From Listening to Action: Academic Surgical Departmental Response to Social Injustice Through Curricular Development.

OBJECTIVE: The aim of this study was to describe the development and evaluation of a structured department wide cultural competency curriculum. SUMMARY BACKGROUND DATA: Despite numerous organizational policies and statements, social injustice and bias still exist. Our department committed to assist individuals of the entire department to develop foundational knowledge and skills to combat implicit bias and systemic racism through the creation of a cultural competency curriculum. The purpose of this manuscript is to detail our curriculum and the evaluation of its effectiveness. METHODS: Using a well-established curriculum development framework, a cultural competency curriculum was developed focusing on knowledge, skills and attitudes at the individual level, for all members of the department. The curriculum was implemented through 6-hour-long sessions over a 9-week period. Effectiveness was assessed through a post curriculum survey. RESULTS: Twenty percent of the respondents had experienced bias based on race, ethnicity, or sexual orientation in the past 12 months, whereas 30% had experienced bias based on sex. Seventy-one percent independently explored related topics. The curriculum was overall well received and generally achieved the goals and objectives. CONCLUSION: Using a standard curriculum development framework, an effective department-wide cultural competency curriculum can be developed and implemented.

Expansion of Surgical Graduate Medical Education Training Programs: A Return on Investment Analysis.

BACKGROUND: The productivity of surgical departments is limited by the staffing of attending surgeons as well as surgical residents. Despite ongoing surgeon shortages, many health care organizations have been reluctant to expand training programs because of concerns about cost. We sought to determine the return on investment for the expansion of surgical training programs within our health system. METHODS: This study was completed as a retrospective review comparing two independent surgical departments at separate hospitals within a single integrated health system, including complete fiscal information from 2012 to 2019. Hospital A is a 594-bed hospital with large growth in its graduate surgical training programs over the study's period, whereas Hospital B is a 320-bed hospital where there was no expansion in surgical education initiatives. Case volumes, the number of full-time employees (FTE), and revenue data were obtained from our health systems business office. The number of surgical trainees, including general surgery residents and vascular surgery fellows, was provided by our office of Graduate Medical Education. The average yearly net revenue per surgeon was calculated for each training program and hospital location. RESULTS: Our results indicate a positive association between the number of surgical trainees and departmental net revenue, as well as the annual revenue generated per physician FTE. Each additional ancillary provider per physician FTE resulted in a positive impact of $112,552-$264,003 (R2 of 0.69 to 0.051). CONCLUSIONS: Regardless of hospital location or surgical specialty, our results demonstrate a positive association between the average net revenue generated per surgeon and the number of surgical trainees supporting the department. These findings are novel and provide evidence of a positive return on investment when surgical training programs are expanded.

How efficient are surgical treatments in Japan? The case of a high-volume Japanese hospital.

Japan's healthcare expenditures, which are largely publicly funded, have been growing dramatically due to the rapid aging of the population as well as the innovation and diffusion of new medical technologies. Annual costs for surgical treatments are estimated to be approximately USD 20 billion. Using unique longitudinal clinical data at the individual surgeon level, this study aims to estimate the technical efficiency of surgical treatments across surgical specialties in a high-volume Japanese teaching hospital by employing stochastic frontier analysis (SFA) with production frontier models. We simultaneously examine the impacts of potential determinants that are likely to affect inefficiency in operating rooms. Our empirical results show a relatively high average technical efficiency of surgical production, with modest disparity across surgical specialties. We also demonstrate that an increase in the number of operations performed by a surgeon significantly reduces operating room inefficiency, whereas the revision of the fee-for-service schedule for surgical treatments does not have a significant impact on inefficiency. In addition, we find higher technical efficiency among surgeons who perform multiple daily surgeries than those who perform a single operation in a day. We suggest that it is important for hospital management to retain efficient surgeons and physicians and provide efficient healthcare services given the competitive Japanese healthcare market.

General surgery in Canada: current scope of practice and future needs.

