Methicillin-resistant Staphylococcus aureus infection in palliative care

Antimicrobial use at the end of life: a scoping review

OBJECTIVE

To examine antibiotic use in patients approaching end of life, in terms of frequency of prescription, aim of treatment, beneficial and adverse effects and contribution to the development of antimicrobial resistance.

DESIGN

Scoping review DATA SOURCES: An information scientist searched Ovid MEDLINE, Ovid EMBASE, The Cochrane library, PubMed Clinical Queries, NHS Evidence, Epistemonikos, SIGN, NICE, Google Scholar from inception to February 2019 for any study design including, but not limited to, randomised clinical trials, prospective interventional or observational studies, retrospective studies and qualitative studies. The search of Ovid MEDLINE was updated on the 10 June 2020.

STUDY SELECTION

Studies reporting antibiotic use in patients approaching end of life in any setting and clinicians' attitudes and behaviour in relation to antibiotic prescribing in this population DATA EXTRACTION: Two reviewers screened studies for eligibility; two reviewers extracted data from included studies. Data were analysed to describe antibiotic prescribing patterns across different patient populations, the benefits and adverse effects (for individual patients and wider society), the rationale for decision making and clinicians behaviours and attitudes to treatment with antibiotics in this patient group.

RESULTS

Eighty-eight studies were included. Definition of the end of life is highly variable as is use of antibiotics in patients approaching end of life. Prescribing decisions are influenced by patient age, primary diagnosis, care setting and therapy goals, although patients' preferences are not always documented or adhered to. Urinary and lower respiratory tract infections are the most commonly reported indications with outcomes in terms of symptom control and survival variably reported. Small numbers of studies reported on adverse events and antimicrobial resistance. Clinicians sometimes feel uncomfortable discussing antibiotic treatment at end of life and would benefit from guidelines to direct care.

CONCLUSIONS

Use of antibiotics in patients approaching the end of life is common although there is significant variation in practice. There are a myriad of intertwined biological, ethical, social, medicolegal and clinical issues associated with the topic.

Evaluating the implementation of national recommendations on multidrug-resistant bacterial microorganisms in end-of-life care

INTRODUCTION

In 2017, a national recommendation on multidrug-resistant bacterial microorganisms (MDRO) in end-of-life care was published. In order to monitor the implementation in a hospital-based palliative care unit, a dedicated multidisciplinary working group on MDRO was established. It developed a standard operating procedure and a documentation template (checklist). The aim of the present study is to evaluate the implementation status after one year.

METHODS

A mixed-methods approach was selected. The status of implementation was identified through a survey among staff members. A retrospective routine data analysis was performed. A focus group discussion with members of the working group focused on previous steps, factors conducive to implementation and on remaining problems.

RESULTS

Almost all (18 out of 20) participants (20 out of 29 eligible staff members) knew the national recommendations. Twelve out of 27 recommendations had a high degree of implementation after one year, another 13 recommendations were seen as at least partly integrated into daily routine. For two recommendations the degree of implementation was rated low: (i) "Taking into account any additional time constraint imposed by protection and isolation measures when planning for personnel and bed occupancy", and (ii) "Facilitating the patient's ability to distinguish and recognize team members and family caregivers". Working group members reported improvements since the implementation, whilst reporting some uncertainty prevailing among both staff members and visitors. Inhibitory factors were said to include the complexity of the standard operating procedure, inadequate usage and poor usability of the checklist. Behavioural and cognitive barriers such as anxieties related to transmission and the sense of security caused by the routine use of protective clothing were considered to be strong. Improving the checklist and the standard operating procedure as well as anchoring procedures in daily routine were considered to be the next important steps.

DISCUSSION

The implementation of recommendations is an iterative process and requires the ongoing development of appropriate measures for implementation in the respective institution. A multidisciplinary working group with monitoring tasks is an advantage.

