Racial, ethnic, and rural disparities in distance to physicians among decedents with Alzheimer's disease and related dementias in Washington State.

INTRODUCTION: Distance to physicians may explain some of the disparities in Alzheimer's disease and related dementia (AD/ADRD) outcomes. METHODS: We generated round trip distance between residences of decedents with AD/ADRD and the nearest neurologist and primary care physician in Washington State. RESULTS: The overall mean distance to the nearest neurologist and primary care physician was 17 and 4 miles, respectively. Non-Hispanic American Indian and/or Alaska Native and Hispanic decedents would have had to travel 1.12 and 1.07 times farther, respectively, to reach the nearest neurologist compared to non-Hispanic White people. Decedents in micropolitan, small town, and rural areas would have had to travel 2.12 to 4.01 times farther to reach the nearest neurologist and 1.14 to 3.32 times farther to reach the nearest primary care physician than those in metropolitan areas. DISCUSSION: These results underscore the critical need to identify strategies to improve access to specialists and primary care physicians to improve AD/ADRD outcomes. HIGHLIGHTS: Distance to neurologists and primary care physicians among decedents with AD/ADRD American Indian and/or Alaska Native decedents lived further away from neurologists Hispanic decedents lived further away from neurologists Non-metropolitan decedents lived further away from neurologists and primary care Decrease distance to physicians to improve dementia outcomes.

Doctor retention and distribution in post-apartheid South Africa: tracking medical graduates (2007-2011) from one university.

BACKGROUND: Doctor emigration from low- and middle-income countries represents a financial loss and threatens the equitable delivery of healthcare. In response to government imperatives to produce more health professionals to meet the country's needs, South African medical schools increased their student intake and changed their selection criteria, but little is known about the impact of these changes. This paper reports on the retention and distribution of doctors who graduated from the University of the Witwatersrand, South Africa (SA), between 2007 and 2011. METHODS: Data on 988 graduates were accessed from university databases. A cross-sectional descriptive email survey was used to gather information about graduates' demographics, work histories, and current work settings. Frequency and proportion counts and multiple logistic regressions of predictors of working in a rural area were conducted. Open-ended data were analysed using content analysis. RESULTS: The survey response rate was 51.8%. Foreign nationals were excluded from the analysis because of restrictions on them working in SA. Of 497 South African respondents, 60% had completed their vocational training in underserved areas. At the time of the study, 89% (444) worked as doctors in SA, 6.8% (34) practised medicine outside the country, and 3.8% (19) no longer practised medicine. Eighty percent of the 444 doctors still in SA worked in the public sector. Only 33 respondents (6.6%) worked in rural areas, of which 20 (60.6%) were Black. Almost half (47.7%) of the 497 doctors still in SA were in specialist training appointments. CONCLUSIONS: Most of the graduates were still in the country, with an overwhelmingly urban and public sector bias to their distribution. Most doctors in the public sector were still in specialist training at the time of the study and may move to the private sector or leave the country. Black graduates, who were preferentially selected in this graduate cohort, constituted the majority of the doctors practising in rural areas. The study confirms the importance of selecting students with rural backgrounds to provide doctors for underserved areas. The study provides a baseline for future tracking studies to inform the training of doctors for underserved areas.

Inequality of obstetric and gynaecological workforce distribution in China.

BACKGROUND: Women's health is defined as a continuum throughout their whole lives. In China, women receive life-round preventative and curative health care from the health system, although the universal access to reproductive health has already been basically achieved in China, the situation of women's access to curative health care is still unknown. METHODS: Data from the national maternal and child health human resource investigation were analysed. Lorenz curves, Gini coefficients, and Theil L indexes were drawn and calculated to reflect the inequality. Demographically, we found that the Obstetric and gynaecological (OB/GYN) workforce was the least equitable regarding the distribution of live births. RESULTS: Demographically, we found that the OB/GYN workforce was the least equitable regarding the distribution of live births. The geographic distribution of the OB/GYN workforce was found to be severely inequitable, especially in the West region. Most of the inequality was found to come from inner-regions. CONCLUSION: For the first time, the distribution inequality of OB/GYN workforce in China was analysed. The findings in this study can be adopted in making national or regional OB/GYN workforce allocation policies, but further studies are still needed to reveal the detailed sources of inequality and to provide evidence for local policy-making.

State Medicaid fees and access to primary care physicians.

