- Few studies have assessed healthcare resource utilization (HRU) in patients with Philadelphia-negative myeloproliferative neoplasms (MPN) using a matched cohort design. Further, no detailed assessment of HRU in the years preceding an MPN diagnosis exists. We conducted a registry-based nationwide Danish cohort study, including patients with essential thrombocythemia, polycythemia vera, myelofibrosis, and unclassifiable MPN diagnosed between January 2010 and December 2016. HRU data were summarized annually from 2 years before MPN diagnosis until emigration, death, or end of study (December 2017). We included 3342 MPN patients and 32 737 comparisons without an MPN diagnosis, matched on sex, age, region of residence, and level of education. During the study period, the difference in HRU (rate ratio) between patients and matched comparisons ranged from 1.0 to 1.5 for general practitioner contacts, 0.9 to 2.2 for hospitalizations, 0.9 to 3.8 for inpatient days, 1.0 to 4.0 for outpatient visits, 1.3 to 2.1 for emergency department visits, and 1.0 to 4.1 for treatments/examinations. In conclusion, MPN patients had overall higher HRU than the matched comparisons throughout the follow-up period (maximum 8 years). Further, MPN patients had substantially increased HRU in both the primary and secondary healthcare sector in the 2 years preceding the diagnosis.

- BACKGROUND: Myeloproliferative neoplasms (MPNs) are characterized by a substantial symptom burden, risk of debilitating complications (e.g., thrombosis), and increased comorbidity. Recently, three comprehensive questionnaire studies (Mesa 2016, Harrison 2017, Jingbo 2018) have reported a high impact of MPNs on patients' ability to work. However, no registry-based studies have assessed labor market attachment (LMA) of MPN patients and matched nonMPN comparisons.AIM: To assess the pre- and post-diagnostic LMA of MPN patients and matched nonMPN comparisons.METHODS: We conducted a descriptive, registry-based nationwide cohort study, using data from the Danish National Chronic Myeloid Neoplasia Registry including all Danish MPN patients diagnosed between January 2010 and December 2016. Population-based cohorts of nonMPN comparisons were constructed by 1:10 matching on age, sex, level of education, and region of residence. Data on LMA were retrieved from the Danish Register for Evaluation of Marginalization, which holds information on all public transfer payments in Denmark. Data were linked using the unique civil registration number, which identifies all Danish citizens. The LMA endpoints were defined for each individual as working (not receiving any type of transfer payment), unemployed, receiving transfer payment for either sick leave, disability pension, age pension, or other health-related benefits (e.g., wage-subsidized employment). We assessed LMA weekly for each individual from two years before diagnosis until death, emigration, or two years after the diagnosis. For each cohort, we presented LMA as proportions with 95% confidence intervals (CIs), as well as the proportion of individuals who died during follow-up.RESULTS: The study included 3,342 MPN patients (1,140 essential thrombocythemia [ET]; 1,109 polycythemia vera [PV]; 533 myelofibrosis [MF]; and 560 unspecified MPN [MPN-U]) and 32,737 nonMPN comparisons (11,181 nonET; 10,873 nonPV; 5,217 nonPMF; and 5,466 nonMPN-U). The median age at time of diagnosis was: ET 67 years (interquartile range [IQR], 55-76); PV, 69 years (IQR, 61-77); PMF, 73 years (IQR, 66-79); and MPN-U, 72 years (IQR, 63-80).At time of MPN diagnosis, the majority of MPN patients and nonMPN comparisons received age pension (range: ET, 52.1% [95% CI, 49.2-55.0] to nonMF, 70.3% [95% CI, 69.1-71.6]). The proportions working were: ET, 35.1% (95% CI, 32.3-37.9) vs. nonET, 37.3% (95% CI, 36.5-38.2); PV, 22.6% (95% CI, 20.2-25.1) vs. nonPV, 30.8% (95% CI, 29.9-31.7); MF, 23.8% (95% CI, 20.2-27.4) vs. nonMF, 23.6% (95% CI, 22.5-24.8); and MPN-U, 