Using patient flow analysis with real-time patient tracking to optimize radiation oncology consultation visits.

PURPOSE: Clinical efficiency is a key component of the value-based care model and a driver of patient satisfaction. The purpose of this study was to identify and address inefficiencies at a high-volume radiation oncology clinic. METHODS AND MATERIALS: Patient flow analysis (PFA) was used to create process maps and optimize the workflow of consultation visits in a gastrointestinal radiation oncology clinic at a large academic cancer center. Metrics such as cycle times, waiting times, and rooming times were assessed by using a real-time patient status function in the electronic medical record for 556 consults and compared between before vs after implementation of the PFA recommendations. RESULTS: The initial PFA revealed four inefficiencies: (1) protracted rooming time, (2) inefficient communications, (3) duplicated tasks, and (4) ambiguous clinical roles. We analyzed 485 consult-visits before the PFA and 71 after the PFA. The PFA recommendations led to reductions in overall median cycle time by 21% (91 min vs 72 min, p < 0.001), in cumulative waiting times by 64% (45 min vs 16 min; p < 0.001), which included waiting room time (14 min vs 5 min; p < 0.001) and wait for physician (20 min vs. 6 min; p < 0.001). Slightly less than one-quarter (22%) of consult visits before the PFA lasted > 2 h vs. 0% after implementation of the recommendations (p < 0.001). Similarly, the proportion of visits requiring < 1 h was 16% before PFA vs 34% afterward (p < 0.001). CONCLUSIONS: PFA can be used to identify clinical inefficiencies and optimize workflows in radiation oncology consultation clinics, and implementing their findings can significantly improve cycle times and waiting times. Potential downstream effects of these interventions include improved patient experience, decreased staff burnout, financial savings, and opportunities for expanding clinical capacity.

Value based care and bundled payments: Anesthesia care costs for outpatient oncology surgery using time-driven activity-based costing.

BACKGROUND: With the movement towards bundled payments, stakeholders should know the true cost of the care they deliver. Time-driven activity-based costing (TDABC) can be used to estimate costs for each episode of care. In this analysis, TDABC is used to both estimate the costs of anesthesia care and identify the primary drivers of those costs of 11 common oncologic outpatient surgical procedures. METHODS: Personnel cost were calculated by determining the hourly cost of each provider and the associated process time of the 11 surgical procedures. Using the anesthesia record, drugs, supplies and equipment costs were identified and calculated. The current staffing model was used to determine baseline personnel costs for each procedure. Using the costs identified through TDABC analysis, the effect of different staffing ratios on anesthesia costs could be predicted. RESULTS: Costs for each of the procedures were determined. Process time and costs are linearly related. Personnel represented 79% of overall cost while drugs, supplies and equipment represented the remaining 21%. Changing staffing ratios shows potential savings between 13% and 28% across the 11 procedures. CONCLUSIONS: TDABC can be used to estimate the costs of anesthesia care. This costing information is critical to assessing the anesthesiology component in a bundled payment. It can also be used to identify areas of cost savings and model costs of anesthesia care. CRNA to anesthesiologist staffing ratios profoundly influence the cost of care. This methodology could be applied to other medical specialties to help determine costs in the setting of bundled payments.

Measuring the value of process improvement initiatives in a preoperative assessment center using time-driven activity-based costing.

BACKGROUND: The value and impact of process improvement initiatives are difficult to quantify. We describe the use of time-driven activity-based costing (TDABC) in a clinical setting to quantify the value of process improvements in terms of cost, time and personnel resources. PROBLEM: Difficulty in identifying and measuring the cost savings of process improvement initiatives in a Preoperative Assessment Center (PAC). GOALS: Use TDABC to measure the value of process improvement initiatives that reduce the costs of performing a preoperative assessment while maintaining the quality of the assessment. STRATEGY: Apply the principles of TDABC in a PAC to measure the value, from baseline, of two phases of performance improvement initiatives and determine the impact of each implementation in terms of cost, time and efficiency. RESULTS: Through two rounds of performance improvements, we quantified an overall reduction in time spent by patient and personnel of 33% that resulted in a 46% reduction in the costs of providing care in the center. The performance improvements resulted in a 17% decrease in the total number of full time equivalents (FTE's) needed to staff the center and a 19% increase in the numbers of patients assessed in the center. Quality of care, as assessed by the rate of cancellations on the day of surgery, was not adversely impacted by the process improvements.

Subacute penile numbness after brachytherapy for prostate cancer.

