Assessment of a United States pharmaceutical care model for nursing homes in the United Kingdom

Objective

To assess the suitability of an American model of pharmaceutical care for nursing home residents (The Fleetwood model) for application in nursing homes in the United Kingdom.

Method

Pharmacists (those from a hospital setting or involved in prescribing support), general practitioners, nursing home managers and advocates for older people were invited to participate in semi-structured interviews or focus groups. The American Fleetwood model was explained to all participants who were asked for their views and opinions on how such a model could be adapted for use in the UK setting. All interviews and focus groups were tape-recorded, transcribed verbatim and analysed using the framework method.

Main outcome measure

An adapted model of pharmaceutical care for use in UK nursing homes.

Results

There was general concern about prescribing in nursing homes, particularly in relation to psychoactive drugs. All participants were supportive of the proposed model of care and endorsed the greater involvement of pharmacists. However, participants also recognised that unlike pharmacists in the US nursing home setting for which the Fleetwood model had been developed, pharmacists implementing this approach in the UK would face major challenges in relation to access to records (medical and medication), prescribers and residents.

Conclusion

The findings highlighted the key elements of access which will need to be considered if this model of pharmaceutical care is to be applied to nursing home residents in the UK.

Impact of findings on practice

The model has been revised to take account of the challenges relating to access and will be tested in a randomised controlled trial.

     

Vasodilator agents and supracollicular transection fail to inhibit cortical spreading depression in the cat

It remains an open question as to whether cortical spreading depression (CSD) is the pathophysiological correlate of the neurological symptoms in migraine with aura. In the experimental animal, CSD is an electrophysiological phenomenon mainly mediated via NMDA receptors. However, according to case reports in humans, visual aura in migraine can be alleviated by vasodilator substances, such as amyl nitrite and isoprenaline. There is also circumstantial evidence that brainstem nuclei (dorsal raphe nucleus and locus coeruleus) may play a pivotal role in the initiation of aura. In this study, CSD was elicited in alpha-chloralose anesthetized cats by cortical needle stab injury and monitored by means of laser Doppler flowmetry. Topical application of isoprenaline (0.1-1%) and amyl nitrite (0.05%) onto the exposed cortex had no effect on the elicitation or propagation of CSD. Also, after supracollicular transection, subsequent CSDs showed no differences in the speed of propagation and associated flow changes. We conclude from these data that--given CSD probably exists in humans during migraine--spreading neurological deficits during migraine aura are independent of brainstem influence and have a primarily neuronal rather than vascular mechanism of generation.     

Diffuse tibiofemoral cartilage change prior to the development of accelerated knee osteoarthritis: Data from the osteoarthritis initiative

We compared the spatial distribution of tibiofemoral cartilage change between individuals who will develop accelerated knee osteoarthritis (KOA) versus typical onset of KOA prior to the development of radiographic KOA. We conducted a longitudinal case–control analysis of 129 individuals from the Osteoarthritis Initiative. We assessed the percent change in tibiofemoral cartilage on magnetic resonance images at 36 informative locations from 2 to 1 year prior to the development of accelerated (n = 44) versus typical KOA (n = 40). We defined cartilage change in the accelerated and typical KOA groups at 36 informative locations based on thresholds of cartilage percent change in a no KOA group (n = 45). We described the spatial patterns of cartilage change in the accelerated KOA and typical KOA groups and performed a logistic regression to determine if diffuse cartilage change (predictor; at least half of the tibiofemoral regions demonstrating change in multiple informative locations) was associated with KOA group (outcome). There was a non‐significant trend that individuals with diffuse tibiofemoral cartilage change were 2.2 times more likely to develop accelerated knee OA when compared with individuals who develop typical knee OA (OR [95% CI] = 2.2 [0.90–5.14]. Adults with accelerated or typical KOA demonstrate heterogeneity in spatial distribution of cartilage thinning and thickening. These results provide preliminary evidence of a different spatial pattern of cartilage change between individuals who will develop accelerated versus typical KOA. These data suggest there may be different mechanisms driving the early structural disease progression between accelerated versus typical KOA. Clin.

