Urinary tract infection (UTI) is among the most common bacterial infections in women of all ages but the incidence increases with older age. Despite the fact that UTI is a common problem it is still poorly investigated regarding its connection with experienced health and morale. The aim of this study was to explore the impact of a diagnosed, symptomatic urinary tract infection (UTI) with or without ongoing treatment on morale or subjective wellbeing among very old women.
In a cross-sectional, population-based study, 504 women aged 85 years and older (range 84-104) were evaluated for ongoing UTI. Of these, 319 (63.3%), were able to answer the questions on the Philadelphia Geriatric Center Morale Scale (PGCMS) which was used to assess morale or subjective wellbeing.
In the present study sample of 319 women, 46 (14.4%) were diagnosed as having had a UTI with or without ongoing treatment when they were assessed. Women with UTI with or without ongoing treatment had significantly lower PGCMS scores (10.4 vs 11.9, p = 0.003) than those without UTI, indicating a significant impact on morale or subjective wellbeing among very old women. Depression (p < 0.001), UTI (p = 0.014) and constipation (p = 0.018) were the medical diagnoses significantly and independently associated with low morale in a multivariate regression model.
As UTI seems to be independently associated with low morale or poor subjective wellbeing, there needs to be more focus on prevention, diagnosis and treatment of UTI in old women.
Urinary tract infection (UTI) is among the most common bacterial infections in women of all ages but the incidence increases with older age. Almost half of all women have suffered from at least one UTI sometime during their reproductive years and this increases to at least 60% in postmenopausal women [1–3]. Important risk factors are oestrogen deficiency, urinary retention, urinary incontinence, a prior history of UTI, sexual activity and diabetes [2–5]. UTI in older patients can be a complex problem in terms of approach to diagnosis, treatment and prevention because in older patients it frequently presents with a range of atypical symptoms such as delirium, gastrointestinal signs and falls [6–11]. Caregivers may not always understand the impact that an apparently trivial illness such as UTI has on the patient and successful treatment from a medical point of view may not always translate into enhanced quality of life .
Although uncomplicated UTI in women is considered to be a relatively benign and self-limiting condition, it has an effect on the quality of life and causes unnecessary suffering, for example in the form of weakness and a feeling of being ill [13, 14]. Any illness, even if short-lived and not life-threatening, can have an important impact on the patient's daily activities, social functioning and wellbeing [15, 16]. Acute cystitis, as well as a failure of the treatment, and adverse effects of antibiotics can reduce women's quality of life .
Quality of life is a multidimensional concept and could be difficult to define faced with the lack of a consensual definition. Subjective indicators, however, such as sense of wellbeing and satisfaction with life can describe the concept. The World Health Organization Quality of Life Group (WHOQOL) (1995) defined quality of life as the "individual's perception of their position in life in the context of the culture and value systems in which they live and with regard to their goals, expectations, standards and concerns" (p. 1403). Quality of life includes at a minimum physical, psychological and social dimensions. The physical dimension describes the individual's perception of their physical state, the psychological dimension the individual's perception of their cognitive and affective states and the social dimension describes the individual's perception of the interpersonal relationships and social roles in their life . Various concepts, such as life satisfaction, subjective or psychological wellbeing and morale are used synonymously in the literature . Morale, which we chose to use in this study, is defined by Lawton as a basic sense of satisfaction with oneself, a feeling that there is a place in the environment for oneself, and a certain acceptance of what cannot be changed . Morale has been reported to be influenced by different medical conditions such as diabetes, stroke, depression, Parkinson's disease and heart failure [21–23]. Those with high morale are often active, sociable and optimistic in their attitudes but these attributes are not essential components of high morale . Morale can be influenced by depression but it is not known whether low morale is a predictor of depression [22, 23]. People can still have high morale even if their philosophy of life is pessimistic and if they are inactive and solitary . Despite the fact that UTI is a common problem it is still poorly investigated regarding its connection with experienced health and morale. There is a lack of population-based studies in very old women with ongoing UTI and its association with morale. The purpose of this study was to explore whether a diagnosed symptomatic UTI with or without ongoing treatment had any impact on morale or subjective wellbeing among very old women.
These 504 women comprised 85-year-olds (n = 172), 90-year-olds (n = 169) and ≥95-year-olds (n = 163). The Philadelphia Geriatric Center Morale Scale (PGCMS) was used to assess morale and 185 of the 504 women were unable to answer the questions or declined to receive home visits. They did not differ from the remaining sample regarding the prevalence of UTI but they were older and a larger proportion suffered from dementia. The final study sample consisted of 319 participants and comprised 85-year-olds (n = 119), 90-year-olds (n = 110) and ≥95-year-olds (n = 90).
