A Composite Indicator to Assess the Quality of Care in the Management of Patients With Rheumatoid Arthritis in Outpatient Rheumatology Clinics

Abstract Objective The current guidelines in the treatment of rheumatoid arthritis (RA) include the early diagnosis and early use of disease modifying drugs to achieve remission or low disease activity level, known as “Treat to Target” (T2T). The objective of this study is to develop a composite indicator (CI) to evaluate the quality of care in the management of patients with RA, according to the T2T strategy and other general recommendations concerning the management of these patients. Material and method The phases of the construction of the CI were: (1) selection of quality criteria through expert judgement; (2) prioritisation of the criteria, according to relevance and feasibility, applying the Delphi methodology (two rounds) involving 20 experts; (3) design of quality indicators; and (4) calculation of the weighted CI, using the mean value in relevance and feasibility granted by the experts. The source of information for the calculation of the CI are the medical records of patients with RA. Results Twelve criteria out of 37 required a second Delphi round. Thirty-one criteria were prioritised. These criteria presented a median in relevance and feasibility greater than or equal to 7.5, with an interquartile range of less than 3.5, and a level of agreement (score greater than or equal to 8) greater than or equal to 80%. Conclusions The constructed CI allows us to evaluate the quality of care of patients with RA following the T2T strategy in the rheumatology units of Spanish hospitals, offering a valid and easily interpretable summary measure.
