Background: The estimations of the economic burden of glaucoma have focused on comparing different treatment modalities; hence, the total direct and indirect costs of glaucoma at population level are not well known., Objective: To estimate the direct and indirect costs of glaucoma and its treatment in Finland., Methods: Economic and glaucoma data were collected from the cross-sectional nationwide Health 2000 health examination survey linked to multiple national registers, which allowed a 13-year follow-up between 1999-2011 among survey participants. Direct costs covered eye- and non-eye-related hospitalizations and outpatient visits, outpatient health care services, and travel costs among participants aged 30 years or older, adjusted for age and sex. Indirect costs covered premature retirement and productivity losses among participants aged 30-64 years. Glaucoma patients (n = 192) were compared with non-glaucomatous population (n = 6,952)., Results: The annual additional total direct costs were EUR 2,660/glaucoma patient, EUR 1,769/glaucoma patient with medication, and EUR 3,979/operated glaucoma patient compared with persons without glaucoma. The respective additional total indirect costs were EUR 4,288, EUR 3,246, and EUR 12,902 per year. In total, the additional annual direct and indirect expenditures associated with glaucoma in Finland were EUR 202 million (0.86% of total expenditures of health care) and EUR 71 million (0.03% of the Finnish gross domestic product) arising mainly from non-eye-related hospitalizations and productivity losses, respectively., Conclusion: Glaucoma is associated with an increased health care consumption mainly due to non-eye-related health care, which can be explained by the vision loss as well as increased number of co-morbidities among glaucoma patients. Therefore, glaucoma constitutes a major economic burden for the health care system and society, highlighting the importance of early glaucoma interventions. The difference in direct and indirect costs between glaucoma treatment groups is explained by the uneven distribution of co-morbidities., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2023 Purola et al.

Effective density (ρ eff ) is an important property describing particle transportation in the atmosphere and in the human respiratory tract. In this study, the particle size dependency of ρ eff was determined for fresh and photochemically aged particles from residential combustion of wood logs and brown coal, as well as from an aerosol standard (CAST) burner. ρ eff increased considerably due to photochemical aging, especially for soot agglomerates larger than 100 nm in mobility diameter. The increase depends on the presence of condensable vapors and agglomerate size and can be explained by collapsing of chain-like agglomerates and filling of their voids and formation of secondary coating. The measured and modeled particle optical properties suggest that while light absorption, scattering, and the single-scattering albedo of soot particle increase during photochemical processing, their radiative forcing remains positive until the amount of nonabsorbing coating exceeds approximately 90% of the particle mass.

Introduction: Currently, 15-20% of individuals with coronary artery disease (chronic coronary syndrome [CCS]) or peripheral artery disease (PAD) receiving routine treatment experience cardiovascular events (CVEs) within 3-4 years. Using PICOSTEPS (Patients-Intervention-Comparators-Outcomes-Setting-Time-Effects-Perspective-Sensitivity analysis) reporting, we evaluated the cost-effectiveness of recently approved rivaroxaban 2.5 mg twice daily in combination with acetylsalicylic acid 100 mg daily (RIV + ASA) for the prevention of CVEs among Finns with CCS or symptomatic PAD., Methods: Myocardial infarction, ischemic stroke, intracranial hemorrhage, acute limb ischemia, amputations, major extracranial bleeding, venous thromboembolism, and cardiovascular deaths were modeled in a Markov model examining a cohort of patients with CCS or symptomatic PAD. Relative effects of the intervention (RIV + ASA) and comparator (ASA) were based on the COMPASS trial. The primary outcome was 3%/year discounted incremental cost-effectiveness ratio (ICER), defined as cost (2019 euros) per quality-adjusted life year (QALY) gained in the Finnish setting over a lifetime horizon. In addition to nonfatal and fatal CVEs, the effects factored Finnish non-CVE mortality, quality of life, and direct costs from a public payer perspective. Disaggregated costs and QALYs, costs per life year gained (LYG), and ischemic strokes avoided, net monetary benefit (NMB), expected value of perfect information (EVPI), economic value-added (EVA), cost-effectiveness table, and acceptability frontier were examined. Probabilistic and deterministic sensitivity analyses were conducted., Results: In the deterministic comparison with ASA over a lifetime horizon, RIV + ASA resulted in a benefit of 0.404 QALYs and 0.474 LYGs for an additional cost of €3241, resulting in an ICER of €8031/QALY. The probabilistic ICER was €4313/QALY (EVPI €1829/patient). RIV + ASA had positive NMB (€8791/patient), low EVPI (€88/patient), high EVA (€8703/patient), and 91% probability of cost-effectiveness using the willingness-to-pay of €25,254/QALY. The primary result was conservative and robust for RIV + ASA., Conclusion: RIV + ASA was a cost-effective treatment alternative compared with ASA in patients with CCS or symptomatic PAD in Finland.

