Geographic variations in physician service utilization

Expanding research on the racial disparity in medical treatment with ideas from sociology

While hundreds of studies document racial differences in the use of medical procedures in the United States, by comparison little is known about the causes of these differences. This gap in knowledge should serve as a call to sociologists who, drawing on their disciplinary tradition of studying inequality, could improve understanding of the disparity. This article offers suggestions about how medical sociologists in the USA might bring sociology to the study of racial disparities in medical treatment. The article begins by reviewing the existing approaches to understanding the racial disparity in medical treatment. After considering the extant research and its limits, the article goes on to describe how a few specific concepts from sociology - cultural capital, social networks, self-presentation and social distance, all framed in a race critical framework - and more diverse methodological approaches can advance studies of the racial disparity in medical treatment

The Assessment of Inequality in the Geographical Distribution of Burn Beds in Iran

INTRODUCTION

In recent years, the World Health Organization (WHO) has emphasized the importance of determining the equality of the distribution of healthcare resources. Inequalities in the healthcare system are one of the world's most important developmental challenges, and the inefficiencies that exist in healthcare systems are the most important reason for these challenges. Thermal burns are one of the common injuries worldwide, and their effects are a significant reason for the mortality and morbidity rates throughout the world. Considering the importance of burns as one of the 30 leading causes of death in Iran, this study was aimed to compare the distribution of burn beds with its disability-adjusted life years (DALY) in Iran.

METHODS

This applied analytic-descriptive study was conducted in order to determine the distribution of burn beds in Iran using the Lorenz curve. In this way, the distribution of burn beds was analyzed in relation to the population of each province and lost DALY caused by burns in Iran. For each province, the number of burn beds in 2012 was collected from credible and authoritative sources at the Ministry of Health, and the population of each province was obtained using data from the National Center of Statistics. The data were analyzed and presented using Microsoft Office Excel.

RESULTS

Isfahan and Khorasan Razavi Provinces had approximately 11 and 10.4% of the country's burn beds, respectively. The Provinces that had the most DALY were Sistan Baluchestan, Fars, and Kerman with 10.75%, 10.34%, and 9.54%, respectively. The Gini coefficients of burn beds in relation to population and DALY were calculated as 0.09 and 0.16, respectively.

CONCLUSION

The Gini coefficients in relation to population and DALY were less than 0.2. Although the Gini coefficient of the burn beds in relation to DALY was more than that for the population, the difference was not significant, and the distributions of beds regarding the two calculated coefficients were equal. It is recommended that healthcare policymakers distribute burn beds in proportion to the populations of the provinces.

A comparison of future recruitment needs in urban and rural hospitals: the rural imperative

BACKGROUND

The potential impact of shortages of the surgical workforce on both urban and rural hospitals is undefined. There is a predicted shortage of 30,000 surgeons by 2030 and the need to train and hire more than 100,000 surgeons. The aim of this study is to estimate the average recruitment needs in our nation's hospitals for 7 surgical specialties to ensure adequate access to surgical care as the U.S. population grows to 364 million by 2030.

METHODS

We used the census figure of 309 million in 2010 for U.S. population. Currently there are estimated to be 3,012 urban hospitals and 1,998 rural hospitals in the U.S. (American Hospital Association's Trend Watch report, 2009). At 253 million people (82 % of the population of 309 million in 2010) receive healthcare in urban hospitals; 56 million people receive healthcare in rural hospitals (18%). We assumed a work force model based on our previous publications, equal population growth in all geographic areas, recruitment by rural hospitals limited to Ob-Gyn, General Surgery, and Orthopedics, and that the percentage of the population receiving care at urban and rural hospitals will stay constant.

RESULTS

Rural hospitals will have to recruit an average of 3.4 OBGYN's, and an average of 1.6 Orthos, and 2.0 GS for a total of 7 full-time equivalents in the period from 2011 to 2030. Urban hospitals which have to recruit surgical specialists will have to recruit ten Ob-Gyns, about 5 Orthos, 6 GS's, 5 ear, nose, and throat surgeons (ENT's), an average of 2.5 urologists, a neurosurgeon, and a thoracic surgeon to meet the recruiting goals for the surgical services for their hospitals.

CONCLUSION

Rural hospitals will be in competition with urban hospitals for hiring from a limited pool of surgeons. As urban hospitals have a socioeconomic advantage in hiring, surgical care in rural areas may be at risk. It is imperative that each rural hospital analyze local future healthcare needs and devise strategies that will enhance hiring and retention to optimize access to surgical care.

The role of human papillomavirus vaccination in promoting delivery of other preventive and medical services

OBJECTIVE

Adolescents infrequently present for preventive health visits. The 3-dose human papillomavirus (HPV) vaccine may result in increased health care visits and thus indirectly improve health services for teens. We examined whether other health services were delivered in conjunction with the second (HPV2) or third (HPV3) dose of the HPV vaccine.

