HIV economic burden of illness in the Veterans Health Administration population.

The objective was to assess the human immunodeficiency virus (HIV) economic burden of illness in the Veterans Health Administration (VHA) population. Adults (aged 18-64 years) with a HIV diagnosis (International Classification of Diseases 9th Revision, Clinical Modification [ICD-9-CM] code 042.x, V08) from 1 June 2007 to 31 May 2012 were selected from VHA Medical SAS(®) data-sets. Continuous VHA insurance coverage 12-month pre- and postindex date, with no antiretroviral therapy (ART) prescriptions within 180 days pre-index date, was required for treatment-naive (TN) HIV-infected patients. One baseline CD4 count or HIV viral load measured within three months after HIV diagnosis or one ART anchor drug claim postindex date was required for group comparison. All-cause health-care costs and utilizations were evaluated and stratified by CD4 cell count, viral load, nonnucleoside reverse transcriptase inhibitor (NNRTI) anchor drugs (efavirenz/non-efavirenz), and ART (NNRTI/PI/INSTI/CCR-5 Antagonist-based) regimen cohorts. The overall economic burden was compared between HIV-infected vs. non-HIV-infected patients. CD4 count, viral load, and treatment patterns and the associated costs were compared among TN patients. A 1:1 propensity score matching (PSM) was used to adjust for baseline differences. A total of 25,648 HIV-infected patients were identified (mean age 51; 96.4% male; 49.7% non-Hispanic black) of which 11,371 were TN. HIV-infected patients incurred higher PSM-adjusted total costs than non-HIV-infected patients ($25,232 vs. $10,206, p < 0.0001). Total costs for TN with CD4 cell counts ≤50 cells/mm(3) were higher than all other CD4 cell strata (p < 0.001). Total costs for TN with viral loads >100,000 copies/mL were higher than all other viral load categories (p < 0.001). Efavirenz-treated patients incurred higher ART-related ($8663 vs. $2846, p = 0.0266), but lower non-ART-related ($2339 vs. $6628, p = 0.0042) pharmacy costs than non-efavirenz patients. NNRTI-based cohort incurred lower total costs than protease inhibitor-based ($32,829 vs. $39,073, p = 0.0005) but no significant differences compared to integrase strand transfer inhibitor cohorts. This study offers new health-care costs and resource utilization estimates associated with the burden of HIV in the VHA population.

Review of the impact of NNRTI-based HIV treatment regimens on patient-reported disease burden.

While the burden of HIV disease is well documented, the value of non-nucleoside reverse transcriptase inhibitor (NNRTI)-based therapy regimens in reducing patient burden is not well understood. The purpose of this study was to examine patient-reported health among those receiving NNRTI-based regimens to understand their incremental value in reducing the burden of HIV. We conducted a structured literature review using PubMed to identify NNRTI trials utilizing validated patient-reported outcome (PRO) instruments during 2005-2011. The search strategy included a PubMed search to identify relevant studies based on disease, instrument, PRO, and NNRTI medication terms; and a manual search of bibliographies of identified papers. Data abstracted from each study included study type, treatment regimen(s), and PRO results. Of 11 trials identified, 8 (73%) reported significance of changes in a PRO over time and 10 (91%) reported significance of PRO changes between groups. Several domains were assessed, with significant findings (between or within groups) observed in: physical health/well-being (n = 5), emotional status/well-being (n = 2), symptoms (n = 2), anxiety (n = 2), gastrointestinal upset (n = 2), psychological health (n = 1), functional and global well-being (n = 1), fatigue/energy (n = 1), depression (n = 1), change in body appearance (n = 1), pain (n = 1), headache (n = 1), bad dreams/nightmares (n = 1), problems having sex (n = 1), and general health perception (n = 1). In conclusion, NNRTIs have been observed most frequently to improve patient-reported physical health and well-being. Treatments are needed that can also reduce patient burden in areas of emotional well-being, cognitive functioning, and overall symptom profile.

Influence of real-world characteristics on outcomes for patients with methicillin-resistant Staphylococcal skin and soft tissue infections: a multi-country medical chart review in Europe.

