A cross-sectional study of 250 patients and informal caregivers served by two New York home-health agencies found household hazards that may complicate infection prevention. Poor lighting was the most common hazard, followed by vermin infestation; researchers say providers may need better ways to identify people who need added home support.
A study published in the American Journal of Infection Control found that household conditions such as poor lighting, clutter and vermin infestation can complicate infection prevention for people receiving care at home. The cross-sectional study surveyed 250 patients and informal caregivers connected to two Medicare-certified home-health agencies in New York, highlighting environmental factors providers may need to account for when planning care.
Trained research assistants surveyed participants in their living spaces and rated five hazards relevant to safe care: clutter, poor lighting, infestation, hoarding, and dirt or grime. The researchers assessed clutter based on how much of a surface remained clear. They distinguished it from hoarding, which they defined as clutter that makes a space unusable for its intended purpose.
Of the respondents, 52.8% were home-health recipients and 47.2% were informal family caregivers. Their average age was 63.5. Participants’ homes were generally described as clean, with moderate amounts of clutter. Poor lighting was the most common hazard, followed by vermin infestation, according to the study account.
The researchers also examined social factors. People who reported difficulty paying medical bills had higher risks of household environmental hazards and clutter, lead author Margaret McDonald told Home Health Care News. The study found associations between several respondent characteristics and home conditions, but it did not establish that those characteristics caused the conditions.
Home Conditions Shape Care Delivery
Home-health workers deliver clinical care in spaces that were not designed as treatment rooms. Crowded surfaces may leave less room to prepare or handle supplies, while poor lighting can make care tasks harder to carry out. The study does not measure infection rates or show that a particular hazard caused an infection; it documents conditions that can make infection-prevention practices more difficult to follow.
That distinction matters for patients and families because care plans may depend on what can realistically be done in a home. If a clinician identifies environmental barriers, the response may involve support beyond clinical instructions. McDonald suggested that agencies use a structured checklist to identify households that could benefit from additional help, including cleaning, decluttering or a home-health aide. Social workers may help connect families with those services.
The findings also put attention on financial strain as a possible signal of greater environmental needs. A patient’s infection-prevention risks may reflect both medical needs and the practical conditions in which care is delivered. Recognizing those conditions can help providers decide where further assessment or support is needed, though the study does not test whether any specific intervention improves outcomes.

How Researchers Assessed Homes
The study was a cross-sectional survey, meaning researchers collected observations at one point rather than tracking households over time. It involved patients and caregivers from two Medicare-certified agencies in New York, so its results describe that sample and should not automatically be treated as representative of all home-health settings.
Researchers rated hazards during in-person visits. For clutter, a space that was 90% to 100% clear received the no-clutter description; a space that was only 0% to 49% clear was considered very cluttered. The authors treated hoarding separately, based on whether clutter prevented a space from serving its intended use.
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 that differ from outpatient settings. She said the researchers had expected more hazards in communities with greater deprivation, but that expectation was not borne out in their observations.

Limits of the Study Findings
The study’s cross-sectional design records household conditions and reported factors at one point in time. It cannot establish which conditions cause others, whether hazards changed over time, or whether the observed risks led to infections. The supplied report does not provide infection-rate outcomes or evidence that a checklist, cleaning service or other proposed support reduced infections.
The sample came from two agencies in New York, and the findings may not reflect homes served by other providers or in other regions. The report also does not specify the size of the associations between the identified social factors and household hazards. It remains unclear which interventions would be most effective, how agencies would fund them, and how often providers should assess home conditions.

Provider Screening and Support
McDonald suggested that home-health agencies consider using more structured checklists to flag patients who may need additional household support. Social workers could then help families seek services such as decluttering, cleaning or a home-health aide, depending on what is available and appropriate.
The study account does not announce a new mandate or a confirmed rollout of such a checklist. Further research would be needed to test whether screening and added services improve infection-prevention practices or patient outcomes. For now, the findings point to a practical next step for providers: assess relevant home conditions as part of care planning, while recognizing that the best response may depend on each patient’s needs and resources.

Key Questions
What did the study find?
Researchers found that household hazards can complicate infection prevention in home healthcare. Poor lighting was the most common hazard in the study sample, followed by vermin infestation; homes were generally clean and had moderate clutter.
Who took part in the study?
The study included 250 patients and informal family caregivers connected to two Medicare-certified home-health agencies in New York. Patients made up 52.8% of respondents, and caregivers made up 47.2%.
Does the study show that household hazards cause infections?
No. The cross-sectional study assessed home conditions and related factors; the reported findings do not establish that a hazard caused an infection or quantify infection outcomes.
Margaret McDonald suggested that providers could use a structured checklist to identify people who may need additional help. Social workers may connect families with decluttering, cleaning or home-aide services.
