The impact of travel distance in patient outcomes following revascularization for chronic limb-threatening ischemia.

BACKGROUND: Patient travel distance to the hospital is a key metric of individual and social disadvantage and its impact on the management and outcomes following intervention for chronic limb-threatening ischemia (CLTI) is likely underestimated. We sought to evaluate the effect of travel distance on outcomes in patients undergoing first-time lower extremity revascularization at our institution. METHODS: We retrospectively reviewed all consecutive patients undergoing first-time lower extremity revascularization, both endovascular and open, for CLTI from 2005 to 2014. Patients were stratified into 2 groups based on travel distance from home to hospital greater than or less than 30 miles. Outcomes included reintervention, major amputation, restenosis, primary patency, wound healing, length of stay, length of follow-up and mortality. Kaplan-Meier estimates were used to determine event rates. Logistic and cox regression was used to evaluate for an independent association between travel distance and these outcomes. RESULTS: Of the 1293 patients were identified, 38% traveled >30 miles. Patients with longer travel distances were younger (70 years vs 73 years; P = .001), more likely to undergo open revascularization (65% vs 41%; P < .001), and had similar Wound, Ischemia, foot Infection stages (P = .404). Longer distance travelled was associated with an increase in total hospital length of stay (9.6 days vs 8.6 days; P = .031) and shorter total duration of postoperative follow-up (2.1 years vs 3.0 years; P = .001). At 5 years, there was no definitive difference in the rate of restenosis (hzard ratio [HR], 1.3; 95% confidence interval [CI], 0.91-1.9; P = .155) or reintervention (HR, 1.4; 95% CI, 0.96-2.1; P = .065), but longer travel distance was associated with an increased rate of major amputation (HR, 2.1; 95% CI, 1.2-3.7; P = .011), and death (HR, 1.6; 95% CI, 1.2-2.2; P = .002). Longer travel distance was also associated with higher rate of nonhealing wounds (HR, 2.3; 95% CI, 1.5-3.5; P = .001). CONCLUSIONS: Longer patient travel distance was found to be associated with a lower likelihood of limb salvage and survival in patients undergoing first-time lower extremity revascularization for CLTI. Understanding and addressing the barriers to discharge, need for multidisciplinary follow-up, and appropriate postoperative wound care management will be key in improving outcomes at tertiary care regional specialty centers.

Sustainability in radiation oncology: opportunities for enhancing patient care and reducing CO2 emissions in breast cancer radiotherapy at selected German centers.

BACKGROUND AND OBJECTIVE: Radiotherapy often entails a substantial travel burden for patients accessing radiation oncology centers. The total travel distance for such treatments is primarily influenced by two factors: fractionation schedules and the distances traveled. Specific data on these aspects are not well documented in Germany. This study aims to quantify the travel distances for routine breast cancer patients of five radiation oncology centers located in metropolitan, urban, and rural areas of Germany and to record the CO2 emissions resulting from travel. METHODS: We analyzed the geographic data of breast cancer patients attending their radiotherapy treatments and calculated travelling distances using Google Maps. Carbon dioxide emissions were estimated assuming a standard 40-miles-per-gallon petrol car emitting 0.168 kg of CO2 per kilometer. RESULT: Addresses of 4198 breast cancer patients treated between 2018 and 2022 were analyzed. Our sample traveled an average of 37.2 km (minimum average: 14.2 km, maximum average: 58.3 km) for each radiation fraction. This yielded an estimated total of 6.2 kg of CO2 emissions per visit, resulting in 156.2 kg of CO2 emissions when assuming 25 visits (planning, treatment, and follow-up). CONCLUSION: Our study highlights the environmental consequences associated with patient commutes for external-beam radiotherapy, indicating that reducing the number of treatment fractions can notably decrease CO2 emissions. Despite certain assumptions such as the mode of transport and possible inaccuracies in patient addresses, optimizing fractionation schedules not only reduces travel requirements but also achieves greater CO2 reductions while keeping improved patient outcomes as the main focus.

Traveling Long Distances for Rectal Cancer Care: Institutional Outcomes and Patient Experiences.

