The nationwide epidemiological and health insurance disease burden of knee and lower leg injuries in Hungary / A térd- és lábszársérülések okozta országos epidemiológiai és egészségbiztosítási betegségteher Magyarországon.

Összefoglaló. Bevezetés: A térd és a lábszár sérülései jelentos terhet jelentenek az egyén és a társadalom számára. Célkituzés: Elemzésünk célja volt a térd- és lábszársérülés okozta éves epidemiológiai és egészségbiztosítási betegségteher vizsgálata Magyarországon. Adatok és módszerek: Az elemzésben felhasznált adatok a Nemzeti Egészségbiztosítási Alapkezelo (NEAK) finanszírozási adatbázisából származnak, és a 2018. évet fedik le. Vizsgáltuk az éves egészségbiztosítási kiadásokat, azok megoszlását, az éves betegszámot, valamint a 100 000 lakosra vetített prevalenciát korcsoportok és nemek szerinti bontásban. A térd és a lábszár sérülései kórképeket a Betegségek Nemzetközi Osztályozása (BNO, 10. revízió) szerinti S80-S89-es kóddal azonosítottuk. Eredmények: A legköltségesebb ellátási forma az aktívfekvobeteg-szakellátás volt, amelynek országos betegszáma összesen 18 398 fo (9868 fo férfi, 8530 fo no) volt. Az aktívfekvobeteg-szakellátás betegforgalmi adatai alapján a 100 000 fore eso prevalencia a férfiaknál 211,2 fo, a noknél 167,0 fo, együtt 188,1 fo volt. A NEAK 8,808 milliárd Ft-ot költött 2018-ban a térd- és lábszársérülések kezelésére, ami 32,59 millió USD-nak, illetve 27,62 millió EUR-nak felelt meg. Az aktívfekvobeteg-szakellátás a teljes egészségbiztosítási kiadás 61,4%-ával volt a legmeghatározóbb költségelem. A kiadások 52,0%-a férfiaknál, míg 48,0%-a noknél jelent meg. A 49. életévig a férfiak, míg az 50. életév feletti korosztályban a nok sérüléseibol származó ellátások betegszámai és költségei a magasabbak. Következtetés: Az aktívfekvobeteg-szakellátás bizonyult a fo költségtényezonek. A betegség elofordulási gyakorisága 26%-kal volt magasabb a férfiak esetében, mint a noknél. Orv Hetil. 2021; 162(Suppl 1): 54-60. INTRODUCTION: Injuries to the knee and lower leg pose a great burden for the individual and society. OBJECTIVE: The aim of our study was to determine the annual epidemiological disease burden and the health insurance treatment cost of knee and lower leg injuries in Hungary. DATA AND METHODS: Data were derived from the financial database of the National Health Insurance Fund Administration (NHIFA) of Hungary for the year 2018. The data analysed included annual health insurance costs and their distribution and annual patient numbers and prevalence per 100 000 population calculated for age groups and sex. Patients with knee and lower leg injuries were identified with the following code of the International Classification of Diseases, 10th revision: S80-S89. RESULTS: The most expensive insurance treatment category was acute inpatient care, presenting 18 398 patients in total (9868 men, 8530 women). Based on patient numbers in acute inpatient care, the prevalence in 100 000 population among men was 211.2 patients, among women 167.0 patients, in total 188.1 patients. In 2018, NHIFA spent 8.808 billion HUF on the treatment of patients with knee and lower leg injuries (32.59 million USD, 27.62 million EUR). Acute inpatient care with 61.4% of the total health insurance expenditure was the main cost driver. 52.0% of the costs was spent on the treatment of male, while 48.0% on female patients. Until the age of 49, the number of patients and their costs were higher for men, while those over the age of 50 were higher for women. CONCLUSION: Acute inpatient care was the major cost driver. The prevalence of the disease was by 26% higher in men compared to women. Orv Hetil. 2021; 162(Suppl 1): 54-60.

Cost and Treatment Characteristics of Sport-Related Knee Injuries Managed by Athletic Trainers: A Report From the Athletic Training Practice-Based Research Network.

