Variations over time in the effects of age and sex on hospitalization rates before and after admission to a nursing home: A German cohort study

Differences in emergency department visits and hospitalization between German and Dutch nursing home residents: a cross-national survey

PURPOSE

Assessing and comparing German and Dutch nursing home perspectives on residents' hospital transfers.

METHODS

Cross-sectional study among German and Dutch nursing homes. Two surveys were conducted in May 2022, each among 600 randomly selected nursing homes in Germany and the Netherlands. The questionnaires were identical for both countries. The responses were compared between the German and Dutch participants.

RESULTS

We received 199 German (response: 33.2%) and 102 Dutch questionnaires (response: 17.0%). German nursing homes estimated the proportion of transfers to hospital during 1 year to be higher than in Dutch facilities (emergency department visits: 26.5% vs. 7.9%, p < 0.0001; hospital admissions: 29.5% vs. 10.5%, p < 0.0001). In German nursing homes, the proportion of transfers to hospital where the decision was made by the referring physician was lower than in the Dutch facilities (58.8% vs. 88.8%, p < 0.0001). More German nursing homes agreed that nursing home residents are transferred to the hospital too frequently (24.5% vs. 10.8%, p = 0.0069). German nursing homes were much more likely than Dutch facilities to believe that there was no alternative to transfer to a hospital when a nursing home resident had a fall (66.3% vs. 12.8%, p < 0.0001).

CONCLUSION

German nursing home residents are transferred to hospital more frequently than Dutch residents. This can probably be explained by differences in the care provided in the facilities. Future studies should, therefore, look more closely at these two systems and examine the extent to which more intensive outpatient care can avoid transfers to hospital.

Predictors of mortality shortly after entering a long-term care facility

OBJECTIVE

Moving into a long-term care facility (LTCF) requires substantial personal, societal and financial investment. Identifying those at high risk of short-term mortality after LTCF entry can help with care planning and risk factor management. This study aimed to: (i) examine individual-, facility-, medication-, system- and healthcare-related predictors for 90-day mortality at entry into an LTCF and (ii) create risk profiles for this outcome.

DESIGN

Retrospective cohort study using data from the Registry of Senior Australians.

SUBJECTS

Individuals aged ≥ 65 years old with first-time permanent entry into an LTCF in three Australian states between 01 January 2013 and 31 December 2016.

METHODS

A prediction model for 90-day mortality was developed using Cox regression with the purposeful variable selection approach. Individual-, medication-, system- and healthcare-related factors known at entry into an LTCF were examined as predictors. Harrell's C-index assessed the predictive ability of our risk models.

RESULTS

116,192 individuals who entered 1,967 facilities, of which 9.4% (N = 10,910) died within 90 days, were studied. We identified 51 predictors of mortality, five of which were effect modifiers. The strongest predictors included activities of daily living category (hazard ratio [HR] = 5.41, 95% confidence interval [CI] = 4.99-5.88 for high vs low), high level of complex health conditions (HR = 1.67, 95% CI = 1.58-1.77 for high vs low), several medication classes and male sex (HR = 1.59, 95% CI = 1.53-1.65). The model out-of-sample Harrell's C-index was 0.773.

CONCLUSIONS

Our mortality prediction model, which includes several strongly associated factors, can moderately well identify individuals at high risk of mortality upon LTCF entry.

Hospitalisations before and after entry into a residential aged care facility: An interrupted time series analysis

OBJECTIVE

Hospitalisations are an important indicator of safety and quality of care in residential aged care facilities (RACFs). This study aimed to investigate changes in hospital use 12 months before and 12 months after RACF entry using routinely collected data from 25 Australian RACFs.

METHODS

This was a retrospective longitudinal cohort study using linked aged care provider and hospital record data. The sample comprised 1029 residents living in an aged care facility between July 2014 and December 2019 who had stayed a minimum of 12 months in an RACF. The outcome measures were all-cause hospitalisations and fall-related hospitalisations. We applied an interrupted time series analysis using segmented regression to examine changes in both outcome measures over time. Stratified analyses were conducted by gender and dementia status.

RESULTS

The rate of all-cause hospitalisations increased dramatically over the 12 months before RACF entry, from 97 per 1000 residents per month 12 months prior to RACF admission to 303 per 1000 residents at the second month prior to RACF entry. All-cause hospitalisations then decreased considerably to 55 per 1000 residents upon RACF admission and stabilised across the next 12 months. Such trajectories were also observed in fall-related hospitalisations and were consistent for gender and dementia status.

