Where Every Default Comes From
The sliders have to start somewhere. For each one, this is what is published, what is our arithmetic on published figures, and what is our own judgment. Sources checked October 2, 2026.
Patients with needle fear
Published figure- Defaults
- 63%Pediatric group
- 22%Adult clinics
- 15%Blood donation
Used as published: 63% of children (Taddio 2012), 22% of general practice patients (Wright 2009) and 14.8% of US phlebotomy patients (Deacon 2006) report needle fear. No figure exists for donors alone, so the donation setting uses the phlebotomy one.
Extra staff minutes per fearful patient
Our assumption- Defaults
- 4 minPediatric group
- 2 minAdult clinics
- 4 minBlood donation
No study has timed fearful patients against calm ones, so this is an estimate. In two pediatric trials, procedures ran 1.8 and 2.6 minutes shorter across all children when they were kept more comfortable (Taddio 2005, Aarts 2023). Half of children are highly distressed during a blood draw (Humphrey 1992), which puts the gap at about 4 minutes for each of them. A routine adult draw takes 259 seconds (Jones 2016), so 2 extra minutes is roughly half as long again. For donors, 4 minutes spreads the time a reaction takes across all fearful donors; up to 31% of fearful high-school donors reacted in one US study (France 2016).

Staff tied up during a hard procedure

In an outpatient lab trial of children aged 4 to 11, 67% needed more than one person to hold them under standard care (Chan 2019). The people holding can be parents, so set this to the staff you actually use. For adults and donors we count one.

The median wage of a medical assistant, $21.97 an hour (BLS, May 2025), divided by the 70.4% of pay and benefits that is wages in health care (BLS, June 2026), gives $31. A phlebotomist comes to the same figure, an LPN to $44 and a registered nurse to $67. Overhead and recruiting are not included.

Extra time a calmer patient gives back
Our assumption- Defaults
- 35%Pediatric group
- 35%Adult clinics
- 35%Blood donation
Pooled trials of VR and video-game distraction found no change in how long the procedure takes, and a reduced need for holding (Sajeev 2021). In the outpatient lab trial, the share of children needing more than one holder fell from 67% to 20% with a headset (Chan 2019). So the time given back is the second pair of hands and the calming before the needle, not a faster needle. 35% is our estimate; no adult or donor trial has measured it.

Extra visits kept per 100 fearful patients
Our assumption- Defaults
- 2Pediatric group
- 3Adult clinics
- 0Blood donation
In a US poll, 4% of parents of 2 to 5 year olds had postponed a vaccine and 3% had cancelled or delayed a visit because of the child's fear (Mott Poll 2018). Fear is a barrier to vaccination for 8% of children (Taddio 2022), and 16% of adult patients have avoided a flu shot over it (McLenon 2019). No trial has yet shown that a calmer visit brings those visits back: a school comfort program moved uptake from 72.5% to 76.1%, a gap that could be chance (CARD trial, Taddio 2022). We assume a calmer visit keeps about a quarter of the pediatric visits at risk and a fifth of the adult ones. For donation the default is 0, because the evidence there is about donors coming back, which the next slider counts.

Patients kept or gained per site per year
Our assumption- Defaults

- 30Blood donation
No study measures this for needle comfort, so it is the least certain number here. What is known: one in five adults left their primary care practice by choice over three years (Safran 2001); a negative online rating made parents far less likely to choose a pediatrician, odds ratio 0.09 (Hanauer 2014); and first-time blood donors returned at 82% after an uneventful donation against 55% after a reaction (Wiersum-Osselton 2014). In a trial of 8,300 young donors, simple at-the-chair interventions raised return, odds ratios 1.14 to 1.22 (Wiersum-Osselton 2022). The defaults are 6 patients a year for a clinic, one every two months, and 30 donors a year for a center, 2 in every 100 fearful donors.

Value of one visit
Our arithmetic on published figures- Defaults
- $150Pediatric group
- $100Adult clinics
- $225Blood donation
Pediatric: an established well-child visit for ages 1 to 4 ($108.89) plus two vaccine administrations ($23.38 each) at 2026 Medicare fee schedule values comes to about $156, rounded down to $150. Adult: an established office visit, $95.19, rounded to $100. Donation: the median price hospitals paid for a unit of red blood cells in 2023, $226 (Griffin 2025). These are revenue, not profit. Commercial payers tend to pay more and Medicaid less, and a vaccine-only visit is closer to $25.

Value of one patient per year
Our arithmetic on published figures- Defaults
- $325Pediatric group
- $440Adult clinics
- $400Blood donation
Primary care spending in 2019 was $324 per child and $439 per person across all ages (Decker 2023), rounded to $325 and $440 and not adjusted for inflation since. A donor gives 1.8 times a year on average (America's Blood Centers 2026); at $226 a unit that is $407, rounded to $400. Each patient or donor counts for one year only.
What the Research Does Not Show
- SendorVR itself has not been trialled for time, visit or revenue outcomes. The studies above are about needle fear, comfort programs and VR distraction in general.
- Trials of VR distraction do not show shorter procedures when pooled. The model does not assume a faster needle.
- No trial has shown that a calmer visit raises vaccination uptake beyond chance, and none links needle comfort to patients staying with a practice. Those two sliders are judgment, so move them to what you believe.
Left Out of the Number
Real effects we could not price honestly, so the result does not include them.
- Staff turnover. Replacing one medical assistant cost a US practice $14,200 (Friedman 2020). The model takes no credit for a team that finds needle visits less draining. Friedman 2020
- How the visit feels for staff. In a trial of 149 children, staff rated their satisfaction with the procedure higher when the child wore a headset (Wong 2023). Wong 2023
- Reviews and word of mouth. 28% of US parents had used a rating site to choose their child's doctor (Hanauer 2014). It counts only if you add it to the patients slider. Hanauer 2014
- Year two onward. The headset is paid for in year one, and each patient kept counts for one year only.
- Group pricing. Costs are at public list price, and groups pay less.

How the Numbers Work
No black box. This is the whole model, and the calculator runs it live in your browser.
- 1
Fearful patients
Sites × procedures per day × working days × share with needle fear. Each one gets one SendorVR session (one credit).
- 2
What fear costs today
Fearful patients × extra minutes × staff tied up, turned into hours and priced at your staff cost.
- 3
What comes back
Three parts. The share of that time you expect back. Fearful patients × visits kept per 100 × value per visit. Patients kept or gained per site × one year of their visits.
- 4
What SendorVR costs
For each site, the smallest plan whose monthly credits cover its sessions, at annual list price, plus one headset per site in year one. Groups pay less.
- 5
Net, ROI and payback
Gain minus SendorVR's cost; gain divided by cost; and the month the running gain passes the year-one cost.
SendorVR is a comfort and engagement aid, not a medical device, and it hasn't been trialled for time or revenue outcomes. The fear figures and prices are published; what a calmer visit gives back is an assumption, set out above. A 90-day pilot at 2–5 sites is how you replace it with your own data.
Prove it with your own numbers
Start with 2–5 sites for 90 days. We measure sessions and staff ratings in Studio; you measure visit times and return visits. Then decide on rollout.
