Socioeconomic Determinants of Health and Reflux Management: Insights from a Tertiary Medical Center.

To assess the correlation of social determinants of health (SDOH) with the general care patterns related to gastroesophageal reflux disease and laryngopharyngeal reflux. Determine correlation of SDOH on utilization rates for medication, reflux testing and surgical intervention for patients diagnosed with reflux. Describe overall care patterns for gastroesophageal reflux disease care at a tertiary academic facility. Retrospective chart review. Patient demographics (age, sex, race, ethnicity, and insurance status) were extracted for adults diagnosed with reflux between 2009 and 2019. Odds ratios (ORs) for the associations between sociodemographic factors and reflux treatment pathways were determined by chi-square analyses. A total of 143,786 patients were evaluated during the study period with a diagnosis code of reflux. A subgroup of 40,754 patients had objective reflux testing including Bravo, dual pH-impedance, manometry, esophagogastroduodenoscopy (EGD) and esophagram, but no significant difference in utilization rates was found. A total of 239 patients who failed medical management underwent fundoplication. White (OR 2.43, 95% confidence interval [CI] 1.56-3.70) and female (OR 1.37, 95% CI 1.05-1.79) patients were more likely to undergo fundoplication than Black (OR 0.42, 95% CI 0.25-0.70) and male (OR 0.72, 95% CI 0.55-0.95) patients. Patients with private insurance (OR 1.58, 95% CI 1.23-2.04) were more likely to undergo fundoplication than those with public insurance (OR 0.65, 95% CI 0.50-0.84). Male patients were less likely to undergo fundoplication (OR 0.69, 95% CI 0.49-0.98) among patients evaluated for reflux with EGD. SDOH correlate with patterns of reflux evaluation and management at our tertiary care center. IV Laryngoscope, 2024.

Medical imaging utilization in migrants compared with nonmigrants in a universal healthcare system: A population-based matched cohort study.

Medical imaging is an integral part of healthcare. Globalization has resulted in increased mobilization of migrants to new host nations. The association between migration status and utilization of medical imaging is unknown. A retrospective population-based matched cohort study was conducted in Ontario, Canada from April 1, 1995 to December 31, 2016. A total of 1,848,222 migrants were matched 1:1 to nonmigrants in the year of migration on age, sex, and geography. Utilization of computed tomography (CT), magnetic resonance imaging (MRI), radiography, and ultrasonography was determined. Rate differences per 1,000 person-years comparing migrants to nonmigrants were calculated. Relative rates were calculated using a recurrent event framework, adjusting for age, sex, and time-varying socioeconomic status, comorbidity score, and access to a primary care provider. Estimates were stratified by migration age: children and adolescents (≤19 years), young adults (20 to 39), adults (40 to 59), and older adults (≥60). Utilization rates of CT, MRI, and radiography were lower for migrants across all age groups compared with Ontario nonmigrants. Increasing age at migration was associated with larger differences in utilization rates. Older adult migrants had the largest gap in imaging utilization. The longer the time since migration, the larger the gap in medical imaging use. In multivariable analysis, the relative rate of imaging was approximately 20% to 30% lower for migrants: ranging from 0.77 to 0.88 for CT and 0.72 to 0.80 for MRI imaging across age groups. Radiography relative rates ranged from 0.84 to 0.90. All migrant age groups, except older adults, had higher rates of ultrasonography. The indication for imaging was not captured, thus it was not possible to determine if the imaging was necessary. Migrants utilized less CT, MRI, and radiography but more ultrasonography. Older adult migrants used the least amount of imaging compared with nonmigrants. Future research should evaluate whether lower utilization is due to barriers in healthcare access or health-seeking behaviors within a universal healthcare system.

Improving Racial and Ethnic Disparities in Outpatient Anterior Cervical Discectomy and Fusion Driven by Increasing Utilization of Ambulatory Surgical Centers in New York State.

