Evaluating dynamic patterns in mortality before and after reconfiguration of the Danish emergency healthcare system.

BACKGROUND: This study explored changes in short-term mortality during a national reconfiguration of emergency care starting in 2007. METHODS: Unplanned hospital contacts at emergency departments across Denmark from 2007 to 2016. The reconfiguration was a natural experiment, resulting in individual timelines for each hospital. The outcome was in-hospital and 30-day mortality. RESULTS: Individual patient-level data included 9,745,603 unplanned hospital contacts from 2007 to 2016 at 20 hospitals with emergency departments. We observed a sharp downwards shift in in-hospital mortality and 30-day mortality in three hospitals in relation to the reconfiguration. CONCLUSION: This nationwide study identified three hospitals where the reconfiguration was closely associated with reduced in-hospital and 30-day mortality. In contrast, no major effects were identified for the remaining hospitals.

High Incidence of Cardiovascular Disease in Patients With Oesophageal Cancer-A Registry-Based Cohort Study.

BACKGROUND: The cardiovascular disease (CVD) burden among patients with oesophageal cancer (EC) treated with curative intent is unclear. AIM: To determine CVD incidence and all-cause mortality in patients with EC. METHOD: Danish national health registries were used to identify patients diagnosed with primary EC between 2008 and 2018. Each EC patient was matched with 10 individuals from the general population. The primary endpoint was a CVD hospital contact (CVD-HC), either admission or outpatient contact. Cox proportional hazard regression models were used to compare the risk of incident CVD-HCs between the cohorts. RESULTS: The study included 1,525 patients with EC and 15,250 individuals from the general population. Patients with EC had a post-diagnosis one-year adjusted hazard ratio (HR) of CVD-HC of 6.1 (95% confidence intervals [CIs] 5.6-6.8) compared with the general population. During the next nine years, the risk of CVD-HC was comparable between the two cohorts, with an adjusted HR of 1.0 (95% CI 0.9-1.3). Patients with EC, and particularly those with prevalent CVD, had a high risk of atrial fibrillation, ischaemic heart disease, and venous thromboembolism within the first year after EC diagnosis. Prevalent CVD among patients with EC was not associated with higher mortality. CONCLUSIONS: CVD morbidity was transiently increased in the first year following EC diagnosis compared with the general population. All-cause mortality risks were high but did not appear to be affected by prevalent CVD. The very high risk of CVD in patients with primary EC to be treated with curative intent calls for healthcare initiatives to advance preventive and post-treatment strategies.

Outcomes Following Adherence to a Randomized Stroke Trial Protocol.

This secondary analysis of a randomized clinical trial assesses whether compliance with the study protocol is associated with a better functional outcome even among participants in the sham-control group.

Transport Strategy in Patients With Suspected Acute Large Vessel Occlusion Stroke: TRIAGE-STROKE, a Randomized Clinical Trial.

BACKGROUND: When patients with acute ischemic stroke present with suspected large vessel occlusion in the catchment area of a primary stroke center (PSC), the benefit of direct transport to a comprehensive stroke center (CSC) has been suggested. Equipoise remains between transport strategies and the best transport strategy is not well established. METHODS: We conducted a national investigator-driven, multicenter, randomized, assessor-blinded clinical trial. Patients eligible for intravenous thrombolysis (IVT) who were suspected for large vessel occlusion were randomized 1:1 to admission to the nearest PSC (prioritizing IVT) or direct CSC admission (prioritizing endovascular therapy). The primary outcome was functional improvement at day 90 for all patients with acute ischemic stroke, measured as shift towards a lower score on the modified Rankin Scale score. RESULTS: From September 2018 to May 2022, we enrolled 171 patients of whom 104 had acute ischemic stroke. The trial was halted before full recruitment. Baseline characteristics were well balanced. Primary analysis of shift in modified Rankin Scale (ordinal logistic regression) revealed an odds ratio for functional improvement at day 90 of 1.42 (95% CI, 0.72-2.82, P=0.31). Onset to groin time for patients with large vessel occlusion was 35 minutes (P=0.007) shorter when patients were transported to a CSC first, whereas onset to needle (IVT) was 30 minutes (P=0.012) shorter when patients were transported to PSC first. IVT was administered in 67% of patients in the PSC group versus 78% in the CSC group and EVT was performed in 53% versus 63% of the patients, respectively. CONCLUSIONS: This trial investigated the benefit of bypassing PSC. We included only IVT-eligible patients presenting <4 hours from onset and with suspected large vessel occlusion. Lack of power prevented the results from showing effect on functional outcome for patients going directly to CSC. REGISTRATION: URL: https://www. CLINICALTRIALS: gov; Unique identifier: NCT03542188.

