Objective: to propose three pictorial methods of presenting hospital outcome data, suitable for use in older patients entering medical specialties (including rehabilitation).
Patients: 224 patients (mean age 80.6 years, 56% female, 75% emergencies) admitted to a department of medicine for the elderly.
Presentational techniques: the methods we propose for the presentation of outcome data are (i) place of discharge, using a two-dimensional diagram; (ii) 'survival' analyses, but using discharge from hospital rather than death as the endpoint; and (iii) 'phase diagrams', a novel method of charting the progress of a cohort of patients. To illustrate these methods, the relationship between admission case-mix (with patients put into tertiles on the basis of their Barthel index score) and outcome is shown graphically.
Result: each of the three techniques has different relative strengths, but their pictorial nature allows for rapid interpretation of data, showing, for example, the marked influence of case-mix. Separate analyses of subgroups of patients (such as those who die in hospital and those who survive) are also readily attainable by the three methods.
Conclusions: the three methods of presenting outcome should be of benefit in comparing the performance of different units, particularly when case-mix is taken into account. The pictorial methods are complementary both to more conventional patient-based methods (mean duration of stay, median duration of stay, percentile duration of stay, regression analyses etc) and to modelling techniques using 'census' data from large numbers of patients.
