Comparative Cost Effectiveness of Reflux-Based and Reflux-Independent Strategies for Barrett's Esophagus Screening

INTRODUCTION

Minimally invasive tests for Barrett's esophagus (BE) detection have raised the prospect of broader nonreflux-based testing. Cost-effectiveness studies have largely studied men aged 50 years with chronic gastroesophageal reflux disease (GERD) symptoms. We evaluated the comparative cost effectiveness of BE screening tests in GERD-based and GERD-independent testing scenarios.

METHODS

Markov modeling was performed in 3 scenarios in 50 years old individuals: (i) White men with chronic GERD (GERD-based); (ii) GERD-independent (all races, men and women), BE prevalence 1.6%; and (iii) GERD-independent, BE prevalence 5%. The simulation compared multiple screening strategies with no screening: sedated endoscopy (sEGD), transnasal endoscopy, swallowable esophageal cell collection devices with biomarkers, and exhaled volatile organic compounds. A hypothetical cohort of 500,000 individuals followed for 40 years using a willingness to pay threshold of $100,000 per quality-adjusted life year (QALY) was simulated. Incremental cost-effectiveness ratios (ICERs) comparing each strategy with no screening and comparing screening strategies with each other were calculated.

RESULTS

In both GERD-independent scenarios, most non-sEGD BE screening tests were cost effective. Swallowable esophageal cell collection devices with biomarkers were cost effective (<$35,000/QALY) and were the optimal screening tests in all scenarios. Exhaled volatile organic compounds had the highest ICERs in all scenarios. ICERs were low (<$25,000/QALY) for all tests in the GERD-based scenario, and all non-sEGD tests dominated no screening. ICERs were sensitive to BE prevalence and test costs.

DISCUSSION

Minimally invasive nonendoscopic tests may make GERD-independent BE screening cost effective. Participation rates for these strategies need to be studied.

Global demand for cancer surgery and an estimate of the optimal surgical and anaesthesia workforce between 2018 and 2040: a population-based modelling study

BACKGROUND

The growing demand for cancer surgery has placed a global strain on health systems. In-depth analyses of the global demand for cancer surgery and optimal workforce requirements are needed to plan service provision. We estimated the global demand for cancer surgery and the requirements for an optimal surgical and anaesthesia workforce, using benchmarks based on clinical guidelines.

METHODS

Using models of benchmark surgical use based on clinical guidelines, we estimated the proportion of cancer cases with an indication for surgery across 183 countries, stratified by income group. These proportions were multiplied by age-adjusted national estimates of new cancer cases using GLOBOCAN 2018 data and then aggregated to obtain the estimated number of surgical procedures required globally. The numbers of cancer surgical procedures in 44 high-income countries were divided by the actual number of surgeons and anaesthetists in the respective countries to calculate cancer procedures per surgeon and anaesthetist ratios. Using the median (IQR) of these ratios as benchmarks, we developed a three-tiered optimal surgical and anaesthesia workforce matrix, and the predictions were extrapolated up to 2040.

FINDINGS

Our model estimates that the number of cancer cases globally with an indication for surgery will increase by 5 million procedures (52%) between 2018 (9 065 000) and 2040 (13 821 000). The greatest relative increase in surgical demand will occur in 34 low-income countries, where we also observed the largest gaps in workforce requirements. To match the median benchmark for high-income countries, the surgical workforce in these countries would need to increase by almost four times and the anaesthesia workforce by nearly 5·5 times. The greatest increase in optimal workforce requirements from 2018 to 2040 will occur in low-income countries (from 28 000 surgeons to 58 000 surgeons; 107% increase), followed by lower-middle-income countries (from 166 000 surgeons to 277 000 surgeons; 67% increase).

INTERPRETATION

The global demand for cancer surgery and the optimal workforce are predicted to increase over the next two decades and disproportionately affect low-income countries. These estimates provide an appropriate framework for planning the provision of surgical services for cancer worldwide.

Evaluating patient preferences for thermal ablation versus nonthermal, nontumescent varicose vein treatments

OBJECTIVE

To measure patient preferences for attributes associated with thermal ablation and nonthermal, nontumescent varicose vein treatments.

METHODS

Data were collected from an electronic patient preference survey taken by 70 adult participants (aged 20 years or older) at three Center for Vein Restoration clinics in New Jersey from July 19, 2019, through August 13, 2019. Survey participation was voluntary and anonymous (participation rate of 80.5% [70/87]). Patients were shown 10 consecutive screens that displayed three hypothetical treatment scenarios with different combinations of six attributes of interest and a none option. Choice-based conjoint analysis estimated the relative importance of different aspects of care, trade-offs between these aspects, and total satisfaction that respondents derived from different healthcare procedures. Market simulation analysis compared clusters of attributes mimicking thermal ablation and nonthermal, nontumescent treatments.

