Anthierens, 2009 [36] | Belgium | Qualitative | 33 NH nurses, in 5 NHs | Focus group and face-to-face interviews exploring BZRA use in NH, perceived role of nurses and their attitudes and feelings | Not reported | Different themes and subthemes: Nurses individual attitudes and perceptions: -Routine approach -Nurse as ‘sleep guardian’ Pharmacological knowledge Organisational factors: -Traditional doctor-nurse relationship -Organisational requirements -Smooth running of the NH Team meetings |
Bourgeois, 2014 Study A [37] | Belgium | Quantitative, BZRA deprescribing feasibility study, uncontrolled | 135 NHRs in 5 NHs | GPs and NHRs willingness to deprescribe Feasibility of deprescribing | BZRA discontinuation | Willingness for discontinuation: GPs refused deprescribing for 71 NHRs Reasons: - Unmotivated patient: 40 - Previous attempt failed: 13 - Other reasons (too old): 9 - Medical cause of sleeplessness: 8 - BZRA not indicated for sleep problems: 6 - Psychiatric history: 5 - Discontinuation started before inclusion possibility: 4 - Stopped BZD but switched to something else: 2 - Discontinuation but no agreement to start in study: 2 13 NHRs out of 51 refused Main reason: reluctance towards change Feasibility of discontinuation: Of 38 NHRs, 66.0% were successful in completely discontinuing BZRA use at 8 months The reasons why NHRs were not successful in their discontinuation was because of sleep problems during the discontinuation (n=6/13) and overall loss of motivation (n= 5/13) |
Bourgeois, 2014 Study B [38] | Belgium | Quantitative cross-sectional study: GP and nurse questionnaire | 25 GPs and 16 nurses in 5 NHs | Initiation, indication and previous attempts to stop chronic BZRA use Benefit and harm of BZRA use Willingness to stop BZRA use Resident-specific barriers General attitudes towards BZRA discontinuation | BZRA discontinuation | Previous attempts The GPs and the nurses indicated that they had already attempted a withdrawal in the past in 26% and 12% of the residents, respectively In general, chronic BZRA use was perceived as effective, and only few adverse effects were noted Willingness to stop GPs and nurses indicated willingness to stop chronic BZRA use in respectively 33 and 21% of NHRs Resident-specific barriers most common barriers among the GPs were: -Fear of resistance from the resident -Preference of a pharmacological treatment above a non-pharmacological treatment -Fear that in these resident initial problems would come back -Fear of an increase in the care burden for the staff -Perception that change is not necessary as long as the resident functions well -Fear of withdrawal effects. Among the nurses, the most common barriers were: -Fear that the residents’ initial problems would come back -Preference for a pharmacological treatment -Conviction that change is not necessary as long as the resident functions well. General attitudes The most common attitudes among both GPs and nurses were: -The longer the resident takes the medication, the more difficult it is to stop. -Old age of a resident makes it difficult and unnecessary to stop. -Help of other care professions, such as a psychologist and a pharmacist, are not really necessary. -Alternative strategies are more time-consuming -Rhythm of a nursing home with strict bedtimes also limits possibilities for discontinuation. Nurses agreed and GPs disagreed on the statements that there is little knowledge on alternative strategies to cope with problems when stopping BZDs and that there is little scientific information available for stopping. |
