ICP-MS As a Contributing Tool to Nontarget Screening (NTS) Analysis for Environmental Monitoring.

Due to the increasing number of chemicals released into the environment, nontarget screening (NTS) analysis is a necessary tool for providing comprehensive chemical analysis of environmental pollutants. However, NTS workflows encounter challenges in detecting both known and unknown pollutants with common chromatography high-resolution mass spectrometry (HRMS) methods. Identification of unknowns is hindered by limited elemental composition information, and quantification without identical reference standards is prone to errors. To address these issues, we propose the use of inductively coupled plasma mass spectrometry (ICP-MS) as an element-specific detector. ICP-MS can enhance the confidence of compound identification and improve quantification in NTS due to its element-specific response and unambiguous chemical composition information. Additionally, mass balance calculations for individual elements (F, Br, Cl, etc.) enable assessment of total recovery of those elements and evaluation of NTS workflows. Despite its benefits, implementing ICP-MS in NTS analysis and environmental regulation requires overcoming certain shortcomings and challenges, which are discussed herein.

An ostomy baseplate with a skin-protection technology reduces peristomal skin complications: a randomized controlled trial (the ATTRACT study).

BACKGROUND: Peristomal skin complications (PSCs) are the predominant complication for people living with a stoma, negatively affecting their health-related quality of life (HRQoL). PSCs may also have an impact on healthcare costs for society with more visits to healthcare professionals and increased consumption of products and treatment strategies, which amplifies the need for new strategies to reduce or prevent PSCs. OBJECTIVES: To evaluate the performance of an ostomy baseplate with a skin-protection technology. The target group comprised people living with a stoma with liquid faecal effluent, who struggled with PSCs. METHODS: A randomized, controlled, open-labelled, cross-over trial was conducted from September 2021 to February 2022 in five different countries. Each participant tested the investigational product against a comparator product (SenSura® Mio). The Ostomy Skin Tool 2.0 was used to evaluate the peristomal skin and HRQoL was measured using the Dermatology Life Quality Index (DLQI) questionnaire. Data were analysed in mixed repeated-measures models. RESULTS: A total of 79 adult participants (mean age 54.5 years, female 45.6%) were included in the intention-to-treat (ITT) population. A significant reduction in PSCs (P = 0.015) and HRQoL (P = 0.035) was found for the investigational product when compared with the comparator product. Also, significantly more study participants preferred the investigational product when compared with the comparator product (P = 0.017). CONCLUSIONS: The investigational product, an ostomy baseplate with a skin-protective technology, reduced PSCs and improved the HRQoL of people living with a stoma with liquid faecal effluent. Consequently, the investigational product was the preferred ostomy appliance of the participants. Thus, the product investigated in this study may be a new solution to be included in everyday clinical practice to overcome leakage-induced PSCs for people living with a stoma.

Home-based training technology for persons with dementia: a qualitative study of barriers and facilitators for mobility-based training at home.

BACKGROUND: Physical training is increasingly used in rehabilitation for older people with dementia and several studies have documented positive results. Currently, welfare nations promote motion-based technology (MBT) at home to replace group training in various rehabilitation interventions. Research on the use of MBT by people with dementia is sparse. Therefore, this study explores how people with mild dementia and their relatives experience home-based MBT training in an intervention facilitated by a Danish municipality. METHODS: The study is part of a feasibility study and builds on participant observation and interviews with people with dementia (n = 4), their relatives (n = 4), and health care workers (n = 3) engaged in the project. RESULTS: Participants compared MBT training to group training and found that MBT was not a satisfactory replacement for group training. Some participants used and enjoyed MBT daily while others were challenged by the technology, the placement of the device, or motivation to independently complete the training program. CONCLUSION: MBT is possibly best considered as a supplement to group training, suitable for individuals able to use it in daily life.

Feedback-informed treatment: A systematic review and meta-analysis of the partners for change outcome management system.

