Neck hematoma after major head and neck surgery: Risk factors, costs, and resource utilization.

BACKGROUND: Postoperative cervical hematoma after major head and neck surgery is a feared complication. However, risk factors for developing this complication and attributable costs are not well-established. METHODS: The Nationwide Inpatient Sample database was utilized compare patients with and without postoperative cervical hematoma. Logistic regression was used to analyze risk factors for hematoma formation and 30-day mortality. Total inpatient length of stay (LOS) and costs were fit to generalized linear models. RESULTS: Of 32 071 patients, 1098 (3.4%) experienced a postoperative cervical hematoma. Male sex (odds ratio [OR] 1.38; P < .0001), black race (OR 1.35; P = .010), 4 or more comorbidities (OR 1.66; P < .0001), or presence of a preoperative coagulopathy (OR 6.76; P < .0001) were associated. Postoperative cervical hematoma was associated with 540% increased odds of death (P < .0001). The LOS and total excess costs were 5.14 days (P < .0001) and $17 887.40 (P < .0001), respectively. CONCLUSION: Although uncommon, postoperative cervical hematoma is a life-threatening complication of head and neck surgery with significant implications for outcomes and resource utilization.

Successful percutaneous access for endovascular aneurysm repair is significantly cheaper than femoral cutdown in a prospective randomized trial.

OBJECTIVE: Because of its minimally invasive nature, percutaneous femoral access for endovascular aneurysm repair (pEVAR) is currently undergoing rapid popularization. Compared with surgical cutdown for femoral access (cEVAR), it offers the advantage of faster recovery after surgery as well as a reduction in wound complications. Despite proposed advantages, the method is largely considered uneconomical because of its reliance on costly closure devices. METHODS: There were 50 patients undergoing EVAR who were enrolled in this randomized prospective single-center trial. Each patient randomly received percutaneous access in one groin and surgical access in the other. The primary end points were access duration and cost. Secondary end points were wound complications and the postoperative pain levels. RESULTS: Surgery was performed per protocol in 44 patients. Mean access times for pEVAR and cEVAR were 11.5 ± 3.4 minutes and 24.8 ± 12.1 minutes (P < .001), respectively. Total access costs were €559.65 ± €112.69 for pEVAR and €674.85 ± €289.55 for cEVAR (P = .016). Eight complications in six patients were attributed to cutdown, none to pEVAR (P = .02). The percutaneously accessed groin was significantly less painful at day 1 and day 5 after surgery (P < .001). An intention-to-treat analysis (N = 50 patients) included six cases of pEVAR conversion due to technical failure in three patients (6%) and change of the operative strategy in another three patients (eg, aortouni-iliac stent graft followed by crossover bypass). The intention-to-treat analysis showed shorter mean overall access time for pEVAR (pEVAR, 14.65 ± 10.20 minutes; cEVAR, 25.12 ± 11.77 minutes; P < .001) and no cost difference between the two methods (pEVAR, €651.29 ± €313.49; cEVAR, €625.53 ± €238.29; P = .65). CONCLUSIONS: Our data confirm proposed potential benefits attributable to the minimally invasive nature of pEVAR while demonstrating cost-effectiveness despite the additional cost of closure devices. Taking into account pEVAR failures still does not increase pEVAR costs over cEVAR. Further considering reduced postoperative pain and wound complications, the technique deserves consideration in suitable patients.

Resource utilization associated with cervical hematoma after thyroid and parathyroid surgery.

BACKGROUND: Postoperative cervical hematoma (PCH) after thyroid and parathyroid surgery is a well-known complication. This study used data from the Nationwide Inpatient Sample to identify risk factors, estimate mortality, length of stay (LOS), and total costs attributable to PCH in patients undergoing procedures for thyroid and parathyroid diseases. METHODS: Patients aged >18 y who underwent thyroid or parathyroid surgery between 2001 and 2011 were identified and stratified by the occurrence of PCH. Univariate analyses of patient demographics, clinical and hospital characteristics were performed. Multivariable logistic regression was used to determine risk factors for hematoma formation. LOS and costs were fit to linear regression models to determine the effect of PCH after adjusting for patient and hospital characteristics. RESULTS: Of patients who underwent thyroid or parathyroid surgery, 619 patients (0.8%) had a PCH. Predisposing factors included nonelective admission (emergent: OR = 2.01, P < 0.0001; urgent: OR = 1.47, P = 0.003), diagnosis of Graves' disease (OR = 1.90, P < 0.0001), or other benign pathology (OR = 1.43, P = 0.011) and having ≥2 comorbidities (2-3 comorbidities, OR = 1.24; P = 0.036 and ≥ 4 comorbidities, OR = 2.28; P < 0.0001). After adjusting for those characteristics, the total excess LOS and costs attributable to PCH were 2.1 d (P < 0.0001) and $7316 (P < 0.0001), respectively. In addition, after risk adjustment, odds of mortality more than tripled (P < 0.0001) in the setting of PCH. CONCLUSIONS: Because risk for PCH is largely driven by preoperative patient risk factors, five clinicians have an opportunity to stratify patients accordingly and thereby minimize the resource utilization and health care spending among those with lowest risk.