BACKGROUND: The scope of practice of general surgeons in Canada is highly variable. The objective of this study was to examine the demographic characteristics of general surgeons in Canada and compare surgical procedures performed across community sizes and specialties. METHODS: Data from the Canadian Institute for Health Information's National Physician Database were used to analyze fee-for-service (FFS) care provided by general surgeons and other providers across Canada in 2015/16. RESULTS: Across 8 Canadian provinces, 1669 general surgeons provided FFS care. The majority of the surgeons worked in communities with more than 100 000 residents (71%), were male (78%), were aged 35-54 years (56%) and were Canadian medical graduates (76%). Only 7% of general surgeons practised in rural areas and 14% in communities with between 10 000 and 50 000 residents. Rural communities were significantly more likely to have surgeons who were international medical graduates or who were older than 65 years. The surgical procedures most commonly performed by general surgeons were hernia repairs, gallbladder and biliary tree surgery, excision of skin tumours, colon and intestine resections and breast surgery. Many general surgeons performed procedures not listed in their Royal College of Physicians and Surgeons of Canada training objectives. CONCLUSION: Canadian general surgeons provide a wide array of surgical services, and practice patterns vary by community size. Surgeons practising in rural and small communities require proficiency in skills not routinely taught in general surgery residency. Opportunities to acquire these skills should be available in training to prepare surgeons to meet the care needs of Canadians.

CONTEXTE: La pratique des chirurgiens généralistes au Canada varie grandement. Cette étude visait à examiner les caractéristiques démographiques des chirurgiens généralistes au Canada et à comparer les interventions réalisées selon la spécialité et la taille des collectivités. MÉTHODES: Des données de la Base de données nationale sur les médecins de l'Institut canadien d'information sur la santé ont été utilisées pour analyser les soins rémunérés à l'acte dispensés par des chirurgiens généralistes et d'autres fournisseurs de soins au Canada en 2015­2016. RÉSULTATS: Dans 8 provinces canadiennes, 1669 chirurgiens généralistes ont fourni des soins rémunérés à l'acte. La majorité d'entre eux travaillaient dans des collectivités de plus de 100 000 résidents (71 %), étaient des hommes (78 %), avaient entre 35 et 54 ans (56 %) et avaient obtenu leur diplôme de médecine au Canada (76 %). Seuls 7 % des chirurgiens généralistes travaillaient en région rurale et 14 %, dans des collectivités comptant entre 10 000 et 50 000 résidents. En région rurale, la probabilité que les chirurgiens soient des diplômés internationaux en médecine ou aient plus de 65 ans était significativement plus élevée. Les interventions les plus fréquentes étaient la réparation d'une hernie, la chirurgie de la vésicule biliaire et des voies biliaires, le retrait de tumeurs de la peau, la résection du côlon ou de l'intestin et la chirurgie mammaire. De nombreux chirurgiens généralistes ont réalisé des procédures ne faisant pas partie des objectifs de formation du Collège royal des médecins et chirurgiens du Canada. CONCLUSION: Les chirurgiens généralistes canadiens réalisent une large gamme d'interventions chirurgicales et leur pratique varie selon la taille de la collectivité dans laquelle ils travaillent. Les chirurgiens exerçant en milieu rural et dans les petites collectivités doivent avoir des compétences qui ne sont habituellement pas enseignées durant la résidence en chirurgie générale. La formation devrait intégrer des occasions d'acquérir ces compétences pour préparer les chirurgiens à répondre aux besoins en matière de soins des Canadiens.

Skin Cancer Excision Is More Efficient and Cost Effectivein a Specialist Secondary Care Service.

Aim To compare the relative efficiencies of skin excisions in primary and secondary care. Methods We compared the benign: malignant ratio for specimens referred by General Practice, General Surgery and the Skin Cancer Service to the regional pathology laboratory over one month. We used cost minimization analysis to compare the relative efficiencies of the services. Results 620 excisions were received: 139 from General Practice, 118 from General Surgery and 363 from the Skin Cancer Service. The number (%) of malignant lesions was 13 (9.4%) from General Practice, 18 (15.2%) from General Surgery and 137 (37.7%) from the Skin Cancer Service. Excision was cheaper in General Practice at €84.58 as compared to €97.49 in the hospital day surgical unit. However, the cost per malignant lesion excised was €1779.80 in general practice versus €381.78 in the Skin Cancer Service. Conclusion Our results indicate that moving skin cancer treatment to General Practice may result in an excess of benign excisions and therefore be both less efficient and less cost effective.