CONTEXT: Knee injuries are common during sport participation. However, little is known about the overall management and estimated direct costs of care associated with these injuries when under the care of athletic trainers. OBJECTIVE: To describe the treatment characteristics and direct costs of care for athletic training services provided for patients with knee injuries. DESIGN: Descriptive study. SETTING: Ninety-five athletic training facilities across 24 states. PATIENTS OR OTHER PARTICIPANTS: A total of 117 athletic trainers (females = 56.4%, age = 29.4 ± 8.7 years, years certified = 4.7 ± 6.0, years employed at site = 1.6 ± 4.1). MAIN OUTCOME MEASURE(S): Complete patient cases were identified using International Classification of Disease-10 diagnostic codes between 2009 and 2020. Summary statistics were calculated for patient demographics, treatment characteristics, and direct costs of care. Treatment characteristics included the type of athletic training service, duration, amount (eg, number of visits), and direct costs of care. RESULTS: A total of 441 patient cases were included. The most common injuries reported were cruciate ligament sprain (18.1%, n = 80), medial collateral ligament sprain (15.4%, n = 68), and knee pain (14.1%, n = 62). Injuries occurred most frequently during football (35.4%, n = 156), basketball (14.7%, n = 65), and soccer (12.7%, n = 56). A total of 8484 athletic training services were recorded over 4254 visits, with therapeutic exercise (29.8%, n = 2530), hot or cold pack (25.8%, n = 2189), and therapeutic activities (11.2%, n = 954) being the most frequently reported services. The median duration of care was 23 days and number of visits was 8. The median total cost of care was $564 per injury and $73 per visit. CONCLUSIONS: Patients with knee injuries demonstrated greater time loss than those with other lower extremity injuries. Thus, it is unsurprising that knee injuries were associated with a longer duration and higher cost of care than other lower extremity injuries such as ankle sprains. Future researchers should examine the effectiveness of common treatment strategies and aim to identify treatments that can reduce costs and improve patient outcomes.

Costs resulting from nonprofessional soccer injuries in Switzerland: A detailed analysis.

BACKGROUND: Soccer injuries constitute an important public health problem and cause a high economic burden. Nevertheless, comprehensive data regarding injury costs in nonprofessional soccer are missing. The aim of this study was to determine which groups of nonprofessional soccer athletes, injury types, and injury situations caused high injury costs. METHODS: A cross-sectional, retrospective telephone survey was carried out with a random sample of persons who had sustained a soccer injury between July 2013 and June 2014 and who had reported this accident to the Swiss National Accident Insurance Fund (Suva). One year after the corresponding accident, every injury was linked to its costs and to the answers obtained in the interview about injury setting, injury characteristics, and injury causes. Finally, the costs of 702 injuries were analyzed. RESULTS: The average cost of an injury in nonprofessional soccer amounted to €4030 (bias-corrected and accelerated 95% confidence interval (BCa 95%CI): 3427-4719). Persons aged 30 years and older experienced 35% of soccer injuries but accounted for 49% of all costs. A total of 58% of all costs were the result of injuries that occurred during amateur games. In particular, game injuries sustained by players in separate leagues for players aged 30+/40+ years led to high average costs of €8190 (BCa 95%CI: 5036-11,645). Knee injuries accounted for 25% of all injuries and were responsible for 53% of all costs. Although contact and foul play did not lead to above-average costs, twisting or turning situations were highly cost relevant, leading to an average sum of €7710 (BCa 95%CI: 5376-10,466) per injury. CONCLUSION: Nonprofessional soccer players aged 30 years and older and particularly players in 30+/40+ leagues had above-average injury costs. Furthermore, the prevention of knee injuries, noncontact and nonfoul play injuries, and injuries caused by twisting and turning should be of highest priority in decreasing health care costs.

The Cost Variability of Orthobiologics.

BACKGROUND: Mixed results exist regarding the benefit of orthobiologic injections. The purpose of this study was to assess the variability in costs for platelet-rich plasma (PRP) and stem cell (SC) injections and evaluate for variables that influence pricing. HYPOTHESIS: There will be significant variability in the cost of PRP and SC injections throughout the United States. STUDY DESIGN: Descriptive epidemiology study. LEVEL OF EVIDENCE: Level 3. METHODS: Calls were made to 1345 orthopaedic sports medicine practices across the United States inquiring into the availability of PRP or SC knee injections and associated costs. In addition to pricing, the practice type, number of providers, and population and income demographics were recorded. Univariate statistical analyses were used to identify differences in availability and cost between variables. RESULTS: Of the contacted offices that provided information on both PRP and SC availability (n = 1325), 268 (20.2%) offered both treatments, 550 (41.5%) offered only PRP injections, 20 (1.5%) offered only SC injections, and 487 (36.8%) did not offer either treatment. The mean ± SD cost of a PRP injection was $707 ± $388 (range, $175-$4973), and the mean cost of an SC injection was $2728 ± $1584 (range, $300-$12,000). Practices offering PRP and SC injections tended to be larger (PRP, 12.0 physicians per practice vs. 8.1 [P < 0.001]; SC, 13.6 vs 9.7 [P < 0.001]). Practices that offered PRP injections were located in areas with higher median household income (P = 0.047). Variables associated with higher cost of PRP injections included city population (P < 0.001) and median income of residents (P < 0.001). CONCLUSION: While the majority of sports medicine practices across the United States offer some type of orthobiologic injection, there exists significant variability in the cost of these injections. CLINICAL RELEVANCE: This study demonstrates the significant variability in costs of orthobiologic injections throughout the country, which will allow sports medicine physicians to appreciate the value of these injections when counseling patients on available treatment options.

