RESUMO

INTRODUCTION AND HYPOTHESIS: Surgeon kinematics play a significant role in the prevention of patient injury. We hypothesized that elbow extension and ulnar wrist deviation are associated with bladder injury during simulated midurethral sling (MUS) procedures. METHODS: We used motion capture technology to measure surgeons' flexion/extension, abduction/adduction, and internal/external rotation angular time series for shoulder, elbow, and wrist joints. Starting and ending angles, minimum and maximum angles, and range of motion (ROM) were extracted from each time series. We created anatomical multibody models and applied linear mixed modeling to compare kinematics between trials with versus without bladder penetration and attending versus resident surgeons. A total of 32 trials would provide 90% power to detect a difference. RESULTS: Out of 85 passes, 62 were posterior to the suprapubic bone and 20 penetrated the bladder. Trials with versus without bladder penetration were associated with more initial wrist dorsiflexion (-27.32 vs -9.03°, p = 0.01), less final elbow flexion (39.49 vs 60.81, p = 0.03), and greater ROM in both the wrist (27.48 vs 14.01, p = 0.02), and elbow (20.45 vs 12.87, p = 0.04). Wrist deviation and arm pronation were not associated with bladder penetration. Compared with attendings, residents had more ROM in elbow flexion (14.61 vs 8.35°, p < 0.01), but less ROM in wrist dorsiflexion (13.31 vs 20.33, p = 0.02) and arm pronation (4.75 vs 38.46, p < 0.01). CONCLUSIONS: Bladder penetration during MUS is associated with wrist dorsiflexion and elbow flexion but not internal wrist deviation and arm supination. Attending surgeons exerted control with the wrist and forearm, surgical trainees with the elbow. Our findings have direct implications for MUS teaching.

RESUMO

BACKGROUND: Rotator cuff tears are a prevalent cause of shoulder pain and dysfunction. For those who fail initial conservative treatment, operative intervention can be pursued. A significant and common complication after rotator cuff repair (RCR) is retearing or nonhealing. Numerous augmentations to traditional suture RCR have been studied. Of these, the Smith + Nephew Regeneten bioinductive collagen patch has had promising initial results; however, analytic data for its use are lacking, and there is no meta-analysis comparing the available data to historical RCR outcomes. METHODS: A PRISMA-guided literature search was conducted using Ovid MEDLINE, PubMED, Cochrane, and ClinicalTrials.gov. Thirteen studies met inclusion and exclusion criteria. Only clinical trials on full and partial-thickness tears were included. American Shoulder and Elbow Surgeon score, Constant-Murley Score, the visual analog scale for pain, the minimal clinically important difference (MCID), tendon thickness, and complication rates were primary outcomes of interest. A meta-analysis was performed to determine the overall complication and retear rate from the included studies. RESULTS: American Shoulder and Elbow Surgeon score, Constant-Murley Score, and visual analog scale for pain improved significantly in all studies that reported them, and most patients achieved MCID. Patient-reported outcome measure improvements were similar to historical improvements in standard RCR, and a similar proportion of patients achieved MCID after standard repair. Tendon thickness improved significantly and to a similar degree as standard RCR. Overall retear rate after full thickness RCR augmented with the bioinductive patch was 8.3%. For partial thickness RCR, total retear rate was of 1.1% across all patients. The overall complication rate with the bioinductive patch was 15.5% across all full-thickness RCR studies and 16.2% in partial thickness RCR. We found overall retear rate to be lower after augmentation with the bioinductive patch compared to traditional repair; however, the overall complication rate was similar for full-thickness tears and higher for partial-thickness tears. Lastly, adverse reactions to the bioinductive patch were noted at 0.2%. CONCLUSIONS: The bioinductive collagen patch appears to be a safe augmentation for rotator cuff repair. Patients are likely to experience significant subjective improvement in patient-reported outcome measures and significant increases in tendon thickness. Retear rate has been a concern after RCR for decades, and the bioinductive patch may help mitigate this risk. There is lack of case-control studies comparing the bioinductive patch to traditional suture RCR. Such data are needed to better determine the role of the bioinductive patch in the treatment of full and partial-thickness rotator cuff repairs.

