65 & Thrive: Improving Patient Length of Stay, Readmission, and Quality of Care by Becoming an Age-Friendly Hospital

Data indicates that older persons will increase in numbers along with having an increase of life expectancy in the United States. Kaiser Permanente Los Angeles Medical Center’s Utilization Department developed “65 & Thrive”—an age-specialized initiative to provide holistic care that preserves independence, quality of life, prevents functional and cognitive decline, and promotes both patients and their families to continue thriving. The initiative’s focus is guided by the 5 M’s model on mobility, medication, mentation, multi-morbidity, and what matters. Case management staff were given age-sensitivity trainings, improved workflows and made assessments that identified, addressed, and secured resources for patients throughout their hospitalization. Silver Angel volunteers were specially trained to prevent physical and mental decline and focused on activities to prevent delirium, depression and falls. The volunteers visited with patients daily for these interactions. The initiative was piloted in April 2020 on a stroke telemetry unit and since then the hospital has seen a significant decrease in the overall annual readmission rates by 3.1% when compared to 2019. The average length of stay for older adult patients; however, increased from 4.05 to 4.83 days unfortunately due to COVID-19. This initiative demonstrates the necessity to expand “65 & Thrive” throughout the hospital and ultimately to other Kaiser Permanente medical centers to best provide holistic care to older adults.

65 & Thrive: Improving Patient Length of Stay, Readmission, and Quality of Care by Becoming an Age-Friendly Hospital

Despite its importance for health and wellbeing, oral health quality of life (OHQoL) has received little attention in lower-income countries, such as Colombia. This study describes the prevalence of older adults’ OHQoL and variability by socioeconomic status. We use data from the 2015 SABE-Colombia (N=18,700), a nationally representative survey of community-dwelling Colombians ages 60 and older. We used the Simple Count Geriatric Oral Health Assessment Index (SC-GOHAI), a self-reported measure of frequent oral health problems such as chewing, swallowing, and speaking designed to assess OHQoL. The scale ranges from 0-12; higher scores indicate worse OHQoL. About 69% of older Colombians reported at least one OHQoL problem. The most common issues were difficulty chewing hard food and speaking. High education and income were associated with better OHQoL and smoking were associated with worse OHQoL. Oral health may therefore reflect another dimension of social and health inequality for older Colombians.

Physical, Mental Health and Developmental Conditions, and Sociodemographic Characteristics Associated With Adverse Childhood Experiences Among Young Children in Pediatric Primary Care

Introduction To examine associations between patient characteristics and adverse childhood experiences (ACEs) in a population-based sample of pediatric primary care patients, using electronic health records and clinical, administrative data. Method An observational study was conducted in an integrated health care delivery system. Children ages 1–5 years (N = 13,370) were screened for ACEs at routine well-child visits between September 1, 2018 and May 31, 2019 in three pediatrics clinics. Multivariate models examined associations between patient characteristics (age, gender, race/ethnicity, insurance type, neighborhood income and education level, physical, mental health and developmental diagnoses, weight status) and any ACEs, and ≥ 3 ACEs exposure. Results Prevalence and severity of ACE exposure varied by race/ethnicity. Older age, Medicaid insurance, epilepsy/seizure disorder, sleeping disorders, adjustment disorders, and feeding disorders were associated with higher odds of ACEs exposure, higher-income with lower odds. Discussion Understanding relationships between ACEs and patient features can provide information to clinicians for early detection and appropriate interventions.

Variables Affecting Basal Cell Carcinoma and Melanoma In Situ Excision Clearance: A Multi-institutional Retrospective Study.

