Short-term adverse event rates and risk factors following total elbow arthroplasty for fracture and arthropathy: a matched analysis of nationally representative data

BackgroundTotal elbow arthroplasty (TEA) is a mainstay treatment for elbow arthropathy and elbow fracture that can relieve pain and restore functional motion. The purpose of this study was to determine the role of surgical indication in the incidence of short-term adverse events and risk factors influencing complications in TEA to treat arthropathy compared to TEA for fracture. Matched cohorts were created to better isolate the impact of the surgical indication.MethodsThe study identified patients within the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database that underwent TEA to treat arthropathy or fracture from 2010 to 2020. Matched cohorts were created to analyze the incidence of 30 day adverse events and risk factors for complications.ResultsThe study included 599 patients for analysis. The overall incidence of any adverse event was 9.7%. In matched cohorts of 218 patients, the fracture group experienced a higher incidence of overall adverse events (13.8% vs. 6.0% in the arthropathy group, p = 0.009) and postoperative transfusions (9.6% vs. 1.8% in the arthropathy group, p < 0.001). Logistic regression revealed an increased risk of any adverse event in the combined matched cohort with longer operative times (OR = 1.007, CI: 1.002–1.012, p = 0.006) and those undergoing fracture treatment (OR = 2.447, CI: 1.047–5.717, p = 0.039). Outpatient status was associated with a lower risk of adverse events in the combined matched cohort (OR = 0.207, CI: 0.058–0.739, p = 0.015).ConclusionsEven when controlling for comorbidities, patients undergoing TEA for fracture have a greater likelihood of short-term complications, particularly requiring a blood transfusion. Treatment of a fracture and increased operative time were risk factors for all patients, while outpatient status was protective.Level of evidenceIII.

Association of Clinical and Paraclinical Factors with Pain Crisis Severity in Sickle-Thalassemia Patients in Iran

Objectives: This study aimed to evaluate the effects of several factors, including hospitalization frequency, inflammatory and hemolytic markers, and the numbers of blood transfusions and crises, on the severity of pain crises in sickle-thalassemia patients. Methods: Of all patients visiting hematologists in university-affiliated hospitals and clinics, only 75 sickle cell disease (SCD) and sickle-thalassemia patients met the inclusion criteria for this study. Disease severity was measured based on pain crises per year and laboratory markers, including hemolytic and inflammatory indicators, outpatient or inpatient status, the number of hospital admissions, and the number of blood units transfused over one year. Results: In sickle cell patients, a significant correlation was observed between hospital admission and WBC (0.01), ALP (0.001), MCHC (0.001), ferritin (0.021), and ESR (0.006). Additionally, pain crises were positively correlated with transferrin saturation (TS) (+0.28) and the number of transfused blood units (+0.49) and negatively correlated with Hb (-0.30) and total iron binding capacity (TIBC) (-0.23). Blood unit transfusions showed a positive correlation with serum iron (+0.44), RDW (+0.36), ferritin (+0.39), pain crises (+0.49), and TS (+0.49), along with a negative correlation with Hb (-0.75) and MCHC (-0.33). When categorizing pain crises into two groups, patients experiencing more frequent crises generally exhibited lower hemoglobin levels and a higher number of blood units transfused. Hemoglobin also showed a significant negative correlation with lactate dehydrogenase (LDH) level in both groups: -0.604 (P = 0.005) in patients with ≥ 3 crises per year and -0.368 (P = 0.006) in patients with &lt; 3 crises per year. Patients with hemoglobin levels of 7.5 or higher tended to maintain an LDH level below 1000. Among patients referred with pain crises, hemoglobin was negatively correlated with hemolytic markers such as LDH (-0.41) and retic (-0.29). Conclusions: Hemoglobin and LDH can serve as follow-up markers, as they are routinely measured in all sickle cell patients and, in this study, hemoglobin levels of 7.5 or higher and LDH levels below 1000 were associated with fewer and less severe pain crises. Regular monitoring of hemolytic markers may help in pain crisis prevention, as this study found that hemolytic crises frequently coincided with pain crises. Further research is needed to provide conclusive evidence in this area.

Risk factors for adverse events after clavicle fracture open reduction and internal fixation: A NSQIP study

