Sleep in spousal Alzheimer caregivers: a longitudinal study with a focus on the effects of major patient transitions on sleep

Findings on sleep disturbances in family dementia caregivers are conflicting. We studied the longitudinal effects of dementia caregiving and major transitions in the caregiving situation on caregivers' sleep and the effect of moderating variables.

A Longitudinal Analysis of the Relations Among Stress, Depressive Symptoms, Leisure Satisfaction, and Endothelial Function in Caregivers

Stress and depressive symptoms have been associated with impaired endothelial function as measured by brachial artery flow-mediated dilation (FMD), possibly through repeated and heightened activation of the sympathetic nervous system. Behavioral correlates of depression, such as satisfaction with leisure activities (i.e., leisure satisfaction), may also be associated with endothelial function via their association with depressive symptoms. This study examined the longitudinal associations between stress, depressive symptoms, leisure satisfaction, and endothelial function as measured by FMD.

Avoidant coping partially mediates the relationship between patient problem behaviors and depressive symptoms in spousal Alzheimer caregivers

OBJECTIVE: Caring for a loved one with Alzheimer disease is a highly stressful experience that is associated with significant depressive symptoms. Previous studies indicate a positive association between problem behaviors in patients with Alzheimer disease (e.g., repeating questions, restlessness, and agitation) and depressive symptoms in their caregivers. Moreover, the extant literature indicates a robust negative relationship between escape-avoidance coping (i.e., avoiding people, wishing the situation would go away) and psychiatric well-being. The purpose of this study was to test a mediational model of the associations between patient problem behaviors, escape-avoidance coping, and depressive symptoms in Alzheimer caregivers. METHODS: Ninety-five spousal caregivers (mean age: 72 years) completed measures assessing their loved ones' frequency of problem behaviors, escape-avoidance coping, and depressive symptoms. A mediational model was tested to determine if escape-avoidant coping partially mediated the relationship between patient problem behaviors and caregiver depressive symptoms. RESULTS: Patient problem behaviors were positively associated with escape-avoidance coping (beta = 0.38, p < 0.01) and depressive symptoms (beta = 0.26, p < 0.05). Escape-avoidance coping was positively associated with depressive symptoms (beta = 0.33, p < 0.01). In a final regression analysis, the impact of problem behaviors on depressive symptoms was less after controlling for escape-avoidance coping. Sobel's test confirmed that escape-avoidance coping significantly mediated the relationship between problem behaviors and depressive symptoms (z = 2.07, p < 0.05). CONCLUSION: Escape-avoidance coping partially mediates the association between patient problem behaviors and depressive symptoms among elderly caregivers of spouses with dementia. This finding provides a specific target for psychosocial interventions for caregivers.

Personal mastery attenuates the effect of caregiving stress on psychiatric morbidity

This study examined the protective effects of personal mastery on the relations between both objective and subjective stress and psychiatric morbidity in 79 spousal Alzheimer caregivers. Results indicated that with low mastery, the relations between patient problem behaviors and caregiver psychiatric symptoms was significant (t[71] = 2.03; p = 0.046). However, with high mastery, no significant association was found (t[71] = -0.76; p = 0.452). Similarly, the relations between role overload and psychiatric morbidity was significant when mastery was low (t[71] = 2.22; p = 0.029), but not high (t[71] = -1.49; p = 0.140). These results suggest that caregivers with a greater sense of personal mastery may be protected from the negative effects of caregiver stress.

The moderating effect of personal mastery and the relations between stress and Plasminogen Activator Inhibitor-1 (PAI-1) antigen

OBJECTIVE: This study tested whether feelings of personal control over one's life circumstances (i.e., personal mastery) would attenuate the relations between stress (i.e., negative life events and caregiving distress) and Plasminogen Activator Inhibitor (PAI)-1 antigen, an inhibitor of fibrinolysis implicated in the development of cardiovascular disease. DESIGN: Seventy-one spousal dementia caregivers were assessed for plasma levels of PAI-1 antigen, negative life events, caregiver distress, and feelings of personal mastery. Regression analysis was used to determine if personal mastery moderated the relations between stress (i.e., life stress and caregiving distress) and PAI-1 antigen levels. MAIN OUTCOME MEASURE: Plasminogen activator inhibitor (PAI)-1 antigen in plasma. RESULTS: After controlling for other factors associated with PAI-1 antigen levels, negative life events were positively associated with plasma PAI-1 antigen concentrations in participants low in personal mastery (beta = .31; p = .050) but not in individuals high in personal mastery (beta = .22; p = .184). The moderating effect of mastery on the relations between caregiving distress and PAI-1 antigen did not reach statistical significance (p = .091). CONCLUSIONS: These data suggest that mastery may protect individuals from some of the alterations in hemostatic factors that have been linked to cardiovascular risk.

