Quantifying preferences for urea cycle disorder treatments using a discrete choice experiment.

AIMS: Urea cycle disorders (UCDs) can cause ammonia accumulation and central nervous system toxicity. Nitrogen-binding medications can be efficacious, but certain attributes may negatively impact adherence. This study sought to quantify the administration-related attributes influencing overall prescription selection and patient adherence. METHODS: A web-based, quantitative survey including discrete choice experiment (DCE) methodology captured responses from health care providers for patients with UCDs. A series of hypothetical treatment profile sets with attributes such as route of administration, taste/odor, preparation instructions, packaging, dose measurement, and weight use restrictions were presented. From 16 sets of 3 hypothetical product profiles, respondents evaluated attributes most preferred for prescription selection or patient adherence. Attributes assumed a higher overall preference if relative importance (RI) scores were >16.67% (the value if all attributes were of equal importance). Preference weight scores were assessed. A nine-point Likert scale assessed respondent attitudes, such as satisfaction. RESULTS: A total of 51 respondents completed the survey. Respondents reported dissatisfaction with current treatments (mean [SD] = 5.4 [1.7]). For prescription selection, four attributes achieved RI >16.67%: taste/odor (24%), weight restrictions (21%), preparation instructions (18%), and route of administration (17%). For adherence, three attributes related to administration achieved RI >16.67%: taste/odor (28%), preparation instructions (21%), and route of administration (17%). Preference weights for "taste/odor masked" were higher than "not taste/odor masked" for prescription selection (mean [SD]; 1.52 [1.10] vs -1.52 [1.10]) and treatment adherence (73.8 [55.2] vs -73.8 [55.2]). LIMITATIONS: This study contained a relatively small sample size. Survey respondent selection, the use of hypothetical product profiles, and exclusion of non-pharmacologic treatment options could have contributed to potential biases. CONCLUSIONS: Among attributes tested, taste/odor was the most important attribute influencing overall preference for both prescribing and patient adherence, with taste/odor masking preferred. Optimizing nitrogen-binding medications through masking taste/odor may support improved patient adherence and outcomes in UCDs.

Real-world treatment preferences among health care providers in the United States in selecting disease modifying therapies for patients with multiple sclerosis: a discrete choice experiment.

AIMS: Health care providers (HCPs) treating multiple sclerosis (MS) in clinical practice have numerous disease-modifying therapies (DMTs) to consider when evaluating treatment options. This study assessed the treatment preferences of HCPs in the United States, both direct (explicit) and derived (explicit and implicit), when selecting MS DMTs based on clinical and logistical treatment attributes. MATERIALS AND METHODS: A 45-minute web-enabled questionnaire was administered to HCPs who manage patients with MS to assess the importance of treatment attributes. HCPs were recruited through an online panel. This study examined treatment attributes relevant to treatment decisions in MS, with a focus on the burden to HCPs and their staff, as well as HCP attitudes toward various aspects of MS care such as diagnosis, treatment prioritization, and ease of initiating or switching DMTs. The study also employed a discrete choice experiment (DCE) to assess direct and derived treatment preferences. RESULTS: The study recruited 145 HCPs. Direct assessments (a score of greater than 7.0 was considered important) suggested that safety (mean importance rating = 7.8/9) and relative risk reduction in relapses (7.6/9) and disability progression (7.5/9) were most important when selecting DMTs. In contrast, derived importance from the DCE (higher points corresponding to greater importance) suggested that logistical attributes such as dose frequency (mean relative attribute importance = 17.5%), dose titration (10.3%), formulation (9.4%), and volume of calls (9.1%) were important considerations, along with efficacy (16.5%), safety (9.8%), and gastrointestinal tolerability (9.4%). LIMITATIONS: This study may have been subject to selection bias due to the application of eligibility criteria, the convenient sampling recruitment methodology, and recruitment of HCPs with internet access. CONCLUSION: In the direct assessment, clinical attributes were chosen as the most important treatment attributes by HCPs. However, in the DCE, derived treatment decisions rated logistical attributes as also being as important in treatment choice.

