Effectiveness of alternative vs traditional exercises on cardiac rehabilitation program utilization in women with or at high risk of cardiovascular disease: a systematic review protocol.

OBJECTIVE: This review will evaluate the effectiveness of alternative vs traditional forms of exercise on cardiac rehabilitation program utilization and other outcomes in women with or at high risk of cardiovascular disease. INTRODUCTION: Exercise-based cardiac rehabilitation programs improve health outcomes in women with or at high risk of cardiovascular disease. However, such programs are underutilized worldwide, particularly among women. Some women perceive traditional gym-based exercise in cardiac rehabilitation programs (eg, typically treadmills, cycle ergometers, traditional resistance training) to be excessively rigorous and unpleasant, resulting in diminished participation and completion. Alternative forms of exercise such as yoga, tai chi, qi gong, or Pilates may be more enjoyable and motivating exercise options for women, enhancing engagement in rehabilitation programs. However, the effectiveness of these alternative exercises in improving program utilization is still inconsistent and needs to be systematically evaluated and synthesized. INCLUSION CRITERIA: This review will focus on randomized controlled trials of studies measuring the effectiveness of alternative vs traditional forms of exercise on cardiac rehabilitation program utilization as well as clinical, physiological, or patient-reported outcomes in women with or at high risk of cardiovascular disease. METHODS: The review will follow the JBI methodology for systematic reviews of effectiveness. Databases including MEDLINE (Ovid), CINAHL (EBSCOhost), Cochrane CENTRAL, Embase (Ovid), Emcare (Ovid), Scopus, Web of Science, LILACS, and PsycINFO (Ovid) will be searched. Two independent reviewers will screen articles and then extract and synthesize data. Methodological quality will be assessed using JBI's standardized instruments. GRADE will be used to determine the certainty of evidence. REVIEW REGISTRATION: PROSPERO CRD42022354996.

Factors that sustain Indigenous youth mentoring programs: a qualitative systematic review protocol.

OBJECTIVE: This qualitative systematic review aims to identify the barriers and enablers to delivering and sustaining Indigenous youth mentoring programs for improving mental health and reducing suicide rates. INTRODUCTION: The United Nations has called for global action to address Indigenous youth suicide and suicidal behavior. Indigenous youth mentoring programs aimed at improving mental health and reducing suicide rates have been conducted at smaller scales at other sites. Mentoring is culturally appropriate as it empowers communities and aligns with the principles of community, teaching and learning, kinship, and holistic health. There is a gap in the understanding of what the barriers and enablers of mentoring are in addressing Indigenous youth mental health and, ultimately, Indigenous youth suicide. INCLUSION CRITERIA: This review will consider studies that include mentoring programs specifically targeted at Indigenous youth mental health and well-being that are based within a community or organization setting. METHODS: Databases to be searched include CINAHL, PubMed, PsycINFO, Scopus, and Embase, as well as grey literature within Trove, OpenGrey, Indigenous HealthInfoNet, and Informit Indigenous Collection. The search will be limited to articles written in English and published from 2007 to the present. Titles and abstracts will be screened by two independent reviewers; full-text studies will be retrieved and assessed against the inclusion criteria. Results will be recorded in a Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) diagram. Where possible, qualitative research findings will be pooled. Where textual pooling is not possible, the findings will be presented in narrative form.

Interventions to ensure medication safety in acute care: an umbrella review.

