The impact of value-driven outcomes initiative on endo-laparoscopic groin hernia repair.

PURPOSE: Value driven outcome (VDO) initiative is a value-based, patient-focused tool which utilizes a clinical outcome-based approach to optimize value of care based on clinically relevant quality indicators and costs required to achieve the care. In this study, we evaluate the impact of a VDO initiative on groin hernia repair, a commonly performed elective surgery in our hospital. METHODS: A VDO initiative was implemented in 2019 to encourage elective inguinal hernia repair to be performed at a day surgery setting. A comparison of outcomes was made between hernia surgeries performed in 2019 with those in 2020 and 2021. Pre-defined criteria were used to select patients that can be operated at a day surgery setting. Patients' expectations were addressed preoperatively about day surgery procedure and postoperative recovery. Day surgery bundles were used to standardize pre- and post-surgery protocols. Pain control was optimized using a specialized local anesthesia regime. RESULTS: A total of 263 laparoscopic hernia surgeries were performed between May 2019 and December 2021. After implementation of VDO initiative, the percentage of patients discharged within 24 h increased from 78% in year 2019 to 97% in year 2020 and 99% in year 2021. Conversion rate for day surgery to short stay decreased from 9% in year 2019 to 1% in year 2020 and 2% in year 2021. In 2019 to 2021, there were no 30-day readmission, no hernia recurrence in 90 days, no conversion to open surgery. CONCLUSION: VDO initiative is a promising tool to deliver better value-based care for patients undergoing endo-laparoscopic inguinal hernia repair.

Cost analysis of primary single-level lumbar discectomies using the Value Driven Outcomes database in a large academic center.

BACKGROUND CONTEXT: Improving value is an established point of emphasis to reduce the rapidly rising health care costs in the United States. Back pain is a major driver of costs with a substantial fraction caused by lumbar radiculopathy. The most common surgical treatment for lumbar radiculopathy is microdiscectomy. Research is sparse regarding variables driving cost in microdiscectomies and often limited by cost data derived from payer-based Medicare data. PURPOSE: To identify targets for cost reduction by determining variables associated with significant cost variation in microdiscectomies, using cost data derived from the Value Driven Outcomes tool and actual system costs. STUDY DESIGN: Single-center, retrospective study of prospectively collected registry data. PATIENT SAMPLE: Six hundred twenty-two patients identified by CPT code and manually screened for initial, unilateral, single-level lumbar discectomy performed between 2014 and 2018 at a single institution. OUTCOME MEASURES: Primary outcome measures include total direct cost, clinical length of stay, and OR minutes. Total Direct Cost was further differentiated into facility and nonfacility costs. METHODS: Univariate and multivariate generalized linear models (GLM) were used to identify variables associated with variation in primary outcome measures. Costs were normalized by mean cost for patients with normal body mass index (BMI) and a healthy American Society of Anesthesiologists (ASA) classification. Average marginal effects were reported as percentage of normalized costs. RESULTS: Advanced age, male gender, Hispanic, black, unemployment, obesity, higher ASA class, insurance status, and being retired were positively associated with costs in univariate analysis. Asian, Native American, outpatient procedures, and being a student were associated with decreases in costs. In multivariate analysis, we found that obesity led to higher average marginal total direct (9%), total facility (15%), and facility OR costs (22%), as well as 24 more OR minutes per surgery. While being overweight was not associated with greater total direct costs, it was associated with higher total facility (8%), and facility OR costs (12%), with 11 more OR minutes per surgery. Age was associated with a longer LOS but not with OR costs. As expected, outpatient surgical costs, LOS, and OR time were significantly lower than inpatient procedures. Severe systematic disease was associated with greater total and nonfacility costs. In addition, Medicare patients had higher facility costs (14%) compared to privately insured patients. CONCLUSIONS: Significant drivers of total direct cost in multivariate GLM analysis were obesity, severe systemic disease and inpatient surgery. Average LOS was increased due to age and inpatient status, conversely it was decreased by unemployment and retirement. Significant variables in OR time were male sex, Hispanic race and both obese and overweight BMIs.