Retrospective cohort study. The purpose of this study was to assess trends in disparities in utilization of hospital outpatient departments (HOPDs) and ambulatory surgical centers (ASCs) for outpatient ACDF (OP-ACDF) between White, Black, Hispanic, and Asian/Pacific Islander patients from 2015 to 2018 in New York State. Racial and ethnic disparities within the field of spine surgery have been thoroughly documented. To date, it remains unknown how these disparities have evolved in the outpatient setting alongside the rapid emergence of ASCs and whether restrictive patterns of access to these outpatient centers exist by race and ethnicity. We conducted a retrospective review from 2015 to 2018 using the Healthcare Cost and Utilization Project (HCUP) New York State Ambulatory Database. Differences in utilization rates for OP-ACDF were assessed and trended over time by race and ethnicity for both HOPDs and freestanding ASCs. Poisson regression was used to evaluate the association between utilization rates for OP-ACDF and race/ethnicity. Between 2015 and 2018, Black, Hispanic, and Asian patients were less likely to undergo OP-ACDF compared with White patients in New York State. However, the magnitude of these disparities lessened over time, as Black, Hispanic, and Asian patients had greater relative increases in utilization of HOPDs and ASCs for ACDF when compared with White patients ( Ptrend <0.001). The magnitude of the increase in freestanding ASC utilization was such that minority patients had higher ACDF utilization rates in freestanding ASCs by 2018 ( P <0.001). We found evidence of improving racial disparities in the relative utilization of outpatient ACDF in New York State. The increase in access to outpatient ACDF appeared to be driven by an increasing number of patients undergoing ACDF in freestanding ASCs in large metropolitan areas. These improving disparities are encouraging and contrast previously documented inequalities in inpatient spine surgery. III.

A family nurse-led intervention for reducing health services’ utilization in individuals with chronic diseases: The ADVICE pilot study

ObjectivesIntensive health services’ utilization is common in older individuals affected by chronic diseases. This study assessed whether a structured family nurse-led educational intervention would be effective in reducing health services’ use (readmissions and/or emergency service access) among older people affected by chronic conditions. MethodsThis is a non-randomized before-after pilot study. A sample of 78 patients was recruited from two general practices in Italy and 70 among them were followed for 8 months. Standard home care was provided during the first four months’ period (months 1–4), followed by the educational intervention until the end of the study (months 5–8). The intervention, based on the teach-back method, consisted of by-weekly 60-min home sessions targeting aspects of the disease and its treatment, potential complications, medication adherence, and health behaviours. Rates of health services’ use were collected immediately before (T0), and after the interventions (T1). Differences in utilization rates were examined by the McNemar’s test. Potential factors associated with the risk of health services’ use were explored with a Cox proportional hazard regression model. ResultsThe sample (n = 78) was predominantly female (n = 50, 64.1%), and had a mean age of 76.2 (SD = 4.8) years. Diabetes mellitus was the most frequent disease (n = 27, 34.6%). McNemar’s test indicated a significant reduction in health services’ use at T1 (McNemar χ2 = 28.03, P < 0.001). Cox regressions indicated that time and patient education, as well as their interaction, were the only variables positively associated with the probability of health services’ use. ConclusionA teach-back intervention led by a family nurse practitioner has the potential to reduce health services’ use in older patients with chronic diseases.

Racial and Gender Shoulder Arthroplasty Utilization Disparities of High- and Low-Volume Centers in New York State.

IntroductionThe literature has consistently demonstrated utilization disparities in joint replacement procedures, though no studies have evaluated disparities in total shoulder arthroplasty with regard to operative volume.MethodsWe queried the New York (NY) Statewide Planning and Research Cooperative System (SPARCS) database for 32 410 total shoulder arthroplasties performed between 2009 and 2017. Patients were identified using Clinical Classifications Software code 154 for Non-Hip/Knee Arthroplasty and All Patient Refined-Diagnosis Related Group code 322 for Shoulder. Racial groups included Hispanic, non-Hispanic white, non-Hispanic black, and Other. High-volume centers were facilities that performed 2 standard deviations above the mean annual procedures. Utilization rates were calculated by dividing total shoulder arthroplasties per group by the 2010 NY Census population of that group. The Fisher exact test was used to determine significance.ResultsTotal shoulder arthroplasty utilization increased from 43/100 000 to 73/100 000, two-thirds of which was driven by an increase in white resident utilization. More White residents per 100 000 underwent shoulder arthroplasty than Black, Hispanic, and Other residents per 100 000 residents of their respective race. White residents were 90% more likely than Hispanic residents to undergo total shoulder arthroplasty at high-volume centers (P = .04). There were no differences in utilization rate regarding operative volume comparing Black or Other residents to White residents. More females underwent total shoulder arthroplasty than males, though there was no difference in utilization rate regarding operative volume.ConclusionThough total shoulder arthroplasty utilization nearly doubled, disparities persisted across gender and minority groups particularly in Hispanic utilization as White residents were 90% more likely than Hispanic residents to undergo shoulder arthroplasty at high-volume centers.

