RESUMEN

The perinatal transmission of HIV is preventable through a regimen that includes testing of all pregnant individuals, antiretroviral treatment (ART) for the pregnant individual, prophylactic or preventative ART for the infant, and cesarean section delivery for mothers with HIV viremia at the time of delivery. Under this protocol, the United States has seen a significant decline in the perinatal transmission of HIV and achieved a perinatal HIV transmission rate of 0.9% in 2019. However, despite this progress nationally and after zero transmissions in 2021, Maryland recorded 6 cases of perinatal HIV diagnoses in 2022. Each of the 3 major referral centers for pediatric HIV patients in Maryland reported 2 new cases in 2022. A root cause analysis of the cases identified risk factors including delayed entry into perinatal and HIV care, premature birth, maternal adherence challenges in the setting of substance use and other adverse social determinants of health, and failure to diagnose maternal HIV infection in a timely way. All patients were successfully linked to care and initiated on ART. Multiple factors contributed to the 2022 increase in cases of perinatal HIV in Maryland. To achieve and then sustain the elimination of perinatal HIV transmission, the constancy of systems that eliminate barriers for all pregnant people to access testing, prevention, and treatment is critical.

RESUMEN

BACKGROUND: For people with limited lifetime expectancy, the benefit of many medications may be outweighed by their potential harms. Despite the relevance of reducing unnecessary medication use, deprescribing is poorly enacted in primary care practice. AIM: This study aims to describe factors, as identified by primary care professionals and patients, that influence deprescribing in the last phase of life. DESIGN: Semi-structured interviews were conducted and analysed using a thematic approach. SETTING/PARTICIPANTS: This study was performed in primary care settings, including general practices, hospices and community care teams in The Netherlands. Purposefully identified primary care professionals (general practitioners, pharmacists, nurses) and patients with limited lifetime expectancy due to advanced chronic illness or cancer and their caretakers were interviewed. RESULTS: Three themes emerged detailing factors influencing deprescribing in the last phase of life in primary care: (1) non-maleficence, the wish to avoid additional psychological or physical distress; (2) reactive care, the lack of priority and awareness of eligible patients; and (3) discontinuity of care within primary care and between primary care and specialty care. CONCLUSIONS: Deprescribing is an incremental process, complicated by the unpredictability of life expectancy and attitudes of patients and health care professionals that associate continued medication use with clinical stability. Opportunities to facilitate the deprescribing process and its acceptance include the routinely systematic identification of patients with limited life expectancy and potentially inappropriate medications, and normalisation of deprescribing as component of regular primary care, occurring for all patients and continuing into end-of-life care.

RESUMEN

A high prevalence of mpox in men who have sex with men and in people with HIV, plus visually striking and contagious lesions, have raised concerns for mpox stigma. 24 PCR-confirmed mpox patients were surveyed over the course of three months, utilizing an mpox stigma scale adapted from the HIV Stigma Scale plus assessment of pain, analgesic efficacy, and healthcare experiences. Participants were cis-male (100%), with male sexual partners (96%), mostly African-American (88%), and living with HIV (79%). Patients answered 4-16 of 24 (mean 10) stigma questions affirmatively, particularly related to negative effects of mpox on the LGBTQ community. 79% reported pain, most commonly of limbs and perianal area, with perianal pain being rated most severe. The most effective pain relief occurred with opioids (100% major relief, n = 2) and tecovirimat (63% major relief, 25% moderate, n = 16). Patients were satisfied with care provided at the studied clinics, but had negative experiences at all other mentioned sites.

RESUMEN

BACKGROUND AND OBJECTIVE: The majority of palliative care provision occurs in general practice, yet only 9% of palliative care clinical trials were conducted in this setting. Evidence from hospital and specialist settings is not readily transferable to general practice, as the population, context and care processes are vastly different. Conducting interventional palliative care research in general practice settings is subject to many challenges and barriers. This narrative review aims to describe the factors influencing the conduct of interventional research in general practice settings for patients with palliative care needs. METHODS: A narrative review was performed to identify factors affecting the conduct of palliative care interventional studies in general practice. A literature search of MEDLINE was conducted on 26 September 2023, and data were synthesised utilising a narrative approach. KEY CONTENT AND FINDINGS: Sixteen articles were identified. Five thematic groupings were identified from the literature that affected the interventions: factors related to health care professionals (HCPs), patients and carers, general practices, health systems, and research design. HCPs and practices were focused on providing clinical care and struggled to incorporate research into their workload. Staff and patients often had negative perceptions in palliative care combined with limited research experience, often resulting in unwillingness to engage in interventions and gatekeeping. Engaging with general practice staff to design, participate and champion research were key facilitators of successful interventions. CONCLUSIONS: Palliative care interventions in general practice are invariably complex and challenging, yet acutely needed to address the care needs of patients in the community setting. Working together with patients, carers and clinicians to design and implement interventions appropriate for general practice settings is fundamental to their success.

