Epidemiology of catheter-related infections in adult patients receiving home parenteral nutrition: A systematic review

BACKGROUND AND AIMS Catheter-related infection (CRI) is the most common and serious complication for adult patients receiving home parenteral nutrition (HPN). Our aim is to provide epidemiological data on infection incidence, infecting pathogens and contributing risk factors. METHODS Four electronic databases (Embase, Medline, IPA, CINAHL) were screened for eligible studies published between 1970 and March 2012. Methodological quality was evaluated and terminology/definitions were re-categorized. RESULTS Thirty-nine studies were included. Extensive variability was observed in terminology/definitions as well as in expression of CRI rate. After correct interpretation of definitions, overall catheter-related bloodstream infection rate (CRBSI) ranged between 0.38 and 4.58 episodes/1000 catheter days (median 1.31). Gram-positive bacteria of human skin flora caused more than half of infections. An analysis of the reported risk factors showed that the origin of a CRBSI is often multifactorial. The risk factors were related to the patient, the venous access device, the education, HPN therapy and follow-up. CONCLUSIONS This review on CRI in adult HPN patients revealed that included studies are of low quality and used poorly described risk factors and different definitions. The human skin flora caused most of infections; therefore, hand hygiene and training remain essential.

Guidelines recommendations on care of adult patients receiving home parenteral nutrition: a systematic review of global practices.

BACKGROUND & AIMS Because home parenteral nutrition (HPN) in adult patients can give rise to a variety of complications, good guidance is necessary. To achieve this, clarity and consistency in guidelines are essential. The aim of this review is to identify and compare evidence-based guidelines, and to compile a list of main recommendations, according to their evidence-based grade. METHODS We searched Medline and the international guideline database for HPN guidelines, performed a content analysis of retrieved guidelines, and evaluated their quality. We then compiled a comparative table of guideline recommendations along with their assigned level of evidence. SUMMARY OF RESULTS Six systematically developed evidence-based guidelines and one expert opinion-based standard for home care were retrieved. Of these guidelines, two were exclusively devoted to HPN. Although the guidelines generally covered the same topics, most did not provide information on intravenous medication, bone metabolic disease, and indications in patients with malignant disease. Moreover, we found grading discrepancies among various guidelines, as identical recommendations were often labeled with different grades. CONCLUSION Our comparison of guidelines and standards for HPN revealed substantial differences among recommendations. Identification of these discrepancies and omissions should facilitate the development of more comprehensive and better justified guidelines in the future.

Development of quality of care interventions for adult patients on home parenteral nutrition (HPN) with a benign underlying disease using a two-round Delphi approach

BACKGROUND & AIMS HPN patients with benign diseases deserve professional care as they have to deal with complex techniques and risk potentially dangerous complications. The aim was to highlight main outcome quality indicators and to develop a set of key interventions to direct multidisciplinary teams in providing qualitative care. METHODS A two-round Delphi approach was used to build consensus on the most important outcome indicators and on 59 interventions identified in existing guidelines on HPN. Comments and interventions newly identified in the first round were co-evaluated in the second round. RESULTS 29 experts from 9 countries completed the two-round Delphi approach. The outcome indicators rated as the most important are 1) incidence of catheter-related infections, 2) incidence of readmission and quality of life (shared second place) and 3) incidence of dehydration. Sixty eight of a total of 89 interventions were considered as important for the quality of care, of which 46 are based on published guidelines and 22 were newly suggested by the Delphi panel. CONCLUSIONS Using a two-round Delphi approach, consensus was reached for the majority of interventions concerning HPN patients with benign diseases. This set of 68 interventions could be of use as a starting point for quality-improvement programs.

Quality of care for cancer patients on home parenteral nutrition: development of key interventions and outcome indicators using a two-round Delphi approach

PurposeClear recommendations on how to guide patients with cancer on home parenteral nutrition (HPN) are lacking as the use of HPN in this population remains a controversial issue. Therefore, the aims of this study were to rank treatment recommendations and main outcome indicators to ensure high-quality care and to indicate differences in care concerning benign versus malignant patients.MethodsTreatment recommendations, identified from published guidelines, were used as a starting point for a two-round Delphi approach. Comments and additional interventions proposed in the first round were reevaluated in the second round. Ordinal logistic regression with SPSS 2.0 was used to identify differences in care concerning benign versus malignant patients.ResultsTwenty-seven experts from five European countries completed two Delphi rounds. After the second Delphi round, the top three most important outcome indicators were (1) quality of life (QoL), (2) incidence of hospital readmission and (3) incidence of catheter-related infections. Forty-two interventions were considered as important for quality of care (28/42 based on published guidelines; 14/42 newly suggested by Delphi panel). The topics ‘Liver disease’ and ‘Metabolic bone disease’ were considered less important for cancer patients, together with use of infusion pumps (p = 0.004) and monitoring of vitamins and trace elements (p = 0.000). Monitoring of QoL is considered more important for cancer patients (p = 0.03).ConclusionUsing a two-round Delphi approach, we developed a minimal set of 42 interventions that may be used to determine quality of care in HPN patients with malignancies. This set of interventions differs from a similar set developed for benign patients.
