Overall Work and Practice Satisfaction of Licensed Clinical Social Workers in the National Health Service Corps Loan Repayment Program.

Little is known about the job satisfaction of licensed clinical social workers (LCSWs) participating in the National Health Service Corps (NHSC) federal Loan Repayment Program (LRP). Employee satisfaction in organizations is important for organizational well-being and to decrease turnover. A satisfied NHSC LCSW workforce is also important given the array of services it provides, especially in rural and underserved areas. This study examined the work satisfaction of 386 LCSWs participating in the NHSC LRP in 21 states. Rural upbringing, being older than 40 years, and a higher salary were significantly associated with overall work and practice satisfaction. In addition, satisfaction with administration, staff and the practices' linkages to other health providers, the mission of the practice, and connection with patients were strongly associated with overall work and practice satisfaction. To our knowledge, this is the first study to examine the work and practice satisfaction of LCSWs participating in the NHSC LRP, and our findings have the potential to inform the NHSC's strategies in managing and retaining LCSWs.

Circulating palmitoleic acid is an independent determinant of insulin sensitivity, beta cell function and glucose tolerance in non-diabetic individuals: a longitudinal analysis.

AIMS/HYPOTHESIS: Experimental studies suggest that the fatty acid palmitoleate may act as an adipocyte-derived lipid hormone (or 'lipokine') to regulate systemic metabolism. We investigated the relationship of circulating palmitoleate with insulin sensitivity, beta cell function and glucose tolerance in humans. METHODS: Plasma NEFA concentration and composition were determined in non-diabetic individuals from the Relationship between Insulin Sensitivity and Cardiovascular disease (RISC) study cohort at baseline (n = 1234) and after a 3 year follow-up (n = 924). Glucose tolerance, insulin secretion and beta cell function were assessed during an OGTT. Whole-body insulin sensitivity was measured by a hyperinsulinaemic-euglycaemic clamp (M/I) and OGTT (oral glucose insulin sensitivity index [OGIS]). The liver insulin resistance index was calculated using clinical and biochemical data. Body composition including fat mass was determined by bioelectrical impedance. RESULTS: Circulating palmitoleate was proportional to fat mass (r = 0.21, p < 0.0001) and total NEFA levels (r = 0.19, p < 0.0001). It correlated with whole-body insulin sensitivity (M/I: standardised regression coefficient [std. ß] = 0.16, p < 0.0001), liver insulin resistance (std. ß = -0.14, p < 0.0001), beta cell function (potentiation: std. ß = 0.08, p = 0.045) and glucose tolerance (2 h glucose: std. ß = -0.24, p < 0.0001) after adjustment for age, sex, BMI, adiposity and other NEFA. High palmitoleate concentrations prevented the decrease in insulin sensitivity associated with excess palmitate (p = 0.0001). In a longitudinal analysis, a positive independent relationship was observed between changes in palmitoleate and insulin sensitivity over time (std. ß = 0.07, p = 0.04). CONCLUSIONS/INTERPRETATION: We demonstrated that plasma palmitoleate is an independent determinant of insulin sensitivity, beta cell function and glucose tolerance in non-diabetic individuals. These results support the role of palmitoleate as a beneficial lipokine released by adipose tissue to prevent the negative effects of adiposity and excess NEFA on systemic glucose metabolism.

Spatial mode detection by frequency upconversion.

The efficient creation and detection of spatial modes of light has become topical of late, driven by the need to increase photon bit-rates in classical and quantum communications. Such mode creation/detection is traditionally achieved with tools based on linear optics. Here we put forward a new spatial mode detection technique based on the nonlinear optical process of sum-frequency generation. We outline the concept theoretically and demonstrate it experimentally with intense laser beams carrying orbital angular momentum and Hermite-Gaussian modes. Finally, we show that the method can be used to transfer an image from the infrared band to the visible, which implies the efficient conversion of many spatial modes.

An evaluation of state-based support-for-service programs targeting nurse faculty.

AIM: The aim of the study was to assess how state-based support-for-service (SFS) programs are used by deans and directors of nursing programs and to evaluate their perceived impact. BACKGROUND: Given projected nurse faculty shortages, stakeholders are looking for ways to address the maldistribution and shortage of nurse faculty. One state-level strategy is the implementation of loan repayment and scholarship programs, which incentivize individuals with, or currently pursuing, graduate degrees to become or remain nurse faculty. METHOD: This study used a mixed-method and multilevel approach to assess the impact of SFS programs in seven states. RESULTS: Programs are perceived to affect both recruitment and retention of faculty and play a role in increasing the educational qualifications of current nurse faculty. CONCLUSION: Nurse educators need to be aware of SFS programs and how best to use them to support nurse faculty.

