Abstract

ObjectivesVenous thromboembolism (VTE) is a major cause of morbidity and mortality globally, with hospital-associated thrombosis (HAT) accounting for at least half of VTE. We set out to understand more about deaths from HAT in England, to focus improvement efforts where they are needed most.DesignA retrospective cohort combining death certification and hospital activity data to identify people with an inpatient or day case hospitalisation where no VTE diagnosis was recorded, and who died from VTE in a hospital or within 90 days of discharge, between April 2017 and March 2020.SettingAll deaths occurring in England and all National Health Service-funded hospital care in England.ParticipantsAfter 0.1% of cases were excluded due to duplicate but conflicting records, a cohort of 13 995 deaths remained; 54% were women, and 26% were aged under 70 years.Outcome measuresAnalysis of age, gender, primary diagnosis, type of admission, specialties and (for day cases) procedure types were preplanned.ResultsOnly 5% of these deaths followed planned inpatient admissions. Day case admissions preceded 7% of VTE deaths. Emergency inpatient admissions, medical specialties and infection-related primary diagnoses predominated in people who died from VTE after hospitalisation where no VTE diagnosis was recorded. Most deaths occurred in a hospital or within 30 days of discharge.ConclusionsInternational efforts to reduce HAT historically focused on planned inpatient admissions. Further initiatives and research to prevent deaths from VTE after hospitalisation should focus on the emergency care pathway where most deaths occurred, with people undergoing day case procedures an important additional focus.
