An evaluation of the clinical assessments of under-five febrile children presenting to primary health facilities in rural Ghana.

BACKGROUND: The shift to test-based management of malaria represents an important departure from established practice under the Integrated Management of Childhood Illnesses (IMCI). The possibility of false results of tests for malaria and co-morbidity, however, make it important that guidelines in IMCI case assessment are still followed. METHODS AND FINDINGS: We conducted a cross-sectional observational study to evaluate current practices in IMCI-based assessment of febrile children in 10 health centres and 5 district hospitals, with follow up of a subset of children to determine day 7-10 post-treatment clinical outcome. Clinical consultation, examination and prescribing practices were recorded using a checklist by trained non-medical observers. The facility case management of 1,983 under-five years old febrile children was observed and 593 followed up at home on days 5-10. The mean number of tasks performed from the 11 tasks expected to be done by the IMCI guidelines was 6 (SD 1.6). More than 6 tasks were performed in only 35% of children and this varied substantially between health facilities (range 3-85%). All 11 tasks were performed in only 1% of children. The most commonly performed tasks were temperature measurement (91%) and weighing (88%). Respiratory rate was checked in only 4% of children presenting with cough or difficulty in breathing. The likelihood of performing "better than average number of tasks" (>6) was higher when the consultation was done by medical assistants than doctors (O.R. = 3.16, 1.02-9.20). The number of tasks performed during assessment did not, however, influence clinical outcome (O.R. = 1.02, 0.83-1.24). CONCLUSION: Facility-tailored interventions are needed to improve adherence to IMCI guidelines incorporating test-based management of malaria. Studies are needed to re-evaluate the continued validity of tasks defined in IMCI case assessment guidelines

Denotational, causal and operational determinism in event structures

Determinism is a theoretically and practically important concept in labelled transition systems and trees. We study its generalisation to event structures. It turns out that the result depends on what characterising property of tree determinism one sets out to generalise. We present three distinct notions of event structure determinism, and show that none of them shares all the pleasant properties of the one concept for trees.

Management of febrile children under five years in hospitals and health centres of rural Ghana.

BACKGROUND: The case management of febrile children in hospitals' and health centres' pre-roll out of the new WHO policy on parasitological diagnosis was assessed. The delivery of artemisinin combination therapy (ACT) at these two levels of the health system was compared. METHODS: Structured observations and exit interviews of 1,222 febrile children attending five hospitals and 861 attending ten health centres were conducted in six districts of the Brong Ahafo Region of Ghana. Effectiveness of delivery of case management of malaria was assessed. Proportions of children receiving ACT, anti-malarial monotherapy and antibiotics were described. Predictors of: a febrile child being given an ACT, a febrile child being given an antibiotic and of carers knowing how to correctly administer the ACT were assessed using logistic regression models stratified by hospitals and health centres. RESULTS: The system's effectiveness of delivering an ACT to febrile children diagnosed with malaria (parasitologically or clinically) was 31.4 and 42.4% in hospitals and health centres, respectively. The most ineffective process was that of ensuring that carers knew how to correctly administer the ACT. Overall 278 children who were not given an ACT were treated with anti-malarial monotherapy other than quinine. The majority of these children, 232/278 were given amodiaquine, 139 of these were children attending hospitals and 93 attending health centres. The cadre of health staff conducting consultation was a common predictor of the outcomes of interest. Presenting symptoms and examinations conducted were predictive of being given an ACT in hospitals and antibiotic in hospitals and health centres but not of being given an ACT in health centres. Treatment-seeking factors were predictive of being given an ACT if it was more than seven days since the fever began and an antibiotic in hospitals but not in health centres. CONCLUSION: Interventions to improve adherence to negative parasitological tests are needed, together with guidance on dispensing of antibiotics, but improving the education of carers on how to administer ACT will lead to the greatest immediate increase in the effectiveness of case management. Guidance is needed on implementation of the new test-based treatment for malaria policy in health facilities
