National IDB File Information (Minimum Data Set)

1	Country	Italy
2	Year	2012
3	National Register Name	EMUR - National Health Service Emergency Data Flow: A) ED register; A) 118 Rescue Service Register;
4	Purpose of the register	The Ministry of Health has established by decree a national Minimum Data Set for the EDs current registers. It’s based essentially on the hospital EDs registers and the 118 emergency rescue service registers.
5	Scope of the register	In the ED register all the attendances for injuries are recorded. The 118 service registers only the cases sent to hospital (essentially by ambulance or helicopter) by the 118 operators. No other systematic deviation except 118 cases selection.
6	Data file name (MDS)	ITA_2012_MDS.txt
7	Date of creation of MDS file	20140627
8	Range of data of attendance	20120101-20121231
9	Original coding dictionary	IDB-JAMIE manual (Version August 7th, 2012 )
10	Dictionary modifications
11	Bridge coding applied	ICD9CM>MDS. We developed a bridge coding table from ICD-9-CM (ver. 2007) to JAMIE-MDS based on the Barrel’s matrix.
12	No. of records in the data file	140370
13	No. of MDS reference hospitals	95
14	Geographic scope	Italy (sample covering 15.7% national pop. High concordance sex-age distribution and pop. density).
15	Hospital characteristics used for a representative sample of hospitals	All hospitals in Piedmont, Tuscany and Abruzzo served by the 118 Rescue Service: the largest hospitals. They account for 89.1% of the whole injury inpatients in the 3 regions. Those hospitals account for 43.0% of all the hospitals having cases of admission for injuries
16	Sampling of cases within hospitals	We included all 118 service database records (13.0% of the whole injury ED attendances) the only ED cases with information on the mechanism of injury. A possible selection bias refers to the greater severity of injuries (on average) than the rest of the ED cases.
17	Percentage of admissions in data file	18.6% (expressed as the ratio of no. of admissions to all ED attendances due to injury in the 118 sample x 100)
18	Relative sample size (admissions)	2.8% distribution (expressed as the ratio of no. of admissions in the 118 sample to total no. of hospital discharges due to injuries in Italy x 100)
19	Relative sample size (ambulatory treatments)	1.9% distribution (expressed as the ratio of no. of 118 sample attendances at ED to total no. of attendances at ED due to injury in Italy x 100)
20	Minimum Quality Control Checks	Yes
21	Average percentage of “unknown””	11.6% (narrative description not included).
22	Method for extrapolation from sample to national incidence	The method for extrapolation from sample to national incidence is based on national figures of injury cases of hospital admissions.
23	Reference population data provided	Yes