Evaluation of factors driving cost variation for distal humerus open reduction internal fixation.

BACKGROUND: Distal humerus fracture open reduction and internal fixation (ORIF) represents a substantial cost burden to the health care system. The purpose of this study was to describe surgical encounter cost variation for distal humerus ORIF, and to determine demographic-, injury-, and treatment-specific factors that influence cost. METHODS: We retrospectively identified adult patients (≥18 years) treated for isolated distal humerus fractures between July 2014 and July 2019 at a single tertiary academic referral center. For each case, surgical encounter total direct costs (SETDCs) were obtained via our institution's information technology value tools, which prospectively record granular direct cost data for every health care encounter. Costs were converted to 2019 dollars using the personal consumption expenditure indices for health and summarized with descriptive statistics. Univariate and multivariate linear regression models were used to identify factors influencing SETDC. RESULTS: Surgical costs varied widely for the 47 included patients, with a standard deviation (SD) of 33% and interquartile range of 76%-124% relative to the mean SETDC. Implant and facility costs were responsible for 46.2% and 32.6% of the SETDC, respectively. Implant costs also varied considerably, with an SD of 21% and range from 13%-36% relative to the mean SETDC. Multivariate analysis demonstrated that SETDC increased 24% (P < .001) on performing an olecranon osteotomy, and by 15% for each additional 1 hour of surgical time (P < .001). These findings were independent of age, sex, body mass index, open fracture, need for an additional small plate construct as a reduction aid, and fracture pattern (all insignificant in the multivariate analysis, with P >.05 for each factor). CONCLUSION: Substantial variations in surgical encounter total direct costs for distal humerus ORIF exist, as do wide variations in associated implant costs that comprise nearly half of the entire surgical cost. Performing an olecranon osteotomy, and increased surgical time, significantly increased surgical costs. Although use of an olecranon osteotomy may not be a completely controllable factor as it is confounded by fracture severity and operative time, this may suggest that surgeons should try to use an olecranon osteotomy judiciously. Although complexity of the fracture pattern was statistically insignificant, it is confounded by the need for an olecranon osteotomy and increased surgical time and likely is a clinically relevant and nonmodifiable driver of surgical cost. These findings highlight opportunities to reduce cost variation, and potentially improve the value of care, for distal humerus ORIF patients.

Evaluation of factors influencing surgical treatment costs for distal biceps rupture.

BACKGROUND: Given the similar outcomes of various fixation constructs for single-incision distal biceps repair, a critical evaluation of the factors that drive the cost of the procedure is the key to optimizing treatment value. The purpose of this study was to quantify variation in costs for surgical treatment of complete distal biceps ruptures, as well as identify factors affecting costs. METHODS: We retrospectively identified adult patients consecutively treated surgically for complete distal biceps ruptures between July 2011 and January 2018 at a single academic medical center. Using our institution's information technology value tool, we recorded the surgical encounter total direct costs (SETDCs) for each patient. Univariate and multivariate gamma regression models were used to determine factors affecting SETDCs. RESULTS: Of 121 included patients, 102 (86%), 7 (6%), and 12 (10%) underwent primary repair, revision, and reconstruction. SETDCs varied widely, with a standard deviation of 40% and a range of 58% to 276% of the average SETDC. The main contributors to SETDCs were facility utilization costs (53%) and implant costs (29%). Implant costs also varied, with a standard deviation of 16%, ranging up to 121% of the mean SETDC. Multivariate analysis demonstrated that reconstructions were 72% more costly than primary repairs (P < .001). No significant cost differences were found between cortical button and dual-suture anchor fixation (P = .058). American Society of Anesthesiologists class, body mass index, revision surgery, time to surgery, location, administration of postoperative block, and surgeon performing the procedure did not significantly affect the SETDC. CONCLUSION: Surgical encounter and implant costs vary widely for distal biceps rupture treatment. However, no significant difference in SETDC was identified between repair with a cortical button vs. dual-suture anchor repair. The greater costs associated with reconstruction surgery should be taken into consideration.

