Failing to meet the needs of generations of care home residents with diabetes: a review of the literature and a call for action.

In residential care homes and aged-care facilities globally, between one in three and one in four residents may have diabetes, an often complex highly co-morbid illness that leads to frailty, dependency, disability and reduced life expectancy. Residents with diabetes also have a high risk of hypoglycaemia, avoidable hospital admissions, and represent one of the most difficult challenges to health professionals and care staff in optimizing their diabetes and medical care. This detailed review examines the literature relating to care home diabetes over the last 25 years to assess what has been achieved in characterizing residents with diabetes, and what we know about the various but limited intervention studies that have been carried out internationally. The guidance and guidelines that have been published to assist clinicians in planning effective and safe care for this rather vulnerable group of people with diabetes are also reviewed. The review presents the first diagrammatic representation of a likely physiological cascade depicting the mainly irreversible functional decline a resident with diabetes might experience, provides modern principles of care for each resident with diabetes, and identifies what priority recommendations are required to be implemented if diabetes care is to improve. The review concludes that action is required since diabetes care still remains fragmented, sub-optimal, and in need of investment, otherwise care home residents with diabetes will continue to have their needs unfulfilled.

Route to improving Type 1 diabetes mellitus glycaemic outcomes: real-world evidence taken from the National Diabetes Audit.

AIM: To use general practice-level data for England, available through the National Diabetes Audit, and primary care prescribing data to identify prescription treatment factors associated with variations in achieved glucose control (HbA1c ). METHODS: General practice-level National Diabetes Audit data on Type 1 diabetes, including details of population characteristics, services, proportion of people achieving target glycaemic control [HbA1c ≤58 mmol/mol (7.5%)] and proportion of people at high glycaemic risk [HbA1c >86 mmol/ml (10%)], were linked to 2013-2016 primary care diabetes prescribing data on insulin types and blood glucose monitoring for all people with diabetes. RESULTS: A wide variation was found between the 10th percentile and the 90th percentile of general practices in both target glycaemic control (15.6% to 44.8%, respectively) and high glycaemic risk (4.8% to 28.6%, respectively). Our analysis suggests that, given the extrapolated total of 280 000 people with Type 1 diabetes in the UK, there may be the potential to increase the number of those within target glycaemic control from 80 000 to 101 000; 53% of this increase (11 000 people) would result from service improvements and 47% (10 000 people) from medication and technology changes. The same improvements would also provide the opportunity to reduce the number of people at high glycaemic risk from 42 000 to 26 500. A key factor associated with practice-level target HbA1c achievement would be greater use of insulin pumps for up to an additional 56 000 people. CONCLUSION: If the HbA1c achievement rates in service provision, medication and use of technology currently seen in practices in the 90th percentile were to be matched with regard to HbA1c achievement rates in all general practices, glycaemic control might be improved for 36 500 people, with all the attendant health benefits.

Prescribed medicines for elderly frail people with diabetes resident in nursing homes-issues of polypharmacy and medication costs.

AIMS: To describe the numbers and costs of medications prescribed to people living with diabetes resident in nursing homes in one primary care trust in the UK. METHODS: A retrospective case notes review of 75 people with known diabetes who were resident in the 11 nursing homes in the Coventry teaching primary care trust. RESULTS: Sixty-three residents (84%) were being prescribed four or more medications. Forty-four residents (59%) were prescribed anti-platelet drugs for prevention of cardiovascular disease, including aspirin, clopidogrel and dipyridamole, and 31 residents (41%) were on statin therapy. Eighteen (24%) residents had a monthly medication cost that was above £101 per month. On detailed review, these were largely residents who were being prescribed special order liquid preparations, usually for secondary cardiovascular disease prevention. CONCLUSION: Polypharmacy, defined as taking four or more drugs per day per resident, is highly prevalent within this population of care home residents with diabetes. A high proportion of residents are prescribed drugs for cardiovascular disease prevention, which may be entirely inappropriate in this population with limited life expectancy. Regular medication review of care home residents with diabetes should be undertaken as it has the potential to reduce costs, minimize adverse drug reactions and increase health gain.

Setting research priorities for Type 1 diabetes.