Cost Burden and Mortality in Rural Emergency General Surgery Transfer Patients.

BACKGROUND: Recent articles have suggested regionalization of some emergency general surgery (EGS) problems to tertiary referral centers. We sought to characterize the clinical and cost burden of such transfers to our tertiary referral center. MATERIALS AND METHODS: Data were collected retrospectively for nine EGS diagnoses for patients admitted to the EGS service during calendar years 2015 and 2016. Patients were grouped as inpatient transfers (IPTs), Emergency Department transfers (EDTs), or local admissions (LAs). Demographic data, length of stay at originating site, insurance status, Charlson Comorbidity Index, and all relevant financial data were obtained. RESULTS: Six hundred sixty-three patients were reviewed: 93 IPTs, 343 EDTs, and 227 LAs. IPTs required longer lengths of stay (7.0 d compared to 4.0 d for EDTs and 3.0 d for LAs), higher median direct costs, and higher case mix index, which produced a higher median revenue but averaged a median net loss (-$264 compared to +$2436 for EDTs and +$3125 for LAs). The IPTs had higher median comorbidities (Charlson Comorbidity Index 3.5 versus 2.9 for EDTs and 2.0 for LAs), age (62 y versus 58 for EDTs and 52 for LAs), and mortality rate (7.5% versus 2.3% for EDTs and 0.4% for LAs). CONCLUSIONS: Patients who present to a tertiary care EGS service as an IPT from another hospital have more comorbidities, higher mortality rate, and result in a financial loss. These data suggest the need for adequate risk adjustment in quality assessment of tertiary referral center outcomes and the need for increased financial reimbursement for the care of these patients.

Savings from reducing low-value general surgical interventions.

BACKGROUND: Finding opportunities for improving efficiency is important, given the pressure on national health budgets. Identifying and reducing low-value interventions that deliver little benefit is key. A systematic literature evaluation was done to identify low-value interventions in general surgery, with further assessment of their cost. METHODS: A multiplatform method of identifying low value interventions was undertaken, including a broad literature search, a targeted database search, and opportunistic sampling. The results were then stratified by impact, assessing both frequency and cost. RESULTS: Seventy-one low-value general surgical procedures were identified, of which five were of high frequency and high cost (highest impact), 22 were of high cost and low frequency, 23 were of low cost and high frequency, and 21 were of low cost and low frequency (lowest impact). Highest impact interventions included inguinal hernia repair in minimally symptomatic patients, inappropriate gastroscopy, interval cholecystectomy, CT to diagnose appendicitis and routine endoscopy in those who had CT-confirmed diverticulitis. Their estimated cost was €153 383 953. CONCLUSION: Low-value services place a burden on health budgets. Stopping only five high-volume, high-cost general surgical procedures could save the National Health Service €153 million per annum.

Action observation for sensorimotor learning in surgery.

BACKGROUND: Acquiring new motor skills to learn complex movements and master the use of a diverse range of instruments is fundamental for developing expertise in surgery. Although aspects of skill development occur through trial and error, watching the performance of another individual (action observation) is an increasingly important adjunct for the acquisition of these complex skills before performing a procedure. The aim of this review was to examine the evidence in support of the use of action observation in surgery. METHODS: A narrative review of observational learning for surgical motor skills was undertaken. Searches of PubMed and PsycINFO databases were performed using the terms 'observational learning' OR 'action observation' AND 'motor learning' OR 'skill learning'. RESULTS: Factors such as the structure of physical practice, the skill level of the demonstrator and the use of feedback were all found to be important moderators of the effectiveness of observational learning. In particular, observation of both expert and novice performance, cueing attention to key features of the task, and watching the eye movements of expert surgeons were all found to enhance the effectiveness of observation. It was unclear, however, whether repeated observations were beneficial for skill learning. The evidence suggests that these methods can be employed to enhance surgical training curricula. CONCLUSION: Observational learning is an effective method for learning surgical skills. An improved understanding of observational learning may further inform the refinement and use of these methods in contemporary surgical training curricula.

