Burden of hereditary transthyretin amyloidosis on quality of life.

INTRODUCTION: Hereditary transthyretin (hATTR) amyloidosis is a progressive, degenerative disease, with peripheral neuropathy, cardiomyopathy, and other clinical manifestations. In this study we examine the impact of hATTR amyloidosis on quality of life (QOL). METHODS: Neuropathy-specific QOL, measured with the Norfolk QOL-Diabetic Neuropathy questionnaire, was compared between patients with hATTR amyloidosis and patients with type 2 diabetes, whereas generic QOL, measured with the 36-item Short Form Health Survey version 2 (SF-36v2), was compared between patients with hATTR amyloidosis, the general population, and patients with chronic diseases. RESULTS: Neuropathy-specific QOL for patients with hATTR amyloidosis was nearly equivalent to that of patients with type 2 diabetes with diabetic neuropathy accompanied by a history of ulceration, gangrene, or amputation. Generic QOL was worse than that seen in the general population, with physical functioning worse than that for patients with multiple sclerosis and congestive heart failure. DISCUSSION: Patients with hATTR amyloidosis show significant burden on QOL, particularly in physical functioning. Muscle Nerve 60: 169-175, 2019.

A Real-World Effectiveness Study Using a Mobile Application to Evaluate Early Outcomes with Upadacitinib in Rheumatoid Arthritis.

INTRODUCTION: The impact of upadacitinib on rheumatoid arthritis (RA) symptoms was evaluated during the first 12 weeks of treatment via patient-reported outcomes (PROs) using a mobile health application (app). METHODS: Participating rheumatologists from the CorEvitas RA Registry (prospective, observational cohort) recruited patients with RA initiating upadacitinib treatment. A modified version of the ArthritisPower® app was used to collect PROs, including the Routine Assessment of Patient Index Data 3 (RAPID3), duration of morning joint stiffness, and the Patient-Reported Outcomes Measurement Information System (PROMIS)-Fatigue 7a Short Form at baseline and weeks 1-4, 8, and 12. RAPID3 responses over time were assessed using Kaplan-Meier estimation to determine the proportion of patients achieving disease activity improvement and minimal clinically important difference (MCID). Results were analyzed for all patients initiating upadacitinib and a subsample of TNF inhibitor (TNFi)-experienced patients with moderate to severe disease at baseline. RESULTS: A total of 103 patients with RA initiating upadacitinib (62.1% TNFi-experienced) were included. At week 12, 53 patients (51.4%) completed the study and provided PRO data via the app. Among all patients, improvements in RAPID3, pain, morning stiffness, and fatigue were observed at week 1 and were maintained or further improved through week 12. At week 12, 37.5% of patients achieved RAPID3 low disease activity. Starting at week 1, improvements in RAPID3 disease activity category (19.4% of patients) and achievement of MCID (16.3%) were reported, with nearly 50% of patients achieving these outcomes by week 4 (RAPID3 category: 48.8%; MCID: 49.2%) and 60% by week 12 (RAPID3 category: 59.6%; MCID: 59.8%). TNFi-experienced patients generally reported similar outcomes. Patient-reported medication convenience and compliance were generally high. CONCLUSIONS: In this real-world cohort of patients with RA, treatment with upadacitinib was associated with early and significant improvement in RAPID3, pain, morning stiffness, and fatigue regardless of prior TNFi experience. Clinically meaningful improvement in RAPID3 patient-reported disease activity was observed as early as week 1, with continued improvement reported through week 12.

Ultrasonography guidance reduces complications and costs associated with thoracentesis procedures.

PURPOSE.: We performed an analysis of hospitalizations involving thoracentesis procedures to determine whether the use of ultrasonographic (US) guidance is associated with differences in complications or hospital costs as compared with not using US guidance. METHODS.: We used the Premier hospital database to identify patients with ICD-9 coded thoracentesis in 2008. Use of US guidance was identified using CPT-4 codes. We performed univariate and multivariable analyses of cost data and adjusted for patient demographics, hospital characteristics, patient morbidity severity, and mortality. Logistic regression models were developed for pneumothorax and hemorrhage adverse events, controlling for patient demographics, morbidity severity, mortality, and hospital size. RESULTS.: Of 19,339 thoracentesis procedures, 46% were performed with US guidance. Mean total hospitalization costs were $11,786 (±$10,535) and $12,408 (±$13,157) for patients with and without US guidance, respectively (p < 0.001). Unadjusted risk of pneumothorax or hemorrhage was lower with US guidance (p = 0.019 and 0.078, respectively). Logistic regression analyses demonstrate that US is associated with a 16.3% reduction likelihood of pneumothorax (adjusted odds ratio 0.837, 95% CI: 0.73-0.96; p= 0.014), and 38.7% reduction in likelihood of hemorrhage (adjusted odds ratio 0.613, 95% CI: 0.36-1.04; p = 0.071). CONCLUSIONS.: US-guided thoracentesis is associated with lower total hospital stay costs and lower incidence of pneumothorax and hemorrhage. © 2011 Wiley Periodicals, Inc. J Clin Ultrasound, 2011.