Initial Treatment for Unruptured Intracranial Aneurysm and Its Follow-up: A Cost Analysis of Pipeline Flow Diverters versus Coiling.

Purpose Intracranial aneurysms are relatively common epidemiological problems for which the surveillance, treatment, and follow-up are costly. Although multiple studies have evaluated the treatment cost of aneurysms, the follow-up costs are often not examined. In our study, we analyzed how follow-up costs after treatment affected the overall cost of different endovascular techniques for treating aneurysms. Materials and methods An institutional database was used to evaluate the upfront and follow-up costs incurred by patients who underwent elective coiling or placement of a pipeline embolization device (PED) for the treatment of unruptured intracranial aneurysms from July 2011 to December 2017. Results A total of 114 patients (coiling, n = 37; PED, n = 77 ) were included in the study. There was no significant difference among patients in mean age [61.3 (±12.8 years) vs. 57.0 (±14.5 years); probability value (p) = 0.2], sex (male: 32.4% vs. 22.1%; p = 0.2), American Society of Anesthesiologists (ASA) grade (p = 0.5), discharge disposition (p = 0.1), mean length of stay [3.1 days (±5.5) vs. 2.4 days (±2.6); p = 0.2) or follow-up period [22.7 months (±18.5) vs. 18.6 months (±14.9); p = 0.2). There were no differences in costs during admission (p = 0.5) or in follow-up (p = 0.3) between coiling and PED treatments. Initial costs were predominantly related to supplies/implants (56.1% vs. 63.7%) for both treatments. Follow-up costs mostly comprised facility costs (68.2% vs. 67.5%), and there were no differences in costs of subgroups such as supplies/implants (10.5% vs. 9.4%), imaging (17.0% vs. 17.8%), or facilties between coiling and PED. Conclusion These results suggest that the upfront and follow-up costs are mostly similar for the treatment of intracranial aneurysms irrespective of whether the providers used coiling or PED endovascular techniques. Hence, we conclude that follow-up costs should not be a deciding factor when considering these treatments.

Effect of patient age on glioblastoma perioperative treatment costs: a value driven outcome database analysis.

INTRODUCTION: Identification of groups of patients or interventions with higher associated treatment costs may be beneficial in efforts to decrease the overall financial burden of glioblastoma (GBM) treatment. The authors' objective was to evaluate perioperative surgical treatment cost differences between elderly and nonelderly patients with GBM using the Value Driven Outcome (VDO) database. METHODS: The authors obtained data from a retrospective cohort of GBM patients treated surgically (resection or biopsy) at their institution from August 2011 to February 2018. Data were compiled using medical records and the VDO database. RESULTS: A total of 181 patients with GBM were included. Patients were grouped into age < 70 years at time of surgery (nonelderly; n = 121) and ≥ 70 years (elderly; n = 60). Costs were approximately 38% higher in the elderly group on average (each patient was mean 0.68% of total cohort cost vs. 0.49%, p = 0.044). Higher age significantly, but weakly, correlated with higher treatment cost on linear regression analysis (p = 0.007; R2 = 0.04). Length of stay was significantly associated with increased cost on linear regression (p < 0.001, R2 = 0.84) and was significantly longer in the elderly group (8.7 ± 11.3 vs. 5.2 ± 4.3 days, p = 0.025). The cost breakdown by facility, pharmacy, supply/implants, imaging, and laboratory costs was not significantly different between age groups. Elderly patients with any postoperative complication had 2.1 times greater total costs than those without complication (p = 0.094), 2.9 times greater total costs than nonelderly patients with complication (p = 0.013), and 2.3 times greater total costs than nonelderly patients without complication (p = 0.022). CONCLUSIONS: GBM surgical treatment costs are higher in older patients, particularly those who experience postoperative complications.

Evaluation of cost and survival in intracranial gliomas using the Value Driven Outcomes database: a retrospective cohort analysis.