BackgroundMidshaft clavicle fractures are often subject to increased complications when treated nonoperatively, so surgical treatment with open reduction and internal fixation (ORIF) is a favored alternative. Despite safer outcomes, adverse events such as surgical site infections may still persist, particularly in the presence of certain patient characteristics. The objective of this study was to determine risk factors for and the frequency of adverse events following ORIF for clavicle fractures. MethodsA retrospective review of the National Surgical Quality Improvement Program (NSQIP) database from 2012 to 2021 identified patients undergoing isolated ORIF for clavicle fractures. Patient demographics and 30-day complications were collected. Bivariate analyses with a student's t-test or chi-square test were used to identify possible predictor variables for either AAE or SSI, and demographic metrics with P < 0.2 were included in a multivariable regression model. Multivariable analyses identified significant independent patient risk factors for any adverse event (AAE) or SSI within 30-days of surgery. Adjusted odds ratios were reported for each variable included in the model. Statistical significance was set a prior at P < 0.05. ResultsThe 6,753 selected patients who underwent ORIF for clavicle fractures between 2012 and 2021 were 38.1 ± 15.3 years of age, BMI 26.2 ± 4.9 kg m-12, and 77.3 % male. Of this cohort, 88.4 % received treatment on an outpatient basis. Postoperative adverse events were experienced by 128 (1.9 %) patients within 30 days of surgery, and SSI were prevalent in 0.77 % of patients, followed by wound dehiscence in 0.12 % of patients. After controlling for patient demographics and comorbidities, notable risk factors for adverse events included current smoking status (OR=2.036; P < 0.001) and patient age (OR=1.025; P < 0.001). Outpatient status (OR=0.528; P = 0.004) was protective. ConclusionThe present study noted significantly increased risk of postoperative adverse events in older patients, as well as patients who smoke. Outpatient setting was significantly protective for adverse events. These findings help to provide further clinical context to guide surgical decision making and inform surgeons on current risks and outcomes.

Predictors of 30-day complications, readmission, and postoperative length of stay in children undergoing autologous rib grafting for microtia

BackgroundPredictors of outcomes in pediatric microtia surgery are not well understood within the current literature. A multi-institutional database study may reveal insights into these predictors. ObjectivesTo explore predictors of 30-day complications, 30-day readmission, and postoperative length of stay (PLOS) in pediatric microtia patients undergoing autologous rib grafting. MethodsThe Pediatric National Surgical Quality Improvement Program was queried for patients with microtia (ICD-9/10 744.23/Q17.2) who underwent autologous rib grafting (CPT 21230) between 2012–2021. Demographics, comorbidities, inpatient status, 30-day complications, PLOS, and 30-day readmissions were analyzed. Statistical analyses were performed to compare preoperative characteristics with postoperative outcomes. Results667 patients met inclusion criteria. 63 (9.4%) had at least one complication and 19 (2.9%) were readmitted. Univariate analysis showed inpatient status (p=0.011) and race (p=0.023) were associated with higher complication rates. Multivariate analysis revealed that outpatient status was associated with significantly lower odds of complications (OR: 0.49, 95% CI [0.27, 0.87], p=0.018), and developmental delay was associated with higher odds of 30-day readmission (OR: 2.80, 95% CI [1.05, 7.17], p=0.036). Longer operative time was associated with older age (13.9% increase per five-year age increase, p<0.001) and inpatient status (35.3% increase, p<0.001). Postoperative length of stay was shorter for outpatients (45.45% shorter, p<0.001) and cases performed by plastic surgeons (14.2% shorter, p<0.001). ConclusionMicrotia reconstruction with autologous cartilage is a relatively safe procedure with low complication and readmission rates. Significant predictors of postoperative outcomes include inpatient status, race, developmental delay, and age. These findings highlight the importance of considering these factors in surgical planning and patient counseling.

Revision of antifungal strategies definitions for invasive fungal infections (proven/probable/possible) in 461 patients with haematological malignancies (REDEFI-SEIFEM).

Invasive fungal infections (IFI) are a relevant cause of morbidity and mortality among patients with haematological neoplasms (HMs). Since 2002, a classification of IFI based on host factors, clinical and radiological features and mycological tests was published for research purpose. These criteria are widely used in clinical practice to identify patients at risk for IFI. The aim of the study was to evaluate the clinical applicability of EORTC/MSG 2008 criteria for the diagnosis of IFI in daily practice. This multicentre, non-interventional, observational, prospective study gathered all consecutive inpatients with HMs in which an intravenous antifungal treatment was started. Exclusion criteria were a previous or concomitant transplant procedure, outpatient status and oral antifungal therapy. EORTC/MSG 2008 criteria were used to classify patients at the beginning of antifungal therapy and at 30 days. An independent board reviewed the classification of IFI given by local clinicians at T0 and T30. The highest percentage of agreement was found for possible IFI (96%), while a lower agreement was reported for proven IFI (74%), and the highest variability was observed for probable IFI (56%). At T30, the board re-evaluation confirmed a strict agreement for possible IFI only (98%). Among 306 patients classified as possible, 156 (51%) patients showed non-typical radiological findings and 45 (15%) patients presented host factors only. In real life, the EORTC/MSG criteria can be applicable only for possible IFI. As non-typical radiological findings are reported in possible IFI, introducing a new IFI category should be considered.

