Target phenotype Anorectal malformations
Dataset HES APC and mortality
Datafields diag, opertn
Summary Anorectal malformations affecting the anus, rectum and genitourinary system. To be included, a diagnosis or procedure code must be recorded in HES APC in the first year of life or a diagnosis code must be recorded in mortality data in the first year of life (either a “specific” diagnosis code or a “generic” diagnosis code with supporting evidence by way of a “specific” diagnosis code additionally in HES APC). One of the differential diagnosis codes must NOT be recorded in the first year of life.
Validation Diagnostic and procedure codes extracted by paediatric surgeons from previous research using administrative data.
Original purpose To estimate the birth prevalence of anorectal malformations, their risk factors and 5-year outcomes.
Groups Specific or generic (with most OPCS-4 generic codes labelled as stoma creation).
Flags age_less_than_1 = code must be recorded in the first year of life (i.e., before the first birthday) (applies to all codes). differential_diag = code is not valid if one of the differential diagnosis codes is present (applies to all codes). diag_and_opertn_req = in HES APC, one of the diagnosis and one of the operation codes must be recorded in the first year of life; in mortality data, one of the specific diagnosis codes must be recorded (and an operation code is not needed) OR a generic code is recorded in mortality data plus a specific code in HES APC (applies to all codes).
Other details In Ford et al’s original paper, cases were classified as isolated or complex depending on the presence of additional congenital anomaly codes recorded during the first year of life. These are the Q-block codes from Hardelid et al with the exception of the Q-block codes that are included in this list.
Changes from original Two procedure codes were removed as these are incorrectly labelled as OPCS-4 codes when they are in fact codes in the Clinical Coding & Schedule Development Group’s list, used by private providers.
