Category of response

Key steps

Initial rapid response

• Incident command structure established [5]

• SARS-CoV-2 PCR testing capacity secured

• Point-of entry screening at clinical facilities established

• Nonurgent and out-of-region transplants deferred

• Hospital no-visitor policy implemented

• Telehealth transplant consultations replaced face-to-face visits

• Work-from-home policy for nonessential staff implemented

Operational changes

• Additional inpatient rooms converted to negative pressure

• Clinic and triage hours extended to preserve inpatient resources

• Videoconference rounding as feasible

• Additional back-up physician coverage secured

• Staff deemed at higher risk of COVID-19 morbidity reassigned

• Biweekly videoconferences with program leadership

• Internal memoranda to faculty regularly updated and distributed

SARS-CoV-2 testing by PCR

• All symptomatic patients

• Asymptomatic patients:

     • At the start of the pretransplant evaluation

     • Before initiating the preparative regimen

     • Weekly after HCT until discharge to local physician

     • Prior to any procedure

Prioritization of transplants

• Considered risks related to the underlying malignancy (Table 2) and comorbidity

• Prioritized local over out-of-region patients

• Generally proceeded with HCT if long-term survival estimate > 20%

Donor considerations

• Unrelated donors: cryopreserve all products

• Related donors: negative SARS-CoV-2 testing within 48 h of start of patient conditioning permitted use of fresh donor product

Clinical trials

• Temporary pause of all phase 1 and 3 trials

• Phase 2 trials with potential benefit to patients continued accrual

• Study visits conducted by telehealth

• Ancillary studies paused
