introduction
Introduction
  • According to the Special Committee on Aging (2001):
    • As many as 52 million Americans are informal caregivers.
    • Nearly three-quarters of informal caregivers are women, most typically married women in her mid-40s to mid-50s employed full-time.
    • Population trends forecast an increase in informal caregiving needs.
introduction1
Introduction
  • Assistive device use and environmental interventions can be effective in reducing home care costs and in maintaining independence in frail elders.
    • (Mann, Ottenbacher, Fraas, Tomita, & Granger, 1999).
  • Electronic technologies have been shown to be effective in reducing caregiver burden
    • (Kart, Kinney, Murdoch, & Ziemba, 2002).
identifying caregivers
Identifying Caregivers
  • Caregivers provide support to someone who needs help. 
    • It doesn’t matter how many hours per week are spent providing support. 
    • Caregivers may live with the person they are caring for, providing assistance with daily needs, or may visit the person weekly or call regularly. 
  • Being a caregiver involves an investment in time, energy and support.
definitions informal caregiving caregiver burden caregiver burnout
Definitions: Informal Caregiving, Caregiver Burden, Caregiver Burnout
  • Informal or lay caregiving
    • The act of providing assistance to an individual with whom the caregiver has a personal relationship.
  • Caregiver burden (Kasuya, Polgar-Bailey, & Takeuchi, 2000)
    • Defined as the strain or load borne by a person who cares for an elderly, chronically ill, or disabled family member or other person.
      • It is a multidimensional response to physical, psychological, emotional, social, and financial stressors associated with the caregiving experience.
    • The caregiver's perception of the burden, rather than the perception of other family members or healthcare providers, determines the impact on his or her life.
definitions caregiver burnout
Definitions: Caregiver Burnout
  • Caregiver burnout
    • The progression of caregiver burden to the point where the experience is no longer a viable or healthy option for either the caregiver or the person receiving care.
  • Goal of Health Care Providers
    • Lessen the demands of caregiving, prevent caregiver burden
      • If not possible prevent progression to burnout
prevalence of caregiver burden and burnout
Prevalence of caregiver burden and burnout
  • The prevalence of caregiver burden has been described in multiple surveys.
  • Results of a 1992 study by the Carers National Association indicated that:
    • One of every two caregivers had financial burdens
    • Two of every three were in ill health themselves
effects of caregiving
Effects of Caregiving
  • Home care of chronically ill persons has received considerable attention in recent years.
    • However, difficulties experienced by caregivers often are considered only after the signs of burnout are apparent.
  • Family members and other providers often accept responsibility for the care of those with chronic health needs.
    • Typically, they do this for emotional and economic reasons, not because they are proficient at, or feel comfortable with, the type of care required.
  • They frequently expect or are expected to assume the role of caregiver without regard for the possible emotional, physical, and financial consequences.
background
Background
  • Caregiving has both negative and positive impacts.
  • Caregivers who perceive the positive rewards will be less likely to suffer the negative effects on health and financial resources, while maintain family satisfaction (Carruth, Tate, Moffett, & Hill, 1997).
  • Interventions should include the positive aspects of caregiving to be most effective.
lazarus stress appraisal coping model
Lazarus’ Stress-Appraisal-Coping Model
  • Useful in understanding caregiver burden (Lazarus & Folkman, 1984).
    • Psychological stress occurs when demands or conflicts exceed resources.
    • Reaction to stress subject to individual’s “cognitive appraisal”.
      • Includes both primary and secondary forms of appraisal.
      • Reappraisal is a continual process, can determine the caregiver’s sense of mastery.
smart home
Smart Home
  • “Wireless Caregiving” (Coughlin, 1999).
    • Allows communication and health monitoring from a distance, frees caregiver to partake in other activities.
    • Could prolong the ability of older adults to live at home and avoid institutionalization.
  • Includes the Personal Assistance Security System (PASS).
    • Personal assistance security systems can notify a caregiver if a fall has occurred.
    • The ability of the elder to notify the caregiver in times of distress can reduce worry and stress for both parties.
literature review summary
Literature Review: Summary
  • Rationale for intervention based on the Stress-Appraisal-Coping model, caregiving, assistive technology, and home modification literature.
  • Based on the literature, it is predicted that:
    • Use of the PASS by frail elders will assist the caregiver in:
      • Feeling mastery or control over the situation.
      • Enhancing social support.
research questions
Research Questions
  • Will the treatment group (care recipients who have a PASS) maintain their status while the control group will decline?

