Can children undergoing ophthalmologic examinations under anesthesia be safely anesthetized without using an IV line?
To document that with proper patient and procedure selection, children undergoing general inhalational anesthesia for ophthalmologic exams (with or without photos, ultrasound, laser treatment, peri-ocular injection of chemotherapy, suture removal, and/or replacement of ocular prosthesis) can be safely anesthetized without the use of an intravenous (IV) line. Children are rarely anesthetized without IV access placement. We performed a retrospective study to determine our incidence of IV access placement during examinations under anesthesia (EUA) and the incidence of adverse events that required intraoperative IV access placement.
Data collected from our operating room (OR) information system includes but is not limited to diagnosis, anesthesiologist, surgeon, and location of IV catheter (if applicable), patient's date of birth, actual procedure, and anesthesia/procedure times. We reviewed the OR and anesthetic records of children (>1 month and <10 years) who underwent EUAs between January 1, 2003 and May 31, 2009. We determined the percentage of children who were anesthetized without IV access placement, as well as the incidence of any adverse events that required IV access placement, intraoperatively.
We analyzed data from 3196 procedures performed during a 77-month period. Patients' ages ranged from 1 month to 9 years. Overall, 92% of procedures were performed without IV access placement. Procedure duration ranged from 1-39 minutes. Reasons for IV access placement included parental preference for antinausea medication and/or attending preference for IV access placement. No child who underwent anesthesia without an IV line had an intraoperative adverse event requiring insertion of an IV line.
Our data suggest that for children undergoing general anesthesia for ophthalmologic exams (with or without photos, ultrasound, laser treatment, intraocular injection of chemotherapy, suture removal, and/or replacement of ocular prosthesis), anesthesia can be safely conducted without placement of an IV line
Intravitreal injection analysis at the Bascom Palmer Eye Institute: evaluation of clinical indications for the treatment and incidence rates of endophthalmitis
To report the incidence of endophthalmitis, in addition to its clinical and microbiological aspects, after intravitreal injection of vascular-targeting agents.
A retrospective review of a consecutive series of 10,142 intravitreal injections of vascular targeting agents (bevacizumab, ranibizumab, triamcinolone acetonide, and preservative-free triamcinolone acetonide) between June 1, 2007 and January 31, 2010, performed by a single service (TGM) at the Bascom Palmer Eye Institute.
One case of clinically-suspected endophthalmitis was identified out of a total of 10,142 injections (0.009%), presenting within three days of injection of bevacizumab. The case was culture-positive for Staphylococcus epidermidis. Final visual acuity was 20/40 after pars plana vitrectomy surgery.
In this series, the incidence of culture-positive endophthalmitis after intravitreal injection of vascular agents in an outpatient setting was very low. We believe that following a standardized injection protocol, adherence to sterile techniques and proper patient follow-up are determining factors for low incidence rates

Failure to recognize loss of incoming data in an anesthesia record-keeping system may have increased medical liability
Automated anesthesia record-keeping systems (AARKs) are increasingly being used. There is a perception that AARKs may limit medical liability. We report a case in which our AARK may have increased our medical liability exposure. Nine months after a patient suffered a serious intraoperative complication, the anesthesiologist was named (as one of several defendants) in a claim alleging failure to properly monitor anesthetic care. One reason why the anesthesiologist was named related to a gap of 93 min in which no vital signs were documented in the anesthesia record. Relying on the physiological monitors to assess the patient's condition, the anesthesiologist did not recognize the interruption of data transmission, because the "active" medication window obscured the graphical display of the vital sign window

