Successful Use of Propofol After Failed Palliative Sedation in Patients With Refractory Symptoms.

Context: Propofol is a general anesthetic used in multiple clinical scenarios. Despite growing evidence supporting its use in palliative care, propofol is rarely used in palliative sedation. Reluctance toward the adoption of propofol as a sedative agent is often associated with fear of adverse events such as respiratory arrest. Objectives: We aimed to describe efficacy and safety of palliative sedation in refractory sedation with propofol using a protocol based on low, incremental dosing. Methods: A retrospective observational study featuring inpatients receiving sedative treatment with propofol in our palliative care unit in Madrid (Spain) between March 1, 2018 and February 28, 2023, following a newly developed protocol. Results: During the study period, 22 patients underwent sedation with propofol. Propofol was used successfully to control different refractory symptoms, mainly psychoexistential suffering and delirium. All patients had undergone previous failed attempts at sedation with other medications (midazolam or lemovepromazine) and presented risk factors for complicated sedation. All patients achieved satisfactory (profound) levels of sedation measured with the Ramsay Sedation Scale, but total doses varied greatly between patients. Most patients (17, 77%) received combined therapy with propofol and other sedative medications to harness synergies. The median time between start of sedation with propofol and death was 26.0 hours. No cases of apnea or death during induction were recorded. Conclusion: A protocol for palliative sedation with propofol based on low, incremental dosing, with the option of administering an initial induction bolus, shows excellent results regarding adequate levels of sedation, without observing apnea or respiratory depression. Our results promote the use of propofol to achieve palliative sedation in patients with refractory symptoms and risk factors for complicated sedation at the end of life.

Risk Factors for Therapeutic Failure and One-Year Mortality in Patients with Intramedullary Nail-Associated Infection after Trochanteric and Subtrochanteric Hip Fracture Repair.

Despite the implications of trochanteric and subtrochanteric intramedullary (IM) nail infection for patients with hip fracture, little is known about risk factors for therapeutic failure and mortality in this population. We performed a retrospective observational analysis including patients diagnosed with trochanteric and subtrochanteric IM nail infection at a Spanish academic hospital during a 10-year period, with a minimum follow-up of 22 months. Of 4044 trochanteric and subtrochanteric IM nail implants, we identified 35 cases of infection during the study period (0.87%), 17 of which were chronic infections. Patients with therapeutic failure (n = 10) presented a higher average Charlson Comorbidity Index (CCI) (5.40 vs. 4.21, p 0.015, CI 0.26-2.13) and higher rates of polymicrobial (OR 5.70, p 0.033, CI 1.14-28.33) and multidrug-resistant (OR 7.00, p 0.027, CI 1.24-39.57) infections. Upon multivariate analysis, polymicrobial infection and the presence of multidrug-resistant pathogens were identified as independent risk factors for therapeutic failure. Implant retention was associated with an increased risk of failure in chronic infection and was found to be an independent risk factor for overall one-year mortality in the multivariate analysis. Our study highlights the importance of broad-spectrum empirical antibiotics as initial treatment of trochanteric and subtrochanteric IM nail-associated infection while awaiting microbiological results. It also provides initial evidence for the importance of implant removal in chronic IM-nail infection.

Effect of an algorithm for automatic placing of standardised test order sets on low-value appointments and attendance rates at four Spanish teaching hospitals: an interrupted time series analysis.

OBJECTIVE: Reducing backlogs for elective care is a priority for healthcare systems. We conducted an interrupted time series analysis demonstrating the effect of an algorithm for placing automatic test order sets prior to first specialist appointment on avoidable follow-up appointments and attendance rates. DESIGN: Interrupted time series analysis. SETTING: 4 academic hospitals from Madrid, Spain. PARTICIPANTS: Patients referred from primary care attending 10 033 470 outpatient appointments from 16 clinical specialties during a 6-year period (1 January 2018 to 30 June 2023). INTERVENTION: An algorithm using natural language processing was launched in May 2021. Test order sets developed for 257 presenting complaints from 16 clinical specialties were placed automatically before first specialist appointments to increase rates of diagnosis and initiation of treatment with discharge back to primary care. PRIMARY AND SECONDARY OUTCOME MEASURES: Primary outcomes included rate of diagnosis and discharge to primary care and follow-up to first appointment index. The secondary outcome was trend in 'did not attend' rates. RESULTS: Since May 2021, a total of 1 175 814 automatic test orders have been placed. Significant changes in trend of diagnosis and discharge to primary care at first appointment (p=0.005, 95% CI 0.5 to 2.9) and 'did not attend' rates (p=0.006, 95% CI -0.1 to -0.8) and an estimated attributable reduction of 11 306 avoidable follow-up appointments per month were observed. CONCLUSION: An algorithm for placing automatic standardised test order sets can reduce low-value follow-up appointments by allowing specialists to confirm diagnoses and initiate treatment at first appointment, also leading to early discharge to primary care and a reduction in 'did not attend' rates. This initiative points to an improved process for outpatient diagnosis and treatment, delivering healthcare more effectively and efficiently.

The caregiver's perspective on end-of-life inpatient palliative care: a qualitative study.

