Harnessing Geographic Information Systems (GIS) to enable community-oriented primary care.

BACKGROUND: Despite growing acceptance and implementation of geographic information systems (GIS) in the public health arena, its utility for clinical population management and coordination by leaders in a primary care clinical health setting has been neither fully realized nor evaluated. METHODS: In a primary care network of clinics charged with caring for vulnerable urban communities, we used GIS to (1) integrate and analyze clinical (practice management) data and population (census) data and (2) generate distribution, service area, and population penetration maps of those clinics. We then conducted qualitative evaluation of the responses of primary care clinic leaders, administrators, and community board members to analytic mapping of their clinic and regional population data. RESULTS: Practice management data were extracted, geocoded, and mapped to reveal variation between actual clinical service areas and the medically underserved areas for which these clinics received funding, which was surprising to center leaders. In addition, population penetration analyses were performed to depict patterns of utilization. Qualitative assessments of staff response to the process of mapping clinical and population data revealed enthusiastic engagement in the process, which led to enhanced community comprehension, new ideas about data use, and an array of applications to improve their clinical revenue. However, they also revealed barriers to further adoption, including time, expense, and technical expertise, which could limit the use of GIS and mapping unless economies of scale across clinics, the use of web technology, and the availability of dynamic mapping tools could be realized. CONCLUSIONS: Analytic mapping was enthusiastically received and practically applied in the primary care setting, and was readily comprehended by clinic leaders for innovative purposes. This is a tool of particular relevance amid primary care safety-net expansion and increased funding of health information technology diffusion in these settings, particularly if the hurdles of cost and technological expertise are overcome by harnessing new advances in web-based mapping technology.

Morbidity in obese adolescents who meet the adult National Institutes of Health criteria for bariatric surgery.

PURPOSE: Some have suggested that the criteria for weight loss surgery in adolescents be stricter than those currently recommended for adults by the National Institutes of Health (NIH). The aim of the current study is to define the characteristics of adolescents who meet NIH consensus criteria for bariatric surgery in adults to determine their level of morbidity. MATERIALS AND METHODS: Using the Medical Expenditure Panel Survey 2000-2004, children designated as meeting NIH criteria were 13 to 17 years of age with (1) a body mass index >or=40 or (2) a body mass index >35, and one or more comorbidity. We contrasted surgery candidates with noncandidates. We examined items that comprise a screener for identifying children with special health care needs. The Columbia Impairment Scale (CIS) was used to assess child functioning. RESULTS: There were 134 children identified as candidates for bariatric surgery and 4736 noncandidates in the same age range. Candidates were more likely to have special health care needs (36% vs 23%) and more likely to have a CIS above 16 (34% vs 16%). Candidates for weight loss surgery were 2.36 times as likely to have a CIS score of 16 or higher and 1.87 times as likely to be identified as a child with special health care needs (P

Increased rates and severity of child and adult food insecurity in households with adult smokers.

OBJECTIVE: To investigate rates and severity of child and adult food insecurity (the inability to access enough food in a socially acceptable way for every day of the year) in households with and without smokers. DESIGN: Cross-sectional survey. SETTING: Nationally representative sample of the US population from 1999 to 2002. PARTICIPANTS: Households with children through age 17 years (n = 8817) in the National Health and Nutrition Examination Survey. Main Exposure Presence or absence of adult smokers in the household. Covariates included age, sex, and race/ethnicity of the child, and the poverty index ratio. Main Outcome Measure Rates and severity of food insecurity were ascertained using the US Department of Agriculture Food Security Survey Module. RESULTS: Food insecurity was more common and severe in children and adults in households with smokers. Of children in households with smokers, 17.0% were food insecure vs 8.7% in households without smokers (P < .001). Rates of severe child food insecurity were 3.2% vs 0.9% (P < .04), respectively. For adults, 25.7% in households with smokers and 11.6% in households without smokers were food insecure, and rates of severe food insecurity were 11.8% and 3.9%, respectively (P < .003 for each). Food insecurity was higher in low-income compared with higher income homes (P < .01). At multivariate analyses, smoking was independently associated with food insecurity and severe food insecurity in children (adjusted odds ratio, 2.0; 95% confidence interval, 1.5-2.7, and adjusted odds ratio, 3.1; 95% confidence interval, 1.4-6.9, respectively) and adults (adjusted odds ratio, 2.2; 95% confidence interval, 1.6-3.0, and adjusted odds ratio, 2.3; 95% confidence interval, 1.4-3.7, respectively). CONCLUSIONS: Living with adult smokers is an independent risk factor for adult and child food insecurity, associated with an approximate doubling of its rate and tripling of the rate of severe food insecurity.

Impact of Title VII training programs on community health center staffing and national health service corps participation.

