Three software complexity measures (Halstead's E, McCabe's u(G), and the length as measured by number of statements) were compared to programmer performance on two software maintenance tasks. In an experiment on understanding, length and u(G) correlated with the percent of statements correctly recalled. In an experiment on modification, most significant(More)
During recent years, there have been many a t tempts to define and measure the "complexity" of a computer program.

A within-subjects experimental design was used to test the effect of two variables on program understanding. The independent variables were complexity of control flow and paragraphing of the source code. Understanding was measured by having the subjects memorize the code for a fixed time and reconstruct the code verbatim. Also some subjects were asked to(More)
AIMS The aims of this study were to measure baseline use of Ottawa ankle rules (OAR), validate the OAR and, if appropriate, explore the impact of implementing the Rules on X-ray rates in a primary care, after hours medical centre setting. METHODS General practitioners (GPs) were surveyed to find their awareness of ankle injury guidelines. Data concerning(More)
AIMS To describe patterns of variation in referral among general practitioners, and to establish whether variability among practitioners within a geographic area is associated with high levels of utilisation in an area. METHOD Multilevel analysis of routinely collected primary care data. The four outcome measures were referral to physiotherapy, specialist(More)
OBJECTIVES To explore the attitudes of clinicians working in New Zealand publicly funded hospitals towards prioritizing patients for elective surgery, and their reported use of clinical priority assessment criteria (CPAC).
