Retrospective Analysis of a Clinical Algorithm for Managing Childhood Myopia Progression.

As the myopia epidemic unfolds, there is growing urgency to identify and implement effective interventions to slow myopia progression. This investigation evaluated the effectiveness of an evidence-based myopia treatment algorithm in a clinical setting among 342 consecutive children. This study aimed to evaluate effectiveness of a clinical treatment algorithm for myopia progression in children. A retrospective cohort analysis was performed using data from myopic children treated for at least 1 year with a defined treatment algorithm incorporating orthokeratology, multifocal lenses, and atropine. The main outcome measures were the percentage of children experiencing ≤0.25 D of myopic cycloplegic spherical equivalent autorefraction (CSER) progression and ≤0.10 mm of axial elongation at 1, 2, and 3 years. The secondary outcome measures were the cumulative absolute reduction of axial elongation values derived from age- and ethnicity-matched virtual control data at 1, 2, and 3 years. Mean annual CSER change values (excluding orthokeratology) were -0.30, -0.20, and -0.13 D at 1, 2, and 3 years, respectively, with 59, 56, and 60% of patients demonstrating ≤0.25 D of change over the prior year. Mean annual axial elongation values were 0.13, 0.12, and 0.09 mm at 1, 2, and 3 years, respectively, with 52, 46, and 65% of patients demonstrating ≤0.10 mm of change over the prior year. The cumulative absolute reduction of axial elongation values were 0.11, 0.20, and 0.29 mm for 1, 2, and 3 years, respectively. The treatment algorithm demonstrated effective control of CSER and axial length in a diverse group of progressive myopic children, supporting its use for the clinical management of childhood myopia.

Deprescribing for older people living in residential aged care facilities: Pharmacist recommendations, doctor acceptance and implementation

BackgroundDeprescribing is an intervention to address the high prevalence of inappropriate polypharmacy in older people living in residential aged care facilities (RACFs). Many deprescribing interventions are complex and involve several stages including initial pharmacist recommendation, subsequent acceptance of the recommendations by a prescriber and the patient, and then actual implementation. ObjectivesThis study aimed to investigate pharmacist deprescribing recommendations for residents within RACFs, general practitioner (GP) acceptance, and the actual implementation of the accepted recommendations at 12-month. MethodsThe intervention occurred as part of a randomised controlled trial and comprised a pharmacist-led medication review using an evidence-based algorithm, with the focus on identifying medications to potentially deprescribe. Consent to participate was obtained from residents (or surrogate decision-makers), RACF nursing staff and the resident's GP. Deprescribing recommendations were reviewed by GPs before implementation as part of the intervention and control arms of the trial, although control group participants continued to receive their usual medications in a blinded manner. ResultsThere were 303 participants enrolled in the study, and 77% (941/1222) of deprescribing recommendations suggested by the pharmacists were accepted by GPs. Of the recommendations accepted by GPs, 74% (692/ 941) were successfully implemented at the end of the follow-up visit at 12 months. The most common reason for deprescribing was because medications were no longer needed (42%, 513/ 1231). ConclusionPharmacist-led deprescribing recommendations arising from an algorithm-based medication review are acceptable to doctors and can have a significant impact on reducing the number of inappropriate medications consumed by older people in RACFs.

