ABSTRACT
BACKGROUND: Asthma and chronic obstructive pulmonary disease (COPD) outcomes vary by sex. We investigated whether males and females with asthma or COPD are managed differently in-hospital when admitted for an exacerbation.
METHODS: Data from the National Asthma and COPD Audit Programme were used to determine three cohorts of people hospitalised for an exacerbation: (1) adults with asthma, (2) children and young people (CYP) with asthma, and (3) adults with COPD. Outcomes included the following in-hospital interventional measures: spirometry recording, respiratory specialist review, respiratory medication administration and discharge bundle recording. Linked hospital data were used to determine 30-day and 90-day readmissions and Office for National Statistics data for 90-day mortality. Random effects logistic regression was used to investigate the association between sex and in-hospital outcomes, readmission and mortality.
RESULTS: 16 370 adults with asthma, 7156 CYP with asthma and 28 354 adults with COPD were included. Female adults with asthma had higher odds of being seen by a respiratory specialist (aOR 0.1.13, 1.02-1.26) and higher odds of readmission within 30 and 90 days (aOR 1.22, 1.10-1.37, aOR 1.34, 1.23-1.46) compared with males. Female adults with COPD had higher odds of being seen by a respiratory specialist, (aOR 1.10,1.02-1.19), being administered non-invasive ventilation (aOR 1.18, 1.09-1.29), and receiving a discharge bundle (aOR 1.07, 1.00-1.14), and lower odds of readmission within 90 days (aOR 0.95, 0.90-1.01), or mortality within 90 days (aOR 0.88, 0.81-0.96). Lastly, female CYP had higher odds of steroids administered within 1 hour (aOR 1.13, 1.00-1.28) and higher 30-day and 90-day readmission compared with males (aOR 1.21, 1.00-1.44 and 1.17, 1.03-1.34).
INTERPRETATION: Sex differences in in-hospital care exist in adults COPD, which may impact readmissions and mortality; however, little to no sex differences in in-hospital care were seen in people with asthma yet females were more likely to be readmitted to hospital.