Inter-Rater Agreement on Cincinnati Prehospital Stroke Scale (CPSS) and Prehospital Acute Stroke Severity Scale (PASS) Between EMS Providers, Neurology Residents and Neurology Consultants.

Objective: To examine the agreement between emergency medical service (EMS) providers, neurology residents and neurology consultants, using the Cincinnati Prehospital Stroke Scale (CPSS) and the Prehospital Acute Stroke Severity Scale (PASS). Methods: Patients with stroke, transient ischemic attack (TIA) and stroke mimic were included upon primary stroke admission or during rehabilitation. Patients were included from June 2018 to September 2019. Video recordings were made of patients being assessed with CPSS and PASS. The recordings were later presented to the healthcare professionals. To determine relative and absolute interrater reliability in terms of inter-rater agreement (IRA), we used generalisability theory. Group-level agreement was determined against a gold standard and presented as an area under the curve (AUC). The gold standard was a consensus agreement between two neurology consultants. Results: A total of 120 patient recordings were assessed by 30 EMS providers, two neurology residents and two neurology consultants. Using the CPSS and the PASS, a total of 1,800 assessments were completed by EMS providers, 240 by neurology residents and 240 by neurology consultants. The overall relative and absolute IRA for all items combined from the CPSS and PASS score was 0.84 (95% CI 0.80; 0.87) and 0.81 (95% CI 0.77; 0.85), respectively. Using the CPSS, the agreement on a group-level resulted in AUCs of 0.83 (95% CI 0.78; 0.88) for the EMS providers and 0.86 (95% CI 0.82; 0.90) for the neurology residents when compared with the gold standard. Using the PASS, the AUC was 0.82 (95% CI 0.77; 0.87) for the EMS providers and 0.88 (95% CI 0.84; 0.93) for the neurology residents. Conclusion: The high relative and absolute inter-rater agreement underpins a high robustness/generalisability of the two scales. A high agreement exists across individual raters and different groups of healthcare professionals supporting widespread applicability of the stroke scales.

Time trends in income-related disparity in incidence of acute coronary syndrome.

BACKGROUND: Higher incidence of acute coronary syndrome (ACS), among those with lower income, has been recognized in the most recent decades. Still, there is a paucity of data on temporal changes. This study aims to investigate 20-year time trends in income-related disparity in the incidence of ACS in Denmark. METHODS: This Population-based repeated cross-sectional study included all patients with first-time ACS, aged ≥20 years, registered in the Danish National Patient Registry 1998-2017. Aggregated sociodemographic data for the Danish population was accessed from Statistics Denmark. Yearly incidence rates (IR) and incidence rate ratios (IRR), with the highest-income quartile as a reference, were standardized using cell-specific personal equivalent income according to year, sex and age group with 95% confidence intervals. Interaction analysis was executed for differences in IR of ACS between the lowest- and highest-income quartile over time. RESULTS: A total of 220 070 patients hospitalized with ACS from 1998 to 2017 were identified. The yearly standardized ACS IRs decreased in all income quartiles. However, the IR remained higher in the lowest-income quartile compared to the highest for both men [1998: IRR 1.45 (95% confidence interval, CI 1.39-1.52) and 2017: 1.47 (1.40-1.54)] and women [1998: IRR 1.73 (1.64-1.82) and 2017: 1.76 (1.65-1.88)]. Interaction analysis showed that over the period the difference in IR between the lower- and the highest-income quartile decreased with 1-5 ACS cases per 100 000 person-year. CONCLUSION: Income-related disparity in the incidence of ACS was present in Denmark between 1998 and 2017. Despite a marked overall decrease in the yearly ACS incidence, the extent of income-related disparity remained unchanged.

Long-Term Temporal Trends in Survival Among Danish Patients with Advanced Cutaneous Melanoma: A Nationwide Follow-Up Study.

