3.1. Data description | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Harmonised data on accidents at work are collected in the framework of the administrative data collection 'European Statistics on Accidents at Work (ESAW)', on the basis of a methodology developed first in 1990. An accident at work is defined as 'a discrete occurrence in the course of work which leads to physical or mental harm'. The data include only fatal and non-fatal accidents involving more than 3 calendar days of absence from work. If the accident does not lead to the death of the victim it is called a 'non-fatal' (or 'serious') accident. A fatal accident at work is defined as an accident which leads to the death of a victim within one year of the accident. The variables collected on accidents at work include: - Economic activity of the employer and size of the enterprise |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
3.2. Classification system | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
The following classifications are used in ESAW:

3.4. Statistical concepts and definitions | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
European Statistics on Accidents at Work (ESAW) are based on case-by-case data for accidents at work resulting in more than 3 days' absence from work or death of the victim. An accident at work is a discrete occurrence in the course of work which leads to physical or mental harm'.
A non-fatal accident has to be counted as an accident for ESAW, if it resulted in more than 3 days absence from work. Because in Switzerland there is a three days waiting period before dayly allowances are paid, the ESAW definition is transformed into a minimum of one day's daily allowances to be paid. A fatal accident at work is defined as an accident that leads to the death of a victim within one year of the accident. If the accident is registered as having fatal consequences within the calendar year following the accident, it is considered a fatal accident to ESAW. The ESAW methodology is in accordance with the ILO (International Labour Office) "Resolution concerning statistics of occupational injuries (resulting from occupational accidents)" adopted by the Sixteenth International Conference of Labour Statisticians in October 1998. The following 15 phase I and II variables have to be sent by Member States to Eurostat from reference year 2011 onwards on an annual basis: 1. Case number In addition, three of the following nine phase III variables on 'causes and circumstances of the accident' have to be sent annually to Eurostat from reference year 2013 onwards: 16. - 18. Workstation, Working Environment, Working Process Finally, the weight on Causes and Circumstances has to be sent if the Member State applies an additional sampling for the encoding of the ESAW Phase III variables on causes and circumstances. If not applicable the default value is 1. The definition of the variables is stated in the Commission Regulation (EU) No 349/2011 and further specified in the ESAW methodology. |

3.5. Statistical unit | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Data are collected for each accident. If a person is a victim of more than one accident during the reference year, several cases are reported (one for each accident). If there are several victims in the same event of accident, also several cases are reported (one for each victim). |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
3.6. Statistical population | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Data on employed resident population is reported to ESAW, but not on self-employed and family members if working on an informal basis. Students and family members having work contracts are included. Armed forces of Switzerland are not included. |

7.1. Confidentiality - policy | |||
Confidentiality is regulated by Swiss legal framework through, among others: - Unfallversicherungsgesetz (UVG) - Verordnung über die Unfallversicherung (UVV) - Verordnung über die Statistiken der Unfallversicherung (VSUV) - Bundesgesetz über den Datenschutz (DSG) Regulation (EC) No 223/2009 on European statistics (recital 24 and Article 20(4)) of 11 March 2009 (OJ L 87, p. 164), stipulates the need to establish common principles and guidelines ensuring the confidentiality of data used for the production of European statistics and the access to those confidential data with due account for technical developments and the requirements of users in a democratic society. Commission Regulation (EU) No 557/2013 of 17 June 2013 implementing Regulation (EC) No 223/2009 of the European Parliament and of the Council on European Statistics as regards access to confidential data for scientific purposes and repealing Commission Regulation (EC) No 831/2002 Text with EEA relevance, 'establishes the conditions under which access to confidential data transmitted to the Commission (Eurostat) may be granted for enabling statistical analyses for scientific purposes, and the rules of cooperation between the Commission (Eurostat) and national statistical authorities in order to facilitate such access' (article 1). |
|||
7.2. Confidentiality - data treatment | |||
Microdata of Member States are sent via secure e-Damis application. The microdata as received by Eurostat from the National Statistical Institutes or other statistical authorities do not contain any administrative information such as names or addresses that would allow direct identification. Access to this microdata is nevertheless strictly controlled and limited to specified Eurostat staff. Currently, there are no restrictions applied when publishing aggregated data. |
|
|||
8.1. Release calendar | |||
Eurostat disseminates accidents at work data by the occurrence concept as soon as possible after data have been transmitted by a country and validated by Eurostat. When all countries have sent their data for a certain reference year, Eurostat calculates EU aggregates and releases them and all other indicators. This usually takes place in the last quarter of each year. ESAW data is usually released between January - September of each year (in year N+2, where N is the reference year in which the accidents took place), with a focus on end of June - July (release of most countries' data). There is no specific release calendar for ESAW data (see the Eurostat website for all published ESAW data). See section 14 Timeliness and punctuality for more details about the timing and punctuality of ESAW data releases. |
|||
8.2. Release calendar access | |||
Not applicable. |
|||
8.3. Release policy - user access | |||
In line with the Community legal framework and the European Statistics Code of Practice Eurostat disseminates European statistics on Eurostat's website (see item 10 - 'Accessibility and clarity') respecting professional independence and in an objective, professional and transparent manner in which all users are treated equitably. The detailed arrangements are governed by the Eurostat protocol on impartial access to Eurostat data for users. |

