RESUMO

PURPOSE: The effects of chemotherapy dose intensity on survival in patients with advanced non-small-cell lung cancer (NSCLC) are poorly understood. We retrospectively analyzed dose delays/reduction, relative dose intensity (RDI), and the association between chemotherapy intensity and survival in advanced NSCLC. METHODS: This retrospective cohort study included adults with advanced lung cancer who received first-line myelosuppressive platinum-based chemotherapy (January 2007-December 2010) in ~ 230 US Oncology Network community practices. Dose delays ≥ 7 days, dose reductions ≥ 15%, and RDI relative to standard regimens were described. Overall survival (OS) was measured using Kaplan-Meier and Cox proportional hazard (PH) models. RESULTS: Among 3866 patients with advanced NSCLC, 32.4% experienced dose delays ≥ 7 days, 50.1% experienced dose reductions ≥ 15%, and 40.4% had RDI < 85%. Reduced RDI was also common regardless of baseline ECOG PS (ECOG PS ≥ 2, 56.2%; ECOG PS 0, 33.6%) and tumor subgroup (squamous cell carcinoma, 52.2%; adenocarcinoma, 36.0%). When stratified by chemotherapy intensity measures, significant OS differences were observed only for dose delays. Median (95% CI) OS was 1.02 years (0.96-1.12) for dose delays ≥ 7 days and 0.71 years (0.66-0.77) for dose delays < 7 days. In multivariable Cox PH analysis, dose delays ≥ 7 days (HR = 0.71; 95% CI = 0.63-0.80) and RDI ≥ 85% (HR = 1.18; 95% CI = 1.05-1.32) were significantly associated with decreased mortality. CONCLUSIONS: Dose delays, dose reductions, and reduced RDI were common, and dose delays ≥ 7 days and high RDI were significantly associated with decreased mortality. These results can help identify potential risk factors and characterize the effect of chemotherapy dose modification strategies on mortality.

RESUMO

PURPOSE: The study objective was to evaluate chemotherapy treatment patterns and incidence, cost, and resource utilization of febrile neutropenia-related hospitalization (FNH) in patients with breast cancer, lung cancer, and non-Hodgkin's lymphoma (NHL) from Kaiser Permanente Southern California (KPSC), a large integrated delivery system. METHODS: Adults ≥18 years with any stage breast cancer, lung cancer, or NHL who initiated myelosuppressive chemotherapy from 01/01/2006 to 12/31/2009 were included. Chemotherapy dose delays ≥7 days, relative dose intensity (RDI), regimen switching, FNH and all-cause mortality, granulocyte colony-stimulating factor (G-CSF) and antibiotic use, and healthcare utilization/cost were evaluated by cancer type, regimen, and/or cycle. RESULTS: Among 3314 breast cancer patients, 25.3% received an RDI ≤85%, 13.9% experienced FNH with an all-cause mortality rate of 2.0%, and 20.2% received primary prophylaxis with G-CSF. Among those with FNH, mean hospital length of stay (LOS) was 4.1 days, and mean total costs were $20,462. Among 1443 lung cancer patients, 17.9% had an RDI ≤85%, 8.0% experienced FNH with an all-cause mortality rate of 25.2%, and 4.5% received primary prophylaxis with G-CSF. Among those with FNH, mean LOS was 6.8 days, and mean total costs were $32,964. Among 581 NHL patients, 27.9% had an RDI ≤85% and 22.4% experienced FNH with an all-cause mortality rate of 13%. Among those with FNH, mean LOS was 7.9 days, and mean total costs were $37,555. CONCLUSIONS: Marked variability was observed among different cancer types and chemotherapy regimens. Given the variability, detailed insight into incidence, management, and burden of FN can help inform clinical decision making.