Risk factors and incidence of short-term complications following open reduction and internal fixation of scapula fractures

PurposeTo determine the short-term complication rates following open reduction and internal fixation of scapula fractures, factors affecting the development of adverse events, and complication rates based on the anatomic location of the fracture.MethodsThirty-day complication rates for patients who underwent open reduction and internal fixation of the scapula were compared between glenoid, body, coracoid, and acromion fracture locations, as identified by International Classification of Disease codes. Possible adverse events included postoperative surgical site infection, renal insufficiency, intubation, pneumonia, deep vein thrombosis, pulmonary embolism, urinary tract infection, wound dehiscence, stroke, and blood transfusion.ResultsA total of 251 scapula fractures were identified, with 161 having known fracture locations: 105 glenoid, 20 body, 9 coracoid, and 27 acromial fractures. The rate of any adverse event for all scapular fractures was 2.0%, with no significant difference between anatomic locations (p = 0.79). The overall rates of transfusion, surgical site infection, and return to OR were 0.4%, 0.8%, and 3.98%. Steroid use associated with a significantly increased risk of any adverse event (OR: 55.57, p = 0.038) and outpatient status demonstrated a protective effect on reoperation (OR: 0.11, p = 0.014). There were no significant differences in the rates between groups [transfusion (p = 0.91); surgical site infection (p = 0.17); reoperation (p = 0.85)].ConclusionComplication rates within thirty days of ORIF for scapula fracture were low. Reoperation was the most common complication, followed by surgical site infection, wound dehiscence, stroke, transfusion, and pneumonia. Steroid use was a risk factor for developing any adverse event, and outpatient status was protective against reoperation. The 30-day complication profile of glenoid, body, coracoid, and acromial fractures was not significantly different. The low complication rates support the relative short-term safety of operative intervention with internal fixation.Level of EvidenceLevel III.

Ketamine vs Electroconvulsive Therapy for Treatment-Resistant Depression

The ELEKT-D: Electroconvulsive Therapy (ECT) vs Ketamine in Patients With Treatment Resistant Depression (TRD) (ELEKT-D) trial demonstrated noninferiority of intravenous ketamine vs ECT for nonpsychotic TRD. Clinical features that can guide selection of ketamine vs ECT may inform shared decision-making for patients with TRD. To evaluate whether selected clinical features were associated with differential improvement with ketamine vs ECT. This secondary analysis of an open-label noninferiority randomized clinical trial was a multicenter study conducted at 5 US academic medical centers from April 7, 2017, to November 11, 2022. Analyses for this study, which were not prespecified in the trial protocol, were conducted from May 10 to Oct 31, 2023. The study cohort included patients with TRD, aged 21 to 75 years, who were in a current nonpsychotic depressive episode of at least moderate severity and were referred for ECT by their clinicians. Eligible participants were randomized 1:1 to receive either 6 infusions of ketamine or 9 treatments with ECT over 3 weeks. Association between baseline factors (including 16-item Quick Inventory of Depressive Symptomatology Self-Report [QIDS-SR16], Montgomery-Asberg Depression Rating Scale [MADRS], premorbid intelligence, cognitive function, history of attempted suicide, and inpatient vs outpatient status) and treatment response were assessed with repeated measures mixed-effects model analyses. Among the 365 participants included in this study (mean [SD] age, 46.0 [14.5] years; 191 [52.3%] female), 195 were randomized to the ketamine group and 170 to the ECT group. In repeated measures mixed-effects models using depression levels over 3 weeks and after false discovery rate adjustment, participants with a baseline QIDS-SR16 score of 20 or less (-7.7 vs -5.6 points) and those starting treatment as outpatients (-8.4 vs -6.2 points) reported greater reduction in the QIDS-SR16 with ketamine vs ECT. Conversely, those with a baseline QIDS-SR16 score of more than 20 (ie, very severe depression) and starting treatment as inpatients reported greater reduction in the QIDS-SR16 earlier in course of treatment (-8.4 vs -6.7 points) with ECT, but scores were similar in both groups at the end-of-treatment visit (-9.0 vs -9.9 points). In the ECT group only, participants with higher scores on measures of premorbid intelligence (-14.0 vs -11.2 points) and with a comorbid posttraumatic stress disorder diagnosis (-16.6 vs -12.0 points) reported greater reduction in the MADRS score. Those with impaired memory recall had greater reduction in MADRS during the second week of treatment (-13.4 vs -9.6 points), but the levels of MADRS were similar to those with unimpaired recall at the end-of-treatment visit (-14.3 vs -12.2 points). Other results were not significant after false discovery rate adjustment. In this secondary analysis of the ELEKT-D randomized clinical trial of ECT vs ketamine, greater improvement in depression was observed with intravenous ketamine among outpatients with nonpsychotic TRD who had moderately severe or severe depression, suggesting that these patients may consider ketamine over ECT for TRD.

