Health surveillance software, from exposure group to result

MyC schedules surveillance per worker from their exposure group, with due dates and expiry alerts. Results from connected audiometers and spirometers land in the worker's health record and can be compared with their own baseline, employees and contractors alike.

What health surveillance software does

Health surveillance is a program of repeated health checks for workers who remain exposed to a hazard after controls are in place, used to identify ill health caused by work. In the US, specific OSHA standards, such as those for respirable crystalline silica and lead, require employers to make medical surveillance available to exposed workers, each with its own triggers, tests and schedule. Health surveillance software, also called medical surveillance software, runs that program for each worker: who needs which exam, when it is due, what the results show and what happens next.

  1. 01

    Group workers by exposure

    Workers who do similar tasks, with the same substances, in a similar environment form a similar exposure group. The group's hazards set the surveillance each member needs.

  2. 02

    Schedule each worker's exams

    Surveillance usually starts with a baseline before or soon after exposure begins, then continues with periodic checks at the interval each hazard calls for.

  3. 03

    Run the checks

    Questionnaires, hearing tests, lung function tests and clinical exams are carried out by competent occupational health professionals.

  4. 04

    Compare results with the baseline

    Each result is read against the worker's own earlier results, such as a baseline audiogram, so a change like a standard threshold shift in hearing shows early.

  5. 05

    Act on findings

    A finding leads to follow-up: informing the worker, reviewing controls, a referral or a fitness-to-work review.

  6. 06

    Keep the records

    Surveillance records are kept for decades. In the US, OSHA requires the medical records of exposed workers to be kept for the duration of employment plus 30 years.

Definition: HSE. Medical surveillance: OSHA, 29 CFR 1910.1053(i) and 1910.1025(j). Retention: 29 CFR 1910.1020(d)(1).

How MyC runs health surveillance

From the exposure group to the result, every step of surveillance stays in one health record per worker, across sites and decades.

Explore the platformSee the occupational health EHR

Surveillance by exposure group

Surveillance is scheduled per worker from their exposure group, with due dates and expiry alerts. Exposure groups apply specific test and questionnaire templates.

Requirements by substance, job and site

Set health surveillance requirements by substance, job and site. Each site follows your company standard and is set up for its country's requirements.

Results against the worker's baseline

Results from connected devices, including audiometers and spirometers, land in the record and can be compared with the worker's own baseline and with reference standards such as OSHA.

Questionnaires before the visit

In the employee portal, workers answer questionnaires before a visit, upload documents and exchange messages with health professionals.

Overdue checks by site

Track health surveillance completion and results by site, country or company. Medical leaders and safety teams spot overdue checks without seeing personal medical details.

One record per worker, for decades

Employees and contractors keep the same health record across sites and rotations. Exposure history, exams and results stay together, so health professionals can compare recent results with earlier tests, even decades later.

Questions

Contact us
What is health surveillance software?
Software that runs a health surveillance program for each worker: who needs which exam, when it is due, how the results compare with earlier tests and what follow-up was decided. In MyC, surveillance is scheduled per worker from their exposure group, with due dates and expiry alerts, and the results stay in one health record per worker.
What is the difference between health surveillance and medical surveillance?
The terms overlap. In Great Britain, health surveillance is the umbrella term, and the Health and Safety Executive uses medical surveillance for a narrower case: exams by an HSE appointed doctor, which the law requires for certain hazards such as asbestos, lead and ionizing radiation. In the US, medical surveillance is the program of exams and tests that specific OSHA standards require employers to make available to workers exposed to certain hazards.
Do you track worker exposure?
Yes. Surveillance is scheduled per worker from their exposure group, with due dates and expiry alerts. Results from connected medical devices, including audiometers and spirometers, land straight into the record and can be compared against the worker's own baseline, so a shift in hearing or lung function shows at the next exam.
Which medical devices send results to MyC?
Audiometers (Amplivox, Tremetrics and FIM Medical), spirometers (ndd), vision screening devices (FIM Medical) and EKGs (Cardioline) send complete test results to the worker's health record. This reduces manual entry, and results can be compared across sites and over time.
Does MyC cover contractors as well as employees?
Yes. Contractors and employees use the same health record system, fitness-to-work rules and reporting. Their health surveillance history follows them between sites.
Who can see surveillance results?
Access is based on each person's role. Authorized health professionals work in the full medical record. Medical leaders and safety teams can track surveillance completion and overdue checks by site without personal medical details. Every access is logged.
