Abstract

Objectives:

Few studies have characterized healthcare resource utilization among patients with idiopathic pulmonary fibrosis. The objective of this study is to assess healthcare resource utilization among patients with idiopathic pulmonary fibrosis as compared to members without this condition.

Methods:

Patients newly diagnosed with idiopathic pulmonary fibrosis were identified from a national administrative claims database (2006–2011) as having ≥2 claims with idiopathic fibrosing alveolitis, or ≥1 claim with idiopathic fibrosing alveolitis and ≥1 claim with post-inflammatory pulmonary fibrosis (earliest claim with idiopathic fibrosing alveolitis denoted the index date), a procedure of lung biopsy or high-resolution computed tomography within ±90 days of the index date, 12-month pre-index continuous enrollment, plus ≥2 confirmatory idiopathic fibrosing alveolitis diagnoses after the procedure. For each idiopathic pulmonary fibrosis patient, three members without the condition were matched by age/gender/region/payer type. Demographic/clinical characteristics were measured during the 1-year pre-index period. Healthcare resource utilization was assessed by quarter during 1-year pre- and post-index periods. Generalized estimating equation models controlling for patient characteristics were constructed to estimate adjusted post-index healthcare resource utilization.

Results:

In total, 1735 patients with idiopathic pulmonary fibrosis and 5205 without (mean age?=?71.5 years; 46.1% female) were included. Adjusted results revealed idiopathic pulmonary fibrosis patients were more likely to use healthcare resources than members without the condition 1-year post-index (number of hospitalizations, emergency room visits, and outpatients visits: 0.63 vs 0.31, 0.62 vs 0.48, and 5.7 vs 3.1 per person-year, respectively).

Conclusions:

Healthcare resource utilization is considerably higher among patients with idiopathic pulmonary fibrosis than members without the condition. Effective treatments for patients with idiopathic pulmonary fibrosis are needed to help reduce burden of healthcare resource use.  相似文献

Abstract

Background:

Pancreatic adenocarcinoma has few effective treatment options and poor survival. The objective of this study was to characterize treatment patterns and estimate the costs and resource use associated with its treatment in a commercially-insured US population.

Methods:

In this retrospective claims-based analysis, individuals ≥18 years old with evidence of pancreatic adenocarcinoma between January 1, 2001 and December 31, 2010 were selected from a managed care database. Treatment phase (either initial non-metastatic or metastatic) was determined using a claims-based algorithm. Patients in the pancreatic cancer population were matched 1:3 to a control population. Resource use (events/person-years), treatment patterns, and healthcare costs (per-patient per-month, PPPM) were determined during a variable length follow-up period (from first pancreatic cancer diagnosis to earliest of death, disenrollment, or study end).

Results:

In this study, 5262 pancreatic cancer patients were matched to 15,786 controls. Rates of office visits, inpatient visits, ER visits, and inpatient stays, and mean total all-cause healthcare costs PPPM ($15,480 vs $1001) were significantly higher among cancer patients than controls (all p?<?0.001). Mean inpatient costs were the single largest cost driver ($9917 PPPM). Also, mean total all-cause healthcare costs were significantly higher during the metastatic treatment phase vs the initial treatment phase of non-metastatic disease ($21,637 vs $10,358, p?<?0.001).

Conclusions:

These results indicate that pancreatic cancer imposes a substantial burden on the US healthcare system, and that treatment of more advanced disease is significantly more costly than initial treatment of non-metastatic disease.

Limitations:

Additional research is needed to validate the accuracy of the claims-based algorithms used to identify the treatment phase.  相似文献

Abstract

Objectives:

This study examines costs for postmenopausal women with hormone receptor positive (HR+) metastatic breast cancer (mBC).

Methods:

Data were obtained from the IHCIS National Managed Care Benchmark Database from 1/1/2001 to 6/30/2006. Women aged 55–63 years were selected for the study if they met the inclusion criteria, including diagnoses for breast cancer and metastases, and at least two fills for a hormone medication. Patients were followed from the onset of metastases until the earliest date of disenrollment from the health plan or 6/30/2006. Patient characteristics were examined at time of initial diagnoses of metastases, while costs were examined post-diagnosis of metastases and prior to receipt of chemotherapy (pre-chemotherapy initiation period) and from the date of initial receipt of chemotherapy until end of data collection (post-chemotherapy initiation period). Costs were adjusted to account for censoring of the data.

