Predictors of quality of life in hospitalized cardiac patients

Functioning and quality of life in Dutch oldest old with diverse levels of dependency

BACKGROUND

Frequently, a questionnaire like the EQ-5D is applied to investigate elderly health-related quality of life (HRQoL), but current literature suggests that inputs that go beyond these traditional health aspects might be of importance. The capability approach is a different method, which integrates several non-health-related factors to define the well-being of the oldest old.

OBJECTIVE

We propose to investigate the differences in oldest old functionings and quality of life (QoL), given different levels of dependency, using both a utility-based (EQ-5D+C) and capability-based (Currently Achieved Functioning) questionnaire.

METHODS

We interviewed 99 Dutch elderly, living in the Groningen, Veendam, and Hoogeveen areas. The average age of the elderly was 80 years, who were living independently, still looking after themselves; living semi-dependently with moderate care; or living in a nursing home requiring consistent care.

RESULTS

The utility score for the dependent group is the lowest of all three groups, across the diseases investigated in this study. The respective average utility scores calculated for the dependent, semi-dependent, and independent subgroups were 0.56 (SD ±0.10); 0.84 (SD ±0.11), and 0.69 (SD ±0.13). Mobility and pain were reported to be the major domains where problems appeared across the three groups. Additionally, dependent elderly experience deficits in the role and control functionings while the other two subgroups experience deficits in pleasure and security.

CONCLUSION

The results suggest that it is important to take note of the achievability of functionings and HRQoL, in addition to care dependency, to obtain QoL and well-being outcomes of the oldest old.

Sense of coherence as an independent predictor of health-related quality of life among coronary heart disease patients

PURPOSE

The aim of this study was to determine whether sense of coherence (SOC) at baseline predicts health-related quality of life (HRQoL) at 12-28-month follow-up among patients with coronary heart disease when controlled for sociodemographic and medical variables.

METHODS

A total of 179 consecutive patients (58.28 ± 6.52 years, 16.8% women) scheduled for coronary angiography (CAG) were interviewed before CAG and 12-28 months after. SOC was measured with the 13-item Orientation to Life Questionnaire. HRQoL was measured using the Short Form Health Survey 36 (SF-36), from which the mental and physical component summaries (MCS, PCS) were calculated. The relationship between SOC and HRQoL was examined using regression analyses.

RESULTS

SOC proved to be a significant predictor of the MCS-score (B = 0.29; 95% CI = 0.17-0.41) and PCS-score (B = 0.18; 95% CI = 0.06-0.31) when not adjusted for possible confounding sociodemographic and medical variables. After adjustment for sociodemographic and medical variables, SOC remained a predictor of the MCS-score (B = 0.26; 95% CI = 0.14-0.39). SOC also remained a predictor of the PCS-score when controlled for gender, age and family income; however, the association disappeared after adjustment for functional status (B = 0.07; 95% CI = -0.05 to 0.19).

CONCLUSIONS

SOC is a predictor of mental and physical HRQoL at 12-28-month follow-up, crude and also after adjustment. Patients undergoing CAG with low SOC thus deserve particular attention in regard to the maintenance and improvement of their HRQoL.

Re Predictors of Quality of Life in Hospitalized Cardiac Patients

A recent and interesting publication by Bruscia, Shultis, Dennery and Dileo (2008a) indicated that Sense of Coherence might be a significant predictor of Quality of Life in cardiac patients. In this short critique paper, some possible shortcomings of this study will be discussed.
