Long-acting injectable antipsychotics (LAIs) are an essential tool in the treatment of patients with psychotic disorders, allowing for periods of stable drug plasma concentration and confirmed adherence.1 The current coronavirus disease 2019 (COVID-19) pandemic presents unique challenges for administering LAIs and requires a thoughtful and prospective approach in order to ensure continuity of psychiatric care while minimizing the risk of infection with COVID-19. Ideally, patients should be seen in person as infrequently as clinically prudent during this public health emergency; however, LAI administration necessitates direct physical contact between patient and clinician.
Patients with serious mental illness (SMI), who comprise the majority of individuals who receive LAIs, are at heightened risk for cardiovascular and pulmonary comorbidities. These factors are the primary reason the life expectancy of a patient with SMI is nearly 30 years shorter than that of the general population.2-5 The risk of health care workers becoming infected or inadvertently spreading COVID-19 is heightened when working with patients in group living environments (ie, a shelter or group home), who have both increased exposure and increased risk of further transmission.6 Additional patient populations, including older adults, immunocompromised individuals, and those with preexisting conditions, are at heightened risk for serious complications if they were to contract COVID-19.7,8
Thus, the questions of whether LAIs should be administered, and how to do so safely (both during the ongoing, acute phase of the pandemic as well as during the subsequent recovery period until the pandemic abates) need to be carefully considered. In this article, we provide concrete advice for clinicians and clinics on these topics, with the goal of maintaining patients’ psychiatric stability while protecting patients, health care workers, and the broader society from COVID-19 infection. Table 1 summarizes the questions regarding LAIs that clinicians need to address during this crisis. While we focus on outpatient care, inpatient teams should keep these considerations in mind if they are starting and discharging a patient on an LAI. More than ever, close collaboration and communication between inpatient and outpatient teams is critical.
Should an LAI be continued?
An important first step to approaching this challenge is to create a spreadsheet for all patients receiving LAIs. Focusing on a population-based approach is helpful to be systematic and ensure that no patients fall through the cracks during this public health emergency.9 Once all patients have been identified, the treatment team should review each patient to determine if continuing to administer the antipsychotic as an LAI formulation is essential, taking into account the patient’s current psychiatric status, historical medication adherence, potential severity and dangerousness of decompensation if nonadherent, and structures to support stability. For example, can a patient move in with family who can monitor medication adherence during the pandemic? Is it possible for the group home to assume medication administration? Additional consideration should be given to the living environment and health-vulnerability of the patient and the individuals living with them.
If the risk calculation does not point strongly towards a need for continuing the LAI, it may be prudent to temporarily transition the patient to the corresponding oral antipsychotic preparation. Table 2 lists all LAIs available in the United States and their approximate equivalent oral dosing. It is important to note that such transitions are not without clinical risk, to emphasize to the patient that the transition is intended as a temporary measure, and to discuss a proposed timeline for re-initiating the LAI. Also, emphasize to the patient and family that this transition does not diminish the previous reasoning for needing an LAI, but is a temporary measure taken in light of weighing the risks and benefits during a pandemic.
Which LAI should be administered?
If continuing the LAI is determined to be clinically necessary, consider switching the patient to a longer-acting preparation to maximize intervals between administrations and minimize the potential for infection. From a public health perspective, the longest clinically prudent interval between injections may be the most important consideration, provided the patient can receive a dose necessary to retain stability, and the LAI should be chosen accordingly. Deltoid injections may be able to be administered with reduced contact, or on a “drive-up” basis.10 Consider transitioning a patient who is receiving olanzapine pamoate to an alternate LAI or oral formulation, because the 3-hour observation period that is required after olanzapine pamoate administration is particularly problematic. While it may not be ideal to make medication changes during a pandemic, it is worth carefully weighing the patient’s stability and historical experience with other LAIs to determine if a safer/longer-spaced option is worth trying.11
We recommend only switching among similar antipsychotics (ie, risperidone to paliperidone), or between different preparations of the same drug (ie, Abilify Maintena to Aristada), if possible, as these are the lowest risk transitions with regards to relapse. Table 3 provides examples.
