To examine changes in patients' and caregivers' understanding of prognosis with progression of the patient's illness.
Community-dwelling persons 60 years of age and older who were seriously ill with cancer, congestive heart failure, or chronic obstructive pulmonary disease and their caregivers were interviewed every 4 months and more frequently with a decline in the patient's status for up to one year. We examined responses to, "If you had to take a guess, how long do you think that (you/the patient) might have to live?" at baseline and at the interview closest to death.
Among 218 patients, 87 died within 1 year. At their initial interview 46% were uncertain about their life expectancy (LE) and 9% believed LE was 1 year or less; at their final interview, 55% were uncertain and 17% believed LE was 1 year or less. At the caregiver's initial interview, 29% were uncertain about the patient's LE and 20% believed LE was 1 or less; at their final interview, 30% were uncertain and 34% believed LE was 1 year or less. Among those interviewed within 30 days of the patient's death, 31% of patients and 52% of caregivers believed LE was 1 year or less. Patients' estimates of the LE did not differ according to their diagnosis.
There was little change in prognostic awareness over time. Even close to death, a large proportion of patients and caregivers were uncertain about prognosis, and few believed the patient had a limited life expectancy. Whether or not patients should know their prognosis is the subject of active debate; the persistence of prognostic misperception suggests that prognostic awareness may be difficult to change.
研究随着患者病情进展,患者及其照料者对预后理解的变化。
对60岁及以上患有严重癌症、充血性心力衰竭或慢性阻塞性肺疾病的社区居民及其照料者每4个月进行一次访谈,若患者病情恶化则增加访谈频率,持续一年。我们调查了在基线期和最接近死亡的访谈中,对于“如果你必须猜测一下,你认为(你/患者)还能活多久?”这个问题的回答。
218名患者中,87人在1年内死亡。在初次访谈时,46%的患者对自己的预期寿命(LE)不确定,9%的患者认为LE为1年或更短;在最后一次访谈时,55%的患者不确定,17%的患者认为LE为1年或更短。在照料者初次访谈时,29%的人对患者的LE不确定,20%的人认为LE为1年或更短;在最后一次访谈时,30%的人不确定,34%的人认为LE为1年或更短。在患者死亡前30天内接受访谈的人中,31%的患者和52%的照料者认为LE为1年或更短。患者对LE的估计不因诊断而异。
随着时间推移,预后意识变化不大。即使接近死亡,仍有很大比例的患者和照料者对预后不确定,很少有人认为患者预期寿命有限。患者是否应该知道自己的预后是一个正在激烈讨论的话题;预后误解的持续存在表明预后意识可能难以改变。