INTRODUCTION: Mounting evidence supports traveling to high-volume centers for complex surgical procedures, such as a proctectomy, yet the burden of travel and outcomes of patients traveling long distances is not yet clear. Thus, we aimed to evaluate oncologic outcomes, quality of life, and travel burdens for patients treated for rectal cancer at a single tertiary-care institution. METHODS: A retrospective study of patients treated with proctectomy for locally advanced rectal cancer was performed comparing long and short travel distance (STD) cohorts. Primary outcome measures included overall mortality, disease recurrence, and quality of life. Secondary outcomes included out-of-pocket expenses. The cohorts were compared using Wilcoxon rank-sum and Chi-square tests for continuous and categorical variables, respectively. Kaplan-Meier plots were created to evaluate overall and disease-free survival. RESULTS: Among 102 patients, 51 (50%) were classified as long travel distance (LTD, mean 57.8 miles) and 51 (50%) were classified as STD (mean 12.8 miles). There was no statistical difference in 5-y mortality (4% LTD versus 4% STD, P = 1.000), disease recurrence (26% LTD versus 18% STD, P = 0.336), or quality of life (0.85 LTD versus 0.87 STD, P = 0.690). The LTD cohort did have significantly lower postresection compliance with surveillance (84% LTD versus 96% STD, P = 0.046). LTD cohort also had significantly more lodging ($77.1 LTD versus $0 STD, P = 0.025) and transportation expenses ($133.6 LTD versus $92.6 STD, P = 0.010). CONCLUSIONS: As the surgical management of rectal cancer becomes increasingly centralized, this study found patients who traveled long-distances received comparable care with outcomes similar to those who lived locally. Higher travel costs and lower compliance with surveillance were identified as barriers to care in the long-distance population, but a number of solutions can be implemented to address these issues.

Cost analysis of telemedicine use in paediatric nephrology-the LMIC perspective.

BACKGROUND: The overall cost of managing chronic diseases is a significant barrier to accessing complete and timely healthcare, especially in rural and geographically isolated areas. This cost disparity becomes more pronounced in the case of children and more so in under-resourced regions of the world. In the era of COVID-19, as the need for physical distancing increased, there was a transition in approach to healthcare provision to telemedicine consultations. This study evaluates the cost saving using teleconsultations in a paediatric nephrology clinic. METHODS: This prospective cohort study was conducted at AIIMS Jodhpur, a tertiary care centre in western Rajasthan from March 2021 to October 2022. All consecutive paediatric (29 days-18 years) patients attending telemedicine services for kidney-related illness were enrolled. Basic demographic details were collected. Cost analysis was done after 6 months, regarding perceived cost savings for the patient and family by using telehealth for follow-up during 6 months starting from enrolment. RESULTS: A total of 112 patients were enrolled; 266 teleconsultations attended; 109 patients who could be followed up saved INR 457,900 during 6 months of follow-up. The average cost saving was INR - 1577/patient/visit. Patients saved 4.99% of the family income (median 2.16% (IQR 0.66-5.5)). The highest expenditure per visit was incurred for food and transport. The median distance from the residence to the clinic was 122.5 km (IQR 30-250). Over the 6-month study period, patients saved a travel distance of 83,274 km (743 km/patient). CONCLUSIONS: The use of telemedicine as a follow-up method helps save significant costs and distances travelled by patients.

Musculoskeletal patients' preferences for care from physiotherapists or support workers: a discrete choice experiment.

BACKGROUND: Delegation of clinical tasks from physiotherapists to physiotherapy support workers is common yet varies considerably in musculoskeletal outpatient physiotherapy services, leading to variation in patient care. This study aimed to explore patients' preferences and estimate specific trade-offs patients are willing to make in treatment choices when treated in musculoskeletal outpatient physiotherapy services. METHODS: A discrete choice experiment was conducted using an efficient design with 16 choice scenarios, divided into two blocks. Adult patients with musculoskeletal conditions recruited from a physiotherapy service completed a cross-sectional, online questionnaire. Choice data analyses were conducted using a multinomial logit model. The marginal rate of substitution for waiting time to first follow-up physiotherapy appointment and distance from the physiotherapy clinic was calculated and a probability model was built to estimate the probability of choosing between two distinct physiotherapy service options under different scenarios. RESULTS: 382 patient questionnaires were completed; 302 participants were treated by physiotherapists and 80 by physiotherapists and support workers. There was a significant preference to be seen by a physiotherapist, have more follow-up treatments, to wait less time for the first follow-up appointment, to be seen one-to-one, to see the same clinician, to travel a shorter distance to get to the clinic and to go to clinics with ample parking. Participants treated by support workers did not have a significant preference to be seen by a physiotherapist and it was more likely that they would choose to be seen by a support worker for clinic scenarios where the characteristics of the physiotherapy service were as good or better. CONCLUSIONS: Findings highlight that patients treated by support workers are likely to choose to be treated by support workers again if the other service characteristics are as good or better compared to a service where treatment is provided only by physiotherapists. Findings have implications for the design of physiotherapy services to enhance patient experience when patients are treated by support workers. The findings will contribute to the development of "best practice" recommendations to guide physiotherapists in delegating clinical work to physiotherapy support workers for patients with musculoskeletal conditions.

