Aim: To examine the hypothesis that Collagen Peptide (CP) is effective in the treatment of Pressure Injuries (PI) in older adult inpatients. Methods: This study was a retrospective chart review conducted at a single institution. All consecutive patients who developed PI before or after admission to a single institution between January 2013 and September 2015 were enrolled. Data collected were: 1) characteristics; 2) blood test, CRP, and serum Alb during the period of PI treatment (PPT); 3) PI, evaluated by the DESIGN-R scoring system; 4) nutrition, body weight, BMI at baseline, and energy and protein intake during PPT; and 5) outcomes, the change in DESIGN-R score during PPT (ΔD), ΔD/PPT. Subjects were divided into two groups: with or without CP supplement. All collected data were compared for PI patients in Method 1: PPT ≤ 28 days vs. >28 days and Method 2: PPT ≤ 28 days treated with CP vs. non-CP. Results: Among 2,245 included patients, the prevalence of PI and incidence of hospital-acquired PI were 2.93% and 1.69%, respectively. Result 1: PI patients with PPT ≤ vs. >28 days had the following characteristics: ≥ 89 years old, lower Alb, and a less severe PI expressed as a DESIGN-R score <10. The outcomes, expressed as PPT/ΔD and ΔD/PPT, were also significantly better. Result 2: the CPgroup had a more severe PI and, paradoxically, a significantly lower Alb and Hb at baseline. Conclusion: From our results, two conclusions were drawn: (1) PI inpatients who healed within 28 days were ≥ 89 years old, had a lower Alb, and had better outcomes, expressed by a significantly shorter PPT/ΔD. (2) PI inpatients treated with CP, who had a more severe PI and, paradoxically, a significantly lower Alb and Hb at baseline, healed within 28 days. In conclusion, CP could be a strategic agent for PI treatment for inpatients ≥ 89 years old, a lower Alb and Hb, and a DESIGN-R score <10 at baseline.
