Qualitative assessment of telemedicine network and computer-based telecolposcopy

Telemedical cervical cancer screening to bridge medicaid service care gap for rural women

BACKGROUND

The Arkansas Medicaid program for low-income women provides cervical cancer screening, in the form of Pap smears, and treatment but no diagnostic means of bridging the two, such as a procedure called "colposcopy." Telemedicine offers a viable means to bridging this gap. Previously telecolposcopy has been used in small demonstration projects as a means to deliver colposcopy services to at-risk rural populations at a comparable quality to in-person colposcopy.

SUBJECTS AND METHODS

The University of Arkansas for Medical Sciences' Antenatal & Neonatal Guidelines, Education and Learning System Program and Center for Distance Health developed an innovative collaborative telemedicine pilot program with the Arkansas Department of Health that used both specialty physician oversight and nurse examiners. Underserved rural patients from the Department of Health were provided with colposcopy services via interactive telemedicine at four separate spoke sites. During each weekly 3-h clinic, an advanced practice nurse/nurse practitioner at each of the spoke sites performed the exams and collected biopsy specimens under the real-time, interactive supervision of an experienced faculty member at the hub site.

RESULTS

Between January 1, 2010 and June 21, 2011, the program scheduled 1,812 visits, involving 1,504 unduplicated patient referrals from 68 of Arkansas's 75 counties, and performed 1,298 telecolposcopic exams.

CONCLUSIONS

This project provides complex specialty gynecological services using telemedicine technology to overcome geographic barriers to care while producing results comparable to traditional examinations. It is cost-effective and well received by patients and can be used as a model for improving access to care among vulnerable populations.

Three principles for determining the relevancy of store-and-forward and live interactive telemedicine: reinterpreting two telemedicine research reviews and other research

The Agency for Healthcare Research and Quality sponsored two telemedicine research reviews. The latest review concluded that telemedicine is most relevant to specialties, such as psychiatry and neurology, where high levels of patient interaction are crucial to assessment. Telemedicine research studies cited in the reviews having positive findings in the specialties of ophthalmology, otolaryngology, obstetrics and gynecology, gastroenterology, and cardiology and more recent research in these areas are reviewed to identify criteria other than degree of interaction for determining the appropriateness of telemedicine interventions. These criteria include congruity or the extent that procedures used in telemedicine are similar to those of in-person examination, fidelity or the degree to which the information used for assessment in remote examinations is of similar quality to that used in-person, and reliability or the consistency with which information can be gathered and transmitted.

Digital colposcopy: ready for use? An overview of literature

The aims of this review were to summarise the various methods of digital colposcopy and to provide an overview of their efficacy. We conducted a literature search and focused on papers that described a technique for colposcopy, other than conventional colposcopy, and compared this with conventional colposcopy and/or histology and included digitalisation of the process. All papers have been classified in one of the following categories: digital imaging and telecolposcopy, spectroscopy, computerised colposcopy, optical coherence tomography and confocal microcolposcopy. Among the most promising developments is spectroscopy, allowing a more or less automated analysis and interpretation of the colposcopic image.

Telemedicine Network Telecolposcopy Compared with Computer-Based Telecolposcopy

OBJECTIVES

To compare computer-based telecolposcopy with telemedicine network telecolposcopy.

MATERIALS AND METHODS

An on-site expert and local clinician at two rural sites conducted colposcopic examinations on 264 women. Colposcopic images were captured and transmitted to two other experts at a remote location using a statewide telemedicine system and a computer and modem-based system. Sensitivity and specificity, agreement of examination adequacy and management, effects of delayed interpretations, and costs were compared for each system.

RESULTS

A greater rate of satisfactory colposcopy results was reported by the telemedicine network (66.1%) compared with computer-based (43.6%) telecolposcopy (p < .0001). Greater rates of cervical biopsy (p = .005) and endocervical curettage (p = .03) were required by delayed telecolposcopy compared with immediate telecolposcopic services. There were no significant differences in sensitivity of detecting cervical neoplasia among the types of the telecolposcopy. Computer-based telecolposcopy cost 28 dollars less per patient than telemedicine network telecolposcopy.

CONCLUSIONS

Computer-based telecolposcopy may be a reasonable, cost-effective adjunct to on-site colposcopy for evaluating women in medically underserved areas. Synchronous telecolposcopic examination minimizes histologic sampling and improves consultation.
