Implications and ContributionsDuring the COVID-19 pandemic, telemedicine use is increasing without practice guidelines specific to adolescent health. This study summarizes obstacles to the implementation of telemedicine for adolescents and proposed solutions. Observations made during this process have implications for the continued use of telemedicine to improve health-care access beyond the current pandemic.

See Related Editorial on p.145The Coronavirus Disease 2019 (COVID-19) pandemic is a rapidly evolving public health crisis. Uptake of telemedicine has been one response used by providers to continue caring for patients while minimizing risk of exposure or transmission of COVID-19 \[[@bib1], [@bib2], [@bib3], [@bib4]\]. The Centers for Medicare and Medicaid Services defines telemedicine as two-way, live communication between the patient and provider at a distant site including audio and video equipment \[[@bib5]\]. This may occur with or without the assistance of peripheral medical examination devices (e.g., electronic stethoscope) and can augment but should not fully replace in-person medical visits \[[@bib6],[@bib7]\]. Telemedicine has been increasingly recognized in recent years as a tool to improve access to health care \[[@bib8], [@bib9], [@bib10], [@bib11]\]. Despite successful expansion of telemedicine in some areas, persistent barriers to widespread implementation include patient and provider acceptance, technical connectivity challenges, infrastructure to support Health Insurance Portability and Accountability Act (HIPAA) compliant care, and unavoidable deviations from clinical standards of care \[[@bib7]\]. Thus, the COVID-19 pandemic has challenged clinicians to rapidly determine how to provide high-quality care while addressing the public health needs of the community. The appropriate response may vary by patient population, specialty, practice setting, and local availability of resources. For providers caring for adolescents and young adults (AYAs), the scramble to care for this vulnerable population in the midst of a pandemic raises questions about quality of care, limitations of telemedicine, and challenges with confidentiality that are yet to be fully understood.

Despite opportunities for improved access to care, telemedicine has not been widely implemented or studied within the field of adolescent medicine. Telemedicine practice guidelines are established for general pediatrics \[[@bib12]\] and adolescent and pediatric mental health care, \[[@bib13]\] but there are no telemedicine guidelines specific to adolescent medicine. Ethical and legal complexities remain, including concerns over privacy and data security, inequity in access to technology and technological knowledge, and questions regarding effects on the doctor-patient relationship \[[@bib7],[@bib14],[@bib15]\]. Given this population's unique access-to-care issues (e.g., sexual/reproductive health, mental health, and substance use) and the wide developmental variation in health-care needs and literacy, additional research and guidelines are needed to incorporate telemedicine into AYA care.

Some precedents do exist for remote provision of key components of adolescent medicine including online platforms for reproductive health services \[[@bib16],[@bib17]\] and mental health telemedicine for the treatment of eating disorders \[[@bib18],[@bib19]\]. Telemedicine for medical monitoring in eating disorders care is emerging out of necessity during the COVID-19 pandemic \[[@bib3]\].

Despite limited evidence and lack of guidelines for AYA telemedicine, the COVID-19 pandemic has necessitated its rapid adoption in AYA-serving practices. The University of California San Francisco (UCSF) Adolescent and Young Adult Medicine clinic provides primary and subspecialty care to local urban AYAs and specialty care to patients from communities across Northern California. This study reports on our clinic's rapid transition to audiovisual telemedicine without peripheral devices to decrease the number of in-person clinic visits in response to COVID-19 and describes novel observations, challenges, and opportunities for innovation.

Clinical context {#sec1.1}
----------------

UCSF's Adolescent and Young Adult Medicine Clinic is embedded in an urban academic medical center. The clinic was established in 1974 and serves 12- to 26-year-old patients. In 2019, the clinic served 1,715 unique patients over 4,195 clinic visits. Patients are 26% male and 32% publicly insured. The clinic provides full-spectrum interdisciplinary AYA care including primary care for AYAs with complex medical conditions, management of attention and mood disorders, sexual and reproductive health care, eating disorder care, and addiction treatment.

