Overall Complication Rate

There are a number of ways hospital complications can be reported. To provide a "big picture" overall view of our performance in terms of complication rates, we have chosen to display a measure known as the Patient Safety for Selected Procedures Composite Score, otherwise known as PSI-90.

Patient Safety Indicators (PSIs) reflect quality of care inside hospitals, but focus on potentially avoidable complications and adverse events following surgeries, procedures and childbirth.

The composite score pictured below combines information for eight common patient safety problems in the hospital...Click here to expand/collapse this information +/-

  • Pressure ulcers (bed sores) - Pressure ulcers are injuries to skin and underlying tissue resulting from prolonged pressure on the skin.
  • Iatrogenic pneumothorax - This is a condition in which air or gas is present in the pleural cavity as a result of mechanical ventilation, tracheostomy tube placement, or other therapeutic intervention.
  • Infection due to medical care - (see central venous catheter-related blood stream infection rate*)
  • Postoperative hip fracture - This is the rate of patients who fractured their hip during their admission after a surgery, but were not a paitient who was at a high risk for falling (e.g., seizures, syncope, stroke, occlusion of arteries, psychoses, musculoskeletal disorders, etc.), suffered a self-inflicted injury, or was an obstetric case.
  • Postoperative pulmonary embolism or deep vein thrombosis - Pulmonary embolism is a blockage in one of the pulmonary arteries in your lungs. In most cases, pulmonary embolism is caused by blood clots that travel to the lungs from the legs or, rarely, other parts of the body (deep vein thrombosis). Because pulmonary embolism almost always occurs in conjunction with deep vein thrombosis, most doctors refer to the two conditions together as venous thromboembolism. Although anyone can develop deep vein thrombosis (DVT) and pulmonary embolism, factors such as immobility, cancer and surgery increase your risk (mayoclinic.org).
  • Postoperative sepsis - One area where many patients are the victims of doctor or hospital staff error is in the area of post operative infection or sepsis. Sepsis is a potentially deadly condition where an infection overwhelms a patient’s immune system. It can occur when the surgical site is not properly sterilized, pre-operative antibiotics are not administered properly, or sugical instruments are not properly sterilized.
  • Postoperative wound dehiscence - Wound dehiscence is the parting of the layers of a surgical wound. Either the surface layers separate or the whole wound splits open. Wound dehiscence varies depending on the kind of surgery you have.
  • Accidental puncture or laceration - This can be an accidental cut, puncture, perforation, or laceration during a procedure; this does not include an injury, tear or repair that was reasonably necessary to accomplish a surgery. 

The composite score is an average of the above problems. A score less than 1 indicates that the hospital had fewer selected patient safety events than other hospitals with a similar case mix. A score greater than 1 indicates the hospital had more selected patient safety events than other hospitals with a similar case mix.


UTMB’s Overall Complication Rate (PSI-90 rate) has decreased (improved) over the last 4 years. UTMB’s overall complications rate has consistently remained below (better than) that of our Academic Medical Center Peers since 2012.