RESUMO

Patients receiving myelosuppressive chemotherapy with certain comorbidities are at increased risk of febrile neutropenia. A comprehensive evaluation of febrile neutropenia-related comorbidities across cancers is needed. This study compared comorbidity prevalence among patients with cancer who did and did not develop febrile neutropenia during the first chemotherapy cycle. This case-control study used administrative claims from adult patients with non-Hodgkin lymphoma or breast, lung, colorectal, ovarian, or gastric cancer who received chemotherapy between 2007 and 2012. Each patient who developed febrile neutropenia (case) was matched with up to four patients without febrile neutropenia (controls) by cancer type, metastasis, chemotherapy regimen, age group, and sex. For each comorbidity (identified in the year before chemotherapy began), the adjusted odds ratio (aOR) for febrile neutropenia by cancer type was evaluated using conditional logistic regression models adjusted for potential confounding factors. Of 31,331 eligible patients, 672 developed febrile neutropenia in the first chemotherapy cycle. A total of 3312 febrile neutropenia cases and matched controls were analyzed. Across tumor types, comorbidity prevalence was higher in patients who developed febrile neutropenia than in those without febrile neutropenia. Among patients with breast cancer, osteoarthritis was more prevalent in patients with febrile neutropenia (aOR, 1.85; 95% CI, 1.07 to 3.18). Among patients with non-Hodgkin lymphoma, renal disease was more prevalent in patients with febrile neutropenia (aOR, 2.25; 95% CI, 1.23 to 4.11). Patients who developed febrile neutropenia in the first chemotherapy cycle presented with comorbidities more often than otherwise similar patients who did not develop febrile neutropenia. These findings warrant further investigation and support the inclusion of comorbidities into febrile neutropenia risk models.

RESUMO

BACKGROUND: A wide variety of myelosuppressive chemotherapy regimens are used for the treatment of cancer in clinical practice. Neutropenic complications, such as febrile neutropenia, are among the most common side effects of chemotherapy, and they often necessitate delays or reductions in doses of myelosuppressive agents. Reduced relative dose intensity (RDI) may lead to poorer disease-free and overall survival. METHODS: Using the McKesson Specialty Health/US Oncology iKnowMed electronic health record database, we retrospectively identified the first course of adjuvant or neoadjuvant chemotherapy received by patients without metastases who initiated treatment between January 1, 2007, and March 31, 2011. For each regimen, we estimated the incidences of dose delays (≥7 days in any cycle of the course), dose reductions (≥ 15% in any cycle of the course), and reduced RDI (<85% over the course) relative to the corresponding standard tumor regimens described in the NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines). RESULTS: This study included 16,233 patients with 6 different tumor types who received 1 of 20 chemotherapy regimens. Chemotherapy dose delays, dose reductions, and reduced RDI were common among patients treated in community oncology practices in the United States, but RDI was highly variable across patients, regimens, and tumor types (0.486-0.935 for standard tumor regimen cohorts). Reduced RDI was more common in older patients, obese patients, and patients whose daily activities were restricted. CONCLUSIONS: In this large evaluation of RDI in US clinical practice, physicians frequently administered myelosuppressive agents at dose intensities lower than those of standard regimens.

