Discharge delays cost 52 hospitals an estimated $169 million in one quarter

Under Medicare's DRG payment, a hospital is paid a set rate per admission, roughly the same whether the patient stays four days or nine. Every day a medically ready patient waits for a nursing-facility bed, a prior authorization, or a home-health start date, the hospital pays for the bed with no added revenue.

In one state hospital association's survey, 52 New York hospitals counted roughly 60,000 delay days in one quarter of 2022, at an estimated $169 million. The inpatient share, from 50 of those hospitals, was $167 million across 58,710 days.

The delay days are concentrated among patients headed to post-acute care, such as a skilled nursing facility or home health, and those patients' hospital stays have grown longer. An American Hospital Association brief, using data from Strata Decision Technology, showed average length of stay up 19.2% between 2019 and 2022, and nearly 24% for patients discharged to post-acute settings before adjusting for case mix (15.4% after). Referral data from that period showed skilled nursing facilities turning down most referrals: 52% in 2019, 57% in 2021 and 65% in January 2022. Case managers work down a list by fax and phone while the patient waits.

Treat discharge as a queue

Little's Law says the average number of patients in a hospital equals the arrival rate times the average length of stay. A hospital can't schedule its emergency arrivals, so the levers it has over census are the elective surgery schedule and length of stay. The cheapest hospital days to cut are the ones a patient spends waiting after their care is finished.

Full inpatient units also back up the rest of the hospital. When beds don't empty, admitted patients wait in the emergency department, which is called boarding. Boarding shows up in the ED, but officials at CMS and the Agency for Healthcare Research and Quality, writing in 2025, said its causes lie far beyond the ED, in patient flow across the whole hospital, including delayed inpatient discharges. A hospital moves patients only as fast as its slowest step (the binding constraint), so an hour saved at any other step does not move patients through any faster.

Where the fixable delay is

Walk the discharge path and label each step clinical or administrative. In the New York survey, the most common cause of delay was finding a place that would take the patient, and the work around that search is administrative: assembling and sending referral packets, waiting for facility responses, chasing payer authorization, and arranging transport. These steps can be measured from data the hospital already has. They run on documents and phone calls, which automation handles well. These steps cross departments, so it is worth asking whether any one person is responsible for how long they take from start to finish.

The Institute for Healthcare Improvement wrote in 2020 that efforts to improve patient flow in most hospitals are often siloed, with departments pursuing priorities that sometimes conflict. Whether the fix is a capacity command center or a dedicated placement team, start by measuring the queue, putting a price on each day of delay and making one person accountable for the number.

Three questions

If you run a hospital, three questions show whether this applies to you. How many bed-days last quarter went to patients who were medically ready to leave? What was the average time from discharge order to departure for patients going to post-acute care? Who, by name, is responsible for reducing it? If the first two take more than a week to answer, that alone tells you nobody is tracking these delays.