899. Evaluation of a Pharmacist-Led Penicillin Allergy Screening Protocol in a Tertiary Care Hospital

Abstract Background Although penicillin allergy is commonly reported, less than 1% of the population are truly allergic to penicillin. False penicillin allergy labelling may be associated with suboptimal antibiotic selection, greater costs, and higher prevalence of antibiotic-resistant organisms. The purpose of this study was to evaluate outcomes of implementing a pharmacist-led penicillin-allergy screening protocol on the antibiotic prescribing habits and the appropriateness of selecting first line antimicrobial therapy. Methods A retrospective, quasi-experimental study included 97 patients with suspected or confirmed common infections. Data was collected between January 2020 to August 2021 for the pre-protocol implementation group (PPG) and between November 2021 to April 2022 for the post-protocol implementation group (PPI). Adults ( > 18 years) with a documented penicillin allergy were included. Patients with penicillin allergy were identified and interviewed by our Emergency Department (ED) clinical pharmacists using an evidence-based algorithm. Data were analyzed using two-sample Student’s t-test and descriptive statistics. Results Fifty-one patients in PPG and 46 in PPI. In the PPG, 60.8% (31/51) had a history of beta-lactam tolerance and 26% (8/31) tolerated at least a penicillin derivative previously. While, twenty-two patients (47.8%) in the PPI tolerated beta-lactams and 50% (11/22) tolerated at least one penicillin derivative. Thirty-eight patients (82.6%) had a documented infection in the PPI and received an antibiotic. The use of Moxifloxacin was significantly lower in the PPI vs the PPG, 0% (0/38) vs 17.6 (9/51) respectively, (P=0.008). However, the use of ciprofloxacin, vancomycin, and aztreonam was lower in the PPI vs the PPG but was not statistically significant (Table 2). Antibiotic therapy appropriateness was higher in the PPI as compared to the PPG, 86.8% (33/38) vs 49% (25/51) respectively, (P=0.0004). In the PPI, documented penicillin allergies were delabeled in 23.9% (11/46) of patients. Conclusion We observed higher rates of appropriate first line antibiotic therapy selection post-implementation of the pharmacist led penicillin allergy screening protocol. This could be an effective strategy to optimize antimicrobial therapy in the hospital setting. Disclosures All Authors: No reported disclosures.

111 POST-OPERATIVE OUTCOME OF ADULT PATIENTS WITH PRE-TRICUSPID SHUNT UNDERGOING DEFECT CLOSURE

Abstract Background patients with pulmonary arterial hypertension (PAH) associated with corrected congenital heart disease (CHD) have a worse prognosis than other 3 groups of patients with PAH associated with CHD (Eisenmenger, small defect, prevalent systemic-to-pulmonary shunt). For this reason, in CHD the indication and timing of defect repair should be evaluated carefully. Current recommendations rely essentially on pulmonary vascular resistance (PVR) when deciding about defect closure, but this may be insufficient as PAH may develop even in cases of normal pre-operative PVR. In particular, patients with PVR below 3 WU are usually deemed operable and patients between 3 and 5 WU (gray zone) are deemed operable in case of significant persistence of left-to-right shunt. Detecting preoperative characteristics of patients who developed PAH after pre-tricuspid shunt repair can be helpful when deciding about CHD correction. Methods we enrolled adult patients referred to our centre for the suspicious of PAH after pre-tricuspid shunt correction from 2006 to 2021. We evaluated clinical, echocardiographic and hemodynamic parameters before and after defect repair (a post-correction hemodynamic evaluation was performed only in case of non-invasive signs of PAH) and PAH after defect closure was defined by the concomitant occurrence of a mean pulmonary artery pressure (mPAP) >25 mmHg and PVR >3 WU. Continuous variables were summarized using mean and standard deviation and Student's t-test was used for comparisons. Results sixty patients were included in the final analysis. After shunt repair, 10 patients (16.6%) were diagnosed with PAH during the long-term follow-up, with no differences given by the type of defect or type of correction. As expected, these patients already had an abnormal baseline hemodynamic profile: 7 had a clear PAH diagnosis before the correction [mPAP >25 mmHg with PVR between 3 and 5 WU and with a pulmonary/systemic cardiac output ratio of at least 1.5] while 3 had pulmonary hypertension related to high pulmonary blood flow (mPAP >25 mmHg and PVR <3 WU). At the baseline hemodynamic evaluation, patients with PAH after shunt repair had higher mPAP (39±6 vs 24±10 mmHg, p <0.001) and PVR (3.7±1.2 vs 1.5±0.9, p <0.001) and lower mixed venous oxygen saturation (81±3 vs 87±3, p <0.001). At the baseline echocardiographic evaluation, patients with PAH after shunt repair had a greater right ventricular hypertrophy (RV wall thickness 0.7±0.1 vs 0.5±0.2 cm, p= 0.011), tricuspid regurgitation jet velocity (424±63 vs 319±62 cm/s, p <0.001) and a significant lower RV fractional area change (34±8 vs 43±9%, p= 0.009). Conclusions currently there are no established evidence-based algorithms to predict the development of PAH after defect correction. Our study shows that this condition may persist or develop even when PVR values are lower than 5 WU despite a significant left-to-right shunt before defect closure. Patients with grey zone PVR values require a global clinical, instrumental and hemodynamic assessment that takes into account more than bare calculated PVR that, especially in patients with a high pulmonary blood flow, can be less reliable.

