Case report: Skin protective barrier cream interference in benzethonium chloride method for urine protein measurement in a 6-month-old girl.

This case report describes the positive interference of the commonly used skin protective barrier cream used together with urine collection bags on the benzethonium chloride method for urine protein measurements in a 6-month-old female baby, leading to falsely elevated results. The interference was identified by both artificially mixing urine samples with this cream and comparing the results obtained using the benzethonium chloride method with those obtained using the pyrogallol red method.

The effectiveness of an automated algorithm as a tool for investigating the cause of anaemia in undiagnosed patients from general practitioners.

BACKGROUND: The Dutch guideline algorithm for the analysis of anaemia in patients of general practitioners (GPs) was programmed in a Clinical Decision Support system (CDS-anaemia) to support the process of diagnosing the cause of anaemia in the laboratory. This study investigates the diagnostic yield of the automated anaemia algorithm compared to that of the manual work up by the GP. METHODS: This retrospective population-based study consisted of 2697 people ≥18 years. Anaemia was defined according to the Dutch College of General Practitioners (DCGP) guideline. Causes of anaemia were based on the DCGP guidelines with the corresponding blood tests. The number of blood tests and causes of anaemia were measured in two separate periods in both the (CDS-anaemia) pilot group and a control group in which routine care was provided. RESULTS: Patients from GPs supported by CDS-anaemia had higher chances of having more anaemia-related blood tests being performed. This resulted in finding significantly more causes of anaemia in the pilot group compared to the control group with respect to iron deficiency (resp. 31.3% vs 14.5%), possible iron deficiency (resp. 11.4% vs 2.8%), iron deficiency in acute phase (2.6% vs 0.5%), chronic disease/infection/inflammation (23.5% vs 1.9%), vitamin B12 deficiency (4.5% vs 1.9%), possible vitamin B12 deficiency (16.8% vs 8.7%), folate deficiency (3.3% vs 0.9%) and possible bone marrow disorder (3.8% vs 0.0%); p < 0.05. CONCLUSIONS: This study suggests that an automated-algorithm support can effectively aid in the diagnostic work-up of anaemia in primary care to find more causes of anaemia.

Goal attainment scaling with older people in general practice: A feasibility study.

Background: The impact of health problems on daily life and consequent treatment goals differ from person to person, particularly for older people with multiple health problems. Personalized care in general practice can help address these health problems, but evaluation of its effects remains difficult. In rehabilitation, a common approach to the evaluation of personalized care is Goal Attainment Scaling. This feasibility study assesses whether goal attainment scaling can also be applied to the evaluation of personal care for community-dwelling older people in general practice. Methods: General practices were invited to participate in this longitudinal, observational feasibility study. Practice nurses and general practitioners received training in care plans and goal attainment scaling. They were each asked to create care plans and goal attainment scales for patients (aged ≥75 years) and to carry out evaluations at three and six months. Professionals and patients both completed a short questionnaire to evaluate their experiences regarding the (dis)advantages of goal attainment scaling. Results: Professionals (n=10) and patients (n=23) were able to set goals and scales (n=57) for problems across five health domains (somatic, functional, social, psychological and communicative), but experienced difficulties formulating goals and corresponding goal attainment scaling levels. Reported benefits of goal attainment scaling were 1) important problems were addressed, 2) patients were involved and motivated to attain goals, and 3) evaluation was straightforward once a scale was created. Disadvantages were 1) difficult for older people, 2) time-consuming and complex for clinical practice. Conclusions: Goal attainment scaling shows potential benefit for clinical practice and general practice research in terms of the setting and evaluation of goals for community-dwelling older persons. Further research is needed to develop more standardized and less time-consuming goal attainment scaling methods.

The effect of vitamin B12 and folic acid supplementation on routine haematological parameters in older people: an individual participant data meta-analysis.

BACKGROUND/OBJECTIVES: Low vitamin B12 and folate levels in community-dwelling older people are usually corrected with supplements. However, the effect of this supplementation on haematological parameters in older persons is not known. Therefore, we executed a systematic review and individual participant data meta-analysis of randomised placebo-controlled trials (RCTs). SUBJECTS/METHODS: We performed a systematic search in PubMed, EMBASE, Web of Science, Cochrane and CENTRAL for RCTs published between January 1950 and April 2016, where community-dwelling elderly (60+ years) who were treated with vitamin B12 or folic acid or placebo. The presence of anaemia was not required. We analysed the data on haematological parameters with a two-stage IPD meta-analysis. RESULTS: We found 494 full papers covering 14 studies. Data were shared by the authors of four RCTs comparing vitamin B12 with placebo (n = 343) and of three RCTs comparing folic acid with placebo (n = 929). We found no effect of vitamin B12 supplementation on haemoglobin (change 0.00 g/dL, 95% CI: -0.19;0.18), and no effect of folic acid supplementation (change -0.09 g/dL, 95% CI: -0.19;0.01). The effects of supplementation on other haematological parameters were similar. The effects did not differ by sex or by age group. Also, no effect was found in a subgroup of patients with anaemia and a subgroup of patients who were treated >4 weeks. CONCLUSIONS: Evidence on the effects of supplementation of low concentrations of vitamin B12 and folate on haematological parameters in community-dwelling older people is inconclusive. Further research is needed before firm recommendations can be made concerning the supplementation of vitamin B12 and folate.