In this study, researchers aimed to understand what multiple sclerosis (MS) neurologists, nurse practitioners, and physician assistants think is most important when choosing medicines for their patients. They surveyed 145 health care providers (HCPs) in the United States for this study. The HCPs reported that safety and reducing the risk of relapses and disability were most important when selecting medicines. Additionally, the researchers used a method called a discrete choice experiment to determine the relative importance of medication characteristics to HCPs. They found that additional factors, such as how often the medicine needs to be taken, how it is given, and how easy it is to use, were also very important. The study may not represent the opinions of all HCPs due to the number of participants and participation criteria.

Essential tremor patients experience significant burden beyond tremor: A systematic literature review.

Background: Essential tremor (ET) is among the most common movement disorders in adults. While ET is diagnosed and primarily characterized by the presence of tremor, it also can impact cognition, sleep, mood, and motor functioning more broadly. The manifestations of ET can have various consequences, including difficulty with activities of daily living (ADL), embarrassment, and overall decline in health-related quality of life, which have not been fully explored in prior studies. Objective: We performed a systematic literature review to comprehensively characterize the burden experienced by patients with ET from the clinical and humanistic perspectives, focusing on outcomes beyond tremor. Methods: This systematic literature review followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Searches in PubMed, Embase, and Cochrane Library identified original, observational studies of the clinical and humanistic burden in adult patients with ET published in English between 2010 and 2020. Studies assessing epidemiology, treatment patterns, or disease management were excluded. Search results were screened according to pre-determined eligibility criteria. Data from included studies were collected, independently verified, and qualitatively synthesized. Results: Following the screening of 2,303 records and 145 full-text articles, 39 studies were identified. There was significant heterogeneity in study designs, statistical approaches, and patient cohorts across the included studies. Patients with ET in these studies exhibited more severe disabilities and reduced independence compared to healthy individuals, and they often struggled to perform ADL and relied on caregivers for physical and emotional support. Patients also experienced various issues with movement and balance, increased risk of falls, depression, anxiety, poor sleep quality, and psychosocial consequences including embarrassment, apathy, and enfeeblement. Conclusion: A systematic literature review of non-tremor manifestations and/or consequences of ET identified far-reaching negative impacts on patients' ability to function independently and revealed accompanying psychosocial effects, including social fear and embarrassment. The reduced function and psychosocial deficits observed in patients with ET result in significant clinical and humanistic burdens, decreasing quality of life. Future studies should evaluate this condition beyond the tremor itself to provide an improved understanding of the multi-dimensional burden of the disease, thereby highlighting the need to diagnose and appropriately manage patients with ET.

Assessing the Burden of Illness Associated with Acquired Generalized Hypoactive Sexual Desire Disorder.

Background: Hypoactive sexual desire disorder (HSDD), which affects ∼10% of women in the United States, is defined as the persistent or recurrent deficiency/absence of sexual desire accompanied by personal distress. Although HSDD impacts patient quality of life and interpersonal relationships, the disorder often goes unaddressed or untreated. Recent studies of the burden of illness in women with HSDD, especially premenopausal women, are limited. Materials and Methods: A 45-minute web-based survey was designed to investigate the experience of women seeking treatment for HSDD and the impact of this disorder on several psychosocial aspects of women's lives. Women were recruited from an online panel of patients who participated in research studies for compensation. Validated questionnaires assessed sexual function (Female Sexual Function Index) and health-related quality of life (12-Item Short Form Survey [SF-12]), including mental and physical component scores. Results: A total of 530 women, aged ≥18 years, diagnosed with acquired generalized HSDD were included in the study. Premenopausal women indicated greater overall HSDD symptom burden compared with postmenopausal women. Patients with HSDD reported lower SF-12 scores compared with the general population. A multivariable regression analysis demonstrated that psychosocial factors influencing the burden of HSDD, including interference with their relationship with their partner (ß = -0.18; p < 0.005), mental and emotional well-being (ß = -0.23; p < 0.005), and household and personal activities (ß = -0.23; p = 0.02), negatively affected SF-12 mental component scores. Conclusions: HSDD symptom burden was found to be negatively and statistically significantly associated with patients' mental health; the impact was greater among premenopausal women compared with postmenopausal women.

Transition of Care from Pediatric to Adult Care in Eosinophilic Esophagitis: Insights From a Patient Perspective Survey.

