Lonely in a crowd: loneliness in New Zealand retirement village residents.

OBJECTIVES: The number of older people choosing to relocate to retirement villages (RVs) is increasing rapidly. This choice is often a way to decrease social isolation while still living independently. Loneliness is a significant health issue and contributes to overall frailty, yet RV resident loneliness is poorly understood. Our aim is to describe the prevalence of loneliness and associated factors in a New Zealand RV population. DESIGN: A resident survey was used to collect demographics, social engagement, loneliness, and function, as well as a comprehensive geriatric assessment (international Resident Assessment Instrument [interRAI]) as part of the "Older People in Retirement Villages Study." SETTING: RVs, Auckland, New Zealand. PARTICIPANTS: Participants included RV residents living in 33 RVs (n = 578). MEASUREMENTS: Two types of recruitment: randomly sampled cohort (n = 217) and volunteer sample (n = 361). Independently associated factors for loneliness were determined through multiple logistic regression with odds ratios (ORs). RESULTS: Of the participants, 420 (72.7%) were female, 353 (61.1%) lived alone, with the mean age of 81.3 years. InterRAI assessment loneliness (yes/no question) was 25.8% (n = 149), and the resident survey found that 37.4% (n = 216) feel lonely sometimes/often/always. Factors independently associated with interRAI loneliness included being widowed (adjusted OR 8.27; 95% confidence interval [CI] 4.15-16.48), being divorced/separated/never married (OR 4.76; 95% CI 2.15-10.54), poor/fair quality of life (OR 3.37; 95% CI 1.43-7.94), moving to an RV to gain more social connections (OR 1.55; 95% CI 0.99-2.43), and depression risk (medium risk: OR 2.58, 95% CI 1.53-4.35; high risk: OR 4.20, 95% CI 1.47-11.95). CONCLUSION: A considerable proportion of older people living in RVs reported feelings of loneliness, particularly those who were without partners, at risk of depression and decreased quality of life and those who had moved into RVs to increase social connections. Early identification of factors for loneliness in RV residents could support interventions to improve quality of life and positively impact RV resident health and well-being.

Convergent Validity, Concurrent Validity, and Diagnostic Accuracy of the interRAI Depression Rating Scale.

AIMS: Depression Rating Scale (DRS) is one of the clinical outcome measures of the International Resident Assessment Instrument (interRAI) assessment. The primary aim of this study is to investigate the diagnostic accuracy and concurrent validity of the 3-day assessment window version of the DRS. METHODS: The performance of DRS was compared with a gold standard clinical diagnosis of depression in 92 patients (age ≥65) who had interRAI version 9.1 Home Care assessment completed within 30 days of discharge from psychogeriatric inpatient care or memory clinic assessment. RESULTS: The DRS had poor diagnostic accuracy for depression diagnosis with an area under the curve of 0.68 (95% confidence interval [CI] = 0.57-0.77). The DRS score had a poor to moderate correlation with the Health of the Nation Outcome Scale 65+ depression item score ( rs = 0.30, 95% CI = 0.09-0.48, P = .006). CONCLUSION: This study and the existing literature raise concerns that the DRS is not an adequate measure of depression.

Routine surveillance ultrasound for the management of central venous catheters in neonates.

OBJECTIVES: To evaluate the frequency of central venous catheter (CVC)-related thrombi detected by routine surveillance ultrasound, and to assess whether positive findings had an impact on management or outcomes. STUDY DESIGN: All neonates in a tertiary neonatal intensive care unit who had a CVC inserted for >14 days underwent routine surveillance ultrasound biweekly between January 2003 and December 2009. Data were reviewed retrospectively. RESULTS: Although all neonates were asymptomatic at time of surveillance ultrasound, 645 of the total 1333 CVCs inserted in 1012 neonates underwent surveillance ultrasound, and thrombi were detected in 69 (10.7%). The CVCs with thrombi were more likely to be removed for nonelective reasons compared with CVCs without thrombi (59% vs 38%; P = .001; OR, 2.4, 95% CI 1.4-3.9). A total of 955 surveillance ultrasounds were performed to detect and monitor 69 CVCs with thrombi. The majority of thrombi were nonocclusive and nonprogressive. A change in management occurred in 8 cases of CVC-related thrombi (12%), or 1% of all screened cases. An average of 14 ultrasounds were required to detect and monitor 1 CVC with thrombus, at a cost of $951 per CVC with thrombus and $8106 per case of CVC-related thrombi with a change in treatment. CONCLUSION: Asymptomatic thrombi were detected in a significant proportion of CVCs by routine surveillance ultrasound. There were significant costs, but infrequent changes to patient management.

