PurposeThis study investigated health-related quality of life (HRQOL) and psychological distress among young adult (YA) survivors of childhood cancer and the association of these measures with treatment, education, and demographic factors ≥ 5 years post diagnosis.MethodsParticipants included cancer survivors (n = 91) recruited through the Cancer Registry of Norway (CRN) and healthy controls (n = 223) recruited from a student population. All participants completed self-report questionnaires, and the Pediatric Quality of Life Inventory (PedsQL™) 4.0 and the Hopkins Symptom Checklist-10 (HSCL-10) as a measure of HRQOL and distress, respectively.ResultsSurvivors reported HRQOL at the same level as controls, except for poorer physical functioning. Survivors in general, and female survivors specifically, had higher odds than controls of reporting symptoms of distress above cut-off, but survivors did not have higher mean levels of distress compared to controls. Survivors reporting distress levels above the cut-off had significantly poorer HRQOL regarding physical functioning and lower total PedsQL scores than controls scoring above the cut-off. Age (for HRQOL only), female gender, low educational level, and perceived low economic status significantly predicted HRQOL and distress. Education interacted with the effect of cranial radiation in predicting HRQOL.ConclusionsSurvivors reported similar mean levels of HRQOL and distress as controls, except for physical functioning. For cancer survivors, demographic variables predicted HRQOL and distress. Some groups of survivors require closer follow-up, and more attention should be paid to factors associated with poor HRQOL and psychological distress in survivors, including female gender, lower education level, and lower income. Survivors treated with cranial radiation may be particular vulnerable in combination with low education regarding HRQOL.
BackgroundThe risks of intracranial haemorrhage (ICH) associated with antithrombotic drugs outside clinical trials are gaining increased attention. The aim of this nationwide study was to investigate the risk of ICH requiring hospital admission in users of antithrombotic drugs.Methods and findingsData from the Norwegian Patient Registry and Norwegian Prescription Database were linked on an individual level. The primary outcome was incidence rates of ICH associated with use of antithrombotic drugs. Secondary endpoints were risk of ICH and fatal outcome following ICH assessed by Cox models. Among 3,131,270 individuals ≥18 years old observed from 2008 through 2014, there were 729,818 users of antithrombotic medications and 22,111 ICH hospitalizations. Annual crude ICH rates per 100 person-years were 0.076 (95% CI, 0.075–0.077) in non-users and 0.30 (95% CI, 0.30–0.31) in users of antithrombotic medication, with the highest age and sex adjusted rates observed for aspirin-dipyridamole plus clopidogrel (0.44; 95% CI, 0.19–0.69), rivaroxaban plus aspirin (0.36; 95% CI, 0.16–0.56), warfarin plus aspirin (0.34; 95% CI, 0.26–0.43), and warfarin plus aspirin and clopidogrel (0.33; 95% CI, 0.073–0.60). With no antithrombotic medication as reference, the highest adjusted hazard ratios (HR) for ICH were observed for aspirin-dypiridamole plus clopidogrel (6.29; 95% CI 3.71–10.7), warfarin plus aspirin and clopidogrel (4.38; 95% CI 2.71–7.09), rivaroxaban plus aspirin (3.82; 95% CI, 2.46–5.95), and warfarin plus aspirin (3.40; 95% CI, 2.99–3.86). All antithrombotic medication regimens were associated with an increased risk of ICH, except dabigatran monotherapy (HR 1.20; 95% CI, 0.88–1.65) and dabigatran plus aspirin (HR 1.79; 95% CI, 0.96–3.34). Fatal outcome within 90 days was more common in users (2,603 of 8,055) than non-users (3,228 of 14,056) of antithrombotic medication (32.3% vs 23.0%, p<0.001), and was associated with use of warfarin plus aspirin and clopidogrel (HR 2.89; 95% CI, 1.49–5.60), warfarin plus aspirin (HR 1.37; 95% CI, 1.11–1.68), aspirin plus clopidogrel (HR 1.30; 95% CI, 1.05–1.61), and warfarin (HR 1.19; 95% CI, 1.09–1.31). Increased one-year mortality was observed in users of antithrombotic medication following hemorrhagic stroke, subdural hemorrhage, subarachnoid hemorrhage, and traumatic ICH (all p<0.001). Limitations include those inherent to observational studies including the inability to make causal inferences, certain assumptions regarding drug exposure, and the possibility of residual confounding.ConclusionsThe real-world incidence rates and risks of ICH were generally higher than reported in randomized controlled trials. There is still major room for improvement in terms of antithrombotic medication safety (clinicaltrials.gov NCT02481011).
