Aligning mission to digital health strategy in academic medical centers.

The strategies of academic medical centers arise from core values and missions that aim to provide unmatched clinical care, patient experience, research, education, and training. These missions drive nearly all activities. They should also drive digital health activities - and particularly now given the rapid adoption of digital health, marking one of the great transformations of healthcare; increasing pressures on health systems to provide more cost-effective care; the pandemic-accelerated funding and rise of well-funded new entrants and technology giants that provide more convenient forms of care; and a more favorable regulatory and reimbursement landscape to incorporate digital health approaches. As academic medical centers emerge from a pandemic-related reactionary digital health posture, where pressures to adopt more digital health technologies mount, a broad digital health realignment that leverages the strengths of such centers is required to accomplish their missions.

Real-world assessment of severe acute respiratory coronavirus virus 2 (SARS-CoV-2) nasopharyngeal swab testing in a region with a high burden of coronavirus disease 2019 (COVID-19).

Concerns persist regarding possible false-negative results that may compromise COVID-19 containment. Although obtaining a true false-negative rate is infeasible, using real-life observations, the data suggest a possible false-negative rate of ˜2.3%. Use of a sensitive, amplified RNA platform should reassure healthcare systems.

Universal SARS-CoV-2 Testing of Emergency Department Admissions Increases Emergency Department Length of Stay.

STUDY OBJECTIVE: Our institution experienced a change in SARS-CoV-2 testing policy as well as substantial changes in local COVID-19 prevalence, allowing for a unique examination of the relationship between SARS-CoV-2 testing and emergency department (ED) length of stay. METHODS: This was an observational interrupted time series of all patients admitted to an academic health system between March 15, 2020, and September 30, 2020. Given testing limitations from March 15 to April 24, all patients receiving SARS-CoV-2 tests were symptomatic. On April 24, testing was expanded to all ED admissions. The primary and secondary outcomes were ED length of stay and number needed to test to obtain a positive, respectively. RESULTS: A total of 70,856 patients were cared for in the EDs during the 7-month period. The testing change increased admission length of stay by 1.89 hours (95% confidence interval 1.39 to 2.38). The number needed to test was 2.5 patients and was highest yield on April 1, 2020, when the state positivity rate was 39.7%; however, the number needed to test exceeded 170 patients by Sept 1, 2020, at which point the state positivity rate was 0.5%. CONCLUSION: Although universal SARS-CoV-2 testing of ED admissions may meaningfully support mitigation and containment efforts, the clinical cost of testing all admissions amid low community positivity is notable. In our system, universal ED SARS-CoV-2 testing was associated with a 24% increase in admission length of stay alongside the detection of only 1 positive case every other day. Given the known harms and risks of ED boarding and crowding, solutions must be developed to support regular operational flow while balancing infection prevention needs.

Mass severe acute respiratory coronavirus 2 (SARS-CoV-2) testing of asymptomatic healthcare personnel.

Mass asymptomatic SARS-CoV-2 nucleic acid amplified testing of healthcare personnel (HCP) was performed at a large tertiary health system. A low period-prevalence of positive HCP was observed. Of those who tested positive, half had mild symptoms in retrospect. HCP with even mild symptoms should be isolated and tested.

Improving laboratory test utilisation at the multihospital Yale New Haven Health System.

BACKGROUND: Waste persists in healthcare and negatively impacts patients. Clinicians have direct control over test ordering and ongoing international efforts to improve test utilisation have identified multifaceted approaches as critical to the success of interventions. Prior to 2015, Yale New Haven Health lacked a coherent strategy for laboratory test utilisation management. METHODS: In 2015, a system-wide laboratory formulary committee was formed at Yale New Haven Health to manage multiple interventions designed to improve test utilisation. We report here on specific interventions conducted between 2015 and 2017 including reduction of (1) obsolete or misused testing, (2) duplicate orders, and (3) daily routine lab testing. These interventions were driven by a combination of modifications to computerised physician order entry, test utilisation dashboards and physician education. Measurements included test order volume, blood savings and cost savings. RESULTS: Testing for a number of obsolete/misused analytes was eliminated or significantly decreased depending on alert rule at order entry. Hard stops significantly decreased duplicate testing and educational sessions significantly decreased daily orders of routine labs and increased blood savings but the impact waned over time for select groups. In total, we realised approximately $100 000 of cost savings during the study period. CONCLUSION: Through a multifaceted approach to utilisation management, we show significant reductions in low-value clinical testing that have led to modest but significant savings in both costs and patients' blood.