Sex and racial disparity in utilization and outcomes of t-PA and thrombectomy in acute ischemic stroke

Background/purpose: Racial/ethnic and sex disparity may occur in stroke throughout the continuum of care. Endovascular therapy (EVT) became standard of care in 2015 for eligible patients with acute ischemic stroke (AIS). We evaluated for racial and sex differences in t-PA and EVT utilization and outcomes in 2016 in the National Inpatient Sample. Methods: Treatment rates for t-PA, EVT, and t-PA+EVT and outcomes including home discharge, in-hospital mortality and prolonged length of stay (pLOS) were evaluated by sex and race. Multivariate survey-logistic regression was performed to evaluate outcomes. ResultsThe study had 468,630 patients – 49.3% men, 50.7% women; 69.3% whites, and 30.7% non-whites. There was no difference in treatment utilization by sex, women vs men for t-PA (7.65% vs 7.76%; aOR:1.02; 95% CI:0.97–1.07), EVT (1.74% vs 1.67%; aOR:1.09; 95% CI:0.99–1.20) and t-PA+EVT (0.57% vs 0.57%; aOR:1.01; 95% CI:0.85–1.21); and by race, non-white vs white for t-PA (7.62% vs 7.74%; aOR:0.98; 95% CI:0.93–1.05), EVT (1.62% vs 1.74%; aOR:0.91; 95% CI:0.78–1.07), and t-PA+EVT(0.59% vs 0.56%; aOR:1.05; 95% CI:0.84–1.30). Compared to men, women treated with t-PA had less home discharge (37.2% vs 46.3%; aOR:0.81; 95% CI:0.72–0.90), more in-hospital mortality (5.7% vs 3.9%; aOR:1.37; 95% CI:1.06–1.77) and less pLOS (8.3% vs 9.6%; aOR:0.82; 95% CI:0.69–0.98); women treated with EVT had less home discharge (15.8% vs 23.7%; aOR:0.69; 95% CI:0.52-0.91). Compared to whites, non-whites treated with t-PA had lower odds of home discharge (42.1% vs 41.6%; aOR:0.79; 95% CI:0.69–0.90), less in-hospital mortality (3.7% vs 5.3%; aOR:0.65; 95% CI:0.49–0.87), and higher pLOS (11.4% vs 7.9%; aOR:1.3; 95% CI:1.07–1.56); non-whites treated with EVT had less home discharge (18%vs 20.2%; aOR:0.70; 95% CI:0.51–0.97) and higher pLOS (35.1% vs 24%; aOR:1.52; 95% CI:1.16–1.99). Conclusion: Sex and racial disparity exists for outcomes of t-PA and EVT despite no difference in utilization rates.

Do Transgender and Gender Diverse Individuals Receive Adequate Gynecologic Care? An Analysis of a Rural Academic Center.

Purpose: The transgender population faces disparities accessing gynecologic health care services, especially in rural settings. There is limited knowledge among medical providers regarding transgender-specific gynecologic care.Methods: A retrospective chart review of 255 transgender and gender diverse patients at a rural, academic center and associated ambulatory clinics was performed. Demographics, insurance status, and utilization rates of screening services, including cervical cancer, breast cancer, human papillomavirus (HPV) vaccination status, and contraceptive status, were analyzed using descriptive statistics. These rates were compared with national rates of cisgender individuals. Chi-square tests were performed to assess the association of insurance status with receipt of services.Results: Prevalence of HPV vaccination was lowest among transgender men (20%) compared with transgender women (60%) and gender nonbinary/nonconfirming and gender diverse individuals (60%), p<0.001. Our cohort was significantly less likely to receive Papanicolaou smears (51% vs. 81%, p<0.05) and contraception (48% vs. 65%, p<0.05) than cisgender individuals. Around 18% of transgender women had a documented pelvic examination in the past year. There was no significant difference in utilization rates based on insurance status.Conclusion: In our rural setting, there is lower utilization of gynecologic services among transgender and gender diverse individuals. Although participants in our study had high rates of access to insurance and health care providers, they still had lower rates of gynecologic screening and prevention services. To address these disparities, we advocate for developing transgender-specific gynecologic health maintenance guidelines, robust provider education, and an inclusive electronic medical record to ensure appropriate gynecologic health screening.