Introduction: Population-based data on survival trends over time among patients with advanced cutaneous melanoma are lacking. We examined changes in mortality for patients diagnosed from 1980 to 2011 in a nationwide historical follow-up study using population-based medical registries from Denmark. Material and Methods: The study population included all Danish patients with an incident diagnosis of advanced (metastatic or unresectable stage IIIA, IIIB, IIIC, or IV) cutaneous melanoma (ie, initial diagnosis for melanoma at stage III/IV) between 1980-2011 and who were followed-up until 2013. For each patient, we randomly matched 100 individuals from the general population on sex and year of birth. Age-standardized mortality rates were calculated by calendar year of diagnosis overall, 30 days after diagnosis, and during 31 to 364 days and 0-10 years after diagnosis. Stratified Cox's proportional hazards regression was used to compute hazard ratios. Results: We identified a total of 1236 patients and 123,600 comparison cohort members. We observed that the standardized mortality rates of patients with advanced melanoma dropped from the 1980s onwards, but remain high (eg, 74.3 and 248.4 per 1000 person-years in 0-30 days and 31-364 days after diagnosis, respectively, for patients diagnosed during 2008-2011). Compared with the general population, patients with advanced melanoma had a 10.4-fold increased hazard of death during 0-10 years of follow-up. The highest relative mortality was found for the first year following melanoma diagnosis. No improvements in survival compared to the general population were observed in the most recent years of the study period, thus in 2004-2007 and 2008-2011. Discussion and Conclusion: Survival of patients with advanced cutaneous melanoma in Denmark improved between 1980 and 2013 but appears to have leveled off in the years leading up to more widespread introduction of newer immuno-oncology therapies.

Associations between emergency call stroke triage and pre-hospital delay, primary hospital admission, and acute reperfusion treatment among early comers with acute ischemic stroke.

To investigate the association between the Emergency Medical Service dispatcher's initial stroke triage and prehospital stroke management, primary admission to hospitals offering revascularization treatment, prehospital time delay, and rate of acute revascularization. In an observational cohort study, patients with acute ischemic stroke (AIS) in Denmark (2017-2018) were included if the emergency call to the Emergency Medical Dispatch Center (EMDC) was made within three hours after symptom onset. Among 3546 included AIS patients, the EMS dispatcher identified 74.6% (95% confidence interval (CI) 73.1-76.0) correctly as stroke. EMS dispatcher stroke recognition was associated with a higher rate of primary admission to a hospital offering revascularization treatment (85.8 versus 74.5%); producing an adjusted risk difference (RD) of 11.1% (95% CI 7.8; 14.3) and a higher rate of revascularization treatment (49.6 versus 41.6%) with an adjusted RD of 8.4% (95% CI 4.6; 12.2). We adjusted for sex, age, previous stroke or transient ischemic attack, and stroke severity. EMDC stroke recognition was associated with shorter prehospital delay. For all AIS patients, the adjusted difference was - 33.2 min (95% CI - 44.4; - 22.0). Among patients receiving acute revascularization treatment (n = 1687), the adjusted difference was -12.6 min (95% CI - 18.9; - 6.3). Stroke recognition by the EMS dispatcher was associated with a higher probability of primary admission to a hospital offering acute stroke treatment, and subsequently with a higher rate of acute revascularization treatment, and with an overall reduction in prehospital delay.

Temporal trends in socioeconomic disparity in clinical outcomes for patients with acute coronary syndrome.

