Estimating and examining the costs of inpatient diabetes care in an Irish Public Hospital

AIM

To estimate and examine hospitalisation costs of Type 1 and Type 2 diabetes in an Irish public hospital.

METHODS

A retrospective audit of hospital inpatient admissions over a 5-year period was undertaken, and a wide range of admission-related data were collected for a sample of 7,548 admissions. Hospitalisations were costed using the diagnosis-related group methodology. A series of descriptive, univariate and multivariate regression analyses were undertaken.

RESULTS

The mean hospitalisation cost for Type 1 diabetes was €4,027 and for Type 2 diabetes was €5,026 per admission. Sex, admission type and length of stay were significantly associated with hospitalisation costs for admissions with a primary diagnosis of Type 1 diabetes. Age, admission type, diagnosis status, complications status, discharge destination, length of stay and year were significantly associated with hospitalisation costs for admissions with a primary diagnosis of Type 2 diabetes. Length of stay was associated with higher mean costs, with each additional day increasing Type 1 diabetes costs by €260 (p = 0.001) and Type 2 diabetes by €216 (p < 0.001). Unscheduled admissions were associated with significantly lower costs than elective admissions; €1,578 (p = 0.035) lower for Type 1 diabetes and €2,108 (p < 0.001) lower for Type 2 diabetes.

CONCLUSIONS

This study presents estimates of the costs of diabetes care in the Irish public hospital system and identifies the factors which influence costs for Type 1 and Type 2 diabetes. These findings may be of interest to patients, the public, researchers and those with influence over diabetes policy and practice in Ireland and internationally.

Health professionals’ views of the first national GP payment scheme for structured type 2 diabetes care in Ireland: a qualitative study

Background: Payment schemes are widely used to improve chronic disease management in general practice. Although stakeholder views of such schemes could provide valuable learning regarding aspects that work and those which are more difficult to implement, there is a paucity of such data. We explored health professionals’ views of the implementation of the first national general practice payment scheme for type 2 diabetes (T2DM) care in Ireland, the ‘cycle of care’. Methods: Qualitative data were drawn from a multiple case study evaluating the implementation of a National Clinical Programme for Diabetes, collected from April 2016 to June 2017. Interview and focus group transcripts from participants involved in providing diabetes management in general practice and who referenced the cycle of care were eligible for inclusion in the current analysis. Data were analysed using reflective thematic analysis. Results: We analysed data from 28 participants comprising general practitioners (GPs) (n=8), practice nurses (n=9) and diabetes nurse specialists (DNS) (n=11). Participants perceived the cycle of care as “not adequate, but…a good start” to improve T2DM care in general practice in Ireland. Perceived benefits were greater financial viability for T2DM management in general practice, fostering a more proactive approach to T2DM care, delivery of T2DM care closer to patients’ homes, and increased use of other community diabetes services e.g., DNS and podiatry. Participants identified the limited resource for practice nurse time, inflexibility to provide care based on patient need and issues with data submission as drawbacks of the cycle of care. Conclusions: The cycle of care was viewed as a positive first step to increase and improve T2DM care delivered in general practice in Ireland. The implementation issues identified in this study should be considered in the design of future payment schemes targeting chronic disease management in general practice.

A comparison, for older people with diabetes, of health and health care utilisation in two different health systems on the island of Ireland

Background

There are social and economic differences between Northern Ireland (NI) and the Republic of Ireland (ROI). There are also differences in the health care systems in the two jurisdictions. The aims of this study are to compare health (prevalence of diabetes and related complications) and health care utilisation (general practitioner, outpatient or accident and emergency utilisation) among older people with diabetes in the NI and ROI.

Methods

Large scale comparable surveys of people over 50 years of age in Northern Ireland (NICOLA, wave 1) and the Republic of Ireland (TILDA, wave 1) are used to compare people with diabetes (type I and type II) in the two jurisdictions. The combined data set comprises 1536 people with diabetes. A coarsened exact matching approach is used to compare health care utilisation among people with diabetes in NI and ROI with equivalent demographic, lifestyle and illness characteristics (age, gender, education, smoking status and self-related health, number of other chronic diseases and number of diabetic complications).

Results

The overall prevalence of diabetes in the 50 to 84 years old age group is 3.4 percentage points higher in NI (11.1% in NI, 7.7% ROI, p-value < 0.01). The diabetic population in NI appear sicker – with more diabetic complications and more chronic illnesses. Comparing people with diabetes in the two jurisdictions with similar levels of illness we find that there are no statistically significant differences in GP, outpatient or A&E utilisation.

Conclusion

Despite the proximity of NI and ROI there are substantial differences in the prevalence of diabetes and its related complications. Despite differences in the health services in the two jurisdictions the differences in health care utilisation for an equivalent cohort are small.
