Telehealth Behavioral Intervention for Chronic Disease Self-Management in Adults With Physical Disabilities (My Health, My Life, My Way): Protocol for Intervention Fidelity and Dashboard Design for a Randomized Controlled Trial.

BACKGROUND: Individuals with physical disabilities experience higher rates of chronic health conditions than individuals without physical disabilities. Self-management programs that use health coaching are effective at eliciting health behavior change in health outcomes such as goal setting, adherence, and health care use. Additionally, web-based resources such as telehealth-based technologies, including SMSS text messaging, web-based applications, and educational multimedia content, can complement health coaching to improve health-related behaviors and the use of health services. The complexity of studies using these resources requires a fidelity protocol to ensure that health behavior studies are administered properly. OBJECTIVE: The My Health, My Life, My Way fidelity protocol provides methods, strategies, and procedures of a multifaceted telehealth program for individuals with permanent physical disabilities and chronic health conditions. This health behavior study is a randomized controlled trial with four study arms: (1) scheduled coaching calls with gamified rewards, (2) no scheduled coaching calls with gamified rewards, (3) scheduled coaching calls with fixed rewards, and (4) no scheduled coaching calls with fixed rewards. To guide the fidelity protocol developed, we used the National Institutes of Health Behavior Change Consortium framework (NIH BCC). METHODS: The fidelity intervention protocol was developed by using the 5 primary domains provided by the NIH BCC: study design, provider training, treatment delivery, treatment receipt, and enactment of treatment skills. Following the NIH BCC guidelines and implementing social cognitive theory, this study is designed to ensure that all study arms receive equal treatment across conditions and groups. Health coaches and providers will be trained to deliver consistent health coaching, and thus participants will receive appropriate attention. Educational content will be developed to account for health literacy and comprehension of the material. Multiple fidelity intervention steps such as coaching call logs, regular content review, and participant progress monitoring will translate to participants using the skills learned in their daily lives. Different monitoring steps will be implemented to minimize differences among the 4 treatment groups. RESULTS: My Health, My Life, My Way has been approved by the institutional review board and will begin enrollment in January 2024 and end in December 2024, with results reported in early 2025. CONCLUSIONS: Intervention fidelity protocols are necessary to ensure that health behavior change studies can be implemented in larger real-world settings. The My Health, My Life, My Way fidelity protocol has used the guidelines by the NIH BCC to administer a telehealth intervention combined with health coaching for individuals with physical disabilities and chronic health conditions. This fidelity protocol can be used as a complementary resource for other researchers who conduct similar research using telehealth technologies and health coaching in real-world settings.

Stroke Severity, Caregiver Feedback, and Cognition in the REGARDS-CARES Study.

Objective: Cognitive impairment after stroke is common, present up to 60% of survivors. Stroke severity, indicated by both volume and location, is the most consequential predictor of cognitive impairment, with severe strokes predicting higher chances of cognitive impairment. The current investigation examines the associations of two stroke severity ratings and a caregiver-report of post-stroke functioning with longitudinal cognitive outcomes. Methods: The analysis was conducted on 157 caregivers and stroke survivor dyads who participated in the Caring for Adults Recovering from the Effects of Stroke (CARES) project, an ancillary study of the REasons for Geographic and Racial Differences in Stroke (REGARDS) national cohort study. Glasgow Outcome Scale (GOS) and modified Rankin Scale (mRS) collected at hospitalization discharge were included as two primary predictors of cognitive impairment. The number of caregiver-reported problems and impairments at nine months following stroke were included as a third predictor. Cognition was assessed using a biennial telephone battery, incorporating multiple cognitive assessments to assess learning, memory, and executive functioning. Longitudinal cognitive scores were analyzed up to five years post-stroke, controlling for baseline (pre-stroke) cognitive scores and demographic variables of each stroke survivor collected at CARES baseline. Results: Separate mixed models showed significant main effects of GOS (b=0.3280, p=0.0009), mRS (b=-0.2119, p=0.0002), and caregiver-reported impairments (b=-0.0671, p<0.0001) on longitudinal cognitive scores. In a combined model including all three predictors, only caregiver-reported problems significantly predicted cognitive outcomes (b=-0.0480, p<0.0001). Impact: These findings underscore the importance of incorporating caregivers feedback in understanding cognitive consequences of stroke.

