Factors Contributing to Variations in Physicians' Use of Evidence at The Point of Care: A Conceptual Model

It's a jungle out there: Understanding physician payment and its role in group dynamics

Although collaboration between healthcare professionals is essential for the delivery of effective, efficient, and high-quality care, it remains an ongoing and critical challenge across health systems. As a result, many countries are experimenting with innovative payment and employment models. The literature tends to focus on improving collaboration across organizational and sectoral boundaries, and largely ignores potential barriers to collaborative work between members of the same profession within a single organization. Despite intergroup dynamics and professional boundaries having been shown to restrict patient flow and collaboration between specialties, studies have so far tended to overlook the potential effects of differentiated organizational and payment models on physicians' behaviors and intergroup dynamics. In the present study, we seek to unpack the influence of physicians' payment and employment models on their collaborative behaviors and on intergroup dynamics between specialties, adding to the current scholarship on physician payment and employment by considering how physicians' view and act in response to different structural arrangements. The findings suggest that adopting hybrid models, in which physicians are employed or paid differently within the same organization or practice, creates a bifurcation of the profession whereby physicians across different models are perceived to behave differently and have conflicting professional values. These models are perceived to inhibit collaboration between physicians and complicate hospital governance, restricting the ability to move towards new models of care delivery. These findings can be used as a basis for future work that aims to unpack the reality of physician payment and offer important insights for policies surrounding physician employment.

Atypical Antipsychotic Prescribing in Australian Children and Adolescents: A Survey of Medical Practitioners

OBJECTIVE

Prescriptions for atypical antipsychotics in children and adolescents are increasing globally. However, a precise understanding of the clinical variables and evidence that prescribers consider before using these agents is lacking. While empirical literature on the long-term safety and efficacy of these medications is available, the literature concerning their use in these younger age groups is relatively sparse. In this study, we examined the current prescribing patterns of medical professionals employed by a public health service in Australia.

METHODS

A survey examining their current practice when prescribing atypical antipsychotics to children and adolescents was completed by 103 physicians. Questions were asked about commonly prescribed atypical antipsychotics, indications, dose ranges, target symptoms, duration of treatment, and the evidence base(s) used when making treatment decisions.

RESULTS

Physicians prescribed atypical antipsychotics for a wide range of indications in this age group, with the most common agents being risperidone, quetiapine, and olanzapine. Adverse effects were reported as the main reason for treatment discontinuation. More than half of the respondents indicated that the most common source of guidance/evidence they referred to when initiating prescriptions were peers or expert opinion.

CONCLUSIONS

Children and adolescents were prescribed a number of atypical antipsychotics for a variety of indications, with variable perceived confidence and a relatively heavy reliance on "own or peer experience" as opposed to good quality evidence. Challenges exist for both prescribers and policymakers, and further "head-to-head" studies are needed in this age group to ensure that a balance is maintained between therapeutic benefit and safety.

Kidney Transplantation Contraindications: Variation in Nephrologist Practice and Training Vintage

Introduction

Health system leaders aim to increase access to kidney transplantation in part by encouraging nephrologists to refer more patients for transplant evaluation. Little is known about nephrologists' referral decisions and whether nephrologists with older training vintage weigh patient criteria differently (e.g., more restrictively).

Methods

Using a novel, iteratively validated survey of US-based nephrologists, we examined how nephrologists assess adult patients' suitability for transplant, focusing on established, important criteria: 7 clinical (e.g., overweight) and 7 psychosocial (e.g., insurance). We quantified variation in nephrologist restrictiveness-proportion of criteria interpreted as absolute or partial contraindications versus minor or negligible concerns-and tested associations between restrictiveness and nephrologist age (proxy for training vintage) in logistic regression models, controlling for nephrologist-level and practice-level factors.

Results

Of 144 nephrologists invited, 42 survey respondents (29% response rate) were 85% male and 54% non-Hispanic White, with mean age 52 years, and 67% spent ≥1 day/wk in outpatient dialysis facilities. Nephrologists interpreted patient criteria inconsistently; consistency was lower for psychosocial criteria (intraclass correlation coefficient: 0.28) than for clinical criteria (intraclass correlation coefficient: 0.43; P < 0.01). With each additional 10 years of age, nephrologists' odds of interpreting criteria restrictively (top tertile) doubled (adjusted odds ratio [aOR] 1.96; 95% confidence interval [CI]: 0.95-4.07), with marginal statistical significance. This relationship was significant when interpreting psychosocial criteria (aOR: 3.18; 95% CI: 1.16-8.71) but not when interpreting clinical criteria (aOR: 1.12; 95% CI: 0.52-2.38).

Conclusion

Nephrologists interpret evaluation criteria variably when assessing patient suitability for transplant. Guideline-based educational interventions could influence nephrologists' referral decision-making differentially by age.

Associations between demographics and clinical ideology, beliefs, and practice patterns: a secondary analysis of a survey of randomly sampled United States chiropractors

BACKGROUND

The chiropractic profession in the United States (US) has a long history of intra-professional discourse surrounding ideology and beliefs. Large-scale efforts have evaluated 3 distinctive subgroups of US chiropractors focused on these areas of practice: spine/neuromusculoskeletal, primary care, and vertebral subluxation. To our knowledge, there have not been any prior studies exploring the factors associated with these ideology and belief characteristics of these subgroups. The purpose of this study was to explore, describe, and characterize the association of US chiropractors' ideology, beliefs, and practice patterns with: 1) chiropractic degree program of graduation, 2) years since completion of chiropractic degree, and 3) US geographic region of primary practice.

METHODS

This was a secondary analysis of a cross-sectional survey of a random sample of US licensed chiropractors (n = 8975). A 10% random sample was extracted from each of the 50 states and District of Columbia chiropractic regulatory board lists. The survey was conducted between March 2018-January 2020. The survey instrument consisted of 7 items that were developed to elicit these differentiating ideologies, beliefs, and practice patterns: 1) clinical examination/assessment, 2) health conditions treated, 3) role of chiropractors in the healthcare system, 4) the impact of chiropractic adjustments [spinal manipulation] in treating patients with cancer, 5) vaccination attitudes, 6) detection of subluxation on x-ray, and 7) x-ray utilization rates. Multinomial regression was used to analyze associations between these 7 ideology and practice characteristic items from the survey (dependent variables) and the 3 demographic items listed above (independent variables).

RESULTS

Data from 3538 respondents (74.6% male) were collected with an overall response rate of 39.4%. Patterns of responses to the 7 survey items for ideologies, beliefs, and practice characteristics were significantly different based on chiropractic degree program of graduation, years since completion of chiropractic degree, and geographic region of primary practice.

CONCLUSIONS

Among US chiropractors, chiropractic program of graduation, years since completion of chiropractic degree, and geographic region of primary practice are associated with variations in clinical ideology, beliefs, and practice patterns. The wide variation and inconsistent beliefs of US chiropractors could result in public confusion and impede interprofessional integration.

Unravelling the determinants of medical practice variation in referrals among primary care physicians: insights from a retrospective cohort study in Southern Israel

OBJECTIVES

Reducing medical practice variation (MPV) is a central theme of system improvement because it is associated with poor health outcomes, increased costs and disparities in care. This study aimed to estimate the extent to which each determinant (patient, physician, clinic) explains MPV among primary care physicians and to identify the characteristics of health services with a greater explained variance.

