Hematopoietic Stem Cell Transplantation Impact on Patients' Perceived Quality of Life: A Longitudinal Study

OBJECTIVE

The aim of this paper was to evaluate the quality of life of adult patients with onco-hematological disease treated with hematopoietic stem cell transplantation up to two years post-transplantation.

METHOD

A quantitative, observational, longitudinal, and analytical study was conducted with 121 participants diagnosed with onco-hematological cancer who underwent hematopoietic stem cell transplantation between October 2017 and September 2019, with a 2-year post-transplantation follow-up, of whom only 39 completed the study. The Functional Assessment of Cancer Therapy-Bone Marrow Transplantation (FACT-BMT) questionnaire and its subscales, Functional Assessment of Cancer Therapy-General (FACT-BMT) and Functional Assessment of Cancer Therapy Trial Outcome Index (FACT-TOI), developed by the Functional Assessment of Chronic Illness Therapy (FACIT) and validated for Spain, were used to assess quality of life.

RESULT

The average age for hematopoietic stem cell transplantation was 54 years, with a majority of male participants. The evaluation of quality of life showed a decrease at the time of hospital discharge, followed by a progressive improvement up to one year after the transplantation. There was a significant difference in the quality of life questionnaire scores between both sexes during all stages of the research, with higher scores in male participants. The length of hospital stay significantly affected patients' physical and functional well-being, and marital status was related to differences in the perception of quality of life.

CONCLUSIONS

Despite the initial decrease in quality of life for patients undergoing hematopoietic stem cell transplantation, levels of quality of life similar to baseline are regained one year after the transplantation. Sociodemographic variables are related to how these patients perceive their quality of life. However, further studies with a larger sample size are needed for more precise results.

Post-Transplant Complications in Patients Undergoing Autologous Hematopoietic Cell Transplantation (HCT)-A Comparative Analysis of Home Care versus Hospitalized Patients

Background and Objectives: The increase in indications for hematopoietic cell transplants (HCTs) has led to the development of new care options after said transplant, such as home care after transplantation, which improves the patients' quality of life. The main purpose of this research is to analyze the differences in the appearance of post-transplant complications between patients having underwent autologous HCT with at-home post-transplant modalities and those under in-hospital post-transplant care. Materials and Methods: An observational, analytical, longitudinal, and retrospective study of cases and controls. All transplanted people in the domiciliary model since 2020 are included as cases (20 subjects). For each case, two controls (40 subjects) are proposed among patients who received an autologous transplant in a hospital in the last five years with a similar demographic and pathological base profile in each case. Results: No significant differences were found between cases and controls, except for the Karnofsky value, which was higher in people receiving home treatment (91.7% vs. 87.74%; p = 0.05). The average number of days of the process post-transplantation was more significant at home (processing days 22.4 ± 2.6; post-transplantation days of 16.4 ± 2.08 versus 21.21 ± 4.18, with a mean of 15.51 ± 3.96 days post-transplant (days of the process p = 0.022; days post-transplant p = 0.002)). There is a more significant presence of neutropenic fever, mucositis, and positive blood cultures in the post-transplant patients who remain in the hospital. In contrast, the patients receiving home care post-transplantation undergo significantly more weight loss. Regarding the odds ratio of the appearance of adverse events, in the hospital setting, it is up to 8.5 times more likely to encounter neutropenic fever, 4.63 times more likely for mucositis, and 6.65 times more likely for the presence of pathogens in blood cultures. Conclusions: The home care modality in the post-transplant phase does not show an inferiority in conditions in the management and safety of the patient concerning the appearance of adverse events. However, more significant weight loss is detected in patients at home, and an increased risk of episodes of neutropenic fever, mucositis, and positive blood cultures for patients in hospital settings.

Application of the Delphi Method for Content Validity Analysis of a Questionnaire to Determine the Risk Factors of the Chemsex

Chemsex is understood as "the intentional use of stimulant drugs to have sex for an extended time among gay, bisexual, and other men who have sex with men". It is a public health problem because of the increased incidence of cases and because of the consequences on the physical and mental health of those who practice it.