Effects of pulmonary rehabilitation on functional and psychological parameters in post-acute sequelae of SARS-CoV-2 infection (PASC) patients

BackgroundCOVID-19 survivors may develop long-term symptoms of fatigue, dyspnea, mental health issues, and functional limitations: a condition termed post-acute sequelae of COVID-19 (PASC). Pulmonary rehabilitation (PR) is a recommended treatment for PASC; however, there is a lack of data regarding PR’s effect on multiple health indices and the factors that influence patient outcomes. The aim of our study is to evaluate the impact of pulmonary rehabilitation on functional and psychological parameters in patients diagnosed with Post-Acute Sequelae of SARS-CoV-2 Infection (PASC), thereby offering insights into the efficacy of such interventions in improving the quality of life and clinical outcomes for these individuals.MethodsWe extracted patient demographic, comorbidity, and outcome data from Allegheny Health Network’s electronic medical records. Functionality test results were compared before and after PR, including 6-minute walk test (6MWT), chair rise repetitions (CR reps), timed up and go test (TUG), gait speed (Rehab gait), modified medical research council scale (MMRC), shortness of breath questionnaire (SOBQ), hospital anxiety and depression scale (HADS) and chronic obstructive pulmonary disease assessment test (CAT) scores. Multiple regression analysis was done to evaluate the effect of comorbidities and patient factors on patient responses to PR.ResultsThe 55 patients included in this study had a mean time of 4 months between the initial COVID-19 diagnosis and the subsequent PASC diagnosis. Following pulmonary rehabilitation (PR), significant improvements were observed across various metrics. The distance covered in the 6-minute walk test (6MWT) increased markedly from a pre-rehabilitation average of 895 feet (SD 290) to 1,300 feet (SD 335) post-rehabilitation, with a mean change of 405 feet (95% CI [333, 477]). Chair rise repetitions (CR reps) saw an increase from 9 (SD 3) reps to 13 (SD 3) reps, with a change of 4 reps (95% CI [3.7, 4.9]). The timed up and go test (TUG) time decreased significantly from 13 s (SD 5) to 10 s (SD 2), reflecting a mean reduction of 3 s (95% CI [-4.5, -2.5]). Rehabilitation gait speed improved from 1.0 m/s to 1.3 m/s, changing by 0.3 m/s (95% CI [0.2, 0.3]). The Modified Medical Research Council (MMRC) dyspnea scale showed a notable decrease from a mean of 2 (SD 1) to 1 (SD 1), a change of -1 (95% CI [-1.5, -1]). The Shortness of Breath Questionnaire (SOBQ) scores reduced significantly from 51 (SD 21) to 22 (SD 18), with a change of -29 (95% CI [-34, -23]). The Hospital Anxiety and Depression Scale (HADS) scores decreased from 11 (SD 7) to 8 (SD 7), a reduction of -4 (95% CI [-5, -2]). Lastly, the Chronic Obstructive Pulmonary Disease (COPD) Assessment Test (CAT) scores significantly dropped from 18 (SD 7) to 9 (SD 7), changing by -10 (95% CI [-11, -8]). However, the presence of hypertension, diabetes, chronic lung diseases, outpatient status, and receipt of specific pharmacologic treatments (decadron, decadron + remdesivir, and decadron + remdesivir + tocilizumab) were identified as factors associated with a poor response to PR.ConclusionOur study supports PR as an integrated model of care for PASC patients to improve several physical and mental health indices. The long-term effects of PR on patients’ functional status should be investigated in the future.

Orthostatic Hypotension and Antihypertensive Treatment in Lung Transplant Recipients: A Cross-Sectional Study.

Lung transplant is the ultimate treatment of many end-stage lung diseases. Calcineurin inhibitors, crucial in immunosuppression for lung transplant recipients, are linked to secondary hypertension, necessitating antihypertensive treatment. In addition, lung transplant recipients frequently experience orthostatic hypotension, occasionally stemming from autonomic dysfunction, but also commonly attributed as a negative side effect of antihypertensive treatment. Our study aimed to evaluate the frequency of orthostatic blood pressure irregularities and investigate the involvement of antihypertensive treatment as a potential risk factor in the occurrence among lung transplant recipients. Fifty-six consecutive lung transplant recipients, both inpatient and outpatient, at the University Hospital Zurich (Switzerland) were monitored from 1999 to 2013. Transplant recipients underwent a Schellong test (an active standing test). Our evaluation encompassed their initial traits, such as the existence of supine hypertension. We computed the odds ratio for the comparison of the likelihood of experiencing orthostatic hypotension while using a minimum of 1 type of antihypertensive medication versus absence of antihypertensive drugs. Of the lung transplant recipients, 25% showed a positive Schellong test. Within this group, 64% had supine hypertension, and 29% displayed symptoms of orthostatic hypotension. Among the patients, 71% were using at least 1 type of antihypertensive medication. The odds ratio for showing orthostatic hypotension while taking at least 1 type of antihypertensive drug versus the absence of antihypertensive medications was 1.64 (95% exact CI, 0.39-6.90) with P = .50. This finding remained consistent regardless of age, sex, inpatient or outpatient status, and the duration since transplant. Orthostatic blood pressure dysregulation is prevalent among lung transplant recipients, frequently without noticeable symptoms. In our cohort, the use of antihypertensive medications did not elevate the risk of orthostatic hypotension.

What Does the Military Health System Need to Support Future Combat Operations? Lessons From Aeromedical Evacuations From 2008 to 2020.

