Understanding why people with type 1 diabetes do not attend for specialist advice: a qualitative analysis of the views of people with insulin-dependent diabetes who do not attend diabetes clinic.

Attendance at diabetes clinic is associated with improved medical outcome, however, significant numbers of people with type 1 diabetes choose not to attend. In order to understand the reasons underlying this decision, qualitative interviews were carried out with 12 long-term non-attenders. Three distinct groups emerged differing in terms of their cognitive and emotional responses to diabetes and their coping strategies: (1) the 'High fear' group; (2) the 'Patient as expert' group; and (3) the 'Low motivation' group. These differences should be recognized and suitable approaches developed to ensure that all people with diabetes are able to accept appropriate specialist support.

Using the IPQ and PMDI to predict regular diabetes care-seeking among patients with Type 1 diabetes.

OBJECTIVES: The objectives were, first, to identify factors associated with regular diabetes care-seeking and, second, to compare the performance of the Illness Perception Questionnaire (IPQ) and a modified version of the Personal Models of Diabetes Interview (PMDI) in predicting care-seeking. METHOD: This was a cross-sectional study involving 42 patients who had not attended hospital diabetes clinic for a period of 18 months or more and 42 matched controls receiving specialist care. Differences in illness representations between clinic attenders and non-attenders were examined. Due to the variability in care-seeking between non-attenders (ranging from no contact with health professionals to regular general practitioners care), participants were then reclassified for further analyses into those receiving regular care from either hospital diabetes clinic or general practice (n = 52) and those receiving no regular care (n = 32). RESULTS: Patients not seeking regular care held more negative views of the control, course and consequences of diabetes than those who received regular care. Regression analyses showed that the most important construct was treatment effectiveness. Treatment effectiveness (PMDI) and control (IPQ) dimensions were associated with clinic attendance. PMDI constructs of treatment effectiveness, threat and worries were associated with regular care-seeking. CONCLUSIONS: IPQ and PMDI results were generally consistent. In order to understand diabetes care-seeking behaviour it is important to measure beliefs about the benefits of treatment recommendations in addition to those of the disease itself. Emotional and cognitive responses to diabetes should be assessed.

Pressure ulcer risk assessment: application of logistic analysis.

AIM: The aim of this study was to investigate the relative importance of key factors affecting the likelihood of hospital acquired pressure ulcers, thus offering the groundwork for the development of an empirically-based risk assessment scale. It also evaluated the predictive performance of the underlying empirical model and compared its classification ability with the empirically observed ability of the Waterlow risk assessment scale. BACKGROUND: Pressure ulcers impose a significant burden on patients and carers and demand substantial resources from the health care system. There is, however, a lack of systematic empirical research on which to base the development of risk assessment measurement tools. METHODS: Multivariate statistical methods were applied to data derived from the records of a cross-sectional sample of around 500 randomly selected inpatient episodes drawn from the population of admissions to a single unit in a large acute hospital during a 2-year period (October 1996 to September 1998). Double-checking of a randomly selected 25% sample of the original records and careful screening out of records with incomplete information or inconsistent values was carried out to ensure a high quality sample. Logit analysis was used to investigate the relative contribution of risk factors, such as continence, skin condition, mobility and inter-hospital transfer to the risk of hospital-acquired pressure ulcer occurrence, whilst cross-validation techniques were employed to check the predictive performance of the model. RESULTS: The results suggest that a simplified version of the Waterlow risk assessment tool has satisfactory predictive ability and the potential for further development. CONCLUSIONS: Two main conclusions emerged from this study. First, it is both feasible and worthwhile to pursue improvement in the development of risk assessment tools using statistical methods. Second, locally-determined risk factors will need to be incorporated into the construction of future risk assessment scales.

Improving the accuracy of pressure ulcer risk calculators: some preliminary evidence.

This study presents data from a prospective cohort study of 213 in-patient admissions of people over 65. Logit analysis was used to investigate the relative contribution of a range of risk factors to the risk of pressure ulcer occurrence, as a basis for development of improved risk assessment tools. It was found that for this population, a model containing the Waterlow risk factors appetite, continence, skin condition and age, plus diagnosis, performed better than one based on the complete set of Waterlow factors. Gender was not significant. A diagnosis of cancer was positively associated with pressure ulcer occurrence but presence of Parkinson's disease had the opposite effect.