AIMS: Research priorities are often set by academic researchers or the pharmaceutical industry. The interests of patients, carers and clinicians may therefore be overlooked and research questions that matter may be neglected. The aims of this study were to collect uncertainties about the treatment of Type 1 diabetes from patients, carers and health professionals, and to collate and prioritize these uncertainties to develop a top 10 list of research priorities, using a structured priority-setting partnership of patients, carers, health professionals and diabetes organizations, as described by the James Lind Alliance. METHODS: A partnership of interested organizations was set up, and from this a steering committee of 10 individuals was formed. An online and paper survey was used to identify uncertainties. These were collated, and the steering group carried out an interim priority-setting exercise with partner organizations. This group of uncertainties was then voted on to give a smaller list that went forward to the final priority-setting workshop. At this meeting, a final list of the top 10 research priorities was agreed. RESULTS: An initial 1141 uncertainties were described. These were reduced to 88 indicative questions, 47 of which went out for voting. Twenty-four were then taken forward to a final priority-setting workshop. This workshop resulted in a list of top 10 research priorities in Type 1 diabetes. CONCLUSION: We have shown that it is possible using the James Lind Alliance process to develop an agreed top 10 list of research priorities for Type 1 diabetes from health professionals, patients and carers.

People living with diabetes resident in nursing homes--assessing levels of disability and nursing needs.

AIMS: To describe the degree of disability and nursing need of people living with diabetes resident in nursing homes in one Primary Care Trust in the UK. METHODS: A retrospective case notes review of 75 people with known diabetes who were resident in the 11 nursing homes in Coventry Teaching Primary Care Trust. RESULTS: Very significant levels of disability and nursing need were documented in areas of continence, feeding, mobility and communication. Each individual had a mean of four co-morbidities (range 1-8), excluding diabetes. Using the definition of terminal illness based on a negative answer to the question 'would I be surprised if my patient were to die in the next 12 months' it is likely that the majority of individuals described in this study would be classified as being terminally ill. CONCLUSION: Using four practical clinical measures, this study has shown very significant levels of disability and nursing care need in this population of mainly elderly people resident in nursing homes in Coventry. In addition, it has demonstrated that a large proportion of nursing home residents with diabetes can be considered to be in the terminal phase of life, a period where many other factors interplay in how care should be delivered and what outcomes are appropriate. In fact, residents in this category may well be candidates for a considered withdrawal of treatments, but not of care.

Medical information about diabetes--how to keep up to date.

Diabet. Med. 27, 1335-1340 (2010) ABSTRACT: There is a vast amount of new medical information published on diabetes each year; the number of systematic reviews on diabetes is also increasing rapidly. It is therefore difficult for clinicians keep up to date with the new evidence. It is suggested that reading the full National Institute for Clinical Excellence (NICE) guidelines on diabetes will bring you up to date with information as at the date of the evidence cut-off, which is usually approximately 1 year before publication. Also regularly visiting 'NHS Evidence--diabetes', an online resource that offers a foraging service, surveying the literature and alerting clinicians to all the new important and useful information, enables the busy clinician to manage information overload and help keep up to date.

People with Type Diabetes Mellitus (T1DM) self-reported views on their own condition management reveal links to potentially improved outcomes and potential areas for service improvement.

BACKGROUND: The self-management of type 1 diabetes (T1DM) has moved forward in many areas over the last 40 years. Our study asked people with T1DM what is their experience of blood glucose (BG) monitoring day to day and how this influences decisions about insulin dosing. METHODS: An on-line self-reported questionnaire containing 44 questions prepared after consultation with clinicians and patients was circulated to people with T1DM 116 responders provided completed responses. Fixed responses were allocated specific values (e.g. not confident = 0 fairly confident = 1). Multivariate regression analysis was carried out. Only those 5 factors with p-value <0.05 were retained. RESULTS: 59% of respondents were >50 years old and 66% had diabetes for >20 years, with 63% of patients reporting HbA1c results ≤8% or 64 mmol/mol. Findings included; 75% used only 1 m; 56% had used the same meter for ≥3 years; 10% had tried flash monitors; 47% were concerned about current BG level; 85% were concerned about long-term impact of higher BG. 72% of respondents keep BG level high to avoid hypoglycaemia; 25% used ≥7 mmol/L as pre-meal BG target to calculate dose; 65% were concerned they might be over/under-dosing; 83% did not discuss accuracy when choosing meter. However 85% were confident in their meter's performance. The factors that linked to LOWER HbA1c included LESS units of basal insulin (p < 0.001), HIGHER number of daily BG tests (p = 0.008), LOWER bedtime blood glucose (p = 0.009), HIGHER patient's concern over long-term impact of high BG (BG) (p < 0.009 but LOWER patient's concern over current BG values (p = 0.009). The final statistical model could explain 41% of the observed variation in HbA1c. CONCLUSION: Many people still run their BG high to avoid hypoglycaemia. Concern about the longer-term consequences of suboptimal glycaemic control was associated with a lower HbA1c and is an area to explore in the future when considering how to help people with T1DM.

