The epidemiology and societal costs of myasthenia gravis in Norway: A non-interventional study using national registry data.

BACKGROUND AND PURPOSE: With the emergence of new treatment options for myasthenia gravis (MG), there is a need for information regarding epidemiology, healthcare utilization, and societal costs to support economic evaluation and identify eligible patients. We aimed to enhance the understanding of these factors using nationwide systematic registry data in Norway. METHODS: We received comprehensive national registry data from five Norwegian health- and work-related registries. The annual incidence and prevalence were estimated for the period 2013-2021 using nationwide hospital and prescription data. The direct, indirect (productivity losses) and intangible costs (value of lost life-years [LLY] and health-related quality of life [HRQoL]) related to MG were estimated over a period of 1 year. RESULTS: In 2021, the incidence of MG ranged from 15 to 16 cases per year per million population depending on the registry used, while the prevalence varied between 208.9 and 210.3 per million population. The total annual societal costs of MG amounted to EUR 24,743 per patient, of which EUR 3592 (14.5%) were direct costs, EUR 8666 (35.0%) were productivity loss, and EUR 12,485 (50.5%) were lost value from LLY and reduced HRQoL. CONCLUSION: The incidence and prevalence of MG are higher than previously estimated, and the total societal costs of MG are substantial. Our findings demonstrate that productivity losses, and the value of LLY and HRQoL constitute a considerable proportion of the total societal costs.

Pragmatic randomized controlled trial comparing a complex telemedicine-based intervention with usual care in patients with chronic conditions.

This study evaluates a complex telemedicine-based intervention targeting patients with chronic health problems. Computer tablets and home telemonitoring devices are used by patients to report point-of-care measurements, e.g., blood pressure, blood glucose or oxygen saturation, and to answer health-related questions at a follow-up center. We designed a pragmatic randomized controlled trial to compare the telemedicine-based intervention with usual care in six local centers in Norway. The study outcomes included health-related quality of life (HRQoL) based on the EuroQol questionnaire (EQ-5D-5L), patient experiences, and utilization of healthcare. We also conducted a cost-benefit analysis to inform policy implementation, as well as a process evaluation (reported elsewhere). We used mixed methods to analyze data collected during the trial (health data, survey data and interviews with patients and health personnel) as well as data from national health registers. 735 patients were included during the period from February 2019 to June 2020. One year after inclusion, the effects on the use of healthcare services were mixed. The proportion of patients receiving home-based care services declined, but the number of GP contacts increased in the intervention group compared to the control group. Participants in the intervention group experienced improved HRQoL compared to the control group and were more satisfied with the follow-up of their health. The cost-benefit of the intervention depends largely on the design of the service and the value society places on improved safety and self-efficacy.

Comparative retention and effectiveness of migraine preventive treatments: A nationwide registry-based cohort study.

BACKGROUND AND PURPOSE: Little is known about the comparative effects of migraine preventive drugs. We aimed to estimate treatment retention and effectiveness of migraine preventive drugs in a nationwide registry-based cohort study in Norway between 2010 and 2020. METHODS: We assessed retention, defined as the number of uninterrupted treatment days, and effectiveness, defined as the reduction in filled triptan prescriptions during four 90-day periods after the first preventive prescription, compared to a 90-day baseline period. We compared retention and efficacy for different drugs against beta blockers. Comparative retention was estimated with hazard ratios (HRs), adjusted for covariates, using Cox regression, and effectiveness as odds ratios (ORs) using logistic regression, with propensity-weighted adjustment for covariates. RESULTS: We identified 104,072 migraine patients, 81,890 of whom were female (78.69%) and whose mean (standard deviation) age was 44.60 (15.61) years. Compared to beta blockers, botulinum toxin (HR 0.43, 95% confidence interval [CI] 0.42-0.44) and calcitonin gene-related peptide pathway antibodies (CGRPabs; HR 0.63, 95% CI 0.59-0.66) were the least likely to be discontinued, while clonidine (HR 2.95, 95% CI 2.88-3.02) and topiramate (HR 1.34, 95% CI 1.31-1.37) were the most likely to be discontinued. Patients on simvastatin, CGRPabs, and amitriptyline were more likely to achieve a clinically significant reduction in triptan use during the first 90 days of treatment, with propensity score-adjusted ORs of 1.28 (95% CI 1.19-1.38), 1.23 (95% CI 0.79-1.90), and 1.13 (95% CI 1.08-1.17), respectively. CONCLUSIONS: We found a favorable effect of CGRPabs, amitriptyline, and simvastatin compared with beta blockers, while topiramate and clonidine were associated with poorer outcomes.

Intravitreal anti-vascular endothelial growth factor therapy for retinal diseases in Norway from 2011 to 2021: A combined registry and survey study.

