CLOSING THE GAP BETWEEN MEDICAL KNOWLEDGE AND PATIENT OUTCOMES THROUGH NEW TRAINING INFRASTRUCTURE.

The biomedical research infrastructure of our academic medical centers elucidates disease mechanisms and develops diagnostic tests and treatments with scientific rigor, but the mechanism for reliably moving these findings into clinical settings lacks careful design. Hence, there is a wide gap between medical discoveries and the health benefit realized by the U.S. population. Performance improvement (PI) is a discipline that focuses on intentional redesign of core processes in our health system to close these gaps. The application of PI science is more consequential to health outcomes as is traditional biomedical research. This article describes why application and recognition of PI science as a discipline is imperative and why we should require training with similar intensity in undergraduate medical education (UME) and graduate medical education (GME). It also proposes investment in infrastructure (developing faculty expertise) and rigorous fellowships, which are, perhaps, more likely to thrive in teaching hospitals with a strong clinical mission.

A cohort study of neuropsychological functioning in spouses of U.S. Gulf War veterans.

AIMS: Veterans of the 1991 Gulf War reported symptoms in their spouses that mirrored veterans' symptoms following their return from the war, including problems with attention and memory. Neuropsychological functioning in these spouses has not been examined with objective tests. This study sought to determine if these spouses exhibited deficits in neuropsychological functioning. MAIN METHODS: Spouses of a national cohort of 1991 Gulf War deployed (n = 470) and non-deployed veterans (n = 524) were examined with neuropsychological tests in 1999-2001. KEY FINDINGS: Neuropsychological tests were factor analyzed yielding five factors: verbal memory, visual memory, attention/working memory, visual organization, and motor speed. Spouses of deployed and nondeployed veterans did not differ on mean factor scores, percentage of impaired factors, or individual test scores. Spouse attention/working memory was related to their having diagnoses of PTSD or anxiety disorders, or self-reported symptoms of current anxiety. Spouse visual memory was related to a diagnosis of current depression. Spouse motor speed was related to their own status of having chronic multisymptom illness (CMI). SIGNIFICANCE: Spouses of Gulf War deployed and nondeployed veterans demonstrated similar neuropsychological functioning, although spouses with psychiatric diagnoses and symptoms, or CMI demonstrated neuropsychological impairments characteristic of those conditions, suggesting that monitoring spouses for these conditions and impairments may be warranted. This pattern of relative weaknesses mirrors some of the previously reported findings for Gulf War veterans, although the veterans displayed neuropsychological impairments beyond what was accounted for by these conditions.

Effectiveness of a novel, automated telephone intervention on time to hospitalisation in patients with COPD: A randomised controlled trial.

Introduction: Owing to its capacity to perform remote assessments, telemedicine is rising as a new force in chronic obstructive pulmonary disease (COPD) management. We conducted an eight month randomised-controlled-trial to study the effect of an automated telemedicine intervention on patients' time-to-hospitalisation. Methods: A total of 168 patients with a diagnosis of COPD in the past 24 months were enrolled to receive the intervention at a primary care clinic. The treatment group received daily phone messages from an automated system asking them to report if they were breathing better than, worse than, or the same as the day prior. Patients reported their breathing status by responding to the text message or call. If a patient reported breathing worse, an alert was sent directly to that patient's provider within the clinic. The control group received the same daily phone messages as the treatment group. However, no proactive breathing alerts were ever generated to the provider for these subjects. The primary outcome was the subjects' time-to-first-COPD-related hospitalisation following the start of messages. Results: The treatment group's time-to-hospitalisation was significantly different than the control group's with a hazard ratio of 2.36 (95% confidence interval 1.02­5.45, p = 0.0443). The number needed-to-treat ratio was 8.62. Subject engagement consistently ranged between 60% and 75%. The treatment group received both proactive monitoring and follow-up care from the providers. Discussion: Active monitoring with provider feedback enables the detection of exacerbation events early enough for subjects to avoid admissions. The use of non-smartphone interventions reduces barriers to care presented by more complicated and expensive technologies. This intervention represents a simple, innovative, and inexpensive tool for improved COPD management.

