Reversible O-H Bond Activation by Tripodal tris(Nitroxide) Aluminum and Gallium Complexes.

Herein, we report the preparation and characterization of the Group 13 metal complexes of a tripodal tris(nitroxide)-based ligand, designated (TriNOx3-)M (M = Al (1), Ga (2), In (3)). Complexes 1 and 2 both activate the O-H bond of a range of alcohols spanning a ∼10 pKa unit range via an element-ligand cooperative pathway to afford the zwitterionic complexes (HTriNOx2-)M-OR. Structures of these alcohol adduct products are discussed. We demonstrate that the thermodynamic and kinetic aspects of the reactions are both influenced by the identity of the metal, with 1 having higher reaction equilibrium constants and proceeding at a faster rate relative to 2 for any given alcohol. These parameters are also influenced by the pKa of the alcohol, with more acidic alcohols reacting both to more completion and faster than their less acidic counterparts. Possible mechanistic pathways for the O-H activation are discussed.

Predicting Serious Bacterial Infections Among Hypothermic Infants in the Emergency Department.

BACKGROUND: There is insufficient evidence to guide the initial evaluation of hypothermic infants. We aimed to evaluate risk factors for serious bacterial infections (SBI) among hypothermic infants presenting to the emergency department (ED). METHODS: We conducted a multicenter case-control study among hypothermic (rectal temperature <36.5°C) infants ≤90 days presenting to the ED who had a blood culture collected. Our outcome was SBI (bacteremia, bacterial meningitis, and/or urinary tract infection). We performed 1:2 matching. Historical, physical examination and laboratory covariables were determined based on the literature review from febrile and hypothermic infants and used logistic regression to identify candidate risk factors. RESULTS: Among 934 included infants, 57 (6.1%) had an SBI. In univariable analyses, the following were associated with SBI: age > 21 days, fever at home or in the ED, leukocytosis, elevated absolute neutrophil count, thrombocytosis, and abnormal urinalysis. Prematurity, respiratory distress, and hypothermia at home were negatively associated with SBI. The full multivariable model exhibited a c-index of 0.91 (95% confidence interval: 0.88-0.94). One variable (abnormal urinalysis) was selected for a reduced model, which had a c-index of 0.82 (95% confidence interval: 0.75-0.89). In a sensitivity analysis among hypothermic infants without fever (n = 22 with SBI among 116 infants), leukocytosis, absolute neutrophil count, and abnormal urinalysis were associated with SBI. CONCLUSIONS: Historical, examination, and laboratory data show potential as variables for risk stratification of hypothermic infants with concern for SBI. Larger studies are needed to definitively risk stratify this cohort, particularly for invasive bacterial infections.

Clinician Management Practices for Infants With Hypothermia in the Emergency Department.

BACKGROUND: Young infants with serious bacterial infections (SBI) or herpes simplex virus (HSV) infections may present to the emergency department (ED) with hypothermia. We sought to evaluate clinician testing and treatment preferences for infants with hypothermia. METHODS: We developed, piloted, and distributed a survey of ED clinicians from 32 US pediatric hospitals between December 2022 to March 2023. Survey questions were related to the management of infants (≤60 days of age) with hypothermia in the ED. Questions pertaining to testing and treatment preferences were stratified by age. We characterized clinician comfort with the management of infants with hypothermia. RESULTS: Of 1935 surveys distributed, 1231 (63.6%) were completed. The most common definition of hypothermia was a temperature of ≤36.0°C. Most respondents (67.7%) could recall caring for at least 1 infant with hypothermia in the previous 6 months. Clinicians had lower confidence in caring for infants with hypothermia compared with infants with fever (P < .01). The proportion of clinicians who would obtain testing was high in infants 0 to 7 days of age (97.3% blood testing for SBI, 79.7% for any HSV testing), but declined for older infants (79.3% for blood testing for SBI and 9.5% for any HSV testing for infants 22-60 days old). A similar pattern was noted for respiratory viral testing, hospitalization, and antimicrobial administration. CONCLUSIONS: Testing and treatment preferences for infants with hypothermia varied by age and frequently reflected observed practices for febrile infants. We identified patterns in management that may benefit from greater research and implementation efforts.

