- Abstract
Objective: To derive and validate a polygenic risk score (PRS) to predict the occurrence and severity of diverticulitis and to understand the potential for incorporation of a PRS in current decision-making. Background: PRS quantifies genetic variation into a continuous measure of risk. There is a need for improved risk stratification to guide surgical decision-making that could be fulfilled by PRS. It is unknown how surgeons might integrate PRS in decision-making. Methods: We derived a PRS with 44 single-nucleotide polymorphisms associated with diverticular disease in the UK Biobank and validated this score in the Michigan Genomics Initiative (MGI). We performed a discrete choice experiment of practicing colorectal surgeons. Surgeons rated the influence of clinical factors and a hypothetical polygenic risk prediction tool. Results: Among 2812 MGI participants with diverticular disease, 1964 were asymptomatic, 574 had mild disease, and 274 had severe disease. PRS was associated with occurrence and severity. Patients in the highest PRS decile were more likely to have diverticulitis [odds ratio (OR)=1.84; 95% confidence interval (CI), 1.42–2.38)] and more likely to have severe diverticulitis (OR=1.61; 95% CI, 1.04–2.51) than the bottom 50%. Among 213 surveyed surgeons, extreme disease-specific factors had the largest utility (3 episodes in the last year, +74.4; percutaneous drain, + 69.4). Factors with strongest influence against surgery included 1 lifetime episode (−63.3), outpatient management (−54.9), and patient preference (−39.6). PRS was predicted to have high utility (+71). Conclusions: A PRS derived from a large national biobank was externally validated, and found to be associated with the incidence and severity of diverticulitis. Surgeons have clear guidance at clinical extremes, but demonstrate equipoise in intermediate scenarios. Surgeons are receptive to PRS, which may be most useful in marginal clinical situations. Given the current lack of accurate prognostication in recurrent diverticulitis, PRS may provide a novel approach for improving patient counseling and decision-making. [ABSTRACT FROM AUTHOR]

- Abstract
Supplemental Digital Content is available in the text Objective: We sought to measure the extent of variation in episode spending around total hip replacement within and across hospital systems. Summary of Background Data: Bundled payment programs are pressuring hospitals to reduce spending on surgery. Meanwhile, many hospitals are joining larger health systems with the stated goal of improved care at lower cost. Methods: Cross-sectional study of fee-for-service Medicare patients undergoing total hip replacement in 2016 at hospital systems identified in the American Hospital Association Annual Survey. We calculated risk- and reliability-adjusted average 30-day episode payments at the hospital and system level. Results: Average episode payments varied nearly as much within hospital systems ($2515 between the lowest- and highest-cost hospitals, 95% confidence interval $2272–$2,758) as they did between the lowest- and highest-cost quintiles of systems ($2712, 95% confidence interval $2545–$2879). Variation was driven by post-acute care utilization. Many systems have concentrated hip replacement volume at relatively high-cost hospitals. Conclusions: Given the wide variation in surgical spending within health systems, we propose tailored strategies for systems to maximize savings in bundled payment programs. [ABSTRACT FROM AUTHOR]

