RESUMO

Importance: Bone health screening is recommended for patients with prostate cancer who are initiating treatment with androgen deprivation therapy (ADT); however, bone mineral density screening rates in the US and their association with fracture prevention are unknown. Objective: To assess dual-energy x-ray absorptiometry (DXA) screening rates and their association with fracture rates among older men with prostate cancer initiating treatment with androgen deprivation therapy. Design, Setting, and Participants: This retrospective nationwide population-based cohort study used data from the Surveillance, Epidemiology, and End Results database and the Texas Cancer Registry linked with Medicare claims. Participants comprised 54 953 men 66 years or older with prostate cancer diagnosed between January 2005 and December 2015 who initiated treatment with ADT. Data were censored at last enrollment in Medicare and analyzed from January 1 to September 30, 2021. Exposures: Dual-energy x-ray absorptiometry screening within 12 months before and 6 months after the first ADT claim. Main Outcomes and Measures: Frequencies of DXA screening and fracture (any fracture and major osteoporotic fracture) and overall survival were calculated. The association between DXA screening and fracture was evaluated using a multivariable Cox proportional hazards model with propensity score adjustment. Results: Among 54 953 men (median age, 74 years; range, 66-99 years) with prostate cancer, 4689 (8.5%) were Hispanic, 6075 (11.1%) were non-Hispanic Black, 41 453 (75.4%) were non-Hispanic White, and 2736 (5.0%) were of other races and/or ethnicities (including 121 [0.2%] who were American Indian or Alaska Native; 1347 [2.5%] who were Asian, Hawaiian, or Pacific Islander; and 1268 [2.3%] who were of unknown race/ethnicity). Only 4362 men (7.9%) received DXA screening. The DXA screening rate increased from 6.8% in 2005 to 8.4% in 2015. Lower screening rates were associated with being single (odds ratio [OR], 0.89; 95% CI, 0.81-0.97; P = .01) and non-Hispanic Black (OR, 0.80; 95% CI, 0.70-0.91; P < .001), living in small urban areas (OR, 0.77; 95% CI, 0.66-0.90; P = .001) and areas with lower educational levels (OR, 0.75; 95% CI, 0.67-0.83; P < .001), and receiving nonsteroidal androgens (OR, 0.57; 95% CI, 0.39-0.84; P = .004). Overall, 9365 patients (17.5%) developed fractures after initial receipt of ADT. The median time to first fracture was 31 months (IQR, 15-56 months). In the multivariable model with propensity score adjustment, DXA screening was not associated with fracture risk at any site (hazard ratio [HR], 0.96; 95% CI, 0.89-1.04; P = .32) among men without previous fractures before receipt of ADT. However, previous DXA screening was associated with a decreased risk of major fractures (HR, 0.91; 95% CI, 0.83-1.00; P = .05) after propensity score adjustment. Conclusions and Relevance: In this study, low DXA screening rates were observed among older men with localized or regional prostate cancer after initiation of treatment with ADT. Despite low rates of screening, evaluation of bone mineral density with a DXA scan was associated with lower risk of major fractures. These findings suggest that DXA screening is important for the prevention of major fractures among older men with prostate cancer and that implementation strategies are needed to adopt bone health screening guidelines in clinical practice.