RESUMO

OBJECTIVE: This study aimed to determine the feasibility of using a wrist-based fitness tracking device to assess sleep among Obstetrics and Gynecology (OBGYN) trainees who engaged in a yoga-based wellness program. We also sought to evaluate the effects of yoga on sleep. STUDY DESIGN: A quality improvement initiative consisting of an 8-week wellness program of weekly yoga classes, nutrition, and physical challenges was implemented for OBGYN residents and Maternal-Fetal Medicine fellows. The Polar A370 fitness tracker device was provided and synced to the Polar Flow for Coach program for inclusion. Data obtained included total and restful sleep from each night the device were worn. Pre- and post-assessment of the Pittsburg Sleep Quality Index (PSQI) were compared. Linear mixed models were used to estimate and test the effect of yoga on sleep while controlling for on-call shifts. RESULTS: Of the 15 participants who synced their device, 13 (87%) were included for analysis. Sleep data from 572 nights were analyzed. The mean (SD) total sleep was 434.28 (110.03) minutes over the 8 weeks. A minimum of 7 hours (420 minutes) of total sleep occurred 59.3% of the time. After controlling for Friday or Saturday night on-call, those who attended yoga class had a significantly greater total sleep (yoga: 425.14 minutes [41.89], no yoga: 357.33 [43.04] minutes; p = 0.04). There was no significant change in the mean global PSQI score after the program (pre: 5.0 [1.6], post: 5.1 [2.5], p = 0.35). CONCLUSION: Wearable fitness monitors provide insight into sleep patterns displayed during training and can serve as a tool to identify those who are sleep deprived and assist in the evaluation of trainee wellness. Training programs are encouraged to provide access to yoga and mindfulness interventions to improve sleep and possibly clinical performance. KEY POINTS: · Yoga improves trainee sleep by approximately 60 minutes.. · Total and restful sleep are reduced during night float rotation.. · Trainees obtained 7 hours of sleep approximately 60% of the time..

RESUMO

BACKGROUND: The treatment of partially displaced radial head fractures is determined not only by the type of fracture but also by patient characteristics such as age, occupation, hand dominance, mechanism of injury, and concomitant injuries and comorbidities. The goal of this study was to employ the Delphi method to achieve consensus on the management of patients with radial head fractures, utilizing the experience of the ASES Elbow Fracture-Dislocation Multicenter Study Group and Mayo Elbow Club surgeons. METHODS: The initial survey was sent to participants, which included consent to participate in the study and questions about their experience, knowledge, and interest in participating in the Delphi method. We used both open-ended and category-based questions. The second questionnaire generated 76 variables, and individual questions with mean Likert ratings of <2.0 or >4.0 were deemed significant and merged to form multifactorial clinical scenarios relating to both nonoperative and operative management, respectively. RESULTS: Of the surgeons who responded to the questionnaire, 64% were from the United States, while the remainder were from overseas practices. Years in practice on average were 12.4 years (range, 1-40). Seven of the 76 factors met the criteria of a mean Likert score of <2.0 or >4.0. These factors were as follows: age, block to the range of motion (ROM) after aspiration/injection, crepitation with ROM, tenderness over the distal radioulnar joint and/or interosseous membrane (dorsal forearm), gap and/or displacement >2 mm on imaging, complete loss of contact of the head with the rest of the radius on imaging, and fracture head involvement 30% on imaging. Twenty-two (46%) of the 96 clinical scenarios gained >90% consensus in favor of surgical treatment, whereas 8 (17%) reached >90% consensus in favor of nonoperative treatment. CONCLUSION: Obtaining expert consensus on the treatment of radial head fractures remains challenging. Certain factors such as gap/displacement ≥2 mm without complete loss of contact, ≥30% head involvement with a block to an ROM regardless of tenderness over distal radioulnar joint or interosseous membrane (dorsal forearm), or crepitation when the patient was <80 years of age led to a recommendation of operative treatment in 100% of the surveyed surgeons. Patients older than 80 years with no block to ROM after aspiration/injection, no crepitation with ROM, and no tenderness on distal radioulnar joint/interosseous membrane (dorsal forearm) were recommended for nonoperative treatment regardless of the size of the radial head involvement on imaging.