Stakeholders' Perspectives, Needs, and Barriers to Self-Management for People With Physical Disabilities Experiencing Chronic Conditions: Focus Group Study.

BACKGROUND: While self-management programs have had significant improvements for individuals with chronic conditions, less is known about the impact of self-management programs for individuals with physical disabilities who experience chronic conditions, as no holistic self-management programs exist for this population. Similarly, there is limited knowledge of how other stakeholders, such as caregivers, health experts, and researchers, view self-management programs in the context of disability, chronic health conditions, and assistive technologies. OBJECTIVE: This study aimed to obtain insight into how stakeholders perceive self-management relating to physical disability, chronic conditions, and assistive technologies. METHODS: Nine focus groups were conducted by 2 trained facilitators using semistructured interview guides. Each guide contained questions relating to stakeholders' experiences, challenges with self-management programs, and perceptions of assistive technologies. Focus groups were audio recorded and transcribed. Thematic analysis was conducted on the focus group data. RESULTS: A total of 47 individuals participated in the focus groups. By using a constructivist grounded approach and inductive data collection, three main themes emerged from the focus groups: (1) perspectives, (2) needs, and (3) barriers of stakeholders. Stakeholders emphasized the importance of physical activity, mental health, symptom management, medication management, participant centeredness, and chronic disease and disability education. Participants viewed technology as a beneficial aide to their daily self-management and expressed their desire to have peer-to-peer support in web-based self-management programs. Additional views of technology included the ability to access individualized, educational content and connect with other individuals who experience similar health conditions or struggle with caregiving duties. CONCLUSIONS: The findings suggest that the development of any web-based self-management program should include mental health education and resources in addition to physical activity content and symptom management and be cost-effective. Beyond the inclusion of educational resources, stakeholders desired customization or patient centeredness in the program to meet the overall needs of individuals with physical disabilities and caregivers. The development of web-based self-management programs should be holistic in meeting the needs of all stakeholders.

My Health, My Life, My Way-An Inclusive Web-Based Self-management Program for People With Disabilities Living With Chronic Conditions: Protocol for a Multiphase Optimization Strategy Study.

BACKGROUND: Individuals with disabilities living with chronic health conditions require self-management programs that are accessible, sustainable, inclusive, and adaptable. Health coaching is an effective approach to promoting behavior change in self-management. Health coaching combined with telehealth technology has the potential to improve the overall quality of, and access to, health services. OBJECTIVE: This protocol outlines the study design for implementing the My Health, My Life, My Way intervention. The study will assess the feasibility, acceptability, and preliminary efficacy of the intervention for people with disabilities and optimize it. METHODS: The My Health, My Life, My Way study is a 4-arm randomized controlled trial evaluating the delivery of a 6-month intervention involving telecoaching, inclusive educational content, and technology access for 200 individuals with chronic conditions and physical disabilities. This study uses the engineering-inspired multiphase optimization strategy (MOST) framework to evaluate intervention components and assess whether a combination or lack of individual elements influences behavior. Participants will be randomized to 1 of 4 study arms: scheduled coaching calls and gamified rewards, no scheduled coaching calls and gamified rewards, scheduled coaching calls and flat rewards, and no scheduled coaching calls and flat rewards. RESULTS: The My Health, My Life, My Way study was approved by the institutional review board of the University of Alabama at Birmingham, and recruitment and enrollment will begin in May 2023. Data analysis is expected to be completed within 6 months of ending data collection. This clinical trial protocol was developed based on the SPIRIT (Standard Protocol Items: Recommendations for Interventional Trials) 2013 statement. CONCLUSIONS: The My Health, My Life, My Way study will help to optimize and improve our understanding of the feasibility and efficacy of a web-based self-management program for people with physical disabilities and chronic conditions. More specifically, My Health, My Life, My Way will determine which combination of interventions (coaching calls and gamification) will result in increased participation in self-management programming. The My Health, My Life, My Way intervention has the potential to become a scalable and novel method to successfully manage chronic conditions in people with disabilities.

