RESUMO

OBJECTIVE: To describe the development over time of the use of C-reactive protein (CRP) and rapid streptococcal detection test (RADT) point-of-care tests (POCT) in Danish general practice and to explore associations between patient characteristics and POCT use (i.e. CRP and RADT). DESIGN AND SETTINGS: A register-based study including all general practice clinic consultations in daytime and out-of-hours (OOH) settings in Denmark between 2003 and 2018. SUBJECTS: All citizens who had at least one clinic consultation in daytime or OOH general practice within the study period. MAIN OUTCOME MEASURES: We estimated the total and relative use of CRP and RADT POCTs and described the development over time. Crude and adjusted proportion ratios (PRs) were calculated to explore associations between patient characteristics and POCT use. RESULTS: Overall, the relative use of CRP POCTs increased. At OOH, a steep increase was noticed around 2012. The relative use of RADT decreased. Patient age 40-59 years and existing comorbidity were significantly associated with a higher use of CRP testing in both settings. A significantly lower use of CRP testing was found for patients with higher educational level. We found a significantly higher use of RADT testing for patients aged 0-19 years and with higher household educational level, whereas comorbidity was associated with a lower use of RADT testing. CONCLUSION: The use of CRP POCT increased over time, whereas the use of RADT POCT decreased. Perhaps the success of implementing CRP as a tool for reducing antibiotic use has reached it limit. Future studies should focus on how and when POCT are used most optimal.Key pointsCRP POC tests and RADT POCTs are frequently used diagnostic tools in general practice, both in daytime and in the out-of-hours setting.There was an increased use of CRP POCTs, particularly in out-of-hours general practice, whereas the use of RADT POCTs declined between 2003 and 2018.CRP POCTs were associated with age of 40-59 years and co-morbidity, while the use of RADT was mostly associated with younger age.

RESUMO

In the frame of the global phosphorus (P) crisis and ongoing eutrophication issues in the environmental sector, lake sediment can be considered as an alternative P source after its removal from eutrophic lakes. However, high water contents make sediment dewatering a crucial step towards the efficient reusability of remaining solids. The application of polymeric substances facilitates solid-liquid separation by flocculation of suspended particles. To lower the environmental risk of contamination with toxic, non-biodegradable monomeric residues during and after the application of synthetic polyacrylamide(PAM)-based polymers, switching to natural polymeric substances (biopolymers), e.g., starch- or chitosan-based, is increasingly emphasized. The dewatering performance of four conventional PAM-based polymers was compared to two starch- and one chitosan-based biopolymer. Laboratory experiments were conducted to determine the dewatering rate, floc size and strength, and reject water quality. Biopolymers generally caused the formation of smaller but less shear-sensitive flocs, and lower P levels in the reject water compared to synthetic polymers. Dewatering performance was correlated to the most important functioning influencing polymer-specific properties intrinsic viscosity (polymer extension) and surface charge density (CD). Due to the high CD and low intrinsic viscosity of the biopolymers, electrostatic patch flocculation seems to be the favored flocculation mechanism, while for synthetic polymers bridging seems to be dominating. Solid-liquid separation technologies should be adjusted to the resulting floc size and structure, while surface CD and intrinsic viscosity are important properties for the choice of biopolymer. Overall, biopolymers can function as a more environmentally friendly alternative to synthetic products for lake sediment dewatering accompanied by the potential for P recovery.