Cervical disc replacement: examining "real-world" utilization of an emerging technology.

Cervical disc replacement (CDR) has emerged as an alternative to anterior cervical discectomy and fusion (ACDF) for the management of cervical spondylotic pathology. While much is known about the efficacy of CDR within the constraints of a well-controlled, experimental setting, little is known about general utilization. The authors present an analysis of temporal and geographic trends in "real-world" utilization of CDR among those enrolled in private insurance plans in the US. Eligible subjects were identified from the IBM MarketScan Databases between 2009 and 2017. Individuals 18 years and older, undergoing a single-level CDR or ACDF for cervical radiculopathy and/or myelopathy, were identified. US Census divisions were used to classify the region where surgery was performed. Two-level mixed-effects regression modeling was used to study regional differences in proportional utilization of CDR, while controlling for confounding by regional case-mix differences. A total of 47,387 subjects met the inclusion criteria; 3553 underwent CDR and 43,834 underwent ACDF. At a national level, the utilization of single-level CDR rose from 5.6 cases for every 100 ACDFs performed in 2009 to 28.8 cases per 100 ACDFs in 2017. The most substantial increases occurred from 2013 onward. The region of highest utilization was the Mountain region (Arizona, Colorado, Idaho, Montana, Nevada, New Mexico, Utah, and Wyoming), where 14.3 CDRs were performed for every 100 ACDFs (averaged over the 9-year period of study). This is in contrast to the East South Central region (Alabama, Kentucky, Mississippi, and Tennessee), where only 2.1 CDRs were performed for every 100 ACDFs. Patient factors that significantly increased the odds of undergoing a CDR were age younger than 40 years (OR 15.9 [95% CI 10.0-25.5]; p < 0.001), no clinical evidence of myelopathy/myeloradiculopathy (OR 1.5 [95% CI 1.4-1.7]; p < 0.001), and a Charlson Comorbidity Index score of 0 (OR 2.7 [95% CI 1.7-4.2]; p < 0.001). After controlling for these factors, significant differences in utilization rates remained between regions (chi-square test = 830.4; p < 0.001). This US national level study lends insight into the rate of uptake and geographic differences in utilization of the single-level CDR procedure. Further study will be needed to ascertain specific factors that predict adoption of this technology to explain observed geographic discrepancies.

Racial and Socioeconomic Disparities in Access and Utilization of Adrenal Metastasectomy.

There is substantial evidence that resecting adrenal metastases can be safely accomplished and extend overall survival in select patients. However, patient access to this operation has not been studied at the population level. The purpose of this study was to determine differences in utilization rates of adrenal metastasectomy (ADMX) across patient populations. The Healthcare Utilization Project National Inpatient Sample was used to identify patients who had adrenal metastases (ADM) and who underwent ADMX from 2007 to 2011. Patients were identified by ICD-9-CM diagnosis and procedure codes. Predictor variables included sex, race, median household income, and primary insurance payer. Primary outcomes included receiving an ADMX and same hospitalization mortality. Secondary outcomes included length of stay, infection, cardiac, pulmonary, and renal complications. Univariable and multivariable logistic regression models were used to identify statistical associations. 32,331 ADM and 1070 ADMX patients identified in the database. Despite similar comorbidities, Black patients had 0.30 (95% CI 0.21-0.41) lower odds to receive an ADMX compared to White patients. Medicaid patients had 0.38 (0.28-0.52) less odds and Private Insurance patients 1.18 (1.00-1.39) more odds to receive an ADMX compared to Medicare patients. Women had a 1.39 (1.22-1.58) higher odds ratio of undergoing ADMX compared to men. Of the ADMX cohort, there was no difference in same hospitalization mortality or surgical complications. Black and Medicaid patients underwent fewer adrenal metastasectomies despite similar comorbidities and postoperative outcomes. This suggests a potential disparity in access to this treatment that disproportionately affects Black and low-income patients, and prompts further study, outreach attempts, as well as, research into improving access.

