Geographic Access to Health Care for Rural Medicare Beneficiaries

CONTEXT: Patients in rural areas may use less medical care than those living in urban areas. This could be due to differences in travel distance and time and a utilization of a different mix of generalists and specialists for their care. PURPOSE: To compare the travel times, distances, and physician specialty mix of all Medicare patients living in Alaska, Idaho, North Carolina, South Carolina, and Washington. METHODS: Retrospective design, using 1998 Medicare billing data. Travel time was determined by computing the road distance between 2 population centroids: the patient's and the provider's zone improvement plan codes. FINDINGS: There were 2,220,841 patients and 39,780 providers in the cohort, including 6,405 (16.1%) generalists, 24,772 (62.3%) specialists, and 8,603 (21.6%) nonphysician providers. There were 20,693,828 patient visits during the study. The median overall 1-way travel distance and time was 7.7 miles (interquartile range 1.9-18.7 miles) and 11.7 minutes (interquartile range 3.0-25.7 minutes). The patients in rural areas needed to travel 2 to 3 times farther to see medical and surgical specialists than those living in urban areas. Rural residents with heart disease, cancer, depression, or needing complex cardiac procedures or cancer treatment traveled the farthest. Increasing rurality was also related to decreased visits to specialists and an increasing reliance on generalists. CONCLUSIONS: Residents of rural areas have increased travel distance and time compared to their urban counterparts. This is particularly true for rural residents with specific diagnoses or those undergoing specific procedures. Our results suggest that most rural residents do not rely on urban areas for much of their care.     

Effects of Physician Outreach Programs on Rural-Urban Differences in Breast Cancer Management

In 1986 to 1987, urban-rural differences in several breast cancer management practices were noted in Illinois data. Several intervention programs for physicians were initiated to improve rural patients' access to state-of-the-art breast cancer management to reduce these differences. This report compares an intensive rural oncology outreach intervention program with a lower intensity physician education program. Medical records from 1986 to 1991 were reviewed on 2,277 breast cancer patients in a 12-county study area. The care received by urban patients was compared with three groups of rural patients: those managed in rural hospitals with intensive oncology outreach programs beginning in 1988 (Rural group 1), and in those rural hospitals with less intensive interventions using an audit with feedback strategy beginning in 1989 (Rural group 2). Rural patients who traveled to one of the urban facilities also were included in the analysis because the less intensive interventions also took place in these facilities, and these patients showed unique patterns of care in the baseline analysis (Rural Group 3). The years 1986 to 1987 constituted the baseline, and 1990 to 1991 constituted the final evaluation period. Chi square and multivariate analyses were conducted to compare the effect of the two types of interventions on changing breast cancer management practices and reducing the urban-rural differences. By the final evaluation period, the high intensity intervention was not more successful in reducing or eliminating the urban-rural differences than the low intensity intervention for many practices. However, often the frequency estimates were higher in Rural Group 1, which received the high intensity intervention. The changes noted in Rural Group 3 were not always the same as in Rural Group 2, even though both received the same low intensity interventions, lending evidence to the observation that travel distance and other nonmedical factors affect the choices of management modalities for these patients. Finally, given the nonrandomized study design, other explanations for the changes could not be ruled out.     

Improving Rural Cancer Patients'' Outcomes: A Group-Randomized Trial

CONTEXT: Significant barriers exist in the delivery of state-of-the-art cancer care to rural populations. Rural providers' knowledge and practices, their rural health care delivery systems, and linkages to cancer specialists are not optimal; therefore, rural cancer patient outcomes are less than achievable. PURPOSE: To test the effects of a strategy targeting rural providers and their practice environment on patient travel for care, satisfaction, economic barriers, and health-related quality of life. METHODS: A group-randomized trial was conducted with 18 rural communities in the north-central United States. Twelve of these communities were included and defined as the unit of analysis for the patient outcomes portion of the study. The intervention targeted rural providers and their practice environment. The subjects were patients with breast, colorectal, lung, and prostate cancers from the rural communities. The main outcomes were patients' travel to obtain health care, satisfaction with care, perceptions of economic barriers to care, and health-related quality of life. In total, 881 patients were included. RESULTS: Group randomization was balanced. Travel for health care was significantly reduced in the community group exposed to the intervention during months 13 to 24 following cancer diagnosis. The mean miles traveled per patient were 1,326 (SE = 306) for the experimental group and 2,186 (SE = 347) for the control group (P = 0.03). No significant differences in satisfaction with care, economic barriers to care, or health-related quality of life were found. CONCLUSIONS: The intervention significantly reduced cancer patient travel for health care, which suggests that access to care improved in the experimental group. The results of this study do not allow conclusion that there was no effect on other patient outcomes. The results supported the study's conceptual framework and many of its hypotheses.     