Cost-Effectiveness Analysis of Needle Arthroscopy Versus Magnetic Resonance Imaging in the Diagnosis and Treatment of Meniscal Tears of the Knee.

PURPOSE: To determine whether needle arthroscopy (NA) compared with magnetic resonance imaging (MRI) in the diagnosis and treatment of meniscal tears is cost-effective when evaluated over a 2-year period via patient-reported outcomes. The hypothesis is that improved diagnostic accuracy with NA would lead to less costly care and similar outcomes. METHODS: A Markov model/decision tree analysis was performed using TreeAge Pro 2017 software. Patients were evaluated for degenerative and traumatic damage to the lateral/medial meniscus. Assumed sensitivities and specificities were derived from the medical literature. The direct costs for care were derived from the 2017 Medicare fee schedule and from private payer reimbursement rates. Costs for care included procedures performed for false-positive findings and for care for false-negative findings. Effectiveness was examined using the global knee injury and osteoarthritis outcome score (KOOS). Patients were evaluated over 2 years for costs and outcomes, including complications. Dominance and incremental cost-effectiveness were evaluated, and 1- to 2-way sensitivity analysis was performed to determine those variables that had the greatest effect. The consolidated economics evaluation and reporting standards checklist for reporting economic evaluations was used. RESULTS: NA was less costly and had similar KOOS versus MRI for both the medial/lateral meniscus with private pay. Costs were less for both Medicare and private pay for medial meniscus, $780 to $1,862, and lateral meniscus, $314 to $1,256, respectively. CONCLUSIONS: Based on the reported MRI incidence of false positives with the medial meniscus and false negatives with the lateral meniscus and based on assumed standards of care, more costly care is provided when using MRI compared with NA. Outcomes were similar with NA compared with MRI. LEVEL OF EVIDENCE: Level II, economic and decision analysis.

Targeted rapid knee MRI exam using T2 shuffling.

BACKGROUND: MRI is commonly used to evaluate pediatric musculoskeletal pathologies, but same-day/near-term scheduling and short exams remain challenges. PURPOSE: To investigate the feasibility of a targeted rapid pediatric knee MRI exam, with the goal of reducing cost and enabling same-day MRI access. STUDY TYPE: A cost effectiveness study done prospectively. SUBJECTS: Forty-seven pediatric patients. FIELD STRENGTH/SEQUENCE: 3T. The 10-minute protocol was based on T2 Shuffling, a four-dimensional acquisition and reconstruction of images with variable T2 contrast, and a T1 2D fast spin-echo (FSE) sequence. A distributed, compressed sensing-based reconstruction was implemented on a four-node high-performance compute cluster and integrated into the clinical workflow. ASSESSMENT: In an Institutional Review Board-approved study with informed consent/assent, we implemented a targeted pediatric knee MRI exam for assessing pediatric knee pain. Pediatric patients were subselected for the exam based on insurance plan and clinical indication. Over a 2-year period, 47 subjects were recruited for the study and 49 MRIs were ordered. Date and time information was recorded for MRI referral, registration, and completion. Image quality was assessed from 0 (nondiagnostic) to 5 (outstanding) by two readers, and consensus was subsequently reached. STATISTICAL TESTS: A Wilcoxon rank-sum test assessed the null hypothesis that the targeted exam times compared with conventional knee exam times were unchanged. RESULTS: Of the 49 cases, 20 were completed on the same day as exam referral. Median time from registration to exam completion was 18.7 minutes. Median reconstruction time for T2 Shuffling was reduced from 18.9 minutes to 95 seconds using the distributed implementation. Technical fees charged for the targeted exam were one-third that of the routine clinical knee exam. No subject had to return for additional imaging. DATA CONCLUSION: The targeted knee MRI exam is feasible and reduces the imaging time, cost, and barrier to same-day MRI access for pediatric patients. LEVEL OF EVIDENCE: 2 Technical Efficacy: Stage 6 J. Magn. Reson. Imaging 2019.

Usefulness of a job-exposure matrix 'MADE' as a decision tool for compensation of work-related musculoskeletal disorders.

