Trends in Health Care Utilization and Expenditures in the United States Across 5 Decades: 1977-2017.

BACKGROUND: Health care expenditures in the United States are high and rising, with significant increases over the decades. The delivery, organization, and financing of the health care system has evolved over time due to technological innovation, policy changes, patient preferences, altering payment mechanisms, shifting demographics, and other factors. OBJECTIVE: The objective of this study was to examine trends over time in health care utilization and expenditures in the United States. RESEARCH DESIGN: This analysis employs descriptive statistics to examine 5 decades of health care utilization and expenditure data from the Agency for Healthcare Research and Quality (AHRQ) for 1977-2017. MEASURES: Measures include utilization and expenditures (not charges) for inpatient, emergency department, outpatient physician, outpatient nonphysician, office-based physician, dental, and out-of-pocket retail prescription drugs. RESULTS: We demonstrate that while health care expenditures have increased significantly overall and by type of care, utilization trends are less pronounced. The population of the United States grew 53% between 1977 and 2017, while annual total expenditures on health care increased by 208%. Amidst attention to out-of-pocket exposure for unexpected medical care bills, out-of-pocket payments for care have declined from 32% in 1977 to 12% in 2017 but increased in amount. CONCLUSIONS: This article provides the first extended snapshot of the dynamics of health care utilization and expenditures in the United States. Aspects of health care are much different today than in previous decades, yet the inpatient setting still dominates the expenditures.

Acute dental infections managed in an outpatient parenteral antibiotic program setting: prospective analysis and public health implications.

BACKGROUND: The number of Acute Dental Infections (ADI) presenting for emergency department (ED) care are steadily increasing. Outpatient Parenteral Antibiotic Therapy (OPAT) programs are increasingly utilized as an alternative cost-effective approach to the management of serious infectious diseases but their role in the management of severe ADI is not established. This study aims to address this knowledge gap through evaluation of ADI referrals to a regional OPAT program in a large Canadian center. METHODS: All adult ED and OPAT program ADI referrals from four acute care adult hospitals in Calgary, Alberta, were quantified using ICD diagnosis codes in a regional reporting system. Citywide OPAT program referrals were prospectively enrolled over a five-month period from February to June 2014. Participants completed a questionnaire and OPAT medical records were reviewed upon completion of care. RESULTS: Of 704 adults presenting to acute care facilities with dental infections during the study period 343 (49%) were referred to OPAT for ADI treatment and 110 were included in the study. Participant mean age was 44 years, 55% were women, and a majority of participants had dental insurance (65%), had seen a dentist in the past six months (65%) and reported prior dental infections (77%), 36% reporting the current ADI as a recurrence. Median length of parenteral antibiotic therapy was 3 days, average total course of antibiotics was 15-days, with a cumulative 1326 antibiotic days over the study period. There was no difference in total duration of antibiotics between broad and narrow spectrum regimes. Conservative cost estimate of OPAT care was $120,096, a cost savings of $597,434 (83%) compared with hospitalization. CONCLUSIONS: ADI represent a common preventable cause of recurrent morbidity. Although OPAT programs may offer short-term cost savings compared with hospitalization, risks associated with extended antibiotic exposures and delayed definitive dental management must also be gauged.

Evaluation of the telephone and clinical NHS urgent dental service in Sheffield.

OBJECTIVE: Evaluate an NHS in- and out-of-hours urgent dental service (UDS) including both a telephone triage provider (TTP) and a sole clinical provider (CP) using a quality framework. BASIC RESEARCH DESIGN: Analysis of activity and patient experience data. MAIN OUTCOME MEASURES: Ratio of volume of services to activity provided; distance and time travelled; appropriateness of referrals and treatments; equity of utilisation; patient experience; cost per patient. RESULTS: Almost all calls (96.6%) to the TTP were answered within 60 seconds and of people referred to the CP 96.0% needed treatment. Proportionately more people from deprived areas used the TTP. Highest utilisation of the TTP was by people aged 20 to 44 years and lowest was by people over 54 years. Cost per patient utilising the TTP was £5.06. Of the available appointments provided by the CP, 90.9% were booked the TTP. Travel time to the CP was less than 30 minutes for 78.0% of patients. Of treatments provided, 77.9% were clinical interventions and 18.1% were prescription only. Proportionately more people from deprived areas attended the CP. Highest utilisation was by people aged 20 to 44 years and lowest by people over 54 years. Nearly half (47.0%) of those attending reported they did not have a dentist. There was a high level of patient satisfaction. Cost per course of treatment at the CP was £67.41. CONCLUSION: Overall the UDS provided a high quality service in line with Maxwell's dimensions of quality. Timely advice and treatment was provided with high levels of patient satisfaction with the CP. Comparison with other urgent dental service models would determine the relative efficiency of the UDS.