RESUMO

PURPOSE: Although rates of hospice use have increased over time, insurance plan- and racial/ethnic-based disparities in rates have been reported in the USA. We hypothesized that increased rates of hospice use would reduce or eliminate insurance plan-based disparities and that racial/ethnic disparities would be eliminated in managed care (MC) insurance plans. METHODS: We studied the use of hospice care in the final 30 days of life among 40,184 elderly Texas Medicare beneficiaries who died from primary breast, colorectal, lung, pancreas, or prostate cancer between January 1, 2007 and December 31, 2013, using statewide Medicare claims linked to cancer registry data. Rates of hospice use were computed by race/ethnicity and insurance plan (MC or fee-for-service (FFS)). We used logistic regression to account for the impact of confounding factors. RESULTS: Rates of hospice use increased significantly over time, from 68.9% in 2007 to 76.1% in 2013. By 2013, differences in hospice use rates between MC and FFS plans had been reduced from 10% to < 5%. However, after accounting for insurance plan and confounding factors, racial/ethnic minority beneficiaries' hospice use was significantly lower than non-Hispanic white beneficiaries' (p < 0.0001). This disparity was observed among both FFS and MC beneficiaries. CONCLUSIONS: Hospice use in the final 30 days of life has increased among elderly cancer patients in Texas, virtually eliminating the difference between FFS and MC insurance plans. Despite these positive trends, racial/ethnic-based disparities persist. These disparities are not explained by confounding factors. Future research should address social and behavioral influences on end-of-life decisions.

RESUMO

Oral complications of cancer treatment are common; however, their clinical and economic importance is often underappreciated. We reviewed the literature on the economic implications of oral complications, updating a previous report in the predecessor to this issue. We searched the Medline and Scopus databases for papers published as of December 31, 2017 that described the economic consequences of preventing and managing oral complications and reviewed the literature reporting the costs of oral mucositis, xerostomia, and osteonecrosis. Cost estimates were inflated to 2017 US dollars. We identified 16 papers describing the cost of managing mucositis, eight describing the cost of osteoradionecrosis, one describing the cost of bisphosphonate-associate osteonecrosis of the jaw, and four describing the cost of xerostomia. The incremental cost of oral mucositis was approximately $5000-$30 000 among patients receiving radiation therapy and $3700 per cycle among patients receiving chemotherapy. The incremental cost of mucositis-related hospitalization among stem cell transplant recipients exceeded $70 000. Conservative management of osteoradionecrosis (antibiotics, debridement) costs $4000-$35 000, although estimates as high as $74 000 have been reported. Hyperbaric oxygen therapy may add $10 000-$50 000 to the cost of therapy. Sialogogues are required for years for the management of xerostomia at a cost of $40-$200 per month. Serious (hospitalization, hyperbaric oxygen therapy) or long-term (sialogogues) outcomes are the major drivers of cost. Future research should address patients' out-of-pocket costs and the costs of oral complications of new treatments. Multisite studies, particularly those conducted by cooperative groups, should be prioritized.

RESUMO

OBJECTIVE Health disparities in access to care, early detection, and survival exist among adult patients with cancer. However, there have been few reports assessing how health disparities impact pediatric patients with malignancies. The objective in this study was to examine the impact of racial/ethnic and social factors on disease presentation and outcome for children with primary CNS solid tumors. METHODS The authors examined all children (age ≤ 18 years) in whom CNS solid tumors were diagnosed and who were enrolled in the Texas Cancer Registry between 1995 and 2009 (n = 2421). Geocoded information was used to calculate the driving distance between a patient's home and the nearest pediatric cancer treatment center. Socioeconomic status (SES) was determined using the Agency for Healthcare Research and Quality formula and 2007-2011 US Census block group data. Logistic regression was used to determine factors associated with advanced-stage disease. Survival probability and hazard ratios were calculated using life table methods and Cox regression. RESULTS Children with advanced-stage CNS solid tumors were more likely to be < 1 year old, Hispanic, and in the lowest SES quartile (all p < 0.05). The adjusted odds ratios of presenting with advanced-stage disease were higher in children < 1 year old compared with children > 10 years old (OR 1.71, 95% CI 1.06-2.75), and in Hispanic patients compared with non-Hispanic white patients (OR 1.56, 95% CI 1.19-2.04). Distance to treatment and SES did not impact disease stage at presentation in the adjusted analysis. Furthermore, 1- and 5-year survival probability were worst in children 1-10 years old, Hispanic patients, non-Hispanic black patients, and those in the lowest SES quartile (p < 0.05). In the adjusted survival model, only advanced disease and malignant behavior were predictive of mortality. CONCLUSIONS Racial/ethnic disparities are associated with advanced-stage disease presentation for children with CNS solid tumors. Disease stage at presentation and tumor behavior are the most important predictors of survival.