Medicaid and uninsured patients are disadvantaged in access to care and are disproportionately Black and Hispanic. Using a national audit of primary care physicians, we examine the relationship between state Medicaid fees for primary care services and access for Medicaid, Medicare, uninsured, and privately insured patients who differ by race/ethnicity and sex. We found that states with higher Medicaid fees had higher probabilities of appointment offers and shorter wait times for Medicaid patients, and lower probabilities of appointment offers and longer wait times for uninsured patients. Appointment offers and wait times for Medicare and privately insured patients were unaffected by Medicaid fees. At mean state Medicaid fees, our analysis predicts a 27-percentage-point disadvantage for Medicaid versus Medicare in appointment offers. This decreases to 6 percentage points when Medicaid and Medicare fees are equal, suggesting that permanent fee parity with Medicare could eliminate most of the disparity in appointment offers for Medicaid patients. The predicted decrease in the disparity is smaller for Black and Hispanic patients than for White patients. Our research highlights the importance of considering the effects of policy on nontarget patient groups, and the consequences of seemingly race-neutral policies on racial/ethnic and sex-based disparities.

A community-based strategy in medical education of the university of the philippines manila-school of health sciences - Lessons from innovations in human resources for health development in a developing country.

Background: After nearly four decades of testing an innovative model for training health workers for marginalized communities, the evidence base for the impact of University of the Philippines Manila-School of Health Sciences (UPM-SHS) medical program needs to address important gaps. Has it succeeded in contributing toward socially accountable medical education where medical schools will be evaluated in terms of their contribution to society's health outcomes? To answer this question, this study examined human resources for health (HRH) inequity in the Philippines and reviewed the medical school's performance in terms of addressing HRH distribution. Methods: The evaluation of the school's performance was done through two phases. Phase 1 involved generating HRH inequity metrics for the Philippines through secondary data. Phase 2 involved gathering primary data and generating performance metrics for UPM-SHS. Results: We found challenges that UPM-SHS needs to address based on the analysis of its student admissions from 1976 to 2011: targeting the right underserved communities, especially at the municipal level; addressing issues of high leakage and undercoverage rates in the program; ensuring mechanisms for return service are in place at the community level; and tracking and measuring program outputs and impact on community health outcomes. Discussion: Given this study on the performance of UPM-SHS to produce a broad range of health workforce to address the needs of marginalized communities in the Philippines and in similarly situated countries, there is a need to reassess its HRH development strategy. If it wants to build a critical mass of transformational health leaders to meet the needs of poor communities as part of its social accountability mandate, it needs to accelerate this development process.

Distribution of health care resources in Mongolia using the Gini coefficient.

BACKGROUND: Attaining the perfect balance of health care resources is probably impracticable; however, it is possible to achieve improvements in the distribution of these resources. In terms of the distribution of health resources, equal access to these resources would make health services available to all people. The aim of this study was to compare the distributions of health care resources in urban, suburban, and rural areas of Mongolia. METHODS: We compared urban and rural areas using the Mann-Whitney U test and further investigated the distribution equality of physicians, nurses, and hospital beds throughout Mongolia using the Gini coefficient-a common measure of distribution derived from the Lorenz curve. Two indicators were calculated: the distribution per 10 000 population and the distribution per 1000 km2 area. RESULTS: Urban and rural areas were significantly different only in the distribution of physicians per population. However, in terms of the distribution per area, there were statistical differences in physicians, nurses, and hospital beds. We also found that distributions per population unit were equal, with Gini coefficients for physicians, nurses, and hospital beds of 0.18, 0.07, and 0.06, respectively. Distributions per area unit were highly unequal, with Gini coefficients for physicians, nurses, and hospital beds of 0.74, 0.67, and 0.69, respectively. CONCLUSIONS: Although the distributions of health care resources per population were adequate for the population size, a striking difference was found in terms of the distributions per geographical area. Because of the nomadic lifestyle of rural and remote populations in Mongolia, geographical imbalances need to be taken into consideration when formulating policy, rather than simply increasing the number of health care resources.

Rural Health Care Access and Policy in Developing Countries.

Compared to their urban counterparts, rural and remote inhabitants experience lower life expectancy and poorer health status. Nowhere is the worldwide shortage of health professionals more pronounced than in rural areas of developing countries. Sub-Saharan Africa (SSA) includes a disproportionately large number of developing countries; therefore, this article explores SSA in depth as an example. Using the conceptual framework of access to primary health care, sustainable rural health service models, rural health workforce supply, and policy implications, this article presents a review of the academic and gray literature as the basis for recommendations designed to achieve greater health equity. An alternative international standard for health professional education is recommended. Decision makers should draw upon the expertise of communities to identify community-specific health priorities and should build capacity to enable the recruitment and training of local students from underserviced areas to deliver quality health care in rural community settings.

