Abstract:

Purpose: total joint replacement is one of the most successful procedures in medicine and cost reimbursements to hospitals for the joint arthroplasty diagnosisrelated group are among the largest payments made by a Regional Health Service. Despite the popularity of these procedures, there are few high-quality costeffectiveness studies on this topic. This study evaluates the cost of total joint arthroplasty performed in a district hospital. Methods: direct and indirect costs have been measured and patient procedure pathway was analyzed subdivided into three stages: surgical procedure, inpatient care and outpatient clinic. Results: the cost of the surgical procedure stage was calculated as 3,798 euros, while that of the inpatient stage was 2,924 euros. The mean hospital costs per procedure amounted to 6,952 euros. Conclusions: although the Health Service tariffs fully reimburse the cost of providing a joint replacement, our data contribute to point out the role of hospital staff ’s organization to support sustainable improvements on health care for joint replacement surgery. Level of evidence: Level VI, single economic evaluation.

Abstract:

Background and Objectives: Academic medical centers (AMC) are among some of the most expensive places to provide care. One way to cut costs is by decreasing unnecessary referrals to specialists for procedures that can be provided by well-trained primary care physicians. Our goal is to measure the financial impact of an office-based minor procedure service driven entirely by family physicians. Methods: We examined claims data for procedures performed on patients insured under our AMC’s home-grown accountable care organization-style health plan (Stanford Health Care Alliance [SHCA]). Descriptive statistics was used to compare the volume and cost of procedures performed by family medicine (FM) versus specialty care (SC). We preformed a subanalysis of SC procedures to explore the degree to which consultation and facility fees increased costs for SC. We used mathematical modeling to estimate the impact on cost of care if procedures were shifted from SC to FM and to calculate a return on investment (ROI). Results: Our data set examined 6,974 outpatient procedures performed on SHCA patients from 2016-2018 at a cost of $5,263,720 to SHCA. FM performed 6% of procedures at an average cost of $236 per procedure, while SC performed 94% of procedures at an average cost of $787 per procedure. FM saved money for all 12 types of skin, musculoskeletal, and reproductive procedures assessed; the average saved per procedure was $551. This represents a 70% cost savings. ROI was 2.33; for every $1 spent on FM procedures, SHCA saved $2.33. Conclusion: A family medicine minor procedure service significantly lowered health spending at our AMC.

Abstract:

This study explored radiology procedure cost across available units in the Radiology’s Department UKMMC (University Kebangsaan Malaysia Medical Centre). In 2011, the total number of radiology procedures carried out in this department was 121,221. Nevertheless, the estimating expenses of offering these procedures are not known. An economic evaluation study was employed and cost centric data mining based on costing activity method was used to determine the charge of the procedure in every centre. Information on seven cost parameters was collected for each procedure: human resources, consumables, equipment, reagents, administration, maintenance and utilities. The results of the study show that the highest percentage of cost parameter for the human resource was Radiology (Mobile) 57.5%, the highest percentage of cost parameter for consumables and reagent was EIR (Endovascular International Radiology) Unit 75.8% and Medical Nuclear Unit 68.1% was the highest percentage of cost parameter for reagent. The MRI (Magnetic Resonance Imaging) Unit 81.4% was the highest cost parameter for equipment. The most top mean cost procedures were EIR MYR4330 and it was revealed that procedures with the highest difference ratio were procedures in EIR (18.50). Finding of this study is very useful to UKMMC management since it helps to enhance the efficiency of services and reduce unnecessary radiology procedures in patient’s management.