AIMS: Socioeconomic factors are well-established determinants of clinical outcomes among patients with acute coronary syndrome (ACS) although quality of care has improved the last decades. This study aims to investigate 20-years temporal trends of socioeconomic disparity in 1-year incidence of major adverse cardiac events (MACE) among ACS patients in Denmark. METHODS: This population-based cohort study included all incident ACS patients in the Danish National Patient Registry during 1998-2017. Socioeconomic disparity was assessed by income and educational level. Patients were followed 1-year for MACE; defined as all-cause mortality, recurrent ACS, revascularization, stroke, or cardiac arrest. Adjusted MACE incidence rates (aIR) and hazard rate ratios (aHR) were computed with 95 % confidence intervals (CI) for five-year-periods. Changes in trends were examined from interaction analyses between the HR for five-year-periods and income and education, respectively. RESULTS: The study included 220,887 patients with first-time ACS. The incidence of MACE decreased within all income and education levels. In 1998-2002 the MACE aIR among patients with low income was 885[95%CI:863-907] versus 733[711-756]/1000-person-year among those with high income (aHR: 1.19[95%CI:1.15-1.23]). The aIRs decreased to 506[489-522] and 405[388-423]/1000-person-year, respectively, in 2013-2017 (aHR: 1.23[1.17-1.29]). The aIRs of MACE decreased correspondingly within all educational levels from 1998 to 2002 to 2013-2017. However, the socioeconomic disparity according to the interaction analyses persisted both according to income and educational level. CONCLUSION: Although 1-year clinical outcomes following ACS has improved substantially over the last decades, socioeconomic disparity persisted both according to income and education level.

Implementation of universal umbilical cord pH analysis in Denmark. A national register-based study.

INTRODUCTION: Umbilical cord blood gas analysis provides information about intrapartum hypoxia and is considered an important measure of quality in maternity care. Universal measurement of umbilical cord pH (UC-pH), as part of umbilical cord blood gas analysis, has been recommended in Denmark since 2009. The recommendation is that UC-pH is measured from the umbilical cord artery (pHUA ) and vein (pHUV ). The aim of this study was to evaluate the national implementation of universal measurement of UC-pH. MATERIAL AND METHODS: The study consisted of two parts. First, an evaluation of the implementation, that is, the proportion of births with measured UC-pH since the recommendation was introduced. Second, an evaluation of the cases in which UC-pH was missing. This analysis only involved births with gestational age ≥35 + 0 weeks. RESULTS: In the period 2009 to 2018 there were 560 889 singleton, live births with registered gestational age in Denmark. The proportion of births with measured pHUA and pHUV increased from 12.4% in 2009 to 82.8% in 2015 and then declined to 76.9% in 2018 (p < 0.001). When comparing the group with missing pH from one or both vessels to the group with both pHUA and pHUV we found lower occurrence of pregnancy and births complications in the first group, body mass index ≥35 (unadjusted RR: 0.89, 95% CI: 0.85-0.93), pregnancy induced medical conditions (RR: 0.86, 95% CI: 0.84-0.89), fetal distress during birth (RR: 0.77, 95% CI: 0.76-0.79), emergency cesarean section (RR: 0.80, 95% CI: 0.78-0.83) and serious births events (RR: 0.80, 95% CI: 0.74-0.86). In contrast, the occurrence of placental insufficiency (RR: 1.07, 95% CI: 1.03-1.11), small for gestational age (RR: 1.36, 95% CI: 1.30-1.43, for <2.3th percentile), hypothermia treatment (RR: 1.60, 95% CI: 1.21-2.14) and neonatal death (RR: 1.96, 95% CI: 1.40-2.74) were higher in the group without measured pHUA and pHUV . CONCLUSIONS: The use of UC-pH measurement has increased markedly in Denmark since universal measurement was recommended in 2009. Missing UC-pH from one or both vessels was associated with less complicated pregnancies and with small for gestational age, hypothermia treatment and neonatal death.

Quality in stroke care during the early phases of the COVID-19 pandemic: A nationwide study.

Introduction: Evidence-based early stroke care as reflected by fulfillment of process performance measures, is strongly related to better patient outcomes after stroke and transient ischemic attack (TIA). Detailed data on the resilience of stroke care services during the COVID-19 pandemic are limited. We aimed to examine the quality of early stroke care at Danish hospitals during the early phases of the COVID-19 pandemic. Materials and methods: We extracted data from Danish national health registries in five time periods (11 March, 2020-27 January, 2021) and compared these to a baseline pre-pandemic period (13 March, 2019-10 March, 2020). Quality of early stroke care was assessed as fulfilment of individual process performance measures and as a composite measure (opportunity-based score). Results: A total of 23,054 patients were admitted with stroke and 8153 with a TIA diagnosis in the entire period. On a national level, the opportunity-based score (95% confidence interval [CI]) at baseline for ischemic patients was 81.1% (80.8-81.4), for intracerebral hemorrhage (ICH) 85.5% (84.3-86.6), and for TIA 96.0% (95.3-96.1). An increase of 1.1% (0.1-2.2) and 1.5% (0.3-2.7) in the opportunity-based score was observed during the first national lockdown period for AIS and TIA followed by a decline of -1.3% (-2.2 to -0.4) in the gradual reopening phase for AIS indicators. We found a significant negative association between regional incidence rates and quality-of-care in ischemic stroke patients implying that quality decreases when admission rates increase. Conclusion: The quality of acute stroke/TIA care in Denmark remained high during the early phases of the pandemic and only minor fluctuations occurred.

