- ItemFactores pronósticos, evolución y mortalidad en el adulto inmunocompetente hospitalizado por neumonía neumocócica adquirida en la comunidad(2009) Saldías Peñafiel, Fernando; Viviani García, Paola; Pulgar B., Dahiana; Valenzuela Flores, Francisco Felipe; Paredes Engber, Sebastián; Díaz Patiño, OrlandoBackground: Streptococcus pneumoniae is the main cause of community-acquired pneumonia in adults. Aim: To describe baseline characteristics, risk factors and clinical outcomes of adult patients hospitalized with pneumococcal pneumonia. Material and methods: Prospective study of adult patients admitted for a community acquired pneumonia in a clinical hospital. Immune deficient patients and those with a history of a recent hospitalization were excluded. Results: One hundred fifty one immuno-competent patients, aged 16 to 92 years, 58% males, were studied. Seventy-five percent had other diseases, 26% were admitted to the intensive care unit and 9% needed mechanical ventilation. There were no differences in clinical features, ICU admission or hospital length of stay among bacteremic and non-bacteremic patients. Thirty days lethality for bacteremic and non-bacteremic patients was 10.9% and 11.5%, respectively. The predictive values for lethality of Fine pneumonia severity index and CURB-65 (Confusion, Urea nitrogen, Respiratory rate, Blood pressure, 65 years of age and older) had an area under the ROC curve of 0.8 and 0.69, respectively. Multivariate analysis disclosed blood urea nitrogen over 30 mg/ dL (odds ratio (OR), 6.8), need for mechanical ventilation (OR, 7.4) and diastolic blood pressure below 50 mmHg (OR, 3.9), as significant independent predictors of death. Conclusions: Pneumococcal pneumonia was associated with a substantial rate of complications and mortality. Clinical presentation and outcome did not differ significantly among patients with and without bacteremia.

- ItemManejo de la neumonía comunitaria del adulto mayor en el ámbito ambulatorio(2006) Moore Clive, Philippa Mary; Ortega, Juan Pablo; Saldías Peñafiel, Fernando; Oyarzún Andrade, María AngélicaCommunity Acquired Pneumonia (CAP) is the first cause of death by respiratory disease in Chile and the first specific cause of death in people over 80 years of age. The geriatric population has a greater risk of suffering pneumonia, its complications and consequently dying. This is not only related to chronological age but also to certain factors related to ageing such as the presence of comorbidity, malnutrition, and cognitive impairment. An atypical presentation that delays the diagnosis and treatment also increases the risk of complications. CAP in the elderly is caused by the same pathogens that cause it in younger patients. S pneumoniae is the main pathogen followed by viral infections particularly in winter. An important strategy to reduce CAP related health costs, is the identification of patients who are at low risk of complications and who therefore could be managed at home. Optimum management of CAP in the elderly includes early diagnosis and the definition of clinical severity, early antibiotic treatment at the tight dose and for an adequate length of time and a correct decision whether the patient should be managed in hospital or at home.

- ItemMetodología de adaptación de una guía clínica para el manejo de pacientes adultos con neumonía adquirida en la comunidad en una red de salud privada(2011) Pantoja Calderón, Tomás; Ferdinand Olivares, Constanza; Saldías Peñafiel, Fernando; Rojas Orellana, Luis; Balcells Marty, María Elvira; Castro López, Ricardo; Poblete Umanzor, Rodrigo EduardoBackground: Clinical practice guidelines (CPG) are widely used as tools for improving quality of health care. Guidelines developed elsewhere, can be adapted using a valid and systematic process. Aim: To describe the methodology used in the process of adaptation of a guideline for the management of adults with community-acquired pneumonia (CAP) in a private health care organization. Material and Methods: We used the ADAPTE framework involving three main phases. At the set-up phase a guideline adaptation group integrated by medical specialists from different disciplines, a methodologist and a nurse coordinator was formed. At the adaptation phase, the specific clinical questions to be addressed by the guidelines were identified. Results: Twenty five guidelines were initially retrieved. After their assessment, the number was reduced to only three. Recommendations from these guidelines were 'mapped' and focused searches were carried out where 'evidence gaps' were identified. An initial draft was written and revised by the adaptation group. At the finalization phase, the external review of the guideline was carried out and a process for the regular review and update of the adapted guideline was defined. Conclusions: We developed a guideline for the management of adults with CAP, adapted to the local context of our health care system, using guidelines developed elsewhere. This guideline creation method can be an efficient means of saving professional resources.
- ItemNeumonía adquirida en la comunidad en el adulto hospitalizado. Cuadro clínico y factores pronósticos(2002) Saldías Peñafiel, Fernando; Mardónez Urrutia, José Miguel; Marchesse Rolle, Miguel Ángel; Viviani García, Paola; Farías G, Gonzalo; Díaz Fuenzalida, AlejandroBackground: Community-acquired pneumonia (CAP) is a serious health problem in Chile. Aim: To study prognostic factors on admission and outcome of CAP, in immune competent adult patients, hospitalized in the Catholic University Clinical Hospital. Patients and methods: All adult patients admitted with a CAP in a period of 2 years were prospectively studied. Patients with immunodeficiency, solid tumors or receiving oral adrenal steroids were excluded from the study. Results: In the study period, 463 patients (69±19 years, 55% male) were evaluated. Ninety four percent were treated with 2nd or 3rd generation cephalosporins. Mean hospital length of stay was 10 days. Mortality during hospital stay was 8% and in the ensuing 30 days, it was 12%. Bacterial etiology was established in 25% of cases. The most frequent pathogens isolated were Streptococcus pneumoniae (10.2%), Haemophilus influenzae (3.7%), Staphylococcus aureus (2.8%) and Gram negative bacilli (5.2%). Admission prognostic factors associated with hospital mortality were: an age over 65 years, presence of comorbidity, chronic neurological and hepatic disease, suspicion of aspiration, duration of symptoms for less than 3 days, presence of dyspnea and altered mental status, absence of cough, fever and chills; low blood pressure, tachypnea, metabolic acidosis, hypoxemia, high blood urea nitrogen, hypernatremia, hyperkalemia, hyperphosphatemia, hypoalbuminemia, multilobar radiographic pulmonary infiltrates, bacteremia, high risk categories of the Fine Index (IV and V), and admission to Intermediate Care Unit or ICU. Conclusions: The features of community acquired pneumonia of these patients are similar to those reported abroad.