Rural Health Research: Rural and Urban Physicians: Does the Content of Their Medicare Practices Differ?

Rural and urban areas have significant differences in the availability of medical technology, medical practice structures and patient populations. This study uses 1994 Medicare claims data to examine whether these differences are associated with variation in the content of practice between physicians practicing in rural and urban areas. This study compared the number of patients, outpatient visits, and inpatient visits per physician in the different specialties, diagnosis clusters, patient age and sex, and procedure frequency and type for board-certified rural and urban physicians in 12 ambulatory medical specialties. Overall, 14.4 percent of physicians in the 12 specialties practiced exclusively in rural Washington, with great variation by specialty. Rural physicians were older and less likely to be female than urban physicians. Rural physicians saw larger numbers of elderly patients and had higher volumes of outpatient visits than their urban counterparts. For all specialty groups except general surgeons and obstetrician-gynecologists, the diagnostic scope of practice was specialty-specific and similar for rural and urban physicians. Rural general surgeons had more visits for gastrointestinal disorders, while rural obstetrician-gynecologists had more visits out of their specialty domain (e.g., hypertension, diabetes) than their urban counterparts. The scope of procedures for rural and urban physicians in most specialties showed more similarities than differences. While the fund of knowledge and outpatient procedural training needed by most rural and urban practitioners to care for the elderly is similar, rural general surgeons and obstetrician-gynecologists need training outside their traditional specialty areas to optimally care for their patients.     

Orthopedic surgery in rural American hospitals: a survey of rural hospital administrators

Rural American residents prefer to receive their medical care locally. Lack of specific medical services in the local community necessitates travel to a larger center which is less favorable. This study was done to identify how rural hospitals choose to provide orthopedic surgical services to their communities. Methods: All hospitals in 5 states located in communities that met the criteria for a rural town according to the Rural Urban Commuting Area codes were included. A survey with topics including community and hospital demographics, orthopedic surgical workforce and demand, surgical services, and the perceived benefit of orthopedic services was sent to the hospital administrators. Results: Of the 223 rural hospitals surveyed, 145 completed the survey. Of those completing the survey, 30% had at least one full‐time orthopedic surgeon, 25% did not provide any orthopedic surgical services, 65% never had an orthopedic surgeon on ER call, 33% were recruiting an orthopedic surgeon, 52% stated that it is more difficult to recruit an orthopedic surgeon vs a general surgeon, and 71% of the administrators acknowledged a need for additional orthopedic surgical services in their community. For those hospitals that did not have a full‐time orthopedic surgeon, members of those communities traveled a mean distance of 55 miles for emergency orthopedic surgical care as reported by the hospital administrators. Conclusions: There are many rural communities that have limited access to orthopedic surgical services. While many of the rural hospital administrators feel that there is a need for additional orthopedic surgical services in their communities, it is difficult to recruit orthopedic surgeons to these areas.     

Abortion services in rural Washington State, 1983-1984 to 1993-1994: availability and outcomes

CONTEXT: Fewer rural health providers offer abortion services than a decade ago. It is unknown how the reduction in service availability has affected women's pregnancy outcomes, the extent to which they must travel to obtain an abortion or whether abortions are delayed as a result. METHODS: Population, birth and fetal death data, as well as pregnancy termination reports, obtained from Washington State were used to calculate abortion rates and ratios and birthrates for Washington residents in 1983-1984 and in 1993-1994. Residence of abortion patients was classified by county only, and location of providers was recorded as large urban county, small urban county, large rural county or small rural county. Distances that women traveled to obtain an abortion were calculated. Chi-square tests were used to compare urban and rural rates and ratios within time periods, and to compare changes that occurred between time periods. RESULTS: Birthrates and abortion rates decreased for both rural and urban Washington women between 1983-1984 and 1993-1994, but the magnitude of the decrease was greater for rural women. The rural abortion rate fell 27%, from 14.9 abortions per 1,000 women to 10.9 per 1,000, while the urban rate dropped 17%, from 21.8 to 18.2 per 1,000. The decline in the abortion rate was larger for adolescents than it was for other age-groups. In rural areas, the abortion rate decreased from 16.5 per 1,000 adolescents aged 10-19 in 1983-1984 to 10.8 per 1,000 in 1993-1994, while it declined from 23.3 per 1,000 to 16.9 per 1,000 in urban areas. From the earlier to the later time period, rural women traveled on average 12 miles farther each way to obtain an abortion, and the proportion who obtained the procedure in a rural county decreased from 25% to 3%. In the earlier time period, 62% of rural women traveled 50 miles or more to obtain an abortion, compared with 73% in 1993-1994. From 1983-1984 to 1993-1994, the proportion of rural women who traveled out of state for an abortion increased from 8% to 14%. The proportion of rural women terminating their pregnancy after the first trimester increased from 8% in 1983-1984 to 15% in 1993-1994. CONCLUSION: Rural Washington women are traveling farther and more often to urban and out-of-state locations for abortion services, and are obtaining their abortions at a later gestational age, which is associated with a decade-long decline in the number of abortion providers.     

