Electronic Medication Record Accuracy in Haemodialysis Outpatient Settings.

Aims Irish haemodialysis (HD) units operate the electronic Kidney Disease Clinical Patient Management System (KDCPMS). KDCMPS is not always used as the primary electronic patient record. At this study setting, KDCPMS information accuracy has not been examined to date. This study aims to identify, characterise and quantify medication discrepancies within KDCPMS records of HD outpatients. Methods Prospective, observational study conducted on the HD unit of Tallaght University Hospital. Medicine reconciliation was conducted to identify KDCPMS discrepancies with medication review to document Drug Related Problems (DRPs). Clinical pharmacists issued recommendations to resolve DRPs. Results All KDCPMS records examined contained intentional and unintentional discrepancies (n=36). Unintentional discrepancies corresponding to 8.8 discrepancies per patient (5.13SD) was observed. One-hundred-and-forty-three DRPs were identified in 34 patients (94.4%). Sixty-five per cent (65%) of pharmacist recommendations were accepted (n=93), 22.4% rejected (n=32), 8.4% (n=12) referred to the renal multidisciplinary team (MDT) and 4.2% not actioned (n=6). Conclusion KDCPMS contains inaccuracies potentially leading to systemic error. Robust clinical governance supported by national policy is required to support KDCPMS as the primary platform for renal patients. Enhanced pharmaceutical care by specialist clinical pharmacists should be supported within national models of care for chronic disease management to improve patient outcomes.

The Perception of Art among Patients and Staff on a Renal Dialysis Unit.

This study investigated the purpose and effectiveness of giving outpatients an opportunity to engage in art activities while receiving dialysis treatment. A mixed method study was conducted. 21 semi-structured interviews were conducted with outpatients attending the dialysis unit and 13 surveys of clinicians were completed. The principle reasons to partake in the art activity programme included: to pass time, to relieve boredom, to be creative, to try something new, distraction from concerns, to stay positive and to achieve something new. Patients who did not participate in the programme pass their time primarily by watching TV or sleeping. All staff who partook in the survey were satisfied with the programme and wanted it to continue. Our findings indicate that the creative arts programme is viewed positively by staff and patients alike, and might be useful in other hospital departments. Further in depth qualitative research would be useful to interrogate the potential effect of engagement in art on positive mental health and quality of life for patients with chronic conditions.

An Approach to Optimise Therapeutic Vancomycin Dosage in a Haemodialysis Population.

Haemodialysis patients are at risk of gram-positive bacteraemia and commonly require intravenous vancomycin. Intravenously administered vancomycin is primarily excreted by the kidney and exhibits complex pharmacokinetics in haemodialysis patients; achieving therapeutic levels can be challenging. An audit in our unit showed current practises of vancomycin administration resulted in a high proportion of sub-therapeutic levels. A new protocol was developed with fixed weight-based loading and subsequent dosing guided by pre-dialysis levels, target levels were 10-20mg/L. Its effectiveness was prospectively evaluated between 24th September 2012, and 8th February 2013. During this period 25 patients commenced vancomycin, 15 were included. In total, 112 vancomycin levels were taken, 94 (84%) were therapeutic, this was a significant improvement compared to previous practise (odds ratio 5.4, CI 3.1-9.4, p<0.0001). In conclusion, our study shows this protocol can consistently and reliably achieve therapeutic vancomycin levels.

Prediction of hospital mortality by changes in the estimated glomerular filtration rate (eGFR).

Deterioration of physiological or laboratory variables may provide important prognostic information. We have studied whether a change in estimated glomerular filtration rate (eGFR) value calculated using the (Modification of Diet in Renal Disease (MDRD) formula) over the hospital admission, would have predictive value. An analysis was performed on all emergency medical hospital episodes (N = 61964) admitted between 1 January 2002 and 31 December 2011. A stepwise logistic regression model examined the relationship between mortality and change in renal function from admission to discharge. The fully adjusted Odds Ratios (OR) for 5 classes of GFR deterioration showed a stepwise increased risk of 30-day death with OR's of 1.42 (95% CI: 1.20, 1.68), 1.59 (1.27, 1.99), 2.71 (2.24, 3.27), 5.56 (4.54, 6.81) and 11.9 (9.0, 15.6) respectively. The change in eGFR during a clinical episode, following an emergency medical admission, powerfully predicts the outcome.

