Abstract
BACKGROUND Adherence to complex regimens for people with chronic kidney disease (CKD) and diabetes is often poor. Interventions to enhance adherence require intensive education and behavioural counselling. However, whether the existing evidence is scientifically rigorous and can support recommendations for routine use of educational programmes in people with CKD and diabetes is still unknown. This is an update of a review first published in 2011. OBJECTIVES To evaluate the benefits and harms of education programmes for people with CKD and diabetes. SEARCH METHODS We searched the Cochrane Kidney and Transplant Register of Studies up to 19 July 2024 using search terms relevant to this review. Studies in the Register are identified through searches of CENTRAL, MEDLINE, and EMBASE, conference proceedings, the International Clinical Trials Registry Platform (ICTRP) Search Portal, and ClinicalTrials.gov. SELECTION CRITERIA We included randomised controlled trials (RCTs) and quasi-RCTs investigating the benefits and harms of educational programmes (information and behavioural instructions and advice given by a healthcare provider, who could be a nurse, pharmacist, educator, health professional, medical practitioner, or healthcare provider, through verbal, written, audio-recording, or computer-aided modalities) for people 18 years and older with CKD and diabetes. DATA COLLECTION AND ANALYSIS Two authors independently screened the literature, determined study eligibility, assessed quality, and extracted and entered data. We expressed dichotomous outcomes as risk ratios (RR) with 95% confidence intervals (CI) and continuous data as mean difference (MD) with 95% CI. Data were pooled using the random-effects model. The certainty of the evidence was assessed using the Grades of Recommendation, Assessment, Development and Evaluation (GRADE) approach. MAIN RESULTS Eight studies (13 reports, 840 randomised participants) were included. The overall risk of bias was low for objective outcomes and attrition bias, unclear for selection bias, reporting bias and other biases, and high for subjective outcomes. Education programmes compared to routine care alone probably decrease glycated haemoglobin (HbA1c) (4 studies, 467 participants: MD -0.42%, 95% CI -0.53 to -0.31; moderate certainty evidence; 13.5 months follow-up) and may decrease total cholesterol (179 participants: MD -0.35 mmol/L, 95% CI -0.63 to -00.07; low certainty evidence) and low-density lipoprotein (LDL) cholesterol (179 participants: MD -0.40 mmol/L, 95% CI -0.65 to -0.14; low certainty evidence) at 18 months of follow-up. One study (83 participants) reported education programmes for people receiving dialysis who have diabetes may improve the diabetes knowledge of diagnosis, monitoring, hypoglycaemia, hyperglycaemia, medication with insulin, oral medication, personal health habits, diet, exercise, chronic complications, and living with diabetes and coping with stress (all low certainty evidence). There may be an improvement in the general knowledge of diabetes at the end of the intervention and at the end of the three-month follow-up (one study, 97 participants; low certainty evidence) in people with diabetes and moderately increased albuminuria (A2). In participants with diabetes and moderately increased albuminuria (A2) (one study, 97 participants), education programmes may improve a participant's beliefs in treatment effectiveness and total self-efficacy at the end of five weeks compared to routine care (low certainty evidence). Self-efficacy for in-home blood glucose monitoring and beliefs in personal control may increase at the end of the three-month follow-up (low certainty evidence). There were no differences in other self-efficacy measures. One study (100 participants) reported an education programme may increase change in behaviour for general diet, specific diet and home blood glucose monitoring at the end of treatment (low certainty evidence); however, at the end of three months of follow-up, there may be no difference in any behaviour change outcomes (all low certainty evidence). There were uncertain effects on death, serious hypoglycaemia, and kidney failure due to very low certainty evidence. No data was available for changes in kidney function (creatinine clearance, serum creatinine, doubling of serum creatinine or proteinuria). For an education programme plus multidisciplinary, co-ordinated care compared to routine care, there may be little or no difference in HbA1c, kidney failure, estimated glomerular filtration rate (eGFR), systolic or diastolic blood pressure, hypoglycaemia, hyperglycaemia, and LDL and high-density lipoprotein (HDL) cholesterol (all low certainty evidence in participants with type-2 diabetes mellitus and documented advanced diabetic nephropathy). There were no data for death, patient-orientated measures, change in kidney function (other than eGFR and albuminuria), cardiovascular disease morbidity, quality of life, or adverse events. AUTHORS' CONCLUSIONS Education programmes may improve knowledge of some areas related to diabetes care and some self-management practices. Education programmes probably decrease HbA1c in people with CKD and diabetes, but the effect on other clinical outcomes is unclear. This review only included eight studies with small sample sizes. Therefore, more randomised studies are needed to examine the efficacy of education programmes on important clinical outcomes in people with CKD and diabetes.