Travel for Abortion Services in Alabama and Delays Obtaining Care

BackgroundIn 2013, Alabama required women seeking abortion to have a consultation visit followed by a 24-hour waiting period. These requirements may adversely affect return for timely care among those traveling long distances for services.MethodsUsing de-identified billing data from two Alabama clinics for all abortion encounters in 2013, we calculated the distance traveled from women's residential zip code and the number of days between their in-person consultation and procedure visits. To assess the associations between distance traveled and return for an abortion visit and length of interval between visits, we used logistic and ordinal logistic regression, respectively.ResultsOf the 2,730 women attending a consultation visit, 58% traveled less than 25 miles one way to the clinic, 13% traveled 25 to 49 miles, 21% traveled 50 to 100 miles, and 8% traveled more than 100 miles. Overall, 19% of women did not return to either clinic for an abortion procedure after their consultation. Distance traveled was not associated with return for an abortion visit (odds ratio, 1.04; 95% confidence interval, 0.76–1.42). Among women who returned, 59% had less than 7 days, 29% had 7 to 13 days, and 12% had 14 or more days between their consultation and procedure visits. Compared with women traveling less than 25 miles, those traveling 50 to 100 miles had significantly longer intervals between visits (odds ratio, 1.25; 95% confidence interval, 1.01–1.56).ConclusionsAlthough most women returned for their abortion procedure, many traveling long distances had a week or more between visits. Because delays may limit women's options for affordable abortion care, evidence-based policies should be adopted to facilitate women's timely receipt of services.     

Is Distance to Provider a Barrier to Care for Medicaid Patients With Breast,Colorectal, or Lung Cancer?

Purpose: Distance to provider might be an important barrier to timely diagnosis and treatment for cancer patients who qualify for Medicaid coverage. Whether driving time or driving distance is a better indicator of travel burden is also of interest. Methods: Driving distances and times from patient residence to primary care provider were calculated for 3,917 breast, colorectal (CRC) and lung cancer Medicaid patients in Washington State from 1997 to 2003 using MapQuest.com. We fitted regression models of stage at diagnosis and time‐to‐treatment (number of days between diagnosis and surgery) to test the hypothesis that travel burden is associated with timely diagnosis and treatment of cancer. Findings: Later stage at diagnosis for breast cancer Medicaid patients is associated with travel burden (OR = 1.488 per 100 driving miles, P= .037 and OR = 1.270 per driving hour, P= .016). Time‐to‐treatment after diagnosis of CRC is also associated with travel burden (14.57 days per 100 driving miles, P= .002 and 5.86 days per driving hour, P= .018). Conclusions: Although travel burden is associated with timely diagnosis and treatment for some types of cancer, we did not find evidence that driving time was, in general, better at predicting timeliness of cancer diagnosis and treatment than driving distance. More intensive efforts at early detection of breast cancer and early treatment of CRC for Medicaid patients who live in remote areas may be needed.     

Perceptions of Local Health Care Quality in 7 Rural Communities with Telemedicine

CONTEXT: Rural health services are difficult to maintain because of low patient volumes, limited numbers of providers, and unfavorable economies of scale. Rural patients may perceive poor quality in local health care, directly impacting the sustainability of local health care services. PURPOSE: This study examines perceptions of local health care quality in 7 rural, underserved communities where telemedicine was implemented. This study also assesses factors associated with travel outside of local communities for health care services. METHODS: Community-based pretelemedicine and posttelemedicine random telephone surveys were conducted in 7 northern California rural communities assessing local residents' perceptions of health care quality and the frequency of travel outside their community for health care services. Five-hundred rural residents were interviewed in each of the pretelemedicine and posttelemedicine surveys. Between surveys, telemedicine services were made available in each of the communities. FINDINGS: Residents aware of telemedicine services in their community had a significantly higher opinion of local health care quality (P =.002). Satisfaction with telemedicine was rated high by both rural providers and patients. Residents with lower opinions of local health care quality were more likely to have traveled out of their community for medical care services (P =.014). CONCLUSIONS: The introduction of telemedicine into rural communities is associated with increases in the local communities' perception of local health care quality. Therefore, is it possible that telemedicine may result in a decrease in the desire and need for local patients to travel outside of their community for health care services.     

