Reducing potentially preventable hospital transfers: results from a thirty nursing home collaborative

BackgroundNursing home (NH) residents experience frequent hospital transfers, some potentially avoidable. The objective of this report is to describe a replication of the Interventions to Reduce Acute Care Transfers program among member facilities of a New York City area NH provider association (INTERACT NY) and estimate its effect on hospital transfers.MethodsINTERACT is a program that provides tools and strategies to assist NH staff in early identification, communication, and documentation of changes in resident status. Funding was obtained from a New York State health workforce training grant to conduct 13 INTERACT education and training sessions in 2010–2011. INTERACT NY session topics included the implementation process; use of its simple standardized communication tools, advance care planning tools, care paths, and change in condition support tools; quality review of hospital transfers; exercises for refining clinical skills; teamwork; and lessons learned. Sessions engaged NH executives, department heads, front-line nursing staff and their labor union, and staff from NHs’ partner hospitals. Pre-/post- INTERACT NY hospitalization rates per 1000-resident days were compared using paired t-tests, stratified by level of facility engagement with the program and by baseline hospitalization rates.ResultsAll 100% of participating NHs were non-profit or public. Those with complete evaluation data had 377 beds on average. There were a total of 333 attendees of the program (mean 25.6 per session; mean 11.1 per facility over the course of the program; range 1–44 per facility). The most common attendees in order of frequency were (1) nurse administrators, (2) unit-based nurses, (3) medical directors and attending physicians, (4) nursing home administrators, (5) certified nursing assistants, and (6) case managers and social workers. Sixteen nursing homes implemented at least one INTERACT tool. Overall, there was a nonsignificant 10.6% reduction in hospital admissions from 4.07 to 3.64 per 1000 resident-days from pre- to post-INTERACT NY (P = .332). Among nursing homes with high engagement there was a nonsignificant 14.3% reduction in hospital admissions from 4.19 to 3.59 per 1000 resident-days (P = 0.213). Finally, among nursing homes in the highest tertile of baseline (pre-INTERACT NY) hospital admission rate, there was a nonsignificant 27.2% reduction in hospital admissions from 7.32 to 5.33 per 1000 resident-days (P = .102). Planning and implementation lessons from INTERACT NY leaders and participants are reported.ConclusionsINTERACT NY, a novel collaborative training program, resulted in good uptake of the INTERACT tools and processes among its member nursing homes. Changes in hospitalization rates associated with INTERACT NY were similar to those observed in previous implementations of INTERACT. The program addresses a growing interest in reducing potentially preventable hospital admissions among nursing home residents and providing alternatives to hospital care through standardized approaches to communication, early identification of clinical issues, decision-support, and support for partnerships between acute and post-acute care providers.     

Effectiveness of Hip Protectors to Reduce Risk for Hip Fracture from Falls in Long-Term Care

ObjectiveTo generate evidence of the effectiveness of hip protectors to minimize risk of hip fracture at the time of falling among residents of long-term care (LTC) by contrasting rates of hip fractures between falls with and without hip protectors.DesignA 12-month, retrospective cohort study. We retrospectively reviewed fall incident reports recorded during the 12 months prior to baseline in participating homes.Setting and participantsA population-based sample comprising all residents from 14 LTC homes owned and operated by a single regional health authority, who experienced at least 1 recorded fall during the 12-month study.ResultsAt baseline, the pooled mean (standard deviation) age of residents in participating homes was 82.7 (11.3) years and 68% were female. Hip protectors were worn in 2108 of 3520 (60%) recorded falls. Propensity to wear hip protectors was associated with male sex, cognitive impairment, wandering behavior, cardiac dysrhythmia, use of a cane or walker, use of anti-anxiety medication, and presence of urinary and bowel incontinence. The incidence of hip fracture was 0.33 per 100 falls in falls with hip protectors compared with 0.92 per 100 falls in falls without hip protectors, representing an unadjusted relative risk (RR) of hip fracture of 0.36 (95% confidence interval 0.14–0.90, P = .029) between protected and unprotected falls. After adjusting for propensity to wear hip protectors, the RR of hip fracture was 0.38 (95% confidence interval 0.14–0.99, P = .048) during protected vs unprotected falls.Conclusions and implicationsHip protectors were worn in 60% of falls, and the risk of hip fracture was reduced by nearly 3-fold by wearing a hip protector at the time of falling. Given that most clinical trials have failed to attain a similar level of adherence, our findings support the need for future research on the benefits of dissemination and implementation strategies to maximize adherence with hip protectors in LTC.     

