RESUMO
OBJECTIVE: To describe the genomic analysis and epidemiologic response related to a slow and prolonged methicillin-resistant Staphylococcus aureus (MRSA) outbreak. DESIGN: Prospective observational study. SETTING: Neonatal intensive care unit (NICU). METHODS: We conducted an epidemiologic investigation of a NICU MRSA outbreak involving serial baby and staff screening to identify opportunities for decolonization. Whole-genome sequencing was performed on MRSA isolates. RESULTS: A NICU with excellent hand hygiene compliance and longstanding minimal healthcare-associated infections experienced an MRSA outbreak involving 15 babies and 6 healthcare personnel (HCP). In total, 12 cases occurred slowly over a 1-year period (mean, 30.7 days apart) followed by 3 additional cases 7 months later. Multiple progressive infection prevention interventions were implemented, including contact precautions and cohorting of MRSA-positive babies, hand hygiene observers, enhanced environmental cleaning, screening of babies and staff, and decolonization of carriers. Only decolonization of HCP found to be persistent carriers of MRSA was successful in stopping transmission and ending the outbreak. Genomic analyses identified bidirectional transmission between babies and HCP during the outbreak. CONCLUSIONS: In comparison to fast outbreaks, outbreaks that are "slow and sustained" may be more common to units with strong existing infection prevention practices such that a series of breaches have to align to result in a case. We identified a slow outbreak that persisted among staff and babies and was only stopped by identifying and decolonizing persistent MRSA carriage among staff. A repeated decolonization regimen was successful in allowing previously persistent carriers to safely continue work duties.

BACKGROUND: Neurosurgery inpatients are oftentimes critically ill, and face significant stress, post-operative pain, and/or emotional distress. As a result, the use of non-pharmacologic, alternative therapies as adjuncts in surgical care may benefit this patient population. Hospital economics related to integrative services may also provide additional incentive to providing alternative therapies. This study characterizes and evaluates how Integrative Healing Services (IHS) affects patient pain levels and length of stay. We also performed a literature review to examine national trends in inpatient integrative healing. METHODS: An IHS team (e.g. acupuncture, healing touch, music therapy, pet therapy, and counseling) was incorporated into the treatment regimen of neurosurgery inpatients (with >4days of stay) with chronic or intractable pain, stress or depression, and/or patients intolerant to or who failed physical or occupational therapy. RESULTS: 34 charts were retrospectively reviewed, with 17 patients receiving IHS (11 cranial and 6 spine cases), and 17 age and gender matched controls receiving routine care (11 cranial and 6 spine patients). Overall, 71% (12/17) of patients had a reduction in pain medication consumption, with 55% (6/11) of cranial and 100% (6/6) of spine patients reporting a reduction compared to baseline. The average pre-treatment pain-scale score was 5.5 out of 10 across all patients, while the average post-treatment pain-scale score was 3 out of 10 (p<0.01). 59% of patients had improved mobility. The average length of stay in the IHS group was 12.6days, and 19.6days in the routine care group (range 4-45) (p<0.01). CONCLUSIONS: IHS intervention may be an effective option for treating pain and decreasing hospital length of stay. National trends support the use of integrative healing and will likely continue to increase as further studies are performed.
