Dissecting a department of surgery: Exploring organizational culture and competency expectations.

INTRODUCTION: In order to recruit high-potential trainees, surgery residency and fellowship programs must first understand what competencies and attributes are required for success in their respective programs. This study performed a systematic analysis to define organizational culture and competency expectations across training programs within one academic surgery department. METHODS: Subject matter experts rated the importance and frequency of 22 competencies and completed a 44-item organizational culture inventory along 1 to 5 Likert-type scales. RESULTS: Importance and frequency attributions of competencies varied significantly among programs (p < .05 by ANOVA), but there was substantial agreement on organizational culture; self-directed (x̄ = 3.8), perfectionist (x̄ = 3.7) and social (x̄ = 3.7) attributes were most representative of the program, while oppositional (x̄ = 1.8), competitive (x̄ = 2.5) and hierarchical (x̄ = 2.7) characteristics were least representative. CONCLUSIONS: Residency and fellowship programs within the same department have shared perceptions of the culture and values of their institution, but seek different competencies among entering trainees.

A Prospective Assessment of Adverse Events in 3 Digestive Surgery Departments From Central Tunisia.

OBJECTIVE: The aim of the study was to prospectively assess the incidence, the preventability, and the factors contributing to adverse events (AEs) in surgical departments of Tunisian hospitals. METHODS: A prospective longitudinal study evaluated the incidence of AEs in surgical departments of three university hospitals in central Tunisia. The study followed 1687 admitted patients until their discharge from the hospitals based on a standard two-stage method that first included staff interviews and review of medical records based on 18 criteria and later was followed by an expert review to confirm or reject the presence of an AE. RESULTS: The overall incidence of AEs was 18.1% (95% confidence interval = 16.26-19.94), with an incidence density of 21.6 events per 1000 patient-days. The most frequent AEs were those related to operative procedures (34.9%) and to hospital-acquired infections (30.3%).The multivariate analysis shows that the proportion of AEs increased significantly with intrinsic risk factors (odds ratio [OR] = 2.51, P < 0.001), extrinsic risk factors (OR = 1.38, P = 0.02), length of stay of greater than 7 days (OR = 2.27, P < 0.001), and unplanned admissions (OR = 2.59, P < 0.01). Overall, the major consequences of suffering an AE were that 90% had a prolonged hospital stay, 6% had a permanent disability, and 4% encountered death. More than 60% of the identified AEs were considered to be preventable. CONCLUSIONS: Surgical AEs have a significant impact on patient outcomes in terms of length of stay, disability, and mortality, and a considerable proportion of them are preventable. Prospective studies provide better insight regarding AEs under circumstances where hospital records are not optimal. Patient safety programs led by qualified health professionals can reduce patient harm in surgical departments of hospitals in most situations.

[Improving Hospital efficiency: assessment of performance of a surgical suite through root cause analysis, in a hospital in northern Italy]. / Migliorare l'efficienza dell'ospedale. Valutazione della performance di un Blocco Operatorio attraverso l'applicazione della Root Cause Analysis (RCA).

A Surgical Suite (SS) is a complex system in which different healthcare professionals work. Inefficient management could lead to waste of money and time and reduce quality of care. The aim of the study was to carry out an organizational assessment of a SS in northern Italy, in order to identify weaknesses and inadequacies related to its performance and promote strategies to increase efficiency. The study was conducted by process mapping of the working context, qualitative and quantitative analysis of patient documents and an evaluation of the critical issues using the root cause analysis (RCA) tool. The Plan Do Check Act (PDCA) method was used to implement the necessary changes. A detailed description of the staff involved, medical devices available, organization and timing of the SS was performed. Inefficiencies in the unit were caused mainly by insufficient medical devices and underusage of the radiological software Picture Archiving and Communication System (PACS). Root causes of inefficiencies were identified and classified into four areas: organization/structure, personnel, technologies and methods. In particular, critical issues were identified in: the planning processes, the heterogeneity of technical and Information technology skills and educational background of nursing staff, the presence of several computerized information systems and lack of a connection interface between the different software, the lack of internal procedures and paths and lack of continuing professional education opportunities. Two multidisciplinary working tables were launched by the hospital management in order to identify improvement strategies. The evaluation allowed us to define the root causes of SS inefficiency in this hospital, leading to a reorganization with a view to continuous improvement. An innovative aspect of the present study was the use of RCA to perform an organizational assessment in healthcare, rather than as a reactive risk management tool.