OBJECTIVE: Gliomas occur in 3-4 individuals per 100,000 individuals and are one of the most common primary brain tumors. Treatment options are limited for gliomas despite the progressive nature of the disease. The authors used the Value Driven Outcomes (VDO) database to identify cost drivers and subgroups that are involved in the surgical treatment of gliomas. METHODS: A retrospective cohort of patients with gliomas treated at the authors' institution from August 2011 to February 2018 was evaluated using medical records and the VDO database. RESULTS: A total of 263 patients with intracranial gliomas met the authors' inclusion criteria and were included in the analysis (WHO grade I: 2.0%; grade II: 18.5%; grade III: 18.1%; and grade IV: 61.4%). Facility costs were the major (64.4%) cost driver followed by supplies (16.2%), pharmacy (10.1%), imaging (4.5%), and laboratory (4.7%). Univariate analysis of cost contributors demonstrated that American Society of Anesthesiologists physical status (p = 0.002), tumor recurrence (p = 0.06), Karnofsky Performance Scale score (p = 0.002), length of stay (LOS) (p = 0.0001), and maximal tumor size (p = 0.03) contributed significantly to the total costs. However, on multivariate analysis, only LOS (p = 0.0001) contributed significantly to total costs. More extensive tumor resection in WHO grade III and IV tumors was associated with significant improvement in survival (p = 0.004 and p = 0.02, respectively). CONCLUSIONS: Understanding care costs is challenging because of the highly complex, fragmented, and variable nature of healthcare delivery. Adopting effective strategies that would reduce facility costs and limit LOS is likely the most important aspect in reducing intracranial glioma treatment costs.

Assessment of costs in open surgery and stereotactic radiosurgery for vestibular schwannomas.

OBJECTIVE: Microsurgical resection and radiosurgery remain the most widely used interventions in the treatment of vestibular schwannomas. There is a growing demand for cost-effectiveness analyses to evaluate these two treatment modalities and delineate the factors that drive their total costs. Here, the authors evaluated specific cost drivers for microsurgical and radiosurgical management of vestibular schwannoma by using the Value Driven Outcomes system available at the University of Utah. METHODS: The authors retrospectively reviewed all cases involving microsurgical and radiosurgical treatment of vestibular schwannomas at their institution between November 2011 and September 2017. Patient and tumor characteristics, subcategory costs, and potential cost drivers were analyzed. RESULTS: The authors identified 163 vestibular schwannoma cases, including 116 managed microsurgically and 47 addressed with stereotactic radiosurgery (SRS). There were significant differences between the two groups in age, tumor size, and preoperative Koos grade (p < 0.05), suggesting that indications for treatment were markedly different. Length of stay (LOS) and length of follow-up were also significantly different. Facility costs were the most significant contributor to both microsurgical and SRS groups (58.3% and 99.4%, respectively); however, physician professional fees were not specifically analyzed. As expected, microsurgical treatment resulted in an average 4-fold greater overall cost of treatment than for SRS cases (p < 0.05), and there was a greater variation in costs for open cases as well. Costs remained stable over time for both open resection and SRS. Multivariable analysis showed that LOS (ß = 0.7, p = 0.0001), discharge disposition (ß = 0.2, p = 0.004), nonserviceable hearing (ß = 0.1, p = 0.02), and complications (ß = 0.2, p = 0.005) affected cost for open surgery, whereas no specifically examined factor could be identified as driving costs for SRS. CONCLUSIONS: This analysis identified the fact that facility utilization constitutes the majority of total costs for both microsurgery and SRS treatment modalities of vestibular schwannomas. LOS, discharge disposition, nonserviceable hearing, and complications contributed significantly to the total costs for the microsurgical group, whereas none of the factors could be identified as driving total costs for the SRS group. This information may be used to establish policies and protocols to reduce facility costs, with the goal of decreasing the total costs without jeopardizing patient care.

Analysis of an overlapping surgery policy change on costs in a high-volume neurosurgical department.

