Updates on Coding in Dermatology.

Correct coding is an important component of effective dermatology practice management. Over the past several years there have been updates to many commonly used codes within dermatology. This review highlights many of these updates, such as: The skin biopsy codes have been subdivided to reflect the different biopsy techniques. The definition of complex linear repairs has been updated and clarified. Outpatient and inpatient evaluation and management visits have new coding guidelines to determine level of care. Dermatopathology consultation codes have been updated and Category III codes related to digital pathology have been created. Understanding the details and nuances of each of these categories of codes is vital to ensuring appropriate coding is performed.

Changes in diagnostic patterns and resource utilisation in Swiss adult ICUs during the first two COVID-19 waves: an exploratory study.

BACKGROUND AND AIM: The coronavirus disease 2019 (COVID-19) outbreak deeply affected intensive care units (ICUs). We aimed to explore the main changes in the distribution and characteristics of Swiss ICU patients during the first two COVID-19 waves and to relate these figures with those of the preceding two years. METHODS: Using the national ICU registry, we conducted an exploratory study to assess the number of ICU admissions in Switzerland and their changes over time, characteristics of the admissions, the length of stay (LOS) and its trend over time, ICU mortality and changes in therapeutic nursing workload and hospital resources in 2020 and compare them with the average figures in 2018 and 2019. RESULTS: After analysing 242,935 patient records from all 84 certified Swiss ICUs, we found a significant decrease in admissions (-9.6%, corresponding to -8005 patients) in 2020 compared to 2018/2019, with an increase in the proportion of men admitted (61.3% vs 59.6%; p <0.001). This reduction occurred in all Swiss regions except Ticino. Planned admissions decreased from 25,020 to 22,021 in 2020 and mainly affected the neurological/neurosurgical (-14.9%), gastrointestinal (-13.9%) and cardiovascular (-9.3%) pathologies. Unplanned admissions due to respiratory diagnoses increased by 1971 (+25.2%), and those of patients with acute respiratory distress syndrome (ARDS) requiring isolation reached 9973 (+109.9%). The LOS increased by 20.8% from 2.55 ± 4.92 days (median 1.05) in 2018/2019 to 3.08 ± 5.87 days (median 1.11 days; p <0.001), resulting in an additional 19,753 inpatient days. The nine equivalents of nursing manpower use score (NEMS) of the first nursing shift (21.6 ± 9.0 vs 20.8 ± 9.4; p <0.001), the total NEMS per patient (251.0 ± 526.8 vs 198.9 ± 413.8; p <0.01) and mortality (5.7% vs 4.7%; p <0.001) increased in 2020. The number of ICU beds increased from 979 to 1012 (+3.4%), as did the number of beds equipped with mechanical ventilators (from 773 to 821; +6.2%). CONCLUSIONS: Based on a comprehensive national data set, our report describes the profound changes triggered by COVID-19 over one year in Swiss ICUs. We observed an overall decrease in admissions and a shift in admission types, with fewer planned hospitalisations, suggesting the loss of approximately 3000 elective interventions. We found a substantial increase in unplanned admissions due to respiratory diagnoses, a doubling of ARDS cases requiring isolation, an increase in ICU LOS associated with substantial nationwide growth in ICU days, an augmented need for life-sustaining therapies and specific therapeutic resources and worse outcomes.

Temporal trends in mortality and provision of intensive care in younger women and men with acute myocardial infarction or stroke.

