Postoperative Opioid-Prescribing Practice in Limb Preservation Surgery.

BACKGROUND: Limb preservation surgery affects more than 100,000 Americans annually. Current postoperative pain management prescribing practices of podiatric physicians in the United States are understudied. We examined prescribing practices for limb preservation surgery to identify prescriber characteristics' that may be associated with postoperative opioid-prescribing practices. METHODS: We administered an anonymous online questionnaire consisting of five patient scenarios with limb preservation surgery commonly performed by podiatric physicians. Respondents provided information about their prescription choice for each surgery. Basic provider demographics were collected. We developed linear regression models to identify the strength and direction of association between prescriber characteristics and quantity of postoperative opioid "pills" (dosage units) prescribed at surgery. Logistic regression models were used to identify the odds of prescribing opioids for each scenario. RESULTS: One hundred fifteen podiatric physicians completed the survey. Podiatric physicians reported using regional nerve blocks 70% to 88% of the time and prescribing opioids 43% to 67% of the time across all scenarios. Opioids were more commonly prescribed than nonsteroidal anti-inflammatory drugs and anticonvulsants. Practicing in the Northeast United States was a significant variable in linear regression (P = .009, a decrease of 9-10 dosage units) and logistic regression (odds ratio, 0.23; 95% confidence interval, 0.07-0.68; P = .008) models for the transmetatarsal amputation scenario. CONCLUSIONS: Prescribing practice variation exists in limb preservation surgery by region. Podiatric physicians reported using preoperative regional nerve blocks more than prescribing postoperative opioids for limb preservation surgeries. Through excess opioid prescribing, the diabetes pandemic has likely contributed to the US opioid epidemic. Podiatric physicians stand at the intersection of these two public health crises and are equipped to reduce their impact via preventive foot care and prescribing nonopioid analgesics when warranted.

Prostate biopsy sepsis prevention: external validation of an alcohol needle washing protocol.

PURPOSE: Transrectal ultrasound-guided prostate biopsy (TRUS-Bx) is associated with a 1-8% risk of post-biopsy sepsis (PBS). A recent study described an isopropyl alcohol needle washing protocol that significantly decreased PBS rates. The current study examined the efficacy of this technique in our clinic population. MATERIALS AND METHODS: Data were reviewed for 1250 consecutive patients undergoing TRUS-Bx at the Charlie Norwood VA Medical Center from January 2017 to January 2023. Needle washing was adopted in February 2021. Complications occurring within 30 days after TRUS-Bx were recorded. RESULTS: There were 912 patients in group 1 (without needle washing) and 338 in group 2 (with needle washing). Groups had equivalent demographic features, and men of African descent comprised 70% of patients. Standard 12 core biopsies were done in 83% and 82% in groups 1 and 2, respectively (p = 0.788). Total complication rates were 4% and 2% in groups 1 and 2, respectively (p = 0.077). There were 13 sepsis events in group 1 (1.4%) and none in group 2 (p = 0.027). Clavien-Dindo Grade I-III complications occurred in 25 (2.7%) and 7 (2.1%) patients in groups 1 and 2, respectively (p = 0.505). Standard antibiotic prophylaxis (PO fluoroquinolone and IM gentamicin) was given in 80% and 86% of patients in groups 1 and 2, respectively (p = 0.030). Subset analysis limited to patients who received standard prophylaxis showed a significant difference in sepsis rates (1.5% vs 0%; p = 0.036). CONCLUSIONS: Adoption of isopropyl alcohol needle washing was associated with a significant decrease in PBS events.

Communicating visit information to family caregivers: How does method matter? A national survey.