AIM

This study aimed to analyze, with the help of the Delphi method, the content validity of a new instrument to assess the risk of behaviors associated with the chemsex phenomenon.

METHOD

First, a bank of items identified from the literature was elaborated. Secondly, 50 experts with knowledge of the chemsex phenomenon at the national level were contacted. A Delphi group was formed with them to carry out two rounds of item evaluation. The linguistic evaluation (comprehension and appropriateness) was assessed using a Likert scale from 1 to 5 for each item. Items that did not reach a mean score of 4 were eliminated. Content assessment was calculated using each item's content validity index (CVI) and Aiken's V (VdA). A minimum CVI and VdA value of 0.6 was established to include the items in the questionnaire.

RESULTS

A total of 114 items were identified in the literature. In the first round of Delphi evaluation, 36 experts evaluated the items. A total of 58 items were eliminated for obtaining a CVI or VdA of less than 0.6, leaving 56 items. In a second Delphi round, 30 experts re-evaluated the 56 selected items, where 4 items were eliminated for being similar, and 10 items were also eliminated for not being relevant to the topic even though they had values higher than 0.6, leaving the scale finally composed of 52 items.

CONCLUSION

A questionnaire has been designed to assess the risk of behaviors associated with the chemsex phenomenon. The items that make up the questionnaire have shown adequate content and linguistic validity. The Delphi method proved to be a helpful technique for the proposed objective.

Knowledge about Palliative Care and Attitudes toward Care of the Dying among Primary Care Nurses in Spain

Objective: To analyze the knowledge in palliative care and the attitudes toward caring for the dying of nurses who carry out their professional activity in primary care in Spain. Design: A cross-sectional descriptive observational study was carried out among Spanish primary care centers. Participants: A total of 244 nurses who had completed their primary care work and agreed to participate in this study were included. Main measurements: The level of knowledge in palliative care was analyzed using the PCQN-SV scale, and attitudes toward care of the dying were measured with the FATCOD-S scale, both of which are instruments that are validated in Spain. Results: Regarding the level of knowledge in palliative care, at a global level, the results revealed that 60% of the answers in the PCQN-SV were correct, with different results for each of the three subscales that compose it. When analyzing the attitudes of primary care nurses toward the care of the dying, an average of 132.21 out of 150 was obtained, representing a positive attitude. On the other hand, when analyzing these results in terms of knowledge and attitudes according to the population’s characteristics, we see that participants with both experience and training in palliative care present a better level of knowledge and a higher score regarding their attitudes toward care of the dying. However, the differences are only significant regarding the level of knowledge in palliative care. When analyzing the data from the two scales together, it is noteworthy that the participants with the most positive attitudes (highest scores on the FATCOD-S) also have the highest percentages of correct answers on the PCQN-SV.

Importance of nutritional assessment tools in the critically ill patient: A systematic review

Background

Among the risks of the critically ill patient, one of the aspects to be taken into account is the high probability of occurrence of malnutrition risk (40-50%). This process leads to increased morbimortality and worsening. The use of assessment tools allows the individualization of care.

Objective

To analyze the different nutritional assessment tools used during the admission of critically ill patients.

Methods

Systematic review of the scientific literature related to the nutritional assessment of critically ill patients. Between January 2017 and February 2022, articles were rescued from the electronic databases "Pubmed," "Scopus," "CINAHL" and "The Cochrane Library"; which will analyze which instruments are used during nutritional assessment in the ICU, as well as their impact on mortality and comorbidity of patients.

Results

The systematic review was made up of 14 scientific articles that met the selection criteria, obtained from seven different countries. The instruments described were: mNUTRIC, NRS 2002, NUTRIC, SGA, MUST and the ASPEN and ASPEN criteria. All the included studies demonstrated beneficial effects after nutritional risk assessment. mNUTRIC was the most widely used assessment instrument, with the best predictive validity for mortality and adverse outcomes.

