Abstract

Background: Dental hygienists provide direct dental care in the closest proximity to the patient, and each practice requires a high level of focus and concentration. These skills are an important human resource that can impact the quality of dental care services. Since more than half of dental clinics provide as overtime work in addition to regular hours, this study aims to determine the association between working overtime and job performance for dental hygienists. Methods: The study was conducted using a combination of online and in-person surveys via Google Forms among 131 employed dental hygienists. The survey consisted of 7 questions on demographic and work characteristics, 16 questions on characteristics related to overtime and the effect of overtime on job security, health, and life, and 10 questions on job performance, for a total of 33 questions. Chi-square analysis and independent samples t-test were used to identify the characteristics of demographic and work characteristics, and descriptive statistics analysis was used for the characteristics of overtime. Independent samples t-test was used to test the difference in the mean of job performance according to whether or not they worked overtime, and linear regression analysis was used to show the association of working overtime and job performance. Results: The study found that 71% of dental clinics worked overtime. The average number of overtime per week was once (78.5%), and the most common problems with overtime were fatigue (52.7%) and lack of personal and leisure time (41.9%). The appropriate number of overtime per week considered by dental hygienists was once a week, which was confirmed to be 94.6%. When comparing job performance by overtime status, those who worked overtime were 3.38 points higher than those who did not (35.45 vs. 32.07). Multiple linear regression analysis of the association of working overtime night and job performance showed that a one-unit increase in worked overtime was associated with a statistically significant increase in job performance of about 3.1 (p<0.01). Conclusion: Working overtime was found to have a positive effect on job performance among dental hygienists. Therefore, as a way to improve the working environment, providing appropriate compensation or welfare for overtime can reduce the negative aspects of overtime and turn it into a positive influence on job performance. This could ultimately raise awareness of the dental hygienist as a professional and effect the efficiency of dental care services.

연구배경: 치과위생사는 환자에게 가장 밀접한 위치에서 직접적인 치과 의료서비스를 제공하는 전문인력으로 진료행위마다 고도의 집중과 몰입이 요구된다. 이러한 능력은 치과의료서비스의 질적 수준 향상에 영향을 미칠 수 있는 중요한 인적자원이다. 치과의료기관의 절반이상이 정규시간 이외에 연장근무로써 야간진료를 실시하고 있어 본 연구에서는 치과위생사의 야간진료가 직무성과에 미치는 영향을 확인하고자 한다. 연구방법: 현직 치과위생사 131명을 대상으로 구글 폼을 통한 온라인 설문조사 및 직접 설문조사를 병행하여 진행하였다. 인구사회학적 및 근무특성 7문항, 야간진료와 관련된 특성 및 야간진료가 직업의 안정성 및 건강과 생활에 미치는 영향 16문항, 직무성과 10문항을 구성하여 총 33문항을 사용하였다. 인구사회학적 및 근무특성을 확인하기 위해 카이제곱 분석과 독립표본 t-test를 실시하였으며, 야간진료특성의 경우 기술통계분석을 실시하였다. 야간진료 여부에 따른 직무성과의 평균의 차이는 독립표본 t-test를 실시하였으며, 야간진료가 직무성과에 미치는 영향력은 선형회귀분석 결과로 제시하였다. 연구결과: 본 연구결과 야간진료를 하는 경우는 71%로 나타났다. 주당 평균 야간진료 횟수는 1회가 78.5%, 야간진료로 인한 문제점은 피로도(52.7%)와 개인시간 및 여가시간 부족(41.9%)이 대다수를 차지했다. 주당 적절한 야간진료 횟수는 주 1회가 94.6%로 확인되었다. 야간진료 여부에 따른 직무성과를 비교한 결과 야간진료를 하는 경우가 야간진료를 하지 않는 경우에 비해 3.38점 더 높게 나타났다(35.45점 VS 32.07점). 야간진료가 직무성과에 미치는 영향을 확인한 다중선형회귀분석 결과, 야간진료가 1단위 증가 시 직무성과는 약 3.1만큼 증가하는 것이 통계적으로 유의하게 확인되었다(p<0.01). 결론: 치과위생사의 야간진료는 직무성과에 긍정적인 영향을 미치는 요인으로 확인되었다. 따라서 근무환경의 개선책으로 야간진료에 대한 적절한 보상이나 복지의 제공을 통해 야간진료에 대한 부정적인 부분을 감소시킨다면 직무성과는 긍정적인 영향력으로 바뀔 수 있겠다. 이는 궁긍적으로 치과위생사의 전문직업인에 대한 인식제고와 더불어 치과의료기관의 효율성에도 영향을 줄 것이다.
