Abstract: Disclosed embodiments include computer-implemented methods and systems that can efficiently generate highly relevant recommended search terms to clinicians. A hybrid collaborative filtering model recommends search terms for a specific patient to the clinician. The model draws on information from patients' clinical encounters and the searches that were performed during the clinical encounters. To generate recommendations, the model uses search terms which are (1) frequently co-occurring with the ICD codes recorded for the patient and (2) highly relevant to the most recent search terms. One variation of the model uses only the most recent ICD codes assigned to the patient. Another variation uses all ICD codes. Comprehensive experiments of embodiments of the methods and systems have demonstrate high levels of performance.

Abstract: The present invention belongs to the technical field of biological medicine, and specifically relates to use of sodium formate in preparation of an anti-infective drug. The present invention has found through research that sodium formate can significantly increase the sensitivity of a bacterium to an antibiotic, so that the antibiotic that is originally ineffective or inefficient against a pathogenic bacterium becomes effective or efficient, thereby killing the bacterium and achieving an anti-infective effect. Sodium formate and an antibiotic are further prepared into an anti-infective composition, so that on the one hand, a significant anti-infective effect can be achieved under the condition of a low-concentration antibiotic, and on the other hand, the decreased use amount of the antibiotic can also significantly reduce the likelihood of a bacterium developing drug resistance; and sodium formate has been widely used in food and medicine with high safety.
