Would you like to be a general practitioner? Baseline findings of a longitudinal survey among Danish medical trainees.

BACKGROUND: Recruiting and securing primary care physician workforce has been the center of international attention for decades. In Denmark, the number of general practitioners has decreased by 8.5% since 2013. However, a rising population age and increasing prevalence of chronic diseases and multimorbidity place an even greater future need for general practitioners in Denmark. The choice of general practice as specialty has been associated with a range of both intrinsic and extrinsic factors, however, few studies have examined the recruitment potential that lies within medical trainees' who are undecided about general practice specialization. The aim of this study was, therefore, to explore how medical trainees who are undecided about general practice specialization (GP-positive/undecided) differ from medical trainees who are either committed (GP-committed) or not committed to a general practice career (GP-non-committed) regarding factors related to future work life. METHODS: The present study concerns baseline findings from a longitudinal survey study. An online questionnaire was e-mailed to a national cohort of medical trainees during their transition from under- to postgraduate education. The associations between orientations towards general practice specialization and work-related factors and potential influencing factors, respectively, were analyzed using uni- and multivariable modified Poisson regression models. RESULTS: Of 1,188 invited participants, 461 filled out key study variables concerning specialty preferences and rejections, corresponding to a response rate of 38.8%. We found significant positive associations between GP-positive/undecided orientation and valuing a good work/life balance and the opportunity to organize own working hours when compared to GP-non-committed respondents. Compared to the GP-committed orientations, the GP-positive/undecided orientation was associated with a positive attitude towards technology, working shift hours, and an openness towards several career paths. Across all orientations, undergraduate exposure to the specialties was found to be highly influential on the specialty preferences. CONCLUSION: GP-positive/undecided medical trainees value autonomy over their working hours more than the GP-non-committed, but less than the GP-committed. However, the GP-positive/undecided respondents present more openness to different career opportunities and the use of technology in daily work. We suggest using this knowledge in the planning of recruitment strategies aiming to increase interest in general practice specialization.

The impact of short-course hypofractionated radiotherapy on multimodality treatment utilisation, compliance, and outcome in glioblastoma patients: a Danish patterns of care study.

BACKGROUND: The aim of this retrospective registry-based Danish patterns of care study was (1) to evaluate the real-world utilisation of short-course hypofractionated radiotherapy (HFRT) in glioblastoma (GBM) patients over time, and (2) to evaluate the impact of short-course HFRT by assessing trends in multimodality treatment utilisation, compliance, and outcome. MATERIAL AND METHODS: Data of all adults with newly diagnosed pathology-confirmed GBM between 2011 and 2019 were extracted from the nationwide Danish Neuro-Oncology Registry. Short-course HFRT was defined as a fraction size of > 2 Gy to a planned dose of > 30 Gy. Patterns of care were assessed. To analyse trends in the assignment to short-course HFRT, and in radiotherapy (RT) compliance, multivariable logistic regression was applied. To analyse trends in survival, multivariable Cox regression was used. RESULTS: In this cohort of 2416 GBM patients, the utilisation of short-course HFRT significantly increased from ca. 10% in 2011 to 33% in recent years. This coincided with the discontinued use of palliative regimens and a decreased use of conventional fractionation. The proportion of patients proceeding to RT remained stable at ca. 85%. The proportion of patients assigned to chemoradiotherapy (CRT) remained stable at ca. 60%; the use of short-course hypofractionated CRT increased with ca. 10%, while the use of conventionally fractionated CRT decreased with ca. 10%. Compliance with conventionally fractionated and short-course HFRT was respective 92% and 93%, and significantly increasing in recent years. In the complete cohort, the median overall survival remained stable at ca. 11 months. Assignment to short-course HFRT was independently associated with shorter survival. CONCLUSION: In Denmark, the use of short-course HFRT significantly increased in recent years. Nonetheless, the overall utilisation of RT and chemotherapy did not increase on a population level. Nor did survival change. In contrast, compliance with both conventionally fractionated RT and short-course HFRT increased.

A national study on the inter-observer variability in the delineation of organs at risk in the brain.

BACKGROUND: The Danish Neuro Oncology Group (DNOG) has established national consensus guidelines for the delineation of organs at risk (OAR) structures based on published literature. This study was conducted to finalise these guidelines and evaluate the inter-observer variability of the delineated OAR structures by expert observers. MATERIAL AND METHODS: The DNOG delineation guidelines were formed by participants from all Danish centres that treat brain tumours with radiotherapy. In a two-day workshop, guidelines were discussed and finalised based on a pilot study. Following this, the ten participants contoured the following OARs on T1-weighted gadolinium enhanced MRI from 13 patients with brain tumours: optic tracts, optic nerves, chiasm, spinal cord, brainstem, pituitary gland and hippocampus. The metrics used for comparison were the Dice similarity coefficient (Dice), mean surface distance (MSD) and others. RESULTS: A total of 968 contours were delineated across the 13 patients. On average eight (range six to nine) individual contour sets were made per patient. Good agreement was found across all structures with a median MSD below 1 mm for most structures, with the chiasm performing the best with a median MSD of 0.45 mm. The Dice was as expected highly volume dependent, the brainstem (the largest structure) had the highest Dice value with a median of 0.89 whereas smaller volumes such as the chiasm had a Dice of 0.71. CONCLUSION: Except for the caudal definition of the spinal cord, the variances observed in the contours of OARs in the brain were generally low and consistent. Surface mapping revealed sub-regions of higher variance for some organs. The data set is being prepared as a validation data set for auto-segmentation algorithms for use within the Danish Comprehensive Cancer Centre - Radiotherapy and potential collaborators.

