The effect of a prospective intervention program with automated monitoring of hand hygiene performance in long-term and acute-care units at a Veterans Affairs medical center

OBJECTIVE

To measure the impact of an automated hand hygiene monitoring system (AHHMS) and an intervention program of complementary strategies on hand hygiene (HH) performance in both acute-care and long-term care (LTC) units.

DESIGN

Prospective, nonrandomized, before-and-after intervention study.

SETTING

Single Veterans Affairs Medical Center (VAMC), with 2 acute-care units and 6 LTC units.

METHODS

An AHHMS that provides group HH performance rates was implemented on 8 units at a VAMC from March 2021 through April 2022. After a 4-week baseline period and 2.5-week washout period, the 52-week intervention period included multiple evidence-based components designed to improve HH compliance. Unit HH performance rates were expressed as the number of dispenses (events) divided by the number of patient room entries and exits (opportunities) × 100. Statistical analysis was performed with a Poisson general additive mixed model.

RESULTS

During the 4-week baseline period, the median HH performance rate was 18.6 (95% CI, 16.5-21.0) for all 8 units. During the intervention period, the median HH rate increased to 21.6 (95% CI, 19.1-24.4; P < .0001), and during the last 4 weeks of the intervention period (exactly 1 year after baseline), the 8 units exhibited a median HH rate of 25.1 (95% CI, 22.2-28.4; P < .0001). The median HH rate increased from 17.5 to 20.0 (P < .0001) in LTC units and from 22.9 to 27.2 (P < .0001) in acute-care units.

CONCLUSIONS

The intervention was associated with increased HH performance rates for all units. The performance of acute-care units was consistently higher than LTC units, which have more visitors and more mobile veterans.

The andes of bladder stones: Gigantic bladder calculi in a patient with bladder outlet obstruction and hyperparathyroidism

60-year-old man with known chronic urinary retention (CUR) managed with clean intermittent catheterization (CIC); He presented with difficulty with CIC. A KUB revealed 13 cm in conglomeration bladder stones. Routine preoperative bloodwork revealed calcium >12 and a subsequent PTH was also elevated. Osteoporosis was confirmed on DEXA. Sestamibi parathyroid scan had increased uptake within one parathyroid gland. The patient underwent open suprapubic 92 gm prostatectomy with evacuation of 254 gm calcium phosphate bladder stones; this was followed by removal of the offending parathyroid gland. On follow up, the patient was voiding well with normalization of other symptoms related to hyperparathyroidism.

1213. The Effect of a Prospective Intervention Program with Automated Monitoring on Hand Hygiene Performance in Long-term and Acute Care Units at a Veteran Affairs Medical Center

Background

There is emerging evidence that implementation of an automated hand hygiene monitoring system (AHHMS) must be part of a multimodal hand hygiene (HH) program that includes complementary strategies. There are few published studies describing in detail the intervention strategies used with an AHHMS.

Methods

An AHHMS that provides group HH performance rates (100 x HH product dispenses divided by the number of room entries plus exits) was implemented on two Acute Care (AC) units and six long-term care (LTC) units at a Veterans Affairs Medical Center from March 2021 through April 2022. After a 4-week baseline period and 2.5-week washout period, the 52-week intervention period included many components, such as weekly huddles, unit nurse manager engagement, vendor provided clinician-based training and feedback, leadership support, unit recognition, signage and development of a new slogan to remind colleagues to perform HH. Statistical analysis was performed with a Poisson general additive mixed model.

Results

During the 4-week baseline period, the median HH performance rate was 18.6 (95% CI: [16.5, 21.0]) for all 8 units. During the intervention period, the median HH rate increased to 21.6 [19.1, 24.4], and during the last 4 weeks of the intervention period (exactly 1 year after baseline), the 8 units exhibited a median HH rate of 25.1 [22.2, 28.4], (p < 0.0001) [Figure 1]. The median HH rate increased from 17.5 to 20.0 (p < 0.0001) in LTC units and from 22.9 to 27.2 (p < 0.0001) in AC units. The intervention increased the use of hand sanitizer from 57.5% during baseline to 65.1% (p < 0.0001). The increase in HH rates was due to HH events increasing from 88,758 dispenses during the baseline to 123,722 dispenses during the last 4 weeks of the intervention. Direct observation results during the same periods showed HH compliance ranging from 61-86%. Figure 1

Emergence of Dalbavancin, Vancomycin, and Daptomycin Nonsusceptible Staphylococcus aureus in a Patient Treated With Dalbavancin: Case Report and Isolate Characterization

A patient with end-stage renal disease received 2 doses of dalbavancin for methicillin-resistant Staphylococcus aureus (MRSA) arteriovenous fistula infection and presented 5 weeks later with infective endocarditis secondary to vancomycin, daptomycin, and dalbavancin nonsusceptible MRSA. Resistance was associated with walK and scrA mutations, reduced long-chain lipid content, and reduced membrane fluidity.