- Abstract
Objective: To evaluate real-world effects of enhanced recovery protocol (ERP) dissemination on clinical and economic outcomes after colectomy. Summary background data: Hospitals aiming to accelerate discharge and reduce spending after surgery are increasingly adopting perioperative ERPs. Despite their efficacy in specialty institutions, most studies have lacked adequate control groups and diverse hospital settings and have considered only in-hospital costs. There remain concerns that accelerated discharge might incur unintended consequences. Methods: Retrospective, population-based cohort including patients in 72 hospitals in the Michigan Surgical Quality Collaborative clinical registry (N = 13,611) and/or Michigan Value Collaborative claims registry (N = 14,800) who underwent elective colectomy, 2012 to 2018. Marginal effects of ERP on clinical outcomes and risk-adjusted, price-standardized 90-day episode payments were evaluated using mixed-effects models to account for secular trends and hospital performance unrelated to ERP. Results: In 24 ERP hospitals, patients Post-ERP had significantly shorter length of stay than those Pre-ERP (5.1 vs 6.5 days, P < 0.001), lower incidence of complications (14.6% vs 16.9%, P < 0.001) and readmissions (10.4% vs 11.3%, P = 0.02), and lower episode payments ($28,550 vs $31,192, P < 0.001) and postacute care ($3,384 vs $3,909, P < 0.001). In mixed-effects adjusted analyses, these effects were significantly attenuated-ERP was associated with a marginal length of stay reduction of 0.4 days (95% confidence interval 0.2-0.6 days, P = 0.001), and no significant difference in complications, readmissions, or overall spending. Conclusions: ERPs are associated with small reduction in postoperative length of hospitalization after colectomy, without unwanted increases in readmission or postacute care spending. The real-world effects across a variety of hospitals may be smaller than observed in early-adopting specialty centers. [ABSTRACT FROM AUTHOR]

Sheetz, Kyle H., Ibrahim, Andrew M., Regenbogen, Scott E., and Dimick, Justin B.
- Abstract
Objective: To quantify the extent to which payments for laparoscopic and open colectomy are influenced by a surgeon's experience with laparoscopy. Background: Numerous studies suggest that healthcare costs for laparoscopic colectomy are lower than open surgery. None have assessed the importance of surgeon experience on the relative financial benefits of laparoscopy. Methods: We conducted a study of 182,852 national Medicare beneficiaries undergoing laparoscopic or open colectomy between 2010 and 2012. Using instrumental variable methods to account for selection bias, we compared Medicare payments for laparoscopic and open colectomy. We stratified our analysis by surgeons' annual experience with laparoscopic colectomy to determine the influence of provider experience on payments. Results: In the fully adjusted analysis, average episode payments per patient were $2640 [95% confidence interval (CI) −$4091 to −$1189] lower with the laparoscopic approach versus open. Surgeons in the highest quartile of laparoscopic experience demonstrated an average payment savings of $5456 per patient (CI −$7918 to −$2994) in their laparoscopic versus open cases. Among surgeons in the lowest quartile of laparoscopic experience, there was, however, no difference between laparoscopic and open cases (difference: $954, 95% CI −$731 to $2639). Differences in payments were explained by differences in complications rates. Both groups had similar rates of complications for open procedures (least experience, 21%, most experience, 21%; P = 0.45), but differed significantly on rates of complications for laparoscopic cases (least experience, 28%, most experience, 15%; P < 0.01). Conclusions: This population-based study demonstrates that differences in payments between laparoscopic and open colectomy are influenced by surgeon experience. The laparoscopic approach does not reduce payments for patients whose surgeons have limited experience with the procedure. [ABSTRACT FROM AUTHOR]

- Abstract
Objective: The aim of this study was to compare the surgical outcomes of emergency operations performed at critical access and non-critical access hospitals. Background: Critical access hospitals are often the only source of surgical care for rural populations. Previous studies have demonstrated that patients undergoing common, elective operations at these rural hospitals have similar outcomes to their urban counterparts. Little is known, however, about the quality of care these hospitals provide for emergency operations for which they are most essential. Methods: We performed a cross-sectional retrospective review of 219,170 urgent or emergency colon resections among Medicare beneficiaries between 2009 and 2012.We comparedmortality, serious complications, reoperation, and readmission rates at critical access and non-critical access hospitals using a multivariable logistic regression to adjust for patient factors (age, sex, race, Elixhauser comorbidities,) indication (cancer, diverticulitis, obstruction, inflammatory bowel disease, bleeding), year of operation, and type of operation. Results: Operative indications were similar at both critical access and noncritical access hospitals with the most common being cancer (38.5% vs 31.1%) followed by diverticulitis (26.9% vs 28.0%). Compared with patients treated at non-critical access hospitals, patients undergoing surgery at critical access hospitals were less likely to have multiple comorbid diseases (% of patients with 2 or more comorbid conditions, 67.5% vs 75.9%; P < 0.01). After accounting for these differences, patients in critical access hospitals had lower risk-adjusted 30-day mortality rates (14.3% vs 16.2%; P = 0.012) and lower rates of serious complications (11.1% vs 27.2%; P < 0.001). However, critical access hospitals had higher rates of reoperation (2.1% vs 1.4%; P = 0.009) and readmissions (22.3% vs 19.4%; P < 0.001). Conclusions: For emergency colectomy procedures,Medicare beneficiaries in critical access hospitals experienced lower mortality rates but more frequent reoperation and readmission. These findings suggest that critical access hospitals provide safe, essential emergency surgical care, but may need more resources for postoperative care coordination in these high-risk operations.

