The clinical and economic burden of illness in the first two years after ostomy creation: a nationwide Danish cohort study.

BACKGROUND: Living with an ostomy is often associated with costly complications. This study examined the burden of illness the first two years after ostomy creation. METHODS: Data from Danish national registries included all adult Danes with an ostomy created between 2002 and 2014. RESULTS: Four cohorts consisted, respectively, of 11,385 subjects with a colostomy and 4,574 with an ileostomy, of which 1,663 subjects had inflammatory bowel disease (IBD) and 1,270 colorectal cancer as cause of their ileostomy. The healthcare cost was significantly higher for cases versus matched controls for all cohorts. In the first year, the total healthcare cost per person-year was €27,962 versus €4,200 for subjects with colostomy, €29,392 versus €3,308 for subjects with ileostomy, €15,947 versus €2,216 when IBD was the underlying cause, and €32,438 versus €4,196 when it was colorectal cancer. Healthcare costs decreased in the second year but remained significantly higher than controls. Hospitalization and outpatient services were primary cost drivers, with ostomy-related complications comprising 8-16% of hospitalization expenses. CONCLUSION: Compared to controls, subjects with an ostomy bear a significant health and financial burden attributable to ostomy-related complications, in addition to the underlying disease, emphasizing the importance of better ostomy care to enhance well-being and reduce economic strain.

Health inequities and societal costs for patients with fibromyalgia and their spouses: a Danish cohort study.

OBJECTIVE: To assess the burden of illness of people with fibromyalgia (FM) and their spouses compared with selected match populations in Denmark. METHODS: Population-based, cohort case-control study using data from Danish registries from 1994 to 2021. Individuals with an FM diagnosis were identified from the National Patient Register (2008-2019) and randomly matched to a 1:4 general population comparator. Spouses or persons co-living with subjects with FM at the time of diagnosis were compared with matched comparator spouses. Healthcare and societal costs, socioeconomic status and occurrence of comorbidities were evaluated for subjects with FM, spouses and controls. RESULTS: 9712 subjects with FM (94.9% females, mean age 50 years) and 5946 spouses were included. At year of diagnosis, subjects with FM had significantly more comorbidities compared with controls, including significantly more comorbid rheumatic disorders. The highest risk at the time of FM diagnosis was a comorbid diagnosis of ankylosing spondylitis (OR 7.0, 95% CI 4.9 to 10.0). Significantly more comorbidities were also observed in spouses. Subjects with FM and spouses had higher healthcare and public transfer costs and lower income from employment at all timepoints. Loss of income from employment in subjects with FM occurred years before establishment of the FM diagnosis. The employment rate after diagnosis was 22%. 10 years after the FM diagnosis, 50% received disability pension as compared with 11% of matched controls. The observed net average increased societal cost for subjects with FM amounted to €27 193 per patient-year after diagnosis. CONCLUSION: FM has major health and socioeconomic consequences for patients, their partners and society and call for improved healthcare strategies matching patients' needs.

Economic analyses in cardiac electrophysiology: from clinical efficacy to cost utility.

Cardiac electrophysiology is an evolving field that relies heavily on costly device- and catheter-based technologies. An increasing number of patients with heart rhythm disorders are becoming eligible for cardiac interventions, not least due to the rising prevalence of atrial fibrillation and increased longevity in the population. Meanwhile, the expansive costs of healthcare face finite societal resources, and a cost-conscious approach to new technologies is critical. Cost-effectiveness analyses support rational decision-making in healthcare by evaluating the ratio of healthcare costs to health benefits for competing therapies. They may, however, be subject to significant uncertainty and bias. This paper aims to introduce the basic concepts, framework, and limitations of cost-effectiveness analyses to clinicians including recent examples from clinical electrophysiology and device therapy.

Health care and socioeconomic costs for long-term survivors after implementation of checkpoint-inhibitors and targeted agents for metastatic melanoma.