Using System Inflammatory Response Syndrome as an Easy-to-Implement, Sustainable, and Automated Tool for All-Cause Deterioration Among Medical Inpatients.

OBJECTIVES: Clinical deterioration detection among adult inpatients is known to be suboptimal, and many electronic health record tools have been developed to help identify these patients. Many of these tools are focused on sepsis spectrum disorders, but the evolution of the definition of sepsis is moving toward increased specificity, which may make automated detection of clinical deterioration from nonsepsis-related conditions less likely. The objectives of this study were to develop and to examine the use of a low-cost, highly sustainable deterioration detection tool based on systemic inflammatory response syndrome (SIRS) criteria. METHODS: Using existing resources, a SIRS-based electronic health record monitoring and intervention tool was developed with a focus on ease of implementation and high sustainability. This tool was used to monitor 15,739 adult inpatients in real time during their admission. RESULTS: The SIRS-based tool, created with focus on ease of implementation and high sustainability, identified patients with higher risk of clinical deterioration. The project was rapidly deployed for a 4-month period at a 900-bed campus of an academic medical center with minimal additional resources required. CONCLUSIONS: Whereas the definition of sepsis moves away from SIRS, SIRS-based criteria may still have clinical benefit as an easy-to-automate detection tool for all-cause clinical deterioration among medical inpatients.

Eliminating Inappropriate Telemetry Monitoring: An Evidence-Based Implementation Guide.

In-hospital continuous electrocardiographic monitoring, commonly referred to as telemetry, has allowed for rapid recognition of life-threatening conditions, including complex arrhythmias and myocardial ischemia. However, inappropriate use can lead to unnecessary downstream testing from "false alarms," which in turn affects clinician efficiency and increases health care costs without benefiting patients. For these reasons, the Society of Hospital Medicine's Choosing Wisely campaign recommended use of a protocol-driven discontinuation of telemetry. The American Heart Association (AHA) developed a set of Practice Standards for the appropriate use of telemetry monitoring in 2004, which they updated in 2017. Unfortunately, the AHA Practice Standards have not been widely adopted-with as many as 43% of monitored patients lacking a recommended indication for monitoring. Thus, we created an overview discussing the safety and efficacy of incorporating the AHA Practice Standards and a review of studies highlighting their successful incorporation within patient care workflow. We conclude by outlining an "implementation blueprint" for health system professionals and administrators seeking to change their institution's culture of telemetry use. As the health care landscape continues to shift, enacting high-value initiatives that improve patient safety and efficiency of care will be critical.

Restricting symptoms in the last year of life: a prospective cohort study.

IMPORTANCE: Freedom from symptoms is an important determinant of a good death, but little is known about symptom occurrence during the last year of life. OBJECTIVE: To evaluate the monthly occurrence of physical and psychological symptoms leading to restrictions in daily activities (ie, restricting symptoms) among older persons during the last year of life and to determine the associations of demographic and clinical factors with symptom occurrence. DESIGN, SETTING, AND PARTICIPANTS: Prospective cohort study. Comprehensive assessments were completed every 18 months, and monthly interviews were conducted to assess the presence of restricting symptoms. Of 1002 nondisabled community-dwelling individuals 70 years or older in greater New Haven, Connecticut, eligible to participate, 754 agreed and were enrolled between 1998 and 1999. MAIN OUTCOMES AND MEASURES: The primary outcome was the monthly occurrence of restricting symptoms as a dichotomous outcome. The monthly mean count of restricting symptoms was a secondary outcome. RESULTS: Among the 491 participants who died after their first interview and before June 30, 2011, mean age at death was 85.8 years, 61.9% were women, and 9.0% were nonwhite. The mean number of comorbid conditions was 2.4, and 73.1% had multimorbidity. The monthly occurrence of restricting symptoms was fairly constant from 12 months before death (20.4%) until 5 months before death (27.4%), when it began to increase rapidly, reaching 57.2% in the month before death. In multivariable analysis, age younger than 85 years (odds ratio [OR], 1.30 [95% CI, 1.07-1.57]), multimorbidity (OR, 1.38 [95% CI, 1.09-1.75]), and proximity to time of death (OR, 1.14 per month [95% CI, 1.11-1.16]) were significantly associated with the monthly occurrence of restricting symptoms. Participants who died of cancer had higher monthly symptom occurrence (OR, 1.80 [95% CI, 1.03-3.14]) than participants who died of sudden death, although this difference was only marginally significant (P = .04). Symptom burden did not otherwise differ substantially according to condition leading to death. CONCLUSIONS AND RELEVANCE: Restricting symptoms are common during the last year of life, increasing substantially approximately 5 months before death. Our results highlight the importance of assessing and managing symptoms in older patients, particularly those with multimorbidity.