Care choices in Europe: To Each According to His or Her Needs?

Growing long-term care (LTC) needs represent a major challenge for our aging societies. Understanding how utilization patterns of different types of care are influenced by LTC policies or changes in the population composition such as age patterns or health can provide helpful insight on how to adequately prepare for this situation. To this aim, this paper explores how individuals choose between different forms of LTC. We exploit variation between countries as well as between individuals within countries using data from the Survey of Health, Ageing, and Retirement in Europe (SHARE). Using nonlinear decomposition techniques, we break down the difference in utilization rates between countries into differences based on observed sociodemographic and need-related characteristics and differences in the impacts of these characteristics, which allows us to identify the drivers behind differences in the formal-informal care mix. Our results show that a substantial fraction of the observed country differences can be explained by differences in impacts. We argue that this is a result of the different incentives provided by the different LTC systems.

The role of marijuana use disorder in predicting emergency department and inpatient encounters: A retrospective cohort study

BackgroundMarijuana use disorder (MUD) is the most common illegal drug use disorder and its prevalence is increasing. It is associated with psychiatric and medical problems, but little is known about its impact on emergency department (ED) and inpatient utilization rates. DesignIn a retrospective cohort design, we used electronic health record (EHR) data to identify patients with MUD (n=2752) and demographically matched patients without MUD (n=2752) in 2010. Logistic regressions determined risk of ED and inpatient visits each year from 2010 to 2014 for MUD patients versus controls; mixed-effect growth models examined differences in utilization rates over 5-years. Patient characteristics predicting increased risk of utilization were examined among the MUD sample only. Key resultsRates of ED (OR=0.87, p<0.001) and inpatient (OR=0.76, p<0.001) services use significantly declined over 5 years for all patients. Patients with MUD exhibited a significantly greater decline in ED (OR=0.81, p<0.001) and inpatient (OR=0.64, p<0.001) use relative to controls. However, MUD patients had significantly greater risk of having ED and inpatient visits at each time point (p’s<0.001). MUD patients with co-occurring other substance use, medical, and/or psychiatric disorders had a greater risk of having ED or inpatient encounters over 5 years (p’s<0.001). ConclusionsMUD patients remain at high risk for ED and inpatient visits despite decreasing utilization rates over 5 years. Addressing MUD patients’ comorbid conditions in outpatient settings may help reduce inappropriate service use.

Utilisation of cancer screening services by disabled women in Chile.

BackgroundResearch has shown that women with disabilities face additional challenges in accessing and using healthcare services compared to non-disabled women. However, relatively little is known about the utilisation of cancer screening services for women with disabilities. This study addresses this gap by examining the utilisation of the Papanicolaou test and mammography for disabled women in Chile.MethodsWe used cross-sectional data, taken from a 2015 nationally-representative survey. Initially, we employed logistic regressions to test for differences in utilisation rates for the Papanicolaou test (66,281 observations) and the mammogram (35,294 observations) between disabled and non-disabled women. Next, logistic regressions were used to investigate the demographic, socioeconomic, and health-related factors affecting utilisation rates for cancer screening services for disabled women (sample sizes: 5,823 observations for the Papanicolaou test and 5,731 observations for the mammogram).ResultsDisabled women were less likely to undergo screening tests than non-disabled women. For the Papanicolaou test and mammography, the multivariable regression models showed that living in rural areas, having higher education, being affiliated with a private health insurance company, giving a good health self-assessment score, and being under medical treatment for other illnesses were associated with higher utilisation rates. On the other hand, being single, inactive with regard to employment, and having a better income were linked with lower utilisation. While utilisation rates for both disabled and non-disabled women have increased since 2006, the utilisation disparity has slightly increased.ConclusionsThis study shows the influence of various factors in the utilisation rates of preventive cancer screening services for disabled women. To develop effective initiatives targeting inequalities in the utilisation of cancer screening tests, it is important to move beyond an exclusively single-disease approach and acknowledge the complexity of the patient population.

