Comparison of laboratory and immediate diagnosis of coagulation for patients under oral anticoagulation therapy before dental surgery.

BACKGROUND: Dental surgery can be carried out on patients under oral anticoagulation therapy by using haemostyptic measures. The aim of the study was a comparative analysis of coagulation by laboratory methods and immediate patient diagnosis on the day of the planned procedure. METHODS: On the planned day of treatment, diagnoses were carried out on 298 patients for Prothrombin Time (PT), the International Normalised Ratio (INR), and Partial Thromboplastin Time (PTT). The decision to proceed with treatment was made with an INR < 4.0 according to laboratory results. RESULTS: Planned treatment did not go ahead in 2.7% of cases. Postoperatively, 14.8% resulted in secondary bleeding, but were able to be treated as out-patients. 1.7% had to be treated as in-patients. The average error between the immediate diagnosis and the laboratory method: 95% confidence interval was -5.8 +/- 15.2% for PT, -2.7 +/- 17.9 s for PTT and 0.23 +/- 0.80 for INR. The limits for concordance were 9.4 and -21.1% for PT, 15.2 and -20.5 s for PTT, and 1.03 and -0.57 for INR. CONCLUSION: This study showed a clinically acceptable concordance between laboratory and immediate diagnosis for INR. Concordance for PT and PTT did not meet clinical requirements. For patients under oral anticoagulation therapy, patient INR diagnosis enabled optimisation of the treatment procedure when planning dental surgery.

A practical guide to antibiotic prophylaxis in restorative dentistry.

The purpose of this paper is to review the principles and practicalities of antibiotic prophylaxis in medically compromised patients who require restorative dentistry. Guidelines for the management of patients who are susceptible to infection are given. The importance of oral health and the rational use of both local and systemic antimicrobial prophylaxis is described.

Quality of written reports provided by consultants in restorative dentistry to referring general dental practitioners in the west midlands.

OBJECTIVES: The primary objective of this study was to assess the views of general dental practitioners (GDPs) on the content, style, and readability of written reports provided by restorative consultants at a dental hospital in response to referral letters from the GDPs. The secondary objective was to determine the style of the written consultant report preferred by GDPs. SETTING: Referral letters received and replied to by four consultants in the restorative department at Birmingham Dental Hospital. METHOD: The quality of written reports sent by the four consultants to 100 referring GDPs in the West Midlands area was evaluated using a postal questionnaire, which assessed 100 GDPs' satisfaction with the content, style, and readability of the reports. To assess which format they favoured a second questionnaire was subsequently sent to the same GDPs with three versions of the original report in: (a) a standard format, (b) a summary format, and (c) a bullet point format. RESULTS: The results of the initial questionnaire revealed that 79 (96%) of practitioners were satisfied with the existing style of the reports. Following a second questionnaire in which GDPs were asked to choose which format they preferred, 61 (81%) expressed a preference for a bullet point or summary style report. CONCLUSION: The GDPs who responded to the questionnaires felt that a bullet point format or summary style report from the consultants concerned would summarise cases more clearly and concisely than the conventional standard format letters which they had previously received. Opportunities may exist for improving the quality of consultant reply letters through the use of structured templates and/or a summary or bullet point format.
