Healthcare-associated infections and antimicrobial use at a major referral hospital in Papua New Guinea: a point prevalence survey.

Background: Healthcare-associated infections (HAI) and antimicrobial use (AMU) are drivers for antimicrobial resistance, and robust data are required to inform interventions and track changes. We aimed to estimate the prevalence of HAI and AMU at Port Moresby General Hospital (PMGH), the largest hospital in Papua New Guinea. Methods: We did a point prevalence survey (PPS) on HAI and AMU at PMGH in May 2023 using the European Centre for Disease Prevention and Control (ECDC) PPS protocol. We included all critical care patients and randomly sampled half of the patients in other acute-care wards. We calculated weighted HAI and AMU prevalence estimates to account for this sampling strategy. Weighted HAI estimates were also calculated for an expanded definition that included physician diagnosis. Findings: Of 361 patients surveyed in 18 wards, the ECDC protocol identified 28 HAIs in 26 patients, resulting in a weighted HAI prevalence of 6.7% (95% CI: 4.6, 9.8). Surgical site infections (9/28, 32%) were the most common HAI. When adding physician diagnosis to the ECDC definitions, more skin and soft tissue, respiratory, and bloodstream HAIs were detected, and the weighted HAI prevalence was 12.4% (95% CI: 9.4, 16.3). The prevalence of AMU was 66.5% (95%CI: 61.3, 71.2), and 73.2% (263/359) of antibiotics were from the World Health Organization Access group. Interpretation: This is the first reported hospital PPS of HAI and AMU in Papua New Guinea. These results can be used to prioritise interventions, and as a baseline against which future point prevalence surveys can be compared.

Simplified management protocol for term neonates after prolonged rupture of membranes in a setting with high rates of neonatal sepsis and mortality: a quality improvement study.

In low-income and middle-income countries, courses of antibiotics are routinely given to term newborns whose mothers had prolonged rupture of membranes (PROM). Rational antibiotic use is vital given rising rates of antimicrobial resistance and potential adverse effects of antibiotic exposure in newborns. However missing cases of sepsis can be life-threatening.This is a quality improvement evaluation of a protocol for minimal or no antibiotics in term babies born after PROM in Papua New Guinea. Asymptomatic, term babies born to women with PROM >12 hours prior to birth were given a stat dose of antibiotics, or no antibiotics if the mother had received intrapartum antibiotics, reviewed and discharged at 48-72 hours with follow-up. Clinical signs of sepsis within the first week and the neonatal period were assessed. Of 170 newborns whose mothers had PROM, 133 were assessed at 7 days: signs of sepsis occurred in 10 babies (7.5%; 95% CI 4.4% to 13.2%) in the first week. Five had isolated fever, four had skin pustules and one had fever with periumbilical erythema. An additional four (3%) had any sign of sepsis between 8 and 28 days. There was one case of bacteraemia and no deaths. 37 were lost to follow-up, but hospital records did not identify any subsequent admissions for infection. A rate of sepsis was documented that was comparable with other studies in low-income countries. This protocol may reduce antimicrobial resistance and consequences of antibiotic exposure in newborns, provided safeguards are in place to monitor for signs of sepsis.

Three cases of neonatal tetanus in Papua New Guinea lead to development of national action plan for maternal and neonatal tetanus elimination.

Maternal or neonatal tetanus causes deaths primarily in Asia and Africa and is usually the result of poor hygiene during delivery. In 2011, three neonatal tetanus cases were investigated in Papua New Guinea, and all three cases were delivered at home by untrained assistants. The babies were normal at birth but subsequently developed spasms. A neonatal tetanus case must be viewed as a sentinel event indicating a failure of public health services including immunization, antenatal care and delivery care. The confirmation of these cases led to the drafting of the Papua New Guinea National Action Plan for Maternal and Neonatal Tetanus Elimination. This included three rounds of a tetanus toxoid supplementary immunization campaign targeting women of childbearing age (WBCA) and strengthening of other clean delivery practices. The first immunization round was conducted in April and May 2012, targeting 1.6 million WBCA and achieved coverage of 77%. The government of Papua New Guinea should ensure detailed investigation of all neonatal tetanus cases reported in the health information system and perform subprovincial analysis of tetanus toxoid coverage following completion of all three immunization rounds. Efforts also should be made to strengthen clean delivery practices to help eliminate maternal and neonatal tetanus in Papua New Guinea.