RESUMO

PURPOSE: The study aims to assess the relative efficacy of granulocyte colony-stimulating factor (G-CSF) products administered as primary prophylaxis (PP) to patients with cancer receiving myelosuppressive chemotherapy. METHODS: A systematic literature review identified publications (January 1990 to September 2013) of randomized controlled trials evaluating PP with filgrastim, pegfilgrastim, lenograstim, or lipegfilgrastim in adults receiving myelosuppressive chemotherapy for solid tumors or non-Hodgkin lymphoma. Direct, indirect, and mixed-treatment comparison (MTC) were used to estimate the odds ratio and 95 % credible interval of febrile neutropenia (FN) during cycle 1 and all cycles of chemotherapy combined without adjusting for differences in relative dose intensity (RDI) between study treatment arms. RESULTS: Twenty-seven publications representing 30 randomized controlled trials were included. Using MTC over all chemotherapy cycles, PP with filgrastim, pegfilgrastim, lenograstim, and lipegfilgrastim versus no G-CSF PP or placebo were associated with statistically significantly reduced FN risk. FN risk was also significantly reduced with pegfilgrastim PP versus filgrastim PP. Over all chemotherapy cycles, there was a numerical but statistically nonsignificant increase in the FN risk for lipegfilgrastim PP versus pegfilgrastim PP. Using MTC in cycle 1, PP with filgrastim, pegfilgrastim, and lipegfilgrastim versus no G-CSF PP or placebo were associated with statistically significantly reduced FN risk. CONCLUSIONS: In this meta-analysis, using MTC without adjustment for RDI, PP with all G-CSFs evaluated reduced the FN risk in patients receiving myelosuppressive chemotherapy. Future studies are needed to assess the influence of RDI on FN outcomes and to eliminate potential bias between G-CSF arms receiving more intensive chemotherapy than control arms.

RESUMO

OBJECTIVE: Evaluate the cost-effectiveness of primary prophylaxis (PP) or secondary prophylaxis (SP) with pegfilgrastim, filgrastim (6-day and 11-day), or no prophylaxis to reduce the risk of febrile neutropenia (FN) in patients with recurrent ovarian cancer receiving docetaxel or topotecan. METHODS: A Markov model was used to evaluate the cost-effectiveness of PP vs SP from a US payer perspective. Model inputs, including the efficacy of each strategy (relative risk of FN with prophylaxis compared to no prophylaxis) and mortality, costs, and utility values were estimated from public sources and peer-reviewed publications. Incremental cost-effectiveness was evaluated in terms of net cost per FN event avoided, incremental cost per life-year saved (LYS), and incremental cost per quality-adjusted life-year (QALY) gained over a lifetime horizon. Deterministic and probabilistic sensitivity analyses (DSA and PSA) were conducted. RESULTS: For patients receiving docetaxel, the incremental cost-effectiveness ratio (ICER) for PP vs SP with pegfilgrastim was $7900 per QALY gained, and PP with pegfilgrastim dominated all other comparators. For patients receiving topotecan, PP with pegfilgrastim dominated all comparators. Model results were most sensitive to baseline FN risk. PP vs SP with pegfilgrastim was cost effective in 68% and 83% of simulations for docetaxel and in >99% of simulations for topotecan at willingness-to-pay thresholds of $50,000 and $100,000 per QALY. CONCLUSIONS: PP with pegfilgrastim should be considered cost effective compared to other prophylaxis strategies in patients with recurrent ovarian cancer receiving docetaxel or topotecan with a high risk of FN.

RESUMO

BACKGROUND: The Veterans Health Administration (VHA) is the largest integrated health care system in the United States and a major cancer care provider. OBJECTIVE: To use VHA database to conduct a population-based study of patterns of myelosuppressive chemotherapy use and to assess the incidence and management of febrile neutropenia (FN) among VHA patients with lung, colorectal, or prostate cancer or non-Hodgkin lymphoma (NHL). METHODS: Data were extracted for the initial myelosuppressive chemotherapy course for 27,899 patients who began treatment in the period 2006 to 2011. FN-related costs were defined as claims containing FN diagnosis. RESULTS: Most patients were men (98.0%); most were 65 years or older (55.8%). Patients received a mean 3.4 to 3.9 chemotherapy cycles/course (median cycle duration 34-43 days). The incidence of FN among patients with lung, colorectal, or prostate cancer or NHL was 10.2%, 4.6%, 5.4%, and 17.3%, respectively. Primary or secondary prophylactic antibiotics/colony-stimulating factors were received by 21% and 12% of patients, respectively. Antibiotics were more commonly given as primary or secondary prophylaxis for patients with lung, colorectal, and prostate cancer; colony-stimulating factors were more common for patients with NHL. Among patients with FN, those with lung cancer had the highest inpatient mortality (10%); patients with NHL had the highest costs ($24,571) and the longest hospital length of stay (15.4 days). CONCLUSIONS: VHA cancer care was generally consistent with National Comprehensive Cancer Network recommendations; however, compared with the general population, chemotherapy cycles were longer, combination chemotherapy was used less, and treatment to prevent FN was used less, differences that may be attributed to the unique VHA patient population. The impact of these practices warrants further investigation.