BACKGROUND: Patient-related (demographic/disease) and treatment-related (drug/clinician/hospital) characteristics were evaluated as potential predictors of healthcare resource use and opportunities for early switch (ES) from intravenous (IV)-to-oral methicillin-resistant Staphylococcus aureus (MRSA)-active antibiotic therapy and early hospital discharge (ED). METHODS: This retrospective observational medical chart study analyzed patients (across 12 European countries) with microbiologically confirmed MRSA complicated skin and soft tissue infections (cSSTI), ≥3 days of IV anti-MRSA antibiotics during hospitalization (July 1, 2010-June 30, 2011), and discharged alive by July 31, 2011. Logistic/linear regression models evaluated characteristics potentially associated with actual resource use (length of IV therapy, length of hospital stay [LOS], IV-to-oral antibiotic switch), and ES and ED (using literature-based and expert-verified criteria) outcomes. RESULTS: 1542 patients (mean ± SD age 60.8 ± 16.5 years; 61.5% males) were assessed with 81.0% hospitalized for MRSA cSSTI as the primary reason. Several patient demographic, infection, complication, treatment, and hospital characteristics were predictive of length of IV therapy, LOS, IV-to-oral antibiotic switch, or ES and ED opportunities. Outcomes and ES and ED opportunities varied across countries. Length of IV therapy and LOS (r = 0.66, p < 0.0001) and eligibilities for ES and ED (r = 0.44, p < 0.0001) showed relatively strong correlations. IV-to-oral antibiotic switch patients had significantly shorter length of IV therapy (-5.19 days, p < 0.001) and non-significantly shorter LOS (-1.86 days, p > 0.05). Certain patient and treatment characteristics were associated with increased odds of ES (healthcare-associated/ hospital-acquired infection) and ED (patient living arrangements, healthcare-associated/ hospital-acquired infection, initiating MRSA-active treatment 1-2 days post cSSTI index date, existing ED protocol), while other factors decreased the odds of ES (no documented MRSA culture, ≥4 days from admission to cSSTI index date, IV-to-oral switch, IV line infection) and ED (dementia, no documented MRSA culture, initiating MRSA-active treatment ≥3 days post cSSTI index date, existing ES protocol). CONCLUSIONS: Practice patterns and opportunity for further ES and ED were affected by several infection, treatment, hospital, and geographical characteristics, which should be considered in identifying ES and ED opportunities and designing interventions for MRSA cSSTI to reduce IV days and LOS while maintaining the quality of care.

Responsiveness of the MOS-HIV and EQ-5D in HIV-infected adults receiving antiretroviral therapies.

BACKGROUND: Selection of an appropriate patient-reported outcome (PRO) instrument for a clinical trial requires knowledge of the instrument's responsiveness to detecting treatment effects. The purpose of this study was to examine the responsiveness of two health-related quality of life (HRQL) instruments used in clinical trials involving HIV-infected adults: the HIV-targeted Medical Outcomes Study HIV Health Survey (MOS-HIV), and a generic measure, the EuroQol-5D (EQ-5D). METHODS: A systematic review identified clinical trials using the MOS-HIV or EQ-5D to assess outcomes for HIV-infected adults. Data abstracted from each study included study type, treatment regimen(s), PRO results, and effect size (either reported or calculated). Effect size was calculated as the difference between baseline and follow-up mean scores divided by the baseline standard deviation. Magnitude was categorized as small (d=0.20), medium (d=0.50), and large (d=0.80). RESULTS: Between 2005 and 2010, the MOS-HIV was administered in 12 trials. Significant differences were observed between groups and over time in physical health summary (PHS) and mental health summary (MHS) scores (P<0.05) in subjects switching therapy after experiencing Grade-2 adverse events. Effect sizes were medium (0.55 and 0.49 for PHS and MHS, respectively) among treatment-naïve adults beginning therapy (two studies), but negligible among treatment-experienced adults (0.04 and 0.13 for PHS and MHS, respectively; three studies). The EQ-5D was used in five trials between 2001 and 2010. It was responsive to occurrences of adverse events and opportunistic infections, with small-to-medium effect sizes (range 0.30-0.50) in each of its five dimensions. CONCLUSIONS: A systematic review of PRO study results showed both the MOS-HIV and EQ-5D were responsive to changes between groups and/or over time in treatment-naïve HIV-infected patients. These instruments may be used either individually or together in clinical trials to measure changes in HRQL.

Patient reported outcome instruments used in clinical trials of HIV-infected adults on NNRTI-based therapy: a 10-year review.