Introduction: There is an unmet need for well-tolerated antiepileptic drugs (AEDs) that effectively control focal onset seizures. This study aimed to evaluate the economic value of new AEDs in the treatment of focal onset seizure, with or without secondary generalization, in Finnish adults and adolescents with epilepsy, comparing brivaracetam with perampanel as adjunctive AEDs., Methods: Economic value was assessed using cost-utility analysis. Periods of AED initiation, titration, response assessment (seizure freedom, ≥ 50% reduction, no response), switching in no response or treatment-emergent adverse events (TEAEs), and death were simulated using a discrete-event simulation model. Responses and switching were simulated based on a comprehensive Bayesian network meta-analysis. The primary modeled outcome was the 3%/year discounted incremental cost-effectiveness ratio (ICER). Discounted quality-adjusted life-years (QALYs), payer costs (year 2017 Euro) per patient, and net monetary benefit (NMB) were secondary outcomes. Probabilistic and comprehensive deterministic sensitivity analyses were conducted., Results: Brivaracetam was more efficacious and had fewer TEAEs than perampanel and other AEDs. Modeled average 5-year QALYs and costs were 3.671 and €28,297 for brivaracetam and 3.611 and €27,979 for perampanel, respectively. The resulting ICER for brivaracetam versus perampanel was only €5345/QALY gained in a deterministic base case scenario. Brivaracetam had a positive NMB and high probability of cost-effectiveness of €1190 and 71% or €1944 and 80% with the assumed willingness to pay of €25,358 or €38,036/QALY gained, respectively. The primary result was robust, with a positive NMB persistent in all sensitivity analysis scenarios. When switching from brivaracetam to perampanel was excluded from the modeling or switching from perampanel to brivaracetam was included, brivaracetam was cost-saving and more effective than perampanel (dominant)., Conclusion: These simulated comparisons demonstrated that brivaracetam was more effective and potentially also more affordable than perampanel. Thus, brivaracetam is likely a cost-effective and net beneficial alternative to perampanel for treatment of focal onset seizures. Plain language summary available for this article.

Purpose: The impact of visual acuity (VA) on Health-Related Quality of Life (HRQoL) and the cross-sectional and longitudinal differences in HRQoL during the 11-year follow-up were investigated. The aim was to examine the impact declining vision has on HRQoL and to provide comparable data to facilitate the allocation of health-care resources., Methods: We utilized nationwide health examination surveys carried out by the National Institute for Health and Welfare in 2000 and 2011, providing a representative sampling of the Finnish adult population aged 30 and older. VA was assessed through Snellen E test, and HRQoL scores were evaluated using EQ-5D and 15D questionnaires. Multiple imputations with Markov chain Monte Carlo method was used to utilize the data more effectively. Regression analyses were conducted to assess the impact of declining VA on HRQoL, adjusted for incident comorbidities., Results: Lower VA status was associated with significantly lower HRQoL at both time points, most clearly observable below the VA level of 0.5. Declining VA resulted in statistically significant decline in HRQoL during the follow-up, greater with distance than near VA. 15D impairment associated with decline in the distance VA was also clinically meaningful and greater than that associated with any of the examined comorbidities., Conclusions: HRQoL was significantly and meaningfully impaired even before the threshold of severe vision loss or blindness was reached. The results encourage the improvement of available treatment options aiming to postpone the onset of visual impairment or declining VA, to maintain better quality of life among the population.