CONCLUSIONS

In this study, hospitalisation rates decreased significantly after RACF entry, and such reductions were maintained for residents who stayed for 12 months in RACFs. Multiple hospital admissions are likely to precipitate entry into RACF. Additional investigation of how community-based services can be successful in reducing the escalating hospitalisations is needed.

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.

[Impact of CoCare, a Complex Model Intervention, on medical care in long-term care nursing homes in Germany: An overview of the outcome and process evaluation]

INTRODUCTION

More and more people are being cared for in nursing homes these days. Multimorbidity results in frequent but sometimes unnecessary patient transports and hospitalisations. The CoCare intervention was developed as a nursing home-based intervention to improve coordination of medical care and GP and specialist care in long-term care homes. The project aimed to reduce avoidable hospital admissions and ambulance transportation, minimise costs through the resulting better collaboration and improving the quality of life of nursing home residents. This article presents the results of the process and outcome evaluation of the intervention in an integrated way and assesses them against the background of the project objectives.

METHODS

Intervention and data collection started in January 2018 and ended in September 2020. A mixed-methods design was chosen for the evaluation. The (cost) effectiveness of the intervention was tested by a controlled observational study, comparing intervention (IG) and control group (CG). As part of the evaluation of the results, claims data from health insurance funds and a questionnaire-based survey among nursing staff, physicians and nursing home residents were analysed. As part of the process evaluation, subjectively perceived changes in care and implementation difficulties were recorded with the help of focus groups and telephone interviews conducted quarterly.

RESULTS

From the point of view of the health economic evaluation, with a decrease in total costs of € 468.56 (p<.001) per nursing home resident and quarter, an advantageous cost-benefit ratio can be assumed. Thus, the significant increase in outpatient care for nursing home residents goes along with a reduction of ambulance transportation by 0.19 (p=.049) and hospitalization rates by 0.08 (p=.001). In the nursing staff sample, a significant positive difference between IG (T1) and CG was observed with regard to communication and cooperation. In addition, pre-post comparison showed a significant improvement in the nursing staff's assessment of interprofessional cooperation in IG at T1 compared to T0. Both nursing staff and physicians perceived positive changes in care and positively assessed the benefit of the intervention. While practitioners experienced an intensification and improvement of communication and cooperation through the implementation of the CoCare measures, these changes were not perceived by residents.

DISCUSSION

The CoCare intervention lowered the barriers for nursing homes to contact general practitioners, specifically in unclear situations and can thus be seen as an effective tool to reduce potentially avoidable hospital admissions and costs. It is conceivable that results can be transferred to other regions in Germany and to similar care scenarios. It should be examined to what extent approaches of this new form of care can be transferred to standard care and whether adjustments to facilitate the implementation of coordinated care approaches across occupational groups in inpatient care facilities can be proposed within the framework of legislative procedures.

Sex differences in the efficacy and safety of SARS-CoV-2 vaccination in residents of long-term care facilities: insights from the GeroCovid Vax study

Despite the reported sex-related variations in the immune response to vaccination, whether the effects of SARS-CoV-2 vaccination differ by sex is still under debate, especially considering old vulnerable individuals, such as long-term care facilities (LTCFs) residents. This study aimed to evaluate COVID-19 infections, adverse events, and humoral response after vaccination in a sample of LTCF residents. A total of 3259 LTCF residents (71% females; mean age: 83.4 ± 9.2 years) were enrolled in the Italian-based multicenter GeroCovid Vax study. We recorded the adverse effects occurring during the 7 days after vaccine doses and COVID-19 cases over 12 months post-vaccination. In a subsample of 524 residents (69% females), pre- and post-vaccination SARS-CoV-2 trimeric S immunoglobulin G (Anti-S-IgG) were measured through chemiluminescent assays at different time points. Only 12.1% of vaccinated residents got COVID-19 during the follow-up, without any sex differences. Female residents were more likely to have local adverse effects after the first dose (13.3% vs. 10.2%, p = 0.018). No other sex differences in systemic adverse effects and for the following doses were recorded, as well as in anti-S-IgG titer over time. Among the factors modifying the 12-month anti-S-IgG titers, mobility limitations and depressive disorder were more likely to be associated with higher and lower levels in the antibody response, respectively; a significantly lower antibody titer was observed in males with cardiovascular diseases and in females with diabetes or cognitive disorders. The study suggests that, among LTCF residents, SARS-CoV-2 vaccination was effective regardless of sex, yet sex-specific comorbidities influenced the antibody response. Local adverse reactions were more common in females.

