Abstract Background Alzheimer’s disease (AD) is a major global health crisis in need of more effective therapies. However, difficult choices to optimize value-based care will need to be made. While identifying preferred therapeutic attributes of new AD therapies is necessary, few studies have explored how preferences may vary between the stakeholders. In this study, the trade-offs among key attributes of amyloid plaque-lowering therapies for AD were assessed using a discrete choice experiment (DCE) and compared between caregivers and neurologists. Methods An initial pilot study was conducted to identify the potentially relevant features of a new therapy. The DCE evaluated seven drug attributes: clinical effects in terms of delay in AD progression over the standard of care (SOC), variation in clinical effects, biomarker response (achieving amyloid plaque clearance on PET scan), amyloid-related imaging abnormalities-edema (ARIA-E), duration of therapy, need for treatment titration as well as route, and frequency of drug administration. Respondents were then randomly presented with 12 choice sets of treatment options and asked to select their preferred option in each choice set. Hierarchical Bayesian regression modeling was used to estimate weighted preference attributes, which were presented as mean partial utility scores (pUS), with higher scores suggesting an increased preference. Results Both caregivers (n = 137) and neurologists (n = 161) considered clinical effects (mean pUS = 0.47 and 0.82) and a 5% incremental in ARIA-E (mean pUS = − 0.26 and − 0.52) to be highly impactful determinants of therapeutic choice. In contrast, variation in clinical effects (mean pUS = 0.12 and 0.14) and treatment duration (mean pUS = − 0.02 and − 0.13) were the least important characteristics of any new treatment. Neurologists’ also indicated that subcutaneous drug delivery (mean pUS = 0.42 vs. 0.07) and administration every 4 weeks (mean pUS = 1.0 vs. 0.20) are highly desirable therapeutic features. Respondents were willing to accept up to a 9% increment in ARIA-E for one additional year of delayed progression. Conclusions Caregivers and neurologists considered incremental clinical benefit over SOC and safety to be highly desirable qualities for a new drug that could clear amyloid plaques and delay clinical progression and indicated a willingness to accept incremental ARIA-E to achieve additional clinical benefits.

Background: The endothelin receptor antagonist (ERA) clazosentan is being investigated for the medical prevention of cerebral vasospasm and associated complications, such as delayed cerebral ischemia (DCI), after aneurysmal subarachnoid hemorrhage (aSAH). This study quantified how clinicians weigh the benefits and risks of ERAs for DCI prevention to better understand their treatment needs and expectations. Methods: An online choice experiment was conducted to elicit preferences of neurologists, intensivists, and neurosurgeons treating aSAH in the US and UK for the use of ERAs. The design of the choice experiment was informed by a feasibility assessment (N = 100), one-on-one interviews with clinicians (N = 10), a qualitative pilot (N = 13), and a quantitative pilot (N = 50). Selected treatment attributes included in the choice experiment were: one benefit (likelihood of DCI); and three risks (lung complications, hypotension, and anemia). In the choice experiment, clinicians repeatedly chose best and worst treatment options based on a scenario of a patient being treated in the ICU after aneurism repair. A correlated mixed logit model determined the relative attribute importance (RAI) and associated highest density interval (HDI) as well as acceptable benefit-risk trade-offs. Results: The final choice experiment was completed by 350 clinicians (116 neurologists, 129 intensivists/intensive care clinicians, and 105 neurosurgeons; mean age, 47.4 years). Reducing the likelihood of DCI (RAI = 56.5% [HDI, 53.6-59.5%]) had the largest impact on clinicians' treatment choices, followed by avoiding the risks of lung complications (RAI = 29.6% [HDI, 27.1-32.3%]), hypotension (RAI = 9.2% [HDI, 7.5-10.8%]), and anemia (RAI = 4.7% [HDI, 3.7-5.8%]). Clinicians expected the likelihood of DCI to decrease by ≥8.1% for a 20% increase in the risk of lung complications, ≥2.4% for a 20% increase in the risk of hypotension, and ≥1.2% for a 20% increase in the risk of anemia. Conclusions: Clinicians were willing to accept certain increased risks of adverse events for a reduced risk of DCI after aSAH. The likelihood of DCI occurring after aSAH can therefore be considered a clinically relevant endpoint in aSAH treatment development. Thus, evaluations of ERAs might focus on whether improvements (i.e., reductions) in the likelihood of DCI justify the risks of adverse events. [ABSTRACT FROM AUTHOR]

