MedSafer: Glass Half-Empty or Half-Full?

 

 

 

We’ve done many columns on PIM’s (Potentially Inappropriate Medications) in the elderly and many on deprescribing. But does deprescribing actually translate into fewer adverse drug events (ADE’s)? The MedSafer Study was a study on electronic decision support for deprescribing in hospitalized older adults intended to answer this question.

 

MedSafer was a cluster randomized clinical trial of older (≥65 years) hospitalized patients with an expected survival of more than 3 months who were admitted to 1 of 11 acute care hospitals in Canada (McDonald 2022). Participants were taking 5 or more medications per day at the time of admission. Reports of deprescribing opportunities generated by MedSafer software were based on patients’ usual home medications and measures of prognosis and frailty.

 

Almost 6000 patients were enrolled. Deprescribing increased from 29.8% in control patients to 55.4% in intervention participants. There was no difference in adverse drug withdrawal events between groups. However, there was no significant difference in the primary outcome, ADE’s within 30 days of discharge (5.0% in controls vs 4.9% in intervention participants). The incidence of postdischarge falls did decrease but not statistically significantly (odds ratio, 0.76). Sleep and quality of life remained stable before and after hospitalization.

 

One problem was that, despite cluster randomization, groups were not balanced (participants in the intervention arm were older and had more PIMS prescribed at baseline). But sensitivity analyses, including addressing those imbalances, did not alter study conclusions.

 

The researchers had used a historical rate of ADE’s in the first 30 days following deprescribing to establish the power of the study. That rate, taken mostly from studies done more than 15 years ago, was 10 to 15%. But the rate of these ADE’s in both arms of the current study was much lower (5% and 4.9%). The authors also note that widespread hospital pharmacist involvement in medication reconciliation has created opportunities to mitigate more worrisome prescribing practices, such as errors of omission, which may lead to clearly identifiable ADE’s.

 

The authors also note that, while the intervention identified numerous deprescribing opportunities, many were for low-risk nonbeneficial polypharmacy (eg, nonstatin cholesterol-lowering medications or stool softeners) and deprescribing these medications is less likely to impact 30-day ADE’s. But that still has both patient and societal value (avoiding excess cost, waste, pill burden, etc.).

 

The authors had many suggestions for future studies on the impact of deprescribing on ADE’s (eg. more prolonged duration, focus on more high-risk PIM’s, etc.).

 

In sum, the study found that providing deprescribing decision support to the acute care medical teams did not impact 30-day ADE rates. But it did effectively stop many PIM’s, and did so safely, with no evidence of increased harm. So, is the glass half empty, or half full?

Urinary Catheter Reinsertion

 

 

In our many columns on CAUTI’s (catheter-associated urinary tract infections) there is one topic we have seldom discussed – reinsertion of urinary catheters. A recent study by researchers at Henry Ford Hospital (Jamil 2022) brought that issue to our attention.

 

While we have focused efforts on avoiding urinary catheters that don’t meet criteria, Jamil et al. point out that it is estimated 25%-45% of adult patients will have an indwelling urinary catheter inserted at some point during their hospitalization, with rates as high as 89% for patients within the ICU. And we’ve also focused efforts on prompt removal of those catheters once they no longer meet criteria for continued use. But what happens once we remove those catheters?

 

The researchers developed a post-catheter removal bladder management protocol referred to as the Urinary Catheter Alleviation Navigator Protocol (UCANP) and piloted this protocol on four units, a neuro-intensive care unit, 2 neurosurgical and/or neurologic step-down units, and a neurosurgical and/or neurologic general practice unit.

 

The protocol: After catheter removal, a post-void residual (PVR) was obtained if a spontaneous void occurred within the first 4 hours. Patients with a PVR ≤ 100 mL “graduated” from the post-catheter removal management protocol. Patients with a PVR ≥ 400 mL were initiated on the intermittent catherization pathway. Patients with a PVR between 100 and 400 mL were monitored with repeat bladder scans every 4 hours and followed the protocol suggested pathway depending on the repeat bladder scan volumes. Patients who did not spontaneously void within 4 hours or had a PVR ≥ 400 mL were started on the intermittent catherization pathway. Patients would undergo nurse-conducted intermittent catherization for 48 hours. If they were unable to void spontaneously by that time, the primary medical and nursing team would evaluate the patient’s cognitive and physical ability, family support status, post-discharge location (home vs skilled nursing center, long term acute care center, sub-acute rehab center etc.), and ability to continue self or care-assisted intermittent catherization after discharge.

 

After implementation of the protocol, the reinsertion rate of 16% was compared to 21% and 27% in the pre-pilot cohort and another historical cohort, respectively. The mean number of catheter days was significantly lower during the protocol period (1.4 days) compared to the pre-pilot (5.6 days) and other historical (9.5 days) cohorts (P = .006).  Rates of CAUTI’s were 0.6% during the pilot, compared to 1.2% in the pre-pilot cohort and 1.7% in the other historical cohort. Investigated in a larger patient population would be required to assess statistical significance regarding reduction in CAUTI’s.

 

Successful implementation of the protocol looks like it drew upon many of the success factors from the Michigan Keystone Project. All medical personnel (physicians, nurses, nursing assistants) were provided educational material and instructions on the outlined protocol. Comprehensive Unit-Based Safety Program (CUSP) principles were used and debriefings were held every 3 weeks by clinical leadership. The EMR was used for both order entry and tracking of patients, with reminders and instructions for nursing staff about next steps in the protocol.

 

We think this is an exciting study. If it results in reductions in catheter days of this magnitude in other populations and settings, we’d expect a significant reduction in CAUTI’s.

Predicting C. diff Infection in Just 6 Hours?

 

 

What if you could accurately predict in a timely fashion which of your hospitalized patients were likely to develop C. diff (Clostridiodes difficile) infection? You could institute prophylactic measures, make the diagnosis earlier, and implement infection control measures in a more timely fashion.

 

A new study looked at the ability of machine learning algorithms to predict which hospitalized patients will become infected with C. diff (Panchavati  2022). The study used electronic health record data from several hospitals to develop 3 machine learning algorithms and then tested the algorithms using data 1,149,088 inpatient encounters with 7,107 CDI (C. diff infection) encounters at other hospitals. They found that machine learning algorithms can predict future CDI in hospitalized patients using just the first 6 hours of inpatient data!

 

You’ll have to read the publication itself for details of each of the 3 machine learning algorithms and all the incorporated data elements. Age was one of the most important features in generating predictions in each of the 3 machine learning algorithms. Other data elements that were important predictors were sodium, BMI, white blood cell count, bilirubin, heart rate, diastolic blood pressure, active medication treatment with antibiotics or proton pump inhibitors (PPI’s).

 

The size and breadth of underlying data was a major strength of the study. The data came from EMR’s at over 700 US hospitals. The development dataset contained 13,664,840 inpatient encounters with 80,046 CDI encounters and the external validation dataset used data on 1,149,088 inpatient encounters with 7,107 CDI (C. diff infection) encounters at other hospitals. And fact that all the data was easily gleaned from the EMR makes potential use of these machine learning algorithms very attractive.

 

While we’ve always been able to use many of the above risk factors to identify patients at risk of developing CDI, the accuracy of these machine learning algorithms has the potential to significantly impact our approach to CDI.