Intervention {#sec1.2}
------------

In the setting of the COVID-19 pandemic, our practice sought to maximize AYA access to health care while maintaining social distancing. As a result, we rapidly implemented the use of telemedicine in all aspects of our practice. This required coordination between providers, clinical support staff, and clerical staff (see [Table 1](#tbl1){ref-type="table"} : Personnel Involved in Implementation). All providers were trained to use Zoom (Zoom Video Productions, Inc, San Jose, CA), \[[@bib20]\] a HIPAA-compliant audiovisual tool, for telemedicine purposes within one week of our initial faculty meeting on COVID-19 (see [Table 2](#tbl2){ref-type="table"} : Timeline).Table 1Personnel involved in implementationTitleRole**Providers** Nurse practitioners (NP)\

Nursing and administrative staff created new protocols for remote triage, scheduling, and patient check-in. Because virtual visits required patients to have access to the electronic medical record (EMR) patient portal, clerical staff had to develop new workflows to be able to enroll minors and their proxies remotely while still maintaining confidentiality and obtaining appropriate written permissions. A member of the clinical faculty met with support staff daily throughout telemedicine implementation to identify challenges and facilitate communication between providers and staff. The first two weeks of the intervention focused on addressing logistical challenges to EMR patient portal enrollment, patient scheduling, utilization of the telemedicine platform, and streamlining communication between providers, clinical support staff, and clerical support staff. By week two, providers began identifying challenges and lessons learned in practicing telemedicine for general adolescent health care, reproductive health, eating disorders, and addiction treatment as highlighted below. We received a letter of exemption from the UCSF Institutional Review Board for this publication.

Results {#sec2}
=======

The number of telemedicine visits in our practice increased from zero to 80 per week as of March 30, 2020 ([Figure 1](#fig1){ref-type="fig"} ). While the percentage of provider telemedicine visits increased from 0% to 97%, the number of overall clinic visits did not decline when compared with that one year before (337 visits in March 2019 vs. 332 visits in March 2020), and no-show rates were comparable. The clinic billed 518 relative value units in March 2020, compared with 480 relative value units billed in March 2019. Owing to delays in insurance company adjudications, we cannot report actual March 2020 revenue generated.Figure 1Clinic visits per week. AYA clinic visit types (telemedicine visit, provider visit in clinic, or nurse-only visit in clinic) by week in March 2019 compared to March 2020, illustrating telemedicine visits from zero per week to 56 per week by the second week of March this year. By the last week in March, more visits were conducted via telemedicine than total clinic visits in the same week one year earlier.

Overall, providers noted that telemedicine seemed acceptable to AYAs who generally had competence with electronic communications platforms and welcomed the convenience of meeting with providers remotely. Providers reported only two visits that were not completed because of technical issues. When needed, providers were able to integrate certified medical interpreters directly into telemedicine visits. Generally, patients arrived on time, and the structure of telemedicine encounters combined with our initial problem-focused visits led to timely clinic sessions which were well received by providers and patients.

Providers identified several common barriers to telemedicine across all clinical domains. In some cases, privacy and confidentiality were challenges given the provider's inability to establish a quiet and private environment for the patient as they would in an office visit. In response, providers encouraged AYAs to use headphones, used yes/no questions, and leveraged the Zoom chat function to allow patients to type replies to questions while limiting disclosure to household members in close proximity. With these interventions, providers only reported seven appointments in which the scope of care was overtly limited because of patient privacy concerns. Lower socioeconomic status compounded privacy challenges because of crowded living conditions. While some providers were also concerned that patients with limited socioeconomic means might not have access to the electronic devices needed for telemedicine (smart phone, tablet, or computer), all patients in our clinic were able to access an appropriate device for their appointments.