RESULTS

Of the six attributes studied, out-of-pocket (OOP) expenditures were the most important to patients (37.2%), followed by postoperative discomfort (17.1%), risk of adverse events (16.3%), time to return to normal activity (11.0%), number of injections (10.0%), and number of visits (8.4%). Patients were willing to pay the most to avoid postoperative discomfort ($68.9) and risk of adverse events ($65.8). The market simulation analysis found that, regardless of the level of OOP spending, 60% to 80% of respondents favored attribute combinations corresponding with nonthermal, nontumescent procedures over thermal ablation, and that less than 1% of participants would forgo either treatment under no cost sharing.

CONCLUSIONS

Patients are highly sensitive to OOP costs for minimally invasive varicose vein treatments. Market simulation analysis favored nonthermal, nontumescent procedures over thermal ablation.

Clinical and economic burden of postoperative nausea and vomiting: Analysis of existing cost data

Postoperative nausea and vomiting (PONV) is an undesirable outcome that occurs in up to 30% of patients. Over the years, the cost of treating PONV has decreased due to the availability of cheaper yet effective antiemetics. Limiting PONV development benefits the hospital system as studies have shown that prevention is associated with shorter post-anesthesia care unit (PACU) stays as well as decreased supply costs and staffing burden. The financial burden for prophylaxis against PONV has been shown to be less than what patients are willing to pay to prevent the development of PONV. Studies have also shown that prevention of initial development of PONV limits readmission rates, which is beneficial to both the patient and the hospital. Owing to recent economic analysis and reductions in antiemetic prices, the patient's preference for comfort, the hospital's commitment to providing the best care, and the system's desire for fiscal prudence are aligned. This culminates in recommending PONV prophylaxis for all patients undergoing anesthesia.

ECONOMIC EFFECTIVENESS OF DIFFERENT METHODS OF ANESTHESIA OF CURETTAGE OF UTERINE CAVITY

Anesthesia of curettage of uterine cavity (CUC) at postoperative period causes additional expenses. Preventive intraoperative anesthesia makes it possible to reduce these expenses and provide significant positive economic effect on state budget. The objective of this research is determination of influence of different methods of anesthesia of CUC on cash value of anesthetic maintenance of CUC and the possibility of saving of budgetary funds. 128 women took part in the research. They underwent the procedure of CUC. Anesthetic maintenance was performed using different medicamental combinations and their dosages. Mathematical calculation of the cost of each CUC stage was done considering the cost of consumables, medical preparations and value of labor of medical staff. In the course of this research, it was proven that a combination of additional use of dexketoprofen (at the stage of premedication of CUC) and performing preventive intraoperative applicational anesthesia with bupivacaine solution can save 130 452,26UAH of wage fund per year and general budget savings within the confines of a state can each 9 954 617,67UAH per year.

On-table extubation in neonates undergoing anoplasty: an experience of anesthetic management on the concept of fast-tracking anesthesia: A pilot study

Fast-track anesthesia (FTA) is difficult to achieve in neonates due to immature organ function and high rates of perioperative events. As a high-risk population, neonates require prolonged postoperative mechanical ventilation, which may lead to contradictions in cases where neonatal intensive care unit resources and ventilator facilities are limited. The choice of anesthesia strategy and anesthetic can help achieve rapid postoperative rehabilitation and save hospitalization costs. The authors describe their experience with maintaining spontaneous breathing in neonates undergoing anoplasty without opioids or muscle relaxants.This retrospective chart review included neonates who underwent anoplasty in the authors' institution. Twelve neonates who underwent the procedure with atomized 5% lidocaine topical anesthesia around the glottis, combined with sevoflurane sedation and caudal anesthesia facilitating tracheal intubation without opioid and muscle relaxant comprised the FTA group. Ten neonates who underwent the intervention with routine anesthesia techniques in the same period comprised the control group (group C).The surgical success rate in the FTA group was 91.7%. There were no severe complications related to lidocaine administered around the glottis. Extubation time was significantly shorter in the FTA group than in group C (4 [2.5, 5.2] vs 81.5 [60.6, 96.8], respectively; P < .01). The duration of stay in the surgical intensive care unit (SICU) was longer in group C than in the FTA group (2 [2.0, 2.6] vs 1 [0.9, 2.0], respectively; P = .006,). A statistically significant lower rate of extubation-cough was noted after endotracheal tube removal in the FTA group compared with group C (18% vs 90%, respectively; P < .001). There was no difference in the duration of anesthesia or hospitalization costs between the 2 groups. No neonates required re-intubation after extubation.On-table extubation via 5% atomized lidocaine topical anesthesia around the glottis for tracheal intubation combined with sevoflurane sedation and caudal anesthesia without opioid and muscle relaxant was feasible in neonates undergoing anoplasty. This reduced time to extubation, length of SICU stay and saved resources. A similar trend in cost savings was also found; nevertheless, more studies are needed to confirm these results.

Comparison of Anesthesia Times and Billing Patterns by Anesthesia Practitioners

Importance

Most physicians must exercise discretion in choosing billing details that determine payment for their services. Understanding the degree to which physicians inappropriately use this discretion has important implications for payment policies. However, separating higher case complexity from inappropriate billing has made this a challenging issue to study. Anesthesia offers a useful test case because practitioners are partly compensated by self-reported length of time (anesthesia time) spent on a case.