The Partners for Change Outcome System (PCOMS) is a feedback system that has been developed as part of psychotherapeutic treatment. The aim of this systematic review was to evaluate the effect of the PCOMS. We searched the literature and included studies that used a randomized controlled trial (RCT) design. We calculated a combined effect size across studies for outcomes related to the number of sessions attended. We also calculated a combined effect size for outcomes related to the participants' well-being. However, in the analysis of the effect on well-being, we excluded studies that included only the Outcome Rating Scale as a measure of effect because this scale is part of the PCOMS. In the calculation of the combined effect size, we used random effect models with inverse weighted variance. In the systematic literature search we identified 14 RCT studies that evaluated the effect of the PCOMS. Based on 12 studies, we found a rather small effect size for the number of sessions attended favoring the PCOMS intervention (Hedges's g = 0.13; 95% confidence interval [CI: 0.001, 0.26]). The effect size corresponded to a difference of less than 1 session. Six studies included a well-being scale that was independent of the PCOMS intervention as the outcome. The effect size for the 6 studies was insignificant (Hedges's g = 0.03; 95% Cl [-0.18, 0.23]). We found no evidence that the PCOMS feedback system has an effect on the number of sessions attended by clients or that the PCOMS improves the well-being of clients.

Parent Management Training Oregon Model and Family-Based Services as Usual for Behavioral Problems in Youth: A National Randomized Controlled Trial in Denmark.

This randomized control trial used intent-to-treat analyses to compare parent management training-Oregon model (PMTO) (N = 64) to family-based services as usual (SAU) (N = 62) in 3.5-13-year-old children and their families in Denmark. Outcomes were parent report of child internalizing and externalizing problems, parenting efficacy, parenting stress, parent sense of coherence, parent-report of life satisfaction, and parental depressive symptoms. Outcomes were measured at pretreatment, post-treatment, and 18-20 months post-treatment. Results demonstrated that both PMTO and family-based SAU resulted in significant improvements in child externalizing and internalizing problems, parenting efficacy, as well as parent-reported stress and depressive symptoms, life satisfaction, and aspects of sense of cohesion. Effect sizes at post-treatment and follow-up were in the small to moderate range, consistent with prior PMTO evaluations. However, there were no significant differences between PMTO and family-based SAU. Further research on the process and content of family-based SAU is needed to determine how this approach overlaps with and is distinct from PMTO.

Outpatient total hip or knee arthroplasty in ambulatory surgery center versus arthroplasty ward: a randomized controlled trial.

Background and purpose - Discharge on the day of surgery (DOS) in selected patients operated with total hip arthroplasty (THA) or total knee arthroplasty (TKA) has been shown to be feasible, but different factors may determine whether patients are discharged on the DOS or not and setting may be one of them. We investigated the importance of the setting in which the short stay following outpatient THA or TKA takes place: was there a difference between the proportion of patients being discharged on the DOS from an ambulatory surgery center (ASC) compared with patients staying on an arthroplasty ward?Patients and methods - 50 patients (30 TKA, 20 THA) were included in the study and postoperatively randomized to either staying in the ASC or the arthroplasty ward until discharge. All patients were operated under general anesthesia by the same experienced surgeon (HH) and were discharged upon fulfillment of standardized discharge criteria.Results - 24/25 of the patients who stayed in the ASC compared with 20/25 of the patients on the arthroplasty ward were discharged on the DOS following fulfillment of discharge criteria (p = 0.08). All THA patients were discharged on the DOS and significantly more TKA patients were discharged from the ASC (15/16) vs. from the ward (9/14) (p = 0.04).Interpretation - Despite fixed discharge criteria, the logistical setting may play a role for achieving discharge on DOS and the ASC may facilitate achieving discharge criteria earlier especially in TKA.

Men with cancer and their experiences of marital relationships: a struggle for control and balance.

Presently, there is a general understanding that health, illness and rehabilitation should be studied in a relational context, and that people's experiences, perceptions and practices in relation to health and recovery are formed relationally and contextually. The aim of this paper is to consider and discuss how men experienced their marital relationships, after being diagnosed with cancer. The empirical material is based on the authors' ethnographic fieldworks, including participant observation and interviews with men who have or have had cancer. The analysis is informed by the anthropologist Michael Jackson's notion of intersubjectivity and his argument that intersubjectivity continually and dialectically moves between the complementary poles of compassion and conflict. We demonstrate how the men appreciated their partners' support and care, but also that the cancer disease and the treatment could cause marital friction and tension. Due to their new life circumstances and subject positions, the men continuously shifted between the poles of compassion and conflict, struggling for balance and control, including negotiations of how to perform their masculinity.

Feeling lucky: hierarchies of suffering and stories of endometrial cancer in a Danish context.