RESUMO

OBJECTIVES: Rising out-of-pocket costs for cancer patients have increased shared decision making. Clinical guidelines recommend prophylactic granulocyte colony-stimulating factor (G-CSF) for patients receiving chemotherapy with a 20% or greater risk of febrile neutropenia. A discrete choice experiment was conducted to explore breast cancer patients' preferences and willingness to pay (WTP) for prophylactic G-CSF to decrease the risk of chemotherapy-induced febrile neutropenia. METHODS: An online discrete choice experiment questionnaire survey of a national US convenience sample of self-reported breast cancer patients with prior chemotherapy treatment was conducted. Sixteen paired G-CSF treatment scenarios, each with four attributes (risk of disruption to chemotherapy schedule due to low white blood cell counts, risk of developing an infection requiring hospitalization, frequency of administration, and total out-of-pocket cost) were presented with a follow-up "no treatment" option. Participant preferences and WTP out of pocket were estimated by logistic regression. RESULTS: Participants (n = 296) preferred G-CSF regimens with lower out-of-pocket costs, lower risk of chemotherapy disruption, lower risk of infection, and greater convenience (one G-CSF injection per chemotherapy cycle). Participants' WTP was $1076 out of pocket per cycle to reduce the risk (high to low) of disrupting their chemotherapy schedule, $884 per cycle to reduce the risk (24% [high] to 7% [low]) of infection, and $851 per cycle to decrease the number of G-CSF injections (11 to 1) per cycle. CONCLUSIONS: Participants highly valued specific features of prophylactic G-CSF treatment including maintaining their chemotherapy schedule, lowering their risk of infection, and reducing the number of injections. Physicians should consider patient preferences to inform the best treatment choices for individual patients.

RESUMO

PURPOSE: Febrile neutropenia (FN) is a common and serious complication of myelosuppressive chemotherapy. Guidelines recommend primary granulocyte colony-stimulating factors (G-CSF) prophylaxis (PPG) in patients with a high risk (HR, >20 %) of developing FN. We performed a retrospective analysis using a subset of the Medicare 5 % database to assess patterns of G-CSF use and FN occurrence among elderly cancer patients receiving myelosuppressive chemotherapy. METHODS: Chemotherapy courses for patients aged 65+ years were identified; only the first course was used for this analysis. Using clinical guidelines, chemotherapy regimens were classified as HR or intermediate risk (IR) for FN. The first administration of G-CSF was classified as either PPG (within the first 5 days of the first cycle), secondary prophylaxis, or reactive. RESULTS: Twelve thousand seven hundred seven courses across five tumor types were classified as having a HR or IR regimen. G-CSF was used in 24.5-73.8 % of patients receiving a HR FN regimen, with the highest use in breast cancer or NHL. Except for breast cancer (where PPG was used in 52.1 %), PPG was given in less than half of patients receiving a HR regimen. Depending on the tumor type, 4.8-22.6 % of patients with a HR regimen had a neutropenia-related hospitalization. CONCLUSIONS: Guidelines recommend PPG with HR FN regimens and older age (>65 years), an important risk factor for developing severe neutropenic complications. However, our results show that in this elderly population, PPG was not routinely used (range 4.8-52.1 %) in patients receiving HR FN regimens. Careful attention to FN risk factors, including chemotherapy regimen and patient age, is needed when planning treatment strategies.