BACKGROUND: Patient-reported outcomes (PROs) may provide valuable information to clinicians and patients when choosing initial antiretroviral therapy. OBJECTIVE: To identify and classify PRO instruments used to measure treatment effects in clinical trials evaluating NNRTIs. METHODS: We conducted a structured literature review using PubMed to identify NNRTI trials published from March 2003 to February 2013. Studies identified--based on disease, instrument, PRO, and NNRTI medication terms were reviewed--to identify PRO instruments. Domains measured within each instrument were recorded to understand key areas of interest in NNRTIs. RESULTS: Of 189 articles reviewed, 27 validated instruments were administered in 26 unique trials, with a mean of 1.9 instruments (median: 1; range: 1-7) per trial. The Medical Outcomes Study HIV Health Survey (MOS-HIV) was the most commonly used instrument (n = 8 trials). Seventeen trials (65%) included at least one multidimensional health-related quality of life (HRQL) instrument (HIV-targeted, n = 11; general, n = 8). Other validated instruments measured sleep (n = 5), depression (n = 5), anxiety (n = 4), psychiatric symptoms (n = 2), beliefs about HIV medications (n = 2), HIV symptoms (n = 1), and stress (n = 1). CONCLUSIONS: Although review of recent NNRTI trials suggests a lack of consensus on the optimal PRO instruments, a typical battery is comprised of a multidimensional HRQL measure coupled with one or more symptom measures. Further work is needed to clarify advantages and disadvantages of using specific PRO instruments to measure relevant constructs and to identify the most useful batteries of instruments for NNRTI trials.

Economic and Humanistic Burden Associated with Depression and Anxiety Among Adults with Non-Communicable Chronic Diseases (NCCDs) in the United States.

INTRODUCTION: Patients with both major depressive disorder (MDD) and generalized anxiety disorder (GAD) in addition to one or multiple comorbid non-communicable chronic diseases (NCCDs) face unique challenges. However, few studies have characterized how the burden of co-occurring MDD and GAD differs from that of only MDD or only GAD among patients with NCCDs. METHODS: In this study, we used Medical Expenditures Panel Survey data from 2010-2017 to understand how the economic and humanistic burden of co-occurring MDD and GAD differs from that of MDD or GAD alone among patients with NCCDs. We used generalized linear models to investigate this relationship and controlled for patient sociodemographics and clinical characteristics. RESULTS: Co-occurring MDD and GAD was associated with increases in mean annual per patient inpatient visits, office visits, emergency department visits, annual drug costs, and total medical costs. Among patients with 3+ NCCDs, MDD or GAD only was associated with lower odds ratios (ORs) of limitations in activities of daily living (ADLs; 0.532 and 0.508, respectively) and social (0.503, 0.526) and physical limitations (0.613, 0.613) compared to co-occurring MDD and GAD. Compared to patients with co-occurring MDD and GAD, having MDD only or GAD only was associated with significantly lower odds of cognitive limitations (0.659 and 0.461, respectively) in patients with 1-2 NCCDs and patients with 3+ NCCDs (0.511, 0.416). DISCUSSION: Comorbid MDD and GAD was associated with higher economic burden, lower quality of life, and greater limitations in daily living compared to MDD or GAD alone. Health-related economic and humanistic burden increased with number of NCCDs.

Evaluating the Cost-Effectiveness of Celecoxib versus Ibuprofen and Naproxen in Patients with Osteoarthritis in United Arab Emirates Based on the PRECISION Trial.

OBJECTIVE: Data on osteoarthritis patients from the PRECISION trial were used to evaluate the cost-effectiveness of celecoxib (100 mg twice daily) versus ibuprofen (600-800 mg three times daily) and naproxen (375-500 mg twice daily). The perspective was that of the United Arab Emirates (UAE) healthcare system. METHODS: Discrete-state Markov model with monthly cycles, 30-month horizon, and 3% discount rate was constructed to assess incremental costs per quality adjusted life year (QALYs) gained from reduced incidence of three safety domains examined in PRECISION: renal, serious gastrointestinal (GI), and major adverse cardiovascular events (MACE). Costs for managing these toxicities were derived from Dubai Administrative Billing Claims (2018). Median monthly drug costs were derived from UAE Ministry of Health and Prevention's published prices ($26.98 celecoxib; $20.25 ibuprofen; $20.50 naproxen). Health utility and excess mortality associated with toxicities were sourced from the literature. The willingness-to-pay thresholds used were 1 and 3 GDP per capita ($40,000-$120,000). RESULTS: The total average cost per patient was $812.88 for celecoxib, $775.26 for ibuprofen, and $731.17 for naproxen while cost components attributed to toxicities were lowest with celecoxib ($360.26, $438.31, and $388.60, respectively). Patients on celecoxib had more QALYs (1.339), compared with ibuprofen (1.335) and naproxen (1.337), resulting in an incremental cost-effectiveness ratio of $11,502/QALY gained for celecoxib versus ibuprofen and $39,779 for celecoxib versus naproxen. Probabilistic sensitivity analyses demonstrated celecoxib to be 81% cost-effective versus ibuprofen and 50% versus naproxen at $40,000/QALY. The most influential model parameters were MACE relative safety and drug costs. CONCLUSION: From UAE third payer perspective, celecoxib is a long-term cost-effective treatment for osteoarthritis patients when compared with ibuprofen, and equally likely as naproxen to be cost-effective. With the expected increasing burden of chronic diseases in the Gulf region, study findings can inform decisions regarding the cost-effective pain management of osteoarthritis in UAE.