Synthesis and Characterization of Ligand-Stabilized Silver Nanoparticles and Comparative Antibacterial Activity against E. coli.

Silver is a well-established antimicrobial agent. Conjugation of organic ligands with silver nanoparticles has been shown to create antimicrobial nanoparticles with improved pharmacodynamic properties and reduced toxicity. Twelve novel organic ligand functionalized silver nanoparticles (AgNPs) were prepared via a light-controlled reaction with derivatives of benzothiazole, benzoxazine, quinazolinone, 2-butyne-1,4-diol, 3-butyne-1-ol, and heptane-1,7-dioic. UV-vis, Fourier-transform infrared (FTIR) spectroscopy, and energy-dispersive X-ray (EDAX) analysis were used to confirm the successful formation of ligand-functionalized nanoparticles. Dynamic light scattering (DLS) revealed mean nanoparticle diameters between 25 and 278 nm. Spherical and nanotube-like morphologies were observed using transmission electron microscopy (TEM) and scanning electron microscopy (SEM). Seven of the twelve nanoparticles exhibited strong antimicrobial activity and five of the twelve demonstrated significant antibacterial capabilities against E. coli in a zone-of-inhibition assay. The synthesis of functionalized silver nanoparticles such as the twelve presented is critical for the further development of silver-nanoconjugated antibacterial agents.

Patients treated for acute headache with intranasal droperidol spend less time in the emergency department: A retrospective observational study.

OBJECTIVE: Headache is a common presenting complaint to the ED. Using time from the first provider to discharge as a surrogate for effectiveness, we aimed to determine if intranasal (IN) droperidol is as beneficial as usual treatment for acute headache in the ED. METHODS: There were 1213 consecutive presentations of adults with acute headache over a 42-month period. Electronic records for each event were interrogated, 406 events met pre-determined exclusion criteria. Of the remaining 805 eligible patient events, 139 received IN droperidol, whereas 666 were given usual therapy. RESULTS: There was a 20 min reduction of mean and median ED length of stay (LOS) for the group that got treated with IN droperidol. CONCLUSIONS: IN droperidol reduced LOS in the ED. There are potential cost savings of this effective treatment via this novel route. A prospective multi-centre study of the use of IN droperidol for the treatment of acute headache in the ED is recommended.

Stakeholder Perspectives on an Inpatient Hypoglycemia Informatics Alert: Mixed Methods Study.

BACKGROUND: Iatrogenic hypoglycemia is a common occurrence among hospitalized patients and is associated with poor clinical outcomes and increased mortality. Clinical decision support systems can be used to reduce the incidence of this potentially avoidable adverse event. OBJECTIVE: This study aims to determine the desired features and functionality of a real-time informatics alert to prevent iatrogenic hypoglycemia in a hospital setting. METHODS: Using the Agency for Healthcare Research and Quality Five Rights of Effective Clinical Decision Support Framework, we conducted a mixed methods study using an electronic survey and focus group sessions of hospital-based providers. The goal was to elicit stakeholder input to inform the future development of a real-time informatics alert to target iatrogenic hypoglycemia. In addition to perceptions about the importance of the problem and existing barriers, we sought input regarding the content, format, channel, timing, and recipient for the alert (ie, the Five Rights). Thematic analysis of focus group sessions was conducted using deductive and inductive approaches. RESULTS: A 21-item electronic survey was completed by 102 inpatient-based providers, followed by 2 focus group sessions (6 providers per session). Respondents universally agreed or strongly agreed that inpatient iatrogenic hypoglycemia is an important problem that can be addressed with an informatics alert. Stakeholders expressed a preference for an alert that is nonintrusive, accurate, communicated in near real time to the ordering provider, and provides actionable treatment recommendations. Several electronic medical record tools, including alert indicators in the patient header, glucose management report, and laboratory results section, were deemed acceptable formats for consideration. Concerns regarding alert fatigue were prevalent among both survey respondents and focus group participants. CONCLUSIONS: The design preferences identified in this study will provide the framework needed for an informatics team to develop a prototype alert for pilot testing and evaluation. This alert will help meet the needs of hospital-based clinicians caring for patients with diabetes who are at a high risk of treatment-related hypoglycemia.