Minimising metabolic and cardiovascular risk in schizophrenia: diabetes, obesity and dyslipidaemia.

People with schizophrenia are at greater risk of obesity, Type 2 diabetes, dyslipidaemia and hypertension than the general population. This results in an increased incidence of cardiovascular disease (CVD) and reduced life expectancy, over and above that imposed by their mental illness through suicide. Several levels of evidence from data linkage analyses to clinical trials demonstrate that treatment-related metabolic disturbances are commonplace in this patient group, and that the use of certain second-generation antipsychotics may compound the risk of developing the metabolic syndrome and CVD. In addition, smoking, poor diet, reduced physical activity and alcohol or drug abuse are prevalent in people with schizophrenia and contribute to the overall CVD risk. Management and minimization of metabolic risk factors are pertinent when providing optimal care to patients with schizophrenia. This review recommends a framework for the assessment, monitoring and management of patients with schizophrenia in the UK clinical setting.

A series of systematic reviews to inform a decision analysis for sampling and treating infected diabetic foot ulcers.

OBJECTIVES: To review systematically the evidence on the performance of diagnostic tests used to identify infection in diabetic foot ulcers (DFUs) and of interventions to treat infected DFUs. To use estimates derived from the systematic reviews to create a decision analytic model in order to identify the most effective method of diagnosing and treating infection and to identify areas of research that would lead to large reductions in clinical uncertainty. DATA SOURCES: Electronic databases covering period from inception of the database to November 2002. REVIEW METHODS: Selected studies were assessed against validated criteria and described in a narrative review. The structure of a decision analytic model was derived for two groups of patients in whom diagnostic tests were likely to be used. RESULTS: Three studies that investigated the performance of diagnostic tests for infection on populations including people with DFUs found that there was no evidence that single items on a clinical examination checklist were reliable in identifying infection in DFUs, that wound swabs perform poorly against wound biopsies, and that semi-quantitative analysis of wound swabs may be a useful alternative to quantitative analysis. However, few people with DFUs were included, so it was not possible to tell whether diagnostic performance differs for DFUs relative to wounds of other aetiologies. Twenty-three studies investigated the effectiveness (n = 23) or cost-effectiveness (n = 2) of antimicrobial agents for DFUs. Eight studied intravenous antibiotics, five oral antibiotics, four different topical agents such as dressings, four subcutaneous granulocyte colony stimulating factor (G-CSF), one evaluated oral and topical Ayurvedic preparations and one compared topical sugar versus antibiotics versus standard care. The majority of trials were underpowered and were too dissimilar to be pooled. There was no strong evidence for recommending any particular antimicrobial agent for the prevention of amputation, resolution of infection or ulcer healing. Topical pexiganan cream may be as effective as oral antibiotic treatment with ofloxacin for the resolution of local infection. Ampicillin and sulbactam were less costly than imipenem and cilastatin, a growth factor (G-CSF) was less costly than standard care and cadexomer iodine dressings may be less costly than daily dressings. A decision analytic model was derived for two groups of people, those for whom diagnostic testing would inform treatment--people with ulcers which do not appear infected but whose ulcer is not progressing despite optimal concurrent treatment--and those in whom a first course of antibiotics (prescribed empirically) have failed. There was insufficient information from the systematic reviews or interviews with experts to populate the model with transition probabilities for the sensitivity and specificity of diagnosis of infection in DFUs. Similarly, there was insufficient information on the probabilities of healing, amputation or death in the intervention studies for the two populations of interest. Therefore, we were unable to run the model to inform the most effective diagnostic and treatment strategy. CONCLUSIONS: The available evidence is too weak to be able to draw reliable implications for practice. This means that, in terms of diagnosis, infection in DFUs cannot be reliably identified using clinical assessment. This has implications for determining which patients need formal diagnostic testing for infection, on whether empirical treatment with antibiotics (before the results of diagnostic tests are available) leads to better outcomes, and on identifying the optimal methods of diagnostic testing. With respect to treatment, it is not known whether treatment with systemic or local antibiotics leads to better outcomes or whether any particular agent is more effective. Limited evidence suggests that both G-CSF and cadexomer iodine dressings may be less expensive than 'standard' care, that ampicillin/sulbactam may be less costly than imipenem/cilastatin, and that an unlicensed cream (pexiganan) may be as effective as oral ofloxacin. Further research is needed to ascertain the characteristics of infection in people with DFUs that influence healing and amputation outcomes, to determine whether detecting infection prior to treatment offers any benefit over empirical therapy, and to establish the most effective and cost-effective methods for detecting infection, as well as the relative effectiveness and cost-effectiveness of antimicrobial interventions for DFU infection.