Ki67 antigen and PCNA proliferation markers predict survival in anorectal malignant melanoma.

AIMS: To find a possible correlation of Ki67 antigen and proliferating cell nuclear antigen (PCNA) with prognosis in anorectal malignant melanoma. METHODS AND RESULTS: Thirty patients with anorectal malignant melanoma were studied. The percentage of tumour cells stained for Ki67 and PCNA in paraffin sections was assessed. Mode of treatment (local excision or abdominoperineal resection), depth of tumour invasion, attempt at cure as defined by complete tumour excision and absence of distant metastases at presentation, tumour blood vessel invasion, and tumour necrosis, as well as Ki67 and PCNA, were all correlated with survival. By univariate analysis, PCNA, Ki67, attempt at cure, local excision (and not abdominoperineal resection), and depth of invasion were all significantly associated with longer survival. By multivariate analysis, only PCNA was significantly associated with survival, while Ki67 showed a significant positive correlation with PCNA. With a cut-off point of 40%, patients with lower Ki67 scores showed survival advantage over those with higher Ki67 scores (P=0.0004). With a cut-off point of 80%, patients with lower PCNA scores showed survival advantage over those with higher PCNA scores (P=0.0001). The staining for proliferation markers was also associated with depth of tumour invasion. CONCLUSIONS: Ki67 and PCNA immunostaining in paraffin sections may be useful for the prediction of survival in patients with anorectal malignant melanoma. Larger studies are needed to confirm our results.

Nicotine patch and paroxetine for smoking cessation.

Smokers (N = 224) were randomized to 1 of 3 groups: (a) transdermal system (TNS) + placebo; (b) TNS + paroxetine (20 mg); (c) TNS + paroxetine (40 mg). Assignment to treatment was double-blind. Nicotine patch (TNS) treatment was provided for 8 weeks; paroxetine or placebo was provided for 9 weeks. Abstinence rates at Weeks 4, 10, and 26 were as follows: (a) TNS + placebo: 45%, 36%, and 25%; (b) TNS + paroxetine (20 mg): 48%, 33%, and 21%; (c) TNS + paroxetine (40 mg): 57%, 39%, and 27%. The differences were not statistically significant. The combined treatment was more effective in reducing both craving and depression symptoms associated with smoking cessation. A subgroup analysis comparing compliant participants was also conducted. Abstinence rates at Weeks 4, 10, and 26 were as follows: (a) TNS + placebo: 46%, 35%, and 24%; (b) TNS + paroxetine (20 mg): 64%, 43%, and 33%; (c) TNS + paroxetine (40 mg): 74%, 51%, and 38%. The differences between paroxetine groups and placebo at Week 4 were statistically significant. Although paroxetine may add value to the current standard of care in excess of potential risk, more conclusive evidence is needed.

Randomized clinical trial of early laparoscopy in the management of acute non-specific abdominal pain.

