[Show abstract][Hide abstract] ABSTRACT: The Great East Japan Earthquake occurred at 14:46 on March 11, 2011, producing serious and widespread damage. To assess damages in hospital operating departments during and after the earthquake, we surveyed hospitals in this region.
Questionnaires were sent to 415 acute care hospitals in Tohoku and east Kanto areas. The questionnaires elicited the number of perioperative patients when the earthquake hit, obstacles to continuing surgery, structural and nonstructural damage to the operating department, and the effect on routine surgery after the earthquake.
Of the 213 hospitals (51%) that completed questionnaires, 474 patients were undergoing operations during the earthquake, and 222 operations were canceled afterward. Risk factors for continuing operations, as reported by 102 hospitals, were tremors and electrical blackouts (odds ratio [OR]: 79.3 and 110.5; P < .01). In 154 hospitals, difficulties in performing operations after the earthquake were reported. Significant obstacles to the management of operations after the earthquake were characterized by infrastructure disorder scores, seismic intensity, disruption of electrical power and air conditioning, and damage to out-of-hospital telecommunications (OR, 0.46; P = .04).
Tremors and electrical blackouts were important risk factors for performing operations. Nonstructural damage, especially to out-of-hospital telecommunications, affected the management of the operating rooms. Hospital logistics are very important to achieve appropriate disaster management. (Disaster Med Public Health Preparedness. 2014;0:1-7).

[Show abstract][Hide abstract] ABSTRACT: Objective of this study is to clarify damages in operating rooms after the 2011 Tohoku Earthquake.
To survey structural and non-structural damage in operating theaters, we sent questionnaires to 155 acute care hospitals in Tohoku area.
Questionnaires were sent back from 105 hospitals (70.3%). Total of 280 patients were undergoing any kinds of operations during the earthquake and severe seismic tremor greater than JMA Seismic Intensity 6 hit 49 hospitals. Operating room staffs experienced life-threatening tremor in 41 hospitals. Blackout occurred but emergency electronic supply unit worked immediately in 81 out of 90 hospitals. However, emergency power plant did not work in 9 hospitals. During earthquake some materials fell from shelves in 44 hospitals and medical instruments fell down in 14 hospitals. In 5 hospitals, they experienced collapse of operating room wall or ceiling causing inability to maintain sterile operative field. Damage in electric power and water supply plus damage in logistics made many operating rooms difficult to perform routine surgery for several days.
The 2011 Tohoku earthquake affected medical supply in wide area of Tohoku district and induced dysfunction of operating room. Supply-chain management of medical goods should be reconsidered to prepare severe natural disaster.
