Most descriptive studies of psychosocial counseling by US primary care physicians (PCPs) have relied on the PCPs' recollections rather than researchers' observations of actual visit content. The latter approach should yield more accurate measurement of counseling frequency and duration.
Our sample consisted of 308 patients whose scores signified psychological distress on the 28-item General Health Questionnaire. Their visits to 69 community-based PCPs had been audiotaped for an earlier study of the benefits of communication skills training for PCPs. Using those tapes, we identified the disclosure of psychosocial problems by patients and subsequent counseling and psychotropic drug prescribing by their PCPs. We timed counseling and visit lengths. Effects of patient and PCP variables on visit duration and on counseling occurrence and duration were assessed using generalized estimating equations to accommodate the correlation among patients who shared PCPs.
After adjusting for the effects of the communication skills training, we found that PCPs counseled 60% of patients who disclosed psychosocial problems. Given disclosure, counseling probability was lowest for new patients (P <.001); among patients with previous visits, counseling probability was inversely related to the number of visits (P <.001). When provided, counseling had a mean duration of 5.2 minutes. Counseling was associated with a 28% (95% confidence interval, 9%-49%) increase in visit duration after adjustment for the effects of other significant variables. PCPs prescribed psychotropic medications in 30% of visits with disclosure.
PCPs treated psychosocial problems with brief counseling twice as often as with medication. Brief counseling interventions caused small but significant increases in visit durations.
美国初级保健医生(PCP)进行的大多数心理社会咨询描述性研究都依赖于PCP的回忆,而非研究人员对实际就诊内容的观察。后一种方法应能更准确地测量咨询频率和时长。
我们的样本包括308名患者,他们在28项一般健康问卷上的得分表明存在心理困扰。他们对69名社区PCP的就诊进行了录音,用于早期一项关于PCP沟通技能培训益处的研究。利用这些录音带,我们确定了患者心理社会问题的披露情况,以及随后PCP进行的咨询和精神药物处方。我们记录了咨询和就诊时长。使用广义估计方程评估患者和PCP变量对就诊时长、咨询发生情况和时长的影响,以适应共享PCP的患者之间的相关性。
在调整沟通技能培训的影响后,我们发现PCP对60%披露心理社会问题的患者进行了咨询。在披露问题的情况下,新患者接受咨询的概率最低(P<.001);在之前就诊过的患者中,咨询概率与就诊次数呈负相关(P<.001)。当进行咨询时,平均时长为5.2分钟。在调整其他显著变量的影响后,咨询与就诊时长增加28%(95%置信区间,9%-49%)相关。PCP在30%有问题披露的就诊中开具了精神药物。
PCP处理心理社会问题时,进行简短咨询的频率是开药的两倍。简短咨询干预使就诊时长有小幅但显著的增加。