Assessment of Avoidable Readmissions in a Visceral Surgery Department with an Algorithm: Methodology, Analysis and Measures for Improvement.

BACKGROUND: Standardized quality indicators assessing avoidable readmission become increasingly important in health care. They can identify improvements area and contribute to enhance the care delivered. However, the way of using them in practice was rarely described. METHODS: Retrospective study uses prospective inpatients' information. Thirty-day readmissions were deemed potentially avoidable or non-avoidable by a computerized algorithm, and annual rate was reported between 2010 and 2014. Observed rate was compared to expected rate, and medical record review of potentially avoidable readmissions was conducted on data between January and June 2014. RESULTS: During a period of ten semesters, 11,011 stays were screened by the algorithm and a potentially avoidable readmission rate (PAR) of 7% was measured. Despite stable expected rate of 5 ± 0.5%, an increase was noted concerning the observed rate since 2012, with a highest value of 9.4% during the first semester 2014. Medical chart review assessed the 109 patients screened positive for PAR during this period and measured a real rate of 7.8%. The delta was in part due to an underestimated case mix owing to sub-coded comorbidities and not to health care issue. CONCLUSIONS: The present study suggests a methodology for practical use of data, allowing a validated quality of care indicator. The trend of the observed PAR rate showed a clear increase, while the expected PAR rate was stable. The analysis emphasized the importance of adequate "coding chain" when such an algorithm is applied. Moreover, additional medical chart review is needed when results deviate from the norm.

Continuous improvement of safety in the Intensive Care and Surgical environment according to UNE 179003:2013 standard: 8 years experience. / Mejora continua de la seguridad en el ámbito de un Servicio de Anestesiología y Cuidados Intensivos a través de la certificación según la norma de UNE 179003:2013: 8 años de experiencia.

INTRODUCTION: The UNE 179003:2013 standard requires compliance with protocols to reduce the risks of patients from adverse events. METHODS: A description is presented of the procedure used in the Hospital Povisa to achieve UNE 179003:2010 certification for the intensive care unit, surgical division, and post-anaesthesia recovery unit (PARU). This was based on a risk management system, focusing on pro-active analysis using failure modes and effects analysis (FMEA) with the description of causes, consequences, risk weighting, and specific risk-minimising measures. A description is also presented of the analysis of reported adverse events (reactive analysis) in the Safety in Anesthesia and Resuscitation (SENSAR) notification system and the measures implemented over an eight-year period. RESULTS: The UNE 179003:2010 certification was obtained in July 2012, and the re-certification was achieved in July 2015. A total of 66 potential risks were established, which were weighted using a risk probability index (RPI), and measures were implemented that reduced this RPI by half. It also reflects the analysis of 1114 events declared in the SENSAR system over the past eight years, allowing for the introduction of 2681 measures, of which 98.4% are fully implemented. CONCLUSION: The application of the risk management methodology allowed (a) to improve safety in the area of action by reducing the risk to which the patients are subject, and (b) to gain certification in the UNE 179003 standard.

Making the pediatric perioperative surgical home come to life by leveraging existing health information technology.

PURPOSE OF REVIEW: To design a patient data dashboard for the Department of Anesthesiology, Perioperative and Pain Medicine at Boston Children's Hospital that supports care integration across the healthcare system as described by the pediatric perioperative surgical home (PPSH) initiative. RECENT FINDINGS: By using 360 Technology, patient data was automatically pulled from all available Electronic Health Record sources from 2005 to the present. The PPSH dashboard described in this report provides a guide for implementation of PPSH Clinical Care Pathways. The dashboard integrates several databases to allow for visual longitudinal tracking of patient care, outcomes, and cost. The integration of electronic information provided the ability to display, compare, and analyze selected PPSH metrics in real time. By utilizing the PPSH dashboard format the use of an automated, integrated clinical, and financial health data profile for a specific patient population may improve clinicians' ability to have a comprehensive assessment of all care elements. This more global clinical thinking has the potential to produce bottom-up, evidence-based healthcare reform. SUMMARY: The experience with the PPSH dashboard provides solid evidence for the use of integrated Electronic Health Record to improve patient outcomes and decrease cost.

Hospital Surgical Volumes and Mortality after Coronary Artery Bypass Grafting: Using International Comparisons to Determine a Safe Threshold.