Economic and humanistic burden associated with noncommunicable diseases among adults with depression and anxiety in the United States.

Aims: This study estimated the economic and humanistic burden associated with chronic non-communicable diseases (NCCDs) among adults with comorbid major depressive and/or any anxiety disorders (MDD and/or AAD).Materials and methods: A retrospective analysis was conducted using the Medical Expenditure Panel Survey data (2010-2015). The analytic cohort included adults (≥18 years) with MDD only (C1), AAD only (C2), or both (C3). The presence of either of 6 NCCDs (cardiovascular diseases [CVD], pulmonary disorders [PD], pain, high cholesterol, diabetes, and obesity) were assessed. Study outcomes included healthcare costs, activity limitations, and quality of life. Multivariate regressions were conducted in each of the 3 cohorts to evaluate the association between the presence of NCCDs and outcomes.Results: The analytic sample included 9,160,465 patients: C1 (4,391,738), C2 (3,648,436), C3 (1,120,292). Pain (59%) was the most common condition, followed by CVD (55%), high cholesterol (50%), obesity (42%), PD (17%), and diabetes (14%). Mean annual healthcare costs were the greatest for C3 ($14,317), followed by C1 ($10,490) and C2 ($7,906). For C1, CVD was associated with the highest increment in annual costs ($3,966) followed by pain ($3,617). For C2, diabetes was associated with the highest incremental annual costs ($4,281) followed by PD ($2,997). For C3, cost trends were similar to those seen in C2. NCCDs resulted in a significant decrease in physical quality of life across all cohorts. Pain was associated with a significantly higher likelihood of self-reported physical, social, cognitive, and activity limitations compared to those without pain.Conclusions: 60% of patients with MDD and/or AAD had at least one additional NCCD, which significantly increased the economic and humanistic burden. These findings are important for payers and clinicians in making treatment decisions. These results underscore the need for development of multi-pronged interventions which aim to improve quality of life and reduce activity limitations among patients with mental health disorders and NCCDs.

Early switch/early discharge opportunities for hospitalized patients with methicillin resistant Staphylococcus aureus complicated skin and soft tissue infections: Saudi Arabia and United Arab Emirates.

OBJECTIVES: To describe opportunities for early switch (ES) from intravenous (IV) to oral (PO) antibiotics and early discharge (ED) of patients hospitalized in the Kingdom of Saudi Arabia (KSA) and the United Arab Emirates (UAE) with methicillin-resistant Staphylococcus aureus (MRSA) complicated skin and soft tissue infections (cSSTIs). METHODS: This retrospective medical chart review study enrolled physicians from 16 KSA and UAE sites to collect data for 107 MRSA cSSTI patients. RESULTS: Actual length of MRSA-active treatment was 13.3±9.3 mean days in KSA and 11.2±3.9 mean days in UAE, with a mean of 11.8±9.3 days of MRSA-targeted IV therapy in KSA and 10.7±4.3 days in UAE. 12.5% in KSA met ES criteria and potentially could have discontinued IV therapy 4.0±2.9 days sooner; 44.0% in UAE could have discontinued 6.6±3.6 days sooner. Patients were hospitalized for a mean 28.6±45.0 days in KSA and 13.1±5.9 days in UAE. 25.0% in KSA and 48.0% in UAE met ED criteria and potentially could have been discharged 6.1±8.0 days earlier in KSA and 7.9±5.0 days earlier in UAE. CONCLUSIONS: A significant proportion of patients hospitalized for MRSA cSSTI could be eligible for ES or ED opportunities, resulting in potential for reductions in IV and bed days.

Early switch/early discharge opportunities for hospitalized patients with methicillin-resistant Staphylococcus aureus complicated skin and soft tissue infections in Brazil.