PURPOSE: Community health centers (CHCs) are a critical component of the health care safety net. President Bush's recent effort to expand CHC capacity coincides with difficulty recruiting primary care physicians and substantial cuts in federal grant programs designed to prepare and motivate physicians to practice in underserved settings. This article examines the association between physicians' attendance in training programs funded by Health Resources and Services Administration (HRSA) Title VII Section 747 Primary Care Training Grants and 2 outcome variables: work in a CHC and participation in the National Health Service Corps Loan Repayment Program (NHSC LRP). METHODS: We linked the 2004 American Medical Association Physician Master-file to HRSA Title VII grants files, Medicare claims data, and data from the NHSC. We then conducted retrospective analyses to compare the proportions of physicians working in CHCs among physicians who either had or had not attended Title VII-funded medical schools or residency programs and to determine the association between having attended Title VII-funded residency programs and subsequent NHSC LRP participation. RESULTS: Three percent (5,934) of physicians who had attended Title VII-funded medical schools worked in CHCs in 2001-2003, compared with 1.9% of physicians who attended medical schools without Title VII funding (P<.001). We found a similar association between Title VII funding during residency and subsequent work in CHCs. These associations remained significant (P<.001) in logistic regression models controlling for NHSC participation, public vs private medical school, residency completion date, and physician sex. A strong association was also found between attending Title VII-funded residency programs and participation in the NHSC LRP, controlling for year completed training, physician sex, and private vs public medical school. CONCLUSIONS: Continued federal support of Title VII training grant programs is consistent with federal efforts to increase participation in the NHSC and improve access to quality health care for underserved populations through expanded CHC capacity.

Changing policies on vaginal birth after cesarean: impact on access.

BACKGROUND: The issue of vaginal birth after cesarean (VBAC) has become highly visible and contentious. In 1999, the American College of Obstetricians and Gynecologists advocated a policy that surgical capability be "immediately available" for women in labor attempting VBAC. METHODS: Every hospital in Colorado, Montana, Oregon, and Wisconsin was contacted by telephone at least once during the period 2003 to 2005. Using a semistructured interview, respondent hospitals were asked whether and when their policies for VBAC had changed and what was the availability of VBAC services before and after the 1999 policy was issued. RESULTS: Of 314 hospitals contacted, 312 responded to the survey (response rate 99.4%). Babies were delivered at 230 (74%) respondent hospitals. Almost one-third, 68 of 222 (30.6%), of responding delivery hospitals that previously offered VBAC services had stopped doing so; seven hospitals had never allowed VBAC. Of the hospitals that still allowed VBAC, 68 percent had changed their VBAC policies since 1999, with the most frequent changes requiring the in-house presence of surgery (53%) and anesthesia (44%) personnel when women desiring VBAC presented in labor. Compared with hospitals that stopped allowing VBAC, those that currently permit VBAC were larger (156.6 vs 58.1 beds, t = 7.02, p < 0.001), closer to other delivery hospitals (20.9 vs 39.2 miles, t = 4.33, p < 0.001), annually delivered more babies (1009.9 vs 458.3, t = 4.41, p < 0.001), and annually had more cesarean deliveries (226.7 vs 105.7, t = 3.91, p < 0.001). CONCLUSIONS: In the years following advocacy of the 1999 policy, the availability of VBAC services significantly decreased, especially among smaller or more isolated hospitals.

Physical inactivity in adult survivors of childhood acute lymphoblastic leukemia: a report from the childhood cancer survivor study.

PURPOSE: To determine if adult survivors of childhood acute lymphoblastic leukemia (ALL) are less active (and more inactive) than the general population and to identify modifying factors. PATIENTS AND METHODS: Physical activity was assessed by self-report in 2,648 adult survivors of the Childhood Cancer Survivor Study. Participants in the Behavioral Risk Factor Surveillance System (BRFSS) survey administered through the Centers for Disease Control and Prevention (CDC) were used as a comparison group. RESULTS: Survivors had a mean age of 28.7 years (range, 18.0-44.0 years) and were a mean of 23.1 years from their cancer diagnosis (range, 16.0-33.8 years). In multivariate models, ALL survivors were more likely to not meet CDC recommendations for physical activity [odds ratio (OR), 1.44; 95% confidence interval (95% CI), 1.32-1.57] and more likely to be inactive (OR, 1.74; 95% CI, 1.56-1.94) in comparison with the BRFSS general population. Survivors treated with >20-Gy cranial radiotherapy were at particular risk. Compared with BRFSS participants and adjusted for age, race, and ethnicity, survivors were more likely to not meet CDC recommendations (females: OR, 2.07, 95% CI, 1.67-2.56; males: OR, 1.43, 95% CI, 1.16-1.76) and more likely to be inactive (females: OR, 1.86; 95% CI, 1.50-2.31; males: OR, 1.84; 95% CI, 1.45-2.32). CONCLUSIONS: Long-term survivors of childhood ALL are less likely to meet physical activity recommendations and more likely to report no leisure-time physical activity in the past month. This level of inactivity likely further increases their risk of cardiovascular disease, osteoporosis, and all-cause mortality.

