IMPORTANCE Handoff miscommunications are a leading cause of medical errors. Studies comprehensively assessing handoff improvement programs are lacking. OBJECTIVE To determine whether introduction of a multifaceted handoff program was associated with reduced rates of medical errors and preventable adverse events, fewer omissions of key data in written handoffs, improved verbal handoffs, and changes in resident-physician workflow. DESIGN, SETTING, AND PARTICIPANTS Prospective intervention study of 1255 patient admissions (642 before and 613 after the intervention) involving 84 resident physicians (42 before and 42 after the intervention) INTERVENTIONS Resident handoff bundle, consisting of standardized communication and handoff training, a verbal mnemonic, and a new team handoff structure. On one unit, a computerized handoff tool linked to the electronic medical record was introduced.
MAIN OUTCOMES AND MEASURESThe primary outcomes were the rates of medical errors and preventable adverse events measured by daily systematic surveillance. The secondary outcomes were omissions in the printed handoff document and resident time-motion activity.RESULTS Medical errors decreased from 33.8 per 100 admissions (95% CI, 27.3-40.3) to 18.3 per 100 admissions (95% CI, 14.7-21.9; P < .001), and preventable adverse events decreased from 3.3 per 100 admissions (95% CI, 1.7-4.8) to 1.5 (95% CI, 0.51-2.4) per 100 admissions (P = .04) following the intervention. There were fewer omissions of key handoff elements on printed handoff documents, especially on the unit that received the computerized handoff tool (significant reductions of omissions in 11 of 14 categories with computerized tool; significant reductions in 2 of 14 categories without computerized tool). Physicians spent a greater percentage of time in a 24-hour period at the patient bedside after the intervention (8.3%; 95% CI 7.1%-9.8%) vs 10.6% (95% CI, 9.2%-12.2%; P = .03). The average duration of verbal handoffs per patient did not change. Verbal handoffs were more likely to occur in a quiet location (33.3%; 95% CI, 14.5%-52.2% vs 67.9%; 95% CI, 50.6%-85.2%; P = .03) and private location (50.0%; 95% CI, 30%-70% vs 85.7%; 95% CI, 72.8%-98.7%; P = .007) after the intervention.CONCLUSIONS AND RELEVANCE Implementation of a handoff bundle was associated with a significant reduction in medical errors and preventable adverse events among hospitalized children. Improvements in verbal and written handoff processes occurred, and resident workflow did not change adversely.
Recent studies suggest that androgen-driven alteration to the autocrine and paracrine factors produced by scalp dermal papilla (DP) cells may be a key to androgen-potentiated balding. Here, we screened dihydrotestosterone (DHT)-regulated genes in balding DP cells and found that dickkopf 1 (DKK-1) is one of the most upregulated genes. DKK-1 messenger RNA is upregulated in 3-6 hours after 50-100 nM DHT treatment and ELISA showed that DKK-1 is secreted from DP cells in response to DHT. A co-culture system using outer root sheath (ORS) keratinocytes and DP cells showed that DHT inhibits the growth of ORS cells, and neutralizing antibody against DKK-1 significantly reversed the growth inhibition of ORS cells. Analysis of co-cultured ORS cells showed a significant increment of sub-G1 apoptotic cells in response to DHT. Also, recombinant human DKK-1 inhibited the growth of ORS cells and triggered apoptotic cell death. In addition, DHT-induced epithelial cell death in cultured hair follicles was reversed by neutralizing DKK-1 antibody. Moreover, immunoblotting showed that the DKK-1 level is up in the bald scalp compared with the haired scalp of patients with androgenetic alopecia. Altogether, our data strongly suggest that DHT-inducible DKK-1 is involved in DHT-driven balding.
The combination of indirect laser photocoagulation and intravitreal bevacizumab injection was well tolerated and induced prompt regression of aggressive zone I ROP.
Preoperative presence of macular ischemia can be useful in predicting the outcome of visual acuity after intravitreal bevacizumab for macular edema due to BRVO. The early gainers who favorably responded to the initial intravitreal bevacizumab injection are most likely to benefit from the bevacizumab treatment.
OBJECTIVE:
Current guidelines recommend that egg-allergic patients receive an influenza vaccine skin test before the influenza vaccine. This study evaluated the safety of bypassing the skin test and administering graded doses of influenza vaccine to egg-allergic children.
METHODS:
We conducted a retrospective chart-review study of egg-allergic patients aged 6 months to 18 years who received the vaccine skin test and/or a 2-dose graded influenza vaccine. Between influenza seasons 2002–2003 and 2006–2007, egg-allergic patients underwent a vaccine skin test before influenza vaccine administration. Starting in 2006–2007, the skin test was removed from our protocol and egg-allergic patients received the influenza vaccine in 2 graded doses. All vaccinated patients were observed for adverse reactions.
RESULTS:
Two hundred sixty-one egg-allergic patients were evaluated for influenza vaccine administration, and 171 went on to receive the vaccine. Of the 56 patients who received the skin test before the influenza vaccine, 95% (exact 95% confidence interval [CI]: 85.1–98.9) tolerated the vaccine without a serious adverse reaction. This rate was unchanged after the vaccine skin test was removed from the protocol. Of the 115 patients who received the vaccine without a preceding skin test, 97% (exact 95% CI: 91.3–99.0) tolerated the vaccine without serious adverse reaction. The tolerance rate ratio was 1.01 (95% CI: 0.97–1.06).
CONCLUSION:
The results of our study suggest that egg-allergic patients without anaphylaxis to egg may safely receive the influenza vaccine in a 2-dose, graded fashion without a vaccine skin test.
