A survey of awareness, opinion and reported use of clinical practice guidelines (CPG) of the Royal College of Anesthesiologists of Thailand.

BACKGROUND: Up to the present (2006), The Royal College of Anesthesiologists of Thailand (RCAT) has proposed and revised six practice guidelines. For guidelines to achieve their objectives, anyone who gets involved needs to be aware of the guidelines, be able to accept, and adhere to them. Although the authors did introduce their guidelines by several passive means, the authors have not yet ascertained what the result were. OBJECTIVE: The primary objective of the present study was to assess awareness, opinion, limitation, and reported use of guidelines. The secondary objective was to identify factors associated with variation, agreement, and reported use of guidelines. MATERIAL AND METHOD: A cross sectional, self-report survey study was conducted. An anonymous questionnaire including prepaid-addressed reply envelopes was mailed to 600 anesthesiologists and 1,300 nurse anesthetists, nationwide, based on the college's list. The questions covered respondents' general characteristics: awareness, agreement, and reported use of the existing guidelines; opinion on implementation media, which guidelines the members need, their local guidelines, and the impact of guidelines on their practice. All data were extracted and reported using descriptive statistics. Multiple logistic regression was done to identify factors associated with an agreement with and a reported use of the guidelines. RESULTS: The overall response rate was 33.4% and nurse anesthetists had a higher response than anesthesiologists. Forty-six percent of the respondents were aware of the existing guidelines. This result corresponded to percentage of those who had read the guidelines (41%). Among the six existing guidelines, the least two guidelines reported use of and agreement with, were those for labor analgesia and conscious sedation (23-28%, 24-28%). The guidelines for spinal anesthesia received the most response (46%). For respondents who had read the guidelines, most of them (80% to 94%) rated the level of agreement and reported use as good to excellent. The respondents also rated the announcement of the guidelines during the annual meeting of the Royal College of Anesthesiologists of Thailand as the best implementation strategy. Impracticability, inadequate dissemination, and un-cooperation among colleagues were the three most important obstacles of using the guidelines. In addition, the present study demonstrated three significant factors, anesthesiologists, regional hospitals, and general hospitals, as associated with reporting frequent use of and high agreement with the guidelines. CONCLUSION: The low level of awareness and reported use of the present guidelines among the members reflects poor implementation and dissemination. However the present study reveals some information that will guide the authors to introduce intensive and targeted interventions to encourage the members to comply and adhere to the guidelines designed to improve the quality of patients' care.

When should we order preoperative chest radiography: A systematic review and clinical practice guidelines.

Routine preoperative investigation consumes much resource while Thailand suffers severe financial crisis. Objectives of the study were to apply a systematic review to answer the question whether routine preoperative investigation affected health outcomes; and to construct clinical practice guidelines for preoperative chest radiography (CXR). The guidelines were prepared for elective, non-cardiothoracic surgery in adult patients. Methods of the study were Medline search (1980-1998) and search from studies published in Thailand. Criteria for high validity and reliability were applied to paper selection. The results of the systematic review were discussed among anesthesiologists and other specialists and the guidelines were drawn by consensus. Results from the systematic review, there were no randomized controlled trials to answer the question and no studies reported health outcomes. Routine preoperative investigations yielded few positive results and were not very useful for patient care. From this review and the consensus, we proposed the guidelines, which consisted of a history questionnaire, physical examination and indication for investigation. For the preoperative CXR the indications were: age > 45 years, history of cardiovascular and respiratory diseases, autoimmune deficiency syndrome (AIDS), heavy smoking, chronic cough or fever, malignancy and findings of abnormal breath sounds on examination. This study recommends and prefers preoperative CXR as indicated by history and physical examination to routine.

When should we order preoperative electrocardiography: A systematic review and clinical practice guidelines.

Routine preoperative investigation consumes many resources at the time when Thailand is suffering a severe financial crisis. The objectives of the study were to apply a systematic review to answer the question if routine preoperative investigation affects health outcomes; and to construct clinical practice guidelines for preoperative electrocardiography (ECG). The guidelines were prepared for elective, non-cardiothoracic surgery in adult patients. Methods of the study were a Medline search (1980-1998) and a search of studies published in Thailand. Criteria for high validity and reliability were applied to paper selection. The results of the systematic review were discussed among anesthesiologists and other specialists and the guidelines were drawn by consensus. Results from systematic review found that there were no randomized controlled trials to answer the question and no studies reported health outcomes. Routine preoperative investigation yielded few positive results and were not very useful for patient care. From this review and consensus, we proposed the following guidelines: a history questionnaire, physical examination, and indication for investigation. For the preoperative ECG, the indications are: age > 45 years, history of hypertension, heart disease, palpitation or frequent syncope, diabetes, chronic cough for > 3 weeks or pulmonary disease, heavy smoking (> 10 pack /days for> 10 years), radiotherapy or chemotherapy. Preoperative ECG carried out according to these guidelines would be more cost-effective and routine preoperative investigation should be abandoned.