Whole genome sequencing and characteristics of extended-spectrum beta-lactamase producing Escherichia coli isolated from poultry farms in Banaskantha, India.

Worldwide dissemination of extended-spectrum -lactamase (ESBL)-producing Escherichia coli constitutes an emerging global health issue, with animal food products contributing as potential reservoirs. ESBL E. coli infection is associated with the high mortality and mobility rate in developing countries due to less susceptibility to antibiotics. The present study aimed to elucidate the molecular characteristics and sequence-based analysis of ESBL E. coli in the Gujarat state of India. This study included 108 E. coli strains were isolated from different poultry farms (broiler and layer) in the Banaskantha District. PCR was employed to identify genotypic ESBL-producing antimicrobial resistance genes. Overall, a high occurrence of ESBL genes was found in poultry farms due to the high usage of antimicrobials. The PCR analysis revealed that 79.62% of isolates were detected positive with one or more ESBL genes. Among them, bla TEM (63.88%) was found to be the predominant genotype, followed by bla SHV (30.55%) and bla OXA (28.70%). In the bla CTX-M group, a higher occurrence was observed in bla CTX-M-9 (23.14%), followed by bla CTX-M-2 (24.07%) and bla CTX-M-1 (22.22%). We used the whole-genome sequencing (WGS) method to evaluate the antimicrobial resistance genes, virulence factors, single nucleotide polymorphisms (SNPs), plasmid replicons, and plasmid-mediated AMR genes of one ESBL E. coli isolated. We examined the genetic relatedness of a human pathogenic E. coli strain by comparing its sequence with the broad geographical reference E. coli sequences. Escherichia coli ST 681 was determined using multi-locus sequence typing. We compared our findings to the reference sequence of Escherichia coli str. K- 12 substr. MG1655. We found 24,937 SNPs with 21,792 in the genic region, 3,145 in the intergenic region, and six InDels across the genome. The WGS analysis revealed 46 antimicrobial resistance genes and seven plasmid-mediated AMR genes viz., tetA, qnrS1, dfrA14, sul2, aph(3")-lb, aph(6)-ld, and Aph(3')-la. The ST 681 was found to have Cib, traT, and terC virulence factors and two plasmid replicons, IncFII(pHN7A8) and IncI1-I(Alpha). This study revealed a higher occurrence of ESBL E. coli detected in poultry.

Healthcare Resource Use in Patients with Immune-Mediated Conditions Treated with Targeted Immunomodulators During COVID-19 Pandemic: A Retrospective Claims Analysis.

INTRODUCTION: The impact of the COVID-19 pandemic on routine medical care may result in altered healthcare resource use in patients with immune-mediated conditions. The aim of this study was to determine the impact of treatment interruptions in patients with and without COVID-19 infections who were treated with targeted immunomodulators (TIMs) in the USA. METHODS: Data from the IBM® MarketScan® Research Databases were analyzed in patients with immune-mediated conditions from January 1, 2018, through December 31, 2020. Healthcare resource use (HCRU) including hospitalizations, emergency department (ED) visits, in-person outpatient visits, and respiratory outcomes was assessed in a cohort of patients without COVID-19 who had uninterrupted versus interrupted TIM use. The impact of treatment interruption on HCRU and respiratory outcomes was also evaluated in a cohort of patients with COVID-19. Results from adjusted logistic regression were reported as adjusted odds ratios (aORs) with 95% confidence intervals. RESULTS: Approximately 25% of patients in both the COVID-19 (N = 787) and non-COVID-19 cohorts (N = 77,178) experienced interruptions in TIM therapy. In the non-COVID-19 cohort, the likelihood of being hospitalized was 20% less in patients with uninterrupted versus interrupted TIM use (aOR = 0.80, 95% CI 0.71-0.90). Patients with uninterrupted TIM use had a similar likelihood of an ED visit (aOR = 0.99, 95% CI 0.91-1.08) and respiratory outcome (aOR = 0.97, 95% CI 0.71-1.31) versus patients with interrupted TIM use. The likelihood of having an in-person outpatient visit was 87% greater in patients with uninterrupted versus interrupted TIM use (aOR = 1.87, 95% CI 1.81-1.94). Similar findings were observed in the COVID-19 cohort. CONCLUSION: This analysis of real-world claims data showed that uninterrupted TIM use was not associated with an increased likelihood of hospitalizations, ED visits, or negative respiratory outcomes compared to interrupted TIM use among patients with immune-mediated conditions, regardless of COVID-19 diagnosis.

