Adherence to UK national guidance for discharge information: an audit in primary care

Aims: Poor communication of clinical information between healthcare settings is associated with patient harm. In 2008, the UK National Prescribing Centre (NPC) issued guidance regarding the minimum information to be communicated upon hospital discharge. This study evaluates the extent of adherence to this guidance and identifies predictors of adherence. Methods: This was an audit of discharge summaries received by medical practices in one UK primary care trust of patients hospitalized for 24 h or longer. Each discharge summary was scored against the applicable NPC criteria which were organized into: ‘patient, admission and discharge’, ‘medicine’ and ‘therapy change’ information. Results: Of 3444 discharge summaries audited, 2421 (70.3%) were from two teaching hospitals and 906 (26.3%) from three district hospitals. Unplanned admissions accounted for 2168 (63.0%) of the audit sample and 74.6% (2570) of discharge summaries were electronic. Mean (95% CI) adherence to the total NPC minimum dataset was 71.7% [70.2, 73.2]. Adherence to patient, admission and discharge information was 77.3% (95% CI 77.0, 77.7), 67.2% (95% CI 66.3, 68.2) for medicine information and 48.9% (95% CI 47.5, 50.3) for therapy change information. Allergy status, co-morbidities, medication history and rationale for therapy change were the most frequent omissions. Predictors of adherence included quality of the discharge template, electronic discharge summaries and smaller numbers of prescribed medicines. Conclusions: Despite clear guidance regarding the content of discharge information, omissions are frequent. Adherence to the NPC minimum dataset might be improved by using comprehensive electronic discharge templates and implementation of effective medicines reconciliation at both sides of the health interface

Predictors of outcomes in diabetic foot osteomyelitis treated initially with conservative (nonsurgical) medical management: A retrospective study

The optimal way to manage diabetic foot osteomyelitis remains uncertain, with debate in the literature as to whether it should be managed conservatively (ie, nonsurgically) or surgically. We aimed to identify clinical variables that influence outcomes of nonsurgical management in diabetic foot osteomyelitis. We conducted a retrospective study of consecutive patients with diabetes presenting to a tertiary center between 2007 and 2011 with foot osteomyelitis initially treated with nonsurgical management. Remission was defined as wound healing with no clinical or radiological signs of osteomyelitis at the initial or contiguous sites 12 months after clinical and/or radiological resolution. Nine demographic and clinical variables including osteomyelitis site and presence of foot pulses were analyzed. We identified 100 cases, of which 85 fulfilled the criteria for analysis. After a 12-month follow-up period, 54 (63.5%) had achieved remission with nonsurgical management alone with a median (interquartile range) duration of antibiotic treatment of 10.8 (10.1) weeks. Of these, 14 (26%) were admitted for intravenous antibiotics. The absence of pedal pulses in the affected foot (n = 34) was associated with a significantly longer duration of antibiotic therapy to achieve remission, 8.7 (7.1) versus 15.9 (13.3) weeks (P = .003). Osteomyelitis affecting the metatarsal was more likely to be amputated than other sites of the foot (P = .016). In line with previous data, we have shown that almost two thirds of patients presenting with osteomyelitis healed without undergoing surgical bone resection

The association between glycaemic control, renal function and post-operative ophthalmic complications in people with diabetes undergoing cataract surgery: A single-centre retrospective analysis

Introduction: In general surgery, it has been shown that poor peri-operative diabetes control, as measured by glycated haemoglobin (HbA1c), is associated with adverse post-operative outcomes. National data for the UK suggest that the post-operative complication rate for cataract surgery is 2.8%. It is unknown whether people with diabetes who undergo cataract surgery are also at increased risk. Methods: This single-centre retrospective study looked at the association of peri-operative HbA1c and estimated glomerular filtration rate (eGFR) with the risk of post-operative complications in people undergoing phacoemulsification and intraocular lens implantation under local anaesthesia during 2016. Results: 4401 individuals had cataract surgery. Of these, 34.6% (1525) had diabetes. Of those with diabetes, 114 (7.5%) developed a post-operative ophthalmological complication (as defined by the Royal College of Ophthalmologists) necessitating at least one eye clinic appointment. Mean HbA1c did not differ between those who did and those who did not develop complications (52 vs 50 mmol/mol, p = 0.12). After adjustment, HbA1c was not a significant risk (OR 1.00; 95% CI: 0.99–1.05; p = 0.85). However, eGFR had a small but statistically significant effect on outcome (OR 0.99; 95% CI: 0.98–1.00; p = 0.02). Conclusions: This study has shown that more people who undergo cataract surgery have diabetes than previously reported. Also, people with diabetes are at higher risk of developing complications than previously reported. HbA1c concentration was not a factor in these adverse post-operative outcomes. However, eGFR was a predictor of risk. More focus should be placed on pre-operatively optimising co-morbidities than diabetes control in those undergoing cataract surgery

