A systematic review of the health-related quality of life and economic burdens of anorexia nervosa, bulimia nervosa, and binge eating disorder.

PURPOSE: To perform a systematic review of the health-related quality of life (HRQoL) and economic burdens of anorexia nervosa (AN), bulimia nervosa (BN), and binge eating disorder (BED). METHODS: A systematic literature search of English-language studies was performed in Medline, Embase, PsycINFO, PsycARTICLES, Academic Search Complete, CINAHL Plus, Business Source Premier, and Cochrane Library. Cost data were converted to 2014 Euro. RESULTS: Sixty-nine studies were included. Data on HRQoL were reported in 41 studies (18 for AN, 17 for BN, and 18 for BED), on healthcare utilization in 20 studies (14 for AN, 12 for BN, and 8 for BED), and on healthcare costs in 17 studies (9 for AN, 11 for BN, and only 2 for BED). Patients' HRQoL was significantly worse with AN, BN, and BED compared with healthy populations. AN, BN, and BED were associated with a high rate of hospitalization, outpatient care, and emergency department visits. However, patients rarely received specific treatment for their eating disorder. The annual healthcare costs for AN, BN, and BED were €2993 to €55,270, €888 to €18,823, and €1762 to €2902, respectively. CONCLUSIONS: AN, BN, and BED have a serious impact on patient's HRQoL and are also associated with increased healthcare utilization and healthcare costs. The burden of BED should be examined separately from that of BN. The limited evidence suggests that further research is warranted to better understand the differences in long-term HRQoL and economic burdens of AN, BN, and BED.

Healthcare costs and resource utilization of patients with binge-eating disorder and eating disorder not otherwise specified in the Department of Veterans Affairs.

OBJECTIVE: The objective of this study was to compare the one-year healthcare costs and utilization of patients with binge-eating disorder (BED) to patients with eating disorder not otherwise specified without BED (EDNOS-only) and to matched patients without an eating disorder (NED). METHODS: A natural language processing (NLP) algorithm identified adults with BED from clinical notes in the Department of Veterans Affairs (VA) electronic health record database from 2000 to 2011. Patients with EDNOS-only were identified using ICD-9 code (307.50) and those with NLP-identified BED were excluded. First diagnosis date defined the index date for both groups. Patients with NED were randomly matched 4:1, as available, to patients with BED on age, sex, BMI, depression diagnosis, and index month. Patients with cost data (2005-2011) were included. Total healthcare, inpatient, outpatient, and pharmacy costs were examined. Generalized linear models were used to compare total one-year healthcare costs while adjusting for baseline patient characteristics. RESULTS: There were 257 BED, 743 EDNOS-only, and 823 matched NED patients identified. The mean (SD) total unadjusted one-year costs, in 2011 US dollars, were $33,716 ($38,928) for BED, $37,052 ($40,719) for EDNOS-only, and $19,548 ($35,780) for NED patients. When adjusting for patient characteristics, BED patients had one-year total healthcare costs $5,589 higher than EDNOS-only (p = 0.06) and $18,152 higher than matched NED patients (p < 0.001). DISCUSSION: This study is the first to use NLP to identify BED patients and quantify their healthcare costs and utilization. Patients with BED had similar one-year total healthcare costs to EDNOS-only patients, but significantly higher costs than patients with NED.

Epidemiology, health-related quality of life and economic burden of binge eating disorder: a systematic literature review.

