Biosocial factors and their role in the work of emergency psychiatric aid teams
Frequency analysis of the causes for calling emergency psychiatric medical teams (EPMTs), made during 2016 in Cheboksary, the Chuvash Republic, was carried out, it was necessary to predict the daily number of EPMT calls, to organize and improve the efficiency of EPMTs. The aim of the research is to identify regularities in time series in calling EPMTs. The material of the study was the data obtained from mapping extracts of accounting form N 114/u, namely: the patient's age, date, time and duration of the call, the diagnosis by ICD-10, effectiveness and outcome of the medical aid provided. Time series in frequencies of the calls were grouped according to ICD-10 disease classes by days, weeks and months. We calculated the number of calls to one patient, the true number of patients by disease classes during the study period, the average number of visits per patient. Two thousand nine hundred calls (92,7%) accounted for five classes of ICD10: F00-F29 (30,3%), F60-F69 (25,8%) and Z00-Z99 (18,1%). The mean age of patients was 39,3±26,7 years old. The oldest were patients with diagnoses related to the classes of diseases F50-F59 (59,5±27,6 years) and F30-F39 (56,0±23,0 years). The number of calls for such classes of diseases as F20-F29, F10-F19, F60-F69 and F60-F69 for this age group averaged 58.7%. There were significantly more men in this age group – 57,5% and 38,1% respectively (p < 0,001, z-test). There were more women aged 60-74 and 75 years old and older (p < 0,001, z-test). The maximum number of repeated calls was in class F20 – F29-192 patients (492 calls, 51,9%). Out of 492 calls in 152 cases medications were applied, in 340 (69,1%) cases hospitalization was needed. The analysis of circadian time series revealed two peaks in calls. In the period from 9.00 to 16.00 calls were made mainly by women (p = 0,0044, z-test). At 18.00 – 21.00 – those were made by men (p = 0,0095, z-test). The frequency of calls in these time intervals made 17.4 and 16.9%, respectively, and significantly exceeded the average probability daily rate (p < 0,001, z-test), which makes 12,5% when dividing the day (100%) into eight intervals. No peculiarities in weekly rhythms in the number of calls were established. The most troublesome month for men was January – a statistically significant increase in the number of calls in comparison with the average-probable rate.