Comparison of Inhospital Mortality and Frequency of Coronary Angiography on Weekend Versus Weekday Admissions in Patients With Non–ST-Segment Elevation Acute Myocardial Infarction

Patients with myocardial infarction admitted on weekends have been reported to less frequently undergo invasive angiography and experience poorer outcomes. We used the Nationwide Inpatient Sample database (2003 to 2011) to compare differences in all-cause inhospital mortality between patients admitted on a weekend versus weekday for an acute non-ST-segment elevation myocardial infarction (NSTEMI) and to determine if rates and timing of coronary revascularization contributed to this difference. A total of 3,625,271 NSTEMI admissions were identified, of which 909,103 (25.1%) were weekend and 2,716,168 (74.9%) were weekday admissions. Admission on a weekend versus weekday was independently associated with lower rates of coronary angiography (odds ratio [OR] 0.88; 95% confidence interval [CI] 0.89 to 0.90; p <0.001) or utilization of an early invasive strategy (EIS) (OR 0.480; 95% CI 0.47 to 0.48; p <0.001). Unadjusted inhospital mortality was significantly higher for the cohort of patients admitted on weekends (adjusted OR 1.02; 95% CI 1.01 to 1.04; p <0.001). However, this disparity was no longer significant after adjustment for differences in rates of utilization of EIS (OR 1.01; 95% CI 0.99 to 1.03; p= 0.11). In conclusion, this study demonstrates that among patients admitted with a diagnosis of an acute NSTEMI, admission on a weekend was associated with higher inhospital mortality compared with admission on a weekday and that lower rates of utilization of EIS contributed significantly to this disparity.

Randomized Controlled Study on Safety and Feasibility of Transfusion Trigger Score of Emergency Operations.

Background:Due to the floating of the guideline, there is no evidence-based evaluation index on when to start the blood transfusion for patients with hemoglobin (Hb) level between 7 and 10 g/dl. As a result, the trigger point of blood transfusion may be different in the emergency use of the existing transfusion guidelines. The present study was designed to evaluate whether the scheme can be safely and effectively used for emergency patients, so as to be supported by multicenter and large sample data in the future.Methods:From June 2013 to June 2014, patients were randomly divided into the experimental group (Peri-operative Transfusion Trigger Score of Emergency [POTTS-E] group) and the control group (control group). The between-group differences in the patients’ demography and baseline information, mortality and blood transfusion-related complications, heart rate, resting arterial pressure, body temperature, and Hb values were compared. The consistency of red blood cell (RBC) transfusion standards of the two groups of patients with the current blood transfusion guideline, namely the compliance of the guidelines, utilization rate, and per-capita consumption of autologous RBC were analyzed.Results:During the study period, a total of 72 patients were recorded, and 65 of them met the inclusion criteria, which included 33 males and 32 females with a mean age of (34.8 ± 14.6) years. 50 underwent abdomen surgery, 4 underwent chest surgery, 11 underwent arms and legs surgery. There was no statistical difference between the two groups for demography and baseline information. There was also no statistical differences between the two groups in anesthesia time, intraoperative rehydration, staying time in postanesthetic care unit, emergency hospitalization, postoperative 72 h Acute Physiologic Assessment and Chronic Health Evaluation II scores, blood transfusion-related complications and mortality. Only the POTTS-E group on the 1st postoperative day Hb was lower than group control, P < 0.05. POTTS-E group was totally (100%) conformed to the requirements of the transfusion guideline to RBC infusion, which was higher than that of the control group (81.25%), P < 0.01. There were no statistical differences in utilization rates of autologous blood of the two groups; the utilization rates of allogeneic RBC, total allogeneic RBC and total RBC were 48.48%, 51.5%, and 75.7% in POTTS-E group, which were lower than those of the control group (84.3%, 84.3%, and 96.8%) P < 0.05 or P < 0.01. Per capita consumption of intraoperative allogeneic RBC, total allogeneic RBC and total RBC were 0 (0, 3.0), 2.0 (0, 4.0), and 3.1 (0.81, 6.0) in POTTS-E groups were all lower than those of control group (4.0 [2.0, 4.0], 4.0 [2.0, 6.0] and 5.8 [2.7, 8.2]), P < 0.05 or P < 0.001.Conclusions:Peri-operative Transfusion Trigger Score-E evaluation scheme is used to guide the application of RBC. There are no differences in the recent prognosis of patients with the traditional transfusion guidelines. This scheme is safe; Compared with doctor experience-based subjective assessment, the scoring scheme was closer to patient physiological needs for transfusion and more reasonable; Utilization rate and the per capita consumption of RBC are obviously declined, which has clinical significance and is feasible. Based on the abovementioned three points, POTTS-E scores scheme is safe, reasonable, and practicable and has the value for carrying out multicenter and large sample clinical researches.