Aeromedical evacuations from the past few decades have yielded massive amounts of data that may inform the Military Health System (MHS) on patient needs, specifically for understanding the inpatient and outpatient needs of evacuees. In this study, we evaluate inpatient and outpatient trends based on aeromedical evacuation data from recent conflicts. We anticipate that evacuations requiring MHS inpatient beds are primarily trauma-related and necessitate an increased need for inpatient trauma care. We conducted a descriptive analysis of aeromedical evacuations using the U.S. Transportation Command Regulating and Command & Control Evacuation System database. We queried the database for aeromedical evacuations originating from the U.S. EUCOM and ending in the CONUS, from January 1, 2008 to June 4, 2020. With the resultant data, evacuee demographics were characterized by gender, age, active duty (AD) versus non-AD, and branch of service. Following this, the proportion of battle injury to disease and non-battle injury was categorized by both patient age ranges and year. Additionally, evacuations were stratified by their ICD codes, as well as the primary specialty responsible for care. Lastly, evacuations were categorized by inpatient and outpatient care status. The final dataset yielded 32,485 unique patients. The majority of evacuees were male (86.9%) with a mean age of 29.0 ± 9.6 years. Evacuees were primarily AD Military (96.7%), with the majority of those personnel being in the Army (70.2%). The total number of evacuations steadily increased from 2008 (n = 3,703) until a peak in 2010 (n = 4,929), which was also the peak year for battle injury (n = 1,472). Battle injury was also most prevalent in the 21 to 24 age group (24.7%) and declined in older age groups. Regarding diagnoses, the leading categories were injury/poisoning (33.1%), psychiatric (28.1%), and musculoskeletal (12.1%). As for specialty care of evacuees, psychiatry received the largest share of total evacuations (28.1%), followed by orthopedic surgery (22.7%) and general surgery (8.6%). Looking at proportions of inpatient and outpatient care, the majority of evacuees required outpatient care (65.6%) with a sizable minority requiring inpatient care (34.4%). Inpatient evacuations peaked in 2010 (n = 2,013), accounting for 40.8% of all evacuations that year. Orthopedic surgery had the largest share of inpatient evacuations (27.3%), followed by psychiatry (21.5%) and general surgery (18.2%). As for outpatient care, the specialties with the largest proportion of outpatient evacuations were psychiatry (33.6%), orthopedic surgery (20.3%), and neurology (9.8%). The results of this study reveal what the MHS can expect in future conflicts. Most evacuations are for psychiatric-/injury-/musculoskeletal-related diagnoses, typically requiring care by psychiatrists, orthopedic surgeons, or general surgeons. Outpatient care is important, though it is critical to bolster inpatient care requirements as future conflicts may bring extensive numbers of inpatient casualties. The MHS should program and plan resources accordingly, planning for the care of surgical/injured and psychiatric patients.

Do Patients With Insulin-Dependent and Non-Insulin-Dependent Diabetes Have Different Risks for Complications After Total Ankle Arthroplasty?

Patients with diabetes undergoing total ankle arthroplasty tend to be at greater risk for complications than those without diabetes. However, the effect of diabetes severity and how it impacts the risk for perioperative complications is less clear. The purpose of this study was to compare (1) complications, (2) length of hospital stay, and (3) readmissions within 30 days for total ankle arthroplasty (TAA) patients without diabetes, patients with non-insulin-dependent diabetes, and patients with insulin-dependent diabetes. Using the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database, a total of 1803 patients undergoing TAA between 2007 and 2019 were collected. The relationship between diabetes status (no diabetes [n = 1,589], insulin-dependent [n = 169], and non-insulin-dependent [n = 45]) and outcomes were compared. Multivariate linear regression models were used to adjust for confounding variables such as age, sex, race, body mass index, smoking, steroid use, hypertension, chronic obstructive pulmonary disease, anesthesia type, dyspnea, and outpatient status. Statistical significance was set at P <.05. Insulin-dependent diabetes was an independent risk factor for increased odds of infection within 30 days (odds ratio 6.47, 95% CI 0.79-33.66; P = .043). Hospital length of stay was also increased in patients with non-insulin-dependent diabetes (β = 0.21, 95% CI 0.02-0.40; P = .031) and insulin-dependent diabetes (β = 0.40, 95% CI 0.04-0.76; P = .028). However, neither diabetic state demonstrated a statistically significant increase in readmissions or wound complications within 30 days. Patients with insulin-dependent diabetes included in this cohort were at increased risk of having an infection within 30 days after TAA. Additionally, patients with diabetes status had an increased hospital length of stay. These results can inform patients on their potential outcomes after total ankle arthroplasty based on their diabetes status.

