ABSTRACT
OBJECTIVES: The Veterans Administration (VA) Mobility Screening and Solutions Tool (VA MSST) was developed to screen a patient's safe mobility level 'in the moment' and provide clinical decision support related to the use of safe patient handling and mobility (SPHM) equipment. This evidence-based flowchart tool is a common language tool that enables any healthcare worker at any time to accurately measure and communicate patient mobility and transfer equipment needs across disciplines and settings. METHODS: The VA MSST has four levels and differentiates between the need for powered and non-powered equipment depending on the patient's independence. Subject matter experts wrote scenarios for interrater reliability and validity testing. The initial VA MSST draft iteration was reviewed by 163 VA staff (mostly physical therapists and occupational therapists) amongst simulation scenarios and provided content validity, and additional insight and suggestions. Revisions were made to create the final VA MSST which was evaluated by over 200 healthcare workers from varied disciplines (including medical doctors, advanced practice registered nurses, registered nurses, licensed practical nurses, certified nursing assistants, occupational therapists, physical therapists, speech therapists, radiology and ultrasound technicians, etc.). An instruction video and eighteen scenario videos were embedded in an online survey. The survey intended to demonstrate the interrater reliability and validity (concurrent and construct) of the VA MSST. Over 500 VA staff (raters) received a survey invitation via email. RESULTS: Raters (N = 230) from multiple disciplines and healthcare settings independently screened patient mobility status for each of 18 scenarios using the VA MSST. The raters were diverse in their age and years of experience. The estimated interrater reliability (IRR) for VA MSST was excellent and statistically significant with an estimated Krippendorff's alpha (ICC (C, k)) of 0.998 [95% CI: 0.996-0.999]. Eighty-two percent of raters reported that overall VA MSST instructions were clear or very clear and understandable. VA MSST ratings made by technicians and nursing assistants group correlated strongly (r = 0.99, p < 0.001) with the 'gold standard' (experienced physical therapists), suggesting a high concurrent validity of the tool. The VA MSST significantly discriminated between the different levels of patient mobility required for safe mobilization as intended (each difference, p < 0.0001); this suggests a good construct validity. CONCLUSIONS: The VA MSST is an evidence-based flowchart screening and decision support tool that demonstrates excellent interrater reliability across disciplines and settings. VA MSST has strong face and content validity, as well as good concurrent and construct validity.

BACKGROUND: For arteriovenous fistula (AVF) presence of a venous segment with adequate diameter is essential which is lacking in many patients. To find the optimal augmentation technique in patients with small-caliber cephalic vein (i.e., cephalic vein diameter <3 mm), studies compared primary balloon angioplasty (PBA) versus hydrostatic dilation (HD); however, it remained debatable. This systematic review seeks to determine which technique is preferable. METHODS: We searched MEDLINE, PubMed, Embase, and Google Scholar. Primary outcomes were 6-month primary patency, reintervention, and working AVF. Secondary outcomes were immediate success, the AVF's maturation time (day), and surgical site infection. RESULTS: Three randomized controlled trials yielding 180 patients were included, of which 89 patients were in the PBA group. The odds ratio (OR) of primary patency was significantly higher in the PBA group (OR 6.09, 95% confidence interval [CI], 2.36-15.76, P = 0.0002), the OR of reintervention was significantly lower in the PBA group (OR 0.16, 95% CI, 0.06-0.42, P = 0.0002), and the OR of working AVF was greater in PBA group (OR 4.22, 95% CI, 1.31-13.59, P = 0.02). The OR of immediate success was significantly greater in the PBA group (OR 11.42, 95% CI, 2.54-51.42, P = 0.002), and the AVF maturation time was significantly shorter in patients who underwent PBA (mean difference -20.32 days, 95% CI, -30.12 to -10.52, P = 0.0001). The certainty of the evidence was high. CONCLUSIONS: PBA of small cephalic veins with diameter ≤2.5 cm is a safe, feasible, and efficacious augmentation method for AVF creation. This technique achieves favorable maturation outcomes, and PBA is superior to the standard hydrostatic dilatation technique.

