The effectiveness of non-pharmacological sleep interventions for improving inpatient sleep in hospital: A systematic review and meta-analysis.

BACKGROUND: Sleep disturbance is common in hospital. The hospital environment can have a negative impact on sleep quality, through factors such as noise, light, temperature, and nursing care disruptions. Poor sleep can lead to delays in recovery, wound healing, and increase risk of post-operative infection. METHODS: We conducted a systematic review evaluating the effectiveness of non-pharmacological sleep interventions for improving inpatient sleep. The primary outcome was sleep quality, the secondary outcome was length of hospital stay, the harm outcome was adverse events. MEDLINE, Embase, CINAHL, PsycINFO and the Cochrane Library were searched from inception to 17th February 2022. Meta-analysis was conducted using a fixed effects model, with narrative synthesis for studies with no useable data. Risk of bias was assessed with the Cochrane tool. RESULTS: 76 studies identified with 5375 people randomised comparing 85 interventions. Interventions focused on physical sleep aids (n = 26), relaxation (n = 25), manual therapy (n = 12), music (n = 9), psychological therapy (n = 5), light therapy (n = 3), sleep protocols (n = 2), milk and honey (n = 1), exercise (n = 1), and nursing care (n = 1). In meta-analysis, medium to large improvements in sleep quality were noted for sleep aids, relaxation, music, and manual therapies. Results were generally consistent in studies at lower risk of bias. Length of hospital stay and adverse events were reported for some studies, with benefit in some trials but this was not consistent across all interventions. CONCLUSIONS: Physical sleep aids, relaxation, manual therapy and music interventions have a strong evidence base for improving inpatient sleep quality. Research is needed to evaluate how to optimise interventions into routine care.

Development of a novel intervention to improve sleep and pain in patients undergoing total knee replacement.

BACKGROUND: Up to 20% of patients experience long-term pain and dissatisfaction after total knee replacement, with a negative impact on their quality of life. New approaches are needed to reduce the proportion of people to go on to experience chronic post-surgical pain. Sleep and pain are bidirectionally linked with poor sleep linked to greater pain. Interventions to improve sleep among people undergoing knee replacement offer a promising avenue. Health beliefs and barriers to engagement were explored using behaviour change theory. This study followed stages 1-4 of the Medical Research Council's guidance for complex intervention development to develop a novel intervention aimed at improving sleep in pre-operative knee replacement patients. METHODS: Pre-operative focus groups and post-operative telephone interviews were conducted with knee replacement patients. Before surgery, focus groups explored sleep experiences and views about existing sleep interventions (cognitive behavioural therapy for insomnia, exercise, relaxation, mindfulness, sleep hygiene) and barriers to engagement. After surgery, telephone interviews explored any changes in sleep and views about intervention appropriateness. Data were audio-recorded, transcribed, anonymised, and analysed using framework analysis. RESULTS: Overall, 23 patients took part, 17 patients attended pre-operative focus groups, seven took part in a post-operative telephone interview, and one took part in a focus group and interview. Key sleep issues identified were problems getting to sleep, frequent waking during the night, and problems getting back to sleep after night waking. The main reason for these issues was knee pain and discomfort and a busy mind. Participants felt that the sleep interventions were generally acceptable with no general preference for one intervention over the others. Views of delivery mode varied in relation to digital move and group or one-to-one approaches. CONCLUSION: Existing sleep interventions were found to be acceptable to knee replacement patients. Key barriers to engagement related to participants' health beliefs. Addressing beliefs about the relationship between sleep and pain and enhancing understanding of the bidirectional/cyclical relationship could benefit engagement and motivation. Individuals may also require support to break the fear and avoidance cycle of pain and coping. A future intervention should ensure that patients' preferences for sleep interventions and delivery mode can be accommodated in a real-world context.

Value, transparency, and inclusion: A values-based study of patient involvement in musculoskeletal research.