1:27 PM, Abstract No. 269 - Safety and efficacy of renal cryoablation for small renal masses: midterm follow-up

database, all patients with stage T1aN0M0 RCC (r4cm) diagnosed in 2004 to 2011 were identified. Sociodemographic trends in use of surgery vs. TA were evaluated by chi-square and logistic regression. Overall survival (OS) was estimated using Kaplan-Meier from the time of diagnosis. Difference in utilization rate of TA in 2004-2007 vs. 2008-2011 was observed. Results: Of 28351 patients with T1a lesion, 2133 (7.5%) did not receive curative therapy. Of 26218 patients who received curative therapy, the majority underwent surgical resection: 24992 (95.3%) surgical resection, 671(2.6%) CRA, 553(2.1%) (po0.001). While mean overall survival was similar between the surgery (81.1 months) and TA (81.0 months) group (p1⁄40.612). Those who did not receive curative therapy had a significantly shorter mean OS (70.4 mo; po0.001) when compared to curative group as a whole. Furthermore, mean OS for TA group was also significantly prolonged compared to no curative therapy group (po0.001). Being unmarried, Z65 years of age, being insured, living in metropolitan areas, in Pacific Coast region, and residing in areas with higher median family income demonstrated higher likelihoods of receiving TA when compared to surgery (po0.001). There was a significant increase in the rate of use of TA compared to surgery in more recent years (3.2% in 2004-2007 vs. 5.3% in 2008-2011 (po0.001)). Older age, being unmarried, living in rural areas with lower median family income and lower educational status were found to be predictor of not receiving therapy. Conclusion: There was significant disparity in the management of T1a RCC lesions, in part affected by patient’s sociodemographic determinants. In addition, there was significant underutilization of less invasive thermal ablation which demonstrated similar survivorship compared to surgery and significantly prolonged survival compared to no therapy.

Race-ethnicity and gender differences in VA health care service utilization among U.S. veterans of recent conflicts.

The purpose of this study was to compare health care utilization patterns by race-ethnicity and gender among veterans returning from Iraq and Afghanistan. A retrospective analysis was conducted with records from U.S. service members and veterans returning from Iraq and Afghanistan who enrolled in health care through the Veterans Health Administration, who received a psychiatric diagnosis, and who had used primary or mental health outpatient care between October 7, 2001, and December 31, 2012 (N=309,050). Racial-ethnic minority groups were first collapsed together and compared with whites and then separated by racial-ethnic group. Gender was also tested as a moderator of utilization. Although rates of mental health outpatient care, primary care, and emergency service utilization were relatively similar for racial-ethnic minority groups and whites, minority groups were admitted to psychiatric inpatient care at lower rates than whites. When veterans were separately categorized by specific racial-ethnic groups, some differences in utilization rates emerged; most notably, only black and Hispanic men were admitted less frequently to psychiatric inpatient care, and male and female Asian/Pacific Islander veterans used emergency services less, than their white counterparts. Gender moderated the association between race-ethnicity and mental health outpatient use, such that American Indian and Hispanic women used mental health outpatient services less than white women, but American Indian and Hispanic men showed the opposite pattern. Furthermore, black men were more likely than white men to use mental health outpatient services, but there was no difference between these women. Although service utilization rates between minority groups and whites were similar when minority groups were combined, examination of utilization by racial-ethnic groups and by men and women separately yielded more robust findings.

Sex differences in characteristics, utilization, and outcomes of patient undergoing total elbow arthroplasty: a study of the US nationwide inpatient sample.

