Admission-Avoidance Hospital-at-Home for Medically Complex Patients: Evidence from an Israeli Pilot to Inform National Policy
This retrospective matched cohort study of a pilot program in Israel demonstrates that admission-avoidance Hospital-at-Home care is safe and effective for medically complex internal medicine patients, showing significantly lower rates of delirium and adverse events compared to traditional hospitalization, thereby supporting the expansion of Israel's national Hospital-at-Home framework with appropriate patient selection criteria.

Hospitals are often places of healing, but for many older adults, the very act of staying there can introduce new dangers. The noise, the unfamiliar lights, the disruption of sleep, and the need to remain still for safety can trigger a sudden, severe confusion known as delirium. This state is more than just being disoriented; it is a serious medical complication that can lead to longer stays, a decline in thinking abilities, and even death. For decades, medical systems have tried to balance the need for acute, hospital-level care with the risks that come with the hospital environment. One solution that has gained traction is the "Hospital-at-Home" model. Instead of admitting a patient to a ward, a team brings the hospital's resources to the patient's living room. This approach offers continuous monitoring, daily visits from doctors and nurses, and immediate access to technology, all while the patient remains in the comfort and familiarity of their own home. While this model has shown promise for people with specific, simpler conditions, a critical question remained unanswered: could it be safe for the most medically complex patients? These are individuals with multiple chronic illnesses, taking many different medications, and requiring the intense level of care usually reserved for the inside of a hospital.
In Israel, a team of researchers decided to test this question directly. They launched a pilot program called the Hadassah-Meuhedet Hospital-at-Home, designed specifically for medically complex patients who would otherwise be admitted to an internal medicine ward. The goal was not just to see if these patients could be treated at home, but to determine if doing so was safer than keeping them in the hospital. The study focused on a group of twenty-eight patients who were enrolled in the program between September and November 2022. These individuals were elderly, suffering from conditions like heart failure, pneumonia, or severe infections, and they carried a heavy burden of other health issues. To understand if the home care was truly effective, the researchers compared these twenty-eight patients against a larger group of eighty-four similar patients who were treated in the traditional hospital wards. The two groups were carefully matched by age, sex, the number of medications they took, and the date they were admitted, ensuring that any differences in outcomes could be attributed to the location of care rather than the health of the patients themselves.
The care provided in the home was rigorous and closely mimicked the intensity of a hospital. Patients were monitored around the clock, with their vital signs checked every fifteen minutes using specialized equipment that tracked heart rate, oxygen levels, and blood pressure. A doctor and a nurse visited the home every single day, and a telemedicine platform ensured that help was available at any moment. The team also coordinated closely with the patient's health plan to manage medications and arrange for any necessary tests. The researchers looked for specific signs of trouble that often plague hospital stays: new infections, pressure sores from lying in bed, falls, and the onset of delirium. They also tracked whether patients needed to be readmitted to the hospital within thirty days, how long they stayed in care, and whether they survived for six months after the treatment began.
The results of the study offered a striking contrast between the two groups. In the hospital group, a quarter of the patients developed delirium, a sudden and severe confusion that is difficult to reverse. In the group treated at home, not a single patient developed this condition. Furthermore, while the hospital group experienced multiple adverse events, such as new infections or pressure wounds, the home group remained free of these complications. When the researchers combined all the negative outcomes into a single measure of safety, the patients treated at home fared significantly better. The only time a patient in the home program had to return to the hospital was when their condition worsened beyond what could be managed at home, but even then, the transfer was handled quickly. There was no difference between the two groups in terms of how long they needed care, how many medications they were prescribed at the end, or how often they were readmitted within a month. The six-month survival rate was also similar, though slightly higher in the home group, a difference that was not statistically significant but still noted.
A deeper look at the data revealed that the key to success was not just the location, but who was selected for the program. The researchers found that a patient's physical ability to care for themselves was the strongest predictor of whether they would have a bad outcome. Patients who were already frail or dependent on others for daily tasks faced a much higher risk of complications, regardless of where they were treated. This suggests that while the Hospital-at-Home model is safe for complex patients, it requires careful selection. It works best for those who have a supportive environment at home and a live-in caregiver, and whose medical needs can be managed with the technology and staff available in a residential setting. The study did not find that the home model was a magic bullet for every complex patient, but it did prove that for a carefully chosen group, it is a viable and safer alternative to the hospital.
This pilot program took place just before Israel began implementing a national framework for Hospital-at-Home care, a policy shift that aims to make this model a standard part of the healthcare system. The findings from this small-scale test provide crucial evidence for policymakers. They show that it is possible to extend hospital-level care to complex patients without compromising safety, provided that the right infrastructure is in place. The study highlights the importance of having a dedicated team, continuous monitoring technology, and clear protocols for when a patient needs to return to the hospital. It also underscores the need for quality measures that go beyond simple survival rates to include the prevention of complications like delirium. As the country moves toward a national system, these results suggest that the model can be scaled up, but it must be done with attention to the specific needs of the most vulnerable patients. The path forward involves balancing the high resource intensity of such a program with the clear benefits of keeping patients out of the hospital, ensuring that the system remains sustainable while delivering high-quality care.
