Transcription

1 Speaker Disclosure INFECTION CONTROL AND ANTIBIOTIC STEWARDSHIP Philip Sloane, MD, MPH Dr. Sloane has received antibiotic stewardship related research funding from grant #R18 HS and from task order contracts #HHSA I and #HHSA from the US Agency for HealthCare Research and Quality the Cecil G. Sheps Center for Health Services Research at the University of North Carolina at Chapel Hill Learning Objectives By the session s end, participants who remain awake will be able to: Identify the problems associated with antibiotic overprescribing in post acute and long term care settings State the core elements of effective antibiotic stewardship Discuss five situations in which antibiotics are commonly prescribed but seldom needed Describe five targets for measurement and benchmarking to use in antibiotic stewardship program, including those most likely to be required by CMS reporting Identify training resources to help medical providers and nursing staff practice antibiotic stewardship in post acute and long term care Crisis of Antibiotic Resistance Multi drug resistance increasingly common Over 20,000 deaths annually in U.S.A. from multidrug resistant infections Projected 317,000 deaths per year by

Antibiotics Are Overused Average # Antibiotic Prescriptions Per Resident in One Year * Antibiotic Overprescribing: THE Major Cause of Bacterial Resistance The Average: Nursing Home Resident 4.6 antibiotic prescriptions per year 1 prescription every 80 days On antibiotics 10% of the time Medical Experts Estimate that Between 25% and 75% of median Antibiotics Prescribed to Nursing Home Residents are Not Needed Nursing Home Resistant Bacteria Galore results of skin, airway, skin and wound cultures in 82 residents of a Michigan nursing home MRSA CR GNR VRE 18% J Clin Micro 50(5); , % 72% % of Nursing Home Residents with Positive Culture Reasons Antibiotics Are Prescribed Presumed Skin and Soft Tissue Infection Other Infection Respiratory Infection The most common other infection is C. difficile Presumed Urinary Infection The NEW NURSING HOME MANDATE CMS October 4, 2016: all nursing homes will be required, as part of infection control, to have: an infection control officer [deadline: November 28, 2016] An antibiotic stewardship program [deadline: November 28, 2017] /medicareand medicaid programs reformof requirements for long term care facilities) Yes, this is a policy change Prescribing antibiotics just in case was accepted in the past, but now antibiotics should be given after careful, evidence based consideration of risks and necessity. This process of assuring the right antibiotic at the right time and in the right dose and duration is referred to as antibiotic stewardship 2

3 Antibiotic Stewardship in Nursing Homes: Optimizing Antibiotic Use Results of Our Research and Quality Improvement Program <== Baseline Randomized Trial in 14 NHs Antibiotic Prescriptions Per 100 Resident Days Follow Up ==> Intervention Begun Mar Apr May Jun Jul Aug Sep Oct Nov Intervention Group All Indications Comparison Group All Indications 24% Reduction in Intervention Group Antibiotic Use at Beginning of Project, by Nursing Home 12 Working with a Nursing Home Chain Results after 1 year Average # Antibiotic Prescriptions Per Resident in One Year Jan Apr E J H G R D T F Y Q W V CC EE Nursing Home Was Antibiotic Prescribing Reduced? Did More People Get Sick? All Antibiotics Antibiotics for Suspected UTI Antibiotics for Respiratory Problems Antibiotics for skin problems Reduced by 19.5% Reduced by 19% Reduced by 22% Increased by 12% Hospitalization rate 30 day readmission rate Sepsis Reduced by 11% Reduced by 31% No increase noted 3

Reduced by 11% Reduced by 8% We don t know yet Average # Antibiotic Prescriptions Per Resident in One Year Jan Apr 2015 Jan Apr E J H G R D T F Y Q W V CC EE Nursing Home Issue #5: Does this person need antibiotics? Where to Start? The Five Most Common Errors in the Diagnosis and Management of Infections in Long Term Care Settings 82 year old man; two weeks of increased swelling in both legs, that often goes down at night. One week history nontender, red rash on his right leg, which has been gradually growing in size and redness. Temperature 98.1; leg has mildly indurated, nontender, scaly bright red inflammation on the anterior and medial shin. Pulses palpable; no calf tenderness; Homan's sign negative; WBC 5,800 without a left shift; venous Doppler examination normal. Antibiotics for this wound? Fifth most common error: Thinking red skin means infected skin Does this need antibiotics? One week later 4

Fourth most common error: Prescribing the wrong antibiotic and/or too long a treatment duration 1 TMP SMX 3 days; Nitrofurantoin 5 days; 2 Varies with drug, No therapy required in most cases; 3 Not diabetic; 4 Minimum 5 days (should be afebrile hours); non ambulatory treat as HCAP; assess using score for severity Issue #3: Case Description Mr. Leonard, 76 year old nonsmoker 5 days of nasal congestion, sore throat and sneezing Hacking cough worse at night Decreased appetite, more tired Temp 99.4, other vitals normal, pulse ox 97% Placed on antibiotics Research Result: Cough Alone Increases 3x the likelihood of a LTC Patient Getting Antibiotics Question: Is cough alone a reason to give antibiotics? Why or why not? 5

Mrs. Jenkins, a 79 year old with stroke, incontinence Wet incontinence pad has odor No complaints Normal vital signs Nurse asks to have urine checked Is Cloudy or Smelly Urine a Reason To Give Antibiotics? Percent Yes No Nurses Geriatricians Geriatr Nurs Jul Aug;26(4): What Causes Changes in Urine Color or Odor? Diet Medications Dehydration Bacteria in urine If person is not sick, it s asymptomatic bacteriuria 6