RESUMO

Aim: Understanding the variation in community composition and species abundances (i.e., ß-diversity) is at the heart of community ecology. A common approach to examine ß-diversity is to evaluate directional variation in community composition by measuring the decay in the similarity among pairs of communities along spatial or environmental distance. We provide the first global synthesis of taxonomic and functional distance decay along spatial and environmental distance by analysing 148 datasets comprising different types of organisms and environments. Location: Global. Time period: 1990 to present. Major taxa studied: From diatoms to mammals. Method: We measured the strength of the decay using ranked Mantel tests (Mantel r) and the rate of distance decay as the slope of an exponential fit using generalized linear models. We used null models to test whether functional similarity decays faster or slower than expected given the taxonomic decay along the spatial and environmental distance. We also unveiled the factors driving the rate of decay across the datasets, including latitude, spatial extent, realm and organismal features. Results: Taxonomic distance decay was stronger than functional distance decay along both spatial and environmental distance. Functional distance decay was random given the taxonomic distance decay. The rate of taxonomic and functional spatial distance decay was fastest in the datasets from mid-latitudes. Overall, datasets covering larger spatial extents showed a lower rate of decay along spatial distance but a higher rate of decay along environmental distance. Marine ecosystems had the slowest rate of decay along environmental distances. Main conclusions: In general, taxonomic distance decay is a useful tool for biogeographical research because it reflects dispersal-related factors in addition to species responses to climatic and environmental variables. Moreover, functional distance decay might be a cost-effective option for investigating community changes in heterogeneous environments.

RESUMO

OBJECTIVES: To investigate the impact of the Danish stroke campaign, 1 year after initiation. MATERIALS & METHODS: The campaign ran in various media during 2019-2020. We performed a two-centre, repeated cross-sectional study in 2018 (before campaign) and again in 2020 based on data from structured interviews of patients and bystanders, medical records and the Danish Stroke Registry. Primary outcomes were patient delay and system delay. Patient delay is defined as the time from symptom onset until the first contact to a healthcare professional, whereas system delay is the time from this contact until arrival at the stroke centre. Secondary outcomes were primary emergency medical services (EMS) contact, arrival at a stroke centre within 3 h of symptom onset, initiation of reperfusion therapy and knowledge of ≥2 core symptoms of stroke. RESULTS: We included 852 patients with stroke or transient ischemic attack. Patient delay and system delay were a median of 166 min and 96 min before the campaign and were non-significantly reduced by 16 min (95% CI -128 to 97) and 7 min (95% CI -21 to 6) in the second period. We found no significant differences in the clinical outcomes. The knowledge of ≥2 core symptoms increased from 22% to 30% (OR 1.63; 95% CI 1.15 to 2.30) in patients and from 53% to 65% (OR 1.81; 95% CI 1.24 to 2.64) in bystanders. CONCLUSION: Patient delay, system delay and clinical outcomes remained relatively unchanged. However, the knowledge of core symptoms had improved 1 year after campaign initiation.

RESUMO

We present a sub-picosecond resolved investigation of the structural solvent reorganization and geminate recombination dynamics following 400 nm two-photon excitation and photodetachment of a valence p electron from the aqueous atomic solute, I-(aq). The measurements utilized time-resolved X-ray Absorption Near Edge Structure (TR-XANES) spectroscopy and X-ray Solution Scattering (TR-XSS) at the Linac Coherent Light Source x-ray free electron laser in a laser pump/x-ray probe experiment. The XANES measurements around the L1-edge of the generated nascent iodine atoms (I0) yield an average electron ejection distance from the iodine parent of 7.4 ± 1.5 Å with an excitation yield of about 1/3 of the 0.1M NaI aqueous solution. The kinetic traces of the XANES measurement are in agreement with a purely diffusion-driven geminate iodine-electron recombination model without the need for a long-lived (I0:e-) contact pair. Nonequilibrium classical molecular dynamics simulations indicate a delayed response of the caging H2O solvent shell and this is supported by the structural analysis of the XSS data: We identify a two-step process exhibiting a 0.1 ps delayed solvent shell reorganization time within the tight H-bond network and a 0.3 ps time constant for the mean iodine-oxygen distance changes. The results indicate that most of the reorganization can be explained classically by a transition from a hydrophilic cavity with a well-ordered first solvation shell (hydrogens pointing toward I-) to an expanded cavity around I0 with a more random orientation of the H2O molecules in a broadened first solvation shell.

