  • In total, 34,150 patients for whom English commissioners are responsible completed their Direct Access Audiology RTT pathway during April 2011. Of these, the average (median) waiting time was 4.7 weeks, the 95th percentile waiting time was 14.0 weeks and 98.9% were seen within 18 weeks.
  • At the end of April 2011, 55,349 patients were awaiting Direct Access Audiology treatment. Of these, the average (median) waiting time was 4.2 weeks and the 95th percentile was 13.3 weeks.
  • St George’s Healthcare NHS Trust failed to submit any Direct Access Audiology RTT incomplete pathway data this month.
  • Table 1 shows average (median) waiting times, 95th percentile waiting times and the percentage of patients whose Direct Access Audiology RTT pathway was completed within 18 weeks by SHA. Table 2 shows Direct Access Audiology RTT waiting time trends from October 2008 to April 2011 for completed and incomplete pathways.

Notes to editors

Statistical Notes

1. Direct Access Audiology Referral to Treatment (RTT) times

Direct Access Audiology (DAA) RTT data is collected from NHS providers (NHS Trusts and other providers) and signed off by commissioners (Primary Care Trusts).

The data collection is in two parts:

Part 1 – Completed pathways

Part 2 – Incomplete pathways

The return includes all patients whose RTT clock stopped at any point in the reporting period. A column has been provided to enter data for patients whose length of DAA RTT period is unknown, i.e. patients who have had a clock stop during the month but where the clock start date is not known.

2. Provider and Commissioner based data

Commissioner based returns reflect data on a responsible population basis, which is defined as:

· all those patients resident within the PCT boundary; plus

· all patients registered with GPs who are members of the PCT, but are resident in another PCT; minus

· All patients resident in the PCT, but registered with a GP who is a member of another PCT

Provider based returns cover patients for whom English commissioners are responsible.

3. Average (median) and 95th percentile waiting times

The median is the mid-point of the waiting times distribution (i.e. the 50th percentile) and can be interpreted by saying that 50% of all patients, whose RTT clock stopped during the month, were treated within this time.

The 95th percentile is another statistical measure of the waiting time distribution. It can be interpreted by saying that 95% of patients, whose clock stopped during the month, were treated within this time with one in twenty patients waiting longer than this time for treatment.

It should be noted that medians and percentiles times are calculated from aggregate data, rather than patient level data, and therefore are only estimates of the position on average waits.
