The aim of this study was to assess the acceptability, validity and reliability of the Short Form 36 quality of life questionnaire in 166 adult patients following discharge from a general intensive care unit. Reliability was quantified by measuring internal consistency using correlation among items and Cronbach's alpha coefficient. Reliability coefficients(More)
The Short Form 36 was used to compare critically ill patients' premorbid quality of life with normal values and investigate any changes following 6 months convalescence. One hundred and sixty-six survivors completed the Short Form 36 at discharge from intensive care. The answers given by survivors were significantly lower than normal for all dimensions.(More)
This study aimed to compare the very long-term survival of critically ill patients with that of the general population, and examine the association among age, sex, admission diagnosis, APACHE II score and mortality. In a retrospective observational cohort study of prospectively gathered data, 2104 adult patients admitted to the intensive care unit (ICU) of(More)
Intensive care is one of the most costly areas of hospital care. Unfortunately, because of the diversity of case mix, costing intensive care is difficult. Many described costing methods previously are limited by being cumbersome, laborious to apply and expensive. The aim of this study was to develop a method for costing intensive care which can be applied(More)
Using average number of patients expected in a year, average length of stay and a target occupancy level to calculate the number of critical care beds needed is mathematically incorrect because of nonlinearity and variability in the factors that control length of stay. For a target occupancy in excess of 80%, this simple calculation will typically(More)
OBJECTIVES 1. To identify generic and disease specific measures of impairment, functional status and health-related quality of life that have been used in adult critical care (intensive and high-dependency care) survivors. 2. To review the validity, reliability and responsiveness of the measures in adult critical care survivors. 3. To consider the(More)
Drug prescription errors are a common cause of adverse incidents and may be largely preventable. The incidence of prescription errors in UK critical care units is unknown. The aim of this study was to collect data about prescription errors and so calculate the incidence and variation of errors nationally. Twenty-four critical care units took part in the(More)
Sir: There are a number of important general principles raised by Dr. MacKenzie’s [1] contribution. The first concerns unbiased and even discussion of the subject matter. Dr. MacKenzie’s concluding paragraph is an excessively biased and unreasonable claim supported by selective data presentation. Many of his criticisms of the PROWESS trial have already been(More)
The aim of this study was to determine the reliability and validity of relatives' assessment of patients' quality of life and to measure the agreement between patients' and relatives' responses to the Short Form 36 quality of life questionnaire, at discharge from and 6 months following intensive care treatment. Ninety-nine patient-relative pairs were(More)
