Impact of a clinical pathway for elective infrarenal aortic reconstructions.

OBJECTIVE: To determine the impact of a clinical pathway for elective infrarenal aortic reconstruction on outcome, resource utilization, and cost in a university medical center. SUMMARY BACKGROUND DATA: Clinical pathways have been reported to control costs, reduce resource utilization, and maintain or improve the quality of patient care, although their use during elective aortic reconstructions remains unresolved. METHODS: A clinical pathway was developed for elective infrarenal aortic reconstructions by a multidisciplinary group comprised of representatives from each involved service. The prepathway practice and costs were analyzed and an efficient, cost-effective practice with specific outcome measures was defined. The impact of the pathway was determined by retrospective comparison of outcome, resource utilization, and cost (total and direct variable) between the pathway patients (PATH, n = 45) and a prepathway control group (PRE, n = 20). RESULTS: There were no significant differences in the patient demographics, comorbid conditions, operative indications, or type of reconstruction between the groups. There were no operative deaths and the overall complication rate (PRE, 35% vs. PATH, 34%) was similar. The pathway resulted in significant decreases in the total length of stay and preoperative length of stay and a trend toward a significant decrease (p = 0.08) in the intensive care length of stay for the admission during which the operation was performed. The pathway also resulted in significant decreases in both direct variable and total hospital costs for this admission, as well as a significant decrease in the overall direct variable and total hospital costs for the operative admission and the preoperative evaluation (< or =30 days before operative admission). Despite these reductions, the discharge disposition, 30-day readmissions, and number of postoperative clinic visits within 90 days of discharge were not different. CONCLUSIONS: Implementation of a clinical pathway for elective infrarenal aortic reconstructions dramatically decreased resource utilization and hospital costs without affecting the quality of patient care and did not appear to shift the costs to another setting.     

The impact of a clinical pathway for gastric bypass surgery on resource utilization

BACKGROUND: Clinical pathways are believed to improve patient care and reduce costs. Our hypothesis was that a gastric bypass pathway would decrease hospital resource utilization and cost of care without adversely affecting patient care. METHODS: The prepathway (Pre) group consisted of 16 gastric bypasses (6/98 to 3/99). The postpathway (Post) group includes 12 gastric bypass procedures performed after institution of the clinical pathway (4/99 to 12/99). The impact of the clinical pathway on hospital length of stay (LOS) and resource utilization was investigated. A comparison of costs was performed using cost/charge ratios. Hospital readmissions and postoperative complications were also examined. RESULTS: Despite increased obesity/medical acuity of the Post group, hospital LOS decreased by 3 days (P < 0.0001). Total hospital costs decreased by over $1600/case (>15%). Postpathway savings were greatest for room and board (34%), supplies (41%), and lab/radiology costs (50%). An increase in OR costs (22%) was observed in the Post group. This was due to an increase in anesthesia time (epidural catheter placement) and equipment costs (ultrasonic shears). Despite reductions in hospital LOS and resource utilization, the complication rate (Pre 12%, Post 16%) was similar and two patients in each group required brief readmission. CONCLUSIONS: A pathway for gastric bypass decreased hospital LOS and resource utilization. OR-related expenses account for 34-50% of total costs and must be monitored closely for surgical patients. The reduction in costs observed with this clinical pathway was not associated with an increase in postoperative complications or hospital readmission.     

Clinical pathway management of total knee arthroplasty: a retrospective comparative study

