The effect of tourniquet use on postoperative opioid consumption after ankle fracture surgery - a retrospective cohort study

OBJECTIVES

A pneumatic tourniquet is often used during ankle fracture surgery to reduce bleeding and enhance the visibility of the surgical field. Tourniquet use causes both mechanical and ischemic pain. The main purpose of this study was to evaluate the effect of tourniquet time on postoperative opioid consumption after ankle fracture surgery.

METHODS

We retrospectively reviewed the files of 586 adult patients with surgically treated ankle fractures during the years 2014-2016. We evaluated post hoc the effect of tourniquet time on postoperative opioid consumption during the first 24 h after surgery. The patients were divided into quartiles by the tourniquet time (4-43 min; 44-58 min; 59-82 min; and ≥83 min). Multivariable linear regression analysis was used to evaluate the results.

RESULTS

Tourniquets were used in 486 patients. The use of a tourniquet was associated with an increase in the total postoperative opioid consumption by 5.1 mg (95 % CI 1.6-8.5; p=0.004) during the first 24 postoperative hours. The tourniquet time over 83 min was associated with an increase in the mean postoperative oxycodone consumption by 5.4 mg (95 % CI 1.2 to 9.7; p=0.012) compared to patients with tourniquet time of 4-43 min.

CONCLUSIONS

The use of a tourniquet and prolonged tourniquet time were associated with higher postoperative opioid consumption during the 24 h postoperative follow-up after surgical ankle fracture fixation. The need for ethical approval and informed consent was waived by the Institutional Review Board of Northern Ostrobothnia Health District because of the retrospective nature of the study.

Postoperative Complications and Outcome After Emergency Laparotomy: A Retrospective Study

BACKGROUND

Emergency laparotomy (EL) is a common urgent surgical procedure with high risk for postoperative complications. Complications impair the prognosis and prolong the hospital stay. This study explored the incidence and distribution of complications and their impact on short-term mortality after EL.

METHODS

This was a retrospective single-center register-based cohort study of 674 adults undergoing midline EL between May 2015 and December 2017. The primary outcome was operation-related or medical complication after EL. The secondary outcome was mortality in 90-day follow-up. Multivariate logistic regression analyses were used to identify independent risk factors for complications.

RESULTS

A total of 389 (58%) patients developed complications after EL, including 215 (32%) patients with operation-related complications and 361 (54%) patients with medical complications. Most of the complications were Clavien-Dindo classification type 4b (28%) and type 2 (22%). Operation-related complications occurred later compared to medical complications. Respiratory complications were the most common medical complications, and infections were the most common operation-related complications. The 30- and 90-day mortalities were higher in both the medical (17.2%, 26.2%) and operation-related complication groups (13.5%, 24.2%) compared to patients without complications (10.5% and 4.8%, 14.8% and 8.0%). Low albumin, high surgical urgency, excessive alcohol consumption and medical complications were associated with operation-related complications. Older age, high ASA class and operation-related complications were associated with medical complications.

CONCLUSIONS

This study demonstrated that EL is associated with a high risk of complications and poor short-term outcome. Complications impair the prognosis regardless of which kind of EL is in question.

Accuracy of dispatch and prehospital triage performance in poisonings - A retrospective study from northern Finland

BACKGROUND

Increasing numbers of dispatches place a burden on EMS; this study sought to assess the prehospital evaluation of poisoned patients transported to hospital. The primary aim of this study was to measure dispatch centre and EMS provider performance as well as factors contributing to the recognition of poisoning among prehospital patients. The secondary aim was to compare triage performance between dispatch centres and EMS providers.

METHODS

A retrospective single-centre study in Northern Finland was conducted. Patients suspected as poisonings by dispatch centres as well as other EMS-transported patients who received a diagnosis of poisoning in hospital between June 1, 2015 and June 1, 2017, were included.

RESULTS

There were a total of 1668 poisoning-related EMS missions. Dispatch centres suspected poisonings with sensitivity of 79.9% (95% CI 76.7-82.9) and specificity of 98.9% (95% CI 98.9-99.0) when all EMS missions were taken into account. In a logistic regression model, decreased state of consciousness as dispatch code (OR 7.18, 95% CI 1.90-27.05) and intravenous fluid resuscitation (OR 6.58, 95% CI 1.34-32.37) were associated with EMS transport providers not recognizing poisoning. Overtriage rate appeared significantly higher (33.6%, 95% CI 28.6-39.2) for dispatch when compared with transport (17.8%, 95% CI 13.9-22.6).

CONCLUSION

Dispatch centres seem to suspect poisonings fairly accurately. Poisonings unrecognized by EMS providers may be linked with intravenous fluid resuscitation and decreased patient consciousness. Overtriage appears to resolve somewhat from dispatch to transport. There were no fatal poisonings in this study population.

