Staging dementia based on caregiver reported patient symptoms: Implications from a latent class analysis.

ABSTRACT: BACKGROUND:Tailoring interventions to the needs of caregivers is an important feature of successful caregiver support programs. To improve cost-effectiveness, group tailoring based on the stage of dementia could be a good alternative. However, existing staging strategies mostly depend on trained professionals. OBJECTIVE:This study aims to stage dementia based on caregiver reported symptoms of persons with dementia. METHODS:Latent class analysis was used. The classes derived were then mapped with disease duration to define the stages. Logistic regression with receiver operating characteristic curve was used to generate the optimal cut-offs. RESULTS:Latent class analysis suggested a 4-class solution, these four classes were named as early (25.9%), mild (25.2%), moderate (16.7%) and severe stage (32.3%). The stages based on the cut-offs generated achieved an overall accuracy of 90.8% compared to stages derived from latent class analysis. CONCLUSION:The current study confirmed that caregiver reported patient symptoms could be used to classify persons with dementia into different stages. The new staging strategy is a good complement of existing dementia clinical assessment tools in terms of better supporting informal caregivers.

Project description:Patient-reported outcomes such as health-related quality of life (HRQOL) are impaired in cirrhosis due to under-treated mood and sleep disorders, which can adversely impact their caregivers. Mindfulness-based stress reduction (MBSR) can improve patient-reported outcomes (PRO) in non-cirrhotic patients but their impact in cirrhosis is unclear. To evaluate the effect of MBSR and supportive group therapy on mood, sleep and HRQOL in cirrhotic patients and their caregivers.Cirrhotic outpatients with mild depression (Beck Depression Inventory (BDI)>14) on screening with an adult caregiver were enrolled. At baseline, BDI, sleep (Pittsburgh sleep quality index PSQI, Epworth Sleepiness Scale, ESS), anxiety (Beck Anxiety inventory) and HRQOL (Sickness Impact Profile, SIP) for both patients/caregivers and caregiver burden (Zarit Burden Interview Short-form, ZBI-SF and perceived caregiver burden, PCB) and patient covert HE(CHE) status were measured. Patients who had BDI>14 at baseline, along with their caregivers then underwent a structured MBSR program with four weekly hour-long group sessions interspersed with home practice using CDs. After the last group, all questionnaires were repeated.20 patient/caregiver dyads were included. All patients were men (60±8 years MELD 12.9±5.7, 14 prior hepatic encephalopathy (HE)) while most caregivers (n=15) were women (55±12 years, 23±14 years of relationship, 65% spouses). There was no change in patient BDI between screening and baseline (20.1±11.2 vs. 19.0±10.6, P=0.81). All dyads were able to complete the four MBSR+supportive group therapy sessions. There was a significant improvement in BDI (19.0±10.6 vs.15.6±8.2 P=0.01), PSQI (7.2±3.7 vs. 5.5±3.7, P<0.001) and overall HRQOL (25.0±13.2 vs. 17.7±14.0,P=0.01) but not in anxiety or CHE rates in patients. Similarly caregiver burden (ZBI-SF13.0±9.0 vs. 9.8±6.9,P=0.04, Perceived burden 72.1±29.9 vs. 63.0±14.5,P=0.05) and depression reduced (BDI 9.1±7.8 vs. 5.9±6.0,P=0.03) while caregiver sleep quality (7.2±3.7 vs. 5.5±3.7,P<0.001) improved. Prior HE did not affect PRO change after MBSR+supportive groups but the ZBI-SF of caregivers taking care of HE patients improved to a greater extent (delta -1.1±6.5 vs. 7.4±5.3 HE, P=0.04).A short program of mindfulness and supportive group therapy significantly improves PRO and caregiver burden in cirrhotic patients with depression. This non-pharmacological method could be a promising approach to alleviate psychosocial stress in patients with end-stage liver disease and their caregivers.
