Analysis of cost and assessment of computerized patient record systems in Japan based on questionnaire survey.
OBJECTIVE
The purpose of this study was to clarify the implementation and maintenance costs of a computerized patient record (CPR) system by means of a questionnaire survey. Moreover, the benefits of CPR systems were evaluated to determine their contribution to enhancing the quality of medical care and hospital management.


METHODS
Data were collected by a questionnaire survey mailed out to participants.


RESULTS
The per-bed mean cost for implementation was 14,308 dollars (range: 3538-38,077 dollars). The mean annual maintenance cost for the CPR system was 457,615 dollars (range: 39,769-2,307,692 dollars). The multivariate analysis (Hayashi's Quantification Type I) revealed high partial correlation coefficients between implementation cost and the CPR system maker. In addition, the multiple correlation coefficient for four factors (CPR system maker, number of servers, institution type and implementation date) in predicting implementation cost was 0.798. Over 60% of respondents replied that their satisfaction with the CPR system was 'very high' or 'high.' Eighty-two percent of the hospitals responded positively that CPR systems improve the quality of medical care, and 70% felt that the systems help prevent medical errors.


CONCLUSIONS
Our findings indicate that the maker of CPR system, number of servers, institution type and implementation date had a strong influence on per-bed implementation costs in that order. Finally, it was found that CPR systems were considered effective for hospital administration and medical examinations, based on the high assessments of the results of installing a CPR system.