ABSTRACT: Eosinophilic esophagitis (EoE) is a chronic immune-mediated disease. Patients with a childhood diagnosis require ongoing disease management in adulthood; however, knowledge of the patient experience during pediatric to adult healthcare transition is lacking. Here, an online survey captured patient perceptions of the challenges faced by patients with EoE in the United States during transition to adult healthcare, and which resources, if implemented, could better support transition. Of 67 respondents, 91% (n = 61) were under adult care at the time of survey completion. Aspects that respondents struggled with most included meal planning, food shopping, cooking/finding foods that did not exacerbate their condition, and knowledge of insurance coverage. Although most respondents reported confidence in having the knowledge to manage their EoE, almost half of the respondents worried about managing their condition in the future. Resources detailing diet, medication and insurance management strategies could support the transition to adult healthcare for patients with EoE.

New-Onset Gout as an Independent Risk Factor for Returning to Dialysis After Kidney Transplantation.

BACKGROUND: The causal relationship between gout and renal transplant outcomes is difficult to assess due to multiple interacting covariates. This study sought to estimate the independent effect of new-onset gout on renal transplant outcomes using a methodology that accounted for these interactions. METHODS: This study analyzed data on patients in the US Renal Data System (USRDS) who received a primary kidney transplant between 2008 and 2015. The exposure was new-onset gout, and the primary endpoint was returning to dialysis >12 months postindex date (transplant date). A marginal structural model (MSM) was fitted to determine the relative risk of new-onset gout on return to dialysis. RESULTS: 18 525 kidney transplant recipients in the USRDS met study eligibility. One thousand three hundred ninety-nine (7.6%) patients developed new-onset gout, and 1420 (7.7%) returned to dialysis >12 months postindex. Adjusting for baseline and time-varying confounders via the MSM showed new-onset gout was associated with a 51% increased risk of return to (RR, 1.51; 95% CI, 1.03-2.20). CONCLUSIONS: This finding suggests that new onset gout after kidney transplantation could be a harbinger for poor renal outcomes, and to our knowledge is the first study of kidney transplant outcomes using a technique that accounted for the dynamic relationship between renal dysfunction and gout.

The burden of familial chylomicronemia syndrome in Canadian patients.

BACKGROUND: Familial chylomicronemia syndrome (FCS) is a rare autosomal recessive disorder characterized by persistent extreme hypertriglyceridemia as a result of lipoprotein lipase deficiency. Canada is an important region for FCS research due to the high prevalence rates. The burden of illness and quality of life of Canadian patients, however, have been inadequately addressed in the literature. OBJECTIVE: To understand the burden of illness of FCS on Canadian patients' lives. METHODS: IN-FOCUS is a global web-based survey open to patients with FCS, including patients in Canada. This survey captured information on diagnostic experience, symptoms, comorbidities, disease management, and impact on multiple life dimensions. RESULTS: A total of 37 Canadian patients completed the IN-FOCUS survey. Patients saw a mean of 4 physicians before their FCS diagnosis despite 89% reporting an FCS family history. Patients experience multiple physical, emotional, and cognitive symptoms in addition to FCS-related comorbidities. Notably, 35% of those who answered the survey have experienced acute pancreatitis, averaging 14 lifetime episodes per patient. In the preceding 12 months, 46% of patients had an FCS-related hospitalization, averaging 3 nights' stay. All respondents restricted fat intake, with 27% following an extremely low-fat diet. Despite this, 100% of patients reported fasting TG levels above the normal range. FCS impacted career choice in nearly all patients (97%) and employment status in all patients who were employed part time, disabled, or homemakers, causing many (> 75%) to choose careers below their level of abilities. Furthermore, 2/3 of patients reported FCS had a significant impact on their decision regarding whether to have children. Most report significant interference with their emotional/mental well-being, social relationships, and the majority were concerned about the long-term impact of FCS on their health (89%). CONCLUSIONS: This study provides the first and largest study to investigate the multi-faceted psychosocial and cognitive impacts of FCS on patients. Canadian patients with FCS experience significant multi-faceted burdens that diminish their quality of life, employment opportunities, social relationships, and mental/emotional well-being. These results highlight the need for greater disease awareness, improved clinical diagnosis, broader clinical management for heterogenous symptoms, and more effective treatment options for FCS.

A Retrospective Cohort Study of the Effect of Gout on Mortality Among Patients with a History of Kidney Transplantation.

