Intraoperative and postprocedural respiratory disorders admissions profile: An ecological longitudinal study in England and Wales

Postoperative respiratory complications are widespread and associated with several healthcare systems and financial burdens. Studying admissions due to these complications may aid in developing preventive measures and approaches. However, such studies are lacking in England and Wales. Therefore, this study aims to study the admissions related to intraoperative and postprocedural respiratory disorders (IPPRDs). This was an ecological study using publicly available data extracted from the Hospital Episode Statistics database in England. The diagnostic code (J95) was used to identify all hospital admission related to different types of IPPRDs. Time trends were assessed using Joinpoint regression, reporting annual percent change (APC) and average annual percent change (AAPC) with 95% confidence intervals. Between 1999 and 2020, the overall admission rate for IPPRDs showed a modest increased between 1999 and 2014 (APC 2.2%, P < .001), followed by a decline between 2014 and 2019 (APC-2.9%, P = .02). The most common cause of admissions was "tracheostomy malfunction." However, the highest increase in admissions rate was for "Mendelson syndrome." The hospital admissions rates for most disorders were more common among those aged ≥ 60 years, and males showed higher admission rates compared to females.. However, the relative increase was greater among females. The study demonstrates a slight increase in hospital admissions rates for IPPRDs from 1999 to 2020, possibly due to diagnosis advancement, updating coding, and patient factors. Intraoperative and postprocedural respiratory disorders admissions trends were varied by age and gender, suggesting a need for preventive measures that consider age and gender factors. More research is required to investigate other possible factors resulting in these trends.