"I got it on Ebay!": cost-effective approach to surgical skills laboratories.

BACKGROUND: Surgical education is witnessing a surge in the use of simulation. However, implementation of simulation is often cost-prohibitive. Online shopping offers a low budget alternative. The aim of this study was to implement cost-effective skills laboratories and analyze online versus manufacturers' prices to evaluate for savings. MATERIALS AND METHODS: Four skills laboratories were designed for the surgery clerkship from July 2014 to June 2015. Skills laboratories were implemented using hand-built simulation and instruments purchased online. Trademarked simulation was priced online and instruments priced from a manufacturer. Costs were compiled, and a descriptive cost analysis of online and manufacturers' prices was performed. Learners rated their level of satisfaction for all educational activities, and levels of satisfaction were compared. RESULTS: A total of 119 third-year medical students participated. Supply lists and costs were compiled for each laboratory. A descriptive cost analysis of online and manufacturers' prices showed online prices were substantially lower than manufacturers, with a per laboratory savings of: $1779.26 (suturing), $1752.52 (chest tube), $2448.52 (anastomosis), and $1891.64 (laparoscopic), resulting in a year 1 savings of $47,285. Mean student satisfaction scores for the skills laboratories were 4.32, with statistical significance compared to live lectures at 2.96 (P < 0.05) and small group activities at 3.67 (P < 0.05). CONCLUSIONS: A cost-effective approach for implementation of skills laboratories showed substantial savings. By using hand-built simulation boxes and online resources to purchase surgical equipment, surgical educators overcome financial obstacles limiting the use of simulation and provide learning opportunities that medical students perceive as beneficial.

Adoption of robotics in a general surgery residency program: at what cost?

BACKGROUND: Robotic technology is increasingly being utilized by general surgeons. However, the impact of introducing robotics to surgical residency has not been examined. This study aims to assess the financial costs and training impact of introducing robotics at an academic general surgery residency program. METHODS: All patients who underwent laparoscopic or robotic cholecystectomy, ventral hernia repair (VHR), and inguinal hernia repair (IHR) at our institution from 2011-2015 were identified. The effect of robotic surgery on laparoscopic case volume was assessed with linear regression analysis. Resident participation, operative time, hospital costs, and patient charges were also evaluated. RESULTS: We identified 2260 laparoscopic and 139 robotic operations. As the volume of robotic cases increased, the number of laparoscopic cases steadily decreased. Residents participated in all laparoscopic cases and 70% of robotic cases but operated from the robot console in only 21% of cases. Mean operative time was increased for robotic cholecystectomy (+22%), IHR (+55%), and VHR (+61%). Financial analysis revealed higher median hospital costs per case for robotic cholecystectomy (+$411), IHR (+$887), and VHR (+$1124) as well as substantial associated fixed costs. CONCLUSIONS: Introduction of robotic surgery had considerable negative impact on laparoscopic case volume and significantly decreased resident participation. Increased operative time and hospital costs are substantial. An institution must be cognizant of these effects when considering implementing robotics in departments with a general surgery residency program.

Cost-Effectiveness in Global Surgery: Pearls, Pitfalls, and a Checklist.

INTRODUCTION: Cost-effectiveness analysis can be a powerful policy-making tool. In the two decades since the first cost-effectiveness analyses in global surgery, the methodology has established the cost-effectiveness of many types of surgery in low- and middle-income countries (LMICs). However, with the crescendo of cost-effectiveness analyses in global surgery has come vast disparities in methodology, with only 15% of studies adhering to published guidelines. This has led to results that have varied up to 150-fold. METHODS: The theoretical basis, common pitfalls, and guidelines-based recommendations for cost-effectiveness analyses are reviewed, and a checklist to be used for cost-effectiveness analyses in global surgery is created. RESULTS: Common pitfalls in global surgery cost-effectiveness analyses fall into five categories: the analytic perspective, cost measurement, effectiveness measurement, probability estimation, valuation of the counterfactual, and heterogeneity and uncertainty. These are reviewed in turn, and a checklist to avoid these pitfalls is developed. CONCLUSION: Cost-effectiveness analyses, when done rigorously, can be very useful for the development of efficient surgical systems in LMICs. This review highlights the common pitfalls in these analyses and methods to avoid these pitfalls.