RESUMO

OBJECTIVE: To identify health disparities in pediatric patients with melanoma that affect disease presentation and outcome. STUDY DESIGN: This was a retrospective cohort study of all persons aged ≤18 years diagnosed with melanoma and enrolled in the Texas Cancer Registry between 1995 and 2009. Socioeconomic status (SES) and driving distance to the nearest pediatric cancer treatment center were calculated for each patient. Logistic regression was used to determine factors associated with advanced-stage disease. Life table methods and Cox regression were used to estimate survival probability and hazard ratios. RESULTS: A total of 185 adolescents (age >10 years) and 50 young children (age ≤10 years) were identified. Hispanics (n = 27; 12%) were 3 times more likely than non-Hispanic whites (n = 177; 75%) to present with advanced disease (OR, 3.8; 95% CI, 1.7-8.8). Young children were twice as likely as adolescents to present with advanced disease (OR, 2.2; 95% CI, 1.1-4.3). Distance to treatment center and SES did not affect stage of disease at presentation. Hispanics and those in the lowest SES quartile had a significantly higher mortality risk (hazard ratios, 3.0 [95% CI, 1.2-7.8] and 4.3 [95% CI, 1.4-13.9], respectively). In the adjusted survival model, only advanced disease was predictive of mortality (P < .001). CONCLUSION: Hispanics and young children with melanoma are more likely to present with advanced disease, and advanced disease is the single most important predictor of survival. Heightened awareness among physicians is needed to facilitate early detection of melanoma within these groups.

RESUMO

BACKGROUND: It is currently unclear whether the superior normal organ-sparing effect of intensity-modulated radiotherapy (IMRT) compared with 3-dimensional radiotherapy (3D) has a clinical impact on survival and cardiopulmonary mortality in patients with esophageal cancer (EC). METHODS: The authors identified 2553 patients aged > 65 years from the Surveillance, Epidemiology, and End Results (SEER)-Medicare and Texas Cancer Registry-Medicare databases who had nonmetastatic EC diagnosed between 2002 and 2009 and were treated with either 3D (2240 patients) or IMRT (313 patients) within 6 months of diagnosis. The outcomes of the 2 cohorts were compared using inverse probability of treatment weighting adjustment. RESULTS: Except for marital status, year of diagnosis, and SEER region, both radiation cohorts were well balanced with regard to various patient, tumor, and treatment characteristics, including the use of IMRT versus 3D in urban/metropolitan or rural areas. IMRT use increased from 2.6% in 2002 to 30% in 2009, whereas the use of 3D decreased from 97.4% in 2002 to 70% in 2009. On propensity score inverse probability of treatment weighting-adjusted multivariate analysis, IMRT was not found to be associated with EC-specific mortality (hazard ratio [HR], 0.93; 95% confidence interval [95% CI], 0.80-1.10) or pulmonary mortality (HR, 1.11; 95% CI, 0.37-3.36), but was significantly associated with lower all-cause mortality (HR, 0.83; 95% CI, 0.72-0.95), cardiac mortality (HR, 0.18; 95% CI, 0.06-0.54), and other-cause mortality (HR, 0.54; 95% CI, 0.35-0.84). Similar associations were noted after adjusting for the type of chemotherapy, physician experience, and sensitivity analysis removing hybrid radiation claims. CONCLUSIONS: In this population-based analysis, the use of IMRT was found to be significantly associated with lower all-cause mortality, cardiac mortality, and other-cause mortality in patients with EC.

