Purpose: We sought to characterize trends in demographics, comorbidities, and postoperative complications among patients undergoing primary and revision cervical disc replacement (pCDR/rCDR) procedures. Methods: In this retrospective database study, the Premier Healthcare database was queried from 2006 to 2019. Annual proportions or medians were calculated for patient and hospital characteristics, comorbidities, and postoperative complications associated with CDR surgery. Trends were assessed using linear regression analyses with year of service as the sole predictor. Results: A total of 16,178 pCDR and 758 rCDR cases were identified, with a median (IQR) age of 46 (39; 53) and 51 (43; 60) years among patients, respectively. The annual number of both procedures increased between 2006 and 2019, from 135 to 2220 for pCDR (p < 0.001), and from 17 to 49 for rCDR procedures (p < 0.001), with radiculopathy being the main indication for surgery in both groups. Mechanical failure was identified as a major indication for rCDR procedures with an increase over time (p = 0.002). Baseline patient comorbidity burden (p = 0.045) and complication rates (p < 0.001) showed an increase. For both procedures, an increase in outpatient surgeries and procedures performed in rural hospitals was seen (pCDR: p = 0.045; p = 0.006; rCDR: p = 0.028; p = 0.034). Conclusion: PCDR and rCDR procedures significantly increased from 2006 to 2019. At the same time, comorbidity burden and complication rates increased, while procedures were more often performed in an outpatient and rural setting. The identification of these trends can help guide future practice and lead to further areas of research. [ABSTRACT FROM AUTHOR]

Background: Pediatric tibial spine fractures (TSFs) are a well-known clinical entity, but the epidemiology of these injuries is not fully understood. Further, there are limited data on outcomes after TSF treatment, specifically the proportion of patients requiring subsequent anterior cruciate ligament (ACL) reconstruction. Purpose: To describe the distribution of TSF case burden by age and sex and to determine the proportion of patients undergoing subsequent ACL reconstruction or developing ACL insufficiency. Study Design: Descriptive epidemiology study. Methods: The Truven Health MarketScan database was queried to identify patients aged 7 to 18 years with TSFs between 2016 and 2018. Diagnosis and initial treatment (surgical vs nonoperative) were recorded based on database coding. Case burden by age and sex was calculated. The database, which includes longitudinal data, was then queried for subsequent diagnoses of ACL insufficiency as well as subsequent ACL reconstruction procedures performed among the patients. Results: We found 876 cases of TSF, 71.3% of which were treated nonoperatively. The male to female ratio for case burden was 2.2:1. Cases peaked at age 13 to 14 years for boys and age 11 to 12 years for girls. Of all cases identified, 3.7% also had either a diagnosis code for ACL laxity entered in a delayed fashion into the database or a later procedure code for ACL reconstruction (considered together to represent "subsequent ACL insufficiency"). Only 15 subsequent ACL reconstructions (1.7% of cases) were found, all of which were among boys and 9 of which were among boys aged 13 to 14 years. Conclusion: This longitudinal study is the largest epidemiological analysis of pediatric TSFs to date. We found low rates of subsequent ACL insufficiency and ACL reconstruction, with boys aged 13 to 14 years accounting for most of those cases. Rates of subsequent ACL reconstruction were lower than previously reported. Boys accounted for more than two times as many TSF cases as girls. [ABSTRACT FROM AUTHOR]