The aim of this study was to compare patient characteristics, utilization rates, and outcomes after total elbow arthroplasty (TEA) by sex. We used the nationwide inpatient sample from 1998 to 2011 to study sex-related time trends in patient characteristics, comorbidity, and outcomes after TEA. We used chi-squared test, analysis of variance, and the Cochran-Armitage test to assess differences in utilization rates and characteristics over time by sex and logistic regression to compare mortality, discharge disposition, and the length of hospital stay by sex. Overall TEA utilization 0.45 in 1998 to 0.96 per 100,000 in 2011 (p < 0.0001). The utilization rates were significantly higher in females compared to males throughout the study period: 0.62 vs. 0.29 in 1998 (p < 0.0001) and 1.31 vs. 0.70 in 2011 (p < 0.0001). Compared to males, females undergoing TEA were more likely to be white (79.7 vs. 71.4 %; p < 0.0001), have rheumatoid arthritis (16.7 vs. 8.1 %; p < 0.0001), and have Deyo-Charlson index of 2 or more (11.3 vs. 5.9 %; p < 0.0001) and were older (63.5 vs. 51.4 years; p < 0.0001). Compared to males undergoing TEA, females had significantly lower mortality, 0.1 vs. 0.4 % (p = 0.03); lower proportion were discharged to home, 81.9 vs. 89.6 % (p < 0.0001), and fewer had has index hospital stay above the median, 30.0 vs. 33.0 % (p = 0.01); most differences were significant after multivariable adjustment. TEA utilization in the USA more than doubled in the last 14 years, with rates higher in females than males. Females had better outcomes after TEA than men. Preoperative risk communication should be sex-specific based on these data.

Decadal analysis of deceased organ donation in Spain and the United States linking an increased donation rate and the utilization of older donors

After the foundation of the National Transplant Organization, Spanish rates of deceased donor donation rapidly outpaced US growth over the decade from 1989 to 1999. An analysis of the following decade, 1999-2009, demonstrated a markedly flattened growth curve for Spanish deceased donor organ procurement, which increased only 2.4% from 33.6 to 34.4 donors per million population (pmp). In comparison, over the same decade in the United States, the rate of deceased donation increased from 20.9 to 26.3 donors pmp (25.8%). An age group comparison demonstrated a much higher donation rate among older donors in Spain. For example, the number of donors older than 70 years increased from 3.8 to 8.8 pmp (a 132% increase), and they now constitute 25.4% of all Spanish organ donors. In contrast, the number of US donors older than 70 years increased from 1.0 to 1.3 pmp, and they constitute only 4.4% of total deceased donors. Over the same decade, the number of younger donors (15-30 years old) decreased from 6.6 to 2.5 pmp (a 62% decrease) in Spain, and this contrasted with a slightly increased US donation rate for the same age subgroup (a 15.5% increase from 5.8 to 6.7 pmp). Although older donors were more rarely used in the United States, growth in donation over the 2 decades (1989-2009) was strongly associated with the utilization of donors aged 65 or older (P < 0.01). United Network for Organ Sharing regions demonstrated significant differences in utilization rates for older donors. In conclusion, strategies aimed toward achieving US donation rates equivalent to the Spanish benchmark should target improved utilization rates for older donors in the United States instead of emulating elements of the Spanish organ procurement system.

Healthcare Utilization and Symptom Variation Among Veterans Using Behavioral Telehealth Center Services

Substance use and mental health problems are often underdiagnosed and undertreated in primary care. Veterans affairs facilities are using the Behavioral Telehealth Center (BTC) to provide evidence-based assessments for primary care patients via telephone. Whether participation in BTC services is associated with (1) increases in healthcare utilization and (2) decreases in symptoms based on behavioral health screening instruments, post-BTC services compared with pre-BTC services were investigated. Retrospective data were extracted for 1,820 patients who were referred to the BTC. Differences in utilization rates and symptom scores pre- and post-BTC services were tested using repeated measures analysis of covariance while controlling for relevant sociodemographic variables. Participants (1) utilized significantly more substance use and mental health treatment services and (2) had significantly lower alcohol and depression screening scores post-BTC services compared with pre-BTC services. This initial evaluation provides support that BTC services are associated with increased healthcare utilization and decreased alcohol and depressive symptoms.
