Definition of the indicator

Proportion of index interventions (eligible population) followed by a potentially avoidable reoperation (cases).

 

Cases

Only reoperations occurring during the same hospitalization as the index intervention are included. Reoperations are considered as potentially avoidable if they are related to an anatomic site opened or manipulated during the index intervention, unplanned at the time of the index operation, and if they reflect a surgical failure or a complication due to surgery rather than the worsening of the underlying disease.

The algorithm (see below) classifies a reoperation as potentially avoidable if the same organ group was involved in both the index operation (step 1) and a complication related to surgery (steps 2 and 3) or an unplanned reoperation (step 4).

The following reoperations, although performed on an other organ group, were also classified as potentially avoidable: internal organ resection or limb amputation after a vascular procedure (step 5), reopening of laparotomy or thoracotomy (step 6), control of hemorrhage (step 7), revision of a surgical wound (step 8).

 

Eligible population

All therapeutic surgical interventions are eligible. An intervention was defined as a series of procedures, each performed within an interval of less than two hours from the previous one. A surgical intervention required at least a breaking of skin or mucous membrane; punctures and injections were not considered surgical. A therapeutic intervention included at least one non-diagnostic procedure; a simple biopsy was therefore not included. Endoscopic and endovascular treatments requiring a hospital stay are included.

 

Risk adjustment

The expected values are computed by an adjustment logistic regression model based on following variables: SQLape® categories, age, gender, elective admission and first day operation. SQLape® groups are protected by copyright
(© Yves Eggli, 2009). The standard values were computed on a sample of about 1.437 millions of surgical and therapeutic procedures, performed in 2004 in the United States of America.

 

Scientific validation

The sensitivity and the specificity of the screening algorithm were 75% and 72% (cross validation). The area under the ROC curve of the prediction model was 0.76 in the validation set, indicating fair discrimination (18’187 interventions in a Swiss University hospital (years 1997-1999). This result was confirmed (area under the ROC curve about 0.80) with the present adjustment model (1.437 millions of US interventions, year 2004).

Comments

The rational of the rules used to set the gold standard (table) is given in following paragraphs :

Several practices have been shown to reduce surgical infections; in addition simply informing the surgeons of their infection rates subsequently decreased these rates [1-4], Wide variations in clinical anastomosis leak after gastrointestinal surgery were found between surgeons and are largely considered to reflect surgical skills [5-7]. Hemorrhage occurring immediately after surgery usually indicates inadequate operative hemostasis or a technical mishap such as a slipped ligature or unrecognized trauma to a blood vessel; later hemorrhage is often related to infection or an anastomotic dehiscence that has eroded vessels at operative site [8,9]. Fascial disruptions (evisceration) are often the results of technical shortcomings even though there are patient related risk factors;  common causes are suture break, slipped knot, excessive stitch interval or a suture tearing through the fascia [10,11]. Kennedy, as early as 1934, claimed for him and his master Joseph Price not one wound disruption with evisceration in 56 years of abdominal surgery due to their constant technique of closure [12]. In a recent review on abdominal incision wound breakdown, Cliby wrote “it is entirely within our ability to eliminate most early dehiscence with proper attention to suture technique, stitch placement and proper surgical technique” [10]. Similarly, optimal sternal closure has been shown to preclude sternal dehiscence of sternotomy, the most common incision used by cardiothoracic surgeons [13]. Incisional hernia is one of the most frequent complications of open abdominal surgery requiring reoperation but this late complication was never encountered in our study, which included only reoperation during the same hospitalization. Obviously, organ injury or foreign body accidentally left during the index procedure and early mechanical complications of a material leading to reoperation can be viewed more as a consequence of inadequate technique than as a consequence of a high risk patient. Based on these findings, reoperations for complications 1) to 6) were judged avoidable (Table).

Post operative obstruction requiring laparotomy is mostly due to adhesions which may develop in all patients undergoing abdominal or pelvic surgery (including laparoscopy), even if careful attention is paid to reducing tissue trauma and ensuring haemostasis. No strategy has been shown to decrease incidence of bowel obstruction, which remains fairly constant over time [14-16]. There is currently no prophylaxis of compartment syndrome, a devastating complication requiring an urgent fasciotomy, occurring after trauma, vascular surgery and rarely other surgical procedures [17,18],. Based on these findings, reoperations due to complications 10 and 11 were considered unavoidable.

Surgical failure was considered avoidable only if an incomplete initial procedure was the cause of the revision (cause 12). A calculated conservative approach was considered as not avoidable, because the risk of reoperation was evaluated at the moment of the index intervention (cause 13). Similarly, the possible replacement of a temporary device by a permanent one is always in mind of the operator (cause 15). The relapse or worsening of the underlying disease (cause 14) cannot be attributed to the index intervention. Thus reoperations for causes 13-15 were considered unavoidable.

Reoperations for complications 7-9 and for surgical failure of undetermined origin (16) were considered of undetermined preventability, because both technical skills and patients characteristics might contribute to the outcome. Surgical techniques have been shown to influence the incidence of most post operative fistulas: lymph [19], bronchiopleural [20,21] pharyngocutaneous [22] , genital [23,24], etc.;  but some patients are more likely to develop such complications. Vascular site patency depends on many factors including patient factors, lesion factors and procedural factors [25]. The role of the surgeon on venous graft patency in coronary bypass has been highlighted in numerous studies: atraumatic methods as a“no touch” technique aimed at minimizing vascular damage during vessel harvesting reduce graft failure [26-28]. Risks for developing anastomotic strictures in urologic surgery are related to operative factors (like intra operative bleeding, tension free anastomosis) as well as patient co morbidities (like diabetes or vascular disease) [29-31].

Causes of reoperations

The gold standard against which the screening algorithm has been tested, have been set by the review of routinely collected data and medical records of 809 operation/reoperation pair in a random sample of 7370 interventions in a Swiss university hospital. One hundred and sixty nine reoperations were unrelated to the initial surgical site; 331 reoperations related to the initial surgical site were planned; 309 were unplanned at the time of the index intervention and related to the initial surgical site.

The causes of those unplanned reoperations related to an index surgical site are as follows:

Screening for potentially avoidable reoperations

Figure 1 shows the algorithm that is proposed to screen potentially avoidable reoperations. Each bifurcation in the graph is called a step; steps are numbered 1 through 8. Clinical judgment was used to allocate each ICD9-CM procedure code and ICD 10 diagnosis code of surgery related complications to 30 organ groups (Appendix A, step 1). Some procedures were assigned to two organ groups: for instance a repair of a fistula involving a urinary and a digestive organ, an amputation of a limb segment which was also allocated to the distal adjoining limb part. Reoperations were classified as potentially avoidable if the same organ group was involved in both the index operation and a complication related to surgery (steps 2 and 3) or an unplanned reoperation (step 4). Some reoperations on an other organ group were also classified as potentially avoidable if organ resection after a vascular procedure (step 5), reopening of laparotomy or thoracotomy (step 6), control of hemorrhage (step 7), revision of a surgical wound (step 8). The sensitivity and the specificity of the method applied on the 406 operation/reoperation pairs of the test sample reach respectively 75% and 72%.