Hippocampal volume varies with acute posttraumatic stress symptoms following medical trauma.

The hippocampus and amygdala play an important role in the pathophysiology of posttraumatic stress disorder (PTSD). In fact, chronic PTSD has been consistently linked to reductions in hippocampal and amygdala volume. However, the acute impact posttraumatic stress has on the volume of these brain regions has received limited attention. Determining the acute impact posttraumatic stress has on brain volume may improve our understanding of the development of PTSD. Therefore, the present study recruited participants acutely (i.e., ∼1-month posttrauma) following trauma exposure and examined the relationship between brain volume (assessed at ∼1-month posttrauma) and posttraumatic stress symptoms (assessed at ∼1 and >3-months posttrauma) to determine whether brain volume was associated with acute posttraumatic stress symptom expression. Twenty-one trauma-exposed (TE) patients and 19 nontrauma-exposed (NTE) controls were recruited for the present study. Brain volume was assessed by structural magnetic resonance imaging completed during the ∼1-month assessment. Left hippocampal volumes were smaller in TE than NTE participants. Among TE participants, bilateral hippocampal volumes decreased as the number of days posttrauma increased. Further, bilateral hippocampal volumes varied negatively with the severity of posttraumatic stress symptoms at ∼1-month posttrauma. The present findings suggest that there is a progressive decrease in hippocampal volume acutely (e.g., within approximately 1 month) following trauma exposure, and demonstrates that acutely assessed hippocampal volumes vary with posttraumatic stress symptom expression.

Juntos: A Model for Language Congruent Care to Better Serve Spanish-Speaking Patients with COVID-19.

Coronavirus disease 2019 (COVID-19) exacerbated pre-existing health disparities and disproportionately affected the Latino community. Clinicians identified communication barriers as a major challenge in care for COVID-19 Latino patients with limited English proficiency (LEP). To address these challenges, Juntos (Together) consult service was established to promote language-congruent care with cultural sensitivity, identify barriers to safe discharge, and facilitate referral to appropriate resources. Spanish speaking volunteer health care providers worked synergistically with medical teams caring for LEP Latino patients. Volunteers were trained on consultant responsibilities and discharge planning resources. The program was evaluated by a satisfaction survey distributed to providers who requested a Juntos consult and Juntos volunteers. Between May 5 and July 30, 2020, 19 individuals volunteered time to the Juntos consult service, 12 (63%) Latinos, 14 (74%) physicians, and 5 (26%) staff. The service supported 127 patients, 76 (60%) males, mean age 42 (±16), 83 (65%) uninsured, and 91 (72%) without primary care. The most common referral sources were medical units (52, 41%) and intensive care units (47, 37%). The most common services offered were family engagement (55, 43%), goals of care (35, 28%), and mental status assessment (26, 20%). The majority of providers who consulted Juntos were very satisfied (48/59, 81%) with the care delivered. The Juntos service offered critical support tailored to the patients' and primary teams' needs. The experience reinforced the need for cultural-based communication to provide optimal care to LEP patients. The Juntos consult service could be a model for providing language-congruent care even beyond COVID-19, but to do so will require institutional investment and rigorous outcomes evaluation.

White matter microstructure varies with post-traumatic stress severity following medical trauma.