Pediatric cannabinoid hyperemesis: two cases.

Cannabinoid hyperemesis has recently been described in the literature. It is a syndrome characterized by severe nausea and hyperemesis in the setting of chronic marijuana abuse and, to date, has been described only in adults. We describe the syndrome in 2 pediatric patients, for whom extensive gastrointestinal workups failed to identify a clear cause and cessation of marijuana use resulted in the alleviation of their symptoms. As in most published adult cases, compulsive bathing was present in both of these cases.

Assessing disease severity in bio-naïve patients with RA on treatment with csDMARDs: insights from the Corrona Registry.

INTRODUCTION: This study aimed to characterize disease burden among patients with rheumatoid arthritis (RA) with moderate-to-high disease activity who had received conventional synthetic disease-modifying anti-rheumatic drug (csDMARD) monotherapy for ≥ 6 months but had not advanced to a biologic therapy. METHODS: Patients enrolled in the US Corrona RA Registry between June 1, 2014, and January 30, 2018, with 6 months of continuous csDMARD monotherapy, with moderate-to-high disease activity, who remained biologic naive, and who had ≥ 1 follow-up visit were identified. Disease activity was assessed among patients with a 6-month follow-up visit (± 3 months). Descriptive statistics were used to compare demographics and disease characteristics between patients with or without treatment advancement. RESULTS: The study included 409 patients with a disease activity assessment at 6 months (mean (SD) age 65.9 (12.6) years; mean duration of csDMARD therapy 407 (221) days). Of those patients, more than half (54%, n = 219) remained in moderate-to-high disease activity. Patients remaining in moderate-to-high vs. remission-to-low disease activity had higher baseline swollen (6.1) and tender joint counts (6.8). Over the 6-month period, treatment advancement occurred in 29% of patients. Those who advanced treatment (n = 118) vs. did not advance treatment (n = 291) were younger, had a shorter duration of RA, had higher disease activity, and reported higher levels of pain and fatigue. CONCLUSIONS: The substantial number of patients with persistent moderate-to-high disease on csDMARDs over a 6-month period and who did not advance treatment indicates that there is considerable need for a treat-to-target approach to care for patients with RA.Key Points•For patients with RA and an inadequate response to treatment with initial csDMARD monotherapy, guidelines recommend treatment advancement; however, this may not be occurring in real-world clinical settings.•In the current study, a substantial proportion of patients (54%) on csDMARDs had persistent moderate-to-severe disease activity at the 6-month (± 3 months) follow-up visit; however, only 29% of patients had their medication treatment advanced, indicating that there is considerable need for a treat-to-target approach to care for patients with RA.•Patients with younger age, shorter RA duration, and higher disease activity were more likely to have their medication treatment advanced, which suggests that potentially more aggressive treatment of disease activity is needed across the whole RA population.

The effect of serum urate on gout flares and their associated costs: an administrative claims analysis.

BACKGROUND: Increased serum urate (sUA) levels (> or =6.0 mg/dL) are associated with increased likelihood of acute gout attacks, or "flares." OBJECTIVES: Identify gout flares with administrative claims data; examine the relationship between sUA and flares; examine the association between sUA and flare-related costs. METHODS: This retrospective administrative claims analysis examined subjects with gout (> or =2 medical claims with ICD-9-CM diagnosis code 274.xx or > or =1 claim with a gout diagnosis and > or =1 pharmacy claim for allopurinol, probenecid, colchicine, or sulfinpyrazone) between January 1, 2002 and March 31, 2004. Each subject was observed during 1-year baseline and 1-year follow-up periods. Gout flares were identified with an algorithm using claims for services associated with flares. Outcomes were sUA (mg/dL) and flare-related health care costs. Logistic regression examined the likelihood of flare; generalized linear modeling regression measured the impact of baseline sUA on flare costs, controlling for demographic and health status variables. RESULTS: The study sample comprised 18,243 subjects with mean age of 53.9 years. sUA was available for 4277 (23%) subjects. Sixty-two percent (11,253) of subjects had > or =1 flare. The number of mean, unadjusted flares increased with sUA. Logistic results showed subjects with baseline sUA > or =6.0 relative to sUA <6.0 had 1.3 times the odds of gout flare (P <0.05). Generalized linear modeling results showed that baseline sUA > or =6.0 was associated with 2.1 to 2.2 times higher flare costs than was baseline sUA <6.0 (P <0.05). CONCLUSIONS: sUA was a significant predictor both of gout flare and related costs. This highlights the importance of gout management strategies aimed at controlling sUA.

