ReviewThe effect of weight management interventions that include a diet component on weight-related outcomes in pregnant and postpartum women: a systematic review protocol.
What are the effects of weight management interventions that include a diet component on weight-related outcomes in pregnant and postpartum women?The primary objective of this systematic review is to evaluate the effectiveness of weight management interventions which include a diet component and are aimed at limiting gestational weight gain and postpartum weight retention in women.The second objective of this systematic review is to investigate included intervention components with respect to effect on weight-related outcomes. This may include, but is not limited to: length of intervention, use of face-to-face counselling, group or individual consultations, use of other interventions components including exercise, use of goals and use of support tools like food diaries, coaching, including email or text message support. ⋯ Around half of all women of reproductive age are either overweight or obese, with women aged 25-34 years having a greater risk of substantial weight gain compared with men of all ages. Excessive gestational weight gain (GWG) and postpartum weight retention (PPWR) may play a significant role in long term obesity. Having one child doubles the five- and 10-year obesity incidence for women, with many women who gain excessive weight during pregnancy remaining obese permanently. Excessive GWG and/or PPWR can also significantly contribute to short- and long-term adverse health outcomes for mother, baby and future pregnancies.Maternal obesity increases the risk of pregnancy related complications such as pre-eclampsia, gestational diabetes mellitus, stillbirth and the rate of caesarean section. Childhood obesity is a further long term complication of maternal obesity for offspring, which may persist in to adulthood. Excess GWG is also a risk factor for PPWR both in the short and long-term. Nehring et al. conducted a meta-analysis with over 65,000 women showing that, compared to women who gained weight within recommendations during pregnancy, women with GWG above Institute of Medicine weight gain recommendations, retained an additional 3.1 kg and 4.7kg after three and greater than or equal to 15 years postpartum, respectively. The health risk associated with PPWR is highlighted in a study of 151,025 Swedish women followed between 1992 and 2001.The study identified the risk of adverse pregnancy outcomes for those who gained three or more units of Body Mass Index (kg/m2) between consecutive pregnancies (an average of two years) was much higher compared with women whose BMI changed from -1.0 and 0.9 units. Long-term chronic disease risk may also be affected by PPWR as weight retention at the end of the first year post-partum has been found to be a predictor of maternal overweight 15 years later.With around 14-20% of women retaining 5kg or more 12 months postpartum, the risk of developing conditions like diabetes, metabolic syndrome and cardiovascular disease may be increased. It becomes evident that interventions which aim to support attainment of healthy weight both in the antenatal and postpartum periods are key health priorities for women during this life stage.Lifestyle factors of overweight, having poor diet quality, and not undertaking enough moderate-to-vigorous physical activity are amongst the top five predictors of mortality in women. Additionally it is noted that, for many women, pregnancy and the postpartum period are associated with a reduction in physical activity. It is known that a combination of poor dietary choices, an increase in sedentary time and reduction in physical activity are all contributors to the development of overweight and obesity. With this in mind, current research has focused on lifestyle interventions to limit GWG and PPWR. Thangaratinam et al. reviewed 44 randomized controlled trials (7278 women) where interventions including diet, physical activity or both were evaluated for their influence on maternal weight during pregnancy. Results indicate that all were significantly effective in reducing GWG compared with the control group. More specifically, dietary interventions were the most effective in reducing weight gain, with a mean weight loss of -3.84kg compared with -0.72kg and -1.06kg for physical activity and the mixed (diet plus physical activity) approach, respectively. This finding is supported by Hill and colleagues' recent systematic review of theory based interventions to limit GWG. Included studies in this review reported an underpinning theory base and were classified as adopting a dietary, physical activity or mixed approach. Hill et al. concluded that studies which included a diet intervention were significantly more effective at limiting GWG.In 2011 Tanentsapf et al. reviewed the effect of dietary interventions alone for reducing GWG in normal weight, overweight and obese pregnant women. This review analysed 13 randomized controlled trials and quasi-randomized controlled trials with a dietary intervention to prevent excessive GWG in women. The review concluded that dietary interventions during pregnancy were effective in reducing GWG with an effect of -1.92kg (n=1434) compared with the control group.Tanentsapf et al. identified that trials differed in the conduct of the interventions with various diet and non-diet related components utilised. Dietary approaches were highly variable with some trials focusing only on calorie restriction and others included additional target macronutrient distribution for intake. Some trials further provided feedback based on maternal weight gain guidelines. Interventions also varied in delivery method with a variety of modes used, including face-to-face, individual or group consultations and/or written correspondence. The