title: [Emergency endoprosthesis of the hip joint. Risk of hospital mortality].
abstract: An analysis of case histories of 854 patients operated upon for fractures of the proximal part of the femoral bone at the R.R. Vreden Research Institute of Traumatology and Orthopedics for the period from September 1997 to December 2000 was made in order to assess the intrahospital lethality. The maximum season fluctuations were found to take place in October and March, minimum in September, December and April. The trend was characterized by a gradual rise from September to June. The authors associate these fluctuations with the action of external rhythmically changing factors, the growing trend--with the role of the factor of tiredness of the medical personnel. It was also shown that duration of the time interval from operation to the moment of death as well as the diversity of the value of this index was maximum in December-January and December correspondingly.