Compliance with Prescription Guidelines for Glucose-Lowering Therapies According to Renal Function: Real-Life Study in Inpatients of Internal Medicine, Endocrinology and Cardiology Units. Medicina (B Aires) 2021; 57:medicina57121376. [PMID: 34946320 PMCID: PMC8704212 DOI: 10.3390/medicina57121376] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/27/2021] [Revised: 12/13/2021] [Accepted: 12/16/2021] [Indexed: 12/19/2022] Open
Abstract
Background and objectives: Renal failure is a contraindication for some glucose-lowering drugs and requires dosage adjustment for others, particularly biguanides, sulfonylureas, and inhibitors of dipeptidyl peptidase 4. In this study, we assessed adherence to prescription recommendations for glucose-lowering drugs according to renal function in hospitalized diabetic subjects. Materials and Methods: This prospective cohort study was carried out over a 2-year period in a university hospital. Glomerular filtration rate (GFR) was determined by averaging all measurements performed during hospitalization. Glucose-lowering drug dosages were analyzed according to the recommendations of the relevant medical societies. Results: In total, 2071 diabetic patients (53% hospitalized in cardiology units) were examined. GFR was <30 mL/min/1.73 m2 in 13.4% of these patients, 30–44 in 15.1%, 45–60 in 18.3%, and >60 in 53.3%. Inappropriate oral glucose-lowering treatments were administered to 273 (13.2%) patients, including 53 (2.6%) with a contraindication. In cardiology units, 53.1% and 14.3% of patients had GFRs of <60 and <30 mL/min/1.73 m2, respectively, and 179 (15.4%) patients had a contraindication or were prescribed an excessive dose of glucose-lowering drugs. Conclusions: We showed that the burden of inappropriate prescriptions is high in diabetic patients. Given the high number of patients receiving these medications, particularly in cardiology units, a search for potential adverse effects related to these drugs should be performed.

First trimester fasting glucose and glycated haemoglobin cut-offs associated with abnormal glucose homeostasis in the post-partum reclassification in women with hyperglycaemia in pregnancy. Arch Gynecol Obstet 2021; 305:475-482. [PMID: 34104979 DOI: 10.1007/s00404-021-06107-6] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2021] [Accepted: 05/22/2021] [Indexed: 01/28/2023]
Abstract
Hyperglycaemia first detected during pregnancy is either gestational diabetes mellitus (GDM) or previous undiagnosed diabetes. We aimed to study if there were a first trimester fasting glycaemia (FTG) and a glycated haemoglobin (HbA1c) cut-off values associated with type 2 diabetes mellitus (T2DM) or abnormal glucose homeostasis (AGH) at the post-partum oral glucose tolerance test (OGTT) reclassification. We retrospectively studied a group of pregnant women from the Portuguese National Registry of GDM. Receiver-operating characteristic (ROC) curves were used to determine the best FTG and HbA1c cut-offs to predict T2DM and AGH. We studied 4068 women. The area under the ROC curves (AUC) for the association with T2DM was 0.85 (0.80-0.90) for FTG and 0.85 (0.80-0.91) for HbA1c. The best FTG cut-off for association with T2DM was 99 mg/dL: sensitivity 77.4%, specificity 74.3%, positive predictive value (PPV) 4.8%, and negative predictive value (NPV) 99.5%. The best HbA1c cut-off for association with T2DM was 5.4%: sensitivity 79.0%, specificity 80.1%, PPV 5.7%, and NPV 99.6%. The AUC for the association of FTG and HbA1c with AGH were 0.73 (0.70-0.76) and 0.71 (0.67-0.74), respectively. The best FTG cut-off for predicting AGH was 99 mg/dL: sensitivity 59.4%, specificity 76.2%, PPV 17.0%, and NPV 95.8%. The best HbA1c cut-off was 5.4%: sensitivity 48.7%, specificity 81.5%, PPV 17.8%, and NPV 95.1%. We suggest an FTG of 99 mg/dL and an HbA1c of 5.4% as the best cut-offs below which T2DM is unlikely to be present. Almost all patients with FTG < 99 mg/dL and HbA1c < 5.4% did not reclassify as T2DM. These early pregnancy cut-offs might alert the physician for the possibility of a previous undiagnosed diabetes and alert them to the importance of testing for it after delivery.

