134 ADULT SAFEGUARDING, HUMAN RIGHTS AND PEOPLE LIVING WITH DEMENTIA IN NURSING HOMES: CO-PRODUCING RECOMMENDATIONS FOR BEST PRACTICE

Background

People living with dementia (PLwD) in nursing homes have the right to be safe and to live a life free from harm and abuse; all persons are entitled to this right, regardless of their circumstances or where they live. PLwD are at greater risk of abuse and neglect than those without a diagnosis. Such abuse often goes unnoticed, because dementia may affect a person’s ability to recognise abuse or to report it. In 2021, the Alzheimer Society of Ireland’s Irish Dementia Working Group (IDGW) commissioned the development of a briefing paper to outline the key issues relating to upholding the human rights and safeguarding of PLwD in nursing homes including concrete recommendations for policy and practice.

Methods

A scoping review of the existing literature on this topic was carried out. This was supplemented by adopting a snowball strategy to identify additional relevant literature. Three co-design online sessions were convened with members of the IDWG in order to discuss and agree on the general content and members also provided suggestions for additional research or policy papers that should be included. Co-design sessions were also used to brainstorm and reach a consensus as a group on recommendations.

Results

This project identified a number of specific risk factors for PLwD, including organisational abuse, the need to move towards a restraint-free environment, addressing barriers to reporting of abuse and promoting agency and autonomy within safeguarding processes. A number of policy and legislative gaps in our current adult safeguarding framework were identified making it more difficult to adequately protect PLwD in nursing homes.

Conclusion

22 recommendations for best practice were developed by the IDWG for nursing home service providers (public and private), health and social care practitioners, policymakers, the Department of Health, HIQA and political representatives in order to collectively advocate for meaningful change.

Modelling Thirty-day Mortality in the Acute Respiratory Distress Syndrome (ARDS) in an Adult ICU

Variables predicting thirty-day outcome from Acute Respiratory Distress Syndrome (ARDS) were analysed using Cox regression structured for time-varying covariates. Over a three-year period, 1996–1998, consecutive patients with ARDS (bilateral chest X-ray opacities, PaO2/FiO2 ratio of <200 and an acute precipitating event) were identified using a prospective computerized data base in a university teaching hospital ICU.

The cohort, 106 mechanically ventilated patients, was of mean (SD) age 63.5 (15.5) years and 37% were female. Primary lung injury occurred in 45% and 24% were postoperative. ICU-admission day APACHE II score was 25 (8); ARDS onset time from ICU admission was 1 day (median: range 0-16) and 30 day mortality was 41% (95% CI: 33%-51%). At ARDS onset, PaO2/FiO2 ratio was 92 (31), 81% had four-quadrant chest X-ray opacification and lung injury score was 2.75 (0.45). Average mechanical ventilator tidal volume was 10.3 ml/ predicted kg weight. Cox model mortality predictors (hazard ratio, 95% CI) were: APACHE II score, 1.15 (1.09-1.21); ARDS lag time (days), 0.72 (0.58-0.89); direct versus indirect injury, 2.89 (1.45-5.76); PaO2/FiO2 ratio, 0.98 (0.97-0.99); operative versus non-operative category, 0.24 (0.09-0.63). Time-varying effects were evident for PaO2/FiO2 ratio, operative versus non-operative category and ventilator tidal volume assessed as a categorical predictor with a cut-point of 8 ml/kg predicted weight (mean tidal volumes, 7.1 (1.9) vs 10.7 (1.6) ml/kg predicted weight). Thirty-day survival was improved for patients ventilated with lower tidal volumes.

Survival predictors in ARDS were multifactorial and related to patient-injury-time interaction and level of mechanical ventilator tidal volume.

A phase II study evaluating the efficacy of zoledronic acid in prevention of aromatase inhibitor-associated musculoskeletal symptoms: the ZAP trial

PURPOSE

Aromatase inhibitor-associated musculoskeletal symptoms (AIMSS) are common adverse events of AIs often leading to drug discontinuation. We initiated a prospective clinical trial to evaluate whether bisphosphonates are associated with reduced incidence of AIMSS.

METHODS

In the single-arm trial, the Zoledronic Acid Prophylaxis (ZAP) trial, we compared the incidence of AIMSS against historical controls from the Exemestane and Letrozole Pharmacogenomics (ELPh) trial. Eligible women were postmenopausal with stage 0-III breast cancer planning to receive adjuvant AIs. AIMSS was assessed using the Health Assessment Questionnaire and Visual Analog Scale over 12 months in both trials. Participants in the ZAP trial received zoledronic acid prior to initiating letrozole and after 6 months; ELPh participants included in the analysis were taking letrozole but not bisphosphonates. We analyzed patient-reported outcomes (PROs) and bone density in the ZAP trial using mixed-effects linear regression models and paired t tests, respectively.

RESULTS

From 2011 to 2013, 59 postmenopausal women enrolled in ZAP trial. All 59 (100%) women received baseline and 52 (88%) received 6-month zoledronic acid, and had similar characteristics to historical controls from the ELPh trial (n = 206). Cumulatively during the first year of AI, 37 and 67% of ZAP and ELPh participants reported AIMSS (p < 0.001), respectively. Within the ZAP trial, we did not observe significant changes in other PROs; however, we report improvements in bone mineral density.

CONCLUSIONS

Compared to historical controls, zoledronic acid administered concomitantly with adjuvant AIs was associated with a reduced incidence of AIMSS. A randomized controlled trial is required to confirm these findings.

Self-reported knee pain and disability among healthy individuals: reference data and factors associated with the Knee injury and Osteoarthritis Outcome Score (KOOS) and KOOS-Child

OBJECTIVE

To develop normative reference data for the Knee injury and Osteoarthritis Outcome Score (KOOS) and KOOS-Child, as well as investigate socio-demographic, psychological and physical factors associated with knee pain and disability among healthy adults.