BACKGROUND: Clinical pathways facilitate the management of defined patient groups using interdisciplinary plans of care. The aim of the present study was to evaluate the effectiveness of a clinical pathway in improving a range of selected outcome measures in patients who have undergone total knee arthroplasty (TKA). METHODS: The present study was conducted at Queen Elizabeth Hospital, Adelaide. Using a retrospective comparative study design, 119 TKA patients who were managed on a clinical pathway from July 1997 to January 1998 (group 2) were compared with a retrospective group of 58 patients who underwent the same procedure from July 1996 to January 1997 (group 1) prior to the pathway's implementation. The following outcomes were measured: length of hospital stay; postoperative complications; readmissions and emergency service visits within 6 months of discharge; day of transfer to the convalescent unit; convalescent unit utilization and admission and discharge times. RESULTS: There was a significant reduction in the median length of stay in group 2 patients (9 vs 7 days; P < 0.0001). In addition there was a 66% increase in the proportion of patients in group 2 who were admitted on the day of surgery (P < 0.0001) and a 19.6% increase in the number of patients discharged within 8 postoperative days (P < 0.01). There were no significant differences between the groups with respect to the occurrence of postoperative complications. Although there was a trend toward a reduction in emergency service utilization and readmissions within 6 months of discharge for patients managed on the pathway, this was not significant. CONCLUSIONS: The development and implementation of a TKA clinical pathway resulted in a significant reduction in length of stay and improved streamlining of admission, discharge and transfer processes without adversely affecting patient outcomes.     

Demand Matching Total Joint Replacement Patients Results in Reduction of Post-Discharge Costs

BackgroundThe shift from fee-for-service to value-based care has focused payers and providers on resource utilization. One important component of value-based care is to reduce the use of post-discharge (PD) services in a clinically appropriate manner following total joint arthroplasty (TJA). Demand matching in healthcare is the process of tailoring appropriate medical care to a patient with respect to that patient’s specific medical needs and social determinants. Outcomes following the implementation of a demand-matching algorithm for coordinating PD services after TJA were analyzed in this study.MethodsPayment data from all Medicare patients undergoing primary unilateral TJA between July 2014 and December 2018 from a single orthopedic practice were included. These payments were separated into acute and PD care. The initial acute and PD costs were compared to costs at the end of the 4-year study period using multiple linear regression and chi-square.ResultsA total of 9,638 patients (4,212 total hip arthroplasties and 5,430 total knee arthroplasties) were included. Acute costs of TJA were stable averaging $13,712.00. PD costs fell steadily from a baseline average of $7,319.00 in July 2014 to $4,678.00 in December 2018 (P < .001), representing a 36.1% decline. Discharge to home increased steadily from 45.8% to 79.9% during the same interval (P < .001.)ConclusionOur results demonstrate a statistically significant reduction in PD costs over a 4-year period using a demand-matching strategy to align with the Centers for Medicare and Medicaid Services mandate for value-based care. Based on these data, we conclude that thoughtful preoperative assessment of patient factors such as social determinants and medical comorbidities could allow for cost reduction through better utilization of PD services.     

Outpatient laparoscopic cholecystectomy: patient outcomes after implementation of a clinical pathway

OBJECTIVE: To determine the success of a clinical pathway for outpatient laparoscopic cholecystectomy (LC) in an academic health center, and to assess the impact of pathway implementation on same-day discharge rates, safety, patient satisfaction, and resource utilization. SUMMARY BACKGROUND DATA: Laparoscopic cholecystectomy is reported to be safe for patients and acceptable as an outpatient procedure. Whether this experience can be translated to an academic health center or larger hospital is uncertain. Clinical pathways guide the care of specific patient populations with the goal of enhancing patient care while optimizing resource utilization. The effectiveness of these pathways in achieving their goals is not well studied. METHODS: During a 12-month period beginning April 1, 1999, all patients eligible for an elective LC (n = 177) participated in a clinical pathway developed to transition LC to an outpatient procedure. These were compared with all patients undergoing elective LC (n = 208) in the 15 months immediately before pathway implementation. Successful same-day discharges, reasons for postoperative admission, readmission rates, complications, deaths, and patient satisfaction were compared. Average length of stay and total hospital costs were calculated and compared. RESULTS: After pathway implementation, the proportion of same-day discharges increased significantly, from 21% to 72%. Unplanned postoperative admissions decreased as experience with the pathway increased. Patient characteristics, need for readmission, complications, and deaths were not different between the groups. Patients surveyed were highly satisfied with their care. Resource utilization declined, resulting in more available inpatient beds and substantial cost savings. CONCLUSIONS: Implementation of a clinical pathway for outpatient LC was successful, safe, and satisfying for patients. Converting LC to an outpatient procedure resulted in a significant reduction in medical resource use, including a decreased length of stay and total cost of care.     

