RESUMO

Using an age- and comorbidity-matched cohort, we compared patients who underwent unicompartmental knee arthroplasty in an ambulatory surgery center with those who underwent the procedure in a traditional hospital inpatient setting. Postoperatively, the ambulatory surgery center cohort had fewer major complications than the inpatient cohort. No ambulatory surgery center patients required acute hospital admission and none had major complications. Four major complications occurred in the inpatient cohort. There was no difference in complication rates. Our results suggest that outpatient unicompartmental knee arthroplasty in a freestanding ambulatory surgery center is a safe and reasonable alternative to the traditional inpatient hospital setting.

RESUMO

Total knee arthroplasty (TKA) is a frequent operation in Germany and in 2017 a total of 191,272 interventions were carried out. These interventions are associated with high costs and involve complex clinical workflow organization and time-consuming instrument logistics. With this in mind, the aim of this study was to identify the economic potential of the instrument configuration in order to optimize the entire process in TKA. Changing the composition of the set of instruments used in the operating theater for TKA resulted in time and cost saving for the complete TKA procedure, including all personnel and off-shoot procedures. In addition, the operating time saved by the introduction of a patient-specific instrumentation set meant that the operating theater could be used for more or other surgical procedures, also generating additional revenue.

RESUMO

AIMS: The practice of alternating operating theatres has long been used to reduce surgeon idle time between cases. However, concerns have been raised as to the safety of this practice. We assessed the payments and outcomes of total knee arthroplasty (TKA) performed during overlapping and nonoverlapping days, also comparing the total number of the surgeon's cases and the total time spent in the operating theatre per day. MATERIALS AND METHODS: A retrospective analysis was performed on the Centers for Medicare & Medicaid Services (CMS) Limited Data Set (LDS) on all primary elective TKAs performed at the New England Baptist Hospital between January 2013 and June 2016. Using theatre records, episodes were categorized into days where a surgeon performed overlapping and nonoverlapping lists. Clinical outcomes, economic outcomes, and demographic factors were calculated. A regression model controlling for the patient-specific factors was used to compare groups. Total orthopaedic cases and aggregate time spent operating (time between skin incision and closure) were also compared. RESULTS: A total of 3633 TKAs were performed (1782 on nonoverlapping days; 1851 on overlapping days). There were no differences between the two groups for length of inpatient stay, payments, mortality, emergency room visits, or readmission during the 90-day postoperative period. The overlapping group had 0.74 fewer skilled nursing days (95% confidence interval (CI) -0.26 to -1.22; p < 0.01), and 0.66 more home health visits (95% CI 0.14 to 1.18; p = 0.01) than the nonoverlapping group. On overlapping days, surgeons performed more cases per day (5.01 vs 3.76; p < 0.001) and spent more time operating (484.55 minutes vs 357.17 minutes; p < 0.001) than on nonoverlapping days. CONCLUSION: The study shows that the practice of alternating operating theatres for TKA has no adverse effect on the clinical outcome or economic utilization variables measured. Furthermore, there is opportunity to increase productivity with alternating theatres as surgeons with overlapping cases perform more cases and spend more time operating per day.

RESUMO

AIMS: The primary aim of the study was to perform an analysis to identify the cost per quality-adjusted life-year (QALY) of robot-assisted unicompartmental knee arthroplasty (rUKA) relative to manual total knee arthroplasty (TKA) and unicompartmental knee arthroplasty (UKA) for patients with isolated medial compartment osteoarthritis (OA) of the knee. Secondary aims were to assess how case volume and length of hospital stay influenced the relative cost per QALY. PATIENTS AND METHODS: A Markov decision analysis was performed, using known parameters for costs, outcomes, implant survival, and mortality, to assess the cost-effectiveness of rUKA relative to manual TKA and UKA for patients with isolated medial compartment OA of the knee with a mean age of 65 years. The influence of case volume and shorter hospital stay were assessed. RESULTS: Using a model with an annual case volume of 100 patients, the cost per QALY of rUKA was £1395 and £1170 relative to TKA and UKA, respectively. The cost per QALY was influenced by case volume: a low-volume centre performing ten cases per year would achieve a cost per QALY of £7170 and £8604 relative to TKA and UKA. For a high-volume centre performing 200 rUKAs per year with a mean two-day length of stay, the cost per QALY would be £648; if performed as day-cases, the cost would be reduced to £364 relative to TKA. For a high-volume centre performing 200 rUKAs per year with a shorter length of stay of one day relative to manual UKA, the cost per QALY would be £574. CONCLUSION: rUKA is a cost-effective alternative to manual TKA and UKA for patients with isolated medial compartment OA of the knee. The cost per QALY of rUKA decreased with reducing length of hospital stay and with increasing case volume, compared with TKA and UKA. Cite this article: Bone Joint J 2019;101-B:1063-1070.