National Health Service Corps staffing and the growth of the local rural non-NHSC primary care physician workforce.

CONTEXT: Beyond providing temporary staffing, National Health Service Corps (NHSC) clinicians are believed by some observers to contribute to the long-term growth of the non-NHSC physician workforce of the communities where they serve; others worry that NHSC clinicians compete with and impede the supply of other local physicians. PURPOSE: To assess long-term changes in the non-NHSC primary care physician workforce of rural underserved counties that have received NHSC staffing support relative to workforce changes in underserved counties without NHSC support. METHODS: Using data from the American Medical Association and NHSC, we compared changes from 1981 to 2001 in non-NHSC primary care physician to population ratios in 2 subsets of rural whole-county health professional shortage areas: (1) 141 counties staffed by NHSC physicians, nurse practitioners, and/or physician assistants during the early 1980s and for many of the years since and (2) all 142 rural health professional shortage area counties that had no NHSC clinicians from 1979 through 2001. FINDINGS: From 1981 to 2001, counties staffed by NHSC clinicians experienced a mean increase of 1.4 non-NHSC primary care physicians per 10,000 population, compared to a smaller, 0.57 mean increase in counties without NHSC clinicians. The finding of greater non-NHSC primary care physician to population mean ratio increase in NHSC-supported counties remained significant after adjusting for baseline county demographics and health care resources (P < .001). The estimated number of "extra" non-NHSC physicians in NHSC-supported counties in 2001 attributable to the NHSC was 294 additional physicians for the 141 supported counties, or 2 extra physicians, on average, for each NHSC-supported county. Over the 20 years, more NHSC-supported counties saw their non-NHSC primary care workforces grow to more than 1 physician per 3,500 persons, but no more NHSC-supported than nonsupported counties lost their health professional shortage area designations. CONCLUSIONS: These data suggest that the NHSC contributed positively to the non-NHSC primary care physician workforce in the rural underserved counties where its clinicians worked during the 1980s and 1990s.

Medical student attitudes to risk taking and self-perceived influence on medical practice.

CONTEXT: Little has been published on medical student risk-taking attitudes and behaviours and whether students think these attributes will affect how they treat patients. OBJECTIVES: Our aims were to assess for an association between risk-taking attitudes and behaviours, such as problematic substance use, self-reported risky behaviours, and self-reported accidents, and to test for an association between risk-taking attitudes and student perceptions of the influence of these attitudes on future clinical practice. METHODS: Three consecutive classes of Year 2 medical students (n=315) completed a self-administered, 29-item questionnaire. Risk-taking attitudes were evaluated using a 6-question, risk-taking scale adapted from the Jackson Personality Inventory (JPI). RESULTS: A significant positive correlation was demonstrated between risk-taking attitudes (JPI) and problematic substance use (r=0.34; P<0.01), self-reported risky behaviours (r=0.47; P<0.01), and self-reported accidents (r=0.33; P<0.01). Students who did not think their attitudes toward risk would affect their clinical decision making scored significantly higher on our measure of risk-taking attitudes (t306=-4.60; P<0.01). Students who did not think that their drinking, drug taking or sexual behaviour would affect how they counselled patients on these matters scored significantly higher on our measure of problematic substance use (t307=-2.51; P=0.01). CONCLUSIONS: Although risk-taking attitudes have been associated with significant differences in clinical decision making among doctors, in our sample students with high risk-taking attitudes and behaviours were significantly less likely than their colleagues to think their attitudes would affect their clinical practice. Implications for medical education are discussed.

A randomized trial of nortriptyline combined with transdermal nicotine for smoking cessation.