Introduction: The virtual learning environment has become increasingly important due to physical distance requirements put in place during the COVID-19 pandemic. The transition to a virtual format has been challenging for case-based teaching sessions, which involve substantial audience participation. We developed a faculty development workshop aimed at teaching health professions educators how to use various interactive virtual tools within videoconferencing platforms to facilitate virtual case-based sessions. Methods: Two 90-minute workshops were piloted as a faculty development initiative. The facilitators demonstrated interactive teaching tools that could be used within virtual case-based sessions. Then, participants discussed how to incorporate these tools into case-based teaching sessions of different class sizes in small-group breakout sessions. Participants completed an online survey following each workshop to evaluate the sessions. Results: A total of 18 and 26 subjects participated in the first and second workshops, respectively. Survey response rates were 100% (n = 18) and 65% (n = 17) for the first and second workshops, respectively. Both groups provided overall high ratings and reported that the workshop was clear, organized, and relevant. Participants were more familiar and comfortable with the use of various interactive tools for online teaching. Discussion: Distance online teaching will be increasingly required for an undetermined time. Faculty development efforts are crucial to facilitate effective interactive teaching sessions that engage learners and maximize learning. This virtual teaching workshop is a simple and straightforward way to introduce a more interactive format to virtual case-based teaching in the health professions.

INTRODUCTION: We report the youngest documented patient (38 years old) to develop an acute popliteal artery thrombus following primary total knee arthroplasty (TKA). PATIENT CONCERNS: The patient presented for an elective TKA secondary to posttraumatic arthritis. Past medical history included a tibial plateau fracture, two knee arthroscopies and an elevated body mass index (37.53). A right TKA was performed with no intraoperative complications. Two hours postoperatively, the right foot was poikilothermic and lacking dorsalis pedal pulse. DIAGNOSIS: Popliteal artery thrombus confirmed by angiogram and venous duplex. INTERVENTIONS: Immediate vascular surgery consult and subsequent embolectomy. OUTCOMES: At 1 year postoperatively, the patient is doing well with no further complications. CONCLUSION: Due to the lack of significant past medical history putting this patient at risk, future research should focus on prior trauma, age, and BMI as risk factors, specifically in patients undergoing TKA.

BACKGROUND: Safe Patient Handling and Mobility (SPHM) programs reduce staff injuries from lifting and repositioning patients. Early Mobility programs improve many patient-centered outcomes. Reframing SPHM equipment as mobilization tools can help safely mobilize hospitalized patients to their highest abilities. PROBLEM: Combining SPHM and Early Mobility programs is logical, but to date, no one has articulated the process of integration. INTERVENTION: A quality improvement process was developed at the Phoenix Veterans Affairs Health Care System to integrate an Early Exercise and Progressive Mobility initiative in the intensive care unit into an ongoing SPHM program using the Iowa Model for Evidence-Based Implementation. RESULTS: Integration of these programs was possible through extensive collaboration between stakeholders throughout planning, implementation, and refinement phases. Interdisciplinary Early Exercise and Progressive Mobility simulation training, standardized assessment, communication of patient status, and appropriate equipment use facilitated staff confidence to safely mobilize patients. CONCLUSIONS: Successful integration of Early Exercise and Progressive Mobility and SPHM was achieved at the Phoenix Veterans Affairs Health Care System.