Trends in geographic distribution of nursing staff in Japan from 2000 to 2010: a multilevel analysis.

The aim of this study was to examine trends in the geographic distribution of nursing staff in Japan from 2000 to 2010. We examined time trends in the rates of nursing staff per 100,000 population across 349 secondary health service areas. Using the Gini coefficient as a measure of inequality, we separately analyzed the data of 4 nursing staff types:public health nurses (PHN), midwives (MW), nurses (NS), and associate nurses (AN). Then, using multilevel Poisson regression models, we calculated the rate ratios (RRs) and their 95% confidence intervals (CIs) for each type of nursing staff per 1-year change. Overall, the distribution of PHN, MW, and NS improved slightly in terms of the Gini coefficient. After adjusting for prefectural capital and population density, PHN, MW, and NS significantly increased;the RRs per 1-year increment were 1.022 (95% CI:1.020-1.023), 1.021 (95% CI:1.019-1.022), and 1.037 (95% CI:1.037-1.038), respectively. In contrast, AN significantly decreased;the RR per 1-year increment was 0.993 (95% CI:0.993-0.994). Despite the considerable increase in the absolute number of nursing staff in Japan (excluding AN), this increase did not lead to a sufficient improvement in distribution over the last decade.

[Inequality and inequity in the use of medical services in Chile, by age group, 2000-2011]. / Desigualdad e inequidad en la utilización de servicios médicos según grupos etarios en Chile, 2000-2011.

OBJECTIVE: To calculate indices of inequality and inequity in the use of medical services for children, adults, and older adults in Chile from 2000 to 2011. METHODS: Based on the CASEN survey (2000-2011), the concentration index (CI) was calculated to measure inequality and the horizontal inequity index (HI) was calculated to measure inequity in the use of medical services. Four groups were studied: children under 5, children aged 6-18 years, adults, and older adults. RESULTS: The results indicate higher levels of inequality in the use of specialized physician services in the child groups, and higher levels of inequity in the adult group. In the use of dental services, the greatest inequality and inequity is found among older adults. For visits to emergency services in the last two years for which data are available (2009 and 2011), the adult group shows a higher level of inequality. CONCUSIONS: In terms of levels of inequity and inequality, there are differences among children, adults, and older adults over the years in at least three of the six variables studied.

An Analysis of Trainee Status of the Primary Care Physician and Ambulatory Care Outcomes.

PURPOSE: Prior studies report disparities in outcomes for patients cared for by trainees versus faculty physicians at academic medical centers. This study examined the effect of having a trainee as the primary care physician versus a faculty member on routine population health outcomes after adjusting for differences in social determinants of health and primary care retention. METHOD: This cohort study assessed 38,404 patients receiving primary care at an academic hospital-affiliated practice by 60 faculty and 110 internal medicine trainees during academic year 2019. The effect of primary care practitioner trainee status on routine ambulatory care metrics was modeled using log-binomial regression with generalized estimating equation methods to account for physician-level clustering. Risk estimates before and after adjusting for social determinants of health and loss to follow-up are presented. RESULTS: Trainee and faculty cohorts had similar distributions of acute illness burden; however, patients in the trainee cohort were significantly more likely to identify as a race other than White (2,476 [52.6%] vs 14,785 [38.5%], P < .001), live in a zip code associated with poverty (1,688 [35.9%] vs 9,122 [23.8%], P < .001), use public health insurance (1,021 [21.7%] vs 6,108 [15.9%], P < .001), and have limited English proficiency (1,415 [30.1%] vs 5,203 [13.6%], P < .001). In adjusted analyses, trainee status of primary care physician was not associated with lack of breast cancer screening but was associated with missed opportunities to screen for colorectal cancer (relative risk [RR], 0.77; 95% confidence interval [CI], 0.68-0.88), control type 2 diabetes mellitus (RR, 0.78; 95% CI, 0.64-0.94), and control hypertension (RR, 0.80; 95% CI, 0.69-0.94). CONCLUSIONS: Primary care physician trainee status was associated with poorer quality of care in the ambulatory setting after adjusting for differences in socioeconomic factors and loss to follow-up, highlighting a potential ambulatory training gap.