Erythromycin treatment for gastrointestinal dysmotility in preterm infants

To report our clinical experience on the use of oral erythromycin for the treatment of severe gastrointestinal dysmotility in preterm infants.

Methodology:

A case series study of seven preterm infants (six were very low birthweight) with severe intestinal dysmotility in a tertiary neonatal centre.

Results:

All responded favourably without adverse effects and tolerated full enteral feeding within 1–2 weeks of the commencement of the drug.

Conclusions:

As prolonged total parenteral nutrition carries significant risk of complications, this therapy could be considered in selected preterm infants who fail to establish enteral feeding after an extended period, and in whom an anatomically obstructive lesion of the gastrointestinal tract has been excluded. Meanwhile, we would caution against the widespread implementation of this therapeutic approach until formal evaluation by randomized controlled trials have established the exact role of erythromycin, or its analogues, in the treatment of intestinal dysmotility in preterm infants.

Complementary medicine: use and attitudes among GPs

BACKGROUND: Information about use and attitudes of GPs towards complementary medicine is required in order to inform the debate about its place within mainstream medicine. There is evidence that public use of complementary medicine is particularly high in the South-West of England. OBJECTIVE: This study aimed to determine the use of, and attitudes towards, complementary medicine among GPs. METHODS: A questionnaire survey was performed of all primary care physicians working in the health service in Devon and Cornwall. RESULTS: Replies were received from 461 GPs, a response rate of 47%. A total of 314 GPs (68%, range 32-85%) had been involved in complementary medicine in some way during the previous week. One or other form of complementary medicine was practised by 74 of the respondents (16%), the two most common being homoeopathy (5.9%) and acupuncture (4.3%). In addition, 115 of the respondents (25%) had referred at least one patient to a complementary therapist in the previous week, and 253 (55%) had endorsed or recommended treatment with complementary medicine. Chiropractic, acupuncture and osteopathy were rated as the three most effective therapies, and the majority of respondents believed that these three therapies should be funded by the health service. A total of 176 (38%) of respondents reported adverse effects, most commonly after manipulation. CONCLUSION: Over two-thirds of the GPs in Devon and Cornwall who responded to the survey had been involved with complementary medicine in some way during the previous week. This figure is higher than the national average. The majority of respondents believed that acupuncture, chiropractic and osteopathy were effective and should be funded by the NHS.      

Effect of shunt surgery on spleen size, portal pressure and oesophageal varices in patients with non-cirrhotic portal hypertension

Shunt surgery is considered to be the treatment of choice in patients with non-cirrhotic portal hypertension. There is little data on the effect of side-to-side lieno-renal (SSLR) shunt on oesophageal variceal size, splenic size and splenic pulp pressure (SPP) in patients with non-cirrhotic portal hypertension. We evaluated pre- and postoperatively endoscopic grading of varices, splenic size and SPP for predicting shunt patency in 86 patients with non-cirrhotic portal hypertension: 56 with extrahepatic portal venous obstruction (EHPVO) and 30 with non-cirrhotic portal fibrosis (NCPF). The EHPVO patients with patent shunts (n= 47) showed significant reduction in SPP (pre-operative 43.56±7.9 vs postoperative 29.96±7.7 cm of saline), splenic size (6.5±2.8 vs 4.00±2.6 cm below costal margin) and varices grades (2.96±0.5 vs 0.92±0.8). Patients with blocked shunt (n= 9) did not show significant reduction in SPP and varices grades. However, there was reduction in spleen size (8.6±3.0 vs 6.3±4.3). In the NCPF group, 28 had patent shunts and showed significant reduction in SPP (46.3±13.5 vs 33.8±7.6 cm of saline), splenic size (9.1±3.3 vs 6.8±4.6 cm below costal margin) and varices grades (2.8±0.7 vs 1.05±0.96). As only two patients with NCPF had blocked shunts, no statistical comparison between patients with patent and patients with blocked shunts could be done. In conclusion, following SSLR, there is a significant reduction in SPP and varices grades in patients with patent shunts. Endoscopic grading of varices can be used to predict shunt patency. However, spleen size is not a good criteria for predicting shunt patency.