The primary endpoint for surgical excision of skin cancer is the positive margin status. Tumor characteristics may explain much of this risk, but other important factors can include physician specialty. To determine the variables affecting the success of a basal cell carcinoma (BCC) or melanoma in situ (MIS) excision. An 8-year, multicenter, retrospective study of 5,800 BCC or MIS excisions performed at 13 different Kaiser Permanente medical centers. The margin status was determined by searching final pathology diagnosis texts for phrases associated with positive margins. An incomplete excision rate was found in 23% of all specimens (BCC-22%, MIS-25%). Per specialty, the proportion of specimens with positive tumor margins was 24% for dermatology, 26% for plastic surgery, 28% for otolaryngology, and 12% for general surgery. General surgeons most often excised large tumors and tumors from truncal regions, 2 variables conferring lower odds of an incomplete excision. For non-Mohs procedures, dermatologists were no different than otolaryngologists or plastic surgeons in performing an incomplete BCC or MIS excision in all multivariate models (all p > .05). Intrinsic tumor characteristics may influence the success of achieving tumor-free resection margins more than the specialty of the provider.

Impact of Intraoperative Foley Catheters on Postoperative Urinary Retention after Inguinal Hernia Surgery

Foley catheters (FCs) are often used during inguinal hernia operations; however, the impact of intraoperative FC use on postoperative urinary retention (POUR) is not well understood. We reviewed unplanned returns to the urgent care or ED for 27,012 inguinal hernia operations across 15 Southern California Kaiser Permanente medical centers over 6.5 years. In total, 239 (0.88%) patients returned to urgent care/ED with POUR [235 (98%) men versus 4 (2%) women]. Overall, POUR increased with age (P < 0.00001). POUR was higher in open repairs using general anesthesia versus local with monitored anesthesia care (0.7% vs 0.3%, P < 0.0001). Of 5,017 laparoscopic operations, 28 per cent had FC use. Although POUR was greater for laparoscopic versus open operations (2.21 vs 0.58%, P < 0.00001), there was no difference in POUR for intraoperative FC versus no FC use in the laparoscopic approach (2.36% vs 2.15%, P = 0.33). For all laparoscopic operations, there was no difference in urinary tract infection within 7 or 30 days when comparing intraoperative FC versus no FC use (P = 0.28). POUR can be minimized by avoiding general anesthesia for open inguinal hernia repairs, but intraoperative FC use does not affect POUR or urinary tract infection rates for laparoscopic inguinal hernia repair.

Patients preference in receiving phone call from oncologist after cancer diagnosis and before in person consultation.

e18044 Background: Diagnosis of cancer creates an emotionally challenging time for patients. Waiting period between receiving diagnosis, and formal consultation with an Oncologist is associated with fear, shock, and uncertainty. Understanding patients’ preferences during this sensitive period is essential in providing high quality care. We hypothesized that receiving a call from an Oncologist, while waiting for a formal consultation, would help patients cope with cancer diagnosis. Methods: To assess our hypothesis, we surveyed 171 patients across five Kaiser Permanente medical centers. All patients received a call from an Oncology navigator to onboard them, and assure completion of necessary tests before in-person consultation with Oncologist. Of the 171 patients surveyed, 61 patients received an additional call from their assigned Oncologist before a formal in-person consultation. To understand the impact of the call made by the Oncologist, a survey was administered to patients within a few weeks of consultation. The remaining 110 patients who only received a call from an Oncology navigator were also surveyed to determine if a call from an Oncologist before their consultation could have helped them cope better with their cancer diagnosis. Results: Approximately 45 % of surveyed patients (n = 171) preferred a call from an Oncologist before the formal consultation. Conclusions: Brief telephone contact by Oncologist before in-person consultation supports newly diagnosed cancer patients with high-levels of uncertainty and shock. A substantial portion of newly diagnosed cancer patients prefers to speak with an Oncologists in the days after receiving a cancer diagnosis, and those who do receive an Oncologist call, find it beneficial in coping with their diagnosis.[Table: see text]