Outcomes in patients requiring intensive care unit (ICU) admission after emergency laparotomy - a retrospective study

Purpose

Outcomes after emergency laparotomy (EL) are poor. These patients are often admitted to an intensive care unit (ICU). This study explored outcomes in patients who were admitted to an ICU within 48 h after EL.

Materials and Methods

This retrospective single‐center registry study included all patients over 16 years of age that underwent an EL and were admitted to an ICU within 48 h after surgery in Oulu University Hospital, Finland between January 2005 and May 2015. Survival was followed until the end of 2019.

Results

We included 525 patients. Hospital mortality was 13.3%, 30‐day mortality was 17.3%, 90‐day mortality was 24.2%, 1‐year mortality was 33.0%, and 5‐year mortality was 59.4%. Survivors were younger (57 [45–70] years) than the non‐survivors (73 [62–80] years; p < .001). According to the Cox regression model, death during the follow‐up was associated with age, APACHE II‐score, lower postoperative CRP levels and platelet count of the first postoperative day, and the admission from the post‐anesthesia care unit (PACU) to the ICU instead of direct ICU admission.

Conclusion

Age, high APACHE II‐score, low CRP and platelet count, and admission from the PACU to the ICU associated with mortality after EL in patients admitted to an ICU within 48 h after EL.

Long-term Outcomes After Emergency Laparotomy: a Retrospective Study

BACKGROUND

Emergency laparotomy (EL) is a common surgical operation with poor outcomes. Patients undergoing EL are often frail and have chronic comorbidities, but studies focused on the long-term outcomes after EL are lacking. The aim of the present study was to examine the long-term mortality after EL.

METHODS

We conducted a retrospective single-center cohort study of 674 adults undergoing midline EL between May 2015 and December 2017. The follow-up lasted until September 2020. The primary outcome was 2-year mortality after surgery. The secondary outcome was factors associated with mortality during follow-up.

RESULTS

A total of 554 (82%) patients survived > 90 days after EL and were included in the analysis. Of these patients, 120 (18%) died during the follow-up. The survivors were younger than the non-survivors (median [IQR] 64 [49-74] vs. 71 [63-80] years, p < 0.001). In a Cox regression model, death during follow-up was associated with longer duration of operation (OR 2.21 [95% CI 1.27-3.83]), higher ASA classification (OR 2.37 [1.15-4.88]), higher CCI score (OR 4.74 [3.15-7.14]), and postoperative medical complications (OR 1.61 [1.05-2.47]).

CONCLUSIONS

Patient-related factors, such as higher ASA classification and CCI score, were the most remarkable factors associated with poor long-term outcome and mortality after EL.

The negative impact of interface design, customizability, inefficiency, malfunctions, and information retrieval on user experience: A national usability survey of ICU clinical information systems in Finland

INTRODUCTION

Clinical information systems (CISs) used in intensive care units (ICU) integrate large amounts of patient data every minute, and from multiple systems and devices. Intensive care requires efficient use of information technology to acquire, synchronize, integrate, and analyze data in order to make quick decisions and implement interventions in a timely manner.

OBJECTIVES

To identify factors affecting poor user experience (UX) of CISs used in ICUs in Finland.

METHODS

Data from national Electronic Health Record (EHR) and user experience survey was undertaken in 2017. Those, who used the ICU CIS on a daily or weekly basis were asked supplementary questions and, therefore, comprise a subset of the responses reported in this article.

RESULTS

On a 4-10 scale (i.e., "Fail" to "Excellent"), the mean 'grade' for the principally used ICU CIS was 6.9 (SD 1.3) points. Of the respondents, 119 (57%) were categorized as having good UX. The factors identified as affecting poor UX of the ICU CISs related to poor interface design (OR 7.8; 95% CIs 12.5-24.1; p = 0.001), insufficient customizability (OR 7.2; 95% CIs 1.7-30.6; p = 0.008), the inefficiency of performing routine tasks (OR 4.3; 95% CIs 1.0-18.2; p = 0.044), malfunctions (OR 3.5; 95% CIs 1.2-9.6; p = 0.019), and difficulties in information retrieval (OR 3.0; 95% CIs 1.0-8.8; p = 0.044). The most commonly reported usability problems with the main EHR system and ICU CISs were also identified.

CONCLUSIONS

Overall satisfaction with the principally used ICU CIS was moderate. However, the overall grades varied significantly. Poor interface design, insufficient customizability, inefficiency, malfunctions, and difficulties in information retrieval all affect poor UX.

Medical complications and outcome after endovascular therapy for acute ischemic stroke

AIM

Endovascular therapy (EVT) in acute stroke is an effective but invasive treatment which is frequently followed by various complications. The aim of the present study was to examine the rate of medical complications and other adverse events following EVT.

METHODS

Retrospective single-center study of 380 consecutive stroke patients who received EVT between the years 2015-2019.

