Impact of a complex health services intervention in long-term care nursing homes on 3-year overall survival: results from the CoCare study.

BACKGROUND: The Coordinated medical Care (CoCare) project aimed to improve the quality of medical care in nursing homes by optimizing collaboration between nurses and physicians. We analyze the impact of the CoCare intervention on overall survival. METHODS: The effect of time-varying treatment on 3-year overall survival was analyzed with treatment as time-varying covariate within the entire cohort. To reduce bias due to non-random assignment to treatment groups, regression adjustment was applied. Therefore, age, sex, and level of care were used as potential confounders. RESULTS: The study population consisted of 8,893 nursing home residents (NHRs), of which 1,330 participated in the CoCare intervention. The three-year overall survival was 49.8% in the entire cohort. NHRs receiving the intervention were associated with a higher survival probability compared to NHRs of the control group. In a univariable cox model with time-dependent treatment, the intervention was associated with a hazard ratio of 0.70 [95%CI 0.56-0.87, p = 0.002]. After adjustment for age, sex and level of care, the hazard ratio increased to 0.82 but was still significant [95%CI 0.71-0.96, p = 0.011]. CONCLUSION: The analysis shows that optimizing collaboration between nurses and physicians leads to better survival of NHRs in Germany. This adds to the already published favorable cost-benefit ratio of the CoCare intervention and shows that a routine implementation of optimized collaboration between nurses and physicians is highly recommended.

[Facilitating Interprofessional Collaboration in Nursing Homes: Effects of a Complex Model Intervention (CoCare) to Improve On-Site Medical Care. Results of a Controlled Study with Pre-Post Measurement]. / Können die Maßnahmen der komplexen Modellintervention CoCare die Zusammenarbeit von Pflegekräften und Ärzt*innen in Pflegeheimen verbessern? Ergebnisse einer kontrollierten Studie mit Prä-Post-Messung.

AIM: The model project "CoCare - Extended coordinated medical care in long-term care homes" (funding: Innovation Committee of the Federal Joint Committee) aspired to improve on-site medical care in nursing homes by introducing a new form of care. Participating nursing homes implemented a number of intervention elements designed to facilitate interprofessional collaboration. We surveyed nursing staff and attending physicians as part of the project's summative evaluation. METHODS: The intervention group (IG) participated in our survey once before the implementation of the intervention (T0) as well as 12 months after implementation had started (T1). The control group (CG), in which residents received usual treatment ("usual care"), completed one survey. We investigated whether IG participants rated interprofessional collaboration more positively after the intervention, and attempted to detect advantages in their assessment at T1 as compared to the CG. Additionally, we analyzed if IG participants perceived improvements in on-site medical care from T0 to T1 and to what extent they evaluated the intervention and its components as beneficial. RESULTS: N=836 participants (678 nursing staff and 158 physicians) took part in the surveys. IG nursing staff demonstrated significant improvements in assessment of interprofessional collaboration from T0 to T1, while we found only partially significant improvements among IG physicians. Additionally, IG nursing staff rated interprofessional collaboration significantly better at T1 as compared to the CG. No such differences were found in the physician sample. Both nursing staff and physicians in the IG indicated significant improvements in on-site medical care after the intervention was implemented. They rated the overall intervention as overwhelmingly beneficial. Both professions found the regularly scheduled, weekly ward rounds and the appointment of fixed contact points particularly valuable. CONCLUSION: The implementation of the "CoCare" measures can improve nursing staff's and physicians' assessments of interprofessional collaboration and on-site medical care. However, participation in the survey was limited, especially among physicians, which reduced the statistical power of calculations.

Reduction of care-relevant risks to older patients during and after acute hospital care (ReduRisk) - study protocol of a cluster randomized efficacy trial in a stepped wedge design.

