Factors Associated With COVID-19 Hospitalizations and Deaths in French Nursing Homes

ObjectivesTo describe the clinical characteristics and management of residents in French nursing homes with suspected or confirmed coronavirus disease 2019 (COVID-19) and to determine the risk factors for COVID-19–related hospitalization and death in this population.DesignA retrospective multicenter cohort study.Setting and ParticipantsFour hundred eighty nursing home residents with suspected or confirmed COVID-19 between March 1 and May 20, 2020, were enrolled and followed until June 2, 2020, in 15 nursing homes in Marseille’s greater metropolitan area.MethodsDemographic, clinical, laboratory, treatment type, and clinical outcome data were collected from patients’ medical records. Multivariable analysis was used to determine factors associated with COVID-19–related hospitalization and death. For the former, the competing risk analysis—based on Fine and Gray’s model—took death into account.ResultsA total of 480 residents were included. Median age was 88 years (IQR 80-93), and 330 residents were women. A total of 371 residents were symptomatic (77.3%), the most common symptoms being asthenia (47.9%), fever or hypothermia (48.1%), and dyspnea (35.6%). One hundred twenty-three patients (25.6%) were hospitalized and 96 (20%) died. Male gender [specific hazard ratio (sHR) 1.63, 95% confidence interval (CI) 1.12-2.35], diabetes (sHR 1.69, 95% CI 1.15-2.50), an altered level of consciousness (sHR 2.36, 95% CI 1.40-3.98), and dyspnea (sHR 1.69, 95% CI 1.09-2.62) were all associated with a greater risk of COVID-19–related hospitalization. Male gender [odds ratio (OR) 6.63, 95% CI 1.04-42.39], thermal dysregulation (OR 2.64, 95% CI 1.60-4.38), falls (2.21 95% CI 1.02-4.75), and being aged >85 years (OR 2.36, 95% CI 1.32-4.24) were all associated with increased COVID-19–related mortality risk, whereas polymedication (OR 0.46, 95% CI 0.27-0.77) and preventive anticoagulation (OR 0.46, 95% CI 0.27-0.79) were protective prognostic factors.Conclusions and ImplicationsMale gender, being aged >85 years old, diabetes, dyspnea, thermal dysregulation, an altered level of consciousness, and falls must all be considered when identifying and protecting nursing home residents who are at greatest risk of COVID-19–related hospitalization and death.     

Effect of Multiple Previous Miscarriages on Health Behaviors and Health Care Utilization During Subsequent Pregnancy

BackgroundWomen with a history of miscarriage report feeling emotionally guarded during a subsequent pregnancy and may be at increased risk for pregnancy-related anxiety and greater health care utilization compared with women without a history of miscarriage. However, these behaviors have not been studied in women with a history of multiple miscarriages.MethodsWe examined the effect of a history of multiple miscarriages on health behaviors and health care utilization in 2,854 women ages 18 to 36 years expecting their first live-born baby. Self-reported health behaviors and use of health care resources during pregnancy were compared for women with a history of two or more miscarriages and women with one or no miscarriages.FindingsWomen with a history of multiple miscarriages were more than four times as likely to smoke during pregnancy (adjusted odds ratio [aOR], 4.69; 95% CI, 2.63–8.38) compared with women without a history of multiple miscarriages. They initiated prenatal care earlier (7.0 vs. 8.2 weeks gestation), had higher odds of third trimester emergency department visit (aOR, 2.21; 95% CI, 1.24–3.94), higher odds of hospitalization during pregnancy (aOR, 1.66; 95% CI, 1.01–2.73), and twice the mean number of third trimester emergency department visits and hospitalizations during pregnancy.ConclusionsWomen with a history of multiple miscarriages may be more likely to smoke and may demonstrate increased health care utilization during a subsequent pregnancy. Compassionate, individualized, and supportive counseling by providers may address smoking and other health behaviors as well as increased health care utilization.     

