Effectiveness of an influenza vaccine programme for care home staff to prevent death, morbidity, and health service use among residents: cluster randomised controlled trial.

ABSTRACT:

Objective

To determine whether vaccination of care home staff against influenza indirectly protects residents.

Design

Pair matched cluster randomised controlled trial.

Setting

Large private chain of UK care homes during the winters of 2003-4 and 2004-5.

Participants

Nursing home staff (n=1703) and residents (n=2604) in 44 care homes (22 intervention homes and 22 matched control homes).

Interventions

Vaccination offered to staff in intervention homes but not in control homes.

Main outcome measures

The primary outcome was all cause mortality of residents. Secondary outcomes were influenza-like illness and health service use in residents.

Results

In 2003-4 vaccine coverage in full time staff was 48.2% (407/884) in intervention homes and 5.9% (51/859) in control homes. In 2004-5 uptake rates were 43.2% (365/844) and 3.5% (28/800). National influenza rates were substantially below average in 2004-5. In the 2003-4 period of influenza activity significant decreases were found in mortality of residents in intervention homes compared with control homes (rate difference -5.0 per 100 residents, 95% confidence interval -7.0 to -2.0) and in influenza-like illness (P=0.004), consultations with general practitioners for influenza-like illness (P=0.008), and admissions to hospital with influenza-like illness (P=0.009). No significant differences were found in 2004-5 or during periods of no influenza activity in 2003-4.

Conclusions

Vaccinating care home staff against influenza can prevent deaths, health service use, and influenza-like illness in residents during periods of moderate influenza activity.

Project description:IntroductionEvery year, up to 1 billion children are victims of violence worldwide. Most child abuse takes place in the context of punishment. The Families First Programme, an adaptation of the Positive Discipline in Everyday Parenting Programme to the West Java context, is a parenting support programme anchored on children's rights that gives parents guidance on child development, parenting and positive discipline practices. This trial will evaluate the effectiveness of the Families First Programme compared with a waitlist control group.Methods and analysisThis is a pragmatic, parallel-group, stratified, cluster-randomised controlled trial. Twenty rural and urban villages in the Cianjur District, Indonesia, involving 720 caregivers of children up to 7 years of age, will be randomised. Villages will receive either a parenting programme consisting of 10 group sessions and four home visits over 3 months and standard community health and social services or just the latter. After completion of the trial period, the programme will be offered to those in the delayed group. Outcome data will be collected before randomisation (baseline), immediately postintervention (3 months postrandomisation) and 6 months later (9 months postrandomisation). The primary outcome will be frequency of physical and emotional punishment as measured by a weighted sum from three self-report items. Primary outcome analysis will use Poisson regression with generalised estimating equations and assess the interaction between intervention and time over baseline and 3 and 9 months postrandomisation assessments. Concurrent process evaluation will be conducted to assess programme satisfaction and facilitators and barriers to the implementation of the programme generalisable to other settings.Ethics and disseminationEthics approval was obtained from McGill University and Universitas Katolik Indonesia Atma Jaya. Results will be published in peer-reviewed journals and presented at scientific conferences and events for decision-makers, including in the participating communities.Trial registration numberNCT03374761.

Project description:BACKGROUND:Physical restraints such as bedrails and belts are regularly applied in German nursing homes despite clear evidence showing their lack of effectiveness and safety. In a cluster-randomised controlled trial, the efficacy and safety of a guideline-based multicomponent intervention programme has been proven. The present study aims to evaluate the effectiveness of two different versions of the original intervention in nursing home residents in four different regions throughout Germany. METHODS/DESIGN:The study is a pragmatic cluster-randomised controlled trial comparing two intervention groups, i.e. (1) the updated original multicomponent intervention programme and (2) the concise version of the updated programme, with a control group receiving optimised usual care. The first intervention group receives an educational programme for all nurses, additional training and structured support for nominated key nurses, printed study material and other supportive material. In the second intervention group, nurses do not receive education as part of the intervention, but may be trained by nominated key nurses who have received a short train-the-trainer module. All other components are similar to the first intervention group. The control group receives the printed study material only. Overall, 120 nursing homes including approximately 10,800 residents will be recruited and randomly assigned to one of the three groups. The primary outcome is defined as the proportion of residents with at least one physical restraint after 12 months follow-up. The use of physical restraints will be assessed by direct observation. Secondary outcomes are the residents' quality of life and safety parameters, e.g. falls and fall-related fractures. In addition, comprehensive process and economic evaluations will be performed. CONCLUSIONS:We expect a clinically relevant reduction in the proportion of residents with physical restraints. It is also expected that the process outcomes of this trial will enrich the knowledge about facilitators and barriers for the implementation of the multicomponent intervention programme.

Project description:Background. Quality staff-resident communication is crucial to promote outcomes in nursing home residents with dementia requiring assistance during mealtimes. Better understanding of staff-resident language characteristics in mealtime interactions help promote effective communication, yet evidence is limited. This study aimed to examine factors associated with language characteristics in staff-resident mealtime interactions. Methods. This was a secondary analysis of 160 mealtime videos involving 36 staff and 27 residents with dementia (53 unique staff-resident dyads) in 9 nursing homes. We examined the associations of speaker (resident vs. staff), utterance quality (negative vs. positive), intervention (pre- vs. post-communication intervention), and resident dementia stage and comorbidities with expression length (number of words in each utterance) and addressing partner by name (whether staff or resident named their partner in each utterance), respectively. Results. Staff (utterance n = 2990, 99.1% positive, mean = 4.3 words per utterance) predominated conversations and had more positive, longer utterances than residents (utterance n = 890, 86.7% positive, mean = 2.6 words per utterance). As residents progressed from moderately-severe to severe dementia, both residents and staff produced shorter utterances (z=-2.66, p = .009). Staff (18%) named residents more often than residents (2.0%; z = 8.14, p < .0001) and when assisting residents with more severe dementia (z = 2.65, p = .008). Conclusions. Staff-resident communication was primarily positive, staff-initiated, and resident-oriented. Utterance quality and dementia stage were associated with staff-resident language characteristics. Staff play a critical role in mealtime care communication and should continue to initiate resident-oriented interactions using simple, short expressions to accommodate resident declining language abilities, particularly those with severe dementia. Staff should practice addressing residents by their names more frequently to promote individualized, targeted, person-centered mealtime care. Future work may further examine staff-resident language characteristics at word and other levels using more diverse samples.