Small-Area Analysis of Treatment and Clinical Outcomes in Patients with Venous Thromboembolism in Denmark: A Nationwide Cohort Study.

OBJECTIVES: To investigate geographical variation in initiation and extended treatment with anticoagulants and clinical outcomes among patients hospitalized with first-time venous thromboembolism (VTE) in Denmark between 2007 and 2018. METHODS: Using nationwide health care registries, we identified all patients with a first-time VTE hospital diagnosis supported by imaging data from 2007 to 2018. Patients were grouped according to residential region (5) and municipality (98) at the time of VTE diagnosis. Cumulative incidence of initiation of and extended (beyond 365 days) anticoagulation treatment as well as clinical outcomes, including recurrent VTE, major bleeding, and all-cause death, were assessed. Sex- and age-adjusted relative risks (RRs) of the outcomes were computed when comparing across individual regions and municipalities. Overall geographic variation was quantified by computing the median RR. RESULTS: We identified 66,840 patients with a first-time VTE hospitalization. A difference in initiation of anticoagulation treatment of more than 20 percentage points between regions was observed (range: 51.9-72.4%, median RR: 1.09, 95% confidence interval [CI]: 1.04-1.13). Variation was also observed for extended treatment (range: 34.2-46.9%, median RR: 1.08, 95% CI: 1.02-1.14). The cumulative incidence of recurrent VTE ranged from 3.6 to 5.3% at 1 year (median RR: 1.08, 95% CI: 1.01-1.15). The difference remained after 5 years, and variation was also observed for major bleeding (median RR: 1.09, 95% CI: 1.03-1.15), whereas it appeared smaller for all-cause mortality (median RR: 1.03, 95% CI: 1.01-1.05). CONCLUSION: Substantial geographical variation in anticoagulation treatment and clinical outcomes occurs in Denmark. These findings indicate a need for initiatives to ensure uniform high-quality care for all VTE patients.

Processes of Care and Associated Factors in Patients With Stroke by Immigration Status.

BACKGROUND: Receiving evidence-based stroke care processes is associated with good clinical outcome. However, data on early stroke care among immigrants are scarce. OBJECTIVE: We investigated whether guideline-recommended acute stroke care and associated factors differ between immigrants and Danish-born residents. DESIGN: Patients admitted with ischemic and hemorrhagic stroke diagnoses (n=129,724) between 2005 and 2018 were identified from the Danish Stroke Registry. RESULTS: We included 123,928 Danish-born residents and 5796 immigrants with stroke. Compared with Danish-born residents, immigrants were less likely to be admitted to a stroke unit within 24 hours after stroke onset (81.5% vs. 83.9%, P <0.001) and had lower odds of early stroke care including dysphagia screening, physiotherapy, occupational therapy, and nutritional assessment. After adjustment for age, sex, clinical, and sociodemographic factors, immigrants had lower odds of early stroke unit admission (odds ratio [OR]: 0.97; 95% CI, 0.94-0.99), early dysphagia screening (OR: 0.96; 95% CI, 0.93-0.98), early physiotherapy (OR: 0.96; 95% CI, 0.94-0.99), and early occupational therapy (OR: 0.96; 95% CI, 0.93-0.98) than Danish-born residents. Small absolute differences in overall quality of stroke care were found when comparing immigrants and Danish-born residents. Significant factors associated with greater likelihood of stroke care included high income, high education, and cohabitation. CONCLUSIONS: Immigrants had lower chances of early stroke unit admission and received fewer individual early stroke care processes such as dysphagia screening, physiotherapy and occupational therapy than Danish-born residents. However, the absolute disparities were in general minor and largely influenced by socioeconomic status and cohabitation.