[Payment of out-patient dental service according to tariffs in obligatory insurance system]. / Oplata po tarifam ambulatornoi meditsinskoi pomoshchi v sisteme OMS po profilyu «Stomatologiya¼.

Cost price of dental services in system of obligatory medical insurance is higher two fold than officially determined tariffs. Costs of the same services in medical organizations of the same federal region in Russia tend to varyMeasures directed at the stimulation of reduction of expenses connected with the keep of those medical organizations that have increased expenses (compared to other medical organizations) should be considered.

[Out-patient dental service visit costs in obligatory insurance system].

Significant vary of cost price is being observed in the medical organizations not only in the different subjects of the Russian Federation, but in the same federal region of the Russian Federation. So in the medical organizations of the Central Federal Region the fourfold difference of cost price of attendance with the prophylactic aim is observed. These facts make the planning of financial recourses difficult by elaborating the plans of state tasks and programs of state guarantees in general.

Treatment Capabilities of Postgraduate Dental Trainees at Tokyo Dental College Suidobashi Hospital Based on Dental Services Income.

As of fiscal year 2006, it became compulsory for all newly licensed dentists in Japan to undergo a year of practical training at one of the designated training facilities found throughout the country as part of their postgraduate programs. The goal of this training is for the trainees to acquire diagnostic and therapeutic skills. While officially trainees, they are nonetheless regarded as members of staff. Clinical training emphasizes improving both technical skills and theoretical knowledge. However, taking on such trainees is sometimes considered unprofitable, as work productivity is claimed to be low. The purpose of this study was to compare work outcomes and income generated between trainees and part-time dentists working at the Tokyo Dental College Suidobashi Hospital. The part-time dentists comprised clinical instructors and dentists responsible for outpatients. Postgraduate dental trainees also generally conduct dental treatment for outpatients. Therefore, part-time dentists were considered the most suitable for a control group. No significant difference was observed in the total number of patients seen by either group by the final term of clinical training. Furthermore, no significant difference was observed in insurance-based dental treatment unit income (insured care unit income) per patient between the two groups from the mid-term period of training onwards. These results suggest that, although the trainees were less efficient in terms of time taken to provide a diagnosis and treatment, their performance was almost equal when viewed from the viewpoint of insured care provided. Taken together, this suggests that time-related care efficiency must be increased and specific training policies and strategies developed to improve the work productivity of dental trainees.

Cost analysis of periodontitis management in public sector specialist dental clinics.

BACKGROUND: The objective of this paper is to quantify the cost of periodontitis management at public sector specialist periodontal clinic settings and analyse the distribution of cost components. METHODS: Five specialist periodontal clinics in the Ministry of Health represented the public sector in providing clinical and cost data for this study. Newly-diagnosed periodontitis patients (N = 165) were recruited and followed up for one year of specialist periodontal care. Direct and indirect costs from the societal viewpoint were included in the cost analysis. They were measured in 2012 Ringgit Malaysia (MYR) and estimated from the societal perspective using activity-based and step-down costing methods, and substantiated by clinical pathways. Cost of dental equipment, consumables and labour (average treatment time) for each procedure was measured using activity-based costing method. Meanwhile, unit cost calculations for clinic administration, utilities and maintenance used step-down approach. Patient expenditures and absence from work were recorded via diary entries. The conversion from MYR to Euro was based on the 2012 rate (1€ = MYR4). RESULTS: A total of 2900 procedures were provided, with an average cost of MYR 2820 (€705) per patient for the study year, and MYR 376 (€94) per outpatient visit. Out of this, 90% was contributed by provider cost and 10% by patient cost; 94% for direct cost and 4% for lost productivity. Treatment of aggressive periodontitis was significantly higher than for chronic periodontitis (t-test, P = 0.003). Higher costs were expended as disease severity increased (ANOVA, P = 0.022) and for patients requiring surgeries (ANOVA, P < 0.001). Providers generally spent most on consumables while patients spent most on transportation. CONCLUSIONS: Cost of providing dental treatment for periodontitis patients at public sector specialist settings were substantial and comparable with some non-communicable diseases. These findings provide basis for identifying potential cost-reducing strategies, estimating economic burden of periodontitis management and performing economic evaluation of the specialist periodontal programme.