BACKGROUND: Medication errors are one of the leading avoidable sources of harm to hospital patients. In hospitals, a range of interventions have been used to reduce the risk of errors at each of the points they may occur, such as prescription, dispensing and/or administration. Systematic reviews have been conducted on many of these interventions; however, it is difficult to compare the clinical utility of any of the separate interventions without the use of a rigorous umbrella review methodology. OBJECTIVES: The aim of this umbrella review was to synthesize the evidence from all systematic reviews investigating the effectiveness of medication safety interventions, in comparison to any or no comparator, for preventing medication errors, medication-related harms and death in acute care patients. METHOD: The review considered quantitative systematic reviews with participants who were healthcare workers involved in prescribing, dispensing or administering medications. These healthcare workers were registered nurses, enrolled or licensed vocational nurses, midwives, pharmacists or medical doctors. Interventions of interest were those designed to prevent medication error in acute care settings. Eligible systematic reviews reported medication errors, medication-related harms and medication-related death as measured by error rates, numbers of adverse events and numbers of medication-related deaths. To qualify for inclusion, systematic reviews needed to provide a clearly articulated and comprehensive search strategy, and evidence of critical appraisal of the included studies using a standardized tool. Systematic reviews published in English since 2007 were included until present (March 2020). We searched a range of databases such MEDLINE, CINAHL, Web of Science, EMBASE, and The Cochrane Library for potentially eligible reviews. Identified citations were screened by two reviewers working independently. Potentially eligible articles were retrieved and assessed against the inclusion criteria and those meeting the criteria were then critically appraised using the JBI SUMARI instrument for assessing the methodological quality of systematic reviews and research syntheses. A predetermined quality threshold was used to exclude studies based on their reported methods. Following critical appraisal, data were extracted from the included studies by two independent reviewers using the relevant instrument in JBI SUMARI. Extracted findings were synthesized narratively and presented in tables to illustrate the reported outcomes for each intervention. The strength of the evidence for each intervention was indicated using 'traffic light' colors: green for effective interventions, amber for interventions with no evidence of an effect and red for interventions less effective than the comparison. RESULTS: A total of 23 systematic reviews were included in this umbrella review. Most reviews did not report the number of participants in their included studies. Interventions targeted pharmacists, medical doctors, medical students and nurses, or were nonspecific about the participants. The majority of included reviews examined single interventions. All reviews were published and in English. Four interventions, medication administration education, medication reconciliation or review, specialist pharmacists' roles and physical or design modifications, reported effectiveness in reducing errors; however, heterogeneity between the included studies in these reviews was high. CONCLUSION: For some interventions, there are strong indications of effectiveness in reducing medication errors in the inpatient setting. Government initiatives, policy makers and practitioners interested in improving medication safety are encouraged to adopt those interventions.

Aromatherapy for treatment of postoperative nausea and vomiting.