A feasibility study of indocyanine green fluorescence mapping for sentinel lymph node detection in cutaneous melanoma

Objectives: Sentinel lymph node biopsy (SLNB) is standard of care for staging regional LN in AJCC stage IB-IIC melanoma; using dual localization with radiolabelled colloid and blue dye. Combining these gives optimal accuracy; drawbacks include cumulative radiation exposure for healthcare workers, coordination between disciplines and anaphylaxis. An alternative tracer agent is indocyanine green (ICG); an optical enhancer that fluoresces in the near infrared range. This prospective cohort study assesses the feasibility of using ICG as a tracer agent to detect SLN in cutaneous melanoma. Methods: Primary melanoma patients diagnosed with pT1b-pT4b tumours undergoing SLNB were recruited over a 6-month period at a tertiary referral centre. All underwent standard preoperative lymphoscintigraphy (LSG) using 20-40MBq of Tc99radiolabelled nanocolloid plus intraoperative Patent Blue dye (PBD). ICG was administered as a third tracer agent intraoperatively. Results: 62 patients (33M/29F) were recruited; median age was 61 years. Median melanoma Breslow thickness was 1.6mm. 144 specimens containing 135 SLN were excised. Concordance rate for all 3 tracer agents was 88.1%(119/135 LN); that for radioisotope/PBD was 88.2%(95%CI:82.2,93.7). There were no discordance pairs between radioisotope/PBD compared to radioisotope/PBD/ICG. Radioisotope/ICG significantly increased the sensitivity of detecting SLN to 98.5%(95%CI:94.8,99.8); p<0.00001 compared to radioisotope/PBD. Concordance rate of intraoperative ICG drainage pattern with LSG was 22.6%. Conclusion: ICG utilization showed comparable sensitivity with gold standard. Technical challenges e.g. ICG leakage into biopsy field, poor concordance with LSG limits its efficacy in melanoma SLNB. We therefore do not recommend replacing current practice with ICG alone or by using a combination with TC99

Electrode pad suitability for repeated application to the head and neck

Electrode pads are an integral component of ambulatory monitoring, providing an interface to conduct and record bioelectrical signals. During a previous clinical investigation involving our device for monitoring patients with dizziness, 53% of individuals experienced temporary redness and inflammation after wearing standard ECG electrode pads on the face for up to 30 days. We postulated that this was caused by a combination of the material composition of the electrode pads and through skin stripping due to their daily replacement. To test this hypothesis, we undertook a further study to determine which combination of electrode pad and replacement regime was most tolerable to the skin. Participants wore three different electrode pads on both sides of their face for 30 days. Electrode pads on the left were replaced daily, and those on the right on alternate days. Participants were instructed to inspect their skin after removal and to not reapply a new electrode pad if they noticed any unexpected changes to the condition of their skin. Electrode pad performance was measured by the duration of wear. The two best performing electrode pads contained a wet gel rather than a solid, adhesive gel, but the advantage of replacing electrode pads on alternate days was negligible. The chloride concentration of the gels was found to be likely factor in determining tolerability. The results suggest that optimal tolerability for ambulatory monitoring on the head and neck is provided by electrode pads containing a wet gel and a low chloride concentration

Pharmacist provided medicines reconciliation within 24 hours of admission and on discharge: A randomised controlled pilot study

Background: The UK government currently recommends that all patients receive medicines reconciliation (MR) from a member of the pharmacy team within 24 hours of admission and subsequent discharge. The cost-effectiveness of this intervention is unknown. A pilot study to inform the design of a future randomised controlled trial to determine effectiveness and cost-effectiveness of a pharmacist delivered service was undertaken. Method: Patients were recruited seven days a week from five adult medical wards in one hospital over a 9 month period and randomised using an automated system to intervention (MR within 24 hours of admission and at discharge) or usual care which may include MR (control). Recruitment and retention rates were determined. Length of stay(LOS), quality of life (EQ-5D-3L), unintentional discrepancies(UDs) and emergency re-admission(ER) within 3 months were tested as outcome measures. The feasibility of identifying and measuring intervention associated resources was determined. Result: 200 patients were randomised to either intervention or control. Groups were comparable at baseline.95(99%) of patients in the intervention received MR within 24 hours, whilst 62(60.8%) of control patients received MRat some point during admission. The intervention resolved 250 of the 255 UDs identifed at admission. Only 2 UDs were identifed in the intervention group at discharge compared with 268 in the control. The median LOS was 94 hours in the intervention arm and 118 hours in the control, with ER rates of 17.9% and 26.7%,respectively. Assuming 5% loss to follow up 1120 patients (560 in each arm) are required to detect a 6% reduction in 3 month ER rates. Conclusions: The results suggest that changes in outcome measures resulting from MR within 24 hours were in the appropriate direction and readmission within 3 months is the most appropriate primary outcome measure. A future study to determine cost-effectiveness of the intervention is feasible and warranted

