Women’s experiences of anal incontinence following vaginal birth: A qualitative study of missed opportunities in routine care contacts
Objectives This study aimed to explore experiences of women with anal incontinence following a childbirth injury, and to identify areas of missed opportunities within care they received. Design This is a qualitative study involving semi-structured interviews. Setting Participants were recruited via five hospitals in the UK, and via social media adverts and communication from charity organisations. Participants Women who have experienced anal incontinence following a childbirth injury, either within 7 years of sustaining the injury, or if they identified new, or worsening symptoms of AI at the time of menopause. Main outcome measures Main outcomes are experiences of women with anal incontinence following childbirth injury, and missed opportunities within the care they received. Results The following main themes were identified: opportunities for diagnosis missed, missed opportunities for information sharing and continuity and timeliness of care. Conclusions Anal Incontinence following a childbirth injury has a profound impact on women. Lack of information and awareness both amongst women and healthcare professionals contributes to delays in accurate diagnosis and appropriate treatment.
Developing prediction models for electrolyte abnormalities in patients indicated for antihypertensive therapy: evidence-based treatment and monitoring recommendations.
OBJECTIVES: Evidence from clinical trials suggests that antihypertensive treatment is associated with an increased risk of common electrolyte abnormalities. We aimed to develop and validate two clinical prediction models to estimate the risk of hyperkalaemia and hyponatraemia, respectively, to facilitate targeted treatment and monitoring strategies for individuals indicated for antihypertensive therapy. DESIGN AND METHODS: Participants aged at least 40 years, registered to an English primary care practice within the Clinical Practice Research Datalink (CPRD), with a systolic blood pressure reading between 130 and 179 mmHg were included the study. The primary outcomes were first hyperkalaemia or hyponatraemia event recorded in primary or secondary care. Model development used a Fine-Gray approach with death from other causes as competing event. Model performance was assessed using C-statistic, D-statistic, and Observed/Expected (O/E) ratio upon external validation. RESULTS: The development cohort included 1 773 224 patients (mean age 59 years, median follow-up 6 years). The hyperkalaemia model contained 23 predictors and the hyponatraemia model contained 29 predictors, with all antihypertensive medications associated with the outcomes. Upon external validation in a cohort of 3 805 366 patients, both models calibrated well (O/E ratio: hyperkalaemia 1.16, 95% CI 1.13-1.19; hyponatraemia 1.00, 95% CI 0.98-1.02) and showed good discrimination at 10 years (C-statistic: 0.69, 95% CI 0.69-0.69; 0.80, 95% CI 0.80-0.80, respectively). CONCLUSION: Current clinical guidelines recommend monitoring serum electrolytes after initiating antihypertensive treatment. These clinical prediction models predicted individuals' risk of electrolyte abnormalities associated with antihypertensive treatment and could be used to target closer monitoring for individuals at a higher risk, where resources are limited.
Withdrawal of antihypertensive drugs in older people
Background: Hypertension is an important risk factor for subsequent cardiovascular events, including ischaemic and haemorrhagic stroke, myocardial infarction, and heart failure, as well as chronic kidney disease, cognitive decline, and premature death. Overall, the use of antihypertensive medications has led to a reduction in cardiovascular disease, morbidity rates, and mortality rates. However, the use of antihypertensive medications is also associated with harms, especially in older people, including the development of adverse drug reactions and drug-drug interactions, and can contribute to increasing medication-related burden. As such, discontinuation of antihypertensives may be considered appropriate in some older people. Objectives: To evaluate the effects of withdrawal of antihypertensive medications used for hypertension or primary prevention of cardiovascular disease in older adults. Search methods: For this update, we searched the Cochrane Hypertension Specialised Register, CENTRAL (2022, Issue 9), Ovid MEDLINE, Ovid Embase, the WHO ICTRP, and ClinicalTrials.gov up to October 2022. We also conducted reference checking and citation searches, and contacted study authors to identify any additional studies when appropriate. There were no language restrictions on the searches. Selection criteria: We included randomised controlled trials (RCTs) of withdrawal versus continuation of antihypertensive medications used for hypertension or primary prevention of cardiovascular disease in older adults (defined as 50 years of age and over). Eligible participants were living in the community, residential aged care facilities, or based in hospital settings. We included trials evaluating the complete withdrawal of all antihypertensive medication, as well as those focusing on a dose reduction of antihypertensive medication. Data collection and