RESUMO
OBJECTIVES: Documentation of allergies in a coded, non-free-text format in the electronic health record (EHR) triggers clinical decision support to prevent adverse events. Health system-wide patient safety initiatives to improve EHR allergy documentation by specifically decreasing free-text allergy entries have not been reported. The goal of this initiative was to systematically reduce free-text allergen entries in the EHR allergy module. METHODS: We assessed free-text allergy entries in a commercial EHR used at a multihospital integrated health care system in the greater Boston area. Using both manual and automated methods, a multidisciplinary consensus group prioritized high-risk and frequently used free-text allergens for conversion to coded entries, added new allergen entries, and deleted duplicate allergen entries. Environmental allergies were moved to the patient problem list. RESULTS: We identified 242,330 free-text entries, which included a variety of environmental allergies (42%), food allergies (18%), contrast media allergies (13%), "no known allergy" (12%), drug allergies (2%), and "no contrast allergy" (2%). Most free-text entries were entered by medical assistants in ambulatory settings (34%) and registered nurses in perioperative settings (20%). We remediated a total of 52,206 free-text entries with automated methods and 79,578 free-text entries with manual methods. CONCLUSIONS: Through this multidisciplinary intervention, we identified and remediated 131,784 free-text entries in our EHR to improve clinical decision support and patient safety. Additional strategies are required to completely eliminate free-text allergy entry, and establish systematic, consistent, and safe guidelines for documenting allergies.

Confusion about patients' medication regimens during the hospital admission and discharge process accounts for many preventable and serious medication errors. Many organizations have begun to redesign their clinical processes to address this patient safety concern. Partners HealthCare, an integrated delivery network in Boston, Massachusetts, has answered this interdisciplinary challenge by leveraging its multiple outpatient electronic medical records (EMR) and inpatient computerized provider order entry (CPOE) systems to facilitate the process of medication reconciliation. This manuscript describes the design of a novel application and the associated services that aggregate medication data from EMR and CPOE systems so that clinicians can efficiently generate an accurate pre-admission medication list. Information collected with the use of this application subsequently supports the writing of admission and discharge orders by physicians, performance of admission assessment by nurses, and reconciliation of inpatient orders by pharmacists. Results from early pilot testing suggest that this new medication reconciliation process is well accepted by clinicians and has significant potential to prevent medication errors during transitions of care.

A 6-year-old girl required argatroban at dosages up to 18 mug/kg/minute for treatment of heparin-induced thrombocytopenia (HIT) type 2; however, her activated partial thromboplastin time (aPTT) values remained subtherapeutic. Treatment was converted to lepirudin, which resulted in therapeutic aPTT values, and later to long-term warfarin therapy; no further thromboembolic incidents occurred. The reporting of cases of HIT in prepubertal patients has generally been scarce. Argatroban and lepirudin dosing and pharmacokinetics have not yet been established for young children. The argatroban dosage for this patient exceeded the upper limit of the dose range for adults. Several possible explanations for why argatroban did not illustrate typical first-order pharmacokinetics in this patient are discussed, and the pharmacokinetics and pharmacodynamics of argatroban are compared with those of lepirudin, with special consideration given to the pediatric population.

Unintended medication discrepancies at hospital admission and discharge potentially harm patients. Explicit medication reconciliation (MR) can prevent unintended discrepancies among care settings and is mandated by JCAHO for 2005. Enterprise-wide, we are linking pre-admission and discharge medication lists in our outpatient electronic health records (EHR) with our inpatient order entry applications (OE) - currently not interoperable - to support MR and inform the development of comprehensive MR among hospitalized patients.

BACKGROUND: Argatroban is a direct thrombin inhibitor used to treat heparin-induced thrombocytopenia (HIT). Argatroban is primarily cleared by hepatic mechanisms, with only small amounts of unchanged drug cleared by the kidneys. OBJECTIVE: To assess the effects of renal function on argatroban dose and activated partial thromboplastin time (aPTT). METHODS: Patients treated with argatroban were identified and prospectively screened. Patients with liver dysfunction were excluded from the analysis. Charts and laboratory data were reviewed daily until a therapeutic aPTT was reached or argatroban was discontinued. Data points collected included age, weight, gender, admitting diagnosis, past medical history, indication for anticoagulation, indication for argatroban, initial dose, goal aPTT, titration instructions, liver function tests, serum creatinine (S(cr)), blood urea nitrogen, and estimated creatinine clearance (Cl(cr)). RESULTS: A total of 66 patients were evaluated and 44 met criteria for inclusion. Baseline S(cr) was elevated at 1.5 mg/dL (0.9, 2.3; median 25th, 75th percentile), with an estimated Cl(cr) 40 mL/min/1.73 m(2) (26, 74). The median dose of argatroban to reach the predefined therapeutic range was 1 microg/kg/min (0.68, 2), with a corresponding aPTT of 60 seconds (54, 66). After univariate analysis, Cl(cr) significantly predicted the therapeutic dose (coefficient b +/- SE 0.019 +/- 0.004; r(2) 0.35; p < 0.001). Covariates that predicted dose were the presence of HIT (coefficient b +/- SE -0.61 +/- 0.3; p = 0.045), history of myocardial infarction (coefficient b +/- SE -0.74 +/- 0.3; p = 0.02), and an indication for anticoagulation of deep-vein thrombosis/pulmonary embolism (coefficient b +/- SE 0.69 +/- 0.3; p = 0.03). CONCLUSIONS: Estimated Cl(cr) significantly predicted the dose of argatroban needed to reach a therapeutic aPTT.

A 49-year-old man with cirrhosis due to hepatitis C virus developed interstitial pneumonitis documented by surgical lung biopsy specimen evaluation after two weekly doses of pegylated interferon-alpha(2)b in combination with ribavirin. He developed ARDS and died after 26 days of hospitalization from multisystem organ failure. This case suggests that interstitial pulmonary disease can occur with pegylated interferon-alpha(2)b therapy.
