背景　研究倡導以運動改善代謝症候群對健康的威脅。本院啟動「健康促進運動計畫」，聚焦於代謝症候群高危險群之初級預防，參與者必須連續使用「運動腳踏車機」達六個月完訓，計畫初期平均使用率達75%，但逐年下降至34.7%，且計畫中斷率達24.3%，引發專案改善動機。目的　藉由增加轉介收案數、降低參與者中斷率，以提高腳踏車機之使用率，達到健康促進之目標。方法　實地調查成功完訓和半途中斷的阻礙因子，分析要因為設備、環境、病友及政策因素，擬定改善策略包括加裝隔熱窗簾、換腳踏車機型、營造宜人環境、訂定運動契約及加強行銷與轉介等。結果　經三個月努力後，腳踏車機使用率提升至77.8%，改善率達124%，收案數明顯增加且中斷率下降至4.8%，後續追蹤呈現持續改善成效。結論　本專案小組成功促使更多病友投入健康促進運動計畫，提高運動腳踏車機使用率，降低運動計畫中斷率，同時明顯改善病人原有的危險因子，達到預防代謝症候群之成效，有效改善運動計畫之整體效益。

Background & Problem: Research has shown that exercise helps reduce the risk and the severity of metabolic syndrome. Since 2009, KMHK hospital has implemented a primary-prevention health promotion program that targets individuals who are at elevated risk of metabolic syndrome. The program engages participants in an exercise protocol that asks them to exercise regularly on a stationary bike three times a week for six months. The utilization rate of the stationary bikes averaged 75% in 2010, but reduced to 34.7% in 2011, with an average withdrawal rate of 24.3%. Therefore, an action team was assembled in order to enhance the effectiveness of the program. Purpose: This project used two primary strategies to increase the utilization of stationary bikes. These strategies included: increasing referrals and decreasing withdrawals. Methods: Surveys of participants who, respectfully, failed to complete and successfully completed the exercise protocol were conducted to identify the factors associated with non-completion / completion. The enrollment policies, the equipment, and the environment were inspected comprehensively. After identifying the causes and effects, several interventions were implemented. These interventions included: installing insulation curtains to block direct sunlight, upgrading the stationary bikes to newer models, creating an environment more conducive to exercise, promoting the referral policies, marketing the health promotion program, and securing family support. Results: After three months, the utilization rate of stationary bikes increased to 77.8%, representing an improvement rate of 124%. Furthermore, the number of case referrals significantly increased and the withdrawal rate decreased to 4.8%. Finally, longer-term follow up indicates that the utilization rate and the withdrawal rate have continued to improve. Conclusions: The program implemented in the present study successfully enrolled more participants in the exercise protocol, as evidenced by the increased utilization of stationary bikes and by the lower withdrawal rate. Meanwhile, the risk factors for metabolic syndrome among the participants improved dramatically, which in turn achieved the goal of primary prevention and demonstrated program effectiveness.
