Unresponsive Low Mixed Venous Oxygen Saturation During Early Intensive Care Unit Stay is Associated With Increased Risk of Organ Dysfunction After Cardiac Surgery: A Single-Center Retrospective Study.

OBJECTIVES: The aim of the study was to determine if unresponsive mixed venous oxygen saturation (SvO2) values during early postoperative hours are associated with postoperative organ dysfunction. DESIGN: A single-center retrospective observational study. SETTING: A university hospital. PARTICIPANTS: A total of 6,282 adult patients requiring cardiac surgery who underwent surgery in a University Hospital from 2007 to 2020. INTERVENTIONS: A pulmonary artery catheter was used to gather SvO2 samples after surgery at admission to the intensive care unit (ICU) and 4 hours later. For the analysis, patients were divided into 4 groups according to their SvO2 values. The rate of organ dysfunctions categorized according to the SOFA score was then studied among these subgroups. MEASUREMENTS AND MAIN RESULTS: The crude mortality rate for the cohort at 1 year was 4.3%. Multiple organ dysfunction syndrome (MODS) was present in 33.0% of patients in the early postoperative phase. During the 4-hour initial treatment period, 43% of the 931 patients with low SvO2 on admission responded to goal-directed therapy to increase SvO2 >60%; whereas, in 57% of the 931 patients, the low SvO2 was sustained. According to the adjusted logistic regression analyses, the odds ratio for MODS (4.23 [95% CI 3.41-5.25]), renal- replacement therapy (4.97 [95% CI 3.28-7.52]), time on a ventilator (2.34 [95% CI 2.17-2.52]), and vasoactive-inotropic score >30 (3.62 [95% CI 2.96-4.43]) were the highest in the group with sustained low SvO2. CONCLUSIONS: Patients with SvO2 <60% at ICU admission and 4 hours later had the greatest risk of postoperative MODS. Responsiveness to a goal-directed therapy protocol targeting maintaining or increasing SvO2 ≥60% at and after ICU admission may be beneficial.

Association of low mixed venous oxygen saturations during early ICU stay with increased 30-day and 1-year mortality after cardiac surgery: a single-center retrospective study.

BACKGROUND: Low postoperative mixed venous oxygen saturation (SvO2) values have been linked to poor outcomes after cardiac surgery. The present study was designed to assess whether SvO2 values of < 60% at intensive care unit (ICU) admission and 4 h after admission are associated with increased mortality after cardiac surgery. METHODS: During the years 2007-2020, 7046 patients (74.4% male; median age, 68 years [interquartile range, 60-74]) underwent cardiac surgery at an academic medical center in Finland. All patients were monitored with a pulmonary artery catheter. SvO2 values were obtained at ICU admission and 4 h later. Patients were divided into four groups for analyses: SvO2 ≥ 60% at ICU admission and 4 h later; SvO2 ≥ 60% at admission but < 60% at 4 h; SvO2 < 60% at admission but ≥ 60% at 4 h; and SvO2 < 60% at both ICU admission and 4 h later. Kaplan-Meier survival curves, Cox regression models, and receiver operating characteristic curve analysis were used to assess differences among groups in 30-day and 1-year mortality. RESULTS: In the overall cohort, 52.9% underwent coronary artery bypass grafting (CABG), 29.1% valvular surgery, 12.1% combined CABG and valvular procedures, 3.5% surgery of the ascending aorta or aortic dissection, and 2.4% other cardiac surgery. The 1-year crude mortality was 4.3%. The best outcomes were associated with SvO2 ≥ 60% at both ICU admission and 4 h later. Hazard ratios for 1-year mortality were highest among patients with SvO2 < 60% at both ICU admission and 4 h later, regardless of surgical subgroup. CONCLUSION: SvO2 values < 60% at ICU admission and 4 h after admission are associated with increased 30-day and 1-year mortality after cardiac surgery. Goal-directed therapy protocols targeting SvO2 ≥ 60% may be beneficial. Prospective studies are needed to confirm these observational findings.

