Abstract
This work was conducted at Shebin El-Kom (Menoufia governorate) tertiary care hospitals (Menoufia University hospitals, Shebin El Kom Teaching hospital and National Liver Institute) to investigate psychosocial work stress and its impact on medical residents working at these hospitals.
All the medical residents that worked at the three studied tertiary care hospitals (670 residents) were targeted to the study. after application of the inclusion and exclusion criteria, 270 medical residents were excluded as they were residents for less than 1 year. The remaining 400 medical residents were invited to participate in this study but 55 disagreed to participate. The final sample size of this study was 345 participants, with a response rate of approximately 86.3% (345/400). After the exclusion of pilot study sample size (30 subjects), the total sample size was 315 medical residents. The participants were distributed over all hospitals’ departments including medical departments (internal medicine, psychiatric and pediatric departments), surgical departments (general and special Surgeries), intensive care units and other departments.
All participants were interviewed after the work shift at the administration departments of the studied hospitals using a predesigned questionnaire about the following socio-demographic data (age, gender, smoking, marital status, exercise performance) and occupational history (resident category, number of working years, name of hospital, name of department, number of patients per day, average work hours /day, work days/week, day off after shift, taking break during work hours, number of night shifts per week). Also, work stress was assessed by Effort-Reward Imbalance (ERI) model. All participants were subjected to The Middlesex Hospital Questionnaire aiming at examining the psychological effects of occupational stress on medical residents.
The following results were obtained:
Most of the studied participants were married non-smoker females aged from 25-30 years. More than half of the participants (57.1%) did not perform exercise. Approximately half of the participants (51.4%) worked at Teaching hospital while the other half worked at Menoufia University hospitals (33.3%) and National liver institute (15.3%). Most of them belonged to medical departments (71.4%) as juniors and mid seniors (53%). The participants (74.3%) worked more than 5 days/week and 61% didn’t take break during work hours. The number of night shifts ranged from 1-5/ week. Work stress was prevalent among residents working at Menoufia tertiary care hospitals. The medical residents (82.9%) suffered from work stress as indicated by Effort/reward ratio > 1 and 65.7% of them had high over commitment. This result imply that immediate intervention programs are needed to overcome these problems and to keep residents physically and mentally healthy. Work stress was significantly associated with lower mean age (26.6± 1.53) and smoking. Among the studied participants, work stress was significantly prevalent among medical residents working in medical departments, with lower mean of work years, higher mean of work hours/day, taking more night shifts/ week and among those who did not take break during work hours. High over commitment was significantly associated with lower mean age, single females and non-smokers. High over commitment was significantly prevalent among juniors and mid seniors working in medical departments, with lower mean of work years, higher mean of work hours/day, dealing with a higher number of patients per day and with taking more night shifts/ week. Work stress was significantly associated with higher phobic anxiety and depression (P=0.027 and P= 0.004; respectively). Among the studied participants, high over commitment was significantly associated with anxiety, obsessionality, somatic concomitants of anxiety and depression. Anxiety mean score was significantly higher in females, non-smokers and in those who did not perform exercise, medical residents who worked at Menoufia University hospitals and National liver institute, in medical departments and among residents who did not take day off after night shift. Phobic anxiety mean score was significantly higher in female, nonsmoker medical residents, in medical residents who worked in medical departments and among those who did not take break during work hours. Obsessionality mean score was significantly higher in females, single and non-smoker medical residents, in medical residents who worked in medical departments. Among the studied participants, the mean score of somatic concomitants of anxiety was significantly higher in female and nonsmoker medical residents, in medical residents who worked at National liver institute and those worked in medical departments. Depression mean score was significantly higher in females, single and non-smokers. Also, depression mean score was significantly higher in junior and mid senior medical residents who worked in medical departments and among those who didn’t take break during work hours.
Hysteria mean score was significantly higher in married medical residents, there was a significant positive correlation between the number of work years and hysteria. Also, hysteria mean score was significantly higher in medical residents who didn’t take break during work hours.
