Impact of chronic kidney disease management in primary care

The introduction of eGFR reporting and publication of national CKD guidelines has led to major challenges in primary and secondary care, leading to an increase in the number of referrals to nephrology clinics. We have shown that introduction of a renal patient care pathway reduces nephrology referrals and enables managed discharges of CKD patients to primary care. The aim of this article is to examine the outcome of patients discharged to primary care to find out if there is an associated risk with increased discharge supported by the patient pathway. The study was carried out within a single NHS Trust covering a population of 560,000. All patients discharged from the trust's renal outpatient clinic between June 2007 and July 2008 were identified. Patient notes and the local laboratory database systems were used to determine the source and timing of tests. A total of 31 new referrals and 57 regular follow-ups were discharged during this period. The median age of discharge was 67.5 years. Most subjects (60%) had CKD stage 3 at the time of discharge. A total of 23% of discharges were categorized as CKD stages 1, 2 or normal and 17% of patients had CKD stage 4. Overall, 93% had stable eGFRs prior to discharge, 77.5% of patients had blood pressure within threshold (140/90 according to UK CKD guidelines) and 97.7% of patients had haemoglobins >10 g/dl. Post-discharge 83% of patients had eGFRs recorded by their general practitioner and 92.6% of these were measured within appropriate time frames as per CKD guidelines. The majority of patients (82%) had either improved or stable eGFR post-discharge and only three patients had a significant decline in their eGFR. These data indicate that selected CKD patients can be appropriately discharged from secondary care and adequately monitored in primary care. Furthermore, we have shown that this was a safe practice for patients.

Early Cholecystectomy after Acute Admission with Cholecystitis: How Much Work?

This study was designed to determine the number of cases and amount of operating room time required, for a population of 600,000, to provide definitive treatment in the form of cholecystectomy for all patients admitted as an emergency with cholecystitis. The total number of patients admitted to a single NHS trust in South East Wales with the diagnosis of cholecystitis during a 1-year period was assessed. The number of laparoscopic cholecystectomies performed and the time taken was investigated with the conversion rates. There were a total of 787 individual emergency admissions attributed to cholecystitis, and 224 patients (36%) underwent cholecystectomy on the same admission. The median operative time was 77 (range, 23-238) min, and the median operating room time was 108 (range, 37-278) min. To treat all patients definitively would necessitate 12 cholecystectomies per week, requiring 1,296 min or 5.4 sessions of operating room time. A population of 600,000 could be expected to generate enough emergency cholecystectomies to require more than one operating session per day. A significant increase in emergency operating room availability would be necessary to allow the provision of definitive treatment for all emergency admissions with cholelithiasis.

Renal quality outcomes framework and eGFR: impact on secondary care

The prognostic significance of impaired renal function has driven the need for its early recognition and the widespread introduction of the estimated glomerular filtration rate (eGFR) reporting, and the incorporation of Chronic Kidney Disease (CKD) in the revised Quality Outcomes Framework (QOF) of the General Medical Services (GMS) contract in the UK. To characterize the effect of these changes on referral numbers and appropriateness to a nephrology service, and the impact of a newly introduced Map of Medicine(R)-based patient care pathway coupled to the systematic screening of all new referrals. The study was carried out within a single NHS Trust covering five primary health care Local Health Boards and a population of 560,000. Introduction of eGFR reporting and CKD QOF domains was associated with a rapid 61% increase in new patient referral, and an increase in the mean age of the patients at referral from 63.0 +/- 18.1 to 69.1 +/- 18.5. The referrals did not correlate with the QOF reported prevalence of CKD. Systematic screening of new referrals demonstrated 36% to be either inappropriate or inadequate in terms of clinical information supplied. Introduction of the renal patient care pathway was associated with a fall in both the number of inadequate and total new referrals received. Overall 62% of all primary care practices registered with the Map of Medicine(R) and these sent a higher proportion of appropriate referrals and were less likely to generate referrals with inadequate information. The initiative also enabled managed discharges from secondary to primary care settings, freeing up outpatient capacity. The study describes the impact of the introduction eGFR reporting and revision of the GMS contract with Renal QOF, on patient referrals to a nephrology service. In addition, we provide evidence that a new management pathway has helped to regulate and proactively manage the increased demand within the current resources.

Investigating suspected acute pulmonary embolism — what are hospital clinicians thinking?

To assess local clinical knowledge of the appropriate investigation of suspected acute pulmonary embolism (PE) and this compare with the 2003 British Thoracic Society (BTS) guidelines as a national reference standard. A clinical questionnaire was produced based on the BTS guidelines. One hundred and eight-six participants completed the questionnaires at educational sessions for clinicians of all grades, within a single NHS Trust. The level of experience amongst participants ranged from final year medical students to consultant physicians. The clinicians were divided into four groups based on seniority: Pre-registration, Junior, Middle, and Senior. Forty-six point eight percent of all the clinicians correctly identified three major risk factors for PE and 25.8% recognized the definition of the recommended clinical probability score from two alternatives. Statements regarding the sensitivity of isotope lung imaging and computed tomography pulmonary angiography (CTPA) received correct responses from 41.4 and 43% of participants, respectively, whilst 81.2% recognized that an indeterminate ventilation-perfusion scintigraphy (V/Q) study requires further imaging. The majority of clinicians correctly answered three clinical scenario questions regarding use of D-dimers and imaging (78, 85, and 57.5%). There was no statistically significant difference between the four groups for any of the eight questions. The recommended clinical probability score was unfamiliar to all four groups of clinicians in the present study, and the majority of doctors did not agree that a negative CTPA or isotope lung scintigraphy reliably excluded PE. However, questions based on clinical scenarios received considerably higher rates of correct responses. The results indicate that various aspects of the national guidelines on suspected acute pulmonary embolism are unfamiliar to many UK hospital clinicians. Further research is needed to identify methods to improve this situation, as both clinicians and radiologists have a duty to ensure that patients are appropriately investigated.