Accuracy, Precision, and Trending Ability of Perioperative Central Venous Oxygen Saturation Compared to Mixed Venous Oxygen Saturation in Unselected Cardiac Surgical Patients.

OBJECTIVE: To determine whether central venous oxygen saturation (ScvO2) measurements could be used interchangeably with mixed venous oxygen saturation (SvO2) measurements in adult cardiac surgery patients. DESIGN: A single-center prospective observational study. SETTING: A university hospital. PARTICIPANTS: Eighty-five adult patients undergoing cardiac surgery. INTERVENTIONS: The study authors compared the oxygen saturations in 590 pairs of venous blood samples drawn from the pulmonary artery catheter (PAC) at three different time points during surgery and four different time points in the intensive care unit. They compared samples obtained from the distal pulmonary artery line (SvO2) to those drawn from the proximal central venous line of the PAC (ScvO2) with the Bland-Altman test and the four-quadrant method. MEASUREMENTS AND MAIN RESULTS: The mean bias between SvO2 and ScvO2 was -1.9 (95% confidence interval [CI], -2.3 to -1.5) and the limits of agreement (LOA) were -11.5 to 7.6 (95% CI, -12.5 to -10.7 and 6.8-8.5, respectively). The percentage error (PE) was 13.2%. Based on the four-quadrant plot, only 50% of the measurement pairs were in agreement, indicating deficient trending ability. CONCLUSION: ScvO2 values showed acceptable accuracy as the mean bias was low. The precision was inadequate; although the PE was acceptable, the LOA were wide. Trending ability was inadequate. The authors cannot recommend the use of ScvO2 values interchangeably with SvO2 measurements in the management of adult cardiac surgery patients.

Difference in postoperative opioid consumption after spinal versus general anaesthesia for ankle fracture surgery-A retrospective cohort study.

BACKGROUND: Surgical treatment of ankle fracture is associated with significant pain and high postoperative opioid consumption. The anaesthesia method may affect early postoperative pain. The main objective of the study was to compare postoperative opioid consumption after ankle-fracture surgery between patients treated with spinal anaesthesia and general anaesthesia. METHODS: We reviewed retrospectively the files of 586 adult patients with surgically treated ankle fracture in the years 2014 through 2016. The primary outcome was opioid consumption during the first 48 postoperative hours. Secondary outcomes were maximal pain scores, postoperative nausea and vomiting, the length of stay in the post-anaesthesia care unit, and opioid use in different time periods up to 48 h postoperatively. Propensity score matching was used to mitigate confounding variables. RESULTS: Total opioid consumption 48 h postoperatively was significantly lower after spinal anaesthesia (propensity score-matched population: effect size -13.7 milligrams; 95% CI -18.8 to -8.5; P < .001). The highest pain score on the numerical rating scale in the post-anaesthesia care unit was significantly higher after general anaesthesia (propensity score-matched population: effect size 3.7 points; 95% CI 3.2-4.2; P < .001). A total of 60 patients had postoperative nausea and vomiting in the post-anaesthesia care unit, 53 (88.3%) of whom had general anaesthesia (P = .001). CONCLUSIONS: Patients with surgically treated ankle fracture whose operation was performed under general anaesthesia used significantly more opioids in the first 48 h postoperatively, predominantly in the post-anaesthesia care unit, compared with patients given spinal anaesthesia.

Perioperative Risk Factors for One-Year Mortality in Patients With Free-Flap Reconstruction Due to Cancer of the Head and Neck.