OBJECTIVES: The clinic visit is a critical point of contact for family caregivers. However, only 37% of family caregivers are able to accompany patients to visits. When they cannot attend, caregivers receive visit information to assist with their caregiving. However, little is known about how method of receiving information from clinic visits is associated with important caregiver outcomes. This study sought to determine whether mode of receiving clinic visit information (speaking with the patient, attending the visit, or using an after-visit summary [AVS]) was associated with changes in caregiver burden, caregiver preparedness, and the positive aspects of caregiving. METHODS: Cross-sectional web-based survey of a national sample of adult family caregivers. Multiple linear regression models determined associations between communication modes and caregivers' burden, preparedness, and positive aspects of caregiving, adjusting for sociodemographic covariates. RESULTS: Respondents (N = 340) were mostly male (58%), White (59%), ranged from 18 to 85 years old, and supported patients with conditions including diabetes, dementia, and cancer. Speaking with patients was associated with increases in positive aspects of caregiving (95% CI = 2.01, 5.42) and an AVS was associated with increases in positive aspects of caregiving (95% CI = 0.4, 3.56) and preparedness for caregiving (95% CI = 0.61, 3.15). Using any method of receiving information from visits was associated with the greatest increase in preparedness, compared to not receiving visit information. We did not observe an association between method of communication and caregiver burden. SIGNIFICANCE OF RESULTS: Method of communicating visit information is associated with improvements in caregiver preparedness and the positive aspects of caregiving, though caregiver burden may be unaffected by information exchange. Given the limitations of current communication methods, future work should explore directionality of the associations we found and identify visit communication strategies with caregivers that optimize caregiver and patient outcomes.

Opioid-Prescribing Approaches-One-Size-Fits-All versus Patient-Centric and Procedure-Focused-Among Podiatric Physicians: A Cross-Sectional Study.

BACKGROUND: More than half of opioid misusers last obtained opioids from a friend or relative, a problematic reflection of the commonly known opioid reservoir maintained by variable prescription rates and, notably, excessive postoperative prescription. We examined the postoperative opioid-prescribing approaches among podiatric physicians. METHODS: We administered a scenario-based, anonymous, online questionnaire via an online survey platform. The questionnaire consisted of five patient-foot surgery scenarios aimed at discerning opioid-prescribing approaches. Respondents were asked how many opioid "pills" (dosage units) that they would prescribe at the time of surgery. We divided respondents into two opioid-prescribing approach groups: one-size-fits-all (prescribed the same dosage units regardless of the scenario) and patient-centric and procedure-focused (prescribed varied amounts of opioid dosage units based on the patient's opioid history and the procedure provided in each scenario). We used the Mann-Whitney U test to determine the difference between the opioid dosage units prescribed at the time of surgery by the two groups. RESULTS: Approximately half of the respondents used a one-size-fits-all postoperative opioid-prescribing approach. Podiatric physicians who used a patient-centric and procedure-focused approach reported prescribing significantly fewer opioid dosage units in scenarios 1 (partial toe amputation; -9.1; P = .0087) and 2 (incision and drainage with partial fifth-ray resection; -12.3; P = .0024), which represented minor procedures with opioid-naive patients. CONCLUSIONS: Podiatric physicians who used a one-size-fits-all opioid-prescribing approach prescribed more postoperative opioid dosage units regardless of the scenario. Given that the patient population requiring foot surgery is diverse and may have multiple comorbidities, the management of postoperative pain, likewise, should be diverse and nuanced. The patient-centric and procedure-focused approach is suited to limit excess prescribing while defending the physician-patient relationship.

American Podiatric Surgeons' Postoperative Multimodal Analgesic-Prescribing Practice: A 2019-2020 National Survey.