Association of Deprescribing With Reduction in Mortality and Hospitalization: A Pragmatic Stepped-Wedge Cluster-Randomized Controlled Trial

ObjectivesDeprescribing has gained awareness recently, but the clinical benefits observed from randomized trials are limited. The aim of this study was to examine the effectiveness of a pharmacist-led 5-step team-care deprescribing intervention in nursing homes to reduce falls (fall risks and fall rates). Secondary aims include reducing mortality, number of hospitalized residents, pill burden, medication cost, and assessing the deprescribing acceptance rate.DesignPragmatic multicenter stepped-wedge cluster randomized controlled trial.Setting and ParticipantsResidents across 4 nursing homes in Singapore were included if they were aged 65 years and above, and taking 5 or more medications.MethodsThe intervention involved a 5-step deprescribing intervention, which involved a multidisciplinary team-care medication review with pharmacists, physicians, and nurses (in which pharmacists discussed with other team members the feasibility of deprescribing and implementation using the Beers and STOPP criteria) or to an active waitlist control for the first 3 months.ResultsTwo hundred ninety-five residents from 4 nursing homes participated in the study from February 2017 to March 2018. At 6 months, the deprescribing intervention did not reduce falls. Subgroup analysis showed that intervention reduced fall risk scores within the deprescribing-naïve group by 0.18 (P = .04). Intervention was associated with a reduction in mortality [hazard ratio (HR) 0.16, 95% confidence interval 0.07, 0.41; P < .001] and number of hospitalized residents (HR 0.16, 95% CI 0.10, 0.26; P < .001). Pre-post analysis witnessed a reduction in pill burden at the end of the study, and a conservative daily cost saving estimate of US$11.42 (SG$15.65) for the study population. Approximately three-quarters of deprescribing interventions initiated by the pharmacists were accepted by the physicians.Conclusions and ImplicationsMultidisciplinary medication review–directed deprescribing was associated with reductions in mortality and number of hospitalized residents in nursing homes and should be considered for all nursing home residents.     

A short-term, multicomponent infection control program in nursing homes: a cluster randomized controlled trial

ObjectivesTo assess the impact of a hygiene-encouragement program on reducing infection rates (primary end point) by 5%.DesignA cluster randomized study was carried out over a 5-month period.Settings and participantsFifty nursing homes (NHs) with 4345 beds in France were randomly assigned by stratified-block randomization to either a multicomponent intervention (25 NHs) or an assessment only (25 NHs).InterventionThe multicomponent intervention was targeted to caregivers and consisted of implementing a bundle of infection prevention consensual measures. Interactive educational meetings using a slideshow were organized at the intervention NHs. The NHs were also provided with color posters emphasizing hand hygiene and a kit that included hygienic products such as alcoholic-based hand sanitizers. Knowledge surveys were performed periodically and served as reminders.MeasurementsThe primary end point was the total infection rate (urinary, respiratory, and gastrointestinal infections) in those infection cases classified either as definite or probable. Analyses corresponded to the underlying design and were performed according to the intention-to-treat principle. This study was registered (#NCT01069497).ResultsForty-seven NHs (4515 residents) were included and followed. The incidence rate of the first episode of infection was 2.11 per 1000 resident-days in the interventional group and 2.15 per 1000 resident-days in the control group; however, the difference between the groups did not reach statistical significance in either the unadjusted (Hazard Ratio [HR] = 1.00 [95% confidence interval (CI) 0.89–1.13]; P = .93]) or the adjusted (HR = 0.99 [95% CI 0.87–1.12]; P = .86]) analysis.ConclusionDisentangling the impact of this type of intervention involving behavioral change in routine practice in caregivers from the prevailing environmental and contextual determinants is often complicated and confusing to interpret the results.     

