ObjectivesPatients often suffer from disturbed sleep in hospital. Poor-quality sleep in hospitalised patients has been associated with significant morbidity and pharmacological sleep aids are often prescribed. The objective of this systematic review is to evaluate the comparative efficacy and safety of pharmacological interventions used for sleep in hospitalised patients.Setting/participantsWe searched MEDLINE, Embase, the Cochrane database and grey literature for prospective studies that evaluated sleep in hospitalised adults after a pharmacological intervention.Primary and secondary outcome measuresTwo reviewers assessed studies for inclusion and extracted data for efficacy outcomes, including sleep efficiency, sleep latency, sleep fragmentation and objectively measured sleep stage distribution. Risk of bias was assessed and meta-analyses were planned contingent upon homogeneity of the included studies.ResultsAfter screening 1920 citations, 15 studies involving 861 patients were included. Medications studied included benzodiazepines, nonbenzodiazepine sedatives, melatonin, propofol and dexmedetomidine. Five studies were deemed to be of high quality. Heterogeneity and variable outcome reporting precluded meta-analysis in most cases. No consistent trends with respect to sleep efficiency, quality or interruptions were observed identifying a drug or drug class as superior to another or no treatment. Benzodiazepines appeared to be better than no treatment with respect to sleep latency, but this was not consistently demonstrated across all studies. Sleep stage distribution shows that sleep in hospital is dominated by stages N1 and N2.ConclusionsThere is insufficient evidence to suggest that pharmacotherapy improves the quality or quantity of sleep in hospitalised patients suffering from poor sleep. No drug class or specific drug was identified as superior even when compared to placebo or no treatment. Although 15 studies were included, the quality of evidence was limited by their quality and size. Larger, better-designed trials in hospitalised adults are needed.
Objective This overview of reviews aims to map and compare of objectives, methods, and findings of existing systematic reviews to develop a greater understanding of the information available about prolonged beta-lactam infusions in hospitalized patients with infection. Design Overview of systematic reviews. Data sources Medline, Embase, PROSPERO and the Cochrane Library were systematically searched from January, 1990 to June, 2019 using a peer reviewed search strategy. Grey literature was also searched for relevant reviews. Eligibility criteria for selecting reviews Systematic reviews were sought that compared two or more infusion strategies for intravenous beta-lactam antimicrobials and report clinical cure or mortality. Populations of included reviews were restricted to hospitalized patients with infection, without restrictions on age, infection type, or disease. Data extraction and analysis Abstract screening, data extraction, quality and risk of bias assessment were conducted by two independent reviewers. Overlap between reviews was assessed using a modified corrected covered area. Overview findings are reported in accordance with Cochrane’s recommendation for overview conduct. Clinical outcomes extracted included survival, clinical cure, treatment failure, microbiological cure, length of stay, adverse events, cost, and emergence of resistance. Results The search strategy identified 3327 unique citations from which 21 eligible reviews were included. Reviews varied by population, intervention and outcomes studied. Between reviews, overlap of primary studies was generally high, methodologic quality generally low and risk of bias variable. Nine of 14 reviews that quantitatively evaluated mortality and clinical cure identified a benefit with prolonged infusions of beta lactams when compared with intermittent infusions. Evidence of mortality and clinical cure benefit was greater among critically ill patients when compared to less sick patients and lower in randomized controlled trials when compared with observational studies. Conclusions Findings from our review demonstrate a consistent and reproducible lack of harm with prolonged infusions of beta-lactam antibiotics with variability in effect size and significance of benefits. Despite 21 systematic reviews addressing prolonged infusions of beta-lactams, this overview supports the continued need for a definitive systematic review given variability in populations, interventions and outcomes in the current systematic reviews. Subsequent systematic reviews should have more rigorous and transparent methods, only include RCTs and evaluate the proposed benefits found in various subgroup-analyses—i.e. high risk of mortality.

A survey of 390 patients aged over 65 with fractured femurs showed that nearly all the fractures that had been caused by nocturnal falls had occurred among the many patients who were still taking barbiturate hypnotics. Barbiturates were also strongly associated with a history of frequent falls. Barbiturates are still prescribed surprisingly often for the elderly. An analysis of 1622 elderly patients referred to a geriatric clinic in Nottingham showed that 41% were taking barbiturates in 1973. By 1976 this figure had actually increased to 51%, despite the substantial campaign against barbiturate prescribing. This campaign thus appears to have made little or no impact on prescriptions for the elderly in at least one large town. The dangers of barbiturates may well need constant reemphasis.
In a study of factors associated with death from bronchial asthma in hospital 53 patients were investigated. Typically the fatal attack persisted for several days before admission to hospital and normally occurred in patients with a long history of asthma. The patient or doctor often underestimated the severity of the attack. On admission most patients were severely ill, and over a third died within 24 hours. Peak flow rate and blood gases were rarely measured. Corticosteroid treatment was often underused, and patients rarely received assisted ventilation before death. Infection played a part in 14 deaths, five of them associated with assisted ventilation. Admitting asthmatics to a special respiratory ward with facilities for standardised assessment and treatment and introducing a self-admission service may help to prevent some of these deaths. Methods Data on every death in hospital in the Cardiff area mentioning "asthma" were collected shortly after the death as detailed previously.'
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
