extraordinary circumstances we find ourselves in, we felt that there was an immediate need for recommendations regarding the evaluation and management of IH, particularly the initiation of systemic beta-blockers. The HIG has worked as a group for nearly 20 years and members have participated in many studies and several consensus statements. The statement was reviewed by all HIG members and consensus was reached regarding its recommendations.
This is a summary of recommendations with the full text to be submitted for expedited review and (we hope) publication shortly in Pediatric Dermatology. In deciding which infants with IH have higher-risk IH and may require treatment, please refer to the American Academy of Pediatrics (AAP) Clinical Practice Guidelines (CPG) which reviews risk stratification and consensus treatment recommendations. It has several useful graphics and tables to help guide referral and treatment decisions1.
The AAP guidelines also stress the importance of timing of intervention, when needed, as IH growth in the first weeks to few months of life can be very rapid. For higher risk IH, delaying treatment can result in poorer clinical outcomes. This is the central reason for this consensus statement, because delaying care until regular ambulatory visits are again the routine would undoubtedly result in increased morbidity for some patients with IH. Teletriage can be very useful in IH2. A validated tool for IH referral, the so-called IH Referral Score (IHReS), has been developed for use by primary care physicians but can also be used by specialists who may occasionally see IH but do not see them regularly enough to feel comfortable in risk-stratifying them3. Telemedicine as a way of delivering care to infants with IH has not been systematically studied so we have had to rely on current evidence and our collective personal experience for this statement.
Central to our consensus recommendations are decisions about initiation of oral or topical beta-blocker therapy via telemedicine. We reviewed current FDA/EMA monitoring guidelines, published clinical practice guidelines (CPG) and other relevant publications regarding initiation and monitoring of beta-blocker therapy to determine the appropriate utilization of telemedicine in managing IH. FDA/EMA guidelines call for in-office cardiovascular monitoring for up to 2 hours, however there is now a growing body of experience in healthy infants without health risk factors suggesting that cardiovascular complications from propranolol use are rare, and that prolonged monitoring during initiation has limited clinical utility4.
Our recommendations are summarized in Table 1 with an accompanying algorithm. It divides patients into 2 groups. Group 1 includes patients with characteristics conferring a standard risk. As such these infants can be considered as appropriate candidates for telemedicine initiation of oral or topical beta-blocker therapy. Group 2 includes patients with higher risk characteristics. For these infants initiation of medication via telemedicine, particularly systemic beta-blockers, should be avoided or used only in exceptional circumstances. This approach recognizes that there are features which may increase risk of beta-blocker therapies and/or IH co-morbidities which are important to recognize. Our recommendations for these evaluations for standard versus higher risk can also be applied to the use of topical timolol as it is widely used as an off-label therapy, but does have a potential for significant percutaneous absorption5.
There was broad consensus that in-person evaluation for new patients, particularly young infants, is still the best approach when it is feasible: physical examination can be more thorough and may provide a more accurate assessment of baseline status including subtle clues (such as duskiness) that may indicate impending ulceration, the presence of deeper hemangioma not evident with photographs or video without palpation, as well as responses to previously-initiated treatment. Other advantages of in-person assessment include more accurate assessment of weight, respiratory and cardiovascular examinations at the time, and the opportunity for face-to-face counseling and establishing rapport with families, which is particularly important for infants who need treatment, since the medications used are typically continued for many months or longer.
At the same time, there was also group consensus that visits via telehealth platforms could provide an alternative method of evaluation and treatment as long as safeguards are in place to minimize risks. Our recommendations are based upon first ensuring that there are no contraindications for therapy, documentation of a recent normal physical examination, and no signs or symptoms of active illness (Table) and thus are amenable to initiation of therapy through a process of limited physical examination coupled with virtual counseling and education about the natural history, treatment options, administration of medication and potential adverse reactions of therapy.
With or without telemedicine, all patients with IH need to carefully consider risks and benefits of any proposed treatment, discussion with families regarding treatment options, recommendations and information about possible adverse events from prescribed medications. In those cases where IH are still in the growth phase, we recommend particularly close follow-up, ideally within 1-2 weeks. Telemedicine can be particularly well-suited to these (typically brief) follow-up visits to assure that the IH is behaving as anticipated. Parents should be advised to reach out to practitioners in the context of changes in the IH (e.g. ulceration, ongoing growth, development/progression of functional impairment).
If the patient develops respiratory symptoms (e.g. cough, wheezing, respiratory distress), gastrointestinal symptoms (e.g. vomiting, diarrhea, decreased intake) or lethargy, medication should be temporarily discontinued and the prescribing practitioner should be notified. Comprehensive counseling and communication of potential risks and benefits of treatment are of paramount importance both for anticipatory guidance and to help minimize side effects. Online resources can be very helpful both in reinforcing education regarding the diagnosis of IH as well as specifics of treatment and possible side effects.
We hope that this information is useful to you in managing patients with infantile hemangiomas during this pandemic.

Group 1: Standard Risk (Inclusion Criteria): Checklist of baseline patient & IH characteristics: May consider telemedicine initiation of oral or topical beta-blocker therapy* as long as infant does not have additional features listed for Group 2
Group 2 High Risk (Relative or Absolute Exclusion Criteria): If one or more of these findings is present, in-person ambulatory evaluation is recommended unless local circumstances make this impossible prior to initiation of systemic beta-blocker therapy*
*In ordinary circumstances infants are being seen regularly for well-child visits by primary care providers, who weigh and measure infants and perform heart and lung examinations as a standard part of their care. If these examinations are not occurring due to disruptions in healthcare, it becomes much more difficult to ascertain whether there is a normal cardiovascular or pulmonary examination, if normal growth is occurring and other baseline characteristics. In such cases, decisions about initiating therapy must be made on a case-by-case basis.
**During this pandemic and other unusual circumstances, in-person visits may not be possible in a timely fashion. In these settings, triage and management decisions need to be made on a case by case basis, ideally in conjunction with relevant specialists as needed (e.g. ENT, cardiology, etc).