RESUMO

PURPOSE: To investigate end-of-life care for Medicaid, Medicare, and dually eligible beneficiaries dying of cancer in Texas. METHODS: We analyzed the Texas Cancer Registry (TCR)-Medicaid and TCR-Medicare linked databases' claims data for 69,572 patients dying of cancer in Texas from 2000 to 2008. We conducted regression models in adjusted analyses of cancer-directed and acute care and total costs of care (in 2014 dollars) in the last 30 days of life. RESULTS: Medicaid patients were more likely to receive chemotherapy and radiation therapy. Medicaid patients were more likely to have >1 emergency room (ER) [odds ratio (OR)=5.27; 95% confidence interval (CI), 4.76-5.84], and were less likely to enroll in hospice (OR=0.59; 95% CI, 0.55-0.63) than Medicare patients. Dual eligibles were more likely to have >1 ER visit than Medicare-only beneficiaries (OR=1.19; 95% CI, 1.07-1.33). Black and Hispanic patients were more likely to experience >1 ER visit and >1 hospitalization than whites. Costs were higher for nonwhite Medicare, Medicaid, and dually eligible patients compared with white Medicare enrollees. CONCLUSIONS: Variation in acute care utilization and costs by race and payer suggest efforts are needed to address palliative care coordination at the end of life for Medicaid and dually eligible beneficiaries and minority patients dying of cancer.

RESUMO

PURPOSE: Hospitalizations among patients with cancer are common and costly and, if unplanned, may interrupt oncologic treatment. The rate of unplanned hospitalizations in the population of elderly patients with cancer is unknown. We sought to describe and quantify patterns and risk factors for early unplanned hospitalization among elderly patients with GI cancer. PATIENTS AND METHODS: We conducted a retrospective cohort study using linked Texas Cancer Registry and Medicare claims data from 2001 to 2009. Texas residents age 66 years or older initially diagnosed with GI cancer between 2001 and 2007 were included in the study. The unplanned hospitalization rate was estimated, and reasons for unplanned hospitalization were evaluated. Risk factors were identified using adjusted Cox proportional hazards modeling. RESULTS: Thirty thousand one hundred ninety-nine patients were included in our study, 59% of whom had one or more unplanned hospitalizations. Of 60,837 inpatient claims, 58% were unplanned. The rate of unplanned hospitalization was 93 events per 100 person-years. The most common reasons for unplanned hospitalization were fluid and electrolyte disorders, intestinal obstruction, and pneumonia. Multivariable analysis showed that black race; residing in census tracts with poverty levels greater than 13.3%; esophageal, gastric, and pancreatic cancer; advanced disease stage; high Charlson comorbidity index score; and dual eligibility for Medicare and Medicaid increased the risk for unplanned hospitalization (all P values < .05). CONCLUSION: Unplanned hospitalizations among elderly patients with GI cancer are common. Some of the top reasons for unplanned hospitalization are potentially preventable, suggesting that comorbidity management and close coordination among involved health care providers should be promoted.

RESUMO

PURPOSE: To compare the risk of hospitalization between patients with early-stage breast cancer who received different chemotherapy regimens. PATIENT AND METHODS: We identified 3,567 patients older than age 65 years from the SEER/Texas Cancer Registry-Medicare database and 9,327 patients younger than age 65 years from the MarketScan database who were diagnosed with early-stage breast cancer between 2003 and 2007. The selection was nonrandomized and nonprospectively collected. We categorized patients according to the regimens they received: docetaxel (T) and cyclophosphamide (C), doxorubicin (A) and C, TAC, AC + T, dose-dense AC + paclitaxel (P) or AC + weekly P. We compared the rates of chemotherapy-related hospitalizations that occurred within 6 months of chemotherapy initiation and used multivariable logistic regression analysis to identify the factors associated with these hospitalizations. RESULTS: Among patients younger than age 65 years, the hospitalization rates ranged from 6.2% (dose-dense AC + P) to 10.0% (TAC), and those who received TAC and AC + T had significantly higher rates of hospitalization than did patients who received TC. Among patients older than age 65 years, these rates ranged from 12.7% (TC) to 24.2% (TAC) and the rates of hospitalization of patients who received TAC, AC + T, AC, or AC + weekly P were higher than those of patients who received TC. CONCLUSION: TAC and AC + T were associated with the highest risk of hospitalization in patients younger than age 65 years. Among patients older than age 65 years, all regimens (aside from dose-dense AC + P) were associated with a higher risk of hospitalization than TC. Results may be affected by selection biases where less aggressive regimens are offered to frailer patients.