Implementation efforts also revealed barriers to telemedicine related to limited provider comfort with clinical decision-making in the absence of a complete physical examination or laboratory data. Providers explored evidence-based practices for treating common ailments such as suspected uncomplicated urinary tract infections or strep throat with clinical scoring and assessment methods based on limited objective data. In addition, numerous providers reported discomfort with asking patients to provide on-camera views of certain body parts as part of their physical examination because of limitations in patient privacy as well as provider-perceived impropriety (see [Reproductive health](#sec2.3){ref-type="sec"} section).

In addition to these overarching issues, the practice also identified actual and potential barriers to telemedicine ([Tables 3](#tbl3){ref-type="table"} and [4](#tbl4){ref-type="table"} , respectively) and solutions specific to each of its main clinical domains.Table 3Identified telemedicine barriers and solutionsBarriersSolutions**General issues** Limits to patient privacy and confidentiality•Use of ZOOM chat feature•Patient use of earphones with provider use of yes/no questions Limited provider comfort with sensitive examinations on telemedicine•Patients can upload relevant photographs via EMR patient portals•Practices and national organizations will need to develop guidance about best practices related to the use of sensitive examinations in telemedicine. Limited provider comfort with clinical decision-making in the absence of physical examinations and point-of-care testing.•Point-of-care testing can be conducted in local laboratories or with nursing visits•Providers can share evidence-based guidelines of clinical scoring modalities possible with telemedicine examinations. Inability to assess recommended anthropomorphic data for annual preventive visits•Consider augmentation with nursing visits to collect vitals, high, weight, vision screening, hearing screening, STI screening, and blood work (lipids, HIV screening, and so on). Clinical encounters no longer colocated with interdisciplinary colleagues•Fully train social workers and registered diaticians to use telemedicine software.•Establish internal referrals to social work and dietitian staff with scheduling assisted by clinic staff.**Mental health** Need for ongoing screening and assessments of mood symptoms.•EMR-based administration of PHQ-9 and GAD-7 before telemedicine visit.**Reproductive health** Limited provider comfort with sensitive examinations on telemedicine•Patient can take still photos of visible lesions and submit them via the EMR patient portal•Practices and national organizations will need to develop policies about best practices related to the use of genitourinary examinations in telemedicine. Need for in-person encounters for LARCs, Papanicolau smears, and acute pelvic complaints•Hybrid model is needed with telemedicine visits to triage acute symptoms and in person visits for diagnosis and treatment.**Eating disorder care** Inability to assess recommended anthropomorphic data for eating disorder visits•Train family members to collect weights at home.•Use hospital satellite clinics to collect vital signs.•Partner with local PCPs to collect weights and vital signs.•When possible, partner with therapists to trend weights from therapy visits. Inability to assure parent privacy while disclosing patient weight or dietary recommendations.•Have parents and patient call in from separate devices so that one can be "removed" from the visit to facilitate confidential discussions.[^2]Table 4Anticipated barriers and identified opportunitiesAnticipated barriersFuture opportunitiesPatients might not have an appropriate device to engage in telemedicine•All patients in our practice had access to an acceptable phone or computer device.•Patients may have access to computers or tablets at school, through other community programs, or via family members.•Centers for Medicare and Medicaid Services and private payers could expand reimbursements for telephone only encounters•Consultations could occur directly in a primary care providers' office with clinic equipmentTechnology literacy gap within a family may lead to decreased engagement with caregiver (e.g., an adolescent may be comfortable with telemedicine, but the parent is not)•Initial consultations could be completed in office with training for family members.•Technical support could be provided in the form of online tutorials or phone support.Patients may reject telemedicine because of lack of connection with providers or limits of care.•As telehealth was well received, it could be used to reduce geographic and travel-related financial barriers to care (gas, missed work, and so on) and expand subspecialty care for wider populations.Language barriers could limit engagement in telemedicine•Standard phone interpreting services can be directly integrated in the telemedicine platform.Reimbursements may be low or unavailable for telemedicine•State, federal, and private payor expansions of telemedicine coverage were ongoing during the pandemic and may provide opportunities for future telemedicine reimbursement

General adolescent and young adult health care {#sec2.1}
----------------------------------------------