frequency of communication, despite the type or mix, also changed from trial to trial with additional methods via telephone, posted materials, feedback or food diaries utilised. The inclusion of physical activity in addition to diet intervention was also common. Whilst the recent review by Tanentsapf et al. identified that dietary interventions are effective in reducing GWG, the review did not investigate the impact that different intervention components, delivery methods or dietary counselling approaches had on gestational weight management. It remains unclear as to which intervention components optimize GWG in women.The impact of lifestyle interventions has also been investigated in the postpartum period. The recent systematic review from van der Pligt et al. reported seven of 11 studies reviewed were successful in limiting PPWR. As with studies aimed at limiting GWG, interventions included in van der Pligt et al.'s review differed greatly in their conduct. Six of these seven studies included both dietary and physical activity components for the intervention, with the final successful study including a diet only intervention. Five of the successful studies recruited overweight or obese women only. Intervention time varied considerably in successful studies with some running for as little at ten days, and others up to six months.Bertz et al. demonstrated that their 12-week behavior modification intervention which targeted diet alone or diet and exercise, including two individual sessions with a dietitian and physical therapist, provision of scales for weight self-monitoring and bi-weekly text messages was successful in achieving significant weight loss following the intervention, and sustained at one year. The diet intervention and the diet and exercise intervention yielded significant weight loss compared to the control. Following 12 weeks a reduction of -8.3 +/- 4.2kg for diet intervention and -6.9 +/- 3.0kg for diet and exercise was observed. Additionally after one year, the diet intervention showed -10.2 +/- 5.7kg reduction and -7.3 +/- 6.3kg for the diet and exercise intervention (p<0.001). Colleran et al. also found significant weight change results by implementing a 16-week intervention which consisted of weekly individual sessions with a dietitian regarding calorie restriction, two additional home visits regarding exercise, weekly food diary completion and email support. The intervention group had greater weight loss compared to the control group (-5.8kg +/- 3.5kg vs -1.6kg +/- 5.4kg). It can be seen that various methods have been utilized in investigating the impact of diet and physical activity interventions on PPWR. The review by van der Pligt et al. highlights the impact successful lifestyle interventions can have on postpartum weight change. However, this review did not investigate the different intervention strategies utilized. It remains unclear as to the optimal setting, delivery method, diet strategy, contact frequency or intervention length to limit PPWR.Previous systematic reviews for both GWG and PPWR have focused on the effectiveness of lifestyle interventions as a whole for weight management in pregnant and postpartum women. And despite Tanentsapf et al.'s focus on dietary interventions for GWG, much is still unknown about the effectiveness of differing diet interventions over the antenatal and postpartum period. Specifically, the impact of differing diet intervention strategies on maternal weight gain is not known. Firstly, this systematic review will focus on whether weight management interventions which include a dietary component are effective in pregnant and postpartum women. In addition to this, this review will investigate the different intervention strategies utilized and their effectiveness in maternal weight management. A search of systematic review protocol databases has shown that there is no current review underway for this topic.

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

ReviewThe experiences of family members in the year following the diagnosis of a child or adolescent with cancer: a qualitative systematic review.
Research shows that it is stressful for family members when a child or an adolescent within the family unit is diagnosed with cancer and this stress continues over the course of the year after the diagnosis. Qualitative studies have been conducted aimed at exploring parental, siblings' and other family members' experiences when facing health-illness transition-related stress during the first year after the child is diagnosed with cancer. This study integrates the research findings of relevant existing qualitative studies on this topic in order to provide empirical evidence-based suggestions for clinical care. ⋯ Clinical guideline suggestions for health professionals working with families of children or adolescent diagnosed with cancer within the first year following the diagnosis were identified. Health professionals must listen to and accept the emotions of shock, anger and loss by the family members who are facing the potential loss of their healthy child together with the upheaval in their lives and disruptions to their plans for the future. Health professionals should be encouraged to provide clear information to the whole family in relation to the treatment plan and caring strategies for the child. Nurses should provide family members with strategies to help with the normalization of their life and a return to their previous pre-cancer lifestyle. The medical team should exhibit professionalism and skills when treating the cancer in order to enhance the child’s and his/her family members’ trust and sense of safety in the medical care environment. Encouraging the family members of children with cancer to develop positive thinking and to plan for their future life should be a priority of the nursing care plan.