METHODS

A retrospective cohort study of primary care physicians practising in non-private clinics of Clalit Health Services in Southern Israel, for longer than a year between 2011 and 2017 and with more than 100 adult patients per practice. We assessed the variation in referral rates among 17 health services and the proportion explained by each domain (patient, physician and clinic). We used generalised linear negative binomial mixed models and the Nakagawa's R2, computing the marginal r2.

RESULTS

The study included 243 physicians working in 295 practices and 139 clinics. The mean-explained variance was 28.5%±10.0%, where physician characteristics explained 4.5% of the variation. The intrapractice variation (within a single physician between the years) was explained better than the interphysician (between physicians). Health services with high explained variation were blood tests characterised by both low intrapractice variation (Rs=-0.65, p value=0.005) and high referral rates (Rs=0.46, p value=0.06).

CONCLUSION

Over 70% of MPV is not explained by the patient, clinic and physician demographic and professional characteristics. Future research should focus on the fraction of MPV that is explained by the physicians' psychological characteristics, and thus potentially identify psychological targets for behavioural modifications aimed at reducing MPV.

Practice Billing for Medicare Advance Care Planning Across the USA

BACKGROUND

Medicare introduced billing codes in 2016 to encourage clinicians to engage in advance care planning (ACP) and promote goal-concordantend-of-life care, but uptake has been modest. While prior research examined individual-level factors in ACP billing, organization-level factors associated with physician practices billing for ACP remain unknown.

OBJECTIVE

Examine the role of practices in ACP billing.

DESIGN

Retrospective cohort study analyzing 2016-2018 national Medicare data.

PARTICIPANTS

A total of 53,926 practices with at least 10 attributed Medicare beneficiaries.

MAIN MEASURES

Outcomes were practice-level ACP billing (any use by the practice) and ACP use rate by practice-attributed beneficiaries. Practice characteristics were number of beneficiaries attributed to the practice; percentage of beneficiaries by race, Medicare-Medicaid dual enrollment, sex, and age; practice size; and specialty mix.

KEY RESULTS

Fifteen percent of practices billed for ACP. In adjusted models, we found higher odds of ACP billing and higher ACP use rates among practices with more primary care physicians (billing AOR: 10.01, 95%CI: 8.81-11.38 for practices with 75-100% (vs 0) primary care physicians), and those serving more Medicare beneficiaries (billing AOR: 4.55, 95%CI 4.08-5.08 for practices with highest (vs lowest) quintile of beneficiaries), and larger shares of female beneficiaries (billing AOR: 3.06, 95% CI 2.01-4.67 for 75-100% (vs <25%) female ).

CONCLUSIONS

Several years after Medicare introduced ACP reimbursements for physicians, relatively few practices bill for ACP. ACP billing was more likely in large practices with a greater percentage of primary care physicians. To increase ACP billing uptake, policymakers and health system leaders might target interventions to larger practices where a small number of physicians already bill for ACP and to specialty practices that serve as the primary source of care for seriously ill patients.

Predicting Fragmented Care: Beneficiary, Physician, Practice, and Market Characteristics

BACKGROUND

Understanding what drives fragmented ambulatory care (care spread across multiple providers without a dominant provider) can inform the design of future interventions to reduce unnecessary fragmentation.

OBJECTIVES

To identify the characteristics of beneficiaries, primary care physicians, primary care practice sites, and geographic markets that predict highly fragmented ambulatory care in the United States.

RESEARCH DESIGN

Cross-sectional analysis of Medicare claims data for beneficiaries attributed to primary care physicians and practices in 2018. We used hierarchical linear models with random intercepts and an extensive list of explanatory variables to predict the likelihood of high fragmentation.

SUBJECTS

A total of 3,540,310 Medicare fee-for-service beneficiaries met the inclusion criteria, attributed to 26,344 primary care physicians in 9300 practice sites, and 788 geographic markets.

MEASURES

We defined high care fragmentation as a reversed Bice-Boxerman Index score above 0.85.

RESULTS

Explanatory variables explained only 6% of the variation in highly fragmented care. Unobserved differences between primary care physicians, between practice sites, and between markets together accounted for 4%. Instead, 90% of the variation in high fragmentation was unobserved residual variance. We identified the characteristics of beneficiaries (age, reason for original Medicare entitlement, and dually eligible for Medicaid insurance), physicians (comprehensiveness of care), and practices (size, being part of a system/hospital) that had small associations with high fragmentation.

CONCLUSIONS

Variation in fragmentation was not explained by observed beneficiary, primary care provider, practice site, or market characteristics. Instead, the aggregate behavior of diverse health care providers beyond primary care, along with unmeasured patient preferences and behaviors, seem to be important predictors.

Educational considerations based on medical student use of polygenic risk information and apparent race in a simulated consultation

PURPOSE

To craft evidence-based educational approaches related to polygenic risk score (PRS) implementation, it is crucial to forecast issues and biases that may arise when PRS are introduced in clinical care.

METHODS

Medical students (N = 84) were randomized to a simulated primary care encounter with a Black or White virtual reality-based patient and received either a direct-to-consumer-style PRS report for 5 common complex conditions or control information. The virtual patient inquired about 2 health concerns and her genetic report in the encounter. Data sources included participants' verbalizations in the simulation, care plan recommendations, and self-report outcomes.

RESULTS

When medical students received PRSs, they rated the patient as less healthy and requiring more strict advice. Patterns suggest that PRSs influenced specific medical recommendations related to the patient's concerns, despite student reports that participants did not use it for that purpose. We observed complex patterns regarding the effect of patient race on recommendations and behaviors.

CONCLUSION

Educational approaches should consider potential unintentional influences of PRSs on decision-making and evaluate ways that they may be applied inconsistently across patients from different racial groups.

A scoping review of medical practice variation research within the informatics literature

RATIONALE

We performed a scoping review of informatics core literature about medical practice variation (MPV) as an agile summary of the subject in our field.

MATERIALS AND METHODS

The Ovid integrated database was searched between 1946 and 2022 to identify MPV studies published in major informatics journals and conference proceedings. Two reviewers performed relevance screening, with assistance from another independent reviewer for adjudication. The included articles were then thematically analyzed and summarized through discussion among all three reviewers.

RESULTS

A total of 43 articles were included and went through the thematic analysis. About half (n = 21) of the included articles were published in conference proceedings. Five articles reported the effect of MPV on patient outcomes. The variation of interest was most frequently in treatment decisions. In terms of the role informatics played (multiple roles allowed), 39 (90.7%) articles pertained to detection of MPV, 5 were about prevention of MPV and 4 about learning from MPV.

DISCUSSION

MPV remains a critical issue in health care, yet most informatics research has been focused on simple tasks such as automating the detection of MPV and assessing compliance to decision-support systems, and less focused on addressing the causes of variation or supporting learning from variation.

CONCLUSION

Our scoping review found that informatics studies have focused on detecting of MPV, especially variability in treatments and deviation from practice guidelines. Technological advances should promote more informatics research focused on explaining and learning from MPV.

Adoption of Patient Engagement Strategies by Physician Practices in the United States

BACKGROUND

Patient engagement strategies can equip patients with tools to navigate treatment decisions and improve patient-centered outcomes. Despite increased recognition about the importance of patient engagement, little is known about the extent of physician practice adoption of patient engagement strategies nationally.

METHODS

We analyzed data collected from the National Survey of Healthcare Organizations and Systems (NSHOS) on physician practice adoption of patient engagement strategies. Stratified-cluster sampling was used to select physician practices operating under different organizational structures. Multivariable linear regression models estimated the association of practice ownership, health information technology functionality, use of screening activities, patient responsiveness, chronic care management processes, and the adoption of patient engagement strategies, including shared decision-making, motivational interviewing, and shared medical appointments. All regression models controlled for participation in payment reforms, practice size, Medicaid revenue percentage, and geographic region.