Geographic Disparities in Potential Accessibility to Gynecologic Oncologists in the United States From 2001 to 2020.

OBJECTIVE: To use a spatial modeling approach to capture potential disparities of gynecologic oncologist accessibility in the United States at the county level between 2001 and 2020. METHODS: Physician registries identified the 2001-2020 gynecologic oncology workforce and were aggregated to each county. The at-risk cohort (women aged 18 years or older) was stratified by race and ethnicity and rurality demographics. We computed the distance from at-risk women to physicians. Relative access scores were computed by a spatial model for each contiguous county. Access scores were compared across urban or rural status and racial and ethnic groups. RESULTS: Between 2001 and 2020, the gynecologic oncologist workforce increased. By 2020, there were 1,178 active physicians and 98.3% practiced in urban areas (37.3% of all counties). Geographic disparities were identified, with 1.09 physicians per 100,000 women in urban areas compared with 0.1 physicians per 100,000 women in rural areas. In total, 2,862 counties (57.4 million at-risk women) lacked an active physician. Additionally, there was no increase in rural physicians, with only 1.7% practicing in rural areas in 2016-2020 relative to 2.2% in 2001-2005 ( P =.35). Women in racial and ethnic minority populations, such as American Indian or Alaska Native and Hispanic women, exhibited the lowest level of access to physicians across all time periods. For example, 23.7% of American Indian or Alaska Native women did not have access to a physician within 100 miles between 2016 and 2020, which did not improve over time. Non-Hispanic Black women experienced an increase in relative accessibility, with a 26.2% increase by 2016-2020. However, Asian or Pacific Islander women exhibited significantly better access than non-Hispanic White, non-Hispanic Black, Hispanic, and American Indian or Alaska Native women across all time periods. CONCLUSION: Although the U.S. gynecologic oncologist workforce increased steadily over 20 years, this has not translated into evidence of improved access for many women from rural and underrepresented areas. However, health care utilization and cancer outcomes may not be influenced only by distance and availability. Policies and pipeline programs are needed to address these inequities in gynecologic cancer care.

Addressing indigenous health workforce inequities: a literature review exploring 'best' practice for recruitment into tertiary health programmes.

INTRODUCTION: Addressing the underrepresentation of indigenous health professionals is recognised internationally as being integral to overcoming indigenous health inequities. This literature review aims to identify 'best practice' for recruitment of indigenous secondary school students into tertiary health programmes with particular relevance to recruitment of Maori within a New Zealand context. METHODOLOGY/METHODS: A Kaupapa Maori Research (KMR) methodological approach was utilised to review literature and categorise content via: country; population group; health profession focus; research methods; evidence of effectiveness; and discussion of barriers. Recruitment activities are described within five broad contexts associated with the recruitment pipeline: Early Exposure, Transitioning, Retention/Completion, Professional Workforce Development, and Across the total pipeline. RESULTS: A total of 70 articles were included. There is a lack of published literature specific to Maori recruitment and a limited, but growing, body of literature focused on other indigenous and underrepresented minority populations.The literature is primarily descriptive in nature with few articles providing evidence of effectiveness. However, the literature clearly frames recruitment activity as occurring across a pipeline that extends from secondary through to tertiary education contexts and in some instances vocational (post-graduate) training. Early exposure activities encourage students to achieve success in appropriate school subjects, address deficiencies in careers advice and offer tertiary enrichment opportunities. Support for students to transition into and within health professional programmes is required including bridging/foundation programmes, admission policies/quotas and institutional mission statements demonstrating a commitment to achieving equity. Retention/completion support includes academic and pastoral interventions and institutional changes to ensure safer environments for indigenous students. Overall, recruitment should reflect a comprehensive, integrated pipeline approach that includes secondary, tertiary, community and workforce stakeholders. CONCLUSIONS: Although the current literature is less able to identify 'best practice', six broad principles to achieve success for indigenous health workforce development include: 1) Framing initiatives within indigenous worldviews 2) Demonstrating a tangible institutional commitment to equity 3) Framing interventions to address barriers to indigenous health workforce development 4) Incorporating a comprehensive pipeline model 5) Increasing family and community engagement and 6) Incorporating quality data tracking and evaluation. Achieving equity in health workforce representation should remain both a political and ethical priority.

Understanding the oversupply of physicians in Greece: the role of human resources planning, financing policy, and physician power.