BACKGROUND: Surgery is a common setting for opioid-naive patients to first be exposed to opioids. Understanding the multimodal analgesic-prescribing habits of podiatric surgeons in the United States may be helpful to refining prescribing protocols. The purpose of this benchmark study was to identify whether certain demographic characteristics of podiatric surgeons were associated with their postoperative multimodal analgesic-prescribing practices. METHODS: We administered a scenario-based, voluntary, anonymous, online questionnaire that consisted of patient scenarios with a unique podiatric surgery followed by a demographics section. We developed multiple logistic regression models to identify associations between prescriber characteristics and the odds of supplementing with a nonsteroidal anti-inflammatory drug, regional nerve block, and anticonvulsant agent for each scenario. We developed multiple linear regression models to identify the association of multimodal analgesic-prescribing habits and the opioid dosage units prescribed at the time of surgery. RESULTS: Eight hundred sixty podiatric surgeons completed the survey. Years in practice was a statistically significant variable in multiple scenarios. Compared with those in practice for more than 15 years, podiatric surgeons in practice 5 years or less had increased odds of reporting supplementation with an anticonvulsant agent in scenarios 1 (odds ratio [OR], 2.4; 95% confidence interval [CI], 1.11-5.18; P = .03), 3 (OR, 2.97; 95% CI, 1.55-5.68; P = .001), 4 (OR, 2.54; 95% CI, 1.56-4.12; P < .001), and 5 (OR, 2.07; 95% CI, 1.29-3.32; P = .003). CONCLUSIONS: Podiatric surgeons with fewer years in practice had increased odds of supplementing with an anticonvulsant. Approximately one-third of podiatric surgeons reported using some form of a nonopioid analgesic and an opioid in every scenario. The use of multimodal analgesics was associated with a reduction in the number of opioid dosage units prescribed at the time of surgery and may be a reasonable adjunct to current protocols.

Differences between patients in whom physicians agree versus disagree about the preoperative diagnosis of heart failure.

STUDY OBJECTIVE: To quantify preoperative heart failure (HF) diagnostic agreement and identify characteristics of patients in whom physicians agreed versus disagreed about the diagnosis. DESIGN: Observational cohort study. SETTING: Patients undergoing major non-cardiac surgery at an academic center between 2015 and 2019. PATIENTS: 40,659 patients undergoing major non-cardiac surgery, among which a stratified subsample of 1018 patients with and without documented HF was reviewed. INTERVENTIONS: Via a panel of physicians frequently managing patients with HF (cardiologists, cardiac anesthesiologists, intensivists), detailed chart reviews were performed (two per patient; median review time 32 min per reviewer per patient) to render adjudicated HF diagnoses. MEASUREMENTS: Adjudicated diagnostic agreement measures (percent agreement, Krippendorf's alpha) and univariate comparisons (standardized differences) between patients in whom physicians agreed versus disagreed about the preoperative HF diagnosis. MAIN RESULTS: Among patients with documented HF, physicians agreed about the diagnosis in 80.0% of cases (consensus positive), disagreed in 13.8% (disagreement), and refuted the diagnosis in 6.3% (consensus negative). Conversely, among patients without documented HF, physicians agreed about the diagnosis in 88.0% (consensus negative), disagreed in 8.4% (disagreement), and refuted the diagnosis in 3.6% (consensus positive). The estimated agreement for the 40,659 cases was 91.1% (95% CI 88.3%-93.9%); Krippendorff's alpha was 0.77 (0.75-0.80). Compared to patients in whom physicians agreed about a HF diagnosis, patients in whom physicians disagreed exhibited fewer guideline-defined HF diagnostic criteria. CONCLUSIONS: Physicians usually agree about HF diagnoses adjudicated via chart review, although disagreement is not uncommon and may be partly explained by heterogeneous clinical presentations. Our findings inform preoperative screening processes by identifying patients whose characteristics contribute to physician disagreement via chart review.

Family caregiver roles and challenges in assisting patients with cancer treatment decision-making: Analysis of data from a national survey.