Hospitalization of German and Dutch Nursing Home Residents Depend on Different Long-Term Care Structures: A Systematic Review on Periods of Increased Vulnerability

OBJECTIVE

To investigate proportions of hospitalized nursing home residents during periods of increased vulnerability, ie, the first 6 months after institutionalization and the last 6 months before death, and comparing the figures between Germany and the Netherlands.

DESIGN

Systematic review, registered in PROSPERO (CRD42022312506).

SETTING AND PARTICIPANTS

Newly admitted or deceased residents.

METHODS

We searched MEDLINE via PubMed, EMBASE, and CINAHL from inception through May 3, 2022. We included all observational studies that reported the proportions of all-cause hospitalizations among German or Dutch nursing home residents during these defined vulnerable periods. Study quality was assessed using the Joanna Briggs Institute's tool. We assessed study and resident characteristics and outcome information and descriptively reported them separately for both countries.

RESULTS

We screened 1856 records for eligibility and included 9 studies published in 14 articles (Germany: 8; Netherlands: 6). One study for each country investigated the first 6 months after institutionalization. A total of 10.2% of the Dutch and 42.0% of the German nursing home residents were hospitalized during this time. Overall, 7 studies reported on in-hospital deaths, with proportions ranging from 28.9% to 29.5% for Germany and from 1.0% to 16.3% for the Netherlands. Proportions for hospitalization in the last 30 days of life ranged from 8.0% to 15.7% (Netherlands: n = 2) and from 48.6% to 58.0% (Germany: n = 3). Only German studies assessed the differences by age and sex. Although hospitalizations were less common at older ages, they were more frequent in male residents.

CONCLUSIONS AND IMPLICATIONS

During the observed periods, the proportion of nursing homes residents being hospitalized differed greatly between Germany and the Netherlands. The higher figures for Germany can probably be explained by differences in the long-term care systems. There is a lack of research, especially for the first months after institutionalization, and future studies should examine the care processes of nursing home residents following acute events in more detail.

Predictors of hospitalisations and emergency department presentations shortly after entering a residential aged care facility in Australia: a retrospective cohort study

OBJECTIVES

To: (1) examine the 90-day incidence of unplanned hospitalisation and emergency department (ED) presentations after residential aged care facility (RACF) entry, (2) examine individual-related, facility-related, medication-related, system-related and healthcare-related predictors of these outcomes and (3) create individual risk profiles.

DESIGN

Retrospective cohort study using the Registry of Senior Australians. Fine-Gray models estimated subdistribution HRs and 95% CIs. Harrell's C-index assessed risk models' predictive ability.

SETTING AND PARTICIPANTS

Individuals aged ≥65 years old entering a RACF as permanent residents in three Australian states between 1 January 2013 and 31 December 2016 (N=116 192 individuals in 1967 RACFs).

PREDICTORS EXAMINED

Individual-related, facility-related, medication-related, system and healthcare-related predictors ascertained at assessments or within 90 days, 6 months or 1 year prior to RACF entry.

OUTCOME MEASURES

90-day unplanned hospitalisation and ED presentation post-RACF entry.

RESULTS

The cohort median age was 85 years old (IQR 80-89), 62% (N=71 861) were women, and 50.5% (N=58 714) had dementia. The 90-day incidence of unplanned hospitalisations was 18.0% (N=20 919) and 22.6% (N=26 242) had ED presentations. There were 34 predictors of unplanned hospitalisations and 34 predictors of ED presentations identified, 27 common to both outcomes and 7 were unique to each. The hospitalisation and ED presentation models out-of-sample Harrell's C-index was 0.664 (95% CI 0.657 to 0.672) and 0.655 (95% CI 0.648 to 0.662), respectively. Some common predictors of high risk of unplanned hospitalisation and ED presentations included: being a man, age, delirium history, higher activity of daily living, behavioural and complex care needs, as well as history, number and recency of healthcare use (including hospital, general practitioners attendances), experience of a high sedative load and several medications.

