Leukemia, together with lymphoma and multiple myeloma, are hematological malignancies, malignancies of the blood-forming organs. There are four major types of leukemia: acute lymphocytic leukemia (ALL), acute myeloid leukemia (AML), chronic myeloid leukemia (CML), and chronic lymphocytic leukemia (CLL). There is a growing amount of lit...
The purpose of this study was to estimate the risk and mortality of breast cancer recurrences in Swedish women, and to analyse changes over time and variations between patients in different risk groups. Such estimates are of key importance for modelling the cost-effectiveness of different strategies for adjuvant treatment of breast cancer. The stud...
An increasing regulation for pricing and reimbursement decisions is associated with both costs and benefits. One potential cost is a delayed introduction of drugs on the market. The objective of this study was to discuss and analyse the time lag between drug authorisation and reimbursement for new chemical entities (NCEs) in Sweden and Finland.
The...
Women are usually not considered for abdominal aortic aneurysm (AAA) screening because of their lower prevalence of disease. This position may, however, be questioned given the higher risk of rupture and the longer life expectancy among women. The purpose of this study was to assess the cost-effectiveness of screening 65-year-old women for AAA.
A s...
Hypoglycemia is a common side effect of antidiabetic therapy. In addition to reducing well-being, hypoglycemic events may lead to substantial costs of medical care and lost productivity. The cost of hypoglycemia is, however, not well identified, particularly in patients with Type 2 diabetes. The purpose of this study was to assess the cost of hypog...

Abstract Adverse drug reactions (ADRs) are common causes of hospitalization and lead to large costs to society. The cost of hospitalization is, however, only a part of the total costs as most adverse reactions never come to clinical attention. There are two main costs associated with ADRs, cost of treating illnesses due to ADRs and cost of avoiding...
Influenza disease is a major cause of morbidity and mortality in the elderly and at-risk adults. Despite the international recommendations for vaccinating those at-risk populations, many countries still have not adopted this immunization program.