The prefrontal cortex, amygdala, hippocampus, and hypothalamus are important components of the neural network that mediates the healthy learning, expression, and regulation of emotion. These brain regions are connected by white matter pathways that include the cingulum bundle, uncinate fasciculus, and fornix/stria terminalis. Individuals with trauma and stress-related disorders show dysfunction of the cognitive-affective processes supported by the brain regions these white matter tracts connect. Therefore, variability in the microstructure of these white matter pathways may play an important role in the cognitive-affective dysfunction related to post-traumatic stress disorder. Thus, the current study used diffusion weighted imaging to assess the white matter microstructure of the cingulum bundle, uncinate fasciculus, and fornix/stria terminalis acutely (< 1 month) following trauma. Further, we assessed both acute (i.e., < 1 month) and subacute (i.e., 3 months post-trauma) post-traumatic stress symptom severity. White matter microstructure (assessed < 1 month post-trauma) of the uncinate fasciculus and fornix/stria terminalis varied with acute post-traumatic stress severity (assessed < 1 month post-trauma). Further, white matter microstructure (assessed < 1 month post-trauma) of the cingulum bundle and fornix/stria terminalis varied with subacute post-traumatic stress severity (assessed 3 months post-trauma). The current results suggest white matter architecture of the prefrontal cortex - amygdala network plays an important role in the development of trauma and stress-related disorders.

The Effect of Eliminating Intermediate Severity Drug-Drug Interaction Alerts on Overall Medication Alert Burden and Acceptance Rate.

OBJECTIVE: This study aimed to determine the effects of reducing the number of drug-drug interaction (DDI) alerts in an order entry system. METHODS: Retrospective pre-post analysis at an urban medical center of the rates of medication alerts and alert acceptance during a 5-month period before and 5-month period after the threshold for firing DDI alerts was changed from "intermediate" to "severe." To ensure that we could determine varying response to each alert type, we took an in-depth look at orders generating single alerts. RESULTS: Before the intervention, 241,915 medication orders were placed, of which 25.6% generated one or more medication alerts; 5.3% of the alerts were accepted. During the postintervention period, 245,757 medication orders were placed of which 16.0% generated one or more medication alerts, a 37.5% relative decrease in alert rate (95% confidence interval [CI]: -38.4 to -36.8%), but only a 9.6% absolute decrease (95% CI: -9.4 to -9.9%). 7.4% of orders generating alerts were accepted postintervention, a 39.6% relative increase in acceptance rate (95% CI: 33.2-47.2%), but only a 2.1% absolute increase (95% CI: 1.8-2.4%). When only orders generating a single medication alert were considered, there was a 69.1% relative decrease in the number of orders generating DDI alerts, and an 85.7% relative increase in the acceptance rate (95% CI: 58.6-126.2%), though only a 1.8% absolute increase (95% CI: 1.3-2.3%). CONCLUSION: Eliminating intermediate severity DDI alerts resulted in a statistically significant decrease in alert burden and increase in the rate of medication alert acceptance, but alert acceptance remained low overall.

Does Use of Electronic Alerts for Systemic Inflammatory Response Syndrome (SIRS) to Identify Patients With Sepsis Improve Mortality?

