Identifying cases & Quality Assurance: Data Completeness & Accreditation The Trauma Audit & Research Network (TARN) Data Collection session
2
Identifying cases: 2 case studies
3
System 1: Retrospective Data capture Clinical (ICD10) codes Clinical coding departments use a coding system called ICD10 ICD10: International Classification of Diseases ICD10 codes document: Admission reason (Injury, Medical, Elective, Complication) ICD10 codes that begin with S or T indicate injury e.g. S82.2: fracture to shaft of tibia S82.21: open shaft of tibia S82.20: closed shaft of tibia T055: Traumatic amputation of both legs
4
Trust IT dept. can therefore generate weekly spreadsheet showing: Patients discharged previous week with any S or T ICD10 code Filtering out: <3 days stay, discharge destination = home 65+ isolated NOF 65+ isolated pubic rami fracture Minor injuries Full list of all applicable ICD10 codes: www.tarn.ac.uk/resourceswww.tarn.ac.uk/resources Result: List of potential TARN patients Check imaging reports to ensure inclusion System 1: Retrospective Data capture Clinical (ICD10) codes

System 1: Retrospective Data capture Clinical (ICD10) codes: Advantages Captures patients who bypass ED (transfers in, GP admissions) TARN can liaise with IT to help set this up: SQL script Limited staff resource required Used by most Trauma Units who employ Retrospective data capture Used as backup to “live” data capture by most Major Trauma Centres
8
Only admitted patients are assigned an ICD10 code Transfers out from ED Deaths in ED Separate system required to capture these Accuracy of Trust ICD10 coding Use of NOS (not otherwise specified) codes can increase potential cases Cases admitted for Rehabilitation only – not easily identified Delay between discharge and clinical coding System 1: Retrospective Data capture Clinical (ICD10) codes: Disadvantages

System 2: Live Data capture Employed by Royal Stoke University Hospital Major Trauma Centre North West Midlands & North Wales Major Trauma Network
10
System 2: Live Data capture Employed by Royal Stoke University Hospital Major Trauma Centre Diary in Resuscitation completed by ED Consultant. Data Co-ordinators pagers that receive Trauma Calls. ED system search: Patients who were imaged & admitted. Daily contact with relevant Wards: Notification of any trauma patients admitted. Attend morning Orthopaedic/Neurosurgical case discussion meetings. Liaise with Rehabilitation Co-ordinators re: Trauma patients seen on wards When eligible cases identified: Early care data collected on forms by TNC & Data coordinators whilst still inpatient. Later care data (Operation, ICU, Imaging, Ward, Discharge data) taken from online systems.
11
System 2: Live Data capture: Advantages Employed by Royal Stoke University Hospital Major Trauma Centre Very little backlog; patients often dispatched to TARN day after discharge. Case notes only required for “missed” cases identified post discharge. Regular communication between Coordinators & Clinicians. Rehabilitation Co-ordinators involved very early on. Deaths data: Available from Bereavement office quickly, no waiting for inquest.
12
System 2: Live Data capture: Disadvantages Employed by Royal Stoke University Hospital Major Trauma Centre Greater staff resource required Post discharge ICD10 report required to capture “missed” patients.
13
Collecting the data Retrospective Data Entry: Post discharge Access to electronic Imaging and Theatre systems required Enter data directly from notes or use Pro-forma CORE PROFORMA IN REPORTS SECTION OF WEBSITE DO NOT have to start and finish a submission in one session
14
Quality Assurance Data Completeness (quantity) & Data Accreditation (quality)
15
Data completeness % Measure of Expected v Submitted number of cases HES Data used to calculate expected no. of cases per Trust HES = Hospital Episode Statistics database HES data contains ICD10 codes assigned by Trusts in previous year: 2013 TARN Inclusion criteria applied to HES data No. of Expected cases then derived Expected number of cases used as a guide only. Not a 100% target! All eligible cases should be submitted to TARN
16
Data completeness % Measure of Expected v Submitted number of cases % of expected v submitted cases shown on TARN website Updated every 4 months: End of March July November Shown as Trust and individual Hospital figures Should always be viewed alongside Hospital Survival rate
17
Data Completeness calculation Data Completeness 76.1% Submissions: NUMERATOR238 Expected submissions: DENOMINATOR313 Data completeness76.1% HES dataset/ Denominator TARN submissions/Numerator 1-49%: May not reflect true practice 50-79%: May not reflect true practice 80%+: View with confidence
18
Improving Data completeness HES v TARN 2013 Data comparison exercise
19
HES v TARN 2013 comparison exercise Comparison spreadsheet produced: Green: Cases appear in both datasets (Submission ID shown) Black: Cases appear in HES dataset only (not submitted in TARN) ‘Not TARN eligible’ field: Completed by Trust & Fed-back to TARN Missing cases: Issues identified & entered: Increase in Numerator Ineligible cases: Removed from expected no. of cases: Decrease in Denominator
20
HES v TARN 2013 comparison exercise results Commonly missed groups: Aged 65+ Hip fractures with other (non hand or foot) fracture Traumatic SDH admitted to medical wards Aged 65+ Pelvic fractures Spinal fractures Patients whose LOS is exactly 3 days Common reasons for the variance between the HES and TARN: Inaccuracies in ICD10 coding Old injuries being coded. Use of NOS (Not Specified) codes, which varies from trust to trust Rehabilitation only admissions Elective admissions 45 Trust participated in exercise >3,700 cases removed from Expected no. of cases 18% reduction & comparable Data Collection increase
21
Data Accreditation % (quality) Measure of frequency of CORE data field completion CURRENT ACCREDITATION FIELDS Glasgow Coma Score or Intubation/ventilation (Pre Hospital or ED) Incident or Call 999 Date/time Arrival time Transfer: Reason & Date of Referral CT time Operation: Start time, grade & speciality of surgeon & grade of anaesthetist ED Doctors: Time seen, grade & speciality Injury detail – proportion of NFS codes
22
NEW ADDITIONS TO ACCREDITATION FIELDS *Pre-existing conditions **Pupil reactivity for patients with AIS 3+ (Serious) head injuries Data Accreditation%: Recent additions From December 2014 onwards * New Probability of Survival (Ps)14 model ‘Other’ and ‘Not Known’ detrimental to Data Accreditation **Future Probability of Survival model
