RESUMEN

BACKGROUND: Lumbar spondylolysis involves a bony defect in the vertebral pars interarticularis, predominantly affecting the lower lumbar spine. This condition is a significant etiological factor in lumbar instability and recurrent lower back pain, particularly in young individuals. While conservative treatments are the primary intervention, they often fail to provide relief, necessitating surgical approaches. Notwithstanding, executing bone grafting and fixation in the pars interarticularis defect simultaneously through minimally invasive surgery remains challenging. METHOD: This study elucidates the biportal endoscopic spinal surgery (BESS) technique, innovatively applied for bone graft repair and percutaneous cannulated screw fixation in a patient with lumbar spondylolysis. We offer a detailed walkthrough of the technical procedures supplemented with follow-up radiographic evidence. RESULTS: The BESS technique facilitated meticulous clearance of the defect site, coupled with bone grafting and cannulated screw fixation, effectively addressing lumbar spondylolysis through a minimally invasive approach. This method holds promise for achieving substantial osseous fusion at the vertebral pars interarticularis defect site. CONCLUSION: The BESS procedure for lumbar spondylolysis ensures a clean and prepared defect site for grafting and encourages successful osseous fusion, spotlighting its potential as a viable surgical strategy in managing this condition.

RESUMEN

BACKGROUND: Disparities in emergency care accessibility exist between health service areas (HSAs). There is limited evidence on whether the presence of an emergency department (ED) that exceeds a certain hospital bed capacity is associated with emergency patient outcomes at the regional level. The objective of this study was to evaluate the effect of HSAs with or without of regional or local emergency centers with 300 or more hospital beds (EC300 or nEC300, respectively) by comparing the 30-day mortality of patients with severe emergency diseases (SEDs) admitted to the hospital through the ED. METHODS: The study retrospectively evaluated data from the National Health Information Database (NHID) of the National Health Insurance Service (NHIS) Claims database and enrolled patients who were admitted from the ED for SEDs. SEDs were defined using ICD-10 (International Classification of Diseases 10th Revision) codes for 28 disease categories with high severity, and 56 HSAs were designated as published by the NHIS. We performed hierarchical logistic regression analysis using multilevel models with the generalized linear mixed model (GLIMMIX) procedure to evaluate whether EC300 was associated with the 30-day mortality of SED patients, adjusting for patient-level, prehospital-level, hospital-level, and HSA-level variables. RESULTS: In total, 662 478 patients were analyzed, of whom 54 839 (8.3%) died within 30 days after hospital discharge. Of the 56 HSAs, 46 (82.1%) were included in the EC300 group. After adjustment for patient-level, prehospital-level, hospital-level, and HSA-level variables, nEC300 was significantly associated with increased 30-day mortality in SED patients (adjusted odds ratio [AOR]: 1.33, 95% CI: 1.137-1.153). In addition, patients who visited EDs with fewer annual SED admissions were associated with higher 30-day mortality. CONCLUSION: nEC300 had a greater risk of 30-day mortality in patients treated with SEDs than EC300. The results indicate that not only the number of EDs in each HSA is important for ensuring adequate patient outcomes but also the presence of EDs with adequate receiving capacity.

RESUMEN

BACKGROUND: In the United States, >3.6 million deliveries occur annually. Among them, up to 20% (approximately 700,000) of women experience postpartum depression (PPD) according to the Centers for Disease Control and Prevention. Absence of accurate reporting and diagnosis has made phenotyping of patients with PPD difficult. Existing literature has shown that factors such as race, socioeconomic status, and history of substance abuse are associated with the differential risks of PPD. However, limited research has considered differential temporal associations with the outcome. OBJECTIVE: This study aimed to estimate the disparities in the risk of PPD and time to diagnosis for patients of different racial and socioeconomic backgrounds. METHODS: This is a longitudinal retrospective study using the statewide hospital discharge data from Maryland. We identified 160,066 individuals who had a hospital delivery from 2017 to 2019. We applied logistic regression and Cox regression to study the risk of PPD across racial and socioeconomic strata. Multinomial regression was used to estimate the risk of PPD at different postpartum stages. RESULTS: The cumulative incidence of PPD diagnosis was highest for White patients (8779/65,028, 13.5%) and lowest for Asian and Pacific Islander patients (248/10,760, 2.3%). Compared with White patients, PPD diagnosis was less likely to occur for Black patients (odds ratio [OR] 0.31, 95% CI 0.30-0.33), Asian or Pacific Islander patients (OR 0.17, 95% CI 0.15-0.19), and Hispanic patients (OR 0.21, 95% CI 0.19-0.22). Similar findings were observed from the Cox regression analysis. Multinomial regression showed that compared with White patients, Black patients (relative risk 2.12, 95% CI 1.73-2.60) and Asian and Pacific Islander patients (relative risk 2.48, 95% CI 1.46-4.21) were more likely to be diagnosed with PPD after 8 weeks of delivery. CONCLUSIONS: Compared with White patients, PPD diagnosis is less likely to occur in individuals of other races. We found disparate timing in PPD diagnosis across different racial groups and socioeconomic backgrounds. Our findings serve to enhance intervention strategies and policies for phenotyping patients at the highest risk of PPD and to highlight needs in data quality to support future work on racial disparities in PPD.