RESULTS

We found modest and varied adoption of patient engagement strategies by practices of different ownership types, with health system-owned practices having the lowest adoption of ownership types. Practice capabilities, including chronic care management processes, routine screening of medical and social risks, and patient care dissemination strategies were associated with greater practice-level adoption of patient engagement strategies.

CONCLUSIONS

This national study is the first to characterize the adoption of patient engagement strategies by US physician practices. We found modest adoption of shared decision-making and motivational interviewing, and low adoption of shared medical appointments. Risk-based payment reform has the potential to motivate greater practice-level patient engagement, but the extent to which it occurs may depend on internal practice capabilities.

Multilevel Influences on Providers' Delivery of Contraceptive Services: A Qualitative Thematic Analysis

Introduction:

Access to a full range of contraceptive services is essential for quality health care. Contraceptive provision practices of primary care providers play an important role in patients' decision-making about their reproductive health care. Understanding the multilevel factors influencing contraceptive care delivery in primary care settings is critical for advancing quality care. This study offers an in-depth examination of influences on providers' delivery of contraceptive services across multiple primary care specialties and practice settings to identify issues and strategies to improve care.

Materials and Methods:

Twenty-four in-depth face-to-face interviews were conducted in 2017 with primary care providers, including family physicians, gynecologists, pediatricians, and nurse practitioners from academic settings, private practices, and health centers. Interviews were transcribed and analyzed thematically.

Results:

Providers described a complex set of influences on their provision of contraception across multiple ecological contexts. Seven major themes emerged from the qualitative analysis, including six types of influence on provision of contraception: organizational, individual provider-related, structural and policy, individual patient-related, community, and the lack of influences or barriers. Providers also discussed the sources they access for information about evidence-based contraception counseling.

Conclusions:

A diverse set of providers described a complex system in which multiple concentric ecological contexts both positively and negatively influence the ways in which they provide contraceptive services to their patients. To close the gaps in contraceptive service delivery, it is important to recognize that both barriers and facilitators to patient-centered contraceptive counseling exist simultaneously across multiple ecological contexts.

Factors affecting primary care physician decision-making for patients with complex multimorbidity: a qualitative interview study

BACKGROUND

Patients with multiple chronic conditions (multimorbidity) and additional psychosocial complexity are at higher risk of adverse outcomes. Establishing treatment or care plans for these patients must account for their disease interactions, finite self-management abilities, and even conflicting treatment recommendations from clinical practice guidelines. Despite existing insight into how primary care physicians (PCPs) approach care decisions for their patients in general, less is known about how PCPs make care planning decisions for more complex populations particularly within a medical home setting. We therefore sought to describe factors affecting physician decision-making when care planning for complex patients with multimorbidity within the team-based, patient-centered medical home setting in the integrated healthcare system of the U.S. Department of Veterans Affairs, the Veterans Health Administration (VHA).

METHODS

This was a qualitative study involving semi-structured telephone interviews with PCPs working > 40% time in VHA clinics. Interviews were conducted from April to July, 2020. Content was analyzed with deductive and inductive thematic analysis.

RESULTS

23 physicians participated in interviews; most were MDs (n = 21) and worked in hospital-affiliated clinics (n = 14) across all regions of the VHA's national clinic network. We found internal, external, and relationship-based factors, with developed subthemes describing factors affecting decision-making for complex patients with multimorbidity. Physicians described tailoring decisions to individual patients; making decisions in keeping with an underlying internal style or habit; working towards an overarching goal for care; considering impacts from patient access and resources on care plans; deciding within boundaries provided by organizational structures; collaborating on care plans with their care team; and impacts on decisions from their own emotions and relationship with patient.

CONCLUSIONS

PCPs described internal, external, and relationship-based factors that affected their care planning for high-risk and complex patients with multimorbidity in the VHA. Findings offer useful strategies employed by physicians to effectively conduct care planning for complex patients in a medical home setting, such as delegation of follow-up within multidisciplinary care teams, optimizing visit time vs frequency, and deliberate investment in patient-centered relationship building to gain buy-in to care plans.

Ignorance is Not Bliss: The Case for Comprehensive Reproductive Counseling for Women with Chronic Kidney Disease

The bioethics literature has paid little attention to matters of informed reproductive decision-making among women of childbearing age who have chronic kidney disease (CKD), including women who are on dialysis or women who have had a kidney transplant. Women with CKD receive inconsistent and, sometimes, inadequate reproductive counseling, particularly with respect to information about pursuing pregnancy. We identify four factors that might contribute to inadequate and inconsistent reproductive counseling. We argue that women with CKD should receive comprehensive reproductive counseling, including information about the possibility of pursuing pregnancy, and that more rigorous research on pregnancy in women with CKD, including women on dialysis or who have received a kidney transplant, is warranted to improve informed reproductive decision making in this population.

The impact of Health Transformation Plan on natural vaginal delivery and cesarean section frequency in Iran: an interrupted time series analysis

Objective

This study was conducted to evaluate the effect of the Iran’s Health Transformation Plan on the frequency of natural vaginal deliveries (NVDs), cesarean sections (CSs), and total deliveries in the Fars province of Iran.

Results

Average number of total deliveries before and after the reform were 3946 and 3810, respectively (p  =  0.164). The ratio of CS to total deliveries in the first study month was 54%. This rate reached 47% in the last month (p  <  0.01). However, it had much fluctuation trend. The ITSA results showed that in the short-run, the NVD rate increased (β  =  492.79, p  <  0.01), the rate of CS decreased (β  =  − 407.09, p  <  0.01), and total deliveries increased (β  =  85.75, p  <  0.724). However, in the long-run, the NVD (β  =  5.74, p  <  0.423), CS (β  =  10.21, p  <  0.189), and total deliveries (β  =  15.96, p  <  0.256) had no significant changes after the reform. Encouraging the NVD package was influential in the short-run but not in the longrun in Iran. Pricing and supply-side policies could not reduce the rate of non-clinical CS on their own. Therefore, paying attention to demand-side policies and changes in consumer behaviors, such as educating the women at the age of pregnancy about the advantages and disadvantages of CS and NVD and correcting misconceptions, could be helpful.

Elicitation of Rheumatologist Preferences for the Treatment of Patients with Rheumatoid Arthritis After the Failure of a First Conventional Synthetic Disease-Modifying Anti-Rheumatic Agent

Introduction

Rheumatoid arthritis (RA) clinical guidelines do not provide strong recommendations for the choice of disease-modifying anti-rheumatic drugs (DMARD) in patients with an inadequate response to methotrexate (MTX), and only limited evidence is available on factors influencing rheumatologist treatment decisions. We aimed to describe therapeutic preferences after the failure of a first-line strategy of MTX in simulated cases of patients with RA.

Methods

Fictional but realistic case-vignettes (n = 64) of patients with RA and an inadequate response to MTX were developed with a combination of RA-poor prognostic factors and comorbidities. Physicians were presented with eight vignettes and chose the most and least appropriate therapeutic option from the following six options randomly proposed 3 by 3: (1) replacing MTX with another csDMARD; (2) combining MTX with one or more csDMARDs; (3) adding a bDMARD of either TNF inhibitors (TNFi), tocilizumab (TCZ), abatacept (ABA), or rituximab (RTZ). A total of 1605 complete case vignettes were produced and randomly assigned to a representative sample of French rheumatologists. For each vignette, whenever a treatment was preferred, one point was incremented for this treatment; if this treatment was the least desired, one point was removed. Preferences were elicited using a normalized best–worst score.