Objective: To examine the association between neuropsychiatric symptoms (NPS) with self- and caregiver-rated Quality of Life (QoL) for patients with Alzheimer's disease (AD) during a 5-year follow-up., Methods: The ALSOVA 5-year follow-up study included, at baseline, 236 patients with either very mild (Clinical Dementia Rating Scale (CDR) 0.5), or mild (CDR 1) AD, together with their caregivers from three Finnish hospital districts. QoL was evaluated using patient self-reported, and caregiver-rated, QoL in AD (QoL-AD) scores. NPS were assessed using the Neuropsychiatric Inventory (NPI), and AD severity was evaluated using the CDR, with cognition tested by the mini-mental state examination. The performance of daily activities was assessed using the Alzheimer's Disease Cooperative Study-Activities of Daily Living Inventory., Results: Over the 5-year follow-up period, patient self-reported QoL-AD scores did not change significantly (p = 0.245), despite increases in their NPS. However, caregiver-rated patient QoL-AD scores declined significantly (p ≤ 0.001), as total NPI scores increased during follow-up. No NPS at baseline, and only apathy at follow-up, correlated significantly (p = 0.007) with patient self-rated QoL-AD scores. Caregiver-rated patient QoL-AD scores correlated significantly with most NPS, especially (p ≤ 0.001) apathy, agitation, anxiety, irritability, depression, and delusions at baseline, and delusions, hallucinations, apathy, appetite disturbances, and anxiety during follow-up., Conclusions: Patient rated QoL-AD scores are an unreliable tool with which to evaluate the success of therapy for NPS. Instead, caregiver-rated scores for patients correlated well with NPI scores, and health care professionals in the clinic should preferentially use these.

Aims: Treatment of iron deficiency (ID) in patients with heart failure (HF) with intravenous iron substitution [ferric carboxymaltose (FCM)] has previously shown significant improvements in exercise capacity, New York Heart Association (NYHA) functional class, quality of life, and reduction of hospitalization. The aim of this study was to estimate the budget impact of FCM treatment for patients with HF and ID., Methods and Results: Individual patient data from four double-blind randomized controlled trials were pooled for this analysis. Expected outcomes were modelled for a treatment period of 1 year, using multivariate statistical methods. Associated unit costs were derived from claims data. Budget impact was calculated from the perspective of the Statutory Health Insurance. Multiple deterministic sensitivity analyses were performed. The annual budget impact for therapy with FCM vs. no-iron therapy was €2 735 505 and €2 695 474 for 1000 patients, respectively, resulting in additional annual costs of €40.03 for each treated patient. Main costs drivers are the FCM treatment cost and cost of hospitalizations due to HF worsening. FCM therapy compared with no-iron therapy resulted in reduced cost per 1000 patients: for reduced hospitalization due to HF worsening (52 vs. 129 hospitalizations amounting to €230 591 vs. €597 078), for reduced other medication (€1 611 007 vs. €1 679 908), fewer outpatient visits (€332 523 vs. €378 019), and home visits (€29 627 vs. €40 469). Sensitivity analyses showed robustness of the results., Conclusions: Therapy with FCM has a minimal budget impact of €40 031 per 1000 patients per year. This budget impact translates into reduced and shorter hospitalizations and improved symptomatic status of the patients., (© 2017 The Authors.

Purpose: To examine caregivers' health-related quality of life (HRQoL) and well-being during the first 3 years after their family member's Alzheimer's disease (AD) diagnosis and assessed the relationship between caregivers' HRQoL, well-being, and the severity of AD. Further, to compare of caregivers' HRQoL to general population., Methods: Longitudinal design (36 months) after AD diagnosis of 236 caregiver-patient dyads. Linear regression was used to assess age- and gender-adjusted association between repeated measurements of caregivers' HRQoL and the severity of AD. For comparison with general population, the National Health 2011 Health Examination Survey data was utilized., Results: Caregivers had significantly lower HRQoL than age- and gender-standardized counterparts. Severity of AD was significantly (p < 0.05) associated with the mobility and depression dimensions of caregiver's HRQoL but not with the total HRQoL index score., Conclusions: Caregivers' HRQoL seems to deteriorate earlier than previously noted. The severity of AD has not that great impact on caregiver's HRQoL as assumed.