Mental health in spouses of U.S. Gulf War veterans.

Veterans' spouses are at risk for mental distress and substance use. We examined long term psychological functioning in spouses from a national cohort of 1991 Gulf War era veterans. From clinical interviews, spouses of deployed veterans (n = 488) did not have a greater prevalence of post-war mental disorders compared to spouses of non-deployed veterans (n = 536); however, in couples that were living together since the war, there was an increased risk of anxiety disorders or any one disorder. On questionnaires, the impact varied but was most consistently observed in more severe depression and greater functional impairment in spouses of deployed compared to non-deployed veterans. If a veteran developed post-war anxious/depressive disorders or any one mental disorder, the matched spouse was more likely to develop post-war anxious/depressive disorders or any one mental disorder, respectively. Veteran combat exposure did not similarly increase the risk of spouse post-war mental disorders. Greater spouse self-reported symptomatology was observed in spouses of veterans with anxious/depressive disorders even when controlling for deployment. In summary, the war conferred greater risk for spouse mental disorders and distress for spouses of veterans with mental health disorders, with some increased risk for spouses of deployed veterans, especially in couples together since the war.

Birth Defects Among 788 Children Born to Gulf War Veterans Based on Physical Examination.

OBJECTIVE: The aim of the study was to examine the prevalence of birth defects among children born to Gulf War veterans. METHODS: Seven hundred eighty-eight singleton children born after the war to 522 veterans (262 Gulf War-deployed, DV; 260 non-deployed, NDV) underwent physical examinations focusing on major and minor birth defects and other findings. RESULTS: We found no differences between children of DV and NDV in the prevalence of major birth defects or other findings. However, children of DV women were more likely to have minor birth defects compared with children of NDV women (DV 22% NDV 4.8%, odds ratio: 5.47, confidence interval: 2.06, 14.55), mainly due to increased incidence of minor eye and musculoskeletal birth defects. CONCLUSIONS: Our data show that deployment of women to the Persian Gulf arena was associated with increased risk of minor birth defects in their offspring.

Medical Correlates of Chronic Multisymptom Illness in Gulf War Veterans.

BACKGROUND: Chronic multisymptom illness (CMI) is more prevalent among deployed than nondeployed veterans from the first Gulf War. Objective physiologic markers of CMI are lacking. The purpose of this study is to determine whether measurable abnormalities in the autonomic nervous system or hypothalamic-pituitary adrenal axis would distinguish CMI cases (CMI+) from controls (CMI-) among deployed veterans of the 1990-1991 Gulf War. METHODS: This is a cross-sectional case-control cohort study that examined deployed veterans who participated in the Phase III study: National Health Survey of Gulf War Veterans and Their Families. Autonomic nervous system and hypothalamic-pituitary adrenal axis function-related measures included: 24-hour heart-rate variability, urinary catecholamines and cortisol, hypertension, insulin sensitivity, dyslipidemia, body fat, bone mineral density, and ultrasensitive C-reactive protein. RESULTS: Veterans of the first Gulf War with CMI (n = 73) and without the condition (n = 111) were studied. Sociodemographic characteristics were similar. Veterans with CMI reported poorer mental and physical functioning, greater use of prescription medications, and more nonroutine clinic visits. These veterans were also more likely to have fibromyalgia syndrome, irritable bowel syndrome, metabolic syndrome, and among males, a larger waist-to-hip ratio. Lower values for a nonlinear heart-rate-variability parameter-the short-term fractal scaling exponent (DFA1), reflecting an increased randomness of beat-to-beat changes in heart rate-were observed in veterans with CMI than those veterans without it (1.28±0.16vs 1.35±0.15; p=0.005). Hypothalamic-pituitary-adrenal axis function measures were similar between the two groups. CONCLUSION: In this cohort of deployed veterans from the first Gulf War, we identified abnormal heart-rate variability in veterans with CMI compared to veterans without the condition, which suggests abnormal functioning of the autonomic nervous system and possible long-term cardiovascular effects.

Training the physician-scientist: views from program directors and aspiring young investigators.

