Failure of access to structured diabetes care is associated with adverse outcome. There is no known validated data tool to identify access failure and thus we have developed a Failed Access Score (FAS) and have examined its associations.The FAS is part of the WICKED project (Wolverhampton Interface Care, Knowledge Empowered Diabetes), and consists of three key care processes in diabetes: namely HbA1c, urinary albumin:creatinine ratio and retinal screening. A retrospective case control study in a single GP practice was undertaken on all the patients (n=478) failing two or more parameters over 15 months. They were compared to those with no access failure matched for age, gender, ethnicity and type of diabetes.Among the 51 cases with a FAS ≥2, two or three process measures were absent in 84% and 16% respectively. Excluding service failure, this was due to non-attendance in 35% but otherwise associated with other clinical constraints in 41% (mental health, house bound, palliative care, multi-morbidity) and their deprivation index was significantly higher (p<0.01). Extrapolating to the whole health economy (n=16 644), 2362 (14%) would have a FAS of ≥2 of whom 968 (6%) would have failed access in association with these constraints.In conclusion, it is possible to identify people who are failing access to structured diabetes care using readily available data calculated as the FAS score. Failed access is not usually due to patient default or disengagement but rather, in almost 65%, either due to significant clinical disadvantage or pure failure of service. The objective of this study is to determine whether this score identifies access failure that can be attributed to identifiable factors among individuals with diabetes.
Methods
The Failed Access ScoreThe FAS consists of three key care processes in diabetes: namely HbA1c, urinary albumin:creatinine ratio (ACR) and retinal screening. This maps to all domains of diabetes care processes in the form of: a blood test (HbA1c) -meaning that all blood tests could have been done; a urine test (ACR) -meaning that the patient attended a clinical appointment so that all clinical measures could have been completed; and a retinal screening testconfirming that the patients are in receipt of communication and able to engage in self-care. Each of these parameters is universally captured in the central database wherever undertaken, whereas others may not be (e.g. weight, blood pressure etc). Completion of all three processes is indicative that the patient has access to the service and engaged to the extent that enough opportunity existed for the health services to complete all nine key care processes in diabetes. Failure of any one parameter over the preceding 15 months was scored 1. A score of zero meant that all three parameters were completed, while a score of 3 meant maximal failure of access such that none of the three parameters were completed and there was no access to the service.
