Outcomes | Data source: native field name | Missing (n) | Commentary of findings | Impact |
---|---|---|---|---|
Primary | ||||
Child in Need (CIN) status as of 31 March each year | NPD > CIN: Referral date | 1 | No data appear across one record—record to be excluded (this will apply to all fields below) Note: 34 records with dates prior to time point ranges (1997–2007). This is expected. | None |
NPD > CIN: Referral—no further action | 42 | No data collected in 2008/2009 time point (accounts for 38 records). Some blanks appear in 2009/2010 time point; however, the referral date on these records is prior to 1st April of that data collection year. *Assumption that time point cycle is Apr–Mar. | Low: assumption missing data indicate further action was required and that the child was in need | |
NPD > CIN: Reason for closure | 142 | No pattern—further investigation required | As above | |
Secondary a | ||||
CIN categorisation | NPD > CIN: Category of Abuse | 329 | Only data from 2008/2009 accessed in pilot. For main phase data from 2012/2003 will be accessed and also ‘NPD > CIN: Latest category of abuse’ will be included which may improve data quality. | Still to be determined |
Child looked after (CLA) status (1) | NPD > CLA: Category of need; Legal status; Placement; REC | 0 | All records returned are complete. | None |
Child Protection registration (plan) (1) | NPD > CIN: Child Protection Plan (CPP) Indicator | 195 | Expected—all missing from 2010/2011 time point onwards. Data not collected during these years. | Low: CPP flag can be determined from other fields |
NPD > CIN: No. of previous Child Protection Plans | 320 | No pattern to missingness. Only 11 records have a value recorded, 9 of these are zero. | As above | |
NPD > CIN: Child Protection Plan start date | 320 | Expected—not all children will have had a CPP. Only 11 records have a date recorded, these correspond with data captured in the ‘no. of previous CPPs’ above. | As above | |
NPD > CIN: Child Protection Plan end date | 327 | Expected—only 4 records have an end date recorded. Corresponds with those records where a start date is recorded. Data check done—end dates are after the start date. | As above | |
Exploratory Markov chain modellingb | NPD > CIN: Date of initial child protection conference | 327 | Expected—not all children would have had a child protection conference. However further checks required to confirm validity of data. | Medium: Low numbers may impact analysis |
Injuries and ingestions | NHSD > A&E: A&E diagnosis (diag n) | 5981 | 45% missing (1650/6336 missing in BB trial—26% missing) | Medium: All diag/treat/inv. fields to be used in combination to define inj/ingc |

NHSD > A&E: A&E investigation (invest n) | 1728 | 13% missing (1396/6336 missing in BB trial—22% missing) | As above | |
NHSD > A&E: A&E investigation—2 char (invest n D) | 1712 | 13% missing (1395/6336 missing in BB trial—22% missing) | As above | |