PURPOSE: To investigate the use of intravitreal anti-vascular endothelial growth factor (anti-VEGF) therapy in Norway from 2011 to 2021 and explore how the eye departments organized their injection services. METHODS: We combined data from the Norwegian Patient Registry (NPR) with survey responses from Norway's 22 eye departments. The NPR data encompassed all registered intravitreal injection episodes from 2011 to 2021. The survey contained questions about local treatment practices and emphasized neovascular age-related macular degeneration (nAMD), retinal vein occlusion and diabetic macular edema. RESULTS: A total of 47247 unique patients received 841 646 intravitreal injections in the study period. The number of patients per year increased from 6522 in 2011 to 20 635 in 2021. The number of injections per year increased from 30 926 in 2011 to 125 258 in 2021. The most frequent diagnosis was nAMD. In 2021, the age-adjusted treatment activity in Norway's 11 counties ranged from 47.8 to 75.5 injections per 1000 inhabitants aged ≥50 years. The use of aflibercept gradually exceeded bevacizumab, but the aflibercept proportion per county ranged from 38 to 82% in 2021. The survey revealed varying treatment practices, local guidelines were often absent, and only half of the departments defined a lower visual limit for initiating or maintaining treatment. CONCLUSION: The use of intravitreal anti-VEGF therapy increased considerably from 2011 to 2021, but there was considerable regional variation in treatment activity, drug utilization and organization of injection services. These findings emphasize the need for strengthened governance and national guidelines to ensure equal treatment nationally.

Drug-related problems and satisfaction among patients receiving pharmacist-led consultations at the initiation of cardiovascular drugs.

BACKGROUND: Drug-related problems (DRPs) lead to substantial morbidity and mortality and increase healthcare costs. Several interventions have been developed to reduce DRPs and improve the outcome of drug therapy. OBJECTIVE: To investigate DRPs identified through a pharmacist-led intervention and to assess patient satisfaction with the intervention. METHODS: Patients received two pharmacist consultations 1-2 weeks and 3-5 weeks after collecting a new cardiovascular medicine. Information about patient characteristics, beliefs about medicines (BMQ), DRPs, and patient evaluations were collected using questionnaires. RESULTS: Pharmacists identified DRPs among 52.4% and 43.1% of the 633 patients at consultation 1 and 2, respectively. Of the DRPs reported in consultation 1, 43.7% were solved at consultation 2. Among patients with side effects, patients who received advice on managing these in consultation 1 where more likely to have solved problems at consultation 2 (61.2% vs. 42.6%, p = 0.008). Female gender, high BMQ concern and the number of new medicines were associated with DRPs. Patients were highly satisfied with the intervention. Predictors of satisfaction were female gender, older age, higher BMQ necessity, face-to-face consultations, longer duration of consultation 1, and solved problems in consultation 2. CONCLUSIONS: The results indicate that the pharmacist-led follow-up intervention can aid early identification and solving of DRPs in patients prescribed new cardiovascular drugs. Knowledge of factors associated with DRPs and patients' satisfaction may allow further improvement of the intervention.

An economic analysis indicates less strict infection control of COVID-19. / En samfunnsøkonomisk analyse tilsier mindre strenge smitteverntiltak mot covid-19.

The societal burden of the COVID-19 pandemic is hard to determine, but a continuation of the strict infection control measures would be too costly compared to the gains of a lower disease burden, now that a large proportion of the population has been vaccinated.

What are determinants of utilisation of pharmaceutical anticancer treatment during the last year of life in Norway? A retrospective registry study.

OBJECTIVES: The objective of this study was to investigate the use of, and predictors for, pharmaceutical anticancer treatment (PACT) towards the end of a patient's life in a country with a public healthcare system. DESIGN: Retrospective registry study. SETTING: Secondary care in Norway. PARTICIPANTS: All Norwegian patients with cancer (International Classification of Diseases tenth revision (ICD-10) codes C00-99, D00-09, D37-48) in contact with a somatic hospital in Norway between 2009 and 2017 (N=420 655). Analyses were performed on a subsample of decedents with follow-back time of more than 1 year (2013-2017, N=52 496). INTERVENTIONS: N/A. PRIMARY AND SECONDARY OUTCOME MEASURES: Proportion of patients receiving PACT during the last year and month of life. We calculated CIs with block bootstrapping, while predictors of PACT were estimated with logistic regression. RESULTS: 24.0% (95% CI 23.4% to 24.6%) of the patients received PACT during the last year of life and 3.2% (95% CI 3.0% to 3.5%) during their final month. The proportion during the last month was highest for multiple myeloma (12.7%) and breast cancer (6.5%) and lowest for urinary tract (1.1%) and prostate and kidney cancer (1.4%). Patients living in northern (OR 0.80, 95% CI 0.68 to 0.94) and western (OR 0.85, 95% CI 0.75 to 0.96) Norway had lower odds of PACT during the last month, while patients with myeloma (OR 3.0, 95% CI 2.5 to 3.7) and breast (OR 1.4, 95% CI 1.1 to 1.6) had higher odds. Kidney cancer (OR 0.25, 95% CI 0.2. to 0.4), urinary tract (OR 0.38, 95% CI 0.3 to 0.5) and prostate cancer (OR 0.4, 95% CI 0.3 to 0.5) were associated with lower probability of receiving PACT within the last month. CONCLUSIONS: The proportion of patients receiving PACT in Norway is lower than in several other industrialised countries. Age, type of cancer and area of living are significant determinants of variation in PACT.

