Multiplicative, additive, and interactive associations of 25-hydroxyvitamin D with lung and prostate cancer.

Results regarding the epidemiological association of vitamin D with lung (LCA) and prostate cancer (PCA) are controversial. This study tested whether serum 25-hydroxyvitamin D [25(OH)D] concentrations have interactive epidemiological associations with smoking, the number-one risk factor for LCA, and age, the number-one risk factor for PCA. Also, this study investigated whether the associations of 25(OH)D, smoking, age, alcohol consumption, body mass index, diet (the healthy Nordic diet score), and physical activity with incident LCA and PCA are multiplicative or additive. The study of association types makes it easier to select appropriate statistical methods. The Kuopio Ischaemic Heart Disease Risk Factor Study provided the data of 2578 men with 112 LCA and 300 PCA cases over 35 years by the end of 2019. Serum 25(OH)D did not associate with LCA and PCA or interact with smoking and age. The association of smoking with LCA was additive; 13 extra cases per 1000 men every 10 years. Age and alcohol consumption multiplicatively increased the hazard of LCA (hazard ratio, 95% confidence interval for age >50: 3.56, 1.82-6.17; drink per week: 1.01, 1.00-1.03), whereas adherence to healthy Nordic diet decreased it (per score point: 0.95, 0.89-1.00). The association of age >50 with PCA was additive; 2.5 extra cases per 1000 men every 10 years. To conclude, there was no epidemiological relationship of pre-diagnostic 25(OH)D concentrations with the incidence of LCA and PCA. The respective associations of smoking and age >50 with LCA and PCA were additive rather than multiplicative.

How competing risks affect the epidemiological relationship between vitamin D and prostate cancer incidence? A population-based study.

We hypothesized that controversial results regarding the epidemiological relationship between circulating 25-hydroxyvitamin D, 25(OH)D, and risk of prostate cancer (PCA) incidence are partly due to competing risks. To test the hypothesis, we studied associations across 25(OH)D, PCA and death in 2578 middle-aged men belonging to the Kuopio Ischaemic Heart Disease Risk Factor Study. The men were free of cancer at baseline, and the mean (SD) follow-up time was 23.3 (9.1) years. During this period, 296 men had a PCA diagnosis, and 1448 men died without the PCA diagnosis. The absolute risk of developing PCA was highest in the highest 25(OH)D tertile (15%), whereas that of death was highest in the lowest 25(OH)D tertile (67%). A competing risk analysis showed that belonging to the highest 25(OH)D tertile increased the risk of PCA incidence and improved survival with the respective hazard ratios (HR) of 1.35 (95% CI = 1.07-1.70) and 0.79 (95% CI = 0.71-0.89). Adjusting for 10 covariates together with 25(OH)D did not significantly change the results, but the respective adjusted HRs for PCA and death were 1.20 and 0.87. To conclude, the competing risk analysis did not eliminate the direct relationship between 25(OH)D and PCA but rather strengthened it.

Improving the value of healthcare systems using the Triple Aim framework: A systematic literature review.

The notion of value-based healthcare has become increasingly important for healthcare institutions, and more and more countries are adopting its representative approach-namely, the US Institute for Healthcare Improvement's Triple Aim framework for optimizing health system performance in terms of population health, patient experience, and cost of care. In this study, using a five-step systematic review protocol and PRISMA methods we systematically review and analyze with descriptive and qualitative analysis methods literature on the results of using the Triple Aim framework for assessment at the health system level, especially the concept of balance among the framework's goals. Inclusion criteria were that the paper evaluated the policy-level impact of value-based healthcare movements based on the Triple Aim goals, discussing at least one of the goals or the balance. Our analysis shows a lack of consensus on the impact of each goal and on the concept of a balance between the goals, and a paucity of literature related to the pursuit of the Triple Aim at the health system level. To properly evaluate the impact of the value-based healthcare movement, a standard set of measures aligned with the context is needed. The results of this study are expected to contribute to the improved assessment of health system performance, development of the Triple Aim framework's measures, and ultimately, enhanced effectiveness in achieving healthcare goals.

Value-based healthcare logics and their implications for Nordic health policies.

Value-based healthcare (VBHC) is a widely approved logic for financing services, using innovative care models and evaluating healthcare outcomes. It is consistent with the Triple Aim framework of simultaneously improving population health, patient experience and the costs of care. In Nordic countries, VBHC has been mainly implemented as a strategic concept in developing hospitals. Despite the evident interest in VBHC as a management trend in healthcare organisations, the studies concerning the implications of VBHC logics on health policies have been scant. This study aimed to fill this gap by building a conceptual bridge between national health policy and value-based care. Through the Triple Aim framework, we explored how VBHC goals have evolved in Finnish Government Programmes from 1995 to 2015 by using qualitative document analysis and interviews. The study addresses the evolution and national impacts of VBHC. Our results show that the goals of Triple Aim gradually become evident at the Finnish health policies. All three Triple Aim goals were present, though the equal prioritisation of these goals only emerged in 2015, also highlighting patient experience. We argue that VBHC logics have indeed affected Nordic welfare policies, not only at the organisational level but also concerning performance measurement and care delivery. This may imply that the diffusion of VBHC logics evolves from healthcare organisations to policymaking instead of top-down. Particularly in publicly financed systems, VBHC indicates a transformation to a new public governance ideology, accelerating policy goals that promote customer responsiveness and value creation for citizens.