Development of cross-service training and job performance criterion measures for the U.S. Military.

As part of an effort to provide standardized criterion measures across the Armed Services, the current research effort developed a set of service-wide criterion measures for first-term enlisted personnel using a recently developed model of cross-service job performance. Two concurrent work streams developed criterion measures which provide complete construct coverage of the cross-service performance model. Using existing service-specific instruments, methods for development of the Cross-Service Situational judgment Test (CSSJT), the Cross-Service Job Performance Ratings Scales (CSPRS), and two cross-service self-report measures (end of training and in unit surveys) are described and discussed.

The reliability and validity of the TBI-CareQOL system in four diverse caregiver groups.

PURPOSE: Establishing the psychometric reliability and validity of new measures is an ongoing process. More work is needed in to confirm the clinical utility of the TBI-CareQOL measurement development system in both an independent cohort of caregivers of traumatic brain injury (TBI), as well as in additional caregiver groups. METHODS: An independent cohort of caregivers of people with TBI (n = 139), as well as three new diverse caregiver cohorts (n = 19 caregivers of persons with spinal cord injury, n = 21 caregivers for persons with Huntington disease, and n = 30 caregivers for persons with cancer), completed 11 TBI-CareQOL measures (caregiver strain; caregiver-specific anxiety; anxiety; depression; anger; self-efficacy; positive affect and well-being; perceived stress; satisfaction with social roles and activities; fatigue; sleep-related impairment), as well as two additional measures to examine convergent and discriminant validity (PROMIS Global Health; the Caregiver Appraisal Scale). RESULTS: Findings support the internal consistency reliability (all alphas > 0.70 with the vast majority being > 0.80 across the different cohorts) of the TBI-CareQOL measures. All measures were free of ceiling effects, and the vast majority were also free of floor effects. Convergent validity was supported by moderate to high correlations between the TBI-CareQOL and related measures, while discriminant validity was supported by low correlations between the TBI-CareQOL measures and unrelated constructs. CONCLUSION: Findings indicate that the TBI-CareQOL measures have clinical utility in caregivers of people with TBI, as well as in other caregiver groups. As such, these measures should be considered as important outcome measures for clinical trials aiming to improve caregiver outcomes.

Temperature threshold in the screening of bacterial infections in young infants with hypothermia.

BACKGROUND: Young infants with hypothermia presenting to the emergency department (ED) are at risk for serious bacterial infections (SBI), however there is no consensus temperature to prompt evaluation for SBI among these children. We sought to statistically derive a temperature threshold to guide detection of SBI in young infants with hypothermia presenting to the ED. METHODS: We performed a cross-sectional study of infants ≤90 days old presenting to four academic paediatric EDs in the United States of America from January 2015 through December 2019 with a rectal temperature of ≤36.4°C. Our primary outcomes were SBI, defined as urinary tract infection (UTI), bacteraemia and/or bacterial meningitis, and invasive bacterial infections (IBI, limited to bacteraemia and/or bacterial meningitis). We constructed receiver operating characteristic (ROC) curves to evaluate an optimally derived cutpoint for minimum ED temperature and presence of SBI or IBI. RESULTS: We included 3376 infants, of whom SBI were found in 62 (1.8%) and IBI in 16 (0.5%). The most common infection identified was Escherichia coli UTI. Overall, cohort minimum median temperature was 36.2°C (IQR 36.0°C-36.4°C). Patients with SBI and IBI had lower median temperatures, 35.8°C (IQR 35.8°C-36.3°C) and 35.4°C (IQR 35.7°C-36.3°C), respectively, compared with those without corresponding infections (both p<0.05). Using an outcome of SBI, the area under the ROC curve (AUROC) was 61.0% (95% CI 54.1% to 67.9%). At a cutpoint of 36.2°C, sensitivity was 59.7% and specificity was 59.2%. When using an outcome of IBI, the AUROC was 65.9% (95% CI 51.1% to 80.6%). Using a cutpoint of 36.1°C in this model resulted in a sensitivity of 68.8% and specificity of 60.1%. CONCLUSION: Young infants with SBI and IBI presented with lower temperatures than infants without infections. However, there was no temperature threshold to reliably identify SBI or IBI. Further research incorporating clinical and laboratory parameters, in addition to temperature, may help to improve risk stratification for these vulnerable patients.