Objective

To characterize the incidence and consequences of inappropriate billing practices among anesthesia practitioners.

Design, Setting, and Participants

In this cross-sectional study of data from a large anesthesia registry, 6 261 955 procedures performed by 4221 anesthesia practitioners (physician anesthesiologists, nurse anesthetists, and anesthesiologist assistants) between January 1, 2010, and March 31, 2015, were studied. A total of 3047 practitioners practiced primarily in community hospitals, whereas 453 practiced primarily in university hospitals and 721 practiced in other settings (eg, specialty hospital).

Exposures

Practitioners with anomalous patterns were identified as those reporting an unusually high number of anesthesia times ending in a multiple of 5 minutes (eg, 65 minutes).

Main Outcomes and Measures

Incidence of anomalous patterns among anesthesia practitioners and the increase in anesthesia times associated with these patterns.

Results

This study included 4221 practitioners who each performed at least 300 anesthetic procedures. Practitioners in the top fifth percentile reported anesthesia times ending in a multiple of 5 minutes a mean (SD) of 53.7% (13.7%) of the time (range, 36.8%-96.1%), whereas practitioners in the 6th to 10th percentiles reported anesthesia times ending in a multiple of 5 minutes a mean (SD) of 31.8% (2.0%) of the time (range, 29.2%-36.7%). Practitioners in the top fifth percentile submitted billing for anesthesia times that exceeded the expected time by a mean of 21.5 minutes (95% CI, 15.8-27.1 minutes).

Conclusions and Relevance

In this study, findings suggest that anesthesia practitioners with the highest tendency to report anesthesia times ending in a multiple of 5 minutes did so with high frequency, which reflects anomalous billing. These practitioners also sought payment for longer-than-expected anesthesia times, which would correspond to higher payment for their services.

The effects of graduate competency-based education and mastery learning on patient care and return on investment: a narrative review of basic anesthetic procedures

BACKGROUND

Despite the widespread implementation of competency-based education, evidence of ensuing enhanced patient care and cost-benefit remains scarce. This narrative review uses the Kirkpatrick/Phillips model to investigate the patient-related and organizational effects of graduate competency-based medical education for five basic anesthetic procedures.

METHODS

The MEDLINE, ERIC, CINAHL, and Embase databases were searched for papers reporting results in Kirkpatrick/Phillips levels 3-5 from graduate competency-based education for five basic anesthetic procedures. A gray literature search was conducted by reference search in Google Scholar.

RESULTS

In all, 38 studies were included, predominantly concerning central venous catheterization. Three studies reported significant cost-effectiveness by reducing infection rates for central venous catheterization. Furthermore, the procedural competency, retention of skills and patient care as evaluated by fewer complications improved in 20 of the reported studies.

CONCLUSION

Evidence suggests that competency-based education with procedural central venous catheterization courses have positive effects on patient care and are both cost-effective. However, more rigorously controlled and reproducible studies are needed. Specifically, future studies could focus on organizational effects and the possibility of transferability to other medical specialties and the broader healthcare system.

Fast-Track Cardiac Anesthesia: Choice of Anesthetic Agents and Techniques

Fast-track cardiac anesthesia (FTCA) incorporates early tracheal extubation, decreased length of intensive care unit (ICU) and hospital stay, and (ideally) should avoid or reduce complications to safely achieve cost-savings. A growing body of evidence from randomized trials has identified many anesthetic interventions that can improve outcome after cardiac surgery. These include new short-acting hypnotic, opioid, and neuromuscular blocking drugs. An effective FTCA program requires the appropriate selection of suitable patients, a lowdose opioid anesthetic technique, early tracheal extubation, a short stay in the ICU, and coordinated perioperative care. It is also dependent on the avoidance of postoperative complications such as excessive bleeding, myocardial ischemia, low cardiac output state, arrhythmias, sepsis, and renal failure. These complications will have a much greater adverse effect on hospital length of stay and healthcare costs. A number of clinical trials have identified interventions that can reduce some of these complications. The adoption of effective treatments into clinical practice should improve the effectiveness of FTCA.

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.

Example of cost calculations for an operating room and a post-anaesthesia care unit

OBJECTIVE

The aim of this study was to evaluate the cost of an operating room using data from our hospital. Using an accounting-based method helped us.

METHODS

Over the year 2012, the sum of direct and indirect expenses with cost sharing expenses allowed us to calculate the cost of the operating room (OR) and of the post-anaesthesia care unit (PACU).

RESULTS

The cost of the OR and PACU was €10.8 per minute of time offered. Two thirds of the direct expenses were allocated to surgery and one third to anaesthesia. Indirect expenses were 25% of the direct expenses. The cost of medications and single use medical devises was €111.45 per anaesthesia. The total cost of anaesthesia (taking into account wages and indirect expenses) was €753.14 per anaesthesia as compared to the total cost of the anaesthesia. The part of medications and single use devices for anaesthesia was 14.8% of the total cost.

CONCLUSION

Despite the difficulties facing cost evaluation, this model of calculation, assisted by the cost accounting controller, helped us to have a concrete financial vision. It also shows that a global reflexion is necessary during financial decision-making.