BACKGROUND: We aimed to describe the roles and challenges of family caregivers involved in patients' cancer treatment decision-making. METHODS: Family caregiver-reported data were analyzed from a national survey conducted in the United States by CancerCare® (2/2021-7/2021). Four select-all-that-apply caregiver roles were explored: (1) observer (patient as primary decision-maker); (2) primary decision-maker; (3) shared decision-maker with patient and (4) decision delegated to healthcare team. Roles were compared across five treatment decisions: where to get treatment, the treatment plan, second opinions, beginning treatment and stopping treatment. Ten challenges faced by caregivers (e.g., information, cost, treatment understanding) were then examined. χ2 and regression analyses were used to assess associations between roles, decision areas, challenges and caregiver sociodemographics. RESULTS: Of 2703 caregiver respondents, 87.6% reported involvement in patient decisions about cancer treatment, including 1661 who responded to a subsection further detailing their roles and challenges with specific treatment decisions. Amongst these 1661 caregivers, 22.2% reported an observing role, 21.3% a primary decision-making role, 53.9% a shared decision-making role and 18.1% a role delegating decisions to the healthcare team. Most caregivers (60.4%) faced ≥1 challenge, the most frequent being not knowing how treatments would affect the patient's physical condition (24.8%) and quality of life (23.2%). In multivariable models, being Hispanic/Latino/a was the strongest predictor of facing at least one challenge (b = -0.581, Wald = 10.69, p < .01). CONCLUSIONS: Most caregivers were involved in patients' cancer treatment decisions. The major challenge was not understanding how treatments would impact patients' physical health and quality of life. Challenges may be more commonly faced by Hispanic/Latino/a caregivers. PATIENT OR PUBLIC CONTRIBUTION: The CancerCare® survey was developed in partnership with caregiving services and research experts to describe the role of cancer family caregivers in patient decision-making and assess their needs for support. All survey items were reviewed by a CancerCare advisory board that included five professional patient advocates and piloted by a CancerCare social worker and other staff who provide counselling to cancer caregivers.

Decision support training for advanced cancer family caregivers: Study protocol for the CASCADE factorial trial.

BACKGROUND: Patients with advanced cancer face numerous decisions when diagnosed and often receive decision support from family caregivers. The CASCADE (CAre Supporters Coached to be Adept DEcision partners) factorial trial intervention aims to train caregivers in skills to provide effective decision support to patients and identify most effective intervention components. METHODS: This is a 2-site, single-blind, 24 factorial trial to test components of the CASCADE decision support training intervention for family caregivers of patients with newly-diagnosed advanced cancer delivered by specially-trained, telehealth, palliative care lay coaches over 24 weeks. Family caregivers (target N = 352) are randomly assigned to one of 16 combinations of four components with two levels each: 1) psychoeducation on effective decision partnering principles (1 vs. 3 sessions); 2) decision support communication training (1 session vs. none); 3) Ottawa Decision Guide training (1 session vs. none) and 4) monthly follow-up (1 call vs. calls for 24 weeks). The primary outcome is patient-reported decisional conflict at 24 weeks. Secondary outcomes include patient distress, healthcare utilization, caregiver distress, and quality of life. Mediators and moderators (e.g., sociodemographics, decision self-efficacy, social support) will be explored between intervention components and outcomes. Results will be used to build two versions of CASCADE: one with only effective components (d ≥ 0.30) and another optimized for scalability and cost. DISCUSSION: This protocol describes the first factorial trial, informed by the multiphase optimization strategy, of a palliative care decision-support intervention for advanced cancer family caregivers and will address the field's need to identify effective components that support serious illness decision-making. TRIAL REGISTRATION: NCT04803604.

Short-Term Patient Outcomes after Placement of an Internal Joint Stabilizer for Terrible Triad Injuries: A Multicenter Study.

PURPOSE: The purpose of this study was to assess the functional and patient-reported outcomes after the use of the internal joint stabilizer (IJS) for unstable terrible triad injuries. Specifically, we sought to determine our complication rate and the impact of complications on patient outcomes. METHODS: We identified all patients who had an IJS placed as a supplemental fixation for a terrible triad injury at two urban, level 1 academic medical centers. We reviewed these patients' charts for demographic information, complication profiles, postoperative range of motion (ROM), and pain-level data. We also collected the QuickDASH and Patient-Rated Elbow Evaluation (PREE) scores. Descriptive statistics were reported. Final visit data were compared between patients who returned to the OR for a complication and those who did not. RESULTS: From 2018 to 2020, 29 patients had an IJS placed for a terrible triad injury. The median final follow-up was 6.3 months after surgery (IQR: 6.2 months). There were 38 complications in 19 patients (65.5%) that required 12 patients to return to the OR (41.3%) for procedures beyond simple IJS removal. There were no significant differences in the ROM between patients who returned to the OR for a complication and those who did not. QuickDASH and PREE scores were greater (indicating more disability) in patients who had a complication that required a secondary surgical procedure. CONCLUSIONS: Patients who receive an IJS incur a high rate of complications. When patients sustain complications that require secondary surgeries, their ultimate functional outcome scores worsen. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

Using a Contemporary Portable Metabolic Gas Exchange System for Assessing Energy Expenditure: A Validity and Reliability Study.

