Background: Limited data exist on long-term survival of patients requiring admission to intensive care units (ICUs). The aim of this study was to investigate long-term survival of ICU patients in Iceland and assess changes over a 15-year period.Methods: Data were collected on age, gender, admission cause, length of stay, comorbidities, mechanical ventilation and survival of patients 18 years and older admitted to the ICUs in Landspitali during 2002-2016. Long-term survival of patients surviving more than 30 days from admission was estimated and its predictors assessed with Cox regression analysis. Long-term survival was compared to the survival of an age-and gender-matched reference group from the general population. Results:Of 15 832 ICU admissions, 55% was medical, 38% was surgical and 7% was due to trauma. The 5-year survival of medical, surgical and trauma patients was 66%, 76% and 92% respectively. Significant survival differences were found between admission subgroups. Higher age and comorbidity burden was related to decreased survival in all patient groups. After correcting for age, gender, comorbidities, length of ICU stay and mechanical ventilation, patient survival improved during the study period only for patients admitted for infections. There was a high variability in the estimated time point where the ICU admission had no residual effect on survival.Conclusions: Long-term survival of ICU patients is substantially decreased compared to the general population, but varies based on admission causes. Improved long-term survival of patients admitted with infections could be explained by earlier detection and improved treatment of septic shock.
Spontaneous subarachnoid haemorrhage is characterized by extravasation of blood into the subarachnoid space without a preceding trauma. The leading cause is a ruptured intracranial aneurysm. Serious neurologic complications can occur, such as rebleeding, cerebral vasospasm and delayed cerebral ischemia. Subarachnoid haemorrhage is a serious condition with a high mortality rate and those who survive often suffer long-term consequences. Prevention of rebleeding by aneurysm repair is essential and guidelines recommend this procedure should be done as soon as possible or within 72 hours. Management requires intensive care with emphasis on accurate blood pressure control, maintaining normal fluid and electrolyte balance and monitoring the level of consciousness. All patients should be treated with the calcium channel blocker nimodipine to reduce the risk of vasospasm and delayed cerebral ischemia which are among the most serious complications of subarachnoid haemorrhage.
Background Tracheostomies are commonly utilized in ICU patients due to prolonged mechanical ventilation, upper airway obstruction, or surgery in the face/neck region. However, practices regarding the timing of placement and utilization vary. This study provides a nationwide overview of tracheostomy utilization and outcomes in the ICU over a 14‐year period. Methods A retrospective study including all patients that received a tracheostomy during their ICU stay in Iceland between 2007 and 2020. Data were retrieved from hospital records on admission cause, comorbidities, indication for tracheostomy insertion, duration of mechanical ventilation before and after tracheostomy placement, extubation attempts, complications, length of ICU and hospital stay and survival. Descriptive statistics were provided, and survival analysis was performed using Cox regression. Results A total of 336 patients (median age 64 years, 33% females) received a tracheostomy during the study period. The most common indication for tracheostomy insertion was respiratory failure, followed by neurological disorders. The median duration of mechanical ventilation prior to tracheostomy insertion was 9 days and at least one extubation had been attempted in 35% of the cases. Percutaneous tracheostomies were 32%. The overall rate of complications was 25% and the most common short‐term complication was bleeding (5%). In‐hospital mortality was 33%. The one‐ and five‐year survival rate was 60% and 44%, respectively. Conclusions We describe a whole‐nation practice of tracheostomies. A notable finding is the relatively low rate of extubation attempts prior to tracheostomy insertion. Future work should focus on standardization of assessing the need for tracheostomy and the role of extubation attempts prior to tracheostomy placement.