RESUMO

PURPOSE: We sought to analyze trends in radiation therapy (RT) technology use and costs in the last 30 days of life for patients dying as a result of cancer. METHODS: We used the Surveillance, Epidemiology, and End Results (SEER) -Medicare and Texas Cancer Registry-Medicare databases to analyze claims data for 13,488 patients dying as a result of lung, breast, prostate, colorectal, melanoma, and pancreas cancers from 2000 to 2009. Logistic regression modeling was used to conduct adjusted analyses regarding influence of demographic, clinical, and health services variables on receipt of types of RT. Costs were calculated in 2009 US dollars. RESULTS: The proportion of patients treated with two-dimensional RT decreased from 74.9% of those receiving RT in the last 30 days of life in 2000 to 32.7% in 2009 (P < .001). Those receiving three-dimensional RT increased from 27.2% in 2000 to 58.5% in 2009 (P < .001). The proportion of patients treated with intensity-modulated radiation therapy in the last 30 days of life increased from 0% in 2000 to 6.2% in 2009 (P < .001), and those undergoing stereotactic radiosurgery increased from 0% in 2000 to 5.0% in 2009 (P < .001). The adjusted mean costs of per-patient RT services delivered in the last 30 days of life were higher in the years 2007 to 2009. CONCLUSION: Among patients receiving RT in the last month of life, there was a shift away from the simplest technique toward more advanced RT technologies. Studies are needed to ascertain whether these technology shifts improve palliative outcomes and quality of life for patients dying as a result of cancer who receive RT services.

RESUMO

BACKGROUND: Intensity-modulated radiation therapy (IMRT) is a technologically advanced, and more expensive, method of delivering radiation therapy with a goal of minimizing toxicity. It has been widely adopted for head and neck cancers; however, its comparative impact on cancer control and survival remains unknown. The goal of this analysis was to compare the cause-specific survival (CSS) for patients with head and neck cancers treated with IMRT versus non-IMRT from 1999 to 2007. METHODS: CSS was determined using the Surveillance, Epidemiology, and End Results (SEER)-Medicare database and analyzed regarding treatment details, including the use of IMRT versus non-IMRT, using claims data. Hazard ratios (HRs) were estimated by the frailty model with a propensity score matching cohort and instrumental variable analysis. RESULTS: A total of 3172 patients were identified. With a median follow-up of 40 months, patients treated with IMRT had a statistically significant improvement in CSS compared with those treated with non-IMRT (84.1% versus 66.0%; P < .001). When each anatomic subsite was analyzed separately, all respective subgroups of patients treated with IMRT had better CSS than those treated with non-IMRT. In multivariable survival analyses, patients treated with IMRT were associated with better CSS (HR = 0.72, 95% confidence interval = 0.59 to 0.90 for propensity score matching; HR = 0.60, 95% confidence interval = 0.41 to 0.88 for instrumental variable analysis). CONCLUSIONS: Patients with head and neck cancers who were treated with IMRT experienced significant improvements in CSS compared with patients treated with non-IMRT techniques. This suggests there may be benefits to IMRT in cancer outcomes, in addition to toxicity reduction, for this patient population.

RESUMO

OBJECTIVE: Streptococcal bacteremia occurs during hematopoietic cell transplantation (HCT), and treatment of active oral disease may reduce this risk. The objective of this study was to determine the type, number, and costs of pre-transplantation dental procedures in this population. STUDY DESIGN: Data were collected retrospectively from the records of patients who were to undergo HCT. The type, number, and costs of dental procedures were determined based on median charges of MassHealth (the Medicaid program in Massachusetts) and also on the median "usual and customary" fees charged by dentists in Massachusetts. RESULTS: A total of 405 patients were evaluated. There were 243 men (60%) and 162 women, with a median age of 53 years. The median and average costs (in US dollars) of dental treatment before HCT were $275 and $384, respectively, for patients covered by MassHealth and $368 and $522, respectively, for those with private insurance, adjusted to 2012 levels. CONCLUSIONS: Dental evaluation before HCT is an economical way for patients to minimize the risk of localized infection and possibly reduce the risk of bacteremia that may prolong the length of hospitalization.

