Patterns of use and satisfaction with a university-based teleradiology system

The effectiveness of service delivery initiatives at improving patients' waiting times in clinical radiology departments: a systematic review

We reviewed the literature for the impact of service delivery initiatives (SDIs) on patients' waiting times within radiology departments. We searched MEDLINE, EMBASE, CINAHL, INSPEC and The Cochrane Library for relevant articles published between 1995 and February, 2013. The Cochrane EPOC risk of bias tool was used to assess the risk of bias on studies that met specified design criteria. Fifty-seven studies met the inclusion criteria. The types of SDI implemented included extended scope practice (ESP, three studies), quality management (12 studies), productivity-enhancing technologies (PETs, 29 studies), multiple interventions (11 studies), outsourcing and pay-for-performance (one study each). The uncontrolled pre- and post-intervention and the post-intervention designs were used in 54 (95%) of the studies. The reporting quality was poor: many of the studies did not test and/or report the statistical significance of their results. The studies were highly heterogeneous, therefore meta-analysis was inappropriate. The following type of SDIs showed promising results: extended scope practice; quality management methodologies including Six Sigma, Lean methodology, and continuous quality improvement; productivity-enhancing technologies including speech recognition reporting, teleradiology and computerised physician order entry systems. We have suggested improved study design and the mapping of the definitions of patient waiting times in radiology to generic timelines as a starting point for moving towards a situation where it becomes less restrictive to compare and/or pool the results of future studies in a meta-analysis.

University-Based Teleradiology in the United States

This article reviews the University of Arizona's more than 15 years of experience with teleradiology and provides an overview of university-based teleradiology practice in the United States (U.S.). In the U.S., teleradiology is a major economic enterprise with many private for-profit companies offering national teleradiology services (i.e., professional interpretation of radiologic studies of all types by American Board of Radiology certified radiologists). The initial thrust for teleradiology was for after-hours coverage of radiologic studies, but teleradiology has expanded its venue to include routine full-time or partial coverage for small hospitals, clinics, specialty medical practices, and urgent care centers. It also provides subspecialty radiologic coverage not available at smaller medical centers and clinics. Many U.S. university-based academic departments of radiology provide teleradiology services usually as an additional for-profit business to supplement departmental income. Since academic-based teleradiology providers have to compete in a very demanding marketplace, their success is not guaranteed. They must provide timely, high-quality professional services for a competitive price. Academic practices have the advantage of house officers and fellows who can help with the coverage, and they have excellent subspecialty expertise. The marketplace is constantly shifting, and university-based teleradiology practices have to be nimble and adjust to ever-changing situations.

Mapping turnaround times (TAT) to a generic timeline: a systematic review of TAT definitions in clinical domains

BACKGROUND

Assessing turnaround times can help to analyse workflows in hospital information systems. This paper presents a systematic review of literature concerning different turnaround time definitions. Our objectives were to collect relevant literature with respect to this kind of process times in hospitals and their respective domains. We then analysed the existing definitions and summarised them in an appropriate format.

METHODS

Our search strategy was based on Pubmed queries and manual reviews of the bibliographies of retrieved articles. Studies were included if precise definitions of turnaround times were available. A generic timeline was designed through a consensus process to provide an overview of these definitions.

RESULTS

More than 1000 articles were analysed and resulted in 122 papers. Of those, 162 turnaround time definitions in different clinical domains were identified. Starting and end points vary between these domains. To illustrate those turnaround time definitions, a generic timeline was constructed using preferred terms derived from the identified definitions. The consensus process resulted in the following 15 terms: admission, order, biopsy/examination, receipt of specimen in laboratory, procedure completion, interpretation, dictation, transcription, verification, report available, delivery, physician views report, treatment, discharge and discharge letter sent. Based on this analysis, several standard terms for turnaround time definitions are proposed.

CONCLUSION

Using turnaround times to benchmark clinical workflows is still difficult, because even within the same clinical domain many different definitions exist. Mapping of turnaround time definitions to a generic timeline is feasible.