Results:

The study population consisted of 1,266 women; mean (SD) age was 59.05 (2.57) years. Pre-chemotherapy initiation, unadjusted inpatient, outpatient, and drug costs were $4,392, $47,731, and $5,511, while these costs were $4,590, $57,820, and $38,936 per year, respectively, post-chemotherapy initiation. After adjusting for censoring of data, total medical costs were estimated to be $55,555 and $70,587 in the first 12 months and 18 months, respectively in the pre-chemotherapy initiation period. Post-chemotherapy initiation period, 12-month and 18-month adjusted total medical costs were estimated to be $87,638 and $130,738.

Limitations:

The use of an administrative claims database necessitates a reliance upon diagnostic codes, age restrictions, and medication use, rather than formal assessments to identify patients with post-hormonal women with breast cancer. Furthermore, such populations of insured patients may not be generalizable to the population as a whole.

Conclusions:

These findings suggest that healthcare resource use and costs – especially in the outpatient setting – are high among women with HR+ metastatic breast cancer.  相似文献

Abstract

Objective:

To estimate the economic burden of multiple sclerosis (MS) in Turkey, including the relapses and disease severity, and to evaluate the quality-of-life of MS patients.

Methods:

The Treatment Experience, Burden and Unmet Needs (TRIBUNE) study was a multi-national, cross-sectional, retrospective, burden-of-illness survey. Total costs were calculated using unit costs derived from price lists or published literature, where relevant, and inflated to 2011 TL prices.

Results:

A total of 295 MS patients (74% females) were included in the analysis. The population had a mean age of 36 years; 73% had the relapsing–remitting form. Mean Expanded Disability Status Scale (EDSS) score was 2.2. Twenty-two per cent of the MS patients required hospitalization in the past year and spent an average of 29.2 days/year in hospital. These values were 43% and 5.6 days for the outpatients, respectively. Total cost per patient/year was 18,700 TL (Turkish Lira). Total costs for patients with mild, moderate, and severe disability were 15,418 TL, 26,002 TL, and 44,208 TL per patient/year, respectively. The mean EuroQol 5D scores in the same groups were 0.73, 0.52, and 0.05, respectively.

Conclusions:

Multiple sclerosis imposes a significant economic burden on patients and society in Turkey.  相似文献

Abstract

Objectives:

Glycemic control, measured by HbA1c, is well known to be a risk marker for long-term costly diabetes-related complications. The relationship between HbA1c and short-term costs is unclear. This study investigates how HbA1c is correlated to short-term diabetes-related medical expenses.

Methods:

Patients with diabetes with an HbA1c reading ≥6% between April and September 2007 were identified from a large US managed-care organization. Healthcare utilization data was obtained during the subsequent 12-month period. Multivariate analyses were performed to estimate the correlation between HbA1c and diabetes-related healthcare costs.

Results:

In all, 34,469 and 1,837 patients with type 2 and type 1 diabetes, respectively, were identified with an HbA1c reading ≥6% (mean HbA1c: 7.4% and 7.9%). The majority of patients with type 1 diabetes were treated with insulin, while most patients with type 2 diabetes were treated with metformin. The multivariate analysis showed that several characteristics, including HbA1c, significantly correlate with diabetes-related medical costs for both patients with type 1 and type 2 diabetes. A 1-percentage-point increase in HbA1c will, on average, lead to a 6.0% and 4.4% increase in diabetes-related medical costs for type 1 and type 2 diabetes, respectively. This corresponds to an annual cost increase of $445 and $250 for patients with type 1 and type 2 diabetes, respectively.

Limitations:

Retrospective data analyses inherently associated with selection bias which can only partly be adjusted by statistical techniques. Furthermore, the study population is not necessarily representative of the general population and there can be isolated coding or data errors in the dataset.

Conclusions:

These results suggest that tighter glycemic control is associated with short-term cost benefits for patients with diabetes. This supplements conventional wisdom that HbA1c affects risk of long-term complications and long-term costs.  相似文献

Abstract

Objective:

The primary objective of this study was to quantify the differences in the prevalence rate and costs of hospital medical errors between the general population and an elderly population aged ≥65 years.

Methods:

Methods from an actuarial study of medical errors were modified to identify medical errors in the Premier Hospital Database using data from 2009. Visits with more than four medical errors were removed from the population to avoid over-estimation of cost. Prevalence rates were calculated based on the total number of inpatient visits.