RESUMO

OBJECTIVE: To examine the incidence, treatment, and consequences of febrile neutropenia across inpatient and outpatient care settings. METHODS: Data were obtained from Humedica's National Electronic Health Record-Derived Longitudinal Patient-Level Database (2007-2010). The study population included adult patients who received myelosuppressive chemotherapy for a solid tumor or non-Hodgkin's lymphoma. For each patient, each chemotherapy regimen course and each cycle within each regimen course was characterized. Febrile neutropenia episodes were identified on a cycle-specific basis based on any of the following: (1) absolute neutrophil count <1.0 × 10(9)/L and evidence of infection or fever; (2) inpatient diagnosis of neutropenia, fever, or infection; (3) outpatient diagnosis of neutropenia and non-prophylactic antimicrobial use; or (4) mention of febrile neutropenia in physician notes. Febrile neutropenia episodes were categorized as inpatient or outpatient based on the initial setting of care (i.e. acute-care inpatient facility vs. ambulatory care facility). Febrile neutropenia consequences included hospital length of stay and mortality (inpatient cases only), as well as number of febrile neutropenia-related outpatient encounters. RESULTS: Among the 2131 patients in this study, 401 experienced a total of 458 febrile neutropenia episodes. Risk of febrile neutropenia during the chemotherapy regimen course was 16.8% (95% CI: 15.3, 18.4). In cycle 1 alone, risk of febrile neutropenia was 8.1% (7.1, 9.3). Most febrile neutropenia episodes (83.2%) were initially treated in the inpatient setting; the hospital mortality rate was 8.1% (5.8, 11.1), and mean hospital length of stay was 8.4 days (7.7, 9.1). Among febrile neutropenia episodes initially treated in the outpatient setting (16.8%), the mean number of outpatient management encounters was 2.6 (2.1, 3.1), most of which were in the physician's office (69.2%) or emergency department (26.9%). CONCLUSIONS: Febrile neutropenia remains a common occurrence among patients receiving myelosuppressive chemotherapy and typically results in extended hospitalization and, for many patients, death. A minority of patients are, however, treated exclusively on an outpatient basis.

RESUMO

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.

RESUMO

Advancing age, female sex, recent prior fracture and falls, and specific comorbidities and medications contribute to imminent (within 1-2 years) risk of fracture in Medicare enrollees. Clinician awareness of these risk factors and their dynamic nature may lead to improved osteoporosis care for elderly patients. PURPOSE: The burden of osteoporotic fracture disproportionately affects the elderly. Growing awareness that fracture risk can change substantially over time underscores the need to understand risk factors for imminent (within 1-2 years) fracture. This study assessed predictors of imminent risk of fracture in the US Medicare population. METHODS: Administrative claims data from a random sample of Medicare beneficiaries were analyzed for patients aged ≥ 67 years on January 1, 2011 (index date), with continuous coverage between January 1, 2009 and March 31, 2011, excluding patients with non-melanoma cancer or Paget's disease. Incident osteoporotic fractures were identified during 12 and 24 months post-index. Potential predictors were age, sex, race, history of fracture, history of falls, presence of osteoporosis, cardiovascular diseases, chronic obstructive pulmonary disorder (COPD), mood/anxiety disorders, polyinflammatory conditions, difficulty walking, use of durable medical equipment, ambulance/life support, and pre-index use of osteoporosis medications, steroids, or central nervous system medications. Cox proportional hazards models were used to evaluate predictors of fracture risk in the two follow-up intervals. RESULTS: Among 1,780,451 individuals included (mean age 77.7 years, 66% female), 8.3% had prior fracture and 6.1% had a history of falls. During the 12- and 24-month follow-up periods, 3.0% and 5.4% of patients had an incident osteoporotic fracture, respectively. Imminent risk of fracture increased with older age (double/triple), female sex (> 80%), recent prior fracture (> double) and falls, and specific comorbidities and medications.