RESUMEN

Background: Palliative care is subject to substantial variations in care, which may be shaped through adapting the organisational structures through which care is provided. Whilst the goal of these structures is to improve patient care, there is a lack of evidence regarding their effect on care processes and patient outcomes. Aims: This study aims to describe the relationship between care structures and the quantity and domains of care processes in hospice care. Design: Retrospective cohort study. Settings/Participants: Data were collected from Dutch hospice patient's clinical records and hospice surveys, detailing hospice structures, patient clinical characteristics and care processes. Results: 662 patients were included from 42 hospices, mean age 76.1 years. Hospices were categorised according to their care structures - structured clinical documentation and multidisciplinary meetings. Patients receiving care in hospices with structured multidisciplinary meetings had an increased quantity of documented care processes per patient on admission through identification (median 4 vs 3, P < .001), medication (2 vs 1, P = .004) and non-medication (1 vs 0, P < .001) interventions, monitoring (2 vs 1, P < .001) and evaluation (0 vs 0, P = .014), and prior to death. Similar increases were identified for patients who received care in hospices with structured documentation upon admission, but these changes were not consistent prior to death. Conclusions: This study details that the care structures of documentation and multidisciplinary meetings are associated with increased quantity and breadth of documentation of care processes in hospice care. Employing these existing structures may result in improvements in the documentation of patient care processes, and thus better communication around patient care.

RESUMEN

Despite significant advancements in material science, surgical site infection (SSI) rates remain high and prevention is key. This study aimed to demonstrate the in vivo safety and antibacterial efficacy of titanium implants treated with a novel broad-spectrum biocidal compound (DBG21) against methicillin-resistant Staphylococcus aureus (MRSA). Titanium (Ti) discs were covalently bound with DBG21. Untreated Ti discs were used as controls. All discs were implanted either untreated for 44 control mice or DBG21-treated for 44 treated mice. After implantation, 1 × 107 colony forming units (CFU) of MRSA were injected into the operating site. Mice were killed at 7 and 14 days to determine the number of adherent bacteria (biofilm) on implants and in the peri-implant surrounding tissues. Systemic and local toxicity were assessed. At both 7 and 14 days, DBG21-treated implants yielded a significant decrease in MRSA biofilm (3.6 median log10 CFU [99.97%] reduction [p < 0.001] and 1.9 median log10 CFU [98.7%] reduction [p = 0.037], respectively) and peri-implant surrounding tissues (2.7 median log10 CFU/g [99.8%] reduction [p < 0.001] and 5.6 median log10 CFU/g [99.9997%] reduction [p < 0.001], respectively). There were no significant differences between control and treated mice in terms of systemic and local toxicity. DBG-21 demonstrated a significant decrease in the number of biofilm bacteria without associated toxicity in a small animal implant model of SSI. Preventing biofilm formation has been recognized as a key element of preventing implant-related infections.

RESUMEN

PURPOSE: In hospital settings, patients, visitors, and staff engage in many interactions outside formal clinical encounters. Whilst many of these may be inconsequential, others contribute significantly to how patients and their carers experience cancer and its treatment. This article aims to explore the experiences and significance of interactions that occur outside formal clinical encounters in hospital cancer treatment settings. METHODS: Semi-structured interviews were conducted with cancer patients, carers, and staff recruited from two hospital sites and cancer support groups. Hermeneutic phenomenology informed lines of questioning and data analysis. RESULTS: Thirty-one people participated in the study: 18 cancer patients, four carers, and nine staff members. The experiences of informal interactions were grouped into three themes: connecting, making sense, and enacting care. The participants described how these encounters allowed connection with others in the hospital spaces, facilitating a sense of belonging, normality, and self-worth. Through these interactions, individuals participated in making sense of their experiences, to better anticipate the decisions and challenges that might lie ahead. By connecting with other individuals, they cared for others and felt cared for themselves, and were able to learn from, teach, and support each other. CONCLUSIONS: Outside the confines of the clinical discourses participants negotiate terms of engagement, sharing of information, expertise, and their own personal stories that they may employ to contribute to the individuals around them. These interactions occur within a loose and evolving framework of social interactions, an 'informal community', in which cancer patients, carers, and staff members play active and meaningful roles.

