WASHINGTON — The U.S. Bureau of Prisons is facing renewed scrutiny over its handling of inmate grievances and access to medical care following the publication of analyses and reports that found many complaints are rejected on procedural grounds and that some prisoners have experienced lengthy delays in treatment.
An investigation published on Wednesday by NPR and The Marshall Project, based on federal prison grievance data, reported that the vast majority of inmate complaints do not result in relief and that many are dismissed for technical reasons before being reviewed on their merits. The findings have drawn attention from prisoner advocates, attorneys and former corrections officials who argue that the grievance process can hinder access to courts and medical care.
Under federal law, incarcerated individuals generally must complete the Bureau of Prisons' internal grievance process before pursuing legal action. According to the report, complaints are frequently rejected for procedural deficiencies, including filing errors and documentation issues. The report cited interviews with inmates, advocates and former officials, as well as federal records.
“The program is intended to solve problems and be responsive to issues raised by inmates,” Bureau of Prisons spokesperson Randilee Giamusso said in a statement cited by NPR. She added that the process “does not prevent inmates from pursuing litigation.”
The Bureau of Prisons disputed suggestions that grievances are routinely rejected for minor technicalities and said it is reviewing procedures and guidance related to complaint filings, according to the report.
The scrutiny comes amid broader concerns over healthcare delivery within federal prisons. In a 2025 report, the Justice Department's Office of the Inspector General found deficiencies in colorectal cancer screening and follow-up care for some inmates, citing cases in which recommended diagnostic procedures were delayed or not completed. The Bureau of Prisons said at the time it agreed with recommendations for improvement and attributed some shortcomings to longstanding staffing challenges. Officials said efforts were underway to strengthen screening and treatment programs.
Advocacy groups have also pointed to federal grievance records showing that only a small share of medical-care complaints result in relief, while many are denied or rejected during the administrative process. Those organizations argue that complex filing requirements can make it difficult for prisoners to pursue complaints involving healthcare, safety or prison conditions.
The Bureau of Prisons, which oversees more than 100 federal institutions nationwide, has said inmate grievance procedures are intended to provide a formal mechanism for resolving concerns and that prisoners may appeal adverse decisions through multiple levels of review.
As of Thursday, no major policy changes had been announced in response to the latest reporting. Bureau officials said they were continuing to review grievance procedures, while oversight bodies and advocacy organizations called for further examination of complaint handling and access to medical care within the federal prison system.
