A cross-sectional study published in the American Journal of Infection Control examined household conditions affecting infection prevention for people receiving home healthcare. Poor lighting was the most common hazard observed, and researchers said providers may need structured ways to identify patients who need added home support. The study involved 250 patients and caregivers from two Medicare-certified agencies in New York; it does not establish that household hazards caused infections.
A study published in the American Journal of Infection Control found that household conditions such as poor lighting, clutter and vermin infestations can impede infection prevention for people receiving care at home. The cross-sectional research surveyed 250 patients and informal caregivers connected to two Medicare-certified home healthcare agencies in New York, highlighting environmental challenges that clinicians may not face in facility-based settings.
Trained research assistants conducted in-person surveys in patients’ homes, rating five conditions relevant to safe care: clutter, poor lighting, infestation, hoarding, and dirt or grime. The researchers defined clutter by how much of a surface was clear. Hoarding was treated separately, as a condition in which clutter makes a space unusable for its intended purpose.
Among respondents, 52.8% were home healthcare recipients and 47.2% were informal family caregivers; their average age was 63.5. The study found that participants’ homes were mostly clean and had moderate levels of clutter. Poor lighting was the most frequently observed hazard, followed by vermin infestation, according to the report.
The researchers also examined social factors. The report said people who had discussed difficulty paying medical bills faced higher risks of household environmental hazards and clutter. Associations were also reported between greater cleanliness and older age, identifying as Hispanic, and more favorable attitudes toward infection prevention. The study reported that higher neighborhood deprivation was associated with lower clutter scores; these findings describe associations, not causes.
Home Conditions Shape Care Delivery
Home healthcare takes place in spaces that are not designed or maintained as clinical facilities. A crowded surface may leave less room to prepare or handle supplies, while poor lighting can make care tasks harder to carry out. The study points to conditions that may affect whether patients and caregivers can follow infection-prevention instructions in their own homes.
That has practical implications for agencies planning visits and support. Lead author Margaret McDonald of VNS Health told Home Health Care News that providers could use a more structured checklist to identify households that may need additional assistance. Social workers may help connect families with decluttering or cleaning services, or with a home health aide. Those steps are possible responses described by McDonald, not interventions tested by this study.
The findings also emphasize that infection prevention is affected by more than clinical risk. Household and financial circumstances can shape the environment in which care is delivered, so identifying a hazard may point to a need for practical support rather than simply another clinical instruction.

A Survey Inside New York Homes
The study was a cross-sectional survey, meaning researchers assessed household conditions at a point in time rather than tracking changes over a period or testing a particular intervention. It included patients and caregivers served by two Medicare-certified agencies in New York. Its results therefore offer a snapshot of those participants and do not, on their own, establish how common each hazard is across all home healthcare settings.
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 care involves medically complex patients in environments unlike outpatient facilities. She said the researchers had expected people in more deprived communities to have more of the observed hazards, but the study did not find that pattern for clutter. The report instead noted an association between higher neighborhood deprivation and lower clutter scores.

Limits of the Survey Findings
The study identifies observed conditions and associations; it does not show that clutter, poor lighting or infestation directly caused infections, nor does the source report a comparison of infection rates between homes with different hazard levels. The cross-sectional design also cannot establish whether household conditions changed over time or whether changes would improve infection outcomes.
The sample came from two agencies in New York, so it is unclear how closely the results reflect home healthcare patients elsewhere. The source does not provide detailed rates for each hazard beyond identifying poor lighting as the most common and infestation as the next most common. It also does not report whether agencies have adopted the suggested checklist or support referrals.

Screening and Support in Home Care
McDonald suggested that home healthcare providers could use structured checklists to flag patients who may need extra support, with social workers helping connect households to cleaning, decluttering or home aide services. The report does not announce a specific rollout, deadline or agency policy change. Further research would be needed to test whether screening and referrals improve care conditions or infection-prevention outcomes.
For now, the findings offer providers a reason to assess the practical setting of care as well as a patient’s clinical needs. Whether agencies broadly adopt these approaches, and what effect they might have, remains unknown.

Key Questions
What did the study examine?
Researchers assessed clutter, lighting, infestations, hoarding, and dirt or grime in the homes of patients receiving home healthcare, alongside social factors that might relate to those conditions.
Which household hazard was most common?
Poor lighting was the most common hazard reported, followed by vermin infestation. The source does not provide the percentage of homes affected by each condition.
Does the study show that household hazards cause infections?
No. The study was cross-sectional and reported household observations and associations. It did not establish that a hazard caused an infection or test whether addressing hazards reduced infections.
Margaret McDonald suggested that providers consider structured checklists to identify households needing additional support. Social workers could help connect families with cleaning, decluttering or home aide services, though the study did not test these steps.