Planning of the workforce has emerged as a critical issue in European health policy, as the need for human resources for health is changing in light of demographic, epidemiological, and socio-cultural trends and patterns of supply and demand in service provision. Greece represents a country with an oversupply of physicians, having the highest concentration of physicians among European Union countries. The study aims to analyze the factors influencing the high number of physicians in Greece and make policy recommendations. The analysis was conducted through international literature review and database searches. Neither the demography of the physician population in terms of age, gender composition, and geographic dispersion, nor the epidemiology of the Greek population, can explain the relatively high number of physicians in Greece. Despite the physician surplus, Greece faces serious geographical inequities regarding the distribution of physicians. There are also imbalances within the specialist category, with certain specialists (e.g., cardiologists) being in oversupply compared to other European countries, while others (e.g., general practitioners) remain weakly represented. Inadequate planning of human resources for health, inadequate health financing policy regarding primary care, gatekeeping mechanisms, and medical power constitute the primary themes explaining the trends of physicians' population in Greece.

The income divide in health care: how the Affordable Care Act will help restore fairness to the U.S. health system.

The new Commonwealth Fund Health Insurance Tracking Survey of U.S.Adults finds nearly three of five adults in families earning less than 133 percent of the federal poverty level were uninsured for a time in 2011; two of five were uninsured for one or more years. Low- and moderate-income adults who were uninsured during the year were much less likely to have a regular source of health care than people in the same income range who were insured all year. In addition, uninsured lower-income adults were more likely than insured adults in the same income group to cite factors other than medical emergencies as reasons for going to the emergency room. These included needing a prescription drug, not having a regular doctor, or saying that other places cost too much. The Affordable Care Act will substantially narrow these inequities through an extensive set of affordable coverage options starting in 2014.

Combining Drive Time and Urologist Density to Understand Access to Urologic Care.

OBJECTIVE: To improve our understanding of timely access to urologic care, we leveraged driving time combined with a measure of urologist density. MATERIALS AND METHODS: We identified all urologists who billed Medicare using National Provider Identifier in 2015 and geocoded their practice location. We developed drive-time based service areas for each provider using Esri's street network dataset stratified into 30, 60, 90, and 120-minute areas. Population characteristics were aggregated and block groups were assigned to a Hospital Referral Region. RESULTS: We identified 10,170 urologists that billed Medicare in 2015 in the United States. Compared to the northeast, vast expanses of land across the western United States have drive times to urology care >60 minutes. However, less than 13% of the US population is unable to obtain urologic care within 30 minutes. Likely reflecting rural populations, White and American Indian populations are represented in greater proportion among those requiring a longer drive time to urologic care. Disparities were noted between areas with timely access to a high versus low density of urologists; low density areas have a greater proportion of Black and Asian populations and greater income inequality. CONCLUSIONS: Drive time to urologists combined with urologist density is a novel approach to investigating urologic care access and a tool for health disparities research. While almost all of the US population lives within 1-hour drive time to a urologist there remains important differences in the population severed by high compared to low provider density.

China's human resources for health: quantity, quality, and distribution.

In this paper, we analyse China's current health workforce in terms of quantity, quality, and distribution. Unlike most countries, China has more doctors than nurses-in 2005, there were 1.9 million licensed doctors and 1.4 million nurses. Doctor density in urban areas was more than twice that in rural areas, with nurse density showing more than a three-fold difference. Most of China's doctors (67.2%) and nurses (97.5%) have been educated up to only junior college or secondary school level. Since 1998 there has been a massive expansion of medical education, with an excess in the production of health workers over absorption into the health workforce. Inter-county inequality in the distribution of both doctors and nurses is very high, with most of this inequality accounted for by within-province inequalities (82% or more) rather than by between-province inequalities. Urban-rural disparities in doctor and nurse density account for about a third of overall inter-county inequality. These inequalities matter greatly with respect to health outcomes across counties, provinces, and strata in China; for instance, a cross-county multiple regression analysis using data from the 2000 census shows that the density of health workers is highly significant in explaining infant mortality.

Disparities in Pediatric Provider Availability by Insurance Type After the ACA in California.