RESUMEN

Objective: Early and accurate prediction of patients at risk of readmission is key to reducing costs and improving outcomes. LACE is a widely used score to predict 30-day readmissions. We examine whether adding social determinants of health (SDOH) to LACE can improve its predictive performance. Methods: This is a retrospective study that included all inpatient encounters in the state of Maryland in 2019. We constructed predictive models by fitting Logistic Regression (LR) on LACE and different sets of SDOH predictors. We used the area under the curve (AUC) to evaluate discrimination and SHapley Additive exPlanations values to assess feature importance. Results: Our study population included 316 558 patients of whom 35 431 (11.19%) patients were readmitted after 30 days. Readmitted patients had more challenges with individual-level SDOH and were more likely to reside in communities with poor SDOH conditions. Adding a combination of individual and community-level SDOH improved LACE performance from AUC = 0.698 (95% CI [0.695-0.7]; ref) to AUC = 0.708 (95% CI [0.705-0.71]; P < .001). The increase in AUC was highest in black patients (+1.6), patients aged 65 years or older (+1.4), and male patients (+1.4). Discussion: We demonstrated the value of SDOH in improving the LACE index. Further, the additional predictive value of SDOH on readmission risk varies by subpopulations. Vulnerable populations like black patients and the elderly are likely to benefit more from the inclusion of SDOH in readmission prediction. Conclusion: These findings provide potential SDOH factors that health systems and policymakers can target to reduce overall readmissions.

RESUMEN

Objective: To summarize the characteristics of the learning curve and the occurrence of postoperative adverse events during the development of unilateral biportal endoscopy (UBE) technique by comparing the clinical data of early and late patients treated with UBE technique. Methods: All patients who underwent single-level UBE technique between April 1, 2020 and December 31, 2021 were selected as the research subjects. According to the surgical options, all patients were allocated into 3 groups: unilateral decompression and discectomy (UDD) group, unilateral laminotomy for bilateral decompression (ULBD) group, and lumbar intervertebral fusion (LIF) group. The first 60 cases from each group were extracted and ranked orderly. The endoscopic operation time, the times of fluoroscopy during non-internal fixation implantation, the postoperative hospital stay, the drainage volume, the decrease of hemoglobin, the decrease of hematocrit, and the adverse events were collected. In each group, the patients were allocated into early and late cases according to the operation sequence. The first 30 cases of each group were classified as early cases, and the last 30 cases as late cases. Statistical analysis was performed on the above observation indicators between the early and late cases, and a scatter plot of relevant data changes was drawn to observe the change trend. Results: Compared with the early cases, the endoscopic operation time and the times of fluoroscopy during non-internal fixation implantation of late cases in each group were significantly lower ( P<0.05); the postoperative hospital stay of late cases in LIF group was significantly shorter ( P<0.05); the decreased values of hemoglobin and hematokrit of late cases in ULBD group and LIF group were significantly lower ( P<0.05); the postoperative drainage volume of late cases in ULBD group significantly decreased ( P<0.05). The endoscopic operation time and the times of fluoroscopy during non-internal fixation implantation of 3 groups showed a significant downward trend. The adverse events occurred in 3 early cases and 1 late case of the UDD group, in 6 and 3 cases of the UBLD group, and 8 and 3 cases of the LIF group, respectively. The difference was not significant between the early and late cases ( P>0.05). Conclusion: In the early practice of UBE technique, there is a high incidence of complication, and the surgical trauma is relatively large, which is related to the lack of understanding of the UBE technique characteristics and insufficient surgical experience. With the proficiency of surgical techniques and accumulation of experience, the operation time and the incidence of postoperative adverse events were significantly reduced.