BACKGROUND: Early antibiotic switch and early discharge protocols have not been widely studied in Latin America. Our objective was to describe real-world treatment patterns, resource use, and estimate opportunities for early switch from intravenous to oral antibiotics and early discharge for patients hospitalized with methicillin-resistant Staphylococcus aureus complicated skin and soft-tissue infections. MATERIALS/METHODS: This retrospective medical chart review recruited 72 physicians from Brazil to collect data from patients hospitalized with documented methicillin-resistant Staphylococcus aureus complicated skin and soft tissue infections between May 2013 and May 2015, and discharged alive by June 2015. Data collected included clinical characteristics and outcomes, hospital length of stay, methicillin-resistant Staphylococcus aureus-targeted intravenous and oral antibiotic use, and early switch and early discharge eligibility using literature-based and expert-validated criteria. RESULTS: A total of 199 patient charts were reviewed, of which 196 (98.5%) were prescribed methicillin-resistant Staphylococcus aureus -active therapy. Only four patients were switched from intravenous to oral antibiotics while hospitalized. The mean length of methicillin-resistant Staphylococcus aureus-active treatment was 14.7 (standard deviation, 10.1) days, with 14.6 (standard deviation, 10.1) total days of intravenous therapy. The mean length of hospital stay was 22.2 (standard deviation, 23.0) days. The most frequent initial methicillin-resistant Staphylococcus aureus-active therapies were intravenous vancomycin (58.2%), intravenous clindamycin (19.9%), and intravenous daptomycin (6.6%). Thirty-one patients (15.6%) were discharged with methicillin-resistant Staphylococcus aureus -active antibiotics of which 80.6% received oral antibiotics. Sixty-two patients (31.2%) met early switch criteria and potentially could have discontinued intravenous therapy 6.8 (standard deviation, 7.8) days sooner, and 65 patients (32.7%) met early discharge criteria and potentially could have been discharged 5.3 (standard deviation, 7.0) days sooner. CONCLUSIONS: Only 2% of patients were switched from intravenous to oral antibiotics in our study while almost one-third were early switch eligible. Additionally, one-third of hospitalized patients with methicillin-resistant Staphylococcus aureus complicated skin and soft tissue infections were early discharge eligible indicating opportunity for reducing intravenous therapy and days of hospital stay. These results provide insight into possible benefits of implementation of early switch/early discharge protocols in Brazil.

Pharmacoeconomic and associated cost savings among women who were prescribed systemic conjugated estrogens therapy compared with those without menopausal therapy.

OBJECTIVE: To explore changes in healthcare costs among postmenopausal women in a commercial population who were prescribed conjugated estrogens for menopausal symptoms. METHODS: Using the MarketScan dataset from April 1, 2008 through September 30, 2012, postmenopausal women aged ≥45 years, who were prescribed conjugated estrogen tablets (Premarin), were identified. A comparative cohort of postmenopausal women with vasomotor symptoms without any menopause therapy was also identified. Women included were required to have continuous medical and pharmacy benefits for 6 months before and 12 months after index date, with baseline characteristics compared using chi-square and t tests. The 6 and 12-month change (difference in follow-up and baseline costs) in direct healthcare costs was calculated and a difference-in-differences model was used to compare the incremental change at 6 and 12 months in healthcare costs between the cohorts, adjusting for demographic and clinical characteristics. RESULTS: The study included 1,404 women who were prescribed conjugated estrogens, and 3,096 untreated women. Women prescribed conjugated estrogens were significantly younger (52 vs 54 years; P < 0.0001) and had a lower Charlson comorbidity index score (0.29 vs 0.41; P < 0.001) compared with the untreated women. After adjusting for baseline characteristics, women treated with conjugated estrogens showed a greater difference in the change in total healthcare costs (-$1,601 vs -$503; P = 0.044), including inpatient stay costs (-$1,431 vs -$28; P < 0.0001), between the baseline and follow-up periods compared with untreated women. CONCLUSIONS: Women who were prescribed oral conjugated estrogens had a significantly greater reduction in healthcare costs after treatment initiation compared with untreated postmenopausal women.

Burden of methicillin-resistant Staphylococcus aureus pneumonia among hospitalized patients in Lebanon and Saudi Arabia.

