Background: Multiple sclerosis (MS) is a chronic progressive condition affecting the central nervous system. Progression of MS results in increased level of disability and most patients will eventually experience some degree of functional impairment and impaired mobility. Costs and burdens escalate as MS disability increases. However, there is a lack of recent data on the impact of MS disability on the cost and burden among patients in the US.Methods: Data for this study were drawn from a real world, cross-sectional survey undertaken between 2013 and 2014. Neurologists completed detailed patient report forms (PRF) for the most recent consulting patients with MS (age >18 years). Patient's perceptions of their diagnosis and health-related quality of life (HRQoL) were collected through a patient self-completion questionnaire (PSC). Regression analysis was used to evaluate the relationship between disability (determined by latest Expanded Disability Status Scale [EDSS] score) and current relapse and health care resource utilization, health care costs, HRQoL and work productivity.Results: PRF data were collected for 715 patients (335 also completed a PSC). Patients with higher disability scores (EDSS 3-5 and >5 vs <3 points) and current relapse (vs no current relapse) reported significantly greater health resource utilization for physician visits (p < 0.05) and hospitalizations (p < 0.05) in the preceding 12 months. In addition, they had poorer HRQoL (p < 0.05), were significantly more likely to be unemployed (p < 0.05) and to have had to stop working due to MS (p < 0.05). They also incurred significantly higher health care related costs, including costs for physician consultations, hospitalizations and therapy (p < 0.05). The total costs of care were $51,825, $57,889 and $67,116 for EDSS < 3, EDSS 3-5 and EDSS > 5 groups, respectively; $51,692 and $58,648 for non-relapse and relapse groups, respectively.Conclusions: For MS patients in the US, health resource utilization and healthcare care costs increase with progression of disability. As the disability worsens, patients also exhibit diminished HRQoL and lower work productivity. There is a need for treatments that slow down or delay disability progression among MS patients.

Background and Objectives: Respiratory syncytial virus (RSV) causes substantial hospitalization in US infants. The Advisory Committee on Immunization Practices recommended nirsevimab in infants younger than 8 months born during or entering their first RSV season and for children aged 8 to 19 months at increased risk of RSV hospitalization in their second season. This study's objective was to evaluate the cost-effectiveness of nirsevimab in all infants in their first RSV season and in high-risk children in their second season., Methods: We simulated healthcare utilization and deaths from RSV with and without nirsevimab among infants aged 0 to 7 months and those 8 to 19 months old over a single RSV season. Data came from published literature, US Food and Drug Administration approval documents, and epidemiologic surveillance data. We evaluated societal outcomes over a lifetime discounting at 3% and reporting in 2022 US dollars. Sensitivity and scenario analyses identified influential variables., Results: We estimated that 107 253 outpatient visits, 38 204 emergency department visits, and 14 341 hospitalizations could be averted each year if half of the US birth cohort receives nirsevimab. This would cost $153 517 per quality-adjusted life year (QALY) saved. Nirsevimab in the second season for children facing a 10-fold higher risk of hospitalization would cost $308 468 per QALY saved. Sensitivity analyses showed RSV hospitalization costs, nirsevimab cost, and QALYs lost from RSV disease were the most influential parameters with cost-effectiveness ratios between cost-saving and $323 788 per QALY saved., Conclusions: Nirsevimab for infants may be cost-effective, particularly among those with higher risks and costs of RSV., (Copyright © 2024 by the American Academy of Pediatrics.)

Background and Objectives: Respiratory syncytial virus (RSV) commonly causes hospitalization among US infants. A maternal vaccine preventing RSV in infants, RSV bivalent prefusion F maternal vaccine (RSVpreF), was approved by the US Food and Drug Administration and recommended by the Advisory Committee on Immunization Practices. Our objective was to evaluate the health benefits and cost-effectiveness of vaccinating pregnant persons in the United States using RSVpreF., Methods: We simulated RSV infection and disease with and without seasonal RSVpreF vaccination in half of the pregnant persons in the annual US birth cohort during weeks 32 through 36 of gestation. Model inputs came from peer-reviewed literature, Food and Drug Administration records, and epidemiological surveillance databases. The results are reported using a societal perspective in 2022 US dollars for a 1-year time frame, discounting future health outcomes and costs at 3%. Sensitivity and scenario analyses were performed., Results: Year-round maternal vaccination with RSVpreF would prevent 45 693 outpatient visits, 15 866 ED visits, and 7571 hospitalizations among infants each year. Vaccination had a societal incremental cost of $396 280 per quality-adjusted life-year (QALY) saved. Vaccination from September through January cost $163 513 per QALY saved. The most influential inputs were QALYs lost from RSV disease, the cost of the vaccine, and RSV-associated hospitalization costs; changes in these inputs yielded outcomes ranging from cost-saving to $800 000 per QALY saved., Conclusions: Seasonal maternal RSV vaccination designed to prevent RSV lower respiratory tract infection in infants may be cost-effective, particularly if administered to pregnant persons immediately before or at the beginning of the RSV season., (Copyright © 2024 by the American Academy of Pediatrics.)

