Preprints with The Lancet is part of SSRN´s First Look, a place where journals identify content of interest prior to publication. Authors have opted in at submission to The Lancet family of journals to post their preprints on Preprints with The Lancet. The usual SSRN checks and a Lancet-specific check for appropriateness and transparency have been applied. Preprints available here are not Lancet publications or necessarily under review with a Lancet journal. These preprints are early stage research papers that have not been peer-reviewed. The findings should not be used for clinical or public health decision making and should not be presented to a lay audience without highlighting that they are preliminary and have not been peer-reviewed. For more information on this collaboration, see the comments published in The Lancet about the trial period, and our decision to make this a permanent offering, or visit The Lancet´s FAQ page, and for any feedback please contact preprints@lancet.com.

Background: The COVID-19 pandemic has had a profound impact on the 11 countries of the WHO South East Asia Region with substantial stress to health systems. We conducted a systematic review of studies that used quantitative and comparative approaches to assess the impact of the COVID-19 pandemic on the service provision of four NCDs (cancer, cardiovascular disease, chronic respiratory diseases, and diabetes) in the South East Asia region.
Methods: A systematic search was conducted in PubMed, Embase, MedRxiv, and WHO COVID-19 databases in December 2020. The quality of included studies was evaluated using the Joanna Briggs Institute Critical Appraisal Checklist and the ROBINS-I risk of bias tool. A narrative synthesis was conducted following the ‘synthesis without meta-analysis’ reporting guidelines. The review was registered with PROSPERO (CRD42020187629) and reported according to PRISMA guidelines.
Findings: Two review authors independently screened 5,397 records with 31 studies included, 26 which were cross-sectional in nature. The majority of studies (n=24, 77%) were conducted in India and 19 (61%) were single-site studies. 11/15 cancer studies examined disruptions to outpatient services, of which ten found a >40% reduction in service delivery post the onset of COVID-19 as compared to a pre-pandemic period. 10/12 cardiovascular disease studies examined disruptions to inpatient admissions, of which 9 found a reduction of 30% or greater compared to a pre-pandemic period. Two studies reported on disruption to respiratory disease services, finding a 78.9% reduction in diagnoses, and an 83% reduction in surgical management, respectively.
Interpretation: This review provides evidence that the COVID-19 pandemic has substantially disrupted the provision of health services for multiple NCDs, and in particular - cancer and cardiovascular disease, across numerous countries in the region. This is likely to have serious and potentially long-term downstream impacts on health and mortality of those living with or at risk of NCDs in the region.
Registration Details: The review was registered with PROSPERO (CRD42020187629) and reported according to PRISMA guidelines.
