National implementation of advanced training in the safety planning intervention in the Department of Veterans Affairs health care system.

The Safety Planning Intervention (SPI) is an evidence-based therapeutic intervention designed to mitigate suicide risk by providing a suicidal individual with a written, personalized safety plan. The Department of Veterans Affairs (VA) has implemented safety planning, but research found variability in the quality of safety plans. To improve quality, the VA developed an Advanced Training in the Safety Planning Intervention (ASPI) that went beyond previous didactic training efforts by emphasizing experiential learning. The aim of this article is to describe the procedures and initial results of VA's competency-based ASPI Training Program. Before training, providers participating in this program uploaded a written, deidentified safety plan completed with a Veteran. Providers then completed four training components, including evaluation of fidelity of written safety plans and competency in SPI during live, standardized roleplays at the conclusion of training, and at a 3-month follow-up evaluation. Of the 409 providers who initiated training, 367 (90%) completed training, 26 (6%) dropped out of training, and 16 (4%) did not meet the competency requirements for training completion. Relative to pretraining, there was a medium to large increase in the effect size of the quality of written Safety Plans at the end of training that was maintained at the 3-month follow-up. Using a standardized, observational measure of SPI competency, 383 of 391 (98%) providers met competency criteria following the training, and 367 of 375 (98%) providers met competency at 3-month follow-up. Findings suggest that ASPI training is effective in helping providers achieve and maintain fidelity in safety planning. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Failed recovery after pancreatoduodenectomy: A significant problem even without surgical complications.

BACKGROUND: The absence of surgical complications has traditionally been used to define successful recovery after pancreas surgery. However, patient-reported outcome measures as metrics of a challenging recovery may be superior to objective morbidity. This study aims to evaluate the use of patient-reported outcomes in assessing recovery after pancreas surgery. METHODS: Patients scheduled for pancreatoduodenectomy were prospectively enrolled between 2016 to 2018. Patient-reported outcomes were collected using the linear analog self-assessment questionnaire preoperatively and on postoperative days 2, 7, 14, 30, and monthly until 6 months. Patients were also asked if they felt fully recovered at 30 days and 6 months. Thirty-day surgical morbidity was prospectively assessed, and the comprehensive complication index at 30 days was used to categorize morbidity as major or multiple minor complications (comprehensive complication index ≥26.2) vs uncomplicated (comprehensive complication index <26.2). Clinically significant International Study Group Pancreas Surgery Grade B and C pancreatic fistulas and delayed gastric emptying were reported. χ2 and Kruskal-Wallis tests were used to assess associations with recovery by 6 months and quality of life throughout the postoperative period. RESULTS: Of 116 patients who met inclusion criteria and were enrolled, 32 (28%) had major or multiple minor complications (comprehensive complication index ≥26.2). Overall, fewer than 1 in 10 patients (7%) reported feeling fully recovered at 30 days postoperatively, whereas 55% reported feeling fully recovered at 6 months. Of patients suffering major morbidity, 62% did not recover by 6 months, whereas 38% of those in the uncomplicated group reported not being recovered at 6 months (P = .03). Patients who experienced delayed gastric emptying reported low quality-of-life scores at 1 month (P = .04) compared to those with no delayed gastric emptying, but this did not persist at 6 months (P = .80). Postoperative pancreatic fistula was not associated with quality of life at 1 or 6 months (both P > .05). In the uncomplicated patients, age, sex, surgical approach, and cancer status were not associated with failed recovery at 6 months (all P > .05), and healthier patients (American Society of Anesthesiologists 1-2) were less likely to report complete recovery (42% vs 69% American Society of Anesthesiologists 3-4, P = .04). With the exception of higher preoperative pain scores (mean 2.3 [standard deviation 2.4] among patients not fully recovered at 6 months vs 1.6 [2.2] among those fully recovered, P = .04), preoperative patient-reported outcomes were not associated with failed recovery at 6 months (all P > .05). However, lower 30-day quality of life, social activity, pain, and fatigue scores were associated with incomplete recovery at 6 months. CONCLUSION: More than 1 in 3 patients with an uncomplicated course do not feel fully recovered from pancreas surgery at 6 months; the presence of surgical complications did not universally correspond with recovery failure. In patients with complications, delayed gastric emptying appears to drive quality of life more significantly than postoperative pancreatic fistula. In patients with uncomplicated recovery, healthier patients were less likely to report full recovery at 6 months. Thirty-day patient-reported outcomes may be able to identify patients who are at risk of incomplete long-term recovery.