ReviewDiagnostic accuracy of methods used to verify nasogastric tube position in mechanically ventilated adult patients: a systematic review.
Nasogastric tubes are widely used in hospitals, e.g. for the administration of nutrients. However, nasogastric tubes can be inserted accidently into the airways leading to complications like pneumonia, pneumothorax and even death. Mechanically ventilated patients are at high risk of having a nasogastric tube misplaced, since they often have reduced consciousness and weak cough reflex. A variety of methods have been used for determination of nasogastric tube placement, but with varying success. ⋯ We found evidence (Level 2b) for colorimetric capnography to be a valid method for verifying nasogastric tube placement.Capnography also detected nasogastric tube position with very high accuracy. However, since these methods were tested in only a single study with a limited sample size, further research is required before clinical recommendations can be made.Despite the impressive results obtained by using colorimetric capnography, implication for practice is not straightforward. A concern is that the colorimetric capnograph is not produced by the manufacture to fit a NG tube and therefore has to be connected to the NG tube by an adaptor-system. Practical issues therefore have to be resolved if the method is supposed to become a standard procedure in a clinical setting.The execution of the procedure using colorimetric capnography differs between the studies. This systematic review therefore recommends that further research should be done to optimize the execution of the procedure.We also recommend that further research be done to reproduce the results obtained using capnography, since this method was tested only in a single study with a limited sample size.

ReviewThe patient experience of patient-centered communication with nurses in the hospital setting: a qualitative systematic review protocol.
The objective of this systematic review is to synthesize the eligible evidence of patients' experience of engaging and interacting with nurses, in the medical-surgical ward setting.This review will consider the following questions: ⋯ Communication is a way in which humans make sense of the world around them. Communication takes place as an interactive two-way process or interaction, involving two or more people and can occur by nonverbal, verbal, face-to-face or non-face-to-face methods. Effective communication is described to occur when the sender of a message sends their message in a way that conveys the intent of their message and then is understood by the receiver of the message. As a result of the communication from both the sender and the receiver of the message a shared meaning is created between both parties.Communication can therefore be viewed as a reciprocal process. In the health care literature the terms communication and interaction are used interchangeably.Communication failures between clinicians are the most common primary cause of errors and adverse events in health care. Communication is a significant factor in patient satisfaction and complaints about care. Communication plays an integral role in service quality in all service professions including health care professions.Within healthcare, quality care has been defined by the Institute of Medicine as 'care that is safe, effective, timely, efficient, equitable and patient-centred'. Patient-centered care is defined as 'care that is respectful of and responsive to individual patient preferences, needs and values, and ensuring that patient's values guide all clinical decisions. Patient centered-care encompasses the 'individual experiences of a patient, the clinical service, the organizational and the regulatory levels of health care'. At the individual patient level, patient-centered care is care that is 'provided in a respectful manner, assures open and ongoing sharing of useful information in an ongoing manner and supports and encourages the participation of patients and their families'. Healthcare organizations that are patient-centered engage patients as partners and hold human interactions as a pillar of their service.The deepening evidence base for principles and practice of patient-centered care has resulted in increasing recognition of, and greater focus on, the engagement of patients, and the value and benefit of patient engagement. Contemporary healthcare policy across the globe increasingly supports the engagement of patients as partners in all aspects of their own health care and also in systemic quality improvement. In 2005, the World Health Organization's (WHO) World Alliance for Patient Safety established the Patients for Patient Safety program, to improve patient safety globally in collaboration with patient advocates across the world. As a global initiative, Patients for Patient Safety 'believes that safety will be improved if patients are placed at the center of care and included as full partners'.In 2011 the United States of America Department of Health and Human Services announced its commitment of one billion US dollars of federal funding under The Patient Protection and Affordable Care Act 2010 and launched the Partnership for Patients initiative. The Partnership for Patients public-private consortium, which focuses on patient safety improvements and draws membership from federal government agencies and over 8000 health care providing organizations and individuals, views patients 'as essential partners in improving safety and quality' and 'their participation as active members of their own healthcare team is an essential component of making healthcare safer and reducing readmission'.In Australia, as part of national health care reforms to improve access to care, the efficiency of care and public transparency of the performance and funding of health services, the Australian Health