A retrospective study of patients' out-of-pocket costs for granulocyte colony-stimulating factors.

OBJECTIVE: With rising healthcare costs, there is an increasing concern with the burden of out-of-pocket costs on cancer patients. This study examined patients' out-of-pocket expenditures for granulocyte colony-stimulating factors, pegfilgrastim and filgrastim, which are given to cancer patients receiving myelosuppressive chemotherapy and have been shown to decrease the incidence of febrile neutropenia. METHODS: Adult patients who received chemotherapy and granulocyte colony-stimulating factors in the outpatient setting in the United States between January 2007 and June 2010 were evaluated using medical and pharmacy claims data from two healthcare data sources, the MarketScan(®) Commercial and Medicare Supplemental Databases and the HealthCore Integrated Research Database(SM). The distribution of out-of-pocket costs for granulocyte colony-stimulating factors per patient and per administration was described for each quarter. Longitudinal analyses of out-of-pocket costs for granulocyte colony-stimulating factors were also performed for patients with continuous health plan eligibility during each calendar year from 2007 to 2009. RESULTS: The pattern of out-of-pocket expenditures for pegfilgrastim and filgrastim was generally consistent between the databases and over time. On average, about 65%-75% of patients had zero quarterly out-of-pocket costs for granulocyte colony-stimulating factors. Across the years, the mean quarterly out-of-pocket costs per patient were $100-$150 and $50-$80 for pegfilgrastim and filgrastim, respectively. The mean quarterly out-of-pocket costs for granulocyte colony-stimulating factors per administration were $40-$70 and $8-$10, respectively. CONCLUSION: In this retrospective analysis of medical and pharmacy claims data, most patients who received chemotherapy and granulocyte colony-stimulating factors in 2007 to 2010 had incurred no quarterly out-of-pocket costs associated with G-CSF use.

Cost comparison of outpatient treatment with granulocyte colony-stimulating factors (G-CSF) in Germany.

BACKGROUND: Granulocyte colony-stimulating factors (G-CSF), are available for prevention of neutropenia and reduction of its complications in cytostatic chemotherapy. The purpose of this analysis was to determine the consumption rates for various G-CSF and to compare outpatient medication costs per patient and treatment cycle. METHODS: Prescription data of statutory health insurance members in Germany (IMS®LRx database) with G-CSF prescriptions between January 2008 and July 2010 were evaluated. A period of observation of at least 6 months prior to and after the G-CSF prescription was required. RESULTS: Prescription data of 8,726 patients treated with original filgrastim, 4,240 with biosimilar filgrastim, 6,456 with lenograstim, and 9,939 with pegfilgrastim were analyzed. The regression model showed statistically significant costreducing effects per cycle for treatment with lenograstim compared with non-lenograstim (-0.47 vs. original filgrastim; -0.15 vs. biosimilar filgrastim; -1.04 vs. pegfilgrastim; each p < 0.0001). This result has been adjusted for patient age, gender, number of injections, and prescribing specialist group. CONCLUSIONS: Treatment with the original preparation lenograstim is significantly cheaper compared to the other two original drugs and biosimilar. The costs of G-CSF treatment with the original preparation lenograstim and the filgrastim biosimilars are in a similar range, but with a significantly lower cost for lenograstim. Compared to their reference product the biosimilars thus show a cost advantage.

Use of selected ambulatory dental services in Taiwan before and after global budgeting: a longitudinal study to identify trends in hospital and clinic-based services.

