Characteristics of Population Health Physicians and the Needs of Healthcare Organizations

INTRODUCTION

Healthcare organizations are transitioning from fee-for-service, volume-based care toward value-based care and the Triple Aim. Physicians have critical roles as leaders and practitioners in this emerging field of population health management; however, the competencies required of these physicians are not well described. The purpose of this study is to explore the approaches of healthcare systems to population health-related functions, the competencies needed, and the characteristics of physicians who lead or staff these functions.

METHODS

Investigators conducted semistructured interviews with a convenience sample of 14 healthcare executives and 15 Preventive Medicine physicians and a focus group with 9 healthcare executives. Interviews and the focus group were recorded, transcribed, and coded. Themes and notable quotes were identified. Data were collected and analyzed in 2019.

RESULTS

Population health was variously defined by the healthcare executives, often naming specific components or activities. The typical population health activities described by healthcare executives (e.g., quality measurement and process improvement) were reported along with the skills of physicians performing these functions (e.g., data analysis, informatics, leadership, business acumen). A total of 2 types of population health physicians were described: the clinician leader and the population health specialist.

CONCLUSIONS

This exploratory study identified several useful competencies for population health physicians in healthcare systems. Findings point to opportunities to promote a more systematic approach to population health and to prepare Preventive Medicine and other physicians for population health management positions.

Multiple COVID-19 Clusters on a University Campus - North Carolina, August 2020

Preventing transmission of SARS-CoV-2, the virus that causes coronavirus disease 2019 (COVID-19), in institutes of higher education presents a unique set of challenges because of the presence of congregate living settings and difficulty limiting socialization and group gatherings. Before August 2020, minimal data were available regarding COVID-19 outbreaks in these settings. On August 3, 2020, university A in North Carolina broadly opened campus for the first time since transitioning to primarily remote learning in March. Consistent with CDC guidance at that time (1,2), steps were taken to prevent the spread of SARS-CoV-2 on campus. During August 3-25, 670 laboratory-confirmed cases of COVID-19 were identified; 96% were among patients aged <22 years. Eighteen clusters of five or more epidemiologically linked cases within 14 days of one another were reported; 30% of cases were linked to a cluster. Student gatherings and congregate living settings, both on and off campus, likely contributed to the rapid spread of COVID-19 within the university community. On August 19, all university A classes transitioned to online, and additional mitigation efforts were implemented. At this point, 334 university A-associated COVID-19 cases had been reported to the local health department. The rapid increase in cases within 2 weeks of opening campus suggests that robust measures are needed to reduce transmission at institutes of higher education, including efforts to increase consistent use of masks, reduce the density of on-campus housing, increase testing for SARS-CoV-2, and discourage student gatherings.

Building a Viable Weight Management Program in a Patient-Centered Medical Home

BACKGROUND AND OBJECTIVES

The growing prevalence of obesity in the United States and globally highlights the need for innovative strategies to provide obesity treatment in primary care settings. This report describes and evaluates the Weight Management Program (WMP), an interprofessional program in an academic family medicine clinic delivering intensive behavioral therapy (IBT) following evidenced-based guidelines.

METHODS

We extracted WMP participant health data from the electronic health record and evaluated retrospectively. Eligible participants completed at least four WMP visits and had a baseline weight, blood pressure, and hemoglobin A1c (HbA1c) recorded within 1 year prior to their first visit. Paired t tests were used to assess changes in, weight, HbA1c and systolic and diastolic blood pressures from baseline.

RESULTS

WMP counseled 673 patients over 3,895 visits from September 2015 to June 2019. Of these, 186 met eligibility criteria (at least four visits), with a median of eight visits (mean=11.3, SD=8.1). Participants saw an average weight decrease during program participation of 9.7 lbs (P&lt;.001), an average decrease in HbA1c of 0.2 points (P=.004), and an average blood pressure reduction of 2.8 mmHg systolic (P=.002) and 1.9 mmHg diastolic (P=.03). One-third of participants (n=60) achieved clinically significant weight loss (&gt;5%) at 18 months. The program has become financially sustainable through billing for preventive counseling services and a $125 out-of-pocket enrollment fee.

