Animals in Healthcare Facilities: Recommendations to Minimize Potential Risks

Open access

Abstract

Animals may be present in healthcare facilities for multiple reasons.Although specific laws regarding the use of service animals in public facilities were established in the United States in 1990, the widespread presence of animals in hospitals, including service animals to assist in patient therapy and research, has resulted in the increased presence of animals in acute care hospitals and ambulatory medical settings.The role of animals in the transmission of zoonotic pathogens and cross-transmission of human pathogens in these settings remains poorly studied.Until more definitive information is available, priority should be placed on patient and healthcare provider safety, and the use of standard infection prevention and control measures to prevent animal-to-human transmission in healthcare settings.This paper aims to provide general guidance to the medical community regarding the management of animals in healthcare (AHC).The manuscript has four major goals:1. Review and interpret the medical literature regarding risks and evidence for animal-to-human transmission of pathogens in the healthcare setting, along with the potential benefits of animal-assisted activities in healthcare.2. Review hospital policies related to AHC, as submitted by members of the SHEA Guidelines Committee.3. Summarize a survey that assessed institutional AHC policies.4. Offer specific guidance to minimize risks associated with the presence of AHC settings.Recommendations for the safe oversight and management of AHC should comply with legal requirements and minimize the risk of transmission of pathogens from animals to humans when animals are permitted in the healthcare setting.Although little published literature exists on this topic, we provide guidance on the management of AHC in four categories: animal-assisted activities, service animals, research animals, and personal pet visitation.Institutions considering these programs should have policies that include well-organized communication and education directed at healthcare personnel (HCP), patients, and visitors.Appropriately designed studies are needed to better define the risks and benefits of allowing animals in the healthcare setting for specific purposes.

TL;DR

This SHEA white paper offers expert-opinion guidance for managing animals in acute care and ambulatory facilities—animal-assisted activities, service animals, research animals, and personal pet visitation—to reduce pathogen transmission risks. It synthesizes limited literature, 23 submitted hospital policies, and a 2013 SHEA survey (337 respondents, 21.7% response) and concludes that evidence is insufficient for formal guidelines.

Key findings

  • The evidence base is weak: the paper states few scientific studies address animal-to-human transmission in healthcare and insufficient studies exist for generalizable, evidence-based recommendations; recommendations are expert-opinion-based and not GRADE-graded.
  • Survey of SHEA membership/SHEA Research Network: 337 respondents (21.7% of 1,550); 93% acute care, 77% US. Among facilities allowing animals, some lacked formal policies: animal-assisted activities 5.8% (18/306), service animals 4.3% (12/279), research animals 8.5% (11/130), personal pet visitation 5.8% (7/121); 8 US facilities, including a Veterans Hospital, reported not allowing service animals.
  • Policy review: 23 facilities submitted policies; 20 addressed animal-assisted activities, 18 service animals, one-third research animals, and 13 allowed personal pet visitation. Most animal-assisted activities used dogs almost exclusively, though 3 policies allowed cats or miniature horses; service-animal policies commonly required vaccination/health certification, housebreaking, leash control, and patient/designee responsibility for care.
  • Risk examples: in one study of 102 healthy visitation dogs, zoonotic agents were isolated from 80%, including toxigenic *Clostridium difficile* 40.1%, *Salmonella* spp. 3%, ESBL/cephalosporinase *E. coli* 4%, *Pasteurella* spp. 29%, *Malassezia pachydermatis* 8%, *Toxocara canis* 2%, and *Ancylostoma caninum* 2%. An ICU nursery outbreak of *M. pachydermatis* involved 15 case patients, 9 colonized infants, 1 healthcare worker, and 3 pet dogs, with 8 bloodstream infections, 2 urinary tract infections, 1 meningitis, and 4 asymptomatic colonizations.

Methods

  • Design: SHEA white paper/guidance document with narrative literature review, review of submitted institutional policies, and cross-sectional survey.
  • Data/sample: 23 healthcare facility policies submitted by writing group/SHEA Guidelines Committee members; SHEA Membership and SHEA Research Network survey February–May 2013, 337 respondents (21.7% of 1,550), mostly acute care (93%) and US (77%); only 24 non-US respondents linked to institution-identifying information were analyzed.
  • Analysis: synthesized limited evidence, theoretical rationale, practical considerations, survey results, and writing group opinion; no formal evidence grading (e.g., GRADE) was used.

Limitations

  • Stated: the topic lacks the level of evidence required for a formal guideline; no grading of evidence is provided; recommendations are suggested actions, not recognized standards or regulations, and adoption is at institutional discretion.
  • Stated: few scientific studies and minimal case-report/outbreak experience exist; insufficient studies are available for generalizable, evidence-based recommendations; the document is intended only for acute care hospitals and ambulatory facilities, not assisted living, nursing homes, or extended care facilities.
  • Stated/evident: the survey had a 21.7% response rate and only 24 non-US institutions were analyzed; the policy review relied on submitted policies, and not all facilities with animal programs had formal policies, so findings may reflect self-selection and variation in practice.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

A language model drew the claims from the paper on 2026-11-10, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).

A second model labelled each claim on 2026-11-10 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
