Background: Contraceptive implants are one of the most effective contraceptive methods, providing a long duration of pregnancy protection and a high safety profile. Hence this method is suitable for optimizing the interpregnancy interval, especially for women undergoing abortion. Women who have had abortions are at high risk of rapid repeat pregnancies. Provision of effective contraception at the time of an abortion visit can be a key strategy to increase access and uptake of contraception. A review of the evidence was needed to evaluate progestin-releasing implants for immediate use at the time of abortion, including whether immediate placement impacts the effectiveness of medical abortion, which relies on antiprogestogens.
Objectives: To compare contraceptive implant initiation rates, contraceptive effectiveness, and adverse outcomes associated with immediate versus delayed insertion of contraceptive implants following abortion.
Selection criteria: We sought randomized controlled trials (RCTs) comparing immediate versus delayed insertion of contraceptive implant for contraception following abortion.
Background: Vertebral artery stenosis (narrowing of the vertebral artery) is an important cause of posterior circulation ischaemic stroke. Medical treatment (MT) e.g. controlling risk-factors and drug treatment, surgery, and endovascular treatment (ET) are the prevailing treatment strategies for symptomatic vertebral artery stenosis. ET consist s of percutaneous transluminal angioplasty (balloon catheter through the skin), with or without stenting. However, optimal management of people with symptomatic vertebral artery stenosis has not yet been established.
Objectives: To assess the safety and efficacy of percutaneous transluminal angioplasty, with or without stenting, combined with MT, compared to MT alone, in people with episodes of cerebral ischaemia due to vertebral artery stenosis.
Selection criteria: We included all randomised controlled trials (RCTs) that compared ET plus MT with MT alone in treating people aged 18 years or over with symptomatic vertebral artery stenosis. We included all types of ET modalities (e.g. angioplasty alone, balloon-mounted stenting, and angioplasty followed by placement of a self-expanding stent). MT included risk factor control, antiplatelet therapy, lipid-lowering therapy, and individualised management for people with hypertension or diabetes.
Background: Complex regional pain syndrome (CRPS) is a painful and disabling condition that usually manifests in response to trauma or surgery and is associated with significant pain and disability. CRPS can be classified into two types: type I (CRPS I) in which a specific nerve lesion has not been identified and type II (CRPS II) where there is an identifiable nerve lesion. Guidelines recommend the inclusion of a variety of physiotherapy interventions as part of the multimodal treatment of people with CRPS. This is the first update of the review originally published in Issue 2, 2016.
Objectives: To determine the effectiveness of physiotherapy interventions for treating pain and disability associated with CRPS types I and II in adults.
Selection criteria: We included randomised controlled trials (RCTs) of physiotherapy interventions compared with placebo, no treatment, another intervention or usual care, or other physiotherapy interventions in adults with CRPS I and II. Primary outcomes were pain intensity and disability. Secondary outcomes were composite scores for CRPS symptoms, health-related quality of life (HRQoL), patient global impression of change (PGIC) scales and adverse effects.
Background: Our March 2021 edition of this review showed thoracic imaging computed tomography (CT) to be sensitive and moderately specific in diagnosing COVID-19 pneumonia. This new edition is an update of the review.
Objectives: Our objectives were to evaluate the diagnostic accuracy of thoracic imaging in people with suspected COVID-19; assess the rate of positive imaging in people who had an initial reverse transcriptase polymerase chain reaction (RT-PCR) negative result and a positive RT-PCR result on follow-up; and evaluate the accuracy of thoracic imaging for screening COVID-19 in asymptomatic individuals. The secondary objective was to assess threshold effects of index test positivity on accuracy.
Selection criteria: We included diagnostic accuracy studies of all designs, except for case-control, that recruited participants of any age group suspected to have COVID-19. Studies had to assess chest CT, chest X-ray, or ultrasound of the lungs for the diagnosis of COVID-19, use a reference standard that included RT-PCR, and report estimates of test accuracy or provide data from which we could compute estimates. We excluded studies that used imaging as part of the reference standard and studies that excluded participants with normal index test results.
