Background: Clinical documentation and information retrieval consume over half of physicians working hours, contributing to cognitive overload and burnout. While artificial intelligence offers a potential solution, concerns over hallucinations and source reliability have limited adoption at the point of care. This study aimed to evaluate physician-perceived time efficiency, decision-making support, and satisfaction with DR. INFO, an agentic AI clinical assistant, in routine clinical practice. Methodology: In this prospective, single-arm, pilot feasibility study, 29 physicians and medical students across multiple specialties in Portuguese healthcare institutions used DR. INFO v1.0 over five working days within a two-week period. Outcomes were assessed via daily Likert-scale evaluations (time saving and decision support) and a final Net Promoter Score (NPS). Non-parametric methods were used throughout, with bootstrap confidence intervals (CIs) and sensitivity analysis to address non-response. Results: Physicians reported high perceived time saving (mean = 4.27/5; 95% CI = 3.97-4.57) and decision support (mean = 4.16/5; 95% CI = 3.86-4.45), with ratings stable across the five-day study window. Among the 16 (55%) participants who completed the final evaluation, the NPS was 81.2, with no detractors; sensitivity analysis indicated an NPS of 44.8 under conservative non-response assumptions. Conclusions: Physicians across specialties and career stages reported positive perceptions of DR. INFO for both time efficiency and clinical decision support within the study window. These findings are preliminary and should be confirmed in larger, controlled studies that include objective performance measures and independent accuracy verification.

INFO在日常临床实践中提升医生感知的时间效率、决策支持能力及满意度。方法：在这项前瞻性、单臂、试点可行性研究中，来自葡萄牙医疗机构多个专科的29名医生和医学生在两周内连续五个工作日使用DR. INFO v1.0。通过每日李克特量表评估（时间节省与决策支持）及最终净推荐值（NPS）衡量结果。全程采用非参数方法，并引入自助法置信区间（CI）与敏感性分析处理无应答数据。结果：医生报告了较高的时间节省感知（均值=4.27/5；95% CI=3.97-4.57）与决策支持感知（均值=4.16/5；95% CI=3.86-4.45），评分在五天研究窗口期内保持稳定。在完成最终评估的16名（55%）参与者中，NPS为81.2，无贬低者；敏感性分析显示，在保守无应答假设下NPS为44.8。结论：研究窗口期内，各专科及职业阶段医生对DR. INFO在时间效率与临床决策支持方面的评价均为正面。这些发现属于初步结果，需在包含客观绩效指标及独立准确性验证的大规模对照研究中进一步确认。
