Geographic proximity to immunization providers and vaccine series completion among children ages 0-24 months.

OBJECTIVES: In the U.S., vaccination coverage is lower in rural versus urban areas. Spatial accessibility to immunization services has been a suspected risk factor for undervaccination in rural children. Our objective was to identify whether geographic factors, including driving distance to immunization providers, were associated with completion of recommended childhood vaccinations. METHODS: We analyzed records from Montana's immunization information system for children born 2015-2017. Using geolocated address data, we calculated distance in road miles from children's residences to the nearest immunization provider. A multivariable log-linked binomial mixed model was used to identify factors associated with completion of the combined 7-vaccine series by age 24 months. RESULTS: Among 26,085 children, 16,503 (63.3%) completed the combined 7-vaccine series by age 24 months. Distance to the nearest immunization provider ranged from 0 to 81.0 miles (median = 1.7; IQR = 3.2), with the majority (92.1%) of children living within 10 miles of a provider. Long distances (>10 miles) to providers had modest associations with not completing the combined 7-vaccine series (adjusted prevalence ratio [aPR]: 0.97, 95% confidence interval [CI]: 0.96-0.99). After adjustment for other factors, children living in rural areas (measured by rural-urban commuting area) were significantly less likely to have completed the combined 7-vaccine series than children in metropolitan areas (aPR: 0.88, 95% CI: 0.85-0.92). CONCLUSIONS: Long travel distances do not appear to be a major barrier to childhood vaccination in Montana. Other challenges, including limited resources for clinic-based strategies to promote timely vaccination and parental vaccine hesitancy, may have greater influence on rural childhood vaccination.

Geographic access to care and pediatric surgical outcomes.

INTRODUCTION: Rurality and distance traveled for healthcare are associated with worse pediatric health indicators. METHODS: We retrospectively analyzed patients ages 0-21 at a quaternary pediatric surgical facility with a large rural catchment area between 1/1/2016-12/31/2020. Patient addresses were designated as metropolitan or non-metropolitan. 60- and 120-min driving rings from our institution were calculated. Logistic regression assessed the effect of rurality and distance traveled for care on postoperative mortality and serious adverse events (SAE). RESULTS: Among 56,655 patients, 84.3% were from metropolitan areas, 8.4% from non-metropolitan areas, and 7.3% could not be geocoded. 64% were within 60-min driving and 80% within 120-min. On univariable regression, patients living >120-min experienced 59% (95% CI: 1.09, 2.30) increased odds of mortality and 97% (95% CI: 1.84, 2.12) increased odds of SAE compared to those <60-min. Non-metropolitan patients experienced 38% (95% CI: 1.26, 1.52) increased odds of a serious postoperative event compared to metropolitan patients. DISCUSSION: Efforts to improve geographic access to pediatric care are needed to mitigate the impact of rurality and travel time on inequitable surgical outcomes.

Building More Bridges: Indigenous leadership in a study assessing the impact of distance to care on markers of quality HIV care in Saskatchewan.

Introduction: Individuals in rural and remote areas face barriers to chronic disease care, including HIV. Saskatchewan has the highest HIV incidence among Canadian provinces and 35.6% of the population lives outside of an urban centre. In this study, we explored the relationship between distance to HIV care and markers of quality HIV care in Saskatchewan as part of the Canadian Observational HIV Cohort (CANOC). Methods: We used a Two-Eyed Seeing approach and honoured the experience of Indigenous team members living with HIV. The Positive Partnership Score (PPS) was the primary outcome (including frequency of viral load and CD4 measurements, baseline CD4 count, antiretroviral medication regimen and virologic suppression). Multivariable linear regression analysis was performed with distance to care defined in two ways: (1) categorical based on distance from home to HIV specialist care and (2) road distance from CANOC enrolment site. Results: Two hundred and seventy-six individuals were included in the analyses. Living ≤25 km from a visiting HIV specialist (where no HIV specialist lives in the community permanently) and living >100 km from the closest HIV specialist (either visiting or permanent) were both associated with lower PPS compared to living ≤25 km from where an HIV specialist practises permanently. Each 10 km further from the CANOC enrolment site was associated with a 0.01-point reduction (95% CI-0.02, 0, P = 0.024) in PPS. Conclusion: Through a strength-based approach that was grounded in culture, connection, land and Ceremony, we demonstrated how Indigenous people with HIV can play a key role in research. Distance from care was associated with a poorer quality of HIV care in Saskatchewan highlighting the need for better rural HIV care.

