Toward optimal recording of surgical complications: Concurrent tracking compared to the discharge data set

Cirse Quality Assurance Document and Standards for Classification of Complications: The Cirse Classification System

Interventional radiology provides a wide variety of vascular, nonvascular, musculoskeletal, and oncologic minimally invasive techniques aimed at therapy or palliation of a broad spectrum of pathologic conditions. Outcome data for these techniques are globally evaluated by hospitals, insurance companies, and government agencies targeting in a high-quality health care policy, including reimbursement strategies. To analyze effectively the outcome of a technique, accurate reporting of complications is necessary. Throughout the literature, numerous classification systems for complications grading and classification have been reported. Until now, there has been no method for uniform reporting of complications both in terms of definition and grading. The purpose of this CIRSE guideline is to provide a classification system of complications based on combining outcome and severity of sequelae. The ultimate challenge will be the adoption of this system by practitioners in different countries and health economies within the European Union and beyond.

[Quality of documentation of intraoperative and postoperative complications : improvement of documentation for a nationwide quality assurance program and comparison with routine data]

INTRODUCTION

Complications after cholecystectomy are continuously documented in a nationwide database in Germany. Recent studies demonstrated a lack of reliability of these data. The aim of the study was to evaluate the impact of a control algorithm on documentation quality and the use of routine diagnosis coding as an additional validation instrument.

METHODS

Completeness and correctness of the documentation of complications after cholecystectomy was compared over a time interval of 12 months before and after implementation of an algorithm for faster and more accurate documentation. Furthermore, the coding of all diagnoses was screened to identify intraoperative and postoperative complications.

RESULTS AND DISCUSSION

The sensitivity of the documentation for complications improved from 46 % to 70 % (p = 0.05, specificity 98 % in both time intervals). A prolonged time interval of more than 6 weeks between patient discharge and documentation was associated with inferior data quality (incorrect documentation in 1.5 % versus 15 %, p < 0.05). The rate of case documentation within the 6 weeks after hospital discharge was clearly improved after implementation of the control algorithm. Sensitivity and specificity of screening for complications by evaluating routine diagnoses coding were 70 % and 85 %, respectively. The quality of documentation was improved by implementation of a simple memory algorithm.

Positioning-related complications of minimally invasive radical prostatectomies

BACKGROUND AND PURPOSE

Because of recent advances in minimally invasive surgical techniques, robot-assisted radical prostatectomy (RARP) has become the primary treatment option in prostate cancer. RARP, however, necessitates patients to be placed in a steep Trendelenberg position, which presents multiple opportunities for complications relating to the positioning of the patient. Our study aims to study the prevalence and demographic predictors of these positioning complications and assess their impacts on length of stay (LOS) and total cost.

PATIENTS AND METHODS

We included patients who underwent RP from 2008 to 2009 using data extracted from the Nationwide Inpatient Sample database. Positioning complications (eye, nerve, compartment syndrome/rhabdomyolysis) were identified using patient-level diagnosis and procedural International Classification of Disease, 9th edition, Clinical Modification codes. Logistic regression models assessed relationships between demographic factors and occurrence of complications and the effects of them on prolonged LOS and total inpatient cost.

RESULTS

Positioning complications occurred in 0.4% of cases with eye complications contributing the most to this frequency. Laparoscopic RP procedure (odds ratio [OR]=2.88, P<0.01) and comorbidities (OR=2.34, P<0.01) were highly associated with increased odds of positioning complication occurrence, whereas RARP procedures (OR=0.93, P>0.4) were not associated with positioning complications. Having positioning complications increased a patient's odds of having increased inpatient costs and extended LOS by almost 400% and 300%, respectively.

CONCLUSION

The steep Trendelenberg position used in RARP was not shown to be associated with patient positioning-related complications in this sample. The occurrence of positioning-related complications, however, places huge burdens on total inpatient costs and LOS.

[Reporting and grading of complications after urologic surgical procedures: an ad hoc EAU guidelines panel assessment and recommendations]

CONTEXT

The incidence of postoperative complications is still the most frequently used surrogate marker of quality in surgery, but no standard guidelines or criteria exist for reporting surgical complications in the area of urology.