Parameters associated with successful weaning of veno-arterial extracorporeal membrane oxygenation: a systematic review

PurposeVeno-arterial (VA) extracorporeal membrane oxygenation (ECMO) can be used to restore organ perfusion in patients with cardiogenic shock until native heart recovery occurs. It may be challenging, however, to determine when patients can be weaned successfully from ECMO—surviving without requiring further mechanical support or heart transplant. We aimed to systematically review the medical literature to determine the biomarkers, hemodynamic and echocardiographic parameters associated with successful weaning of VA-ECMO in adults with cardiogenic shock and to present an evidence-based weaning algorithm incorporating key findings.MethodWe systematically searched PubMed, Embase, ProQuest, Google Scholars, Web of Science and the Grey literature for pertinent original research reports. We excluded studies limited to extracorporeal cardiopulmonary resuscitation (ECPR) as the neurological prognosis may significantly alter the decision-making process surrounding the device removal in this patient population. Studies with a mixed population of VA-ECMO for cardiogenic shock or cardiac arrest were included. We excluded studies limited to patients in which ECMO was only used as a bridge to VAD or heart transplant, as such patients are, by definition, never “successfully weaned.” We used the Risk of Bias Assessment tool for Non-Randomized Studies. The study was registered on the International prospective register of systematic reviews (PROSPERO CRD42020178641).ResultsWe screened 14,578 records and included 47 that met our pre-specified criteria. Signs of lower initial severity of shock and myocardial injury, early recovery of systemic perfusion, left and right ventricular recovery, hemodynamic and echocardiographic stability during flow reduction trial and/or pump-controlled retrograde trial off predicted successful weaning. The most widely used parameter was the left ventricular outflow tract velocity time integral, an indicator of stroke volume. Most studies had a moderate or high risk of bias. Heterogeneity in methods, timing, and conditions of measurements precluded any meta-analysis.ConclusionsIn adult patients on VA-ECMO for cardiogenic shock, multiple biomarkers, hemodynamic and echocardiographic parameters may be used to track resolution of systemic hypoperfusion and myocardial recovery in order to identify patients that can be successfully weaned.Graphical

Nutrition issues in the general medical ward patient: From general screening to specific diagnosis and individualized treatment.

Disease-related malnutrition in patients in the general medical ward remains a complex syndrome, which contributes to high morbidity and mortality, and seriously interferes with recovery from acute illness. Recently, there have been important advances in the development of consensus diagnostic criteria for malnutrition, and through the recent completion of large-scale trials, the understanding of pathophysiological pathways and evidence-based treatment algorithms to provide nutrition care to patients at risk for malnutrition in the hospital setting has advanced. There is need to identify more specific clinical parameters and blood biomarkers, which allow a more personalized approach to the malnourished patients, because not all patients show the same response to nutrition interventions. Recent studies have suggested that some nutrition biomarkers of inflammation, kidney function and muscle health, among others, predict treatment response to nutrition interventions and may help to personalize treatments. In addition to advancing the science, there is need for more education of students and treating teams in the hospital to improve the screening of patients at hospital admission regarding nutrition risk with the start of individualized nutrition support interventions, thereby bringing optimal nutrition care to the bedside.

Saving the Exposed Deep Brain Stimulation Implant: A Comprehensive Review of Implant Extrusion and Reconstructive Options

