The COVID-19 pandemic has disrupted the delivery of mental health services globally, particularly in many lower-income and middle-income countries (LMICs), where the substantial demands on mental health care imposed by the pandemic are intersecting the already fragile and fragmented care systems. The global concern regarding the psychosocial consequences of COVID-19 has led major funding bodies and governments to increasingly call for proposals to address these effects. Although assessments of high-quality systematic data that address the immediate psychosocial problems of the pandemic are pertinent,1Holmes EA O'Connor RC Perry VH et al.Multidisciplinary research priorities for the COVID-19 pandemic: a call for action for mental health science.Lancet Psychiatry. 2020; 7: 547-560Summary Full Text Full Text PDF PubMed Scopus (3689) Google Scholar the generation of evidence that advances the objectives of global mental health within the context of the pandemic is also vital.2Saxena S Belkin G Knowledge gaps in implementing global mental health activities.Glob Ment Health (Camb). 2017; 4: e23Crossref PubMed Google Scholar In the past decade, global mental health researchers have made considerable progress in the development and testing of innovative approaches within mental health care. Trials have shown the clinical effectiveness and cost-effectiveness of mental health interventions, despite the large gaps in care for mental disorders globally.3Javadi D Feldhaus I Mancuso A Ghaffar A Applying systems thinking to task shifting for mental health using lay providers: a review of the evidence.Glob Ment Health (Camb). 2017; 4: e14Crossref PubMed Google Scholar, 4Patel V Saxena S Lund C et al.The Lancet Commission on global mental health and sustainable development.Lancet. 2018; 392: 1553-1598Summary Full Text Full Text PDF PubMed Scopus (1375) Google Scholar To address shortages in service delivery, the 2018 Lancet Commission on global mental health and sustainable development4Patel V Saxena S Lund C et al.The Lancet Commission on global mental health and sustainable development.Lancet. 2018; 392: 1553-1598Summary Full Text Full Text PDF PubMed Scopus (1375) Google Scholar identified mental health as an essential component of universal health coverage. Among its key messages, the Commission re-emphasised the call to scale up mental health care and recognised the potential of digital health to increase access to mental health services.4Patel V Saxena S Lund C et al.The Lancet Commission on global mental health and sustainable development.Lancet. 2018; 392: 1553-1598Summary Full Text Full Text PDF PubMed Scopus (1375) Google Scholar The case for repeating these key messages is compelling as mental health professionals devise urgent strategies to address the mental health consequences of COVID-19. How can we create notable actions from existing strategies in global mental health to improve coverage of mental health services in the coming months? Two successful global mental health strategies are relevant to research on mental health services in the context of COVID-19. The first is task shifting—the use of trained lay health workers to deliver health care in non-specialist settings. With regard to the data on global care gaps for mental disorders, the situation is least favourable in LMICs.4Patel V Saxena S Lund C et al.The Lancet Commission on global mental health and sustainable development.Lancet. 2018; 392: 1553-1598Summary Full Text Full Text PDF PubMed Scopus (1375) Google Scholar Task shifting has led to the success of many innovative mental health services, with evidence of promise in low-resource settings, despite several implementation challenges limiting their use.3Javadi D Feldhaus I Mancuso A Ghaffar A Applying systems thinking to task shifting for mental health using lay providers: a review of the evidence.Glob Ment Health (Camb). 2017; 4: e14Crossref PubMed Google Scholar Increasing pressure on health systems resulting from COVID-19 highlights the need to re-examine task shifting, to further investigate how it can be widely implemented to improve the access and reach of mental health services. Task shifting can be used to address the urgent need to build a provider base in developing countries, given the flexible workforce it can provide for service delivery at the community level, within homes, schools, work places, and care centres.5Kohrt BA Asher L Bhardwaj A et al.The role of communities in mental health care in low-and middle-income countries: a meta-review of components and competencies.Int J Environ Res Public Health. 2018; 151279Crossref PubMed Scopus (165) Google Scholar These settings can serve as service outlets for mental health promotion and awareness programmes, and for service provision via community engagement with trained lay mental health providers.5Kohrt BA Asher L Bhardwaj A et al.The role of communities in mental health care in low-and middle-income countries: a meta-review of components and competencies.Int J Environ Res Public Health. 2018; 151279Crossref PubMed Scopus (165) Google Scholar However, in implementing task shifting, important aspects are to build on past successes by recognising its limits as a system intervention,3Javadi D Feldhaus I Mancuso A Ghaffar A Applying systems thinking to task shifting for mental health using lay providers: a review of the evidence.Glob Ment Health (Camb). 