Predictors of Serious Consequences of Falls in Residential Aged Care: Analysis of More Than 70,000 Falls From Residents of Bavarian Nursing Homes

Background/ObjectiveFalls are common in nursing homes and cause a high burden of injuries. The objective of this study was to analyze factors associated with serious consequences of falls in nursing home residents.DesignProspective observational study.SettingFalls were recorded over 1 year, covering all residents from 528 nursing homes in Bavaria, Germany.ParticipantsThe database consisted of 70,196 falls.MeasurementsThe standardized form included information about date, time, sex, age, functional status, location of fall, activity leading to the fall, footwear, and about potential consequences, such as transfer to hospital or a suspected fracture. Transfer to hospital was the main outcome and served as surrogate for a serious fall. The association of potential risk factors with hospital transfer after a fall was estimated in multiple logistic regression models.ResultsSerious falls were associated with increasing age, being female, and less restricted functional status. Walking compared with transferring, and particularly the morning hours were also associated with a serious fall. Compared with midday, for example, the time period between 6 am and 8 am was associated with a more than 60% increased chance of transfer to hospital. Inappropriate footwear and weekends were associated with serious falls only in women.ConclusionSome observed factors or indicators associated with transfer to hospital are modifiable and targeted interventions may reduce injuries or costs after a fall.     

Physician Availability in Long-Term Care and Resident Hospital Transfer: A Retrospective Cohort Study

ObjectivesTo investigate whether same-day physician access in long-term care homes reduces resident emergency department (ED) visits and hospitalizations.DesignRetrospective cohort study.Setting and participants161 long-term care homes in Ontario, Canada, and 20,624 residents living in those homes.MethodsWe administered a survey to Ontario long-term care homes from March to May 2017 to collect their typical wait time for a physician visit. We linked the survey to administrative databases to capture other long-term care home characteristics, resident characteristics, hospitalizations, and ED visits. We defined a cohort of residents living in survey-respondent homes between January and May 2017 and followed each resident for 6 months or until discharge or death.We estimated negative binomial regression models on counts of hospitalizations and ED visits with random intercepts for long-term care homes. We controlled for residents' sociodemographic and illness characteristics, long-term care home size, chain status, rurality, and nurse practitioner access.ResultsFifty-two homes (32%) reported same-day physician access. Among residents of homes with same-day physician access, 9% had a hospitalization and 20% had an ED visit during follow-up. In contrast, among residents in homes without same-day access, 12% were hospitalized and 22% visited an ED.The adjusted hospitalization and ED rates among residents of homes with same-day physician access were 21% lower (rate ratio = 0.79, P = .02) and 14% lower (rate ratio = 0.86, P = .07), respectively, than residents of other homes. We estimate that nearly 1 in 6 resident hospitalizations could be prevented if all long-term care homes had same-day physician access.Conclusions and implicationsResidents of long-term care homes with same-day physician access experience lower hospitalization and ED visit rates than residents in homes that wait longer for physicians, even after adjusting for important resident and home characteristics. Improved on-demand access to physicians has the potential to reduce hospital transfer rates.     