Risks and benefits of opportunistic salpingectomy during vaginal hysterectomy: a decision analysis.

BACKGROUND: Fallopian tubes are commonly removed during laparoscopic and open hysterectomy to prevent ovarian and tubal cancer but are not routinely removed during vaginal hysterectomy because of perceptions of increased morbidity, difficulty, or inadequate surgical training. OBJECTIVE: We sought to quantify complications and costs associated with a strategy of planned salpingectomy during vaginal hysterectomy. STUDY DESIGN: We created a decision analysis model using TreeAgePro. Effectiveness outcomes included ovarian cancer incidence and mortality as well as major surgical complications. Modeled complications included transfusion, conversion to laparotomy or laparoscopy, abscess/hematoma requiring intervention, ileus, readmission, and reoperation within 30 days. We also modeled subsequent benign adnexal surgery beyond the postoperative window. Those whose procedures were converted from a vaginal route were assumed to undergo bilateral salpingectomy, regardless of treatment group, following American College of Obstetricians and Gynecologists guidelines. Costs were gathered from published literature and Medicare reimbursement data, with internal cost data from 892 hysterectomies at a single institution used to estimate costs when necessary. Complication rates were determined from published literature and from 13,397 vaginal hysterectomies recorded in the National Surgical Quality Improvement Program database from 2008 through 2013. RESULTS: Switching from a policy of vaginal hysterectomy alone to a policy of routine planned salpingectomy prevents a diagnosis of ovarian cancer in 1 of every 225 women having surgery and prevents death from ovarian cancer in 1 of every 450 women having surgery. Overall, salpingectomy was a less expensive strategy than not performing salpingectomy ($7350.62 vs $8113.45). Sensitivity analysis demonstrated the driving force behind increased costs was the increased risk of subsequent benign adnexal surgery among women retaining their tubes. Planned opportunistic salpingectomy had more major complications than hysterectomy alone (7.95% vs 7.68%). Major complications included transfusion, conversion to laparotomy or laparoscopy, abscess/hematoma requiring intervention, ileus, readmission, and reoperation within 30 days. Therefore, routine salpingectomy results in 0.61 additional complications per case of cancer prevented and 1.21 additional complications per death prevented. A surgeon therefore must withstand an additional ∼3 complications to prevent 5 cancer diagnoses and ∼6 additional complications to prevent 5 cancer deaths. CONCLUSION: Salpingectomy should routinely be performed with vaginal hysterectomy because it was the dominant and therefore cost-effective strategy. Complications are minimally increased, but the trade-off with cancer prevention is highly favorable.

Mortality, Length of Stay, and Cost Implications of Procedural Bleeding After Percutaneous Interventions Using Large-Bore Catheters.

Importance: Bleeding complications after percutaneous transcatheter interventions that used large-bore catheters are frequent and associated with high mortality and morbidity. Objective: To describe the incidence of bleeding complications among patients undergoing contemporary endovascular interventions involving large-bore catheters and its association with in-hospital mortality, length of stay, and health care cost. Design, Setting, and Participants: This retrospective cohort study analyzed all 17 672 patients from the Healthcare Cost and Utilization Project's National Inpatient Sample database who were recorded as having undergone a transcatheter aortic valve replacement (n = 3223), an endovascular aneurysm repair (n = 12 633), or a percutaneous left ventricular assist device implant (n = 1816) between January 1, 2012, and December 31, 2013. Bleeding complication was defined as any transfusion, any hemorrhage or hematoma, or the need for percutaneous or surgical intervention to control the bleeding event. Health care costs were determined by multiplying the total charge for each visit by the cost to charge ratios reported for each hospital code in the database. Data were collected from the database on April 29, 2016. Main Outcomes and Measures: Adjusted association between bleeding complications and mortality was determined by multivariable logistic regression. Length of stay and total health care costs were compared using multivariable linear regression between patients who did and patients who did not have bleeding complications. Results: Bleeding complications occurred in 3128 patients (17.7%) (1984 men and 1144 women, with a mean [SD] age of 75.6 [11.9] years). Bleeding was associated with higher mortality (adjusted odds ratio, 2.70; 95% CI, 2.27-3.22; P < .001) and longer hospital stay (adjusted multiplicative difference, 2.14; 95% CI, 2.06-2.16; P < .001). Median (interquartile range) total health care costs were $48 663 ($32 620-$71 547) for patients with bleeding complications compared with $29 968 ($21 924-$43 287) for patients without a bleeding complication (adjusted multiplicative difference, 1.55; 95% CI, 1.52-1.59; P < .001). Conclusions and Relevance: Periprocedural bleeding was common among patients who underwent transcatheter intervention using large-bore catheters and was associated with a statistically significant increase in mortality, length of stay, and cost.