The Impact of an Overactive Bladder Care Pathway on Longitudinal Patient Management.

IMPORTANCE: Implementation of an overactive bladder (OAB) care pathway may affect treatment patterns and progression. OBJECTIVES: This study aimed to assess the effect of OAB care pathway implementation on treatment patterns for women with OAB. STUDY DESIGN: This retrospective cohort study evaluated women with OAB, before (January 1, 2015-December 31, 2017) and after (January 1, 2019-December 31, 2021) care pathway initiation. Care pathway use included standardized counseling, early introduction of therapy, and close follow-up. Primary outcomes included OAB medication use, follow-up visits, third-line therapy, and time to third-line therapy. RESULTS: A total of 1,349 women were included: 1,194 before care pathway implementation and 155 after. Patients after implementation were more likely to have diabetes mellitus (P = 0.04) and less likely to smoke (P = 0.01). Those managed via a care pathway were more likely to use any medication or third-line therapy within 1 year after consultation (61.3% vs 25.0%; P < 0.001). This included higher proportions receiving a medication (50.3% [95% confidence interval (CI), 41.8%-57.6%] vs 23.3% [95% CI, 20.9%-25.7%]; P < 0.001) and progressing to third-line therapy (22.6% [95% CI, 15.7%-28.9%] vs 2.9% [95% CI, 2%-3.9%]; P < 0.001). Among those who underwent third-line treatment, care pathway use was associated with shorter time to third-line therapy (median, 10 days [interquartile range, 1-56 days] vs 29 days [interquartile range, 7-191 days]; P = 0.013). Those managed via a care pathway were less likely to have additional clinic visits for OAB within 1 year after initial consultation (12.3% vs 23.9%; P < 0.001). CONCLUSIONS: Use of an OAB care pathway was associated with higher rates of oral medication and third-line therapy yet decreased follow-up office visits. Use of an OAB care pathway may promote consistent and efficient care for women with OAB.

Lessons for the next pandemic: analysis of the timing and outcomes including post-discharge decannulation rates for tracheostomy in severe COVID-19 respiratory failure.

PURPOSE: COVID-19 patients with respiratory failure frequently require prolonged ventilatory support that would typically warrant early tracheostomy. There has been significant debate on timing, outcomes, and safety of these procedures. The purpose of this study was to determine the epidemiological, hospital, and post-discharge outcomes of this cohort, based on early (ET) versus late (LT) tracheostomy. METHODS: Retrospective review (March 2020-January 2021) in a 5-hospital system of ventilated patients who underwent tracheostomy. Demographics, hospital/ICU length of stay (LOS), procedural characteristics, APACHE II scores at ICU admission, stabilization markers, and discharge outcomes were analyzed. Long-term decannulation rates were obtained from long-term acute care facility (LTAC) data. RESULTS: A total of 97 patients underwent tracheostomy (mean 61 years, 62% male, 64% Hispanic). Despite ET being frequently performed during active COVID infection (85% vs. 64%), there were no differences in complication types or rates versus LT. APACHE II scores at ICU admission were comparable for both groups; however, > 50% of LT patients met PEEP stability at tracheostomy. ET was associated with significantly shorter ICU and hospital LOS, ventilator days, and higher decannulation rates. Of the cohort discharged to an LTAC, 59% were ultimately decannulated, 36% were discharged home, and 41% were discharged to a skilled nursing facility. CONCLUSIONS: We report the first comprehensive analysis of ET and LT that includes LTAC outcomes and stabilization markers in relation to the tracheostomy. ET was associated with improved clinical outcomes and a short LOS, specifically on days of pre-tracheostomy ventilation and in-hospital decannulation rates.

Perioperative Outcomes of Vesicovaginal Fistula Repair by Surgical Approach.

