Hospitals have undertaken quality improvement (QI) efforts to address patient care deficiencies and improve hospital systems. Identifying system defects and devising better ways to do things can be challenging. An effective QI program can improve clinical activity [1]. Many hospitals are actively engaged in improvement efforts, but these activities vary in method and impact. Hospitals follow trends that set QI as a new strategic priority, employ quality practices consistent with aims, strengthen staff training and involvement in QI methods, and engage an ar ray of QI activities and clinical QI strategies. Postoperative pain is an important complication encountered after surgery. With its capacity for self-adjustability, intravenous patient-controlled analgesia (IV-PCA) use in controlling postoperative pain has become widespread [2]. This can reduce hospitalization time by facilitating recovery and promoting wound healing. However, discontinuing IV-PCA due to any side effects leads to patient dissatisfaction and resource waste. In our hospital, each health care system unit makes an effort to improve its processes in cooperation with the QI department. The anesthesia and post-anesthesia care unit nurse team focused on PCA problems, and planned to improve patient PCA satisfaction in response to QI. Two hundred and forty nine patients, ASA I or II, aged 20–60 years, with no history of fentanyl and ondansetron side effects who had IV-PCA after abdominal general surgery, were included in this study. Patients supplied informed consent. Patients with major organ diseases, or who were pregnant or allergic to fentanyl or ondansetron, were excluded. Patients did not receive premedication. General anesthesia was induced with propofol 1.5–2 mg/kg and rocuronium 0.8 mg/kg, and maintained with sevoflurane 1.5–3 vol%, O2-N2O 3 L/min (FIO2 0.5). Standard monitoring (ECG, non-invasive blood pressure and pulse oximetry) was established during anesthesia. When surgery was finished, muscle relaxation was reversed by glycopyrrolate with pyridostigmine administration. Other antiemetics were not used during and after anesthesia, except for ondansetron mixed in the IV-PCA. The IV-PCA basal rate was 2 ml/h, bolus injection was 2 ml, lockout time was set to 15 min. IV-PCA was connected 10 min before the end of surgery. In the first survey, all the patients had IV-PCA, including fentanyl 1,500 μg and ondansetron 4 mg with normal saline (total 100 ml), regardless of patient body weight or surgery type. Discontinuation after PCA was 20.5%. The reasons for removing IV-PCA were postoperative nausea and vomiting (PONV) (64.7%), pain resolution (11.7%), dizziness (11.7%), and early discharge (1.9%). The QI anesthesia nurse team worked with anesthesiologists and took several steps to decrease PCA discontinuation rate. First, fentanyl dose was planned according to surgery type and patient body weight to reduce side effects: 15–20 μg/kg for major surgery (ex. gastrectomy) and 10–15 μg/kg for minor surgery (ex. appendectomy, laparoscopic cholecystectomy). Second, ondansetron was increased from 4 mg to 12 mg. Third, patients were educated more intensively to convey that IV-PCA is not a complete solution to pain relief, but that it can largely reduce pain. They were also informed about possible side effects and their management.
