There has been marked improvement in leukemia survival, particularly among children in recent time. However, the long-term trends in survival among adult leukemia patients and the associated sex and racial survival disparities are not well understood. We, therefore, evaluated the secular trends in survival improvement of leukemia patients from 1973 through 2014, using Surveillance Epidemiology and End-Result Survey Program (SEER) data. ICD-O-3 morphology codes were used to group leukemia into four types: acute lymphoblastic leukemia (ALL), acute myeloid leukemia (AML), chronic lymphocytic leukemia (CLL), chronic myeloid leukemia (CML). Survival analysis for each leukemia type stratified by race/ethnicity, age, sex was performed to generate relative survival probability estimates for the baseline time period of 1973 through 1979. Hazard ratios (HR) and respective 95% confidence intervals (CIs) for survival within subsequent 10-year time periods by race, age and sex were calculated using Cox proportional hazard models. Of the 83,255 leukemia patients for the current analysis, the 5-year survival of patients with ALL, AML, CLL, and CML during 1973-1979 were 42.0%, 6.5%, 66.5%, and 20.9%, respectively. Compared to the baseline, there were substantial improvements of leukemia-specific survival in 2010-2014 among African-American (81.0%) and Asian (80.0%) patients with CML and among 20-49 year of age with CLL (96.0%). African-American patients, those with AML and those older than 75 years of age had the lowest survival improvements. Asians experienced some of the largest survival improvements during the study period. Others, including African-American and the elderly, have not benefited as much from advances in leukemia treatment.

The objectives of this study were to analyze in-hospital adverse drug events (ADEs) in Portuguese public hospitals, and their association with mortality and the duration of hospitalization. We analyzed an administrative database containing the registration of all hospitalizations occurring in Portuguese public hospitals in 2013-2015. ADEs were identified using the codes E850-858.9 and E930-949.9 from ICD-9-CM. We identified all episodes with registration of in-hospital ADE and we compared them with a random sample of an equal number of episodes with no events recorded. A total of 3,041,443 cases were analyzed, 60,521 presented at least one ADE from which 17,213 occurred in hospital context. The most frequent drug classes associated with ADE were the antineoplastics/immunosuppressant drugs, antibiotics and steroids. Patient characteristics associated with a greater occurrence of in-hospital ADEs (all with p < 0.001) were medical admissions (OR = 1.29), the diagnosis - myeloid leukaemia (OR = 18.63), nephrotic syndrome (OR = 15.75), pneumonia (OR = 1.33) -, a higher number of secondary diagnoses (OR = 1.27), and increased duration of hospital stay (OR = 1.06). Hospitalizations with records of in-hospital ADEs presented a significantly higher mortality (9.6% vs. 4.5) and duration of hospitalization (22.6 vs. 6.4 days). ADEs were shown to be directly associated with an increase in the duration of hospital stay of 8.18 days. This study adds some interesting insights related to the most frequent drug classes and patient characteristics that can influence the frequency of ADEs in Portuguese public hospitals and also the burden of injury resulting from them.