IMPORTANCE: Data comparing perioperative outcomes between transvaginal, transabdominal, and laparoscopic/robotic vesicovaginal fistula (VVF) repair are limited but are important for surgical planning and patient counseling. OBJECTIVE: This study aimed to assess perioperative morbidity of VVF repair performed via various approaches. STUDY DESIGN: The American College of Surgeons National Surgical Quality Improvement Program database was used to identify women who underwent transvaginal, transabdominal, or laparoscopic/robotic VVF repair from 2009 to 2020. Associations of surgical approach with baseline characteristics, blood transfusion, prolonged hospitalization (>4 days), and 30-day outcomes (any major or minor complication or return to the operating room) were evaluated with χ 2 , Fisher exact, and Kruskal-Wallis tests. Multivariable logistic regression models assessed the adjusted association of approach with 30-day complications and prolonged hospitalization. RESULTS: Overall, 449 women underwent VVF repair, including 252 transvaginal (56.1%), 148 transabdominal (33.0%), and 49 laparoscopic/robotic procedures (10.9%). Abdominal repair was associated with a longer length of hospitalization (median, 3 days vs 1 day transvaginal and laparoscopic/robotic; P < 0.001), higher risk of prolonged length of stay (abdominal, 21.1%; transvaginal, 4.0%; laparoscopic/robotic, 2.0%; P < 0.001), major complications (abdominal, 4.7%; transvaginal, 0.8%; laparoscopic/robotic, 0.0%; P = 0.03), and perioperative transfusion (abdominal, 5.0%; transvaginal, 0.0%; laparoscopic/robotic, 2.1%; P = 0.01). On multivariable analysis, the abdominal approach was independently associated with an increased risk of prolonged hospitalization compared with laparoscopic/robotic (odds ratio, 12.3; 95% confidence interval, 1.63-93.21; P = 0.02) and transvaginal (odds ratio, 6.09; 95% confidence interval, 2.87-12.92; P < 0.001) but not with major/minor complications ( P = 0.76). CONCLUSION: Transvaginal and laparoscopic/robotic approaches to VVF repair are associated with lower rates of prolonged hospitalization, major complications, and readmission compared with a transabdominal approach.

SARS-CoV-2 vaccine-induced antibodies protect against Omicron breakthrough infection.

SARS-CoV-2 Omicron quickly spread globally, also in regions with high vaccination coverage, emphasizing the importance of exploring the immunological requirements for protection against Omicron breakthrough infection. The test-negative matched case-control study (N = 964) characterized Omicron breakthrough infections in triple-vaccinated individuals from the ENFORCE cohort. Within 60 days before a PCR test spike-specific IgG levels were significantly lower in cases compared to controls (GMR [95% CI] for BA.2: 0.83 [0.73-0.95], p = 0.006). Multivariable logistic regression showed significant associations between high antibody levels and lower odds of infection (aOR [95% CI] for BA.2 spike-specific IgG: 0.65 [0.48-0.88], p = 0.006 and BA.2 ACE2-blocking antibodies: 0.46 [0.30-0.69], p = 0.0002). A sex-stratified analysis showed more pronounced associations for females than males. High levels of vaccine-induced antibodies provide partial protection against Omicron breakthrough infections. This is important knowledge to further characterize a threshold for protection against new variants and to estimate the necessity and timing of booster vaccination.

Omicron Variant-Specific Serological Imprinting Following BA.1 or BA.4/5 Bivalent Vaccination and Previous SARS-CoV-2 Infection: A Cohort Study.

BACKGROUND: Continuous evolution of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) outpaces monovalent vaccine cross-protection to new viral variants. Consequently, bivalent coronavirus disease 2019 (COVID-19) vaccines including Omicron antigens were developed. The contrasting immunogenicity of the bivalent vaccines and the impact of prior antigenic exposure on new immune imprinting remains to be clarified. METHODS: In the large prospective ENFORCE cohort, we quantified spike-specific antibodies to 5 Omicron variants (BA.1 to BA.5) before and after BA.1 or BA.4/5 bivalent booster vaccination to compare Omicron variant-specific antibody inductions. We evaluated the impact of previous infection and characterized the dominant antibody responses. RESULTS: Prior to the bivalent fourth vaccine, all participants (N = 1697) had high levels of Omicron-specific antibodies. Antibody levels were significantly higher in individuals with a previous polymerase chain reaction positive (PCR+) infection, particularly for BA.2-specific antibodies (geometric mean ratio [GMR] 6.79, 95% confidence interval [CI] 6.05-7.62). Antibody levels were further significantly boosted in all individuals by receiving either of the bivalent vaccines, but greater fold inductions to all Omicron variants were observed in individuals with no prior infection. The BA.1 bivalent vaccine generated a dominant response toward BA.1 (adjusted GMR 1.31, 95% CI 1.09-1.57) and BA.3 (1.32, 1.09-1.59) antigens in individuals with no prior infection, whereas the BA.4/5 bivalent vaccine generated a dominant response toward BA.2 (0.87, 0.76-0.98), BA.4 (0.85, 0.75-0.97), and BA.5 (0.87, 0.76-0.99) antigens in individuals with a prior infection. CONCLUSIONS: Vaccination and previous infection leave a clear serological imprint that is focused on the variant-specific antigen. Importantly, both bivalent vaccines induce high levels of Omicron variant-specific antibodies, suggesting broad cross-protection of Omicron variants.