Costs optimization in anaesthesia

OBJECTIVES

The aim of this study is to analyze the direct cost of different anaesthetic techniques used within the Author's hospital setting and compare with costs reported in the literature.

METHODS

Mean cost of drugs and devices used in our local Department of Anaesthesia was considered in the present study. All drugs were supplied by the in-house Pharmacy Service of Parma's General Hospital. All calculation have been made using an hypothetical ASA1 patient weighting 70 kg. The quality of consumption and cost of inhalation anaesthesia with sevoflurane or desflurane at different fresh gas flow were analyzed, and the cost of total venous anaesthesia (TIVA) using propofol and remifentanil with balanced anaesthesia were also analyzed. In addition, direct costs of general, spinal and sciatic-femoral nerve block anaesthesia used for common plastic surgery procedures were assessed.

RESULT

The results of our study show that the cost of inhalational anaesthesia decreases using fresh gas flow below 1L, and the use of desflurane is more expensive. In our Hospital, the cost of TIVA is more or less equivalent to the costs of balanced anaesthesia with sevoflurane in surgical procedure lasting more than five hours. The direct cost was lower for the spinal anaesthesia compared with general anaesthesia and sciatic- femoral nerve block for some surgical procedures. (www.actabiomedica.it).

[Sedation as a Part of Monitored Anesthesia Care (MAC) and Its Introduction to Japanese Clinical Practice]

To relieve or eliminate distress caused by invasive medical procedures, sedation is often used in routine clinical practice. Monitored anesthesia care (MAC) is needed in patients who receive increased doses of sedatives and/or analgesics, which may suppress the respiratory, cardiac, and/or vascular systems. Deep sedation, in particular, suppreses the nomal protective reflexes. It requires careful monitoring and intervention for patients. In Japan, sedation is performed in a large number of cases. It is unreasonable that only anesthesiologists administer MAC. In fact, sedation is often performed by non-anesthesiologists. In these circumstances, education and training for non-anesthesiologists are important

[Quality assurance at the interface between anesthesia and transfusion medicine]

BACKGROUND

The current situation in hospitals is characterized by financial limitations and simultaneously by increasing demands on quality and safety. The operative interface between anesthesia and transfusion medicine affects both factors.

AIM

A detailed analysis was performed to evaluate the process quality at this operative interface at the University Hospital of Göttingen. The aim of the project was to revise und develop the structures and responsibilities at this interface, to dispose of weak points and to realize the optimization potential in the supply of blood products.

MATERIAL AND METHODS

A databank-based electronic data processing solution was established with the clear definition of responsibilities for the various workflow procedures and the written documentation of these definitions in standard operating protocols. In order to guarantee the necessary transparency a routine reporting system to the department of surgery was established. In addition, a continuous further development of the blood supply standard based on electronic report data was implemented.

RESULTS

By implementing the above named measures the rate of supplied to transfused blood products could be increased from 43.1 % to 55.7 %. The compliance with the blood supply standard improved continually over the first 18 months from 60.3 % to 92.3 %. The rate of supplied blood product deliveries without subsequent operation could be reduced from 9.0 % to 4.6  %. As a result of this optimization the supply costs in the internal cost allocation were reduced from 9,406 <euro> to 3,544 <euro>.

CONCLUSION

The measures described are appropriate to cost-effectively improve quality and patient safety. The optimization measures presented in this article can be implemented in other hospitals to increase quality and safety after individual adjustment to the local circumstances.

[Evaluation of muscle relaxant requirement for hospital anesthesia]

The rationale for cost-effectiveness of modern muscle relaxants (MR) administration in general anesthesia was evaluated. New MRs are more expensive than traditionally used pipecuronium and succinylcholine. However, the old MRs are often required as a block reversion with anticholinesterase medicines at the end of surgery, the longer artificial lung ventilation and observation in patients during recovery in intensive care unit. It was found that the district military hospital had done an annual average of about 900 general anesthesia assisted with artificial ventilation and muscle relaxation. About 2% of all anesthesias accrue to short-term anesthesia, the 27% to medium-term and 71% to long-term. 81% of the medium-term anesthesia accrue small hospitals. According to cost/effectiveness the most optimal muscle relaxants administration scheme for short-term (up to 30 min) anesthesia was mivacurium, for the operation of medium duration (30-120 min)--rocuronium, for long-term (120 min)--pipecuronium. An electronic form of annual report, which allows to obtain the necessary data for calculation of annual muscle relaxants demand and costs both in hospital and in the whole of the armed forces quickly, was developed.

Cost accounting in a surgical unit in a teaching hospital - a pilot study

INTRODUCTION

Economic constraints remain one of the major limitations on the quality of health care even in industrialised countries. Improvement of quality will require optimising facilities within available resources. Our objective was to determine costs of surgery and to identify areas where cost reduction is possible.