Cinacalcet reduces plasma intact parathyroid hormone, serum phosphate and calcium levels in patients with secondary hyperparathyroidism irrespective of its severity.

AIMS: To evaluate the relationship between the severity of secondary hyperparathyroidism (SHPT) - defined in terms of baseline plasma intact parathyroid hormone (iPTH) level - and the magnitude of response to cinacalcet. MATERIALS AND METHODS: In this post hoc analysis, data were pooled from three randomized, placebo-controlled trials in which dialysis patients with iPTH ≥ 300 pg/ml were dose-titrated with cinacalcet or placebo in addition to conventional treatment to achieve iPTH ≤ 250 pg/ml. In 953 patients analyzed (cinacalcet, 545; placebo, 408), baseline iPTH levels were categorized in 100 pg/ml intervals (300 - ≥ 1,000 pg/ml), and the impact of baseline iPTH on changes in iPTH, phosphate (P), calcium (Ca) and calcium- phosphate product (Ca × P) was evaluated. RESULTS: Cinacalcet reduced iPTH (47% reduction), P (9%), Ca (7%), and Ca × P (15%) across all subgroups. For patients receiving cinacalcet, the mean percentage reduction from baseline in iPTH varied from 35 to 55%, being consistently decreased across the severity subgroups. The mean absolute change in iPTH was more pronounced in patients with higher baseline iPTH levels, particularly in the ≥ 1,000 pg/ml subgroup vs. the other subgroups. However, as baseline iPTH levels increased, iPTH ≤ 250 pg/ml was achieved in fewer patients. A trend towards greater absolute change from baseline was observed for P in patients with more severe disease (iPTH ≥ 800 pg/ml) treated with cinacalcet compared with patients with less severe disease (iPTH 300 - < 800 pg/ml). CONCLUSIONS: Cinacalcet lowers plasma iPTH and serum P, Ca and Ca × P levels in dialysis patients with SHPT, regardless of disease severity. Patients with more severe disease experienced greater reductions in PTH and P, but fewer achieved iPTH ≤ 250 pg/ml by the efficacy assessment phase. Use of cinacalcet when baseline PTH is lower may result in more stable control of SHPT and help to control bone and mineral alterations.

An unusual case of cancer of the urachal remnant following repair of bladder exstrophy.

INTRODUCTION: We report the first case of cancer of the urachal remnant following repair of bladder exstrophy, in a renal transplant recipient. METHOD: A retrospective review of this clinical case and the associated literature were performed. CONCLUSION: This unusual case highlights two very rare entities. Bladder exstrophy has an incidence of 1 in 50,000 newborns, whereas urachal cancer accounts for less than 1% of all bladder tumours.

Chronic kidney disease in the elderly; a silent epidemic.

Chronic kidney disease has been shown to be associated with significant increases in mortality and morbidity even in early stages. Despite this it is rarely diagnosed, actively investigated or managed in the elderly. We set out to establish the prevalence of CKD and identify causative factors in a consecutive series of referrals to a geriatric medical clinic. We calculated glomerular filtration rates (GFR) for 101 patients attending a geriatric medical clinic using the Cockroft and Gault formula, and collected data on medications and relevant past medical history. Mild CKD (GFR <60ml/min) was present in 80% of the group. Only 10% of these patients had serum creatinine >130(mmol/L. hypertension was present in 50% and only 9% were diabetic. Almost one third were on inappropriate drugs or dosages; most commonly non-steroidal anti-inflammatory drugs (99%). Chronic kidney disease is extremely common in older people attending a geriatric medical clinic and carries significant risks. CKD will not be detected by serum creatinine alone in 90% of cases. Routine calculation of GFR should be used to provide a more accurate measure of renal impairment and allow earlier intervention, risk factor reduction and improve prescribing practices.