Background: Hospital-related factors associated with mortality and morbidity after hip fracture surgery are not completely understood. The Veterans Health Administration (VHA) is the largest single-payer, networked healthcare system in the country serving a relatively homogenous patient population with facilities that vary in size and resource availability. These characteristics provide some degree of financial and patient-level controls to explore the association, if any, between surgical volume and facility resource availability and hospital performance regarding postoperative complications after hip fracture surgery.Questions/purposes: (1) Do VHA facilities with the highest complexity level designation (Level 1a) have a disproportionate number of better-than-expected performance outliers for major postoperative complications compared with lower-complexity level facilities? (2) Do VHA facilities with higher hip fracture surgical volume have a disproportionate number of better-than-expected performance outliers for major postoperative complications compared with lower-volume facilities?Methods: We explored the Veterans Affairs Surgical Quality Improvement Project (VASQIP) database from October 2001 to September 2012 for records of hip fracture surgery performed. Data reliability of the VASQIP database has been previously validated. We excluded nine of the 98 VHA facilities for contributing fewer than 30 records. The remaining 89 VHA facilities provided 23,029 records. The VHA designates a complexity level to each facility based on multiple criteria. We labeled facilities with a complexity Level 1a (38 facilities)-the highest achievable VHA designated complexity level-as high complexity; we labeled all other complexity level designations as low complexity (51 facilities). Facility volume was divided into tertiles: high (> 277 hip fracture procedures during the sampling frame), medium (204 to 277 procedures), and low (< 204 procedures). The patient population treated by low-complexity facilities was older, had a higher prevalence of severe chronic obstructive pulmonary disease (26% versus 22%, p < 0.001), and had a higher percentage of patients having surgery within 2 days of hospital admission (83% versus 76%, p < 0.001). High-complexity facilities treated more patients with recent congestive heart failure exacerbation (4% versus 3%, p < 0.001). We defined major postoperative complications as having at least one of the following: death within 30 days of surgery, cardiac arrest requiring cardiopulmonary resuscitation, new q-wave myocardial infarction, deep vein thrombosis and/or pulmonary embolism, ventilator dependence for at least 48 hours after surgery, reintubation for respiratory or cardiac failure, acute renal failure requiring renal replacement therapy, progressive renal insufficiency with a rise in serum creatinine of at least 2 mg/dL from preoperative value, pneumonia, or surgical site infection. We used the observed-to-expected ratio (O/E ratio)-a risk-adjusted metric to classify facility performance-for major postoperative complications to assess the performance of VHA facilities. Outlier facilities with 95% confidence intervals (95% CI) for O/E ratio completely less than 1.0 were labeled "exceed expectation;" those that were completely greater than 1.0 were labeled "below expectation." We compared differences in the distribution of outlier facilities between high and low-complexity facilities, and between high-, medium-, and low-volume facilities using Fisher's exact test.Results: We observed no association between facility complexity level and the distribution of outlier facilities (high-complexity: 5% exceeded expectation, 5% below expectation; low-complexity: 8% exceeded expectation, 2% below expectation; p = 0.742). Compared with high-complexity facilities, the adjusted odds ratio for major postoperative complications for low-complexity facilities was 0.85 (95% CI, 0.67-1.09; p = 0.108).We observed no association between facility volume and the distribution of outlier facilities: 3% exceeded expectation and 3% below expectation for high-volume; 10% exceeded expectation and 3% below expectation for medium-volume; and 7% exceeded expectation and 3% below expectation for low-volume; p = 0.890). The adjusted odds ratios for major postoperative complications were 0.87 (95% CI, 0.73-1.05) for low- versus high-volume facilities and 0.89 (95% CI, 0.79-1.02] for medium- versus high-volume facilities (p = 0.155).Conclusions: These results do not support restricting facilities from treating hip fracture patients based on historical surgical volume or facility resource availability. Identification of consistent performance outliers may help health care organizations with multiple facilities determine allocation of services and identify characteristics and processes that determine outlier status in the interest of continued quality improvement.Level Of Evidence: Level III, therapeutic study.