There are several methods available to assess energy expenditure, all associated with inherent pros and cons that must be adequately considered for use in specific environments and populations. A requirement of all methods is that they must be valid and reliable in their capability to accurately measure oxygen consumption (VO2) and carbon dioxide production (VCO2). The purpose of this study was to evaluate the reliability and validity of the mobile CO2/O2 Breath and Respiration Analyzer (COBRA) relative to a criterion system (Parvomedics TrueOne 2400®, PARVO) with additional measurements to compare the COBRA to a portable system (Vyaire Medical, Oxycon Mobile®, OXY). Fourteen volunteers with a mean of 24 years old, body weight of 76 kg, and a VO2peak of 3.8 L∙min-1 performed four repeated trials of progressive exercises. Simultaneous steady-state measurements of VO2, VCO2, and minute ventilation (VE) by the COBRA/PARVO and OXY systems were conducted at rest, while walking (23-36% VO2peak), jogging (49-67% VO2peak), and running (60-76% VO2peak). Data collection was randomized by the order of system tested (COBRA/PARVO and OXY) and was standardized to maintain work intensity (rest to run) progression across study trials and days (two trials/day over two days). Systematic bias was examined to assess the accuracy of the COBRA to PARVO and OXY to PARVO across work intensities. Intra- and inter-unit variability were assessed with interclass correlation coefficients (ICC) and a 95% limit of agreement intervals. The COBRA and PARVO produced similar measures for VO2 (Bias ± SD, 0.01 ± 0.13 L·min-1; 95% LoA, (-0.24, 0.27 L·min-1); R2 = 0.982), VCO2 (0.06 ± 0.13 L·min-1; (-0.19, 0.31 L·min-1); R2 = 0.982), VE (2.07 ± 2.76 L·min-1; (-3.35, 7.49 L·min-1); R2 = 0.991) across work intensities. There was a linear bias across both the COBRA and OXY with increased work intensity. The coefficient of variation for the COBRA ranged from 7 to 9% across measures for VO2, VCO2, and VE. COBRA was reliable across measurements for VO2 (ICC = 0.825; 0.951), VCO2 (ICC = 0.785; 0.876), and VE (ICC = 0.857; 0.945) for intra-unit reliability, respectively. The COBRA is an accurate and reliable mobile system for measuring gas exchange at rest and across a range of work intensities.

Can simulation-based education or other education interventions replace clinical placement in medical radiation sciences? A narrative review.

OBJECTIVES: In response to increasing student enrolment and workload pressures from the Covid-19 pandemic, a recent focus on health student preparation programs has been on curricula adaptations and replacement of clinical placement time with alternative education activities. The aim of the narrative review was to explore the current evidence relating to education activities in Medical Radiation Sciences (MRS) used to replace clinical placements or part of clinical placements. Medline, CINAHL and Web of Science databases were used to search for articles published between 2017 and 2022. Data from the literature was summarised into (1) planning and development of clinical replacement learning activities in MRS, (2) evaluation of clinical replacement activities, and (3) benefits and challenges of clinical replacement in MRS. KEY FINDINGS: Planning and development of clinical replacement learning activities in MRSrequires support from a wide range of stakeholders, and evidence from activities already implemented exists. Activities largely encompass an institution-specific focus. Developed clinical replacement activities use a blended approach, with simulation-based education (SBE) as a main teaching platform. Evaluation of clinical replacement activities are largely focused on students' achievement of learning objectives relating to practical and communication skills. Emerging evidence based on small student samples shows that clinical and clinical replacement activities provide similar results in terms of learning objectives. CONCLUSION: Benefits and challenges of clinical replacement in MRS are similar to those presented in the other health professions. The balance between quality and quantity of teaching and learning experiences for clinical skill development in MRS needs to be further investigated. IMPLICATIONS FOR PRACTICE: To meet the dynamic challenges of the health care environment and MRS profession, a major goal in the future will be to affirm the benefit of clinical replacement activities for MRS students.

