design, patient selection, and assignment to treatment, evaluation of outcome, analysis of data, interpretation of the results, and public dissemination of the information. In papers that pool existing data, bias may impact the articles that are available (publication bias), the process of selecting articles for inclusion, the assessment of outcomes, and the interpretation of the results. Evaluations of surgical procedures and devices are more susceptible to certain types of bias than medical studies. Peer reviewers may introduce personal bias into the review process

was set at $11,031, or when the incremental cost of AIC shunts was set at $1682 per device. External Ventricular Drains Six studies evaluating AIC versus non-AIC EVDs in the treatment of hydrocephalus were identified. Two of the 6 studies were RCTs in adults, 2 were prospective cohort studies in children, and 2 were prospective cohort studies in pediatric and adult patients combined. As was seen with shunt catheters, patients in the 2 treatment groups of the EVD studies were similar in terms of demographics, etiology of hydrocephalus, and the type of EVD

Low back–related outpatient visits (surgeons, chiropractor, other physicians, physical therapists, and/or acupuncturist), diagnostic tests (radiography, CT scanning, MR imaging, and electromyography), devices (braces, canes, and walkers), injections, emergency department visits, back-specific medications (NSAIDs, Cox-2 inhibitors, oral

All titles obtained from these search criteria were reviewed. Case reports, technical notes, single cohort series with no comparison of AIS versus non-AIS catheters, and animal or laboratory studies were discarded. Abstracts were then reviewed for all remaining clinical studies comparing AIS and non-AIS devices. Studies that compared the incidence of infection between AIS

device applications, automated calling services, or open patient-community web portals—is currently being discussed. Minimizing Bias and Confounding (Real-World Practice Setting, Avoiding Research Consent) The advantage of prospective registries over randomized controlled trials lies not only in their timeliness, feasibility, and cost-effectiveness with respect to patient enrollment and data collection, but in their true representativeness of real-world care. Efficacy in artificially controlled research settings may not be generalizable to community health care

clinicians participate in the routine collection, analysis, and application of clinical data related to the safety, quality, and value of care. Health Care Reform and the Emerging Requirement for Quality Data Over the past several decades, the biomedical community has successfully used scientific methodologies to fuel dramatic progress in the practice of medicine, to the benefit of patients and the groups that serve them, including physicians and biotechnology industry. Most of this progress has been related to the development of countless new devices and procedures

. Inclusion Criteria All patients undergoing 1- or 2-level PLIF or TLIF procedures between 2003 and 2009 were included in our analysis. These patients were identified through the presence of all of the following ICD-9-CM procedure codes: 81.08 (lumbar and lumbosacral fusion, posterior technique), 81.62 (fusion or refusion of 2–3 vertebrae), and 84.51 (insertion of interbody spinal fusion device). Open as opposed to MI techniques were distinguished by the use of pedicle screw system trade-name identifiers within the hospital charge data. Fusions were classified as MI if

The 2-year direct medical costs were estimated by multiplying medical resource use by unit costs based on current Medicare national allowable payment amounts. Surgeon costs were based on Medicare allowable amounts using the resource-based relative

retardation in children as well as meningitis, endocarditis, and prolonged hospitalization in adults. 37 , 47 , 48 The incidence of CSF shunt infection generally ranges from 3% to 15%, with the majority of infections occurring within the first 4 months after surgery. 4 , 11–13 , 16 , 33–35 Infection is most often secondary to colonization of the shunt device by nonpathogenic skin flora at the time of surgery, with approximately 90% of these infections caused by Staphylococcus species. 21 As early as the mid-1970s, in vitro and in vivo studies demonstrated that
