(1) Background: A major problem affecting geriatric patients is pain. In addition to pain, a significant problem of old age is dementia and depression, which can hinder the diagnosis and treatment of pain. The aim of this study was to analyse the prevalence of pain in patients treated in a geriatric outpatient clinic and the treatment used. (2) Methods: The analysis was based on the records of 937 patients who visited the Geriatric Outpatient Clinic in Dobre Miasto between 2015 and 2020. Based on records containing data dating back to their first visit to the hospital, patients’ experiences of pain, the presence of depressive symptoms and dementia, and the pharmacological treatment used for pain (analgesics and coanalgesics) were analysed. (3) Results: Pain complaints were reported by 311 patients (33.2% of the study group), 76% of the complaints were from females. The mean age of the patients was 78 years (SD = 8.45). At least one analgesic drug was taken by 107 patients (34.4%). The most commonly used analgesics were opioids (63 patients, 58.87%), especially tramadol. Of the potential coanalgesics, the largest number of patients used an antidepressant. (4) Conclusions: Despite the widespread prevalence of pain among the elderly, only about one-third of them were taking pain medication, mainly in the form of weak opioids. Patients with symptoms of dementia were found to report pain less frequently.

Introduction: Vitamin B12 deficiency is becoming a major problem among geriatric population worldwide. It may contribute to higher prevalence of cognitive impairment and depression, and may occur as a side effect of commonly prescribed anti-diabetic and anti-acid treatments. However, the scale of this phenomenon in Poland remains unknown. Aim: We investigated the scale of vitamin B12 deficiency across population of geriatric patients over 70 years old. Additionally, we examined the association between vitamin B12 deficiency, cognitive impairment or depression prevalence, and metformin or proton pump inhibitors intake. Material and methods: Based on the measured vitamin B12 serum level, we divided patients into 3 groups: (1) normal (≥300 pg/mL); (2) borderline (191–300 pg/mL), and (3) low (≤191 pg/mL). The assessment of cognitive impairment or depression was performed by using 5 distinct tests (mini-mental state examination, abbreviated mental test score, clock drawing test, and 4-item or 15-item geriatric depression scale). For statistical analysis, we used χ2 and ANOVA tests. Results and discussion: We showed no differences in the frequency of cognitive impairment, depression, and vitamin among characterized groups. Importantly, we found that metformin intake was associated with vitamin B12 deficiency (P = 0.009), contrary to proton pump inhibitor (P = 0.53) and combined these drugs (P = 0.24). Conclusions: We showed a relatively high prevalence of vitamin B12 deficiency across a population of geriatric patients. A preventive vitamin B12 supplementation should be considered when treating, especially geriatric diabetic patients. Due to conflicting results of retrospective studies, prospective clinical trial should be undertaken to describe the association between vitamin B12 deficiency and prevalence of cognitive impairment or depression.
