OBJECTIVES: Previous studies have identified predictors of prolonged length of stay (LOS) following pulmonary lobectomy. LOS is typically described to have a direct relationship to postoperative complications. We sought to determine the LOS and factors associated with variability after uncomplicated pulmonary lobectomy. METHODS: Analysing the State Inpatient Databases, Healthcare Cost and Utilization Project, Agency for Healthcare Research and Quality database, we reviewed lobectomies performed (2009-11) on patients in California, Florida and New York. LOS and comorbidities were identified. Multivariable regression analysis (MVA) was used to determine factors associated with LOS greater than the median. Patients with postoperative complications or death were excluded. RESULTS: Among 22 647 lobectomies performed, we identified 13 099 patients (58%) with uncomplicated postoperative courses (mean age = 66 years; 56% female; 76% white, 57% Medicare; median DEYO comorbidity score = 3, 55% thoracotomy, 45% thoracoscopy/robotic). There was a wide distribution in LOS [median LOS = 5 days; interquartile range (IQR) 4-7]. ByMVA, predictors of prolonged LOS included, age ≥75 years [odds ratio (OR) 1.7, 95% confidence interval (CI) 1.4-2.0], male gender (OR 1.2, 95% CI 1.1-1.2), chronic obstructive pulmonary disease (OR 1.6, 95% CI 1.5-1.7) and other comorbidities, Medicaid payer (OR 1.7, 95% CI 1.4-2.1) versus private insurance, thoracotomy (OR 3.0, 95% CI 2.8-3.3) versus video-assisted thoracoscopic surgery/robotic approach and low hospital volume (OR 2.4, 95% CI 2.1-2.6). CONCLUSIONS: Variability exists in LOS following even uncomplicated pulmonary lobectomy. Variability is driven by clinical factors such as age, gender, payer and comorbidities, but also by surgical approach and volume. All of these factors should be taken into account when designing clinical care pathways or when allocating payment resources. Attempts to define an optimal LOS depend heavily upon the patient population studied. [ABSTRACT FROM AUTHOR]

Abstract: Background context: Despite increasing utilization of surgical spine fusions, a paucity of literature addressing perioperative complications after revision posterior spinal fusion (RPSF) versus primary posterior spine fusion (PPSF) of the thoracic and lumbar spine exists. Purpose: To examine demographics of patients undergoing PPSF and RPSF of the thoracic and lumbar spine, assess the incidence of perioperative morbidity and mortality, and determine independent risk factors for in-hospital death. Study design/setting: Analysis of nationally representative data collected for the National Inpatient Sample (NIS). Patient sample: All discharges included in the NIS with a procedure code for posterior thoracic and lumbar spine fusion from 1998 to 2006. Outcome measures: In-hospital mortality and morbidity. Methods: Data collected for each year between 1998 and 2006 for the NIS were analyzed. Discharges with a procedure code for thoracic and lumbar spine fusion were included in the sample. The prevalence of patient- as well as health care–related demographics was evaluated by procedure type (primary vs. revision). Frequencies of procedure-related complications and in-hospital mortality were analyzed. Independent predictors for in-hospital mortality were determined. Results: We identified 222,549 PPSF and 12,474 RPSF discharges between 1998 and 2006. Patients undergoing PPSF were significantly younger (51.23 years; confidence interval [CI]=51.16, 51.31) and had lower average comorbidity indices (0.40; CI=0.39, 0.41) than those undergoing RPSF (52.69 years; CI=52.43, 52.97) and (0.44; CI=0.43, 0.45), p<.0001. The incidence of procedure-related complications was 16.02% among RPSF compared with 13.44% in PPSF patients (p<.0001). In-hospital mortality rates after PPSF were approximately twice those of RPSF (0.28% vs. 0.15%, p=.006). Adjusted risk factors for increased in-hospital mortality included PPSF compared with RPSF, male gender, and increasing age. A number of comorbidities, complications, and specific surgical indications increased the risk for perioperative death. Conclusion: Despite being performed in generally younger and healthier patients and having lower perioperative morbidity, PPSF procedures are associated with increased mortality compared with RPSF procedures. The findings of this study can be used for risk stratification, accurate patient consultation, and hypothesis formation for future research. [Copyright &y& Elsevier]

