Response to Shaughnessy (1) (BMJ Article)

In his November 2012 BMJ article (1) regarding iatrogenic infections caused by compounding pharmacies, Allen Shaughnessy reports “In the past year …… two deaths in Alabama are alleged to have occurred due to contaminated intravenous nutritional supplements provided by a compounding pharmacy.”

In fact, nine deaths occurred among 19 patients who developed Serratia marcescens bacteremia in six Alabama hospitals that were infusing contaminated total parenteral nutrition [TPN] solutions produced by a compounding pharmacy. (2-6)

Initially, during March 2011, five Serratia bloodstream infections were identified among patients receiving TPN at one Alabama hospital. Receipt of TPN from a single compounding pharmacy was identified as a common source. An investigation was conducted by the Food and Drug Administration [FDA], the Centers for Disease Control and Prevention [CDC], and the Alabama state department of health. A total of 19 case-patients (age range 38 to 94 years) from six hospitals were identified from 1/24/2011 to 3/14/2011. There were nine fatalities. The attack rate among adult TPN recipients for development of Serratia bacteremia was 35%.

Investigation of the pharmacy’s process for producing TPN solutions resulted in identification of multiple breaches involving compounding and sterilizing amino acids for TPN formulations: prolonged periods between compounding and sterilization (amino acids were mixed in water as early as 1-2 days prior to filtration); failure to pre-filter particulate matter out of solution; excessive particulate matter in the pre-filtered solution caused a reduction in flow across the 0.2 micron filter membrane, necessitating replacement of the filter anywhere from 1-5 times during the sterilization process; and, inadequate sampling for sterility testing.

Serratia marcescens was cultured from patients’ TPN bags, the amino acid mixing container, the amino acid stirrer, an open bag of L-valine amino acid powder, and a water faucet used by the pharmacy for the compounding process. Serratia marcescens isolates cultured from compounded preparations and environmental samples were indistinguishable from 14 case-patient blood isolates by pulsed-field gel electrophoresis. The investigation concluded that the pharmacy’s failure to follow recommended practices for high-risk compounding of an amino acid component of TPN resulted in the outbreak of Serratia bacteremia with a 47% fatality rate [see Table].

In April 2011, the Institute for Safe Medication Practices [ISMP] wrote the following regarding Alabama’s iatrogenic Serratia bacteremia outbreak:
“Any type of sterile compounding activities must be undertaken with great care and in compliance with the United States Pharmacopeia [USP] Chapter <797>. It is tragic events like this that compelled USP to first establish <797> …… Chapter <797> describes a network of systems and processes to prevent patient harm and fatality from microbial contamination and excessive bacterial endotoxins in compounded sterile preparations …… As we move forward and learn from this most recent (Alabama) outbreak, we are calling upon all state boards of pharmacy to expect compounding pharmacies to comply with all aspects of <797>, and to survey these pharmacies regularly to enforce compliance.” (7) In October 2011, Gupta and colleagues at the CDC underscored that in order to avoid similar outbreaks, pharmacies must understand and adhere to current guidelines for compounding sterile preparations. (4)

Despite an unprecedented decade-long [2001-2011] cascade of iatrogenic bacterial and fungal infection outbreaks (8-9) that generated numerous pleas for compounding-sterility-compliance, year 2012 would nevertheless proceed to be plagued by yet additional contamination outbreaks caused by compounding pharmacies: the 9-state 43-case outbreak of post-procedural fungal endophthalmitis (10) , and the ongoing 19-state outbreak of fungal infections [meningitis, stroke, paraspinal/spinal, peripheral joint] that has sickened 620 patients and caused 39 deaths as of 17 December 2012.