Results

Two hundred and four French rheumatologists participated in the study with each vignette being assessed 20–28 times for a completion rate of 94%. TNFi was the first-choice strategy (80% of vignettes), except in cases with a history of infection and pulmonary comorbidity, where ABA was the first preference (85%). TCZ came third in 83% of the cases. Other options were never preferred and repeatedly yielded negative scores.

Conclusions

We observed a conservative trend with TNFi as the main therapeutic choice for patients with RA and inadequate response to MTX. Preference for bDMARD-based strategies increased with the number of RA-poor prognosis factors, whereas an increase in the number of comorbidities resulted in an increased preference for ABA. Understanding clinical decision-making will be particularly important as the therapeutic landscape for RA continues to evolve.

From training to implementation: Improving contraceptive practices in South Carolina

OBJECTIVE

Capacity building and training to improve contraceptive care is essential for patient-centered care and reproductive autonomy. This study assessed the feasibility of translating the knowledge and skills gained from contraception trainings into improvements in practice.

STUDY DESIGN

Participants completed surveys following contraceptive care trainings provided to family planning clinic and hospital obstetric providers and staff as a part of the Choose Well contraceptive access initiative in South Carolina. Surveys assessed participants' intent to change their practice post-training and anticipated barriers to implementing change. A mixed-methods approach was utilized including descriptive analysis of Likert scale responses and thematic content analysis to synthesize open-ended, qualitative responses.

RESULTS

Data were collected from 160 contraceptive training sessions provided to 4814 clinical and administrative staff between 2017 and 2019. Post-training surveys were completed by 3464 participants (72%), and of these, 2978 answered questions related to the study outcomes. Most respondents (n = 2390; 80.7%) indicated intent to change their practice and 35.5% (n = 1044) anticipated barriers to implementing intended changes. Across all training categories, organizational factors (time constraints, policies and practices, infrastructure/resources) were the most frequently perceived barrier to improving contraceptive services. Structural factors related to cost for patients were also identified as barriers to IUD and implant provision.

CONCLUSION

The trainings were successful in influencing family planning staff and providers' intent to improve their contraceptive practices, yet some anticipated barriers in translating training into practice. Improvements in organizational and structural policies are critical to realizing the benefits of trainings in advancing quality contraceptive care.

IMPLICATIONS

In addition to training, coordinated efforts to address organizational practices and resources, coupled with system-level policy changes are essential to facilitate the delivery and sustainability of patient-centered contraceptive care.

Understanding Treatment Strategies and Preferences in Nonmetastatic Castration-Resistant Prostate Cancer From the Japanese Physician Perspective

PURPOSE

Sixteen percent (16%) of patients with castration-resistant prostate cancer (CRPC) show no bone metastasis at diagnosis. However, 33% will become metastatic within 2 years. The goal of treatment in patients with nonmetastatic CRPC (nmCRPC), therefore, is to delay symptomatic metastases without undue toxicity. With novel antiandrogen treatments of different strengths and limitations available, physician preferences for nmCRPC treatment in Japan should be understood.

METHODS

A discrete choice experiment was conducted. Physicians chose between two hypothetical treatments in nmCRPC defined by six attributes: risk of fatigue, falls or fracture, cognitive impairment, hypertension, rashes as side effects of treatment, and extension of time until cancer-related pain occurs. Relative preference weights and relative importance were estimated by hierarchical Bayesian logistic regression. Physicians were also asked to make treatment decisions based on four hypothetical patient profiles to understand the most important factors driving decision making.

RESULTS

A total of 151 physicians completed the survey. Extension of time until cancer-related pain occurs was the most important attribute (relative importance, 32.3%; CI, 31.3% to 33.3%). Based on summed preference weights across all attributes, preferences for hypothetical treatment profiles I, II, and III were compared. A hypothetical treatment profile with better safety though shorter extension time was preferred (I: mean [standard deviation] = 1.7 [1.6 to 2.1]) over treatment profiles with lower safety but longer extension time (II: -2.7 [-2.8 to -2.6] and III: -0.2 [-0.3 to -0.1]). Treatment characteristics were more important factors for physicians' decision making than patient characteristics in prescribing treatment.

CONCLUSION

Physicians preferred a treatment with better safety profile, and treatment characteristics were the most important factors for decision making. This might have implications in physicians' decision making for nmCRPC treatment in the future in Japan.

Reschovsky J, Jones DJ, Kimmey L, Furukawa MF, Rich EC. Health system integration with physician specialties varies across markets and system types

OBJECTIVE

To examine system integration with physician specialties across markets and the association between local system characteristics and their patterns of physician integration.

DATA SOURCES

Data come from the AHRQ Compendium of US Health Systems and IQVIA OneKey database.

STUDY DESIGN

We examined the change from 2016 to 2018 in the percentage of physicians in systems, focusing on primary care and the 10 most numerous nonhospital-based specialties across the 382 metropolitan statistical areas (MSAs) in the US. We also categorized systems by ownership, mission, and payment program participation and examined how those characteristics were related to their patterns of physician integration in 2018.

DATA COLLECTION/EXTRACTION METHODS

We examined local healthcare markets (MSAs) and the hospitals and physicians that are part of integrated systems that operate in these markets. We characterized markets by hospital and insurer concentration and systems by type of ownership and by whether they have an academic medical center (AMC), a 340B hospital, or accountable care organization.

PRINCIPAL FINDINGS

Between 2016 and 2018, system participation increased for primary care and the 10 other physician specialties we examined. In 2018, physicians in specialties associated with lucrative hospital services were the most commonly integrated with systems including hematology-oncology (57%), cardiology (55%), and general surgery (44%); however, rates varied substantially across markets. For most specialties, high market concentration by insurers and hospital-systems was associated with lower rates of physician integration. In addition, systems with AMCs and publicly owned systems more commonly affiliated with specialties unrelated to the physicians' potential contribution to hospital revenue, and investor-owned systems demonstrated more limited physician integration.

CONCLUSIONS

Variation in physician integration across markets and system characteristics reflects physician and systems' motivations. These integration strategies are associated with the financial interests of systems and other strategic goals (eg, medical education, and serving low-income populations).

How can we monitor the impact of national health information systems? Results from a scoping review

Background

National health information (HI) systems provide data on population health, the determinants of health and health system performance within countries. The evaluation of these systems has traditionally focused on statistical practices and procedures, and not on data use or reuse for policy and practice. This limits the capacity to assess the impact of HI systems on healthcare provision, management and policy-making. On the other hand, the field of Knowledge Translation (KT) has developed frameworks to guide evidence into practice.

Methods

A scoping review of the KT literature to identify the essential mechanisms and determinants of KT that could help monitor the impact of HI systems.

Results

We examined 79 publications and we identified over 100 different KT frameworks but none of these were focused on HI systems per se. There were specific recommendations on disseminating evidence to stakeholders at the institutional and organizational level, and on sustaining the use of evidence in practice and the broader community setting.

Conclusions

We developed a new model, the HI-Impact framework, in which four domains are essential for mapping the impact of national HI systems: (i) HI Evidence Quality, (ii) HI System Responsiveness, (iii) Stakeholder Engagement and (iv) Knowledge Integration. A comprehensive impact assessment of HI systems requires addressing the use of HI in public health decision-making, health service delivery and in other sectors which might have not been considered previously. Monitoring Stakeholder Engagement and Knowledge Integration certifies that the use of HI in all policies is an explicit point of assessment.