Background: Giant cell arteritis (GCA) is the most common form of systemic vasculitis in people older than 50 years of age. It causes granulomatous inflammation of medium- to large-sized vessels. Tocilizumab is a recombinant monoclonal antibody directed against interleukin-6 receptors (IL-6R).
Objectives: To assess the effectiveness and safety of tocilizumab, given alone or with corticosteroids, compared with therapy without tocilizumab for treatment of GCA.
Selection criteria: We included only randomized controlled trials (RCTs) that compared tocilizumab of any dosage regimen (alone or with corticosteroids) with therapy without tocilizumab that had a minimum follow-up of six months. Participants were at least 50 years of age, with biopsy-proven GCA or by large-vessel vasculitis by angiography, and met the American College of Rheumatology 1990 guidelines for GCA.
Background: Crohn's disease (CD) is an inflammatory bowel disease that causes inflammation and stricture, of any part of the mucosa and the gut wall. It forms skip lesions, sparing the areas in between the affected parts of the gastrointestinal tract. Crohn's disease could have one of three complications; fistula, intestinal obstruction due to stricture, or gastrointestinal inflammation presenting as severe diarrhoea. Stem cell therapy (SCT) is an innovative treatment that has been recently used in CD. The exact role of SCT in CD is still unclear. Stem cells modify the immunity of the patients or act as a "reset tool" for the immune system as in the case of systemically-injected stem cells, or regenerate the affected area of necrotic and inflammatory tissue as in the case of local injection into the lesion. Stem cells are a wide variety of cells including pluripotent stem cells or differentiated stem cells. The hazards range from rejection to symptomatic manifestations as fever or increase infection.
Objectives: The objective of this Cochrane systematic review is to assess the effects of stem cell transplantation compared to standard of care alone or with placebo on efficacy and safety outcomes in patients with refractory CD.
Selection criteria: We included only randomised controlled trials (RCTs) that assessed the effectiveness and safety of SCT in refractory CD versus standard care alone (control) or with placebo.
Background: Developments in ultrasound assessment of pregnancy has resulted in the increasing diagnosis of antenatal fetal issues. Many structural fetal conditions as well as complications associated with multiple pregnancies have the potential for in-utero treatment to improve both pregnancy and neonatal outcomes. Procedures such as laser ablation for twin-twin syndrome or cord occlusion for selective fetal termination require fetal immobilisation. Immobilisation of the fetus can occur through administration of medication to the mother or directly to the fetus. This improves procedural success and reduces the ongoing risk to the pregnancy. Evidence regarding the best medication and mode of delivery helps to ensure the optimal decision is made for both the mother and the fetus.
Objectives: To assess the effects of perioperative pharmacological interventions for fetal immobilisation during fetal surgery and invasive procedures on fetal, neonatal, and maternal outcomes.
Selection criteria: We included randomised controlled trials (RCTs) and quasi-RCTs (including published abstracts) which compared different classes of medication administered to the mother or fetus to allow in-utero procedures to be performed. We also included cluster-randomised trials but excluded cross-over trials.
Background: Abortion is common worldwide and increasingly abortions are performed at less than 14 weeks' gestation using medical methods, specifically using a combination of mifepristone and misoprostol. Medical abortion is known to be a painful process, but the optimal method of pain management is unclear. We sought to identify and compare pain management regimens for medical abortion before 14 weeks' gestation.
Objectives: Primary objective To determine if there is evidence of superiority of any particular pain relief regimen in the management of combination medical abortion (mifepristone + misoprostol) under 14 weeks' gestation (i.e. up to 13 + 6 weeks or 97 days). Secondary objectives To compare the rate of gastrointestinal side effects resulting from different methods of analgesia To compare the rate of complete abortion resulting from different methods of analgesia during medical abortion To determine if the induction-to-abortion interval is associated with different methods of analgesia To determine if any method of analgesia is associated with unscheduled contact with the care provider in relation to pain.
