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.

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.

What explains differences in waiting times for health care across socioeconomic status?

In publicly funded health systems, waiting times act as a rationing mechanism that should be based on need rather than socioeconomic status. However, several studies suggest that individuals with higher socioeconomic status wait less. Using individual-level data from administrative registers, we estimate and explain socioeconomic inequalities in access to publicly funded care for seven planned hospital procedures in Denmark. For each procedure, we first estimate the association between patients' waiting time for health care and their socioeconomic status as measured by income and education, controlling for patient severity. Then, we investigate how much of the association remains after controlling for (i) other individual characteristics (patients' family status, labor market status, and country of origin) that may be correlated with income and education, (ii) possible selection due to patients' use of a waiting time guarantee, and (iii) hospital factors which allow us to disentangle whether inequalities in waiting times arise across hospitals or within the hospital. Only for a few procedures, we find inequalities in waiting times related to income and education. These inequalities can be explained mostly by geographical and institutional factors across hospitals. But we also find inequalities for some procedures in relation to non-Western immigrants within hospitals.

Testing the myth of fee-for-service and overprovision in health care.

Paying on the basis of fee-for-service (FFS) is often associated with a risk of overprovision. Policymakers are therefore increasingly looking to other payment schemes to ensure a more efficient delivery of health care. This study tests whether context plays a role for overprovision under FFS. Using a laboratory experiment involving medical students, we test the extent of overprovision under FFS when the subjects face different fee sizes, patient types, and market conditions. We observe that decreasing the fee size has an effect on overprovision under both market conditions. We also observe that patients who are harmed by excess treatment are at little risk of overprovision. Finally, when subjects face resource constraints but still have an incentive to overprovide high-profit services, they hesitate to do so, implying that the presence of opportunity costs in terms of reduced benefits to other patients protects against overprovision. Thus, this study provides evidence that the risk of overprovision under FFS depends on fee sizes, patients' health profiles, and market conditions.

Individualized Therapy Is a Long-Term Cost-Effective Method Compared to Dose Intensification in Crohn's Disease Patients Failing Infliximab.

BACKGROUND: In Crohn's disease patients failing infliximab therapy, interventions defined by an algorithm based on infliximab and anti-infliximab antibody measurements have proven more cost-effective than intensifying the infliximab regimen. AIM: This study investigated long-term economic outcomes at the week 20 follow-up study visit and after 1 year. Clinical outcomes were assessed at week 20. METHODS: Follow-up from a 12-week, single-blind, clinical trial where patients with infliximab treatment failure were randomized to infliximab intensification (5 mg/kg every 4 weeks) (n = 36), or algorithm-defined interventions (n = 33). Accumulated costs, expressed as mean costs per patient, were based on the Danish National Patient Registry. RESULTS: At the scheduled week 20 follow-up study visit, response and remission rates were similar in all study subpopulations between patients treated by the algorithm or by infliximab intensification. However, the sum of healthcare costs related to Crohn's disease was substantially lower (31 %) for patients randomized to algorithm-based interventions than infliximab intensification in the intention-to-treat population: $11,940 versus $17,236; p = 0.005. For per-protocol patients (n = 55), costs at the week 20 follow-up visit were even lower (49 %) in the algorithm group: $8,742 versus $17,236; p = 0.002. Figures were similar for patients having completed the 12-week trial as per protocol (50 % reduction in costs) (n = 45). Among patients continuing the allocated study intervention throughout the entire 20-week follow-up period (n = 29), costs were reduced by 60 % in algorithm-treated patients: $7,056 versus $17,776; p < 0.001. Cost-reduction percentages remained stable throughout one year. CONCLUSION: Economic benefit of algorithm-based interventions at infliximab failure is maintained throughout 1 year.

Individualised therapy is more cost-effective than dose intensification in patients with Crohn's disease who lose response to anti-TNF treatment: a randomised, controlled trial.

OBJECTIVE: Although the reasons for secondary loss of response to infliximab (IFX) maintenance therapy in Crohn's disease vary, dose intensification is usually recommended. This study investigated the cost-effectiveness of interventions defined by an algorithm designed to identify specific reasons for therapeutic failure. DESIGN: Randomised, controlled, single-blind, multicentre study. 69 patients with secondary IFX failure were randomised to IFX dose intensification (5 mg/kg every 4 weeks) (n=36) or interventions based on serum IFX and IFX antibody levels using the proposed algorithm (n=33). Predefined co-primary end points at week 12 were proportion of patients responding (Crohn's Disease Activity Index (CDAI) decrease ≥ 70, or ≥ 50% reduction in active fistulas) and accumulated costs related to treatment of Crohn's disease, expressed as mean cost per patient, based on the Danish National Patient Registry for all hospitalisation and outpatient costs in the Danish healthcare sector. RESULTS: Costs for intention-to-treat patients were substantially lower (34%) for those treated in accordance with the algorithm than by IFX dose intensification: € 6038 vs € 9178, p<0.001. However, disease control, as judged by response rates, was similar: 58% and 53%, respectively, p=0.81; difference 5% (-19% to 28%). For per-protocol patients, treatment costs were even lower (56%) in the algorithm-treated group (€ 4062 vs € 9178, p<0.001) and with similar response rates (47% vs 53%, p=0.78; difference -5% (-33% to 22%)). CONCLUSIONS: Treatment of secondary IFX failure using an algorithm based on combined IFX and IFX antibody measurements significantly reduces average treatment costs per patient compared with routine IFX dose escalation and without any apparent negative effect on clinical efficacy.