Multidrug-Resistant Organisms in Palliative Care: A Systematic Review

Background: Multidrug-resistant organisms (MDROs) are an important health care issue. Patients in Western societies often present an increased morbidity of chronic conditions accompanied by poor immune status and the use of devices. In particular, patients in palliative care (PC) are at greater risk of MDRO colonization, due to accompanying special devices and being hospitalized. Objective: To gain an overview of the literature regarding MDROs in PC. Design: Systematic review Data sources: On the 19th of October 2019 the databases " PubMed" and " CINAHL" were used to identify studies reporting on MDROs in PC; the search was updated on 16th of May 2020. Results: Seventeen out of 486 articles were included. Six represent qualitative data, 10 quantitative data, and one a mixed methods approach. Prevalence data range from 4.0% to 18%. MDRO colonization has a negative impact on patients and families. It leads to uncertainties and higher workload by staff members. Strategies for the management of MDROs in the field of PC are predominantly available for methicillin-resistant Staphylococcus aureus. Not even half of institutions utilize existing protocols. Recommendations for dealing with MDROs indicate required staff and time resources as well as information, communication, and specific knowledge. Conclusion: There is a great need for studies examining the prevalence of all MDROs in the PC setting. Additionally, not only patients but also a public enlightenment on MDROs should be provided to decrease knowledge gaps and therefore reduce transmission on MDROs.

Addressing multidrug resistant pathogens in pediatric palliative care patients-the nurses point of view: A qualitative study

BACKGROUND

Multidrug resistant pathogens are a large-scale healthcare issue. In particular, children with life-limiting conditions have a significantly increased risk of multidrug resistant pathogen colonization. Official hygiene requirements recommend children, who are colonized with multidrug resistant pathogens, to be isolated. In the context of pediatric palliative care, such isolation adversely affects the aim of social participation. To overcome this challenge of conflicting interests on a pediatric palliative care inpatient unit, a hygiene concept for patients colonized with multidrug resistant pathogens, called PALLINI, was implemented.

AIM

The aim of this study was to identify the nurses' attitudes and opinions toward PALLINI.

METHODS

Nurses (N = 14) from the pediatric palliative care unit were queried in guideline-oriented interviews. Interviews were analyzed qualitatively by means of content analysis.

RESULTS

The following four categories were identified: (1) safety, (2) effort, (3) quality of care, and (4) participation. All categories demonstrated ambivalence by nursing staff regarding PALLINI. Ambivalence arose from guaranteeing infection control versus noncompliance by the families, additional workload for patients with multidrug resistant pathogens versus lack of resources, impaired relationship with the parents versus enabling better care for the child, as well as enabling some limited contact versus the larger goal of genuine social participation. Despite this, nurses reported the importance of arranging everyday-life for the patients so that they experience as much social participation as possible.

CONCLUSION

The implementation of a new hygiene concept is challenging. Despite positive reception of PALLINI from the nurses, ambivalence remained. Addressing these ambivalences may be critical to best implement the new hygiene concept.

'. . . and then no more kisses!' Exploring patients' experiences on multidrug-resistant bacterial microorganisms and hygiene measures in end-of-life care A mixed-methods study

BACKGROUND

In end-of-life care hygiene, measures concerning multidrug-resistant bacterial microorganisms may contradict the palliative care approach of social inclusion and be burdensome for patients.

OBJECTIVES

To integrate patients' perspectives on handling multidrug-resistant bacterial microorganisms at their end of life, their quality of life, the impact of positive multidrug-resistant bacterial microorganisms' diagnosis, protection and isolation measures on their well-being and patients' wishes and needs regarding their care.

DESIGN

A mixed-methods convergent parallel design embedded quantitative data on the patients' multidrug-resistant bacterial microorganisms' trajectory and quality of life assessed by the Schedule for the Evaluation of Individual Quality of Life in qualitative data collection via interviews and focus groups. Data analysis was performed according to Grounded Theory and qualitative and quantitative results were interrelated.

SETTING/PARTICIPANTS

Between March 2014 and September 2015 at two hospitals adult patients diagnosed with multidrug-resistant bacterial microorganisms and treated in a palliative care department or a geriatric ward were included in the sample group.

RESULTS

Patients in end-of-life and geriatric care reported emotional and social impact through multidrug-resistant bacterial microorganisms' diagnosis itself, hygiene measures and lack of information. This impact affects aspects relevant to the patients' quality of life. Patients' wishes for comprehensive communication/information and reduction of social strain were identified from the focus group discussion.