Cognitive Bias in Postoperative Opioid-Prescribing Practice.

BACKGROUND: Given that excess opioid prescriptions contribute to the US opioid epidemic and there are few national opioid-prescribing guidelines for the management of acute pain, it is pertinent to determine whether prescribers can sufficiently assess their own prescribing practice. We investigated podiatric surgeons' ability to evaluate whether their own opioid-prescribing practice is less than, near, or above that of an "average" prescriber. METHODS: We administered a scenario-based, voluntary, anonymous, online questionnaire consisting of five surgery-based scenarios commonly performed by podiatric surgeons. Respondents were asked the quantity of opioids they would prescribe at the time of surgery. Respondents were also asked to rate their prescribing practice compared with the average (median) podiatric surgeon. We compared self-reported behavior to self-reported perception ("I prescribe less than average," "I prescribed about average," and "I prescribe more than average"). Analysis of variance was used for univariate analysis among the three groups. We used linear regression to adjust for confounders. Data restriction was used to account for restrictive state laws. RESULTS: One hundred fifteen podiatric surgeons completed the survey in April 2020. Less than half of the time, respondents accurately identified their own category. Consequently, there were no statistically significant differences among podiatric surgeons who reported that they "prescribe less," "prescribe about average," and "prescribe more." Paradoxically, there was a flip in scenario 5: respondents who reported they "prescribe more" actually prescribed the least and respondents who believed they "prescribe less" actually prescribed the most. CONCLUSIONS: Cognitive bias, in the form of a novel effect, occurs in postoperative opioid-prescribing practice; in the absence of procedure-specific guidelines or an objective standard, podiatric surgeons, more often than not, were unaware of how their own opioid-prescribing practice measured up to that of other podiatric surgeons.

Clinical Outcomes of Surgical Repair for Partial Distal Biceps Tendon Tears.

PURPOSE: The purpose of this study was to describe the outcomes of patients treated with surgical repair of partial tears of the distal biceps tendon. METHODS: The study was a retrospective review of repairs of partial tears of the distal biceps tendon performed by multiple surgeons from January 1, 2015 to October 15, 2020. Inclusion criteria consisted of preoperative magnetic resonance imaging indicative of distal biceps pathology without a complete tear and surgical treatment with intraoperative confirmation of a partial tear. The presence of preceding trauma, duration of symptoms, and postoperative complications were documented. Patients were contacted for outcome assessment using the Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH) and Patient-Reported Elbow Evaluation outcome measures. Clinical outcomes were obtained from 56 of 74 (76%) eligible patients with an average follow-up of 46 months (range: 15-85 months). RESULTS: After surgery, the median QuickDASH was 2.3 (interquartile range, 0-9.7), and the median Patient-Reported Elbow Evaluation score was 1 (interquartile range, 0-12). Postoperative QuickDASH scores were significantly lower than the preoperative scores. Known traumas preceding the symptoms and duration of symptoms before surgery were not significantly associated with the outcome. Of all eligible patients, 30 complications were reported in 25 (34%) patients and included 2 reruptures, 2 cases of heterotopic ossification, 1 deep infection, 1 case of implant irritation, 21 neuropraxias, and 3 hematomas. Five (7%) patients underwent 6 reoperations including 1 revision for a rerupture, 1 irrigation and debridement, 2 heterotopic ossification excisions, 1 hematoma evacuation, and 1 implant removal. CONCLUSIONS: The results suggest that the repair of partial distal biceps tendon tears is a viable treatment option with significant improvement in QuickDASH. There was no significant relationship between the postoperative outcome and duration of symptoms or known traumas preceding the symptoms. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

Biomechanical Evaluation of 2 Common Approaches for Total Elbow Arthroplasty: Triceps Tongue Compared With Triceps Reflecting.