BACKGROUND: Real-life data on health care costs and loss of productivity after implementing new agents for metastatic melanoma are important to supplement model-based economic data. MATERIALS AND METHODS: All patients registered in the Danish Metastatic Melanoma Database (DAMMED) and the National Patient Registry in 2007-2011 were compared to 2012-2016 after the implementation of checkpoint inhibitors and targeted therapy. Health care costs, social transfer income (STI), and loss of productivity were calculated with a 2-step one model generalised linear regression (GLM) model. Medicine costs were calculated separately. RESULTS: In 2007-2011, 70 (15%) out of 464 patients were long-term survivors compared to 347 (32%) out of 1089 patients in 2012-2016. Total health care costs per patient year were significantly lower in the first treatment year (€41.457 versus €60.547, relative change (RC) 0.72, 95% confidence interval (CI) 0.56-0.94, p = 0.015) and without significant difference the second year in 2012-2016 compared to 2007-2011. Medicine costs per patient year increased the first (€85.464 versus €26.339, RC 3.39, 95% CI 2.61-4.41, p < 0.001) and the second (€26.464 versus €11.150, RC 2.59, 95% CI 1.98-3.40, p < 0.001) year in 2012-2016 compared to 2007-2011. Productivity increased for long-term survivors in 2012-2016 in contrast to 2007-2011. CONCLUSION: Implementation of targeted therapy and checkpoint-inhibitors has increased medicine costs more than three-fold for long-term survivors. Total health care costs excluding medicine costs were significantly lower for long-term survivors the first and without change the second treatment year in 2012-2016 compared to 2007-2011. However, the number of treated patients increased which leads to an increase in overall total health care costs. Importantly, productivity increased for long-term survivors in 2012-2016.

How come Denmark is planning to increase the annual budget for psychiatry by almost 20 percent?

In Denmark, a 10-year plan for psychiatry has been agreed on. The content of the plan was developed in collaboration between the Danish Health Authority and the Danish Authority for Social Services and Housing, and it involved many stakeholders. Recently, the government presented a planned investment that would increase the overall budget in Danish regions and municipalities by almost 20 percent over a 10-year period. Epidemiological research demonstrating shortened life expectancy and high levels of burden of disease for people with mental disorders contributed to emphasizing the need for improvement of psychiatric services. User organizations, trade unions, and scientific societies in the field of mental health were unified in a common organization, called the Psychiatry Alliance, and this alliance agreed on common action points and acted together to influence politicians. An assertive approach toward politicians and media was pivotal, and being a first mover and presenting tentative budgets was very influential.

Burden of illness among intermittent catheter users with non-neurogenic urinary retention in Denmark.

BACKGROUND: Urinary retention (UR) caused by non-neurogenic conditions is a frequent disorder often requiring the use of intermittent catheterization (IC). This study examines the burden of illness among subjects with an IC indication due to non-neurogenic UR. METHODS: Health-care utilization and costs were extracted from Danish registers (2002-2016) related to the first year after IC training and compared to matched controls. RESULTS: A total of 4,758 subjects with UR due to benign prostatic hyperplasia (BPH) and 3,618 subjects with UR due to other non-neurological conditions were identified. Total health-care utilization and costs per patient-year were significantly higher compared to matched controls (BPH: 12,406 EUR vs 4,363, p < 0.000; other non-neurogenic causes: 12,497 EUR vs 3,920, p < 0.000) and driven mainly by hospitalizations. Urinary tract infections (UTIs) were the most frequent bladder complications often requiring hospitalization. The inpatient costs per patient-year for UTIs were significantly higher for cases than controls (BPH: 479 EUR vs 31, p < 0.000; other non-neurogenic causes: 434 EUR vs 25, p < 0.000). CONCLUSIONS: The burden of illness caused by non-neurogenic UR with need for IC was high and essentially driven by hospitalizations. Further research should clarify if additional treatment measures may reduce the burden of illness in subjects suffering from non-neurogenic UR using IC.

Estimates of epilepsy prevalence, psychiatric co-morbidity and cost.

