Identifying performance indicators to measure overall performance of telephone triage - a scoping review.

OBJECTIVE: This article aims to summarize performance indicators used in telephone triage services research, and make recommendations for the selection of valid indicators to measure the performance of telephone triage. We describe what kind of frameworks, performance indicators, or variables have been used for evaluating telephone triage performance by systematically mapping the telephone triage performance measurement. The objective was to find measures for each Triple Aim dimension. DESIGN: A scoping review method was used following Joanna Briggs Institute guidelines. Using this method, we defined indicators to measure the performance of telephone triage. We used the Triple Aim framework to identify indicators to measure the overall performance of telephone triage. The Triple Aim framework consists of improving the patient experience of care, improving the health of populations, and reducing cost per capita. SETTING: The scoping review was performed using CINAHL, Medline, EBSCOhost, and PubMed electronic databases. The eligibility criterion was research published in English between 2015 and 2023. The inclusion focused on the use and performance of telephone triage services and system-focused studies. RESULTS: A total of 1098 papers were screened for inclusion, with 57 papers included in our review. We identified 13 performance indicators covering all Triple Aim dimensions: waiting times, access, patient satisfaction, the accuracy of triage decision, severity and urgency of the symptoms, triage response, patient compliance with the advice given, follow-up healthcare service use, and running costs of service. We didn't find any earlier framework covering all Triple Aim dimensions properly. CONCLUSIONS: Measuring the performance of telephone triage requires an extensive and comprehensive approach. We presented performance indicators that may be included in the framework for measuring the performance of telephone triage to support overall performance measurements of telephone triage.

Impact of a Conformité Européenne (CE) Certification-Marked Medical Software Sensor on COVID-19 Pandemic Progression Prediction: Register-Based Study Using Machine Learning Methods.

BACKGROUND: To address the current COVID-19 and any future pandemic, we need robust, real-time, and population-scale collection and analysis of data. Rapid and comprehensive knowledge on the trends in reported symptoms in populations provides an earlier window into the progression of viral spread, and helps to predict the needs and timing of professional health care. OBJECTIVE: The objective of this study was to use a Conformité Européenne (CE)-marked medical online symptom checker service, Omaolo, and validate the data against the national demand for COVID-19-related care to predict the pandemic progression in Finland. METHODS: Our data comprised real-time Omaolo COVID-19 symptom checker responses (414,477 in total) and daily admission counts in nationwide inpatient and outpatient registers provided by the Finnish Institute for Health and Welfare from March 16 to June 15, 2020 (the first wave of the pandemic in Finland). The symptom checker responses provide self-triage information input to a medically qualified algorithm that produces a personalized probability of having COVID-19, and provides graded recommendations for further actions. We trained linear regression and extreme gradient boosting (XGBoost) models together with F-score and mutual information feature preselectors to predict the admissions once a week, 1 week in advance. RESULTS: Our models reached a mean absolute percentage error between 24.2% and 36.4% in predicting the national daily patient admissions. The best result was achieved by combining both Omaolo and historical patient admission counts. Our best predictor was linear regression with mutual information as the feature preselector. CONCLUSIONS: Accurate short-term predictions of COVID-19 patient admissions can be made, and both symptom check questionnaires and daily admissions data contribute to the accuracy of the predictions. Thus, symptom checkers can be used to estimate the progression of the pandemic, which can be considered when predicting the health care burden in a future pandemic.

Cancer Incidence of Finnish Sami in the Light of Exposure to Radioactive Fallout.

This article summarizes the results of studies on the exposure of the Finnish Sami people to radioactive fallout and the estimations of the related cancer risk. We also discuss the lifestyle, genetic origin and diet of this population. The Sami people are an indigenous people who live in the northern part of Scandinavia and Finland. The review is based on the available scientific literature of Finnish Sami. The traditional Sami diet, high in animal products, persists in Sami groups still involved in reindeer-herding, but others have adopted the typical diet of western cultures. Studies have consistently shown an overall reduced cancer risk among the Finnish Sami people, except for stomach cancer among the Skolt Sami. Common cancers among the Finnish main population, such as prostate, breast and skin cancer are especially rare among the Finnish Sami. The incidence of cancer among the Finnish Sami are mostly similar to those of the Swedish and Norwegian Sami. To conclude, we observed no effect of radioactive pollution on cancer incidence. The lifestyles and environments of the Sami are changing, and their cancer mortality rate today is similar to that of the majority of the Finnish and western population.