BACKGROUND: The Taiwan government adopted National Health Insurance (NHI) in 1995, providing universal health care to all citizens. It was financed by mandatory premium contributions made by employers, employees, and the government. Since then, the government has faced increasing challenges to control NHI expenditures. The aim of this study was to determine trends in the provision of dental services in Taiwan after the implementation of global budgeting in 1998 and to identify areas of possible concern. METHODS: This longitudinal before/after study was based on data from the National Health Insurance Research Database from 1996 to 2001. These data were subjected to logistic regression analysis. Linear regression analysis was used to examine changes in delivery of specific services after global budgeting implementation. Utilization of hospital and clinic services was compared. RESULTS: Reimbursement for dental services increased significantly while the number of visits per patient remained steady in both hospitals and clinics. In hospitals, visits for root canal procedures, ionomer restoration, tooth extraction and tooth scaling increased significantly. In dental clinics, visits for amalgam restoration decreased significantly while those for ionomer restoration, tooth extraction, and tooth scaling increased significantly. After the adoption of global budgeting, expenditures for dental services increased dramatically while the number of visits per patient did not, indicating a possible shift in patients to hospital facilities that received additional National Health Insurance funding. CONCLUSIONS: The identified trends indicate increased utilization of dental services and uneven distribution of care and dentists. These trends may be compromising the quality of dental care delivered in Taiwan.

Relationship between subjective assessment of oral health and medical expenses in community-dwelling elderly persons.

OBJECTIVES: The increasing medical expenses of elderly persons in Japan's rapidly ageing society have become a major concern. It is therefore important to elucidate the factors associated with such escalation. Here, we focused on the relationship between subjective self-assessment of oral health, as an index of general health, and medical expenses (excluding dental repair) under the hypothesis that oral health contributes to general medical expenses. Several studies have shown that oral health status is correlated with general health status among elderly persons. We speculated that oral health status might show a relation with medical costs among elderly persons. However, few studies have investigated this relationship to date. MATERIALS AND METHODS: Participants were 259 elderly subjects (range: 65-84 years; 120 men, 139 women) residing independently. Subjective assessment of oral health was evaluated by their responses ('Good', 'Not good' and 'Not at all good') on a survey questionnaire. The correlation between subjective assessment of oral health and medical expenditure was analysed using Spearman's rank method, the Mann-Whitney U-test and the Kruskal-Wallis test. Medical expenses were used as the dependent variable in multinomial logistic regression analysis with background and intraoral factors as independent variables. RESULTS: A slight yet statistically significant correlation was observed between subjective assessment of oral health and outpatient treatment fees. CONCLUSION: The findings revealed that subjective assessment of oral health is significantly and independently related to the medical expenses of community-dwelling elderly persons after adjusting for social background, living environment and physical factors.

[Healthcare expenditure]. / Les dépenses de santé.

Healthcare expenditure is divided between medical infrastructure and individual patient management. Total healthcare costs in France amount to roughly 175 billion euros, financed through public health insurance (77%), private insurance (14%), and individual expenditure (9%). The principal expenditures are for hospitalization (44%), community medical, dental and paramedical care (28%), drugs (20%) and miscellaneous resources (8%). The main factors of rising costs are medical progress and aging. More controllable costs include healthcare provision, the level of reimbursement, public education and information, and physician training. France devotes 9.2% of its gross national product to healthcare, compared to 7-8% in Sweden, Germany and the United Kingdom, representing a diference of about 18 billion euros. In France there is a chronic imbalance between resources and expenditure, creating a cumulative budget deficit of about 100 billlion euros. Major efforts must be made to improve efficiency, and it will be necessary to choose between preserving our healthcare system or our financial system. If the latter is prioritized, healthcare will inevitably deteriorate.

Self-assessed masticatory ability and hospitalisation costs among the elderly living independently.

The escalating medical costs are a social problem in many countries. Masticatory ability is thought to be related to the general health conditions. The purpose of this study was to show relationships between self-assessed masticatory ability and medical costs among the elderly living independently in community. Data on background factors and self-assessed masticatory ability were collected from 702 Japanese elderly persons by questionnaires. An intra-oral examination was performed to examine the number of remaining teeth. Self-assessed masticatory ability was classified into one of three categories: ability to chew all kinds of food (Good), ability to chew only slightly hard food (Fair) or ability to chew only soft or pureed food (Poor). Data on the annual medical excluding dental costs were obtained from the Japanese National Health Insurance system. The Kruskal-Wallis test was used to examine differences in outpatient costs and hospitalisation costs among the three groups of self-assessed masticatory ability. Univariate unconditional logistic regression models and multivariate logistic regression models were used with medical costs as the dependent variable and self-assessed masticatory ability as the principal independent variable. A significant difference (P=0·039) in hospitalisation costs but not outpatient costs was found among the three groups of self-assessed masticatory ability. The multivariate logistic regression analysis showed that severely impaired masticatory ability (Poor) was significantly related to higher costs of hospitalisation. Self-assessed impairment of masticatory ability may be a significant and independent indicator of higher costs of hospitalisation among community-dwelling elderly persons.

