Evaluation of community-based CT abdomen for acute abdominal pain during COVID-19.

AIM: The purpose of this study was to determine the utility of community-based imaging to reduce use of inpatient surgical resources and enforce social distancing at the outset of the COVID-19 pandemic. METHOD: A prospective evaluation of community-based CT for patients presenting to Christchurch general practitioners with acute abdominal pain from April to November 2020. Eligible patients were discussed with the on-call general surgical team, and then referred for CT abdomen rather than hospital assessment. The positivity rate of CT scans, the 30-day all-cause hospital admission rate, and the proportion of patients where community scanning altered management setting and the number of incidental findings, were all assessed. RESULTS: Of 131 included patients, 67 (51%) patients had a positive CT scan. Thirty-nine (30%) patients were admitted to hospital within 30 days, 34 (87%) of whom had a positive CT scan and were admitted under a surgical specialty. Ninety-two (70%) patients did not require hospital admission for their acute abdominal pain, thirty-three (35%) of whom had a positive CT scan. There were three deaths within 30 days of the community CT, and the setting of the community CT did not contribute to the death of any of the cases. Forty patients (30%) had incidental findings on CT, 10 (25%) of which were significant and were referred for further investigation. CONCLUSION: Community based abdominal CT scanning is a feasible option in the management of acute abdominal pain. While trialed in response to the initial nationwide COVID-19 lockdown in New Zealand, there may be utility for acute community-based CT scanning in regular practice.

Resilience and Equity in a Time of Crises: Investing in Public Urban Greenspace Is Now More Essential Than Ever in the US and Beyond.

The intersecting negative effects of structural racism, COVID-19, climate change, and chronic diseases disproportionately affect racial and ethnic minorities in the US and around the world. Urban populations of color are concentrated in historically redlined, segregated, disinvested, and marginalized neighborhoods with inadequate quality housing and limited access to resources, including quality greenspaces designed to support natural ecosystems and healthy outdoor activities while mitigating urban environmental challenges such as air pollution, heat island effects, combined sewer overflows and poor water quality. Disinvested urban environments thus contribute to health inequity via physical and social environmental exposures, resulting in disparities across numerous health outcomes, including COVID-19 and chronic diseases such as cancer and cardiovascular diseases (CVD). In this paper, we build off an existing conceptual framework and propose another conceptual framework for the role of greenspace in contributing to resilience and health equity in the US and beyond. We argue that strategic investments in public greenspaces in urban neighborhoods impacted by long term economic disinvestment are critically needed to adapt and build resilience in communities of color, with urgency due to immediate health threats of climate change, COVID-19, and endemic disparities in chronic diseases. We suggest that equity-focused investments in public urban greenspaces are needed to reduce social inequalities, expand economic opportunities with diversity in workforce initiatives, build resilient urban ecosystems, and improve health equity. We recommend key strategies and considerations to guide this investment, drawing upon a robust compilation of scientific literature along with decades of community-based work, using strategic partnerships from multiple efforts in Milwaukee Wisconsin as examples of success.