Respiratory syncytial virus (RSV) causes substantial morbidity and mortality in older adults. In May 2023, two subunit RSV vaccines (Arexvy [GSK] and Abrysvo [Pfizer]) received approval from the U.S. Food and Drug Administration (FDA). In June 2023, ACIP recommended that adults aged ≥60 years may receive a single dose of RSV vaccine, using shared clinical decision-making. In support of development of this policy, our objective was to assess the cost-effectiveness of RSV vaccination in the general population in this age group. We used a decision-analytical model of RSV over a two-year timeframe using data from published literature, FDA documents, epidemiological databases, and manufacturer data. We tracked RSV-associated outpatient, emergency department, inpatient healthcare utilization, RSV-attributable deaths, quality-adjusted life-years lost (QALYs), and societal costs. The societal cost per QALY saved from RSV vaccination depended on age group and product: adults aged ≥60 years, $196,842 for GSK's vaccine and $176,557 for Pfizer's vaccine; adults ≥65 years, $162,138 for GSK and $146,543 for Pfizer; adults 60- <65 years, $385,829 for GSK and $331,486 for Pfizer. Vaccine efficacy, incidence of RSV hospitalization, and vaccine cost had the greatest influence on cost per QALY. Cost per QALY saved decreased as the age of those vaccinated increased. Inputs such as long-term efficacy are uncertain. RSV vaccination in adults aged ≥60 years may be cost-effective, particularly in those of more advanced age. Lower vaccine acquisition costs and persistent efficacy beyond two RSV seasons would render RSV vaccination more cost-effective for a broader target population.

This study aimed to quantify U.S. jurisdiction-level costs related to the COVID-19 Vaccination Program by estimating the per-dose-administered cost during December 20, 2020-May 31, 2021, from a combined federal and local government perspective. Costs were limited to vaccine purchase, administration (including operations and wastage), and local redistribution by jurisdictions. Data were collected through publicly available sources, published literature, and a survey of 62 jurisdictions (38 responded). A total of 284.6 million doses of COVID-19 vaccine were distributed to jurisdictions during the study period, of which 284.2 million doses were administered, and 0.4 million doses were wasted. The estimated cost per-dose-administered among the 38 jurisdictions that responded to study survey was $57.45 and imputed cost across all jurisdictions was $63.11. The findings on jurisdiction-level cost per-dose-administered and vaccination cost during the initial period of U.S. COVID-19 Vaccination Program, when demand exceeded supply, may be considered in future pandemic preparedness planning., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024.

In 1994, the World Health Organization Region of the Americas was declared polio-free. In July 2022, a confirmed case of paralytic polio in an unvaccinated adult resident of Rockland County, New York was reported by the New York State Department of Health (NYSDOH) and Rockland County Department of Health (RCDOH). While only one case was identified, a single case of paralytic polio represents a public health emergency in the United States. The patient's county of residence was identified to have low vaccination coverage indicating that the community was at risk for additional cases. Disease outbreaks are resource-intensive and incur high costs to the patient, local health departments, and to society. These costs are potentially avoidable for vaccine-preventable diseases and thus, highlight the urgency to not only interrupt transmission but to prevent future vaccine-preventable disease outbreaks by improving vaccination coverage. Following case confirmation, an investigation and response was initiated by NYSDOH, along with local health departments and the Centers for Disease Control and Prevention (CDC). After the initial investigation and response, collaborative efforts to mitigate risk and strengthen routine immunization continued, which included provider outreach and immunization record assessments of Head Start and licensed childcare facilities (primarily those with missing or incomplete required vaccination coverage reports from the previous year) in Rockland County. We estimated the costs of (1) provider outreach and (2) childcare and pre-kindergarten immunization record assessments of select licensed childcare and Head Start facilities in Rockland County. The total labor cost incurred for these activities was $138,514 with a total of 2,555 h incurred. Often there are unique opportunities in the midst of an outbreak for public health to implement activities to proactively address low vaccination and strengthen vaccination coverage and possibly prevent future outbreaks. Understanding the cost of these activities might help inform future outbreak planning., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Published by Elsevier Ltd.)

Introduction: Part of the difficulty in recruiting and retaining a diverse physician workforce, as well as within medical leadership, is due to racial disparities in medical education. We investigated whether self-identified race-ethnicity is associated with the likelihood of selection as chief resident (CR)., Materials and Methods: We performed a cross sectional analysis using de-identified person-level data from the GME Track, a national resident database and tracking system, from 2015 through 2018. The exposure variable, self-identified race-ethnicity, was categorized as African American or Black, American Indian or Alaskan Native, Asian, Hispanic, Latino or of Spanish Origin, Native Hawaiian or Pacific Islander, White, and Multi-racial. The primary study outcome was CR selection among respondents in their final program year. Logistic regression was used to estimate the adjusted odds ratios (aOR) and 95% confidence intervals (CI) of CR selection for each racial group, as compared to the White referent group., Results: Among the study population (N=121,247), Black, Asian and Hispanic race-ethnicity was associated with a significantly decreased odds of being selected as CR in unadjusted and adjusted analyses. Black, Asian and Hispanic residents had a 26% (aOR=0.74, 95% CI 0.66-0.83), 29% (aOR=0.71, 95% CI 0.66-0.76) and 28% (aOR=0.72, 95% CI 0.66-0.94) decreased likelihood of becoming CR, respectively. Multi-racial residents also had a decreased likelihood, but to a lesser degree (aOR=0.92, 95% CI 0.89-0.95)., Conclusions: In as much as CR is an honor that sets one up for future opportunity, our findings suggest that residents of color are disproportionately disadvantaged compared to their White peers., (Copyright © 2023 National Medical Association.