Disease-related and all-cause health care costs of elderly patients with gout.

BACKGROUND: Gout is a common cause of inflammatory arthritis in the United States, and its prevalence has increased in recent decades, especially among older adults. Older adults with gout are of particular interest because they tend to experience higher rates of tophi, an advanced stage of gout, than do younger patients. OBJECTIVE: For older adults with gout to (1) assess health care utilization and costs from a third-party payer perspective; (2) evaluate health care costs related to tophi; and (3) explore the relationship between elevated serum uric acid (UA) level, an indicator of disease control, and health care utilization. METHODS: Data were extracted from the Integrated Healthcare Information Services (IHCIS) claims database (1999-2005), which includes approximately 40 private health plans in the United States for approximately 13 million beneficiaries, about 4% of whom are aged 65 years or older. Patients were included in the study if they: (1) had 2 diagnoses of gout (International Classification of Diseases, Ninth Revision, Clinical Modification [ICD-9-CM] code of 274.xx) on separate medical claims or 1 gout diagnosis plus at least 1 gout-related pharmacy claim (i.e., allopurinol, probenecid, colchicines, or sulfinpyrazone); (2) were at least 65 years old at the first diagnosis date (study index date); and (3) had 1 year of continuous eligibility both before and after the study index date. A comparison sample of elderly members without gout was selected using a 1:1 match to gout patients based on age, gender, and geographic region. Individuals in the comparison group also had 1 year of continuous eligibility both before and after the study index date, defined as the same index date as the respective matched gout patient. Patients with possible tophi were identified from at least 1 medical claim with an ICD-9-CM code 274.8x (274.81=gouty tophi of the ear; 274.82 = gouty tophi of other sites except ear; 274.89 = gout with other specified manifestations) during the 12-month study period following the study index date. Additionally, a subgroup of gout patients with at least 1 serum UA measure was selected. Patients were divided into 3 groups according to their serum UA level on the earliest test date (serum UA index date): low (< 6 mg per dL), moderate-high (6-8.99 mg per dL), and very high (> or = 9 mg per dL). Health care utilization was categorized into inpatient services, outpatient services, emergency room services, other medical services, and use of prescription drugs. Medical services were classified by the place of service indicated in the claim. Medical services costs and pharmacy costs were defined as the amount paid to the provider plus member cost share (e.g., deductible, copayment). Two types of costs were assessed in the analysis: total all-cause health care costs and gout-related costs, defined as costs associated with a claim with a primary or secondary diagnosis of gout (ICD-9-CM code 274.xx). Differences in total all-cause health care costs were calculated by comparing (1) gout patients and gout-free members during the 12-month period following the study index date; (2) gout patients with and without tophi during the 12-month period following the study index date; and (3) gout patients across the 3 serum UA categories during the 12-month period following the serum UA index date. Multivariate regression analyses were used to control for patients' baseline demographics, prior comorbidities indicated by the Deyo-Charlson Comorbidity Index, and number of medications used during the 12 months prior to the study index date. RESULTS: Over the 7 years of claims data through 2005, there were 11,935 gout patients aged 65 years or older. The sample had an average age of 71.4 years and was predominantly male (73.5%). In the 12 months following the study index date, the mean unadjusted per-patient gout-related health care cost was $876 (standard deviation $3,373) in 2005 dollars, 5.9% of the total all-cause health care cost of $14,734 (SD $27,401) for gout patients. Unadjusted total 12-month all-cause health care cost for the gout-free members was $9,219 (SD $20,186). After statistical adjustment for comorbidities, the difference in total 12-month all-cause health care costs between gout patients and gout-free members was $3,038 (P < 0.001). A diagnosis suggesting possible tophi was found in 2.0% (n = 240) of gout patients in the sample. After statistical adjustment for comorbidities, the difference in total 12-month all-cause health care costs between gout patients with and without tophi was $5,501 (P < 0.001), and the difference in total adjusted 12-month gout-related costs between patients with and without tophi was $1,710 (P < 0.001). Among the 2,237 (18.7%) patients with at least 1 serum UA measure, 28.3% had a low serum UA level, 52.4% had a moderate-high serum UA level, and 19.3% had a very high serum UA level. For patients with low, moderate-high, and very high serum UA levels, regression-adjusted gout-related costs in the 12 months following the serum UA index date represented, respectively, 2.9%, 2.7%, and 3.9% of total regression-adjusted health care costs. The group with a very high serum UA level had significantly higher regression-adjusted total 12-month all-cause health care costs and gout-related costs compared with those with a low serum UA level ($3,103 and $276 higher, respectively). CONCLUSIONS: Elderly patients with a diagnosis of gout have higher all-cause health care utilization and costs compared with matched elderly patients without a diagnosis of gout. Gout-related costs represent about 6% of total health care costs in elderly patients with gout. Very high serum UA levels (i.e., > or = 9 mg per dL) and diagnoses suggesting possible tophi are associated with increased utilization and costs in elderly gout patients.

