Is there a link between health care utilisation and subjective well-being? An exploratory study among older Danes.

While extensive research has explored the influence of traditional factors such as socioeconomic position on health care utilisation, the independent role of an individual's well-being in their health care seeking behaviour remains largely uncharted territory. In this study, we delve into the role of subjective well-being (SWB) in health care utilisation. We use a unique link between survey data from a representative group of Danish citizens aged 50-80 and administrative register data containing information on health care utilisation and sociodemographics. We explore whether SWB is a predictor of health care utilisation (general practice services) over and above health (as measured by health-related quality of life (HRQoL)). We find that the association between SWB and number of services provided in general practice differs across levels of HRQoL. Among those with lower HRQoL, we find a positive association between health care utilisation and SWB. Results hold true even when controlling for previous health care utilisation, suggesting that the mechanism is not driven by reverse causality. Our findings suggest that, in particular for vulnerable individuals in poor health and with poor SWB, the propensity to seek care is inappropriately low, and there is a need for more proactive supply-driven health care.

Do physicians' attitudes toward prioritization predict poor-health patients' access to care?

Physicians often face tight resource constraints, meaning they have to make trade-offs between which patients they care for and the amount of care received. Studies show that patients requiring many resources disproportionately suffer a loss of care when resources are constrained. This study uncovers whether physicians' attitudes toward prioritization of healthcare predicts poor-health patients' access to care. We combine unique survey data on Danish GPs' preferred prioritization principle with register data on their patients' contacts in general practice. We consider different types of contacts as the required effort could impact the need for prioritization. Our results show variation in GPs' prioritization principles, where a majority prefers a principle that may lead to an unequal distribution of services. We further find that GPs' attitudes toward prioritization predict some poor-health patients' access to general practice. GPs who state they prefer the principle of prioritizing patients in the poorest health state when resources tightened provide more contacts to poor-health patients. The additional contacts are typically high-effort contacts such as annual status meetings and home visits, but also low-effort contacts such as emails. Our findings indicate inequity in poor-health patients' access to care across general practices.

The link between physician motivation and care.

Studies report an unexplained variation in physicians' care. This variation may to some extent be explained by differences in their work motivation. However, empirical evidence on the link between physician motivation and care is scarce. We estimate the associations between different types of work motivation and care. Motivation is measured using validated questions from a nation-wide survey of Danish general practices and linked to high-quality register data on their care in 2019. Using a series of regression models, we find that more financially motivated practices generate more fee-for-services per patient, whereas practices characterised by greater altruistic motivation towards the patient serve a larger share of high-need patients and issue more prescriptions for antibiotics per patient. Practices with higher altruism towards society generate lower medication costs per patient and prescribe a higher rate of narrow-spectrum penicillin, thereby reducing the risk of antimicrobial resistance in the population. Together, our results suggest that practices' motivation is associated with several dimensions of healthcare, and that both their financial motivation and altruism towards patients and society play a role. Policymakers should, therefore, consider targeting all provider motivations when introducing organisational changes and incentive schemes; for example, by paying physicians to adhere to clinical guidelines, while at the same time clearly communicating the guidelines' value from both a patient and societal perspective.

Going the extra mile? General practitioners' upcoding of fees for home visits.

General practitioners' (GPs') income often relies on self-reported activities and performances. They can therefore 'game the system' to maximize their remuneration. We investigate whether Danish GPs game their travel fees for home visits. Combining administrative and geographical data, we measure the difference between GPs' traveled and billed distances. We exploit a rise in the fees for home visits. If there is a link between the rise in fees and upcoding, we interpret this finding as indicative of gaming behavior. We find that upcoding occurs slightly more often than downcoding (16% vs. 13% of visits) for visits that can be both upcoded and downcoded. Using linear probability models with GP fixed effects, we find that the fee rise is associated with a reduction in upcoding of 0.6% of home visits (2.8% for visits where upcoding is feasible) and no change in downcoding. Importantly, we find no statistically significant differences in the reduction in upcoding across distance bands despite large differences in their fee rises. We therefore conclude that there is no causal evidence of GPs gaming their fees.

Mapping GPs' motivation ­ it's not all about the money: a nationwide cross-sectional survey study from Denmark.