The Effect of Psychiatric Diagnosis and Psychotropic Medication on Outcomes Following Total Hip and Total Knee Arthroplasty

BackgroundNearly 20% of the US adult population lives with mental illness, and less than 50% of these receive treatment. Preoperative mental health may affect postoperative outcomes in patients undergoing total joint arthroplasty (TJA), yet is rarely addressed; poor outcomes increase the cost of care and burden on the healthcare system. This study examines the influence of patients with psychiatric diagnosis (PD) and taking psychotropic medication (PM) on emergency room visits, readmissions, and discharge disposition following TJA.MethodsSingle institution retrospective analysis of a consecutive series of 3020 primary TJA performed between January 2017 and June 2018. Chi-squared, t-tests, and analysis of variance were used to quantify differences between groups.ResultsNine hundred seventy-six (32.3%) patients had a PD, most had depression (10.1%), anxiety (8.6%), or both (8.4%); 808 (26.8%) patients were on PM. Patients with PD were more likely to experience emergency room visits (6.3% vs 10.0%, P = .034) and skilled nursing facility discharge (11.6% vs 17.9%, P = .005). Patients taking PM were more likely to experience skilled nursing facility discharge (12.4 vs 17.1, P = .047); those taking >2 PM had the highest rate (21.6%).ConclusionPatients with PD on or off PM may experience increased healthcare utilization in the postoperative period. Increased patient education and support may reduce these discrepancies. PD is not a deterrent for TJA, but targeted interventions should be developed to provide additional support where needed and avoid unnecessary utilization of resources.     

Analysis of Cost Outliers after Gastric Bypass Surgery: What can we Learn?

Background: A clinical pathway for gastric bypass surgery (GBS) implemented at our institution in 1999 resulted in reduced costs and decreased variability in patient care. However, a reanalysis of GBS hospital costs identified a 16% incidence of"cost outliers".We hypothesized that analysis of clinical variables would identify factors associated with increased hospital costs following GBS. Methods: Medical records and financial data for 91 GBS patients from November 2000 to July 2001 were reviewed. Patients with costs >1 SD above the total hospital cost mean comprised the cost outlier (CO) group, while the remaining patients were considered the normal cost (NC) group. Potential etiologies for COs included patient demographics, the number and severity of medical co-morbidities, surgical factors, and major postoperative complications. Results: There were 15 patients in the CO group, and 76 patients in the NC group. Patient demographics were similar in both groups. Diabetes mellitus and severe medical co-morbidities, especially sleep apnea and degenerative joint disease were more common in the CO group (60% vs 9.2%, P<0.05 vs NC).The incidence of major complications (33% vs 8%) was significantly increased in the CO group (P<0.05 vs NC). Conclusions: Despite utilization of a clinical pathway for GBS, 16% of patients were "cost outliers". Factors associated with increased hospital costs after GBS included severe medical co-morbidities (especially diabetes mellitus and sleep apnea) and the occurrence of major postoperative complications. Prospective identification of "high risk" GBS patients may allow hospitals with bariatric surgery programs to modify perioperative care and eliminate potential cost outliers.     

A Web-Based Interactive Patient-Provider Software Platform Does Not Increase Patient Satisfaction or Decrease Hospital Resource Utilization in Total Knee and Hip Arthroplasty Patients in a Single Large Hospital System