Changes in hospitalisation rates in older people before and after moving to a retirement village.

OBJECTIVES: An increasing proportion of older people live in Retirement Villages ('villages'). This population cites support for health-care issues as one reason for relocation to villages. Here, we examine whether relocation to villages is associated with a decline in hospitalisations. METHODS: Retrospective, before-and-after observational study. SETTING: Retirement villages, Auckland, New Zealand. PARTICIPANTS: 466 cognitively intact village residents (336 [72%] female); mean (SD) age at moving to village was 73.9 (7.7) years. Segmented linear regression analysis of an interrupted time-series design was used. MAIN OUTCOME MEASURES: all hospitalisations for 18 months pre- and postrelocation to village. SECONDARY OUTCOME: acute hospitalisations during the same time periods. RESULTS: The average hospitalisation rate (per 100 person-years) was 44.9 (95% confidence interval [CI] = 36.3-55.6) 18-10 months before village relocation, 58.9 (95% CI = 48.3-72.0) 9-1 months before moving, 47.9 (95% CI = 38.8-59.1) 1-9 months after moving and 62.4 (95% CI = 51.2-76.0) 10-18 months after moving. Monthly average hospitalisation rate (per 100 person-years) increased before relocation to village by an average of 1.2 (95% CI = 0.01-1.57, p = .04) per month from 18 to 1 month before moving, and there was a change in the level of the monthly average hospitalisation rate immediately after relocation (mean difference [MD] = -18.4 per 100 person-years, 95% CI = -32.8 to -4.1, p = .02). The trend change after village relocation did not differ significantly from that before moving. CONCLUSIONS: Although we cannot reliably claim causality, relocation to a retirement village is, for older people, associated with a significant but non-sustained reduction in hospitalisation.

Bar-code verification: reducing but not eliminating medication errors.

Using observation, eye tracking, and clinical simulation with embedded errors, we studied the impact of bar-code verification on error identification and recovery during medication administration. Data supported that bar-code verification may reduce but does not eliminate patient identification (ID) and medication errors during clinical simulation of medication administration.

The prevalence and intensity of pain in older people living in retirement villages in Auckland, New Zealand.

Chronic pain is common in older people. However, little is known about how pain is experienced in residents of retirement villages ('villages'), and how pain intensity and associations are experienced in relation to characteristics of residents and village living. We thus aimed to examine pain levels, prevalence and associated factors in village residents. The current paper is a cross-sectional analysis of baseline data from the 'Older People in Retirement Villages' study in Auckland, New Zealand. Between July 2016 and August 2018, 578 village residents were interviewed face-to-face by gerontology nurse specialists, using interRAI Community Health Assessment (CHA) and customised survey. We used a validated pain scale and multivariable logistic regression analyses adjusted for pre-specified confounders. Residents' median age was 82 years; 420 (73%) were female; 270 (47%) exhibited/reported daily pain, and in 11% this was severe. After controlling for confounders, daily pain was positively associated with self-reported arthritis (OR = 3.88, 95% CI = 2.57-5.87), poor/fair self-reported health (OR = 3.19, 95% CI = 1.29-7.93), having no health clinic on-site (OR = 1.76, 95% CI = 1.10-2.83), and minimal fatigue (diminished energy but completes normal day-to-day activities) (OR = 1.77, 95% CI = 1.11-2.81). Similar associations were observed for levels of pain. We conclude that levels of pain and prevalence of daily pain are high in village residents. Self-reported arthritis, self-reported poor/fair health, no health clinic on-site and minimal fatigue are all independently associated with a higher risk of daily pain and with levels of pain. This study suggests potential opportunities for villages to better provide on-site support to decrease prevalence and severity of pain for their residents, and thus potentially increase wellbeing and quality-of-life, though as we cannot prove causality, more research is needed.

