Global health metrics come into being in complex circumstances. Through ethnography that focuses closely on the forces driving uneven obstetric case reporting in a government hospital in northern Pakistan, this article challenges the integrity of the health care system documentation on which the state and non-state interventions and evaluations rely. Incomplete and skipped case records not only resulted from the time constraints posed by work on a busy maternity ward. They also helped vulnerable frontline providers disguise and avoid accountability for the aftermaths of the medical mismanagement and maltreatment made more likely by infrastructural scarcity and disarray. Yet the provider-side protections these tactics afforded came at patients' expense because they rendered error, wrongdoing, and iatrogenesis as invisible and unactionable. The sum of these reporting practices was "hospital paperworlds": defensively authored and aspirational datasets that conveyed desired rather than achieved outcomes, decontextualized risks and harms, and were too-rarely triangulated for their correlational significances or deficiencies.