RESUMO

OBJECTIVE: Studies have shown that there is sufficient availability of mammography; however, little is known about geographic variation in capacity. The purpose of this study was to determine the locations and extent of over/undersupply of mammography in 14 southern states from 2002 to 2008. DATA SOURCES: Mammography facility data were collected from the U.S. Food and Drug Administration (FDA). Population estimates, used to estimate the potential demand for mammography, were obtained from GeoLytics Inc. STUDY DESIGN: Using the two-step floating catchment area method, we calculated spatial accessibility at the block group level and categorized the resulting index to represent the extent of under/oversupply relative to the potential demand. PRINCIPAL FINDINGS: Results show decreasing availability of mammography over time. The extent of over/undersupply varied significantly across the South. Reductions in capacity occurred primarily in areas with an oversupply of machines, resulting in a 68 percent decrease in the percent of women living in excess capacity areas from 2002 to 2008. The percent of women living in poor capacity areas rose by 10 percent from 2002 to 2008. CONCLUSIONS: Our study found decreasing mammography availability and capacity over time, with substantial variation across states. This information can assist providers and policy makers in their business planning and resource allocation decisions.

RESUMO

PURPOSE: Unlike infections related to chemotherapy-induced neutropenia, postoperative infections occurring in patients with solid malignancy remain largely understudied. Our aim is to evaluate the outcomes and the volume-outcomes relationship associated with postoperative infections following resection of common solid tumors. METHODS: We used Texas Discharge Data to study patients undergoing resection of cancer of the lung, esophagus, stomach, pancreas, colon, or rectum from 01/2002 to 11/2006. From their billing records, we identified ICD-9 codes indicating a diagnosis of serious postoperative infection (SPI), i.e., bacteremia/sepsis, pneumonia, and wound infection, occurring during surgical admission or leading to readmission within 30 days of surgery. Using regression-based techniques, we estimated the impact of SPI on mortality, resource utilization, and costs, as well as the relationship between hospital volume and SPI, after adjusting for confounders and data clustering. RESULTS: SPI occurred following 9.4 % of the 37,582 eligible tumor resections and was independently associated with nearly 12-fold increased odds of in-hospital mortality [95 % confidence interval (95 % CI), 7.2-19.5, P < 0.001]. Patients with SPI required six additional hospital days (95 % CI, 5.9-6.2) at an incremental cost of $16,991 (95 % CI, $16,495-$17,497). Patients who underwent resection at high-volume hospitals had a 16 % decreased odds of developing SPI than those at low-volume hospitals (P = 0.03). CONCLUSIONS: Due to the substantial burden associated with SPI following common solid tumor resections, hospitals must identify more effective prophylactic measures to avert these potentially preventable infections. Additional volume-outcomes research is needed to identify infection prevention processes that can be transferred from high- to lower-volume providers.