BackgroundWeb-based platforms used to enhance patient-provider communication are being explored to improve patient satisfaction and care delivery, and decrease cost. This study tested a web-based interactive patient-provider software platform (IPSP), JointCOACH, which enabled patient communication with their care team and preparatory/recovery guidance. The aims of this study are to compare (1) patient satisfaction and (2) healthcare resource utilization by patients who underwent total knee and hip replacements and added IPSP to standard of care (SOC).MethodsThis study is a prospective, randomized clinical trial at a single large academic healthcare system. Between May 2018 and March 2020, 399 patients undergoing elective total hip or knee arthroplasty were randomized to SOC arm (n = 204) or SOC + IPSP arm (n = 195). Patient demographics, surgical details, and comorbidities were collected. Patient satisfaction was assessed using Visual Analog Scale and the Picker Patient Experience-15. Healthcare utilization was measured using length of stay, emergency department and office visits, office calls, readmissions, and reoperations at 30 and 90 days after surgery.ResultsNo difference was found in length of stay between SOC and SOC + IPSP. No differences were found in 30-day or 90-day satisfaction or in healthcare resource utilization (P > .05) including number of office and emergency department visits, phone calls, and readmissions.ConclusionStatistical differences were not found in satisfaction and healthcare utilization with the addition of IPSP to SOC. IPSP can be used to reinforce patient education and communication between the patient and provider, and should be evaluated as an element of virtual care rather than supplementing traditional in-office follow-up.Clinicaltrials.govMore information on this study can be found at clinicaltrials.gov NCT03499028.     

Conversion Total Knee Arthroplasty is Associated with Increased Post-Acute Care Costs

BackgroundAlternative payment models have been viewed as successfully decreasing costs following primary total knee arthroplasty (TKA) while maintaining quality. Concerns exist regarding access to care for patients who may utilize more resources in a bundled payment arrangement. The purpose of this study is to determine if patients undergoing conversion of prior surgery to TKA have increased costs compared to primary TKA patients.MethodsClaims from Medicare and a single private insurer were queried for all primary TKA patients at our institution from 2015 to 2016. Ninety-day post-acute care costs were compared between primary and conversion TKA. Secondary endpoints included discharge disposition, complications, and readmissions. A multivariate regression analysis was performed to identify independent risk factors for increased post-acute care costs and short-term outcome metrics.ResultsOf 3999 primary TKA procedures, 948 patients (23%) underwent conversion TKA. Conversion TKA was associated with greater post-acute care costs in patients with commercial insurance ($4714 vs $3759, P = .034). Among Medicare beneficiaries, prior ligament reconstruction was associated with increased post-acute care costs ($1917 increase, P = .036), while prior fracture fixation approached statistical significance ($2402 increase, P = .055). Conversion TKA was an independent risk factor for readmissions (odds ratio 1.46, 95% confidence interval 1.00-2.17, P = .050), while patients with a prior open knee procedure had higher rates of complications (odds ratio 2.41, 95% confidence interval 1.004-5.778, P = .049).ConclusionOur data suggest that conversion from prior knee surgery to TKA is associated with increased 90-day post-acute care costs and resource utilization, particularly prior open procedures. Without appropriate risk adjustment in alternative payment models, surgeons may be financially deterred from providing quality arthroplasty care given the reduced net payment and surgical complexity of such cases.     

Are We at the Bottom? BPCI Programs Now Disincentivize Providers Who Maintain Quality Despite Caring for Increasingly Complex Patients

BackgroundThe Bundled Payments for Care Improvement (BPCI) initiative has been successful at reducing Medicare costs after total joint arthroplasty (TJA). Target pricing is based on each institution's historical performance and is periodically reset. The purpose of this study was to examine the performance of our BPCI program accounting for patient complexity, quality, and resource utilization.MethodsWe reviewed a consecutive series of 9195 Medicare patients undergoing primary TJA from 2015 to 2018. Demographics, comorbidities, and readmissions by year were compared. We then examined 90-day episode-of-care costs, changes in target price, and financial margins during the duration of the BPCI program using Medicare claims data.ResultsPatients undergoing TJA in 2018 had a higher prevalence of diabetes and cardiac disease (all P < .001) as compared with those in 2015. From 2015 to 2018, there was a decrease in the rate of discharge to rehabilitation facilities (23% vs 14%, P < .001) and length of stay (2.1 vs 1.7 days, P < .001) with no difference in readmissions (6% vs 6%, P = .945). There was a reduction in postacute care costs ($6076 vs $4,890, P < .001) and 90-day episode-of-care costs ($19,954 vs $18,449, P < .001). However, the target price also decreased ($22,280 vs $18,971, P < .001), and the per-patient margin diminished ($2683 vs $522, P < .001).ConclusionSurgeons have maintained quality of care at a reduced cost despite increasing patient complexity. The target price adjustments resulted in declining margins during the course of our BPCI experience. Policy makers should consider changes to target price methodology to encourage participation in these successful cost-saving programs.     