Financial incentives for integrated care: A scoping review and lessons for evidence-based design.

BACKGROUND: In response to the increasing prevalence of people with chronic conditions, healthcare systems restructure to integrate care across providers. However, many systems fail to achieve the desired outcomes. One likely explanation is lack of financial incentives for integrating care. OBJECTIVES: We aim to identify financial incentives used to promote integrated care across different types of providers for patients with common chronic conditions and assess the evidence on (cost-)effectiveness and the facilitators/barriers to their implementation. METHODS: This scoping review identifies studies published before December 2021, and includes 33 studies from the United States and the Netherlands. RESULTS: We identify four types of financial incentives: shared savings, bundled payments, pay for performance, and pay for coordination. Substantial heterogeneity in the (cost-)effectiveness of these incentives exists. Key implementation barriers are a lack of infrastructure (e.g., electronic medical records, communication channels, and clinical guidelines). To facilitate integration, financial incentives should be easy to communicate and implement, and require additional financial support, IT support, training, and guidelines. CONCLUSIONS: All four types of financial incentives may promote integrated care but not in all contexts. Shared savings appears to be the most promising incentive type for promoting (cost-)effective care integration with the largest number of favourable studies allowing causal interpretations. The limited evidence pool makes it hard to draw firm conclusions that are transferable across contexts.

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.

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.

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].

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.

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.

Healthcare Costs, School Performance, and Health-related Quality of Life in Adolescence Following Psychotic Experiences in Preadolescence: A Longitudinal Cohort Study.

Psychotic experiences (PEs) are common in the general population in preadolescence. The implications of PEs on socioeconomic outcomes, including educational attainment, are scarcely described. We aimed to estimate how preadolescent PEs were associated with later healthcare costs, school performance, and health-related quality of life (HRQoL) in adolescence. A total of 1607 preadolescents from the general population Copenhagen Child Cohort 2000 were assessed for PEs at age 11-12 years and followed up over 5 years using register-based data on mental and somatic healthcare costs, and school performance at age 16. Furthermore, HRQoL was assessed for a subsample of the children at age 16-17. We adjusted for perinatal and family sociodemographic adversities, prior parental mental illness and healthcare use, child IQ-estimate at age 11-12, and parent-rated general psychopathology of their child. PEs were associated with slightly poorer school performance. However, preadolescents with PEs more often reported HRQoL within the lowest 10th percentile (OR = 2.74 [95% CI 1.71-4.37]). Preadolescents who reported PEs had higher average total healthcare costs over the following 5 years. The costs for individuals with PEs were higher for mental healthcare services across primary to tertiary care, but not for somatic care. After adjustments, PEs remained independently associated with higher costs and poorer HRQoL, but not with poorer school performance. In conclusion, PEs are important in mental health screening of preadolescents and identify a group of young people with increased healthcare service-use throughout adolescence and who report poorer HRQoL in adolescence, over and above parent-rated general psychopathology of their child.

Evaluation of a screening algorithm using the Strengths and Difficulties Questionnaire to identify children with mental health problems: A five-year register-based follow-up on school performance and healthcare use.

BACKGROUND: Treatment of mental health problems (MHP) is often delayed or absent due to the lack of systematic detection and early intervention. This study evaluates the potential of a new screening algorithm to identify children with MHP. METHODS: The study population comprises 2,015 children from the Copenhagen Child Cohort 2000 whose mental health was assessed at age 11-12 years and who had no prior use of specialised mental health services. A new algorithm based on the Strengths and Difficulties Questionnaire (SDQ) is utilised to identify MHP by combining parent-reported scores of emotional and behavioural problems and functional impairments. The screening is done on historical data, implying that neither parents, teachers nor health care professionals received any feedback on the screening status. The screening status and results of an IQ-test were linked to individual-level data from national registries. These national registers include records of each child's school performance at the end of compulsory schooling, their health care utilisation, as well as their parents' socio-economic status and health care utilisation. RESULTS: 10% of the children screen positive for MHP. The children with MHP achieve a significantly lower Grade Point Average on their exams, independently of their IQ-score, perinatal factors and parental characteristics. On average, the children with MHP also carry higher health care costs over a five-year follow-up period. The higher health care costs are only attributed to 23% of these children, while the remaining children with MHP also show poorer school performance but receive no additional health care. CONCLUSIONS: The results demonstrate that children with MHP and a poor prognosis can be identified by the use of the brief standardised questionnaire SDQ combined with a screening algorithm.

Uncertainty about the effort-performance relationship in threshold-based payment schemes.

Incentive schemes often feature a threshold beyond which providers receive no additional payment for performance. We investigate whether providers' uncertainty about the relationship between effort and measured performance leads to financially unrewarded performance in such schemes. Using data from the British Quality and Outcomes Framework, we proxy general practitioners' uncertainty about the effort-performance relationship by their experience with the scheme and their span of control. We find evidence that providers respond to uncertainty by exerting financially unrewarded performance, suggesting that uncertainty may be a mechanism by which payers can extract unrewarded performance.