Organization of Care for Acute Myocardial Infarction in Rural and Urban Hospitals in Kansas

CONTEXT: One in 4 Americans lives in a rural community and relies on rural hospitals and medical systems for emergent care of acute myocardial infarctions (AMI). The infrastructure and organization of AMI care in rural and urban Kansas hospitals was examined. METHODS: Using a nominal group process, key elements within hospitals that might influence quality of AMI care were identified, including personnel, equipment, organizational systems, and quality improvement activities. These elements were included in a survey of 45 rural and 12 urban Kansas hospitals. FINDINGS: Though emergency 911 systems were widely available in both urban and rural communities, paramedics and advanced cardiac life support were less likely to be available in rural communities. Few rural hospitals were capable of emergent catheterization, angioplasty, or coronary artery bypass surgery; cardiologists, though readily available by phone, were rarely available on-site. Nevertheless, most rural ambulances could not bypass local hospitals. Most rural hospitals transferred the vast majority of their patients to urban medical centers within an average distance of 78 miles. Standardized protocols were used for emergent AMI care in 67% of urban and 62% of rural hospitals. Hospitals included aspirin in 53% and beta-blockers in 28% of either protocols or standing orders. CONCLUSIONS: Although faced with more limited resources, some rural hospitals, like their urban counterparts, have implemented protocols to address emergent care of AMI patients. Nevertheless, many of these protocols omit crucial aspects of AMI care. Rural and urban hospitals should jointly develop systems that assure consistent, rapid delivery of AMI care.     

Rural‐Urban Differences in Health Services Utilization in the US‐Mexico Border Region

Purpose: Evaluate the association between driving distance to the US‐Mexico border and rural‐urban differences in the use of health services in Mexico by US border residents from Texas. Methods: Data for this study come from the Cross‐Border Utilization of Health Care Survey, a population‐based telephone survey conducted in the Texas border region in spring 2008. Driving distances to the border were estimated from the nearest border crossing station using Google Maps. Outcome measures included medication purchases, physician visits, dentist visits, and inpatient care in Mexico during the 12 months prior to the survey. A series of adjusted logit models were estimated after controlling for relevant confounding factors. Findings: The average driving distance to the nearest border crossing station among rural respondents was 4 times that of urban respondents (42.0 miles vs 10.3 miles [P < .001]). Rural respondents were more likely to be dissatisfied than urban respondents with the health care provided on the US side of the border, yet they were less likely to use health services in Mexico. Driving distance to the border largely explained the observed rural‐urban differences in medication purchases from Mexico. In the case of inpatient care, however, rural respondents reported a higher utilization rate than urban respondents and this rural‐urban difference became more pronounced after adjusting for the effect of driving distance to the border. Conclusions: Dissatisfaction with US health care services in rural communities in the US‐Mexico border region seems to be compounded by the lack of access to health care services in Mexico due to travel distance constraints.     

Defining “Rural” for Veterans’ Health Care Planning

Purpose: The Veterans Health Administration (VHA) devised an algorithm to classify veterans as Urban, Rural, or Highly Rural residents. To understand the policy implications of the VHA scheme, we compared its categories to 3 Office of Management and Budget (OMB) and 4 Rural-Urban Commuting Area (RUCA) geographical categories. Method: Using residence information for VHA health care enrollees, we compared urban-rural classifications under the VHA, OMB, and RUCA schemes; the distributions of rural enrollees across VHA health care networks (Veterans Integrated Service Networks [VISNs]); and how each scheme indicates whether VHA standards for travel time to care are met for the most rural veterans. Results: VHA's Highly Rural and Urban categories are much smaller than the most rural or most urban categories in the other schemes, while its Rural category is much larger than their intermediate categories. Most Highly Rural veterans live in VISNs serving the Rocky Mountains and Alaska. Veterans defined as the most rural by RUCA or OMB are distributed more evenly across most VISNs. Nearly all urban enrollees live within VHA standards for travel time to access VHA care; so do most enrollees defined by RUCA or OMB as the most rural. Only half of Highly Rural enrollees, however, live within an hour of primary care, and 70% must travel more than 2 hours to acute care or 4 hours to tertiary care. Conclusions: VHA's Rural category is very large and broadly dispersed; policy makers should supplement analyses of Rural veterans’ health care needs with more detailed breakdowns. Most of VHA's Highly Rural enrollees live in the western United States where distances to care are great and alternative delivery systems may be needed.     