Design and evaluation of a prelicensure interprofessional course on improving care transitions.

Effective management of care transitions for older adults require the coordinated expertise of an interprofessional team. Unfortunately, different health care professions are rarely educated together or trained in teamwork skills. To address this issue, a team of professionally diverse faculty from the Duke University Geriatric Education Center designed an interprofessional course focused on improving transitions of care for older adults. This innovative prelicensure course provided interactive teaching sessions designed to promote critical thinking and foster effective communication among health care professionals, caregivers, and patients. Students were assessed by in-class and online participation, performance on individual assignments, and team-based proposals to improve care transitions for older patients with congestive heart failure. Twenty students representing six professions completed the course; 18 completed all self-efficacy and course evaluation surveys. Students rated their self-efficacy in several domains before and after the course and reported gains in teamwork skills (p < .001), transitions of care (p < .001), quality improvement (p < .001) and cultural competence (p < .001). Learner feedback emphasized the importance of enthusiastic and well-prepared faculty, interactive learning experiences, and engagement in relevant work. This course offers a promising approach to shifting the paradigm of health professions education to empower graduates to promote quality improvement through team-based care.

Physician assistants and nurse practitioners in the National Health Service Corps.

OBJECTIVES: This study describes the experiences of physician assistants (PAs) and nurse practitioners (NPs) in the National Health Service Corps' (NHSC) loan repayment program in 2010. METHODS: In 2011, a stratified random sample of NHSC clinicians was surveyed. Data from the 148 PA and 137 NP respondents were analyzed (52.4% response rate). RESULTS: PAs were younger than NPs (mean age 31 versus 35 years), less often female (68% versus 91%), and more often carried educational debt over $100,000 (56% versus 24%). Both groups were serving in states familiar to them and within communities where they felt accepted. The groups were generally satisfied on most measures of work, with PAs more satisfied than NPs on some measures. CONCLUSION: The NHSC's PAs and NPs are well matched to communities and satisfied with their work. Maximizing their NHSC experiences and retention requires recognizing their differences in demographics, debt, and areas of job satisfaction.

Implementing quantum walks using orbital angular momentum of classical light.

We present an implementation scheme for a quantum walk in the orbital angular momentum space of a laser beam. The scheme makes use of a ring interferometer, containing a quarter-wave plate and a q plate. This setup enables one to perform an arbitrary number of quantum walk steps. In addition, the classical nature of the implementation scheme makes it possible to observe the quantum walk evolution in real time. We use nonquantum entanglement of the laser beam's polarization with its orbital angular momentum to implement the quantum walk.

Design and Evaluation of an Interprofessional Preceptor Development Mini-Fellowship Program.

INTRODUCTION: Health professions preceptors require skills and knowledge to effectively meet the educational needs of interprofessional students in clinical environments. We implemented a mini-fellowship program to enhance the knowledge, skills, and self-efficacy of preceptors teaching students and applying quality improvement (QI) methods across disciplines and patient care settings. METHOD: The design, implementation, and evaluation of the program were informed by the faculty development literature, principles of adult learning, and preceptor needs. The 3-day program included workshops on curriculum design, clinical teaching methods, QI, social determinants of health, cultural humility, and interprofessional teamwork. Quantitative and qualitative evaluation methods were used including preprogram and postprogram knowledge and self-efficacy surveys, along with end-of-session and program evaluations. RESULTS: Five annual cohorts involving 41 preceptors with varied demographics, professions, and clinical practices completed the mini-fellowship program. Participants' percentage of items answered correctly on a QI knowledge test increased from 79.2% (pretest) to 85.5% (post-test), a gain of 6.3% (90% CI: 2.9-9.7%; P < .003). The average QI self-efficacy scores improved from 2.64 to 3.82, a gain of 1.18 points on a five-point scale (P < .001). The average education/teaching self-efficacy increased from 2.79 to 3.80 on a five-point scale (P < .001). Ultimately, 94% would recommend the program to other preceptors. DISCUSSION: An interprofessional preceptor development program designed to train clinicians to effectively teach in the clinical setting and to conduct QI projects with students was achievable and effective. This program can serve as a model for academic centers charged with training future health care workers and supporting their community-based preceptors' training needs.

Quantum transport of high-dimensional spatial information with a nonlinear detector.