Biomarkers and their association with bacterial illnesses in hypothermic infants.

OBJECTIVES: To describe the association of biomarkers with serious bacterial infection (SBI; urinary tract infection [UTI], bacteremia and/or bacterial meningitis) in hypothermic infants presenting to the emergency department (ED). METHODS: We performed a cross sectional study in four academic pediatric EDs from January 2015 through December 2019, including infants ≤90 days old presenting with a rectal temperature of ≤36.4 °C. We constructed receiver operating characteristic (ROC) curves to evaluate the accuracy of blood biomarkers including white blood cell count (WBC), absolute neutrophil count (ANC) and platelets for identifying SBI, with exploratory analyses evaluating procalcitonin and band counts. RESULTS: Among 850 included infants (53.5% males; median days of age 13 [IQR 5-58 days]), SBI were found in 55 (6.5%). For infants with SBI, the area under the curve (AUC; 95% confidence interval) for WBC was 0.70 (0.61-0.78) with sensitivity 0.64 (0.50-0.74) and specificity 0.77 (0.74-0.80). The AUC for ANC was 0.77 (0.70-0.84) with sensitivity 0.69 (0.55-0.81) and specificity 0.77 (0.74-0.8). For platelets, the AUC was 0.6 (0.52-0.67) with sensitivity 0.73 (0.59-0.84) and specificity 0.5 (0.46-0.53). Both the WBC and ANC were minimally accurate for identifying hypothermic infants with SBI. When looking at the accuracy of these biomarkers for identifying invasive bacterial infection (IBI; bacteremia and/or bacterial meningitis), ANC again showed minimal accuracy with an AUC of 0.70 (0.55-0.85). CONCLUSIONS: Biomarkers commonly used as part of an infectious workup are generally poor at identifying SBI in hypothermic infants. Our findings from this cohort of hypothermic infants are similar to those reported from febrile infants, suggesting similarities in the bioresponse to infection between hypothermic and febrile infants. Additional research is required to improve risk stratification for hypothermic infants, and to better guide evaluation and management.

Initial Evidence for Reliable and Valid Use of Scores on the 8-Item Econ-QOL Short Form to Measure Economic Quality of Life in Caregivers of Persons With Traumatic Brain Injury.

OBJECTIVE: To provide reliability and validity data to support the clinical utility of Economic Quality of Life Measure (Econ-QOL) scores in caregivers of civilians and service members/veterans with traumatic brain injury (TBI). DESIGN: Cross-sectional survey study. SETTING: Three academic medical centers and a Veterans Affairs treatment facility. PARTICIPANTS: 376 caregivers of civilians (n=213) and service members/veterans (n=163) with TBI (N=376). INTERVENTIONS: N/A. MAIN OUTCOME MEASURES: Econ-QOL and several patient-reported outcome measures (Traumatic Brain Injury Caregiver Quality of Life Caregiver-Specific Anxiety and Caregiver Strain, Patient-Reported Outcomes Measurement Information System sleep-related impairment, Neurological Quality of Life Measurement System positive affect and well-being) and measures of financial status (self-reported income). RESULTS: Internal consistency reliability of the Econ-QOL Short Form scores were excellent (all Cronbach's alphas ≥.92). There were no floor or ceiling effects for scores. There was evidence of convergent and discriminant validity, with the Econ-QOL scores having the strongest relationships with self-reported income (convergent validity evidence) and weak relationships with the other measures (discriminant validity evidence). Individuals with scores that were "below or possibly below" the poverty line (according to 2016 federal government poverty level thresholds) reported worse economic quality of life relative to those individuals who were definitely above the poverty line, supporting known-groups validity. CONCLUSIONS: This article establishes the clinical utility of scores on the Econ-QOL Short Form in caregivers of persons with TBI and provides evidence that it is valid and appropriate to use such scores not only in a variety of different disability populations (eg, spinal cord injury, stroke) but also in caregivers.