RESUMO

OBJECTIVE: To investigate the correlation between having designated general practitioners (GPs) in residential care homes and the residents' number of contacts with primary care, number of hospital admissions and mortality. DESIGN: A retrospective register-based longitudinal study. SETTING: Forty-two care homes in Aarhus Municipality, Denmark. SUBJECTS: A total of 2376 care home residents in the period from 1 September 2016 to 31 December 2018. MAIN OUTCOME MEASURES: We used two models to calculate the incidence risk ratio (IRR) for primary care contacts, hospital admission or dying. Model 1 compared the residents' risk time before with their risk time after implementation of the designated GP model. Model 2 included only risk time after implementation and was based on calculations of successful (rate ≥60%) implementation. RESULTS: Weighted by time at risk, the proportion of females across the two models ranged from 64% to 68%. The largest group was aged '85-94' years. In Model 1, the mere implementation of the model did not correlate with changes in primary care contacts, hospital admissions, or mortality. Contrarily, in Model 2, residents living in care homes with successful implementation had fewer email contacts (IRR = 0.81, 95%CI: 0.68;0.96), fewer telephone contacts (IRR = 0.78, 95%CI: 0.68;0.90) and fewer hospital admissions (IRR = 0.85, 95%CI: 0.73;0.99), but more home visits (IRR = 1.70, 95%CI: 1.29;2.25) than residents living in care homes with lower implementation rates. CONCLUSION: The designated GP model seems promising, as a high implementation degree of the model correlated with a reduced the number of acute admissions, short-term admissions and readmissions. Future studies should focus on gaining deeper insight into the mechanisms of the designated GP model to further optimize the model.Key pointsA new care model was introduced in Denmark in 2017, designating dedicated GPs to residential care homes for the elderly.Successful implementation correlated with significantly fewer hospital admissions, specifically for acute admissions, but also with fewer short-term admissions and readmissions.The implementation of the model correlated significantly with fewer e-mail and telephone contacts and with more home visits.Future studies should gain more insight into the mechanisms of the designated GP model to further optimize the model.

RESUMO

OBJECTIVE: To study variation in antibiotic prescribing rates among general practitioners (GP) in out-of-hours (OOH) primary care and to explore GP characteristics associated with these rates. DESIGN: Population-based observational registry study using routine data from the OOH primary care registration system on patient contacts and antibiotic prescriptions combined with national register data. SETTING: OOH primary care of the Central Denmark Region. SUBJECTS: All patient contacts in 2014-2017. MAIN OUTCOME MEASURES: GPs' tendency to prescribe antibiotics. Excess variation (not attributable to chance). RESULTS: We included 794,220 clinic consultations (16.1% with antibiotics prescription), 281,141 home visits (11.6% antibiotics), and 1,583,919 telephone consultations (5.8% antibiotics). The excess variation in the tendency to prescribe antibiotics was 1.56 for clinic consultations, 1.64 for telephone consultations, and 1.58 for home visits. Some GP characteristics were significantly correlated with a higher tendency to prescribe antibiotics, including 'activity level' (i.e. number of patients seen in the past hour) for clinic and telephone consultations, 'familiarity with OOH care' (i.e. number of OOH shifts in the past 180 days), male sex, and younger age for home visits. Overall, GP characteristics explained little of the antibiotic prescribing variation seen among GPs (Pseudo r2: 0.008-0.025). CONCLUSION: Some variation in the GPs' tendency to prescribe antibiotics was found for OOH primary care contacts. Available GP characteristics, such as GPs' activity level and familiarity with OOH care, explained only small parts of this variation. Future research should focus on identifying factors that can explain this variation, as this knowledge could be used for designing interventions.KEY POINTSCurrent awareness:Antibiotic prescribing rates seem to be higher in out-of-hours than in daytime primary care.Most important results:Antibiotic prescribing rates varied significantly among general practitioners after adjustment for contact- and patient-characteristics.This variation remained even after accounting for variation attributable to chance.General practitioners' activity level and familiarity with out-of-hours care were positively associated with their tendency to prescribe antibiotics.