OBJECTIVE: In accordance with the Kidney Disease Outcomes Quality Initiative recommendations, attaining autogenous hemodialysis access, specifically via creation of radiocephalic arteriovenous fistulas (AVF), brachial-basilic (BB)-AVF, or brachial-cephalic AVFs, is preferred for mortality and morbidity benefits over catheter access in patients with end-stage renal disease. The aim of this study is to determine the suitability of forearm basilic vein transposition (FBVT) fistulas as an alternative access option by comparing outcomes with those of BB-AVFs. METHODS: All patients who underwent creation of FBVT between 2007 and 2015 were identified retrospectively in the electronic medical record and compared with a sample of patients undergoing BB-AVF placement during this time. Access patency was examined using Kaplan-Meier methods and Cox proportional hazards regression. RESULTS: We included 34 patients with FBVT (median age, 54 years; 67.6% male) and 49 with BB-AVF (median age, 57 years; 42.9% male) in this study. There were no significant differences in comorbid conditions between the two groups, with the exception of hyperlipidemia (29.4% FBVT vs 53.1% BB-AVF; P = .03). Although those with FBVT were more likely to have had previous permanent access attempts (70.6% vs 38.7%; P = .002), and access attempts on the same extremity (44.1% vs 24.4%; P = .04), there were no significant differences in primary patency (46.9% vs 53.3%; P = .6), primary-assisted patency (65.6% vs 73.3%; P = .5), or secondary patency (68.8% vs 82.2%; P = .2) at 1 year when compared with BB-AVF. The risk of loss of patency was not statistically different for FBVT as compared with BB-AVF (hazard ratio, 1.37; 95% confidence interval 0.65-2.88; P = .4). This risk did not vary for those who had previous access on the same arm (interaction P = .8). Four fistulas in each group failed to mature. Only one infectious complication was identified in the FBVT group. CONCLUSIONS: No prior studies have directly compared outcomes of FBVTs with BB-AVFs at 1 year or longer. Despite the increased difficulty of harvesting the forearm basilic vein, particularly in patients who have had prior access attempts, there was no significant difference in patency between FBVTs and BB-AVFs. FBVTs are a reasonable option for hemodialysis access, particularly in patients without adequate cephalic veins or who previously failed radiocephalic fistula attempts.

BACKGROUND: We describe the feasibility and long-term outcomes of using femoral vein (FV) for arteriovenous fistula (AVF) and lower extremity bypass (LEB) creation. METHODS: All patients undergoing AVF or LEB using autogenous FV by a single surgeon (April 2006 to September 2013) were reviewed. Perioperative (30-d) complications and long-term outcomes are described. RESULTS: Forty-four patients underwent vascular reconstruction with FV (AVF = 27 and LEB = 17). Perioperative morbidity was 43.2%, including harvest site infection and or seroma in 15.9%. No patients suffered from compartment syndrome or venous thromboembolic event. At median follow-up of 50.0 mon, overall patency was 70.4% for AVF (primary = 37.0% and secondary = 70.3%) and 76.5% for LEB (primary = 70.6% and secondary = 76.5%). Long-term lower extremity swelling occurred in 18.2% of patients. CONCLUSIONS: Perioperative morbidity following FV harvest is high, but long-term patency rates are excellent. FV harvest is feasible and should be considered as a valid conduit in patients without useable great saphenous vein or other more commonly used sources of autogenous vein.

