Feldman CH, Speyer C, Ashby R, et al. - Researchers describe the systemic lupus erythematosus (SLE)-specific adverse consequences that could be averted or their complications be reduced by timely effective ambulatory care. They picked initial SLE-specific potentially preventable conditions by using a modified Delphi process commencing with a literature review and key informant interviews. From eight subspecialties, sixteen nationally-recognized US-based experts were gathered to form a panel. Two survey rounds were conducted. Four classes of 25 SLE-specific conditions reaching consensus as potentially preventable and significant on a population level were defined: vaccine-preventable illnesses (6 conditions), medication-associated complications (8), reproductive health-associated complications (6) and SLE-associated complications (5). In this study, a consensus was reached on a distinct set of adverse results relevant to SLE patients that may be avoidable if patients were administered high quality ambulatory care. For learning the best allocation of resources as well as for improving quality to decrease avoidable results and differences among those at highest risk, these results may be studied at the health system level.