PURPOSE: Head and neck cancer requiring free-flap reconstruction is associated with relatively high mortality. We aimed to evaluate perioperative risk factors for 1-year mortality in this patient group. METHODS: This is a single-center retrospective analysis of 204 patients operated during 2008 to 2018. RESULTS: A total of 47 (23.0%) patients died within 1 year. In univariate analysis, there were no differences in the intraoperative course between 1-year survivors and nonsurvivors. Among the 1-year nonsurvivors, preoperative albumin level was lower (39 [36 to 43] vs 42 [39 to 44], P = .032) and the Sequential Organ Failure Assessment admission score was higher (4 [3 to 5] vs 3 [2 to 4], P = .003) than those of the 1-year survivors. Among the nonsurvivors, the preoperative and postoperative levels of leukocytes were higher (7.6 [6.7 to 9.5] vs 6.9 [5.5 to 8.4], P = .002; 11.4 [9.0 to 14.2] vs 8.7 [7.2 to 11.3], P < .001). The highest odds ratios for 1-year mortality in multivariate analysis were American Society of Anesthesiologists A classification greater than 2 (3.9 CI 1.4 to 10.5), male gender (4.0 CI 1.5 to 11), and increase in leukocyte count (1.3 CI 1.1 to 1.5). CONCLUSIONS: One-year nonsurvivors had higher American Society of Anesthesiologists classification and were more often men. The postoperative inflammatory markers were higher in nonsurvivors, while the intraoperative course did not have a significant impact on the 1-year mortality.

Treatment Profile and 1-Year Mortality Among Nontraumatic Intensive Care Unit Patients With Alcohol-Related Health Problems.

BACKGROUND: Long-term excessive use of alcohol leads to severe complications, which often require treatment in an intensive care unit (ICU). The aim of this study was to report on the associations between alcohol-related health problems and treatment profile, as well as 1-year mortality among patients with nontrauma-related ICU admissions. METHODS: Information on the history of alcohol-related health problems or excessive alcohol use and ICU treatment was collected retrospectively from electronic medical records and ICU patient data management systems at Oulu University Hospital, Finland. Information on 1-year mortality was obtained from the Finnish Population Register Center. RESULTS: According to the medical records, in a total of 899 admissions, 32.9% (n = 296) of patients had a history of alcohol-related problems. In the alcohol group, intoxications were more frequent and respiratory and cardiovascular causes were less frequent, compared to those without alcohol-related problems. Patients without alcohol-related problems had a higher rate of previous comorbidities compared with the alcohol group. There were no differences concerning age, severity of illness scores, length of stay, or intensive care outcome. Mortality during the 1-year follow-up was 32.8% in total: 35.1% among those without alcohol-related history and 28.0% in the alcohol group (P = .041). The difference in mortality appeared during the first month following admission and remained throughout the follow-up period. The highest 1-year mortality (59.3%) was observed among patients with alcohol-related liver disease. CONCLUSION: Every third patient admitted to ICU used alcohol excessively or had alcohol-related diseases, and those patients with alcohol-related liver disease had the poorest 1-year survival rate. We found higher long-term mortality in nonalcohol-related admissions, which can be explained by the case mix, including a lower rate of chronic diseases, such as malignancies and coronary artery disease, and a higher rate of low-risk admission diagnoses in the alcohol group.

School Performance After Pediatric Intensive Care-Association of Mental Well-Being, Chronic Illnesses, and Family Socioeconomic Status.

OBJECTIVES: To describe school performance in pediatric intensive care survivors, as well as the influence of chronic diseases, psychological well-being, and family socioeconomic status on poor school performance. DESIGN: Register-based observational descriptive follow-up study. SETTING: A multicenter national study. PATIENTS: All pediatric patients who were admitted to an ICU in Finland in 2009-2010. Children and adolescents of or beyond school age. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Questionnaires regarding the child's coping in school classes, chronic illnesses, as well as family socioeconomic factors were sent to every child alive 6 years after discharge from intensive care in Finland. Mental well-being was measured with the Strengths and Difficulties Questionnaire. There were 1,109 responders in an ICU group of 3,674 children. Seven-hundred fifty-three of the respondents were of school age or older. Of these, 13% (101/753) demonstrated poor school performance. Children with difficulties in school more often had a need for regular medication (71.3% vs 32.4%; p < 0.001), healthcare visits (91.1% vs 80.6%; p = 0.01), some regular therapy (60.4% vs 13.7%; p < 0.001), chronic illnesses (86.3% vs 48.4%; p < 0.001), or additional ICU admissions (36.5% vs 14.9%; p = 0.003). Schooling difficulties were reported more often in children with abnormal Strengths and Difficulties Questionnaire scores compared to those with normal or borderline scores (24.8% vs 5.4%; p < 0.001). In an adjusted logistic regression model, which included age, number of chronic diseases, and need for therapy, poor school performance was predicted by abnormal Strengths and Difficulties Questionnaire scores, nonacademic parental education, and paternal manual labor status. CONCLUSIONS: Difficulties in school were more frequent when the child had chronic comorbid illnesses, especially neurologic or chromosomal abnormalities, had poor mental health, father was employed in manual labor, or parents were uneducated.

