Prior state
Carbapenem and last-line resistance in Gram-negative organisms was established in the named hospital systems at the origin and continued to spread. Antibiotic prophylaxis was an unexamined precondition of modern surgical and obstetric practice, and the risk calculations underlying elective procedures assumed it worked.
Material change
A defined set of common procedures — caesarean section, joint replacement, and the management of chemotherapy-associated neutropenia — carry materially higher infection mortality wherever empiric therapy fails routinely, and the institutional response is rationing and re-engineering rather than a new drug class. Reserve agents move to licensed allocation, payment is conditioned on infection metrics, elective volumes are cut in the highest-burden systems, and narrow-spectrum adjuncts including phage and monoclonal preparations enter practice with highly uneven availability.
Why now
The threshold that matters is institutional, not microbiological, and it is crossed when the failure rate of empiric therapy in national surveillance data reaches the level at which surgical services must formally change their protocols rather than absorb the losses. That point arrives in this decade in the highest-burden systems because resistance prevalence has been rising steadily and because the reserve agents introduced in the 2030s and 2040s have themselves been eroded by two decades of use.
Mechanism and resistance
Hospital-acquired-infection liability and payment conditionality are the levers, and they work by making infection a financial event for the institution rather than a clinical event for the patient. Resistance comes from surgeons whose volumes fall, from private hospitals whose business models depend on elective throughput, and from agricultural users of the same drug classes, whose consumption is politically protected in most jurisdictions.
Consequences
Maternal mortality rises in specific middle-income settings that had been improving for decades — a reversal within a domain that had been treated as a one-way ratchet — because caesarean rates in those settings are high and infection control is weakest exactly where volumes are greatest. Medical tourism reroutes toward systems with demonstrable infection metrics, which become a marketed and audited quantity. The poor lose access to elective surgery first, since rationing operates through waiting lists and referral in public systems and through price in private ones.
End state
Elective surgical and obstetric practice in the highest-burden systems operates under formal infection-risk rationing with licensed access to reserve agents, and infection-attributable mortality for the named procedures is materially higher than at the interval's start.
Observable test
National surveillance resistance rates for Gram-negative organisms; post-operative and post-caesarean infection mortality; elective surgical volumes; the existence of statutory licensing for reserve antimicrobials.
Disconfirming sign
New antimicrobial classes combined with rapid point-of-care diagnostics restore reliable empiric therapy, and infection-attributable mortality falls.