PATIENTS AND METHODS

80 patients undergoing routine major and intermediate surgery during a period of 6 months were selected at random. All consumables used and procedures carried out were documented. A unit cost was assigned to each of these. Costing was based on 3 main categories: preoperative (investigations, blood product related costs), operative (anaesthetic charges, consumables and theatre charges) and post-operative (investigations, consumables, hospital stay). Theatre charges included two components: fixed (consumables) and variable (dependent on time per operation).

RESULTS

The indirect costs (e.g. administration costs, 'hotel' costs), accounted for 30%, of the total and were lower than similar costs in industrialised nations. The largest contributory factors (median, range) towards total cost were, basic hospital charges (30%; 15 to 63%); theatre charges fixed (23%; 6 to 35%) and variable (14%; 8 to 27%); and anaesthetic charges (15%; 1 to 36%).

CONCLUSION

Cost reduction in patients undergoing surgery should focus on decreasing hospital stay, operating theatre time and anaesthetic expenditure. Although definite measures can be suggested from the study, further studies on these variables are necessary to optimise cost effectiveness of surgical units.

[Cost of anaesthesia at the university hospital]

BACKGROUND

The costs of anaesthesia in Polish hospitals are usually calculated as a percentage of the cost of the surgical procedure, or as a percentage of the total cost of the operating theatre. These methods cannot be accurate, since they do not take into consideration, the specifics of anaesthesia. Therefore, a new method of calculation, based of the actual use of materials and manpower, has been introduced in our institution.

METHODS

Anaesthesia procedures were divided into nine categories, according to risk of anaesthesia, type of surgery, type of anaesthesia, and working hours of the anaesthetic personnel. Each category was priced in points which expressed the actual value of the service provided, and the resulting totals were allocated to surgical specialties.

RESULTS

The costs of anaesthesia calculated by the new method differed markedly from previous calculations. The number of anaesthetics between 2008 and 2010 increased by 20%, while the cumulative costs of anaesthesia rose by only 13%, when compared to the previous method of calculation. Changes in anaesthesia costs, in various surgical specialties, varied from -49% to +65%, and were not related to the number of procedures.

CONCLUSION

The new scoring system made it possible to calculate actual anaesthesia costs in various surgical specialties. It is logical and practical and merits recommendation.

[Pharmacoeconomics: basic concepts and applications to clinical anesthesia]

The economic evaluation of medications and health care technology has gained importance in recent years. Health care resources are limited and their use must be optimized so that we can take the greatest possible advantage. Pharmacoeconomics seeks to analyze the best therapeutic drug choices to obtain the desired outcome in specific cases or in populations. The 4 approaches used in pharmacoeconomics are cost-minimization analysis, cost-benefit analysis, cost-effectiveness analysis, and cost-utility analysis. This review examines the characteristics of each type of study using examples from anesthesiology, a field in which pharmacoeconomics is beginning to play a role.

4 decisions that can affect your anesthesia subsidy

Four key considerations can affect the size of an anesthesia subsidy: Staffing models. The fair market value compensation for clinicians. The type of provider the organization needs. The payment approach for management of anesthesia services.

[Ambulatory anaesthesia, beneficial for children]

The advantages of ambulatory surgery and anaesthesia are widely recognised. Apart from their interest in terms of reducing hospital costs, they are overwhelmingly preferred by patients. Of all patients, it is children who can benefit the most.

Anesthesia subsidies: a strategic approach for financial executives

Healthcare financial executives should employ a systematic approach to anesthesia contract negotiations that: Establishes costs and considers alternative options to reduce anesthesia expense. Defines expected value. Aligns compensation Defines performance parameters. Establishes tracking metrics.

Financial and operational analysis of non-operating room anesthesia: the wrong way versus the right way

Most financial analysis regarding the cost of non-operating room anesthesia in hospitals is incorrect. This article indicates why this situation exists and suggests how to perform the cost analysis in the right way. It also reviews financial and operational strategies that can result in more efficient scheduling of anesthesia, thereby freeing up anesthesiologist time in the main operating room for non-operating room needs.

Interaction between anesthesia technology innovators, manufacturers, and purchasers

Levels of public and private funding for anesthesia services and health research reflect their value to the patient, the payor, and society. Improvements in anesthesia depend heavily on technologic advances. This article presents practical realistic assessment of medical innovation and barriers to its commercialization. Innovation by either academia or industry working in isolation is not possible. Innovation, education, and commercialization are interdependent and contribute to medical progress only when applied as a whole. Subordinating productive relationships between anesthesiologists and industry representatives to concerns of conflict of interest potentially puts diminishes the value of medical services, including anesthesia.

The value proposition of anesthesia information management systems

Anesthesia information management systems add value to the anesthesiologist and the hospital above that which is provided by manual anesthesia records. The more complete documentation and less biased recording of vital signs in this system, relative to manual records, provide data needed for quality initiatives and operating room management and for clinical research. The system can improve the ability to increase anesthesia charge capture, meet the requirements of pay-for-performance programs, and assist in the defense of malpractice allegations. Realization of value from the anesthesia information management systems requires additional expenditures of resources to adapt the systems to meet specific institutional requirements.