analysis: We compared the intervention of discontinuing or reducing the dose of antihypertensive medication to continuing antihypertensive medication using mean differences (MD) and 95% confidence intervals (95% CIs) for continuous variables, and Peto odds ratios (ORs) and 95% CI for binary variables. Our primary outcomes were mortality, myocardial infarction, and the development of adverse drug reactions or adverse drug withdrawal reactions. Secondary outcomes included hospitalisation, stroke, blood pressure (systolic and diastolic), falls, quality of life, and success in withdrawing from antihypertensives. Two review authors independently, and in duplicate, conducted all stages of study selection, data extraction, and quality assessment. Main results: We identified no new studies in this update. Six RCTs from the original review met the inclusion criteria and were included in the review (1073 participants). Study duration and follow-up ranged from 4 weeks to 56 weeks. Meta-analysis of studies showed that discontinuing antihypertensives, compared to continuing, may result in little to no difference in all-cause mortality (OR 2.08, 95% CI 0.79 to 5.46; P = 0.14, I2 = 0%; 4 studies, 630 participants; low certainty of evidence), and that the evidence is very uncertain about the effect on myocardial infarction (OR 1.86, 95% CI 0.19 to 17.98; P = 0.59, I2 = 0%; 2 studies, 447 participants; very low certainty of evidence). Meta-analysis was not possible for the development of adverse drug reactions and withdrawal reactions; the evidence is very uncertain about the effect of antihypertensive discontinuation on the risk of adverse drug reactions (very low certainty of evidence), and the included studies did not assess adverse drug withdrawal reactions specifically. One study reported on hospitalisations; discontinuing antihypertensives may result in little to no difference in hospitalisation (OR 0.83, 95% CI 0.33 to 2.10; P = 0.70; 1 study, 385 participants; low certainty of evidence). Meta-analysis showed that discontinuing antihypertensives may result in little to no difference in stroke (OR 1.44, 95% CI 0.25 to 8.35; P = 0.68, I2 = 6%; 3 studies, 524 participants; low certainty of evidence). Blood pressure may be higher in the discontinuation group than the continuation group (systolic blood pressure: MD 9.75 mmHg, 95% CI 7.33 to 12.18; P < 0.001, I2 = 67%; 5 studies, 767 participants; low certainty of evidence; and diastolic blood pressure: MD 3.5 mmHg, 95% CI 1.82 to 5.18; P < 0.001, I2 = 47%; 5 studies, 768 participants; low certainty of evidence). No studies reported falls. The sources of bias included selective reporting (reporting bias), lack of blinding of outcome assessment (detection bias), incomplete outcome data (attrition bias), and lack of blinding of participants and personnel (performance bias). Authors' conclusions: The main conclusions from the 2020 review still apply. Discontinuing antihypertensives may result in little to no difference in mortality, hospitalisation, and stroke. The evidence is very uncertain about the effect of discontinuing antihypertensives on myocardial infarction and adverse drug reactions and adverse drug withdrawal reactions. Discontinuing antihypertensives may result in an increase in blood pressure. There was no information about the effect on falls. The evidence was of low to very low certainty, mainly due to small studies and low event rates. These limitations mean that we cannot draw any firm conclusions about the effect of deprescribing antihypertensives on these outcomes. Future research should focus on populations with the greatest uncertainty of the benefit:risk ratio for the use of antihypertensive medications, such as those with frailty, older age groups, and those taking polypharmacy, and measure clinically important outcomes such as adverse drug events, falls, and quality of life.
A mixed methods realist evaluation of a Digital Life Story Work platform: What works, for whom, under what circumstances and how?
Abstract Life Story Work is a fundamental in children’s state care. It is a process of helping children make sense of their experiences to promote their well-being. As society increasingly uses online repositories to store digital artefacts, interest in commissioning Digital Life Story Work (DLSW) platforms grows. However, why, how, when, for whom, and in what circumstances such platforms may help support children with experience of living in state care is unknown. Addressing this gap, we report on the first widespread rollout of a DLSW platform across one English Local Authority. Utilizing a participatory realist evaluation approach, we collected data from 119 participants and involved peer-researchers throughout. This article presents our final programme theory. This illustrates that DLSW is more likely to be optimal when it is: flexible and person-centred; provides future storytelling prompts; starts early; begins in the present; involves children, and constantly offers participation choices; records all aspects of everyday experiences and; when appropriate training and support is available. Findings provide key considerations for commissioners and implementers and begin to build a picture of how DLSW platforms may become embedded in supporting children with experience of living in state care.