Phase- and gender-specific, lifetime, and future costs of cancer: A retrospective population-based registry study.

ABSTRACT: Valid estimates of cancer treatment costs are import for priority setting, but few studies have examined costs of multiple cancers in the same setting.We performed a retrospective population-based registry study to evaluate phase-specific (initial, continuing, and terminal phase) direct medical costs and lifetime costs for 13 cancers and all cancers combined in Norway. Mean monthly cancer attributable costs were estimated using nationwide activity data from all Norwegian hospitals. Mean lifetime costs were estimated by combining phase-specific monthly costs and survival times from the national cancer registry. Scenarios for future costs were developed from the lifetime costs and the expected number of new cancer cases toward 2034 estimated by NORDCAN.For all cancers combined, mean discounted per patient direct medical costs were Euros (EUR) 21,808 in the initial 12 months, EUR 4347 in the subsequent continuing phase, and EUR 12,085 in the terminal phase (last 12 months). Lifetime costs were higher for cancers with a 5-year relative survival between 50% and 70% (myeloma: EUR 89,686, mouth/pharynx: EUR 66,619, and non-Hodgkin lymphoma: EUR 65,528). The scenario analyses indicate that future cancer costs are highly dependent on future cancer incidence, changes in death risk, and cancer-specific unit costs.Gender- and cancer-specific estimates of treatment costs are important for assessing equity of care and to better understand resource consumption associated with different cancers.Cancers with an intermediate prognosis (50%-70% 5-year relative survival) are associated with higher direct medical costs than those with relatively good or poor prognosis.

Societal cost of cancer in Norway -Results of taking a broader cost perspective.

BACKGROUND: The broader cost consequences of diseases may be of interest for a wide range of stakeholders. We aimed to estimate all relevant societal costs of cancer and to provide insight into the relative magnitude of the different cost categories. METHOD: We used data from eight different health and work-related registries in Norway. Direct, indirect, and intangible costs (value of lost life years) were estimated over a period of one year with a combination of a top-down and a bottom-up costing approach. RESULTS: The indirect costs (EUR 1,997 million per year) are almost as high as direct costs (EUR 2,154 million), and the value of lost life years and quality of life represents the greatest cost related to cancer (EUR 18,200 million). In addition, cancer is associated with other costs which are commonly omitted from cost-of-illness analyses, including informal nursing (EUR 306 million), patient time costs (EUR 85 million), and excess costs of using public funds (EUR 439 million). Breast and cervical cancer had relatively high work absenteeism costs, while pancreatic and lung cancer had relatively high production costs due to premature deaths. DISCUSSION: Direct health care costs represent small proportions of the total societal costs of cancer. Costs commonly omitted in cost-of-illness analyses represent a significant cost and should be measured and valued in these analyses.

Men receive more end-of-life cancer hospital treatment than women: fact or fiction?

BACKGROUND: An important goal of health care systems is equitable access to health care. Previous research, however, indicates that men receive more cancer care and health care resources than women. The aim of this study was to investigate whether there is a gender difference in terms of end-of-life cancer treatment in hospitals in Norway. MATERIAL AND METHODS: We used nationwide patient-level data from the Norwegian Patient Registry (2013-2017, n = 64,694), and aggregated data from the Norwegian Cause of Death Registry (2013-2018, n = 66,534). We described direct medical costs and utilization of cancer treatment in hospitals (in-patient stays and out-patient clinics) and specialized palliative home care teams by the means of the following variables: gender, type of cancer, age, region of residence, place of death, and use of pharmaceutical anti-cancer treatment last month before death. Generalized linear models with a gamma distribution and log-link function were fitted to identify determinants of direct medical costs in hospital's last year of life. RESULTS: Women aged 0-69 years had an average direct medical cost in hospitals of €26,117 during the last year of life, compared to €29,540 for men, while they were respectively €19,889 and €22,405 for those aged 70 years or older. These gender differences were confirmed in regression models with gender as the only covariate. Adjusted additionally for the type of cancer, the difference was 11%, while including age as a covariate reduced the difference to 6%. When the place of death was also included, the difference was down to 4%. DISCUSSION: The gender difference in hospital costs last year of life can largely be explained by age at death and the proportion dying in hospitals. When adjusting for confounding factors, the differences in end-of-life costs in hospitals are minimal.