PURPOSE: This study estimated epilepsy prevalence, psychiatric co-morbidity and annual costs associated with epilepsy. METHODS: We used Danish national health registers to identify persons diagnosed with epilepsy and psychiatric disorders, and persons using antiseizure medication and persons using drugs for psychiatric disorders. We calculated the prevalence of epilepsy and co-morbid psychiatric disorders in Denmark on December 31, 2016, using information on epilepsy and psychiatric disorders based on combinations of hospital contacts and use of antiseizure and psychoactive medication. Further, direct and indirect annual costs associated with epilepsy were calculated using individual-level data from a range of socioeconomic registers. RESULTS: There were 5,044,367 persons alive and living in Denmark on December 31, 2016, including 33,628 persons with at least one hospital contact with epilepsy in the previous five years (epilepsy prevalence 0.67% (0.69% males; 0.65% females)). Among these persons with epilepsy, we identified 12,562 (37.4%) persons with a psychiatric disorder or use of drugs used for psychiatric disorders as compared with 801,052 (15.9%) persons in the general population. The estimated total annual individual net costs associated with epilepsy was €30,683. Compared with prevalence estimates on December 31, 2006, the prevalence of epilepsy on December 31, 2016, was slightly higher in the older population and slightly lower in children CONCLUSIONS: Population estimates from national registers provide epilepsy prevalence estimates of approximately 0.6-0.7% - similar to previous reviews of epilepsy prevalence. In addition, the national sample allowed idenitfication of high prevalence of psychiatric disorders and high societal costs associated with epielspy.

Longitudinal analysis of health care costs in patients with childhood onset inherited retinal dystrophies compared to healthy controls.

BACKGROUND: We evaluated health care costs in patients with childhood onset visual impairment caused by inherited retinal dystrophies (IRD). METHODS: The IRD cohort, identified from the Danish Registry of Blind and Partially Sighted Children, was compared to age- and sex-matched controls from the national, Danish population registry. Information on health care expenditures for somatic and psychiatric in- and outpatient services, purchase of prescription medications and paid assistance at home were obtained from national registries for the years 2002-2017. RESULTS: We included 412 in the IRD cohort (6,290 person years) and 1656 (25,088 person years) in the control cohort. Average, annual health care expenditures from age 0-48 years of age were €1,488 (SD 4,711) in the IRD cohort and €1,030 (4,639) in the control cohort. The largest difference was for out-patient eye care (13.26 times greater, 95% confidence interval 12.90-13.64). Psychiatric in-patient expenditures were 1.71 times greater (95% CI 1.66-1.76) in the IRD cohort but psychiatric out-patient health care costs were comparable between groups. CONCLUSIONS: Health care costs were approximately 40% greater in the IRD cohort compared to an age- and sex-matched sample from the general Danish population. This is relevant in the current situation with a number of trials aimed at treating IRDs using genetically based therapies. Although eye care expenditures were many times greater, they made up < 10% of the total health care expenditures even in the IRD cohort. The reduced costs related to injuries in the visually impaired cohort was a surprising finding but may reflect a reduced propensity to seek medical care rather than a reduced risk of injuries.

Direct and indirect costs of heart failure in relation to diabetes status - A nationwide study.

BACKGROUND AND AIM: Heart failure (HF) and diabetes mellitus (DM) are burdensome chronic diseases with high lifetime risks and numerous studies indicate associations between HF and DM. The objective of this study was to investigate the direct and indirect costs of HF patients with and without DM. METHODS AND RESULTS: Patients with a first-time diagnosis of HF from 1998 to 2016 were identified through nationwide Danish registries and stratified according to DM status into HF with or without DM. The economic healthcare cost analysis was based on both direct costs, including hospitalization, procedures, medication and indirect costs including social welfare and lost productivity. The economic burden was investigated prior to, at, and following diagnosis of HF. Patients with concomitant HF and DM were younger (median age 74 vs. 77), had more comorbidities and fewer were female as compared to patients with HF but without DM. The socioeconomic burden of concomitant HF and DM compared to HF alone was substantially higher; 45% in direct costs (€16,237 vs. €11,184), 35% in home care costs (€3123 vs. €2320), 8% in social transfer income (€17,257 vs. €15,994) and they had 27% lower income (€10,136 vs. €13,845). The economic burden peaked at year of diagnosis, but the difference became increasingly pronounced in the years following the HF diagnosis. CONCLUSION: Patients with concomitant HF and DM had a significantly higher economic burden compared to patients with HF but without DM.

Childhood-onset retinal dystrophies reduces life-time income by one third - an individual based socio-economic analysis.