An app-based just-in-time-adaptive self-management intervention for care partners: The CareQOL feasibility pilot study.

PURPOSE/OBJECTIVE: The primary objective of this study was to establish the feasibility and acceptability of an intensive data collection protocol that involves the delivery of a personalized just-in-time adaptive intervention (JITAI) in three distinct groups of care partners (care partners of persons with spinal cord injury [SCI], Huntington's disease [HD], or hematopoietic cell transplantation [HCT]). RESEARCH METHOD/DESIGN: Seventy care partners were enrolled in this study (n = 19 SCI; n = 21 HD, n = 30 HCT). This three-month (90 day) randomized control trial involved wearing a Fitbit to track sleep and steps, providing daily reports of health-related quality of life (HRQOL), and completing end of month HRQOL surveys. Care partners in the JITAI group also received personalized pushes (i.e., text-based phone notifications that include brief tips or suggestions for improving self-care). At the end of three-months, care partners in both groups completed a feasibility and acceptability questionnaire. RESULTS: Most (98.6%) care partners completed the study, average compliance was 88% for daily HRQOL surveys, 96% for daily steps, and 85% for daily sleep (from wearing the Fitbit), and all monthly surveys were completed with the exception of one missed 3-month assessment. The acceptability of the protocol was high; ratings exceeded 80% agreement for the different elements of the study. Improvements were seen for the majority of the HRQOL measures. There was no evidence of measurement reactivity. CONCLUSIONS/IMPLICATIONS: Findings provide strong support for the acceptability and feasibility of an intensive data collection protocol that involved the administration of a JITAI. Although this trial was not powered to establish efficacy, findings indicated improvements across a variety of different HRQOL measures (~1/3 of which were statistically significant).

Mars Oxygen ISRU Experiment (MOXIE)-Preparing for human Mars exploration.

MOXIE [Mars Oxygen In Situ Resource Utilization (ISRU) Experiment] is the first demonstration of ISRU on another planet, producing oxygen by solid oxide electrolysis of carbon dioxide in the martian atmosphere. A scaled-up MOXIE would contribute to sustainable human exploration of Mars by producing on-site the tens of tons of oxygen required for a rocket to transport astronauts off the surface of Mars, instead of having to launch hundreds of tons of material from Earth's surface to transport the required oxygen to Mars. MOXIE has produced oxygen seven times between landing in February 2021 and the end of 2021 and will continue to demonstrate oxygen production during night and day throughout all martian seasons. This paper reviews what MOXIE has accomplished and the implications for larger-scale oxygen-producing systems.

Improving outcomes for care partners of persons with traumatic brain injury: Protocol for a randomized control trial of a just-in-time-adaptive self-management intervention.

Informal family care partners of persons with traumatic brain injury (TBI) often experience intense stress resulting from their caregiver role. As such, there is a need for low burden, and easy to engage in interventions to improve health-related quality of life (HRQOL) for these care partners. This study is designed to evaluate the effectiveness of a personalized just-in-time adaptive intervention (JITAI) aimed at improving the HRQOL of care partners. Participants are randomized either to a control group, where they wear the Fitbit® and provide daily reports of HRQOL over a six-month (180 day) period (without the personalized feedback), or the JITAI group, where they wear the Fitbit®, provide daily reports of HRQOL and receive personalized self-management pushes for 6 months. 240 participants will be enrolled (n = 120 control group; n = 120 JITAI group). Outcomes are collected at baseline, 1-, 2-, 3-, 4-, 5- & 6-months, as well as 3- and 6-months post intervention. We hypothesize that the care partners who receive the intervention (JITAI group) will show improvements in caregiver strain (primary outcome) and mental health (depression and anxiety) after the 6-month (180 day) home monitoring period. Participant recruitment for this study started in November 2020. Data collection efforts should be completed by spring 2025; results are expected by winter 2025. At the conclusion of this randomized control trial, we will be able to identify care partners at greatest risk for negative physical and mental health outcomes, and will have demonstrated the efficacy of this JITAI intervention to improve HRQOL for these care partners.