PURPOSE: We hypothesize that the triceps tongue approach will be equivalent in strength to the triceps reflecting approach in load to failure following a cyclic preload. METHODS: Seven paired fresh-frozen cadaveric arms were dissected using the triceps reflecting approach or triceps tongue approach to the posterior elbow. The triceps was then repaired in each specimen, and the elbows were placed in a testing jig. Elbows were preloaded in a cyclic fashion at 5 lbs (2.3 kgf) for 200 cycles in flexion/extension, followed by load to failure. The stiffness and ultimate failure strength for each specimen were determined. We defined ultimate failure as gapping in the suture construct of 4 mm or suture breakage. RESULTS: One of the triceps tongue specimens was excluded due to a testing error, resulting in 6 elbows in this group. There were no tendon repair failures during the cyclic preload. The median ultimate failure of the reflecting group occurred at 65 pounds, compared to 115 pounds in the tongue group. This was significantly different. The reflecting approach consistently failed along the entire bone-tendon interface. The tongue approach failed at the proximal repair site in 4 of 6 specimens, while the longitudinal aspect of the tendon repair remained intact. CONCLUSIONS: Following a cyclic preload of 5 lbs for 200 cycles, the triceps tongue repair is stronger than triceps reflecting in ultimate failure. The mode of failure of triceps tongue repair may be superior to that of triceps reflecting. CLINICAL RELEVANCE: This study may help guide surgeons when choosing a "triceps off" approach to total elbow arthroplasty.

Patient Portal Use Among Family Caregivers of Individuals With Dementia and Cancer: Regression Analysis From the National Study of Caregiving.

Background: Family caregivers are often inexperienced and require information from clinic visits to effectively provide care for patients. Despite reported deficiencies, 68% of health systems facilitate sharing information with family caregivers through the patient portal. The patient portal is especially critical in the context of serious illnesses, like advanced cancer and dementia, where caregiving is intense and informational needs change over the trajectory of disease progression. Objective: The objective of our study was to analyze a large, nationally representative sample of family caregivers from the National Study of Caregiving (NSOC) to determine individual characteristics and demographic factors associated with patient portal use among family caregivers of persons living with dementia and those living with cancer. Methods: We conducted a secondary data analysis using data from the 2020 NSOC sample of family caregivers linked to National Health and Aging Trends Study. Weighted regression analysis by condition (ie, dementia or cancer) was used to examine associations between family caregiver use of the patient portal and demographic variables, including age, race or ethnicity, gender, employment status, caregiver health, education, and religiosity. Results: A total of 462 participants (representing 4,589,844 weighted responses) were included in our analysis. In the fully adjusted regression model for caregivers of persons living with dementia, Hispanic ethnicity was associated with higher odds of patient portal use (OR: 2.81, 95% CI 1.05-7.57; P=.04), whereas qualification lower than a college degree was associated with lower odds of patient portal use by family caregiver (OR 0.36, 95% CI 0.18-0.71; P<.001. In the fully adjusted regression model for caregivers of persons living with cancer, no variables were found to be statistically significantly associated with patient portal use at the .05 level. Conclusions: In our analysis of NSOC survey data, we found differences between how dementia and cancer caregivers access the patient portal. As the patient portal is a common method of connecting caregivers with information from clinic visits, future research should focus on understanding how the portal is used by the groups we have identified, and why.

Deriving International Classification of Diseases, 9th and 10th revision, codes for identifying and following up patients with diabetic lower extremity ulcers.

Objective: Administrative claims data offer a rich data source for clinical research. However, its application to the study of diabetic lower extremity ulceration is lacking. Our objective was to create a widely applicable framework by which investigators might derive and refine the International Classification of Diseases, 9th and 10th revision (ICD-9 and ICD-10, respectively) codes for use in identifying diabetic, lower extremity ulceration. Methods: We created a seven-step process to derive and refine the ICD-9 and ICD-10 coding lists to identify diabetic lower extremity ulcers. This process begins by defining the research question and the initial identification of a list of ICD-9 and ICD-10 codes to define the exposures or outcomes of interest. These codes are then applied to claims data, and the rates of clinical events are examined for consistency with prior research and changes across the ICD-9 to ICD-10 transition. The ICD-9 and ICD-10 codes are then cross referenced with each other to further refine the lists. Results: Using this method, we started with 8 ICD-9 and 43 ICD-10 codes used to identify lower extremity ulcers in patients with known diabetes and peripheral arterial disease and examined the association of ulceration with lower extremity amputation. After refinement, we had 45 ICD-9 codes and 304 ICD-10 codes. We then grouped the codes into eight clinical exposure groups and examined the rates of amputation as a rudimentary test of validity. We found that the rate of lower extremity amputation correlated with the severity of lower extremity ulceration. Conclusions: We identified 45 ICD-9 and 304 ICD-10 ulcer codes, which identified patients at risk of amputation from diabetes and peripheral artery disease. Although further validation at the medical record level is required, these codes can be used for claims-based risk stratification for long-term outcomes assessment in the treatment of patients at risk of limb loss.