BACKGROUND: Understanding physicians' motivation may be essential for policymakers if they are to design policies that cater to physicians' wellbeing, job retention, and quality of care. However, physicians' motivation remains an understudied area. AIM: To map GPs' work motivation. DESIGN AND SETTING: A cross-sectional analysis using registry and survey data from Denmark. METHOD: Survey data were used to measure four types of motivation: extrinsic motivation, intrinsic motivation, user orientation, and public service motivation. These were combined with register data on the characteristics of the GP, practice, and area. Using latent profile analysis, the heterogeneity in GPs' motivation was explored; the associations between GPs' motivation and the GP, practice, and area characteristics were estimated using linear regression analyses. RESULTS: There was substantial heterogeneity in GPs' motivations. Five classes of GPs were identified with different work motivations: class 1 'it is less about the money' - probability of class membership 53.2%; class 2 'it is about everything' - 26.5%; class 3 'it is about helping others' - 8.6%; class 4 'it is about the work' - 8.2%; and class 5 'it is about the money and the patient' - 3.5%. Linear regression analyses showed that motivation was associated with GP, practice, and area characteristics to a limited extent only. CONCLUSION: GPs differ in their work motivations. The finding that, for many GPs, 'it is not all about the money' indicated that their different motivations should be considered when designing new policies and organisational structures to retain the workforce and ensure a high quality of care.

Cost-effectiveness of a transdiagnostic psychotherapy program for youth with common mental health problems.

OBJECTIVES: Our objective was to evaluate the cost-effectiveness of the transdiagnostic psychotherapy program Mind My Mind (MMM) for youth with common mental health problems using a cost-utility analysis (CUA) framework and data from a randomized controlled trial. Furthermore, we analyzed the impact of the choice of informant for both quality-of-life reporting and preference weights on the Incremental Cost-Effectiveness Ratio (ICER). METHODS: A total of 396 school-aged (6-16 years) youth took part in the 6-month trial carried out in Denmark. CUAs were carried out for the trial period and four one-year extrapolation scenarios. Costs were based on a combination of budget and self-reported costs. Youths and parents were asked to report on the youth's quality-of-life three times during the trial using the Child Health Utility 9D (CHU9D). Parental-reported CHU9D was used in the base case together with preference weights of a youth population. Analyses using self-reported CHU9D and preference weights of an adult population were also carried out. RESULTS: The analysis of the trial period resulted in an ICER of €170,465. The analyses of the one-year scenarios resulted in ICERs between €23,653 and €50,480. The ICER increased by 24% and 71% compared to the base case when using self-reported CHU9D and adult preference weights, respectively. CONCLUSION: The MMM intervention has the potential to be cost-effective, but the ICER is dependent on the duration of the treatment effects. Results varied significantly with the choice of informant and the choice of preference weights indicating that both factors should be considered when assessing CUA involving youth.

Public versus patient health preferences: protocol for a study to elicit EQ-5D-5L health state valuations for patients who have survived a stay in intensive care.

INTRODUCTION: The value set used when calculating quality-adjusted life-years (QALYs) is most often based on stated preference data elicited from a representative sample of the general population. However, having a severe disease may alter a person's health preferences, which may imply that, for some patient groups, experienced QALYs may differ from those that are estimated via standard methods. This study aims to model 5-level EuroQol 5-dimensional questionnaire (EQ-5D-5L) valuations based on preferences elicited from a sample of patients who have survived a stay in a Danish intensive care unit (ICU) and to compare these with the preferences of the general population. Further, the heterogeneity in the ICU patients' preferences will be investigated. METHODS AND ANALYSIS: This valuation study will elicit EQ-5D-5L health state preferences from a sample of 300 respondents enrolled in two randomised controlled trials at Danish ICUs. Patients' preferences will be elicited using composite time trade-off based on the EuroQol Valuation Technology, the same as that used to generate the EQ-5D-5L value set for the Danish general population. The patient-based and the public-based EQ-5D-5L valuations will be compared. Potential underlying determinants of the ICU preferences will be investigated through analyses of demographic characteristics, time since the ICU stay, self-reported health, willingness to trade-off length of life for quality of life, health state reference dependency and EQ-5D dimensions that patients have experienced themselves during their illness. ETHICS AND DISSEMINATION: Under Danish regulations, ethical approval is not required for studies of this type. Written informed consent will be obtained from all patients. The study results will be published in peer-reviewed scientific journals and presented at national and international conferences. The modelling algorithms will be publicly available for statistical software, such as Stata and R.

Age, morbidity, or something else? A residual approach using microdata to measure the impact of technological progress on health care expenditure.