CONCLUSION

Patients would benefit from comprehensible information on multidrug-resistant bacterial microorganisms. Strategies minimizing social exclusion and emotional impact of multidrug-resistant bacterial microorganisms' diagnosis in end-of-life care are needed as well as adaption or supplementation of standard multidrug-resistant bacterial microorganisms' policies of hospitals.

Multidrug-resistant bacterial microorganisms (MDRO) in end-of-life care: development of recommendations for hospitalized patients using a mixed-methods approach

PURPOSE

Palliative care professionals are frequently confronted with patients colonized or infected with MDRO. One major challenge is how to balance necessary isolation measures and social inclusion as one of the main principles of palliative and end-of-life care. To date, MDRO-specific policies and protocols vary widely between institutions.

AIM

provide empirical recommendations on how to deal with hospitalized MDRO patients in end-of-life care.

METHODS

Recommendations were developed based on (i) initial results of face-to-face interviews and focus groups, (ii) impartial experts' comments and consensus on the draft via online survey and (iii) a face-to-face meeting with consortium members to finalize recommendations. Findings of 158 interviews and six focus groups (39 participants) with patients, family caregivers, staff members and institutional stakeholders contributed to the recommendations. The assessments of 17 experts were considered.

RESULTS

In total, 21 recommendations were approved. The recommended strategy in dealing with MDRO at the end of life allows case-based application of protection and isolation measures. MDRO diagnostics and therapy involve screening at admission. The recommendations suggest consideration of required accommodation facilities, provided material as well as staff and time resources. The recommendations further highlight the importance of providing for strategies enabling the patient's social inclusion and provision of verbal and written information about MDRO for patients and family caregivers, transparent medical documentation, and staff member training.

CONCLUSION

The recommendations summarize the perspectives of individuals and groups affected by MDRO at the end of life and provide practical guidance for clinical routine. Further dissemination and implementation requirements are discussed and should contain the evaluation of the knowledge, views, worries, and anxieties of the target groups.

Burden and Management of Multidrug-Resistant Organisms in Palliative Care

Palliative care includes comprehensive strategies to optimize quality of life for patients and families confronting terminal illness. Infections are a common complication in terminal illness, and infections due to multidrug-resistant organisms (MDROs) are particularly challenging to manage in palliative care. Limited data suggest that palliative care patients often harbor MDRO. When MDROs are present, distinguishing colonization from infection is challenging due to cognitive impairment or metastatic disease limiting symptom assessment and the lack of common signs of infection. Multidrug-resistant organisms also add psychological burden through infection prevention measures including patient isolation and contact precautions which conflict with the goals of palliation. Moreover, if antimicrobial therapy is indicated per goals of care discussions, available treatment options are often limited, invasive, expensive, or associated with adverse effects that burden patients and families. These issues raise important ethical considerations for managing and containing MDROs in the palliative care setting.

Nasal carriage of methicillin-resistant Staphylococcus aureus (MRSA) at a palliative care unit: A prospective single service analysis

BACKGROUND

The emergence of multidrug-resistant bacterial microorganisms is a particular challenge for the health care systems. Little is known about the occurrence of methicillin-resistant Staphylococcus aureus (MRSA) and multidrug-resistant Gram-negative bacteria (MDRGNB) in patients of palliative care units (PCU).

AIM

The primary aim of this study was to determine the carriage of MRSA among patients of a PCU at a German University Hospital and to assess whether the positive cases would have been detected by a risk-factor-based screening-approach.

DESIGN

Between February 2014 and January 2015 patients from our PCU were tested for MRSA carriage within 48 hours following admission irrespective of pre-existing risk factors. In addition, risk factors for MRSA colonization were assessed. Samples from the nostrils and, if applicable, from pre-existing wounds were analysed by standardized culture-based laboratory techniques for the presence of MRSA and of other bacteria and fungi. Results from swabs taken prior to admission were also recorded if available.

RESULTS

297 out of 317 patients (93.7%) fulfilled one or more MRSA screening criteria. Swabs from 299 patients were tested. The detection rate was 2.1% for MRSA. All MRSA cases would have been detected by a risk-factor-based screening-approach. Considering the detected cases and the results from swabs taken prior to admission, 4.1% of the patients (n = 13) were diagnosed with MRSA and 4.1% with MDRGNB (n = 13), including two patients with MRSA and MDRGNB (0.6%). The rate of MRSA carriage in PCU patients (4.1%) was elevated compared to the rate seen in the general cohort of patients admitted to our University Hospital (2.7%).

