[Myringoplasty in chronic simple otitis media. Comparative analysis of underlay and overlay techniques].

Myringoplasty is a surgical procedure that has been routinely performed by otological surgeons for more than 40 years. Underlay and overlay are the most commonly used tympanoplastic techniques. A comparison was made of anatomic and functional results, and the year of intervention, for 97 myringoplasties, 54 using the underlay technique and 43 using the overlay technique. Selection of the overlay or underlay technique was guided by specific indications. Results were evaluated at least 1 year after surgery. No significant differences were found in anatomic success (88.8% for underlay and 97.6% for overlay). Favorable functional results (average gap of 0 to 20 dB for frequencies of 500, 1000, 2000, and 4000 Hz) were obtained in 88.4% of patients treated with the overlay technique and in 83% of those treated with the overlay technique, with no significant difference. We believe that the high percentage of good results was due to careful preoperative selection.

[Detectig errors in chemotherapy prescription].

OBJECTIVE: To analyse errors detected in the prescription of cytostatic drugs. MATERIAL AND METHODS: Prospective study (February 1st to April 15th, 2002). All medical orders containing cytostatic agents were checked and 13 variables were studied: identification, anthropometric data, diagnosis, protocol, number of cycles, cytostatic drug, length of treatment, dose, route of administration, volume of infusion and/or final concentration, infusion time, diluent, and doctor's signature. Several possible errors were identified for each variable. Information on whether it was the first cycle, prescribing service, and prescription format was also recorded. RESULTS: In all, 618 medical orders were reviewed for a total of 1178 lines of cytostatic agents and 2,171 doses. The possible number of errors was 12.101 and the total number of errors actually found was 2,706 (22,03%). Not all these errors had the same impact on patients. Errors by omission were 2,340 (87,77%). Those which nursing staff found difficult to check and/or administer stood at 281 (10,54%). Potentially serious errors numbered 60 (2.06%): wrong body area > 10%: 5; wrong body area 5-10%: 2; erroneus protocol: 2; incorrect volume: 16; wrong dosage: 23 (difference < 25%: 5; difference 10-25%: 14; difference < 10%: 4). Reductions indicated but not implemented: 9; Inappropiate diluent: 3. There were no incorrect or omitted medications. CONCLUSION: The description of such errors and their uantification is a useful method of quality asurance in order to establish appropiate corrective measures. The most common error was the omission of information and therefore this issue, along with the development of computerised prescriptions, should be addressed.