Abstract:

ABSTRACT Objective: To measure the average direct cost of peripherally inserted central catheterization performed by nurses in a pediatric and neonatal intensive care unit. Method: A quantitative, exploratory-descriptive, single-case study, whose sample consisted of the non-participant observation of 101 peripherally inserted central catheter procedures. The cost was calculated by multiplying the execution time (timed using a chronometer) spent by nursing professionals, participants in the procedure, by the unit cost of direct labor, added to the cost of materials, drugs, and solutions. Results: The average direct cost of the procedure was US$ 326.95 (standard deviation = US$ 84.47), ranging from US$ 99.03 to US$ 530.71, with a median of US$ 326.17. It was impacted by material costs and the direct labor of the nurses. Conclusion: The measurement of the average direct cost of the peripherally inserted central catheter procedure shed light on the financials of consumed resources, indicating possibilities of intervention aiming to increase efficiency in allocating these resources.

Abstract:

Benefit/cost analysis is a technique for evaluating programs, procedures, and actions; it is not a moral theory. There is significant controversy over the moral justification of benefit/cost analysis. When a procedure for evaluating social policy is challenged on moral grounds, defenders frequently seek a justification by construing the procedure as the practical embodiment of a correct moral theory. This has the apparent advantage of avoiding difficult empirical questions concerning such matters as the consequences of using the procedure. So, for example, defenders of benefit/cost analysis (BCA) are frequently tempted to argue that this procedure just is the calculation of moral Tightness – perhaps that what it means for an action to be morally right is just for it to have the best benefit-to-cost ratio given the accounts of “benefit” and “cost” that BCA employs. They suggest, in defense of BCA, that they have found the moral calculus – Bentham's “unabashed arithmetic of morals.” To defend BCA in this manner is to commit oneself to one member of a family of moral theories (let us call them benefit/cost moral theories or B/C moral theories) and, also, to the view that if a procedure is (so to speak) the direct implementation of a correct moral theory, then it is a justified procedure. Neither of these commitments is desirable, and so the temptation to justify BCA by direct appeal to a B/C moral theory should be resisted; it constitutes an unwarranted short cut to moral foundations – in this case, an unsound foundation. Critics of BCA are quick to point out the flaws of B/C moral theories, and to conclude that these undermine the justification of BCA. But the failure to justify BCA by a direct appeal to B/C moral theory does not show that the technique is unjustified. There is hope for BCA, even if it does not lie with B/C moral theory.

Abstract:

Abstract The purpose of this paper is to show by multivariate regression model if a defective procurement procedure leading to a contract award affects the smooth execution of a project in terms of its cost performance on the strength of the significance of the model. This investigation was conducted with a quantitative method of research by administering questionnaires to key industry players (clients, consultants, and contractors) engaged in construction projects (both civil and building works) in assessing contract award procedures, conditions for contract award after tender evaluation and criteria for contractors’ prequalification. Data from their field survey was analysed with mean item score to show hierarchal importance of factors and critical evaluation using multivariate analysis of variance. Findings showed that a poor and inappropriate contract award procedure has divergence from efficient project cost management based on the corollary of mean score values of contract award procedures, conditions for the award and prequalification test. The practical implication of this, is that an unbiased contract award procedure will apparently lead to a lesser strenuous project management effort towards mitigating cost spills and overruns for a lesser project abandonment if the right contractor with the right capabilities is awarded the contract. These implications stem from the originality of the investigation arising from F-value statistics (7.406), t-value statistics (3.046), and p-value of 0.003.

Abstract:

OBJECTIVE: To evaluate the yield and cost effectiveness of transbronchial needle aspiration (TBNA) in the assessment of mediastinal and/or hilar lymphadenopathy.DESIGN: Retrospective study.SETTING: A university hospital.POPULATION STUDIED: Ninety-six patients referred for bronchoscopy with computed tomographic evidence of significant mediastinal or hilar adenopathy.RESULTS: Ninety-nine patient records were reviewed. Three patients had two separate bronchoscopy procedures. TBNA was positive in 42 patients (44%) and negative in 54 patients. Of the 42 patients with a positive aspirate, 40 had malignant cytology and two had cells consistent with benign disease. The positive TBNA result altered management in 22 of 40 patients with malignant disease and one of two patients with benign disease, thereby avoiding further diagnostic procedures. The cost of these subsequent procedures was estimated at $27,335. No complications related to TBNA were documented.CONCLUSIONS: TBNA is a high-yield, safe and cost effective procedure for the diagnosis and staging of bronchogenic cancer.