An AI-based patient-specific clinical decision support system for OA patients choosing surgery or not: study protocol for a single-centre, parallel-group, non-inferiority randomised controlled trial.

BACKGROUND: Osteoarthritis (OA) affects 20% of the adult Danish population, and the financial burden to society amounts to DKK 4.6 billion annually. Research suggests that up to 75% of surgical patients could have postponed an operation and managed with physical training. ERVIN.2 is an artificial intelligence (AI)-based clinical support system that addresses this problem by enhancing patient involvement in decisions concerning surgical knee and hip replacement. However, the clinical outcomes and cost-effectiveness of using such a system are scantily documented. OBJECTIVE: The primary objective is to investigate whether the usual care is non-inferior to ERVIN.2 supported care. The second objective is to determine if ERVIN.2 enhances clinical decision support and whether ERVIN.2 supported care is cost-effective. METHODS: This study used a single-centre, non-inferiority, randomised controlled in a two-arm parallel-group design. The study will be reported in compliance with CONSORT guidelines. The control group receives the usual care. As an add-on, the intervention group have access to baseline scores and predicted Oxford hip/knee scores and HRQoL for both the surgical and the non-surgical trajectory. A cost-utility analysis will be conducted alongside the trial using a hospital perspective, a 1-year time horizon and effects estimated using EQ-5D-3L. Results will be presented as cost per QALY gain. DISCUSSION: This study will bring knowledge about whether ERVIN.2 enhances clinical decision support, clinical effects, and cost-effectiveness of the AI system. The study design will not allow for the blinding of surgeons. TRIAL REGISTRATION: ClinicalTrials.gov NCT04332055 . Registered on 2 April 2020.

Social determinants of health and recurrence of atrial fibrillation after catheter ablation: a Danish nationwide cohort study.

AIMS: To examine the associations between three social determinants of health (SDOH) and recurrence of AF after ablation. METHODS AND RESULTS: We selected patients who underwent a first ablation after an incident hospital diagnosis of AF between 2005 and 2018 from the entire Danish population. Educational attainment, family income, and whether the patient was living alone were assessed at the time of ablation. We used cause-specific proportional hazard models to estimate hazard ratios (HR) with 95% confidence interval (CI) adjusted for age and sex. In secondary analyses, we adjusted for comorbidities, antiarrhythmic medication, and prior electrical cardioversion.We selected 9728 patients (mean age 61 years, 70% men), and 5881 patients had AF recurrence over an average of 1.37 years after ablation (recurrence rate 325.7 (95% CI 317.6-334.2) per 1000 person-years). Lower education (HR 1.09 [1.02-1.17] and 1.07 [1.01-1.14] for lower and medium vs. higher), lower income [HR 1.14 (1.06-1.22) and 1.09 (1.03-1.17) for lower and medium vs. higher], and living alone [HR 1.07 (1.00-1.13)] were associated with increased rates of recurrence of AF. We found no evidence of interaction between sex or prior HF with SDOH. The association between family income and AF recurrence was stronger among patients < 65 years compared with those aged ≥ 65 years. The associations between SDOH and AF recurrence did not persist in the multivariable model. CONCLUSION: AF was more likely to recur among patients with lower educational attainment, lower family income, or those living alone. Multidisciplinary efforts are needed to reduce socioeconomic inequity in the effect of ablation.

Need for home care or nursing home admission after myocardial infarction complicated by cardiogenic shock and/or out-of-hospital cardiac arrest.

