Creating opportunities to improve detection of older adult abuse: a national interRAI study.

Despite being recognized as a major global health issue, older adult abuse (OAA) remains largely undetected and under-reported. Most OAA assessment tools fail to capture true prevalence. Follow up of patients where abuse exposure is not easily determined is a necessity. The interRAI-HC (International Resident Assessment Instrument-Home Care) currently underestimates the extent of abuse. We investigated how to improve detection of OAA using the interRAI-HC. Analysis of 7 years of interRAI-HC data from an Aotearoa New Zealand cohort was completed. We identified that through altering the criteria for suspicion of OAA, capture rates of at-risk individuals could be nearly doubled from 2.6% to 4.8%. We propose that via adapting the interRAI-HC criteria to include the "unable to determine" whether abuse occurred (UDA) category, identification of OAA sufferers could be substantially improved. Improved identification will facilitate enhanced protection of this vulnerable population.

Older adults abuse: analysis of a New Zealand national dataset.

Older adult abuse (OAA), defined as abuse, neglect, or mistreatment of persons aged 65 years or older, is a globally pervasive concern, with severe consequences for its victims. While internationally reported rates of OAA are in the range of 5-20% per annum, New Zealand lacks the necessary data to quantify the issue. However, with a growing aging population, an increase in the prevalence of OAA is predicted. We investigated the extent of OAA in New Zealand, utilizing the mandatory interRAI-HC (International Resident Assessment Instrument-home care assessment) dataset, which included 18,884 interviewees from the Southern District Health Board between 2013 and 2019. Findings confirmed our hypothesis that the interRAI assessment is neither sufficiently sensitive nor specific capturing only 3% from a population of increased frailty and thus at higher risk of abuse. We characterized OAA victims as relatively younger males, depressed, and with impaired decision-making capacity. If the interRAIs were to serve as a preliminary screening tool for OAA in New Zealand, it would be germane to implement changes to improve its detection rate. Further studies are urgently called for to test changes in the interRAI that will aid in identifying often missed cases of OAA better and thus offer protection to this vulnerable population.

Assessing need for primary care services: analysis of New Zealand Health Survey data.

Introduction The 2001 Primary Health Care Strategy provided significant new government funding for primary care (general practice and related services) via capitation funding formulas. However, there remain important unanswered questions about how capitation funding formulas should be redesigned to ensure equitable and sustainable service provision to all population groups. Aim To compare levels of chronic illness, utilisation, and unmet need in patients categorised as 'high-need' with those categorised as non-'high-need' using the definitions that are used in the current funding context, in order to inform primary care funding formula design. Methods Respondents of the New Zealand Health Survey (2018-19) were categorised into 'high-need' and non-'high-need', as defined in current funding formulas. We analysed: (i) presence, and number, of chronic diseases; (ii) self-reported primary care utilisation (previous 12 months); and (iii) self-reported unmet need for primary care (previous 12 months). Analyses used integrated survey weights to account for survey design. Results In total, 29% of respondents were 'high-need', of whom 50.2% reported one or more chronic conditions (vs 47.8% of non-'high-need' respondents). 'High-need' respondents were more likely than non-'high-need' respondents to: report three or more chronic conditions (14.4% vs 13.7%); visit a general practitioner more often (seven or more visits per year: 9.9% vs 6.6%); and report barriers to care. Discussion There is an urgent need for further quantification of the funding requirements of general practices serving high proportions of 'high-need' patients in order to ensure their viability, sustainability and the provision of quality of care.
