We explored the association between education and academic ability in childhood and both outpatient appointments and hospital admissions in adulthood, accounting for adult factors, including long-term conditions. The analytical sample consisted of 7183 participants in the Aberdeen Children of the 1950s. Three outcomes were measured using routine Scottish medical records over a five-year period (2004-2008): (1) ≥5 outpatient appointments, (2) ≥2 hospital admissions, or (3) ≥3 outpatient appointments plus ≥1 hospital admission.

Background: Cognitive impairment is prevalent in individuals with chronic kidney disease (CKD), but its effects on health outcomes remain unclear. While cognitive impairment can affect self-management, its role in CKD has been insufficiently explored. This systematic review aimed to examine the association between cognitive impairment and health outcomes or self-management ability among persons with CKD.

Background: Chronic kidney disease (CKD) carries a variable risk for multiple adverse outcomes, highlighting the need for a personalised approach. This study evaluated several novel biomarkers linked to key disease mechanisms to predict the risk of kidney failure (first event of eGFR <15 ml/min/1.73m2 or kidney replacement therapy), all-cause mortality, and a composite of both.

Introduction: Reducing polypharmacy and overprescribing in older people living with frailty is challenging. Evidence suggests that this could be facilitated by structured medication review (SMR) and deprescribing processes involving the multidisciplinary team (MDT). This study aimed to develop an MDT SMR and deprescribing intervention in primary care for older people living with frailty.

Background: Living with multiple long-term conditions (MLTCs) involves 'work'. A recent qualitative synthesis identified eight patient-centred work themes: 'learning and adapting', 'accumulation and complexity', 'investigation and monitoring', 'health service and administration' and 'symptom', 'emotional', 'medication' and 'financial' work. These themes may be underrepresented in electronic health records (EHRs).

Background: Multiple long-term conditions (MLTCs), living with two or more long-term conditions (LTCs), often termed multimorbidity, has a high and increasing prevalence globally with earlier age of onset in people living in deprived communities. A holistic understanding of the patient's perspective of the work associated with living with MLTCs is needed. This study aimed to synthesise qualitative evidence describing the experiences of people living with MLTCs (multimorbidity) and to develop a greater understanding of the effect on people's lives and ways in which living with MLTCs is 'burdensome' for people.

Article Synopsis
  • The study evaluates risks associated with Chronic Kidney Disease (CKD) across different primary renal diseases using data from a UK cohort of nearly 3,000 adults.
  • It found that over a median follow-up of about 49 months, many participants experienced kidney failure or death, with significant differences in risk based on the primary renal diagnosis (PRD), even after adjusting for factors like age and blood pressure.
  • The research highlights that while eGFR is a reliable predictor of kidney outcomes, the effectiveness of albuminuria (uACR) as a predictive marker varies greatly depending on the type of kidney disease, suggesting that personalized treatment strategies are essential in CKD management.

Prospective cohort studies of kidney equity are limited by a focus on advanced rather than early disease and selective recruitment. Whole population studies frequently rely on area-level measures of deprivation as opposed to individual measures of social disadvantage. Here, we linked kidney health and individual census records in the North of Scotland (Grampian area), 2011-2021 (GLOMMS-CORE) and identified incident kidney presentations at thresholds of estimated glomerular filtration rate (eGFR) under 60 (mild/early), under 45 (moderate), under 30 ml/min/1.

Purpose Of Review: With ageing populations and rising prevalence of key risk factors, the prevalence of many long-term conditions including chronic kidney disease (CKD) is increasing globally. Health-related quality of life (HRQoL) is important to people living with CKD but not all HRQoL determinants are modifiable. This review summarizes recently identified potentially modifiable factors affecting HRQoL for people with CKD and recent trials incorporating HRQoL as an outcome.

Article Synopsis
  • The study examines factors affecting health-related quality of life (HRQoL) in patients with chronic kidney disease (CKD), focusing on potentially modifiable aspects that could be targeted for improvement.
  • Researchers analyzed data from nearly 3000 CKD patients, collecting diverse information and using specific measures to assess HRQoL, finding that a significant percentage reported issues in various life dimensions.
  • Results indicated that poorer HRQoL was strongly associated with obesity, depression, anxiety, medication burden, sarcopenia, low hemoglobin levels, and pain, highlighting areas for potential intervention.

Background: A third of older people take five or more regular medications (polypharmacy). Conducting medication reviews in primary care is key to identify and reduce/ stop inappropriate medications (deprescribing). Recent recommendations for effective deprescribing include shared-decision making and a multidisciplinary approach.

Background: Quality of life (QoL) is an important measure of disease burden and general health perception. The relationship between early chronic kidney disease (CKD) and QoL remains poorly understood. The Oxford Renal Study (OxRen) cohort comprises 1063 adults aged ≥60 years from UK primary care practices screened for early CKD, grouped according to existing or screen-detected CKD diagnoses, or biochemistry results indicative of reduced renal function (referred to as transient estimated glomerular filtration rate (eGFR) reduction).

Background: Treatment burden is the effort required of patients to look after their health and the impact this has on their functioning and wellbeing. It is likely treatment burden changes over time as circumstances change for patients and health services. However, there are a lack of population-level studies of treatment burden change and factors associated with this change over time.