Conclusion

The use of nutritional assessment tools makes it possible to know the real situation of patients, and by objectifying situations, to allow different interventions to improve the nutritional level of patients. The best effectiveness has been achieved using tools such as mNUTRIC, NRS 2002 and SGA.

Level of knowledge and attitudes towards palliative care for people with advanced dementia in Spain: role of professional and academic factors

BACKGROUND

Providing quality end-of-life care to individuals with advanced dementia is crucial. To date, little attention has been paid to palliative care knowledge and attitudes toward palliative care for people with advanced dementia in Spain Objectives: To investigate the knowledge of and attitudes toward palliative care for advanced dementia among registered nurses and physicians in Spain.

DESIGN AND METHODS

A descriptive, cross-sectional survey design was used. This study included a convenience sample of 402 nurses (n = 290) and physicians (n = 112). Two instruments were administered: demographic characteristics and Spanish version of the Questionnaire of Palliative Care for Advanced Dementia (qPAD-SV). Descriptive statistics and multiple regression were used for data analysis.

RESULTS

Overall, the nurses and physicians had moderate mean scores for both knowledge of and attitudes regarding palliative care for advanced dementia. Physicians had a higher level of knowledge (p<0.05) compared to nurses. Additionally, physicians and nursing staff who had professional experience/education in geriatrics and those who had received palliative care and hospice training had greater (p<0.01) knowledge of palliative care. In addition, healthcare professionals who had received dementia care training and who had worked in nursing homes had higher levels (p<0.05) of knowledge and attitudes toward palliative care.

CONCLUSION

This study indicates the need to provide nurses and physicians with more education for select groups of professionals who have had limited education and experience in caring for older adults with advanced dementia.

Usefulness of Midline Catheters versus Peripheral Venous Catheters in an Inpatient Unit: A Pilot Randomized Clinical Trial

Canalization of vascular accesses is one of the most used techniques in hospitalization units. When talking about peripherally inserted catheters, we can differentiate between peripheral intravenous catheters (PIVC), midline catheters, and long peripheral catheters (LPC). Midline catheters are rarely used despite being recommended for intravenous therapies lasting more than six days. This research is a pilot study of a longitudinal clinical trial. It aims to compare the complications associated with intravenous therapy between the control group (CG) with a PIVC and the experimental group (EG) with a midline in an Internal Medicine Unit of a Spanish hospital for three months. In this study, 44 subjects participated, 25 in the CG and 19 in the EG. The duration of cannulation was longer in the experimental group (8.13 days vs. 3.22, p < 0.001), and the appearance of phlebitis was more significant in the control group (19 patients in CG and 25 patients in EG). Midlines have presented a longer duration of cannulation and fewer complications than the PIVC. This protocol was registered with ClinicalTrials.gov (NCT05512117).

Palliative Care Needs and Clinical Features Related to Short-Term Mortality in Patients Enrolled in a Heart Failure Unit

(1) Background: Heart failure (HF) is a chronic and complex pathology requiring continuous patient management due to clinical instability, associated comorbidity, and extensive pharmacological treatment. Its unpredictable course makes the advanced stages challenging to recognize and raises the need for palliative care. This study aims to identify palliative care needs in HF patients and describe clinical features related to short-term mortality. (2) Methods: A descriptive, observational, cross-sectional, and retrospective study was carried out in an HF unit of a Spanish tertiary hospital. Patients’ socio-demographic and clinical data were collected from clinical records, and different instruments were used to establish mortality risks and patients’ needs for palliative care. Subsequently, univariate and bivariate descriptive analyses were performed. A binary logistic regression model helped to determine variables that could influence mortality 12 months after admission to the Unit. (3) Results: The studied population, sixty-five percent women, had an average age of 83.27 years. Among other clinical characteristics predominated preserved ejection fraction (pEF) and dyspnea NYHA (New York Heart Association) class II. The most prevalent comorbidities were hypertension and coronary heart disease. Forty-nine percent had a low–intermediate mortality risk in the following year, according to the PROFUND index. The NECPAL CCOMS-ICO© instrument identified subjects who meet the criteria for palliative care. This predictive model identified NECPAL CCOMS-ICO© results, using beta-blockers (BB) or AIIRA (Angiotensin II receptor antagonists) and low glomerular filtration rate (GFR) as explanatory variables of patients’ mortality in the following year. (4) Conclusions: The analysis of the characteristics of the population with HF allows us to identify patients in need of palliative care. The NECPAL CCOMS-ICO© instrument and the PROFUND have helped identify the characteristics of people with HF who would benefit from palliative management.