Impact of Travel Distance on Surgical Outcomes of Patients Surgically Treated for Non-Small Cell Lung Cancer: A Single-Center Study in Ehime, Japan.

Travel burden is a poor prognostic factor for many cancers worldwide because it hinders optimal diagnosis and treatment planning. Currently, the impact of travel burden on survival after surgery for non-small cell lung cancer (NSCLC) in Japan is largely unexplored. We examined the impact of travel distance on the postoperative outcomes of patients with NSCLC in Ehime Prefecture, Japan. The data of 1212 patients who underwent surgical resection for NSCLC were retrospectively reviewed. Patients were divided into quartiles based on the travel distance from their home to the hospital (≤ 13 km, 13-40 km, 40-57 km, and > 57 km) in Ehime Prefecture. We found no significant differences among the quartiles in baseline clinicopathological characteristics, including sex, smoking status, histology, surgical procedure, clinical stage, and pathological stage. Overall survival (OS) and relapse-free survival (RFS) also were not significantly different among the travel distance quartiles. We conclude that travel distance did not impact OS or RFS among patients with NSCLC who underwent surgical resection at our institution.

The impact of distance to facility on treatment modality, short-term outcomes, and survival of patients with HPV-positive oropharyngeal squamous cell carcinoma.

PURPOSE: This study compared treatment and outcomes for patients with HPV-positive oropharyngeal squamous cell carcinoma (OPSCC) based on their travel distance to treatment facility. MATERIALS AND METHODS: Patients with cT1-4, N0-3, M0 HPV-positive OPSCC in the National Cancer Database from 2010 to 2019 were identified and split into four quartiles based on distance to facility, with quartile 4 representing patients with furthest travel distances. Multivariable-adjusted logistic regression and Cox proportional hazards modeling were used to analyze the primary outcome of treatment received, and secondary outcomes of clinical stage, overall survival, surgical approach (i.e., TORS versus other), and 30-day surgical readmissions. RESULTS: 17,207 patients with HPV-positive OPSCC were evenly distributed into four quartiles. Compared to patients in quartile 1, patients in quartile 4 were 40 % less likely to receive radiation versus surgery (OR = 0.60; 95 % CI = 0.54-0.66). Among the patients who received surgery, quartile 4 had a higher odds of receiving TORS treatment compared to quartile 1 (4v1: OR = 2.38; 95 % CI = 2.05-2.77), quartile 2 (4v2: OR = 2.31, 95 % CI = 2.00-2.66), and quartile 3 (4v3: OR = 1.75; 95 % CI = 1.54-1.99). Quartile 4 had a decreased odds of mortality compared to Quartile 1 (4v1: OR = 0.87; 95 % CI = 0.79-0.97). There were no differences among the quartiles in presenting stage and 30-day readmissions. CONCLUSIONS: This study found that patients with furthest travel distance to facility were more often treated surgically over non-surgical management, with TORS over open surgery, and had better overall survival. These findings highlight potential disparities in access to care for patients with HPV-positive OPSCC.

Factors associated with survival of patients with advanced lung cancer and long travel distances.

