The Joint Commission standards are no longer in effect and the topic of pneumonia is being rewritten and should be available in 2019. The Joint Commission and the Centers for Medicare & Medicaid Services partnered in 2004 to create core measures for disease management for community-acquired pneumonia. The measures create consistent evidence-based practice in institutions caring for CAP patients. The Centers for Medicare & Medicaid Services measures hospitals' adherence to the core measures and publishes the results for key stakeholders, such as patients and insurers, to compare. The CAP core measures provide a common set of measures for hospitals to use. The intent was to construct a system that would be easier and less costly for hospitals to follow. Core measures are integral to improving the care of inpatients and focus on the results of that care. The CAP treatment guidelines were developed with the support of the American Thoracic Society, the Infectious Disease Society of America, and the Centers for Disease Control and Prevention.