Selection criteria: We included randomised controlled trials (RCTs) and observational studies (non-randomised studies of interventions (NRSIs)) of any pain relief intervention (pharmacological and non-pharmacological) for mifepristone-misoprostol combination medical abortion of pregnancies less than 14 weeks' gestation.
Background: Pulmonary hypertension (PH) is an important cause of morbidity and mortality, which leads to a substantial loss of exercise capacity. PH ultimately leads to right ventricular overload and subsequent heart failure and early death. Although early detection and treatment of PH are recommended, due to the limited responsiveness to therapy at late disease stages, many patients are diagnosed at a later stage of the disease because symptoms and signs of PH are nonspecific at earlier stages. While direct pressure measurement with right-heart catheterisation is the clinical reference standard for PH, it is not routinely used due to its invasiveness and complications. Trans-thoracic Doppler echocardiography is less invasive, less expensive, and widely available compared to right-heart catheterisation; it is therefore recommended that echocardiography be used as an initial diagnosis method in guidelines. However, several studies have questioned the accuracy of noninvasively measured pulmonary artery pressure. There is substantial uncertainty about the diagnostic accuracy of echocardiography for the diagnosis of PH.
Objectives: To determine the diagnostic accuracy of trans-thoracic Doppler echocardiography for detecting PH.
Selection criteria: We included studies that evaluated the diagnostic accuracy of trans-thoracic Doppler echocardiography for detecting PH, where right-heart catheterisation was the reference standard. We excluded diagnostic case-control studies (two-gate design), studies where right-heart catheterisation was not the reference standard, and those in which the reference standard threshold differed from 25 mmHg. We also excluded studies that did not provide sufficient diagnostic test accuracy data (true-positive [TP], false-positive [FP], true-negative [TN], and false-negative [FN] values, based on the reference standard). We included studies that provided data from which we could extract TP, FP, TN, and FN values, based on the reference standard. Two authors independently screened and assessed the eligibility based on the titles and abstracts of records identified by the search. After the title and abstract screening, the full-text reports of all potentially eligible studies were obtained, and two authors independently assessed the eligibility of the full-text reports.
Background: An unprecedented number of people around the world are experiencing forced displacement due to natural or man-made events. More than 50% of refugees worldwide are children or adolescents. In addition to the challenges of settling in a new country, many have witnessed or experienced traumatic events. Therefore, refugee children and adolescents are at risk of developing mental health problems such as post-traumatic stress disorder, and require appropriate and effective support within communities.
Objectives: To assess the effectiveness and acceptability of community-based interventions (RCTs only) in comparison with controls (no treatment, waiting list, alternative treatment) for preventing and treating mental health problems (major depression, anxiety, post-traumatic stress disorder, psychological distress) and improving mental health in refugee children and adolescents in high-income countries.
Selection criteria: Studies of any design were eligible as long as they included child or adolescent refugees and evaluated a community-based mental health intervention in a high-income country. At a second stage, we selected randomised controlled trials.
Background: Substance use disorder (SUD) is the continued use of one or more psychoactive substances, including alcohol, despite negative effects on health, functioning, and social relations. Problematic drug use has increased by 10% globally since 2013, and harmful use of alcohol is associated with 5.3% of all deaths. Direct effects of music therapy (MT) on problematic substance use are not known, but it may be helpful in alleviating associated psychological symptoms and decreasing substance craving.
Objectives: To compare the effect of music therapy (MT) in addition to standard care versus standard care alone, or to standard care plus an active control intervention, on psychological symptoms, substance craving, motivation for treatment, and motivation to stay clean/sober.
Selection criteria: We included randomised controlled trials comparing MT plus standard care to standard care alone, or MT plus standard care to active intervention plus standard care for people with SUD.
