Peripheral paediatric clinics: survey and medical audit.

The work of the paediatric clinics in nine general-practitioner hospitals in country towns in the Bath Health District during 1972 was analysed with respect to the pattern of referrals and methods of management. It is concluded that no child suffered harm from being seen in a clinic without full laboratory and x-ray facilities. Nearly 98% of the consultations were deemed, even with a long period of hindsight, to have been completely satisfactory. The tremendous benefit to the patients and their families of being seen in a hospital near their home is not bought at the cost of a second-rate medical service.     

Trends in use of medical services by the elderly in British Columbia.

We analysed physician fee-for-service use in British Columbia from 1974-75 to 1985-86. Over the study period use increased by 5.3% per year. This can be factored into increases attributable to changes in the age structure of the population (0.4% per year), general population growth (1.8%, for a combined annual "population effect" of 2.2%) and age-specific increases in per-capita use (3% per year). The average annual increase for people aged 75 years or more was 5.5% per capita. The area with the fastest growth in use by the elderly was specialist care, particularly diagnostic services. The average number of specialists seen by people aged 75 years or more doubled over the study period. Our results suggest that increased per-capita use among the elderly that is unrelated to aging of the population should be the main focus of future policy attention. Additional analyses are needed to determine the underlying dynamics of this dramatic increase in rates of use among the elderly.     

Trends in paediatric and adult bloodstream infections at a Ghanaian referral hospital: a retrospective study

Background

Bloodstream infections (BSI) are life-threatening emergencies. Identification of the common pathogens and their susceptibility patterns is necessary for timely empirical intervention.

Methods

We conducted a 4-year retrospective analysis of blood cultures from all patients excluding neonates at the Korle-Bu Teaching hospital, Ghana, from January 2010 through December 2013. Laboratory report data were used to determine BSI, blood culture contamination, pathogen profile, and antimicrobial resistance patterns.

Results

Overall, 3633 (23.16 %) out of 15,683 blood cultures were positive for various organisms. Pathogen-positive cultures accounted for 1451 (9.3 %, 95 % CI 8.5–9.8 %). Infants recorded the highest true blood culture positivity (20.9 %, n = 226/1083), followed by the elderly (13.3 %, n = 80/601), children (8.9 %, n = 708/8000) and adults (7.2 %, n = 437/6000) (p = 0.001 for Marascuilo’s post hoc). Overall occurrence of BSI declined with increasing age-group (p = 0.001) but the type of isolates did not vary with age except for Citrobacter, Escherichia coli, Klebsiella, Salmonella, and Enterococcus species. Gram negative bacteria predominated in our study (59.8 %, n = 867/1451), but the commonest bacterial isolate was Staphylococcus aureus (21.9 %, n = 318/1451)—and this trend run through the various age-groups. From 2010 to 2013, we observed a significant trend of yearly increase in the frequency of BSI caused by cephalosporin-resistant enterobacteria (Chi square for trend, p = 0.001). Meropenem maintained high susceptibility among all Gram-negative organisms ranging from 96 to 100 %. Among Staphylococcus aureus, susceptibility to cloxacillin was 76.6 %.

Conclusion

Our study shows a significantly high blood culture positivity in infants as compared to children, adults and the elderly. There was a preponderance of S. aureus and Gram-negative bacteria across all age-groups. Meropenem was the most active antibiotic for Gram-negative bacteria. Cloxacillin remains a very useful anti-staphylococcal agent.