Intravitreal therapy for retinal diseases in Norway 2011-2015.

PURPOSE: During the past decade, intravitreally administered biologic drugs have advanced the treatment of retinal diseases, such as wet age-related macular degeneration (AMD), diabetic macular oedema and retinal venous occlusions. The drugs as well as the necessary disease management imply considerable economic burden on healthcare systems. This Norwegian study documents the rates of use of intravitreal therapies and intercounty variation over a 5-year period. METHODS: We collected data from the Norwegian Patient Register for all episodes of care encompassing intravitreal therapy during the period 2011-2015. For each episode, we received information on patient age, sex, county of residence, diagnosis and name of drug injected. RESULTS: During the study period, 21 277 patients had in total 236 857 episodes of care. The number of intravitreal injections doubled from 2011 to 2015, reaching 63 601 injections in 2015, of which 77% were for diagnosed wet AMD. In 2015, the age-adjusted number of episodes varied from 19 to 55 per 1000 population aged 50+ across Norway's 19 counties. The age-adjusted number of patients treated per 1000 population aged 50+ varied from 5.22 to 8.35. CONCLUSION: The use of intravitreal injections increased rapidly with wet AMD as the most frequent diagnosis and with varying utilization across Norway's 19 counties. The causes of the varying use of intravitreal therapies could not be established but may reflect variation in disease prevalence, treatment capacity, travel distance to the nearest ophthalmic service and lack of national treatment guidelines. The geographic variation in utilization may challenge policy goals of equitable care and warrants further studies.

Effect of a pharmacist-led intervention on adherence among patients with a first-time prescription for a cardiovascular medicine: a randomized controlled trial in Norwegian pharmacies.

OBJECTIVE: To examine whether a pharmacist-led intervention improves medication adherence among patients who have filled a first-time prescription for a cardiovascular medicine. METHODS: Design: Unblinded randomized controlled trial. SETTING: 67 Norwegian pharmacies, October 2014-June 2015. PARTICIPANTS: 1480 adults with a first-time prescription for a cardiovascular medicine. INTERVENTION: Participants in the intervention group received two consultations with a pharmacist 1-2 and 3-5 weeks after filling the prescription. Participants in the control group received care according to usual practice. MAIN OUTCOME MEASURE: The primary outcome was self-reported adherence as measured by the 8-item Morisky Medication Adherence Scale (MMAS-8), at 7 and 18 weeks after filling the prescription. Adherence from baseline to week 52 was estimated using data from the Norwegian Prescription Database (NPD). KEY FINDINGS: Data from MMAS-8 showed that 91.3% of the patients in the intervention group were adherent after 7 weeks versus 86.8% in the control group (4.5% difference, 95% CI 0.8-8.2, P = 0.017). The corresponding proportions were 88.7% versus 83.7% after 18 weeks (5.0% difference, 95% CI 0.8-9.2, P = 0.021). NPD data (n = 1294) showed no significant difference in adherence after 52 weeks (95% CI -2.0 to 7.8, P = 0.24). However, adherence among statin users (n = 182) was 66.5% in the intervention group versus 57.4% among new statin users in the general population (n = 1500) (difference 9.1%, 95% CI 1.5-16.0, P = 0.019). CONCLUSION: The main outcome measure indicates that a short, structured pharmacist-led intervention may increase medication adherence for patients starting on chronic cardiovascular medication. However, these findings could not be confirmed by the NPD data analysis.

Nurses' labour supply with an endogenous choice of care level and shift type : a nested discrete choice model with nonlinear income.

It is argued that increasing wages will not only attract more nurses to the health sector, but also increase the number of hours worked for those already there. This article focuses on the response of registered nurses employed in the public sector when they are allowed to endogenously choose between jobs in hospitals and primary care and between day and shift work. A structural labour supply model is estimated on Norwegian micro-data with job-specific wages and hours. The simulation of an overall public wage increase indicates a reduction in total hours. Thus, in contrast to the claim, the income effect seems to dominate in the labour supply of health sector employees.

Public health care with waiting time: the role of supplementary private health care.

We consider an economy where most of the health care is publicly provided, and where there is waiting time for several types of treatments. Private health care without waiting time is an option for the patients in the public health queue. We show that although patients with low waiting costs will choose public treatment, they may be better off with waiting time than without. The reason is that waiting time induces patients with high waiting costs to choose private treatment, thus reducing the cost of public health care that everyone pays for. Even if higher quality (i.e. zero waiting time) can be achieved at no cost, the self-selection induced redistribution may imply that it is socially optimal to provide health care publicly and at an inferior quality level. We give a detailed discussion of the circumstances in which it is optimal to have waiting time for public health treatment. Moreover, we study the interaction between this quality decision and the optimal tax/subsidy on private health care.