OBJECTIVE

To review the available reporting systems used for urologic surgical complications, to establish a possible change in attitude towards reporting of complications using standardised systems, to assess systematically the Clavien-Dindo system when used for the reporting of complications related to urologic surgical procedures, to identify shortcomings in reporting complications, and to propose recommendations for the development and implementation of future reporting systems that are focused on patient-centred outcomes.

EVIDENCE ACQUISITION

Standardised systems for reporting and classification of surgical complications were identified through a systematic review of the literature. To establish a possible change in attitude towards reporting of complications related to urologic procedures, we performed a systematic literature search of all papers reporting complications after urologic surgery published in European Urology, Journal of Urology, Urology, BJU International, and World Journal of Urology in 1999-2000 and 2009-2010. Data identification for the systematic assessment of the Clavien-Dindo system currently used for the reporting of complications related to urologic surgical interventions involved a Medline/Embase search and the search engines of individual urologic journals and publishers using Clavien, urology, and complications as keywords. All selected papers were full-text retrieved and assessed; analysis was done based on structured forms.

EVIDENCE SYNTHESIS

The systematic review of the literature for standardised systems used for reporting and classification of surgical complications revealed five such systems. As far as the attitude of urologists towards reporting of complications, a shift could be seen in the number of studies using most of the Martin criteria, as well as in the number of studies using either standardised criteria or the Clavien-Dindo system. The latter system was not properly used in 72 papers (35.3%).

CONCLUSIONS

Uniformed reporting of complications after urologic procedures will aid all those involved in patient care and scientific publishing (authors, reviewers, and editors). It will also contribute to the improvement of the scientific quality of papers published in the field of urologic surgery. When reporting the outcomes of urologic procedures, the committee proposes a series of quality criteria.

Tracking intraoperative complications

BACKGROUND

Relatively little is known or understood about the nature of complications that occur during a surgical procedure. Definitions, classification, and documentation are substantive challenges to comprehensive event capture. We hypothesized that our prospective complication database (ie, Surgical Activity Tracking System) would supplement traditional sources of intraoperative complication reporting.

STUDY DESIGN

Consecutive patients undergoing surgery on a single general surgical service from June 2005 through May 2010 were selected for analysis. All cases had been entered into the Surgical Activity Tracking System, a prospective complication database that identifies and captures complications in real time, using a specially trained nurse practitioner. Intraoperative complications were grouped into 1 of 9 categories. Operative reports and discharge summaries were analyzed by an independent reviewer to determine if the complication(s) had been documented by a traditional data source.

RESULTS

Eight thousand eight hundred and ninety-six operations were performed on 7,729 patients during the study period. One hundred and thirty-seven patients (1.5%) experienced an intraoperative complication. Nonintestinal organ lacerations, inadvertent enterotomies, and hemorrhage were the most common adverse events. The operative reports failed to mention 20 of the 151 complications (13%), and discharge summaries failed to report 22 complications (14%). Some complications, such as inadvertent enterotomy, were almost always reported, but others such as arrhythmia, were only occasionally described (25%).

CONCLUSIONS

Our prospective complication tracking system identified a considerable number of complications that were not available in either the operative report or discharge summary. The number of unreported adverse events varied greatly by category, suggesting opportunities for improvement in both complication identification and tracking.

Is risk-adjusted mortality an indicator of quality of care in general surgery?: a comparison of risk adjustment to peer review

OBJECTIVE(S)

Profiling of hospitals using risk-adjusted mortality rates as a measure of quality is becoming increasingly frequent. We sought to determine the validity of this approach by comparing the risk-adjusted predicted mortality to the findings of concurrent peer review and retrospective chart review of deaths that occur on a general surgery service.

METHODS

Consecutive patients admitted to a busy general surgery service from January 2000 to January 2006 were prospectively entered into the Surgical Activity Tracking System. Rigorous, systematic peer review was performed concurrently by service members on all deaths. Adjudication was later validated by an independent senior surgeon. Three methodologies of risk adjustment (University Health Consortium, Physiological and Operative Severity Score for the enUmeration of Mortality, and the Charlson index) were used and compared the "excess mortality" predicted by each to the number of potentially preventable deaths determined by peer review.

RESULTS

A total of 9623 patients were admitted and 75 died (0.7%). University Health Consortium and Physiological and Operative Severity Score predicted an excess mortality of 62 and 65 deaths, respectively; Charlson predicted that 73% of the cohort would be dead in 1 year. Concurrent and retrospective peer review found that death was potentially preventable in only 22 and 21 patients, respectively.