METHODS

We conducted a chart review for girls 9 to 20 years of age (n = 571) who received HPV2 or HPV3 within 4 months of its due date at any of 9 clinical sites. Analyses were limited to the 422 visits (72%) where HPV vaccine was specified as a reason for the visit. A generalized linear model was used to evaluate the impact of site of care on delivery of other health services.

RESULTS

Nearly half (43%) of adolescents received another medical or preventive health service at the time of HPV2 or HPV3 vaccine administration. Most common services were 1 or more other vaccines (30%) or medical services (35%). Older teens were more likely than younger teens to receive reproductive health services and sexually transmitted infection screening. After controlling for age and adjusting for clustering within sites, receiving care at an academic health center versus a private practice was strongly associated with increased odds of receiving other medical or preventive health services at follow-up (odds ratio 2.07; 95% confidence interval 1.44-2.97).

CONCLUSIONS

Adolescents, especially those receiving care at an academic health center, often received other health services at the time of HPV2 or HPV3 vaccination. Because visits occurred within 6 to 8 months of the prior vaccine dose, our findings suggest vaccine visits may lead to improved delivery of adolescent health services.

Utilization of Medical Services at the End of Life in Older Adults with Cognitive Impairment: Focus on Outliers

BACKGROUND

The use of intensive medical care near end of life is often questioned because of potential burden to patients, their families, and society. Efforts to moderate intensive end-of-life care may be facilitated by early identification of those at greatest risk for receiving such care.

OBJECTIVE

To examine factors associated with intensive end-of-life medical care utilization in nursing home residents with severe cognitive impairment.

DESIGN

Retrospective review of existing Medicare data: 1998-2001 Minimum Data Set (MDS), Medicare Denominator, MedPAR, and hospice files.

METHODS

Subjects were Minnesota and Texas nursing home residents from rural and urban counties (USDA metro-nonmetro continuum codes: 0-2 urban, 6-9 rural), who had severe cognitive impairment and who died during 2000-2001. Hospice and managed care enrollees were excluded. High medical care users were defined as subjects with 7+ intensive care unit (ICU) days in the last 90 days of life. Measures of end-of-life medical care utilization intensity included tube feeding on the last MDS report, number of hospital and ICU days, and total hospital charges during the study period.

RESULTS

The study population included 1494 nursing home residents who were hospitalized within 90 days prior to death; 82 (5%) met the high medical care user criteria. In multivariable analysis: urban location (p < 0.001), lack of do-not-resuscitate directive (p = 0.002), non-white race (p = 0.021), and having 3+ comorbidities (p = 0.021) were independently associated with high medical care utilization.

CONCLUSIONS

Urban nursing home location and lack of do-not-resuscitate directives were the strongest predictors of high medical care utilization near the end of life.

Threats to rural surgery

BACKGROUND

Rural surgery is a subject that often is discussed but little has been done to address the problems of rural surgery. With a decreased interest in broad-based general surgery, an aging population (especially in rural America), an aging population of general surgeons who are retiring early, surgical care in rural North America is approaching a crisis.

METHODS

An internet search was performed to analyze the problems in rural surgery. Also, the experience of a 90-bed rural hospital in south central Kentucky was analyzed.

RESULTS

Approximately 17% to 25% of the population in America (55 million) live in a rural environment, depending on the way rural is defined. Rural general surgeons may become an endangered species because of multiple factors, including: lack of broad-based training, increased specialization, lifestyle issues, decreased interest in surgery, increased technology, aging rural surgeons, increased workload for the general surgeon, decreased reimbursement, increased expenses, increased expectations of the general public, and increased malpractice costs. Solutions include programs dedicated to training rural surgeons, networking with university tertiary care hospitals, equal pay for work performed regardless of the location, regionalization of rural surgery centers with multiple surgeons so the lifestyle issues can be addressed.

CONCLUSIONS

There is an increasing need for broad-based general surgeons in rural America. Training programs need to address the problem by offering dedicated training programs that should include primary training in general surgery and fellowships for special needs. A new specialty in rural general surgery needs to be created.

Trends in geographic disparities in allocation of health care resources in the US

OBJECTIVES

This study aimed to examine current level and historical trends in health resources distribution in the US; to investigate the relationships between both levels and trends of inequality with--geographic location, inequality of income and rates per capita of hospital-beds and physicians.

METHODS

The Gini Coefficient was used to measure variations in distribution of physicians and hospital-beds (at the county level) during three decades.

RESULTS

Physician distribution has become less equitable, while hospital-beds' equity has increased. physicians' distribution exhibited a geographic trend, becoming more equitable in the West. No association was found between equality in hospital-beds' distribution and rates of hospital-beds per capita.