Regenbogen, Scott E., Shah, Nirav J., Collins, Stacey D., Hendren, Samantha, Englesbe, Michael J., and Campbell Jr., Darrell A.
- Abstract
Objective: To assess the variation in hospitals' approaches to intraoperative fluid management and their association with postoperative recovery. Background: Despite increasing interest in goal-directed, restricted-volume fluid administration for major surgery, there remains little consensus on optimal strategies, due to the lack of institution-level studies of resuscitation practices. Methods: Among 64 hospitals in a state-wide surgical collaborative, we profiled fluid administration practices during 8404 intestinal resections, 22,854 hysterectomies, and 1471 abdominopelvic endovascular procedures. We computed intraoperative fluid balance, accounting for patient morphometry, crystalloid, colloid, blood products, urine, blood loss, duration, and approach. We stratified hospitals by average fluid balance quartile, and compared patterns across disciplines and associations with risk-adjusted postoperative length of stay (pLOS). Results: There was wide variation in fluid balance between hospitals (P < 0.001, all procedures), but significant within-hospital correlation across operations (Pearson rho: intestinal-hysterectomy = 0.50, intestinal-endovascular = 0.36, hysterectomy-endovascular = 0.54, all P < 0.05). Highest fluid balance hospitals had significantly longer adjusted pLOS than lowest balance hospitals for intestinal resection (6.5 vs 5.7 d, P < 0.001) and hysterectomy (1.9 vs 1.7 d, P < 0.001), but not endovascular (2.1 vs 2.3 d, P = 0.69). Risk-adjusted complication rates were not associated with fluid balance rankings. Conclusions: Hospitals' approaches to intraoperative fluid administration vary widely, and their practice patterns are pervasive across disparate procedures. High fluid balance hospitals have 12% to 14% longer risk-adjusted pLOS for visceral abdominal surgery, independent of patient complexity and complications. These findings are consistent with evidence that isovolemic resuscitation in enhanced recovery protocols accelerates recovery of bowel function. [ABSTRACT FROM AUTHOR]

- Abstract
Objective: The aim of the study was to characterize patient-reported outcomes of analgesia practices in a population-based surgical collaborative. Background: Pain control among hospitalized patients is a national priority and effective multimodal pain management is an essential component of postoperative recovery, but there is little understanding of the degree of variation in analgesia practice and patient-reported pain between hospitals. Methods: We evaluated patient-reported pain scores after colorectal operations in 52 hospitals in a state-wide collaborative. We stratified hospitals by quartiles of average pain scores, identified hospital characteristics, pain management practices, and clinical outcomes associated with highest and lowest case-mix-adjusted pain scores, and compared against Hospital Consumer Assessment of Healthcare Providers and Systems pain management metrics. Results: Hospitals with the lowest pain scores were larger (503 vs 452 beds; P < 0.001), higher volume (196 vs 112; P = 0.005), and performed more laparoscopy (37.7% vs 27.2%; P < 0.001) than those with highest scores. Their patients were more likely to receive local anesthesia (31.1% vs 12.9%; P < 0.001), nonsteroidal anti-inflammatory drugs (33.5% vs 14.4%; P < 0.001), and patient-controlled analgesia (56.5% vs 22.8%; P < 0.001). Adverse postoperative outcomes were less common in hospitals with lowest pain scores, including complications (20.3% vs 26.4%; P < 0.001), emergency department visits (8.2% vs 15.8%; P < 0.001), and readmissions (11.3% vs 16.2%; P = 0.01). Conclusions: Pain management after colorectal surgery varies widely and predicts significant differences in patient-reported pain and clinical outcomes. Enhanced postoperative pain management requires dissemination of multimodal analgesia practices. Attention to patient-reported outcomes often omitted from surgical outcomes registries is essential to improving quality from the patient's perspective. [ABSTRACT FROM AUTHOR]