BACKGROUND: Patient and public involvement work (PPI) is essential to good research practice. Existing research indicates that PPI offers benefits to research design, conduct, communication, and implementation of findings. Understanding how PPI works and its value helps to provide information about best practice and highlight areas for further development. This study used a values-based approach to reporting PPI at a Research Unit focused on musculoskeletal conditions within a UK medical school. METHODS: The study was conducted between October 2019 and January 2020 using Gradinger's value system framework as a theoretical basis. The framework comprises three value systems each containing five clusters. All PPI members and researchers who had attended PPI groups were invited to participate. Participants completed a structured questionnaire based on the value system framework; PPI members also provided further information through telephone interviews. Data were deductively analysed using a framework approach with data mapped onto value systems. RESULTS: Twelve PPI members and 17 researchers took part. Views about PPI activity mapped onto all three value systems. PPI members felt empowered to provide their views, and that their opinions were valued by researchers. It was important to PPI members that they were able to 'give back' and to do something positive with their experiences. Researchers would have liked the groups to be more representative of the wider population, patients highlighted that groups could include more younger members. Researchers recognised the value of PPI, and the study highlighted areas where researchers members might benefit from further awareness. CONCLUSIONS: Three areas for development were identified: (i) facilitating researcher engagement in training about the value and importance of PPI in research; (ii) support for researchers to reflect on the role that PPI plays in transparency of healthcare research; (iii) work to further explore and address aspects of diversity and inclusion in PPI.

Exploring the acceptability of using low-friction bedding for patients with burns: Qualitative results from the SILKIE study.

BACKGROUND: Skin grafts following deep burns are needed to ensure healing. Grafts that fail and require re-grafting cause significant distress to patients and additional costs for the NHS. Shearing, which leads to graft loss, may be reduced through the use of low-friction bedding. A feasibility study was conducted to assess proof of concept for the use of low-friction bedding for patients with burns. Patient, parent and staff views on the acceptability of this material were explored through semi-structured interviews. METHOD: Patient views were gathered through telephone interviews (n=17; 11 adult patients and 6 parents of child patients). One patient completed the questionnaire in written form because of hearing difficulties. Staff views were gathered at two time points: at the start of the study through open-ended questionnaires (n=20) and at the end of the study through focus group (n=12) and telephone interviews (n=3). Data were analysed using framework analysis. RESULTS: Three themes were identified describing both patient and staff views of the sheets: Slippery feel of the sheets; leaking wounds and sheet changes; and movement and friction. Overall patients' views of the sheets were positive; they were comfortable to use the sheets and experienced reduced pain and itching. However, issues related to the slipperiness were highlighted. Staff views were largely negative because of difficulty in use, lack of absorbency, and increased workload. CONCLUSION: The use of low-friction bedding is acceptable to patients undergoing a skin graft following a burn injury; however, problems related to sliding down the bed and soiling of sheets need addressing. Staff were supportive of the concept of low-friction bedding; however, they reported significant challenges in day-to-day use of sheets. Low-friction bedding presents a promising alternative to standard cotton sheets for patients with burns and those at risk of pressure sores; however, further work is needed to address current challenges in use.

Outcome reporting in bariatric surgery: an in-depth analysis to inform the development of a core outcome set, the BARIACT Study.

Outcome reporting in bariatric surgery needs a core outcome set (COS), an agreed minimum set of outcomes reported in all studies of a particular condition. The aim of this study was to summarize outcome reporting in bariatric surgery to inform the development of a COS. Outcomes reported in randomized controlled trials (RCTs) and large non-randomized studies identified by a systematic review were listed verbatim and categorized into domains, scrutinizing the frequency of outcome reporting and uniformity of definitions. Ninety studies (39 RCTs) identified 1,088 separate outcomes, grouped into nine domains with most (n = 920, 85%) reported only once. The largest outcome domain was 'surgical complications', and overall, 42% of outcomes corresponded to a theme of 'adverse events'. Only a quarter of outcomes were defined, and where provided definitions, which were often contradictory. Percentage of excess weight loss was the main study outcome in 49 studies, but nearly 40% of weight loss outcomes were heterogeneous, thus not comparable. Outcomes of diverse bariatric operations focus largely on adverse events. Reporting is inconsistent and ill-defined, limiting interpretation and comparison of published studies. Thus, we propose and are developing a COS for the surgical treatment of severe and complex obesity.

The heavy eye phenomenon: orthoptic and ophthalmic characteristics.

A series is presented of nine patients who demonstrate the heavy eye phenomenon. Illustrations of these patients show the salient features of the phenomenon, including hypotropia, exotropia and pseudoproptosis. The condition is summarized and the pathogenesis of the eye and lid positions are discussed. The indications for surgery and some examples with results are shown. The correct diagnosis may prevent unnecessary investigation of pseudoproptosis and pseudo third-nerve palsy.

The role of streptococcal infection in the initiation of guttate psoriasis.