RESULTS

A total of 234 (61.6%) patients had at least one recorded medical complication. The most common complication was pneumonia in 154 (40.5%) patients, followed by acute cardiac insufficiency in 134 (35.3%), and myocardial infarction in 22 (5.8%) patients. In multivariate analysis, the need for general anesthesia (OR 3.8 (1.9-7.7)), Charlson Comorbidity Index >3 (OR 1.3 (1.1-1.5)), male gender (1.9 (1.1-1.3)) and high National Institutes of Health Stroke Scale (NIHSS) score at admission (1.1 (1.0-1.2)) were associated with medical complications.

CONCLUSION

Medical complications are common among unselected stroke patients undergoing EVT. Both comorbidity and stroke severity have an influence on medical complications. Early recognition of complications is essential, because vast majority of patients encountering medical complications have a poor short-term outcome.

The development of emergency medical services benefit score: a European Delphi study

Background

The helicopter emergency services (HEMS) Benefit Score (HBS) is a nine-level scoring system developed to evaluate the benefits of HEMS missions. The HBS has been in clinical use for two decades in its original form. Advances in prehospital care, however, have produced demand for a revision of the HBS. Therefore, we developed the emergency medical services (EMS) Benefit Score (EBS) based on the former HBS. As reflected by its name, the aim of the EBS is to measure the benefits produced by the whole EMS systems to patients.

Methods

This is a four-round, web-based, international Delphi consensus study with a consensus definition made by experts from seven countries. Participants reviewed items of the revised HBS on a 5-point Likert scale. A content validity index (CVI) was calculated, and agreement was defined as a 70% CVI. Study included experts from seven European countries. Of these, 18 were prehospital expert panellists and 11 were in-hospital commentary board members.

Results

The first Delphi round resulted in 1248 intervention examples divided into ten diagnostic categories. After removing overlapping examples, 413 interventions were included in the second Delphi round, which resulted in 38 examples divided into HBS categories 3–8. In the third Delphi round, these resulted in 37 prehospital interventions, examples of which were given revised version of the score. In the fourth and final Delphi round, the expert panel was given an opportunity to accept or comment on the revised scoring system.

Conclusions

The former HBS was revised by a Delphi methodology and EBS developed to represent its structural purpose better. The EBS includes 37 exemplar prehospital interventions to guide its clinical use.

Trial registration The study permission was requested and granted by Turku University Hospital (decision number TP2/010/18).

Alcohol consumption is associated with a later need for ICU admission: a Northern Finland Birth Cohort 1966-study

BACKGROUND

Alcohol-related problems are common in intensive care unit (ICU) admitted patients. The aim of the present study is to assess the impact of alcohol consumption on the need of intensive care in 19 years follow-up period.

METHODS

The study population consists of Northern Finland Birth Cohort 1966 participants, who responded alcohol-related questions at 31 years of age and Intensive Care Unit (ICU admissions from 1997 to 2016.

RESULTS

There were a total of 8379 assessed people and 136 (1.6%) of them were later admitted to ICU. A total of 44 (32.4%) of the ICU-admitted persons had their alcohol consumption at the highest quartile of the cohort (P = 0.047). These patients had a lower number of malignancy-related admissions (3.6% versus 14.0%, P = 0.027), neurological admissions (14.3 versus 30.6%, P = 0.021), and were more often admitted due to poisonings (12.5% versus 5.0%, P = 0.07). There were no differences in 28-day post-ICU mortality but long-term mortality of ICU-admitted patients with lower alcohol consumption was higher than non-ICU-admitted population.

CONCLUSION

Among ICU-admitted population, there was higher alcohol consumption at age of 31 years. People in the lower alcohol consumption quartiles were more often admitted to ICU due to malignancy-related causes and they had higher long-term mortality.

Emergency department admission and mortality of the non-transported emergency medical service patients: a cohort study from Northern Finland

OBJECTIVES

A high number of emergency medical service (EMS) patients are not transported to hospital by ambulance. Various non-transport protocols and guidelines have been implemented by different EMS providers. The present study examines subsequent tertiary care ED and hospital admission and mortality of the patients assessed and not transported by EMS in Northern Finland and evaluates the factors predicting these outcomes.

METHODS

Data from EMS missions with a registered non-transportation code during 1 January 2018-31 December 2018 were screened retrospectively. EMS charts were retrieved from a local EMS database and data concerning hospital admission and mortality were collected from the medical records of Oulu University Hospital, Oulu, Finland.

RESULTS

A total of 12 530 EMS non-transport missions were included. Of those, a total of 344 (2.7%) patients were admitted to tertiary care ED in 48 hours after the EMS contact, and 229 (1.8%) of them were further admitted to the hospital. Patients with the dispatch code 'abdominal pain', clinical presentation with fever or hyperglycaemia, physician phone consultation and a decision not to transport during night hours were associated with a higher risk of ED admission within 48 hours after EMS contact. Overall 48-hour and 30-day mortalities of non-transported patients were 0.2% (n=25) and 1.0% (n=128), respectively.