The same procedure was used, as in the Umeå 85+ study, which has been described in detail earlier . The investigator, who was a nurse, a physician, a physiotherapist or a medical student, made one or more home visits to those who gave their consent. Each home visit, including assessments and a structured interview, took approximately two hours to complete. Data were also collected from medical records, from hospitals and from the patient's general practitioner, and from caregivers and relatives.
The GERDA project includes information about social background variables such as living conditions and both participants living in their own homes and those living in institutions were included.
Medical history and current health status as well as current drug use - both prescription and non-prescription drugs - were also included in the information. Reliable and well-known assessment scales were used. The Mini Mental State Examination (MMSE) was used to assess cognition in the participants. The scale has a maximum score of 30 with a score of 23 or less indicating impaired cognition . The Geriatric Depression Scale-15 (GDS-15) was used to assess depressive symptoms. Scores of between five and nine indicate mild depression, and a score of ten or more indicates moderate to severe depression 
Dependency in activities of daily living was assessed using the ADL Staircase (including the KATZ Index of ADL) which measures both Instrumental ADL and Personal ADL  and the Barthel ADL Index with a maximum score of 20 indicating independence in all personal ADL activities . The participants' height and weight were assessed and Body Mass Index (BMI) calculated (kg/m2).
Based on all assessments, drug treatments and all documentation in medical records a specialist in geriatric medicine evaluated all data, in order to arrive at diagnoses, using the same criteria for all participants. Dementia and depression were diagnosed according to the DSM IV criteria, based on medical history, test results and medical record notes.
Quality of life instruments for old people were reviewed by the British Geriatrics Society and the Royal College of Physicians of London. They recommend the use of the PGCMS for assessment of morale or subjective wellbeing among old people . This study assessed morale using the 17-item British English version of the PGCMS, translated into Swedish [20, 22, 30]. The scores range from 0 to 17, where scores of 17-13 indicate high morale, 12-10 middle range and 9-0 low morale. The PGCMS is also comparatively easy to use in people with mild to moderate cognitive impairment since the questions only require yes/no answers [20, 29]. In this study, the scale was interviewer administered.
Definition of UTI
UTI was diagnosed if the person had a documented symptomatic UTI, with either short or long-term ongoing treatment with antibiotics, or symptoms and laboratory tests judged to indicate a UTI by the responsible physician or the assessor. Medical records from the general practitioner, from the hospitals in the catchment area or records from the caring institutions were also investigated to evaluate and validate the UTI diagnosis. The UTI diagnosis in the medical records was based on urinary tests in combination with symptoms that were judged to be associated with UTI by the responsible physician. In addition, the results from all urinary cultures registered at the regional bacteriological laboratory were reviewed. This means that the UTI diagnose was registered if the participants had symptoms and/or signs of UTI when they were assessed or had had a recent diagnosis of UTI.
The χ2 and Student's t-tests were used to analyze differences between groups and Pearson's correlation analyses were used for associations between continuous variables. A multivariate linear regression model was constructed, based on a priori hypotheses that morale could be influenced by medical conditions such as infections, diabetes, stroke, depression, Parkinson's disease and heart failure. Diagnoses that had a statistically significant association with low PGCMS scores were included in multivariate linear regression models to find the independent diagnoses associated with PGCMS scores. A p-value of < .05 was regarded as statistically significant. The Predictive Analytics Software (PASW) Statistics version 18 (SPSS Inc., Chicago, IL) was used for the calculations.
The study was approved by the Regional Ethical Review Board in Umeå (registration number 05-063M) and the Ethics Committee of Vaasa Central Hospital (registration number 05-87).

Urinary tract infection with or without ongoing treatment
In the present study sample, 14% of very old women had a diagnosed UTI with or without ongoing treatment and the prevalence increased with age. UTI was associated with a significantly lower PGCMS score in this study and UTI, depression and constipation were the diagnoses independently associated with low morale in a multivariate regression model in old women. Diagnoses such as malignancies, rheumatic diseases, stroke, dementia, heart failure and diabetes were not significantly associated with low morale in the regression model. It was remarkable that although the women with UTI were receiving ongoing treatment at the time that they were assessed using the PGCMS, they nevertheless experienced low morale.