J Diabetes Metab Disord 2020; 19:1473-1481. [PMID: 33520848 PMCID: PMC7843698 DOI: 10.1007/s40200-020-00680-4] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/06/2020] [Revised: 10/07/2020] [Accepted: 10/28/2020] [Indexed: 11/25/2022]
Abstract
BACKGROUND Chronic kidney disease (CKD) is the known cause of morbidity and mortality among diabetes mellitus (DM) patients. Targeted screening of renal impairment based on estimated glomerular filtration rate (eGFR) among DM patients has potential benefits in early identification and treatment of CKD. Hence, this study was aimed to estimate the magnitude of renal impairment using eGFR among type 2 DM patients. METHODS An institution-based cross-sectional study was conducted from February-1 to April 30/2020 among 422 type 2 DM patients in Northeast Ethiopia. Data were collected by the semi-structured questioner and serum creatinine measurement. The collected data were edited into Epi-data manager version 4.4.1.0, and the analysis was performed by SPSS-25. The Simplified Modification of Diet in Renal Disease (MDRD), Chronic Kidney Disease Epidemiology (CKD-EPI), and Cockcroft-Gault (C-G) equations were used to calculate eGFR. RESULTS Of all study participants, 82(19.4%), 92(21.8%), and 103(24.4%) had eGFR < 60 ml/min/1.73 m2, according to the MDRD, CKD-EPI, and C-G equations, respectively. Female sex, (MDRD:AOR = 4.44, 95%CI:1.97-9.97, CKD-EPI:AOR = 3.17, 95%CI:1.27-6.17, and C-G:AOR = 2.65, 95%CI:1.35-5.21), duration ≥ 10 years (MDRD:AOR = 3.38, 95%CI:1.45-7.92, CKD-EPI:AOR = 3.09, 95%CI:1.07-7.77, and C-G:AOR = 2.92, 95%CI:1.29-6.61), age ˃60 years (MDRD:AOR = 2.29, 95%CI:1.09-4.77, CKD-EPI:AOR = 4.12, 95%CI:1.68-6.78, and C-G: AOR = 3.42, 95%CI:1.77-6.60), hypertension (MDRD:AOR = 3.12, 95%CI:1.51-6.45, CKD-EPI: AOR = 4.21,95%CI:2.07-7.98, and C-G:AOR = 3.99, 95%CI:2.08-7.65), poor glycemic control (MDRD:AOR = 2.82, 95%CI:1.13-7.05, and C-G:AOR = 2.34, 95%CI:1.09-5.04), and body mass index (MDRD:AOR = 1.11, 95%CI:1.01-1.22, and CKD-EPI:AOR = 2.43, 95%CI:1.27-5.76) were significantly associated with renal impairment. CONCLUSION Renal impairment was prevalent among type 2 DM patients. Older age, female sex, duration, hypertension, poor glycemic control, and BMI were significantly associated with renal impairment.

Abstract
BACKGROUND Studies have shown unwarranted variation in test ordering among GP practices and regions, which may lead to patient harm and increased health care costs. There is currently no robust evidence base to inform guidelines on monitoring long-term conditions. OBJECTIVES To map the extent and nature of research that provides evidence on the use of laboratory tests to monitor long-term conditions in primary care, and to identify gaps in existing research. METHODS We performed a scoping review-a relatively new approach for mapping research evidence across broad topics-using data abstraction forms and charting data according to a scoping framework. We searched CINAHL, EMBASE and MEDLINE to April 2019. We included studies that aimed to optimize the use of laboratory tests and determine costs, patient harm or variation related to testing in a primary care population with long-term conditions. RESULTS Ninety-four studies were included. Forty percent aimed to describe variation in test ordering and 36% to investigate test performance. Renal function tests (35%), HbA1c (23%) and lipids (17%) were the most studied laboratory tests. Most studies applied a cohort design using routinely collected health care data (49%). We found gaps in research on strategies to optimize test use to improve patient outcomes, optimal testing intervals and patient harms caused by over-testing. CONCLUSIONS Future research needs to address these gaps in evidence. High-level evidence is missing, i.e. randomized controlled trials comparing one monitoring strategy to another or quasi-experimental designs such as interrupted time series analysis if trials are not feasible.