Abstract:

We conducted a study to analyze hospital and patient costs, outcomes, and patient satisfaction among adults undergoing in-office and operating room procedures for the treatment of recurrent respiratory papillomatosis. Our final study population was made up of 17 patients—1 man and 16 women, aged 30 to 86 years (mean: 62). The mean number of in-office laser procedures per patient was 4.2, and the mean interval between procedures was 5.4 months (although 10 patients underwent only 1 office procedure); the mean number of operating room procedures was 13.5, and the mean interval between procedures was 14.3 months. An equal number of patients reported complications or adverse events with the two types of procedures—5 each. The difference in cost between the office procedure (mean: $3,413.00) and the operating room procedure (mean: $12,382.59) was almost $9,000, but these savings were offset by the fact that the office procedures needed to be performed three times as often. Patients reported slightly more anxiety and discomfort during the office procedures and, overall, they appeared to prefer the operating room procedure. We conclude that office procedures are significantly more cost-effective than operating room procedures, but their use may be limited by patient tolerance and the increased frequency of the procedure.

Abstract:

OBJECT The objective of this study was to compare the cost of deep brain stimulation (DBS) performed awake versus asleep at a single US academic health center and to compare costs across the University HealthSystem Consortium (UHC) Clinical Database. METHODS Inpatient and outpatient demographic and hospital financial data for patients receiving a neurostimulator lead implant (from the first quarter of 2009 to the second quarter of 2014) were collected and analyzed. Inpatient charges included those associated with International Classification of Diseases, Ninth Revision (ICD-9) procedure code 0293 (implantation or replacement of intracranial neurostimulator lead). Outpatient charges included all preoperative charges ≤ 30 days prior to implant and all postoperative charges ≤ 30 days after implant. The cost of care based on reported charges and a cost-to-charge ratio was estimated. The UHC database was queried (January 2011 to March 2014) with the same ICD-9 code. Procedure cost data across like hospitals (27 UHC hospitals) conducting similar DBS procedures were compared. RESULTS Two hundred eleven DBS procedures (53 awake and 158 asleep) were performed at a single US academic health center during the study period. The average patient age ( ± SD) was 65 ± 9 years old and 39% of patients were female. The most common primary diagnosis was Parkinson’s disease (61.1%) followed by essential and other forms of tremor (36%). Overall average DBS procedure cost was $39,152 ± $5340. Asleep DBS cost $38,850 ± $4830, which was not significantly different than the awake DBS cost of $40,052 ± $6604. The standard deviation for asleep DBS was significantly lower (p ≤ 0.05). In 2013, the median cost for a neurostimulator implant lead was $34,052 at UHC-affiliated hospitals that performed at least 5 procedures a year. At Oregon Health & Science University, the median cost was $17,150 and the observed single academic health center cost for a neurostimulator lead implant was less than the expected cost (ratio 0.97). CONCLUSIONS In this single academic medical center cost analysis, DBS performed asleep was associated with a lower cost variation relative to the awake procedure. Furthermore, costs compared favorably to UHC-affiliated hospitals. While asleep DBS is not yet standard practice, this center exclusively performs asleep DBS at a lower cost than comparable institutions.