CONCLUSIONS

Rates per capita might not be sufficient in determining availability of resources. Further research is needed to determine implications for health outcomes.

Access to care for rural Medicare beneficiaries

This paper examines variations between urban and rural Medicare beneficiaries in three measures of access to care: self-reported access to care, satisfaction with care received and use of services. The assessment focuses on these measures and their relationship to adjacency to metropolitan areas. Comparisons are also provided for the relative effects of adjacency versus broader access barriers such as income. Data from the 1993 Medicare Current Beneficiary Survey are used. The analyses offer several new perspectives on access in rural areas. First, as perceived by respondents, rural residence does not indicate access problems; instead, Medicare beneficiaries in rural counties that are adjacent to urban areas and that have their own city of at least 10,000 people report higher levels of satisfaction and fewer self-reported access problems than do residents of urban counties. These results may stem either from differences in rural residents' expectations regarding access or willingness to accept appropriate substitutions. Preventive vaccination rates in rural areas are on par with or better than rates by beneficiaries in urban areas. The only services where utilization in rural areas was limited relative to urban areas were preventive cancer screening for women and dental care. Development of policies to address these specific service gaps may be warranted. Low income has a more pervasive and problematic relationship to self-reported access, satisfaction and utilization than does rural residence per se.

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.

Substance abuse as a predictor of VA medical care utilization among Vietnam veterans

The primary objective was to determine whether Vietnam veterans who had alcohol or drug use problems prior to, during, or immediately after the war used Veterans Administration (VA) health care services more intensively during the next two decades than Vietnam veterans without these behaviors. The secondary objective was to identify predictors of VA health services utilization among data collected at service discharge. Logistic and ordinary least squares regression were used to model the effect of predisposing, enabling, and need factors on utilization of VA health services (N = 571). Results show that Vietnam veterans who had substance use problems either before or immediately after Vietnam used VA health care services more intensively during the next two decades than Vietnam veterans without these behaviors. Depression and psychiatric care seeking were also important predictors. More research is needed to evaluate the impact of health system characteristics and private sector use on the predictive ability of the models.

Hemodialysis adequacy in Network 5: disparity between states and the role of center effects

The purpose of this study was to determine whether an observed difference in hemodialysis adequacy between states in Network 5 was due to variations in patient characteristics and to what extent dialysis center effects played a role in the observed disparity between states. This was a retrospective observational study of 6,969 patients dialyzed at centers in Maryland and Virginia. There were 3,919 patients on hemodialysis at 89 facilities in Virginia and 3,050 subjects dialyzed at 65 centers in Maryland. The mean urea reduction ratio (URR) was higher in Virginia compared with Maryland (68.2 +/- 0.1% v 66.0 +/- 0.2%, P < 0.0001, respectively), and there continued to be a mean difference in URR of 1.8% between VA and MD (P < 0.0001) after adjusting for several covariates. The differences in URR between states varied depending on facility proprietary status, size as measured by number of stations, and relationship to hospital (free-standing or hospital-based). Furthermore, the center where a patient dialyzed, when treated as a fixed effect, accounted for 15% of the variance in URR. The mean difference of 1.8% in URR between states persisted in a mixed-effects model that included all covariates along with adjusting for dialysis centers as a random effect. The disparity in dialysis adequacy between states in Network 5 could not be accounted for by demographic characteristics, case mix factors, or a large center effect observed in the region. Therefore, we conclude that underlying national reports on dialysis adequacy are heterogeneous results related to differences across regions such as states within a given Network. This difference between states is not explained by the strong center effect found on adequacy in this population of hemodialysis patients.

Rates of dental service provision between capital city and non-capital locations in Australian private general practice

Variations in service provision between geographical locations may be associated with factors such as imbalances in the availability of health services. The aim of this analysis was to examine differences in dental service provision between capital city and non-capital locations. Data were used from a survey collected in 1993/94 from a random sample of Australian dentists, providing 817 responses (a response rate of 74%). Dentists from capital city locations comprised 71.8% of responding private general practitioners. Significantly more services per visit (Mann-Whitney, P < 0.05) were provided at capital city locations (mean = 2.16, 95% CI = 2.08-2.24) compared to non-capital locations (mean = 1.84, 95% CI = 1.74-1.94). Controlling for age of patient, insurance status and visit type, capital city locations included significantly higher rates of service per visit (P < 0.05) for adult dentate patients (rate ratios, 95% CI) of diagnostic (1.17, 1.09-1.25), preventive (1.20, 1.09-1.32), periodontal (2.71, 1.72-4.26), and crown and bridge (1.25, 1.03-1.53) services, but lower rates of prosthodontic (0.80, 0.67-0.94) services compared to non-capital locations. These findings indicate that compared to non-capital locations, capital city patients received care that was more orientated towards prevention and maintenance of teeth, rather than replacement by dentures.