BACKGROUND: Timely management of acute myocardial infarction (AMI) and acute stroke has undergone impressive progress during the last decade. However, it is currently unknown whether both sexes have profited equally from improved strategies. We sought to analyze sex-specific temporal trends in intensive care unit (ICU) admission and mortality in younger patients presenting with AMI or stroke in Switzerland. METHODS: Retrospective analysis of temporal trends in 16,954 younger patients aged 18 to ≤ 52 years with AMI or acute stroke admitted to Swiss ICUs between 01/2008 and 12/2019. RESULTS: Over a period of 12 years, ICU admissions for AMI decreased more in women than in men (- 6.4% in women versus - 4.5% in men, p < 0.001), while ICU mortality for AMI significantly increased in women (OR 1.2 [1.10-1.30], p = 0.032), but remained unchanged in men (OR 0.99 [0.94-1.03], p = 0.71). In stroke patients, ICU admission rates increased between 3.6 and 4.1% per year in both sexes, while ICU mortality tended to decrease only in women (OR 0.91 [0.85-0.95, p = 0.057], but remained essentially unaltered in men (OR 0.99 [0.94-1.03], p = 0.75). Interventions aimed at restoring tissue perfusion were more often performed in men with AMI, while no sex difference was noted in neurovascular interventions. CONCLUSION: Sex and gender disparities in disease management and outcomes persist in the era of modern interventional neurology and cardiology with opposite trends observed in younger stroke and AMI patients admitted to intensive care. Although our study has several limitations, our data suggest that management and selection criteria for ICU admission, particularly in younger women with AMI, should be carefully reassessed.

A dermatologic assessment of 101 mpox (monkeypox) cases from 13 countries during the 2022 outbreak: Skin lesion morphology, clinical course, and scarring.

BACKGROUND: In the 2022 mpox (monkeypox) outbreak, 79,000 global cases have been reported. Yet, limited dermatologic data have been published regarding lesion morphology and progression. OBJECTIVE: The objective of this study was to characterize skin lesion morphology, symptomatology, and outcomes of mpox infection over time. METHODS: The American Academy of Dermatology/International League of Dermatological Societies Dermatology COVID-19, Mpox, and Emerging Infections Registry captured deidentified patient cases of mpox entered by health care professionals. RESULTS: From August 4 to November 13, 2022, 101 cases from 13 countries were entered, primarily by dermatologists (92%). Thirty-nine percent had fewer than 5 lesions. In 54% of cases, skin lesions were the first sign of infection. In the first 1-5 days of infection, papules (36%), vesicles (17%), and pustules (20%) predominated. By days 6-10, pustules (36%) were most common, followed by erosions/ulcers (27%) and crusts/scabs (24%). Crusts/scabs were the predominant morphology after day 11. Ten cases of morbilliform rash were reported. Scarring occurred in 13% of the cases. LIMITATIONS: Registry-reported data cannot address incidence. There is a potential reporting bias from the predilection to report cases with greater clinical severity. DISCUSSION: These findings highlight differences in skin findings compared to historical outbreaks, notably the presence of skin lesions prior to systemic symptoms and low overall lesion counts. Scarring emerged as a major possible sequela.

The American Academy of Dermatology and International League of Dermatological Societies Monkeypox Registry: Expanding the COVID-19 registry to emerging infections.

The World Health Organization declared the global monkeypox outbreak a public health emergency of international concern in July 2022. In response, the American Academy of Dermatology and International League of Dermatological Societies expanded the existing COVID-19 Dermatology Registry to become the "AAD/ILDS Dermatology COVID-19, Monkeypox, and Emerging Infections Registry." The goal of the registry is to rapidly collate cases of monkeypox and other emerging infections and enable prompt dissemination of findings to front-line healthcare workers and other members of the medical community. The registry is now accepting reports of monkeypox cases and cutaneous reactions to monkeypox/smallpox vaccines. The success of this collaborative effort will depend on active case entry by the global dermatology community.

Number of comorbidities and their impact on perioperative outcome and costs - a single centre cohort study.

