Initial Clinical Evaluation of a Handheld Device for Detecting Retained Surgical Gauze Sponges Using Radiofrequency Identification Technology

Alex Macario, Dean Morris, Sharon Morris
Archives of Surgery, 2006 July 1, 2006

HYPOTHESIS: A handheld wand-scanning device (1.5 lb, battery powered, 10 x 10 x 1.5 in) has been developed to detect commonly used surgical gauze sponges, which have been tagged with a radiofrequency identification (RFID) chip. We tested the hypothesis that this wand device has a successful detection rate of 100%, with 100% specificity and 100% sensitivity.

DESIGN: Prospective, blinded, experimental clinical trial.

SETTING: Stanford University Medical Center, Stanford, Calif.

PATIENTS: Eight patients undergoing abdominal or pelvic surgery.

Economics of one-stage versus two-stage bilateral total knee arthroplasties

Alex Macario, Schilling P, Rubio R, Bhalla A, Goodman S
Clinical Orthopedics and Related Research, 2003 September 1, 2003

Patients requiring bilateral total knee arthroplasties may have both joints replaced simultaneously during one hospitalization (one-stage) or during two separate hospitalizations (two-stage). The goals of the current study were to retrospectively analyze discharge patterns for 91 patients who had one-stage bilateral total knee arthroplasties and 32 patients who had two-stage surgeries, and to quantify their in-hospital costs and their costs if the patients were discharged from the hospital to an inpatient unit.

What Questions do Patients Undergoing Lower Extremity Joint Replacement Surgery Have

Alex Macario, Schilling P, Rubio R, Bhalla A, Goodman S
BMC Health Services Research , 2003 June 24, 2003

BACKGROUND: The value of the Internet to deliver preoperative education would increase if there was variability in questions patients want answered. This study's goal was to have patients consulting an orthopedic surgeon about undergoing either a total hip arthroplasty (THA) or a total knee arthroplasty (TKA) rate the importance of different questions concerning their care. METHODS: We assembled questions patients might have about joint replacement surgery by analyzing the literature and querying a pilot group of patients and surgeons.

Operating Room Utilization Alone is Not an Accurate Metric for the Allocation of Operating Room Block Time to Individual Surgeons with Low Caseloads

Dexter F, Alex Macario, Traub R, Lubarsky D
Anesthesiology , 2003 May 1, 2003

INTRODUCTION: Many surgical suites allocate operating room (OR) block time to individual surgeons. If block time is allocated to services/groups and yet the same surgeon invariably operates on the same weekday, for all practical purposes block time is being allocated to individual surgeons. Organizational conflict occurs when a surgeon with a relatively low OR utilization has his or her allocated block time reduced.

Pharmacy Cost of Delivering Post-operative Analgesia to Patients Undergoing Joint Replacement Surgery, The

Alex Macario, McCoy M
The Journal of Pain, 2003 February 1, 2003

Few data exist on the distribution of pharmaceutical costs for inpatient surgical procedures across different drug categories (eg, analgesia, anti-infectives). The goals of this study were to categorize pharmaceuticals administered to patients after joint replacement surgery and then to take the hospital's perspective and quantify the pharmacy cost of delivering postoperative analgesia to these patients.

How to Release Allocated Operating Room Time to Increase Efficiency

Dexter F, Traub R, Alex Macario
Anesthesia & Analgesia, 2003 February 1, 2003

At many facilities, surgeons and patients choose the day of surgery, cases are not turned away, and staffing is adjusted to maximize operating room (OR) efficiency. If a surgical service has already filled its allocated OR time, but has an additional case to schedule, then OR efficiency is increased by scheduling the new case into the OR time of a different service with much underutilized OR time. The latter service is said to be "releasing" its allocated OR time. In this study, we analyzed 3 years of scheduling data from a medium-sized and a large surgical suite.