Introduction: Alzheimer's disease (AD) is a chronic neurodegenerative disorder associated with a high burden of illness. New therapies under development include agents that target amyloid-beta (Aβ), a key component in AD pathogenesis. Understanding the decision-making process for new AD drugs would help determine if such therapies should be adopted by society. Multicriteria decision analysis (MCDA) was applied to three key stakeholder groups to assess treatment alternatives for AD based on a multitude of decision trade-offs covering main components of care. Methods: AD caregivers (n = 117), neurologists (n = 90), and payors (n = 90) from the USA received an online survey. The decision problem was broken down into four decision criterion and 12 subcriteria for two treatment scenarios: an Aβ-targeted therapy vs. the standard of care (SOC). Respondents were asked to indicate how much they preferred one option over another on a scale from 1 (equal preference) to 9 (high preference) based on each criterion and subcriterion. The decision criteria and subcriteria were weighted and presented as partial utility scores (pUS), with higher scores suggesting an increased preference for that decision-making component. Results: Caregivers and payors applied the highest value to need for intervention (mean pUS = 0.303 and 0.259) and clinical outcomes (mean pUS = 0.286 and 0.377). In contrast, neurologists placed the highest value on clinical outcomes and types of benefits (mean pUS = 0.436 and 0.248). When decision subcriteria were examined, efficacy (mean pUS = 0.115, 0.219, and 0.166) and the type of patient benefits (mean pUS = 0.135, 0.178, and 0.126) were among the most valued by caregivers, neurologists, and payors. Conclusion: All groups placed the highest value on drug efficacy and types of benefit derived by patients. In contrast, cost implications were among the least important aspects in their decision-making. [ABSTRACT FROM AUTHOR]

In China, Traditional Chinese Medicine (TCM) is used widely in the treatment of cancer.Objective: To estimate TCM treatment preferences and SDM mode of physicians in China.Methods: This study was conducted among physicians (n=185) from nine tertiary hospitals in China by discrete-choice experiment (DCE) survey and Shared Decision-Making Questionnaire-physician version (SDM-Q-Doc) survey. The DCE was developed with the inclusion of the most relevant attributes at appropriate levels for the TCM treatment of lung cancer. The empirical data analyses of physicians were performed using mixed logit models. Additionally, subgroup analysis was conducted.Results: In total, 185 respondents completed the questionnaire. All attributes were statistically significant except out-of-pocket costs. Physicians showed the strongest preferences for increasing disease control rate, relieving nausea and vomiting, and reducing the risk of side effects. Most of the physicians (78.38%) self-reported a high willingness to use SDM during the decision-making process. The physicians with a higher SDM-Q-Doc score had more preference for improving all three attributes than those with a lower score. Little variation was found in preferences among the physicians with other sociodemographic characteristics.Conclusion: In China, physicians considered disease control rate as the most essential attribute in the TCM treatment of lung cancer. The physicians in China mainly preferred SDM, and the preference was different according to SDM mode when involving the TCM therapy for patients with lung cancer. The study findings could inform future TCM therapy for lung cancer and promote SDM.Keywords: lung cancer, physician preference, discrete-choice experiment, shared decision-making, Traditional Chinese Medicine, China

Background Evidence of the ethical appropriateness and clinical benefits of shared decision-making (SDM) are accumulating. This study aimed to not only identify physicians’ perspectives on SDM, and practices related to end-of-life care in particular, but also to gauge the effect of SDM education on physicians in Korea. Methods A 14-item questionnaire survey using a modified Delphi process was delivered to nephrologists and internal medicine trainees at 17 university hospitals. Results A total of 309 physicians completed the survey. Although respondents reported that 69.9% of their practical decisions were made using SDM, 59.9% reported that it is not being applied appropriately. Only 12.3% of respondents had received education on SDM as part of their training. The main obstacles to appropriate SDM were identified as lack of time (46.0%), educational materials and tools (29.4%), and education on SDM (24.3%). Although only a few respondents had received training on SDM, the proportion of those who thought they were using SDM appropriately in actual practice was high; the proportion of those who chose lack of time and education as factors that hindered the proper application of SDM was low. Conclusion The majority of respondents believed that SDM was not being implemented properly in Korea, despite its use in actual practice. To improve the effectiveness of SDM in the Korean medical system, appropriate training programs and supplemental policies that guarantee sufficient application time are required.

Introduction: As research continues, new drugs will no doubt be added to the current pool of treatments for moderate-to-severe atopic dermatitis (AD). This raises the need for studies to determine prescriber preferences for different pharmacological options and the factors that influence their choice of treatment. Here we aim to explore physician preferences in the systemic treatment of moderate-to-severe AD, identify the sociodemographic characteristics that can influence physician preferences, and evaluate their satisfaction with current AD therapies. Methods: A discrete-choice experiment (DCE) survey was administered to physicians treating patients with AD in Spain. Results were analyzed using a conditional logit model to estimate the relative importance of each attribute and the maximum risk accepted to achieve therapeutic benefit. Results: A total of 28 respondents completed the DCE survey (67.9% female, mean age 45.9 years). Participants identified objective clinical efficacy and risk of severe adverse events (AEs) as the most important attributes, followed by improvement in sleep and pruritus and faster onset of action from the start of the treatment. Respondents gave less importance to mode of administration and therapeutic benefit in other atopic conditions. Respondents were willing to accept an increased risk of severe AEs and mild-to-moderate AEs leading to treatment discontinuation due to intolerance in order to obtain improvements in efficacy, sleep, and pruritus, and long-term clinical benefit. Conclusion: Our findings can help prescribers choose the most appropriate systemic AD therapy. [ABSTRACT FROM AUTHOR]

