コンジョイント分析法を用いた診療放射線技師の就労環境の選好に関わる要因分析

摘要

The purpose of this study is to assess working environment preferences of radiological technologists using conjoint analysis. We carried a questionnaire survey on working environment preferences for 200 radiological technologists working in medical facilities in Japan. We defined eight characteristics for virtual medical facilities as follows: presence of colleagues who can be consulted, employment status, number of overtime work per month, academic meeting participation, number of hospital beds, presence of nuclear medicine imaging systems and radiation therapy systems, location of medical facilities, and change rate in annual income. A total of 18 virtual medical facilities were selected by an orthogonal array table using above-mentioned characteristics. The acquired data by the pairwise comparison method were analyzed by conjoint analysis. Marginal rates of substitution between income and non-pecuniary characteristics, which represent radiological technologists' preferences, were also calculated. The factors influenced on their preferences were the following: employment status is not part-time, medical facility is smaller in scale, nuclear medicine imaging systems and radiation therapy systems are set up, and the number of overtime work is less. It was suggested that radiological technologists have a tendency to avoid increase of workloads and select his/her working place with emphasis on own experiences.%近年，医療を取り巻く環境が少子高齢化の進展や医 療技術の高度化等により大きく変化している中で，医 療サービスの質の向上や，提供量の増加を願う国民の 声は強くなっている厚生労働省は，医療の質の向 上には医療従事者の働きやすい環境整備や働きがいの 向上などの雇用の質が重要であると述べている.具体的には，医療機関が勤務環境の改善に取り組むこと で，医療従事者を惹きつけられるだけでなく，医療の 質が向上し，患者の満足度も向上するといった，医療従事者•患者•医療機関の3者にとってwin-win-win となるような好循環の実現を期待している.