Deep brain stimulation (DBS) for the treatment of Parkinson disease is susceptible to complications, such as hardware extrusion, most commonly at the scalp and chest. The authors describe their experience with the management of hardware extrusion and reconstruction with one of the largest single-institution experience and suggest an evidence-based treatment algorithm for the management of such cases. A retrospective review of hospital records was performed to identify patients who underwent DBS-related surgery and reconstruction from January 2015 to April 2020. Management of these patients involved culture-directed antibiotics, local wound debridement, various forms of reconstruction, and hardware removal when indicated. Ninety-four patients with 131 DBS-related procedures were included. Twelve patients (12.8%) had hardware extrusion, of which 6 occurred primarily at the scalp and 6 occurred primarily at the chest. Primary closure of scalp wounds (odds ratio, 0.05 [0.004-0.71], P = 0.035) was negatively associated with treatment success. The type of reconstruction of chest wounds did not affect its success ( P = 0.58); however, none of them involved a new surgical bed, such as contralateral or hypochondrial placement. Hardware extrusion is a significant complication of DBS-related surgery. Management of extrusion at the scalp should involve the use of tension-free, well-vascularized locoregional flaps as opposed to primary closure. Implantable pulse generator extrusions at the chest can be managed with both primary closure and repositioning in a new surgical bed. Extruded DBS implants may be salvaged with appropriate reconstructive considerations, and the authors suggest an evidence-based treatment algorithm.

Implementing Screening for Nonalcoholic Fatty Liver Disease in Endocrinology Clinics

Nonalcoholic fatty liver disease (NAFLD) in patients with type 2 diabetes (T2D) remains underrecognized by health care providers. The primary purpose of this quality improvement project was to increase identification of NAFLD among patients with T2D followed in an endocrinology practice using an evidence-based algorithm to risk stratify patients. Pre- and post-intervention analysis revealed a significant 36% increase in screening for NAFLD post-intervention (P < 0.001).

Psychopharmacological Treatment Algorithms of Manic/Mixed and Depressed Episodes in Pediatric Bipolar Disorder.

Introduction: Pediatric bipolar disorder (PBD) is a severe psychiatric illness diagnosed before the age of 18, which is associated with extreme shifts in mood characterized by manic and depressive episodes. In 2005, AACAP published algorithms to guide pharmacological treatment of manic/mixed episodes associated with PBD. At that time, lithium was the only Food and Drug Administration (FDA)-approved treatment for pediatric bipolar manic/mixed episodes. The goal of this article is to review evidence that has emerged since the AACAP algorithm in 2005. Methods: Literature searches were conducted through PubMed and limited to studies published between 2005 and 2021, using keywords that focused on randomized controlled trials (RCTs) for available psychopharmacological medications. In addition, the authors conducted in-depth searches for articles providing evidence for agents included in the 2005 AACAP algorithm. Results: Since the publication of the AACAP algorithm in 2005, multiple RCTs have been conducted in PBD, leading to FDA approval of five medications (aripiprazole, asenapine, olanzapine, quetiapine, and risperidone) for the treatment of manic/mixed episodes and two medications (lurasidone and olanzapine-fluoxetine combination) for the treatment of depressed episodes. Divalproex sodium and oxcarbazepine were studied in pediatric RCTs and failed to separate from placebo. Conclusions: We offer an update to the 2005 AACAP algorithms for the treatment of pediatric bipolar mixed/manic episodes and added an evidence-based algorithm for the treatment of depression in PBD. In addition to treatment algorithms, we review current evidence for efficacy of agents proposed in the AACAP algorithm and provide tables summarizing medication side effects and efficacy.

Improving Bone Health in Patients with Metastatic Prostate Cancer with the Use of Algorithm-Based Clinical Practice Tool.

Background: The bone health of patients with locally advanced and metastatic prostate cancer is at risk from treatment-related bone density loss and skeletal-related events from metastatic disease in bones. Evidence-based guidelines recommend using denosumab or zoledronic acid at bone metastasis-indicated dosages in the setting of castration-resistant prostate cancer with bone metastases and at the osteoporosis-indicated dosages in the hormone-sensitive setting in patients with a significant risk of fragility fracture. For the concerns of jaw osteonecrosis, a dental evaluation is recommended before starting bone-modifying agents. The literature review suggests a limited evidence-based practice for bone health with prostate cancer in the real world. Both under-treatment and inappropriate dosing of bone remodeling therapies place additional risks to bone health. An incomplete dental work up before starting bone-modifying agents increases the risk of jaw osteonecrosis. Methods: We created an algorithm-based clinical practice tool to minimize the deviation from evidence-based guidelines at our center and provide appropriate bone health care to our patients by ensuring indication-appropriate dosing and dental screening rates. This order set was incorporated into the electronic medical record system for ordering a bone remodeling agent for prostate cancer. The tool prompts the clinicians to follow the appropriate algorithm in a stepwise manner to ensure a pretreatment dental evaluation and use of the correct dosage of drugs. Results: We analyzed the data from Sept 2019 to April 2022 following the incorporation of this tool. 0/35 (0%) patients were placed on inappropriate bone modifying agent dosing, and dental health was addressed in every patient before initiating treatment. We compared the change in the practice of prescribing and noted a significant difference in the clinician’s practice while prescribing denosumab/zoledronic acid before and after implementation of this tool [incorrect dosing: 24/41 vs. 0/35 (p < 0.00001)]; and an improvement in pretreatment dental checkup before and after implementation of the tool was noted to be [missed dental evaluation:12/41 vs. 0/35 (p < 0.00001)]. Conclusion: We found that incorporating an evidence-based algorithm in the order set while prescribing bone remodeling agents significantly improved our institutional clinical practice of indication-appropriate dosing and dental screening rates, and facilitated high-quality, evidence-based care to our patients with prostate cancer.

