Developing a multivariable prediction model of global health-related quality of life in patients treated for rectal cancer: a prospective study in five countries.

PURPOSE: Rectal cancer and its treatment have a negative impact on health-related quality of life (HRQoL). If risk factors for sustained low HRQoL could be identified early, ideally before the start of treatment, individualised interventions could be identified and implemented to maintain or improve HRQoL. The study aimed to develop a multivariable prediction model for global HRQoL 12 months after rectal cancer treatment. METHODS: Within COLOR II, a randomised, multicentre, international trial of laparoscopic and open surgery for rectal cancer, a sub-study on HRQoL included 385 patients in 12 hospitals and five countries. The HRQoL study was optional for hospitals in the COLOR II trial. EORTC QLQ-C30 and EORTC QLQ-CR38 were analysed preoperatively and at 1 and 12 months postoperatively. In exploratory analyses, correlations between age, sex, fatigue, pain, ASA classification, complications, and symptoms after surgery to HRQoL were studied. Bivariate initial analyses were followed by multivariate regression models. RESULTS: Patient characteristics and clinical factors explained 4-10% of the variation in global HRQoL. The patient-reported outcomes from EORTC QLQ-C30 explained 55-65% of the variation in global HRQoL. The predominant predictors were fatigue and pain, which significantly impacted global HRQoL at all time points measured. CONCLUSION: We found that fatigue and pain were two significant factors associated with posttreatment global HRQoL in patients treated for rectal cancer T1-T3 Nx. Interventions to reduce fatigue and pain could enhance global HRQoL after rectal cancer treatment. TRIAL REGISTRATION: This trial is registered with ClinicalTrials.gov No. NCT00297791.

Are patients willing to take a more active role? Questionnaires to measure patients' willingness to be empowered.

OBJECTIVE: One crucial prerequisite for increased patient empowerment is the willingness among patients to take a more active role. The aim of this study was to develop questionnaires for measuring a patient's willingness to be empowered in general and by using e-health. METHODS: The study was based on a random sample from an online panel. The 800 responders were Swedish citizens and reflected the internet-using population in Sweden regarding age, gender, income, and education. The measurement properties were evaluated according to the Rasch Measurement Theory. RESULTS: The analyses showed two questionnaires with adequate fit to the basic measurement model and with high reliability (PSI 0.84 and 0.89, respectively). CONCLUSION: We conclude that this study generated two questionnaires with an intuitive order of items illustrating an understandable progression of willingness to be empowered in general as well as for e-health. PRACTICE IMPLICATIONS: The suggested questionnaires are valuable tools supporting the effort to tailor empowerment strategies to meet the patient's willingness. Questionnaires will also be valuable for evaluating strategies for supporting willingness, studying factors related to willingness and potential inequalities due to e.g. varying digital literacy, and for enabling identification of patient stereotypes using cluster analyses.

Online Communities as a Driver for Patient Empowerment: Systematic Review.

BACKGROUND: The use of online resources has changed how people manage health care processes. Patients seek information about health conditions, guidance in treatment, and support from peers online, complementary to traditional health care trajectories. Online communities have the potential to contribute to the quality of care by increasing patient empowerment; however, there is a gap in research regarding in what way online communities contribute to patient empowerment. OBJECTIVE: We synthesized research regarding how online communities contribute to patient empowerment to address the research question "In what ways can participation in online communities support patient empowerment?" by studying how patient empowerment is operationalized in different studies. The definition of patient empowerment used in this paper is enablement for people to develop mastery over actions and control over decisions that influence their lives. The mastery is both through processes and outcomes of the development. METHODS: A systematic review was conducted by searching in the following databases: Scopus, ACM Digital Library, EBSCO (CINAHL and MEDLINE), PubMed, and Web of Science. In total, there were 1187 papers after excluding duplicates, and through selection processes using an analytical framework with definitions of patient empowerment and related concepts, 33 peer-reviewed papers were included. RESULTS: Findings indicated that online communities support patient empowerment both as a process and as outcomes of these processes. Additionally, it was seen as a complement to traditional health care and encouragement for health care professionals to have a more positive attitude toward patients' usage. There was a mix between deductive (19/33, 58%), inductive (11/33, 33%), and a mixed approach (3/33, 9%) of studying patient empowerment in various forms. The online communities in most papers (21/33, 64%) were well-established and represented patients' initiatives. CONCLUSIONS: There is a need to include professionals' perspectives regarding how health care can embrace patient empowerment through online communities. This systematic review's main contribution is the proposal of a new framework and conceptualization of how patient empowerment in online communities can be understood from different hierarchical levels.