Early Surgery versus Initial Conservative Treatment in Patients with Traumatic Intracerebral Hemorrhage (STITCH[Trauma]): The First Randomized Trial.

Intraparenchymal hemorrhages occur in a proportion of severe traumatic brain injury TBI patients, but the role of surgery in their treatment is unclear. This international multi-center, patient-randomized, parallel-group trial compared early surgery (hematoma evacuation within 12 h of randomization) with initial conservative treatment (subsequent evacuation allowed if deemed necessary). Patients were randomized using an independent randomization service within 48 h of TBI. Patients were eligible if they had no more than two intraparenchymal hemorrhages of 10 mL or more and did not have an extradural or subdural hematoma that required surgery. The primary outcome measure was the traditional dichotomous split of the Glasgow Outcome Scale obtained by postal questionnaires sent directly to patients at 6 months. The trial was halted early by the UK funding agency (NIHR HTA) for failure to recruit sufficient patients from the UK (trial registration: ISRCTN19321911). A total of 170 patients were randomized from 31 of 59 registered centers worldwide. Of 82 patients randomized to early surgery with complete follow-up, 30 (37%) had an unfavorable outcome. Of 85 patients randomized to initial conservative treatment with complete follow-up, 40 (47%) had an unfavorable outcome (odds ratio, 0.65; 95% confidence interval, CI 0.35, 1.21; p=0.17), with an absolute benefit of 10.5% (CI, -4.4-25.3%). There were significantly more deaths in the first 6 months in the initial conservative treatment group (33% vs. 15%; p=0.006). The 10.5% absolute benefit with early surgery was consistent with the initial power calculation. However, with the low sample size resulting from the premature termination, we cannot exclude the possibility that this could be a chance finding. A further trial is required urgently to assess whether this encouraging signal can be confirmed.

Comparison of the Tada formula with software slicer: precise and low-cost method for volume assessment of intracerebral hematoma.

BACKGROUND AND PURPOSE: The Tada (ABC/2) formula has been used widely for volume assessment of intracerebral hematoma. However, the formula is crude for irregularly shaped hematoma. We aimed to compare the accuracy of the ABC/2 formula with open source software Slicer. METHODS: Computed tomographic images of 294 patients with spontaneous intracerebral hematoma were collected. Hematoma volumes were assessed with the ABC/2 formula and calculated with software 3D Slicer. Results of these 2 methods were compared with regard to hematoma size and shape. RESULTS: The estimated hematoma volume was 58.41±37.83 cm(3) using the ABC/2 formula, compared with 50.38±31.93 cm(3) with 3D Slicer (mean percentage deviation, 16.38±9.15%). When allocate patients into groups according to hematoma size, the mean estimation error were 3.24 cm(3) (17.72%), 5.85 cm(3) (13.72%), and 15.14 cm(3) (17.48%) for groups 1, 2, and 3, respectively. When divided by shape, estimation error was 3.33 cm(3) (9.76%), 7.19 cm(3) (18.37%), and 29.39 cm(3) (39.12%) for regular, irregular, and multilobular hematomas. CONCLUSIONS: There is significant estimation error using the ABC/2 formula to calculate hematoma volume. Compared with hematoma size, estimation error is more significantly associated with hematoma shape.

Risk factors, causes, and the economic implications of unplanned readmissions following total hip arthroplasty.

In order to identify risk factors for readmissions following total hip arthroplasty (THA) and the causes and financial implications of such readmissions, we analyzed clinical and administrative data on 1583 consecutive primary THAs performed at a single institution. The 30-day readmission rate was 6.51%. Increased age, length of stay, and body mass index were associated with significantly higher readmission rates. The most common re-admitting diagnoses were deep infection, pain, and hematoma. Average profit was lower for episodes of care with readmissions ($1548 vs. $2872, P=0.028). If Medicare stops reimbursing for THA readmissions, the institution under review would sustain an average net loss of $11,494 for episodes of care with readmissions and would need to maintain readmission rates below 23.6% in order to remain profitable.

