RESUMO

PURPOSE: Physicians-in-training often perform bedside thoracenteses in academic medical centers, and complications are more common among less experienced clinicians. Simulation-based mastery learning (SBML) is one potential solution to this problem. This study evaluated the effects of a randomized trial of thoracentesis SBML on patient complications: iatrogenic pneumothorax (IP), hemothorax, and reexpansion pulmonary edema (REPE). METHOD: The authors randomized internal medicine residents to undergo thoracentesis SBML at a tertiary care academic center from December 2012 to May 2016. They subsequently compared thoracentesis complications from procedures performed by SBML-trained residents, traditionally trained residents (no simulation training), and those referred to pulmonary medicine or interventional radiology (IR). RESULTS: During the study period, 917 thoracenteses were performed on 709 patients. IP occurred in 60 (6.5%) procedures, of which 7 (11.6%) were clinically meaningful. SBML-trained residents performed procedures with a trend toward lower combined clinically meaningful complications (IP, hemothorax, REPE) compared with traditionally trained residents (7.9% vs. 0%; P = .06). SBML-trained residents caused fewer clinically meaningful IPs compared with traditionally trained residents, pulmonary, and IR referrals (P = .02). Hemothorax occurred after 4 (0.4%) thoracenteses, and SBML-trained residents had a trend toward lower hemothorax (0) compared with other groups (P = .07). REPE occurred after 3 (0.3%) procedures, with no differences between groups. SBML-trained residents performed procedures with lower combined clinically meaningful complications compared with other groups (P = .008). CONCLUSIONS: Residents randomized to an SBML intervention performed thoracenteses with low rates of clinically meaningful complications. Rigorous education represents a successful quality improvement strategy.

RESUMO

Internal medicine (IM) residents and hospitalist physicians commonly perform thoracenteses. National data show that thoracenteses are also frequently referred to other services such as interventional radiology (IR), increasing healthcare costs. Simulation-based mastery learning (SBML) is an effective method to boost physicians' procedural skills and self-confidence. This study aimed to (1) assess the effect of SBML on IM residents' simulated thoracentesis skills and (2) compare thoracentesis referral patterns, self-confidence, and reasons for referral between traditionally trained residents (non-SBML-trained), SBML-trained residents, and hospitalist physicians. A random sample of 112 IM residents at an academic medical center completed thoracentesis SBML from December 2012 to May 2015. We surveyed physicians caring for hospitalized patients with thoracenteses during the same time period and compared referral patterns, self-confidence, and reasons for referral. SBML-trained resident thoracentesis skills improved from a median of 57.6% (interquartile range [IQR] 43.3-76.9) at pretest to 96.2% (IQR 96.2-100.0) at post-test (P < 0.001). Surveys demonstrated that traditionally trained residents were more likely to refer to IR and cited lower confidence as reasons. SBML-trained residents were more likely to perform bedside thoracenteses. Hospitalist physicians were most likely to refer to pulmonary medicine and cited lack of time to perform the procedure as the main reason. SBML-trained residents were most confident about their thoracentesis skills, despite hospitalist physicians having more experience. This study identifies confidence and time as reasons physicians refer thoracenteses rather than perform them at the bedside. Thoracentesis SBML boosts skills and promotes bedside procedures that are safe and less expensive than referrals. Journal of Hospital Medicine 2016;11:792-795. © 2016 Society of Hospital Medicine.

RESUMO

BACKGROUND: Despite a lack of evidence in the literature, several assumptions exist about the safety of thoracentesis in clinical guidelines and practice patterns. We aimed to evaluate specific demographic and clinical factors that have been commonly associated with complications such as iatrogenic pneumothorax, re-expansion pulmonary oedema (REPE) and bleeding. METHODS: We performed a cohort study of inpatients who underwent thoracenteses at Cedars-Sinai Medical Center (CSMC) from August 2001 to October 2013. Data were collected prospectively including information on volume of fluid removed, procedure side, whether the patient was on positive pressure ventilation, number of needle passes and supine positioning. Iatrogenic pneumothorax, REPE and bleeding were tracked for 24 h after the procedure or until a clinical question was reconciled. Demographic and clinical characteristics were obtained through query of electronic medical records. RESULTS: CSMC performed 9320 inpatient thoracenteses on 4618 patients during the study period. There were 57 (0.61%) iatrogenic pneumothoraces, 10 (0.01%) incidents of REPE and 17 (0.18%) bleeding episodes. Iatrogenic pneumothorax was significantly associated with removal of >1500 mL fluid (p<0.0001), unilateral procedures (p=0.001) and more than one needle pass through the skin (p=0.001). For every 1 mL of fluid removed there was a 0.18% increased risk of REPE (95% CI 0.09% to 0.26%). There were no significant associations between bleeding and demographic or clinical variables including International Normalised Ratio, partial thromboplastin time and platelet counts. CONCLUSIONS: Our series of thoracenteses had a very low complication rate. Current clinical guidelines and practice patterns may not reflect evidence-based best practices.