BACKGROUND: Older patients are at an increased risk of hospitalization, negatively affecting their health and quality of life. Such patients also experience a lack of physical activity during their inpatient stay, as well as being at increased risk of delirium and inappropriate prescribing. These risk factors can accumulate, promoting a degree of morbidity and the development of cognitive impairment. METHODS: Through the ReduRisk-program, patients at risk of functional impairment, immobility, falls, delirium or re-hospitalization shortly after hospital discharge, will be identified via risk-screening. These patients will receive an individually tailored, multicomponent and risk-adjusted prevention program. The trial will compare the effectiveness of the ReduRisk-program against usual care in a stepped-wedge-design, with quarterly cluster randomization of six university hospital departments into intervention and control groups. 612 older adults aged 70 years or more are being recruited. Patients in the intervention cluster (n = 357) will receive the ReduRisk-program, comprising risk-adjusted delirium management, structured mobility training and digitally supported planning of post-inpatient care, including polypharmacy management. This study will evaluate the impact of the ReduRisk-program on the primary outcomes of activities of daily living and mobility, and the secondary outcomes of delirium, cognition, falls, grip strength, health-related quality of life, potentially inappropriate prescribing, health care costs and re-hospitalizations. Assessments will be conducted at inpatient admission (t0), at discharge (t1) and at six months post-discharge (t2). In the six-month period following discharge, a health-economic evaluation will be carried out based on routine health insurance data (t3). DISCUSSION: Despite the importance of multicomponent, risk-specific approaches to managing older patients, guidelines on their effectiveness are lacking. This trial will seek to provide evidence for the effectiveness of a multicomponent, risk-adjusted prevention program for older patients at risk of functional impairment, immobility, falls, delirium and re-hospitalization. Positive study results would support efforts to improve multicomponent prevention and the management of older patients.

Barriers and facilitators for implementation of a complex health services intervention in long-term care homes: a qualitative study using focus groups.

BACKGROUND: With rising numbers of elderly people living in nursing homes in Germany, the need for on-site primary care is increasing. A lack of primary care in nursing homes can lead to unnecessary hospitalization, higher mortality, and morbidity in the elderly. The project CoCare ("coordinated medical care") has therefore implemented a complex health intervention in nursing homes, using inter alia, regular medical rounds, a shared patient medical record and medication checks, with the aim of improving the coordination of medical care. This study reports upon the results of a qualitative study assessing the perceived barriers and facilitators of the implementation of CoCare by stakeholders. METHODS: Focus group interviews were held between October 2018 and November 2019 with nurses, general practitioners and GP's assistants working or consulting in a participating nursing home. A semi-structured modular guideline was used to ask participants for their opinion on different aspects of CoCare and which barriers and facilitators they perceived. Focus groups were analyzed using qualitative content analysis. RESULTS: In total, N = 11 focus group interviews with N = 74 participants were conducted. We found six themes describing barriers and facilitators in respect of the implementation of CoCare: understaffing, bureaucracy, complexity, structural barriers, financial compensation, communication and collaboration. Furthermore, participants described the incorporation of the intervention into standard care. CONCLUSION: Barriers perceived by stakeholders are well known in the literature (e.g. understaffing and complexity). However, CoCare provides a good structure to overcome barriers and some barriers will dissolve after implementation into routine care (e.g. bureaucracy). In contrast, especially communication and collaboration were perceived as facilitators in CoCare, with the project being received as a team building intervention itself.

A complex health services intervention to improve medical care in long-term care homes: study protocol of the controlled coordinated medical care (CoCare) study.

BACKGROUND: Deficits in general and specialized on-site medical care are a common problem in nursing homes and can lead to unnecessary, costly and burdensome hospitalizations for residents. Reasons for this are often organizational obstacles (such as lack of infrastructure or communication channels) and unfavorable compensation structures, which impede the implementation of adequate medical care. The purpose of this study is to evaluate a complex intervention aiming to improve the coordination of medical care in long-term care nursing homes in Germany. The project aims to optimize the collaboration of nurses and physicians in order to reduce avoidable hospital admissions and ambulance transportations. METHODS/DESIGN: In a prospective controlled trial, nursing home residents receiving a complex on-site intervention are compared to residents receiving care/treatment as usual. The study will include a total of around 4000 residents in approximately 80 nursing homes split equally between the intervention group and the control group. Recruitment will take place in all administrative districts of Baden-Wuerttemberg, Germany. The control group focuses on the administrative district of Tuebingen. The intervention includes on-site visits by physicians joined by nursing staff, the formation of teams of physicians, a computerized documentation system (CoCare Cockpit), joint trainings and audits, the introduction of structured treatment paths and after-hours availability of medical care. The project evaluation will be comprised of both a formative process evaluation and a summative evaluation. DISCUSSION: This study will provide evidence regarding the efficacy of a complex intervention to positively influence the quality of medical care and supply efficiency as well as provide cost-saving effects. Its feasibility will be evaluated in a controlled inter-regional design. TRIAL REGISTRATION: WHO UTN: U1111-1196-6611 ; DRKS-ID: DRKS00012703 (Date of Registration in DRKS: 2017/08/23).