Background: Despite the known benefits of breastfeeding to infants and mothers, previous studies have demonstrated that underserved women are less likely to exclusively breastfeed. Existing studies on the impact of Special Supplemental Nutritional Program for Women, Infants, and Children enrollment on feeding decisions for infants have conflicting results with low-quality data and metrics., Objective: This study aimed to examine infant feeding trends nationally in the first week postpartum over a 10-year period, comparing breastfeeding rates for primiparous women with low income who used Special Supplemental Nutritional Program for Women, Infants, and Children resources with those women who did not enroll. We hypothesized that although the Special Supplemental Nutritional Program for Women, Infants, and Children is an important resource for new mothers, free formula associated with enrollment in the Special Supplemental Nutritional Program for Women, Infants, and Children may disincentivize women to exclusively breastfeed., Study Design: This was a retrospective cohort study of primiparous women with singleton gestations who gave birth at term and who responded to the Centers for Disease Control and Prevention Pregnancy Risk Assessment Monitoring System between 2009 and 2018. Data were extracted from phases 6, 7, and 8 of the survey. Women with low income were defined as those with a reported annual household income of $35,000 or less. The primary outcome was exclusive breastfeeding after 1 week postpartum. Secondary outcomes included ever breastfeeding, any breastfeeding after 1 week postpartum, and introduction of other liquids within 1 week postpartum. Multivariable logistic regression was used to refine risk estimates with adjustment for mode of delivery, household size, education level, insurance status, diabetes, hypertension, race, age, and BMI., Results: Among the 42,778 women with low income who were identified, 29,289 (68%) of these women reported receiving Special Supplemental Nutritional Program for Women, Infants, and Children resources. There was no significant difference in the rates of exclusive breastfeeding after 1 week postpartum between those enrolled in the Special Supplemental Nutritional Program for Women, Infants, and Children and those not enrolled (adjusted risk ratio, 1.04; 95% confidence interval, 1.00-1.07; P=.10). However, those enrolled were less likely to ever breastfeed (adjusted risk ratio, 0.95; 95% confidence interval, 0.94-0.95; P<.01) and were more likely to introduce other liquids within 1 week postpartum (adjusted risk ratio, 1.16; 95% confidence interval, 1.11-1.21; P<.01)., Conclusion: Although exclusive breastfeeding rates after 1 week postpartum were similar, women enrolled in the Special Supplemental Nutritional Program for Women, Infants, and Children were significantly less likely to ever breastfeed and more likely to introduce formula within the first week postpartum. This suggests that Special Supplemental Nutritional Program for Women, Infants, and Children enrollment may impact the decision to initiate breastfeeding and may represent an important window to test future interventions., (Copyright © 2023 Elsevier Inc.

Background: Racial and ethnically minoritized individuals and women are underrepresented in leadership roles in academic medicine. Little is known about whether and to what extent these racial and sex disparities exist in graduate medical education., Objective: This study aimed to determine whether race-ethnicity or the intersection of race-ethnicity and sex impact the likelihood of being selected as chief resident in obstetrics and gynecology residency programs., Study Design: We performed cross-sectional analyses using data from Graduate Medical Education Track, a national resident database and tracking system. Those included in this analysis were final-year obstetrics and gynecology residents in US-based residency programs from 2015 to 2018. The exposure variables were self-reported race-ethnicity and sex. The outcome was being selected as chief resident. A logistic regression was used to estimate the odds of being selected as chief resident. We tested the following variables for potential confounding: survey year, United States citizenship, medical school type, geographic region of residency, and Alpha Omega Alpha status., Results: There were 5128 residents included. Black residents were 21% less likely to be selected as chief resident than White residents (odds ratio, 0.79; 95% confidence interval, 0.65-0.96). Females were 19% more likely to be chief resident than males (odds ratio, 1.19; 95% confidence interval, 1.02-1.38). When examining the intersection of race-ethnicity and sex, the results revealed some heterogeneity. Among males, Black individuals had the lowest odds of being selected as chief resident (odds ratio, 0.32; 95% confidence interval, 0.17-0.63; referent White males), whereas among females, Hispanic individuals were the least likely to be selected as chief resident (odds ratio, 0.69; 95% confidence interval, 0.52-0.92; referent White females). White females were almost 4 times more likely to be selected as chief resident than Black males (odds ratio, 3.79; 95% confidence interval, 1.97-7.29)., Conclusion: The odds of being selected as chief resident differ significantly by race-ethnicity, sex, and the intersection of these factors., (Copyright © 2023 Elsevier Inc.