RESUMO

OBJECTIVES: To develop and validate predictive models for imminent fracture risk in a Medicare population. STUDY DESIGN: This retrospective administrative claims (Humana Research Database) study assessed imminent risk in Humana's Medicare Advantage and Prescription Drug plan members. METHODS: Individuals (aged 67-87 years on January 1, 2015 [index]) with 1 year or more of history were followed for 3 months to up to 2 years, with censoring at death/disenrollment. The cohort was split into training and validation samples (1:1). Cox regression models assessed demographics, fracture history, medically significant falls, osteoporosis-related factors, frailty markers, and selected medications and comorbidities for independent predictors (P <.001) of incident nontraumatic clinical fractures in 12 and 24 months. A 6-variable model of 12-month risk used a published method for the risk-scoring point system. RESULTS: Of 1,287,354 individuals (mean age, 74.3 years; 56% female; 84% white), 3.8% had at least 1 fragility fracture at 12-month follow-up; 6.6% experienced fracture at 24 months (women vs men: 12 months, 4.8% vs 2.5%; 24 months, 8.3% vs 4.4%; both P <.01). At 12 months, recent fracture conferred approximately 3-fold-higher fracture risk (vs no recent fracture). Older age, white race, female sex, osteoporosis-related screening/diagnosis/medication, antidepressant/antipsychotic/sedative hypnotic/muscle relaxant medications, history of falls, fracture history, and respiratory conditions also increased risk (all P <.0001). The simplified model (recent fracture, age, sex, race, falls, antidepressant/antipsychotic/sedative hypnotic/muscle relaxant medications) performed well (C statistic = 0.71). CONCLUSIONS: Recent fracture, older age, female sex, white race, falls, and antidepressant/antipsychotic/sedative hypnotic/muscle relaxant medications predict imminent fracture risk in an older-adult Medicare Advantage population. Imminent fracture risk can be assessed using 6 easily quantified factors.

RESUMO

PURPOSE: We investigated adherence to benign prostatic hyperplasia medications in a California Medicaid population. MATERIALS AND METHODS: Using California Medicaid data on 1995 to 2004 we identified adult males 40 years old or older with 1 or more diagnosis and 2 or more prescription fills for benign prostatic hyperplasia. Patients with 2 fills on the same day were assigned to the multiple medication cohort. Adherence was measured using the medication possession ratio for the index medication and the proportion of days covered for any benign prostatic hyperplasia medication. Patients with a medication possession ratio or proportion of days covered of 0.8 or greater were considered adherent. A Cox proportional hazards model was used to assess the relative hazards associated with discontinuation. Multiple logistic regression was used to investigate factors associated with nonadherence or a benign prostatic hyperplasia related procedure. RESULTS: Of the total population of 2,640 men 40% were adherent with any benign prostatic hyperplasia medication. A significantly greater proportion of patients using multiple medications and finasteride were adherent with any benign prostatic hyperplasia medication (62% and 55%, respectively, p <0.0001). Doxazosin, terazosin and tamsulosin use was associated with nonadherence (p = 0.008, 0.04 and 0.03, respectively). Younger patients and those changing medications were more likely to discontinue (p = 0.01 and <0.0001), while patients using multiple medications and those experiencing a gap were at lower risk for discontinuation (p = 0.01 and <0.0001, respectively). Predictors of a procedure included an index prescription in 1999 or later, a urologist visit and nonadherence to any benign prostatic hyperplasia medication (p = 0.01, <0.0001 and <0.0001, respectively). CONCLUSIONS: Adherence to alpha-blockers was less than adherence to finasteride or multiple medications and nonadherence was significantly associated with a procedure. Interventions focused on improving adherence to benign prostatic hyperplasia medications are clearly needed.