CONCLUSIONS

PCU patients have an increased risk to carry MRSA compared to other hospitalized patients. Although a risk factor-based screening is likely to detect all MRSA carriers amongst PCU patients, we rather recommend a universal screening to avoid the extra effort to identify the few risk factor-negative patients (<7%). As we did not perform a systematic MDRGNB screening, further studies are needed to determine the true prevalence of MDRGNB amongst PCU patients.

Understanding institutional stakeholders' perspectives on multidrug-resistant bacterial organism at the end of life: a qualitative study

Background

Information lacks about institutional stakeholders’ perspectives on management approaches of multidrug-resistant bacterial organism in end-of-life situations. The term “institutional stakeholder” includes persons in leading positions with responsibility in hospitals’ multidrug-resistant bacterial organism management. They have great influence on how strategies on multidrug-resistant bacterial organism management approaches in institutions of the public health system are designed. This study targeted institutional stakeholders’ individual perspectives on multidrug-resistant bacterial organism colonization or infection and isolation measures at the end of life.

Methods

Between March and December 2014, institutional stakeholders of two study centers, a German palliative care unit and a geriatric ward, were queried in semistructured interviews. Interviews were audiotaped, transcribed verbatim, and analyzed qualitatively with the aid of the software MAXQDA for qualitative data analysis using principles of Grounded Theory. In addition, two external stakeholders were interviewed to enrich data.

Results

Key issues addressed by institutional stakeholders (N=18) were the relevance of multidrug-resistant bacterial organism in palliative and geriatric care, contradictions between hygiene principles and patients’ and family caregivers’ needs and divergence from standards, frame conditions, and reflections on standardization of multidrug-resistant bacterial organism end-of-life care procedures. Results show that institutional stakeholders face a dilemma between their responsibility in protecting third persons and ensuring patients’ quality of life. Until further empirical evidence establishes a clear multidrug-resistant bacterial organism management approach in end-of-life care, stakeholders suggest a case-based approach.

Conclusion

The institutional stakeholders’ perspectives and their suggestion of a case-based approach advance the development process of a patient-, family-, staff-, and institutional-centered approach of how to deal with multidrug-resistant bacterial organism-positive patients in end-of-life care. Institutional stakeholders play an important role in the implementation of recommendations following this approach.

The impact of meticillin-resistant Staphylococcus aureus on patients with advanced cancer and their family members: A qualitative study

BACKGROUND

Little is known about the impact of meticillin-resistant Staphylococcus aureus on patients with advanced cancer, such as its impact on the quality of life of this vulnerable group. To date, research on meticillin-resistant Staphylococcus aureus in the palliative care setting has had a quantitative focus.

AIM

The purpose of this study was to explore the impact of a meticillin-resistant Staphylococcus aureus diagnosis on patients and their carers.

DESIGN

This article reports upon a qualitative interview study of nine patients with advanced cancer and meticillin-resistant Staphylococcus aureus and nine family members (n = 18). Framework analysis was used to analyse the data.

SETTING/PARTICIPANTS

Patients and family members of patients with advanced cancer either admitted to the specialist palliative care unit or receiving palliative care in the hospital setting, who had a laboratory confirmed diagnosis of meticillin-resistant Staphylococcus aureus colonisation, were considered for inclusion in the study.

RESULTS

Four themes were identified using framework analysis: reactions to receiving a meticillin-resistant Staphylococcus aureus diagnosis, the need for effective communication of the meticillin-resistant Staphylococcus aureus diagnosis, the enigmatic nature of meticillin-resistant Staphylococcus aureus, and lessons to guide the future care of meticillin-resistant Staphylococcus aureus patients.

CONCLUSION

This article indicates that meticillin-resistant Staphylococcus aureus can have a significant impact on advanced cancer patients and their families. This impact may be underestimated, but early and careful face-to-face explanation about meticillin-resistant Staphylococcus aureus and its implications can help patients and their families to cope better with it. These findings should be considered when developing policy relating to meticillin-resistant Staphylococcus aureus management and infection control in specialist palliative care settings.

