RESUMO
CONTEXT: The single-legged-squat test (SLST) and step-down test (SDT) are 2 functional performance tests commonly used to evaluate active people with nonarthritic hip pain and dysfunction. However, evidence to support the use of the SLST and SDT in this population is lacking. OBJECTIVE: To offer evidence of reliability and validity for the SLST and SDT in evaluating patients with nonarthritic hip pain. DESIGN: Cross-sectional study. SETTING: Orthopaedic surgeon's clinical office. PATIENTS OR OTHER PARTICIPANTS: Forty-five patients (27 female and 18 male participants; age = 28.5 ± 10 years, height = 171.6 ± 10.1 cm, weight = 73.9 ± 15.2 kg, and body mass index = 25 ± 4.1) diagnosed with nonarthritic hip pain. MAIN OUTCOME MEASURE(S): Participants performed the SLST and SDT. Interrater reliability and validity of passive internal rotation of the hip, visual analog scale (VAS) scores, and hip outcome scores (HOSs) for limitations in activities of daily living and sport-related activities (SRAs) were collected. RESULTS: Interrater reliability was moderate to excellent for both the SLST (0.603-0.939) and SDT (0.745-0.943). Participants who passed or failed the SLST and SDT differed on the following measures: VAS for the SLST (F1,43 = 16.21, P < .001); VAS for the SDT (F1,43 = 13.41, P = .001); HOS-activities of daily living for the SLST (F1,40 = 5.15, P = .029); HOS-SRAs for the SLST (F1,40 = 7.48, P = .009); and HOS-SRAs for the SDT (F1,40 = 6.42, P = .015). CONCLUSIONS: Our study offers evidence for the use of the SLST and SDT as reliable and valid functional performance tests in the evaluation of physical function for patients with nonarthritic hip pain.

OBJECTIVE: To determine the clinical utility of hemoglobin level testing in guiding postoperative care following total laparoscopic hysterectomies performed for benign indications. STUDY DESIGN: Retrospective cohort study. RESULTS: A total of 629 women underwent total laparoscopic hysterectomies during the 24 month study period. Only 16 (2.5%) developed symptoms and/or signs suggestive of hemodynamic compromise. When compared to asymptomatic patients, symptomatic patients had a larger decrease in postoperative hemoglobin level (2.66 vs 1.80g/dL, P = .007) and were more likely to undergo blood transfusion, pelvic imaging or reoperation (P < .001). Women with a smaller body mass index and/or higher intraoperative intravenous fluid volume were more likely to have a larger decrease in postoperative hemoglobin level (P < .05). Past surgical history, duration and complexity of the hysterectomy, estimated surgical blood loss, uterine weight, and perioperative use of intravenous ketorolac were not associated with a greater decrease in postoperative hemoglobin (P > .05). Using the University of Pittsburgh Medical Center's annual laparoscopic hysterectomy rate and insurance companies' reimbursement for blood hemoglobin testing, we estimated the national annual cost for hemoglobin testing following total laparoscopic hysterectomy to be $2,804,662. CONCLUSION: Hemoglobin level testing has little clinical benefit following elective total laparoscopic hysterectomy and should be reserved for patients who develop signs or symptoms suggestive of acute anemia. Heath care cost savings can be substantial if this test is no longer routinely requested following total laparoscopic hysterectomies.