Knowledge and Attitudes towards Palliative Care: Validation of the Spanish Version of Questionnaire on Palliative Care for Advanced Dementia

Background: Palliative care is essential in the care of people with advanced dementia, due to the increasing number of patients requiring care in the final stages of life. Nurses need to acquire specific knowledge and skills to provide quality palliative care. The Questionnaire on Palliative Care for Advanced Dementia (qPAD) is useful for assessing knowledge and attitudes toward palliative care, but its adaptation to the Spanish language and analysis of its effectiveness and usefulness for the Spanish culture is lacking. Objective: To report on the Spanish language adaptation and psychometric analysis of the qPAD. Methods: The Questionnaire on Palliative Care for Advanced Dementia Spanish version (qPAD-SV) was obtained from a process that included translation, back-translation, comparison with other language versions, expert review, and pilot study. Content validity, criterion validity, and reliability of the questionnaire were analyzed. The difficulty and discrimination indices of items composing the knowledge subscale were also calculated. Results: Adequate content validity index obtained after the analysis of qPAD-SV by a heterogeneous group of experts was found (overall CVI = 0.96; 0.95 for the Knowledge subscale and 0.99 for the Attitudes subscale). Significant correlations with the Palliative Care Knowledge test (rho = 0.368, p < 0.001) and Self-Efficacy in Palliative Care Scale (rho = 0.621, p < 0.001) show an adequate criterion validity. Cronbach’s alpha coefficients for the Knowledge subscale (0.60) and the Attitudes subscale (0.91) supported the reliability of the qPAD-SV. The questionnaire had an overall difficulty index of 0.71, with three items that could be considered difficult or very difficult, and eleven items that could be considered very easy. Discussion: Although it shows internal consistency, validity, and difficulty indices similar to those obtained by qPAD versions in other languages, a reformulation of the items with lower content validity or discrimination indices and those that show difficulties in their comprehension is an aspect to be taken into account to improve this tool. Conclusions: The qPAD-SV is a useful instrument in Spanish to measure the knowledge of Spanish nurses in palliative care and is suitable for international comparisons.

Spanish Version of the Scale “Eventos Adversos Associados às Práticas de Enfermagem” (EAAPE): Validation in Nursing Students

Healthcare carried out by different health professionals, including nurses, implies the possible appearance of adverse events that affect the safety of the patient and may cause damage to the patient. In clinical practice, it is necessary to have measurement instruments that allow for the evaluation of the presence of these types of events in order to prevent them. This study aims to validate the “Eventos adversos associados às práticas de enfermagem” (EAAPE) scale in Spanish and evaluate its reliability. The validation was carried out through a cross-sectional study with a sample of 337 nursing students from the University of Valencia recruited during the 2018–19 academic year. An exploratory factor analysis was carried out using principal components and varimax rotation. The factor analysis extracted two factors that explained 32.10% of the total variance. Factor 1 explains 22.19% and refers to the “adverse results” of clinical practice (29 items), and factor 2 explains 9.62% and refers to “preventive practices” (24 items). Both factors presented high reliability (Cronbach’s alpha 0.902 and 0.905, respectively). The Spanish version of the EAAPE is valid and reliable for measuring the perception of adverse events associated with nursing practice and the presence of prevention measures.

