Management of spontaneous pneumothorax: an American College of Chest Physicians Delphi consensus statement.

OBJECTIVE Provide explicit expert-based consensus recommendations for the management of adults with primary and secondary spontaneous pneumothoraces in an emergency department and inpatient hospital setting. The use of opinion was made explicit by employing a structured questionnaire, appropriateness scores, and consensus scores with a Delphi technique. The guideline was designed to be relevant to physicians who make management decisions for the care of patients with pneumothorax. OPTIONS Decisions for observation, chest tube placement, surgical interventions, and radiographic imaging. OUTCOMES Effectiveness of pneumothorax resolution, duration of and patient tolerance of care, and pneumothorax recurrence. EVIDENCE Literature review from 1967 to January 1999 and Delphi questionnaire submitted in three iterations to a multidisciplinary physician panel. VALUES The guideline development group determined by consensus the relevant outcomes to be considered in developing the Delphi questionnaire. BENEFITS, HARMS, AND COSTS The type and magnitude of benefits, harms, and costs expected for patients from guideline implementation. RECOMMENDATIONS Management decisions vary between patients with primary or secondary pneumothoraces, with observation of small pneumothoraces being appropriate only for primary pneumothoraces. The level of consensus varies regarding the specific interventions indicated, but agreement exists for the general principles of care. VALIDATION Recommendations were peer reviewed by physician experts and were reviewed by the American College of Chest Physicians (ACCP) Health and Science Policy Committee. IMPLEMENTATION The guideline recommendations will be published in printed and electronic form with distribution of synopses for patients and health care providers. Contents of the guideline will be incorporated into continuing medical education programs. SPONSORS The ACCP.