AIMS OF THE STUDY: Multimorbidity is a growing global health problem, resulting in an increased perioperative risk for surgical patients. Data on both the prevalence of multimorbidity and its impact on perioperative outcome are limited. The American Society of Anesthesiologists (ASA) classification uses only the single most severe systemic disease to define the ASA class and ignores multimorbidity. This study aimed to assess the number and type of all anaesthesia-relevant comorbidities and to analyse their impact on outcome and hospital costs. METHODS: This cohort study is nested in the ClassIntra® validation study and includes only patients enrolled at the University Hospital of Basel. Approximately 30 patients per surgical discipline undergoing any type of in-hospital surgery were followed up until hospital discharge to record all intra- and postoperative adverse events. In addition, the type and severity of all perioperatively relevant comorbidities were extracted from the electronic medical record according to a predefined list. The primary endpoint was the number of all anaesthesia-relevant comorbidities by ASA class. Using structural equation models, the direct and indirect effects of comorbidities on costs were estimated after adjustment for the ASA class and further relevant confounders and mediators. RESULTS: Of 320 enrolled patients, 27 were ASA I (8%), 150 ASA II (47%), 116 ASA III (36%) and 27 ASA IV (8%). The median number of comorbidities per patient was 5 (range 0-18), this number significantly increasing with higher ASA class: 1 comorbidity (95% CI 0.0-2.0) in ASA I, 4 comorbidities (3.8-4.2) in ASA II, 9 (8.1-9.9) in ASA III and 12 (10-14) in ASA IV patients. Independent of ASA class, each additional comorbidity increased hospital costs by EUR 1,198 (95% CI 288-2108) with almost identical proportions of direct and indirect effects. The number of anaesthesia-relevant comorbidities also increased postoperative complications and postoperative length of hospital stay. CONCLUSIONS: Multimorbidity in perioperative patients is highly prevalent and has a relevant impact on hospital costs, independent of the ASA class. Incorporating multimorbidity into the ASA classification might be warranted to improve its predictive ability and support adequate reimbursement.

The SARS-CoV-2 Pandemic Impacts the Management of Swiss Pediatric Intensive Care Units.

The impact of the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) pandemic on pediatric intensive care units (PICUs) is difficult to quantify. We conducted an observational study in all eight Swiss PICUs between 02/24/2020 and 06/15/2020 to characterize the logistical and medical aspects of the pandemic and their impact on the management of the Swiss PICUs. The nine patients admitted to Swiss PICUs during the study period suffering from pediatric inflammatory multisystem syndrome temporally associated with SARS-CoV-2 (PIMS-TS) and constituting 14% (9/63) of all SARS-CoV-2 positive hospitalized patients in Swiss children's hospitals caused a higher workload [total Nine Equivalents of nursing Manpower use Score (NEMS) points, p = 0.0008] and were classified to higher workload categories (p < 0.0001) than regular PICU patients (n = 4,881) admitted in 2019. The comparison of the characteristics of the eight Swiss PICUs shows that they were confronted by different organizational issues arising from temporary regulations put in place by the federal council. These general regulations had different consequences for the eight individual PICUs due to the differences between the PICUs. In addition, the temporal relationship of these different regulations influenced the available PICU resources, dependent on the characteristics of the individual PICUs. As pandemic continues, reflecting and learning from experience is essential to reduce workload, optimize bed occupancy and manage resources in each individual PICU. In a small country as Switzerland, with a relatively decentralized health care local differences between PICUs are considerable and should be taken into account when making policy decisions.

Gender differences in the provision of intensive care: a Bayesian approach.

PURPOSE: It is currently unclear whether management and outcomes of critically ill patients differ between men and women. We sought to assess the influence of age, sex and diagnoses on the probability of intensive care provision in critically ill cardio- and neurovascular patients in a large nationwide cohort in Switzerland. METHODS: Retrospective analysis of 450,948 adult patients with neuro- and cardiovascular disease admitted to all hospitals in Switzerland between 01/2012 and 12/2016 using Bayesian modeling. RESULTS: For all diagnoses and populations, median ages at admission were consistently higher for women than for men [75 (64;82) years in women vs. 68 (58;77) years in men, p < 0.001]. Overall, women had a lower likelihood to be admitted to an intensive care unit (ICU) than men, despite being more severely ill [odds ratio (OR) 0.78 (0.76-0.79)]. ICU admission probability was lowest in women aged > 65 years (OR women:men 0.94 (0.89-0.99), p < 0.001). Women < 45 years had a similar ICU admission probability as men in the same age category [OR women:men 1.03 (0.94-1.13)], in spite of more severe illness. The odds to die were significantly higher in women than in men per unit increase in Simplified Acute Physiology Score (SAPS) II (OR 1.008 [1.004-1.012]). CONCLUSION: In the care of the critically ill, our study suggests that women are less likely to receive ICU treatment regardless of disease severity. Underuse of ICU care was most prominent in younger women < 45 years. Although our study has several limitations that are imposed by the limited data available from the registries, our findings suggest that current ICU triage algorithms could benefit from careful reassessment. Further, and ideally prospective, studies are needed to confirm our findings.

