Bacterial pneumonia is the most frequent complication of influenza infection, and pneumococcal pneumonia is one of the most common causes of bacterial pneumonia. A vaccine to prevent pneumococcal pneumonia is available and persons with HIV/AIDS should receive one dose of pneumococcal polysaccharide vaccine (PPV), if they have not been vaccinated in the past. Various guidelines and national immunization programs recommend vaccination and revaccination every 5-10 years for persons living with HIV.

Formula: The number of patients/clients with at least one HIV primary care visit in the last 12 months who have had a pneumococcal vaccination in the past 10 years, divided by the total number of patients/clients with at least one HIV primary care visit in the last 12 months. Multiply by 100 to calculate percent.

Assess a random number of patient/client records monthly, or at the frequency established by your quality improvement effort. Identify your sample (patients/clients who had an HIV primary care visit in the previous 12 months).  For patients/clients in your sample, count the number of patients/clients with a documented pneumococcal vaccination in the past 10 years. Divide by the total number of patients with at least one HIV primary care visit in the past 12 months. Multiply by 100 to calculate percent. 

The National HIVQUAL Project’s Minimum Sample Table will help you determine the number of records to include in your sample. The Research Randomizer can generate a random number series to help you select which records to review.