Learning from a multidisciplinary randomized controlled intervention in retirement village residents.

BACKGROUND: Retirement villages (RVs), also known as continuing care retirement communities, are an increasingly popular housing choice for older adults. The RV population has significant health needs, possibly representing a group with needs in between community-dwelling older adults and those in long-term residential care (LTC). Our previous work shows Gerontology Nurse Specialist (GNS)-facilitated multidisciplinary team (MDT) interventions may reduce hospitalizations from LTC. This study tested whether a similar intervention reduced hospitalizations in RV residents. METHODS: Open-label randomized controlled trial in which 412 older residents of 33 RVs were randomized (1:1) to an MDT intervention or usual care. SETTING: RVs across two District Health Boards in Auckland, New Zealand. Residents were eligible if considered high risk of health/functional decline (triggering ≥3 interRAI Clinical Assessment Protocols or needing special consideration identified by GNS). INTERVENTION: GNS-facilitated MDT intervention, including geriatrician/nurse practitioner and clinical pharmacist, versus usual care. Primary outcome was time from randomization to first acute hospitalization. Secondary outcomes were rate of acute hospitalizations, LTC admission, and mortality. Twelve residents died before randomization; all others (n = 400: MDT intervention = 199; usual care = 201) were included in intention-to-treat analyses. RESULTS: Mean (SD) age was 82.2 (6.9) years, 302 (75.5%) were women, and 378 (94.5%) were European. Over median 1.5 years follow-up, no difference was found in hazard of acute hospitalization between the MDT intervention (51.8%) and usual care (49.3%) groups (Hazard ratio [HR] = 1.01, 95% CI = 0.77-1.34). No difference was found in the incidence rate of acute hospitalizations between the MDT intervention (0.69 per person-year) and usual care (0.86 per person-year) groups (incidence rate ratio = 0.81, 95% CI = 0.59-1.10). Similar results were seen for the proportion of residents with LTC transition (HR = 1.18, 95% CI = 0.65-2.11) and mortality (HR = 0.70, 95% CI = 0.36-1.35). CONCLUSION: Further studies are needed to assess the effects of other patient-centered interventions and outcomes with adequate primary care integration.

Factors associated with healthcare utilization and trajectories in retirement village residents.

BACKGROUND: To study healthcare utilization and trajectories, and associated factors, in older adults in retirement villages (RVs), also known as continuing care retirement communities. METHODS: Prospective cohort study of 578 cognitively intact residents from 34 RVs in Auckland, New Zealand (NZ). MEASUREMENT: InterRAI-Community Health Assessment (includes core items that may trigger functional supplement (FS) completion in those with higher needs, and generates clinical assessment protocols (CAPs) in those with potential unmet needs). OUTCOMES: time to acute hospitalization, long-term care (LTC), and death during average 2.5 years follow-up. RESULTS: Three hundred seven (53%) residents had acute hospitalizations, 65 (11%) moved to LTC, and 51 (9%) died over a mean of 2.5 years. Factors associated with increased risk of acute hospitalization included CAP-falls (high risk) triggered, number of comorbidities, not having left RV in 2 weeks prior, moderate/severe hearing impairment, CAP-cardiorespiratory conditions triggered, acute hospitalization in year prior and age, with significant hazard ratios (HR) ranging between 1.03 and 2.90. Factors associated with reduced risk of hospitalization included other (non-NZ) European ethnicity (HR 0.73, 95% CI 0.55-0.98, p = 0.04), presence of on-site clinic (HR 0.62, 95% CI 0.45-0.85, p = 0.003), no influenza vaccination (HR 0.56, 95% CI 0.38-0.83, p = 0.004). Factors associated with LTC transition included FS triggered (HR 3.84, 95% CI 1.92-7.66, p < 0.001), CAP-instrumental activities of daily living (IADL) (HR 2.62, 95% CI 1.22-5.62, p = 0.01), CAP-social relationship triggered (HR 2.00, 95% CI 1.13-3.55, p = 0.02), and age (HR 1.13, 95% CI 1.07-1.18 p < 0.001). Factors associated with mortality included number of comorbidities (HR 3.75, 95% CI 1.54-9.10, p = 0.004 for 3-5 comorbidities), CAP-IADL triggered (HR 3.05, 95% CI 1.30-7.16, p = 0.01), and age (HR 1.11, 95% CI 1.05-1.18, p < 0.001). CONCLUSION: A large proportion of cognitively intact RV residents are admitted to hospital in mean 2.5 years of follow-up. Multiple factors were associated with acute hospitalization risk. On-site clinics were associated with reduced risk and should be considered in RV development.