A long-acting injectable (LAI) antiretroviral therapy (ART) regimen is now available as a treatment option for virologically suppressed adults with HIV-1. This study assessed preference for a LAI regimen using an online survey of virally suppressed people living with HIV (PLWH) and physicians treating HIV in the US and Canada. Preference was elicited in a discrete choice experiment (DCE) with three choice options (switch to a LAI regimen, switch to another daily oral ART regimen, or stay on their current daily oral ART regimen) and four treatment attributes. A total of 553 PLWH and 450 physicians completed the survey. From the DCE results, 59% of PLWH were predicted to prefer a LAI over an alternative oral ART or staying on their current oral treatment, and 55–66% of physicians were predicted to recommend LAI for PLWH, depending on the treatment challenge scenario presented. PLWH indicated LAI would remove daily reminders of HIV (75%) and reduce feelings of being stigmatized (68%). A majority of PLWH and physicians preferred a LAI over oral ART to overcome treatment challenges such as daily pill burden and adherence. These benefits of LAI ART along with preferences of PLWH and physicians can help to inform ART choice. [ABSTRACT FROM AUTHOR]

Objective: How maximal safe resection of glioblastoma (GBM) is implemented in the clinical setting remains understudied. Here, we utilized a survey-based approach to understand physician perspectives on this matter., Methods: Scenarios involving GBMs were presented to physicians who were asked to select from planned subtotal resection, gross total resection (GTR), medical therapy only, or palliative care. Demographic, experience, and Likert scales of value assessment were collected., Results: In the scenario involving a corpus callosum GBM, 2.33% opted for GTR. For a right frontal GBM, 91.7% opted for GTR. In contrast, only 30.8% chose GTR of a right motor strip GBM (P < 0.001). When presented with a left motor strip GBM, fewer respondents (12.7%, P < 0.001) opted for GTR. Physicians who placed a high value on preserving physical independence were more likely to forgo GTR for right motor GBMs (hazard ratio = 0.068, 95% confidence interval: 0.47-0.97, P = 0.035), and physicians who placed a high value on their faith were more likely to opt for surgical treatments that differ from the general consensus, for instance opting for GTR of the corpus callosum GBM (hazard ratio = 4.18, 95% confidence interval: 1.63-10.74, P = 0.003). No other associations were found between the choice for GTR and other variables collected., Conclusions: Our results suggest that while maximal safe resection remains a guiding principle for GBM resection, physician preference in terms of the extent of resection varies significantly as a function of tumor location and personal values., (Copyright © 2024.

The DCE survey instruments were developed and administered to patients and physicians. A random-parameters logit model was used to estimate preference weights and conditional relative importance for these attributes.Results: A total of 200 patients with moderate to severe UC (status determined using self-reported medication history) and 200 gastroenterologists completed the survey. Patients’ average age was 42 years; most (59%) were female. Patients considered symptom control 2.5 times as important as time to symptom improvement and 5-year risk of malignancy almost as important as long-term symptom control (relative importance, 0.79 vs 0.96 for long-term symptom control); they preferred oral to subcutaneous or intravenous administration (relative importance, 0.47 vs 0.11 and 0.18, respectively). For physicians, symptom control was the most important attribute and was five times as important as the risk of malignancy.Conclusion: Both patients and physicians considered long-term symptom control the most important attribute relative to others; however, risk of malignancy was of almost-equal importance to patients but not physicians. Differences between patients’ and physicians’ preferences highlight the need for improved communication about the relevant benefits and risks of different UC treatments to improve therapeutic decision-making.Keywords: ulcerative colitis, discrete-choice experiments, maximum acceptable risk, patient preference, physician preference

Introduction/objectives: Multiple modes of administration are available for systemic lupus erythematosus (SLE) treatments. This study examined patient and physician characteristics associated with the choice of weekly subcutaneous (SC) injection or monthly intravenous (IV) infusion for an unspecified SLE treatment. Methods: This was a cross-sectional, US web-based survey using a direct elicitation, stated-preference methodology (HO-16-16706). Two hundred patients and 200 physicians were asked to choose between IV or SC administration in a hypothetical scenario. Pairwise and multivariate analyses estimated the odds ratio (OR) for the likelihood of choosing SC over IV for respondent characteristics. Results: Among patients, taking non-steroidal anti-inflammatory drugs increased the likelihood of choosing SC injection (OR 3.884), whilst having SLE-related skin problems, a fear of needles or self-injection, and never needing help around the house decreased the likelihood (OR 0.28, 0.13, 0.12, respectively; all p ≤ 0.05). Among physicians, > 95% recommended SC injection for patients who live or work far from an infusion center, prefer SC administration, and never or rarely miss medication doses. Physician characteristics including age and treatment practice also influenced choice. Conclusions: Patient and physician characteristics influence choice of SC versus IV therapy for SLE. These findings might inform shared decision-making, which could lead to improved patient outcomes. Key Points • Data regarding patient and physician preference for different modes of administration of SLE therapy are sparse. • This cross-sectional, US web-based study showed that patient and physician characteristics influence choice of SC versus IV therapy for SLE. • A degree of disconnect exists between how factors influence patients' choice and how those characteristics influence physicians' choice of SLE treatment mode of administration. • The findings from this study might inform shared decision-making, which could improve alignment between treatment choice and patient preferences, treatment satisfaction, adherence, and improved patient outcomes.