Résumé Introduction: Les personnes vivant dans les régions rurales et éloignées sont confrontées à des obstacles aux soins des maladies chroniques, y compris le VIH. La Saskatchewan a l'incidence du VIH la plus élevée parmi les provinces canadiennes et 35,6% de la population vit en dehors d'un centre urbain. Dans cette étude, nous avons exploré le lien entre la distance aux soins du VIH et les marqueurs de la qualité des soins du VIH en Saskatchewan dans le cadre de la Canadian Observational HIV Cohort (CANOC). Méthodes: Nous avons utilisé l'approche de "regard des deux yeux" et honoré l'expérience des membres autochtones de l'équipe vivant avec le VIH. Le score de partenariat positif (SPP/PPS) était le résultat primaire (incluant la fréquence des mesures de la charge virale et des CD4, le nombre de CD4 de base, le régime de médicaments antirétroviraux et la suppression virologique). Une analyse de régression linéaire multivariable a été effectuée avec la distance aux soins définie de deux manières: 1) catégorique, basée sur la distance entre le domicile et les soins d'un spécialiste du VIH, et 2) distance routière du site d'inscription au CANOC. Résultats: 276 individus ont été inclus dans les analyses. Le fait de vivre à ≤25 km d'un spécialiste du VIH en visite (lorsqu'aucun spécialiste du VIH ne vit en permanence dans la collectivité) et le fait de vivre à >100 km du spécialiste du VIH le plus proche (en visite ou en permanence) étaient tous deux associés à un SPP plus faible par rapport au fait de vivre à ≤25 km du lieu où un spécialiste du VIH exerce en permanence. Chaque tranche de 10 km plus éloignée du site d'inscription de CANOC était associée à une réduction de 0,01 point (IC 95%:-0,02, 0, P = 0,024) du PPS. Conclusion: Grâce à une approche fondée sur les forces et ancrée dans la culture, les liens, la terre et les cérémonies, nous avons démontré comment les autochtones atteints du VIH peuvent jouer un rôle clé dans la recherche. La distance par rapport aux soins était associée à une moins bonne qualité des soins du VIH en Saskatchewan, ce qui souligne la nécessité d'améliorer les soins du VIH en milieu rural. Mots-clés: VIH, Saskatchewan, leadership autochtone, distance par rapport aux soins.

Socioeconomic status, access to care, risk factor patterns, and stage at diagnosis for head and neck cancer among black and white patients.

BACKGROUND: Little is known about how factors combine to influence progression of squamous cell carcinoma of the head and neck (HNSCC). We aimed to evaluate multidimensional influences of factors associated with HNSCC stage by race. METHODS: Using retrospective data, patients with similar socioeconomic status (SES), access to care (travel time/distance), and behavioral risk factors (tobacco/alcohol use and dental care) were grouped by latent class analysis. Relative frequency differences (RFD) were calculated to evaluate latent classes by stage, race, and p16 status. RESULTS: We identified three latent classes. Advanced T-stage was higher for black (RFD = +20.2%; 95% CI: -4.6 to 44.9) than white patients (RFD = +10.7%; 95% CI: 2.1-19.3) in the low-SES/high-access/high-behavioral risk class and higher for both black (RFD = +29.6%; 95% CI: 4.7-54.5) and white patients (RFD = +23.9%; 95% CI: 15.2-32.6) in the low-SES/low-access/high-behavioral risk class. CONCLUSION: Results suggest that SES, access to care, and behavioral risk factors combine to underly the association with advanced T-stage. Additionally, differences by race warrant further investigation.

Geographic barriers to children's surgical care: A systematic review of existing evidence.