[Calculation of staffing requirements in anesthesia]

Historically, calculation of staffing requirements for anesthesia has developed from index numbers derived from the workplace method to the service performance method (XX time). The DRG revenues result from an average calculation of costs that results from an assumed calculation of staffing requirements based on the service performance method. In contrast to the principle of full cost coverage, a much stronger process orientation is needed under the conditions of the DRG system. When calculating personnel needs this process orientation also requires that it be oriented to the organization by differentiating between theater-related and non-theater-related anesthesiological services. In a second step the services rendered in a specified organization are then assessed for efficiency and if necessary optimized. Just as it applies to the whole clinical center, in departments of anesthesiology DRG revenues should be brought in line with the actual costs.

[Wastage of anesthetic related drugs in a university hospital]

BACKGROUND

The cost of wasted anesthetic related agents has not been clear in Japanese hospitals. We investigated whether the trainees in anesthesiology influence the cost of wasted anesthetic related agents.

METHODS

Investigation was carried out at the University of Tokyo Hospital. We interviewed each trainee in anesthesiology about all prepared anesthetic drugs and wasted ones at the end of each anesthetic management.

RESULTS

The percentage of wasted ampoules of anesthetic related agents was 15.85%, but the percentage of wasted cost was 5.15%. A large difference was not observed in transition of training period, and this percentage was not improved by training. We considered that this wasted cost is within permissible ranges in comparison with other reports.

CONCLUSIONS

During the training it is also important to develop a sense of medical economics.

An investigation into the practices of dairy producers and veterinarians in dehorning dairy calves in Ontario

The objective of this survey was to describe the current state of dehorning practices by dairy producers and veterinarians in Ontario and to identify opportunities to improve on existing practices. Two hundred and seven producers and 65 veterinarians completed a survey on dehorning practices during the summer of 2004. Seventy-eight percent of dairy producers dehorn their own calves; 22% use local anesthetics. Veterinarians dehorn calves for 31% of dairy clients; 92% use local anesthetics. Pain management was the most common reason for use of local anesthetics for both groups, while time (veterinarians) and time and cost (producers) were the most common reasons for lack of use. Producers who used local anesthetics were 6.5 times more likely to have veterinary involvement in their dehorning decisions. Thirteen percent of producers were unaware of the options for pain management. These results suggest that veterinarians should take the initiative to educate their clients about the options for pain management.

[Realisation of material costs in anaesthesia. Alternatives to the reimbursement via diagnosis-related groups]

BACKGROUND AND GOAL

For reimbursement via diagnosis-related groups (DRG), lump compensation-based payment of medical cases in German hospitals requires a case-related measuring and billing of resources that has to be consistent with DRG guidelines. Only through this, can the real costs be compared with the standard costs as calculated by the hospital reimbursment system (InEK) on a case-related basis and the DRG-specific break-even level be identified.

METHODS

In the present paper the authors introduce and validate two newly created alternative methods for case-related allocation of material costs in the field of anaesthesia. Method 1 allows online documentation of material costs via pre-defined anaesthesia standards. This full cost method is suitable for hospitals that have implemented an electronic hospital information system in their daily clinical documentation routine. For other hospitals method 2 could be applicable as the case-related allocation of material costs is done retrospectively based on the data collected in an electronic anaesthesia protocol record system (andoc, medlinq).

RESULTS

Method 1 makes it possible to allocate 90.3% of anaesthesia-related material costs to a specific case corresponding to a Pearsson coefficient of 0.77. After iterative improvement through optimisation of modules the documentation quality could be raised to >98% and a Pearsson coefficient of 0.96. Although the expense for implementation and maintenance is considerable, the necessary documentation work for the clinician is low. Method 2 demands no further clinical effort in documentation and implementation and 49.1% of all material costs can be assigned on a case-related basis.

CONCLUSIONS

The online documentation of material costs via predefined anaesthesia standards accounts for nearly all material costs in anaesthesia and only a negligible documentation effort is necessary for the clinician. Nevertheless, a complex and time-consuming configuration of standards and a continuous iterative alignment of the modules with the actual processes are required. Due to its process-orientated character, method 1 can also be used for workflow optimisation in terms of standard operating procedures (SOPs). Allocation of material costs with data from the electronic anaesthesia record system is a method that can be easily implemented but only a partial case relation is rendered possible.

Economic impact of cancellous bone grafting in trauma surgery

INTRODUCTION

Cancellous bone grafting is currently the most frequent method for replacement of bone material. In recent years, several alternative methods came into practice. However, up to now it remains unclear whether cancellous bone grafting is cheaper as compared to these new methods. Therefore, the aim of this study was to calculate the direct costs of cancellous bone grafting.

MATERIALS AND METHODS

For calculation of the direct costs operation time needed in addition to the main surgical intervention was measured and the material used recorded in a consecutive series of 50 interventions including bone grafting at the Department of Trauma Surgery at the University Hospital of Bonn Medical School. Surgical staff costs were calculated on the basis of a standard team consisting of one surgical attendant, surgical resident, surgical nurse, and nurse's service. Cost of anaesthesia was calculated on a per minute base.