CONCLUSIONS

WMP provides one model for primary care practices to develop a financially sustainable and evidence-based behavioral therapy weight management program for their patients with obesity. Future work will include assessment of longer-term program benefits, quality metrics, and health care costs.

Using a RE-AIM framework to identify promising practices in National Diabetes Prevention Program implementation

BACKGROUND

The National Diabetes Prevention Program (National DPP) is rapidly expanding in an effort to help those at high risk of type 2 diabetes prevent or delay the disease. In 2012, the Centers for Disease Control and Prevention funded six national organizations to scale and sustain multistate delivery of the National DPP lifestyle change intervention (LCI). This study aims to describe reach, adoption, and maintenance during the 4-year funding period and to assess associations between site-level factors and program effectiveness regarding participant attendance and participation duration.

METHODS

The Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) framework was used to guide the evaluation from October 2012 to September 2016. Multilevel linear regressions were used to examine associations between participant-level demographics and site-level strategies and number of sessions attended, attendance in months 7-12, and duration of participation.

RESULTS

The six funded national organizations increased the number of participating sites from 68 in 2012 to 164 by 2016 across 38 states and enrolled 14,876 eligible participants. By September 2016, coverage for the National DPP LCI was secured for 42 private insurers and 7 public payers. Nearly 200 employers were recruited to offer the LCI on site to their employees. Site-level strategies significantly associated with higher overall attendance, attendance in months 7-12, and longer participation duration included using self-referral or word of mouth as a recruitment strategy, providing non-monetary incentives for participation, and using cultural adaptations to address participants' needs. Sites receiving referrals from healthcare providers or health systems also had higher attendance in months 7-12 and longer participation duration. At the participant level, better outcomes were achieved among those aged 65+ (vs. 18-44 or 45-64), those who were overweight (vs. obesity), those who were non-Hispanic white (vs. non-Hispanic black or multiracial/other races), and those eligible based on a blood test or history of gestational diabetes mellitus (vs. screening positive on a risk test).

CONCLUSIONS

In a time of rapid dissemination of the National DPP LCI the findings of this evaluation can be used to enhance program implementation and translate lessons learned to similar organizations and settings.

Alignment of Preventive Medicine Physicians' Residency Training With Professional Needs

Preventive medicine (PM) physicians promote population-based approaches to health care with training that emphasizes public health, epidemiology, and policy. PM physicians use these skills in varied, often nonclinical, practice settings. PM career diversity challenges educators when designing residency curricula. Input from PM physicians about workforce environments is needed to ensure that residency requirements match skills needed post-residency. Graduates of one PM residency were sent a cross-sectional survey in 2016. Questions included professional experience, importance of 18 Accreditation Council for Graduate Medical Education sub-competencies and 13 leadership/management skills to current position, and residency training adequacy in those sub-competencies/skills. Responses were rated on 3-point Likert scales. Analyses were completed in 2017. Pearson's chi-square tests examined relationships between position type (academic/government) and perception of competencies' importance and training adequacy. Eighty PM physicians responded (46%): 44% worked in academia and 25% in federal/state/local government. Half (53%) were PM board certified. A total of 88% completed clinical residency prior to PM. Thirteen of 18 competencies were important to work, and respondents felt well trained in 16 of 18 competencies. Respondents did not feel well trained in emergency preparedness and surveillance systems during residency and their opinions about the importance of these sub-competencies varied based on where they worked. Respondents rated all 13 leadership/management skills as important, but reported inadequate residency training. In conclusion, respondents rated most Accreditation Council for Graduate Medical Education sub-competencies as important to current work and felt well trained, indicating good alignment between residency training and professional needs. Respondents also reported leadership/management training deficiencies. PM residencies might consider incorporating formal leadership training into curricula.

Scaling Up Diabetes Prevention Programs in North Carolina: Perceptions of Demand From Potential Program Recipients and Providers

Purpose

The purpose of this study was to assess factors that influence demand for the Diabetes Prevention Program (DPP) from the perspectives of potential program participants and providers.

Methods

A qualitative study guided by a conceptual framework was conducted with potential DPP participants and potential DPP providers. Five focus groups with potential participants (n = 37) and key informant interviews with potential providers (n = 14) were conducted in community settings across North Carolina.

