Background: Routine clinical coding of clinical outcomes in outpatient consultations still lags behind the coding of episodes of inpatient care. Systematized Nomenclature of Medicine Clinical Terms (SNOMED CT) offers an opportunity for standardised coding of key clinical information. Identifying the most commonly required SNOMED terms and grouping these into a reference set will aid future adoption in routine clinical care. Objective: To create a common endocrinology reference set to standardise the coding for outcomes of outpatient endocrine consultations, using a semi‐automated extraction of information from existing clinical correspondence. Methods: Retrospective review of data from an adult tertiary outpatient endocrine clinic between 2018 and 2019. A total of 1870 patients from postcodes within two regional areas of NHS Grampian (Aberdeen City and Aberdeenshire) attended the clinic. Following consultation, an automated script extracted each problem statement which was manually coded using the 'disorder' concepts from SNOMED CT (UK edition). Results: The review identified 298 relevant endocrine diagnoses, 99 findings and 142 procedures. There were a total of 88 (29.5%) commonly seen endocrine conditions (e.g., Graves' disease, anterior hypopituitarism and Addison's disease) and 210 (70.5%) less commonly seen endocrine conditions. Subsequently, consultant endocrinologists completed a survey regarding the common endocrine conditions; 28 conditions have 100% agreement, 25 have 90%–99% agreement, 31 have 50%–89% agreement and 4 have less than 59% agreement (which were excluded). Conclusion: Automated text parsing of structured endocrine correspondence allowed the creation of a SNOMED CT reference set for common endocrine disorders. This will facilitate funding and planning of service provision in endocrinology by allowing more accurate characterisation of the patient cohorts needing specialist endocrine care.

Objective: To evaluate the use of two questionnaires assessing awareness of hypoglycemia, in a pediatric type 1 diabetes (T1D) population. Methods: Prospective observational study with children (aged 9‐18 years) and parents (for children aged 2‐11 years) answering the Gold and Clarke questionnaires assessing awareness of hypoglycemia. Psychometric properties of the questionnaires were evaluated, and the most appropriate cut‐off score to classify participants as having normal vs impaired awareness of hypoglycemia (IAH) was determined by ability to recognize subsequent hypoglycemia and hypoglycemia severity, documented in a 4‐week blood glucose diary. Questionnaires were readministered at follow‐up assessment approximately 1.5 years later. Results: In total, 112 participants (51% male) with median (IQR) age 13.7 (11.1‐15.8) years, T1D duration 4.7 (2.2‐7.8) years, and HbA1c 62 (57‐73) mmol/mol (7.8%) were included. Both questionnaires demonstrated acceptable psychometric properties. Using score ≥3 to classify IAH gave a prevalence of IAH of 41% (Gold) and 22% (Clarke). When classified using the Gold questionnaire, IAH participants had higher incidences of mild asymptomatic hypoglycemia, whereas with the Clarke questionnaire, they had higher incidences of clinically significant and severe hypoglycemia. Subgroup analyses confirmed these associations only in participants aged ≥9 years. Follow‐up was completed in 90% of the participants, and a change of awareness status was observed in 22% to 36%. Conclusions: The Gold and Clarke questionnaires may be used to assess awareness of hypoglycemia in pediatric T1D in those ≥9 years of age, but the more detailed Clarke questionnaire has higher specificity and is superior in predicting risk of clinically significant hypoglycemia.

Impaired awareness of hypoglycaemia (IAH) is an acquired complication of insulin therapy, which affects people with type 1 and insulin-treated type 2 diabetes mellitus, whereby the ability to perceive the onset of hypoglycaemia becomes diminished or absent. Deficiencies of the counter-regulatory hormonal responses to hypoglycaemia usually co-exist. The development of IAH and counter-regulatory failure greatly increases the risk of severe hypoglycaemia. Scoring systems have been developed that can be used in the clinical setting and assist with identification of this group of individuals at risk of severe hypoglycaemia. The mainstay of treatment of IAH is the scrupulous avoidance of hypoglycaemia., (Copyright © 2010 Elsevier Masson SAS. All rights reserved.)
