  2. Definition

    We have developed and externally validated a list of codes to identify childhood maltreatment. There are separate code lists for ICD 10 and Read codes.This definition encompasses neglect, physical and sexual maltreatment, and includes codes for genital mutilation, and child protection codes (read code list only).

    These codes were developed for children aged 0 to 18 years, unless otherwise specified. We identify childhood maltreatment using the concepts described below. Each coding system has multiple concepts corresponding to subtypes of maltreatment (neglect, physical, sexual, psychological and other).

    For Read Code lists within each subtype of maltreatment are:

    1. Core code lists that are to be included in all studies seeking to identify maltreatment
    2. Historical codes lists indicating historical maltreatment (e.g. history of child abuse).

    The latter should be excluded in studies seeking to identify incident (first ever) cases of maltreatment.

    This code lists has been externally validated against a clinical database of clinician confirmed hospital presenting maltreatment as the gold standard (John et al., in press). Our codes lists were developed from existing literature (e.g. Chandan et al., 2020; Chandan et al., 2019; Syed et al., 2022; Woodman et al., 2012), conducting our own searches for codes that may be indicate maltreatment, risk or cause for concern; and finally based upon clinician judgement. This list is more comprehensive than those previously published encompassing codes for genital mutilation and child protection codes (child protection codes in read codes only).

    In keeping with previous research, we tiered our code list into those strongly indicating maltreatment (current list), and those codes that may indicate possible or suspected maltreatment or potential vulnerability (See Possible Child Maltreatment) (Chandan et al., 2019; Syed et al., 2022).

    Neglect

    These code list refers to codes that unequivocally refer to maltreatment by neglect. These have been stratified by age (0-1 years and 0-18 years). Both of the core lists must be included to identify neglect. The decision to include historical codes must be made based on the individual study (see above)

    Physical Maltreatment

    This list refers to codes that unequivocally refer to Physical maltreatment. All codes for physical maltreatment refer to individuals aged 0-18 years with no further age stratification. The core list must be included to identify physical maltreatment. The decision to include historical codes must be made based on the individual study (see above).

    Psychological Maltreatment

    This list refers to codes that unequivocally refer to psychological maltreatment. All codes for psychological maltreatment refer to individuals aged 0-18 years with no further age stratification. The core list must be included to identify psychological maltreatment. The decision to include historical codes must be made based on the individual study (see above).

    Sexual Maltreatment

    This list refers to codes that unequivocally refer to sexual maltreatment. The core lists must be included to identify sexual maltreatment. The decision to include historical codes must be made based on the individual study (see above).

    Other Maltreatment

    This list refers to codes that unequivocally refer to maltreatment that doesn't fit into one of the above categories. All codes for other maltreatment refer to individuals aged 0-18 years with no further age stratification. The core list must be included to identify ‘other’ maltreatment. The decision to include historical codes must be made based on the individual study (see above).