Periodontal Treatment Experience Associated with Oral Health-Related Quality of Life in Patients with Poor Glycemic Control in Type 2 Diabetes: A Case-Control Study. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2019; 16:ijerph16204011. [PMID: 31635118 PMCID: PMC6843950 DOI: 10.3390/ijerph16204011] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/10/2019] [Revised: 10/15/2019] [Accepted: 10/16/2019] [Indexed: 02/06/2023]
Abstract
Severe periodontitis is a risk factor for poor glycemic control. The appropriate medical treatment and plaque control of periodontitis positively affects blood-sugar control in diabetes patients. We aimed to identify the factors associated with glycemic control and examine the periodontal treatment (PT) experience and oral health-related quality of life (OHQoL) for patients with poor glycemic control in type 2 diabetes mellitus (T2DM). This multicenter case–control study recruited 242 patients with poor glycemic control and 198 patients with good glycemic control. We collected patients’ information through face-to-face interviews using a structured questionnaire. The Oral Health Impact Profile-14 (OHIP-14) was used to measure OHQoL. Based on PT status, the patients were classified into three groups: a non-periodontal disease group, a PT group, and a non-PT (NPT) group. Regression models were used to analyze the data. No interdental cleaning (adjusted odds ratio (aOR) = 1.78) and positive attitudes toward periodontal health (aOR = 1.11) were significantly more likely to be associated with poor glycemic control in patients with T2DM. The PT group had a significantly lower OHIP-14 score than the NPT group (6.05 vs. 9.02, p < 0.001), indicating a better OHQoL among patients with poorly controlled T2DM. However, the OHQoL did not differ significantly in patients with well-controlled T2DM between the PT and NPT groups. This suggested that diabetic patients with poor glycemic control must improve periodontal care practices and receive proper PT, if necessary, to improve their OHQoL.

Trends in kidney function testing in UK primary care since the introduction of the quality and outcomes framework: a retrospective cohort study using CPRD. BMJ Open 2019; 9:e028062. [PMID: 31196901 PMCID: PMC6575820 DOI: 10.1136/bmjopen-2018-028062] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/22/2018] [Revised: 05/01/2019] [Accepted: 05/02/2019] [Indexed: 11/03/2022] Open
Abstract
OBJECTIVES To characterise serum creatinine and urinary protein testing in UK general practices from 2005 to 2013 and to examine how the frequency of testing varies across demographic factors, with the presence of chronic conditions and with the prescribing of drugs for which kidney function monitoring is recommended. DESIGN Retrospective open cohort study. SETTING Routinely collected data from 630 UK general practices contributing to the Clinical Practice Research Datalink. PARTICIPANTS 4 573 275 patients aged over 18 years registered at up-to-standard practices between 1 April 2005 and 31 March 2013. At study entry, no patients were kidney transplant donors or recipients, pregnant or on dialysis. PRIMARY OUTCOME MEASURES The rate of serum creatinine and urinary protein testing per year and the percentage of patients with isolated and repeated testing per year. RESULTS The rate of serum creatinine testing increased linearly across all age groups. The rate of proteinuria testing increased sharply in the 2009-2010 financial year but only for patients aged 60 years or over. For patients with established chronic kidney disease (CKD), creatinine testing increased rapidly in 2006-2007 and 2007-2008, and proteinuria testing in 2009-2010, reflecting the introduction of Quality and Outcomes Framework indicators. In adjusted analyses, CKD Read codes were associated with up to a twofold increase in the rate of serum creatinine testing, while other chronic conditions and potentially nephrotoxic drugs were associated with up to a sixfold increase. Regional variation in serum creatinine testing reflected country boundaries. CONCLUSIONS Over a nine-year period, there have been increases in the numbers of patients having kidney function tests annually and in the frequency of testing. Changes in the recommended management of CKD in primary care were the primary determinant, and increases persist even after controlling for demographic and patient-level factors. Future studies should address whether increased testing has led to better outcomes.