ObjectivesAdministrative health registries need to have accurate diagnoses and sufficient coverage in the population they serve in order to be useful in research. In this study, we investigated the proportion of discharge diagnoses of intracranial hemorrhage (ICH) that were coded correctly in the Norwegian Patient Registry (NPR).Materials and MethodsWe reviewed the electronic medical records and diagnostic imaging of all admissions to St. Olavs University Hospital, Trondheim, Norway, between January 1, 2008, to December 31, 2014, with a discharge diagnosis of ICH in the NPR, and estimated positive predictive values (PPVs) for primary and secondary diagnoses. Separate calculations were made for inpatient and outpatient admissions.ResultsIn total, 1,419 patients with 1,458 discharge diagnoses of ICH were included in our study. Overall, 1,333 (91.4%) discharge diagnoses were coded correctly. For inpatient admissions, the PPVs for primary discharge codes were 96.9% for hemorrhagic stroke, 95.3% for subarachnoid hemorrhage, and 97.9% for subdural hemorrhage. The most common cause of incorrect diagnosis was previous stroke that should have been coded as rehabilitation or sequela after stroke. There were more false‐positive diagnoses among outpatient consultations and secondary diagnoses.ConclusionCoding of ICH discharge diagnoses in the NPR is of high quality, showing that data from this registry can safely be used for medical research.
BackgroundAccurate and reliable clinical and radiological predictors of intracerebral hemorrhage (ICH) outcomes are needed to optimize treatment of ICH. The aim of this study was to investigate functional outcome and identify predictors of severe disability or death following ICH.Materials and methodsRetrospective population‐based study of spontaneous ICH. Clinical and radiological data were obtained from electronic medical records, and functional outcome estimated using the modified Rankin Scale (mRS) before ICH and at 3 and 12 months after ICH.ResultsFour hundred and fifty‐two patients were included (mean age 74.8 years, 45.6% females). Proportion of fatal outcome at 1 week was 22.1%, at 3 months 39.2%, and at 12 months 44.9%. Median mRS score before the ICH was 1 (interquartile range [IQR] 2); for survivors at 3 months, it was 5 (IQR 3); and at 12 months, it was 3 (IQR 2). Independent predictors of severe disability (mRS of 5) or death (mRS of 6) were use of oral antithrombotic drugs (OR 2.2, 95% CI 1.3–3.8, p = 0.04), mRS score before the ICH (OR 1.8, 95% CI 1.4–2.2, p < 0.001), Glasgow Coma Scale (GCS) on admission (OR 8.3, 95% CI 3.5–19.7, p < 0.001), hematoma volume >60 ml (OR 4.5, 05% CI 2.0–10.2, p < 0.001), and intraventricular hematoma extension (OR 1.8, 95% CI 0.8–4.2, p < 0.001).ConclusionIntracerebral hemorrhage is associated with high mortality, and more than one third of survivors end up with severe disability or death 3 months later. Predictors of severe disability or death were use of oral antithrombotic drugs, functional disability prior to ICH, low GCS on admission, larger hematoma volume, and intraventricular hematoma extension.
Background To provide age-and sex-specific incidence and case fatality rates for non-traumatic aneurysmal subarachnoid hemorrhage (aSAH) in Norway. We also studied time trends in incidence and case fatality, as well as predictors of death following aSAH. Methods A nationwide study using discharge data for patients admitted with aSAH between 2008 and 2014. Results A total of 1732 patients with aSAH were included. The mean age was 60 years (SD 14) and 63% were females. Crude annual incidence was 5.7 per 100,000 person-years (95% CI 5.4-6.0) and was higher in females (6.3 per 100,000, 95% CI 5.9-6.7) compared with males (4.9 per 100,000, 95% CI 4.5-5.3). The annual decline in aSAH incidence was 3.2% per year (p = 0.007). The cumulative proportions of fatalities at days 30, 90, and 1 year were 22%, 25%, and 37%, respectively. The 30-day mortality rate did not change during the study period. Age (HR 0.7-2.2) and aneurysms in the posterior circulation (HR 1.7, 95% CI 1.3-2.3, p = 0.001) were associated with higher 30-day case fatality following aSAH, while aneurysm repair (HR 0.2, 95% CI 0.2-0.3, p < 0.001) was associated with lower risk. Conclusions The incidence of aSAH declined in Norway between 2008 and 2014. Case fatality following aSAH continues to be high, and the 30-day mortality during the study period was unchanged. Increasing age and aneurysms in the posterior circulation were associated with increased risk of death within 30 days following aSAH.