RESUMEN

BACKGROUND: Several preventive medications and supplements become inappropriate in the last phase of life due to increased risk of adverse events caused by changed pharmacokinetics, drug-drug interactions, and changed care goals. Information on these preventive medication and supplements use in patients with a life-limiting illness in the home-care setting is limited. The primary aim of this study was to assess the use of four different groups of preventive drugs and supplements, which are inappropriate in adult patients with a life-limiting illness, living at home in the last year of life. The secondary aims were to assess reasons for discontinuing these drugs as documented in the general practitioners' patient file and whether these reasons affected the time between medication discontinuation and death. METHODS: We performed a retrospective cohort study using the routine primary care database of the Julius General Practitioners' Network of the University Medical Centre Utrecht, a database consisting of routine care data from GPs from the city of Utrecht and its vicinity. Patients in the homecare setting with a life-limiting illness, diagnosed at least one year before death, were included. Descriptive analyses were used to describe the study population and the frequency of starting, using, and discontinuing medication and supplements in the last year of life. RESULTS: A total of 458 of 666 included patients (69%) used at least one preventive drug in the last year of life. Vitamins were used by 36% of the patients, followed with 35% using cholesterol-lowering medication, 24% using calcium supplements and 9% using bisphosphonates. Bisphosphonates were discontinued by 70% of the users, calcium supplements by 61%, vitamins by 56% and cholesterol-lowering medication by 48% of the users, with a median interval between day of discontinuation and death of 119, 60, 110 and, 65 days, respectively. The median time between medication or supplement discontinuation and death was longest in patients with side effects and who had medication reviews. CONCLUSION: Many patients in their last phase of life in the home-care setting use inappropriate medication and supplements. Timely medication review may contribute to optimise medication use in the last year of life.

RESUMEN

Advanced imaging techniques are needed to assist in providing a prognosis for patients with traumatic brain injury (TBI), particularly mild TBI (mTBI). Diffusion tensor imaging (DTI) is one promising advanced imaging technique, but has shown variable results in patients with TBI and is not without limitations, especially when considering individual patients. Efforts to resolve these limitations are being explored and include developing advanced diffusion techniques, creating a normative database, improving study design, and testing machine learning algorithms. This article will review the fundamentals of DTI, providing an overview of the current state of its utility in evaluating and providing prognosis in patients with TBI.

RESUMEN

The Coronavirus disease 2019 (COVID-19) outbreak impacted health care. We investigated its impact on the time to referral and diagnosis for symptomatic cancer patients in The Netherlands. We performed a national retrospective cohort study utilizing primary care records linked to The Netherlands Cancer Registry. For patients with symptomatic colorectal, lung, breast, or melanoma cancer, we manually explored free and coded texts to determine the durations of the primary care (IPC) and secondary care (ISC) diagnostic intervals during the first COVID-19 wave and pre-COVID-19. We found that the median IPC duration increased for colorectal cancer from 5 days (Interquartile Range (IQR) 1-29 days) pre-COVID-19 to 44 days (IQR 6-230, p < 0.01) during the first COVID-19 wave, and for lung cancer, the duration increased from 15 days (IQR) 3-47) to 41 days (IQR 7-102, p < 0.01). For breast cancer and melanoma, the change in IPC duration was negligible. The median ISC duration only increased for breast cancer, from 3 (IQR 2-7) to 6 days (IQR 3-9, p < 0.01). For colorectal cancer, lung cancer, and melanoma, the median ISC durations were 17.5 (IQR (9-52), 18 (IQR 7-40), and 9 (IQR 3-44) days, respectively, similar to pre-COVID-19 results. In conclusion, for colorectal and lung cancer, the time to primary care referral was substantially prolonged during the first COVID-19 wave. In such crises, targeted primary care support is needed to maintain effective cancer diagnosis.

