Characteristics of long-term care facilities associated with standing order programs to deliver influenza and pneumococcal vaccinations to residents in 13 states

Although LTCFs with certain characteristics used SOPs more often, overall few facilities (<10%) used SOPs to improve vaccination rates. SOP use varied by state indicating that state policies or other factors may promote or inhibit SOP use. More studies are needed to examine the causes of state-level variations in vaccination interventions and their relationships to health outcomes of residents in LTCFs. The federal government's resources to promote SOPs should focus on all LTCFs, but with a particular focus on those that are less likely to be using SOPs and that represent a large proportion of homes nationally (i.e., for-profit and chain facilities).