We aimed to assess the predictivity of the biomechanical job-exposure matrix 'MADE' using compensation data from the National Health Insurance for work-related disorders. Data were obtained from 2013 to 2015, area under curves (AUC), sensitivity, specificity and predictive values were calculated using compensation results as reference. We collected 163 128 cases data. AUC ranged from 0.64 for shoulders disorder to 0.82 for knee disorders. If two thresholds were considered, 28.7% of the sample fit under or over those. The matrix showed a fair predictivity. Such matrix cannot replace expertise but might be a tool used for improving compensation process.

Female rugby union injuries in New Zealand: A review of five years (2013-2017) of Accident Compensation Corporation moderate to severe claims and costs.

OBJECTIVES: To provide epidemiological data and related costs for moderate-to-serious and serious injury claims for women's rugby union in New Zealand. DESIGN: A retrospective analytical review of injury entitlement claims for women's rugby from 2013 to 2017. METHODS: Data were analysed by year of competition, age, body site and injury type for total and moderate-to-severe (MSC) Accident Compensation Corporation (ACC) claims and costs. RESULTS: Over 2013 to 2017 there were 26,070 total claims for female rugby union costing $18,440,812 [AD$16,956,998]. The 15-19-year age group recorded 40% (n=1,009) of the total female rugby union Moderate-to-serious and serious (MSC) claims and 41% ($5,419,157 [AD$4,983,112]) of the total female rugby union MSC costs. The knee was the most commonly recorded injury site accounting for 40.3% (n=1,007) of MSC claims and 46.9% ($6,229,714 [AD$5,728732]) of MSC costs with an average cost of $1,245,943 ±$217,796 [AD$595,351 ±AD$104,070] per-year for female rugby union. CONCLUSIONS: This is the first study to report the nature and related costs for moderate-to-serious and serious injury claims for women's rugby union in New Zealand. A total of 26,070 injury claims were lodged over the duration of the study but only 9.6% (n=2,501) of these were classified as MSC injury entitlement claims. Participants 25 years and older accounted for 31% of the female rugby union player claims. Females in the over 35-year age groups compete against younger participants which may account for the higher mean cost per-claim seen as the age groups increase in years until they retire from the game.

Microfracture is more cost-effective than autologous chondrocyte implantation: a review of level 1 and level 2 studies with 5 year follow-up.

PURPOSE: Focal cartilage defects in the knee may have devastating effect on the knee joint, where two of the main surgical treatment options are microfracture and autologous chondrocyte implantation. Comparative studies have failed to establish which method yields the best clinical results. A cost-effectiveness analysis of microfracture and autologous chondrocyte implantation would contribute to the clinical decision process. METHODS: A PubMed search identifying level I and level II studies with 5 year follow-up was performed. With the data from these studies, decision trees with associated service provision and costs connected to the two different techniques were designed. In addition to hospital costs, we included costs connected to physiotherapy following surgery. To paint a broader cost picture, we also included indirect costs to the society due to productivity loss caused by work absence. RESULTS: Four high-quality studies, with a follow-up of 5 years, met the inclusion criteria. A total of 319 patients were included, 170 undergoing microfracture and 149 autologous chondrocyte implantation. The re-operation rate was 23 (13.5%) following microfracture, and 18 (12.1%) for autologous chondrocyte implantation. Both groups achieved substantially better clinical scores at 5 years compared to baseline. Microfracture was more cost-effective when comparing all clinical scores. CONCLUSION: Microfracture is associated with both lower costs and lower cost per point increase in patient reported outcome measures. There is a need of well-designed, high-quality randomized controlled trials before reliable conclusions regarding cost-effectiveness in the long run is possible. LEVEL OF EVIDENCE: III.

Surgical reconstruction is a cost-efficient treatment option for isolated PCL injuries.