There is growing concern that the physician-scientist is endangered due to a leaky training pipeline and prolonged time to scientific independence (1). The NIH Physician-Scientist Workforce Working Group has concluded that as many as 1,000 individuals will need to enter the pipeline each year to sustain the workforce (2). Moreover, surveys of postgraduate training programs document considerable variability in disposition and infrastructure (3). Programs can be broadly grouped into two classes: physician-scientist training programs (PSTPs) that span residency and fellowship training, and research-in-residency programs (RiRs), which are limited to residency but trainees are able to match into PSTPs upon transitioning to fellowship (Figure 1). Funding sources for RiRs and PSTPs are varied and include NIH KL2 and T32 awards, charitable foundations, philanthropy, and institutional support. Furthermore, standards for research training and tools for evaluating programmatic success are lacking. Here, we share consensus generated from iterative workshops hosted by the Alliance of Academic Internal Medicine (AAIM) and the student-led American Physician Scientists Association (APSA).

U.S. Physician-Scientist Workforce in the 21st Century: Recommendations to Attract and Sustain the Pipeline.

The U.S. physician-scientist (PS) workforce is invaluable to the nation's biomedical research effort. It is through biomedical research that certain diseases have been eliminated, cures for others have been discovered, and medical procedures and therapies that save lives have been developed. Yet, the U.S. PS workforce has both declined and aged over the last several years. The resulting decreased inflow and outflow to the PS pipeline renders the system vulnerable to collapsing suddenly as the senior workforce retires. In November 2015, the Alliance for Academic Internal Medicine hosted a consensus conference on the PS workforce to address issues impacting academic medical schools, with input from early-career PSs based on their individual experiences and concerns. One of the goals of the conference was to identify current impediments in attracting and supporting PSs and to develop a new set of recommendations for sustaining the PS workforce in 2016 and beyond. This Perspective reports on the opportunities and factors identified at the conference and presents five recommendations designed to increase entry into the PS pipeline and nine recommendations designed to decrease attrition from the PS workflow.

Increased Risk of Chronic Multisymptom Illness in Spouses of Gulf War Era Veterans.

OBJECTIVE: In 1995, the Centers for Disease Control and Prevention defined chronic multisymptom illness (CMI), a symptom complex in deployed veterans (DVs) of the 1991 Gulf War 1. The specific aim of this work is to determine the prevalence of CMI in spouses of DV and nondeployed veterans (NDVs) and whether veteran CMI is associated with spouse CMI, and to describe the physical and psychological profile of spouses with CMI. MATERIALS AND METHODS: To determine whether veteran CMI was associated with CMI in their spouses, we used retrospective data from the "National Health Survey of Gulf War Veterans and Their Families." Cross-sectional data were collected from spouses of veterans enrolled in the study, including those of 482 DVs and 532 NDVs who participated in an in-person examination between 1999 and 2001. In addition to a physical examination, this study evaluated health-related quality of life (Medical Outcomes Study Short-Form 36, SF-36), psychological symptoms, and post-traumatic stress disorder (PTSD) status, and measured a variety of common laboratory tests. Statistical analyses included Fisher's Exact Test (or Mantel-Haenszel χ2 test for linear trend) as well as odds ratios (ODs) and 95% confidence intervals (CIs) for categorical data. For continuous outcomes, two-sample t-tests were used to compare mean responses among spouses of DV and NDV with and without CMI, and between spouses of DV and NDV with CMI only. Logistic or linear regression models were developed for multiple-covariate analysis to assess if any of the associations we found in the unadjusted analyses would change. The project was approved by the Hines Cooperative Studies Program Human Rights Committee, the Institutional Review Boards at each participating site, and the Brockton VAMC. RESULTS: The prevalence of CMI in spouses was 19.5% (DV) and 17.3% (NDV) (odds ratio [OR]: 1.16; 95% confidence interval [CI]: 0.84, 1.59). Spouses were more likely to have CMI if their veteran partner had CMI (OR: 1.49; 95% CI: 1.01, 2.19) or PTSD (OR: 1.84; 95% CI: 1.01, 3.37). Deployment was not a predictor of CMI. Spouses with CMI reported poorer SF-36 physical and mental component scores; worse symptoms of depression, anxiety, and post-traumatic stress; and a higher percentage had probable PTSD, more nonroutine clinic visits, more hospitalization, more prescription medications, and more psychotropic medication use compared with spouses without CMI regardless of the deployment status of their veteran spouses. CONCLUSION: Spouses of veterans with CMI report worse physical and mental functioning than spouses of veterans without CMI, regardless of the veteran's deployment status. Strengths of the study include that all participants were selected independently of veteran medical or psychiatric illness, and all underwent comprehensive health assessments. Weaknesses of the study include that data were not collected blindly, and that we made minor modifications of the Centers for Disease Control and Prevention diagnosis, such as defining fatigue and musculoskeletal pain more restrictively. The impact of veteran CMI on their spouse's health is likely to be significant in terms of medical cost and morbidity. Efforts to reduce the impact of CMI in the future should include identifying soldiers who are more vulnerable, such as those with prior GWI or PTSD.