2017; 4: e14Crossref PubMed Google Scholar and give attention to implementation barriers to scale-up and sustain the use of successful approaches. Essentially, to optimise uptake of new or existing evidenced-based mental health innovations, adopting and adapting task-shifting strategies within health systems and implementation research frameworks will be necessary. Such approaches will allow targeted problems to be identified, studied, and addressed within some or all of the complex service levels within the six building blocks of the health system (service delivery, health workforce, information technology, medical products, financing, and governance and leadership), which will be crucial to wide-scale implementation and coverage. The second strategy is the use of digital health technology to strengthen health systems. Widespread adoption of mobile phones in LMICs has led to their increasing use for health interventions. Although evidence supporting large-scale adoption of virtual interventions for mental health care in LMICs is sparse,6Naslund JA Aschbrenner KA Araya R et al.Digital technology for treating and preventing mental disorders in low-income and middle-income countries: a narrative review of the literature.Lancet Psychiatry. 2017; 4: 486-500Summary Full Text Full Text PDF PubMed Scopus (297) Google Scholar and high-income countries (HICs) currently dominate digital innovations,1Holmes EA O'Connor RC Perry VH et al.Multidisciplinary research priorities for the COVID-19 pandemic: a call for action for mental health science.Lancet Psychiatry. 2020; 7: 547-560Summary Full Text Full Text PDF PubMed Scopus (3689) Google Scholar the COVID-19 pandemic has led to increasing global adoption of virtual care to reduce the risk of infection among health workers.7Webster P Virtual health care in the era of COVID-19.Lancet. 2020; 395: 1180-1181Summary Full Text Full Text PDF PubMed Scopus (518) Google Scholar Furthermore, despite several questions surrounding digital innovation, even in HICs, their potential to increase access and coverage in hard-to-reach areas calls for more research on their effectiveness in LMICs.6Naslund JA Aschbrenner KA Araya R et al.Digital technology for treating and preventing mental disorders in low-income and middle-income countries: a narrative review of the literature.Lancet Psychiatry. 2017; 4: 486-500Summary Full Text Full Text PDF PubMed Scopus (297) Google Scholar Mobile phones can assist the delivery of quality services by facilitating access to training, supervision, and support among care providers, and making health records available remotely.6Naslund JA Aschbrenner KA Araya R et al.Digital technology for treating and preventing mental disorders in low-income and middle-income countries: a narrative review of the literature.Lancet Psychiatry. 2017; 4: 486-500Summary Full Text Full Text PDF PubMed Scopus (297) Google Scholar A basic mobile phone function such as text messaging can have a range of uses, from delivering bulk health information on prevention and promotion programmes, to uses in supporting patient recovery even in cases of severe mental illness such as psychosis.8Ben-Zeev D Buck B Kopelovich S Meller S A technology-assisted life of recovery from psychosis.NPJ Schizophr. 2019; 5: 15Crossref PubMed Scopus (19) Google Scholar Additionally, International Telecommunication Union reports have indicated high usage of mobile internet networks in LMICs (>91% 3G users and >78% Long Term Evolution or Worldwide Interoperability for Microwave Access network users), meaning online video calls and mobile phone applications can be used to support patient care in real time.9Kale N Jacob I Laux T Kataria R Jain Y Gogia P Managing major psychiatric illnesses through tele-consultation in a secondary care setting in rural India.Ann Glob Health. 2016; 82: 323-324Crossref Google Scholar The availability of internet data from mobile networks can also allow for follow-up care and empowerment of patients and their families during the recovery process via various online platforms.

However, despite the incentives to increase uptake of digital health, an important caveat is the possible lack of access for vulnerable people needing health care. To address this limitation, the Lancet Commission on global mental health recommended adoption of digital interventions alongside traditional treatments, rather than as replacements.4Patel V Saxena S Lund C et al.The Lancet Commission on global mental health and sustainable development.Lancet. 2018; 392: 1553-1598Summary Full Text Full Text PDF PubMed Scopus (1375) Google Scholar The psychosocial burden of COVID-19 will become increasingly evident in the coming months as the effects of social measures such as physical distancing, loneliness, death of friends and family members, and job losses manifest. Efforts to respond to these mental health needs present researchers with an important opportunity to build on what we know and advance progress in achieving the mental health objectives of universal health coverage.
