    Absence of July Phenomenon in Acute Ischemic Stroke Care Quality and Outcomes.
    (Journal of the American Heart Association, 2018-01-31) Gonzalez-Castellon, Marco; Ju, Christine; Xian, Ying; Hernandez, Adrian; Fonarow, Gregg C; Schwamm, Lee; Smith, Eric E; Bhatt, Deepak L; Reeves, Matthew; Willey, Joshua Z
    BACKGROUND:Lower care quality and an increase in adverse outcomes as a result of new medical trainees is a concept well rooted in popular belief, termed the "July phenomenon." Whether this phenomenon occurs in acute ischemic stroke has not been well studied. METHODS AND RESULTS:We analyzed data from patients admitted with ischemic stroke in 1625 hospitals participating in the Get With The Guidelines-Stroke program for the 5-year period between January 2009 and December 2013. We compared acute stroke treatment processes and in-hospitals outcomes among the 4 quarters (first quarter: July-September, last quarter: April-June) of the academic year. Multivariable logistic regression models were used to evaluate the relationship between academic year transition and processes measures. A total of 967 891 patients were included in the study. There was a statistically significant, but modest (<4 minutes or 5 percentage points) difference in distribution of or quality and clinical metrics including door-to-computerized tomography time, door-to-needle time, the proportion of patients with symptomatic intracranial hemorrhage within 36 hours of admission, and the proportion of patients who received defect-free care in stroke performance measures among academic year quarters (P<0.0001). In multivariable analyses, there was no evidence that quarter 1 of the academic year was associated with lower quality of care or worse in-hospital outcomes in teaching and nonteaching hospitals. CONCLUSIONS:We found no evidence of the "July phenomenon" in patients with acute ischemic stroke among hospitals participating in the Get With The Guidelines-Stroke program.

    Effects of teaching on hospital costs.
    (J Health Econ, 1983-03) Sloan, FA; Feldman, RD; Steinwald, AB
    This study estimates effects of undergraduate and graduate medical education on hospital costs, using a national sample of 367 U.S. community hospitals observed in 1974 and 1977. Data on other cost determinants, such as casemix, allow us to isolate the influence of teaching with greater precision than most previous studies. Non-physician expense in major teaching hospitals is at most 20 percent higher than in non-teaching hospitals; the teaching effect is about half this for hospitals with more limited teaching programs. Results for ancillary service departments are consistent with those for the hospital as a whole.

    Surgical Team Stability and Risk of Sharps-Related Blood and Body Fluid Exposures During Surgical Procedures.
    (Infection control and hospital epidemiology, 2016-05) Myers, Douglas J; Lipscomb, Hester J; Epling, Carol; Hunt, Debra; Richardson, William; Smith-Lovin, Lynn; Dement, John M

    Objective

    To explore whether surgical teams with greater stability among their members (ie, members have worked together more in the past) experience lower rates of sharps-related percutaneous blood and body fluid exposures (BBFE) during surgical procedures.

    Design

    A 10-year retrospective cohort study.

    Setting

    A single large academic teaching hospital.

    Participants

    Surgical teams participating in surgical procedures (n=333,073) performed during 2001-2010 and 2,113 reported percutaneous BBFE were analyzed.

    Methods

    A social network measure (referred to as the team stability index) was used to quantify the extent to which surgical team members worked together in the previous 6 months. Poisson regression was used to examine the effect of team stability on the risk of BBFE while controlling for procedure characteristics and accounting for procedure duration. Separate regression models were generated for percutaneous BBFE involving suture needles and those involving other surgical devices. RESULTS The team stability index was associated with the risk of percutaneous BBFE (adjusted rate ratio, 0.93 [95% CI, 0.88-0.97]). However, the association was stronger for percutaneous BBFE involving devices other than suture needles (adjusted rate ratio, 0.92 [95% CI, 0.85-0.99]) than for exposures involving suture needles (0.96 [0.88-1.04]).

    Conclusions

    Greater team stability may reduce the risk of percutaneous BBFE during surgical procedures, particularly for exposures involving devices other than suture needles. Additional research should be conducted on the basis of primary data gathered specifically to measure qualities of relationships among surgical team personnel.

    The risk of risk-adjustment measures for perioperative spine infection after spinal surgery.
    (Spine, 2011-04) Goode, Adam P; Cook, Chad; Gill, J Brian; Tackett, Sean; Brown, Christopher; Richardson, William

    Study design

    Cross-sectional data analysis of the Nationwide Inpatient Sample (NIS).

    Objective

    To develop a risk-adjustment index specific for perioperative spine infection and compare this specific index to the Deyo Comorbidity Index. Assess specific mortality and morbidity adjustments between teaching and nonteaching facilities.

    Summary of background data

    Risk-adjustment measures have been developed specifically for mortality and may not be sensitive enough to adjust for morbidity across all diagnosis.

    Methods

    This condition-specific index was developed by using the NIS in a two-step process to determine confounders and weighting. Crude and adjusted point estimates for the Deyo and condition-specific index were compared for routine discharge, death, length of stay, and total hospital charges and then stratified by teaching hospital status.

    Results

    A total of 23,846 perioperative spinal infection events occurred in the NIS database between 1988 and 2007 of 1,212,241 procedures. Twenty-three diagnoses made up this condition-specific index. Significant differences between the Deyo and the condition-specific index were seen among total charges and length of stay at nonteaching hospitals (P < 0.001) and death, length of stay, and total charges (P < 0.001) for teaching hospitals.

    Conclusion

    This study demonstrates several key points. One, condition-specific measures may be useful when morbidity is of question. Two, a condition-specific perioperative spine infection adjustment index appears to be more sensitive at adjusting for comorbidities. Finally, there are inherent differences in hospital disposition characteristics for perioperative spine infection across teaching and nonteaching hospitals even after adjustment.