RESULTS

Mean additional operation time was 26.3 min (range 17-35 min). Surgical staff costs per operation minute were 2.70 Euro, costs for anaesthesiological service were 4.18 Euro/min. Material additional used consisted of sutures and sterilization costs. Material costs summed up to 32.01 Euro. The total direct costs of bone grafting were 212.95 Euro.

CONCLUSION

The direct costs of harvesting cancellous bone graft and the use of bone replacement material are comparable. Due to the high complication rate at the donor site the total-cost-of-illness might be higher when using autologous bone graft.

[The problems with parallel narcosis. Professional and legal limits of delegation of anaesthesiological responsibilities to non-medical personnel]

The increasing mechanisation, specialisation and sub-specialisation in medicine have enduringly supported the delegation of originally medical activities to non-medical personnel and sometimes also made it necessary. Economical considerations have recently given additional impulse to these developments. It is indisputable that medical activities can be delegated to assistant personnel, however, it is equally indisputable that within the scope of the total spectrum of medical activities, there are limits to the extent of delegation, i.e. activities reserved exclusively for medical doctors. These include, by consensus of opinion, the physical examination, diagnosis, assessment of indication, determination of the therapy plan and informing the patient. The following article justifies from professional and legal viewpoints why anaesthesia also belongs to the genuine medical duties and is reserved exclusively for medical personnel. Therefore, the correct performance of parallel narcosis is coupled with far-reaching liability risks for all participants involved in this form of organisation or those responsible for them.

Electronic Reminders Improve Procedure Documentation Compliance and Professional Fee Reimbursement

BACKGROUND

Medicolegal, clinical, and reimbursement needs warrant complete and accurate documentation. We sought to identify and improve our compliance rate for the documentation of arterial catheterization in the perioperative setting.

METHODS

We first reviewed 12 mo of electronic anesthesia records to establish a baseline compliance rate for arterial catheter documentation. Residents and Certified Registered Nurse Anesthetists were randomly assigned to a control group and experimental group. When surgical incision and anesthesia end were documented in the electronic record keeper, a reminder routine checked for an invasive arterial blood pressure tracing. If a case used an arterial catheter, but no procedure note was observed, the resident or Certified Registered Nurse Anesthetist assigned to the case was sent an automated alphanumeric pager and e-mail reminder. Providers in the control group received no pager or e-mail message. After 2 mo, all staff received the reminders.

RESULTS

A baseline compliance rate of 80% was observed (1963 of 2459 catheters documented). During the 2-mo study period, providers in the control group documented 152 of 202 (75%) arterial catheters, and the experimental group documented 177 of 201 (88%) arterial lines (P < 0.001). After all staff began receiving reminders, 309 of 314 arterial lines were documented in a subsequent 2 mo period (98%). Extrapolating this compliance rate to 12 mo of expected arterial catheter placement would result in an annual incremental $40,500 of professional fee reimbursement.

CONCLUSIONS

The complexity of the tertiary care process results in documentation deficiencies. Inexpensive automated reminders can drastically improve compliance without the need for complicated negative or positive feedback.

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.

Operating Room Versus Office-Based Injection Laryngoplasty: A Comparative Analysis of Reimbursement

BACKGROUND

Injection laryngoplasty (IL) continues to evolve as new indications, techniques, approaches, and injection materials are developed. Although historically performed under local or general anesthesia in the operating room suite, IL is now increasingly being performed in an office-based setting. This report presents the results of a reimbursement analysis comparing office-based versus operative IL.

OBJECTIVE

The objective of this study was to compare the reimbursement of office-based injection laryngoplasty with the reimbursement of performing the same procedure in the operating room.

DESIGN

The authors conducted reimbursement and outcome analysis through retrospective office chart and hospital record review.

METHODS

A retrospective review was performed of the hospital records of patients having undergone injection laryngoplasty at the University of Pittsburgh Voice Center from July 1998 through March 2005. Group I included patients who underwent IL in the operating room, whereas group II included those who had office-based IL. A reimbursement analysis for both groups was then performed comparing surgeon fees, anesthesia, and hospital charges and reimbursement. The clinical efficacy of IL performed in either office versus operating room settings was measured by comparing the pre- and postintervention Voice Handicap Index-10 scores for all patients. A predictive model of potential cost savings is developed based on the results of the analysis.

RESULTS

Average reimbursement was 2,505 dollars for group I (n = 108) and 496 dollars for group II (n = 50). This reimbursement differential was preserved across the various insurance types examined. There was no significant difference in Voice Handicap Index-10 change after surgery between group I and II.

CONCLUSIONS

Office-based IL is both clinically and financially effective, providing patients with a convenient and flexible alternative to operating room-based intervention for glottal insufficiency.

Automated Documentation Error Detection and Notification Improves Anesthesia Billing Performance

Background

Documentation of key times and events is required to obtain reimbursement for anesthesia services. The authors installed an information management system to improve record keeping and billing performance but found that a significant number of their records still could not be billed in a timely manner, and some records were never billed at all because they contained documentation errors.

