RESUMO
Purpose: The indications for prophylactic antibiotics in hand surgery remain undefined. Current literature has focused solely on readmission and reoperation for surgical site infection, while neglecting minor infectious complications treated at outpatient follow-up in addition to complications from antibiotic therapy observed after surgery. This study sought to analyze major and minor infection rates, as well as adverse effects of preoperative antibiotics after clean hand surgery. Methods: A prospective cohort study was conducted over a 6-month period. The cohorts included patients who received preoperative antibiotic prophylaxis and those that did not. Patient details and operative data were obtained during the first postoperative visit following the index surgery. Primary outcomes assessed were as follows: (1) major infection, defined as admission or reoperation for infection; (2) minor infection, defined as use of postoperative oral antibiotics; and (3) complications of antibiotic therapy. Results: A total of 377 consecutive patients underwent operations of the upper extremity. Complications from preoperative antibiotic therapy were seen in 6.9% of patients. Overall, there were no major postoperative infections and the minor postoperative infection rate was 5.6%. The minor infection rate was 6.9% (9/131) among patients who did not receive preoperative antibiotics and 4.9% (12/246) among patients who received preoperative antibiotics (P = .57). Conclusions: A 5.6% minor infection rate was identified following clean hand surgery, with no cases of major infection. Preoperative antibiotics did not demonstrate benefit in terms of reduction of minor infections, but they did yield a 6.9% adverse reaction rate, including one case of Clostridium difficile infection warranting hospitalization. Caution is recommended while prescribing prophylactic antibiotics for clean hand surgeries, given the lack of clear benefits and the potential for adverse effects. Type of Study/level of evidence: Prognostic II.
RESUMO
Background Purpose: Patient satisfaction has become an increasingly important component of quality measures for both hospital reimbursement and quality assessment. Additionally, patient satisfaction influences patient behavior and patient follow-up. The purpose of this study was to identify preoperative factors associated with patient satisfaction 2 years after shoulder surgery. Methods: Electronic surveys were used to collect patient information including demographic, surgical, and social history, as well as outcome data. Satisfaction was measured 2 years after surgery using the Surgical Satisfaction Questionnaire. Results: Multivariable linear regression identified preoperative Patient-Reported Outcomes Measurement Information System Pain Interference, annual income, and American Society of Anesthesiologists score as independent predictors of lower patient satisfaction, while total shoulder arthroplasty was an independent predictor of greater patient satisfaction. The model accounted for 15% of the variance in satisfaction scores (R2 = 0.15). Conclusion: Patient satisfaction 2 years after shoulder surgery is associated with preoperative patient-reported outcome scores. Lower patient satisfaction is independently predicted by greater preoperative PROMIS PI, income less than $70,000, and ASA score >1, while higher patient satisfaction is predicted by total shoulder arthroplasty.
RESUMO
Chondrosarcomas are rare tumors and, historically, investigation of these tumors has been limited to small series and single-institution studies. There have been no studies that evaluated the identification or comparison of differences in prognostic factors between the five known non-conventional chondrosarcoma subtypes (myxoid, juxtacortical, clear-cell, mesenchymal, and dedifferentiated). The purpose of this paper was to determine the demographic, clinical, incidence, and tumor characteristics of all five known non-conventional chondrosarcoma subtypes, determine the 1-, 5-year, and median survival differences between these subtypes, and to determine the demographic and clinical variables that are significant prognostic indicators for each chondrosarcoma subtypes. We retrospectively reviewed the SEER database for all patients with non-conventional chondrosarcoma. χ2 testing was used for correlations between clinical variables. Kaplan-Meier and Cox proportional hazard analysis were used to compare survival of the subtypes, and to assess the prognostic value of age group, race, sex, grade, anatomic location, and metastatic involvement. Several demographic characteristics including gender, race, age, and grade varied between chondrosarcoma subtypes. The tumor characteristics showed marked differences in presence of metastasis on presentation between the subtypes with increasing order of rate of metastasis with juxtacortical (2.1%), clear cell (5.7%), myxoid (7.6%), mesenchymal (10.6%), and the highest in dedifferentiated (19.8%). One-, 5-year, and median survival differed significantly between chondrosarcomas subtypes. The highest median survival was found in the juxtacortical subtype (97 months), followed by clear cell (79 months), myxoid (60 months), mesenchymal (33.5 months), and lowest in dedifferentiated (11 months). The only prognostic variable that was shown to significantly impact the survival of each non-conventional chondrosarcoma subtype was a metastatic disease at diagnosis (p = 0.03 to p < 0.001). Subtyping classification of chondrosarcoma should be made whenever possible, given differences in survival and prognostic factors between chondrosarcoma subtypes. © 2019 Orthopaedic Research Society.