OptimalTTF-1: Enhancing tumor treating fields therapy with skull remodeling surgery. A clinical phase I trial in adult recurrent glioblastoma.

BACKGROUND: Preclinical studies suggest that skull remodeling surgery (SR-surgery) increases the dose of tumor treating fields (TTFields) in glioblastoma (GBM) and prevents wasteful current shunting through the skin. SR-surgery introduces minor skull defects to focus the cancer-inhibiting currents toward the tumor and increase the treatment dose. This study aimed to test the safety and feasibility of this concept in a phase I setting. METHODS: Fifteen adult patients with the first recurrence of GBM were treated with personalized SR-surgery, TTFields, and physician's choice oncological therapy. The primary endpoint was toxicity and secondary endpoints included standard efficacy outcomes. RESULTS: SR-surgery resulted in a mean skull defect area of 10.6 cm2 producing a median TTFields enhancement of 32% (range 25-59%). The median TTFields treatment duration was 6.8 months and the median compliance rate 90%. Patients received either bevacizumab, bevacizumab/irinotecan, or temozolomide rechallenge. We observed 71 adverse events (AEs) of grades 1 (52%), 2 (35%), and 3 (13%). There were no grade 4 or 5 AEs or intervention-related serious AEs. Six patients experienced minor TTFields-induced skin rash. The median progression-free survival (PFS) was 4.6 months and the PFS rate at 6 months was 36%. The median overall survival (OS) was 15.5 months and the OS rate at 12 months was 55%. CONCLUSIONS: TTFields therapy combined with SR-surgery and medical oncological treatment is safe and nontoxic and holds the potential to improve the outcome for GBM patients through focal dose enhancement in the tumor.

The effect of feedback to general practitioners on quality of care for people with type 2 diabetes. A systematic review of the literature.

BACKGROUND: There have been numerous efforts to improve and assure the quality of treatment and follow-up of people with Type 2 diabetes (PT2D) in general practice. Facilitated by the increasing usability and validity of guidelines, indicators and databases, feedback on diabetes care is a promising tool in this aspect. Our goal was to assess the effect of feedback to general practitioners (GPs) on the quality of care for PT2D based on the available literature. METHODS: Systematic review searches were conducted using October 2008 updates of Medline (Pubmed), Cochrane library and Embase databases. Additional searches in reference lists and related articles were conducted. Papers were included if published in English, performed as randomized controlled trials, studying diabetes, having general practice as setting and using feedback to GPs on diabetes care. The papers were assessed according to predefined criteria. RESULTS: Ten studies complied with the inclusion criteria. Feedback improved the care for PT2D, particularly process outcomes such as foot exams, eye exams and Hba1c measurements. Clinical outcomes like lowering of blood pressure, Hba1c and cholesterol levels were seen in few studies. Many process and outcome measures did not improve, while none deteriorated. Meta analysis was unfeasible due to heterogeneity of the studies included. Two studies used electronic feedback. CONCLUSION: Based on this review, feedback seems a promising tool for quality improvement in diabetes care, but more research is needed, especially of electronic feedback.

[Tumor treating fields in cancer treatment in Denmark].

Tumor treating fields (TTFields) is a new non-invasive approach to cancer treatment. TTFields is low-intensity (1-5 V/m), intermediate frequency (150-200 kHz) alternating electric fields delivered locally to the tumour to selectively kill dividing cells and disrupt cancer growth. TTFields has proven safe and effective for newly diagnosed glioblastoma and is currently being tried for multiple other tumours. This review presents an introduction to TTFields, covering the main indications, the application method, the mechanism of action, the clinical results and the perspectives for implementation in Danish cancer treatment.

Suboptimal quality of type 2 diabetes care discovered through electronic feedback led to increased nurse-GP cooperation. A qualitative study.

AIM: To understand the influence of electronic feedback system (EFS) on providing type 2 diabetes care in general practice using a qualitative approach embedded in a randomized controlled trial. METHOD: All 160 general practitioners (GPs) randomized to receive EFS were invited. Thirteen GPs from two solo and two partnership practices were interviewed about their experience with the EFS which provided data on the quality of diabetes care in their practices. Data was analysed using a qualitative descriptive approach. RESULTS: All participants found the insight into the overall quality of their diabetes care beneficial. While the two solo practices reported of no changes, the EFS catalysed organisational changes in the two partnership practices by allocating a number of diabetes controls to nurses. Limited time and a lack of real-time data were main barriers towards using the system. CONCLUSION: EFS used at an overall level provided an overview of the diabetes population which made GPs aware of the need to improve the quality of diabetes care. The EFS influenced partnership practices, but not solo practices, to hire nurses and allocate parts of diabetes care to them. The findings are important in the interpretation of the effect of EFS.
