- Desenvolvimento de um sistema multidimensional para classificação e gestão de informação em saúde: aplicabilidade à informação clínicaPublication . Rama, AC; Isabel, O; Silva, CM; Fernandez-Llimos, F; Figueiredo, IV; Caramona, MINTRODUCTION: The large amount of information in the medical area creates management problems, being necessary systematic methods for filing and retrieval. With information on the context of clinical records, methods must integrate controlled biomedical terminologies and desirable characteristics oriented to the structure, content and clinical results. The objective is to test the applicability and capacity for retrieval of a multidimensional system developed for classification and management of health information. METHODS: Three hundred questions were randomly selected, by computerized method, from the questions received in six years (Medicine Information Service, Pharmaceutical Department, Coimbra University Hospitals). They were characterized and applicability evaluated by classified amount and need to alter the system, which is composed of various independent dimensions, incorporating concepts sometimes hierarchical. Questions retrieval was tested searching information in a dimension or between dimensions. RESULTS: All questions were classified: 53% are clinical cases with illnesses incidence in the genitourinary system; metabolic, nutritional and endocrine disease; cancer; infections and nervous system. In 81%, the object is a drug, mostly anti-infectious and anti-neoplastic agents. The therapeutic and safety areas had been the most requested, regarding the subjects: use, adverse reactions, drug identification and pharmaceutical technology. As to applicability, it was necessary to add some concepts and modify same hierarchical groups, that didn't modify the basic structure, nor had collided with the desirable characteristics. The limitations were related with the incorporated external classification systems. The search in the subject dimension of the concept drug administration retrieved 19 questions. The search between two dimensions: antiinfectious (external) and teratogenicity (subject) retrieved three questions. In the two examples, it was possible to retrieve information from any one of the levels of the hierarchy, from the most general to the most specific and even from external dimensions. CONCLUSIONS: The use of the system in this sample showed its applicability in clinical information classification and filing, retrieval capacity and flexibility, supporting modifications without interfering with desirable characteristics. This tool allows retrieval of patient-oriented evidence that matters.

- Recém-nascidos e monitorização sérica de gentamicinaPublication . Rocha, MJ; Almeida, MM; Afonso, E; Martins, V; Leitão, F; Santos, J; Falcão, ACNewborn infants in intensive care units demonstrated a higher incidence of gestational age below 31 week. Obstetrical and neonatal diseases procedures required for the management of critically ill neonates are associated with an increased risk of infections. Gentamicin is an aminoglycoside antibiotic often used to treat gram-negative bacillary infections and suspected sepsis in neonates. The risk of toxicity or poor efficacy is further increased due to the recognised wide intra and interpatient variability of the newborn. The present work involved 49 infants of 31.3 +/- 4.1 (mean +/- SD) weeks of gestational age, weighing 1.7 +/- 0.8 kg and were treated with standard doses of gentamicin (3.8 +/- 0.9 mg/kg/day). Routine clinical care data were retrospectively collected from the medical records in the neonatal intensive-care unit at Coimbra University Hospital. Data analysis demonstrated that potentially toxic serum levels were observed in 49% of newborn infants (trough > 2 mg/L). Additionally, the obtained results also showed that 7.5% of peak concentrations were found to be higher than 10 mg/L. Potentially sub-therapeutic concentrations were observed in 15% of the patients (peak > 6 mg/L).
