Organizational changes in diabetic foot care practices for patients at low and moderate risk after implementing a comprehensive foot care program in Alberta, Canada.

BACKGROUND: Neuropathy and vasculopathy can lead to costly and debilitating complications in people with diabetes. The purpose of this study was to evaluate, at an organizational level, uptake of practices included in a diabetic foot care clinical pathway and associated resources. This research focused on patients at low and moderate risk in Alberta, Canada between 2014 to 2019. METHODS: Serial surveys (2014, 2019) of practices related to screening and care of the feet of people with diabetes. Surveys were administered using a combination of targeted and snowball sampling in order to assess the impact of the clinical pathway first implemented in 2015. The pathway focused on screening, assessment and referral of patients from primary care. High-risk foot teams (HRFT) were established at six sites to provide increased access to specialty care. Comparative statistics were performed to assess differences in footcare practices between 2014 and 2019 using two-tailed Fisher's exact test or Chi-square test. RESULTS: Respondents (n = 104, 2014 and n = 75, 2019) included personnel from primary health care, home care and long-term care, acute and emergency care, specialty clinics, diabetes-specific programs and private contractors. The proportion of primary care and home care/long-term care (HC/LTC) sites providing screening increased significantly (p < 0.05). A significant increase in the proportion of sites providing assessment for patients designated as moderate risk also increased from 35% (34 out of 96 sites) to 55% (36 out of 65 sites) (p < 0.05), particularly with respect to vascular assessment, and the proportion of sites reporting appropriate follow-up intervals according to the pathway recommendation was also improved. CONCLUSION: Provision of a clinical pathway for diabetic foot care along with education and resources led to increased screening in primary care and HC/LTC settings in Alberta, Canada. HRFT provided primary healthcare providers with an important option for referral and also provided increased expertise for procedures such as vascular assessment for patients with moderate risk of ulceration. This comprehensive model has the potential to reduce progression of foot problems and overall health services utilization. Further analyses of outcomes such as incident lower limb amputation and long-term cost-effectiveness of pathway implementation are underway.

Return on investment of the diabetes foot care clinical pathway implementation in Alberta, Canada.

AIMS: Based on best practices, the diabetes foot care clinical pathway (DFCCP) has been developed and implemented in several clinics in Alberta, Canada. We performed a return on investment (ROI) analysis of this implementation. METHODS: We used a cohort design comparing both cost and return (in terms of reduced health services utilization, HSU) between diabetes patients who were exposed and who were unexposed, to the intervention. We used a difference-in-difference approach and a propensity-score-matching technique to minimize biases due to differences in demographic and clinical characteristics between two cohorts. We used a 1-year time-horizon and converted all costs/savings to 2019 Canadian dollars (1 CA$ ~= 0.75 US$). RESULTS: The intervention helped avoid $3500 in costs of HSU per patient-year. Subtracting the intervention cost of $500, the net benefit of intervention was $3000 (ranged $2400-$3700) per patient-year. The ROI ratio was estimated at 7.4 (ranged 6.1 to 8.8) meaning that every invested $1 returned $7.4 (ranged $6.1-$8.8) for the health system. The probability of intervention being cost-saving ranged from 99.5-100%. CONCLUSIONS: The implementation of DFCCP in Alberta is cost-saving. A continuation of the pathway implementation at studied clinics and a spread to other clinics are recommended.