African American Patients Have Improved Functional Gains and Comparable Clinical Outcomes to Caucasian Patients After Total Hip and Knee Arthroplasty

BackgroundWith the increasing popularity of alternative payment models, minorities who use more postacute care resources may face difficulties with access to quality total hip arthroplasty (THA) and total knee arthroplasty (TKA) care. The purpose of this study is to compare differences in perioperative complications and functional outcomes between African American and Caucasian patients undergoing THA and TKA.MethodsWe reviewed a consecutive series of all primary THA and TKA patients at our institution from 2015 to 2018. Demographics, comorbidities, 90-day complications, readmissions, Veterans Rand 12-Item Health Survey (VR-12), Hip disability Osteoarthritis Outcome Score (HOOS), and Knee injury and Osteoarthritis Outcome Scores (KOOS) were compared between African American and Caucasian patients. A multivariate analysis was performed to control for confounding variables.ResultsOf the 5284 patients included in the study, 1041 were African American (24.5%). Although African American patients had lower preoperative HOOS/KOOS (33.5 vs 45.1, P < .001) and mental VR-12 scores (37.8 vs 51.5, P < .001) compared with Caucasian patients, there was no clinical difference at 1 year in HOOS/KOOS (50.2 vs 50.4), mental VR-12 (55.0 vs 52.6), or physical VR-12 scores (39.5 vs 39.8). When controlling for demographics and medical comorbidities, African American race was associated with increased rehabilitation facility discharge (odds ratio, 1.69; P < .001) but no difference in readmissions or complications.ConclusionAlthough African American patients had lower preoperative functional scores, they made improved postoperative gains when compared with Caucasian patients. Although there was no difference in postoperative complications, further studies should assess social causes for the increase in rehabilitation utilization rates in minority patients.     

A clinical pathway for laparoscopic pyeloplasty decreases length of stay

PURPOSE: Benefits of minimally invasive procedures include decreased hospitalization and recovery times. Decreased length of stay (LOS) improves hospital efficiency and decreases costs. However, decreasing the LOS at the expense of patient care and satisfaction is not acceptable. A clinical pathway (CP) with structured order sets and imaging was developed for patients undergoing laparoscopic pyeloplasty. This pathway includes a cascade of activities managed closely by the health care team. This study assesses the safety and patient satisfaction with this clinical pathway. MATERIALS AND METHODS: We reviewed all adult pyeloplasties (39) completed laparoscopically since November 2001. All patients were managed according to the CP developed for the laparoscopic pyeloplasty procedure. The length of stay was measured in days. Patient satisfaction was assessed with a standardized questionnaire. Any readmissions or emergency room visits were documented. RESULTS: The mean length of stay was 1.10 days. Of 39 patients 37 (94%) were discharged home on postoperative day 1. One patient with severe postoperative pain required intravenous analgesia. She had undergone complex upper tract reconstruction and stayed a total of 4 days. One patient, who had a previous failed endopyelotomy, remained 2 days for persistent nausea. No patients sought emergency room consultation and there were no readmissions. Of 39 patients 34 (87%) completed the questionnaire and satisfaction was high. CONCLUSIONS: The implementation of a CP at our institution has standardized patient care in this population and decreased LOS in comparison to the literature. This improves bed use and hospital efficiency while maintaining a high degree of patient satisfaction. We conclude that with intensive patient care and education most patients undergoing laparoscopic pyeloplasty may be discharged home safely on postoperative day 1.     