Telemedicine consultation for patients with upper extremity disorders is reliable

Telemedicine is a valuable resource for the delivery of health care to patients in underserved areas. The purpose of this study was to assess the reliability of asynchronous teleconsultation in the diagnosis and establishment of treatment plans for patients with disorders of the upper extremity. One hundred patients with disorders of the upper extremity were prospectively evaluated. Initial patient evaluations, done by an independent evaluator, involved a medical history, physical examination, digital images of the patient, and digitized radiographic studies. This patient information was presented electronically to two hand surgeons 6 months after one surgeon independently evaluated the patients in the outpatient clinic. The physicians formulated diagnosis and treatment plans for the patients based on the blinded electronic information. These findings then were compared with the treatment plans made by the physicians at the time of the patients' visits. Telemedicine consultation resulted in excellent agreement within observers (kappa = .92) and between observers (kappa = .86). Telemedicine consultation seems to be a reliable method for diagnosis and establishment of treatment plans in the management of upper extremity disorders.

LEVEL OF EVIDENCE

Diagnostic study, Level I-1 (testing of previously developed diagnostic criteria in series of consecutive patients--with universally applied reference gold standard). See the Guidelines for Authors for a complete description of levels of evidence.

High-volume teleradiology service: focus on radiologist satisfaction

In 1998 we surveyed our radiologists on teleradiology satisfaction. Results were generally positive. In 2002 we experienced a sevenfold case increase in teleradiology volume. The present study surveyed the radiologists again. The hypothesis was that, with increased case volume and radiologist experience with the system, ratings would increase. Image quality was excellent/good, although plain film and ultra sound (US) had more fair/poor ratings. Monitors, navigation, image processing, and Web-based reporting were rated as excellent/good. The voice-recognition system was rated poorly. Diagnostic confidence was about the same as for film. Exceptions were magnetic resonance imaging (MRI) US, and plain film. Up to 10% of cases are unreadable because of poor image quality, not enough images, or inadequate patient history. Overall, the radiologists are satisfied, although some improvements can be made.

Internet based consultations to transfer knowledge for patients requiring specialised care: retrospective case review

OBJECTIVE

To assess whether transferring knowledge from specialists at centres of excellence to referring doctors through online consultations can improve the management of patients requiring specialised care.

DESIGN

Retrospective case review of the first year of internet based patient initiated consultations between referring doctors and consulting specialists.

SETTING

US teaching hospitals affiliated with an organisation providing internet based consultations.

PARTICIPANTS

Doctors in various settings around the world engaging in internet based consultations with specialists.

MAIN OUTCOME MEASURES

New recommendations for treatment, change in diagnosis, and turnaround time for consultation compared with time to see a specialist.

RESULTS

79 consultations took place. 90% (n=71) of consultations were for services related to oncology. 90% of consultations involved new recommendations for treatment. The most common recommendation was a new chemotherapeutic regimen (68%, n=54). Diagnosis changed in 5% (n=4) of cases. The average turnaround time was 6.8 working days compared with an average of 19 working days to see a comparable specialist.

CONCLUSIONS

Internet based consultations between specialists at centres of excellence and referring doctors contribute to patient care through recommendations for new treatment and timely access to specialist knowledge. Although change in diagnosis occurred in only a few cases, the prognostic and therapeutic implications for these patients may be profound.

Teleradiology in orthopaedic surgery: impact on clinical decision making for acute fracture management

OBJECTIVE

To determine whether teleradiology improved clinical decision making for the treatment of patients with acute fractures.

DESIGN

Prospective cohort.

SETTING

Level 1 trauma center.

PATIENTS

One-hundred eight consecutive patients with 123 acute fractures who visited our Level 1 trauma center, when the first author was the attending orthopedic surgeon on call, and had orthopaedic consultations were included.

MAIN OUTCOME MEASURES

In each case, an orthopaedic junior resident performed the emergency department consultation. Radiographs were digitized and electronically transmitted to the attending orthopaedist. Treatment plans were formulated and recorded by the attending surgeon at three different times. The original plan was defined after traditional verbal communication of physical and radiographic findings. A revised plan was defined after the radiographic images were reviewed by the attending surgeon, and the final plan was defined after review of the original radiographs. Two different types of deviations from the original plan were distinguished. Changes in the acute management were defined as any emergency department procedures, emergent operative procedures, or dispositions that were not part of the original plan. Changes in the ultimate management were defined as changes to the original plan that did not affect emergency department treatment, emergent operative procedures, or the disposition of the patient.

RESULTS

In twenty-six of the 123 fractures (21 percent), the additional information provided by viewing electronically transmitted images of radiographs changed the acute management or the ultimate management. In none of the 123 cases did subsequent review of original radiographs result in any further changes to the treatment plan.

CONCLUSIONS

The routine use of electronically transmitted digitized radiographic images has the potential to improve clinical decision making for the care of patients with acute fractures.