Reducing the Risk of Hospitalization for Nursing Home Residents: Effects and Facility Variation From OPTIMISTIC

ObjectivesThe Optimizing Patient Transfers, Impacting Medical Quality, and Improving Symptoms: Transforming Institutional Care (OPTIMISTIC) project led to significant decreases in potentially avoidable hospitalizations of long-stay nursing facility residents in external evaluation. The purpose of this study was to quantify hospitalization risk from the start of the project and describe the heterogeneity of the enrolled facilities in order to better understand the context for successful implementation.DesignPre-post analysis design of a prospective intervention within a single group.Setting and ParticipantsA total of 4320 residents in the 19 facilities were included from admission until time to the first hospitalization.MeasuresData were extracted from Minimum Data Set assessments and linked with facility-level covariates from the LTCFocus.org data set. Kaplan-Meier and Cox proportional hazards regression were used to assess risk of hospitalization during the preintervention period (2011-2012), a “ramp-up” period (2013-2014), and an intervention period (2015-2016).ResultsThe cohort consisted of 4230 long-stay nursing facility residents. Compared with the preintervention period, residents during the intervention period had an increased probability of having no hospitalizations within 1 year, increasing from 0.51 to 0.57, which was statistically significant (P < .001). In adjusted Cox models, the risk of hospitalization was lower in the ramp-up period compared to the pre-period [hazard ratio (HR) 0.85, 95% confidence interval (CI) 0.75-0.95] and decreased further during the intervention period (HR 0.74, 95% CI 0.65-0.84).Conclusions and ImplicationsAs part of a large multisite demonstration project, OPTIMISTIC has successfully reduced hospitalizations. However, this study highlights the magnitude and extent to which results differ across facilities. Implementing the OPTIMISTIC program was associated with a 16% risk reduction after the first 18 months and continued to a final risk reduction of 26% after 5½ years. Although this model of care reduces hospitalizations overall, facility variation should be expected.     

Effects of rotavirus vaccine on all-cause acute gastroenteritis and rotavirus hospitalizations in Israel: A nationwide analysis

BackgroundIn December 2010, the pentavalent rotavirus vaccine (RotaTeq) was added to the national immunization program in Israel. The study aim was to examine national reductions in all-cause acute gastroenteritis (AGE) and rotavirus gastroenteritis (RVGE) hospitalizations among children aged 0–59 months following the introduction of universal rotavirus immunization in Israel.MethodsWe extracted data from the Israel National Hospital Discharge Database. Hospitalization rates were calculated by dividing the annual number of all-cause AGE and RVGE hospitalizations by the number of children aged 0–59 months residing Israel. To assess rate reductions, we compared the mean hospitalization rate for the pre-vaccine years (2002–2008) with that for the universal vaccination years (2011–2017). Interrupted time-series analyses were undertaken. During 2008–2010 rotavirus vaccines were partially available.ResultsA total of 131,116 AGE hospitalizations were reported, of which 13,111 (10.0%) were coded as RVGE hospitalizations. The average annual all-cause AGE hospitalization rate during the pre-vaccine period was 147.9 (95% CI 146.7–149.0) per 10,000 children aged 0–59 months, and declined by 38.7–53.0% during the universal vaccination years. The average annual pre-vaccine RVGE hospitalization rate was 16.9 (95% CI 16.5–17.3) per 10,000 children, and declined by 89.1% during 2016–2017.Findings from interrupted time-series analyses showed significant impact of introducing universal rotavirus immunization on the declines of all-cause AGE and RVGE hospitalizations rates. A multivariable Autoregressive Integrated Moving Average model showed that the variable “immunization period” was a significant predictor of RVGE hospitalizations (t = 7.3, p < 0.001) for the universal vaccination years.The declines in hospitalizations rates of all-cause AGE were lower among Arab children compared to Jewish children, but the declines in RVGE rates were similar between the groups.ConclusionsNational hospitalization data demonstrated substantial and consistent reductions in all-cause AGE and RVGE hospitalizations following the implementation of universal rotavirus vaccination program.     

Acute gastroenteritis hospitalizations after implementation of universal mass vaccination against rotavirus

BackgroundEstonia implemented rotavirus universal mass vaccination (RV UMV) in July 2014. We aimed to describe changes in acute gastroenteritis (AGE) hospitalization during RV seasons before (2007–2013) and after (2015–2018) RV UMV and compare patient profile of hospitalized AGE patients aged 0–18 years during first two consecutive RV seasons 2015 vs 2016.MethodsWe described AGE hospitalization patterns pre-and post-vaccine era using Estonian Health Insurance Fund (HIF) database. During a two-year observational multicenter study in seven Estonian hospitals from 01st of February 2015 to 30th August 2016 we assessed patient profile of all patients who met pre-determined AGE criteria.ResultsIn post-vaccine era AGE hospitalization rate decreased from 10 to 8 per 1000 population (RR 0.81, 95% CI 0.79–0.83) compared to pre-vaccine era. Decreased RV seasonal activity, 81% (95% CI 77–84) and 55% (95% CI 52–58) reduction of rotavirus gastroenteritis (RVGE) hospitalization among age groups <1 and 1–4, respectively and upsurge of norovirus gastroenteritis (NoVGE) hospitalizations (RR = 1.8; 95% CI 1.6–1.9) was seen.In the multicenter observational study, among 2249 AGE patients hospitalized median age of RVGE patients increased from 2 to 3 years (p < 0.01) and duration of hospital stay decreased among RVGE, NoVGE and other GE patients during two consecutive RV seasons. According to Vesikari Clinical Severity Scoring System statistically significant change of severity score distribution in two RV seasons was seen (p < 0.001) with trend towards less severe AGE hospitalizations; 82.5% vs 70.5% severe cases in 2015 vs 2016, respectively.ConclusionRV UMV lead to immediate and sustainable reduction of hospitalizations due to RVGE in children aged <4 years and reduction of overall AGE accompanied with the decrease in the severity of hospitalized children.     

