Three teams improving thrombolytic therapy

BACKGROUND

The American Heart Association (AHA) standard for delivering thrombolytic therapy to chest pain patients is 30 to 60 minutes after patient presentation to the emergency department. Three acute care hospitals in an integrated health system in northern California shortened the time of administration of thrombolytic agents to appropriate patients presenting with chest pain in the emergency department.

FINDING THE SOLUTIONS

Physician-led multidisciplinary teams developed algorithms to reduce variation and decrease the thrombolytic administration process to 30 minutes. Changes were made to prehospital and hospital thrombolytic policies and staff practices.

REALIZING RESULTS

Each of the three acute care hospitals reduced their thrombolytic administration time by 48% to 59% to levels within the AHA standard.

LEARNING FROM THE PROCESS

Internal benchmarking for clinical processes promotes a synergy between hospitals and medical staffs for the improvement of patient care. Multidisciplinary teams, which include community representatives, achieve a thorough understanding of a process, which in turn reduces variation in practice and improves quality.

Growth hormone secretion in Prader-Willi syndrome

Integrated 12-hour growth hormone secretion studies, peak growth hormone response to clonidine provocation. Somatomedin-C levels, T-4 and TSH levels were studied in six growth-retarded children with the Prader-Willi syndrome, of whom five had a 15 q-karyotype. Only one of the subjects was obese. All showed abnormally low growth hormone secretion. None achieved a nocturnal peak above 10 micrograms/l, none had a mean nocturnal level over 1.8, and none showed a level above 8 micrograms/l after clonidine provocation. These findings contrasted with normal TSH in all and normal T-4 in five. These findings suggest that the poor linear growth in the Prader-Willi syndrome is caused by a true deficiency of growth hormone secretion, and that the low growth hormone levels observed in such cases are not an artifact of obesity.