Accelerometry and physical activity questionnaires - a systematic review.

BACKGROUND: The aim of this study is to review accelerometer wear methods and correlations between accelerometry and physical activity questionnaire data, depending on participant characteristics. METHODS: We included 57 articles about physical activity measurement by accelerometry and questionnaires. Criteria were to have at least 100 participants of at least 18 years of age with manuscripts available in English. Accelerometer wear methods were compared. Spearman and Pearson correlation coefficients between questionnaires and accelerometers and differences between genders, age categories, and body mass index (BMI) categories were assessed. RESULTS: In most investigations, requested wear time was seven days during waking hours and devices were mostly attached on hips with waist belts. A minimum of four valid days with wear time of at least ten hours per day was required in most studies. Correlations (r = Pearson, ρ = Spearman) of total questionnaire scores against accelerometer measures across individual studies ranged from r = 0.08 to ρ = 0.58 (P < 0.001) for men and from r = -0.02 to r = 0.49 (P < 0.01) for women. Correlations for total physical activity among participants with ages ≤65 ranged from r = 0.04 to ρ = 0.47 (P < 0.001) and from r = 0.16 (P = 0.02) to r = 0.53 (P < 0.01) among the elderly (≥65 years). Few studies investigated stratification by BMI, with varying cut points and inconsistent results. CONCLUSION: Accelerometers appear to provide slightly more consistent results in relation to self-reported physical activity among men. Nevertheless, due to overall limited consistency, different aspects measured by each method, and differences in the dimensions studied, it is advised that studies use both questionnaires and accelerometers to gain the most complete physical activity information.

Cost-benefit analysis of the CoCare intervention to improve medical care in long-term care nursing homes: an analysis based on claims data.

BACKGROUND: Providing adequate medical care to nursing home residents is challenging. Transfers to emergency departments are frequent, although often avoidable. We conducted the complex CoCare intervention with the aim to optimize nursing staff-physician collaboration to reduce avoidable hospital admissions and ambulance transportations, thereby reducing costs. METHODS: This prospective, non-randomized study, based on German insurance data, includes residents in nursing homes. Health care cost from a payer perspective and cost-savings of such a complex intervention were investigated. The utilisation of services after implementation of the intervention was compared with services in previous quarters as well as services in the control group. To compensate for remaining differences in resident characteristics between intervention and control group, a propensity score was determined and adjusted for in the regression analyses. RESULTS: The study population included 1240 residents in the intervention and 7552 in the control group. Total costs of medical services utilisation were reduced by €468.56 (p < 0.001) per resident and quarter in the intervention group. Hospital stays were reduced by 0.08 (p = 0.001) and patient transports by 0.19 (p = 0.049). This led to 1.66 (p < 0.001) avoided hospital days or €621.37 (p < 0.001) in costs-savings of inpatient services. More services were billed by general practitioners in the intervention group, which led to additional costs of €97.89 (p < 0.001). CONCLUSION: The benefits of our intervention clearly exceed its costs. In the intervention group, avoided hospital admissions led to additional outpatient billing. This indicates that such a multifactorial intervention program can be cost-saving and improve medical care in long-term care homes.

[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]. / Auswirkungen der komplexen Modellintervention CoCare auf die medizinische Versorgung in deutschen Pflegeheimen: eine Übersicht über die Ergebnis- und Prozessevaluation.

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.