Methicillin-resistant Staphylococcus aureus: Prevalence, incidence, risk factors, and effects on survival of patients in a specialist palliative care unit: A prospective observational study

BACKGROUND

Little is known about the impact of methicillin-resistant Staphylococcus aureus in palliative care settings. To date, the clinical impact of methicillin-resistant Staphylococcus aureus in palliative care is unknown.

AIM

To determine prevalence and incidence of methicillin-resistant Staphylococcus aureus colonisation in a specialist palliative care setting, to identify risk factors for methicillin-resistant Staphylococcus aureus colonisation, to determine the eradication success rate and to determine the impact of methicillin-resistant Staphylococcus aureus on survival.

DESIGN

Prospective cohort study.

SETTING/PARTICIPANTS

Data were collected for consecutive admissions to an inpatient palliative care service. Patients were screened for methicillin-resistant Staphylococcus aureus colonisation on admission and 1 week post admission. Methicillin-resistant Staphylococcus aureus eradication was attempted in methicillin-resistant Staphylococcus aureus positive patients.

RESULTS

Data were collected from 609 admissions for 466 individual patients. Admission screening data were available in 95.5%. Prevalence of methicillin-resistant Staphylococcus aureus colonisation was 11.59% (54 patients). One week incidence of methicillin-resistant Staphylococcus aureus colonisation was 1.2%. Risk factors for methicillin-resistant Staphylococcus aureus colonisation were determined using Chi-Squared test and included high Waterlow score (p < 0.01), high palliative performance scale score (p < 0.01), methicillin-resistant Staphylococcus aureus status prior to admission (p < 0.01), admission from hospital (p < 0.05), presence of urinary catheter or percutaneous endoscopic gastrostomy tube (p < 0.05) and poor dietary intake (p < 0.05). Regression analysis did not identify independent risk factors. Methicillin-resistant Staphylococcus aureus was eradicated in 8.1% of admissions, while 46 patients commenced on the protocol (62.2%) died before completing it. Methicillin-resistant Staphylococcus aureus did not significantly impact survival but was significantly associated with having infection episodes and longer length of stay.

CONCLUSION

This study identified risk factors for methicillin-resistant Staphylococcus aureus colonisation in palliative care patients. Methicillin-resistant Staphylococcus aureus was eradicated in 8.1% of patients. Hence, restricting methicillin-resistant Staphylococcus aureus screening to high-risk palliative care patients may be prudent.

Methicillin-resistant Staphylococcus aureus (MRSA) management in palliative care units and hospices in Germany: a nationwide survey on patient isolation policies and quality of life

BACKGROUND

For palliative care settings, little is known about the benefits of specific methicillin-resistant Staphylococcus aureus containment regimens and the burdens patient isolation imposes on affected patients, their families, and professional caregivers.

AIM

To explore the current practice of MRSA management and its impact on inpatients' quality of life as perceived by professional caregivers.

DESIGN

Survey of inpatient palliative care institutions using 23-item questionnaires (infrastructural data: six items, management process: 14, clinical significance: three).

SETTING/PARTICIPANTS

All palliative care units (179) and hospices (181) listed in Germany's directory of palliative care services. The χ(2) test was used to test for differences; significance level: p ≤ 0.05.

RESULTS

229 of 360 questionnaires were returned. More than 90% of the responding institutions employed specific MRSA protocols. Lack of resources was a more important issue for palliative care units than for hospices regarding availability of single rooms (p = 0.002) and staffing (p = 0.004). Compared to hospices, palliative care units more frequently isolated MRSA patients (p = 0.000), actively treated colonization (p = 0.026), assessed the efficacy of eradication (p = 0.000), provided information on MRSA management to patients (p = 0.014) and relatives (p = 0.001), more often restricted patients' activities (p = 0.000), and reported a negative impact on quality of life (p = 0.000).

CONCLUSIONS

Rigorously applied MRSA protocols impose significant burdens at the end of life. Research on clinical outcomes including quality of life may identify interventions of questionable benefit. The issue of handling MRSA should be studied as a model for the management of other highly complex conditions and special needs such as patient isolation.