BACKGROUND: Abdominal pain of uncertain aetiology (non-specific abdominal pain; NSAP) is the commonest reason for emergency surgical admission. The aim of this study was to examine the role of early laparoscopy in the management of NSAP. METHODS: Some 120 patients, admitted between November 1995 and October 1998 with acute abdominal pain of uncertain aetiology, were randomized into two groups: group 1 had laparoscopy during the first 18 h of admission and group 2 had close observation, conventional investigation and surgical intervention if signs of peritonism developed. Outcome measures were diagnosis, operative procedures, duration of hospital stay, readmission rate, morbidity and death, patient satisfaction and total number of investigations performed. RESULTS: Median hospital stay was 2 (range 1-13) days in both groups (P = 0.87). A diagnosis was established in 48 (81 per cent) of 59 patients in group 1 compared with 22 (36 per cent) of 61 in group 2 (P < 0.0001). The morbidity rate was 14 (24 per cent) of 59 in group 1 and 19 (31 per cent) of 61 in group 2 (P = 0.3629). The readmission rate at a median follow-up of 21 (range 1-35) months was 17 (29 per cent) of 59 in group 1 compared with 20 (33 per cent) of 61 in group 2 (P = 0. 6375). Well-being scores improved from 134 on admission to 149 of 177 6 weeks later in group 1 (P = 0.007) and from 132 to 143 of 177 in group 2 (P = 0.089). CONCLUSION: Early laparoscopy provided a higher diagnostic accuracy and improved quality of life in patients with NSAP.

A tool to organize instructions at discharge after treatment of asthmatic children in an emergency department.

Asthma exacerbations continue to be a major cause of visits to emergency departments (ED). Comprehensive care in the outpatient setting, with planning for early intervention for exacerbations, can reduce emergency visits. Thus, a major goal of ED intervention is to establish a link between the patient and the provider of ongoing asthma care, where complete education can be achieved and reinforced over time. When designing the Asthma 1-2-3 Plan discharge teaching tool for the ED, consideration was given to educational format, readability, patient population, and setting in which education was to be delivered. To evaluate use of the plan, ED records of patients enrolled in a separate asthma study, the Neighborhood Asthma Coalition (NAC), were audited for two 8-month intervals, May-December 1993 (before initiation of the plan) and May December 1994 (starting 1 month after completion of pilot testing on the plan in the ED). To evaluate effectiveness of the plan, records of physicians who cared for children in the NAC were evaluated. The database was reviewed for the date of the first visit for planned review of asthma that occurred after the acute asthma ED visit. After introduction of the plan, the proportion of children told to return to the physician for follow-up increased from 54% to 81%. The proportion of children given advice to return to their physician within the recommended 3 days or less increased from 11% to 54%. Chi2 Analyses showed that these changes were both statistically significant (p<0.0001). The plan was not effective in achieving increased follow-up visits for regular asthma care, in that 7% returned for follow-up within 7 days after an ED visit before the plan and only 6% returned for such a visit after the Plan. Successful initiation of a focused discharge teaching tool into the routine of the ED increased appropriate advice given at time of discharge from the ED. Although unsuccessful in increasing appropriate follow-up, the present intervention uses the ED not as a base for asthma education, but as a point for contacting patients in need of regular care and education, and for promoting access to that regular care.

p53-independent dephosphorylation and cleavage of retinoblastoma protein during tamoxifen-induced apoptosis in human breast carcinoma cells.

We have investigated several molecular events that occur during the process of tamoxifen-induced apoptosis in human breast carcinoma cells. We show that the treatment of either MCF-7 (containing wild-type p53) or MDA-MB-231 cells (containing mutant p53) with tamoxifen resulted in apoptotic nuclear changes and an increase in the pre-G1 apoptotic population. This was accompanied by activation of the caspase enzymes, as evidenced by specific cleavage of poly(ADP-ribose) polymerase and retinoblastoma (RB) protein. The RB protein was cleaved at both an interior and carboxyl terminus cleavage site. In addition, dephosphorylation of RB was found at an early stage of tamoxifen-induced apoptosis in both cell lines. However, neither induction of p53 in MCF-7 cells nor induction of p21 in either cell line was detected, suggesting that tamoxifen-induced RB dephosphorylation and apoptosis are independent of the p53/p21 pathway. We also observed an increase in levels of the pro-apoptotic Bax protein, the inhibitory cytokine TGF-beta1 and the transcription factor c-Myc in tamoxifen-treated MDA-MB-231 cells, suggesting the possible involvement of these proteins during apoptosis in this system.