Results:

There were 3,466,596 total inpatient visits in 2009. Of these, 1,230,836 (36%) occurred in people aged ≥ 65. The prevalence rate was 49 medical errors per 1000 inpatient visits in the general cohort and 79 medical errors per 1000 inpatient visits for the elderly cohort. The top 10 medical errors accounted for more than 80% of the total in the general cohort and the 65+ cohort. The most costly medical error for the general population was postoperative infection ($569,287,000). Pressure ulcers were most costly ($347,166,257) in the elderly population.

Limitations:

This study was conducted with a hospital administrative database, and assumptions were necessary to identify medical errors in the database. Further, there was no method to identify errors of omission or misdiagnoses within the database.

Conclusions:

This study indicates that prevalence of hospital medical errors for the elderly is greater than the general population and the associated cost of medical errors in the elderly population is quite substantial. Hospitals which further focus their attention on medical errors in the elderly population may see a significant reduction in costs due to medical errors as a disproportionate percentage of medical errors occur in this age group.  相似文献

Abstract

Objective:

The 21-gene assay (Oncotype DX Breast Cancer Test (Genomic Health Inc., Redwood City, CA)) is a well validated test that predicts the likelihood of adjuvant chemotherapy benefit and the 10-year risk of distant recurrence in patients with ER+, HER2? early-stage breast cancer. The aim of this analysis was to evaluate the cost-effectiveness of using the assay to inform adjuvant chemotherapy decisions in Germany.  相似文献

Aims: Muscle weakness (MW)-attributable healthcare resource utilization (HCRU) and costs in patients with chronic obstructive pulmonary disease (COPD) have not been well-characterized in US insurance claims databases. The primary objective of this study was to estimate HCRU in patients with evidence of COPD with and without MW diagnosis codes.

Materials and methods: This retrospective analysis used the MarketScan® Commercial Claims and Encounters and Medicare Supplemental and Coordination of Benefits databases. Between January 2007 and March 2016, we identified patients aged ≥40 years with diagnosis codes for COPD (≥1 emergency department or inpatient claim or ≥2 outpatient claims within 1 year). The cohort was divided into patients with and without ≥1?MW diagnosis code. Propensity score matching was used to generate pairs of patients with and without MW (1:1). Multivariable regression analyses were used to estimate adjusted incremental costs and utilization attributable to the presence of MW diagnosis codes among patients with COPD.

Results: Of 427,131 patients who met the study inclusion criteria, 14% had evidence of MW. After matching, 107,420 unique patients remained equally distributed across MW status. Patients with MW diagnosis codes had greater predicted annual HCRU, $2,465 greater total predicted annual COPD-related costs, and $15,179 greater total all-cause costs than those without MW diagnosis codes. Overall, <1% of patients received COPD-related pulmonary rehabilitation services.

Limitations: Study limitations include the potential for undercoding of MW and lack of information on severity of MW in claims data.

Conclusion: The presence of MW diagnosis codes yielded higher HCRU in this COPD population and suggests that the burden of MW affects both all-cause and COPD-related care. However, utilization of pulmonary rehabilitation, a known effective treatment for MW, remains low. Future research should expand on our results by assessing data sources that allow for clinical confirmation of MW among patients with COPD.  相似文献

Abstract

Objective:

To compare the health care costs of patients with metastatic colorectal cancer (mCRC) who received second-line treatment with Avastin (bevacizumab) versus Erbitux (cetuximab), from the third-party payer’s perspective.

Methods:

Patients with mCRC were selected from the PharMetrics claims database if they received second-line therapy containing either bevacizumab (second-line bevacizumab cohort) or cetuximab (second-line cetuximab cohort). Six-month costs following second-line therapy start date and average monthly healthcare costs while on second-line therapy (in 2009 US$) were calculated and compared between the two groups.

Results:

A total of 2188 patients with mCRC who met the eligibility criteria were included in the analysis, including 1808 patients receiving bevacizumab and 380 patients receiving cetuximab in second-line treatment. Demographic and baseline characteristics were similar between the two groups. Patients’ mean age was 61 years and 56% were males. In second-line treatment, bevacizumab was commonly used with oxaliplatin (43.5%) and irinotecan-based regimens (40.4%), whereas cetuximab was commonly used with irinotecan-based regimens (68.2%). Bevacizumab patients had significantly lower total all-cause healthcare costs than cetuximab patients (adjusted difference: –$10,231, p?=?0.020), and lower medical costs (–$10,796, p?=?0.012) during the 6 months following second-line therapy initiation. Approximately half of the difference in total all-cause healthcare costs was attributable to the lower chemotherapy and targeted therapy costs (–$5635, p?=?0.032) of bevacizumab patients than those of cetuximab patients. While on second-line therapy, bevacizumab patients also had lower average monthly all-cause healthcare costs than cetuximab patients.