BACKGROUND: Ensuring that children have access to timely and appropriate surgical care is a vital component of comprehensive pediatric care. This study systematically reviews the existing evidence related to geographic barriers in children's surgery. METHODS: Medline and Scopus databases were searched for any English language studies that examined associations between geographic burden (rural residence or distance to care) and a quantifiable outcome within pediatric surgical subspecialties. Two independent reviewers extracted data from each study. RESULTS: From 6331 studies screened, 22 studies met inclusion criteria. Most studies were retrospective analyses and conducted in the U.S. or Canada (14 and three studies, respectively); five were conducted outside North America. In transplant surgery (seven studies), greater distance from a transplant center was associated with higher waitlist mortality prior to kidney and liver transplantation, although graft outcomes were generally similar. In congenital cardiac surgery (five studies), greater travel was associated with higher neonatal mortality and older age at surgery but not with post-operative outcomes. In general surgery (eight studies), rural residence was associated with increased rates of perforated appendicitis, higher frequency of negative appendectomy, and increased length of stay after appendectomy. In orthopedic surgery (one study), rurality was associated with decreased post-operative satisfaction. No evidence for disparate outcomes based upon distance or rurality was identified in neurosurgery (one study). CONCLUSIONS: Substantial evidence suggests that geographic barriers impact the receipt of surgical care among children, particularly with regard to transplantation, congenital cardiac surgery, and appendicitis.

Follow-Up Care Barriers for Patients with Orofacial Clefts.

OBJECTIVE: The aim of this study was to evaluate whether a patient with a cleft's age, associated syndrome, cleft phenotype or travel distance affects their follow-up rate. DESIGN: This study is a retrospective review of patients with CL/P treated by a craniofacial clinic. SETTING: The setting was a craniofacial clinic at a tertiary care university hospital. PATIENTS, PARTICIPANTS: Candidates were patients seen by the craniofacial clinic between January 2007 and December 2019. An initial pool of 589 patients was then reduced to 440 due to exclusion criteria. INTERVENTIONS: None. MAIN OUTCOME MEASURE(S): The outcome measure was actual patient attendance to the craniofacial team compared to the team goal expectation of annual return visits. RESULTS: The mean age of participants at the end of the study was 9.0 ± 5.4 years with a mean follow-up period (total possible follow-up period length based on patient age at presentation and study window) of 5.5 ± 3.6 years. There was no association between cleft phenotype, type of syndrome, or distance to the clinic with attendance. Children with syndromes had an 11% decrease in the odds of attending follow-up visits with each 1-year increase in age compared to a 4% decrease in children without syndromes. CONCLUSIONS: The only significant factors determining patient attendance were the presence of a syndrome and increasing age.

Health Care Access Measures and Palliative Care Use by Race/Ethnicity among Metastatic Gynecological Cancer Patients in the United States.

Palliative care improves quality-of-life and extends survival, however, is underutilized among gynecological cancer patients in the United States (U.S.). Our objective was to evaluate associations between healthcare access (HCA) measures and palliative care utilization among U.S. gynecological cancer patients overall and by race/ethnicity. We used 2004-2016 data from the U.S. National Cancer Database and included patients with metastatic (stage III-IV at-diagnosis) ovarian, cervical, and uterine cancer (n = 176,899). Palliative care was defined as non-curative treatment and could include surgery, radiation, chemotherapy, and pain management, or any combination. HCA measures included insurance type, area-level socioeconomic measures, distance-to-care, and cancer treatment facility type. We evaluated associations of HCA measures with palliative care use overall and by race/ethnicity using multivariable logistic regression. Our population was mostly non-Hispanic White (72%), had ovarian cancer (72%), and 24% survived <6 months. Five percent of metastatic gynecological cancer patients utilized palliative care. Compared to those with private insurance, uninsured patients with ovarian (aOR: 1.80,95% CI: 1.53-2.12), and cervical (aOR: 1.45,95% CI: 1.26-1.67) cancer were more likely to use palliative care. Patients with ovarian (aOR: 0.58,95% CI: 0.48-0.70) or cervical cancer (aOR: 0.74,95% CI: 0.60-0.88) who reside >45 miles from their provider were less likely to utilize palliative care than those within <2 miles. Ovarian cancer patients treated at academic/research programs were less likely to utilize palliative care compared to those treated at community cancer programs (aOR: 0.70, 95%CI: 0.58-0.84). Associations between HCA measures and palliative care utilization were largely consistent across U.S. racial-ethnic groups. Insurance type, cancer treatment facility type, and distance-to-care may influence palliative care use among metastatic gynecological cancer patients in the U.S.

Cervical cancer treatment initiation and survival: The role of residential proximity to cancer care.

