Moral distress occurs when one knows the ethically correct action to
take but feels powerless to take that action.
Do we cause this with our leadership and expectations?
Moral distress

• Server capacity x cycle time = Work In Process• Arrivals per hour x LOS = Patients in the ED
• Apply it to the whole ED or Unit• Apply to each pod or doctor or nurse• Go to Wikipedia!
Little’s Law: Match demand and capacity.
![Page 10: Emergency Department Performance: BEHIND THE NUMBERS Todd Lang, MD, MBA Medical Director of Emergency Services Baptist Memorial Hospital-Memphis](https://reader033.vdocuments.net/reader033/viewer/2022051000/56649e3f5503460f94b308dc/html5/thumbnails/10.jpg)
• LOS = 4 hours• Doc sees 2 pts/hr (on average)• 2 x 4 = 8, but if can see 3/hr then 3 x 4 = 12• Need 8 beds to be busy IF AT AVERAGE
• Doc work ends at admit order (not true for nurse)• Some patients are easier, and some days there
are holds, so need a few extra beds• So, need 12 - 14 beds per doc to account for this• But, 16 is unmanageable in most situations
Sample doc calculation Using Little’s Law

• Follow the value!• Map the stream and remove the waste• Give staff time to engage patients• Leverage fungible staff substitutions:
– Lab/X-ray subs for ED staff!– Paramedic substitutes for RN– RN subs for Doctor– Hospitalist subs for ED doctor
Shift the curve:
![Page 14: Emergency Department Performance: BEHIND THE NUMBERS Todd Lang, MD, MBA Medical Director of Emergency Services Baptist Memorial Hospital-Memphis](https://reader033.vdocuments.net/reader033/viewer/2022051000/56649e3f5503460f94b308dc/html5/thumbnails/14.jpg)
• Know the cost of a walkout• Know the value of a bed-hour• Do the math on LOS changes and staffing• What is the value of shorter LOS in nursing
cost?• What is the value of increased physician
productivity?

• Demand:capacity matching• By day of week and hour• Differential scheduling by day?• Nurse and doc must match!• How about housekeeping and transport and
CT servers?

What do you get if you overdo D2D?
D2D: Slice and dice it!

Is it low because of lack of patients?

• By doctor• By disease and by doctor• CHF• Chest pain• Abdominal pain
Why does it vary so much?
Admission rate
![Page 21: Emergency Department Performance: BEHIND THE NUMBERS Todd Lang, MD, MBA Medical Director of Emergency Services Baptist Memorial Hospital-Memphis](https://reader033.vdocuments.net/reader033/viewer/2022051000/56649e3f5503460f94b308dc/html5/thumbnails/21.jpg)
• Lab• CT • Morphine equivalents• Total pharmacy cost per patient• Admit• Obs• Total cost
Use the info to coach and ask the right questions! Let the high performers teach the rest.
Utilization by doctor or by disease or both!

• By CT groups: – brain/C-spine– Chest/belly w/IV only
• X-ray:– Portable chest– Others
• Study vs. reading on each of above• By hour of day
Radiology
![Page 23: Emergency Department Performance: BEHIND THE NUMBERS Todd Lang, MD, MBA Medical Director of Emergency Services Baptist Memorial Hospital-Memphis](https://reader033.vdocuments.net/reader033/viewer/2022051000/56649e3f5503460f94b308dc/html5/thumbnails/23.jpg)
• A significant fraction of your patients are waiting for a CT result
• CT rate often is in the neighborhood of admit rate
• Cannot dispo until CT is done and read• This key server requires management• The radiologists probably won’t volunteer to
perform better (see demand:capacity chart).
The ED alone can rarely manage this process.
CT, in particular
![Page 24: Emergency Department Performance: BEHIND THE NUMBERS Todd Lang, MD, MBA Medical Director of Emergency Services Baptist Memorial Hospital-Memphis](https://reader033.vdocuments.net/reader033/viewer/2022051000/56649e3f5503460f94b308dc/html5/thumbnails/24.jpg)
• Med pick and delivery times• Frequency of med send and what drugs• Frequency of stockouts in ED
Time for pharmacy
![Page 25: Emergency Department Performance: BEHIND THE NUMBERS Todd Lang, MD, MBA Medical Director of Emergency Services Baptist Memorial Hospital-Memphis](https://reader033.vdocuments.net/reader033/viewer/2022051000/56649e3f5503460f94b308dc/html5/thumbnails/25.jpg)
• Measure best care, not just the core measures• “consensus committee” or some other way to
decide what good care looks like• Wildly different than CMS deciding for you
• Easy examples: – imaging rules for head and neck – completion of NIHSS for stroke– time to pain meds for fractures– sepsis care
Beyond Core Measures
![Page 26: Emergency Department Performance: BEHIND THE NUMBERS Todd Lang, MD, MBA Medical Director of Emergency Services Baptist Memorial Hospital-Memphis](https://reader033.vdocuments.net/reader033/viewer/2022051000/56649e3f5503460f94b308dc/html5/thumbnails/26.jpg)
• What does this incentivize?• Why is it so fundamentally at odds with
“doctorhood”?• How does it fit with our national pill problem?• Do the people around you actually understand
percentiles and how that works?• Does the hospital understand common cause
variation?
The biggest miss: pay for satisfaction
![Page 27: Emergency Department Performance: BEHIND THE NUMBERS Todd Lang, MD, MBA Medical Director of Emergency Services Baptist Memorial Hospital-Memphis](https://reader033.vdocuments.net/reader033/viewer/2022051000/56649e3f5503460f94b308dc/html5/thumbnails/27.jpg)
• Call back time?• ED physician satisfaction (particularly if paid)• Time to definitive care• Supply use for surgical cases• Measuring and reporting it is almost as good
as putting it in the contract, but without the contention.
On Call: measure it if you bought it!
![Page 28: Emergency Department Performance: BEHIND THE NUMBERS Todd Lang, MD, MBA Medical Director of Emergency Services Baptist Memorial Hospital-Memphis](https://reader033.vdocuments.net/reader033/viewer/2022051000/56649e3f5503460f94b308dc/html5/thumbnails/28.jpg)
• Managing readmissions is at odds with ED flow• Is it easier to readmit than other options?
– Social work?– Inpatient doctor consult?– Ethics consult?– Palliative care?– Talk to the NH doctor?
• All take time and have limited resources!
• Providing resources will move the needle
Readmissions vs. flow
![Page 29: Emergency Department Performance: BEHIND THE NUMBERS Todd Lang, MD, MBA Medical Director of Emergency Services Baptist Memorial Hospital-Memphis](https://reader033.vdocuments.net/reader033/viewer/2022051000/56649e3f5503460f94b308dc/html5/thumbnails/29.jpg)
• Conditional formatting works• (S)He who controls the dashboard file has
considerable control!• Much like control of the meeting agenda!
Dashboard: goals and colors

and cannot look away.”- Dr. Thomas Lee: Turning Doctors Into Leaders,