OBJECTIVE: Overlapping surgery remains a controversial topic in the medical community. Although numerous studies have examined the safety profile of overlapping operations, there are few data on its financial impact. The authors assessed direct hospital costs associated with neurosurgical operations during periods before and after a more stringent overlapping surgery policy was implemented. METHODS: The authors retrospectively reviewed the records of nonemergency neurosurgical operations that took place during the periods from June 1, 2014, to October 31, 2014 (pre-policy change), and from June 1, 2016, to October 31, 2016 (post-policy change), by any of the 4 senior neurosurgeons authorized to perform overlapping cases during both periods. Cost data as well as demographic, surgical, and hospitalization-related variables were obtained from an institutional tool, the Value-Driven Outcomes database. RESULTS: A total of 625 hospitalizations met inclusion criteria for cost analysis; of these, 362 occurred prior to the policy change and 263 occurred after the change. All costs were reported as a proportion of the average total hospitalization cost for the entire cohort. There was no significant difference in mean total hospital costs between the prechange and postchange period (0.994 ± 1.237 vs 1.009 ± 0.994, p = 0.873). On multivariate linear regression analysis, neither the policy change (p = 0.582) nor the use of overlapping surgery (p = 0.273) was significantly associated with higher total hospital costs. CONCLUSIONS: A more restrictive overlapping surgery policy was not associated with a reduction in the direct costs of hospitalization for neurosurgical procedures.

Assessment of Costs in Open Microsurgery and Stereotactic Radiosurgery for Intracranial Meningiomas.

OBJECTIVE: Understanding costs of microsurgical or radiosurgical treatment of intracranial meningioma may offer direction in reducing health care costs and establishing cost-effective algorithms. We used the Value Driven Outcomes database, which identifies cost drivers and tracks changes over time, to evaluate cost drivers for management of intracranial meningioma. METHODS: A single-center, retrospective cohort of patients undergoing microsurgery or radiosurgery of intracranial meningiomas from July 2011 to April 2017 was analyzed. Patient and tumor characteristics, subcategory costs, and potential cost drivers were analyzed within each treatment modality. RESULTS: Of 268 intracranial meningiomas, 198 were treated with microsurgery and 70 with stereotactic radiosurgery. Facility costs were the largest contributor to total costs for microsurgery (59.7%), whereas imaging costs were the largest contributor to stereotactic radiosurgery total costs (98.2%). Patients with non-skull base tumors had larger tumors (3.7 ± 1.9 cm vs. 2.7 ± 1.2 cm, P = 0.0001) and were more likely to undergo microsurgery (81.7% vs. 55.2%) than patients with skull base tumors. Univariate analysis suggested that American Society of Anesthesiologists status, length of stay, discharge disposition, and maximal tumor size impacted cost during microsurgery (P = 0.001), but only length of stay (P = 0.0001) and maximal tumor size (P = 0.01) were drivers of total costs on multivariate analysis. For radiosurgery, age significantly affected cost on univariate (P = 0.001) and multivariate (P = 0.003) analysis. CONCLUSIONS: Implementing protocols to reduce facility usage and imaging would mitigate total costs and improve resource utilization while maintaining high-quality patient care. Additional cost-effectiveness studies evaluating patients with true therapeutic equipoise will provide further guidance in these efforts.

Patient- and Procedure-Specific Variables Driving Total Direct Costs of Outpatient Anterior Cruciate Ligament Reconstruction.