RESUMO

BACKGROUND: Orthopaedic devices comprise nearly 20% of devices on the market and 12% to 20% of these devices undergo a recall within 10 years. More than 95% of these devices are approved without supporting clinical data through the Food and Drug Administration's 510(k) pathway. The risk of recall of orthopaedic arthroplasty devices approved through the 510(k) pathway has not been previously studied. METHODS: The FDA 510(k) database was queried for orthopaedic devices approved between January 01, 2008 and December 31, 2018 and subsequently codified to hip and knee arthroplasty devices using product codes. The database included 904 arthroplasty devices during the study period, with hip and knee making up 53.7% (485) and 46.3% (419) of devices, respectively. Information regarding numbers, dates, and reasons for recall were recorded. Cumulative incidence function was conducted to compare the risk of recall between hip and knee arthroplasty. RESULTS: In total, 94 (19.4%) hip and 85 (20.3%) knee devices were recalled. The hazard of recall by 10 years for hip and knee arthroplasty devices was approximately 24%, with no statistical differences between each region. The most common causes of recall were process control and device design, accounting for 29.6% and 26.3% of recalls, respectively, with no significant difference between study groups. CONCLUSION: The risk of recall for arthroplasty devices is more than that previously understood. Improved postmarket surveillance strategies along with increased physician participation in detecting and reporting device safety issues are necessary to strengthen patient safety.

RESUMO

BACKGROUND: COVID-19 disrupted health systems across the country. Pre-pandemic, patients accessing our urban safety-net hospital presented with three-fold higher rates of late-stage breast cancer than other Commission-on-Cancer sites. We sought to determine the effect of the COVID-19 pandemic on stage of breast cancer presentation and time to first treatment at our urban safety-net hospital. METHODS: An Institutional Review Board-approved cohort study of newly diagnosed breast cancer patients was conducted at our safety-net hospital comparing a COVID cohort (March 2020-February 2021, n = 82) with a pre-COVID cohort (March 2018-February 2019, n = 90). Demographic information, stage at presentation, and time to first treatment-subdivided into time from symptom to diagnosis and diagnosis to treatment-were collected and analyzed for effect of COVID pandemic. RESULTS: Cohorts were similar in age, race, and payor. More patients had late-stage disease during COVID (32%) than pre-COVID (19%, p = 0.05). There was a significantly longer time to first treatment during COVID (p = 0.0001) explained by a significantly longer time from symptom to diagnosis (p = 0.0001), with no difference in time from diagnosis to treatment. CONCLUSION: It was significantly more likely for patients to present to our safety-net hospital with late-stage breast cancer during COVID than pre-COVID. There was longer time to first treatment during COVID, driven by the increased time from symptom to diagnosis. Patients may have perceived that care was inaccessible during the pandemic or had competing priorities, driving delays. Efforts should be made to minimize disruption to safety-net hospitals during future shut-downs as these are among the most vulnerable patients.

RESUMO

BACKGROUND: The low mammography rates at the authors' safety-net hospital (SNH) are associated with higher rates of late-stage disease. Previously, they showed that a phone call-based intervention with reminder and scheduling components significantly increased mammography uptake by 12% in their population, but implementation was resource-heavy. This study analyzed whether a text-based intervention with reminder and scheduling components could increase mammography uptake at 3 months compared with usual care. METHODS: This randomized controlled study analyzed 1277 women ages 50 to 65 years who were overdue for a mammogram but had established care at a primary-care clinic within an urban SNH. The patients received intervention 1 (a text reminder with specific scheduling options), intervention 2 (a text reminder with open-ended scheduling options), or usual care (control). Differences in the percentage of mammography uptake at 3 months were compared between the intervention and control groups using a two-tailed chi-square test. RESULTS: The patients receiving a text-based reminder and scheduling opportunity were significantly more likely to receive mammograms within 3 months than those in the usual-care control group (10.2% vs 6.2%; χ2 = 5.6279; p = 0.03). In the intervention group, 10.3% of the participants scheduled an appointment for a mammogram via text, and 63% of these participants received a mammogram. Finally, mammography compliance did not differ by the type of scheduling offered (specific vs general) or by primary care clinic. CONCLUSIONS: Leveraging technology for reminders and scheduling via two-way text messaging is effective in increasing mammography uptake in an urban safety-net setting and may be used as part of a multi-tiered intervention to increase breast cancer screening in a safety-net setting.