An Analysis of Early Postoperative Returns after Inguinal Hernia Surgery

Although inguinal herniorrhaphy is low risk, patients still return to the urgent care or ED. We performed a retrospective study on 19,296 inguinal hernia operations across 14 Southern California Kaiser Permanente medical centers over five years. Unplanned returns within the first postoperative week were evaluated focusing on four potentially avoidable diagnoses (AD): pain, constipation, urinary retention, and nausea/vomiting. Overall, 1370 (7%) patients returned to the urgent care/emergency department, of which 537 (39%) had an AD. There was no difference in total returns (7.1 vs 7.4%, P = 0.33) or AD returns [2.8 vs 2.6%, (P = 0.44)] for males vs females. Of the 537 total AD returns, there were 205 (38%) patients with pain, 191 (36%) with urinary retention, 112 (21%) with constipation, and 29 (5%) with nausea/vomiting. Most AD returns (78%) occurred within the first three postoperative days. Pain was greater in open operations [44 vs 26%, (P < 0.05)], and urinary retention was greater in the laparoscopic group [27 vs 55%, (P < 0.05)]. The overall rate of return was higher for laparoscopic compared with open unilateral operations [8 vs 6%, (P < 0.05)], but similar between approaches for bilateral operations [11 vs 10%, (P = 0.32)].

Cachexia, and not obesity, prior to pancreatic cancer diagnosis worsens survival and is negated by chemotherapy.

Although advanced pancreatic ductal adenocarcinoma (PDAC) is characterized by progressive weight loss and nutritional deterioration, the effect of cancer cachexia and body mass index (BMI) at diagnosis on survival remains unclear. We retrospectively evaluated a prospectively collected internal cancer registry of PDAC cases from 2006-2014 at the Kaiser Permanente Medical Center. Cancer cachexia was defined as weight loss greater than 5% over the 6 months prior to diagnosis. Multivariate cox proportional hazards regression was used to assess the influence of cachexia on survival. To evaluate effect measure modification of this relationship, we performed additional analyses stratified by race, BMI class, stage, receipt of surgery and receipt of chemotherapy. We tested for heterogeneity by fitting models with an interaction term for cachexia and the modifying variable. Of the 977 patients, 611 (63%) were identified with cachexia. Cachexia in PDAC patients was prevalent across all stages of disease and BMI classes. Patients with cachexia had lower survival (median 4.3 months, IQR 1.7-10.0) compared to those without cachexia (median 5.2 months, IQR 2.0-10.6), log-rank P=0.03. In this analysis BMI at diagnosis was not associated with survival. In the multivariate Cox regression, cachexia was independently associated with decreased overall survival (HR 1.24, CI: 1.06-1.45, P=0.01). However, the effect of cachexia on survival outcomes was modified by receipt of chemotherapy. Cachectic patients who did not receive chemotherapy had a 40% increase in risk of death compared to non-cachectic patients (HR 1.40, CI: 1.12-1.75), while those receiving chemotherapy were unaffected by cachexia (HR 1.04, CI: 0.82-1.32, Pinteraction=0.01). In the largest cohort of pancreatic cancer patients examined to date, cachexia and not obesity is independently associated with worse survival in PDA and its effect is negated by systemic chemotherapy.

An Enhanced Recovery After Surgery (ERAS) Protocol for Ambulatory Anorectal Surgery Reduced Postoperative Pain and Unplanned Returns to Care After Discharge