How does socioeconomic status affect the incidence of hospital-treated poisonings? A retrospective study.

BACKGROUND: Hospital-treated poisonings have a good outcome in general. The role of regional differences and socioeconomic status has been established in intensive care admissions and various causes of death, but not yet in hospital-treated poisonings. We set out to determine whether the incidence of hospital-treated poisonings is affected by the annual income of the residential area. METHODS: All poisonings in Northern Ostrobothnia region of Finland treated in Oulu University Hospital during 2013-2016 were studied. Oulu University Hospital is the primary hospital in the area. Postal code areas of the county were categorized on the basis of their median annual net income as low-, middle- and high-income areas. RESULTS: A total of 2142 poisoning cases were studied. The number of individual patients was 1525. In the low-income areas, the crude incidence of poisonings was more than 2-fold when compared with the middle- and high-income areas. In adolescents aged 13 to 17 years, the incidence in the low-income areas was almost 3-fold compared with the other two categories at 335/100 000/year (95% CI, 236-463). Four patients (0.2%) died during the hospital stay and 50 patients (2.3%) died within 6 months from the last admission. CONCLUSIONS: The incidence of hospital-treated poisoning was at least 2-fold in low-income areas when compared with middle- or high-income areas. For adolescent population from 13 to 17 years, the incidence in low-income areas was almost 3-fold when compared with other areas.

Long-term Outcome and Causes of Death for Working-age Patients Hospitalized Due to Acute Pancreatitis With a Median Follow-up of 10 Years.

OBJECTIVE: To examine long-term survival and causes of death among working-age patients with acute pancreatitis (AP) compared with the normal population. SUMMARY OF BACKGROUND DATA: Few studies have investigated long-term survival after AP and recurrent AP compared with the normal population; moreover, results from those studies are difficult to compare, due to suboptimal control populations and wide variations in follow-up times. METHODS: This retrospective, registry-based study included 1644 patients with AP, aged 18 to 64 years, admitted to Oulu University Hospital in 1995 to 2012. Patient data were compared with data from 8220 age- and sex-matched controls that resided in the hospital district area. RESULTS: Alcohol was the main etiologic factor causing 71.4% of the cases. During the median follow-up time of 9.5 years, mortality was 24.2% in the study group and 6.3% in the control group (P < 0.001). Alcohol-related factors caused 39.4% of deaths and alcohol AP was the main single cause of death (16.3%) in the study group. Of all fatal AP cases, 42.9% were related to recurrence. Survival was similar among patients with nonalcohol AP and controls. CONCLUSION: The long-term mortality among patients admitted to the hospital due to (mainly alcohol induced) AP was 4 times higher than that in the age- and sex-matched control population. The significant difference in the causes of death between patients with alcohol AP and controls could be explained by alcohol-related diseases. Occurrences of AP without an alcohol etiology had a minimal impact on survival.

Prophylactic pancreatic duct stenting in severe acute necrotizing pancreatitis: a prospective randomized study.