PURPOSE: Penile numbness is a rare complication of permanent prostate brachytherapy, and optimal clinical management remains unclear. We present such a case and discuss pathophysiology and clinical management strategies. METHODS AND MATERIALS: A 68-year-old male presented with a serum prostate-specific antigen level of 6.9 ng/mL, Gleason score of 7 (3+4), and clinical T1c adenocarcinoma of the prostate. After a permanent prostate brachytherapy implant with (125)I monotherapy to a dose of 145Gy, the patient developed complete penile numbness postoperatively on the third day. RESULTS: The patient experienced complete restoration of penile sensation and function by postoperative day 9 with conservative management. CONCLUSIONS: Subacute penile shaft numbness after brachytherapy is rare and is caused by dorsal penile nerve compression. Over the course of a week, the restoration of penile sensation is likely to occur with conservative management.

Ongoing provision of individual clinician performance data improves practice behavior.

BACKGROUND: Clinical practice guidelines summarize evidence from science and attempt to translate those findings into clinical practice. Pervasive and consistent adoption of these guidelines into daily provider practice has proven slow. METHODS: Using postoperative nausea and vomiting (PONV) prophylaxis guideline compliance as our metric, we compared the effects of continuing medical education (CME) alone (I), CME with a single snapshot of provider compliance (II), and ongoing reporting of provider compliance data without further CME (III). We retrospectively analyzed guideline compliance of 23,279 anesthetics at the University of Texas M.D. Anderson Cancer Center. Compliance was defined as a patient with 1 risk factor for PONV receiving at least 1 antiemetic, 2 risk factors receiving at least 2 antiemetics, and 3 risk factors receiving at least 3 antiemetics. Drugs of the same class were counted as single antiemetic administration. Propofol-based anesthetic techniques were counted as receiving 1 antiemetic. Patients with 0 risk factors for PONV were not included. We estimated the compliance rates for each of the 4 time periods of the study adjusting for multiple observations on the same clinician. Individual performance feedback was given once at 6 months after intervention I coincident with a refresher presentation on PONV (start of intervention II) and on an ongoing quarterly basis during intervention III. RESULTS: Compliance rates were not significantly influenced with CME (intervention I) compared with baseline behavior (54.5% vs 54.4%, P = 0.9140). Significant improvement occurred during the time period when CME was paired with performance data (intervention II) compared with intervention I (59.2% vs 54.4%, P = 0.0002). Further significant improvement occurred when data alone were presented (intervention III) compared with intervention II (65.1% vs 59.2%, P < 0.0001). For patients with 3 risk factors, we saw significant improvement in compliance rates during intervention III (P = 0.0002). In post hoc analysis of overtreatment, the percentage differences between the baseline and time period III decreased as the number of risk factors increased. CONCLUSIONS: We observed the greatest improvement in guideline compliance with ongoing personal performance feedback. Provider feedback can be an effective tool to modify clinical practice but can have unanticipated consequences.

The effect of an anatomically classified procedure on antiemetic administration in the postanesthesia care unit.

BACKGROUND: The effect of the type of surgical procedure on postoperative nausea and vomiting (PONV) rate has been debated in the literature. Our goal in this retrospective database study was to investigate the effect the type of surgical procedure (categorized and compared anatomically) has on antiemetic therapy within 2 h of admission to the postanesthesia care unit (PACU). METHODS: We retrospectively analyzed data for oncology surgeries (n = 18,109), from our automated anesthesia information system database. We classified the types of surgical procedures anatomically into seven categories, with the integumentary musculoskeletal and the superficial surgeries chosen as the referent group. Our analysis included nine other risk factors for each patient, such as gender, smoking status, history of PONV or motion sickness, duration of anesthesia, number of prophylactic antiemetics administered, intraoperative opioids, ketorolac, epidural use, and postoperative opioids. Multivariate logistic regression was used to assess the effect of the type of surgery on antiemetic administration within the first 2 h of PACU admission, while adjusting for the other risk factors. RESULTS: Compared with integumentary musculoskeletal and superficial surgeries, patients undergoing neurological (P < 0.0001), head or neck (P < 0.0001), and abdominal (P < 0.0001) surgeries were administered PACU antiemetic significantly more often, whereas patients undergoing thoracic surgeries were administered PACU antiemetic significantly less often (P = 0.02). Breast or axilla (P = 0.74) and endoscopic (P = 0.28) procedures did not differ from the referent category. Female, nonsmoker, history of PONV or motion sickness, anesthesia duration, and intraoperative and postoperative opioid administration were significantly associated with antiemetic administration during early PACU admission. CONCLUSIONS: Using our automated anesthesia information system database, we found that the type of surgery, when categorized anatomically, was associated with an increased frequency of early PACU antiemetic administration in our population.

Improved postoperative pain control using thoracic paravertebral block for breast operations.