Methods

Computer software was developed that automatically examines electronic anesthetic records and alerts clinicians to documentation errors by alphanumeric page and e-mail. The software's efficacy was determined retrospectively by comparing billing performance before and after its implementation. Staff satisfaction with the software was assessed by survey.

Results

After implementation of this software, the percentage of anesthetic records that could never be billed declined from 1.31% to 0.04%, and the median time to correct documentation errors decreased from 33 days to 3 days. The average time to release an anesthetic record to the billing service decreased from 3.0+/-0.1 days to 1.1+/-0.2 days. More than 90% of staff found the system to be helpful and easier to use than the previous manual process for error detection and notification.

Conclusion

This system allowed the authors to reduce the median time to correct documentation errors and the number of anesthetic records that were never billed by at least an order of magnitude. The authors estimate that these improvements increased their department's revenue by approximately $400,000 per year.

[Monitoring the depth of anaesthesia: why, how and at which cost?]

The precise titration of anaesthetic agents is necessary to avoid the consequences of a too light depth of anaesthesia such as unexpected intraoperative awareness, as well as a too deep level of anaesthesia, which can be deleterious in terms of postoperative morbidity and mortality. The clinical evaluation of the depth of anaesthesia is poorly sensitive and specific. It does not permit to distinguish between pharmacodynamic components of anaesthesia. Several paraclinical depth of anaesthesia indices are currently available. Most of them are mainly designed to monitor the depth of the hypnotic component of anaesthesia. Their calculation is mostly based on the mathematical analysis of the electroencephalogram. They are efficient at reducing the incidence of unexpected intraoperative awareness, adjusting anaesthetic depth at an individual scale, predicting the time needed for recovery, allowing early extubation of patients, reducing their length of stay in the post anaesthesia care unit, and limiting the number of episodes of peroperative over and under dosage of anaesthetic agents. The knowledge of conditions that may impede the accurate interpretation of those indices is mandatory for an optimal use. Although undoubtedly beneficial for the patients, the use of those monitors is frequently responsible for supplementary' costs, particularly when the procedure is short.

[Professional teeth cleaning is more than plaque removal]

Telephone enquiries about the cost of cleaning the teeth of cats or dogs cannot be answered without clinical investigation of the animal and oral examination under sedation or anaesthesia. This article describes the procedures used during the professional cleaning of the teeth of companion animals. An itemized list of procedures and their cost means that the era of "shopping around" for teeth cleaning is past.

Do race, gender, and source of payment impact on anesthetic technique for inguinal hernia repair?

STUDY OBJECTIVE

To evaluate the potential differences in the type of anesthesia provided to patients of different race, gender, and source of payment undergoing inguinal hernia repair (IHR).

DESIGN

Retrospective cohort study.

SETTING

Ambulatory surgical centers/National Survey of Ambulatory Surgery.

PATIENTS

5810 patients older than 14 years who underwent IHR in an ambulatory surgical center.

INTERVENTIONS

Inguinal hernia repair under different types of anesthesia.

MEASUREMENTS

The association of race, gender, and source of payment with different types of anesthesia for IHR as determined by multivariate regression analysis.

RESULTS

Significant discrepancies in the use of various anesthetics between patients of different race, gender, and source of payment were found. Patients identified as black and those of other minority groups were significantly more likely to receive general anesthesia compared with those identified as white (odds ratio [OR] 2.76, confidence interval [CI] 1.96-3.88 and OR 1.66, CI 1.14-2.42, respectively). Those identified as black were less likely to receive epidural anesthesia compared with their white counterparts (OR 0.36, CI 0.14-0.95). Women were less likely than men to undergo IHR with epidural anesthesia (OR 0.5, 95% CI 0.3-0.85).

CONCLUSION

Significant discrepancies in the use of various anesthetics for IHR between patients of different race, gender, and insurance status were found. Despite limitations inherent to secondary data analysis, the findings raise the possibility that nonmedical factors may influence anesthetic management.

Development of a Module for Point-of-care Charge Capture and Submission Using an Anesthesia Information Management System

Background

The use of electronic charge vouchers in anesthesia practice is limited, and the effects on practice management are unreported. The authors hypothesized that the new billing technology would improve the effectiveness of the billing interface and enhance financial practice management measures.

Methods

A custom application was created to extract billing elements from the anesthesia information management system. The application incorporates business rules to determine whether individual cases have all required elements for a complete and compliant bill. The metrics of charge lag and days in accounts receivable were assessed before and after the implementation of the electronic charge voucher system.

Results

The average charge lag decreased by 7.3 days after full implementation. The total days in accounts receivable, controlling for fee schedule changes and credit balances, decreased by 10.1 days after implementation, representing a one-time revenue gain equivalent to 3.0% of total annual receipts. There are additional ongoing cost savings related to reduction of personnel and expenses related to paper charge voucher handling.

Conclusions

Anesthesia information management systems yield financial and operational benefits by speeding up the revenue cycle and by reducing direct costs and compliance risks related to the billing and collection processes. The observed reductions in charge lag and days in accounts receivable may be of benefit in calculating the return on investment that is attributable to the adoption of anesthesia information management systems and electronic charge transmission.