Introduction: Sociodemographic factors and chronic conditions associated with coronavirus disease 2019 (COVID-19) among persons with substance use disorder (PWSUD) are not well understood. We identified risk factors associated with COVID-19 among PWSUD with hospital visits., Methods: Using the Premier Healthcare Database Special COVID-19 Release, we conducted a case-control study using ICD-10-CM codes to identify PWSUD aged 12 years and older with hospital visits for any reason during April-December 2020. Multivariable logistic regression was used to calculate adjusted odds ratios (aOR) and 95% confidence intervals (CI) to identify factors associated with COVID-19 diagnosis among PWSUD (age, sex, race/ethnicity, U.S. Census Region, urban/rural classification, insurance payor type, comorbidities, and substance use disorder [SUD] type), and then stratified by SUD type., Results: From April-December 2020, 18,298 (1.3%) of 1,429,154 persons with SUD in the database had a COVID-19 diagnosis. Among PWSUD, opioid use disorder (OUD; aOR = 1.24, 95% CI = 1.18-1.32), alcohol use disorder (AUD; aOR = 1.16, 95% CI = 1.11-1.22), cocaine or other stimulant use disorder (COUD; aOR = 1.28, 95% CI = 1.22-1.34), and multiple SUDs (aOR = 1.20, 95% CI = 1.15-1.26) were associated with higher odds of COVID-19, as were comorbidities such as chronic lower respiratory disease (aOR = 1.32, 95% CI = 1.26-1.37), chronic hepatitis (aOR = 1.45, 95% CI = 1.34-1.57), and diabetes (aOR = 1.78, 95% CI = 1.71-1.86)., Conclusions: Among a sample of PWSUD, OUD, AUD, COUD, multiple SUDs, and associated comorbidities were associated with COVID-19 diagnosis. Integration of COVID-related care, care of other comorbidities, and SUD treatment may benefit PWSUD. Future studies are needed to better understand COVID-19 prevention in this population and to reduce disparities among subpopulations at increased risk., (Published by Elsevier B.V.)

Objective: Noroviruses are the leading cause of acute gastroenteritis in the United States and outbreaks frequently occur in daycare settings. Results of norovirus vaccine trials have been promising, however there are open questions as to whether vaccination of daycare children would be cost-effective. We investigated the incremental cost-effectiveness of a hypothetical norovirus vaccination for children in daycare settings compared to no vaccination., Methods: We conducted a model-based cost-effectiveness analysis using a disease transmission model of children attending daycare. Vaccination with a 90% coverage rate in addition to the observed standard of care (exclusion of symptomatic children from daycare) was compared to the observed standard of care. The main outcomes measures were infections and deaths averted, quality-adjusted life years (QALYs), costs, and incremental cost-effectiveness ratio (ICER). Cost-effectiveness was analyzed from a societal perspective, including medical costs to children as well as productivity losses of parents, over a two-year time horizon. Data sources included outbreak surveillance data and published literature., Results: A 50% efficacious norovirus vaccine averts 571.83 norovirus cases and 0.003 norovirus-related deaths per 10,000 children compared to the observed standard of care. A $200 norovirus vaccine that is 50% efficacious has a net cost increase of $178.10 per child and 0.025 more QALYs, resulting in an ICER of $7,028/QALY. Based on the probabilistic sensitivity analysis, we estimated that a $200 vaccination with 50% efficacy was 94.0% likely to be cost-effective at a willingness-to-pay of $100,000/QALY threshold and 95.3% likely at a $150,000/QALY threshold., Conclusion: Due to the large disease burden associated with norovirus, it is likely that vaccinating children in daycares could be cost-effective, even with modest vaccine efficacy and a high per-child cost of vaccination. Norovirus vaccination of children in daycare has a cost-effectiveness ratio similar to other commonly recommended childhood vaccines., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2021 The Authors.

SARS-CoV-2, the virus that causes coronavirus disease 2019 (COVID-19), is transmitted predominantly by respiratory droplets generated when infected persons cough, sneeze, spit, sing, talk, or breathe. CDC recommends community use of face masks to prevent transmission of SARS-CoV-2 (1). As of October 22, 2020, statewide mask mandates were in effect in 33 states and the District of Columbia (2). This study examined whether implementation of statewide mask mandates was associated with COVID-19-associated hospitalization growth rates among different age groups in 10 sites participating in the COVID-19-Associated Hospitalization Surveillance Network (COVID-NET) in states that issued statewide mask mandates during March 1-October 17, 2020. Regression analysis demonstrated that weekly hospitalization growth rates declined by 2.9 percentage points (95% confidence interval [CI] = 0.3-5.5) among adults aged 40-64 years during the first 2 weeks after implementing statewide mask mandates. After mask mandates had been implemented for ≥3 weeks, hospitalization growth rates declined by 5.5 percentage points among persons aged 18-39 years (95% CI = 0.6-10.4) and those aged 40-64 years (95% CI = 0.8-10.2). Statewide mask mandates might be associated with reductions in SARS-CoV-2 transmission and might contribute to reductions in COVID-19 hospitalization growth rates, compared with growth rates during <4 weeks before implementation of the mandate and the implementation week. Mask-wearing is a component of a multipronged strategy to decrease exposure to and transmission of SARS-CoV-2 and reduce strain on the health care system, with likely direct effects on COVID-19 morbidity and associated mortality., Competing Interests: All authors have completed and submitted the International Committee of Medical Journal Editors form for disclosure of potential conflicts of interest.

