    • DN DEBATT 15/3. Sedan industrialiseringens början har vi använt omkring fyra femtedelar av den mängd fossilt kol som får förbrännas för att vi ska klara Parisavtalet. Vi har bara en femtedel kvar och det är bråttom att kraftigt reducera utsläppen. Det har Greta Thunberg och de strejkande ungdomarna förstått. Därför stödjer vi deras krav, skriver 270 klimatforskare.

  • Blood pressure after modified uvulopalatopharyngoplasty : results from the SKUP3 randomized controlled trial.
  • 2017
  • Ingår i: Sleep medicine. - 1878-5506. ; 34, s. 156-161
  • Tidskriftsartikel (refereegranskat)abstract
    • ObjectiveObstructive sleep apnea (OSA) is a risk factor for hypertension. The SKUP3 study showed that modified uvulopalatopharyngoplasty (UPPP) significantly improved nocturnal respiration, sleepiness, and quality of life. The aim of this study was to evaluate the impact of surgery on blood pressure in patients with OSA.MethodsWe used a single-center randomized controlled trial to compare modified UPPP with controls at baseline and after six months. The controls received delayed surgery with an additional six-month follow-up. All operated patients also had a follow-up after 24 months. Polysomnography was performed at each follow-up, with systolic and diastolic blood pressure (SBP, DBP) measured the morning after.ResultsA total of 65 patients were randomized to intervention (n = 32) or control (n = 33). At follow-up (n = 61/65, 94%), there were significant differences between the groups in both mean SBP (−9.4 mmHg [95% CI: −17.9, −0.83], p < 0.05) and mean DBP (−6.4 mmHg [95% CI: −12.8, −0.04], p < 0.05), in favor of UPPP. Blood pressure and respiratory parameters at follow-up correlated. The analyses of all operated patients showed a significant decrease in mean (SD) blood pressure after six months (n = 49/65, 75%; SBP: −4.5 [9.0], p = 0.001; DBP: −2.2 [6.6], p = 0.030) as well as after 24 months (n = 35/65, 54%; SBP: −8.9 [11.5], p < 0.0001; DBP: −4.2 [9.4], p = 0.012).ConclusionsBlood pressure was significantly decreased after surgery, indicating that modified UPPP decreases the blood pressure, in a selected group of patients with moderate to severe OSA. The long-term effect was also significant, but these results are uncertain due to a high proportion of missing values.

    • The Swedish Web-system for Enhancement and Development of Evidence-based care in Heart disease Evaluated According to Recommended Therapies (SWEDEHEART) supports continuous monitoring and improvement of care for coronary artery disease, catheter-based and surgical coronary interventions, secondary prevention as well as catheter based and surgical valve intervention, by providing extensive data on base-line, diagnostic, procedural and outcome variables. Design. This national quality registry collects information from all Swedish hospitals treating patients with acute coronary artery disease and all patients undergoing coronary angiography, catheter-based interventions or heart surgery. Combination with other national mandatory official registries enables complete follow-up of all individuals regarding myocardial infarction, new interventional procedures, death and all-cause hospitalizations. The registry is governed by an independent steering committee and funded by the Swedish National Health care provider. The software is developed by Uppsala Clinical Research Center. Results. The SWEDEHEART Quality Index reflects overall quality of care for coronary artery disease including secondary prevention. In comparison with 2011, an improvement of the index occurred in 2012 overall. There was however, still a wide range in performance between individual centers, emphasizing the need for continuous monitoring of quality of care at a national as well as on a center level. © 2014 Informa Healthcare.

    • Abstract Objectives. The Swedish Web-system for Enhancement and Development of Evidence-based care in Heart disease Evaluated According to Recommended Therapies (SWEDEHEART) collects data to support the improvement of care for heart disease. Design. SWEDEHEART collects on-line data from consecutive patients treated at any coronary care unit n = (74), followed for secondary prevention, undergoing any coronary angiography, percutaneous coronary intervention, percutaneous valve or cardiac surgery. The registry is governed by an independent steering committee, the software is developed by Uppsala Clinical Research Center and it is funded by The Swedish national health care provider independent of industry support. Approximately 80,000 patients per year enter the database which consists of more than 3 million patients. Results. Base-line, procedural, complications and discharge data consists of several hundred variables. The data quality is secured by monitoring. Outcomes are validated by linkage to other registries such as the National Cause of Death Register, the National Patient Registry, and the National Registry of Drug prescriptions. Thanks to the unique social security number provided to all citizens follow-up is complete. The 2011 outcomes with special emphasis on patients more than 80 years of age are presented. Conclusion. SWEDEHEART is a unique complete national registry for heart disease.

