[Characteristics of early arthritis units that may be associated with better referral efficiency: survey of SERAP units]. / Características de una unidad de artritis precoz que mejoran la eficiencia de la derivación: encuesta a las unidades SERAP.

OBJECTIVE: To identify characteristics of early arthritis units, that may be associated with better referral eficiency. METHODS: A national survey of the 36 early arthritis units (EAU) in Spanish Rheumatology Units in 2004 (SERAP project). Survey collected information about general practitioners (GP) educational program to improve knowledge and practical skills of early arthritis, networking and feed-back system and referral efficiency. EAU were classified in two groups according to 25 and 50% of inappropriate referral process, respectively. RESULTS: Thirty four of the 36 (94%) EAU, answered the survey. GP were trained in only 1 medical meeting in the primary care clinic, with one or more rheumatologists responsible of GP education. Fourteen of the 34 EAU (42.4%) regularly interacted with GP and only 20 (39.4%) contacted the GP who were responsible for the wrong referral process. Median lag time for referral to the Rheumatology out-patient clinic, was 73 days (15-365 days). The percentage of wrongly referred patients was between 0 and 80% (38% ± 21). Only 10 EAU (27.8%) referred patients appropriately according to the most strict criteria (25% of inappropriate referral) and 27 EAU (75%), according to 50% of inappropriate referral criteria. CONCLUSIONS: Only two aspects of the EAU implementation strategy were associated with better referral efficiency: 1) interaction with the GP responsible of the inappropriate referral process and 2) a lower median lag time for referral to the Rheumatology out-patient clinic.