RESUMO

BACKGROUND: In total joint arthroplasty, variation in implant use can be driven by vendor relationships, surgeon preference, and technological advancements. Our institution developed a preferred single-vendor program for primary hip and knee arthroplasty. We hypothesized that this initiative would decrease implant costs without compromising performance on quality metrics. METHODS: The utilization of implants from the preferred vendor was evaluated for the first 12 months of the contract (September 1, 2017, to August 31, 2018; n = 4,246 cases) compared with the prior year (September 1, 2016, to August 31, 2017; n = 3,586 cases). Per-case implant costs were compared using means and independent-samples t tests. Performance on quality metrics, including 30-day readmission, 30-day surgical site infection (SSI), and length of stay (LOS), was compared using multivariable-adjusted regression models. RESULTS: The utilization of implants from the preferred vendor increased from 50% to 69% (p < 0.001), with greater use of knee implants than hip implants from the preferred vendor, although significant growth was seen for both (from 62% to 81% for knee, p < 0.001; and from 38% to 58% for hip, p < 0.001). Adoption of the preferred-vendor initiative was greatest among low-volume surgeons (from 22% to 87%; p < 0.001) and lowest among very high-volume surgeons (from 61% to 62%; p = 0.573). For cases in which implants from the preferred vendor were utilized, the mean cost per case decreased by 23% in the program's first year (p < 0.001), with an associated 11% decrease in the standard deviation. Among all cases, there were no significant changes with respect to 30-day readmission (p = 0.449) or SSI (p = 0.059), while mean LOS decreased in the program's first year (p < 0.001). CONCLUSIONS: The creation of a preferred single-vendor model for hip and knee arthroplasty implants led to significant cost savings and decreased cost variability within the program's first year. Higher-volume surgeons were less likely to modify their implant choice than were lower-volume surgeons. Despite the potential learning curve associated with changes in surgical implants, there was no difference in short-term quality metrics. LEVEL OF EVIDENCE: Therapeutic Level III.

RESUMO

BACKGROUND: Late-stage isolated medial knee osteoarthritis can be treated with total knee replacement (TKR) or partial knee replacement (PKR). There is high variation in treatment choice and little robust evidence to guide selection. The Total or Partial Knee Arthroplasty Trial (TOPKAT) therefore aims to assess the clinical effectiveness and cost-effectiveness of TKR versus PKR in patients with medial compartment osteoarthritis of the knee, and this represents an analysis of the main endpoints at 5 years. METHODS: Our multicentre, pragmatic randomised controlled trial was done at 27 UK sites. We used a combined expertise-based and equipoise-based approach, in which patients with isolated osteoarthritis of the medial compartment of the knee and who satisfied general requirements for a medial PKR were randomly assigned (1:1) to receive PKR or TKR by surgeons who were either expert in and willing to perform both surgeries or by a surgeon with particular expertise in the allocated procedure. The primary endpoint was the Oxford Knee Score (OKS) 5 years after randomisation in all patients assigned to groups. Health-care costs (in UK 2017 prices) and cost-effectiveness were also assessed. This trial is registered with ISRCTN (ISRCTN03013488) and ClinicalTrials.gov (NCT01352247). FINDINGS: Between Jan 18, 2010, and Sept 30, 2013, we assessed 962 patients for their eligibility, of whom 431 (45%) patients were excluded (121 [13%] patients did not meet the inclusion criteria and 310 [32%] patients declined to participate) and 528 (55%) patients were randomly assigned to groups. 94% of participants responded to the follow-up survey 5 years after their operation. At the 5-year follow-up, we found no difference in OKS between groups (mean difference 1·04, 95% CI -0·42 to 2·50; p=0·159). In our within-trial cost-effectiveness analysis, we found that PKR was more effective (0·240 additional quality-adjusted life-years, 95% CI 0·046 to 0·434) and less expensive (-£910, 95% CI -1503 to -317) than TKR during the 5 years of follow-up. This finding was a result of slightly better outcomes, lower costs of surgery, and lower follow-up health-care costs with PKR than TKR. INTERPRETATION: Both TKR and PKR are effective, offer similar clinical outcomes, and result in a similar incidence of re-operations and complications. Based on our clinical findings, and results regarding the lower costs and better cost-effectiveness with PKR during the 5-year study period, we suggest that PKR should be considered the first choice for patients with late-stage isolated medial compartment osteoarthritis.