Management of treatment-related sequelae following colorectal cancer.

Colorectal cancer survivors are one of the most rapidly growing groups of patients living with and beyond cancer. In a national multidisciplinary setting, we have examined the extent of late treatment-related sequelae in colorectal cancer survivors and present the scientific evidence for management of these conditions in this patient category with the aim of facilitating identification and treatment. A systematic search for existing guidelines and relevant studies was performed across 16 and 4 databases, respectively, from inception to 2021. This yielded 13 guidelines and 886 abstracts, of which 188 were included in the finalized guideline (231 included for full text review). Secondarily, bibliographies were cross-referenced and 53 additional articles were included. Symptoms have been divided into overall categories including psychosocial, bowel-related, urinary, sexual (male and female), pain/neuropathy and fatigue symptoms or complaints that are examined individually. Merging and grading of data resulted in 22 recommendations and 42 management strategies across categories. Recommendations are of a more general character, whereas management strategies provide more practical advice suited for initiation on site before referral to specialized units. Treatment-related sequelae in colorectal cancer survivors are common and attention needs to be focused on identifying patients with unmet treatment needs and the development of evidence-based treatment algorithms.

Bundled Approach to Improve Inpatient Stroke Recognition and Time to Treatment.

BACKGROUND: Early recognition of inpatient stroke is critical in reducing poor outcomes. A gap in knowledge and recognition of stroke by nursing staff was observed; protocols did not incorporate the Balance, Eyes, Face, Arms, Speech, and Time (BE-FAST) symptom mnemonic, and code stroke documentation was frequently incomplete. PURPOSE: This initiative aimed to improve timely recognition, evidence-based treatment, and nursing documentation of stroke-related symptoms. METHODS: This quality improvement initiative implemented an inpatient nurse-driven code stroke bundle. A pre-post prospective intervention design was implemented over 3 months. Code stroke bundle components included an evidence-based protocol, algorithm, visual aids, and education. Nursing communication and documentation used the BE-FAST mnemonic in a Situation, Background, Assessment, Recommendation format. RESULTS: Nursing stroke knowledge improved 8% (88% vs 96%, P < .001); stroke response times improved 15 minutes (25.9 vs 11 minutes, P = .383), although not significant; the code stroke documentation completion rate was increased 48.1% (0 [0%] vs 13 [48.1%], P < .001); and improved utilization of the BE-FAST tool with Situation, Background, Assessment, Recommendation communication (0 [0%] vs 20 [47.6%], P = < .001) was observed. The code stroke cancelation rate slightly worsened (10 [26.3%] vs 14 [26.9%], P = .949), code stroke notifications for altered mental status improved (15 [39.5%] vs 8 [15.7%], P = .015), and the stroke mimic rate improved (27 [71.1%] vs 35 [67.3%], P = .708). CONCLUSION: Nurses provide hospital patient care continuously and are in a key position to intervene when patients present changes in symptoms. Through education and creating an evidence-based protocol, nurses can impact patient outcomes in early recognition and activation of the code stroke system. Further studies are warranted to refine strategies leading to continued improvement in early stroke identification.