Results

Although providers considered prediabetes to be an important health problem, potential DPP participants expressed less urgency related to a diagnosis of prediabetes. Potential participants felt that they were more likely to adopt diabetes prevention programs if affordable and convenient. For potential program providers, funding, collaboration, and staff support were key considerations for DPP adoption. Providers were supportive of DPP features; however, there was concern from both stakeholders on retention in a 16-week program. Both groups cited transportation, cost, and health insurance reimbursement as existing barriers to the uptake of these programs.

Conclusion

This qualitative study highlights important considerations for scaling up diabetes prevention programs in community settings, including what constraints agencies face in adopting programs, the perceived demand and programmatic needs for these services by customers, and the need for improving patient education on prediabetes. This implementation science study allows us to increase the potential to scale up and sustain diabetes prevention programs that fit available resources and customer needs.

Evaluation of a Quality Improvement Resource for Public Health Practitioners

OBJECTIVES

Quality improvement is a critical mechanism to manage public health agency performance and to strengthen accountability for public funds. The objective of this study was to evaluate a relatively new quality improvement resource, the Public Health Quality Improvement Exchange (PHQIX), a free online communication platform dedicated to making public health quality improvement information accessible to practitioners.

METHODS

We conducted an internet-based survey of registered PHQIX users (n = 536 respondents) in 2013 and key informant interviews with PHQIX frequent users (n = 21) in 2014, in the United States. We assessed use of the PHQIX website, user engagement and satisfaction, communication and knowledge exchange, use of information, and impact on quality improvement capacity and accreditation readiness.

RESULTS

Of 462 respondents, 369 (79.9%) browsed quality improvement initiatives, making it the most commonly used site feature, and respondents described PHQIX as a near-unique source for real-world quality improvement examples. Respondents were satisfied with the quality and breadth of topics and relevance to their settings (average satisfaction scores, 3.9-4.1 [where 5 was the most satisfied]). Of 407 respondents, 237 (58.2%) said that they had put into practice information learned on PHQIX, and 209 of 405 (51.6%) said that PHQIX had helped to improve quality improvement capacity. Fewer than half of respondents used the commenting function, the Community Forum, and the Ask an Expert feature.

CONCLUSIONS

Findings suggest that PHQIX, particularly descriptions of the quality improvement initiatives, is a valued resource for public health practitioners. Users reported sharing information with colleagues and applying what they learned to their own work. These findings may relate to other efforts to disseminate quality improvement knowledge.

Measuring public health practice and outcomes in chronic disease: a call for coordination

A strategic opportunity exists to coordinate public health systems and services researchers' efforts to develop local health department service delivery measures and the efforts of divisions within the Centers for Disease Control and Prevention's National Center for Chronic Disease Prevention and Health Promotion (NCCDPHP) to establish outcome indicators for public health practice in chronic disease. Several sets of outcome indicators developed by divisions within NCCDPHP and intended for use by state programs can be tailored to assess outcomes of interventions within smaller geographic areas or intervention settings. Coordination of measurement efforts could potentially allow information to flow from the local to the state to the federal level, enhancing program planning, accountability, and even subsequent funding for public health practice.

Linkages between clinical practices and community organizations for prevention: a literature review and environmental scan

CONTEXT

A literature review and environmental scan were conducted to develop a framework for interventions that utilize linkages between clinical practices and community organizations for the delivery of preventive services, and to identify and characterize these efforts.

EVIDENCE ACQUISITION

A search was made of four major health services and social science electronic databases and an Internet search was conducted to identify examples of linkage interventions in the areas of tobacco cessation, obesity, nutrition, and physical activity.

EVIDENCE SYNTHESIS

In all, 49 interventions were identified, of which 18 examples described their evaluation methods or reported any intervention outcomes. Few conducted evaluations that were rigorous enough to capture changes in intermediate or long-term health outcomes. Outcomes in these evaluations were primarily patient-focused and did not include organizational or linkage characteristics.

CONCLUSIONS

An attractive option to increase the delivery of preventive services is to link primary care practices to community organizations; evidence is not yet conclusive, however, that such linkage interventions are effective. Findings provide recommendations to researchers and organizations that fund research, and call for a framework and metrics to study linkage interventions.