Web-Based Delirium Prevention Application for Long-Term Care Facilities

ObjectiveA web-based application was developed for medical staff to easily access and use a comprehensive delirium prevention management program—comprising risk prediction, assessment, and intervention—even in long-term care facilities with insufficient systems.DesignA randomized control trial.Setting and ParticipantsA long-term care facility with 250 beds in Korea. Participants were 130 facility residents aged 18 or older who understood the purpose of this study and for whom a legal representative provided participation consent. Participants were randomly assigned to the intervention and control groups (n = 65 per group).MethodsThe participants’ risk of delirium episodes was predicted using the web-based application Web_DeliPREVENT_4LCF. Delirium was assessed using the built-in Short Confusion Assessment Method (S-CAM). Among the intervention group, nonpharmacological, multicomponent delirium prevention interventions guided by the application were applied to participants who were predicted to be at risk for delirium or tested positive for delirium. The intervention was provided for 30 days.ResultsThe intervention group had a 0.30 times lower incidence of delirium [95% confidence interval (CI) 0.12–0.79; P = .015] and 0.08 times lower 1-month hospitalization mortality (95% CI 0.01–0.79; P = .031) than the control group. There were no differences between the 2 groups in delirium severity, mortality, and 3-month hospitalization mortality, long-term care facility discharge, and length of stay.Conclusions and ImplicationsThe Web_DeliPREVENT_4LCF was effective in reducing delirium episodes and 1-month in-hospital mortality. Therefore, even in Korean long-term care facilities, which lack manpower and electronic medical record systems compared with general hospitals, the health care professional can easily access and use the app for early detection and preventive intervention for residents’ delirium.RegistrationKCT0005804.     

Frailty Predicts Increased Health Care Utilization Among Community-Dwelling Older Adults: A Longitudinal Study in China

ObjectivesFrailty, a multidimensional syndrome characterized by vulnerability to stressors, is an emerging public health priority with high prevalence in older adults. Frailty has been identified to predictive negative health outcomes, yet quantified evidence regarding its effect on health care systems is scarce. This study examines how frailty affects health care utilization, and explores whether these associations varied by gender.DesignCohort study with a 2-year follow-up.Settingand Participants: Data were derived from 2 waves (2011 and 2013) of the China Health and Retirement Longitudinal Study, and 3119 community-dwelling participants aged ≥60 years were analyzed.MethodsFrailty was assessed by a validated frailty phenotype scale, and measures for health care utilization were self-reported. Panel data approach of mixed-effects regression models was used to examine the associations.ResultsLongitudinal results demonstrated that compared with robustness, prefrailty and frailty were both significantly associated with increased likelihood of outpatient visit, inpatient visit, and inpatient length of stay, even after adjusting for multimorbidity in multivariate analyses (all P < .05). Every 1-component increase in frailty was also found to significantly increase the risk for health care utilization [any outpatient visit: adjusted odds ratio (OR) 1.30, 95% confidence interval (CI) 1.14–1.48; number of outpatient visits: adjusted incident rate ratio (IRR) 1.34, 95% CI 1.18–1.53; any inpatient visit: adjusted OR 1.44, 95% CI 1.22–1.71; number of inpatient visits: adjusted IRR 1.40, 95% CI 1.20–1.62; inpatient length of stay: adjusted IRR 1.50, 95% CI 1.18–1.92]. The preceding associations were similarly observed irrespective of gender.Conclusions and ImplicationsFrailty is a significant predictor for increased health care utilization among community-dwelling older adults. These findings have important implications for routine clinical practice and public health investment. Early screening and intervention for potentially modifiable frailty could translate into considerable savings for households and health care systems.     