Illness stories are a prime analytical way of understanding patient perspectives on cancer. Nevertheless, limited studies have focused on stories of endometrial cancer. An ethnographic study including participant observation and interviews among 18 Danish women with endometrial cancer was conducted to examine prevalent stories and the ways the women responded to them. In this article, the analysis focuses on two exemplary cases, which present a line of issues related to the kinds of experiences that suffering includes. Findings illustrate that feelings of luck were central to the experience of being diagnosed, treated and cured, which was related to the way health professionals framed endometrial cancer as favourable through notions of curable/incurable, trivial and gentle/invasive and brutal, and aggressive/non-aggressive. Drawing upon the concept of a 'hierarchy of suffering', we exemplify how women tended to scale own experiences of suffering against others', leading some to believe they were not in a legitimate position to draw attention to themselves nor seek help and support, despite adverse physical, psychosocial effects. Thus, feelings of being lucky were intertwined with a sense of ambivalence. We conclude by discussing how suffering arises within a moral context, suggesting that the ways we speak of cancer may make some experiences unspeakable. This calls for increased clinical attention to more diverse narratives of cancer.

Negotiated mobilisation: An ethnographic exploration of nurse-patient interactions in an intensive care unit.

AIMS AND OBJECTIVES: To explore nurse-patient interactions in relation to the mobilisation of nonsedated and awake, mechanically ventilated patients in the intensive care unit. BACKGROUND: Lighter sedation has enabled the early mobilisation of mechanically ventilated patients, but little is known about the nurses' role and interaction with critically ill patients in relation to mobilisation. DESIGN AND METHODS: The study had a qualitative design using an ethnographic approach within the methodology of interpretive description. Data were generated in two intensive care units in Denmark, where a strategy of no sedation was applied. Participant observation was conducted during 58 nurse-patient interactions in relation to mobilisation between nurses (n = 44) and mechanically ventilated patients (n = 25). We conducted interviews with nurses (n = 16) and patients (n = 13) who had been mechanically ventilated for at least 3 days. The data were analysed using inductive, thematic analysis. The report of the study adhered to the COREQ checklist. FINDING: We identified three themes: "Diverging perspectives on mobilisation" showed that nurses had a long-term and treatment-oriented perspective on mobilisation, while patients had a short-term perspective and regarded mobilisation as overwhelming in their present situation. "Negotiation about mobilisation" demonstrated how patients actively negotiated the terms of mobilisation with the nurse. "Inducing hope through mobilisation" captured how nurses encouraged mobilisation by integrating aspects of the patient's daily life as a way to instil hope for the future. CONCLUSIONS: Exploring the nurse-patient interactions illustrated that mobilisation is more than physical activity. Mobilisation is accomplished through nurse-patient collaborations as a negotiated, complex and meaningful achievement, which is driven by the logic of care, leading to hope for the future. RELEVANCE TO CLINICAL PRACTICE: The study demonstrated the important role of nurses in achieving mobilisation in collaboration and through negotiation with mechanically ventilated patients in the intensive care unit.

"But this is a good cancer:" Patient perceptions of endometrial cancer in Denmark.

AIMS AND OBJECTIVES: To explore endometrial cancer patients' perceptions of the disease and the influence of favourable prognoses on their experiences. BACKGROUND: Endometrial cancer is associated with favourable prognoses, which may imply that patients experience distress to a lesser extent than other cancer patients with less positive treatment outcomes. However, most people with cancer report reduced quality of life and, despite endometrial cancer being prevalent worldwide, experiences of the disease have been little explored. DESIGN: Ethnographic fieldwork with participant observations and interviews. METHODS: Observations during clinical consultations at two Danish hospitals and interviews with women with endometrial cancer (n = 18) over a period of 6 months. The article adheres to the COREQ guidelines for reporting qualitative research. RESULTS: We identify how patients consider cancer in general very likely to be fatal, while clinicians in contrast characterise endometrial cancer specifically as "good" because of favourable prognoses. We employ the concept of bricolage to illustrate how bits and pieces of biomedical knowledge and statistical evidence become intertwined with patients' past experiences and subjective ways of knowing, suggesting that patients' perceptions of endometrial cancer as a disease are somewhat dynamic. CONCLUSIONS: Public stories and everyday life experiences of cancer provide a central framework for illness perceptions. As a result, patients retain the idea of a close connection between cancer and death, while also adopting the notion of endometrial cancer as "good". This influenced how women responded to treatment and care. Framing endometrial cancer as "good" is not always helpful, as the impact of a cancer diagnosis per se is rarely favourable. RELEVANCE TO CLINICAL PRACTICE: In providing women with endometrial cancer with optimal support through diagnosis and treatment, clinicians should attend to the complexity of patients' illness understandings and be aware that assuring patients of a good prognosis not always has the expected impact.

