Evaluation of a health trainer-led service for people with knee, hip and back pain.

AIMS: Chronic knee, hip and back pain is extremely prevalent. Management guidelines emphasise maintaining physical activity and healthy weight to reduce pain and improve physical and mental wellbeing. Unfortunately, few people receive support to make lifestyle changes. We evaluated whether a health trainer-led 'joint pain advice' (JPA) service delivering person-centred lifestyle coaching was feasible, acceptable and effective for people with knee, hip and back pain. METHODS: Feasibility of delivering a JPA service was assessed by documenting whether the health trainers could deliver JPA and its uptake. Nine health trainers delivered JPA. Participants were offered up to four appointments. At each appointment, health trainers gave people information about their condition, co-developed care plans, suggested self-management strategies and used behavioural change techniques (motivational interviewing, goal-setting and action planning) to increase physical activity and reduce body weight. Pain, function, physical activity and body mass index (BMI) were collected at baseline, 3 weeks, 6 weeks and 6 months. Focus groups captured people's opinions of the service's effectiveness, acceptability and usefulness. RESULTS: Of the 105 people who enquired about JPA, 85 (81%) used the service, after which their physical activity and function improved, and pain, use of analgesia and BMI decreased. They felt more knowledgeable and better motivated to adopt and maintain healthier behaviours. They attributed these improvements to the JPA service, because of its better consultations and collaborative holistic approach. Only a minority attended all four appointments because they felt they received sufficient advice from the initial appointments. The health trainers gained knowledge and skills to support clients with musculoskeletal conditions. CONCLUSIONS: Using a holistic, patient-centred approach, health trainers can deliver lifestyle advice to people with chronic knee, hip or back pain safely, effectively and efficiently. The service was popular with recipients and health trainers, and helped people adopt healthier lifestyles that lead to reduced pain and other clinical improvements.

Successful termination of sustained transmission of resident MRSA following extensive NICU refurbishment: an intervention study.

BACKGROUND: Neonatal sepsis is a leading cause of morbidity and mortality in neonatal units worldwide. Meticillin-resistant Staphylococcus aureus (MRSA) has become a leading causative pathogen. Many neonatal units experience endemic colonization and infection of their infants, which is often very challenging to successfully eradicate. AIM: To assess the impact of neonatal unit refurbishment and redesign on endemic MRSA colonization and infection. METHODS: A retrospective review was carried out over an eight-year period in a 14-cot, level 2-3 neonatal unit in University Hospital Galway, a large university teaching hospital in the West of Ireland. Surveillance, colonization, and infection data for a four-year period pre and four-year period post neonatal unit refurbishment are described. Clinical and microbiological data were collected on all MRSA-colonized and -infected infants between 2008 and 2015. Molecular typing data are available for MRSA isolates. An interrupted time-series design was used, with unit refurbishment as the intervention. FINDINGS: Our neonatal unit had a pattern of sustained transmission of endemic resident MRSA strains which we could not eradicate despite repeated standard infection control interventions. Complete unit refurbishment led to successful termination of sustained transmission of these strains. Colonization decreased and no infants were actively infected post refurbishment of the unit. CONCLUSION: We report successful termination of sustained transmission of endemic strains of MRSA from our neonatal unit following complete unit redesign and refurbishment.

Computer network for a diagnostic virology laboratory.

A data base for a large diagnostic virology laboratory is described. The system uses a network of personal computers. It allows the entry, long-term storage, and subsequent retrieval of specimen and patient records (comprising personal identifiers and specimen and result information), and hard-copy results reporting. Sited entirely within the laboratory, the network is not connected to a modem. Within the laboratory there is restricted access to human immunodeficiency virus test results to guarantee patient confidentiality. Retention of a hard-copy of specimen request cards ensures the availability of the original clinical information. The data base is copied on a second file server to facilitate searches, and daily streaming onto magnetic tape provides system protection in the event of hard disc failure. Matching of old and new patient records is done by surname, date of birth, and sex, and therefore duplicate records accumulate when patient names are misspelt on specimen request forms. The system requires further development to speed searches of the data base and to achieve automatic generation of laboratory worksheets. Future goals are the replacement of hard-copy records of clinical information and hard-copy reporting with on-line access to hospital data bases and on-line requesting by and reporting to the clinician.

Low-dose intrathecal diamorphine analgesia following major orthopaedic surgery.

In a randomized double-blind study we examined the effect of adding diamorphine 0.25 mg and 0.5 mg to intrathecal bupivacaine anaesthesia for major orthopaedic surgery. Duration of postoperative analgesia was considerably greater in patients given either doses of intrathecal diamorphine than in a control group of patients given bupivacaine alone (P less than 0.001). However, there was no significant difference between the two diamorphine doses (0.25 mg and 0.5 mg), each providing prolonged analgesia (10.8 and 9.9 h, respectively). Although there was no evidence of late respiratory depression, the frequency of adverse effects, in particular urinary retention, nausea and vomiting, was high in both groups receiving intrathecal diamorphine.

Effect of the addition of adrenaline to extradural diamorphine analgesia after caesarean section.

In a randomized double-blind study the effect of the addition of adrenaline to extradural diamorphine was assessed in 54 patients after Caesarean section. Patients received extradural diamorphine 5 mg in saline 10 ml with or without adrenaline 1 in 200,000 for postoperative pain relief. Analgesia was profound and of rapid onset in both groups. Duration of analgesia was greater in the adrenaline group (time to next analgesia 12.51 +/- 0.94 h, mean +/- SEM), than in the saline group (9.87 +/- 0.98 h) (P = 0.057). Analgesia was also more consistent in the adrenaline group, with 77% of patients having more than 8 h of good analgesia compared with 48% in the saline group (P less than 0.05). Plasma morphine concentrations, measured in 12 patients, were lower, although not significantly so, in the adrenaline group and mean time to peak concentration markedly delayed. No serious side effects were observed, but there was a higher incidence of vomiting in the adrenaline group.

Correlation of netilmicin agar dilution and disk diffusion susceptibilities.

A study of 283 isolates of gram-negative bacilli revealed a good correlation (r = -0.74) between disk diffusion zones of inhibition and agar dilution minimal inhibitory concentrations. Regression analysis suggested that strains with zone sizes =/<11 mm should be considered resistant, but 34 of 45 strains resistant by minimal inhibitory concentration (including 27 strains of Pseudomonas aeruginosa) would have been called susceptible using this break point.

Outbreak of food-poisoning caused by Salmonella virchow in spit-roasted chicken.

Salmonella virchow food-poisoning acquired from eating chicken caused illness in at least 50 people who attended a tennis club function in Liverpool, and in many other people in the Merseyside area. In some cases the illness was severe, with positive blood cultures, and 35 people were admitted to hospital.The source of infection was a retail shop which received deep-frozen chickens already contaminated with S. virchow from a packing-station in Cheshire. These chickens were spit-roasted after inadequate thawing and subsequently handled under unhygienic conditions. The result was a massive build-up of salmonella contamination in the shop and in the chicken portions sold.S. virchow was isolated from over 160 patients and contacts in the Merseyside area during the outbreak and many continued to excrete the organism in the faeces after four months. Antibiotic treatment was not recomended because there was no evidence that it shortened the duration of excretion.A high rate of contamination of chickens from a packing-station by a salmonella type capable of causing serious disease in man is clearly a public health problem which cannot be ignored.The use of rotary spits for roasting chickens requires thorough investigation and appraisal, because as operated at present they evidently constitute a public health hazard.