Staffing and Protective Equipment Access Mitigated COVID-19 Penetration and Spread in US Nursing Homes During the Third Surge

ObjectivesDuring the last quarter of 2020—despite improved distribution of personal protective equipment (PPE) and knowledge of COVID-19 management—nursing homes experienced the greatest increases in cases and deaths since the pandemic's beginning. We sought to update COVID-19 estimates of cases, hospitalization, and mortality and to evaluate the association of potentially modifiable facility-level infection control factors on odds and magnitude of COVID-19 cases, hospitalizations, and deaths in nursing homes during the third surge of the pandemic.DesignCross-sectional analysis.Setting and ParticipantsFacility-level data from 13,156 US nursing home facilities.MethodsTwo series of multivariable logistic regression and generalized linear models to examine the association of infection control factors (personal protective equipment and staffing) on incidence and magnitude, respectively, of confirmed COVID-19 cases, hospitalizations, and deaths in nursing home residents reported in the last quarter of 2020.ResultsNursing homes experienced steep increases in COVID-19 cases, hospitalizations, and deaths during the final quarter of 2020. Four-fifths (80.51%; n = 10,592) of facilities reported at least 1 COVID-19 case, 49.44% (n = 6504) reported at least 1 hospitalization, and 49.76% (n = 6546) reported at least 1 death during this third surge. N95 mask shortages were associated with increased odds of at least 1 COVID-19 case [odds ratio (OR) 1.21, 95% confidence interval (CI) 1.05-1.40] and hospitalization (1.26, 95% CI 1.13-1.40), as well as larger numbers of hospitalizations (1.11, 95% CI 1.02-1.20). Nursing aide shortages were associated with lower odds of at least 1 COVID-19 death (1.23, 95% CI 1.12-1.34) and higher hospitalizations (1.09, 95% CI 1.01-1.17). The number of nursing hours per resident per day was largely insignificant across all outcomes. Of note, smaller (<50-bed) and midsized (50- to 150-bed) facilities had lower odds yet higher magnitude of all COVID outcomes. Bed occupancy rates >75% increased odds of experiencing a COVID-19 case (1.48, 95% CI 1.35-1.62) or death (1.25, 95% CI 1.17-1.34).Conclusions and ImplicationsAdequate staffing and PPE—along with reduced occupancy and smaller facilities—mitigate incidence and magnitude of COVID-19 cases and sequelae. Addressing shortcomings in these factors is critical to the prevention of infections and adverse health consequences of a next surge among vulnerable nursing home residents.     

Pregnancy outcomes among visually impaired women in Washington State, 1987–2014

BackgroundWomen with visual impairment may have reduced ability to access standard care resources, however, information on their pregnancy and neonatal outcomes is limited.ObjectiveTo assess risk of adverse pregnancy and neonatal outcomes among visually impaired women in Washington State from 1987 to 2014.MethodsWe conducted a retrospective cohort study using linked Washington State birth/fetal death hospital discharge records to compare outcomes among women with and without visual impairment noted at their delivery hospitalization. Pregnancy conditions and outcomes evaluated included gestational diabetes, pre-eclampsia, labor induction and cesarean delivery. Neonatal outcomes included preterm delivery and birth weight <2500 g. We assessed length of maternal and infant delivery hospitalization. We performed Poisson regression to estimate relative risks (RR) and 95% confidence intervals (CIs) for each outcome, adjusting for year of delivery, maternal age, and parity.ResultsMost adverse pregnancy and neonatal outcomes were similar for visually impaired (N = 232) and comparison women (N = 2362). However, visually impaired women had increased risks of severe pre-eclampsia (RR 3.77, 95% CI 1.69–8.43), labor induction (RR 1.33, 95% CI 1.10–1.61) and preterm delivery (RR 1.60, 95% CI 1.06–2.42). They were also more likely to have delivery hospitalizations of 3 or more days following a vaginal (RR 1.86, 95% CI 1.41–2.47). Among cesarean deliveries, infants of visually impaired women had increased risk (RR 1.24, 95% CI 1.02–1.51) of hospitalization for 3 or more days postpartum.ConclusionOur findings may be useful for obstetric providers in counseling their visually impaired patients.     