RESUMO

BACKGROUND: Prophylaxis with granulocyte colony-stimulating factor reduces the risk for febrile neutropenia (FN) in patients receiving myelosuppressive chemotherapy. OBJECTIVE: We estimated the incremental cost-effectiveness of primary prophylaxis (starting in cycle 1 of chemotherapy) with pegfilgrastim versus filgrastim in women with early-stage breast cancer receiving myelosuppressive chemotherapy in the United States. METHODS: A decision-analytic model was constructed from a health payer's perspective with a lifetime study horizon. The model considered direct medical costs and outcomes related to reduced FN and potential survival benefits due to reduced FN-related mortality and on-time receipt of full-dose chemotherapy. Sensitivity analyses were conducted. RESULTS: Pegfilgrastim was cost-saving and more effective (ie, dominant strategy) than 11-day filgrastim. The incremental cost-effectiveness ratio (ICER) for pegfilgrastim versus 6-day filgrastim was $12,904 per FN episode avoided. Adding the survival benefit due to reduced FN mortality and receipt of optimal chemotherapy dose yielded an ICER of $31,511 per quality-adjusted life year (QALY) gained and $14,415 per QALY gained, respectively. The most influential factors included inpatient FN case-fatality rate, cost of pegfilgrastim and filgrastim, baseline probability of FN, relative risk for FN between filgrastim and pegfil-grastim, and cost of administration of filgrastim. CONCLUSION: Pegfilgrastim was cost-saving compared with 11-day filgrastim and cost-effective compared with 6-day filgrastim from a health payer's perspective for the primary prophylaxis of FN in these women with early-stage breast cancer receiving myelosuppressive chemotherapy.

RESUMO

OBJECTIVES: The study examined the impact of chemotherapy-induced neutropenic complications (CINC), defined as neutropenia with fever or infection, on short-term disability (STD) among cancer patients receiving chemotherapy. METHODS: The key outcome metrics were average monthly STD days and associated indirect costs. Patients with and without CINC were propensity score (PS) matched. Multivariate regressions were conducted on PS-matched cohorts to estimate the marginal impact of CINC. RESULTS: A total of 280 patients with CINC were PS-matched to 280 patients without CINC. Compared with matched patients, patients with CINC on average experienced 0.9 more STD day (3.2 vs. 2.3, p=0.046) and $155 more in indirect costs ($549 vs. 394, p=0.050) per month. After multivariate adjustment, patients with CINC experienced 1.0 more STD day (p=0.029), and incurred $200 more in indirect cost (p=0.016) per month. CONCLUSIONS: Patients with CINC experience significantly greater STD leave than patients with no neutropenic complications from cancer chemotherapy. The overall study sample only included patients from large self-insured employers in the US and may not reflect the work loss experience of all employed patients in the US or other countries. Indirect costs associated with absenteeism and presenteeism were not measured.

RESUMO

Osteoporosis treatment decisions are often based solely on BMD or on 10-year fracture risk; little is known about factors increasing imminent fracture risk. Understanding factors contributing to imminent risk of fracture is potentially useful for personalizing therapy, especially among those at high risk. Our aim was to identify predictors of nonvertebral fracture for 1- and 2-year periods in women at high risk for fracture. The Framingham Osteoporosis Study cohort included 1470 women (contributing 2778 observations), aged ≥65 years with BMD hip T-score ≤ -1.0, or history of fragility fracture (irrespective of T-score). Nonvertebral fractures were ascertained prospectively over 1 year and 2 years following a baseline BMD scan. Potential risk factors included age, anthropometric variables, comorbidities/medical history, cognitive function, medications, history of fracture, self-rated health, falls in the past year, smoking, physical performance, hip BMD T-score, Activities of Daily Living (ADL) score, and caffeine and alcohol intakes. Predictive factors with p value ≤ 0.10 in bivariate Cox proportional hazards regression models were subsequently considered in multivariable models. Mean baseline age was 75 years (SD 6.0). During 1-year follow-up, 89 nonvertebral fractures occurred; during 2-year follow-up, 176 fractures occurred. Of the variables considered in the bivariate models, significant predictors of nonvertebral fractures included age, history of fracture, self-rated health, falls in the prior year, BMD T-score, ADL, renal disease, dementia, and current use of nitrates, beta-blockers, calcium channel blockers, or antidepressants. In multivariable models, significant independent risk factors were history of fracture, self-rated health, hip BMD T-score, and use of nitrates. Significant 1-year results were attenuated at the 2-year follow-up. In addition to the traditional factors of BMD and fracture history, self-rated health and use of nitrates were independently associated with imminent risk of fracture in older, high-risk women. These specific risk factors thus may be useful in identifying which women to target for therapy.

