RESUMEN
INTRODUCTION: Old people attend emergency departments (ED´s) in increasing numbers. Old people have age related changes in all organ systems and tend to have multiple chronic diseases, be on multiple medications and often have physical and cognitive functional impairments. Hence, they have complex health and social service needs. The purpose of this study was to describe function and geriatric syndromes of old people who present at Landspitali Emergency Department, Iceland, with comparison to ED´s in six other countries. MATERIAL AND METHODS: A prospective descriptive study of people (>75 year´s) attending ED´s in seven countries, including Iceland. The InterRAI assessment tool for ED´s was used by nurses to assess participants. RESULTS: At Landspitali ED, 202 individuals were assessed, of whom 55% were women. Of the 202 individuals, 34% attended the ED within 90 days and of those 48% lived alone. On admission to the ED, 59% had physical or cognitive functional impairment; 13% had only cognitive impairment and 36% were unable to walk without assistance. Caregiver distress was identified in 28% and 11% felt overwhelming burden. From the ED, 46% were admitted to the hospital. Compared with foreign results greater number of Icelandic participants lived alone and caregiver's distress was slightly higher (28% vs. 18%). Fewer individuals in Iceland were admitted to a hospital and Iceland had higher admission rate to rehabilitation compared with the overall group. CONCLUSION: Geriatric syndromes and functional impairment afflicted majority of old people who attended the Landspitali ED. These observations should be taken into account in ED design and care planning for old people to maximize efficiency, safety and quality.

BACKGROUND: The prevalence and characteristics of airway obstruction in older individuals varies widely with the definition used. We used a random sample of never smoking older population in Iceland to compare the prevalence and clinical profile of subjects diagnosed with Chronic Obstructive Pulmonary Disease (COPD) based on different spirometric criteria. MATERIAL AND METHODS: The study uses data from the Age, Gene/Environment Susceptibility-Reykjavik Study, comprising survivors from the Reykjavik Study. Procedures included standardized questionnaires and pre-bronchodilator spirometry for measurement of forced expiratory volume in one second (FEV1) and forced vital capacity (FVC). RESULTS: Total of 495 individuals (150 men and 345 women) met study criteria. Mean age 77 years (range 66-92 years) using fixed ratio (FEV1/FVC < 70%) up to 29% of the population were diagnosed with COPD Stage I. The prevalence of COPD increased with age. Only 7 among 495 (1.4%) were diagnosed with COPD using FEV1/FVC LLN and FEV1 LLN. CONCLUSION: Application of the GOLD criteria for diagnosis of COPD in older lifelong never smoking subjects identifies a substantial number of non-symptomatic subjects as having COPD. If airway obstruction is defined by FEV1/FVC and FEV1 being below the LLN using appropriate reference equations, only very few non-smoking older individuals fulfill the criteria for COPD.

OBJECTIVE: To evaluate the efficacy of high frequency ventilation (HFV) in infants failing conventional ventilator therapy at our institution. STUDY GROUP AND METHODS: Medical records of all infants managed on HFV after having failed conventional ventilator management from 1994-2004 were reviewed. Ventilatory settings, blood gases and pH just prior to starting HFV, and two and four hours after starting HFV were recorded. RESULTS: Sixty one infants met the study criteria. At two hours of HFV there was a significant improvement in oxygenation (Alveolar to arterial oxygen tension difference), ventilation and acid-base balance. These values were not significantly different between two and four hours of HFV. There was no significant difference in oxygenation between survivors (n=41) and non-survivors (n=20) prior to HFV, but after two hours of HFV the survivors had significant improvement in oxygenation. Thirty one of the survivors had improved oxygenation at two and four hours of HFV, but only eight of the nonsurvivors (p=0.03). CONCLUSIONS: HFV results in significant improvements in oxygenation, ventilation and acid-base balance in most infants failing conventional ventilatory management. The immediate response to HFV may be a predictor of survival in infants with severe hypoxic respiratory failure.