Changes in Long-Term Care Markets: Assisted Living Supply and the Prevalence of Low-Care Residents in Nursing Homes

ObjectivesTo assess the effect of changes in assisted living (AL) capacity within a market on prevalence of residents with low care needs in nursing homes.DesignRetrospective, longitudinal analysis of nursing home markets.Setting and participantsTwelve thousand two hundred fifity-one nursing homes in operation during 2007 and 2014.MeasurementsWe analyzed the percentage of residents in a nursing home who qualified as low-care. For each nursing home, we constructed a market consisting of AL communities, Medicare beneficiaries, and competing nursing homes within a 15-mile radius. We estimated the effect of change in AL beds on prevalence of low-care residents using multivariate linear models with year and nursing home fixed effects.ResultsThe supply of AL beds increased by an average 258 beds per nursing home market (standard deviation = 591) during the study period. The prevalence of low-care residents decreased from an average of 13.0% (median 10.5%) to 12.2% (median 9.5%). In adjusted models, a 100-bed increase in AL supply was associated with a decrease in low-care residents of 0.041 percentage points (P = .026), controlling for changes in market and nursing home characteristics, county demographics, and year and nursing home fixed effects. In markets with a high percentage of its Medicare beneficiaries (≥14%) dual eligible for Medicaid, the effect of AL is stronger, with a 0.066–percentage point decrease per 100 AL beds (P = .026) vs a 0.016–percentage point decrease in low-duals markets (P = .48).Conclusions and implicationsOur analysis suggests that some of the growth in AL capacity serves as a substitute for nursing homes for patients with low care needs. Furthermore, the effects are concentrated in markets with an above-average proportion of beneficiaries with dual Medicaid eligibility.     

Progressive Resistance and Balance Training for Falls Prevention in Long-Term Residential Aged Care: A Cluster Randomized Trial of the Sunbeam Program

Background

Falls prevention is an international priority, and residents of long-term aged care fall approximately 3 times more often than community dwellers. There is a relative scarcity of published trials in this setting.

Structural and process indicators of nutritional care: a comparison between Austrian hospitals and nursing homes

ObjectiveThe aim of this study was to describe and compare structural and process indicators of nutritional care in Austrian hospitals and nursing homes.MethodsA multicenter, cross-sectional study was performed using a standardized and tested questionnaire. Data were collected on patient and institutional levels of hospitals and nursing homes.ResultsData from 18 Austrian hospitals (n = 2326 patients) and 18 Austrian nursing homes (n = 1487 residents) were collected. The prevalence of malnutrition was 23.2% in hospitals and 26.2% in nursing homes. All hospitals and 83.3% of the nursing homes employed dietitians. Guidelines for the prevention and treatment of malnutrition were used infrequently. Nutritional screening at admission was performed in 62.6% of the hospitalized patients and 93.4% of the nursing home residents. Nutritional screening tools were used in 28.9% of the nursing home residents and 14.5% of the hospitalized patients. Oral nutritional support was preferred to enteral and parenteral nutrition in the two settings. Dietitians were consulted in 27.5% of the malnourished hospitalized patients and 74.7% of the malnourished nursing home residents.ConclusionThe study demonstrated that nursing homes fulfilled more structural indicators and performed nutritional screening at admission more often than hospitals. Nevertheless, the prevalence of malnutrition was high in the two settings and a substantial number of malnourished patients/residents received no nutritional intervention at all. These results show the necessity for improvements in the nutritional care in Austria, for instance, through the routine use of nutritional screening tools followed by tailored nutritional interventions in patients/residents in need.     

Anticholinergic Drug Use and Negative Outcomes Among the Frail Elderly Population Living in a Nursing Home