Major depressive disorder with subthreshold hypomanic (mixed) features: A real-world assessment of treatment patterns and economic burden.

BACKGROUND: To compare outcomes for individuals with major depressive disorder (MDD) with or without subthreshold hypomania (mixed features) in naturalistic settings. METHODS: Using the Optum Research Database (1/1/2009─10/31/2014), a retrospective analysis of individuals newly diagnosed with MDD was conducted. Continuous enrollment for 12-months before and after the initial MDD diagnosis was required. MDD with subthreshold hypomania (mixed features) (MDD-MF) was defined based on ≥1 hypomania diagnosis within 30 days after an MDD diagnosis during the one-year follow-up period, in the absence of bipolar I diagnoses. Psychiatric medication use, healthcare utilization, and costs during the one-year follow-up period were compared using multivariate logistic and gamma regressions, controlling for baseline differences. RESULTS: Of 130,626 MDD individuals, 652 (0.5%) met the operational definition of MDD-MF. Compared to the MDD-only group, the MDD-MF group had more suicidality (2.0% vs. 0.5%), anxiety disorders (46.8% vs. 34.0%), and substance use disorders (15.5% vs. 6.1%, all P<0.001). More individuals with MDD-MF were treated with antidepressants (83.6% vs. 71.6%), mood stabilizers (50.5% vs. 2.7%), atypical antipsychotics (39.0% vs. 5.5%), and polypharmacy with multiple drug classes (72.1% vs. 22.7%, all P<0.001). Individuals with MDD-MF had higher hospitalizations rates (24.2% vs. 10.5%) and total healthcare costs (mean: $15,660 vs. $10,744, all P<0.001). LIMITATIONS: The commercial claims data used were not collected for research purposes and may over- or under-represent certain populations. No specific claims-based diagnostic code for MDD with mixed features exists. CONCLUSIONS: Greater use of mood stabilizers, atypical antipsychotics, polypharmacy, and healthcare resources provides evidence of the complexity and severity of MDD-MF. Identifying optimal treatment regimens for this population represents a major unmet medical need.

Gout medication treatment patterns and adherence to standards of care from a managed care perspective.

OBJECTIVE: To determine allopurinol treatment patterns and adherence to published standards of care for patients with gout. PATIENTS AND METHODS: This retrospective claims analysis in a managed care database included patients 18 years or older, with continuous eligibility for 1 year before and after the start date and 2 or more visits during which the gout disease code (274.xx) was assigned or 1 or more pharmacy prescriptions for a gout-specific medication between January 1, 2000, and December 31, 2002 (intake period). Factors associated with compliance with allopurinol therapy were measured based on the medication possession ratio, and adherence to 2 quality-of-care indicators for gout management was assessed using multivariable logistic regression analysis. RESULTS: A total of 64.9% of allopurinol users had a modal daily dose or the most commonly observed daily dose of 300 mg/d, median length of therapy was 3 months, and a high proportion of patients had a medication possession ratio of 10% or less. Suggested quality-of-care Indicators for gout had low performance: 53% of patients with renal impairment received a modal daily dose of 300 mg or greater, and 83% of patients who started taking allopurinol did not have their serum urate levels measured within 180 days. Patients with gout flares were less likely to be compliant with allopurinol (odds ratio, 0.50; 95% confidence interval, 0.40-0.63). Patients with renal impairment at baseline were 3.2 times more likely to undergo serum urate testing than patients without renal impairment (odds ratio, 3.20; 95% confidence Interval, 1.25-8.23). CONCLUSION: There was low compliance with allopurinol therapy for treatment of gout. Patients potentially received suboptimal quality of care as measured by serum urate testing and appropriateness of allopurinol dosing in patients with renal impairment.

The economic burden of gout on an employed population.

OBJECTIVE: To examine the economic burden of illness of gout in an employed population, quantifying the impact on employers annual health benefit costs for medical and prescription claims, sick leave, short- and long-term disability, and workers' compensation. METHODS: Adjudicated claims data from 300000 employees from 2001 through 2004 were utilized. T-tests were used to compare demographic data and medical costs and services by Agency for Healthcare Research and Quality (AHRQ) diagnostic categories. Two-part models were used to determine average annual health benefit costs overall and medical costs by place of delivery. A risk stratification quintile analysis was also performed utilizing gout-specific medical and pharmaceutical costs. RESULTS: There were 1171 employees with gout identified (total n = 249 038). All demographic variables between the two groups were statistically different (p

Effects of ß-mercaptoethanol on in vitro maturation and glutathione level of buffalo oocytes.