Background Vasoactive drugs are frequently used in combination with endoscopic variceal ligation (EVL) in treatment of acute esophageal variceal bleeding (EVB). The aim of study was to assess physicians’ preference of vasoactive agents in acute EVB, their reasons of preference and efficacy and safety of these short course regimens. Methods Cirrhotic patients with suspected EVB were screened (n = 352). Eligible patients were assigned based on the physician’s preference to either somatostatin (group S) or terlipressin (group T) followed by EVL. In group S, intravenous bolus (250 µg) of somatostatin followed by 250 µg/hour was continued for three days. In group T, 2 mg bolus injection of terlipressin was followed by 1 mg infusion every 6 h for three days. Results A total of 150 patients were enrolled; 41 in group S and 109 in group T. Reasons for physician preference was convenience in administration (77.1%) for group T and good safety profile (73.2%) for group S. Very early rebleeding within 49–120 h occurred in one patient in groups S and T (p = 0.469). Four patients in group S and 14 patients in group T have variceal rebleeding episodes within 6–42 d (p = 0.781). Overall treatment-related adverse effects were compatible in groups S and T (p = 0.878), but the total cost of terlipressin and somatostatin differed i.e., USD 621.32 and USD 496.43 respectively. Conclusions Terlipressin is the preferred vasoactive agent by physicians in our institution for acute EVB. Convenience in administration and safety profile are main considerations of physicians. Safety and hemostatic effects did not differ significantly between short-course somatostatin or terlipressin, although terlipressin is more expensive.

A substantial proportion of this spending occurs during orthopedic (eg, hip and knee) arthroplasties – two high-volume hospital procedures. The implants used in these procedures are commonly known as physician preference items (PPIs), reflecting the physician’s choice of implant and vendor used. The foundations for this preference are not entirely clear. This study examines what implant and vendor characteristics, as evaluated by orthopedic surgeons, are associated with their preference. It also examines other factors (eg, financial relationships and vendor tenure) that may contribute to implant preference. Methods: We surveyed all practicing orthopedic surgeons performing 12 or more implant procedures annually in the Commonwealth of Pennsylvania. The survey identified each surgeon’s preferred hip/knee vendor as well as the factors that surgeons state they use in selecting that primary vendor. We compared the surgeons’ evaluation of multiple characteristics of implants and vendors using analysis of variance techniques, controlling for surgeon characteristics, hospital characteristics, and surgeon–vendor ties that might influence these evaluations. Results: Physician’s preference is heavily influenced by technology/implant factors and sales/service factors. Other considerations such as vendor reputation, financial relationships with the vendor, and implant cost seem less important. These findings hold regardless of implant type (hip vs knee) and specific vendor. Conclusion: Our results suggest that there is a great deal of consistency in the factors that surgeons state they use to evaluate PPIs such as hip and knee implants. The findings offer an empirically derived definition of PPIs that is consistent with the product and nonproduct strategies pursued by medical device companies. PPIs are products that surgeons rate favorably on the twin dimensions of technology and sales/service. Keywords: physician’s preference, surgeons, orthopedics, hip implants, PPIs

The study included 10 eyes from 10 subjects diagnosed with a retinal/choroidal disease. Deidentified images were compiled into a survey and sent to retina specialists in various countries. The survey presented masked SD and SS images of each eye for each retinal sublayer side by side. Respondents were asked about their image preference and impact on clinical management. A priori and post hoc preferences for SD vs SS were collected.Results: Fifty-four retina specialists responded to the survey. Median years in practice was 3.00 (interquartile range [IQR] 1.50–17.00). At baseline, 23 (48%) physicians owned an OCTA machine. The majority of physician responses showed a preference for the SS over SD OCTA, independent of the retinal pathology shown (n=454 overall responses, 74%). Nevertheless, the majority indicated that both SD and SS would be equally valuable in informing clinical decisions (n=374 overall responses, 61%).Conclusion: These findings indicate that the majority of retina specialists surveyed prefer SS over SD OCTA based on image quality, regardless of the retinal pathology shown. Regarding the clinical utility of each modality, the majority of physicians perceive SD and SS as equally effective.

Respondents were asked to choose between hypothetical antipsychotic profiles defined by efficacy, safety, and mode of administration. Data were analyzed using random-parameters logit and probit models.Results: Patients (N=214) and physicians (N=438) preferred complete improvement in positive symptoms (severe to none) as the most important attribute, compared with improvement in any other attribute studied. Both respondents preferred 3-month and 1-month injectables to oral formulation (P30%. For patients, adherent: 10.1% (95% CI: 6.1–14.1), nonadherent: the change in efficacy studied was regarded as unimportant.Conclusion: Improvement in positive symptoms was the most important attribute. Patients and physicians preferred LAIs over oral antipsychotics, with physicians showing a greater preference for 3-month over 1-month LAI. Physicians and patients were willing to accept reduced efficacy in exchange for switching a patient from an oral formulation to a LAI.