Needs assessment towards research data management at the Medical Faculty of the University of Freiburg - Data of the BE-KONFORM study.

In order to investigate employees' needs of the Medical Faculty of the University of Freiburg regarding research data management, the BE-KONFORM study was performed in a two-step approach. First, guideline-based qualitative video interviews with four researchers were performed to identify key constructs of relevance. Second, a standardized online survey was conducted from 1st to 15th of November 2020 based on e-mail invitation by the dean and a faculty newsletter. The questionnaire was provided bilingual (English and German) using a backward-forward translation method, no reminders and incentives were used to increase the response rate. The online survey was programmed in REDCap and was accessible via online link. The target population were members of the Medical Faculty (listed in the newsletter mailing list) regardless of the type of working contract signed. The final dataset contains 236 complete cases (90% German and 10% English). The study includes a randomised module asking for data publication (group A) or not (group B). 113 cases were randomized into group A and 99% of them consented to the publication of the collected research data in anonymized form (n=112). The dataset comprised questions about work-related characteristics (professional status, working experience, scientific field of work), data management-related items (definition of research data management, type of data used, type of storage used for saving data, use of electronic laboratory notebooks), experience and attitudes towards data publication in data repositories, as well as needs and preferences regarding research data management support. The produced data offers the possibility to connect with other data collected in this field in other contexts (faculties or universities).

Sports injuries among adolescents: incidence, causes and consequences.

AIM: The purpose of this study was to evaluate the 1-year incidence, location, type, mechanism and severity of sports injuries for adolescents in Germany. METHODS: Data were from the 'German Health Interview and Examination Survey for Children and Adolescents', a nationwide study of n = 17 641 children and adolescents. Analyses were based on a weighted total sample size of n(w) = 7451 adolescents between 11 and 17 years of age, 51% of them boys. RESULTS: A total of 577 adolescents (8%) reported having experienced a sports injury during the past year. Collisions and falls were reported as being the most important causes. The most frequent diagnoses were contusions, dislocations, strains and sprains (60%), followed by fractures (26%). Most injuries (88%) were treated on an outpatient basis with only 12% resulting in hospitalisation. Gender-specific analyses showed that 9% of the boys and 7% of the girls suffered from a sports injury during the past year. After adjusting for the level of physical activity, these gender differences disappeared (OR(girls) 0.94; 95% confidence intervals: 0.74-1.18). Excluding injuries incurred from falls while horse riding, there were no gender differences in the mechanism of injury. Among boys, 30% of all injuries were fractures, among girls 20% (P < 0.05). Apart from fractures, no further differences between the sexes in the range of diagnoses were identified. CONCLUSIONS: Although these results suggest that the risk of sports injuries does not differ significantly based on adolescents' gender, the incidence rate of adolescent sports injuries within Germany is relatively high.

The association of care satisfaction and COVID-19 contact restrictions with quality of life in long-term care homes residents in Germany: a cross-sectional study.

BACKGROUND: Quality of life (QoL) is a widely recognised outcome in residents of long-term care homes. However, little is known about the impact of care satisfaction on QoL. The aim of this study was to assess the association between care satisfaction and QoL in residents of long-term care homes. Additionally, we were able to assess the impact of the Covid-19 contact restrictions on QoL. METHODS: We applied a cross-sectional study in N = 40 long-term care homes in Baden-Wuerttemberg, Germany. Using regression models, we analysed the association between QoL (operationalised through the World Health Organization Quality of Life Assessment-Old Module [WHOQOL-OLD]) and self-rated nursing care satisfaction. The date on which the questionnaire was completed was used to calculate whether the completion was prior the emergence of the Covid-19 contact restrictions. Further potential confounders were included in the analysis. RESULTS: N = 419 residents of long-term care homes participated. Explained variance of QoL was low in our models at 2 to 16%. Self-rated nursing care satisfaction was the strongest predictor of QoL and positively linked to the following subdimensions of QoL: autonomy; past, present and future activities; social participation; intimacy. The Covid-19 contact restrictions were negatively linked to social participation. CONCLUSION: Nursing care satisfaction was associated with QoL in residents of long-term care homes. Future research should focus on the direction of the association and different aspects of nursing care satisfaction with QoL. Furthermore, we showed the impact of contact restriction during the Covid-19 lockdown on social participation.