  • Variability in functional outcome and treatment practices by treatment center after out-of-hospital cardiac arrest : analysis of International Cardiac Arrest Registry
  • 2019
  • Ingår i: Intensive Care Medicine. - : Springer. - 0342-4642 .- 1432-1238. ; 45:5, s. 637-646

    • PurposeFunctional outcomes vary between centers after out-of-hospital cardiac arrest (OHCA) and are partially explained by pre-existing health status and arrest characteristics, while the effects of in-hospital treatments on functional outcome are less understood. We examined variation in functional outcomes by center after adjusting for patient- and arrest-specific characteristics and evaluated how in-hospital management differs between high- and low-performing centers.MethodsAnalysis of observational registry data within the International Cardiac Arrest Registry was used to perform a hierarchical model of center-specific risk standardized rates for good outcome, adjusted for demographics, pre-existing functional status, and arrest-related factors with treatment center as a random effect variable. We described the variability in treatments and diagnostic tests that may influence outcome at centers with adjusted rates significantly above and below registry average.ResultsA total of 3855 patients were admitted to an ICU following cardiac arrest with return of spontaneous circulation. The overall prevalence of good outcome was 11-63% among centers. After adjustment, center-specific risk standardized rates for good functional outcome ranged from 0.47 (0.37-0.58) to 0.20 (0.12-0.26). High-performing centers had faster time to goal temperature, were more likely to have goal temperature of 33 degrees C, more likely to perform unconscious cardiac catheterization and percutaneous coronary intervention, and had differing prognostication practices than low-performing centers.ConclusionsCenter-specific differences in outcomes after OHCA after adjusting for patient-specific factors exist. This variation could partially be explained by in-hospital management differences. Future research should address the contribution of these factors to the differences in outcomes after resuscitation.

    • OBJECTIVES: Our goal was to validate the Swedish Cardiac Surgery Registry by reviewing the reported cardiac operations to assess the completeness and quality of the registered data and the EuroSCORE II variables. METHODS: A total of 5837 cardiac operations were reported to the Swedish Cardiac Surgery Registry in Sweden during 2015. A randomly selected sample of 753 patient records (13%) was scrutinized by 3 surgeons at all 8 units in Sweden performing open cardiac surgery in adults. RESULTS: Coverage was excellent with 99% [95% confidence interval (CI) 98-99%] of the performed procedures found in the registry. Reported waiting times for surgery were correct in 78% (95% CI 76-79%) of the cases. The main procedural code was correctly reported in 96% (95% CI 95-97%) of the cases. The correlation between reported and monitored logistic EuroSCORE II had a coefficient of 0.79 (95% CI 0.76-0.82), and the median difference in EuroSCORE II was 0% (interquartile range -0.4% to 0.4%). The majority of EuroSCORE II variables had good agreement and coherence; however, New York Heart Association functional class, preoperative renal dysfunction, left ventricular ejection fraction, Canadian Cardiovascular Society Class IV angina and poor mobility were less robust Postoperative complications were rare and in general had a high degree of completeness and agreement. CONCLUSIONS: The reliability of the variables in the national Swedish Cardiac Surgery Registry was excellent. Thus, the registry is a valuable source of data for quality studies and research. Some EuroSCORE II variables require improved and stricter definitions to obtain uniform reporting and high validity.

  • Placing children and adolescents at the centre of the Sustainable Development Goals will deliver for current and future generations
  • 2019

    • Child health is taking the back seat in development strategies. In summarising a newly released collaborative report, this paper calls for a novel conceptual model where child health takes centre stage in relation to the 2030 Agenda and the Sustainable Development Goals. It lays out five principles by which renewed effort and focus would yield the most benefit for children and adolescents. These include: re-defining global child health in the post-2015 era by placing children and adolescents at the centre of the Sustainable Development Goals; striving for equity; realising the rights of the child to thrive throughout the life-course; facilitating evidence informed policy-making and implementation; and capitalising on interlinkages within the SDGs to galvanise multisectoral action. These five principles offer models that together have the potential of improving design, return and quality of global child health programs while re-energising the 2030 Agenda and the Sustainable Development Goals.