Ambulatory surgery for anorectal procedures has been proven to be safe and effective. Specific perioperative pathways combining multiple interventions have been shown to optimize recovery and outcomes associated with inpatient colorectal surgery. However, there are no major studies describing and evaluating a standardized protocol for ambulatory anorectal surgery. The purpose of this study was to evaluate the outcomes of a modified enhanced recovery after surgery (ERAS) protocol for ambulatory anorectal surgery. This was a retrospective review of prospectively collected data from 14 Southern California Kaiser Permanente medical centers. An eight-item protocol including: preoperative education, preoperative distribution of prescriptions, preoperative carbohydrate treatment, multimodal analgesia, preferential use of monitored anesthesia care (MAC), routine use of local anesthesia/regional blocks, intraoperative restriction of intravenous fluids, and post-discharge phone call. Postoperative pain scores and preventable returns to the emergency department or urgent care were assessed. Postoperative pain scores were reduced when all eight elements of the protocol were delivered (p=0.005). On multivariate analysis, there was reduced postoperative pain when preoperative carbohydrate treatment was completed (p=0.002), with MAC (p=0.003), and when multimodal analgesia was used (p=0.02). There were decreased preventable returns to the emergency department or urgent care when MAC was used (p=0.03); there were more returns for constipation (p=0.04) but fewer returns for pain (p=0.002) after preoperative carbohydrate treatment. Local anesthesia was associated with fewer returns for constipation (p=0.01). Implementation of a standardized ERAS protocol for ambulatory anorectal surgery decreased postoperative pain and unplanned return visits to emergency care.

Outcomes in Patients Treated with a Novel, Simple Method for Hemostasis of Dermal Avulsion Injuries.

A recently described technique proposes a simple method to achieve permanent hemostasis of distal fingertip dermal avulsion injuries. It is simple to learn and easy to perform with readily available materials found in most emergency departments. However, long-term outcomes for patients treated with this technique have not yet been evaluated. A primary objective of the current article is to provide safety data for the technique using an off-label product indication. Emergency department of Kaiser Permanente Medical Center, San Francisco, California. Six patients were treated in the emergency department for fingertip dermal avulsion injuries using a tourniquet and tissue adhesive glue (Dermabond by Ethicon, Somerville, New Jersey). Patients were subsequently contacted to assess healing and satisfaction with cosmetic outcome through interview and photographs of their wounds at 9 months following the date of injury. All 6 patients were satisfied with the cosmetic outcome of treatment, and none received a diagnosis of serious complications. This series demonstrates cosmetic outcomes for injuries treated with the technique, highlights potential problems that may be perceived by patients during their clinical course, and creates the groundwork for a larger clinical study examining the use of the technique.

Palliative Care Processes Embedded in the ICU Workflow May Reserve Palliative Care Teams for Refractory Cases.

Palliative Care Teams have been shown to be instrumental in the early identification of multiple aspects of advanced care planning. Despite an increased number of services to meet the rising consultation demand, it is conceivable that the numbers of palliative care consultations generated from an ICU alone could become overwhelming for an existing palliative care team. Improve end-of-life care in the ICU by incorporating basic palliative care processes into the daily routine ICU workflow, thereby reserving the palliative care team for refractory situations. A structured, palliative care, quality-improvement program was implemented and evaluated in the ICU at Kaiser Permanente Medical Center in Hawaii. This included selecting trigger criteria, a care model, forming guidelines, and developing evaluation criteria. These included the early identification of the multiple features of advanced care planning, numbers of proactive ICU and palliative care family meetings, and changes in code status and treatment upon completion of either meeting. Early identification of Goals-of-Care, advance directives, and code status by the ICU staff led to a proactive ICU family meeting with resultant increases in changes in code status and treatment. The numbers of palliative care consultations also rose, but not significantly. Palliative care processes could be incorporated into a daily ICU workflow allowing for integration of aspects of advanced care planning to be identified in a systematic and proactive manner. This reserved the palliative care team for situations when palliative care efforts performed by the ICU staff were ineffective.