This study measures the increment of health care expenditure (HCE) that can be attributed to technological progress and change in medical practice by using a residual approach and microdata. We examine repeated cross-sections of individuals experiencing an initial health shock at different point in time over a 10-year window and capture the impact of unobservable technology and medical practice to which they are exposed after allowing for differences in health and socioeconomic characteristics. We decompose the residual increment in the part that is due to the effect of delaying time to death, that is, individuals surviving longer after a health shock and thus contributing longer to the demand of care, and the part that is due to increasing intensity of resource use, that is, the basket of services becoming more expensive to allow for the cost of innovation. We use data from the Danish National Health System that offers universal coverage and is free of charge at the point of access. We find that technological progress and change in medical practice can explain about 60% of the increment of HCE, in line with macroeconomic studies that traditionally investigate this subject.

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.

Physicians under Pressure: Evidence from Antibiotics Prescribing in England.

BACKGROUND: Many physicians are experiencing increasing demands from both their patients and society. Evidence is scarce on the consequences of the pressure on physicians' decision making. We present a theoretical framework and predict that increasing pressure may make physicians disregard societal welfare when treating patients. SETTING: We test our prediction on general practitioners' antibiotic-prescribing choices. Because prescribing broad-spectrum antibiotics does not require microbiological testing, it can be performed more quickly than prescribing for narrow-spectrum antibiotics and is therefore often preferred by the patient. In contrast, from a societal perspective, inappropriate prescribing of broad-spectrum antibiotics should be minimized as it may contribute to antimicrobial resistance in the general population. METHODS: We combine longitudinal survey data and administrative data from 2010 to 2017 to create a balanced panel of up to 1072 English general practitioners (GPs). Using a series of linear models with GP fixed effects, we estimate the importance of different sources of pressure for GPs' prescribing. RESULTS: We find that the percentage of broad-spectrum antibiotics prescribed increases by 6.4% as pressure increases on English GPs. The link between pressure and prescribing holds for different sources of pressure. CONCLUSIONS: Our findings suggest that there may be societal costs of physicians working under pressure. Policy makers need to take these costs into account when evaluating existing policies as well as when introducing new policies affecting physicians' work pressure. An important avenue for further research is also to determine the underlying mechanisms related to the different sources of pressure.JEL-code: I11, J28, J45. HIGHLIGHTS: Many physicians are working under increasing pressure.We test the importance of pressure on physicians' prescribing of antibiotics.The prescribed rate of broad-spectrum antibiotics increases with pressure.Policy makers should be aware of the societal costs of pressured physicians.[Formula: see text].

Systematic identification and stratification of help-seeking school-aged youth with mental health problems: a novel approach to stage-based stepped-care.

We investigated whether a novel visitation model for school-aged youth with mental health problems based on a stage-based stepped-care approach facilitated a systematic identification and stratification process without problems with equity in access. The visitation model was developed within the context of evaluating a new transdiagnostic early treatment for youth with anxiety, depressive symptoms, and/or behavioural problems. The model aimed to identify youth with mental health problems requiring an intervention, and to stratify the youth into three groups with increasing severity of problems. This was accomplished using a two-phase stratification process involving a web-based assessment and a semi-structured psychopathological interview of the youth and parents. To assess problems with inequity in access, individual-level socioeconomic data were obtained from national registers with data on both the youth participating in the visitation and the background population. Altogether, 573 youth and their parents took part in the visitation process. Seventy-five (13%) youth had mental health problems below the intervention threshold, 396 (69%) were deemed eligible for the early treatment, and 52 (9%) had symptoms of severe mental health problems. Fifty (9%) youth were excluded for other reasons. Eighty percent of the 396 youth eligible for early treatment fulfilled criteria of a mental disorder. The severity of mental health problems highlights the urgent need for a systematic approach. Potential problems in reaching youth of less resourceful parents, and older youth were identified. These findings can help ensure that actions are taken to avoid equity problems in future mental health care implementations.

Effects of parental health shocks on children's school achievements: A register-based population study.

This paper studies how a severe parental health shock affects children's school achievements using a rich longitudinal dataset of Danish children. We use coarsened exact matching to control for potential endogeneity between parental health and children's school outcomes and employ cancer specific survival rates to measure the size of the health shock. We find robust negative (albeit small) effects of a parental health shock on children's basic school grades as well as their likelihood of starting and finishing secondary education, especially for poor prognosis cancers. We observe different outcomes across children's gender and age and gender of the ill parent, but no effects of family-related resilience factors such as parental education level. The effects appear to be driven by non-pecuniary costs rather than by pecuniary costs. Moreover, we find that the negative effects on school performance increase in the size of the health shock for both survivors and non-survivors.

Pure altruism and misjudgement: A bad combination?