Purpose: Although warfarin has historically been the standard of care for preventing ischemic stroke in patients with nonvalvular atrial fibrillation (NVAF), the use of direct oral anticoagulants (DOACs) is rapidly increasing. In this study, we examined the demographic and clinical characteristics of patients continuing warfarin therapy and investigated reasons for warfarin continuation. Patients and methods: Each study site consecutively registered 10 patients with NVAF who had been taking warfarin for at least 12 months. Demographic and clinical characteristics and international normalized ratio (INR) values were collected from medical records. Physicians responded to questionnaires exploring reasons for continuing warfarin therapy. Results: Overall, 313 patients treated with warfarin were registered at 33 sites. Mean ± SD age was 76.4±9.6 years; 62.9% of patients were male. The proportion of patients with INR values in the therapeutic range was 74.6% and 48.8% among patients aged ≥70 years and ≥70 years, respectively. Over half of the patients (51.4%) had been advised to switch from warfarin to DOACs; the primary physician-reported reason for this recommendation was superior safety and effectiveness. However, patients reported continuing warfarin because of the high price of DOACs (47.2%) and long-term positive experiences with warfarin (31.7%). The remaining 48.6% of patients with NVAF had never been counseled by their physicians about DOACs as an alternative to warfarin. For 76% of these patients, physicians favored warfarin for medical reasons, such as impaired renal function and controlled INR, but in the remaining patients, medical reasons for continuing warfarin were lacking. Conclusion: Approximately half of the patients in this study were informed of warfarin alternatives primarily for improved efficacy and safety, but elected not to change regimens because of the high price of DOACs and long-term positive experiences with warfarin. In the remaining half, physician preference or specific patient characteristics prevented a change in therapy. [ABSTRACT FROM AUTHOR]

Purpose As older women with breast cancer (BC) are underrepresented in trials, it is often unclear what represents the best treatment option for this patient group. To understand how oncologists approach the management of BC in older patients, we assessed their treatment recommendations. Methods In an online survey, 106 surgical, 37 radiation and 31 medical oncologists provided a treatment recommendation for hypothetical patients aged >70 years. Scenarios included loco-regional therapy with patient age varying at 76 and 84 years; systemic therapy with Karnofsky performance score varying at 90 and 50%; neo-adjuvant therapy; and adjuvant chemotherapy in triple-negative BC. Results Participants would less often recommend breast-conserving surgery plus radiotherapy for an 84 versus a 76-year-old patient (56% versus 73%, p = 0.001). They would more often accept omission of radiotherapy after breast-conserving surgery in older than in younger patients, if the patient wished to avoid this therapy (26% versus 4%, p < 0.001). All participants would propose systemic therapy for a high-recurrence risk patient with a good performance score, and 92% would still recommend therapy if the patient had a poor score (p < 0.001). Neo-adjuvant hormonal therapy followed by breast-conserving surgery for a large tumour was recommended by 27% of the participants. Adjuvant chemotherapy for an otherwise healthy woman with triple-negative BC was considered by 83% of the participants. Conclusions Patient age and performance status influenced specialists' treatment recommendations. The observed recommendations for the treatment scenarios under investigation differ from older women's actual treatment. This discrepancy highlights the need for studies specifically targeting older patients. [ABSTRACT FROM AUTHOR]

Background China has one of the highest cesarean delivery rates in the world, with most cesareans done without indication. Methods Observation of how perinatal care is delivered in a range of Shanghai hospitals was done to gain insight into the 50 percent cesarean delivery rate. A mixed methods approach combined a descriptive structured survey of obstetric services with standardized interview with obstetricians and qualitative observation of obstetric services in six different Shanghai obstetric facilities. Results The volume was extremely high: physicians in public hospitals routinely saw up to 80-120 prenatal patients per day. Frequent prenatal testing substituted for time spent in patient-doctor interactions. Family members were not allowed in delivery wards where women labored alone. Obstetrics services had low levels of nursing support and anesthesia for labor. Physical space favored rapid surgical turnover over longer labor. Physicians reported practical incentives to perform cesarean sections. Discussion Cesarean delivery was an efficient way to move patients through the systems observed, given the staffing and physical limitations of the public facilities. Physicians reported that patients and families perceived cesarean delivery as safer. Physicians also reported fear of charges of malpractice, for which they might be found to be financially liable or in physical danger. Societal expectations are high, and in a 'one child' society, perception that cesarean section was safer may also have driven cesarean rates. Given the end of the One Child Policy, the preference for cesarean delivery may change. [ABSTRACT FROM AUTHOR]

In the European Union, labels (Summaries of Product Characteristics, SmPCs) of biosimilars and their reference products are in many instances almost identical (following a generic approach) despite different data requirements for the authorization of biosimilars and generics. To understand physicians' preferences on type and detail of information in the biosimilar label and their use of information sources when prescribing biologics including biosimilars, EuropaBio surveyed 210 physicians across seven European countries. Among surveyed physicians, 90.5% use the label frequently or occasionally as an information source and 87.2% deemed a clear statement on the origin of data helpful or very helpful. When comparing excerpts from the label of an authorized biosimilar and modified texts with additional information, 78.1–82.9% preferred the samples with additional information. This survey shows that the label is an appropriate vehicle for providing physicians with information about biologics and that physicians prefer more product-specific information in the biosimilar label.