Distance, Use of Resources, and Mortality Among Rural Missouri Residents With Acute Myocardial Infarction

Abstract: Prompt access to medical services is considered critical in managing acute myocardial infarction (AMI). Several socioeconomic and geographic factors affect access to such care in rural areas. This study measured the effect of geographic distance from care on utilization of cardiovascular technology and death after AMI. The records of 1,658 rural Missouri residents age 65 or older with a discharge diagnosis of AMI in 1991 were obtained from Medicare data. The rate of use of cardiovascular technology and rate of post-AMI mortality for rural Missouri residents who live far from emergency departments and cardiac referral centers (CRC) were compared with those who live nearest such services. Those living 60 miles or more from a CRC were less likely to have cardiac catheterization (odds ratio [OR]=0.55; 95% confidence interval [CI]=0.40 to 0.75) or angioplasty (OR=0.68; 95% CI=0.47 to 0.98), compared with those living fewer than 30 miles from a CRC. There were no differences in 30-day, 90-day, or one-year mortality rates. After adjusting for distance to a CRC, those living 20 miles or more from emergency services were more likely to have coronary artery bypass grafting (OR=1.92; 95% CI=1.18 to 3.15) than those living fewer than 10 miles from such services, but there was no difference in mortality. Distance from services strongly predicts utilization of cardiovascular resources, but it does not predict mortality among rural Missouri Medicare beneficiaries hospitalized with AMI.     

Illness severity and propensity to travel along the urban-rural continuum

In this paper, we examine whether the relationship between severity of illness and the propensity to travel greater distance relative to the norm (defined by peers in one's county of residence) is uniform across the urban-rural continuum of geography or over time. We focus on the elderly in New York State who have been admitted to hospital for ambulatory care sensitive conditions (ACSCs), admissions which are presumed to be representative of usual travel patterns. The two periods of time examined span the implementation of the Balanced Budget Act (BBA) of 1997, which established the Medicare Rural Hospital Flexibility Program, a major national initiative to strengthen rural health care with the development of rural Critical Access Hospitals (CAHs). As the number of NY rural hospitals certified as CAH increased with the expanded funding from the BBA, one might expect to see increased distance traveled by more severely ill rural elderly, as their CAHs referred them to their affiliated support hospitals. The logistic regression estimates support this expectation, highlighting an asymmetrical relationship between relative distance and severity across patients in rural and urban areas. Despite a general decline in average propensity to travel further than the norm across the landscape, severity had a larger impact on travel propensity in rural areas, which increased over time.     

A rural/urban comparison of the roles of the general practitioner in colorectal cancer management

Objective: To identify and compare the roles of urban, rural and remote general practitioners (GPs) in colorectal cancer (CRC) management. Design: Semistructured interviews exploring GP views of their role in CRC management. Setting: Urban, rural and remote general practices in north Queensland. Participants: Fifteen GPs in urban, rural and remote practice. Main outcome measures: Self‐reported roles in the management of CRC patients and factors influencing these roles. Results: All GPs, regardless of location of practice, played a role in diagnosis, referral, postoperative care, psychosocial counselling, follow up and palliative care. Involvement in treatment of CRC patients was only performed by remote GPs. In general, rural and remote GPs played greater roles in care coordination, clinical and psychosocial care. Rural and remote GPs were more heavily involved throughout the entire illness progression when compared with their urban counterparts. Conclusions: The results of this study indicate that rural and remote GPs in north Queensland play a greater role than urban GPs in the management of CRC. In order to maintain and enhance the roles of rural and remote GPs in CRC care, appropriate guidelines and remuneration should be provided. Palliative care support might also be useful to rural and remote GPs.     

