Background Early diagnosis is crucial for the treatment of childhood cancer as it in some cases can prevent progression of disease and improve prognoses. However, childhood cancer can be difficult to diagnose and barriers to early diagnosis are multifactorial. New knowledge about factors influencing the pathway to diagnosis contribute to a deeper understanding of the mechanisms that influence this time span. Qualitative research in the field is sparse but can be expected to lead to additional useful insights that could contribute to efforts shorten time to diagnosis. The purpose of this study was to explore parents’ experiences of the pathway to diagnosis in the time between their noticing bodily or behavioural changes and their child’s diagnosis. Methods The study is a qualitative interview study carried out in large Danish hospital. Thirty-two interviews with a total of 46 parents of children with cancer were included for analysis. The children were diagnosed with haematological cancers (n = 17), solid tumours (n = 9) or brain tumours (n = 6). Data were analysed applying the theoretical model of pathways to treatment and an inductive-deductive approach. A revised ‘diagnostic triage’ model was developed and validated by member checking. Results The pathway to diagnosis was influenced by various factors which we present as consistent parts of a new diagnostic triage model. Each factor impacts the level of urgency assigned to bodily and behavioural changes by parents, general practitioners and specialists. The model of diagnostic triage was developed and validated to understand mechanisms influencing time from the point parents notice changes in their child to diagnosis. The model identifies dynamic movement between parental triage in everyday life and professional triage in a healthcare system, both affecting appraisal and case escalation according to: 1) the nature of bodily and behavioural changes, 2) parental intuition, 3) social relations, 4) professional-child-parent interaction, and 5) specialist-child-parent interaction. Conclusions Diagnostic triage is a model which explains mechanisms that shape the pathway to diagnosis. It is a contribution aimed at supporting the clinical diagnostic process, that ultimately could ensure more timely testing, referral and diagnosis, and also a novel theoretical framework for future research on diagnostic pathways.

A Danish decision support system (DSS) on integrated pest management (including pathogens and weeds) has been developed during the past 20 years. This DSS is distributed as an integrated part of the ‘Danish Integrated Farm Management System’, which is a PC program, of which the plant protection module presently has about 2500 subscribers in Denmark. This program has been designed to propose relevant options for treatment with plant protection products according to observations from a field inspection. The new object‐oriented web‐based system architecture of this DSS was developed in 2001. This allows local (national) adaptation of the DSS in terms of language, crops, pests, products and features. Model complexity and DSS algorithms can also be adjusted to local conditions. The system has been implemented in a relational database structure (Microsoft SQL Server) and a dynamic web application (Java and Jscript in Active Server Pages on an Internet Information Server). The system architecture has been designed with emphasis on a high level of flexibility for future adjustments due to agronomic and legal requirements. The DSS models have been linked to a pest identification module and to a comprehensive database on label information on plant protection products.

Background While underlying mechanisms and pathways of social inequalities in cancer survival have been extensively examined in adults, this is less so for children with cancer. Hypothesized mechanisms include prediagnostic utilization of and navigation through the health care system, which may differ by socioeconomic resources of the families. In this nationwide register-based study we investigated the association between measures of family socioeconomic position in relation to prediagnostic health care contacts and stage of disease at diagnosis in children with cancer in Denmark. Methods We identified all children diagnosed with a cancer at ages 0–15 years in 1998–2016 (N = 3043) from the Danish Childhood Cancer Registry. We obtained comprehensive information on measures of socioeconomic position, parental health and prediagnostic contacts to both general practitioners and hospitals 24 months prior to diagnosis from various national registries. We fitted multivariable conditional logistic regression models for the association of family socioeconomic and health-related variables with firstly, frequent health care contacts and secondly, advanced stage. Results We found higher odds ratios (OR) of frequent both overall and emergency health care contacts in the last 3 months before diagnosis in children from households with short parental education and mixed affiliation to work market, when compared to children with high family socioeconomic position. Further, children of parents with depression or of non-Western origin, respectively, had higher OR for frequent overall and emergency contacts. We found no association between socioeconomic position, parental health and stage of disease. Conclusion Families with socioeconomic disadvantage, non-Western origin or depression more frequently utilize prediagnostic health care services, both generally and in the acute setting, indicating that some disadvantaged families may struggle to navigate the health care system when their child is sick. Reassuringly, this was not reflected in disparities in stage at diagnosis. In order to improve the diagnostic process and potentially reduce health care contacts, attention and support should be given to families with a high number of health care contacts over a short period of time.

Background: Socioeconomic differences in survival among children with acute lymphoblastic leukemia (ALL) have been reported in high-income countries and there is an unmet need for strategies to identify vulnerable patient subgroups. Reported differences in survival for children from families with different socioeconomic positions seem to arise when starting maintenance therapy. This could reflect reduced physician's compliance or family adherence to maintenance therapy.Methods: This nationwide cohort study with extensive monitoring of systemic methotrexate (MTX)/6-mercaptopurine (6MP) dosing and metabolite levels, retrospectively investigated 173 Danish children treated according to The Nordic Society