RESUMO

We describe the distribution of prescriber types responsible for issuing prescriptions in Denmark. Using a 20% random sample of all Danes alive during 2000-2018 (n = 1 515 025) and all their prescriptions filled at community pharmacies (n = 182 143 707), we found that general practitioners issued 88% of all prescriptions, followed by hospital physicians (7.4%) and private practicing specialists (4.2%). These values were stable over the study period. With increasing patient age, general practitioners were responsible for a larger proportion of prescriptions (e.g. 68% for patients aged 0-17 y and 89% for patients ≥51 y). General practitioners were responsible for 84% of all treatment initiation (first prescription) and 90% of all maintenance treatment. Corresponding values for hospital physicians were 9.5 and 6.3%, and for private practicing specialists 5.3 and 3.6%. In conclusion, general practitioners are responsible for the vast majority of prescribing in Denmark, including both treatment initiation and continuation, in particular among the elderly.

RESUMO

OBJECTIVES: Prehospital delay is the main reason why only a limited number of stroke patients receive reperfusion therapy. We aimed to investigate help-seeking behaviour in patients and bystanders after onset of stroke and subsequent patient and system delay. MATERIALS & METHODS: We conducted a cross-sectional study of 332 patients with stroke. We performed structured interviews and used data from the medical records and the Danish Stroke Registry. Primary outcomes were patient delay and system delay. RESULTS: The median patient delay was 280 min, and the median system delay was 97 min. For a patient delay of <3 h, an additional non-significant system delay of median 30 min was seen for a first contact to a general practitioner (GP), and an additional significant delay of median 490 min was seen for the small group of patients with a first contact to 'other' healthcare professionals compared to the Emergency Medical Services (EMS). For a patient delay of more than 3 h, an additional system delay of median 78 min was found when the first contact was directed to the out-of-hours primary care (OOH-PC). A total of 17% of patients were admitted to another hospital or department before arrival at the stroke centre; this resulted in a substantially prolonged system delay of a median of 431 min. CONCLUSIONS: Patient delay remains the main reason for delayed arrival at the stroke centre. Appropriate help-seeking behaviour and efficient pre-hospital triage are essential for reducing the prehospital delay and increasing the proportion of patients receiving reperfusion therapy.

RESUMO

BACKGROUND: High demands create pressure on acute care services, such as emergency medical services (EMS), emergency departments (ED) and out-of-hours primary care (OOH-PC) services. A variety of patient- and organisational factors have been discussed as reasons why especially non-western migrants more frequently contact an ED or OOH-PC service than native born. We aim to investigate whether persons with a non-western and western migrant background more often contact an acute care service than native born and how this relates to the number of contacts with their general practitioners (GPs). In addition, we aim to explore how possible differences in acute care use by migrants can be explained. METHODS: We performed secondary analysis of data collected for the EurOOHnet survey on OOH help-seeking behaviour in Denmark, the Netherlands and Switzerland. Differences in self-reported acute care use (sum of number of contacts with OOH-PC, the ED and 1-1-2/1-4-4) between non-western and western migrants and native born were tested with a quasi Poisson regression analysis. Mediation analyses were performed to examine the impact of factors related to help-seeking on the relation between self-reported acute care use and migrant background. RESULTS: Non-western migrants had more acute care contacts than native born (adjusted IRR 1.74, 95% CI 1.33-2.25), whereas no differences were found between western migrants and native born. Migrants who regularly contacted OOH-PC or the ED also regularly contacted their GP. Mediation analyses showed that the factors employment, anxiety, attitude towards use of OOH-PC and problems in accessing the own GP could partly explain the higher acute care use of non-western migrants. CONCLUSION: The higher use of acute care services by non-western migrants compared with native born could partly be explained by feeling fewer barriers to contact these services, feeling more anxiety, more unemployment and problems making an appointment with the GP. Increasing awareness and improving GP access could help migrants in navigating the healthcare system.

RESUMO

High-temperature superconductivity emerges in many different quantum materials, often in regions of the phase diagram where the electronic kinetic energy is comparable to the electron-electron repulsion. Describing such intermediate-coupling regimes has proven challenging as standard perturbative approaches are inapplicable. Here, we employ quantum Monte Carlo methods to solve a multiband Hubbard model that does not suffer from the sign problem and in which only repulsive interband interactions are present. In contrast to previous sign-problem-free studies, we treat magnetic, superconducting, and charge degrees of freedom on an equal footing. We find an antiferromagnetic dome accompanied by a metal-to-insulator crossover line in the intermediate-coupling regime, with a smaller superconducting dome appearing in the metallic region. Across the antiferromagnetic dome, the magnetic fluctuations change from overdamped in the metallic region to propagating in the insulating region. Our findings shed new light on the intertwining between superconductivity, magnetism, and charge correlations in quantum materials.