RESUMO

OBJECTIVE: To assess the safety and evaluate the effects of repeated treatments with botulinum toxin type A (BTX-A) on functional disability, quality of life (QOL), and muscle tone of patients with upper-limb poststroke spasticity, as well as its effect on caregivers. DESIGN: Multicenter, open-label, repeated-dose study. SETTING: Thirty-five clinical sites in North America. PARTICIPANTS: Patients (N=279) with upper-limb poststroke spasticity at 6 months or more poststroke. INTERVENTION: Up to 5 intramuscular injections of BTX-A (200-400U) divided among the wrist, finger, thumb, and elbow flexors, with at least 200U in the wrist and finger flexors. Retreatment was permitted at 12 weeks or more after the last treatment. MAIN OUTCOME MEASURES: Investigators rated disability using the Disability Assessment Scale and muscle tone using the Ashworth Scale. Each patient's health-related QOL was assessed by using the Stroke Adapted Sickness Impact Profile and the visual analog scale of the European Quality of Life-5 Dimensions questionnaires. RESULTS: Patients treated with BTX-A reported improvements in muscle tone, disability, and ability to function that were statistically significant and clinically meaningful. Significant improvements were observed at week 30 and at subsequent time points in QOL in the overall group and the high-dose group. CONCLUSIONS: Up to 5 treatments with BTX-A every 12 weeks for up to 56 weeks in patients with poststroke spasticity was well tolerated and significantly improved muscle tone, lessened disability, and improved patients' QOL. Further research is required to examine the effectiveness of repeated injections of BTX-A in patients with poststroke spasticity.

RESUMO

OBJECTIVES: To estimate the incremental direct medical care costs associated with first fracture observable in high-risk older adults. DESIGN: Retrospective analysis of claims and survey data over a 3-year period from the Health and Retirement Study (HRS), a nationally representative biennial study of individuals aged 50 and older. SETTING: United States. PARTICIPANTS: Participants were HRS respondents who consented to have their Medicare claims data linked to the HRS data, were aged 65 or older, had at least 1 risk factor for fracture observable in the data, and experienced a fracture between 1996 and 2008 (n = 689) and their propensity score-matched controls (n = 689). MEASUREMENTS: Total Medicare, inpatient, outpatient, emergency department, physician office visit, and prescription drug care expenditures were primary outcomes. Two-staged generalized linear models were estimated using a difference-in-differences model. RESULTS: Fracture cases' total Medicare expenditures increased by $13,929 (95% confidence interval (CI)=$11,920-15,938, p <.001) more than those of matched controls from the year before the index or fracture date to 1 year after the index date. Inpatient expenditures of $12,751 (95% CI=$10,790-14,7111, p < .001) more for fracture cases than comparison cases primarily drove this increase. Two and 3 years after fracture, there were no significant differences in growth in expenditures between the two groups. Results did not vary according to whether the fracture was at the hip or other site. CONCLUSION: Fractures impose a significant economic burden, especially in the first year after the fracture, in Medicare beneficiaries with at least 1 risk factor for fracture. Our sample was limited to community-dwelling individuals, and we are unable to control for fracture history before the study period. Costs may be greater for those in skilled nursing and similar facilities and for those who have had a previous fracture. J Am Geriatr Soc 66:2298-2304, 2018.