Spanish Nurses' Knowledge about Palliative Care. A National Online Survey

(1) Background: Nurses can find people with advanced diseases or in their last days of life during their professional careers and in many different care settings. For this reason, they need to have at least a basic level of palliative care education since they are the professional cohort treating these patients in a very close way. This research aims to determine the level of knowledge in palliative care of Spanish nurses and establish any possible difference based on their experience and training in palliative care. (2) Methods: A cross-sectional design using survey methods (distributed an online questionnaire) aimed at Spanish registered nurses. A validated questionnaire (PCQN-SV) was used to determine the level of knowledge in palliative care; information on some variables to characterize the population was also collected (experience and education in palliative care, years of professional experience, academic level, and others). Uni and bivariate descriptive analyses were performed. A binary logistic regression model was also developed to identify those variables that influenced obtaining results higher than the population’s average. (3) Results: Spanish nurses have a medium–low level of knowledge in palliative care, higher in those who have previous experience or education in this area. Statistically significant differences were also found according to the area in which their caring activity was developed. (4) Conclusions: It is necessary to implement strategies for the basic training of nursing professionals in palliative care to offer quality care to people in advanced stages of illnesses or at the end of their lives.

Analysis of Spanish nursing students' knowledge in palliative care. An online survey in five colleges

Along their professional career, nurses can find patients who require palliative care (PC). It is necessary to have at least a basic education in this area, that should be acquired during their university education. The objective of this descriptive online-survey set in five nursing Colleges was to analyze Spanish nursing students' knowledge in PC, offering an image of the status of education in PC. 619 students took an online questionnaire with the Spanish version of the Palliative Care Quiz for Nurses (PCQN-SV), which also collected information about their education in the field of PC. Univariate and bivariate analyses were performed, and a predictive binary logistic regression model was developed. Students obtained an average 45.65% of right answers in PCQN-SV, with differences related to the college and academic year in which they were enrolled and to their education in PC. In the regression model having theoretical education in PC (OR = 1.70) and academic year (OR = 1.35) showed to be both predictors of getting a result in PCQN-SV over 45% of correct answers. This study showed that Spanish nursing students have a medium-low level of knowledge in PC, and it also supports the need to develop a common framework for nurses' education in PC.

Health Assets, Vocation and Zest for Healthcare work. A Salutogenic Approach to Active Coping among Certified Nursing Assistant Students

People's health assets (HA) mapping process and design dynamization strategies for it are paramount issues for health promotion. These strategies improve the health heritage of individuals and communities as both the salutogenic model of health (SMH) and health assets model (HAM) defend. Connecting and mobilizing HA and strengthens the 'sense of coherence' (SOC) are both related to enhancing stress active and effective coping strategies. This study aims to describe the HA present in a population of certified nursing assistant students (n = 921) in Spain and then to explore their relationships with the SOC, the motivation to choose healthcare studies and their academic performance. A great variety of HA were identified and mapped. Findings showed that individuals with greater motivation towards self-care and 'caring for others' as internal HA, possessed higher SOC levels and a strong vocation for healthcare work. Differences in HA were identified according to gender, age and employment situation. Consistent connections between the care-relation factor and vocational factor with interpersonal and extrapersonal HA were reported. Evidence and results substantiated the salutogenic and asset-based approach as a proper strategy to strengthen SOC, dynamize their HA map, reinforce the sense of calling and enable Certified Nurse Assistant (CNA) students to buffer against caregiving-related stress and thrive in their profession.

Sleep quality and its association with substance abuse among university students

OBJECTIVE

Poor sleep is one of the greatest health problems with social significance whose prevalence started early in adolescence. The relationship between poor sleep quality and the use of alcohol and illicit substances among university students has not been studied. Our study aimed to determine these relationships and the factors influencing the risk of poor sleep in students from health sciences degrees which are the future healthcare providers.