Tutorial Assistance for Board Certification in Surgery: Frequency, Associated Time and Cost.

BACKGROUND: Tutorial assistance is related to extra time and cost, and the hospitals' financial compensation for this activity is under debate. We therefore aimed at quantifying the extra time and resulting cost required to train one surgical resident in the operating theatre for board certification in Switzerland as an example of a training curriculum involving several surgical subspecialties. Additionally, we intended to quantify the percentage of tutorial assistance. METHODS: We analysed 200,700 operations carried out between 2008 and 2012. Median duration of procedure categories was calculated according to four different seniority levels. The extra time if the procedure was performed by residents, and resulting cost were analysed. The percentage of procedures carried out by residents as compared to more experienced surgeons was assessed over time. RESULTS: On average, residents performed about a third of all operations including typical teaching procedures like appendectomies. An increase in duration and cost of well-defined procedures categories, e.g. cholecystectomies was demonstrated if a resident performed the procedure. In less well-defined categories, residents seemed to perform less difficult procedures than senior consultants resulting in shorter durations of surgery. CONCLUSIONS: The financial impact of tutorial assistance is important, and solutions need to be found to compensate for this activity. The low percentage of procedures performed by trainees may make it difficult to fulfil requirements for board certification within a reasonable period of time. This should be addressed within the training curriculum.

The Association of Frailty With Outcomes and Resource Use After Emergency General Surgery: A Population-Based Cohort Study.

BACKGROUND: Older patients undergoing emergency general surgery (EGS) experience high rates of postoperative morbidity and mortality. Studies focused primarily on elective surgery indicate that frailty is an important predictor of adverse outcomes in older surgical patients. The population-level effect of frailty on EGS is poorly described. Therefore, our objective was to measure the association of preoperative frailty with outcomes in a population of older patients undergoing EGS. METHODS: We created a population-based cohort study using linked administrative data in Ontario, Canada, that included community-dwelling individuals aged >65 years having EGS. Our main exposure was preoperative frailty, as defined by the Johns Hopkins Adjusted Clinical Groups frailty-defining diagnoses indicator. The Adjusted Clinical Groups frailty-defining diagnoses indicator is a binary variable that uses 12 clusters of frailty-defining diagnoses. Our main outcome measures were 1-year all-cause mortality (primary), intensive care unit admission, length of stay, institutional discharge, and costs of care (secondary). RESULTS: Of 77,184 patients, 19,779 (25.6%) were frail. Death within 1 year occurred in 6626 (33.5%) frail patients compared with 11,366 (19.8%) nonfrail patients. After adjustment for sociodemographic and surgical confounders, this resulted in a hazard ratio of 1.29 (95% confidence interval [CI] 1.25-1.33). The risk of death for frail patients varied significantly across the postoperative period and was particularly high immediately after surgery (hazard ratio on postoperative day 1 = 23.1, 95% CI 22.3-24.1). Frailty was adversely associated with all secondary outcomes, including a 5.82-fold increase in the adjusted odds of institutional discharge (95% CI 5.53-6.12). CONCLUSIONS: After EGS, frailty is associated with increased rates of mortality, institutional discharge, and resource use. Strategies that might improve perioperative outcomes in frail EGS patients need to be developed and tested.

Providing anesthesia in resource-limited settings.

PURPOSE OF REVIEW: The article reviews the reality of anesthetic resource constraints in low and middle-income countries (LMICs). Understanding these limitations is important to volunteers from high-income countries who desire to teach or safely provide anesthesia services in these countries. RECENT FINDINGS: Recently published information on the state of anesthetic resources in LMICs is helping to guide humanitarian outreach efforts from high-income countries. The importance of using context-appropriate anesthesia standards and equipment is now emphasized. Global health experts are encouraging equal partnerships between anesthesia health care providers working together from different countries. The key roles that ketamine and regional anesthesia play in providing well tolerated anesthesia for cesarean sections and other common procedures is increasingly recognized. SUMMARY: Anesthesia can be safely given in LMICs with basic supplies and equipment, if the anesthesia provider is trained and vigilant. Neuraxial and regional anesthesia and the use of ketamine as a general anesthetic appear to be the safest alternatives in low-resource countries. Environmentally appropriate equipment should be encouraged and pulse oximeters should be in every anesthetizing location. LMICs will continue to need support from outside sources until capacity building has made more progress.