BACKGROUND: Postoperative nausea and vomiting (PONV) is a common, unpleasant phenomenon and current therapies are not always effective for all patients. Aromatherapy has been suggested as an addition to the available treatment strategies. This review was originally published in 2012 and updated in 2017. OBJECTIVES: The main objective was to establish the efficacy and safety of aromatherapy comparable to standard pharmacological treatments for PONV in adults and children. SEARCH METHODS: We searched CENTRAL; MEDLINE; Embase; CINAHL; CAM on PubMed; Informit; LILACS; and ISI Web of Science as well as grey literature sources and the reference lists of retrieved articles up to March 2017. The original search was performed in August 2011. SELECTION CRITERIA: We included all randomized controlled trials (RCTs) and controlled clinical trials (CCTs) where aromatherapy was used to treat PONV. Interventions were all types of aromatherapy compared to placebo or with standard antiemetics. Primary outcomes were severity and duration of PONV. Secondary outcomes were adverse reactions, use of rescue antiemetics and patient satisfaction. DATA COLLECTION AND ANALYSIS: Two review authors independently assessed risk of bias in the included studies and extracted data. For dichotomous outcome variables, we used a random-effects model and calculated risk ratio (RR) with associated 95% confidence interval (95% CI). For continuous outcome variables, we used a random-effects model and calculated standardized mean difference (SMD) with associated 95% CI. We used the GRADE software to compile 'Summary of findings' tables. MAIN RESULTS: We included seven new studies with 663 participants in the 2017 update; five RCTs and two CCTs. These were added to the nine previously included studies (six RCTs and three CCTs with a total of 373 participants) for a total of 16 included studies and 1036 participants in this updated review. The mean age and range data for all participants were not reported for all studies. We identified two registered trials that met the inclusion criteria for this review; however there are no results for these studies yet.Overall, the GRADE assessment of evidence quality ranged from moderate to very low. The method of randomization in 11 of the 12 included RCTs was explicitly stated and adequate. Incomplete or methodologically diverse reporting of data affected the completeness of the analysis. Data on additional aromatherapies were added in the 2017 update (blended aromatherapy products, and peppermint products). Heterogeneity of outcome measures and time points between studies affected the completeness of the analysis.In the summary of the findings of six studies, we did not find aromatherapy to be effective in reducing nausea severity in comparison to placebo (SMD -0.22, 95% CI -0.63 to 0.18, P value = 0.28, 241 participants, level of evidence: low). Those participants receiving aromatherapy were no more likely to be free of nausea at the end of the treatment period than those receiving placebo (RR 3.25, 95% CI 0.31 to 34.33, P value = 0.33, 4 trials, 193 participants, evidence level: very low), however they were less likely to require rescue antiemetics (RR 0.60, 95% CI 0.37 to 0.97, P value = 0.04, 7 trials, 609 participants, evidence level: low). There were no data reported on adverse events or patient satisfaction for this comparison.A specific comparison of peppermint aromatherapy to placebo did not show evidence of an effect on nausea severity at five minutes post-treatment in the pooled results (SMD -0.18, 95% CI -0.86 to 0.49, P value = 0.59, 4 trials, 115 participants, evidence level: low). There were no data reported on nausea duration, use of rescue antiemetics, adverse events or patient satisfaction for this comparison.When we pooled studies comparing isopropyl alcohol to standard antiemetic treatment in a GRADE summary of findings, in terms of nausea duration, there was a significant effect on the time in minutes to a 50% reduction in nausea scores (SMD -1.10, 95% CI -1.43 to -0.78, P value < 0.00001, 3 trials, 176 participants, evidence level: moderate). Fewer participants who received isopropyl alcohol required rescue antiemetics (RR 0.67, 95% CI 0.46 to 0.98, P value = 0.04, 215 participants, 4 trials, evidence level: moderate). Two studies with 172 participants measured patient satisfaction; there were high levels of satisfaction across both aromatherapy and standard treatment groups and no differences found (evidence level: low). There were no data reported on nausea severity or adverse events for this comparison.There was no difference in effectiveness between isopropyl alcohol vapour inhalation and placebo for reducing the proportion of participants requiring rescue antiemetics (RR 0.39, 95% CI 0.12 to 1.24, P value = 0.11, 291 participants, 4 trials, evidence level: very low). There were no data reported on nausea severity, nausea duration, adverse events or patient satisfaction for this comparison. AUTHORS' CONCLUSIONS: Overall, for nausea severity at the end of treatment, aromatherapy may have similar effectiveness to placebo and similar numbers of participants were nausea-free. However, this finding is based on low-quality evidence and therefore very uncertain. Low-quality evidence also suggests that participants who received aromatherapy may need fewer antiemetic medications, but again, this is uncertain. Participants receiving either aromatherapy or antiemetic medications may report similar levels of satisfaction with their treatment, according to low-quality evidence.

Effectiveness of meaningful occupation interventions for people living with dementia in residential aged care: a systematic review.