OBJECTIVE: To examine the role of driving time to cancer care facilities on days to cancer treatment initiation and cause-specific survival for cervical cancer patients. METHODS: A retrospective cohort analysis of patients diagnosed with invasive cervical cancer during 2001-2016, using South Carolina Central Cancer Registry data linked to vital records. Kaplan-Meier survival curves and Cox proportional hazards models were used to examine the association of driving times to both a patient's nearest and actual cancer treatment initiation facility with cause-specific survival and time to treatment initiation. RESULTS: Of 2518 eligible patients, median cause-specific survival was 49 months (interquartile, 17-116) and time to cancer treatment initiation was 21 days (interquartile, 0-40). Compared to patients living within 15 min of the nearest cancer provider, those living more than 30 min away were less likely to receive initial treatment at teaching hospitals, Joint Commission accredited facilities, and/or Commission on Cancer accredited facilities. After controlling for patient, clinical, and provider characteristics, no significant associations existed between driving times to the nearest cancer provider and survival/time to treatment. When examining driving times to treatment initiation (rather than simply nearest) provider, patients who traveled farther than 30 min to their actual providers had delayed initiation of cancer treatment (hazard ratio, 0.81; 95% confidence interval, 0.73-0.90), including surgery (0.82; 95% CI, 0.72-0.92) and radiotherapy (0.82, 95% CI, 0.72-0.94). Traveling farther than 30 min to the first treating provider was not associated with worse cause-specific survival. CONCLUSIONS: For cervical cancer patients, driving time to chosen treatment providers, but not to the nearest cancer care provider, was associated with prolonged time to treatment initiation. Neither was associated with survival.

Effects of service changes affecting distance/time to access urgent and emergency care facilities on patient outcomes: a systematic review.

BACKGROUND: Reconfiguration of urgent and emergency care services often increases travel time/distance for patients to reach an appropriate facility. Evidence of the effects of reconfiguration is important for local communities and commissioners and providers of health services. METHODS: We performed a systematic review of the evidence regarding effects of service reconfigurations that increase the time/distance for some patients to reach an urgent and emergency care (UEC) facility. We searched seven bibliographic databases from 2000 to February 2019 and used citation tracking and reference lists to identify additional studies. We included studies of any design that compared outcomes for people with conditions requiring emergency treatment before and after service reconfiguration with an associated change in travel time/distance to access UEC. Studies had to be conducted in the UK or other developed countries. Data extraction and quality assessment (using the Joanna Briggs Institute checklist for quasi-experimental studies) were undertaken by a single reviewer with a sample checked for accuracy and consistency. We performed a narrative synthesis of the included studies. Overall strength of evidence was assessed using a previously published method that considers volume, quality and consistency. RESULTS: We included 12 studies, of which six were conducted in the USA, two in the UK and four in other European countries. The studies used a variety of observational designs, with before-after and cohort designs being most common. Only two studies included an independent control site/sites where no reconfiguration had taken place. The reconfigurations evaluated in these studies reported relatively small effects on average travel times/distance. DISCUSSION: For studies of general UEC populations, there was no convincing evidence as to whether reconfiguration affected mortality risk. However, evidence of increased risk was identified from studies of patients with acute myocardial infarction, particularly 1 to 4 years after reconfiguration. Evidence for other conditions was inconsistent or very limited. CONCLUSIONS: We found insufficient evidence to determine whether increased distance to UEC increases mortality risk for the general population of people requiring UEC, although this conclusion may not extend to people with specific conditions.

From far and wide: Geographic distance to pediatric surgical care across Canada.

PURPOSE: Canada is the second largest country in the world, with most of the population located in the southern-most portion of its geography. We sought to define the relative distribution of pediatric surgeons to potential pediatric patients using data from the Canadian census. METHODS: The 2011 Canadian Census and a convenience sample of current Canadian pediatric surgeons were used to calculate straight-line distances between pediatric surgeon postal code centroids and census dissemination block centroids. RESULTS: Currently, there are 74 practicing pediatric surgeons in Canada; 493,345 populated census blocks were identified, and 7,752,075 children were enumerated. The median (IQR) kilometers to the closest pediatric surgeon was 27.99 (11.35, 85.47) kilometers, and 22.7% of Canadian children lived more than 100 km from care. Nearly 13% of children lived greater than 200 km from the nearest pediatric surgeon. CONCLUSION: More than 1.7 million Canadian children, nearly one quarter of all Canadian children, live greater than 100 km from the closest pediatric surgeon. This identifies a disparate group of patients who do not have an equal access-to-care as compared to others in the country. LEVEL OF EVIDENCE: Level IV.