BACKGROUND: Few studies have investigated the influence of patient-specific variables or procedure-specific factors on the overall cost of anterior cruciate ligament reconstruction (ACLR) in an ambulatory surgery setting. PURPOSE: To determine patient- and procedure-specific factors influencing the overall direct cost of outpatient arthroscopic ACLR utilizing a unique value-driven outcomes (VDO) tool. STUDY DESIGN: Cohort study (economic and decision analysis); Level of evidence, 3. METHODS: All ACLRs performed by 4 surgeons over 2 years were retrospectively reviewed. Cost data were derived from the VDO tool. Patient-specific variables included age, body mass index, comorbidities, American Society of Anesthesiologists (ASA) classification, smoking status, preoperative Patient-Reported Outcomes Measurement Information System (PROMIS) Physical Function Computerized Adaptive Testing (PF-CAT) score, and preoperative Single Assessment Numeric Evaluation (SANE) score. Procedure-specific variables included graft type, revision status, associated injuries and procedures, time from injury to ACLR, surgeon, and operating room (OR) time. Multivariate analysis determined patient- and procedure-related predictors of total direct costs. RESULTS: There were 293 autograft reconstructions, 110 allograft reconstructions, and 31 hybrid reconstructions analyzed. Patient-specific factors did not significantly influence the ACLR cost. The mean OR time was shorter for allograft reconstruction (P < .001). Predictors of an increased direct cost included the use of an allograft or hybrid graft (44.5% and 33.1% increase, respectively; P < .001), increased OR time (0.3% increase per minute; P < .001), surgeon 3 or 4 (9.1% or 5.9% increase, respectively; P < .001 or P = .001, respectively), and concomitant meniscus repair (24.4% increase; P < .001). Within the meniscus repair cohort, all-inside, root, and combined repairs correlated with a 15.5%, 31.4%, and 53.2% increased mean direct cost, respectively, compared with inside-out repairs (P < .001). CONCLUSION: This study failed to identify modifiable patient-specific factors influencing direct costs of ACLR. Allografts and hybrid grafts were associated with an increased total direct cost. Meniscus repair independently predicted an increased direct cost, with all-inside, root, and combined repairs being costlier than inside-out repairs. The time-saving potential of all-inside meniscus repair was not realized in this study, making implant use a significant factor in the overall cost of ACLR with meniscus repair.

Value-driven cardiac surgery: Achieving "perfect care" after coronary artery bypass grafting.

OBJECTIVE: The objective of this study was to determine if the implementation of a value-driven outcomes tool comprising modifiable quality and utilization metrics lowers cost and improves value of coronary artery bypass grafting (CABG) postoperative care. METHODS: Ten metrics were defined for CABG patients in 2 temporally separated phases. Clinical care protocols were designed and implemented to increase compliance with these metrics. Clinical outcomes and cost data were harvested from the electronic medical record using a proprietary value-driven outcomes tool and verified by a data management team. "Perfect care" was defined as achieving all 10 metrics per patient episode. RESULTS: Over a 45-month period, data of 467 consecutive patients who underwent isolated CABG were analyzed. "Perfect care" was successfully achieved in 304 patients (65.1%). There were no observed differences in mortality between patient groups. Linear regression analysis showed a negative correlation between percent compliance with "perfect care" and mean cost. When multivariate analysis was used to adjust for preoperative risk score, mean cost for patients with "perfect care" was 37.0% less than for those without "perfect care." CONCLUSIONS: In the context of focused institution-specific interventions to target quality and utilization metrics for CABG care, clinical care pathways and protocols informed by innovative tools that link automated tracking of these metrics to cost data might simultaneously promote quality and decrease costs, thereby enhancing value. This descriptive study provides preliminary support for a systematic approach to define, measure, and modulate the drivers of value for cardiothoracic surgery patients.

Assessment of cost drivers and cost variation for lumbar interbody fusion procedures using the Value Driven Outcomes database.

OBJECTIVE Efforts to examine the value of care-combining both costs and quality-are gaining importance in the current health care climate. This thrust is particularly evident in treating common spinal disease where both incidences and costs are generally high and practice patterns are variable. It is often challenging to obtain direct surgical costs for these analyses, which hinders the understanding of cost drivers and cost variation. Using a novel tool, the authors sought to understand the costs of posterior lumbar arthrodesis with interbody devices. METHODS The Value Driven Outcomes (VDO) database at the University of Utah was used to evaluate the care of patients who underwent open or minimally invasive surgery (MIS), 1- and 2-level lumbar spine fusion (Current Procedural Terminology code 22263). Patients treated from January 2012 through June 2017 were included. RESULTS A total of 276 patients (mean age 58.9 ± 12.4 years) were identified; 46.7% of patients were men. Most patients (82.2%) underwent 1-level fusion. Thirteen patients (4.7%) had major complications and 11 (4.1%) had minor complications. MIS (ß = 0.16, p = 0.002), length of stay (ß = 0.47, p = 0.0001), and number of operated levels (ß = 0.37, p = 0.0001) predicted costs in a multivariable analysis. Supplies and implants (55%) and facility cost (36%) accounted for most of the expenditure. Other costs included pharmacy (7%), laboratory (1%), and imaging (1%). CONCLUSIONS These results provide direct cost accounting for lumbar fusion procedures using the VDO database. Efforts to improve the value of lumbar surgery should focus on high cost areas, i.e., facility and supplies/implant.