METHOD

The KOOS or KOOS-Child (each containing five subscales) was administered to participants aged 8-101 years within the 1000 Norms Project, an observational study of 1000 self-reported healthy individuals. Self-efficacy, physical activity, body mass index (BMI), lower limb alignment, knee frontal plane projection angle (FPPA), knee range of motion (ROM), knee and hip strength, six-minute walk, 30-second chair stand and timed up and down stairs tests were collected. KOOS data were dichotomised using established cut-off scores and logistic regression analyses were conducted for each subscale.

RESULTS

Socio-demographic characteristics were similar to the Australian population. Normative reference data were generated for children (8-17 years) and adults (18-101 years). Female adults were up to twice as likely to report knee pain, symptoms and sport/recreation (Sport/Rec) limitations compared to males (P < .05). Older age, lower self-efficacy, greater BMI, varus lower limb alignment, lower knee flexion ROM and lower hip external rotation (ER) strength were independently associated with knee pain and disability among adults.

CONCLUSIONS

Age- and gender-stratified reference data for the KOOS and KOOS-Child have been developed to guide interpretation of results in practice and research for individuals with knee disorders. Psychological and physical factors are linked with self-reported knee pain/disability among adults, and longitudinal studies to investigate causation are required.

Child passenger safety for inner-city Latinos: new approaches from the community

OBJECTIVE

Motor vehicle crashes injuries, the leading cause of death for Latino children in the United States, can be reduced by the correct use of child safety seats. This study evaluated the ability of a community health worker education program to improve proper child safety seat usage in urban low income Latino families.

METHODS

At a series of check events, proper child safety seat usage in families who had received an education intervention was compared with similar families who had not. The education intervention, provided by Latino community health workers trained as child passenger safety technicians, used videos and an office demonstrator. Members of the target community initiated the study and participated in its subsequent design and implementation.

RESULTS

The families that participated in the study were primarily Mexican with low income, education, and acculturation levels. Forty six rear facing and 44 forward facing child safety seats were checked. Families exposed to the intervention were more likely to have their child's seat within the manufacturer's recommended weight/height range, their child facing the correct direction, the harness straps positioned properly, to have not been in a crash, the harness straps snug, the harness retainer clip used correctly, the seat belt routed correctly, and the seat belt locked.

CONCLUSIONS

Exposure to an educational intervention provided by community health workers trained as child passenger safety technicians was associated with child safety seats being used more properly than seats of families not exposed to the intervention in an urban low income Latino community.

The effect of repeated exposure to particulate air pollution (PM10) on the bone marrow

Studies have shown that exposure to ambient particulate matter is related to an increased cardiopulmonary morbidity and mortality. The present study was designed to measure the effect of repeated exposure to urban air particles (PM10) on the rate of production and release of polymorphonuclear leukocytes (PMN) from the bone marrow into the peripheral blood. Rabbits exposed to PM10 (5 mg) twice a week for 3 wk, were given a bolus of 5'-bromo-2'-deoxyuridine (BrdU) to label dividing cells in the marrow that allows us to calculate the transit time of PMN in the bone marrow mitotic and postmitotic pools. The PM10 exposure (n = 8) causes a persistent increase in circulating band cells (p < 0.05) and a shortening of the transit time of PMN through the postmitotic pool in the marrow (64.4 +/- 2.2 h to 56.3 +/- 2.2 h, p < 0.05) if compared with vehicle-exposed control subjects (n = 6). PM10 exposure increases the bone marrow pool of PMN particularly the mitotic pool of PMN (p < 0.05). The PM10 were distributed diffusely in the lung and caused a mild mononuclear inflammation. The percentage of alveolar macrophages containing PM10 correlated significantly with the bone marrow PMN pool size (total pool r2 = 0.56, p < 0.012, mitotic pool r2 = 0.61, p < 0.007) and the transit time of PMN through the postmitotic pool (r2 = -0.42, p < 0.043). We conclude that repeated exposure to PM10 stimulates the bone marrow to increase the production of PMN in the marrow and accelerate the release of more immature PMN into the circulation. The magnitude of these changes was related to the amount of particles phagocytosed by alveolar macrophages.

Stability of red cell antigens and plasma coagulation factors stored in a non-diethylhexyl phthalate-plasticized container

Red cell antigen stability studies were performed to evaluate whether the storage of red cells in plastic segments made up of a new non-di-2(ethylhexyl)phthalate (DEHP)-plasticized material resulted in poststorage antigenic reactivity different from that seen in segments made from DEHP-containing plastic. Serial 1-in-2 dilutions of commercially available antisera were prepared and tested by using stored red cells obtained from segments on Days 0, 28, 42, and, in some instances, 49. Antigenic determinants tested included A, B, D, c, K, Le(a), Fya, Jka, M, and P1. To minimize variability, the same reagent lots were used throughout each study, and the same technologists performed the assays in each laboratory. No significant differences in titration scores were seen when cells stored in segments made of the test plastic were compared with cells obtained from the same donor and stored for the same length of time in segments made of control plastic. In addition, plasma coagulation factor stability was studied in fresh-frozen plasma and cryoprecipitate stored for up to 1 year in the non-DEHP-plasticized plastic containers. No significant differences were seen in prothrombin time, activated partial thromboplastin time, fibrinogen content, or factor V, VII, VIII, IX, or X activity as compared with plasma stored for equal periods of time in control plastic containers. It is concluded that the test plastic does not adversely affect red cell antigenic reactivity or plasma coagulation factor stability and that it is suitable for use in clinical transfusion practice.