Prevalence of diabetes in care home residents.

OBJECTIVE: To determine the prevalence of known and undetected diabetes diagnosed either by an elevated fasting baseline sample or by a 2-h post-glucose load sample in a group of residents of care homes in an urban-district setting. RESEARCH DESIGN AND METHODS: We completed individual interviews with patients and caregivers in 30 care homes (both residential and nursing homes) in two metropolitan districts of Birmingham, West Midlands, U.K. All care homes were under the supervision of primary care physicians (general practitioners). We carried out 75-g oral glucose tolerance tests (OGTTs) in consenting residents without previous known diabetes. Criteria for diagnosis of diabetes were obtained from the World Health Organization (1998) and the American Diabetes Association (1997). RESULTS: Of 636 residents available for study, 76 residents (12.0%) were known to have diabetes; of the 560 remaining residents, 286 either refused to participate or were deemed too ill or unavailable to undergo testing. Complete data on 274 OGTTs were obtained (median age 83 years, range 45-101). A total of 46 subjects were diagnosed as having diabetes and 94 as having impaired glucose tolerance. Allowing for subjects who refused or were unable to participate, the calculated total prevalence (which includes known and newly detected diabetes) was 26.7% (95% CI 21.9-32.0). The calculated overall prevalence of impaired glucose tolerance was 30.2% (25.2-35.6). CONCLUSIONS: In a group of care home residents not known to have diabetes and able to undergo testing, a substantial proportion have undetected diabetes based on a 2-h postglucose load. These residents warrant further study as they may be at higher cardiovascular risk and require an intervention.

A prospective study of nausea and vomiting during pregnancy.

The symptoms of nausea and vomiting in pregnancy were described by 363 pregnant women who kept daily symptom diaries. All delivered a single live baby. The majority of information collected was prospective, with the median day from last menstrual period to initial interview by the study midwife being day 57. It was found that 80% of women had symptoms, 28% experienced nausea only, while 52% had nausea and vomiting. The mean number of days from last menstrual period to onset and cessation of symptoms was 39 and 84, respectively, and 40% of women's symptoms ended abruptly. Cessation of symptoms occurred at approximately the same day from the last menstrual period whether they had begun early or later, severely or mildly [corrected]. The median total number of hours of nausea per pregnancy in those 292 women experiencing symptoms was 56, with peak symptoms occurring in the ninth week. Eighty five per cent of women experienced days with two episodes of nausea. Fifty three per cent of episodes of vomiting occurred between 06.00 hours and 12.00 hours. The symptom complex can be defined as episodic daytime pregnancy sickness. Among the study population, 206 women were in paid employment. Seventy three of these women (35%) spent a mean of 62 hours away from their paid work because of symptoms of nausea and vomiting, showing the socioeconomic significance of this condition. The detailed information gathered should help in the investigation of the aetiology of nausea and vomiting during pregnancy.

Does the BJGP need more fizz and pop?--A Midland Faculty readership survey.