BACKGROUND/PURPOSE: Patients with advanced cancer sometimes travel to locations that have the treatment that they need. We explored the prognostic factors of survival in patients with advanced lung cancer who travel long distances in Taiwan. METHODS: We obtained data from the National Taiwan University Hospital (NTUH) Integrated Medical Database. Patients who received a diagnosis of stage IV lung cancer from 2010 to 2019 and were treated in NTUH and its Hsinchu and Yunlin branches were enrolled. Factors associated with survival were analyzed using a Cox hazard regression model. RESULTS: In total, 6178 patients with stage IV lung cancer were enrolled. Young age, female sex, smaller primary tumor size, better performance, and non-squamous cell non-small cell histology were independently associated with longer survival. Treatment in medical centers and long travel distances (>50 km) were associated with longer survival in the univariate analysis but not in the multivariate analysis (hazard ratio [HR]: 1.04, p = 0.361; HR: 0.99, p = 0.775, respectively). Participation in clinical trials was associated with longer survival in the univariate (HR: 0.53, p < 0.001) and multivariate analyses (HR: 0.62, p < 0.001). For the 1144 patients in the Hsinchu area, enrolment in clinical trials was an independent prognostic factor (HR: 0.72, p = 0.040), whereas treatment in medical centers was not (HR: 0.95, p = 0.635). CONCLUSION: Long travel distances and treatment in medical centers were not independently associated with survival for patients with advanced lung cancer. Enrolment in clinical trials was an independent prognostic factor.

Travel Distance and Spanish-Speaking are Associated with Delays in the Treatment of Cleft Palate.

OBJECTIVE: Delayed repair of cleft palate is associated with worse speech outcomes. Social determinants of health may influence the timing of surgery; however, there are no population health investigations to evaluate factors such as travel distance, language barriers, and payer. This study sought to identify factors that may interfere with timely cleft palate repair. DESIGN: Retrospective cohort. SETTING: National/multi-center. PATIENTS/PARTICIPANTS: All cleft palate repairs within California were extracted from 2000-2021. MAIN OUTCOMES MEASURES: The primary outcome was age at surgical repair, which was modeled with linear regression. Covariates included race, primary language, distance from patient home to hospital, socioeconomic status, primary payer, and managed care enrollment status. RESULTS: 11 260 patients underwent surgical repair of a cleft palate. Black race was associated with delayed repair (22 additional days, P = .004, 95% CI 67.00-37.7) along with Asian/Pacific-Islander race (11 additional days, P = .006, 95% CI 3.26-18.9) compared to white race. Spanish-speaking patients had significantly later cleft palate repairs by 19 days, (P < .001, 95% CI 10.8-27.7) compared with English-speaking. Further distances from the hospital were significantly associated with later cleft surgeries with out-of-state patients undergoing surgery 52 days later (P < .001, 95% CI 11.3-24.3). Managed care plans and Medi-Cal were significantly associated with earlier surgical repair compared with private insurance. CONCLUSION: Black, Asian Pacific Islander, and Spanish-speaking patients and greater distance traveled to hospital were associated with delayed cleft palate repairs. These results underscore the importance of addressing structural and social barriers to care to improve outcomes and reduce health disparities for patients with cleft palate.

Effect of rurality and travel distance on contralateral prophylactic mastectomy for unilateral breast cancer.

PURPOSE: Despite lack of survival benefit, demand for contralateral prophylactic mastectomy (CPM) to treat unilateral breast cancer remains high. High uptake of CPM has been demonstrated in Midwestern rural women. Greater travel distance for surgical treatment is associated with CPM. Our objective was to examine the relationship between rurality and travel distance to surgery with CPM. METHODS: Women diagnosed with stages I-III unilateral breast cancer between 2007 and 2017 were identified using the National Cancer Database. Logistic regression was used to model likelihood of CPM based on rurality, proximity to metropolitan centers, and travel distance. A multinomial logistic regression model compared factors associated with CPM with reconstruction versus other surgical options. RESULTS: Both rurality (OR 1.10, 95% CI 1.06-1.15 for non-metro/rural vs. metro) and travel distance (OR 1.37, 95% CI 1.33-1.41 for those who traveled 50 + miles vs. < 30 miles) were independently associated with CPM. For women who traveled 30 + miles, odds of receiving CPM were highest for non-metro/rural women (OR 1.33 for 30-49 miles, OR 1.57 for 50 + miles; reference: metro women traveling < 30 miles). Non-metro/rural women who received reconstruction were more likely to undergo CPM regardless of travel distance (ORs 1.11-1.21). Both metro and metro-adjacent women who received reconstruction were more likely to undergo CPM only if they traveled 30 + miles (ORs 1.24-1.30). CONCLUSION: The impact of travel distance on likelihood of CPM varies by patient rurality and receipt of reconstruction. Further research is needed to understand how patient residence, travel burden, and geographic access to comprehensive cancer care services, including reconstruction, influence patient decisions regarding surgery.