RESUMO

BACKGROUND: Men with prostate cancer who undergo androgen deprivation therapy (ADT) are at risk for bone loss and fractures. Our objective was to determine if Medicare beneficiaries with prostate cancer in the state of Texas underwent DXA scans when initiating ADT. METHODS: We identified men diagnosed with prostate cancer between 2005 and 2007 in the Texas Cancer Registry/Medicare linked database, and who received parenteral ADT or orchiectomy. We identified DXA claims within 1 year before or 6 months after starting ADT. We examined use of bone conservation agents in the subgroup of patients enrolled in Medicare Part D. Multivariate logistic regression models were used to examine determinants of DXA use. RESULTS: The analysis included 2,290 men (2,262 parenteral ADT, 28 orchiectomy); 197 (8.6 %) underwent DXA within 1 year before and 6 months after starting ADT. Men aged 75 years or older were more likely to undergo DXA than men aged 66-74 years (OR 1.5; 95 % CI 1.1-2.1). Those living in small urban areas were less likely to undergo DXA than those in big areas (OR 0.40; 95 % CI 0.19-0.82). Of the 1,060 men enrolled in Medicare part D, 59 (5.6 %) received bone conservation agents when starting ADT; 134 (12.6 %) either received bone conservation agents or underwent DXA. CONCLUSIONS: Fewer than one in ten Medicare beneficiaries with prostate cancer initiating ADT underwent a DXA exam. Variation in utilization was also related to residence area size. Further research is needed to identify whether the use of DXA in patients with prostate cancer receiving ADT will result in fracture prevention.

RESUMO

OBJECTIVES: To assess the feasibility of refining physician quality indicators of screening mammography use based on patient life expectancy. DESIGN: Retrospective population-based cohort study. SETTING: Texas. PARTICIPANTS: Three thousand five hundred ninety-five usual care providers (UCPs) with at least 10 female patients aged 67 and older on January 1, 2008, with an estimated life expectancy of 7 years or more (222,584 women) and at least 10 women with an estimated life expectancy of less than 7 years (90,903 women), based on age and comorbidity. MEASUREMENTS: Screening mammography use in 2008-09 by each provider in each population. RESULTS: The average adjusted mammography screening rates for UCPs were 31.1% for women with a life expectancy of less than 7 years and 55.2% for women with a life expectancy of 7 years or longer. For women with limited life expectancy, 3.7% of UCPs had significantly lower and 9.2% had significantly higher than average adjusted mammography screening rates. For women with longer life expectancy, 16.7% of UCPs had significantly lower and 19.7% had significantly higher than average rates. UCP adjusted screening rates were stable over time (2006-07 vs 2008-09, correlation coefficient (r) = 0.65, P < .001). There was a strong correlation between UCP screening rates for their female patients with a life expectancy of less than 7 years and 7 years or longer (r = 0.67, P < .001). Most physician characteristics associated with higher screening rates (e.g., being female and foreign trained) in women with longer life expectancy were also associated with higher screening rates in women with limited life expectancy. CONCLUSION: Providers with high mammography screening rates for women with longer life expectancy also tend to screen women with limited life expectancy. Quality indicators for screening practice can be improved by distinguishing appropriate use from overuse based on patient life expectancy.

RESUMO

BACKGROUND: Jaw complications, including osteoradionecrosis, are significant sequelae of radiation therapy (RT) for oral cancers. This study identifies the impact of patient, tumor, and treatment characteristics on the development of jaw complications in patients treated with RT. METHODS: The Surveillance, Epidemiology, and End Results (SEER)-Medicare database was used to identify patients treated with RT for oral cancers from 1999 to 2007. Jaw complications were identified by International Classification of Diseases 9th revision (ICD-9) diagnosis codes and/or related procedures using Current Procedural Terminology (CPT) and ICD-9 codes. RESULTS: A total of 1848 patients were identified. With a median follow-up of 2.5 years, 297 patients (16.1%) developed jaw complications: 226 patients had a diagnosis, 41 patients had a procedure, and 30 patients had both. On multivariate analysis, female sex, lack of chemotherapy use, and fewer comorbidities were associated with a statistically significant increase in jaw complications. CONCLUSIONS: Even with modern techniques, jaw complications are a notable and potentially devastating side effect of RT for oral cancers.