Use of a 90-Minute Admission Window and Front-Fill System to Reduce Work Compression on a General Medicine Inpatient Teaching Service.

BACKGROUND: Duty hour limits have shortened intern shifts without concurrent reductions in workload, creating work compression. Multiple admissions during shortened shifts can result in poor training experience and patient care. OBJECTIVE: To relieve work compression, improve resident satisfaction, and improve duty hour compliance in an academic internal medicine program. METHODS: In 2014, interns on general ward services were allotted 90 minutes per admission from 3 pm to 7 pm, when the rate of admissions was high. Additional admissions arriving during the protected period were directed to hospitalists. Resident teams received 2 patients admitted by the night float team to start the call day (front-fill). RESULTS: Of the 51 residents surveyed before and after the implementation of the intervention, 39 (77%) completed both surveys. Respondents reporting an unmanageable workload fell from 14 to 1 (P < .001), and the number of residents reporting that they felt unable to admit patients in a timely manner decreased from 14 to 2 (P < .001). Reports of adequate time with patients increased from 16 to 36 (P < .001), and residents indicating that they had time to learn from patients increased from 19 to 35 (P < .001). Reports of leaving on time after call days rose from 12 to 33 (P < .01), and overall satisfaction increased from 26 to 35 (P = .002). Results were similar when residents were resurveyed 6 months after the intervention. CONCLUSIONS: Call day modifications improved resident perceptions of their workload and time for resident learning and patient care.

Improving Glycemic Control With a Standardized Text-Message and Phone-Based Intervention: A Community Implementation.

BACKGROUND: Type II diabetes mellitus (T2DM) presents a major disease burden in the United States. Outpatient glycemic control among patients with T2DM remains difficult. Telemedicine shows great potential as an adjunct therapy to aid in glycemic control in real-world settings. OBJECTIVE: We aimed to explore the effectiveness of EpxDiabetes, a novel digital health intervention, in improving hemoglobin A1c (HbA1c) and fasting blood glucose (FBG) among patients with uncontrolled diabetes. METHODS: We recruited 396 patients from a community clinic in St. Louis, Missouri, from a database of patients diagnosed with T2DM and with a most recent HbA1c >7% as part of a quality improvement project. An automated call or text-messaging system was used to monitor patient-reported FBG. If determined to be elevated, care managers were notified by email, text, or electronic medical record alert. Participants self-reported their FBG data by replying to EpxDiabetes automated phone calls or text messages. Data were subsequently analyzed, triaged, and shared with providers to enable appropriate follow-up and care plan adjustments. Absolute HbA1c reduction, patient engagement, and absolute patient-reported FBG reduction were examined at approximately 6 months post implementation. RESULTS: EpxDiabetes had an average 95.6% patient response rate to messages at least once per month and an average 71.1% response rate to messages at least once per week. Subsequent HbA1c drop with EpxDiabetes use over 4 months was -1.15% (95% CI -1.58 to -0.71) for patients with HbA1c >8% at baseline compared to the change in HbA1c over 4 months prior to the implementation of EpxDiabetes of only -0.005 points (95% CI -0.28 to 0.27), P=.0018. CONCLUSIONS: EpxDiabetes may help reduce HbA1c in patients with high HbA1c baselines (>8%). The intervention demonstrates high patient engagement sustainable for at least 6 months.