As global controllers of gene expression, small RNAs represent powerful tools for engineering complex phenotypes. However, a general challenge prevents the more widespread use of sRNA engineering strategies: mechanistic analysis of these regulators in bacteria lags far behind their high-throughput search and discovery. This makes it difficult to understand how to efficiently identify useful sRNAs to engineer a phenotype of interest. To help address this, we developed a forward systems approach to identify naturally occurring sRNAs relevant to a desired phenotype: RNA-seq Examiner for Phenotype-Informed Network Engineering (REFINE). This pipeline uses existing RNA-seq datasets under different growth conditions. It filters the total transcriptome to locate and rank regulatory-RNA-containing regions that can influence a metabolic phenotype of interest, without the need for previous mechanistic characterization. Application of this approach led to the uncovering of six novel sRNAs related to ethanol tolerance in non-model ethanol-producing bacterium Zymomonas mobilis. Furthermore, upon overexpressing multiple sRNA candidates predicted by REFINE, we demonstrate improved ethanol tolerance reflected by up to an approximately twofold increase in relative growth rate compared to controls not expressing these sRNAs in 7% ethanol (v/v) RMG-supplemented media. In this way, the REFINE approach informs strain-engineering strategies that we expect are applicable for general strain engineering.
ABSTRACT
Best practice guidelines to avoid pressure ulcers and skin breakdown among obese patients include early and progressive mobility, rigorous turning schedules, and proper skin care. However, implementation of some these guidelines may increase the risk of patient and caregiver injury. An acute care hospital implemented safe patient handling protocols that involved equipment purchase and extensive training for all care staff. The new equipment facilitated repositioning, including boosting and turning, lateral transfers, vertical transfers and ambulation, and bathing and toileting. All healthcare facilities are expected to see an increase in the number of bariatric patients and need for safe patient handling protocols and procedures. At the same time, research is needed to evaluate the safety, effectiveness, and cost-effectiveness of currently available devices designed to improve patient safety and reduce caregiver injury.

OBJECTIVE: We have previously demonstrated an adverse impact of black race and Hispanic ethnicity on the outcomes of carotid endarterectomy (CEA) and carotid artery stenting (CAS). The current study was undertaken to examine the influence of race and ethnicity on the cost of CEA and CAS. METHODS: The Nationwide Inpatient Sample (2005-2009) was queried using ICD-9 codes for CEA and CAS in patients with carotid artery stenosis. The primary outcome was total hospital charges. Multivariate analysis was performed using a generalized linear model adjusting for age, sex, race, comorbidities (Charlson index), high-risk status, procedure type, symptomatic status, year, insurance type, and surgeon and hospital operative volumes and characteristics. RESULTS: Hispanic and black patients were more likely to have a symptomatic presentation, and were more likely to undergo either CEA or CAS by low-volume surgeons at low-volume hospitals (P < 0.05, all). They were also less likely to have private insurance or Medicare (P < 0.001). Overall, CEA was less expensive than CAS over the 4-y study period ($29,502 ± $104 versus $46,713 ± $409, P < 0.001). Total hospital charges after CEA were increased in both blacks ($39,562 ± $843) and Hispanics ($45,325 ± $735) compared with whites on univariate analysis ($28,403 ± $101, P < 0.001). After CAS, total hospital charges were similarly increased in both blacks ($51,770 ± $2085) and Hispanics ($63,637 ± $2766) compared with whites on univariate analysis ($45,550 ± $412, P < 0.001). On multivariable analysis, however, only Hispanic ethnicity remained independently associated with increased charges after both CEA (exponentiated coefficient 1.18; 95% CI [1.15-1.20]; P < 0.001) and CAS (exponentiated coefficient 1.17; 95% CI [1.09-1.24]; P < 0.001). CONCLUSION: Hispanic ethnicity was independently associated with increased hospital charges after both CEA and CAS. The increased charges seen in black patients were explained, in part, by decreased surgeon operative volume and increased postoperative complications. Further efforts are warranted to contain costs in minorities undergoing carotid revascularization.