INTRODUCTION: Understanding patient and caregiver experience is key to providing person-centered care. The palliative care approach includes holistic assessment and whole-person care at the end of life, that also involves the patient's family and loved ones. The aim of this study was to describe the way that family caregivers experienced patients' deaths during their loved ones' last hospital admission, comparing inpatient palliative care (PCU) and non-palliative care (Non-PCU) units. METHODS: A qualitative case study approach was implemented. Family caregivers of terminally ill patients admitted to the Infanta Elena Hospital (Madrid, Spain) between 2016 and 2018 were included using purposeful sampling. Eligible caregivers were first-degree relatives or spouses present during the patient's last hospital admission. Data were collected via in-depth interviews and researchers' field notes. Semi-structured interviews with a question guide were used. A thematic inductive analysis was performed. The group of caregivers of patients admitted to the PCU unit and the group of caregivers of patients admitted to Non-PCU were analyzed separately, through a matrix. RESULTS: In total 24 caregivers (12 from the PCU and 12 from Non-PCU units) were included. Two main themes were identified: caregivers' perception of scientific and technical appropriateness of care, and perception of person-centred care. Scientific appropriateness of care was subdivided into two categories: diagnostic tests and treatment, and symptom control. Perception of person-centred care was subdivided as: communication, emotional support, and facilitating the farewell process. Caregivers of patients admitted to a PCU unit described their experience of end-of-life care as positive, while their Non-PCU unit counterparts described largely negative experiences. CONCLUSIONS: PCU provides a person-centered approach to care at the end of life, optimizing treatment for patients with advanced disease, ensuring effective communication, establishing a satisfactory professional relationship with both patients and their loved ones, and facilitating the farewell process for family caregivers.

This article describes a qualitative case study focusing on family caregivers' perception of end-of-life care during their loved ones' dying process in their last hospital admission. Differences were observed between palliative care and non-palliative care groups regarding the perception of scientific appropriateness of care and person-centered nature of care as reported by caregivers.

Using artificial intelligence to reduce orthopedic surgical site infection surveillance workload: Algorithm design, validation, and implementation in 4 Spanish hospitals.

BACKGROUND: Surgical site infection (SSI) surveillance is a labor-intensive endeavor. We present the design and validation of an algorithm for SSI detection after hip replacement surgery, and a report of its successful implementation in 4 public hospitals in Madrid, Spain. METHODS: We designed a multivariable algorithm, AI-HPRO, using natural language processing (NLP) and extreme gradient boosting to screen for SSI in patients undergoing hip replacement surgery. The development and validation cohorts included data from 19,661 health care episodes from 4 hospitals in Madrid, Spain. RESULTS: Positive microbiological cultures, the text variable "infection", and prescription of clindamycin were strong markers of SSI. Statistical analysis of the final model indicated high sensitivity (99.18%) and specificity (91.01%) with an F1-score of 0.32, AUC of 0.989, accuracy of 91.27%, and negative predictive value of 99.98%. DISCUSSION: Implementation of the AI-HPRO algorithm reduced the surveillance time from 975 person/hours to 63.5 person/hours and permitted an 88.95% reduction in the total volume of clinical records to be reviewed manually. The model presents a higher negative predictive value (99.98%) than algorithms relying on NLP alone (94%) or NLP and logistic regression (97%). CONCLUSIONS: This is the first report of an algorithm combining NLP and extreme gradient-boosting to permit accurate, real-time orthopedic SSI surveillance.

SDQ Dysregulation Profile and Its Relation to the Severity of Psychopathology and Psychosocial Functioning in a Sample of Children and Adolescents With ADHD.

Objective: A substantial number of children and adolescents with ADHD show severe affective and behavioral dysregulation. A dysregulation profile (DP) distinguishes those participants at a higher risk of comorbidity, dysfunction, and a poorer response to treatment. It was identified as high scoring in certain subscales of the Strengths and Difficulties Questionnaire (SDQ-DP). We developed a cross-sectional study to assess the clinical utility of the SDQ-DP in ADHD. Method: Two hundred fifty clinic-referred children and adolescents with ADHD were assessed. Univariate and linear regression analyses were performed to compare those participants with high levels of SDQ-DP with those with low levels, as well as to examine the association between the SDQ-DP and clinical variables. Results: In all, 28% of ADHD participants had high levels of SDQ-DP. These participants showed higher functional impairment and clinical severity. Conclusion: The use of the SDQ-DP will enable identification of those ADHD patients at greater risk.

Pharmacotherapy options and drug development in managing periprosthetic joint infections in the elderly.

INTRODUCTION: Prosthetic joint infections are an increasingly important problem among patients undergoing arthroplasty procedures, and are associated with significant morbidity, reduced quality of life, substantial healthcare costs, and even mortality. Arthroplasties are performed with increasing frequency in elderly patients, who present specific problems. AREAS COVERED: Surgical therapy is clearly influenced by the clinical status of the patient, which in some case can contraindicate surgery. Antibiotic selection is also affected by comorbidities and underlying diseases, which in some cases reduce therapeutic options. The authors review this together with the changes in pharmacokinetics and pharmacodynamics in the elderly population and the prospects for future research on prevention and treatment. EXPERT OPINION: The management of PJI in the elderly makes multidisciplinary teams even more mandatory than in other patients, because the complexity of these patients. A frequent scenario is that in which surgery is contraindicated with long-term suppressive treatment as the only available option. Treating physicians must consider the presence of multiple comorbidities, interactions with other treatments and secondary effects when choosing antibiotic treatment. An in-depth knowledge of the alterations in pharmacokinetics and pharmacodynamics in elderly patients is key for a proper treatment selection.