Travel Burden as a Measure of Healthcare Access and the Impact of Telehealth within the Veterans Health Administration.

BACKGROUND: Travel is a major barrier to healthcare access for Veteran Affairs (VA) patients, and disproportionately affects rural Veterans (approximately one quarter of Veterans). The CHOICE/MISSION acts' intent is to increase timeliness of care and decrease travel, although not clearly demonstrated. The impact on outcomes remains unclear. Increased community care increases VA costs and increases care fragmentation. Retaining Veterans within the VA is a high priority, and reduction of travel burdens will help achieve this goal. Sleep medicine is presented as a use case to quantify travel related barriers. OBJECTIVE: The Observed and Excess Travel Distances are proposed as two measures of healthcare access, allowing for quantification of healthcare delivery related to travel burden. A telehealth initiative that reduced travel burden is presented. DESIGN: Retrospective, observational, utilizing administrative data. SUBJECTS: VA patients with sleep related care between 2017 and 2021. In-person encounters: Office visits and polysomnograms; telehealth encounters: virtual visits and home sleep apnea tests (HSAT). MAIN MEASURES: Observed distance: distance between Veteran's home and treating VA facility. Excess distance: difference between where Veteran received care and nearest VA facility offering the service of interest. Avoided distance: distance between Veteran's home and nearest VA facility offering in-person equivalent of telehealth service. KEY RESULTS: In-person encounters peaked between 2018 and 2019, and have down trended since, while telehealth encounters have increased. During the 5-year period, Veterans traveled an excess 14.1 million miles, while 10.9 million miles of travel were avoided due to telehealth encounters, and 48.4 million miles were avoided due to HSAT devices. CONCLUSIONS: Veterans often experience a substantial travel burden when seeking medical care. Observed and excess travel distances are valuable measures to quantify this major healthcare access barrier. These measures allow for assessment of novel healthcare approaches to improve Veteran healthcare access and identify specific regions that may benefit from additional resources.

The impact of the distance traveled between residence and gestational trophoblastic neoplasia reference center and clinical outcomes in Brazilian women.

OBJECTIVE: To relate the distance traveled from the patient's residence to the gestational trophoblastic neoplasia (GTN) reference center (RC) and the occurrence of unfavorable clinical outcomes, as well as to estimate the possible association between this distance and the risk of metastatic disease at presentation, the need for multiagent chemotherapy to achieve remission and loss to follow-up before remission. STUDY DESIGN: Retrospective historical cohort study of patients with GTN followed at 8 Brazilian GTN-RC, from January 1st, 2000 - December 31st, 2017. RESULTS: Evaluating 1055 cases of GTN, and using a receiver operating characteristic curve, we found a distance of 56 km (km) from the residence to the GTN-RC (sensitivity = 0.57, specificity = 0.61) best predicted the occurrence of at least one of the following outcomes: occurrence of metastatic disease, need for multiagent chemotherapy to achieve remission, or loss to follow-up during chemotherapy. Multivariate logistic regression adjusted by age, ethnicity, marital status and the reference center location showed that when the distance between residence and GTN-RC was ≥56 km, there was an increase in the occurrence of metastatic disease (relative risk - RR:3.27; 95%CI:2.20-4.85), need for multiagent chemotherapy (RR:1.36; 95%CI:1.05-1.76), loss to follow-up during chemotherapy (RR:4.52; 95CI:1.93-10.63), occurrence of chemoresistance (RR:4.61; 95%CI:3.07-6.93), relapse (RR:10.27; 95%CI:3.08-34.28) and death due to GTN (RR:3.62; 95%CI:1.51-8.67). CONCLUSIONS: The distance between the patient's residence and the GTN-RC is a risk factor for unfavorable outcomes, including death from this disease. It is crucial to guarantee these patients get prompt access to the GTN-RC and receive follow-up support.

Travel distance and social vulnerability index: Impact on liver-related mortality among patients with end-stage liver disease.

