COVID-19-positive medical/psychiatric units

A patient who tests positive for COVID-19 and has an acute psychiatric illness or is suffering from acute substance withdrawal is a unique challenge in all settings. It may be an onerous task, especially in low-resource countries, to manage such patients in a medical intensive care unit. The staff are ill-equipped to handle psychiatric emergencies, and there may be a risk of violence on the part of the patient. Team management by a combination of both medical and psychiatric units is required in such cases. The patient would need admission in a restrictive environment such as an in-patient psychiatric unit and at the same time would need intensive care back-up if available.^{Reference Fagiolini, Cuomo and Frank2} COVID-19-positive psychiatric patients would ideally need input from psychiatrists and internal medicine experts working in the same unit. At any point in time either the psychiatric disorder or the medical disorder could take priority and there may be instances where both conditions should be treated simultaneously. Some patients need isolation and primary medical treatment, whereas others need medical monitoring while the primary management is delivered by psychiatrists. Many patients will need individual psychotherapy, occupational therapy and help from a psychiatric social worker, so all these professions should ideally contribute to the staffing of such units.^{Reference Bojdani, Rajagopalan, Chen, Gearin, Olcott and Shankar3}

PPE and nursing staff training

A problem faced by many LMICs is the shortage of personal protective equipment (PPE) needed to protect staff who are monitoring patients held in isolation during the acute phase of the COVID-19 infection. If there is joint care from physicians and psychiatrists, the entire psychiatric unit will need to be trained in its effective use. That would include not only wearing and removal but also the disposal of PPE, as well as basic training in infection control and sanitisation procedures.^{Reference Tomas, Kundrapu, Thota, Sunkesula, Cadnum and Mana4}

The nursing staff of a joint medical/psychiatric unit would need to be trained from a medical and psychiatric point of view. Nurse:patient ratios will have to be monitored (as in a psychiatric unit) and a combination of medical and psychiatric nurses would be in joint overall charge. The nursing staff would need both to monitor patients for their mental state and to undertake medical observations, if they are managing high-risk patients who are COVID-19 positive. This will be demanding, so it is important to allow for relief and breaks from wearing PPE. They should have access to rest periods between duties.^{Reference Shao, Shao and Fei5}

Restraint and discharge guidelines

The ‘COVID-19-positive medical/psychiatric unit’ will require guidelines to be put in place on the restraint of violent patients. There will be a need for staff to wear PPE when they perform such interventions. Additional guidelines should indicate when a patient who is COVID-19 negative and medically fit may be discharged. They might be transferred to a non-COVID-19 psychiatric unit in the same centre or to a long-term rehabilitation unit so that psychiatric care can be continued. Keeping all this in mind, it would be prudent for the general hospital psychiatric units that form the backbone of psychiatric care in LMICs to take up the challenge of establishing COVID-19-positive medical/psychiatric units in the same hospital to facilitate better care for these subsets of patients.^{Reference Xiang, Zhao, Liu, Li, Zhao and Cheung6}

Patient-specific considerations

While running a COVID-19-positive medical/psychiatric unit there is also a need for all the staff involved to be trained in ethical considerations. It would be important to ensure that at all times there is no ethical violation or human rights violation from the patient's perspective. Many psychiatric patients may not be capable of giving consent to treatment, so an evaluation of their insight into the procedures will need to be carried out. A legal representative may have to be consulted in such cases.^{Reference De Sousa, Mohandas and Javed7}

Many psychiatric patients (unlike other patients with COVID-19 infections) will need help from a psychosocial point of view to combat the dual stigma they may face (COVID-related plus mental illness-related). They may need assistance to find employment post-discharge, supervised medication, decent housing and sound social support.^{Reference Mukhtar8}

Two other important points also need consideration. There could be interactions between the drugs used in the management of COVID-19 and psychotropic medication. Vigilance will be required to watch for psychiatric side-effects caused by drugs used in the management of COVID-19.^{Reference Zhang, Zhou, Liu and Hashimoto9} It is also vital to bear in mind the possibility that emergent psychiatric symptoms could be of neuropsychiatric origin due to the COVID-19 infection, resulting from the massive release of cytokines that sometimes occurs in that condition. A cytokine storm can have psychiatric manifestations.^{Reference Mehta, McAuley, Brown, Sanchez, Tattersall and Manson10}

Service implications

Where possible, we recommend the establishment of COVID-19-positive joint medical/psychiatric units in LMICs, although there are various challenges in achieving this and in providing psychiatric care in such settings. Many LMICs simply lack sufficient psychiatric establishments and staff to provide such joint care. In such countries it is imperative to put in place structures by which medical staff who are caring for COVID-19-positive patients with mental health problems can obtain (online) support from experts who understand the issues involved.
