Survival in end-stage dementia following acute illness
Morrison RS, Siu AL.. JAMA, 2000-07-01
Topic: Risk, prevention and care in population studies
Context Little is known about the prognosis of acutely ill patients with end-stage dementia or about the type of care that these patients receive. If their prognosis is poor, then emphasis should be placed on palliative care for these patients rather than on curative interventions. Objectives To examine survival for patients with end-stage dementia following hospitalization for hip fracture or pneumonia and to compare their care with that of cognitively intact older adults. Design Prospective cohort study with 6 months of follow-up. Setting and patients Patients aged 70 years or older who were hospitalized with hip fracture (cognitively intact, n=59; with end-stage dementia, n=38) or pneumonia (cognitively intact, n=39; with end-stage dementia, n=80) in a large hospital in New York, NY, between September 1, 1996, and March 1, 1998. Main outcome measures Mortality, treatments directed at symptoms, and application of distressing and painful procedures in cognitively intact patients vs those with end-stage dementia. Results Six-month mortality for patients with end-stage dementia and pneumonia was 53% (95% confidence interval [CI], 41%-64%) compared with 13% (95% CI, 4%-27%) for cognitively intact patients (adjusted hazard ratio, 4.6; 95% CI, 1.8-11.8). Six-month mortality for patients with end-stage dementia and hip fracture was 55% (95% CI, 42%-75%) compared with 12% (95% CI, 5%-24%) for cognitively intact patients (adjusted hazard ratio, 5.8; 95% CI, 1.7-20.4). Patients with end-stage dementia received as many burdensome procedures as cognitively intact patients and only 8 (7%) of 118 patients with end-stage dementia had a documented decision made to forego a life-sustaining treatment other than cardiopulmonary resuscitation. Only 24% of patients with end-stage dementia and hip fracture received a standing order for analgesics. Conclusions In this study, patients with advanced dementia and hip fracture or pneumonia had a very poor prognosis. Given the limited life expectancy of patients with end-stage dementia following these illnesses and the burdens associated with their treatment, increased attention should be focused on efforts to enhance comfort in this patient population.

How this study scored 64/100
Published in a top-tier journal, and it is a cohort study following people over time. Scored zero for effect reported and randomised / blinded because the record does not state it. We have no data on journal's citation record, times cited, citations per year, impact for its field and year, cited by studies here, still being cited, senior author's track record, institution's track record and multi-centre collaboration, so those were left out: it earned 37 of the 58 points we could judge it on, which is 64 out of 100.