RESUMEN

BACKGROUND: Many patients with suspected appendicitis are initially evaluated at outlying hospitals and then transferred to a tertiary care pediatric hospital for surgical management. We sought to evaluate whether diagnosis prior to transfer provides a reliable basis for direct admission to a pediatric surgery service. METHODS: Patients transferred during calendar year 2018 with the principal diagnosis of acute appendicitis were compared based on the service accepting the patient: Emergency Department (ED) or Pediatric Surgery (PS). Data were evaluated using Student's t-tests. RESULTS: Overall patient characteristics were consistent among ED and PS transfers. The number of patients accepted directly to PS underwent significantly more computed tomography (80.2% vs 54.1%, P = .0002). Despite diagnostic "confirmation" with cross-sectional imaging, 14.7% of patients admitted directly to PS were found to be false positives. CONCLUSION: A significant proportion of patients referred to pediatric hospitals for appendicitis do not require admission or operation. A protocol which encourages cross-sectional imaging before PS evaluation may subject children to unnecessary radiation and still result in non-surgical admissions. Routine ED transfer allows PS evaluation, targeted imaging, and discharge for non-surgical patients. This approach decreases costs for the families whose children received a false positive diagnosis at a referring facility, while preserving inpatient bed availability.

RESUMEN

Background: National clinical guidelines have been developed internationally to reduce variations in clinical practices and promote the quality of palliative care. In The Netherlands, there is considerable variability in the organisation and care processes of inpatient palliative care, with three types of hospices - Volunteer-Driven Hospices (VDH), Stand-Alone Hospices (SAH), and nursing home Hospice Units (HU). Aim: This study aims to examine clinical practices in palliative care through different hospice types and identify variations in care. Methods: Retrospective cohort study utilising clinical documentation review, including patients who received inpatient palliative care at 51 different hospices and died in 2017 or 2018. Care provision for each patient for the management of pain, delirium and palliative sedation were analysed according to the Dutch national guidelines. Results: 412 patients were included: 112 patients who received treatment for pain, 53 for delirium, and 116 patients underwent palliative sedation therapy. Care was provided in accordance with guidelines for pain in 32%, 61% and 47% (P = .047), delirium in 29%, 78% and 79% (P = .0016), and palliative sedation in 35%, 63% and 42% (P = .067) of patients who received care in VDHs, SAHs and HUs respectively. When all clinical practices were considered, patient care was conducted according to the guidelines for 33% of patients in VDHs, 65% in SAHs, and 50% in HUs (P < .001). Conclusions: The data demonstrate that care practices are not standardised throughout Dutch hospices and exhibit significant variations between type of hospice.

RESUMEN

Introduction: In the Netherlands, the onset of the coronavirus pandemic saw shifts in primary health service provision away from physical consultations, cancer-screening programs were temporarily halted, and government messaging focused on remaining at home. In March and April 2020, weekly cancer diagnoses decreased to 73% of their pre-COVID levels, and 39% for skin cancer. This study aims to explore the effect of the COVID pandemic on patient presentations for cancer-related symptoms in primary care in The Netherlands. Methods: Retrospective cohort study using routine clinical primary care data. Monthly incidences of patient presentations for cancer-related symptoms in five clinical databases in The Netherlands were analysed from March 2018 to February 2021. Results: Data demonstrated reductions in the incidence of cancer-related symptom presentations to primary care during the first COVID wave (March-June 2020) of -34% (95% CI: -43 to -23%) for all symptoms combined. In the second wave (October 2020-February 2021) there was no change in incidence observed (-8%, 95% CI -20% to 6%). Alarm-symptoms demonstrated decreases in incidence in the first wave with subsequent incidences that continued to rise in the second wave, such as: first wave: breast lump -17% (95% CI: -27 to -6%) and haematuria -15% (95% CI -24% to -6%); and second wave: rectal bleeding +14% (95% CI: 0 to 30%) and breast lump +14% (95% CI: 2 to 27%). Presentations of common non-alarm symptom such as tiredness and naevus demonstrated decreased in-cidences in the first wave of 45% (95% CI: -55% to -33%) and 37% (95% CI -47% to -25%). In the second wave, tiredness incidence was reduced by 20% (95% CI: -33% to -3%). Subgroup analy-sis did not demonstrate difference in incidence according to sex, age groups, comorbidity status, or previous history of cancer. Conclusions: These data describe large-scale primary care avoidance that did not increase until the end of the first COVID year for many cancer-related symptoms, suggestive that substantial numbers of patients delayed presenting to primary care. For those patients who had underlying cancer, this may have had impacted the cancer stage at diagnosis, treatment, and mortality.