Background: Social interaction and social communication are among the central areas of difficulty for autistic people. Music therapy uses music experiences and the relationships that develop through them to enable communication and expression, thus attempting to address some of the core problems of autistic people. Music therapy has been applied in autism since the early 1950s, but its availability to autistic individuals varies across countries and settings. The application of music therapy requires specialised academic and clinical training which enables therapists to tailor the intervention to the specific needs of the individual. The present version of this review on music therapy for autistic people is an update of the previous Cochrane review update published in 2014 (following the original Cochrane review published in 2006).
Objectives: To review the effects of music therapy, or music therapy added to standard care, for autistic people.
Selection criteria: All randomised controlled trials (RCTs), quasi-randomised trials and controlled clinical trials comparing music therapy (or music therapy alongside standard care) to 'placebo' therapy, no treatment, or standard care for people with a diagnosis of autism spectrum disorder were considered for inclusion.
Background: Hepatocellular carcinoma occurs mostly in people with chronic liver disease and ranks sixth in terms of global incidence of cancer, and third in terms of cancer deaths. In clinical practice, magnetic resonance imaging (MRI) is used as a second-line diagnostic imaging modality to confirm the presence of focal liver lesions suspected as hepatocellular carcinoma on prior diagnostic test such as abdominal ultrasound or alpha-fetoprotein, or both, either in surveillance programmes or in clinical settings. According to current guidelines, a single contrast-enhanced imaging study (computed tomography (CT) or MRI) showing typical hallmarks of hepatocellular carcinoma in people with cirrhosis is considered valid to diagnose hepatocellular carcinoma. The detection of hepatocellular carcinoma amenable to surgical resection could improve the prognosis. However, a significant number of hepatocellular carcinomas do not show typical hallmarks on imaging modalities, and hepatocellular carcinoma may, therefore, be missed. There is no clear evidence of the benefit of surveillance programmes in terms of overall survival: the conflicting results can be a consequence of inaccurate detection, ineffective treatment, or both. Assessing the diagnostic accuracy of MRI may clarify whether the absence of benefit could be related to underdiagnosis. Furthermore, an assessment of the accuracy of MRI in people with chronic liver disease who are not included in surveillance programmes is needed for either ruling out or diagnosing hepatocellular carcinoma.
Objectives: Primary: to assess the diagnostic accuracy of MRI for the diagnosis of hepatocellular carcinoma of any size and at any stage in adults with chronic liver disease. Secondary: to assess the diagnostic accuracy of MRI for the diagnosis of resectable hepatocellular carcinoma in adults with chronic liver disease, and to identify potential sources of heterogeneity in the results.
Selection criteria: Studies assessing the diagnostic accuracy of MRI for the diagnosis of hepatocellular carcinoma in adults with chronic liver disease, with cross-sectional designs, using one of the acceptable reference standards, such as pathology of the explanted liver and histology of resected or biopsied focal liver lesion with at least a six-month follow-up.
Background: Comprehensive Geriatric Assessment (CGA) is a multidimensional interdisciplinary diagnostic process focused on determining an older person's medical, psychological and functional capability in order to develop a co-ordinated and integrated care plan. CGA is not limited simply to assessment, but also directs a holistic management plan for older people, which leads to tangible interventions. While there is established evidence that CGA reduces the likelihood of death and disability in acutely unwell older people, the effectiveness of CGA for community-dwelling, frail, older people at risk of poor health outcomes is less clear.
Objectives: To determine the effectiveness of CGA for community-dwelling, frail, older adults at risk of poor health outcomes in terms of mortality, nursing home admission, hospital admission, emergency department visits, serious adverse events, functional status, quality of life and resource use, when compared to usual care.
