Designing a psychological preparedness toolkit for healthcare workers in the wake of COVID-19: A Singapore perspective

Highlights • The COVID-19 pandemic is a tensile stress test of the robustness of healthcare emergency preparedness measures.• Fear of the unknown, uncertainty, and anxiety are risk factors for burnout and trauma in healthcare workers in the wake of a pandemic.• A reliable and accurate psychological preparedness toolkit for healthcare workers is important in reducing stress and anxiety.• A psychological preparedness toolkit may incorporate mental health, organizational theories and health professions education principles.


Introduction
The COVID-19 pandemic has proven to be a tensile stress test for Singapore, as the collective consciousness of the Severe Acute Respiratory Syndrome (SARS) still lingers. On the psychological front, healthcare worker (HCW) survivors still recall the emotional stress owing to the fear of an unknown disease, public stigma, and the grim realities of mortality (Kwek et al., 2004;Maunder et al., 2003). Notably, caring for fellow HCWs as patients was a unique yet challenging emotional experience (Maunder et al., 2003). These challenges underscore the need to provide psychological support to frontline HCWs. However, this provision is not without its challenges due to the lack of shared experiences from lay mental health providers, and the competing demands between patient care and staff support (Duan and Zhu, 2020).
Learning from the experience of SARS, COVID-19 pandemic preparedness now extends beyond medical and systemic aspects of care. It recognizes the psychological support of HCWs as an essential strategy in ensuring a robust workforce with a sustained ability to provide safe care (Kang et al., 2020). Therefore, psychiatrists play a crucial role in education and advocacy during a pandemic, considering the multifarious psychological implications of COVID-19 (Tandon, 2020).
A Psychological Preparedness Toolkit for HCWs was designed for Singapore's National Centre for Infectious Diseases to prepare HCWs who were about to be deployed to crucial COVID-19 care areas. Its objective was to provide realistic depictions of frontline work, which would be unfamiliar to HCWs from different care settings and levels of experience. This toolkit preceded hospital-wide psychological support measures, such as the nomination of welfare officers and psychological first aid training. The toolkit content comprised four main categories: (i) expected emotional responses, (ii) changes in the work environment, (iii) support measures, and (iv) anticipated effects on mental health.

A toolkit in the infodemic era: addressing anxiety arising from hearsay
The paradigm shift defining COVID-19 apart from the era of SARS lies in the ease and speed in how information is obtained, consumed, and disseminated with technology and social media. As such, the toolkit avoided replication of existing content such as stress management strategies that were readily available from reputable sources.
With the rapid sharing of information across various digital media, those receiving information from various sources may doubt about the credibility of hearsay (Vosoughi et al., 2018). The toolkit provided a reliable source of advice and practical coping strategies from the pioneer cohort of HCWs who served in COVID-19 care areas. An illustrative and informative example is the commonly-encountered discomfort of Personal Protective Equipment (PPE) and HCWs learning to reduce mask abrasions with emollients.

Challenges unique to healthcare across borders
The ethno-geographic diversity of Singapore's healthcare workforce and its implications were illustrated by the Malaysian border lockdown enforced within 48 h of its announcement (The Star Online Internet Malaysia and The Star, 2020). Given that HCWs form a significant part of the 300,000 people crossing the Malaysia-Singapore border daily (The Straits Times Internet Singapore and The Straits Times, 2016), those who chose to continue working in Singapore were stranded, and accommodation and alternative work arrangements became issues that required immediate attention. The toolkit acknowledged these challenges that occurred outside of healthcare and provided tips on using social media and telecommunications to foster connectivity with the workers' families.

Encouraging self-monitoring and self-help
The toolkit included the Burnout Measure (short version) (Malach-Pines, 2005), a widely used self-reported appraisal of burnout because of its intuitive questions and ease of use, to encourage periodic mental health check-ins. The hospital's employee assistance program helplines were appended to nudge distressed persons to seek help.

Supervisor toolkits: organizational health principles in outbreak management
Inclusion of principles of organization theory in the context of COVID-19 management aided supervisors in the evaluation of employee behaviors, and in identifying risk factors for burnout and disengagement. Specific sources of stress, namely biosecurity measures, loss of autonomy, and perceived lack of control, guided the identification of pain points that may affect employee well-being.

What is the moral of their stories? Narration as an impactful way to convey information
Storytelling is recognized as a powerful educational strategy in health professions education and is often employed as a means of information sharing, engagement, and promotion of citizen participation (Haigh and Hardy, 2011). Personally-narrated stories of frontline HCWs were weaved into the toolkit to highlight essential learning points. The creation of relatable and easily identifiable content overcomes issues with cognitive overload and information fatigue [ Table 1].

Conclusion
The psychological preparedness toolkit is an emergency educational tool borne out of exigent circumstances. Given the needs of the day, the toolkit was designed as an informative just-in-time strategy, focusing on needs-related training, easy accessibility, and highly-identifiable content. Timely and effective psychological preparedness interventions are necessary to ensure the sustainability of a resilient workforce that should not only be able to mount a sprint response, but also possess the tenacity to run a long-drawn marathon of a global pandemic.