Abstract:

This study was conducted in order to evaluate the cost-effectiveness of percutaneous automated lumbar nucleotomy in comparison with traditional macro-procedure discectomy in the treatment of herniated discs. Sixty-eight patients undergoing surgical procedures and 90 treated with nucleotomy were consecutively included. Both cohorts were assessed pre-operatively and at regular intervals for one year or more after treatment by independent observers, using a clinical overall scoring system (COS) with 0 being the best attainable result and 1000 the poorest conceivable status of the patients. There were better clinical results after surgery with 78% successes after one year compared to 62% after nucleotomy. By including subsequent operations and re-operations after failure to respond to the primary treatment, the success rates rose to 79% and 77%, respectively. The cost of surgical treatment was calculated to USD 6.119 per patient and the cost of a nucleotomy procedure was USD 1.252. Owing to an almost five times higher price of surgery than nucleotomy, the latter turned out to be 2.7 to 3.9 times more cost-effective, depending on whether secondary treatment was included or not. Due to the minimal difference in final outcome between the groups, however, the marginal cost per extra success in patients primarily treated with surgery was as high as USD 205.850. The study concludes that nucleotomy, as a mini-invasive procedure with low complication rates and the potential of a quick recovery, is more cost-effective than traditional surgical treatment for lumbar disc herniation.

Full text

Abstract:

We study a setting in which a firm faces commercial and cost-reimbursed products, and, following Rogerson (1992), examine the factor choice distortions that are induced by the cost-based reimbursement arrangement. The firm's technology is separable, which allows us to rationalize fully an ABC procedure (given constant returns to scale) and also allows us to document whether the distortions occur in the direct or indirect subcost functions. The location and magnitude of the distortions depend on the precise costing procedure, but the preference for an ABC versus traditional procedure is far more subtle. Absent constant returns, any (linear) accounting procedure invites factor distortions because of the cost-reimbursement feedback, but the economic impact of these distortions depends on the technology, the relative prices, and the costing procedure.

Abstract:

Objectives: Percutaneous core-needle biopsy (PCNB) is the standard of care to biopsy and diagnose suspicious breast lesions. Dependent on histology, many patients require additional open procedures for definitive diagnosis and excision. This study estimated the payer and patient out-of-pocket (OOP) costs, and complication risk, among those requiring at least 1 open procedure following PCNB. Methods: This retrospective study used the Truven Commercial database (2009-2014). Women who underwent PCNB, with continuous insurance, and no history of cancer, chemotherapy, radiation, or breast surgery in the prior year were included. Open procedures were defined as open biopsy or lumpectomy. Study follow-up ended at chemotherapy, radiation, mastectomy, or 90 days—whichever occurred first. Results: In total, 143 771 patients (mean age 48) met selection criteria; 85.1% underwent isolated PCNB, 12.4% one open procedure, and 2.5% re-excision. Incidence of complications was significantly lower among those with PCNB alone (9.2%) vs 1 open procedure (15.6%) or re-excision (25.3%, P < .001). Mean incremental commercial payments were US $13 190 greater among patients with 1 open procedure vs PCNB alone (US $17 125 vs US $3935, P < .001), and US $4767 greater with re-excision (US $21 892) relative to 1 procedure. Mean patient OOP cost was US $858 greater for 1 open procedure vs PCNB alone (US $1527 vs US $669), and US $247 greater for re-excision vs 1 procedure. Conclusions: A meaningful proportion of patients underwent open procedure(s) following PCNB which was associated with increased complication risk and costs to both the payer and the patient. These results suggest a need for technologies to reduce the proportion of cases requiring open surgery and, in some cases, re-excision.

Full text

Abstract:

Sufficient safety of welded structures against fatigue damage is achieved through the use of several safety procedures, design of the structure, quality control of the welding procedure during fabrication, and inspection for fatigue cracks with subsequent repair of detected cracks. Each safety procedure has a certain cost, and it is important to minimize the total expected cost over the lifetime of the structure. The present paper presents a probability-based optimization procedure defining optimal initial design, quality of welding procedure at fabrication, time of inspections, quality of inspections, and length of weld to be inspected at each inspection for a continuous weld. The cost considered in the optimization is cost-related to initial design, cost of fabrication, cost of inspection, expected repair cost, and expected failure cost. The probabilistic optimization problem is formulated for a homogeneous continuously welded structure containing hazardous material for which no leakage is permissible. The weld seam considered has multiple potential crack initiation sites from weld defects, where all the crack initiation sites are exposed to the same stochastic loading condition. Two models are applied to define the distribution of weld defects over the weld seam: a model where the locations of the crack initiation sites are known, and a model where the locations and number of crack initiation sites are unknown and described through a homogeneous Poisson distribution process. Uncertainties in the long-term stochastic load process, the fatigue strength, and the crack size of the different initial defects are considered in the procedure.