The medicolegal importance of enhancing timeliness of documentation when using an anesthesia information system and the response to automated feedback in an academic practice
Documentation should ideally occur in real time immediately after completion of a service. Although electronic records often do not print the time that documentation notes were entered on the medical record, automated anesthesia record keeping systems store an audit trail that time stamps events entered by all anesthesia providers. As more lawyers become aware of this fact and requisition audit trails, prospective charting of necessary documentation may undermine the integrity of an anesthesia care team accused of malpractice, with potentially significant medicolegal consequences. We changed existing documentation practices of a large academic practice via a three-step process. Educational sessions increased the percentage of cases with correct timing of emergence documentation from 25% to 60% over a 2-mo period. Automated email performance feedback further increased correct note timing to 70%. When combined with personal contact by a member of the billing office and email copy notification of the chair, the percentage increased to >99.5%. The behavioral change was seen in all individuals, as 95% of attendings had < or = 2 records/mo with untimely documentation at the end of the study period. Once the habits were ingrained, further input was rarely necessary over the next 9 mo. This suggests physician behavioral change related to work process flow, unlike that related to patient care, is easily sustained
Changing medical group behaviors: increasing the rate of documentation of quality assurance events using an anesthesia information system
In the United States, quality assurance (QA) documentation is required by numerous agencies for each anesthetic performed. The goal of this study was to determine the effect of several interventions on the voluntary completion rate of QA documentation. We hypothesized that optimizing workflow integration would increase both QA completion rates and complication capture rates and promote long-term successful changes in reporting behavior. Whereas electronic scanning of anesthetic records may automate some aspects of QA, there will continue to be a need for anesthesiologists to enter QA documentation that cannot be automated. Starting from a baseline completion rate of 48%, we instituted a series of interventions. We successively increased the completion rate to 55% (education), 68% (workflow integration), and 78% (individual feedback). Each intervention increased the completion rate from the previous intervention (P < 0.001). The increased completion rate suggests better overall data capture, because the percentage of "no complication" entries decreased. After the study period, the completion rate increased to 94%, principally because of the improved workflow integration. As implementation of anesthesia information systems increases, attention to user interface design may be a key component in the functionality and utility of these systems

Discrepancies in medication entries between anesthetic and pharmacy records using electronic databases
Accurate recording of disposition of controlled substances is required by regulatory agencies. Linking anesthesia information management systems (AIMS) with medication dispensing systems may facilitate automated reconciliation of medication discrepancies.
In this retrospective investigation at a large academic hospital, we reviewed 11,603 cases (spanning an 8-mo period) comparing records of medications (i.e., narcotics, benzodiazepines, ketamine, and thiopental) recorded as removed from our automated medication dispensing system with medications recorded as administered in our AIMS.
In 15% of cases, we found discrepancies between dispensed versus administered medications. Discrepancies occurred in both the AIMS (8% cases) and the medication dispensing system (10% cases). Although there were many different types of user errors, nearly 75% of them resulted from either an error in the amount of drug waste documented in the medication dispensing system (35%); or an error in documenting the medication in the AIMS (40%).
A significant percentage of cases contained data entry errors in both the automated dispensing and AIMS. This error rate limits the current practicality of automating the necessary reconciliation. An electronic interface between an AIMS and a medication dispensing system could alert users of medication entry errors prior to finalizing a case, thus reducing the time (and cost) of reconciling discrepancies

Evidence-based management assessment of return on investment from anesthesia information management systems
A systematic and comprehensive review of the scientific literature revealed 4 evidence-based methods that contribute to a positive return on investment from anesthesia information management systems (AIMS): reducing anesthetic-related drug costs, improving staff scheduling and reducing staffing costs, increasing anesthesia billing and capture of anesthesia-related charges, and increased hospital reimbursement through improved hospital coding. There were common features to these interventions. Whereas an AIMS may be the ideal choice to achieve these cost reductions and revenue increases, alternative existing systems may be satisfactory for the studied applications (i.e., the incremental advantage to the AIMS may be less than predicted from applying each study to each facility). Savings are likely heterogeneous among institutions, making an internal survey using standard accounting methods necessary to perform a valid return on investment analysis. Financial advantages can be marked for the anesthesia providers, although hospitals are more likely to purchase the AIMS
Prediction of Uterine Contractions Using Knowledge-Assisted Sequential Pattern Analysis
The usage of the systemic opioid remifentanil in relieving the labor pain has attracted much attention recently. An optimal dosing regimen for administration of remifentanil during labor relies on anticipating the timing of uterine contractions. These predictions should be made early enough to maximize analgesia efficacy during contractions and minimize the impact of the medication between contractions. We have designed a knowledge-assisted sequential pattern analysis framework to 1) predict the intrauterine pressure in real time; 2) anticipate the next contraction; and 3) develop a sequential association rule mining approach to identify the patterns of the contractions from historical patient tracings (HT)