Use and Users of the Web-Based Omaolo Covid-19 Symptom Self-Assesment Tool in Finland Since March 16, 2020.

In Finland, it is possible to quickly produce medical symptom self-assessment tools within the existing infrastructure. The Finnish Omaolo Covid-19 web-based symptom self-assessment tool (symptom checker) was launched on March 16, 2020 after a 6-day development period. By using the web-based Omaolo Covid-19 symptom checker during the second wave of the epidemic, some 1.72 million questionnaires were recorded, out of which 1.55 million from symptomatic persons. Some 15% of the responses (245,500) were directed to seek emergency medical care based on the online screening by respondent response profiles.

The predictive value of NT-proBNP and hs-TnT for risk of death in cardiac surgical patients.

BACKGROUND: European System for Cardiac Operative Risk Evaluation II (EuroSCORE II) is used for risk stratification before cardiac surgery, but whether N-terminal pro-B-type natriuretic peptide (NT-proBNP) and high-sensitivity troponin T (hs-TnT) may add prognostic information to EuroSCORE II is not known. METHODS: Preoperative (n=640) and postoperative (n=629) blood samples were available from cardiac surgical patients with 961-day follow-up (FINNAKI Heart study; cohort #1). The accuracy of a parsimonious risk model with NT-proBNP measurements was also tested in 90 patients with respiratory failure after cardiac surgery (FINNALI study; cohort #2). RESULTS: Sixty-one patients (9.5%) died during follow-up in cohort #1. Preoperative NT-proBNP and hs-TnT concentrations correlated (rho=0.58; p<0.001) and were higher in non-survivors compared to survivors: median 2027 (Q1-3 478-5387) vs. 373 (134-1354) ng/L [NT-proBNP] and 39 (16-191) vs. 13 (8-32) ng/L [hs-TnT]; p<0.001 for both. Preoperative NT-proBNP concentrations were associated with time to death after adjustment for EuroSCORE II (HR [lnNT-proBNP] 1.33 [95% CI 1.08-1.64]), p=0.008 and reclassified patients on top of EuroSCORE II (net reclassification index 0.39 [95% CI 0.14-0.64], p=0.003). Pre- and postoperative NT-proBNP concentrations were closely correlated (rho=0.80, p<0.001) and postoperative NT-proBNP concentrations were also associated with long-term mortality after adjustment for EuroSCORE II. A parsimonious risk model that included age, creatinine clearance, chronic pulmonary disease, and NT-proBNP measurements provided comparable prognostic accuracy as EuroSCORE II in cohort #1 and #2 for risk of long-term mortality. hs-TnT measurements did not add to NT-proBNP measurements CONCLUSION: NT-proBNP measurements could improve and simplify risk prediction in cardiac surgical patients.

Decreased maximum clot firmness in rotational thromboelastometry (ROTEM®) is associated with bleeding during extracorporeal mechanical circulatory support.

BACKGROUND:: We aimed to characterize the coagulation disturbances which may increase the risk of bleeding, thrombosis or death shortly after implantation of an extracorporeal membrane oxygenation (ECMO) or ventricular assist (VAD) device. METHODS:: Antithrombotic treatment was started in 23 VAD and 24 ECMO patients according to the hospital protocol. Additionally, conventional laboratory testing, rotational thromboelastometry (ROTEM®) and platelet function analysis (Multiplate®) were performed at predetermined intervals. RESULTS:: Four out of twenty-four (16.7%) of ECMO patients and 6/23 (26.1%) of VAD patients had severe bleeding after the procedure. When all the patients were analyzed together, low maximum clot firmness (MCF) in ExTEM and FibTEM analyses was associated with severe bleeding (p<0.05) and low MCF in FibTEM with 30-day mortality. Low platelet count and hematocrit levels were also associated with severe bleeding. When VAD and ECMO patients were separated into different groups, the association between ROTEM® parameters, bleeding and survival was found only in limited time points. Four patients with VAD had cerebral ischemia indicative of thromboembolism. However, this had no significant correlation with ROTEM® or Multiplate® parameters. CONCLUSION:: Hypocoagulation shown by ROTEM® was associated with bleeding complications in patients with mechanical circulatory support. In contrast, hypercoagulation did not correlate with clinical thrombosis.

Cancer among circumpolar populations: an emerging public health concern.

