Framed as initial release, not as an update. --- ID Quick Reference is a bedside infectious disease reference for clinicians — supervised by Satoshi Kutsuna, MD, infectious disease specialist. Designed for internal medicine, hospital medicine, ED, pediatrics, primary care, and ID trainees, it organizes principles, organ-system syndromes, microbes, antimicrobials, infection prevention, vaccines, and clinical calculators across 7 parts. Anchored to current US guidelines (IDSA, CDC, ACIP, AHA, NIH) and select international sources (ESCMID, ESC, EUCAST, NICE) — citation dates and recommendation IDs are surfaced inline. 【Key features】 Antibiotic Spectrum Chart 36 antibiotics × 64 organisms at a glance. One tap from the top of Part 4 opens an interactive chart in 6 Gram-stain groups (Gram-positive cocci/rods, Gram-negative cocci/rods, anaerobes, other). Three-tier color shading — dark blue (typically active), light blue (limited), unshaded (generally not active) — makes coverage intuitive. Filter by 13 drug classes. Two-way navigation between the chart and each drug detail page. Clinical Antibiogram (subscriber feature) Photograph or upload your institution's antibiogram (PDF or image). AI (Anthropic Claude Vision via the developer-controlled backend) extracts pathogen × antibiotic susceptibility data into a structured table. Multi-image upload supported (up to 5). Each disease chapter's empiric therapy view overlays your institution's data alongside guideline-based recommendations. Built for iPhone and iPad Universal build. Left side-rail navigation on iPad, full-width tables, centered floating modals, optimized typography (19–20 px), hover feedback for Magic Keyboard / mouse. iOS left-edge swipe-to-go-back; header "Back" pill button; scroll position restored. 26 clinical calculators CURB-65, A-DROP, SOFA/qSOFA, LRINEC, Duke criteria, Pitt bacteremia, eGFR/CrCl, and more — accessible from each relevant disease chapter. 【Content (7 parts)】 Part 1 — Principles of ID practice (sepsis, fever/FUO, gram stain, empiric therapy, de-escalation, source control, duration) Part 2 — Organ-system syndromes (respiratory, UTI, intra-abdominal, skin/soft-tissue, CNS, bacteremia, endocarditis, bone/joint, STIs and HIV, ophthalmic, ENT, bite/trauma, immunocompromised, tropical) Part 3 — Microbe-based approach (Gram-positive/negative cocci/rods, anaerobes, atypical, mycobacteria, fungi, viruses, parasites) Part 4 — Antimicrobials (Spectrum Chart, β-Lactams, Anti-MRSA, Aminoglycosides, Quinolones, Macrolides/Lincosamides, Tetracyclines, Antimycobacterial, Antifungal, Antiviral, Antiparasitic, Quick-reference tables) Part 5 — Infection prevention (precautions, environment, devices, outbreaks, occupational exposure, HCP vaccination) Part 6 — Vaccines (pediatric, adult, pregnancy, HCP, immunocompromised, travel) — with ACIP immunity tables (MMR, Varicella) Part 7 — 26 clinical calculators 【Important notes】 This app is a clinical reference. It is NOT a substitute for clinical judgment, in-person evaluation, or institution-specific protocols. Dosing requires independent verification — especially in renal/hepatic impairment, pregnancy, pediatrics, or critical illness. Drug availability and labeling vary by country. 【Subscription】 7-day free trial; then auto-renewing monthly or yearly. Clinical Antibiogram is a subscriber-only feature. Auto-renews unless cancelled ≥24 hours before the period ends. Cancel in Apple ID Settings → Subscriptions.

Drug Interaction Checker (NEW) A Liverpool-DDI-anchored database of 295 antimicrobial drug interactions — HIV and COVID antivirals, HCV antivirals, rifamycins, azoles, macrolides, fluoroquinolones, linezolid, TMP-SMX, aminoglycosides, vancomycin, metronidazole, isoniazid, beta-lactams, and more. Severity-graded (Contraindicated / Major / Moderate / Minor / Monitor) with 13 cross-cutting patient-background alerts (G6PD, renal dosing, QT, cefepime neurotoxicity, TB hepatotoxicity, pregnancy, pediatric). Sources: FDA labels, Liverpool DDI, DHHS HIV guidelines, EASL HCV, IDSA, ATS/CDC. Searchable by generic or US brand name; potent inhibitors (e.g., Paxlovid) trigger a "confirm before prescribing" banner. Immunocompromised Host Framework (NEW) Three new sections added to "Approach to infection in the immunocompromised host (overview)": • A two-axis severity-classification plot (underlying disease burden × pharmacotherapy), anchored to NCCN Prevention and Treatment of Cancer-Related Infections, IDSA SOT/HCT guidelines, and Fishman NEJM 2007 • A 14 drug-group × T-cell / B-cell / antibody production effect matrix • A 3-tier pharmacologic immunosuppression severity table (mild / moderate / severe) With a brief cross-reference to the parallel NIID/NCGM 2024 Japanese clinical framework. Also new: "Drug Interaction Checker" entry in the antimicrobial chapter list (with NEW badge), plus a "Check Interactions" pill button on each antimicrobial detail page (current drug pre-selected). ### 1.0 — 2026-05-21 No release notes. ## More apps by Satoshi Kutsuna - [くつ王感染症クイックリファレンス](https://appshunter.io/ios/app/id6764298575) All apps by Satoshi Kutsuna: https://appshunter.io/developer/1895722022 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