Background: Many patients with Parkinson's disease (PD) who receive carbidopa/levodopa experience symptom reemergence or worsening, or "OFF" episodes. This study assessed the association of "OFF" episodes with health-related quality of life (HRQoL)., Methods: US-specific data from the 2017 and 2019 Adelphi Real World Disease Specific Programme for PD, a real-world cross-sectional survey, were used. Neurologists provided data for 10-12 consecutive patients with PD who completed the 39-item Parkinson's Disease Questionnaire (PDQ-39) and the EuroQol 5-Dimension (EQ-5D). Data were grouped by patients who experienced "OFF" episodes versus those who did not and by average hours of daily "OFF" time. Differences between patient groups were assessed for demographics and clinical characteristics; regression analyses were used to model the relationship between HRQoL and "OFF" episodes with age, sex, body mass index, current PD stage on the Hoehn and Yahr scale, and number of concomitant conditions related and unrelated to mobility as covariates., Results: Data from 722 patients were analyzed. Overall, 321 patients (44%) had "OFF" episodes (mean of 2.9 h of daily "OFF" time). Patients who experienced "OFF" episodes were less likely to work full-time and more likely to live with family members other than their spouse/partner or reside in a long-term care facility than those without "OFF" episodes. The presence of "OFF" episodes, regardless of the average hours of daily "OFF" time, was significantly associated with high scores (reflecting poor HRQoL) on most PDQ-39 dimensions and the summary index and low scores (reflecting poor health status) on the EQ-5D health utility index, visual analog scale (VAS), and all dimensions. Furthermore, increased average hours of daily "OFF" time was significantly correlated with higher scores for all PDQ-39 dimensions and the summary index, as well as with the EQ-5D health utility index and VAS scores. Patients with "OFF" episodes experienced reduced HRQoL even after correcting for potentially confounding variables., Conclusions: This study demonstrated that the occurrence of "OFF" episodes in patients with PD is associated with reduced HRQoL and that the impact on HRQoL increased incrementally with increasing average hours of daily "OFF" time.

Aims: Within 5 years of initiating carbidopa/levodopa, ∼50% of patients with Parkinson's disease (PD) experience "OFF" episodes; little is known about the cost burden. We investigated the association of "OFF" episodes with patient characteristics, healthcare resource utilization (HCRU), and healthcare costs., Methods: Analyses used neurologist-provided data from the US-specific 2017 and 2019 Adelphi Real World Disease Specific Programme for PD, including duration of "OFF" episodes and HCRU for 10-12 consecutive patients. Patients were grouped by presence/absence of "OFF" episodes and by average hours of daily "OFF" time. Between-group differences were assessed for demographics, personal circumstances, and clinical characteristics. Regression analyses modeled the relationship of "OFF" episodes with HCRU and costs., Results: Of 1,309 patients, 41% experienced "OFF" episodes, 25% of whom were "OFF" ≥4 h/day. Patients having "OFF" episodes had more severe PD, were diagnosed for longer, and were younger than those without "OFF" ( p  < .0001). "OFF" episodes were associated with a greater number of prescribed PD drugs ( p  < .0001). Patients without "OFF" episodes were more likely to have full-time employment and less likely to be retired or unemployed because of PD ( p  < .001). Patients with and without "OFF" episodes had different living situations ( p  < .001): patients experiencing "OFF" were less likely to live alone and more likely to live in a nursing home and have a professional caregiver ( p  < .001). In the past 12 months, the number of hospitalizations, intensive care admissions, and emergency room visits; nights hospitalized; costs of consultations and hospitalizations; and total direct costs were all higher for patients experiencing "OFF" episodes ( p  < .05)., Conclusion: Patients with PD and "OFF" episodes had higher HCRU and costs than those without "OFF," suggesting that "OFF" episodes contribute to the economic burden of PD. Further research is warranted to examine the extent that current PD treatments and treatment patterns impact HCRU and costs.

Background: Dementia is commonly accompanied by neurobehavioral symptoms; however, the relationship between such symptoms and health-related outcomes is unclear., Objective: To investigate the impact of specific neurobehavioral symptoms in dementia on healthcare resource use (HCRU), patient quality of life (QoL), and caregiver burden., Methods: Data were taken from the 2015/16 Adelphi Real World Dementia Disease Specific Programme™, a point-in-time survey of physicians and their consulting dementia patients. Multiple regression analyses were used to examine associations between patient symptom groups and health-related outcomes., Results: Each patient symptom group of interest (patients with agitation/aggression and related symptoms [AARS] with psychosis, patients with AARS without psychosis, and patients with other behavioral symptoms) had a positive association with HCRU variables (i.e., HCRU was greater), a negative association with proxy measures of patient QoL (i.e., QoL was decreased), and a positive association with caregiver burden (i.e., burden was greater) compared with patients with no behavioral symptoms (control group). The magnitude of effect was generally greatest in patients with AARS with psychosis. Regression analysis covariates that were found to be most often significantly related to the outcomes were dementia severity and the patients' living situation (i.e., whether they were in nursing homes or living in the community)., Conclusion: Combinations of behavioral symptoms, particularly involving AARS plus psychosis, may have a detrimental impact on health-related outcomes such as HCRU, patient QoL, and caregiver burden in dementia. Our results have implications for intervention development in patients who report clusters of symptoms and caregivers, and for identifying at-risk individuals.