BACKGROUND: Pancreatic duct disruption is common and is associated with high morbidity in cases of acute necrotizing pancreatitis (ANP). In this study, we tested the feasibility and safety of prophylactic pancreatic duct stenting (PPDS) in ANP and compared PPDS with conservative treatment. METHODS: We prospectively enrolled patients (aged 18 - 75 years) diagnosed with ANP between February 2011 and July 2015. These patients were prospectively randomized to receive PPDS or conservative treatment at two tertiary centers. PPDS was performed as soon as possible after randomization. RESULTS: Concern regarding iatrogenic infections with pancreatic necrosis in the PPDS group prompted interim analysis, which confirmed a highly elevated risk. Thus, the trial was terminated prematurely for ethical reasons. Of the 11 patients in the PPDS group, all patients with successful pancreatic duct placement (5/5, 100 %) presented with infection, compared with only 3 of the 13 patients (23.1 %) in the conservative treatment group (P = 0.01). Analysis revealed success rates of 63.6 % for pancreatic duct cannulation, 45.5 % for pancreatic duct stenting, and 18.2 % for placement of a stent bridging the necrosis. Cannulation and stenting failures were due to duodenal edema and pancreatic duct stenosis. CONCLUSIONS: PPDS in ANP is associated with an unacceptably high risk of pancreatic necrosis infection. In addition, the procedure is technically challenging due to duodenal edema and ductal stenosis.

Strengths and Difficulties Questionnaire Assessment of Long-Term Psychological Outcome in Children After Intensive Care Admission.

OBJECTIVES: We investigated the long-term psychologic symptoms of patients who survived pediatric intensive care admission. DESIGN: Longitudinal follow-up study. SETTING: Nationwide cohort study based on a national ICU register and a questionnaire survey. PATIENTS: All pediatric patients (0-16 yr old) who were admitted to an ICU in Finland in 2009-2010. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Six years after ICU admission, all surviving patients were sent the Strengths and Difficulties Questionnaire, and questionnaires regarding chronic diseases and need for medication and therapy. At the end of the follow-up period, there were 3,674 surviving children who had been admitted to an ICU in 2009-2010. Of these children, 1,105 completed the Strengths and Difficulties Questionnaire 6 years after admission. Strengths and Difficulties Questionnaire scores were abnormal for 84 children (7.6%), borderline for 80 (7.2%), and normal for 941 (85.2%). Participants with abnormal scores were younger at admission to the ICU (3.06 vs 4.70 yr; p = 0.02), and more commonly had a chronic disease (79.5% vs 47.4%; p < 0.001), a need for continuous medication (49.4% vs 31.7%; p < 0.001), a need for therapy (58.5% vs 15.9%; p < 0.001), and a need for annual healthcare visits (91.4% vs 85.2%; p = 0.05). Abnormal Strengths and Difficulties Questionnaire scores were associated with higher rates of neurologic (32.1% vs 10.2%), gastrointestinal (7.1% vs 3.9%), psychiatric (3.6% vs 0.5%), and chromosomal disorders (9.5% vs 1.3%), as well as with long-term pain (1.2% vs 0.6%). CONCLUSIONS: Participants with abnormal Strengths and Difficulties Questionnaire scores (poor psychologic outcome) at 6 years after childhood ICU admission more commonly suffered neurologic, chromosomal, or psychiatric diagnoses or long-term pain, and generally required higher levels of healthcare services, therapies, and medication.

Factors related to delayed intensive care unit admission from emergency department-A retrospective cohort study.

