Measurement of radiologist reporting times: Assessment of precision, comparison of three different measurement techniques and review of potential applications.

Introduction: Radiologist reporting times are a key component of radiology department workload assessment, but reliable measurement remains challenging. Currently, there are three contenders for this task: median reporting times (MRTs), extracted directly from a department's radiology information system (RIS); study-ascribed times (SATs), using published tables of individual descriptors derived from a combination of measurement and consensus; and radiology reporting figures (RRFs), using published tables of measured times based on modality and numbers of anatomical areas.

Methods: We review these techniques, their possible uses and some potential pitfalls.

The medial breast margin sign: A new sign of pectus excavatum in adult females and comparison with classic signs.

Introduction: Pectus excavatum (PX) denotes a concavity of the sternum and is the most common chest wall deformity. Many characteristic signs have been described on frontal chest radiographs including increased density of the inferomedial right lung, blurring of the right heart border, steeply angled anterior ribs, horizontal posterior ribs, straight or convex left heart border and loss of silhouette of the descending thoracic aorta. These signs are often subtle and rarely all present in any individual.

Measuring radiologist workload: Progressing from RVUs to study ascribable times.

Introduction: The need to measure reporting workload in teaching departments remains a current pertinent need. In Australia, the Pitman-Jones reporting RVUs have been in the public domain since 2003 (revised in 2009). These are expressed in arbitrary units.

Mastoid pneumocoele with skull base and cervical spine pneumatisation.

Very uncommonly, Eustachian tube dysfunction can lead to symptomatic chronic elevation of middle ear pressure with aeration of bone and adjacent structures in the skull base and upper cervical spine, and an increased risk of fracture. We present a case demonstrating the natural history of this condition over 11 years before treatment and 10 months after treatment.

Measuring and managing radiologist workload: measuring radiologist reporting times using data from a Radiology Information System.

Introduction: Historically, there has been no objective method of measuring the time required for radiologists to produce reports during normal work. We have created a technique for semi-automated measurement of radiologist reporting time, and through it produced a robust set of absolute time requirements and relative value units for consultant reporting of diagnostic examinations in our hospital.

Methods: A large sample of reporting times, recorded automatically by the Radiology Information System (COMRAD, Software Innovations, Christchurch, New Zealand) along with the description of each examination being reported, was placed in a database.

Measuring and managing radiologist workload: a method for quantifying radiologist activities and calculating the full-time equivalents required to operate a service.

Introduction: Accurate and transparent measurement and monitoring of radiologist workload is highly desirable for management of daily workflow in a radiology department, and for informing decisions on department staffing needs. It offers the potential for benchmarking between departments and assessing future national workforce and training requirements. We describe a technique for quantifying, with minimum subjectivity, all the work carried out by radiologists in a tertiary department.

Measuring and managing radiologist workload: application of lean and constraint theories and production planning principles to planning radiology services in a major tertiary hospital.

Introduction: We describe how techniques traditionally used in the manufacturing industry (lean management, the theory of constraints and production planning) can be applied to planning radiology services to reduce the impact of constraints such as limited radiologist hours, and to subsequently reduce delays in accessing imaging and in report turnaround.

Methods: Targets for imaging and reporting were set aligned with clinical needs. Capacity was quantified for each modality and for radiologists and recorded in activity lists.