RESUMO

PURPOSE OF THE STUDY The study aims to quantify the costs of a hospital stay of patients with total knee periprosthetic joint infection throughout the period of treatment. MATERIAL AND METHODS The group included patients who have been treated at our department for infection as a complication of total knee replacement since 1 January 2011, who have been provided with treatment (including complications) exclusively at the departments of Nemocnice Ceské Budejovice, a.s. and whose treatment can be considered completed in 2018. The patients were included in the study regardless of the type of infection and method of treatment. The group consisted of 24 patients (11 men and 13 women). There were 2 cases of early postoperative infection, 6 cases of late postoperative infection and 16 cases of hematogenous infection. The group includes 17 patients treated by a two-stage reimplantation, 6 patients treated by a revision surgery with implant retention, and 1 patient treated by a one-stage replacement. In selected patients, all the reported points for all the hospital stays and costs incurred on a separately charged material were ascertained and the final sum was compared with the reimbursement obtained by the hospital in the DRG system valid for the respective year of treatment. The total costs were analysed and moreover, an analysis by type of infection and method of treatment was carried out. RESULTS The average costs of managing infection as a complication of TKA in our department amounted to CZK 405 864 (CZK 66 768-CZK 181 17). The average cost of a two-stage revision was CZK 497 487, the cost of a revision surgery with original implant retention was CZK 175 312. The reimbursement in respect of the monitored cases in the DRG system equalled CZK 276 230 (CZK 40 943-CZK 848 401). The aforementioned suggests that the average loss per a treated patient is CZK 129 635 (CZK + 26 066Kc-CZK -332 774). DISCUSION Our study is in agreement with recent literature, when confirming that the care associated with infections as a complication of TKA is very costly (especially in case of a two-stage reimplantation) and also that this care is not fully covered by the health insurance company. The reimbursement made by the health insurance companies does not cover on average 1/3 of the costs of care for an infectious patient. Theoretically, the reasons behind the reduced reimbursement may be sanctions which, however, cannot be accepted in case of late hematogenous infections which constituted more than 50% in our group. CONCLUSIONS Our study presented the actual costs associated with the care of TKA infection. It makes sense that the most expensive is the two-stage reimplantation, which is nevertheless still considered to be the gold standard procedure in chronic TKA infection. High costs of therapy together with the requirement of expert care would justify the introduction of care provided by specialised centres. In this case, centralisation could result in a more efficient use of funds and improvement of the quality of provided care.