Limitations:

Second-line treatment in the current study was defined based on changes in mCRC medications, not based on disease progression due to the limited clinical information available in claims.

Conclusion:

The use of bevacizumab in second-line therapy was associated with significantly lower healthcare costs in mCRC patients, compared to the use of cetuximab.  相似文献

Objectives: To describe the management and costs associated with G-CSF therapy in cancer patients in France.

Methods: This study analyzed a representative random population sample from the French national healthcare insurance database, focusing on 1,612 patients with hematological or solid malignancies who were reimbursed in 2013 or 2014 for at least one G-CSF treatment dispensed in a retail pharmacy. Patient characteristics and treatment costs were analyzed according to the type of cancer. Then the costs and characteristics of patients associated with the use of different G-CSF products were analyzed in the sub-set of breast cancer patients.

Results: The most frequent malignancies in the database population were breast cancer (23.3%), hematological malignancies (22.2%), and lung cancer (12.4%). The reimbursed G-CSF was pegfilgrastim in 34.1% of cases, lenograstim in 26.7%, and filgrastim in 17.9%. More than one G-CSF product was reimbursed to 21.3% of patients. The total annual reimbursed health expenses per patient, according to the type of G-CSF, were €27,001, €24,511, and €20,802 for patients treated with filgrastim, lenograstim, and pegfilgrastim, respectively. Ambulatory care accounted for, respectively, 35%, 38%, and 41% of those costs. In patients with breast cancer, ambulatory care cost was €7,915 with filgrastim, €7,750 with lenograstim, and €6,989 with pegfilgrastim, and the respective cost of G-CSF was €1,733, €1,559, and €3,668.

Conclusion: All available G-CSF products have been shown to be effective in cancer patients, and both daily G-CSFs and pegylated G-CSF are recommended in international guidelines. Nevertheless, this analysis of G-CSF reimbursement indicates that the choice of product can markedly affect the total cost of ambulatory care.  相似文献

Abstract

Aims: The study evaluated the real-world cost of treatment in multiple sclerosis (MS) patients initiating infused disease-modifying-therapies (DMT) in the United States.

Materials and Methods: This retrospective cohort study using administrative claims data included adult patients with MS initiating index infusion DMT (ocrelizumab (OCR), natalizumab (NTZ) or alemtuzumab (ATZ)) from April 2017–September 2018 with 6-months pre/12-months post-index continuous enrollment. The primary cohort included patients who had prescribed annual dosing visits indicated by the approved product label (PL): 3 OCR, 5 ATZ, and 12–13 NTZ infusion visits within the first year of initiation. Annual treatment cost was the sum of all costs on index DMT infusion visit dates. Costs were summarized for a primary and secondary cohort of patients receiving additional doses than prescribed in PL (>3 OCR, >5 ATZ, and >13 NTZ infusion visits); and an overall cohort of patients who met minimum required annual dose (≥3 OCR, ≥5 ATZ, and ≥12 NTZ), further stratified by insurance type.

Results: For patients in the primary cohort (123 OCR, 18 ATZ, and 48 NTZ), mean (standard-deviation) annual cost of treatment with OCR, ATZ, and NTZ cohorts was $72,066 ($34,480), $121,053 ($51,097) and $93,777 ($38,815), respectively. Among patients initiating OCR and NTZ, 15 and 6% respectively, had additional infusion visits leading to greater costs. Mean annual costs of index infusion DMT treatment in the overall cohort (162 patients treated with OCR, 18 with ATZ, 56 with NTZ) were $80,582, $121,053, and $93,807, respectively. The mean costs for commercial enrollees were higher than those for MAPD enrollees.

Limitations: Small sample size, limited population generalizability, and cost-reduction for ATZ beyond the second year need to be accounted for.