Public health case studies in diabetes prevention and control: innovation, partnerships, and funding

BACKGROUND

In 2006, we conducted case studies of 4 North Carolina local health departments (LHDs) that scored highly on an index of diabetes prevention and control performance, to explore characteristics that may serve as barriers or facilitators of diabetes prevention and control services.

METHODS

Case studies involving in-depth interviews were conducted at 4 LHDs. Sites were selected on the basis of 2 variables, known external funding for diabetes services and population size, that were associated with performance in diabetes prevention and control in a 2005 survey of all North Carolina LHDs. Fourteen interviews (individual and group) were conducted among 17 participants from the 4 LHDs. The main outcome measures were LHD characteristics that facilitate or hinder the performance of diabetes programs and services.

RESULTS

Interviews revealed that all 4 high-performing LHDs had received some sort of funding from a source external to the LHD. Case study participants indicated that barriers to additional service delivery included low socioeconomic status of the population and lack of financial resources. Having a diabetes self-management education program that was recognized by the American Diabetes Association appeared to be a facilitator of diabetes services provision. Other facilitators were leadership and staff commitment, which appeared to facilitate the leveraging of partnerships and funding opportunities, leading to enhanced service delivery.

LIMITATIONS

The small number of LHDs participating in the study and the cross-sectional study design were limitations.

CONCLUSION

Leadership, staff commitment, partnership leveraging, and funding appear to be associated with LHD performance in diabetes prevention and control services. These factors should be further studied in future public health systems and services research.

The diabetes primary prevention initiative interventions focus area: a case study and recommendations

BACKGROUND

In 2005, CDC began the Diabetes Primary Prevention Initiative Interventions Focus Area (DPPI-IFA), which funded five state Diabetes Prevention and Control Programs (DPCPs) to translate diabetes primary prevention trials into real-world settings by developing and implementing a framework for state-level diabetes primary prevention.

PURPOSE

The purpose of this case study, conducted in 2007, was to describe DPPI-IFA implementation, including facilitators and challenges to the initiative.

METHODS

Case studies of the five DPCPs in the DPPI-IFA involving site visits with key informant interviews of state staff and partners and archival record collection.

RESULTS

Partners recruited for DPPI-IFA activities included local or state public health agencies (three of five DPCPs); regional or state nonprofit organizations (five DPCPs); businesses or employers (three DPCPs); and healthcare organizations (four DPCPs). The DPCPs implemented a variety of interventions in three main domains: diabetes primary prevention and prediabetes awareness, screening activities and lifestyle interventions, and prediabetes-related health policy efforts. Preliminary outcomes are described at the individual and organization/partnership levels. Results suggest the importance of utilizing preexisting partnerships to extend work into diabetes prevention, providing even small amounts of funding to partners, and prior program planning for diabetes prevention. Challenges for the DPPI-IFA included recruiting participants, establishing links with providers to obtain diagnostic testing for people screened for prediabetes, and offering a lifestyle intervention.

CONCLUSIONS

The DPPI-IFA represents a unique effort by state public health programs in the translation of diabetes primary prevention trials into real-world settings. The experiences of the DPPI-IFA programs offer valuable lessons for future community-based diabetes prevention initiatives, especially regarding the need to strengthen clinical-community partnerships for referral of people with prediabetes to evidence-based lifestyle programs.

Systematic review: enhancing the use and quality of colorectal cancer screening

BACKGROUND

National guideline groups recommend screening and discussion of screening options for persons at average risk for colorectal cancer (CRC). However, emerging evidence suggests that CRC screening is simultaneously underused, overused, and misused and that adequate patient-provider discussions about screening are infrequent.

PURPOSE

To summarize evidence on factors that influence CRC screening and strategies that increase the appropriate use and quality of CRC screening and CRC screening discussions.

DATA SOURCES

MEDLINE, the Cochrane Library, and the Cochrane Central Register of Controlled Trials were searched for English-language publications describing studies conducted in the United States from January 1998 through September 2009.

STUDY SELECTION

Two reviewers independently selected studies that addressed the study questions and met eligibility criteria.

DATA EXTRACTION

Information on study design, setting, intervention, outcomes, and quality were extracted by one reviewer and double-checked by another. Reviewers assigned a strength-of-evidence grade for intervention categories by using criteria plus a consensus process.