INTRODUCTION: The reasons for the geographic disparities in liver-related mortality across the US remain ill-defined. We sought to investigate the impact of travel distance to liver transplantation (LT) programs and social vulnerability on county differences in liver-related mortality. METHODS: Data on LT registrants were obtained from the Scientific Registry of Transplant Recipients Standard Analytic Files (SRTR SAFs) between 2004 and 2019. Liver-related mortality data were obtained from the Center for Disease Control and Prevention's Wide-ranging Online Data for Epidemiologic Research (CDC WONDER) platform. Spatial epidemiological clustering of county-level LT registration and liver-related mortality rates was determined using local Moran's I. Comparison analyses assessed social vulnerability index (SVI) and travel distance within various county clusters. RESULTS: Among 151 864 LT waitlist registrants who were diagnosed with liver disease due to hepatitis C virus (HCV) or hepatitis B virus (HBV) (n = 68 479, 45.1%), alcohol (n = 38 328, 25.2%), non-alcoholic steatohepatitis (NASH) (n = 17 485, 11.5%), liver tumors (n = 16 644, 11.0%), and other diseases (n = 10 928, 7.2%), median SVI was 59.3 (IQR, 40.1-83.4). SVI (76.2 vs. 24.3, p < .001) was greater in the highest versus lowest liver-related mortality quartiles. The travel distances to LT centers (143.1 miles vs. 107.2 miles, p < .001) was longer in the lowest versus highest LT registration quartiles. Counties with low LT registration rates and high liver-related mortality rates were associated with long travel distances and high SVI. In contrast, while counties with high LT registration rates and high liver-related mortality rates had comparable SVI, travel distance was relatively shorter. CONCLUSION: Counties with greater SVIs were associated with higher liver-related mortality, with the highest SVI  counties having the highest overall liver-related mortality. Longer travel distances were associated with higher liver-related mortality. These findings highlight the impact of social determinants of health (SDOH) on liver disease outcomes.

Clinical features and outcome of retinoblastoma at the Vietnam National Cancer Hospital.

OBJECTIVES: To characterize the clinical features, treatment, and outcome of children diagnosed with retinoblastoma (RB) at Vietnam National Cancer Hospital. METHODS: The study enrolled all RB patients newly diagnosed at Vietnam National Cancer Hospital from January 2018 to December 2022. The primary endpoint was overall survival (OS) and the eye salvage rate. RESULTS: In total, 139 patients were enrolled, 51.8% patients were male. Median age was 18.9 months. Most patients presented with leukocoria (63.3%), followed by strabismus (14.4%), and 43.9% had bilateral disease. Of 200 eyes, 129 (64.5%) were classified as group E. Extraocular extension was noted in 10 of 139 patients (7.2%). About one-third of the patients lived more than 300 kilometers (km) away from these hospitals, and 17.3% of the patients belonged to minority groups, both of which were dominated by group E and extraocular or high-risk eyes at the time of consultation. Primary enucleation was done for 57 eyes (28.5%), and 51 of 61 patients (83.6%) received eye salvage therapy in bilateral RB group. At study closure, 127 children were alive at the last follow-up, 12 cases were confirmed dead. The 5-year OS and progression-free survival (PFS) rates were 90.3% and 85.9%, respectively. In particular, ethnic minority, distance to hospital more than 150 km, and extraocular disease were significantly associated with higher mortality among children with RB treated in Vietnam National Cancer Hospital. CONCLUSIONS: There is a need to support for screening RB with early symptoms in grassroots medical facilities and raise awareness among patients' families through health education programs. Besides, caring and supporting treatment for patients from the ethnic minority and who live far from hospitals are also extremely necessary.

Access to Left Ventricular Assist Device: Travel Time Does Not Tell The Whole Story.

BACKGROUND: Negative health effects of traveling longer distances for surgical services have been reported. Given the high complexity of multidisciplinary care required for management of Left Ventricular Assist Device (LVAD) implantation, only 4 of 18 centers in our state perform these operations. Given the limited access we hypothesized increased travel time would adversely affect postoperative outcomes and 30-d mortality. METHODS: A statewide Society of Thoracic Surgeons database was queried to identify patients undergoing Heartmate II/III and HVAD implantation, and 725 patients were identified. Travel time was calculated by zip code. Patients were stratified into regional and distant groups by the upper quartile of travel time (1-h). Preoperative variables and outcomes were compared between the groups. Multivariate analysis was performed to evaluate the impact of travel time in risk-adjusted models of 30-d mortality. RESULTS: Median patient travel time to their LVAD center in our state is 32 min (mean 53 ± 65 min, 46 ± 71 miles). Patients in the distant group (n = 191) had lower median incomes, higher self-pay status, higher rates of medical comorbid disease. Despite these differences there was no difference between the groups in ICU and/or hospital length of stay, readmission, postoperative complications, or 30-d mortality. Multivariate regression demonstrated insurance status, age, and prior surgery predicted 30-d mortality, but not travel time. CONCLUSIONS: Despite only four centers in the state performing LVAD implantation, travel time was strongly associated with preoperative risk, and socioeconomic status but not postoperative outcomes or 30-d mortality. Therefore, increasing access should focus on insurance, and patient characteristics not travel time.

