Effectiveness of food-based fortification in older people a systematic review and meta-analysis

BackgroundEarly intervention with nutritional support has been found to stop weight loss in older people malnourished or at risk of malnutrition. Enriched food could be a more attractive alternative to improve meals, than conventional oral nutritional supplements.AimsTo determine the effectiveness of food-based fortification to prevent risk of malnutrition in elderly patients in community or institutionalized elderly patients.MethodsA systematic review was conducted of randomized controlled trials, quasi-experimental, and interrupted time series including a longitudinal analysis.ParticipantsElderly patients who are institutionalized, hospitalized or community-dwelling, with a minimum average age of 65 years. All type of patient groups, with the exception of people in critical care, or those who were recovering from cancer treatment, were included.InterventionStudies had to compare food-based fortification against alternatives. Studies that used oral nutritional supplementation such as commercial sip feeds, vitamin or mineral supplements were excluded. The search was conducted in Cochrane, CINAHL, PubMed, EMBASE, LILACS, and Cuiden. An independent peer review was carried out.ResultsFrom 1011 studies obtained, 7 were included for the systematic review, with 588 participants. It was possible to perform meta-analysis of four studies that provided results on caloric and protein intake. Food-based fortification yielded positive results in the total amount of ingested calories and protein. Nevertheless, due to the small number of participants and the poor quality of some studies, further high quality studies are required to provide reliable evidence.Implications for practiceDespite the limited evidence, due to their simplicity, low cost, and positive results in protein and calories intake, simple dietary interventions based on the food-based fortification or densification with protein or energy of the standard diet could be considered in patients at risk of malnutrition.

Design of a case management model for people with chronic disease (Heart Failure and COPD). Phase I: modeling and identification of the main components of the intervention through their actors: patients and professionals (DELTA-icE-PRO Study)

BackgroundChronic diseases account for nearly 60% of deaths around the world. The extent of this silent epidemic has not met determined responses in governments, policies or professionals in order to transform old Health Care Systems, configured for acute diseases. There is a large list of research about alternative models for people with chronic conditions, many of them with an advanced practice nurse as a key provider, as case management. But some methodological concerns raise, above all, the design of the intervention (intensity, frequency, components, etc).Methods/DesignObjectives: General: To develop the first and second phases (theorization and modeling) for designing a multifaceted case-management intervention in people with chronic conditions (COPD and heart failure) and their caregivers. Specific aims: 1) To identify key events in people living with chronic disease and their relation with the Health Care System, from their point of view. 2) To know the coping mechanisms developed by patients and their caregivers along the story with the disease. 3) To know the information processing and its utilization in their interactions with health care providers. 4) To detect potential unmet needs and the ways deployed by patients and their caregivers to resolve them. 5) To obtain a description from patients and caregivers, about their itineraries along the Health Care System, in terms of continuity, accessibility and comprehensiveness of care. 6) To build up a list of promising case-management interventions in patients with Heart Failure and COPD with this information in order to frame it into theoretical models for its reproducibility and conceptualization. 7) To undergo this list to expert judgment to assess its feasibility and pertinence in the Andalusian Health Care. Design: Qualitative research with two phases: For the first five objectives, a qualitative technique with biographic stories will be developed and, for the remaining objectives, an expert consensus through Delphi technique, on the possible interventions yielded from the first phase. The study will be developed in the provinces of Almería, Málaga and Granada in the Southern Spain, from patients included in the Andalusian Health Care Service database with the diagnosis of COPD or Heart Failure, with the collaboration of case manager nurses and general practitioners for the assessment of their suitability to inclusion criteria. Patients and caregivers will be interviewed in their homes or their Health Centers, with their family or their case manager nurse as mediator.DiscussionFirst of a series of studies intended to design a case-management service for people with heart failure and COPD, in the Andalusian Health Care System, where case management has been implemented since 2002. Accordingly with the steps of a theoretical model for complex interventions, in this study, theorization and intervention modeling phases will be developed.

Effectiveness of olive oil for the prevention of pressure ulcers caused in immobilized patients within the scope of primary health care: study protocol for a randomized controlled trial.

