Under-Reporting of Self-Reported Medical Conditions in Aviation: A Cross-Sectional Survey
BACKGROUND: The applicantsâ self-declaration of medical history is crucial for safety. Some evidence indicates that under-reporting of medical conditions exists. However, the magnitude in a population of aviation personnel has not been reported earlier.
METHODS: A total of 9941 applicants for medical certificate/attestation for aviation-related safety functions during the last 5 yr up to December 2019 were registered at the Civil Aviation Authority Norway. E-mail addresses were known for 9027 of these applicants, who were invited to participate in a web-based survey.
RESULTS: Among the 1616 respondents, 726 (45%) were commercial pilots, 457 (28%) private pilots, 272 (17%) air traffic controllers, and the remaining were cabin crew or crew in aerodrome/helicopter flight information service (AFIS or HFIS, respectively). A total of 108 were initial applicants. The age group 50+ constituted the largest proportion of respondents (53%). Aeromedical certification in general was believed to improve flight safety âto a highâ or âvery high extentâ by 64% of the respondents. A total of 188 individuals (12%) admitted having under-reported information related to one or more categories, including mental (3%) or physical health (4%), medications (2%), and drug use, including alcohol use (5%). Among these, 21 participants believed their own under-reporting âto someâ or âto a high extentâ affected flight safety. In total 50% of noninitial applicants reported that they knew colleagues who had under-reported information. Analyses revealed that being a commercial pilot showed a higher risk for under-reporting compared with other classes and the perception of aeromedical examiners in a supportive or authoritative role reduced the risk.
CONCLUSIONS: Under-reporting of medical conditions could be significant in aviation. Further studies should be conducted to investigate the true extent of under-reporting and its impact on flight safety and what mitigating measures might be recommended
Achieving Thoracic Oncology data collection in Europe: a precursor study in 35 Countries
Background: A minority of European countries have participated in international comparisons with high level data on lung cancer. However, the nature and extent of data collection across the continent is simply unknown, and without accurate data collection it is not possible to compare practice and set benchmarks to which lung cancer services can aspire.Methods: Using an established network of lung cancer specialists in 37 European countries, a survey was distributed in December 2014. The results relate to current practice in each country at the time, early 2015. The results were compiled and then verified with co-authors over the following months.Results: Thirty-five completed surveys were received which describe a range of current practice for lung cancer data collection. Thirty countries have data collection at the national level, but this is not so in Albania, Bosnia-Herzegovina, Italy, Spain and Switzerland. Data collection varied from paper records with no survival analysis, to well-established electronic databases with links to census data and survival analyses.Conclusion: Using a network of committed clinicians, we have gathered validated comparative data reporting an observed difference in data collection mechanisms across Europe. We have identified the need to develop a well-designed dataset, whilst acknowledging what is feasible within each country, and aspiring to collect high quality data for clinical research

Age-related treatment patterns for stage I NSCLC in three European countries
Introduction: Surgery is the preferred treatment for patients with early-stage non-small cell lung cancer (NSCLC) while stereotactic body radiation therapy (SBRT) may be applied in patients with major comorbidity or high age. We evaluated the association between age and treatment utilization for early-stage NSCLC in patients diagnosed in 2015â2016 in three European countries. Patients and methods: Information was retrieved from population-based registries in England, Norway and the Netherlands. Treatment patterns and two-year overall survival rates for 105,124 patients with clinical stage I were analysed by age-group. Results: Surgical resection rates were higher in Norway (55%) and England (53%) than in the Netherlands (47%), and decreased with increasing age. SBRT use was highest in the Netherlands (41%), followed by Norway (29%) and England (12%). In the Netherlands, SBRT was the prevailing treatment in patients aged 70 years or older. In octogenarians, the proportion not receiving curative intent treatment was 53% in England, versus 35% in Norway and 22% in the Netherlands. Two-year survival rates were better for surgery than for SBRT and slightly better in Norway. Conclusion: In patients aged 70 years or older, the proportion not receiving any curative treatment remains substantial, and differs significantly between countries. Measures to address these disparities are needed
Factors associated with delayed treatment initiation in an unselected cohort of patients with small-cell lung cancer
Background
Small-cell lung cancer (SCLC) is an aggressive, rapidly progressive malignancy. Thus, expedient diagnosis and treatment initiation is important. This study identifies and quantifies factors associated with delayed diagnosis and treatment initiation in patients with SCLC and compares time to treatment in SCLC with a cohort of patients with non-small cell lung cancer (NSCLC).
Materials and Methods
The study included all patients diagnosed with SCLC at a hospital in southern Norway in a ten-year period (2007â2016), and all NSCLC patients during the period 2013â2016. Total time to treatment (TTT), was defined as the number of days from date of referral due to suspicion of lung cancer to first day of treatment. Factors associated with prolonged TTT were estimated using multivariate median regression analysis.
Results
The median TTT and interquartile range (IQR) for the 183 patients with SCLC was 16 (10â23) days. Factors associated with delayed TTT included outpatient versus inpatient evaluation (+8.4 days), number of diagnostic procedures (+4.3 days per procedure), stage I-III versus stage IV (+3.6 days) and age (+2.1 days per 10 years). In 2013â16, TTT in SCLC was 3.5 days shorter than in the period before and less than half that of NSCLC in the same period, 15 (9â22) versus 33 (22â50) days (p = 0.001).
Conclusion
Shorter TTT is seen in higher stage, while longer TTT is a result of increasing complexity of the diagnostic process and treatment decisions of patients with curative intent treatment. Knowledge on delaying factors can shorten TTT and improve clinical practice

Reduced delays in diagnostic pathways for non-small cell lung cancer after local and National initiatives
Objectives
Patients with non-small cell lung cancer (NSCLC) may experience progression and stage shift due to delays in a complex and time-consuming diagnostic work-up. We have analyzed the impact of both a local and national intervention on total time to treatment (TTT).
Material and Methods
All patients diagnosed with NSCLC at a Norwegian county hospital from 2007 to 2016 were reviewed. Logistic bottlenecks and delays were identified (2007â12) resulting in implementation of a local initiative with new diagnostic algorithm introduced by the beginning of 2013. In 2015, national diagnostic cancer pathways were implemented. TTT defined as time from received referral from the primary physician to start of treatment was compared in the three diagnostic time periods; baseline (2007â12), local (2013â14) and national (2015â16).
Results
A total of 780 patients were included. Among patients treated with curative intent the median TTT decreased by 21 days, from 64 to 43 days (p < 0.001) while the mean number of diagnostic procedures increased from 3.5 to 3.9. In median regression analysis, the local initiative was associated with a reduction of estimated 7.8 days (95% CI 3.2, 12.3) in TTT, while the national initiative correlated with a reduction of estimated 14.9 days (95% CI 10.2, 19.6) compared to time at baseline. Covariates associated with longer TTT were stage I, use of PET-CT, diagnostic procedure at external hospital, and number of diagnostic procedures.
Conclusion
Local and national initiatives significantly reduced TTT in NSCLC. The effect was most pronounced among patients with disease available for curative treatment
