HOSPITAL TEACHING STATUS ON THE INCIDENCE OF POSTPROCEDURAL PNEUMOTHORAX: A RETROSPECTIVE NATIONAL IN-PATIENT SAMPLE STUDY

TOPIC: Procedures TYPE: Original Investigations PURPOSE: Postprocedural pneumothorax (iatrogenic) is a patient safety indicator resulting from invasive procedures such as insertion of subclavian central line, pacemaker/ implantable cardiac defibrillator (ICD) placement, transbronchial lung biopsy and transthoracic pulmonary biopsy. This study examines if any these have higher predisposition to iatrogenic in teaching hospitals compared non-teaching hospital. METHODS: Cohort patients aged 18 or older who had percutaneous biopsy, trans-bronchial line pacemaker/ICD placement were identified the National Inpatient Sample (NIS) database years 2016 2017 using ICD 10-procedure codes. Diagnosis was 10 – diagnosis code. Incidence post-procedural estimated for overall hospital encounter each procedures. The incidence rate between group (TH) (NTH) chi-square statistical test. Odds ratio (OR) comparing both with logistic regression. RESULTS: Iatrogenic 2,951 13,575 (21.7%) 21.6% TH vs 22.1% NTH ( OR 0.96, 95% CI 0.88 1.05, p = 0.41). Among occurred 890 out 26,793 (3.3%) 3.6% 2.6% 1.37, 1.17 1.59, <0.001). Across 568,677 insertions, also (0.43% 0.34% NTH, 1.26, 1.15 1.39, Pacemaker/ICD 83,033 resulted 1.17% 1.44% (OR 0.81, 0.71 0.92, 0.02). Overall, total 18,703 cases 14 million (unweighted) admissions 144 events per 100,000 encounters 103 NTH. CONCLUSIONS: Our showed significantly among undergoing insertion. And lower placement. not different two groups. more prevalent hospitals. Randomized controlled studies are needed identify etiology our findings.