BACKGROUND: The delays in transferring patients from emergency department (ED) to intensive care unit (ICU) are known to be linked with several adverse events, including prolonged ICU stay and increased hospital mortality. The factors associated with delayed ICU admission include shortage of ICU beds, organizational factors, ED overcrowding, and patient-related factors, including sepsis as admission diagnosis. The aim of this study was to examine ED-related factors associated with prolonged ED stay. METHODS: The study population consisted of adult patients admitted (n = 479) from ED to ICU between 31 May 2016 and 19 March 2017 in Oulu University Hospital. A patient's ED length of stay (LOS) exceeding 180 minutes was considered delayed. RESULTS: Most of the patients (380, 79.3%) were admitted to the ICU within 3 hours of hospital admission. In a logistic regression analysis, odds ratios (ORs) for ED LOS > 180 minutes were as follows: for Glasgow Coma Scale score > 9, 2.73 (1.39-5.32); for thrombocytes < 100 × 109 /mmol, 6.69 (2.32-19.26); for absence of pre-arrival notification, 5.27 (3.04-9.14); and for radiological examination, 3.95 (1.72-9.10). Trauma and intoxicated patients had shorter ED LOS while patients with medical conditions had more often prolonged admissions. CONCLUSION: The delays in ICU admissions were linked to therapeutic and diagnostic procedures and absence of pre-arrival notification. Patients were admitted to the ICU on the basis of diagnosis instead of clinical risk. However, the delays were not associated with worsening outcome, which indicates that sufficient care can be provided at the ED while the ICU admission is pending.

Swallowing-related quality of life after free flap surgery due to cancer of the head and neck.

PURPOSE: Treatment of head and neck cancers (HNC) often leads to impairment in speech and swallowing functions. This study evaluated swallowing problems and the impact of complications on swallowing-related QOL after free flap surgery for HNC. METHODS: Swallowing-related QOL was assessed using MDADI and SWAL questionnaires. RESULTS: Of 45 assessed patients, 25 (45.5%) had at least one postoperative complication. Patients reported less than < 86 points in 8/9 SWAL-QOL domains. The SWAL-QL total score or MDADI composite scores were not related to surgical complications. Those with medical complications had lower scores in SWAL-QOL domains of mental health (82.8 (21.8) vs 65.5 (24.2), p = 0.024) and sleep (77.6 (23.0) vs 52.3 (24.3), p = 0.003). CONCLUSIONS: In conclusion, swallowing related QOL is significantly impaired after 2 years of the tumor resection and free flap reconstruction for cancer of the head and neck, when using the cut-off value of 86 points in SWAL-QOL assessment tool. Surgical complications did not have an impact on swallowing-related QOL but medical complications were related to impairment in general QOL-related domains.

Five-Year Survival and Causes of Death in Children After Intensive Care-A National Registry Study.

OBJECTIVES: The aim of the study was to compare long-term mortality and causes of death in children post admission to an ICU with a control population of same age. DESIGN: Longitudinal follow-up study. SETTING: Registry study of a national ICU register and hospital registries. PATIENTS: Children admitted to an ICU in the years 2009 and 2010. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: The mortality and causes of death following ICU discharge were analyzed retrospectively. The median follow-up period was 4.9 years (25-75th percentiles, 4.4-5.5 yr). The causes of death in survivors 30 days after ICU discharge were compared with a cohort of 1 million children of the general population of same age. In total, 2,792 children were admitted to an ICU during the study period. Of those, 53 (1.9%) died in the ICU and 2,739 were discharged. Thirteen children died within 30 days of discharge, and 68 died between 30 days and the end of follow-up (December 31, 2014). In the control population (n = 1,020,407 children), there were 1,037 deaths (0.10%) from 2009 to 2014. The standardized mortality rate for the children admitted to the ICU during the study period was 53.4 (95% CI, 44.7-63.2). The standardized mortality rate for those children alive 1 year after discharge was 16.7 (12.1-22.6). One-year cumulative mortality was 3.3%. The most common causes of death in subjects alive 30 days post ICU were cancer (35.3%), neurologic (17.6%), and metabolic diseases (11.7%), whereas trauma was the most common cause in the control group (45.3%). CONCLUSIONS: There was an increased risk of death in a cohort of ICU-admitted children even 3 years after discharge. In those who survived 30 days after discharge, medical causes of death were dominant, whereas deaths due to trauma were most common in the control group.

Quality of life after free flap surgery for cancer of the head and neck in patients with or without postoperative complications.

