As a first step Black will conduct the largest study of errors in British hospitals – and expand his work to 34 NHS trusts – to check that his finding that 5% of patients died needlessly.
In this large study, only 56.2% of 4238 prescriptions written had no reported errors.
In a large Ontario study of over 1000 patients, errors were detected in approximately 7% of cases, and multivariate analyses showed that the error rate was independent of time of year, experience of the oncologist, or of a postresidency fellow being involved in the case.
Therefore, we would prefer a large study as standard with considerably smaller amount of random error than the great majority of real epidemiological studies.
4 Patient symptoms are often indicators of the amount of harm arising from healthcare, 1 with retrospective medical record review studies detailing a large rate of errors of commission and omission; many causing AEs. 5 6 While a very low percentage of patients with AEs initiate a formal complaint, significant numbers (23 50%) report concerns related to an AE or undesirable events.
A large study from two tertiary care hospitals reported the error rate was highest in medical ICUs (19.4 per 100 patient days), particularly at the prescribing stage, which accounted for 56% of errors detected [ 1].
Therefore, studies relying on very small definitions of neighborhoods may incur larger amounts of error than those utilizing larger buffers or census tracts.
The sample size was calculated on the premise that 50% of the sample would desire to have children (the key outcome of the overall larger study), with an acceptable sampling error of 5% and at 95% level of confidence.