What Characteristics Influence Whether Rural Beneficiaries Receiving Care From Urban Hospitals Return Home for Skilled Nursing Care?

PURPOSE: Skilled nursing care (SNC) provides Medicare beneficiaries short-term rehabilitation from an acute event. The purpose of this study is to assess beneficiary, market, and hospital factors associated with beneficiaries receiving care near home. METHODS: The population includes Medicare beneficiaries who live in a rural area and received acute care from an urban facility in 2013. "Near home" was defined 3 different ways based on distances from the beneficiary's home to the nearest source of SNC. Results include unadjusted means and odds ratios from logistic regression. FINDINGS: About 69% of rural beneficiaries receiving acute care in an urban location returned near home for SNC. Beneficiaries returning home were white (odds ratio [OR] black: 0.69; other race: 0.79); male (OR: 1.07); older (OR age 85+ [vs 65-69]: 1.14); farther from SNC (OR: 1.01 per mile); closer to acute care (OR: 0.28, logged miles); and received acute care from hospitals that did not own a skilled nursing facility (owned OR: 0.77) and hospitals with: no swing bed (swing bed OR: 0.47), high case mix (OR: 3.04), and nonprofit status (for-profit OR: 0.85). Results varied somewhat across definitions of "near home." CONCLUSIONS: Rural Medicare beneficiaries who received acute care far from home were more likely to receive SNC far from home. Because Medicare beneficiaries have the choice of where to receive SNC, policy makers may consider ensuring that new payment models do not incentivize provision of SNC away from home.

Factors Associated with Duration of Overall Treatment Time for Cervical Cancer Treated with Definitive Chemoradiotherapy.

Introduction For women with intact cervical cancer treated by definitive chemoradiotherapy, the adverse impact of treatment prolongation is well-established. We aimed to identify potentially modifiable factors associated with the unwanted increase in the time required to complete the prescribed course of therapy. Methods We retrospectively examined treatment records of 104 consecutive cervical cancer patients receiving chemoradiation for cervical cancer, which included cervical high-dose-rate intracavitary brachytherapy performed at a single referral center. Association of factors, including distance to care, driving time, and income level with overall treatment time, was explored. Results Guideline-concordant treatment duration was achieved in 34% of cases. There was no significant correlation between treatment duration and any of the patient-related characteristics assessed in this study. Transitioning of the radiation oncology physician staffing at the brachytherapy center from a private practice non-integrated group to a large integrated group was associated with a decrease in mean overall treatment time, 61 vs. 68 days, p = 0.007. Conclusions We did not identify a modifiable patient-related factor amenable to a financial intervention. Administration of brachytherapy within an integrated system resulted in a shortened duration of the entire course of therapy for intact cervical cancer.

Methodological Challenges When Studying Distance to Care as an Exposure in Health Research.

Distance to care is a common exposure and proposed instrumental variable in health research, but it is vulnerable to violations of fundamental identifiability conditions for causal inference. We used data collected from the Botswana Birth Outcomes Surveillance study between 2014 and 2016 to outline 4 challenges and potential biases when using distance to care as an exposure and as a proposed instrument: selection bias, unmeasured confounding, lack of sufficiently well-defined interventions, and measurement error. We describe how these issues can arise, and we propose sensitivity analyses for estimating the degree of bias.

Geographic distance to pediatric surgical care within the continental United States.

PURPOSE: Geographic proximity to pediatric surgical care has not been evaluated using the Decennial Census nor have racial, ethnic, gender, or urbanization variations been reported. This study's aim is to describe proximity of children living in the continental U.S. to a pediatric surgeon with respect to these variations. METHODS: The 2010 American Pediatric Surgical Association member file and the 2010 Decennial Census were used to calculate straight-line distances between pediatric surgeons' zip code centroids and census block centroids. RESULTS: In 2010, 716 practicing pediatric surgeons were identified, 6,182,882 populated Census blocks were identified, and 73,690,271 children were enumerated. Of white non-Hispanic children, 30.1% lived greater than 40 miles from care. Of Native American children, 40.5% lived more than 60 miles from care. Among children 0-5 years of age, the median (IQR) miles to closest pediatric surgeon was 14.2 (6.2, 39.6), and 3,010,698 of these children lived more than 60 miles from care. CONCLUSION: More than 10 million children lived greater than 60 miles from a pediatric surgeon in 2010. Racial, ethnic, age, and urbanization variations in proximity to pediatric surgeons were present. This method is feasible to describe distance-to-care with the upcoming 2020 Decennial Census and may benefit future allocation of pediatric surgeons. LEVEL OF EVIDENCE: IV.