Selection criteria: We included randomised trials that compared CGA for community-dwelling, frail, older people at risk of poor healthcare outcomes to usual care in the community. Older people were defined as 'at risk' either by being frail or having another risk factor associated with poor health outcomes. Frailty was defined as a vulnerability to sudden health state changes triggered by relatively minor stressor events, placing the individual at risk of poor health outcomes, and was measured using objective screening tools. Primary outcomes of interest were death, nursing home admission, unplanned hospital admission, emergency department visits and serious adverse events. CGA was delivered by a team with specific gerontological training/expertise in the participant's home (domiciliary Comprehensive Geriatric Assessment (dCGA)) or other sites such as a general practice or community clinic (community Comprehensive Geriatric Assessment (cCGA)).
Background: Chronic obstructive pulmonary disease (COPD) is a common, preventable and treatable health condition. COPD is associated with substantial burden on morbidity, mortality and healthcare resources.
Objectives: To review existing evidence for educational interventions delivered to health professionals managing COPD in the primary care setting.
Selection criteria: We included randomised controlled trials (RCTs) and cluster-RCTs. Eligible studies tested educational interventions aimed at any health professionals involved in the management of COPD in primary care. Educational interventions were defined as interventions aimed at upskilling, improving or refreshing existing knowledge of health professionals in the diagnosis and management of COPD.
Background: Management of the open abdomen is a considerable burden for patients and healthcare professionals. Various temporary abdominal closure techniques have been suggested for managing the open abdomen. In recent years, negative pressure wound therapy (NPWT) has been used in some centres for the treatment of non-trauma patients with an open abdomen; however, its effectiveness is uncertain.
Objectives: To assess the effects of negative pressure wound therapy (NPWT) on primary fascial closure for managing the open abdomen in non-trauma patients in any care setting.
Selection criteria: We included all randomised controlled trials (RCTs) that compared NPWT with any other type of temporary abdominal closure (e.g. Bogota bag, Wittmann patch) in non-trauma patients with open abdomen in any care setting. We also included RCTs that compared different types of NPWT systems for managing the open abdomen in non-trauma patients.
Background: Although many people infected with SARS-CoV-2 (severe acute respiratory syndrome coronavirus-2) experience no or mild symptoms, some individuals can develop severe illness and may die, particularly older people and those with underlying medical problems. Providing evidence-based interventions to prevent SARS-CoV-2 infection has become more urgent with the spread of more infectious SARS-CoV-2 variants of concern (VoC), and the potential psychological toll imposed by the coronavirus disease 2019 (COVID-19) pandemic.   Controlling exposures to occupational hazards is the fundamental method of protecting workers. When it comes to the transmission of viruses, such as SARS-CoV-2, workplaces should first consider control measures that can potentially have the most significant impact. According to the hierarchy of controls, one should first consider elimination (and substitution), then engineering controls, administrative controls, and lastly, personal protective equipment (PPE).
Objectives: To assess the benefits and harms of interventions in non-healthcare-related workplaces to reduce the risk of SARS-CoV-2 infection relative to other interventions, or no intervention.
Selection criteria: We included randomised control trials (RCT) and planned to include non-randomised studies of interventions. We included adult workers, both those who come into close contact with clients or customers (e.g. public-facing employees, such as cashiers or taxi drivers), and those who do not, but who could be infected by co-workers. We excluded studies involving healthcare workers. We included any intervention to prevent or reduce workers' exposure to SARS-CoV-2 in the workplace, defining categories of intervention according to the hierarchy of hazard controls, i.e. elimination; engineering controls; administrative controls; personal protective equipment.
Background: Pulmonary embolism (PE) is a common life-threatening cardiovascular condition, with an incidence of 23 to 69 new cases per 100,000 people each year. For selected low-risk patients with acute PE, outpatient treatment might provide several advantages over traditional inpatient treatment, such as reduction of hospitalisations, substantial cost savings, and improvements in health-related quality of life. This is an update of an earlier Cochrane Review.
Objectives: To assess the effects of outpatient versus inpatient treatment in low-risk patients with acute PE.
Selection criteria: We included randomised controlled trials (RCTs) of outpatient versus inpatient treatment of adults (aged 18 years and over) diagnosed with low-risk acute PE.