Abdelsattar, Zaid M., Gonzalez, Andrew A., Hendren, Samantha, Regenbogen, Scott E., and Wong, Sandra L.
- Abstract
Objective: The aim of the study was to identify hospital characteristics associated with variation in patient disposition after emergent surgery. Summary background data: Colon resections in elderly patients are often done in emergent settings. Although these operations are known to be riskier, there are limited data regarding postoperative discharge destination. Methods: We evaluated Medicare beneficiaries who underwent emergent colectomy between 2008 and 2010. Using hierarchical logistic regression, we estimated patient and hospital-level risk-adjusted rates of nonhome discharges. Hospitals were stratified into quintiles based on their nonhome discharge rates. Generalized linear models were used to identify hospital structural characteristics associated with nonhome discharges (comparing discharge to skilled nursing facilities vs home with/without home health services). Results: Of the 122,604 patients surviving to discharge after emergent colectomy at 3012 hospitals, 46.7% were discharged to a nonhome destination. There was a wide variation in risk and reliability-adjusted nonhome discharge rates across hospitals (15% to 80%). Patients at hospitals in the highest quintile of nonhome discharge rates were more likely to have longer hospitalizations (15.1 vs 13.2; P < 0.001) and more complications (43.2% vs 34%; P < 0.001). On multivariable analysis, only hospital ownership of a skilled nursing facility (P < 0.001), teaching status (P = 0.025), and low nurse-to-patient ratios (P = 0.002) were associated with nonhome discharges. Conclusions: Nearly half of Medicare beneficiaries are discharged to a nonhome destination after emergent colectomy. Hospital ownership of a skilled nursing facility and low nurse-to-patient ratios are highly associated with nonhome discharges. This may signify the underlying financial incentives to preferentially utilize postacute care facilities under the traditional fee-for-service payment model. [ABSTRACT FROM AUTHOR]

Background: A 10-point Surgical Apgar Score, based on patients' estimated blood loss, lowest heart rate, and lowest mean arterial pressure during surgery, was developed to rate patients' outcomes in general and vascular surgery but has not been tested for patients having orthopaedic surgery. Questions/purposes: For patients undergoing hip and knee arthroplasties, we asked (1) whether the score provides accurate risk stratification for major postoperative complications, and (2) whether it captures intraoperative variables contributing to postoperative risk based on the three parameters independent of preoperative risk. Patients and Methods: We retrospectively reviewed the electronic records for all 3511 patients who underwent a hip or knee arthroplasty from March 2003 to August 2006 and extracted data to calculate a Surgical Apgar Score. We evaluated the relationship between scores and likelihood of major postoperative in-hospital complications and assessed its discrimination and calibration. Results: Complication rates increased monotonically as the score decreased. Even after controlling for preoperative risk, each 1-point decrease in the score was associated with a 34.0% increase (95% confidence interval, 0.66-0.84) in the odds of a complication. The overall discriminatory performance of the score was a c-statistic of 0.61. Seventy-six percent of all major complications occurred in patients classified as low risk with scores of 7 or greater. Conclusions: For patients undergoing hip and knee arthroplasties, the score captures important intraoperative information regarding risk of complications and contributes additional information to preoperative risk, but on its own is insufficient to provide comprehensive postoperative risk stratification for arthroplasties. Level of Evidence: Level II, prognostic study. See Guidelines for Authors for a complete description of levels of evidence. [ABSTRACT FROM AUTHOR]