Background: The opioid epidemic is one of the most pressing public health crises in the USA. With fractures being amongst the most common reasons for a child to require surgical intervention and receive post-surgical pain management, characterisation of opioid prescription patterns and risk factors is critical. We hypothesised that the numbers of paediatric patients receiving opioids, or who developed persistent opioid use, are significant, and a number of risk factors for persistent opioid use could be identified.Methods: We conducted a retrospective population-based cohort study. National claims data from the Truven Health Analytics® MarketScan database were used to (i) characterise opioid prescription patterns and (ii) describe the epidemiology and risk factors for single use and persistent use of opioids amongst paediatric patients who underwent surgical intervention for fracture treatment.Results: Amongst 303 335 patients, 21.5% received at least one opioid prescription within 6 months after surgery, and 1671 (0.6%) developed persistent opioid use. Risk factors for persistent opioid use include older age; female sex; lower extremity trauma; surgeries involving the spine, rib cage, or head; closed fracture treatment; earlier surgery years; previous use of opioid; and higher comorbidity burden.Conclusions: Amongst a cohort of paediatric patients who underwent surgical fracture treatment, 21.5% filled at least one opioid prescription, and 0.6% (N=1671) filled at least one more opioid prescription between 3 and 6 months after surgery. Understanding risk factors related to persistent opioid use can help clinicians devise strategies to counter the development of persistent opioid use for paediatric patients. [ABSTRACT FROM AUTHOR]

Study Design: Retrospective database study.Objective: We sought to identify trends in demographics, comorbidities, and postoperative complications among patients undergoing ACDF and PLF.Summary Of Background Data: As demand for anterior cervical discectomy and fusion (ACDF) and posterior lumbar fusion (PLF) surgery continues to increase, it is important to understand changes in the healthcare system and patient populations undergoing these procedures.Methods: We identified 220,520 ACDF and 151,547 PLF surgeries (2006-2016; Premier Healthcare database). Annual proportions or medians were calculated for patient and hospital characteristics, and (Elixhauser) comorbidities. Postoperative complications, including blood transfusions, cardiovascular, pulmonary, renal, or wound complications, hemorrhage, stroke, sepsis, thromboembolism, delirium, inpatient falls, and mortality, were reported per 1000 inpatient days. Trends were assessed by Cochran-Armitage tests and linear regression for binary and continuous variables, respectively.Results: The median age of patients undergoing ACDF and PLF increased significantly from 2006 to 2016 (50 to 57 yr and 58 to 61 yr, respectively; P < 0.001) coinciding with an increasing comorbidity burden (30.2% to 47.9% and 44.9% to 55.7%, respectively representing the share of patients with ≥2 Elixhauser comorbidities; P < 0.001). Overall rate of any complication experienced a significant decline after both ACDF (24.5 to 20.8 per 1000 inpatient days; P = 0.002) and PLF (30.5 to 23.1 per 1000 inpatient days; P < 0.001).Conclusions: The comorbidity burden of patients undergoing ACDF and PLF increased substantially from 2006 to 2016, however without a corresponding increase in overall complication rate. Understanding these changes can help guide future practice, advise in the allocation of resources, and inform future areas of research.Level Of Evidence: 3. [ABSTRACT FROM AUTHOR]

Study Design: Retrospective database study.Objective: We sought to investigate trends and risk factors for new-onset anxiety and/or depression within 6 months after elective spine surgery.Summary Of Background Data: Surgery represents a stressful experience associated with a number of physiological and psychological consequences. A subset of patients develop clinically significant symptoms of new-onset anxiety or depression. However, the incidence of and risk factors for these adverse outcomes after spine surgery remain ill-defined.Methods: We performed a retrospective analysis including anterior cervical discectomy and fusion and posterior lumbar fusion cases from 2012 to 2015, utilizing the Truven MarketScan database. Primary outcomes were new-onset depression, new-onset anxiety, and new-onset depression and/or anxiety after surgery. Potential risk factors included patient demographics, comorbidities, hospital and procedural characteristics as well as perioperative opioid regimens. Multivariable logistic regression models measured associations between risk factors and outcomes. Odds ratios (OR) were reported and results with P < 0.0167 were considered statistically significant.Results: Among 39,495 unique patients, overall incidence of new-onset depression and anxiety was 6% and 11.2%, respectively. In adjusted analyses, significant risk factors across all three outcomes included chronic opioid use (ORs ranging from 1.31 to 2.93; P < 0.01), female sex (ORs ranging from 1.25 to 1.67; P < 0.01), longer length of stay (ORs ranging from 1.05 to 1.08; P < 0.01), and readmission within 6 months of surgery (OR ranging from 1.31 to 1.68; P < 0.01).Conclusion: We identified several risk factors contributing to increased odds of new-onset depression and/or anxiety after spine fusion surgery. These data may aid the implementation of preventative measures among identified high-risk patients.Level Of Evidence: 3. [ABSTRACT FROM AUTHOR]