22.1% (95% CI,18.7- 25.6) vs. nonMPN-U, 27.8% (95% CI, 26.6-29.0). Across MPN subtypes, a larger proportion of patients than comparisons were on sick leave: ET, 3.5% (95% CI, 2.4-4.6) vs. nonET, 1.3% (95% CI, 1.1-1.5); PV, 5.5% (95% CI, 4.2-6.8) vs. nonPV, 0.9% (95% CI, 0.7-1.1); MF (not applicable due to small numbers) vs. nonMF, 0.6% (95% CI, 0.4-0.8); and MPN-U, 3.0% (95% CI, 1.6- 4.5) vs. nonMPN-U, 1.0% (95% CI, 0.7-1.3). Regarding disability pension, the proportions ranged from 4.1% (95% CI, 2.4-5.8) to 5.0% (95% CI, 3.7-6.3) among patients and from 3.1% (95% CI, 2.6-3.6) to 4.7% (95% CI, 4.3-5.1) among comparisons. For both MPN patients and nonMPN comparisons, few were unemployed (≤3.3%) or received other health-related benefits (≤1.6%).Two years preceding diagnosis, the proportion of PV and MPN-U patients working was slightly lower than the matched comparisons: PV, 31.0% (95% CI, 28.4-33.8) vs. nonPV, 34.3% (95% CI, 33.5-35.2) and MPN-U, 28.2% (95% CI, 24.6-32.1) vs. nonMPN-U, 32.0% (95% CI, 30.7-33.2), while this difference was not observed between ET and MF patients and their respective comparisons.From two years before to two years after diagnosis, we observed slightly larger reductions in the proportion working among MPN patients than among comparisons. Among MPN patients, the proportion on sick leave including other health-related benefits, increased during the study period, while it remained unchanged among comparisons. The proportion of patients and comparisons on disability pension remained stable.CONCLUSION: Overall, our findings showed that Danish patients with ET, PV, MF, and MPN-U had slightly impaired LMA already two years before diagnosis and up to two years after diagnosis. Thus, fewer patients were working and more patients transferred to sick leave compared with matched individuals without MPN.

- Background: Patients with myeloproliferative neoplasms (MPNs) suffer from substantial symptoms and risk of debilitating complications, yet observational data on their labor market affiliation are scarce.Material and methods: We conducted a descriptive cohort study using data from Danish nationwide registries, including patients diagnosed with MPN in 2010-2016. Each patient was matched with up to ten comparators without MPN on age, sex, level of education, and region of residence. We assessed pre- and post-diagnosis labor market affiliation, defined as working, unemployed, or receiving sickness benefit, disability pension, retirement pension, or other health-related benefits. Labor market affiliation was assessed weekly from two years pre-diagnosis until death, emigration, or 31 December 2018. For patients and comparators, we reported percentage point (pp) changes in labor market affiliation cross-sectionally from week −104 pre-diagnosis to week 104 post-diagnosis.Results: The study included 3,342 patients with MPN and 32,737 comparators. From two years pre-diagnosis until two years post-diagnosis, a larger reduction in the proportion working was observed among patients than comparators (essential thrombocythemia: 10.2 [95% CI: 6.3–14.1] vs. 6.8 [95% CI: 5.5–8.0] pp; polycythemia vera: 9.6 [95% CI: 5.9–13.2] vs. 7.4 [95% CI: 6.2–8.7] pp; myelofibrosis: 8.1 [95% CI: 3.0–13.2] vs. 5.8 [95% CI: 4.2–7.5] pp; and unclassifiable MPN: 8.0 [95% CI: 3.0–13.0] vs. 7.4 [95% CI: 5.7–9.1] pp). Correspondingly, an increase in the proportion of patients receiving sickness benefits including other health-related benefits was evident around the time of diagnosis.Conclusion: Overall, we found that Danish patients with essential thrombocythemia, polycythemia vera, myelofibrosis, and unclassifiable MPN had slightly impaired labor market affiliation compared with a population of the same age and sex. From two years pre-diagnosis to two years post-diagnosis, we observed a larger reduction in the proportion of patients with MPN working and a greater proportion receiving sickness benefits compared with matched individuals.
