LEWISTON — Central Maine Healthcare continues to bring its communication systems back online amid a “system outage” as patients take to social media to air their struggles with reaching their providers in week four since the outage was announced June 1.

In an update Wednesday on the hospital system’s temporary website, the Cancer Care Center’s radiation equipment is back in operation. It is unclear if some patients were going without radiation while it was offline or being referred to other hospitals, and hospital officials did not respond to additional questions before publication.

“We are pleased to share that radiation therapy services at the Cancer Care Center have been fully restored,” states updated information on the website. “Our linear accelerators and related systems have undergone rigorous testing and validation by our information technology and oncology physics teams to ensure clinical readiness and patient safety.”

The oncology care team will be reaching out to patients soon to schedule or reschedule treatment appointments and discuss a care plan, according to the website.

In another update posted on the website Tuesday, the hospital system said it is calling patients to reconnect about routine appointments, lab and imaging results, and to reschedule elective surgeries. However it warned patients not to disclose certain information over the phone, such as Social Security numbers.

“Our team may ask you to confirm information, like your full name, date of birth, or insurance details,” the website states. “We will never ask for your Social Security number.”

If patients are unsure if the person calling them claiming to be from the hospital is legitimate, they should ask questions, hang up if it does not feel right and then call their doctor’s office directly or the hospital’s main switchboard, according to the website.

Most CMHC practices are now reachable by phone and the “Contact Us” form on the temporary website is being retired, according to information on the hospital’s website. The best way to reach providers directly is by phone or in person. For those unable to reach a provider or location using their normal phone number, call the hospital’s main switchboard.

To reach the systemwide switchboard and Central Maine Medical Center, call 207-795-0111. To reach the Bridgton Hospital’s main switchboard, call 207-647-6000. To reach Rumford Hospital’s main switchboard, call 207-369-1000.