The feasibility of emergency department observation units in the management of mild to moderate hyponatremia

ObjectiveTo describe the feasibility of managing hyponatremia patients under outpatient observation status in an academic medical center, and compare outcomes based on the use of an emergency department observation unit (EDOU). MethodsThis is a retrospective cohort study of emergency department hyponatremic patients managed in four hospitals within a large urban academic medical center over 27 months. All patients had an admit-to-observation order, ICD-10 codes for hyponatremia, and mild (130–135 mmol/L) to moderate (121–129 mmol/L) hyponatremia. Observation settings were divided into two groups: EDOU and Non-Observation Unit (NOU) inpatient beds. Severe hyponatremia (≤120 mmol/L) was excluded. Primary clinical outcomes were inpatient admit rate, length of stay (LOS), total direct cost, the rate of adverse events and 30-day recidivism. Results188 patients were managed as an observation patient, with 64 managed in an EDOU setting (age 74.0 yr, 70.3% female) and 124 managed in a NOU setting (age 71.5 yr, 64.5% female). Patient subgroups were similar in terms of presenting complaints, comorbidities, and medication histories. Initial and final sodium levels were similar between settings: EDOU (125.1 to 132.6 mmol/L) vs NOU (123.5 to 132.0 mmol/L). However, outcomes differed by setting for observation to inpatient admit rate (EDOU 28.1% vs NOU 37.9%, adjusted effect 0.70), overall length of stay (EDOU 19.2 h vs NOU 31.9 h; adjusted effect −10.5 h and total direct cost ($1230 vs $1531; adjusted effect -$167). EDOU sodium correction rates were faster (EDOU 0.44 mmol/L/h vs 0.24 mmol/L/h; adjusted effect 0.15 mmol/L/h) and 30-day recidivism rate was similar (EDOU 13% vs NOU 15%). There were no index visit deaths or intensive care unit admissions. ConclusionManagement of selected hyponatremia patients under observation status is feasible, with the EDOU setting demonstrating lower admit rates, shorter length of stay, and lower total direct costs with similar clinical outcomes.

Comparison of the prognostic value of eight nutrition-related tools in older patients with cancer: A prospective study

ObjectivesThe primary objective of the present study was to evaluate and compare the ability of eight nutrition-related tools to predict 1-year mortality in older patients with cancer. Design, setting and participantsWe studied older patients with cancer from the ELCAPA cohort and who had been referred for a geriatric assessment at one of 14 participating geriatric oncology clinics in the greater Paris area of France between 2007 and 2018. MeasurementsThe studied nutrition-related tools/markers were the body mass index (BMI), weight loss (WL) in the previous 6 months, the Mini Nutritional Assessment, the Geriatric Nutritional Risk Index (GNRI), the Prognostic Nutritional Index, the Glasgow Prognostic Score (GPS), the modified GPS, and the C-reactive protein/albumin ratio. ResultsA total of 1361 patients (median age: 81; males: 51%; metastatic cancer: 49%) were included in the analysis. Most of the tools showed a progressively increase in the mortality risk as the nutrition-related risk category worsened (overall p-values <0.02 for all) after adjustment for age, outpatient status, functional status, severe comorbidities, cognition, mood, cancer treatment strategy, tumour site, and tumour metastasis. All the models were discriminant, with a C-index ranging from 0.748 (for the BMI) to 0.762 (for the GPS). The concordance probability estimate ranged from 0.764 (WL) to 0.773 (GNRI and GPS)). ConclusionAfter adjustment for relevant prognostic factors, all eight nutrition-related tools/markers were independently associated with 1-year mortality in older patients with cancer. Depending on the time or context of the GA, physicians do not always have the time or means to perform and assess all the tools/markers compared here. However, even when some information is missing, each nutritional tool/marker has prognostic value and can be used in the evaluation.

A survey on the willingness of outpatients to participate in fundus examination procedures conducted by ophthalmology training residents in China: A cross-sectional study.

The National Standardized Training for Resident Doctors (STRD) in mainland China encounters many challenges in its implementation. To investigate whether outpatients are willing to undergo indirect ophthalmoscopy examination conducted by ophthalmology residents in the ophthalmology STRD program in China. This study conducted a cross-sectional survey at the Eye Hospital of Wenzhou Medical University between September 2021 and September 2023. A cohort of 300 initial outpatients requiring indirect ophthalmoscopy examinations were enlisted from the outpatient department. Based on whether the patients are willing to undergo an indirect ophthalmoscopy examination by resident doctors, patients were divided into two groups: Group 1 (willing) and Group 2 (unwilling), and their questionnaire responses were comparatively analyzed. A total of 261/300 (87%) valid questionnaires were returned in the survey, which included 149 males and 112 females. No notable gender difference (p = 0.400) or disparity in medical expense categories (p = 0.786) was observed between the two groups. However, variables such as outpatient marital status (p = 0.002), the presence of training faculty during fundus examinations with residents and outpatients (p < 0.001), the demeanor of training residents toward patients (p < 0.001), and the quality of doctor-patient communication (p < 0.001) significantly varied between the groups. The level of outpatients' cooperation with ophthalmology residents during fundus examinations in the Chinese ophthalmology STRD program was observed to be low. Enhancing the presence of training faculty during examinations and enhancing the communication skills of training residents could significantly improve this situation.

Sex-Stratified Predictors of Prolonged Operative Time and Hospital Admission in Outpatient Parathyroidectomy.