Despite the elimination of measles in the United States (US) in the year 2000, cases continue to occur, with measles outbreaks having occurred in various jurisdictions in the US in 2018 and 2019. Understanding the cost associated with measles outbreaks can inform cost-of-illness and cost-effectiveness studies of measles and measles prevention. We performed a literature review and identified 10 published studies from 2001 through 2018 that presented cost estimates from 11 measles outbreaks. The median total cost per measles outbreak was $152 308 (range, $9862-$1 063 936); the median cost per case was $32 805 (range, $7396-$76 154) and the median cost per contact was $223 (range, $81-$746). There were limited data on direct and indirect costs associated with measles. These findings highlight how costly measles outbreaks can be, the value of this information for public health department budgeting, and the importance of more broadly documenting the cost of measles outbreaks., (Published by Oxford University Press for the Infectious Diseases Society of America 2020.)

Objectives: To identify the most important reasons underlying decisions to stock or not stock adult vaccines., Study Design: US physicians, nurses, pharmacists, and administrators of internal medicine, family medicine, obstetrics/gynecology, and multispecialty practices who were involved in vaccine stocking decisions (N = 125) completed a best-worst scaling survey online between February and April 2018., Methods: Sixteen potential factors influencing stocking decisions were developed based on key informant interviews and focus groups. Respondents selected factors that were most and least important in vaccine stocking decisions. Relative importance scores for the best-worst scaling factors were calculated. Survey respondents described which vaccines their practice stocks and reasons for not stocking specific vaccines. Subgroup analyses were performed based on the respondent's involvement in vaccine decision making, role in the organization, specialty, and affiliation status, as well as practice characteristics such as practice size, insurance mix, and patient age mix., Results: Relative importance scores for stocking vaccines were highest for "cost of purchasing vaccine stock," "expense of maintaining vaccine inventory," and "lack of adequate reimbursement for vaccine acquisition and administration." Most respondents (97%) stocked influenza vaccines, but stocking rates of other vaccines varied from 39% (meningococcal B) to 83% (tetanus-diphtheria-pertussis). Best-worst scaling results were consistent across respondent subgroups, although the range of vaccine types stocked differed by practice type., Conclusions: Economic factors associated with the purchase and maintenance of vaccine inventory and inadequate reimbursement for vaccination services were the most important to decision makers when considering whether to stock or not stock vaccines for adults.

Background: Provider concern regarding insurance non-payment for vaccines is a common barrier to provision of adult immunizations. We examined current adult vaccination billing and payment associated with two managed care populations to identify reasons for non-payment of immunization insurance claims., Methods: We assessed administrative data from 2014 to 2015 from Blue Care Network of Michigan, a nonprofit health maintenance organization, and Blue Cross Complete of Michigan, a Medicaid managed care plan, to determine rates of and reasons for non-payment of adult vaccination claims across patient-care settings, insurance plans, and vaccine types. We compared commercial and Medicaid payment rates to Medicare payment rates and examined patient cost sharing., Results: Pharmacy-submitted claims for adult vaccine doses were almost always paid (commercial 98.5%; Medicaid 100%). As the physician office accounted for the clear majority (79% commercial; 69% Medicaid) of medical (non-pharmacy) vaccination services, we limited further analyses of both commercial and Medicaid medical claims to the physician office setting. In the physician office setting, rates of payment were high with commercial rates of payment (97.9%) greater than Medicaid rates (91.6%). Reasons for non-payment varied, but generally related to the complexity of adult vaccine recommendations (patient diagnosis does not match recommendations) or insurance coverage (complex contracts, multiple insurance payers). Vaccine administration services were also generally paid. Commercial health plan payments were greater for both vaccine dose and vaccine administration than Medicare payments; Medicaid paid a higher amount for the vaccine dose, but less for vaccine administration than Medicare. Patients generally had very low (commercial) or no (Medicaid) cost-sharing for vaccination., Conclusions: Adult vaccine dose claims were usually paid. Medicaid generally had higher rates of non-payment than commercial insurance., (Copyright © 2019 Elsevier Ltd. All rights reserved.)