Conclusions: Real-world infusion DMT treatment costs for commercially insured patients were higher than perceived expenditures based on wholesale acquisition cost and administration costs via a physician-fee schedule. Consideration of real-world costs in cost-effectiveness and treatment/coverage decisions is needed.  相似文献

Abstract

Objective: Few studies have examined the costs associated with differing first-line chemotherapy regimens in patients with metastatic breast cancer (MBC). This study compares the relative cost impact of women starting first-line chemotherapy with capecitabine versus taxanes.

Methods: Women receiving first-line chemotherapy for MBC from 1998 to 2002 were identified from a hybrid North Carolina Medicaid-claims-tumour registry linked database and Medicare records, and were followed through to 2005 with claims data. Statistical t- and chi-square tests were used to compare baseline characteristics between patients who received first-line chemotherapy with capecitabine versus taxanes. Projected mean costs for 12 months continuous eligibility were estimated using an ordinary least squares linear regression. Overall cost impact of capecitabine after start of therapy was then examined using a multivariate log-linear regression model.

Results: While patients starting taxanes had significantly lower total costs in the pre-index year than patients starting capecitabine (mean: $20,042 vs. $35,538, p<0.001), in the post-index year, the patients on taxanes experienced significantly higher healthcare utilisation and associated costs compared to patients on capecitabine (mean: $43,353 vs. $35,842, p=0.0089). The differences were primarily attributable to lower expenses in chemotherapy related claims and fewer visit days to outpatient settings for patients on capecitabine. After adjustment with propensity scores and other confounders, the capecitabine group was associated with 32% lower healthcare costs compared to the taxane group (p=0.0001).

Conclusions: In this population-based study, women who received capecitabine as first-line treatment for MBC had significantly lower costs compared to women starting taxane therapy.  相似文献

Abstract

Objectives:

There is a paucity of recent data on breast cancer costs, particularly on the burden of chemotherapy. The present study was designed to estimate resource use and costs associated with the current standard of care for adjuvant chemotherapy for breast cancer.

Methods:

Costs and resource use were assessed by retrospective analysis of medical records at a single comprehensive cancer care center, Hôpital Tenon, Paris, France. Data were extracted from files of female patients having undergone surgical resection of breast cancer between January–July 2010. Patients were included if they received chemotherapy at the hospital and had medical records available. Patients were followed from the start of adjuvant chemotherapy (including pre-chemotherapy) to the end of treatment. Costs were collected for each resource use item from a societal perspective using standard, published sources and expressed in 2011 Euros (€). Limitations of the analysis included the single-center study design and the use of pre-defined questionnaires on resource use (which may conservatively estimate costs).

Results:

A total of 62 patients were included in the study with a mean age of ~54 years. Most patients had stage II (50.8%) or stage III (40.7%) disease. Anthracycline plus taxane-based chemotherapy regimens were most commonly prescribed (77% of patients). Mean cost of adjuvant chemotherapy was estimated to be ~€15,740 per patient from a societal perspective. The acquisition costs of chemotherapy agents were responsible for 26% of the total, with lost productivity (27%), chemotherapy administration (19%), and adverse events (16%) also contributing substantially.

Conclusions:

Evaluation of costs in patients with non-metastatic breast cancer in France has shown that the costs of adjuvant chemotherapy are substantial. The main components of total cost were the cost of chemotherapy agents, lost productivity, chemotherapy administration, and management and prevention of adverse events.  相似文献

Abstract

Objective:

To explore treatment patterns and resource utilization and cost for subjects with pulmonary arterial hypertension (PAH).

Research design:

Retrospective claims database analysis of 706 patients with PAH enrolled in a large, geographically diverse US managed-care organization.

Results:

In the final sample of PAH patients treated with bosentan (n?=?251) or sildenafil (n?=?455), average age was 57 years, 86% of patients were commercially insured, and 52% of patients were male. Gender distribution varied significantly across subgroups, with a lower proportion of males in the bosentan (30%) subgroup compared with the sildenafil group (64%) (p?<?0.001). Average baseline Charlson comorbidity score was 2.4. Average numbers of fills per month were 0.8 and 0.4 for bosentan and sildenafil patients, respectively (p?<?0.001). Over 80% of patients received only one PAH treatment in the first 90 days following the index date, with 28% of bosentan and 13% of sildenafil patients receiving combination therapy (p?<?0.001). Over one-third of bosentan patients and one-quarter of sildenafil patients experienced a dose increase in the follow-up period (p?=?0.009). Sixteen percent of sildenafil patients experienced a dose decrease in the follow-up period, while a smaller proportion of patients receiving bosentan (4%) experienced a dose decrease (p?<?0.001). On average, number of PAH-related per subject per month (PSPM) inpatient stays and emergency department visits and PSPM length of inpatient stays were statistically similar between the subgroups. PAH-related PSPM healthcare costs were high for both subgroups, with average monthly costs of $5,332 and $3,632 among bosentan and sildenafil patients, respectively (p?=?0.003). Differences in total costs were driven mainly by differences in pharmacy expenditures.