Severity-Adjusted ICU Mortality Only Tells Half the Truth-The Impact of Treatment Limitation in a Nationwide Database.

OBJECTIVES: The influence of different forms of treatment limitation on mortality rate in the ICU is not known despite the common use of the latter as a quality indicator. The aim of the present study was to assess the prevalence of treatment limitation and its influence on ICU mortality rate. Primary outcomes were prevalence of treatment limitation and its influence on severity-adjusted ICU mortality rate. Secondary outcomes included the association of limitation with age, sex, type of admission, diagnostic group, treatment intensity, and length of ICU stay. DESIGN: Retrospective, observational study. SETTING: All Swiss adult ICUs. INTERVENTIONS: None. PATIENTS: A total of 166,764 patients were admitted to an ICU in 2016 and 2017. Of these, 9139 were excluded because of readmission or invalid coding. MEASUREMENTS AND MAIN RESULTS: Of 157,625 ICU patients, 20,916 (13.3%) had a fully defined treatment limitation. Among this group, treatment limitation was defined upon ICU admission in 12,854 (61%), the decision to limit treatment was based on the patient's advance directives in 9,951 (48%), and in 15,341 (73%), there was a decision to deliberately withhold certain treatment modalities. The mortality odds ratio for the group with a treatment limitation, considering relevant cofactors, was 18.1 (95% CI 16.8-19.4). CONCLUSIONS: Every seventh patient in a Swiss ICU has some kind of treatment limitation, and this most probably affects the severity-adjusted mortality rate. Thus, mortality data as a quality indicator or benchmark in intensive care can only meaningfully be interpreted if existence, grade, cause, and time of treatment limitation are taken into account.

A novel method to assess data quality in large medical registries and databases.

BACKGROUND: There is no gold standard to assess data quality in large medical registries. Data auditing may be impeded by data protection regulations. OBJECTIVE: To explore the applicability and usefulness of funnel plots as a novel tool for data quality control in critical care registries. METHOD: The Swiss ICU-Registry from all 77 certified adult Swiss ICUs (2014 and 2015) was subjected to quality assessment (completeness/accuracy). For the analysis of accuracy, a list of logical rules and cross-checks was developed. Type and number of errors (true coding errors or implausible data) were calculated for each ICU, along with noticeable error rates (>mean + 3 SD in the variable's summary measure, or >99.8% CI in the respective funnel-plot). RESULTS: We investigated 164 415 patient records with 31 items each (37 items: trauma diagnosis). Data completeness was excellent; trauma was the only incomplete item in 1495 of 9871 records (0.1%, 0.0%-0.6% [median, IQR]). In 15 572 patients records (9.5%), we found 3121 coding errors and 31 265 implausible situations; the latter primarily due to non-specific information on patients' provenance/diagnosis or supposed incoherence between diagnosis and treatments. Together, the error rate was 7.6% (5.9%-11%; median, IQR). CONCLUSIONS: The Swiss ICU-Registry is almost complete and data quality seems to be adequate. We propose funnel plots as suitable, easy to implement instrument to assist in quality assurance of such a registry. Based on our analysis, specific feedback to ICUs with special-cause variation is possible and may promote such ICUs to improve the quality of their data.

Timing of surgical antimicrobial prophylaxis: a phase 3 randomised controlled trial.