BACKGROUND: The ability to participate in valued activities, whether for work, leisure or family, is an important aspect of personal identity. In dementia, progressive memory loss means that abilities developed over a lifetime begin to be lost as well, contributing to the loss of self and identity. Some studies have reported that activities or interventions tailored to be meaningful to the person with dementia (defined as any activity important to the individual) are more effective in addressing behavioral and psychological symptoms of dementia (BPSD) and improving quality of life (QoL) than those that are not so tailored. However, the effectiveness of individualizing interventions or activities for this population is not known. OBJECTIVES: In response to consumer feedback by the Consumer Dementia Research Network that this question ought to be addressed, this review was undertaken, the aim of which was to determine the effectiveness of meaningful occupation interventions for people living with dementia in residential aged care facilities (RACFs). INCLUSION CRITERIA: People living with dementia in RACFs (nursing homes).Any intervention that was individualized to be meaningful to the participant, versus any active control condition or usual care.Experimental and observational studies. TYPES OF OUTCOMES: Quality of life, BPSD (such as agitation, aggression, depression, wandering and apathy), mood, function, cognition and sleep. SEARCH STRATEGY: The search strategy aimed to identify both published and unpublished studies, with the following 12 databases extensively searched: PubMed, CINAHL, PsycINFO, ISI Web of Science, OTSeeker, Embase, Cochrane CENTRAL, clinicaltrials.gov, Mednar, OpenSIGLE, New York Academy of Medicine Library Gray Literature Report, ProQuest Dissertations and Theses. The search strategy was limited to papers published in English between 2004 and January 31, 2015. METHODOLOGICAL QUALITY: All studies were assessed independently by two reviewers for relevance, eligibility and methodological quality. DATA EXTRACTION: Data from included papers were extracted using a standard data extraction tool. DATA SYNTHESIS: Where possible, study results were pooled in statistical meta-analysis. Alternatively, results are presented in narrative and tabular form. RESULTS: A total of 5274 citations were identified; after removal of duplicates, assessment for relevance and eligibility, 61 studies underwent critical appraisal. Thirty-four studies met the quality criteria and were included in a quantitative synthesis. A wide range of interventions were evaluated including individualized recreational activities (13 studies), reminiscence therapy (RT) (seven studies), music therapy interventions (six studies), training staff to develop individual care plans using person-centered care (PCC) or similar approaches (three studies), animal-assisted therapy (two studies), multi-sensory interventions (MSIs) (two studies) and social interaction (one study), all of which measured a number of different outcomes. Overall, and in spite of most studies being small-scale and of relatively brief duration, all interventions with the exception of Snoezelen therapy (a MSI) reported some benefits for people with dementia living in RACFs. The most frequently reported benefits were reductions in agitation (the most frequently assessed outcome), passivity and depression, improved QoL and increases in pleasure and interest. However, the majority of studies generally implemented the intervention, whether it was individualized activities, music or RT or other, in conjunction with one-to-one social interaction, and the relative importance of the intervention in comparison to one-to-one social contact for effectiveness cannot be determined from this review. CONCLUSION: Providing meaningful or individualized tailored activities for people with dementia living in RACFs appears to be effective for a range of behavioral and psychological symptoms. The strongest evidence was for individualized activities/recreational interventions for a range of BPSD; preferred music for agitation, depression and anxiety; and RT for mood and cognitive functioning. Insufficient evidence precluded making recommendations regarding animal-assisted (dog) therapy and training staff to develop individual care plans using PCC or similar approaches, while there was no good quality evidence to show that Snoezelen was effective for any outcome. What remains unclear, however, is whether any of these interventions is more effective than the provision of one-to-one social interaction.

Nutritional interventions for optimizing healthy body composition in older adults in the community: an umbrella review of systematic reviews.

