수술의 정밀화와 광범위화로 인한 수술대상의 확대와 장시간 수술의 증가, 대규모 의료기관에 대한 선호로 3차 의료기관은 수술환자가 적체되고 정규수술시간 이후의 수술실 사용시간이 증가하여 수술실 이용을 극대화하여 효율성을 크게 하는 것이 중요시되고 있다.

이 연구에서는 서울에 소재한 대학부속병원 수술실에서 2001년 10월 8일부터 11월 1일까지 시행된 수술 1,302건을 대상으로 수술실 이용지연에 영향을 주는 요인과 지연사유를 분석하고 개선이 가능한 원인을 개선하였을 때 수술실 이용률을 어느 정도 높일 수 있는가를 산정하였다. 수술 1,302건 중 지연이 있었던 수술은 372건(19.6건/일)으로 총 지연시간은 9,065분(477분/일)이었다. 연령, 성, 입원여부, 수술과, 수술시간, 마취종류, 정규수술여부, 자가통증조절장치 시술여부, 실시간대, 요일 등 10가지 변수가 지연에 영향을 미치는가를 파악하기 위해 로지스틱 회귀분석을 실시한 결과 여자가 남자보다 1.4배 높았고 수술과 A에 비해 수술과 B가 1.8배, 수술과 G가 1.7배 높았고 수술과 H가 0.4배로 적었다. 전신마취에 비해 부위마취가 2.4배 높았고 자가통증조절장치를 시술한 환자가

시술하지 않은 환자보다 0.6배로 적었다. 월요일에 비해 목요일이 1.7배 높았고 07:00-07:59 시간대에 비해 08:00-8:29 시간대가 4.3배 높았다. 지연사유로는 집도의 관련, 수술과 관련, 환자 관련, 마취과 관련, 운영시스템 관련, 병동 및 지원부서 사정이었고 개선가능한 사유로 276건(14.5건/일), 5,755분(303분/일)이 지연되었는데 주된 사유는 집도의로 인한 지연이 76건(4.0건/일)으로 1,695분(89분/일), 사용우선과 종료 후 방배정 지연이 40건(2.1건/일)으로 1,515분(80분/일), 환자이송 지연이 92건(4.8건/일)으로 1,000분(53분/일)지연되었다. 개선가능한 지연을 개선하고 마취전처치실 운영과 응급수술실 이용을 높이면 전반적 이용도를 4.09% 증가시키고 1일 744분의 새로운 사용시간을 얻을 수 있어 오후 4시 이후의 수술실 사용시간을 35% 감소시킬 수 있고 수술실 부족으로 인한 수술취소의 일부를 해결할 수 있다. 지연개선을 통한 수술실 이용 증대를 위해서는 사용시간에 근거한 우선순위과 배정, 수술스케줄의 정확한 정보제공 등 운영방법 개선과 수술에 참여하는 인력의 시간단축을 위한 자발적인 협조, 병원관리자의 지연개선에 대한 의지로 개선가능한 지연을 최대로 줄여야 한다.

Advanced surgical technology demands more precise, meticulous, and time-consuming procedures. In addition, the patient''s preference of tertiary health providers makes over crowding of the University Hospitals. Therefore, it has been necessary to maximize utilization of the operating room of such hospitals to accommodate these requirements. This study, targeting 1,302 surgical cases performed in 22 operating rooms at a university hospital in the Seoul area from October 8 to November 1, 2001, analyzed reasons for delay, and factors that caused delayed use

of operating rooms. This study also assessed that the rate of operating room use would increase if the sources for possible reform were improved. 1. Among total of 1,302 cases of surgery, the incidence of surgeries in which there were no time delays and no factors for delay were discovered is 71.4% or 930 cases: the

incidence in which surgeries were delayed was 28.6% or 372 cases. 2. In collecting data for this study, 10 variables were included: age, sex, status of the hospitalization, surgery department, operating time, type of anesthesia, elective surgery or not, use of patient controlled analgesia(PCA), time of the day, and day

of the week. Logistic regression analysis was performed to identify those factors that caused delays. Procedures involving women were delayed 1.4 times more frequently than those of men. Compared to A department, B department was 1.8 times more likely to be delayed, and H department was 0.4 times less likely to be

delayed. Regional anesthesia was 2.4 times more likely to be delayed than general anesthesia, and surgeries that PCA was applied were 0.6 times less likely to be delayed than those when it was not. Surgeries performed on the Thursday were 1.7 times more likely to be delayed than those performed on the Monday. Compared to surgeries performed between 07:00-07:59, those performed between 08:00-08:29 were 4.3 times higher. 3. The reasons for delay were related to surgeon, surgical department, patient, anesthesia, administrative system, sick ward, and support services. Among these, 5,755 minutes for 276 delayed cases could be resolved easily, and resolving delays of 3,320 minutes for 131 cases would be more difficult. Among the causes for delay that could be improved, delays due to patient''s transfer and surgeon''s factor were the most common, 21.6% and 17.4% respectively. 4. If resolvable delays are improved, pre-anesthesia room is administered, and regional anesthesia and PCA are done ahead of time, use of emergency operating rooms will increase, we can increase overall utilization by 4.09%, we will save 744 minutes a day, we can reduce the time the operation room is used after 4 PM by 35%, and we can resolve the operation cancellations due to insufficient operating rooms. For the increase in the use of operating rooms, we need to maximally decrease the delays that could be improved, by allocating block

time based on used totals hours of elective cases, giving accurate information on surgery schedule, voluntary cooperation by staff participating in surgeries in reducing delay time, and the hospital management''s will to improve delay.
