This study describes the continuation of a program to improve hospital outcomes in the hospitals of Syracuse, New York using the Potentially Preventable Complications (PPC) System developed by 3M™ Health Information Systems. This area includes a resident population of 446,065 and four hospitals, three of which participated in the study. The program is noteworthy because it involves a group of competing hospitals in the same community working together to reduce adverse patient outcomes and related costs [
10].
The initial component of this program involved identification of the increased costs generated by inpatient complications. A major driver of the program in the Syracuse hospitals was the potential for reducing the costs of PPCs. Analyses of patients assigned to the same All Patients Refined Diagnosis Related Groups and severity of illness categories demonstrated that those who experienced PPCs had actual costs three to four times higher than those who did not [

The implementation of programs to address inpatient complications in the Syracuse hospitals occurred between October 2008 and June 2009. At each hospital, the program included the following components based on PPCs [

Identification and Implementation of Interventions
Since June 2009, the community wide program to address inpatient complications has evolved and matured. This study describes that process at each of the participating hospitals and suggests relevant conclusions.
Community General Hospital
Between October 2008 and September 2010, efforts to reduce PPCs at Community General Hospital focused on clostridium difficile colitis, urinary tract infections, post hemorrhage and acute anemia, pulmonary embolism, and venous thrombosis. These efforts were managed by the Chief Fiscal Officer and the Infection Control Manager with support from the Department of Quality Assurance. Throughout the demonstration project, monthly data were provided by the Hospital Executive Council.
Reduction of infections for clostridium difficile colitis has been a focus at the Hospital. Much of this activity has involved environmental efforts to control this organism. Education of the environmental services department staff through the Office of Infection Control has been a key to preventing its spread. In 2009, terminal cleaning times for patient rooms, toilet rooms, showers, medication rooms, kitchens, and utility spaces were updated. In addition, policies and procedures for identification and management of this infection were revised and updated. The Office of Infection Control and the Hospital Epidemiologist have monitored antibiotic use and assign patients with diarrhea to private rooms.
Urinary tract infection has been the PPC with the highest rate per 1,000 discharges at the hospital, although its incidence has declined. In order to address this complication, procedures for management of patients with foley catheters were implemented through the Office of Infection Control in September 2008. Since that time, the Office has aggressively managed implementation of these procedures and reviewed PPCs that were identified for this infection.
Complications related to post hemorrhagic and acute anemia with transfusions were found to be related to a medical staff practice pattern for orthopedic patients discharged to nursing homes during 2009. Since that time, the practice pattern has been revised through cooperation among the Chief Fiscal Officer, the Chief of Orthopedics, and the physicians involved. This occurred through review of transfusion policies and communication of guidelines to surgeons and physician assistants.
Venous Thrombosis and Pulmonary Embolism have been the subject of efforts at Community-General Hospital because of the severity of these complications. Review of PPC data for these diagnoses by the Chief Fiscal Officer and the Office of Infection Control have not identified any patterns by service area. Between 2008 and 2009, efforts to improve care for deep venous thrombosis resulted in a change in vendors for PICC line catheters and the use of more large diameter catheters by the hospital administration and medical staff. Subsequent review of experience resulted in a return to the original vendor and greater use of small bore catheters in 2010. In 2010, risk assessment and prophylaxis order forms for venous thrombosis and pulmonary embolism were revised and implemented throughout the hospital.
Crouse Hospital
Efforts to reduce PPCs at Crouse Hospital have focused on urinary tract infection, decubitus ulcer, pulmonary embolism, and central venous catheter infections. These efforts have been managed by specific hospital staff and physician champions through the Quality Assurance Department. The hospital used the PPC software to monitor these efforts during 2008 and 2009, discontinued this process in the initial quarters of 2010, then returned to it in July of that year. For the 2008 - 2009 and the third quarter of 2010, monthly PPC data were provided by the Hospital Executive Council.
PPCs involving urinary tract infection experienced the highest frequency at Crouse Hospital during the period of the study. Interventions that were initiated in 2008 included the placement of stickers in patient charts by the nursing staff which requested the physician to remove the sticker if the patient's condition did not warrant it, or to renew the order if it was. Beginning in 2008, educational programs were implemented by hospital infection control nurses to encourage early removal of urinary catheters. Followup education was provided by these nurses when urinary tract infections were identified. In addition, education was provided to Clinical Documentation Specialists and physicians on the nursing units to ensure that these complications were documented correctly.
PPCs involving decubitus ulcers at Crouse Hospital, although not involving large numbers of patients, have generated long inpatient stays and been addressed by the program. Beginning in 2008, the Inservice Education Department has provided extensive training to physicians and nurses in comprehensive skin assessment, staging of ulcers present on admission, and identification of patients at risk of this complication. Each patient admitted to a critical care or a medical surgical unit received an assessment within 24 hours of admission and daily reassessments. Interventions that were implemented to prevent this complication included specialty mattresses, turning and positioning procedures, nutrition involvement, skin cleansing, moisture management, and use of chair cushions.