AIM: The present study was carried out to evaluate the effect of supplementation of ß-mercaptoethanol (ß-ME) on in vitro maturation rate and glutathione (GSH) level of buffalo oocytes. MATERIALS AND METHODS: Oocytes were recovered from buffalo's ovaries collected from government approved slaughter house (near Kamela darwaza, Surat) of Surat Municipal Corporation. The obtained oocytes were in vitro matured in maturation media supplemented with 0 µM (117 oocytes), 100 µM (46 oocytes) and 200 µM (42 oocytes) concentration of ß-ME. After 24 h of incubation, maturation rate of oocytes and intra-cellular GSH level were determined. RESULTS: The results showed that the presence of ß-ME did not influence (p>0.05) the oocyte maturation rate. However, GSH level increased significantly (p<0.05) in matured oocytes when supplemented with 100 µM and 200 µM ß-ME (6.19±0.10 and 6.37±0.20 pmol/oocyte) as compared to control media (4.68±0.26 pmol/oocyte). CONCLUSION: It was concluded that ß-ME may have a potential to increase the meiotic maturation of in vitro cultured oocytes and protect it from oxidative damage.

Evaluation of physiological and biochemical responses in different seasons in Surti buffaloes.

AIM: This study was conducted to evaluate the impact of hot dry, hot humid and comfortable season on physiological, hematological, biochemical, and oxidative stress parameters in Surti buffaloes. MATERIALS AND METHODS: Ten lactating Surti buffaloes of similar physiological status were selected. Based on the temperature-humidity index (THI), their natural exposure to the environment was categorized as hot dry (THI1), hot humid (THI2) and moderate winter/comfort season (THI3). Blood/serum samples were collected and analyzed for physiological, hematological, biochemical, and oxidative stress parameters. The results were analyzed using standard statistical methods. RESULTS: With increase in THI, significant rise in physiological parameters such as respiration rate (RR), hematological parameters such as red blood cell (RBC), hematocrit, hemoglobin (Hb) and mean cell Hb concentration (MCHC), biochemical parameters such as alanine aminotransferase (ALT), Na, K, creatinine, blood urea nitrogen, Mn, Cu and Zn, hormones such as cortisol and oxidative stress parameters such as glutathione peroxidase (GPx), superoxide dismutase (SOD), lipid peroxide (LPO) and total antioxidant status (TAS) and significant decline in glucose, cholesterol and triiodothyronine (T3) was observed. CONCLUSION: It was concluded that THI is a sensitive indicator of heat stress and is impacted by ambient temperature more than the relative humidity in buffaloes. Higher THI is associated with significantly increased RR, total RBC count, Hb, hematocrit, MCHC, ALT, urea, sodium, creatinine, triiodothyronine, SOD, GPx, LPO and TAS and with significant decrease in glucose, cholesterol and triiodothyronine (T3).

Traumatic Brain Injury: Patient Characteristics, Hospital Costs and Trends Over Time.

Background: Traumatic brain injury (TBI) is an increasingly diagnosed condition, but the trends in TBI visits and the cost of which have not been quantified from the hospital perspective. Objectives: To quantify the costs of TBI stratified by inpatient and outpatient visits and to examine trends in TBI incidence over time. Methods: This descriptive study utilized data for 2007-2012 from the Premier hospital database, which includes clinical and utilization information from hospitals across the United States. TBI was identified through International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) codes. Descriptive data were obtained to identify the TBI costs, visit costs, patient characteristics, and intertemporal trends in TBI rates. Results: TBI patients were treated on an outpatient basis 88% of the time. Nearly 45% (44.3%) of TBI patients requiring inpatient admissions were age 65 or over, and 20% of TBI patients treated as an outpatient were age 75 or over. Children aged 4 or younger accounted for nearly 14% of TBI cases treated on an outpatient basis. TBI patients treated in the inpatient setting incurred fairly long hospital visits (mean 4.8 days; median 3.0 days) and substantial hospital costs (mean $12,717; median $8,176). The rate of TBI visits have risen substantially over time, especially among children under age 18 years and patients in the Northeast US Census Region. Conclusion: TBI is a serious medical condition that appears to be on the rise. Large differences exist between the hospital costs associated with TBIs treated in the inpatient and outpatient settings. Further research to understand factors affecting the costs and clinical outcomes of TBI can help refine treatment strategies to enhance patient outcomes while providing cost effective care.