Prevention and treatment of wound infections after caesarean section

Caesarean section (cS) is one of the most common obstetric operations in the world. About 32 % of all births end by caesarean section. Postpartum infection at the surgical site, wound infection and endometritis are the main causes of long stays in maternity hospitals and are a source of additional costs for the healthcare system. In 2–16 % of cases postpartum endometritis develops. Many risk factors for the development of postpartum infections have been described. These include maternal factors (such as tobacco use, inadequate prenatal care, obesity, corticosteroid use; prematurity, multiple gestation, and uterine scar), intrapartum and operative factors (such as chorioamnionitis; premature rupture of membranes; prolonged anhydrous period; prolonged labor , especially a long second period; large incision of the anterior abdominal wall; subcutaneous tissue thickness more than 3 cm; subcutaneous hematoma; lack of antibiotic prophylaxis; rapid labor; massive blood loss during childbirth). Effective measures to reduce the incidence of obstetric infectious complications include prophylactic use of antibiotics (preoperative preparation with first-generation cephalosporins and intravenous azithromycin), preoperative showering with chlorhexidine instead of iodine, shaving immediately before surgery, vaginal sanitation, removal of the placenta by traction of the umbilical cord, suturing of the subcutane-ous tissue, if the depth of the wound is larger than 2 cm and suturing the skin with sutures instead of using staples. Establishing an evidence-based optimal care algorithm for patients after caesarean section can reduce the incidence of serious infectious complications.

Quality improvement project on the development of a management algorithm for iatrogenic perforations and the long-term impact on physician knowledge.

Background and study aims Acute iatrogenic endoscopic perforations (AIEPs) can have high morbidity and mortality, especially colonic perforations. Knowledge of diagnosis and AIEP management can improve patient care. The aims of this study were to: develop an evidence-based AIEP management algorithm; study its short-term and long-term impact on physician knowledge; and evaluate physician knowledge using hypothetical clinical scenarios. Methods An institutional AIEP management algorithm was created using the most current recommendations from the American Society for Gastrointestinal Endoscopy and the European Society of Gastrointestinal Endoscopy. Input from advanced endoscopists, nurses, and anesthesiologists was also obtained. We assessed change in physician knowledge using a 10-item questionnaire before (pretest), a standardized one-page AIEP educational material and algorithm immediately after (post-test) to test short-term retention, and 6 months later (6-month reassessment) to test long-term retention. With the 6-month reassessment, two clinical scenarios based on real AIEP were presented to evaluate application of knowledge. Results Twenty-eight subjects (8 gastroenterology fellows and 20 practicing gastroenterologists) participated in the assessments. Pretest and immediate post-test accuracies were 75 % and 95 % ( P < 0.01), respectively. Six-month reassessment accuracies were 83.6 %, significantly worse compared to post-test accuracies ( P < 0.05), but significantly improved compared to pretest accuracies ( P < 0.05). Accuracies for clinical scenarios #1 and #2 were 67.5 % and 60.3 %, respectively. Fellows had similar accuracies when compared to practicing gastroenterologists. Conclusions Using standardized methodology and a multidisciplinary approach, an AIEP management algorithm was created to improve patient care and alleviate physician and staff stress. In addition, we showed that a one-page educational document on perforations can significantly improve short-term and long-term physician knowledge, although periodic reeducation is needed.

Endoscopic Assessment of Radiological Stage IVA Cervical Cancer: A Bivariate Meta-Analysis Supporting an Evidence-Based Staging Algorithm