Study Objective: To confirm the relationship between primary payer status as a predictor of increased perioperative risks and post-operative outcomes after total hip replacements.Design: Retrospective cohort study.Setting: Administrative database study using 2007-2011 data from California, Florida, and New York from the State Inpatient Databases (SID), Healthcare Cost and Utilization Project, Agency for Healthcare Research and Quality.Patients: 295,572 patients age≥18years old who underwent total hip replacement with non-missing insurance data were collected, using International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) diagnoses and procedures code (ICD-9-CM code 81.51).Interventions: Patients underwent total hip replacement.Measurements: Patients were cohorted by insurance type as either Medicare, Medicaid, Uninsured, Other, and Private Insurance. Demographic characteristics and comorbidities were compared. Unadjusted rates of in-hospital mortality, postoperative complications, LOS, 30-day, and 90-day readmission status were compared. Adjusted odds ratios were calculated for our outcomes using multivariate linear and logistic regression models fitted to our data.Main Results: Medicaid patients incurred a 125% increase in the odds of in-hospital mortality compared to those with Private Insurance (OR 2.25, 99% CI 1.01-5.01). Medicaid payer status was associated with the highest statistically significant adjusted odds of mortality, any complication (OR, 1.26), cardiovascular complications (OR, 1.37), and infectious complications (OR, 1.66) when compared with Private Insurance. Medicaid patients had the highest statistically significant adjusted odds of 30-day (OR, 1.63) and 90-day readmission (OR, 1.58) and the longest adjusted LOS.Conclusions: We found higher unadjusted rates and risk adjusted odds ratios of postoperative mortality, morbidity, LOS, and readmissions for patients with Medicaid insurance as compared to patients with Private Insurance. Our study shows that primary payer status serves as a predictor of perioperative risks and that primary payer status should be viewed as a peri-operative risk factor. [ABSTRACT FROM AUTHOR]

Study Design: Analysis of population-based national hospital discharge data collected for the National Inpatient Sample.Objective: To examine demographics of patients undergoing primary anterior spine fusion (ASF), posterior spine fusion (PSF), and anterior/posterior spine fusion (APSF) of the noncervical spine, assess the incidence of perioperative morbidity and mortality, and determine independent risk factors for in-hospital death.Summary Of Background Data: The utilization of surgical fusion has been increasing dramatically. Despite this trend, a paucity of literature addressing perioperative outcomes exists.Methods: Data collected for each year between 1998 and 2006 for the National Inpatient Sample were analyzed. Discharges with a procedure code for primary noncervical spine fusion were included in the sample. The prevalence of patient as well as health care system-related demographics were evaluated by procedure type (ASF, PSF, and APSF). Frequencies of procedure-related complications and in-hospital mortality were analyzed. Independent predictors for in-hospital mortality were determined.Results: We identified 261,256 entries representing an estimated 1,273,228 hospitalizations for primary spine fusion. Patients undergoing ASF and APSF were significantly younger (44.8 ± 0.08 and 44.22 ± 0.11 years) and had lower average comorbidity indeces (0.30 ± 0.002 and 0.31 ± 0.004) than those undergoing PSF (52.12 ± 0.04 years and 0.41 ± 0.002) (P < 0.0001). The incidence of procedure-related complications was 18.68% among ASF, 15.72% in PSF, and 23.81% in APSF patients (P < 0.0001). In-hospital mortality rates after APSF were approximately twice those of PSF (0.51 ± 0.038 vs. 0.26 ± 0.012) (P < 0.0001). Adjusted risk factors for in-hospital mortality included the following: APSF and ASF compared to PSF, male gender, increasing age, and increasing comorbidity burden. Several comorbidities and complications independently increased the risk for perioperative death, as did underlying spinal pathology.Conclusion: Despite being performed in generally younger and healthier patients, APSF and ASF are associated with increased morbidity and mortality. Our findings can be used for the purposes of risk stratification, accurate patient consultation, and hypothesis formation for future research. [ABSTRACT FROM AUTHOR]

The article discusses a study to examine the various results in patient health with regards to the treatment of anterior cervical spine fusions. It states that anterior cervical decompression and spine fusion (ACDF) is a common procedure, but that little information about related health effects are available. The study analyzed information between 1990 to 2004 from the National Hospital Discharge Survey, choosing 771,932 records. A list of conditions resulting from the procedure is presented, based on age and other factors.

The article features the study that aims to determine the difference in perioperative outcomes between unilateral total knee arthroplasties (UTKAs) and bilateral total knee arthroplasties (BTKAs) in the U.S. The study analyzes the data from Nationwide Inpatient Sample from 1998 to 2006. Researchers separated data on BTKAs, healthcare-system related and patient demographics, and the incidence of procedure-related complication and in-hospital mortality. The study concludes that BTKAs are more risky compared to UTKAs while BTKAs caused patients to increase their morbidity.