Disparities in Parathyroidectomy: Who Receives Appropriate Treatment for Primary Hyperparathyroidism?

INTRODUCTION: Parathyroidectomy is underperformed despite clear benefits in primary hyperparathyroidism (PHPT). We evaluated disparities in receipt of parathyroidectomy following PHPT diagnosis to explore barriers to care. METHODS: Adults diagnosed with PHPT 2013-2018 at a health system were identified. Recommended indications for parathyroidectomy include age ≤50 y, calcium >11 mg/dL, or the presence of nephrolithiasis, hypercalciuria, nephrocalcinosis, decreased glomerular filtration rate, osteopenia, osteoporosis, or pathological fracture 1 y prior to diagnosis. Kaplan-Meier analysis assessed rates of parathyroidectomy within 12 mo following diagnosis as well as median time to parathyroidectomy, and multivariable Cox proportional hazards analyses assessed factors associated with undergoing parathyroidectomy. RESULTS: Of 2409 patients, 75% were females, 12% aged ≤50 y, and 92% non-Hispanic White, while 52% had Medicaid/Medicare, 36% were commercial/self-pay or uninsured, and 12% unknown. Parathyroidectomy was performed within 1 y in 50% of patients. Within the 68% that met recommendations, parathyroidectomy was performed within 1 y in 54%; median time from diagnosis to surgery was shorter for males, patients aged ≤50 y, commercial/self-pay/no insurance patients (versus Medicaid/Medicare), and those with fewer comorbidities, P < 0.05. Multivariable analysis demonstrated non-Hispanic White patients and those with commercial/self-pay/uninsured were more likely to undergo parathyroidectomy after adjusting for comorbidity, age, and facility site. Among those strongly indicated, patients not on Medicare/Medicaid and aged ≤50 y were more likely to undergo parathyroidectomy after adjusting for race, comorbidity, and facility site. CONCLUSIONS: Disparities in parathyroidectomy for PHPT were observed. Insurance type was associated with undergoing parathyroidectomy; patients on governmental insurance were less likely to undergo surgery and waited longer for surgery despite strong indications. Barriers to referral and access to surgery should be investigated and addressed to optimize all patients' access to care.

Evolution of rehabilitation services in response to a global pandemic: reflection on opportunities and challenges ahead.

The rapidly evolving COVID-19 public health emergency has disrupted and challenged traditional healthcare, rehabilitation services, and treatment delivery worldwide. This perspective paper aimed to unite experiences and perspectives from an international group of rehabilitation providers while reflecting on the lessons learned from the challenges and opportunities raised during the COVID-19 pandemic. We discuss the global appreciation for rehabilitation services and changes in access to healthcare, including virtual, home-based rehabilitation, and long-term care rehabilitation. We illustrate lessons learned by highlighting successful rehabilitation approaches from the US, Belgium, and Japan.

Pathogenic BCS1L Mutation Resulting in Hypertrophic Cardiomyopathy: A Unique Presentation of Nuclear Mitochondrial Disease.

A 21-year-old man with sensorineural hearing loss and glaucoma presented with severely limited exercise capacity since childhood. He was found to have biventricular concentric hypertrophy with greatest wall thickening at the posterior and lateral walls of the left ventricle apex (1.7 cm) and the free wall of the right ventricle (1.1 cm). There was no inducible left ventricular outflow tract obstruction. Metabolic testing revealed marked lactic aciduria (1,650.1 µmol/mmol creatinine) and plasma lactate (3.9 mmol/L). A sarcomeric hypertrophic cardiomyopathy gene panel was unremarkable, but mitochondrial gene analysis revealed a homozygous c.385G>A (p.Gly129Arg) pathogenic mutation in the BCS1L gene. This gene is responsible for an assembly subunit of cytochrome complex III in the respiratory transport chain and is the rarest respiratory chain defect. This gene has not frequently been implicated in cardiomyopathy. Mitochondrial hypertrophic cardiomyopathy is more rare than hypertrophic cardiomyopathy resulting from sarcomeric mutations and is more likely to be symmetric, less frequently results in left ventricular outflow tract obstruction, and is more likely to progress to dilated cardiomyopathy. Evidence-based screening protocols have not been established; treatment follows guideline-directed medical therapy for congestive heart failure, including evaluation for heart transplantation. This report expands the phenotype of the BCS1L mutation and suggests that affected patients may need screening for underlying cardiomyopathy.

