The study was conducted to evaluate compliance of antibiotics prescribing in three selected outpatients healthcare facilities in Papua New Guinea(PNG), to the country specific Standard Treatment Guidelines(STG)and to identify factors influencing prescribing pattern. The study was carried out in the Losuia Health Centre (LHC), Alotau Provincial Hospital and Port Moresby General Hospital (PMGH) outpatient departments. The study sample involved300participants at each setting. Oral amoxicillin products, chloramphenicol and co-trimoxazole made up approximately 70% of the antibiotics prescribed to 637/1090 of patients. Almost one-quarter (24.4%) of prescriptions for antibiotics were non-compliant selections. At the LHC approximately 20% of both dosage and duration errors occurred. Overall non-compliant prescribing for children was approximately 50% but significantly more compliant at PMGH (P= 0.0058) contrasting with the other settings. At the LHC only 30.6% of antibiotic prescriptions for children were compliant with STG requirements and fulfilled PNG regulatory requirements. With respect to the STGs, Community Health Workers (68.0%) and Nurse Officers made more non-compliant antibiotic selections. High levels of antibiotic prescribing combined with high levels of non-compliant antibiotic prescribing as compared to PNG-STGs, were identified in this study. This is a disturbing finding as it raises many questions related to quality assurance of health care interventions in PNG. The data also raises a clinical concern for the high level of oral chloramphenicol prescribed in out-patient settings.

The USA has a high burden of childhood asthma. Previous studies have observed associations between higher blood lead levels and greater hypersensitivity in children. The objective of the present study was to estimate the association between blood lead concentrations during early childhood and an asthma diagnosis between 48 and 72 months of age amongst a cohort with well-characterized blood lead concentrations. Blood lead concentrations were measured at 6, 12, 18, 24, 36, and 48 months of age in 222 children. The presence of an asthma diagnosis between 48 and 72 months was assessed using a questionnaire which asked parents or guardians whether they had been told by a physician, in the past 12 months, that their child had asthma. Crude and adjusted risk ratios (RR) of an asthma diagnosis were estimated for several parameterizations of blood lead exposure including lifetime average (6 to 48 months) and infancy average (6 to 24 months) concentrations. After adjustment for child sex, birthweight, daycare attendance, maternal race, education, parity, breastfeeding, income, and household smoking, age-specific or composite measures of blood lead were not associated with asthma diagnosis by 72 months of age in this cohort.