Prediction of activity-related energy expenditure under free-living conditions using accelerometer-derived physical activity.

The purpose of the study was to develop prediction models to estimate physical activity (PA)-related energy expenditure (AEE) based on accelerometry and additional variables in free-living adults. In 50 volunteers (20-69 years) PA was determined over 2 weeks using the hip-worn Actigraph GT3X + as vector magnitude (VM) counts/minute. AEE was calculated based on total daily EE (measured by doubly-labeled water), resting EE (indirect calorimetry), and diet-induced thermogenesis. Anthropometry, body composition, blood pressure, heart rate, fitness, sociodemographic and lifestyle factors, PA habits and food intake were assessed. Prediction models were developed by context-grouping of 75 variables, and within-group stepwise selection (stage I). All significant variables were jointly offered for second stepwise regression (stage II). Explained AEE variance was estimated based on variables remaining significant. Alternative scenarios with different availability of groups from stage I were simulated. When all 11 significant variables (selected in stage I) were jointly offered for stage II stepwise selection, the final model explained 70.7% of AEE variance and included VM-counts (33.8%), fat-free mass (26.7%), time in moderate PA + walking (6.4%) and carbohydrate intake (3.9%). Alternative scenarios explained 53.8-72.4% of AEE. In conclusion, accelerometer counts and fat-free mass explained most of variance in AEE. Prediction was further improved by PA information from questionnaires. These results may be used for AEE prediction in studies using accelerometry.

How do nurses and physicians assess inter-professional collaboration in long-term care homes? A survey study.

AIMS: To assess inter-professional collaboration between nurses and physicians in long-term care facilities and to determine if there are differences between subgroups of nurses. DESIGN: A cross-sectional questionnaire survey was carried out between January 2018 and January 2020. METHODS: 408 health professionals (345 nurses, 63 physicians) from 37 nursing homes in Baden-Wuerttemberg (Germany) participated in the survey. For data collection, the "Team-Scale" and "Work Situation Questionnaire for nurses/physicians" instruments were used. Furthermore, five self-generated items were employed assessing how ward rounds and documentation are implemented. For the evaluation, descriptive analyses, one-way variance analyses (ANOVAs) and a multilevel analysis were performed. RESULTS: Inter-professional teamwork was rated positively overall. However, the nursing staff usually gave more critical assessments than the physicians (for example, regarding mutual appreciation). Critical assessments could be used to initiate constructive change processes.

The improved physical activity index for measuring physical activity in EPIC Germany.

In the European Investigation into Cancer and Nutrition study (EPIC), physical activity (PA) has been indexed as a cross-tabulation between PA at work and recreational activity. As the proportion of non-working participants increases, other categorization strategies are needed. Therefore, our aim was to develop a valid PA index for this population, which will also be able to express PA continuously. In the German EPIC centers Potsdam and Heidelberg, a clustered sample of 3,766 participants was re-invited to the study center. 1,615 participants agreed to participate and 1,344 participants were finally included in this study. PA was measured by questionnaires on defined activities and a 7-day combined heart rate and acceleration sensor. In a training sample of 433 participants, the Improved Physical Activity Index (IPAI) was developed. Its performance was evaluated in a validation sample of 911 participants and compared with the Cambridge Index and the Total PA Index. The IPAI consists of items covering five areas including PA at work, sport, cycling, television viewing, and computer use. The correlations of the IPAI with accelerometer counts in the training and validation sample ranged r = 0.40-0.43 and with physical activity energy expenditure (PAEE) r = 0.33-0.40 and were higher than for the Cambridge Index and the Total PA Index previously applied in EPIC. In non-working participants the IPAI showed higher correlations than the Cambridge Index and the Total PA Index, with r = 0.34 for accelerometer counts and r = 0.29 for PAEE. In conclusion, we developed a valid physical activity index which is able to express PA continuously as well as to categorize participants according to their PA level. In populations with increasing rates of non-working people the performance of the IPAI is better than the established indices used in EPIC.
