The effectiveness of care manager training in a multidisciplinary plan-do-check-adjust cycle on prevention of undesirable events among residents of geriatric care facilities.

AIM: Undesirable events, such as falls, aspiration, and pressure ulcers, are associated with functional decline and lower quality of life among older adults. This study describes the frequency of such events among residents of geriatric care facilities and assesses the effect of training care managers in a multidisciplinary plan-do-check-adjust cycle on preventing such events. METHODS: This was a Japan-based, non-randomized cluster intervention study. The intervention group comprised geriatric care facilities from which care managers had attended a training course, while the control group comprised facilities with care managers who did not receive this training. Six-month pre-admission and 3-month post-admission incidences of undesirable events were collected from both groups, and the two groups were compared. RESULTS: Valid data were collected from 862 residents (416 and 446 from the intervention and control groups, respectively) from 130 facilities (60 and 70, respectively). Three-month post-admission incidences were 27.8%, 20.0%, and 11.3% for falls, fever, and pressure ulcers, respectively. There was no difference between the groups regarding post-admission incidence for any event type. Training care managers reduced the post-admission incidence of pressure ulcers among residents with a history of such ulcers. CONCLUSIONS: The training of care managers in a multidisciplinary risk-management cycle was not effective for preventing falls, fever, or pressure ulcers. Results underscore the difficulty of preventing risk events in geriatric care facility residents even with organizational training efforts. The authors believe it is important to share such risks with residents and their families. Geriatr Gerontol Int 2021; 21: 842-848.

Association of care workers' job satisfaction and global happiness with change of functional performance of severely disabled elderly residents in nursing homes: a cohort and questionnaire study in Japan.

OBJECTIVES: There is growing concern regarding quality of work life (QWL) among care staff in nursing homes. However, little is known about the impact of QWL on nursing home residents' functional performance. Recent literature suggests that job satisfaction and happiness of healthcare workers reflect their perceived QWL and impact the quality of their care. This study examined the association between job satisfaction and global happiness with change in functional performance of severely disabled elderly residents in nursing homes. DESIGN: A retrospective cohort study of nursing home residents combined with a questionnaire survey of their care staff. SETTING: Eighteen nursing homes in Japan. PARTICIPANTS: Data were collected from 1000 residents with a required care level of 3-5 and from 412 care staff in nursing homes between October 2017 and March 2018. OUTCOMES AND EXPLANATORY VARIABLES: Functional performance was structurally assessed with ICF (International Classification of Functioning, Disability and Health) staging, composed of 52 items concerning activities of daily life, cognitive function and social participation, at baseline and 6 months later. Deterioration and improvement of functional performance were dichotomously defined as such change in any of the items. QWL of care staff was evaluated with a questionnaire including questions about job satisfaction and global happiness. RESULTS: Functional performance deteriorated and improved in 23.0% and 12.7% of residents, respectively. Global happiness of care staff was associated with lower probability of residents' deterioration (adjusted OR, 0.61; CI 0.44 to 0.84). There was no significant correlation between job satisfaction or happiness of care staff and improvement of residents' functional performance. CONCLUSION: These results suggest that QWL of care staff is associated with changes in functional performance of elderly people with severe disabilities in nursing homes.

Establishment of a serodiagnosis system for the detection of Toxocara spp. and Ascaris suum infection in chickens.

Chickens are considered to act as paratenic hosts for agents, Toxocara canis, T. cati and Ascaris suum; which cause ascarid larva migrans syndrome (ascarid LMS) in humans. In addition, they are the definitive host for Ascaridia galli, considered not to be infective for humans. All ascarid parasites can have a high homology of antigenicity, leading to cross-reactivity in serodiagnostic assays. This study was conducted to establish a procedure for the serological detection of those roundworm infections in chickens. Twenty-five male Julia chickens were divided into five groups (n = 5); T. canis-, T. cati-, Ascaris suum- and Ascaridia galli-infected, and an uninfected control group. In Ascaris suum-soluble worm antigen preparation (As-SWAP) ELISA, all infected groups showed an elevation of anti-ascarid antibodies, indicating the usefulness of As-SWAP as a screening antigen for the detection of ascarid infections. For infecting species identification, T. canis-excretory/secretory (Tc-ES) and Ascaris suum-ES (As-ES) antigen ELISA were conducted by serial dilution sera. Toxocara spp.-infected sera showed stronger binding to Tc-ES than As-ES, while Ascaris suum and Ascaridia galli-infected sera bound to As-ES more strongly than Tc-ES. To discriminate between Ascaris suum and Ascaridia galli infection, sera were pre-incubated with Ascaridia galli-SWAP antigen and applied to Tc-ES and As-ES ELISAs. In this pre-adsorbed ES antigen ELISAs, only the Ascaris suum infected group showed positive binding to As-ES, resulting from the adsorption of cross-reactive antibodies in Ascaridia galli-infected sera. Finally, anti-Toxocara specific antibodies were confirmed by Tc-ES western blot (WB). Toxocara spp.-infected sera showed toxocariasis-specific band pattern in Tc-ES WB, while no specific band appeared on any strip incubated with Ascaris suum, Ascaridia galli-infected and uninfected sera. In conclusion, the serodiagnostic assays evaluated in this study are useful for the detection of ascarid infections in chickens.