Thoracic paravertebral block (PVB) in breast surgery can provide regional anesthesia during and after surgery with the potential advantage of decreasing postoperative pain. We report our institutional experience with PVB over the initial 8 months of use. All patients undergoing breast operations at the ambulatory care building from September 09, 2005 to June 28, 2005 were reviewed. Comparison was performed between patients receiving PVB and those who did not. Pain scores were assessed immediately, 4 hours, 8 hours and the morning after surgery. 178 patients received PVB and 135 patients did not. Patients were subdivided into three groups: Group A-segmental mastectomy only (n = 89), Group B-segmental mastectomy and sentinel node surgery (n = 111) and Group C-more extensive breast surgery (n = 113). Immediately after surgery there was a statistically significant difference in the number of patients reporting pain between PVB patients and those without PVB. At all time points up until the morning after surgery PVB patients were significantly less likely to report pain than controls. Patients in Group C who received PVB were significantly less likely to require overnight stay. The average immediate pain scores were significantly lower in PVB patients than controls in both Group B and Group C and approached significance in Group A. PVB in breast surgical patients provided improved postoperative pain control. Pain relief was improved immediately postoperatively and this effect continued to the next day after surgery. PVB significantly decreased the proportion of patients that required overnight hospitalization after major breast operations and therefore may decrease cost associated with breast surgery.

Prospective randomized trial of paravertebral block for patients undergoing breast cancer surgery.

BACKGROUND: The goal of the current study was to evaluate the effect of regional anesthesia using paravertebral block (PVB) on postoperative pain after breast surgery. METHODS: Patients undergoing unilateral breast surgery without reconstruction were randomized to general anesthesia (GA) only or PVB with GA and pain scores assessed. RESULTS: Eighty patients were randomized (41 to GA and 39 to PVB with GA). Operative times were not significantly different between groups. Pain scores were lower after PVB compared to GA at 1 hour (1 vs 3, P = .006) and 3 hours (0 vs 2, P = .001) but not at later time points. The overall worst pain experienced was lower with PVB (3 vs 5, P = .02). More patients were pain-free in the PVB group at 1 hour (44% vs 17%, P = .014) and 3 hours (54% vs 17%, P = .005) postoperatively. CONCLUSIONS: PVB significantly decreases postoperative pain up to 3 hours after breast cancer surgery.

Adaptation of the OODA Loop to reduce postoperative nausea and vomiting in a high-risk outpatient oncology population.

Postoperative nausea and vomiting (PONV) remains a ubiquitous concern for surgical outpatients with published rates ranging from 14% to 80%. An evidence-based approach was used to reduce PONV in a high-risk adult outpatient oncology population. The Observe, Orient, Decide, and Act (OODA) Loop, a rapid cycle management strategy, was adapted for use in an outpatient surgery center with six ORs. A PONV prophylaxis protocol was developed and adapted until a stable PONV rate was achieved. A combination of dexamethasone, promethazine, and ondansetron was used in patients with one to three PONV risk factors. Patients with four major risk factors received an additional intervention. The PONV rate for the final protocol stabilized below 4% by 46 weeks and remained stable through 79 weeks. The OODA paradigm provides an effective technique for interfacing health care research with clinical practice. In this case, an effective PONV prophylaxis plan was developed from within a collaborative nursing and medical setting.

Minimally invasive parathyroidectomy complicated by pneumothoraces: a report of 4 cases.

The traditional approach to primary hyperparathyroidism has been a bilateral neck exploration for evaluation of all four parathyroid glands. With the advent of minimally invasive surgery, minimally invasive parathyroidectomy has become a popular approach for the treatment of parathyroid adenomas. Though exceedingly rare, pneumothorax formation is a potential complication following this procedure. In this paper, we report four cases of pneumothorax following minimally invasive parathyroidectomies. The commonality in all these cases was positioning with extreme neck hyperextension. Additional risks in three patients were dissection in the superior mediastinum, traction on the thyrothymic ligament, and a low-lying inferior parathyroid gland. One patient developed a pneumothorax prior to dissection along the superior mediastinum. This suggests that further risk factors may be heat conduction from the electrocautery and total intravenous anesthesia with spontaneously breathing of the patient.

Data security issues arising from integration of wireless access into healthcare networks.

The versatility of having Ethernet speed connectivity without wires is rapidly driving adoption of wireless data networking by end users across all types of industry. Designed to be easy to configure and work among diverse platforms, wireless brings online data to mobile users. This functionality is particularly useful in modern clinical medicine. Wireless presents operators of networks containing or transmitting sensitive and confidential data with several new types of security vulnerabilities, and potentially opens previously protected core network resources to outside attack. Herein, we review the types of vulnerabilities, the tools necessary to exploit them, and strategies to thwart a successful attack.