PURPOSE: To perform a systematic review on the epidemiology, the health-related quality of life (HRQoL) and economic burden of binge eating disorder (BED). METHODS: A systematic literature search of English-language articles was conducted using Medline, Embase, PsycINFO, PsycARTICLES, Academic Search Complete, CINAHL Plus, Business Source Premier and Cochrane Library. Literature search on epidemiology was limited to studies published between 2009 and 2013. Cost data were inflated and converted to 2012 US$ purchasing power parities. All of the included studies were assessed for quality. RESULTS: Forty-nine articles were included. Data on epidemiology were reported in 31, HRQoL burden in 16, and economic burden in 7 studies. Diagnosis of BED was made using 4th Edition of The Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) criteria in 46 studies. Lifetime prevalence of BED was 1.1-1.9% in the general population (DSM-IV). BED was associated with significant impairment in aspects of HRQoL relating to both physical and mental health; the Short Form 36 Physical and Mental Component Summary mean scores varied between 31.1 to 47.3 and 32.0 to 49.8, respectively. Compared to individuals without eating disorder, BED was related to increased healthcare utilization and costs. Annual direct healthcare costs per BED patient ranged between $2,372 and $3,731. CONCLUSIONS: BED is a serious eating disorder that impairs HRQoL and is related to increased healthcare utilization and healthcare costs. The limited literature warrants further research, especially to better understand the long-term HRQoL and economic burden of BED.

Clinical and cost outcomes of venous thromboembolism in Medicare patients undergoing total hip replacement or total knee replacement surgery.

BACKGROUND: Venous thromboembolism (VTE) occurs most often during hospitalization for major surgery or trauma but may also occur up to several months after surgery. Since the potential for VTE exists in a range of clinical settings, an assessment of its impact on overall outcomes and costs to the patient and to the healthcare system is warranted. OBJECTIVE: To evaluate the effects of VTE (deep vein thrombosis, pulmonary embolism, or both) occurring within the first 30 days of hospital discharge for total hip replacement (THR) or total knee replacement (TKR) surgery on inpatient costs, mortality, rehospitalization, and major bleeding within 1 year after initial hospitalization for THR or TKR surgery. METHODS: The Medicare Provider Analysis and Review (MEDPAR) file for calendar years 2005-2007 provided hospital discharge abstracts for the fee-for-service, acute-care hospitalizations of all Medicare recipients. All patients included in the analysis underwent THR (n = 51,108) or TKR (n = 115,627). VTE events were diagnosed within the first 30 days and within 1 year post discharge. Propensity score matching was used to control for differences in baseline characteristics in patients with and without VTE events. Total cost was measured as Medicare cost plus beneficiary out-of-pocket cost. RESULTS: VTE occurred in 0.74% of patients undergoing THR. For patients with VTE versus no VTE, mortality was higher (2.9% vs 0.4%, P < 0.001) and rehospitalization within 1 year was more frequent (51.9% vs 22.4%, P < 0.001), as were complications such as bleeding (11.2% vs 2.7%, P < 0.001). Risk-adjusted Medicare cost and total healthcare cost, including beneficiary cost share in 1 year, were significantly higher for VTE patients versus patients with no VTE ($18,929 vs $3763, P < 0.001). VTE occurred in 0.70% of patients undergoing TKR. For patients with VTE versus no VTE, mortality was higher (2.5% vs 0.15%, P < 0.001), and rehospitalization within 1 year was more frequent (48.7% vs 20.7%, P < 0.001), as were complications such as bleeding (13.7% vs 2.1%, P < 0.001). For TKR surgery, risk-adjusted total healthcare cost, including beneficiary cost share in 1 year, was significantly different for VTE versus no VTE ($17,996 vs $4358, P < 0.001). LIMITATIONS: Study limitations include a reliance on ICD-9-CM codes, which could be inaccurate, and the inability (1) to control for unmeasured confounders, such as surgeons' skills; (2) to include outpatient medical care costs; and (3) to ensure that all patients were enrolled continuously throughout the study period. CONCLUSIONS: VTE after THR or TKR is associated with higher mortality, rehospitalization, and bleeding within 1 year, compared with no VTE. Risk-adjusted total, Medicare, and beneficiary healthcare costs were significantly higher for both THR and TKR patients with VTE (P < 0.001).

Impact of postoperative venous thromboembolism on Medicare recipients undergoing total hip replacement or total knee replacement surgery.