Variations in use of childbirth interventions in 13 high-income countries: A multinational cross-sectional study

BACKGROUND

Variations in intervention rates, without subsequent reductions in adverse outcomes, can indicate overuse. We studied variations in and associations between commonly used childbirth interventions and adverse outcomes, adjusted for population characteristics.

METHODS AND FINDINGS

In this multinational cross-sectional study, existing data on 4,729,307 singleton births at ≥37 weeks in 2013 from Finland, Sweden, Norway, Denmark, Iceland, Ireland, England, the Netherlands, Belgium, Germany (Hesse), Malta, the United States, and Chile were used to describe variations in childbirth interventions and outcomes. Numbers of births ranged from 3,987 for Iceland to 3,500,397 for the USA. Crude data were analysed in the Netherlands, or analysed data were shared with the principal investigator. Strict variable definitions were used and information on data quality was collected. Intervention rates were described for each country and stratified by parity. Uni- and multivariable analyses were performed, adjusted for population characteristics, and associations between rates of interventions, population characteristics, and outcomes were assessed using Spearman's rank correlation coefficients. Considerable intercountry variations were found for all interventions, despite adjustments for population characteristics. Adjustments for ethnicity and body mass index changed odds ratios for augmentation of labour and episiotomy. Largest variations were found for augmentation of labour, pain relief, episiotomy, instrumental birth, and cesarean section (CS). Percentages of births at ≥42 weeks varied from 0.1% to 6.7%. Rates among nulliparous versus multiparous women varied from 56% to 80% versus 51% to 82% for spontaneous onset of labour; 14% to 36% versus 8% to 28% for induction of labour; 3% to 13% versus 7% to 26% for prelabour CS; 16% to 48% versus 12% to 50% for overall CS; 22% to 71% versus 7% to 38% for augmentation of labour; 50% to 93% versus 25% to 86% for any intrapartum pain relief, 19% to 83% versus 10% to 64% for epidural anaesthesia; 6% to 68% versus 2% to 30% for episiotomy in vaginal births; 3% to 30% versus 1% to 7% for instrumental vaginal births; and 42% to 70% versus 50% to 84% for spontaneous vaginal births. Countries with higher rates of births at ≥42 weeks had higher rates of births with a spontaneous onset (rho = 0.82 for nulliparous/rho = 0.83 for multiparous women) and instrumental (rho = 0.67) and spontaneous (rho = 0.66) vaginal births among multiparous women and lower rates of induction of labour (rho = -0.71/-0.66), prelabour CS (rho = -0.61/-0.65), overall CS (rho = -0.61/-0.67), and episiotomy (multiparous: rho = -0.67). Variation in CS rates was mainly due to prelabour CS (rho = 0.96). Countries with higher rates of births with a spontaneous onset had lower rates of emergency CS (nulliparous: rho = -0.62) and higher rates of spontaneous vaginal births (multiparous: rho = 0.70). Prelabour and emergency CS were positively correlated (nulliparous: rho = 0.74). Higher rates of obstetric anal sphincter injury following vaginal birth were found in countries with higher rates of spontaneous birth (nulliparous: rho = 0.65). In countries with higher rates of epidural anaesthesia (nulliparous) and spontaneous births (multiparous), higher rates of Apgar score < 7 were found (rhos = 0.64). No statistically significant variation was found for perinatal mortality. Main limitations were varying quality of data and missing information.

CONCLUSIONS

Considerable intercountry variations were found for all interventions, even after adjusting for population characteristics, indicating overuse of interventions in some countries. Multivariable analyses are essential when comparing intercountry rates. Implementation of evidence-based guidelines is crucial in optimising intervention use and improving quality of maternity care worldwide.

Adherence to Current Lipid Guidelines by Physicians in Kuwait

BACKGROUND

Alarmingly high rates of dyslipidemia have been found in the Gulf region in patients presenting with acute coronary syndrome, with the highest being found in Kuwait (37%). Therefore, it is of utmost importance to treat dyslipidemia promptly and effectively. In an effort to understand the practices of local physicians, the use of evidence-based medicine, and adherence to lipid treatment guidelines, the objective of this study was to survey and assess the current standards of care.

METHODS

A survey questionnaire, designed to assess physicians' attitudes and practice towards lipid guidelines, was completed by 279 participants and returned between October 2015 and June 2016. Statistical analysis was done using SPSS.

RESULTS

Over 90% of physicians claimed to use lipid guidelines, with the majority rating themselves as knowledgeable. Younger physicians were found to be less knowledgeable and consequently used guidelines less frequently. The most important factor influencing clinical decision-making was the availability of clinical guidelines. The majority (72.4%) of physicians identified time limitation as a key barrier. The most commonly selected lipid guideline in daily practice was a guideline on the treatment of blood cholesterol published by the American College of Cardiology/American Heart Association in 2013. The most common risk assessment tool used was the Framingham risk score.

CONCLUSIONS

Multiple interventions to improve guideline adherence are proposed in this study. We have taken into account the barriers to adherence, i.e., attitude, behavior, and (most importantly) knowledge, all 3 of which were reaffirmed in our investigation in Kuwait.

Incidence of thyroid cancer in Puerto Rico and the US by racial/ethnic group, 2011-2015

BACKGROUND

Puerto Rico has the highest incidence rate of thyroid cancer (TC) in the Americas and the third highest rate worldwide. The purpose of this study was to compare the burden of TC between the population of PR and United States (US) non-Hispanic Whites (NHW), non-Hispanic Blacks (NHB), and US Hispanics (USH) during the period 2011-2015.

METHODS

TC data for the period 2011-2015 was obtained from the Puerto Rico Central Cancer Registry (PRCCR) and the Surveillance Epidemiology and Ends Results Program (SEER) 18 Registries Research Data. TC was categorized in: papillary carcinoma (PTC), and other TC histologic types. Data was analyzed by sex, age groups, and histologic type. Racial/ethnic differences by sex, age, and histologic types were assessed using the Standardized Rate Ratio (SRR) and its 95% CI.

RESULTS

During the period 2011-2015 there were 5175 and 65,528 cases of TC diagnosed in PR and the US, respectively. The overall age-adjusted incidence rate of PTC was almost two-fold higher in PR than in the US (25.8/100,000 vs. 12.9/100,000). Among PR women, the incidence rate of PTC was 40.0/100,000 compared to 19.4/100,000 in US. PR women had 83% increased risk of being diagnosed with PTC than NHW women, a 2.25-fold increased risk than USH, and 3.45-fold increased risk than NHB women. For men, PR had 34% increased risk of being diagnosed with PTC than NHW men, 2.2-fold increased risk than USH men, and 3.2-fold higher risk than in NHB men.

CONCLUSION

Further research is needed to understand this disparity in the island. This research should address the extent of overdiagnosis in PR, the role of health insurance status and insurance type, characteristics of the healthcare delivery system as well as the role of patient and environmental factors.

Characteristics of Emergency Department Visits and Select Predictors of Hospitalization for Adults With Newly Diagnosed Cancer in a Safety-Net Health System

PURPOSE

There is little description of emergency department (ED) visits and subsequent hospitalizations among a safety-net cancer population. We characterized patterns of ED visits and explored nonclinical predictors of subsequent hospitalization, including time of ED arrival.