Teaching Cancer Patients the Value of Correct Positioning During Radiotherapy Using Visual Aids and Practical Exercises.

The aim of this study was to investigate if teaching patients about positioning before radiotherapy treatment would (a) reduce the residual rotational set-up errors, (b) reduce the number of repositionings and (c) improve patients' sense of control by increasing self-efficacy and reducing distress. Patients were randomized to either standard care (control group) or standard care and a teaching session combining visual aids and practical exercises (intervention group). Daily images from the treatment sessions were evaluated off-line. Both groups filled in a questionnaire before and at the end of the treatment course on various aspects of cooperation with the staff regarding positioning. Comparisons of residual rotational set-up errors showed an improvement in the intervention group compared to the control group. No significant differences were found in number of repositionings, self-efficacy or distress. Results show that it is possible to teach patients about positioning and thereby improve precision in positioning. Teaching patients about positioning did not seem to affect self-efficacy or distress scores at baseline and at the end of the treatment course.

General practitioners' experience of using a questionnaire when assessing cancer patients' needs: a qualitative study.

BACKGROUND: International guidelines recommend health care professionals to use supportive tools like questionnaires when assessing cancer patients' needs. Little is known about GPs' perspectives and experience in this regard. OBJECTIVE: To examine how GPs experience to involve a short questionnaire, completed by patients' prior to a consultation, when addressing the patients' problems and needs. The aim is to contribute to the knowledge concerning the use of questionnaires as part of clinical cancer care in general practice. METHODS: Semi-structured individual interviews with 11 GPs in the Region of Southern Denmark purposefully sampled with regard to gender, years working in general practice and practice form. Interviews were analyzed using systematic text condensation. RESULTS: Most GPs found that using the questionnaire provided a supportive structure to the consultation. The questionnaire helped to bring forward issues of importance to the patients, which might otherwise not have been mentioned and enhanced a patient-centered approach. A few GPs found the use of the questionnaire to be restraining, detracting focus from the patient and impede usual practice. CONCLUSIONS: This study shows that using questionnaires may have the potential to improve clinical cancer care in general practice in relation to needs assessment of cancer patients and the results support current recommendations.

Storytelling as part of cancer rehabilitation to support cancer patients and their relatives.

Previous research on psychosocial support for cancer-related concerns has primarily focused on either patients or their relatives, although limited research is available on how patients and their relatives can be supported together. The aim of this article is to explore the use of storytelling as a part of a residential cancer rehabilitation intervention for patients together with their relatives, with a specific focus on their management of cancer-related concerns. Ten pairs participated in the intervention and data were generated through ethnographic fieldwork, including participant observations, informal conversations and follow-up interviews conducted one month after completing the intervention. Analysis was performed drawing on narrative theory combined with social practice theory. The results demonstrate that the use of storytelling and metaphors intertwined with other course activities, such as dancing and arts & crafts, provided the patients and their relatives with strategies to manage cancer-related concerns, which they were later able to apply in their everyday lives. The study results may be useful to other professionals in clinical practice for rehabilitation purposes for addressing issues of fear and worry.

Providing information about prenatal screening for Down syndrome: a systematic review.

BACKGROUND: In recent decades there have been advances in the options for prenatal screening. Screening programmes for Down syndrome are well established in many countries. It is important that pregnant women are well informed about the benefits and risks of screening. A variety of interventions has been introduced to support pregnant women in their choice of prenatal screening. OBJECTIVE: To summarize the literature using randomized controlled trials to compare the effects of different interventions to provide pregnant women with the information necessary to make an informed choice about screening for Down syndrome. DESIGN: Systematic review METHODS: A systematic search was performed using the PUBMED and EMBASE databases. The search terms included MeSH terms and free text and were combined by Boolean terms (AND, OR) with no restriction on language or time. MAIN OUTCOME MEASURES: Knowledge, informed choice, patient satisfaction, anxiety, depression, conflict and worries. RESULTS: Twelve studies were included in the review. All were characterised by having one or more interventions designed to improve the level of information about prenatal screening for Down syndrome. A positive effect on knowledge and satisfaction from the information received was found in the majority of the studies. The studies were heterogeneous with respect to interventions, methodology and outcome measurements. CONCLUSIONS: Interventions aimed at providing pregnant women with specific information about prenatal screening for Down syndrome can improve their ability to make an informed choice.

