The I COUGH Multidisciplinary Perioperative Pulmonary Care Program: One Decade of Experience.

Background: Surgical quality improvement programs can provide meaningful benefits for patient outcomes, but sustainability of initial success is rarely described. In response to data that revealed a greater than predicted likelihood of postoperative pulmonary complications in one hospital, the study team designed a standardized program to improve care. This study offers a long-term perspective of the effort, including special challenges and lessons learned about sustaining success.

Methods: A before-after study was conducted at an academic safety-net hospital. A multidisciplinary team developed tactics to reduce pulmonary complications, designated by the acronym I COUGH: Incentive spirometry, Coughing/deep breathing, Oral care, Understanding (education), Getting out of bed, and Head of bed elevation. Clinical practices were audited and compared to actual and risk-adjusted pulmonary outcomes.

Results: Improvements in compliance with the I COUGH elements were initially promising, but baseline behaviors eventually returned. Adverse outcomes have inversely correlated with process adherence in "sawtooth" patterns. Rejuvenation efforts have successively extended beyond the literal principles of the acronym to foster broader institutional commitment to perioperative pulmonary care, restoring favorable trends in both process and outcomes. A more comprehensive I COUGH program now extends beyond the acronym, applying numerous concepts to support the original program.

Conclusion: I COUGH, a standardized perioperative pulmonary care program, initially improved performance and reduced pulmonary complications. However, loss of early program momentum corresponded with a return to baseline outcomes. Fortunately, an overall favorable trend has resulted from a coordinated rededication to I COUGH that requires steadfast commitment and creative responses to numerous cultural barriers.