BACKGROUND: Optimizing body composition for healthy aging in the community is a significant challenge. There are a number of potential interventions available for older people to support both weight gain (for those who are underweight) and weight loss (for overweight or obese people). While the benefits of weight gain for underweight people are generally clearly defined, the value of weight loss in overweight or obese people is less clear, particularly for older people. OBJECTIVES: This umbrella review aimed to measure the effectiveness of nutritional interventions for optimizing healthy body composition in older adults living in the community and to explore theirqualitative perceptions. INCLUSION CRITERIA TYPES OF PARTICIPANTS: The participants were older adults, 60 years of age or older, living in the community. TYPES OF INTERVENTIONS: The review examinedsix types of nutritional interventions: (i) dietary programs, (ii) nutritional supplements, (iii) meal replacements, (iv) food groups, (v) food delivery support and eating behavior, and (vi) nutritional counselling or education. TYPES OF STUDIES: This umbrella review considered any quantitative systematic reviews and meta-analyses of effectiveness, or qualitative systematic reviews, or a combination (i.e. comprehensive reviews). TYPES OF OUTCOMES: The quantitative outcome measures of body composition were: (i) nutritional status (e.g. proportion of overweight or underweight patients); (ii) fat mass (kg), (iii) lean mass or muscle mass (kg), (iv) weight (kg) or BMI (kg/m), (v) bone mass (kg) or bone measures such as bone mineral density, and (vi) hydration status. PHENOMENA OF INTEREST: The phenomena of interestwere the qualitative perceptions and experiences of participants. SEARCH STRATEGY: We developed an iterative search strategy for nine bibliometric databases and gray literature. METHODOLOGICAL QUALITY: Critical appraisal of 13 studies was conducted independently in pairs using standard Joanna Briggs Institute tools. Six medium quality and seven high quality studies were identified. DATA EXTRACTION: Data was extracted independently in pairs from all 13 included studies using the standard Joanna Briggs Institute data extraction tool. DATA SUMMARY: Only quantitative studies of effectiveness were included. The strength of evidence assessing the effectiveness of interventionswas graded using a traffic light system (green, amber, red). An overall assessment of the quality of the evidence for each comparison was undertaken. RESULTS: More systematic reviews investigating weight gain than those investigating weight loss were included. Studies onweight gain showed improved body composition for oral nutritional supplements on its own, for oral nutritional supplements in combination with resistance exercise training, and for oral nutritional supplements in combination with nutrition counselling. Studies on weight loss showed that diet in combination with exercise, diet in combination with exercise and nutrition counselling, and nutrition counselling on its own all can lead to reduced weight in older people. The outcomes of lean mass and weight/BMI were responsive to nutritional interventions, but fat mass did not vary. There were no qualitative reviews identified. CONCLUSIONS: Although effective interventions for weight gain and weight loss to optimize body composition of older people in the community were identified,making long term, clinically relevant changes in body composition is difficult. Multiple interventions are more effective than single interventions.

Effectiveness of professional oral health care intervention on the oral health of residents with dementia in residential aged care facilities: a systematic review protocol.

