Comparison of teleconsultations and face-to-face consultations: preliminary results of a United Kingdom multicentre teledermatology study.

The objective of this multicentre study was to undertake a systematic comparison of face-to-face consultations and teleconsultations performed using low-cost videoconferencing equipment. One hundred and twenty-six patients were enrolled by their general practitioners across three sites. Each patient underwent a teleconsultation with a distant dermatologist followed by a traditional face-to-face consultation with a dermatologist. The main outcome measures were diagnostic concordance rates, management plans and patient and doctor satisfaction. One hundred and fifty-five diagnoses were identified by the face-to-face consultations from the sample of 126 patients. Identical diagnoses were recorded from both types of consultation in 59% of cases. Teledermatology consultations missed a secondary diagnosis in 6% of cases and were unable to make a useful diagnosis in 11% of cases. Wrong diagnoses were made by the teledermatologist in 4% of cases. Dermatologists were able to make a definitive diagnosis by face-to-face consultations in significantly more cases than by teleconsultations (P = 0.001). Where both types of consultation resulted in a single diagnosis there was a high level of agreement (kappa = 0.96, lower 95% confidence limit 0.91-1.00). Overall follow-up rates from both types of consultation were almost identical. Fifty per cent of patients seen could have been managed using a single videoconferenced teleconsultation without any requirement for further specialist intervention. Patients reported high levels of satisfaction with the teleconsultations. General practitioners reported that 75% of the teleconsultations were of educational benefit. This study illustrates the potential of telemedicine to diagnose and manage dermatology cases referred from primary care. Once the problem of image quality has been addressed, further studies will be required to investigate the cost-effectiveness of a teledermatology service and the potential consequences for the provision of dermatological services in the U.K.

Measuring cervical ectopy: direct visual assessment versus computerized planimetry.

OBJECTIVE: Cervical ectopy has been identified as a possible risk factor for heterosexual transmission of human immunodeficiency virus. To accurately assess the importance of cervical ectopy, methods for measuring ectopy with precision need to be developed. The objective of this study was to evaluate the reliability of two methods of measuring cervical ectopy: direct visual assessment and computerized planimetry. STUDY DESIGN: Cervical photographs of 85 women without cervical disease were assessed for cervical ectopy by three raters using direct visual assessment and a computer planimetry method. Agreement between the two methods, among the three raters, and among measurements by each rater over time was calculated with use of intraclass correlation coefficients, where 1.0 represents perfect agreement and 0 represents no agreement except by chance. RESULTS: The intraclass correlation coefficient among the three raters (interrater agreement) was 0.58 for direct visual assessment without application of acetic acid to the cervix compared with 0.72 for direct visual assessment with acetic acid and 0.82 for computerized planimetry with acetic acid. The intraclass correlation coefficient among measurements by each rater over time (intrarater agreement) was 0.66 for direct visual assessment without acetic acid compared with 0.77 for direct visual assessment and 0.83 for computerized planimetry after application of acetic acid. When acetic acid was used, the intraclass correlation coefficient between the two methods was 0.69. CONCLUSIONS: Computerized planimetry of cervical photographs may provide the most consistent estimate of the percent of ectopy. However, if time and resources make the use of computer planimetry difficult, direct visual assessment after application of 5% acetic acid appears to provide comparable estimates.

Correction of acidosis in CAPD decreases whole body protein degradation.

Correction of acidosis in CAPD decreases protein degradation and synthesis but has no effect on leucine oxidation. The effect of the correction of metabolic acidosis in CRF patients treated with CAPD was determined from the kinetics of infused L-[1-13C]leucine. Seven CAPD patients were studied before (acid) and after correction of acidosis (bicarbonate) (pH:acid 7.39 +/- 0.01, bicarbonate 7.41 +/- 0.01, P = 0.005). Leucine appearance from body protein (PD) [corrected] and leucine disappearance into body protein (PS) [corrected] decreased significantly with correction of acidosis. (PS: acid 211.7 +/- 9.8, bicarbonate 142.3 +/- 4.2 micromol x kg-1 x hr-1, P < 0.001; PD: acid 200.6 +/- 8.5, bicarbonate 132.4 +/- 3.7 micromol x kg-1 x hr-1, P < 0.001). There was no significant change in leucine oxidation or plasma amino acid concentrations. These results demonstrate that optimal correction of acidosis in CAPD is beneficial in terms of protein turnover.

A pilot study to determine the cost efficiency of a standard parenteral feeding regimen.

This pilot study was initiated to investigate methods designed to reduce the cost of a total parenteral nutrition (TPN) regimen. Seven patients at the Western General Hospital Edinburgh (WGH) were placed on a standard modified TPN regimen where the total fat, nitrogen and energy content of the regimen was reduced. The nutritional status of each patient was monitored prior to and on completion of TPN. Five out of seven patients lost weight. All of the patients exhibited a rise in plasma alkaline phosphate levels demonstrating possible fatty infiltration of the liver. It is concluded that further research is required to test if there is an ideal 'standard' regimen. It may be that such an entity does not exist and a compromise of two regimens may be necessary.