Objectives: Present study examines the relationship between the estimated risk of developing type 2 diabetes (T2D) and health-related quality of life (HRQoL). We quantify the association between Finnish Diabetes Risk Score (FINDRISC) and HRQoL, and examine the potential use of FINDRISC as tool to evaluate HRQoL indirectly., Methods: We conducted a cross-sectional study comprising 707 Finnish people without a diagnosis of T2D between the ages of 51 and 75 years. The risk of developing T2D was assessed using the validated and widely used FINDRISC (range 0-26 points), and quality of life was measured using two preference-based HRQoL instruments (15D and SF-6D) and one health profile instrument (SF-36). Effects of the individual FINDRISC items and demographic and clinical characteristics, such as co-morbidities, on HRQoL were studied using multivariable Tobit regression models., Results: Low HRQoL was significantly and directly associated with the estimated risk of developing T2D. An approximate 4-5 point change in FINDRISC score was observed to be associated with clinically noticeable changes in the preference-based instrument HRQoL index scores. The association between HRQoL and the risk of developing T2D was also observed for most dimensions of HRQoL in all applied HRQoL instruments. Overall, old age, lack of physical activity, obesity, and history of high blood glucose were the FINDRISC factors most prominently associated with lower HRQoL., Conclusions: The findings may help the health care professionals to substantiate the possible improvement in glucose metabolism and HRQoL potentially achieved by lifestyle changes, and better convince people at high risk of T2D to take action towards healthier lifestyle habits. FINDRISC may also provide an accurate proxy for HRQoL, and thus by estimating the risk of T2D with the FINDRISC, information about patients' HRQoL may also be obtained indirectly, when it is not feasible to use HRQoL instruments.

Objective: To examine and compare self-rated and caregiver-rated measures of quality of life (QoL) in relation to disease progression in patients with very mild or mild Alzheimer disease (AD) and at what disease stage patient's ability to respond to QoL questionnaires with or without assistance begins to diminish., Methods: 236 patients with very mild or mild AD and their family caregivers from three Finnish hospital districts participated in this prospective, longitudinal study with 5 years of follow-up. Three patient-reported instruments were used to assess QoL (the generic 15D, the Quality of Life in Alzheimer Disease [QoL-AD] questionnaire, and a visual analogue scale) as well as one caregiver-rated assessment of patient QoL (QoL-AD). AD severity was evaluated with the Clinical Dementia Rating Scale - Sum of Boxes (CDR-SOB)., Results: All self- and caregiver-rated QoL estimates correlated with AD severity. The self- and caregiver-rated QoL scores began to diverge even with very mild cognitive impairment after CDR-SOB reached 4, the value that corresponds with a Mini-Mental State Examination (MMSE) score of 25-30. Patients also began to need assistance in responding to questionnaires at very early stages of AD (CDR-SOB score: 4-6). Furthermore, their ability to respond to QoL questionnaires with or without assistance declined after CDR-SOB reached 11 points, a value that correlates with an early moderate stage of AD and MMSE score of 11-20., Conclusions: AD patients' self-rated QoL ratings are much more insensitive to disease progression than caregiver ratings., (Copyright © 2015 American Association for Geriatric Psychiatry.

Neuropsychiatric symptoms of Alzheimer's disease (AD) such as depression may be associated with pain, which according to the literature may be inadequately recognized and managed in this population. This study aimed to identify the factors associated with analgesic use in persons with AD; in particular, how AD severity, functional status, neuropsychiatric symptoms of AD, co-morbidities and somatic symptoms are associated with analgesic use. 236 community-dwelling persons with very mild or mild AD at baseline, and their caregivers, were interviewed over five years as part of the prospective ALSOVA study. Generalized Estimating Equations (GEEs) were used to estimate unadjusted and adjusted odds ratios (ORs) for the factors associated with analgesic use over a five year follow-up. The proportion of persons with AD using any analgesic was low (13.6%) at baseline and remained relatively constant during the follow-up (15.3% at Year 5). Over time, the most prevalent analgesic changed from non-steroidal anti-inflammatories (8.1% of persons with AD at Year 1) to acetaminophen (11.1% at Year 5). Depressive symptoms (measured by the Beck Depression Inventory, BDI) were independently associated with analgesic use, after effects of age, gender, education, AD severity, comorbidities and somatic symptoms were taken into account. For every one unit increase in BDI, the odds of analgesic use increased by 4% (OR = 1.04, 95% confidence interval CI = 1.02-1.07). Caregiver depressive symptoms were not statistically significantly associated with analgesic use of the person with AD. Depressive symptoms were significantly associated with analgesic use during the five year follow-up period. Possible explanations warranting investigation are that persons with AD may express depressive symptoms as painful somatic complaints, or untreated pain may cause depressive symptoms. Greater awareness of the association between depressive symptoms and analgesic use may lead to safer and more effective prescribing for these conditions.