Reduction of central line-associated bloodstream infections in a large acute care hospital in Midwest United States following implementation of a comprehensive central line insertion and maintenance bundle

Background

Central line-associated bloodstream infection (CLABSI) is a preventable medical condition that results in increased patient morbidity and mortality. We describe the impact of various quality improvement interventions on the incidence of CLABSI in an 848-bed community teaching hospital from 1 January 2013 to 31 December 2017.

Aim

To reduce CLABSI rates after implementation of a comprehensive central line insertion and maintenance bundle.

Methods

A comprehensive bundle of interventions was implemented incorporating the standard US Centers for Disease Control and Prevention bundle with additional measures such as root-cause analysis of all CLABSI cases, use of passive disinfection caps on vascular access ports, standardisation of weekly central venous catheter (CVC) site dressing changes, and use of antithrombotic and antimicrobial-coated CVCs with fewer lumens. A retrospective study evaluated CLABSI rates and time of CLABSI onset after CVC placement in both intensive care unit (ICU) and non-ICU settings.

Results

The annual number of CLABSI cases declined 68% (34 to 11 patients) from 2013 to 2017. There was a 30% decline in CVC days from years 2014 to 2017. Over the same period, CLABSI cases per 1000 CVC days decreased from 0.624 to 0.362: a 42% decline.

Conclusion

Following the implementation of a comprehensive bundle of interventions for CVC insertion and maintenance, we found a reduction in rates of CLABSI.

1168. Trends in Central-Line-Associated Blood Stream Infections in a Community Teaching Hospital: A Multi-Intervention Quality Improvement Project

Background

Central line-associated bloodstream infection (CLABSI) is a preventable medical condition that results in increased patient morbidity and mortality as well as increased medical costs. We sought to describe the impact of various quality improvement interventions on the incidence of CLABSI in a large 990-bed community teaching hospital from the period of January 1, 2013 to December 31, 2017.

Methods

Retrospective study of CLABSI events as defined by the CDC’s National Healthcare Safety Network was completed. Between 2013 to 2017, we introduced mandatory real-time root cause analysis for each CLABSI event to identify defects that could be used for quality improvement interventions. We implemented a bundle of interventions for proper central venous catheter (CVC) insertion and maintenance based on CDC recommendations and the results of the internal analysis. Interventions included utilizing chlorhexidine gluconate (CHG) skin preparation and maximum sterile barrier precautions, optimal site selection (avoiding femoral site), using antimicrobial-coated CVCs and antithrombotic Bioflo peripherally inserted central catheters (PICC), minimizing multi-lumen CVC and PICC use, de-escalating CVC to midline or preferential use of midline catheters while minimizing unnecessary PICC and CVC insertion, adding Curos disinfection caps on central lines and other vascular access sites, weekly scheduled CVC site dressing changes with Tegaderm CHG I.V. Securement Dressing, CHG baths for patients with CVCs, avoidance of blood culture draws from central lines, and daily review of line necessity with timely removal. Medical staff members received ongoing education on the implementation of the CLABSI bundle. Both ICU and non-ICU CLABSI cases in the adult patient population were analyzed.

Results

A comparison of 2013 with 2017 shows a 69% decline in a number of CLABSI cases from 36 to 11 patients (Figure 1). There was a 30% decline in CVC days from years 2014 to 2017 (No CVC days data for 2013 due to change in data collection system). Over the same period, CLABSI events per 1,000 CVC days decreased from 0.624 to 0.362 (Figure 2)—a 42% decline.

Conclusion

Study findings show that our comprehensive bundle of interventions for CVC insertion and maintenance resulted in decreased rates of CLABSI.

New Therapies for Hepatitis C Virus

Hepatitis C virus (HCV), the major etiologic agent of "non-A, non-B hepatitis" was discovered 26 years ago. Even before its discovery, interferon-α (IFN) was already being used for treatment of this infection. The next two decades saw a series of incremental improvements of the IFN therapies by extending the duration of therapy, using IFN in combination with oral ribavirin, using pegylated IFN with ribavirin, and most recently adding oral compounds that inhibit the HCV replication (directly acting antivirals - DAAs) to that regimen. DAAs target multiple steps in the HCV life cycle and are now used in combination to treat HCV infection without the need of IFN. These IFN-free, oral DAAs regimens are highly efficacious, have minimal toxicity and are given for short duration. Approved DAAs can cure more then 90% of persons with chronic HCV infection, thereby reducing the risk of death from cirrhosis and hepatocellular carcinoma. However, these drugs are very expensive, and currently their exorbitant cost significantly restricts the access to this therapy for many HCV infected patients.

Challenges in the management of infections due to carbapenem-resistant Enterobacteriaceae

Carbapenem-resistant Enterobacteriaceae (CRE) infections are increasing and are associated with considerable morbidity and mortality. Members of the Emerging Infections Network treating CRE encountered difficulties in obtaining laboratory results and struggled with limited treatment options. In addition, many treated patients experienced an alarming degree of drug toxicity from CRE therapies.

Comparing Interferon- Release Assay with Tuberculin Skin Test Readings at 48-72 Hours and 144-168 Hours with Use of 2 Commercial Reagents

BACKGROUND

Despite widespread use, the tuberculin skin test (TST) has many limitations, including a requirement for a second visit between 48 and 72 hours. The goal of this study was to determine the reliability of a TST reading between 144 and 168 hours.