<h3>Purpose/Objective(s)</h3> To optimize the use of confirmatory endoscopic exams (cystoscopy/proctoscopy) in the staging of locally advanced cervical cancer (LACC), the present study evaluates the predictive value of radiological exams (CT and MRI) to detect bladder/rectum invasion. <h3>Materials/Methods</h3> A systematic search of databases (PubMed and EMBASE) was performed (CRD42021270329). The inclusion criteria were: a) cervix cancer diagnosis; b) staging CT and/or MRI (index test); c) staging cystoscopy and/or proctoscopy (standard test); and d) numbers of true positives (TP), true negatives (TN), false positives (FP), and false negatives (FN) provided. A random-effects bivariate meta-analysis of positive predictive value (PPV) and negative predictive value (NPV) was performed with moderator analyses by imaging modality (CT and MRI) and prevalence. <h3>Results</h3> Nineteen studies met the inclusion criteria, totaling 3480 and 1641 patients for bladder and rectum analyses, respectively. For bladder invasion (prevalence ranged from 0.9% to 34.5%), the overall PPV was 45% (95% confidence interval, 33%-57%, based on 19 studies). Per subgroup, the PPV was 31% for MRI/prevalence ≤6%, 33% for CT/prevalence ≤6%, and 69% for CT/prevalence >6%. For rectal invasion (prevalence ranged from 0.4% to 20.0%), the overall PPV was 30% (95% confidence interval, 17%-47%, based on 8 studies). Per subgroup, the PPV was 36% for MRI/prevalence ≤1%, 17% for MRI/prevalence >1%, and 38% for CT/prevalence >1%. The overall NPV for bladder invasion and rectal invasion were 98% (95% confidence interval, 97%-99%) and 100% (95% confidence interval, 99%-100%), respectively. Considering prevalence and radiological modality, the point estimate of NPV varied from 95% to 100% for bladder invasion and from 99% to 100% for rectum invasion. <h3>Conclusion</h3> Due to low PPV (<50%) of radiological staging, endoscopic exams may be necessary to correctly assess radiological stage IVA LACC. However, they are not necessary after negative radiological exam (NPV ≥95%).

Invasive Prenatal Diagnostic Testing for Aneuploidies in Singleton Pregnancies: A Comparative Review of Major Guidelines.

Sophisticated screening protocols for genetic abnormalities constitute an important component of current prenatal care, aiming to identify high-risk pregnancies and offer appropriate counseling to parents regarding their options. Definite prenatal diagnosis is only possible by invasive prenatal diagnostic testing (IPDT), mainly including amniocentesis and chorionic villous sampling (CVS). The aim of this comparative review was to summarize and compare the existing recommendations on IPDT from the most influential guidelines. All the reviewed guidelines highlight that IPDT is indicated based on a positive screening test rather than maternal age alone. Other indications arise from medical history and sonography, with significant variations identified between the guidelines. The earlier time for amniocentesis is unequivocally set at ≥15 gestational weeks, whereas for CVS, the earlier limit varies from ≥10 to ≥11 weeks. Certain technical aspects and the overall approach demonstrate significant differences. Periprocedural management regarding Rhesus alloimmunization, virologic status and use of anesthesia or antibiotics are either inconsistent or insufficiently addressed. The synthesis of an evidence-based algorithm for IPDT is of crucial importance to healthcare professionals implicated in prenatal care to avoid unnecessary interventions without compromising optimal prenatal care.

Extremity Ischemia After Jellyfish Envenomation: A Case Report and Systematic Review of the Literature

BackgroundExtremity ischemia and necrosis after jellyfish envenomation can be mutilating and cause long-term functional deficits. The best way to manage these presentations is unknown. ObjectiveThe aim of this review was to establish an evidence-based consensus for the management of extremity ischemia after jellyfish envenomation. MethodsA systematic review of cases of extremity ischemia and necrosis after envenomation by marine cnidarians was performed to clarify what is and what is not known about management and outcomes, to draw conclusions about how best to manage these rare presentations, and to establish an evidence-based algorithm. ResultsThe ischemic sequelae of envenomation typically evolves over a few days. Close medical supervision is necessary to react promptly to the evolving clinical scenario. In the literature, 15 different pharmacologic classes have been used to manage these presentations. Only IV infusions of prostaglandin derivatives and intra-arterial thrombolytics have been found to improve the clinical picture and avoid the need for surgical fasciotomy and debridement in some cases. Anticoagulants, antiplatelet agents, steroids, antibiotics, and nitrates, which are among the most commonly prescribed pharmacologic agents, have not been observed to alter the clinical picture. ConclusionsSurgery for compartment syndrome and necrosis are common sequelae of extremity envenomation by marine cnidarians. Only prompt use of IV prostaglandins or intra-arterial thrombolytics can halt ischemic progression and avoid the need for surgery. An algorithm is proposed to guide management of these rare and mutilative presentations.