Abstract:

BackgroundEndovascular treatment of aneurysms with coils is among the most frequent treatments in interventional neuroradiology, and represents an important expense. Each manufacturer has created several types of coils, with prices varying among brands and coil types. The objective of this study was to assess the impact of cost awareness of the exact price of each coil by the operating physician on the total cost of aneurysm coiling.Materials and methodsThis was a comparative study conducted over 1 year in a single tertiary care center. The reference cohort and the experimental cohort consisted of all aneurysm embolization procedures performed during the first 6 months and the last 6 months, respectively. During the second period, physicians were given an information sheet with the prices of all available coils and were requested to look at the sheet during each procedure with the instruction to try to reduce the total cost of the coils used. Expenses related to the coiling procedures during each period were compared.Results77 aneurysms (39 ruptured) in the reference cohort and 73 aneurysms (36 ruptured) in the experimental cohort were treated, respectively. There was no statistically significant difference regarding aneurysm location and mean size. The overall cost of the coiling procedures, the mean number of coils used per procedure, and the median cost of each procedure did not differ significantly between the two cohorts.ConclusionAwareness of the precise price of coils by operators without any additional measure did not have a scientifically proven impact on the cost of aneurysm embolization.

Abstract:

Purpose: To analyze the cost structure of procedures performed in a multipurpose interventional magnetic resonance imaging (IMRI) unit and to analyze the effect of procedure shares on cost structure. Material and Methods: During a 1-year period, 691 procedures were performed in the IMRI unit, of which 563 were diagnostic MRI examinations, 89 MRI-guided interventions, and 39 MRI-guided neurosurgical operations. Three alternative utilization models of IMRI were created to simulate different local institutions by adjusting the proportions of different procedures. The costs of procedures were calculated by activity-based cost analysis. Results: The cost of the main procedure (imaging, biopsy, injection, or operation) was the most significant item in all procedures, accounting for 66–89% of the total costs. The volume of imaging has a major effect on unit costs. Volume is not such a deterministic factor in interventions due to the high material costs. The volume of neurosurgical use of IMRI has a major effect on the costs of radiological procedures due to the long operation times. Conclusion: The volumes of different procedures done on an IMRI unit have significant effects on the unit costs of the procedures.

Abstract:

AbstractMinimally invasive procedures are more and more becoming the standard treatment for many surgical procedures such as the treatment of cerebral aneurysms. In an endovascular procedure the aneurysm is filled with flexible platinum coils leading to embolization and blocking the blood flow in the aneurysm. This established treatment needs high skills and experience on the surgeon. In order to practice and plan a specific procedure or test a new device, a realistic simulation environment is needed. Modern 3D printing technology allows the fabrication of patient specific models incorporating the exact geometry of the pathological anatomy. This article describes the development of a low-cost physiological simulation system for the training of the endovascular treatment of aneurysms. In order to practice the procedure in a realistic scenario, a 3D printed model of the aneurysm is embedded in a fluidic simulation s ystem. In addition to the patient-specific anatomy of the aneurysm a pulsatile water flow is generated, which emulates the influence of blood flow on the behaviour of catheters and coils during deployment. The system consist of a controllable pump circuit generating a pulsatile flow which can be regulated automatically and additionally controlled externally by the user. For a suitable representation, a display which graphically represents the sensor data and settings is employed. The components were compactly integrated in a small case allowing for easy deployment in training workshops. The simulation setup was successfully tested in prospective patient specific treatment planning and workshops for students.

