Implementation of behaviour change training in practice amongst pharmacy professionals in primary care settings: Analysis using the COM-B model.

BACKGROUND: The Pharmacy Integration Fund (PhIF) was established in England in 2016, with funded learning programmes or 'pathways' designed to support the development of clinical pharmacy practice in a range of settings. Despite pharmacy staff being well positioned to provide more clinical work, limited research has investigated behaviour change training targeted at widespread practice transformation. OBJECTIVE(S): To investigate implementation of PhIF learning in practice, using the COM-B model of behaviour change. METHODS: An online survey distributed in February and October 2020 included questions on motivations for learning, confidence in target behaviours and impact of PhIF training on behaviour. The October 2020 survey also included questions exploring the effect of the COVID-19 pandemic. Quantitative data were analysed in SPSS. v.27 (IBM). Inferential statistics were used to compare between the pathways (Primary care pathways [PCP], Post-registration pathway [PRP] and Accuracy Checking Pharmacy Technician [ACPT] pathway). Free text comments were categorised and themed. RESULTS: Three-hundred and eighty-three responses were received (49% PRP learners, 39% PCP learners and 12% ACPT learners). Learners generally had the capacity and opportunities to apply learning, and were strongly motivated to implement behaviours in practice, although learners based in community pharmacy (those on the PRP) were less likely to report receiving employer support. Enhanced knowledge/skills (capacity) were more commonly reported than change to patient-facing activities, leading clinical services and conducting medication reviews with patients with complex needs (clinical practice behaviours targeted by the pathways). The COVID-19 pandemic heightened barriers to implementing practice change. CONCLUSIONS: Implementation of a range of clinical practice behaviours following at scale training appears to have been largely successful. Despite this, the community pharmacy context, where funded service opportunities may be lacking, continues to present challenges to workforce transformation plans. More work is needed to understand how training can be implemented to promote practice change for pharmacy professionals in all settings.

Direct access: lessons learnt from the Netherlands.

OBJECTIVE: To use a qualitative approach to examine the perceptions of policy makers, general dental practitioners, dental hygienists, dental students and dental hygiene students in the Netherlands following the introduction of a direct access policy in 2006. METHODS: Semi-structured interviews and focus groups were undertaken with a variety of policy makers and clinicians in the Netherlands. These were recorded and transcribed verbatim into MS Word documents. The transcripts were line numbered and subjected to thematic analysis to develop a coding frame using NVivo. RESULTS: Four main themes are reported, which represent a subset of a policy analysis of direct access in the Netherlands. These were entitled: 'The narrative of implementation', 'Working models of direct access', 'Relationship between old- and new-style hygienists' and 'Public attitudes'. CONCLUSIONS: Working relationships within integrated practices in the Netherlands are positive, but attitudes towards independent practice are mixed. Good examples of collaborative working across practices were observed, but relationships between the professional bodies remain difficult seven years on since the introduction of the policy.

Biomechanics of the meniscus-meniscal ligament construct of the knee.

The menisci of the knee act primarily to redistribute contact force across the tibio-femoral articulation. This meniscal function is achieved through a combination of the material, geometry and attachments of the menisci. The main ligaments that attach the menisci to the tibia (insertional ligaments, deep medial collateral ligament), the femur (meniscofemoral ligaments, deep medial collateral ligament) and each other (the anterior intermeniscal ligament) are the means by which the contact force between tibia and femur is distributed into hoop stresses in the menisci to reduce contact pressure at the joint. This means that the functional biomechanics of the menisci cannot be considered in isolation and should be considered as the functional biomechanics of the meniscus-meniscal ligament construct. This article presents the current knowledge on the anatomy and functional biomechanics of the meniscus and its associated ligaments. Much is known about the function of the meniscus-meniscal ligament construct; however, there still remain significant gaps in the literature in terms of the properties of the anterior intermeniscal ligament and its function, the properties of the insertional ligaments, and the most appropriate ways to reconstruct meniscal function surgically.

The consequences of meniscectomy.

The menisci of the knee have an important role in load-bearing and shock absorption within the joint. They may also function as secondary stabilisers, have a proprioceptive role, and aid the lubrication and nutrition of the articular cartilage. Complete or partial loss of a meniscus can have damaging effects on a knee, leading to serious long-term sequelae. This paper reviews the consequences of meniscectomy and summarises the body of evidence in the literature regarding those factors most relevant to long-term outcome.

Management of suspected scaphoid fractures in accident and emergency departments--time for new guidelines.

