The referral date is part
of the treatment

What the strongest study found

The most direct evidence comes from the Workers Compensation Research Institute (WCRI). Its 2020 study — The Timing of Physical Therapy for Low Back Pain: Does It Matter in Workers' Compensation? — followed roughly 26,000 lost-time low-back claims across 27 states, Maryland among them, and compared workers whose physical therapy began within 3 days of injury with workers whose therapy began more than 30 days after it.

The late-start group did worse on every outcome the study examined:

The pattern continues into the file itself. Claims where therapy started late ran 24% higher in medical cost per claim, and attorney involvement reached 27% in the late-therapy group, against 13–15% when therapy started promptly. Every figure in this section is from the same WCRI study; the full citation is at the bottom of this page.

Cited honestly: this is an observational study, not a randomized trial — a claim where therapy starts late can differ from an early-therapy claim in other ways too, and no single study should carry more weight than it earns. What earns this one its place is size, scope and consistency: tens of thousands of claims, 27 states, five separate outcomes — and every one of them pointing the same direction. Later is worse.

The window closes faster than it feels

The New York State Workers' Compensation Board — a regulator with no rehabilitation to sell — puts the stakes plainly on its employer return-to-work page: "only half of injured workers will return to work after a six-month absence," and fewer still as the absence stretches on.

Six months sounds like runway. On a comp claim it is spent a few unremarkable weeks at a time — a referral that waits on records, an authorization that idles, a schedule that slips into next month. No single delay looks decisive, and none of them is anyone's fault. The total is what the WCRI numbers are measuring.

Why absence itself does harm

The timing effect is not a paperwork artifact. There is a clinical mechanism behind it, and it has been understood for two decades.

In 2006, Gordon Waddell and Kim Burton published Is Work Good for Your Health and Well-Being?, a comprehensive review of the evidence. Their conclusion: yes — work is generally good for physical and mental health, and long absence from it is associated with worse health on both fronts. For an injured worker, time away from work is not a neutral holding pattern while the body heals. The absence carries risk of its own.

The American College of Occupational and Environmental Medicine reached the same conclusion the same year. Its 2006 report, Preventing Needless Work Disability by Helping People Stay Employed, argues that prolonged absence is often harmful in itself, that much of the long-term work disability the system produces is preventable, and that the first days and weeks after an injury matter most — the trajectory of a claim is set early, while everyone involved still assumes there is plenty of time. ACOEM's practical advice is a habit the best referrers already have: ask the physician about functional ability — what the worker can do — not just work status.

What we control — and what we commit to

Scheduling in workers' comp depends on authorization, the claimant and a dozen things none of us control. The rest of this site refuses to publish a number it can't hold, and this page is no exception — you will not find an invented "days to first visit" promise here. What you will find is the part of the timeline that is ours, committed to:

• Send what you have. Don't hold a referral waiting on records or a job description — refer with what exists today and the rest can follow. We verify coverage and obtain authorization before the first visit.
• The FCE report is sent within 72 hours of the evaluation being completed, to everyone listed on the referral — the same commitment stated on our FCE page, because the document is the part of the turnaround we fully control.
• You hear about a missed session the day it happens. Attendance is reported to the referrer day-of, not in a summary weeks later.

One ask: treat the referral date as clinical

If this page changes one habit, let it be this. The referral date is not an administrative detail that trails the clinical decisions — on the evidence above, it is a clinical decision. Write the rehab referral the day the need is identified, the way a time-sensitive prescription would be written, and let the records catch up in transit.

And that holds wherever you send the worker. This page argues for a date, not a destination — refer to us or to someone else, but refer early.