BackgroundPressure ulcers are considered an important issue, mainly affecting immobilized older patients. These pressure ulcers increase the care burden for the professional health service staff as well as pharmaceutical expenditure. There are a number of studies on the effectiveness of different products used for the prevention of pressure ulcers; however, most of these studies were carried out at a hospital level, basically using hyperoxygenated fatty acids (HOFA). There are no studies focused specifically on the use of olive-oil-based products and therefore this research is intended to find the most cost-effective treatment and achieve an alternative treatment.Methods/designThe main objective is to assess the effectiveness of olive oil, comparing it with HOFA, to treat immobilized patients at home who are at risk of pressure ulcers. As a secondary objective, the cost-effectiveness balance of this new application with regard to the HOFA will be assessed. The study is designed as a noninferiority, triple-blinded, parallel, multi-center, randomized clinical trial. The scope of the study is the population attending primary health centers in Andalucía (Spain) in the regional areas of Malaga, Granada, Seville, and Cadiz. Immobilized patients at risk of pressure ulcers will be targeted. The target group will be treated by application of an olive-oil-based formula whereas the control group will be treated by application of HOFA to the control group. The follow-up period will be 16 weeks. The main variable will be the presence of pressure ulcers in the patient. Secondary variables include sociodemographic and clinical information, caregiver information, and whether technical support exists. Statistical analysis will include the Kolmogorov-Smirnov test, symmetry and kurtosis analysis, bivariate analysis using the Student’s t and chi-squared tests as well as the Wilcoxon and the Man-Whitney U tests, ANOVA and multivariate logistic regression analysis.DiscussionThe regular use of olive-oil-based formulas should be effective in preventing pressure ulcers in immobilized patients, thus leading to a more cost-effective product and an alternative treatment.Trial registrationClinicaltrials.gov identifier: NCT01595347.

Topical Olive Oil Is Not Inferior to Hyperoxygenated Fatty Aids to Prevent Pressure Ulcers in High-Risk Immobilised Patients in Home Care. Results of a Multicentre Randomised Triple-Blind Controlled Non-Inferiority Trial

Pressure ulcers represent a major current health problem and produce an important economic impact on the healthcare system. Most of studies to prevent pressure ulcers have been carried out in hospital contexts, with respect to the use of hyperoxygenated fatty acids and to date, no studies have specifically examined the use of olive oil-based substances. Methods and Design Main objective: To assess the effectiveness of the use of olive oil, comparing it with hyperoxygenated fatty acids, for immobilised home-care patients at risk of suffering pressure ulcers. Design: Non-inferiority, triple-blind, parallel, multicentre, randomised clinical trial. Scope: Population attending Primary Healthcare Centres in Andalusia (Spain). Sample: 831 immobilised patients at risk of suffering pressure ulcers. Results The follow-up period was 16 weeks. Groups were similar after randomization. In the per protocol analysis, none of the body areas evaluated presented risk differences for pressure ulcers incidence that exceeded the 10% delta value established. Sacrum: Olive Oil 8 (2.55%) vs HOFA 8 (3.08%), ARR 0.53 (-2.2 to 3.26) Right heel: Olive Oil 4 (1.27%) vs HOFA 5 (1.92)%, ARR0.65 (-1.43 to 2.73). Left heel: Olive Oil 3 (0.96%) vs HOFA 3 (1.15%), ARR0.2 (-1.49 to 1.88). Right trochanter: Olive Oil 0 (0%) vs HOFA 4 (1.54%), ARR1.54 (0.04 to 3.03). Left trochanter: Olive Oil 1 (0.32%) vs HOFA 1 (0.38%), ARR0.07 (-0.91 to 1.04). In the intention to treat analysis the lower limit of the established confidence interval was never exceeded. Discussion The results obtained confirmed that the use of topical extra-virgin olive oil to prevent PU in the home environment, for immobilised patients at high risk, is not inferior to the use of HOFA. Further studies are needed to investigate the mechanism by which olive oil achieves this outcome. Trial Registration Clinicaltrials.gov NCT01595347

Characteristics, consequences and prevention of falls in institutionalised older adults in the province of Malaga (Spain): a prospective, cohort, multicentre study