Utilizing time-driven activity-based costing to determine open radical cystectomy and ileal conduit surgical episode cost drivers

ObjectivesPatients undergoing radical cystectomy represent a particularly resource-intensive patient population. Time-driven activity based costing (TDABC) assigns time to events and then costs are based on the people involved in providing care for specific events. To determine the major cost drivers of radical cystectomy care we used a TDABC analysis for the cystectomy care pathway.Subjects and methodsWe retrospectively reviewed a random sample of 100 patients out of 717 eligible patients undergoing open radical cystectomy and ileal conduit for bladder cancer at our institution between 2012 and 2015. We defined the cycle of care as beginning at the preoperative clinic visit and ending with the 90-day postoperative clinic visit. TDABC was carried out with construction of detailed process maps. Capacity cost rates were calculated and the care cycle was divided into 3 phases: surgical, inpatient, and readmissions. Costs were normalized to the lowest cost driver within the cohort.ResultsThe mean length of stay was 6.9 days. Total inpatient care was the main driver of cost for radical cystectomy making up 32% of the total costs. Inpatient costs were mainly driven by inpatient staff care (76%). Readmissions were responsible for 29% of costs. Surgery was 31% of the costs, with the majority derived from operating room staff costs (65%).ConclusionThe major driver of cost in a radical cystectomy pathway is the inpatient stay, closely followed by operating room costs. Surgical costs, inpatient care and readmissions all remain significant sources of expense for cystectomy and efforts to reduce cystectomy costs should be focused in these areas.     

High Bundled Payment Costs Following Total Hip and Knee Arthroplasty in African Americans

BackgroundConcerns exist that minorities who utilize more resources in an episode-of-care following total hip (THA) and knee arthroplasty (TKA) may face difficulties with access to quality arthroplasty care in bundled payment programs. The purpose of this study is to determine if African American patients undergoing TKA or THA have higher episode-of-care costs compared to Caucasian patients.MethodsWe queried Medicare claims data for a consecutive series of 7310 primary TKA and THA patients at our institution from 2015 to 2018. We compared patient demographics, comorbidities, readmissions, and 90-day episode-of-care costs between African American and Caucasian patients. A multivariate regression analysis was performed to identify the independent effect of race on episode-of-care costs.ResultsCompared to Caucasians, African Americans were younger, but had higher rates of pulmonary disease and diabetes. African American patients had increased rates of discharge to a rehabilitation facility (20% vs 13%, P < .001), with higher subacute rehabilitation ($1909 vs $1284, P < .001), home health ($819 vs $698, P = .022), post-acute care ($5656 vs $4961, P = .008), and overall 90-day episode-of-care costs ($19,457 vs $18,694, P = .001). When controlling for confounding comorbidities, African American race was associated with higher episode-of-care costs of $440 (P < .001).ConclusionAfrican American patients have increased episode-of-care costs following THA and TKA when compared to Caucasian patients, mainly due to increased rates of home health and rehabilitation utilization. Further study is needed to identify social variables that can help reduce post-acute care resources and prevent reduction in access to arthroplasty care in bundled payment models.     

Conversion Total Knee Arthroplasty: Prior Fracture or Osteotomy Around the Knee Leads to Increased Resource Utilization