Informed choice about Down syndrome screening - effect of an eHealth tool: a randomized controlled trial.

INTRODUCTION: The aim of this study was to evaluate the effect of an eHealth intervention (interactive website) on pregnant women's ability to make an informed choice about Down syndrome screening. MATERIAL AND METHODS: The study was designed as a randomized controlled trial with allocation to an intervention group and a control group in a ratio of 1:1. Subsequent subgroup analysis was conducted. Participants were recruited from 5 August 2013 to 25 April 2014 at Odense University Hospital, Denmark. Inclusion criteria were: pregnant women aged ≥18 years who were invited to participate in Down syndrome screening. Exclusion criteria were: high risk of abortion, psycho-socially vulnerable women, late referral, inability to speak Danish and women declining to participate. The primary outcome was informed choice about Down syndrome screening. The Multidimensional Measure of Informed Choice was used to assess whether the choice was informed or uninformed. RESULTS: A total of 1150 participants were included in the study, of which 910 (79%) completed the questionnaire. Only a minority (30% of the women in the intervention group) actually used the website. There was no significant difference in the groups with respect to making an informed choice. The mean knowledge scores were significantly higher for those in the intervention group who used the intervention. CONCLUSIONS: An interactive website with information about Down syndrome screening had no direct effect on making an informed choice. However, the majority of the pregnant women who used the website were satisfied with the website and would recommend it to others.

How GPs implement clinical guidelines in everyday clinical practice--a qualitative interview study.

BACKGROUND: Clinical guidelines are considered to be essential for improving quality and safety of health care. However, interventions to promote implementation of guidelines have demonstrated only partial effectiveness and the reasons for this apparent failure are not yet fully understood. OBJECTIVE: To investigate how GPs implement clinical guidelines in everyday clinical practice and how implementation approaches differ between practices. METHODS: Individual semi-structured open-ended interviews with seven GPs who were purposefully sampled with regard to gender, age and practice form. Interviews were recorded, transcribed verbatim and then analysed using systematic text condensation. RESULTS: Analysis of the interviews revealed three different approaches to the implementation of guidelines in clinical practice. In some practices the GPs prioritized time and resources on collective implementation activities and organized their everyday practice to support these activities. In other practices GPs discussed guidelines collectively but left the application up to the individual GP whilst others again saw no need for discussion or collective activities depending entirely on the individual GP's decision on whether and how to manage implementation. CONCLUSION: Approaches to implementation of clinical guidelines vary substantially between practices. Supporting activities should take this into account.

Caught in suffering bodies: a qualitative study of immigrant women on long-term sick leave in Norway.

AIMS AND OBJECTIVES: This article explores the issues faced by immigrant women on long-term sick leave due to chronic pain, focusing on their personal perspectives on their daily lives, their bodies and their pain. BACKGROUND: An increasing number of immigrants in Norway present a challenge to the public health service, above all in relation to the health needs of immigrant women, many of whom risk having to take long-term sick leave due to chronic pain. DESIGN: This study has a qualitative design, with participant observation and in-depth interviews. METHODS: Participant observations were carried out from a sample of fourteen immigrant women in an outpatient clinic at a rehabilitation hospital. In addition, qualitative interviews were conducted after the rehabilitation period. A hermeneutic approach was used to understand the meaning of the narrated text. RESULTS: The analysis revealed one main theme, 'Bodies marked by onerous experiences', as well as two subthemes: 'It is in my body' and 'Invisible pain'. The immigrant women struggled with invisible, chronic pain, which they blamed on physically tiring workdays and stressful life situations. Furthermore, they felt that their experiences of discriminative attitudes at the workplace worsened their suffering. CONCLUSIONS: The chronic pain made the immigrant women suffer, because they experienced it as a threatening, incomprehensible and unreal force, without meaning or the ability to be controlled. Their own psychological distress exacerbated their pain. RELEVANCE TO CLINICAL PRACTICE: Immigrant women on long-term sick leave are likely to need special approaches that are closely adapted to their different backgrounds and their unique personal experiences. We recommend culturally appropriate family counselling and collaboration with employers at the women's workplaces.