BACKGROUND: Despite advances in surgical techniques, postoperative complications are frequent after free flap surgery for cancer of the head and neck. The present study assessed quality of life (QOL) in patients with and without postoperative complications. METHODS: QOL was evaluated using RAND-36, EORTC-C30 and H&N-35, and UW-QOL questionnaires. RESULTS: Of 53 assessed patients, 29 (54.7%) had at least one complication. Those with medical complications (n = 12, 22.6%) had significantly lower QOL in all domains of RAND-36 except emotional well-being. They also reported lower scores in EORTC-C30 domains of financial difficulties, pain, and insomnia and UW-QOL domains of pain, activity, and recreation. The QOL for patients without complications was comparable to the general population. CONCLUSION: QOL after free flap surgery for cancer of the head and neck is reduced in patients with postoperative medical complications.

Factors associated with time delay to angiography in acute ST-elevation myocardial infarction - A retrospective cohort study in Northern Finland.

BACKGROUND: The delay of percutaneous coronary intervention increases the risk of heart failure and mortality in STEMI. The aim of this study was to examine the time intervals of EMS and the factors associated with the time delay to angiography in patients with STEMI. METHODS: The present study was conducted in Northern Ostrobothnia, Finland in 2014-2016. All patients transported to the hospital by EMS who were diagnosed with STEMI and underwent a primary angiography within 24 h of arrival were included. Angiography was defined as delayed if it was performed over 120 min of the first medical contact (FMC). RESULTS: 310 patients met the inclusion criteria during the study period. Time from the FMC to angiography was less than 120 min in 231 patients (74.5%). In multivariate analysis, the factors associated with delayed angiography were the absence of chest pain (OR 2.46 (1.18-5.13),p = 0.016), dyspnea (OR 3.11 (1.54-6.28),p = 0.002), the treatment protocol violations by EMS (OR 2.41 (0.99-5.80),p = 0.050), treatment initiation at a primary health care center (OR 3.64 (1.39-9.48),p = 0.008), and the distance to hospital of over 100 km (OR 11.87 (6.14-22.93),p < 0.001). CONCLUSION: In our study, treatment protocol violations, non-specific symptoms, and the distance to hospital of over 100 km were associated with primary angiography in patients with STEMI transported to the hospital by EMS.

Factors associated with discrepancy between prescribed and administered enteral nutrition in general ICU.

BACKGROUND: Discrepancy between prescribed and administered enteral nutrition (EN) is a common problem during intensive care. The aim of this study was to find out the success rate and factors associated with inadequacy of enteral nutrition in a mixed general intensive care unit (ICU). METHODS: This was a retrospective single-center study of 892 patients with ICU length of stay (LOS) ≥4 days. The factors associated with adequacy of enteral nutrition on day 4 were analyzed. These included disease-specific factors, patient-related factors, severity of illness, and procedural factors. RESULTS: Of the 892 patients, 349 (39.1%) had an EN success rate of ≥70%, which was associated with a lower amount of prescribed enteral energy (500 kcal [500-800] vs. 800 kcal [500-1200], p < 0.001) and bolus administration of enteral nutrition (41 of 349 vs. 27 of 543, p < 0.001). Other factors impairing successful EN were severe inflammation, surgery, and GI-related admission diagnosis. CONCLUSIONS: On the fourth day during ICU stay discrepancy between prescribed and administered enteral nutrition was associated to severe inflammation, GI-related diagnosis, and prescribing policy.

Nutrition deficit during intensive care stay: incidence, predisposing factors and outcomes.