OBJECTIVES: The objective of this study is to describe the real-world treatment patterns and burden of suspected or confirmed methicillin-resistant Staphylococcus aureus (MRSA) pneumonia in Saudi Arabia and Lebanon. METHODS: A retrospective chart review study evaluated 2011-2012 data from hospitals in Saudi Arabia and Lebanon. Patients were included if they had been discharged with a diagnosis of MRSA pneumonia, which was culture proven or suspected based on clinical criteria. Hospital data were abstracted for a random sample of patients to capture demographics (eg, age and comorbidities), treatment patterns (eg, timing and use of antimicrobials), hospital resource utilization (eg, length of stay), and clinical outcomes (eg, clinical status at discharge and mortality). Descriptive results were reported using frequencies or proportions for categorical variables and mean and standard deviation for continuous variables. RESULTS: Chart-level data were collected for 93 patients with MRSA pneumonia, 50 in Saudi Arabia and 43 in Lebanon. The average age of the patients was 56 years, and 60% were male. The most common comorbidities were diabetes (39%), congestive heart failure (30%), coronary artery disease (29%), and chronic obstructive pulmonary disease (28%). Patients most frequently had positive cultures from pulmonary (87%) and blood (27%) samples. All isolates were sensitive to vancomycin, teicoplanin, and linezolid, and only one-third of the isolates tested were sensitive to ciprofloxacin. Beta-lactams (inactive therapy for MRSA) were prescribed 21% of the time across all lines of therapy, with 42% of patients receiving first-line beta-lactams. Fifteen percent of patients did not receive any antibiotics that were considered to be MRSA active. The mean hospital length of stay was 32 days, and in-hospital mortality was 30%. CONCLUSION: The treatment for MRSA pneumonia in Saudi Arabia and Lebanon may be suboptimal with inactive therapy prescribed a substantial proportion of the time. The information gathered from this Middle East sample provides important perspectives on the current treatment patterns.

Treatment patterns, resource utilization, and outcomes among hospitalized patients with methicillin-resistant Staphylococcus aureus complicated skin and soft tissue infections in Lebanon and Saudi Arabia.

OBJECTIVES: To describe treatment patterns and medical resource use for methicillin-resistant Staphylococcus aureus (MRSA) complicated skin and soft tissue infections (cSSTI) in Saudi Arabia and Lebanon in terms of drug selection against the infecting pathogen as well as hospital resource utilization and clinical outcomes among patients with these infections. METHODS: This retrospective chart review study evaluated 2011-2012 data from five hospitals in Saudi Arabia and Lebanon. Patients were included if they had been discharged with a diagnosis of MRSA cSSTI, which was culture-proven or suspected based on clinical criteria. Hospital data were abstracted for a random sample of patients with each infection type to capture demographics, treatment patterns, hospital resource utilization, and clinical outcomes. Statistical analysis was descriptive. RESULTS: Data were abstracted from medical records of 87 patients with MRSA cSSTI; mean age 52.4±25.9 years and 61% male. Only 64% of patients received an MRSA active initial therapy, with 56% of first-line regimens containing older beta-lactams. The mean total length of stay was 26.3 days, with the majority (19.1 days) spent in general wards. Surgical procedures included incision and drainage (22% of patients), debridement (14%), and amputation (5%). Mechanical ventilation was required by 9% of patients, with a mean duration of 18 days per patient. Hemodialysis was required by four patients (5%), two of whom were reported to have moderate to severe renal disease on admission, for a mean of 5.5 days. Inpatient mortality was 8%. Thirty-nine percent were prescribed at least one antibiotic at discharge, with the most commonly prescribed discharge antibiotics being clindamycin (44%), ciprofloxacin (18%), trimethoprim/sulfamethoxazole (12%), and linezolid (9%). CONCLUSION: This Middle Eastern real-world study of resource use and treatment patterns in MRSA cSSTI indicates that management of this condition could be further optimized in terms of drug selection and resource utilization.

Outcomes and cost of coronary artery bypass graft surgery in the United States and Canada.

BACKGROUND: We sought to determine whether there is a difference in in-hospital outcomes and costs for coronary artery bypass graft surgery (CABG) between the United States and Canada. METHODS: We compared the outcomes and costs of treating 12 017 consecutive patients (4698 US and 7319 Canadian patients) undergoing CABG at 5 US and 4 Canadian hospitals. Participating hospitals used the same cost accounting system to provide patient-level clinical, resource utilization, and cost-of-treatment data (excluding physicians' fees). Canadian costs were converted to US dollars using purchasing power parities. RESULTS: Compared with Canadian patients, US patients were older (mean +/- SD age, 68.0 +/- 10.4 vs 63.7 +/- 9.8 years [P<.001]), more likely to be female (27.4% vs 21.8% [P<.001]), and discharged from the hospital sooner (mean +/- SD length of stay, 8.7 +/- 0.1 vs 9.5 +/- 0.1 days [P<.001]). In-hospital costs of treatment were substantially higher in the United States than in Canada (mean +/- SD cost, dollar 20,673 +/- dollar 241 vs dollar 10,373 +/- dollar 123 [P<.001]; median, dollar 16,036 vs dollar 7880). After controlling for demographic and clinical differences, length of stay in Canada was 16.8% longer than in the United States; there was no difference in in-hospital mortality; and the cost in the United States was 82.5% higher than in Canada (P<.001). CONCLUSIONS: The in-hospital cost of CABG in the United States is substantially higher than in Canada. This difference is due to higher direct and overhead costs in US hospitals, is not explained by demographic or clinical differences, and does not lead to superior clinical outcomes.

