STRIPPS is an etiologic, multi-center cohort study in the Ile-de-France region aiming to study better understands the complex relationship between the work organization, the stress ant and the caregiver fatigue and infectious risk in the hospital departments.
It will be conducted in 5 volunteer hospitals, with 7 to 8 hospital departments selected at random in each center and meeting eligibility inclusion criteria. The envisaged recruitment is approximately 20 staff per hospital department, enabling a total of about 150 staff to be included per center, totaling 750 surveyed caregivers.
The five voluntary centers will designate at least one local correspondent or referent among the hygiene team, the human resources (HR) department and the department of medical information system (DMI). The hygiene referent is the privileged correspondent. He will be part of the scientific committee and will help the investigators in the organization of the study within the hospital departments that will be drawn to participate. The HR and DMI referents are appointed to facilitate the collection of anonymous and aggregated data from the HR and PMSI databases planned for the study.
After obtaining regulatory authorizations, the eligible hospital departments of each hospital center will be drawn at random. Prior to the draw, hygiene referents of each hospital will prepare a list with all eligible hospital departments. Hospital departments will be selected using simple random sampling without replacement as follows in each list, the services will be numbered from 1 to n and 8 numbers between 1 and n will be chosen randomly using a computer. It will have a total of 5 lists (one list per hospital center) and 8 randomly selected numbers per list for a total of 40 randomly selected services. Similarly, visit days and survey start schedules will be drawn at random for the passage of an epidemiologist investigator recruited by the coordinating team. Two survey dates, between one Monday and one Friday of each week, and one survey start schedule, will be drawn at random for each work shift in every participating hospital department, during the entire inclusion period. Information meetings with the staff of the selected participating hospital departments and the communication by display will be organized by the investigators. A 15-day period will be left between the last information meeting held in the service and the closest date drawn for the start of the inclusion visits.
Based on a prospective data collection and using a qualitative-quantitative approach this study will provide some elements to better understand the complex relationship between the work organization, the stress and the caregiver fatigue, and infectious risk in the hospital departments (for patients and caregivers). This is an approach that relies on a conceptual model with several hypotheses to test. The conceptual diagram envisaged in our study has been based on the James Reason's model of accident causation. Indeed, it considers a multi-level interrelation of many factors ranging from organizational climate root causes to infectious risk. This equally includes contributory factors related to caregivers themselves, the care team, work environment as well as immediate causes related to care practices. Thus, for example, the infectious risk such as blood exposure accidents (for caregivers) or healthcare-associated infections (for patients) could be explained by several relationships between a wide range of factors: behavioral changes in care workers such as a decreased adherence with infection control measures as hand hygiene, stress and fatigue of caregivers, an excessive workload, a high nurse turnover or their absenteeism, the work schedules, as well as, by individual factors such as, the work experience, age, and the organizational climate as root causes.
In this research the following factors will be taken into account:
* at the organizational level: the type and size of hospital departments (in number of beds and in number of caregivers), the hourly organization of the staff, the number of caregivers by professional category for each shift in 24h;
* at the hospital department level: nurse absenteeism and turnover rates, safety culture, healthcare-associated infections rates, the rate of blood exposure accidents among caregivers, hand hygiene compliance rates;
* at the level of caregivers: age, sex, personal situation, number of young children, occupation, the position held, work experience, work schedules, stress and fatigue levels, blood exposure accidents, excessive work-related commitment, the social support from coworkers and from supervisors, current state of health, absences due to health reasons including absences due to accidents at work or for work-related illness, etc.