CONCLUSIONS

Within 90 days of RACF entry, 18.0% of individuals had unplanned hospitalisations and 22.6% had ED presentations. Several predictors, including modifiable factors, were identified at the time of care entry. This is an actionable period for targeting individuals at risk of hospitalisations.

Unplanned hospital transfers from nursing homes: who is involved in the transfer decision? Results from the HOMERN study

Background

Emergency department visits and hospital admissions are common among nursing home residents (NHRs) and seem to be higher in Germany than in other countries. Yet, research on characteristics of transfers and involved persons in the transfer decision is scarce.

Aims

The aim of this study was to analyze the characteristics of hospital transfers from nursing homes (NHs) focused on contacts to physicians, family members and legal guardians prior to a transfer.

Methods

We conducted a multi-center study in 14 NHs in the regions Bremen and Lower Saxony (Northwestern Germany) between March 2018 and July 2019. Hospital transfers were documented for 12 months by nursing staff using a standardized questionnaire. Data were derived from care records and perspectives of nursing staff and were analyzed descriptively.

Results

Among 802 included NHRs, n = 535 unplanned hospital transfers occurred of which 63.1% resulted in an admission. Main reasons were deterioration of health status (e.g. fever, infections, dyspnea and exsiccosis) (35.1%) and falls/accidents/injuries (33.5%). Within 48 h prior to transfer, contact to at least one general practitioner (GP)/specialist/out-of-hour-care physician was 46.2% and varied between the NHs (range: 32.3–83.3%). GPs were involved in only 34.8% of transfer decisions. Relatives and legal guardians were more often informed about transfer (62.3% and 66.8%) than involved in the decision (21.8% and 15.1%).

Discussion

Contacts to physicians and involvement of the GP were low prior to unplanned transfers. The ranges between the NHs may be explained by organizational differences.

Conclusion

Improvements in communication between nursing staff, physicians and others are required to reduce potentially avoidable transfers.

Acute health care services use among nursing home residents in Germany: a comparative analysis of out-of-hours medical care, emergency department visits and acute hospital admissions

BACKGROUND

Nursing home (NH) residents often utilise acute health care services. However, comparative data on those are lacking.

AIMS

Investigating German NH residents' use of out-of-hours medical care (OOHC), visits to emergency departments (EDs) and acute hospital admissions (AHAs).

METHODS

Using claims data of 1665 residents for 2014-2015, we conducted a retrospective cohort study, examining the incidence rates involving the different services. Multivariate Poisson regression analyses were performed to calculate relative risks (RRs). Differences in the utilisations over the days of the week and of the reasons for contacts were assessed.

RESULTS

In total, 3576 contacts occurred (mean age 80.5 years, women 66.3%), resulting in an overall incidence rate of 2.7 per person-year (95% confidence interval 2.6-2.8). Strongest predictors were polypharmacy (RR 1.79; 95% CI 1.50-2.12), followed by male sex and higher care dependency. Among the three services AHAs showed the highest rates. Injuries were the most common reasons for visiting EDs, whereas for OOHC use and AHAs, coded diagnoses covered a broader spectrum. Utilisation of the services on weekdays varied, particularly for OOHC.

DISCUSSION

Polypharmacy, a higher care dependency and male sex seem to play a role in predicting acute health care services. Considering the distribution of the diagnoses of all three types, certain patterns concerning the symptoms' acuity become apparent.

CONCLUSIONS

Our findings revealed high acute health care services use among NH residents in Germany and differences among the three available services. This information can be used to design studies for investigating the appropriateness of these contacts.

Health and care service utilisation and cost over the life-span: a descriptive analysis of population data

BACKGROUND

Current demographic changes affect both the level and composition of health and care needs in the population. The aim of this study was to estimate utilisation and cost for a comprehensive range of health and care services by age and gender to provide an in-depth picture of the life-span pattern of service needs and related costs.

METHODS

Data on service use in 2010 for the entire population in Norway were collected from four high-quality national registers. Cost for different services were calculated combining data on service utilisation from the registries and estimates of unit cost. Data on cost and users were aggregated within four healthcare services and seven long-term care services subtypes. Per capita cost by age and gender was decomposed into user rates and cost per user for each of the eleven services.