A Passive Monitoring System in Assisted Living Facilities: 12-Month Comparative Study.

The GE QuietCare® passive monitoring system uses advanced motion sensor technology that learns the daily living patterns of senior community residents and sends alerts when certain out-of-the-ordinary events occur. This study compared falls, hospitalizations, care level changes, and resident attrition between two similar assisted living facilities where one facility adopted the QuietCare® monitoring system and the other did not over a 12-month period. Average falls per week were significantly lower in the QuietCare® facility than the control facility. There was also a trend toward fewer weekly hospitalizations in the QuietCare® facility. There was higher resident retention at the QuietCare® facility. This study provides evidence of direct benefits to both the resident and the facility for the use of QuietCare®. There was a significant reduction in the number of falls, as well as a general facility performance improvement measured by care level consistency and higher resident retention rates.

Evaluation of hospital complications and costs associated with using ultrasound guidance during abdominal paracentesis procedures.

OBJECTIVE: Abdominal paracentesis is commonly performed for diagnostic, therapeutic, and palliative indications, but the use of ultrasound guidance for these procedures is relatively recent, variable, and not well documented. A retrospective database analysis of abdominal paracentesis procedures was performed to determine whether ultrasound guidance was associated with differences in adverse events (AEs) or hospital costs, compared to procedures without ultrasound guidance. METHODS: The hospital database maintained by Premier was used to identify patients with abdominal paracentesis International Classification of Diseases - 9th Revision - Clinical Modification (ICD-9 code 54.9, Common Procedural Terminology CPT-4 codes 49080, 49081) in 2008. Use of ultrasound guidance was determined via patient billing data. The incidence of selected AEs and patients' hospitalization costs were calculated for two groups: procedures with ultrasound guidance and those without. Univariate and multivariable analyses were performed to evaluate differences between groups. RESULTS: This study identified 1297 abdominal paracentesis procedures, 723 (56%) with ultrasound and 574 (44%) without. The indications for paracentesis were similar between the two groups. The incidence of AEs was lower in ultrasound-guided procedures: all AEs (1.4% vs 4.7%, p = 0.01), post-paracentesis infection (0.41% vs 2.44%, p = 0.01), hematoma (0.0% vs 0.87%, p = 0.01), and seroma (0.14% vs 1.05%, p = 0.03). Analyses adjusted for patient and hospital covariates revealed significant reductions in AEs (OR = 0.349, 95% CI = 0.165, 0.739, p = 0.0059) and hospitalization costs ($8761 ± $5956 vs $9848 ± $6581, p < 0.001) for procedures with ultrasound guidance vs those without. LIMITATIONS: There are several limitations to using claims data for clinical analyses; causality cannot be determined, the possibility of miscoded or missing data, and the inability to control for elements not captured in claims data that may influence clinical outcomes. CONCLUSIONS: The use of ultrasound guidance in abdominal paracentesis procedures is associated with fewer AEs and lower hospitalization costs than procedures where ultrasound is not used.

Adenosine-stress cardiac magnetic resonance imaging in suspected coronary artery disease: a net cost analysis and reimbursement implications.

The health and economic implications of new imaging technologies are increasingly relevant policy issues. Cardiac magnetic resonance imaging (CMR) is currently not or not sufficiently reimbursed in a number of countries including Germany, presumably because of a limited evidence base. It is unknown, however, whether it can be effectively used to facilitate medical decision-making and reduce costs by serving as a gatekeeper to invasive coronary angiography. We investigated whether the application of CMR in patients suspected of having coronary artery disease (CAD) reduces costs by averting referrals to cardiac catheterization. We used propensity score methods to match 218 patients from a CMR registry to a previously studied cohort in which CMR was demonstrated to reliably identify patients who were low-risk for major cardiac events. Covariates over which patients were matched included comorbidity profiles, demographics, CAD-related symptoms, and CAD risk as measured by Morise scores. We determined the proportion of patients for whom cardiac catheterization was deferred based upon CMR findings. We then calculated the economic effects of practice pattern changes using data on cardiac catheterization and CMR costs. CMR reduced the utilization of cardiac catheterization by 62.4%. Based on estimated catheterization costs of € 619, the utilization of CMR as a gatekeeper reduced per-patient costs by a mean of € 90. Savings were realized until CMR costs exceeded € 386. Cost savings were greatest for patients at low-risk for CAD, as measured by baseline Morise scores, but were present for all Morise subgroups with the exception of patients at the highest risk of CAD. CMR significantly reduces the utilization of cardiac catheterization in patients suspected of having CAD. Per-patient savings range from € 323 in patients at lowest risk of CAD to € 58 in patients at high-risk but not in the highest risk stratum. Because a negative CMR evaluation has high negative predictive value, its application as a gatekeeper to cardiac catheterization should be further explored as a treatment option.