Effects of gender and dementia severity on Alzheimer's disease caregivers' sleep and biomarkers of coagulation and inflammation

BACKGROUND: Being a caregiver for a spouse with Alzheimer's disease is associated with increased risk for cardiovascular illness, particularly for males. This study examined the effects of caregiver gender and severity of the spouse's dementia on sleep, coagulation, and inflammation in the caregiver. METHODS: Eighty-one male and female spousal caregivers and 41 non-caregivers participated (mean age of all participants 70.2 years). Full-night polysomnography (PSG) was recorded in each participants home. Severity of the Alzheimer's disease patient's dementia was determined by the Clinical Dementia Rating (CDR) scale. The Role Overload scale was completed as an assessment of caregiving stress. Blood was drawn to assess circulating levels of D-dimer and Interleukin-6 (IL-6). RESULTS: Male caregivers who were caring for a spouse with moderate to severe dementia spent significantly more time awake after sleep onset than female caregivers caring for spouses with moderate to severe dementia (p=.011), who spent a similar amount of time awake after sleep onset to caregivers of low dementia spouses and to non-caregivers. Similarly, male caregivers caring for spouses with worse dementia had significantly higher circulating levels of D-dimer (p=.034) than females caring for spouses with worse dementia. In multiple regression analysis (adjusted R(2)=.270, p<.001), elevated D-dimer levels were predicted by a combination of the CDR rating of the patient (p=.047) as well as greater time awake after sleep onset (p=.046). DISCUSSION: The findings suggest that males caring for spouses with more severe dementia experience more disturbed sleep and have greater coagulation, the latter being associated with the disturbed sleep. These findings may provide insight into why male caregivers of spouses with Alzheimer's disease are at increased risk for illness, particularly cardiovascular disease.

Personal mastery is associated with reduced sympathetic arousal in stressed Alzheimer caregivers

OBJECTIVES: Spousal caregivers of Alzheimer's disease patients are at increased risk for cardiovascular disease, possibly via sympathetic response to stressors and subsequent catecholamine surge. Personal mastery (i.e., belief that one can manage life's obstacles) may decrease psychological and physiological response to stressors. This study examines the relationship between mastery and sympathetic arousal in elderly caregivers, as measured by norepinephrine (NE) reactivity to an acute psychological stressor. DESIGN: Cross-sectional. SETTING: Data were collected by a research nurse in each caregiver's home. PARTICIPANTS: Sixty-nine elderly spousal Alzheimer caregivers (mean age: 72.8 years) who were not taking beta-blocking medication. INTERVENTION: After assessment for mastery and objective caregiving stressors, caregivers underwent an experimental speech task designed to induce sympathetic arousal. MEASUREMENTS: Mastery was assessed using Pearlin's Personal Mastery scale and Alzheimer patient functioning was assessed using the Clinical Dementia Rating Scale, Problem Behaviors Scale, and Activities of Daily Living Scale. Plasma NE assays were conducted using pre- and postspeech blood draws. RESULTS: Multiple regression analyses revealed that mastery was significantly and negatively associated with NE reactivity (B = -9.86, t (61) = -2.03, p = 0.046) independent of factors theoretically and empirically linked to NE reactivity. CONCLUSIONS: Caregivers with higher mastery had less NE reactivity to the stressor task. Mastery may exert a protective influence that mitigates the physiological effects of acute stress, and may be an important target for psychosocial interventions in order to reduce sympathetic arousal and cardiovascular stress among dementia caregivers.

Positive Affect and Sleep in Spousal Alzheimer Caregivers: A Longitudinal Study.

This article examines the longitudinal relation between positive affect (PA) and sleep in 126 spousal Alzheimer's disease caregivers. Caregivers underwent 4 yearly assessments for the Positive and Negative Affect Schedule, the self-rated Pittsburgh Sleep Quality Index, and actigraphy to objectify nighttime total sleep time, wake after sleep onset, and percentage of sleep. Increased levels of PA and a greater positivity (i.e., positive-to-negative affect) ratio were significantly associated with better subjective sleep over the entire study period. Yearly increases in PA-even when controlling for negative affect (NA)-and in the positivity ratio were also associated with better subjective sleep. PA and actigraphy measures showed no significant relations. Increased PA is longitudinally associated with better sleep in dementia caregivers largely independent of NA.

