Objective: This study surveyed staff of hospitals participating in the Taiwan Healthcare Indicator Series (THIS) Project regarding their experiences and opinions of the project. Methods: A structured questionnaire was developed via a focus group technique. The questionnaire was then forwarded to employees or directors dealing with THIS of all 234 hospitals participating in the project via electronic mail. Questions included current implementation status, problems encountered, and applications and impacts of the THIS project. Results: 120 effective responses were obtained (representing a response rate of 51.3%). The average number of reported indicators per hospital was 67. THIS included a total of 139 indicators. The most frequently used indicator selection criteria were the ease of data collection and the potential performance improvement. The most popular method of collecting data was semi-automatic. The most commonly encountered problems concerning collecting and analyzing indicators were insufficient manpower for gathering indicators and inadequate indicator analysis ability. In terms of applications of the THIS statistics, many respondents answered that they planned to submit the statistics to their chief executive officers and then integrate in the preparations for hospital accreditation. Most respondents considered participating in THIS to be helpful in identifying quality issues and improving quality of care. Conclusions: This study suggests that participating hospitals should consider collecting data through e-operation to increase reporting rate and reduce employee workload. Furthermore, the Taiwan College of Healthcare Executives can periodically hold statistical analysis workshops dealing with the THIS applications to help participants to improve their ability to analyze data and further improve hospital performance.