13.1. Accuracy - overall | |||
The number of notifications is highly accurate in Swiss ESAW data. The time lag between accidents and their notifications to the insurance did not change much in recent years. There are no significant differences in the number of notifications resulting from this. |
|||
13.2. Sampling error | |||
IMPORTANT: In Swiss ESAW data sampling only applies to phase II and III variables available in Swiss data. A good approximation for the relative sampling error of avaiable phase II and III variables is the coefficient of variation (CV) = 1/SQRT(N), where N is the unweighted number of cases. Examples: Raw number of N=100 cases: CV = approximately 10%. Raw number of N=10,000 cases: CV = approximately 1%.
Sampling error - indicators Coefficient of variation (CV) = 1/SQRT(N), where N is the unweighted number of cases.

|||
14.1. Timeliness | |||
The legal requirement for Member States is to send Eurostat ESAW data until 30 June of year N+2, where N is the reference year in which the accidents took place. Data from Switzerland unfortunately are delayed by approximately 3 months due to the delayed data entry process for the detailed sample variables. As soon as one or several Member States have sent their data they are published on the Eurostat website. In some cases this may happen already some months before the legal deadline of June. |
|||
14.1.1. Time lag - first result | |||
Approximately 18 months after the end of the reference year (experience of previous years, but recently 20+ months). |
|||
14.1.2. Time lag - final result | |||
Approximately 18 months after the end of the reference year (experience of previous years, but recently 20+ months).
|
|||
14.2. Punctuality | |||
Most countries transmit data before and a few days - weeks after the legal deadline of 30 June of year N+2. Eurostat then checks and validates this data and publishes most of it on its website within a few weeks (in July N+2 or before). A few countries may send data only during July - September of year N+2. Data from Switzerland unfortuantely are delayed by approximately 3 months due to the delayed data entry process for the detailed sample variables. |
|||
14.2.1. Punctuality - delivery and publication | |||
Approximately 18 months after the end of the reference year (experience of previous years, but recently 20+ months). |
|
|||
15.1. Comparability - geographical | |||
Regarding comparability of data from Switzerland to those from other countries see a discussion of several aspects in https://www.unfallstatistik.ch/d/publik/unfstat/pdf/Ts21.pdf#page=61 |
|||
15.1.1. Asymmetry for mirror flow statistics - coefficient | |||
Unknown |
|||
15.2. Comparability - over time | |||
Comparability of Swiss ESAW data since 1984 is good, since no major changes in legislation took place. However, all changes in classification systems for ESAW variables (such as for NACE from Rev1 to Rev2, from ISCO-88 to ISCO-08) have some impact on comparability over time, depending on the time the year took place in a country. |
|||
15.2.1. Length of comparable time series | |||
Comparability of Swiss data since 1984 is good, since no major changes in legislation in this time range. For a subset of todays universe, time series can go as far back as 1918 for some variables. |

18.1. Source data | |||
Swiss data set is based on administrative insurance data sources. Data on cases, costs, and covered employers are transmitted from the insurer to SSUV on a yearly basis. Some phase II and phase III variables are obtained from case files. From all cases a sample is drawn, and for this sample complete case files are transfered to SSUV for a closer statistical evaluation. Coding of these sample cases is performed by a specialized SSUV coding staff. |
|||
18.2. Frequency of data collection | |||
Continous |
|||
18.3. Data collection | |||
Administrative insurance data on cases, costs, and covered employers are transmitted from the insurer to SSUV. Some phase III variables are obtained by coding directly from case files. Coding is performed by specialized SSUV staff. |
|||
18.4. Data validation | |||
Various automatic and manual checks are performed on data upon reception at SSUV in order to identify possible errors and inconsistencies with the ESAW methodology. Insurers are asked to check all inconsistencies and corrections and re-send data if necessary. Validation activities at SSUV include:
|
|||
18.5. Data compilation | |||
IMPORTANT: The weight mentioned below is only used for available phase III variables. The related sample of some phase II and all phase III variables consists of several subsamples:
The weight is reciprocal to the probability of a case to be in the sample, i.e. the weight is 1 for all fatal and permanent cases, and 20 for the rest of the sample.