Background: The value of intravenous acetaminophen in postoperative pain management remains debated. The authors tested the hypothesis that intravenous acetaminophen use, in isolation and in comparison to oral, would be associated with decreased opioid utilization (clinically significant reduction defined as 25%) and opioid-related adverse effects in open colectomy patients.Methods: Using national claims data from open colectomy patients (Premier Healthcare Database, Premier Healthcare Solutions, Inc., USA; 2011 to 2016; n = 181,640; 602 hospitals), we separately categorized oral and intravenous acetaminophen use: 1 (1,000 mg) or more than 1 dose on the day of surgery, postoperative day 1, or later. Multilevel models measured associations between intravenous or oral acetaminophen and (1) opioid utilization and (2) opioid-related adverse effects. Percent change and multiplicity-adjusted 99.5% CI are reported.Results: Overall, 25.1% of patients received intravenous acetaminophen, of whom 48.0% (n = 21,878) received 1 dose on the day of surgery. In adjusted analyses, particularly more than 1 dose of intravenous acetaminophen (versus nonuse) on postoperative day 1 was associated with a -12.4% (99.5% CI, -15.2 to -9.4%) change in opioid utilization. In comparison, a stronger reduction was seen in those receiving more than 1 oral acetaminophen dose: -22.6% (99.5% CI, -26.2 to -18.9%). Unadjusted group medians were 550 and 490 oral morphine equivalents, respectively. Intravenous versus oral differences were less pronounced among those receiving more than 1 acetaminophen dose on the day of surgery: -8.0% (99.5% CI, -11.0 to -4.9%) median 499 oral morphine equivalents versus -8.7% (99.5% CI, -14.4 to -2.7%) median 445 oral morphine equivalents, respectively; all statistically significant, but none clinically significant. Comparable outcome patterns existed for opioid-related adverse effects.Conclusions: The demonstrated marginal effects do not support routine use of intravenous acetaminophen given alternative nonopioid analgesic options.

Study Objective: The objective was to analyze the impact of a peripheral nerve block in addition to general anesthesia on hospital admission after surgical rotator cuff repair.Design: This was a population-based outcome study. The cost effectiveness of ambulatory rotator cuff repair relies on the discharge of patients on the day of surgery. As the impact of a peripheral nerve block in addition to general anesthesia on this outcome is unknown, we sought to elucidate this subject using population-based data.Patients and Methods: Information on patients undergoing rotator cuff surgery under general anesthesia with or without the addition of a peripheral nerve block (GN vs G) from a retrospective database provided by Premier Perspective, Inc, Charlotte, NC (http://www.premierinc.com), was analyzed. Using multilevel multivariable regressions, we evaluated the independent impact of the type of anesthesia on the outcomes hospital admission, combined major complications, and increased hospital costs.Results: We identified 27,201 patients who underwent surgical rotator cuff repair. Approximately 89% (24,240) of patients were discharged on the day of surgery, whereas 11% (2961) were admitted to the hospital. The admission rates for the GN group were 9.1% and 11.2% for the G group (P=.0001). The multivariable regression models showed that patients with the addition of a peripheral nerve block had 18% less risk of being admitted to the hospital (relative risk [RR]=0.82; 95% confidence interval [CI], 0.74-0.91; P=.0003) compared with those without this intervention. Differences in risk for combined major complications (RR=1.00; 95% CI, 0.83-1.20; P=.9751) or increased hospital costs (RR=0.97; 95% CI, 0.93-1.02; P=.2538) were nonsignificant.Discussion: For patients undergoing surgical rotator cuff repair under general anesthesia, the addition of a peripheral nerve block may be associated with a reduction in the need for postoperative hospital admission after ambulatory surgery. Although the reason for this finding has to remain speculative, better pain control may play a role. [ABSTRACT FROM AUTHOR]
