Purpose: To determine the prevalence, healthcare resource utilization and costs (HCRU&C) of knee osteoarthritis (OA) patients versus controls. Patients and Methods: Retrospective, matched-cohort administrative claims analysis using IBM MarketScan databases (2011)(2012)(2013)(2014)(2015)(2016)(2017). Newly diagnosed, adult (18+ yrs) knee OA patients identified by ICD9/10 code were matched 1:1 to controls by age, sex, payer, and geography; alpha level set to 0.05. Prevalence was estimated for 2017. All-cause and knee OA-related HCRU&C reported per-patient-per-year (PPPY) over follow-up period up to 4 years. Results: Overall 2017 knee OA prevalence was 4% (615,514 knee OA/15.4M adults). A total of 510,605 patients meeting inclusion criteria were matched 1:1 with controls. The knee OA cohort had mean age 60 years and was 58% female. Versus controls, knee OA patients had significantly more PPPY outpatient (84.5 versus 45.0) and pharmacy (29.8 versus 19.8
Aims: To assess the prevalence, health care resource utilization (HCRU), and economic burden of disease among Medicare beneficiaries with a principal diagnosis of osteoarthritis (OA) of the knee. Materials and methods: Patients with a principal diagnosis of knee OA were identified from the 5% noninstitutional sample file within 2009 and 2014 Medicare fee-for-service Limited Data Sets. A complete medical benefit record for each individual was generated by linking patient data across corresponding institutional claims from inpatient, outpatient, skilled nursing facility, and home health care services. The study revealed the prevalence and HCRU among Medicare knee OA patients, as well as the patient-level burden of disease by comparing HCRU and costs between knee OA patients and matched control patients. Results: The prevalence of principal diagnosis of knee OA among Medicare beneficiaries increased from 5.9% in 2009 to 6.2%
Patients with Crohn's disease were able to avoid new prescriptions for corticosteroids at a statistically higher rate when treated with an anti-TNF agent. These results demonstrate that the anti-TNF agents are superior to azathioprine for minimizing exposure to corticosteroids.
Background Empiric vancomycin treatment is frequently used in hemodialysis (HD) patients because of ease of administration when methicillin-resistant Staphylococcus aureus (MRSA) infection is suspected. Differing rates of MRSA indicate that empiric antibiotic treatment should be based on a center-specific antibiogram. Objective To develop a center-specific antibiogram, evaluate antibiotic prescribing patterns, and determine areas of improvement in infection treatment. Methods The antibiogram was constructed from culture and susceptibility (C&S) data from January through December 1999. Evaluation of prescribing habits was based on 3 criteria: (1) Hospital Infection Control Practices Advisory Committee and Centers for Disease Control and Prevention guidelines; (2) vancomycin for 1 dose followed by appropriate antibiotic based on C&S results; and (3) C&S obtained with more than 1 dose of antibiotic. Results HD was provided to 161 patients during the study period. Antibiotics were empirically prescribed 104 times in 62 different patients. Cultures were obtained 122 times, and 67 different isolates were identified. Gram-positive organisms and gram-negative organisms accounted for 77.6% and 22.4% of isolates, respectively. Gram-positive organisms were identified as Staphylococcus spp. (53.8%); 17.9% of the staphylococcal isolates were MRSA strains. No isolates of vancomycin-resistant enterococcus were identified. Based on the antibiogram, empiric antibiotic therapy within our center should be 1 dose each of vancomycin and an aminoglycoside. Empiric vancomycin was used 71 times. When criterion I is used, 12 prescriptions (16.9%) were considered appropriate. When criterion II and adjustment for MRSA reported for our center were used, 46 (64.8%) vancomycin prescriptions were considered appropriate. Forty-one patients had more than 1 dose of antibiotic therapy, and 18 (43.9%) of those patients did not have C&S data obtained as prescribed by criterion III. Areas of prescribing improvement include obtaining a C&S in all suspected infections prior to empiric therapy and a more aggressive antibiotic switch based on C&S results. Conclusions Antibiograms can be used to determine appropriate empric antibiotic therapy and identify areas of improvement.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
