Abstract
This quasi- experimental research with two group, pretest - posttest design, aimed to compare length of stay and relapse among schizophrenic patients with alcohol use of the experimental group receiving primary nursing system and the control group receiving usual nursing care. Samples were 30 schizophrenic patients with alcohol use, admitted in Somdet Chaopraya Institute of Psychiatry. Sample who met inclusion criteria, were matching paired by sex, illness duration, and prescribed psychotic medication and then equally assigned into an experimental and a control groups. Research instruments included the primary nursing system manual, length of stay (LOS) records, and relapse using the Brief Psychotic Rating Scale (BPRS). The content validity of the manual was examined by 5 experts with CVI = 85. The Cronbach’s Alpha reliability of the relapse based on the BPRS was .70. Data were analyzed by using the independent t-test. Findings showed that there was no significant difference of the average length of stay between the experimental group ( =33.98, SD=18.21) and the control group ( =36.44, SD =14.14). Relapse after 1 month or the BPRS of the experiment group ( =21.53, SD = .3.79) was statistically significant lower than those of the control group ( =27.47, SD = 5.26), at the level of p= .05. Findings suggested that the primary nursing system could be used in schizophrenic patients with alcohol use to improve the quality of psychiatric nursing service. The competencies of primary nursing care team should be built and long-term follow up research should be conducted.