REVIEW QUESTION/OBJECTIVE: The objective of this review is to critically appraise and synthesize evidence on the effectiveness of professional oral health care intervention on the oral health of aged care residents with dementia.More specifically the objectives are to identify the efficacy of professional oral health care interventions on general oral health, the presence of plaque and the number of decayed or missing teeth. BACKGROUND: Dementia poses a significant challenge for health and social policy in Australia. The quality of life of individuals, their families and friends is impacted by dementia. Older people with dementia often have other health comorbidities resulting in the need for a higher level of care. From 2009 to 2010, 53% of permanent residents in Residential Aged Care Facilities (RACFs) had dementia on admission. Older Australians are retaining more of their natural teeth, therefore residents entering RACFs will have more of their natural teeth and require complex dental work than they did in previous generations. Data from the Australian Institute of Health and Welfare showed that more than half the residents in RACFs are now partially dentate with an average of 12 teeth each. Furthermore, coronal and root caries are significant problems, especially in older Australians who are cognitively impaired.Residents in aged care facilities frequently have poor oral health and hygiene with moderate to high levels of oral disease and overall dental neglect. This is reinforced by aged care staff who acknowledge that the demands of feeding, toileting and behavioral issues amongst residents often take precedence over oral health care regimens. Current literature shows that there is a general reluctance on the part of aged care staff to prioritize oral care due to limited knowledge as well as existing psychological barriers to working on another person's mouth. Although staff routinely deal with residents' urinary and faecal incontinence, deep psychological barriers exist when working on someone's mouth due to their own personal values of oral health or their views that residents should be looking after their own teeth or dentures. Furthermore, residents with behavioral issues associated with dementia frequently have their oral hygiene neglected as they may be resistant and violent towards receiving oral care from aged care staff. Studies have shown that residents with dementia will often refuse to open their mouth or partake in oral hygiene care by aged care staff. The aged care staff in return often do not pursue an oral care regimen for these "difficult" residents, perpetuating the cycle of oral neglect and resultant disease.Dental hygienists are qualified oral health professionals who are specifically trained to develop individualized oral health care plans and preventative programs to reduce oral health disease in the community. Residents with dementia in aged care facilities have the right to live their lives comfortably and free of oral discomfort or pain. A Victorian study conducted by Hopcraft et al. investigated the ability of a dental hygienist to undertake a dental examination/screening for residents in aged care facilities, to develop a preventative and periodontal treatment plan and to refer patients appropriately to a dentist. Results from this study demonstrated that there was an excellent agreement between the dentist and dental hygienist regarding the decision to refer residents to a dentist for treatment, demonstrating high sensitivity (99.6%) and high specificity (82.9%). Residents from 31 Victorian RACFs (n=510) were examined by a single experienced dental epidemiologist and one of four dental hygienists using a simple mouth mirror and probe. Hopcraft et al. concluded that hygienists should be utilized more widely in providing holistic oral health care to residents in aged care facilities.Recently, Lewis et al. discussed the need to develop models of care to improve access to dental care for frail and functionally dependent elderly people in aged care facilities, with the model of care involving dental hygienists/oral health therapists having merit.The concept of professional oral care involves an oral health professional such as a dental hygienist or oral health therapist supervising or assisting residents with their oral care. Oral care involves the mechanical removal of plaque and food debris using a toothbrush, interproximal brush and floss.In 2014, Morino et al. explored the efficacy of short term professional oral care from dental hygienists once a week after breakfast for one month. In this study, the dental hygienists did not perform dental scaling but brushed subjects' teeth using a toothbrush and interdental brush. Dental plaque scores decreased significantly (Fisher's two-tailed tests, p<0.05) in the professional oral health intervention group. Interestingly, the positive effects of this short term intervention were sustained for the following three months (Wilcoxon test, p<0.05).A pilot study in Arkansas was conducted by Amerine et al. and utilized the dental hygienist as the "oral health champion" in the residential aged care facility using the Oral Health Assessment Tool (OHAT) and Geriatric Oral Health Assessment Index (GOHAI) scores to measure oral health. The results from this study showed improvements in three measured areas (tongue health, denture status and oral cleanliness) in the dental hygiene champion group. These findings suggest that the presence of a dental hygiene champion in long term care facilities may positively impact the oral health of residents requiring assistance with their oral care. However, the authors noted further research in this concept is required.Van Der Putten GJ et al. explored the effectiveness of a supervised implementation of an oral health care guideline in care homes. In each ward of the care homes, a nurse who acted as the ward oral health care organiser (WOO) was appointed. The dental hygienist and an investigator would attend the RACFs every six weeks to support them. The dental hygienist would train the WOO, and the WOO would train the ward nurses and nurse assistants. Participants were allocated into an intervention or a control group. The intervention group received supervised oral care. Statistically significant differences in mean dental and denture plaque scores at six months in both groups occurred (student t-test, p < 0.0001). This research study implemented an intervention using the train-the-trainer approach and although improvements in dental and denture plaque scores were seen in the six-month period, the long-term effects of this intervention are unknown. Further studies exploring the long-term effects of staff training on oral health education are needed as well as ongoing staff training in aged care facilities.A systematic review on oral health and aspiration pneumonia conducted by Vander Maarel-Wierink et al. has suggested that, in the frail elderly, the best intervention to reduce the incidence of aspiration pneumonia is brushing of teeth after each meal, cleaning dentures once a day, and receiving professional oral health care once a week.The need to advocate for a new model of geriatric dentistry is critical. A holistic multi-disciplinary approach to health care for residents entering aged care homes is imperative to achieve better oral health and comfort for residents, especially with Australia's ageing dentate population. A dental examination and assessment on admission to a RACF should be conducted by a Registered Nurse (RN), followed by an oral health professional such as a dentist, dental hygienist or oral health therapist. Current practice in the majority of Australian government funded nursing homes is that the RN or the Assistant in Nursing (AIN) conduct the oral health assessment as part of the aged care funding instrument (ACFI). Ongoing oral health care supported by an oral health professional is important throughout the individual's residency and eventual palliation whilst in an aged care facility.No systematic reviews conducted on the impact of professional oral care on the oral health of elderly people living in residential aged care facilities could be located, despite extensive searching of Medline, CINAHL, EMBASE, Web of Science, Cochrane Central Register of Trials and Dentistry & Oral Sciences Source (DOSS) databases. A JBI systematic review was conducted in 2004, titled, "Oral hygiene care for adults with dementia in residential aged care facilities"; however, this review examined the prevalence, incidence and increments of oral diseases; the use of assessment tools to evaluate oral health; preventative oral hygiene care strategies; and the provision of dental treatment and so had a different clinical focus. Twenty studies were included for analysis in the review conducted by Weening-Verbree et al, The studies in this review addressed oral health knowledge of aged care staff and mostly were conducted as an educational session delivered by dental hygienists or dentists.Overall, the current evidence available on interventions to improve oral health for residents living in aged care facilities is inadequate and should be explored further.

