Perception of health-related quality of life and psychological status in oldest hospitalized patients without cognitive impairment

The most diffuse questionnaires on health-related quality of life (HRQL) and/or psychological status (PS) consider all subjects older than 74 years, for normative reference values, in a single group without any further separation for age decades. Their authors assume that there are no further age-related differences, since older patients had a severely limited autonomy and lose the capacity of grading the severity of the diseases they are affected. Healthy subjects older than 80, without mental impairment (WMI) present an acceptable HRQL, PS and a perception of health status. No data are available on the oldest patients, carrying chronic diseases, admitted to hospital departments for acute health problems. We collected 46 WMI oldest patients (≥ 80 years), admitted for such troubles. They were investigated by the mini mental state examination (MMSE) and, in random order, the Nottingham health profile (NHP) and the psychological general well-being instrument (PGWBI). Clinical data recordings were carried out by the medical personnel, using standardized forms. The value of any individual domain of each patient was compared to the age - (≥ 75-year) and sex-matched control group derived from two large Italian population studies, using the Z-score. Charlson's comorbidity index, the index of coexistent disease (ICED), and the cumulative illness rating scale (CIRS) were also calculated. Patients older than 80 did show difference in NHP domains in comparison with normative values only for social isolation, but presented significantly worse Z-scores in all domains of PGWBI. A relationship was observed between number of daily medications and Z-scores of physical mobility and energy (NHP). Similarly, vitality (PGWBI) correlated with all comorbidity indices, ICED with positive well-being (PGWBI), pain (NHP) with CIRS subscales. Hospitalized WMI oldest subjects maintain a HRQL quite comparable to normative group of subjects older than 74 years. Furthermore, they showed a preserved correct perception of factors/diseases that possibly affect their psychological status and autonomy.