The Result of Treatment of Deep Neck Infection in Patients Referred According to Public Health System.

There are many factors that result in the treatment of deep neck infection (DNI). This study aims to compare the results of DNI treatment between referred and walk-in patients. This retrospective cohort study reviewed the data of 282 DNI patients. The peritonsillar abscesses and limited intraoral abscesses were excluded. The outcome of treatment such as duration of hospital stay, the expense of treatment, morbidity, and mortality were reviewed during staying in the hospital. A total of 282 patients were included in this study, there were 152 referred patients and 130 walk-in patients. Patients who were sent to have treatment results were not significantly different from those who had come directly to the hospital regardless of the length of stay, the cost of medical treatment, complications, and death due to complications with sepsis (P = .013). However, the referred patients exhibited a risk to have sepsis 1.1 times more than the patients who went straight to the medical specialists (univariate analysis risk ratio [RR]: 1.1, 95% confidence interval [CI]: 0.8-1.3; P = .620). The results were confirmed in the multivariate analysis after adjusting for age, gender, diabetes, chronic renal failure, cirrhosis, and dental care. It was found that the risk to have sepsis in the "refer in" group was 1.1 times more than the other group (multivariate analysis RR: 1.1, 95% CI: 0.8-1.3; P = .658). In conclusion, the results of treatment in referred patients were not different from walk-in patients. Deep neck infection patients at hospitals that do not have a specialized doctor will receive appropriate treatment because of the effective DNI referral system according to public health systems. However, in referred patients, sepsis should be maintained prior to delivery.

Retrospective audit of Taranaki children undergoing dental care under general anaesthetic from 2001 to 2005.

A retrospective audit of trends in day-stay treatment for dental caries at a New Zealand hospital dental unit showed that demand for treatment has risen. The annual number of children undergoing a GA increased by over 13%, although the average waiting time after the initial consultation decreased. The cost of treatment also dramatically increased with time, as the numbers and complexity of cases increased. The type of treatment under GA changed over the five years, with more extractions occurring over the course of the audit. Restorations were still the most common treatment item provided, although the use of SSC trebled in 2004 and 2005. Socio-economic status, sex and ethnic differences were observed, with more boys and Maori receiving GA care and having a higher number of extractions. These children were identified as being high users of other hospital services (such as the Emergency Department).

Intermittent Catheters for Chronic Urinary Retention: A Health Technology Assessment.

BACKGROUND: People with chronic urinary retention typically require intermittent catheterization. This review evaluates the effectiveness, safety, patient preference, cost-effectiveness, and budget impact of different types of intermittent catheter (IC). Specifically, we compared prelubricated catheters (hydrophilic, gel reservoir) and noncoated catheters, as well as their single use versus reuse (multiple use). METHODS: We performed a systematic literature search and included randomized controlled trials, cohort, and case-control studies that examined any type of single-use versus multiple-use IC, hydrophilic single-use versus noncoated single-use, or gel reservoir single-use versus noncoated single-use. The outcomes of interest were symptomatic urinary tract infection (UTI), hematuria, other serious adverse events, and patient satisfaction. The quality of the body of evidence was examined according to the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) Working Group criteria. We also completed an economic evaluation, using the perspective of the Ontario Ministry of Health and Long-Term Care, to determine the cost-effectiveness of various intermittent catheters used in Ontario. We determined the budget impact of fully and partially funding various intermittent catheters for outpatients with chronic urinary retention. To understand patient experiences with intermittent catheterization, we interviewed 34 adults and parents of children affected by chronic urinary retention. RESULTS: We found 14 randomized controlled trials that met the inclusion criteria. When comparing any type of single-use or multiple-use IC, we found no difference in UTI (RR = 0.98, 95% CI 0.70-1.39), hematuria, or serious adverse events, and inconclusive evidence on patient satisfaction.Our meta-analysis of studies on people living in the community showed that hydrophilic ICs may result in fewer UTIs than single-use noncoated ICs, but given the nature of the studies, we were uncertain about this conclusion.The nature of the available evidence also did not allow us to make definitive conclusions regarding whether one type of catheter was likely to result in less hematuria, fewer serious adverse events, or greater patient satisfaction.Our economic evaluation found that owing to small differences in quality-adjusted life-years and moderate to large incremental cost differences, the lowest-cost ICs-noncoated multiple-use (using one catheter per week or one catheter per day)-have the highest probability of being cost-effective. In a subpopulation of those clinically advised not to reuse ICs, single-use noncoated ICs have the highest probability of being cost-effective. As current funding is limited in the outpatient setting, publicly funding noncoated multiple-use catheters (one per day) would result in a total additional cost of $93 million over the first 5 years. People who use ICs reported that the high ongoing cost of purchasing catheters was a financial burden. Almost all said they would prefer not to reuse catheters sold as "single use" but could not afford to do so. CONCLUSIONS: Given the overall low quality of evidence in available studies, we are uncertain whether any specific type of IC (coated or noncoated, single- or multiple-use) significantly reduces symptomatic UTI, hematuria, or other serious adverse clinical events, or whether a specific type improves patient satisfaction. Therefore, the lowest-cost IC is likely the most cost-effective.