OBJECTIVE: To estimate a safe minimum hospital volume for hospitals performing coronary artery bypass graft (CABG) surgery. DATA SOURCE: Hospital data on all publicly funded CABG in five European countries, 2007-2009 (106,149 patients). DESIGN: Hierarchical logistic regression models to estimate the relationship between hospital volume and mortality, allowing for case mix. Segmented regression analysis to estimate a threshold. FINDINGS: The 30-day in-hospital mortality rate was 3.0 percent overall, 5.2 percent (95 percent CI: 4.0-6.4) in low-volume hospitals, and 2.1 percent (95 percent CI: 1.8-2.3) in high-volume hospitals. There is a significant curvilinear relationship between volume and mortality, flatter above 415 cases per hospital per year. CONCLUSIONS: There is a clear relationship between hospital CABG volume and mortality in Europe, implying a "safe" threshold volume of 415 cases per year.

Escalation of care in surgery: a systematic risk assessment to prevent avoidable harm in hospitalized patients.

OBJECTIVE: To systematically risk assess and analyze the escalation of care process in surgery so as to identify problems and provide recommendations for intervention. BACKGROUND: The ability to escalate care appropriately when managing deteriorating patients is a hallmark of surgical competence and safe postoperative care. Healthcare-Failure-Mode-Effects-Analysis (HFMEA) is a methodology adapted from safety-critical industries, which allows for hazardous process failures to be prospectively identified and solutions to be recommended. METHODS: Forty-two hours of ethnographic observations on surgical wards in 3 London hospitals (phase 1) formed the basis of an escalation process diagram. A risk-assessment survey identified failures associated with process steps and attributed hazard scores (phase 2). Patient safety and clinical risk experts validated hazard scores through a group consensus meeting (phase 3). Hazardous failures were taken forward to multidisciplinary HFMEA where cause analysis was applied and interventions were recommended (phase 4). RESULTS: Observations identified 33 steps in the escalation process. The risk-assessment survey (30 surgical staff members, 100% response) and expert consensus group identified 18 hazardous failures associated with these steps. The HFMEA team identified 3 adequately controlled failures; therefore, 15 were subjected to cause analysis. Outdated communication technology, understaffing, and hierarchical barriers were identified as root causes of failure. Participants recommended interventions based on these findings including defined escalation protocols, human factors education, enhanced communication technology, and improved clinical supervision. CONCLUSIONS: Failures in the escalation process amenable to intervention were systematically identified. This mapping of the escalation process will allow tailored interventions to enhance surgical training and patient safety.

The impact of interhospital transfers on surgical quality metrics for academic medical centers.

The emergence of pay-for-performance systems pose a risk to an academic medical center's (AMC) mission to provide care for interhospital surgical transfer patients. This study examines quality metrics and resource consumption for a sample of these patients from the University Health System Consortium (UHC) and our Department of Surgery (DOS). Standard benchmarks, including mortality rate, length of stay (LOS), and cost, were used to evaluate the impact of interhospital surgical transfers versus direct admission (DA) patients from January 2010 to December 2012. For 1,423,893 patients, the case mix index for transfer patients was 38 per cent (UHC) and 21 per cent (DOS) greater than DA patients. Mortality rates were 5.70 per cent (UHC) and 6.93 per cent (DOS) in transferred patients compared with 1.79 per cent (UHC) and 2.93 per cent (DOS) for DA patients. Mean LOS for DA patients was 4 days shorter. Mean total costs for transferred patients were greater $13,613 (UHC) and $13,356 (DOS). Transfer patients have poorer outcomes and consume more resources than DA patients. Early recognition and transfer of complex surgical patients may improve patient rescue and decrease resource consumption. Surgeons at AMCs and in the community should develop collaborative programs that permit collective assessment and decision-making for complicated surgical patients.

The quality of surgical care in safety net hospitals: a systematic review.

