A cross-sectional study of 250 home healthcare patients and family caregivers in New York found that conditions such as poor lighting, clutter and infestations can complicate infection prevention in the home. The researchers say providers may need structured assessments and links to household support, though the study does not establish that these hazards caused infections.
A study of 250 home healthcare patients and caregivers in New York found that household conditions—including poor lighting, clutter and vermin infestations—can impede infection prevention and control in the home. Published in the American Journal of Infection Control, the research highlights why care providers may need to assess living conditions and connect some households with additional support, alongside clinical care.
Researchers surveyed people served by two Medicare-certified home healthcare agencies. The group included 52.8% care recipients and 47.2% informal family caregivers, with an average age of 63.5. Trained research assistants conducted in-person surveys in patients’ living spaces and rated five potential hazards: clutter, poor lighting, infestation, hoarding, and dirt or grime.
The study found that participants’ homes were generally clean and had moderate levels of clutter. Poor lighting was the most common hazard, followed by vermin infestation. The researchers also examined social factors. Participants who reported difficulty paying medical bills had higher household environmental hazard risks and clutter, according to the study’s lead author, Margaret McDonald of VNS Health.
The authors distinguished ordinary clutter from hoarding: clutter was assessed by how much of a surface remained clear, while hoarding referred to clutter that made a space unusable for its intended purpose. The study’s findings describe associations and observed conditions; they do not show that a particular household hazard caused an infection or a specific care outcome.
Why Home Conditions Affect Care
Home healthcare takes place in environments that are not designed or controlled like clinics. A crowded counter may leave less usable space for a clinical task, while dim lighting can make it harder to see or follow care instructions. These conditions can complicate infection prevention for patients and clinicians, especially when care depends on a suitable surface and the ability to carry out recommendations safely.
The findings point to a practical issue for agencies: infection prevention may require attention to a patient’s surroundings as well as medical needs. McDonald told Home Health Care News that providers could use a structured checklist to identify people who may need extra help. Social workers may then connect families with services such as decluttering, cleaning or a home health aide. The report does not measure the effectiveness of these interventions, but it identifies them as possible responses to household risks.

How Researchers Assessed Homes
The research addressed a distinct challenge of home-based care: clinicians deliver services in patients’ own living spaces, where conditions can vary from one household to another. The study’s authors considered environmental hazards alongside social determinants of health that may affect infection prevention and control.
McDonald said the researchers had expected more observed hazards in communities with greater deprivation, but that expectation was not borne out in their results. The study instead reported that higher neighborhood deprivation was associated with lower clutter scores. It also found associations between greater cleanliness and older age, identifying as Hispanic, and more favorable attitudes toward infection prevention and control. These are observed relationships, not evidence that any demographic or neighborhood factor directly causes a home to be cleaner or safer.

Limits of the New York Survey
The study covered 250 respondents connected to two agencies in New York, so its results may not represent home healthcare patients in other regions or care systems. The source report does not provide enough detail to determine how common each hazard would be across a broader population, or whether the patterns would hold over time.
The research measured household conditions and reported associations; it does not establish that poor lighting, clutter or infestation led to infections. It also remains unclear whether checklist-based assessments or referrals to cleaning, decluttering or home aide services would measurably improve infection prevention outcomes. The supplied report does not give a publication date for the journal article beyond its October 2026 coverage.

How Agencies Could Respond
McDonald suggested that providers consider a more structured way to identify households that may need additional support. That could include reviewing the home environment during care and involving social workers when a family needs help finding cleaning, decluttering or aide services. The study does not announce a new agency policy or a tested intervention; these steps were presented as possible ways to respond to identified risks.
Further research would be needed to test whether such assessments and referrals improve infection prevention, and to establish how broadly the findings apply beyond the two New York agencies. For now, the report’s immediate message is that clinicians may need to account for the practical conditions in which home care is delivered.

Key Questions
What did the study find?
In a survey of 250 home healthcare patients and caregivers in New York, poor lighting was the most common household hazard identified, followed by vermin infestation. Homes were generally clean and had moderate clutter, according to the report.
Did the study show that household hazards cause infections?
No. The study examined home conditions and infection-prevention challenges, but the reported findings do not establish that hazards caused infections or other specific clinical outcomes.
What support might providers offer?
Lead author Margaret McDonald suggested using a structured checklist to identify households that may need added support. Social workers could help connect families with cleaning, decluttering or home aide services.
How widely do the findings apply?
The survey involved patients and caregivers served by two Medicare-certified agencies in New York. The report does not establish whether the findings represent home healthcare populations elsewhere.