Our initial rollout of telemedicine focused on general AYA acute health complaints that did not require respiratory triage for COVID-19 evaluation. Issues that were particularly straight forward to treat via telemedicine included follow-up for established problems such as chronic headaches, dermatologic issues, and some musculoskeletal complaints. Initially, we did not offer well care visits because of our inability to monitor height, weight, blood pressure, vision, and hearing as recommended by Bright Futures, although we later established a protocol for obtaining at-home weights for those patients with a scale \[[@bib28]\]. In addition, vaccines and screening for HIV, sexually transmitted infections (STIs), and dyslipidemia could only be completed in person with the help of nurses or phlebotomists. However, many aspects of adolescent and young adult care recommended by Bright Futures were possible to implement via telemedicine including screening for depression, substance use, psycho-social development, and general anticipatory guidance \[[@bib28]\].

Another limitation of our initial telemedicine rollout was that our social workers and dietitians were not available in real-time as they had been in the clinic's former practice model. Telemedicine visits began with one registered dietitian. An additional dietitian and social worker were included by the second week of implementation. To facilitate internal referrals, we created a shared list of patients requiring consultation with these providers in the EMR. Ongoing efforts aim to further integrate our social work and dietitian colleagues into our telemedicine practice.

Mental health {#sec2.2}
-------------

Providers identified that medical management of mood disorders and maintenance of attention deficit hyperactivity medications were all easily managed via telemedicine. We used built-in EMR questionnaires, including the Patient Health Questionnaire 9 and the Generalized Anxiety Disorder 7, which patients could complete before their appointments to screen for and monitor mood or anxiety disorders. The rapid implementation of telemedicine for mental health services was critical as we saw an influx of college-aged youth returning home abruptly from campuses and requiring mental health support and medication refills because of loss of college-based providers or new onset of acute stress responses secondary to the pandemic. One challenge providers faced was how to appropriately manage medications for conditions typically managed by psychiatrists (e.g., antipsychotics, mood stabilizers, benzodiazepines). We chose to bridge patients with prescriptions as we facilitated appropriate local referrals.

Reproductive health {#sec2.3}
-------------------

Despite limitations to physical examinations via telemedicine, providers identified contraception counseling and provision of combined hormonal contraceptives (pills, patches, and vaginal rings) as feasible for telemedicine with a plan to reassess blood pressure at the patients' next in-person clinic visit given the low occurrence of clinically significant hypertension with these methods. In addition, consults for dysmenorrhea, menorrhagia, and oligomenorrhea were completed via telemedicine with supporting visits for blood work or imaging as indicated. Specific to reproductive health, providers expressed concern about the possibility of reproductive coercion given limitations to patient privacy via telemedicine.

Despite the ease of telemedicine for some contraception visits, many other reproductive health issues required physical examinations (e.g., suspicion for pelvic inflammatory disease) or laboratory tests (e.g., STI screening, testing, and treatment; HIV screening and Pre-Exposure Prophylaxis). Likewise, in-person visits are essential to the provision of long-acting reversible contraception (intrauterine devices and the implant), injectable medroxyprogesterone, treatment of ascending pelvic infections, and Papanicolaou smears. Patients requiring these services were offered appointments during the clinic's abbreviated in-person sessions. We also transitioned collection of pregnancy tests, STI screening, HIV testing, and Pre-Exposure Prophylaxis monitoring serologic tests to nursing or laboratory visits either at UCSF or commercial laboratories.

In some cases, when physical examinations for reproductive health complaints were possible via telemedicine, providers in our practice struggled with the propriety of virtual genital or breast examinations. For example, one patient described a classic genital herpetic lesion by history, but the provider did not feel it was appropriate to ask the patient to point his camera at the lesion and instead asked the patient to come to clinic for an in-person visit. Other providers chose to complete similar examinations via telemedicine or ask patients to submit photos of their lesions via the EMR patient portal.