Stated preference studies on the value of health risk reductions have found valuations elicited from a private perspective to be both higher and lower compared to valuations elicited from a public perspective. Although relevant, the individual's ability to correctly predict the valuation that other individuals assign to the risk reduction has been insufficiently researched. We aim to verify whether individuals exhibit pure altruistic preferences and if this is the case, whether the presence of pure altruism leads to biased valuation of public risk reductions due to misjudgement about other individuals' preferences. We conduct a large-scale online incentivised experiment as a variant of a public good game in which the individual's final endowment is determined by choices made in the experiment. Results suggest that individuals act as pure altruists and hence try to account for the benefits obtained by others of being insured. The results also suggest that individuals fail to correctly predict other individuals' benefits from the insurance, which leads to non-optimal outcomes and biased valuations.

Post robotic investment: Cost consequences and impact on length of stay for obese women with endometrial cancer.

INTRODUCTION: The aim of the study was to investigate whether robotic-assisted surgery is associated with lower incremental resource use among obese patients relative to non-obese patients after a Danish nationwide adoption of robotic-assisted surgery in women with early-stage endometrial cancer. This is a population-based cohort study based on registers and clinical data. MATERIAL AND METHODS: All women who underwent surgery (robotic, laparoscopic and laparotomy) from 2008 to 2015 were included and divided according to body mass index (<30 and ≥30). Robotic-assisted surgery was gradually introduced in Denmark (2008-2013). We compared resource use post-surgery in obese vs non-obese women who underwent surgery before and after a nationwide adoption of robotic-assisted surgery. The key exposure variable was exposure to robotic-assisted surgery. Clinical and sociodemographic data were linked with national register data to determine costs and bed days 12 months before and after surgery applying difference-in-difference analyses. RESULTS: In total, 3934 women were included. The adoption of robotic-assisted surgery did not demonstrate statistically significant implications for total costs among obese women (€3,417; 95% confidence interval [CI] -€854 to €7,688, p = 0.117). Further, for obese women, a statistically significant reduction in bed days related to the index hospitalization was demonstrated (-1.9 bed days; 95% CI -3.6 to -0.2, p = 0.025). However, for non-obese women, the adoption of robotic-assisted surgery was associated with statistically significant total costs increments of €9,333 (95% CI €3,729-€1,4936, p = 0.001) and no reduction in bed days related to the index hospitalization was observed (+0.9 bed days; 95% CI -0.6 to 2.3, p = 0.242). CONCLUSIONS: The national investment in robotic-assisted surgery for endometrial cancer seems to have more modest cost implications post-surgery for obese women. This may be partly driven by a significant reduction in bed days related to the index hospitalization among obese women, as well as reductions in subsequent hospitalizations.

Time to retire? A register-based study of GPs' practice style prior to retirement.

In many healthcare systems a large share of general practitioners (GPs) is retiring. The literature has shown a negative correlation between physicians' age and their quality of care. However, little is known about whether GPs exhibit different practice styles in the years prior to retirement. This study investigates whether GPs who are closer to retirement make different professional choices than GPs who are not as close to retirement. Using detailed administrative data on 555 Danish GPs and their patients from 2005 to 2017, we study GPs' practice styles across a ten-year period prior to retirement and compare these with GPs who retire at a later date ('non-retiring GPs'), while controlling for age differences as well as exogenous factors affecting healthcare provision. We focus on the GPs' number of enlisted patients, revenue, provision of consultations, and treatment behaviour in consultations. We find no differences between retiring and non-retiring GPs for key outcomes such as 'revenue per patient' and 'consultations per patient'. However, we find that retiring GPs have fewer enlisted patients in their final years of practicing. This finding is driven by more patients leaving rather than fewer patients joining their lists. We also find that retirement is associated with other dimensions of GPs' practice style, e.g. their provision of home visits, prescribing, and referral rates. Overall, we find a modest association between GPs' retirement and their practice style.

Allocation of health care under pay for performance: Winners and losers.

Many physicians receive a payment for their performance (P4P). This performance is often linked to a health target that triggers a bonus when met. For some patients the target is easily met, while others require a significant amount of care to reach the target (if ever). This study contributes to the literature by providing evidence of how P4P affects allocation of care across patients with low and high responsiveness to treatment compared to a fixed payment, such as capitation and salary, under different degrees of resource constraint. Our evidence is based on a controlled laboratory experiment involving 143 medical students in Denmark in 2019. We find that patients who have the potential to reach the health target, gain care under P4P, whereas patients with no potential to reach it, may receive less care. Redistribution of care between patients under P4P arises when physicians are resource constrained. As many physicians are currently operating under tight resource constraints, policymakers should be careful to avoid unintended inequalities in patients' access to health care when introducing P4P. Risk-adjusting the performance target may potentially solve this issue.