RESULTS

Half of the population is under 40 years of age, but only a quarter of the health and care cost is used on this age group. The age-group of 65 or older, on the other hand, represent only 15% of the population, but is responsible for almost half of the total cost. Healthcare cost dominates in ages under 80 and mental health services dominates in adolescents and young adults. Use of other healthcare services are high in middle aged and elderly but decreases for the oldest old. Use of care services and in particular institutional care increases in old age. Healthcare cost per user follows roughly the same age pattern as user rates, whereas user cost for care services typically are either relatively stable or decrease with age among adults. Gender differences in the age pattern of health and care costs are also revealed and discussed.

CONCLUSION

The type of services used, and the related cost, show a clear life-span as well as gender pattern. Hence, population aging and narrowing gender-gap in longivety calls for high policy awarness on changing health and care needs. Our study also underscores the need for an attentive and pro-active stance towards the high service prevalence and high cost of mental health care in our upcoming generations.

Malnutrition is associated with increased risk of hospital admission and death in the first 18 months of institutionalization

OBJECTIVES

This study aimed to investigate the association between different nutritional and anthropometric parameters with the risk of hospitalizations and death within 18 months from nursing home admission. Our hypothesis was that measures of malnutrition could be more strongly associated with worse clinical outcomes than measures of overweight/obesity.

METHODS

This prospective study involved 144 older adults newly admitted in nursing home and followed up over 18 months. A multidimensional assessment focusing on clinical, functional and cognitive status was performed at baseline. Assessment also included body mass index (BMI), waist circumference, calf circumference, MNA Short-Form (MNA-SF), and serum albumin and lymphocytes levels. Anthropometric measurements were repeated at 6 months. Data on hospitalizations and mortality over the study period, with their respective causes, were obtained from administrative data. The associations between baseline nutritional parameters and the risk of hospitalizations or death were analyzed through multinomial logistic regressions and Cox regressions, respectively.

RESULTS

During the follow-up, 64 individuals (44.4%) were hospitalized, and 52 (36.1%) died. Residents who reported low MNA-SF and calf circumference at nursing home admission had more than threefold-increased odds of hospitalizations compared with their healthier counterparts. Adults with low calf circumference also had the highest mortality (HR = 3.39, 95%CI:1.80-6.39), while more attenuated results were observed for low serum albumin, MNA-SF, and BMI (either when considering cut-offs of excess weight or malnutrition). When assessing the associations between 0 and 6 month changes in calf circumference and mortality in the following 12 months, we found that each 1 cm decrease in calf circumference increased the one-year mortality by 29% (95%CI 1.04-1.60).

CONCLUSIONS

Malnutrition, but not overweight/obesity, seems associated with a higher risk of hospitalization and mortality after nursing home admission. Monitoring calf circumference, in particular, may help in the early detection of individuals who are potentially vulnerable to adverse health-related outcomes after institutionalization.

[Hospitalization of nursing home residents in the last phase of life: an analysis of health insurance data]

Hintergrund

Im internationalen Vergleich versterben Pflegeheimbewohner in Deutschland häufig im Krankenhaus. Daten zu längeren Zeiträumen vor dem Tod und zu regionalen Unterschieden fehlen.

Ziel der Arbeit

Es werden Häufigkeiten von Krankenhausaufenthalten bei Pflegeheimbewohnern in verschiedenen Perioden vor dem Tod analysiert. Zudem werden Unterschiede nach Alter, Geschlecht, Pflegestufe, Demenz und Bundesländern untersucht.

Material und Methoden

Wir verwendeten Daten einer großen Krankenkasse und schlossen Pflegeheimbewohner im Mindestalter von 65 Jahren ein, die zwischen dem 01.01.2010 und dem 31. 12.2014 verstarben. Outcome war mindestens ein Krankenhausaufenthalt nach Heimeintritt in verschiedenen Phasen des letzten Lebensjahres. Vertiefende Analysen wurden für die Zeiträume 0 (entspricht Versterben im Krankenhaus), 28 und 365 Tage vor Tod durchgeführt.

Ergebnisse

Von den insgesamt 67.328 verstorbenen Bewohnern (mittleres Alter: 85,3 Jahre; 69,8 % weiblich), verstarben 29,5 % im Krankenhaus. In den letzten 28 bzw. 365 Tagen vor Tod hatten 51,5 % bzw. 74,3 % mindestens einen Krankenhausaufenthalt. Diese Werte waren in ostdeutschen Bundesländern höher. In allen Zeiträumen wurden Männer häufiger hospitalisiert. Bewohner mit höherer Pflegestufe wurden seltener stationär behandelt, besonders unmittelbar vor dem Tod. Demenz hatte keinen nennenswerten Einfluss auf die Hospitalisierungshäufigkeiten.