PURPOSE AND HYPOTHESIS: The main purpose of the study is to put focus on the costs related to treating posterior cruciate ligament (PCL) injuries and the possible implications of chosen treatment strategy to the respective institutions and society. METHODS: Costs of treating PCL injuries nonoperatively and for both single-bundle (SB) and double-bundle (DB) reconstruction were estimated. These costs were translated into equivalent quality-adjusted life years (QALY) given a threshold value of Euro (€) 70,000 per QALY. Expected gain in knee osteoarthritis outcome score (KOOS) quality of life (QoL) following surgery based on KOOS data from 112 patients was used as a basis for calculating the cost efficiency ratio. RESULTS: The average calculated cost of nonoperative treatment was €3382. Incremental cost for SB PCLR was €8585 (154%) and another increment of €5220 (61%) for DB PCLR using numbers from a European hospital. This is equivalent to increments of 0.074 (SB) and another 0.075 (DB) QALYs given the €70,000 threshold. For DB to be as cost efficient as SB reconstruction, the incremental gain in KOOS QoL has to be at the same level as for SB reconstruction compared to nonoperative treatment. CONCLUSION: Though surgical reconstruction adds a substantial cost to nonoperative treatment alone, it can be considered cost-effective. Double-bundle reconstruction is less cost efficient than SB reconstruction, but should probably still be considered the treatment of choice for certain patient categories. Randomized controlled trials looking at outcome following nonoperative, SB and DB PCL reconstruction are needed. The clinical relevance of this is that surgical reconstruction of PCL injuries is a cost-efficient treatment alternative in patients with an isolated PCL injury. This finding should be taken into consideration when deciding on how to treat these injuries. LEVEL OF EVIDENCE: III.

Preoperative Diagnosis Can Predict Conversion Total Knee Arthroplasty Outcomes.

BACKGROUND: Compared to total knee arthroplasty (TKA) for primary osteoarthritis, conversion TKAs in the post-traumatic setting are associated with increased operative times, infection rates, and readmissions. We aim at determining how post-traumatic osteoarthritis and previous knee surgery influence postoperative outcomes in conversion TKA. METHODS: Seventy-two conversion TKA procedures with prior knee trauma at a single institution between April 2012 and 2016 were examined. Twenty-seven (37.5%) cases had a preoperative site-specific diagnosis such as fracture of the proximal tibia, distal femur, or patella whereas 45 (62.5%) cases had a preoperative diagnosis of significant soft-tissue trauma. These 2 groups were compared in terms of total implant cost, length of stay, complications, and readmission and reoperation rates. A subanalysis was conducted to evaluate the effects of previous knee surgery on surgical outcomes. RESULTS: The postfracture TKA cohort suffered significantly higher early surgical site complications (22% vs 4.4%, P = .02) and 90-day readmissions (14.8% vs 2.2%, P = .042) compared to the soft-tissue trauma cohort. Operative time, total implant costs, length of stay, medical complications, 30-day readmissions, and 90-day reoperation rates did not significantly differ. It was also found that patients with multiple prior knee surgeries compared to one prior knee surgery are younger (53.0 vs 63.1, P = .003), healthier, and receive significantly more expensive implants (1.72 vs 1.07, P = .026). In addition, patients with previous open reduction internal fixations experience more surgical site complications than patients with previous arthroscopies (31% vs 3.3%, P = .042). CONCLUSION: Patients with previous site-specific fracture are more likely to experience surgical site complications and 90-day readmissions after conversion TKA than patients with previous soft-tissue knee trauma. Multiple previous knee surgeries appear to serve as an independent factor in the selection of costlier implants irrespective of preoperative diagnosis.

Analysis of medical service use of knee osteoarthritis and knee meniscal and ligament injuries in Korea: a cross-sectional study of national patient sample data.

BACKGROUND: Osteoarthritis (OA) and meniscal and ligament injuries of the knee are the two most common knee disorders in Korea. The aim of this study was to analyze the demographic characteristics, medical service use and related costs for these disorders, and the results are expected to help inform practitioners, researchers, and policy-makers. METHODS: The present study aimed to evaluate incidence and patient characteristics, and to assess current medical service use, usual care, and medical expenses of knee disorders by analyzing 2014 national patient sample data from the Korean Health Insurance Review and Assessment Service. Data was extracted using 3% stratified sampling from all Korea national health insurance claims submitted in 2014, and analyzed. Usual care for M17 knee osteoarthritis and S83 knee meniscal and ligament injury codes of the International Classification of Diseases, 10th revision (ICD-10) were determined by investigating total number of patients, sociodemographic characteristics, days in care, number of visits, and expenses. RESULTS: Knee OA showed the highest incidence in females aged ≥60 years, whereas meniscal and ligament injuries of the knee were most prevalent among patients aged <20 years and young adults. Total inpatient care expenses exceeded the cost of ambulatory care for both disorders. Ambulatory care was mainly provided at primary care clinics, with 90% of these visits made to orthopedic specialists. Medical expenses for knee OA and meniscal and ligament injuries were largely due to procedures/surgeries and injections, and procedures/surgeries and hospitalizations, respectively. Total replacement arthroplasty was the most commonly performed surgery for knee OA, while meniscectomy and cruciate ligament reconstruction were the most often performed surgeries for meniscal and ligament injuries. Intra-articular injection rates were 55% in knee OA patients and 3% in meniscal and ligament injury patients. Aceclofenac, diclofenac, and tramadol were the most frequently prescribed analgesics. CONCLUSIONS: The current findings may be used as basic data for establishing medical policies and can benefit researchers and clinicians in recognizing trends and patterns of treatment for knee disorders.

