[Cohort study on the experiences of cancer diagnosis and treatment in Iceland in the year 2015-2019].

INTRODUCTION: In the coming years, an increase in the number of cancer cases can be expected in Iceland. It is important to gain more insight into the experiences of the diagnostic- and treatment phase among those diagnosed with cancer to improve quality of life and life expectancy. METHODS: The study included 4575 individuals diagnosed with cancer between 2015 and 2019 in Iceland, 18 years or older at the time. Participants answered an on-line questionnaire once between 2020 and 2021. RESULTS: A total of 1672 (37%) individuals responded to the questionnaire. The mean age at diagnosis was 59 years (±12). The majority of participants were informed on their cancer diagnosis during a doctor's appointment (67%), but a quarter (25%) received the information by telephone. A total of 77% of participants were satisfied with the diagnostic process, thereof relatively fewer women than men (73% vs. 83%) (p<0,001). Fewer of those who received the cancer diagnosis by telephone were pleased with the diagnostic process (62%) compared with those receiving information during a doctor's appointment (85%) (p<0,001). More women (58%) than men (33%) expressed the need for support regarding mental well-being from healthcare professionals during the diagnostic process (p<0.001). In 2015, 36% of participants started treatment more than month after diagnosis, compared with 51% in 2019. The need for various specific resources during treatment, e.g. physiotherapy, psychological services or nutritional counseling were regularly assessed among 20-30% of participants. CONCLUSION: A quarter of respondents diagnosed with cancer received information about the diagnosis over the phone instead of an interview. There is a suggestion that the time from diagnosis to the start of cancer treatment is increasing. It is necessary to assess whether it is possible to support individuals with cancer better during the diagnostic- and treatment phase based on their individual needs.

Medication use in populations exposed to the 2010 Eyjafjallajökull eruption: an interrupted time series analysis.

OBJECTIVES: To assess the trends in medication use indicative of physical and psychological morbidity following the 2010 volcanic eruption in Eyjafjallajökull immediately after and during a 3-year period following the eruption. DESIGN: Population-based register study. SETTING: Eyjafjallajökull eruption in Iceland, 2007-2013. PARTICIPANTS: All residents in Iceland who received at least one medication dispensing were identified. Residents of exposed areas were classified into exposure groups (individual-level data) and residents in other parts of Iceland were included as a non-exposed group (aggregated data). INTERVENTION/EXPOSURE: Eyjafjallajökull erupted on 14 April 2010 and continued for 39 days, producing heavy ash fall in South Iceland. MAIN OUTCOME MEASURES: Using interrupted time series analysis, we examined annual and quarterly changes in medicine use, measured as number of dispensed defined daily dose (DDD) per 1000 individuals. We calculated the level shift (immediate change) and change in slope from pre-eruption to post-eruption (long-term change) in medication dispensing. RESULTS: Among exposed residents, there was a 6% decrease (95% CI -7% to -4%) in the annual number of dispensed DDDs 1-year post-eruption in the overall medication class, including analgesics (-5%, 95% CI -6% to -3%), hypnotics and sedatives (-9%, 95% CI -11% to -7%) and respiratory medications (-7%, 95% CI -9% to -5%; -8%, 95% CI -11% to -4%). Simultaneously, there was a 9% decrease (95% CI -14% to -4%) in the overall medication class among non-exposed residents. Moreover, among exposed residents, we observed change in slope of -4% (95% CI -7% to -1%) in the overall medication class, including for analgesics (-6%, 95% CI -8% to -3%) and other respiratory drugs (-10%, 95% CI -16% to -4%). CONCLUSION: Our findings indicate that the eruption did not lead to increases in medication dispensing among residents of exposed areas, rather decreases for some medicine classes. The results should be interpreted with caution since the content of each eruption differs.