Higher emotional distress in female partners of cancer patients: prevalence and patient-partner interdependencies in a 3-year cohort

OBJECTIVE: Assessment and treatment of psychological distress in cancer patients was recognized as a major challenge. The role of spouses, caregivers, and significant others became of salient importance not only because of their supportive functions but also in respect to their own burden. The purpose of this study was to assess the amount of distress in a mixed sample of cancer patients and their partners and to explore the dyadic interdependence. METHODS: An initial sample of 154 dyads was recruited, and distress questionnaires (Hospital Anxiety and Depression Scale, Symptom Checklist 9-Item Short Version and 12-Item Short Form Health Survey) were assessed over four time points. Linear mixed models and actor-partner interdependence models were applied. RESULTS: A significant proportion of patients and their partners (up to 40%) reported high levels of anxiety, depression, psychological distress, and low quality of life over the course of the investigation. Mixed model analyses revealed that higher risks for clinical relevant anxiety and depression in couples exist for female patients and especially for female partners. Although psychological strain decreased over time, the risk for elevated distress in female partners remained. Modeling patient-partner interdependence over time stratified by patients' gender revealed specific effects: a moderate correlation between distress in patients and partners, and a transmission of distress from male patients to their female partners. CONCLUSIONS: Our findings provide empirical support for gender-specific transmission of distress in dyads coping with cancer. This should be considered as an important starting point for planning systemic psycho-oncological interventions and conceptualizing further research.

Patient and Informant Views on Visual Hallucinations in Parkinson Disease.

OBJECTIVE Visual hallucinations (VHs) are a very personal experience, and it is not clear whether information about them is best provided by informants or patients. Some patients may not share their hallucinatory experiences with caregivers to avoid distress or for fear of being labeled insane, and others do not have informants at all, which limits the use of informant-based questionnaires. The aim of this study was to compare patient and caregiver views about VHs in Parkinson disease (PD), using the North-East Visual Hallucinations Interview (NEVHI). METHODS Fifty-nine PD patient-informant pairs were included. PD patients and informants were interviewed separately about VHs using the NEVHI. Informants were additionally interviewed using the four-item version of the Neuropsychiatric Inventory. Inter-reliability and concurrent validity of the different measures were compared. RESULTS VHs were more commonly reported by patients than informants. The inter-rater agreement between NEVHI-patient and NEVHI-informant was moderate for complex VHs (Cohen's kappa = 0.44; 95% confidence interval [CI]: 0.13-0.75; t = 3.43, df = 58, p = 0.001) and feeling of presence (Cohen's kappa = 0.35; 95% CI: 0.00-0.70; t = 2.75, df = 58, p = 0.006), but agreement was poor for illusions (Cohen's kappa = 0.25; 95% CI: -0.07-0.57; t = 2.36, df = 58, p = 0.018) and passage hallucinations (Cohen's kappa = 0.16; 95% CI: -0.04-0.36; t = 2.26, df = 58, p = 0.024). CONCLUSION When assessing VHs in PD patients, it is best to rely on patient information, because not all patients share the details of their hallucinations with their caregivers.

Key points for patient safety in dialysis access.

For more than 15 years, patient safety has been an issue in different domains of medicine. There is evidence for this subject and also a great need for information. First, we should be familiar with the basic terminology such as the relationship between adverse events and errors, and understand the variations of error. In patient management, besides skills and knowledge (evidence-based medicine), the ability (competence) of healthcare professionals to act and react in unexpected situations is key to prevent and treat adverse events. Not only healthcare professionals should be involved in the process but also healthy people in a way that they understand and patients in a way that they are actively involved. This paper will show how a more general view of patient safety can and should be implemented in the daily work of caregivers dealing with dialysis access in different aspects. A key factor to advance in this subject is to be open-minded and sensualized for this topic. The reader should get an idea of how an institution can create a culture of safety.

Job satisfaction of Swiss general practitioners with and without proficiency certificate in homeopathy

Introduction: Job satisfaction and therefore wellbeing of physicians is an important issue in high quality and safety of health care provision. The role of additional qualification in complementary medicine (CM) for job satisfaction of general practitioners (GPs), however, has not been explored. This study compared job satisfaction of conventional and homeopathic Swiss GPs. Methods: Participants of the Swiss Family Doctors Conference 2013 and members of the Swiss Association of Homeopathic Physicians participated in the survey. They indicated the extent of job satisfaction on 17 questions covering patient care, work-related burden, income-prestige, personal rewards, and professional relations. Results: Data of n = 125 GPs with homeopathic proficiency certificate and data of n = 143 GPs without any proficiency certificate in CM were analyzed. Overall job satisfaction was high and did not differ between the groups. However, due to lower number of patients per day, homeopathic GPs reported higher satisfaction in relations with patients and with workload, and lower satisfaction with income and in relations with peers compared to conventional GPs. Controlling for further confounding variables (e.g. working hours per week, practice setting), homeopathic GPs reported less satisfaction with their income than their conventional colleagues. Conclusions: Longer consultation time and lower number of patients homeopathic GPs see per day, may allowthem to unfold a deeper and more satisfying relationship with their patients and to lessen the workload. However, this comes along with financial discontent compared to conventional GPs. Certification in homeopathy and increased consultation time, respectively, may represent a way to enhance GPs’ job satisfaction.