AimIncreasing evidence from experimental studies and clinical observations suggests that drugs with anticholinergic properties can cause physical and mental impairment. The aim of the present study was to evaluate the relationship between the use of drugs with anticholinergic activity and negative outcomes in older nursing home residents.MethodsWe used data from the database of the U.L.I.S.S.E project (Un Link Informatico sui Servizi Sanitari Esistenti per l'Anziani), a prospective multicenter observational study. Patients from 31 facilities in Italy were assessed at baseline and at 6 and 12 months by trained personnel, using the Minimum Data Set for Nursing Home (MDS-NH). The only exclusion criterion was age younger than 65 years. The Anticholinergic Risk Scale (ARS), a list of commonly prescribed drugs with potential anticholinergic effects, was used to calculate the anticholinergic load.ResultsA total population of 1490 patients was analyzed; almost half of the sample (48%) was using drugs with anticholinergic properties. The population of patients with ARS 1 or higher had a higher comorbidity index (P < .003) and greater cognitive impairment (CPS 5–6) (P < .007). They were more likely to suffer from heart failure, Parkinson disease, depression, anxiety, and schizophrenia. In multivariate analysis, a higher score in the ARS scale was associated with a greater likelihood of functional decline (described as the loss of ≥1 ADL point) (odds ratio [OR] 1.13; confidence interval [CI] 1.03–1.23), to a higher rate of falls (OR 1.26; CI 1.13–1.41), and to a higher incidence of delirium (OR 1.16; CI 1.02–1.32) during a 1-year follow-up.ConclusionsThe use of medications with anticholinergic properties is common among older nursing home residents. Our results suggest that among older nursing home residents the use of anticholinergic drugs is associated with important negative outcomes, such as functional decline, falls, and delirium.     

Exploring variation in rates of polypharmacy across long term care homes

ObjectiveUse of multiple, concurrent drug therapies, often referred to as polypharmacy, is a concern in the long term care (LTC) setting, where frail older adults are particularly at risk for adverse events. We quantified the scope of this practice by exploring variation in the use of nine or more drug therapies across LTC homes.DesignCross-sectional analysis of LTC home census data.SettingAll LTC homes in Ontario, Canada.ParticipantsA total of 64,394 LTC residents aged 66 years and older residing in 589 LTC homes in the fall of 2005.MeasurementsFacility-level rates of polypharmacy were compared with rates of use of Beers criteria and antipsychotic drug therapies. Multivariate logistic regression models were used to assess predictors of polypharmacy across residents and LTC homes.ResultsNine or more drug therapies were dispensed concurrently to 10,007 (15.5%) of LTC home residents. Compared with those dispensed fewer drugs, residents receiving 9 or more drug therapies were more likely to have multiple comorbidities. There was threefold variation in polypharmacy rates across homes (26.2% versus 7.9%) and facility-level rates of polypharmacy were modestly correlated with rates of use of Beers criteria drugs (r = 0.27, P < .001) and antipsychotic drug therapies (r = 0.16, P < .001). Controlling for resident factors, those living in LTC homes with high polypharmacy rates were more likely to receive 9 or more drug therapies (odds ratio 1.9, 95% confidence interval 1.7–2.0).ConclusionResidents in Ontario LTC homes commonly received nine or more concurrent drug therapies, particularly residents with multiple chronic conditions. The threefold variation in rate across homes suggests a role for this measure in guiding drug review at the facility level.     

Efficacy and Generalizability of Falls Prevention Interventions in Nursing Homes: A Systematic Review and Meta-analysis

ObjectivesTo determine the efficacy of fall intervention programs in nursing homes (NHs) and the generalizability of these interventions to people living with cognitive impairment and dementia.DesignSystematic review and meta-analysis.Setting and ParticipantsNH residents (n = 30,057) living in NHs defined as residential facilities that provide 24-hours-a-day surveillance, personal care, and some clinical care for persons who are typically aged ≥65 years with multiple complex chronic health conditions.MethodsMeta-analysis of falls prevention interventions on number of falls, fallers, and recurrent fallers.ResultsThirty-six studies met inclusion criteria for the systematic review. Overall, fall prevention interventions reduced the number of falls [risk ratio (RR) = 0.73, 95% confidence interval (CI) = 0.60-0.88], fallers (RR = 0.80, 95% CI = 0.72-0.89), and recurrent fallers (RR = 0.70, 95% CI = 0.60-0.81). Subanalyses revealed that single interventions have a significant effect on reducing fallers (RR = 0.78, 95% CI = 0.69-0.89) and recurrent fallers (RR = 0.60, 95% CI = 0.52-0.70), whereas multiple interventions reduce fallers (RR = 0.69, 95% CI = 0.39-0.97) and multifactorial interventions reduce number of falls (RR = 0.65, 95% CI = 0.45-0.94).Conclusions and ImplicationsExercise as a single intervention reduced the number of fallers and recurrent fallers by 36% and 41%, respectively, in people living in NHs. Other effective interventions included staff education and multiple and multifactorial interventions. However, more research on exercise including people with cognitive impairment and dementia is needed to improve the generalizability of these interventions to the typical NH resident.     