INTRODUCTION: The objectives of this work were to assess the clinical knowledge of clinicians in the accident and emergency (A&E) departments in England & Wales and evaluate the current trend for the acute management of radiologically normal, but clinically suspected, fractures of the scaphoid. SUBJECTS AND METHODS: We conducted a telephone survey on 146 A&E senior house officers (SHOs) in 50 different hospitals. This survey assessed the clinicians' experience, their clinical and radiological diagnostic methods, and their initial treatment of suspected scaphoid fractures. RESULTS: The majority (55.8%) of SHOs performed only one clinical test to diagnose suspected scaphoid fractures. Overall, 41% were unable to cite the number of the radiographic views taken and only 10% of departments have direct access to further radiological investigation. There is wide variation in the early treatment of this injury, with the scaphoid cast used most commonly (46%). The majority of SHOs (89%) were unable to describe the features of immobilisation. The mean follow-up period was 10 days, and 53% of cases were followed-up by the senior staff in A&E. Of SHOs, 54% were not aware of any local guidelines for the management of suspected scaphoid fractures in their departments, and 92% were not aware of the existence of the 1992 British Association for Accident and Emergency Medicine (BAEM) guidelines. CONCLUSIONS: The clinical knowledge and the management of suspected scaphoid fractures in A&E are unsatisfactory. We, therefore, suggest that the dissemination of up-to-date guidelines could help to educate clinicians to provide better care to the patients.

An anatomical study of meniscal allograft sizing.

Meniscus-to-femoral condyle congruity is essential for the development of circumferential hoop stresses and thus function of the meniscus. When meniscal allograft transplantation is performed using bony anchorage of the insertional ligaments, accurate graft-to-host size matching is therefore essential. The standard method currently employed for size matching of meniscal allografts is to rely on plain radiographs of the host's knee, from which expected meniscal dimensions are measured. This study aimed to examine the correlation between tibial plateau dimensions and meniscal dimensions. We studied 44 donor tibial plateaus with medial and lateral meniscal allografts attached intact. Meniscal and tibial plateau dimensions were measured. Linear regression analysis was used to calculate expected meniscal dimensions from each specimen's plateau dimensions. Using specific medial and lateral tibial plateau width and length measurements, meniscal dimensions could be predicted with a mean error of only 5.0+/-6.4%. When predicting meniscal dimensions from only total bony plateau width, the mean error observed was 6.2+/-8.0%. The difference between the two methods was not statistically significant. The results suggest that meniscal dimensions can be predicted accurately from tibial plateau measurements, with only small mean errors. However, potential size mismatches should be carefully borne in mind by surgeons using meniscal allografts.

A biomechanical study of four different meniscal repair systems, comparing pull-out strengths and gapping under cyclic loading.

Most studies comparing the biomechanical properties of different meniscal repair systems have simply investigated load to failure. Meniscal tissue is highly anisotropic, and far weaker under tension in the radial direction. Radially oriented loading to failure may not therefore be the most physiologically relevant in vitro test for repair of circumferential tears, and determining gapping across repair sites under cyclical loading at lower loads may be of greater importance. Using bovine menisci, vertical circumferential incisions were repaired using a simple vertical 2-0 PDS suture, Meniscal Arrow, Meniscal Fastener or T-Fix. Repairs were tested by simple loading to failure in a materials testing machine, and by cyclic loading between 5 and 10 N for 25 cycles. Initial gapping across the repairs was measured using a digital micrometer, and the increase in gapping under cyclic loading measured using a Differential Voltage Reluctance Transducer. The mean loads to failure for each of the repair groups were: sutures 72.7 N, Arrows 34.2 N, Fasteners 40.8 N and T-Fix 49.1 N. The load to failure was significantly greater with sutures than with Arrows or Fasteners. The mean gapping across the repairs for each of the repair groups after 25 loading cycles were: sutures 3.29 mm, Arrows 2.18 mm, Fasteners 3.99 mm and T-Fix 3.47 mm. The mean gapping was significantly less with Arrows than with Sutures, Fasteners or T-Fix. These results confirm that meniscal repair by suturing gives the highest load to failure, but show that Arrows give superior hold under lower loads, with the least gapping across repairs under cyclic loading of the four methods tested.

The role of rehydration in the prevention of fat embolism syndrome.

We encountered three cases of young sportsmen developing fat embolism syndrome (FES) after sustaining isolated tibial shaft fractures whilst playing football. All fractures were treated with intra-medullary nails and all three patients were kept nil-by-mouth pre-operatively without intravenous fluids. Correction of shock is often quoted as an important factor in the prevention of FES. However, animal studies have shown that dehydration, as opposed to hypovolaemia, may also be of great importance. We therefore examined the specific gravity of the urine of 20 patients with musculoskeletal injuries sustained during sport. The mean urinary specific gravity was significantly higher than that of a control group of 10 members of staff. We emphasise the importance of adequate pre-operative rehydration, especially if injuries were sustained during heavy exercise, as this may reduce the risk of developing FES.

Meniscofemoral ligaments revisited. Anatomical study, age correlation and clinical implications.

The meniscofemoral ligaments were studied in 84 fresh-frozen knees from 49 cadavers. Combined anterior and posterior approaches were used to identify the ligaments. In total, 78 specimens (93%) contained at least one meniscofemoral ligament. The anterior meniscofemoral ligament (aMFL) was present in 62 specimens (74%), and the posterior meniscofemoral ligament (pMFL) in 58 (69%). The 42 specimens (50%) in which both ligaments were present were from a significantly younger population than that with one MFL or none (p < 0.05). Several anatomical variations were identified, including oblique fibres of the posterior cruciate ligament (PCL), which were seen in 16 specimens (19%). These were termed the 'false pMFL'. The high incidence of MFLs and their anatomical variations should be borne in mind during arthroscopic and radiological examination of the PCL. It is important to recognise the oblique fibres of the PCL on MRI in order to avoid wrongly identifying them as either a pMFL or a tear of the lateral meniscus. The increased incidence of MFLs in younger donors suggests that they degenerate with age.

