Comparisons of immunization records between a community pharmacy, a regional registry, and a health system.

Objectives: To compare the completeness of immunization records for 6 vaccines between a community pharmacy database, a regional immunization information system (IIS), and a health system's electronic health record (EHR).

Methods: In a community pharmacy immunization program, 2 pharmacists and a community pharmacy resident performed a needs assessment for 6 vaccines (tetanus-diphtheria-acellular pertussis vaccine for adults or diphtheria-tetanus-acellular pertussis vaccine for children and adolescents, zoster vaccine live, 13-valent pneumococcal conjugate vaccine, 23-valent pneumococcal polysaccharide vaccine, hepatitis B vaccine series, and human papillomavirus vaccine) for more than 2400 patients from August 2016 to March 2017. This was a retrospective study to review immunization records for 243 patients.