Insurance Status and Travel Distance to Single Treatment Facility Predictive of Mastectomy.

BACKGROUND: We evaluated the impact of insurance status and travel distance on the receipt of total mastectomy without reconstruction (TM) compared to breast conserving surgery with radiation (BCT) for early-stage breast cancer (BC) patients who received care at a single facility. We hypothesized that, lack of insurance and increased travel distance would be predictive of TM over BCT and disparities would vary by different races and/or ethnicities. METHODS: Using the National Cancer Database from 2010-2017, we examined surgical patients with stage I or II BC, who received care at one facility. Chi-square tests examined subgroup differences by BCT or TM. Multivariable logistic regressions evaluated patient, facility, and pathologic factors associated with the receipt of TM over BCT for the entire cohort and by races and/or ethnicities. RESULTS: Of the 284,202 patients, 70.1% received BCT while 29.9% received TM. After adjustment travel distance > 60 miles to a treatment facility, and non-insured patients were more likely to receive TM over BCT, when compared to travel distance < 20 miles and private insurance (all P < 0.05). Compared to other races and/or ethnicities, African Americans traveling > 60 miles were 65.4% more likely to receive TM over BCT compared to those traveling < 20 miles (P < .0001). Across all races and/or ethnicities after adjustment, lack of insurance was predictive for receipt of TM over BCT (P < 0.05). CONCLUSIONS: Despite treatment at one facility, increased travel distance and insurance status are independently predictive of the receipt of TM over BCT in patients with early-stage BC. While travel distance is particularly impactful for African Americans, the impact of not having insurance on surgical treatments is universal across all races and/or ethnicities.

Impact of travel burden on clinical outcomes in lung cancer.

PURPOSE: Our study explores the influence of travel burden (measured as travel distance and travel time) on clinical outcomes in lung cancer patients. METHODS: A retrospective analysis of a single Bulgarian center was performed. A total of 9240 lung cancer patients were included in the study. Travel distance and travel time between patients' city of residence and the treating facility were calculated with an online tool to determine the shortest route for travel using the existing road network. The probability of survival was estimated using the Kaplan-Meier method, and differences in survival in each subgroup were evaluated with a log-rank test. RESULTS: About one third of all included patients were living in the same city as the treating facility (n = 2746, 29.7%). Overall survival in our patient population was significantly lower with increasing travel distance (p < 0.001, Mantel-Cox log rank) and travel time (p < 0.001, Mantel-Cox log rank). The 1-year OS rate according to travel distance was 27.1% in the same city group, 22.4% in < 50-km group, and 20.5% in ≥ 50-km group (p < 0.001). The corresponding values for the 5-year OS rate were 2.9%, 2.6%, and 1.4% (p < 0.001). CONCLUSION: In this retrospective study, we discovered significant differences in the overall survival of patients with lung cancer depending on travel distance and travel time to the treating oncological facility. Despite having similar clinical and pathological characteristics (age, sex, stage at initial diagnosis, histologic subtype), the median overall survival was significantly lower in those subgroups of patients with a higher travel burden.

National travel distances for emergency care.