Individualized blended care for patients with colorectal cancer: the patient's view on informational support.

PURPOSE: The number of colorectal cancer patient survivors is increasing. Information and support during and after treatment are requested by patients, but questions remain on what to provide. The aim of this study was to understand what informational needs colorectal cancer patients and survivors have, with a focus on the potential support given by patient peers and the use of blended care. METHODS: A qualitative study using focus groups was conducted with patients diagnosed at the same hospital at least one year prior to the initiation of the study. The focus group interviews were transcribed verbatim and analyzed using deductive content analysis. RESULTS: The need for informational support varied over time and depended on individual patient characteristics. Timing was crucial and patients requested options of blended care and informational support after treatment cessation. The patients felt alone after treatment and requested assistance in communication with their next-of-kin. They also identified the value of peer support, especially to contextualize knowledge provided by healthcare. CONCLUSION: This study showed a need for focus on individualized informational support. Blended care through integrating communication with peers online could be one way to support patients, both to enable shared decision-making as well as to provide person-centered care.

Digitalization and Physician Learning: Individual Practice, Organizational Context, and Social Norm.

INTRODUCTION: The emerging context of online platforms and digitally engaged patients demands new competencies of health care professionals. Although information and communication technologies (ICTs) can strengthen continuous professional development (CPD) and learning at work, more research is needed on ICT for experiential and collegial learning. METHODS: The study builds on prior qualitative research to identify issues and comprises a quantitative assessment of ICT usage for learning in health care. A survey was administered to Swedish physicians participating in a CPD program as part of specialist medical training. Conclusions focused specifically on learning dimensions are drawn from correlation analyses complemented with multiple regression. RESULTS: The findings show that physicians' actual use of ICT is related to perceived performance, social influence, and organizational context. Social norm was the most important variable for measured general usage, whereas performance expectancy (perceived usefulness of ICT) was important for ICT usage for learning. The degree of individual digitalization affects performance and, in turn, actual use. DISCUSSION: The study highlights the need to incorporate ICT effectively into CPD and clinical work. Besides formal training and support for specific systems, there is a need to understand the usefulness of digitalization integrated into practice. Moving beyond instrumentalist views of technology, the model in this study includes contextualized dimensions of ICT and learning in health care. Findings confirm that medical communities are influencers of use, which suggests that an emphasis on collegial expectations for digital collaboration will enhance practitioner adaptation.

Flipped healthcare for better or worse.

The medical profession is highly specialized, demanding continuous learning, while also undergoing rapid development in the rise of data-driven healthcare. Based on clinical scenarios, this study explores how resident physicians view their roles and practices in relation to informed patients and patient-centric digital technologies. The paper illustrates how the new role of patients alters physicians' work and use of data to learn and update their professional practice. It suggests new possibilities for developing collegial competence and using patient experiences more systematically. Drawing on the notion of flipped healthcare, we argue that there is a need for new professional competencies in everyday data work, along with a change in attitudes, newly defined roles, and better ways to identify and develop reliable online sources. Finally, the role of patients, not only as consumers but also producers of healthcare, is a rather formidable and complex cultural change to be addressed.

A national study on collaboration in care planning for patients with complex needs.

INTRODUCTION: The purpose of this study was to investigate inter-organisational collaboration on care planning for patients with complex care needs. Internationally, and in Sweden where the data for this study was collected, difficulties in care planning and transition of patients between the main health care providers, hospitals, municipal care, and primary care are well known. METHOD: A survey of a total population of care managers in hospitals, municipalities, and primary care in Sweden was conducted. The study assessed accessibility, willingness, trustworthiness, and collaboration between health care providers. Data were analysed with descriptive statistics, bivariate, and multivariate regressions. RESULTS: The results indicate that Swedish health care providers show strong self-awareness, but they describe each other's ability to collaborate as weak. Primary care stands out, displaying the highest discrepancy between self-awareness and displayed accessibility, willingness, trustworthiness, and collaboration. CONCLUSION: Inability to collaborate in patient care planning may be due to shortcomings in terms of trust between caregivers in the health care organisation at a national level. Organisations that experience difficulties in collaboration tend to defend themselves with arguments about their own excellence and insufficiency of others.

Protocol for a randomised controlled trial to study cryoprevention of chemotherapy-induced oral mucositis after autologous stem cell transplantation.

