“…At the same time, the introduction of a digital microscope would likely be accompanied by requirements in relation to lighting levels, as has been the case in radiology, in order to prevent reflection and glare and to reduce fatigue, both of which have the potential to negatively impact efficiency and accuracy (Goyal et al 2009). Although such requirements are important, the need to sit in a darkened room may act as a real barrier to the introduction of digital pathology.…”

Diagnosis at the microscope: a workplace study of histopathology

et al. 2011

Histopathologists diagnose cancer and other diseases by using a microscope to examine glass slides containing thin sections of human tissue. Technological advances mean that it is now possible to digitise the slides so that they can be viewed on a computer, promising a number of benefits in terms of both efficiency and safety.Despite this, uptake of digital microscopy for diagnostic work has been slow and research suggests scepticism and uncertainty amongst histopathologists. In order to design a successful digital microscope, one which fits with the work practices of histopathologists and which they are happy to use within their daily work, we have undertaken a workplace study of a histopathology department. In this paper, we present the findings of that study and discuss the implications of these findings for the design of a digital microscope. The findings emphasise the way in which a diagnosis is built up as particular features on the glass slides are noticed and highlighted and the various information sources that are drawn on in the process of making a diagnosis.

“…As such, optimal use of PACS is of great importance to ensure an efficient workflow, and consequently numerous research studies have been dedicated to this matter albeit predominately focused on external elements related to PACS. For example, studies have evaluated the effect of different input devices on radiologists' efficiency [1][2][3], impact of employed display devices [4], or general ergonomic and environmental aspects of the reading context [5][6][7][8]. A very limited set of research studies [9][10][11][12] have focused directly on PACS usage itself.…”

Factors Affecting Radiologist’s PACS Usage

The purpose of this study was to determine if any of the factors radiologist, examination category, time of week, and week effect PACS usage, with PACS usage defined as the sequential order of computer commands issued by a radiologist in a PACS during interpretation and dictation. We initially hypothesized that only radiologist and examination category would have significant effects on PACS usage. Command logs covering 8 weeks of PACS usage were analyzed. For each command trace (describing performed activities of an attending radiologist interpreting a single examination), the PACS usage variables number of commands, number of command classes, bigram repetitiveness, and time to read were extracted. Generalized linear models were used to determine the significance of the factors on the PACS usage variables. The statistical results confirmed the initial hypothesis that radiologist and examination category affect PACS usage and that the factors week and time of week to a large extent have no significant effect. As such, this work provides direction for continued efforts to analyze system data to better understand PACS utilization, which in turn can provide input to enable optimal utilization and configuration of corresponding systems. These continued efforts were, in this work, exemplified by a more detailed analysis using PACS usage profiles, which revealed insights directly applicable to improve PACS utilization through modified system configuration.

“…It has been shown that increased use of technology, i.e. PACS [6] and voice recognition software [7], and ergonomics [8] can increase reporting productivity. The focus of the efficiency is moving into the consultant contract, productivity and value for money.…”

Increasing workloads and the current austerity measures are putting UK radiology departments under considerable stress. We need to look at the most efficient ways to manage radiology departments in order to cope with increasing demand. Consequently, a system is needed that can compare productivity between radiologists with different jobs. We measured workload in a UK radiology department and compared the productivities of consultants working different numbers of sessions, which are called programmed activities (PAs), to identify the optimal job plan structure for reporting productivity. Reporting data was gathered from electronic records for 14 consultants working different numbers of PA during the period April 2010-March 2011. These were converted into relative value unit (RVU) scores using a modified RCSI RVU system. Crude and net workloads were calculated for each consultant by dividing their total RVU score by the number of PAs they were contracted for and how many they spent reporting. The consultants reported 118,001 imaging studies. There was statistically significant variation in productivity between consultants working different numbers of PAs on χ 2 analysis (p<0.05). Consultants working 12 PAs were more productive than consultants working 11 PAs, with net workloads of 7636 RVU/PA/year versus net 6146 RVU/PA/ year, p<0.05. Although UK consultants working 12 PAs per week are more productive than their colleagues, the reasons why are unclear. We have identified a method that can be developed further to identify efficient working practices in UK radiology departments. However, a UK-specific RVU system would make this productivity analysis more accurate.