METHODS

Tuberculin antigen was applied into both forearms (Aplisol in one arm and Tubersol in the other, from single lots of each product) by the Mantoux method. Blood samples were obtained for interferon- gamma release assay. Subjects were seen at 48-72 hours for the initial (day 2) TST reading and returned at 144-168 hours for a second (day 7) reading.

RESULTS

A total of 116 subjects at increased risk for tuberculosis were studied; 25 (22%) had positive results at day 2 with Tubersol and 27 (23%) had positive results at day 2 with Aplisol. Overall agreement between Tubersol and Aplisol at day 2 was 93% (kappa = 0.80) and at day 7 was 94% (kappa = 0.76). Overall agreement between day 2 and day 7 was 89% for Tubersol and 86% for Aplisol. Discordant results between day 2 and day 7 occurred mostly in persons with a history of bacille Calmette-Guerin vaccination.

CONCLUSIONS

Subjects who fail to present at 48-72 hours for TST reading may still have a reliable TST reading at up to 168 hours. Aplisol and Tubersol reagents produce comparable results when compared with the interferon- gamma release assay.

Cutaneous zygomycosis following attempted radial artery cannulation

A 70-year-old man was seen in a hospital consultation for evaluation of cellulitis of the left arm. The patient had multiple medical problems, including advanced liver disease due to alcohol, diabetes mellitus, congestive heart failure, atrial fibrillation, chronic renal in sufficiency, and hypopituitarism requiring steroid replacement. Most recently, he was admitted to the intensive care unit, where he required intubation and mechanical ventilation support following respiratory failure secondary to pneumonia. At that time, an attempt was also made to place an arterial line in the left radial artery. The patient had multiple areas of ecchymosis on both arms. A large bulla was found on the lateral aspect of the left wrist several days after the attempted arterial line placement. Subsequently, the lesion drained serosanguineous fluid, and, during the next 2 days, it ulcerated with necrosis extending around the wrist and to the elbow. He was started on ampicillin/sulbactam and clindamycin for presumed necrotizing fasciitis. The surgical service performed a very limited debridement,which was partially limited by his coagulopathy from liver disease. The initial tissue culture was positive only for Enterococcus faecium. At the time of the consultation, his temperature was 95' F (35 degrees C), pulse 82 bpm, respirations 16 BPM, and blood pressure 101/56 mmHg. He was awake but not oriented or responsive. His cardiopulmonary exam was unremarkable. Abdominal exam disclosed ascites. His extremities were all grossly edematous with multiple ecchymoses. His left forearm had a circumferential area of ecchymosis and necrosis with macerated margins, sparing only the lateral ulnar epicondyle, and involving deeper structures of subcutaneous fat and muscle(Figures 1-2 showing evolution of the lesion in a period of 1 week). Small tissue clippings were taken from the edge of the lesion and placed on culture plates. By the next morning, the patient's tissue culture grew a mold, later identified as Rhizopus. Amphotericin B was initiated. Surgical intervention (wide debridement with potential conversion to amputation of the left arm) was considered to offer little benefit in view of the patient's multiple and severe comorbidities and his poor prognosis. Amphotericin B was then stopped; the patient died within a week from his multiple medical complications. The family refused an autopsy.

Lactobacillus paracasei continuous ambulatory peritoneal dialysis-related peritonitis and review of the literature

We describe the first case of continuous ambulatory peritoneal dialysis (CAPD)-related peritonitis due to Lactobacillus paracasei. It occurred in a 65-year-old patient with recurrent episodes of peritonitis while he was receiving a prolonged course of intraperitoneal vancomycin. L. paracasei should be considered in the differential diagnosis of pathogens in CAPD-related peritonitis, especially in patients receiving prolonged vancomycin or glycopeptide treatment.

Cyclo-oxygenase II inhibitors in the treatment of neoplastic fever

Neoplastic fever is relatively common in cancer patients. Naproxen is one of the most commonly used non-steroidal anti-inflammatory drugs for the treatment of neoplastic fever. Naproxen is associated with platelet dysfunction and gastrointestinal side effects. We substituted rofecoxib, a cyclooxygenase-II inhibitor, for naproxen in patients with a previous history of, or a newly diagnosed, neoplastic fever in whom naproxen was relatively contraindicated. In all patients the fever resolved completely without any side effects.

Complete resolution of refractory immune thrombocytopenic purpura after colectomy for ulcerative colitis

Immune thrombocytopenia (ITP) is a destructive thrombocytopenia caused by an autoantibody directed to platelet membrane antigens. Various immunological diseases have been associated with ITP, but an association between inflammatory bowel disease (IBD) and ITP is not well recognised. We report a case of refractory immune thrombocytopenia associated with ulcerative colitis that resolved after colectomy. Although the medical treatment of inflammatory bowel disease or splenectomy are usually enough to treat ITP, it may be necessary to do a colectomy in refractory patients.