An App-Based Just-in-Time Adaptive Self-management Intervention for Care Partners (CareQOL): Protocol for a Pilot Trial.

BACKGROUND: Care partners (ie, informal family caregivers) of individuals with health problems face considerable physical and emotional stress, often with a substantial negative impact on the health-related quality of life (HRQOL) of both care partners and care recipients. Given that these individuals are often overwhelmed by their caregiving responsibilities, low-burden self-management interventions are needed to support care partners to ensure better patient outcomes. OBJECTIVE: The primary objective of this study is to describe an intensive data collection protocol that involves the delivery of a personalized just-in-time adaptive intervention that incorporates passive mobile sensor data feedback (sleep and activity data from a Fitbit [Fitbit LLC]) and real time self-reporting of HRQOL via a study-specific app called CareQOL (University of Michigan) to provide personalized feedback via app alerts. METHODS: Participants from 3 diverse care partner groups will be enrolled (care partners of persons with spinal cord injury, care partners of persons with Huntington disease, and care partners of persons with hematopoietic cell transplantation). Participants will be randomized to either a control group, where they will wear the Fitbit and provide daily reports of HRQOL over a 3-month (ie, 90 days) period (without personalized feedback), or the just-in-time adaptive intervention group, where they will wear the Fitbit, provide daily reports of HRQOL, and receive personalized push notifications for 3 months. At the end of the study, participants will complete a feasibility and acceptability questionnaire, and metrics regarding adherence and attrition will be calculated. RESULTS: This trial opened for recruitment in November 2020. Data collection was completed in June 2021, and the primary results are expected to be published in 2022. CONCLUSIONS: This trial will determine the feasibility and acceptability of an intensive app-based intervention in 3 distinct care partner groups: care partners for persons with a chronic condition that was caused by a traumatic event (ie, spinal cord injury); care partners for persons with a progressive, fatal neurodegenerative disease (ie, Huntington disease); and care partners for persons with episodic cancer conditions that require intense, prolonged inpatient and outpatient treatment (persons with hematopoietic cell transplantation).

Association of physical and mental symptoms with cognition in people with spinal cord injury.

PURPOSE/OBJECTIVE: To examine the association between physical and mental symptoms and cognition in people with spinal cord injury. Research Method/Design: One hundred seventy-four community-dwelling adults with spinal cord injury completed several self-reported measures of health-related quality of life (Patient-Reported Outcomes Measurement Information System [PROMIS] Cognitive Abilities, Anxiety, Depression, Fatigue, and Pain Intensity) as well as a traditional neuropsychological assessment (six tests that included assessments of processing speed, working memory, memory, executive function, and attention). A series of multivariable linear regressions were used to test for associations between physical and mental symptoms and the seven ratings of cognition (i.e., scores on PROMIS Cognitive Abilities, as well as the six scores from the neuropsychological tests) after controlling for age, gender, education, and injury classification. RESULTS: There was generally no association between symptom measures and neuropsychological test performance with one exception: Greater pain was associated with poorer performance on attention. However, anxiety and fatigue were associated with lower self-perceived cognitive function. Among those individuals with evidence of cognitive impairment in at least one cognitive domain, anxiety was also associated with lower working memory score, and fatigue was associated with lower delayed memory performance. CONCLUSIONS/IMPLICATIONS: While the associations between pain and cognitive performance are consistent with general literature, the absence of a relationship between other symptoms (i.e., depression and fatigue) and cognitive performance was somewhat more surprising. Similarly, the associations between anxiety and fatigue with perceived cognitive function are consistent with the general literature, yet the absence of a relationship with depression was somewhat more surprising. Future work is needed to replicate these findings. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

The association between medication use and cognitive performance in people with SCI.