RESUMEN

OBJECTIVES: Hospice care in the Netherlands is provided in three different types of hospice facilities: volunteer-driven hospices (VDH), stand-alone hospices (SAHs) and hospice unit nursing homes (HU). The organisational structures range from care directed by trained volunteers in VDH to care provided by multiprofessional teams in SAH and HU units.This study aims to characterise the patient populations who access Dutch hospices and describe the patient profiles in different hospice types. METHODS: A retrospective cohort study using clinical records of adult hospice inpatients in 2017-2018 from a random national sample of hospices. RESULTS: In total 803 patients were included from 51 hospices, mean age 76.1 (SD 12.4). 78% of patients had a primary diagnosis of cancer, 3% identified as non-Dutch cultural background and 17% were disorientated on admission. At admission, all patients were perceived to have physical needs. Psychological needs were reported in 37%, 36% and 34%, social needs by 53%, 52% and 62%, and existential needs by 23%, 30% and 18% of patients in VDH, SAH, HU units, respectively. 24%, 29% and 27% of patients from VDHs, SAHs and HUs had care needs in three dimensions, and 4%, 6% and 3% in all four dimensions. CONCLUSIONS: People who access Dutch hospices predominantly have cancer, and have a range of physical, psychological, social and existential needs, without substantial differences between hospice types. Patients with non-malignant disease and non-Dutch cultural backgrounds are less likely to access hospice care, and future policy would ideally focus on facilitating their involvement.

RESUMEN

Purpose of Review: Severe Acute Respiratory Syndrome-Coronavirus-2 (SARS-CoV-2) can increase the susceptibility of individuals to contracting mucormycosis through several mechanisms. Nowadays, coronavirus disease (COVID-19)-associated mucormycosis (CAM) is a serious public health concern, particularly in developing countries. This meta-analysis aims to identify the risk factors that affect the mortality rate of patients with CAM. Recent Findings: We systematically searched PubMed, Google Scholar, Scopus, Cochrane library, and preprint databases using pertinent keywords and the reference lists of the included relevant articles from inception till October 27, 2021. In order to reduce the effects of small-scale studies, we only selected cross-sectional, case-control, and cohort studies and case series with at least four patients. We identified 26 articles that included 821 patients with CAM. The effect size (ES) of mortality rate was 28% (95% confidence interval (CI) 20%-38%; I2 =82.28%; p for Cochran Q<0.001). The CAM patients with a history of comorbidities other than diabetes (malignancies, transplant, or renal failure), mechanical ventilation due to COVID-19, pulmonary and cerebral mucormycosis, and those who only received medical treatment for mucormycosis had the highest mortality rate. Summary: Coronavirus disease (COVID-19)-associated mucormycosis (CAM) is a major public health problem, particularly in developing countries. Severe COVID-19 infection, history of mechanical ventilation, early CAM, comorbidities other than diabetes (malignancies, transplant, or renal failure), pulmonary and rhino-orbito-cerebral mucormycosis, and delivering only medical treatment for mucormycosis were the worst prognostic factors in CAM patients. Identifying the mortality-related risk factors in CAM patients may help reduce the mortality rate by implementing optimized treatment approaches.

RESUMEN

BACKGROUND: Identified DNA variants associated with serum 25-hydroxyvitamin vitamin D (25[OH]D) concentration may provide mechanistic insights into the vitamin D metabolic pathway in individuals. Our aim was to further characterise participants and their serum 25(OH)D concentration at baseline using candidate single nucleotide polymorphism (SNP) genotyping. METHODS: 5110 participants, aged 50-84 years, were recruited from the community. Blood samples were collected at baseline to measure serum 25(OH)D by liquid chromatography mass spectrometry and the participants were genotyped for four markers close to or within genes in the vitamin D metabolic pathway known to be associated with differences in 25(OH)D. The markers and their associated genes were rs12785878 (DHCR7), rs10741657 (CYP2R1), rs4588 (DBP) and rs2228570 (VDR). RESULTS: All four markers had significantly different genotype distributions and minor allele frequencies between the four self-determined ethnicities (European/Other, Maori, Pacific, and South Asian). For example, the frequency in each ethnic group of the G allele for the marker rs12785878 was 0.26, 0.71, 0.89, and 0.78 respectively. Using multivariable regression in the full cohort, three out of four markers were significantly associated with baseline concentrations of 25(OH)D (mean differences: 2.9-10.9 nmol/L). Collectively, the four markers explained 8.4% of the variation in 25(OH)D concentrations. CONCLUSION: Significant ethnic variations exist in the distribution of alleles associated with serum 25(OH)D concentration, particularly rs12785878, in a multi-ethnic community sample from New Zealand.