OBJECTIVE: The quality of surgical care in safety net hospitals (SNHs) is not well understood owing to sparse data that have not yet been analyzed systematically. We hypothesized that on average, SNHs provide a lesser quality of care for surgery patients than non-SNHs. STUDY DESIGN: We performed a systematic review of published literature on quality of surgical care in SNHs in accordance with guidelines from the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. We searched within the PubMed, CINAHL, and Scopus online databases, and included peer-reviewed, English-language, scientific papers published between 1995 and 2013 that analyzed primary or secondary data on ≥1 of the domains of quality (safety, effectiveness, efficiency, timeliness, patient centeredness, and equity) of surgical care in a US hospital or system that met the Institute of Medicine definition of a SNH. Each article was reviewed independently by ≥2 co-investigators. A data abstraction tool was used to record the eligibility, purpose, design, results, conclusion, and overall quality of each article reviewed. Disagreements over eligibility and data were resolved by group discussion. The main results and conclusions abstracted from the included articles were then analyzed and presented according to the quality domains addressed most clearly by each article. PRINCIPAL FINDINGS: Our initial search identified 1,556 citations, of which 86 were potentially eligible for inclusion. After complete review and abstraction, only 19 of these studies met all inclusion criteria. SNHs performed significantly worse than non-SNHs in measures of timeliness and patient centeredness. Surgical care in SNHs tended to be less equitable than in non-SNHs. Data on the safety of surgical care in SNHs were inconsistent. CONCLUSION: Although data are limited, there seems to be need for improvement in particular aspects of the quality of surgical care provided in SNHs. Thus, SNHs should be priority settings for future quality improvement interventions in surgery. Such initiatives could have disproportionately greater impact in these lower-performing settings and would address directly any health care disparities among the poor, underserved, and most vulnerable populations in the United States.

Variation in surgical quality measure adherence within hospital referral regions: do publicly reported surgical quality measures distinguish among hospitals that patients are likely to compare?

OBJECTIVE: To determine whether surgical quality measures that Medicare publicly reports provide a basis for patients to choose a hospital from within their geographic region. DATA SOURCE: The Department of Health and Human Services' public reporting website, http://www.medicare.gov/hospitalcompare. STUDY DESIGN: We identified hospitals (n = 2,953) reporting adherence rates to the quality measures intended to reduce surgical site infections (Surgical Care Improvement Project, 1-3) in 2012. We defined regions within which patients were likely to compare hospitals using the hospital referral regions (HRRs) from the Dartmouth Atlas of Health Care Project. We described distributions of reported SCIP adherence within each HRR, including medians, interquartile ranges (IQRs), skewness, and outliers. PRINCIPAL FINDINGS: Ninety-seven percent of HRRs had median SCIP-1 scores ≥95 percent. In 93 percent of HRRs, half of the hospitals in the HRR were within 5 percent of the median hospital's score. In 62 percent of HRRs, hospitals were skewed toward the higher rates (negative skewness). Seven percent of HRRs demonstrated positive skewness. Only 1 percent had a positive outlier. SCIP-2 and SCIP-3 demonstrated similar distributions. CONCLUSIONS: Publicly reported quality measures for surgical site infection prevention do not distinguish the majority of hospitals that patients are likely to choose from when selecting a surgical provider. More studies are needed to improve public reporting's ability to positively impact patient decision making.

Impact of improved documentation on an academic neurosurgical practice.

OBJECT: Accuracy in documenting clinical care is becoming increasingly important; it can greatly affect the success of a neurosurgery department. As patient outcomes are being more rigorously monitored, inaccurate documentation of patient variables may present a distorted picture of the severity of illness (SOI) of the patients and adversely affect observed versus expected mortality ratios and hospital reimbursement. Just as accuracy of coding is important for generating professional revenue, accuracy of documentation is important for generating technical revenue. The aim of this study was to evaluate the impact of an educational intervention on the documentation of patient comorbidities as well as its impact on quality metrics and hospital margin per case. METHODS: All patients who were discharged from the Department of Neurosurgery of the Penn State Milton S. Hershey Medical Center between November 2009 and June 2012 were evaluated. An educational intervention to improve documentation was implemented and evaluated, and the next 16 months, starting in March 2011, were used for comparison with the previous 16 months in regard to All Patient Refined Diagnosis-Related Group (APR-DRG) weight, SOI, risk of mortality (ROM), case mix index (CMI), and margin per discharge. RESULTS: The APR-DRG weight was corrected from 2.123 ± 0.140 to 2.514 ± 0.224; the SOI was corrected from 1.8638 ± 0.0855 to 2.154 ± 0.130; the ROM was corrected from 1.5106 ± 0.0884 to 1.801 ± 0.117; and the CMI was corrected from 2.429 ± 0.153 to 2.825 ± 0.232, and as a result the average margin per discharge improved by 42.2%. The mean values are expressed ± SD throughout. CONCLUSIONS: A simple educational intervention can have a significant impact on documentation accuracy, quality metrics, and revenue generation in an academic neurosurgery department.