INTRODUCTION: A majority of patients who receive myeloablative therapy prior to hematopoetic stem cell transplantation develop oral mucositis (OM). This adverse cytotoxic effect manifests as oral mucosal erythema and ulcerations and frequently necessitates high doses of morphine for pain alleviation. OM may also interfere with food intake and result in parenteral nutrition, weight loss and impaired quality of life. To date, there have been a few studies of evidence-based interventions for prevention of OM. Cooling the oral mucosa using ice chips in conjunction with chemotherapy is known to reduce the severity of OM although clinical application is still limited due to several disadvantages. The primary endpoint of this study is therefore to evaluate the efficacy of an innovative intraoral cooling device (Cooral) compared with ice cooling in reducing the degree of OM, in patients with myeloma or lymphoma. METHOD AND ANALYSIS: A total of 180 patients from four different university hospitals in Sweden will be randomised to ice or Cooral in a proportion of 1:1. The degree of OM will be assessed at eight intraoral locations, in accordance with the Oral Mucositis Assessment Scale and WHO scale. Patients will be registered beginning at admission and will continue until discharge or until day +28. The primary variable is analysed in a multiple linear regression model. The significance level used is 5%. ETHICS AND DISSEMINATION: The study protocol, questionnaire, diaries and letter of invitation to participants have been reviewed by the local ethical board in Göteborg. The trial results will be published in a peer-reviewed journal and disseminated to participants. TRIAL REGISTRATION NUMBER: NCT03203733; Pre-results. PROTOCOL VERSION: Version 4, 2017-06-05.

A first step towards a model for teachers' adoption of ICT pedagogy in schools.

It is important to identify and understand important factors underpinning the integration of information and communication technology (ICT) in schools. And, it is important that ICT is adopted in a sound pedagogical manner. The aim with this study was to suggest a model for the actual use of ICT in schools and how it may be related to important factors such as technological pedagogical expectations. The design of the model was inspired by TAM2 and UTAUT models, but with some modifications. We have developed a model which highlight the pedagogical aspects beyond the technical ones. Furthermore, our suggested model also include the adoption of digital techniques in everyday life as a potential predictor of adoption of ICT at work. The sample consists of 122 teachers and we analyzed the model with a structural equation model. This study contributes with a suggested model including a new construct for measuring expected performance from a technological pedagogical point of view. This new construct was a significant predictor to actual use of ICT in school. Furthermore we also developed a new construct for adoption of ICT in everyday life, which also was a significant predictor to actual use of ICT in school.

The early chain of care in bacteraemia patients: Early suspicion, treatment and survival in prehospital emergency care.

INTRODUCTION: Bacteraemia is a first stage for patients risking conditions such as septic shock. The primary aim of this study is to describe factors in the early chain of care in bacteraemia, factors associated with increased chance of survival during the subsequent 28days after admission to hospital. Furthermore, the long-term outcome was assessed. METHODS: This study has a quantitative design based on data from Emergency Medical Services (EMS) and hospital records. RESULTS: In all, 961 patients were included in the study. Of these patients, 13.5% died during the first 28days. The EMS was more frequently used by non-survivors. Among patients who used the EMS, the suspicion of sepsis already on scene was more frequent in survivors. Similarly, EMS personnel noted the ESS code "fever, infection" more frequently for survivors upon arriving on scene. The delay time from call to the EMS and admission to hospital until start of antibiotics was similar in survivors and non-survivors. The five-year mortality rate was 50.8%. Five-year mortality was 62.6% among those who used the EMS and 29.5% among those who did not (p<0.0001). CONCLUSION: This study shows that among patients with bacteraemia who used the EMS, an early suspicion of sepsis or fever/infection was associated with improved early survival whereas the delay time from call to the EMS and admission to hospital until start of treatment with antibiotics was not. 50.8% of all patients were dead after five years.

Determination of age- and sex-specific 99th percentiles for high-sensitive troponin T from patients: an analytical imprecision- and partitioning-based approach.