CONCLUSION

In this cohort, the rate of subsequent tertiary care ED admission and mortality in the non-transported EMS patients was low. Dispatch code abdominal pain, clinical presentation with fever or hyperglycaemia, physician phone consultation and night-hours increased the risk of ED admission within 48 hours after EMS contact.

Early impact of the COVID-19 pandemic and social restrictions on ambulance missions

Background

The SARS-CoV-2 coronavirus disease 2019 (COVID-19) has had a major impact on health care services globally. Recent studies report that emergency departments have experienced a significant decline in the number of admitted patients in the early phase of the pandemic. To date, research regarding the influence of COVID-19 on emergency medical services (EMS) is limited. This study investigates a change in the number and characteristics of EMS missions in the early phase of the pandemic.

Methods

All EMS missions in the Northern Ostrobothnia region, Finland (population 295 500) between 1 March to 30 June 2020 were screened and analyzed as the study group. A control group was composed from the EMS calls between the corresponding months in the years 2016–19.

Results

A total of 74 576 EMS missions were screened for the study. Within the first 2 months after the first COVID-19 cases in the study area, the decline in the number of EMS missions was 5.7–13% compared with the control group average. EMS time intervals (emergency call to dispatch, dispatch, en-route, on-scene and hospital handover) prolonged in the COVID-19 period. Dispatches concerning mental health problems increased most in the study period (+1.2%, P < 0.001). Only eleven confirmed COVID-19 infections were encountered by EMS in the study period.

Conclusion

Our findings suggest that the present COVID-19 pandemic and social restrictions lead to changes in the EMS usage. These preliminary findings emphasize the importance of developing new strategies and protocols in response to the oncoming pandemic waves.

Nutrition delivery after emergency laparotomy in surgical ward: a retrospective cohort study

PURPOSE

Adequate nutrition after major abdominal surgery is associated with less postoperative complications and shorter hospital length of stay (LOS) after elective procedures, but there is a lack of studies focusing on the adequacy of nutrition after emergency laparotomies (EL). The aim of the present study was to investigate nutrition adequacy after EL in surgical ward.

METHODS

The data from 405 adult patients who had undergone emergency laparotomy in Oulu University Hospital (OUH) between years 2015 and 2017 were analyzed retrospectively. Nutrition delivery and complications during first 10 days after the operation were evaluated.

RESULTS

There was a total of 218 (53.8%) patients who were able to reach cumulative 80% nutrition adequacy during the first 10 postoperative days. Patients with adequate nutrition (> 80% of calculated calories) met the nutritional goals by the second postoperative day, whereas patients with low nutrition delivery (< 80% of calculated calories) increased their caloric intake during the first 5 postoperative days without reaching the 80% level. In multivariate analysis, postoperative ileus [4.31 (2.15-8.62), P < 0.001], loss of appetite [3.59 (2.18-5.93), P < 0.001] and higher individual energy demand [1.004 (1.003-1.006), P = 0.001] were associated with not reaching the 80% nutrition adequacy.

CONCLUSIONS

Inadequate nutrition delivery is common during the immediate postoperative period after EL. Oral nutrition is the most efficient way to commence nutrition in this patient group in surgical ward. Nutritional support should be closely monitored for those patients unable to eat.

Causes of death for intensive care survivors with and without acute kidney injury in 5-year follow-up

BACKGROUND

Data on the causes of death and long-term mortality of intensive care unit-treated hospital survivors with acute kidney injury (AKI) are limited. The goal of this study was to analyze the causes of death among critically ill patients during a 5-year follow-up.

METHODS

In this predetermined sub-study of a prospective, observational, multi-center cohort from the FINNAKI study, we analyzed 2436 patients who were discharged from the hospital. Statistics Finland provided the follow-up data and causes of death.

RESULTS

During the follow-up, 765 (31%) patients died, of whom 295 (39%) had AKI and 73 (9.5%) had received renal replacement therapy. More than half of the deaths in both the non-AKI and AKI groups occurred after the 1 year follow-up (58% vs. 54%, respectively). The three most common causes of death in AKI were cardiovascular diseases (36%), malignancies (21%), and neurological diseases (11%). In early deaths (<90 days) cardiovascular causes were more prevalent in AKI patients compared to non-AKI (38% vs 25%, P = .037.) In six cases (0.8%), the main cause of death was kidney disease, out of which five were in the AKI group. In patients with cardiovascular causes, the median time to death was shorter in AKI patients compared to non-AKI patients (508 vs 816 days, P = .018).

CONCLUSION

Cardiovascular causes and malignancies account for more than half of the causes of death in patients who had suffered AKI, while death from kidney disease after AKI is rare. Early cardiovascular deaths are more prevalent in AKI compared to non-AKI patients.