BACKGROUND Kidney transplantation is associated with increased prevalence of gout. However, evidence of the effect of gout on long-term kidney transplantation outcomes is mixed. This study examined mortality risk among patients with a history of kidney transplantation with vs. without gout. MATERIAL AND METHODS A retrospective study was conducted using Medicare Fee-for-Service administrative claims of patients with a history of kidney transplantation. Cox proportional hazards models determined the effect of gout on all-cause mortality, controlling for confounders, including comorbid mortality risk, via the Charlson Comorbidity Index. Because the relationships between gout and components of the Charlson Comorbidity Index are also debated, 3 different model assumptions were used: 1) gout shares a common cause with these comorbidities, 2) gout is upstream of these comorbidities, 3) the effect of gout on mortality is modified by these comorbidities. RESULTS Gout increased the risk of all-cause mortality in the unadjusted model (hazard ratio: 1.44, 95% CI 1.27-1.63) and after adjustment for demographics and transplant vintage (hazard ratio: 1.16, 95% CI 1.02-1.32). Gout was not a significant risk after adjustment for baseline Charlson Comorbidity Index (hazard ratio: 1.03, 95% CI 0.90-1.17). Gout was associated with greater mortality among patients without baseline comorbidities (Charlson Comorbidity Index=0; hazard ratio: 3.48, 95% CI 1.27-9.57) in the stratified model. CONCLUSIONS Among patients with a history of kidney transplantation, gout did not have an independent effect on all-cause mortality. However, gout was a predictor of mortality among patients with no comorbidities, suggesting that gout is an early warning sign of poor health in kidney transplantation patients.

Hypoactive sexual desire disorder (HSDD) is not "female erectile dysfunction (ED)": challenges with the characterization of HSDD in women based on a systematic literature review.

Objective: Hypoactive sexual desire disorder (HSDD) in women has been viewed inaccurately by some in the medical and payer community as analogous to erectile dysfunction (ED) in men. This literature review aims to highlight the distinctions between HSDD and ED.Methods: Two systematic literature searches were conducted on the epidemiology, symptomatology and biopsychosocial outcomes of HSDD and ED. Studies published since 2007 were considered for HSDD; studies published since 2012 were considered for ED.Results: HSDD in women is primarily a central nervous system condition related to neuroendocrine factors, whereby neural pathways that regulate sexual excitation and/or inhibition appear to be involved. A combination of organic and psychogenic factors often contributes to ED. HSDD and ED are associated with similar psychological and interpersonal consequences, but affect different phases of the sexual response model (desire versus arousal) and have different pathophysiologies, therefore requiring different treatment and outcome paradigms. ED is measured by objective, physiological responses (erection and sexual function), but quantitative assessments for HSDD are more difficult because loss of desire with associated distress has to be assessed. Outcome measures used to assess ED, such as the number of satisfying sexual events, are far less informative as an endpoint for randomized clinical trials of treatments for HSDD.Conclusions: HSDD and ED are distinct conditions affecting different phases of the sexual response model, and thus require clear and unique clinical characterization and adequate communication between the health care professional and patient for appropriate diagnosis, management and treatment.

Hypophosphatemia Associated with Intravenous Iron Therapies for Iron Deficiency Anemia: A Systematic Literature Review.

BACKGROUND: Iron deficiency anemia (IDA) is a prevalent yet underdiagnosed condition with a significant impact on quality of life. Oral iron supplementation is often poorly tolerated or yields inadequate response, requiring the use of intravenous iron (IVI) in some patients. Administration of certain IVI preparations has been associated with decreases in serum phosphate levels and clinically significant hypophosphatemia, which has been reported to lead to adverse events including serious fatigue and osteomalacia. OBJECTIVE: The purpose of this study was to systematically assess the prevalence, clinical consequences, and reporting of treatment-emergent hypophosphatemia within literature investigating IVI therapies marketed in the United States (US). METHODS: A systematic literature review (SLR) was conducted using the PubMed database to identify publications reporting serum phosphate levels or rates of hypophosphatemia within adult IDA patient populations receiving current US-marketed IVIs. RESULTS: The SLR yielded 511 unique publications, with 40 records meeting the final inclusion criteria. Most studies did not report phosphate monitoring methodology or an explicit definition of hypophosphatemia. Hypophosphatemia rates ranged from 0.0% to 92.1% for ferric carboxymaltose (FCM), 0.0% to 40.0% for iron sucrose, 0.4% for ferumoxytol, and 0.0% for low-molecular-weight (LMW) iron dextran. Randomized controlled studies described hypophosphatemia as "asymptomatic" or did not report on other associated sequelae. Eleven case reports detailed treatment-emergent hypophosphatemia in patients treated with FCM. Patients with acute hypophosphatemia primarily developed severe fatigue; those with repeated FCM dosing developed chronic hypophosphatemia associated with osteomalacia and bone deformities. CONCLUSION: Studies analyzed in this SLR reported a range of hypophosphatemia rates, with the highest consistently seen in patients treated with FCM. Across the clinical literature, there appeared to be minimal standardization of phosphate monitoring and definitions of hypophosphatemia. Although multiple cases have documented serious clinical consequences of hypophosphatemia associated with certain IVIs, current trials neither consistently nor adequately assess the frequency and severity of treatment-emergent hypophosphatemia and may underestimate its prevalence.