Patient Satisfaction Scores Impact Pediatrician Practice Patterns, Job Satisfaction, and Burnout.

Patient satisfaction (PS) surveying has become a commonly used measure of physician performance, but little is known about the impact on pediatricians. To investigate our hypothesis that PS surveys negatively impact pediatricians, we conducted a survey at an academic children's medical center. Of 155 eligible physicians, 115 responded (response rate 74%). Two-thirds (68%) did not find the PS score report useful and 88% did not feel that PS scores accurately reflect the physician's clinical ability. A third reported ordering tests, medications, or consultations due to pressure for higher PS scores. In addition, one-third agreed that PS surveys contribute to burnout and make it difficult to practice meaningful medicine. Overall, PS score reporting has a negative impact on pediatricians, especially those who are female, BIPOC (Black, Indigenous, and People of color), subspecialists, younger, and attended non-US medical schools. Further investigation into improved methods for providing feedback to pediatric physicians is warranted.

Multisite analysis of patient experience scores and risk of hospital admission: a retrospective cohort study.

BACKGROUND: Routinely collected patient experience scores may inform risk of patient outcomes. The objective of the study was to evaluate the risk of hospital admission within 30-days following third-party receipt of the patient experience survey and guide interventions. METHODS: In this retrospective cohort study, we analyzed Hospital Consumer Assessment of Healthcare Providers and Systems surveys, January 2016-July 2019, from an institution's 20 hospitals in four U.S. states. Surveys were routinely sent to patients using census sampling. We analyzed surveys received ≤60 days following discharge from patients living ≤60 miles of any of the institution's hospitals. The exposures were 19 survey items. The outcome was hospital admission within 30 days after third-party receipt of the survey. We evaluated the association of favorable (top-box) vs unfavorable (non-top-box) score for survey items with risk of 30-day hospital admission in models including patient and hospitalization characteristics and reported adjusted odds ratios (aOR [95% confidence interval]). RESULTS: Among 40,162 respondents (mean age ± standard deviation: 68.1 ± 14.0 years), 49.8% were women and 4.3% had 30-day hospital admission. Patients with 30-day hospital admission, compared to those not admitted, were more likely to be discharged from a medical service line (62.9% vs 42.3%; P < 0.001) and have a higher Elixhauser index. Favorable vs unfavorable score for hospital rating was associated with lower odds of 30-day hospital admission in the overall cohort (0.88 [0.77-0.99]; P = 0.04), medical service line (0.81 [0.70-0.94]; P = 0.007), and upper tertile of Elixhauser index (0.79 [0.67-0.92]; P = 0.003). Favorable score for recommend hospital was associated with lower odds of 30-day hospital admission in the medical service line (0.83 [0.71-0.97]; P = 0.02) but for others (e.g. cleanliness of hospital environment) showed no association. CONCLUSION: In routinely collected patient experience scores, favorable hospital rating was associated with lower odds of 30-day hospital admission and may inform risk stratification and interventions. Evidence-based survey items linked to patient outcomes may also inform future surveys.

Operant social seeking to a novel peer after social isolation is associated with activation of nucleus accumbens shell in rats.

