Impact of COVID-19 Pandemic on Air Quality: A Systematic Review.

ABSTRACT: With the emergence of the COVID-19 pandemic, several governments imposed severe restrictions on socio-economic activities, putting most of the world population into a general lockdown in March 2020. Although scattered, studies on this topic worldwide have rapidly emerged in the literature. Hence, this systematic review aimed to identify and discuss the scientifically validated literature that evaluated the impact of the COVID-19 pandemic and associated restrictions on air quality. Thus, a total of 114 studies that quantified the impact of the COVID-19 pandemic on air quality through monitoring were selected from three databases. The most evaluated countries were India and China; all the studies intended to evaluate the impact of the pandemic on air quality, mainly concerning PM10, PM2.5, NO2, O3, CO, and SO2. Most of them focused on the 1st lockdown, comparing with the pre- and post-lockdown periods and usually in urban areas. Many studies conducted a descriptive analysis, while others complemented it with more advanced statistical analysis. Although using different methodologies, some studies reported a temporary air quality improvement during the lockdown. More studies are still needed, comparing different lockdown and lifting periods and, in other areas, for a definition of better-targeted policies to reduce air pollution.

Project description:ObjectivesThe global prevalence of mental health disorders has risen significantly since the beginning of the COVID-19 pandemic. The pandemic has additionally caused disruption to mental health services, leading to a shift from in-person to remote service delivery. Given its long-term impact, it has become critical to evaluate whether changes in health delivery during the pandemic have had an effect on prescribing patterns for commonly prescribed psychotropic drugs. This study aims to assess the impact of the COVID-19 pandemic on changes in psychotropic prescribing patterns in adults, as well as differences in prescribing in different healthcare delivery approaches across various geographical contexts.Design and eligibility requirementsSystematic review of cohort, interrupted time-series and cross-sectional studies examining prescribing trends for at least one commonly prescribed psychotropic drug during and after COVID-19 in accessing care remotely or face to face between 1 January 2020 and 17 June 2022.Data sourcesMEDLINE, EMBASE, CINAHL, HMIC and PsycINFO databases were searched in addition to citation chaining of relevant reviews.Extraction and analysisStudy screening, data extraction and quality assessment were completed by two independent reviewers. The PECO strategy was used to devise the systematic review and findings were synthesised narratively.Results16 studies were eligible for inclusion. Studies documenting changes in psychotropic prescribing trends provided very conflicting findings. There were no stark differences in prescribing outcomes between different healthcare delivery methods (ie, face-to-face consultations vs remote consultations). A noteworthy finding was that the prescribing rate of benzodiazepines was higher in women than men. No particular trends were observed for the prescription rates of hypnotics, antidepressants or antipsychotics.ConclusionsFindings support mixed trends in the prescription of psychotropic medications in a range of settings, hindering conclusive statements on COVID-19's impact on prescribing. In areas where remote consultations are in use, more comprehensive research is required to assess the safety of prescribing in these settings to inform public health policy and assess if the observed trends in our systematic review persist over time (given the increased consideration of remote and telehealth care in delivering services), particularly the safe and effective deployment of these services.

Project description:(1) Background and Objectives: The COVID-19 pandemic has considerably affected clinical systems, especially the emergency department (ED). A decreased number of pediatric patients and changes in disease patterns at the ED have been noted in recent research. This study investigates the real effect of the pandemic on the pediatric ED comprehensively by performing a systematic review of relevant published articles. (2) Materials and Methods: A systematic review was conducted based on a predesigned protocol. We searched PubMed and EMBASE databases for relevant articles published until 30 November 2021. Two independent reviewers extracted data by using a customized form, and any conflicts were resolved through discussion with another independent reviewer. The aggregated data were summarized and analyzed. (3) Results: A total of 25 articles discussing the impact of COVID-19 on pediatric emergencies were included after full-text evaluation. Geographic distribution analysis indicated that the majority of studies from the European continent were conducted in Italy (32%, 8/25), whereas the majority of the studies from North America were conducted in the United States (24%, 6/25). The majority of the studies included a study period of less than 6 months and mostly focused on the first half of 2020. All of the articles revealed a decline in the number of pediatric patients in the ED (100%, 25/25), and most articles mentioned a decline in infectious disease cases (56%, 14/25) and trauma cases (52%, 13/25). (4) Conclusions: The COVID-19 pandemic resulted in a decline in the number of pediatric patients in the ED, especially in the low-acuity patient group. Medical behavior changes, anti-epidemic policies, increased telemedicine use, and family financial hardship were possible factors. A decline in common pediatric infectious diseases and pediatric trauma cases was noted. Researchers should focus on potential child abuse and mental health problems during the pandemic.