Our retrospective database study investigatessex-stratified predictors of prolonged operative time (POT) and hospital admission following parathyroidectomy for primary hyperparathyroidism (PHPT). The 2016 to 2018 American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) was queried for patients with PHPT undergoing parathyroidectomy. Cases analyzed were all outpatient status, arrived from home, coded as non-emergent, and elective. POT was defined by the 75th percentile. Hospital admission was defined as LOS 1day. Univariate and multivariable binary logistic regressions were utilized. Of 7442 cases satisfying inclusion criteria, the majority were female (78.0%) and White (78.5%). Median OT (IQR) for females and males was 77 (58-108) and 81 (61-109) minutes, respectively (P = 0.003). 1965 (33.9%) females and 529 (32.3%) males required hospital admission. Independent predictors of POT included ASA class III/IV (aOR 1.342, 95% CI 1.007-1.788) and obesity (aOR 1.427, 95% CI 1.095-1.860) for males (P < 0.05). Independent predictors of hospital admission included age (aOR 1.008, 95% CI 1.002-1.014), ASA class III/IV (aOR 1.490, 95% CI 1.301-1.706), obesity (aOR 1.309, 95% CI 1.151-1.489), dyspnea (aOR 1.394, 95% CI 1.041-1.865), chronic steroid use (aOR 1.674, 95% CI 1.193-2.351), and COPD (aOR 1.534, 95% CI 1.048-2.245) for females (P < 0.05); and ASA class III/IV (aOR 1.931, 95% CI 1.483-2.516) and bleeding disorder (aOR 2.752, 95% CI 1.443-5.247) for males (P < 0.005). In conclusion,predictors of POT and hospital admission following parathyroidectomy for PHPT differed by patient sex. Identifying patients at risk for POT and hospital admission may optimize healthcare resourceutilization. Level of Evidence: IV.

Race-ethnicity and sex differences in 1-year survival following percutaneous coronary intervention among Medicare fee-for-service beneficiaries.

Existing literature describing differences in survival following percutaneous coronary intervention (PCI)by patient sex, race-ethnicity and the role of socioeconomic characteristics (SEC)is limited. Evaluate differences in 1-year survival after PCI by sex and race-ethnicity, and explore the contribution of SEC to observed differences. Using a 20% sample of Medicare claims data for beneficiaries aged 65+, we identified fee-for-service patients who received PCI from 2007 to 2015. We performed logistic regression to assess how sex and race-ethnicity relate to procedural indication, inpatient versus outpatient setting, and 1-year mortality. We evaluated whether these relationships are moderated by sequentially controlling for factors including age, comorbidities, presence of acute myocardial infarction (AMI),county SEC, medical resource availabilityand inpatient versus outpatient procedural status. We identified 300,491 PCI procedures, of which 94,863 (31.6%) were outpatient. There was a significant transition to outpatient PCI during the study period, especially for men compared with women and White patients compared with Black patients. Black patients were 3.50 percentage points (p < 0.001) and women were 3.41 percentage points (p < 0.001) more likely than White and male patients to undergo PCI at the time of AMI, which typically occurs in the inpatient setting. Controlling for age and calendar year, Black patients were 2.87 percentage points more likely than non-Hispanic White patients to die within 1 year after PCI. After controlling for Black-White differences in comorbidities, the differences in 1-year mortality decreased to 0.95 percentage points, which then became nonsignificant when further controlling for county resources and state of residence. Women were more likely to experience PCI in the setting of AMI and had less transition to outpatient care during the period. Black patients experienced higher 1-year mortality following PCI, which is explained by differences in baseline comorbidities, county medical resources, and state of residence.

