As a client of 1 Source, we can help acquire the documentation & medical clearances needed to safely get your employee back on the job or to guide them on the right path needed, as required by a medical professional.

The employee can be set up for a follow-up clinic visit to be discharged from care. In this situation, 1 Source will speak with the clinic in advance and let them know of the employee’s wishes. There is also another option where the can sign a declination waiver, declining any further medical treatment.

There is no time frame set for number of follow ups calls an employee might have under the Access Care Program. The Access Care Program is a collaborative approach to providing first aid guidance for employees with minor injuries. Each employee is different in how they respond; therefore, each case is different. If the employee is continuing to improve and they feel comfortable with their first aid self-care guidance, they may continue under the Access Care Program. If they are not improving, getting worse or the Access Care Nurse feels they may need to be evaluated by a clinician, this will be communicated with the employee and the employer.

1 Source has an on-demand interpreter service that can be used with all of our services. When calling in to report an injury, notify 1 Source that an interpreter will be needed, and what language will be needed. The service has over 200 languages available.

1 Source offers 3 levels of first aid kits that have been carefully created to be used in conjunction with the Access Care Program. Please send a request to injurymgt@1source365.com  for more information regarding these kits.

Each company may have its own policies regarding injury care. 1 Source is mindful of those policies and prioritizes appropriate care based on best practices for the incident or injury being assessed. 1 Source will never force an employee to be seen at a clinic or follow up through the Access Care Program. We will make care recommendations that we feel are best for the employee’s wellbeing, again based on best practices. An employee has a right to refuse any medical treatment. If this is the case, the employee will be asked to sign a Medical Declination Waiver stating that they do not wish to seek any medical treatment at this time.

Access Care is the first tier of injury management. It allows 1 Source to manage an injury remotely, without the employee requiring a visit to a clinic. The injured employee will be put in direct contact with a practitioner or Nurse Case Manager who will evaluate the injury telephonically through tele-triage and develop the best plan of care using first aid treatments. The Access Care Program is available 24 / 7 / 365 and has proven to be an excellent resource for our client companies and their employees.

If it is determined that an employee requires medical care at a clinic, 1 Source will then transition to Case Management who will coordinate all aspects of the care, communication, and documentation. Each of the clinics in the network will interact directly with the 1 Source Nurse Case Manager so that we can properly manage the case to help ensure the best outcome. 

All initial injury calls will be placed through the dedicated injury line; (866) 622-7348. This number is accessible 24 / 7 / 365. This number can also be used for an existing injury when the employee’s condition worsens. All companies who are part of our injury program will always have access to a live injury management professional. Injury calls will be telephonically evaluated, and a care recommendation will be made based on this evaluation. All other calls should go through the regular office line, during regular business hours at (855) 517-6872.

All calls will go directly to a licensed medical professional who is trained in injury care and with exceptional knowledgeable of workers’ compensation. 

Yes, after each follow up call or office visit an injury summary report will generated in SourceLink and made electronically available to the designated company contact. If there is any significant change in the treatment plan, the main contact at the company will be notified with a phone call to discuss the case further.


The answer varies based on the company and protocol that is in place. Plan to spend anywhere between 1 ½ – 3 hours.