RESUMO

AIMS: The Bundled Payments for Care Improvement (BPCI) initiative has identified pathways for improving the value of care. However, patient-specific modifiable and non-modifiable risk factors may increase costs beyond the target payment. We sought to identify risk factors for exceeding our institution's target payment, the so-called 'bundle busters'. PATIENTS AND METHODS: Using our data warehouse and Centers for Medicare and Medicaid Services (CMS) data we identified all 412 patients who underwent total joint arthroplasty and qualified for our institution's BPCI model, between July 2015 and May 2017. Episodes where CMS payments exceeded the target payment were considered 'busters' (n = 123). Risk ratios (RRs) were calculated using a modified Poisson regression analysis. RESULTS: An increased risk of exceeding the target payment was significantly associated with increasing age (adjusted RR 1.04, 95% confidence interval (CI) 1.01 to 1.06) and body mass index (adjusted RR 1.03, 95% CI 1.003 to 1.06). Eight comorbid risk factors were also identified (all p < 0.05), only two of which were considered to be potentially modifiable (diabetes with complications and preoperative anaemia). An American Society of Anesthesiologist physical status classification system (ASA) score ≥ 3 (adjusted RR 2.3, 95% CI 1.67 to 3.18) and Charlson Comorbidity Index (CCI) ≥ 3 (adjusted RR 1.94, 95% CI 1.45 to 2.60) were risk factors for bundle busting. CONCLUSION: Non-modifiable preoperative risk factors can increase costs and exceed the target payment. Future bundled payment models should incorporate the stratification of risk.

RESUMO

AIMS: The aim of this study was to compare the actual cost of a cemented and cementless total knee arthroplasty (TKA) procedure. MATERIALS AND METHODS: The cost of operative time, implants, cement, and cementing accessories were included in the overall cost of the TKA procedure. Operative time was determined from a previously published study comparing cemented and cementless implants of the same design. The cost of operative time, implants, cement, and cementing accessories was determined from market and institutional data. RESULTS: Mean operative time for cemented TKA was 11.6 minutes longer for cemented TKA than cementless TKA (93.7 minutes (sd 16.7) vs 82.1 minutes (sd 16.6); p = 0.001). Using a conservative published standard of $36 per minute for operating theatre time cost, the total time cost was $418 higher for cementing TKA. The cost of cement and accessories ranged from $170 to $625. Overall, the calculated cost of cemented TKA is $588 to $1043, depending on technique. The general increased charge for cementless TKA implants over cemented TKA implants was $366. CONCLUSION: The overall procedural cost of implanting a cementless TKA is less than implanting a cemented TKA. Cost alone should not be a barrier to using cementless TKA.

RESUMO

INTRODUCTION: Total knee arthroplasty (TKA) is one of the most commonly performed orthopedic procedures. During the past decade, patient-specific instrumentation (PSI) has been commercially introduced in order to simplify and make TKA surgery more effective, precise and efficient than conventional mechanical instrumentation (CI) and computer-assisted surgery (CAS). Nevertheless, there are critical arguments against PSI for routine use. The aim of the current manuscript is to describe advantages and limitations of PSI for primary TKA. AREAS COVERED: By means of a description of the available literature different aspects are discussed (accuracy, clinical and functional outcomes, operative time, blood loss, efficiency and costs). EXPERT OPINION: Most publications do not claim a significant increase in PSI accuracy over CI, but they also do not postulate PSIs accuracy is worse either. Regarding clinical aspects, PSI did not appear to give any advantage over standard techniques although, equally, it did not appear to show any disadvantages. PSI seems to reduce operative time, could reduce perioperative blood loss and provides logistical benefits in the operation room. Further studies will be required to more thoroughly assess all the advantages and disadvantages of this promising technology as an alternative to CI and CAS.

RESUMO

BACKGROUND: Recent policy initiatives, including Bundled Payments for Care Improvement (BPCI) Initiative by the Centers for Medicare and Medicaid Health Services (CMS), encourage healthcare providers to manage the total episode of care, rather than just the surgical episode. Surgical site infections (SSI) following total joint replacement result in preventable morbidity and suffering for patients and excess healthcare utilization for healthcare providers. This study sought to estimate the additional resources associated with SSIs within the 90-day episode of care following hip and knee joint replacement. METHODS: Using the 2013 Nationwide Readmissions Database (NRD), healthcare resource utilization was compared between propensity score matched patient groups with and without SSI-related readmissions within the 90-day episode of care following total joint replacement. RESULTS: Surgical site infections were associated with significantly longer hospital length of stay and increased costs following hip and knee joint replacement procedures. Generalized estimating equation regression results confirmed that additional costs associated with SSIs following both cohorts were significant, with additional hospital length of stay and costs following total hip and knee replacement procedures ranging from 4.9 to 5.2 days and $12,689 to $12,890, respectively. CONCLUSION: Surgical site infections following total joint replacement account for significant additional healthcare resource use within the 90-day episode of care.