The Impact of Home-Based Primary Care on Outcomes Among Older Adults in South Korea

ObjectivesAlthough Korea issued a law and developed benefits of National Health Insurance (NHI) to enable the provision of home-based primary care (HBPC) along with implementation of a pilot project for community care for older adults in August 2019, the outcomes of HBPC services were not surveyed in Korea. This study aimed to assess the outcomes of HBPC among older adults.DesignAnalyses were conducted using data from the National Health Insurance Service in connection with administrative survey data. Difference-in-differences analysis was performed using a generalized estimating equation and Cox proportional hazards model.Setting and ParticipantsOverall, 538 older adults who used HBPC services in a pilot project for community care and 2059 propensity score–matched older individuals who did not use HBPC services in Korea were included.MethodsThe length of home stay, total costs of NHI, hospitalizations, and admission to long-term care (LTC) facilities were measured as outcomes, and the outcomes of the participants were compared to those of the control group.ResultsThe findings indicated an increase of 8.3 days (95% CI 2.1-14.5) in the length of home stay and a reduction of US$1241 (95% CI −2342 to −139) in total costs of NHI among older adults who used HBPC services compared to the control group. The odds ratio for rates of hospitalization among older adults who utilized HBPC services was 0.77 (95% CI 0.60-0.98) and the hazard ratio for the admission of LTC facilities was 0.12 (95% CI 0.04-0.32) in comparison to the control group.Conclusions and ImplicationsThe HBPC intervention has resulted in an increased length of home stay and reduced total costs, hospitalizations, and admission to LTC facilities among Korean older adults. In the future, new HBPC models must be developed to provide interprofessional team–based HBPC services with a standardized protocol of service provision.     

Trends in U.S. hospitalizations and inpatient deaths from pneumonia and influenza, 1996–2011

BackgroundTo reduce excess morbidity and mortality of pneumonia and influenza (PI), the Advisory Committee on Immunization Practices has recommended the use of 7-valent pneumococcal conjugate vaccine (PCV7), and incrementally expanded the target group for annual influenza vaccination of healthy persons, to ultimately include all persons ≥6 months of age without contraindications as of the 2010–2011 influenza season. We aimed to capture broader epidemiologic changes by looking at PI collectively.MethodsUsing interrupted time series, we evaluated the changes in the rates of PI hospitalization and inpatient death across three periods defined according to the changes in vaccination policy. We assessed linear trends adjusting for seasonality, sex, and age group, allowing for differential impact across age groups. PI hospitalizations were defined as a principal diagnosis of PI, or a principal diagnosis of sepsis or respiratory failure, accompanied by a secondary diagnosis of PI.ResultsOverall annual rates of PI hospitalizations and inpatient deaths declined by 95 per 100,000 (95% CI: 45–145) and by 4.4 per 100,000 (95% CI: 0.9–7.8), respectively. This translates to 295,000 fewer PI hospitalizations and 13,600 fewer PI inpatient deaths than expected based on the average rates from 1996 through 1999. PI hospitalizations dropped the most among seniors aged 65+ by 487 per 100,000, followed by children aged <2, by 228 per 100,000. PI inpatient deaths declined most among seniors aged 65+, by 25.3 per 100,000.ConclusionsIn this nationally representative study, PI hospitalizations and inpatient deaths decreased in U.S. between 1996 and 2011. There is a temporal association with the introduction and widespread use of pneumococcal conjugate vaccines, and the expansion of the target group for annual influenza vaccination to include all persons ≥6 months of age, while it is difficult to attribute these changes directly to specific vaccines used in this era.     

Seasonal influenza vaccination is associated with reduced risk of death among Medicare beneficiaries☆

BackgroundInfluenza causes substantial mortality, especially among older persons. Influenza vaccines are rarely more than 50% effective and rarely reach more than half of the US Medicare population, which is primarily an aged population. We wished to estimate the association between vaccination and mortality reduction.MethodWe used the US Center for Medicare and Medicaid Services (CMS) DataLink Project to determine vaccination status and timing during the 2017–2018 influenza season for more than 26 million Medicare enrollees. Patient-level demographic, health, co-morbidity, hospitalization, vaccination, and healthcare utilization claims data were supplied as covariates to general linear models in order to isolate and estimate the association between participation in the vaccination program and relative risk of death.FindingsThe 2017–2018 seasonal influenza vaccine reduced (Relative Risk Ratio [RRR] 0.936 [95% CI = 0.918–0.954]) the risk of all-cause death among beneficiaries following a hospitalization for sepsis and moreover the risk of death without a prior hospitalization during the 2.5-month outcome window (RRR 0.870 [95% CI = 0.853–0.887]). We estimate the number needed to vaccinate (NNV) to prevent a death in the ten-week outcome window is between 1,515 beneficiaries (95% CI = 1,351–1,754; derived from the average treatment effect of augmented inverse probability weighting) and 1,960 beneficiaries (95% CI = 1,695–2,381; derived from the average marginal effect of logistic regression). Among beneficiaries requiring hospitalization, the greatest death risk reduction accrued to those 85 + years of age who were hospitalized with sepsis, RRR 0.92 [95% CI = 0.89–0.95]. No apparent benefit was realized by beneficiaries who required custodial (nursing home) care.InterpretationSeasonal influenza immunization is associated with relative reduction of death risk among non-institutionalized Medicare beneficiaries.FundingAll authors are full-time or contractual employees of the United States Federal Government, Department of Health and Human Services, the funding agency.     