The internet--friend or foe? A questionnaire study of orthopaedic out-patients.

OBJECTIVE: To examine patients' use of the Internet to obtain medical information, their opinions on the quality of medical Web sites, and their attitudes towards Internet-based consultations. DESIGN: Questionnaire study. PARTICIPANTS AND SETTING: 398 patients, aged 10-95 years, visiting the orthopaedic outpatient clinics of a London district general hospital over a 2-week period. MAIN OUTCOME MEASURES: (i) The rate of Internet use by patients; (ii) the perception of the quality of medical web sites; (iii) future intentions and attitudes towards Internet-based consultations; and (iv) concurrence between information obtained from Web sites and advice given by the orthopaedic surgeon in the clinic. RESULTS: From 369 respondents (response rate 93%), 55.3% of patients had accessed the Internet. Of these, 52.0% had obtained medical information from this source. Access was linearly correlated with age (r2 = 0.975, P < 0.01) and was also related to social status. Of the 12.3% of patients who had researched their particular orthopaedic condition, 20% reported that the advice received from the surgeon in the clinic contradicted that obtained from the Internet. A total of 35.7% of patients would undergo an Internet-based consultation, whilst a further 25.5% would consider this, depending on the medical condition in question. CONCLUSIONS: Over half of the patients studied were willing to access the Internet for medical information, with younger patients more likely to undertake this activity. Moreover, a significant proportion of respondents were willing to undergo an Internet-based consultation. The increased use of medical Web sites by patients raises important issues regarding the need for quality control, and impacts significantly upon the surgeon-patient relationship.

Prospective randomized controlled trial to compare skin staples and polypropylene for securing the mesh in inguinal hernia repair.

BACKGROUND: The Lichtenstein tension-free repair has become the standard method for repairing inguinal hernia in many surgical units. This study compared two methods of mesh fixation. METHODS: Fifty men undergoing unilateral primary Lichtenstein inguinal hernia repair under general anaesthesia were randomized into two groups. In the control group polypropylene mesh was secured with 2/0 polypropylene sutures and the skin closed with subcuticular 3/0 polydioxanone. In the study group polypropylene mesh was secured with skin staples and the skin was closed with staples from the same staple gun. Duration of the operation was recorded. Early follow-up was achieved by patient review at 6 weeks and postal questionnaire at 12 weeks. RESULTS: The operation was significantly shorter when staples were used (median 20 min 0 s versus 29 min 30 s, P < 0.001). There was no significant difference in the incidence of postoperative complications or pain score. The study group reported earlier return to normal activity (4 weeks 0 days versus 6 weeks 2 days, P < 0.01) although there was no difference in the time taken to return to work or driving. CONCLUSION: The use of skin staples to secure mesh in the Lichtenstein inguinal hernia repair significantly reduced the duration of the operation and was as effective as conventional mesh fixation with polypropylene in the short term.

Metastatic papillary thyroid carcinoma presenting as a typical branchial cyst.

Two cases of papillary thryoid carcinoma presenting as a cystic lateral neck mass are reported. This tumour characteristically presents in patients under 40-years-old and in the presence of an occult primary tumour may mimic a branchial cyst. In such cases simple aspiration of the cyst will produce a chocolate-brown serous fluid which excludes the diagnosis of a branchial cyst and is characteristic of papillary thyroid carcinoma. Cytological examination of the fluid has a high degree of sensitivity and specificity in the diagnosis of thyroid malignancy and should avoid delay in diagnosis and unnecessary surgical exploration prior to definitive treatment.

An alginate pick-up alternative to the altered cast technique.

The altered cast technique for distal extension removable partial dentures involves such cumbersome laboratory procedures that many dentists avoid using it. This article presents a simple and easy clinical technique that accomplishes the same objective, but involves no additional laboratory work. In addition, the technique provides superior accuracy when compared with the altered cast technique.

The impact of guidelines on peri-operative antibiotic administration.

A survey has shown that peri-operative antibiotic therapy was inappropriate in 83% of patients undergoing abdominal or arterial surgery. Missed doses at induction or postoperatively, a questionable choice of antibiotics and unnecessarily long postoperative courses were major problems. The introduction of formal guidelines was partially successful with appropriate prescribing improving from 17 to 60% of cases. There was, in addition, a marked reduction in prescribing costs.

A clinical technique for modification of dentures during the implant healing phase.

Merely relieving the tissue surface of an existing denture to be used during implant healing may cause loading of the fixtures during occlusal movements. Creating a window and filling it with soft-tissue conditioner can result in denture breakage. This paper presents a technique for the maintenance of hard denture base in the fixture area, which is completely out of contact with the healing caps, even during forceful seating.