Analysis of cerebrovascular aneurysm treatment cost: retrospective cohort comparison of clipping, coiling, and flow diversion.

OBJECTIVE With the continuous rise of health care costs, hospitals and health care providers must find ways to reduce costs while maintaining high-quality care. Comparing surgical and endovascular treatment of intracranial aneurysms may offer direction in reducing health care costs. The Value-Driven Outcomes (VDO) database at the University of Utah identifies cost drivers and tracks changes over time. In this study, the authors evaluate specific cost drivers for surgical clipping and endovascular management (i.e., coil embolization and flow diversion) of both ruptured and unruptured intracranial aneurysms using the VDO system. METHODS The authors retrospectively reviewed surgical and endovascular treatment of ruptured and unruptured intracranial aneurysms from July 2011 to January 2017. Total cost (as a percentage of each patient's cost to the system), subcategory costs, and potential cost drivers were evaluated and analyzed. RESULTS A total of 514 aneurysms in 469 patients were treated; 273 aneurysms were surgically clipped, 102 were repaired with coiling, and 139 were addressed with flow diverter placements. Middle cerebral artery aneurysms accounted for the largest portion of cases in the clipping group (29.7%), whereas anterior communicating artery aneurysms were most frequently involved in the coiling group (30.4%) and internal carotid artery aneurysms were the majority in the flow diverter group (63.3%). Coiling (mean total cost 0.25% ± 0.20%) had a higher cost than flow diversion (mean 0.20% ± 0.16%) and clipping (mean 0.17 ± 0.14%; p = 0.0001, 1-way ANOVA). Coiling cases cost 1.5 times as much as clipping and flow diversion costs 1.2 times as much as clipping. Facility costs were the most significant contributor to intracranial clipping costs (60.2%), followed by supplies (18.3%). Supplies were the greatest cost contributor to coiling costs (43.2%), followed by facility (40.0%); similarly, supplies were the greatest portion of costs in flow diversion (57.5%), followed by facility (28.5%). Cost differences for aneurysm location, rupture status, American Society of Anesthesiologists (ASA) grade, and discharge disposition could be identified, with variability depending on surgical procedure. A multivariate analysis showed that rupture status, surgical procedure type, ASA status, discharge disposition, and year of surgery all significantly affected cost (p < 0.0001). CONCLUSIONS Facility utilization and supplies constitute the majority of total costs in aneurysm treatment strategies, but significant variation exists depending on surgical approach, rupture status, and patient discharge disposition. Developing and implementing approaches and protocols to improve resource utilization are important in reducing costs while maintaining high-quality patient care.

Improving value in primary total joint arthroplasty care pathways: changes in inpatient physical therapy staffing.

BACKGROUND: An early physical therapy (PT) care pathway was implemented to provide same-day ambulation after total joint arthroplasty by changing PT staffing hours. METHODS: After receiving an exemption from our institutional review board, we performed a secondary data analysis on a cohort of patients that underwent primary TJA of the hip or knee 6 months before and 12 months after implementation of the change. Data on same-day ambulation rates, length of stay (LOS), and in-hospital costs were reviewed. RESULTS: Early evaluation and mobilization of patients by PT improved on postoperative day (POD) 0 from 64% to 85% after the change (P ≤ .001). The median LOS before the change was 3.27 days compared to 3.23 days after the change (P = .014). Patients with higher American Society of Anesthesiologists scores were less likely to ambulate on POD 0 (P = .038) and had longer hospital stays (P < .001). Early mobilization in the entire cohort was associated with a greater cost savings (P < .001). CONCLUSIONS: A relatively simple change to staffing hours, using resources currently available to us, and little additional financial or institutional investment resulted in a significant improvement in the number of patients ambulating on POD 0, with a modest reduction in both LOS and inpatient costs.