Bone metastases and associated skeletal-related events (SREs) are common in patients with advanced breast, lung, and prostate cancer. Bone-targeted agents (BTAs) are available for the treatment of bone metastases, but little is known about patients' and physicians' preferences for the various attributes of these agents. We evaluated preferences for BTAs used to prevent SREs among patients with bone metastases and physicians involved in treating such patients in Turkey. Participants completed an online discretechoice experiment survey of 10 questions, choosing between pairs of hypothetical treatment profiles, defined by five BTA attributes: time to first SRE, time to worsening of pain, annual risk of osteonecrosis of the jaw (ONJ), annual risk of renal impairment, and administration regimen. The analysis included 91 patients and 99 physicians. Both groups rated annual risk of renal impairment, time to worsening of pain, and time to first SRE as the most important BTA attributes. For patients, the preference weights for all levels of these attributes were significantly different, whereas for physicians, preference weights were significantly different for all levels except time to a 2-point increase in "Brief Pain Inventory" score by 6 months or 10 months. Annual risk of ONJ was judged by patients and physicians to be the least important of the BTA attributes. This study adds to the information available on the preferences of patients and physicians for BTAs and provides useful data to aid clinicians in decision-making by understanding the treatment goals that are important to patients in Turkey.

Background context Whereas the costs of primary surgery, revisions, and selected complications for adult spinal deformity (ASD) have been individually reported in the literature, the total costs over several years after surgery have not been assessed. The determinants of such costs are also not well understood in the literature. Purpose This study analyzes the total hospital costs and operating room (OR) costs of ASD surgery through extended follow-up. Study design/setting Single-center retrospective analysis of consecutive surgical patients. Patient sample Four hundred eighty-four consecutive patients undergoing surgical treatment for ASD from January 2005 through January 2011 with minimum three levels fused. Outcome measures Costs were collected from hospital administrative data on the total hospital costs incurred for the operation and any related readmissions, expressed in 2010 dollars and discounted at 3.5% per year. Detailed data on OR costs, including implants and biologics, were also collected. Methods We performed a series of paired t tests and Wilcoxon signed-rank tests for differences in total hospital costs over different follow-up periods. The goal of these tests was to identify a time period over which average costs plateau and remain relatively constant over time. Generalized linear model regression was used to estimate the effect of patient and surgical factors on hospital inpatient costs, with different models estimated for different follow-up periods. A similar regression analysis was performed separately for OR costs and all other hospital costs. Results Patients were predominantly women (n=415 or 86%) with an average age of 48 (18–82) years and an average follow-up of 4.8 (2–8) years. Total hospital costs averaged $120,394, with primary surgery averaging $103,143 and total readmission costs averaging $67,262 per patient with a readmission (n=130 or 27% of all patients). Operating room costs averaged $70,514 per patient, constituting the majority (59%) of total hospital costs. Average total hospital costs across all patients significantly increased (p<.01) after primary surgery, from $111,807 at 1-year follow-up to $126,323 at 4-year follow-up. Regression results also revealed physician preference as the largest determinant of OR costs, accounting for $14,780 of otherwise unexplained OR cost differences across patients, with no significant physician effects on all other non-OR costs (p<.05). Conclusions The incidence of readmissions increased the average cost of ASD surgery by more than 70%, illustrating the financial burden of revisions/reoperations; however, the cost burden resulting from readmissions appeared to taper off within 5 years after surgery. The estimated impact of physician preference on OR costs also highlights the variation in current practice and the opportunity for large cost reductions via a more standardized approach in the use of implants and biologics.

In today's economy, it is imperative that nurses exhibit stewardship for their organization's resources and help ensure that purchasing decisions are sound. Regardless of the decision-making method chosen, a formal, consistent review process that evaluates cost, compares products, examines implications, analyzes risk, uses evidence, and includes safety and outcome measures is vital to success. Clinical Quality Value Analysis (CQVA) is a product evaluation platform that can be used to determine whether a proposed product or service will add value to the organization as well as improve patient outcomes. Using CQVA for a proposed product or service is a five-step process: assess, plan, design, implement, and measure/sustain. [ABSTRACT FROM AUTHOR]

Prophylaxis may be beneficial for patients with severe haemophilia A who have developed inhibitors to factor VIII. The aim of this study was to determine physicians' preferences for medication attributes in the prophylactic treatment of this patient population. Haematologists from Europe ( EU) and the United States ( US) participated in a discrete choice exercise to explore their preferences for medication attributes (efficacy, cost, scientific evidence, dosing frequency and administration time) associated with prophylaxis for severe haemophilia A in patients with inhibitors to factor VIII. Physicians' preferences for medication attributes were assessed through completion of 25 trade-off tasks that included a choice between two hypothetical medications each comprised of one randomized level of each medication attribute. Participants also completed a sociodemographic questionnaire. Data were analysed using a random effects logit model. Participants ( N = 36: US = 19; EU = 17) were 80.6% men, had a mean of 19.8 years ( SD ± 8.1) [range 6-35] of practice experience. The physicians treated an average of 5.7 (±5.5) patients with severe haemophilia A and inhibitors per month and reported treating 36.2% of these patients prophylactically. The most important medication attributes for prophylactic treatment were efficacy [Relative Importance ( RI) = 35.0%] and scientific evidence ( RI = 34.1%), whereas treatment cost (12.0%), dosing frequency (10.8%) and administration time (8.2%) were less important. Results were similar across the EU and US. Efficacy and scientific evidence are the primary considerations for physicians' choice of prophylactic medications for use in this patient population.

