Contextualizing the findings of a systematic review on patient and carer experiences of dementia diagnosis and treatment: a qualitative study

Background

Involving service users in the systematic review process is seen as increasingly important. As systematic reviews often include studies from diverse settings and covering a time span of several decades, involving service users in consideration of applicability to specific populations or settings might make reviews more useful to practitioners and policymakers.

Objectives

To test and contextualize the findings of a systematic review of qualitative studies looking at patient and carer experiences of diagnosis and treatment of dementia.

Methods

Results from the systematic review were discussed in focus groups and semi‐structured interviews with patient, public and professional participants in the South East of England. Analysis was guided by coding frameworks developed from the results of the systematic review.

Participants

We recruited 27 participants, including three people with dementia, 12 carers, six service providers and five older people without dementia.

Results

Findings from the focus groups and interviews were consistent with those from the systematic review and suggest that our review findings were applicable to the local setting. We found some evidence that access to information and diagnostic services had improved but, as in the systematic review, post‐diagnosis support was still often experienced as inadequate.

Conclusions

Focus groups and interviews with service users and their representatives can provide useful contextual information. However, such strategies can require considerable investment of the part of the researcher in terms of time and resources, and more work is needed to refine strategies and establish the benefits for patients and the organization of services.     

Care planning for long‐term conditions – a concept mapping

Objective

This article focuses on approaches within clinical practice that seek to actively involve patients with long‐term conditions (LTCs) and how professionals may understand and implement them. Personalized care planning is one such approach, but its current lack of conceptual clarity might have impeded its widespread implementation to date. A variety of overlapping concepts coexist in the literature, which have the potential to impair both clinical and research agendas. The aim of this article is therefore to explore the meaning of the concept of care planning in relation to other overlapping concepts and how this translates into clinical practice implementation.

Methods

Searches were conducted in the Cochrane database for systematic reviews, CINHAL and MEDLINE. A staged approach to conducting the concept mapping was undertaken, by (i) an examination of the literature on care planning in LTCs; (ii) identification of related terms; (iii) locating reviews of those terms. Retrieved articles were subjected to a content analysis, which formed the basis of our concept maps. (iv) We then appraised these against knowledge and experience of the implementation of care planning in clinical practice.

Results and Conclusions

Thirteen articles were retrieved, in which the core importance of patient‐centredness, shared decision making and self‐management was highlighted. Literature searches on these terms retrieved a further 24 articles. Our concept mapping exercise shows that whilst there are common themes across the concepts, the differences between them reflect the context and intended outcomes within clinical practice. We argue that this clarification exercise will allow for further development of both research and clinical implementation agendas.     

Effects of intravenously administered propranolol on wall motion abnormalities

Although propranolol is frequently utilized as therapy for angina pectoris in patients with previous myocardial infarction, its effects on wall motion abnormalities in such patients have not been adequately defined. Accordingly, using external wall motion video tracking, we studied 18 patients with previous myocardial infarction and wall motion disorders and 5 normal subjects before and after administration of propranolol, 5 mg intravenously. Systolic time intervals, heart rate and left heart size (measured by the distance between the mid-line and left heart border in an X-ray film triggered at end-diastole after a standard inspiration) were also measured before and after administration of propranolol. In each instance propranolol produced a reduction in the amplitude and velocity of wall motion in areas of normal movement, hypokinesis and paradox, resulting in decreased outward bulging. In the normal subjects, the amplitude and velocity of wall motion also decreased. In the patients with previous myocardial infarction, propranolol increased the ratio of the preejection period to the left ventricular ejection time from a mean of 0.377 ± 0.03 (standard error of the mean) to 0.409 ± 0.03 (P <0.001); decreased heart rate by an average of 7.5 beats/min (P <0.001); and increased the distance from the mid-line to the left heart border from 94.3 ± 2.6 to 97.3 ± 2.6 mm (P <0.001). Similar changes occurred in the 5 normal subjects. We conclude that doses of propranolol sufficient to increase the ratio of the preejection period to left ventricular ejection time, decrease heart rate and increase heart size do not exaggerate preexisting paradoxical wall motion or accentuate latent areas of paradox in patients with previous myocardial infarction.     

A Preliminary Study of Hepatitis B Virus Replication during Short-Term (7-Day) Social Drinking

The purpose of this study is to determine the effect of short-term social drinking on hepatitis B virus (HBV) replication as measured by serum levels of hepatitis B virus DNA (HBV-DNA). We studied five male carriers of hepatitis B e antigen who were social drinkers. Levels of HBV-DNA, blood alcohol, and aspartate aminotransferase (AST) were measured during abstinence from alcohol, before and during a test dose (29.8 g) of alcohol which followed one week of abstinence, and before and during the same test dose which followed social drinking for one week. We observed no significant changes in HBV-DNA or AST levels. These data suggest that a single one-week period of social drinking in patients with chronic HBV infection does not cause enhanced viral replication. The risks of repeated ingestion of moderate amounts of alcohol by such patients have not been established. Interpretation of our data is limited by the small number of subjects, and further studies are needed. Nevertheless, our results are consistent with published recommendations that social drinking by nonalcoholic HBV carriers should be restricted but need not be totally forbidden.     

The gastrointestinal tract in uremia

Gastrointestinal mucosal abnormalities ranging from edema to ulceration occur in two thirds of patients dying of uremia. Early studies suggested that uremic patients on maintenance dialysis treatment were at increased risk of peptic ulceration but more recent data indicate that this is not so. Other gastrointestinal problems reported for uremic subjects on maintenance dialysis treatment include bleeding from telangiectatic lesions, constipation, mucosal deposition of amyloid and acute pancreatitis. Nausea and vomiting are common in the uremic patient but gastric emptying studies have yielded conflicting results. Patients undergoing renal transplantation are at increased risk of development of esophagitis, complicated peptic ulcer, intestinal ulceration, and perforation as well as acute pancreatitis.     

T Lymphocyte Subsets in Parenteral and Non-parenteral Heroin Abusers in Britain

Parenteral drug abusers comprise the second largest group of patients with the acquired immune deficiency syndrome (AIDS). To determine whether heroin abusers in Britain had immunologic abnormalities similar to those seen in AIDS, we determined T lymphocyte subsets in 14 parenteral heroin abusers and 10 non-parenteral heroin abusers. No significant differences were found in T4/T8 ratios or in the absolute numbers of T3, T4, or T8-positive cells. These results suggest that neither narcotic drugs nor repeated exposure to unsterile injectable substances are responsible for low T4/T8 ratios in parenteral drug abusers with AIDS.