BACKGROUND: Based on observational studies, administration of surgical antimicrobial prophylaxis (SAP) for the prevention of surgical site infection (SSI) is recommended within 60 min before incision. However, the precise optimum timing is unknown. This trial compared early versus late administration of SAP before surgery. METHODS: In this phase 3 randomised controlled superiority trial, we included general surgery adult inpatients (age ≥18 years) at two Swiss hospitals in Basel and Aarau. Patients were randomised centrally and stratified by hospital according to a pre-existing computer-generated list in a 1:1 ratio to receive SAP early in the anaesthesia room or late in the operating room. Patients and the outcome assessment team were blinded to group assignment. SAP consisted of single-shot, intravenous infusion of 1·5 g of cefuroxime, a commonly used cephalosporin with a short half-life, over 2-5 min (combined with 500 mg metronidazole in colorectal surgery). The primary endpoint was the occurrence of SSI within 30 days of surgery. The main analyses were by intention to treat. The trial is registered with ClinicalTrials.gov, number NCT01790529. FINDINGS: Between Feb 21, 2013, and Aug 3, 2015, 5580 patients were randomly assigned to receive SAP early (2798 patients) or late (2782 patients). 5175 patients (2589 in the early group and 2586 in the late group) were analysed. Median administration time was 42 min before incision in the early group (IQR 30-55) and 16 min before incision in the late group (IQR 10-25). Inpatient follow-up rate was 100% (5175 of 5175 patients); outpatient 30-day follow-up rate was 88·8% (4596 of 5175), with an overall SSI rate of 5·1% (234 of 4596). Early administration of SAP did not significantly reduce the risk of SSI compared with late administration (odds ratio 0·93, 95% CI 0·72-1·21, p=0·601). INTERPRETATION: Our findings do not support any narrowing of the 60-min window for the administration of a cephalosporin with a short half-life, thereby obviating the need for increasingly challenging SAP timing recommendations.

[Anesthesia for ophthalmic surgery]. / Anästhesie bei ophthalmologischen Operationen - eine Standortbestimmung.

The majority of ophthalmic interventions can be done today under locoregional anesthesia using "Monitored Anesthesia Care" (MAC). General anesthesia techniques are mostly reserved for the pediatric segment and for patients with specific comorbidity and/or lengthy procedure. Cataract surgery in predominantly geriatric patients belongs to the field of the so-called "high volume-surgery": Given the low perioperative risk in this patient group, adapted and optimized processes are indicated. A focused premedication and informing these patients ensures good perioperative compliance. Preoperative tests are be conducted in this patient population only as a function of relevant comorbidity. Premedication usually takes place as a classical anesthesia consultation, but new methods such as an internet-based premedication for healthy patients offers a new option. The intraoperative anesthesia method depends on the needs of the surgeon and the expectations and possibilities of cooperation of the patient.

SwissScoring--a nationwide survey of SAPS II assessing practices and its accuracy.

OBJECTIVE: The first description of the simplified acute physiology score (SAPS) II dates back to 1993, but little is known about its accuracy in daily practice. Our purpose was to evaluate the accuracy of scoring and the factors that affect it in a nationwide survey. METHODS: Twenty clinical scenarios, covering a broad range of illness severities, were randomly assigned to a convenience sample of physicians or nurses in Swiss adult intensive care units (ICUs), who were asked to assess the SAPS II score for a single scenario. These data were compared to a reference that was defined by five experienced researchers. The results were cross-matched with demographic characteristics and data on the training and quality control for the scoring, structural and organisational properties of each participating ICU. RESULTS: A total of 345 caregivers from 53 adult ICU providers completed the SAPS II evaluation of one clinical scenario. The mean SAPS II scoring was 42.6 ± 23.4, with a bias of +5.74 (95%CI 2.0-9.5) compared to the reference score. There was no evidence of bias variation according to the case severity, ICU size, linguistic area, profession (physician vs. nurse), experience, initial SAPS II training, or presence of a quality control system. CONCLUSION: This nationwide survey revealed substantial variability in the SAPS II scoring results. On average, SAPS II scoring was overestimated by more than 13%, irrespective of the profession or experience of the scorer or of the structural characteristics of the ICUs.