- Abstract
Communication breakdowns between surgical residents and attending physicians in the pre- and postoperative setting are common contributors to patient injury. These communication transactions might offer an opportunity for safety improvement, but it remains unknown how often resident-attending communication fails, what the current level of attending involvement is, and how often attending input changes the plan for patient care. We conducted a prospective study at 4 Harvard teaching hospitals to address these issues.Three prospective data collection strategies were employed: (1) we randomly selected surgical services and queried residents for the occurrence of predefined critical patient events and the characteristics of attending communications that ensued, (2) on weekends, randomly selected patients were interviewed and their charts reviewed to identify the frequency of attending visitation and how such visits affected processes of care, and (3) on weekends, senior residents on randomly selected surgical services were queried regarding the occurrence of attending-resident discussion of patients in their care.Of 80 critical patient events identified, 26 (33%) were not communicated to attending surgeons. Residents reported that, when contacted, all attending physicians were receptive to communication, whether they were the primary surgeon or providing cross-coverage. Although residents felt that attending contact was unnecessary for safe patient care in 61 (76%) of these events, discussions with attending physicians changed management in 33% (18/54) of cases in which they occurred. Attending surgeons were found to visit their patients on randomly selected weekend days 42% (n = 37) of the time, while 21% (n = 19) had not visited for 2 or greater days. When attending physicians visited patients, however, resident management was modified 46% (n = 36) of the time. Though residents frequently discussed patient management with attending physicians on randomly selected weekends, they failed to do so 16% (n = 58) of the time, which appeared to be related to service-specific variation (χ
2 = 269, P < 0.0001).In the context of both critical patient events and routine patient care, residents often fail to obtain attending surgeons’ input for management decisions. These failures seem to derive more from residents’ perception of necessity than from attending physicians’ receptiveness or interest in being contacted. Once involved, attending physicians frequently modify resident's management decisions. It seems, therefore, that there is significant potential for communication failure and information loss among our 4 institutions. [ABSTRACT FROM AUTHOR]- Published

- Abstract
To evaluate whether adherence to evidence-based best practices in colorectal surgery predicts improved postoperative outcomes.Over a quarter of a million colon and rectal resections are performed annually in the United States. The average postoperative complication rate for these procedures approaches 30%.A panel of colorectal and general surgeons from 3 hospitals (1 academic medical center and 2 community hospitals) was assembled to ascertain a set of 37 evidence-based practices that they felt were the most pertinent to the evaluation and management of a patient undergoing a colorectal resection. Fifteen of these practices were classified as “key processes” for the prevention of complications. We then retrospectively reviewed medical records for 370 consecutive patients undergoing colorectal resection at these institutions. We evaluated the association of best-practice adherence to complications in the subset of patients with outcome data available through the American College of Surgeons National Surgical Quality Improvement Program.Nonadherence rates exceeded 40% for 11 practices (including 2 key processes: avoidance of unnecessary blood transfusions and timely removal of central venous catheters). Among 198 patients with American College of Surgeons National Surgical Quality Improvement Program outcomes data, 38 (19%) experienced complications, of which 31 (82%) involved postoperative infection. Nonadherence to key-processes significantly predicted the occurrence of a complication (P = 0.002). Each additional process missed increased the odds of a postoperative complication by 60% (odds ratio: 1.6; 95% confidence interval: 1.2-2.2).Failures of adherence with best practices in colorectal surgery is associated with an increased occurrence of complications. This study merits further research to confirm that improvement in compliance with perioperative best practices will reduce complication rates significantly. [ABSTRACT FROM AUTHOR]