Primary Repair of Chronic Distal Biceps Tendon Tears.

BACKGROUND: This study reports the clinical results following primary repair of distal biceps tendon ruptures more 6 weeks after injury. METHODS: A retrospective review of distal biceps tendon repairs performed by 8 different hand surgeons from January 1, 2015 to October 15, 2020 was performed. Patients with complete tears surgically treated ≥6 weeks after injury without tendon graft were included. Thirty patients qualified and underwent chart review for complication and range of motion (ROM) data. They were contacted for final patient-reported outcome measures (PROMs) using Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH) and Patient Reported Elbow Evaluation (PREE) scores. Final PROMs were obtained from 21 patients with an average follow-up of 31.3 months (range: 4-71 months). RESULTS: Average time from injury to repair was 71 days (range: 42-204). The average QuickDASH score was 6.6 (±6.2) and PREE score was 7.8 (±8.0). The amount of elbow flexion necessary to complete the repair was documented in 21 patients and averaged 64º (±10º). Postoperatively, patients achieved an average extension/flexion of 1º (±1º) to 138º (±2º) and pronation/supination of 76º (±4º) to 77º (±3º). Complications were reported in 14 patients (47%) and included 2 re-ruptures, 1 adhesive scar formation, 1 superficial infection, 1 intraoperative lateral antebrachial cutaneous nerve laceration, 12 neuropraxias, and 1 case of heterotopic ossification (HO). CONCLUSIONS: Primary repair of chronic distal biceps tendon tears greater than 6 weeks from injury demonstrated excellent PROMs and elbow ROM. However, the complication rate may be higher than early repair.

Discovery of AZD8154, a Dual PI3Kγδ Inhibitor for the Treatment of Asthma.

Starting from our previously described PI3Kγ inhibitors, we describe the exploration of structure-activity relationships that led to the discovery of highly potent dual PI3Kγδ inhibitors. We explored changes in two positions of the molecules, including macrocyclization, but ultimately identified a simpler series with the desired potency profile that had suitable physicochemical properties for inhalation. We were able to demonstrate efficacy in a rat ovalbumin challenge model of allergic asthma and in cells derived from asthmatic patients. The optimized compound, AZD8154, has a long duration of action in the lung and low systemic exposure coupled with high selectivity against off-targets.

Digital mammographic interpretation by UK radiographer mammographers: A JAFROC analysis of observer performance.

INTRODUCTION: Radiologists utilise mammography test sets to bench mark their performance against recognised standards. Using a validated test set, this study compares the performance of radiographer readers against previous test results for radiologists. METHODS: Under similar test conditions radiographer readers were given an established test set of 60 mammograms and tasked to identify breast cancer, they were measured against their ability to identify, locate and give a confidence level for cancer being present on a standard set of mammographic images. The results were then compared to previously published results for radiologists for similar or the same test sets. RESULTS: The 10 radiographer readers demonstrated similar results to radiologists and for lesion sensitivity were the highest scoring group. The study group score a sensitivity of 83; a specificity of 69.3 and lesion sensitivity of 74.8 with ROC and JAFROC scores of 0.86 and 0.74 respectively. CONCLUSION: Under test conditions radiographers are able to identify and accurately locate breast cancer in a range of complex mammographic backgrounds. IMPLICATIONS FOR PRACTICE: The study was performed under experimental conditions with results comparable to breast radiologists under similar conditions, translation of these findings into clinical practice will help address access and capacity issues in the timely identification and diagnosis of breast cancer.
