Disaster response
Advancing disaster medicine and global health in times of pandemic
Worldwide hardships due to COVID-19 have revealed opportunities for improvement. Disaster education, telemedicine, knowledge sharing, and resource allocation have been highlighted as such areas. In an August 2020 publication, Hart et al. argue, “Every hospital needs a Disaster Medicine physician now” (Hart et al. “Why Every US Hospital Needs a Disaster Medicine Physician Now”).
Every physician must be prepared to be the expert in times of disaster. A survey of U.S. medical students showed that despite few respondents (<27%) feeling adequately educated, >90% are willing to respond to a natural disaster or a pandemic (Kaiser et al. Disaster Med Pub Health Prep. 2009;3[4]:210-16). While natural disasters have increased by almost 35% since the 1990s, a robust approach to disaster education is not routinely implemented across the fields of medicine, nursing, allied health, and health administration (Freebairn. World Disasters Report 2020: Executive Summary. 2020 ed. IFRC. ). Notably, disaster education provides opportunities for multidisciplinary team-building where learners build a foundation of knowledge together. While no ideal educational model has been fully adopted, high-quality educational opportunities include National Disaster Life Support Foundation courses, SALT triage, and ATLS (Homer et al. Prehospital and Disaster Medicine).
Telemedicine has emerged as a very effective means of disaster support through both direct patient encounters and provider education. Tele-triage used to delineate patients requiring urgent hospitalization from those who can be managed at home has proven effective in areas with limited health care facilities (World Health Organization. Coronavirus disease.). Knowledge sharing opportunities from organizations like Project ECHO have allowed for >368,000 learners from 146 countries to exchange information during >8,000 learning sessions (Project ECHO COVID-19 response.).
Physicians of all specialties should continue to develop skills in triage, surge capacity management, ethical/legal issues surrounding disasters, organizational interoperability, and telemedicine, and emphasize skills to ensure their own personal protection.

Telehealth and postpandemic care
Telehealth is the use of electronic information and telecommunication technologies to provide care when the physician and the patient are not in the same place. Telehealth has been available for 40 years. The COVID-19 pandemic forced health care providers, systems, and patients to quickly adapt to virtual audio and visual visits, new documentation parameters, billing, and reimbursement structures. Emergency rules have removed the barriers to adoption of home-based diagnostics and virtual visits. It is expected that 20% to 30% post-pandemic care will be provided via telehealth.
Telehealth is particularly beneficial in providing counseling services or managing chronic illnesses, such as COPD and heart failure. There has been an explosion of monitoring devices both wearable and implantable. Some devices, which monitor PA pressure, have been shown to reduce heart failure hospitalizations and all-cause hospitalizations (Shavelle DM, et al. Circ Heart Fail. 2020;13: e006863). Studies have been conducted on home spirometry and oximetry devices in post-lung transplant, ILD (Russell AM et al. Am J Respir Crit Care Med. 2016 Oct 15; 194[8]:989-997), and CF patients (Compton M et al. Telemed J E Health . 2020 Aug;26[8]:978-84). As we move forward, we will have to ascertain what data acquisition is relevant and develop processes to address it in real time.
In this changing landscape of health care delivery, we can anticipate an increase in virtual visits and a trend toward e-consults, which will necessitate further advancements in remote monitoring and assessment and will require us to adopt new practice models.

The rise in lung transplant for older patients
Over the past 20 years, there has been a dramatic increase in lung transplantation in elderly patients, with wide variability in age limit amongst transplant centers. The number of recipients over the age of 65 has risen from 6.9% in 2004 to 29.6% in 2016 in the United States, and 2.6% to 17% internationally. There is a number of factors driving this increase; the prevalence of advanced lung disease with increasing age, advances in targeted therapies to treat cystic fibrosis, an increased willingness of centers to perform transplants in older patients, and the 2005 revision of the Lung Allocation Scoring System (Courtwright A, Cantu E. J Thoracic Dis. 2017:9[9]:3346-51).
In the past, outcomes posttransplant for elderly patients have been conflicting in single-center studies. More recently, Hayanga et al. found no difference in survival up to 1 year between individuals 60-69 and those over 70 (J Heart Lung Transplant. 2015;34[2]:182-88). Mosher et al., however, found the median survival dropped from 4.64 years for patients aged 65-69 to 3.07 years for patients ≥74 (J Heart Lung Transplant. 2021;40[1]:42-55). Notably, older recipients were more likely to be readmitted at 30 and 90 days, and more likely to be discharged to an inpatient rehabilitation facility following transplant (McCarthy et al. J Heart Lung Transplant. 2017;36:S115; Tang et al. Clin Transplant. 2015;29:581-587).
The use of transplant in elderly patients comes with many concerns regarding neurocognitive status, frailty, and other comorbidities, all of which must be rigorously tested prior to consideration(Biswas R et al. Ann Thorac Surg. 2015;100:443-51). Recipient age, creatinine level, bilirubin level, steroid use at the time of transplant, and hospitalization at the time of transplant were associated with increased mortality (Mosher et al. J Heart Lung Transplant. 2021;40[1]:42-55). Further research is warranted in this evolving area.

Will the new pulmonary hypertension hemodynamic classification temper the PH ‘sex-paradox’?
Older and contemporary PH registries have consistently shown that PH predominantly affects women ~2 to 3.5 times than men, with female patients having better survival compared with men (Kozu K et al. Heart Vessels. 2018;33[8]:93), a fact attributed to better RV function in female than male subjects. This PH sex-paradox denotes that while estrogen leads to increased susceptibility to PH, it appears to confer better outcomes after PH develops due to improved RV function, since RV dysfunction is a strong predictor of poor outcomes in PH. Multiple preclinical studies have described how estrogen provides protective effects on the RV (Cheng TC et al. Am J Physiol Heart Circ Physiol. 2020;319:H1459; Frump AL et al. Am J Physiol Lung Cell Mol Physiol. 2015;308:L873).
The recent recommended updates to the hemodynamic definition reflect acknowledgment of irrefutable evidence that even mildly elevated mPAP (between 19 and 24 mm Hg) is associated with increased morbidity and mortality based on consistent data from pulmonary arterial hypertension (PAH) as well as from other forms of PH [Simonneau G et al. Eur Respir J. 2019;(Jan 24);53(1):1801913). With incorporation of the updated definition that more accurately captures the disease state and its progression, an unaddressed question still remains as to how the new classification will change PH treatment algorithm and outcomes in women compared with men. Setting the definition of PH at a mPAP of 20 mm Hg not only better represents the typical patients with PH in practice, such as those with PH due to left-sided heart disease (Group 2) or PH associated with chronic lung disease (Group 3), but incorporates the preclinical pathologic disease state of PH, in which symptoms may not be evident (Maron BA, et al. Circulation. 2016;133:1240). In adhering to the new PH definition, will earlier diagnosis across the spectrum of all individuals with PH before RV dysfunction has developed improve outcomes for all those afflicted with PH and equalize outcomes between men and women? As future studies continue to investigate the direct effects of sex hormones on the RV and dissect the mechanisms leading to the sex differences in RV function in PH, a pre-clinical diagnosis in all PH patients, particularly male patients with Group 2/3 disease, may mitigate some of the previously observed advantages of estrogen on outcomes in PH.