RESUMO

INTRODUCTION: In treating lower urinary tract symptoms (LUTS), the risk of overtreatment with antibiotics must be reconciled with the risk of an untreated urinary tract infection (UTI) progressing to acute pyelonephritis (APN). Using Cerner HealthFacts, a longitudinal clinical informatics database, we aimed to determine risk factors associated with the development of APN from UTI in an effort to guide the initiation of empiric antibiotics. METHODS: We queried the Cerner HealthFacts database for women over age 18 with a positive urine culture. Any patient with an International Classification of Disease (ICD) code indicating chronic pyelonephritis was excluded. Development of APN within 30 days of the positive culture, specified by ICD coding, was our primary outcome. Patient and facility factors were assessed as potential risk factors for the development of APN using multivariable regression. RESULTS: Out of 58 344 women with a positive urine culture, 3.9% (2296) developed APN. Mean patient age was 54.4 ± 25.3 years. Overall, 12 variables were predictive for APN and 11 variables were protective against APN. Presence of obstructive and reflux uropathies (OR 4.58), presentation to an acute care facility (OR 3.19), urinary retention (OR 2.30), history of UTI (OR 2.19), and renal comorbidities (OR 2.07) conferred the highest odds of APN development. The most protective variable against APN development was cognitive impairment (OR 0.49). CONCLUSIONS: Identified risk factors associated with APN development may aid decisions regarding empiric antibiotic initiation for patients presenting with LUTS while awaiting urine culture results. The relationship between cognitive impairment and progression to APN deserves further study.

RESUMO

BACKGROUND: Psychological distress is common in patients with cancer. Distress can affect patients' engagement with treatment. We examined the relationship between psychological distress and treatment timeliness in a sample of adult oncology patients at a safety-net hospital. METHODS: A retrospective review was conducted of all patients screened for distress at a first outpatient oncology visit between March 1, 2014, and December 31, 2015 (n=500). The analytic sample (n=96) included patients with a new cancer diagnosis and a curative-intent treatment plan for lymphoma (stage I-IV), solid tumor malignancy (stage I-III), or head and neck cancer (stage I-IVb). Distress was measured using the Hospital Anxiety and Depression Scale. Using Poisson regression, we determined the effects of depression and anxiety on treatment timeliness. Patient age, sex, race/ethnicity, insurance type, cancer site, and cancer stage were included as covariates. RESULTS: Mean patient age was 54 years. The median treatment initiation interval was 28 days. Clinically significant anxiety was present in 34% of the sample, and clinically significant depression in 15%. Greater symptom severity in both anxiety and depression were associated with a longer treatment initiation interval after controlling for demographics and disease factors. The average days to treatment (DTT) was 4 days longer for patients with elevated anxiety scores and for those with elevated depression scores compared with those without. Overall survival was not associated with anxiety, depression, or DTT. CONCLUSIONS: In this safety-net patient sample, greater psychological distress was associated with slower time to treatment. As of writing, this is a new finding in the literature, and as such, replication studies utilizing diverse samples and distress measurement tools are needed.

RESUMO

BACKGROUND: The glycated hemoglobin (A1c) test is not recommended for sickle cell disease (SCD) patients. We examine ordering patterns of diabetes-related tests for SCD patients to explore misutilization of tests among this underserved population. METHODS: We used de-identified electronic health record (EHR) data in the Cerner Health Facts™ (HF) data warehouse to evaluate the frequency of A1c and fructosamine tests during 2010 to 2016, for 37,151 SCD patients from 393 healthcare facilities across the United States. After excluding facilities with no A1c data, we defined three groups of facilities based on the prevalence of SCD patients with A1c test(s): adherent facilities (no SCD patients with A1c test(s)), minor non-adherent facilities, major non-adherent facilities. RESULTS: We determined that 11% of SCD patients (3927 patients) treated at 393 facilities in the US received orders for at least one A1c test. Of the 3927 SCD patients with an A1c test, only 89 patients (2.3%) received an order for a fructosamine test. At the minor non-adherent facilities, 5% of the SCD patients received an A1c test while 58% of the SCD patients at the least adherent facilities had at least one A1c test. Overall, the percent of A1c tests ordered for SCD patients between 2010 and 2016 remained similar. CONCLUSIONS: Inappropriate A1c test orders among a sickle cell population is a significant quality gap. Interventions to advance adoption of professional recommendations that advocate for alternate tests, such as fructosamine, can guide clinicians in test selection to reduce this quality gap are discussed. The informatics strategy used in this work can inform other largescale analyses of lab test utilization using de-identified EHR data.