Assessing the Utility of a Novel SMS- and Phone-Based System for Blood Pressure Control in Hypertensive Patients: Feasibility Study.

BACKGROUND: Although hypertension (HTN) is a major modifiable risk factor for arterial damage, blood pressure (BP) remains poorly controlled in the hypertensive population. Telemedicine is a promising adjunct intervention that may complement traditional therapies and improve adherence rates; however, current approaches have multiple barriers to entry, including the use of relatively expensive Bluetooth devices or the dependence on smart phone utilization, which tend to exclude low-income and more elderly populations. OBJECTIVE: The aim of this study was to design and implement a new phone call- and short message service text messaging-based intervention, Epharmix's EpxHypertension, in a quality improvement project that demonstrates the feasibility of this system for BP control in a family medicine setting. METHODS: We recruited 174 patients from a community clinic in St Louis from a database of patients diagnosed with HTN. An automated call or text messaging system was used to monitor patient-reported BPs. If determined to be elevated, physicians were notified by an email, text, or electronic medical record alert. Mean systolic BPs (SBPs) and diastolic BPs (DBPs) were compared at the beginning and end of 12 weeks. RESULTS: After 12 weeks on the system, patients with a baseline SBP of 140 mm Hg or higher reduced SBP by 10.8 mm Hg (95% CI -14.5 to -7.2, P<.001) and DBP by 6.6 mm Hg (95% CI -9.9 to -3.4, P=.002), but no significant changes were observed in overall BPs and BPs in the group with baseline SBP less than 140 mm Hg. CONCLUSIONS: EpxHypertension provides a viable means to control HTN in patients with high baseline BPs despite previous therapy. This community implementation study demonstrates the feasibility of implementing EpxHypertension across a primary care setting without the need for smartphones or Bluetooth-linked BP cuffs. Future studies should evaluate its effectiveness in a randomized control trial compared with standard of care.

A Novel Patient Engagement Platform Using Accessible Text Messages and Calls (Epharmix): Feasibility Study.

BACKGROUND: Patient noncompliance with therapy, treatments, and appointments represents a significant barrier to improving health care delivery and reducing the cost of care. One method to improve therapeutic adherence is to improve feedback loops in getting clinically acute events and issues to the relevant clinical providers as necessary (ranging from detecting hypoglycemic events for patients with diabetes to notifying the provider when patients are out of medications). Patients often don't know which information should prompt a call to their physician and proactive checks by the clinics themselves can be very resource intensive. We hypothesized that a two-way SMS system combined with a platform web service for providers would enable both high patient engagement but also the ability to detect relevant clinical alerts. OBJECTIVE: The objectives of this study are to develop a feasible two-way automated SMS/phone call + web service platform for patient-provider communication, and then study the feasibility and acceptability of the Epharmix platform. First, we report utilization rates over the course of the first 18 months of operation including total identified clinically significant events, and second, review results of patient user-satisfaction surveys for interventions for patients with diabetes, COPD, congestive heart failure, hypertension, surgical site infections, and breastfeeding difficulties. METHODS: To test this question, we developed a web service + SMS/phone infrastructure ("Epharmix"). Utilization results were measured based on the total number of text messages or calls sent and received, with percentage engagement defined as a patient responding to a text message at least once in a given week, including the number of clinically significant alerts generated. User satisfaction surveys were sent once per month over the 18 months to measure satisfaction with the system, frequency and degree of communication. Descriptive statistics were used to describe the above information. RESULTS: In total, 28,386 text messages and 24,017 calls were sent to 929 patients over 9 months. Patients responded to 80% to 90% of messages allowing the system to detect 1164 clinically significant events. Patients reported increased satisfaction and communication with their provider. Epharmix increased the number of patient-provider interactions to over 10 on average in any given month for patients with diabetes, COPD, congestive heart failure, hypertension, surgical site infections, and breastfeeding difficulties. CONCLUSIONS: Engaging high-risk patients remains a difficult process that may be improved through novel, digital health interventions. The Epharmix platform enables increased patient engagement with very low risk to improve clinical outcomes. We demonstrated that engagement among high-risk populations is possible when health care comes conveniently to where they are.

