Every 3\u20134\u2009years, the Royal College of Anaesthetists, as part of its National Audit Projects (NAP), performs a snapshot activity survey in all UK hospitals delivering anaesthesia, collecting patient\u2010level encounter data from all cases under the care of an anaesthetist. During November 2021, as part of NAP7, anaesthetists recorded details of all cases undertaken over 4\u2009days at their site through an online survey capturing anonymous patient characteristics and anaesthetic details. Of 416 hospital sites invited to participate, 352 (85%) completed the activity survey. From these, 24,177 reports were returned, of which 24,172 (99%) were included in the final dataset. The work patterns by day of the week, time of day and surgical specialty were similar to previous NAP activity surveys. However, in non\u2010obstetric patients, between NAP5 (2013) and NAP7 (2021) activity surveys, the estimated median age of patients increased by 2.3\u2009years from median (IQR) of 50.5 (28.4\u201369.1) to 52.8 (32.1\u201369.2) years. The median (IQR) BMI increased from 24.9 (21.5\u201329.5) to 26.7 (22.3\u201331.7) kg.m\n                    <jats:sup>\u20132<\/jats:sup>\n                    . The proportion of patients who scored as ASA physical status 1 decreased from 37% in NAP5 to 24% in NAP7. The use of total intravenous anaesthesia increased from 8% of general anaesthesia cases to 26% between NAP5 and NAP7. Some changes may reflect the impact of the COVID\u201019 pandemic on the anaesthetic population, though patients with confirmed COVID\u201019 accounted for only 149 (1%) cases. These data show a rising burden of age, obesity and comorbidity in patients requiring anaesthesia care, likely to impact UK peri\u2010operative services significantly.\n                  <\/jats:p>","DOI":"10.1111\/anae.15989","type":"journal-article","created":{"date-parts":[[2023,3,1]],"date-time":"2023-03-01T17:01:06Z","timestamp":1677690066000},"page":"701-711","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":122,"title":["Patient characteristics, anaesthetic workload and techniques in the\n                    <scp>UK<\/scp>\n                    : an analysis from the 7th National Audit Project (\n                    <scp>NAP7<\/scp>\n                    ) activity survey"],"prefix":"10.1111","volume":"78","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9488-4086","authenticated-orcid":false,"given":"A.
