Studies were included provided they examined an association between COVID-19 cases and a crowding measure.<\/jats:p>\n <\/jats:sec>\n \n Data extraction and synthesis<\/jats:title>\n Data were extracted by one reviewer and cross-checked by another. Quantitative and qualitative data on prison cell standards and characteristics of studies examining an association between COVID-19 and prison crowding were collected.<\/jats:p>\n Findings were synthesised qualitatively.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n Seventeen reports and six studies met eligibility criteria. International and regional standards on cell spatial density were mostly qualitative, with two quantifiable international standards located (3.4 m\n 2<\/jats:sup>\n and 3.5 m\n 2<\/jats:sup>\n per person for multiple occupancy cells), and two quantifiable regional standards located (4 m\n 2<\/jats:sup>\n per person (Europe) and 5.75 m\n 2<\/jats:sup>\n or 4 m\n 2<\/jats:sup>\n per person (Australia and New Zealand)). Country-based standards varied substantially, ranging from 1.25 m\n 2<\/jats:sup>\n per person (Pakistan) to 10 m\n 2<\/jats:sup>\n per person (Netherlands). Consideration of airborne transmission of disease in prisons were mostly overlooked or absent to rationalise standards. There was consistent evidence that prison crowding measures were associated with COVID-19 transmission\/cases.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n Considering the physics of respiratory emissions, we recommend prison cell spatial density standards be updated to reflect graded levels of risk that consider other factors that combine to inform airborne transmission risk. Decarceration strategies should be considered and become vital if standards are not met.<\/jats:p>\n <\/jats:sec>","DOI":"10.1136\/bmjopen-2022-069952","type":"journal-article","created":{"date-parts":[[2023,4,4]],"date-time":"2023-04-04T13:55:26Z","timestamp":1680616526000},"page":"e069952","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":5,"title":["Rethinking standards on prison cell size in a (post)pandemic world: a scoping review"],"prefix":"10.1136","volume":"13","author":[{"given":"Simran","family":"Dahiya","sequence":"first","affiliation":[{"name":"School of Population Health, University of New South Wales, Sydney, New South Wales, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1947-8923","authenticated-orcid":false,"given":"Paul Leslie","family":"Simpson","sequence":"additional","affiliation":[{"name":"School of Population Health, University of New South Wales, Sydney, New South Wales, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tony","family":"Butler","sequence":"additional","affiliation":[{"name":"School of Population Health, University of New South Wales, Sydney, New South Wales, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2023,4,4]]},"reference":[{"key":"2025120523564007000_13.4.e069952.1","unstructured":"Howard J .
