Evaluation of knowledge, barriers, and attitudes in the management of type 2 diabetes in elderly patients: A Delphi study on primary and hospital care.

OBJECTIVES: This work aims to explore attitudes regarding the management of elderly or frail patients with type 2 diabetes mellitus in the routine clinical practice of a multidisciplinary group of physicians in Spain. METHODS: A mixed survey was used that included both Delphi and opinion, attitude, and behaviour (OAB) questions. Perceptions in primary care (n = 211) and hospital care (n = 80) were compared. RESULTS: Consensus was obtained on all statements. Eighty-seven percent of participants considered that severe psychiatric disorders conditioned antidiabetic treatment and 72% that a psychocognitive assessment is as relevant as the assessment of other comorbidities. Hospital care physicians more frequently considered that comorbidity affects self-care (95.0% vs. 82.9%), that a lack of de-intensification is a form of therapeutic inertia (88.8% vs. 76.3%), that classifying older adults as frail is fundamental to choosing targets (96.3% vs. 87.7%), that de-intensification of antidiabetic treatment and control of cardiovascular risk factors should be considered in those over 80 years of age (90.0% vs. 78.7%), and that type 2 diabetes mellitus predisposes patients to sarcopenia (86.3% vs. 71.6%). The usefulness of clinical guidelines was more highly valued among primary care participants (79.1% vs. 72.5%). CONCLUSIONS: There is room for improvement on several aspects of managing elderly or frail patients with type 2 diabetes mellitus, including inertia in treatment de-intensification, conducting a psychocognitive assessment, or the identification of frailty and sarcopenia.

Shifting from glucose diagnostic criteria to the new HbA(1c) criteria would have a profound impact on prevalence of diabetes among a high-risk Spanish population.

AIM: To investigate changes in the prevalence of diabetes and pre-diabetes by shifting from 2-h plasma glucose and/or fasting plasma glucose diagnostic criteria to the proposed new HbA(1c) -based criteria when applied to a Mediterranean population detected to have a high risk of Type 2 diabetes. METHODS: Individuals without diabetes aged 45-75 years (n = 2287) were screened using the Finnish Diabetes Risk Score questionnaire, a 2-h oral glucose tolerance test plus HbA(1c) test. Prevalence and degree of diagnostic overlap between three sets of criteria (2-h plasma glucose, fasting plasma glucose and HbA(1c) ) and three diagnostic categories (normal, pre-diabetes and diabetes) were calculated. RESULTS: Defining diabetes by a single HbA(1c) measurement resulted in a dramatic decrease in prevalence (1.3%), particularly in comparison with diabetes defined by 2-h plasma glucose (8.6%), but was also significant with regard to fasting plasma glucose (2.8%). A total of 201 screened subjects (8.8%) were classified as having diabetes and 1023 (44.7%) as having pre-diabetes based on at least one of these criteria; among these, the presence of all three criteria simultaneously classified only 21 and 110 individuals respectively, about ten percent of each group. The single overlap index between subjects diagnosed as having diabetes by 2-h plasma glucose/fasting plasma glucose vs. HbA(1c) was 13.9/28%. Similarly, the single overlap index regarding pre-diabetes was 19.2/27.1%. CONCLUSIONS: A shift from the glucose-based diagnosis to the HbA(1c) -based diagnosis for diabetes will reduce diabetes prevalence with a low overall or single degree of overlap between diagnostic categories in this high-risk Spanish population.