PURPOSE/OBJECTIVE: Polypharmacy is common in people with spinal cord injury (SCI). Given the high rates of medication use, and the complicated side effect profile of many of the medications that are regularly prescribed in people with SCI, we were interested in the association between the use of different classes of medications and cognitive function in these individuals. Research Method/Design: One-hundred and 73 people with SCI participated in an observational study. Self-reported medications were provided by participants. Participants also completed several cognitive tests designed to capture multiple aspects of cognition (processing speed, attention, working memory, learning, free-recall memory, delayed free recall memory, executive function), as well as a self-report measure that captures participant perceptions of cognitive function. A series of multivariable linear regressions were used to test for associations between medications and the seven measures of cognition. RESULTS: In general, there was not a robust relationship between medication use and cognitive function; the sole exception was an association between opioid use and subjective cognitive function. There was some preliminary support for an association between medication use, especially benzodiazepine and opioid analgesic use, and poorer cognitive performance. Specifically: Opioid analgesic use was associated with slowed processing speed, worse attention, poorer working memory, poorer executive function and more subjective cognitive complaints; benzodiazepine use was associated with slower processing speed, poorer working memory, and worse executive function; anticonvulsant use was related to worse delayed free recall memory; and the number of medication categories a person with SCI was taking was related to slower processing speed, and worse subjective cognitive function. Antidepressant, cannabis, skeletal muscle relaxant, sedative and stimulant use were not significantly related to cognitive performance, nor to subjective reports of cognitive function. CONCLUSIONS/IMPLICATIONS: Findings did not support a strong relationship between medication use and cognitive function in people with SCI. There is some preliminary support for an association between benzodiazepine use and cognitive performance, but this needs to be confirmed in future research.

Increasing Cardiac Rehabilitation Participation Through a "Nearer to Home" Patient Referral Program.

PURPOSE: Time to travel to cardiac rehabilitation (CR) centers is a barrier to participation, and tertiary referral centers often care for patients living at a substantial distance. We sought to determine the impact of referring eligible patients to CR centers closer to home or workplace on overall participation rate. METHODS: An observational review was conducted in patients from a large cardiovascular program who were referred to CR (January 1, 2015, through December 31, 2016). Those declining participation due to distance from their home were identified and provided coordinated referral to a CR program they chose near their home or workplace. RESULTS: Of the 2912 patients referred to CR, 673 (23%) participated and 1900 declined due to distance. Contact was made in 2017 with 1237 of the 1900 of whom 1083 recalled a discussion of distance referral and completed the phone survey. Participants mean age was 64 yr, predominantly White (88%), male (65%), married (66%), and 70% had ≥ comorbidity. Out of the 1083 referred to a local CR program, 78% reported attending. Of those who attended CR, 55% (469/849) would not have attended had they not been referred to a program closer to their home or workplace. Overall participation increased from 23% to >50% of those referred from our institution. CONCLUSIONS: Coordinating CR referrals from the discharging facility to facilities closer to home or workplace is an effective means for increasing participation. The very low-cost effort has the potential to have a very meaningful impact on the long-term outcome of cardiovascular patients.

Barriers to integrating direct oral anticoagulants into anticoagulation clinic care: A mixed-methods study.