Chondral Injuries and Irreparable Meniscal Tears Among Adolescents With Anterior Cruciate Ligament or Meniscal Tears Are More Common in Patients With Public Insurance.

BACKGROUND: Access to health care services is a critical component of health care reform and may differ among patients with different types of insurance. Hypothesis/Purpose: The purpose was to compare adolescents with private and public insurance undergoing surgery for anterior cruciate ligament (ACL) and/or meniscal tears. We hypothesized that patients with public insurance would have a delayed presentation from the time of injury and therefore would have a higher incidence of chondral injuries and irreparable meniscal tears and lower preoperative International Knee Documentation Committee (IKDC) scores than patients with private insurance. STUDY DESIGN: Cross-sectional study; Level of evidence, 3. METHODS: This was a retrospective study of patients under 21 years of age undergoing ACL reconstruction and/or meniscal repair or debridement from January 2013 to March 2016 at a single pediatric sports medicine center. Patients were identified by a search of Current Procedural Terminology (CPT) codes. A chart review was performed for insurance type; preoperative diagnosis; date of injury, initial office visit, and surgery; preoperative IKDC score; intraoperative findings; and procedures. RESULTS: The study group consisted of 119 patients (mean age, 15.0 ± 1.7 years). Forty-one percent of patients had private insurance, while 59% had public insurance. There were 27 patients with isolated meniscal tears, 59 with combined meniscal and ACL tears, and 33 with isolated ACL tears. The mean time from injury to presentation was 56 days (range, 0-457 days) in patients with private insurance and 136 days (range, 0-1120 days) in patients with public insurance ( P = .02). Surgery occurred, on average, 35 days after the initial office visit in both groups. The mean preoperative IKDC score was 53 in both groups. Patients with meniscal tears with public insurance were more likely to require meniscal debridement than patients with private insurance (risk ratio [RR], 2.3; 95% CI, 1.7-3.1; P = .02). Patients with public insurance were more likely to have chondral injuries of grade 2 or higher (RR, 4.4; 95% CI, 3.9-5.0; P = .02). CONCLUSION: In adolescent patients with ACL or meniscal tears, patients with public insurance had a more delayed presentation than those with private insurance. They also tended to have more moderate-to-severe chondral injuries and meniscal tears, if present, that required debridement rather than repair. More rapid access to care might improve the prognosis of young patients with ACL and meniscal injuries with public insurance.

Injuries in Swedish floorball: a cost analysis.

The epidemiology of sport injuries is well documented. However, the costs are rarely discussed. Previous studies have presented such costs in specific sports or localization. No study has investigated the costs related to injuries in elite floorball. Thus, the aim of this study was to estimate cost of injuries in Swedish elite floorball players. During 1 year, 346 floorball players were prospectively followed. All time-loss injures were recorded. The injured players were asked to complete a questionnaire regarding their costs tied to the injury. Mean costs were calculated by multiplying the total resource use with the collected unit costs and dividing these total costs with the number of injuries as well as players. The results showed that the average cost per injury increased with the level of severity and ranged from 332 to 2358 Euros. The mild and moderate overuse injuries were costlier than the corresponding traumatic injuries. However, the severe traumatic injuries were associated with higher costs than overuse injuries. Knee injuries were the costliest. Our results indicate that there are costs to be saved, if floorball injuries can be avoided. They should be of interest to decision makers deciding whether to invest in preventive interventions.

Cost-effectiveness of Early Surgery versus Conservative Treatment with Optional Delayed Meniscectomy for Patients over 45†years with non-obstructive meniscal tears (ESCAPE study): protocol of a randomised controlled trial.