Abstract:

Brief descriptions are provided of a new cost-effectiveness analysis program, known as the Roadside Safety Analysis Program (RSAP), which was developed under NCHRP Project 22-9. RSAP is an improvement over existing cost-effectiveness analysis procedures for evaluation of roadside safety improvements, such as the procedures in the 1977 AASHTO barrier guide and the ROADSIDE program. RSAP improves on many of the algorithms in the procedures and provides a user-friendly interface to facilitate use. The program has undergone extensive testing and validation, including evaluation by an independent reviewer. It is anticipated that RSAP will be available to the public through the McTrans Center at the University of Florida.

Abstract:

Objectives: The objective of this study was to evaluate the success of fat graft myringoplasty and to discuss the utilities and advantages of a fat graft in primary versus revision myringoplasties.Methods: Eighteen patients who had not had previous otological surgery, and twelve patients whose tympanic membrane perforations have persisted despite myringoplasty with temporalis fascia were included in this prospective clinical trial. All patients were treated by fat graft myringoplasty and followed up for one year.Results: Successful closure of the perforation was obtained in 82.4 per cent of the ears at the final follow up. The success rate in the group of patients who had not had previous otological surgery was higher than those of revision cases.Conclusions: Adipose tissue provides the basic requirements for grafting of the tympanic membrane, with its own favourable characteristics. Fat graft myringoplasty is a cost-effective alternative in small perforations of the tympanic membrane, including revision cases.

Abstract:

Objective Eustachian tube dysfunction (ETD) is a common diagnosis among adults presenting for outpatient care. We sought to determine national utilization and the associated cost of invasive procedures for adult ETD. Study Design Cross-sectional study. Setting National health care database. Subjects and Methods The Truven Health MarketScan Databases (2010-2014) analytic cohort included health care encounters of patients ≥18 years of age with a diagnosis of ETD or related conditions of otitis media with effusion (OME) or tympanic membrane retraction (TMR). Visits associated with recent diagnoses of acute upper respiratory infection, head and neck cancer, or radiation therapy were excluded. Invasive procedure usage was subdivided into nasal and otologic procedures. Results ETD, OME, or TMR was diagnosed in 1,298,987 patients, 11.1% of which were chronic. The most common procedure was diagnostic endoscopy (including nasal endoscopy and laryngopharyngoscopy), which was used most frequently in the first 3 months after diagnosis, during which it was performed in 120,971 (9.3%) patients. The most frequent therapeutic nasal procedure was eustachian tube inflation without catheterization, performed in 11,412 patients over 5 years at a total cost of $1,210,939 ($106 per person annually). The most common therapeutic otologic procedure was myringotomy with tympanostomy, performed on 56,137 patients over 5 years at a total cost of $47,713,708 ($810 per person annually). Conclusion Several nasal and otologic procedures are associated with a diagnosis of adult ETD at substantial cost. Development of therapeutic alternatives should be sought to mitigate the need for invasive procedures to treat this condition.

Abstract:

ABSTRACT Objective: To compare patient experience, chairside time, dental arch distances, and costs of dental models derived from intraoral scans and alginate impressions in pre-orthodontic children and young adolescents. Materials and Methods: Fifty-nine children and young adolescents (9–15 years, mean: 12.70 years) had an intraoral scan and an alginate impression prior to orthodontic treatment. During the procedures, chairside time was registered in minutes and patient experience was assessed by a Visual Analogue Scale questionnaire. Four maxillary dental arch distances were measured on digital models, on plaster casts, and directly in the mouth (intraoral). The cost of each procedure was presented graphically. Differences between the two procedures were tested by paired t-test and general linear model. Results: Patient experience was statistically better during intraoral scan compared with alginate impression regarding comfort, gag reflex, breathing, smell/sound, taste/vibration, and all statements concerning anxiety (P &lt; .05). No significant difference in chairside time between the two procedures was found. No statistically significant differences in dental arch distances between digital models and plaster casts were found, but dental arch distances measured intraorally differed significantly from both digital models and plaster casts (P &lt; .05). Cost calculation showed that the digital procedure was 10.7 times more expensive than the conventional procedure initially and, that after 3.6 years, the two procedures were equal in cost. Conclusions: Children preferred intraoral scan rather than alginate impression. Chairside time was equal for the two procedures as were the measurements of maxillary dental arch distances. The two procedures were equal in cost at 3.6 years.