Conclusions:

Of the oral agents approved for treating PAH at the time of this study, sildenafil was most commonly prescribed as index therapy and was also associated with the lowest costs, largely due to significantly lower pharmacy costs. This study is characterized by limitations inherent to claims database analyses, such as the potential for coding errors and lack of information on whether a drug was taken as prescribed. Furthermore, PAH severity (WHO functional class) was not assessed.  相似文献

Abstract

Objective:

The safety and efficacy of the GLP-1 receptor agonists exenatide BID (exenatide) and liraglutide for treating type 2 diabetes mellitus (T2DM) have been established in clinical trials. Effective treatments may lower overall treatment costs. This study examined cost offsets and medication adherence for exenatide vs liraglutide in a large, managed care population in the US.

Methods:

This was a retrospective cohort analysis comprising adult patients with T2DM who initiated exenatide or liraglutide between 1/1/2010 and 6/30/2010 and had 6 months pre-index and post-index continuous eligibility. Patients were propensity score-matched to controls for baseline differences. Medication adherence was measured by proportion of days covered (PDC). Paired t-test and McNemar’s test were used to compare outcomes.

Results:

Matched exenatide and liraglutide cohorts (n?=?1347 pairs) had similar average total 6-month follow-up costs ($6688 vs $7346). However, exenatide patients had significantly lower mean pharmacy costs ($2925 vs $3272, p?<?0.001). Among liraglutide patients, patients receiving the 1.8?mg dose had significantly higher average total costs compared to those receiving the 1.2?mg dose ($8031 vs $6536, p?=?0.026), with higher mean pharmacy costs in the 1.8?mg cohort ($3935 vs $3146, p?<?0.001). There were no significant differences in inpatient or outpatient costs or medication adherence between groups (mean PDC: exenatide 56% vs liraglutide 57%, p?=?0.088).

Limitations:

The study assumed that all information needed for case classification and matching of cohorts was present and not differential across cohorts. The study did not control for covariates that were unavailable, such as HbA1c and duration of diabetes.

Conclusions:

Patients initiating exenatide vs liraglutide for T2DM had similar medication adherence and total healthcare costs; however, exenatide patients had significantly lower total pharmacy costs. Patients prescribed 1.8?mg liraglutide had significantly higher costs compared to those on 1.2?mg.  相似文献

Summary

The introduction of a new class of drugs, the taxoids, has dramatically improved the outlook for patients with advanced, metastatic breast cancer. Second-line monotherapy with the most effective taxoid, docetaxel, in patients with anthracycline-resistant metastatic breast cancer, shows an overall response rate up to 55% in this patient population. Increased response rate is associated with improved quality of life for these patients.

We carried out a cost analysis to determine the economic benefits of being in a response state compared with the other health states associated with advanced breast cancer: stable, progressive or terminal disease.

We found that the cost of care for responders is 40% of that for early progressive disease and just over a third of that for late progressive disease. The costs associated with stable disease are only a little less than those for progressive disease, and are more than double the costs for patients who have responded to chemotherapy. The costs during terminal disease are the highest, and are more than nine times those associated with caring for responders.

Our findings confirm other studies which demonstrate that the cost of chemotherapy can be offset against the reduction in costs incurred for patients who remain in healthier states for longer. The key parameter determining the economic efficiency of treatments for advanced breast cancer is response rate.  相似文献

This paper examines arguments by activists and economists surrounding attempts to establish minimum wages for women in the United States in the Progressive Era. In particular, the paper focuses on analyses based on Beatrice and SidneyWebbs' argument that industries paying less than a living wage were "parasitic" on the society, a net drain on macro-efficiency. This analysis, widely accepted among economists of the time, viewed women as particularly vulnerable workers facing labor markets that were institutionally constructed and predatory. Unequal gender roles, employer power, and the absence of collective bargaining could all result in wages that were socially unacceptable as well as economically nonoptimal. These debates offer insights for modern feminist wage theories, and for current living wage campaigns.  相似文献
