    AIM: To compare the efficacy of 7-d versus 14-d triple therapy for the treatment of H pylori infection in Chile, with a prevalence of 73% in general population. METHODS: H pylori-infected patients diagnosed by rapid urease test, with non-ulcer dyspepsia or peptic ulcer disease were randomized to receive omeprazole 20 mg bid, amoxicillin 1 g bid, and clarithromycin 500 mg bid for 7 (OAC7) or 14 (OAC14) d. Primary outcome was eradication rate 6 wk after the treatment. Subgroup analysis was carried out considering the eradication rate among patients with or without peptic ulcer disease and eradication rate among smokers or non-smokers.

    "Residents get no ... satisfaction" a problem to face during internal medicine rotations: development and psychometric properties of the IMPRINT-15

    Clinical rotations are an essential part of Internal Medicine (IM) residency programmes, where curricular objectives are carried out. To our knowledge, there are no validated instruments to assess IM clinical rotations. Our objective was to develop an instrument for residents to assess the quality of clinical rotations in an IM residency programme, and to test the psychometric properties of the instrument. A mixed methodology was used, including qualitative and quantitative phases. Items were proposed by a group of experts based on previously identified residency needs, followed by a quantitative phase to generate consensus among educators and residents to define which items would be included in the instrument (Delphi panel). After generating the instrument, psychometric tests were performed to assess construct validity (factor analysis) and reliability (Raykov's reliability coefficient). We obtained a 15-item instrument after two Delphi rounds: Internal Medicine Program Instrument 15-items (IMPRINT-15). Sixty-two residents answered 428 surveys using a Likert scale during 7 months (response rate 98.9%). The median score was 4.3 (IQR 3.9-4.7) (scale from 1 to 5). The factor analysis showed two domains in the clinical rotation assessment: (1) teaching and care activities; (2) evaluation and feedback. The instrument is reliable with Raykov's reliability coefficient of 0.86. Also, Raykov's reliability coefficient for the domains were 0.89 and 0.83, respectively. The IMPRINT-15 instrument is a bi-dimensional, valid and reliable questionnaire to evaluate the perceived quality by residents of the IM clinical rotations. Also, it constitutes the first validated instrument in this field worldwide.
