Caring for Patients at a COVID-19 Field Hospital

COVID-19 field hospitals must be prepared to respond effectively to decompensating patients. In our experience, effective RRTs provide a standard and reproducible approach to patient emergencies. In the conventional hospital setting, these teams consist of clinicians who can be called on by any healthcare worker to quickly assess deteriorating patients and intervene with treatment. The purpose of an RRT is to provide immediate care to a patient before progression to respiratory or cardiac arrest. RRTs proliferated in US hospitals after 2004 when the Institute for Healthcare Improvement in Boston, Massachusetts, recommended such teams for improved quality of care. Though studies report conflicting findings on the impact of RRTs on mortality rates, these studies were performed in traditional hospitals with ample resources, consultants, and clinicians familiar with their patients rather than in resource-limited field hospitals.^4-13 Our field hospital has found RRTs, and the principles behind them, useful in the identification and management of decompensating COVID-19 patients.

An approach to managing decompensating patients in a COVID-19 field hospital can be considered in four phases: identification, assessment, resuscitation, and transport. Referring to these phases, the first case shows opportunities for improvement in resuscitation and transport. Although decompensation was identified, the patient was not transported to the triage bay for resuscitation, and there was confusion when trying to obtain the proper equipment. Additionally, EMS awaited the patient in the triage bay, while he remained in his cubicle, which delayed transport to an acute care hospital. The second case shows opportunities for improvement in identification and assessment. The patient had signs of impending decompensation that were not immediately recognized and treated. However, once decompensation occurred, the RRT was called and the patient was transported quickly to the triage bay, and then to the hospital via EMS.

In our experience at the BCCFH, identification is a key phase in COVID-19 care at a field hospital. Identification involves recognizing impending deterioration, as well as understanding risk factors for decompensation. For COVID-19 specifically, this requires heightened awareness of patients who are in the 2nd to 3rd week of symptoms. Data from Wuhan, China, suggest that decompensation occurs predictably around symptom day 9.^14,15 At the BCCFH, the median symptom duration for patients who decompensated and returned to a hospital was 13 days. In both introductory cases, patients were in the high-risk 2nd week of symptoms when decompensation occurred. Clinicians at the BCCFH now discuss patient symptom day during their handoffs, when rounding, and when making decisions regarding acute care transfer. Our team has also integrated clinical information from our electronic health record to create a dashboard describing those patients requiring acute care transfer to assist in identifying other trends or predictive factors (Appendix D).

Although RRTs are designed to activate when an individual patient decompensates, they should fit within a larger operational framework for patient safety. Our experience with emergencies at the BCCFH has yielded four opportunities for learning relevant to COVID-19 care in nontraditional settings (Table). These lessons include how to update staff on clinical process changes, unify communication systems, create a clinical drilling culture, and review cases to improve performance. They illustrate the importance of standardizing emergency processes, conducting frequent updates and drills, and ensuring continuous improvement. We found that, while caring for patients with an unpredictable, novel disease in a nontraditional setting and while wearing PPE and working with new colleagues during every shift, the best approach to support patients and staff is to anticipate emergencies rather than relying on individual staff to develop on-the-spot solutions.