BACKGROUND: The aim of this study was to evaluate lifetime income, educational level and workforce participation in patients with childhood-onset inherited retinal dystrophies (IRD). MATERIAL AND METHODS: The registry-based study using national, Danish databases on education, income, employment and social benefits in a cohort of 515 patients with childhood-onset IRD and without severe systemic comorbidities matched 1:4 to an age- and sex to a control sample of the Danish background population. Socio-economic status was modelled with focus on grade mark points after primary education, highest attained education at 30 years or age, employment and unemployment rate, disability pension and lifetime income. RESULTS: At 30 years of age, the proportion of those who had primary education as the highest achieved level was higher in the IRD group (35.4% versus 18.7%) and they were more likely to be receiving a disability pension (OR 11.77) or be unemployed (OR 6.63). Those at work had the same number of work hours as the control group, and the same proportion had obtained a Master or PhD degree (14%). At 30 years of age, income earnings were lower in the IRD group and the lifetime income was reduced by 30%. CONCLUSION: A few among those with childhood-onset IRD were able to obtain high educational levels, and many were assigned a disability pension from early adulthood or were unemployed, resulting in a markedly reduced lifetime income although grade mark points from primary education were comparable, suggesting that the difference was not explained by intellectual differences between the groups.

Burden of illness the first year after diagnosed bladder dysfunction among people with spinal cord injury or multiple sclerosis - a Danish register study.

BACKGROUND: People with spinal cord injury (SCI) or multiple sclerosis (MS) are often living with some degree of bladder and/or bowel dysfunction due to acquired neurogenic damage. The objective was to estimate the burden of illness of SCI and MS the first year after diagnosed bladder dysfunction. METHODS: Data were extracted from registers covering all Danish citizens. People with SCI or MS were indexed at diagnosis of bladder dysfunction. Inclusion period was 2002-2015 and cases and matched controls were followed for one year. RESULTS: A total of 2,132 subjects with SCI and 1,887 subjects with MS were identified. Healthcare utilization and societal costs per patient-year were significantly higher for cases compared to controls driven primarily by inpatient care. Cases with urinary tract infection had significantly higher inpatient costs per patient-year compared to controls (SCI: 544 EUR vs 23, p < 0.05; MS: 497 EUR vs 6, p< 0.05) and medication for constipation was significantly more costly per patient-year (SCI: 178 EUR vs 3, p < 0.05; MS: 78 vs 1, p < 0.05). CONCLUSIONS: The study demonstrates heavy societal and personal costs in the first year after bladder dysfunction in people with SCI or MS. This emphasizes the need for medical and social interventions to reduce the burden of illness.

The effects of pantoprazole vs. placebo on 1-year outcomes, resource use and employment status in ICU patients at risk for gastrointestinal bleeding: a secondary analysis of the SUP-ICU trial.

PURPOSE: Patients in intensive care units (ICUs) are at risk of stress-related gastrointestinal (GI) bleeding and stress ulcer prophylaxis (SUP), including proton pump inhibitors, is widely used in the attempt to prevent this. In this secondary analysis of Stress Ulcer Prophylaxis in Intensive Care Unit (SUP-ICU) trial, we assessed 1-year outcomes in the pantoprazole vs. placebo groups. METHODS: In the SUP-ICU trial, 3298 acutely admitted ICU patients at risk of GI bleeding were randomly allocated, stratified for site, to pantoprazole or placebo. In this secondary analysis, we assessed clinically important GI bleedings in ICU and 1-year mortality, health care resource use (e.g. readmission with GI bleeding, use of home care and general practitioner), health care costs, and employment status for the Danish participants using registry data. RESULTS: Among the 2099 Danish participants, 2092 had data in the registries; 1045 allocated to pantoprazole and 1047 to placebo. The number of clinically important GI bleedings in ICU was 1.9 percentage points [95% CI 0.3-3.5] lower in the pantoprazole group vs. the placebo group, but none of the 1-year outcomes differed statistically significantly between groups, including total health care costs (€1954 [- 2992 to 6899]), readmission with GI bleeding (- 0.005 admissions [- 0.016 to 0.005]), 1-year mortality (- 0.013 percentage points [- 0.051 to 0.026]), and employment (- 0.178 weeks [- 0.390 to 0.034]). CONCLUSION: Among ICU patients at risk of GI bleeding, pantoprazole reduced clinically important GI bleeding in ICU, but this did not translate into a reduction in 1-year mortality, health care resource use or improvements in employment status.