Hospital-based Emergency Department Visits with Periapical Abscess: Updated Estimates from 7 Years.

INTRODUCTION: The impact of the Affordable Care Act (ACA) on the utilization of the emergency department (ED) for periapical abscess (PA) is unknown. The objectives of this study were to provide nationwide estimates of hospital-based ED visits with PA and to examine the effect of the ACA on the use of EDs for PAs. METHODS: We performed a retrospective analysis of the Nationwide Emergency Department Sample (NEDS) for 2008 to 2014. All ED visits with a diagnosis of PA were selected. The International Classification of Diseases, Ninth Revision-Clinical Modification code was used to identify PA. Patient- and hospital-level characteristics were examined. Descriptive statistics were used to summarize the data. RESULTS: From 2008 to 2014, a total of 3,505,633 ED visits for PA occurred. The proportion of ED visits with PA significantly increased over the study period (from 460,260 in 2008 to 545,693 in 2014). Medicaid was the primary payer (30.3%) and more than 40% were uninsured. Mean charge per PA-related ED visit was $1080.50 and total PA-related ED charge across the United States was $3.4 billion. Among those hospitalized following PA-related ED visits, mean hospitalization charges were $34,245 and total hospitalization charges were $5.7 billion. CONCLUSION: Oral health continues to be overlooked in health care. A large proportion of ED visits with PA were made by those covered by Medicaid and uninsured. The passing of the ACA has not reduced the number of ED visits with PA.

Economic analysis of prophylactic pegfilgrastim in adult cancer patients receiving chemotherapy.

OBJECTIVES: Neutropenia and its complications, including febrile neutropenia (FN), are a common side effect of cancer chemotherapy. Results of clinical trials showed that prophylactic use of granulocyte colony-stimulating factors (G-CSF) is effective in preventing FN. In this study, the cost effectiveness (measured as cost per quality-adjusted time [days]) of three treatment alternatives were evaluated: no G-CSF, filgrastim administered daily for 7-12 days after chemotherapy, and a pegylated form of G-CSF pegfilgrastim, administered once per cycle. METHODS: A cost-utility model based on standard clinical practice of treating FN with immediate hospitalization or with ambulatory treatment, from a societal perspective was developed. Direct medical cost estimates for hospitalization were derived from claims data reported by 115 US academic medical centers. Indirect medical costs, productivity costs, probabilities, and utilities are based on published literature. Results were subjected to sensitivity analyses and 95% confidence intervals are based on a Monte Carlo simulation. RESULTS: Mean estimated costs/day of hospitalization were $1984 (SD $1040, N = 24,687) for surviving patients and $3139 (SD $2014, N = 1437) for dying patients. Under baseline conditions, pegfilgrastim dominated both filgrastim and no G-CSF, with expected costs and effectiveness of $4203 and 12.361 quality adjusted life-days (QALDs) for no G-CSF, $3058 and 12.967 QALDs for pegfilgrastim, and $5264 and 12.698 QALDs for filgrastim. CONCLUSIONS: This cost-utility analysis provides strong evidence that pegfilgrastim is not only cost-effective but also cost-saving in most common clinical and economic settings. There appear to be both clinical and economic benefits from prophylactic administration of pegfilgrastim.