INTRODUCTION: Recent studies show similar outcome between surgery and conservative treatment in patients with non-obstructive meniscal tears. However, surgery is still often preferred over conservative treatment. When conservative treatment is non-inferior to surgery, shifting the current standard treatment choice to conservative treatment alone could save over €30 millions of direct medical costs on an annual basis. Economic evaluation studies comparing surgery to conservative treatment are lacking. METHODS AND ANALYSIS: A multicentre randomised controlled trial (RCT) with an economic evaluation alongside was performed to assess the (cost)-effectiveness of surgery and conservative treatment for meniscal tears. We will include 402 participants between 45 and 70 years with an MRI-confirmed symptomatic, non-obstructive meniscal tears to prove non-inferiority of conservative treatment. Block randomisation will be web-based. The primary outcome measure is a physical function, measured by the International Knee Documentation Committee 'Subjective Knee Form'. Furthermore, we will perform a cost-effectiveness and cost-utility analysis from societal perspective and a budget impact analysis from a societal, government and insurer perspective. Secondary outcomes include general health, quality of life, activity level, knee pain, physical examination, progression of osteoarthritis and the occurrence of adverse events. ETHICS AND DISSEMINATION: This RCT will be performed in accordance with the Declaration of Helsinki and has been approved by the Ethics Committee (number NL44188.100.13). The results of this study will be reported in peer-reviewed journals and at international conferences. We further aim to disseminate our results to guideline committees. TRIAL REGISTRATION NUMBER: NCT01850719.

The cost and distribution of firefighter injuries in a large Canadian Fire Department.

BACKGROUND: There is limited data available regarding the cost of firefighter injuries. This information is necessary to develop targeted injury prevention strategies. OBJECTIVE: To categorize the cost of injuries filed in 2012 by firefighters from a from a large department by job duty, injury type, body part affected, and the general motion pattern employed at the time of injury. METHODS: Data were taken from reports filed by CFD personnel and claims filed with the Workers' Compensation Board (WCB) of Alberta between January 1, 2012 and December 31, 2012. RESULTS: Of the 244 injuries reported, 65% were categorized as sprains and strains, the most frequent of which affected the back (32%). The total cost of all claims was $555,955; 77% were sprain/strain-related. Knee and back injuries were most costly ($157,383 and $100,459). Categorized by job duty, most sprains/strains (31%) were sustained while attending to fire station responsibilities, although physical training was associated with the highest costs (34%). Fireground operations were attributed to 18% of sprains/strains and 16% of costs. Lifting injuries were more frequent (23%) and costly (20%) than all injuries. CONCLUSIONS: The most common and costly injuries occurred while attending to fire station-related responsibilities and during physical training.

No economic benefit of early knee reconstruction over optional delayed reconstruction for ACL tears: registry enriched randomised controlled trial data.

BACKGROUND: To analyse 5-year cost-effectiveness of early versus optional delayed acute anterior cruciate ligament (ACL) reconstruction. METHODS: 121 young, active adults with acute ACL injury to a previously uninjured knee were randomised to early ACL reconstruction (n=62, within 10 weeks of injury) or optional delayed ACL reconstruction (n=59; 30 with ACL reconstruction within 6-55 months); all patients received similar structured rehabilitation. Real life data on health care utilisation and sick leave were obtained from regional and national registers. Costs and quality-adjusted life years (QALYs) were discounted at 3%. Full-analysis set (based on study randomisation) and as-treated analysis (according to actual treatment over 5 years) principles were applied. RESULTS: Mean cost of early ACL reconstruction was €4695 higher than optional delayed ACL reconstruction (p=0.19) and provided an additional 0.13 QALYs (p=0.11). Full-analysis set showed incremental net benefit of early versus optional delayed ACL reconstruction was not statistically significantly different from zero at any level. As-treated analysis showed that costs for rehabilitation alone were €13 650 less than early ACL reconstruction (p<0.001). Results were robust to sensitivity analyses. CONCLUSIONS: In young active adults with acute ACL injury, a strategy of early ACL reconstruction did not provide extra economic value over a strategy of optional delayed ACL reconstruction over a 5-year period. Results from this and previous reports of the KANON-trial imply that early identification of individuals who would benefit from either early ACL reconstruction or rehabilitation alone might reduce resource consumption and decrease risk of unnecessary overtreatment.

Characteristics of inpatient anterior cruciate ligament reconstructions and concomitant injuries.

PURPOSE: The purpose of this epidemiologic study was to quantify the incidence, expense, and concomitant injuries for anterior cruciate ligament reconstruction (ACLR) procedures in the USA from 2003 to 2011 that required an inpatient stay. It was hypothesized that the relative reported rates of concomitant knee injuries would be greater with the MCL and menisci compared to all other concomitant knee injuries. METHODS: The National Inpatient Sample from 2003 to 2011 was retrospectively sampled using ICD-9-CM codes to identify ACLR patients and to extrapolate national averages. RESULTS: Between the years of 2003-2011, an average of 9,037 ± 1,728 inpatient hospitalization included ACLRs, of which 4,252 ± 1,824 were primarily due to the ACLR. Inpatient visits primarily due to ACLR involved an average hospitalization of 1.7 ± 0.2 days and cost $30,118 ± 9,066 per patient. Knee injuries that were commonly reported along with inpatient ACLRs included medial meniscus damage (18.1 %), lateral meniscus damage (16.8 %), collateral ligament repairs (12.3 %), and medial collateral ligament strains (6.9 %). Prevalence of meniscus injuries was consistent across years, but MCL-related injuries increased over time. CONCLUSIONS: ACLR-related inpatient hospitalizations account for approximately 7.1 % of the total ACLRs performed annually in the USA. Inpatient ACLR procedures continue to decrease in frequency; however, the mean cost per patient increased. Meniscus and collateral ligament injuries were the most commonly reported concomitant knee injuries. The clinical relevance of this investigation is that it informs, on a large clinical cohort of patients, the current state of incidence and expense for ACLR surgeries in an inpatient setting.

