HOUSE CALLS
House Calls, LLC
Fewer hospital-acquired infections. Smarter antibiotic use.
House Calls helps acute care, long-term care and inpatient rehabilitation facilities prevent CAUTI, CLABSI, VAP and C. difficile, and build antimicrobial stewardship that holds up at accreditation time.
1 in 31
hospital patients has at least one healthcare-associated infection on any given day (CDC).
Vision
U.S. and global healthcare facilities that implement evidence-based standards for infection control and antimicrobial stewardship to improve patient outcomes.
Mission
Our mission is to provide comprehensive advisory and AI-enabled solutions to U.S. and global healthcare facilities on infection control; surveillance; mitigation of multidrug-resistant pathogens; antimicrobial stewardship; and technology systems including emergency operations centers (EOCs).Â
Infection Prevention, Control & Stewardship Services
We work closely with staff involved in infection control to significantly reduce infection rates and optimize antimicrobial use through evidence-based protocols and clinical expertise.
C difficile infection (CDI)
Minimize CDI transmission and recurrence with advanced environmental controls and clinical surveillance, leading to safer patient outcomes.
Catheter-Associated UTIs
Reduce CAUTI incidence through rigorous device-necessity reviews and evidence-based insertion and maintenance protocols for clinical teams.
Central Line Bloodstream Infections (CLABSI)
Eliminate preventable bloodstream infections by implementing standardized central line care bundles and continuous staff competency validation.
Ventilator-Associated Pneumonia (VAP)
Improve respiratory outcomes and shorten ventilator days with specialized surveillance and multi-disciplinary weaning and care strategies.
Antimicrobial Stewardship
Optimize antibiotic selection and duration to combat resistance, ensuring your facility meets compliance standards and provides safer patient care.
Our six-step method
Every engagement follows the same six steps, measured with your own data and reported to leadership.
1. Define the problem: A six-month review of your infection, pathogen, MDRO and prescribing data by unit, including impact on length of stay.
2. Review practice at the bedside: Twice-weekly review of every catheter, central line, ventilated patient or antimicrobial prescription, supported by AI-driven appropriateness scores.
3. Sharpen diagnosis and antibiotic use: Separate true infection from colonization and identify stewardship and formulary savings.
4. Educate your teams: Bi-monthly in-service education and competency validation for nursing, respiratory therapy and medical staff.
5. Hard-wire best practices: Root cause analysis for each infection, stop orders, guidelines and PDSA cycles, tracked on 60- and 90-day dashboards.
6. Define success: Agree on metrics with leadership, such as percent reduction in infections, unnecessary devices, inappropriate antimicrobials and length of stay.
What each program covers
CAUTI
- Twice-weekly review of every urinary catheter with removal recommendations
- Audit of insertion technique and care bundles
- Separate true UTI from colonization to cut needless antibiotics
Success: fewer CAUTIs, unnecessary catheters and inappropriate antibiotics.
CLABSI
- Daily review of whether each central line is still needed
- Bedside audits of insertion (checklist, maximal sterile barrier, chlorhexidine-alcohol skin prep) and maintenance (hub disinfection, dressings, chlorhexidine bathing)
- Blood culture practice and contamination rates
Success: lower CLABSI rate and SIR, fewer line days, higher bundle compliance.
VAP
- Surveillance aligned with NHSN ventilator-associated events
- Ventilator bundle: head of bed 30-45 degrees, paired daily sedation interruption and breathing trials, oral care, early mobility
- Separate pneumonia from airway colonization and shorten antibiotic courses
Success: fewer VAEs, ventilator days and ICU days.
C. difficile
- Contact precautions, hand hygiene and sporicidal cleaning audits
- Diagnostic stewardship so testing finds true infection
- Review of high-risk antibiotics and acid suppression
Success: less hospital-onset CDI and recurrence.
Antimicrobial stewardship
- AI-driven appropriateness score and twice-weekly audit of every prescription
- Guidelines for pneumonia, UTI, skin and soft tissue infection and fever
- Formulary restriction, pre-authorization and stop orders
Success: fewer inappropriate antimicrobials, lower formulary costs, shorter stays.
Clinical, global health and AI, in one team
House Calls brings together three disciplines that rarely sit at the same table: bedside infectious-disease medicine, global public-health epidemiology, and modern IT, AI and data science. The result is infection prevention and stewardship that is clinically sound, grounded in population-level evidence, and powered by the latest AI models.
Clinical: Infectious-disease physicians and infection preventionists who review cases, audit practice at the bedside, and teach your teams.
Global health: Epidemiologists with decades at CDC, DoD and international agencies, bringing surveillance methods proven across health systems and borders.
IT, AI and data science: The latest AI models read the record, flag at-risk patients and devices, and check antibiotic use against guidelines, continuously rather than only at audit time.
Intelligence as a Service
Instead of selling you software to install and maintain, we deliver intelligence as a service. Our AI and analytics run on your data, and our experts turn the output into decisions your staff can act on. You get the insight without building your own data science team.
- AI-assisted surveillance for CAUTI, CLABSI, VAP and C. difficile
- Antibiotic appropriateness review at scale
- Clear dashboards and reports for your teams and accreditors
- Expert human review of every AI flag
Leadership
Led by physicians and epidemiologists. House Calls was founded in 2025 as a Florida LLC. Our leadership has more than 50 years of combined experience in health systems design and quality implementation in the U.S. and internationally.
Supported by an Infection Control Nurse Practitioner (bedside audits and staff competency) and a Master's-trained Data Scientist (dashboards, scoring models and data pipelines).