Treatment profile and long-term outcome of intensive care unit-admitted patients with liver cirrhosis or other liver disease in relation to alcohol consumption

OBJECTIVE

To examine the impact of alcohol consumption on the treatment profile, mortality and causes of death in intensive care unit (ICU)-admitted patients with liver cirrhosis and other liver disease.

METHODS

Data on liver disease and ICU treatment of patients with previously diagnosed liver disease between 2015 and 2017 were retrospectively collected from medical records at Oulu University Hospital, Finland. The median follow-up was 367 days. The causes of death were obtained from Statistics Finland.

RESULTS

From 250 patients, high-risk alcohol consumption was present in 74.7% (71 of 95) cirrhotic patients and 43.2% (67 of 155) patients in the other liver disease group. Gastrointestinal causes were the most common admission causes. Despite the higher SOFA scores in the alcoholic liver cirrhosis patients compared with the non-alcoholic cirrhosis, there were no differences in the need for organ support, length of ICU stay or outcome between the groups or the subgroups. There were no differences in 1-year mortality between the cirrhosis groups (alcoholic cirrhosis 43.7% versus non-alcoholic cirrhosis 45.8%, p = 1.0) or between the other liver disease groups (patients with alcohol consumption 37.3% versus patients without alcohol consumption 36.4%, p = 1.0). The patients with high-risk alcohol consumption died more often due to liver disease, whereas the patients without high-risk alcohol consumption died often due to malignancies.

CONCLUSIONS

We report no significant impact of alcohol consumption on the ICU treatment profile or mortality of patients with cirrhosis or other liver disease. The high mortality underlines the importance of preventive measures after ICU admission.

Persistent pain in intensive care survivors: a systematic review

BACKGROUND

According to earlier studies where the main aim has been quality of life, there is growing evidence of increased levels of persistent pain in survivors of critical illness. The cause of admission and several factors during intensive care may have associated risk factors for pain persistence. This systematic review aims to determine the incidence or prevalence of persistent pain after critical illness and to identify risk factors for it.

METHODS

Six databases were searched, and eventually nine studies were included in the final systematic process. The validity of observational and cross-sectional studies was analysed using the National Institute of Health 'Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies'.

RESULTS

The incidence of persistent pain after intensive care varied from 28% to 77%. Risk factors for persistent pain were acute pain at discharge from ICU, higher thoracic trauma score, surgery, pre-existing pain, organ failure, longer length of ventilator or hospital stay, and sepsis. No difference in incidence between medical and surgical patients was found.

CONCLUSIONS

New systematic, observational studies are warranted to identify persistent pain-related factors in intensive care to improve pain management protocols and thereby diminish the risk of persistent pain after ICU stay.

Use of prehospital emergency medical services according to income of residential area

Background

The increasing usage of emergency medical services (EMS) missions is a challenge in modern practice. This study was designed to examine the association of the income level of residential areas on the rate of EMS missions and the frequency of EMS use in these areas.

Methods

All EMS missions for adult patients (>18 years) encountered by one rescue department in Northern Finland between June 2015 and May 2017 were analysed. The area served was categorised into four categories, according to the median annual income of the postal code areas. EMS missions per 1000 person-years, rate of non-transport missions and the number of dispatches to frequent (>4 EMS calls/year and highly frequent (>10 calls/year)EMS users per area were investigated.

Results

There were 62 759 EMS missions, 34.8% of which resulted in non-transport. The crude rate of EMS dispatches was higher in the low-income area compared with other income areas (133.3 vs 108.9 vs 111.3 vs 73.6/1000 person-years) as well as the rate of high-frequency user dispatches (21.5 vs 11.5 vs 7.2 vs 4.3/1000-person years). The rate of non-transports missions was higher also (69.4 vs 43.4 vs 42.5. vs 30.6/1000 person-years). The highest crude rate of EMS use was found in people older than 65 years living in the lowest income areas (294.8/1000 person-years). After age adjustment, the highest rate of EMS use was found in rural areas with the lowest income (146.3/1000 person-years).

Conclusions

The rate of the EMS missions and non-transport missions differs significantly among different income areas. Resource usage was significantly higher in the low income areas. This information can be used in planning allocation of EMS and preventive healthcare resources.

Pantoprazole in ICU patients at risk for gastrointestinal bleeding-1-year mortality in the SUP-ICU trial

BACKGROUND

The long-term effects of stress ulcer prophylaxis with pantoprazole are unknown in ICU patients. We report 1-year mortality outcome in the Stress Ulcer Prophylaxis in the Intensive Care Unit (SUP-ICU) trial.

METHODS

In the SUP-ICU trial, acutely admitted adult ICU patients at risk of gastrointestinal bleeding were randomised to intravenous pantoprazole 40 mg vs placebo (saline) once daily during their ICU stay. We assessed mortality at 1 year and did sensitivity analyses according to the trial protocol and statistical analysis plan.

