Hospital detention practices can be defined as refusal to release living patients after medical discharge is clinically indicated, or refusal to release bodies of deceased patients, when families are unable to pay hospital bills. Each additional day for which patients are detained adds to their bills, increasingly hindering families’ ability to obtain patients’ release. Patients are sometimes detained in hospitals, or bodies detained in mortuaries, for months. Occasionally, patients are completely left behind in hospitals when families are unable to pay. Unclaimed patients’ bodies might be disposed of in mass graves. The problem’s magnitude is unknown, but is probably more widespread than is documented. Hospital detention has been reported by human rights organisations, clinicians, journalists, and laypeople in Africa, Asia, Latin America, and eastern Europe. The problem aff ects children and adults with acute disorders (eg, people involved in road accidents and women with birth complications) and chronic diseases (eg, cancer or HIV/AIDS). Reports do not have consistent terminology to enable comparisons of studies worldwide or to eff ectively unite forces. We have formed the International Society of Paediatric Oncology and Paediatric Oncology in Developing Countries (SIOP PODC) Global Taskforce on Hospital Detention Practices, with the following objectives: to augment critical awareness; to introduce consistent terminology; to help to map global scope reliably; to elucidate adverse consequences; to address root causes; and to identify and support implementation of eff ective solutions to end hospital detention practices. The Taskforce endorses the following core statements related to each objective. Patients’ detention violates international human rights, including the right to not be imprisoned as a debtor and to have access to medical care. Recommended terminology includes “hospital detention practices” and “detained patients”. The term “detention” minimises confusion with positive health-care retention in medical literature. The term “practices” more accurately describes reality than does “policies”. Although hospital detention is often not the offi cial policy publicly defended by governments, it might be a wide spread unofficial practice. To map the global scope, the Taskforce calls on professionals and advocates to report hospital detention in scientifi c journals, media, and public venues. Recognition of adverse consequences is crucial. Fear of detention might prevent or delay conventional medical help-seeking, and encourages abandonment of potentially curative treatment after patients’ release. Progressive or relapsed disease and unnecessary death often result. Detention aggravates hospital overcrowding, increases infection risk, and denies schooling to children. Hospital detention is often the result of mismanagement, corruption, dysfunctional health-care system structures, inadequate health insurance coverage, and unfair waiver procedures, warranting attention. Advocacy by stakeholders is urgently needed (panel). Our Taskforce endorses this position statement in the conviction that detention of patients is unethical and inhumane, and must end.