BackgroundPrior knee surgery before total knee arthroplasty (TKA) puts patients at higher risk of inferior outcomes and increased care cost. This study compares intraoperative and postoperative variables including procedure duration, components, length of stay, readmission, complications, and reoperations among patients undergoing conversion TKA.MethodsPrimary TKA from a single-surgeon database identified 130 patients with prior knee surgery to form a “conversion” cohort. One-to-one matching identified 130 patients of similar age, American Society of Anesthesiologists score, body mass index, and gender without prior knee surgery for comparison. Perioperative and 90-day postoperative variables were compared between patients with and without prior surgery, within the conversion group based on the type of prior surgery, and whether the prior surgery was bony or soft tissue.ResultsThe conversion group had longer mean operative time (96.1 vs 90.0 minutes, P = .01), higher revision component utilization (8.5% vs 0.8%, P = .005), and higher calculated blood loss (1440 vs 1249 mL, P = .004). Thirty-eight patients with prior fracture or osteotomy were compared to the remaining 92 patients in the conversion group and showed longer operative time (107.1 vs 91.3 minutes, P < .001), higher 90-day readmissions (18.4% vs 3.3%, P = .003), more complications (23.7% vs 8.7%, P = .021), and greater utilization of revision components (26.3% vs 1.1%, P < .001).ConclusionPatients undergoing conversion TKA required increased resource utilization, particularly patients with a prior osteotomy or fracture. Policymakers should consider these variables, as they did in conversion THA, in adding a code to account for increased case complexity and resource utilization.     

The Hospital Frailty Risk Score is Not an Accurate Predictor of Treatment Costs for Total Joint Replacement Patients in a Medicare Bundled Payment Population

BackgroundMedically complex patients require more resources and experience higher costs within total joint arthroplasty (TJA) bundled payment models. While risk adjustment would be beneficial for such patients, no tool currently exists which can reliably identify these patients preoperatively. The purpose of this study is to determine if the Hospital Frailty Risk Score (HFRS) is a valid predictor of high-TJA treatment costs.MethodsRetrospective analysis was performed on patients who underwent primary TJA between 2015 and 2020 from a single large orthopedic practice. ICD-10 codes from an institutional database were used to calculate HFRS. Cost data including inpatient, postacute, and episode of care (EOC) costs were collected. Charlson comorbidity index, demographics, readmissions, and complications were analyzed.Results4936 patients had a calculable HFRS and those with intermediate and high scores experienced more frequent readmissions/complications after TJA, as well as higher EOC costs. However, HFRS did not reliably predict EOC costs, yielding a sensitivity of 49% and specificity of 66%. Multivariate analysis revealed that both patient age and sex are superior individual cost predictors when compared with HFRS. Secondary analyses indicated that HFRS more effectively predicts TJA complications and readmissions but is still nonideal for clinical applications.ConclusionHFRS has poor sensitivity as a predictor of high-EOC costs for TJA patients but has adequate specificity for predicting postoperative readmissions and complications. Further research is needed to develop a scale that can appropriately predict orthopedic cost outcomes.     

The use and modification of clinical pathways to achieve specific outcomes in bariatric surgery

Clinical pathways are promoted for standardizing patient care and decreasing resource use without compromising outcome. Once established, we hypothesized that clinical pathways can then be used to modify patient care to achieve specific goals. Our aim was to evaluate a clinical pathway for the bariatric surgical patient that was initially designed to standardize care and later altered to modify the postoperative course. We retrospectively reviewed 150 consecutive patients undergoing open gastric bypass by a single surgeon. The first 50 patients were managed without a formal pathway, (group I). The next 50 were managed with a pathway that standardized care in order to reduce length of stay (LOS), (group II). For the final 50 patients, the pathway was modified to shorten nasogastric decompression time (group III). Patient information, blood loss (EBL), operative time, length of stay (LOS), nasogastric decompression, 30-day complication rates, and early readmissions were reviewed. The groups were similar with respect to gender, age, body mass index, American Society of Anesthesiologists (ASA) classification, and EBL. Operative time was significantly less in groups II and III compared to group I (82% and 68% vs. 38% <180 minutes, P < 0.05). LOS was shorter in groups II and III compared to group I (62% and 42% vs. 20% with a 4-day LOS, P < 0.05). Duration of nasogastric tube decompression was successfully decreased in group III when compared to groups I and II (76% vs. 14% and 6% 1 day or less, P < 0.05). Complication rates were significantly lower in group III as well (14% vs. 36% and 28%, P < 0.05). Standardizing patient care with a clinical pathway decreases LOS after bariatric surgery. An established clinical pathway can then be used to further modify patient care in order to achieve specific goals, such as shortened time of nasogastric decompression. This goal was accomplished without compromising patient outcome.     