Diskussion

Etwa die Hälfte der Pflegeheimbewohner wird im letzten Lebensmonat stationär behandelt, und ein Drittel verstirbt im Krankenhaus, was, international betrachtet, hoch ist. Dass wir keine Unterschiede bei Bewohnern mit und ohne Demenz fanden, widerspricht ebenso internationalen Befunden. Somit besteht erheblicher Handlungsbedarf, die palliative Versorgung von Pflegeheimbewohnern zu optimieren.

Ten-year trends in end-of-life hospitalizations of nursing home residents in Germany, 2006-2015

OBJECTIVES

We investigated trends in end-of-life hospitalizations among nursing home residents (NHR) over 10 years and looked at differences between age groups and sexes as well as the length of terminal hospital stays.

STUDY DESIGN

Retrospective cohort study based on health insurance claims data of the AOK Bremen/Bremerhaven. All NHR aged 65 years or more who died between 2006 and 2015 were included.

MAIN OUTCOME MEASURES

We assessed the proportions of decedents who were in hospital on the day of death and during the last 3, 7, 14 and 30 days of life, stratified by two-year periods. Multiple logistic regressions were conducted to study changes over time, adjusting for covariates.

RESULTS

A total of 10,781 decedents were included (mean age 86.1 years, 72.1 % females). Overall, 29.2 % died in hospital, with a slight decrease from 30.3 % in 2006-2007 to 28.3 % in 2014-2015 (OR 0.86; 95 % CI 0.75-0.98). Of the 3150 terminal hospitalizations, 35.5 % lasted up to 3 days and the mean length of stay decreased from 9.0 (2006-2007) to 7.5 days (2014-2015). When looking at the last 7, 14 and 30 days of life, no changes over time were found. Male sex and younger age were associated with a higher chance of end-of-life hospitalization in almost all analyses.

CONCLUSIONS

End-of-life hospitalizations of NHR are common in Germany. There has been a small decrease during recent years in the proportion of in-hospital deaths, but not of hospitalizations during the last 7, 14 and 30 days of life. This might be explained by shorter durations of hospital stays.

Perspectives of general practitioners and nursing staff on acute hospital transfers of nursing home residents in Germany: results of two cross-sectional studies

Background

Visits in emergency departments and hospital admissions are common among nursing home (NH) residents and they are associated with significant complications. Many of these transfers are considered inappropriate. This study aimed to compare the perceptions of general practitioners (GPs) and NH staff on hospital transfers among residents and to illustrate measures for improvement.

Methods

Two cross-sectional studies were conducted as surveys among 1121 GPs in the German federal states Bremen and Lower Saxony and staff from 1069 NHs (preferably nursing staff managers) from all over Germany, each randomly selected. Questionnaires were sent in August 2018 and January 2019, respectively. The answers were compared between GPs and NH staff using descriptive statistics, Mann-Whitney U tests and χ2-tests.

Results

We received 375 GP questionnaires (response: 34%) and 486 NH questionnaires (response: 45%). GPs estimated the proportion of inappropriate transfers higher than NH staff (hospital admissions: 35.0% vs. 25.6%, p < 0.0001; emergency department visits: 39.9% vs. 20.9%, p < 0.0001). The majority of NH staff and nearly half of the GPs agreed that NH residents do often not benefit from hospital admissions (NHs: 61.4% vs. GPs: 48.8%; p = 0.0009). Both groups rated almost all potential measures for improvement differently (p < 0.0001), however, GPs and NH staff considered most areas to reduce hospital transfers importantly. The two most important measures for GPs were more nursing staff (91.6%) and better communication between nursing staff and GP (90.9%). NH staff considered better care / availability of GP (82.8%) and medical specialists (81.3%) as most important. Both groups rated similarly the importance of explicit advance directives (GPs: 77.2%, NHs: 72.4%; p = 0.1492).

Conclusions

A substantial proportion of hospital transfers from NHs were considered inappropriate. Partly, the ratings of possible areas for improvement differed between GPs and NH staff indicating that both groups seem to pass the responsibility to each other. These findings, however, support the need for interprofessional collaboration.