The impact of specialised treatment of low back pain on health care costs and productivity in a nationwide cohort.

BACKGROUND: Low back pain (LBP) is the most common diagnosis responsible for sick leave, long-term disability payments, and early retirements. Studies have suggested that the relatively small proportion of patients referred to a specialist for treatment, either conservative or surgical, accounts for most of the total costs of back pain. However, a complete and long-term picture of the socioeconomic burden associated with these two treatment regimens is lacking. METHODS: From a cohort encompassing the entire population in Denmark (5.8 million inhabitants), we identified patients with LBP referred to specialised treatment, either conservative or surgical, during 2007-2016. According to treatment modality, two different cohorts were constructed. Each patient was matched with ten background population controls based on age, sex, region of residency and time of treatment (month and year). Using extensive, nationwide register data, the healthcare costs and loss of productivity from two years before the first intervention until 2018 was investigated. FINDINGS: A total of 56,694 patients underwent surgical treatment, and 72,915 patients conservative treatment. Both cohorts had a significantly higher baseline cost two years before treatment compared with the background population controls. These measures increased sharply during the year after treatment. Five years after treatment, healthcare costs and loss of productivity remained proportionally similarly increased for the two treatment groups compared to the background population. Multiple surgeries had detrimental effects on long term productivity for the patients, and spouses to patients had marginally increased loss of productivity. INTERPRETATION: The results show that patients referred to specialised treatment of LBP display poor socioeconomic prognosis, regardless of conservative or surgical treatment modality. This development was reinforced in patients undergoing multiple surgeries and was also observed among spouses to the patients. Our findings of substantial loss of productivity across subgroups indicate that measures of successful treatment need to be more nuanced.

Ageing and health care expenditures: the importance of age per se, steepening of the individual-level expenditure curve, and the role of morbidity.

The demographic change towards a larger proportion of older individuals challenges universal health care systems in sustaining high-quality care and universal coverage without budget expansions. To build valuable predictions of the economic burden from population ageing, it is crucial to understand the determinants of individual-level health care expenditures. Often, the focus has been on the relative importance of an individual's age and time to death, while only a few newer studies highlight that individual-level health care expenditures are increasing faster for the elderly-i.e., creating a steepening of the individual-level health care expenditure curve over time. Applying individual-level administrative data for the entire Danish population, our study is the first to use a single data set to examine whether age, time to death, and a steepening of the individual-level health care expenditure curve all contributed to individual-level health care expenditures over a 12 year observation period (2006-2018). We find that individual-level expenditures are associated with an individual's age, an individual's time to death, and a steepening of the expenditure curve, with the steepening driven by individuals above age 75. We observe heterogeneity in the extent and age distribution of steepening across disease groups. The threefold combination of an ageing population, the correlation between expenditures and age per se, and a steepening of the expenditure curve make establishing financially sustainable universal health care systems increasingly difficult. To mitigate budgetary pressure, policy-makers should stimulate cost-effective medical advances and health care utilization in the treatment of elderly. Moreover, steepening scenarios should be added to future health care expenditure forecasts.

Welfare consequences of early-onset Borderline Personality Disorder: a nationwide register-based case-control study.

Information regarding welfare consequences of early onset of Borderline Personality Disorder (BPD) is limited. This nationwide study aimed to estimate the educational and employment outcome and health care costs of patients with early-onset BPD compared with matched controls. All patients (< 19 years) with first diagnosis of BPD in the Danish Patient Register (NPR) during the period 1983-2015 were included. Health care costs and socioeconomic variables were extracted from national registers. A total of 171 patients was compared with 677 controls. At the age of 20 years, BPD patients had reached a statistically significantly lower educational level (including lower primary school grades) and employment status compared with the controls. When adjusting for the parents' educational level, BPD patients were nearly 22 times more likely to be unemployed (OR = 21.7, 95% CI 11.9, 39.6), and nearly 15 times more likely to be on disability pension (OR = 14.8, 95% CI 5.0, 43.9) than controls. Furthermore, the total health care costs were more than 8 times higher in the BPD group. Early onset of BPD was associated with lower educational and vocational outcome and increased health care costs as early as at the age of 20 years. Even after controlling for parents' lower socioeconomic status, the patients have poorer outcome than the control group. This underlines that initiatives to support patients in finishing school and secondary education is highly needed. Future prevention and early intervention programs should target patients with early-onset BPD and their families.