Bleeding Risk Factors in Thrombocytopenic Patients with Hematologic Malignancies

Introduction Despite prophylactic platelet transfusions, World Health Organization (WHO) grade ≥ 2 bleeding occurs in 50 to 70% of patients with hematologic malignancies and hypoproliferative thrombocytopenia secondary to therapy and/or underlying disease (Gernsheimer et al, Blood 2022). Anemia (hematocrit, HCT ≤ 25%), coagulopathy (activated partial thromboplastin time ≥ 30s, international normalized ratio ≥ 1.2), and platelet count ≤ 5000/µl were independently associated with increased risk of bleeding in the PLADO (platelet dose) trial of 1272 patients with hypoproliferative thrombocytopenia treated between 2004 to 2007 (Uhl et al, Blood 2017). Updated data on bleeding outcomes and risk of bleeding is lacking. Methods We performed a post-hoc analysis of bleeding outcomes and bleeding risk factors in 330 patients with hematologic malignancy and hypoproliferative thrombocytopenia from therapy and/or underlying disease randomized at 3 institutions to receive either tranexamic acid (TXA) or placebo in the double-blinded, multicenter American Trial to Evaluate Tranexamic Acid Therapy in Thrombocytopenia (A-TREAT) (Gernsheimer et al, Blood 2022). Patients received prophylactic platelet transfusions for a platelet count of ≤ 10,000/µl and WHO grade bleeding was assessed daily for 30 days after a platelet count ≤ 30,000/µl and study drug was started. Study drug was discontinued when platelet count was ≥ 30,000/ul for 46 hours without platelet transfusion support or until a maximum of 30 days after treatment activation, whichever came first. Red blood cell (RBC) transfusion was given according to local standard of care. Cox proportional hazards regression with time-varying covariates was used to assess the association of patient characteristics with the risk of a first major (grade 2+) bleeding event. HCT, platelet count, inpatient vs. outpatient status, steroid treatment, and fever were recorded daily. Patients were censored at the first of time of withdrawal, death, or day 30. Results WHO grade ≥ 2 bleeding occurred in 46% of patients overall with no difference between the TXA and placebo groups (TXA 44% versus placebo 47%, p=0.66). Bleeding rates were highest in allogeneic stem cell transplant patients, followed by chemotherapy, followed by autologous stem cell transplant. Overall bleeding rates by organ system showed oral and nasal (18%), skin (17%), gastrointestinal (11%), and genitourinary (11%) bleeding (Table 1). WHO grade ≥ 2 vaginal bleeding occurred in 28% of patients of childbearing potential despite widespread use of hormonal suppression. In a proportional hazards regression model of time to first bleeding event, undergoing allogeneic stem cell transplant was associated with a non-significant increased hazard of bleeding vs chemotherapy (HR 1.32, 95% CI 0.92-1.89), whereas autologous transplant had significantly lower hazard of bleeding vs chemotherapy (HR 0.39, 95% CI 0.20-0.76) (Table 2). HCT &amp;lt; 21% was associated with increased bleeding risk even after adjusting for severe thrombocytopenia (HR 2.71, 29% CI 1.37, 5.36). Platelet count &amp;lt; 5000/µl was also associated with increased risk (HR 3.33, 95% CI 1.67-6.61). Inpatient status, presence of fever, and age did not significantly impact risk of first bleed. Conclusions The overall rate of WHO grade &amp;gt;2 bleeding was similar to historical literature with lower rates of gastrointestinal bleeding than previously reported (31% in PLADO). Vaginal bleeding was common despite standard use of hormonal suppression in patients of childbearing potential. Platelet count &amp;lt; 5000/µl remains a risk factor for bleeding. Regardless of platelet count, bleeding risk increased with HCT &amp;lt; 21% suggesting a red blood cell transfusion threshold higher than 21% is unlikely to mitigate bleeding. More investigation is needed on strategies to reduce bleeding in this patient population.

Awareness of high and pathological myopia among myopic patients in China: A cross‐sectional multicenter survey

AbstractThis study aimed to investigate the awareness of high and pathological myopia among patients with high myopia. A cross‐sectional multicenter survey involving both physicians and patients was conducted between February and April 2021. The outpatient education status, doctors' expectations toward patient education, patients' awareness of high/pathological myopia, and their access to relevant knowledge were inquired, and the proportions of patients with myopia, including high and pathological myopia, were assessed. In total, the survey involved 6975 physicians and patients with myopia from 161 medical institutions in China. The prevalence of high myopia among patients was 11.3%, with 22.59% having pathological myopia. Among those with pathological myopia, 22.45% experienced high myopia complications. Approximately 48.7% of the physicians believed that patients had only a vague idea about high/pathological myopia, with certain misconceptions. Additionally, most outpatients (61.4%) had no access to specialized staff for patient education. Patients' preferences and requirements for online ophthalmology information varied based on family background, medical history, and cognition toward myopia. This study demonstrated that the awareness level among patients with myopia regarding high and pathological myopia is currently insufficient. Therefore, it is important to enhance education efforts to reduce the incidence of adverse outcomes.

A Survey of the Status of Methadone Switching in Japan Using a Hospital-Based Administrative Claims Database.

Methadone is generally used for the management of cancer pain in patients who cannot obtain adequate analgesia from other strong opioids; however, it has a complicated and inconsistent conversion ratio from pre-switching opioid dosage to methadone. This issue may be pronounced in Japan because only oral tablets are commercially available. We aimed to elucidate the status of methadone switching in Japan, focusing on its dosage. Using a Japanese hospital-based administrative claims database, we included patients who switched to methadone between April 2008 and January 2021. The proportion of methadone switching completion that required more than the defined conversion ratio in the Japanese package insert (called "high-dose methadone switching") was evaluated as a primary endpoint. Other endpoints included "the duration from initiation to completion of methadone switching" and "factors affecting high-dose methadone switching by using multivariate logistic regression analysis". Of 1585 patients who received methadone, 370 were enrolled. Among those, 130 (35.1%) received high-dose methadone switching. The median duration of methadone switching completion (12 days) was longer in the high-dose methadone switching group than in other patients. Four variables were identified as factors affecting high-dose methadone switching. Younger age and outpatient status increased the risk of requiring high-dose methadone switching, whereas the concomitant use of nonsteroidal anti-inflammatory drugs and fentanyl as a pre-switching opioid decreased the risk. In conclusion, more than 30% of the patients underwent high-dose methadone switching and required long completion periods, suggesting that methadone switching remains challenging in Japan.