Immunosuppressant Use and Gout in the Prevalent Solid Organ Transplantation Population.

INTRODUCTION: Gout is a common comorbidity among solid organ transplantation patients and is usually attributed to the use of cyclosporine. This study aims to evaluate the prevalence of gout among solid organ transplantation patients to determine the prevalence in the tacrolimus era. RESEARCH QUESTIONS: To what degree is cyclosporine still used among prevalent solid organ transplantation patients? How prevalent is gout in the solid organ transplantation population not being treated by cyclosporine? METHODS: Immunosuppressant regimens and gout prevalence among prevalent solid organ transplantation patients were assessed using retrospective claims data for a representative sample of commercially insured patients. For comparison to the prevalent solid organ transplantation population, immunosuppressant use at time of transplantation was compiled from published reports. RESULTS: Between 2012 and 2016, the use of cyclosporine declined while use of tacrolimus increased, with greater cyclosporine use among prevalent versus incident solid organ transplantation patients. The prevalence of gout was 18.3%, 9.3%, and 9.1% for solid organ transplantation patients on cyclosporine, tacrolimus, and neither, respectively. Among all solid organ transplantation patients with gout, 66.6% and 21.5% were on tacrolimus versus cyclosporine. The prevalence of gout among noncyclosporine solid organ transplantation patients was significantly higher than in the general population without solid organ transplantation. DISCUSSION: Despite declining cyclosporine use, gout prevalence remains high, with the majority of patients with gout receiving tacrolimus rather than cyclosporine. In summary, gout remains a frequent comorbidity of solid organ transplantation.

Prevalence of Gout in the Surviving United States Solid Organ Transplantation Population.

PURPOSE: Although incidence and survival are frequent topics within the solid organ transplantation (SOT) literature, the size of the surviving SOT population is not well known. Existing studies of gout in patients with SOT have focused on the incident SOT population. This analysis was performed to characterize the prevalent SOT population and the prevalence of gout within it. METHODS: This study includes the 2017 United States (US) population size of recipients of kidney, heart, liver, and lung transplants that was estimated by combining primary transplant recipient cohort sizes (1988-2017) with previously published survival rates for each annual cohort's time since transplantation (0-29 years). Gout among prevalent patients with SOT was assessed using Medicare and commercial claims. RESULTS: A total of 637,231 US patients received a primary kidney (393,953), liver (142,186), heart (66,637), or lung (34,455) transplant between 1988 and 2017. An estimated 356,000 (55.8%) recipients were alive in 2017 (233,000 kidney; 78,700 liver; 29,300 heart; 14,700 lung). Gout was identified in 11% of prevalent patients with SOT in 2016. Higher rates of gout were seen in recipients of kidney (13.1%) and heart (12.7%) compared to recipients of liver (6.7%) and lung (5.6%) (P < .0001 in both datasets). Active diagnosed gout prevalence in the US population without a SOT history was 1.1% in 2016. CONCLUSIONS: Hundreds of thousands of US patients are living with a transplanted organ today and these numbers are likely to increase. In patients with SOT, gout is a frequent comorbidity of which physicians should be aware. This study suggests a markedly higher rate of gout among transplant recipients compared to the general US population.

A patient-reported, non-interventional, cross-sectional discrete choice experiment to determine treatment attribute preferences in treatment-naïve overactive bladder patients in the US.