Cost-effectiveness of an 8-week supervised education and exercise therapy programme for knee and hip osteoarthritis: a pre-post analysis of 16 255 patients participating in Good Life with osteoArthritis in Denmark (GLA:D).

OBJECTIVES: To evaluate 1-year cost-effectiveness of an 8-week supervised education and exercise programme delivered in primary care to patients with symptomatic knee or hip osteoarthritis (OA). DESIGN: A registry-based pre-post study linking patient-level data from the Good Life with osteoArthritis in Denmark (GLA:D) registry to national registries in Denmark. SETTING AND PARTICIPANTS: 16 255 patients with symptomatic knee or hip OA attending GLA:D. INTERVENTION: GLA:D is a structured supervised patient education and exercise programme delivered by certified physiotherapists and implemented in Denmark. OUTCOME MEASURES: Adjusted healthcare costs per Quality-Adjusted Life Year (QALY) gained from baseline to 1 year (ratio of change in healthcare costs to change in EuroQoL 5-Dimensions 5-Level questionnaire (EQ-5D)). All adjusted measures were estimated using a generalised estimating equation gamma regression model for repeated measures. Missing data on EQ-5D were imputed with Multiple Imputations (3 months: 23%; 1 year: 39 %). RESULTS: Adjusted change in healthcare cost was 298€ (95% CI: 206 to 419) and 640€ (95% CI: 400 to 1009) and change in EQ-5D was 0.035 (95% CI: 0.033 to 0.037) and 0.028 (95% CI: 0.025 to 0.032) for knee and hip patients, respectively. Hence estimated adjusted healthcare costs per QALY gained was 8497€ (95% CI: 6242 to 11 324) for knee and 22 568€ (95% CI: 16 000 to 31 531) for hip patients. In patients with high compliance, the adjusted healthcare costs per QALY gained was 5438€ (95% CI: 2758 to 9231) for knee and 17 330€ (95% CI: 10 041 to 29 364) for hip patients. Healthcare costs per QALY were below conventional thresholds for willingness-to-pay at 22 804€ (20 000£) and 43 979€ (US$50 000), except the upper limit of the 95% CI for hip patients which was in between the two thresholds. CONCLUSIONS: A structured 8-week supervised education and exercise programme delivered in primary care was cost-effective at 1 year in patients with knee or hip OA supporting large-scale implementation in clinical practice.

Disentangling treatment pathways for knee osteoarthritis: a study protocol for the TREATright study including a prospective cohort study, a qualitative study and a cost-effectiveness study.

INTRODUCTION: Knee osteoarthritis (OA) is associated with chronic knee pain and functional disability that negatively affect the ability to carry out normal daily activities. Patients are offered a large variety of non-surgical treatments, often not in accordance with clinical guidelines. This observational study will provide a comprehensive overview of treatment pathways for knee OA during the first 2 years after consulting an orthopaedic surgeon, including timing and order of treatment modalities, predictors of treatment outcomes, cost-effectiveness of treatment pathways and patients' views on different treatment pathways. METHODS AND ANALYSIS: Patients with primary referrals to an orthopaedic surgeon due to knee OA are consecutively invited to participate and fill out a questionnaire prior to their consultation with an orthopaedic surgeon. Follow-up questionnaires will be obtained at 6 and 24 months after inclusion. Based on a prospective cohort study design, including questionnaires and register data, we will (1) describe treatment pathways for knee OA during the first 2 years after consulting an orthopaedic surgeon; (2) describe the characteristics of patients choosing different treatment pathways; (3) develop predictive models for patient-self-determined classifications of good and poor treatment outcomes; (4) evaluate the cost-effectiveness of treatment pathways that live up to clinical guidelines versus pathways that do not; based on a qualitative study design using semistructured individual interviews, we will (5) describe the patients' perspectives on treatment pathways for knee OA. ETHICS AND DISSEMINATION: The study is approved by the Danish regional ethical committee (journal number H-17017295) and the Danish Data Protection Agency (journal number AHH-2017-072). Data will be anonymised and handled in line with the General Data Protection Regulation and the Danish Data Protection Act. The study results will be submitted to international open-access peer-reviewed journals and disseminated at conferences. TRIAL REGISTRATION NUMBER: NCT03746184, pre-results.

