A cost comparison of an enhanced primary care diabetes service and standard care

BACKGROUND

Type 2 diabetes, which contributes 90% of all cases of diabetes mellitus is now mostly managed in the primary care settings in the UK and other advanced health care systems. The UK National Health Service as a whole could potentially benefit if more patients were managed in primary care settings since primary care-based care is likely to be more cost-effective. We initially compared eight larger general practices (Enhanced practices) in Leicester, UK with neighbouring smaller practices (Core practices) matched for comparable demographic characteristics. Even though this initial study did not find any statistically significant differences in terms of clinical outcomes there was trend in favour of the enhanced practices. In this current study, we conducted a cost comparison of enhanced practice model of diabetes care, to standard care delivered in the core practices.

METHODS

Data and information were combined from a number of sources and a cost comparison evaluation was carried out in WinBUGs. A probabilistic approach was taken, to allow uncertainty to be included around analysis parameters where appropriate. The analysis evaluated a straight-forward cost comparison of enhanced versus standard care.

RESULTS

The cost per person with diabetes per year was £255 (95% CrI 175, 380) in the core practices and £173 (95% CrI 96, 291) in the enhanced practices, resulting in an annual cost saving of -£83 (95% CrI -148, -28) per patient. If the enhanced model of diabetes care were delivered across all the practices in the UK, the cost would be £575,100,000 (95% CrI 320,700,000, 970,700,000), resulting in an annual cost saving of -276,200,000 (95% CrI -495,400,000, -94,480,000).

CONCLUSION

A cost comparison analysis of our larger enhanced primary care based diabetes service confirms significant cost saving, probably driven by economies of scale. These benefits could be multiplied manifold if the service was implemented nationally.

Prevention and management of hyperglycaemic crisis

Hyperglycaemia is a defining feature of diabetes mellitus. It involves an elevated level of glucose in the blood, which develops as a result of the body's inability to produce insulin or process insulin effectively. If left unchecked and untreated, patients with diabetes are at risk of short-term, potentially life-threatening hyperglycaemic crises such as diabetic ketoacidosis or hyperosmolar hyperglycaemic state. Nurses frequently care for patients diagnosed with diabetes in various clinical settings; therefore, it is essential that they have an awareness of the prevention and management of hyperglycaemia and hyperglycaemic crises. This article explains the causes and clinical manifestations of hyperglycaemic crises, and details the management of patients with these conditions, in accordance with national guidelines.

Physical Activity after Cardiac EventS (PACES) - a group education programme with subsequent text-message support designed to increase physical activity in individuals with diagnosed coronary heart disease: study protocol for a randomised controlled trial

BACKGROUND

Coronary heart disease (CHD) represents approximately 13% of deaths worldwide and is the leading cause of death in the UK with considerable associated health care costs. After a CHD event, timely cardiac rehabilitation optimises patient outcomes. However, a high percentage of these services do not meet necessary performance indicators such as course length and follow-up attendance. Uptake of such services is only 50% in UK patients and support provided 12 months after an event is often limited. To delay and prevent further CHD events leading to hospitalisation, supplementary self-management strategies such as group education, are necessary.

METHODS

This is a single-centre, randomised controlled trial (RCT) recruiting participants (n = 290) aged ≥18 years who are 12 to 48 months post diagnosis of a CHD-related cardiac event (myocardial infarction, angina and any other acute coronary syndrome). The study aims to implement a structured education programme, with text-message support over 12 months, and identify whether delivery of the programme, to individuals who have a history of a cardiac event, would be an effective and cost-effective strategy for increasing walking. The primary outcome, objectively measured average daily physical activity, specifically step count through walking activity, is assessed using the wrist-worn GENEActiv accelerometer at baseline, 6 and 12 months. Secondary outcomes at 12 months include cardiovascular risk factors such as smoking status, blood pressure, lipid profile, glycated haemoglobin (HbA1c), obesity, self-efficacy, quality of life, physical activity and physical function. Participants are randomised to either the control group receiving standard care and a physical activity information leaflet, or the intervention group whose partcipants receive the leaflet and are invited to attend two group-based structured education sessions. These encourage participants to adopt and maintain healthy behaviours and self-manage their lifestyle. They are delivered approximately 2 weeks apart by trained facilitators and reinforced via subsequent text-message support.

DISCUSSION

To our knowledge, this is the first trial designed to assess the effectiveness of a group education programme 12 to 48 months after a CHD event diagnosis. If successful, the PACES programme could be translated into effective post-operative cardiac care and complement the current post-operative services available.
