Below are two Orthodox prayers for physicians and healthcare workers. May the Lord strengthen them to always to His will!
Orthodox Prayer For Doctors and NursesO Lord Jesus Christ our God, Lover of Mankind, Physician of our souls and bodies, who didst bear the pain of our infirmities, and by whose wounds we are healed; Who gave sight to the man born blind; Who straightened the woman who was bent over for 18 years; Who gave speech and sight to the mute demoniac; Who not only forgave the paralytic his sins, but healed him to walk; Who restored the withered hand of a troubled man; Who stopped the flow of blood of her who bled for 12 years; Who raised Jairus’ daughter to life; And brought the four-day-dead Lazarus to life; And who heals every infirmity under the sun: Do now, O Lord, grant Thy grace to all those here gathered who have labored and studied hour upon hour, to go into all the world, and also to heal by the talent Thou hast given to each of them. Strengthen them, by Thy strength, to fear no evil or disease. Enlighten them to do no evil by the works of their hands, and preserve them and those they serve in peace, for Thou art our God, and we know no other, and to Thee we ascribe glory together with Thy Father who is from everlasting, and Thy most Holy, good, and life-creating Spirit, now and ever and unto ages of ages. Amen.
Another Orthodox Prayer for Physicians and Healthcare Workers
O Master, Lord our God, the Hope of all the ends of the earth, the Physician of our souls and bodies, hearken unto our entreaties on this auspicious day and hour, and to the pious love and godly fear of Your servants, as a witness to the truth of our faith, for help to all those who entreat Your mercy, and for therapy and complete healing of those who are suffering. Be the fellow worker of the physicians and surgeons, of the nurses and of all those who serve and work in service to the sick, and direct their minds and their hands towards the healing and consolation of our ailing and suffering brethren. Enlighten the physicians with perfect diagnosis, grant successful surgery and the nursing treatment of their diseases and illnesses, that, having been fully healed, Your suffering servants might in health, glorify You, together with their families and relatives, glorifying Your all-honored and magnificent Name, of the Father and the Son and the Holy Spirit, through the intercessions of our all-spotless Lady Theotokos and Ever-virgin Mary, our Father among the Saints Luke, Archbishop of Simferopol, the Physician, of the Holy wonderworking Unmercenaries Kosmas and Damian, Panteleimon the Great-martyr, and all of Your Saints. Amen.

Please also note that there is a lovely new publication of the brief life of St. Luke, his akathist, and the prayer to him for the sick, by St. Paisios Monastery.