RESUMO

AIMS: The purpose of the present study was to compare patient-specific instrumentation (PSI) and conventional surgical instrumentation (CSI) for total knee arthroplasty (TKA) in terms of early implant migration, alignment, surgical resources, patient outcomes, and costs. PATIENTS AND METHODS: The study was a prospective, randomized controlled trial of 50 patients undergoing TKA. There were 25 patients in each of the PSI and CSI groups. There were 12 male patients in the PSI group and seven male patients in the CSI group. The patients had a mean age of 69.0 years (sd 8.4) in the PSI group and 69.4 years (sd 8.4) in the CSI group. All patients received the same TKA implant. Intraoperative surgical resources and any surgical waste generated were recorded. Patients underwent radiostereometric analysis (RSA) studies to measure femoral and tibial component migration over two years. Outcome measures were recorded pre- and postoperatively. Overall costs were calculated for each group. RESULTS: There were no differences (p > 0.05) in any measurement of migration at two years for either the tibial or femoral components. Movement between one and two years was < 0.2 mm, indicating stable fixation. There were no differences in coronal or sagittal alignment between the two groups. The PSI group took a mean 6.1 minutes longer (p = 0.04) and used a mean 3.4 less trays (p < 0.0001). Total waste generated was similar (10 kg) between the two groups. The PSI group cost a mean CAD$1787 more per case (p < 0.01). CONCLUSION: RSA criteria suggest that both groups will have revision rates of approximately 3% at five years. The advantages of PSI were minimal or absent for surgical resources used and waste eliminated, and for meeting target alignment, yet had significantly greater costs. Therefore, we conclude that PSI may not offer any advantage over CSI for routine primary TKA cases. Cite this article: Bone Joint J 2019;101-B:565-572.

RESUMO

AIMS: The purpose of this study was to compare outcomes of combined total joint arthroplasty (TJA) (total hip arthroplasty (THA) and total knee arthroplasty (TKA) performed during the same admission) versus bilateral THA, bilateral TKA, single THA, and single TKA. Combined TJAs performed on the same day were compared with those staged within the same admission episode. PATIENTS AND METHODS: Data from the National (Nationwide) Inpatient Sample recorded between 2005 and 2014 were used for this retrospective cohort study. Postoperative in-hospital complications, total costs, and discharge destination were reviewed. Logistic and linear regression were used to perform the statistical analyses. p-values less than 0.05 were considered statistically significant. RESULTS: Combined TJA was associated with increased risk of deep vein thrombosis, prosthetic joint infection, irrigation and debridement procedures, revision arthroplasty, length of stay (LOS), and in-hospital costs compared with bilateral THA, bilateral TKA, single THA, and single TKA. Combined TJA performed on separate days of the same admission showed no statistically significant differences when compared with same-day combined TJA, but trended towards decreased total costs and total complications despite increased LOS. CONCLUSION: Combined TJA is associated with increased in-hospital complications, LOS, and costs. We do not recommend performing combined TJA during the same hospital stay.

RESUMO

BACKGROUND: Total knee arthroplasty is a commonly performed procedure and an important contributor to national health care spending. Reducing the incidence of readmission could have important consequences for patient well-being and relevant financial implications. Whether regional anesthesia techniques are associated with decreased readmission rates and costs among privately insured patients remains unknown. METHODS: Using administrative claims data, we identified 138,362 privately insured patients 18-64 years of age who underwent total knee arthroplasty between 2002 and 2013. We then examined whether the use of a nerve block was associated with decreases in readmission rates and related costs during the 90 days after discharge. Our analyses were adjusted for potential confounding variables including medical comorbidities and previous use of opioids and other medications. RESULTS: After adjusting for patient demographics, comorbidities, and preoperative medication use, the adjusted 90-day readmission rate was 1.8% (95% confidence interval [CI], 1.1-2.4) among patients who did not receive a block compared to 1.7% (95% CI, 1.1-2.4) among patients who did (odds ratio, 0.99; 95% CI, 0.91-1.09; P = .85). The adjusted readmission-related postoperative cost for patients who did not receive a block was $561 (95% CI, 502-619) and $574 (95% CI, 508-639) for patients who did (difference, $13; 95% CI, -75 to 102; P = .74). This lack of statistically significant differences held for subgroup and sensitivity analyses. CONCLUSIONS: Nerve blocks were not associated with improved measures of long-term postoperative resource use in this younger, privately insured study population.

