EDISON needed to improve the speed of pre-shift health screenings. They designed and implemented an automated health checkup system.

CHALLENGE: Improving the speed and accuracy of pre-shift health screenings

Every year, over 374 million people are injured at work, accounting for 3.94% of global GDP per year, according to the International Labour Organization. Industries particularly vulnerable to these injuries are manufacturing, mining, transportation and animal production.

Most of these workplace injuries are easy to prevent through proper health screenings of workers by medical professionals before their shift begins. After all, health screenings prevent personnel who are under the influence from working.

But manual pre-shift screenings are time-consuming and prone to human error:

  • The number of medical staff should be proportional to the number of workers subject to the examination
  • Doctors and nurses are prone to human error
  • Manual screenings are vulnerable to bribery and corruption
  • Workers may become aggressive because of failed tests

SOLUTION: Automated pre-shift health screenings

EDISON Software Development Centre set out to solve this problem using a novel approach – developing custom software and automating the health screening process.

The solution is electronic health checkup system (EHCS). The EHCS checks for standard medical indicators: blood alcohol levels, body temperature, pupil dilation and blood pressure.

How EDISON did it

Using a variety of programming languages and application software, EDISON created a three-level system incorporating a user interface, web server, and medical database allowing for a comprehensive network that connects and facilitates communication among all relevant stakeholders and medical measurement equipment.

“The task was urgent. Our engineers suggested novel solutions, which made the system work. We followed the hourly rate plan and provided our client with tracking tools. We believe transparency at work brings discernible progress and we constantly pursue this honest approach.” – explains Tommy Karyukin, Sales Director at EDISON Software Development Centre.

A project team of 10 members designed and implemented the automated pre-shift health screenings. EDISON’s software engineers completed the EHCS project on time. Workflow took 22 months and 6,986 person-hours efforts. Certain debugging tasks were solved with involvement of 16 software engineers.

The medical terminals have the following equipment:

  • Desktop PC
  • Contour chair
  • Breathalyzer
  • Blood Pressure Monitor
  • Thermometer
  • Custom-made pupillometer (used to measure pupil dilation and responsiveness)
  • Full HD camera

For workers, automated screenings are quick and non-invasive.

Workers approach a medical terminal and identify themselves using an ID, after which the machine begins its assessment.

If all measurements are within acceptable ranges, the worker receives a printed confirmation which allows them to enter the facility floor. If the worker fails, the EHCS bars them from entering the production floor. The worker is ushered to a medical professional who will investigate further.

How EDISON tackled cheating attempts

As any safety officer can attest to, attempts to cheat on pre-shift safety checks are common. Here’s how EDISON addressed attempts to cheat by workers.


Common methods used by workers to beat the breathalyzer included:

  • Breathing in instead of out
  • Controlling breath so that the breathalyzer doesn’t get an accurate reading, also known as under-breathing

None of these methods proved successful in tricking the software.

Pupillometry Test

Pupillometry tests are used to measure pupil dilatation, which shows drug-induced intoxication and exhaustion levels.

Workers tried to trip up the system by blinking and shifting eyes. EDISON’s software engineers updated the system so that the pupillometry test is not vulnerable to manual interference.

Identification Procedure

Although the first iteration of the EHCS included an ID check, some workers still attempted to beat the system by asking a friend to take their place during the health screening.

To prevent these attempts from being successful, the software engineers included video recording and a facial recognition module.

BENEFIT: Administer health screenings to your workers in minutes

With automated Electronic Health Checkup System, businesses can carry out mass pre-shift health screenings within minutes.

Other benefits include:

  • Reduction in medical personnel
  • Impartiality of checkup results
  • Cost-savings
  • Reduction in workplace injuries and mishaps

Automated health checkups ensure:

  • Only fully capable, sober and healthy personnel can enter the production facility
  • Reduction in medical personnel
  • Impartiality of checkup results

“Public transport drivers, machine operators, aircraft crew, security guards have safety as a main duty and are responsible not only for themselves. Since we joined the project, we realized EHCS is not about saving time, it’s about saving lives,” – notes Jannet Samerkhanova, Marketing Coordinator at EDISON.