Abstract:

Purpose: Congenital dacrocystocele with potential for dacryocystitis are common ophthalmic findings in children. There are multiple surgical approaches to open the mucocele. In this study, we look at the financial impact of these different approaches. Methods: A retrospective chart review of 17 patients with dacrocystocele or dacryocystitis was performed. We examined four approaches: (1) bedside nasal endoscopy with marsupialization of nasolacrimal duct (NLD) cyst, (2) surgically performed nasal endoscopy with marsupialization of NLD cyst, (3) NLD probe, and (4) a combination of procedures. Cost of the procedure and length of anesthesia were collected. Reoccurrence of symptoms and disease post-procedure were also collected. Results: The lowest cost billed procedure was bedside nasal endoscopy performed by an otolaryngologist (US$435; n = 1). A nasal endoscopy ( n = 2) performed in the operating room (OR) had an average OR fee of US$14,557 [standard deviation (SD): US$7598] for 108.5 (SD: 87.0) min of operating time. An NLD probe ( n = 5) performed by pediatric ophthalmologists resulted in an average OR fee of US$5540 (SD: US$1752) for 31.0 min (SD: 8.6 min) of operating time. A combination of both nasal endoscopy and NLD probing ( n = 9) had an average OR fee US$10,325 (SD: US$4137) for 69 min (SD: 34.5 min) of operating time. Conclusion: This is the first study looking at cost benefit of four different approaches to treating dacrocystoceles/dacryocystitis. A NLD probe was a low-cost OR intervention and had the shortest operating time. The combination procedure was more cost-effective than nasal endoscopy or NLD probing alone.

Abstract:

e12083 Background: Percutaneous core-needle biopsy (PCNB) is the standard of care to diagnose suspicious lesions of the breast. Dependent upon histology, many women require additional open procedures for definitive diagnosis and excision. However, there remains little nationally-representative research on the proportion of women undergoing multiple open biopsy or lumpectomy procedures and the associated incremental burden to the health system. Methods: This study used Medicare 100% Standard Analytic Files (2010–2014) to identify patients undergoing PCNB in an outpatient setting. Patients included females aged ≥65; continuous Medicare enrollment; no history of cancer, chemotherapy, radiation or breast cancer surgery in the prior year. Open procedures were defined as an open biopsy or lumpectomy. Study follow-up was defined as 90 days from initial PCNB or until the day prior to chemotherapy, radiation, or mastectomy—to limit analysis to diagnosis-related payments. Payments were defined as Medicare payments. Results: 110,944 patients were identified; the mean age was 73.5; 74.1% underwent only PCNB, 23.8% had one open procedure and 2.1% had multiple open procedures. Among the PCNB-only cohort, 2.7% had multiple PCNBs; among those with subsequent open procedures, 4.1-4.4% had multiple PCNBs (P < .001). Incidence of all-cause complications was significantly lower among those with no open procedure (8%) versus those with one (11%) or more (20%, P < .001). Mean incremental breast-related payments were $3003 greater among those with one open procedure versus none ($4526 v $1523, P < .001), and $1978 greater among those with multiple open procedures ($6504 v $4526, P < .001). Prior receipt of multiple PCNBs and diagnosis of breast cancer were significantly positively correlated in logistic regression with having multiple open procedures, while age ≥ 80 was a negative predictor. Conclusions: There continues to be a percentage of women that require multiple open procedures following initial biopsy. These results suggest that incomplete excision at the first open procedure remains a meaningful concern, and merits further investigation into methods to ensure excisional completeness.