  • Cost-effectiveness of mass screening for untreated atrial fibrillation using intermittent ECG recording
  • 2015
  • Ingår i: Europace. - : Oxford University Press (OUP): Policy B - Oxford Open Option B - CC-BY. - 1099-5129 .- 1532-2092. ; 17:7, s. 1023-1029

    • Aims The aim of this study was to estimate the cost-effectiveness of 2 weeks of intermittent screening for asymptomatic atrial fibrillation (AF) in 75/76-year-old individuals. Methods and results The cost-effectiveness analysis of screening in 75-year-old individuals was based on a lifelong decision analytic Markov model. In this model, 1000 hypothetical individuals, who matched the population of the STROKESTOP study, were simulated. The population was analysed for different parameters such as prevalence, AF status, treatment with oral anticoagulation, stroke risk, utility, and costs. In the base-case scenario, screening of 1000 individuals resulted in 263 fewer patient-years with undetected AF. This implies eight fewer strokes, 11 more life-years, and 12 more quality-adjusted life years (QALYs) per 1000 screened individuals. The screening implies an incremental cost of (sic)50 012, resulting in a cost of (sic)4313 per gained QALY and (sic)6583 per avoided stroke. Conclusions With the use of a decision analytic simulation model, it has been shown that screening for asymptomatic AF in 75/76-year-old individuals is cost-effective.

    • Aims: The primary objective of this study was to use computer simulations to suggest an optimal age for initiation of screening for unknown atrial fibrillation and to evaluate if repeated screening will add value.Methods and results: In the absence of relevant clinical studies, this analysis was based on a simulation model. More than two billion different designs of screening programs for unknown atrial fibrillation were simulated and analysed. Data from the published scientific literature and registries were used to construct the model and estimate lifelong effects and costs. Costs and effects generated by 2 147 483 648 different screening designs were calculated and compared. Program designs that implied worse clinical outcome and were less cost-effective compared to other programs were excluded from the analysis. Seven program designs were identified, and considered to be cost effective depending on what the health-care decision makers are ready to pay for gaining a quality-adjusted life-year (QALY). Screening at the age of 75 implied the lowest cost per gained QALY (€4 800/QALY).Conclusion: In conclusion, examining the results of more than two billion simulated screening program designs for unknown atrial fibrillation, seven designs were deemed cost-effective depending on how much we are prepared to pay for gaining QALYs. Our results showed that repeated screening for atrial fibrillation implied additional health benefits to a reasonable cost compared to one-off screening.

  • Net benefit of oral anticoagulants in patients with atrial fibrillation and active cancer : a nationwide cohort study
  • 2020
  • Ingår i: Europace. - : Oxford University Press. - 1099-5129 .- 1532-2092. ; 22:1, s. 58-65

    • Aims: To estimate the net cerebrovascular benefit of prophylactic treatment with oral anticoagulants (OACs) in patients with atrial fibrillation (AF) and active cancer.Methods and results: We included all Swedish patients who had been diagnosed with AF in a hospital or in a hospital-associated outpatient unit between 1 July 2005 and 1 October 2017. Patients with active cancer (n = 22 596) and without cancer (n = 440 848) were propensity score matched for the likelihood of receiving OACs at baseline. At baseline, 38.3% of cancer patients with AF and high stroke risk according to CHA2DS2-VASc score received OACs. There was a net benefit of OACs, assessed by the composite outcome of ischaemic stroke, extracranial arterial thromboembolism, all major bleedings, and death, both among patients with active cancer [hazard ratio (HR): 0.81, confidence interval (CI): 0.78-0.85] and among patients without cancer (HR: 0.81, CI: 0.80-0.82). When limiting follow-up to 1 year to minimize the effects of possible treatment cross-over and additionally accounting for death as a competing risk in cancer patients, a net cerebrovascular benefit regarding ischaemic stroke or intracranial bleeding was observed for OACs [subhazard ratio (sHR): 0.67, CI: 0.55-0.83]. A net cerebrovascular benefit was also seen for non-vitamin K antagonist OACs over warfarin after competing risk analyses in cancer patients (sHR: 0.65, CI: 0.48-0.88).Conclusion: Patients with AF and active cancer benefit from OAC treatment.
