From CHIF IS data selection according MDS is available since the 1st of June 2011 these data covers only hospital discharges. Since 2013 data according MDS from emergency departments in hospitals (ED) is partly available as well (not all ED started coding injuries and external cause since 2013 01 01).
6	Data file name (MDS)	JAMIE_MDS_2013_LT.txt
7	Date of creation of MDS file	2014 05 26
8	Range of data of attendance	2013 01 01 - 2013 12 31
9	Original coding dictionary	ICD-10-AM (Australian modification), 1st of July 2008. Prepared conversation tables ICD-10-AM -> IDB MDS.
10	Dictionary modifications	Prepared conversation tables ICD-10-AM -> IDB MDS.
11	Bridge coding applied	ICD-10-AM -> IDB MDS
12	No. of records in the data file	246582
13	No. of MDS reference hospitals	103
14	Geographic scope	99% of the entire reporting country
15	Hospital characteristics used for a representative sample of hospitals	All hospitals, which has contract with the State Patient Fund and entering data into CHIF IS; all registered injuries in acute care beds (rehabilitation and nursing cases excluded) and in emergency departments in hospitals.
16	Sampling of cases within hospitals	99%
17	Percentage of admissions in data file	14.3% In 2013 all ED started register injuries since 2013 07 01 and during this period 129487 cases were registered. Therefore we take period 2013 07 01 – 2013 12 31 for admission calculation: 21690 cases were registered. Percentage of admissions in 2013: (21690/(21690+129487))*100=14.3%.
18	Relative sample size (admissions)	99.9%
19	Relative sample size (ambulatory treatments)	78.3% In 2013 all ED started register injuries and their external causes since 2013 07 01 and during this period 129487 cases were registered (during all year cases from ED should be about 29487*2=258974 cases of injuries) but quite big part of ED started register injuries since 2013 01 01 and during all year of 2013 – 202840 cases were registered. Coverage of out-patients in ED of all year is about (202840/258974)*100=78.32%.
20	Minimum Quality Control Checks	y
21	Average percentage of “unknown””	15.6% For average calculation have been taken all elements from data file JAMIE_MDS_2013_LT.txt (except: provider (hospital) code, permanent country of residence, nature of injury 2, part of the body injured 2, narrative)
22	Method for extrapolation from sample to national incidence	Sampling has not been done. Selected all hospital discharges from CHIF IS which covers 99% of all hospitals discharges (99.9% of acute injuries). Selected all ED from CHIF IS, but in 2013 not all ED started coding injuries since 2013 01 01, data coverage is about 78.3%.
23	Reference population data provided	Y Is it correct to use population statistics by 1 January of each year for reference population data file? Because for calculation of rates we mostly use average population statistics and in case we do not have this statistics we use population statistics at the end of year (this is equal to population statistics by 1 January of next year).