Barriers and facilitators for implementation of a digital referral algorithm for inflammatory arthritis - a qualitative assessment in patients and caregivers

PurposeDifficulty to recognize inflammatory rheumatic diseases (IRD) in a primary care setting leads to late referral to secondary care. An evidence-based digital referral algorithm can support early referral, yet implementation in daily practice only succeeds with support of end users. We aim to understand the context of implementing a digital referral algorithm and explore the potential barriers and facilitators to implementation.MethodsThis qualitative study comprised focus groups and an online survey. Focus groups were performed with patients from outpatient rheumatology clinics. Surveys were sent out to general practitioners and rheumatologists distributed over The Netherlands. The presented digital referral algorithm originates from the JOINT referral study. Thematic analysis was used with inductive and deductive approaches.ResultsIn total 26 patients participated distributed over three focus groups, and 215 caregivers (104 rheumatologists, 111 general practitioners) filled out the survey. Both patients and caregivers endorse the need for early referral, and recognize the perceived benefit of the digital algorithm. Potential barriers include the complexity of currently included questions, and the outcome lacking information on what to do with no risk of IRD. In order for implementation to be successful, the inclusivity, accessibility, content and outcome of the algorithm are considered important themes.ConclusionSuccessful implementation of a digital referral algorithm needs a systematic multi-facetted approach, considering the barriers and facilitators for implementation as discussed. Since the majority of identified barriers and facilitators was overlapping between all stakeholders, findings from this study can reliably inform further decision strategies for successful implementation.Supplementary InformationThe online version contains supplementary material available at 10.1186/s12875-022-01858-w.

Implementation of an Evidence-Based Prenotification Process for Patients With Stroke to Improve Neurological Outcomes.

BACKGROUND: Endovascular mechanical thrombectomy can improve clinical outcomes in eligible patients with acute ischemic stroke (AIS), but its efficacy is time dependent. This quality improvement project aimed to examine whether a revised evidence-based neurological deficit algorithm initiated in the emergency department could reduce door-to-groin puncture time to less than 90 minutes and improve neurological outcomes in AIS patients who received mechanical thrombectomy. METHODS: Retrospective chart reviews occurred between September 2020 and April 2021, which included 25 patients. Clinical and time data were collected from AIS patients who were 18 years and older, presented for care with AIS symptoms, and deemed candidates for thrombectomy for a period of 6 months. A revised neurological deficit algorithm was initiated, and education was presented to appropriate staff. Postintervention chart reviews occurred from August 2021 to January 2022, which included 25 patients. RESULTS: Door-to-groin puncture time did not improve to less than 90 minutes; however, there was a slight improvement in time from 106 minutes in the preintervention to 98 minutes in the postintervention ( P = .534). Although the outcome measures were not clinically significant, there was a statistically significant decrease in response time to acute stroke call down ( P < .01). Door-to-computed tomography also improved, which was 14.42 minutes for the preintervention group and 5.25 minutes for the postintervention group ( P < .001). Finally, the mean National Institutes of Health Stroke Scale on discharge for the preintervention group was 11.92, and that of the postintervention group was 6.05 on discharge ( P < .01). CONCLUSIONS: Implementation of the revised neurological deficit algorithm did not decrease the door-to-groin puncture time to less than 90 minutes. After implementation of the revised neurologic deficit algorithm, there were single variable improvements in several benchmarks, and this is a starting point for future quality improvement projects.

Learning the "Science of the Art of Prescribing": From Evidence-based Algorithms to Individualized Medicine in Psychiatric Care.

The purpose of this review is to highlight the limitations of the traditional diagnosis/evidence-based symptom reduction paradigm and advocate for an individualized medicine approach that incorporates psychological and relational aspects of prescribing in addition to the objective patient presentation. Potential barriers, challenges, and proposed future directions for improving education in psychological and relational aspects of prescribing are discussed. Psychological aspects of prescribing, as recently spelled out in the field of psychodynamic psychopharmacology, are generally acknowledged as important, but they do not have a well-defined position in contemporary residency training throughout North America. While residents receive in-depth exposure to diverse aspects of what to prescribe in their psychopharmacological training, and they work with patients' subjective and relational meaning and the quality of the therapeutic alliance in their psychotherapy rotations, an integrated approach to how to prescribe is generally lacking. Despite many legitimate challenges, the authors suggest that teaching an integrated approach that incorporates objective, subjective, and relational factors in the provision of psychopharmacology and utilizing evidence-based principles of individualized care should be prioritized in both residency training and the provision of psychiatric treatment as a whole.