National Early Warning Scores Following Emergency Hospital Transfer: Implications for Care Home Residents

ObjectiveCare home residents have high rates of hospital admission. The UK National Early Warning Score (NEWS2) standardizes the secondary care response to acute illness. However, the ability of NEWS2 to predict adverse health outcomes specifically for care home residents is unknown. This study explored the relationship between NEWS2 on admission to hospital and resident outcome 7 days later.DesignRepeated cross-sectional study.Setting and ParticipantsData on UK care home residents admitted to 160 hospitals in two 24-hour periods (2019 and 2020).MethodChi-squared and Kruskal-Wallis tests, and multinomial regression were used to explore the association between low (score ≤2), intermediate (3–4), high (5–6), and critically high (≥7) NEWS2 on admission and each of the following: discharge on day of admission, admission and discharge within 7 days, prolonged hospital admission (>7 days), and death.ResultsFrom 665 resident admissions across 160 hospital sites, NEWS2 was low for 54%, intermediate for 18%, high for 13%, and critically high for 16%. The 7-day outcome was 10% same-day discharge, 47% admitted and subsequently discharged, 34% remained inpatients, and 8% died. There is a significant association between NEWS2 and these outcomes (P < .001). Compared with those with low NEWS2, residents with high and critically high NEWS2 had 3.6 and 9.5 times increased risk of prolonged hospitalization [relative risk ratio (RRR) 3.56; 95% CI 1.02–12.37; RRR 9.47; CI 2.20–40.67], respectively. The risk of death was approximately 14 times higher for residents with high NEWS2 (RRR 13.62; CI 3.17–58.49) and 54 times higher (RRR 53.50; CI 11.03–259.54) for critically high NEWS2.Conclusion and ImplicationsHigher NEWS2 measurements on admission are associated with an increased risk of hospitalization up to 7 days duration, prolonged admission, and mortality for care home residents. NEWS2 may have a role as an adjunct to acute care decision making for hospitalized residents.     

Introducing Goals of Patient Care in Residential Aged Care Facilities to Decrease Hospitalization: A Cluster Randomized Controlled Trial

ObjectivesThe “Goals of Patient Care” (GOPC) process uses shared decision making to incorporate residents' prior advance care planning (ACP) or preferences into medical treatment orders, guiding health care decisions at a time of clinical deterioration should they be unable to voice their opinions. The objective was to determine whether GOPC medical treatment orders were more effective than ACP alone in preventing emergency department (ED) visits (no hospitalization), ED visits (with hospitalization), and deaths outside the residential aged care facility (RACF).DesignThe study was a prospective cluster randomized controlled trial, with the intervention being the completion of GOPC process by a geriatrician, following a shared decision-making process, incorporating ACP documents or residents' preferences.Setting and participantsThe study took place in 6 RACFs in Northern Metropolitan Melbourne, Australia. Eligible participants included all permanent residents in participating RACFs for whom written informed consent could be obtained.MeasuresThe primary outcome was the effect on ED visits and hospitalizations at 6 months. Secondary outcomes included a difference in hospitalization rates at 3 and 12 months, total hospital bed-days, and in-RACF and in-hospital mortality rates.ResultsMore than 75% of residents participated, 181 randomized to Intervention and 145 to Control. The intervention did not result in a statistically significant change at 6 months; however, at 12 months, it reached statistical significance with 40% reduction in ED visits and hospitalizations compared with Control, with an incident rate ratio 0.63 [95% confidence interval (CI) 0.41-0.99, P = .044]. Mortality rates show increased likelihood of dying in the RACF, with statistical significance at 6 months at a relative risk ratio of 2.19 (95% CI 1.16-4.14, P = .016).Conclusions and implicationsIn the RACF population, GOPC medical treatment orders were more effective than ACP alone for decreasing hospitalization and likelihood of dying outside the RACF. GOPC should be considered by both RACF staff and health services to decrease hospitalization and in-hospital mortality.     