Written survey on recently deceased patients in germany and switzerland: how do general practitioners see their role?

BACKGROUND General practitioners (GPs) play an important role in end-of-life care due to their proximity to the patient's dwelling-place and their contact to relatives and other care providers. METHODS In order to get a better understanding of the role which the GP sees him- or herself as playing in end-of-life care and which care their dying patients get, we conducted this written survey. It asked questions about the most recently deceased patient of each physician. The questionnaire was sent to 1,201 GPs in southern North Rhine-Westphalia (Germany) and the Canton of Bern (Switzerland). RESULTS Response rate was 27.5 % (n = 330). The average age of responding physicians was 54.5 years (range: 34-76; standard derivation: 7.4), 68 % of them were male and 45 % worked alone in their practice. Primary outcome measures of this observational study are the characteristics of recently deceased patients as well as their care and the involvement of other professional caregivers. Almost half of the most recently deceased patients had cancer. Only 3 to 16 % of all deceased suffered from severe levels of pain, nausea, dyspnea or emesis. More than 80 % of the doctors considered themselves to be an indispensable part of their patient's end-of-life care. Almost 90 % of the doctors were in contact with the patient's family and 50 % with the responsible nursing service. The majority of the GPs had taken over the coordination of care and cooperation with other attending physicians. CONCLUSION The study confirms the relevance of caring for dying patients in GPs work and provides an important insight into their perception of their own role.

Efficacy of patient-administered mechanical and/or chemical plaque control protocols in the management of peri-implant mucositis. A systematic review

AIM To systematically assess the efficacy of patient-administered mechanical and/or chemical plaque control protocols in the management of peri-implant mucositis (PM). MATERIAL AND METHODS Randomized (RCTs) and Controlled Clinical Trials (CCTs) were identified through an electronic search of three databases complemented by manual search. Identification, screening, eligibility and inclusion of studies was performed independently by two reviewers. Studies without professional intervention or with only mechanical debridement professionally administered were included. Quality assessment was performed by means of the Cochrane Collaboration's tool for assessing risk of bias. RESULTS Eleven RCTs with a follow-up from 3 to 24 months were included. Definition of PM was lacking or heterogeneously reported. Complete resolution of PM was not achieved in any study. One study reported 38% of patients with complete resolution of PM. Surrogate end-point outcomes of PM therapy were often reported. The choice of control interventions showed great variability. The efficacy of powered toothbrushes, a triclosan-containing toothpaste and adjunctive antiseptics remains to be established. High quality of methods and reporting was found in four studies. CONCLUSIONS Professionally- and patient-administered mechanical plaque control alone should be considered the standard of care in the management of PM. Therapy of PM is a prerequisite for the prevention of peri-implantitis.

Taking up national safety alerts to improve patient safety in hospitals: The perspective of healthcare quality and risk managers.

BACKGROUND National safety alert systems publish relevant information to improve patient safety in hospitals. However, the information has to be transformed into local action to have an effect on patient safety. We studied three research questions: How do Swiss healthcare quality and risk managers (qm/rm(1)) see their own role in learning from safety alerts issued by the Swiss national voluntary reporting and analysis system? What are their attitudes towards and evaluations of the alerts, and which types of improvement actions were fostered by the safety alerts? METHODS A survey was developed and applied to Swiss healthcare risk and quality managers, with a response rate of 39 % (n=116). Descriptive statistics are presented. RESULTS The qm/rm disseminate and communicate with a broad variety of professional groups about the alerts. While most respondents felt that they should know the alerts and their contents, only a part of them felt responsible for driving organizational change based on the recommendations. However, most respondents used safety alerts to back up their own patient safety goals. The alerts were evaluated positively on various dimensions such as usefulness and were considered as standards of good practice by the majority of the respondents. A range of organizational responses was applied, with disseminating information being the most common. An active role is related to using safety alerts for backing up own patient safety goals. CONCLUSIONS To support an active role of qm/rm in their hospital's learning from safety alerts, appropriate organizational structures should be developed. Furthermore, they could be given special information or training to act as an information hub on the issues discussed in the alerts.