Dying in hospital among nursing home residents with and without dementia in Germany

OBJECTIVES

Nursing home residents (NHR) often suffer from dementia. As end-of-life care of NHR with dementia and without might differ, our aim was to investigate patterns of in-hospital deaths in NHR with and without dementia.

DESIGN

Retrospective observational study.

SETTING

German nursing homes.

PARTICIPANTS

Deceased NHR.

MEASUREMENTS

Using data of a large German health insurance fund, we included NHR aged 65+ years who died between January 1, 2010, and December 31, 2014. We assessed proportions of in-hospital deaths stratified by dementia status as well as by age, sex, level of care and length of stay. Multiple logistic regression models were applied to explore the association of these variables with in-hospital death.

RESULTS

Data on 67,328 decedents were included (mean age 85.3 years, 69.8% female), of whom 43.1% suffered from dementia. Overall, 29.5% died in hospital, with similar figures found for those with dementia (29.2%) and those without (29.8%). Differences between NHR with and without dementia were noticeable regarding age and length of stay. In those with dementia, the proportion of in-hospital deaths decreased linearly with age from 37.0%-20.2% (65-74 to 95+ years). These results are supported by the multivariate analyses. The terminal hospital stay was up to 3 days in 32.6%. This length did not differ by dementia status.

CONCLUSIONS

Germany has a high proportion of NHR in-hospital deaths. Surprisingly, we found no differences in these figures between NHR with and without dementia, although predictors for in-hospital death seem to differ between these groups.

Age and sex differences in emergency department visits of nursing home residents: a systematic review

Background

Nursing home residents (NHRs) are often transferred to emergency departments (EDs). A great proportion of ED visits is considered inappropriate. There is evidence that male NHRs are more often hospitalised, but this is less clear for ED visits. It is unclear, which influence age has on ED visits. We aimed to study the epidemiology of ED visits in NHRs focusing on age- and sex-specific differences.

Methods

A systematic review was carried out based on articles found in MEDLINE (via PubMed), CINAHL and Scopus. Articles published on or before Aug 31, 2017 were eligible. Two reviewers independently identified articles for inclusion. The quality of studies was assessed by the Joanna Briggs Institute critical appraisal tool for prevalence studies.

Results

Out of 1192 references, we found seven studies meeting our inclusion criteria. Six studies were conducted in the USA or Canada. Overall, 29–62% of NHRs had at least one ED visit over the course of 1 year. Most studies assessing the influence of sex found that male residents visited EDs more frequently. All but one of the five studies with multivariable analyses reported a statistically significant positive association (with odds or rate ratios of 1.05–1.38). All studies assessed the influence of age. There was no clear pattern with some studies showing no association between ED visits and age and other studies reporting decreasing ED visits with increasing age or increasing proportions followed by a decrease in the highest age group. Studies used 85+ or 86+ years as the highest age category. Hospital admission rate ranged from 36.4 to 48.7%. There was no study reporting stratified analyses by age and sex. Only one study reported main diagnoses leading to ED visits stratified by sex.

Conclusion

Male NHRs visit EDs more often than females, but there is no evidence on reasons. The association with age is unclear. Any future study on acute care of NHRs should assess the influence of age and sex. These studies should include large sample sizes to provide a more differentiated age categorisation.

Incidence of pneumonia in nursing home residents in Germany: results of a claims data analysis

Pneumonia is one of the most common infectious diseases with a high mortality, especially in the elderly population. To date, there have been only a few population-based studies dealing with the incidence of pneumonia in nursing homes (NHs). We conducted a cohort study using data from a large German statutory health insurance fund. Between 2010 and 2014, 127 227 NH residents 65 years and older were analysed. For the calculation of incidences per 100 person-years (PY) and 95% confidence intervals (CIs), we assessed the first diagnosis of pneumonia during the time in NH. We compared the rates between sexes, age groups, care levels, and comorbidities and we performed a multivariate Cox regression analysis. The mean age in the cohort was 84.0 years (74.6% female). A total of 19 183 incident cases led to an overall 5-year-incidence of 11.8 per 100 PY (95% CI 11.7-12.0). The incidence in men was substantially higher than in women. Rates were highest in the first month after NH placement. Our study revealed that the incidence of pneumonia is high in German NH residents and especially in males. Due to demographic changes, pneumonia will likely be increasingly relevant in the health care of the elderly and institutionalised population.