The effectiveness of prehabilitation or preoperative exercise for surgical patients: a systematic review.

BACKGROUND: Major surgery can induce functional decline and pain, which can also have negative implications on health care utilization and quality of life. Prehabilitation is the process of optimizing physical functionality preoperatively to enable the individual to maintain a normal level of function during and after surgery. Prehabilitation training can be a combination of aerobic exercises, strength training, and functional task training to suit individual needs. OBJECTIVES: To evaluate the impact of prehabilitation on physical functional status, health care utilization, quality of life, and pain after surgery. INCLUSION CRITERIA: Studies of adult surgical patients, excluding day surgery patients.Any preoperative exercise interventions identified in the study as part of a prehabilitation or preoperative exercise program, versus usual care.Randomized controlled trials.Functional status, health care utilization, quality of life and pain. SEARCH STRATEGY: Published (CINAHL, CENTRAL, EMBASE, MEDLINE, PEDro) and unpublished studies between 1996 and March 2013 were searched extensively. METHODOLOGICAL QUALITY: All studies were assessed independently by two reviewers for relevance, eligibility and methodological quality. DATA COLLECTION: Data from included papers were extracted using a modified data extraction tool. DATA SYNTHESIS: Where possible, study results were pooled in statistical meta-analysis. Alternatively, results are presented in narrative and table form. RESULTS: A total of 3167 citations were identified; after removal of duplicates, assessment for relevance and eligibility, 33 studies underwent critical appraisal. Seventeen studies met the quality criteria and were included in quantitative synthesis. Thirteen studies were conducted in orthopedics (mainly knee or hip arthroplasty for osteoarthritis), one in colorectal, two in cardiac and one in upper gastrointestinal/hepatobiliary. Function, pain and quality of life were quantified according to prehabilitation dose and postoperative months. Prehabilitation, at any dose, did not demonstrate benefits in objective and self-reported function at any of the postoperative time points. Prehabilitation did not demonstrate benefits in quality of life or pain; however, there was significant evidence that prehabilitation doses of more than 500 minutes reduced the need for postoperative rehabilitation, but no significant reduction was found in readmissions or nursing home placement. CONCLUSIONS: Results from this review reveal that prehabilitation has no significant postoperative benefits in function, quality of life and pain in patients who have had knee or hip arthroplasty for osteoarthritis; however, there is evidence that prehabilitation may reduce admission to rehabilitation in this population. The evidence on postoperative benefits of prehabilitation in other surgical populations is limited; however, preliminary evidence does not demonstrate better outcomes. IMPLICATIONS FOR PRACTICE: There is no evidence that prehabilitation provides benefits in function, pain or quality of life in patients who have had arthroplasty for osteoarthritis; however prehabilitation doses of more than 500 minutes might reduce acute rehabilitation admissions. The evidence is insufficient to provide recommendations on the benefits of prehabilitation in other surgical populations. IMPLICATIONS FOR RESEARCH: Future prehabilitation studies are not recommended in patients with osteoarthritis for whom arthroplasty is planned. However, should prehabilitation be tested in other surgical populations, programs must consider patient suitability, setting, delivery of intervention and clinical effectiveness. It is also recommended that the exercises prescribed should be maintained and adhered to after surgery. Most importantly, prehabilitation studies must have adequately powered sample sizes.