PATIENTS AND METHODS

This was a retrospective cohort study of patients with cancer (excluding leukemia and nonmelanoma skin cancer) between 2012 and 2016 at a large county urban safety-net health system. We identified ED visits occurring within 180 days after a cancer diagnosis, along with subsequent hospitalizations (observation stay or inpatient admission). We used mixed-effects multivariable logistic regression to model hospitalization at ED disposition, accounting for variability across patients and emergency physicians.

RESULTS

The 9,050 adults with cancer were 77.2% nonwhite and 55.0% female. Nearly one-quarter (24.7%) of patients had advanced-stage cancer at diagnosis, and 9.7% died within 180 days of diagnosis. These patients accrued 11,282 ED visits within 180 days of diagnosis. Most patients had at least one ED visit (57.7%); half (49.9%) occurred during business hours (Monday through Friday, 8:00 am to 4:59 pm), and half (50.4%) resulted in hospitalization. More than half (57.5%) of ED visits were for complaints that included: pain/headache, nausea/vomiting/dehydration, fever, swelling, shortness of breath/cough, and medication refill. Patients were most often discharged home when they arrived between 8:00 am and 11:59 am (adjusted odds ratio for hospitalization, 0.69; 95% CI, 0.56 to 0.84).

CONCLUSION

ED visits are common among safety-net patients with newly diagnosed cancer, and hospitalizations may be influenced by nonclinical factors. The majority of ED visits made by adults with newly diagnosed cancer in a safety-net health system could potentially be routed to an alternate site of care, such as a cancer urgent care clinic.

Barriers to Minimizing Respiratory Viral Testing in Bronchiolitis: Physician Perceptions on Testing Practices

OBJECTIVES

To assess pediatric providers' perceptions on viral testing and to determine barriers to minimizing respiratory viral testing (RVT) in bronchiolitis.

METHODS

A single-center, cross-sectional study was conducted and included 6 focus group discussions with pediatric providers. Questions were focused on identifying factors associated with obtaining RVT. Focus group discussions were transcribed verbatim and coded for emergent themes.

RESULTS

Clinicians report that they themselves do not typically obtain RVT in otherwise healthy patients with bronchiolitis. The most commonly cited reasons for not obtaining RVT is that it does not aid medical decision-making and that it is used as an educational opportunity for trainees. However, clinicians tend to obtain RVT when they are directed by another clinician, when they desire reassurance, when RVT is perceived as "doing something," and when there are knowledge gaps on institutional cohorting policies.

CONCLUSIONS

Clinician medical decision-making is influenced by multiple internal and external factors. Intended behaviors do not always correlate with actual actions because of these influences. Developing interventions in which some of these factors are addressed may help reduce unnecessary RVT among healthy patients with bronchiolitis and could be considered for broader application beyond this patient population.

Linking physician attitudes to their breast cancer screening practices: A survey of US primary care providers and gynecologists

Despite changes to breast cancer screening guidelines intended to decrease screening in younger and older women, mammography rates remain high. We investigated physician attitudes towards screening younger and older women. Surveys were mailed to US primary care providers and gynecologists between May and September 2016 (871/1665, 52.3% adjusted response rate). We assessed physician (1) attitudes towards screening younger (45-49years) and older (75+ years) women and (2) recommendations for routine mammography. We used exploratory factor analysis to identify underlying themes among physician attitudes and created measures standardized to a 5-point scale. Using multivariable logistic regression models, we examined associations between physician attitudes and screening recommendations. Attitudes identified with factor analysis included: potential regret, expectations, and discordant guidelines (referred to as potential regret), patient-related hazards due to screening, physician limitations and uncertainty, and concerns about rationing care. Gynecologists had higher levels of potential regret compared to internists. In adjusted analyses, physicians with increasing potential regret (1-point increment on 5-point scale) had higher odds of recommending mammography to younger (OR 8.68; 95% CI 5.25-14.36) and older women (OR 4.62; 95% CI 3.50-6.11). Increasing concern for patient-related hazards was associated with decreased odds of recommending screening to older women (OR 0.68; 95% CI 0.56-0.83). Physicians were more motivated by potential regret in recommending screening for younger and older women than by concerns for patient-related hazards in screening. Addressing physicians' most salient concerns, such as fear of missing cancer diagnoses and malpractice, may present an important opportunity to improving delivery of guideline-concordant cancer screening.

Variables That Influence US Midwife and Physician Management of the Third Stage of Labor

INTRODUCTION

Midwives and physicians incorporate their knowledge, experiences, and other variables in making clinical decisions. Variations in the management of the third stage of labor may be a result of variables that influence providers' decision making. The purpose of this study was to describe variables that influence US midwives' and physicians' management of the third stage of labor.

METHODS

A randomly selected national sample of certified nurse-midwives and certified midwives, certified professional midwives, obstetricians, and family physicians was surveyed about the extent to which maternal characteristics, maternal history, and current birth characteristics influence their third-stage management. The extent of influence was defined in terms of always to never altering management. Descriptive summaries, group comparisons, and partial correlations were used to determine differences in influences between midwives and physicians. One free-text question was analyzed using qualitative methods.

RESULTS

A total of 1243 clinicians responded. There was considerable variability in the response patterns in that the same variable was reported to always alter management during the third stage of labor for some participants yet did not influence the management practices of others at all. Differences between responses from midwives and physicians were explored as a possible explanation for some of the variability. In response to the free-text inquiry about variables that most influenced changes in participants' usual management of the third stage, the participants most often included active bleeding, current recommendations or guidelines, and maternal or family preferences.

DISCUSSION

This study identifies variables reported as influencing clinical decision making during the third stage of labor. Therefore, these variables are important to consider when evaluating interventions and outcomes related to management of the third stage of labor and any attempts to design new interventions. The findings are descriptive of practice; they are not intended to guide changes in practice.

Practice variation and practice guidelines: Attitudes of generalist and specialist physicians, nurse practitioners, and physician assistants

Objective

To understand clinicians' beliefs about practice variation and how variation might be reduced.

Methods

We surveyed board-certified physicians (N = 178), nurse practitioners (N = 60), and physician assistants (N = 12) at an academic medical center and two community clinics, representing family medicine, general internal medicine, and cardiology, from February—April 2016. The Internet-based questionnaire ascertained clinicians' beliefs regarding practice variation, clinical practice guidelines, and costs.

Results

Respondents agreed that practice variation should be reduced (mean [SD] 4.5 [1.1]; 1 = strongly disagree, 6 = strongly agree), but agreed less strongly (4.1 [1.0]) that it can realistically be reduced. They moderately agreed that variation is justified by situational differences (3.9 [1.2]). They strongly agreed (5.2 [0.8]) that clinicians should help reduce healthcare costs, but agreed less strongly (4.4 [1.1]) that reducing practice variation would reduce costs. Nearly all respondents (234/249 [94%]) currently depend on practice guidelines. Clinicians rated differences in clinician style and experience as most influencing practice variation, and inaccessibility of guidelines as least influential. Time to apply standards, and patient decision aids, were rated most likely to help standardize practice. Nurse practitioners and physicians assistants (vs physicians) and less experienced (vs senior) clinicians rated more favorably several factors that might help to standardize practice. Differences by specialty and academic vs community practice were small.

Conclusions

Clinicians believe that practice variation should be reduced, but are less certain that this can be achieved. Accessibility of guidelines is not a significant barrier to practice standardization, whereas more time to apply standards is viewed as potentially helpful.