BACKGROUND AND DESIGN: Although the association between streptococcal infection and guttate psoriasis is well known, to date there has been little information on whether only limited groups and/or serotypes of beta-hemolytic streptococci are involved. One hundred eleven patients with a sudden onset or deterioration of psoriasis were investigated for evidence of streptococcal infection. Of these patients, 34 had acute guttate psoriasis, 30 had a guttate flare of chronic psoriasis, 37 had chronic plaque psoriasis, and 10 had other types of psoriasis. RESULTS: Serologic evidence of recent streptococcal infection was present in 19 (58%) of 33 patients with acute guttate psoriasis compared with seven (26%) of 27 patients with guttate exacerbations of chronic psoriasis. Streptococcus pyogenes was isolated from 19 (17%) of all 111 patients (9 [26%] of 34 with acute guttate psoriasis, four [13%] of 30 with guttate exacerbations of chronic psoriasis, and five [14%] of 37 patients with chronic psoriasis) compared with seven (7%) of 101 of a control population of patients being seen for treatment of viral warts. Other beta-hemolytic streptococci were found with equal frequency in the study and control populations. Thirteen isolates of 10 different streptococcal serotypes were obtained from the 64 patients with guttate psoriasis. These serotypes were similar in distribution and prevalence to those present in the local community. CONCLUSIONS: This study confirms the strong association between prior infection with S pyogenes and guttate psoriasis but suggests that the ability to trigger guttate psoriasis is not serotype specific.

Macrophotography of the eyes: a technique for eyelid retraction.

It is important when photographing ocular movements or the bulbar conjunctiva that the full visualizations of the eye positions can be seen. This will require the upper eyelids to be retracted. The most common method is the use of fingers to retract the eyelids. A much improved technique is described using either cotton wool buds or orange sticks. It is simple and painless and makes the photographs superior in quality.

Pulmonary infection with Nocardia caviae in a patient with diabetes mellitus and liver cirrhosis.

The first reported case of pulmonary infection with Nocardia caviae in Britain occurred in a 67 year old woman, in whom diabetes mellitus and liver cirrhosis probably contributed to impaired cell mediated immunity. She was successfully treated with gentamicin 60 mg eight hourly and sulphadimidine 500 mg six hourly for six months and then with sulphadimidine 2 g/day for a further three months. When Nocardia caviae is isolated from the sputum of a patient with chronic respiratory infection and fever, effective treatment should be started promptly.

A comparison of the clinico-pathological features with stool pathogens in patients hospitalised with the symptom of diarrhoea.

The clinico-pathological features of 515 adult patients admitted to a major Regional Infectious Diseases Unit in United Kingdom with the symptom complex of diarrhoea were compared to the pathogens detected in their stool specimens. Routine clinical examination supported by basic pathological and laboratory investigations identified 138 (28%) in whom the cause of diarrhoea was extragastrointestinal or non-infectious gastrointestinal. Of the 351 patients (72%) with infectious gastroenteritis 72 (21%) had campylobacter, 59 (17%) had salmonella (22% bacteraemic) and 16 (5%) shigella. Clostridium difficile toxin accounted for a further 15 (4%)--antibiotics had been the antecedent cause in only one half of these. Routine microscopical examination of the faeces for red and white cells distinguished many with "culture positive" diarrhoea from those with "culture negative" infectious diarrhoea. Although there are no clinico-pathological features which are unique to a particular pathogen and unequivocally suggest a particular pathogen, certain features did tend to present more often in association with particular microorganisms, and this knowledge may suggest a bacterial diagnosis whilst awaiting the definitive results of stool microbiology. These features include prior antimicrobial therapy with positive sigmoidoscopical/histological features: Cl. difficile; protracted diarrhoea in elderly severely dehydrated patients: salmonellosis; foreign travel in males with bloody diarrhoea: shigellosis; abdominal pain in younger patients with a small degree of vomiting: campylobacteriosis. Early diagnosis may then prove useful in rationalizing initial therapy, particularly the appropriate use of antimicrobials.

Double-blind placebo-controlled trial of erythromycin in the treatment of clinical campylobacter infection.

In a double-blind placebo-controlled trial in patients hospitalized with campylobacter infection, erythromycin lessened pain and curtailed the carriage state but otherwise did not alter the natural course of the illness, which proved to be a short-lived, self-limiting one, even in this selected group of hospitalized patients; the majority had become asymptomatic by the time of the bacteriological diagnosis. The rarity of bacteraemia is highlighted by the study.
