The Associations of Hospital Volume, Surgeon Volume, and Surgeon Experience with Complications and 30-Day Rehospitalization after Free Tissue Transfer: A National Population Study.

ABSTRACT: Greater provider volume is associated with better outcomes. There is, however, a paucity of evidence on volume-outcome associations for surgical complications and 30-day all-cause rehospitalization after free tissue transfer or free flap surgery. Surgical complications and frequent rehospitalization are important quality indicators that substantially hinder appropriate health care spending. The authors hypothesized that increased provider volume and surgeon experience are associated with lower complication and hospital readmission rates.The authors conducted a retrospective cohort study of adults aged 18 to 64 years who underwent free tissue transfer. They examined 100 percent of all free tissue transfers between 2001 and 2012 using Taiwan's national data, and used regression modeling to examine associations between volume and outcome. All models were adjusted for patient, surgeon, and hospital characteristics.Seventeen percent of free tissue transfer operations (4201 of 25,327) had complications. Infection was the most prevalent after free tissue transfer (70 percent), and the 30-day rehospitalization rate was approximately 20 percent. Hospital volume was associated with a small decrease in complications (OR, 0.99; 95 percent CI, 0.99 to 0.99; p < 0.01). For surgeons, years of experience and not annual case volume decreased surgical complications (OR, 0.98; 95 percent CI, 0.97 to 0.99; p = 0.01). The authors did not find any association between hospital or surgeon volume, or surgeon's years of experience and 30-day rehospitalization.Higher-volume hospitals and more experienced surgeons were shown to have a lower likelihood of postsurgery complications. Hospital process and structure affect outcomes and reduce surgical complications. Reducing 30-day rehospitalization may require payment reform, as it demands coordinated care before and after hospital discharge.Therapeutic, III.

Project description:BackgroundTibial shaft fractures are the most common long-bone injury, with a reported annual incidence of more than 75 000 in the United States. This study aimed to determine whether patients with tibial fractures managed with intramedullary nails experience a lower rate of reoperation if treated at higher-volume hospitals, or by higher-volume or more experienced surgeons.MethodsThe Study to Prospectively Evaluate Reamed Intramedullary Nails in Patients with Tibial Fractures (SPRINT) was a multicentre randomized clinical trial comparing reamed and nonreamed intramedullary nailing on rates of reoperation to promote fracture union, treat infection or preserve the limb in patients with open and closed fractures of the tibial shaft. Using data from SPRINT, we quantified centre and surgeon volumes into quintiles. We performed analyses adjusted for type of fracture (open v. closed), type of injury (isolated v. multitrauma), gender and age for the primary outcome of reoperation using multivariable logistic regression.ResultsThere were no significant differences in the odds of reoperation between high- and low-volume centres (p = 0.9). Overall, surgeon volume significantly affected the odds of reoperation (p = 0.03). The odds of reoperation among patients treated by moderate-volume surgeons were 50% less than those among patients treated by verylow-volume surgeons (odds ratio [OR] 0.50, 95% confidence interval [CI] 0.28–0.88), and the odds of reoperation among patients treated by high-volume surgeons were 47% less than those among patients treated by very-low-volume surgeons (OR 0.53, 95% CI 0.30–0.93).ConclusionThere appears to be no significant additional patient benefit in treatment by a higher-volume centre for intramedullary fixation of tibial shaft fractures. Additional research on the effects of surgical and clinical site volume in tibial shaft fracture management is needed to confirm this finding. The odds of reoperation were higher in patients treated by very-low-volume surgeons; this finding may be used to optimize the results of tibial shaft fracture management.

Project description:The association between hospital volume and the death rate for patients who are hospitalized for acute myocardial infarction, heart failure, or pneumonia remains unclear. It is also not known whether a volume threshold for such an association exists.We conducted cross-sectional analyses of data from Medicare administrative claims for all fee-for-service beneficiaries who were hospitalized between 2004 and 2006 in acute care hospitals in the United States for acute myocardial infarction, heart failure, or pneumonia. Using hierarchical logistic-regression models for each condition, we estimated the change in the odds of death within 30 days associated with an increase of 100 patients in the annual hospital volume. Analyses were adjusted for patients' risk factors and hospital characteristics. Bootstrapping procedures were used to estimate 95% confidence intervals to identify the condition-specific volume thresholds above which an increased volume was not associated with reduced mortality.There were 734,972 hospitalizations for acute myocardial infarction in 4128 hospitals, 1,324,287 for heart failure in 4679 hospitals, and 1,418,252 for pneumonia in 4673 hospitals. An increased hospital volume was associated with reduced 30-day mortality for all conditions (P<0.001 for all comparisons). For each condition, the association between volume and outcome was attenuated as the hospital's volume increased. For acute myocardial infarction, once the annual volume reached 610 patients (95% confidence interval [CI], 539 to 679), an increase in the hospital volume by 100 patients was no longer significantly associated with reduced odds of death. The volume threshold was 500 patients (95% CI, 433 to 566) for heart failure and 210 patients (95% CI, 142 to 284) for pneumonia.Admission to higher-volume hospitals was associated with a reduction in mortality for acute myocardial infarction, heart failure, and pneumonia, although there was a volume threshold above which an increased condition-specific hospital volume was no longer significantly associated with reduced mortality.

Project description:Rehospitalizations within 30 days of discharge are responsible for a large portion of healthcare spending. One approach to preventing rehospitalizations is early follow-up, usually defined as an office visit with a primary care physician within 7 days of discharge--an approach that is being incentivized by health plans. However, evidence regarding its effectiveness is limited.We aimed to determine whether an office visit with a primary care physician within 7 days after discharge is associated with 30-day rehospitalization.This was an observational study set within a randomized trial.The study included patients age 65 and older receiving care from a multi-specialty group practice and discharged from hospital to home between 26 August 2010 and 25 August 2011. To control for confounding, we identified characteristics of patients and hospital stays that are predictive of rehospitalization, and also developed high-dimensional propensity scores. Analyses used Cox proportional hazards models and took into account varying amounts of opportunity time for office visits.We looked at 30-day rehospitalizations at any hospital.Of 3,661 patients discharged to home during the study year, 707 (19.3%) were rehospitalized within 30 days. Patients receiving an office visit within 7 days numbered 1,808 (49.4%), and of these, 1,000 (27.3%) were with a primary care physician. In models predicting rehospitalization, stratified on deciles of propensity score and controlling for additional confounders, the hazard ratios associated with office visits with a primary care physician within 7 days were 0.98 (95% CI 0.80, 1.21); for visits with any physician, the hazard ratio was HR 1.04, (95% CI 0.87, 1.25).We found no protective effect for office visits within 7 days. Such visits may need to be specifically focused on a range of issues related to the specific reasons why patients are rehospitalized. It is likely that outpatient visits will need to be set within comprehensive transition programs.