DATA SYNTHESIS

Reviewers found evidence of simultaneous underuse, overuse, and misuse of CRC screening as well as inadequate clinical discussions about CRC screening. Several patient-level factors were independently associated with lower screening rates, including having low income or less education, being uninsured, being Hispanic or Asian, being less acculturated into the United States, or having limited access to care. Evidence that interventions that included patient reminders or one-on-one interactions (that is, between patients and nonphysician clinic staff), eliminated structural barriers (for example, simplifying access to fecal occult blood test cards), or made system-level changes (for example, using systematic screening as opposed to opportunistic screening) were effective in enhancing use of CRC screening was strong. Evidence on how best to enhance discussions about CRC screening options is limited. No studies focused on reducing overuse, and very few focused on misuse.

LIMITATIONS

Reporting and publication bias may have affected our findings. The independent effect of individual elements of multicomponent interventions was often uncertain.

CONCLUSION

Although CRC screening is underused overall, important problems of overuse and misuse also exist. System- and policy-level interventions that target vulnerable populations are needed to reduce underuse. Interventions aimed at reducing barriers by making the screening process easier are likely to be effective. Studies aimed at reducing overuse and misuse and at enhancing the quality and frequency of discussions about CRC screening options are needed.

Enhancing the use and quality of colorectal cancer screening

OBJECTIVES

To conduct a systematic review of the use and quality (including underuse, overuse, and misuse) of appropriate colorectal cancer (CRC) screening, including factors associated with screening, effective interventions to improve screening rates, current capacity, and monitoring and tracking the use and quality. Trends in the use and quality of CRC screening tests is also presented.

DATA SOURCES

We searched MEDLINE, the Cochrane Library, and the Cochrane Central Trials Registry, supplemented by handsearches, for studies published in English from January 1998 through September 2009.

REVIEW METHODS

We used standard Evidence-based Practice Center methods of dual review of abstracts, full text articles, abstractions, quality rating, and quality grading. We resolved disagreements by consensus.

RESULTS

We found multiple problems of underuse, overuse, and misuse of CRC screening. We identified a total of 116 articles for inclusion into the systematic review, including a total of 72 studies qualified for inclusion for key question (KQ) 2, 21 for KQ 3, 12 for KQ 4, and 8 for KQ 5. A number of patient-level factors are associated with lower screening rates, including having low income or less education, being uninsured or of Hispanic or Asian descent, not being acculturated into the United States, and having less or reduced access to care. Being insured, of higher income or education, and non-Hispanic white, participating in other cancer screenings, having a family history of CRC or personal history of another cancer, as well as receiving a physician recommendation to be screened, are associated with higher screening rates. Interventions that effectively increased CRC screening with high strength of evidence include patient reminders, one-on-one interactions, eliminating structural barriers, and system-level changes. The largest magnitude of improvement came from one-on-one interactions and eliminating barriers. Purely educational small-media interventions do not improve screening rates. Evidence is mixed for decision aids, although certain designs may be effective. No studies tested interventions to reduce overuse or misuse of CRC screening. We found no studies that assessed monitoring systems for underuse, overuse, and misuse of CRC screening. Modeling studies, using various assumptions, show that if the United States were to adopt a colonoscopy-only approach to CRC screening and everyone were to agree to be screened in this way, it is likely that colonoscopy capacity would need to be substantially increased.

CONCLUSIONS

Both CRC screening and patient-physician discussions of CRC screening are underused, and important problems of overuse and misuse also exist. Some interventions hold promise for improvement. The research priority is to design and test interventions to increase screening and CRC screening discussions, building on the effective approaches identified in this review, and tailored to specific population needs. In addition, new interventions to reduce overuse and misuse should be designed and tested, along with studies of ongoing monitoring systems that are linked to feedback and continued improvement efforts.

Assessing local health department performance in diabetes prevention and control--North Carolina, 2005

INTRODUCTION

To improve the public health system's ability to prevent and control chronic diseases, we must first understand current practice and develop appropriate strategies for measuring performance. The objectives of this study were to measure capacity and performance of local health departments in diabetes prevention and control and to investigate characteristics associated with performance.