OBJECTIVES: This study sought to evaluate the short-, intermediate-, and longer-term outcomes after endovascular versus open repair of abdominal aortic aneurysms (AAA), including both AAA-related and all-cause mortality. BACKGROUND: Endovascular stent graft placement for AAA has gained broad acceptance as an alternative to open surgical repair due to a lower perioperative morbidity and mortality. The intermediate- and long-term all-cause and aneurysm-related mortality vary among studies. Thus, we sought to perform a meta-analysis of open versus endovascular repair for treating AAA. METHODS: Electronic databases were queried for identification of prospective, randomized trials of open surgery versus endovascular stent graft repair of AAA. A total of 10 published papers reporting on 6 studies at different follow-up intervals were identified; they involved 2,899 patients with AAA repair procedures, of whom, 1,470 underwent endovascular stent graft AAA exclusion and 1,429 were treated by open AAA repair. RESULTS: At 30 days, the pooled relative risk of all-cause mortality was lower in the endovascular group (relative risk [RR]: 0.35, 95% confidence interval [CI]: 0.19 to 0.64) than in the open surgery group. At intermediate follow-up, the all-cause mortality had a nonsignificant difference (RR: 0.78, 95% CI: 0.57 to 1.08), the AAA-related mortality was significantly lower (RR: 0.46, 95% CI: 0.28 to 0.74) and reintervention rates were higher (RR: 1.48, 95% CI: 1.06 to 2.08) in the endovascular group than in the open surgery group. At long-term follow-up, there was no significant difference in all-cause mortality (RR: 0.99, 95% CI: 0.85 to 1.15) or AAA-related mortality (RR: 1.58, 95% CI: 0.20 to 12.74), whereas the significant difference in the rate of reinterventions persisted (RR: 2.54, 95% CI: 1.58 to 4.08). CONCLUSIONS: In patients randomized to open or endovascular AAA repair, all-cause perioperative mortality, as well as AAA-related mortality at short- and intermediate-term follow-up are lower in patients undergoing endovascular stent graft placement. This was associated with greater reintervention in the endovascular group noted at intermediate follow-up. Long-term survival appears to converge between the 2 groups.

OBJECTIVE: We sought to determine the effects of open (O) and closed (C) cell stents on the size and number of embolic particles generated during carotid artery stenting (CAS) and assess the impact on outcome. METHODS: Embolic debris from carotid filters after CAS was analyzed using photomicroscopy and imaging software. Patient comorbidities, preoperative cerebrovascular symptoms, stent type, and outcomes (perioperative major adverse events) were examined. RESULTS: Carotid filters from 173 consecutive CAS procedures (O, 125 and C, 48) were reviewed. The mean age was 70.9 ± 9.2 years; 58% were men. Mean stenosis was 88.2% ± 8.1%; 36.6% had neurological symptoms preprocedurally. There was no difference in preoperative symptoms between the two groups (O, 38.7% vs C, 31.3%; P = not significant [NS]). However, closed cell stent use was associated with higher degree of stenosis (O, 87.2% ± 8.0% vs C, 90.6% ± 7.8%; P = .01), an older age (O, 70.0 ± 8.6 years vs C, 73.4 ± 10.2 years; P = .03), and peripheral arterial disease (21.1% vs 43.5%; P = .01). A larger mean particle size was observed in patients treated with open cell stents compared to closed cell stents (O, 416.5 ± 335.7 µm vs C, 301.1 ± 251.3 µm; P = .03). There was no significant difference in the total number of particles (O, 13.8 ± 21.5 vs C, 17.6 ± 19.9; P = NS), periprocedural stroke (P = NS), and major adverse events between the two groups (P = NS). CONCLUSIONS: Open cell stents are associated with a larger mean particle size compared to closed cell stents. No impact on procedural outcomes based on stent type was observed.

Safe patient handling and movement (SPHM) programs are effective in reducing healthcare worker injuries. However, the perception among rehabilitation personnel that SPHM equipment promotes patient dependence and adversely affects functional outcomes is one barrier to implementing successful programs. This barrier is particularly evident in acute inpatient rehabilitation facilities, where functional independence is the primary goal. The purpose of this retrospective cohort study was to evaluate this perception. Functional Independence Measure (FIM) ratings were collected from 94 patients with a diagnosis of stroke. Forty-seven patients were admitted 1 year prior to implementation of the SPHM program (Group 1), and 47 were admitted to the facility over a period of 1 year (Group 2) 18 months after program implementation. Group 2 obtained equal or better discharge mobility FIM ratings than Group 1, who received care without the SPHM equipment. This study suggests that SPHM programs do not impede functional outcomes in stroke patients.