Same-Day Discharge in Laparoscopic Acute Non-Perforated Appendectomy

Small studies done during the past decade have demonstrated same-day discharge after appendectomy as an option for non-perforated appendicitis. Here we have examined a large cohort to confirm that same-day discharge in acute non-perforated appendicitis is a safe option. This was a retrospective study of patients from 14 Southern California Region Kaiser Permanente medical centers. All patients older than 18 years of age with acute, non-perforated appendicitis who underwent a laparoscopic appendectomy between 2010 and 2014 were included. We compared patients discharged on the day of surgery with patients hospitalized for 1 night. We examined readmission rates, complication rates, postoperative emergency department visits, postoperative diagnostic or therapeutic radiology visits, reoperations, and cost of treatment. The cohort was composed of 12,703 patients; 6,710 patients were in the same-day discharge group and 5,993 patients were in the hospitalized group. Patients in the same-day discharge group had a lower rate of readmission within 30 days when compared with the hospitalized group (2.2% vs 3.1%; p < 0.005). In both groups, postoperative rates of visits to emergency or radiology department for diagnostic or therapeutic imaging studies were statistically similar. Postoperative general surgery department visits were slightly higher in the hospitalized group (85% vs 81%; p < 0.001). Adult patients with acute, non-perforated appendicitis can be discharged safely on the day of surgery without higher rates of postoperative complication or readmission rates compared with those hospitalized after surgery. In addition, same-day discharge in this patient group is cost-effective.

External Validation of Early Weight Loss Nomograms for Exclusively Breastfed Newborns.

Nomograms that show hour-by-hour percentiles of weight loss during the birth hospitalization were recently developed to aid clinical care of breastfeeding newborns. The nomograms for breastfed neonates were based on a sample of 108,907 newborns delivered at 14 Kaiser Permanente medical centers in Northern California (United States). The objective of this study was to externally validate the published nomograms for newborn weight loss using data from a geographically distinct population. Data were compiled from the Penn State Milton S. Hershey Medical Center located in Hershey, PA. For singleton neonates delivered at ≥36 weeks of gestation between January 2013 and September 2014, weights were obtained between 6 hours and 48 hours (vaginal delivery) or 60 hours (cesarean delivery) for neonates who were exclusively breastfeeding. Quantile regression methods appropriate for repeated measures were used to estimate 50th, 75th, 90th, and 95th percentiles of weight loss as a function of time after birth. These percentile estimates were compared with the published nomograms. Of the 1,587 newborns who met inclusion criteria, 1,148 were delivered vaginally, and 439 were delivered via cesarean section. These newborns contributed 1,815 weights for vaginal deliveries (1.6 per newborn) and 893 weights for cesarean deliveries (2.0 per newborn). Percentile estimates from this Penn State sample were similar to the published nomograms. Deviations in percentile estimates for the Penn State sample were similar to deviations observed after fitting the same model separately to each medical center that made up the Kaiser Permanente sample. The published newborn weight loss nomograms for breastfed neonates were externally validated in a geographically distinct population.

Manual Dexterity Aptitude Testing

Currently there are few validated metrics for predicting surgical skill among otolaryngology residency applicants. To determine whether manual dexterity aptitude testing in the form of soap carving during otolaryngology residency interviews at Kaiser Permanente Medical Center Oakland predicts surgical skill at the time of graduation from otolaryngology residency programs. This study was conducted to determine how applicants with the best and worst soap carvings compared at the time of graduation with respect to various metrics including visuospatial ability and manual dexterity. Over the last 25 years, applicants to the residency program at Kaiser Permanente Oakland were required to carve soap during their residency interview. The 3 best and 3 worst soap carvings from 1990 through 2006 were determined. Of the individuals who carved those soaps, 62 qualified for the study and matriculated into otolaryngology residency programs. Surveys were sent to the 62 individuals' residency programs to evaluate those individuals on a 5-point Likert scale in various categories as well as to rank those individuals as being in the top 50% or bottom 50% of their graduating class. All else being equal, we hypothesized that applicants who had the manual dexterity and visuospatial skills to accurately carve a bar of soap would more likely possess the skills necessary to become a good surgeon. There was no difference between individuals with the best soap carvings and those with the worst soap carvings in all categories: cognitive knowledge, visuospatial ability, manual dexterity, decision making, and overall score (P > .10 for all categories). There was a 95% response rate, with 35 of 37 residency programs responding and 59 of 62 surveys returned. Manual dexterity aptitude testing in the form of soap carving does not appear to correlate with surgical skill at the time of graduation. Further studies need to be conducted to determine the role of manual dexterity and visuospatial aptitude testing in the otolaryngology application process.

