Do Changes in Hospital Outpatient Payments Affect the Setting of Care?
Objective
To examine whether decreases in Medicare outpatient payment rates under the Outpatient Prospective Payment System (OPPS) caused outpatient care to shift toward the inpatient setting. Data Sources/Study Setting
Hospital inpatient and outpatient discharge files from the Florida Agency for Health Care Administration from 1997 through 2008. Study Design
This study focuses on inguinal hernia repair surgery, one of the most commonly performed surgical procedures in the United States. We estimate multivariate regressions of inguinal hernia surgery counts in the outpatient setting and in the inpatient setting. The key explanatory variable is the time-varying Medicare payment rate specific to the procedure and hospital. Control variables include time-varying hospital and county characteristics and hospital and year-fixed effects. Principal Findings
Outpatient hernia surgeries fell in response to OPPS-induced rate cuts. The volume of inpatient hernia repair surgeries did not increase in response to reductions in the outpatient reimbursement rate. Conclusions
Potential substitution from the outpatient setting to the inpatient setting does not pose a serious threat to Medicare\u27s efforts to contain hospital outpatient costs
Abdominal spilled stones: ultrasound findings
Laparoscopic cholecystectomy (LC) is the treatment of choice for uncomplicated symptomatic gallstones. Spillage of stones due to gallbladder rupture has been reported in up to 33% of all LCs, but clinical sequelae caused by dropped gallstones are uncommon. We recently observed two patients with retained stones after LC. Correct diagnosis was made by abdominal ultrasonography (US) in both cases. In the first patient, who presented with fever, malaise, and weight loss 18 months after LC, abdominal US revealed hypoechoic focal lesions containing hyperechoic images with posterior shadowing of the liver and spleen. US-guided aspiration biopsies of these lesions yielded purulent material, and the injection and aspiration of saline solution provoked rolling movements of the hyperechoic images. Laparotomy confirmed the diagnosis of abscess-containing spilled gallstones. In the second patient, multiple hyperechoic images with posterior shadowing were observed in the Morison pouch during a routine US examination. The diagnosis of retained stones was consistent with the history of gallstone spillage during LC performed 2 months previously and was confirmed by computed tomographic findings of hyperdense images in the Morison pouch. The patient was asymptomatic, and treatment was thus deferred. Our experience suggests that US can be very useful in the detection of gallstones spilled during LC