Nursing intensity scores did not correlate well with reimbursement claims for infant bronchiolitis.

AIM: We retrospectively evaluated the hospital reimbursement rates for inpatient bronchiolitis treatment and then compared them to the RAFAELA® nursing intensity scores. METHODS: We selected all 44 bronchiolitis patients treated in the paediatric intensive care unit (PICU) and then for each PICU-treated patient two patients treated on the ward (n = 88) under 12 months of age in 2010-2015. The data included medical histories, hospital reimbursement rates using the Nordic Diagnosis Related Groups (NordDRG) or expense categories and the RAFAELA® scores. RESULTS: Reimbursement claims were mostly based on expense categories for PICU admissions and NordDRG categories for ward admissions. The median (range) was €6352 (€1330-30 554) and €2009 (€768-6027) per episode for the PICU and ward cases, respectively. The median lengths of hospital stay were 8.5 days (3-18) and 3 days (1-8), respectively. Higher RAFAELA® scores were associated with nasal continuous positive airway pressure therapy and mechanical ventilation in the PICU and oxygen supplementation and nasogastric tube feeding on the ward. The correlation coefficients between RAFAELA® scores and hospital reimbursement claims ranged from 0.121-0.450. CONCLUSION: Hospital reimbursement claim for a PICU admission was three times as much as a ward admission and reimbursement claims for bronchiolitis did not match with nursing intensity scores.

Dietary proteins and protein sources and risk of death: the Kuopio Ischaemic Heart Disease Risk Factor Study.

BACKGROUND: Previous studies investigating protein intake in relation to mortality have provided conflicting results. OBJECTIVE: We investigated the associations of dietary protein and protein sources with risk of disease death in the prospective, population-based Kuopio Ischaemic Heart Disease Risk Factor Study. METHODS: The study population consisted of 2641 Finnish men, aged 42-60 y at baseline in 1984-1989. We estimated protein intakes with 4-d dietary records at baseline and collected data on disease deaths from the national Causes of Death Register. Cox proportional hazards regression models were used to estimate HRs and 95% CIs. RESULTS: During the average follow-up of 22.3 y, we observed 1225 deaths due to disease. Higher intakes of total protein and animal protein had borderline statistically significant associations with increased mortality risk: multivariable-adjusted HR (95% CI) in the highest compared with the lowest quartile for total protein intake = 1.17 (0.99, 1.39; P-trend across quartiles = 0.07) and for animal protein intake = 1.13 (0.95, 1.35; P-trend = 0.04). Higher animal-to-plant protein ratio (extreme-quartile HR = 1.23; 95% CI: 1.02, 1.49; P-trend = 0.01) and higher meat intake (extreme-quartile HR = 1.23; 95% CI: 1.04, 1.47; P-trend = 0.01) were associated with increased mortality. When evaluated based on disease history at baseline, the association of total protein with mortality appeared more evident among those with a history of type 2 diabetes, cardiovascular disease, or cancer (n = 1094) compared with those without disease history (n = 1547) (P-interaction = 0.05 or 0.07, depending on the model). Intakes of fish, eggs, dairy, or plant protein sources were not associated with mortality. CONCLUSIONS: Higher ratio of animal to plant protein in diet and higher meat intake were associated with increased mortality risk. Higher total protein intake appeared to be associated with mortality mainly among those with a predisposing disease. This trial was registered at clinicaltrials.gov as NCT03221127.

Intake of different dietary proteins and risk of type 2 diabetes in men: the Kuopio Ischaemic Heart Disease Risk Factor Study.

The roles of different dietary proteins in the aetiology of type 2 diabetes (T2D) remain unclear. We investigated the associations of dietary proteins with the risk of incident T2D in Finnish men from the prospective Kuopio Ischaemic Heart Disease Risk Factor Study. The study included 2332 men aged 42-60 years at the baseline examinations in 1984-1989. Protein intakes were calculated from 4-d dietary records. Incident T2D was determined by self-administered questionnaires, fasting blood glucose measurements, 2-h oral glucose tolerance tests, and with national registers. The multivariable-adjusted risk of T2D on the basis of protein intakes was compared by the Cox proportional hazard ratios (HR). During the mean follow-up of 19·3 years, 432 incident T2D cases were identified. Total, animal, meat or dairy product protein intakes were not associated with risk of T2D when the potential confounders were accounted for. Plant (multivariable-adjusted extreme-quartile HR 0·65; 95 % CI 0·42, 1·00; P trend 0·04) and egg (HR 0·67; 95 % CI 0·44, 1·00; P trend 0·03) protein intakes were associated with a decreased risk of T2D. Adjustments for BMI, plasma glucose and serum insulin slightly attenuated associations. Replacing 1 % energy from carbohydrates with energy from protein was associated with a 5 % (95 % CI 0, 11) increased risk of T2D, but adjustment for fibre intake attenuated the association. Replacing 1 % of energy from animal protein with energy from plant protein was associated with 18 % (95 % CI 0, 32) decreased risk of T2D. This association remained after adjusting for BMI. In conclusion, favouring plant and egg proteins appeared to be beneficial in preventing T2D.