METHODS

In 2005, we conducted a cross-sectional mailed survey of all 85 North Carolina local health departments to assess capacity and performance in diabetes prevention and control based on the 10 Essential Public Health Services and adapted from the Local Public Health System Performance Assessment Instrument. We linked survey responses to county-level data, including data from a national survey of local health departments.

RESULTS

Local health departments reported a median of 0.05 full-time equivalent employees in diabetes prevention and 0.1 in control. Performance varied across the 10 Essential Services; activities most commonly reported included providing information to the public and to policy makers (76%), providing diabetes education (58%), and screening (74%). The mean score on a 10-point performance index was 3.5. Characteristics associated with performance were population size, health department size and accreditation status, and diabetes-specific external funding. Performance was not better in localities where the prevalence of diabetes was high or availability of primary care was low.

CONCLUSION

Most North Carolina local health departments had limited capacity to conduct diabetes prevention or control programs in their communities. Diabetes is a major cause of illness and death, yet it is neglected in public health practice. These findings suggest opportunities to enhance local public health practice, particularly through targeted funding and technical assistance.

Screening for diabetes in an African-American community: the Project DIRECT experience

AIM

To report the results of a community-based screening program associated with Project DIRECT, a multiyear diabetes mellitus prevention and control project targeting African-American residents of southeast Raleigh, NC.

METHODS

Between December 1996 and June 1999, 183 screening events took place in community settings. Screening was by capillary glucose concentration. Participants with a positive screen were referred for confirmatory testing and physician follow-up.

MAIN RESULTS

Risk factors for diabetes were prevalent, including ethnic minority race (88.2%), obesity (45.6%), and family history of diabetes (41.7%). In all, 197 personshad an elevated screening result; the prevalence of diabetes in the screened population that underwent follow-up testiing was 1.7%. Despite persistent tracking efforts, 28% of the persons with a high screening test received no final diagnosis

CONCLUSIONS

In this community-based screening program targeted to high-risk African Americans, risk factors for diabetes were common, but new cases of undiagnosed diabetes among participants were uncommon. Intensive follow-up for persons with high screening values is necessary but difficult to achieve. Our results support national recommendations against community-based screening; opportunistic screening for diabetes in clinical settings is likely a more effective use of resources.

Quality care improvement program in a community-based participatory research project: example of Project DIRECT

A continuous quality care improvement program (CQIP) was built into Project DIRECT (Diabetes Interventions Reaching and Educating Communities Together) to improve providers' patterns of diabetes care and patients' glycemic control. Project DIRECT consisted of a comprehensive program aimed at reducing the burden of diabetes in the vulnerable high-risk African-American population of southeast Raleigh, NC. Forty-seven providers caring for this target population of adult diabetes patients were included in this quasi-experimental study. At the initial session, providers learned about the CQIP components, completed a planning worksheet, and chose a CQIP coordinator. Educational events included continuing education in practices and through conferences by experts, and guideline distribution. Follow-up was accomplished through phone calls and visits. Effectiveness was measured by a change in prevalence of selected patterns of care abstracted from 1,006 medical charts. Appropriate statistical methods were used to account for the cluster design and repeated measures. At the fourth follow-up year, approximately 40% of providers still participated in the program. Among the providers who stayed in the program for the whole study period, most selected quality care patterns showed significant upward trends. Glycemic control indicators did not change, however, despite an increased number of hemoglobin A1c tests per year. A diabetes CQI program can be effectively implemented in a community setting. Improved performance measures were not associated with improved outcomes. These results suggest that a patient-centered component should reinforce the provider-centered component.

Barriers to cancer pain management: home-health and hospice nurses and patients

GOALS

Undertreatment of cancer pain remains a major health-care problem. We utilized focus groups of hospice and home-health nurses and patients to elucidate factors contributing to inadequate pain management and to generate solutions for closing the gap between the current reality and optimal pain management.

PATIENTS AND METHODS

Focus groups were conducted among hospice and home-health-care nurses (two groups; n=22) and patients (six groups; n=54) using a standardized question guide. Audiotapes were transcribed and analyzed using NUD*IST software. Themes discovered among patients and nurses were analyzed for similarities and differences.