The impact of glycaemic variability on wound healing in the diabetic foot – a retrospective study of new ulcers presenting to a specialist multidisciplinary foot clinic

Aims: Glycaemic variability – the visit-to-visit variation in HbA1c – plays a possible role in the development of micro and macrovascular disease in patients with diabetes. Whether HbA1c variability is a factor determining wound healing in diabetic foot ulcers remains unknown. We aimed to determine whether HbA1c variability is associated with foot ulcer healing time. Methods: A retrospective analysis of patients presenting to our specialist multidisciplinary foot clinic between July 2013 and March 2015, with at least three HbA1c measurements within five years of presentation and more than two follow-up reviews. HbA1c variation was measured by magnitude of standard deviation. Results: 629 new referrals were seen between July 2013 and March 2015. Of these, 172 patients had their number of days to healing recorded and sufficient numbers of HbA1c values to determine variability. The overall geometric mean days to heal was 91.1 days (SD 80.8 to 102.7). In the low HbA1c variability group the geometric mean days to heal was 78.0 days (60.2 to 101.2) vs 126.9 days (102.0 to 158.0) in the high Hb1Ac variability group (p=0.032). Those with low HbA1c (< 58 mmol/mol) and low variability healed faster than those with high HbA1c and high variability (73.5 days [59.5 to 90.8] vs 111.0 days [92.0 to 134.0], p=0.007). Additionally, our results show that time to healing is more dependent on the mean HbA1c than the variability in HbA1c (p=0.007). Conclusions/interpretation: Our data suggest that there was a significant association between HbA1c variability and healing time in diabetic foot ulcers

Presentation of dizziness in individuals with chronic otitis media: data from the multinational collaborative COMQ-12 study

Purpose: In chronic otitis media (COM), disease chronicity and severity of middle ear inflammation may influence the development of inner ear deficits, increasing the risk of vestibular impairment. This secondary analysis of the multinational collaborative Chronic Otitis Media Questionnaire-12 (COMQ-12) dataset sought to determine the prevalence of vestibular symptoms in patients with COM and identify associated disease-related characteristics. Methods: Adult patients with a diagnosis of COM in outpatient settings at nine otology referral centers across eight countries were included. We investigated the presence of vestibular symptoms (dizziness and/or disequilibrium) using participant responses to item 6 of a native version of the COMQ-12. Audiometric data and otoscopic assessment were also recorded. Results: This analysis included 477 participants suffering from COM, with 56.2% (n = 268) reporting at least mild inconvenience related to dizziness or disequilibrium. There was a significant association between air conduction thresholds in the worse hearing ear and presence of dizziness [adjusted odds ratio (AOR), 1.01; 95% CI 1.00–1.02; p = 0.0177]. Study participants in European countries (AOR 1.53; 95% CI 1.03–2.28; p = 0.0344) and Colombia (AOR 2.48; 95% CI 1.25–4.92; p = 0.0096) were more likely to report dizziness than participants in Asian countries. However, ear discharge and cholesteatoma showed no association with dizziness in the adjusted analyses. Conclusion: Vestibular symptoms contribute to burden of disease in patients with COM and associates with hearing disability in the worse hearing ear. Geographical variation in presentation of dizziness may reflect financial barriers to treatment or cultural differences in how patients reflect on their health state

Assessing the quality of primary care referrals to surgery of patients with diabetes in the East of England: A multi-centre cross-sectional cohort study

Aim: Peri-operative hyperglycaemia is associated with an increased incidence of adverse outcomes. Communication between primary and secondary care is paramount to minimise these harms. National guidance in the UK recommends that the glycated haemoglobin (HbA1c) should be measured within 3 months prior to surgery and that the concentration should be less that 69 mmol/mol (8.5%). In addition, national guidance outlines the minimum dataset that should be included in any letter at the time of referral to the surgeons. Currently, it is unclear how well this process is being carried out. This study investigated the quality of information being handed over during the referral from primary care to surgical outpatients within the East of England. Methods: Primary care referrals to nine different NHS hospital Trusts were gathered over a 1-week period. All age groups were included from 11 different surgical specialties. Referral letters were analysed using a standardised data collection tool based on the national guidelines. Results: A total of 1919 referrals were received, of whom 169 (8.8%) had previously diagnosed diabetes mellitus (DM). However, of these, 38 made no mention of DM in the referral letter but were on glucose-lowering agents. Only 13 (7.7%) referrals for patients with DM contained a recent HbA1c, and 20 (11.8%) contained no documentation of glucose-lowering medication. Conclusion: This study has shown that the quality of referral letters to surgical specialties for patients with DM in the East of England remain inadequate. There is a clear need for improving the quality of clinical data contained within referral letters from primary care. In addition, we have shown that the rate of referral for surgery for people with diabetes is almost 50% higher than the background population with diabetes