Objective. Treatment planning of radiation therapy is a time-consuming task. It is desirable to develop automatic planning approaches to generate plans favorable to physicians. The purpose of this study is to develop a deep learning based virtual physician network (VPN) that models physician's preference on plan approval for prostate cancer stereotactic body radiation therapy (SBRT). Approach. VPN takes one planning target volume (PTV) and eight organs at risk structure images, as well as a dose distribution of a plan seeking approval as input. It outputs a probability of approving the plan, and a dose distribution indicating improvements to the input dose. Due to the lack of unapproved plans in our database, VPN is trained using an adversarial framework. 68 prostate cancer patients who received 45Gyin 5-fraction SBRT were selected in this study, with 60 patients for training and cross validation, and 8 patients for independent testing. Main results. The trained VPN was able to differentiate approved and unapproved plans with Area under the curve 0.97 for testing data. For unapproved plans, after applying VPN's suggested dose improvement, the improved dose agreed with ground truth with relative differences2.03±2.17%for PTVD98%,0.49±0.29%for PTVV95%,3.08±2.24%for penile bulbDmean,3.73±2.20%for rectumV50%,and2.06±1.73%for bladderV50%. Significance. VPN was developed to accurately model a physician's preference on plan approval and to provide suggestions on how to improve the dose distribution., (© 2022 Institute of Physics and Engineering in Medicine.)

Objectives Little is known about doctors' preferences regarding public report card design. Taiwan just announced the first diabetes report card on April 2008. The aim of this study was to investigate the Diabetes Mellitus (DM) providers' preferences towards four report card attributes: update frequency, risk adjustment, content information and display format. Methods A discrete choice questionnaire was mailed to hospital and primary care doctors in the northern part of Taiwan, with 221 study targets. The response rate was 29%. Results Using random effect logistic regression, doctors' preference attribute rankings were risk adjustment for patients (44.7%), content information (25.2%), display format (18.3%) and update frequency (11.8%). One-year update frequency, risk adjustment, detailed scores of technical quality and interpersonal quality and bar chart display were the most important items noted in our survey. Conclusions This is the first study to investigate provider's preferences for a diabetes report card. It enables the policy maker to clearly see the implication of trade-offs between different choices when designing a report card that doctors will like. Our findings suggest that doctors do not favour the ‘less is more’ principle, or the higher frequency of updates that patients may prefer. Rather, our findings suggest that risk adjustment and more information content are the most important factors for doctors. Future studies should use discrete choice experiment on different aspects of report card design, such as vulnerable patients or health care administrations. [ABSTRACT FROM AUTHOR]

Aims: An increasing dialysis population and insufficient supply of transplant organs necessitate that patients are carefully evaluated prior to registration on the national waiting list to ensure effective utilization of a scarce resource. We have assessed listing practice in two renal units within the North of England Transplant Alliance. Methods: Demographic, ethnic and clinical data were recorded at initiation of dialysis for patients from two northern English cities, Bradford (n = 209) and Hull (n = 202) between 1994 - 2000. Patients were stratified by two co-morbidity scoring systems. Multivariate and survival analyses were undertaken by registration status. Results: Overall, 159 patients were registered onto the waiting list. Stratification by co-morbidity predicted listing at high and low risk, but with overlap at medium scores. There was no difference in overall co-morbid burden between the two centers (p =0.161 and 0.316, respectively, for two scoring systems). Logistic regression analysis demonstrated a center effect, Hull having an odds ratio for listing of 0.48 compared to Bradford (p = 0.041). Short- and medium-term survival in the listed group was high regardless of co-morbid score (22 vs 174 deaths in the non-listed group). In this cohort, five patients died with grafts, another three died whilst active on the waiting list. The remaining 14 patients had been removed from the list prior to death. Summary: Co-morbidity scoring schemes are unlikely to be sophisticated enough to accurately identify those who would most benefit from transplantation, and the value of clinical judgment is well-shown in this study. Standardization of registration will result in more equitable allocation of organs. However, this study has demonstrated that there are differences in listing practices even within a single alliance. Continuous assessment will allow judicious removal from the waiting list of patients who have developed an unacceptable co-morbid burden. [ABSTRACT FROM AUTHOR]

A major goal of this research was to identify an antibiotic education intervention that would increase young adult consumers' preference for physicians who do not unnecessarily prescribe antibiotics for simple acute upper respiratory infections (URIs). Results clearly showed that consumers who read the CDC brochure entitled, "A New Threat to Your Health: Antibiotic Resistance" significantly preferred the physician who would not prescribe antibiotics for a URI on Day 3. They also inferred that this physician had significantly greater ability than the physician who would prescribe antibiotics. In contrast, consumers who did not read the CDC brochure significantly preferred the physician who would prescribe antibiotics for a URI on Day 3. They also inferred that this physician had significantly greater ability and greater concern for patients than the physician who would not prescribe antibiotics. Thus, consumers with low knowledge exhibited a treatment bias and preferred physicians who provided more treatment, and consumer education successfully reversed the treatment bias.