BACKGROUND: Detection of acute myocardial infarction (AMI) is mainly based on a rise of cardiac troponin with at least one value above the 99th percentile upper reference limit (99th URL). However, circulating high-sensitive cardiac troponin T (hs-cTnT) concentrations depend on age, sex and renal function. Using an analytical imprecision-based approach, we aimed to determine age- and sex-specific hs-cTnT 99th URLs for patients without chronic kidney disease (CKD). METHODS: A 3.8-year retrospective analysis of a hospital laboratory database allowed the selection of adult patients with concomitant plasma hs-cTnT (<300 ng/L) and creatinine concentrations, both assayed twice within 72 h with at least 3 h between measurements. Absence of AMI was assumed when the variation between serial hs-cTnT values was below the adjusted-analytical change limit calculated according to the inverse polynomial regression of analytical imprecision. Specific URLs were determined using Clinical and Laboratory Standards Institute (CLSI) methods, and partitioning was tested using the proportion method, after adjustment for unequal prevalences. RESULTS: After outlier removal (men: 8.7%; women: 6.6%), 1414 men and 1082 women with estimated glomerular filtration rate (eGFR) ≥60 mL/min/1.73 m2 were assumed as non-AMI. Partitioning into age groups of 18-50, 51-70 and 71-98 years, the hs-cTnT 99th URLs adjusted on French prevalence were 18, 33, 66 and 16, 30, 84 ng/L for men and women, respectively. Age-partitioning was clearly required. However, sex-partitioning was not justified for subjects aged 18-50 and 51-70 years for whom a common hs-cTnT 99th URLs of about 17 and 31 ng/L could be used. CONCLUSIONS: Based on a laboratory approach, this study supports the need for age-specific hs-cTnT 99th URLs.

Correction to: Innovative intraoral cooling device better tolerated and equally effective as ice cooling.

Unfortunately, the online published article has error in Table 1. The correct Table 1 is given in the following page.

Innovative intraoral cooling device better tolerated and equally effective as ice cooling.

PURPOSE: Most of the patients who receive myeloablative therapy prior to stem cell transplantation develop oral mucositis (OM). This adverse reaction manifests as oral mucosal erythema and ulcerations and may require high doses of morphine for pain alleviation. OM may also interfere with food intake and result in weight loss, a need for parenteral nutrition, and impaired quality of life. To date, there have been very few studies of evidence-based interventions for the prevention of OM. Cryotherapy, using ice chips, has been shown to reduce in an efficient manner the severity and extent of OM, although clinical applications are still limited due to several shortcomings, such as adverse tooth sensations, problems with infectious organisms in the water, nausea, and uneven cooling of the oral mucosa. The present proof-of-concept study was conducted to compare the tolerability, temperature reduction, and cooling distribution profiles of an intra-oral cooling device and ice chips in healthy volunteers who did not receive myeloablative treatment, and therefore, did not experience the symptoms of OM. METHODS: Twenty healthy volunteers used the cooling device and ice chips for a maximum of 60 min each, using a cross-over design. The baseline and final temperatures were measured at eight intra-oral locations using an infra-red thermographic camera. The thermographic images were analysed using two digital software packages. A questionnaire was used to assess the tolerability levels of the two interventions. RESULTS: The intra-oral cooling device was significantly better tolerated than the ice-chips (p = 0.0118). The two interventions were equally effective regarding temperature reduction and cooling distribution. CONCLUSIONS: The intra-oral cooling device shows superior tolerability in healthy volunteers. Furthermore, this study shows that temperature reduction and cooling distribution are achieved equally well using either method.

Association between use of pre-hospital ECG and 30-day mortality: A large cohort study of patients experiencing chest pain.

BACKGROUND: In the assessment of patients with chest pain, there is support for the use of pre-hospital ECG in the literature and in the care guidelines. Using propensity score methods, we aim to examine whether the mere acquisition of a pre-hospital ECG among patients with chest pain affects the outcome (30-day mortality). METHODS: The association between pre-hospital ECG and 30-day mortality was studied in the overall cohort (n=13151), as well as in the one-to-one matched cohort with 2524 patients not examined with pre-hospital ECG and 2524 patients examined with pre-hospital ECG. RESULTS: In the overall cohort, 21% (n=2809) did not undergo an ECG tracing in the pre-hospital setting. Among those who had pain during transport, 14% (n=1159) did not undergo a pre-hospital ECG while 32% (n=1135) of those who did not have pain underwent an ECG tracing. In the overall cohort, the OR for 30-day mortality in patients who had a pre-hospital ECG, as compared with those who did not, was 0.63 (95% CI 0.05-0.79; p<0.001). In the matched cohort, the OR was 0.65 (95% CI 0.49-0.85; p<0.001). Using the propensity score, in the overall cohort, the corresponding HR was 0.65 (95% CI 0.58-0.74). CONCLUSION: Using propensity score methods, we provide real-world data demonstrating that the adjusted risk of death was considerably lower among the cases in whoma pre-hospital ECG was used. The PH-ECG is underused among patients with chest discomfort and the mere acquisition of a pre-hospital ECG may reduce mortality.