Female gender and oral anticoagulants are associated with wound complications in lower extremity vein bypass: an analysis of 1404 operations for critical limb ischemia.

BACKGROUND: Infrainguinal bypass (IB) surgery is an effective means of improving arterial circulation to the lower extremity for patients with critical limb ischemia (CLI). However, wound complications (WC) of the surgical incision following IB can impart significant morbidity. METHODS: A retrospective analysis of WC from the 1404 patients enrolled in a multicenter clinical trial of vein bypass grafting for CLI was performed. Univariate and multivariable regression models were used to determine WC predictors and associated outcomes, including graft patency, limb salvage, quality of life (QoL), resource utilization (RU), and mortality. RESULTS: A total of 543 (39%) patients developed a reported WC within 30 days of surgery, with infections (284, 52%) and hematoma/hemorrhage (121, 22%) being the most common type. Postoperative anticoagulation (odds ratio [OR], 1.554; 95% confidence interval [CI] 1.202 to 2.009; P = .0008) and female gender (OR, 1.376; 95% CI, 1.076 to 1.757; P = .0108) were independent factors associated with WC. Primary, primary-assisted, and secondary graft patency rates were not influenced by the presence of WC; though, patients with WC were at increased risk for limb loss (hazard ratio [HR], 1.511; 95% CI 1.096 to 2.079; P = .0116) and higher mortality (HR, 1.449; 95% CI 1.098 to 1.912; P = .0089). WC was not significantly associated with lower QoL at 3 months (4.67 vs 4.79, P = .1947) and 12 months (5.02 vs 5.13, P = .2806). However, the subset of patients with serious WC (SWC) demonstrated significantly lower QoL at 3 months compared with patients without WC, (4.43 vs 4.79, respectively, P = .0166), though this difference was not seen at 12 months (4.94 vs 5.13, P = .2411). Patients with WC had higher RU than patients who did not have WC. Mean index length of hospital stay (LOS) was 2.3 days longer, mean cumulative 1-year LOS was 8.1 days longer, and mean number of hospitalizations was 0.5 occurrences greater for patients with WC compared with patients without WC (all P < .0001). CONCLUSIONS: WC is a frequent complication of IB for CLI, associated with increased risk for major amputation, mortality, and greater RU. Further detailed investigation into the link between female gender and oral anticoagulation use with WC may help identify causes of WC and perhaps prevent or lessen their occurrence.

Comparison of nail bed repair versus nail trephination for subungual hematomas in children.

Fifty-three fingers in 52 children were divided into 2 groups, operative and nonoperative, after fingernail crush injury. Criteria for inclusion into the study were an intact nail and nail margin with subungual hematoma and no previous nail abnormality. The length of the follow-up period averaged longer than 2 years for each group. Twenty-six fingers in 26 children were treated by nail removal, exploration, and repair of nail bed lacerations (operative group). Twenty-seven fingers in 26 children were treated by evacuation of hematoma by nail trephination without nail removal in 11 fingers and by observation in the other 16 fingers (nonoperative group). In the operative group, transient abnormalities (nail depression or hypertrophy), which resolved by 4 months, occurred in 3 patients. In the group treated by simple decompression, there were no complications except for 1 transient nail depression at 3 months. The average cost to the operative group was $1,263 compared with $283 to the trephination group. Although formal nail bed reconstruction has been advocated for hematomas larger than 25%, we found no notable difference in outcome between the 2 groups regardless of hematoma size, presence of fracture, injury mechanism, or age. Charges, however, were 4 times greater for the operative group. Based on the results of this study, we do not feel that nail removal and nail bed exploration is indicated or justified for children with subungual hematoma and an intact nail and nail margin.

Use of a collagen hemostatic closure device to achieve hemostasis after arterial puncture: a cost-effectiveness analysis.

PURPOSE: To evaluate whether a collagen hemostatic closure device is a safe, cost-effective alternative to manual compression for achieving hemostasis at arterial puncture sites. MATERIALS AND METHODS: A cost-effectiveness analysis, based on a meta-analysis of published data, was performed from the perspective of the health-care system. The gain in effectiveness was expressed as the decrease in rate of puncture-site complications that required treatment. Costs associated with achieving hemostasis and treating complications were included. RESULTS: Use of a collagen closure device decreased the number of puncture-site complications from 31:1,000 to 16:1,000. The average cost of using the device was $177 per patient compared with $42 per patient for manual compression. The incremental cost of averting one complication exceeded $9,000. CONCLUSION: Use of a collagen closure device to achieve hemostasis after an arterial puncture may reduce the complication rate, but the additional cost per complication averted is very high.