Aromatherapy for treatment of postoperative nausea and vomiting.

BACKGROUND: Postoperative nausea and vomiting is a common and unpleasant phenomenon and current therapies are not always effective for all patients. Aromatherapy has been suggested as a possible addition to the available treatment strategies. OBJECTIVES: This review sought to establish what effect the use of aromatherapy has on the severity and duration of established postoperative nausea and vomiting and whether aromatherapy can be used with safety and clinical effectiveness comparable to standard pharmacological treatments. SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2011, Issue 3); MEDLINE; EMBASE; CINAHL; CAM on PubMed; Meditext; LILACS; and ISI Web of Science as well as grey literature sources and the reference lists of retrieved articles. We conducted database searches up to August 2011. SELECTION CRITERIA: We included all randomized controlled trials (RCTs) and controlled clinical trials (CCTs) where aromatherapy was used to treat postoperative nausea and vomiting. Interventions were all types of aromatherapy. Aromatherapy was defined as the inhalation of the vapours of any substance for the purposes of a therapeutic benefit. Primary outcomes were the severity and duration of postoperative nausea and vomiting. Secondary outcomes were adverse reactions, use of rescue anti-emetics and patient satisfaction with treatment. DATA COLLECTION AND ANALYSIS: Two review authors assessed risk of bias in the included studies and extracted data. As all outcomes analysed were dichotomous, we used a fixed-effect model and calculated relative risk (RR) with associated 95% confidence interval (95% CI). MAIN RESULTS: The nine included studies comprised six RCTs and three CCTs with a total of 402 participants. The mean age and range data for all participants were not reported for all studies. The method of randomization in four of the six included RCTs was explicitly stated and was adequate. Incomplete reporting of data affected the completeness of the analysis. Compared with placebo, isopropyl alcohol vapour inhalation was effective in reducing the proportion of participants requiring rescue anti-emetics (RR 0.30, 95% CI 0.09 to 1.00, P = 0.05). However, compared with standard anti-emetic treatment, isopropyl alcohol was not effective in reducing the proportion of participants requiring rescue anti-emetics (RR 0.66, 95% CI 0.39 to 1.13, P = 0.13) except when the data from a possibly confounded study were included (RR 0.66, 95% CI 0.45 to 0.98, P = 0.04). Where studies reported data on patient satisfaction with aromatherapy, there were no statistically significant differences between the groups (RR 1.12, 95% CI 0.62 to 2.03, P = 0.71). AUTHORS' CONCLUSIONS: Isopropyl alcohol was more effective than saline placebo for reducing postoperative nausea and vomiting but less effective than standard anti-emetic drugs. There is currently no reliable evidence for the use of peppermint oil.

Oral liquid nutritional supplements for people with dementia in residential aged care facilities.

AIM: This systematic review investigated the prescription, administration and effectiveness of oral liquid nutritional supplements (OLNS) for people with dementia in residential aged care facilities (RACF). METHODS: A comprehensive search of relevant databases, hand searching and cross-referencing found 15 relevant articles from a total of 2910 possible results. Articles which met the inclusion criteria were critically appraised by two independent reviewers using the relevant Joanna Briggs Institute (JBI) appraisal checklist. Data were extracted using the relevant JBI extraction instruments. No data synthesis was possible due to clinical and methodological heterogeneity. RESULTS: Included studies examined a range of strategies, issues and results related to OLNS for persons with dementia in RACFs; however there appear to be significant gaps in the current body of research, particularly in relation to examinations of effectiveness. CONCLUSIONS: This review was unable to produce a definitive finding regarding effectiveness. OLNS may improve the nutritional state of residents with dementia and help prevent weight loss, and there is some suggestion that it may slow the rate of cognitive decline. However, in order for OLNS to be effective, nursing and care staff need to ensure that sufficient attention is paid to the issues of prescription and administration.