PURPOSE: Many pharmacotherapeutic treatment options are available for the symptoms of overactive bladder (OAB), each offering varying efficacy, safety, and tolerability profiles that must be carefully considered when selecting treatment. The objective of the present study was to characterize pharmacotherapy treatment preferences of individuals with symptoms of OAB and to examine how preferences differ by both patient characteristics and disease burden metrics. PATIENTS AND METHODS: Patient preferences for OAB treatment attributes were examined using a discrete choice experiment (DCE). Attributes were identified through literature review, clinical relevance, and input from patients. Eligible respondents were required to be ≥18 years of age, have a self-reported physician OAB diagnosis or have self-reported symptoms of OAB, and be naïve to pharmacotherapy or invasive OAB treatments. A hierarchical Bayesian random-effects-only model was used to estimate the mean relative preference weights and mean relative importance scores of treatment attributes. Multivariable linear regression models with backward selection were used to analyze the differences in relative importance scores by demographic characteristics and disease burden-related metrics. RESULTS: In total, 514 individuals participated in the study. Most respondents were <65 years of age (66.0%), female (68.5%), and reported moderate/severe OAB symptoms (64.2%). Overall, respondents placed the greatest importance on drug delivery method, with a preference for oral and patches over injectables, followed by efficacy defined as reduced daytime micturition and out-of-pocket cost. Multivariable linear regression analyses revealed that females were less likely to select injectables, that symptom control of incontinence was the most important to respondents who reported greater work productivity loss, and that out-of-pocket cost was the most important to respondents with moderate/severe OAB. CONCLUSION: OAB treatment preferences vary depending on individual patient characteristics and disease severity. Overall, drug delivery method, reduced daytime micturition, and out-of-pocket costs were the most important treatment attributes among treatment-naïve individuals with symptoms of OAB. Preferences for OAB treatment were also found to vary depending on patient demographics and disease comorbidities, which has previously not been examined.

Dermatologist and Patient Preferences in Choosing Treatments for Moderate to Severe Psoriasis.

INTRODUCTION: The objective of the study was to determine the relative importance (RI) of treatment attributes psoriasis patients and physicians consider when choosing between biologic therapies based on psoriasis severity. METHODS: A discrete choice experiment (DCE) weighting preference for eight sets of hypothetical treatments for moderate or severe psoriasis was conducted. DCE hypothetical treatments were defined and varied on combinations of efficacy, safety, and dosing attributes [frequency/setting/route of administration (ROA)]. RESULTS: When assuming moderate psoriasis in the patient DCE, ROA (RI 29%) and efficacy (RI 27%) drive treatment choices. When assuming severe disease in the DCE, patients preferred treatments with higher efficacy (RI 36%); ROA was relatively less important (RI 15%). From the physician perspective, ROA (RI 32%) and efficacy (RI 26%) were most important for moderate psoriasis patients. In the physician model for severe psoriasis, efficacy (RI 42%) was the predominant driver followed by ROA (RI 22%). Regardless of severity, probability of loss of response within 1 year was the least important factor. CONCLUSIONS: The severity of disease is a critical element in psoriasis treatment selection. There are high levels of alignment between physician- and patient-derived preferences in biologic treatment choice selection for psoriasis. FUNDING: Janssen Pharmaceuticals.

Understanding the burden of illness associated with hypoparathyroidism reported among patients in the PARADOX study.

OBJECTIVE: Hypoparathyroidism is a rare disease caused by lack of parathyroid hormone (PTH) leading to hypocalcemia, hyperphosphatemia, and a variety of symptoms. This study aimed to quantify the clinical and social burden of illness from the perspective of affected patients. METHODS: A web-based instrument was developed with input from patients, clinical experts, and the Hypoparathyroidism Association. Qualifying participants were ≥18 years old, diagnosed with hypoparathyroidism for ≥6 months, and U.S. residents. Questions focused on demographics, diagnosis perceptions, current attitudes, medical management, current symptoms, acute episodes, comorbidities, personal life, and employment. RESULTS: A total of 374 adults (mean age, 49 ± 12 years; female, 85%) with hypoparathyroidism (mean duration, 13 ± 12 years; severe condition, 30.5%) completed the survey. Patients reported visiting a mean of 6 ± 8 physicians before and after their diagnosis. The majority strongly agreed with feeling unprepared to manage the condition at diagnosis (56%), that controlling their hypoparathyroidism is harder than expected (60%), and that they were concerned about long-term complications of their current medications (75%). More than 10 symptoms were experienced by 72% of patients in the preceding 12 months, despite current management regimens. Symptoms were experienced for a mean of 13 ± 9 hours/day. Hospital stays or emergency department visits were required by 79% of patients. 45% reported significant interference with their lives, 85% reported an inability to perform household activities, and 20% experienced a disease-associated change in employment status. CONCLUSION: Patients with hypoparathyroidism have a high burden of illness and experience a broad spectrum of symptoms, with a multidimensional impact on their lives.