Eating disorders {#sec2.4}
----------------

The medical monitoring of eating disorders includes regular assessment of weight, vital signs, dietary history, electrolyte monitoring, and coordination with the patients psychotherapist \[[@bib29]\]. Given the need for regular anthropomorphic measurements for these patients, providers expressed particular concern about transitioning these patients to telemedicine. As such, we collaborated with our psychiatry colleagues to refine a protocol for family members to calibrate home scales and take blind weights before telemedicine visits. In other cases, therapists or primary care providers measured weights and vital signs and forwarded these data to our team. Finally, when a patient was clearly engaged in concerning behaviors (e.g., increased restricting, purging, over exercising) or the provider, therapist, patient, or family member had a high index of suspicion for medical deterioration, the patient was asked to come in for one of the clinic's limited in-person sessions for measurement of weight, orthostatic vital signs, and any indicated blood work (e.g., electrolyte monitoring). When admission was required due to vital sign instability, it could be coordinated from that visit.

Providers noted that our eating disorder patients particularly benefitted from the convenience of telemedicine as they are referred to our clinic from a much wider geographic range than our primary care patients. By working with our hospital's satellite clinics, local primary care providers, and therapists, we were able to spare these patients and their families the financial and time burdens of travel to our clinic, in addition to minimizing potential transmission of COVID-19 between communities.

Our providers identified unique challenges to telemedicine in this patient population. Concerns about privacy arose again, including concerns of patient distress related to overhearing specific weight numbers or nutrition interventions that providers would otherwise discuss confidentially with parents or guardians in an in-person clinical setting. Providers encouraged parents to use headphones in these encounters. Conversely, telemedicine created flexibility for some families, allowing increased parental participation in medical visits (e.g., among parents with separate households or for working parents).

Addiction treatment {#sec2.5}
-------------------

The UCSF Youth Outpatient Substance Use Program is embedded in the Adolescent & Young Adult Medicine Clinic and provides treatment to youth with opioid use disorder (OUD) and other substance use disorders. Initially, we limited these telemedicine visits to established patients. We expanded care to new patients after March 31, 2020, when the Drug Enforcement Administration in partnership with the Substance Abuse and Mental Health Services Administration issued guidelines allowing appropriately-credentialed providers to admit and treat new patients with OUD and to prescribe buprenorphine using telemedicine platforms without initial in-person assessments during the COVID-19 public health emergency \[[@bib26]\]. As a program funded by Substance Abuse and Mental Health Services Administration, Youth Outpatient Substance Use Program is legally required to complete structured intakes that include demographic, diagnostic, physical health, and mental health information \[[@bib30]\]. To ensure that new patients completed federally required intake interviews, our program support staff began conducting these via Zoom© before each patient's first physician telemedicine visit. We asked that, whenever possible, youth and their parents log in to visits from different devices or have access to separate private spaces to facilitate separate but co-occurring confidential meetings with clinicians and social workers. For youth in need of psychiatric assessments for comorbid disorders, our providers also transitioned to telepsychiatry. As most components of the clinical opiate withdrawal scale can be assessed via video connection, we plan to conduct buprenorphine inductions using telemedicine for youth who can enlist a loved one to provide support. We will offer in-clinic inductions to youth who do not have access to a support person.

Discussion {#sec3}
==========

This study describes one AYA medicine practice's experiences in quickly implementing telemedicine without peripheral examination devices in response to a pandemic. Many observations are widely applicable to other AYA medicine practices, while some may be unique to our group. Because our practice is based in San Francisco, where strict shelter-in-place mandates were announced early in the COVID-19 pandemic (March 16, 2020), \[[@bib31]\] we adopted changes in our practice earlier and more rapidly than many other practices in the United States. This rapid shift required us to continuously reassess balancing adherence to social distancing while preserving our commitment to high-quality AYA care. Given the dearth of telemedicine guidelines specific to AYA, these changes were uncomfortable for our providers but necessary in the face of unprecedented circumstances.

