An alternative approach to assess surgical volume is from household surveys, which might be more suitable for low\u2010income settings. The aim of this study was to describe the annual surgical volume in Sierra Leone through a population\u2010based approach and compare this with health facility data.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This study is part of the PRESSCO 2020 (PREvalence Study on Surgical COnditions) study, a cross\u2010sectional countrywide descriptive study based on a randomly selected national representative sample. Data on surgeries performed annually, including type and location, were collected through interviews and compared with facility\u2010based data.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>In total, 10,001 household members were included from 1854 households, who reported 152 major surgical procedures the year preceding the interview. Amounting an annual nation\u2010wide surgical volume of 1520 (95% CI 1300\u20131780) per 100,000 population. The most common procedures were hernia repairs (30.9%), caesarean sections (23.7%), and appendicectomies (13.8%). The population\u2010based data collection identified 4.1 times more procedures compared with 372 procedures in facility\u2010based study from the same year.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The substantial difference between population\u2010 and facility\u2010based data reveals a likely underreporting in facilities and possible overreporting in the household survey. Interpretation of facility\u2010based surgical volume data should be carried out with caution and rigorous description of methodology is essential for proper interpretation. Independent of the method of data collection, the surgical volume in Sierra Leone is far below the recommended global benchmark.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Trial Registration<\/jats:title>\n                    <jats:p>ISRCTN registry under no 12353489.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1002\/wjs.70050","type":"journal-article","created":{"date-parts":[[2025,8,16]],"date-time":"2025-08-16T03:10:32Z","timestamp":1755313832000},"page":"2523-2530","source":"Crossref","is-referenced-by-count":1,"title":["Surgical Volume in Sierra Leone: A Comparison Between Population and Facility\u2010Based Data Collection"],"prefix":"10.1002","volume":"49","author":[{"given":"Janine P.