Research in the retirement village community-The problems of recruiting a representative cohort of residents in Auckland, New Zealand.

OBJECTIVES: Retirement villages are semi-closed communities, access usually being gained via village managers. This paper explores issues recruiting a representative resident cohort, as background to a study of residents, to acquire sociodemographic, health and disability data and trial an intervention designed to improve outcomes. METHODS: We planned approaching all Auckland/Waitemata District villages and, via managers, contacting residents ('letter-drop'; 'door-knocks'). In 'small' villages (n ≤ 60 units), we planned contacting all residents, randomly selecting in 'larger' villages. We excluded those with doubtful or absent legal capacity. RESULTS: We approached managers of 53 of 65 villages. Thirty-four permitted recruitment. Some prohibited 'letter-drops' and/or 'door-knocks'. Hence, we recruited volunteers (23 villages) via meetings, posters, newsletters and word-of-mouth, that is representative sampling obtained from 11/34 villages. We recruited 578 residents (median age = 82 years; 420 = female; 217:361 sampled:volunteers), finding differences in baseline parameters of sampled vs. volunteers. CONCLUSION: Due to organisational/managers' policy, and national legislation restrictions, our sample does not represent our intended population well. Researchers should investigate alternative data sources, for example electoral rolls and censuses.

Health profile of residents of retirement villages in Auckland, New Zealand: findings from a cross-sectional survey with health assessment.

OBJECTIVES: Retirement villages (RV) have expanded rapidly, now housing perhaps one in eight people aged 75+ years in New Zealand. Health service initiatives might better support residents and offer cost advantages, but little is known of resident demographics, health status or needs. This study describes village residents-their demographics, socio-behavioural and health status-noting differences between participants who volunteered and those who were sampled. DESIGN: Cross-sectional study of village residents. The cohort formed will also be used for a longitudinal study and a randomised controlled trial. Village managers (sometimes after consulting residents) decided if representative sampling could be undertaken in each village. Where sampling was not approved, volunteers were sought. SETTING: 33 RV were included from a total of 65 villages in Auckland, New Zealand. PARTICIPANTS: Residents (n=578) were recruited either by sampling (n=217) or as volunteers (n=361) during 2016-2018. Each completed a survey and an International Resident Assessment Instrument (interRAI) health needs assessment with a gerontology nurse specialist. RESULTS: Median age of residents was 82 years, 158 (27%) were men; 61% lived alone. Downsizing (77%), less stress (63%) and access to healthcare assistance (61%) were most common reasons for entry. During the 2 weeks prior to survey, 34% received home supports and 10% personal care. Hypertension, heart disease, arthritis and pain were reported by over 40%. Most common unmet needs related to managing cardiorespiratory symptoms (50%) and pain (48%). Volunteers and sampled residents differed significantly, mainly in socio-behavioural respects. CONCLUSIONS: Common conditions including hypertension, arthritis and atrial fibrillation, are recorded in interRAI as text, and thus overlooked in interRAI reports. Levels of unmet need indicate opportunities to improve health services to better manage chronic conditions. Healthcare service providers and village operators could cooperate to design and test service initiatives that better meet residents' needs and offer cost benefits.

