Siderails as a Measure of Physical Restraint. GERBAR Trial

Aim: to know the perception of older patients and health professionals regarding bedrails using as a method of physical restraint.

Design: quasi-experimental study ("before-after").

Duration: 13 months

Sample:

Two samples will be recruited: one from older patients who are hospitalized at Geriatric Hospitalization Units participating in the study, and the other one including all health professionals working at the 3 hospitals which belong to the Consorci Sanitari de l'Alt Penedès i Garraf.

Sample size:

Being the main objective of the study the estimation of a proportion (proportion of users who consider the siderails as a method of physical restraint), and having a preliminary estimation (65%) of this perception in older patients from a preliminary study, we calculated a sample size of 270 participants, considering a confidence level of 95% with a precision +/- 6%, and a necessary replacement rate of 10%. In the case of healthcare professionals, we calculated a sample size of 85 participants, considering an estimated proportion of 30%, a confidence level of 95% with a precision of +/- 10%, and a necessary replacement proportion of 5%.

Procedures:

In the sample of health professionals, a single online survey questionnaire is expected in month 1 with the purpose of knowing the health professional's perception of siderails as a method of physical restraint.

Once the health professionals' evaluations are finalized, the older patient recruitment will start. A baseline evaluation (interview) will be performed within days 0-2 of admission at the hospitalization unit. In this evaluation, basal data, the perception of bedrails as a method of physical restraint, and a register of patient's desire on using bedrails during their hospitalization will be collected. Then, two follow-up evaluations (days +1 and +2 from baseline evaluation) will be done to record the use of the siderails.

Participants' recruitment:

After the first register of use of bedrails at the Geriatric Hospitalization Units, the researchers will inform the health professionals about the objectives and design of the study, and compliance with the inclusion and exclusion criteria will be verified. If the health professional agrees to participate, the information sheet will be delivered and the informed consent will be collected. All health professionals will complete the survey questionnaire individually, anonymously, and in electronic format.

Older patient's recruitment and their baseline assessment will take place on the same day. The collaborating investigator of the study will invite all those users who undergo the clinical admission interview in the participating hospitalization unit to participate in the study, and within the first two days of admission. Once the study admission criteria have been confirmed, and the participant's informed consent has been obtained, the baseline interview will be carried out. In this interview, the user's perception of the bedrails and their willingness to use them during their hospitalization will be registered. Subsequently, the collaborator will communicate the patient's desire to the nursing team orally and registering the desire at the clinical record.

In the case of participants with Pfeiffer test ≥ 5 errors or a positive result for the Confusional Assessment Method test, a patient's relative or accompanying person will also be interviewed. In the event that the participant is not clinically stable to be interviewed according to the criteria of the interviewer, the interview will be carried out exclusively with the family member or accompanying person.
