SARS-CoV-2 in Nursing Homes: Analysis of Routine Surveillance Data in Four European Countries.

Transmission of SARS-CoV-2 in nursing homes is poorly documented. Using surveillance data of 228 European private nursing homes, we estimated weekly SARS-CoV-2 incidences among 21,467 residents and 14,371 staff members, compared to that in the general population, between August 3, 2020, and February 20, 2021. We studied the outcomes of "episodes of introduction" where one case was first detected and computed attack rates, reproduction ratio (R), and dispersion parameter (k). Out of 502 episodes of SARS-CoV-2 introduction, 77.1% (95%CI, 73.2%-80.6%) led to additional cases. Attack rates were highly variable, ranging from 0.4% to 86.5%. The R was 1.16 (95%CI, 1.11-1.22) with k at 2.5 (95%CI, 0.5-4.5). The timing of viral circulation in nursing homes did not mirror that in the general population (p-values<0.001). We estimated the impact of vaccination in preventing SARS-CoV-2 transmission. Before vaccination's roll-out, a cumulated 5,579 SARS-CoV-2 infections were documented among residents and 2,321 among staff. Higher staffing ratio and previous natural immunization reduced the probability of an outbreak following introduction. Despite strong preventive measures, transmission likely occurred, regardless of building characteristics. Vaccination started on January 15, 2021, and coverage reached 65.0% among residents, and 42.0% among staff by February 20, 2021. Vaccination yielded a 92% reduction (95%CI, 71%-98%) of outbreak probability, and lowered R to 0.87 (95%CI, 0.69-1.10). In the post-pandemic era, much attention will have to be paid to multi-lateral collaboration, policy making, and prevention plans.

A qualitative study of the perception of nursing home practitioners about the implementation of quality indicators for drug consumption in nursing homes.

INTRODUCTION: Nursing homes (NHs) are an ideal environment in which to implement interventions aimed at reducing inappropriate prescriptions. Quality indicators (QIs) may be useful to standardize practices, but it is unclear how they mediate change. In the framework of a quantitative study aimed at reducing the prescription of anticholinergic drugs among NH residents using QIs, we performed a qualitative study to describe the investigators' perception of the utility of QIs. METHODS: Qualitative study using focus group methodology. Focus groups were recorded and transcribed, and analyzed by thematic analysis. Participants were purposefully recruited from among the medical directors of the NHs in the quantitative study. RESULTS: Five medical directors participated in two focus group meetings. The main themes to emerge were: (1) communication is key to introducing new practices and achieving lasting uptake; (2) improved coordination and communication provided useful information to help interpret the quantitative results observed: e.g., participants reported that they were able to obtain contextual and patient-specific information that explained why some prescribers had consistently, but justifiably "poor" performance on the quantitative indicators; (3) negative aspects reported included reluctance to change among prescribers and the tendency to shirk responsibility. CONCLUSION: From the point of view of medical directors of NHs participating in an interventional program to reduce inappropriate prescriptions of anticholinergic drugs, the main factor driving the success of the program was communication, which is key to achieving adherence. Improved communication provides useful insights into the reasons why no quantitative reduction is observed in objective quality indicators.

Risk Indicators Improve the Prescription Quality of Drugs with Anticholinergic Properties in Nursing Homes.

AIM: The objective of this study was to assess the impact of a collaborative therapeutic optimization program on the rate of potentially inappropriate prescription of drugs with anticholinergic properties in nursing homes. METHODS: Quasi-experimental study in 37 nursing homes in France. The intervention included the use of quality indicators for prescriptions combined with educational sessions and dedicated materials for nursing home staff (unlimited access to study material for staff, including nurses, general practitioners, pharmacists). Indicators were calculated based on routine data collected from an electronic pill dispenser system. The primary outcome was the presence of at least one prescription containing ≥1 drug from a list of 12 drugs with anticholinergic properties. A difference-in-differences analysis was conducted at 18 months as well as propensity score weighting to minimize any potential indication bias. A generalized estimating equation model estimated the probability of being prescribed at least one target drug at any time during a 9-month period for each resident. RESULTS: In total, 33 nursing homes (intervention group: n = 10; control group: n = 23) were included, totalling 8137 residents. There was a decrease in the use of drugs with anticholinergic properties over time in both groups, as well as a decline in the intervention group compared to the control group (Odds Ratio: 0.685, 95% CI: 0.533, 0.880; p < 0.01) that was attributable to the intervention. An estimated 49 anticholinergic properties drug prescriptions were avoided by the intervention. CONCLUSION: This study found that an intervention based on indicators derived from routine prescription data was effective in reducing use of drugs with anticholinergic properties prescriptions in nursing homes.

[Impact of animal-assisted interventions on the resident]. / Impact des interventions assistées d'un animal sur le résident.

Animal-assisted interventions are designed for personal well-being. The objective of this study was to evaluate the effectiveness of these interventions in the context of residential facilities for dependent elderly people. Animal-assisted therapy, which can be delivered by trained staff, could be a tool to helpinstitutionalised elderly people cope with loneliness.

Six-month observational follow-up on activities of daily living in people with dementia living in nursing homes after a 6-month group based on either exercise or social activities.