RESULTS

A total of 3261 of the 3291 patients with available data (99.1%) were followed up at 1 year after randomisation; 1635 were allocated to pantoprazole and 1626 to placebo. At 1 year after randomisation, 610 of 1635 patients (37.3%) had died in the pantoprazole group as compared with 601 of 1626 (37.0%) in the placebo group (relative risk, 1.01; 95% confidence interval 0.92-1.10). The results were consistent in the sensitivity analysis adjusted for baseline risk factors and in those of the per-protocol population. We did not observe heterogeneity in the effect of pantoprazole vs placebo on 1-year mortality in the predefined subgroups, that is, patients with and without shock, mechanical ventilation, liver disease, coagulopathy, high disease severity (SAPS II > 53) or in medical vs surgical ICU patients.

CONCLUSION

We did not observe a difference in 1-year mortality among acutely admitted adult ICU patients with risk factors for gastrointestinal bleeding allocated to stress ulcer prophylaxis with pantoprazole or placebo during the ICU stay. (The SUP-ICU trial was funded by Innovation Fund Denmark and others; ClinicalTrials.gov number, NCT02467621).

Characteristics of subjects with alcoholic cardiomyopathy and sudden cardiac death

OBJECTIVE

To study social and clinical characteristics of victims of sudden cardiac death (SCD) due to alcoholic cardiomyopathy (ACM).

METHODS

The study population comprised a subset of Fingesture cohort. All subjects were verified SCD victims determined to have ACM as cause of death in medico-legal autopsy between 1998 and 2017 in Northern Finland. The Finnish Population Register Centre provided SCD victims' last place of residence. Population data of residential area were obtained from Statistics Finland.

RESULTS

From a total of 5869 SCD victims in Fingesture cohort, in 290 victims the cause of SCD was ACM (4.9%; median age 56 (50-62) years; 83% males). In 64 (22.1%) victims, the diagnosis of cardiac disease was made prior to death and in 226 (77.9%) at autopsy. There were no significant differences in autopsy findings between victims with or without known cardiac diagnosis, but steatohepatitis (94.5%) and liver cirrhosis (64,5%) were common in both groups. Alcoholism was more often recorded in the known cardiac disease group (64.1% vs 47.3%, p=0.023). Majority were included in the working age population (ie, under 65 years) (54.8% and 53.1%, p=0.810). In high-income communities, 28.8% of ACM SCD victims had previously diagnosed cardiac disease, the proportion in the middle-income and low-income communities was 18.6% (p=0.05).

CONCLUSIONS

Majority of SCD victims due to ACM did not have previously diagnosed cardiac disease, but documented risk consumption of alcohol was common. This emphasises the importance of routine screening of alcohol consumption and signs of cardiomyopathy in heavy alcohol users in primary healthcare.

Spinal or general anaesthesia for lower-limb amputation in peripheral artery disease - a retrospective cohort study

BACKGROUND

The present study aimed to determine which method of anaesthesia (spinal anaesthesia or general anaesthesia) is better in reducing post-operative analgesic requirements in patients undergoing major limb amputation for lower-limb ischaemia. Another aim was to find out if anaesthesiologists use neuraxial anaesthesia in high-risk patients despite abnormal coagulation profile or use of anticoagulation.

METHODS

The study was a retrospective cohort study. All patients undergone above-the-knee amputation or below-the-knee amputation due to peripheral artery disease between 1996 and 2010 were reviewed to evaluate post-operative opioid consumption and complications.

RESULTS

A total of 434 amputations in 323 patients were included in the study. The number of surgical complications, the need for surgical revision and the number of intensive care unit admissions were significantly higher in the general anaesthesia group. The need for post-operative opioid medication was significantly lower in patients with above-the-knee amputation and spinal anaesthesia. The use of post-operative epidural analgesia did not reduce analgesic requirements. In the present study, there were patients who received neuraxial anaesthesia despite abnormal coagulation profile or uninterrupted warfarin or clopidogrel. There were no reported cases of spinal or epidural haematoma.

CONCLUSION

Patients with spinal anaesthesia had a lower rate of surgical complications, re-operations and intensive care unit admissions. Patients with above-the-knee amputation and spinal anaesthesia had a lesser need for opioid medication in the post-operative period than patients with general anaesthesia. Anaesthesiologists performed neuraxial anaesthesia and/or analgesia in high-risk patients despite abnormal coagulation profile or ongoing anticoagulation, but no adverse outcomes were reported.

Do pre-hospital poisoning deaths differ from in-hospital deaths? A retrospective analysis

Background

Most fatal poisonings occur outside the hospital and the victims found dead. The purpose of this study was to determine the general pattern and patient demographics of fatal poisonings in Northern Finland. In particular, we wanted to analyze differences between pre-hospital and in-hospital deaths.

Methods

All fatal poisonings that occurred in Northern Finland in 2007–2011 were retrieved from the Cause of Death Registry provided by Statistics Finland. We noted the patient demographics, causal agents, and other characteristics of the poisoning events.