RESUMO

INTRODUCTION: Hip and knee arthroplasty are high volume, clinically successful, but costly orthopedic surgical procedures. There is significant variation in volume, outcomes, and cost at various hospitals. METHODS: Using the Statewide Planning and Research Cooperative System (SPARCS) database to determine readmission rates and the New York State Department of Health (NYSDoH) hospital cost transparency database to obtain costs, we reviewed this data for hip and knee replacements to determine if there was a relationship between volume of procedures performed and cost or readmission rates. RESULTS: The readmission rate increased with increasing cost for facilities performing total knee arthroplasty (p = 0.02). Readmission rate did not change significantly with volume of procedures performed. Similarly, the readmission rate increased with increasing cost for facilities performing total hip arthroplasty but did not change significantly with respect to volume (p < 0.01). CONCLUSION: Spending more money to perform total hip and knee arthroplasty in New York State does not ensure lower readmission rates. Readmission rates vary independent of volume of procedures performed. Total hip and knee arthroplasty are two of the most successful and commonly performed orthopedic surgical procedures. Outcome investigations demonstrate reliable pain relief and consistently good or excellent functional outcomes.1-3 However, there is significant variability in both cost and quality of these procedures, resulting in a wide difference in their value. Porter defines value as outcomes divided by cost.4 One metric that reflects both the cost as well as the quality of care is the unplanned readmission rate. Whether readmission occurs as a result of thromboembolic disease, surgical site infection, or cardiopulmonary complications in the postoperative period, it represents a deterioration of outcome at a significant cost burden to the treating institution. The New York State Department of Health's Statewide Planning and Research Cooperative System (SPARCS) database was established in 1979. Licensed hospitals in the state are mandated to report data on all discharges, including inpatient and outpatient surgery procedures and emergency department admissions.5 On December 5, 2013, the New York State Department of Health made hospital-specific average costs for over 300 diagnosis-related groups (DRGs) available publicly on its website.6 Among the selected DRGs were total hip (301) and total knee (302) arthroplasty. The purpose of this study was to determine if there was a relationship between quality (as indicated by readmission rate) and either volume of procedures performed or cost of performing those procedures.

RESUMO

OBJECTIVES: To investigate the impact of insurance coverage on the adoption of customized individually made (CIM) knee implants and to compare patient outcomes and cost effectiveness of off-the-shelf and CIM implants. METHODS: A system dynamics simulation model was developed to study adoption dynamics of CIM and meet the research objectives. The model reproduced the historical data on primary and revision knee replacement implants obtained from the literature and the Nationwide Inpatient Sample. Then the dynamics of adoption of CIM implants were simulated from 2018 to 2026. The rate of 90-day readmission, 3-year revision surgery, recovery period, time savings in operating rooms, and the associated cost within 3 years of primary knee replacement implants were used as performance metrics. RESULTS: The simulation results indicate that by 2026, an adoption rate of 90% for CIM implants can reduce the number of readmissions and revision surgeries by 62% and 39%, respectively, and can save hospitals and surgeons 6% on procedure time and cut down cumulative healthcare costs by approximately $38 billion. CONCLUSIONS: CIM implants have the potential to deliver high-quality care while decreasing overall healthcare costs, but their adoption requires the expansion of current insurance coverage. This work presents the first systematic study to understand the dynamics of adoption of CIM knee implants and instrumentation. More broadly, the current modeling approach and systems thinking perspective could be used to consider the adoption of any emerging customized therapies for personalized medicine.

