Background
Heart Failure affects over 5.7 million Americans. Heart Failure is among leading indication for
hospitalization and the discharge diagnosis for patients over 65.
39.2 billion dollars spent on heart failure related care in 2010.
Patients diagnosed with heart failure report poor quality of life, including physical, emotional and economic burden.
Research shows that early intervention after heart failure diagnosis improves survival rates, reduces readmissions, improves patient compliance with medication and diet, all leading to an improved quality of life.
UNC Charlotte School of Nursing
Purpose
Purpose of the study was to examine the change over time of quality of life (QOL) in heart failure patients utilizing population based managed care (PBMC) in an urban nurse-managed heart failure clinic in NC.
UNC Charlotte School of Nursing
AIMS
To examine quality of life in HF patients at: baseline6 months12 months
To correlate physiological and demographics with quality of life in HF patients.

Methods
This was a descriptive correlational repeated measure design study.
Subjects completed the Quality of Life Survey (SF-12).It was part of the regular patient work up at
each visit.Each subject completed 3 surveys:
baseline, 6 months and 12 months.Demographic data was collected.
UNC Charlotte School of Nursing
Instrument
SF-12 – a short form health survey with 12 questions was used to assess quality of life.
Survey includes questions related to:Physical functioningRole functioning physicalBodily painGeneral health VitalitySocial functioningRole functioning emotional Mental health
UNC Charlotte School of Nursing
Instrument
SF-12 can be reported as a total score, Physical component score (PCS) and Mental component score (MCS)
Validity and reliability of the SF-12 are well establishedReliability scores range from 0.91 to 0.92Validity scores for the PCS range from 0.43 to 0.93
(median=0.67)Validity scores for the MCS range from 0.60-1.07
(median=0.97)SF-12 has been found to be a satisfactory tool for
monitoring overall physical and mental health outcomes.
UNC Charlotte School of Nursing
Understanding Results of SF-12
Results expressed in 2 meta-scores:Physical Component Summary (PCS)Mental Component Summary (MCS)
High scores indicate better function and quality of life.
PCS and MCS scores range from 0-100Mean score 50; representing average
health status of the general population.

Effects of Age on Physical and Mental scores at each time period
Controlled for the covariates of NYHA stage and time.
Significant difference in PCS and MCS scores between subjects aged 28-69 and those older than 70.
With small sample size, further studies are needed to examine other confounding variables which could help explain differences in PCS and MCS with age.
UNC Charlotte School of Nursing
Summary of Results
There were positive changes in MCS scores over 12 month period.
There was a significant difference between QOL and HF stage.
There was a significance difference in MCS and PCS score between subjects aged 30-69 and those >70.
The PCS and MCS average scores were higher for black subjects overall.
There was no difference in results between men and women. No statistically significant difference in total QOL scores
between baseline, 6 and 12 months. PCS remained unchanged over time.
UNC Charlotte School of Nursing
Discussion
Data suggest that nurse-manage PBMC heart failure clinics helped to maintain quality of life in HF over a 12 month period.
Participants had PCS scores well below those of the general US health population.
MSC scores were at the average score for the US population.
MSC scores essentially were maintained over 12 months of participation in the HF disease management program.
UNC Charlotte School of Nursing
Limitations
Small sample sizeGeneralization of the study is limitedWhile changes across time were minimal,
a larger sample size could possibility yield significant differences
UNC Charlotte School of Nursing
Nursing Implications
This study results provide evidence to support the use of nurse-managed disease management programs for HF patients to improve both health related outcomes and quality of life.
Similar programs have been found to reduce hospital admissions, emergency room visits, hospital days and improve quality of life.