OBJECTIVES: To determine and compare the incidence of cancer among the 8 Arctic States and their northern regions, with special focus on 3 cross-national indigenous groups--Inuit, Athabaskan Indians and Sami. METHODS: Data were extracted from national and regional statistical agencies and cancer registries, with direct age-standardization of rates to the world standard population. For comparison, the "world average" rates as reported in the GLOBOCAN database were used. FINDINGS: Age-standardized incidence rates by cancer sites were computed for the 8 Arctic States and 20 of their northern regions, averaged over the decade 2000-2009. Cancer of the lung and colon/rectum in both sexes are the commonest in most populations. We combined the Inuit from Alaska, Northwest Territories, Nunavut and Greenland into a "Circumpolar Inuit" group and tracked cancer trends over four 5-year periods from 1989 to 2008. There has been marked increase in lung, colorectal and female breast cancers, while cervical cancer has declined. Compared to the GLOBOCAN world average, Inuit are at extreme high risk for lung and colorectal cancer, and also certain rare cancers such as nasopharyngeal cancer. Athabaskans (from Alaska and Northwest Territories) share some similarities with the Inuit but they are at higher risk for prostate and breast cancer relative to the world average. Among the Sami, published data from 3 cohorts in Norway, Sweden and Finland show generally lower risk of cancer than non-Sami. CONCLUSIONS: Cancer among certain indigenous people in the Arctic is an increasing public health concern, especially lung and colorectal cancer.

Clinical Durability of the CARMEDA BioActive Surface in EXCOR Ventricular Assist Device Pumps.

The durability of CBAS Heparin Surface on EXCOR pumps retrieved after clinical use for varying periods of time was studied by analyzing samples for surface heparin density and bioactivity. The mean time of clinical use of the investigated 14 EXCOR pumps was 178 days (range, 15-461 days). Mean heparin density was 3.1 ± 0.6 µg/cm² (range, 2.2-4.8 µg/cm²), and the measured mean heparin bioactivity was 14 ± 5 ρmol/cm² (range: 7-27 ρmol/cm²). There was no detectable degradation or loss of function of CBAS Heparin Surface over time. Samples from the housing and the membrane of the EXCOR pump showed no significant difference in heparin bioactivity or density. The CBAS Heparin Surface stays on the surface and remains bioactive on the EXCOR pump at least up until 1 year. This is an important demonstration of coating durability and supports the mid-term and long-term clinical use as bridge-to-heart transplantation or to myocardial recovery.

Suicide in circumpolar regions: an introduction and overview.

This extended editorial introduces the Special Issue on Suicide and Resilience in Circumpolar Regions, the results of the knowledge synthesis project by an international research team funded by the Canadian Institutes of Health Research and endorsed by the Arctic Council. It focuses on the extent and magnitude of the problem of suicidal behaviours and thoughts from a circumpolar perspective - the variation across Arctic States and their northern regions, the excess risk among some indigenous groups and their demographic characteristics. Much remains to be learned about the design and implementation of youth-focused intervention programmes, especially in a circumpolar comparative framework.

Survival of Sami cancer patients.

OBJECTIVES: The incidence of cancer among the indigenous Sami people of Northern Finland is lower than among the Finnish general population. The survival of Sami cancer patients is not known, and therefore it is the object of this study. STUDY DESIGN: The cohort consisted of 2,091 Sami and 4,161 non-Sami who lived on 31 December 1978 in the two Sami municipalities of Inari and Utsjoki, which are located in Northern Finland and are 300-500 km away from the nearest central hospital. The survival experience of Sami and non-Sami cancer patients diagnosed in this cohort during 1979-2009 was compared with that of the Finnish patients outside the cohort. METHODS: The Sami and non-Sami cancer patients were matched to other Finnish cancer patients for gender, age and year of diagnosis and for the site of cancer. An additional matching was done for the stage at diagnosis. Cancer-specific survival analyses were made using the Kaplan-Meier method and Cox regression modelling. RESULTS: There were 204 Sami and 391 non-Sami cancer cases in the cohort, 20,181 matched controls without matching with stage, and 7,874 stage-matched controls. In the cancer-specific analysis without stage variable, the hazard ratio for Sami was 1.05 (95% confidence interval 0.85-1.30) and for non-Sami 1.02 (0.86-1.20), indicating no difference between the survival of those groups and other patients in Finland. Likewise, when the same was done by also matching the stage, there was no difference in cancer survival. CONCLUSION: Long distances to medical care or Sami ethnicity have no influence on the cancer patient survival in Northern Finland.