Evaluating the urban-rural paradox: The complicated relationship between distance and the receipt of guideline-concordant care among cervical cancer patients.

OBJECTIVE: Urban-rural health disparities are often attributed to the longer distances rural patients travel to receive care. However, a recent study suggests that distance to care may affect urban and rural cancer patients differentially. We examined whether this urban-rural paradox exists among patients with cervical cancer. METHODS: We identified individuals diagnosed with cervical cancer from 2004 to 2013 using a statewide cancer registry linked to multi-payer, insurance claims. Our primary outcome was receipt of guideline-concordant care: surgery for stages IA1-IB1; external beam radiation therapy (EBRT), concomitant chemotherapy, and brachytherapy for stages IB2-IVA. We estimated risk ratios (RR) using modified Poisson regressions, stratified by urban/rural location, to examine the association between distance to nearest facility and receipt of treatment. RESULTS: 62% of 999 cervical cancer patients received guideline-concordant care. The association between distance and receipt of care differed by type of treatment. In urban areas, cancer patients who lived ≥15 miles from the nearest surgical facility were less likely to receive primary surgical management compared to those <5 miles from the nearest surgical facility (RR: 0.77, 95% CI: 0.60-0.98). In rural areas, patients living ≥15 miles from the nearest brachytherapy facility were more likely to receive treatment compared to those <5 miles from the nearest brachytherapy facility (RR: 1.71, 95% CI: 1.14-2.58). Distance was not associated with the receipt of chemotherapy or EBRT. CONCLUSIONS: Among cervical cancer patients, there is evidence supporting the urban-rural paradox, i.e., geographic distance to cancer care facilities is not consistently associated with treatment receipt in expected or consistent ways. Healthcare systems must consider the diverse and differential barriers encountered by urban and rural residents to improve access to high quality cancer care.

Distance to care, care seeking and child mortality in rural Burkina Faso: findings from a population-based cross-sectional survey.

OBJECTIVE: Although distance has been identified as an important barrier to care, evidence for an effect of distance to care on child mortality is inconsistent. We investigated the association of distance to care with self-reported care seeking behaviours, neonatal and post-neonatal under-five child mortality in rural areas of Burkina Faso. METHODS: We performed a cross-sectional survey in 14 rural areas from November 2014 to March 2015. About 100 000 women were interviewed on their pregnancy history and about 5000 mothers were interviewed on their care seeking behaviours. Euclidean distances to the closest facility were calculated. Mixed-effects logistic and Poisson regressions were used respectively to compute odds ratios for care seeking behaviours and rate ratios for child mortality during the 5 years prior to the survey. RESULTS: Thirty per cent of the children lived more than 7 km from a facility. After controlling for confounding factors, there was a strong evidence of a decreasing trend in care seeking with increasing distance to care (P ≤ 0.005). There was evidence for an increasing trend in early neonatal mortality with increasing distance to care (P = 0.028), but not for late neonatal mortality (P = 0.479) and post-neonatal under-five child mortality (P = 0.488). In their first week of life, neonates living 7 km or more from a facility had an 18% higher mortality rate than neonates living within 2 km of a facility (RR = 1.18; 95%CI 1.00, 1.39; P = 0.056). In the late neonatal period, despite the lack of evidence for an association of mortality with distance, it is noteworthy that rate ratios were consistent with a trend and similar to or larger than estimates in early neonatal mortality. In this period, neonates living 7 km or more from a facility had an 18% higher mortality rate than neonates living within 2 km of a facility (RR = 1.18; 95%CI 0.92, 1.52; P = 0.202). Thus, the lack of evidence may reflect lower power due to fewer deaths rather than a weaker association. CONCLUSION: While better geographic access to care is strongly associated with increased care seeking in rural Burkina Faso, the impact on child mortality appears to be marginal. This suggests that, in addition to improving access to services, attention needs to be paid to quality of those services.

Geographic proximity to specialized pediatric neurosurgical care in the contiguous United States.