Economic evaluation among Chinese patients with nosocomial pneumonia caused by methicillin-resistant Staphylococcus aureus and treated with linezolid or vancomycin: a secondary, post-hoc analysis based on a Phase 4 clinical trial study.

OBJECTIVE: To assess cost-effectiveness of linezolid vs vancomycin in treating nosocomial pneumonia caused by methicillin-resistant Staphylococcus aureus (MRSA-NP) in China and the impact of renal failure on healthcare resource utilization (HCRU) and costs. METHODS: Cost-effectiveness analysis was conducted based on data from the ZEPHyR trial, with efficacy measured by treatment success and costs calculated from HCRU. Confidence intervals (CI) for cost, efficacy and incremental cost-effectiveness ratios (ICER) were calculated by non-parametric bootstrap. Chi-square test was used for renal failure rate and t-test for HCRU/cost comparisons. Impact of renal failure was assessed using regression model. RESULTS: Data from 448 patients (1:1 linezolid:vancomycin) were analyzed. More patients treated with linezolid achieved success (55% [95% CI = 48-62%]) than with vancomycin (45% [38-52%]). Treatment cost were ¥79,551 (95% CI = ¥72,421-¥86,680) for linezolid vs ¥77,587 (¥70,656-¥84,519) for vancomycin in Beijing, ¥90,995 (¥82,598-¥99,393) vs ¥89,448 (¥81,295-¥97,601) in Guangzhou, ¥82,383 (¥74,956-¥89,810) vs ¥80,799 (¥73,545-¥88,054) in Nanjing and ¥59,413 (¥54,366-¥64,460) vs ¥57,804 (¥52,613-¥62,996) in Xi'an. Per successful treatment, the ICER of linezolid over vancomycin were ¥19,719 (-¥143,553 to ¥320,980) (Beijing), ¥15,532 (-¥185,411 to ¥349,693) (Guangzhou), ¥15,904 (-¥161,935 to ¥314,987) (Nanjing) and ¥16,145 (-¥100,738 to ¥234,412) (Xi'an). From simulations, the majority of linezolid cases had greater efficacy and higher costs and more than one third had greater efficacy and lower costs. More vancomycin patients developed renal failure (15% vs 4%, p < 0.001). Patients with renal failure had higher cost (Nanjng: ¥100,449 (SD = ¥65,080) vs ¥74,944 (SD = ¥49,632), p = 0.002). CONCLUSION: Linezolid was more cost-effective than vancomycin in treating MRSA-NP from a Chinese payer's perspective, and associated with less renal failure, HCRU and cost.

Coronary artery bypass graft surgery: do women cost more?

BACKGROUND: Coronary artery bypass graft surgery (CABG) in women has been associated with worse clinical outcomes than CABG in men. However, little is known about the impact of sex on the cost of CABG. OBJECTIVE: To examine the impact of sex on hospital course and the cost of CABG. METHODS: Hospital course and cost were examined among 2880 female and 9137 male patients from four Canadian and five American hospitals. Data were obtained from a resource and cost accounting system used by each of the nine hospitals. RESULTS: Among the 12,017 patients who underwent CABG, 24% (n=2880) were women and 76% (n=9137) were men. Women had a significantly longer length of stay (LOS) than did men (10.3+/-0.2 days and 8.9+/-0.08 days, respectively; P<0.0001) and a significantly higher in-hospital mortality than did men (2.6% and 1.5%, respectively; P<0.0001). The total unadjusted cost was higher for women than for men both in Canada (US$11,200+/-268 and US$10,143+/-139, respectively; P<0.0001) and the United States (US$22,715+/-509 and US$19,906+/-269, respectively; P<0.0001). After adjusting for age and comorbid conditions, female sex was associated with a 10% increase in LOS (P<0.0001), a 97% increase in mortality (P=0.0006) and a 7% increase in overall cost (P<0.0001). CONCLUSION: Compared with men, women undergoing CABG had a modestly increased LOS and a higher mortality. Total in-hospital cost was higher for women in each of the nine hospitals studied. Compared with other clinical variables, female sex is a relatively minor determinant of cost. Nevertheless, because of the expected increase in the number of women undergoing CABG in the future, this increased cost may translate into an important economic burden.