Rapid core measure improvement through a "business case for quality".

Incentives to improve performance are emerging as revenue or financial penalties are linked to the measured quality of service provided. The HCA "Getting to Green" program was designed to rapidly increase core measure performance scores. Program components included (1) the "business case for quality"-increased awareness of how quality drives financial performance; (2) continuous communication of clinical and financial performance data; and (3) evidence-based clinical protocols, incentives, and tools for process improvement. Improvement was measured by comparing systemwide rates of adherence to national quality measures for heart failure (HF), acute myocardial infarction (AMI), pneumonia (PN), and surgical care (SCIP) to rates from all facilities reporting to the Centers for Medicare and Medicaid Services (CMS). As of the second quarter of 2011, 70% of HCA total measure set composite scores were at or above the 90th percentile of CMS scores. A test of differences in regression coefficients between the CMS national average and the HCA average revealed significant differences for AMI (p = .001), HF (p = .012), PN (p < .001), and SCIP (p = .015). This program demonstrated that presentation of the financial implications of quality, transparency in performance data, and clearly defined goals could cultivate the desire to use improvement tools and resources to raise performance.

A framework for improving access and customer service times in health care: application and analysis at the UCLA Medical Center.

There has been an increasing emphasis on health care efficiency and costs and on improving quality in health care settings such as hospitals or clinics. However, there has not been sufficient work on methods of improving access and customer service times in health care settings. The study develops a framework for improving access and customer service time for health care settings. In the framework, the operational concept of the bottleneck is synthesized with queuing theory to improve access and reduce customer service times without reduction in clinical quality. The framework is applied at the Ronald Reagan UCLA Medical Center to determine the drivers for access and customer service times and then provides guidelines on how to improve these drivers. Validation using simulation techniques shows significant potential for reducing customer service times and increasing access at this institution. Finally, the study provides several practice implications that could be used to improve access and customer service times without reduction in clinical quality across a range of health care settings from large hospitals to small community clinics.

Nicaraguan surgical and anesthesia infrastructure: survey of Ministry of Health hospitals.

BACKGROUND: Developing countries have surgical and anesthesia needs that are unique and disparate compared to those of developed countries. However, the extent of these disparities and the specific country-based needs are, for the most part, unknown. The goal of this study was to assess the surgical capacity of Nicaragua's public hospitals as part of a multinational study. METHODS: A survey adapted from the World Health Organization Tool for Situational Analysis to Assess Emergency and Essential Surgical care was used to study 28 primary, departmental, regional, and national referral hospitals within the Ministry of Health system. Data were obtained at the national and hospital levels via interviews with administrators and surgical and anesthesia chiefs of services. RESULTS: There are 580 obstetrician/gynecologists (OB/GYN), 1,040 non-OB/GYN surgeons, and 250 anesthesiologists in Nicaragua. Primary, departmental, regional, and national referral hospitals perform an annual average of 374, 4,610, 7,270, and 7,776 surgeries, respectively. All but six primary hospitals were able to perform surgeries. Four hospitals reported routine water shortages. Routine medication shortages were reported in 11 hospitals. Eight primary hospitals lacked blood banks on site. Of 28 hospitals, 22 reported visits from short-term surgical brigades within the past 2 years. Measurement of surgical outcomes was inconsistent across hospitals. CONCLUSIONS: Surgical capacity varies by hospital type, with primary hospitals having the least surgical capacity and surgical volume. Departmental, regional, and national referral hospitals have adequate surgical capacity. Surgical subspecialty care appears to be insufficient, as evidenced by the large presence of NGOs and other surgical brigade teams filling this gap.

Appraising hospital performance by using the JCHAO/CMS quality measures in Southern Italy.