Time to establish comprehensive long-term monitoring of Australian medical graduates?

We believe that the well being of our medical students (and medical staff throughout the continuum of practice) matters too much not to ask, ‘How do they feel?’ Society, and students themselves, have invested too much in their education not to query ‘How well are they performing in the workplace?’. Our accountability to the community demands we ask, ‘How are their patients going?’ This article presents a schema for building long-term monitoring in Australia, using linked and reliable data, that will enable these questions to be answered. Although the answers will be of interest to many, medical schools will then be well placed to alter their programs and processes based on these three domains of graduate well being, workplace performance and patient outcomes.

Derivation and validation of the Personal Support Algorithm: an evidence-based framework to inform allocation of personal support services in home and community care

Background

Personal support services enable many individuals to stay in their homes, but there are no standard ways to classify need for functional support in home and community care settings. The goal of this project was to develop an evidence-based clinical tool to inform service planning while allowing for flexibility in care coordinator judgment in response to patient and family circumstances.

Methods

The sample included 128,169 Ontario home care patients assessed in 2013 and 25,800 Ontario community support clients assessed between 2014 and 2016. Independent variables were drawn from the Resident Assessment Instrument-Home Care and interRAI Community Health Assessment that are standardised, comprehensive, and fully compatible clinical assessments. Clinical expertise and regression analyses identified candidate variables that were entered into decision tree models. The primary dependent variable was the weekly hours of personal support calculated based on the record of billed services.

Results

The Personal Support Algorithm classified need for personal support into six groups with a 32-fold difference in average billed hours of personal support services between the highest and lowest group. The algorithm explained 30.8% of the variability in billed personal support services. Care coordinators and managers reported that the guidelines based on the algorithm classification were consistent with their clinical judgment and current practice.

Conclusions

The Personal Support Algorithm provides a structured yet flexible decision-support framework that may facilitate a more transparent and equitable approach to the allocation of personal support services.

Clinician-Level Predictors for Ordering Low-Value Imaging

IMPORTANCE

Clinicians who order unnecessary radiographic imaging may cause financial harm to patients who have increasing levels of cost sharing. Clinician predictors of low-value imaging are largely unknown.

OBJECTIVE

To characterize clinician predictors of low-value imaging for acute uncomplicated back pain and headache, including clinicians who saw both conditions.

DESIGN, SETTING, AND PARTICIPANTS

Multivariate logistic regression modeling of imaging rates after acute uncomplicated back pain and headache visits as indicated by January 2010 to December 2014 commercial insurance claims and demographic data from a large US health insurer. Participants included 100 977 clinicians (primary care physicians, specialist physicians, and chiropractors).

MAIN OUTCOMES AND MEASURES

Imaging after acute uncomplicated back pain and headache visits was recorded. We identified whether the clinician's prior patient received imaging, whether the clinician was an owner of imaging equipment, and the varying impact by clinician specialty. We then used high rates of low-value back imaging as a predictor for low-value headache imaging.

RESULTS

Clinicians conducted 1 007 392 visits for 878 720 adults ages 18 to 64 years with acute uncomplicated back pain; 52 876 primary care physicians conducted visits for 492 805 adults ages 18 to 64 years with acute uncomplicated headache; 34 190 primary care clinicians conducted 405 721 visits for 344 991 adults ages 18 to 64 years with headache and had also conducted at least 4 visits from patients with back pain. If a primary care physician's prior patient received low-value back imaging, the patient had 1.81 higher odds of low-value imaging (95% CI, 1.77-1.85). This practice effect was larger for chiropractors (odds ratio [OR], 2.80; 95% CI, 2.74-2.86) and specialists (OR, 2.98; 95% CI, 2.88-3.07). For headache, a prior low-value head image predicted 2.00 higher odds of a subsequent head imaging order (95% CI, 1.95-2.06). Clinician ownership of imaging equipment was a consistent independent predictor of low-value imaging (OR, 1.65-7.76) across clinician type and imaging scenario. Primary care physicians with the highest rates of low-value back imaging also had 1.53 (95% CI, 1.45-1.61) higher odds of ordering low-value headache imaging.

CONCLUSIONS AND RELEVANCE

Clinician characteristics such as ordering low-value imaging on a prior patient, high rates of low-value imaging in another clinical scenario, and ownership of imaging equipment are strong predictors of low-value back and headache imaging. Findings should inform policies that target potentially unnecessary and financially burdensome care.

US internists' awareness and use of overtreatment guidelines: a national survey

OBJECTIVES

To assess physician views and perceived adoption of overtreatment guidelines and measure whether adoption of these guidelines influenced the recommendation of a targeted service.

STUDY DESIGN

A cross-sectional survey mailed from July 2014 to January 2015 to 902 internists who completed residency between 2003 and 2013, randomly selected from the American Medical Association Masterfile.

METHODS

Poisson regression was used to model the rate of recommending a targeted service included in the guidelines, based on the level of guideline adoption.

RESULTS

A total of 456 physicians responded (51% response rate). Most expressed familiarity with overtreatment guidelines (88.5%), a comfort level with discussing these guidelines with patients (79.9%), and described overtreatment guidelines as a useful tool in their practice (81.6%). Physicians in the highest tertile of guideline adoption reported double-digit rates of recommending antibiotics for sinusitis (29.7%), mammogram at end of life (16.5%), and electrocardiogram testing for asymptomatic patients (11.0%). Physicians in the bottom tertile of guideline adoption reported lower rates of recommending x rays (-12.0%; 95% confidence interval [CI], -19.4% to -4.5%; P = .002), magnetic resonance imaging for lower back pain (-4.8%; 95% CI, -8.1% to -1.5%; P = .004), and cardiac testing for asymptomatic patients (-10.2%; 95% CI, -18.9% to -1.5%; P = .02).

CONCLUSIONS

US internal medicine physicians who completed residency between 2003 and 2013 reported high levels of adoption of overtreatment guidelines. Physicians who reported the highest levels of guideline adoption reported recommending services targeted by these guidelines in their practice.

Prescription of oral short-acting beta 2-agonist for asthma in non-resource poor settings: A national study in Malaysia

OBJECTIVE

Use of oral short-acting beta 2-agonist (SABA) persists in non-resource poor countries despite concerns for its lower efficacy and safety. Utilisation and reasons for such use is needed to support the effort to discourage the use of oral SABA in asthma. This study examined the frequency of oral short-acting Beta 2-agonist (SABA) usage in the management of asthma in primary care and determined correlates of its usage.

METHODS

Data used were from the 2014 National Medical Care Survey in Malaysia, a nationally representative survey of primary care encounters (weighted n = 325818). Using methods of analysis of data for complex surveys, we determined the frequency of asthma diagnosis in primary care and the rate of asthma medication prescription, which includes oral SABA. Multivariate logistic regression models were built to assess associations with the prescription of oral SABA.

RESULTS

A weighted estimate of 9241 encounters presented to primary care with asthma in 2014. The mean age of the patients was 39.1 years. The rate of oral SABA, oral steroids, inhaled SABA and inhaled corticosteroids prescriptions were 33, 33, 50 and 23 per 100 asthma encounters, respectively. It was most commonly used in patients with the age ranged between 20 to less than 40 years. Logistic regression models showed that there was a higher odds of oral SABA usage in the presence of respiratory infection, prescription of oral corticosteroids and in the private sector.

CONCLUSION

Oral SABA use in asthma is found to be common in a non- resource poor setting and its use could be attributed to a preference for oral medicines along undesirable clinical practices within a fragmented health system.