Results

A total of 689 fatal poisonings occurred during the study period, of which only 42 (6.1%) reached the hospital alive. Those who died pre-hospital were significantly younger (50 vs. 56 years, p = 0.04) and more likely to be male (77% vs. 57%, p = 0.003). Cardiopulmonary resuscitation was attempted less often in pre-hospital cases (9.9% vs. 47.6%, p < 0.001). Ethanol was more frequently the main toxic agent in pre-hospital deaths (58.4% vs. 26.2%, p < 0.001), and multiple ingestions were more common (52.2% vs. 35.7%, p < 0.001) in pre-hospital deaths.

Discussion

Most of the pre-hospital fatal poisoning victims are found dead and the majority of in-hospital victims are admitted to hospital in an already serious condition. According to results of this and former studies, prevention seems to be the most important factor in reducing deaths due to poisoning.

Conclusions

The majority of poisoning-related deaths occur pre-hospital and are related to alcohol intoxication and multiple ingestions.

Evaluating helicopter emergency medical missions: a reliability study of the HEMS benefit and NACA scores

BACKGROUND

The benefits of the Helicopter Emergency Medical Service (HEMS) and dispatch accuracy are continuously debated, and a widely accepted score to measure the benefits of the mission is lacking. The HEMS Benefit Score (HBS) has been used in Finnish helicopter emergency medical services, but studies are lacking. The National Advisory Committee for Aeronautics (NACA) score is widely used to measure the severity of illness or injury in the pre-hospital setting, but it has many critics due to its subjectivity. We investigated the inter-rater and rater-against-reference reliability of these scores.

METHODS

Twenty-five fictional HEMS missions were created by an expert panel. A total of 22 pre-hospital physicians were recruited to participate in the study from two different HEMS bases. The participants received written instructions on the use of the scores. Intraclass correlation coefficients (ICCs) and mean differences between rater-against-reference values were calculated.

RESULTS

A total of 17 physicians participated in the study. The ICC was 0.70 (95% CI 0.57-0.83) for the HBS and 0.65 (95% CI 0.51-0.79) for the NACA score. Mean differences between references and raters were -0.09 (SD 0.72) for the HBS and 0.28 (SD 0.61) for the NACA score, indicating that raters scored some lower NACA values than reference values formed by an expert panel.

CONCLUSION

The HBS and NACA score had substantial inter-rater reliability. In addition, the rater-against-reference values were acceptable, though large differences were observed between individual raters and references in some clinical cases.

Fatal injuries in rural and urban areas in northern Finland: a 5-year retrospective study

Background

Finland has the fourth highest injury mortality rate in the European Union. To better understand the causes of the high injury rate, and prevent these fatal injuries, studies are needed. Therefore, we set out to complete an analysis of the epidemiology of fatal trauma, and any contributory role for alcohol, long suspected to promote fatal injuries. As a study area, we chose the four northernmost counties of Finland; their mix of remote rural areas and urban centres allowed us to correlate mortality rates with ‘rurality’.

Methods

The Causes of Death Register was consulted to identify deaths from external causes over a 5‐year time period. Data were retrieved from death certificates, autopsy reports and medical records. The municipalities studied were classified as either rural or urban.

Results

Of 2915 deaths categorized as occurring from external causes during our study period, 1959 were eligible for inclusion in our study. The annual crude mortality rate was 54 per 100,000 inhabitants; this rate was higher in rural vs. urban municipalities (65 vs. 45 per 100,000 inhabitants/year). Additionally, a greater number of pre‐hospital deaths from accidental high‐energy trauma occurred in rural areas (78 vs. 69%). 42% of all pre‐hospital deaths occurred under the influence of alcohol.

Conclusion

The crude mortality rate for fatal injuries was high overall as compared to other studies, and elevated in rural areas, where pre‐hospital deaths were more common. Almost half of pre‐hospital deaths occurred under the influence of alcohol.

Vitamin D deficiency at admission is not associated with 90-day mortality in patients with severe sepsis or septic shock: Observational FINNAKI cohort study