Impact of noncompliance with urate-lowering drug on serum urate and gout-related healthcare costs: administrative claims analysis.

OBJECTIVE: To determine the association between allopurinol compliance and serum urate (sUA) level; and examine the association between sUA and gout-related healthcare costs in a large managed care population. RESEARCH DESIGN AND METHODS: This retrospective administrative claims analysis examined subjects with gout (> or = 2 medical claims with ICD-9-CM diagnosis code 274.xx or > or = 1 claim with a gout diagnosis and > or = 1 pharmacy claim for allopurinol, probenecid, colchicine, or sulfinpyrazone) between January 1, 2002 and March 31, 2004. Each subject was observed during 1-year pre-index and 1-year post-index periods. MAIN OUTCOME MEASURES: Outcomes were allopurinol medication possession ratio (MPR) and compliance (MPR > or = 0.80), sUA (mg/dL), and gout-related healthcare costs. 'Post-allopurinol' sUA was measured during three periods after the first observed allopurinol fill: 30-89 days; 90-149 days; > or = 150 days. A baseline sUA on or before the start of the post-index period was also identified. Outcomes were stratified by post-allopurinol or baseline sUA and compliance. Generalized linear modeling (GLM) regression measured the impact of baseline sUA on gout-related healthcare costs, controlling for demographic and health status variables. RESULTS: The study sample comprised 18,243 subjects with mean age of 53.9 years. In all, 55% (n = 10,073) of subjects used allopurinol. There were 1473 (8.1%) subjects with a post-allopurinol sUA and 2438 (13.4%) subjects with a baseline sUA result. Among all subjects with a post-allopurinol sUA, 45.6% were compliant; between 49.3% and 56.8% of compliant subjects had an sUA < 6.0 mg/dL compared with 22.5-27.8% of non-compliant subjects, depending on the post-allopurinol time period (all p < 0.001). GLM results showed gout-related costs associated with baseline sUA > or = 6.0 and < 9.0 mg/dL were 58% higher (95% confidence interval (CI): 1.012 -2.456; p = 0.044) than were costs for sUA < 6.0 mg/dL. There was no significant difference in gout-related costs between baseline sUA < 6.0 mg/dL and > or = 9.0 mg/dL. CONCLUSIONS: Analysis revealed an important associations between allopurinol compliance, sUA, and gout-related costs: compliance was positively associated with favorable sUA (<6.0 mg/dL) in unadjusted comparisons. GLM showed that baseline sUA < 6.0 was inversely associated with gout-related costs relative to baseline sUA > or = 6.0 and <9.0 mg/dL. Nevertheless, a substantial portion of subjects, even compliant ones, did not achieve sUA < 6.0 mg/dL. These results should be interpreted carefully in light of study limitations, including incomplete laboratory data, the potentially incorrect inference that medications were taken as prescribed, and lack of generalizability from Medicare managed care enrollees to the broader Medicare population.

Frequency, risk, and cost of gout-related episodes among the elderly: does serum uric acid level matter?

OBJECTIVE: We examined the association between serum uric acid (SUA) level and the frequency, risk, and cost of gout flares among the elderly. METHODS: Data were extracted from the Integrated Healthcare Information Services claims database (1999-2005). Patients were included if they had gout, were aged 65 years and older and had both medical and pharmacy benefits, and electronic laboratory data. Patients with gout and gouty episodes were identified using algorithms based on ICD-9-CM codes and medications. Logistic regression and negative binomial regressions were used to study the relationship between SUA concentration and the annual frequency and one-year risk of gout episodes. Generalized linear models were used to examine the direct healthcare costs associated with gout episodes in the 30 days following each episode. RESULTS: Elderly patients with gout (n = 2237) with high (6-8.99 mg/dl) and very high (> 9 mg/dl) SUA concentrations were more likely to develop a flare within 12 months compared to patients with normal (< 6 mg/dl) SUA levels (OR 2.1, 95% CI 1.7-2.6; OR 3.4, 95% CI 2.6-4.4, respectively). In multivariate regressions, the average annual number of flares increased by 11.9% (p < 0.001) with each unit-increase in SUA level above 6 mg/dl (p < 0.001). Among patients with very high SUA levels, average adjusted total healthcare and gout-related costs per episode were $2,555 and $356 higher, respectively, than those of patients with normal SUA levels (both p < 0.001). CONCLUSION: Higher SUA levels are associated with increased frequency and risk of gout episode, and with higher total and gout-related direct healthcare costs per episode.