OBJECTIVES: The main objective of the present study was to estimate the uptake to quality indicators that reflect the current evidence-based recommendations and guidelines. METHODS: A retrospective review of medical records of patients admitted to two hospitals in the South of Italy was conducted. For the purposes of the analysis, a sets of quality indicators has been used from the Joint Commission on Accreditation of Hospital Organizations and Centers for Medicare & Medicaid Services. Four areas of care were selected: acute myocardial infarction (AMI), heart failure (HF), pneumonia (PN), and surgical care improvement project (SCIP). Frequency or median was calculated, as appropriate, for each indicator. A composite score was calculated to estimate the overall performance for each area of care. RESULTS: A total of 1772 medical records were reviewed. The adherence rates showed a wide-ranging variability among the selected indicators. The use of aspirin and angiotensin-converting enzyme inhibitor (ACEI) or angiotensin receptor blocker (ARB) for AMI, the use of ACEI or ARB for HF, the use of appropriate thromboembolism prophylaxis and appropriate hair removal for surgical patients almost approached optimal adherence. At the other extreme, rates regarding adherence to smoking-cessation counseling in AMI and HF patients, discharge instructions in HF patients, and influenza and pneumococcal vaccination in pneumonia patients were noticeably intangible. Overall, the recommended processes of care among eligible patients were provided in 70% for AMI, in 32.4% for HF, in 46.4% for PN, and in 46% for SCIP. CONCLUSIONS: The results show that there is still substantial work that lies ahead on the way to improve the uptake to evidence-based processes of care. Improvement initiatives should be focused more on domains of healthcare than on specific conditions, especially on the area of preventive care.

Faculty clinical quality goals drive improvement in University HealthSystem Consortium outcome measures.

Mortality, length of stay (LOS), patient safety indicators (PSIs), and hospital-acquired conditions (HACs) are routinely reported by the University HealthSystem Consortium (UHC) to measure quality at academic health centers. We hypothesized that a clinical quality measurable goal assigned to individual faculty members would decrease UHC measures of mortality, LOS, PSIs, and HACs. For academic year (AY) 2010-2011, faculty members received a clinical quality goal related to mortality, LOS, PSIs, and HACs. The quality metric constituted 25 per cent of each faculty member's annual evaluation clinical score, which is tied to compensation. The outcomes were compared before and after goal assignment. Outcome data on 6212 patients from AY 2009-2010 were compared with 6094 patients from AY 2010-2011. The mortality index (0.89 vs 0.93; P = 0.73) was not markedly different. However, the LOS index decreased from 1.01 to 0.97 (P = 0.011), and department-wide PSIs decreased significantly from 285 to 162 (P = 0.011). Likewise, HACs decreased from 54 to 18 (P = 0.0013). Seven (17.9%) of 39 faculty had quality grades that were average or below. Quality goals assigned to individual faculty members are associated with decreased average LOS index, PSIs, and HACs. Focused, relevant quality assignments that are tied to compensation improve patient safety and outcomes.

[Assessment of care quality in department of general surgery : usefulness of administrative database]. / Evaluation de la qualité des soins dans un service de chirurgie générale Utilité d'une base de données administrative .

BACKGROUND: Administrative database, used previously for control of cost, patient flow and invoicing, offer to researchers a large sample of patients representative of population providing interesting informations in the field of descriptive and analytic epidemiology with less cost. AIM: To assess the usefulness of administrative database for quality of care and research. METHODS: It was a prospective study concerning 4690 hospitalisations in Department B of General Surgery of hôpital Charles Nicolle during a period of 18 months, between June 1st, 2008 and December 31st, 2009. A descriptive analysis followed by a pronostic study with a univariate and multivariate analysis was performed. RÉSULTATS : Our study showed the usefulness of an administrative database in assessing the quality of care, it allowed us to determine postoperative mortality rate (2.7%), deep morbidity (2.5%), parietal morbidity (1.2%), medical complications (6%), nosocomial infections (3.6%) and re intervention (2.7%), with independent predictive factors of these events. To reduce the incidence of these events we should reduce length of pre-operative stay, prevent intra operative accidents, avoid intra operative bleeding in order to reduce intra operative transfusions and avoid as far as possible the stay in ICU Independent predictors of post trauma death are multiple trauma [OR: 6.14, 95% (from 1.68 to 16.94), p = 0.002], a traumatized patient in distress on arrival [OR: 8.74, 95% (3.59 -27.77), p = 0.000] and overall medical complications [OR: 13.18, 95% (from 4.01 to 31.25), p=0.000]. The ISS is a good discriminative indice to assess the severity and life-threatening risk. CONCLUSION: Administrative databases provide information on the efficiency of care, it helps to realise observational studies on large samples representative of the population at low cost. They are very useful in the research, despite the lack of clinical data.
