Accident Dashboard
The Accident Rate dashboard offers you a global view of your organisation’s accident rate through the four standard prevention indices (frequency, severity, incidence, and average duration), their month-by-month evolution, and their comparison with company targets.
You will only see data from the companies, centres, and sections to which you have access according to your user profile. Two different people may see different figures on the same dashboard, and this is expected.
Key Concepts
Section titled “Key Concepts”Before reviewing each element, it is useful to clarify several concepts used throughout the dashboard.
The four accident rate indices. The entire dashboard revolves around four indices calculated from accidents with sick leave, days of sick leave, hours worked, and the number of exposed workers:
| Index | What it measures | How it is calculated |
|---|---|---|
| Frequency Index (IF) | How many accidents with sick leave occur per million hours worked. | Number of accidents with sick leave × frequency constant ÷ hours worked. |
| Severity Index (IG) | How many working days are lost per thousand hours worked. | Lost working days (days of sick leave) × severity constant ÷ hours worked. |
| Incidence Index (II) | How many accidents with sick leave occur relative to the number of workers. | Number of accidents with sick leave × incidence constant ÷ number of workers. |
| Average Duration Index (IDM) | How many days, on average, each accident’s sick leave lasts. | Lost working days (days of sick leave) × average duration constant ÷ number of accidents with sick leave. |
The constants for each index (for example, the million hours in the frequency index) are configured in each organisation’s settings, so they may vary from one client to another.
What counts as an accident. The dashboard counts accidents with sick leave: those whose accident type is marked as sick leave, which are not relapses, and which are not in itinere accidents (commuting accidents). Incidents without sick leave are not included in the indices.
Where the data comes from. The indices are built from the record of hours worked (hours, number of workers, and days of sick leave entered monthly by company, centre, section, and position). Accident investigations are linked to this record. This has two important consequences:
- The dashboard’s time axis (month and year) is that of the hours record: each accident is assigned to the month it occurred and associated with that month’s hours record and scope.
- If for a given month and scope no hours are recorded, there is nothing to display; and an accident only enters the indices if the corresponding hours record exists. Keeping the hours worked record up to date is therefore a necessary condition for accurate accident rate calculation.
Active and inactive elements. Unlike other dashboards, this one does not hide inactive companies, centres, sections, or positions: if they have recorded hours, they also appear in the scope filter and in the data.
Monthly value and accumulated value. Each index is shown in two ways. The monthly value corresponds only to that month. The accumulated value sums accidents, days of sick leave, and hours from the start of the period, so each month reflects the index for the entire period up to that date. The accumulated value tends to stabilise over the year, while the monthly value is more sensitive to occasional peaks.
Company targets. Each organisation can set a target for each index. These targets are the reference values against which the actual indices are compared in the indicators.
Scope permissions. The dashboard only includes accidents from the companies, centres, and sections to which you have access. Therefore, two users with different permissions may see different figures.
Chained filters. All filters apply simultaneously to all charts, cards, and tables. If you select a centre and a year, everything you see on screen recalculates only with accidents from that centre and year.
Filters
Section titled “Filters”On the left side you will find the filters. All allow multiple selection.
| Filter | What it allows you to narrow down |
|---|---|
| Scope | The organisational structure, in tree form: company → centre → section → position. You can select any level; for example, an entire centre or a specific position. |
| Year | The time period, according to the data date. Includes a search box to locate values quickly. |
| Range | Narrows the data’s age relative to today: last 12 months, between 12 and 24 months, or more than 24 months. It is a single-selection filter. |
Indicators
Section titled “Indicators”At the top centre, the Indicators panel shows the four indices for the period as semicircles (gauges), each compared with its company target:
- Frequency Index
- Severity Index
- Incidence Index
- Average Duration Index
Each indicator presents the actual value reached in the period and, alongside it, the target set by the company, along with the absolute and percentage deviation from that target. It serves to see at a glance whether the organisation is within or outside its goal for each index.
Accumulated Indicator Cards
Section titled “Accumulated Indicator Cards”Next to the table are four cards summarising the accumulated value of each index for the selected period and filters:
- Accumulated Frequency Index
- Accumulated Severity Index
- Accumulated Incidence Index
- Accumulated Average Duration Index
Each card shows the accumulated index value, its variation (absolute and percentage), and a small trend graph (sparkline) that allows you to see at a glance whether the index has been rising or falling over the period.
Temporal Evolution Charts
Section titled “Temporal Evolution Charts”There are four charts, one per index, showing how accident rates evolve month by month. Each shows two series: the monthly value of the index (only that month) and the accumulated value (from the start of the period to that month). Only months up to the current month are shown; no future data is projected.
Frequency Index
Section titled “Frequency Index”Monthly and accumulated evolution of the frequency index. Allows detection of which months have concentrated accidents with sick leave relative to hours worked.
Incidence Index
Section titled “Incidence Index”Monthly and accumulated evolution of the incidence index. Relates accidents to the number of exposed workers, helping to compare centres or sections of different sizes.
Severity Index
Section titled “Severity Index”Monthly and accumulated evolution of the severity index. Reflects the weight of lost working days: it rises when accidents cause long sick leaves, even if few in number.
Average Duration Index
Section titled “Average Duration Index”Monthly and accumulated evolution of the average duration index. Indicates how many days, on average, each accident’s sick leave lasts; useful for assessing the severity of accidents regardless of their number.
Table: Yearly Evolution
Section titled “Table: Yearly Evolution”The table summarises the four accumulated indices grouped by year, ordered from the most recent to the oldest year.
| Column | What it shows |
|---|---|
| Year | The year to which the data corresponds. |
| IF | Accumulated frequency index for that year. |
| IG | Accumulated severity index for that year. |
| II | Accumulated incidence index for that year. |
| IDM | Accumulated average duration index for that year. |
Each index column is accompanied by a coloured bar that facilitates comparing values between years at a glance.
Frequently Asked Questions
Section titled “Frequently Asked Questions”Why does the accumulated value not match the sum of the monthly values?
Because the accumulated index is not the sum of the indices for each month: it is recalculated by first summing the accidents, days of sick leave, and hours for the period, and then applying the index formula. Summing monthly indices would give an incorrect result.
Why does an incident we had not appear reflected in the indices?
Because the indices only count accidents with sick leave. Incidents without sick leave, relapses, and in itinere accidents are excluded from the calculation.
Why do my figures not match those of a colleague?
The dashboard applies each user’s scope permissions: only accidents from the companies, centres, or sections you have access to are included. Two users with different permissions will see different figures.
Why does an index appear very high in a particular month?
The indices relate accidents (or days of sick leave) to hours worked or number of workers. In months with few hours worked, a single accident can spike the monthly value. For a more stable reading, look at the accumulated value.
Why does the severity index (or average duration index) in the Indicators panel not match that in the chart or table?
Because days of sick leave come from two different sources. The Indicators panel calculates severity and average duration from the lost working days recorded in each accident investigation, while the charts, cards, and table calculate them from the days of sick leave in the monthly hours record. If these two values are not aligned (for example, because the lost working days from an investigation have not yet been reflected in that month’s hours record), the severity and average duration indices may differ between the Indicators panel and the rest of the dashboard. The frequency and incidence indices are not affected, as they do not depend on days of sick leave.
What does it mean if an indicator is above or below the target?
The target is the goal set by the company for that index. For frequency, severity, incidence, and average duration, the lower the actual value relative to the target, the better the result.