Efecto de una intervención multidimensional en personas mayores autovalentes para el manejo del riesgo de caídas

ObjectiveTo evaluate the effect of a multidimensional intervention on the perception and management of risk factors and frequency of falls in independent elderly people living in the community.DesignRandomised clinical trial.SettingFamily health centre, primary care.ParticipantsIndependent elderly people living in the community.InterventionFor intervention group (IG) a multidimensional intervention, consisting of home visits and telephone follow-up was carried out for 5 months (n = 77), and those assigned to the control group (CG, n = 77) received usual care in the family health centre.Main measurementsPerception of risk of falls, number of risk factors and number of falls in the study period.ResultsIn both groups there were increases in the perception of risk factors for falling associated with walking (IG: P < .001 and CG: P < .001). Belonging to the IG was significantly associated with a decrease in the risk factors associated with surfaces (r = 0.25) and shoes (r = 0.24), as well as an increase in the perception of risk of falls associated with walking (r = 0.21) and the presence of objects or furniture (r = 0.36). In the IG, 5 participants (7.9%) suffered at least one fall in the 5-month period and 18 (27.7%) patients in the CG (P = .004).ConclusionsThe multidimensional intervention was effective in reducing the frequency of falls and in the management of extrinsic risk factors associated with surfaces, lighting, and support devices.     

Impact of Atrial Fibrillation on Falls in Older Patients: Which is a Problem,Existence or Persistence?

ObjectivesSeveral studies have suggested a possible relationship between atrial fibrillation (AF) and falls. However, whether the relationship depends on AF types is unclear. We investigated the relationship between sustaining AF and falls.DesignSingle hospital-based cohort study with a follow-up of falls within 3 years after baseline.Setting and ParticipantsA total of 14,056 patients from our cohort between February 2010 and March 2016.MeasuresIncidence of falls within 3 years by baseline cardiac rhythm was measured, and we investigated the effects of AF types on incidence of falls.ResultsThe study population was divided into younger (<75 years old; n = 11,808) and older (≥75 years old; n = 2248) groups, and then divided into 3 groups according to the baseline cardiac rhythm: sinus rhythm (SR), paroxysmal AF (PAF), and persistent AF (PeAF). There were more male patients in the PeAF group; these patients had more comorbidities both in the younger and older groups. The cumulative incidence rates of falls at 1 year in patients with SR, PAF, and PeAF were similar in the younger group (0.4%, 0.4%, and 0.6%, respectively; P = .496), whereas those were significantly different in the older group (2.3%, 2.7%, and 5.0%, respectively; P = .024). In multivariate analysis, both PAF [hazard ratio (HR) 1.179; 95% confidence interval (CI) 0.553–2.511, reference SR] and PeAF (HR 1.502; 95% CI 0.635–3.556) were not associated with falls in the younger group. In the older group, PeAF was independently associated with incidence of falls (HR 2.257; 95% CI 1.262–4.037), but PAF was not (HR 1.317; 95% CI 0.673–2.574).Conclusions/ImplicationsPeAF, not PAF, was associated independently with falls in older patients, suggesting the possible effect of irregular beats on physical frailty in the older population.