Emergency medical dispatch priority in chest pain patients due to life threatening conditions: A cohort study examining circadian variations and impact of the education.

BACKGROUND AND AIMS: We examined the accuracy in assessments of emergency dispatchers according to their education and time of the day. We examined this in chest pain patients who were diagnosed with a potentially life-threatening condition (LTC) or died within 30days. METHODS: Among 2205 persons, 482 died, 1631 experienced an acute coronary syndrome (ACS), 1914 had a LTC. Multivariable logistic regression was used to study how time of the call and the dispatcher's education were associated with the risk of missing to give priority 1 (the highest). RESULTS: Among patients who died, a 7-fold increase in odds of missing to give priority 1 was noted at 1.00pm, as compared with midnight. Compared with assistant nurses, odds ratio for dispatchers with no (medical) training was 0.34 (95% CI 0.14 to 0.77). Among patients with an ACS, odds ratio for calls arriving before lunch was 2.02 (95% CI 1.22 to 3.43), compared with midnight. Compared with assistant nurses, odds ratio for operators with no training was 0.23 (95% CI 0.13 to 0.40). Similar associations were noted for those with any LTC. Dispatcher's education was not associated with the patient's survival. CONCLUSIONS: In this group of patients, which experience substantial mortality and morbidity, the risk of not obtaining highest dispatch priority was increased up to 7-fold during lunchtime. Dispatch operators without medical education had the lowest risk, compared with nurses and assistant nurses, of missing to give priority 1, at the expense of lower positive predictive value. KEY MESSAGES: What is already known about this subject? Use of the emergency medical service (EMS) increases survival among patients with acute coronary syndromes. It is unknown whether the efficiency - as judged by the ability to identify life-threatening cases among patients with chest pain - varies according to the dispatcher's educational level and the time of day. What does this study add? We provide evidence that the dispatcher's education does not influence survival among patients calling the EMS due to chest discomfort. However, medically educated dispatchers are at greatest risk of missing to identify life-threatening cases, which is explained by more parsimonious use of the highest dispatch priority. We also show that the risk of missing life-threatening cases is at highest around lunch time. How might this impact on clinical practice? Dispatch centers are operated differently all over the world and chest discomfort is one of the most frequent symptoms encountered; we provide evidence that it is safe to operate a dispatch center without medically trained personnel, who actually miss fewer cases of acute coronary syndromes. However, non-medically trained dispatchers consume more pre-hospital resources.

Could prioritisation by emergency medicine dispatchers be improved by using computer-based decision support? A cohort of patients with chest pain.

BACKGROUND: To evaluate whether a computer-based decision support system could improve the allocation of patients with acute coronary syndrome (ACS) or a life-threatening condition (LTC). We hypothesised that a system of this kind would improve sensitivity without compromising specificity. METHODS: A total of 2285 consecutive patients who dialed 112 due to chest pain were asked 10 specific questions and a prediction model was constructed based on the answers. We compared the sensitivity of the dispatchers' decisions with that of the model-based decision support model. RESULTS: A total of 2048 patients answered all 10 questions. Among the 235 patients with ACS, 194 were allocated the highest prioritisation by dispatchers (sensitivity 82.6%) and 41 patients were given a lower prioritisation (17.4% false negatives). The allocation suggested by the model used the highest prioritisation in 212 of the patients with ACS (sensitivity of 90.2%), while 23 patients were underprioritised (9.8% false negatives). The results were similar when the two systems were compared with regard to LTC and 30-day mortality. This indicates that computer-based decision support could be used either for increasing sensitivity or for saving resources. Three questions proved to be most important in terms of predicting ACS/LTC, [1] the intensity of pain, [2] the localisation of pain and [3] a history of ACS. CONCLUSION: Among patients with acute chest pain, computer-based decision support with a model based on a few fundamental questions could improve sensitivity and reduce the number of cases with the highest prioritisation without endangering the patients.

The Early Chain of Care in Patients with Bacteraemia with the Emphasis on the Prehospital Setting.