Information exchange between two distant parties, where information is shared without physically transporting it, is a crucial resource in future quantum networks. Doing so with high-dimensional states offers the promise of higher information capacity and improved resilience to noise, but progress to date has been limited. Here we demonstrate how a nonlinear parametric process allows for arbitrary high-dimensional state projections in the spatial degree of freedom, where a strong coherent field enhances the probability of the process. This allows us to experimentally realise quantum transport of high-dimensional spatial information facilitated by a quantum channel with a single entangled pair and a nonlinear spatial mode detector. Using sum frequency generation we upconvert one of the photons from an entangled pair resulting in high-dimensional spatial information transported to the other. We realise a d = 15 quantum channel for arbitrary photonic spatial modes which we demonstrate by faithfully transferring information encoded into orbital angular momentum, Hermite-Gaussian and arbitrary spatial mode superpositions, without requiring knowledge of the state to be sent. Our demonstration merges the nascent fields of nonlinear control of structured light with quantum processes, offering a new approach to harnessing high-dimensional quantum states, and may be extended to other degrees of freedom too.

North Carolina's mental health workforce: unmet need, maldistribution, and no quick fixes.

BACKGROUND: Recent data show a maldistribution of psychiatrists in North Carolina and critical shortages in some areas. However, only 11 entire counties have official mental health professional shortage designation. METHODS: This paper presents estimates of the adequacy of the county-level mental health professional workforce. These estimates build on previous work in 4 ways: They account for mental health need as well as provider supply, capture adequacy of the prescriber and nonprescriber workforce, consider mental health services provided by primary care providers, and account for travel across county lines by providers and consumers. Workforce adequacy is measured at the county level by the percentage of rieed for mental health visits that is met by the current supply of prescribers and nonprescribers. RESULTS: Ninety-five of North Carolina's 100 counties have unmet need for prescribers. In contrast, only 7 have unmet need for nonprescribers, and these counties have inadequate numbers of prescribers as well. To eliminate the deficit under current national patterns of care, the state would need about 980 more prescribers. LIMITATIONS: Data limitations constrain findings to focus on percentage of met need rather than supplying exact counts of additional professionals needed. Estimates do not distinguish between public and private sectors of care, nor do they embody a standard of care. CONCLUSIONS: North Carolina is working to develop its mental health prescriber workforce. The Affordable Care Act provides new opportunities to develop the mental health workforce, innovative practices involving an efficient mix of professionals, and financing mechanisms to support them.

Experiences of Safety-Net Practice Clinicians Participating in the National Health Service Corps During the COVID-19 Pandemic.

OBJECTIVES: The impact of the COVID-19 pandemic has been particularly harsh for low-income and racial and ethnic minority communities. It is not known how the pandemic has affected clinicians who provide care to these communities through safety-net practices, including clinicians participating in the National Health Service Corps (NHSC). METHODS: In late 2020, we surveyed clinicians who were serving in the NHSC as of July 1, 2020, in 20 states. Clinicians reported on work and job changes and their current well-being, among other measures. Analyses adjusted for differences in subgroup response rates and clustering of clinicians within practices. RESULTS: Of 4263 surveyed clinicians, 1890 (44.3%) responded. Work for most NHSC clinicians was affected by the pandemic, including 64.5% whose office visit numbers fell by half and 62.5% for whom most visits occurred virtually. Fewer experienced changes in their jobs; for example, only 14.9% had been furloughed. Three-quarters (76.6%) of these NHSC clinicians scored in at-risk levels for their well-being. Compared with primary care and behavioral health clinicians, dental clinicians much more often had been furloughed and had their practices close temporarily. CONCLUSIONS: The pandemic has disrupted the work, jobs, and mental health of NHSC clinicians in ways similar to its reported effects on outpatient clinicians generally. Because clinicians' mental health worsens after a pandemic, which leads to patient disengagement and job turnover, national programs and policies should help safety-net practices build cultures that support and give greater priority to clinicians' work, job, and mental health needs now and before the next pandemic.

The medicalization of sleeplessness: a public health concern.

Sleeplessness, a universal condition with diverse causes, may be increasingly diagnosed and treated (or medicalized) as insomnia. We examined the trend in sleeplessness complaints, diagnoses, and prescriptions of sedative hypnotics in physician office visits from 1993 to 2007. Consistent with the medicalization hypothesis, sleeplessness complaints and insomnia diagnoses increased over time and were far outpaced by prescriptions for sedative hypnotics. Insomnia may be a public health concern, but potential overtreatment with marginally effective, expensive medications with nontrivial side effects raises definite population health concerns.

