Study Design Retrospective cohort analysis. Objective Identify demographic and clinical predictors for revision discectomy compare postoperative complications between primary microdiscectomy (MD) discectomy. Methods Patients who underwent one-level lumbar MD subsequent disc herniation were identified using the PearlDiver national database. Multivariate regression analysis was performed to identify of discectomy, assess 30-day opioid use, likelihood future fusion. Results Of 52,310 patients...
Painful vertebral osteoporotic compression fractures (OCFs) are often treated with cement augmentation, although controversies exist as to whether or not this increases the secondary fracture risk. Prevention of includes treatment underlying osteoporosis. The purposes study were determine (1) augmentation rate compared nonoperative management, (2) anti-osteoporotic medications reduce fracture, and (3) osteoporosis following OCF.The PearlDiver database was queried for all patients a diagnosis...
Study Design. Retrospective database review. Objective. Compare 1-year episode of care costs between single-level decompression and plus fusion for lumbar stenosis. Summary Background Data. Lumbar stenosis is the most common indication surgery in patients over 65. Medicare direct hospital reached $1.65 billion 2007. Despite being a surgery, there debate as to preferred surgical treatment. Cost-minimization analysis framework that identifies potential cost savings treatment options have...
Concordance, the concept of patients having shared demographic/socioeconomic characteristics with their physicians, has been associated improved patient satisfaction and outcomes in primary care but not studied subspecialty care. The objective this study was to investigate whether value concordance specialty physicians. authors assessed importance subspecialist 2 cohorts participants. first cohort consisted seeking at a multispecialty orthopedic clinic. second volunteer participants...
Retrospective cohort analysis.
The objective of this study is to assess differences in complication profiles between 3-level posterior column osteotomy (PCO) and single-level pedicle subtraction (PSO) as both are reported provide similar degrees sagittal correction.The PearlDiver database was queried retrospectively using International Classification Disease, 9th 10th edition Current Procedural Terminology codes identify patients who underwent PCO or PSO for degenerative spine disease. Patients under age 18 with history...
Increased out-of-pocket costs have led to patients bearing more of the financial burden for their care. Previous work has shown that and distress can affect outcomes, symptoms, satisfaction, adherence treatment. We asked following questions: (1) Does patients' correlate with disability in nonacute orthopaedic conditions? (2) Do patient demographic factors this correlation?We conducted a cross-sectional, observational study new presenting multispecialty clinic complication. Patients completed...
Shared decision-making between patients and physicians involves educating the patient, providing options, eliciting patient preferences, reaching agreement on a decision. There are different ways to measure shared decision-making, including involvement, but there is no consensus best approach. In other fields, have been varying relationships patient-perceived involvement observed in decision-making. The relationship has not studied orthopaedic surgery.(1) Does correlate with measurements of...
Background Complex regional pain syndrome (CRPS) occurs in 2 to 8% of patients that receive open or endoscopic carpal tunnel release (CTR). Because CRPS is difficult treat after onset, identifying risk factors can inform prevention. We determined the incidence following and CTR using a national claims database. also examined whether psychosocial conditions were associated with CTR. Methods accessed insurance diagnostic procedural codes. calculated within 1 year. The response variable was...
PurposeThe average United States adult reads at an eighth-grade reading level. In effort to ensure that patients understand written medical information, the National Institutes of Health and American Medical Association suggest patient-directed material be a sixth- We hypothesized mean level surgical consent forms for hand surgery is not or below (the suggested maximum from Health).MethodsWe conducted retrospective review consecutive used 7 surgeons our institution June, 2017 October, 2017....
Introduction. Shared decision making involves educating the patient, eliciting their goals, and collaborating on a for treatment. Goal elicitation is challenging physicians as previous research has shown that patients do not bring up goals own. Failure to properly elicit patient leads increased misconceptions decisional conflict. We performed randomized controlled trial test efficacy of simple goal tool in improving involvement making. Methods. conducted randomized, single-blind study new...
The influence of health literacy on involvement in decision-making orthopedic surgery has not been analyzed and could inform processes to engage patients. goal this study was determine the relationship between patient's preferred decision-making. We conducted a cross-sectional observational patients presenting multispecialty clinic. Patients completed Literacy Musculoskeletal Problems (LiMP) survey evaluate their Control Preferences Scale (CPS) level Statistical analysis performed with...
Maxillofacial injuries account for an estimated 11% of National Collegiate Athletic Association (NCAA) sport-related and occur at a rate 0.2-1.5 per 1000 athletic events/exposures.The purpose this study was to report the epidemiology, treatment, outcomes maxillofacial in NCAA Division I athletes participating 13 sports. It hypothesized that would be greater than previously reported national registry studies.Descriptive epidemiology study.A single-institution utilized retrieve surgical...
Study Design: Retrospective cohort study. Objective: To analyze the effect of hyperlipidemia (HLD) on postoperative complications in patients who underwent anterior cervical discectomy and fusion (ACDF). Summary Background Data: ACDF represents standard procedure performed for focal nerve root or spinal cord compression with low complication rates. HLD is well known as a risk factor major after vascular transplant surgery, orthopedic surgery. date, there have been no studies spine Patients...
Study Design/Setting Retrospective cohort analysis Objectives This study evaluates utilization and demographic trends for sacroiliac joint (SIJ) fusions across the United States (US). Methods Patients who underwent SIJ fusion from 2010-2021 were identified within PearlDiver national database using International Classification of Disease (ICD-9, ICD-10) Current Procedural Terminology (CPT) codes. Indications trauma, malignancy, or infection excluded. Demographic, clinical, procedure...
Study Design Retrospective Cohort Objectives Cervical radiculopathy and peripheral entrapment neuropathies often have overlapping symptoms that are difficult to distinguish on physical examination. Small-scale studies attempted report the incidence of this phenomenon, called double crush syndrome (DCS), with varying results. The present study aims determine concomitant cervical nerve compression if DCS hypothesis, which states a at one site leaves it more susceptible another, is valid....
Outcomes in rectal cancer are dependent on tumor height. Modalities for assessing height include MRI, endoscopy, and digital exam (DRE). We seek to identify correlations between these modalities. Retrospective analysis of 120 patients at a single institution. Correlation coefficients distance the anal verge DRE were compared by region. The distances (cm) from were: MRI: 6.2 ± 3.0, endoscopy: 5.9 2.9, DRE: 5.4 2.4 (p = 0.238). Endoscopy strongly correlated with MRI (spearman coefficient 0.899...
Patients have limited involvement in the development of quality measures that address experience undergoing total joint arthroplasty (TJA). Current may not fully assess aspects care are important to patients. The goal this study was understand TJA from patient perspective by exploring patients' knowledge gaps, experiences, and goals. authors completed a prospective qualitative analysis patients who had undergone hip or knee TJA. an open-ended, structured questionnaire about surgical recovery...