PATIENTS AND METHODS

A cross-sectional study performed in European university students (n = 676). Sleep quality was assessed by measuring insomnia symptoms with the Athens insomnia scale (AIS). The CRAFFT screening test and AUDIT test were used to measure the use of substances of abuse.

RESULTS

Insomnia symptoms were highly prevalent (40.2%) and more common among the youngest students (p = 0.012), who had been studying at the university for less time (p = 0.018), and had high levels of illicit drug use (p = 0.037). Good sleep quality represented a significant protective factor for problematic drug use, with an OR of 0.8 (CI95%: 0.76-0.99). In contrast, the category "not having a job" represents risk 1.2 times higher (CI95%: 1.025-1.557) for problematic drug use. The CRAFFT score significantly predicted higher insomnia symptoms (AIS ≥ 6), yielding an OR of 1.2 (CI95%:1.10-1.32, p < 0.001).

CONCLUSIONS

Poor sleep quality is common in university students. There is an inverse association between higher insomnia symptoms and illicit drug abuse being a good sleep qualitya protective factor against problematic use of illicit drugs. Several personal and social consequences of illicit drug use are related to poor sleep in this population and it deserves future studies and interventions in order to improve both problems.

Preoperatory Anxiety in Patients Undergoing Cardiac Surgery

Anxiety is a feeling of discomfort produced in face of an unknown event, as an impending cardiac surgery, that can lead to inconveniences in the intervention and subsequent recovery. Being the purpose of this research to analyze pre-surgical anxiety, a descriptive cross-sectional study among patients undergoing cardiac surgery was carried out. Data about sociodemographic variables were collected and the level of anxiety prior to surgery was assessed using the STAI-S scale. Subsequently, descriptive data analyses were performed, relationships among variables were analyzed, and a binary logistic regression model was developed in order to analyze the role of the variables involved in the development of preoperative anxiety. Sixty subjects were finally included; more than 80% had a moderate to high level of anxiety. 26.7% underwent valve surgery and 47% underwent coronary artery bypass graft (CABG) surgery, in the latter case presenting higher levels of anxiety. Statistically significant relationships were found among the level of anxiety and (a) level of studies, (b) first surgical intervention, and (c) the rating given to their previous surgical experience. We concluded that preoperative anxiety in people undergoing cardiac surgery is high and yet it is an underestimated phenomenon. The relationship between the received information and their anxiety level is inversely proportional, so that people programmed for cardiac surgery should be provided with all the information they required, through an individualized intervention.

Utility of social networks and online data collection in nursing research: Analysis of Spanish nurses' level of knowledge about palliative care

INTRODUCTION

Internet-based social networks are used by nurses with different purposes, including the creation of working groups and to share and create knowledge.

PURPOSE

To evaluate the utility of social networks in the dissemination of an online questionnaire and to measure Spanish RNs' knowledge about palliative care.

METHODS

A descriptive cross-sectional study was carried out. Using social networks we distributed an online questionnaire with the Spanish version of Palliative Care Quiz for Nurses (PCQN-SV) throughout August 2015.

RESULTS

A direct relationship between the number of responses and the questionnaire's apparitions in each social network was found. Comparing the results obtained by the 446 RNs participating in this study with those obtained in the study to pilot the PCQN-SV we identify that differences found are related to the participants' features (years of experience and hours of training in palliative care) and not to the type of questionnaire they answered.

CONCLUSIONS

Social networks have shown to be a useful tool for nursing research by its ability, to recruit participants as well as to collect data, so their role as an instrument of research should be considered.

Knowledge in palliative care of nursing professionals at a Spanish hospital

Objective:

to determine the level of knowledge in palliative care of nursing staff at a Spanish tertiary care hospital.