Effect of sedentary behaviour and vigorous physical activity on segment-specific carotid wall thickness and its progression in a healthy population.

AIMS: This study investigated whether sedentary behaviour and different activity levels have an independent association with carotid intima-media thickness (IMT) and with the 3-year IMT progression in different carotid segments. METHODS AND RESULTS: The study population included 614 healthy men and women (mean age = 44 +/- 8 years) without carotid atherosclerosis and without increased coronary heart disease risk, who underwent B-mode carotid ultrasound and objective physical activity assessment by accelerometer (mean monitoring time = 5.7 +/- 1.5 days). Time spent in sedentary (57.6 +/- 9.1%), light (41.0 +/- 9.2%), moderate and vigorous activities was determined. Sedentary behaviour was expressed as the ratio of time spent in sedentary and light activity (sedentary/light ratio) as these two activities occupied the majority of waking time. In 495 subjects, the carotid ultrasound was repeated 3 years after the baseline examination. After adjustment for age and the established risk factors that were independent determinants of carotid wall thickness in our population, sedentary/light ratio was independently associated only with the common carotid artery (CCA) IMT. The 3-year increase in CCA IMT was significantly lower in subjects with periods of vigorous activity (7 +/- 40 microm) when compared with those with light activity only or with periods of moderate activity (22 +/- 51 and 19 +/- 46 microm, respectively, P < 0.05). CONCLUSION: The healthy, young-to-middle age population of this study spent more than half of their waking time in sedentary activities. The proportion of time spent in sedentary activities was directly associated with baseline CCA IMT, independently of age and established atherosclerotic risk factors. In the longitudinal analysis, period of vigorous activity influenced the 3-year IMT progression in CCA.

Holding up the oral health safety net: the role of National Health Service Corps alumni dentists in North Carolina.

BACKGROUND: Access to oral health care among low income populations is a growing problem. The National Health Service Corps (NHSC) might increase the supply of dentists motivated to provide services for this population. OBJECTIVE: To determine if North Carolina dentists who began a service obligation with the NHSC in 1990-1999 continued to provide care for underserved populations and if they differ from non-NHSC alumni primary care dentists who started practice in the state during that same period. METHODS: All 19 NHSC alumni and 50 comparison dentists were surveyed by mail. NHSC alumni also responded to selected items in a telephone follow-up interview. The two groups were compared using difference of means tests and multivariate contingency tables. RESULTS: National Health Service Corps alumni were more likely to be African-American (38%vs. 10%), work in safety net practices (84%vs. 23%), and see more publicly insured patients (60%vs. 19%) than comparison dentists. Yet their job satisfaction was comparable to non-NHSC alumni dentists. Analyses suggested that current practice in safety net settings is affected by dentists' race, altruistic motivations and previous NHSC participation. CONCLUSION AND POLICY IMPLICATION: Targeted recruitment of African-American dentists and others wanting to work in underserved communities could amplify the effectiveness of the financial incentive of NHSC loan repayment and induce dentists to remain in 'safety net' settings.

Serum sclerostin and glucose homeostasis: No association in healthy men. Cross-sectional and prospective data from the EGIR-RISC study.

INTRODUCTION: Sclerostin, an inhibitor of bone formation, has emerged as a potential negative regulator of glucose homeostasis. We aimed to investigate if serum sclerostin associates with insulin sensitivity, beta cell function, prediabetes or metabolic syndrome in healthy men. MATERIALS AND METHODS: Serum sclerostin was measured in basal and insulin-stimulated samples from 526 men without diabetes from the RISC cohort study. An OGTT was performed at baseline and after 3 years. An IVGTT and a hyperinsulinaemic-euglycaemic clamp were performed at baseline. Insulin sensitivity was estimated by the oral glucose sensitivity index (OGIS) and the M-value relative to insulin levels. Beta cell function was assessed by the acute and total insulin secretion (ISRtot) and by beta cell glucose sensitivity. RESULTS: Serum sclerostin levels correlated positively with age but were similar in individuals with (n = 69) and without (n = 457) prediabetes or the metabolic syndrome. Serum sclerostin was associated with measures of neither insulin sensitivity nor beta cell function at baseline in age-adjusted analyses including all participants. However, baseline serum sclerostin correlated inversely with OGIS at follow-up in men without prediabetes (B: -0.29 (-0.57, -0.01) p = 0.045), and inversely with beta cell glucose sensitivity in men with prediabetes (B: -13.3 (-26.3, -0.2) p = 0.046). Associations between serum sclerostin and 3-year changes in measures of glucose homeostasis were not observed. Acute hyperinsulinemia suppressed serum sclerostin (p = 0.02), and this reduction correlated with OGIS and ISRtot. CONCLUSIONS: Overall, serum sclerostin was not associated with prediabetes, insulin sensitivity or insulin secretion in healthy men. The inverse relationship between serum sclerostin and insulin sensitivity at follow-up was weak and likely not of clinical relevance. The ability of insulin to reduce sclerostin, possibly promoting bone formation, needs to be clarified.