Background: Human-capital based lifetime productivity estimates are frequently used in cost-of-illness (COI) analyses and, less commonly, in cost-effectiveness analyses (CEAs). Previous US estimates assumed that labor productivity and real earnings both grow by 1% per year. Objectives: This study presents estimates of annual and lifetime productivity for 2016 using data from the American Community Survey, the American Time Use Survey, and the Current Population Survey, and with varying assumptions about real earnings growth. Methods: The sum of market productivity (gross annual personal labor earnings adjusted for employer-paid benefits) and the imputed value of non-market time spent in household, caring, and volunteer services was estimated. The present value of lifetime productivity at various ages was calculated for synthetic cohorts using annual productivity estimates, life tables, discount rates, and assumptions about future earnings growth rates. Results: Mean annual productivity was $57,324 for US adults in 2016, including $36,935 in market and $20,389 in non-market productivity. Lifetime productivity at birth, using a 3% discount rate, is roughly $1.5 million if earnings grow by 1% per year and $1.2 million if future earnings growth averages 0.5% per year. Conclusions: Inclusion of avoidable productivity losses in societal-perspective CEAs of health interventions is recommended in new US cost-effectiveness guidelines. However, estimates vary depending on whether analysts choose to estimate total productivity or just market productivity, and on assumptions made about growth in future productivity and earnings.

Objective: The aim of this analysis was to examine treatment patterns in patients with acute myeloid leukemia (AML) in routine clinical practice in the United States, including factors influencing the choice of front-line treatment intensity and the effect of age and treatment line., Methods: We used data from the Adelphi AML Disease Specific Programme, a real-world, cross-sectional survey conducted in 2015. Physicians completed patient record forms providing patients' demographic and clinical characteristics., Results: In total, 61 academic, non-academic, and office-based hematologists and hematology/oncology specialists provided data on 457 patients with AML; 284 had ≥20% blasts (World Health Organization defined AML) and were included in the analysis. In the front-line setting, 60% of patients received high-intensity therapy, most commonly cytarabine plus anthracycline; the most common low-intensity treatments were hypomethylating agents. Primary drivers for selecting high-intensity versus low-intensity treatment were age, performance status and comorbidities; 67%, 64% and 61% of physicians stated they would prescribe high-intensity treatment to patients aged <65 years, with good performance status or no comorbidities, respectively. In practice, patients aged <60 years were more likely to receive high-intensity induction treatment (high vs. low intensity by age p < .0001). In a selected cohort of relapsed/refractory patients, 69% of patients received high-intensity therapy (78% of patients aged <60 years and 57% of patients aged ≥60 years)., Conclusions: Most patients in this analysis of real-world survey data received well established, front-line induction therapies. Treatment intensity was determined by age, comorbidities and performance status, as recommended by guidelines.

We identified 16 Advisory Committee on Immunization Practices (ACIP) presentations from 2012 to 2016 that indicated 'cost' or 'economic' content. Characteristics were reviewed, abstracted, and tabulated to quantify and assess the transparency and consistency of economic evidence presented to ACIP. To assess transparency, we documented if each study identified author affiliation, conflicts of interest, study limitations, a clearly described model structure and other model attributes. To assess consistency, we identified the frequency of specific modeling choices, including the perspective, types of health outcomes considered, inclusion of specific types of costs, discount rate, and use of sensitivity analyses. Our results indicate that the content in these presentations appear to be transparent overall and consistent in several important areas, such as study perspective and health outcomes. However, we find the inclusion of particular types of direct costs, indirect costs, program costs, and sensitivity analyses are areas that could improve consistency., (Published by Elsevier Ltd.)

After 20years with no reported measles cases, on May 15, 2014 the Centers for Disease Control and Prevention (CDC) was notified of two cases testing positive for measles-specific immunoglobulin M (IgM) antibodies in the Federated States of Micronesia (FSM). Under the Compact of Free Association, FSM receives immunization funding and technical support from the United States (US) domestic vaccination program managed by the Centers for Disease Control and Prevention (CDC). In a collaborative effort, public health officials and volunteers from FSM and the US government worked to respond and contain the measles outbreak through an emergency mass vaccination campaign, contact tracing, and other outbreak investigation activities. Contributions were also made by United Nations Children's Emergency Fund (UNICEF) and World Health Organization (WHO). Total costs incurred as a result of the outbreak were nearly $4,000,000; approximately $10,000 per case. Direct medical costs (≈$141,000) were incurred in the treatment of those individuals infected, as well as lost productivity of the infected and informal caregivers (≈$250,000) and costs to contain the outbreak (≈$3.5 million). We assessed the economic burden of the 2014 measles outbreak to FSM, as well as the economic responsibilities of the US. Although the US paid the majority of total costs of the outbreak (≈67%), examining each country's costs relative to their respective economy illustrates a far greater burden to FSM. We demonstrate that while FSM was heavily assisted by the US in responding to the 2014 Measles Outbreak, the outbreak significantly impacted their economy. FSM's economic burden from the outbreak is approximately equivalent to their entire 2016 Fiscal Year budget dedicated to education., (Published by Elsevier Ltd.)