Estimates of Mental Health Problems in a Vulnerable Population within a Primary Care Setting.

We examined the prevalence of mental disorders in a primary care setting affiliated with a large academic medical center. We also examined whether there were racial differences in mental health disorders. Patients were seeking medical care in an outpatient medical clinic; mental health data were available for them via medical records (n=767). Overall, 45% of patients had a diagnosed mental health problem; the most commonly reported form of mental disorder was depression. African Americans (OR= 1.88; CI: 1.21-2.91) were more likely than Whites to have a diagnosed mental health problem. These results suggest a strong mental health treatment need among patients seeking primary care in urban settings. The evidence garnered from this study underscores the need to detect and treat mental health problems systematically within outpatient primary care clinics that serve similarly vulnerable populations.

Curbing the Urge to Image.

Health care costs in the US have grown rapidly over the past several decades. As a result, there has been increasing interest in strategies to contain health care costs, without sacrificing the quality of medical care. While many factors contribute to rising costs, one major contributor to health care expenditure is diagnostic imaging. In this article, we address the growth of diagnostic imaging, the financial and clinical adverse effects of over-utilization, and discuss a variety of strategies to encourage appropriate use of diagnostic testing.

Relationships Between Health Literacy and Genomics-Related Knowledge, Self-Efficacy, Perceived Importance, and Communication in a Medically Underserved Population.

The increasing importance of genomic information in clinical care heightens the need to examine how individuals understand, value, and communicate about this information. Based on a conceptual framework of genomics-related health literacy, we examined whether health literacy was related to knowledge, self-efficacy, and perceived importance of genetics and family health history (FHH) and communication about FHH in a medically underserved population. The analytic sample was composed of 624 patients at a primary care clinic in a large urban hospital. About half of the participants (47%) had limited health literacy; 55% had no education beyond high school, and 58% were Black. In multivariable models, limited health literacy was associated with lower genetic knowledge (ß = -0.55, SE = 0.10, p < .0001), lower awareness of FHH (odds ratio [OR] = 0.50, 95% confidence interval [CI; 0.28, 0.90], p = .020), and greater perceived importance of genetic information (OR = 1.95, 95% CI [1.27, 3.00], p = .0022) but lower perceived importance of FHH information (OR = 0.47, 95% CI [0.26, 0.86], p = .013) and more frequent communication with a doctor about FHH (OR = 2.02, 95% CI [1.27, 3.23], p = .0032). The findings highlight the importance of considering domains of genomics-related health literacy (e.g., knowledge, oral literacy) in developing educational strategies for genomic information. Health literacy research is essential to avoid increasing disparities in information and health outcomes as genomic information reaches more patients.

Effect of Health Literacy on Decision-Making Preferences among Medically Underserved Patients.

INTRODUCTION: Participation in the decision-making process and health literacy may both affect health outcomes; data on how these factors are related among diverse groups are limited. This study examined the relationship between health literacy and decision-making preferences in a medically underserved population. METHODS: We analyzed a sample of 576 primary care patients. Multivariable logistic regression was used to examine the independent association of health literacy (measured by the Rapid Estimate of Adult Literacy in Medicine-Revised) and patients' decision-making preferences (physician directed or patient involved), controlling for age, race/ethnicity, and gender. We tested whether having a regular doctor modified this association. RESULTS: Adequate health literacy (odds ratio [OR] = 1.7;P= 0.009) was significantly associated with preferring patient-involved decision making, controlling for age, race/ethnicity, and gender. Having a regular doctor did not modify this relationship. Males were significantly less likely to prefer patient-involved decision making (OR = 0.65;P= 0.024). DISCUSSION: Findings suggest health literacy affects decision-making preferences in medically underserved patients. More research is needed on how factors, such as patient knowledge or confidence, may influence decision-making preferences, particularly for those with limited health literacy.