Should you get a urine culture just in case? Antibiotic Prescribing Decision when the Culture was Ordered No antibiotic 179 cases (70%) Antibiotic 75 cases (30)% Ordering a Urine Culture: A Gateway to Overprescribing? results of 254 randomly sampled cultures Culture Result <100K or Neg = 68 Pos = 111 <100K or Neg = 21 Pos = 54 Prescribing Decision when the Result was Reported 17 (25%) were prescribed antibiotic 99 (89%) were prescribed antibiotic 2 (10%) stopped and 19 (90%) continued or changed antibiotic 0 (0%) stopped and 54 (100%) continued or changed antibiotic Received Full Antibiotic Course Second most common error: Over ordering urine cultures, and then treating the culture rather than the patient Bottom Line: 189 (74%) received a course of antibiotics, although 86% had a temperature less than 99 o F, 74% lacked documentation of any urinary tract specific signs or symptoms, and only 18% met the modified McGeer criteria for urinary tract infection. Why? Issue #1: Two Case Descriptions Mrs. White 84 year old with arthritis and moderate dementia Uncooperative with dressing Irritable Eats half of breakfast Says she s tired Ms. Blue 34 year old nurse Divorced, alone this weekend You were going to have lunch with her, but she cancels Low energy; not hungry Doesn t want to get dressed Doesn t want to deal with people 7

8 Both Have Similar Nonspecific Symptoms What You Might Think About Your Friend Ms. Blue Ms. White 84 year old with arthritis and moderate dementia Uncooperative with dressing Irritable Eats half of breakfast Says she s tired Ms. Blue 34 year old Divorced, alone this weekend Low energy ; not hungry Doesn t want to deal with people Doesn t want to get dressed Coming down with a virus Too much to drink last night Didn t sleep well Pain Stress Depression What the Nursing Supervisor Says About Ms. White Probably the urine. Needs an antibiotic. Most common error: Knee jerk reaction to look for a urine infection in every patient with nonspecific symptoms Thinking first of UTI when anything goes wrong with an old person is outdated knowledge that causes staff to jump to conclusions. 45 Jumping to conclusions In medical decision making the most common reason for medical errors What else could be causing Ms. White s fatigue, irritability, and poor appetite? The Big Seven: Common Reasons for Nonspecific Symptoms in Ms. White Dehydration Medication side effect Coming down with a virus Didn t sleep well Pain Constipation Stress / anxiety / depression 8

9 Active Interventions for Non Specific Symptoms Assess hydration status (and encourage fluids) Review current medications Look for signs of a respiratory or GI virus Think about sleep problems Ask about pain / discomfort Ask about constipation Look for sources of stress, anxiety or depression Monitor symptoms and vital signs (especially temperature) Use nursing interventions where appropriate Should we get a urine culture just in case Tips on Developing an Antibiotic Stewardship Program in Your Organization Importance of Leadership Interviews with 182 nursing staff and 50 medical providers from 31 nursing homes showed: Strong support for reducing antibiotic use DONs and nurse specialists felt more empowered to make changes than other nurses Medical specialists (e.g. geriatricians) felt more empowered and committed to change The Challenge of Leadership Turnover One year turnover rate in NC Nursing Homes: Administrator 25% Director of Nursing 54% Infection Control Nurse 57% Foster a Leadership Team Laboratory Medical Director Infection Control Nurse Focus on Communication Data and QAPI Consultant Pharmacist Director of Nursing 9

REVIEW, RECOMMEND AND NOTIFY Dealing with Resident and Family Expectations Case Example Satisfaction is not severely impacted when antibiotics not given Communication and education are key BMJ Sep 5;317(7159): Cochrane Database Syst Rev Apr 30:4. J Gen Intern Med Nov 6 Example: What to Say to the Family of a Man with a Viral Bronchitis Advise on what to expect: His cough might last several more days to several weeks, and it may take him a while to feel better. Respond to concerns about symptoms: We re going to help him feel more comfortable so his body can fight this virus. He ll need plenty of fluids and rest. Also, we ll give medicine for his fever and cough, and keep an eye on him. If Family Specifically Asks for an Antibiotic Prescription Mr. Leonard s chest cold is caused by a virus, and antibiotics won t help viruses. Giving him antibiotics when they aren t needed can cause side effects and may mean the antibiotics won t work when he really needs them. 11

12 Data Are Crucial CMS will require data monitoring and reporting Data are necessary for quality assessment and performance improvement (QAPI) Comparison data is helpful Statistics must be gathered regularly Rates should be computed Include urine culture results Core Outcomes Selected Process Measures Suggested QAPI Measures C difficile infection rate * MRSA infection rate * Urine infection treatment rates * Antibiotic prescriptions / 1,000 residentdays Percent of time on antibiotics Urine cultures: multidrug resistance rate Rate of hospitalization for sepsis Rate of fever among persons who had antibiotics initiated Average antibiotic prescription duration Urine cultures per 1,000 resident days * Current National Healthcare Safety Network (NHSN) measures Components of the UNC Antibiotic Stewardship QAPI Program We Provided Ongoing Training Resources for.

Between 25 75% prescriptions do not meet clinical guidelines. Few new antibiotics are being developed; so we need to preserve what we have. Why is this important? Health and well being of nursing home residents is the goal of care. Inappropriate overuse of antibiotics leads to serious complications.