RESUMO

The goal of this study was to quantify the burden of cervical cancer in Texas and provide information about the health care needs of survivors. Data from multiple sources including the Texas Cancer Registry, Behavioral Risk Factor Surveillance System, and Texas Medicare claims were used in this effort. In 2009, there were over 100,000 cervical cancer survivors in Texas. Our descriptive analysis revealed that these women consumed less fruit and vegetables, were more often smokers, and had worse physical and mental health than women without a history of cancer. Survivors aged 65 and older cost Medicare over $15 million in inpatient, outpatient, and hospice care in 2009 alone, or $9,827 per cervical cancer survivor - nearly a third more than the average Medicare enrollee in Texas that year. Providers and public health practitioners can play an integral role in reducing the human and economic burden of cervical cancer in Texas through smoking cession and healthy lifestyle counseling for survivors, recommending the HPV vaccine to males and females aged 9-26, and continuing to offer cervical cancer screening for women up to age 65.

RESUMO

OBJECTIVES: To determine the level of adherence to medications and characteristics of Part D beneficiaries associated with higher levels of antihypertensive medication adherence. DESIGN: Retrospective cohort study. SETTING: Medicare claims and Part D event files. PARTICIPANTS: Medicare Part D enrollees with prevalent uncomplicated hypertension who filled at least one antihypertensive prescription in 2006 and two prescriptions in 2007. MEASUREMENTS: Medication adherence was defined as an average medication possession ratio of 80% or greater. Potential factors associated with adherence evaluated were age, sex, race or ethnicity, socioeconomic factors, comorbidity, medication use, copayments, being in the coverage gap, and number of unique prescribers. RESULTS: Overall adherence was 79.5% of 168,522 Medicare Part D enrollees with prevalent uncomplicated hypertension receiving antihypertensive medicines in 2007. In univariate analysis, adherence varied significantly according to most patient factors. In multivariable analysis, lower odds of adherence persisted for blacks (odds ratio (OR) = 0.53, 95% confidence interval (CI) = 0.51-0.55), Hispanics (OR = 0.58, 95% CI = 0.55-0.61), and other non-white races (OR = 0.80 95% CI = 0.75-0.85) than for whites. Greater comorbidity and concurrent medication use were also associated with poorer adherence. Adherence was significantly different across several geographic regions. CONCLUSION: A number of associations were identified between patient factors and adherence to antihypertensive drugs, with significant differences in adherence according to ethnicity. Improving adherence could have significant public health implications and could improve outcomes specific to hypertension, as well as improving cost and healthcare utilization.

RESUMO

BACKGROUND: Costs and benefits of emerging prostate cancer treatments for young men (age < 65 years) in the United States are not well understood. We compared utilization, clinical outcomes, and costs between two types of radical prostatectomy (RP)--minimally invasive prostatectomy (MIRP) and retropubic prostatectomy (RRP)--among young patients. METHODS: We extracted from LifeLink Health Plan Claims Database, a commercial claims database, information on 10,669 patients receiving either MIRP or RRP between 2003 and 2007. In unadjusted analyses, we used chi-square tests to compare clinical outcomes and nonparametric bootstrapping method to compare costs between the MIRP and RRP groups. We applied logistic, Cox proportional hazard, and extended estimation equation methods to examine the association between surgical modality and perioperative complications, anastomotic stricture, and costs while controlling for age, comorbidity, and health plan characteristics. RESULTS: The percentage of prostatectomies performed as MIRP increased from 5.7% in 2003 to 50.3% in 2007. Patients with more comorbidity were more likely to undergo RRP than MIRP. Compared with the RRP group, the MIRP group had a significantly lower rate of perioperative complications (23.0% vs. 30.4%; P < 0.001) and a lesser tendency for anastomotic strictures (hazard ratio 0.42; 95% CI 0.35-0.50) within the first postoperative year but had higher hospitalization costs ($19,998 vs. $18,424; P < 0.001) despite shorter hospitalizations (1.7 days vs. 3.1 days; P < 0.001). Similar findings were reported in the subgroup analysis of patients with comorbidity score 0. CONCLUSION: MIRP among nonelderly patients increased substantially over time. MIRP was found to have fewer complications. Lower costs of complications appeared to have offset higher hospitalization costs of MIRP.