MAIN RESULTS

Of 22 participants in the two home-health and hospice nurses focus groups, all were white women, the average age was 43 (range 29-64) years, and the average number of years in nursing was 21 (range 8-47) years. Of 54 participants in the six cancer patient focus groups, 80% were women, the average age was 54 (range 25-76) years, and 76% were white. Fifty-four percent of patients reported a history of pain associated with their cancer, and almost 30% had pain that they rated as 8 or higher on the pain scale. Barriers to adequate pain management fell into four categories: fears; attitudes, beliefs, and values; patient and provider behaviors; and structural barriers. Patients and nurses reported similar barriers to pain management; however, patients identified more barriers related to provider behavior and structure of the health care system.

CONCLUSIONS

This study identified several barriers to cancer pain control not previously identified in the literature. Strategies to improve cancer pain control are suggested.

Caring for the underserved: current practice of alumni of the National Health Service Corps

The objective of this study was to examine the number and characteristics of National Health Service Corps (NHSC) alumni who currently practice with an underserved population. The study design was a cross-sectional survey mailed in 1998 to a sample of 2,160 alumni. The response rate was 58.9 percent; overall, 52.5 percent of respondents reported currently working with the underserved. In bivariate analyses, retention in practice with the underserved was associated with several clinician and service experience variables. In a logistic regression model, higher initial desire to work with the underserved, older age, job satisfaction, and higher salary were associated with current service. The authors conclude that more than half of the NHSC alumni responding to the survey reported working with an underserved population in 1998. Associations between clinician and service experience characteristics and retention in practice with the underserved can inform policy and research to improve retention.

Provision of care to the underserved populations by National Health Service Corps alumni dentists

OBJECTIVE

This study examined factors associated with dentists continuing to provide care to the underserved populations beyond their National Health Service Corps (NHSC) obligation period.

METHODS

Self-administered questionnaires were mailed in 1998 to 404 dentists who had completed their service obligation between 1980 and 1997. The outcome variable was dentist self-report of continuing to work with the underserved population past NHSC obligation.

RESULTS

Among 249 respondents (62% response rate), 46 percent of alumni dentists continued to work with an underserved population. Multivariate analyses found that being an African American (odds ratio [OR] = 3.2), higher final salary during the NHSC assignment (OR = 1.2), and higher altruistic motivation to work with the underserved populations prior to entering NHSC (OR = 1.1) were significantly associated with continued service to the underserved populations.

CONCLUSIONS

A small number of factors were associated with alumni NHSC dentists' decisions to continue to provide care for the underserved populations. Targeting African-American students and students interested in caring for the underserved may improve the long-term commitment of dentists to provide care for the underserved populations. Attention will also need to be given to increased salary as a potential intervention to increase the numbers of dentists who continue to serve the underserved populations.

Quality of care for uninsured patients with diabetes in a rural area

OBJECTIVE

We compared quality of care for uninsured patients with diabetes in private physician offices and community/migrant health centers (C/MHCs).

RESEARCH DESIGN AND METHODS

We conducted a cross-sectional medical record review in a convenience sample of eight physician offices and three C/MHC sites in rural North Carolina. Billing systems generated lists of self-pay patients with diabetes. Abstraction of the medical records (n = 142) yielded data on process and intermediate outcome measures of diabetes care, which were derived from the Diabetes Quality Improvement Project.

RESULTS

Medical records of patients in C/MHCs demonstrated higher rates on four of six process measures of quality of care, including measurement of HbA(1c) (98 vs. 75%; P < 0.001), cholesterol (82 vs. 51%; P < 0.001), and urine protein (90 vs. 25%; P < 0.001). Nonsignificant trends in documented eye examinations and the intermediate outcome of blood pressure control were found in medical records of C/MHC patients. No differences were seen in the intermediate outcomes of glucose or lipid control. Notable differences in provider type, time since training, and use of flow sheets were found.

CONCLUSIONS

In our sample, uninsured patients with diabetes in C/MHCs had higher quality of care as suggested by higher rates of processes of care. Outcomes were similar in the two settings and well below targets. Further work is required to replicate these findings and to understand which features of C/MHCs may facilitate quality care for the uninsured and are replicable in other settings.
