RESUMO

INTRODUCTION: Healthcare databases are a valuable source for epidemiological research in obstructive sleep apnoea, but accurately registered diagnoses are pivotal in contributing quality evidence. We examined positive predictive values (PPV) of the International Classification of Diseases, tenth version (ICD-10) diagnosis for "obstructive sleep apnoea" and "sleep apnoea" in the Danish National Patient Register. METHODS: Using the Danish National Patient Registry, we randomly sampled 100 patients from the North Denmark Region diagnosed with "obstructive sleep apnoea" (ICD-10 code DG4732) and 100 patients diagnosed with "sleep apnoea" (DG473*) during the year 2020. We calculated the PPV using a documented Apnea-Hypopnea Index (AHI) ≥ 5 to confirm the recorded diagnosis. A total of 70 patients were referred to the private sector for assessment of the AHI and excluded due to limited access to their data. RESULTS: The study population included 130 patients, among whom 64 were diagnosed with "obstructive sleep apnoea", and 66 patients were registered with "sleep apnoea". The PPV for "obstructive sleep apnoea" was 93.8% (95% confidence interval (CI): 85.0-97.5%), and the PPV for "sleep apnoea" was 80.3% (95% CI: 69.2-88.1%). CONCLUSIONS: Our findings indicated a high validity of the ICD-10 code DG4732 with a PPV of 93.8% and a lower PPV (80.3%) for the ICD-10 code DG473* for identifying patients with obstructive sleep. The "obstructive sleep apnoea" diagnosis is a suitable source of data for epidemiological research to identify patients with the disease. FUNDING: None. TRIAL REGISTRATION: Not relevant.

RESUMO

BACKGROUND: Food bolus obstruction (FBO) leading to hospital treatment is often associated with eosinophilic oesophagitis (EoE), stenosis, or oesophageal cancer (1). Danish national guidelines recommend that patients with FBO undergo a diagnostic upper endoscopy within two weeks of presentation to exclude possible malignancy, and histological evaluation of eight biopsies (2, 3). AIMS: The aims of this study were to (1) report the incidence and describe the causes and treatment of FBO in the North Denmark Region (NDR), (2) determine the proportion of patients who underwent upper endoscopy and biopsy according to regional and national guidelines, and (3) identify International Classification of Diseases 10th Revision (ICD-10) diagnosis and procedure codes applied to the hospital visits due to FBO in the NDR. METHODS: Among all acute hospital visits in the NDR in 2021, all visits with ICD-10 codes possibly reflecting FBO, as well as a random sample of 14,400 visits with unspecific ICD-10 codes (R and Z codes), were screened manually for possible FBO. Diagnosis, follow-up, and treatment of all patients with FBO were recorded. RESULTS: The median patient age was 66.0 (Q1-Q3: 49.8-81.0) years, and half of the patients had experienced FBO before. Two thirds of patients (66.0%) were never diagnosed with a cause of FBO, followed by 17.3% with EoE. 30% of patients did not undergo upper endoscopy within two weeks of the hospital visit, and 50.7% were never biopsied in the oesophagus. Of 1886 hospital visits with registry ICD-10 codes that possibly reflected FBO, 8.4% were due to FBO, while FBO was present in 0.028% of the random sample of unspecific ICD-10 codes. CONCLUSIONS: Most hospitalized FBO patients in the NDR in 2021 were never diagnosed with a cause. In these patients there is a high risk of overlooked EoE or upper gastrointestinal cancers. The area needs immediate focus and changed routines to improve treatment and prevent new FBO.