Abstract
AIM To examine whether diabetes and the degree of glycaemic control is associated with an increased risk of acute eye infection, and prescribing of ocular antimicrobial agents. DESIGN AND SETTING A retrospective cohort study was carried out using the Royal College of General Practitioners Research and Surveillance Centre database (RCGP RSC), a large primary care database in the United Kingdom. We compared ocular infection rates in people aged ≥15 years without diabetes to those with diabetes, both type 1 and type 2. We developed logistic regression models to assess the excess risk in diabetes of: conjunctivitis, blepharitis, stye/chalzion, periorbital cellulitis, keratitis/keratoconjunctivitis, lacrimal gland infection, endopthalmitis, and ocular antimicrobial prescriptions over a six-year period (2010-2015). We also analysed the impact of glycaemic control on infection rates in those with diabetes. All models were adjusted for potential confounders. RESULTS We analysed infection risk in 889,856 people without diabetes and 48,584 people with diabetes (3273 type 1, and 45,311 type 2). After adjustment for confounders both type 1 and type 2 were associated with increased incidence of conjunctivitis (OR 1.61; 95% CI 1.38-1.88; p<0.0001 and OR 1.11; 95% CI 1.06-1.16; p<0.0001 respectively). No association was found with blepharitis, stye/chalzion, periorbital cellulitis, keratitis/keratoconjunctivitis, lacrimal gland infection, and endopthalmitis in the whole population. In subgroup analyses blepharitis was more common in those with type 1 diabetes under 50 years old and endopthalmitis in those under 50 with type 2 diabetes. Glycaemic control was not found to be associated with any infection. Diabetes was also associated with an increased incidence of antimicrobial prescriptions (Type 1 OR 1.69; 95% CI 1.51-1.88; p<0.0001 and type 2 OR 1.17; 95% CI 1.13-1.20; p<0.0001). CONCLUSIONS Conjunctivitis is recorded more frequently in people with diabetes. However, no substantial increase in recording of other ocular infections was noted. Infection risk was not found to be associated with the degree of glycaemic control.

Abstract
OBJECTIVES This study 1) investigated life expectancy and cause-specific mortality rates associated with type 2 diabetes and 2) quantified these relationships in ethnic subgroups. RESEARCH DESIGN AND METHODS This was a cohort study using Clinical Practice Research Datalink data from 383 general practices in England with linked hospitalization and mortality records. A total of 187,968 patients with incident type 2 diabetes from 1998 to 2015 were matched to 908,016 control subjects. Abridged life tables estimated years of life lost, and a competing risk survival model quantified cause-specific hazard ratios (HRs). RESULTS A total of 40,286 deaths occurred in patients with type 2 diabetes. At age 40, white men with diabetes lost 5 years of life and white women lost 6 years compared with those without diabetes. A loss of between 1 and 2 years was observed for South Asians and blacks with diabetes. At age older than 65 years, South Asians with diabetes had up to 1.1 years' longer life expectancy than South Asians without diabetes. Compared with whites with diabetes, South Asians with diabetes had lower adjusted risks for mortality from cardiovascular (HR 0.82; 95% CI 0.75, 0.89), cancer (HR 0.43; 95% CI 0.36, 0.51), and respiratory diseases (HR 0.60; 95% CI 0.48, 0.76). A similar pattern was observed in blacks with diabetes compared with whites with diabetes. CONCLUSIONS Type 2 diabetes was associated with more years of life lost among whites than among South Asians or blacks, with older South Asians experiencing longer life expectancy compared with South Asians without diabetes. The findings support optimized cardiovascular disease risk factor management, especially in whites with type 2 diabetes.