Objectives Falls are an important adverse event among institutionalised persons. It is in this clinical setting where falls occur more frequently than in any other, despite the measures commonly taken to prevent them. This study aimed to determine the characteristics of a typical institutionalised elderly patient who suffers a fall and to describe the physical harms resulting from this event. We then examined the association between falls and the preventive measures used. Methods This was a prospective cohort study in 37 nursing homes in Spain. The participants were all the nursing home residents institutionalised in these centres from May 2014 to July 2016. Participants were followed up for 9 months. During this period, two observations were made to evaluate the preventive measures taken and to record the occurrence of falls. Results 896 residents were recruited, of whom 647 completed the study. During this period, 411 falls took place, affecting 213 residents. The injuries caused by the falls were mostly minor or moderate. They took place more frequently among women and provoked 22 fractures (5.35%). The most commonly used fall prevention measure was bed rails (53.53% of cases), followed by physical restraint (16.79%). The latter measure was associated with a higher incidence of injuries not requiring stitches (OR=2.06, 95% CI 1.01 to 4.22, P=0.054) and of injuries that did require stitches (OR=3.51, 95% CI 1.36 to 9.01, P=0.014) as a consequence of falls. Bed rails protected against night-time falls. Conclusions Falls are a very common adverse event in nursing homes. The prevention of falls is most commonly addressed by methods to restrain movement. The use of physical restraints is associated with a greater occurrence of injuries caused by a fall.

A cost minimisation analysis of olive oil versus hyperoxygenated fatty acid treatment for the prevention of pressure ulcers in primary health care: A randomised controlled trial

Pressure ulcers represent a major current health problem and cause an important economic impact on the healthcare system. Most studies on the prevention of pressure ulcers have been carried out in hospital contexts, with respect to the use of hyperoxygenated fatty acids (HOFA), and to date no studies have specifically examined the use of olive oil‐based treatments. Aim: To evaluate the cost of using extra virgin olive oil, rather than HOFA, in the prevention of pressure ulcers among persons with impaired mobility and receiving home care. Study Design: Cost minimization analysis of the results obtained from a noninferiority, triple‐blind, parallel, multicenter, randomized clinical trial. Population attending primary healthcare centers in Andalusia (Spain). Study sample: 831 immobilized patients at risk of suffering pressure ulcers. These persons were included in the study and randomly assigned as follows: 437 to the olive oil group and 394 to the HOFA group. At the end of the follow‐up period, the results obtained by the olive oil group were not inferior to those of the HOFA group, and did not exceed the 10% delta limit. The total treatment cost for 16 weeks was €19,758 with HOFAs and €9,566 with olive oil. Overall, the olive oil treatment was €10,192 less costly. It has been concluded the noninferiority of olive oil makes this product an effective alternative for the prevention of pressure ulcers in patients who are immobilized and in a domestic environment. This treatment enables considerable savings in direct costs.

Development of the Andalusian Registry of Patients Receiving Community Case Management, for the follow‐up of people with complex chronic diseases

RATIONALE, AIMS AND OBJECTIVES Complex chronic diseases are a challenge for the current configuration of health services. Case management is a service frequently provided for people with chronic conditions, and despite its effectiveness in many outcomes, such as mortality or readmissions, uncertainty remains about the most effective form of team organization, structures and the nature of the interventions. Many processes and outcomes of case management for people with complex chronic conditions cannot be addressed with the information provided by electronic clinical records. Registries are frequently used to deal with this weakness. The aim of this study was to generate a registry-based information system of patients receiving case management to identify their clinical characteristics, their context of care, events identified during their follow-up, interventions developed by case managers and services used. METHODS The study was divided into three phases, covering the detection of information needs, the design and its implementation in the health care system, using literature review and expert consensus methods to select variables that would be included in the registry. RESULTS A total of 102 variables representing structure, processes and outcomes of case management were selected for their inclusion in the registry after the consensus phase. A web-based registry with modular and layered architecture was designed. The framework follows a pattern based on the model-view-controller approach. In its first 6 months after the implementation, 102 case managers have introduced an average number of 6.49 patients each one. CONCLUSIONS The registry permits a complete and in-depth analysis of the characteristics of the patients who receive case management, the interventions delivered and some major outcomes as mortality, readmissions or adverse events.