Introduction Low levels of vitamin D have been associated with increased mortality in patients that are critically ill. This study explored whether vitamin D levels were associated with 90-day mortality in severe sepsis or septic shock. Methods Plasma vitamin D levels were measured on admission to the intensive care unit (ICU) in a prospective multicentre observational study. Results 610 patients with severe sepsis were included; of these, 178 (29%) had septic shock. Vitamin D deficiency (<50 nmol/L) was present in 333 (55%) patients. The 90-day mortality did not differ among patients with or without vitamin D deficiency (28.3% vs. 28.5%, p = 0.789). Diabetes was more common among patients deficient compared to those not deficient in vitamin D (30% vs. 18%, p < 0.001). Hospital-acquired infections at admission were more prevalent in patients with a vitamin D deficiency (31% vs. 16%, p < 0.001). A multivariable adjusted Cox regression model showed that low vitamin D levels could not predict 90-day mortality (<50 nmol/L: hazard ratio (HR) 0.99 (95% CI: 0.72-1.36), p > 0.9; and <25 nmol/L: HR 0.44 (95% CI: 0.22-0.87), p = 0.018). Conclusions Vitamin D deficiency detected upon ICU admission was not associated with 90-day mortality in patients with severe sepsis or septic shock. Key messages In severe sepsis and septic shock, a vitamin D deficiency upon ICU admission was not associated with increased mortality. Compared to patients with sufficient vitamin D, patients with deficient vitamin D more frequently exhibited diabetes, elevated C-reactive protein levels, and hospital-acquired infections upon ICU admission, and they more frequently developed acute kidney injury.

Short-term outcome and differences between rural and urban trauma patients treated by mobile intensive care units in Northern Finland: a retrospective analysis

Background

Emergency medical services are an important part of trauma care, but data comparing urban and rural areas is needed. We compared 30-day mortality and length of intensive care unit (ICU) stay for trauma patients injured in rural and urban municipalities and collected basic data on trauma care in Northern Finland.

Methods

We examined data from all trauma patients treated by the Finnish Helicopter Emergency Medical Services in 2012 and 2013. Only patients surviving to hospital were included in the analysis but all pre-hospital deaths were recorded. All data was retrieved from the national Helicopter Emergency Medical Services database, medical records, and the Finnish Causes of Death Registry. Patients were defined as urban or rural depending on the type of municipality where the injury occurred.

Results

A total of 472 patients were included. Age and Injury Severity Score did not differ between rural and urban patients. The pre-hospital time intervals and distances to trauma centers were longer for rural patients and a larger proportion of urban patients had intentional injuries (23.5 % vs. 9.3 %, P <0.001). The 30-day mortality for severely injured patients (Injury Severity Score >15) was 23.9 % in urban and 13.3 % in rural municipalities. In the multivariate regression analysis the odds ratio (OR) for 30-day mortality was 2.8 (95 % confidence interval 1.0 to 7.9, P = 0.05) in urban municipalities. There was no difference in the length of ICU stay or scores. Twenty patients died on scene or during transportation and 56 missions were aborted because of pre-hospital death.

Conclusions

The severely injured urban trauma patients had a trend toward higher 30-day mortality compared with patients injured in rural areas but the length of ICU stay was similar. However, more pre-hospital deaths occurred in rural municipalities. The time before mobile ICU arrival appears to be critical for trauma patients’ survival, especially in rural areas.

Decompressive hemicraniectomy for treatment of space occupying ischemic stroke after repair of type-A aortic dissection

Postoperative stroke after cardiac surgery is often a lethal complication. Herein, we report on a patient who suffered space-occupying ischemic stroke after surgical treatment of type A aortic dissection. He underwent decompressive hemicraniectomy and, despite residual hemianopsia and left side flaccid hemiplegia, survived surgery and was discharged for rehabilitation. This observation suggests that early consultation with a neurosurgeon, intracranial pressure monitoring and, when indicated, decompressive hemicraniectomy should be considered in order to reduce the high mortality rate associated with ischemic stroke after cardiac surgery.

Aspiration pneumonia following severe self-poisoning

PURPOSE

To investigate the risk factors of aspiration pneumonia following severe self-poisoning.

MATERIALS AND METHODS

Patients treated due to severe self-poisoning in the ICU of Oulu University Hospital, Oulu, Finland during 1.11.1989-31.10.2000 were analyzed retrospectively.

RESULTS

28.4% of 257 patients fulfilled the criteria of aspiration pneumonia. An unconscious patient who was not intubated until arrival at the emergency room (ER) had an odds ratio (OR) of 3.34 (CI 1.3-8.7) for aspiration pneumonia. If the patient was intubated at the first contact with health care providers, OR was 1.8 (CI 0.6-5.7). The use of gastric lavage or activated charcoal in the case of a non-intubated unconscious patient led to ORs of 2.7 (CI 0.8-9.3) and 3.7 (CI 1.01-12.5), respectively. The mean length of ICU stay was 0.9 (CI 0.8-0.9) days among patients without aspiration pneumonia and 1.9 (CI 1.3-2.6) days among those with aspiration pneumonia. The mean length of hospital stay was 2.8 (CI 2.5-3.1) days among the patients without aspiration pneumonia and 6.5 (CI 5.3-7.6) days among those with aspiration pneumonia.

CONCLUSION

To avoid aspiration pneumonia intubation of an unconscious patient on scene before arrival at the ER is recommended. The use of gastric lavage and activated charcoal increase the risk of aspiration pneumonia if the patient is unconscious and not intubated. Aspiration pneumonia significantly prolongs the length of ICU and hospital stay.