Method:

descriptive, cross-sectional study. Data were collected about the results of the Spanish version of the Palliative Care Quiz for Nurses (PCQN), sociodemographic aspects, education level and experience in the field of palliative care. Univariate and bivariate descriptive analysis was applied. Statistical significance was set at p < 0.05 in all cases.

Results:

159 professionals participated (mean age 39.51 years ± 10.25, with 13.96 years ± 10.79 of professional experience) 54.7% possessed experience in palliative care and 64.2% educational background (mainly basic education). The mean percentage of hits on the quiz was 54%, with statistically significant differences in function of the participants’ education and experience in palliative care.

Conclusions:

although the participants show sufficient knowledge on palliative care, they would benefit from a specific training program, in function of the mistaken concepts identified through the quiz, which showed to be a useful tool to diagnose professionals’ educational needs in palliative care.

An instrument to measure nurses' knowledge in palliative care: Validation of the Spanish version of Palliative Care Quiz for Nurses

BACKGROUND

Palliative care is nowadays essential in nursing care, due to the increasing number of patients who require attention in final stages of their life. Nurses need to acquire specific knowledge and abilities to provide quality palliative care. Palliative Care Quiz for Nurses is a questionnaire that evaluates their basic knowledge about palliative care. The Palliative Care Quiz for Nurses (PCQN) is useful to evaluate basic knowledge about palliative care, but its adaptation into the Spanish language and the analysis of its effectiveness and utility for Spanish culture is lacking.

PURPOSE

To report the adaptation into the Spanish language and the psychometric analysis of the Palliative Care Quiz for Nurses.

METHOD

The Palliative Care Quiz for Nurses-Spanish Version (PCQN-SV) was obtained from a process including translation, back-translation, comparison with versions in other languages, revision by experts, and pilot study. Content validity and reliability of questionnaire were analyzed. Difficulty and discrimination indexes of each item were also calculated according to Item Response Theory (IRT).

FINDINGS

Adequate internal consistency was found (S-CVI = 0.83); Cronbach's alpha coefficient of 0.67 and KR-20 test result of 0,72 reflected the reliability of PCQN-SV. The questionnaire had a global difficulty index of 0,55, with six items which could be considered as difficult or very difficult, and five items with could be considered easy or very easy. The discrimination indexes of the 20 items, show us that eight items are good or very good while six items are bad to discriminate between good and bad respondents.

DISCUSSION

Although in shows internal consistency, reliability and difficulty indexes similar to those obtained by versions of PCQN in other languages, a reformulation of the items with lowest content validity or discrimination indexes and those showing difficulties with their comprehension is an aspect to take into account in order to improve the PCQN-SV.

CONCLUSION

The PCQN-SV is a useful Spanish language instrument for measuring Spanish nurses' knowledge in palliative care and it is adequate to establish international comparisons.

Non-chemotherapy drug-induced agranulocytosis in a tertiary hospital

Drug-induced agranulocytosis is a rare haematological disorder considered as severe adverse drug reaction. Due to its low incidence, the number of studies are low and the variability of clinical features and presentation in hospitalized patients is rarely described. Awe performed an observational, transversal and retrospective study in the haematology and toxicology unit in a tertiary hospital located in Spain (Valencia) (1996–2010) in order to assess its incidence, the drugs involved, the management and outcomes of drug-induced agranulocytosis. Twenty-one cases of agranulocytosis were retrieved. All of them presented severe and symptomatic agranulocytosis (fever and infection). The most common drug associated with drug-induced agranulocytosis was metamizole administration but other drugs belonging to different pharmacological classes as well (carbimazol, sulfasalazine, bisoprolol, itraconazole, amitryptiline, ketorolac and claritomicine+cefuroxime). No differences between sex and age were found in relationship with the manifestations or course of agranulocytosis. In contrast, a significantly negative association was found between age of patients and the percentage of increase in neutrophil count. Administration of human granulocyte colony-stimulating factor did not significantly enhance the recovery of the process or the restoration of leucocytes count, suggesting a limited utility in this type of agranulocytosis.