PURPOSE: The impact of postoperative venous thromboembolism (VTE) during initial hospitalization for total hip replacement (THR) or total knee replacement (TKR) surgery was assessed. METHODS: Using Medicare Provider Analysis and Review files, patients who underwent THR, TKR, or hip fracture surgery from 2005 to 2007 were identified using appropriate procedure codes from the International Classification of Diseases, 9th Revision, Clinical Modification. Medicare managed care patients were excluded from the study. Eligible patients were classified as having had deep venous thrombosis (DVT), pulmonary embolism (PE), DVT and PE, or no VTE during their initial hospitalization. Risk adjustment was performed using propensity score matching. Medicare cost, cost to beneficiaries, and cost to primary payers were analyzed to determine risk-adjusted differences in outcome measures, including mortality, rehospitalization, bleeding, length of stay, and total health care expenditures related to VTE events. RESULTS: A total of 170,047 patients were identified. Postoperative VTE events occurred in 3,014 patients (1.77%) during their initial hospitalization. Risk-adjusted mortality rates were three to four times higher for patients with VTE compared with those without VTE. Patients with VTE were more likely to be rehospitalized and experience bleeding within 30 days. Risk-adjusted differences in annual mean cost, including Medicare cost and costs to beneficiaries and primary payers, were significantly greater for patients with VTE. CONCLUSION: Patients who developed VTE after THR or TKR had a higher likelihood of mortality, bleeding, and rehospitalization; were hospitalized longer; and incurred higher costs to Medicare, Medicare beneficiaries, and private payers compared with patients without VTE.

Analysis of venous thromboprophylaxis duration and outcomes in orthopedic patients.

BACKGROUND: Venous thromboembolism (VTE) following total hip replacement (THR) and total knee replacement (TKR) surgery imposes significant health and economic burden. OBJECTIVE: To examine the impact of thromboprophylaxis duration on deep vein thrombosis (DVT), pulmonary embolism (PE), total VTE (DVT and PE), and bleeding events among THR/TKR patients. METHODS: A retrospective study (April 1, 2004, to December 31, 2006) was conducted using a US health plan claims database linked to an inpatient database containing medication use. Outcomes were compared using χ2 tests; predictors of outcomes were analyzed using multivariate logistic regression. RESULTS: Of 3497 patients, 3195 (91%) received thromboprophylaxis for =1 day postsurgery. Most patients (67%) received short-duration (1-14 days) rather than extended-duration (>14 days) thromboprophylaxis. The incidence of thromboembolic and bleeding events was higher in those who received short-duration thromboprophylaxis: DVT (2.84% vs 1.24%; P = .0038), PE (1.12% vs 0.19%; P = .0052), total VTE (3.96% vs 1.43%; P <.0001), and major bleeding (1.68% vs 0.38%; P = .0011). Multivariate logistic regressions (adjusted for observed demographic and clinical characteristics) revealed similar results. Baseline comorbidity score was significantly associated with major bleeding; most of the bleeding events in those who received short-duration thromboprophylaxis occurred within the first 14 days. CONCLUSIONS: In this database analysis of patients who had undergone THR/TKR surgery, a large proportion of patients did not receive the minimum duration of thromboprophylaxis recommended by the guidelines. Extended-duration thromboprophylaxis was associated with a significantly lower risk of DVT, PE, and VTE compared with short-duration thromboprophylaxis.

Within-year variation in hospital utilization and its implications for hospital costs.

Variability in demand for hospital services may have important effects on hospital costs, but this has been difficult to examine because data on within-year variations in hospital use have not been available for large samples of hospitals. We measure daily occupancy in California hospitals and examine variation in hospital utilization at the daily level. We find substantial day-to-day variation in hospital utilization, and noticeable differences between hospitals in the amount of day-to-day variation in utilization. We examine the impact of variation on hospital costs, showing that increases in variance are associated with increases in hospital expenditures, but that the effects are qualitatively modest.