Attributable societal costs of first-incident obesity-related cardiovascular comorbidities in Denmark.

Background: Obesity is associated with increased societal costs, primarily due to its comorbidities. The objective of this study was to estimate the 3-year attributable societal costs of the first event of cardiovascular comorbidities among people with obesity.Methods: We used an incidence-based cohort study based on Danish national registries. Attributable costs of each event were calculated as the difference between costs of individuals with an event and costs incurred by matched controls.Results: We identified 58,597 individuals with a diagnosis of obesity. On average, 2,038 individuals were diagnosed annually with one or more than ten cardiovascular comorbidities between 2007 and 2013. The 3-year attributable societal costs (health-care costs plus productivity loss) for patients of working age ranged from 8,164 EUR for other ischemic heart disease to 32,203 EUR for hemorrhagic stroke. In the incidence year, costs were mainly driven by health-care costs, while productivity loss and income transfer payments were the primary drivers in subsequent years.Conclusion: The onset of obesity-related cardiovascular comorbidities affected health-care costs and work ability to an extent where sick pay and disability pension were required. Our study demonstrates the need to intensify obesity and cardiovascular disease risk factor management to prevent costly and debilitating obesity-related comorbidities.

The impact of changed treatment patterns in multiple myeloma on health-care utilisation and costs, myeloma complications, and survival: A population-based comparison between two time periods in Denmark.

OBJECTIVES: To evaluate health-care utilisation and costs, myeloma complications and survival in Danish patients with multiple myeloma (MM) before and after implementation of new early-line treatments in 2009. METHODS: Based on data from the Danish National Health Registers, 3518 patients diagnosed with MM during 2002-2005 or 2010-2013 and randomly matched control individuals were identified, and health-care utilisation and costs were estimated. RESULTS: Health-care utilisation showed a marked shift from inpatient admissions towards outpatient visits. From early to late period, the mean annual number of outpatient visits increased by 22% and 28% in patients <65 years and ≥65 years, respectively. Additionally, the mean annual outpatient service costs increased correspondingly from 17 001€ to 23 643€ in younger patients and from 11 317€ to 16 144€ in the elderly. Increasing outpatient costs were outbalanced by lower inpatient admission costs and the adjusted total mean annual costs decreased in younger patients, probably partly due to fewer myeloma complications. The five-year survival rates increased markedly in both younger (HR = 0.51) and elderly (HR = 0.69) patients. CONCLUSION: Despite the introduction of new expensive early-line MM treatments in 2009, health-care costs remained stable due to a shift in health-care utilisation towards outpatient clinic care and fewer complications.

Costs of schizotypal disorder: A matched-controlled nationwide register-based study of patients and spouses.

OBJECTIVE: Information on societal cost of patients with schizotypal disorder is limited. The aim was to investigate the societal costs of schizotypal disorder before and after initial diagnosis including both patients and their spouses. METHODS: A register-based cohort study of 762 patients with incident schizotypal disorder (ICD-10; F21) including their spouses and 3048 matched controls, during 2002 to 2016. Total healthcare costs, home care costs, and costs of lost productivity of patients and spouses were included in the analysis. RESULTS: Total costs amounted €47,215 per year for patients with schizotypal disorder, which was fifteen times higher than the matched controls. Of these, 41% were healthcare and home care costs and 59% were costs of lost productivity. Healthcare costs and costs of lost productivity were increased during five years before initial diagnosis of schizotypal disorder. Total costs of spouses to patients were €21,384 compared with € 2519 among spouses of controls. 75% of the total costs of spouses to patients were related to lost productivity. The total costs were higher than the costs of borderline personality disorder, but on the same level as the costs of schizophrenia identified in earlier comparable studies. CONCLUSIONS: The total societal costs of patients with schizotypal disorder drawn from national registers differed substantially from the controls representing the general population. As evidence-based recommendations for diagnoses and treatment of patients with schizotypal disorder do not exist, future research should focus on developing effective treatment for this group of patients to reduce cost of illness.
