A cross-sectional study of 250 home health patients and family caregivers in New York found that household conditions such as poor lighting, clutter and vermin can impede infection prevention at home. The findings point to the value of identifying environmental and social needs, but do not establish that specific hazards caused infections or measure infection rates.
A study of 250 home health patients and family caregivers in New York found that household conditions including poor lighting, clutter and vermin can complicate infection prevention during care at home, highlighting how care teams may need to account for patients’ living environments. The cross-sectional study, published in the American Journal of Infection Control, assessed home hazards but did not establish that they caused infections.
Trained research assistants conducted in-person surveys in patients’ homes connected to two Medicare-certified home health agencies in New York. Of the 250 respondents, 52.8% were people receiving home health care and 47.2% were informal family caregivers. Respondents had an average age of 63.5. Researchers rated five conditions relevant to safe care: clutter, poor lighting, infestation, hoarding, and dirt or grime.
The study reported that participants’ homes were generally clean and had moderate amounts of clutter. Poor lighting was the most common hazard, followed by vermin infestation. The researchers treated clutter and hoarding as separate conditions: clutter described how much a surface was crowded, while hoarding referred to clutter that made a space unusable for its intended purpose.
The report also described associations between household conditions and respondent characteristics. Older age, identifying as Hispanic, and more favorable attitudes toward infection prevention were associated with greater cleanliness. People who reported difficulty paying medical bills had higher environmental hazard risks and clutter, according to lead author Margaret McDonald. These findings describe associations in the study sample, not proof that any characteristic or circumstance caused a particular home condition.
How Home Conditions Shape Care
Home health workers deliver clinical care in spaces that were not necessarily designed for treatment. A crowded counter may leave little room to prepare supplies, while inadequate lighting can make it harder to see or follow care instructions. Those are practical concerns for infection prevention, though the study did not test specific clinical outcomes or show how often a household hazard led to an infection.
The findings also point to a need to look beyond clinical factors when planning support for patients. Environmental conditions and financial strain may affect whether a care plan can be carried out as intended. A structured screening process could help agencies identify when a patient or family may need additional help, such as cleaning, decluttering, or a home health aide. The report describes these as possible responses, rather than interventions evaluated by the study.
For patients and caregivers, the issue is relevant because infection-prevention instructions must work in the home where care takes place. Recognizing hazards can help providers discuss practical barriers with families and consider appropriate support without assuming that a cluttered or poorly lit home reflects a lack of concern about health.

What the New York Study Examined
The study used a cross-sectional design, meaning researchers assessed household conditions and respondent information at a particular period rather than tracking changes over time. Its sample came from patients and caregivers associated with two Medicare-certified agencies in New York; the findings should not automatically be treated as representative of all home health patients or locations.
Researchers scored household hazards on a one-to-five scale. For clutter, the report defined a surface that was 90% to 100% clear as having no clutter, and one that was 0% to 49% clear as very cluttered. McDonald, the study’s lead author and associate vice president of the Center for Home Care Policy and Research at VNS Health, told Home Health Care News that home-based clinicians do not have the same environment as staff in outpatient settings. The research focused on how that difference may affect infection control and prevention.

Limits of the Findings
The study assessed household conditions and reported associations; the source report does not provide evidence that the hazards caused infections, nor does it give infection-rate comparisons between homes with different conditions. Its cross-sectional design also cannot establish which conditions came first. The findings are based on 250 respondents connected to two New York agencies, and the supplied report does not establish how well they apply to other regions or home-care populations.
The source material does not specify the exact publication date, provide detailed hazard-score distributions, or describe whether researchers followed patients after the assessments. It also does not report whether a checklist or additional home-support services were implemented and tested. Those details would be needed to judge the scale of the problem and which responses improve infection-prevention outcomes.

Screening and Support Options
McDonald suggested that home-care providers could use a more structured checklist to identify patients who may need additional support. Social workers could help connect families with services for cleaning or decluttering, or with a home health aide, according to her comments. The report presents these as potential steps, not as a program with demonstrated results.
The next questions for providers and researchers include whether routine screening can identify practical barriers consistently, what services families can access, and whether those supports improve infection-prevention practices or patient outcomes. The supplied report does not identify a planned follow-up study or a timeline for new guidance.

Key Questions
What household hazards did the study assess?
Researchers assessed clutter, poor lighting, infestation, hoarding, and dirt or grime in the living spaces of home health patients.
Which hazard was most common?
Poor lighting was the most common hazard reported, followed by vermin infestation. The study sample was drawn from two Medicare-certified agencies in New York.
Did the study show that household hazards caused infections?
No. The study examined home conditions and their relationship to infection prevention and control, but the available report does not establish that hazards caused infections or provide infection-rate comparisons.
Margaret McDonald suggested that providers could use structured checklists to identify needs and that social workers could connect families with cleaning, decluttering, or home health aide services. These were proposed options, not interventions tested in the study.