Real-world evidence studies into treatment adherence, thresholds for intervention and disparities in treatment in people with type 2 diabetes in the UK. BMJ Open 2016; 6:e012801. [PMID: 27884846 PMCID: PMC5168506 DOI: 10.1136/bmjopen-2016-012801] [Citation(s) in RCA: 40] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/24/2016] [Revised: 09/21/2016] [Accepted: 11/03/2016] [Indexed: 01/14/2023] Open
Abstract
PURPOSE The University of Surrey-Lilly Real World Evidence (RWE) diabetes cohort has been established to provide insights into the management of type 2 diabetes mellitus (T2DM). There are 3 areas of study due to be conducted to provide insights into T2DM management: exploration of medication adherence, thresholds for changing diabetes therapies, and ethnicity-related or socioeconomic-related disparities in management. This paper describes the identification of a cohort of people with T2DM which will be used for these analyses, through a case finding algorithm, and describes the characteristics of the identified cohort. PARTICIPANTS A cohort of people with T2DM was identified from the Royal College of General Practitioners Research and Surveillance Centre (RCGP RSC) data set. This data set comprises electronic patient records collected from a nationally distributed sample of 130 primary care practices across England with scope to increase the number of practices to 200. FINDINGS TO DATE A cohort (N=58 717) of adults with T2DM was identified from the RCGP RSC population (N=1 260 761), a crude prevalence of diabetes of 5.8% in the adult population. High data quality within the practice network and an ontological approach to classification resulted in a high level of data completeness in the T2DM cohort; ethnicity identification (82.1%), smoking status (99.3%), alcohol use (93.3%), glycated haemoglobin (HbA1c; 97.9%), body mass index (98.0%), blood pressure (99.4%), cholesterol (87.4%) and renal function (97.8%). Data completeness compares favourably to other, similarly large, observational cohorts. The cohort comprises a distribution of ages, socioeconomic and ethnic backgrounds, diabetes complications, and comorbidities, enabling the planned analyses. FUTURE PLANS Regular data uploads from the RCGP RSC practice network will enable this cohort to be followed prospectively. We will investigate medication adherence, explore thresholds and triggers for changing diabetes therapies, and investigate any ethnicity-related or socioeconomic-related disparities in diabetes management.

PLoS One 2015; 10:e0135947. [PMID: 26317435 PMCID: PMC4552710 DOI: 10.1371/journal.pone.0135947] [Citation(s) in RCA: 65] [Impact Index Per Article: 7.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2015] [Accepted: 07/29/2015] [Indexed: 12/18/2022] Open
Abstract
BACKGROUND Multimorbidity is increasingly prevalent and represents a major challenge in primary care. Patients with multimorbidity are potentially more likely to experience safety incidents due to the complexity of their needs and frequency of their interactions with health services. However, rigorous syntheses of the link between patient safety incidents and multimorbidity are not available. This review examined the relationship between multimorbidity and patient safety incidents in primary care. METHODS We followed our published protocol (PROSPERO registration number: CRD42014007434). Medline, Embase and CINAHL were searched up to May 2015. Study design and quality were assessed. Odds ratios (OR) and 95% confidence intervals (95% CIs) were calculated for the associations between multimorbidity and two categories of patient safety outcomes: 'active patient safety incidents' (such as adverse drug events and medical complications) and 'precursors of safety incidents' (such as prescription errors, medication non-adherence, poor quality of care and diagnostic errors). Meta-analyses using random effects models were undertaken. RESULTS Eighty six relevant comparisons from 75 studies were included in the analysis. Meta-analysis demonstrated that physical-mental multimorbidity was associated with an increased risk for 'active patient safety incidents' (OR = 2.39, 95% CI = 1.40 to 3.38) and 'precursors of safety incidents' (OR = 1.69, 95% CI = 1.36 to 2.03). Physical multimorbidity was associated with an increased risk for active safety incidents (OR = 1.63, 95% CI = 1.45 to 1.80) but was not associated with precursors of safety incidents (OR = 1.02, 95% CI = 0.90 to 1.13). Statistical heterogeneity was high and the methodological quality of the studies was generally low. CONCLUSIONS The association between multimorbidity and patient safety is complex, and varies by type of multimorbidity and type of safety incident. Our analyses suggest that multimorbidity involving mental health may be a key driver of safety incidents, which has important implication for the design and targeting of interventions to improve safety. High quality studies examining the mechanisms of patient safety incidents in patients with multimorbidity are needed, with the goal of promoting effective service delivery and ameliorating threats to safety in this group of patients.

