When a healthcare organization identifies a problem that is impacting its performance, such as post-surgical respiratory failure rates negatively impacting reimbursement projections, the first step is typically to gather more information about the issue123.

In this case, the best way to do that would be to obtain a list of the patients identified by this code and conduct a retrospective review (Option D)123. This would allow the organization to look back at the medical records of these patients to understand more about their cases, including potential risk factors, the course of their treatment, and the outcomes they experienced123.

This information can then be used to identify patterns or trends that might be contributing to the high rates of post-surgical respiratory failure123. For example, the review might reveal that certain surgical procedures, patient characteristics, or care practices are associated with a higher risk of respiratory failure123.

Once this information has been gathered and analyzed, the organization can then move on to the next steps in the quality improvement process, such as identifying potential interventions, implementing changes, and monitoring their impact123.