Orthopedic Implant-Associated Infection by Multidrug Resistant Enterobacteriaceae.

INTRODUCTION: Orthopedic implant-associated infections caused by multidrug-resistant Enterobacteriaceae are a growing challenge for healthcare providers due to their increasing incidence and the difficulties of medical and surgical treatment. MATERIAL AND METHODS: A retrospective observational study of all cases of multidrug resistant Enterobacteriaceae orthopedic implant-associated infection diagnosed in a tertiary European hospital from December 2011 to November 2017 was carried out. Clinical records were reviewed using a previously designed protocol. Data analysis was performed with IBM® SPSS®, version 22. RESULTS: 25 patients met inclusion criteria. The infected implants included 10 prosthetic joints, seven osteosyntheses, six combinations of prosthetic joint and osteosynthesis material, and two spacers. Of the multidrug resistant Enterobacteriaceae obtained on culture, 12 were extended-spectrum beta-lactamase-producing Escherichia coli, three OXA-48-producing Klebsiella pneumoniae, nine extended-spectrum beta-lactamase-producing Klebsiella pneumoniae, and one extended-spectrum beta-lactamase-producing Proteus mirabilis. Combination antimicrobial therapy was employed in all cases but two. Overall, 16 (64%) patients underwent implant removal. The rate of infection control in the overall implant removal group was 100% compared to 33% in the implant retention group. A strong relationship between implant removal and infection control was observed (p = 0.001). DISCUSSION: Implant removal is strongly associated with infection control. However, in some cases, patient age and comorbidity contraindicate hardware extraction. Potential objectives for future studies should be geared towards targeting the population in which debridement, antibiotic therapy, and implant retention can be used as a first-line therapeutic strategy with a reasonable probability of achieving infection control.

The Strengths and Difficulties Questionnaire -Dysregulation Profile, Non-Suicidal Self-Injury Behaviors and the Mediating Role of Stressful Life Events.

Non-suicidal self-injury (NSSI) behaviors are self-injurious behaviors inflicted without intending death. Literature has shown the relationship between stressful life events (SLE) and NSSI behaviors. The Strengths and Difficulties Questionnaire-Dysregulation Profile (SDQ-DP) is defined as an index of self-regulatory problems, related to higher risk for suicidal ideation and attempts in adolescents. In this study the relationship between SDQ-DP and NSSI behaviors, mediated by SLE in a clinical sample of children and adolescents is analyzed. A cross-sectional study was conducted on 239 subjects (aged from 11 to 17) to test the mediation model. SDQ-DP significantly correlates with NSSI behaviors (Wald = 6.5477, p = .0105); SDQ-DP significantly correlates with SLE (T = 5.7229, p < .001); SLE significantly correlates NSSI behaviors, and the relation remains significant whilst controlling for SDQ-DP (Wald = 4.1715, p = .041); the relation between SDQ-DP and NSSI behaviors stops being significant whilst controlling for the potential mediator (SLE) (Wald = 2.9951, p = .0835). Study of indirect effect supports the mediation model (.0585 CI [.0016, .1266]). Findings are compatible with the complete mediation scenario. These results point out the importance of self-regulatory problems in coping strategies with regards to SLE and the development of NSSI behaviors.

User profiles of an electronic mental health tool for ecological momentary assessment: MEmind.

Ecological momentary assessment (EMA) is gaining importance in psychiatry. This article assesses the characteristics of patients who used a new electronic EMA tool: the MEmind Wellness Tracker. Over one year, 13811 adult outpatients in our Psychiatry Department were asked to use MEmind. We collected information about socio-demographic data, psychiatric diagnoses, illness severity, stressful life events and suicidal thoughts/behavior. We compared active users (N = 2838) and non-active users (N = 10,973) of MEmind and performed a Random Forest analysis to assess which variables could predict its use. Univariate analyses revealed that MEmind-users were younger (42.2 ± 13.5 years versus 48.5 ± 16.3 years; χ2  = 18.85; P < 0.001) and more frequently diagnosed with anxiety related disorders (57.9% versus 46.7%; χ2  = 105.92; P = 0.000) than non-active users. They were more likely to report thoughts about death and suicide (up to 24% of active users expressed wish for death) and had experienced more stressful life events than non-active users (57% versus 48.5%; χ2  = 64.65; P < 0.001). In the Random Forest analysis, 31 variables showed mean decrease accuracy values higher than zero with a 95% confidence interval (CI), including sex, age, suicidal thoughts, life threatening events and several diagnoses. In the light of these results, strategies to improve EMA and e-Mental Health adherence are discussed.
