Studies that reported solely on high-risk women (eg, those with antenatal or intrapartum complications) were excluded, but mixed population samples were included (eg, low-risk and high-risk women).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>MEDLINE, Embase, Web of Science, and CINAHL were searched for published studies on December 20, 2019, and searches were updated on May 11, 2021. Critical appraisal was undertaken by 2 independent reviewers using standardized critical appraisal instruments from JBI. Quantitative data were extracted from included studies independently by at least 2 reviewers using a study-specific data extraction form. Quantitative data were pooled, where possible. Identified studies were used to obtain the summary estimate (proportion) for each time point. Maternal mortality was calculated as the maternal deaths during a given period over the total number of maternal deaths known during the postpartum period. For cause-specific analysis, number of deaths due to a specific cause was the numerator, while the total number of women who died due to the same cause in that period was the denominator. Random effects models were run to pool incidence proportion for relative risk of overall maternal deaths. Subgroup analysis was conducted according to country income classification and by date (ie, data collection before or after 2010). Where statistical pooling was not possible, the findings were reported narratively.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>A total of 32 studies reported on maternal outcomes from 17 reports, all reporting on mixed populations. Most maternal deaths occurred on the first day (48.9%), with 24.5% of deaths occurring between days 2 and 7, and 24.9% occurring between days 8 and 42. Maternal mortality due to postpartum hemorrhage and embolism occurred predominantly on the first day (79.1% and 58.2%, respectively). Most deaths due to postpartum eclampsia and hypertensive disorders occurred within the first week (44.3% on day 1 and 37.1% on days 2\u20137). Most deaths due to infection occurred between days 8 and 42 (61.3%). Due to heterogeneity, maternal morbidity data are described narratively, with morbidity predominantly occurring within the first 2 weeks. The mean critical appraisal score across all included studies was 85.9% (standard deviation\u200a=\u200a13.6%).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Women experience mortality throughout the entire postpartum period, with the highest mortality rate on the first day. Access to high-quality care during the postpartum period, including enhanced frequency and quality of postpartum assessments during the first 42\u200adays after birth, is essential to improving maternal outcomes and to continue reducing maternal mortality and morbidity worldwide.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Systematic review registration number:<\/jats:title>\n                    <jats:p>PROSPERO CRD42020187341<\/jats:p>\n                  <\/jats:sec>","DOI":"10.11124\/jbies-20-00578","type":"journal-article","created":{"date-parts":[[2022,3,13]],"date-time":"2022-03-13T21:00:30Z","timestamp":1647205230000},"page":"2119-2194","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":106,"title":["Timing of maternal mortality and severe morbidity during the postpartum period: a systematic review"],"prefix":"10.11124","volume":"20","author":[{"given":"Justine","family":"Dol","sequence":"first","affiliation":[{"name":"Faculty of Health, Dalhousie University, Halifax, NS, Canada"},{"name":"Aligning Health Needs and Evidence for Transformative Change (AH_NET-C): A JBI Centre of Excellence, Dalhousie University, Halifax, NS, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Brianna","family":"Hughes","sequence":"additional","affiliation":[{"name":"Aligning Health Needs and Evidence for Transformative Change (AH_NET-C): A JBI Centre of Excellence, Dalhousie University, Halifax, NS, Canada"},{"name":"School of Nursing, Dalhousie University, Halifax, NS, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mercedes","family":"Bonet","sequence":"additional","affiliation":[{"name":"UNDP\/UNFPA\/ UNICEF\/WHO\/World Bank Special Programme of Research, Development and Research Training in Human Reproduction (HRP), Department of Sexual and Reproductive Health and Research, World Health Organization, Geneva, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rachel","family":"Dorey","sequence":"additional","affiliation":[{"name":"School of Nursing, Dalhousie University, Halifax, NS, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jon","family":"Dorling","sequence":"additional","affiliation":[{"name":"Division of Neonatal Perinatal Medicine, Department of Pediatrics, Faculty of Medicine, Dalhousie University and IWK Health Centre, Halifax, NS, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Amy","family":"Grant","sequence":"additional","affiliation":[{"name":"Maritime SPOR Support Unit, Halifax, NS, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Etienne V.","family":"Langlois","sequence":"additional","affiliation":[{"name":"Partnership for Maternal, Newborn and Child Health, World Health Organization, Geneva, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joelle","family":"Monaghan","sequence":"additional","affiliation":[{"name":"Centre for Research in Family Health, IWK Health Centre, Halifax, NS, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rachel","family":"Ollivier","sequence":"additional","affiliation":[{"name":"School of Nursing, Dalhousie University, Halifax, NS, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Robin","family":"Parker","sequence":"additional","affiliation":[{"name":"W.K.