BACKGROUND: The British Journal of General Practice (BJGP) is the leading primary care journal in the world. By impact factor, it ranks 24th of all medical journals. However, despite major changes in the journal since its inception in 1954, there have been no published readership surveys since a limited report in 1969. AIM: To canvass members of the Midland Faculty and to add to the debate about the future of the BJGP. METHOD: A postal questionnaire was sent to a random sample of 299 members, fellows and associates of the Midland Faculty asking for their views about the BJGP. RESULTS: Two hundred replies were received (a response rate of 67%). The median year of qualification of responders was 1981, and 32 (16%) held academic posts. Ninety-nine (49%) disagreed with the present format of the BJGP, which compared poorly with the British Medical Journal (BMJ) in simple rank order of importance. Readership was equal to that of the BMJ (93% reading it within 28 days of arrival), but fewer people read it within a week of receiving it. The most popular sections were the editorials, original articles and letters; least popular were the book reviews and the pull-out magazine, Connection. All sections were rated excellent to average. Readers wished for an expansion of the BJGP to include clinical reviews, medical politics and humorous pieces. Most responders felt that Connection should remain separate. There was dissatisfaction with the delay between submission and publication of original articles, particularly among the academic general practitioners (GPs). Academics and fundholders did not differ from other readers in their views of the content or style of the BJGP. Half of the responders stated that the BJGP should be self-financing and should be open to more advertising. Responders' free comments largely related to improving the style of articles and expanding the BJGP. CONCLUSION: There is a view that the present BJGP is not relevant to the non-academic GP. This is probably due to style rather than content. Simple comparisons with a weekly multi-disciplinary journal may not be valid. The style could be updated to improve retention of information and to highlight areas of particular relevance. Readers are satisfied with the core content of the BJGP but want it to expand to include humour, clinical reviews and medical politics, for example. There is no evidence that the BJGP is more appealing to the academic GP. This study supports an expanded BJGP with an improved style.

The Multiload CU250 in general practice.

PIP: The experience of partners in general practice with the IUD Multiload CU250 from October 1979-December 1986 is reported as a comparison to results reported from large centers and family planning clinics. 2 physicians fitted the IUDs, and family planning nurses handled counseling and subsequent checkups. The duration of use for each IUD was 2 years, extended to 3 years in 1984. Data on 270 women with their 1st Multiloads are tabulated. There were also 66 women who had a 2nd IUD, and 22 with a 3rd IUD fitted. Parity was usually 1 or 2, but ranged from 1 (8 women) to 5 or more. The nulliparas all had specific histories that made IUD their 1st method choice. The cumulative event rates were pregnancy 3.7 per 100 users at 12 months, expulsion 1.6, removal for bleeding or pain 10.4, other medical reasons 3.1, planned pregnancy 7.4, other personal 2.7, physician's choice 1.6, total continuation rate 69.5%. 5.9% were lost to follow up.^ieng

Attitudes, access and anguish: a qualitative interview study of staff and patients' experiences of diabetic retinopathy screening.

OBJECTIVE: To examine the experiences of patients, health professionals and screeners; their interactions with and understandings of diabetic retinopathy screening (DRS); and how these influence uptake. DESIGN: Purposive, qualitative design using multiperspectival, semistructured interviews and thematic analysis. SETTING: Three UK Screening Programme regions with different service-delivery modes, minority ethnic and deprivation levels across rural, urban and inner-city areas, in general practitioner practices and patients' homes. PARTICIPANTS: 62 including 38 patients (22 regular-screening attenders, 16 non-regular attenders) and 24 professionals (15 primary care professionals and 9 screeners). RESULTS: Antecedents to attendance included knowledge about diabetic retinopathy and screening; antecedents to non-attendance included psychological, pragmatic and social factors. Confusion between photographs taken at routine eye tests and DRS photographs was identified. The differing regional invitation methods and screening locations were discussed, with convenience and transport safety being over-riding considerations for patients. Some patients mentioned significant pain and visual disturbance from mydriasis drops as a deterrent to attendance. CONCLUSIONS: In this, the first study to consider multiperspectival experiential accounts, we identified that proactive coordination of care involving patients, primary care and screening programmes, prior to, during and after screening is required. Multiple factors, prior to, during and after screening, are involved in the attendance and non-attendance for DRS. Further research is needed to establish whether patient self-management educational interventions and the pharmacological reformulation of shorter acting mydriasis drops, may improve uptake of DRS. This might, in turn, reduce preventable vision loss and its associated costs to individuals and their families, and to health and social care providers, reducing current inequalities.
