A risk of percutaneous transthoracic needle biopsy (PTNB) is hemoptysis, which can range from mild to life-threatening. The reported occurrence of hemoptysis is 1.7% to 14.5%, and the demographic, patient, and procedure characteristics have not been extensively described. The purpose of this study was to assess the associations of demographic, patient, and procedure characteristics with the severity of hemoptysis. A single institution, single group, retrospective, electronic medical record (EMR) review was performed on all hemoptysis events occurring between 2008 and 2018. Demographic, clinical, and procedure variables were extracted from EMRs. Outcome of hemoptysis events was graded using Common Terminology Criteria for Adverse Events (CTCAE). Mild-moderate and severe hemoptysis were defined as CTCAE classifications of 1-2 and 3-5, respectively. Associations were generated using logistic regressions and Likelihood Ratio Chi-Square tests. In 10 years, 14,665 PTNB resulted in 231 hemoptysis events occurring in 229 patients; 12.7% (n = 29) of those were severe. The strongest and statistically significant variables associated with an increased likelihood of a severe event, if an event occurred, were cigarette pack years (OR = 1.02, 95% C.I. = 1.01-1.04, p =.020); history of chronic obstructive pulmonary disease (COPD) (OR = 3.68, 95% C.I. = 1.53-8.82, p =.003); core biopsy technique (OR = 8.13, 95% CI = 1.07, 61.40, p =.042), and larger diameter needle (20 g vs. 18 g: OR = 2.60, 95% CI 1.09, 6.17, p =.031). PTNB-associated hemoptysis was an uncommon event that was rarely life-threatening. The extent of the patient's smoking history, the diagnosis of COPD, and core biopsy technique were associated with an increased likelihood of severe hemoptysis. • The overall occurrence of hemoptysis following percutaneous transthoracic needle biopsy (PTNB) was 1.6%. • Severe hemoptysis events occurred in 0.2% of all biopsies performed over a 10-year period. • The strongest and statistically significant variables associated with an increased likelihood of a severe event, if an event occurred, were cigarette pack years (OR = 1.02, 95% C.I. = 1.01-1.04, p =.020); history of chronic obstructive pulmonary disease (COPD) (OR = 3.68, 95% C.I. = 1.53-8.82, p =.003); core biopsy technique (OR = 8.13, 95% CI = 1.07, 61.40, p =.042), and larger diameter needle (20 g vs. 18 g: OR = 2.60 (1.09, 6.17), p =.031).