Summary. In comparison with other biotechnology substitutions, the adoption of recombinant Factor VIII (rFVIII) has been relatively slow. We sent a postal questionnaire to all Dutch haemophilia patients and haemophilia-treating physicians, to determine which factors predict whether a patient uses plasma-derived FVIII (pdFVIII) or rFVIII and to investigate patients’ and doctors' opinions on both products. Fifty-six per cent of patients received rFVIII. This percentage varied widely between centres. Only one doctor would choose to use pdFVIII if he suffered from haemophilia A himself, and 74% would choose to use rFVIII. Younger patients, those not infected with the human immunodeficiency virus or hepatitis C, and those who did not have family members who used pdFVIII switched more often from pdFVIII to rFVIII. Patients who rated themselves as innovative, who had family members who used rFVIII, and those who were treated in a large haemophilia treatment centre were also more likely to have switched. For physicians and patients alike, the respondents generally did not see large differences between rFVIII and pdFVIII, except for the risk of infections and the knowledge of long-term effects (both larger for pdFVIII). Although haemophilia patients represent one of the most empowered patient groups, physicians appear to have been influential in choosing between pdFVIII and rFVIII. [ABSTRACT FROM AUTHOR]

Background: Evidence of the ethical appropriateness and clinical benefits of shared decision-making (SDM) are accumulating. This study aimed to not only identify physicians' perspectives on SDM, and practices related to end-of-life care in particular, but also to gauge the effect of SDM education on physicians in Korea., Methods: A 14-item questionnaire survey using a modified Delphi process was delivered to nephrologists and internal medicine trainees at 17 university hospitals., Results: A total of 309 physicians completed the survey. Although respondents reported that 69.9% of their practical decisions were made using SDM, 59.9% reported that it is not being applied appropriately. Only 12.3% of respondents had received education on SDM as part of their training. The main obstacles to appropriate SDM were identified as lack of time (46.0%), educational materials and tools (29.4%), and education on SDM (24.3%). Although only a few respondents had received training on SDM, the proportion of those who thought they were using SDM appropriately in actual practice was high; the proportion of those who chose lack of time and education as factors that hindered the proper application of SDM was low., Conclusion: The majority of respondents believed that SDM was not being implemented properly in Korea, despite its use in actual practice. To improve the effectiveness of SDM in the Korean medical system, appropriate training programs and supplemental policies that guarantee sufficient application time are required.

Ketotifen 1 mg b.d. (oral) and sodium cromoglycate 20 mg q.i.d. (inhalation) were compared in a double-blind crossover trial in 43 asthmatic outpatients. Comparison of diary card scores and pulmonary function tests showed significant improvement over a 12 week period on each drug. Comparison of the diary card scores and pulmonary function tests showed no significant difference between the drugs after 12 weeks of treatment. Twenty-six patients experienced sedation and/or lethargy whilst on ketotifen and 11 patients had similar side effects whilst on cromoglycate. Physician preferences based on diary card and pulmonary function data showed an approximately equal number of preferences for each medication and also a small group of patients in which no preference could be made. The present trial suggests that both ketotifen and cromoglycate are effective in the management of outpatient asthma. When all the patients are considered as a group no distinction can be made between the two drugs; on the basis of physician assessment of each patient, it appears that some patients may do better on ketotifen and others on cromoglycate.

Background: Vasoactive drugs are frequently used in combination with endoscopic variceal ligation (EVL) in treatment of acute esophageal variceal bleeding (EVB). The aim of study was to assess physicians' preference of vasoactive agents in acute EVB, their reasons of preference and efficacy and safety of these short course regimens., Methods: Cirrhotic patients with suspected EVB were screened ( n  = 352). Eligible patients were assigned based on the physician's preference to either somatostatin (group S) or terlipressin (group T) followed by EVL. In group S, intravenous bolus (250 µg) of somatostatin followed by 250 µg/hour was continued for three days. In group T, 2 mg bolus injection of terlipressin was followed by 1 mg infusion every 6 h for three days., Results: A total of 150 patients were enrolled; 41 in group S and 109 in group T. Reasons for physician preference was convenience in administration (77.1%) for group T and good safety profile (73.2%) for group S. Very early rebleeding within 49-120 h occurred in one patient in groups S and T ( p  = 0.469). Four patients in group S and 14 patients in group T have variceal rebleeding episodes within 6-42 d ( p  = 0.781). Overall treatment-related adverse effects were compatible in groups S and T ( p  = 0.878), but the total cost of terlipressin and somatostatin differed i.e., USD 621.32 and USD 496.43 respectively., Conclusions: Terlipressin is the preferred vasoactive agent by physicians in our institution for acute EVB. Convenience in administration and safety profile are main considerations of physicians. Safety and hemostatic effects did not differ significantly between short-course somatostatin or terlipressin, although terlipressin is more expensive., Competing Interests: Lee Yeong Yeh is an Academic Editor for PeerJ., (©2019 Chuah et al.)