Sexual functioning and vaginal changes after radical vaginal trachelectomy in early stage cervical cancer patients: a longitudinal study.

INTRODUCTION: Radical vaginal trachelectomy (RVT) offers low complication rate, good survival, and possibility for future childbearing for young women with early stage cervical cancer. However, the literature on quality of life (QOL) and sexual functioning in patients undergoing RVT is scarce. AIM: The aims of this study were to prospectively assess sexual function after RVT and to compare scores of sexual function in patients operated by RVT and radical abdominal hysterectomy (RAH) with those of age-matched control women from the general population. METHODS: Eighteen patients with early stage cervical cancer operated with RVT were prospectively included and assessed preoperatively, and 3, 6, and 12 months postoperatively using validated questionnaires. RAH patients were included consecutively and assessed once at 12 months postsurgery, while an age-matched control group of 30 healthy women was assessed once. MAIN OUTCOME MEASURE: Sexual dysfunction total score as measured by the Female Sexual Function Index (FSFI) was the main outcome measure. RESULTS: During the 12 months posttreatment, RVT patients tended to have persistent sexual dysfunction as measured by FSFI (mean overall score <26.55 at each assessment) and Female Sexual Distress Scale (mean overall score > 11). Sexual worry (P < 0.001) and lack of sexual desire (P = 0.038) were more frequently reported among patients in both treatment groups compared with control women. Sexual activity increased significantly during the observation time for the RVT group (P = 0.023) and reached that of healthy women. Global Health Status score improved over time for the RVT group but never reached that of healthy control women (P = 0.029). CONCLUSIONS: Our data suggest that patients treated with RVT for early stage cervical cancer experience persistent sexual dysfunction up to one year post surgery influencing negatively on their QOL.

Training in motivational interviewing in obstetrics: a quantitative analytical tool.

OBJECTIVE: To examine whether a 3-day training course in motivational interviewing, which is an approach to helping people to change, could improve the communication skills of obstetric healthcare professionals in their interaction with obese pregnant women. DESIGN: Intervention study. SETTING: The Region of Southern Denmark. METHODS: Eleven obstetric healthcare professionals working with obese pregnant women underwent a 3-day course in motivational interviewing techniques and were assessed before and after training to measure the impact on their overall performance as well as the effect on specific behavioral techniques observed during interviews. FINDINGS: With a few exceptions, the participants changed their behavior appropriate to the motivational interviewing technique. The participants made more interventions towards the principles of motivational interviewing (adherent and nonadherent interventions). Furthermore, the participants asked fewer closed and more open questions before training in motivational interview. In the assessment of proficiency and competency, most of the participants scored higher after the training in motivational interviewing. CONCLUSIONS: Training in motivational interviewing improves healthcare professionals' proficiency and competency when communicating with obese pregnant women, albeit that the effect was not universal.

The validity of pathology codes for biopsy-confirmed kidney disease in the Danish National Patobank.

Background: This study validates the application of Systematized Nomenclature of Medicine second edition (SNOMED II) codes used to describe medical kidney biopsies in Denmark in encoded form, aiming to support robust epidemiological research on the causes, treatments and prognosis of kidney diseases. Methods: Kidney biopsy reports from 1 January 1998 to 31 December 2018 were randomly extracted from the Danish National Patobank, using SNOMED codes. A 5% sample was selected, and nephrologists assessed the corresponding medical records, assigning each case the applied clinical diagnoses. Sensitivity, specificity, positive predictive values (PPV), negative predictive values and Cohen's kappa coefficient for the retrieved SNOMED codes were calculated. Results: A total of 613 kidney biopsies were included. The primary clinical disease groups were glomerular disease (n = 368), tubulointerstitial disease (n = 67), renal vascular disease (n = 51), diabetic nephropathy (n = 51) and various renal disorders (n = 40). Several SNOMED codes were used to describe each clinical disease group and PPV for the combined SNOMED codes were high for glomerular disease (94%), diabetic nephropathy (85%) and systemic diseases affecting the kidney (96%). Conversely, tubulointerstitial disease (62%), renal vascular disease (60%) and other renal disorders (17%) showed lower PPV. Conclusions: SNOMED codes have a high PPV for glomerular diseases, diabetic nephropathy and systemic diseases affecting the kidney, in which they could be applied for future epidemiological research.