RESUMO

BACKGROUND: In Western countries, patients with acute illness or injury out-of-hours (OOH) can call either emergency medical services (EMS) for emergencies or primary care services (OOH-PC) in less urgent situations. Callers initially choose which service to contact; whether this choice reflect the intended differences in urgency and severity is unknown. Hospital diagnoses and admission rates following an OOH service contact could elucidate this. We aimed to investigate and compare the prevalence of patient contacts, subsequent hospital contacts, and the age-related pattern of hospital diagnoses following an out-of-hours contact to EMS or OOH-PC services in Denmark. METHODS: Population-based observational cohort study including patients from two Danish regions with contact to EMS or OOH-PC in 2016. Hospital contacts were defined as short (< 24 h) or admissions (≥24 h) on the date of OOH service contact. Both regions have EMS, whereas the North Denmark Region has a general practitioner cooperative (GPC) as OOH-PC service and the Capital Region of Copenhagen the Medical Helpline 1813 (MH-1813), together representing all Danish OOH service types. Calling an OOH service is mandatory prior to a hospital contact outside office hours. RESULTS: OOH-PC handled 91% (1,107,297) of all contacts (1,219,963). Subsequent hospital contacts were most frequent for EMS contacts (46-54%) followed by MH-1813 (41%) and GPC contacts (9%). EMS had more admissions (52-56%) than OOH-PC. For both EMS and OOH-PC, short hospital contacts often concerned injuries (32-63%) and non-specific diagnoses (20-45%). The proportion of circulatory disease was almost twice as large following EMS (13-17%) compared to OOH-PC (7-9%) in admitted patients, whereas respiratory diseases (11-14%), injuries (15-22%) and non-specific symptoms (22-29%) were more equally distributed. Generally, admitted patients were older. CONCLUSIONS: EMS contacts were fewer, but with a higher percentage of hospital contacts, admissions and prevalence of circulatory diseases compared to OOH-PC, perhaps indicating that patients more often contact EMS in case of severe disease. However, hospital diagnoses only elucidate severity of diseases to some extent, and other measures of severity could be considered in future studies. Moreover, the socio-demographic pattern of patients calling OOH needs exploration as this may play an important role in choice of entrance.

RESUMO

OBJECTIVE: Demands for out-of-hours primary care (OOH-PC) services are increasing. Many citizens call because of non-urgent health problems. Nevertheless, the patients' motives for requesting medical help outside office hours remains an understudied area. This study aimed to examine motives for calling OOH-PC services in various age groups. DESIGN: Cross-sectional paper based questionnaire study conducted during two weeks in 2015. SETTING: The OOH-PC services in two Danish regions. SUBJECTS: Randomly selected patients calling the two healthcare services and accepting to participate in the study received a questionnaire on patient characteristics, health problems, and 26 pre-defined motives based on the Andersen Behavioural Model. Multivariate regression analyses were conducted for various age groups to calculate the probability of each motive to be a significant factor for the decision to call. RESULTS: A total of 1,871 patients were included in the study; half were parents of children aged 0-12 years. Young adults (18 to 39 years) differed significantly from other age groups as they more often stated perceived barriers and benefits such as "Own GP no time available soon enough" and "Need for quick help because of work". CONCLUSION: Young adults more often perceive barriers and benefits, which may suggest af difference in expectations regarding the purpose of out-of-hours services and accessibility. Further research is needed to address this issue and further explore the potential gap between the citizens' expectations to the OOH-PC services and the prevailing health policies. Key points The out-of-hours primary healthcare services are increasingly contacted for non-urgent problems, but little is known about the citizens' motives for calling. Age is associated with differences in the perceived importance of various motives for calling out-of-hours care. Young adults are more often than other age groups motivated to call due to logistical issues, such as their job.