BACKGROUND: Adequate nutrition support during intensive care has several benefits including lower amount of infectious complications, improved wound healing, shorter length of stay (LOS) and decreased morbidity. The aim of the present study was to survey the adequacy of nutrition throughout Intensive Care Unit (ICU) stay and to examine various factors associated to cumulative nutrition inadequacy during ICU stay. METHODS: The study was a retrospective single center cohort study. The study population consisted of 1771 ICU adult (≥18 years) patients with emergency admission to ICU who had LOS between three and 40 days. Nutrition adequacy and factors associated to inadequate nutrition support during ICU stay were analyzed. RESULTS: Factors related to impaired energy balance were prescribed energy less than 25kcal/kg (OR 11.794 (9.017-15.427), P<0.001) and higher median CRP (OR 1.003 (1.001-1.004), P<0.001). Factors related to improved energy balance were length of stay (OR 0.975 (0.953-0.997), P=0.024), more than 30% Bolus enteral nutrition days (OR 0.314 (0.187-0.526), P<0.001) and Enteral/Parenteral -Ratio (OR 0.970 (0.953-0.987), P=0.001). CONCLUSIONS: The majority of ICU patients did not reach 60% of nutrition adequacy. Nutrition inadequacy was a common finding throughout the study population. Nutrition inadequacy might be partially avoidable since adequacy less than 60% was related to underprescription and failure to administer the prescribed nutrition. Bolus enteral nutrition might be an efficient method to deliver energy in ICU setting.

Prehospital and hospital delays for stroke patients treated with thrombolysis: A retrospective study from mixed rural-urban area in Northern Finland.

BACKGROUND: Thrombolysis improves stroke outcome, but efficacy of the treatment is limited by time. Therefore, recognition of stroke symptoms by dispatch centres and by emergency medical services (EMS) is crucial, as is minimization of pre-hospital delays. We investigated the pre-hospital delays in patients with stroke treated with thrombolysis and compared the delays between rural and urban patients. METHODS: Patients that had received thrombolysis at Oulu University Hospital (OUH) between 1 January 2013 and 31 December 2015 were identified. Patients were divided into urban and rural based on the site of the EMS mission. Pre-hospital charts and medical records were reviewed. Onset-to-dispatch, dispatch-to-arrival of EMS, on-scene, transport and door-to-needle times were studied. RESULTS: Three hundred one stroke patients were treated with thrombolysis at OUH, and 232 of them were included in the study. Positive Face Arm Speech Test (FAST) findings, priority dispatch code and transport code were associated with shorter transport delays. The priority dispatch was not used in 12.5% of stroke patients treated with thrombolysis. The rural patients had a four minutes longer dispatch-to-arrival delay and 50 (34, 74) minutes longer transport time. The door-to-needle time was 8 (5, 14) minutes shorter in rural patients than in urban patients. CONCLUSIONS: Positive FAST findings and the use of priority dispatch code and priority transport code were associated with shorter transport delays. There is room for improvement in door-to-needle time and in stroke recognition by the dispatch centre and EMS providers. For the rural population, helicopter transportation could reduce the long pre-hospital time.

Factors associated with impaired physical functioning and mental health in working-age patients attending a post-intensive care follow-up clinic three months after hospital discharge.

Patients recovering from critical illness are often suffering from remarkable limitations in their everyday life. The purpose of this study was to find factors associated with poor physical functioning and mental health after critical illness. The study was conducted among patients who met the inclusion criteria of our post-intensive care unit follow-up clinic. The patients were invited to the follow-up clinic three months after hospital discharge. The participants filled out a RAND-36 questionnaire, underwent a clinical examination and were stratified to those with good or poor recovery according to physical functioning and emotional wellbeing. Altogether 332 out of 351 follow-up clinic attendees had data available for analysis. In physical functioning 40% of patients achieved a poor outcome. In mental health the percentage was 8%. The patients with poor physical functioning had a longer hospital stay and were more likely to have received vasopressors. Eleven out of 16 (69%) multitrauma patients had poor physical functioning. Patients with poor physical functioning had more memories of pain, achieved worse results in a six-minute walk test and were less likely to be able to move independently. The patients with poor mental health had higher delirium incidence and fewer memories of relatives' visits and of nurses. The conclusions of this study were that the memories of pain, multitrauma and longer hospital stay were associated with a poor physical functioning outcome. Delirium and a lack of memories of relatives and nurses were associated with a poor mental health outcome.
