For each hospitalised patient, the hospital charts are reviewed, dates of admission and discharge and main diagnoses are extracted, coded by coding staff and collated nationally into HES.
Associated numbers of HNC hospitalizations, health care resource use, and unit costs were identified and extracted using the ICD-10 codes C01 C06, C09 C14, and C32 as the main diagnoses, henceforth called "cancers of interest".
Associated numbers of HNC hospitalizations, health care resource use, and costs were identified and extracted using the International Classification of Diseases, tenth revision (ICD-10; World Health Organization, Geneva, 1990) codes C01 C06, C09 C14, and C32 as the main diagnoses.
Main diagnoses were somatoform disorders (17.6%), phobias (12.9%), substance use disorders (10.9%), and depression (8.3%).
The main diagnoses were cardiac arrest (28), trauma (27) and congestive heart failure (10).
Cardiovascular disease (CVD) and injuries were the main diagnoses and constituted half of all operations.
The main diagnoses are given according to the diagnostic hierarchy in ICD-10 giving priority to diagnoses with lower ICD-10 codes (World Health Organisation [1992]).

Bronchiolitis and pneumonitis were the main diagnoses.
Only main diagnoses were included in the study.