RESUMEN

Rapid, cost-effective identification of genetic variants in small candidate genomic regions remains a challenge, particularly for less well equipped or lower throughput laboratories. The application of Oxford Nanopore Technologies' MinION sequencer has the potential to fulfil this requirement. We demonstrate a proof of concept for a multiplexing assay that pools PCR amplicons for MinION sequencing to enable sequencing of multiple templates from multiple individuals, which could be applied to gene-targeted diagnostics. A combined strategy of barcoding and sample pooling was developed for simultaneous multiplex MinION sequencing of 100 PCR amplicons. The amplicons are family-specific, spanning a total of 30 loci in DNA isolated from 82 human neurodevelopmental cases and family members. The target regions were chosen for further interrogation because a potentially disease-causative variant had been identified in affected individuals following Illumina exome sequencing. The pooled MinION sequences were deconvoluted by aligning to custom references using the minimap2 aligner software. Our multiplexing approach produced an interpretable and expected sequence from 29 of the 30 targeted genetic loci. The sequence variant which was not correctly resolved in the MinION sequence was adjacent to a five nucleotide homopolymer. It is already known that homopolymers present a resolution problem with the MinION approach. Interestingly despite equimolar quantities of PCR amplicon pooled for sequencing, significant variation in the depth of coverage (127×-19,626×; mean = 8321×, std err = 452.99) was observed. We observed independent relationships between depth of coverage and target length, and depth of coverage and GC content. These relationships demonstrate biases of the MinION sequencer for longer templates and those with lower GC content. We demonstrate an efficient approach for variant discovery or confirmation from short DNA templates using the MinION sequencing device. With less than 130 × depth of coverage required for accurate genotyping, the methodology described here allows for rapid highly multiplexed targeted sequencing of large numbers of samples in a minimally equipped laboratory with a potential cost as much 200 × less than that from Sanger sequencing.

RESUMEN

BACKGROUND: Dematiaceous fungi cause a number of infectious syndromes referred to as phaeohyphomycosis among both immunocompetent and immunocompromised hosts. We performed a systematic review to characterize these infections in solid organ transplant recipients (SOTR). METHODS: We searched PubMed database (last searched 1/6/2022) for English-language reports on dematiaceous fungal infections in SOTR. Included reports needed individualized demographic, treatment, and outcome data; pediatric reports were excluded. A universally applicable bias assessment was performed on reports. Models for infection type and outcome were created using the Bayesian paradigm. RESULTS: We included 149 reports on 201 cases of dematiaceous fungal infections in SOTR. The mean age was 54 years, 72% were men, and kidney recipients accounted for 61% of cases. Skin and soft tissue infection (SSTI) was the most common infectious syndrome (73%). Death from infection occurred in 7% of cases (14/201), with disseminated (32%) cases having the highest mortality. Our model for infection type predicted the relative probability of central nervous system infection to be highest in liver recipients. Across all transplant types, higher relative probabilities of disseminated and pulmonary infections occur in the early post-transplant period, and the predicted probabilities for these infection types decreased after 100 months post-transplantation. DISCUSSION: We identified SSTI as the most common dematiaceous fungal infections in SOTR. Disseminated infections carried the worst prognosis. The evidence in this review is limited by the heterogeneity of included cases. No funding source was used, and this review's protocol was not registered.

RESUMEN

Background: Splenic abscess is a rare infection often resulting from hematogenous spread. Immunocompromised states are commonly comorbid, and the microbiology is heterogeneous. Methods: We conducted a retrospective review of 33 cases identified by convenience sampling. Cases were treated in our institution's hospital system between May 2012 and February 2021 and classified as proven or probable based on predetermined criteria. Results: The median age was 57 years, and 58% were men. Common underlying diseases included diabetes mellitus (30%), pancreatic disease (30%), and hematological malignancy (15%). The most common mechanism of pathogenesis was hematogenous spread (n = 13). Escherichia coli, enterococcal spp., and anaerobes were frequently implicated. One case was discovered at autopsy and excluded from subsequent analyses. The median duration of antimicrobial therapy (range) was 45 (5-525) days, and the median length of index hospitalization was 20 days. Percutaneous drainage by interventional radiology was common (17 of 32; 53%), and 6 patients underwent splenectomy. Treatment success was achieved in 14 of 32 cases (44%), with clinical stability in 3 of 32 cases (9%). Failures occurred in 13 of 32 (41%) cases, 2 of whom died from splenic abscesses. Two patients (2 of 32) were lost to follow-up. Conclusions: To our knowledge, this is the largest North American series since the turn of the century and the first to distinguish between proven and probable cases. As reflected in our series, patients with splenic abscess may require prolonged hospitalizations and courses of antimicrobial therapy. Improvements in management are needed.