Prevalence of Methicillin-Resistant Staphylococcus aureus Colonization and Infection in Hospitalized Palliative Care Patients With Cancer

Little is known about the pattern of methicillin-resistant Staphylococcus aureus (MRSA) colonization and infection in hospitalized palliative care (PC) patients. We reviewed 854 admissions for 289 patients with advanced cancer managed by a PC service in a tertiary care hospital. The MRSA screening was performed at least once in 228 (79%) patients, and 21 (9%) of them were MRSA positive. Other cultures were done in 251 (86.8%) patients, and 8 (3%) patients were MRSA positive. The total number of MRSA-positive admissions was 28 (3%), with a median admission duration of 8 days. A substantial proportion of hospitalized PC patients with cancer are MRSA positive. Research is required to study the impact of infection control measures on the quality of PC delivered to MRSA-positive terminally ill patients in hospitals.

[MRSA and MSSA infections in patients operated on for head and neck cancers]

INTRODUCTION

The MRSA and MSSA infections are essential clinical problem. Both of the strains have high virulence (as a result of enzyme and toxin production), what disturbs wound healing as well as a general condition of the patient.

AIM

The purpose of this work was an estimation of the role of MRSA infections among patients operated on for head and neck cancers.

MATERIAL AND METHODS

From 1155 patients treated for head and neck cancers in The Department of Otolaryngology in Poznan in 2006-2007 189 biological samples were taken to carry out a bacteriological examination. The indications for this procedure were symptoms of infection in the operated area, wound healing per secundam and a hectic fever after the surgery. Biological specimens came from: 57 postoperative wounds, 36 tracheotomy areas, 24 tracheoesophageal fistulas, 9 salivary fistulas, 21 oral cavities and pharynxes, 2 noses, 4 ears, 6 central venous catheter areas, 2 gastrostomies, 2 cerebrospinal fluid (CSF) samples, 1 fluid from pleural cavity, 11 blood samples, 12 urine samples, 2 bronchoalveolar lavages (BAL).

RESULTS

37 biological samples were aseptic, in 11 samples there were no pathological cultures, in 141 samples pathological bacterial flora was found. MRSA was found in 6 cultures and MSSA was found in 18 cultures.

CONCLUSIONS

In order to prevent the MRSA infection the Hospital Infections Department was formed. The results of commissioned bacteriological examinations are analyzed by the Department, what enables bacteriological flora observation in the hospital, fast identification of MRSA infected patients, and, what is more, MRSA infections prevention. It also helps to select proper medicaments in empiric antibiotic therapy.

Clinical features of head and neck cancer patients with methicillin-resistant Staphylococcus aureus

CONCLUSIONS

The risk factors for methicillin-resistant Staphylococcus aureus (MRSA) detection in head and neck cancer patients are the duration of hospitalization, intravenous hyperalimentation, prior antibiotic use, and the coexistence of other pathogens.

OBJECTIVES

To shed light on the clinical characteristics of MRSA-positive inpatients with head and neck cancers. The secondary goal was to evaluate risk factors for MRSA detection in comparison with methicillin-sensitive S. aureus (MSSA).

PATIENTS AND METHODS

Sixty-one consecutive inpatients with head and neck cancers with S. aureus detection were analyzed based on their medical records. The antimicrobial susceptibility of isolated S. aureus was tested by the broth microdilution method.

RESULTS

MRSA and MSSA were detected in 46 (75.4%) and 15 (24.6%) of the 61 patients, respectively. There was no significant difference in the male/female ratio, age, primary site, comorbidity, cancer stage, cancer treatment, or 5-year survival rate between the MRSA and MSSA groups. Compared with the MSSA group, the MRSA group had significantly longer hospitalization periods and intervals between admission and MRSA detection, as well as significantly greater likelihood of intravenous hyperalimentation, prior antibiotic use, and co-isolation of other pathogens. Isolated strains of MRSA were thoroughly sensitive to vancomycin and arbekacin and moderately sensitive to minocycline.