Patients in the same-day discharge group had a lower rate of readmission within 30 days when compared with the hospitalized group (2.2% vs 3.1%; p < 0.005). In both groups, postoperative rates of visits to emergency or radiology department for diagnostic or therapeutic imaging studies were statistically similar. Postoperative general surgery department visits were slightly higher in the hospitalized group (85% vs 81%; p < 0.001).Adult patients with acute, non-perforated appendicitis can be discharged safely on the day of surgery without higher rates of postoperative complication or readmission rates compared with those hospitalized after surgery. In addition, same-day discharge in this patient group is cost-effective.

Referral to Telephonic Nurse Management Improves Outcomes in Women With Gestational Diabetes

Objective We sought to determine whether, among women with gestational diabetes mellitus, referral to a telephonic nurse management program was associated with lower risk of macrosomia and increased postpartum glucose testing. Study Design There was medical center–level variation in the percent of patients referred to a telephonic nurse management program at 12 Kaiser Permanente medical centers, allowing us to examine in a quasi-experimental design the associations between referral and outcomes. Results Compared with women from centers where the annual proportion of referral nurse management was 70% were less likely to have a macrosomic infant and more likely to have postpartum glucose testing (multiple-adjusted odds ratio, 0.75; 95% confidence interval, 0.57–0.98 and multiple-adjusted odds ratio, 22.96; 95% confidence interval, 2.56–3.42, respectively). Conclusion Receiving care at the centers with higher referral frequency to telephonic nurse management for gestational diabetes mellitus was associated with decreased risk of macrosomic infant and increased postpartum glucose testing.

Interpersonal Processes of Care and Cesarean Delivery in Two Health Care Settings

We examined whether interpersonal processes of care (IPC) were associated with cesarean delivery. We performed a cross-sectional study of 1308 postpartum women at Kaiser Permanente Medical Center in Walnut Creek, CA (KP-WC), and San Francisco General Hospital (SFGH) from 2004 to 2006. Using interview and medical record data, logistic regression analyses estimated the odds of cesarean delivery as a function of IPC domains. After adjustment for demographic and reproductive factors, women at KP-WC who reported higher scores for their provider's "elicitation of patient concerns and responsiveness" were less likely to have delivered by cesarean, whereas women who reported higher scores for "empowerment and self-care" were more likely. At KP-WC, women who reported low English proficiency were less likely to have delivered by cesarean than women who reported high proficiency. At SFGH, none of the IPC measures were significant; however, younger age was associated with a lower risk of cesarean delivery, whereas higher educational attainment was associated with an increased risk. To reduce record-high rates of cesarean delivery, more emphasis should be placed on addressing the nonmedical factors associated with operative delivery.

Referral to telephonic nurse management improves outcomes in women with gestational diabetes

We sought to determine whether, among women with gestational diabetes mellitus, referral to a telephonic nurse management program was associated with lower risk of macrosomia and increased postpartum glucose testing. There was medical center-level variation in the percent of patients referred to a telephonic nurse management program at 12 Kaiser Permanente medical centers, allowing us to examine in a quasi-experimental design the associations between referral and outcomes. Compared with women from centers where the annual proportion of referral nurse management was <30%, women who delivered from centers with an annual referral proportion >70% were less likely to have a macrosomic infant and more likely to have postpartum glucose testing (multiple-adjusted odds ratio, 0.75; 95% confidence interval, 0.57-0.98 and multiple-adjusted odds ratio, 22.96; 95% confidence interval, 2.56-3.42, respectively). Receiving care at the centers with higher referral frequency to telephonic nurse management for gestational diabetes mellitus was associated with decreased risk of macrosomic infant and increased postpartum glucose testing.