AIMS: Myocardial infarction (MI) with cardiogenic shock (CS) and/or out-of-hospital cardiac arrest (OHCA) are conditions with potential loss of autonomy. In patients with MI, the association between CS and OHCA and need for home care or nursing home admission was examined. METHODS AND RESULTS: Danish nationwide registries identified patients with MI (2008-19), who prior to the event lived at home without home care and discharged alive. One-year cumulative incidences and hazard ratios (HRs) were reported for home care need or nursing home admission, a composite proxy for disability in activities of daily living (ADL), along with all-cause mortality. The study population consisted of 67 109 patients with MI (by groups: -OHCA/-CS: 63 644; -OHCA/+CS: 1776; +OHCA/-CS: 968; and +OHCA/+CS: 721). The 1-year cumulative incidences of home care/nursing home were 7.1% for patients who survived to discharge with -OHCA/-CS, 20.9% for -OHCA/+CS, 5.4% for +OHCA/-CS, and 8.2% for those with +OHCA/+CS. The composite outcome was driven by home care. With the -OHCA/-CS as reference, the adjusted HRs for home care/nursing home were 2.86 (95% CI: 2.57-3.19) for patients with -OHCA/+CS; 1.31 (95% CI: 1.00-1.73) for + OHCA/-CS; and 2.18 (95% CI: 1.68-2.82) for those with +OHCA/+CS. The 1-year cumulative mortality were 5.1% for patients with -OHCA/-CS, 9.8% for -OHCA/+CS, 3.0% for +OHCA/-CS, and 3.4% for those with +OHCA/+CS. CONCLUSION: In patients discharged alive after a MI, CS, and to a lesser degree OHCA were associated with impaired ADL with a two-fold higher 1-year incidence of home care or nursing home admission compared with MI patients without CS or OHCA.

Impact of Stroke History on the Risk of Recurrent Hip Fracture or Major Osteoporotic Fractures among Patients with Incident Hip Fracture: A Nationwide Cohort Study.

Considerable uncertainty prevails regarding risk factors for recurrent fracture among older patients with hip fracture. We aimed to investigate the relationship between prefracture stroke history, baseline mobility, and the risk of recurrent hip fracture. This cohort study was based on the Danish Multidisciplinary Hip Fracture Registry, 2011-2018 (n = 48,230). We estimated cumulative incidence (competing risk of death) of recurrent hip fracture and major osteoporotic fractures within 1 and 2 years comparing patients with/without prefracture stroke history. Analyses were performed overall and stratified on baseline mobility status (good mobility: Cumulated Ambulation Score ≥ 5 versus poor mobility: Cumulated Ambulation Score < 5). Using Cox regression, adjusted cause-specific hazard ratios (HRs) with 95% confidence intervals (CIs) were obtained. The 1-year cumulative incidence was 4.6% (95% CI: 3.9-5.4) among patients with stroke history and 4.3% (95% CI: 4.1-4.5) among patients without stroke history. For patients with good mobility, the cumulative incidence of recurrent hip fracture was 5.8% (95% CI: 4.3-7.5) versus 3.7% (95% CI: 3.4-4.0) for patients with versus without stroke history. Corresponding numbers for patients with poor mobility were 4.4% (95% CI: 3.6-5.5) and 5.0% (95% CI: 4.7-5.3). Stroke history was associated with an adjusted HR of 1.55 (95% CI: 1.15-2.10) for recurrent fracture among patients with good mobility. In contrast, no association was observed among patients with poor mobility (adjusted HR 0.88 [95% CI: 0.70-1.10]). The associations were attenuated after 2 years of follow-up and for major osteoporotic fractures. In conclusion, stroke history was associated with slightly higher risk of recurrent fracture among patients with first-time hip fracture in the overall analysis, although the CI included a null result. The association was modified by baseline mobility: Patients with stroke history and good mobility had a markedly higher risk, whereas patients with stroke and poor mobility did not. © 2022 The Authors.

Trends and drivers of pharmaceutical expenditures from systemic anti-cancer therapy.

Expenditures on medicine for systemic anti-cancer therapy (SACT) have seen large increases in recent years. The characterization of patients with high SACT costs is crucial to identify cost-driving factors, but little is known about the distribution of expenditures at the patient-level. We priced 260,834 registrations of SACT for 12,589 patients from 2008 to 2019 by combining them with product-level billings of EUR 142.1 million. Based on this, we defined high-cost patients as the 2.5% most expensive by accumulated SACT expenditures. We found that high-cost patients accounted for 28.8% of the total SACT expenditures and were observed across all major cancer groups except for pancreatic cancer. The risk of becoming a high-cost patient was increased for younger age groups, i.e., 18-44 and 45-64 years, for patients with BMI ≥ 25, and for patients with multiple cancer diagnoses, while no alteration of risk was observed due to comorbidities or sex. Changes in the characteristics of high-cost patients during the study period were found with an increased risk of becoming high-cost in later years for elderly patients and patients with lung cancer and a decreased risk for breast cancer patients.