Amplitude damping of Laguerre-Gaussian modes.

We present an amplitude damping channel for Laguerre-Gaussian modes. Our channel is tested experimentally for a Laguerre-Gaussian mode, having an azimuthal index l = 1, illustrating that it decays to a Gaussian mode in good agreement with the theoretical model for amplitude damping. Since we are able to characterize the action of such a channel on orbital angular momentum states, we propose using it to investigate the dynamics of entanglement.

It's about time: physicians' perceptions of time constraints in primary care medical practice in three national healthcare systems.

BACKGROUND: As physicians are pressured to deliver an increasing number of preventive services, follow guidelines, engage in evidence-based practice, and deliver patient-centered care in managerially driven organizations, they struggle with how much control they have over their time. METHODS: A secondary analysis was conducted with data from 3 parallel studies of clinical decision making in Germany, the United Kingdom, and the United States with 128 physicians per country. Physicians reported how much time they were allocated and how much time they needed for high-quality care for new patient appointments, routine consultations, and complete physicals. They also reported how much control they had over their time in the office and spending adequate time with patients. RESULTS: German, British, and American physicians were allocated (on average) 16/11/32 minutes for a new patient appointment, 6/10/18 minutes for a routine visit, and 12/20/36 minutes for a complete physical, but felt that they needed more time. Over half of German and American physicians felt that they always or usually had control over the hours they were required to be in their office or spending sufficient time with their patients while less than half of British physicians felt this way. CONCLUSION: German physicians had the least time allocated and needed for most types of appointment. American physicians had the most time allocated and needed for each type of appointment. However, British physicians felt they had the least control over time in their office and spending sufficient time with patients.

Brief communication: physician interest in volunteer service during retirement.

BACKGROUND: Baby boomers approaching retirement will include unprecedented numbers of physicians, many of whom want to remain productive. OBJECTIVE: To determine interest in health care-related volunteering during retirement among physicians trained to provide general medical care to adults. DESIGN: Cross-sectional mailed survey conducted May through July 2006. SETTING: North Carolina. PARTICIPANTS: 910 physicians, 55 years of age or older, whose primary specialty involved direct, nonsurgical care of adults. MEASUREMENTS: Current volunteerism and future interest in selected activities. RESULTS: Of the respondents, 89.8% were male and 87.4% were white; 57.4% worked full-time, 21.7% worked part-time, and 21.0% were retired. Of current retirees, 37.1% expressed interest in volunteering. Areas of greatest interest were medical teaching, working in free medical clinics, and international care. Strong incentives included staying mentally active (67.3%) or involved in medicine (61.2%) and contributing to society (60.5%). Substantial barriers included concerns about malpractice (61.5%) and paperwork or bureaucracy (46.0%). The majority of respondents (66.7%) felt that lack of payment would not influence volunteering. LIMITATIONS: The 59% overall response rate and exclusion of unlicensed retired physicians limit study generalizability. The data were provided by self-response and could not be independently validated. CONCLUSION: Retired physicians are a potential source of manpower that could contribute to provision of health care, particularly in medical teaching and clinical care of underserved persons.

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.

Satisfaction of the Primary Care, Mental Health, and Dental Health Clinicians of the National Health Service Corps Loan Repayment Program.

The National Health Service Corps (NHSC) aims to foster a positive service experience for its clinicians to promote long-term retention. We assess the satisfaction of primary care, dental, and mental health clinicians in the NHSC's Loan Repayment Program (LRP). Survey data are from 1,193 clinicians (72.4% response) who completed NHSC LRP contracts in 16 states from July 2015 through December 2016. Eighty-one percent reported overall satisfaction with their work and practice, without differences across disciplines. Nearly 95% were satisfied with the mission and patients of their practices. Fewer clinicians were satisfied with compensation (51%) and time demands of work (36%). Ninety-four percent reported the NHSC experience met or exceeded their expectations, and 94% recommend the NHSC LRP to others. In summary, the NHSC LRP experience is generally positive for clinicians of all disciplines. Clinicians' issues with their incomes and with the time demands of their work deserve attention from the NHSC.