Effectiveness of neuromuscular electrical stimulation in the functional knee rehabilitation in soldiers / Eficacia de la estimulación eléctrica neuromuscular en la rehabilitación funcional de rodilla en soldados

BACKGROUND: The versatility of military physical therapist practice enables them not only to diagnose knee injuries but also to provide a wide range of definitive care and rehabilitation, reducing the need for costly evacuation. The aim this study was to evaluate the effectiveness of interventions by Neuromuscular Electrical Stimulation (NMES) in the functional knee rehabilitation in soldiers and describe the main predictors and determinants in each intervention. METHODS: A systematic search of the literature about NMES in physiotherapy was performed using the following electronic databases: Web of Science, PubMed, Cochrane, Physiotherapy Evidence Database (PEDro) and CINAHL. The search strategy was: 'neuromuscular electrical stimulation' and 'physical therapy' and 'strengthening' and 'knee'. Inclusion criteria were: original articles published and peer reviewed between 2004-2015, focusing on physiotherapy interventions by NMES on subjects older than 18 years. A total resulting from 46 studies was included in the study. RESULTS: The results show the evidence on the effectiveness of NMES therapeutic/preventive purposes in the muscular system; and the importance of physical therapy in the army. CONCLUSION: As a method of functional knee rehabilitation, NMES proves effective in achieving the therapeutic/preventive objectives in soldiers. Level of Evidence: II.

Microfracture and osteochondral autograft transplantation are cost-effective treatments for articular cartilage lesions of the distal femur.

BACKGROUND: Multiple techniques have been suggested for the treatment of isolated knee articular cartilage injuries. For smaller lesions (<2-5 cm(2)), microfracture and osteochondral autograft transplantation (OAT) are commonly used options. With an increasing focus on health care efficiency, analyzing the cost-effectiveness of treatment modalities has become increasingly important. PURPOSE/HYPOTHESIS: The purpose of this study was to analyze the costs and outcomes of microfracture and OAT to compare their cost-effectiveness. The hypothesis was that microfracture would be more cost-effective. STUDY DESIGN: Economic and decision analysis; Level of evidence, 2. METHODS: A literature search was performed to identify studies comparing microfracture and OAT for the treatment of articular cartilage lesions of the distal femur in an adult population. Data from these studies including surgical time, failure rates, revision surgeries, outcome scores, and return to athletics were then incorporated into a constructed cost model using standard accounting methodology. The model was based on actual 2013 cost figures (in US dollars) for all procedure, operating room, and instrumentation costs. RESULTS: Three studies, with a mean follow-up of 8.7 years, met the inclusion criteria of having evidence level 1 or 2 comparing microfracture and OAT. There was a cumulative 28.6% reoperation rate among patients undergoing microfracture compared with 12.5% among patients undergoing OAT. While both groups demonstrated significant improvements compared with preoperative levels, the only significant differences in any outcome score reported between the 2 procedures were the International Cartilage Repair Society (ICRS) score and patient-reported return to their previous sports activity level. While microfracture had a lower initial cost ($3100), these savings lessened over 1 year ($1843) and 10 years ($996). Microfracture was more cost-effective when comparing Lysholm and Hospital for Special Surgery scores, whereas OAT was more cost-effective when comparing Tegner and ICRS scores. There was a significantly lower cost for return to play in athletes after OAT versus microfracture at 1 year ($11,428 vs $16,953, respectively), 3 years ($12,856 vs $38,000, respectively), and 10 years ($32,141 vs $60,799, respectively). CONCLUSION: Published level 1 and 2 clinical studies with a 10-year follow-up demonstrated that the net cost and cost-effectiveness of microfracture and OAT are comparable for the treatment of isolated articular cartilage lesions of the distal femur. CLINICAL RELEVANCE: Given similar clinical outcomes, microfracture and OAT are both viable, cost-effective first-line treatment options for these injuries.