Routine surveillance for bloodstream infections in a pediatric hematopoietic stem cell transplant cohort: Do patients benefit?

BACKGROUND: Hematopoietic stem cell transplant (HSCT) recipients are at a high risk for late bloodstream infection (BSI). Controversy exists regarding the benefit of surveillance blood cultures in this immunosuppressed population. Despite the common use of this practice, the practical value is not well established in non-neutropenic children following HSCT. METHODS: At the IWK Health Centre (Halifax, Nova Scotia), weekly surveillance blood cultures from central lines are drawn from children following HSCT until the line is removed. A retrospective chart review was performed to determine the utility and cost of this practice. Eligible participants were non-neutropenic HSCT recipients with central venous access lines. The cost of laboratory investigations, nursing time, hospital stay and interventions for positive surveillance cultures was calculated. RESULTS: Forty-three HSCTs were performed in 41 children. Donors were allogenic in 33 cases (77%) and autologous in 10 cases (23%). There were 316 patient contacts for surveillance cultures (mean seven per patient) and 577 central line lumens sampled. Three of 43 patients (7%) had clinically significant positive surveillance blood cultures. Bacteria isolated were Klebsiella pneumoniae (n=2) and Corynebacterium jeikeium (n=1). All follow-up cultures before initiation of antimicrobial therapy were sterile. All three patients were admitted for antimicrobial therapy if they were not already hospitalized and/or had an uncomplicated course. The estimated total cost of BSI surveillance and management of asymptomatic infection over six years was $27,989. CONCLUSION: The present study suggests that BSI surveillance in children following HSCT engraftment has a very low yield and significant cost. It is unclear whether it contributes to improved patient outcomes.

Full-time or part-time work in nursing: preferences, tradeoffs and choices.

Nursing human resources are limited; thus, effective deployment of personnel is essential to optimize staff capacity. The nursing profession competes for staff in environments where human capital is at a premium. To maximize recruitment and retention, it is imperative that nurses' work preferences be taken into account.

The Combined Impact of Surgical Team Education and Chlorhexidine 2% Alcohol on the Reduction of Surgical Site Infection following Cardiac Surgery.

BACKGROUND: The use of 2% chlorhexidine in 70% alcohol (CHG) has been associated with reduction in catheter-related bloodstream infections and surgical site infection (SSI) in general surgery. Also, improved awareness of best practice from the perspective of the operative team is likely to result in reductions in SSI rates. METHODS: This is an ambispective cohort study of patients undergoing elective cardiac surgery. Between January 2010 and December 2010, patients underwent surgical preparation using Alcohol Povidone Iodine (API). Between January 2011 and December 2011, the surgical team received education and switched to CHG for surgical preparation. Univariate analysis was performed to identify the impact of known risk factors for SSI. A logistic regression model was then fit to estimate the effect of education and CHG in the reduction of SSI in 2011, controlling for known SSI risk factors. RESULTS: There was a substantial reduction in overall SSI rate in 2011 following staff education and the introduction of CHG. The overall unadjusted SSI rate was 4.67% versus 2.08% (p<0.05) for 2010 and 2011 respectively. Using a logistic regression model, the combined effect of education and CHG in 2011 was a 63% reduction in SSI in cardiothoracic surgery (OR 0.37, 95% CI: 0.17-0.83, p=0.016), controlling for age, major co-morbidities, and SSI risk factors. CONCLUSIONS: Using CHG as pre-operative antiseptic in cardiothoracic surgery in a risk-adjusted cohort with education of the surgical team is associated with significantly lower SSI infection rates when compared with API. Emphasis must be placed on the multifactorial approach required to prevent postoperative wound infections.