Our rapid transformation to a primarily telemedicine practice was facilitated by multiple factors including institutional support for telemedicine as well as access to the necessary technology and training for providers and clerical staff in their adjusted roles. Not all AYA practices have the same systems-level supports in place, and different creative strategies will be required to resolve barriers to telemedicine.

State and national policies regarding telemedicine are undergoing rapid changes. Centers for Medicare and Medicaid Services has modified payment policies to encourage telemedicine \[[@bib24]\], and private payors are following suit, announcing elimination of copayments for telemedicine visits \[[@bib25]\]. While payment and privacy laws vary by state, many states have reduced policy barriers to telemedicine \[[@bib32]\]. Similarly, the Department of Health and Human Services announced that it will not penalize the use of HIPAA noncompliant video chat applications for telemedicine during the COVID-19 emergency \[[@bib33]\]. In other countries, telemedicine implementation is also being fast-tracked with adjustments to privacy laws and systems-level supports \[[@bib2]\]. While expansion of AYA telemedicine continues under these emergency policy changes, it is unclear if this expansion would be sustainable should these be reversed. For example, practices may no longer be able to effectively bill for telemedicine, clinicians currently using HIPAA noncompliant applications may need systems-level supports to transition to different platforms, and addiction medicine providers may no longer be able to prescribe medications for treatment of OUD using only telemedicine.

Serving AYAs through telemedicine poses many unanswered questions. For AYA primary care, the extent to which health supervision via telemedicine is appropriate remains unclear. While many aspects of routine AYA preventive care can be done via telemedicine, some components are not feasible \[[@bib28]\]. It remains to be seen how advancing technologies (e.g., wearables or smart phone accessories) and the shifting culture of adolescent medicine might overcome some of these challenges. A lack of research or practice guidelines on telemedicine for AYAs leaves providers in this field with patients who largely have access to the necessary technology \[[@bib34]\] and are likely eager to take advantage of virtual visits \[[@bib35]\] but with no clear evidence or recommendations on applying telemedicine in this population. This study was limited to anecdotal provider experiences and short-term data. More research is needed to understand the patient and family experience of AYA telemedicine.

Along with the possibilities offered by telemedicine, it is crucial to consider its current limitations and how they can be addressed. Barriers to telemedicine still exist for AYAs who lack access to internet or required technology or who have no private place to conduct a visit (e.g., due to homelessness or overcrowding). In addition, it is well documented that young adults have worse clinical outcomes than adolescents on a variety of health issues, and it remains to be seen if telemedicine may impact these disparities \[[@bib36]\]. Furthermore, as we push the limits of what can be done via telemedicine, our patients' safety must remain paramount. For example, AYAs may live in unsafe conditions involving abuse or violence, where discussions during a telemedicine visit at home could put them in danger or they may not be able to safely disclose all their concerns. In-person clinic visits must remain available for patients, and providers should use in-person appointments if they suspect telemedicine may be inappropriate for these reasons.

As noted, our providers struggled with the propriety of genital examinations via telemedicine. Strategies for collaborative decision-making with patients about limitations of telemedicine examinations balanced with patient inconvenience and risk (e.g., risk of infection in the COVID-19 pandemic) will need to be explored through further research with patients and providers. Best practices in this regard are also likely to have implications for sexual maturity ratings for adolescent preventative health-care visits.

There is particularly urgent need to better understand the efficacy of telemedicine for the medical management of patients with eating disorders and addiction. While telemedicine has the potential to expand access to specialty care for both, research is needed to understand the safety, efficacy, and acceptability of telemedicine for these disorders. For eating disorder care, research is needed to assess the accuracy of home weights, hospitalization rates, and long-term recovery outcomes when eating disorders are managed via telemedicine. AYA subspecialists can expand access to care by collaborating with primary care providers via teleconsultation \[[@bib7]\].

There is a sense that many of the changes that we have described here are not just temporary responses, but rather they represent a "new normal." While we are by no means proposing that telemedicine for AYAs will replace seeing patients in person, the field can look at this quick shift to telemedicine as an opportunity to reach our patient population in new ways, both in this time of crisis and beyond.