Influence of Place of Residence in Access to Specialized Cancer Care for African Americans

Context: Disparities in cancer care for rural residents and for African Americans have been documented, but the interaction of these factors is not well understood.
Purpose: The authors examined the simultaneous influence of race and place of residence on access to and utilization of specialized cancer care in the United States.
Methods: Access to specialized cancer care was measured using: (1) travel time to National Cancer Institute (NCI) Cancer Centers, academic medical centers, and any oncologist for the entire continental US population, and (2) per capita availability of oncologists for the entire United States. Utilization was measured as attendance at NCI Cancer Centers, specialized hospitals, and other hospitals in the Surveillance, Epidemiology, and End Results (SEER) program Medicare population from 1998-2004.
Findings: In urban settings, travel times were shorter for African Americans compared with Caucasians for all three cancer care settings, but they were longer for rural African Americans traveling to NCI Cancer Centers. Per capita oncologist availability was not significantly different by race or place of residence. Urban African American patients were almost 70% more likely to attend an NCI Cancer Center than urban Caucasian patients (OR = 1.66; 95% CI 1.51-1.83), whereas rural African American patients were 58% less likely to attend an NCI Cancer Center than rural Caucasian patients (OR = 0.42; 95% CI 0.26-0.66).
Conclusions: Urban African Americans have similar or better access to specialized cancer care than urban Caucasians, but rural African Americans have relatively poor access and lower utilization compared with all other groups.     

Self‐Reported Cancer Screening Among Elderly Medicare Beneficiaries: A Rural‐Urban Comparison

Purpose: We examined the rural‐urban disparity of screening for breast cancer and colorectal cancer (CRC) among the elder Medicare beneficiaries and assessed rurality's independent impact on receipt of screening. Methods: Using 2005 Medicare Current Beneficiary Survey, we applied weighted logistic regression to estimate the overall rural‐urban disparity and rurality's independent impact on cancer screening, controlling for patient, and area factors. Results: From urban, large rural, small rural, and isolated rural areas, the rates for mammogram last year were 53%, 52%, 45%, and 44%, respectively. They were 56%, 50%, 48%, and 43% for CRC screening, respectively. After controlling for patient and area level characteristics, rurality is significantly associated with CRC screening, but not mammogram. Conclusions: We found rural‐urban disparities for both mammogram and CRC screenings. Patient and area factors totally eliminated the rural‐urban disparity for mammogram but not CRC screening. Health promotions to improve cancer screening should focus more on small and isolated rural areas.     

Patterns of travel for rural individuals hospitalized in New York State: relationships between distance, destination, and case mix.

The travel patterns of individuals living in rural areas of New York State who were discharged from short-term general hospitals in New York State in 1983 are examined. Counties are used as the geographical unit, and rural individuals who cross geographic boundaries to obtain inpatient hospital care are compared with those who receive such care in their own geographic area. Hospital serving the rural population of New York are classified into three types: urban, consisting of all hospitals located in MSAs; rural referral centers; and other rural hospitals. Next, the rural patients who are admitted to each of these three types of hospitals are characterized in terms of distance traveled, case mix, length of stay, and age. Individuals who travel beyond the counties adjacent to their county of residence had a higher case mix index but were less likely to be more than 75 years old. Distance traveled and the expected cost of care were strongly positively related for patients admitted to urban and rural referral center hospitals, but were only weakly related for other rural hospitals. Finally, comparisons of rural patients in these three types of hospitals were performed adjusting for DRG mix, a comparison which is relevant to hospital reimbursements under the Medicare Prospective Payment System. Using several measures of illness severity, rural patients in urban hospitals and rural referral center hospitals were more severely ill than rural patients in other rural hospitals after adjusting for DRG mix. We conclude that somewhat higher payments to urban hospitals and rural referral center hospitals in New York are justified based on the more severely ill patients which they treat     

Accessibility and utilization patterns of a mobile medical clinic among vulnerable populations

We mapped mobile medical clinic (MMC) clients for spatial distribution of their self-reported locations and travel behaviors to better understand health-seeking and utilization patterns of medically vulnerable populations in Connecticut. Contrary to distance decay literature, we found that a small but significant proportion of clients was traveling substantial distances to receive repeat care at the MMC. Of 8404 total clients, 90.2% lived within 5 miles of a MMC site, yet mean utilization was highest (5.3 visits per client) among those living 11–20 miles of MMCs, primarily for those with substance use disorders. Of clients making >20 visits, 15.0% traveled >10 miles, suggesting that a significant minority of clients traveled to MMC sites because of their need-specific healthcare services, which are not only free but available at an acceptable and accommodating environment. The findings of this study contribute to the important research on healthcare utilization among vulnerable population by focusing on broader dimensions of accessibility in a setting where both mobile and fixed healthcare services coexist.