Are there financial savings associated with supplementing current diagnostic practice for preeclampsia with a novel test? Learnings from a modeling analysis from a German payer perspective.

OBJECTIVE: To quantify the financial impact of adding a novel serum test to the current diagnostic toolkit for preeclampsia (PE) detection in Germany. METHODS: A decision-analytic model was created to quantify the economic impact of adding a recently developed novel diagnostic test for PE (Roche Diagnostics, Rotkreuz, Switzerland) to current diagnostic practice in Germany. The model simulated a cohort of 1000 pregnant patients receiving obstetric care and quantified the budget impact of adding the novel test to current German PE detection and management practices. RESULTS: The model estimates that the costs associated with managing a typical pregnancy in Germany are €941 when the novel test is used versus €1579 with standard practice. This represents savings of €637 per pregnant woman, even when the test is used as a supplementary diagnostic tool. The savings are attributed to the novel test's ability to better classify patients relative to current practice, specifically, its ability to reduce false negatives by 67% and false positives by 71%. CONCLUSION: The novel PE test has the potential to provide substantial cost savings to German healthcare payers, even when used as an addition to standard practice. Better classification of patients at risk for developing PE and declassification of those that are not compared to current practice leads to economic savings for the healthcare system. Furthermore, by reducing the rates of false-positive and false-negative classification relative to current standard of care, the test helps better target healthcare spending and lowers overall costs associated with PE care.

The impact of a patient support program for multiple sclerosis on patient satisfaction and subjective health status.

BACKGROUND: Leading multiple sclerosis (MS) therapies have patient support programs (PSPs) aimed at improving patients' lives. There is limited knowledge about what drives patient satisfaction with PSPs and little evidence about its impact on patient-reported health status or health-related quality of life. OBJECTIVE: The aims of this study were to evaluate patient needs and the PSP's role in meeting those needs; understand the drivers of PSP satisfaction and loyalty; and assess whether a MS PSP provides quantifiable, incremental benefit to patients, as measured by patient-reported health status, health state utility, and/or health-related quality of life. METHODS: An Internet survey was conducted among 1,123 adult German MS patients currently enrolled in Bayer's German BETAPLUS PSP. Health status, health state utility, and health-related quality of life were measured using the EQ-5D Visual Analog Scale, the EQ-5D Index, and Short Form-12 Health Survey, respectively. RESULTS: MS patient needs vary by disease severity, duration of disease, and gender. Patients with greater self-reported needs and lower health status, health state utility, and health-related quality of life value and use the PSP more than other patients. Drivers of PSP satisfaction include use of patient hotline, nurse telephone calls, and mail education. Patients estimate that their health status would be 15 points lower if the PSP ceased to exist (translating to 0.15 on the time trade-off utility scale). This impact is significant, as it is nearly two times the minimally important difference. CONCLUSIONS: MS patients place inherent value on PSPs. From a patient's viewpoint, PSPs provide real incremental benefit in patient-reported health status at all stages of MS.

Nurse workload in implementing a tight glycaemic control protocol in a UK hospital: a pilot time-in-motion study.

AIMS AND OBJECTIVES: The cumulative time that critical care nurses spend implementing a tight glycaemic control (TGC) protocol was estimated in a time-in-motion (TiM) study conducted in a hospital in the UK. BACKGROUND: TGC protocols were introduced to the critical care setting to reduce hyperglycaemic events in high-risk patients. The time burden to critical care nurses of implementing such protocols has not yet been studied in the UK. DESIGN: A prospective TiM pilot study was conducted in an eligible UK intensive care unit by four protocol-trained observers over five consecutive weekdays from 3 to 7 November 2008. Three nurses were also interviewed on site to gather their attitudes and perceptions about the benefits of and time associated with administering a TGC protocol. METHODS: Independent observers shadowed nurses, observing when a blood glucose measurement was taken, when each predefined subtask was completed and the duration of each task. Semistructured interviews with nurses were conducted in-person and one-on-one by a trained study member. RESULTS: Considered together, the episodic median duration of all TGC activities was 6·65 min. Across a total shift, nurses devoted approximately 7% of their time to administering a TGC protocol. Nurses perceived that a TGC protocol is beneficial to patient safety and outcomes in a critical care setting but acknowledged that the tasks can be mildly to moderately tedious. CONCLUSIONS: This TiM analysis indicated that the additional responsibility of implementing a TGC protocol represents a substantive commitment of nursing time in a critical care setting. RELEVANCE TO CLINICAL PRACTICE: The episodic data of our pilot study in the UK contributes further evidence that TGC protocols may be arduous to maintain and constitute a substantial investment of nursing time.