  • Will the combination of the PASS with e-mail benefit users the most?
  • Which segment of caregivers will benefit most?
  • What is the subjective evaluation of PASS and e-mail use for caregiving?
methods study design

Intervention group allowed to keep system at study’s conclusion.

Installation.

1 day installation, 3 1-hour training sessions or more as needed to care recipients and caregivers.

Ongoing technical support via principal investigator, project staff.

psychosocial outcome measures
Psychosocial outcome measures
  • Zarit Burden Interview (ZBI).
    • 29 item self-report inventory of burden.
  • Center for Epidemiological Studies Depression (CES-D) Inventory.
    • Measures depression experienced in the past week.
  • Picot Caregiver Rewards Scale.
    • Measures positive feelings and outcomes related to the caregiving experience.
results
RESULTS
  • No statistical differences were noted between the treatment (n =31) and control (n = 19) caregiver groups at initial assessment
  • Care recipient age (Treatment, M = 72.10, SD = 6.00; Control, M = 77.74, SD = 8.34; t = 2.78, p = .008) and race (Treatment, Minority = 25%, Control, Minority = 5.3%; X2 = 3.554, p = .030) were significantly different.
research question 3
Research Question 3
  • Will the combination of the PASS with e-mail use benefit caregivers the most?
rq4 which segment of caregivers will benefit most
RQ4: Which segment of caregivers will benefit most?
  • Depression
    • Non e-mail users increased in depression.
    • Caregivers who did not use the PASS or e-mail had the worst outcome.
  • Burden
    • Caucasian caregivers who provided fewer than 3 hours of care per week who used e-mail had a decrease in burden.
    • Burden declined even further in those individuals who were employed out of this group
  • Caregiving Satisfaction
    • Results showed that the PASS made a difference in caregiving satisfaction for Caucasian participants.
    • The use of PASS could maintain these users caregiving satisfaction.
rq5 caregiver and care recipient subjective evaluation
RQ5: Caregiver and Care Recipient Subjective Evaluation
  • Caregivers
  • 100% of the caregivers (n = 31) evaluated the PASS positively.
  • 94% (n =47) reported they would worry less about the care recipient’s living alone following installation of the PASS
  • Positive responses re: e-mail from 100% of users (n = 14). Used most frequently to keep in touch (pictures, humorous items).
  • Care recipients
  • 83.9% (n = 26) reported feeling safer in the home after installation of the PASS.
  • 82.4% (n = 25) reported that e-mail is very important in their lives .
discussion effectiveness
Discussion: Effectiveness
  • The combination of PASS and e-mail use is the most effective way to prevent a significant increase in caregiver depression and burden.
  • Technology interventions (PASS and e-mail) appear to have no impact on caregiving satisfaction.
discussion minority caregivers
Discussion: Minority Caregivers
  • Caregiving satisfaction declined among all participants, especially among minority caregivers.
  • The decrease in burden among minority caregivers is significantly different from Caucasians.
    • The technology did not have an impact on these participants.
    • There appears to be another factor(s) affecting this group.
discussion targeting the intervention
Discussion: Targeting the Intervention
  • The benefits of the PASS can be maximized by targeting specific caregivers. Two specific segments were identified:
    • Caregivers with an income of at least 20K, healthy, and employed.
    • Caregivers who are Caucasian, provide care less than 3 hours, and not employed, but would like to spend more time helping the care recipient.
  • The benefits of e-mail is maximized by targeting specific caregivers.
    • Income of at least 20K.
    • Caregivers who are Caucasian, and provide care less than 3 hours.
clinical implications
Clinical Implications
  • Practical and low cost technology, such as e-mail and PASS has a positive impact for certain caregivers. Use of these technologies should be encouraged to enhance the well-being of caregivers.
  • Technology interventions combined with counseling appear to be especially effective in reducing caregiver depression (Eisdorfer, et al., 2003)