A survey of methicillin-resistant Staphylococcus aureus (MRSA) management in hospices/palliative care units

A questionnaire-based survey was performed of the protocols adopted by specialist palliative care in-patient units in southern England for the management of methicillin-resistant Staphylococcus aureus (MRSA). An 87% response rate was obtained from a total of 63 units. Ninety-five percent of the responding units had a protocol for MRSA management, but staff training in its contents was provided in only 59%. Some form of screening for MRSA was carried out by 13% of units. Infection control precautions taken varied between units and according to whether a patient was colonized or infected with MRSA. Although 86% carried out some form of isolation of patients with known or suspected MRSA infection, only 46% restricted their activity within the unit. However, 41 % of respondents felt that protocols to eradicate MRSA colonization were not relevant to hospices. The impact of MRSA infection or colonization on a palliative care population in terms of quality of life and morbidity remains unknown.

An investigation of MRSA infection in a hospice

This study investigated the prevalence of methicillin-resistant Staphylococcus aureus (MRSA) carriage and infection among patients admitted to a hospice. Under the existing policy at this hospice, only patients admitted from hospital wards where MRSA is known to be present are screened for MRSA prior to transfer. Hence the investigators were keen to study patients transferred from settings other than this. One hundred and twenty patients, all either from the community or from hospital wards without known MRSA, were entered into the study ('study group') and were swabbed for MRSA on admission to the hospice. Swabbing was continued at weekly intervals until discharge or death. Of the 120 patients, seven (5.8%) were MRSA positive on admission. A further four patients who were negative on admission showed MRSA on later swabs. Another two patients developed symptomatic infections during admission that were proven to be due to MRSA, but neither of these had shown MRSA on any swabs taken during the study. During the study period, a separate group of 156 patients was swabbed routinely before transfer from hospital wards where MRSA was known to be present in accordance with hospice policy ('non-study group'). Of these patients, 11 (7.1%) were found to be colonized with MRSA but none developed associated symptomatic infection. It appears that the risk of symptomatic infection with MRSA in hospice patients is low, and the burden placed on this vulnerable group by conventional eradication regimes may be disproportionate to any benefit derived.

Management of infections in palliative care patients with advanced cancer

To characterize infections and their management in oncology patients at the end of life, we conducted a review of the literature. Eight studies assessing infection in 957 patients with various malignancies were identified. Forty-two percent of terminally ill patients developed infections in the final phase of care. The greatest frequency of treatment with antibiotics occurred in acute care hospitals. Enterobacteriaceae and S. aureus were the most frequently isolated bacteria, and urinary and respiratory tracts the most frequently involved sites of infection. A total of 19-39% of individuals with suspected infection and advanced cancer died. The decision whether to treat or not in the palliative care setting may be complex and requires an individualized approach. Further research in this area will help develop a consensus for management that will facilitate education of students and residents regarding complex decisions of care of infections at the end of life.

NHPCO Task Force Statement on the Ethics of Hospice Participation in Research

There is an urgent need for robust empirical data to guide the assessment and treatment of patients near the end of life. Because they are important providers of end-of-life care in this country, hospices have an important role to play in facilitating this research. However, hospices may also face considerable ethical challenges in doing so. This task force statement begins by discussing the importance of hospices' potential contributions to research. Next, we describe ways in which characteristics of hospice patients, and hospices' structure, create ethical challenges that may limit these contributions. We conclude by proposing ways in which hospices and national professional organizations can begin to overcome some of these challenges.

Efficacy of two non-antibiotic therapies, oxytocin and topical liniment, against bovine staphylococcal mastitis

Eight cows were challenged by a single quarter intramammary infusion of a relatively low-virulence strain of Staphylococcus aureus on four occasions five weeks apart and, after each challenge, each cow received one of four treatments, according to a duplicated Latin-square design. The treatments were massage alone (negative control), massage with a proprietary liniment, oxytocin, and a single course of a proprietary intramammary antibiotic. The massage treatments were applied at every milking for three weeks, oxytocin was given for one week, and the antibiotic was given after three successive milkings. Milk samples were collected immediately before and for three weeks after each challenge, and a scoring system was used to quantify the presence of bacteria during the whole of the period. None of the treatments completely eliminated bacteria from all the cows. Relative to the negative control, the liniment had no significant effect, but both oxytocin and the antibiotic reduced the numbers of bacteria significantly and did not differ significantly in efficacy.