BACKGROUND: Smoking cessation rates with current therapy are suboptimal. Tricyclic antidepressants improve cessation rates. We hypothesized that addition of nortriptyline hydrochloride to transdermal nicotine would enhance cessation rates. METHODS: We conducted a randomized, double-blind, placebo-controlled trial at a Department of Veterans Affairs medical center. Subjects were aged 18 to 65 years, smoked 10 or more cigarettes per day, and did not have current major depression. Nortriptyline hydrochloride or matched placebo was started at 25 mg 14 days before quit day, titrated to 75 mg/d as tolerated, and continued for 12 weeks after quit day. Transdermal nicotine (21 mg/d) was started on quit day and continued for 8 weeks. The behavioral intervention consisted of 12 brief, individual visits. Withdrawal symptoms were measured by means of a daily diary, and smoking cessation was defined as self-reported abstinence, expired carbon monoxide level of 9 ppm or less, and a 6-month urine cotinine level less than 50 ng/mL (284 nmol/L). RESULTS: A total of 158 patients were randomized (79 to nortriptyline and 79 to placebo). There was no significant reduction in withdrawal symptoms. The cessation rates at 6 months were 23% (18/79) and 10% (8/79), respectively (absolute difference, 13%; 95% confidence interval, 1.3%-24.5%; P = .052). Nortriptyline caused frequent side effects, including dry mouth (38%) and sedation (20%). CONCLUSIONS: Nortriptyline combined with transdermal nicotine resulted in an increased cessation rate with little effect on withdrawal symptoms. This combination may represent an option for smokers in whom standard therapy has failed.

Specialist physicians providing primary care services in Colorado.

BACKGROUND: There is general consensus that the size of the US physician workforce now exceeds the health care needs of the American public. There is a greater proportion of specialists than primary care physicians, a specialty mix different from that of most other developed countries. METHODS: The Colorado Board of Medical Examiners sent a one-page questionnaire to all physicians licensed to practice in the state. It contained the question: "How many hours in the last week did you provide primary care services, defined as either preventive care, routine physical exams, or treatment of common ailments?" The responses of physicians who reported non-primary-care medical specialties were analyzed with respect to their personal and practice characteristics. RESULTS: Just under half (46.5%) of the 2745 specialist respondents reported having provided primary care services. As a group, however, 27.9% of specialist physicians' direct patient care time was devoted to primary care activities. The amount of primary care services being provided was greater among those not board-certified in their specialties, osteopathic physicians, and specialists spending less time in direct patient care. CONCLUSION: Additional evaluation is needed with a more comprehensive definition of primary care than used in this article, which includes important but difficult-to-measure elements, such as the integration of services, a sustained partnership with patients, and practice in the context of family and community. To the extent possible, this definition should not rely on physician self-definition of which examinations are routine and which ailments are common. However, the contribution of specialists should be considered in future primary care needs assessments, and specialists who experience low demand for their particular specialties may be especially inclined to provide primary care services.

The Balanced Budget Act of 1997 and the financial health of teaching hospitals.

BACKGROUND: We wanted to evaluate the most recent, complete data related to the specific effects of the Balanced Budget Act of 1997 relative to the overall financial health of teaching hospitals. We also define cost report variables and calculations necessary for continued impact monitoring. METHODS: We undertook a descriptive analysis of hospital cost report variables for 1996, 1998, and 1999, using simple calculations of total, Medicare, prospective payment system, graduate medical education (GME), and bad debt margins, as well as the proportion with negative total operating margins. RESULTS: Nearly 35% of teaching hospitals had negative operating margins in 1999. Teaching hospital total margins fell by nearly 50% between 1996 and 1999, while Medicare margins remained relatively stable. GME margins have fallen by nearly 24%, however, even as reported education costs have risen by nearly 12%. Medicare + Choice GME payments were less than 10% of those projected. CONCLUSIONS: Teaching hospitals realized deep cuts in profitability between 1996 and 1999; however, these cuts were not entirely attributable to the Balanced Budget Act of 1997. Medicare payments remain an important financial cushion for teaching hospitals, more than one third of which operated in the red. The role of Medicare in supporting GME has been substantially reduced and needs special attention in the overall debate. Medicare + Choice support of the medical education enterprise is 90% less than baseline projections and should be thoroughly investigated. The Medicare Payment Advisory Commission, which has a critical role in evaluating the effects of Medicare policy changes, should be more transparent in its methods.

The association of Title VII funding to departments of family medicine with choice of physician specialty and practice location.

BACKGROUND: Title VII predoctoral and departmental grants for departments of family medicine are intended to increase the number of family and primary care physicians in the United States and increase the number of practices in rural and underserved communities. This study assessed the relationships of Title VII funding with physicians' choices of practice specialty and location. METHODS: Non-federal direct patient care physicians who graduated from US medical schools from 1981-1993 were identified in the 2000 American Medical Association Masterfile. A grant history file was used to annotate Masterfile records with Title VII funding data for the physicians' 4-year medical school enrollment. Characteristics of the county in which they practice were taken from the Area Resource File. Title VII funding variables were then related to practice specialty and location. RESULTS: Predoctoral training and departmental development funding were strongly related to attainment of each of the Title VII program objectives evaluated. CONCLUSIONS: Title VII has been successful in achieving its stated goals and legislative intent and has had an important role in addressing US physician workforce policy issues.
