For collection of information on Admitted Patient Waiting Times, the period of waiting for each PATIENT expressed as completed weeks waiting is required to be calculated in order to determine the appropriate waiting time band the PATIENT should be counted within.

The start point of the waiting period calculation is the ELECTIVE ADMISSION EFFECTIVE WAIT START DATE which takes into consideration any PATIENT instigated resets. The end point is the REPORTING PERIOD END DATE. Once the period of wait has been calculated from these two dates in days, the result is also adjusted for any periods of suspension.

The collection of information may be retrospective and therefore any PATIENT where the ELECTIVE ADMISSION EFFECTIVE WAIT START DATE is after REPORTING PERIOD END DATE should be excluded from the count as they are outside the date boundaries of the collection.

Patients waiting for admission

When an ELECTIVE ADMISSION LIST ENTRY is made for a PATIENT following a DECISION TO ADMIT and the PATIENT accepts an OFFERED FOR ADMISSION DATE of an OFFER OF ADMISSION, it is this offered date that the PATIENT is expected to attend and be admitted. ADMISSION OFFER OUTCOME records whether or not the PATIENT was admitted and the circumstances that applied.

The ELECTIVE ADMISSION LIST ENTRY is removed from the ELECTIVE ADMISSION LIST when the PATIENT is admitted or removed for other specified reasons. ELECTIVE ADMISSION LIST REMOVAL REASON records the method of removal from the list and ELECTIVE ADMISSION LIST REMOVAL DATE records the removal date.

Once removed from the ELECTIVE ADMISSION LIST, the PATIENT ceases to be waiting for admission and all associated OFFERS OF ADMISSION become inactive.

The waiting time band the PATIENT is counted within is calculated from the ELECTIVE ADMISSION EFFECTIVE WAIT START DATE to the REPORTING PERIOD END DATE. The ELECTIVE ADMISSION EFFECTIVE WAIT START DATE is an adjusted date which takes into consideration the effect on waiting time calculations of Self-Deferred Admission.

Periods of suspension which are within the waiting period are also deducted to arrive at the appropriate waiting time band for the PATIENT to be counted within. See Suspended Patient.

ADMISSION OFFER OUTCOME records whether or not the PATIENT was admitted and the circumstances that applied and for cancellations, the date of cancellation is recorded by the OFFER OF ADMISSION cancellation date.

If the ELECTIVE ADMISSION EFFECTIVE WAIT START DATE is after the REPORTING PERIOD END DATE then no waiting time should be calculated and the PATIENT should be excluded from the count as they are outside the date boundaries of the collection.

Calculation of total suspension days

If the PATIENT has been suspended at all during the waiting time period, the period(s) of suspension should be calculated and summed to calculate the total suspension days which will then be deducted from the adjusted calculated days.

However, if the PATIENT is still suspended as at the REPORTING PERIOD END DATE they are excluded from Admitted Patient Stocks counts and no calculation of any periods of suspension is required.

Waiting time bands

The number of days waiting calculated excluding any suspension or self-deferred periods are divided by 7 to give the number of weeks waiting. Where the resultant number is less than 1, the Waiting Time Band is less than 1 week.

For example,

A PATIENT has an ORIGINAL DECIDED TO ADMIT DATE of 4/8/2005.

The hospital offers an admission for 5/9/2005 which the PATIENT accepts.

On the day of the admission the PATIENT has to cancel the admission and so his ELECTIVE ADMISSION EFFECTIVE WAIT START DATE is set to 5/9/2005 (the admission date that was cancelled).

The PATIENT then informs the hospital that he is on holiday for 3 weeks and so cannot come into hospital between 13/9/2005 and 3/10/2005 inclusive so the PATIENT is suspended for that period.

The PATIENT is given an OFFERED FOR ADMISSION DATE of 12/10/2005. This is accepted by the PATIENT and the PATIENT is admitted.

So the number of days the PATIENT was waiting is 37 days (from ELECTIVE ADMISSION EFFECTIVE WAIT START DATE to the day before the OFFERED FOR ADMISSION DATE). The number of days in the suspended period (21 days) is then subtracted from waiting period of 37, which leaves 16 days. This is divided by 7 to give the actual period of weeks waiting as more than 2 weeks and less than 3 weeks.