Randomised trial of laparoscopic exploration of common bile duct versus postoperative endoscopic retrograde cholangiography for common bile duct stones.

BACKGROUND: The management of stones in the common bile duct in the laparoscopic era is controversial. The three major options are preoperative endoscopic retrograde cholangiography (ERCP), laparoscopic exploration of the common bile duct (LECBD), or postoperative ERCP. METHODS: Between August, 1995, and August, 1997, 471 laparoscopic cholecystectomies were done in our department. In 427 (91%), satisfactory peroperative cholangiography was obtained. In 80 (17%) of these cases there were stones in the common bile duct, 40 patients were randomised to LECBD and 40 to postoperative ERCP. If LECBD failed, patients had either open exploration of the common bile duct or postoperative ERCP. If one postoperative ERCP failed, the procedure was repeated until the common bile duct was cleared of stones or an endoprosthesis was placed to prevent stone impaction. The primary endpoints were duct-clearance rates, morbidity, operating time, and hospital stay. Analyses were by intention to treat. FINDINGS: Age and sex distribution of patients was similar in the randomised groups. Duct clearance after the first intervention was 75% in both groups. By the end of treatment, duct clearance was 100% in the laparoscopic group compared with 93% in the ERCP group. Duration of treatment was a median of 90 min (range 25-310) in the laparoscopic group (including ERCPs for failed LECBD) compared with 105 min (range 60-255) in the postoperative ERCP group (p = 0.1, 95% CI for difference -5 to 40). Hospital stay was a median of 1 day (range 1-26) in the laparoscopic group compared with 3.5 days (range 1-11) in the ERCP group (p = 0.0001, 95% CI 1-2). INTERPRETATION: LECBD is as effective as ERCP in clearing the common bile duct of stones. There is a non-significant trend to shorter time in the operating theatre and a significantly shorter hospital stay in patients treated by LECBD.

Laparoscopic excision of distal pancreas including insulinoma.

A case of sporadic occult insulinoma treated by laparoscopic distal pancreatectomy using a laparoscopic ultrasound probe to facilitate localization of the insulinoma and a laparoscopic surgical stapler to transect the pancreas is presented. This is believed to be the first case description of a laparoscopic pancreatic resection.

Incompletely excised basal cell carcinoma: a management dilemma?

BACKGROUND: Reported recurrence rates for incompletely excised basal cell cancers (BCC) vary widely (30-67%), and the destructive potential of recurrent BCC is well known. When surgically treated BCC are reported by the pathologist as incompletely excised the surgeon is placed in the dilemma of whether to perform an immediate wider excision, or to reserve further treatment until there is clinical evidence of recurrence. The aim of the present study is to determine if there are any clinical or morphological features which may help in this management dilemma. METHODS: Middlemore Hospital histology records were reviewed. In 1986, 82 out of a total of 723 BCC excised were reported to be incompletely excised. The management and recurrence rates of the incompletely excised BCC were determined from the patient records and telephone follow up where necessary. The clinical and morphological features were correlated with the recurrence rates, with the aim of developing a management strategy. RESULTS: The overall recurrence rate was 30.0%. Median time to recurrence was 18.5 months (range 1.5-55 months). Neither the margin of incomplete resection (deep, lateral or both margins), the site of tumour, the histological variant, the sex of the patient, nor prior treatment had any discernible effect on recurrence rates. CONCLUSIONS: Observation is an acceptable management option in most situations, as only one-third of incompletely excised lesions needed further treatment. Most recurrences occurred early and careful follow up of these patients was indicated for at least 3 years.

Acceptability and feasibility of a community approach to asthma management: the Neighborhood Asthma Coalition (NAC).

Understanding of asthma and co-management between patient and physician improves outcome. Feasibility of programs to achieve these goals in underserved settings is not documented. We used the Precede-Proceed model to document (a) community acceptance of a program to engage peer support of asthma management and care; (b) program revision to emphasize greater attention to availability of care and promotional events as channels for education; (c) engagement of intended audiences in planning and implementation; (d) participation of parents in program activities; and (e) peer-based education/support to reach parents, including socially isolated parents whose children experience heightened morbidity.