Impact of rotavirus vaccination on diarrhea-related hospitalizations in São Paulo State,Brazil

IntroductionFollowing introduction of routine infant rotavirus vaccination, severe diarrhea hospitalization rates declined among children aged <5 years throughout Brazil. Ensuring equity of rotavirus vaccine impact is important in countries that self-finance immunization programs. The objective of this study was to examine rotavirus vaccine impact on diarrhea admission rates among children aged <5 years in Brazil's public health system, according to area-based measures of human development in the state of São Paulo, Brazil.MethodsEcological analysis of public health system hospitalization rates for acute gastroenteritis among children aged <5 years in the state of São Paulo, Brazil, according to five categories of municipal development based on a modified Human Development Index for municipalities. Acute gastroenteritis hospitalization rates among children aged <5 years after national rotavirus vaccine introduction (2008–2011) were compared to rates in pre-vaccine years (2000–2005) to calculate percent decline in rates (1 − rate ratio) and 95% confidence intervals (CI) for each municipal development category. Direct hospitalization costs during the two periods were compared.ResultsAnnual rates declined by 40% (95% CI, 39–42%) from 631 diarrhea hospitalizations per 100,000 person years pre-rotavirus vaccination to 377 per 100,000 post-vaccination among children aged <5 years and 50% (95% CI, 48–52%) from 1009 to 505 per 100,000 among infants. Highest rates were observed in least developed municipalities. Significant declines of 26–52% among children <5 years and 41–63% among infants were observed in all categories of municipal development. Lower diarrhea hospitalization rates resulted in annual savings of approximately 2 million USD for the state of São Paulo. Savings in direct hospitalization costs benefitted municipalities in all five categories.ConclusionThe introduction of rotavirus vaccination was associated with substantial reductions of diarrhea-related admissions at all levels of municipal development in São Paulo State, Brazil.     

Factors associated with repeated influenza vaccine uptake among aged care staff in an Australian sample from 2017 to 2019

Background/AimInfluenza vaccination is strongly recommended every year for aged care staff to protect themselves and minimise risk of transmission to residents. This study aimed to determine the factors associated with repeated annual influenza vaccine uptake among Australian aged care staff from 2017 to 2019.MethodsDemographic, medical and vaccination data collected from the staff, who participated in an observational study from nine aged care facilities under a single provider in Sydney Australia, were analysed retrospectively. Based on the pattern of repeated influenza vaccination from 2017 to 2019, three groups were identified: (1) unvaccinated all three years; (2) vaccinated occasionally(once or twice) over three years; and (3)vaccinated all three years. Multinomial logistic regression analysis was performed to better understand the factors associated with the pattern of repeated influenza vaccination.ResultsFrom a total of 138 staff, between 2017 and 2019, 28.9 % (n = 40) never had a vaccination, while 44.2 % (n = 61) had vaccination occasionally and 26.8 % (n = 37) had vaccination all three years. In the multinomial logistic regression model, those who were<40 years old (OR = 0.57, 95 % CI: 0.19–0.90, p < 0.05) and those who were current smokers (OR = 0.20; 95 % CI: 0.03–0.76, p < 0.05) were less likely to have repeated vaccination for all three years compared to the unvaccinated group. Those who were<40 years old (OR = 0.61; 95 % CI: 0.22–0.68, p < 0.05) and those who were born overseas (OR = 0.50; 95 % CI:0.27–0.69, p < 0.05) were more likely to be vaccinated occasionally compared to the unvaccinated group.ConclusionThe significant predictors of repeated vaccine uptake across the three-year study period among aged care staff were age, smoking status and country of birth (Other vs Australia). Targeted interventions towards the younger age group (<40 years old), smokers and those who were born overseas could improve repeated influenza vaccination uptake in the aged care workforce.     

The Effect of Advance Care Planning Intervention on Hospitalization Among Nursing Home Residents: A Systematic Review and Meta-Analysis