RESUMO

BACKGROUND: In Europe few studies have analyzed the costs of treating aseptic revisions and prosthetic joint infections with either debridement, antibiotics and implant retention or two-stage revision, as compared to the cost of a primary total joint arthroplasty. METHODS: The purpose was to analyze the costs of total joint arthroplasties, aseptic revisions and prosthetic joint infections treated with debridement, antibiotics and implant retention or a two-stage revision. We conducted a retrospective cohort study of patients who had a total joint arthroplasty in the Oulu University Hospital during the three-year period from 2013 to 2015. The costs were divided to specific services (e.g. procedure costs, ward care costs, laboratory). Actual costs obtained from the hospital's financial database were used for analysis. RESULTS: There were 1708 total joint arthroplasties without complications, 18 aseptic revisions and 42 prosthetic joint infections eligible for analysis. The mean cost of a total joint arthroplasty was €7200, the excess cost of an aseptic revision was €10,900 and the excess cost of a prosthetic joint infection was €18,900 (total joint arthroplasty vs. infection, p < .0001). The excess cost was €12,800 for debridement, antibiotics and implant retention treatment and €44,600 for a two-stage revision (p < .0001). The two most expensive services were ward care and procedures. CONCLUSIONS: Infection tripled the cost of a total joint arthroplasty. The cost of two-stage revisions were triple that of debridement, antibiotics and implant retention treatment.

RESUMO

BACKGROUND: Sleep apnea (SA) negatively affects bone mineralization, cognition, and immunity. There is paucity in the literature regarding the impact of SA on total joint arthroplasty (TJA). The purpose of this study is to compare complications in patients with and without SA undergoing either total knee (TKA) or total hip arthroplasty (THA). METHODS: A retrospective review from 2005 to 2014 was conducted using the Medicare Standard Analytical Files. Patients with and without SA on the day of the primary TJA were queried using the International Classification of Diseases, ninth revision codes. Patients were matched by age, gender, Charlson Comorbidity Index), and body mass index. Patients were followed for 2 years after their surgery. Ninety-day medical complications, complications related to implant, readmission rates, length of stay, and 1-year mortality were quantified and compared. Logistic regression was used to calculate odds ratios (OR) with their respective 95% confidence interval and P values. RESULTS: After the random matching process there were 529,240 patients (female = 271,656, male = 252,106, unknown = 5478) with (TKA = 189,968, THA = 74,652) and without (TKA = 189,968, THA = 74,652) SA who underwent primary TJA between 2005 and 2014. Patients with SA had greater odds of developing medical complications following TKA (OR 3.71) or THA (OR 2.48). CONCLUSION: The study illustrates an increased risk of developing postoperative complications in patients with SA following primary TJA. Surgeons should educate patients on these adverse effects and encourage the use of continuous positive airway pressure which has been shown to mitigate many postoperative complications.

RESUMO

Optimizing surgical instrumentation may contribute to value-based care, particularly in commonly performed procedures. We report our experience in implementing a perioperative efficiency program in 2 types of orthopedic surgery (primary total-knee arthroplasty, TKA, and total-hip arthroplasty, THA).A comparative before-and-after study with 2 participating surgeons, each performing both THA and TKA, was conducted. Our objective was to evaluate the effect of surgical tray optimization on operating and processing time, cost, and waste associated with preparation, delivery, and staging of sterile surgical instruments. The study was designed as a prospective quality improvement initiative with pre- and postimplementation operational measures and a provider satisfaction survey.A total of 96 procedures (38 preimplementation and 58 postimplementation) were assessed using time-stamped performance endpoints. The number and weight of trays and instruments processed were reduced substantially after the optimization intervention, particularly for TKA. Setup time was reduced by 23% (6 minutes, P = .01) for TKA procedures but did not differ for THA. The number of survey respondents was small, but satisfaction was high overall among personnel involved in implementation.Optimizing instrumentation trays for orthopedic procedures yielded reduction in processing time and cost. Future research should evaluate patient outcomes and incremental/additive impact on institutional quality measures.