RESUMO

The SystemCHANGE™ intervention has led to great improvements in medication adherence, which is a challenge for nearly one-third of kidney transplant recipients. This secondary data analysis sought to measure the frequency of individual solutions utilized by participants in a previously conducted randomized controlled trial of the SystemCHANGE™ intervention and to determine which classes of solutions had greatest impact on improved medication adherence. Solutions that were significant predictors of improving medication adherence to the 85% or higher level included alarm cues (p ≤ 0.0001), time cues (p = 0.006), restructuring the physical environment (p = 0.048), and social support (p = 0.023). Alarm and time cues, restructuring the environment, and social support were successful solutions largely influenced by personal routine and environment consideration that might be prioritized in future studies when implementing SystemCHANGE™.

RESUMO

BACKGROUND: Our urban safety-net hospital (SNH) has very low screening mammogram rates within its primary care clinics. Despite Commission on Cancer (CoC) accreditation, we see ~ 3 × more late-stage breast cancer diagnoses than other CoC sites across the country, and recently showed this to be strongly associated with lack of screening (Ahmadiyeh et al. in J Health Care Poor Underserved, in press, 2020). Here we study whether a two-step intervention (phone calls and assistance scheduling mammograms) increases uptake over usual care. PATIENTS AND METHODS: Randomized controlled study of 890 women aged 50-65 years who were due for biennial screening mammograms and who were established within one of five primary care clinics at an urban SNH. Each patient in the intervention group was called with overdue status (up to three times, voicemail left if needed) and offered assistance scheduling mammogram appointment. Mammography uptake at 3 and 6 months was analyzed. RESULTS: Intervention significantly increased uptake compared with usual care at both timepoints (18% versus 6% at 3 months; χ2 = 27.597, p < 0.0001; 23% versus 12% at 6 months; χ2 = 18.0, p < 0.0001), with scheduling component driving effectiveness. Of those who were successfully contacted, uptake was significantly greater among those who scheduled appointments versus those who did not (47% versus 9%, χ2 = 95, p < 0.0001), and uptake was no different between contacted but not scheduled patients and usual care controls. CONCLUSIONS: Phone call with access-enhancing intervention (facilitating mammogram appointments) increased screening mammogram uptake among primary care patients in an urban safety-net setting and may be applicable to other urban SNHs around the country.

RESUMO

Single-spin methods of preparation of platelet-rich plasma are used widely in private practice, yet they have not been extensively studied and compared. The use of platelet-rich plasma (PRP) by the private practitioner can be facilitated by efficient and predictable PRP preparation. The primary purpose of this study was to study common methods of single-spin PRP preparation to determine their efficiency and variability. Six single-spin methods of PRP production from whole blood were analyzed. The primary measures were mean yield and standard deviation as the quotient of total platelet count in PRP produced divided by total platelet count in whole blood utilized. Each sample was analyzed in triplicate and the results were averaged. Secondary measures included red blood cell count (RBC) and white blood cell count (WBC), concentration ratio, and variable cost per million platelets produced. Sixty-four volunteers provided samples from 30 June 2017 to 30 September 2018. Seventeen to twenty six samples were utilized to assess each method. Yields for the six preparation methods (PMs) varied from 53(±18)% to 72(±13)%. Differences were observed for WBC count (1.8 to 14), Hematocrit (0.8 to 32), platelet concentration (568 to 1062), and variable cost per billion platelets produced ($1.55 to $44.31). All six methods evaluated provided a platelet yield of more than 50%, although two methods were less efficient than the others. Two methods were able to produce leukocyte-poor PRP. Variability was moderate across all methods, suggesting that estimation of platelet yield should be feasible from a baseline platelet count for all methods.