Abstract
Background Chronic kidney disease (CKD) is predominantly managed in primary care in the UK, but there is evidence of under-identification leading to lack of inclusion on practice chronic disease registers, which are necessary to ensure disease monitoring. Guidelines for CKD patients recommend urinary albumin to creatinine ratio (uACR) testing to identify albuminuria to stratify risk and guide management. This study aimed to describe the pattern and associations of timely CKD registration and uACR testing. Methods A retrospective cohort of individuals with incident CKD 3–5 (two estimated glomerular filtration rates (eGFR) <60 ml/min/1.73 m2 ≥ three months apart) between 2007 and 2013 was identified from a linked database containing primary and secondary care data. Descriptive statistics and Cox proportional hazards models were used to identify associations with patient characteristics of timely CKD registration and uACR testing (within a year of first low eGFR). Results 12,988 people with CKD 3–5 were identified from 88 practices and followed for median 3.3 years. During this time period, 3235 (24.9%) were CKD-registered and 4638/12,988 (35.7%) had uACR testing (median time to CKD registration 307 days and to uACR test 379 days). 1829 (14.1%) were CKD-registered and 2229 (17.2%) had uACR testing within one year. Amongst people whose CKD was registered within a year, 676/1829 (37.0%) had uACR testing within a year (vs. 1553/11,159 (13.9%) of those not registered (p < 0.001)). Timely uACR testing varied by year, with a sharp rise in proportion in 2009 (when uACR policy changed). Timely CKD registration was independently associated with lower eGFR, being female, earlier year of joining the cohort, having diabetes, hypertension, or cardiovascular disease but not with age. Timely uACR testing was associated with timely CKD registration, younger age, having diabetes, higher baseline eGFR and later year of joining the cohort. Conclusions Better systems are needed to support timely CKD identification, registration and uACR testing in primary care in order to facilitate risk stratification and appropriate clinical management.

Abstract
Background Autosomal dominant polycystic kidney disease (ADPKD) causes progressive renal damage and is a leading cause of end-stage renal failure. With emerging therapies it is important to devise a method for early detection. We aimed to identify factors from routine clinical data which can be used to distinguish people with a high likelihood of having ADPKD in a primary health care setting. Method A cross-sectional study was undertaken using data from the Quality Intervention in Chronic Kidney Disease trial extracted from 127 primary care practices in England. The health records of 255 people with ADPKD were compared to the general population. Logistic regression was used to identify clinical features which distinguish ADPKD. These clinical features were used to stratify individual risk using a risk score tool. Results Renal impairment, proteinuria, haematuria, a diastolic blood pressure over 90 mmHg and multiple antihypertensive medications were more common in ADPKD than the general population and were used to build a regression model (area under the receiver operating characteristic curve; 0.79). Age, gender, haemoglobin and urinary tract infections were not associated with ADPKD. A risk score (range −3 to +10) of ≥0 gave a sensitivity of 70.2% and specificity 74.9% of for detection. Conclusions Stratification of ADPKD likelihood from routine data may be possible. This approach could be a valuable component of future screening programs although further longitudinal analyses are needed.

Abstract
Percutaneous transluminal renal angioplasty/stenting (PTRAS) is frequently used to treat renal artery stenosis and renovascular disease (RVD); however, renal function is restored in less than one half of the cases. This study was designed to test a novel intervention that could refine PTRAS and enhance renal recovery in RVD. Renal function was quantified in pigs after 6 weeks of chronic RVD (induced by unilateral renal artery stenosis), established renal damage, and hypertension. Pigs with RVD then underwent PTRAS and were randomized into three groups: placebo (RVD+PTRAS), chronic endothelin-A receptor (ET-A) blockade (RVD+PTRAS+ET-A), and chronic dual ET-A/B blockade (RVD+PTRAS+ET-A/B) for 4 weeks. Renal function was again evaluated after treatments, and then, ex vivo studies were performed on the stented kidney. PTRAS resolved renal stenosis, attenuated hypertension, and improved renal function but did not resolve renal microvascular rarefaction, remodeling, or renal fibrosis. ET-A blocker therapy after PTRAS significantly improved hypertension, microvascular rarefaction, and renal injury and led to greater recovery of renal function. Conversely, combined ET-A/B blockade therapy blunted the therapeutic effects of PTRAS alone or PTRAS followed by ET-A blockade. These data suggest that ET-A receptor blockade therapy could serve as a coadjuvant intervention to enhance the outcomes of PTRAS in RVD. These results also suggest that ET-B receptors are important for renal function in RVD and may contribute to recovery after PTRAS. Using clinically available compounds and techniques, our results could contribute to both refinement and design of new therapeutic strategies in chronic RVD.
