RESUMO
BACKGROUND: Lean principles have been used at Denver Health Medical Center since 2005 to streamline nonclinical processes. Despite allocation of significant resources, particularly the expense of low molecular weight heparin (LMWH), to prophylaxis of venous thromboembolism (VTE), the incidence of postoperative VTE was significantly worse than national benchmarks. VTE risk factors were not consistently assessed, and the prescribing of prophylaxis varied widely. Lean was employed to standardize and implement risk assessment and evidence-based VTE prophylaxis for the institution. METHODS: In a rapid improvement event, a multidisciplinary group formulated an evidence-based risk assessment tool and clinical practice guideline for VTE prophylaxis, with plans for hospitalwide implementation and monitoring. RESULTS: The effects were immediate and improved steadily with feedback to clinicians. Within six months, compliance with the standard approached 100%. One year after implementation, the use of LMWH decreased more than 60% below baseline, and the use of sequential compression devices decreased by nearly 30%. With increased use of unfractionated heparin, the cost savings on VTE prophylaxis exceeded $15,000 per month, for a total of $425,000 since implementation. Moreover, the incidence of VTE decreased markedly during the same period. By reducing VTE rates, a total cost savings of $6.2 million was estimated for the past 28 months. CONCLUSIONS: Applying Lean to the clinical management of VTE prophylaxis improved compliance with standards and saved the hospital a significant amount of money. This was achieved without compromising clinical outcomes. This experience could be replicated at other institutions.

BACKGROUND: Clinical hospital medicine fellowships could accelerate the acquisition of increasingly demanding skills while enhancing esteem among subspecialty peers. We sought to determine whether medicine residents perceived such fellowships as relevant and would be willing to forgo substantial income during the training period, in the context of the perspectives of employers and practicing hospitalists. DESIGN: A series of 3 tandem nationwide cross-sectional surveys conducted over the Internet during late 2005 and early 2006. METHODS: Survey I was sent to 195 hospitalist employers identified through filtering classified advertisements. Survey II (containing Survey I results) was E-mailed by the Society of Hospital Medicine to its practicing hospitalists members. Survey III (containing results of the first 2 surveys) was E-mailed to U.S. internal medicine program directors for forwarding to their residents. RESULTS: Two-thirds of 103 employers would offer either a signing bonus or a starting salary increase of at least $10,000 to fellowship graduates (more than 20% would pay at least $20,000 more in the salary). Based on a median experience of 8 years, 91% of 101 practicing hospitalists believed that clinical fellowship could at least possibly be a favorable career move, with 58% recommending it as being a probably or strongly favorable career move. Of 279 categorical medicine residents, 44% were considering a hospital medicine career, of whom 57% would consider doing a year of clinical fellowship training if available. CONCLUSIONS: This study reveals a potentially unmet demand for clinical hospital medicine fellowship training. Further determination of need and related curricular development could be addressed under the leadership of national hospital medicine educational organizations.

OBJECTIVE: The purposes of this study were to apply near-real-time dose-measurement technology with metal oxide semiconductor field effect transistors (MOSFETs) to the assessment of organ dose during CT and to validate the method in comparison with the thermoluminescent dosimeter (TLD) method. MATERIALS AND METHODS: Dosimetry measurements were performed in two ways, one with TLDs and the other with MOSFETs. Twenty organ locations were selected in an adult anthropomorphic female phantom. High-sensitivity MOSFET dosimeters were used. For the reference standard, TLDs were placed in the same organ locations as the MOSFETs. Both MOSFET and TLD detectors were calibrated with an X-ray beam equivalent in quality to that of a commercial CT scanner (half-value layer, approximately 7 mm Al at 120 kVp). Organ dose was determined with a scan protocol for pulmonary embolus studies on a 4-MDCT scanner. RESULTS: Measurements for selected organ doses and the percentage difference for TLDs and MOSFETs, respectively, were as follows: thyroid (0.34 cGy, 0.31 cGy, -8%), middle lobe of lung (2.4 cGy, 3.0 cGy, +26%), bone marrow of thoracic spine (2.2 cGy, 2.5 cGy, +11%), stomach (1.0 cGy, 0.93 cGy, -6%), liver (2.5 cGy, 2.6 cGy, +6%), and left breast (3.0 cGy, 2.9 cGy, -1%). Bland-Altman analysis showed that the MOSFET results agreed with the TLD results (bias, 0.042). CONCLUSION: We found good agreement between the results with the MOSFET and TLD methods. Near-real-time CT organ dose assessment not previously feasible with TLDs was achieved with MOSFETs. MOSFET technology can be used for protocol development in the rapidly changing MDCT scanner environment, in which organ dose data are extremely limited.