RESUMO

PURPOSE: Young breast cancer survivors (YBCS) face unique challenges in coping with disease, distress, and relationship concerns. The purposes of this study were to understand the acceptability and feasibility of an online Mindfulness-Based Intervention (MBI) for YBCS and their partners (i.e., Couples Mindfulness-Based Intervention: C-MBI) and to compare the effectiveness of the C-MBI to a closely-matched control, an online MBI for individuals (I-MBI). METHODS: YBCS and their partners were recruited. Couples were randomly assigned to an 8-week C-MBI (couples = 41) or to I-MBI (couples = 36), which included one-hour video modules, a manual, and guided-meditation audios. Both couple members participated in the C-MBI; only the YBCS participated in the control I-MBI. Participants answered surveys about individual- and couple-level functioning at baseline and post-intervention. RESULTS: Online delivery was shown to be feasible and acceptable. For YBCS and their partners, levels of perceived stress, anxiety, depression, and fatigue were lower after the intervention, in both conditions. Unexpectedly, however, participating in the C-MBI appeared to have detrimental effects on dyadic adjustment and relationship quality. CONCLUSION: Although YBCS and their partners reported online delivery was acceptable and benefited well-being, for couple-based MBIs to have benefits for relationship functioning, it may be necessary for couples to have the support of other couples and an instructor. Online delivery may be particularly acceptable and effective for clinical populations, including YBCS. Medical professionals may be more likely to recommend online-MBI programs to cancer survivors, because the programs are of little or no cost.

RESUMO

BACKGROUND: Optimal treatment of pancreatic ductal adenocarcinoma of the neck, body and tail (PDAC-NBT) necessitates R0 surgical resection. Preoperative radiographic identification of patients likely to achieve successful oncologic resection remains difficult. This study seeks to identify preoperative imaging characteristics predictive of non-R0 resections or impaired survival for PDAC-NBT. METHODS: Patients at five high-volume centers who underwent resection for PDAC-NBT were retrospectively analyzed. The most immediate preoperative cross-sectional scan was assessed along with outcome measures of overall survival and margin status. RESULTS: 330 patients were treated between 2001 and 2016. Margin status included 247 R0 (78.2%), 67 R1 (21.2%), and 2 R2 (0.6%). A non-R0 resection predicted worse survival (p = 0.0002). On preoperative imaging, patients with tumors greater than 20 mm, tumor attenuation greater than 70 Hounsfield units, or who demonstrated pancreatic atrophy and/or calcifications also had worse survival (p = 0.010, p = 0.036, p = 0.025 respectively). Patients with tumors interfacing with the splenic artery or vein or extending posteriorly achieved fewer R0 resections (p = 0.0006, p = 0.0004, p = 0.001, respectively). CONCLUSION: Preoperative cross-sectional imaging can identify tumor characteristics associated with poor survival and non-R0 resection. Further investigation is needed to identify the appropriate surgical and treatment modifications necessary to clinically benefit this subset of patients.

RESUMO

PURPOSE: About 80% of children with autism spectrum disorder (ASD) have sleep problems that may disrupt optimal family functioning. We explored the impact of sleep problems on families' resilience. DESIGN AND METHODS: An explanatory sequential mixed methods design was used to discern whether resilience differed between families whose children with ASD have or do not have sleep problems, to seek predictors for family hardiness/resilience, and to determine whether narrative findings support, expand, or conflict quantitative findings. RESULTS: Seventy complete surveys were returned from parents of children with ASD to compare sleep and family functioning. Fifty-seven children had sleep problems and six interviews regarding eight of these children were conducted. Parents of children with ASD and sleep problems had lower levels of resilience than those who slept well. Predictors of hardiness were social support, coping-coherence (stress management), and lower strain scores. Qualitative content analysis revealed a journey analogy with themes: finding the trailhead, dual pathways, crossing paths and choosing travel companions, forging new paths, resting along the way, and seeing the vistas. CONCLUSIONS: Qualitative findings supported quantitative findings regarding the impact of sleep problems but also expanded them by illustrating how families' resilience and children's socialization improved over time. Social support predicted family hardiness. Parents revealed that sleep issues contributed to family strains and described their progression to resilience and embracing their child. PRACTICE IMPLICATIONS: Findings support the need for community and provider advocacy and implicates a need for development of sleep interventions on behalf of families and children with ASD.