CONCLUSIONS

Peer adjudication and extensive clinical review adds much to the analysis of an adverse outcome, similar to the "black box" in an airplane crash. Although methods of risk adjustment may be helpful in identifying patients for peer review, they should be used for internal process improvement and not published as metrics of hospital or provider performance.

The accuracy of complications documented in a prospective complication registry

BACKGROUND

The objectives of this study were to evaluate the accuracy of a prospective complication registry for documenting complications and identify possible factors for non-registering.

METHODS

Five hundred randomly selected patients admitted at the Department of Surgery of St. Elisabeth Hospital Tilburg, The Netherlands, in the year 2005, were evaluated for incidence and type of complications by an examination of their medical records and compared with a prospective complication registry. The system was independently reviewed by two persons for missing complications. Patient files with missing complications in the registry were screened for factors possibly responsible for non-registering.

RESULTS

Two hundred thirteen complications were detected, 58 (27%) missing in the registry. There were 50 different types of complications documented. The number of events missing per category were: drug-related (50%, n = 4), organ dysfunction (44%, n = 14), infection-related (25%, n = 19), surgery/intervention-related (23%, n = 14), and hospital-provider errors (19%, n = 7). Not all clinically important complications were adequately documented (e.g., anastomotic leakage). The kappa score was 0.695, making the interrater reliability substantial.

CONCLUSION

The accuracy of registering complications is fairly acceptable compared to the ranges mentioned in literature. It is disappointing that clinically important events are missing in the registry. The inaccuracy could be explained by a great diversity of documented events, due to a broad definition, suggesting ignorance of the responsible team of which events to register.

Death after bowel resection: patient disease, not surgeon error

INTRODUCTION

Although bowel resection is associated with a significant mortality rate, little is known about the demographics of the patients and how often surgical error is the primary cause of death. We sought to use a rigorous prospective quality database incorporating standardized peer review, to define how often patients die from provider-related causes.

MATERIALS AND METHODS

All patients undergoing bowel resection with anastomosis at a university hospital from July 2003 to June 2006 were entered into a prospectively maintained quality database. Patients were seen daily with house staff by a specially trained nurse practitioner who recorded demographics and complications. Clinical case reviews were conducted monthly. Five hundred sixty-six patients underwent bowel resection with anastomosis during the study period.

DISCUSSION

One hundred ninety-three patients suffered at least one complication (34.1%) and there were 20 deaths (3.5%). In 17 cases, death was deemed unavoidable due to patient disease; most occurred in patients who developed ischemic bowel while hospitalized for a serious concomitant illness. In only one case did death appear clearly related to a surgical complication (0.17%). Death after bowel resection typically reflects the need for urgent surgery in extreme circumstances and not surgeon error. Postoperative mortality rate in this population appears to be poor indicator of surgical quality.

A 10-year analysis of venous thromboembolism on the surgical service: the effect of practice guidelines for prophylaxis

BACKGROUND

There is a national effort to decrease the incidence of venous thromboembolism (VTE) in surgical patients by encouraging compliance with established guidelines for prophylaxis. Reported compliance with these guidelines has been poor. The outcome of noncompliance in terms of morbidity and mortality in surgical patients is unknown. We sought to determine if there has been a decrease in the incidence of symptomatic VTE since implementation of the guidelines and whether there has been compliance with the guidelines in individual patients; we also analyzed the outcome of a cohort with VTE.

METHODS

We reviewed the records of all patients with symptomatic VTE on 3 surgery services over the 10-year period since initial publication of the guidelines. We determined in each patient whether there was compliance with the guidelines. We weighted the morbidity of each episode of VTE based on the likelihood of short-term mortality and long-term morbidity to determine the disease burden.

RESULTS

Of 37,615 patients, 172 developed a VTE (0.46%), and the incidence increased gradually over the years of the study. There was partial or complete compliance with the guidelines in 84% of the patients, but 37% of the VTEs were considered to be preventable. The disease burden was greatest in the higher-risk patients-there were 20 deaths (6%), 4 of which were caused by a pulmonary embolus.

CONCLUSIONS

Despite one of the highest published rates of compliance with the guidelines for prophylaxis, the rate of symptomatic VTE is increasing.