OBJECTIVE Absent from an analysis of supply is consideration of the geographic distribution of pediatric neurosurgeons. Several patient socioeconomic metrics are known to be associated with outcome in pediatric neurosurgical diseases, such as hydrocephalus. The purpose of this study was to determine current geographic proximity to pediatric neurosurgical care using professional society databases. This study also sought to establish how socioeconomic factors are related to distance to care, using federal government-collected data. METHODS A list of currently practicing American Board of Pediatric Neurological Surgery (ABPNS)-certified neurosurgeons was compiled (ABPNS group). A separate list of practicing members of the Joint Pediatric Section (JPS) of the American Association of Neurological Surgeons/Congress of Neurological Surgeons was prepared (JPS group). Current primary practice locations were collected from each professional society database for each ABPNS or JPS neurosurgeon and were charted using ArcGIS mapping software (ESRI, version 10.3) on a United States Census Bureau map. The straight distance from the centroid of each zip code tabulation area (ZCTA) to the nearest neurosurgeon was determined by group type of neurosurgeon (ABPNS vs ABPNS + JPS). ZCTA-level data on demographic and socioeconomic factors were acquired from the American Community Survey, including data in children and young adults (0-18 or 0-24 years old) and the general population. These data were compared by distance to care and by groups of neurosurgeons (Pearson's chi-square analysis; the threshold of significance was set at 0.05). RESULTS Three hundred fifty-five practicing neurosurgeons providing pediatric care were located, of whom 215 surgeons were certified by the ABPNS and 140 were JPS members only. The analysis showed that 1 pediatric neurosurgeon is in practice for every 289,799 persons up to the age of 24 years. The average distance between a ZCTA and the nearest pediatric neurosurgeon is 63.3 miles (SE 0.3, range 0.0-499.7 miles). Geographic analysis showed that 27.1% of children live farther than 60 miles from an ABPNS-certified neurosurgeon and 19.7% from either an ABPNS-certified neurosurgeon or a JPS member. ZCTAs with children who live farther than 60 miles from a neurosurgeon providing pediatric care had a marginally higher rate of uninsured children, a higher percentage of families with children living below the federal poverty level, and a higher proportion of persons living in rural areas compared with ZCTAs with children who live within 60 miles of care (p < 0.005 for each finding). CONCLUSIONS The results of this study indicate that there is considerable variation in proximity to pediatric neurosurgical subspecialty care by geographic region. In addition, there is a relationship between distance to neurosurgical care and socioeconomic indicators. Optimization of access to pediatric neurosurgical care may involve strategies to overcome long geographic distances, particularly in rural and underserved areas. Such areas may have disproportionately lower socioeconomic levels, which may further limit access to care and affect outcomes. Both the total number of pediatric neurosurgeons per pediatric population and their geographic distribution could be important in determining appropriate subspecialty supply factors (e.g., the number of accredited pediatric neurosurgical fellowship training programs), as well as being important drivers of neurosurgical patient outcomes.

Patients with localized non-small cell lung cancer miss out on curative surgery with distance from specialist care.

BACKGROUND: To determine whether increasing distance to the nearest accessible specialist hospital (NASH, a public hospital with a thoracic surgical service) increases a patient's likelihood of missing out on curative surgery for localized non-small cell lung cancer (NSCLC). METHOD: Population-based study of cancer registry records for 27 033 people with lung cancer diagnosed in New South Wales, Australia, between 2000 and 2008 linked to hospital admission records. This analysis includes 3240 patients with localized NSCLC admitted to hospital within 12 months of diagnosis. RESULTS: Patients who lived 100+ km from the NASH were more likely to have no surgery (50.6%) than those living 0-39 km away (37.6%) and more likely to attend general hospitals for their care (52.2% at 100+ km, 14.8% at 0-39 km). Relative to patients living 0-39 km from the NASH and attending a specialist hospital for their care, the odds ratio (OR) of not having surgery was high if patients attended a general hospital (adjusted OR 5.99, 95% confidence interval (CI) 3.87-9.26, for those 0-39 km distant) and even higher as distance from the NASH increased (24.68, 95% CI 12.37-49.13 for 40-49 km and 30.10, 95% CI 18.2-49.40 for 100+ km). For patients treated in specialist hospitals (public or private), the trend with distance was opposite: relative to 0-39 km, the OR was 0.29 (95% CI 0.15-0.50) at 40-99 km and 0.14 (95% CI 0.08-0.26) at 100+ km. CONCLUSIONS: Patients with localized NSCLC are most likely to have no potentially curative surgery if they live distant from a specialist hospital and attend a general hospital for their care.