Adequacy targets can be met in anuric patients by automated peritoneal dialysis: baseline data from EAPOS.

OBJECTIVE: Conventional continuous ambulatory peritoneal dialysis (CAPD) in patients without residual renal function and with high solute transport is associated with worse clinical outcomes. Automated peritoneal dialysis (APD) has the potential to improve both solute clearance and ultrafiltration in these circumstances, but its efficacy as a treatment modality is unknown. The European Automated Peritoneal Dialysis Outcomes Study (EAPOS) is a 2-year, prospective, European multicenter study designed to determine APD feasibility and clinical outcomes in anuric patients. The present article describes the baseline data for patients recruited into the study. DESIGN: All PD patients treated in the participating centers were screened for inclusion criteria [urinary output < 100 mL/24 h, or residual renal function (RRF) < 1 mL/min, or both]. After enrollment, changes were made to the dialysis prescription to achieve a weekly creatinine clearance above 60 L per 1.73 m2 and an ultrafiltration rate above 750 mL in 24 hours. SETTING: The study is being conducted in 26 dialysis centers in 13 European countries. BASELINE DATA COLLECTION: The information collected includes patient demographics, dialysis prescription, achieved weekly creatinine clearance, and 24-hour ultrafiltration (UF). RESULTS: The study enrolled 177 anuric patients. Median dialysis duration before enrollment was 22.5 months (range: 0-285 months). Mean solute transport measured as the dialysate-to-plasma ratio of creatinine (D/P(Cr)) was 0.74 +/- 0.12. Patients received APD for a median of 9.0 hours overnight (range: 7-12 hours) using a median of 11.0 L of fluid (range: 6-28.75 L). Median daytime volume was 4.0 L (range: 0.0-9.0 L). Tidal dialysis was used in 26 patients, and icodextrin in 86 patients. At baseline, before treatment optimization, the weekly mean total creatinine clearance was 65.2 +/- 14.4 L/1.73 m2, with 105 patients (60%) achieving the target of more than 60 L/1.73 m2. At baseline, 81% of patients with high transport, 69% with high-average transport, and 40% with low-average transport met the target. At baseline, 70% of patients with a body surface area (BSA) below 1.7 m2, 60% with a BSA of 1.7-2.0 m2, and 56% with a BSA above 2.0 m2 achieved 60 L/1.73 m2 weekly. Median UF was 1090 mL/24 h, and 75% of patients achieved the UF target of more than 750 mL/24 h. CONCLUSION: This baseline analysis of anuric patients recruited into the EAPOS study demonstrates that a high proportion of anuric patients on APD can achieve dialysis and ultrafiltration targets using a variety of regimes. This 2-year follow-up study aims to optimize APD prescription to reach predefined clearance and ultrafiltration targets, and to observe the resulting clinical outcomes.

Leptospirosis in the South-Eastern Health Board region of the Republic of Ireland: 1990 to 1996.

The South-Eastern Health Board (SEHB) has the highest annual incidence of leptospirosis in the Republic of Ireland (12.3/million according to hospital inpatient enquiry data; 10.4/million by serology). Discharge diagnosis correlates strongly with numbers of cattle, but not of other livestock, which may indicate a true association with leptospirosis or may reflect an increased clinical suspicion in areas where livestock are prevalent.

Leptospirosis in the Republic of Ireland: 1985 to 1996.

Official government statistics and serological laboratory data provide limited information about the incidence of leptospirosis in the Republic of Ireland. The mean annual notified incidence in the Republic of Ireland from 1985 to 1996 was 1.3/million. The incidence according to hospital discharge diagnosis was higher at 4.9/million. One hundred and seventy-five serologically confirmed cases of leptospirosis were reported from 1986 to 1996, giving a mean annual incidence of 4.5/million. The true incidence of leptospirosis in the Republic of Ireland is probably higher, as hospital discharge data are incomplete and full serological testing was not always performed. Our data indicate that leptospirosis is an underestimated public health problem with only 26% of cases being notified. A national communicable disease surveillance centre in the Republic of Ireland would facilitate better monitoring and understanding of this disease.