UNLABELLED: Purpose There is a lack of knowledge about the early phase of severe infection. This report describes the early chain of care in bacteraemia as follows: (a) compare patients who were and were not transported by the Emergency Medical Services (EMS); (b) describe various aspects of the EMS chain; and (c) describe factors of importance for the delay to the start of intravenous antibiotics. It was hypothesized that, for patients with suspected sepsis judged by the EMS clinician, the delay until the onset of antibiotic treatment would be shorter. Basic Procedures All patients in the Municipality of Gothenburg (Sweden) with a positive blood culture, when assessed at the Laboratory of Bacteriology in the Municipality of Gothenburg, from February 1 through April 30, 2012 took part in the survey. Main Findings/Results In all, 696 patients fulfilled the inclusion criteria. Their mean age was 76 years and 52% were men. Of all patients, 308 (44%) had been in contact with the EMS and/or the emergency department (ED). Of these 308 patients, 232 (75%) were transported by the EMS and 188 (61%) had "true pathogens" in blood cultures. Patients who were transported by the EMS were older, included more men, and suffered from more severe symptoms and signs. The EMS nurse suspected sepsis in only six percent of the cases. These patients had a delay from arrival at hospital until the start of antibiotics of one hour and 19 minutes versus three hours and 21 minutes among the remaining patients (P =.0006). The corresponding figures for cases with "true pathogens" were one hour and 19 minutes versus three hours and 15 minutes (P =.009). CONCLUSION: Among patients with bacteraemia, 75% used the EMS, and these patients were older, included more men, and suffered from more severe symptoms and signs. The EMS nurse suspected sepsis in six percent of cases. Regardless of whether or not patients with true pathogens were isolated, a suspicion of sepsis by the EMS clinician at the scene was associated with a shorter delay to the start of antibiotic treatment.

Is preoperative physical activity related to post-surgery recovery?-a cohort study of colorectal cancer patients.

INTRODUCTION: An increasing interest is seen in the role of preoperative physical activity (PA) in enhancing postoperative recovery. The short-term effect of preoperative PA on recovery after colorectal cancer is unknown. The aim of this study was to evaluate the association of the preoperative level of PA with postoperative recovery after surgery due to colorectal cancer disease. METHODS: This is a prospective observational cohort study, with 115 patients scheduled to undergo elective colorectal surgery. The self-reported level of preoperative PA was compared to measures of recovery. RESULTS: Regular self-reported preoperative PA was associated with a higher chance of feeling highly physically recovered 3 weeks after surgery (relative chance 3.3, p = 0.038), compared to physical inactivity. No statistically significant associations were seen with length of hospital stay, self-assessed mental recovery, re-admittances or with re-operations. DISCUSSION: In clinical practice, evaluating the patients' level of PA is feasible and may potentially be used as a prognostic tool for patients undergoing colorectal cancer surgery. Given the study design, the results from this study cannot prove causality. CONCLUSION: The present study found that the preoperative level of PA was associated with a faster self-assessed physical recovery after colorectal cancer surgery. PA did not show any associations with the primary outcome measure length of hospital stay or any of the other secondary outcome measures. Assessment of PA level preoperatively could be used for prognostic reasons. If systematic preoperative/postoperative physical training will enhance recovery, this remains to be studied in a randomized controlled study. HIGHLIGHTS: We examined preoperative physical activity and the recovery after colorectal cancer surgery. Physically active individuals had faster self-assessed physical recovery. Assessment of preoperative physical activity may provide prognostic clinical information.

Could ten questions asked by the dispatch center predict the outcome for patients with chest discomfort?

BACKGROUND AND AIMS: From 2009 to 2010, approximately 14,000 consecutive persons who called for the EMS due to chest discomfort were registered. From the seventh month, dispatchers ask 2285 patient ten pre-specified questions. We evaluate which of these questions was independently able to predict an acute coronary syndrome (ACS), life-threatening condition (LTC) and death. METHODS: The questions asked mainly dealt with previous history and type of symptoms, each with yes/no answers. The dispatcher took a decision on priority; 1) immediately with sirens/blue light; 2) EMS on the scene within 30min; 3) normal waiting time.We examined the relationship between the answers to these questions and subsequent dispatch priority, as well as outcome, in terms of ACS, LTC and all-cause mortality. RESULTS: 2285 patients (mean age 67years, 49% women) took part, of which 12% had a final diagnosis of ACS and 15% had a LTC. There was a significant relationship between all the ten questions and the priority given by dispatchers. Localisation of the discomfort to the center of the chest, more intensive pain, history of angina or myocardial infarction as well as experience of cold sweat were the most important predictors when evaluating the probability of ACS and LTC. Not breathing normally and having diabetes were related to 30-day mortality. CONCLUSIONS: Among individuals, who call for the EMS due to chest discomfort, the intensity and the localisation of the pain, as well as a history of ischemic heart disease, appeared to be the most strongly associated with outcome.