PURPOSE: The objective of this study was to assess whether earlier antibiotic administration in patients with systemic inflammatory response syndrome (SIRS) and evidence of organ dysfunction identified through electronic alerts improves patient mortality. METHODS: This is a retrospective observational cohort study of adult patients admitted across 5 acute-care hospitals. Mortality, Premier CareScienceTM Analytics Expected Mortality Score, and clinical and demographic variables were obtained through the electronic medical record and Premier (Premier Healthcare Solutions, Inc, Charlotte NC) reports. Patients with 2 SIRS criteria and organ dysfunction were identified through an automated alert. Univariate and multivariate logistic regression was performed. RESULTS: Of those with SIRS and organ dysfunction, 8146 patients were identified through the electronic Best Practice Alert (BPA). Overall 30-day mortality rate was 8.7%. There was no significant association between time to antibiotic administration from BPA alert and mortality (P = 0.21) after adjusting for factors that could influence mortality, including age, heart rate, blood pressure, plasma lactate levels, creatinine, bilirubin levels, and the CareScienceTM Predicted Mortality Risk Score. Female gender (odds ratio [OR] 1.31, 95% confidence interval [CI] 1.06-1.63) and facility were also independently associated with mortality. CONCLUSION: The use of alerts in the electronic medical record may misclassify patients with SIRS as having sepsis. Time to antibiotic administration in patients meeting SIRS criteria and evidence of end-organ dysfunction through BPA alerts did not affect 30-day mortality rates across a health system. Patient severity of illness, gender, and facility also independently predicted mortality. There were higher rates of antibiotic use and Clostridioides difficile infection in patients with BPA alerts.

Development and Implementation of a Subcutaneous Insulin Clinical Decision Support Tool for Hospitalized Patients.

BACKGROUND: Insulin is one of the highest risk medications used in hospitalized patients. Multiple complex factors must be considered in determining a safe and effective insulin regimen. We sought to develop a computerized clinical decision support (CDS) tool to assist hospital-based clinicians in insulin management. METHODS: Adapting existing clinical practice guidelines for inpatient glucose management, a design team selected, configured, and implemented a CDS tool to guide subcutaneous insulin dosing in non-critically ill hospitalized patients at two academic medical centers that use the EpicCare® electronic medical record (EMR). The Agency for Healthcare Research and Quality (AHRQ) best practices in CDS design and implementation were followed. RESULTS: A CDS tool was developed in the form of an EpicCare SmartForm, which generates an insulin regimen by integrating information about the patient's body weight, diabetes type, home and hospital insulin requirements, and nutritional status. Total daily recommended insulin doses are distributed into respective basal and nutritional doses with a tailored correctional insulin scale. Preimplementation, several approaches were used to communicate this new tool to clinicians, including emails, lectures, and videos. Postimplementation, a support team was available to address user technical issues. Feedback from stakeholders has been used to continuously refine the tool. Inclusion of the programming in the EMR vendor's community library has allowed dissemination of the tool outside our institution. CONCLUSIONS: We have developed an EMR-based tool to guide SQ insulin dosing in non-critically ill hospitalized patients. Further studies are needed to evaluate adoption and clinical effectiveness of this intervention.

Trauma exposure acutely alters neural function during Pavlovian fear conditioning.

Posttraumatic stress disorder (PTSD) is associated with dysfunction of the neural circuitry that supports fear learning and memory processes. However, much of what is known about neural dysfunction in PTSD is based on research in chronic PTSD populations. Less is known about neural function that supports fear learning acutely following trauma exposure. Determining the acute effects of trauma exposure on brain function would provide new insight into the neural processes that mediate the cognitive-affective dysfunction associated with PTSD. Therefore, the present study investigated neural activity that supports fear learning and memory processes in recently Trauma-Exposed (TE) and Non-Trauma-Exposed (NTE) participants. Participants completed a Pavlovian fear conditioning procedure during functional magnetic resonance imaging (fMRI). During fMRI, participants' threat expectancy was continuously monitored. NTE participants showed greater threat expectancy during warning than safety cues, while no difference was observed in the TE group. This finding suggests TE participants overgeneralized the fear association to the safety cue. Further, only the TE group showed a negative relationship between fMRI signal responses within dorsomedial prefrontal cortex (PFC) and threat expectancy during safety cues. These results suggest the dorsomedial PFC mediates overgeneralization of learned fear as an acute result of trauma exposure. Finally, neural activity within the PFC and inferior parietal lobule showed a negative relationship with PTSD symptom severity assessed three months posttrauma. Thus, neural activity measured acutely following trauma exposure predicted future PTSD symptom severity. The present findings elucidate the acute effects of trauma exposure on cognitive-affective function and provide new insight into the neural mechanisms of PTSD.