ObjectiveTo evaluate the effect of advance care planning (ACP) interventions on the hospitalization of nursing home residents.DesignSystematic review and meta-analysis.Setting and ParticipantsNursing homes and nursing home residents.MethodsA literature search was systematically conducted in 6 electronic databases (Embase, Ovid MEDLINE, Cochrane Library, CINAHL, AgeLine, and the Psychology & Behavioral Sciences Collection), in addition to hand searches and reference list checking; the articles retrieved were those published from 1990 to November 2021. The eligible studies were randomized controlled trials, controlled trials, and pre-post intervention studies describing original data on the effect of ACP on hospitalization of nursing home residents; these studies had to be written in English. Two independent reviewers appraised the quality of the studies and extracted the relevant data using the Joanna Briggs Institute abstraction form and critical appraisal tools. A study protocol was registered in PROSPERO (CRD42022301648).ResultsThe initial search yielded 744 studies. Nine studies involving a total of 57,180 residents were included in the review. The findings showed that the ACP reduced the likelihood of hospitalization [relative risk (RR) 0.54, 95% CI 0.47-0.63; I² = 0%)], it had no effect on emergency department (ED) visits (RR 0.60, 95% CI 0.31-1.42; I² = 99), hospice enrollment (RR 0.98, 95% CI 0.88-1.10; I² = 0%), mortality (RR 0.83, 95% CI 0.68-1.00; I² = 4%), and satisfaction with care (standardized mean difference: ?0.04, 95% CI ?0.14 to ?0.06; I² = 0%).Conclusion and ImplicationsACP reduced hospitalizations but did not affect the secondary outcomes, namely, ED visits, hospice enrollment, mortality, and satisfaction with care. These findings suggest that policy makers should support the implementation of ACP programs in nursing homes. More robust studies are needed to determine the effects of ACP on ED visits, hospice enrollment, mortality, and satisfaction with care.     

Evaluation of a Home-Based,Nurse Practitioner–led Advanced Illness Care Program

ObjectivesIn the United States, people with serious illness often experience gaps and discontinuity in care. Gaps are frequently exacerbated by limited mobility, need for social support, and challenges managing multiple comorbidities. The Advanced Illness Care (AIC) Program provides nurse practitioner–led, home-based care for people with serious or complex chronic illnesses that specifically targets palliative care needs and coordinates with patients’ primary care and specialty health care providers. We sought to investigate the effect of the AIC Program on hospital encounters [hospitalizations and emergency department (ED) visits], hospice conversion, and mortality.DesignRetrospective nearest-neighbor matching.Setting and ParticipantsPatients in AIC who had ≥1 inpatient stay within the 60 days prior to AIC enrollment to fee-for-service Medicare controls at 9 hospitals within one health system.MethodsWe matched on demographic characteristics and comorbidities, with exact matches for diagnosis-related group and home health enrollment. Outcomes were hospital encounters (30- and 90-day ED visits and hospitalizations), hospice conversion, and 30- and 90-day mortality.ResultsWe included 110 patients enrolled in the AIC Program matched to 371 controls. AIC enrollees were mean age 77.0, 40.9% male, and 79.1% white. Compared with controls, AIC enrollees had a higher likelihood of ED visits at 30 [15.1 percentage points, confidence interval (CI) 4.9, 25.3; P = .004] and 90 days (27.8 percentage points, CI 16.0, 39.6; P < .001); decreased likelihood of hospitalization at 30 days (11.4 percentage points, CI –17.7, −5.0; P < .001); and a higher likelihood of converting to hospice (22.4 percentage points, CI 11.4, 33.3; P < .001).ConclusionsThe AIC Program provides care and coordination that the home-based serious illness population may not otherwise receive.ImplicationsBy identifying and addressing care needs and gaps in care early, patients may avoid unnecessary hospitalizations and receive timely hospice services as they approach the end of life.     

Longitudinal,population-based cohort study of prenatal influenza vaccination and influenza infection in childhood

BackgroundInfluenza vaccination is recommended to protect mothers and their infants from influenza infection. Few studies have evaluated the health impacts of in utero exposure to influenza vaccine among children more than six months of age.MethodsWe used probabilistically linked administrative health records to establish a mother–child cohort to evaluate the risk of influenza and acute respiratory infections associated with maternal influenza vaccination. Outcomes were laboratory-confirmed influenza (LCI) and hospitalization for influenza or acute respiratory infection (ARI). Adjusted hazard ratios (aHRs) accounted for child’s Aboriginal status and were weighted by the inverse-probability of treatment.Results14,396 (11.5%) children were born to vaccinated mothers. Maternally vaccinated infants aged < 6 months had lower risk of LCI (aHR: 0.33; 95% CI: 0.13, 0.85), influenza-associated hospitalization (aHR: 0.39; 95% CI: 0.16, 0.94) and ARI-associated hospitalization (aHR: 0.85; 95% CI: 0.77, 0.94) compared to maternally unvaccinated infants. With the exception of an increased risk of LCI among children aged 6 months to < 2 years old following first trimester vaccination (aHR: 2.28; 95% CI: 1.41, 3.69), there were no other differences in the risk of LCI, influenza-associated hospitalization or ARI-associated hospitalization among children aged > 6 months.ConclusionStudy results show that maternal influenza vaccination is effective in preventing influenza in the first six months and had no impact on respiratory infections after two years of age.