In-hospital cost of abdominal aortic aneurysm repair in Canada and the United States.

BACKGROUND: Global health care costs in Canada and the United States have been examined on a macroeconomic level. However, to our knowledge, comparative costs of specific procedures in the 2 countries have not been closely studied. METHODS: To perform a microeconomic comparison of costs of open abdominal aortic aneurysm (AAA) repair, we examined the costs of treating 1057 consecutive patients from 4 Canadian (n = 552) and 6 US (n = 505) hospitals. Participating hospitals used the same cost accounting system that provided demographic, clinical, and cost data (excluding physician's fees) for each patient. Canadian dollar costs were converted to US dollar costs using purchasing power parities. RESULTS: Compared with patients who underwent AAA repair in the United States, Canadian patients were significantly younger (mean +/- SD, 70.2 +/- 10.5 vs 73.3 +/- 8.5 years; P<.001) and were less likely to undergo elective repair (48.5% vs 73.3%; P<.001). The median length of hospital stay was longer in Canada (9.0 vs 7.0 days; P<.001), and mortality rates were similar (12.0% [Canada] vs 9.9% [United States]; P =.29). The mean +/- SEM cost of AAA repair was dollars 15 852 +/- dollars 790 in Canada compared with US dollars 23299 +/- US dollars 1410 in the United States. CONCLUSIONS: The cost of AAA repair is substantially higher in the United States compared with Canada, despite shorter lengths of stay and similar clinical outcomes. The difference in total treatment costs between Canadian and American hospitals was partially attributable to differences in direct costs, but was largely due to differences in overhead costs.

Early-switch/early-discharge opportunities for hospitalized patients with methicillin-resistant Staphylococcus aureus complicated skin and soft tissue infections: proof of concept in the United Arab Emirates.

OBJECTIVES: To describe real-world treatment patterns and health care resource use and to estimate opportunities for early-switch (ES) from intravenous (IV) to oral (PO) antibiotics and early-discharge (ED) for patients hospitalized in the United Arab Emirates (UAE) with methicillin-resistant Staphylococcus aureus (MRSA) complicated skin and soft tissue infections. METHODS: This retrospective observational medical chart review study enrolled physicians from four UAE sites to collect data for 24 patients with documented MRSA complicated skin and soft tissue infections, hospitalized between July 2010 and June 2011, and discharged alive by July 2011. Data include clinical characteristics and outcomes, hospital length of stay (LOS), MRSA-targeted IV and PO antibiotic use, and ES and ED eligibility using literature-based and expert-validated criteria. RESULTS: Five included patients (20.8%) were switched from IV to PO antibiotics while being inpatients. Actual length of MRSA-active treatment was 10.8±7.0 days, with 9.8±6.6 days of IV therapy. Patients were hospitalized for a mean 13.9±9.3 days. The most frequent initial MRSA-active therapies used were vancomycin (37.5%), linezolid (16.7%), and clindamycin (16.7%). Eight patients were discharged with MRSA-active antibiotics, with linezolid prescribed most frequently (n=3; 37.5%). Fifteen patients (62.5%) met ES criteria and potentially could have discontinued IV therapy 8.3±6.0 days sooner, and eight (33.3%) met ED criteria and potentially could have been discharged 10.9±5.8 days earlier. CONCLUSION: While approximately one-fifth of patients were switched from IV to PO antibiotics in the UAE, there were clear opportunities for further optimization of health care resource use. Over half of UAE patients hospitalized for MRSA complicated skin and soft tissue infections could be eligible for ES, with one-third eligible for ED opportunities, resulting in substantial potential for reductions in IV days and bed days.

Impact of age on hospital course and cost of coronary artery bypass grafting.

In-hospital outcomes and cost were examined among 2,272 elderly patients (> or =75 years) and 9,745 younger patients (<75 years) who underwent coronary artery bypass graft surgery at 5 United States and 4 Canadian hospitals. Hospital course and cost data were obtained from a resource and cost accounting system used by each of the 9 hospitals. Compared with younger patients, elderly patients had longer hospital stays, increased in-hospital mortality, and increased costs. After controlling for clinical differences, age > or =75 years was associated with an increase in cost of 11%. Given the aging North American population, these results have important implications for health care planning for the next several decades.
