We chose the following aspects of patient care to be included in the database form: presurgery patient condition and medications, anesthesia information, perfusion information, surgery information, recovery information, status of the patient at discharge and30 days and 365 days postsurgery follow-up information. Information was collected through structured questionnaire by trained data abstractor and entered into Microsoft Access software. On the basis of research hypotheses, specific data chunk was extracted and analyzed in SPSS (Statistical Package of Social Sciences) software. Impact in clinical practice Before this database, there was no way to monitor mortality and morbidity. Fortunately, with the development of database, postsurgery mortality and morbidity rates could easily be generated. It helped in development of strict enforcement of protocol to reduce the mortality and morbidity rates. It also helped in controlling preventable postsurgery complications. It also helps in identification of a gap inpatient knowledge regarding the use of warfarin after heart valve surgery and deficiencies in laboratory capabilities, both causing catastrophic complications. As a result, we modified our practice in an effort to address these issues and reduce the complication rates after heart valve surgery. Furthermore, identification of the need to quantify the midterm functional status of in-person and telephonic interview, resulting in the development of a questionnaire that has been added to our protocol 1-year postsurgery.
