Telehealth: The future is now in allergy practice.

To the Editor:

We read with interest the Editorial by Portnoy et al, where the authors, in the face of the current pandemic, very elegantly summarize the main advantages and limitations of virtual appointments. Telemedicine (TM) has the potential to help enabling patients to get the supportive care they need, and the use of this tool is increasing. We agree with the authors that a pandemic is an unfortunate occurrence but it is also an opportunity to set up an infrastructure for providing care using TM, which can continue to be used in the future to provide convenient and cost-effective care to patients. TM has been successfully applied to several respiratory conditions, and it can be an alternative to traditional in-person visits for the treatment and management of asthma.

Worldwide coronavirus disease-2019 (COVID-19) brought a lot of challenges in health care. In our country, the state of emergency was declared on March 19, 2020, bringing strict measures to nonurgent patient inflow in our hospital. Within a pandemic risk-stratified context, knowing that allergic conditions can be misinterpreted or exacerbated by viral infections and social distancing might increase anxiety, telehealth was considered as an option to face-to-face contacts. For the first time, in 2 weeks, real-time video appointments were implemented in our allergy center.

Patients were invited to be consulted in virtual visits, including first appointments (12% of the total). We noted an increasing agreement to virtual visits (Figure 1 ), followed by a decrease when emergency state was over on May 2. For these consultations, patients only had to have internet connection and a smartphone, tablet, or computer with a camera and microphone. All the prescriptions and treatment plans were also sent virtually. When indicated we still received the more severe patients as in-person visits, in particular patients with specific needs, including desensitization to chemotherapy.

To assess satisfaction and willingness to repeat or recommend virtual appointments, we conducted 2 surveys, one for patients with asthma (n = 40) who had participated in virtual consultations during this pandemic (with the collaboration of the Portuguese Association of Asthmatics) and another one for the allergy specialists of our center (n = 21).

In summary, communication between patients and doctors was not considered to be compromised in virtual appointments (>92% agreement in both surveys). Most patients rated the virtual visit as good/very good (93%). Ninety-five percent of the providers considered that their performance was not affected, but 43% had some difficulties in the management of their patients, mainly related to the lack of physical examination. Seventy percent of patients would adhere to these appointments outside COVID-19, and 93% would recommend it to their family and friends. Doctors consider that this way of practicing medicine has a future in our health care system (93%), benefiting mild-to-severe patients (81%), as well as those living far away from the hospital (19%). Less than 5% of the patients needed to be referred to do in-person visits.

Telemedicine is an already validated tool.1, 2, 3, 4 The COVID-19 pandemic allowed us to implement telehealth-focused processes to provide safe and convenient patient care, and both patients and allergists seem willing to continue to use it.