32. Do Differences in Hospital and Surgeon Quality Explain Racial Disparities in Lower-Extremity Vascular Amputations?

Regenbogen, Scott E., Gawande, Atul A., Lipsitz, Stuart R., Greenberg, Caprice C., and Jha, Ashish K.
- Abstract
To understand whether racial disparities in surgery for lower-extremity arterial disease are minimized by high-quality providers, or instead, differential treatment of otherwise similar patients pervades all settings.Black patients are substantially more likely than whites to undergo amputation rather than revascularization for lower-extremity arterial disease. Because their care is disproportionately concentrated among a small share of providers, some have attributed such disparities to the quality and capacity of these sites.We evaluated all 86,865 white or black fee-for-service Medicare beneficiaries 65 and older who underwent major lower-extremity vascular procedures. Using generalized linear mixed models with random effects, we computed risk-adjusted odds of amputation by race overall, and after serial substratification by salient patient and provider characteristics.Blacks were far more likely to undergo amputation (45% vs. 20%). Their procedures were performed more often by nonspecialists (41% vs. 27%; P < 0.001), in low-volume hospitals (40% vs. 32%; P < 0.001), with high amputation rates (53% vs. 29%; P < 0.001). Controlling for differences in comorbidity, disease severity, and surgeon and hospital performance, blacks’ odds of amputation remained 1.7 times greater (95% confidence interval: 1.6-1.9). Even among highest-performing providers—vascular specialists in high-volume, urban teaching hospitals with angioplasty facilities—racial gaps persisted (risk-adjusted amputation rates: 7% for blacks vs. 4% for whites, P < 0.001; odds ratio: 1.8, 95% confidence interval: 1.5-2.1).Black patients with critical limb ischemia face significantly higher risk of major amputation, even when treated by providers with highest likelihoods of revascularization. Increased referral to high-performing providers might increase limb-preservation, but cannot eliminate disparities until equitable treatment can be ensured in all settings. [ABSTRACT FROM AUTHOR]

Background Over 180 000 coronary artery bypass grafting (CABG) procedures are performed annually, accounting for $7 to $10 billion in episode expenditures. Assessing tradeoffs between spending and quality contributing to value during 90-day episodes has not been conducted but is essential for success in bundled reimbursement models. We, therefore, identified determinants of variability in hospital 90-day episode value for CABG. Methods Medicare and private payor admissions for isolated CABG from 2014 to 2016 were retrospectively linked to clinical registry data for 33 nonfederal hospitals in Michigan. Hospital composite risk-adjusted complication rates (≥1 National Quality Forum-endorsed, Society of Thoracic Surgeons measure: deep sternal wound infection, renal failure, prolonged ventilation >24 hours, stroke, re-exploration, and operative mortality) and 90-day risk-adjusted, price-standardized episode payments were used to categorize hospitals by value by defining the intersection between complications and spending. Results Among 2573 total patients, those at low- versus high-value hospitals had a higher percentage of prolonged length of stay >14 days (9.3% versus 2.4%, P=0.006), prolonged ventilation (17.6% versus 4.8%, P<0.001), and operative mortality (4.8% versus 0.6%, P=0.001). Mean total episode payments were $51 509 at low-compared with $45 526 at high-value hospitals (P<0.001), driven by higher readmission ($3675 versus $2177, P=0.005), professional ($7462 versus $6090, P<0.001), postacute care ($7315 versus $5947, P=0.031), and index hospitalization payments ($33 474 versus $30 800, P<0.001). Among patients not experiencing a complication or 30-day readmission (1923/2573, 74.7%), low-value hospitals had higher inpatient evaluation and management payments ($1405 versus $752, P<0.001) and higher utilization of inpatient rehabilitation (7% versus 2%, P<0.001), but lower utilization of home health (66% versus 73%, P=0.016) and emergency department services (13% versus 17%, P=0.034). Conclusions To succeed in emerging bundled reimbursement programs for CABG, hospitals and physicians should identify strategies to minimize complications while optimizing inpatient evaluation and management spending and use of inpatient rehabilitation, home health, and emergency department services.