BACKGROUND: Studies have demonstrated changes in activities of daily living after an exercise intervention in people with dementia (PWD) living in nursing homes (NH). However, some discrepancies are shown during follow-up. AIMS: Our objective was to measure activities of daily living (ADL) performance during a 6-month observational follow-up after a 6-month exercise or social activity intervention in PWD living in NH. METHODS: After cluster randomisation, 91 PWD living in NH performed a 6-month structured exercise intervention (n = 44) or a social activity intervention (n = 47). After the intervention, 85 PWD were assessed for post-intervention follow-up. Instrumental and basic activities of daily living (IADL, ADL) were measured at 6-month observational follow-up after the intervention using the Alzheimer's Disease Cooperative Study Activities of Daily Living Inventory for Severe Alzheimer's Disease (ADCS-ADL-sev) scale (scores ranging from 0 to 51, higher is better). RESULTS: Compared to participants in the social activity, those who participated to the exercise intervention had a significant decrease of their ADCS-ADL-sev score (between-group adjusted mean difference: 4.6 points, p = 0.001) with IADL having the most decrease (2.8 points, p = 0.004). DISCUSSION: Unexpectedly, exercisers declined sharply in the performance of ADLs and IADLs, whereas participants in the social intervention group maintained their levels. The potential mechanisms to explain these findings remain still to be elucidated.

Effect of Exercise on Behavioral Symptoms and Pain in Patients With Dementia Living in Nursing Homes.

OBJECTIVES: Examine the effects of a 6-month exercise intervention on neuropsychiatric symptoms, pain, and medication consumption in older people with dementia (PWD) living in nursing homes (NH). METHODS: Ninety-one older PWD living in NH performed a 6-month structured exercise intervention (n = 44) or a social activity intervention (n = 47). Neuropsychiatric symptoms were measured by the neuropsychiatric inventory (NPI), pain was assessed using the Algoplus scale, and dementia-related drug prescriptions were obtained for all participants. RESULTS: Between-group analysis found a nonsignificant difference that could be of clinical relevance: a 4-point difference in the NPI and 1.3-point difference in the reduction of the number of medications favoring exercisers. No significant differences were found for pain, and a trend was found for an increase in medication consumption in the social group. CONCLUSION: Exercise effects did not differ from social intervention effects on neuropsychiatric symptoms, pain, and medication consumption in older PWD living in NH.

The Scale of instantaneous wellbeing: validity in a population with major neurocognitive disorders.

The quality of life (QoL) of people with a neurodegenerative pathology is a major issue in the absence of curative treatment. However, validated tools, suitable for patients with major neurocognitive disorders at a severe stage are rare and time-consuming in routine. The aim of this study is to analyze the validity of convergence and the reliability over time of a visual analog scale of well-being named EVIBE (Échelle d'évaluation instantanée de bien-être). The correlation between the EVIBE and another quality of life scale, the Qol-Ad was studied. The correlation with other scales expected to vary with QoL was also studied with the EQ-5D for the measurement of the state of health felt and the NPI-ES for the measurement of behavioral disorders. The EVIBE was administered twice, a few minutes apart, to measure its reliability over time. One hundred and thirty-five patients with Alzheimer's disease or a related disorder were recruited. The results indicated a significant correlation with Qol-AD (r=0.54, p< 0.001). The correlation remained significant when the Mini mental state examination was less than 10 (r=0.39, p=0.05). Correlations between EVIBE and EQ-5D and NPI-ES indicated more mixed results with significant correlation only for the analog part of the EQ-5D (r=0.34, p=0.007). The comparison between the two EVIBEs a few minutes apart showed a satisfactory agreement (r=0.52, p> 0.001). This study shows that EVIBE present a good convergence validity and a good reliability over time to measure the QoL of patients with neurodegenerative pathology even at severe stages of the disease. The scale allows a direct and rapid assessment of the QoL of patients in routine.

Analgesic consumption in nursing homes: observational study about 99 nursing homes.

Few analgesics' studies in nursing homes are available. Quantitative and qualitative analgesic consumption evaluation in nursing homes in 2012. Multicenter, descriptive, retrospective and observational study about French Korian Nursing homes' residents, using Medissimo solution, and under at least one analgesic treatment during 2012. We considered as chronic prescription a duration greater than or equal to 28 days and as short prescription a duration less than 28 days. Population studied is 10.818 residents. 62% consumed at least one analgesic, 51% had a chronic analgesic consumption, 11% had a short analgesic consumption and 25% had an analgesic consumption both short and chronic. 47% residents under analgesic treatment received at least one prescription of painkillers "when require". Short prescription represents 19% of analgesic prescriptions: 57% are level 1 only, 20% are level 3 only and 16% are level 2 only. Chronic prescription represents 81% of analgesic prescriptions: 68% are level 1 only, 13% are level 2 only and 5% are level 3 only. 18 INNs were prescribed in nursing homes: paracetamol in 74% of cases, tramadol in 13% of cases, opioids and NSAIDs in 8% of cases. Our study reveals an analgesic consumption sometimes inappropriate with respect to paracetamol, tramadol and NSAIDs consumptions in addition to an overuse of fentanyl patch consumption. Residents in nursing homes are high analgesics consumers, often chronic. Paracetamol is the reference molecule.