A literature review of the feasibility of glial fibrillary acidic protein as a biomarker for stroke and traumatic brain injury.

Traumatic brain injuries (TBIs) are potentially lethal medical conditions, with symptoms that can overlap with symptoms of injuries outside the brain. In many cases, current diagnostic methods do not fully distinguish acute brain injury from other organ damage. In the management of stroke patients, the choice of treatment depends on whether the stroke is ischemic or hemorrhagic; however, no quick lab diagnostic tests are available to distinguish between the two types of strokes. As a result, patient triage, disposition, and patient management decisions may be delayed for patients with suspected TBI and stroke. Glial fibrillary acidic protein (GFAP), a brain-specific biomarker that is released into the blood following TBI and stroke, is being explored for potential diagnostic and prognostic value in these indications. We therefore conducted a review of MEDLINE-indexed publications from 2004 to 2011 to evaluate the current status of GFAP as a prognostic and diagnostic tool for TBI and stroke within the context of current published guidelines. Our review suggests that GFAP could provide clinically valuable information for the prognosis of TBI and stroke, but it is still at an early stage of development as a biomarker. Several TBI studies have shown elevated GFAP levels following a TBI event to be associated with greater severity of injury, poorer outcomes, and increased mortality. Clinical studies also indicate that GFAP has potential clinical utility in the differential diagnosis of various types of stroke. However, more clinical research will be required to determine the ability of GFAP levels to diagnose TBI in heterogeneous patient populations, as well as the ability of GFAP to differentiate between ischemic stroke (IS), intracerebral hemorrhage (ICH), subarachnoid hemorrhage (SAH), and non-stroke conditions in populations of patients with suspected rather than confirmed stroke. Additional clinical studies will also be required to define the temporal patterns of GFAP release in IS, ICH, SAH, and TBI, and their potential use in the differential diagnosis of these conditions. Finally, such research could demonstrate the ability of GFAP test results to provide unique clinical information that informs management decisions for TBI and stroke patients.

The impact of 'best-practice' patient care in fibromyalgia on practice economics.

OBJECTIVE: The office time required for primary care physicians (PCPs) to diagnose, treat and manage fibromyalgia (FM) patients can be extensive. The study objective was to determine if PCPs can positively impact practice economics by requiring fewer patient visits and less office time, while still achieving an acceptable quality of life, as reported by the physician. STUDY DESIGN: Survey of PCPs who diagnose, manage and treat FM patients. METHODS: Surveys were administered to US private practice PCPs, obtaining information on the number of office visits, and time spent with FM patients. PCPs were allotted into two groups: FM-efficient (FME; n = 40) and FM usual care (FMUC; n = 54), based on their reported ability to achieve an acceptable quality of life for ≥50% of their FM patients in less than four office visits post FM diagnosis. An economic model estimated the monetary value of each PCP cohorts' time spent with a newly diagnosed FM patient over a 2-year timeframe. RESULTS: Significant office time cost differences across 2 years exist between FME PCPs and FMUC PCPs ($840 vs. $1117, P < 0.05). FME PCPs had a significantly lower cost of scheduled time to confirm diagnosis ($243 vs. $339, P < 0.05) and time to find right treatment ($264 vs. $365, P < 0.05) than FMUC PCPs. Both groups incurred costs related to excess visit time, but it was less for FME PCPs ($119, 29 minutes) than FMUC PCPs ($182, 44 minutes, P < 0.01), driven by quicker diagnosis confirmation (P < 0.01) and treatment initiation (P < 0.01). CONCLUSIONS: Research suggests that efficient FM care delivery during diagnosis and treatment can be associated with improved practice economics.
