Relationship between reasons for intermittent missing patient-reported outcomes data and missing data mechanisms.

Purpose: Non-response (NR) to patient-reported outcome (PRO) questionnaires may cause bias if not handled appropriately. Collecting reasons for NR is recommended, but how reasons for NR are related to missing data mechanisms remains unexplored. We aimed to explore this relationship for intermittent NRs.

Strategies to improve patient-reported outcome completion rates in longitudinal studies.

Purpose: The quality of patient-reported outcome (PRO) data can be compromised by non-response (NR) to scheduled questionnaires, particularly if reasons for NR are related to health problems, which may lead to unintended bias. The aim was to investigate whether electronic reminders and real-time monitoring improve PRO completion rate.

Methods: The population-based study "Quality of life in Danish multiple myeloma patients" is a longitudinal, multicentre study with consecutive inclusion of treatment-demanding newly diagnosed or relapsed patients with multiple myeloma.

A clinically based prognostic index for diffuse large B-cell lymphoma with a cut-off at 70 years of age significantly improves prognostic stratification: population-based analysis from the Danish Lymphoma Registry.

The introduction of rituximab and generally improved health among elderly patients have increased the survival of patients with diffuse large B-cell lymphoma (DLBCL). The International Prognostic Index (IPI) from 1992 is based on pre-rituximab data from clinical trials including several lymphoma subtypes. We applied IPI factors to a population-based rituximab-treated cohort of 1990 patients diagnosed 2000-2010 and explored new factors and the optimal prognostic age cut-off for DLBCL.

Evaluation of clinical trial eligibility and prognostic indices in a population-based cohort of systemic peripheral T-cell lymphomas from the Danish Lymphoma Registry.

Clinical trials (CTs) are needed to improve the outcome for peripheral T-cell lymphomas (PTCL), and accrual into CTs is one of the main recommendations in international treatment guidelines. The use of risk-adapted strategies has been suggested as a way to optimize treatment outcome in PTCL. The aim of the present study was to evaluate CT eligibility and selected prognostic indices in a population-based PTCL cohort of 481 PTCL patients identified from the Danish Lymphoma Registry in the period 2000-2010.

Role of routine imaging in detecting recurrent lymphoma: A review of 258 patients with relapsed aggressive non-Hodgkin and Hodgkin lymphoma.

After first-line therapy, patients with Hodgkin lymphoma (HL) and aggressive non-HL are followed up closely for early signs of relapse. The current follow-up practice with frequent use of surveillance imaging is highly controversial and warrants a critical evaluation. Therefore, a retrospective multicenter study of relapsed HL and aggressive non-HL (nodal T-cell and diffuse large B-cell lymphomas) was conducted.

[Structured documentation of patients' medical records. A new record structure for emergency admissions is coming].

Introduction: In recent years a range of efforts to shorten the length of stay (LOS) for patients admitted to hospitals has been tested. Some studies indicate that this might be accomplished by rigorous planning of patient pathways and structured documentation of medical records. In this study the effect of a structured case record model was tested.

[Prescribing and dispensing drugs in Denmark. Frequency of and intervention against errors in documentation and dispensing of drugs].

Foreign studies mainly describe errors in medicine prescriptions in context with adverse drug events unlike most Danish studies and projects, which focus on documentation. Current methods of prescribing medicines in Denmark only partially follow the guidelines given by the National Board of Health. About two thirds of the prescriptions are unambiguous.

[The Good Medical Department. Results from a national survey of quality in 1998].

Introduction: This cross-sectional study describes quality related data from 39 medical wards in Denmark.

Material And Methods: The study is based on a review of 1517 medical records and a short patient interview. The medical departments took part voluntarily in the study, which was initiated by the Danish Society for Internal Medicine.