Pulmonary Embolism as a PPC has been addressed by a series of interventions at Crouse Hospital beginning in June 2009. This program has been developed and implemented by a physician champion and a hospital pharmacist. A protocol and related form that include a risk assessment was developed for use with each medical/surgical inpatient. The form included recommendations for mechanical and pharmaceutical interventions for each patient. Copies were placed in each patient chart. Interventions included ambulation for patients identified as being at low risk and mechanical and pharmaceutical interventions for patients at moderate to high risk.
PPCs for infections due to central venous catheters have been addressed by a series of initiatives at Crouse Hospital beginning in 2010. These efforts have been managed by the hospital Physician Epidemiologist and two Nurse Administrators with interests in this area. During 2009, a central line bundle was implemented at the hospital, however, infection rates did not improve as anticipated. During 2010, a pilot program was implemented on a single nursing unit including the use of a needle less connector and a PICC line team assuming responsibility for dressing changes, assessment, and connector changes for all central lines.
St. Joseph's Hospital Health Center
Reduction of PPCs at St. Joseph's Hospital Health Center focused on pneumonia, decubitus ulcer, and post hemorrhagic and other acute anemia with transfusion. The management of this process involved from an administrative vice president, to the nurse managers of inpatient units, to the infection control manger, the respiratory therapy manager, and the product line manager for orthopedics. Beginning in October 2008, this process was supported by monthly reports including PPC data developed by the Hospital Executive Council.
Reduction of inpatient complications for pneumonia was the largest quality assurance challenge at St. Joseph's Hospital Health Center. During 2008, this diagnosis accounted for 18.2 percent of all PPCs at the Hospital.
Between October and December 2008, efforts in this area focused on ventilator associated pneumonia through the implementation of a protocol for management of ventilator patients under the leadership of the Vice Presidents for Nursing and Utilization Management. By February 2009, the incidence of this complication had been effectively eliminated.
During 2009, efforts to reduce the incidence of remaining complications involving hospital acquired pneumonia not involving ventilators were directed by Nurse Managers and other administrative staff. They focused on implementation of interventions such as early ambulation and respiratory care for patients experiencing cardiac surgery and intensive care.
Beginning in October 2009, the Chief Nursing Officer and the Manager of Infection Control became involved with this process. This resulted in organization of a program to address pneumonia as a PPC including the following specific interventions.
- Elevation of head of bed 30 - 45 degrees if not medically contraindicated
- Hourly use of incentive spirometry
- Assistance with ambulation
- Encouragement of cough, deep breathing
- Use of hand hygiene protocol
This program was initially implemented in the first quarter of 2010 through the Office of Infection Control and the Inservice Education Department. Analysis of PPC data for this period demonstrated that many patients in the target population did not receive the interventions. This resulted in a change in management to the Office of Infection Control and the Respiratory Therapy Department. Under this structure, the number of patients receiving the intervention increased substantially. This process was supported through the provision of aggregate and patient specific data for patients with the pneumonia PPC at two week intervals by the Hospital Executive Council.
Reduction of PPCs at St. Joseph's Hospital Health Center also involved decubitus ulcer. This was diagnosis with relatively small volume that added large numbers of days to inpatient stays. The program was managed by the Vice Presidents for Nursing and Utilization. Interventions included the implementation of comprehensive skin assessments for all medical/surgical inpatients on admission. In addition, specialty pressure mattresses were installed in all inpatient beds.
Initial efforts to reduce PPCs at St. Joseph's Hospital Health Center also included post hemorrhagic and other acute anemia with transfusion. This program was managed by the Vice President for Utilization and product line managers for orthopedics and other services. The cause of this complication was determined to be a practice pattern that resulted in the ordering or transfusions for patients requiring long term care immediately prior to discharge. This issue was addressed through revision of guidelines for the patients at risk and through revision of administrative procedures for authorization of transfusions.
Further efforts to manage inpatient complications at St. Joseph's Hospital Health Center will focus on additional complications and interventions. Because of the large size of the adult medical/surgical inpatient population at this hospital, they will also involve early identification of high risk patients to make best use of available resources.
Study Analysis
The study compared the frequencies and rates of PPCs for each category in which an intervention was implemented in the three Syracuse hospitals. In addition, the frequencies and rates of all PPCs were compared hospital wide. The comparisons involved January - September 2008 - 2010. The 2008 period included the nine months immediately prior to the implementation of interventions, while the 2009 and 2010 periods included their impact.
In order to evaluate the impact of changes in the composition of the hospital populations for inpatient complications, the analysis also included comparisons of hospital complication rates with those of benchmark populations with the same severity of illness. The benchmark populations were based on California and New York State inpatient data. In the analyses p = <0.05 was the accepted alpha level employed in the methodology.