RATIONALE AND OBJECTIVE: Deprivation of social interaction promotes social reward seeking in rodents, assessed primarily by the conditioned place preference procedure. Here, we used an operant social procedure in rats and examined the effect of the housing condition (pair-housing vs. single-housing) during or after social self-administration on social reward seeking. METHODS: We first trained paired-housed or single-housed rats to gain access to an age- and sex-matched novel peer. On post-training day 1 (PTD1), we tested both groups for social seeking without the presence of the novel peer. Next, we divided each group into pair-housing or single-housing conditions and tested all four groups (pair-pair, pair-single, single-pair, and single-single) for social seeking on post-training day 12 (PTD12). Finally, we analyzed Fos expression in the striatum associated with social seeking on PTD12. RESULT: Single-housed rats earned more social rewards during social self-administration than pair-housed rats. Social isolation during social self-administration also promoted social seeking on PTD1 and PTD12, regardless of their housing conditions after social self-administration training. Additionally, in pair-housed rats, social isolation during the post-training period led to a time-dependent increase of social seeking on PTD12 compared with PTD1. Finally, the Fos analyses revealed an increase of Fos expression in NAc shell of single-single rats after social seeking test on PTD12 compared with pair-pair rats. CONCLUSION: Our data suggest that social isolation promotes operant social self-administration and social seeking. In addition, neuronal activation of NAc shell is associated with social seeking after social isolation.

Neurodegeneration Markers Galectin-3 and Apolipoprotein E Are Elevated in the Aqueous Humor of Eyes With Glaucoma.

Purpose: Galectin-3 (Gal-3) and apolipoprotein E (APOE) are markers of activated microglia in neurodegenerative diseases of the central nervous system, whose targeting is protective in mouse models of glaucoma. In this study, we examined levels of Gal-3 and APOE in human aqueous humor (AH) and defined their clinical associations with glaucoma. Methods: We collected AH from 59 glaucoma patients and 15 controls at the start of planned ophthalmic surgery. Gal-3 and APOE levels were quantified by enzyme-linked immunosorbent assay. Total protein in AH was quantified by bicinchoninic acid assay. Significant associations between Gal-3, APOE, and clinical covariates were defined using univariate and multivariate linear regression models. Results: Gal-3 and APOE levels were significantly elevated in the AH of glaucoma patients compared to controls (P = 0.004 and P < 0.001, respectively). Gal-3 and APOE were positively correlated across the entire cohort (r = 0.65, P = 6.2E-9). No association was observed between Gal-3 and total protein or APOE and total protein (P = 0.35 and P = 0.50, respectively), indicating that their levels were not increased in glaucomatous AH due to nonspecific protein accumulation. Multivariate linear regression modeling revealed significant associations between Gal-3 and maximum recorded intraocular pressure (P = 0.009) and between APOE and number of past ophthalmic surgeries (P = 0.031). Conclusions: We demonstrate that Gal-3 and APOE are significantly elevated in the AH of eyes with glaucoma and are associated with a history of poorly controlled disease. Translational Relevance: Gal-3 and APOE in AH may inform clinical decision-making as quantifiable readouts of microglial activation in eyes with glaucoma.

Comparison of vaccine-induced antibody neutralization against SARS-CoV-2 variants of concern following primary and booster doses of COVID-19 vaccines.

The SARS-CoV-2 pandemic has, as of July 2022, infected more than 550 million people and caused over 6 million deaths across the world. COVID-19 vaccines were quickly developed to protect against severe disease, hospitalization and death. In the present study, we performed a direct comparative analysis of four COVID-19 vaccines: BNT162b2 (Pfizer/BioNTech), mRNA-1273 (Moderna), ChAdOx1 (Oxford/AstraZeneca) and Ad26.COV2.S (Johnson & Johnson/Janssen), following primary and booster vaccination. We focused on the vaccine-induced antibody-mediated immune response against multiple SARS-CoV-2 variants: wildtype, B.1.1.7 (Alpha), B.1.351 (Beta), B.1.617.2 (Delta) and B.1.1.529 (Omicron). The analysis included the quantification of total IgG levels against SARS-CoV-2 Spike, as well as the quantification of antibody neutralization titers. Furthermore, the study assessed the high-throughput ACE2 competition assay as a surrogate for the traditional pseudovirus neutralization assay. The results demonstrated marked differences in antibody-mediated immune responses. The lowest Spike-specific IgG levels and antibody neutralization titers were induced by one dose of the Ad26.COV2.S vaccine, intermediate levels by two doses of the BNT162b2 vaccine, and the highest levels by two doses of the mRNA-1273 vaccine or heterologous vaccination of one dose of the ChAdOx1 vaccine and a subsequent mRNA vaccine. The study also demonstrated that accumulation of SARS-CoV-2 Spike protein mutations was accompanied by a marked decline in antibody neutralization capacity, especially for B.1.1.529. Administration of a booster dose was shown to significantly increase Spike-specific IgG levels and antibody neutralization titers, erasing the differences between the vaccine-induced antibody-mediated immune response between the four vaccines. The findings of this study highlight the importance of booster vaccines and the potential inclusion of future heterologous vaccination strategies for broad protection against current and emerging SARS-CoV-2 variants.