The Impact of an Out-Reach Clinic on Referral of Patients with Renal Impairment

Background: Early diagnosis and prompt treatment of a number of renal diseases may delay renal failure, obviate the need for renal replacement therapy and reduce co-morbidity. The aim of this study was to examine the impact of out-reach renal clinics on patterns of referral of patients with renal impairment to a nephrologist. Methods: The number of patients with renal impairment was determined as defined by serum creatinine levels >150 µmol/l in three centres within a single NHS trust over two separate 1-week periods. None of the centres studied has a local nephrologist, however one centre (hospital A) has renal out-reach clinics, another is geographically close to a renal unit (hospital B), while the third unit (hospital C) has no nephrology presence and is geographically furthest from the renal unit. In addition, retrospective as well as follow-up data on the renal function of all patients with renal impairment was collected. Results: In hospital A, there was a lower proportion of patients with unreferred renal impairment than in the other two hospitals. Within the unreferred patient group there were significantly more patients whose renal function improved during the follow-up period. A considerable proportion of patients with documented deterioration in renal function remained unknown to nephrology services 6 months after initial presentation. Other than the presence of an onsite nephrology service, the only other factor found to be significantly different in those patients not referred to nephrologists was age: as in all three centres, those not referred were significantly older. Conclusion: Inequity of access to renal services is an important obstacle to early referral of patients with impaired renal function. Out-reach renal services provide a model which significantly improves referral patterns.

Sales of over-the-counter remedies as an early warning system for winter bed crises

To evaluate the pattern of emergency adult medical admissions during the winter period and the usefulness of sales of over-the-counter cough/cold remedies as a predictor of these. The databases of a single NHS trust acute unit and pharmacy outlets in its catchment area were analyzed retrospectively, comparing numbers of emergency admissions, ICD-10 discharge codes, local electronic point-of-sale (EPOS) and national sales data. Over nine consecutive winter periods from 1992/3, peak admissions always occurred within a defined ten-day period from 29th December to 9th January. Emergency admissions increased significantly during this period (P = 0.0002). Pharmaceutical/retail data were available for three consecutive winters 1998/99, 1999/2000 and 2000/2001, none of which coincided with increased influenza activity nationally. Acute respiratory illness as defined by International Classification of Diseases, 10th edition (ICD-10) discharge coding did not appear to contribute to the increase in admissions at the peak. However, National and Local EPOS sales were positively correlated with admissions and the rate of EPOS sales exceeded an empiric threshold of 1000 units per week two weeks prior to the admissions peak in each year. Emergency admissions over the winter period are increasing and can be expected within a period of only ten days each year. No firm relationship between acute respiratory illness and admissions could be defined but local EPOS data may give up to two weeks warning of the peak in admissions and merits further prospective evaluation.

Natural rubber latex allergy in a health-care population in Wales.

Type 1 natural rubber latex (NRL) allergy prevalence rates quoted vary due to the different populations studied and methodologies used for assessment and investigation of NRL allergy. To investigate the rate of type 1 allergy to NRL in health-care workers (HCWs) in a single NHS trust in Wales. A response rate of 3716 of 5548 (67%) of the employees was obtained with a latex allergy questionnaire administered by the occupational health departments. Type 1 NRL allergy was diagnosed by correlating clinical symptoms, skin prick testing and IgE RAST to latex in the dermatology department. The period prevalence (1998-2001) for type 1 clinical latex allergy in HCWs was 25 of 4439 (0.56%). Of the 25 positive HCWs, 18 (72%) were nurses. The low prevalence rate of type 1 NRL allergy should not lead to underestimating the importance of clinically significant NRL allergy and the risks that need to be minimized.

Exploring inconsistent breastfeeding advice: 1

There is now no doubt that breastfeeding provides health benefits for both infant and mother. Although 68% of all mothers in the UK initiate breastfeeding, only 44% are still breastfeeding at 6weeks (Foster et al, 1997). This large proportion of mothers who discontinue breastfeeding before the infant is 6-weeks old do so at a time when the input from health professionals (midwives and health visitors) is at its greatest. It is recognised that professional support when needed is an important element in successful breastfeeding, but conflicting or inconsistent professional advice and practice appear to remain persistent disadvantages. This series of three articles describes a qualitative study which involved interviewing midwives, health visitors and a group of breastfeeding mothers within a single NHS Trust in the north of England. Framework content analysis was used to analyse the interview data in order to explore the basis and effects of inconsistent breastfeeding advice.

The incidence of pressure sores within a National Health Service Trust hospital during 1991

The prevalence of pressure sores has been frequently reported. However, such measures fail to identify how many patients develop sores, while longitudinal changes in prevalence rates are difficult to interpret. This paper provides the first report of the incidence of pressure sores across the population of a single NHS Trust hospital. During 1991, 360 patients developed sores, an incidence of 4.03 patients per 100 admissions. Within orthopaedic wards, the incidence was higher, with 10.3 patients per 100 admissions developing sores.