OBJECTIVE: To examine insurance-based disparities in provider-related barriers to care among children in California in the wake of changes to the insurance market resulting from the Affordable Care Act. METHODS: Our sample included 6514 children (ages 0 to 11 years) from the 2014-2016 California Health Interview Survey. We examined parent reports in the past year of 1) having trouble finding a general provider for the child, 2) the child not being accepted by a provider as a new patient, 3) the child's health insurance not being accepted by a provider, or 4) any of the above. Multivariable models estimated the associations of insurance type-Medi-Cal (Medicaid), employer-sponsored insurance, or privately purchased coverage-and parent reports of these problems. RESULTS: Approximately 8% of parents had encountered at least one of these problems. Compared with parents of children with employer-sponsored insurance, parents of children with Medi-Cal or privately purchased coverage had over twice the odds of experiencing at least one of the barriers. Parents of children with Medi-Cal had over twice the odds of being told a provider would not accept their children's coverage or having trouble finding a general provider and 3times the odds of being told a provider would not accept their children as new patients. Parents of children with privately purchased coverage had over 3times the odds of being told a provider would not accept their children's coverage. CONCLUSIONS: Our study found significant disparities in provider-related barriers by insurance type among children in California.

Equitable Health Care and Low-Density Living in the United States.

In 1818, John Sinclair's advice for health and longevity included temporary retirement to the country. Two centuries later, life in rural America means higher death rates throughout the lifespan. Health care delivery in rural areas is limited by a number of hardships associated with low-density living, including a shortage of providers, limited cultural diversity, and geography. There are both profound challenges and deep rewards associated with providing health care services in rural areas. Barring a major change in the health care financing and delivery systems, solutions for bringing a full range of quality health care and preventive services to rural residents include incentivizing a full range of providers to practice in rural areas; exploiting the delivery infrastructure that has developed in response to the explosive growth in e-commerce; taking advantage of cellular, digital, and satellite technologies; and learning about what motivates providers to choose rural practice settings.

Analysis of human resources for oral health globally: inequitable distribution.

BACKGROUND: Oral diseases affect most of the global population. The aim of this paper was to provide a contemporary analysis of 'human resources for oral health' (HROH) by examining the size and distribution of the dental workforce according to World Health Organization (WHO) region and in the most populous countries. METHOD: Publically available data on HROH and population size were sourced from the WHO, Central Intelligence Agency, United Nations, World Bank and the UK registration body. Population-to-dentist and dental-workforce ratios were calculated according to WHO region and for the 25 most populous countries globally. Workforce trends over time were examined for one high-income country, the UK. RESULTS: The majority of the world's 1.6 million dentists are based in Europe and the Americas, such that 69% of the world's dentists serve 27% of the global population. Africa has only 1% of the global workforce and thus there are marked inequalities in access to dental personnel, as demonstrated by population to dental-workforce ratios. Gaps exist in dental-workforce data, most notably relating to mid-level clinical providers, such as dental hygienists and therapists, and HROH data are not regularly updated. Workforce expansion and migration may result in rapid changes in dentist numbers. CONCLUSION: Marked inequalities in the distribution of global HROH exist between regions and countries, with inequalities most apparent in areas of high population growth. Detailed contemporary data on all groups of HROH are required to inform global workforce reform in support of addressing population oral health needs.

Comparing health care workforce in circumpolar regions: patterns, trends and challenges.

BACKGROUND: The eight Arctic States exhibit substantial health disparities between their remote northernmost regions and the rest of the country. This study reports on the trends and patterns in the supply and distribution of physicians, dentists and nurses in these 8 countries and 25 regions and addresses issues of comparability, data gaps and policy implications Methods: We accessed publicly available databases and performed three types of comparisons: (1) among the 8 Arctic States; (2) within each Arctic State, between the northern regions and the rest of the country; (3) among the 25 northern regions. The unit of comparison was density of health workers per 100,000 inhabitants, and the means of three 5-year periods from 2000 to 2014 were computed. RESULTS: The Nordic countries consistently exceed North America in the density of all three categories of health professionals, whereas Russia reports the highest density of physicians but among the lowest in terms of dentists and nurses. The largest disparities between "north" and "south" are observed in the Northwest Territories and Nunavut of Canada for physicians, and in Greenland for all three categories. The disparity is much less pronounced in the northern regions of Nordic countries, while Arctic Russia tends to be oversupplied in all categories. CONCLUSIONS: Despite efforts and standardisation of definitions by international organisations such as OECD, it is difficult to obtain an accurate and comparable estimate of the health workforce even in the basic categories of physicians, dentists and nurses . The use of head counts is particularly problematic in jurisdictions that rely on short-term visiting staff. Comparing statistics also needs to take into account the health care system, especially where primary health care is nurse-based.
