8 Doctors Face Disciplinary Action: What You Need to Know (2026)

In a recent development, the Rhode Island Department of Health has taken decisive action against eight licensed physicians, sanctioning them for various professional misconduct. This move underscores the department's commitment to maintaining high standards of medical practice and patient safety. The sanctions, which were made public on Wednesday, range from formal reprimands to more severe penalties, including the suspension of one doctor from practice in multiple states. This article delves into the details of each case, offering a critical analysis of the issues at hand and the broader implications for the medical community.

The Cases

1. Sita Singhal, D.O.

Dr. Singhal, a physician licensed in Rhode Island, Connecticut, and New York, has been suspended from practice in Connecticut and has agreed not to practice in Rhode Island or New York. This decision stems from concerns over her professional conduct, although specific details were not disclosed. The suspension highlights the importance of reciprocity in medical licensing, where actions in one state can have consequences in others.

2. Madalyn M. Nygren, M.D.

Dr. Nygren, licensed in Rhode Island since June 2024, faces a $1,100 penalty and a formal reprimand. The reprimand was issued following an investigation into her handling of a patient's care at Roger Williams Medical Center. The patient, who had undergone a Dilation and Curettage procedure, presented with vaginal bleeding and abdominal pain. Dr. Nygren was found to have failed to evaluate the patient adequately and to have neglected to provide patient information to providers at Women & Infants Hospital upon the patient's transfer. This case underscores the critical importance of comprehensive patient assessment and effective communication in emergency medicine.

3. Pedro Mariano Barros, M.D.

Dr. Barros, licensed in Rhode Island since 2003, received a reprimand and a $1,100 administrative fee. The reprimand was issued following an investigation into his prescription of metoclopramide for an extended period, despite published warnings about the medication's limitations. The investigation revealed that Dr. Barros had not adequately discussed the risks and potential side effects with the patient or monitored the patient for adverse conditions. This case serves as a reminder of the importance of adhering to evidence-based guidelines and maintaining open communication with patients.

4. Robert Shalvoy, M.D.

Dr. Shalvoy, a licensed orthopedic surgeon since 1990, faces a reprimand and a $1,100 penalty. The reprimand was issued following an investigation into his care of Patient A, who had been treated for bilateral knee pain. The investigation revealed that Dr. Shalvoy had failed to recognize the joint infection and had not sent cultures of joint aspirates for the August 14th and September 1 visits. This case highlights the critical importance of recognizing and treating complications promptly and accurately.

5. Marija Zhukov, M.D.

Dr. Zhukov, licensed in Rhode Island since 2011, received a reprimand and a $1,100 administrative fee. The reprimand was issued following an investigation into her administration of anesthesia to a patient prior to cataract and glaucoma surgery. The patient suffered a vitreous hemorrhage following the procedure, which was attributed to the patient's severe myopia, of which Dr. Zhukov was unaware. This case underscores the importance of thorough patient evaluation and the need for surgeons to communicate critical information to anesthesiologists.

6. Sumit Kumar Das, M.D.

Dr. Das, licensed in Rhode Island since 2000, faces a reprimand and a $1,100 penalty. The reprimand was issued following an investigation into his performance of a cervical facet injection, which resulted in the patient's cardiac arrest. The investigation revealed that Dr. Das had failed to follow necessary procedures to prevent local anesthetic systemic toxicity (LAST) and that his office lacked the appropriate emergency equipment. This case highlights the importance of adhering to safety protocols and ensuring that medical facilities are adequately equipped to handle emergencies.

7. Marc Taiwo Awobuluyi, M.D.

Dr. Awobuluyi, licensed in Rhode Island since 2007, received a reprimand and a $1,100 administrative fee. The reprimand was issued following an investigation into his handling of an X-ray report in Wisconsin. The investigation revealed that Dr. Awobuluyi had not reported his findings directly to the facility or the treating physician, instead faxing the report to the facility where a nurse received it and left the results with the answering service. This case underscores the importance of direct and timely communication in medical reporting.

8. William Thompson, M.D.

Dr. Thompson, who entered into a Consent Order in April 2025, has been in compliance with the terms. However, the order has been modified to terminate the requirement to maintain a treatment and monitoring contract with the Rhode Island Medical Society Physicians Health Program (PHP), as the PHP declined to enter into a contract due to the lack of a mental health diagnosis. Dr. Thompson has agreed to remain in therapy and provide reports to the Board every four months, as well as to undergo yearly polygraph tests.

Analysis and Commentary

These cases highlight a range of issues within the medical community, from communication breakdowns to adherence to safety protocols. Each case serves as a reminder of the critical importance of maintaining high standards of care and professionalism. The sanctions issued by the Rhode Island Department of Health send a clear message that misconduct will not be tolerated and that accountability is essential.

In my opinion, these cases underscore the need for continuous education and professional development within the medical community. Doctors must stay informed about the latest guidelines and best practices, and they must be vigilant in their commitment to patient safety. Additionally, medical facilities must ensure that they have the necessary equipment and protocols in place to handle emergencies effectively. The cases also highlight the importance of effective communication, both within medical teams and with patients, to ensure that everyone is on the same page and working towards the same goals.

Looking ahead, it is essential that medical professionals continue to strive for excellence in their practice. This includes staying up-to-date with the latest research and guidelines, as well as being open to feedback and constructive criticism. By doing so, we can ensure that the medical community remains a beacon of professionalism and patient-centered care, even in the face of challenges and setbacks.