Glutamate/glutamine concentrations in the dorsal anterior cingulate vary with Post-Traumatic Stress Disorder symptoms.

Trauma and stress-related disorders (e.g., Acute Stress Disorder; ASD and Post-Traumatic Stress Disorder; PTSD) that develop following a traumatic event are characterized by cognitive-affective dysfunction. The cognitive and affective functions disrupted by stress disorder are mediated, in part, by glutamatergic neural systems. However, it remains unclear whether neural glutamate concentrations, measured acutely following trauma, vary with ASD symptoms and/or future PTSD symptom expression. Therefore, the current study utilized proton magnetic resonance spectroscopy (1H-MRS) to investigate glutamate/glutamine (Glx) concentrations within the dorsal anterior cingulate cortex (ACC) of recently (i.e., within one month) traumatized individuals and non-traumatized controls. Although Glx concentrations within dorsal ACC did not differ between recently traumatized and non-traumatized control groups, a positive linear relationship was observed between Glx concentrations and current stress disorder symptoms in traumatized individuals. Further, Glx concentrations showed a positive linear relationship with future stress disorder symptoms (i.e., assessed 3 months post-trauma). The present results suggest glutamate concentrations may play a role in both acute and future post-traumatic stress symptoms following a traumatic experience. The current results expand our understanding of the neurobiology of stress disorder and suggest glutamate within the dorsal ACC plays an important role in cognitive-affective dysfunction following a traumatic experience.

Relative impact of a patient blood management program on utilization of all three major blood components.

BACKGROUND: Although patient blood management (PBM) programs clearly reduce transfusion overuse, the relative impact on red blood cell (RBC), plasma, and platelet (PLT) utilization is unclear. STUDY DESIGN AND METHODS: A retrospective analysis of electronic records was conducted at a medium-sized academic hospital to assess blood utilization for all inpatients admitted during 1-year periods before (n = 20,531) and after (n = 19,477) PBM efforts began in September 2014. Transfusion guideline compliance and overall utilization were assessed for RBCs, plasma, and PLTs. The primary PBM efforts included education on evidence-based transfusion guidelines, decision support in the computerized provider order entry system, and distribution of provider-specific reports showing comparison to peers for guideline compliance. Cost avoidance was determined by two methods (acquisition cost and activity-based cost), and clinical outcomes were compared during the two periods. RESULTS: For RBCs, orders outside hospital guidelines decreased (from 23.9% to 17.1%, p < 0.001), and utilization decreased by 12% (p < 0.035). For plasma and PLTs, both orders outside guidelines and utilization changed minimally. Overall cost avoidance was $181,887/year by acquisition cost (and from $582,039 to $873,058/year by activity-based cost), 93% of which was attributed to reduction in RBC utilization. Length of stay, morbidity, and mortality were unchanged. CONCLUSIONS: Our findings demonstrate a greater opportunity for reducing RBC compared to plasma and PLT utilization. A properly implemented PBM program has potential to reduce unnecessary transfusions and their associated risk and costs, without compromising clinical outcomes.

Impact of an educational intervention on the frequency of daily blood test orders for hospitalized patients.

OBJECTIVES: During hospitalizations, blood is drawn for diagnostic laboratory tests to help guide patient care. Often, blood tests continue to be ordered even in the face of clinical and laboratory stability. Blood draws are painful and costly, and they may be associated with anemia. We hypothesized that provider education could reduce the frequency of daily blood tests ordered for hospitalized patients. METHODS: During a 2-month intervention period, internal medicine providers were educated through flyers displayed in providers' offices and periodic email communications reminding them to order daily blood tests only if the results would change patient care. Two-month preintervention data from 982 patients and 2-month postintervention data from 988 patients were analyzed. The primary outcome measured was the number of daily blood tests ordered per patient per day. RESULTS: Mean orders of CBC decreased from 1.46 to 1.37 tests per patient per day (P < .05) after the intervention. Basic metabolic panel orders were reduced from 0.91 to 0.83 tests per patient per day (P < .05). Cost analyses showed a reduction of $6.33 per patient day based on the decrease in the number of daily laboratory tests ordered. CONCLUSIONS: Provider education and reminders can reduce the frequency of daily blood tests ordered by providers for hospitalized patients. This can decrease health care costs and may reduce the risk of complications such as anemia.