Mortality of the Sami in northern Finland 1979-2005.

OBJECTIVES: To describe the mortality of the Finnish Sami population. Study design. A cohort study. The Sami population living in northern Finland represents a specific genetic background and a way of life that has been different from other Finns. METHODS: A cohort of all 2091 Sami and 4,161 non-Sami people from the 2 northernmost municipalities of Finland on 31 December 1978 was identified from the National Population Register and followed up for their mortality during 1979-2005. RESULTS: Altogether 625 Sami died during 1979-2005, while the expected number based on the average mortality rates in the entire Finnish population was 633. The standardized mortality ratio (SMR) of the Sami population was 0.99 (95% confidence interval 0.91-1.06), and for the non-Sami 1.07 (1.00-1.14). The mortality from accidents and violence was elevated both among the Sami, SMR 1.67 (1.32-2.08), and among the non-Sami, 1.28 (1.04-1.53). Snowmobile and water transport accidents were especially common. SMR for disease mortality among the Sami men was 0.88 (0.78-0.98). Half of the decrease was attributable to the low mortality from cancer, SMR 0.69 (0.52-0.90). SMR for circulatory diseases was very similar. The SMRs for dementia and Alzheimer's disease were elevated among the Sami men. CONCLUSIONS: The Sami men had a lower disease mortality as compared with the Finnish population generally and their non-Sami neighbours, although their life habits would suggest a higher mortality rate. Reasons for their lower mortality may be related to their diet that is rich in reindeer meat and fish, their physically active way of life or their genetic background.

Cancer among the Sami--a review on the Norwegian, Swedish and Finnish Sami populations.

OBJECTIVES: The Sami are the Indigenous people of the northernmost parts of Sweden, Finland and Norway, and of the Kola Peninsula of Russia. The present review summarizes the main results from studies on cancer morbidity and mortality among the Sami and discusses these results in relation to exposure of known risk factors. STUDY DESIGN: Literature review. METHODS: A systematic search over the time period 1966-2008 for relevant articles was conducted on MEDLINE. Updates and recalculations of some of the results from the original data were also done. RESULTS: Nine articles whose main focus is on cancer incidence or mortality among the Sami were identified. In all studies, the overall incidence of cancer or cancer mortality was lower among the Sami in comparison with the national populations. The differences were less striking in relation to regional reference populations, but the rates were still significantly lower for all populations of Sami, except for Swedish Sami women. Beyond the general trend of a lower cancer incidence among the Sami, there were some notable differences between the various Sami subpopulations. CONCLUSIONS: The risk of developing and dying from cancer is low among the Sami. A life-style that includes cancer-protective factors, such as certain dietary components and physical activity, is the most likely explanation for the lower incidence of cancer among the Sami.

Cancer incidence among Sami in Northern Finland, 1979-1998.

The Sami population living in Northern Finland represents a specific genetic background and a way of life that is different from other Finns. A cohort of 2,100 Sami and 4,174 non-Sami people from the 2 northernmost municipalities of Finland on 31 December 1978 was identified from the national Population Register and followed up through the Finnish Cancer Registry for cancer incidence during 1979-1998. There were 111 cancer cases among the Sami, while the expected number based on the average cancer incidence in the Finnish population was 173. Among the non-Sami cohort members, there were 226 cases of cancer vs. 224 expected cases. The Sami had significantly decreased incidence of cancers of the prostate [standardised incidence ratio (SIR) 0.25; 95% confidence interval (CI) 0.08-0.58] and breast (SIR 0.36; 95% CI 0.14-0.73), similarly for both localised and nonlocalised tumours. Low SIRs were also observed for bladder cancer (SIR 0.28; 97% CI 0.03-0.99) basal cell carcinoma of the skin (SIR 0.12; 95% CI 0.03-0.30) and other nonmelanoma skin cancers (SIR 0; 95% CI 0-0.63). In contrast to other subcategories of the Sami, the Skolts, whose lifestyle stems from areas that now belong to Russia, showed a nonreduced overall cancer risk and a significantly elevated risk for stomach cancer (SIR 3.8; 95% CI 1.5-7.8). The low cancer incidence among the other Sami populations in Finland cannot be fully explained by their specific way of life. It seems likely that the Sami ethnicity carries a reduced cancer incidence level. Although many Sami have been exposed to radioactive fallout from the nuclear weapon tests via their reindeer-rich diet, this does not seem to affect their cancer risk.