Luces y sombras de la duodenopancreatectomía cefálica laparoscópica

IntroductionLaparoscopic pancreaticoduodenectomy (PD) is not widely accepted, and its use is controversial. Only correct patient selection and appropriate training of groups experienced in pancreatic surgery and laparoscopy will be able to establish its role and its hypothetical advantagesMethodsOut of 138 pancreatic surgeries performed in a two-year period (2017-2019), 23 were laparoscopic PD. We evaluate its efficacy and safety compared to 31 open PD.ResultsThere were no cases of B/C pancreatic or biliary fistula, nor any cases of delayed gastric emptying in the laparoscopic group, but hemorrhage required one reoperation. The conversion rate was 21% (five cases): one due to bleeding, and the remainder for non-progression. The converted patients showed no differences compared to those completed by laparoscopy. There were no differences between laparoscopic and open PD in surgical time, postoperative complications, reintervention rate, readmissions or mortality. R0 resection in tumor cases was 85% for laparoscopy and 69% in open surgery without statistical significance. The postoperative hospital stay was shorter in the laparoscopic PD group (eight vs. 15 days).ConclusionsIn a selected group, laparoscopic PD can be safely and effectively performed if carried out by groups who are experts in pancreatic surgery and advanced laparoscopy. The technique has the same postoperative results as open surgery and is oncologically adequate, with less hospital stay. Proper patient selection, a step-by-step program and a lax and early conversion prevents serious operating accidents.     

Elective infrainguinal lower extremity bypass for claudication is associated with high postoperative intensive care utilization

BackgroundThe overall use of intensive care units (ICUs) in the United States has been steadily increasing and is associated with tremendous health care costs. We suspect that the burden of ICU utilization after elective infrainguinal lower extremity bypass (LEB) procedures is high, despite relatively low risks of complications in the immediate postoperative period. We sought to identify the burden of ICU utilization after elective LEB in patients with claudication.MethodsWe queried the Premier Healthcare Database for all adult patients undergoing first recorded elective infrainguinal LEB for claudication from 2009 to 2015. Baseline characteristics and ICU utilization on postoperative day 0 (POD 0) were identified for each patient using Premier room and board chargemaster codes. A bivariate logistic regression was performed and postestimation concordance statistics were calculated to identify predictors of postoperative ICU vs regular surgical floor admission immediately after surgery.ResultsThere were 6010 patients who met the selection criteria, of whom 2772 (46.1%) were admitted to the ICU and 3238 (53.9%) to the regular surgical floor on POD 0. Whereas patient-level factors were responsible for minor differences found in postoperative admission to the ICU after elective LEB, hospital characteristics made up the majority of variation in admission practices. Specifically, patients undergoing elective infrainguinal LEB in rural, nonteaching, small hospitals and those in certain geographic regions were more likely to be admitted to the ICU than to the floor (all, P < .001). Patient-level factors were poorly predictive of admission to the ICU immediately postoperatively, with C statistics ranging from 0.50 to 0.53. In contrast, hospital-level factors had higher C statistics ranging from 0.51 to 0.66, with geographic location being the strongest predictor of post-LEB ICU admission. There were no significant differences in the incidence of postoperative wound complications, major adverse limb events, major adverse cardiac events, or in-hospital mortality between groups (all, P ≥ .32). The median total hospital cost was $2340 higher for ICU compared with floor admission ($13,273 [interquartile range, $10,136-$17,883] vs $10,927 [interquartile range, $8342-$14,523]; P < .001).ConclusionsNearly half of patients are admitted to an ICU directly after elective infrainguinal LEB for claudication. This practice is associated with significantly higher hospital cost and is predominantly influenced by hospital-level rather than by patient-level factors. Perioperative morbidity and mortality were similar regardless of postoperative disposition. To minimize ICU utilization, postoperative care intensity should be determined by clinical severity of the patient rather than by hospital routine.