Home sweet home: GPs' response to an increase in the fee size for home visits.

In many health care systems GPs receive fees for their services. Policymakers may use the size of these fees to try to incentivise GPs to provide more care. However, evidence is mixed on whether and how GPs respond to an increase in the fee size. This study investigates how GPs respond to an average increase of 150% in the fee for a high-effort and infrequent service such as a home visit due to patients' illness. We consider Danish GPs' provision of these visits to enlisted patients living outside of nursing homes. Using linear regressions with general practice fixed effects and a rich number of control variables, we estimate the association between GPs' provision of these home visits and the fee rise. On average, we find no association between the fee rise and GPs' provision of home visits. However, we find that GPs who previously provided the fewest home visits to eligible patients increase their provision by 13% after the fee rise compared to other GPs. This increase in visits is driven by more patients receiving multiple visits after the fee rise. We conclude that a fee rise may not yield a strong response in GPs' provision of high-effort and infrequent services such as home visits.

Sample restrictions and the elicitation of a constant willingness to pay per quality adjusted life year.

It is well established that the underlying theoretical assumptions needed to obtain a constant proportional trade-off between a quality adjusted life year (QALY) and willingness to pay (WTP) are restrictive and often empirically violated. In this paper, we set out to investigate whether the proportionality conditions (in terms of scope insensitivity and severity independence) can be satisfied when data is restricted to include only respondents who pass certain consistency criteria. We hypothesize that the more we restrict the data, the better the compliance with the requirement of constant proportional trade-off between WTP and QALY. We revisit the Danish data from the European Value of a QALY survey eliciting individual WTP for a QALY (WTP-Q). Using a "chained approach" respondents were first asked to value a specified health state using the standard gamble (SG) or the time-trade-off (TTO) approach and subsequently asked their WTP for QALY gains of 0.05 and 0.1 (tailored according to the respondent's SG/TTO valuation). Analyzing the impact of the different exclusion criteria on the two proportionality conditions, we find strong evidence against a constant WTP-Q. Restricting our data to include only respondents who pass the most stringent consistency criteria does not impact on the performance of the proportionality conditions for WTP-Q.

GP decisions to participate in emergencies: a randomised vignette study.

BACKGROUND: GPs use their judgement on whether to participate in emergencies; however, little is known about how GPs make their decisions on emergency participation. AIM: To test whether GPs' participation in emergencies is associated with cause of symptoms, distance to the patient, other patients waiting, and out-of-hours (OOH) clinic characteristics. DESIGN & SETTING: An online survey was sent to all GPs in Norway (n = 4701). METHOD: GPs were randomised to vignettes describing a patient with acute shortness of breath and asked whether they would participate in a callout. The vignettes varied with respect to cause of symptoms (trauma versus illness), distance to the patient (15 minutes versus 45 minutes), and other patients waiting at the OOH clinic (crowding versus no crowding). The survey included questions about OOH clinic characteristics. RESULTS: Of the 1013 GPs (22%) who responded, 76% reported that they would participate. The proportion was higher in trauma (83% versus 69%, χ2 24.8, P<0.001), short distances (80% versus 71%, χ2 9.5, P=0.002), and no crowding (81% versus 70% χ2 14.6, P<0.001). Participation was associated with availability of a manned-response vehicle (adjusted odds ratio [OR] 2.06, 95% confidence interval [CI] = 1.25 to 3.41), and team training at the OOH clinic once a year (OR = 1.78, 95% CI = 1.12 to 2.82) or more than once a year (OR = 3.78, 95% CI = 1.64 to 8.68). CONCLUSION: GPs were less likely to participate in emergencies when the incident was not owing to trauma, was far away, and when other patients were waiting. A manned-response vehicle and regular team training were associated with increased participation.

The relative value of different QALY types.

The oft-applied assumption in the use of Quality Adjusted Life Years (QALYs) in economic evaluation, that all QALYs are valued equally, has been questioned from the outset. The literature has focused on differential values of a QALY based on equity considerations such as the characteristics of the beneficiaries of the QALYs. However, a key characteristic which may affect the value of a QALY is the type of QALY itself. QALY gains can be generated purely by gains in survival, purely by improvements in quality of life, or by changes in both. Using a discrete choice experiment and a new methodological approach to the derivation of relative weights, we undertake the first direct and systematic exploration of the relative weight accorded different QALY types and do so in the presence of equity considerations; age and severity. Results provide new evidence against the normative starting point that all QALYs are valued equally.
