Early impact of the COVID-19 pandemic on in-person outpatient care utilisation: a rapid review

Abstract

ObjectivesTo quantitatively assess the early impact of the COVID-19 pandemic on in-person outpatient care utilisation worldwide, as well as across categories of services, types of care and medical specialties.DesignRapid review.MethodA search of MEDLINE and Embase was conducted to identify studies published from 1 January 2020 to 12 February 2021, which quantitatively reported the impact of the COVID-19 pandemic on the amount of outpatient care services delivered (in-person visits, diagnostic/screening procedures and treatments). There was no restriction on the type of medical care (emergency/primary/specialty care) or target population (adult/paediatric). All articles presenting primary data from studies reporting on outpatient care utilisation were included. Studies describing conditions requiring hospitalisation or limited to telehealth services were excluded.ResultsA total of 517 articles reporting 1011 outpatient care utilisation measures in 49 countries worldwide were eligible for inclusion. Of those, 93% focused on the first semester of 2020 (January to June). The reported results showed an almost universal decline in in-person outpatient care utilisation, with a 56% overall median relative decrease. Heterogeneity across countries was high, with median decreases ranging from 10% to 91%. Diagnostic and screening procedures (−63%), as well as in-person visits (−56%), were more affected than treatments (−36%). Emergency care showed a smaller relative decline (−49%) than primary (−60%) and specialty care (−58%).ConclusionsThe provision of in-person outpatient care services has been strongly impacted by the COVID-19 pandemic, but heterogeneously across countries. The long-term population health consequences of the disruption of outpatient care service delivery remain currently unknown and need to be studied.PROSPERO registration numberCRD42021237366.

SARS-CoV-2 and COVID-19: A Narrative Review

“…The extra burden placed on General Practitioners in England as a result of the pandemic may part-explain the reduction in several diabetes health checks, the consequences of which are unclear but are likely to be detrimental ( 183 ) ( Table 12 ). Globally, there was a median 55.5% reduction (58% in the UK) of in-person outpatient care utilisation in visits, diagnostic/screening procedures, and treatment in emergency care, primary care and speciality care ( 184 ).…”

Cerebro-/Cardiovascular Collateral Damage During the COVID-19 Pandemic: Fact or Fiction?

“…During the first phase of the pandemic, healthcare utilization decreased dramatically, which affected primary, elective, and emergency/urgent care. 2 3 4 Cardiologists and neurologists observed a reduction of cerebro-/cardiovascular (CV) hospitalizations, with admissions for both acute coronary syndrome (ACS) and acute stroke (AS) declining sharply. 5 6 7 The scientific community hypothesized that this significant reduction was mostly attributable to fewer people going to the hospital for fear of becoming infected.…”

Are primary care virtual visits associated with higher emergency department use? A cross-sectional analysis from Ontario, Canada

“…The proportion of primary care delivered virtually varies by jurisdiction and practice and is influenced by factors such as reimbursement and overhead, patient and provider access to technology and infrastructure, provider access to personal protective equipment, provider health concerns, and patient and provider preference. [12][13][14][15][16][17] There have been concerns that in some practices, the proportion of virtual visits is too high resulting in an increase in other health system use. However, few studies have looked at the association between virtual primary care visits and other healthcare use.…”