Industry Bias in Randomized Controlled Trials in General and Abdominal Surgery: An Empirical Study.

BACKGROUND: Industry sponsorship has been identified as a source of bias in several fields of medical science. To date, the influence of industry sponsorship in the field of general and abdominal surgery has not been evaluated. METHODS: A systematic literature search (1985-2014) was performed in the Cochrane Library, MEDLINE, and EMBASE to identify randomized controlled trials in general and abdominal surgery. Information on funding source, outcome, and methodological quality was extracted. Association of industry sponsorship and positive outcome was expressed as odds ratio (OR) with 95% confidence interval (CI). A χ test and a multivariate logistic regression analysis with study characteristics and known sources of bias were performed. RESULTS: A total of 7934 articles were screened and 165 randomized controlled trials were included. No difference in methodological quality was found. Industry-funded trials more often presented statistically significant results for the primary endpoint (OR, 2.44; CI, 1.04-5.71; P = 0.04). Eighty-eight of 115 (76.5%) industry-funded trials and 19 of 50 (38.0%) non-industry-funded trials reported a positive outcome (OR, 5.32; CI, 2.60-10.88; P < 0.001). Industry-funded trials more often reported a positive outcome without statistical justification (OR, 5.79; CI, 2.13-15.68; P < 0.001). In a multivariate analysis, funding source remained significantly associated with reporting of positive outcome (P < 0.001). CONCLUSIONS: Industry funding of surgical trials leads to exaggerated positive reporting of outcomes. This study emphasizes the necessity for declaration of funding source. Industry involvement in surgical research has to ensure scientific integrity and independence and has to be based on full transparency.

[Performance development of a university operating room after implementation of a central operating room management]. / Leistungsentwicklung eines universitären OP-Bereichs nach Implementierung eines zentralen OP-Managements.

The difficult financial situation in German hospitals requires measures for improvement in process quality. Associated increases in revenues in the high income field "operating room (OR) area" are increasingly the responsibility of OR management but it has not been shown that the introduction of an efficiency-oriented management leads to an increase in process quality and revenues in the operating theatre. Therefore the performance in the operating theatre of the University Medical Center Göttingen was analyzed for working days in the core operating time from 7.45 a.m. to 3.30 p.m. from 2009 to 2014. The achievement of process target times for the morning surgery start time and the turnover times of anesthesia and OR-nurses were calculated as indicators of process quality. The number of operations and cumulative incision-suture time were also analyzed as aggregated performance indicators. In order to assess the development of revenues in the operating theatre, the revenues from diagnosis-related groups (DRG) in all inpatient and occupational accident cases, adjusted for the regional basic case value from 2009, were calculated for each year. The development of revenues was also analyzed after deduction of revenues resulting from altered economic case weighting. It could be shown that the achievement of process target values for the morning surgery start time could be improved by 40 %, the turnover times for anesthesia reduced by 50 % and for the OR-nurses by 36 %. Together with the introduction of central planning for reallocation, an increase in operation numbers of 21 % and cumulative incision-suture times of 12% could be realized. Due to these additional operations the DRG revenues in 2014 could be increased to 132 % compared to 2009 or 127 % if the revenues caused by economic case weighting were excluded. The personnel complement in anesthesia (-1.7 %) and OR-nurses (+2.6 %) as well as anesthetists (+6.7 %) increased less compared to the revenues or were slightly reduced. This improvement in process quality and cumulative incision-suture times as well as the increase in revenues, reflect the positive impact of an efficiency-oriented central OR management. The OR management releases due to measures of process optimization the necessary personnel and time resources and therefore achieves the basic prerequisites for increased revenues of surgical disciplines. The method presented can be used by other hospitals as a guideline to analyze performance development.