Old age is associated with reduced reserve capacity and in addition many old women suffer from multiple diseases. Very old women, as in this study, may have major responses to relatively minor insults such as infections and constipation. Thus, in a frail old woman a UTI might have a more serious impact on morale than in younger and healthier people. Another possible explanation might be that these women felt ill as a result of the medical treatment itself or because the treatment did not have the expected effect on the UTI. It has previously been shown that adverse effects of antibiotics as well as treatment failure can reduce quality of life . Another explanation might be that these women have an enduring feeling of poor wellbeing over a long period of time, despite medical treatment of their UTI.
The association between UTI and morale among these old women in the present study is in line with previous findings from studies among younger women [14, 16, 31]. Women with UTI experience the symptoms in various ways but descriptions of the difficulty of enduring such symptoms as burning are common . The symptoms are also described as a general feeling of being physically miserable as well as tired and irritable. The results indicate that UTI has a significant effect on morale despite the fact that the general opinion is that it is a "harmless" disease. A somewhat surprising finding in this study was that UTI with or without ongoing treatment - but not urinary incontinence - had a significant impact on morale in these old women. Especially since previous studies have found that, old women, suffering from urinary incontinence often have a reduced quality of life [32, 33]. However, in the present study UTI in old women seems to be more important for morale than urinary incontinence. It is not unusual for UTI and urinary incontinence to have similar symptoms and sometimes incontinence itself is a symptom of a UTI. Thus it is sometimes possible to deal with urinary incontinence problems by treating the UTI. Nevertheless, it is important for the caregivers to be aware of both UTI and urinary incontinence, since both might have an impact on old women's morale.
As one might expect, in the present study depression was associated with low morale according to the PGCMS in the univariate analyses and also remained so in the final multivariate linear regression model. These findings are supported by previous studies [23, 34] which have shown that depression is associated with a number of diagnoses, concomitant problems and disabilities in daily life. Depression among old women is common, it often remains undiagnosed and untreated, and influences their morale. In previous studies depression was found to be associated with institutional care, experienced loneliness and feeling unsafe [34, 35]. In addition, depressed people more often suffered from constipation, dementia, osteoporosis, impaired vision, used a large number of medications, had lower scores on the MMSE and MNA and were older . Although depression and low morale are closely connected they cannot be considered as synonymous because people with depression can have high morale and people with low morale are not always depressed . The PGCMS and GDS scales measure different aspects of the person's well- or ill-being and using both scales is therefore worthwhile. High scores on the GDS are probably a better predictor of low morale than low PGCMS scores are of depression [23, 36].
Women with constipation tend to have a poorer quality of life and low morale, which is supported by previous studies in younger old women and men [37, 38]. Constipation seems to have a substantial impact on these women's activities of daily life and they experienced poorer health. It is common for there to be a difference between the patient's and physician's perceptions of the importance of the symptoms and how they affect the patient's daily life and morale [7, 12, 39]. The discrepancy between these perceptions could be an effect of poor patient-physician communication or differences in understanding of the illness [12, 40].
Even if such conditions as UTI and constipation are in fact considered trivial illnesses and are not always regarded as important, they seem to have a significant impact on morale in old women [13, 14]. These conditions are sometimes neglected and underdiagnosed, and underlying causes are often not investigated. UTIs in old women are frequently treated with antibiotics, but as prevention and treatment of underlying risk factors for UTI are often ignored recurrent UTI is common among these women. It is important for all care givers working with old women to pay attention to such common diagnoses as UTI and constipation since they are amenable to inexpensive and non invasive intervention. It is also important that they be aware of signs of low morale and use scales such as the PGCMS to identify such signs. Since low morale might be caused by underlying diseases, such as UTI and constipation, patients with low morale must be assessed for underlying causes.
The PGCMS is described as an appropriate instrument for measuring morale or subjective wellbeing among very old people [20, 29]. The strength of this instrument lies in the scale, developed for use with older people, which is easily self- or interviewer- administered and also applicable to participants with mild and moderate cognitive impairment since the 17 questions can be answered with only yes or no [20, 29, 30]. The scoring of the PGCMS has an acceptable level of reliability, validity and a high internal consistency .
One limitation of the present study was that in the oldest age group, several women could not complete the PGCMS due to severe cognitive impairment. Another limitation was that no urinary tests or urine cultures were taken in conjunction with the home visits when the PGCMS was performed which makes it impossible to evaluate whether the participants with UTI with ongoing treatment had responded to treatment.
UTI, depression and constipation are common among very old women and are associated with low morale or poor subjective wellbeing. More attention has to be given to very old women with UTI and UTI has to be prevented, detected and treated if these women are to have a good old age. Since there is a high incidence of UTI among old women combined with an ongoing increase in the older population, there is a great need for further research, such as intervention studies or how old women experience their health and life in general during an ongoing UTI.