BACKGROUND: Outpatient anticoagulation clinics were initially developed to care for patients taking vitamin K antagonists such as warfarin. There has not been a systematic evaluation of the barriers and facilitators to integrating direct oral anticoagulant (DOAC) care into outpatient anticoagulation clinics. METHODS: We performed a mixed methods study consisting of an online survey of anticoagulation clinic providers and semi-structured interviews with anticoagulation clinic leaders and managers between March and May of 2017. Interviews were transcribed and coded, exploring for themes around barriers and facilitators to DOAC care within anticoagulation clinics. Survey questions pertaining to the specific themes identified in the interviews were analyzed using summary statistics. RESULTS: Survey responses were collected from 159 unique anticoagulation clinics and 20 semi-structured interviews were conducted. Three primary barriers to DOAC care in the anticoagulation clinic were described by the interviewees: (a) a lack of provider awareness for ongoing monitoring and services provided by the anticoagulation clinic; (b) financial challenges to providing care to DOAC patients in an anticoagulation clinic model; and (c) clinical knowledge versus scope of care by the anticoagulation staff. These themes linked to three key areas of variation, including: (a) the size and hospital affiliation of the anticoagulation clinic; (b) the use of face-to-face versus telephone-based care; and (c) the use of nurses or pharmacists in the anticoagulation clinic. CONCLUSIONS: Anticoagulation clinics in the United States experience important barriers to integrating DOAC care. These barriers vary based on the clinic size, model for warfarin care, and staff credentials (nursing or pharmacy).

Periprocedural Antithrombotic Management from a Patient Perspective: A Qualitative Analysis.

BACKGROUND: Periprocedural antithrombotic medication management is a complex, often confusing process for patients and their providers. Communication difficulties often lead to suboptimal medication management, resulting in delayed or canceled procedures. METHODS: We conducted telephone surveys with patients taking chronic antithrombotic medications who had recently undergone an endoscopy procedure. In the survey, we sought to better understand the periprocedural process for patients taking antithrombotic medications. We conducted a content analysis of patients' unstructured responses from the periprocedural patient phone calls. We used a multistep group coding process to analyze responses. Relationships between different themes and categories were analyzed using original quotes and retrieving thematic segments from the transcripts. RESULTS: The survey was administered to 81 patients; 74/81 respondents (91%) said they understood the plan to manage their antithrombotics, but 21/81 respondents (26%) were not completely satisfied with the coordination, communication, and management of their medications. Five primary themes emerged from the content analysis as patient-centered design features affecting periprocedural care: (1) patients require accurate and timely information; (2) a patient's prior experience with antithrombotic therapy affects their understanding of the process; (3) patients prefer receiving their information from a single source, and (4) also prefer different methods of instruction; (5) finally, patients expect their clinician(s) to be available through the periprocedural management process. CONCLUSION: To optimize the periprocedural medication management communication process, patients desire timeliness, accuracy, and adaptiveness to prior patient experience while offering a single, consistently available point of contact.

Out-of-range INR results lead to increased health-care utilization in four large anticoagulation clinics.

BACKGROUND: The impact on health-care costs and utilization of a single out-of-range (OOR) INR value not associated with bleeding or thromboembolic complication among chronic warfarin-treated patients is not well described. METHODS: At four large phone-based anticoagulation clinics (total 14 948 patients), warfarin-treated patients with atrial fibrillation (AF) or venous thromboembolism were retrospectively propensity matched into an OOR INR group (n = 116) and a control group (n = 58). Types and frequency of contacts (eg, phone, voicemail, facsimile) and personnel involved were identified. A prospective time study analysis of 59 OOR and 92 control patients was performed over 8.5 days to record the time required to care for these patients. 2016 USD cost estimates were generated from average salaries. RESULTS: OOR and in-range INR patients experienced an average of 4.2 and 3.2 (P < .001) INR lab draws until two sequential tests were in range. OOR INR patients required an average of 5.3 interactions with the anticoagulation clinic vs 3.7 for in-range INR patients (P < .001). OOR INR patients more often required phone calls, fewer mailed letters, and more often required multiple types of contact than in-range INR patients. In the prospective analysis, total median time involved for each OOR INR value was 5.1 minutes (IQR 3.7-9.5) vs 2.9 minutes (IQR 1.8-5.8) for control INR values (P < .001). At the clinic level, OOR INR values were associated with a yearly staff cost of $17 938 (IQR $8969-$31 391). CONCLUSIONS: We quantified the amount of extra anticoagulation staff effort required to manage warfarin-treated patients who experience a single OOR INR value without bleeding or thromboembolic complications, which leads to higher healthcare utilization costs.