Background/aims: Measuring and predicting Alzheimer's disease (AD) progression is important in order to adjust treatment and allocate care resources. We aimed to identify a combination of subtests from the Consortium to Establish a Registry for Alzheimer's Disease Neuropsychological Battery (CERAD-NB) that best correlated with AD progression in follow-up as well as to predict AD progression., Method: A total of 236 participants with very mild [Clinical Dementia Rating (CDR) = 0.5] or mild AD (CDR = 1.0) at baseline were followed up for 3 years. The CERAD-NB and Mini-Mental State Examination (MMSE) were used to assess cognition, and the CDR scale sum of boxes (CDR-sb) was employed to evaluate AD progression. Generalized estimating equations were used to develop models to predict and follow up disease progression., Results: Performance declined on all CERAD-NB subtests. The ability of the separate subtests to distinguish between groups (baseline CDR = 0.5 or 1.0) diminished during follow-up. The best combination of subtests that explained 62% of CDR-sb variance in follow-up included verbal fluency, constructional praxis, the clock drawing test, and the MMSE. Baseline values of the same combination predicted 37% of the CDR-sb change., Conclusion: A short version of the CERAD-NB subtests provides a promising and time-efficient alternative for measuring cognitive deterioration during AD follow-up. Although the initial signs of AD include memory difficulties, it may be useful to assess non-memory tasks in follow-up.

Purpose: To examine the general health status and health-related quality of life (HRQOL) along the diabetes continuum of middle-aged and older Finns, and to determine the glucose metabolism stage by which the HRQOL has decreased noticeably., Methods: The cross-sectional sample consisted of 920 persons aged 51-75 from the general population in a single municipality in a rural area of Eastern Finland. Data were adjusted for age, sex, smoking history, current alcohol consumption, employment and marital status. The HRQOL and health status were evaluated using two preference-based HRQOL instruments, 15D and SF-6D, and one health profile instrument, 36-Item Short Form Health Survey (SF-36)., Results: Individuals with impaired glucose tolerance (IGT) and type 2 diabetes had noticeably low mean SF-6D, 15D and general health status. The decrease in overall HRQOL was mainly due to a decline in the physical dimensions of HRQOL. The adjusted odds ratios (95% CI) for having noticeably low HRQOL on SF-6D, 15D and general health dimension of SF-36 associated with IGT were 1.95 (1.18-3.25), 1.35 (0.84-2.18) and 2.00 (1.21-3.29), respectively., Conclusions: The progression along the diabetes continuum was significantly associated with a decrease in HRQOL and health status. Furthermore, the data indicate that when a person is detected to have IGT, the HRQOL and general health status have already diminished noticeably. The prevailing evidence suggests that detection and intervention before a patient develops IGT is essential in order to minimize the loss of quality of life and quality-adjusted life years.

Purpose: The aim of the study is to examine the health-related quality-of-life (HRQOL) impact of the nocturnal awakenings and the duration of the sleep in the Finnish middle-aged and older population., Methods: Cross-sectional sample consisted of 823 community-dwelling persons aged 55-75 living in a single municipality in a rural area of Eastern Finland. Frequency of the nocturnal awakenings was dichotomized as reporting "frequent," if the participant reported subjectively awakening "often" or "very often," and "infrequent" if the participant reported awakening "sometimes" or less frequently. HRQOL was measured with a preference-based HRQOL-index instrument, 15D. Analyses were adjusted for gender, BMI, morbidities, depression, employment and marital status, current smoking and drinking, exercise, recommendation to exercise from a health care professional, and subjective opinion about own exercise habits., Results: Frequent nocturnal awakenings had statistically and clinically significant negative impact on HRQOL, the mean (SE) adjusted marginal HRQOL impact being -0.0416 (0.006). More than 10 and less than 6.5 h of daily sleep were associated with higher probability of having low HRQOL, adjusted odd ratios (95 % CI) being 2.65 (1.11-6.33) and 2.65 (1.55-4.52), respectively. However, the changes in daily sleep duration did not have noticeable influence on the significance or magnitude of the negative HRQOL impact of the frequent nocturnal awakenings., Conclusions: Nocturnal awakenings displayed a strong independent association with decreased HRQOL. The findings suggest that both clinicians and researchers should pay closer attention to nocturnal awakenings and other sleep problems in order to find ways to improve the quality of life in individuals with such conditions.