Gender Differences in Physician Service Provision Using Medicare Claims Data

OBJECTIVE

To determine differences in the provision of Medicare services based on physician gender in the United States.

PATIENTS AND METHODS

Participants included all 2013 Medicare fee-for-service physicians and their patients, a population that is predominantly older than 65 years. The 2013 Medicare Provider Utilization and Payment Data for services rendered between January 1, 2013, and December 31, 2013, were combined with the 2015 Physician Compare National Downloadable files and 2015 Berenson-Eggers Type of Service classification files. Total fee-for-service Medicare payments and Healthcare Common Procedure Coding System procedure codes for all fee-for-service beneficiaries were aggregated according to physician gender, specialty, years since medical school graduation, and type of service classifications.

RESULTS

Excluding drug reimbursement, the mean total Medicare payments per female physician, compared with those for male physicians, were 41% in surgical specialties, 72% in hospital-based specialties, and 55% across all specialties (P<.001). The mean overall number of unique beneficiary visits per female physician was 59% of that for male physicians (P<.001). By using the Berenson-Eggers Type of Service classification, procedures and other services by female physicians were of 54% lower overall average intensity (allowed payments/number of unique patients) compared with those of male physicians. These differences persisted irrespective of years since medical school graduation (P<.001).

CONCLUSION

Female physicians had smaller average total Medicare payments and fewer unique beneficiary visits than male physicians in the care of fee-for-service Medicare beneficiaries in 2013. The differences persisted across specialty types and years in practice. These data can identify variation but cannot determine causation or explain the reasons behind gender differences. These findings suggest, but do not prove, that female physician Medicare payments are lower due to different practice patterns, consisting of fewer patients cared for and lower intensity of care.

A Practical Framework for Understanding and Reducing Medical Overuse: Conceptualizing Overuse Through the Patient-Clinician Interaction

Overuse of medical services is an increasingly recognized driver of poor-quality care and high cost. A practical framework is needed to guide clinical decisions and facilitate concrete actions that can reduce overuse and improve care. We used an iterative, expert-informed, evidence-based process to develop a framework for conceptualizing interventions to reduce medical overuse. Given the complexity of defining and identifying overused care in nuanced clinical situations and the need to define care appropriateness in the context of an individual patient, this framework conceptualizes the patient-clinician interaction as the nexus of decisions regarding inappropriate care. This interaction is influenced by other utilization drivers, including healthcare system factors, the practice environment, the culture of professional medicine, the culture of healthcare consumption, and individual patient and clinician factors. The variable strength of the evidence supporting these domains highlights important areas for further investigation. Journal of Hospital Medicine 2017;12:346-351.

Barriers to evidence-based physician decision-making at the point of care: a narrative literature review

We conduct a narrative literature review using four real-world cases of clinical decisions to show how barriers to the use of evidence-based medicine affect physician decision-making at the point of care, and where adjustments could be made in the healthcare system to address these barriers. Our four cases constitute decisions typical of the types physicians make on a regular basis: diagnostic testing, initial treatment and treatment monitoring. To shed light on opportunities to improve patient care while reducing costs, we focus on barriers that could be addressed through changes to policy and/or practice at a particular level of the healthcare system. We conclude by relating our findings to the passage of the Medicare Access and Children's Health Insurance Program Reauthorization Act in April 2015.

Barriers to and Facilitators of Evidence-Based Decision Making at the Point of Care: Implications for Delivery Systems, Payers, and Policy Makers

Introduction: Physicians vary widely in how they treat some health conditions, despite strong evidence favoring certain treatments over others. We examined physicians’ perspectives on factors that support or hinder evidence-based decisions and the implications for delivery systems, payers, and policymakers. Methods: We used Choosing Wisely^® recommendations to create four clinical vignettes for common types of decisions. We conducted semi-structured interviews with 36 specialists to identify factors that support or hinder evidence-based decisions. We examined these factors using a conceptual framework that includes six levels: patients, physicians, practice sites, organizations, networks and hospital affiliations, and the local market. In this model, population characteristics and payer and regulatory factors interact to influence decisions. Results: Patient openness to behavior modification and expectations, facilitated and hindered physicians in making evidence-based recommendations. Physicians’ communication skills were the most commonly mentioned facilitator. Practice site, organization, and hospital system barriers included measures of emergency department throughput, the order in which test options are listed in electronic health records (EHR), lack of relevant decision support in EHRs, and payment incentives that maximize billing and encourage procedures rather than medical management or counseling patients on behavior change. Factors from different levels interacted to undermine evidence-based care. Most physicians received billing feedback, but quality metrics on evidence-based service use were nonexistent for the four decisions in this study. Conclusions and Implications: Additional research and quality improvement may help to modify delivery systems to overcome barriers at multiple levels. Enhancing provider communication skills, improving decision support in EHRs, modifying workflows, and refining the design and interpretation of some quality metrics would help, particularly if combined with concurrent payment reform to realign financial incentives across stakeholders.

Gender differences in mood stabilizer medications prescribed to Veterans with serious mental illness

BACKGROUND

Mood stabilizer medications (MSMs) can induce significant weight gain and other metabolic side effects. Research suggests that women are more susceptible to psychotropic medication-induced metabolic side effects than men. We examined gender differences in the likelihood of receiving an MSM with a lower liability for weight gain using data from the U.S. Department of Veterans Affairs (VA) healthcare system.

METHODS

We identified 3823 VA patients with a schizophrenia or bipolar disorder diagnosis who initiated treatment with a MSM between 10/2006 and 9/2011. We used multivariable logistic regression analysis to examine gender differences in the likelihood of incident prescription of MSMs with low versus medium/high metabolic risk, adjusting for fiscal year of prescribing and demographic, mental health, and physical health characteristics.

RESULTS

Overall, 47% of women were prescribed a low metabolic risk MSM compared to 26% of men (p<0.0001). In multivariable analysis, women were 2.19 times as likely as men to be prescribed a low metabolic risk MSM (95% CI: 1.84-2.60, p<0.0001). Several demographic and clinical covariates were also independently related to prescribing of MSMs by level of metabolic risk.

LIMITATIONS

This study used retrospective administrative data collected from a VA healthcare system database, which does not allow us to understand the context in which MSM treatment decisions were made.

CONCLUSIONS

Prescribing choices for MSMs by VA mental health prescribers and female Veterans may reflect a growing awareness of the potential adverse health consequences of these treatments in women.

Measuring Changes in the Economics of Medical Practice

For the latter third of the twentieth century, researchers have estimated production and cost functions for physician practices. Today, those attempting to measure the inputs and outputs of physician practice must account for many recent changes in models of care delivery. In this paper, we review practice inputs and outputs as typically described in research on the economics of medical practice, and consider the implications of the changing organization of medical practice and nature of physician work. This evolving environment has created conceptual challenges in what are the appropriate measures of output from physician work, as well as what inputs should be measured. Likewise, the increasing complexity of physician practice organizations has introduced challenges to finding the appropriate data sources for measuring these constructs. Both these conceptual and data challenges pose measurement issues that must be overcome to study the economics of modern medical practice. Despite these challenges, there are several promising initiatives involving data sharing at the organizational level that could provide a starting point for developing the needed new data sources and metrics for physician inputs and outputs. However, additional efforts will be required to establish data collection approaches and measurements applicable to smaller and single specialty practices. Overcoming these measurement and data challenges will be key to supporting policy-relevant research on the changing economics of medical practice.