RESUMO

BACKGROUND: Patients in need of acute health care do not always contact the most suitable health care service provider. Contacting out-of-hours primary care for an urgent problem may delay care, whereas contacting emergency medical services for a non-urgent problem could ultimately affect patient safety. More insight into patient motives for contacting a specific health care provider may help optimise patient flows. This study aims to explore patient motives for contacting out-of-hours primary care and the emergency medical services in Denmark. METHODS: We conducted a cross-sectional observational study by sending a questionnaire to patients contacting out-of-hours primary care and emergency medical services, both of which can be directly contacted by patients, in two of five Danish regions in 2015. As we aimed to focus on the first access point, the emergency department was not included. The questionnaire included items on patient characteristics, health problem and 26 pre-defined motives. Descriptive analyses of patient characteristics and motives were conducted, stratified by the two health care service providers. Factors associated with contacting each of the two service providers were explored in a modified Poisson regression analysis, and adjusted risk ratios were calculated. RESULTS: Three key motives for contacting the two service providers were identified: 'unpleasant symptoms', 'perceived need for prompt action' and 'perceived most suitable health care provider'. Other important motives were 'need arose outside office hours' and 'wanted to talk to a physician' (out-of-hours primary care) and 'expected need for ambulance' and 'worried' (emergency medical services). Higher probability of contacting the emergency medical services versus out-of-hours primary care was seen for most motives relating to own assessment and expectations, previous experience and knowledge, and own needs and wishes. Lower probability was seen for most motives relating to perceived barriers and benefits. CONCLUSIONS: Patient motives for contacting the two health care service providers were partly overlapping. The study contributes with new knowledge on the complex decision-making process of patients in need of acute health care. This knowledge could help optimise existing health care services, such as patient safety and the service level, without increasing health care costs.

RESUMO

Iron N-heterocyclic carbene (NHC) complexes have received a great deal of attention recently because of their growing potential as light sensitizers or photocatalysts. We present a sub-ps X-ray spectroscopy study of an FeII NHC complex that identifies and quantifies the states involved in the deactivation cascade after light absorption. Excited molecules relax back to the ground state along two pathways: After population of a hot 3 MLCT state, from the initially excited 1 MLCT state, 30 % of the molecules undergo ultrafast (150 fs) relaxation to the 3 MC state, in competition with vibrational relaxation and cooling to the relaxed 3 MLCT state. The relaxed 3 MLCT state then decays much more slowly (7.6 ps) to the 3 MC state. The 3 MC state is rapidly (2.2 ps) deactivated to the ground state. The 5 MC state is not involved in the deactivation pathway. The ultrafast partial deactivation of the 3 MLCT state constitutes a loss channel from the point of view of photochemical efficiency and highlights the necessity to screen transition-metal complexes for similar ultrafast decays to optimize photochemical performance.

RESUMO

We report x-ray free electron laser experiments addressing ground-state structural dynamics of the diplatinum anion Pt_{2}POP_{4} following photoexcitation. The structural dynamics are tracked with <100 fs time resolution by x-ray scattering, utilizing the anisotropic component to suppress contributions from the bulk solvent. The x-ray data exhibit a strong oscillatory component with period 0.28 ps and decay time 2.2 ps, and structural analysis of the difference signal directly shows this as arising from ground-state dynamics along the PtPt coordinate. These results are compared with multiscale Born-Oppenheimer molecular dynamics simulations and demonstrate how off-resonance excitation can be used to prepare a vibrationally cold excited-state population complemented by a structure-dependent depletion of the ground-state population which subsequently evolves in time, allowing direct tracking of ground-state structural dynamics.