Ministers endorsed the 10 National Safety and Quality Health Service Standards (NSQHSS) in 2011 and the Australian Safety and Quality Goals for Health Care (The Goals) in 2012. The NSQHSS focus on partnerships with health consumers in their own care and treatment and also in health service planning, the design of care and service monitoring and evaluation. Standard 1 - Governance for Safety and Quality, and Standard 2 - Partnering with Consumers, are required to be integrated within all of the other eight Standards.With patient safety and quality being core to the delivery of care the Safety of Care, Appropriateness of Care and Partnering with Consumers goals have been identified as the three areas that will make up the goals over the next five years until 2017. The Australian Commission on Safety and Quality in Health Care, in providing further justification for the focus on these three areas, states:The third priority area of The Goals, Partnering with Consumers, reflects patient-centered care practice by ensuring 'that there are effective partnerships between consumers and healthcare providers and organizations at all levels of healthcare provision, planning and evaluation'. Specifically, 'Consumers and healthcare providers understand each other when communicating about care and treatment and health care organizations are health literate organizations''.As healthcare focuses on providing services that are patient-centered and methods to ensure this occurs, patients' voice and experience of health care provision is increasingly being sought from an organizational quality improvement perspective. Patients are being surveyed on their healthcare experience across interpersonal areas such as being provided the opportunity by their health professional to ask questions, the level of involvement in their own care and whether they were shown courtesy, treated with respect and listened to carefully by their health professional.Surveys of patients' satisfaction with their care are now being superseded by surveys of patient experiences of care. However, current methods used to collect and use information from patients about their care is often retrospective, provides inadequate real time data and is not effective in creating action to produce change at the individual patient level. Methods which focus on including the patient and their information in real-time are considered by many to be crucial to the advancement of improved health outcomes and the reduced costs that are required of health care to be sustainable. One such method is patient-centered communication.The nurse-patient interaction is a core component of nursing science and high quality nursing care. Fleisher et al. contend that 'the main intention of communication and interaction, in the health setting, is to influence the patient's health status or state of well-being'. As a profession, nursing predominately requires communicating with, and relating to, patients at the individual level. In the hospital setting nurses undertake many of their patient related duties in a face-to-face manner with the patient at the bedside and these moments can facilitate effective interaction to occur between the nurse and the patient, which is patient-centered. McCabe et al. state that patient-centered communication as "defined by Langewitz et al. as 'communication that invites and encourages the patient to participate and negotiate in decision-making regarding their own care'.''However, qualitative studies by McCabe and Wellard et al, highlighted that nurses interact with patients only when performing administrative or functional activities and nursing 'practice was predominately task-orientated'. The outcome of these studies are supported by Maurer et al. in their report on the tools and strategies available to support patient and family engagement in the hospital setting. Maurer et al. identified that current strategies 'are not attuned to patient and family member experiences of hospitalization' and that most tools and strategies were 'more reflective of health professional and hospital views and the organization of their work'. The report identified a gap in the initiation of engagement, which is not driven by the patients and families' needs and preferences as they occur but by the 'opportunities that the hospital makes available'.McCabe et al. also argue that nurses' attending behavior, that is their 'accessibility and readiness to listen to patients through the use of non-verbal communication' requires that they have the underpinning elements of 'genuineness, warmth and empathy' all of which are components of patient-centered communication. McCabe et al. observed that 'that nurses do not always communicate in a patient-centered way'.According to Fleischer et al. 'The listening behavior in the way of listening and asking actually is the beginning of the nurse-patient communication relationship' McCabe et al. state that the lack of recognition and support by healthcare organizations of the connection and subsequent importance of patient-centered communication in the provision of high quality care has promulgated a culture averse to patient centered communication and is a significant factor in reducing the value that nurses place on providing patient-centered communication to patients.It is apparent that tensions exist between service quality and patient-centered care principles and practice. The impact of this tension on care and the patient as an individual is reflected in the literature. McCabe et al. claim that the use of non-patient-centered types of communication can negatively affect a patient's sense of well-being and security. Horvey et al. detail patient and family member experiences of not being listened to by their health care providers and describe the resulting consequences to be as severe as the death of the patient during their hospital stay.