- Abstract
Objective: To develop and evaluate an intervention to reduce breakdowns in communication during inpatient surgical care., Background: Communication breakdowns are the second most common cause of avoidable surgical adverse events after technical errors., Methods: In a pre- and postintervention study, a random selection of patients on the surgical services of 4 teaching hospitals were observed according to 3 measures: (1) resident-attending communication of critical patient events (eg, transfer into the intensive care unit, unplanned intubation, cardiac arrest); (2) resident-attending notification regarding routine weekend patient status; and (3) frequency of weekend patient visits by an attending. All departments then developed and adopted a set of policy and education initiatives designed to increase prompt and consistent resident-attending communication (especially in critical events) and to improve regular attending visits with surgical patients. Specific reinforcement of the policies included a pocket information card for residents, as well as periodic reminders. Repeat audits of the surgical services were then conducted., Results: We reviewed information for 211 critical events and 1360 patients for the nature of resident and attending communication practices. After the intervention, the proportion of critical events not conveyed to an attending decreased from 33% (26/80) to 2% (1/47), and gaps in the frequency of attending notification of patient status on weekends were virtually eliminated (P < 0.0001); the proportion of weekend patients not visited by an attending for greater than 24 hours decreased by half (from 61% to 33%; P = 0.0002). Contact resulted in attending-led changes in patient management in one-third of cases., Conclusions: An intervention to improve surgical communication practices at 4 teaching hospitals led to significant reductions in potentially harmful communication breakdowns during inpatient care; significant alterations in patient management were noted in one-third of cases in which there was an adherence to recommended communication practices., ((C) 2011 Lippincott Williams & Wilkins, Inc.)

- Abstract
Objective: To evaluate whether Surgical Apgar Scores measure the relationship between intraoperative care and surgical outcomes., Summary Background Data: With preoperative risk-adjustment now well-developed, the role of intraoperative performance in surgical outcomes may be considered. We previously derived and validated a 10-point Surgical Apgar Score--based on intraoperative blood loss, heart rate, and blood pressure--that effectively predicts major postoperative complications within 30 days of general and vascular surgery. This study evaluates whether the predictive value of this score comes solely from patients' preoperative risk or also measures care in the operating room., Methods: Among a systematic sample of 4119 general and vascular surgery patients at a major academic hospital, we constructed a detailed risk-prediction model including 27 patient-comorbidity and procedure-complexity variables, and computed patients' propensity to suffer a major postoperative complication. We evaluated the prognostic value of patients' Surgical Apgar Scores before and after adjustment for this preoperative risk., Results: After risk-adjustment, the Surgical Apgar Score remained strongly correlated with postoperative outcomes (P < 0.0001). Odds of major complications among average-scoring patients (scores 7-8) were equivalent to preoperative predictions (likelihood ratio (LR) 1.05, 95% CI 0.78-1.41), significantly decreased for those who achieved the best scores of 9-10 (LR 0.52, 95% CI 0.35-0.78), and were significantly poorer for those with low scores--LRs 1.60 (1.12-2.28) for scores 5-6, and 2.80 (1.50-5.21) for scores 0-4., Conclusions: Even after accounting for fixed preoperative risk--due to patients' acute condition, comorbidities and/or operative complexity--the Surgical Apgar Score appears to detect differences in intraoperative management that reduce odds of major complications by half or increase them by nearly 3-fold.