Study Design: A cross-sectional observational study of physicians and patients with chronic low-back pain (CLBP) in the United States., Objective: To evaluate the association of patient-reported CLBP severity with other patient-reported outcomes., Summary of Background Data: Appropriate management of patients with CLBP can be enhanced by understanding how patients perceive the severity of their CLBP., Methods: Data were from the 2009 Adelphi Disease Specific Programme. Patients reported the severity of their CLBP condition by answering the question Please rate how your chronic lower back pain condition is today with responses of mild, moderate, and severe. Patient-reported severity was evaluated with respect to scores on standard patient self-report measures of pain, pain interference, health status, functional disability, work productivity, and questions addressing satisfaction with medications for treating CLBP., Results: Of 1860 subjects in the CLBP database, 1363 (73.3%) agreed to complete the survey. This sample was similarly distributed between males (49%) and females (51%), with mean age 54.8 years: 52% were employed at least part-time. CLBP severity was rated as mild, moderate and severe by 28.6%, 53.3%, and 18.2% of patients, respectively. With increasing CLBP severity, significant differences were observed in increased pain (P<0.0001), pain interference with function (P<0.0001), and impairment while working due to CLBP (P<0.01), mainly due to presenteeism. Increased work impairment resulted in higher costs related to lost work productivity; annual lost productivity costs were estimated at $7080, $16,616, and $25,032 per patient for mild, moderate, and severe CLBP, respectively (P<0.0001 for pairwise comparisons). Patient satisfaction with pain-related medication was inversely associated with CLBP severity., Conclusions: The association between patient-reported CLBP severity and other patient-reported outcomes demonstrates that in the clinical setting, patient-reported CLBP severity provides an accurate and suitable indicator of patient-reported health status. This indicator may be useful for guiding management strategies for CLBP patients.

Objective: Recent national surveys have documented that the majority of adults in the United States do not meet the recommended levels of healthy lifestyle-related behaviors. The Nutrition and Physical Activity (NuPA) study was designed to promote fruit and vegetable consumption, physical activity, and weight management for a working population., Method: Data were collected nationwide, USA, from 2005 to 2007 and analyzed in 2008. A total of 2470 employed participants were randomized into the self-help (SH: n=1191) or self-help plus telephone counseling (SH+C: n=1279) group. The SH+C group received nine structured telephone counseling sessions in addition to the print materials., Results: A series of hierarchical regression analyses for each of the health behavior outcomes in the present-at-follow-up subsample (n=1098-1148) revealed that the SH+C was effective in increasing fruit and vegetable consumption. Among the overweight and obese participants, weight loss was significant in both the SH and SH+C groups., Conclusion: Using a theory-based behavioral change counseling technique and targeting multiple health behaviors among employed individuals, our findings demonstrate that the addition of telephone counseling to mailed self-help materials is effective in promoting healthy diet and weight management., (2009 Elsevier Inc.

Aims: To evaluate whether the Asthma Control Test (ACT) score is predictive of Global Initiative for Asthma (GINA) guideline-defined classification levels of asthma control. The ACT is a validated, 5-item, patient-completed measure of asthma control with a recall period of four weeks., Methods: Cross-sectional survey comparing ACT score and GINA classification of asthma control among 2949 patients attending primary care physicians and specialists in France, Germany, Italy, Spain, the UK, and the USA., Results: The area under the receiver operating characteristics curve for ACT score predicting GINA control was 0.84 (95% CI 0.82-0.85). An ACT score of <19 (not well-controlled asthma) correctly predicted GINA-defined partly controlled/uncontrolled asthma 94% of the time, while an ACT score of >20 predicted GINA-defined controlled asthma 51% of the time, with kappa statistic of 0.42, representing moderate agreement., Conclusions: An ACT score <19 is useful for identifying patients with poorly controlled asthma as defined by GINA.

Objective: Since sustained treatment-adherence is often problematic and may limit clinical outcomes among bipolar disorder (BPD) patients, we sought risk factors to guide clinical prediction of nonadherence., Methods: Data were from a 2005 US national sample providing questionnaire responses by 131 randomly selected prescribing psychiatrists and their adult BPD patients. We contrasted demographic and clinical factors in treatment-adherent versus nonadherent patients (strictly defined as missing > or =1 dose within 10 days) in univariate analyses followed by multivariate logistic-regression modeling., Results: Of 429 DSM-IV BPD patients (79% type-I; 62% women; 17% minorities), 34% reported missing > or = 1 dose of psychotropic medication within 10 days, 20% missed entire daily doses at least once, and only 2.5% missed all doses for 10 days. However, their prescribing psychiatrists considered only 6% as treatment-nonadherent. Factors significantly associated with nonadherence in multivariate modeling ranked: alcohol-dependence > youth > greater affective morbidity > various side effects > or = comorbid obsessive-compulsive disorder > or = recovering from mania-hypomania. Unrelated were sex, diagnostic subtype, and other comorbidities. Since most patients received > or = 2 psychotropics, potential relationships between treatment-complexity and adherence were obscured., Conclusions: Prevalent treatment-nonadherence among American BPD patients, and striking underestimation of the problem by prescribing clinicians may encourage increasingly complex treatment-regimens of untested value, but added expense, risk of adverse effects, and uncertain impact on treatment-adherence itself., ((c) 2007 John Wiley & Sons, Ltd.)