Collaborative improvement on acute opioid prescribing among diverse health systems.

BACKGROUND: Despite broad awareness of the opioid epidemic and the understanding that patients require much fewer opioids than traditionally prescribed, improvement efforts to decrease prescribing have only produced modest advances in recent years. METHODS AND FINDINGS: By using a collaborative model for shared expertise and accountability, nine diverse health care systems completed quality improvement projects together over the course of one year to reduce opioid prescriptions for acute pain. The collaborative approach was flexible to each individual system's goals, and seven of the nine participant institutions definitively achieved their desired results. CONCLUSIONS: This report demonstrates the utility of a collaborative model of improvement to bring about real change in opioid prescribing practices and may inform quality improvement efforts at other institutions.

The where, when, and why of surgical rib fixation: Utilization patterns, outcomes, and readmissions.

INTRODUCTION: There has been increasing use of surgical stabilization of rib fractures (SSRF), but most literature demonstrate outcomes of single centers during the index hospitalization. We sought to analyze statewide patterns and longer-term outcomes after SSRF. METHODS: Adult patients with >1 rib fracture in the 2016-2018 California Office of Statewide Health Planning Database were identified. SSRF and non-operatively managed (NO) patients were matched on clinical and demographic variables. Patterns and outcomes of SSRF were assessed with multivariate modeling. RESULTS: 599 SSRF patients were matched to 1191 NO patients. Readmission and readmission complication rates were similar between the groups. In a competing risks regression, admission to a high-volume SSRF center (SHR 4.6, CI95 4.0-5.4, p = 0.01) was the primary predictor of SSRF. 30-day mortality adjusted risk was lower for the SSRF vs. NO group (HR 0.47, CI 0.25-0.88, p = 0.02). DISCUSSION: Statewide utilization of SSRF varied widely and appears to be driven by center or surgeon characteristics rather than clinical factors. Efforts to expand access to SSRF based on clinical factors may be warranted.

Is Same-Day Discharge Following Minimally Invasive Sacrocolpopexy Safe and Feasible? A National Contemporary Database Analysis.

OBJECTIVE: The aim of this study was to investigate trends and outcomes of ambulatory minimally invasive sacrocolpopexy (MISC) using data from a contemporary multicenter nationwide cohort. METHODS: We used the American College of Surgeons National Surgical Quality Improvement Program database to identify women who underwent nonemergent MISC (laparoscopic and robotic) from 2012 to 2018. Exclusion criteria were age <18 or ≥90 years, rectal prolapse, postoperative discharge day ≥3, and concomitant hysterectomy, transvaginal mesh repair, colpocleisis, and/or colorectal surgery. Baseline demographics and 30-day outcomes were compared between patients who underwent same-day discharge (SDD; discharge on postoperative day [POD] 0) and those discharged on POD 1-2 using Kruskal-Wallis, Fisher exact, and Pearson χ2 tests. A 2-sided Cochran-Armitage trend test assessed SDD over time, and person-years methodology was used to assess readmission rates. Multivariable logistic regression and Cox proportional hazards modeling evaluated associations between SDD and postoperative outcomes. We hypothesized that SDD increased over the study time frame and is not associated with adverse outcomes. RESULTS: Of 2,928 women, 362 (12.4%) were SDD, and 2,566 (87.6%) were discharged POD 1-2. The proportion of SDD nearly quadrupled over time (5.6% [2012], 20.6% [2018]; P < 0.001). The SDD group was younger (mean age, 61.9 vs 63.6; P = 0.04), with lower proportion of American Society of Anesthesiologists class III or higher (21.8% vs 27.5%; P = 0.02) and hypertension (37.3% vs.46.5%; P < 0.001), shorter total operation time (median, 142 vs 172 minutes; P < 0.001), and fewer concomitant slings (21.5% vs 33.0%; P < 0.001). Outcomes were similar for SDD: 30-day overall complications (3.0% vs 4.4%; P = 0.23), readmissions (1.1% vs 2.0%; P = 0.28), and reoperations (1.1% vs 0.9%; P = 0.55) and persisted with multivariable analysis. CONCLUSION: Ambulatory MISC significantly increased during the study period and appears safe and feasible in select patients.