Factors associated with medication warning acceptance for hospitalized adults.

BACKGROUND: Computerized provider order entry (CPOE) systems can warn clinicians ordering medications about potential allergic or adverse reactions, duplicate therapy, and interactions with other medications. Clinicians frequently override these warnings. Understanding the factors associated with warning acceptance should guide revisions to these systems. OBJECTIVE: Increase understanding of the factors associated with medication warning acceptance. DESIGN: Retrospective study of all single-medication warnings generated in a CPOE system from October 2009 through April 2010. SETTING: Academic medical center. PATIENTS: All adult non-intensive care unit patients hospitalized during the study period. RESULTS: A total of 40,391 medication orders generated a single-medication warning during the 7-month study period. Of these warnings, 47% were duplicate warnings, 47% interaction warnings, 6% allergy warnings, 0.1% adverse reaction warnings, and 9.8% were repeated for the same patient, medication, and provider. Only 4% of warnings were accepted. In multivariate analysis, warning acceptance was positively associated with male patient gender, admission to a service other than internal medicine, caregiver status other than resident, parenteral medications, lower numbers of warnings, and allergy or adverse reaction warning types. Older patient age, longer length of stay, inclusion on the Institute for Safe Medication Practice's List of High Alert Medications, and interaction warning type were all negatively associated with warning acceptance. CONCLUSIONS: Medication warnings are rarely accepted. Acceptance is more likely when the warning is infrequently encountered, and least likely when it is potentially most important. Warning systems should be redesigned to increase their effectiveness for the sickest patients, the least experienced physicians, and the medications with the greatest potential to cause harm.

Reducing excess cardiac biomarker testing at an academic medical center.

BACKGROUND: Elimination of wasteful diagnostic testing will improve value for the United States health care system. OBJECTIVE: Design and implement a multimodal intervention to improve evidence-based ordering of cardiac biomarkers for the diagnosis of acute coronary syndrome (ACS). DESIGN: Interrupted times series. SUBJECTS: A total of 60,494 adult inpatient admissions from January 2009 through July 2011 (pre-intervention) and 24,341 admissions from November 2011 through October 2012 (post-intervention) at an academic medical center in Baltimore, Maryland. INTERVENTION: Multimodal intervention introduced August through October 2011 that included dissemination of an institutional guideline and changes to the computerized provider order entry system. MAIN MEASURES: The primary outcome was percentage of patients with guideline-concordant ordering of cardiac biomarkers, defined as three or fewer troponin tests and zero CK-MB tests in patients without a diagnosis of ACS. Secondary outcomes included counts of tests ordered per patient, incidence of diagnosis of ACS, and estimated change in charges for cardiac biomarker tests in the post-intervention period. KEY RESULTS: Twelve months following the intervention, we estimated that guideline-concordant ordering of cardiac biomarkers increased from 57.1 % to 95.5 %, an absolute increase of 38.4 % (95 % CI, 36.4 % to 40.4 %). We estimated that the intervention led to a 66 % reduction in the number of tests ordered, and a $1.25 million decrease in charges over the first year. At 12 months, there was an estimated absolute increase in incidence of primary diagnosis of ACS of 0.3 % (95 % CI, 0.0 % to 0.5 %) compared with the expected baseline rate. CONCLUSIONS: We implemented a multimodal intervention that significantly increased guideline-concordant ordering of cardiac biomarker testing, leading to substantial reductions in tests ordered without impacting diagnostic yield. A trial of this approach at other institutions and for other diagnostic tests is warranted and if successful, would represent a framework for eliminating wasteful diagnostic testing.