BACKGROUND: Most emergency department (ED) patients arrive by their own transport and, for various reasons, may not choose the nearest ED. How far patients travel for ED treatment may reflect both patients' access to care and severity of illness. In this study, we aimed to examine the travel distance and travel time between a patient's home and ED they visited and investigate how these distances/times vary by patient and hospital characteristics. METHODS: We randomly sampled and collected data from 14,812 patients discharged to the community (DTC) between January and March 2016 from 50 hospital-based EDs nationwide. We geocoded and calculated the distance and travel time between patient and hospital-based ED addresses, examined the travel distances/ times between patients' home and the ED they visited, and used mixed-effects regression models to investigate how these distances/times vary by patient and hospital characteristics. RESULTS: Patients travelled an average of 8.0 (SD = 10.9) miles and 17.3 (SD = 18.0) driving minutes to the ED. Patients travelled significantly farther to avoid EDs in lower performing hospitals (p < 0.01) and in the West (p < 0.05) and Midwest (p < 0.05). Patients travelled farther when visiting EDs in rural areas. Younger patients travelled farther than older patients. CONCLUSIONS: Understanding how far patients are willing to travel is indicative of whether patient populations have adequate access to ED services. By showing that patients travel farther to avoid a low-performing hospital, we provide evidence that DTC patients likely do exercise some choice among EDs, indicating some market incentives for higher-quality care, even for some ED admissions. Understanding these issues will help policymakers better define access to ED care and assist in directing quality improvement efforts. To our knowledge, our study is the most comprehensive nationwide characterization of patient travel for ED treatment to date.

Impact of age, rurality and distance in predicting contralateral prophylactic mastectomy for breast cancer in a Midwestern state: a population-based study.

PURPOSE: Iowa is among several rural Midwestern states with the highest proportions of contralateral prophylactic mastectomy (CPM) in women < 45 years of age. We evaluated the role of rurality and travel distance in these surgical patterns. METHODS: Women with unilateral breast cancer (2007-2017) were identified using Iowa Cancer Registry records. Patients and treating hospitals were classified as metro, nonmetro, and rural based on Rural-Urban Continuum Codes. Differences in patient, tumor, and treatment characteristics and median travel distance (MTD) were compared. Characteristics associated with CPM were evaluated with multivariate logistic regression. RESULTS: 22,158 women were identified: 57% metro, 26% nonmetro and 18% rural. Young rural women had the highest proportion of CPM (52%, 39% and 40% for rural, metro, nonmetro women < 40 years). Half of all rural women had surgery at metro hospitals; these women had the longest MTD (62 miles). Among all women treated at metro hospitals, rural women had the highest proportion of CPM (17% rural vs 14% metro/nonmetro, p = 0.007). On multivariate analysis, traveling ≥ 50 miles (ORs 1.43-2.34) and rural residence (OR = 1.29) were independently predictive of CPM. Other risk factors were young age (< 40 years: OR = 7.28, 95% CI 5.97-8.88) and surgery at a metro hospital that offers reconstruction (OR = 2.30, 95% CI 1.65-3.21) and is not NCI-designated (OR = 2.34, 95% CI 1.92-2.86). CONCLUSION: There is an unexpectedly high proportion of CPM in young rural women in Iowa, and travel distance and availability of reconstructive services likely influence decision-making. Improving access to multidisciplinary care in rural states may help optimize decision-making.

Triiodothyronine and cortisol levels in the face of energetic challenges from reproduction, thermoregulation and food intake in female macaques.

Energy availability drives an individual's fitness and can be affected by diverse energetic challenges. The assessment of hormones involved in metabolic activity and energy mobilization provides a gateway to the study of physiological adaptations in response to changes in energy availability. Here, we investigated immunoreactive urinary total triiodothyronine (uTT3, thyroid hormone secreted through the hypothalamus-pituitary-thyroid axis and regulating the basal metabolic rate) alongside glucocorticoids (i.e. urinary cortisol, uCort, secreted through the hypothalamus-pituitary-adrenal axis and mediating energy mobilization) in wild female Assamese macaques (Macaca assamensis). Combining more than 2900; of behavioral data from 42 adult females with physiological data from 382 urine samples, we evaluated both uTT3 and uCort in relation to potential energetic challenges encountered by a female, namely fluctuations in energy intake, travel distance, reproductive state and minimum ambient temperature. As predicted, levels of both hormones changed in response to variation in energy intake with a tendency toward a positive effect on uTT3 and a significant negative effect on uCort levels. Unexpectedly, neither hormone was influenced by variation in travel distance. Reproductive state affected both hormones with higher levels of uTT3 and uCort in the second half of gestation. Finally, a decrease of minimum temperature triggered an increase in uCort but unexpectedly not in uTT3. Collectively, our results highlight the respective contribution of two endocrine axes when facing energetic challenges and the underlying metabolic strategies to cope with them. Overall, assessing thyroid hormones together with glucocorticoids provides an integrative picture in the evaluation of an individual's energy status.