RESUMO

BACKGROUND: The acute out-of-hours healthcare services are challenged by increasing demand in many countries. We aimed to examine factors influencing the intended help-seeking in out-of-hours care for acute health problems during evenings, nights, and weekends. METHODS: We conducted a survey study based on data from parents of children (aged 0-4 years) and adults (aged 30-39 and 50-59 years) in Denmark, the Netherlands and Switzerland. Intended help-seeking behaviour was measured by six hypothetical case scenarios. We used Andersen's Behavioural Model to categorise potentially influential factors and applied multiple binomial regression to assess the influence of selected factors. RESULTS: A total of 1015 parents and 2942 adults participated. We identified several significant influential factors. Parents holding a low education (OR 1.56), having migrant background (western: OR 1.23; non-western: OR 1.93), having one child (OR 1.24), perceiving few barriers to using out-of-hours primary care (OR 1.59), perceiving difficulties with organising childcare (OR 1.13), and having a history of frequent contacts with out-of-hours care (OR 1.55) were more inclined to contact out-of-hours care, whereas female (OR 0.85) and non-anxious parents (OR 0.77) were less inclined. Adults who were older (OR 1.01), holding a medical education (OR 1.13), having non-western background (OR 1.28), being unemployed (OR 1.17), perceiving few barriers to using out-of-hours primary care (OR 1.37), and having a history of frequent contacts with a GP (few: OR 1.15; more: OR 1.22) and/or with out-of-hours care (one: OR 1.20; more: OR 1.49) were more inclined to contact out-of-hours care, whereas adults with no or little social support (OR 0.84) and adults with high health literacy level on health information (OR 0.91) were less inclined. Dutch parents were less inclined than Danish parents to contact out-of-hours care (OR 0.62), whereas Swiss adults were more inclined than Danish adults to contact out-of-hours care (OR 1.16). CONCLUSION: We identified several factors related to intended help-seeking in out-of-hours care. These results could be used to develop targeted interventions, but more research is needed to examine the underlying explanations for the identified differences.

RESUMO

BACKGROUND: Out-of-hours (OOH) healthcare services in Western countries are often differentiated into out-of-hours primary healthcare services (OOH-PC) and emergency medical services (EMS). Call waiting time, triage model and intended aims differ between these services. Consequently, the care pathway and outcome could vary based on the choice of entrance to the healthcare system. We aimed to investigate patient pathways and 1- and 1-30-day mortality, intensive care unit (ICU) stay and length of hospital stay for patients with acute myocardial infarction (AMI), stroke and sepsis in relation to the OOH service that was contacted prior to the hospital contact. METHODS: Population-based observational cohort study during 2016 including adult patients from two Danish regions with an OOH service contact on the date of hospital contact. Patients <18 years were excluded. Data was retrieved from OOH service databases and national registries, linked by a unique personal identification number. Crude and adjusted logistic regression analyses were performed to assess mortality in relation to contacted OOH service with OOH-PC as the reference and cox regression analysis to assess risk of ICU stay. RESULTS: We included 6826 patients. AMI and stroke patients more often contacted EMS (52.1 and 54.1%), whereas sepsis patients predominately called OOH-PC (66.9%). Less than 10% (all diagnoses) of patients contacted both OOH-PC & EMS. Stroke patients with EMS or OOH-PC & EMS contacts had higher likelihood of 1- and 1-30-day mortality, in particular 1-day (EMS: OR = 5.33, 95% CI: 2.82-10.08; OOH-PC & EMS: OR = 3.09, 95% CI: 1.06-9.01). Sepsis patients with EMS or OOH-PC & EMS contacts also had higher likelihood of 1-day mortality (EMS: OR = 2.22, 95% CI: 1.40-3.51; OOH-PC & EMS: OR = 2.86, 95% CI: 1.56-5.23) and 1-30-day mortality. Risk of ICU stay was only significantly higher for stroke patients contacting EMS (EMS: HR = 2.38, 95% CI: 1.51-3.75). Stroke and sepsis patients with EMS contact had longer hospital stays. CONCLUSIONS: More patients contacted OOH-PC than EMS. Sepsis and stroke patients contacting EMS solely or OOH-PC & EMS had higher likelihood of 1- and 1-30-day mortality during the subsequent hospital contact. Our results suggest that patients contacting EMS are more severely ill, however OOH-PC is still often used for time-critical conditions.