- Abstract
Objective: To prospectively evaluate and accurately describe the rate and type of discrepancies encountered in the surgical count., Introduction: Despite near-universal implementation of manual counting protocols for surgical instruments and sponges, incidents of retained sponges and instruments (RSI) persist. Retrospective analyses have shown that RSI are rare and most often involve final counts erroneously thought to be correct, leading some surgeons to question the value of counting. Crucial data regarding how often the surgical count successfully detects meaningful problems before the patient leaves the operating room is lacking., Methods: Trained physician-observers documented prospective field observations during 148 elective general surgery operations using standardized intake forms. Data collection focused on the performance of the counting protocols, and the frequency and outcomes of discrepancies (instances in which a subsequent count does not agree with the previous count)., Results: A mean of 16.6 counting episodes occurred per case, occupying 8.6 minutes per case. A total of 29 discrepancies involving sponges (45%), instruments (34%) or needles (21%) were observed among 19 (12.8%) operations. Most discrepancies indicated a misplaced item (59%) as opposed to a miscount (3%) or error in documentation (38%). Each discrepancy took on average 13 minutes to resolve. Counting activities after personnel changes were significantly more likely to involve a discrepancy than those for which the original team was present., Conclusions: One in 8 surgical cases involves an intraoperative discrepancy in the count. The majority of these discrepancies detect unaccounted-for sponges and instruments, which represent potential RSI. Thus, despite the recognized limitations of manual surgical counts, discrepancies should always prompt a thorough search and reconciliation process and never be ignored.

- Abstract
Objective: A randomized, controlled trial was performed to evaluate a computer-assisted method for counting sponges using a bar-code system., Background: Retained sponges are a rare and preventable problem but persist in surgery despite standardized protocols for counting. Technology that improves detection of counting errors could reduce risk to surgical patients., Methods: We performed a randomized controlled trial comparing a bar-coded sponge system with a traditional counting protocol in 300 general surgery operations. Observers monitored sponge and instrument counts and recorded all incidents of miscounted or misplaced sponges. Surgeons and operating room staff completed postoperative and end-of-study surveys evaluating the bar-code system., Results: The bar-code system detected significantly more counting discrepancies than the traditional protocol (32 vs.13 discrepancies, P = 0.007). These discrepancies involved both misplaced sponges (21 vs. 12 sponges, P = 0.17) and miscounted sponges (11 vs. 1 sponge, P = 0.007). The system introduced new technical difficulties (2.04 per 1000 sponges) and increased the time spent counting sponges (5.3 vs. 2.4 minutes, P < 0.0001). In postoperative surveys, there was no difference in surgical teams' confidence that all sponges were accounted for, but they rated the counting process and team performance lower in operations randomized to the bar-code arm. By the end of the study, however, most providers found the system easy to use, felt confident in its ability to track sponges, and reported a positive effect on the counting process., Conclusions: Use of automated counting using bar-coded surgical sponges improved detection of miscounted and misplaced sponges and was well tolerated by surgical staff members.

- Abstract
Objective: To identify the most prevalent patterns of technical errors in surgery, and evaluate commonly recommended interventions in light of these patterns., Summary Background Data: The majority of surgical adverse events involve technical errors, but little is known about the nature and causes of these events. We examined characteristics of technical errors and common contributing factors among closed surgical malpractice claims., Methods: Surgeon reviewers analyzed 444 randomly sampled surgical malpractice claims from four liability insurers. Among 258 claims in which injuries due to error were detected, 52% (n = 133) involved technical errors. These technical errors were further analyzed with a structured review instrument designed by qualitative content analysis., Results: Forty-nine percent of the technical errors caused permanent disability; an additional 16% resulted in death. Two-thirds (65%) of the technical errors were linked to manual error, 9% to errors in judgment, and 26% to both manual and judgment error. A minority of technical errors involved advanced procedures requiring special training ("index operations"; 16%), surgeons inexperienced with the task (14%), or poorly supervised residents (9%). The majority involved experienced surgeons (73%), and occurred in routine, rather than index, operations (84%). Patient-related complexities-including emergencies, difficult or unexpected anatomy, and previous surgery-contributed to 61% of technical errors, and technology or systems failures contributed to 21%., Conclusions: Most technical errors occur in routine operations with experienced surgeons, under conditions of increased patient complexity or systems failure. Commonly recommended interventions, including restricting high-complexity operations to experienced surgeons, additional training for inexperienced surgeons, and stricter supervision of trainees, are likely to address only a minority of technical errors. Surgical safety research should instead focus on improving decision-making and performance in routine operations for complex patients and circumstances.