[Can Topical Negative Pressure Therapy be Performed as a Cost-Effective General Surgery Procedure in the German DRG System?]. / Führt die Vakuumsaugtherapie tatsächlich zu einer Kosteneffektivität in der Allgemeinchirurgie im G-DRG-System?

INTRODUCTION: Topical negative pressure therapy (TNPT) has been established for surgical wound therapy with different indications. Nevertheless, there is only sparse evidence regarding its therapeutic superiority or cost-effectiveness in the German DRG system (G-DRG). This study was designed to analyse the cost-effectiveness of TNPT in the G-DRG system with a focus on daily treatment costs and reimbursement in a general surgery care setting. PATIENTS/MATERIALS AND METHODS: In this retrospective study, we included 176 patients, who underwent TNPT between 2007 and 2011 for general surgery indications. Analysis of the cost-effectiveness involved 149 patients who underwent a simulation to calculate the reimbursement with or without TNPT by a virtual control group in which the TNP procedure was withdrawn for DRG calculation. This was followed by a calculation of costs for wound dressings and TNPT rent and material costs. Comparison between the "true" and the virtual group enabled calculation of the effective remaining surplus per case. RESULTS: Total reimbursement by included TNPT cases was 2,323 ,70.04 €. Costs for wound dressings and TNPT rent were 102,669.20 €. In 41 cases there was a cost-effectiveness (27.5%) with 607,422.03 € with TNP treatment, while the control group without TNP generated revenues of 442,015.10 €. Costs for wound dressings and TNPT rent were 47,376.68 €. In the final account we could generate a cost-effectiveness of 6759 € in 5 years per 149 patients by TNPT. In 108 cases there was no cost-effectiveness (72.5%). CONCLUSION: TNPT applied in a representative general surgery setting allows for wound therapy without a major financial burden. Based on the costs for wound dressings and TNPT rent, a primarily medically based decision when to use TNPT can be performed in a balanced product cost accounting. This study does not analyse the superiority of TNPT in wound care, so further prospective studies are required which focus on therapeutic superiority and cost-effectiveness.

SOCIAL AND ECONOMIC ASPECTS OF SIMULTANEOUS OPERATIONS ON ABDOMINAL ORGANS.

The article presents an analysis of 107 cases of simultaneous operations of big volume with main stage as gastric resections (gastrectomy) or large intestine resections and mean volume interferences as cholecystectomy and removal of abdominal hernias. It was stated, that simultaneous operations compared with two steps treatment of combined surgical diseases obtained the high economical efficacy. This efficacy was determined by a single - stage routine presurgical examination, single anesthetic management, less medical expenses for medication and laboratory - instrumental studies in postoperative period, significant shortening the terms of hospitalization and disability terms. The authors proposed formulas to evaluate the economiс efficacy of simultaneous operations in system of paid medical service and system of rendering medical aid using paid medical insurance. The efficacy of large operations was 40 766 rubles and in case of mean volume interventions - 25 382 rubles for the paid medical system. The economical efficacy of simultaneous operations of large and mean volume was the same in the system of obligatory medical insurance. It consisted of 19 737,5 or 22 920,1 rubles and depended on the degree of operative anaesthetic risk of the second intervention in two steps treatment of patients.

Surgical Care and Health Systems.

BACKGROUND: While surgical care impacts a wide variety of diseases and conditions with non-operative and operative services, both preventive and curative, there has been little discussion concerning how surgery might be integrated within the health system of a low and middle-income country (LMIC), nor how strengthening surgical services may improve health systems and population health. METHODS: We reviewed reports from several meetings of the working group on health systems strengthening of the Global Initiative for Emergency and Essential Surgical Care, and also performed a review of the literature including the search terms "surgery," "health system," "developing country," "health systems strengthening," "health information system," "financing," "governance," and "integration." RESULTS: The literature search revealed no reports which focused on the integration of surgical services within a health system or as a component of health system strengthening. A conceptual model of how surgical care might be integrated within a health system is proposed, based on the discussions of our working group, combined with sources from the medical literature, and utilizing the World Health Organization's conceptual model of a health system. CONCLUSIONS: Strengthening the delivery of surgical services in LMICs will require inputs at multiple levels within a health system, and this effort will require the coalescence of committed individuals and organizations, supported by civil society.
