NEDOCS models emergency-department crowding from patient counts, bed capacity and waiting-time inputs.
| Input | What it means |
|---|---|
| Total number of beds in ED | The number to test or transform; use the integer or real-number domain stated in the formula. |
| Total number of beds in the hospital | The number to test or transform; use the integer or real-number domain stated in the formula. |
| Total number of the patients in ED | The number to test or transform; use the integer or real-number domain stated in the formula. |
| Critical care patients | Use the observed finding or laboratory value for this criterion, following the definition shown in the form. |
| Number of admits in the ED | The number to test or transform; use the integer or real-number domain stated in the formula. |
| Waiting time of the last admitted patient | Elapsed time or duration in the unit selected on the form. |
| Waiting time of longest waiting room patient | Elapsed time or duration in the unit selected on the form. |
An ED with 40 patients and 20 treatment spaces has a patient-to-space ratio of 2 before the other model terms.
Use the calculation to make the method and its inputs easier to check with a healthcare professional. Its meaning depends on the clinical setting and on whether the underlying method is appropriate for that person.
No. It describes a calculation or score from the supplied information. A qualified clinician must check the measurements, the method’s applicability and the wider clinical picture.
Use the units specified in the form and select a conversion only where the page provides one. Different substances need different conversion factors; a mismatch can produce a plausible but incorrect result.
